036032000 | Rubber | 11 |
20090049717 | PNEUMATIC TIRE, SHOE, TIRE CHAIN, AND PNEUMATIC TIRE VULCANIZATION-MOLD - The pneumatic tire according to the present invention has a roughness profile skewness (Rsk) of zero or greater on land portion surfaces | 02-26-2009 |
20100139128 | ZINC IONOMER RUBBER ACTIVATOR - Curable rubber compositions and cured articles are based on the use of zinc activator compositions for the sulfur cure. Activator compositions contain zinc and a polymeric component having a plurality of COOH groups, at least some of which are neutralized with the zinc. With polymeric zinc activators, sulfur cure can be activated at levels of zinc below those used in conventional systems. | 06-10-2010 |
20100263240 | SHOE SOLE AND METHOD - A shoe outsole and method of manufacture wherein the outsole is formed using recycled rubber granules generated during the shoe manufacturing process, the recycled rubber granules being used as a filler material and being mixed with various thermoplastic materials or vulcanized rubber to form the shoe outsole. The recycled rubber granules are mixed with the thermoplastic material or vulcanized rubber to form a filled elastomer which includes at least 50% by weight of a virgin thermoplastic material and no more than about 30% by weight of the recycled rubber granules. | 10-21-2010 |
20110126432 | Combined Shoe - A combined shoe formed by a selected vamps and soles with different functions and appearances at any time, comprises a sole, a vamp and attaching means used to quick-connect the vamp and the sole for forming a whole shoe. The attaching means includes a front cap located in front of the sole for buckling the tip of the vamp; a hind cap located in the hind of the sole for buckling the heel of the vamp; two pairs of matched anti-slide plates located in half-soles/heels of both vamp and sole for preventing relative sliding between the vamp and the sole; and a plurality of pressing means used for pressing the vamp on the sole tightly. The combined shoes provide a multitude of combinations and reduce the shoe purchasing cost. Since the vamp and the sole can be disassembled and assembles quickly, when the wearer enters a room, he needs only remove the sole for keeping the cleanliness of the room and still can keep his feet warm and/or prevent the diffusion of foot odor. | 06-02-2011 |
20110258886 | Slip-Resistant Rubber Composition, Outsole Using the Rubber Composition and Method of Manufacturing the Outsole - Disclosed is a slip-resistant rubber composition, which includes a substrate made of rubber, about 0.5 to about 3 parts by weight of a vulcanizer, about 2 to about 5 parts by weight of glass fibers, and about 1 to about 100 parts by weight of an additive, based on 100 parts by weight of the substrate, and has remarkably improved non-slip properties. Also, an outsole using the slip-resistant rubber composition and a method of manufacturing the outsole are provided, in which the outsole which results from subjecting the slip-resistant rubber composition to cutting, arrangement and vulcanization molding and in which one-side ends of the glass fibers are located at the lower surface of the outsole may exhibit remarkably improved non-slip properties so that a user who is wearing shoes having such an outsole is able to walk even on inclined ice. | 10-27-2011 |
20120066938 | SHOE SOLES FOR ENHANCING GRIPPING WITH A SMOOTH HARD SURFACE - Shoe soles with and without removable/replaceable gripping pods for athletic or sport shoes are provided with enhanced traction. The sole portions or gripping pods may be provided with a supply of a substance that exhibits a tackiness for enhancing friction between the shoe sole and the any hard floor. The tackiness-enhancing substance may be time-released or discharged from within the shoe sole onto the lower surface(s) of the sole that make(s) contact with the smooth hard playing surface or may be in response to compression or shear forces acting on the sole during play to prolong the tacky properties and reduce slippage. A visual indicator may be provided for notifying the player that it is time to replace the worn or used pod and insert a fresh pod or insert into the pod(s) to maintain high levels of gripping. | 03-22-2012 |
20120180344 | Footwear Outsole - An outsole for an article of footwear. The outsole includes an outsole body having a ground contact surface and defining grooves having a sinusoidal path along the ground contact surface. The grooves are arranged to provide an edge density of between about 40 mm/cm2 and about 200 mm/cm2 and a surface contact ratio of between about 40% and about 95%. | 07-19-2012 |
20120260535 | Outsole with Extendable Traction Elements - An outsole element may includes a first side configured for attachment to a midsole or other shoe component and an exposed second side opposite the first side. A plurality of recesses can be formed in the second side. Each of those recesses may include a concave region aligned with a corresponding raised region located on the first side and may further include a corresponding traction element. | 10-18-2012 |
20120304503 | OUTER SOLE OF A CLIMBING SHOE - Outer sole of a climbing shoe made of a flexible natural or synthetic rubber material having the general appearance of a smooth surface, the outer sole including at least in the zone located in its front portion, grooves produced by etching. | 12-06-2012 |
20130008059 | SPORT SHOE OUTSOLE WITH ANTI-SLIP AND ANTI-ABRASION - The Present invention is directed to an anti-slip, wear-resistant sports shoe sole principally composed of a sole pad and a bottom cushion layer bonded to the bottom of said sole pad. The bottom cushion layer is composed of two parts, namely a soft under-cushion running inward from the front of the sole, and a hard under-cushion positioned at the heel and front of foot areas. The triangular area in the specially inclined underside design of the sports shoe sole, made of a low-density (soft) rubber material, includes a number of point-shaped protrusions clustered together to facilitate turns and twisting motions, while helping to prevent slipping, aid precision and increase comfort. Other than the triangular area, the whole of the underside of the heel and front of foot areas are made using a solid (hard) rubber material which is effective in terms of its anti-slip, wear-resistant properties. | 01-10-2013 |
20140033578 | COMBINED LEATHER-RUBBER MOLDED OUTSOLE SYSTEM AND METHOD - Systems and methods are involved with but are not limited to: placing one or more leather portions in a mold, the mold including a cavity with a cavity shape; placing rubber material in the mold; and applying heat to the one or more leather portions and the rubber material while the one or more leather portions and the rubber material are in the mold and subsequently cooling the one or more leather portions and the rubber material thereby fusing one or more portions of the rubber material to the one or more leather portions and thereby conforming one or more portions of the rubber material to one or more portions of the cavity shape. In addition to the foregoing, other method aspects are described in the claims, drawings, and text forming a part of the present disclosure. | 02-06-2014 |
