[0008]

[Action]

 In the suction cup device of the present invention, when the passage opening / closing plug as shown in FIG. 1 is used as the passage opening / closing member, when the handle 2 is pushed downward, the suction cup 3 is pressed against the tile surface 121, and between them. Some air is discharged from between the suction cup 3 and the tile surface 121, and is also discharged from between the plug hole and the plug 5 through the ventilation pipe 41. As shown in FIG. 2, the rubber disc 7 may be pushed in order to positively discharge air from between the plug hole and the plug 5.

Simultaneously with the discharge, the valve surface comes into close contact with the upper end of the ventilation pipe 41 to block air. Since the result tile 12 is sucked and the suction state continues, the tile can be taken out. Then, when the suction force of the suction cup 3 is released, as shown in FIG. 2, the central portion of the rubber flat plate 7 provided at the small-diameter end of the passage opening / closing plug 5 is pushed to release the sealing of the air pipe 41. The suction of the suction cup 3 is released by ventilating the outside, and the tile 12 is separated from the suction cup 3.

When the rotary valve 51 is used as the passage opening / closing member, the ventilation pipe 53 in the rotary valve 51 is blocked from communicating with the outside with the ventilation pipe 41 with the lever 54 raised. Further, at the position where the lever 54 is pushed downward, the ventilation pipe 53 and the ventilation pipe 41 in the rotary valve 51 are communicated with each other so as to be airtight or released.

Further, when the piston type valve 52 is used as the passage opening / closing member, the vent pipe 53 provided in the valve 52 can be communicated with the vent pipe 41 by pulling the head portion 55 of the valve 52. The ventilation pipe 53 provided inside the valve 52 communicates with the ventilation pipe 41 by shutting off and pressing the head portion (button) 55 of the valve 52. Also in the case of the rotary valve 51 and the piston type valve 52, air may be exhausted from between the suction cup 3 and the tile surface 121 similarly to the passage opening / closing plug.

【Example】

 Examples of the present invention will be described below in more detail with reference to the drawings, but the present invention is not limited to these examples.

Embodiment FIG. 1 is a sectional view of a suction cup device according to the present invention, in which 1 is a body portion and 2 is a handle formed by an end portion of the body portion 1 made of hard rubber. .. At the other end of the body portion 1, there is a suction cup 3 made of soft rubber, which is adhered with an adhesive. A passage opening / closing plug 5 made of hard plastic is provided near the center of the body portion 1 as a passage opening / closing member.

The suction cup 3 and the body portion 1 may be integrally formed of the same material, or both may be formed of different materials. When the suction cup 3 and the body portion 1 are integrally formed, preferred materials include butadiene rubber, ethylene propylene rubber, natural rubber, isoprene rubber, high density polyethylene and polypropylene.

The surface of this passage opening / closing plug 5 can shut off air by contacting the end of the ventilation pipe 41 communicating from the air port 4 of the suction cup 3 to the upper portion, and the passage opening / closing plug 5 , Has a conical shape, and is inserted and arranged at right angles to the axial direction of the body 1. A disc-shaped flat plate 7 made of rubber is fixed to the end of the small diameter portion of the passage opening / closing plug 5. For this fixing method, any means such as an adhesive or a screw may be used. A screw is preferable.

Further, the passage opening / closing member has a slight distance, that is, a gap between the inner surface of the insertion hole provided in the body portion and the surface of the passage opening / closing plug 5, so that when the tile 12 is sucked. Internal air can be discharged from the gap. When the suction cup and the body are made of different materials, the connection between them may be a commonly used fixing method, for example, screws or adhesives may be used for fixing.

Next, a method of using the suction cup device will be described. When the suction cup 3 is applied to the tile 12 and the handle 2 is pushed, the suction cup 3 is pressed and the air between the tile 12 and the suction cup 3 is blown through the ventilation pipe 41. Then, it is discharged to the outside through the gap between the surface of the passage opening / closing plug 5 and the inner surface of the insertion hole of the body portion 1. As a result, the tile surface 121 and the suction cup surface 31 come into close contact with each other, and at the same time, the end portion of the ventilation pipe 41 and the plug surface come into close contact with each other to block the flow of air. Then, the tile 12 is adsorbed to the suction cup 3, and the tile 12 can be taken out by lifting the handle 2.

After removing this tile, when removing the tile from the suction cup, as shown in FIG. 2, the central portion of the rubber flat plate 7 provided on the passage opening / closing plug 5 is pushed to open / close the passage. The close contact between the surface of the plug 5 and the inner surface of the insertion hole of the body portion 1 is released, and a gap is created between the tile 5 and the tile 12 which can be removed by separating from the suction cup 3.

FIG. 3 shows another embodiment of the present invention. In this example, the passage opening / closing member comprises a rotary valve 51, and an assembled perspective view of the rotary valve 51 is shown in FIG. In FIG. 5, this rotary valve 51 has a plug 57 in a rotary valve processing hole 56 and is bonded with an adhesive. This rotary valve 51 is incorporated into the valve seat 13 in the body portion 1, and then the plug 58 of the valve seat 13 is inserted into the opening of the valve seat 13 and adhered with an adhesive.

When the rotary valve 51 is used, when the lever 54 is pushed downward, the ventilation pipe 53 and the ventilation pipe 41 in the rotary valve 51 communicate with each other, and at the same time, the air in the suction cup is removed. Since it is excluded, the lever 54 is then raised upward so that the ventilation pipe 53 in the rotary valve 51 blocks the communication with the ventilation pipe 41 from the outside. Thereby, the air inside is deaerated and the tile 12 is sucked. After taking out the tile 12, when the lever 54 is pushed down again, the ventilation pipe 53 in the rotary valve 51 and the ventilation pipe 41 communicate with each other to release the airtightness and the air flows in, and the tile 12 Moves away from the suction cup 3.

In this relationship, the ventilation pipe 53 inside the rotary valve 51 communicates with the ventilation pipe 41 to the outside with the lever 54 of the rotary valve 51 raised, and the lever 54 is pushed downward. Then, the communication between the ventilation pipe 53 and the ventilation pipe 41 in the rotary valve 51 may be released.

FIG. 4 shows still another embodiment of the present invention. In this example, the passage opening / closing member comprises a piston type valve 52, and the valve 52 has a head 55 and a ventilation pipe 53 inside the valve 52. Is installed in parallel to the axis, and when this head 55 is pushed to the left and right, the ventilation pipe 41 of the body and the ventilation pipe of the valve match, venting to the outside, and where it does not match, the ventilation is cut off. To be done. Specifically, there are a case where the opening of the ventilation pipe 53 provided in the valve 52 is provided at a position shorter than the position of the ventilation pipe 41 and a case where the opening is provided at a position longer than the position of the ventilation pipe 41. Is different.

When the piston type valve 52 is used as the passage opening / closing member, the method for using the piston type valve 52 is to push the head 55 of the valve 52 (pull the other end) to allow the ventilation pipe 53 provided in the valve 52 to pass. Since it communicates with the trachea 41, when the handle is pushed downward in this state, the air in the suction cup flows out, and the tile 12 and the suction cup 3 come into close contact with each other. Here, by pulling the head portion 55 (pushing the other end), the ventilation pipe 53 and the ventilation pipe 41 provided in the valve 52 are cut off, and the tile 12 can be taken out. Then, after the tile 12 is taken out, the ventilation pipe 53 provided in the valve 52 communicates with the ventilation pipe 41 by pushing the head portion 55 so that the tile 12 can be peeled off.

This relationship is established by pulling the head 55 of the valve 52 so that the ventilation pipe 53 provided in the valve 52 communicates with the ventilation pipe 41 and by pushing the head 55 of the valve 52. The ventilation pipe 53 provided in the valve 52 may be disconnected from the ventilation pipe 41.
