Each spike of a plurality of spikes is inserted into a respective one of each of the spike holders. Each of the spikes has telescopic functions for adjusting the position relative to each of the spike holders. A plurality of support beams has a distal end and a proximal end relative to the base. The proximal end of each of the support beams is coupled to the back surface of the base and the distal end of each of the support beams is coupled to a mounting base.

A method and apparatus for connected deployable arms off of cylindrical surfaces including an outer cylinder defining an outer circumference and an inner cylinder concentric with the outer cylinder around a central aperture, one or more primary developable mechanisms linked to one or more secondary developable mechanisms. The deployable arms transition from a first closed state wherein the primary developable mechanisms and secondary developable mechanisms are contained entirely within the outer cylinder outer circumference to a second open state wherein the inner cylinder rotates relative to the outer cylinder, forcing the primary developable mechanisms and secondary developable mechanisms to extend outside the outer cylinder outer circumference.

An all-terrain load transport system including a cylindrical first base member and at least three pairs of arms is provided. A handle is removably attached to an attachment member disposed on the cylindrical first base member. The cylindrical first base member defines a space for receiving at least one piece of accessory equipment. Each pair of the three pairs of arms defines a wheel support assembly at an end of each pair distal from an outer periphery of the cylindrical first base member. The three pairs of arms are detachably attached to the outer periphery of the cylindrical first base member. The wheel support assembly includes a cylindrical second base member defining a space for receiving a spherical wheel. The spherical wheel moves omnidirectionally within the defined space. Roller bearings positioned along an inner periphery of the cylindrical second base member facilitate the omnidirectional movement of the spherical wheel.

A three-layer soft rubber shock absorbing wheel including a hub. An outer surface of the hub is bonded with a hard body, a first layer of tread and a second layer of tread having a hardness lower than that of the first layer of tread. The hard body, the first layer of tread, and the second layer of tread are arranged from inside to outside in sequence. The second layer of tread is bonded in a concave surface portion on an outer surface of the first layer of tread. The first layer of tread and the second layer of tread are both elastic bodies. The hard body is configured to have an I-shaped structure body. The three-layer soft rubber shock absorbing wheel is a wheel body made by bonding three layers of materials with different hardness.

This invention is an improvement to the universal brake system (UBS) with adjustable wheel traction system (WTS). It adds a smart wheel that operate as a standalone adjustable wheel traction system with no connections to a vehicle's ABS brake system. The smartphone integrate with the wheel traction system to provide the following features: 360-degree collision avoidance, 360-degree parking guidance, 360-degree vehicle security and emergency calling. The smart wheel can also integrate with the UBS to obtain wheel lock features. The smart wheel utilizes four radially spaced spikes separated by 90 degrees that operate individually via linear actuators. Each smart wheel has a wireless remote terminal unit embedded in each wheel that measures the angular velocity of each wheel with one wheel serving as a master remote terminal unit that monitors the speed of each wheel to determine when slip or skidding occurs and when to extends wheel spikes.

A spoke wheel includes a rim for supporting a tire having rim guards, a hub located radially inwardly with respect to the rim, and a plurality of spokes integrally connected with the rim and the hub at outer and inner ends, respectively, and extending radially with respect to the hub; a laterally outer surface of the outer end of each spoke and a laterally outer peripheral edge of the rim are located laterally inwardly with respect to a tip of a laterally outer rim guard; outer ends of main spokes among the spokes are provided with convex portions projecting laterally outwardly and extending in the radial direction, and a lateral position of a laterally outer tip of each convex portion lies in the range between a lateral position of the laterally outer peripheral edge of the rim and a lateral position of the tip of the laterally outer rim guard.

A wheel including a substantially radially rigid rim; a hub for mounting the wheel to an axle; and, a plurality of actuators coupling the hub to the rim, the plurality of actuators being adjustable to control a hub position, the hub position being a position of the hub relative to the rim, and wherein at least some of the plurality of actuators act outside a plane of the rim.

A caster wheel assembly for an outdoor power equipment machine includes a wheel mount and provides a double bell-shaped caster wheel including two bell-shaped halves, each bell-shaped half includes a central hub, a smooth transition portion, an outer circumferential rim, and a planar face. A ground contacting tread can be provided by the outer circumferential rims. A ground contacting tread can be provided by a resilient tread ring positioned between the two bell-shaped halves.

A vehicle recovery board including an inner layer fabricated from a first material, the inner layer including a first face and an opposed second face, in which the first face and the second face each include a plurality of inner layer projections extending outwardly therefrom; and an outer layer fabricated from a second material, the outer layer is configured to substantially overlie the first face and the second face of the inner layer, in which the outer layer includes a plurality of outer layer projections extending outwardly therefrom, in which at least a portion of the plurality of outer layer projections are formed over at least a portion of the inner layer projections.

In a heavy duty orbital caster assembly that includes a rotatable wheel unit joined to a transfer plate that pivots about a mounting post extending from a mounting plate adapted to be secured to the bottom surface of an object, the improvement comprising a pair of roller bearing assemblies that extend upwardly from the upper surface of the transfer plate adjacent to the caster wheel post as it extends through its bearing. The rollers impinge on the lower surface of the mounting plate, and serve to transfer some of the load of the supported object directly to the caster wheel, enabling the support of very heavy loads.
