Description

Predlagani izum se nanaša na vezni element za palico po splošnem delu patentnega zahtevka 1.The present invention relates to a rod fastener according to the general part of claim 1.

Pri znanih ogrodjih ali prostorskih predale, j ih se predalke preko vozliščnih kosov pogosto med seboj poveže tako, da se končni del predalke razstavljivo privije na vozliščni kos, ki je stransko pritrjen na drugi predalki ali nosilnem stebru. Pri gradnji takšnega prostorskega predalčja običajno obstaja želja, da bi predalko vstavili npr. med dva vozliščna kosa, brez da bi ju prostorsko premikali,in da bi pred privitjem pustili prosto mesto za vijaka, ki sta pritrjena na končnih delih predalke.In the case of known frames or space drawers, the drawers are often interconnected through the hub pieces so that the end part of the drawers can be screwed apart to a hub piece that is laterally secured to another drawer or support column. When constructing such a space drawer, there is usually a desire to insert a drawer, e.g. between two hub pieces without moving them spatially, leaving space for screws secured to the ends of the drawer before screwing.

Znana predalčja za tako posebno nalogo niso primerna. Temu nasprotno pa kaže izum pot, da bi upoštevali tudi to dodatno nalogo in pri tem prišli do veznega elementa, ki dovoljuje tudi enostavno sestavljanje pri takih prostorskih predalčjih uporabljanih predalk, kar si v novejšem času prednostno prizadevajo.Known boxes are not suitable for such a specific task. On the contrary, the invention shows a way to take into account this additional task, and in doing so come up with a connecting element, which also allows easy assembly of used compartments of such spatial drawers, which in recent times have been a priority endeavor.

Rešitev te naloge po izumu poteka s pomočjo veznega elementa po značilnostnem delu patentnega zahtevka 1.The solution of this task according to the invention is by means of a connecting element according to the characteristic part of claim 1.

Na sliki 1 sta prikazani dve predalki 1 in 2, na katerih je pritrjen po en vozliščni kos 3 oz. 4. Tak vozliščni kos je lahko npr,, polovica ploščate šestkotne prizme, ki je na vsaki od treh manjših stranskih ploskev zasnovan s po eno navojno luknjo. Predalki 1 in 2 sta čvrsto vgrajeni v zgradbo, ki na sliki ni podrobneje podana, tako, da simetrijska os navojne luknje 5 vozliščnega kosa 3 in simetrijska os navojne luknje 6 vozliščnega kosa 4 ležita na eni premici.Figure 1 shows two compartments 1 and 2 on which one node piece 3 or 2 is attached. 4. Such a knot piece can be, for example, half of a flat hexagonal prism, which is formed by one threaded hole on each of the three smaller lateral surfaces. The compartments 1 and 2 are firmly integrated into the structure which is not shown in detail in such a way that the symmetrical axis of the threaded hole 5 of the knot 3 and the symmetrical axis of the threaded hole 6 of the knot 4 lie on one line.

Slika 1 kaže prav tako predalko 7, ki je na svojih koncih zasnovana s po enim veznim elementom 8 in 9 po izumu v odprtem stanju, kot tudi predalko 10, ki na svojih koncih obsega po en zaprt vezni element 11 in 12. Od veznih elementov 8, 9, 11, 12 je na sliki 1 vidna vsakokrat samo pokrivna tulka, iz katere v zaprtem stanju štrli po en vijak 13 oz. 14. V primerjavi s predalko dolžine L v odprtem stanju po izumu ima predalka 15 imenske dolžine L po stanju tehnike to pomanjkljivost, da je zaradi štrlečih vijakov 16 in 17 ni možno priviti v navojni luknji, brez da bi za montažo premestili predalki 1 in/ali 2 z njunega mesta, če je efektivna razdalja med čelnima stranema vozliščnih kosov 5 in 6 tudi enaka L.Figure 1 also shows a drawer 7 at its ends designed with one connecting element 8 and 9 according to the invention in the open state, as well as a drawer 10 comprising at its ends one closed connecting element 11 and 12. From the connecting elements 8, 9, 11, 12, in Fig. 1, only the cover sleeve is visible from which in each case one screw 13 or 10 is protruding in the closed state. 14. Compared to the open-length compartment L in the open state according to the invention, the compartment 15 of the nominal length L according to the state of the art has the disadvantage that due to the projecting screws 16 and 17, it is not possible to screw in the threaded hole without displacing the drawers 1 and / or 2 from their position, if the effective distance between the leading sides of node pieces 5 and 6 is also equal to L.

Predalka z veznima elementoma po izumu torej deluje na sledeč način:The drawers with connecting elements according to the invention therefore operate as follows:

Z vrtenjem pokrivnih tulk 11 in 12 v eni smeri okoli njunih simetrijskih osi se vrtita tudi vijaka 13 in 14, ki pa se hkrati osno premikata, dokler ne izgineta v notranjost pokrivnih tulk. V tem trenutku je skupna dolžina predalke 7 z dvema veznima elementoma 8 in 9 v odprtem stanju enaka L, tako da jo je brez nadaljnjega možno vstaviti med vozliščna kosa 5 in 6, in sicer tako, da je z vrtenjem pokrivnih tulk 8 in 9 vfdrugi smeri okoli njuneBy rotating the cover sleeves 11 and 12 in one direction around their symmetrical axes, the screws 13 and 14 are also rotated, but at the same time they move axially until they disappear inside the cover sleeves. At this point, the total length of the compartment 7 with the two connecting elements 8 and 9 in the open state is equal to L, so that it can be inserted without further interruption between the nodes 5 and 6 by rotating the cover sleeves 8 and 9 in the second directions around theirs

X simetrijske osi možno privitje vrtečih se in izhajajočih vijakov v navojni luknji 5 in 6. Odmontiranje se na najlažji način izvrši z vrtenjem pokrivnih tulk v smeri odpiranja.X symmetrical axes possible tightening of rotating and outgoing screws in threaded hole 5 and 6. Removal is easily done by rotating the cover sleeves in the direction of opening.

Na sliki 2 prikazan končni del predalke 20 obsega izvrtino 21, v'katero je s čelne strani krajevno čvrsto povezan navojni vložek 31, katerega Osna notranja izvrtina 23 obsega navoj. Povezava med navojnim vložkom 31 in predalko 20 je lahko npr. dosežena z lepljenjem ali privi jačenjem.In Fig. 2, the end portion of the compartment 20 comprises a bore 21, in which the threaded insert 31, whose axially inner bore 23, comprises a thread is locally connected to the front face. The connection between the threaded insert 31 and the drawer 20 may be e.g. achieved by bonding or bonding.

Na sliki 3 je podrobno prikazan navojni vložek 31, ki ne obsega samo notranji navoj preko celotne dolžine LE, temveč prednostno tudi zunanji navoj dolžine LA. En konec tega navojnega vložka je zasnovan kot šestroba glava 32.Figure 3 shows a threaded insert 31 detailing not only the inner thread over the entire length of the LE, but preferably also the outer thread of the length LA. One end of this threaded insert is designed as a hexagon head 32.

Slika 4 kaže navojni sornik 41 skupne dolžine LB, katerega del dolžine LH’ je zasnovan z navojem, del dolžine LE’ pa je gladek; tretji del dolžine Le ustreza glavi 42, katere premer je DC, pri čemer na razdalji. Lh < LH’ od konice navojni del obsega skoznjo izvrtino 43Slika 5 kaže šestrobo tulko 51 v obliki osno prevrtane šestkotne prizme dolžine LP, ki je zasnovana s stransko podolgovato odprtino 52 dolžine Lp in širine Ld. Na ustrezen način je z ozirom na vrtilno os simetrično glede na prvo odprtino lahko zasnovana druga, na sliki neprikazana, podolgovata odprtina.Figure 4 shows a threaded bolt 41 of total length LB, a portion of length LH 'of which is threaded and part of length LE' is smooth; the third part of length Le corresponds to head 42, whose diameter is DC, while at a distance. Lh <LH 'from the tip, the threaded portion extends through a bore 43Figure 5 shows a hexagonal sleeve 51 in the form of an axially drilled hexagonal prism of length LP, which is designed with a lateral elongate opening 52 of length Lp and width Ld. Suitably, with respect to the pivot axis, the second, non-illustrated, elongated aperture symmetrically relative to the first opening may be designed.

Na sliki 6 je prikazan prerez prečno na vzdolžno os pokrivne tulke 61, katere zunanji premer DA prednostno ustreza zunanjemu premeru predalke, njen notranji premer Da pa je nekoliko večji od zunanjega premera šestrobe tulke 51 Pri tem pokrivna tulka 61 na eni svoji strani - obsega konično zasnovan del 62, tako da je premer DA’ leve čelne ploskve nekoliko manjši od premera DA. Približno v sredini plaščne ploskve pokrivne tulke 61 je na voljo navojna luknja 63, v katero je možno priviti na sliki neprikazan navojni zatič, npr. navojni zatič z notranjim šestkotnikom, za čvrsto vpetje šestrobe tulke v notranjosti pokrivne tulke v vgrajenem stanju.Figure 6 shows a cross section transversely to the longitudinal axis of the cover sleeve 61, whose outer diameter DA corresponds preferably to the outer diameter of the drawer, and its inner diameter Yes is slightly larger than the outer diameter of the hexagon sleeve 51. designed part 62 so that the diameter DA 'of the left front face is slightly smaller than the diameter DA. Approximately in the center of the mantle surface of the cover sleeve 61 there is a threaded hole 63 into which it is possible to screw in the non-shown threaded pin, e.g. Threaded pin with inner hexagon for firmly securing the hexagon sleeve to the inside of the cover sleeve in its integrated state.

Elemente 41, 51 in 61 se vgradi kot sledi (slika 7,The elements 41, 51 and 61 are mounted as follows (Figure 7,

8) :8):

Navojni sornik 41, katerega zunanji premer DB navoja ustreza notranjemu premeru De navojnega vložka 31, sev notranjem prostoru 21 predalke 20 privije na navojni vložek 31 (slika 2), dokler njegov del dolžine LH’ ne pride skozi navojni vložek 31; v tem trenutku se lahko navojni sornik 41 znotraj navojnega vložka 31 prosto vrti, ker je dolžina LE’ nekoliko večja od dolžine LE in premer Db gladkega dela navojnega sornika nekoliko manjši od premera De.The threaded bolt 41, whose outer diameter DB of the thread corresponds to the inner diameter De of the threaded insert 31, screws the strain on the inner space 21 of the drawer 20 onto the threaded insert 31 (Figure 2) until a portion of length LH 'passes through the threaded insert 31; at this point, the threaded bolt 41 can rotate freely inside the threaded insert 31 because the length LE 'is slightly larger than the length LE and the diameter Db of the smooth portion of the threaded bolt is slightly smaller than the diameter De.

Nato se šestrobo tulko 51 namesti na štrleči del navojnega sornika 41, kar se lahko zgodi nemudoma, ker je zunanji premer DB navojnega sornika 41 manjši od notranje^ ga premera De šestrobe tulke 51, ki pri tem ne obsega nikakršnega navoja. V nadaljnjem koraku se spenjalni zatič cprosto vodi skozi odprtino 52 navojnega vložka 51 in Čvrsto vpne v izvrtino 43 navojnega sornika 41. S tem se doseže, da se šestroba tulka 51 in navojni sornik 41 lahko vrtita skupaj, vendar tako,da se, Čeprav se pri vrtilnem gibanju navojni sornik 41 istočasno premika tudi v osni smeri, šestroba tulka osno ne premakne, ker se spenjalni zatič pri vrtenju premika znotraj podolgovate odprtine 52. Za namene izuma tudi pokrivna tulka 61 ni neobhodno potrebna, vendar pa se jo lahko uporabi iz estetskih razlogov. Namesto šestrobe tulke je možno uporabiti tudi drugačno tulko. Tulčna glava 130, ki je prikazana na sliki 10, obsega izvrtino 131, v katero je možno s čelne strani npr. z lepljenjem ali varjenjem krajevno čvrsto povezati tulko 121 (slika 9), pri 'čemer osna notranja izvrtina tulke 121 prednostno ne obsega nikakršnega navoja. Tulka 121 in tulčna glava 130 tvorita tulčni vložek. Povezavo med tulčnim vložkom in predalko 10 (sl. 1) je možno doseči npr. z lepljenjem ali privijanjem.The hexagon sleeve 51 is then fitted to the projecting portion of the threaded bolt 41, which may occur immediately because the outer diameter of the DB of the threaded bolt 41 is smaller than the inside diameter De of the hexagonal sleeve 51, which does not comprise any thread. In a further step, the clamping pin is simply guided through the opening 52 of the threaded insert 51 and firmly clamped into the hole 43 of the threaded bolt 41. This achieves that the hexagon sleeves 51 and the threaded bolt 41 can rotate together, but so that, when rotating, the threaded bolt 41 also moves in the axial direction; the hexagon socket does not move axially because the clamping pin moves inside the elongated opening 52 when rotating. For the purposes of the invention, the covering sleeve 61 is not necessary, but can be used from aesthetic reasons. Instead of a hexagon sleeve, a different sleeve can also be used. The nozzle head 130 shown in FIG. 10 comprises a bore 131 into which it is possible from the front e.g. by gluing or welding, locally tighten the sleeve 121 (Fig. 9), wherein the axial inner bore of the sleeve 121 preferably does not comprise any thread. The sleeve 121 and the sleeve head 130 form a sleeve insert. The connection between the sleeve insert and the compartment 10 (Fig. 1) can be achieved e.g. by gluing or screwing.

Slika 11 kaže navojni sornik 141 skupne dolžineFigure 11 shows a threaded bolt 141 of total length

MB + Me, katerega del dolžine MH’ je zasnovan z navojem, del dolžine MB - MH’ pa je gladek; del dolžine Me ustreza glavi 142, katere premer je QG, pri čemer navojni del na razdalji Mh < -MH ’ od konice navojnega sornika obsega skoznjo izvrtino 143.MB + Me whose part length MH 'is threaded and part length MB - MH' is smooth; a portion of length Me corresponds to a head 142 whose diameter is QG, wherein the threaded portion at a distance Mh <-MH 'from the tip of the threaded bolt extends through a bore 143.

Slika 12 kaže šestrobo tulko 151 v obliki osno prevrtane šestkotne prizme dolžine MP, ki je zasnovana s stransko podolgovato odprtino 152 dolžine Mp in širine Md. Na ustrezen način je lahko z ozirom na vrtilno os simetrično glede na prvo odprtino zasnovana druga, na sliki neprikazana, podolgovata odprtina. Notranja izvrtina prizme je lahko okrogla ali npr. tudi šestroba (slika 12). Šestroba tulka 151 na čelni strani obsega spodnjo ploskev 153 z osno izvrtino s premerom Qp.12 shows a hexagonal sleeve 151 in the form of an axially inverted hexagonal prism of MP length, which is designed with a laterally elongated opening 152 of length Mp and width Md. Suitably, with respect to the rotary axis, the second, not shown, longitudinal opening may be symmetrical with respect to the first aperture. The inner bore of the prism may be circular or e.g. also hexagon (Fig. 12). The hexagon sleeve 151 on the front comprises a lower face 153 with a Qp diameter bore.

V sliki 13 je prikazan pogled od strani in v prerezu prečno na vzdolžno os vijačnega vložka 161 z navojnim delom 162, katerega zunanji premer ustreza zunanjemu premeru navojne luknje 5 predalke 1 (slika 1). Pri tem vijačni vložek 161 na eni svoji strani obsega šestrobo zasnovan del 163 z navojno izvrtino 164, v katero je možno priviti navoj ni sornik. Približno v sredini plaščne ploskve navojnega dela 161 je pravokotno na voljo navojna luknja 165, skozi katero je možno priviti na sliki 14 prikazan navojni zatič 171, npr. navojni zatič z notranjim šestkotnikom, za vodenje vijačnega vložka 161 v vgrajenem stanju.Figure 13 shows a side view and a cross-sectional view of the longitudinal axis of a screw insert 161 with a threaded portion 162, the outer diameter of which corresponds to the outer diameter of the threaded hole 5 of compartment 1 (Figure 1). The screw insert 161, on one side, comprises a hexagon-shaped part 163 with a threaded hole 164 into which the thread is not capable of being bolted. Approximately in the center of the mantle surface of the threaded portion 161, a threaded hole 165 is provided perpendicularly through which a threaded pin 171 can be screwed in Figure 14, e.g. Threaded pin with inner hexagon, for guiding screw insert 161 in the fitted state.

Elemente 141, 151 in 161 se montira kot Sledi (slika 14):The elements 141, 151 and 161 are mounted as follows (Figure 14):

Navojni sornik 141 , katerega zunanji premer QB navoja ustraza notranjemu premeru Qe vijačnega vložka 161, se v notranjosti predalke vodi skozi notranjo izvrtino tulčnega vložka 121, 130 (sliki 9 in 10), dokler njegov del dolžine MH’ ne pride skozi tulčni vložek, pri čemer se navojni sornik 141 znotraj tulčnega vložka lahko vedno prosto vrti, ker je notranji premer tulke 121 nekoliko večji od premera QB navojnega sornika.The threaded bolt 141, whose outer diameter QB of the thread corresponds to the inner diameter Qe of the screw insert 161, is guided through the inner bore of the sleeve 121, 130 (Figures 9 and 10), until a portion of length MH 'through the sleeve insert, at whereby the threaded bolt 141 inside the sleeve insert can always rotate freely because the inner diameter of the sleeve 121 is slightly larger than the diameter of the threaded bolt QB.

Nato se šestrobo tulko 151 s strani, ki je zasnovana z dnom, namesti na štrleči del navojnega sornika 141, kar se lahko zgodi nemudoma, ker je zunanji premer QB navojnega sornika 141 manjši od. notranjega premera spodnje izvrtine šestrobe tulke 151, ki pri tem ne obsega nikakršnega navoja. V nadaljnjem koraku se spiralno vzmet 172 (slika 14) prosto vodi preko navojnega sornika 141 in navojni sornik 141 privije v izvrtino 164 vijačnega vložka 161. S tem se .doseže, da se vijačni vložek 161 in navojni sornik 141 lahko skupaj vzmeteno osno premikata, vendar tako, da se, četudi se pri vrtilnem gibanju navojni sornik 141 istočasno lahko premika tudi v osni smeri, šestroba tulka 151 osno ne premika.Then, the hexagon sleeve 151 on the bottom side is mounted on the projecting portion of the threaded bolt 141, which may occur immediately because the outer diameter of the QB of the threaded bolt 141 is smaller than. the inner diameter of the lower bore of the hexagon sleeve 151, which does not comprise any thread. In a further step, the coil spring 172 (FIG. 14) is guided freely through the threaded bolt 141 and screwed the threaded bolt 141 into the bore 164 of the screw insert 161. It is thus achieved that the screw insert 161 and the threaded bolt 141 can be moved together by the spring axle. but in such a way that, even with the rotary movement, the threaded bolt 141 can simultaneously move in the axial direction, the hexagon sleeve 151 does not move axially.

Navojni sornik 141 (slika 14) bi bil lahko tudi po svoji delotni dolžini MB (slika 11) zasnovan z navojem.The threaded bolt 141 (Figure 14) could also be threaded in its entire length MB (Figure 11).

Vzmet 172 bi bila lahko tudi drugačna in/ali razporejena npr. izven notranjosti vodilne tiilke. Notranja izvrtina tulke 31, 121 in 221 je lahko tudi gladka.Spring 172 could also be different and / or arranged e.g. outside the inside of the guide tilka. The inner bore of the sleeve 31, 121 and 221 may also be smooth.

V primeru po slikah 12 in 13 navojni zatič 171 lahko odpade. Vozliščni kos po sliki 1 je, razumljivo, lahko zasnovan tudi kroglasto.In the case of Figures 12 and 13, the threaded pin 171 may fall off. The node piece of Figure 1 can, of course, also be spherical in design.

Vozliščni kos, ki je npr. prikazan na sliki 15, obsega kroglasto zasnovo z več ploskovnimi mesti 201, 202, ..., ki so zasnovana s po eno navojno luknjo, v katero je vsakokrat možno priviti cevno palico, da bi s pomočjo več cevnih palic in vozliščnih kosov lahko uredili predalčje.A node piece that is e.g. shown in Fig. 15 comprises a spherical design with several planes 201, 202, ..., which are designed with a single threaded hole, into which the pipe rod can be screwed at each time, so that several pipe rods and hub pieces can be arranged too far.

Na sliki 16 prikazana cevna palica ima okrogel prerez in je zasnovana z vzdolžnimi utori 211, 212, ... . Take cevne palice, ki so lahko tudi pravokotne, so znane npr. izThe tubular bar shown in Figure 16 has a circular cross section and is designed with longitudinal grooves 211, 212, .... Such pipe rods, which may also be rectangular, are known e.g. from

CH-PS-588 233.CH-PS-588 233.

Na sliki 17 prikazani vezni element namesto vijači nega vložka 161 po sliki 13 obsega enostavnejši vodilni vložek 261.In Fig. 17, the connecting element shown in place of the screw insert 161 according to Fig. 13 comprises a simpler guide insert 261.

Predalka (slika 1) z veznima elementoma po slikah 9 do 17 deluje na sledeč način:The drawer (Fig. 1) with connecting elements according to Figures 9 to 17 operates as follows:

Vijaka 13 in 14 sta vzmeteno uležiščena in se lahko z blagim pritiskom osno premikata, dokler ne izgineta v notranjosti pokrivne tulke. V tem trenutku je skupna dolžina predalke 7 z dvema veznima elementoma 8 in 9 v odprtem stanju enaka L, tako da jo je brez nadaljnjega možno vstaviti med vozliščna kosa 3 in 4, in sicer tako, da je z vrtenjem pokrivnih tulk 8 in 9 v primerni smeri okoli njune simetrijske osi možno privitje vrtečih se in izhajajočih vijakov v navojni luknji 5 in 6. Odraontiranje se na enostaven način izvrti z vrtenjem pokrivnih tulk v smeri odpiranja.The bolts 13 and 14 are spring-loaded and can be moved axially with gentle pressure until they disappear inside the cover sleeve.

Vodilno tulko po sliki 20,ali enostavneje tako s samo eno podaljšano odprtino,je možno uporabiti namesto elementov 51 (slike 5, 7, 8), 151 (sliki 12, 14), 181 (slika 18) in 197 (slika 19), pri čemer vodilna tulka lahko obsega na sliki 20 neprikazano spodnjo ploskev kot spodnjo ploskev 153 tulke 151 (slika 12).The guide sleeve of Fig. 20 consists of a tubular and laterally elongated opening 222 of the shaped body 221, wherein the ends of the opening 222 are each extended in the opposite direction at right angles to the rotary axis of the tubular body 221, preferably one of the extended openings 223 comprises a circular and the other of extended openings semicircular extension. The guide sleeve of Fig. 20, or more simply with only one extended opening, can be used instead of elements 51 (Figures 5, 7, 8), 151 (Figures 12, 14), 181 (Fig. 18) and 197 (Fig. 19). wherein the guide sleeve may comprise, in Figure 20, a non-shown lower face than the lower face 153 of the sleeve 151 (Figure 12).

Pri cevasti vodilni tulki 225 po sliki 21 je en konec 227 podolgovate odprtine 226 glede na vrtilno os tulke odklonjen za kot w, pri čemer kot w lahko zavzame poljubno vrednost med 0 in 90°.In the tubular guide sleeve 225 of FIG. 21, one end 227 of the elongated opening 226 with respect to the rotation axis of the sleeve is deflected by an angle w, where the angle w may take any value between 0 and 90 °.

Cevasta vodilna tulka 227 po sliki 22 obsega krivuljno ali S-oblikovano odprtino 228, vodilna tulka 229 po sliki 23 pa poševno potekajočo podolgovato odprtino 230, katerih en konec je lahko zasnovan z zakrivljenim podalj-L škom 231. Tudi vodilne tulke po slikah 21 do 23 je možno uporabiti namesto elementov 51, 151, 181 in 197, pri čemer bi v takem primeru lahko odpadla vzmet 172 in spodnja plo'Z -5> kev 153 (slika 14), ker se pri vrtenju vodilne tulke 225, 227 ali 229 zatič, ki je všbavljen v odprtino 226’, 228’ oz. 230, samodejno premakne naprej, kar olajša privitje navojnega sornika v navojno luknjo vozliščnega kosa.The tubular guide sleeve 227 of Fig. 22 comprises a curved or S-shaped opening 228, and the guide sleeve 229 of Fig. 23 an oblique extending opening 230, one end of which may be formed by a curved extension L 231. Also, the guide sleeves of Figures 21 to 23 can be used instead of elements 51, 151, 181 and 197, in which case the spring 172 and the lower plate 5Z> 153 may be dropped (Fig. 14), since the guide sleeve 225, 227 or 229 rotates a pin that is threaded into the opening 226 ', 228' or. 230, automatically moves forward, making it easier to screw the threaded bolt into the threaded hole of the hub.

Ojačena tulka po sliki 24 obsega cevasto vodilno tulko 241 npr. po slikah 20 do 23, in sicer v danem primeru tudi brez sicer predvidenih krožnih, polkrožnih ali zakrivljenih podaljškov 223, 224 in 231 (sliki 20, 23). Vodilna tulka2241 je vstavljena v notranjost ojačevalne tulke 242, in sicer tako, da zunanji premer vodilne tulke 241 ustreza znotranjemu premeru ojačevalne tulke 242. Povezavo med tulko 242 in tulko 241 je možno doseči s privijanjem, lepljenjem, vtiskanjem ipd'.!. V danem primeru je relativno premikanje med obema tulkama možno preprečiti z vijakom 243. Tulka 242 lahko obsega okroglo ali transverzalno podaljšano odprtino 244, skozi katero je dostopen vodilni zatič 245 navojnega sornika 246.The reinforced sleeve of Figure 24 comprises a tubular guide sleeve 241 e.g. 20 to 23, even if not provided with circular, semicircular or curved extensions 223, 224 and 231 (Figures 20, 23). Guide sleeve2241 is inserted inside the reinforcement sleeve 242, such that the outer diameter of the guide sleeve 241 corresponds to the inside diameter of the reinforcing sleeve 242. The connection between the sleeve 242 and the sleeve 241 can be achieved by screwing, gluing, stamping, etc. ' In the present case, relative movement between the two sleeves can be prevented by screw 243. The sleeve 242 may comprise a round or transversally extended opening 244 through which a guide pin 245 of the threaded bolt 246 is accessible.

Tulka 241 in tulka 242 lahko v vgrajenem stanju obsegata skupno izvrtino 247, skozi katero je možno v navojni sornik 246 priviti zapahnilni vijak.The sleeve 241 and the sleeve 242 may comprise in a built-in condition a common bore 247 through which a locking screw can be screwed into the threaded bolt 246.

Delovanje veznega elementa s tulko po eni od slik do 24 je enako kot pri že opisanih veznih elementih. Razlika je v tem, da se sila, ki je potrebna za privijanje navojnega sornika 246 v vozliščni kos, prenaša preko zatiča 245, ki mora biti temu primerno dimenzioniran. Zatič 171 po sliki 14 torej aiuži za držanje navojnega sornika 141 s prsti,prednostno s palcem,v želenem položaju.The operation of the connecting element with the sleeve according to one of the figures up to 24 is the same as that of the previously described connecting elements. The difference is that the force required to tighten the threaded bolt 246 into the hub piece is transmitted through pin 245, which must be dimensioned accordingly. The pin 171 of FIG. 14 is therefore a lever for holding the threaded pin 141 with the fingers, preferably with the thumb, in the desired position.

Predalki po slikah 25 in 26 obsegata vzdolžne zajede 251, 252 oz. 261, 262, kamor z lahnim osnim vrtenjem predalke vstavljivi robovi ostenja. Nasprotno temu pa je na sliki 27 prikazana enostavna viljasta predalka 270.The drawers according to Figures 25 and 26 comprise longitudinal engagements 251, 252 and. 261, 262, by which the edges of the wall can be inserted by lightly rotating the drawer. In contrast, Figure 27 shows a simple fork-shaped compartment 270.
