Kendte transportvogne af denne art er ved omtrent midten forsynet med to transporthjul, samt ved hver ende med en møbelrulle, idet vognen under bevægelse bæres af transporthjulene og den ene møbelrulle, medens den anden møbelrulle er løftet fri af gulvet. Dette gør det muligt at passere dørtrin eller andre forhindringer på gulvet. Ved passage af en sådan forhindring føres den forreste, hævede møbelrulle over denne, hvorefter vognen vippes fremad, således at den hviler på den forreste møbelrulle og transporthjulene, hvorefter vognen let føres over forhindringen.Known transport vehicles of this kind are provided at approximately the middle with two transport wheels, as well as at each end with a furniture roller, the moving carriage being carried by the transport wheels and one furniture roller, while the other furniture roller is lifted off the floor. This makes it possible to pass doorsteps or other obstacles on the floor. When passing such an obstacle, the front raised roll of furniture is passed over it, after which the carriage is tilted forward so that it rests on the front furniture roll and the transport wheels, after which the carriage is easily moved over the obstacle.
De pladeformede materialers næsten lodrette placering gør det vanskeligt at afmærke og udskære dele af en plade.The almost vertical placement of the sheet material makes it difficult to mark and cut parts of a sheet.
Denne ulempe er undgået ved en anden type af kendte transportvogne, som understøttes af fire ens hjul eller møbelruller, og hvor det pladerne bærende stillads eller bord kan vippes ned og danne en i det væsentlige vandret arbejdsflade. Sådanne vogne er imidlertid vanskelige at manøvrere over eksempelvis dørtrin.This disadvantage is avoided by another type of known transport carriage, which is supported by four identical wheels or rollers of furniture, and where the scaffolding or table-bearing plates can be tilted down to form a substantially horizontal working surface. However, such wagons are difficult to maneuver over, for example, door steps.
Den foreliggende opfindelse angår således transportvogne"med en langstrakt, rektangulær ramme, som har en møbelrulle i hvert hjørne og to omtrent ved rammens midte^ anbragte »hævelige og sænkelige transporthjul samt en til rammen fastgjort opstående konsol, i hvilken i brugsstillingen af vognen et om en langsgående akse mellem en med lodret svagt skrånende stilling og en i det væsentlige vandret stilling svingbart bord er ophængt.The present invention thus relates to transport vehicles "having an elongated, rectangular frame having a piece of furniture in each corner and two approximately" upright and lowerable transport wheels "and a raised bracket mounted to the frame, in which in the position of use of the carriage a a longitudinal axis between a vertically slightly inclined position and a substantially horizontal position pivot table is suspended.
Det er ifølge opfindelsen fordelagtigt, at vognen har organer til at forbinde bordet med en svingningsmekanisme ved transporthjulene, hvilke organer er således indrettet, at transporthjulene hæves fra underlaget, når bordet føres til i det væsentlige vandret stillung. Ved at udforme transportvognen på denne måde undgår man de ovenfor nævnte ulemper ved de kendte vogne.According to the invention, it is advantageous for the carriage to have means for connecting the table with a pivot mechanism at the transport wheels, which means are arranged so that the transport wheels are raised from the ground when the table is brought to a substantially horizontal position. By designing the transport trolley in this way, the above-mentioned disadvantages of the known carriages are avoided.
Ifølge opfindelsen kan organerne til frembringelse af transporthjulenes op- og nedadgående bevægelse hensigtsmæssigt bestå af en til bordet fastgjort, med dette svingningsakse koncentrisk, halvcirkelformet plade, en mellem denne og hjulophængningen anbragt stang, to af en passende vinkel adskilte udskæringer i pladens kantparti samt en til konsollen fastgjort spærremekanisme til samvirke med disse udskæringer.According to the invention, the means for producing the upward and downward movement of the transport wheels may conveniently consist of a plate, arranged with this pivotal axis concentric, semi-circular plate, a rod disposed therebetween and the wheel suspension, two cuts at an appropriate angle in the edge portion of the plate and the bracket attached locking mechanism to cooperate with these cuts.
144586 - 3 -144586 - 3 -
For at komme frem til en vis arbejdsposition kan man have behov for at flytte vognen alene på møbelrullerne, men med bordet stående oprejst. Det er herfor ifølge opfindelsen fordelagtigt, at de organer, som forbinder bordet med svihgningsmekanismen ved transporthjulene, består af en stang med indbyrdes teleskopisk forskydelige dele, som dels af en fjeder er belastet i den delene sammenførende retning, dels er forsynet med et organ, som kan holde delene fikseret i indbyrdes udtrukne stillinger.To arrive at a certain working position, you may need to move the carriage alone on the furniture rollers, but with the table upright. Accordingly, it is advantageous according to the invention that the means which connect the table to the swinging mechanism at the transport wheels consist of a rod having telescopically displaceable parts, which are partly loaded by a spring in the connecting part, and partly provided with a means which can keep the parts fixed in mutually extended positions.
Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor fig. 1 viser en transportvogn ifølge opfindelsen i perspektiv, fig. 2 samme set fra siden, og fig. 3 et tværsnit gennem en modificeret udformning af vognen.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail in connection with the drawing, in which: FIG. 1 is a perspective view of a transport vehicle according to the invention; FIG. 2 is a side view, and FIG. 3 is a cross-section through a modified configuration of the carriage.
Den viste transportvogn omfatter en langstrakt, rektangulær ramme 10, som i hvert hjørne understøttes af en møbel-rulle forsynet med et par transporthjul 15,16 på en tværgående aksel omtrent midt på rammen.The shown carriage comprises an elongated, rectangular frame 10 supported in each corner by a furniture roller provided with a pair of transport wheels 15,16 on a transverse shaft approximately in the middle of the frame.
Transporthjulene 15,16 er monteret på svingbare arme 17, således at de kan fastholdes i en rammen bærende stilling, hvor vognen er let at bevæge, eller hæves, således at rammen alene hviler på møbelrullerne 11-14 og derved understøttes stabilt.The transport wheels 15,16 are mounted on pivotable arms 17 so that they can be held in a frame-bearing position where the carriage is easy to move, or raised, so that the frame rests solely on the furniture rollers 11-14 and is thereby stably supported.
Et par af møbelrullerne kan forsynes med en bremsemeka-nisme, således at vognen kan holdes stille.A pair of the furniture rollers may be provided with a braking mechanism so that the carriage can be kept still.
Rammen 10 bærer en konsol bestående af tre, som ligebenede trekanter udformede bukke 18, der foroven bærer lejer 19 for et svingbart bord 20.The frame 10 carries a bracket consisting of three, like straight triangles, shaped bucks 18 which carry bearings 19 above for a pivotable table 20.
Bordet 20 er opbygget som et åbent gitter med langs- og tværgående stænger og er ved sin ene langsgående kant forsynet med en hylde 21, på hvilken pladeformede materialer hviler Vinder transport. Gitteret gøres så langt, som det er hensigtsmæssigt af hensyn til manøvrerbarheden under transport af de største plader, som skal håndteres. De tværgående stænger i gitteret kan udgøres af teleskopisk samvirkende dele, således at bordets bredde kan varieres efter behov, idet de samvirkende dele kan sammenlåses i forskellige ind- 144586 - 4 - byrdes stillinger ved hjælp af låsesplitter eller på anden passende måde.The table 20 is constructed as an open grid with longitudinal and transverse rods and is provided at its one longitudinal edge with a shelf 21 on which plate-shaped materials rest Winner transport. The grating is made as far as is appropriate for the maneuverability during transport of the largest plates to be handled. The transverse bars of the grid may be telescopically cooperating members so that the width of the table may be varied as required, the interacting members being interlocked in various positions of positions by means of locking splits or by any other suitable means.
Rammens langsider kan hensigtsmæssigt udgøres af rør, som forbindes til gitterets tværgående stænger på en sådan måde, at rørenderne er frit tilgængelige. Man kan da efter behov indføre forlængelsesstænger i rørene for at kunne transportere særligt lange genstande.Conveniently, the longitudinal sides of the frame may be constituted by pipes which are connected to the transverse bars of the grid in such a way that the pipe ends are freely accessible. Extension bars can then be inserted into the pipes as needed to carry particularly long objects.
Bordet er på sin vinderside forsynet med ører 22, som er lejret i konsollen 18, og bordet kan svinges på den i fig. 1 viste skrå transportstilling til den i fig. 3 viste vandrette arbejdsstilling.The table is provided on its winding side with ears 22 which are mounted in the bracket 18 and the table can be swiveled on the one shown in FIG. 1 shows the inclined transport position shown in FIG. 3 shows the horizontal working position.
I bordets i forhold til lodret svagt skrånende transportstilling udgør vognen med de pladeformede legemer en forholdsvis smal transportenhed, som kan manøvreres gennem trange passager, og når bordet er vandret, udgør det en hensigtsmæssig arbejdsflade for afmærkning og udskæring af de på bordet liggende plader.In the table relative to the vertically slightly sloping transport position, the carriage with the plate-shaped bodies constitutes a relatively narrow transport unit which can be maneuvered through narrow passages, and when the table is horizontal it constitutes an appropriate working surface for marking and cutting the plates lying on the table.
Fig. 2 anskueliggør, hvorledes vognen kan fremføres med transporthjulene 15,16 og det ene, her bageste, sæt møbelruller 13,14 hvilende på gulvet. De forreste møbelruller 11,12 kan let føres over eksempelvis et dørtrin 30 eller en anden forhindring på gulvet. Derefter vippes vognen fremad, således at vognen nu hviler på hjulene 15,16 og de forreste ruller 11,12. På grund af transporthjulenes større diameter kan disse let passere forhindringen 30.FIG. 2 illustrates how the carriage can be conveyed with the transport wheels 15,16 and the one, at the rear, set of furniture rolls 13,14 resting on the floor. The front furniture rollers 11,12 can be easily moved over, for example, a door step 30 or another obstruction on the floor. Then the carriage is tilted forward so that the carriage now rests on the wheels 15,16 and the front rollers 11,12. Due to the larger diameter of the transport wheels, these can easily pass the obstacle 30.
Når bordet anvendes som arbejdsflade i vandret stilling, er det væsentligt, at rammen 10 hviler stabilt. Herfor hæves transporthjulene 15,16, således at rammen alene bæres af møbelrullerne 11-14.When the table is used as a work surface in a horizontal position, it is essential that the frame 10 rests stable. For this purpose, the transport wheels 15,16 are raised, so that the frame alone is supported by the furniture rollers 11-14.
Manøvrering af transporthjulene 15,16 sker automatisk i forbindelse med svingning af bordet 20. D'e'tte er på sin underside ved den midterste af konsolbukkene 18 forsynet med en halvcirkelformet plade 23, der via en stang 24 er forbundet med den hjulaksel 25, som bærer hjulene 15»16 i de svingbare arme 17. Stangen 24 holder transporthjulene 15,16 i bærende stilling, når bordet 20 står i skrå transportstilling, men løfter hjulene fra kontakt med underlaget, når bordet svinger til vandret arbejdsstilling.The transport wheels 15,16 are actuated automatically in connection with pivoting of the table 20. On its underside, at the middle of the bracket bends 18, is provided with a semicircular plate 23 which is connected via a rod 24 to the wheel shaft 25. which carries the wheels 15 »16 in the pivotal arms 17. The rod 24 holds the transport wheels 15,16 in the supporting position when the table 20 is in an inclined transport position, but lifts the wheels from contact with the support as the table swings to a horizontal working position.

For at muliggøre fiksering af bordet 20 i de to yderstillinger er pladen 23 forsynet med to kantudskæringer 26 og 27 i en indbyrdes vinkelafstand svarende til bordets svingbevægelse. Med disse udskæringer 26,27 samvirker en fjederbelastet spærremekanisme 28, der kan frigøres ved hjælp af et organ 29.In order to enable fixing of the table 20 in the two outer positions, the plate 23 is provided with two edge cuts 26 and 27 at an angular distance corresponding to the swinging motion of the table. With these cuts 26,27 cooperate a spring-loaded locking mechanism 28 which can be released by means 29.
I snævre passager eller ved bevægelse af vognen til siden kan det være hensigtsmæssigt, at vognen kan bevæges alene på møbelrullerne, selv om bordet 20 befinder sig i den skrå transportstilling. Herfor kan stangen 24, som det er vist i fig.In narrow passages or when moving the carriage to the side, it may be convenient for the carriage to move on the furniture rollers alone, even if the table 20 is in the inclined transport position. For this, rod 24, as shown in FIG.
3, udgøres af to teleskopisk samvirkende dele 24a,24b, som i sammenskydende retning er belastet af en fjeder 30.3, is constituted by two telescopically cooperating portions 24a, 24b, which are loaded together in a reciprocating direction by a spring 30.
Et spærreorgan 31 i form af en stift, som kan føres gennem huller i de to dele 24a,24b forhindrer normalt sammen-skydning af delene, og disse udgør da en stor stang. Spærreorganet 31 er ved hjælp af en kæde 32 fastgjort til stangen eller en anden passende del af vognen.A locking member 31 in the form of a pin which can be passed through holes in the two parts 24a, 24b normally prevents the parts from interconnecting, and these then constitute a large rod. The locking member 31 is secured to the rod or other suitable part of the carriage by means of a chain 32.
Trækkes stiften 31 ud af hullerne, vil fjederen 30 skyde delene 24a,24b sammen. Ved denne afkortning af stangen 24 løftes armene 17, således at hjulene 15,16 løftes fri af underlaget.If the pin 31 is pulled out of the holes, the spring 30 will push the parts 24a, 24b together. In this shortening of the rod 24, the arms 17 are lifted so that the wheels 15,16 are lifted free of the support.
Når man atter vil benytte transporthjulene, træder man på dem eller låser dem fast på anden måde og løfter vognens ene ende, eller man vipper bordet 20 til vandret stilling, hvorefter spærreorganet 31 genindsættes i hullerne.When you want to use the transport wheels again, you step on them or lock them in another way and lift one end of the carriage, or tilt the table 20 to a horizontal position, after which the locking means 31 is reinserted into the holes.
Pladen 23 kan forsynes med flere end de to viste udskæringer 26 og 27, således at bordet 20 kan fikseres i andre stillinger. Eksempelvis kan det være hensigtsmæssigt, at bordet kan føres forbi den vandrette stilling, således at plader let kan trækkes af fra bordet ved dettes fra hylden 21 vendte kant. Forbindelsen mellem stangen 24 og skiven 23 henholdsvis akselen 25 kan derved udføres med en vis frigang.The plate 23 can be provided with more than the two cutouts 26 and 27, so that the table 20 can be fixed in other positions. For example, it may be convenient for the table to be moved past the horizontal position so that plates can be easily pulled off the table at its edge facing away from the shelf 21. The connection between the rod 24 and the disc 23 or the shaft 25 can thereby be made with a certain clearance.
