DETAILED DESCRIPTION

[0046] In the drawings, thicknesses of lines and sizes of constituent elements may be exaggerated for clarity and convenience in explanation.

[0047] Further, terms to be described later are defined in consideration of the functions of the present invention, and may differ depending on the intentions of a user or an operator or custom. Accordingly, such terms should be defined on the basis of the contents of the overall specification. As described above, belts or straps are attached to a hiking backpack or a bag. In the case of hiking backpack, straps can be applied for various purposes such as shoulder straps, chest straps, and waist straps. So, the straps can be applied in the concept that includes all kinds of straps and cords for connection and detachment, and hereinafter, it will be described uniformly as a strap.

[0048] The embodiments described below can be realized in various different forms. In order to more clearly describe the characteristics of the embodiments, a detailed description of matters well known to those of ordinary skill in the art to which the present embodiments belong will be omitted.

[0049] FIGS. 2 to 6 illustrate a first embodiment in which a strap bar according to the present invention is applied to a strap adjuster as a strap accessory. FIG. 2, (a) is a perspective view illustrating a disassembled state and FIG. 2, (b) is a perspective view illustrating an assembled state of the strap adjuster according to an embodiment of the present invention, FIG. 3, (a) is a perspective view of the disassembled state and FIG. 3, (b) is a front view of the assembled state of the strap adjuster viewed from a different direction, FIG. 4, (a) is a sectional view taken along line A-A of FIG. 3, (b), and FIG. 4, (b) is a sectional view of the disassembled state taken along line A-A of FIG. 3, (b), FIG. 5, (a) is a plan view and FIG. 5, (b) is a side view illustrating an example of a strap bar, and FIG. 6 is a sectional view taken along line B-B of FIG. 3, (b), showing a connected state of a strap.

[0050] The strap bar device according to the present invention includes: a strap accessory which includes two support parts facing each other to be spaced apart from each other, and a through-hole and a support groove formed in the two support parts to face each other; and a strap bar which is inserted through the through-hole and is supported in the through-hole and the support groove, wherein a strap is connected to the strap bar by wrapping around the strap bar.

[0051] Referring to FIGS. 2 to 6, the strap bar device according to the present invention includes a strap adjuster 100 as the strap accessory, and the strap bar 20 which is detachably assembled to the strap adjuster 100.

[0052] The strap adjuster 100 generally has a strap S connected to both sides thereof, wherein one side is fixed by sewing, and the other side is adjustable in length without being fixed. That is, the strap connected to both sides are divided into a fixed end and a free end.

[0053] At least one of the strap bar connected to the strap of the free end and the strap bar connected to the strap of the fixed end may be formed as a detachable type.

[0054] Since the strap of the free end is not fixed by sewing for length adjustment, it is easily detachable from the strap adjuster. Therefore, the strap bar connected to the strap of the free end is not inconvenient in assembling work even if it is not detachably mounted. However, since the strap of the fixed end is mounted by wrapping around the fixed end and being sewed, if a user wants to replace the strap after being mounted, the entire strap must be removed. Therefore, it is more preferable to make the strap bar of the fixed end as a detachable type.

[0055] The strap adjuster 100 has opposing support parts 110 and 120 formed on both sides thereof through which the strap passes, and the strap bar 20 according to the present invention and a cross bar 130 are mounted between the support parts 110 and 120 to connect the strap.

[0056] The strap bar 20 is formed in a pin shape and is mounted on both support parts 110 and 120 of the strap adjuster 100.

[0057] For this purpose, a through-hole 111 through which the strap bar 20 passes is formed in one of the support parts 110, and a support groove 121 is formed in the other support part 120 to face the through-hole 111, so that the front end of the strap bar 20 is inserted and supported.

[0058] Therefore, assembly is completed by inserting the strap bar 20 into the through-hole 111 and placing the front end in the support groove 121.

[0059] That is, the front end of the strap bar 20 is supported in the support groove 121, and the rear end of the strap bar 20 is coupled to be supported in the through-hole 111.

[0060] Here, the cross-sectional shapes of the through-hole 111 and the support groove 121 are made in a polygonal shape, and coupling portions of the strap bar 20 corresponding thereto are also formed in the polygonal shape to match the through-hole 111 and the support groove 121, so that the strap bar 20 can be stably fixed without rotation in the coupled state.

[0061] A head groove 112 expanded more than the through-hole 111 can be formed on the outside of the through-hole 111, and a head part 21 seated in the head groove 112 can be expanded and formed at the rear end of the strap bar 20.

[0062] Moreover, a coupling protrusion 22 is protrudingly formed at the front end of the strap bar 20, so as to be inserted into and coupled to the support groove 121. It is preferable that the coupling protrusion 22 is formed to be stepped from a body of the strap bar 20 and to be smaller than the body of the strap bar 20.

[0063] The sizes and shapes of the head groove 112, the head part 21, the support groove 121, the coupling protrusion 22, and the like can be formed in various ways, and can be arbitrarily applied depending on the strap accessories applied.

[0064] For example, as illustrated in FIG. 3, (b) and FIG. 4, a protrusion 122 may be further formed outward from the support part 120 to sufficiently secure a space of the support groove 121 when the support groove 121 is formed. Accordingly, the head part 21 of the strap bar 20 may protrude outward from the opposing support part 110 such that the protruding shape of the head part 21 is the same as the protrusion 122. Therefore, the protruding shapes of both support parts 110 and 120 can be symmetrically formed, thereby providing the aesthetic appearance.

[0065] The strap bar 20 may be provided with fixing means for maintaining a coupled state between the strap accessory and the strap bar 20.

[0066] Therefore, the strap bar 20 can be fixed to the strap accessory by the fixing means or separated from the strap accessory by releasing the fixing means.

[0067] The fixing means includes: a recess 23 formed on one side near the outer end, i.e., the head part 21 of the strap bar 20; a hook piece 24 elastically extended in the longitudinal direction inside the strap bar 20 within the recess 23; a locking part 25 protruding above the one side from the free end of the hook piece 24; and a coupling groove 27 formed between the head part 21 and the locking part 25.

[0068] Therefore, when the strap bar 20 is completely coupled to the strap adjuster 100, the support part 110 is coupled to the coupling groove 27 as the hook piece 24 is elastically retained to the inside of the through-hole 111 such that the strap bar 20 is coupled and fixed.

[0069] As illustrated in the plan view of FIG. 5, (a), the cross-section of the strap bar 20 may be formed longer on one side like a rectangle. Specifically, the direction of the longer side coincides with the lateral direction of the hook piece 24.

[0070] This is to form the recess 23 to form the hook piece 24 as a fixing means, thereby compensating for the point that the thickness of the corresponding part may become thin and the strength may be weakened. So, it is preferable that the fixing means is formed long in the direction in which the strap is pulled.

[0071] FIG. 6 illustrates a state in which the strap S is connected in both directions of the strap adjuster 100, wherein one side of the strap forms the fixed end by wrapping around the strap bar 20 and being fixed with a sewing line Ss, and the other side of the strap wraps around the cross bar 130 so that two lines are extended as they are to allow adjustment of the length of the strap.

[0072] Therefore, in a case in which the strap bar 20 is damaged during the use of the strap adjuster, only the strap bar 20 can be separated and easily replaced with a new strap bar. In addition, if other parts, such as the cross bar 130, are damaged, since the strap adjuster 100 must be separated from the strap of the fixed end, so the strap bar 20 can be easily detached, thereby facilitating the exchange of the strap adjuster 100.

[0073] FIGS. 7 to 12 illustrate a second embodiment of the strap bar according to the present invention applied to a buckle which is widely used in a backpack, wherein FIG. 7 is a perspective view of the buckle as a strap accessory, FIG. 8 is an exploded perspective view of FIG. 7, and FIG. 9 is a perspective view illustrating an assembled state of FIG. 7.

[0074] Referring to FIGS. 7 to 9, the buckle 200 as a strap accessory includes a plug member 200a and a socket member 200b, which are detachably connected to each other, and the strap is connected backwards, wherein one side of the strap is sewed and connected in a fixed state. In the drawings, it is illustrated that the strap connected to the plug member 200a is in a fixed state.

[0075] Facing support parts 210 and 220 are formed at the rear ends of the plug member 200a and the socket member 200b, and the strap bar 20 according to the present invention is mounted between the support parts 210 and 220 to connect the strap.

[0076] A through-hole 211 through which the strap bar 20 passes is formed in one of the support parts 210, and a support grove 221 is formed in the other support part 220 to face the through-hole 211, so that the front end of the strap bar 20 is inserted and supported.

[0077] Therefore, assembly is completed when the strap bar 20 is inserted through the through-hole 211 and the front end is seated in the support groove 221.

[0078] A hook piece 24 as a fixing means is mounted at the rear end of the strap bar 20, and is elastically coupled with the through-hole 211.

[0079] The configuration of the strap bar 20, the through-hole 211 and the support groove 221 in which the strap bar 20 is inserted may be made in the same manner as the configuration of the first embodiment, so a repetitive description will be omitted.

[0080] FIG. 10 to 12 are sectional views and front views illustrating a state in which the strap bar is removed from a buckle, wherein FIG. 10, (a), FIG. 11, (a) and FIG. 12, (a) are sectional views taken along lines C-C, D-D, and E-E of FIG. 10, (b), FIG. 11, (b) and FIG. 12, (b), respectively.

[0081] Referring to FIGS. 10 to 12, a strap removal state will be described. In the state in which the strap bar 20 is coupled to the buckle 200, as illustrated in FIG. 10, (a), when a user presses the locking part 25 of the hook piece 24 in an arrow direction, the strap bar is removed out. FIG. 11 illustrates a state in which the hook piece 24 moves inside the through-hole 211, and FIG. 12 illustrates a state in which the hook piece 24 gets completely out of the through-hole 211.

[0082] That is, the strap bar 20 can be simply separated just by pressing and pushing the hook piece 24.

[0083] For an efficient space utilization when the locking part 25 of the front end of the hook piece 24 is pressed, as illustrated in FIG. 5, an inclined surface 26 may be formed on the inner side of the front end of the hook piece 24. By forming the inclined surface 26, a deeper rotation angle of the hook piece 24 can be secured.
