Each turn assist arrangement is coupled between the frame and a corresponding caster wheel assembly. Each turn assist arrangement is configured to bias the corresponding caster wheel assembly during an operator commanded turn, and to be overridden by forces applied by the ground to the caster wheel assembly. | 06-18-2009 |
20100059954 | Articulating Camera Transport Apparatus and Method - An articulating camera transport apparatus and corresponding methods involving an articulating camera truck for accommodating a camera element and for engaging a set of camera dolly tracks, the tracks having a curvature, the truck including a carrier and an undercarriage, the undercarriage having a plurality of articulating wheels and a structure for gimbaling the plurality of articulating wheels for accommodating the curvature and for facilitating a smooth passage of the truck along the tracks. | 03-11-2010 |
20120007325 | VEHICLE FRONT WHEEL PIVOT LOCK - A vehicle has first and second rear drive wheels that are driven independently of each other and a pair of front wheels that freely rotate about a vertical axis wherein the rear drive wheels and the front wheels are rotatably mounted to a frame. A locking mechanism is operatively connected to the pair of front wheels to restrain the rotation of the front wheels about the vertical axis and maintain the pair of front wheels in a forward position while the operator engages the locking mechanism. When the operator releases the locking mechanism, the locking mechanism is removed from the pair of front wheels and the pair of front wheels are free to rotate about the vertical axis. | 01-12-2012 |
20120068426 | Trailer Hitching and Tracking Steering - Improvements in a trailer hitching and tracking steering system are disclosed include a new style RV or wagon style RV that includes an extendable, variable position tow bar that accommodates misalignment of a tow vehicle. The tow bar can be rotated for storage within the RV wagon. Further improvements include a wheel steering mechanism to improve tracking of a towed vehicle using a bi-directional caster front suspension for steering a wagon style RV in both a forward and reverse direction. The caster of the front wheels is automatically re-directed depending upon the direction of travel of the RV. The suspension system includes a steerable rear suspension that minimizes the amount the back wheels will cut the corner when turning. The improvements also include the use of visible light beams to guide a tow vehicle backing up to an RV to be correctly positioned for hitching without assistance. | 03-22-2012 |
20130038034 | Industrial truck comprising a pair of wheel arms - An industrial truck comprising a pair of wheel arms, which at their free end in each case comprise a wheel arm end, each of which comprising a bearing body and a pair of load wheels, the load wheels in each case being rotatably mounted on a rocker, and the rocker being pivotably mounted on the bearing body in a region located between the load wheels, the bearing body comprising a bearing projection on which the rocker is mounted such that the rocker laterally defines the wheel arm end. | 02-14-2013 |
20130069329 | STROLLER CHASSIS, IN PARTICULAR FOR TRANSPORTING A CHILD - This stroller chassis comprises a frame ( | 03-21-2013 |
20140131966 | Bushing Securement Device - A skateboard bushing securement system is provided for improvement of skateboard truck stability and performance. Base washers having a raised annular ring are positioned on opposite sides of bushings engaged to the truck hanger. The annular rings are sized to engage around the circumference of the bushings. Sleeve washers having axially located projecting sleeves communicate against the base washers during compression. The projecting sleeves engage inside the axial cavity of the bushings on both sides of the hanger. Stability and performance is enhanced through the stabilization of both bushings axially and about their circumference by the annular rings. | 05-15-2014 |
20140284895 | DEVICE FOR LIMITING SWIVEL OF A WHEEL - A device for limiting swivel of a wheel includes a fixed seat, a positioning groove, a driving member, and a limiting member. The fixed seat permits a fork to be connected pivotally thereto, and permits a frame to be connected fixedly thereto. The driving member is connected rotatably to the fixed seat. The limiting member is mounted extendably and retractably on the fixed seat. The positioning groove is disposed to the fork. The limiting member is extendable from the fixed seat to engage the positioning groove so as to prevent rotation of the fork, and is retractable into the fixed seat to remove from the positioning groove to allow for rotation of the fork. The driving member has a caroming surface rotatable to drive extension and retraction of the limiting member. | 09-25-2014 |
20140361503 | WHEEL FRAME FOR A SKATEBOARD - An improved wheel frame for a skateboard, wherein slipping wheels connect with a skateboard body stably, comprises: a wheel frame main body having a screw hole on each side; two wheel axles for screwing in the screw hole of the wheel frame main body, wherein in each axle a through hole is set, the through hole has at least one longitudinal expansion joint in the thread for flexible expanding the diameter; and an expansion element for setting in the through hole of the both axles, wherein the diameter of the thread within the axle is forced to expand, so that the thread of the axles and the screw holes of the wheel frame main body are firmly held together. | 12-11-2014 |
20150298504 | CASTOR WHEEL ASSEMBLY - A trolley having two castor wheel assemblies mounted to a trolley frame. The castor wheel assemblies are mounted toward a rear of the trolley frame whereas another pair of conventional castors are mounted to the front of the trolley frame. The castor wheel assemblies are not identical insofar as swiveling of the assemblies is limited in a direction inwardly of the trolley only. It has been found that limited swiveling of one of the castor wheel assemblies only such as at an offset angle provides more efficient guided steering of the trolley. | 10-22-2015 |
