Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a rod holder for holding an operating rod or the like linked to an inside handle or an outside handle in a vehicle door lock device, for example.

[0002]

[Prior art]

 As conventional holders of this type, there are, for example, those shown in Japanese Utility Model Publication No. 64-46508 and Japanese Utility Model Publication No. 1-148475. These conventional rod holders have some structural differences, but they are all made of synthetic resin, and basically they hold the fixed part attached to the door panel and the operation rod etc. slidably. In particular, a pair of elastic lip pieces for elastically holding the rod from above and below are integrally formed on the holding portion side.

In actual use, first, the fixing portion is inserted into the mounting hole of the door panel, the holder itself is fixed to the door panel side, and then the rod is accommodated in the holding portion. Will be held irremovably. Moreover, in such a holding state of the rod, since the rod is elastically held from above and below by the pair of elastic lip pieces described above, smooth sliding motion in a predetermined direction is allowed and at the same time, Even if vibrations of the automobile are applied, it is possible to prevent unpleasant rattling and generation of unpleasant noise.

[0004]

[Problems to be solved by the device]

 However, in the conventional rod holder, even if the pair of elastic lip pieces are formed so as to extend outward from the holding portion or be formed in the holding portion in mutually opposite directions, these Since the elastic lip piece is formed by extending it in a thin shape, it is easy to get worn out when it is affected by heat.Therefore, in a long-term use, if the elastic force on the rod is significantly reduced and running vibration etc. is added, There was a risk of rattling and producing abnormal noise.

[0005]

[Means for Solving the Problems]

 The present invention was developed in order to effectively solve the problems of the conventional rod holder, and is made of a synthetic resin rod that includes a fixing portion that is attached to the panel and a holding portion that slidably holds the rod. Assuming a holder, we adopted a configuration in which a soft layer is provided inside the above-mentioned holding part that directly holds the rod.

[0006]

[Action]

 Therefore, according to the present invention, the rod can be securely held in the holding portion only by providing the soft layer inside the holding portion without forming the elastic lip piece which is easily damaged due to heat influence. Therefore, the durability of the rod holder itself against heat can be improved.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. The rod holder according to the first embodiment is made of a synthetic resin material as in the conventional case. As shown in FIG. It is composed of a fixed part 1 attached to the base plate and a holding part 2 that slidably holds the rod. The feature is that the following configuration is adopted. That is, in the first embodiment, as shown in the figure, the fixing portion 1 has a normal anchor leg shape, and the holding portion 2 has a horizontal U-shape, and the holding portion 2 having the horizontal U-shape. A guide piece 3 for facilitating rod insertion and a projection 4 for preventing rod disengagement are provided on the upper opening edge side of the rod holder, and the entire rod holder is molded with a relatively hard synthetic resin material such as polyacetal. A structure in which a soft layer 5 of substantially the same shape and width formed of a soft synthetic resin material such as elastomer urethane is attached in a superposed state to the inside of the horizontal U-shaped holding portion 2 that holds the rod in the vertical direction. It is what was done.

Regarding the attachment of the soft layer 5, as shown in the figure, the soft layer 5 itself is independently molded into a shape similar to the inside of the holding portion 2 with the resin material or the like, and the soft layer 5 is formed. After that, it is attached to the inside of the holding portion 2 in an overlapping state via an adhesive, or as shown in FIG. 2A, a flange wall portion 2a is formed inside the holding portion 2 and the flange wall portion 2a is used. Then, the soft layer 5 is attached in a polymerized state by insert molding, or as shown in B of the same figure, a plurality of connecting holes 2b are formed on the holding portion 2 side and the same number of connecting protrusions are formed on the soft layer 5 side. 5a is formed and the connecting projections 5a are fitted into the connecting holes 2b, whereby the separately molded soft layer 5 is attached inside the holding portion 2 in a superposed state. Of course, it is possible to use any method.

Therefore, even when the rod holder of the first embodiment is used, as shown in FIG. 3, the anchor 1-shaped fixing portion 1 is inserted into the mounting hole H of the door panel P, and the holder itself is inserted. After being fixed to the door panel P side, if the rod R is housed in the holding portion 2 with the help of the guide piece 3, the rod R is elastic holding force from the vertical direction obtained from the horizontal U-shape of the holding portion 2. Since it is pressed down, it is securely held in the holding portion 2.

In addition, in the holding state of the rod R, the soft layer 5 having the same shape and the same width is attached in a superposed state to the inside of the holding portion 2 that directly abuts the rod R. Therefore, the presence of the soft layer 5 minimizes the sliding resistance to allow the smooth sliding movement of the rod R in the predetermined direction, and at the same time, it causes the rattling even if the traveling vibration is applied. Although it is possible to effectively prevent the generation of sound, it is not necessary to form an elastic lip piece that is easily affected by heat as in the conventional case, so the durability against heat is far superior to the conventional case. Even if it is used for a long period of time, it is possible to eliminate the fear that the rod R rattles and produces abnormal noise.

Next, the rod holder according to the second embodiment will be described. The second embodiment basically assumes the configuration of the first embodiment, but is different. As shown in FIG. 4, when the soft layer 5 is formed into a horizontal U shape similar to the inside of the holding portion 2, the height dimension of the horizontal U shape is narrowed to form the soft layer. It is configured such that the space 6 is positively defined between the upper and lower surfaces of 5 and the corresponding inner surfaces of the holding portion 2. The method of attaching the soft layer 5 to the holding portion 2 is similar to that of FIG. 2B, in which a plurality of connecting holes 2b are formed in appropriate places on the holding portion 2 side and the same number of connecting protrusions are formed on the soft layer 5 side. 5a is formed, and the connecting protrusions 5a are fitted into the connecting holes 2b, whereby the soft layer 5 is attached to the inside of the holding portion 2 while individually defining the spaces 6. .

Therefore, even in the rod holder of the second embodiment, as shown in FIG. 5, the anchor portion-shaped fixing portion 1 is inserted into the mounting hole H of the door panel P to fix the holder itself. If the rod R is housed in the holding part 2 with the help of the guide piece 3 after being fixed to the door panel P side, the rod R will be held in the holding part 2 in an unseparable manner. Under the second embodiment, since the spaces 6 are individually defined between the upper and lower inner surfaces of the holding portion 2 and the soft layer 5, the soft layer 5 itself is separated from the inside of the holding portion 2 and is hard. Since it is less likely to be affected by the holding portion 2, it is possible to minimize the change in sliding resistance due to the operation of the rod R. Even in the second embodiment, it is needless to say that the presence of the soft layer 5 can prevent the rod R from rattling and generating abnormal noise.

[0013]

[Effect of device]

 As described above, according to the present invention, by adopting the above-described configuration, even if the elastic lip piece that is easily damaged by heat is not formed, it is only necessary to provide the soft layer on the inside of the holding portion, and the rod can be used for a long time. Since it can be securely held in the holding part without rattling, this can be expected to greatly improve the durability of the rod holder itself. Therefore, according to the present invention, it is possible to prevent the rattling of the rod for a long period of time, and thus it is possible to provide a rod holder having an excellent soundproof effect.
