Description

[Detailed Description of the Invention] The present invention relates to a vibration-proof holder that prevents noise caused by the vibration of wire rods often used in automobiles and the like. A long wire-like rod, which is mainly used to transmit tensile force, is often used as a means of transmitting force applied to an operating lever, such as in a car door lock unlocking device or a trunk compartment lid unlocking device. . However, in order to improve assembly efficiency, the ends of these wire rods are formed in advance into the shape necessary for engagement of these rods with other mechanisms, and are then incorporated into other mechanisms. is common. Therefore, the area of the rod insertion hole drilled in the rod holding piece provided on the other mechanism side that engages with these rods is limited to the area of the rod insertion hole, since it is necessary to insert the bent rod when assembling the rod. The rod needs to be 4 to 5 times larger than the cross-sectional area, but after installation, this large diameter hole causes the rod to vibrate significantly, causing noise and making it difficult to unlock the car door lock. In the case of a commercial rod, it may vibrate during operation, causing a harsh sound.
This was the cause of what is called a rattling sound. As a measure to prevent such rattling noise, coating the end of the rod with resin has been considered, but although the sound changes slightly, this has not yet been eliminated. The present invention was developed in view of these circumstances, and its gist is that a rod holder made of a rubber or plastic fitting is fitted onto a holding piece that holds the rod after the rod has been assembled, and the rod The purpose is to prevent movement in the radial direction. Hereinafter, the case of a rod for unlocking a car door lock will be explained in detail as an example.

A force applied to a doorknob (not shown) is transferred to a wire-like rod 10 having a length approximately equal to the width of the door through an inner lock device R as shown in FIG.
Then, it is transmitted as a tensile force in the direction of the arrow E to unlock a door lock device (not shown) connected to the other end of the door lock unlocking rod 10. By the way, in the inner lock device R, by pushing down the knob 11 protruding from the window edge 30 of the door in the direction of the arrow D, the hook 13 pivoted on the lever 12 linked to the doorknob rotates. The engagement with the tip of the rod 10 bent into a U-shape is released, and the unlocking mechanism is configured not to operate. The unlocking rod 10 is held in a rod insertion hole 17 formed in the holding piece 16 by a holding piece 16 provided at the bottom of a mounting plate 15 that pivotally supports the lever 12. 18 is a guide groove for the rod 10. The anti-vibration holder 1 of the present rod has an insertion hole 17 into which a wire-shaped door lock unlocking rod 10 is inserted and held.
It is used by being fitted onto the holding piece 16 having a
When fitting the anti-vibration holder 1 to the holding piece 16 around a plate made of a material such as rubber, the edge 4 on one side that should serve as the entrance of the holding piece is left as it is. A fitting groove 7 is formed by erecting a fitting edge 2 having a substantially L-shaped cross section on the other peripheral edge of the plate. When the fitting groove 7 is fitted into the holding piece 16, a rod holding hole 3 having approximately the same diameter as the rod 10 is formed within the range where it comes into contact with the rod insertion hole 17 of the holding piece 16.
A notch 5 is formed to communicate between the rod holding hole 3 and the edge 4 having no fitting groove, and a reinforcing edge 6 is provided protruding around the rod holding hole 3. It consists of The reinforcing edge 6 can be omitted if the vibration-proof holder has a sufficient wall thickness. In the above embodiment, as is clear from FIG. 5, one side has a U-shaped fitting edge (fitting groove).
is provided, and a rod holding hole and a notch are formed on the other side, but it is also possible to form a rod holding hole and a notch on both opposing surfaces of a sheath-shaped fitting body. The anti-vibration holder of the present invention can be manufactured at an extremely low cost by injection molding.
In addition, it is extremely efficient because it can be fitted into the holding piece in one operation, and the rod insertion hole provided in the holding piece can be made large so that the rod can be easily inserted. , improving assembly efficiency. By attaching the rod anti-vibration holder of the present invention, vibrations peculiar to wire rods can be completely suppressed, and unpleasant noises can be eliminated.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A wire-like rod is used by being fitted into a holding piece that is held in an insertion hole, and the wire rod is used by fitting it into a holding piece that is held in an insertion hole, and the rod is attached to the periphery of a plastic or rubber plate that has approximately the same shape as the holding piece. ,
A fitting groove is formed by erecting a fitting edge with a substantially L-shaped cross section on the other peripheral edge, except for one side edge that should serve as an entrance for the holding piece when fitting into the holding piece. A rod holding hole having approximately the same diameter as the wire-like rod is bored within a range that contacts the rod insertion hole of the holding piece when the fitting groove and the holding piece are fitted together, and the rod holding hole is A vibration-proof holder of a wire-like rod, which has a notch that communicates with the one end edge that does not have a fitting groove. (2) The vibration-proof holder according to claim 1, further comprising a reinforcing edge protruding around the rod holding hole.
