Description

[Detailed description of the invention] This invention relates to a fastener for arranging a rod-like body to a fixed base material having a mounting hole penetrated therethrough, and more specifically, a fastener having a belt-like body around which the rod-like body is wound. Regarding.

Hitherto, various kinds of fasteners made of synthetic resin or the like having a belt-like body have been developed. For example, the fastener 101 shown in FIG.
At one end of 2, there is a stud 105 that engages with a locking part 103 and a hole 104 that is formed through the strip 102 at a predetermined interval in order to lock into the hole B that is formed through the fixed base material A.
When the rod-shaped body W is disposed, as shown in FIG.
2, the rod-shaped body W is wound around the belt-shaped body 102, and holes 104 at predetermined positions penetrated through the band-shaped body 102 are hooked to studs 105, so that the rod-shaped body W is disposed. but,
The hooking position between the hole 104 and the stud 105 is not necessarily such that the rod-shaped body W can be wound and fixed, and therefore, there is a drawback that the rod-shaped body W is allowed to move in the longitudinal direction, causing sagging. . For this reason, as shown in FIG.
A locking part 108 that engages with the hole B of the fixing base material A is provided at one end of the fixing base material A, and a locking claw 1 that inserts and locks the strip 107 near the locking part 108.
An insertion hole 109 having a diameter of 10 is provided, and a strip body 107 is provided.
Engagement pawls 111 are formed on both sides of the rod-shaped body W, and when disposing the rod-shaped body W, as shown in FIG. , the bar-shaped body W is arranged by wrapping the bar-shaped body W around the band-shaped body 107, inserting the band-shaped body 107 into the insertion hole 109, and engaging the claws 110 and 111 with each other. However, in order to securely wrap the rod-shaped body W around the band-shaped body 107, it is necessary to pull the band-shaped body 107 using a tool such as pliers to engage the claws of each other.

The present invention was devised in view of the above-mentioned conventional drawbacks, and the purpose is to provide a fastener with excellent winding force without requiring any jigs or tools. A fastener made of synthetic resin or the like for installing a rod-like body through a mounting hole, which has a locking leg that is vertically disposed on the lower surface of the belt-like body and is removable from the mounting hole.

A locking pawl 20 that engages when the long piece 18b is inserted into the hole 5 of the strip body 4 is formed on the side of the leg piece 8b from which the leg piece 19 protrudes. Further, as shown in the figure, a substantially hook-shaped holding piece 21 is formed at the lower end of the short piece 18a. Lever piece 18 formed in this way
As shown in the figure, is rotatably connected to the tip of the short piece 18a and the upper end of the rising piece 15 via a thin hinge part 22. Further, on the left side of the rising piece 15 in the drawing, a fixed leg piece 24 having a locking claw 24a at the upper end is spaced apart from the lever piece 18 by a predetermined distance 23.
are provided above so that they can be locked and fixed to each other when rotated. Note that the holding piece 21 is elastically deformable, and when the lever piece 18 is rotated, it is stored in an elastically deformed state for a distance 23, and its restoring force causes the upper end side of the fixed leg piece 24 to move in the direction of arrow C. It is formed to be pushed.

Next, the operation and effects of this embodiment configured as described above will be explained.

Now, the fastener 3 of this example is a fastener 3 that is vertically installed on the lower surface of a belt-shaped strip 4 having a plurality of engagement holes 5, and is removably elastically engaged with a mounting hole 2 that is penetrated through a steel plate body. A locking leg 6 is provided, and a locking pawl that is inserted and engaged with the engagement hole 5 of the band-shaped body 4 is provided at the upper end of the rising piece 15 provided on the upper surface near the position where the locking leg 6 is vertically provided. A substantially F-shaped lever piece 1 having 20

It is configured to be able to engage with a fixed leg piece 24 having a locking claw 24a at its tip. When installing the wire harness W using the fastener 1 formed in this way, first, the wire harness W is brought into contact with the receiving piece 17, and the band-shaped body 4 is pressed and bent in the direction of arrow A to penetrate through the band-shaped body 4. A plurality of holes 5 are arbitrarily selected according to the diameter of the wire harness W, and the lever piece 1 is
8 and engages with the locking pawl 20 to wrap the wire harness W (see FIGS. 2 and 3).

Next, when the lever piece 18 is rotated about the hinge part 22 in the direction of arrow B and pressed, the locking claw 19a of the locking leg piece 19 and the locking claw 2 of the fixed leg piece 24 are pressed.
4a are brought into sliding contact with each other and are elastically displaced, and when the locking claw 19a passes, both leg pieces 19, 24 are restored to their original positions and the mutual claws 19a, 24a are engaged (see Fig. 4). ). By rotating the lever piece 18 and engaging the locking leg piece 19 with the fixed leg piece 24 in this way, the wire harness W can be tightly wound around the band-shaped body 4. Also, one leg piece 1
When 9 and 24 are engaged, the presser piece 21 provided on the lever piece 18 is elastically accommodated in the gap 23, and its restoring force pushes the upper end side of the fixed leg piece 24 in the direction of arrow C, so that they are mutually separated. The leg pieces 19, 24 are prevented from coming off. After the wire harness W is wound in this way, the locking legs 6 are inserted into the mounting holes 2 of the steel plate body 1 and pressed, thereby being elastically locked and the wire harness W is installed. In this way, since the fastener 3 of this example is provided with the lever piece 18, the wire harness W can be tightly wound around the band-shaped body 4, so that sagging etc. when the wire harness W is arranged can be prevented. It also has many features such as no special jigs or tools required.

In addition, in the above embodiment, the wire harness W
After wrapping the strip 4 around the holder, insert the locking leg 6 into the mounting hole 2.
Although the wire harness W is exemplified as being secured through the locking leg portion, the present invention is not limited to this, and the wire harness W may be wound after being secured to the attachment hole 2 through the locking leg portion.

The present invention is a fastener made of synthetic resin, etc., for installing a rod-like body through a mounting hole penetrated through a fixed base material, and is a fastener made of a belt-like body having a plurality of engagement holes. A locking leg is provided vertically on the lower surface and is removable from the mounting hole, and the upper end of the rising piece is provided on the upper surface near the position where the locking leg is vertically installed. A fixing lock in which a substantially F-shaped lever piece having a locking pawl that is inserted into and engages with the engagement hole is connected via a thin-walled hinge portion 22, and the bent portion of the lever piece has a locking pawl. By providing a leg piece and configuring it so that it can engage with a fixed leg piece having a locking claw at the tip, which is provided above and close to the rising piece,
