Definitions

  • the invention relates to a wheel trolley according to the preamble of claim 1.
  • Known wheel trolleys of this type are based on the principle of flat contact between the various contacting surfaces with the running surface of the tyre to be supported, possibly including partial enclosing of the sides of the tyre adjacent the undercarriage, while the inclined support surface and the drive-on ramp are provided with a catch mechanism so as to maintain an inclined position adapted to the dimensions of the tyre.
  • the undercarriage may be provided with a hinge to enable the folding of the trolley, in order to reduce the dimensions for storage.
  • the dimensions of the wheel trolley may, in the storage position, be reduced to a minimum by folding back the drive-on ramp against the floor of the wheel trolley, while the securing means ensure that the vehicle wheel will not leave the trolley during driving on as a result of the driving and/or reaction forces.
  • Figs. 1A and IB a schematic side elevation and a planview from below, respectively, of an embodiment of the wheel trolley according to the present invention in the operative position;
  • FIG. 2 and 3 side elevation views, corresponding to Fig. 1A, of the wheel trolley in the drive-on position and the storage position, respectively;
  • Fig. 4 a partial side elevation view of a wheel trolley with a modified drive-on ramp, in which the drive-on ramp is shown in the operative position and the folded position, respectively, by dashed lines;
  • Fig. ' 5 a plan view of the wheel trolley according to Fig. 4 in the operative position with modified securing means for a vehicle wheel.
  • the wheel trolley shown in the drawing comprises an undercarriage 1 with a plate-shaped floor 2 and upstanding sidewalls 3, the distance between which is adapted to the width of a tyre to be supported, in particular a deflated tyre which bulges out to some extent.
  • supports 5 are provided which serve to support an axle 6 for a first running wheel 7.
  • a second axle 10 for second running wheels 11 is supported by supports 9.
  • a drive-on ramp is articulated, through the intermediary of transverse supports 13, around an axis 14, which is displaced towards the first end 4 relative to the running wheel axle 10.
  • the portion 15 thereof which is located on the drive-on side has upstanding flanges 16, while on the other side of the axis 14 a somewhat curved portion 17 adjoins it, the end of which, in the position shown in Fig. 1, abuts the floor 2. In the drive-on position of Fig. 2, this portion 17 is situated at the upper side.
  • the axis 14 is situated in such a way that the ramp 12 will only turn over after the wheel to be supported has passed the axle 10 of the running wheels 11.
  • the ramp 12 has an outer edge 18 which, in the position shown in Fig. 2, rests on the road surface 19.
  • the floor 2 is adjoined by a support surface 20 which, preferably, has a curvature corresponding to the curvature of a tyre or wheel rim.
  • a support surface 20 which, preferably, has a curvature corresponding to the curvature of a tyre or wheel rim.
  • the drive-on ramp 12 is turned over in such a way that the slanted terminal edge 18 rests on the road surface 19. A vehicle wheel may then be driven onto the trolley until the tyre contacts the support surfcace 20.
  • the transverse supports 13 are further provided with transversely extending spurs 21, which, in the position of
  • Fig. 2 rest on the road surface 19 and, then, act as a brake for the wheel trolley. Thereby the wheels 11 may be slightly lifted off the road surface.
  • a U-shaped bracket 22 with legs 23 and a connecting piece 24 is provided. More particularly, this connecting piece, as shown, may be made somewhat converging in order to ensure a good grip on the tyre, and to provide, in particular, an adaptation to various tyre sizes.
  • the ends 25 of the legs 23 each engage an eye 26 made in a side wall 3 so as to form hinge connection.
  • This bracket is further provided with downwardly directed supports 27, each of which extends through an adapted aperture 28 at the front end 4, and is provided, at its free end, with a locking hook 29 which may engage the edge of the opening 28 in question to maintain the bracket 22 in the upward position of Fig. 1.
  • the ends of the legs 23 may each be provided with a spring 30, these springs pressing the brackets 22 forward and thereby supporting the locking by the ends 29. This, by the way, may also be achieved by making the supports 27 resilient. Of course, other locking means may be used as well.
  • the length of the supports 27 is preferably such that in the operative position of Fig. 1 the bracket is located at least at the level of the axis of the supported wheel in order to improve the transfer of forces.
  • Fig. 3 the storage position of the wheel trolley is shown. In this position, the drive-on ramp 12 is folded down, and is, at least approximately, in contact with the floor 2 of the undercarriage 1. Thus, the dimensions of the wheel trolley may be significantly reduced.
  • the distance between the axles 6 and 10 is chosen so large that the torques which are exerted by a driven wheel are counteracted so as to prevent dragging of the trolley by the wheel.
  • the front side 20 of the floor 2 is preferably curved in such a way that an adaptation to the curvature of the supported tyre is achieved.
  • a further advantage thereof is that irregularities which may be present in the road surface 19, as well stones or suchlike lying thereon, easily slide away underneath the trolley.
  • This curvature and the distacne between the side walls 3 and the flanges 16 may further be adapted to specific wheel and tyre sizes.
  • the tyre to be supported will usually be deflated, it will usually jam itself sufficiently tight, so that, with a limited number of wheel trolley sizes, all common passenger vehicles may be served.
  • the flanges 16 of the drive-on ramp provide centering of the wheel during driving on. This, as well as securing of the wheel, may be achieved by providing centrally in the drive-on ramp, and possibly also in the support surface 20, a raised portion with a U-shaped cross-section around which the deflated tyre will bulge. In the case of asymmetrical wheel rims or stiff tyres (e.g. steel-belted tyres) this may, however, lead to insufficient centering.
  • a recess (not shown) in the floor or the drive-on ramp 12 at the or each running wheel 11, through which the upper side of the wheel in question may project in the drive-on position, whereas, if the ramp is turned upwards, the running wheel is screened off by the ramp 12 due to the displaced position of the articulation axis 14 relative to the wheel axle 10.
  • the vehicle wheel will then contact the or each running wheel 11 and rotate it backwards, so that the trolley will, then, automatically be pulled underneath the wheel.
  • the drive-on ramp portions 15 and 17 may be provided with slightly projecting ribs or the like (see Figs. 4 and 5) , improving the grip on the tyre.
  • Figs. 4 and 5 show a modified embodiment of a drive-on ramp 12, in which the actual drive-on portion 15' and an actuating portion 17', which serves to turn over the ramp, are hingedly connected to each other, and in which the axle 10 of the running wheels 11 provides the tilting axis of the ramp 12 as well as the hinge axis between said portions.
  • the drive-on portion 15' and the actuating portion 17' are again provided with supports 13' and 13" with which these portions are supported on the axle 10.
  • the drive-on portion 15' may be further rotated towards the floor 2, as indicated in Fig. 4. It is possible, by the way, to articulate the drive-on ramp in the way shown in Fig. 1 around another axis than the axle 10 if desired.
  • the side surfaces 16' extend downwards, achieving a good braking contact with the road surface 19, while, as shown, the running wheels 11 are lifted from the road surface 19.
  • the length of the portion 15' may be chosen so small that, in the operative position, it does not contact any undercarriage portion of the vehicle, while, however, the inclination in the drive-on position is sufficiently small to avoid the trolley being pushed forward during driving on by the vehicle.
  • Figs. 4 and 5 show, at 32, the aforesaid ribs which improve the grip on the tyre. It further follows from Fig. 4 that, in the operative and in the folded position, the wheels 11 rest on the surface 19.
  • FIG. 6 shows a simplified representation of a wheel trolley with yet a different way of securing a vehicle wheel 33, in which the drive-on ramp 12 is indicated schematically.
  • a carbine hook 35 is articulated, which may be hooked into a chain 36, the other end of which is provided with a hook 37 which may be hooked into a hole 38 in the wheel 33.

Abstract

Un chariot destiné à porter la roue d'un véhicule, notamment une roue dont le pneu est dégonflé, comporte un train à roues de roulement, une première surface de support pour le pneu de la roue, située à une première extrémité du train, et une rampe d'accès reliée par charnières à la seconde extrémité du train. Lorsque la roue devant être portée passe l'axe des charnières, ladite rampe se retourne afin de servir ensuite de deuxième surface de support pour la roue. Des moyens (20, 22, 36) servent à immobiliser la roue du véhicule sur le chariot, et la rampe (12) se replie contre le train (1) du chariot en l'absence d'une roue. Ladite rampe (12) est constituée de deux parties (15', 17') connectées l'une à l'autre par des charnières. Les moyens d'immobilisation peuvent comporter un archet en forme de ''U'' (22) qui est relié au train (1) par des charnières et qui, en position soulevée, entre en contact avec le pneu de la roue. Lesdits moyens peuvent également comporter au moins une chaîne ou attache (36) dont la longueur est réglable et qui est munie, à une extrémité, d'un crochet (37) destiné à s'engager dans une ouverture (38) ménagée dans l'enjoliveur (33) de la roue du véhicule.
