Description

  The present invention relates to a footwear belt fastener, and more particularly, to a footwear belt fastener used to attach a belt hung around an upper or a heel to an intermediate portion of a footwear body.

  The footwear such as sandals exposes the heel portion when worn, and thus can be easily attached / detached, but cannot maintain a stable wearing state and is unsuitable for driving and running a car. Therefore, recent footwear is often provided with a belt such as a so-called back strap in order to fix the heel to the footwear and maintain a stable wearing state.

  Generally, the belt is pivotally or completely fixed to the footwear or is integral with the footwear and cannot be easily removed. In other words, the belt fastener has a structure that cannot be easily detached, and it is not planned to remove or replace the belt according to time and circumstances.

  Furthermore, recent fasteners are often used not only for fastening the original belt but also for providing a decorative effect. However, since the conventional footwear belt fastener is not scheduled to be removed and replaced as described above, it is difficult to change the design from the fastener at the time of purchase.

Accordingly, an object of the present invention is to provide a footwear belt fastener for footwear that makes it easy to attach and detach and replace a footwear belt, and that can firmly fix the belt, and that can be easily replaced.

  The device according to claim 1 for solving the above-mentioned problems comprises a receiving member and an insertion member that can be engaged and separated from each other, and a fixing pin that is fitted into a hollow shaft of the insertion member, After the insertion member is inserted into the receiving member, the hollow shaft is firmly brought into close contact with the receiving member by the action of the fixing pin by inserting the fixing pin into the hollow shaft. The belt is fastened to the footwear by which the insertion member and the receiving member can be separated by pulling out the fixing pin and releasing the action. It is a tool.

  In a preferred embodiment, the insertion member includes a base and the hollow shaft erected at the center of the base, and an end portion of the hollow shaft is expandable / contractable by being slitted. It is said. In addition, the receiving member includes a base and a support cylinder that is erected at the center of the base, and a reduced diameter portion that locks the hollow shaft inserted into the upper end of the inner surface of the support cylinder. It is formed. The upper end portion of the inner peripheral surface of the reduced diameter portion of the support cylinder is preferably a tapered surface.

  The expanding / contracting portion has an outwardly expanding shape, and a protrusion that is pressed by the fixing pin when the fixing pin is fitted into the hollow shaft on the inner side surface of each tip of the expanding / contracting portion. A part may be formed.

  Further, a recessed portion for accommodating the head of the fixing pin is formed in the base of the insertion member, and when the fixing pin is fitted into the insertion member, the inner peripheral surface of the recessed portion and the fixing pin A hooking groove is secured between the head and the outer peripheral surface of the head, and more preferably, a decorative element is provided on the base of the insertion member and / or the head of the fixing pin that protrudes to the front side during use.

  According to the present invention, it is possible for any person to easily attach and detach the fastener, and the belt can be detached and replaced according to time and circumstances, and the fastener itself can be easily replaced. The belt and the fastener can be selectively exchanged according to the user's preference, and there is an effect that the purchaser's preference can be satisfied sufficiently from the viewpoint of fashion.

  The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of an embodiment of a footwear belt fastener according to the present invention, which includes a receiving member 1, an insertion member 11 inserted into the receiving member 1, and a receiving member 11. It consists of a fixing pin 21 that plays a role of strengthening the fixed state with respect to the member 1.

  The receiving member 1 is formed by standing a support cylinder 2 at the center of a base 3. A reduced diameter portion 5 for locking the hollow shaft 13 of the insertion member 11 is formed on the inner surface of the support cylinder 2 as will be described later. The upper end portion of the inner peripheral surface of the reduced diameter portion 5 is preferably a tapered surface 6 in order to facilitate the insertion of the hollow shaft 13.

  In the illustrated example, the opening 4 is provided in the support cylinder 2, but the opening 4 is not essential. Usually, since the receiving member 1 is located on the inner side of the footwear and comes into contact with the foot, it is preferable to suppress the thickness of the base 3 as much as possible in order to minimize the uncomfortable feeling given to the foot when worn.

  The insertion member 11 is formed by providing a hollow shaft 12 at the center of a base 13, and a plurality of slits 14 extending in the length direction are inserted at the distal end of the hollow shaft 12, and a plurality of front cracks 15 are formed. It is formed. The lower end of the cracked portion 15 protrudes outward, and preferably a protrusion 16 is formed on the inner surface thereof. Since each tip crack portion 15 projects outward, the end portion of the hollow shaft 12 exhibits a shape that expands outward. Further, since the slits 14 are provided, each tip 15 can be slightly tilted inward and outward by being pressed, so that the end portion of the hollow shaft 12 can be slightly expanded and contracted. Become.

  Further, the base 13 of the insertion member 11 is formed with a recessed portion 17 in which the head 22 of the fixing pin 21 is accommodated, and an insertion port 18 for inserting the pin shaft 23 of the fixing pin 21 is formed at the center of the recessed portion 17. It is formed. Then, when the pin shaft 23 of the fixing pin 21 is inserted into the pin insertion port 18 and the head 22 is stored in the recessed portion 17, the space between the inner peripheral surface 19 of the recessed portion 17 and the outer peripheral surface of the head 22. A retaining groove 20 for securing the head 22 with a fingertip, a screwdriver or the like is secured (see FIGS. 3 and 4).

  In order to fix the belt 31 to the footwear main body using the fastener having the above-described configuration, first, the inner side of the upper 32 is inserted into an insertion hole formed so as to communicate with the upper 32 of the footwear main body and the belt 31. The support cylinder 2 of the receiving member 1 is inserted.

  Next, the hollow shaft 12 of the insertion member 11 is pushed into the reduced diameter portion 5 of the support cylinder 2 exposed in the insertion hole of the belt 31. At that time, each tip crack portion 15 at the tip of the hollow shaft 12 hits the tapered surface 6 and is slid inwardly. That is, the expansion / contraction part composed of the plurality of cracks 15 is narrowed by being pushed from above, and can pass through the reduced diameter part 5.

  The expanded / contracted portion passes through the reduced diameter portion 5 in a constricted state, and then returns to the original expanded state due to its elasticity, and is accommodated in the wide diameter portion 7 below the reduced diameter portion 5. In this state, since the expansion / contraction portion is locked by the reduced diameter portion 5, the insertion member 11 is held to some extent by the support cylinder 2, but when the insertion member 11 is pulled strongly, the expansion / contraction portion becomes the reduced diameter portion. Since it is constricted by 5, it can be easily extracted.

  In order to prevent the insertion member 11 from coming off, the fixing pin 21 is inserted into the insertion member 11 inserted into the receiving member 1. That is, when the pin shaft 23 is inserted from the pin insertion port 18, the peripheral surface of the pin shaft 23 presses the protrusion 16 on the inner surface of each cracked portion 15 to make the expansion / contraction portion expanded, and this state is maintained. Thus, since the expansion / contraction part cannot be in a contracted state unless the fixing pin 21 is removed, the expansion / contraction part cannot pass through the reduced diameter part 5. That is, the insertion member 11 cannot be extracted from the receiving member 1.

  When the insertion member 11 is pulled out from the receiving member 1 when the fastener is replaced, first, the fixing pin 21 is pulled out. In that case, by hooking a fingertip, a screwdriver, or the like on the latching groove 20, The pulling-out operation becomes easy.

  Usually, the head 22 of the fixing pin 21 that is exposed to the outside is appropriately provided with a pattern or coloring, and in some cases, a decorative element other than a circular shape such as a heart shape or a star shape is added. In addition, by unifying the diameter and length of the pin shaft 23, the fixing pin 21 can be arbitrarily replaced to enjoy its decorative effect.

  Although the invention has been described in some detail with respect to its most preferred embodiment, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention. It is not restricted to the specific embodiment other than limiting in.
