Abstract:
A bolt assembly provides a reciprocating bolt. The bolt assembly includes a bolt assembly body, a cap affixed to the bolt assembly body, and a base affixed to the bolt assembly body opposite the cap, wherein the bolt assembly body includes a bolt carrier having a cap end disposed proximally to the cap and a bolt receiving end disposed distally from the cap. The bolt assembly also includes a biasing mechanism biasing the bolt carrier in a retracted position relative to the bolt assembly, and an extension actuator including a diaphragm having a center portion disposed between the cap and the bolt assembly body, the center portion of the diaphragm being deflectable to enable the biasing of the bolt carrier in the retracted position, the center portion of the diaphragm being oppositely deflectable to apply an actuation force to the cap end of the bolt carrier so as to move the bolt carrier from the retracted position to an extended position relative to the bolt assembly.
Abstract:
An all-weather tire includes features that enhance safety and usability in a variety of driving conditions as well as some manufacturing processes that may be used during the production and provides an all-weather tire having selectively deployable and retractable studs for greater traction when needed. The tire includes a toroidal shell enclosing an air-filled chamber and a plurality of stud actuation chambers contained within the shell for selectively deploying studs to extend past the tire's outer radial surface for engaging a roadway or surface. The studs may be retracted when no longer needed. A mechanical pump assembly or plurality of such assemblies powered by compression of the tire engaging the roadway may be used as a power source for generating pneumatic pressure and an internal valve assembly or assemblies may be used to route the pneumatic pressure appropriately. The pump and valve assemblies may be controlled either mechanically or electrically.
Abstract:
Apparatuses, methods, and systems associated with traction devices for vehicle tires are disclosed herein. In various embodiments, a tire may include a tread material bonded with a casing, the tread material having a tread pattern and one or more tractive devices may be disposed within voids in the tread pattern. In some embodiments, a media passage may be disposed between the tread material and the casing substantially under one or more of the voids in the tread pattern, the chambers and/or channels being controllable to urge movement of a corresponding tractive device.
Abstract:
A tire traction enhancement system and method of use are provided. In one form, a tire traction enhancement system includes a standard vehicle tire including perforations along the standard vehicle tire tread. The tire traction enhancement system further includes a first annular inner tube running substantially the inner circumference of the standard vehicle tire and a second annular inner tube between the first annular inner tube and the outer circumference of the standard vehicle tire. The second annular inner tube further includes a plurality of studs fastened to the outer circumference of the second inner tube and fastened to the perforations along the standard vehicle tire tread.
Abstract:
A vehicle tire 10 is provided. The tire 10 includes an outermost member 12 having a plurality of spaced aligned apertures 22 formed therethrough. An innermost member 28 is aligned in and adjacent to the outermost member 12. Additionally a plurality of spaced aligned elongated studs 40 are formed in the innermost member 28 in recesses 38 formed therein and aligned in a corresponding one of the apertures in the outermost member. The tire 10 further includes an air inflation member 36 for inflating the innermost member 28 so that the studs 40 formed thereon will move from a retracted recessed position to an extended position through the apertures in the outermost member 12 to provide additional surface traction for the tire.
Abstract:
A tire structure including an air passage disposed in the side wall of a tire between a flex region of the side wall and the upper most portion of the turnip, and a valve coupled to the air passage adapted to selectively control the flow of air through said passage.
Abstract:
A vehicle wheel with inflatable tyres, mounted on the same rim. One of the tyres (1), called a summer tyre, has tread suitable for summer use and at least one additional tyre (10), called a winter tyre, with a tread suitable for winter use. The winter tyre (or tyres) is mounted on the side of the summer tyre and is, in summer conditions, not fully inflated and hence not in contact with the road surface, because its circumference in its semi-inflated state has a shorter radius than that of the circumference of the summer tyre. The winter tyre (10) is securely attached to the outer surface of a concentric volume accumulator (7), which is part of the wheel rim and functions as a constantly available spare tyre. When inflated, the winter tyre (10) can expand, so that it has the same outer radius as the summer tyre (1) and thus also comes into contact with the road surface. After that, the pressure of the summer tyre is lowered and the area of contact with the road surface is redistributed to the winter tyre (or tyres).
Abstract:
A traction device for vehicle wheels comprises an expandable and contractible member (10) mounted next to a wheel (70) or in between dual wheels (12, 14). In another embodiment the device comprises an air chamber (106, 134) formed in the tread of the tire (120).
Abstract:
A self-contained anti-skid device to be used with a pneumatic tire (32) for boosting traction against slippery roadways covered with ice and snow while all designated characteristics of the tire against other road conditions are fully preserved, comprising: a plurality of projectable and retractable anti-skid pins (20) to be positioned radially at a tread (34) of the tire (32) for being projected from the tread (34), as often as required, when a plurality of expandable pneumatic chambers (26) adjacent to the pins (20) are pressurized using merely a fraction of the actual pressurized air of the tire (32). To retract the pins (20), air from the expandable pneumatic chambers (26) is released and preferably recycled back into the tire (32) through an air recycling device (64) implanted within the tread (34) and actuated by rotation of the tire (32) on a roadway. An air valve directs a flow of air from the tire (32) to the expandable pneumatic chambers (26) and therefrom preferably to an air recycling device. The air valve is controlled either manually (92) in the locality of the tire, remotely (100) within reach of a driver even while driving, or automatically (102), through a temperature sensing device implanted within the tread (34) as the tire (32) rotates over sporadically icy road conditions.
Abstract:
A tire structure includes bag-like members capable of expansion and contraction and which are buried in anti-slip grooves in the tire surface, and an air supply coupled to the bag-like members for supplying air to inflate the bag-like members to cause them to expand and project outwardly of the tire surface. The air supply may include stems coupled to an air source in the wheel part of the tire structure. Normally, the tire structure can be run as a usual tire. When running on a frozen road or the like, the tire structure permits functions and effects like a tire with a chain coupled thereto to be obtained by a simple operation to inflate and expand the bag-like members to cause them to project outwardly of the tire surface, and without need of any cumbersome operation of mounting a chain to the tire.
