Description

  The present invention relates to a belt size adjuster. The present invention has been developed with respect to a size adjuster for women's shoes of a type in which the heel portion is fixed with a band such as a sandal, but can also be applied to a general belt such as a waist belt. In the following description, a size adjusting tool for women's shoes will be described as an example.

Women's shoes of the type in which the heel part is fixed with a band often have an adjustable band length, and a device similar to a waist belt buckle is used for that purpose. For example, it is like the following patent document 1. In this prior art, a buckle and a male / female snap button are integrated, the length of the belt is adjusted by the former, and the both ends of the separated belt are hooked by the latter.
Japanese Utility Model Publication No. 6-55407

  In the size adjuster of Patent Document 1, since both ends of the belt are detached by attaching and detaching snap buttons, when the belt is removed, the belt hangs loosely and looks bad. In addition, the wearer extends his hand from above while tilting his body and engages the snap button. However, the wearer may not be able to fasten or lose his posture. In addition, the snap button was driven into the belt by a hitting machine, so the back of the button (often made of metal) hit the wearer's skin directly.

  Accordingly, the present invention provides a women's shoe size characterized in that the belt can be detached even without being separated, the engagement of male and female buttons is unnecessary, and the skin of the wearer is hardly touched. The purpose is to provide an adjustment tool. It is a further object of the present invention to provide an adjuster having a relatively long belt size adjustment distance, away from such special applications.

  The present invention relates to a belt size adjuster that can adjust the length of an overlapping portion of a belt divided into an upper belt and a lower belt, the guide rail fixed to either the upper or lower belt, A slider that can be slidable and fixed at a specific position, and a buckle having a stop pin that can be selectively engaged with a plurality of adjustment holes provided on the belt opposite to the belt, the slider and the buckle Are integrated.

  In the present invention, the belt length can be adjusted by selectively fixing the position of the guide rail and the slider. Further, the belt length can be adjusted by selectively engaging the buckle adjustment hole and the upper belt. Therefore, since the belt length can be adjusted twice, the adjustment distance is longer than in the case where each belt is used alone.

  In the present invention, since the male and female snap buttons are not used, the belt must be removed from the buckle to divide the belt, and this is not possible unless consciously done. For this reason, it is not unsightly when the button is removed, and the operation of engaging the button becomes unnecessary.

  Furthermore, when the present invention is applied to women's shoes, the lower belt is always positioned below the slider and the buckle. Therefore, since the slider and the buckle do not directly hit the foot of the shoe wearer, the foot does not hurt.

The following can be used as the guide rail.
(1) A plurality of protrusions extending in a direction perpendicular to the longitudinal direction of the rail are arranged in parallel (for example, Japanese Utility Model Publication No. 6-13111, Japanese Patent No. 3486344, Japanese Patent No. 3430307, Japanese Patent No. 3340260, Japanese Patent Laid-Open No. 2001-131816, JP 2001-146619)
(2) One or two rows of shallow square columnar locking teeth arranged intermittently in the longitudinal direction of the rail (for example, see Japanese Patent No. 2860446)
(3) One or two rows of shallow triangular columnar locking teeth arranged intermittently in the longitudinal direction of the rail (see Example 1 below)

  In either case, since the protrusions and the locking teeth are intermittently arranged, after the size adjustment is completed, the protrusions and the locking teeth at the closest position become stoppers and are fixed at the positions. Since the triangular columnar locking teeth of (3) have an inclined side, a special effect is obtained in that the belt can be tightened only by pulling the upper belt in the shrinking direction by a mechanism described later.

  Since the rail is usually a long and narrow plate, it is preferable that both sides in the longitudinal direction be thick portions in order to increase the strength.

  As the slider, those shown in the patent / utility model publication cited in the previous paragraph can be used.

As a method for integrating the slider and the buckle, there are the following methods.
(1) A nail is raised from the slider side, and the nail is engaged with the outer frame of the buckle or the central cross bar (see Example 1 described later).
(2) A nail is raised from the buckle side and engaged with the outer frame of the slider with the nail.
(3) Use an independent connector that connects the buckle and the slider.

  Various buckle designs are already on the market, and the buckle and slider can be fixed only by pressing with a nail, for example, as described above. It is extremely easy to change the design to that of the previous design.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a women's shoe 1 using the size adjuster of the present invention. An adjusting tool 3 for adjusting the length of the shoe belt 2 fixed to the user's heel is provided. 2 is a cross-sectional view taken along the line 2-2 in FIG. 1, FIG. 3A is an enlarged plan view (natural state) of the adjustment tool 3, FIG. 2B is a longitudinal sectional view, and FIG. (B) is the longitudinal cross-sectional view.

  As shown in FIG.1 and FIG.2, this shoe belt 2 is divided into three layers at a parting point. The lower belt 21 and the upper belt 22 are overlapping portions of the separated shoe belt 2. The intermediate layer is the guide rail 4, and both ends 41 and 42 are fixed to the lower layer 21. On the guide rail 4, a slider 5 capable of sliding and fixing the position is attached. A buckle 6 having a stop pin 63 is fixed to the slider 5. The stop pin 63 can be selectively engaged with a plurality of adjustment holes 23 (FIG. 1) provided in the upper belt 22.

  Looking at each component in more detail, as shown in FIGS. 3 and 4, the guide rail 4 is an elongated substrate 43 made of synthetic resin, with a triangular triangular shallow locking tooth 44 intermittently in the center in the longitudinal direction on one side. It is provided in a row. Both sides of the guide rail 4 in the longitudinal direction are thick portions 45 to increase the strength of the guide rail substrate 43.

  As shown in FIGS. 1 to 4, the buckle 6 has a square outer frame 61 with a cross bar 62 fixed at the center, and a stop pin 63 protrudes from the cross bar 62 so as to be pivotable. The cross bar 62 is pressed by two hook-like claws 52 protruding from the slider 5, so that the buckle 6 is integrated with the slider 5.

  The slider 5 is a hollow square box 51 having openings 53 and 54 on the left and right sides and the upper part, respectively. An opening 53 on the left-right side is a passage of the guide rail 4, and the guide rail 4 passes through the slider 5 through the opening 53. From the upper opening 54, a pressing head 551 and a neck 552 of the pushing piece 55 protrude. The pushing piece main body 553 is accommodated in the slider box 51 and can be moved up and down by the pressing of the pressing head 551. The bottom of the push piece main body 553 forms a U-shaped reversing portion 554, and is normally urged upward by a biped spring 56 provided between the lowermost part and the slider box bottom (FIG. 3). When the press head 551 is pushed down, the push piece main body 553 moves downward against the force of the spring 56.

  In a normal state, the tip 555 of the U-shaped reversing portion 554 contacts the locking teeth 44 of the guide rail 4 in the slider box 51, and the slider 5 is fixed at a specific position of the guide rail 4 (FIG. 3). (See (b)). In order to change this position, the press head 551 may be pushed down to release the contact between the tip 555 of the U-shaped reversing portion and the locking teeth 44 (see FIG. 4B). By doing so, the slider 5 becomes movable along the guide rail 4 again. If an appropriate position is selected and the pressing to the press head 551 is stopped, the slider 5 is fixed to the guide rail 4 again at that position.

  As described above, in this embodiment, the size can be adjusted only by pressing down the pressing head 551 and sliding the slider 5 in the direction in which the belt 2 (21, 22) is loosened. Therefore, when the wearer takes off the shoes, it is not necessary to remove the upper belt 22 from the buckle 6, and the foot can be removed from the belt only by pressing down the pressing head 551 and sliding the slider 5 in the direction in which the belt is loosened. .

  In this embodiment, the locking tooth 44 has a triangular prism shape and has an inclined side 441. When the tip 555 of the U-shaped reversing part of the slider 5 comes into contact with the inclined side 441 and slides on the inclined side 441, it slides, so that it contracts (to the left in FIGS. 3A and 4A). The upper belt 22 can be tightened by simply pulling it in the left direction.

  In the present invention, the belt length can be adjusted by selectively engaging the guide rail 4 and the slider 5. Needless to say, the belt length can also be adjusted by selectively engaging the adjustment hole of the buckle 6 with the upper belt 22. Therefore, since the belt length can be adjusted twice, the adjustment distance is longer than in the case where each belt is used alone.

  In the present invention, since the male and female snap buttons are not used, the belt must be removed from the buckle in order to divide the belt, and this is not possible unless consciously done. For this reason, it is not unsightly when the button is removed, and the operation of engaging the button becomes unnecessary.

  Furthermore, as shown in FIG. 2, in the present invention, the lower belt 21 is always positioned below the slider 5 and the buckle 6. Therefore, the slider 5 and the buckle 6 do not directly hit the foot of the shoe wearer.

It is a perspective view of women's shoes 1 using the size adjuster of the present invention. It is 2-2 sectional drawing of FIG. (A) is an enlarged plan view (natural state) of the adjustment tool 3, and (b) is a longitudinal sectional view. (A) is an enlarged plan view (during adjustment) of the adjustment tool 3, and (b) is a longitudinal sectional view thereof.
