Description

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

Conventionally, various mounting devices using a suction cup are known (Patent Document 1, Patent Document 2).
ACT 6-48482 JP-A-11-290585

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 invention shown in Patent Document 2 uses a compressive force of a coil spring to pull a suction cup so as to generate a large adsorbing force. However, since the pressing button is small, the coil spring is compressed, A large force was required to press the suction cup, and the adsorption operation was difficult to perform.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a suction cup structure that enhances the suction force of the suction cup and facilitates the suction operation.

In order to achieve the above object, the suction cup structure of the present invention comprises a dish-shaped suction cup, a sleeve extending at a right angle from a central portion of the suction cup, a push button attached to the tip of the sleeve, and the suction cup. And a coil spring interposed between the push button and the mounting body. The outer diameter of the push button is slightly smaller than the outer diameter of the suction cup. It is characterized by being formed small.
In addition, an identification line is provided on the outer periphery of the push button, and the identification line protrudes from the mounting body when not attracted.

The effect | action by the said problem-solving means is as follows.
While pressing the suction cup against the wall, press the push button to compress the coil spring until the identification line is hidden in the mounting body.
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 urging force of the compressed coil spring, and a decompression space that generates a strong adsorption force is formed between the suction cup and the wall surface. It will be.
Since the coil spring is always biased in the direction of peeling the center of the suction cup from the wall surface, the decompression space remains formed.
Since the push button is formed slightly smaller than the outer diameter of the suction cup, the push button is large and can be pushed with a slight force, so that the suction operation is easy.
When the identification line protrudes from the mounting body during use, the push button is pressed to compress the coil spring and generate a strong suction force 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> Since the push button is formed to be slightly smaller than the outer diameter of the suction cup, the push button is large and can be pushed with a slight force, and the suction operation is easy.
<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.

<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, an opening 22 provided in the mounting body 2 so that the sleeve 13 passes through, and a tip of the sleeve 13 The attached push button 3 includes a coil spring 4 that acts between the push button 3 and the attachment main body 2 and biases the suction cup 1 toward the attachment main body 2.

<B> Suction cup (Figs. 1 and 2)
The suction cup 1 is made of, for example, an elastic material such as rubber, silicon, soft polyvinyl chloride, and the like. 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 (Figs. 1 and 2)
The mounting body 2 includes a bowl-shaped portion 20 that houses the suction cup 1 and an opening 22 through which the sleeve 13 passes.
A flat surface 21 is formed at the center of the bowl-shaped portion 20, and an opening 22 is provided there.
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 mounting piece 23 is provided on a part of the outer peripheral surface of the mounting body 2.
The attachment piece 23 is for connecting a towel rack or the like, and has a hole 24 so that, for example, a hinge can be attached.

<D> Push button (Fig. 1, Fig. 2, Fig. 3)
The push button 3 is attached to the tip of the sleeve 13.
The push button 3 is for compressing the coil spring 4 and pressing the suction cup 1 toward the wall surface W as will be described later.
The outer diameter of the push button 3 is formed to be, for example, 70 to 90% of the outer diameter of the suction cup 1 so as to be slightly smaller than the outer diameter of the suction cup 1 (outer diameter of the peripheral edge portion 12).
An identification line 30 is provided on the outer periphery of the push button 3.
The identification line 30 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 30 can be projected and displayed from the mounting body 2 when the suction cup 1 is in the non-adsorbing state (see FIG. 3A), and hidden in the mounting body 2 when the suction cup 1 is in the suctioning state. Cannot be displayed (see FIG. 3B).

<E> Coil spring (Fig. 2)
The coil spring 4 is interposed between the push button 3 (back surface 31) and the mounting body 2 (flat surface 21) 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. 2A 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.
While pressing the suction cup 1 against the wall surface W to be sucked, the push button 3 is pressed to compress the coil spring 4 until the identification line 30 is hidden in the mounting body 2.
When the push button 3 is pushed in the direction of the arrow a, 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 pushed against the wall surface W while pushing out the air in the suction cup 1. The suction cup 1 is adsorbed (see FIG. 2B).
Since the push button 3 is not so small as compared with the suction cup 1, that is, since the push button 3 is formed large, the coil spring 4 can be compressed with a slight force and the suction cup 1 can be pressed.
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 that generates a strong suction force between the suction cup 1 and the wall surface W. Will be formed.
Since the coil spring 4 is always urged in the direction of peeling the suction cup central portion 11 from the wall surface W, this reduced pressure space remains formed, and the suction to the wall surface is more than that of a conventional suction cup that relies on elastic restoring force. Become very strong.

When 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 mounting body 2, and the identification line 30 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 30 protrudes from the mounting body 2 during use. Then, since the push button 3 should be pushed, these accidents can be prevented in advance.

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

<F> Towel rack (Figure 4)
FIG. 4 shows a towel rack 5 in which a ring 51 is rotatably attached to a mounting piece 23 of the mounting body 2 via a hinge 50.
The mounting body 2 is pushed toward the wall surface W together with the push button 3 to deform the suction cup 1 to push out the air in the suction cup 1 for adsorption.
Since the push button 3 is formed large, it can be pushed with a slight force and the suction operation is easy.
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.

<G> Accessories holder (Fig. 5)
FIG. 5 shows an example of the accessory receptacle 6 using the suction cup 1 of the present invention.
A substantially elliptical saucer 60 is connected to a part of the mounting member 2.
An appropriate number of draining grooves 61 are provided in the tray 60.
Small items such as soap and scourer can be placed on the saucer 60 and can be easily mounted on the wall surface W simply by pressing the push button 3 in the same manner as the towel rack 5 described above.
According to the suction cup structure of the present invention, since the push button 3 is formed large, the coil spring 4 can be compressed with a slight force, the suction cup 1 can be deformed, and the suction operation is easy.
Further, the suction cup central portion 11 is drawn to the mounting body 2, and a decompression space is mechanically formed between the suction cup central portion 11 and the wall surface W to generate a strong suction force on the suction cup 1, and the lip 15 It can be removed easily by picking up and destroying the decompression space, and its utility value is extremely high.
