Description

  The present invention relates to a suction cup and a suction cup device.

There are suction cups for attaching items to indoor wall surfaces and automobile dashboards.
This type of suction cup is conventionally formed in a disc shape from rubber or the like, and one surface in the thickness direction is an adsorption surface that is adsorbed to the surface to be adsorbed, and the other surface is the back surface.
The suction cup faces the suction surface with the suction surface facing the suction surface, and the central portion is pressed toward the suction surface to bring the suction surface and the suction surface into a vacuum state. The suction cup is attracted to the attracted surface by being held by force (see Patent Document 1).
On the other hand, if the surface to be adsorbed is formed as a leather surface, a rough uneven surface, or a rough surface, the adhesion between the adsorption surface and the surface to be adsorbed cannot be maintained. A gap is formed between the suction surface and the surface to be attracted, and it is difficult to secure the adsorptivity by the suction cup.
Therefore, the applicant of the present invention is in close contact with the surface to be adsorbed even when the surface to be adsorbed is formed as a textured surface, a rough uneven surface, or a rough surface. A suction cup that can be used has been proposed. In this suction cup, the suction surface is formed of a gel layer (Japanese Patent Application No. 2006-116359).
JP 11-193811 A

By the way, the main function of the suction cup is to be attracted to the surface to be attracted, but it is also a big feature that it can be easily removed and installed in the required place as many times as possible, and it can be removed as easily as it is adsorbed. Is a factor that increases the value of the suction cup.
In particular, when using a suction cup to mount an in-vehicle electronic device such as a portable navigation device in the passenger compartment, it is recommended to remove the in-vehicle electronic device from the car when not using the in-vehicle electronic device. The suction cups are frequently attached and detached.
The suction cups with the above-mentioned suction surface made of gel have a very strong suction force, so when mounting an in-vehicle electronic device in the passenger compartment using this suction cup, it is caused by vehicle vibration or sunlight through the windshield. On the other hand, the suction cup does not fall off due to external factors such as heat, and it is easy to use. However, when removing the suction cup, there is a problem that a large force is required against the strong suction force of the suction cup.
In a conventional suction cup, in many cases, a protruding piece for removal operation extending radially outward of the suction cup is integrally formed of the same material as the suction cup at the outer edge of the suction cup, and the suction piece is covered by gripping the protruding piece. It is made to peel off from the adsorption surface.
In this case, if the suction cup exhibits a very strong suction force, the protruding piece is formed of an elastic member, so if you try to grip the protruding piece and peel the suction cup from the suction surface, When an excessive force acts on the protruding piece, the protruding piece extends, which is disadvantageous in removing the suction cup.
The present invention has been made in view of such circumstances. The purpose of the present invention is to easily and reliably remove the suction cup from the suction surface even when the suction surface is made of gel. It is to provide an advantageous suction cup and suction cup device.

(Center axis 14)
As shown in FIG. 8, the central shaft 14 is connected to the central portion of the back surface 22 of the suction cup 12 and extends in a direction away from the back surface 22. In other words, the central shaft 14 protrudes from the center of the back surface 22 of the suction cup 12 along the thickness direction of the suction cup 12 (along the central axis of the suction surface 20) away from the back surface 22.
The central shaft 14 is formed of a rigid material, for example, a metal or a hard synthetic resin, and the lower end of the central shaft 14 is embedded in the central bulging portion of the back surface 22 of the suction cup 12.

(Case 16)
As shown in FIG. 4, the case 16 includes a skirt portion 40, a cylindrical portion 42, a mounting mechanism 44, and the like, and the case 16 is formed of a rigid material such as a hard synthetic resin.
The skirt portion 40 includes a contact portion 4002 that covers the back surface 22 of the suction cup 12 and can contact the outer peripheral portion of the back surface 22 or the position of the suction surface outside the suction cup 12 in a state where the suction surface 20 is attracted to the suction surface. Have.
The gripping member 30 attached to the protruding piece 32 is located outside the contact portion 4002.
The cylinder part 42 stands up from the center of the skirt part 40, and the central shaft 14 is accommodated therein.
The mounting mechanism 44 detachably mounts the in-vehicle electronic device 2 on the case 16.
In the present embodiment, the mounting mechanism 44 is supported on the in-vehicle electronic device 2 while being supported by the wall 44A standing up from the case 16, the sphere 44B connected to the wall 44A, and the sphere 44B. It includes a mounting portion 44C that is detachably mounted.

(Displacement mechanism 18)
As shown in FIG. 4, the displacement mechanism 18 is provided between the central shaft 14 and the case 16, and the abutting portion 4002 is attached to the outer peripheral portion of the back surface 22 or the suction cup 12 in a state where the attracting surface 20 is attracted to the attracted surface. The center axis 14 is displaced in a direction away from the surface to be attracted.
In the present embodiment, the displacement mechanism 18 includes a knob 46 and a cam (not shown).
The knob 46 is rotatably arranged at the upper end of the central shaft 14, and the cam is provided on the outer periphery of the lower end of the inner peripheral portion of the knob 46.
Then, as shown in FIGS. 4 and 5, the abutting portion 4002 is brought into contact with the outer peripheral portion of the back surface 22 or the portion of the attracted surface outside the suction cup 12 with the attracting surface 20 attracted to the attracted surface, When the knob 46 is rotated, the cam rides on a cam surface (not shown) of the case 16 and displaces the central shaft 14 in a direction away from the attracted surface.
Thereby, the adsorption | suction to the to-be-adsorbed surface of the adsorption | suction surface 20 is made more reliably.
In the state where the suction surface 20 is attracted to the attracted surface, the contact portion 4002 is brought into contact with the outer peripheral portion of the back surface 22 or the location of the attracted surface outside the suction cup 12 so that the central axis 14 is separated from the attracted surface. The structure of the displacement mechanism 18 to be displaced can employ various known structures such as a toggle lever and a coil spring, and is not limited to the structure of the embodiment.

(how to use)
Next, a method for using the suction cup device 10 will be described.
When the suction cup device 10 is attached to the suction surface, the suction surface 20 of the suction cup 12 faces the suction surface, the central axis 14 is pressed against the suction surface, and the entire area of the suction surface 20 is brought into contact with the suction surface. The contact portion 4002 is brought into contact with the outer peripheral portion of the back surface 22 or the location of the attracted surface on the radially outer side of the back surface 22.
Next, the knob 46 is rotated, and the contact mechanism 4002 is brought into contact with the outer peripheral portion of the back surface 22 or the position of the suction surface on the outside of the suction cup 12 by the displacement mechanism 18 to displace the central shaft 14 in the direction away from the suction surface. .
Thereby, the suction cup 12 is attracted | sucked to a to-be-sucked surface, and the suction cup apparatus 10 is attached to a to-be-sucked surface.

When removing the suction cup device 10, the knob 46 is rotated in the direction opposite to the above, and the displacement of the central shaft 14 away from the attracted surface by the displacement mechanism 18 is released.
Then, the gripping member 30 is gripped with a fingertip, and the gripping member 30 is pulled in a direction away from the attracted surface.
As a result, the suction surface 20 gradually peels from the suction surface from the portion near the protruding piece 32 of the suction surface 20 of the suction cup 12 toward the inner periphery of the suction surface 20, and eventually the suction surface 20 completely disappears from the suction surface. The suction cup device 10 is removed from the attracted surface.

Therefore, according to the present embodiment, the sucker body gripping member 30 is attached to the suction cup body 24 so as to be gripped from a material having a smaller elastic modulus than the elastic material forming the suction cup body 24. Yes.
Therefore, even if the suction surface 20 constituted by the gel layer 26 is firmly attached to the suction surface, the suction surface 20 can be easily and reliably peeled from the suction surface by gripping and pulling the grip member 30. This is advantageous for easily and reliably removing the suction cup 12 from the attracted surface.
In particular, if a suction cup is used to mount an in-vehicle electronic device such as a portable navigation device in the vehicle interior, and therefore it is necessary to frequently remove the in-vehicle electronic device from the vehicle as a security measure, the suction cup can be easily removed. Since it can be easily performed, it is advantageous in enhancing the usability of the in-vehicle electronic device and increasing the product value.

Further, in the conventional suction cup, a protruding piece for detachment operation extending in the radially outward direction of the suction cup 12 is integrally formed on the outer edge of the suction cup body 24 with the same material as the suction cup body 24.
Therefore, when the protruding piece is gripped and the suction cup is peeled off from the attracted surface, the gel layer 26 is strongly adsorbed, so that the protruding piece extends due to excessive force acting on the protruding piece, and the attracting surface. There is a disadvantage that it is difficult to peel 20 from the attracted surface.
On the other hand, in the present embodiment, the gripping member 30 different from the suction cup 12 can be attached with a structure in which the protruding piece does not extend, such as being attached over the entire width direction of the protruding piece. There is no problem such as stretching, which is extremely advantageous in performing the removal operation of the suction cup 12 easily and reliably.
In addition, when the protruding piece and the suction cup body 24 are integrally formed using a mold, the shape and size of the protruding piece are limited, but in the present embodiment, the gripping member 30 is used as the suction cup body 24. Therefore, it is advantageous in securing the degree of design freedom and improving the design.

As shown in FIGS. 26 and 27, the suction cup 12 includes a suction cup body 50, a central shaft 52, and a spring body 54.
The suction cup body 50 is made of gel and has a disk shape in the present embodiment. One surface in the thickness direction is a concave suction surface 20 and the other surface is a convex back surface 22.
The suction surface 20 has a circular shape in plan view.
Since the gel does not have elasticity and it is difficult to maintain the shape, such a shape is maintained by a spring body 54 described later.
As such a gel, the gel similar to the gel which comprises the gel layer 26 in 1st Embodiment can be used.

The central shaft 52 projects from the center of the back surface 22 of the suction cup body 50 along the central axis of the suction surface 20 in a direction away from the back surface 22.

This is advantageous for easily and reliably performing the removal operation from the attracted surface.
In particular, if a suction cup is used to mount an in-vehicle electronic device such as a portable navigation device in the vehicle interior, and therefore it is necessary to frequently remove the in-vehicle electronic device from the vehicle as a security measure, the suction cup can be easily removed. Since it can be easily performed, it is advantageous in enhancing the usability of the in-vehicle electronic device and increasing the product value.

In addition, when a protruding piece for removal operation extending radially outward of the suction cup 12 is integrally formed on the outer edge of the suction cup body 24 with the same gel as the suction cup body 24, the suction piece is grasped by gripping the protruding piece. Since the suction by the suction cup main body 50 made of gel becomes strong when the surface is peeled from the surface to be attracted, the projecting piece is extended by an excessive force acting on the projecting piece, and the attracting surface 20 is peeled off from the surface to be attracted. There are disadvantages that make it difficult.
On the other hand, in the present embodiment, since the gripping member 30 is attached to the spring body 54, there is no problem such as extension of the protruding piece, and the removal operation of the suction cup 12 can be performed easily and reliably. It is advantageous.
