Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coupling tool for rotatably coupling a rod-shaped link whose tip is bent in an L shape to a coupled member.

[0002]

[Prior art]

 A rod-shaped link is provided between the lock key lever and the door lock inside the vehicle door. As shown in FIG. 5, the rod-shaped link 2 is generally an elongated link rod and has an L-shaped tip portion 21. The rod-shaped link 2 is for remotely controlling the opening and closing of, for example, a door lock (not shown) at a remote place by operating a lock key lever 3 (see FIG. 4) at hand.

By the way, the tip portion 21 of the rod-shaped link 2 is engaged with the lock key lever 3 via the coupling 1. At this time, the connector 1 has a role of connecting the rod-shaped link 2 and the lock key lever 3. As shown in FIG. 5, the connector 1 has a link fitting hole 10 at one end for fitting the front end 21 of the rod-shaped link 2. Further, an engaging lower piece 101 is provided below the link fitting hole 10.

The lower engaging piece 101 has a slit 1011 and a locking claw 1012. The slit 1011 is for facilitating the engagement of the engaging lower piece 101 with the engaging hole 30 (see FIG. 4) provided in the lock key lever 3. The reference numeral 102 in FIG. 5 indicates a seat for stabilizing the engagement state of the engagement tool 1 when the engagement lower piece 101 is engaged with the engagement hole 30 of the lock key lever 3. On the other hand, the coupling 1 has, at the other end, a substantially U-shaped locking portion 12 for locking the rod-shaped link 2.

[0005]

[Problems to be solved]

 However, the above conventional technique has the following problems. That is, the coupling 1 and the rod-shaped link 2 are generally used in a narrow space such as an automobile door lock. Therefore, it is difficult to fit the tip end portion 21 of the rod-shaped link 2 into the link fitting hole 10 of the connector 1. Particularly, after fixing the other end of the rod-shaped link 2 to, for example, the door lock, guide the end 21 of the rod-shaped link 2 into the link fitting hole 10 of the connector 1 and fit it. Is an extremely difficult task.

As a result, it takes a long time to assemble the door, which may reduce the productivity of the vehicle door lock. The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a connecting tool having a simple structure and a simple structure even at a narrow working space such as an interior of a door of an automobile. Is.

[0007]

[Means for solving the problem]

 The present invention provides a connector having a link fitting hole for fitting an L-shaped tip of a rod-like link, wherein the rod-like member is provided at one side peripheral edge of the link fitting hole in the joining device. A connector is provided with a guide wall for guiding the tip of the link into the link fitting hole.

One end of the guide wall is erected so as to surround, for example, about one third of the peripheral edge of the link fitting hole. Further, the guide wall is preferably formed integrally with the main body of the coupling tool. Thereby, the guide wall can be easily formed.

The coupling tool has the link fitting hole at one end, for example. At the other end, for example, there is a substantially U-shaped locking part for locking the middle part of the rod-shaped link. Further, the other end of the guide wall is erected so as to extend from the locking portion to one peripheral edge of the link fitting hole (see FIG. 1). The above-mentioned coupling tool is integrally formed of, for example, synthetic resin.

[0010]

[Action and effect]

 In the connector of the present invention, the guide wall is provided on the peripheral edge of one side of the link fitting hole. Therefore, when the rod-shaped link is fitted into the link fitting hole, the tip of the rod-shaped link is first set in the above state with the lower engaging piece of the fitting engaged in the engaging hole of the connected member in advance. Contact the guide wall. Then, the tip end of the rod-shaped link is moved along the guide wall toward the link fitting hole (see FIG. 2). Next, insert the tip of the rod-shaped link into the link fitting hole and fit it. After that, for example, the rod-shaped link is rotated around the tip end of the rod-shaped link as an axis to lock the rod-shaped link in the locking portion (see FIG. 3). This allows the rod-shaped link to be connected to the connector quickly and easily. Therefore, according to the present invention, it is possible to provide a coupling tool having a simple link tip and a simple structure even in a narrow working space such as the inside of a vehicle door.

【Example】

 Embodiment 1 A coupling tool according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 to 3, the connector 1 has a link fitting hole 10 for fitting the L-shaped tip portion 21 of the rod-shaped link 2. The coupling tool 1 is used for mounting the rod-shaped link 2 on the door lock key lever 3 of an automobile. As shown in FIG. 1 and FIG. 2, a guide wall for guiding the tip end portion 21 of the rod-shaped link 2 to the link fitting hole 10 is provided at one peripheral edge portion of the link fitting hole 10 in the coupling tool 1. 11 is provided.

As shown in FIGS. 1 to 4, the coupling 1 has a link fitting hole 10 at one end. The other end has a substantially U-shaped locking portion 12 for locking the rod-shaped link 2. Further, the above-mentioned coupling 1 is made of a synthetic resin molded body such as polypropylene resin. As shown in FIGS. 1 to 4, the guide wall 11 is erected so as to extend from the locking portion 12 to a peripheral edge portion on one side of the link fitting hole 10. The guide wall 11 is formed integrally with the main body of the connector 1. An engaging lower piece 101 is provided below the guide wall 11. The lower engaging piece 101 is for engaging with the engaging hole 30 of the lock key lever 3 (FIG. 4). As a result, the lock key lever 3 and the rod-shaped link 2 can be connected.

As shown in FIGS. 1 to 3, the lower engaging piece 101 has a slit 1011 and a locking claw 1012. As shown in FIG. 4, the slit 1011 is for facilitating the engagement of the lower engaging piece 101 with the engaging hole 30 provided in the lock key lever 3 which is the member to be connected.

As shown in FIGS. 1 and 2, the locking portion 12 has a side wall 121 connected to one end of the guide wall 11. An opening 120 for inserting the rod-shaped link 2 is provided on the side facing the side wall 121. Above the opening 120, there is a locking piece 122 for locking the rod-shaped link 2. Next, the function and effect will be described. In the connector 1 of this example, as shown in FIGS. 1 to 3, a guide wall 11 is provided at one peripheral edge of the link fitting hole 10.

Therefore, when the rod-shaped link 2 is fitted into the link fitting hole 10, the engagement lower piece 101 of the coupling tool 1 is previously engaged with the engagement hole 30 of the lock key lever 3 which is the member to be coupled. In this state (FIG. 4), as shown in FIG. 2, the tip portion 21 of the rod-shaped link 2 is first brought into contact with the side surface of the guide wall 11. Next, the tip portion 21 of the rod-shaped link 2 is moved along the inside of the guide wall 11 toward the link fitting hole 10. Next, the tip portion 21 of the rod-shaped link 2 is fitted into the link fitting hole 10. After that, as shown in FIG. 3, the rod-shaped link 2 is rotated in the direction of the arrow with the tip portion 21 of the rod-shaped link 2 as the axis, and the rod-shaped link 2 is locked in the locking portion 12.

As a result, the rod-shaped link 2 can be quickly and easily connected to the lock key lever 3. In this state, the rod-shaped link 2 can rotate integrally with the coupling tool 1 without coming out of the engagement hole 30 of the lock key lever 3.

Therefore, according to the present embodiment, it is possible to obtain a connector in which the tip of the link is easily fitted and convenient even in a narrow working space such as the inside of the automobile door. In addition, the efficiency of automobile door assembly work can be improved and productivity can be increased.
