OMNI-DIRECTIONAL SELF-ORIENTING BREAKAWAY STRUCTURES
An omni-directional self-orienting structure for a motorcycle, ATV, UTV, off road vehicle, snowmobile, bicycle or other vehicle. The structure extends from the vehicle and will deflect or breakaway under an applied force such as an impact, for example by a tree branch strike or crash. The structure can re-position and re-orient itself once the force is removed. Examples of the structure are hand guards, side mirrors, turn signals, extended lights, mounts and antennas. Apparatus and method claims are provided.
1 . An omni-directional self-orienting breakaway hand guard mounted on a vehicle comprising:
a main chassis attached to an exterior of the vehicle, the main chassis further comprising a first mated surface;
a shield assembly, the shield assembly further comprising a shield and a shield housing securing the shield, the shield housing further comprising a second mated surface;
a pair of mated surfaces comprising the first mated surface and the second mated surface wherein the main chassis and the shield assembly communicate via the pair of mated surfaces; and
a shaft assembly passing through the main chassis and the shield assembly, thereby creating elastic compression on the pair of mated surfaces as between the main chassis and the shield assembly to place the shield assembly in a desired position and orientation with respect to the main chassis.
2 . The omni-directional self-orienting breakaway hand guard of claim 1 wherein the first mated surface is a plug and the second mated surface is a socket configured to accommodate the first mated surface.
3 . The omni-directional self-orienting breakaway hand guard of claim 1 wherein the first mated surface is shaped as a multi-sided pyramid, and the second mated surface is shaped to accommodate the first mated surface.
4 . The omni-directional self-orienting breakaway hand guard of claim 1 wherein the first mated surface is shaped as a four-sided pyramid, and the second mated surface is shaped to accommodate the first mated surface.
5 . The omni-directional self-orienting breakaway hand guard of claim 1 wherein the shaft assembly further comprises a first end, a flexible middle portion, and a second end.
6 . The omni-directional self-orienting breakaway hand guard of claim 5 wherein the flexible middle portion is a cable.
7 . The omni-directional self-orienting breakaway hand guard of claim 6 wherein the flexible middle portion of cable is swaged to the first end and second end.
8 . The omni-directional self-orienting breakaway hand guard of claim 5 wherein the second end of the shaft assembly is threaded, and the shaft assembly further comprises a nut to secure the shaft assembly within the main chassis.
9 . The omni-directional self-orienting breakaway hand guard of claim 1 wherein the shaft assembly comprises a spring to provide elastic compression.
10 . An omni-directional self-orienting breakaway side mirror mounted on a vehicle comprising:
a main chassis attached to an exterior of the vehicle, the main chassis comprising a first mated surface;
a mirror assembly, the mirror assembly comprising a mirror and a mirror housing for securing the mirror, the mirror housing comprising a second mated surface;
a pair of mated surfaces comprising the first mated surface and the second mated surface, wherein the main chassis and the mirror assembly communicate via the pair of mated surfaces; and
a shaft assembly passing through the main chassis and the mirror assembly, thereby creating elastic compression on the pair of mated surfaces as between the main chassis and the mirror assembly to place the mirror assembly in a desired position and orientation with respect to the main chassis.
11 . The omni-directional self-orienting breakaway side mirror of claim 10 wherein the shaft assembly further comprises a first end, a flexible middle portion, and a second end.
12 . The omni-directional self-orienting breakaway side mirror of claim 11 wherein the flexible middle portion is a cable.
13 . The omni-directional self-orienting breakaway side mirror of claim 12 wherein the flexible middle portion of cable is swaged to the first end and second end.
14 . The omni-directional self-orienting breakaway side mirror of claim 11 wherein the shaft assembly comprises a spring to provide elastic compression.
15 . The omni-directional self-orienting breakaway side mirror of claim 11 wherein the vehicle is a four-wheel offroad vehicle and the exterior of the vehicle where the main chassis is attached is a roll cage.
16 . A method of assembling an omni-directional self-orienting breakaway structure for a vehicle, comprising steps of:
providing a main chassis, the main chassis having a first mated surface;
providing a functional assembly, the functional assembly having a second mated surface;
providing a shaft assembly;
installing the shaft assembly through the main chassis and the functional assembly, wherein the first mated surface and the second mated surface are in a mated configuration, and wherein the main chassis and the functional assembly communicate under compression from the shaft assembly.
17 . The method of claim 16 , wherein the functional assembly is a shield assembly.
18 . The method of claim 16 , wherein the functional assembly is a mirror assembly.
19 . The method of claim 16 , wherein the shaft assembly comprises a first end, a second end and a middle flexible portion.
20 . The method of assembling an omni-directional self-orienting breakaway hand guard of claim 16 wherein the shaft assembly comprises a first end, a second end and a middle flexible portion, wherein the middle flexible portion is a cable, the method further comprising steps of: (i) swaging the cable to the first end and (ii) swaging the cable to the second end.
