Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a handle of a slider used for opening and closing operations of a slide fastener, and allows for particularly accurate gripping and prevents fingertips from slipping off the handle. The present invention relates to a handle made like this.

[Prior art and its problems]

When operating a slide fastener, whether or not the slider slides smoothly is extremely important in determining its functionality.

The slider mentioned above is operated by grasping the handle attached to its upper end, but because the shape of the handle is extremely small, it is often difficult to grasp it firmly and accurately with the fingertips. By the way.

The above-mentioned drawbacks are even more pronounced when the handle is composed of only a single thin metal plate or a hard synthetic resin plate.

In order to solve these problems, the structure of the handle is made of a ring-shaped handle body and a rubber-like material large enough to fit into the ring-shaped part of the handle body, as shown in FIG. A structure has been proposed in which a plate-shaped anti-slip plate is combined, and the anti-slip plate made of a rubber-like material is fitted into a ring-shaped handle body.

The handle having the above-mentioned improved structure is extremely superior in that the frictional resistance of the rubber plate-like material prevents the fingertips gripping the handle from detaching from the handle, and effectively exhibits the anti-slip effect. However, the structure is such that a groove with a U-shaped cross section is formed along the entire circumference of the anti-slip plate, and a ring-shaped handle body is fitted into this U-shaped groove. As a result, it is difficult to fit the two together, making it unsuitable for mass production, leading to a rise in costs.

In addition, in order to facilitate the mating operation, it has been considered to widen the width of the mating groove, which has a U-shaped cross section, or to change the material of the anti-slip plate to a soft material. In some cases, drawbacks have been pointed out, such as the fact that the anti-slip plate may easily separate from the handle body because the material is soft.

[Purpose of invention]

The present invention was developed in view of the above-mentioned circumstances, and the method of combining the handle body and the anti-slip plate is extremely simple, and the combined product can maintain an extremely strong structure. It is an object of the present invention to provide a handle for a slider for a slide fastener.

Another object of the present invention is to provide a handle for a slider for a slide fastener that is highly mass-producible and can be manufactured at extremely low manufacturing costs.

[Key points of the idea]

The present invention consists of a handle body made of a plate-shaped body, which has an oval shape as a whole, and a fitting hole for attaching the upper grip part of the slider to the base end of the handle body. The tip portion excluding the fitting hole is formed as a hollow annular frame consisting only of the frame, and the hollow annular frame is made of a flexible rubber or soft synthetic resin plate. The key point of the invention is that the two female and male anti-slip plates, each having a shape that matches the shape of the hollow annular frame, have their abutting surfaces fitted into each other or integrated by adhesive means.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 is a handle body formed by a frame whose overall shape is an elongated circle, and is made of a thin metal plate,
Alternatively, it is constructed using a hard synthetic resin.

Reference numeral 11 denotes a hole for attaching a slider, which is formed in the base end of the handle body 1, and is formed in a relatively small circular shape.

Reference numeral 12 denotes a fitting portion of the anti-slip plate 2, which is formed into a hollow annular shape at the tip of the slider excluding the mounting hole 11.

This fitting part 12 is formed by the frame that constitutes the handle body 1, and on the inside along the peripheral edge there is a protrusion 13 for fitting that is slightly thinner than the wall thickness of the contour part. are integrally formed to protrude.

The anti-slip plate 2 is formed using a flexible rubber or soft synthetic resin plate, and is integrally formed by combining two pieces, a male plate 21 and a female plate 22 to which the male plate 21 is fitted and integrated. It is composed of

As illustrated in detail in FIGS. 3 to 5, the anti-slip plate 2 is formed by fitting the male plate 21 and the female plate 22 onto the peripheral edge of the contour of the male plate 21 and the female plate 22. Concave groove 23 into which the protrusion 13 can fit
is made possible to emerge.

The means for forming the groove 23 is to form a protrusion a on the abutting surface of the male plate 21, which is recessed slightly inward from the periphery of the protrusion a, and to This can be achieved by forming a recess b in 22 into which the protrusion described above can fit.

In addition, the male plate 21 and the female plate 22 are integrated by applying adhesive or the like to their mating surfaces (the surfaces where the protruding part a and the recessed part b come into contact), as illustrated in FIGS. 3 and 4. In addition to the case where the two are integrated, as illustrated in FIG. Various measures can be taken freely, such as forming a strong engagement part by forming the fitting periphery of the female plate 22 into a fitting flange b' having an inwardly inclined shape.

In the figure, 3 is a slide fastener, and 4 is a slider.

[Effect of idea]

The present invention configured as described above has the following effects.

(1) Since the anti-slip plate 2 is fitted and integrated into the grip part of the handle body 1, a firm grip can be achieved even when the handle body 1 is small in shape and has a structure that prevents the force of the fingertips from acting strongly.

(2) The anti-slip plate 2 is constructed by combining two plates, the male plate 21 and the female plate 22, and the means for attaching it to the handle body 1 is configured to clamp the handle body 1 from both the front and back surfaces, so that it does not attach to the frame. The mounting means is simply two component plates (male plate 21 and female plate 22).
The assembly process was extremely simple compared to conventional structures, as all that was required was to abut and integrate the two pieces (the two pieces) facing each other.

(3) The two male plates 21 and female plates 22 that are facing each other are made into one body by bonding their abutting surfaces with adhesive or by fitting the locking flange and the fitting flange, so that they are strong. It becomes possible to achieve integration.

(4) Manufacturing costs could be reduced.
