Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in a rod holder for fixing one end of the rod to a support.

For example, an outdoor handle of a car and a door lock device are connected by a rod, and when the outdoor handle is operated, the door lock device is opened and closed via the rod. In this case, a rod holder molded from plastic to connect and fix one end of the rod to the outdoor handle is covered by British Patent No. 1589933.
proposed in the specification. This rod holder includes a cylindrical body having a through hole with an inner diameter equal to the diameter of the rod, and a flange projecting outward from the outer periphery of the upper end, and a pair of anchors ( Anchor)-shaped locking piece.
For this reason, it is possible to push the cylindrical body into the mounting hole of the outdoor handle, fix the cylindrical body to the outdoor handle first using the collar and locking piece, and then insert the rod into the through hole of the cylindrical body, or vice versa. It is also possible to first insert and place the rod into the through hole of the cylindrical body, and then push the cylindrical body into the attachment hole of the outdoor handle and fix it. However, since this rod holder must be inserted with the outer circumference of the rod in sliding contact with the entire inner circumference of the through-hole of the cylindrical body, frictional resistance is large, and a considerable amount of force is required to insert the rod into the through-hole. . In addition, since the pair of anchor-shaped locking pieces grow diagonally upward from the lower end of the cylindrical body, separate from the cylinder, a large amount of plastic is required to mold the cylinder and the locking pieces. minutes,
The cost will be high.

Therefore, the present invention provides a rod holder consisting of a cylindrical body made of plastic and having a through hole in the center and a flange projecting outward on the outer periphery of the upper end, in which the inner diameter of the through hole is made larger than the diameter of the rod. A plurality of slots are formed in the circumferential side wall of the cylindrical body at equal intervals in the circumferential direction, and each slot extends diagonally upward from the lower end of the cylindrical body, overhangs the outer periphery of the cylindrical body, and is connected to the bottom surface of the flange. A locking piece is provided for holding the body on the holding body, and protrusions are provided on the inner periphery of the cylindrical body and protrude inward at equal intervals in the circumferential direction, avoiding the slot, and the protrusions are provided with The straightness of the inscribed circle is made equal to the rod, and the amount of inward protrusion of the protrusion from the outer periphery of the cylinder is such that when the cylinder is pushed into the mounting hole of the support, it is pushed by the hole edge and pulled into the slot. It is characterized in that the retraction amount is equal to or greater than the retraction amount of the locking piece.

As a result, the rod holder of the present invention can also be used by first fixing the cylindrical body to the outdoor handle and then inserting the rod later, or conversely, by first inserting the rod into the cylindrical body. The cylinder can be fixed to the outdoor handle later, but when inserting the rod, attach the outer periphery of the rod to the inner surface of the protrusions that protrude inward at equal intervals in the circumferential direction from the inner periphery of the cylinder. Since it simply slides into contact with the connector, there is little frictional resistance, making insertion and installation very easy. The cylindrical body has a plurality of slots arranged at equal intervals in the circumferential direction on the circumferential side wall, and the locking pieces extend obliquely upward from the lower end of each slot and overhang from the outer periphery of the cylindrical body. At the same time, the protrusion extends inward from the inner periphery of the cylindrical body, avoiding the slot. In other words, the locking piece is formed using a part of the circumferential wall of the cylindrical body,
Since the protrusion that holds the rod only partially protrudes from the inner periphery of the cylinder, the amount of plastic required for molding can be reduced.

An illustrated embodiment of the present invention will be described below.

Reference numeral 1 denotes a cylindrical body having a through hole 2 in the center and a flange 3 protruding outward on the outer periphery of the upper end, and is molded from plastic. The through hole 2 is for passing the bent end 4' of one end of the rod 4 from above.
If necessary, a part of the flange 3 is extended outward, and a gripping part 5 for gripping the rod 4 is integrally provided on the extended piece 3', as in, for example, Uts. 47-17066 and 51-23677. .

However, this extension piece 3' and the gripping part 5
It may be omitted as shown in -90326. Most of the region 2a from the upper end of the cylinder of the through hole 2 to near the lower end has a diameter R that is somewhat larger than the diameter of the rod 4;
is open with a diameter r equal to the diameter of the rod 4. The through hole 2 has a plurality (four in this case) of inwardly protruding protrusions 6 arranged at approximately equal intervals in the circumferential direction in most of the region 2a. The circle inscribed in 6... is the region 2 of the lower end of the through hole.
It is approximately equal to the diameter r of b.

The cylindrical body 1 has a plurality of radial slits 7 communicating with the through-holes arranged at approximately equal intervals in the circumferential direction on the circumferential side wall, and a locking piece 8 extends diagonally upward from the lower end of each slit 7. Each locking piece 8 extends outward from the outer surface of the cylindrical body, and each locking piece 8 faces the lower surface of the collar 3 with a diagonally upwardly facing shoulder 8' at a constant distance.

A support body, for example, the outdoor handle 9, is provided with a mounting hole 9' having a diameter equal to or slightly larger than the outer diameter of the cylinder body 1, and in order to connect the rod, the cylinder body is opened from the lower end through this mounting hole 9'. ’. In this case, each locking piece 8 protruding from the outer surface of the cylinder is once pushed into the slot 7 by the hole edge and retracted, but when the lower surface of the collar 3 comes into contact with the upper surface of the support, the locking pieces 8 are elastically pulled back into the cylinder. An upwardly slanting shoulder 8' extending from the outer surface of the tube engages with the edge of the hole from below, pinching the support body between the collar and holding the cylinder body against the support body in a way that it cannot be pulled out.

The amount of protrusion of the above-mentioned protrusions 6 from the outer periphery of the cylinder is as follows:
In this way, when the cylinder is pushed into the mounting hole 9' of the support, the inner surface of the locking piece 8, which is pushed by the edge of the hole and pulled into the slot 7, is set so that it does not enter the circle inscribed in the protrusion 6. There is.

Therefore, according to the present invention, the end 4' of the rod is passed through the inside of the through hole 2 surrounded by the protrusion 6 and the inside of the lower end region 2b, and then the cylindrical body 1 is pushed into the mounting hole 9'. However, since the locking piece 8 can be retracted into the slot 7, the rod can be attached to the cylindrical body first, and then the cylindrical body together with the rod can be pushed into the mounting hole of the support body and fixed. Of course, it is also possible to first fix the cylinder to the support and then insert the rod into the cylinder to connect the rod and the support. Since the outer periphery of the end of the rod is brought into sliding contact with the protrusions 6..., the rod is inserted, so there is little frictional resistance, and the insertion is easy.
partially protrudes from the inner periphery of the through hole of the cylindrical body, and the locking piece 8 extends from the lower end of the slot 7 on the circumferential wall of the cylindrical body, and is formed in a form that partially utilizes the circumferential wall, making it easy to mold. The amount of plastic required can also be reduced.

As shown in the figure, the outer periphery of the lower end of the cylinder is tapered downward to facilitate insertion into the mounting hole, and the upper end of each protrusion 6 on the inner periphery of the through hole is tapered upward. It is desirable to allow the rod to be inserted easily.

Further, in this embodiment, an opening approximately equal to the outer diameter of the rod is provided in the lower end region 2b of the through hole, but this is not necessarily necessary, and the entire length of the inner circumference of the through hole is set to be slightly smaller than the outer diameter of the rod. Make the diameter R as large as possible,
Moreover, the protrusions 6 may be made to protrude inward.
