The present disclosure relates to strap-type connector systems for releasably securing pocket members, pouches, holsters, or other articles onto supporting articles such as backpacks, luggage, jackets, vests, garments, or other supporting structures, and more particularly to such strap attachment arrangements that releasably secure a removable first article to a supporting second article by interweaving individual, flexible strap member components secured to the first or second articles.
Previous strap-type attachment apparatuses and fastening systems for releasably securing an article to a supporting article have been discussed in U.S. Patent Application Pub. No. 2007/0158380 of Calkin. Strap-type attachment arrangements are desirable because they provide an extremely strong yet flexible attachment for various pocket-type members onto garments or articles worn or carried by persons such as military personnel, emergency and rescue personnel, hunters, anglers, or climbers, to name just a few examples. Removable articles in the form of pocket members or pouches are used to hold handguns, ammunition clips, grenades, medical supplies, canteens, and many other types of supplies or gear suited for particular field functions. The strap-type attachment arrangements are modular systems that permit removal and exchange of alternate sizes, types, or arrangements of the pouch members as may be desired, as well as permitting the desired repositioning of the pocket members on the supporting article to suit the purpose of the wearer. In combat or in other emergencies, slow, confusing, or cumbersome removal of the pouches can present serious problems for the user, particularly when speed and simplicity are imperative for the user's safety or the safety of others.
A releasable connector strap system for releasably securing a removable strap-type attachment article to a support strap-type structure, which includes spaced apart and elongated connector strap segments anchored to one side of the removable strap-type attachment article, and a pull handle segment affixed to a distal end of the elongated connector strap segments, proximal to the one side of the removable strap-type attachment article. In another embodiment, a retaining pouch is positioned to receive and releasably retain terminal ends of the connector strap segments, for retaining the terminal ends when the connector strap segments interlock the support strap-type structure to the removable strap-type attachment article.
Additional aspects and advantages will be apparent from the following detailed description of preferred embodiments, which proceeds with reference to the accompanying drawings.
For purposes of clarity and ease of description, opposing surfaces of example quick-release strap-type attachment articles discussed below include top and bottom, face and rear, and hinge-side and entry-side surfaces. The terms “top” and “bottom” of a removable strap-type attachment article (or simply “article”) correspond to lateral surfaces that are parallel to the ground when the article is secured to an upright support structure, such that the top surface is farthest from the ground. The “face” and “rear” of a strap-type attachment article correspond to the respective exposed and concealable major longitudinal surfaces, with the concealable surface including an interlocking system of webbing described below. The hinge-side and entry-side surfaces include the two remaining opposing longitudinal surfaces that may be perpendicular to the ground. Skilled persons will recognize that the designations of these surfaces are arbitrary and are simply intended to facilitate a frame of reference for the examples of strap-type attachment articles discussed below. In other words, the article may be attached in any orientation, e.g., with the lateral and longitudinal sides transposed, or the entry- and hinge-sides may correspond to the top and bottom the article. Related parts discussed herein share identical reference numbers.
Referring to the embodiment shown in
The base surface 10 includes a plurality of laterally extending, laterally elongated securement straps 14a-14c (collectively, 14) secured to the base surface 10 by suitable means such as by sewing or stitching 16. The securement straps (or web members) 14 are formed of flexible, lightweight material such as nylon webbing material that is well known for its strength, durability, and resistance to wear or breaking. In some embodiments, other suitable fabric materials may be used for the securement straps 14. Although three securement straps 14a-14c are depicted on the fragment of the base surface 10, a greater or fewer number of the securement straps 14 are possible.
Each of the laterally extending securement straps 14a-14c is arranged on the underlying base surface 10 in a longitudinally spaced apart manner having spaces 18a-18c (collectively, 18) therebetween. The longitudinal spaces 18a-18c have widths approximately equal to the widths of the securement straps 14a-14c, although various securement strap widths and longitudinal space widths are contemplated and within the scope of the present disclosure, e.g., unequal or variable widths. According to one embodiment, longitudinal spaces 18 are sufficiently wide to accommodate confronting securement straps of various removable articles in accordance with the Pouch Attachment Ladder System (PALS).
The securement straps 14 are secured on the base surface 10 by sewing or stitching 16 in a looped manner that provides at least one longitudinally aligned column of open loops or securement loop channels 20j (collectively, 20), where subscript j denotes a particular channel column, i.e., 1-7 in the example support article 8. Individual loops are identified by an additional reference letter (a, b, or c) to indicate the corresponding securement strap 14a, 14b, or 14c. For example, the first column of open loops (or loop channel) 201 is identified by a dotted line and includes loops 20a1, 20b1, and 20c1; the second column 202 includes loops 20a2, 20b2, and 20c2; and so on. Skilled persons will recognize that the width of the loop channels 20, as well as the distance between adjacent loop channels, may vary and may depend on the particular field use of the bag 12. Furthermore, a loop means a structure—alone or in combination with another structure—that enfolds or encircles an aperture.
With reference to
The securement straps 34 are positioned on the bag 12 so that when the rear attachment surface 30 confronts the base surface 10, the securement straps 34 generally confront the corresponding spaces 18, and the securement straps 14 generally confront the corresponding spaces 38. For example, the securement strap 34a aligns and confronts with the base surface 10 in the space 18a; the securement strap 14b aligns and confronts with the rear attachment surface 30 in the space 38a; and so on. The securement strap 14a aligns and confronts a laterally elongated webbing backing 39 that is stitched into the rear attachment surface 30 adjacent to the securement strap 34a. The webbing backing 39 provides additional thickness that helps to maintain a tight connection between the initial securement strap 14a and the bag 12 (as depicted in
The bag 12 of the illustrated embodiment is attached to a base surface 10 having six or more securement straps 14, i.e., a securement strap 14a to align with the webbing backing 39, and five other securement straps 14 to align with each of the spaces 38a-38e. However, skilled persons will recognize that the bag 12 may be attached to a base surface 10 having fewer than six securement straps. For example, the three securement straps 14a-14c may be provided to align with intermediate spaces 38b-38d. In another embodiment, two securement straps (not shown) may be provided to align with the end-most spaces 38a and 38e. In other words, the total number and position of the securement straps 14 or 34 may vary.
Similar to the securement straps 14 of the support article 8, the securement straps 34 of the bag 12 also provide open loops aligned to form loop channels 40. As described below with respect to
Although occluded in
As shown in
The position of the retaining member 64 relative to the longitudinally end-most securement strap 34g helps develop the angle of the folds 56a and 56b, and thereby imparts the raised elbows 60a and 60b when the terminal ends 54a and 54b are tucked into the respective side openings 62a and 62b of the retaining member 64. In addition, the securement straps 34g and 34f are adjacent, i.e., without any intermediate space, such that a partial loop channel formed by loops 40g1, 40f1 is two times the longitudinal length of the channel segments formed by other loops. The placement and dimensions of the retaining member 64 forming the raised elbows 60a and 60b, in conjunction with the longer loop channels formed by securement straps 34g and 34f, help to prevent the connector straps 41a and 41b from inadvertently loosening. Nevertheless, the connector straps 41a and 41b are not so restricted as to prevent quick release of multiple straps, i.e., unweaving or disengaging the connector straps 41a and 41b from the securement straps 14 and 34 by a strong pull, as discussed in detail below.
Skilled persons will recognize that various retaining member 64 placements or attachments are possible. For example, in another embodiment (not shown), a retaining member 64 can be riveted directly over the securement strap 34g, thereby imparting a fold with an included angle between adjacent segments, wherein the included angle is less than 90°. Increasingly acute included angles are potentially less susceptible to loosening but potentially more resilient to release. Conversely, in yet another embodiment, the retaining member 64 may be affixed to a lateral side surface of the bag 12 or the support article 8, or each connector strap 41a and 41b may have an individual retaining member (not shown). A separately dedicated retaining member is optional, and instead the terminal ends 54a and 54b may be tucked into securement loops on the support article 8, as described in U.S. Patent Application Pub. No. 2007/0158380 of Calkin, which is assigned to the applicant of the present disclosure.
Various flexible strap-type arrangements and interlocking strap attachment systems have been attempted. Applicants discovered that the previous attempts failed to provide an intuitive and efficient detachment mechanism capable of quickly releasing an attached article. For example, U.S. Pat. No. 5,259,093 of D'Annunzio for Strap Connector discusses a quick-release tab for a single connector strap that requires pulling the tab and the attached article in opposite directions, thereby requiring at least two steps to release a single connector strap. In previous attempts featuring multiple connector straps, each connector strap functioned more or less independently such that each connector strap had to be pulled individually to release an attached article from a support structure. As described below, applicant discovered that a third strap segment (or pull handle segment) 69, joining pullable end portions of the connector straps 41a and 41b may be used to form a quick-release pull handle for the connector straps 41, thereby allowing multiple connector straps to be readily released simultaneously.

According to the embodiment of
The fasteners 50a and 50b retain connector strap assembly 70 to the bag 72. In another embodiment (not shown), the connector strap assembly 70 may be constructed from a single, untethered length of fabric, woven through loop channels as described above with respect to
In the example shown in
With reference to
The relative lengths of the connector strap segments A, B, and C are selected so that when the connector straps 71a and 71b are interwoven, the pull handle segment 69 is readily graspable and the terminal ends 54a and 54b may be removed from the interlaced ladder of the securement straps 14 and 34 to release the bag 72 with a strong pull in a direction transverse to the plane of the top surface panel 80. Thus, the connector strap segments A, B, and C may vary depending on the following three criteria. First, the stitching 90a is positioned along the connector strap 71a such that the connector strap segments A and C that define the subsegment 74a have a cumulative length (A+C) that is greater than a distance D between the attached end 97a and the bottom-side 65 of the securement strap 34g (i.e., A+C>D). As described above, the length of the subsegment 74a permits the terminal end 54a to extend past the bottom-side 65 for positioning in the retaining member 64. Second, the stitching 90a is positioned along the connector strap 71a such that the connector strap segments B and C that define the subsegment 76a have a cumulative length (B+C) that is greater than a distance E between the two farthest sides of the securement straps 34a and 34g (i.e., B+C>E). The length of the subsegment 76a helps provide a readily graspable pull handle segment 69 that extends beyond a top-side 100 of the securement strap 34a when the connector strap 71a is interwoven. Third, the location of the attached end 97a and the top-side 100 of the securement strap 34a define a distance F therebetween. The connector strap segment A and the distance F have a cumulative length (A+F) that is approximately equal to or greater than a length C (i.e., A+F≧C) so that the terminal end 54a may be withdrawn and pulled beyond the top-side 100 of the securement strap 34a. In a typical embodiment, A>>F and C>>F, so therefore A≧C. The interrelation of the connector strap segments A, B, and C and the various interstrap distances D, E, and F can be expressed according to the following three equations:
In one embodiment (not shown), an additional stiffening layer may be inserted between layers of the connector straps 71a and 71b. In some embodiments, the stiffening layer may be stitched on an exterior surface of connector straps 71a and 71b as discussed with respect to
To prevent snagging of the terminal ends 118a and 118b and to provide a means to quickly release the connector straps 119a and 119b, the pairs of subsegments 74a, 76a and 74b, 76b are covered with a cover assembly 120. The cover assembly 120 includes cover strip segments 122a and 122b, and the pull handle segment 69 interposed therebetween. The cover assembly 120 and the connector straps 119a and 119b form a strap assembly 124. Terminal ends 126a and 126b of respective cover strip segments 122a and 122b are heat cut (i.e., melted and rehardened) and aligned with terminal ends 54a and 54b so that the rehardened portions ease insertion of connector straps 119a and 119b into loop channels. The cover strips 122a and 122b are attached to the underlying pairs of subsegments 74a, 76a and 74b, 76b with the respective stitching 90a and 90b, forming connector strap segments similar to the connector strap segments A, B, and C described previously.
