ATTORNEY ftiee Patented Nov. 23, 1954 VEHICLE LIFT Arthur H. Yordi, Kenosha, Wis. Application December 15, 1953, Serial-No. 398,264" 7 Ciaims. (Cl. 187-8.41)

This invention relates to a vehicle lift particularly adapted for use when repairing or lubricating-a vehicle.

It is an object of the present invention to provide a vehicle lift having an elevated work platform which will allow mechanics to have full access to the upper part of the vehicle, when the vehicle is in its elevated or lifted position, as- Well as to the underneath part for effecting repair and lubricating operations.

It is another object of the invention to provide a vehicle lift wherein guard rails will be lifted with the vehicle by its hoistso as to have them out of the way when the vehicle is in its lifted position and to allow full access from an elevated platform to the vehicle and wherein the elevated platform will be guarded when the vehicle is lowered to the ground position and away from the elevated platform, the guard rails being available at a time when the vehicle is lowered to prevent the mechanic or others from falling from the elevated platform.

It is another object of the invention to provide in a vehicle lift structure an overhead suspension which can be elevated and from which the vehicle can be suspended by block and tackle means connected to the vehicle at the respective opposite ends thereof so that at least one end of the vehicle can be retained in an elevated position independently of wheel supporting tracks of the lift, added access being given the mechanic to the vehicle and without the interference of the tracks of the lift, and wherein the guard rails form a part of the overhead structure so as to then be elevated therewith to an out-of-way position when the vehicle is elevated by the lift.

Other objects of the invention are to provide a vehicle repair and lubrication lift structure having the above objects in mind which is of simple construction, inexpensive to manufacture, has a minimum number of parts, rugged and secure, of pleasing appearance, easy to operate, and convenient and efiicient in operation.

For other objects and a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is a front perspective view of a vehicle mounted on a hydraulic lift and the lift in its lowered position with the inner guard rails in place on the elevated platform and the upper structure being in its lowered position;

Fig. 2 is a side elevational view of the structure with the upper structure elevated and the vehicle in its raised position and connected to block and tackle means at one end, the inner guard rails being elevated with the upper structure and the vehicle so easy access can be had to the top of the vehicle from the elevated platform.

Referring now to the figures, generally represents the standard hydraulic vehicle lifting hoist having spaced wheel supports 11 and 12 over which the vehicle wheels are driven to locate vehicle 13 upon the hoist 10. The respective tracks 11 and 12 have respectively upwardly extending inner guide rails 14 and 15. The tracks 11 and 12 are joined together by a transverse member 16 to which a hydraulic hoist cylinder device 17 is connected. Above the track hoist 10 and elevated from the ground is a U-shaped platform 19 held in a fixed manner and in its elevated position by six vertical supports 20, engaging with the outer edge of the platform and three such posts being longitudinally spaced from one another along each side of the platform. Each post 29 has a fixed guard rail support extending upwardly therefrom as indicated at 21 and between which extend fixed parallel spaced and vertically spaced guard rails 22 and 23. The front posts have inwardly extending guard rail projections 24 to prevent an attendant from Walking off the front end of the platform. Full length guard rails. extend across the opposite end of the platform and between the twoend guiderails support 21 at that location.

In order to gain access to the platform, see Fig. 2, there is an opening25 at the-rear end of the platform with which steps 26 communicate A rail 27 is disposed along one side of the opening 25' and a swing gate 23 is. located in front of the opening and the rail 27. This guards the opening 25 to prevent the mechanic from falling therethrough while working. on the top of the platform 19; A step ladder 29 can be left on the rear of the platform 19 for use when desired and can be moved over the platform to difierent locations along the side of the car. On the ground floor a work bench 341 is shown lying in back of the stairs or steps 26, Fig. 2.

Movable relative to the platform and adapted tov be lifted by the track hoist device lib is an overhanging structure indicated generally at 31. This structure comprises four depending supports 32, see Fig. 1, that are slidable through the platform and respectively through support bearings 33 which may be sleeve type as shown, on the top of the platform 19. These rods or support members 32 are elevated by the track hoist device 1 3 as the hoist device is movedupwardly with the vehicle 13 to position the vehicle at an elevationadjacent the platform 19, as shown in Fig. 2. The vehicle 13-will have been driven-on to the track hoist 10 in the usual manner and made secure thereon against rolling movement. The elevation of the track hoist takes upwardly the upper overhanging structure 31. This upper structure has curved

tie members

35 and 36 oining pairs of supports 32 at the front end of the device and at the rear end respectively. An intermediate curved member 37 is connected between the vertically movable rod members 32 by inner guide rails 38 and will be taken upwardly by the guide rails which interconnect the upper ends of the vertically movable rod members 32.

The

curved members

35, 36 and 37 are joined together by a longitudinally extending pulley track member 39 over which a pulley hoist device 40 can be adjusted to engage either the rear end of the vehicle or the forward end of the vehicle in the manner illustrated. This pulley hoist device has a hook 41 adapted to engage with the bumper of the vehicle or some other part thereof and when operated, will elevate the vehicle.

It will be seen that when the upper structure 31 has been elevated the guard rails 38 have been taken upwardly, as shown in Fig. 2, so that the mechanic will have full access to the top of the vehicle and around the same when the vehicle has been lifted to the elevation of the platform 19.

When the vehicle is lowered by the track hoist device 10, the guard rails 38 will be lowered along with the structure 31 so as to be placed adjacent to the inner edge of the platform 19 to prevent the mechanic from failing through the opening.

When the track hoist is raised to elevate the vehicle, the inner guard rails 38 will be elevated above the platform 19 so that they are out of the way of the mechanic desiring to Work on the vehicle from the platform. This makes it possible for two mechanics to work on the vehicle at same time, one from beneath and the other from above, with the mechanic working from below being in a standing position which is more comfortable than lying on his back beneath the vehicle. When the vehicle is lowered, the inner guard rails 38 will be lowered to the level of the platform to completely enclose the platform with guard rails. The vertical rods 32 pass through the sleeve bearing members 33, which are secured to the top of the platform.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
