6 Claims.
The present invention pertains to a novel ski suspension for snow vehicle bodies, such as motor sleds, trailers and the like.
The principal object is to provide a spring suspension in such a structure. Another object is to provide a smooth running, durable and inexpensive device of this character and one that is easily assembled and repaired.
These objects are accomplished by a leverage and spring system between each ski and the 'vehicle body. Briefly, a pair of lever arms are intermediately fulcrumed near the ends of the ski and joined by a spring connecting their inner ends. Their outer ends are suspended from the vehicle body, one by a rigid bracket and the other by a pivoted shackle. Displacement of the ski at either or both ends, or a load on the vehicle,
causes movement of the levers relatively to the ski and hence tension in the spring.
The invention is fully disclosed by way of example in the following description and in the accompanying drawing in which:
Figure l is a side elevation of the device;
Figure 2 is a perspective view, and
Figure 3 is a detail section.
Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout. a In Figures 1 and 2 is shown the floor, platform or other structural member I of a vehicle intended to run on skis such as a trailer, for example. The skis and their suspensions are provided in any given number at the desired locations.
For each such suspension there is provided a bracket 2 secured to and suspended from the member I. Its lower end is forked at 3 to receive a pair of lever arms 4 pivotally held at one end by a shaft or pin 5. Beneath the bracket 2 lies a ski runner 6, on which are mounted two ears I to which the levers 4 are fulcrumed at 8. The remaining ends of the-levers carry a pin 9 on which is mounted a U-shaped clip I0.
To this clip is attached one end of a coil spring II by means of a bolt and nut, or equivalent device l2. In the other end of the spring is fitted a plug I3, and into the plug is threaded a screw I4 locked by a nut I5.
The rearward portion of the runner 6 carries a pair of lug I6 similar to the lugs 1. On these lugs are fulcrumed a pair of lever arms H The forward ends of the arms support a pin I8 to which is fastened one end of a clip I9 by a bolt 20. The other end of the clip is in the nature of an upturned flange 2| in which the rear end of the screw I4 is received and held by a nut 22.
Above the levers II, a shackle is suspended from the member I. It consists of a horizontal rod 23 fastened to the member I and having a pair of links 24 suspended therefrom. The lower ends of the links receive between them the rear ends of the levers II, to which they are attached by a shaft or pin 25.
The ski 6 may be provided at its lower surface with a runner consisting of a longitudinal strip 26 and beneath it a metal strip 21, both secured to said surface in any suitable manner.
In the operation of the device, a displacement of the ski 6 relatively to the body member I results in a pivotal movement of the levers 4 and I1 and hence in expansion of the spring II, accompanied by a pivotal movement of the links 24 on the pin 23. This action occurs whether the displacement is at either end or both ends. A load on the vehicle or a shock on the ski effects such displacement. Thus, the weight of the vehicle is sprung by the spring II at each of the runners.
Although a specific embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.
What I claim as my invention is:
1. In combination with a vehicle body, a runner beneath said body, a pair of levers having an intermediate pivotal point attached to said runner and spaced lengthwise of the runner, a spring joining the inner ends of said levers, and means pivatolly connecting the outer ends of said levers to said body.
2. In combination with a vehicle body, a runner beneath said body, a pair of levers having an intermediate pivotal point attached to said runner and spaced lengthwise of the runner, a spring joining the inner ends of said levers, members suspended from said from said body, the outer ends of said levers being connected to said members.
3. In combination with a vehicle body, a runner beneath said body, a pair of levers having an intermediate pivotal point attached to said runner and spaced lengthwise of the runner, a spring joining the inner ends of said levers, a bracket suspended from said body, a shackle pivotally suspended from said body, the outer ends of said levers being pivotally attached respectively to said bracket and shackle.
4. In combination with a vehicle body, a runner beneath said body, a pair of lugs mounted on said runner and spaced lengthwise thereof, a pair of levers having an intermediate point att ched to said lugs, a spring joining the inner e ds of said levers, and means pivotally connecting the outer ends of said levers to said body.
5. In combination with a vehicle body, a runner beneath said body, a pair of transversely spaced levers pivotally mounted near each end of said runner and having an intermediate fulcrum, a pin passed through the inner ends of each pair, a spring joining said pins and lying lengthwise of said runner, and means pivotally connecting the outer ends of said levers to said body.
6. In combination with a vehicle body, a. runner beneath said body, a pair of transversely spaced levers pivotally mounted near each end of said runner and having an intermediate fulcrum, a pin passed through the inner ends of each pair, a spring joining said pins and lying lengthwise of said runner, a bracket suspended from said body, a shackle pivotally suspended from said body, the outer ends of said levers being pivotally attached respectively to said bracket and shackle.
