Description

  The present invention relates to a suction cup integrated with a hook for hooking a small article, or a suction cup integrated with a small article, and more particularly, to an improvement of a suction cup that is mounted on a flat non-adsorptive surface by assembling small articles and tools.

  As a conventional technique of this kind, as shown in FIG. 7 and FIG. 8, the sucker generally used is a dom-shaped sucker main body 100 made of a flexible resin such as a vinyl chloride resin or a urethane resin that is flexible and stretchable. The top portion is composed of a protruding suction cup connecting portion 200 for assembling individual tools A such as hooks. The suction cup connecting portion 200 is not limited to hooks, and includes various daily goods and accessory accessories. These suction cup bodies 100 are also provided with suction on the non-suction surface B by providing suction openings 300 that stick to the non-suction surface B, which is another member.

  These suction cups have various diameters of the suction opening 300 and are diversified according to the use of the tool. The suction cup body 100 can be attached to the non-suction surface B serving as a mounting surface thereof. The pressure P is applied to the top, the suction opening 300 is pressed against the non-suction surface B, and the suction cup body 100 is crushed, the internal air is evacuated, and the pressure difference between the inside and the outside is created. The suction cup opening 300 can be adsorbed to the mating non-adsorbent surface B.

  However, in the case of the above-described prior art, the suction cup is strongly pressed and the suction cup body is crushed, and the air in the domed shape is gradually extracted from the joint gap between the non-adsorption surface and the suction opening. In order to maintain the pressure difference between the two, a slight gap is not allowed between the two joint surfaces. Especially, due to foreign matter or irregularities on the mounting surface, both cannot be in close contact with each other, the suction force is reduced, and the suction cup is the mounting surface. There are problems such as accidental dropout.

  In addition, because the sucker body is a soft resin vinyl chloride material with a dom shape, a restoring force that tries to return to the original shape after crushing the sucker body acts, so the suction cup is removed without knowing it. There are problems such as falling off the non-adsorbing surface.

  As long as the surface to be mounted is not a glossy surface such as tile, plus x chip, glass, mirror, etc., it is normal to start mounting, but even the degree of adhesion between these two cannot be confirmed, and the suction cup falls off sometime. There are many problems such as producing results that cause many accidents by dropping these suction cups.

  In order to solve this problem, the present invention proposes that the top portion of the suction cup body 1 such as a soft resin of a flexible stretchable material having a dome shape is individually formed as described in claim 1 in FIG. 1 and FIG. Protruding suction cup connecting part 2 for assembling tool A to be provided, and adjoining and adjoining suction opening 3 corresponding to the bottom of suction cup main body 1, a curved stretchable flexible part 4 is provided toward the outer periphery. Then, the opening end 5 of the flexible part 3 is brought into contact with the non-suction surface B by the suction operation by applying the pressing pressure P of the suction cup connecting part 2, and the sticking of the suction opening part 3 weeks is parallel to it. The two surfaces of the flexible part 4 that are divided into two parts, the sticking part with the opening end 5 are joined to the non-adsorbing surface B, thereby increasing the degree of close contact with the outside air and the flexible elastic material of the suction cup body 1 The elastic restoring force action of the It is intended to configure not to progress to the part 3 side.

  Next, as described in FIG. 3 and FIG. 4, the invention of claim 2 comprises a thin plate-like ring body 6 having a cushioning property such as soft resin or adhesive soft resin along the edge of the suction opening 3 described above. Adhering to the non-adsorbing surface B, the suction cup main body 1 is configured so that the adsorbing force can be increased depending on both the adhering adhesion and the adhering adhesion.

  Next, as described in FIG. 5 and FIG. 6, the invention in claim 3 is a suction cup body cap 7 which slides through the suction cup connection portion 2 provided on the top of the suction cup body 1 as an axis. The sucker body 1 is covered with the lever body 10 through the hole 7a, and the sucker connecting portion 202 is provided with a lever body 10 with a cam 9 which can be rotated by a fulcrum 8 connection, and the lever body 10 has a rotational force W. 3. The suction cup body 1 according to claim 1 or 2 is pressed by the non-stretchable suction cup body cap 7 through a so-called lever in which the cam 9 applies pressure to the side surface 7b of the suction cup body cap 7 by the suction work by contribution. It is a configuration to attach.

  With these additions, both the suction cup body 1 and the suction cup body cap 7 apply the rotational pressing force P toward the non-suction cup surface B, thereby preventing both the periphery of the suction opening 3 and the opening end 5 of the flexible section 4 from being removed. The adsorbing force is increased by adhering to the adhesive surface B.

  Since the present invention operates as described above, it has the following excellent effects. That is, as described in the first embodiment, even if there is a slight foreign matter or uneven gap between the suction cup and the non-suction surface, both the suction opening of the suction cup body and the curved flexure are attached in two parts. Since it is adsorbed individually on the surface, it is possible to provide a strong suction cup that can prevent the outside air from entering the suction cup body and that the suction cup does not accidentally fall off from the non-adsorption face.

  In addition, as described in the second embodiment, since the adhesive soft resin is adsorbed and attached to the attachment surface of the entire circumference of the one side of the suction opening portion in two parts of the suction opening portion of the suction cup body and the curved deflection portion, the attachment It is possible to provide a strong suction cup that is not affected by surface irregularities or foreign matter.

  Further, as described in the third embodiment, the suction cup body cap made of non-stretchable resin that covers the suction cup body is adsorbed to the mounting surface while pressing the suction opening of the suction cup body. It is possible to provide a strong suction cup in which the suction opening is not peeled off due to the restoring force of the soft resin of the main body, or the uneven surface or the rough surface does not fall off from the mounting surface.
