| 20080271341 | Sole Arrangement and Shoe - The invention concerns a sole arrangement ( | 11-06-2008 |
| 20090193681 | Universal Antislip Claw for Footwear - Accidental falls are one of the principal causes of disability. The present invention relates generally to a device that may be fit in footwear to prevent injuries caused by slippery terrain. The device is provided with retractable spikes which penetrate the ice or slippery surface like a claw. The device also has an excenter system which allows adjustment of the spikes between two positions. | 08-06-2009 |
| 20100077635 | ARTICLES WITH RETRACTABLE TRACTION ELEMENTS - Articles of manufacture and articles of wear may include one or more retractable traction elements. A plurality of the retractable traction elements may be interconnected by a base member and may form an insert. Each of the retractable traction elements may include an extension inducing element and a ground (or other surface) contacting element. The extension inducing element may flex in response to an applied force and may cause the ground or other surface contacting element to extend and engage an underlying surface. | 04-01-2010 |
| 20110126426 | Spike Device For An Anti-Slid Shoe - The invention concerns a spike device ( | 06-02-2011 |
| 20110162235 | FOOTWEAR WITH RETRACTABLE SPIKES - An apparatus for selectively extending and retracting spikes includes spike actuating assemblies mounted to, and cooperating between, a first plate and a first slider frame, and a second plate and a second slider frame, pivotally mounted to the first plate and first slider frame respectively. Each spike actuating assembly contains a spike. The first slider frame is translatable to actuate the spike actuating assemblies to thereby extend and retract the spikes from the spike actuating assemblies. A cyclically alternating positioner is mounted on the first plate for moving the first and second slider frames relative to the first and second plates. The positioner has only a single actuating button adjacent the heel. Depressing the actuating button a first time causes the positioner to move the slider frames to extend the spikes. Depressing the actuating button a second time causes the positioner to move the slider frames to retract the spikes. | 07-07-2011 |
| 20110203136 | SELF-ADJUSTING STUDS - Articles of footwear may include self-adjusting studs that adjust to various types of conditions, environmental changes, and applied forces. The self-adjusting studs may have a first portion and a second portion of different levels of compressibilities and/or retractabilities that compress and extend based on the type of surface on which the wearer is walking or running. This footwear with self-adjusting studs may easily transition between surfaces of varying hardness without causing damage to the surface, but also providing the wearer with the necessary amount of traction on each type of surface. Wearers will enjoy the benefit of being able to move on various surfaces without the need to change their footwear multiple times to accommodate the wearer's varying traction needs on different surfaces. | 08-25-2011 |
| 20130239437 | Rigid Cantilevered Stud - Articles of footwear may include selectively engageable traction elements that engage with a surface or the ground during certain activities and do not engage with the surface or the ground during other activities. The selectively engageable traction elements are caused to engage with the ground or surface when a portion of the footwear is flexed. When the footwear is in its unflexed position, the selectively engageable traction elements may not engage with the ground or surface. Selectively engageable fraction elements may be desired or may be useful during particular, targeted movements such as sharp turns, pivoting, sudden or abrupt starting and stopping motions, and the like and in changing environmental conditions, such as on various surfaces having different characteristics. Wearers of such footwear may benefit from the extra traction provided by the selectively engageable traction elements when performing the targeted movements and/or when wearing the footwear on surfaces with varying conditions. | 09-19-2013 |
| 20140101970 | Replaceable Traction Cleat for Footwear - Adjustable traction is provided in a traction cleat by selectively restricting or not the amount of flexure permitted for a dynamic traction element on the cleat. Restricting flexure is alternatively achieved by an adjustably positionable ring or by rotating the cleat to align the dynamic element with different shoe sole topographical features. A dual locking post is provided to reduce the surface area required on the cleat hub for locking structures. The cleat is formed in a two shot molding process that permits elongations of the dynamic traction elements without sacrificing the integrity of the cleat structure. | 04-17-2014 |
| 20140165423 | Traction Cleat and Receptacle - A traction cleat applicable for use in field sports is provided with dynamic traction elements having larger radial thickness, cross-sectional area and mass than dynamic elements in golf shoe cleats. The strength of a locking arrangement for the cleat in a shoe-mounted receptacle is enhanced by providing an annular array of spaced locking stubs on the receptacle to engage a similar array of spaced locking posts on the cleat. | 06-19-2014 |
| 20150059207 | ANTI-SLIP DEVICE HAVING RETRACTABLE SPIKES - A device for slip-damping effect, comprising a sole unit and a spike with a resilient, circumferential fastening which allows the spike to be tilted in case of shearing motion against the ground surface, wherein the device provides grip on hard ground surfaces as a result of the sole unit, and at the same time the risk of slipping on hard, slippery ground surfaces is reduced by the spike. | 03-05-2015 |
| 20150296926 | ANTI-SLIP MECHANISM FOR FOOTWEAR THEREOF - A footwear including a retractable anti-slip mechanism is presented, the anti-slip mechanism comprising at least one retractable ground-engaging member disposed in a sole of the footwear and pivotally connected to a pivot member extending on a side of the footwear for selectively expanding the at least one retractable ground-engaging members under the sole to engage with the ground and retracting the at least one retractable ground-engaging members in the sole to prevent engaging the ground. | 10-22-2015 |
| 20150305445 | FOOTWEAR WITH RETRACTABLE SPIKES - An apparatus for selectively extending and retracting spikes includes spike actuating assemblies mounted to, and cooperating between, a first plate and a first slider frame, and a second plate and a second slider frame, pivotally mounted to the first plate and first slider frame respectively. Each spike actuating assembly contains a spike. The first slider frame is translatable to actuate the spike actuating assemblies to thereby extend and retract the spikes from the spike actuating assemblies. A cyclically alternating positioner is mounted on the first plate for moving the first and second slider frames relative to the first and second plates. The positioner has only a single actuating button adjacent the heel. Depressing the actuating button a first time causes the positioner to move the slider frames to extend the spikes. Depressing the actuating button a second time causes the positioner to move the slider frames to retract the spikes. | 10-29-2015 |
