Description

[Detailed description of the invention] <Industrial application field> This invention is designed to attach a member to be attached, which is formed with a locking leg with a head that bulges in the left-right direction at the tip, to correspond to the locking leg. The present invention relates to a mounting structure for two objects to be mounted on a mounting member having a locking hole formed therein.

<Prior art> Conventionally, this type of two-object mounting structure has been
Automobile console box 1 as shown in the figure
etc.

This console box 1 is comprised of a lid part (attached member) 3 and a box part (attachment member) 5.

The rear end of the lid part 3 is rotatably connected to the rear end of the box part 5 via a hinge (not shown). Further, a locking leg portion 4 is provided on the lower surface of the front end side of the lid portion 3.
is formed to protrude perpendicularly to the lower surface of the lid portion 3.

The locking leg portion 4 has a head 4a bulged in the left-right direction at its tip.

Further, a locking leg portion 4 is provided near the front end of the box portion 5.
A locking body 2 having a locking hole 6 is disposed at a position corresponding to a. Elastic pieces 7, 7 are provided on the inner surfaces of the left and right side walls of the locking body 2, respectively, to protrude and face each other so as to narrow the left and right width of the locking hole 6.

The elastic piece 7 has a neck portion 7 connected to the inner surface of the left and right side walls.
a, and an engaging portion 7b extending downward and disposed at the tip of the neck portion 7a. The engaging portion 7b is
The substantially central portion in the vertical direction projects most inward, and forms a narrow portion smaller than the horizontal width of the head 4a of the locking leg 4 with the opposing engaging portion 7b.

When the lid part 3 is closed, the locking leg part 4 of the lid part 3 is inserted into the locking hole 6 of the box part 5. At this time, when the head portion 4a of the locking leg portion 4 passes through the narrow portion formed by the elastic pieces 7, 7, the neck portions 7a, 7a of the elastic pieces 7, 7 are deformed in a spring-elastic manner. The joining parts 7b, 7b are moved outward as shown by the two-dot chain line in FIG. Thereafter, as the diameter of the head 4a becomes smaller, the engaging portions 7 of the elastic pieces 7, 7
b, 7b move inward to return to their original state due to elastic force, and the head 4a is locked and attached by the engaging portions 7b, 7b.

<Problems to be solved by the invention> However, as described above, in order to open the lid 3 from the state where the locking leg 4 is locked to the locking hole 6 and the lid 3 is closed, the locking hole is closed. When pulling out the locking leg portion 4 from the elastic pieces 7, 7, the engaging portions 7b, 7b of the elastic pieces 7, 7
However, due to the frictional force with the locking leg 4, as the locking leg 4 is pulled upward, it tends to bend inward and obliquely upward around points P and P shown in FIG.

Therefore, compared to the insertion force for inserting the locking leg 4 into the locking hole 6, the removal force for pulling out the locking leg 4 from the locking hole 6 was higher (approximately twice).

Therefore, when the lid part 3 is opened from the closed state, a force greater than the force required to close it is required, resulting in poor operability.

This invention solves the problem described above, and the removal force that pulls out the locking leg formed on the attached member from the locking hole formed in the mounting member causes the locking leg to move into the locking hole. It is an object of the present invention to provide a mounting structure for two objects that has the same insertion force as the insertion force and can improve operability.

<Means for Solving the Problems> The two-object mounting structure according to this invention is such that a member to be attached is formed with a locking leg portion having a head that bulges in the left-right direction at the tip, and a locking leg portion In a structure to be attached to a mounting member having a locking hole formed corresponding to the locking hole, the locking hole is provided with an elastic piece inside the locking hole to narrow the horizontal width of the locking hole. It has a neck that is connected to the surface, and an engaging part that is disposed at the tip of the neck and that locks with the head of the locking leg.When the locking leg is inserted into the locking hole, the neck has a spring elasticity. A two-piece mounting structure that locks the head at the engaging portion so that the head can be pulled out by deforming, and the neck of the elastic piece is along the inner circumferential surface on the left or right side of the locking hole, and The elastic piece extends in a direction perpendicular to the insertion direction of the locking leg, and the engaging part of the elastic piece is formed to protrude inward in the left-right direction of the locking hole, so that the elastic piece is perpendicular to the insertion direction of the locking leg. The above-mentioned problem is solved by being able to swing elastically within the plane.

<Operations and effects of the invention> In the two-object mounting structure according to this invention, the neck of the elastic piece is along the left or right inner peripheral surface of the locking hole and perpendicular to the insertion direction of the locking leg. The engaging portion of the elastic piece is formed to protrude inward in the left-right direction of the locking hole, and the elastic piece swings elastically in a plane perpendicular to the insertion direction of the locking leg. It is considered possible.

Therefore, when the locking leg portion formed on the attached member is inserted into the locking hole, and when it is pulled out from the inserted state, the elastic piece remains in the engaging portion in the same way as before. External forces are applied in the insertion direction and withdrawal direction due to the frictional force generated by sliding contact with the locking leg. However, the neck of the elastic piece does not bend in the direction of these external forces, and the elastic piece elastically deforms outward in the left-right direction of the locking hole, regardless of the movement direction (insertion direction and movement direction) of the locking leg. . Therefore,
The locking leg can be pulled out with the same force as when inserting the locking leg, making the removal operation easier.

Furthermore, since the present invention has a configuration in which the neck of the elastic piece is formed in a direction perpendicular to the insertion direction of the locking leg, the elastic piece can be engaged without reducing the engagement effect with the locking leg. The dimension of the stop leg in the insertion direction can be kept to a minimum. Therefore, for example, when it is desired to install the mounting member in a box such as a console box provided in a vehicle, the storage section of the box can be maximized.

〈Example〉 Hereinafter, an example of the case where this invention is used in a console box of an automobile will be taken as an example.
However, the explanation is not limited to this.

The front end of the cover 13 of the console box 11 of the embodiment shown in Figures 1 to 4 is provided with a locking leg 14 having a head 14a at its tip that bulges in the left-right direction and has a shape generally similar to that of the conventional locking leg 4.

Furthermore, a locking hole 16 is provided at the front end of the box portion 15 at a position corresponding to the locking leg portion 14 .

The locking hole 16 is formed in a substantially rectangular cylindrical locking body 12 that is attached to the box portion 15, and this locking body 12 is provided with a flange portion 18 at the upper part. Claw portions 19, 19 that engage with the box portion 15 are provided protruding from the surface.

Further, elastic pieces 17, 17 are provided on the left and right side walls of the locking body 12 to narrow the width (left and right width) of the locking hole 16.
are protruding from opposite sides.

The neck 17a of the elastic piece 17 extends along the left or right inner peripheral surface of the locking hole 16 and in a direction perpendicular to the insertion direction of the locking leg 14,
The engaging portion 17b of the elastic piece 17 is formed to protrude inward in the left-right direction of the locking hole 16, so that the elastic piece 17 can swing elastically in a plane perpendicular to the insertion direction of the locking leg 14. ing. Note that the cross section of the neck of the elastic piece 17 is a vertically elongated rectangular shape as shown in the figure, so that the spring elastic deformation occurs in a plane perpendicular to the insertion direction of the locking leg 14, that is, in a horizontal plane. It is desirable to ensure that this is done within the company.

The engaging portion 17b has a substantially D-shaped cross section, with its substantially central portion in the vertical direction protruding most inwardly, and has a width l smaller than the maximum diameter L of the head of the locking leg portion 4 between the engaging portion 17b and the opposing engaging portion. A narrow portion having (l<L) is formed.

When the lid 13 is closed, the locking legs 14 of the lid 3 are inserted into the locking holes 16 of the box 15. When the head 14a of the locking leg 14 passes through a narrow portion with a width l, the elastic piece 17 on the outer side, that is, on the right side, moves to the right and to the left, using the base end side of the elastic neck parts 17a, 17a as a fulcrum. The elastic piece 17 will bend to the left.

Then, when the maximum diameter L portion of the locking leg head portion 14a passes through the narrow portion, the diameter of the head portion 14a gradually decreases, and the elastic pieces 17, 17 gradually become smaller.
It moves inward to return to its original state due to the elastic force, and the head 14a is locked by the engaging parts 17b, 17b, and the locking leg 14 is attached to the locking hole 16.

When the locking leg 14 is pulled out from the locking hole 16 in order to open the lid 13 after being attached as described above and the lid 13 is closed, if you try to pull the locking leg 14 upward, the locking Similar to when inserting the locking leg 14, the head 14a causes the elastic pieces 17, 17 to bend outward horizontally, widening the narrow portion, and allowing the locking leg 14 to be pulled out.

Therefore, the locking leg portion 1 disposed on the lid portion 13
4 into the locking hole 16, and when the locking leg 14 is pulled out from the state after being inserted into the locking hole 16, the elastic pieces 17, 17 are in the horizontal plane (of the locking leg). Since the structure allows the locking leg 14 to be bent outward in the left-right direction (in a plane perpendicular to the insertion direction), the locking leg 14 can be locked with the same force as when inserting the locking leg 14 into the locking hole 16. It can be pulled out from the stop hole 16, making the removal operation easier than in conventional structures.

In this embodiment, the elastic pieces 17, 17 are formed on both the left and right sides of the locking hole 16, but as shown in FIG. It is sufficient to simply form the elastic piece 27.
