Reformable Closure Device Strap

Abstract

Various mechanical closure systems and securing systems are disclosed, such as snowboard bindings and car rack systems. The systems include a mechanically reformable strap. The strap includes a wire disposed along a longitudinal axis of the strap. The wire maintains the strap in a desired geometry that is different from a previous geometry of the strap. In other embodiments, a wire-core strap can include transverse ridges, holes, or other types of grooves or apertures.

DETAILED DESCRIPTION

[0016] This document describes closure devices. In particular, this document describes a wire-core strap that is bendable from an original or enclosing geometry to a desired or opened geometry, enhancing the safety and ease of use of such closure devices. The embedded wire provides tensile strength and an ability to maintain a form or a bend into a desired geometry, and resists reforming the strap into its previous geometry without external influence. These straps can be embodied as ladder straps, also called ratchet straps, which can be used for mechanical closure systems in sports (bindings for snowboards, snowshoes, in-line roller skates, etc.), medical (orthotics, prosthetics, stabilization boots, spinal stabilizers, etc.), and transportation (car-top carrier systems or roof racks, etc.) applications. Other applications are possible and within the scope of this document.

[0017] FIG. 1 shows a snowboard binding 100 to illustrate one application of a closure device in accordance with embodiments herein. The snowboard binding 100 includes a rigid base 50, a rigid foot and heel support member 60 extending up from opposing sides of the base 50, and a pivotable back ankle support member 70 connected to the rigid foot and heel support member 60.

[0018] The snowboard binding 100 further includes one or more padded mechanical closure systems for enclosing a boot or foot of a user. Each mechanical closure system can include one or more ladder straps 102. Each ladder strap 102 includes a top side 104, at least a portion of which can have a number of transverse ridges that can be sequentially engaged by a locking tang of a ratcheting receptor 106. Each ladder strap 102 includes a wire (not shown), either embedded within the strap or disposed thereon, that allow the ladder straps 102 to be maintained in a geometry 103 that is different from a preformed geometry. Thus, the padded part of the mechanical closure system can also be held in an open position 101 as well, for easy ingress and egress of a boot into and out of the snowboard binding 100.

[0019] FIG. 2A shows a perspective view of a closure device 200 that is formed according to preferred embodiments described herein. FIG. 2B is a side view along the longitudinal axis L of the closure device 200, and FIG. 2C is a top-down view onto the top face 204 of the closure device 200. The closure device. 200. includes an elongated ladder strap 202 having a top face 204 that includes one or more transverse ridges 206. The transverse ridges 206 are for engaging with a tang of a ratcheting receptor. Alternative embodiments of a closure device 200 include a strap with a smooth top face 204, with any number of holes or grooves for engaging a receptor mechanism, as is described with reference to FIGS. 3A and 3B.

[0020] The ladder strap 202 may also include an aperture 208 that is preferably positioned and aligned in the middle of one end of the ladder strap 202. The ladder strap 202 can be any length, width or thickness, but must be formed of a material of such thickness and density so as to be bendable to various geometries. Preferably, the ladder strap 202 is longer in a longitudinal axis (L) than a transverse axis (I) so as to be elongated.

[0021] The closure device 200 further includes a wire 210 embedded within the ladder strap 202. In an exemplary embodiment, the wire 210 includes is a U-shaped metal wire having two parallel arms. The U-shaped metal wire can be positioned to at least partially circumscribe the aperture 208 for additional strength near the aperture 208, such that the arms extend in parallel along a major portion of a longitudinal axis L of the ladder strap 202. The wire 210 is adapted to maintain the ladder strap 202 in a desired geometry that is different from a previous geometry. For example, in a snowboard binding as shown in FIG. 1, the closure device 200 can be opened away from the base to allow a user easy and catch-free ingress into and egress from the binding.

[0022] FIGS. 3A and 3B illustrate alternative embodiments of a closure device 300 and 301, respectively. The closure devices 300 and 301 include a strap 302 having one or more holes 304 through the strap 302. The straps 302 are generally flat and elongated, but can be of any length, width or thickness. The holes 304 are preferably centered and uniformly spaced, and generally rounded. However, the holes 304 can be positioned anywhere within the strap 302, and may include an elongated slat 305 as shown in the strap 301 of FIG. 3B,

[0023] A geometry of the strap 302 is maintained by a wire 306 that is preferably embedded in the strap. The wire 306 can include generally parallel arms connected to a U-shaped portion 307 of the wire. The U-shaped portion 307 can be positioned at a periphery of one end of the strap, and may at least partially circumscribe an aperture 310 provided at that end, so as to provide further strengthening of the end of the strap.

[0024] FIG. 4 shows an inline skate 400 to illustrate yet another application of the closure devices described herein. The inline skate 400 includes a shoe 402 to receive a skater's foot, the shoe being mounted on a number of aligned wheels 404. The shoe can be enclosed around a skater's foot and ankle by engaging a ladder strap 406 into a receptor mechanism 408. When not so engaged, each ladder strap 406. includes a wire disposed along a longitudinal axis so that the strap can be bent outwardly and maintained in an open geometry as shown, so that a skater may insert or remove their foot without catching it on the ladder straps 406.

[0025] In preferred embodiments, each strap is formed of thermoplastic or thermoplastic polyurethanes that can withstand shock and adverse weather conditions and wild swings in temperature. In specific preferred embodiments, straps are formed of a thermoplastic polyester elastomer, such as Hytrel, to provide the flexibility of rubbers, the strength of plastics, and the processibility of thermoplastics. The straps can be made using any thermoplastic processes like injection molding, extrusion and meltcasting.

[0026] FIG. 5 illustrates one implementation of a carrier apparatus 500 that attaches to an automobile, for securing an item to the automobile. The carrier apparatus 500 includes one or more closure devices 502 coupled to the carrier apparatus 500 for securing the item received on the carrier apparatus 500.

[0027] Although a few embodiments have been described in detail above, other modifications are possible. For example, the wire may be bonded or otherwise attached to a surface of the strap, and need not necessarily be embedded within the core of the strap. Other embodiments may be within the scope of the following claims.
