造に関する。DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a hollow cylindrical protrusion of an engaging member made of synthetic resin is engaged with a hole of a hook member while penetrating the base fabric, and the protrusion is outwardly This invention relates to a hook attachment structure for fixing a hook to a deformed base fabric.

形が良好、且つ確実に行えない欠点があつた。 Conventionally, when creating such a hook attachment structure, an engaging member having a solid protruding portion was used, so the plastic deformation resistance to the outside of the tip portion was extremely large and the root of the protruding portion ( The impact stress of the plastic deformation hammer concentrates on the base (the base), causing the root to bulge outward, which has the drawback that outward plastic deformation of the tip cannot be performed properly and reliably.

部材の遊離をまねく欠点があつた。 In order to solve this problem, it has been proposed to use an engaging member that has a hollow cylindrical shape for the protrusion, as shown in Japanese Utility Model Publication No. 39-11309. The outer circumference of the upper end of the part is steeply tapered to reduce the wall thickness in the radial direction, and the upper end is plastically deformed outward to form an internal head that engages with the hook member. There is a strong tendency to return to the shape before deformation, and there is a drawback that the connection between the hook member and the engaging member becomes loose. In other words, synthetic resins inherently tend to return to their original shape, and when exposed to high heat, such as when ironing or drying in a dryer, they tend to soften and return to their original shape. In other words, when the hook is released, the hook member of one hook pulls the hook member of the other hook, and this pulling force is applied to the inner head, so that the inner head returns to its original shape. However, since the internal head deformed by the hammer is thin and the protrusion is cylindrical, the internal head easily deforms elastically. As a result, the connection between the hook member and the engaging member becomes loose, resulting in a drawback that both members come loose.
本発明は、このような欠点がなく、強度的に優

端部には全周にわたつて内方へも塑性変形されて
突起部分内方の筒状空間上部開口を気密に閉塞す
る蓋状補強部分を具えている点にある。 The structural feature of the present invention for achieving this object is that the hollow cylindrical protrusion of the synthetic resin engaging member is passed through the base fabric, and the hook hole is located on the opposite side of the base fabric. In the hook attachment structure in which the hook is fixed to the base fabric by engaging with the tip of the protrusion and plastically deforming the tip of the protrusion outward, the radial wall thickness of the hollow cylindrical protrusion is equal to the thickness of the base. The lid-like reinforcement part is formed almost identically from the top to the top end, and is plastically deformed inward over the entire circumference to airtightly close the upper opening of the cylindrical space inside the protrusion. The point is that it has the following.

る。 In other words, the innermost part of the upper end of the protrusion is plastically deformed inward over the entire circumference, and the innermost part of the deformation is in complete airtight contact, forming an inward tsuba, so to speak. When this inner lid-shaped reinforcing part tries to return to its original shape, the part plastically deformed outward (inner head) exerts a kind of holding rod function to counteract the force of the restoring force. By doing so, the potential return stress of the outwardly plastically deformed part can be successfully eliminated and the desired shape can be reliably maintained for many years.Furthermore, when the hook is released, the internal head is The tensile force also acts to reduce the diameter of the upper end of the protrusion, which also makes it easier for the inner head to return to its original shape. In other words, it becomes easy to be elastically deformed, but in this invention, the lid-shaped reinforcing portion does not cause the diameter of the upper end of the protrusion to be reduced, and from the above two points, the return of the internal head is ensured. It can be prevented.
更にいま一つは、突起部分の肉厚がほヾ同一で
あるために、従来構造に較べて内部頭も蓋状補強
部分も共に厚肉に形成できるため、外部応力につ
まりホツク離脱時の引つ張り力に対しても強固に
対抗でき内部頭のもどりを良好に防止できる。 Furthermore, since the wall thickness of the protruding parts is almost the same, both the internal head and the lid-shaped reinforcing part can be made thicker than in the conventional structure, so there is less stress caused by external stress and pull when the hook detaches. It can strongly resist tensile forces and can effectively prevent the internal head from returning.

有利なものである。 In this way, in the present invention, the return of the internal head, that is, elastic deformation, can be effectively prevented, and the connection between the hook member and the engaging member can be maintained firmly for many years, and the hook can be attached to a base fabric with excellent strength. It can provide structure. By the way, the hook of the present invention can withstand a tensile force of about 11 kg, but it was found through experiments that the practical product described in the above-mentioned document had a maximum tensile force of 4 kg. Furthermore, since the internal return is difficult to occur, there is no need to provide the hook member with any special means for preventing the internal return, which is advantageous from a structural standpoint.
