Abstract

(57) [Summary] [Purpose] The suction plate has a large suction force and can be fixed with high reliability so that the inner surface of the suction plate can be sufficiently negatively pressured when it is mounted on a wall surface. [Structure] An air vent hole 2 penetrating the inner and outer surfaces of a disc-shaped suction cup body 1 having a recess 1a on the inner surface is formed, and an airtight plug 3 that can be inserted into the air vent hole 2 in an airtight state is connected to a connecting cord. It is assumed that it is connected to the suction cup body 1 by means of 4. Since the inside and outside of the suction cup can be connected,
At the time of pressing, air is not accumulated in the recesses on the inner surface, and the adsorption force is efficiently exhibited.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suction plate used as a fixture that can be sucked onto a smooth surface such as glass or tile.

[0002]

[Prior art]

 Generally, a suction cup is used to temporarily attach household items, office supplies, etc. to the glass surface or tile surface without damaging them.

As shown in FIG. 3, the suction plate 10 is made of a relatively soft synthetic resin such as polyvinyl chloride or polyethylene, or rubber, and has a disk shape having a recess 11 on its inner surface. A locking portion 12 with a ring for attaching a hook or the like is integrally formed on the surface.

When such a suction plate is used, the inner surface is pressed so as to be in close contact with a smooth wall surface. However, the suction force exerted after the pressing force is released depends on the synthetic resin or rubber. It is exerted by creating a negative pressure recess 11 on the inner surface by the force that tries to return to the shape.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned conventional suction cup, when it is pressed against the wall surface, air cannot be sufficiently escaped from the peripheral edge, and a small amount of air remains in the recess on the inner surface. In addition, the remaining air is in a state of being pressurized to the atmospheric pressure or more at the time of pressing, so that when the pressing force is released thereafter, there is a problem that the recess on the inner surface cannot be made sufficiently negative pressure. .

Therefore, the present invention solves the above-mentioned problems of the conventional suction cups, and makes the suction cups capable of sufficiently reducing the inner pressure thereof, that is, capable of efficiently exhibiting the suction force. Is an issue.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, an air vent hole penetrating the inner and outer surfaces is formed in a suction plate made of soft synthetic resin or rubber, and an air vent hole that can be inserted from the outer surface side is formed in the air vent hole. It adopted a structure that was equipped with a stopper.

[0008]

[Action]

 In the suction plate of this invention, air can be smoothly released from the recess of the inner surface by opening the air vent hole and pressing the suction plate against the mounting surface while the inner and outer surfaces of the suction plate are in communication. Therefore, it becomes easy to press without leaving air in the recess of the inner surface, and even if some air remains at the time of pressing, this air is not pressurized.

For this reason, when the airtight plug is inserted into the air vent hole to release the pressing force, the force of the synthetic resin or rubber to return to its original shape acts efficiently to reduce the negative pressure on the inner surface, resulting in high suction. Show strength.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, in the first embodiment, a disc-shaped suction cup body 1 made of soft polyvinyl chloride and having a recess 1a on the inner surface is provided with an air vent hole 2 penetrating the inner and outer surfaces thereof. Is forming. An airtight plug 3 made of the same material as that of the suction cup body 1 which can be inserted into the air vent hole 2 in an airtight state is connected to the suction cup body 1 by a connecting cord 4 and attached. A ring 5 for attaching a hook or the like is integrally provided on the top of the suction cup body 1.

In the above-described first embodiment, the suction cup body 1 is formed in a bowl shape having a relatively deep recess 1a to enhance suction performance. It can release air smoothly and can be installed with a small pressing force.

When the suction cup is removed at an appropriate time, the airtight plug 3 can be pulled out and air at atmospheric pressure can be quickly introduced into the inner surface to release the suction force. Further, since the airtight plug 3 is connected to the suction cup body 1 by the connecting string 4, the airtight plug 3 can be easily attached without removing it when it is attached to a wall surface or the like.

As shown in FIG. 2, the second embodiment is made of rubber and is relatively large, and a bellows 7 is formed on the peripheral side surface of the suction cup body 6 formed in a deep bowl shape, and the bellows 7 is formed at the center of the top surface. The air vent hole 2 is formed. The airtight plug 8 inserted into the air vent hole 2 is integrally formed with a ring 8a for attaching a hook (not shown) or the like.

Since the second embodiment has the air vent hole 2 similarly to the first embodiment, air easily escapes from the inner surface through the air vent hole 2 when pressed even though it is a relatively large suction plate. Moreover, since the bellows 7 can be expanded and contracted for installation, it can be installed with a smaller pressing force. Further, since the airtight plug 8 is integrally provided with a ring 8a for locking a hook (not shown) or the like, this portion is easy to hold and can be easily inserted into the air vent hole 2.

In the above embodiments, the suction cup has an outer diameter that is circular when viewed from above, but may be provided in various shapes such as an ellipse or a polygon having a shape of a triangle or more. Of course.

[0017]

【effect】

 As described above, according to this invention, the suction plate is formed with the air vent hole penetrating through the front and back surfaces thereof, and the air vent hole is provided with the airtight plug. It is easy to press the air without leaving the inside of the place, and the inner surface is sufficiently negatively pressured when it is adsorbed, so that the adsorption force can be efficiently exerted and the adsorption plate can be fixed with high reliability. There is an advantage to be.
