Description

  The invention according to the claims relates to a slide fastener capable of fixing the movement of a handle attached so as to swing with respect to a pillar portion, and a boot to which such a fastener is attached.

  In general, the pull fastener of the slide fastener is attached so as to be able to swing with respect to the slider in order to facilitate pulling in either direction when opening and closing the element (a pair of meshing portions called “serving teeth”). For this reason, for example, when fasteners are attached to the inside of boots (the sides facing each other), the handle may hang around while walking, etc., and may be caught by the opposite leg or stocking, or the left and right handle may touch. . In such a case, there is a tendency that the stocking is torn or the handle is broken.

A known technique for fixing a pullable handle is disclosed in Patent Document 1, for example. As shown in FIGS. 5A to 5C, a slide fastener 1 ′ described in Document 1 includes a column portion 2 ′ fixed to the upper surface of a body portion 4 ′ of a slider 10 ′ that opens and closes an element 20 ′. On the other hand, the handle 3 'is connected so that it can swing. Further, a rubber or resin cover 5 'is attached to the handle 3'. The round hole 5a ′ formed in the cover 5 ′ has a size that matches the projection 6a ′ of the projection plate 6 ′ separately provided on the clothes 30 ′ or the like, and the round hole 5a ′ is impossible for the projection 6 ′. By fitting (so-called snapping), the handle 3 'can be fixed.
JP 2001-204514 A

  In the case of the fastener described in Patent Document 1, in order to fix the movement of the handle, it is necessary to separately provide a locking portion for fixing to clothes or the like. It is also necessary to attach a rubber or resin cover as described above to the handle. Therefore, an extra manufacturing process and cost are required.

  In view of these points, it is an object of the present invention to provide a new slide fastener that can prevent the pulling of the handle by a simpler and less expensive structure.

  In order to solve the above-mentioned problem, a slide fastener according to the present invention has a slider attached to a slider body for opening and closing an element, and a handle is attached so as to swing in a state of being connected to a column part. Or it is characterized by being configured so that the above-mentioned pull handle can be snap-stopped to the pillar portion (that is, a stop method in which the pull handle is pressed and stopped, forcibly fitted).

  With such a slide fastener, the handle can be fixed by a simple method of snapping to the body or the column portion of the slider. Since it is not necessary to provide a component for fixing the handle outside the fastener such as clothes, the structure is particularly simple and can be manufactured easily and inexpensively. Moreover, since the external appearance is simple, it is convenient when the fastener is not desired to stand out.

The slide fastener according to claim 2 is provided with a hole in the handle for the connection with the column part, and a portion having a cross-sectional dimension larger than the hole is formed near the end of the column part. The puller is snapped to the vicinity of the end of the column when it has moved beyond that portion having a large cross-sectional dimension. For example, in FIG. 4, the cross-sectional dimension A of the pillar 2 is larger than the cross-sectional dimension C of the hole 31 of the handle 3, and the handle 3 is snapped when moving beyond the dimension A.
When the handle is moved, in the above-described portion having a large cross-sectional dimension, the hole of the handle touches and catches the portion, and the handle cannot be moved further unless a force is applied. However, if a sufficient force is applied, elastic deformation occurs between the handle and the column portion, and the handle crosses that portion and moves to the position ahead. In this way, the puller is simply snapped and fixed near the end of the column by applying a slightly larger force. Further, with such a slide fastener, it is not necessary to bother to provide components (such as dedicated protrusions and holes) for snapping.
In the state where the handle is fixed, the fixed state of the handle is not released unless a force of the same magnitude is applied in the opposite direction to the handle. Therefore, according to this slide fastener, there is an advantage that the handle can be securely fixed.

In the slide fastener according to claim 3, a portion having an outward projecting portion as a portion having a large cross-sectional dimension is formed in the vicinity of the end portion of the column portion, and a handle is formed between the projecting portion and the body. It is characterized in that a space in which can be accommodated is provided. In the example of FIG. 4, the space is provided between the lower surface 8 b of the protruding portion 8 and the upper surface of the body portion 4.
With the slide fastener having such a configuration, the handle that has moved beyond the protruding portion having a large cross-sectional dimension is accommodated in the space, and is stably fixed at a position along the trunk. In that state, the pulling handle hardly protrudes outwards, is hardly noticeable, and does not easily come off from the fixed state, which is extremely preferable.

The slide fastener according to claim 4 is restrained by the column part and the body and does not move in any direction when the handle is in the space provided between the protrusion and the body. It is characterized by that.
With such a slide fastener, the handle can be fixed particularly securely when the handle is inserted into the space. In this state, the handle does not sway or rattle with respect to the body or the column portion, so that there is an advantage that wear on the handle is less likely to occur.

The slide fastener according to a fifth aspect is characterized in that the slide fastener is attached to opposing side portions (inner sides) of a pair of boots.
Such a slide fastener can be fixed so that the handle does not hang when the boot is worn, so that it is possible to prevent the handle from being caught by the stockings or from being damaged due to contact between the handles.

The boot of the invention according to claim 6 is characterized in that any one of the above slide fasteners is attached to the left and right opposing side surface portions (inner sides).
In such a boot, since the fastener pull can be fixed, it is possible to prevent the pull handle from being caught on the opposite leg or stocking or in contact with the other fastener pull during walking. Therefore, in this boot, it is possible to eliminate the inconvenience that the stocking is torn or the handle is damaged.

According to the slide fastener of the invention according to the claims, the handle can be easily fixed by snapping the body or the column portion of the fastener itself. Since it is not necessary to provide a component for fixing the handle outside the fastener such as clothing and boots, the manufacturing process and appearance are simple.
If a space in which the snapped handle can be accommodated is provided between the vicinity of the end of the column and the body, there is an advantage that the handle is stably fixed at a position along the body.
When the handle is constrained by the pillar or torso so that it does not move in any direction when it fits in the above space, the handle can be securely fixed so that it does not shake or rattle, thereby reducing wear on the handle. There is also.
When the slide fastener of the present invention is attached to the opposite side portions (each inside) of the boot, the handle is not caught by the stocking and the stocking is not torn, or the handles are not touched and damaged.

A slide fastener as an embodiment of the invention will be described with reference to FIGS.
FIG. 1 is a perspective view showing a state in which the pulling handle 3 of the slide fastener 1 is released (in a swinging state), FIG. 2 is a plan view of the pulling handle 3, and FIG. FIG. 4 is a sectional view taken along line IV-IV in FIG. 3.

  As shown in FIG. 1, the slide fastener 1 includes a slider 10 composed of a column part 2 and a body part 4, a handle 3 attached so as to be able to swing with respect to the column part 2, and an element that can be opened and closed by the slider 10. (Not shown).

  The body part 4 has a structure similar to that of a general fastener and includes a rail part 5 for guiding an element. The rail portion 5 has a tape groove 6 through which a tape (not shown) to which the element is attached passes, and the shoulder opening 7 of the tape groove 6 has a width (interval) that allows the element to pass through. In FIG. 1, the element can be closed by pulling the pull handle 3 to the right side (front side, the side of the shoulder opening 7), and conversely, pulling the pull handle 3 to the left side (back side, the side opposite to the shoulder opening 7). And you can open the element.

  The column part 2 has a handle holding part 2a in the vicinity of the center, and the part 3 supports the handle 3 so that it can swing around the base end part 3a. The pull 3 has a hole 31 for connection with the pillar 2 near the proximal end 3a (see FIG. 2). Further, another hole 32 is provided near the tip 3b of the pull handle 3 so that the user can easily apply a force of pulling with a finger.

  The column portion 2 has a protruding portion 8 that protrudes in a curved shape at the upper end surface on the opposite side (rear end) of the shoulder opening 7. The length A from the tip 8a of the protruding portion 8 to the handle holding portion 2a (the point of contact with the handle 3 when the element is opened) is such that the handle 3 can be snapped (it cannot be caught unless force is applied). ) Is set to be longer than the internal dimension C in the longitudinal direction of the hole 31. The length B from the end of the column part 2 on the shoulder opening 7 side to the handle holding part 2a (the point of contact with the handle 3 when the element is closed) is shorter than the length A and the internal dimension C. This is to prevent the handle 3 from being caught by the pillar portion 2 when the element is closed. Further, the width D of the hole 31 of the handle 3 is set to a dimension such that the inner side surface 31a of the hole 31 is along the side surface of the column part 2, and wear due to the backlash of the handle 3 from side to side is prevented.

  As shown in FIG. 4, the attachment position of the lower part of the rear end surface of the column part 2 (the lower part of the projecting part 8) to the body part 4 is 2 to 3 mm inside (closer to the shoulder opening 7) from the rear end 4 a of the body part 4. A substantially U-shaped space 9 is formed between the upper surface of the body portion 4 and the protruding portion 8. The distance between the upper surface of the body portion 4 and the protruding portion 8 is set to a dimension that allows the inner end portion 3c of the handle 3 to be sandwiched and fixed. Furthermore, a downwardly facing bulge is provided on the lower surface 8b of the protruding portion 8 so that the protrusion 3 can be securely fixed in a form of pressing the handle 3.

  As the material of the handle 3, a flexible high-strength material (for example, resin or FRP) is easier to handle and less likely to break than a hard metal or the like.

  In the slide fastener 1 configured as described above, when the handle 3 is tilted to the rear end 4a side of the body portion 4, the inner edge portion 3c of the hole 31 is applied to the protruding portion 8, and the front end portion 3b is pressed against the element side, A contact point between the proximal end portion 3a of the handle 3 and the handle holding portion 2a serves as a fulcrum, and can be hooked on the protruding portion 8 like a snap stop. As shown in FIG. 3, when the inner edge 3 c exceeds the tip 8 a, the handle 3 is slid in the direction of the shoulder opening 7, and the inner edge 3 c is fitted into the space 9 and fixed. As described above, since the length A of the column portion 2 is longer than the length C of the hole 31 and the inner edge portion 3c is sandwiched between the protruding portion 8 and the body portion 4 in the space 9, the handle 3 can be reliably fixed. .

  When releasing the fixing, reverse the procedure, first pull out the inner edge 3c of the handle 3 from the space 9 and then force the tip 3b of the handle 3 away from the element (upward in FIGS. 3 and 4). And the inner edge 3c may be removed from the protrusion 8.

  The slide fastener 1 can be easily manufactured at low cost because the handle 3 can be prevented from wobbling only with basic components of the fastener. In particular, it is optimal to use the slide fastener 1 on the inside of a boot where the swinging of the pulling hand may cause damage to the pulling hand or the stocking. Of course, the present invention can be applied to other uses where it is desired to avoid the shaking of the handle.

  In addition, the shape of the column part and the handle introduced above and the dimensions of each part may be determined within a range not departing from the gist of the invention, and are not limited to the above.

It is a perspective view which shows the state which released the handle 3 about the slide fastener 1 as one Embodiment of invention. It is a top view of the handle 3. 2 is a perspective view showing a state in which a handle 3 is fixed with respect to the slide fastener 1. FIG. It is IV-IV sectional drawing in FIG.
