20130249191 | Folding drop leg for a trailer jack - A folding drop leg for a trailer jack for supporting a trailer jack where added length is needed. The folding drop leg includes a base plate, a automatic locking swing plate, and a leg. The base plate is mounted to the bottom of the trailer's existing jack. The automatic locking swing plate is mounted to the base plate by use of a hinge pin and is swung upward when towing and dropped down to provide a stand for supporting the trailer when disengaged from the tow vehicle. The leg is mounted to the bottom of the automatic locking swing plate to add additional length to the existing jack leg rapidly when needed. | 09-26-2013 |
20140159340 | TRAILER STABILIZER - A trailer stabilizer and signaling system comprising: (a) a repositionable freight trailer stabilizer comprising a frame having mounted thereto a wheel, the repositionable freight trailer stabilizer including a repositionable jack; and, (b) a stabilizer signaler operatively coupled to the trailer stabilizer, the stabilizer signaler including a deployable signal configured to confirm the trailer stabilizer is secured under a parked freight trailer. | 06-12-2014 |
20140159341 | SUPPORT DEVICE FOR A SEMI-TRAILER - A support device for a semi-trailer or the like, that includes an outer support tube having an interior and an inner support tube, wherein the inner support tube is arranged in telescopic fashion in the outer support tube, a spindle mechanism located within the interior of the outer support tube, wherein the inner support tube is moved in the axial direction relative to the outer support tube by the spindle mechanism, and wherein the spindle mechanism comprises a multi-part spindle having a plurality of segments arranged in the axial direction and connected to one another in a flexible manner. | 06-12-2014 |
20140353942 | Travel Trailer Stabilizer System - 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. | 12-04-2014 |
20150360653 | JACK ASSEMBLY - A jack assembly including a telescopic column driven via a gear box, wherein: the gear box is coupled to a rotary input of a drive mechanism that extends and retracts the column; the gear box has only a single input gear and a single output gear that is coupled to the drive mechanism; and the input gear has a connector adapted to be engaged and driven by a portable, hand-held power tool. The invention also relates to a jack assembly with a gear box for use as a jockey wheel for attachment to a towed vehicle, to raise and lower a draw bar of the vehicle. | 12-17-2015 |
20160001691 | MOBILE STRUCTURE HAVING SUFFICIENT INTERNAL STRUCTURAL RIGIDITY TO ELIMINATE LOAD-BEARING PERIMETER SUPPORT STRUCTURES - A mobile structure includes first and second rigid frames and first and second horizontal roof supports supported by the rigid frame. Each of the rigid frames includes a first vertical support, a second vertical support substantially parallel to the first vertical support, and a lateral rigid frame support extending perpendicularly at least from the first vertical support to the second vertical support. The mobile structure further includes a floor under the first and second horizontal roof supports, a wheel-axle assembly under the floor, and leveling assemblies that are extendable away from the floor. Each leveling assembly is in weight-bearing and in-line relationship with respect to one of the vertical supports of the first rigid frame. | 01-07-2016 |
20160001750 | TRAILER LEG SECURING DEVICES AND SYSTEM - Devices and systems for securing and locking tractor trailer support legs in the down position are described herein. A securing pin passing through one of the support legs of a trailer while in the down position prevents the trailer legs from being raised. The pin can be locked in place such that only authorized users may remove the pin, raise the support legs, and move the trailer. A variety of kits for retrofitting existing trailers with securing devices are also provided. | 01-07-2016 |
20160113189 | JACK STAND FOR AUTO-CONNECT ASSEMBLY - A coupling assembly couples an implement to a vehicle having a pickup hitch. The coupling assembly includes a coupler frame attached to the implement. A jack stand member is mounted on two coupling pins which project from the coupler frame. The jack stand member has a first slot which receives the first pin and a second slot which receives the second pin. The second slot forms a first shoulder which engages the second pin to support the coupler frame when the jack stand member is in a ground engaging lowered position. A block mounted to the pickup hitch is spaced apart from the jack stand member to allow it to fall to the lowered position when the coupler frame is uncoupled from the vehicle. The block engages a surface of the jack stand member to raise the jack stand member when the coupler frame is moved towards the vehicle. | 04-28-2016 |
