[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for manufacturing a vehicle, which comprises, for example, a predetermined bracket provided on a body of an automobile,
The present invention relates to a lock device for holding two members, a protector in which a wire harness is accommodated, and a protector in a mounted state.

[0002]

2. Description of the Related Art FIG. 5 shows an example of a conventional lock device. In this drawing, an engaging claw 58 is integrally formed on an outer wall portion of the protector 10 as one member, and an engaging hole for receiving the engaging claw 58 is formed on a bracket 30 for mounting the protector as the other member. 34 are formed. The protector 10 is provided with bracket receiving portions 26 for receiving the bracket 30 on both sides of the engaging claw 58.

[0003] Both bracket receiving portions 2 of the protector 10
When the bracket 30 is relatively inserted into the position 6, the bracket 30 passes through the engaging claw 58 while pushing down the elasticity of the wall of the protector 10. As a result, the engaging claw 58 is located in the engaging hole 34 of the bracket 30, and the two members of the protector 10 and the bracket 30 are held in a locked state.

[0004]

In the apparatus shown in FIG. 5, the engagement force between the engagement claw 58 and the engagement hole 34 after the lock between the protector 10 and the bracket 30 is large,
Although the locked state is stabilized, it is very difficult to release these engagements. In other words, in order to release the lock, insert a tool such as a flathead screwdriver between the protector 10 and the bracket 30, and push down the engaging claw 58 with the tip of the tool to release the engagement with the engaging hole 34. However, the tip of the tool cannot be hooked on the engaging claw 58, and the engaging claw 58 is often unnecessarily damaged. Therefore, there is a problem that workability during maintenance is poor and that the protector 10 cannot be used repeatedly.

[0005] The technical problem of the present invention may optionally can unlock the two members, improves the workability during maintenance of the two members when the lock release assembly

It is an object of the present invention to provide a lock device capable of easily releasing a lock .

[0006]

In order to solve the above-mentioned problems, the lock device according to the present invention is configured as follows. That locking portion of one member of the two members have engaging claws, locking portion of the other member has an acceptable engaging hole of the engaging claw, a predetermined set of these two members Attached
By assembling from the mounting direction, the two lock portions relatively approach each other in a direction along which the engagement claws and the engagement holes coincide with each other, and the engagement claws are moved by the elasticity of the lock portions. A lock device of a type in which the other lock portion passes while being pushed down and the engagement claw is positioned in the engagement hole thereof, whereby both lock portions are held in a locked state;

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. In the following embodiment, the lock device of the present invention is applied to a mounting portion of a protector for a wire harness.

First, FIG. 1 is a perspective view showing a lock device.
FIG. 2 shows a sectional view thereof. In these figures, a protector 10, which is one of the two members, has a lock portion 12 on a part of its outer wall.
The lock portion 12 includes an engagement claw 18 and a pair of bracket receiving portions 26 located on both sides of the engagement claw 18.

The engaging claws 18 project from the flexible portion 13 which is a part of the outer wall of the protector 10. The flexible portion 13 is elastically bent in a direction in which the engagement claw 18 is pushed down by the slits 14 formed on both sides of the engagement claw 18 and the thin portion 16 formed on the back surface as shown in FIG. Configuration. The bracket receiving portion 26 is also formed integrally with the outer wall of the protector 10,
Further, these have a shape capable of receiving the bracket 30 which is the other of the two members.

The bracket 30 is a member that is fixed to a body or other parts of an automobile and supports the protector 10. An end of the bracket 30 is connected to a lock portion 32 inserted into the bracket receiving portion 26.
It has become. The lock portion 32 has an engagement hole 34 in which the engagement claw 18 can be received.

When the lock portions 12, 32 of the protector 10 and the bracket 30 are relatively close to each other along the mutual plane, the lock portion 32 of the bracket 30 is inserted into the bracket receiving portion 26. Becomes Here, the engaging claw 18 has a tapered surface 20 on the side facing the bracket 30 when the lock portions 12 and 32 are relatively approached, and an engaging surface 22 on the opposite side.

Further, the engaging surface 22 of the engaging claw 18 has
The unlocking concave portion 24 is formed by cutting out a substantially central portion thereof with a constant width. The width of the recess 24 is
The dimensions are set so that the tip of a tool T such as a flathead screwdriver described later can be inserted. Also, this recess 24
It is desirable to be located at the center of the engagement surface 22, but it may be slightly offset from the center.

The protector 10 and the bracket 30
2A, the lock portion 32 of the bracket 30 is inserted toward the bracket receiving portion 26 of the protector 10 as shown in FIG. As a result, the end of the bracket 30 moves along the tapered surface 20 of the engaging claw 18, and the engaging claw 18 is pushed down by the bending of the flexible portion 13.

When the lock portion 32 of the bracket 30 is completely inserted into the bracket receiving portion 26 as shown in FIGS.
The engaging claw 18 is located on the engaging surface 2 of the engaging claw 18.
2 engages with the edge of the engagement hole 34. Thereby, the protector 10 and the bracket 30 are held in the locked state.

At the time of maintenance, etc., the protector 1
In order to release the lock between the bracket 0 and the bracket 30 , FIG.
As shown in (A), a tool T is inserted from the gap between the lock portions 12 and 32 toward the engagement surface 22 of the engagement claw 18.
At this time, the tip of the tool T is
Located in. Thus, when the tool T is operated in the direction of the arrow as shown in FIG. 4B, the flexible portion 13 is effectively bent in the direction in which the engaging claw 18 is pushed down. As a result, the engagement between the engagement claw 18 and the engagement hole 34 is released, and the protector 1
The lock between the 0 and the bracket 30 is easily released.

In the above embodiment, the protector 10 and the bracket 3 are used as two members which need to be locked and unlocked.
Although 0 has been described as an example, it is of course possible to apply the lock device of this embodiment to two members, for example, a main body and a lid of a wire harness protector.

[0018]

As described above, according to the present invention, the lock between the two members can be easily released as required, the workability at the time of maintenance is improved, and at the time of releasing the lock, the work is performed.
Even in places where business space is scarce,
Using the space in the mounting direction of the two parts
The tool can be inserted into the gap between the
