Description

Seat catch hook

The present invention relates to a seat catch hook, and more particularly to a seat catch hook that can be used by being attached to an arbitrary position of the sheet material without processing the sheet material itself.

To hang an object on a sheet material such as a tent or a blue sheet, or to fix a hook for tying a string or band, a method using a spring-type clip such as a clothespin or a sheet material There is a method of forming a through hole subjected to the above. The spring type clip is a clip that uses the repulsive force or restoring force of the spring, and is fixed by sandwiching the peripheral edge of the sheet material. In the method of fixing the hook to the sheet material using such a spring-type clip, there is a problem that if the hook is pulled with a certain force or more, the spring-type clip is easily detached.

On the other hand, in the method of forming a through hole in which a vinyl resin sheet or a cloth sheet is subjected to a perforation process, a string or a band can be directly connected to the perforation hole. It was necessary. For this reason, there existed a problem that the sheet material itself had to be processed. In addition, since the through hole is formed in the sheet material, it is difficult to change the fastening position when attaching the hook. For example, when the box is completely covered with the sheet material, it has been difficult to adjust the hook fastening position so that the four corners of the sheet material and the remainder cannot be left.

As a countermeasure, it is possible to hang a rope or string on the sheet material placed on the box, or to wrap and fasten the sheet material, but in such a method, a long rope is required, such as the corner of the box. Therefore, there is a problem that the sheet material is damaged by rubbing the portion in contact with the rope. Note that Patent Document 1 discloses a fastener that locks a sheet material to a frame using the elastic force of a resin material, but the fastener described in Patent Document 1 is similar to a spring-type clip. There was a problem that it was easy to come off.

Also, Patent Document 2 previously filed by the applicant of the present application describes a fastener that can be fixed at an arbitrary position of the sheet material. The fastener described in Patent Document 2 is formed with a catch holder in which a recess for holding the sheet material is formed on the inner peripheral surface, and an insertion portion for being inserted into the catch holder and engaged with the recess. It consists of a clasp button. The fastener can be fixed to the sheet material by pressing the fastening button into the catch holder with the sheet material interposed therebetween. However, in such a fastener, if the sheet material is to be securely fixed so as not to be easily removed, it is necessary to provide a lock key for pressing the insertion portion of the fastening button from the inside to the depression of the catch holder, There was a problem that the configuration would be complicated.

<Seat catch hook 100>
FIG. 1 is an exploded perspective view showing a configuration example of a seat catch hook 100 according to Embodiment 1 of the present invention. The sheet catch hook 100 is a fastener constituted by a ring 10 with a hook and a ring holder 20, and can be used by being attached to an arbitrary position of the sheet material 1. This figure shows a B-type ring 10 with a hook and an A-type ring holder 20 to be described later.

The ring holder 20 is a ring receiver in which an engagement groove 21 that engages with the hooked ring 10 is formed on the outer peripheral surface thereof. The engagement groove 21 is formed along the outer periphery. The sheet material 1 is a tent, a blue sheet, or the like, and plastic, cloth, paper, or the like is used for the sheet base.

The ring 10 with a hook is composed of a ring part 11, two hook parts 12, two neck parts 13, two operation handle parts 14 and two rod parts 15, and is made of an elastically deformable wire. The ring portion 11 is formed of a C-shaped ring that is engaged with the engagement groove 21 of the ring holder 20. Each hook portion 12 has a bent shape bent substantially toward the ring portion 11 side, and can be tied or hooked with a string or a band, while the distance from the center of the ring portion 11 is substantially the same.

Each neck portion 13 is a connecting portion that extends outward from both ends of the ring portion 11 and connects the hook portion 12 and the ring portion 11. Each operation handle portion 14 is an operation portion for operating the ring 10 with a hook when attaching and detaching, and has a bent shape in which a wire is bent.

The engagement groove 21 is formed so as to surround the cavity 24, and its cross-sectional shape is substantially V-shaped with a predetermined depth V3. That is, the engagement groove 21 has two groove walls 21b each having an inclined surface that makes a round on the outer peripheral surface and is inclined so as to become narrower as the groove width approaches the groove bottom 21a. Therefore, in this engagement groove 21, the width V1 of the groove opening is wider than the width V2 of the groove bottom 21a.

Since the engaging groove 21 is formed so as to surround the cavity 24, the ring with hook 10 can be engaged with the ring holder 20 at an arbitrary angle. Further, by making the engagement groove 21 have a substantially V-shaped cross section, the hooked ring 10 is engaged with the engagement groove 21 with the sheet material 1 interposed therebetween, regardless of the thickness of the sheet material 1. The hooked ring 10 can be firmly engaged. That is, if the thickness of the sheet material 1 is small, the sheet material 1 is sandwiched in the deeper portion of the engagement groove 21, and the thicker the thickness is, the smaller the portion is sandwiched in the shallower groove side. Even if it is thin or thick, the hooked ring 10 can be firmly engaged.

Such a ring holder 20 is molded using metal or resin. For example, it is formed by cutting a resin pipe having a strength that can withstand use into a necessary width. Here, an example has been described in which the groove walls 21b on both sides of the engagement groove 21 are both inclined surfaces, but only the groove wall 21b on one side of the engagement groove 21 is an inclined surface.
