| 276 | PORTABLE ESCAPE DEVICE FOR SELF-RESCUE IN CASE OF AUTO TYRE BEING TRAPPED IN PIT | US15760221 | 2016-02-02 | US20180250980A1 | 2018-09-06 | Xingyan LI |
| Disclosed is a portable escape device for self-rescue in the case of an auto tyre being trapped in a pit, comprising support posts, a clamping device fitted to the support posts, and a jacking device fitted to the clamping device. The support posts are fixedly mounted onto spokes. The clamping device clamps an auto tyre. The jacking device protrudes and extends out of a top face of a tyre portion. The portable escape device for self-rescue in the case of an auto tyre being trapped in a pit can release the trapped auto tyre and perform self-rescue fast and reliably, and is convenient to carry. | ||||||
| 277 | Wheel for center pivot irrigation system | US15078878 | 2016-03-23 | US09962992B1 | 2018-05-08 | Dustin Covey |
| A center pivot irrigation system wheel including a hub having an axis of rotation and having lateral and oppositely lateral sides; a plurality of spoke pairs having distal ends and having proximal ends, each proximal end being attached to the hub, each spoke pair having lateral and oppositely lateral spokes, each lateral spoke being intersected by an axially extending plane of orientation, and said each oppositely lateral spoke being intersected by the same plane of orientation; a first plurality of axially extending through spaces, each through space being bounded by an adjacent pair of the spoke pairs; an annular rim having an outer surface, the distal end of each spoke being fixedly attached to the rim; and a plurality of treads, each tread being fixedly attached to the annular rim's outer surface. | ||||||

| A magnetic roller for being rotatable on a ferromagnetic surface is provided. The magnetic roller includes a roller wheel having an inner space, a magnetic array arrangement and at least one first drive mechanism. Further, the magnetic array arrangement is adapted to be swivelably disposed within the inner space of the roller wheel. The magnetic array arrangement includes a strong adhesion force side and a weak adhesion force side. Furthermore, the first drive mechanism is configured to swivelably drive the magnetic array arrangement. The first drive mechanism swivelably drive the magnetic array arrangement to direct the strong adhesion force side towards the oncoming ferromagnetic surface, and, to direct the weak adhesion force side towards the foregoing ferromagnetic surface to enable the roller wheel to move forward on the ferromagnetic surface. | ||||||

| A tire rim of a motor vehicle includes a substantially cylindrical body for holding a tire, and a hub connected to the body through radial members, and has an outer face facing, in use, the outside of the vehicle, and an opposite inner face. At least one elongate flexible element associated with the rim can reach a resting configuration within the rim, and a working configuration, extended with respect to the resting configuration, of such a length as to allow the tire to be surrounded, in which each flexible element is wound around the tire to form a snow chain. The rim includes at least one retaining member at a zone of its inner face, to be engaged by a portion of a flexible element in its working configuration. | ||||||

| A transformable wheel includes a wheel frame including a plurality of contact portions and a plurality of recessed portions. A plurality of transforming members is provided wherein one side of each transforming member is rotatably coupled to a corresponding one of the recessed portions and an outer surface of each transforming member forming a portion of the wheel frame. A rotating member is provided at one side surface of the wheel frame, and includes a plurality of transformation locking members arranged radially from the central axis of the wheel frame to correspond to the plurality of transforming members, respectively. A driving member is configured to rotate the rotating members by a preset angle about the central axis of the wheel frame. | ||||||
