No. 12/931,111 filed Jan. 25, 2011 entitled “Magnetic Hook And Loop Interface”, having a common applicant herewith, which claims priority from U.S. Provisional Patent Application having Ser.

FIELD OF THE DISCLOSURE
The disclosures made herein relate generally to fastening devices and, more particularly, to fastening devices having mating surfaces with interlocking engagement structures.
BACKGROUND
Various types of hook and loop fastening devices (e.g., Velcro brand hook and loop fastener) are well known. Such fasteners include a first material having a surface covered with hook engagement structures and a second material having a surface covered with loop engagement structures. When such hook and loop engagement structures are brought into contact with each other they become mechanically engaged with (i.e., interlocked with) each other thereby securing the first material to the second material. Separation of the two materials is performed by physically peeling them apart from each other. As such hook and loop fasteners provide a low-cost yet very effective means for securing two different objects together in a readily releasable manner.
Although hook and loop fasteners provide a low-cost and effective means for securing two different objects together in a readily releasable manner, there exist a number of shortcomings for using this type of fastening device in certain applications. One such shortcoming relates to using hook and loop fasteners in applications where the user desires to remain quiet. However, separation of the hook material from the loop material produces considerable noise. For example, in a combat or law enforcement situation, separation of the hook material from the loop material by a law enforcement or military personnel (e.g., such as when opening a pouch to retrieve a piece of equipment contained therein) can undesirably reveal their physical location. Similarly, such noise would be undesirable/adverse to a hunter while hunting or to a person otherwise engaged in an activity where such noise is undesirable/adverse. Another such shortcoming is that hook and loop material can become worn or contaminated over time, thereby reducing its effectiveness as a closure mechanism.
Therefore, a magnetic interface system that mounts between mating surfaces of a hook and loop fastener for inhibiting engagement of the hook engagement structure with the loop engagement structure and that thereby enables the magnetic interface system to provide selective engagement of two objects to which the hook and loop engagement structures are respectively attached would be advantageous, desirable and useful in that it overcomes shortcomings associated with conventional implementations of hook and loop fasteners.

As best shown in FIGS. 1 and 5, the magnet 110 is retaining at a desired position (e.g., a central area) of the hook-carrying interface patch 100 by a retaining border 116 encompassing the magnet 110. Examples of means for retaining the magnet 110 in such desired position include, but are not limited to, stitching with thread, ultrasonic welding, laser welding, adhesive bonding, and the like.
Referring to FIGS. 2 and 4, the loop-carrying interface patch 102 has a first major surface 118 and a second major surface 112 opposite the first major surface 118. Loop engagement structures 122 extend from the first major surface 118 of the loop-carrying interface patch 102. The loop engagement structures 108 are an example of interlock structures of a first configuration. The loop-carrying interface patch 102 has a magnet 124 (i.e., a magnetic element) embedded within the loop-carrying interface patch 102 between the first and second major surfaces 118, 120. Optionally, where the hook-carrying interface patch 100 includes the magnet 110, an element to which a magnet is attracted (e.g., a disk or plate made from a ferrous material (e.g., steel)) can be used in place of the magnet 124.

It is disclosed herein that additional layers of material (e.g., a stiffening layer) can be disposed between the first and second layers of material 126, 128. Such additional layers of material can be secured to the first layer of material 126 and/or the second layer of material 128 by means such as, for example, stitching with thread, ultrasonic welding, laser welding, adhesive bonding, and the like.
The magnet 124 is disposed between the first and second layers of material 126, 128 of the loop-carrying interface patch 102. As best shown in FIGS. 1 and 5, the magnet 124 is retaining at a desired position (e.g., a central area) of the loop-carrying interface patch 102 by a retaining border 130 encompassing the magnet 124. Examples of means for retaining the magnet 124 in such desired position include, but are not limited to, stitching with thread, ultrasonic welding, laser welding, adhesive bonding, and the like.
In view of the preceding disclosure, a skilled person will appreciate that the hook-carrying interface patch 100 can have the hook engagement structures 108 mechanically engagable with and separable from loop engagement structures of an article (e.g., a prior art storage implement such as a pouch having a hook and loop closure structure) and the hook-carrying interface patch 100 can similarly have the loop engagement structures 122 mechanically engagable with and separable from hook engagement structures of the article. In this manner, the article can temporarily or permanently be converted from having a hook and loop engagement structure (e.g., closure structure) to having a magnetic engagement structure (e.g., closure mechanism). Specifically, during use, the magnetic element of the hook-carrying interface patch 100 is engagable with and separable from the magnetic element of the loop-carrying interface patch 102 while the hook engagement structure 108 and the loop-engagement structure 122 both remain engaged with their respective engagement structure of the article (i.e., force required to separate the magnetic elements is less than the force required to separate the hook and loop interfaces). Preferably, the first and second interface patches 100, 102 are sized to prevent hook and loop engagement structures of the article from coming into contact with each other when the magnetic elements of the interface patches 100, 102 are brought into contact with each other.
