Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction cup and a fitting for achieving reliable suction.

[0002]

2. Description of the Related Art Since the past, a suction cup has been widely used as a medium for locking and holding a predetermined article, especially on a vertical wall surface of a house.

As is well known, the suction cup is made of a relatively soft synthetic resin and has a conical cylindrical shape similar to a disk. The suction cup is crushed while being brought into contact with the wall surface to bring the inside into a state close to a vacuum and to the outside. It is adsorbed by utilizing the pressure difference.

However, since the conventional suction cup of this kind is formed of a relatively soft synthetic resin, it tends to be deformed by a load due to its weight when an object is hooked, and the deformation of the suction cup is reduced. As a result, air was often introduced into the interior, the vacuum state was released, and it was often seen that it peeled off from the wall surface, which was not very practical.

In view of such drawbacks, for example, Japanese Utility Model Publication No. 3-44041 and Japanese Utility Model Publication No. 61-16141.
A device as seen in Japanese Patent No. 3 has been proposed.

In these prior arts, a connecting member is erected at the center of the suction cup, and a dome-shaped pressing member is arranged so that the connecting member penetrates through. The lower end of the pressing member is the peripheral end portion of the sucker. It can come into contact with the upper surface.

Further, the connecting member and the pressing member are screwed together or assembled by means of a lever body. When the suction cup is brought into contact with the wall surface or the like, the screwing operation or the leverage operation is carried out, and the central portion of the suction cup is held. And the peripheral edge of the suction cup is pressed by the peripheral edge of the pressing material.

As a result, the inside of the suction cup is in a state close to vacuum and is sucked onto the wall surface, and the peripheral edge of the suction cup is pressed by the peripheral edge of the pressing material, so that the vacuum state is maintained and the suction state is maintained. It will be maintained.

[0009]

However, since the suction cup serves as a medium for suspending and holding a predetermined object, it must have a certain degree of strength, but on the other hand, as described above. In order to create a vacuum inside, it must be deformable to some extent.

In order to give strength to the suction cup, it is sufficient that the hardness of the synthetic resin as the molding material is high, but in order to be deformable, it must be low in hardness, that is, soft.

Therefore, in the conventional suction cup of this type, the molding material thereof has a relatively high hardness, but as a result, the lower surface of the suction cup and the wall surface are difficult to fit, and the mutual close contact is not achieved. Air often enters the suction cup through the gap, the vacuum state is released, the suction is weakened, and the suction cup is often peeled off.

In particular, when the wall surface to be sucked is a rough surface such as a satin finish, there is a problem that mutual adhesion between the lower surface of the suction cup and the wall surface is poor.

The present invention was developed to solve the drawbacks, inconveniences, and dissatisfaction points of the above-mentioned prior art, and it is a technical subject to make the adhesion to the wall surface excellent while being excellent in strength. The purpose is to make it capable of withstanding a weight load and having an excellent adsorption force.

[0014]

In order to solve the above-mentioned problems, the present invention has a body having a conical cylindrical shape close to a disk, a connecting member standing upright at the center of the upper surface, and molded with a relatively hard synthetic resin. The adhesive layer is formed of a relatively soft synthetic resin and integrally formed on the lower surface of the main body in a laminated manner.

In this case, the adhesive layer may be integrally formed in a ring shape only on the peripheral end portion of the lower surface of the main body.

Further, utilizing the suction cup having such a structure,
The cover body is composed of a holding cylinder whose lower end can come into contact with the peripheral edge of the upper surface of the main body, and an action plate which is integrally located at the center of the upper end of the holding cylinder, and through which the connecting material of the main body is attached by through-fitting. A lever body having a supported portion as a fulcrum and a portion that can come into contact with the upper surface of the working plate as a working point is arranged to raise the central portion of the suction cup and relatively lower the cover body.

Alternatively, in this case, the connecting member may have a threaded rod structure, and a nut capable of contacting the upper surface of the working plate may be screwed into the connecting member.

[0018]

As a result of the construction described above, since the body of the suction cup is made of a relatively hard synthetic resin, it has a high strength and does not deform even if a weight load is applied.

Further, since the adhesion layer integrally provided on the lower surface of the body of the suction cup is made of a relatively soft synthetic resin, mutual adhesion does not occur even if the wall surface to be adsorbed is a rough surface such as a matte surface. Will definitely be achieved.

When the inside of the suction cup is in a vacuum state, the central portion is pulled up, and only the peripheral end portion comes into contact with the wall surface. Therefore, the adhesion layer may be arranged only on the contact surface with the wall surface which is the adsorption target surface. Therefore, the adhesive layer may be integrally provided in a ring shape only on the peripheral end portion of the lower surface of the main body.

Specifically, as a mounting tool that serves as a medium for suspending an object, the sucker is used to dispose the lever body on the cover body having the holding cylinder and the action plate, and to pivotally support the connecting member. By leveraging the part to be supported as a fulcrum, raising the central part of the suction cup, lowering the cover relatively, making the inside a vacuum state and pressing the peripheral edge, the adhesion between the adhesion layer and the wall surface Maintained.

The operation of raising the central portion of the suction cup and lowering the cover body relatively is such that the connecting member has a threaded rod structure, and the connecting member is screwed with a nut capable of contacting the upper surface of the working plate. But it can be achieved.

[0023]

EXAMPLE A suction cup 1 comprises a body 2 made of a relatively hard synthetic resin and an adhesion layer 8 made of a relatively soft synthetic resin.

The body 2 is required to have such a hardness that it is not easily deformed when a heavy load is applied, but can be slightly deformed during the adsorption operation. For example, vinyl chloride resin is adopted, and its hardness is , Hardness JIS-K63
Around 90 points in the 01A standard is desirable.

On the other hand, the adhesion layer 8 is soft enough to ensure mutual adhesion even if the surface to be adsorbed is a rough surface such as a matte surface. A resin of a system is adopted, and its hardness is preferably around 30 to 40 points according to JIS-K6301A standard of hardness.

The main body 2 has a configuration in which a flange portion 4 is provided upright around the periphery of a conical tubular portion 3 having a conical tubular shape close to a disk, and a connecting member 5 is provided upright at the center of the upper surface.
A shaft hole 6 is formed in the upper portion of the connecting member 5.

Further, in the embodiment of FIG. 2, the connecting recess 7 is opened from the lower end of the connecting member 5, and the adhesive layer 8 is formed by insert-molding the main body 2 as a part of the molding die. Be integrated into.

This assembly is strong, and the adhesive layer 8 covers the lower surface of the conical cylinder portion 3 and the entire flange portion 4, and the adhesive layer 8
Part of this will penetrate into the connection recess 7.

In the embodiment shown in FIG. 3, the adhesion layer 8 has a simple ring shape and is integrally provided only on the peripheral end portion of the lower surface of the conical cylindrical portion 3. This is because the bonding portion to the wall surface is only the peripheral end portion of the lower surface of the conical cylindrical portion 3, and the molding material cost is reduced.

A tongue piece 9 projects laterally from a part of the peripheral end of the conical cylinder portion 3 or the adhesive layer 8, and a fitting rod 10 is erected on the upper surface of the tongue piece 9. .

For the suction cup 1 having the above-described structure, the cover body 1
In the illustrated embodiment, reference numeral 1 is a substantially rectangular capped short tubular body in which a peripheral wall 13 is suspended from the peripheral edge of the top wall 12 in the illustrated embodiment.

The cover body 11 has a vertical posture in which the top wall 12 is parallel to the vertical wall surface in the use state. In this use state posture, the top wall 12 has a bottom from the center to the upper end. A cutout groove 14 is provided, and a deeper cutout working recess 15 is formed in the bottomed cutout groove 14 at the center of the top wall 12, and the suction cup 1 is connected to the bottom 16 of the working recess 15. A fitting hole 17 into which the material 5 is fitted is opened, and a pair of action plates 18 are formed on the bottom portions 16 on both sides of the fitting hole 17.

Next, on the inner surface of the top wall 12, a cylindrical holding tube 19 having a central portion as a center is hung, and on the inner surface of the central lower end portion of the top wall 12 in the use posture, The fitting cylinder 20 whose lower end is opened is hung down.

With the above-mentioned structure, the connecting member 5 of the suction cup 1 is inserted into the fitting hole 17 of the cover body 11 from below so that the lower end of the holding cylinder 19 contacts the upper surface of the conical cylinder portion 3 at the inner edge of the flange portion 4. In addition, the fitting rod 10 is fitted into the fitting cylinder 20 from below to be integrated.

Next, the lever body 21 has a construction in which a pair of brackets 23 are provided on both sides of the front end portion of a lever 22 which can be located in the notch groove 14 of the top wall 12 of the cover body 11. Located within 15, bracket 2
An action piece 24 is provided in a substantially semicircular shape at the lower end of the bracket 3, and a through hole 25 is opened at the center of the bracket 23.

Therefore, as described above, the suction cup 1 is assembled to the cover body 11, the brackets 23 are arranged so as to sandwich the connecting member 5 projecting from the fitting hole 17 from both sides, and the lever body 21 is attached to the suction cup 1. Assembling, the shaft hole 6 and the through hole 25 are aligned with each other, and the shaft pin 26 is passed through to integrate them.

Now, FIG. 4 shows a stand-by state before mounting on a wall surface or the like of a mounting tool 27 constructed by assembling and integrating the suction cup 1, the cover body 11 and the lever body 21. The bracket 23 of the lever body 21 is located in the working recessed portion 15, and the lever 22 pivots via the shaft pin 26 to be separated from the cutout groove 14 and project obliquely to the top wall 12.

In this state, when the adhesion layer 8 of the suction cup 1 is pressed against a predetermined wall surface or the like and the lever 22 is pushed down so as to be housed in the cutout groove 14, the bracket 23 rotates in the action recessed portion 15, The peripheral edge of the substantially semicircular action piece 24 at the lower end abuts the upper surface of the opposing action plate 15.

Then, further force is applied to force the lever 22.
Is pushed down and the upper surface of the lever 22 and the upper surface of the top wall 12 are positioned so as to be substantially flush with each other.
The shaft pin 26 portion serves as a fulcrum, the peripheral portion of the action piece 24 that abuts on the upper surface of the action plate 15 acts as an action point, and the portion that pushes down the lever 22 acts as a force point. The lever action causes the conical cylinder portion 3 of the suction cup 1 and the connecting member 5 to act. Then, a slight elastic deformation is generated, and the central portion is lifted up so that the cover body 11 is relatively lowered.

In this state, the inside of the suction cup 1 becomes almost vacuum, and the adhesion layer 8 is pressed against a predetermined wall surface to be in close contact, and the contact portion of the adhesion layer 8 to the wall surface is lowered.
The lower end of the holding cylinder 19 of No. 1 is strongly pressed from below and the close contact state is maintained (see FIG. 5).

On the contrary, to release this close contact, the lever 22
4 and the cover body 11 is lifted up against the wall surface or the like, and the state of FIG. 4 is restored.

However, since the adhesion between the adhesion layer 8 and the wall surface is strong, the vacuum state in the suction cup 1 is not released and is rather difficult to remove only by returning to the above state.

However, the fitting rod 10 of the suction cup 1 is fitted and integrated with the fitting body 20 of the cover body 11. Therefore, if the cover body 11 is lifted from the wall surface or the like when releasing the above, the fitting rod 10 is pulled up as the cover body 11 floats, and the adhesion layer 8 is also partially pulled up. A gap is created between the two, and air can enter to release the vacuum state.

It should be noted that the means for lowering the cover body 11 while pulling up the conical cylinder portion 3 and the connecting member 5 of the suction cup 1 and raising the cover body 11 relative to each other does not have to utilize the lever action as described above. Any means may be used as long as the same phenomenon occurs.

For example, the connecting member 5 has a threaded rod structure, and a nut capable of contacting the upper surface of the action plate 18 is screwed onto the connecting member 5, and the nut is tightened to connect the conical cylindrical portion 3 of the suction cup 1 to the connecting member 5. The material 5 may be lifted and raised, and the cover body 11 may be relatively lowered (not shown).

By the way, on the upper surface of the top wall 12 of the cover body 11,
A pair of locking recesses 28 are provided on both sides of the lower portion of the cover body 11 in the use posture. Therefore, in actual use,
A predetermined object is locked in the locking recess 28.

For example, FIG. 8 (a) shows a soap tray 29 mounted, and FIG. 8 (b) shows a sponge container 30,
(C) shows a state in which the locking hooks 31 are respectively mounted, and it may be in any form and may have a heavy weight load.
