Description

Slide fastener slider

The present invention relates to a slider used for a slide fastener.

As an example of the slider, there is a slider including a trunk that moves back and forth along a pair of element rows, a puller, and a cover that swingably connects the puller to the upper surface of the trunk (Patent Document 1, Patent Document). 2).

In the sliders disclosed in these two patent documents, the connection structure between the handle and the cover is as follows.
The slider handle disclosed in FIG. 9 of Patent Document 1 includes an annular frame portion through which a cover is passed, and a handle main body portion for operation extending from the frame portion. The frame portion includes a pair of arm portions extending in parallel from both sides in the width direction of the handle main body portion, and a shaft portion connecting the tip portions of the pair of arm portions, and the shaft portion is curved so that the ridge also expands in an arc shape. It has a shape. Further, the slider cover has a shaft holding groove for holding the shaft portion, and the handle rotates about 180 degrees in the front-rear direction around the shaft portion at the position of the shaft holding groove, and the shaft portion in the left-right direction. It swings at a predetermined angle along the curved shape.

On the other hand, the slider handle disclosed in FIG. 2 of Patent Document 2 is similar to the slider handle of Patent Document 1 and includes a handle main body portion and a frame portion, and the shaft portion of the frame portion is formed in a straight line. is there. Further, the slider cover has a shaft holding groove, and the shaft portion is rotatably held in the shaft holding groove, and the handle is about the shaft portion at the position of the shaft holding groove. It is designed to rotate 180 degrees.

In addition, the sliders described in the two patent documents employ a configuration in which the cover is elastically deformed when the cover is attached to the body.
For example, the body of the slider disclosed in FIG. 2 of Patent Document 2 includes a pair of mounting columns that protrude upward and front and rear of the upper surface thereof, and are attached to the front and rear sides of the front mounting column. The rear surface of the column is provided with a locking recess for stopping the cover. The slider cover spans between a pair of mounting columns and elastically deforms a plate-like cover main body portion, and a pair of locked portions that protrude from the front and rear end portions of the cover main body portion and are fixed to the pair of locking recesses. The convex part and the handle holding part which protrudes from the front-back center part of a cover main-body part and hold | maintains a shaft part between a pair of attachment pillars are provided integrally. The pulling handle holding portion is constituted by a pair of side wall portions that protrude in the width direction from the cover main body portion, and shaft holding grooves are formed in the pair of side wall portions. Note that the slider cover disclosed in FIG. 9 of Patent Document 1 has the same configuration as the slider cover disclosed in FIG. 2 of Patent Document 2.

Japanese Patent No. 4152254 Japanese Patent No. 4906644

However, when the cover is elastically deformed and attached to the body, the sliders of the above-mentioned two patent documents act so that the pair of side wall portions as the handle holding portion inhibits the elastic deformation. More specifically, for example, the slider disclosed in Patent Document 2 is continuous in a shape in which a pair of side wall portions are bent from the center portion in the front-rear direction of the cover main body portion, and the front-rear width of each side wall portion is in the cover main body portion. It is a form that becomes wider as it gets closer. And the cover body part becomes difficult to elastically deform, so that the front-and-rear width of the part which continues to a cover body part among side walls is large. Therefore, in order to facilitate the elastic deformation of the cover main body, it is desirable that the continuous portion of the cover main body and the handle holding portion (side wall portion) be as short as possible.

Moreover, the slide fastener using the slider disclosed in the above-mentioned two patent documents is attached as an example of an attachment mode so that it can be opened and closed horizontally with respect to the front surface of a rectangular bag or wallet as viewed from the front. Sometimes.

In the case of this attachment mode, when the front surface of the slider of Patent Document 1 is a vertical surface, the handle is not in a horizontal form parallel to the opening and closing direction, but in a form in which it is tilted or droops in the direction of gravity. It becomes. The reason for this is that the shaft portion is curved into an arcuate shape, and the swinging direction of the handle is present not only in the front-rear direction but also in the left-right direction. However, it is desirable for the appearance of the slider that the handle is parallel to the opening / closing direction, that is, a horizontal shape, and when the handle is inclined in the direction of gravity or hangs down, the appearance of the slider is poor. Become.

On the other hand, in the case of the same mounting configuration, the slider of Patent Document 2 is configured so that the handle is substantially parallel to the opening / closing direction when the front surface of the rod is a vertical surface. This is because the extending direction of the shaft portion is linear and the shaft portion is rotatably held in the shaft holding groove, that is, the swinging direction of the handle is only in the front-rear direction. It is because it restricts.

The present invention was created in view of the above circumstances, and its purpose is to make the cover easily elastically deformed when it is attached to the body while restricting the swinging direction of the handle to only the front-rear direction.

The first slider of the slide fastener of the present invention includes a body, a handle, and a cover that connects the handle to the upper surface side of the body so as to be swingable. The fuselage includes a pair of mounting pillars protruding upward and backward on the upper surface thereof, and a locking recess for stopping the cover on the front surface of the front mounting pillar and the rear surface of the rear mounting pillar. The pull handle includes a frame portion including a linear shaft portion serving as a center of swinging, and a pull main body portion for operation extending from the frame portion. The cover spans between a pair of mounting columns and is elastically deformable plate-like cover main body, a pair of protruding protrusions that protrude from the front and rear ends of the cover main body and are fixed to the pair of locking recesses And a handle holding portion that protrudes from the center portion in the front-rear direction of the cover main body portion and holds the shaft portion between the pair of mounting columns. The handle holding portion includes a base portion extending from the cover main body portion toward the body, and a pair of leg portions extending from the root portion and opening in the front-rear direction, and a pair of leg portions that are wider than the front-rear width of the base portion. And a shaft holding groove for rotatably holding the shaft portion between the pair of leg portions.

The first slider uses a cover in which the cover main body part and the handle holding part are integrated, but the present invention uses a cover in which the cover main body part and the handle holding part are separate. Also good.
That is, the second slider for the slide fastener of the present invention includes a body, a handle, and a cover, like the first slider. Also, the body is provided with a pair of mounting columns, like the body of the first slider, and is provided with a locking recess for stopping the cover on the front surface of the front mounting column and the rear surface of the rear mounting column. The puller is provided with a frame part including a shaft part and a puller main body part, similarly to the puller of the first slider. In addition, the cover includes a handle holding member that holds the shaft portion on the upper surface side of the body, and a cover member that spans the pair of mounting columns and fixes the handle holding member to the body between the pair of mounting columns. The holding member and the cover member are separated. The cover member spans between a pair of mounting columns and is elastically deformable, and a pair of projections that protrude from the front and rear ends of the cover body and that are locked to the pair of locking recesses Shall be provided. The trunk and the handle holding member include a positioning unit that positions the handle holding member between the cover main body and the trunk. The positioning portion includes an engaging portion formed on one of the body and the pull holding member and an engaged portion formed on the other, and the engaging portion is attached to the engaged portion. The handle holding member is provided with a shaft holding groove for rotatably holding the shaft portion on the surface facing the body.

The positioning portion may be anything that attaches the engaging portion to the engaged portion. To facilitate the attaching operation, the positioning portion is preferably as follows.
That is, the engaging portion is a convex portion, and the engaged portion is a concave portion into which the convex portion is fitted.

The concave portion and the convex portion may be formed on the body and the handle holding member separately. For example, the recess and the projection may be formed separately on the upper surface of the body and the lower surface of the handle holding member. Anyway.
That is, the concave portion and the convex portion are separately provided on each of the facing surfaces of one of the front side mounting column and the rear side mounting column and the handle holding member.

In the slider according to the present invention, in the case where the cover is a unit in which the cover main body part, the pair of latched convex parts, and the handle holding part are integrated, the handle holding part is longer than the front and rear widths of the base part. Since the width is wider, the cover body when attaching the cover body part to the pair of mounting pillars of the fuselage, compared to the one where the front and rear width of the base part is wider than the front and rear width of the pair of leg parts The part is easily elastically deformed. Further, since the linear shaft portion is rotatably held in the shaft holding groove of the handle holding portion, the swinging direction of the handle can be limited to the front-rear direction. Therefore, when the slide fastener is attached to the front of a rectangular bag or wallet when viewed from the front so that it can be opened and closed horizontally, the handle can be opened and closed even if the front of the bag is a vertical surface. It becomes a horizontal form almost parallel to the direction.

In the slider according to the present invention, when the cover has a cover member and a handle holding member as separate members, the cover holding member and the handle holding member are held in place because the handle holding member does not hinder the elastic deformation of the cover body of the cover member. Compared to the case in which the cover is integrated, the cover main body is more easily elastically deformed when the cover main body is attached to the pair of mounting posts of the body. Further, since the linear shaft portion is rotatably held in the shaft holding groove of the handle holding member, the swinging direction of the handle can be limited only to the front-rear direction. By the way, if only the cover main body member is fixed to the body without using the handle holding member, the swinging direction of the handle can be not only the front-rear direction but also the left-right direction, but the handle holding member is used together with the cover main body member. Thus, the swinging direction of the handle can be limited only to the front-rear direction.

Further, in the case where the slider of the present invention has an engaging portion as a convex portion and an engaged portion as a concave portion, the handle holding member can be positioned on the body only by fitting the concave portion and the convex portion. It becomes easy.
