Description

[Detailed explanation of the invention] [Industrial application field] This invention is suitable for wiring and
This invention relates to an edge protector that covers the peripheral edge of a through hole for piping.

[Conventional technology]

Examples of conventional edge protectors of this type include those shown in FIGS. 1 to 3 (see Japanese Utility Model Application Publication No. 56-91488).

This edge protector 1 is constructed by providing a plurality of attachment parts 3 on the outer surface of a cylindrical body part 2 which is inserted into a through hole B of a panel A. The attachment part 3 is composed of a collar 4 protruding from the upper edge, and a plurality of locking claws 5 facing the collar 4 and protruding from the lower edge. 4 and 5, it is attached to the body through-hole B by sandwiching the periphery of the through-hole B, as shown in FIG.

[Problem that the invention attempts to solve]

However, in the case of such a conventional edge protector 1, the outer diameter of the cylindrical body 2 is preformed to a size that matches the size of the through hole B to which it is attached. Each time the cylindrical body 2 changes, the cylindrical body 2 must have an outer diameter that matches the change, and therefore one type of edge protector cannot be used in common for various types of through holes.

In addition, since the edge protector 1 is attached to the through hole B by applying the sloped part of the locking pawl 5 to the edge of the through hole B and pushing it in, the overhang of the locking pawl 5 is 6 in order to facilitate the installation. is formed small. For this reason, problems such as a gap being created between the edge protector 1 and the periphery of the panel, causing the edge protector 1 to fall off due to vehicle vibrations, etc., and causing a rattling sound of the edge protector 1, have occurred.

This invention was made in order to solve these conventional problems, and the object is to provide an edge protector that can be used for through holes of various sizes and that can be attached closely to the through holes. With the goal.

[Means for solving problems]

The edge protector according to this invention includes a band part, a buckle with a fastening claw provided at the base end of the band part, an engaging protrusion that engages with the fastening claw provided inside the insertion end of the band part, and a buckle with a fastening claw provided at the base end of the band part. The strap is made up of a plurality of attachment parts for attaching to a plurality of panel through-holes provided on the outside of the band part, and the attachment part is made up of protrusions and locking claws formed side by side in the width direction of the band part.

[Effect]

The edge protector can be made to have an arbitrary diameter by inserting the insertion end into the buckle and engaging the retaining claw with the engagement protrusion. Therefore, one type of edge protector can be used in common for through holes having different diameters. Further, the edge protector can be attached tightly to the through hole without creating a gap or falling off.

〔Example〕

Examples of this invention will be described below with reference to FIGS. 4 to 8.

First, to explain the structure, 11 is an edge protector, 13 is a band part, 12 is a box-shaped buckle that is integrally provided and protrudes from the inner surface of the proximal end 14 of the band part 13, and 15 is an insertion end 16 of the band part 13.
It is an engaging protrusion provided on the side. The buckle 12 is integrally provided with a retaining claw 12a having elasticity that engages with the engaging protrusion 15.

The engagement protrusion 15 is connected to the band 1 as shown in FIG.
A protrusion is provided on the inside of the insertion end 16 of No. 3 with a sawtooth cross section. The retaining claw 12a of the buckle 12 can freely slide in the direction of pulling out the insertion end 16 from the buckle 12 (in the direction of arrow G), but on the other hand, it cannot move in the direction of pushing in (in the direction of arrow H). It is configured to be blocked by engagement with the engagement protrusion 15. Such a non-returning engagement can be released by pinching the retaining claw 12 and pulling it up to the state shown by the chain line.

Attachment part 17 is located at the outer middle part of the band part 13.
is provided. This attachment part 17 is for holding the periphery of the through hole B of the panel A, and is composed of a projection piece 18 and a locking pawl 19 formed on the outside of the band part 13 and arranged in the width direction thereof. The number of attachment parts 17 is not limited to two, but may be increased as appropriate.

Next, the action will be explained.

By inserting and connecting the insertion end 16 to the buckle 12, an annular edge protector 11 having an outer diameter smaller than the diameter of the through hole B is formed in advance.
In this case, the outer diameter of the edge protector 11 can be adjusted as shown in FIG. You can adjust the size accordingly.

After inserting the edge protector 11 formed in this way into the through hole B, when the insertion end 16 is pulled out, the retaining claw 12a of the buckle 12 can slide on the upper surface of the engagement protrusion 15 of the insertion end 16, so that the edge protector 11 can be pulled out. The outer diameter of the protector 11 is increased so that the protector 11 fits tightly into the through hole B and does not rattle or make noise due to vibrations or the like. At the same time, the attachment part 17 completely clamps the periphery of the through hole B, and the retaining claw 12
Since the edge protector a is engaged with the engagement protrusion 15, the edge protector 11 once installed will not loosen and come off from the through hole B.

Figure 9 shows two edge protectors 11 and 1.
1 is shown. In this case, buckle 1 of one edge protector 11
2 to the insertion end 16 of the other edge protector 11.
The annular edge protector 21 may be formed by inserting and connecting them to each other. The outer diameter of the edge protector 21 assembled in this manner can be adjusted as needed, as shown in FIGS.

Of course, it goes without saying that the number of edge protectors 11 used can be further increased if necessary.

As described above, in the embodiment, at least one edge protector is connected in an annular manner so that the annular edge protector 11 of a desired size can be freely formed, so one type can be used for through holes having various diameters. edge protectors can be shared. Therefore, manufacturing costs can be reduced, parts management is easy, and it is extremely economical.
Additionally, the edge protector will no longer fall off or cause rattling noises due to vehicle vibrations.

[Effect of idea]

As explained above, according to this invention, it is possible to obtain an edge protector that can be used for through holes of various sizes and can be attached closely to the through holes.
