[Industrial applications]

 The present invention relates to a small article hanging device which is used, for example, for hanging and adjusting kitchen utensils, daily necessities, and other small items in a general household.

[0002]

[Prior art]

 Conventionally, as this kind of accessory hook, for example, as shown in FIGS. 8 to 10, a suction cup body a having flexibility and made of a rubber plate which is suction-held on a mounting surface W such as a wall surface made of tile, glass or metal. A connecting rod b is provided on the rear surface of the connecting rod b, and a pressing body c is arranged on the rear surface of the suction cup a so as to be inserted through the connecting rod b, and a hook body d for hanging various small objects on the connecting rod b is pinned. There is known a structure in which a cam projection f is formed on a hook body d, which is pivotally attached by e.

Then, as shown in FIG. 8, the suction cup body a is brought into contact with the mounting surface W, and in this contact state, the hook body d is laid down with the pin e as a fulcrum, and by this laying down, the action of the cam convex portion f is caused. The connection rod b is moved by, and the movement causes the peripheral portion of the suction cup body a to be pressed by the pressing body c while pulling up the center portion of the suction cup body a to bend it, and this bending deformation causes a gap between the attachment surface W and the attached surface W. The negative pressure state is used to obtain the adsorption action.

[0004]

[Problems to be solved by the device]

 However, in the case of the above-mentioned conventional structure, the suction cup body is a simple flat circular rubber plate in the normal state, and does not have a shape capable of exerting an adsorption action by itself. The structure is such that the suction action is generated only when d is laid down and the central portion of the suction cup a is pulled up through the connecting rod b, and the suction cup a is flexed and deformed from a flat shape to a dish container shape. The structure is designed so that the suction action is immediately released by simply raising the hook body d, and the ease of changing the mounting position with respect to the mounting surface is taken into consideration. In the case of this conventional structure, the suction action is exclusively performed. Since it depends only on the forced bending deformation of the suction cup body a due to the pulling of the connecting rod b, the suction action may be weakened by long-term use and the hanging load of small items to be applied may not be so large. Since the rod is formed as a separate body and its base end is adhered to the central portion of the suction cup, the suction of the central portion of the suction cup may become uncertain after long-term use. Since it is exposed, it is easy to receive an external force, the peripheral edge of the suction cup a is flipped, the above-mentioned flexural deformation collapses, and the negative pressure state is immediately released.

[Means for Solving the Problems]

 The present invention is intended to solve such a problem, and its gist is made of a flexible elastic synthetic resin or rubber, etc., and the elastic restoring action keeps a negative pressure state between the surface to be attached. A suction cup that is sucked and held on the surface to be attached, a connecting rod that projects from the back of the suction cup, and a pressing body that is provided in the back of the suction cup by being inserted through the connecting rod. , A hook body pivotably attached to the connecting rod by a pin so that the suction cup body is normally formed in a dish container shape and is elastically deformed by being pressed against a mounting surface. Is formed so that it can be adsorbed and held on the surface to be attached, and the base end portion of the connecting rod is embedded in the center of the suction cup body by resin molding so as to project. For small item hangings characterized by being formed in a shape that covers That.

At this time, it is desirable to form an annular convex portion on the inner surface of the pressing body that can press-contact the peripheral skirt of the suction cup body.

[0007]

[Action]

 When the suction cup, which is normally shaped like a dish container, is pressed against the mounting surface, the suction cup flexes and deforms against self-elasticity, and this bending elastic deformation causes air between the suction cup and the mounting surface. When the hook body is laid down in this state, a negative pressure is created between the mounting surface and the mounting surface due to the self-elasticity restoring action. The central part of the will be attracted and the adsorption force will increase. Further, since the base end of the connecting rod is embedded in the center of the suction cup and molded with resin, the center of the suction cup can be continuously and reliably moved, and the pressing body covers at least the peripheral edge of the back surface of the suction cup. Since it is formed in the, it will protect the sucker from external force.

At this time, by forming an annular convex portion on the inner surface of the pressing body, which is capable of press-contacting the peripheral skirt of the suction cup body, air invasion from the peripheral portion of the suction cup body is suppressed, whereby the suction action is continued. It will be done well.
