JPH11230149A - Suction cup having gel sheet packing - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a suction cup which is simple in detachment, capable of being sucked even on a slightly curved surface, or even a slightly uneven surface by attaching a doughnut-like gel-sheet packing on a suction surface. SOLUTION: A packing 2 formed of a gel sheet is cut in a doughnut shape, and adhered on a suction surface of a suction cup 1 or to an object making use of slight adhesivity of the gel sheet, and the suction cup 1 is fitted in such a manner that the sheet is held between the suction surface and the object. The packing 2 may be adhered on the suction cup 1 at the starting time, or a recess may be provided on a part of the suction surface on which the packing 2 is adhered. When the suction cup 1 is attached, gaps formed between the suction surface and uneven parts on the surface of the object is filled with the packing 2, and no air enters inside. Thus, the suction cup 1 is not detached. The packing 2 may either circular one or an O-ring, and if the packing 2 is too thick, the movement becomes excessive due to its flexibility, and if the packing is too thin, it can not be adapted to unevenness.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Problems to be Solved by the Invention] A suction cup sticks to a smooth surface such as glass, but when the surface looks microscopically uneven, such as a television or a personal computer outside, Since there is a gap through which air passes between the suction surface and the object, the air is immediately removed. The object of the present invention is that the suction cup has 1) easy removal. 2)
It sticks even on some curved surfaces. The advantage is that it does not impair the advantage that it will not stick if it is slightly uneven.

[0002]

[Means for Solving the Problems] A gel sheet sold under the name of gel packing, frengel pad or the like is cut into a donut shape, and attached to the suction surface of a suction cup or an object using the slight adhesiveness of the gel sheet. wear. The suction cup is attached as it is between the suction surface and the target object (FIG. 1). At this time, the packing may be attached to the suction cup from the beginning, or a recess may be provided in a portion of the suction surface where the sheet is attached.
Alternatively, the sheet may be fixed at the center of the suction cup by a method as shown in FIGS. The same material as the suction cup body is used for the fixture. As shown in FIG. 4, a protrusion may be provided on the suction cup body, and the sheet may be attached by utilizing the elasticity of the gel sheet. Depending on the size of the suction cup, it is also possible to fix it at the peripheral part.

[0003]

When a suction cup is attached, the gap formed between the suction surface and the surface of the target object is filled with the gel sheet, so that no air enters the interior. Therefore, the suction cup does not come off.

[0004]

(A) A gel sheet cut into a donut shape is sold as a set with a suction cup or a product using a suction cup, and the sheet may be used only when used for an object that cannot be attached with a normal suction cup. (B) Since the gel sheet is very soft, when a force is applied to the suction cup, the suction cup moves easily and easily peels off. In order to prevent this, it is preferable that the suction body material is in direct contact with the object to some extent on the suction surface. (C) The packing can be used in a circular or O-ring shape. (D) If the packing is too thick, the movement will increase when the suction cup is attached. On the other hand, if it is too thin, it cannot cope with unevenness. Therefore, the thickness may be changed depending on the distance from the center. (E) A protrusion may be provided on the circumference of the suction surface so that the packing does not stick out. These protrusions can also be used to suppress the movement and deformation of the suction cup when a force is applied. (F) One or a plurality of small projections, holes, dents or cuts may be provided on the suction surface to prevent the packing from slipping or peeling off. Holes, depressions, cuts or protrusions may be provided at the same position on the packing side according to the size of each. The packing can be fixed by adjusting the mutual size or increasing the upper part of the protrusion. (G) A wall may be set up around the gel sheet in the shape of a tray, and used on the suction surface of the suction cup. The walls should be inclined inward.

[0005]

The present invention can be applied to an object having a slightly uneven surface.
