Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a releasable slide fastener used for attaching various sheets, particularly sheets for construction and civil engineering, in a removable manner.

[Conventional technology]

The well-known releasable slide fastener has a butterfly pin on one end of the left and right fastener stringers.
The other side is provided with a separable fitting to which a box rod and a box body are attached. To close this slide fastener, pass the slider through the box rod and bring it into contact with the box body, then pass the other butterfly pin through the slider and insert it into the box body, and while maintaining this state, slide the slider upward. The slide fastener can be closed and opened very easily, since all you have to do to open it is to bring the slider into contact with the box body as described above and then pull out the insert pin from the box body and the slider. . However, these releasable slide fasteners are only manufactured and sold as relatively small slide fasteners used for clothing such as jumpers and jackets, and are not used for large slide fasteners used to open and close civil engineering sheets or construction sheets. The reality is that releasable slide fasteners are not manufactured and sold because there is not much demand for them.

[Problem that the invention seeks to solve]

For this reason, when joining and separating civil engineering sheets and construction sheets, both sheets had to be tied together with strings, making joining and separating them troublesome.

The object of the present invention is to provide a releasable slide fastener used in fields with low demand such as civil engineering sheets and construction sheets, which can be easily manufactured at low cost.

[Means for solving problems]

Either one of the female surface fastener and the male surface fastener constituting the surface fastener is fixed to each end of both left and right fastener stringers, and the other surface fastener is fixed to each end of both fastener stringers. The above problem is solved by separably engaging both of the surface fasteners.

〔Example〕

As shown in the drawings, the releasable slide fastener according to the present invention is composed of a pair of fastener stringers 1 and 2, a slider 3, and a surface fastener 4. The fastener stringers 1, 2 have a raised edge 6 along the entire length of one side edge of the tape 5, and an element 7 is attached to this raised edge 6.
is attached, but the end of the raised edge 6 is provided with an empty edge 8 to which no element 7 is attached. The hook-and-loop fastener 4 is composed of a female fastener 4a having a large number of loop-shaped barbs protruding from the base surface of cloth, etc., and a male fastener 4b having a large number of hook-shaped barbs projecting from the base surface. By joining the male surface fastener 4a and the male surface fastener 4b facing each other, the male and female double-sided fasteners 4a, 4
b are designed to be engaged, and can be separated by pulling the engaged male and female double-sided fasteners 4a and 4b apart.

The slider 3 has an element guide section at the center of the front end of parallel upper and lower wings, and has a handle 9 on the upper wing. Either the female fastener 4a or the male fastener 4b constituting the hook-and-loop fastener 4 is fixed to both the front and back sides of the tape at each end of the fastener stringers 1 and 2. In this case, as shown in FIG. 2, one of the hook-and-loop fasteners is attached from the end of the tape to a length extending over a plurality of elements 7. Furthermore, one fastener stringer 1
The other surface fastener is superimposed and interlocked with the tape so that it overlaps with one of the surface fasteners on the front and back sides. It is formed so as to mesh with both sides of each hook-and-loop fastener attached.

Incidentally, as shown in FIG. 4, the surface fastener 4 may be provided only on one side of the fastener stringers 1 and 2, or as shown in FIG.
Even when all the elements are present at each end of both fastener stringers 1 and 2, surface fasteners can be provided to make a releasable slide fastener. Also, Fuasuner stringer 1, 2
A slider 3 is provided at the end opposite in the longitudinal direction to the end to which the hook-and-loop fastener 4 is attached.
It is necessary to provide a means to prevent the fastener stringers 1 and 2 from coming off.
A top stopper (not shown) is provided at the top, or a hook and loop fastener 4 is provided in the same manner as in the structure described above. Furthermore, as shown in FIG. 1, a stopper 10 having a "Ja" shape may be inserted.

When closing the releasable slide fastener of the above embodiment, both fastener stringers 1 and 2 are
After aligning the ends with the hook-and-loop fasteners 4 parallel to each other with their empty edges 8, 8 facing each other, and inserting the slider 3 through the ends to engage both elements 7, 7, both fastener stringers The other surface fastener is engaged over both sides of each surface fastener 4 constituting the surface fastener 4 fixed to the ends of the two ends. Due to this meshing of the surface fasteners 4, both the fastener stringers 1,
2 are integrally connected and meshed elements 7,
This reliably prevents separation of 7. Next, when separating, the meshing male and female double-sided fasteners of the hook-and-loop fastener 4 are separated and the slider 3 is pulled out.
2 can be separated.

Incidentally, when using the releasable slide fastener according to the present invention, it is preferable that the end portion to which the hook-and-loop fastener 4 is attached protrudes from the adherend.

〔Effect of the invention〕

The releasable slide fastener according to the present invention fixes either one of the female surface fastener and the male surface fastener constituting the surface fastener to each end of both fastener stringers,
The other surface fastener is separably engaged with both of the surface fasteners fixed to both fastener stringers, and when closing the slide fastener, the slider is passed through both fastener stringers, and then the male and female surface fasteners are separated. The closed state of the closed slide fastener is maintained by simply engaging the double-sided fasteners with each other.
In addition, when it comes to separating, it can be opened simply by separating the male and female double-sided fasteners that are engaged with each other. You can easily make releasable slide fasteners without using a press molding machine or a releasable fitting attachment machine, and even if you are producing in small quantities, you do not need particularly expensive machinery. Therefore, it can be produced at low cost.

Furthermore, since the hook-and-loop fastener is provided so that it can be widely fixed to the flat portions at the ends of both fastener stringers, if the male and female double-sided fasteners of the hook-and-loop fastener are engaged, each end of both fastener stringers will not be misaligned. Another advantage is that it is possible to reliably prevent the elements that are integrally connected to each other and meshed from the ends of both fastener stringers from separating.
