TECHNICAL FIELD
The example embodiments of the present invention generally pertain to straps, and more particularly to adjustable straps.
BACKGROUND
Straps, such as a cinching strap, are frequently used to secure bundled and coiled objects together. While cinching straps presently exist to secure bundled or coiled objects, these straps are frequently “one size fits all.” With the one size fits all strap, the strap is always just a little too big. As a result there will always be excess strap ends to deal with. In some straps the loose end gets rolled around a wheel as the strap is ratcheted tight, which takes time to roll when cinching the strap and takes time to unroll when releasing. Other systems simply leave it to the user to figure out what to do with the excess straps. What is needed is an adjustable strap assembly that allows the user to quickly and easily set the length of the strap to fit the desired bundle to be cinched while eliminating the excess strap ends.
BRIEF SUMMARY
According to one exemplary embodiment of the present invention, an adjustable strap assembly comprises a cincture and a band. The cincture and the band preferably include attachment components on end and are adjustably connected such that the overall length of the strap assembly can vary in length from as little as approximately just the length of the cincture to as long as approximately the length of the cincture and band together. In addition the embodiments may include a securing mechanism to maintain the adjustable strap assembly at the desired length even under stress. In one embodiment the band is made from elastic material to ensure that when the adjustable strap assembly is used to cinch a bundle, the adjustable strap assembly will remain tight.

The adjustable strap assembly 100 depicted in FIG. 1, includes a cincture 1102 and a band 1202. Depending on the application, either or both the cincture 1102 or the band 1202 may be fabricated using a sturdy elastic material, such as preferably a polyester webbing material, to allow sizes, such as the length, of the cincture 1102 or the band 1202 to expand and keep whatever is being secured is firmly retained. Of course only part or all of the cincture 1102 or the band 1202 may be made from a sturdy elastic material. FIGS. 2 and 3 illustrate a front view and a side view of the cincture 1102 of the adjustable strap assembly 100. FIGS. 4 and 5 illustrate a front view and a side view of the band 1202 of the adjustable strap assembly 100. The cincture 1102 may have a cincture adjusting end 1104 and a cincture fastening end 1106 (shown in FIGS. 1-3). The band 1202 may have a band adjusting end 1204 and a band fastening end 1206 (shown in FIGS. 1, 4 and 5).
Referring back to FIG. 1, the adjustable strap assembly 100 may comprise an adjustment mechanism 101. In one embodiment, the adjustment mechanism 101 may be configured to adjust the overall length of the adjustable strap assembly 100. The adjustment mechanism depicted in FIG. 1 holds the cincture and/or band in place in accordance with the desired overall length of the adjustable strap assembly 100. In FIG. 1, the adjustment mechanism 101 comprises a first sleeve 1108 configured to be attached to the cincture adjusting end 1104 and a second sleeve 1208 configured to be attached to the band adjusting end 1204. The first sleeve 1108 and the second sleeve 1208 may be attached to the cincture 1102 and the band 1202 by one of sewing, glue, adhesive or Velcro or other convenient method of securing.
The adjustable strap assembly 100 may also comprise a fastening mechanism configured to fasten the cincture fastening end 1106 and the band fastening end 1206. The fastening mechanism may comprise a first fastening element configured to be attached to the cincture fastening end 1106 and a second fastening element configured to be attached to the band fastening end 1206. One of the first and second fastening elements is held by the other in a secure manner. For example, the fastening mechanism may be a snap buckle, as shown in FIG. 1, including a male fastening element 1110 attached to the cincture fastening end 1106 and a female fastening element 1210 attached to the band fastening end 1206. The male fastening element 1110 may be held by the female fastening element 1210 in a secure manner. The fastening mechanism may comprise two clasps attached to the cincture and band fastening ends respectively. By holding one clasp in the other, the cincture and band fastening ends are snapped together and fastened. The fastening mechanism may also be in other forms according to various applications, such as a buckle, snap hook, S hook, popper, press stud, hook, Velcro cinch strap, fastener, carabiner, and/or other fastening mechanisms that can be configured to fasten two free ends to each other or a rack dolly or other carrier.
The adjusting mechanism 101 may comprise a securing mechanism 103 to secure the cincture 1102 relative to the band 1202 once the desired length of the adjustable strap assembly 100 has been set. In one embodiment, the securing mechanism 103 may comprise one or more securing elements (e.g., 1112 shown in FIGS. 2, and 1212 shown in FIG. 4) attached to the cincture 1102 and the band 1202. Preferably a portion of the securing elements is attached to the cincture 1102 and another portion of the securing element is attached to the band 1202. In one example, the securing elements may comprise a male (e.g., 1112 shown in FIG. 2) and a female part (1212 shown in FIG. 4). The male part may include a projecting portion (e.g., 1112a shown in FIG. 3) and may be part of a snap, a press stud, a popper, an interlocking disc, a snap hook, an S hook, a button or Velcro hooks. The female part may be configured to receive the projecting portion and may be an interlocking disc, a hook hole, a button hole or Velcro loops. In another example, the securing elements may comprise two male parts. For example, the two male parts may each be a hook. In this regard, a hook on the cincture 1102 is coupled to a hook on the band 1202. In the embodiment illustrated in FIG. 1, the securing mechanism 103 comprises a plurality of securing elements. The securing elements include a male part in the form of a stud 1112 (shown in FIGS. 2 and 3) and a female part, such as a reinforced through hole 1212 (shown in FIG. 4) in the band 1202 into which the stud 1112 can be inserted. Depending on the application there may not be the same number of securing elements attached to the cincture 1102 as are attached to the band 1202. For example, there may be two or more reinforced through holes 1212 and only one stud 1112. The parts of the securing elements may be attached to or formed on the cincture 1102 and the band 1202 by glue, adhesive, staple, hammering, plying, sewing, drilling, reaming, milling, and/or any other suitable method or combination of methods.
In another embodiment, the adjusting mechanism may comprise a cam buckle, side release buckle, ladderloc adjustment buckle, snap hook, tri-glide, D-ring assembly, and/or any other suitable mechanisms that allows adjustment of the overall length of the adjustable strap assembly and can secure the cincture 1102 relative to the band 1202 to maintain the overall length of the adjustable strap assembly even when stressed and securing a bundle.
FIG. 6 illustrates a front view of the cincture 1102 of an adjustable strap assembly 600 including a cam buckle 602 attached to the cincture 1102. D-rings 1109 and 1209 are attached to the adjusting ends of the cincture 1102 and band 1202, respectively to eliminate any loose hanging ends when the adjustable strap assembly 600 is adjusted to the desired length. The adjustable strap assembly 600 comprises a fastening mechanism that comprises a cincture hook 1110 and a band hook 1210. The cincture hook 1110 and the band hook 1210 are configured to be attached to their associated end (e.g., the cincture fastening end 1106 and the band fastening end 1206). FIG. 7 depicts the cincture 1102 assembled with the band 1202 employing the cam buckle 602 as part of the adjusting mechanism to form the adjustable strap assembly.
FIG. 8 illustrates an exemplary cam buckle. With references to FIGS. 6-8, the cam buckle 800 may include a base member 802 and a lever member 804. The lever member 804 may include teeth, tab, thumb button, and/or any other types of projections that contact the cincture 1102 or band 1202 that holds the relative positions of the cincture 1102 and the band 1202 once the user has adjusted the adjustable strap assembly to a desired length. The cam buckle may be a toothless cam buckle and may include one or more bars to secure the band 1202. The base member may include two or more base elements and one opening between the two adjacent base elements. For example, the base member 802 may include a first base element 802a and a second base element 802b. An opening 806 shaped for insertion of the band 1202 may be formed between the first and second base elements (802a, 802b). The band 1202 may be inserted through the opening 806 and may be wrapped around one of the first base element and the second base element depending on the way of attaching the cam buckle onto the cincture 1102. At least a portion of one of the cincture 1102 and the band 1202 may be made from a sturdy elastic material to ensure constant tension when the adjustable strap assembly is securing a bundle.
The exemplary adjustable strap assembly 100 may be used in different manners. One of the methods to use the strap assembly 100 is illustrated in FIGS. 9 and 10. With reference to FIGS. 1, 9 and 10, after the cincture 1102 is assembled with the band 1202, namely, the cincture 1102 extends through the second sleeve 1208 and the band 1202 extends through the first sleeve 1108, the length of the adjustable strap assembly 100 can be adjusted by pulling at least one of the cincture fastening end 1106 and the band fastening end 1206. In this embodiment, the length of the adjustable strap assembly 100 is adjusted by pulling one of the first fastening element 1110 and the second fastening element 1210, or pulling both of the first and second fastening elements (1110, 1210) in opposite directions.
When the cincture fastening end 1106 and the band fastening end 1206 is fastened by a fastening mechanism (e.g., the first fastening element 1110 and the second fastening element 1210 shown in FIG. 1), a first loop (e.g., a first loop 902 shown in FIG. 9) may be formed to allow an insertion of a first object 906. The first object can be a coil or an extension cord. To secure the cincture 1102 relative to the band 1202, one or more first securing elements may engage with one or more second securing elements. For example, as shown in FIG. 9, the first securing element 904 may engage with one of the second securing elements (not shown). In another embodiment, the adjustable strap assembly 100 may also be used to store an extension cord and free ends, i.e., the plugs, of the cord in separate spaces. As shown in FIG. 10, plugs of the extension cord may be placed in first loop 1004 and second loop 1006 separately.
In another embodiment, the fastening ends (e.g., the cincture fastening end 1106 and the band fastening end 1206 shown in FIG. 1) of the adjustable strap assembly 100 may not be fastened to each other. For example, the adjustable strap assembly 100 may be used to secure, a backpack 1102 (shown in FIG. 11) or a suitcase, a brief case, and/or a parcel, to a luggage rack 1104 to prevent it from falling down. In this regard, the adjustable strap assembly 100 may wrap around the backpack 1102. Each of the fastening elements (1110, 1210) is then hooked with one of the two handles (e.g., 102a, 102b as shown in FIG. 12) to secure the backpack.
The cincture 1102 and the band 1202 may be used in different manners with variance in assembling the cincture and band, securing mechanism, adjustment mechanism and fastening mechanism. For example, in an instance in which a cam buckle is used as the securing mechanism, the length of the strap assembly 100 may be adjusted by pulling one of the cincture and band fastening ends.
FIG. 11 illustrates dimensions of an adjustable strap assembly in accordance with an exemplary embodiment of the present invention. The length of the cincture 1102 may range from being substantially the same length as that of the band 1202 to many times as long as the band or vice versa. For example, the length of the cincture 1102 (L1) may be the same as that of the band 1202 (L2). In one example, L1 and L2 may be about 13.75 inches. As discussed above, the cincture 1102 may have one or more first securing elements (e.g., 1112a, 1112b, 1112c). The one or more first securing elements 1112 may be aligned with each other. The band 1202 may have one or more second securing elements (e.g., 1212a, 1212b, 1212c). The number and spacing of first and second securing elements will depend on the application and whether the length of the adjustable strap assembly is a gross or fine adjustment. Similar to the first securing elements, the one or more second securing elements may be aligned with each other. Also the spacing of the securing elements attached to cincture 1102 may have different spacing than the securing elements attached to the band 1202 and may not be equally spaced. In one embodiment, one of the second securing elements may be engaged with one of the first securing elements to secure the cincture 1102 relative to the band 1202. The placement and the number of the first securing elements on the cincture 1102 may be similar to those of the second securing elements on the band 1202. For example, the shortest distance (e.g., L3) between the first securing element (e.g., the first securing element 1112a) and the cincture adjusting end 1104 may have the same length as the shortest distance (e.g., L4) between the second securing element (e.g., the second securing element 1212a) and the band adjusting end 1204. In one example, the length of L3 and L4 may be about 1.25 inches. Distance between adjacent first securing elements may be the same. For example, distance (e.g., L5) between the first securing elements 1112a and 1112b may have the same length as distance (e.g., L6) between the first securing elements 1112b and 1112c. In one example, L5 and L6 may be about 1 inch. Similarly, distance between adjacent second securing elements such as distance L7 between the second securing element 1212a and 1212b, and distance L8 between the second securing element 1212b and 1212c may have the same length. In one example, L7 and L8 may be about 1 inch. The shortest distance between the second securing element 1212c and the band fastening end 1206 may have length of L10. In one example, the length may be about 2.5 inch.
It should be understood that the placement of the first and second securing elements, distance between adjacent first and adjacent second securing elements, distance between the second securing elements and the band fastening end 1206 may not be limited to the examples described above. The first and second securing elements may be placed in different patterns. Length of distance between adjacent securing elements may vary according to various applications and usages.
