DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring generally to FIGS. 1, 2 and 3 there is a seat frame 1 and a three wheeled movable carriage 3. The seat frame 1 has a seat thereon 5 which is a bucketseat from an automobile. The seat 5 is fastened to an undercarriage 7 by fastening means (not shown). The undercarriage 7 has Nylon slide blocks 9 which permit it to be slid off or onto the movable carriage 3 with minimal frictional resistance with the movable carriage 3. The Nylon slide blocks 9 move over T-shaped rails 11 which are fastenable at various sectable positions longitudinally of the movable carriage 3 by means of bolts (not shown) passing through selected aligned ones of openings l3 and 15 in the rails 11 and on a frame part 17 of the movable carriage 3 respectively see FIG. I. The position of fastening is, in use, selected so that the centre of mass of the invalid is generally central of the movable carriage 3 to provide general stability to the aid. Such position will be different for different invalids depending on their particular incapacity.
Each of the rails 11 has an upwardly extending flange portion 19 at the rearmost end thereof with an aperture 21 therethrough. The aperture 21 is positioned so that a generally horizontally extending pin 23 at each side of the rearmost end of the undercarriage 7 can pass therethrough. A locking pin 25 on a safety chain 27 is then fitted through a generally vertically extending aperture 29 in the pin 23 to lock the undercarriage 7 to the movable carriage by locating behind the flange portion 19.
An inturned lug 31 see FIGS. 1 and 2 and 3 on the underneath of the undercarriage 7 locates underneath a forward part of the horizontally extending flange part of one of the rails 11 to resist backward swinging of the seat and undercarriage when on the movable carriage 3. It will be noted that the rail 11 which the inturned lug 31 locates under is downwardly inclined with respect to the other rail 11 see FIG. 2. The purpose of this will be explained later.
The undercarriage 7 has arm rests 33 and extendible leg supports 35 for supporting respectively the arms and legs of an invalid.
The undercarriage 7 has, on the invalids left hand side thereof, two roller support engaging members 37. The members 37 are ball roller bearings but other members such as Nylon headed members or wheel members may be used. The members 27 are used when moving an invalid into or out of an automobile as will be explained later.
Underneath the undercarriage 7 there are three ball transfer rollers 39 which are used when moving an invalid into or out of an automobile.
The movable carriage 3 has a frame comprising a central trunk 41 with a forward wheel 43 mounted for rotation thereto in a castor type carriage mechanism 45. The carriage mechanism is free to swing about a vertical axis thereby permitting relatively easy manoeuvering of the aid when moving around corners. Mounted forwardly of the wheel 43 is a foot tray 47 which is swingable upwardly about a horizontal axis from the position shown to make the aid more compact when not in use. At the rear of the trunk 41 the frame has an axle which supports two wheels 49 for rotation. The rails 17 are held in operative spaced apart relation above the rear wheels 49 by frame members 51.
A brake mechanism 53 is mounted on the movable carriage 3 on the underside of rails 17. Such mechanism comprises two shaft supporting brackets 55, a shaft 57 supported for rotation therein, an operating lever 59 and two eccentric cam action brakes 61. In the position shown in FIG. 1 the brake is in the off position. To cause the brake to operate the lever 59 is rotated to cause the cam brakes 61 to engage with the associated rear wheel 49 to prevent rotation of that rear wheel.
Referring now to FIGS. 4 to 9, the automobile 60 has a support 61 fastened to the passenger door. The support 61 is of elongate C channel section and extends generally horizontally the full length of the door. The open face of the C channel faces the interior of the automobile and is provided so that the axle 63 of the members 37 can fit between the opening.
The floor of the automobile is fitted with a planar horizontally extending floor part 65 of plate steel.
In use, when moving an invalid into an automobile the passenger door is opened and one or both of the leg supports 35 is extended and the invalids legs placed thereon. The aid is then pushed towards the automobile so that the support engaging members 37 locate in the support 61.
With such a manoeuver the wheeled carriage 3 moves underneath the automobile see FIG. 6.
The pin 25 is then removed from locking the seat and undercarriage from the wheeled carriage 3 and the seat and undercarriage are then pushed into the automobile the transfer rollers 39 rolling over the floor part 6 and the support engaging members 63 rolling and/or sliding along the support 61.
During such transfer the weight of the invalid plus the weight of the seat and undercarriage are shared between the door, the floor part 65 and in the initial stages of manoeuv Qng the movable carriage 3.
When the seat ah% undercarriage are moved off the wheeled carriage 3 to the forwardmost position in the support 61 as shown in FIG. 6, the undercarriage 3 is removed. The door is then closed the transfer rollers 39 allowing the seat and undercarriage to move over the floor part 65.
The seat and undercarriage are then in the position as shown in FIG. 7.
The undercarriage and seat are then moved rearwardly in the automobile so that a threaded pin 70 and co-operating nut 71 locate in a recess in a flange 73.
The co-operating nut 71 is then screwed to clamp against the flange 73 to hold the undercarriage and seat in that position in the automobile.
Removal of the invalid is achieved by the reverse procedure.
To assist supporting the automobile at a given height above ground level corresponding to a transfer height for the undercarriage and seat onto the movable carriage a chock 75 see FIG. 4 is fitted under the automobile. This is particularly provided for when the weight of the invalid, undercarriage and seat are partly taken on the door, the extra moment created thereby does not cause the transfer level to drop below a predetermined level.
The reason for the downwardly inclined rail 11 is to provide for any dropping of the transfer height when the door is opened.
In a modification of the above a roller (not shown) may be mounted on the floor part 65 to engage with a forward edge of the undercarriage to automatically push the seat rearwardly to lock with the flange 73 when the door is closed. Additionally the seat frame may be provided with a finger which engages with such roller to cause the undercarriage to move forwardly when the door is opened to unlock from the flange 73.
