Abstract

PROBLEM TO BE SOLVED: To reliably hook or lock an article of heavy weight to/on a wall and the ceiling by fixing a base board by pressing curved needles pivotally fixed to the base board in the wall and the ceiling. SOLUTION: When installing a hook 6 on a wall 7 by using this fastener 1, the hook 6 is adjusted to a prescribed position of the wall 7 so that the opening part of the hook 6 becomes the upper side. Next, the respective pressing surfaces 11a, 11b of pressure plates 3a, 3b by fixing two curved needles 4a, 4b, are pressed to the periphery of shafts 8a, 8b by a finger or a hammer, and the curved needles 4a, 4b are rotated to be pressed in until the pivotally fixing recessed parts 18a, 18b and the pivotally fixing projecting parts 17a, 17b are pivotally fixed to the wall 7 through holes 9a, 9b penetrating through a base board 2. Thus, since the fastener 1 is fixed in a state where the curved needles 4a, 4b bend in the wall 7, the wall 7 and the fastener 1 can be sufficiently fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. As shown in FIG.
The pressure plate 3 a, 3 b to which two curved needles 4 a, 4 b are fixed is provided at two predetermined positions on the substrate 2 along the longitudinal direction of the rectangular substrate 2.

The substrate 2 has a rectangular shape, but may have any shape depending on the intended use, such as a circle or a triangle.

The pressure plates 3a and 3b are axially attached to the substrate 2 by shafts 8a and 8b, and a curved needle 4 is provided at a predetermined position on the pressure plates 3a and 3b.
a and 4b are fixed. The pressure plates 3a, 3b
Is the space on the opposite side of the wall about the axes 8a and 8b from 0 to 18
It is provided rotatable by 0 °. Here, the pressure plates 3a, 3
b and the substrate 2 may be pivotally connected, or
a, 3b and a hinge provided at the joint between the substrate 2 and the pressure plate 3
a, 3b may be provided rotatably.

The substrate 2, the pressure plates 3a and 3b, and the shafts 8a and 8b which can be used in the present invention include plastic, synthetic resin, and metal. Is preferred.

The curved needles 4a, 4b are fixed to the curved needle fixing surfaces 10a, 10b of the pressure plates 3a, 3b.
b has a curved shape. The same curved needle fixing surface 1
When a plurality of curved needles 4a and 4b are provided on 0a and 10b, the curved needles 4a and 4b are pressed into the wall 7 so that the curved needles 4a and 4b are pressed.
The tips of a and 4b must all be provided in the same direction and in parallel.

FIG. 1 shows one curved needle fixing surface 10a,
Although an example in which two curved needles 4a and 4b are provided in 10b is shown, the number of curved needles 4a and 4b can be appropriately increased or decreased by the load applied to the stopper 1. For example, when fixing a heavy picture as shown in FIG. 2A, three curved needles 4 are used for one curved needle fixing surface 10, and as shown in FIG.
When fixing a light weight wiring cord, one curved needle 4 is used for one curved needle fixing surface 10.

When the curved needles 4a and 4b are provided in an arc shape centered on the shafts 8a and 8b, the curved needles 4a and 4b
Since the orbits 4a and 4b move on concentric orbits with the radius of curvature R around the a and 8b, the needles 4a and 4b can be easily inserted and removed from the wall, which is preferable. In addition, curved needle 4
In order to prevent the rotation of the a and b, when the pivot concave portions 18a and 18b are provided at predetermined positions of the substrate 2 and the pivot convex portions 17a and 17b are provided at predetermined positions of the pressure plates 3a and 3b, the curved needles 4a and 4b are attached to the wall. It is press-fitted, and the pivoting recesses 18a, 18b and the pivoting projections 17a, 17
When b is pivoted, the curved needles 4a and 4b are fixed, and the stopper 1 is securely fixed to the wall 7. The radius of curvature R of the curved needles 4a and 4b and the angle θ between the tips of the curved needles 4a and 4b, the shafts 8a and 8b, and the fixing portions 12a and 12b of the pressure plates 3a and 3b and the curved needles 4a and 4b are determined by the wall material and thickness. It can be appropriately changed depending on the size and the like. The radius of curvature R is preferably 0.5 to 2.0 cm, and the angle θ is preferably 10 to 180 °.

That is, if the wall material is hard, the curved needle 4
For example, the radius of curvature R is set to 0.5 to 1.0 cm and the angle θ is set so that the curved needles 4 a and 4 b cannot be completely pressed into the wall 7 due to the resistance of the wall material at the time of press-fitting the a and b into the wall. 10
When the wall material is soft, for example, when the radius of curvature R is increased to 1.0 to 2.0 cm and the angle θ is increased to 90 to 180 °, the stopper 1 can be secured. Is preferably fixed to the wall.

In addition, compared to the conventional linear needle, the curved needle 4
a and 4b can be formed long even with a thin wall material, so that the contact area with the wall can be widened.
The friction of a and 4b is greater than that of a straight needle, and has an effect that even if a load is applied to the stopper 1 on the side opposite to the wall, the stopper 1 hardly comes off the wall.

The curved needles 4a, 4b usable in the present invention
May be iron, steel, plastic, ceramics, etc., but it is preferably tough and hard iron, steel, etc., so as not to bend or bend when pressed into a wall.

The wall to which the stopper of the present invention can be applied may be made of any material as long as the curved needles 4a and 4b can be press-fitted.
4b is easy and preferable.

An example of the case where the above-described stopper 1 of the present invention is mounted on a wall will be described below. (FIG. 1) FIG. 1 shows a hook using the stopper 1 of the present invention. As shown in FIG. 1A, the stopper 1 of the present invention includes two curved needles 4 a along a longitudinal direction of a rectangular substrate 2.
Pressure plates 3a and 3b to which the base 4b is fixed are provided at two predetermined positions on the substrate 2, and the stopper 1 has a hook 6 provided at a predetermined position on the substrate 2; Are provided at predetermined positions.

First, the hook 6 is adjusted to a predetermined position on the wall so that the opening of the hook 6 is directed upward.

Next, the pressing surfaces 11a and 11b of the pressure plates 3a and 3b are pressed by a finger or a hammer in an arbitrary order or at the same time, and the curved needles 4a and 4b are rotated to form the holes 9a.
a, 9b into the wall until the pivoting recesses 18a, 18b and pivoting projections 17a, 17b are pivoted.

When removing the hook from the wall, inserting a finger or a flathead screwdriver or the like into the notches 5a, 5b and pulling out the pressure plates 3a, 3b facilitates removal of the hook from the wall.

Further, the stopper of the present invention comprises the curved needles 4a, 4b
Locks the fastener in a bent state in the wall,
Even if a heavy load is applied to the stopper in any direction, the wall and the stopper can be sufficiently fixed, and the use application is expanded.

For example, relatively heavy paintings, flat-panel televisions, mirrors, etc. can be used for hanging on walls.

FIG. 2A shows the stopper 1 of the present invention in a picture 13.
Here is an example applied to That is, it is preferable that the stopper of the present invention is provided integrally with the frame of the painting because there is no possibility that the painting will be shifted or dropped even by shaking such as an earthquake.

Further, if the stopper 1 of the present invention is fixed to a ceiling (not shown), it is possible to suspend a lighting lamp.

Further, as shown in FIG. 2 (b), it can be used for the wiring cord fixing portion 16 having a relatively small weight. In FIG. 2B, 14 is a wiring cord, and 15 is a wiring cord support for supporting the wiring cord 14. In this case, since the weight of the wiring cord 14 is light and the quantity thereof is large, even one curved needle 4 is sufficient.
Can be supported.

[0026]

As described above, since the stopper of the present invention has a curved needle, when the needle is pressed into a wall, the stopper is fixed in a bent state in the wall. This has the effect that a heavy article can be reliably hung or locked on a wall or ceiling, and that it is excellent in versatility as a stopper.
