Description BAND COMBINATION FORMATION OF SANDAL SHOES Technical Field
[1] The present invention relates to sandals having straps warping the top of the foot, and more particularly, to a fastener structure for sandal straps, which is capable of being modified to various types and being fixed to the sandal, according to sandal user's preference. Background Art
[2] In general, footwear such as sandals, etc., has straps wrapping the top of the foot and fixing the foot thereto. The strap is fixed to the sandal such that one end or both ends of the strap are placed between an outsole and a shoe liner of the sandal and then fixedly joined together by bonding or by sewing.
[3] The body of such a sandal should be carefully designed because its aspect is determined according to design. Especially, design of the upper portion of the sandal for the top of the foot determines the entire outward aspect of the sandal, because the upper portion of the sandal is mainly shown. However, once the strap for the prior art sandal is fixed to the body of the sandal, it cannot be modified to change the outward aspect of the sandal according to a wearer, as long as he/she does not buy another type of sandal.
[4] On the other hand, sandal durability is dependent on fixing force between the strap and the body of the sandal. The prior art structure for fixing a strap to a sandal has disadvantages in that a strap for a sandal is easily cut or separated from the sandal, and once the strap is cut or separated from the sandal, it is difficult to fix the strap to the sandal, again, such that the sandal can be thrown away.

Best Mode for Carrying Out the Invention [20] Referring to Fig. 1 to Fig. 8, the preferred embodiments of the present invention are described in detail below. [21] The fastener for a strap for a sandal according to the present invention is implemented in two types, which are described in detail below. [22] First embodiment
[23] As shown in Figs. 1 and 2, the fastener structure for straps for a sandal according to the first embodiment of the present invention includes a plurality of clasps 20 which are fixed to body 10 of the sandal along edge of the sandal at an even or irregular interval, and a plurality of hooks 40 connected to both ends of straps 30, such that the hooks 40 are coupled to the clasps 20, respectively. [24] Especially, the clasp 20 includes a binding unit 21 is buriedly installed between a shoe liner 11 and an outsole 12 of the body 10 and fixed therebetween by binding force, and a clipping unit 22 having elasticity bent at one end of the binding unit 21 to shape a character S, approximately. [25] Also, the hook 40 coupled to the end of the strap 30 is composed of a binding hole 41 to be passed through the end of the strap 30, such that the end of the strap 30 passed through the binding hole 41 can be reunited with part of the strap 30 before passing through the binding hole 41 and fixed to each other, and a hooking hole 42 for hooking to the clipping unit 22 of the clasp 20. [26] Now, operation of such a first embodiment of the present invention is described in detain below. [27] First of all, the hooking hole 42 of the hook 40 fixedly installed to one end of the
strap 30 is hooked by one of the clipping units 22 of the clasps 20 which are fixed to along the edge of the body 10 of the sandal. After that another hooking hole of the hook fixedly installed to opposite end of the strap 30 is also hooked by one of the clipping units, which are aligned at the opposite of the currently used clasps 20.
[28] The remaining hooks 40 are correspondingly coupled to the clasps 20 based on the description as mentioned above. Here, the coupling fashion between the hooks 40 and the clasp 20 is variously performed according to wearer's preference. For example, as shown in Fig. 5, there are a method for crossly coupling straps, and a method for serially aligning straps, etc. On the other hand, as show in Fig. 6, the straps 30 can be implemented like that they are collected at a collecting unit 31, in which the collecting unit 31 inserting predetermined patterns in the center portion thereof, and then strap portions 32 of the straps are hung from the collection unit 31 in the radial direction. Also, the collecting unit 31 can be implemented to include a hook on the upper side thereof, such that variously shaped accessories, such as characters, etc., can be separatedly attached thereon. In addition, the collecting unit 31 can be implemented to include buckles attached therearoud, such that strap portions 32 can coupled to the buckles, and thus hung in the radial direction with respect to the collecting unit 31. Such a description can be identically applied to the second embodiment of the present invention.
[29] On the other hand, when the strap(s) 30 are cut or in order that the positions of the strap(s) are changed, the straps 30 can be separated from the clasps 20 by the sequence reverse to that of installation sequence as mentioned above. Such procedure is also identically applied to the second embodiment of the present invention.
[30] Second embodiment
[31] As shown in Fig. 3 and Fig. 4, the fastener structure for a strap for a sandal according to the second embodiment of the present invention includes a plurality of clasps 200 which are fixed to body 10 of the sandal along edge of the sandal at an even or irregular interval, and a plurality of hooking buttons 400 connected to both ends of straps 30, such that the hooks 40 are coupled to the clasps 200, respectively.
[32] Especially, unlike the first embodiment of the present invention, the clasp 200 includes a binding unit 201 performing coupling in a state where it is buriedly installed between a shoe liner 11 and an outsole 12 of the body 10, and a ring unit 204 shaped as an approximate ring and integrately formed with the binding unit 201, in which the ring unit 204 has an opening 203 which is opened or closed by an elastic lever 202 which is elastically operated and has the same as curvature of the ring unit 204.
[33] Here, the elastic lever 202 is supported by a spring (not shown) installed in the inside the ring unit 204. When the elastic lever (202) is pulled along the periphery of the ring unit 204, the elastic lever 202 is slid into the ring unit 204 to open the opening
203, and when releasing the state where the elastic lever 202 is pulled, the elastic lever 202 is returned to the initial location by elasticity of the spring to close the opening 203.
[34] On the other hand, the hooking button 400 coupled to end of the strap 30 includes a coupling unit 401 penetratedly coupled to the end of the strap 30, an ending unit 402 apart from the coupling unit 401 at a predetermined distance, and a hooking ring unit 403 located within the radius d of the ring unit 204 and between the coupling unit 401 and the ending unit 402.
[35] Now, operation of such a second embodiment of the present invention is described in detain below.
[36] Firstly, in a state where the elastic lever 202 of the ring unit 204 is pulled to open the opening 203, the hooking ring unit 403 attached to one end of the strap 30 is inserted into the ring unit 204 through the opening 203. After that, the elastic lever 202 pulled to open the opening 203 is released such that the elastic lever 202 can close the opening 203.
[37] Since the holing ring unit 403 is located within the ring unit 204. Also, external radius of the ending 402 is larger than the inner radius of the ring unit 204, the hooking button 400 is not arbitrarily escaped from the ring unit 204, such that the hooking button 400 can perform firm fixing operation.
[38] On the other hand, when the strap(s) 30 are cut or in order that the positions of the strap(s) are changed, the straps 30 can be separated from the clasps 20 by the sequence reverse to that of installation sequence as mentioned above. Such procedure is also identically applied to the second embodiment of the present invention.
[39] Third embodiment
[40] As shown in Fig. 7 and Fig. 8, the fastener structure for a strap for a sandal according to the third embodiment of the present invention includes a plurality of clasps 300 which are fixed to body 10 of the sandal along edge of the sandal at an even or irregular interval, in which one end of the clasp 300 is hurriedly fixed between a shoe liner 11 and an outsole 12 of the body 10 and the other end of the clasp 300 bent to be shaped as U, in which a hooking pin 310 is installed.
[41] On the other hand, each end of upper straps 400 wrapping the top of the foot has a hook 410 bent to be shaped asU and located with the bent portion such that the hook 410 hooks the hooking pin 310.
[42] More specifically, the hook 410 has plates 411 at both ends thereof, in which the plates 411 are identical to one another, and form sloped slots 41 la to hook the hooking pin 310. The plates 411 are connected to one another by pins 412 which are fixed within the bent portion of the upper straps 400.
[43] Therefore, when the upper strap 400 is fixed to the clasp 300, the hook 410 attached
to the end of the upper strap 400 is hooked to the hooking pin 310 of the clasp 300. Namely, the hooking pin 310 is accommodated to the sloped slots 411a formed at both plates 411, respectively, thereby coupling the upper strap 400 to the clasp 300. Such a procedure is performed until all the straps are coupled to the clasps, respectively. Industrial Applicability
[44] As mentioned above, the fastener structure for a strap for a sandal according to the present invention has advantages in that, since the straps are separated from the sandal body, in which a plurality of clasps are fixedly aligned along the relatively outer side of the sandal body, a wearer can change the positions of the straps according to wear's preference, and also, when a strap is damaged or cut, since only such a cut or damaged strap can be replaced with new one, it is cost effective,
