Japanese Patent Laid-Open No. 10-57220 Noboru 2568453 No. JP 2005-304642 A

  As described above, Document 1 has a hanger attached directly to a flexible suction cup, so that when the article is suspended, the smooth surface and the article come into contact with each other to stain the smooth surface or the article. It can be attached to non-smooth pillars and walls, with the disadvantage that the air flow between them is poor and the laundry does not dry quickly, the flexible sucker is deformed by the load weight and the negative pressure is released and it is easy to peel off There were no drawbacks.

Since the suction sucker of Document 2 has a hook attached directly to the sucker body, when the article is suspended, the smooth surface and the article come into contact with each other to contaminate the smooth surface or the article, or the suspended article and the smooth surface There was a defect that the air flow between them was poor and the laundry did not dry quickly and that it could not be attached to a non-smooth pillar or wall.
Furthermore, the suction sucker required a procedure for raising the hook body and adsorbing it on a smooth surface.

Although Document 3 can hang an article away from the wall surface, it has the disadvantages that it cannot be attached to a non-smooth column or wall surface, and that it uses two suction cups and two support arms, so there are many parts. It was.
Furthermore, the suction sucker required a procedure for raising the arm and adsorbing it on a smooth surface.

In order to solve the above-mentioned problem, the present invention is an inverted dish-type double structure suction cup having a convex center part composed of an outer hard cover and an inner flexible suction cup, and the rear surface of the flexible suction cup. A connecting rod protrudes from the center, and a hole through which the connecting rod penetrates is provided at the center of the hard cover , and the pressure dispersion is made of a hard synthetic resin inserted into the connecting rod. The connecting rod of the flexible sucker is passed through the hole of the hard cover through a ring and overlapped, and the arm is connected to the hole provided at the tip of the connecting rod so that it can be tilted up and down. Yes.

Further, when the arm is positioned in a direction to stand against the hard cover in the previous period and the flexible sucker is not adsorbed to a smooth surface , the arm is positioned outside the peripheral edge of the flexible sucker and the flexible sucker is smoothed. An L-shaped convex piece may be provided at the lower peripheral edge of the hard cover when viewed from a cross section having a height that is flush with the suction surface of the flexible suction cup when it is attracted to a flat surface .

Then, when the suction cup is pressed against the smooth surface to be adsorbed and the arm is raised, the bottom of the arm base comes into contact with a convex piece having a height at which the upper portion of the arm maintains an acute angle with respect to the smooth surface. You may provide in the center part upper surface of the said hard cover.

  Further, a deficient portion may be provided at the upper peripheral edge of the hard cover, and a hanging piece having a through hole may be provided at one end portion of the upper surface of the flexible suction cup corresponding to the deficient portion.

  The pressing dispersion ring may be integrally formed with a connecting rod protruding from the flexible suction cup.

The hard cover is a hemispherical inverted dish type made of a hard synthetic resin, and a hole is provided in the center, and the flexible sucker is a hemispherical inverted dish type made of a soft synthetic resin as a back surface. A connecting rod made of hard synthetic resin is projected in the center.
A pressing dispersion ring made of a hard synthetic resin is passed through the connection rod, and the pressure distribution ring is between the hard cover and the flexible sucker and contacts each other, and the connection hole of the connection rod The tip including the protrusion protrudes from the hole of the hard cover.
The material of the hard cover that requires strength may be a non-ferrous metal such as metal or aluminum.

Then, the arm made of a hard synthetic resin connected by a connecting pin made of a hard synthetic resin as a material may be a straight bar shape or a T-shape, and may be designed in a curved shape.
Furthermore, it is possible to prevent slippage of the hook hung on the arm by providing a recess for preventing slipping on the upper part of the arm, and because the arm requires strength, a crosspiece may be put on the side, Moreover, you may use nonferrous metals, such as a metal and aluminum.

In addition, the range of the length of the L-shaped convex piece provided at the lower peripheral edge of the hard cover may be 2/3 to 1/12 of the peripheral edge of the hard cover.
The double structure suction cup of the present invention distributes the load weight when the article is suspended on the arm to the L-shaped convex piece through the flexible suction cup and the hard cover, but the length of the L-shaped convex piece. There is no significant change in the distribution of load weight when the value exceeds 2/3 and below 2/3.
Further, when the length of the L-shaped convex piece is 1/12 or less, a fluttering phenomenon occurs in the arm connected to the double structure suction cup of the present invention.

When the arm is erected, the arm base bottom comes into contact with the hard cover due to load weight.
Further, a protrusion may be provided on the bottom of the arm base instead of the convex piece made of a hard synthetic resin provided on the upper surface of the hard cover.
When the smooth surface is inclined toward the front like an inner window of an automobile, a convex piece having a height such that the arm has an acute angle upward from the horizontal may be provided.

And the range of the defect | deletion part provided in the peripheral edge upper part of the said hard cover is good in order to aim at the stability of the said suction cup about 1 / 2-1 / 6 of a periphery.
If the deficient portion is ½ or more, it causes a flicker phenomenon of the double structure suction cup of the present invention.
Moreover, when the deficient portion is 1/6 or less, it is difficult to secure a space for attaching a hanging piece having a through hole at one end of the upper surface of the flexible suction cup.

  The pressure dispersion ring is made of a doughnut-like hard synthetic resin, penetrates through a connecting rod protruding from the inner flexible sucker, adheres to the flexible sucker, and has an outer hard cover. Since they are in contact with each other, when the hard cover is pressed, the pressing dispersion ring causes the flexible sucker to be pressed, and the flexible sucker is pressed against the wall surface.

As described above, the double-structured suction cup of the present invention has a connecting rod at the center of the back surface of the inverted dish-type flexible suction cup in which the central part of the outer hard cover and the inner flexible suction cup is convex. The hard cover is provided with a hole through which the connecting rod penetrates and can protrude through the central portion of the hard cover, and the hard cover is interposed through a pressure dispersion ring made of a hard synthetic resin inserted into the connecting rod. Since the connecting hole of the flexible sucker is passed through the hole and the pressure dispersion ring is in contact with the hard cover and the flexible sucker, the hard cover is pushed against a smooth surface. Then, the pressure dispersion ring inserted into the connecting rod is pressed to evenly press the flexible sucker against the smooth surface.
As a result, a negative pressure is generated in the flexible suction cup and is effectively adsorbed on a smooth surface.
This is a modification of the procedure in which the suction sucker described in Document 2 or 3 raises the hook body or arm and adsorbs it to a simple procedure.

  Further, since the arm is connected to the hole provided in the tip portion of the connecting rod by using a connecting pin so that the arm can be tilted up and down, when the arm is raised and used, the hook is provided on the arm. Can be hung away from the smooth surface, so that the drawbacks described in Document 1 or 2 can be solved.

When the arm is located in a direction to stand up against the hard cover and the flexible sucker is not adsorbed to a smooth surface , the arm is located outside the peripheral edge of the flexible sucker, and the flexible sucker is smoothed. when adsorbed with such surfaces, by moving to Ru provided an L-shaped protruding piece as viewed from the cross-section having a height which becomes the suction surface flush with the flexible suction cup on the periphery lower portion of the hard cover, Since the arm and the hard cover are in contact with each other when the article is suspended from the arm, the load weight applied to the arm can be distributed to the flexible sucker and the hard cover. Since the double structure suction cup of the invention can be prevented from being fluttered, the disadvantage described in Document 1 is eliminated.

Further, when the suction cup is pressed against a smooth surface to be sucked and the arm is erected, the arm base bottom comes into contact with a convex piece having a height at which the upper portion of the arm maintains an acute angle with respect to the smooth surface. By providing the upper surface of the central portion of the hard cover, the flexible sucker is pulled outward when the article is hung on the arm hook or the like, and the arm is lowered from the horizontal by the weight of the article. This double structure sucker and one arm can prevent this, so the drawback described in Document 3 is eliminated.

  When a deficient part is provided in the upper peripheral edge of the hard cover, a hanging piece is provided at one end of the upper surface of the flexible suction cup corresponding to the deficient part, and when the hanging piece is pulled forward, the flexible piece The suction cup is deformed and the negative pressure state is released, so that the flexible suction cup is easy to peel off, and when the hanging piece has a through hole, the double structure sucker of the present invention is passed through the through hole with a nail or the like. Since it is now possible to hang small items by attaching it to a non-smooth place such as a pillar, the disadvantages described in Documents 1 to 3 are eliminated.

  The double structure suction cup of the present invention is a smooth surface such as the mirror or window glass because the front of the mirror or window glass in the room is often a place where air conditioning air passes in a hotel during travel or business trip. It is ideal for adsorbing the product of the present invention to be used as laundry washing, and is convenient and smooth to suspend laundry and articles by adsorbing the product of the present invention to the window glass while the vehicle is moving.
