Description
BACKGROUND OF THE INVENTION
This invention relates -to new and useful improve~
ments in wheel chair lift assemblies ~or vehicles. Con-ventionally, such vehicles, in the form of vans or the like, require means whereby the wheel chair can be enter-ed or removed from the vehicle and while it is easy to ; 15 manipulate it without the patient~being in the wheel chair, nevertheless it is extremely difficult when the patient is unable to leave the wheel chair conveniently.
,.
: ~' Various forms of lifts have been provided which elevates the wheel chair and patient level with the floor whereupon the patient can wheel the chair from the plat-form, through the doorway and onto the floor o~ the vehicle.
i:
.
However, these tend to be somewhat unsafe and ~; care has to be taken to ensure that the platform is pre-cisely level with the floor before the wheel chair can be moved either from the floor of the vehicle to the platform :

'~'~,.-'' DET~ILED DESCRIPTION
, ~ .
Proceeding therefore to describe the invention in detail, reference character 10 shows part of the body ~ ;
of a vehicle with 11 indicating one side of the doorway 10and 12, the ~loor of the vehicle in the interior of the body. ~;
The invention collectively designated 13 con~
sists of mounting structure generally designated 14 which, in this embodiment, includes a pair of spaced and parallel 15U-shaped channels 15 which c~re secured to the floor by any conventional means such as straps 16. -; ,. .. .
The channels 15 are secured so that the open sides 17 face one another inwardly thereby forming rails ~,~
for the mounting of support structure collec-tively designa- - :
ted 18. ::
::~
This support structure includes a pair of mem-, . .
bers 19 slidably engageable within the channels lS and capable of being moved inwardly and outwardly. In this connection, a plurali-ty o~ rollers 20 is preferably jour~
nalled for rotation upon the members 19 and engage the flanges of the channels 15 to facilita-te the inward and outward sliding movement of the members 19.
The channels 15 are situated upon the floor 12 -~
adjacent the doorway 11 so that the members 19 can extend through the doorway when in the extended position and can ;-retract within the doorway when in the innermost position.
In one or more of the claims, the innermost position is reerred to as the "vehicle interior position" and the out-ermost position as the "vehicle exterior position".
'~
The support structure 18 also includes vertical members 20 extending upwardly rom inboard o the members 19, and diagonal braces 21 extending rearwardly rom the ;
upper ends o members 20 to be connected to the inner aces o~ the members 19. Further members 22 extend forwardly ;
rom the members 20 and are secured to vertical standards `
23 which extend upwardly rom the extremities 24 o the members 19. These vertical standards 23 are also U-shaped channels with the open sides acing inwardly and are situa-ted in spaced apart parallel relationship as clearly shown.
: .:
The support structure also includes -the wheel ` ;
chair support platorm collectively designated 24A which ;
~, .
~;
,. .. , : ~
7~55 ~
is secured to the lower end of members 25 which in turn are each mounted for vertical movement within the channel standards 23, being retained therein by one or more cross ;~
straps 26 spanning the open ends of these channels. The ;~
; 5 support platform includes the planar panel 27 which extends - .
forwardly and rearwardly of the members 25 with diayonals -~
28 supporting the front end and extending upwardly and rear~
wardly to the members 25 as clearly shown in Figure 1.
' ~
Retainer sides 29 extend upwardly from each side ;
edge of the panel 27 rearwardly of the members 25 as clearly shown.
r~embers 25 include anchors 30 upon the upper ends thereo~ within the channel standards 23 and wire cables or the like 31 extend upwardly from these anchors and over sheaves 32 situated at the upper ends of the channel stan~
dards 23 and then extend to a winch assembly 33 which may .,; "
be secured to the side of one of the channel standards 33.
This winch may be actuated either manually, electrically, hydraulically or pneumatica:Lly, but is preferably electric~
ally operated from the battery 34 of the vehicle.
... ..
Under these circumstances, the winch is operated - by an electric motor 35 which is a reversible DC motor and controlled by means of a forward and reverse switch 36 in the usual way.
.
_ 6 . . , '. ;
~L0~7555 ; ~`
In operation, it will be assumed that the wheel - chair support structure 24A is in the uppermost position ; and that the entire assembly has been moved inwardly upon the rails 15 so that it is situated internally of the vehi- ~ i S cle adjacent the doorway 11. ~- ;
,~ ; ,.
The assembly is first manually extended to the , exterior position of the vehicle so that the wheel chair support assembly ~4A is supported cantilever wise upon the ends of the member 19, whereupon the winch 33 is opera-ted to lower the wheel chair platform downwardly until it ; engages the ground surace. A wheel chair together with a ~/ patient (not illustrated) is then wheeled upon the platPorm and secured by saPety straps 37 to steady the wheel chair on the platPorm. The winch is then reversed so that the platform is moved upwardly between the members 19 so that the underside of the platform is slightly above the floor 12 of the vehicle whereupon the entire assembly is pushed "
inwardly along rails rails 15 so that the assembly together with the wheel chair and patient are completely within the ~;
vehicle whereupon, if necessary, the platform can be lower~
ed to the floor 12 of the vehicle and the wheel chair can be moved off the platform and into the vehicle at which time the safety straps 37 may be used to detachably se~ure ~ ~ -the wheel chair to the floor of the vehicle in a conventional manner.
When it is desired to unload the patient and , - 7 -10~5iSS ;
` :'`, wheel chair, the reverse procedure is undertaken so that ~:~
the wheel chair can then be wheeled off the platform and onto the ground surface.
It should also be noted that one set of safety straps 37 may be provided to fasten in front of the patient to act as a lap seat belt, if desired.
Since various modifications can be made in my ~
invention as hereinabove described, and many apparently `:~ :
widely diferenk embodiments of same made within the spirit and scope oE the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be ;
interpreted as illustrative only and not in a limiting sense. ~ `
