DETAILED DESCRIPTION

[0037] The disclosed tie down strap assembly is described in detail with reference to the drawings, in which like reference numerals designate identical or corresponding elements in each of the several views. As used herein, the term “distal,” as is conventional, will refer to that portion of the device or component thereof which is farther from the user, while the term “proximal” will refer to that portion of the device or component thereof which is closer to the user. As used herein, the terms parallel and perpendicular are understood to include relative configurations that are substantially parallel and substantially perpendicular up to about + or −10 degrees from true parallel and true perpendicular. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the disclosure in unnecessary detail.

[0038] With reference to FIGS. 1 and 2, a tie down strap assembly in accordance with the disclosure is generally designated as 10. The tie down strap assembly 10 serves as a fastener to secure an object such as, e.g., cargo or equipment. In particular, the tie down strap assembly 10 is configured to adjustably provide a plurality of anchoring points to accommodate objects of various dimensions. The tie down strap assembly 10 includes hook assemblies 100 and a strap 500 in the form of, e.g., a flexible or elastic band. The hook assemblies 100 are detachably coupled to respective opposing ends of the strap 500. The hook assemblies 100 may be interlocked or nested to form a closed looped tie down strap assembly 10, as will be discussed below. Alternatively, the hook assembly 100 may securely engage a plurality of points on the strap 500 to form an anchoring point or a loop, as will be discussed below. It is envisioned that a plurality of tie down strap assemblies 10 may be utilized to form a longer tie down strap assembly 10. Specifically, the hook assemblies 100 of different tie down strap assemblies 10 may be interlocked to form a connection in tandem.

[0039] With reference to FIGS. 3-5, the hook assembly 100 includes an engaging portion 200 and a hook portion 300 extending from the engaging portion 200. The engaging portion 200 and the hook portion 300 are formed as a single construct. In an aspect, the hook assembly 100 may be monolithically formed. For example, the hook assembly 100 may be formed of a polymer. The engaging portion 200 includes opposing first and second sides 202, 204. The engaging portion 200 defines an opening 210 extending between the first and second sides 202, 204. The opening 210 is dimensioned to receive a portion of the strap 500 therethrough. In particular, the first side 202 includes a mouth 240 defining an aperture 242 dimensioned to receive at least a portion of the strap 500 therethrough. The aperture 242 is aligned with a central longitudinal axis defined by the hook assembly 100. The aperture 242 is configured to direct the portion of the strap 500 towards the opening 210. For example, the aperture 242 is oriented to provide a planar contact between the strap 500 and the first side 202. The second side 204 of the engaging portion 200 includes a boss 260 configured to secure the strap 500 thereto. Specifically, the boss 260 is received in a desired bore 550 (FIG. 12) of the strap 500. In particular, the boss 260 may define a groove 262 to further enhance securement of the strap 500 to the boss 260. The boss 260 and the aperture 242 of the mouth 240 may be in a superposed relation. The engaging portion 200 further includes a connecting wall 218 that is tapered or beveled to direct the strap 500 extending through the aperture 242 of the mouth 240 into the opening 210 such that the strap 500 wraps around the connecting wall 218 towards the boss 260 on the opposing side of the engaging portion 200.

[0040] With particular reference to FIGS. 4 and 5, the engaging portion 200 further defines a groove 220 in a peripheral portion of the engaging portion 200. In particular, the groove 220 partially surrounds the opening 210. The groove 220 has a radius of curvature complementary to a radius of curvature of the hook portion 300 such that a hook portion 300 of another hook assembly 100 may be received therein. For example, the groove 220 may detachably receive the hook portion 300 of another hook assembly 100 through, e.g., snap-fit configuration.

[0041] With reference to FIG. 6, the hook assemblies 100 at respective opposing ends of the strap 500 (not shown) may be interlocked or nested together. As shown in FIGS. 7-9, the hook portion 300 of one of the hook assembly 100 is received in the groove 220 of the engaging portion 200 of the other hook assembly 100 via snap-fit coupling.

[0042] With reference to FIGS. 10 and 11, two hook assemblies 100 may be interlocked by positioning the hook portions 300 in the corresponding grooves 220 and applying forces in the direction of arrows “X” to provide, e.g., a snap-fit, coupling. The interlocked hook assemblies 100 may be detached from each other through applying forces in the direction of arrows “Y”.

[0043] With reference now to FIGS. 12 and 13, the strap 500 is a flexible or elastic band that is configured to provide tension to enhance securement. The strap 500 includes opposing ends having respective loops 560. Each loop 560 is dimensioned to be received through the aperture 242 (FIG. 5) of the mouth 240 of the hook assembly 100. The strap 500 defines a plurality of bores 550 arranged along a length of the strap 500. Each bore 550 is dimensioned to receive the boss 260 (FIG. 4) of the hook assembly 100 or a tip 310 (FIG. 3) of the hook portion 300, as will be discussed below. Under such a configuration, an anchor point may be selectively chosen to accommodate various dimensions of the object to be secured or fastened.

[0044] With reference to FIG. 14, in use, the opposing ends of the strap 500 are interlocked and the length of the strap 500 is adjusted by securing the bosses 260 of the hook assemblies 100 to the desired bores 550 of the strap 500. Specifically, the loop 560 of the strap 500 is received through the aperture 242 (FIG. 5) of the mouth 240 of the corresponding hook assembly 100 and through the opening (FIG. 3). Thereafter, the length of the strap 500 is adjusted through selecting the bore 550 that will provide adequate tension in the strap 500. Alternatively, the strap 500 may also extend through the loop 560, as shown in FIG. 15, to further enhance securement of the strap 500 with the hook assembly 100.

[0045] While it has been shown to form a closed loop by interlocking the hook assemblies 100 to each other, the hook portion 300 may be directly secured to the strap 500. Specifically, as shown in FIGS. 16 and 17, the tip 310 of the hook portion 300 of the hook assembly 100 may be received through a bore 550 of the strap 500 to form a desired closed loop. In this manner, the tie down strap assembly 10 may fasten an object, as shown in FIG. 18.

[0046] In another aspect, the tie down strap assembly 10 may be used with only a single hook assembly 100. With reference to FIGS. 19 and 20, one end of the tie down strap assembly 10 may be used without the hook assembly 100. The one end with the loop 560 may form a loop by looping the strap 500 through the loop 560 around an object “O”. With reference to FIG. 21, it is further contemplated that the tie down strap assembly 10 may be lengthened through use of additional tie down strap assembly 100. Specifically, hook assemblies 100 of two tie down strap assemblies 10 may be interlocked in a manner described above to connect the two tie down strap assemblies 10 in tandem.

[0047] Any of the components described herein may be fabricated from either metals, plastics, resins, composites, or the like taking into consideration strength, durability, wearability, weight, resistance to corrosion, ease of manufacturing, cost of manufacturing, and the like. It should be understood that various aspects disclosed herein may be combined in different combinations than the combinations specifically presented in the description and accompanying drawings. It should also be understood that, depending on the example, certain acts or events of any of the processes or methods described herein may be performed in a different sequence, may be added, merged, or left out altogether (e.g., all described acts or events may not be necessary to carry out the techniques).

[0048] It will be understood that various modifications may be made to the disclosed tie down strap assembly. Therefore, the above description should not be construed as limiting, but merely as exemplifications of the disclosure. Those skilled in the art will envision other modifications within the scope and spirit of the disclosure.
