Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an edge for protecting an electric wire or a cable from being damaged when an electric wire or a cable is passed through an edge of a sheet material such as a sheet metal or a printed circuit board in various electronic and electric devices. Related to protective equipment.

[0002]

2. Description of the Related Art Conventionally, when an electric wire is passed through an edge portion of a plate material such as a sheet metal or a printed circuit board, a substantially U-shaped plate having side plates 43, 43 provided on both sides of a band-shaped flat plate 42 as shown in FIG. In the cross section, a universal bush 41 formed by appropriately cutting the side plate 43 is used.

[0003]

However, since the bush 41 holds the edge portion of the plate between the side plates 43, the force for holding the edge portion is weak. In particular, when the plate thickness changes, it is not possible to cope with the change, so that an operation of fixing with an adhesive or a tape is required. For this reason, the fixing operation takes time, and the adhesive or the tape may peel off due to the change with time, and the bush 41 may come off from the edge portion.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide an edge protector which does not require a long time for fixing work and does not easily come off. And

[0005]

The present invention employs the following configuration to achieve this object.

That is, in the edge protector having side plates provided on both sides in the longitudinal direction of the band-shaped bottom, lock pieces connected by hinges at appropriate positions on both sides in the longitudinal direction of the band-shaped bottom are set up by rotating the hinge. When the boss portion is provided on one of the pair of lock pieces,
On the other hand, a hole portion to be fitted or engaged with the boss portion is provided.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment (hereinafter referred to as an embodiment) of an edge protector according to the present invention will be described with reference to the drawings.

[0008]

FIG. 1 is a perspective view showing an edge protector according to an embodiment of the present invention, FIG. 2 is a front view, and FIG.
FIG. 4 is a cross-sectional view of FIG. 2 and FIG.
6 is a perspective view showing a use state, FIGS. 6 and 7 are front views showing a use state, FIG. 6 shows a locking process, and FIG. 7 shows a lock state.

As shown in FIGS. 1 and 2, an edge protector 1 according to an embodiment of the present invention includes side plates 3, 3 supporting edge portions of a sheet metal 18 on both sides in the longitudinal direction of a band-shaped bottom 2. At the same time, lock pieces 5 and 6 connected by hinges 4 and 4 to both ends on both sides in the longitudinal direction of the band-shaped bottom 2 are provided.
The hinges 4 are provided so as to be opposed to each other when the hinges 4 are turned upright. A boss 7 is provided on one lock piece 5 of the lock pieces 5 and 6 forming a pair, and a hole 8 which is inserted into and fixed to the boss 7 of the lock piece 5 is provided on the other lock piece 6.

More specifically, an engagement protrusion 10 is provided at the tip of the boss 7 of the lock piece 5, and the engagement protrusion 1 is provided in the hole 8 of the lock piece 6.
0 is provided with an engagement projection 11 to be engaged. The direction of the engagement projections 10 and 11 is desirably a direction parallel to the longitudinal direction of the band-shaped bottom 2 so that the engagement is not easily disengaged.

A plurality of cutouts 9, 9,... Are provided at appropriate places on both side plates 3, 3.

The edge protector 1 of the embodiment of the present invention is
6, the boss 7 is passed through the hole 19 of the sheet metal 18 provided in advance as shown in FIG. 6, the hinges 4 and 4 are bent, and the hole 8 is inserted into the boss 7. Thus, the engagement protrusion 10 can be engaged with the engagement protrusion 11 to be fixed as shown in FIGS. Therefore, it can be easily attached to the sheet metal 18 without using an adhesive or a tape, and even if the thickness of the sheet metal 18 changes and backlash with the sheet metal 18 occurs between the side plates 3 and 3, it is ensured. Can be fixed.

When removing the edge protector 1 from the fixed state, the locking hole 8 is formed to
The engagement between the engagement protrusion 10 of the boss 7 and the engagement protrusion 11 of the hole 8 is released, and the engagement protrusion 10 can be removed.

FIG. 8 shows a case in which the mounting portion is mounted on a sheet metal 18 having an R shape. As described above, a plurality of cutouts 9, 9,... It can be mounted corresponding to the mounting part.

The present invention is not limited to the above embodiment. For example, in the first embodiment, the lock pieces 5,
Although 6 are provided at both ends in the longitudinal direction of the band-shaped bottom 2, they are not limited to both ends and may be provided at appropriate places. Further, the positions of the lock piece 5 and the lock piece 6 which are paired in FIG. 1 may be reversed left and right in one or two pairs. In other words, the position of the lock piece 5 and the lock piece 6 may be on either the left or right side of the band-shaped bottom 2 as long as they are paired on the left and right. Furthermore, although two pairs of lock pieces 5 and 6 are provided, the number of lock pieces 5 and 6 may be increased or decreased according to the use condition (length to be protected).
Hereinafter, an example in which the number of lock pieces 5 and 6 is increased will be described.

FIG. 9 is a side view showing the edge protector 21 of the second embodiment. The structure is almost the same as that of the first embodiment except that the number of lock pieces 5, 6 is different. A pair of lock pieces 5 and 6 are added in the middle in addition to the two ends in the longitudinal direction of No. 2 to form three pairs of lock pieces 5 and 6 in total. Therefore, the edge protector 21 can be used without detaching from the sheet metal 18 in the middle even when the length to be protected is long as shown in the side view in the use state of FIG.

The edge protector 21 is provided with a reinforcing portion 22 in the vicinity of the lock pieces 5 and 6 of the band-shaped bottom portion 2 in order to prevent breakage during work. The reinforcing portion 22 may be provided as needed.

In the first and second embodiments, the lock piece 5 and the lock piece 6 are fixed by one engagement projection 10 and one engagement projection 11 in one place. However, the number of engagement protrusions may be increased to a plurality instead of one, and a plurality of engagements may be performed. Alternatively, engagement may be performed over the entire circumference, as described later. Further, in addition to the engagement by the engagement projection, the tip of the boss 7 of the lock piece 5 is formed slightly larger than the diameter of the hole 8 of the lock piece 6, and the boss 7 is pressed into the hole 8. Alternatively, the fitting may be performed. Hereinafter, an example of engagement over the entire circumference will be described.

FIG. 11 shows an edge protector 31 of the third embodiment.
FIG. 9 is a side view of a use state showing the same as in the first embodiment except that the shapes of the engagement portions (engagement protrusions) of the lock pieces 5 and 6 are different. An umbrella-shaped engaging projection 32 is provided at the tip of the lock piece 6 over the entire circumference, a reduced-diameter portion 33 is provided in the hole 8 of the lock piece 6, the hole 8 is inserted into the boss 7, and the engaging projection 32 is reduced. It can be engaged with and fixed to the diameter portion 33.

In the first, second, and third embodiments, the engagement protrusions 10, 11, 32 and the reduced diameter portion 3 are used.
It is desirable that the insertion leading end of No. 3 has an R shape or an inclined portion formed so as to be easily inserted.

[0021]

Since the present invention is configured as described above, the following effects can be obtained.

According to the first aspect of the present invention, since the hole of the other lock piece is fitted or engaged with the boss portion of one lock piece and fixed, it can be easily attached to the edge of a sheet metal or the like. Can be attached and detached. Further, even if play occurs between the both side plates and the sheet metal, it can be securely fixed to the sheet metal.
Also unlike conventional fixing with adhesive or tape,
There is no worry that it will come off over time.
