Detailed Description
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The embodiments described below are examples of devices and the like for embodying the technical concept of the present invention, and the material, shape, structure, arrangement, and the like of each component in the technical concept of the present invention are not limited to the following. The technical idea of the present invention can be variously modified within the scope of the claims.
Fig. 3 to 7B show an embodiment of the present invention. The vehicle body panel 1 as the mounted member includes: a horizontal surface 2 as a 1 st installation surface; and an inclined surface 3 as a 2 nd mounting surface inclined with respect to the horizontal surface 2. That is, the vehicle body panel 1 includes mounting surfaces having different surface directions. The horizontal surface 2 and the inclined surface 3 are opened with mounting holes 4 and 5, respectively.
The protector 10 has: a protector body 11 having an electric wire accommodating chamber therein; and a cover 12 that closes the upper surface opening of the protector body 11. The protector body 11 has a 1 st mounting portion 20 and a 2 nd mounting portion 30 at 2 positions corresponding to the mounting holes 4 and 5 of the vehicle body panel 1 in the bottom surface portion thereof.
The basic structure of the 1 st and 2 nd mounting parts 20 and 30 will be described. The 1 st mounting part 20 and the 2 nd mounting part 30 each have: bases 21, 31, and jigs 23, 33 protruding from the bases 21, 31. The bases 21 and 31 are square frames. A pair of spring portions 22a, 22b, 32a, and 32b protrude from the bottom surfaces 21a and 31a of the bases 21 and 31 toward the blade portion 25 described below. Each spring portion 22a, 22b, 32a, 32b is a cantilevered support structure.
Each of the jigs 23, 33 has: shaft portions 24, 34 protruding from bottom surfaces 21a, 31a of the bases 21, 31; a pair of blade portions 25, 35 projecting to the sides of the shaft portions 24, 34; and a pair of locking ribs 26, 36 protruding from the upper ends of the blade portions 25, 35 toward the bases 21, 31. A pair of relief grooves 24a, 34a (see fig. 5A, 5B) that allow elastic deformation of the blade portions 25, 35 are formed in the side surfaces of the shaft portions 24, 34. Each blade portion 25, 35 is formed in a tapered shape gradually widening from the tip of the shaft portion 24, 34 toward the root. The blade portions 25 and 35 are elastically deformable in a direction of narrowing in a tapered shape by the relief grooves 24a and 34 a. The upper end surfaces of the blade portions 25, 35 are formed as contact surfaces 25a, 25b, 35a, 35b, respectively, which come into contact with each other when attached to the vehicle body panel 1. The locking ribs 26 and 36 extend from the inner peripheral ends of the upper end surfaces of the vane portions 25 and 35 toward the base 21. Each of the locking ribs 26, 36 is arc-shaped.
Next, the specific structural parts of the 1 st mounting part 20 and the 2 nd mounting part 30 will be described.
The jig 23 of the 1 st mounting portion 20 is formed in an insertion direction (axial direction of the jig 23) F1 into the mounting hole 4 in a direction perpendicular to the horizontal plane 2. The jig 33 of the 2 nd mounting portion 30 is also formed in an insertion direction (axial direction of the jig 33) F1 into the mounting hole 5 in a direction perpendicular to the horizontal plane 2, similarly to the jig 23 of the 1 st mounting portion 20. That is, the directions of the shaft portions 24, 34 of the respective jigs 23, 33 of the 1 st and 2 nd mounting portions 20, 30 are formed in the same direction F1.
The jig 23 and the base 21 of the 1 st mounting portion 20 are formed in a horizontal direction so as to sandwich and fit the vehicle body panel 1. On the other hand, the jig 33 and the base 31 of the 2 nd mounting portion 30 are inclined in an inclined direction with respect to the horizontal direction so as to sandwich the vehicle body panel 1 and fit the same. That is, the directions in which the body panel 1 is sandwiched and fitted are set to be different directions in the 1 st fitting part 20 and the 2 nd fitting part 30, respectively.
Specifically, as shown in fig. 6A and 6B, the bottom surface 21a of the base 21 of the 1 st mounting portion 20 is formed along the horizontal direction. The bottom surface 21a of the base 21 is formed to have the same height in the left and right. The pair of spring portions 22a and 22b protrude from the bottom surface 21a having the same height in the left and right. The contact surfaces 25a and 25b of the pair of blade portions 25 are also formed to have the same height. Thereby, it is formed as: the pair of spring portions 22a, 22b abut against the horizontal surface 2, and the abutting surfaces 25a, 25b of the pair of blade portions 25 of the 1 st mounting portion 20 abut against the opposite surface of the horizontal surface 2.
As shown in fig. 7A and 7B, the bottom surface 31a of the base 31 of the 2 nd mounting portion 30 is formed in an inclined direction. The bottom surface 31a of the base 31 is formed to be low on the left side and high on the right side. The pair of spring portions 32a and 32b protrude from the bottom surface 31a having different left and right heights. The contact surfaces 35a and 35b of the pair of blade portions 35 are formed to be low on the left side and high on the right side. Thereby, it is formed as: the pair of spring portions 32a and 32b abut against the inclined surface 3, and the abutment surfaces 35a and 35b of the pair of blade portions 35 of the 2 nd mounting portion 30 abut against the opposite surface of the inclined surface 3.
Next, an operation of attaching the protector 10 to the vehicle body panel 1 will be described. As shown in fig. 3, the positions of the 1 st mounting portion 20 and the 2 nd mounting portion 30 of the protector 10 are aligned with the positions of the 2 mounting holes 4 and 5 of the vehicle body panel 1, and the jigs 23 and 33 are inserted into the mounting holes 4 and 5, respectively. Accordingly, the pair of blade portions 25, 35 of the jigs 23, 33 are elastically deformed in the direction of approaching each other to allow the pair of blade portions 25, 35 to be inserted into the mounting holes 4, 5. The pair of spring portions 22 and 32 abut against the body panel 1 while the pair of blade portions 25 and 35 enter the respective mounting holes 4 and 5. The pair of blade portions 25, 35 are gradually inserted into the mounting holes 4, 5 against the elastic force of the pair of spring portions 22, 32, and when the contact surfaces 25a, 25b, 35a, 35b of the pair of blade portions 25, 35 are pulled out from the respective mounting holes 4, 5, the pair of blade portions 25, 35 are elastically restored and deformed. Thus, in the 1 st mounting portion 20 and the 2 nd mounting portion 30, the pair of spring portions 22a, 22b, 32a, 32b and the pair of blade portions 25, 35 sandwich the vehicle body panel 1, and prevent movement in the insertion/removal direction (positioning in the insertion/removal direction) to the respective mounting holes 4, 5. In the first and second mounting portions 20 and 30, the pair of locking ribs 26 and 36 are pressed against the inner circumferential surfaces of the mounting holes 4 and 5 by the elastic restoring forces of the blade portions 25 and 35, and are prevented from moving in the surface directions of the body panel 1 (positioned in the surface directions). Thus, the protector 10 is fitted in a state where the vehicle body panel 1 is sandwiched between the 1 st mounting portion 20 and the 2 nd mounting portion 30. At this time, the mounting operation of the protector 10 is completed.
As described above, the insertion direction of the jigs 23 and 33 of the 1 st and 2 nd mounting portions 20 and 30 into the mounting holes 4 and 5 is set to the same orientation so as to match the surface direction of one mounting surface (horizontal surface 2 in the present embodiment) of the vehicle body panel 1, and the direction in which the jigs 23 and 33 of the 1 st and 2 nd mounting portions 20 and 30 and the bases 21 and 31 sandwich the vehicle body panel 1 is set to a different orientation so as to match the surface direction of each of the horizontal surface 2 and the inclined surface 3, which are the mounting surfaces.
In the protector 10, since the insertion directions F1 of the jigs 23 and 33 of the 1 st and 2 nd mounting portions 20 and 30 are the same, the jigs 23 and 33 can be smoothly inserted into the mounting holes 4 and 5, and the insertion workability is good. Since the jigs 23 and 33 and the bases 21 and 31 of the 1 st and 2 nd mounting portions 20 and 30 form the mounting surfaces, i.e., the horizontal surface 2 and the inclined surface 3, in a direction in which the vehicle body panel 1 is sandwiched and fitted, the mounting can be performed in a firmly fitted state.
The protector main body 11 is manufactured by injection molding using a mold. As shown in fig. 3, since the insertion direction F1 of the jig 23 of the 1 st mounting part 20 and the insertion direction F1 of the jig 33 of the 2 nd mounting part 30, that is, the axial directions of the jigs 23 and 33 are the same, the mold can be made common by making the mold releasing directions of the 1 st mounting part 20 and the 2 nd mounting part 30 the same, and thus the mold cost can be reduced compared to the conventional one. That is, in the conventional example, as shown in fig. 1, since the insertion direction (axial direction of the jig 71) F1 of the jig 71 of the 1 st mounting part 61 and the insertion direction (axial direction of the jig 71) F2 of the jig 71 of the 2 nd mounting part 62 are different, the mold release directions of the 1 st mounting part 61 and the 2 nd mounting part 62 cannot be the same, and different molds are required, which increases the mold cost.
Although the mounted member is the vehicle body panel 1 in the above embodiment, the present invention is applicable even if the mounted member is a member other than the vehicle body panel 1.
In the above embodiment, the mounting surfaces of the vehicle body panel 1 having different surface directions are the horizontal surface 2 as the 1 st mounting surface and the inclined surface 3 as the 2 nd mounting surface inclined with respect to the 1 st mounting surface, but the present invention can be applied to a case where both of them are inclined surfaces. In this case, the insertion direction of the jigs 23 and 33 of the mounting portions 20 and 30 into the mounting holes 4 and 5 (the axial direction of the jigs 23 and 33) is set to be the same direction as the surface direction of any one of the inclined surfaces.
In the above embodiment, the number of the mounting surfaces having different surface directions of the vehicle body panel 1 is 2, but the present invention can be applied even if the number of the mounting surfaces having different surface directions is 3 or more.
In the above embodiment, the mounting portions of the protector 10 are 2 portions of the 1 st mounting portion 20 and the 2 nd mounting portion 30, but the present invention can be applied even if the mounting portions are 3 or more.
In the above embodiment, the bases 21 and 31 have the pair of spring portions 22a, 22b, 32a, and 32b, and the jigs 23 and 33 are constituted by the shaft portions 24 and 34, the pair of blade portions 25 and 35, and the pair of locking ribs 26 and 36, but any configuration may be used as long as the structure can sandwich and fit the vehicle body panel 1.
The present invention is not limited to the above embodiments, and can be carried out by changing the constituent elements in the implementation stage within a range not exceeding the gist thereof. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments.
