Abstract
The invention concerns a device for the vertical arrangement of a pole or postlike object (4) on a securing device (6) disposed at the ground end. The device comprises a substantially cylindrical, elongate mounting mandrel (10) which can be inserted into an accommodating bore (12) in the underside of the pole or post-like object (4). The device further comprises a support plate (16) from whose plane the mounting mandrel (10) extends upwards and on which the underside (14) of the pole or post-like object (4) rests. At least one securing projection (18) protrudes upwards from the support plate (16) and penetrates the material of the pole or post-like object (4). The mounting mandrel (10) is substantially thinner than the accommodating bore (12) in the underside of the pole or post-like object (4) such that there is considerable play between the journal or mounting mandrel (10) and the bore (12) surrounding the mandrel in the underside of the pole or post. Owing to this play, the pole or post (4) can be mounted on the mounting mandrel (10) such that the pole or post is tilted or inclined within a given angular range. This inclined or tilted position permits compensation of any positions of the securing device (6) disposed at the ground end which are lopsided relative to the vertical.

The invention xelates to a devi~e for the vertical arrange~Lent o~ a pole or post-like object on a securing devi~e disposeo ~t the groun~ end ac~ording to the prea~le of claim 1.
When erecting poles or posts, ~or instance when erecting a fence, when put~ing up a road sign or the like, the p~blem alwi~y~ arising is to maintain the pole or pO5~ in the exactly vertical position, if possible. The vertical locating of ~ pole or post may be effected, for ~Stahce, ~y checking and possibly correcting the ~ertical arrangement by means of a ~atex le~el or a pl~ line when a pole or post is secured o~ ~n~hored in the ground by dri~ing it in or i~bed~ing it in concrete. That is trou~lesome and time-consuming, ~ecause when driving ~ pole or post into the ground, for instance, the driving operation has to be repeatedly intex~upted in order to chec:k ~nd pos~ ly co~ect the location of the pole or post. When imbedding a pole or post in co~crete, the ex~ctly vertic~l arrangement of the sa~e can ~e corrected without difficulties before the concrete has set" ~owe~e~ ~ean$ hdve ~o be ~pplied to m~intain this exactly vertical position until the concrete has set so that this vertical position can no longer be changed by itself; that is, the pole or post ~s to be later~lly supported or briced, for ins~nce.
Apart ~om driving o~ digging a pole or post in or else imbeddi~ in G~ncrete~ it is known to ~se $e¢u~ing devi~es which can ~e anchored in the ground which then support the pole or post-like o~ject on their upper free end. The securing device adapted to be anchored in the ground comprises, for exa~ple, a wo~ or screw which is d~illed into the ground like a corkscrew, whereupon the polle or post i~ then screwed to this securing device ox inserted into the same. It is further known to integrally ~orm the pole or post-like object and ~he securihg device to be ~nchored in ~he ~round like a ~orkscrew so that; the pole or post-like object includes at one of its free e~lds ~he securinq device which is then scre~ed into the ground and anchored hereih With this method or ~hese possi~ilitiec ~f erectlng a pole or post, too, substantially the same problems are arising regarding the vertical arr~hgement of the pole o~ post as when dxiving the latter in or imbedding it in concrete. Instead o~ the driving operation the screwing of the se~ring device into the ground must be repeatedly inte~rupte~ in order to secure the later vertic~l position of the pole or post by appropriate ~easuring and possi~ly correcting steps.
From DE-G~ 89 03 236 a s~curing device fo~ wooden bea~s or the lik:e, especi~lly for wooden designs of playground climbing frames has beoome known. This known device co~prises a sec~ring de~icé disposed at the ground end in the form of an ~nchoring member to ~e anchored in the g~ound or i~ a foundation and ~
support me~ber arran~ed hereon and adapted to be positively en~aged with the pole or post. The support member is vertic~lly extending journal which is held in a recess in the underside of the post such that the post closely fits around the jollrnal, i.e. in a practlcally positive-locking ~anner.
Furthermore there is pxo~ided ~ resting surface or supPort plate for the post ~rom whose plane the journal extends u~ards arld on which the underside of the post rests. The support plate further has a ci~cumferentlal toothed ring which digs into ~he front ~y applyinç~ st~okes onto the upper end of the post and provides a fixing of the position in the transverse di~ectioh.
As an addition~l prote~tion against remov~l or detachment a transversel~ extending pin is provided which horizontally passes both through the material of the post and through the material of the joux~al. B~ the post shoe according to ~ 9 03 236 the post or pole is supported at a particular distance above the ground so that it is bettex protected against weather CA 02226965 l998-02-l2 influences due to raih, ~now or the like as well as against vermins and weeds, Although by the pole shoe i~ccording to I)E-GM 8~ 03 236 the ob;ect ~iven there can be achieved and substantially no p~oblems ha~re to be expecte~ as regards a loosenin~ of the securing device, ~ecause the pole is slipped onto the ~ournal subst~h~ially without ~orce - e~cept for the ~ppli~ation of a stroke to the upper end ~r t~is pole shoe or this securing devi~e has the essential draw~ack, however, th~t due to the narrow positive-locklng surrounding of the journal by the materlal of the pole or post the pole shoe itself ~us~ be anchored exactly vertically in the ground so as to ensure a vertical positlon of the pole or post held he~eby.
The generic DE-GM ~3 13 260 suggests an adjusting device p~ovided between a securing de~ice a~apted to be anchored in the ground, for i~stance a ~round screw, and the pole or po-~t-like object to be secu~ed he~eto. In accordahce with an e~odiment of DE-GM 93 13 ~60, this adjusting de~ice substantially comprises a cylindrica~ elongated mounting mandrel projecting upwards from the free upper side of the securing device and being adapted to be inserted into an accommod~ting bore in the ~nderside of the pole or post-~ike obj e~t. ~he axial extension of the mounting ~nd~el an~ the depth of the accommo~ating bore are selecte~ such that the former is somewha~ longer than is the depth of the latter so th~t, when slipping the pole or post-like ob~ect onto the mauntin~ ~ndrel, the free end of the l~ter rest~ on the bo~tom of the ~ccommodating bore. The pole or post-like ob}ect is now maintained in ~n exactly vertical position - possi~ly wi~h the ~id of a plum~ line or a water level -, where~pon ohe or several strokes are applied to the ~pper end of the object so that the free encl Or the mountlng mandrel penetrates the bottom of the blind bo~e and thus the object is fixed in it~
exactly ~ertic~1 position vis-~-vis the securing device.
The subject-matter of D~-GM 93 13 260 has widely proved su~¢e$sful in practice; neve~theless, it has again the minor defect that - as in the case of DE-~M 89 03 236 - ~ue to ~he ~ ow positive-locking surrounding of the journal by the materi~l of the pole or post, the pole shoe lts~lr must b~
;~nchored exac:tly ve~tic~lly ~h the ground so as to ensure vertica.l position of the pole or post held hereby. As for the rest, also the pole shoe accordin~ to DE-G~ 89 03 236 may cause problems with respect to a loosening of the se~uring de~ice dispo~ed at the gro~nd slde, if the material of the pole or post ls especlally har~ so th~t a partic~ expe~dit~re of energy is necessary to ~orce the toothed ring into the front of the post or pole. Although DE-GM 93 13 2~0 in further co~figurations suggests adjusting devices between the post and the securing device to be able to maintain the post in an exactly verti~al position, even i~ the securing device is mounted in the ground obliquely or out-of-perpendicular, these ~djusting devices ~re rather complicated and thus expensive, however.
Compared to thi~, it is the object of the present invention to provide a device for the vertical arrangement of a ~ole or post-like object on a se~uring device disposed ~t the ground end, in which after the securing dev~ce dlsposed st the gro~nd end has been anchored the ex~ctly vertic~l pos~tion of the pole or post-like object to be fixed hereto can be adjusted subsequently but permanently, wherein the arrangement of the securihg device in the ~round cannot be changed or loosened during this adjusting operation.
This object is achieved, according to the invention, by the featuxes described in claim 1.
Ac~ording to the invention, a possibility of vertical positioning or adjustment is pro~ided in a surprisingly simple manner ~y the f~ct that the mounting mandrel is substantially thinner than the acco~modati~g bore in the underside of the pole or post-like object s~ch that betweeh the ou~er periphery of t~e ~ounting mandrel and the inner circumferential area of ~he accom~o~ating bore a play is provided seen substantially over the enti~e axia~ extension of the mounting mandrel. In other words, in contxast to t~e teaching of P~-G~ 89 03 236 or ~E-GM 93 13 260 in which the ~terial of the pole or post fits around the m~n~rel or ~ournal in a posltive-locklng manner, there is considerable pl~y between t~e journal or ~ounting ~ahdrel and the bore surrounding the mandrel at the underside of the pole or post between the outer periphery of the ~oun~ing m~nd~el and the inner clrcumferential area of the accommodatlng bore seen substantially o~er the entlre axial exten~ion o* t~e mounting mandrel. Owing to this play, the pole or p~st can be ~ounted on the mounting mandrel such that the pole of post is tilted or inclined within a given angular ran~e, this in~lihed or tilted position permitting compensation of any positions of the securing device disposed at the ground end which are lopsided relative to the vertical Advantageous further developments of the invention cons~itute the sub~ect-matter o~ the su~claims.
Prefera~ly a plurality of securing projections extend upwards from the support plate on which the underside of the pole or post-like object is supported, as this is known per ~e from ~-~M 89 03 236. ~ereby the flxing of the pole or post-li~e object in any relative position is i~proved with respe~t to t~e device according to the invention.
As an alternative to that, the securin~ projection extending upwards from the support plate may have the shape of a closed circumferential ring. Here~y the same advantages cah be obtained as with the configuration in which a pl~rality of ihdi~idu~l sec~ring projections is provided.
The at least one securing projection is preferably bevelled in a blade-like m~nner at it~ free upper side. In this way, the at least one securing projection can penetrate the material o~ the pole or po~t-like o~ject. If the blade-like be~elling e~tends toward the longit~Ai~l axis of ~he device according to the invention, t~e ~isk of ~ursting or tearing up the material of the pole or post-like object when the at least one securing projection penetrates is inimi zed.
In a preferred embodi~ent that mounting mandrel has a tubula~ shape and is likewise blade-like bevelled at its upper circum~erentlal edge. Hereby not only at least one securing projection digs into the material of the pole or post-like ob~ect, but the mounting mandrel, too, penetra~es the material of the object ~t the front wall of the accommodating bo~e.
The mounting ~ndrel may have at its upper end portion a thro~gh bore extending substantially hori70ntally through w~ich a pln having a dimension smaller than specified passes. The pin extends to fit exactly in a transverse bore which is formed in the po~e or post~ e ob~ect in true alignment with the thro~gh bore in the ~ounting mandrel. This meas~re eonstitutes a protection against removal or detachment such that the pole or post-like object can no longer ~e easily remo~ed from the device according to the invention ~y tensile forces directed vertically up~ards. ~oreover, this securing possi~ility offers the advantage that e~en high posts to whose upper ends strokes cannot or can applied only with difficulties due to their ~ertieal extension can be safely clampe~ Also in the case of poles ~r posts for which no striking or drlving tool can/must be used due to particular requirements (e.g. to prevent the upper end from splintering or indent~ng ~y a striking tool) this securing possibility is especially ad~antageous. As the pin passing through the thro~gh bore in the mounting mandrel has a dimension sm~ller than specified, this pin doe~ not impede possibly necessary tilting movements of the pole or post-like object for the ~ertical arr~ngement thereof.
~ he pin is preferably a setscrew which is screwe~ in the transverse bore in the pole or post-li~e object. Hereby the pin oan only be loosened by an appropriate tool so that an increased connecting safety is ensure~.
Preferably the support plate can ~e ~erti~ally adjusted alon~ the mounting mandrel. This entails the advantage tha~ at ~rst the relative length of the ~ounting mandrel can ~e exactly adapted to the accommod~ting bore introduced into the pole or post-like object. Fhrthermore, hereby the pole or post-like object can be braced at ~he ~evi~e according to the invention - in particular in connection with the embodiment in~luding the horizontally extending pin. In accordance with a preferre~ embodiment, the support plate is vertica~ly adjusted in that t~e support plate rests on a base plate w~ich, in tu~n, is in threaded engagement with the outer periphery of the ~ounting mandrel. By a rotation of the base plate at the thread o~ the mounting mandrel the base plate also moves vertically up- or downwards and acoordingly entrains the support plate.
In a~cordance with another pref~rred embodiment, the mounti~g man~rel may comprise t~o coaxial tubular sections, t~e outer tubular section being vertically movable with respect to the inner tubular section and, in the case of ~ vertical ~p~ard~ movement of the outer tubular section, the s~e is horizontally or radiall~ e~tended in its upper end portion.
This enables that the mounting m~ndrel digs inside the ac~ommodating bore of the pole or post-like object so that a protection against re~o~l or detachment is ensured. The outer tubular section preferably has a~ its upper end portion a plurallty of deformable tongues which, in the case of a vertical ~pward displacement of the outer tubular section, stop at fixed counter-profiles of the inner tubular section and are horizont:ally~radially beht ~y them. ~his repre-qents another preferred embodiment of the pr~sent in~ention, because hereb~ a reliable protection against removal or de~a~hment ls ensured by si~ple ~onstructional means.
Moreovex, ~c~o~ing to a configuration of the invention, the support plate can be desi~ed ihtegrally with the securing device. This configuration h~s an esp~cially simple structure and handling as any movable parts are ~issing.
If, in accordance with ancther configuration, the support plate is a component separate from the $ecur~ng device which c~n be fastened to the lower front of the pole or po$t-like objec~ and which m~kes a frictional and/or positive connection ~ith ~t least a par~ial area of the outer periphery of the mo~nting mandrel, ~hen the mo~nting mandrel is inserted in the accommodating ~ore in the underside of the pole or post-like ob~ec~, no strong stroke or strokes has~have to be applied ~o the upper end of the pole or post-like object to fix the underside or the front of the pole or post-like obj ect on the support plate ~nd on the at least one securing projection the~eof, resp., in order to further dri~e, in addition to driving the upper end of the mounting man~rel into the bottom of the acoommodating bore, the at least one securing projection lnto the front of the pole or post-like object. Thus the effort is sub$~ntially re~uced and the forces acting on the securing device disposed at the ground end when fixing the pole or post-like ob~ect are thus likewise red~ced as well as, consequently, possible dangers of loosening. Hereby ~ possibility of ~ertically positioning or a~ustlng the pole or post-like object is provided in a simple way, the risk that the ~nchoring device disposed in the ground is loosened when fixing this obj~t being avoided.
In the last men~ioned embodiment the support plate preferably comp~ises a central opening the circumferential edge of which is in frictional andJo~ positive-locking contact with at least a partial area of the outer periphery o~ the mounting mandrel~ This is an embodiment of the support plate which is easy to manuf~cture but can be handled in practice with a minimum effort to ~ix the same to the mo~ntin~ mandrel.
The opening ~ay have a polygon~l or round cross-section, depending on the cross-sec~ion of the mounting ma~drel ~nd the possibly exi~tlng requirements. However, in practice a roun~
cross-section will probably turn out parti~ularly advantageous regarding the costs and efforts of manufacture ~oth for the mounti~g ~andrel ~n~ the accommodatlng bore in the underside of the pole or post-like object and for the ~nufacture of the opening in the suppo~t plate itself.
The inside di~meter of the opening is at most equal to, but pre~erably s~aller than the o~tsi~e diameter of the mo~nting mandrel. Hereby and especially when, accordin~ to another pre ferr~d embodiment, the opening in the support plate is ~urrounded by a plurality of resilient tongues, the opening of the support plate is automa~ically anchored to the mounting mandrel This locking effect can be intensified and thus further im~roved by the fsct that at least a partial area of the outer peripher~ of the mountihg m~ndrel has a knurl. Especially in combina~ion with the preferxed em~odiment that the openin~ in t~e support pl~te is ~urrounded by a pluxality o~ resilient tongues, whereby the insi~e ~iAmeter of the opening is furthermore smaller than the outside diameter Or the mounting ~andrel~ a rellable fixing of the position and especially a protection against distortion of the attached polo or post-like obiQct is brought about ~y ~he ~act that the points of the retaining tongues penetrate the knurls p~ovided at the mounting mandrel ~ -- 10 --Further details, aspects and advantage~ of the present invention are res~lting from the following description of several embodiments by way of the figures, where fig. 1 is ~ disassemble~ view of an embodiment of the present invention in the dismounted state;

The following description of preferred embodiments of the present invention has to be considered as purely illustrating and exemplary; the representation of the figu~es ~n~ the correspon~ing descrlptlon shall not be understood to be restrictin~.
Fig. 1 shows a first embodiment of the present invention for the verti~al arr~ngement of ~ pole or post-like object (in the following referred to as Rpole") on a securing device disposed at the g~o~nd end.
The figures 1 and 2 represent an embodi~ent of a device 2 ~c~ording to the invention which serves for the vertical arrangement of a pole 4 on a se~uring device 6 adapted to ~e anchored in the ground, fo~ example. The securing device 6 c~n be dug into the ground or i he~ed in concrete or can ~e screwed into the ground preferably like a corkscrew. A
particularly preferred embodi~ent of the se~uring device 6 is described in DE-GM 93 13 258 of the same applicant. Herewith reference is fully made to the content of ~isclosure of that document.
In the embodiment of the device 2 iLlustrated in figures 1 and 2 the device comprises at the upper free end of the securing device ~ a stepped portion or step a cen~rally supporting a tubular mounting mandrel 10. As one can best take from fig. 2 - the outside dia~eter of the mounting mandrel 10 is definitely s~aller than the inside diameter of an a~ommodating or blind bore 12 formed at the ~ower free end of the pole 4. ~he de~th of the b~re 12 is preferably smaller than the height of the mountlng mandrel 10 in this case.
A support plate lG can be disposed between the step 8 and a front 14 of the pole 4 where the ~ore 12 is introduced. The support plate is ad~pted as to its shape and surface to the sh~pe ~nd surfa~e of the front 14, i.e. it is ~sually circular as s~own in figures 3 and 4. A~ least one, preferably several securing proje~tions 18 extend up~ards fro~ the upper side of the support plate 16 in the clirection of the front 14. ln thiS
case, according to the drawing, a plurality of securing projections ~8 in the form of prongs, ti~es or spikes m~y extend upwards from the support plate 16, or else the securing projection 18 has the shape of a closed circumferential ring surrounding the periphery of the support plate 1~.
~ he securing pro~ectionts) 18 is/are pre~erably blade-like bevelled at its~their upper free endts)~ the bevelling ex~ending toward the central longitUdinal axis of the de~ice 2.
. -12-In the same way, the upper free edge of the mounting mandrel 10 is blade-like bevelled. If the blade-like bevellings extend toward the longit~inAl axis of the device 2 accor~lng to the invention, the risk of a b~xsting or cr~cking open of the material of the pole q while the projections are penetrating is ~1 nl~1 zed.
The fixing of the pole 4 on the device 2 is effect-ed such that ~t first ~he securlng de~ice 6 is anchored in the ground, for instan~e by screwing it in or imbedding it in conc~ete.
Af~e~ that the suPPort plate 16 is put on the underside or front 14 of the pole 4 and connected with the front 14. To this effect, the securing projections 18 which penetrate the ~ater~al of the pole 4, when one or more h G er strokes are appl~ed to ~he suppor~ plat~ 16, are provided at the support plate 16. Alternatively to the embodiment of the securing projections la shown in the figures 1 and 2 in the fo~ of prong or tine-like points penetxatin~ the materi~l of the pole g, the securing projection 18 may - as mentioned i~ the foregoing ~lready - have the shape of ~ closed circumferential ~ing surroun~ing the periphery of the support plate 16. As another alternative, accordin~ to fig. 3 a plurality of bores 20 wh~ch pe~mit nails or t~cker clips or the like to penetrate the m~te~ of the support plate 16 with the aid of such securing means on the front of the pole 4 ~ay be pro~ide~ in the support plate 16 so tha~ the support pl3te 16 can be fastened. In any case the support plate 16 has a ~entral opening 2Z which is formed in the support plate 16 such th~t it ls substantially in alignment ~ith the bore 12 in the lower end portion of the pole 4 after the support plate 16 has been attached to the front 14.
~ fter ~tt~chTng the s~ppo{t plate 16 the pole 4 according to fig. 1 is mounted on the securing device 6 f~om the top, the mounting m~ndrel 10 being introduced in the bore lZ through the opening 22 by a pre~etermined force. In this case the pole 4 . -13-rests on the upper edge of the mounting mandrel 10 with a base 24 ~ ~he ~ore 12 According to fig. 2, then the pole 4 is tilted - preferably with the aid of a plumb line or a water level - in such a way that possible in~linations of the securing device 6 are compensated and the pole 4 is arranged exa~tly ~e~ti~ally. The pole 4 is enabled to be tilted with respect to the securing device 6 by the fact th~t the outside dia~meter of the ~Lounting mandrel 10 i5 definitely smal~er, a~cording to the lnventio~, than the inside di~meter of the bore 12 so that the ~ndrel 10 m~y extend obliquely or out-of-perpendicular inside the bore 12, ~s illustrated in fig. 2. As soon as the pole 4 is ~rranged exactly vertically, one or several strokes are applied to the upper free end of the pole 4 by a ha~mer or another suitable driving tool so that the upper ~ircumferentl~l edge of the mounting mandrel 10 digs into the ~ase 24 of the bore 12 and thu~, .according to ~ig. 2, the pole 4 is held with res~ect to the securing device 6.
Furthermore, interposihg the support plate 16 t~ the mounting mandrel 10, the pole 4 is hel~ closely to the step 8, wherein the support ~late 16 rests completely or partly -depending on the degree of tiltlng of the ~ole 4 - on the step 8.
The support plate 16 mounted on the mounting mandrel 10 in that the inside diameter of the openihg 22 is at most equal to, pre~erably smaller than the o~tside diameter of the mounting mandrel 10. Hereby a frictional and/or positive-loc~ing contact or connection of the support plate 1~ with at least a partial area of the outer perlphery of the mounting ~andrel 10 is effected so that the po~ition of the pole 4 is immova~ly fixed with re~pect to the securing de~ice ~. Thi~ frictional and~or positive-looking connectlon of the support plate 1~ and the opening 22 with the ~o~nting ~andrel 10 can ~e intensified by the fact that at least a partial area o~ the outer periphery of the mounting mandrel 10 is pro~ided with a knurl 26. The opening 22 in the s~pport pl~e 16 may, according to fig. 3, also be surrounded by ~ plurality of xesilient tong~es 2~ which elastically deform (i.e. bend upwards) when the pole 4 is sl-pped onto the mounting ~andrel 10, wherein the mounting ~ndrel 10 penetrat¢s the opening 22, so that especially in conne~tion with the knurl 26 the support plate 16 and thus the pole 4 is safely fixed with respect to the securing de~ice 6.
Due to the flexibility of the tongues 28, the pole 4 can be tilted ~ithin a ~ider range with respect to the mounting mandrel 10 and ~hus the se~urin.g device 6.
By the blade-like bevelli~ of the ~pper circumferential edge of the ~ounting mandre:l 10 this portion can easily penetrate the material of the pole 4. As furthermore the blade-li~e bevelling is effected ~ontinuously toward the central longitudinal axis of the de~Jice 2, no outwardly directed extending or bursting forces are exerted on the m~te~i31 of the pole 4 so that the en~ire lower portion of the pole 4 - with the exception of the penetrat;ed securing projection(s~ 18 -r~m~in.~ uni~paired and thus less suscepti~le to atmospheric influences, vermins, weeds or t:he like.
The ~ross-section of the opening 22 depends substantially on the cross-section of the mounting mandrel 10. That is, when the ~o~lntin~ mandrel 10 iS tu~ula~ ha~ring a circular cross-section, the opening ~2 equally has a preferably round cxoss-section, as shown in fi~. 3, wherein the resilient tongues 28 are poss~bly still provaded. ;Just ~s well the opening 22 may have a square ~ig. 4: continuous lines) or a polygonal (fig 4; ~roken lines) cross-sectioll. A polygonal cross-section of the opening 22 may also be used with a round cross-$ectlon of the mounting mandre~ 10. Even in the case of a square or polygo~al cross-section of the opening 22 resilient retaining tongues may ~e provlded.
Since the support plate 16 is secured to the front 14 of the pole 4 ~efore the pole ~1 is slipped onto the mounting ndrel 10 o~ the securing device 6, the forces required for fixing the pole 4 on the securing de~ice 6 are limited to those forces which are ~ecessary for slippin~ the pole 4 onto the mounting mandrel lO, the latter passing through the opening whi~h preferably has a dim~nRion smaller than specified, ~nd the forces necessar~ to press or drive the mandrel 10 into the base 24. So the risk that the securing device 6 can loosen in the ground by foxces applied to the pole 4 fo~ securing the s~me is substantially reduced.
Figures SA to 8 show further embodiments o~ ~he present invention for the vertical ar~angement of a pole ~r post-like object on a securing device disposed at the ground end.
ln the figures 5A to 8 equal reference numerals denote ~qual or corresponding parts '~s in the figures 1 to 3i the~e parts are not explained once again.
In the configu~ati~n Or the device 2 represented in figures 5A and 5B this device :includes at ~he upper free end of the sec~ring device 6 the stepped area or step a which, in turn, centrally supports the tubular mounting mandrel 10. Here the outsi~e diam~ter of the mo~nting mandrel 10 is - as can best be taken from ~ig. 5~ - definitely or su~stanti~lly smaller than the inside diameter of the accommodatin~ or blind bore 12. The depth of the bore 12 again is at most equal to, but preferably sligh~ly smalle:r than the height of the mounting mandrel 10.
At least one securing projection 18 extends upwards radially outwardly from the s1ep or the support plate 8. ~e~e a~ain a plurality of tine or spike-sh~ped securing projectio~s 18 can extend up~ards rrom the step ~ or else the securing projection 18 has the shape o~ the closed circumferential ring s~rrounding the step B.
In accc~rdance with figures 5A ~nd 5B as in t~e em~odimcnt of the figures 1 to 3, the 3ecuring pro~ec~ion(s) 18 is/are ~ . -l6-blade-like bevelled at their upper free end, the bevelling extending tow~rd the central longitudinal axis of the device 2.
In the same way the upper free edge of the ~ounting mandrel 10 is bevelled in a blade-like manner The pole 4 is secured on the devi~e 2 suc~ that ~t first the securing device 6 is again anchored in the ground, for instance ~y screwing it in or im~edding lt in concrete. After that the pole 4 is mounted fro:m the top on the securi~g ~e~ice 6 accordlng to fig. 5A, the mounting mandrel 10 being introduced in ~he bore 1~. ~he pole ~ re~ts wi~h its lowe~
surfac~ or front 14 on the se:curing projection(s) la and the front or base 24 of the bore 1~ rests on the upper edge of the ~ounting mandrel 10. Then, according to fig. 5~, t~e pole is ~ilted - preferably wi~h the aid of a plumber line or a water le~el - in such a ~ay that: possible inclinations of the securing device 6 are compensated and the pole g h~s an exactly verti~l po~ition. This tilting of the pole 4 with respect to the securing device 6 is permilted by the fact that t~e o~tside diameter of the mounting mandrel 10 is substantially smaller ~hah the inside diameter o~ ~he bore 12 so that the mandrel 10 can extend obliquely or out-of-pe~pendicular inside the bo~e 12, as shown in fig. 5B. As soon as the pole 4 is positioned exactly vertically, one or se~eral strong s~roke~ are applied to the upper free end of the pole 4 by a hammer or another suitable driving tool so thal the securing projection~s) 18 penetra~e(s) the lower area 14 of the pole 4 and, moreover, the upper circumferential edge o~ the mounting mandrel 10 pene~rates the front 24 o~ the ~ore 12 so that, according to fig. 5B, the pole 4 is held wi1h respect to the securing device 6. Furthermore, the pole 4 is supported with part of its lower surfa~e 16 on the step 8 which thus corresponds in its function together with the securing pro~ection~s~ 1~ to t~e suppor~ing plate 16 of the ~igures 1 to 3.
The em~odiment according to figures 5A and SB is sufficient, whenever during later use no up~ardly directed . . -17-tensile forces are applied, i.e. for inst~n~e in the case of supporting beams or girders absorbing pure $orces of pressure If, however, such upwardly directed tensile forces have to be expected, preferably one of t~le embodlments in ~ecordance ~ith the figures 1 to 3 or 6A to ~ is used.
In the figures 6A to 8 again eq~l re~erence numerals denote eq~al or corresponding parts to those in the figuxes 5A
and 5B.
According to fig. 6A, the device 2 there again comprises the mounting mandrel 10 which is preferably formed integrally with the securing de~ice. The mountin~ mandrel 10 includes substantially horizontally exten~ing through bore 30 at its upper ~ree end. Immediately adja~ent t~ the mounting mandrel 10 ~ male thre~d 32 which is engaqed with a female thread provided o~ a base plate 34 is forme~ at the securing de~ice 6. The suppo~t plate 16 which is free~ly movable along the male thread 32, i.e. is not engaged ~ith the male thre~d 32, rests on the upper side of the base plate 34. From the support plate 16 ~gain the securing projection(s) 18 ~xtend(s) upwards.
In accoxdance with fig. 6B, a horizontally extending pin 36 which is inserted in a horizontally extending bore 38 in the pole ~ passes the through bore 30. The pin 36 h~s considerably smaller ~im~nsion th~n specified ~is-~-vis the through bore 30 so that, according to fig. 6B, the pin 36 ~d thus the pole 4 can be tilt~3d with respect to the se~uring device 6, wherein, due to the smaller ~jmen~ion of the pin 36, the same c:an extend ~bli~uely ln the through bore 30.
Preferably the pi~ 36 is inserted to ~it ~xactly in the bore 38 of the pole 4, in a particul~rly preferred em~odiment it is screwed in so that the pin 36 is safely held in the pole 4.
- ~8 --For faster~ g the pole 4 ~n the sec~lring deviçe ~i ~t first the pole 4 is slipped from the top onto the mounting ~andrel 10 and subsequently it is secure~ by means of the pin 3~ in the bore 30. Thus the pin 36 prevents the pole 4 from being removed or det~ ched tow~rd the top. A~ter th~t the base plate 34 is rotated so that in the fi~ures ~A and 6B it is moved upwards along the male thread 32 and here~y entrains the support plate 16. While screwing up the base plate 34 and thus the support pl~te l~, the eeeuring projection ~s) ~ 8 pene~rate~s~ the lower face 14 of the pole 4, Accorc~ing to fig. 6B, the pole 4 may pos~lbly ~e tilted with respect to the securing device 6 before the base plate 34 is scxewed up in ordex to be ~ble to compens~te possible inclinations of the se~uring device 6. The pole 4 is br~ced at the s~curing device 6 in any desired pos tion by the base plate 34 a~d thus by the s~ppor~ plate 1~, on the one hand, and, on the o~her ~and, by the opera~ing connection serving as a protection against removal or detachme~t ~etwee~ t~e pin 36 ~nd the thro~gh bore ~0 Fig. 7 shows a modified embodiment of that shown in the figures ~A and 6B.
According to fig. 7 a ~olt ~2 extends upw~rds from the support plate l~i into the material of the pole 4 with a washer 40 being interpose~. The threaded portion of the bolt 42 is engaged with a female thread 44 formed in a pin 46 which extends substanti~lly horizontally in a bore 48 According to fig. 7, the pin 46 has a dimension smaller than specified vis-à-vis the bore 48. A hexagon head 50 of the ~olt 42 is a~essible vi~ a recesS 5~ in the $ecuring devi~e 6, the recess 52 extending over a certain amount of the peripher~, for instance 90~. The bolt 42 is rotated by an open-end spanner or ~ si~ilar tool which is attached to the bolt head 50 via the recess 52. As o~e ca~ take directly from ~ig . 7, when the ~olt 42 is tightened the threaded portion o~ the bolt 42 is moved upwards rel~tive to the pin 46 ~nd this upward movernent of the bolt is ~onverted into a do~ward mo~ement of the pole 4 in l9 fig. 7 due to the ar~anyement of the pin 46 in the bore 48 so th~t the securing projection~s~ 18 penetrate(s) the lower fa~e of ~he pole 4 ~nd the tubular mou~tlng mandrel 10 penetrates the front f~ce 24 o~ the bore 12 ln the pole 4 so that the pole 4 is fixed with respect to the securing de~i~e 6.
Fig ~ shows a further e~bodiment of the present in~ention. The embodiment acco:rding to fig. 8 distinguishes in particular by the f~ct that the moun~ing m~ndrel 10 ~onsi~ts of two coaxial tubular sections, namely an outer tubular section 54 and an inner tubular section 56. The outer tubula~ section 54 is preferably formed at ils lower end portion inte~rally with the support plate 16 including the securing pro~ec~ion 18 projecting ~pwards herefrom. The support plate 16 rests, as in the embodiment according to i-i~ures 6A and 6B, on the b~se plate 34 which is engaged with an outer threaded portion at the mountin~ mandrel 10 and the inner tubular section 56, respectively. At the upper free end portion the inner tubul~r section 56 is expanded to be :Eunnel-shaped in the way visible from fig. 8 and the outer tubu]ar section 54 has a plurality of ~ongues 58. The tonyues 58 are formed ih th~t the material of the outer tubular section 54 is provide~ with a plurality of recesses 60 in the upper free end portion. The ~onical or funnel-shaped expansion of the inner tubular section 56 forms a correspondln~ly conical or funnel-shaped counter-face 62 to which the tongues 5B are adjacent For securing a pole not represented in fig. 8 on the device 2 according to the invention in a~ordance with fig~ 8, the pole is slipped onto the mounting mand~el 10 s~ th~ the underside of the pole rests on the bl~de-like bevelling of the securing projection~s~ 18. Then the base plate 34 is rotated -possibly ~y a suita~le tool - upwards on the inner tubular section 56 along the outer threaded portion, ~hereby the support plate 16 in fig. ~ is likewise moved upwards. This upward move~ent of the support plate l~ i5 transmitted via the outer tubular section 54 to the tongues 58 so that the tongues 58 are bent substantially h~iz:ontally or radially outwardly by the conical coun~er-face 62 and penetrate the mate~ial of the pole inside of that bore 12. At the same time, the securing projections 18 penetrate the unde~side of the p~le so that the pole is safely supported. Although it is not showFl in fig 8, it is understood that also in this embodiment the bore in the pole i9 inter~e~ing vis-a-~ris the mounting mandrel 10 so that the vertical arr~ngement can be corrected, if necessary, before finally tightening or clamping the pole.

The invention xelates to a devi~e for the vertical arrange~Lent o~ a pole or post-like object on a securing devi~e disposeo ~t the groun~ end ac~ording to the prea~le of claim 1.
When erecting poles or posts, ~or instance when erecting a fence, when put~ing up a road sign or the like, the p~blem alwi~y~ arising is to maintain the pole or pO5~ in the exactly vertical position, if possible. The vertical locating of ~ pole or post may be effected, for ~Stahce, ~y checking and possibly correcting the ~ertical arrangement by means of a ~atex le~el or a pl~ line when a pole or post is secured o~ ~n~hored in the ground by dri~ing it in or i~bed~ing it in concrete. That is trou~lesome and time-consuming, ~ecause when driving ~ pole or post into the ground, for instance, the driving operation has to be repeatedly intex~upted in order to chec:k ~nd pos~ ly co~ect the location of the pole or post. When imbedding a pole or post in co~crete, the ex~ctly vertic~l arrangement of the sa~e can ~e corrected without difficulties before the concrete has set" ~owe~e~ ~ean$ hdve ~o be ~pplied to m~intain this exactly vertical position until the concrete has set so that this vertical position can no longer be changed by itself; that is, the pole or post ~s to be later~lly supported or briced, for ins~nce.
Apart ~om driving o~ digging a pole or post in or else imbeddi~ in G~ncrete~ it is known to ~se $e¢u~ing devi~es which can ~e anchored in the ground which then support the pole or post-like o~ject on their upper free end. The securing device adapted to be anchored in the ground comprises, for exa~ple, a wo~ or screw which is d~illed into the ground like a corkscrew, whereupon the polle or post i~ then screwed to this securing device ox inserted into the same. It is further known to integrally ~orm the pole or post-like object and ~he securihg device to be ~nchored in ~he ~round like a ~orkscrew so that; the pole or post-like object includes at one of its free e~lds ~he securinq device which is then scre~ed into the ground and anchored hereih With this method or ~hese possi~ilitiec ~f erectlng a pole or post, too, substantially the same problems are arising regarding the vertical arr~hgement of the pole o~ post as when dxiving the latter in or imbedding it in concrete. Instead o~ the driving operation the screwing of the se~ring device into the ground must be repeatedly inte~rupte~ in order to secure the later vertic~l position of the pole or post by appropriate ~easuring and possi~ly correcting steps.
From DE-G~ 89 03 236 a s~curing device fo~ wooden bea~s or the lik:e, especi~lly for wooden designs of playground climbing frames has beoome known. This known device co~prises a sec~ring de~icé disposed at the ground end in the form of an ~nchoring member to ~e anchored in the g~ound or i~ a foundation and ~
support me~ber arran~ed hereon and adapted to be positively en~aged with the pole or post. The support member is vertic~lly extending journal which is held in a recess in the underside of the post such that the post closely fits around the jollrnal, i.e. in a practlcally positive-locking ~anner.
Furthermore there is pxo~ided ~ resting surface or supPort plate for the post ~rom whose plane the journal extends u~ards arld on which the underside of the post rests. The support plate further has a ci~cumferentlal toothed ring which digs into ~he front ~y applyinç~ st~okes onto the upper end of the post and provides a fixing of the position in the transverse di~ectioh.
As an addition~l prote~tion against remov~l or detachment a transversel~ extending pin is provided which horizontally passes both through the material of the post and through the material of the joux~al. B~ the post shoe according to ~ 9 03 236 the post or pole is supported at a particular distance above the ground so that it is bettex protected against weather CA 02226965 l998-02-l2 influences due to raih, ~now or the like as well as against vermins and weeds, Although by the pole shoe i~ccording to I)E-GM 8~ 03 236 the ob;ect ~iven there can be achieved and substantially no p~oblems ha~re to be expecte~ as regards a loosenin~ of the securing device, ~ecause the pole is slipped onto the ~ournal subst~h~ially without ~orce - e~cept for the ~ppli~ation of a stroke to the upper end ~r t~is pole shoe or this securing devi~e has the essential draw~ack, however, th~t due to the narrow positive-locklng surrounding of the journal by the materlal of the pole or post the pole shoe itself ~us~ be anchored exactly vertically in the ground so as to ensure a vertical positlon of the pole or post held he~eby.
The generic DE-GM ~3 13 260 suggests an adjusting device p~ovided between a securing de~ice a~apted to be anchored in the ground, for i~stance a ~round screw, and the pole or po-~t-like object to be secu~ed he~eto. In accordahce with an e~odiment of DE-GM 93 13 ~60, this adjusting de~ice substantially comprises a cylindrica~ elongated mounting mandrel projecting upwards from the free upper side of the securing device and being adapted to be inserted into an accommod~ting bore in the ~nderside of the pole or post-~ike obj e~t. ~he axial extension of the mounting ~nd~el an~ the depth of the accommo~ating bore are selecte~ such that the former is somewha~ longer than is the depth of the latter so th~t, when slipping the pole or post-like ob~ect onto the mauntin~ ~ndrel, the free end of the l~ter rest~ on the bo~tom of the ~ccommodating bore. The pole or post-like ob}ect is now maintained in ~n exactly vertical position - possi~ly wi~h the ~id of a plum~ line or a water level -, where~pon ohe or several strokes are applied to the ~pper end of the object so that the free encl Or the mountlng mandrel penetrates the bottom of the blind bo~e and thus the object is fixed in it~
exactly ~ertic~1 position vis-~-vis the securing device.
The subject-matter of D~-GM 93 13 260 has widely proved su~¢e$sful in practice; neve~theless, it has again the minor defect that - as in the case of DE-~M 89 03 236 - ~ue to ~he ~ ow positive-locking surrounding of the journal by the materi~l of the pole or post, the pole shoe lts~lr must b~
;~nchored exac:tly ve~tic~lly ~h the ground so as to ensure vertica.l position of the pole or post held hereby. As for the rest, also the pole shoe accordin~ to DE-G~ 89 03 236 may cause problems with respect to a loosening of the se~uring de~ice dispo~ed at the gro~nd slde, if the material of the pole or post ls especlally har~ so th~t a partic~ expe~dit~re of energy is necessary to ~orce the toothed ring into the front of the post or pole. Although DE-GM 93 13 2~0 in further co~figurations suggests adjusting devices between the post and the securing device to be able to maintain the post in an exactly verti~al position, even i~ the securing device is mounted in the ground obliquely or out-of-perpendicular, these ~djusting devices ~re rather complicated and thus expensive, however.
Compared to thi~, it is the object of the present invention to provide a device for the vertical arrangement of a ~ole or post-like object on a se~uring device disposed ~t the ground end, in which after the securing dev~ce dlsposed st the gro~nd end has been anchored the ex~ctly vertic~l pos~tion of the pole or post-like object to be fixed hereto can be adjusted subsequently but permanently, wherein the arrangement of the securihg device in the ~round cannot be changed or loosened during this adjusting operation.
This object is achieved, according to the invention, by the featuxes described in claim 1.
Ac~ording to the invention, a possibility of vertical positioning or adjustment is pro~ided in a surprisingly simple manner ~y the f~ct that the mounting mandrel is substantially thinner than the acco~modati~g bore in the underside of the pole or post-like object s~ch that betweeh the ou~er periphery of t~e ~ounting mandrel and the inner circumferential area of ~he accom~o~ating bore a play is provided seen substantially over the enti~e axia~ extension of the mounting mandrel. In other words, in contxast to t~e teaching of P~-G~ 89 03 236 or ~E-GM 93 13 260 in which the ~terial of the pole or post fits around the m~n~rel or ~ournal in a posltive-locklng manner, there is considerable pl~y between t~e journal or ~ounting ~ahdrel and the bore surrounding the mandrel at the underside of the pole or post between the outer periphery of the ~oun~ing m~nd~el and the inner clrcumferential area of the accommodatlng bore seen substantially o~er the entlre axial exten~ion o* t~e mounting mandrel. Owing to this play, the pole or p~st can be ~ounted on the mounting mandrel such that the pole of post is tilted or inclined within a given angular ran~e, this in~lihed or tilted position permitting compensation of any positions of the securing device disposed at the ground end which are lopsided relative to the vertical Advantageous further developments of the invention cons~itute the sub~ect-matter o~ the su~claims.
Prefera~ly a plurality of securing projections extend upwards from the support plate on which the underside of the pole or post-like object is supported, as this is known per ~e from ~-~M 89 03 236. ~ereby the flxing of the pole or post-li~e object in any relative position is i~proved with respe~t to t~e device according to the invention.
As an alternative to that, the securin~ projection extending upwards from the support plate may have the shape of a closed circumferential ring. Here~y the same advantages cah be obtained as with the configuration in which a pl~rality of ihdi~idu~l sec~ring projections is provided.
The at least one securing projection is preferably bevelled in a blade-like m~nner at it~ free upper side. In this way, the at least one securing projection can penetrate the material o~ the pole or po~t-like o~ject. If the blade-like be~elling e~tends toward the longit~Ai~l axis of ~he device according to the invention, t~e ~isk of ~ursting or tearing up the material of the pole or post-like object when the at least one securing projection penetrates is inimi zed.
In a preferred embodi~ent that mounting mandrel has a tubula~ shape and is likewise blade-like bevelled at its upper circum~erentlal edge. Hereby not only at least one securing projection digs into the material of the pole or post-like ob~ect, but the mounting mandrel, too, penetra~es the material of the object ~t the front wall of the accommodating bo~e.
The mounting ~ndrel may have at its upper end portion a thro~gh bore extending substantially hori70ntally through w~ich a pln having a dimension smaller than specified passes. The pin extends to fit exactly in a transverse bore which is formed in the po~e or post~ e ob~ect in true alignment with the thro~gh bore in the ~ounting mandrel. This meas~re eonstitutes a protection against removal or detachment such that the pole or post-like object can no longer ~e easily remo~ed from the device according to the invention ~y tensile forces directed vertically up~ards. ~oreover, this securing possi~ility offers the advantage that e~en high posts to whose upper ends strokes cannot or can applied only with difficulties due to their ~ertieal extension can be safely clampe~ Also in the case of poles ~r posts for which no striking or drlving tool can/must be used due to particular requirements (e.g. to prevent the upper end from splintering or indent~ng ~y a striking tool) this securing possibility is especially ad~antageous. As the pin passing through the thro~gh bore in the mounting mandrel has a dimension sm~ller than specified, this pin doe~ not impede possibly necessary tilting movements of the pole or post-like object for the ~ertical arr~ngement thereof.
~ he pin is preferably a setscrew which is screwe~ in the transverse bore in the pole or post-li~e object. Hereby the pin oan only be loosened by an appropriate tool so that an increased connecting safety is ensure~.
Preferably the support plate can ~e ~erti~ally adjusted alon~ the mounting mandrel. This entails the advantage tha~ at ~rst the relative length of the ~ounting mandrel can ~e exactly adapted to the accommod~ting bore introduced into the pole or post-like object. Fhrthermore, hereby the pole or post-like object can be braced at ~he ~evi~e according to the invention - in particular in connection with the embodiment in~luding the horizontally extending pin. In accordance with a preferre~ embodiment, the support plate is vertica~ly adjusted in that t~e support plate rests on a base plate w~ich, in tu~n, is in threaded engagement with the outer periphery of the ~ounting mandrel. By a rotation of the base plate at the thread o~ the mounting mandrel the base plate also moves vertically up- or downwards and acoordingly entrains the support plate.
In a~cordance with another pref~rred embodiment, the mounti~g man~rel may comprise t~o coaxial tubular sections, t~e outer tubular section being vertically movable with respect to the inner tubular section and, in the case of ~ vertical ~p~ard~ movement of the outer tubular section, the s~e is horizontally or radiall~ e~tended in its upper end portion.
This enables that the mounting m~ndrel digs inside the ac~ommodating bore of the pole or post-like object so that a protection against re~o~l or detachment is ensured. The outer tubular section preferably has a~ its upper end portion a plurallty of deformable tongues which, in the case of a vertical ~pward displacement of the outer tubular section, stop at fixed counter-profiles of the inner tubular section and are horizont:ally~radially beht ~y them. ~his repre-qents another preferred embodiment of the pr~sent in~ention, because hereb~ a reliable protection against removal or de~a~hment ls ensured by si~ple ~onstructional means.
Moreovex, ~c~o~ing to a configuration of the invention, the support plate can be desi~ed ihtegrally with the securing device. This configuration h~s an esp~cially simple structure and handling as any movable parts are ~issing.
If, in accordance with ancther configuration, the support plate is a component separate from the $ecur~ng device which c~n be fastened to the lower front of the pole or po$t-like objec~ and which m~kes a frictional and/or positive connection ~ith ~t least a par~ial area of the outer periphery of the mo~nting mandrel, ~hen the mo~nting mandrel is inserted in the accommodating ~ore in the underside of the pole or post-like ob~ec~, no strong stroke or strokes has~have to be applied ~o the upper end of the pole or post-like object to fix the underside or the front of the pole or post-like obj ect on the support plate ~nd on the at least one securing projection the~eof, resp., in order to further dri~e, in addition to driving the upper end of the mounting man~rel into the bottom of the acoommodating bore, the at least one securing projection lnto the front of the pole or post-like object. Thus the effort is sub$~ntially re~uced and the forces acting on the securing device disposed at the ground end when fixing the pole or post-like ob~ect are thus likewise red~ced as well as, consequently, possible dangers of loosening. Hereby ~ possibility of ~ertically positioning or a~ustlng the pole or post-like object is provided in a simple way, the risk that the ~nchoring device disposed in the ground is loosened when fixing this obj~t being avoided.
In the last men~ioned embodiment the support plate preferably comp~ises a central opening the circumferential edge of which is in frictional andJo~ positive-locking contact with at least a partial area of the outer periphery o~ the mounting mandrel~ This is an embodiment of the support plate which is easy to manuf~cture but can be handled in practice with a minimum effort to ~ix the same to the mo~ntin~ mandrel.
The opening ~ay have a polygon~l or round cross-section, depending on the cross-sec~ion of the mounting ma~drel ~nd the possibly exi~tlng requirements. However, in practice a roun~
cross-section will probably turn out parti~ularly advantageous regarding the costs and efforts of manufacture ~oth for the mounti~g ~andrel ~n~ the accommodatlng bore in the underside of the pole or post-like object and for the ~nufacture of the opening in the suppo~t plate itself.
The inside di~meter of the opening is at most equal to, but pre~erably s~aller than the o~tsi~e diameter of the mo~nting mandrel. Hereby and especially when, accordin~ to another pre ferr~d embodiment, the opening in the support plate is ~urrounded by a plurality of resilient tongues, the opening of the support plate is automa~ically anchored to the mounting mandrel This locking effect can be intensified and thus further im~roved by the fsct that at least a partial area of the outer peripher~ of the mountihg m~ndrel has a knurl. Especially in combina~ion with the preferxed em~odiment that the openin~ in t~e support pl~te is ~urrounded by a pluxality o~ resilient tongues, whereby the insi~e ~iAmeter of the opening is furthermore smaller than the outside diameter Or the mounting ~andrel~ a rellable fixing of the position and especially a protection against distortion of the attached polo or post-like obiQct is brought about ~y ~he ~act that the points of the retaining tongues penetrate the knurls p~ovided at the mounting mandrel ~ -- 10 --Further details, aspects and advantage~ of the present invention are res~lting from the following description of several embodiments by way of the figures, where fig. 1 is ~ disassemble~ view of an embodiment of the present invention in the dismounted state;

In the embodiment of the device 2 iLlustrated in figures 1 and 2 the device comprises at the upper free end of the securing device ~ a stepped portion or step a cen~rally supporting a tubular mounting mandrel 10. As one can best take from fig. 2 - the outside dia~eter of the mounting mandrel 10 is definitely s~aller than the inside diameter of an a~ommodating or blind bore 12 formed at the ~ower free end of the pole 4. ~he de~th of the b~re 12 is preferably smaller than the height of the mountlng mandrel 10 in this case.
A support plate lG can be disposed between the step 8 and a front 14 of the pole 4 where the ~ore 12 is introduced. The support plate is ad~pted as to its shape and surface to the sh~pe ~nd surfa~e of the front 14, i.e. it is ~sually circular as s~own in figures 3 and 4. A~ least one, preferably several securing proje~tions 18 extend up~ards fro~ the upper side of the support plate 16 in the clirection of the front 14. ln thiS
case, according to the drawing, a plurality of securing projections ~8 in the form of prongs, ti~es or spikes m~y extend upwards from the support plate 16, or else the securing projection 18 has the shape of a closed circumferential ring surrounding the periphery of the support plate 1~.
~ he securing pro~ectionts) 18 is/are pre~erably blade-like bevelled at its~their upper free endts)~ the bevelling ex~ending toward the central longitUdinal axis of the de~ice 2.
. -12-In the same way, the upper free edge of the mounting mandrel 10 is blade-like bevelled. If the blade-like bevellings extend toward the longit~inAl axis of the device 2 accor~lng to the invention, the risk of a b~xsting or cr~cking open of the material of the pole q while the projections are penetrating is ~1 nl~1 zed.
The fixing of the pole 4 on the device 2 is effect-ed such that ~t first ~he securlng de~ice 6 is anchored in the ground, for instan~e by screwing it in or imbedding it in conc~ete.
Af~e~ that the suPPort plate 16 is put on the underside or front 14 of the pole 4 and connected with the front 14. To this effect, the securing projections 18 which penetrate the ~ater~al of the pole 4, when one or more h G er strokes are appl~ed to ~he suppor~ plat~ 16, are provided at the support plate 16. Alternatively to the embodiment of the securing projections la shown in the figures 1 and 2 in the fo~ of prong or tine-like points penetxatin~ the materi~l of the pole g, the securing projection 18 may - as mentioned i~ the foregoing ~lready - have the shape of ~ closed circumferential ~ing surroun~ing the periphery of the support plate 16. As another alternative, accordin~ to fig. 3 a plurality of bores 20 wh~ch pe~mit nails or t~cker clips or the like to penetrate the m~te~ of the support plate 16 with the aid of such securing means on the front of the pole 4 ~ay be pro~ide~ in the support plate 16 so tha~ the support pl3te 16 can be fastened. In any case the support plate 16 has a ~entral opening 2Z which is formed in the support plate 16 such th~t it ls substantially in alignment ~ith the bore 12 in the lower end portion of the pole 4 after the support plate 16 has been attached to the front 14.
~ fter ~tt~chTng the s~ppo{t plate 16 the pole 4 according to fig. 1 is mounted on the securing device 6 f~om the top, the mounting m~ndrel 10 being introduced in the bore lZ through the opening 22 by a pre~etermined force. In this case the pole 4 . -13-rests on the upper edge of the mounting mandrel 10 with a base 24 ~ ~he ~ore 12 According to fig. 2, then the pole 4 is tilted - preferably with the aid of a plumb line or a water level - in such a way that possible in~linations of the securing device 6 are compensated and the pole 4 is arranged exa~tly ~e~ti~ally. The pole 4 is enabled to be tilted with respect to the securing device 6 by the fact th~t the outside dia~meter of the ~Lounting mandrel 10 i5 definitely smal~er, a~cording to the lnventio~, than the inside di~meter of the bore 12 so that the ~ndrel 10 m~y extend obliquely or out-of-perpendicular inside the bore 12, ~s illustrated in fig. 2. As soon as the pole 4 is ~rranged exactly vertically, one or several strokes are applied to the upper free end of the pole 4 by a ha~mer or another suitable driving tool so that the upper ~ircumferentl~l edge of the mounting mandrel 10 digs into the ~ase 24 of the bore 12 and thu~, .according to ~ig. 2, the pole 4 is held with res~ect to the securing device 6.
Furthermore, interposihg the support plate 16 t~ the mounting mandrel 10, the pole 4 is hel~ closely to the step 8, wherein the support ~late 16 rests completely or partly -depending on the degree of tiltlng of the ~ole 4 - on the step 8.
The support plate 16 mounted on the mounting mandrel 10 in that the inside diameter of the openihg 22 is at most equal to, pre~erably smaller than the o~tside diameter of the mounting mandrel 10. Hereby a frictional and/or positive-loc~ing contact or connection of the support plate 1~ with at least a partial area of the outer perlphery of the mounting ~andrel 10 is effected so that the po~ition of the pole 4 is immova~ly fixed with re~pect to the securing de~ice ~. Thi~ frictional and~or positive-looking connectlon of the support plate 1~ and the opening 22 with the ~o~nting ~andrel 10 can ~e intensified by the fact that at least a partial area o~ the outer periphery of the mounting mandrel 10 is pro~ided with a knurl 26. The opening 22 in the s~pport pl~e 16 may, according to fig. 3, also be surrounded by ~ plurality of xesilient tong~es 2~ which elastically deform (i.e. bend upwards) when the pole 4 is sl-pped onto the mounting ~andrel 10, wherein the mounting ~ndrel 10 penetrat¢s the opening 22, so that especially in conne~tion with the knurl 26 the support plate 16 and thus the pole 4 is safely fixed with respect to the securing de~ice 6.
Due to the flexibility of the tongues 28, the pole 4 can be tilted ~ithin a ~ider range with respect to the mounting mandrel 10 and ~hus the se~urin.g device 6.
By the blade-like bevelli~ of the ~pper circumferential edge of the ~ounting mandre:l 10 this portion can easily penetrate the material of the pole 4. As furthermore the blade-li~e bevelling is effected ~ontinuously toward the central longitudinal axis of the de~Jice 2, no outwardly directed extending or bursting forces are exerted on the m~te~i31 of the pole 4 so that the en~ire lower portion of the pole 4 - with the exception of the penetrat;ed securing projection(s~ 18 -r~m~in.~ uni~paired and thus less suscepti~le to atmospheric influences, vermins, weeds or t:he like.
The ~ross-section of the opening 22 depends substantially on the cross-section of the mounting mandrel 10. That is, when the ~o~lntin~ mandrel 10 iS tu~ula~ ha~ring a circular cross-section, the opening ~2 equally has a preferably round cxoss-section, as shown in fi~. 3, wherein the resilient tongues 28 are poss~bly still provaded. ;Just ~s well the opening 22 may have a square ~ig. 4: continuous lines) or a polygonal (fig 4; ~roken lines) cross-sectioll. A polygonal cross-section of the opening 22 may also be used with a round cross-$ectlon of the mounting mandre~ 10. Even in the case of a square or polygo~al cross-section of the opening 22 resilient retaining tongues may ~e provlded.
Since the support plate 16 is secured to the front 14 of the pole 4 ~efore the pole ~1 is slipped onto the mounting ndrel 10 o~ the securing device 6, the forces required for fixing the pole 4 on the securing de~ice 6 are limited to those forces which are ~ecessary for slippin~ the pole 4 onto the mounting mandrel lO, the latter passing through the opening whi~h preferably has a dim~nRion smaller than specified, ~nd the forces necessar~ to press or drive the mandrel 10 into the base 24. So the risk that the securing device 6 can loosen in the ground by foxces applied to the pole 4 fo~ securing the s~me is substantially reduced.
Figures SA to 8 show further embodiments o~ ~he present invention for the vertical ar~angement of a pole ~r post-like object on a securing device disposed at the ground end.
ln the figures 5A to 8 equal reference numerals denote ~qual or corresponding parts '~s in the figures 1 to 3i the~e parts are not explained once again.
In the configu~ati~n Or the device 2 represented in figures 5A and 5B this device :includes at ~he upper free end of the sec~ring device 6 the stepped area or step a which, in turn, centrally supports the tubular mounting mandrel 10. Here the outsi~e diam~ter of the mo~nting mandrel 10 is - as can best be taken from ~ig. 5~ - definitely or su~stanti~lly smaller than the inside diameter of the accommodatin~ or blind bore 12. The depth of the bore 12 again is at most equal to, but preferably sligh~ly smalle:r than the height of the mounting mandrel 10.
At least one securing projection 18 extends upwards radially outwardly from the s1ep or the support plate 8. ~e~e a~ain a plurality of tine or spike-sh~ped securing projectio~s 18 can extend up~ards rrom the step ~ or else the securing projection 18 has the shape o~ the closed circumferential ring s~rrounding the step B.
In accc~rdance with figures 5A ~nd 5B as in t~e em~odimcnt of the figures 1 to 3, the 3ecuring pro~ec~ion(s) 18 is/are ~ . -l6-blade-like bevelled at their upper free end, the bevelling extending tow~rd the central longitudinal axis of the device 2.
In the same way the upper free edge of the ~ounting mandrel 10 is bevelled in a blade-like manner The pole 4 is secured on the devi~e 2 suc~ that ~t first the securing device 6 is again anchored in the ground, for instance ~y screwing it in or im~edding lt in concrete. After that the pole 4 is mounted fro:m the top on the securi~g ~e~ice 6 accordlng to fig. 5A, the mounting mandrel 10 being introduced in ~he bore 1~. ~he pole ~ re~ts wi~h its lowe~
surfac~ or front 14 on the se:curing projection(s) la and the front or base 24 of the bore 1~ rests on the upper edge of the ~ounting mandrel 10. Then, according to fig. 5~, t~e pole is ~ilted - preferably wi~h the aid of a plumber line or a water le~el - in such a ~ay that: possible inclinations of the securing device 6 are compensated and the pole g h~s an exactly verti~l po~ition. This tilting of the pole 4 with respect to the securing device 6 is permilted by the fact that t~e o~tside diameter of the mounting mandrel 10 is substantially smaller ~hah the inside diameter o~ ~he bore 12 so that the mandrel 10 can extend obliquely or out-of-pe~pendicular inside the bo~e 12, as shown in fig. 5B. As soon as the pole 4 is positioned exactly vertically, one or se~eral strong s~roke~ are applied to the upper free end of the pole 4 by a hammer or another suitable driving tool so thal the securing projection~s) 18 penetra~e(s) the lower area 14 of the pole 4 and, moreover, the upper circumferential edge o~ the mounting mandrel 10 pene~rates the front 24 o~ the ~ore 12 so that, according to fig. 5B, the pole 4 is held wi1h respect to the securing device 6. Furthermore, the pole 4 is supported with part of its lower surfa~e 16 on the step 8 which thus corresponds in its function together with the securing pro~ection~s~ 1~ to t~e suppor~ing plate 16 of the ~igures 1 to 3.
The em~odiment according to figures 5A and SB is sufficient, whenever during later use no up~ardly directed . . -17-tensile forces are applied, i.e. for inst~n~e in the case of supporting beams or girders absorbing pure $orces of pressure If, however, such upwardly directed tensile forces have to be expected, preferably one of t~le embodlments in ~ecordance ~ith the figures 1 to 3 or 6A to ~ is used.
In the figures 6A to 8 again eq~l re~erence numerals denote eq~al or corresponding parts to those in the figuxes 5A
and 5B.
According to fig. 6A, the device 2 there again comprises the mounting mandrel 10 which is preferably formed integrally with the securing de~ice. The mountin~ mandrel 10 includes substantially horizontally exten~ing through bore 30 at its upper ~ree end. Immediately adja~ent t~ the mounting mandrel 10 ~ male thre~d 32 which is engaqed with a female thread provided o~ a base plate 34 is forme~ at the securing de~ice 6. The suppo~t plate 16 which is free~ly movable along the male thread 32, i.e. is not engaged ~ith the male thre~d 32, rests on the upper side of the base plate 34. From the support plate 16 ~gain the securing projection(s) 18 ~xtend(s) upwards.
In accoxdance with fig. 6B, a horizontally extending pin 36 which is inserted in a horizontally extending bore 38 in the pole ~ passes the through bore 30. The pin 36 h~s considerably smaller ~im~nsion th~n specified ~is-~-vis the through bore 30 so that, according to fig. 6B, the pin 36 ~d thus the pole 4 can be tilt~3d with respect to the se~uring device 6, wherein, due to the smaller ~jmen~ion of the pin 36, the same c:an extend ~bli~uely ln the through bore 30.
Preferably the pi~ 36 is inserted to ~it ~xactly in the bore 38 of the pole 4, in a particul~rly preferred em~odiment it is screwed in so that the pin 36 is safely held in the pole 4.
- ~8 --For faster~ g the pole 4 ~n the sec~lring deviçe ~i ~t first the pole 4 is slipped from the top onto the mounting ~andrel 10 and subsequently it is secure~ by means of the pin 3~ in the bore 30. Thus the pin 36 prevents the pole 4 from being removed or det~ ched tow~rd the top. A~ter th~t the base plate 34 is rotated so that in the fi~ures ~A and 6B it is moved upwards along the male thread 32 and here~y entrains the support plate 16. While screwing up the base plate 34 and thus the support pl~te l~, the eeeuring projection ~s) ~ 8 pene~rate~s~ the lower face 14 of the pole 4, Accorc~ing to fig. 6B, the pole 4 may pos~lbly ~e tilted with respect to the securing device 6 before the base plate 34 is scxewed up in ordex to be ~ble to compens~te possible inclinations of the se~uring device 6. The pole 4 is br~ced at the s~curing device 6 in any desired pos tion by the base plate 34 a~d thus by the s~ppor~ plate 1~, on the one hand, and, on the o~her ~and, by the opera~ing connection serving as a protection against removal or detachme~t ~etwee~ t~e pin 36 ~nd the thro~gh bore ~0 Fig. 7 shows a modified embodiment of that shown in the figures ~A and 6B.
According to fig. 7 a ~olt ~2 extends upw~rds from the support plate l~i into the material of the pole 4 with a washer 40 being interpose~. The threaded portion of the bolt 42 is engaged with a female thread 44 formed in a pin 46 which extends substanti~lly horizontally in a bore 48 According to fig. 7, the pin 46 has a dimension smaller than specified vis-à-vis the bore 48. A hexagon head 50 of the ~olt 42 is a~essible vi~ a recesS 5~ in the $ecuring devi~e 6, the recess 52 extending over a certain amount of the peripher~, for instance 90~. The bolt 42 is rotated by an open-end spanner or ~ si~ilar tool which is attached to the bolt head 50 via the recess 52. As o~e ca~ take directly from ~ig . 7, when the ~olt 42 is tightened the threaded portion o~ the bolt 42 is moved upwards rel~tive to the pin 46 ~nd this upward movernent of the bolt is ~onverted into a do~ward mo~ement of the pole 4 in l9 fig. 7 due to the ar~anyement of the pin 46 in the bore 48 so th~t the securing projection~s~ 18 penetrate(s) the lower fa~e of ~he pole 4 ~nd the tubular mou~tlng mandrel 10 penetrates the front f~ce 24 o~ the bore 12 ln the pole 4 so that the pole 4 is fixed with respect to the securing de~i~e 6.
Fig ~ shows a further e~bodiment of the present in~ention. The embodiment acco:rding to fig. 8 distinguishes in particular by the f~ct that the moun~ing m~ndrel 10 ~onsi~ts of two coaxial tubular sections, namely an outer tubular section 54 and an inner tubular section 56. The outer tubula~ section 54 is preferably formed at ils lower end portion inte~rally with the support plate 16 including the securing pro~ec~ion 18 projecting ~pwards herefrom. The support plate 16 rests, as in the embodiment according to i-i~ures 6A and 6B, on the b~se plate 34 which is engaged with an outer threaded portion at the mountin~ mandrel 10 and the inner tubular section 56, respectively. At the upper free end portion the inner tubul~r section 56 is expanded to be :Eunnel-shaped in the way visible from fig. 8 and the outer tubu]ar section 54 has a plurality of ~ongues 58. The tonyues 58 are formed ih th~t the material of the outer tubular section 54 is provide~ with a plurality of recesses 60 in the upper free end portion. The ~onical or funnel-shaped expansion of the inner tubular section 56 forms a correspondln~ly conical or funnel-shaped counter-face 62 to which the tongues 5B are adjacent For securing a pole not represented in fig. 8 on the device 2 according to the invention in a~ordance with fig~ 8, the pole is slipped onto the mounting mand~el 10 s~ th~ the underside of the pole rests on the bl~de-like bevelling of the securing projection~s~ 18. Then the base plate 34 is rotated -possibly ~y a suita~le tool - upwards on the inner tubular section 56 along the outer threaded portion, ~hereby the support plate 16 in fig. ~ is likewise moved upwards. This upward move~ent of the support plate l~ i5 transmitted via the outer tubular section 54 to the tongues 58 so that the tongues 58 are bent substantially h~iz:ontally or radially outwardly by the conical coun~er-face 62 and penetrate the mate~ial of the pole inside of that bore 12. At the same time, the securing projections 18 penetrate the unde~side of the p~le so that the pole is safely supported. Although it is not showFl in fig 8, it is understood that also in this embodiment the bore in the pole i9 inter~e~ing vis-a-~ris the mounting mandrel 10 so that the vertical arr~ngement can be corrected, if necessary, before finally tightening or clamping the pole.
