Travel trailer stabilizer system |
摘要 |
A travel trailer stabilizing system having a right and left compound above-axle strut for bracing a trailer body at the axle or axles, each compound strut having an overlever arm for applying a stiffening force with a mechanical advantage to oppose any oscillatory motion of the frame on the tires. The mechanical advantage of the lever is configured to transfer a part of the weight of the trailer from the tires to the rigid struts. |

1. An at-park stabilizer system for a travel trailer, said stabilizer system comprising a pair of struts defining a right compound strut and a left compound strut, said pair of struts for mounting one on each side of a frame of a trailer at an axle or a pair of tandem axles, each of said compound struts comprising:
a) a base member having a footpad; b) an extension arm extending from said base member, said extension arm having a foot end and a head end, wherein said foot end is hingedly mounted on said base member and a transverse pivot axis is disposed proximate to said head end; c) an overlever arm pivotably mounted on said transverse pivot axis, said transverse pivot axis defining a fulcrum that divides the overlever arm into a long arm segment comprising a first end and a short arm segment comprising a second end of said overlever arm such that said long arm segment and said short arm segment have a ratio of lengths thereof, said ratio defining a lever with a mechanical advantage when pivoted on said fulcrum, said overlever arm having a cocked position in which said long arm segment is disposed on said fulcrum at an acute pivot angle above said extension arm and a locked position in which said long arm segment is disposed on said fulcrum at essentially a zero pivot angle relative to said extension arm; d) a mounting bracket member enabled to rigidly attach to said frame proximate to said axle or pair of tandem axles; wherein said mounting bracket member is configured for engaging said second end of said overlever arm; and, wherein said pair of struts are capable of being operated cooperatively, one on each side of said frame at an axle or pair of tandem axles. |
