Description

TECHNICAL FIELD The present invention relates to a suction cup having a release function for making air leak from an airtight state to a suction cup, and a human body fixing device using the same, because a peeling force is not required when releasing the suction state. .

Conventionally, as shown in 1-A of FIG. 5, the suction cup is made of a flexible material such as rubber or resin, and in a normal state, air exists in the recess. In the state of use, by pressing the air against the flat part and pushing out the air, an air pressure of 1 atm existing on the outer surface is received and a suction force depending on the area is generated. It is well known that it is possible to support things depending on the suction force, and it is used to support homes, factories and many other facilities. Such suction cups can also be found in many patent documents. Further, in the conventional example, a suction cup with a release function is proposed as in the present invention. For example, it can be seen in Patent Document 1. This is as shown in 1-B of FIG. 5, “It is provided with an air suction hole 3 reaching the suction cup confidential part from the upper part of the support pillar 6 at the top of the suction cup, and is integrated with the insertion / extraction knob 1 in the support pillar. A suction cup with an obstructing plug 2 formed, and a suction cup with an adsorption release function that enables the desorption of opening and closing the air suction hole 3 by inserting / extracting the plug 2 at the upper part of the support column 6 ” Is. This is epoch-making as having a suction release function, eliminating the need to take up the space for removing the suction cup's protrusions, and mounting a large one with a large surface that hides the suction cup. There is a description that it was made available.
However, in this proposal as well, although the above-described improvement has been made, the plug 2 is fitted into the air suction hole 3, and in order to maintain a confidential state by pressing each other, the two are firmly pressed against each other. Therefore, a large force is required to pull out the plug 2. In addition, the support column 6 moves and the fitting position of the air suction hole 3 and the plug 2 moves during the passage of time when a heavy object is attached or removed (hanging, hanging, etc.). There is a possibility that the insertion / extraction knob 1 may be pushed up by the support column 6, and there is a concern that the air leaks and the suction state is released without being noticed. This is because a heavy object such as a luggage is hung on the support column 6 and the insertion / extraction knob 1 is gradually pushed out by the weighted impact caused by the distortion and the shaking. This is a fundamental inconvenience of the configuration in which it is inserted and removed in a straight line direction. However, the suction cups support heavy objects for a long period of time and are used with little care.
Moreover, in the proposal of patent document 1, the real aim (purpose) of the suction cup with a release function is not noticed.
The aim of the suction cup with the release function is to make it possible to create and use a large suction cup. Although the suction cup size is large, it can support heavy objects in proportion to the size. Theoretically, since it is 76 g per square cm in the atmosphere of 1 atm, it is 7.6 kg at 10 cm × 10 cm. In 20cm x 20cm, it is 30.4kg. In actual use, allow a margin and use a value smaller than the theoretical value. By the way, in spite of being able to support such a heavy object, such a large sucker is not usually made and used.
You will usually see a small sucker. This is because it is easy to press and make it stick, but it requires a large force to move it, such as removing it or adjusting its position. Therefore, the real aim of the suction cup with the release function is that the release is easy and even a large suction cup can be used.
In this case, as described above, it is difficult to simply and stably hold the suction with a simple insertion / extraction means.
