Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for fixing two members while positioning them.
[0002]
[Prior art]
As a method of fixing the two metal members so as to be removable, as shown in FIG. 7, the mounting member 2 is fixed to a predetermined position with a screw 3 with respect to the fixing member 1. In the figure, 4 is a rotation stopper that prevents the mounting member 2 from rotating, and 5a and 5b are screw holes. Alternatively, as shown in FIG. 8, a pair of holes 6 are formed in the fixing member 1, a leg 7 is formed in the mounting member 2, and the leg 7 is inserted into the hole 6 and then bent. The attachment member 2 is fixed to the member 1 at a predetermined position by caulking.
[0003]
[Problems to be solved by the invention]
In the former method, the mounting member is aligned so that the screw holes of both members coincide with each other, and then the screw is tightened with a screwdriver. Even in the latter method, the positions of the leg and the hole are aligned, and then the leg is bent and caulked using a jig or a tool.
[0004]
In any of the methods, positioning is necessary, and jigs and tools are further required, so that the mounting work is troublesome. In view of the above, an object of the present invention is to provide a member mounting structure that can easily fix two members without using a jig or a tool.
[0005]
[Means for Solving the Problems]
In order to position and fix the other member on the surface of one member, the problem-solving means according to the present invention includes a positioning piece that guides one member to a predetermined position while guiding the periphery of the other member; Cut and raised claws that engage with a recess formed in the other member and fix the other member are integrally formed.
[0006]
The positioning piece is formed by cutting and raising in accordance with the shape of the other member, and one side into which the other member is inserted is opened and the other side is closed so that the peripheral edge of the other member can be inserted. The other member is guided by the positioning piece, and its movement is restricted when it reaches a predetermined position, so that it is positioned at the predetermined position.
[0007]
The cut-and-raised claw is formed by being cantilevered so that the tip is lifted, and the movement of the other member in the insertion direction is not hindered by bending, but the movement in the reverse direction is taken out. For this, it engages with the concave portion to become a resistance, and functions as a retainer. The recess is a through hole or a recess.
[0008]
In the vicinity of the root portion of the cut and raised claw, a projecting piece cut in the opposite direction to the cut and raised claw is formed to increase the elastic force of the cut and raised claw. That is, when a force is applied to the cut and raised nail due to the presence of the projecting piece, the stress concentration on the root of the cut and raised nail can be relaxed, and the cut and raised nail is easily elastically deformed. Therefore, when inserting the other member, the cutting and raising claw can be bent with a light force.

DETAILED DESCRIPTION OF THE INVENTION
An attachment structure for positioning and fixing two members of the present invention will be described. As shown in FIGS. 1 to 4, a positioning piece 10 that guides the metal mounting member 2 to a predetermined position on the flat surface of the metal fixing member 1, and a cut and raised claw 11 that engages and fixes the mounting member 2. And are formed. In the attachment member 2, an engagement hole 13 in which the cut and raised claw 11 is engaged is formed in the bottom plate 12 facing the flat surface of the fixing member 1.
[0010]
The positioning piece 10 is formed by cutting and raising a part of the fixing member 1 and bending it. The positioning piece 10 includes a standing wall 14 perpendicular to the flat surface of the fixing member 1 and an upper wall 15 connected to the upright wall 14. The height from the flat surface to the upper wall 15 is set to be slightly larger than the thickness of the bottom plate 12 of the mounting member 2. The positioning piece 10 is formed in an L shape in accordance with the bottom plate 12 so as to surround the rectangular bottom plate 12 of the mounting member 2.
[0011]
Such a positioning piece 10 is disposed so as to face a predetermined position where the mounting member 2 is to be fixed. The space surrounded by the two positioning pieces 10 is open on one side and closed on the other side, the attachment member 2 can be inserted from one side, and movement is restricted on the other side. The distance between the standing walls 14 of the two positioning pieces 10 is made the same as or slightly larger than the width of the bottom plate 12 of the mounting member 2, and guides both side edges of the bottom plate 12 of the mounting member 2. Further, one side of the upper wall 15 of the positioning piece 10 is expanded upward so that the attachment member 2 can be easily inserted. Thereby, the positioning piece 10 has a function of guiding the mounting member 1 to a predetermined position.
[0012]
The cut-and-raised claw 11 is located in the center of the space surrounded by the two positioning pieces 10 and is formed by cutting and raising a part of the fixing member 1 into a long plate shape from one side to the other side. The cutting and raising claw 11 is in a cantilever state in which the tip is cut off and the root portion is connected, the tip is lifted to the surface side, and gradually increases from one side toward the other side.
[0013]
On both sides of the cut and raised claw 11, arch-shaped protruding pieces 16 cut out toward the back surface side are formed. As a result, both sides of the root portion 11a of the cut and raised claw 11 are cut out, and are not restricted by the fixing member 1 when the cut and raised claw 11 is bent.
[0014]
Next, a method for fixing the two members will be described. Both side edges of the bottom plate 12 of the mounting member 2 are aligned with the positioning members 10 and the mounting member 2 is pushed from one side to the other side. When both side edges are inserted into the positioning member 10 and guided, and the bottom plate 12 comes into contact with the cut and raised claw 11, the cut and raised claw 11 is pushed down by the bottom plate 12 and bent to the back side. When the bottom plate 12 is further inserted, the engagement hole 13 of the bottom plate 12 reaches above the cutting and raising claw 11. Then, since there is no restriction on the cut and raised claw 11, the cut and raised claw 11 is restored to its original state by the elastic force and enters the engagement hole 13. At this time, since the other side of the bottom plate 12 contacts the positioning piece 10, no further insertion is possible, and the bottom plate 12 is positioned at a predetermined position. Then, when the cut and raised claw 11 is engaged with the engagement hole 13, it is prevented from coming off, and the bottom plate 12 cannot move toward one side. In this way, the attachment member 2 is fixed at a predetermined position with respect to the fixing member 1.
[0015]
Here, the role of the overhanging piece 16 will be described. In general, when only the nail 20 as shown in FIG. 5 is cut and raised, the base portion 20a of the nail 20 is not completely separated from the fixing member 1, so that the length L1 of the main body portion of the nail 20 is shortened. . Since the amount of bending of the claw 20 is related to the length of this portion, the claw 20 becomes difficult to bend when the mounting member 2 passes over the claw 20, and as a result, a great amount of force is required to insert the mounting member 2. .
[0016]
On the other hand, as shown in FIG. 6, if projecting pieces 16 are provided on both sides of the cut and raised claw 11, both sides of the root portion 11a of the cut and raised claw 11 are separated from the fixing member 1 and easily deformed. The length L1 of the part is also longer than in the above case, and the ease of bending of the cutting and raising claw 11 is increased. Therefore, the cutting and raising claw 11 is easily bent by the passage of the attachment member 2, and the attachment member 2 can be inserted only by lightly pushing. In addition, since the protruding piece 16 protrudes in the direction opposite to that of the cut and raised claw 11, stress toward the surface side is applied to the protruding piece 16 conversely with the bending of the cut and raised claw 11 toward the back surface side. When the cutting and raising claw 11 is restored to the original state, the restoring force of the overhanging piece 16 acts, so that the restoration property of the cutting and raising claw 11 is enhanced and can be quickly returned.
[0017]
When removing the attachment member 2 from the fixing member 1, the cut and raised claw 11 is pushed down to push the attachment member 2 toward one side. The bottom plate 12 of the mounting member 2 passes upward while pressing the raising and lowering claw 11, the mounting member 2 comes out of the positioning piece 10, and the mounting member 2 is removed. At this time, since the gap 17 is formed between the positioning pieces 10 on the other side, the bottom plate 12 can be pushed to the one side from the gap 17 with the other hand at the same time as pressing the cutting and raising claw 11 with one hand. This makes it easier to remove.
[0018]
In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. The material of the two members is not limited to metal but may be made of plastic, as long as the cut and raised claw has elasticity. Further, the arrangement and shape of the positioning pieces may be made to correspond to the shape of the bottom plate of the mounting member.
[0019]
【The invention's effect】
As is clear from the above description, according to the present invention, the two members can be easily positioned and fixed by the operation of bringing one member to the other member without requiring a jig or a tool. Further, the combination of the cut and raised claw and the overhanging piece can effectively utilize the elasticity of the cut and raised claw, and can work smoothly with a light force.
[0020]
Since the positioning piece, the cut-and-raised claw, and the overhanging piece are formed by cutting and raising a part of one member, no fixing parts are required and the structure is simplified. be able to.
