Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a fastener for holding down and mooring an object, and particularly to a fastener suitable for fastening wires.

[Prior art and its problems]

Conventionally, as a method of mooring wiring etc. to pillars and walls,
Wiring, etc., were tied together with string, and the string was screwed or glued.

To fasten with screws, it is necessary to make screw holes in the pillar or wall. In addition, attachment and detachment require the attachment and detachment of screws, which is troublesome and easy to lose the screws.

If adhesive is used, it is difficult to attach and detach. Also,
On the other hand, there are few adhesives with sufficient weather resistance, and the adhesive strength decreases at high temperatures, which can lead to the straps peeling off.

[Purpose of invention]

The purpose of this invention is to use two U-shaped members with concave and convex portions on the legs, and to fit one fixed member to the other to achieve a fastening function that is easy to attach and detach, and is mechanically stable. The purpose is to eliminate the above drawbacks.

[Summary of the idea]

A stop according to an embodiment of the present invention uses a support having a U-shaped cross section, which is often used as a metal support. A member having a U-shaped cross section will be referred to as a U-shaped member.

The U-shaped post has holes along its legs.
The other member for forming the stop is also a U-shaped member, which has a cantilevered projection at the shoulder of the leg. The opening of the member having the protrusion at the leg shoulder position is inserted into the U-shaped support, and the protrusion is fitted into the hole to form a stop.

The wire to be tethered is inserted between these two U-shaped members.

When removing the wiring, the convex portion is pushed from the outside through the hole to disengage the convex portion from the hole.

[Example of idea]

FIG. 1 is a diagram showing the usage situation of an embodiment of the present invention, and FIG. 2 is a detailed diagram of the insertion member 1 shown in FIG.
FIG. 3 is a diagram showing a method for attaching and detaching the insertion member 1 to and from the support column 2.

The gutter-shaped support 2 having a U-shaped cross section is generally made of metal or plastic, and has support holes 21 provided at approximately equal intervals along its edge. The insertion member 1 is also a short U-shaped gutter-like body, and has a protrusion 12 forming a convex portion at the shoulder portion thereof. The opening of the insertion member 1 is inserted into the gutter-like portion of the support post 2, and the protrusion 12 and the support hole 21 are fitted to connect the two.

The wiring 4 is moored in two ways, as shown in FIG. One method is to compress and anchor the wiring by passing the wiring 4 through a cylindrical part formed by the support 2 and the insertion member 1. If wiring 4 is thin,
It may also be used to determine the wiring route of the wiring 4.

Another method is to fit the insertion member 1 to the support column 2 and position it, and then to anchor the wiring 4 with a strap 3 passing through the strap hole 11.

The wiring 4 can be unmoored by pressing the protrusion 12 from the outside to disengage the protrusion 12 from the post hole 21.

Details of the insertion member 1 are shown in FIG. 2, and fitting and unfitting of the insertion member 1 and the support column 2 are shown in FIG. 3.

A, B, C, and D in Fig. 2 are insert members 1, respectively.
They are a plan view, a front view, a right side view, and a bottom view. In general, the insert member 1 is preferably made of an elastic material such as metal or plastic, and has a shape particularly suitable for molding.

The insert 1 has a short leg 13, a bottom 14 and a long leg 15. Cantilever beam 17 from short leg 13
is provided in the direction of the bottom portion 14, and two protrusions 12 are provided at the tip of the cantilever beam 17. When the insertion member 1 is removed from the support column 2, the protrusion 16 is attached to the cantilever beam 17.
This is a stopper that prevents the metal from being excessively biased inward and breaking. Of course, the insertion member 1 can be made of a material with low elasticity, but the ease of attachment and detachment during repeated use is poor.

FIG. 3 shows how the insertion member 1 is attached to and removed from the support column 2. Figure A shows the insertion member 1 being inserted into the cavity 23 of the strut 2. bottom 1
4 is pushed in the direction of the arrow, and the insertion member 1 enters the cavity 23 of the support column 2, resulting in the state shown in B in the figure. In the figure B, the protrusion 12 is fitted into the post hole 21, and the insertion member 1 cannot be easily removed from the post 2. The long legs 15 facilitate this because of their length and the obtuse angle they make with the bottom 14. C in the figure shows that the insertion member 1 is inserted into the support hole 2 in order to escape from the cavity 23 of the support support 2.
1 through which the protrusion 12 is pressed in the direction of the arrow with a thin rod. Due to the above-mentioned pressing of the protrusion 12,
Since the protrusion 12 is disengaged from the post hole 21 and becomes as shown in D in the figure, the insertion member 1 can be removed from the cavity 23 by pulling the bottom part 14 in the direction of the arrow.

[Effect of idea]

As described above, according to the present invention, the following effects can be obtained.

(1) Locked members such as wiring are stably fixed through mechanical engagement, making them less susceptible to environmental changes such as temperature.

(2) Since the second member is engaged with the first member only by one of the legs and can be easily attached and detached, it is easy to insert and remove the locked member.

(3) Since the second member can be attached to the first member at any location and in any number, it is possible to use the fastener according to the location where the fastener is installed.

(4) If necessary, it is possible to attach a cord to the mounting part and moor the wiring with the cord.
