Description

  The present invention relates to a suction cup mounting structure that is fixed to a wall surface of a bathroom, a washroom, a kitchen or the like to place and store small items for daily use.

Conventionally, various mounting devices using a suction cup are known (Patent Document 1).
ACT 6-48482

The device disclosed in Patent Document 1 fixes an article support such as an accessory arrangement shelf to a wall surface by an adsorption force generated by pressing a suction cup against the wall surface.
The article support can be fixed at a desired position simply by pressing the suction cup against the wall surface, but the adsorption force to the wall surface is due to the elastic restoring force of the bowl-shaped suction cup made of an elastic member. There was a problem that the force was weak and the suction cups easily dropped from the wall surface during use.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a suction cup mounting structure that enhances the suction force of the suction cup and prevents the suction cup from dropping.

In order to achieve the above-described object, the suction cup mounting structure of the present invention includes a mounting body that can store the suction cup, a projecting opening from the center of the mounting body, a slit at the tip, and an inner annular projection. A cylindrical portion provided with a sleeve, a sleeve extending perpendicularly from the center of the suction cup and projecting from the cylindrical portion, a push button attached to the tip of the sleeve, and an interposition between the push button and the mounting body. The outer ring-shaped protrusion is provided on the outer periphery of the push button, and the outer ring-shaped protrusion is engaged with the inner ring-shaped protrusion.
In addition, an identification line is provided on the outer periphery of the push button, and the identification line protrudes from the cylindrical portion when not attracted.

The effect | action by the said problem-solving means is as follows.
Push the pushbutton with your finger until the outer annular projection jumps over the inner annular projection.
When the finger is released from the push button, the outer annular projection and the inner annular projection are locked with each other by the compressed coil spring, and the suction cup projects from the mounting body.
If the locked state of the outer annular projection and the inner annular projection is released while the suction cup in the locked state is applied to the wall surface, the suction cup is housed in the mounting body by the compressed coil spring, and at the same time, the central portion of the suction cup It comes to be peeled off from the wall surface.
Since the coil spring is always biased in the direction of peeling the center of the suction cup from the wall surface, a decompression space for generating a strong adsorption force is formed between the suction cup and the wall surface.
Further, the coil spring may be compressed and adsorbed by pressing the push button until the identification line is hidden in the cylindrical part while directly pressing the suction cup against the wall surface without bringing the suction cup into the locked state.
When the push button is pushed, the sleeve is also pushed, the central portion of the suction cup integrated with the sleeve is pushed toward the wall surface, and the air in the suction cup is pushed against the wall surface and sucked.
After being attracted, the central portion of the suction cup is peeled off from the wall surface by the biasing force of the compressed coil spring, and a decompression space that generates a strong attracting force is formed.
When the identification line protrudes from the cylindrical portion during use, the push button is pressed to compress the coil spring, and a strong adsorption force is generated again.

Since the suction cup mounting structure of the present invention is as described above, the following effects can be obtained.
<A> Since the decompression space is always formed so that the center of the suction cup is peeled off from the wall surface by the urging force of the coil spring, the suction force of the suction cup becomes extremely strong.
<B> When the suction cup is in the locked state, it is only necessary to release it, so that it can be used with peace of mind even on a wall that is easy to break, such as a glass surface.
<C> Since the identification line indicating the suction state is provided, the suction state can always be confirmed.

Embodiments according to the present invention will be described below with reference to the drawings.

FIG. 2A is a sectional view in a locked state, and FIG. 3A and 3B are external views of the suction cups. FIG. 3A is a diagram showing a non-adsorption state, and FIG. 3B is a diagram showing an adsorption state. FIG. 4 is a perspective view of a towel rack using a suction cup, and FIG. 5 is a perspective view of a towel rack using a suction cup at both ends.

<A> Overall structure (FIGS. 1, 2, and 3)
A suction cup 1 that is attracted to the wall surface W, a mounting body 2 that can accommodate the suction cup 1, a sleeve 13 that extends from the suction cup central portion 11, a cylindrical portion 21 that is provided in the mounting body 2 so that the sleeve 13 passes through, and a tip of the sleeve 13 And a coil spring 4 that acts between the push button 3 and the mounting body 2 and urges the suction cup 1 toward the mounting body 2.

<B> Suction cup (Fig. 1)
The suction cup 1 is made of, for example, an elastic material such as rubber, silicon, or soft polyvinyl chloride. In the free state (non-adsorptive state), the suction part 1 has a bowl-shaped adsorption surface 10 in which the central part 11 is slightly recessed from the peripheral part 12. It is what you have.
A sleeve 13 extends at a right angle from the central portion 11 of the suction cup 1.
The sleeve 13 has a flat flange 14 at one end, for example, and the flange 14 is embedded in the suction cup central portion 11 and is integrally coupled to the suction cup 1.
A lip 15 for peeling is connected to the peripheral edge 12 of the suction cup 1.

<C> Mounting body (Fig. 1)
The mounting body 2 includes a bowl-shaped portion 20 that houses the suction cup 1 and a cylindrical portion 21 through which the sleeve 13 passes.
A flat surface 24 is formed at the center of the bowl-shaped portion 20, and a hole 25 through which the sleeve 13 passes is opened.
The mounting body 2 is made of, for example, a metal such as aluminum, brass or copper, or a synthetic resin such as hard vinyl chloride resin or ABS resin.
A plurality of slits 22 are inserted from the distal end of the tubular portion 21 so that the distal end portion of the tubular body 21 can be expanded.
An inner annular protrusion 23 is provided on the inner end of the cylindrical portion 21.

<D> Push button (Fig. 1)
The push button 3 is attached to the tip of the sleeve 13.
The push button 3 is for compressing the coil spring 4, locking the suction cup 1, and pressing the suction cup 1 toward the wall surface W as will be described later.
An outer annular protrusion 30 is provided on the outer periphery of the push button 3, and an identification line 31 is provided further on the outer annular protrusion 30.
The outer annular protrusion 30 is engaged with the inner annular protrusion 23 and constitutes a locked state described later.
The identification line 31 is a visual indicator, and is an annular ring having a contrasting color, for example, red compared to the mounting body 2.
The identification line 31 can be displayed so as to protrude from the cylindrical portion 21 when the suction cup 1 is in the non-adsorption state (see FIG. 3A), and inside the cylindrical portion 21 when the suction cup 1 is in the adsorption state. Cannot be displayed (see FIG. 3B).

<E> Coil spring (Fig. 1)
The coil spring 4 is interposed between the push button 3 (back surface) and the mounting body 2 (flat surface 24) so as to surround the outer periphery of the sleeve 13.
The coil spring 4 is for urging the suction cup central portion 11 in the direction of peeling off the wall surface W.

<E> Action The state of FIG. 1 shows a non-adsorption state of the suction cup 1, and the suction cup 1 is urged toward the mounting body 2 by a coil spring 4 (see FIG. 1B).

(1) Locked state (Fig. 2 (A))
When the push button 3 is pushed with a finger, the sleeve 13 is pushed while compressing the coil spring 4, so that the suction cup 1 integrated with the sleeve 13 is also pushed out of the bowl-shaped portion 20 and protrudes.
When the outer annular protrusion 30 abuts on the inner annular protrusion 23, the outer annular protrusion 30 is pushed over the slot 22 while expanding the tip of the cylindrical portion 21, and the outer annular protrusion 30 jumps over the inner annular protrusion 23.
Next, when the finger is released from the push button 3, the push button 3 is urged outward (in the direction of arrow a) by the elasticity of the coil spring 4, and the outer annular protrusion 30 becomes the inner annular protrusion, as shown in FIG. The suction cup 1 is locked, and the sucker 1 is in a locked state protruding from the bowl-shaped portion 20.
In place of the inner annular protrusion 23, an inner annular recess that fits with the outer annular protrusion 30 may be used.

(2) Unlocked state (Fig. 2 (B))
Next, the suction cup 1 in the locked state is applied to the wall surface W as it is, and the hook-like portion 20 is lightly pushed, and the outer annular protrusion 30 is pulled out from the inner annular protrusion 23 in the opposite direction, and the outer annular protrusion 30 and the inner annular protrusion 23 are pulled out. Release the locked state.
Then, due to the elasticity of the compressed coil spring 4, the suction cup 1 is housed in the bowl-shaped portion 20 and the suction cup central portion 11 is peeled off from the wall surface W as shown in FIG. .
Since the coil spring 4 is always urged in the direction of peeling the suction cup central portion 11 from the wall surface W, a decompression space for generating a strong adsorption force is formed between the suction cup 1 and the wall surface W. Compared to conventional suction cups that rely on elastic restoring force, the adsorption to the wall surface is extremely strong.
When adsorbing in a locked state, the suction cup 1 is not adsorbed by pressing the wall surface W with a strong force. Therefore, it can be used safely even on a wall surface that easily breaks and is dangerous, such as a glass surface.

The coil spring 4 may be compressed by pressing the push button 3 until the identification line 31 is hidden in the cylindrical portion 21 while directly pressing the suction cup 1 against the wall surface W to be sucked without being locked. Good.
When the push button 3 is pressed, the sleeve 13 is also pushed, the suction cup central portion 11 integrated with the sleeve 13 is pushed toward the wall surface W, and the suction cup 1 is sucked by being pushed against the wall surface W while pushing out the air in the suction cup 1. To do.
After the suction, the suction cup central portion 11 is peeled off from the wall surface W by the urging force of the compressed coil spring 4, and a decompression space for generating a strong suction force is formed.

When the air leaks into the space between the suction cup 1 and the wall surface W over time, the coil spring 4 gradually protrudes the push button 3 from the tubular portion 21, and the identification line 31 is exposed.
When this is noticed, while pushing the push button 3 and compressing the coil spring 4, the air is pushed out from the space between the suction cup 1 and the wall surface W, and a strong adsorption force is generated again.
Conventionally, if used for a long time, the suction cup easily comes off from the wall surface, and the article support body falls. However, according to the present invention, the identification line 31 is removed from the cylindrical portion 21 during use. Since the push button 3 should be pushed if it protrudes, these accidents can be prevented beforehand.

  Next, examples of various devices using this suction cup will be described, but the present invention is not limited to this.

<F> Towel rack (Figs. 4 and 5)
FIG. 4 shows a towel rack 5 in which a mounting piece 26 is provided on a part of the mounting body 2 and a ring 51 is rotatably mounted via a hinge 50.
As described above, after the suction cup 1 in the locked state is applied to the wall surface W and then in the unlocked state, the suction cup 1 is housed in the mounting body 2 by the compressed coil spring 4 and at the same time the suction cup center. The part 11 is peeled off from the wall surface W and is adsorbed.
The mounting body 2 together with the push button 3 may be strongly pressed against the wall surface W, the suction cup 1 may be deformed, and the air in the suction cup 1 may be pushed out and adsorbed.
The compressed coil spring 4 pulls the suction cup central portion 11 toward the mounting body 2 and generates a strong suction force.
Thereby, the towel rack 5 can be strongly attached to the wall surface W.
From the attached state of the towel rack 5, the towel rack 5 can be easily detached from the wall surface W simply by picking up the lip 15 and introducing air into the space.

FIG. 5 shows towel racks 6 with suction cups 1 attached to both ends of the bar material.
A mounting piece 26 is provided on a part of the mounting body 2, and the suction cup 1 is mounted via a pair of hinges 60, 60.
The bar member has, for example, a double structure of an inner tube 61 and an outer tube 62 and is configured to be stretchable.
In use, the two suction cups 1 are adsorbed to the same height of the wall surface W at appropriate intervals while avoiding joints.
By combining the pair of hinges 60, 60, the suction cup 1 can be swung in two directions, a vertical plane and a horizontal plane, and can be mounted in any direction.
According to the suction cup mounting structure of the present invention, the suction cup central portion 11 is drawn to the mounting body 2, and a reduced pressure space is mechanically formed between the suction cup central portion 11 and the wall surface W, thereby providing a strong suction force to the suction cup 1. Moreover, it can be easily removed by picking up the lip 15 and destroying the decompression space, and its utility value is extremely high.
