Definitions

  • THIS INVENTION relates to elevating apparatus, and it has particular but not exclusive reference to such apparatus for raising and lowering articles to and from a rigid support platform, such as the moving of a wheelchair into and out of a van-type vehicle.
  • my invention resides broadly in elevating apparatus including first carriage means and second carriage means, track means adapted to support said first carriage means and adapted to be mounted on a platform for horizontal movement of said first carriage means from a stored position on the platform remote from its free edge to an upper loading position overlapping said free edge, said second carriage means being supported operatively by said first carriage means and mounted for vertical movement relative thereto when said first carriage means is in said upper loading position, whereby said second carriage means is transferable from said upper loading position to a lower loading position at or adjacent the ground or other base level means.
  • the horizontal track means may include a pair of spaced parallel tracks extending between said stored and upper loading positions, said first carriage means being mounted on guide rollers or equivalent means engaging said parallel tracks in guided relationship thereto. It is preferred that the tracks be secured to a motor vehicle van floor for loading and unloading through a door thereof, such as the rear door of a van, such rear door being of a height to accommodate a loaded wheelchair for example, the latter being accommodated within the van in stored attitude when the first carriage means occupies the innermost or stored position.
  • the second carriage means be mounted so that it can travel vertically relative to the first carriage means between upper and lower loading positions when the carriage means is furthermost from the stored position, guide means being associated with the first carriage means to co-operate with rollers or other guide means on upstanding frame members of said second carriage means.
  • guide means being associated with the first carriage means to co-operate with rollers or other guide means on upstanding frame members of said second carriage means.
  • the said upstanding frame members of said second carriage means are raisable in guided manner relative to upper guide channel members which are themselves raisable in guided manner relative to and within fixed channel assemblies on said first carriage means, power means being provided for lifting the guide channel members and their supported lower upstanding frame members in a two-stage telescopic-type action enabling the fixed channel assemblies on the first carriage means to be made to a height not substantially exceeding the designed lifting height of the said upstanding frame members.
  • the second carriage means of the elevating apparatus When used for wheelchair transport, the second carriage means of the elevating apparatus will have its upstanding frame members connected at their lower extremities to a horizontal floor plate assembly adapted to support the wheelchair to be lifted. It is preferred that the floor plate assembly be provided with an entry gate adapted to be lowered to permit the wheelchair to be driven thereon or raised to prevent accidental removal therefrom, said gate being mounted for pivotal movement about a horizontal axis between lower and raised positions by lever means adapted to be locked by over-centre toggle means when the gate is raised.
  • the floor plate may suitably be provided also with an adjustable safety gate towards its front remote from the entry gate.
  • a disabled person in a wheelchair may drive onto the floor plate, whereafter the wheelchair may be secured in position, and then the second carriage means may be raised by electric power relative to the first carriage means until they are both in the extended upper loading position, whereafter both carriage means can be moved slidably in unison to take the wheelchair to its stored position.
  • Fig. 1 is a perspective view of the rear of a motor vehicle van fitted with elevating apparatus according to the invention and shown in lowermost loading position;
  • Fig. 2 is a perspective view similar to Fig. 1 but showing the elevating apparatus in the upper loading position and with a wheelchair thereon;
  • Fig. 3 is a perspective view similar to Fig. 2, but showing the elevating apparatus supporting a wheelchair in stored position within the van;
  • Fig. 4 shows diagrammatically in side elevation the track means and first and second carriage means of the elevating apparatus
  • Figs. 5a and 5b show diagrammatically in side elevation the rear end of the floor plate assembly for supporting the wheelchair on the elevating apparatus, as well as the rear entry gate and operating means therefor;
  • Fig. 6 is a broken-away perspective view of the floor plate assembly and the adjustable safety gate towards its front end;
  • Fig. 7 shows diagrammatically in side elevation, partly broken away, the drive and lifting arrangements, the second carriage means being shown uppermost relative to the first carriage means, and
  • Fig. 8 is a similar view to Fig. 7 but showing the second carriage means in lowermost or ground- engaging position, relative to the first carriage means.
  • the elevating apparatus 10 shown in the drawings has first carriage means 11 and second carriage means 12, track means 13 being arranged to support the first carriage means 11 and to be mounted on a platform 14 constituted by the floor at the rear of a motor vehicle van 15.
  • the first carriage means 11 may be moved horizontally on the van floor or platform 14 from a stored position in the van as shown in Fig. 3 to an upper loading position overlapping the free edge 16 of the platform as shown in Fig. 2.
  • the second carriage means 12 is supported operatively by the first carriage means 11 and is mounted for vertical movement when the first carriage means is in the upper loading position of Fig. 2, whereby the second carriage means 12 can be transferred from the upper loading position of Fig. 2 to the lower loading position shown in Fig. 1 at or adjacent the ground or other base level means such as the floor of a building into which the van 15 is driven.
  • the horizontal track means 13 includes a pair of spaced parallel tracks 17 which are conveniently of I-section having upper horizontal webs 18 under which guide rollers 19 may engage.
  • the tracks 17 extend longitudinally of the van 15, and each track is traversed by one of a pair of cantilever beams 20 of the first carriage means 11, said beams 20 having said guide rollers 19 engaging beneath the webs 18 of the respective track 17 and another or top roller 21 engaging against the top face of the web 18 for guided motion of the first carriage means along the tracks 17.
  • the disposition of the latter enables loading and unloading through the rear door 22 of the van 15, and it will be noted that the door 22 is of such height that a loaded wheelchair may pass in and out of the van between the positions shown in Figs. 2 and 3.
  • the second carriage means 12 is mounted so that it can travel vertically relative to the first carriage means 11 between the positions shown in Figs. 1 and 2 when the carriage means 11 is clear of the van platform 14, there being fixed guide frames 23 on the first carriage means 11 to co-operate with upstanding frame members 24 of the second carriage means 12, the latter having upper and lower guide rollers 25 as illustrated.
  • the frame members 24 are thus able to move up and down in guided manner within respective upper guide channel members 26 which are themselves mounted for vertical raising and lowering in guided manner within fixed channel assemblies 27 of said fixed guide frames 23 of the first carriage means 11.
  • Power means are provided in the form of an electric motor 28 rigid on the first carriage means 11 and having a cross shaft 29 which at its opposite ends rotates a respective winder 30 for raising and lowering the guide channel members 26 and their supported lower upstanding frame members 24 in a two-stage telescopic-type action.
  • a respective winder 30 for raising and lowering the guide channel members 26 and their supported lower upstanding frame members 24 in a two-stage telescopic-type action.
  • Figs. 7 and 8 show the winders 30 rotatable by the motor 28 and operating a flexible lifting strap 31 which has its length extending around a fixed top pulley 32 and around a pulley 33 on the top of and movable with the guide channel member 26 before being secured at 34 near the top pulley 32.
  • winding of the flexible strap 31 causes the pulley 33 to rise to lift the members 24 which in turn reach the uppermost position in the guide members 26 and these continue lifting together to the positions shown in Fig. 7.
  • Any suitable guide or roller arrangements may be used between relatively movable parts and the motor 28 may be controlled by switches (not shown) including (1) an upper limit switch to prevent lifting further (2) a tension sensor switch to stop lowering actions once it has reached bottom position, and (3) a lower limit switch to stop if it has not bottomed.
  • the two-stage telescopic- type action as described enables the frame members 24 to be contained in the fixed guide frames 23 when the latter are of a height not substantially exceeding the designed lifting height of the members 24.
  • the latter have their lower ends secured to one end of the horizontal rectangular floor plate assembly 35 on which the wheelchair can be supported within the lateral confines of the entire lifting apparatus.
  • the plate assembly 35 includes parallel longitudinal side bars 36 between which an entry gate 37 extends but may be lowered as shown in Fig. 5a to permit the wheelchair to be driven thereon or raised as shown in Fig. 5b to prevent accidental removal.
  • the gate 37 is mounted for pivotal movement about a horizontal axis 38 between the bars 36 and has a lever 39 and toggle handle 40 to be arranged as an over-centre toggle lock when the gate 37 is raised as in Fig. 5b.
  • the end of the floor plate assembly 35 remote from the gate 37 has an adjustable safety gate 41 hinged and lockable in the same way as the gate 37 and adjustable in its distance from the gate 37, serving to provide safety for the feet of a person in the chair as well as general stability for chairs of differing lengths.
  • the upper or first carriage assembly 11 provides support and guidance for the second carriage 12 so that both can be moved horizontally to and from the van, using manual control, but only when the two assemblies are cantilevered from the platform can the second carriage means be lowered or raised.
  • Remote control of the motor may be effected by a switch pad 42 on an extensible cord 43, while Fig. 7 shows a manual control handle 44 which is removable but usable in an emergency in case of power failure.
