Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cushion rubber that is attached to a peripheral portion of an opening / closing body or an opening that is closed by the opening / closing body, and that cushions an impact force applied to the opening / closing body or the peripheral portion of the opening when the opening / closing body is closed. .
[0002]
[Prior art]
An impact force applied to the opening / closing body or the periphery of the opening when the opening / closing body is closed is applied to the periphery of the opening / closing body such as the door 3 of the vehicle as shown in FIG. A cushion rubber 2 is attached to alleviate and prevent backlash of the opening / closing body.
Hereinafter, the cushion rubber 2 attached to the door 3 will be described.
[0003]
The cushion rubber 2 is made of a solid elastic material. As shown in FIG. 6, the cushion rubber 2 is provided at the truncated cone-shaped main body 21 whose front end abuts on the peripheral edge of the door opening when the door is closed, and the base end of the main body 21. A cylindrical fitting shaft portion 22 that fits into a mounting hole 41 provided in the panel 4 constituting the peripheral edge of the opening, and a mounting hole provided on the opposite side of the main body 21 across the fitting shaft portion 22. 41 is formed by a substantially inverted frustoconical locking portion 23 sandwiching the panel 4 at the peripheral edge of the mounting hole 41 with the main body 21, and by inserting the locking portion 23 into the mounting hole 41, Mounted.
[0004]
[Problems to be solved by the invention]
However, in the case of the cushion rubber 2 as described above, if the diameter of the locking portion 23 is increased, it may be difficult to come off after the locking portion 23 is inserted into the mounting hole 41 and attached. Since a large force is required to insert 23, the mounting workability is poor. However, if the diameter of the locking part 23 is reduced, it is easy to insert the locking part 23 into the mounting hole 41 and the mounting workability is good, but it is easy to come off when an external force acts on the peripheral surface of the main body 21.
Moreover, the slit which divides these from the latching | locking part 23 to the fitting axial part 22 in radial direction is provided, and it attaches easily by bending the latching | locking part 23 and the fitting axial part 22 in the width direction of a slit. There is something that can be done, but it is easy to come off as well.
SUMMARY OF THE INVENTION An object of the present invention is to provide a cushion rubber that has good workability and is difficult to come off.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the cushion rubber according to claim 1 is attached to a peripheral part of an opening that is closed by the opening / closing body or the opening / closing body, and is attached to the peripheral part of the opening / closing body or the opening when the opening / closing body is closed. A cushion rubber made of a solid elastic material for alleviating the applied impact force, and is a columnar or truncated cone-shaped main body, and a panel constituting the opening / closing body or the opening provided at the base end of the main body A cylindrical fitting shaft portion that fits into the mounting hole, and a locking portion that is provided on the opposite side of the main body across the fitting shaft portion and sandwiches the peripheral edge portion of the panel mounting hole with the main body. A part of the peripheral surface of the locking part protrudes in a direction perpendicular to the central axis of the locking part, and the surface on the main body side extends from the base end of the locking part and inclines to the opposite side of the main body. In addition, the surface opposite to the main body extends in the same plane as the tip of the locking portion. Characterized in that a guide piece of substantially triangular made a side view.
According to this invention, the guide piece is inserted into the mounting hole in a state where the central axis of the cushion rubber is inclined with respect to the central axis of the mounting hole, and the locking portion is rotated while the cushion rubber is rotated about the central axis. By pushing in, the cushion rubber can be easily attached.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The cushion rubber 1 is integrally formed of a solid elastic material. As shown in FIGS. 1 and 2, when the door is closed, the front end of the main body 11 abuts against the peripheral edge of the door opening, and the fitting shaft portion fitted into the mounting hole 41 provided in the panel 4 constituting the door. 12 and a locking portion 13 that is inserted into the mounting hole 41 and sandwiches the peripheral edge of the mounting hole 41 with the main body 11, and the locking portion 13 is inserted into the mounting hole 41. A guide piece 14 is provided to guide the movement.
[0008]
The main body 11 has a truncated cone shape that tapers toward the tip. The fitting shaft portion 12 provided at the base end 111 of the main body 11 has a cylindrical shape, and the diameter thereof is smaller than the diameter of the base end 111 of the main body 11.
[0009]
The locking portion 13 also has an inverted truncated cone shape that tapers toward the tip, and the diameter of the base end 131 is smaller than the diameter of the base end 111 of the main body 11 and larger than the diameter of the fitting shaft portion 12. Further, a guide piece 14 protrudes from a part of the peripheral surface, and the shape thereof is a substantially triangular shape in a side view. A surface 141 on the main body 11 side extends from the base end 131 and is inclined toward the opposite side to the main body 11. The surface 142 opposite to the main body 11 extends in the same plane as the tip 132, and the respective tips are in contact with each other.
[0010]
Next, the operation of the cushion rubber 1 will be described.
When the cushion rubber 1 is attached to the panel 4, as shown in FIG. 3, the cushion rubber 1 is first inclined with respect to the panel 4 so that the central axis thereof is inclined with respect to the central axis of the attachment hole 41. Then, the guide piece 14 is inserted into the attachment hole 41 with the guide piece 14 facing the attachment hole 41.
[0011]
Thereafter, as shown in FIG. 4, when the engaging portion 13 of the cushion rubber 1 is rotated around the central axis of the cushion rubber 1 while being pressed toward the mounting hole 41, the cushion rubber 1 has the central axis at the mounting hole 41. The cushion rubber 1 is attached in a state as shown in FIG. 1 while the peripheral edge of the locking portion 13 is inserted into the attachment hole 41 in order from a position close to the guide piece 14 while standing up in a direction overlapping with the central axis.
[0012]
Thereby, by inserting the guide piece 14 into the attachment hole 41, the insertion of the locking portion 13 into the attachment hole 41 is facilitated, and the cushion rubber 1 can be easily attached.
[0013]
In the embodiment of the present invention, the case where the cushion rubber 1 is attached to the door side has been described, but the cushion rubber 1 may be attached to the door opening side.
[0014]
【The invention's effect】
According to the cushion rubber of the present invention, a part of the peripheral surface of the locking part protrudes in a direction perpendicular to the central axis of the locking part, and the surface on the main body side extends from the base end of the locking part. Since the side opposite to the main body is inclined and the surface opposite to the main body is extended in the same plane as the tip of the locking portion, a substantially triangular guide piece is provided in a side view. The cushion rubber can be easily installed by inserting the guide piece into the mounting hole with the central axis inclined with respect to the central axis of the mounting hole, and pushing the locking part while rotating the cushion rubber around the central axis. be able to. In addition, it is hard to come off after installation.
