Patent number: 6898826Abstract: A ladder strap (150) is made by joining—for example, by co-molding—a first, relatively supple material, defining a lower strap portion (155) with a second, relatively hard material defining an upper strap portion (165). The teeth (167) of the ladder strap are comprises substantially of the harder, second material. In a preferred embodiment, the first and second materials are thermoplastic urethanes, and the co-molding is done using an injection molding process. The co-molding process may be accomplished with co-injection, wherein the two materials are injected at about the same time, or the first material may be injected into a first mold cavity and allowed to partially set, after which the cavity is modified to accommodate the second material.Type: GrantFiled: January 6, 2003Date of Patent: May 31, 2005Assignee: K-2 CorporationInventors: Alexander D.

Patent number: 6889407Abstract: A cord lock apparatus (100) is disclosed comprising a base (120) having a converging channel (128), and an elastically flexible locking insert (140) that is retained by the base. The locking insert defines a loop including left and right legs (146) that are generally parallel to the sidewalls (124) of the channel, and receive a cord (102) therebetween. When the locking insert is undeformed, the cord is clampingly engaged between the insert legs and the base sidewalls. The user pulls upwardly on the loop to elastically deform the insert such that the legs rotate inwardly, releasing the cord. The insert may also slide longitudinally to a limited extent in the channel. Teeth (123, 143) may be provided on the locking insert and/or the base to more securely engage the cord.Type: GrantFiled: June 10, 2003Date of Patent: May 10, 2005Assignee: K-2 CorporationInventor: John Dietrich Martin
