Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a locking device.

[0002]

[Prior art] [Problems to be solved by the device]

 For example, a locking device with a suction cup used for temporarily storing paper such as slips, memos, and posters is known. These are composed of a suction cup and a locking arm fixed to the back surface of the suction cup, and the tip of this locking arm is configured to press and contact the suction surface on the side of the suction cup where the suction cup adsorbs. It is configured such that the paper is sandwiched between the tip of the stop arm and the suction surface.

However, the conventional locking device of this type has a drawback that the paper or the like sandwiched between the tip of the locking arm and the suction surface is relatively easy to come off, and the suction cup sucked onto the suction surface is maintained. In some cases, the suction cup may come off the suction surface in a relatively short time.

The present invention proposes an excellent locking device that solves the above-mentioned drawbacks of the prior art.

[0005]

[Means for Solving the Problems]

 With a conventional locking device that has only one locking arm that presses and abuts the locking surface, when the suction cup is sucked onto the suction surface, the drag force from the suction surface causes the locking arm to move depending on the conditions such as the pressing angle. The present invention has been proposed from the viewpoint that the suction cup may be deformed non-uniformly through this, and as a result, the pressing force at the tip of the locking arm may be reduced. The present invention proposes the present invention from the perspective that the drag force may act non-uniformly even on the contact portion of the suction cup with the suction surface, so that the suction persistence force of the suction cup may be bad.

That is, in order to solve the above problems, the locking device of the present invention shares the suction cup 2 and the base end portion fixed to the center of the back surface of the suction cup 2, and extends from the base end portion. It is composed of a pair of locking arms 3a and 3b, and when the suction cup 2 is sucked onto the suction surface 4, the inner surfaces of the tips of the respective locking arms are pressed and abutted at the suction side lateral symmetry positions of the suction surface 4. did.

[0007]

[Action]

 The pair of locking arms 3a and 3b, which press and contact the inner surface of the tip at the symmetrical position on the side of the suction surface of the suction cup, do not cancel out the drag force from the suction surface to cause uneven deformation of the suction cup. It seems that the decrease of the pressing force of the stop arm is prevented as much as possible, and that the rearward force is evenly applied to the abutting portion of the suction cup front end edge and the suction surface 4, and the suction performance of the suction cup can be maintained for a long time. .

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 and 2 show an embodiment of the present invention, in which 1 denotes a locking tool. The stopper 1 is composed of a suction cup 2 and a pair of locking arms 3a and 3b.

The suction cup 2 is made of a flexible material such as synthetic resin or rubber, and in this embodiment, it is a cylindrical locking member extending rearward from the center of the rear surface of the conical plate-shaped base 2a having an opening at the front. The protrusion 2b is provided so as to project, and the fitting recessed groove 2c is provided around the base end of the peripheral surface of the locking protrusion 2b.

Since each of the locking arms 3a and 3b is made of an elastic material such as synthetic resin or metal, it extends from the center of the back surface of the suction cup 2 and the suction surface 4 attracted by the suction cup 4 The inner surface of the tip end is pressed against and abutted at laterally symmetrical positions. The lengths of the locking arms 3a and 3b are preferably substantially equal, and the contact area and contact position with the suction surface are also preferably substantially equal.

In the present embodiment, the locking tool 1 is formed by using the locking arm constituent member A in which the locking arms 3a and 3b are integrally formed of elastic synthetic resin. The circular through hole 5 formed at a predetermined position in the central portion of the locking arm constituent member A is fitted into the concave groove 2c to fix the member A to the suction cup 2.

The one locking arm 3a of the above-mentioned locking arm constituent member A has a flat plate shape that bends forward from the center of the back surface of the suction cup 2 along the outer peripheral surface of the suction cup 2 and extends downward, and also sucks the suction cup 2. The front surface of the lower end is pressed against the suction surface 4 when it is sucked onto the surface 4, and the lower end portion is folded back in a U shape to form a hanging portion 6. The other locking arm 3b has a flat plate shape extending upward while curving forward from the center of the back surface of the suction cup 2 along the outer peripheral surface of the suction cup 2, and when the suction cup 2 is attracted to the suction surface 4, the upper end The inner surface is configured to be pressed against the suction surface 4.

The locking tool 1 configured as described above is made of glass, metal, synthetic resin, or any other material capable of adsorbing the suction cup 2 by pressing the central portion of the back surface of the suction cup 2, for example, furniture or construction. It is adsorbed on the adsorption surface 4 of an object or the like. At this time, the inner surfaces of the front end portions of the respective locking arms 3a and 3b are pressed against the suction surface, and the end portion of the locked material 7 such as a notice sheet is interposed between the one locking arm 3a and the suction surface 4. Can be locked.

FIG. 3 shows another embodiment of the present invention. In this embodiment, a pair of prismatic locking arms having an L-shaped side surface from the center of the back surface of a suction cup 2 having a front end opening and having a conical plate shape. It is configured by integrally extending 3a and 3b.

[0016]

[Effect of device]

 As described above, the locking device of the present invention shares the base end portion fixed to the central portion of the back surface of the suction cup, and has a pair of locking arms extending from the base end portion. Since the front surface of the front end of each locking arm is pressed and abutted at the lateral symmetrical position, the pressing force of the locking arm does not decrease so much that the held material to be caught falls. Is less likely to occur, and the suction cup has a good suction durability, so that it can be locked for a long time as compared with a conventional locking device of this type.

Further, it is possible to easily cover not only the horizontal surface but also the vertical surface by a simple operation of pressing the suction cup so that the suction surface is adsorbed to the suction surface and the locked material is interposed between the locking portion and the suction surface. It is possible to lock the locking material.
