Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The disclosed technology belongs to the field of mounting technology of a device for maintaining an automobile door in a locked state.

Thus, according to this invention, a bell crank is rotatably supported by a base plate attached to an inner panel of a door such as a rear door of an automobile with a screw, and a locking control rod connected to a knob is provided at one end thereof. The invention is related to a door locking assembly structure in which a base end of a rod connected to a lock device is pivotally supported at the other end, and in particular, a holder such as an arm or a clip curled on the base plate side. A structure of an automobile in which a rocking control rod is loosely inserted at least in the swinging direction of the rocking control rod through a predetermined gap so that the rocking control rod and the knob at the tip thereof do not fall when the door trim is assembled. It is a device.

<Prior Art> As is well known, safety measures for automobiles such as passenger cars are extremely important, and a door such as a rear door thereof is provided with a lock device for maintaining a locked posture in a closed state during traveling. The lock device is adapted to be operated via the door locking assembly by pushing the knob downwardly provided on the upper edge of the dough trim so as to be retractable and retractable.

As shown in FIG. 6, the door locking assembly 1 is a rocking control rod which integrally has a knob 5 at one end of a bell crank 4 pivotally supported by a pin 3 with respect to a base plate 2 so as to be pivotable. The lower end of 6 is pivotally supported via a pin 7 so as to be capable of relative pivotal movement, and the proximal end of a rod 8 connected to a lock device for a rear door (not shown) is pivotally movable so as to be able to advance and retreat via a pin 9. When the door locking assembly 1 is attached to a predetermined portion of the inner panel 11 of the door 10, the knob 5
The base plate 2 is attached to the base plate 2 with screws 25 so that the hole 13 for retracting and inserting is inserted between the door trim 14 and the inner panel 11 which are formed in advance.

However, as shown in FIG. 6, the door locking assembly 1 has the lower end of the locking control rod 6 and the basic end of the rod 8 pivotally mounted on the bell crank 4 via the pins 7 and 9. As shown in the figure, it is potentially impossible to always keep the rocking control rod 6 and the knob 5 in the upright posture with respect to the bell crank 4, and therefore, the long control rod 6 is not attached during the assembling work via the pin 7. Most of the time, the operator supports the door locking assembly 1 with one hand, especially the locking control rod 6, and the other hand supports the door trim 14 and the like during the assembling work. Therefore, it is difficult to work, and the door trim 14 with a large size and a certain weight is moved back and forth. There was a problem that work efficiency was poor because it was difficult.

In order to cope with this, for example, as shown in Japanese Utility Model Laid-Open No. 57-38064, a claw 16 cut and raised at the base end of the locking control rod 6 is provided as shown in FIG.
Further, a claw 16 'that is cut and raised is formed on the tip side of the bell crank 4, and as shown in FIG.
A pair of cut-and-raised claws 16 ', 16' are formed on the side so as to have a stopper function for falling into the locking control rod 6.

<Problems to be Solved by the Invention> However, in the conventional technology of the type, the structure of the door locking assembly 1 converts the raising / lowering operation of the knob 5 into the forward / backward movement of the rod 8 so that the pin 7 has a pivotal structure. Since the swivel motion is possible at the branch, the relative behavior swivel angle between the cut and raised claws 16 and 16 'is, for example, 35 °.
Therefore, even if the rocking control rod 6 is allowed to turn at a certain angle and does not turn 180 ° and fall down, the workability in assembling the door trim 14 is still avoided. The locking angle of the locking control rod 6 is kept as small as possible, and the door trim 14 has a retractable hole 13
However, there is a drawback in that it lacks generality such that it requires a considerable amount of skill to insert the knob 5.

To cope with this, for example, there is a problem that even if it is a snap type, it is not possible to prevent the fall of the conventional mode, and the nail 1
The work man-hour increased due to cutting and raising of 6 and 16 ',
As a result, there is a disadvantage that the cost becomes high.

The purpose of this invention is to solve the problem of the locking control rod falling down in the assembling work and the like in the door locking assembly based on the above-mentioned prior art, and when assembling the door trim to the door, the door locking assembly is used. B) to maintain a relatively optimal posture, and to prevent the locking control rod from falling down, and to maintain the predetermined posture required for assembly, and to attach the door trim to the door and the knob to the door trim. It is intended to provide an excellent door locking assembly structure for an automobile, which can be carried out smoothly and which is useful in the field of application of assembly technology in the automobile industry.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the structure of the present invention, which is based on the above-mentioned utility model registration claim, is pin-pivoted to a base plate attached to an inner panel in order to solve the above-mentioned problems. In the door locking assembly structure in which the base end of the locking control rod is pivotally supported at one end of the crank and the base end of the rod to the locking device is pivotally supported at the other end, at least the locking control rod is attached to the base plate. The technical means is provided with a holder that is loosely inserted in the swinging direction through a predetermined gap.

<Action> Thus, the bell crank that is pivotally supported in advance with respect to the base plate pivotally supports the base end of a rocking control rod having a knob at the tip and pivotally supports the lock device. A ring shape in which the base end side of the rod is also pivotally supported on the opposite side, and the shank part of the locking control rod is loosely inserted into the curling of the end of the arm attached to one end of the base plate or the clamp or clip that is attached with one touch. While allowing a vertical movement and a slight lateral displacement through the gap, it is possible to maintain a predetermined posture with respect to the bell crank and the base plate at all times so that the door trim is mounted on the door and the door is locked. The assembly work to face the knob of the assembly to the hole of the door trim does not require any skill and is smooth and accurate. It is something that can be done.

<Embodiment> An embodiment of the present invention will be described below with reference to FIGS. It should be noted that parts that are the same as those in the drawings starting from FIG. 6 will be described using the same reference numerals.

In the embodiment shown in FIGS. 1 and 2, reference numeral 1'denotes a door locking assembly that forms the center of the invention, and its bell crank 4 has an inner panel 11 of a door 10 similar to the general embodiment shown in FIG. It is rotatably supported by a pin 3 on a base plate 2 which is attached to the base plate 2 with a screw 25, and the base end of a locking control rod 6 having a knob 5 at the tip is snapped to one end of the bell crank 4. The rod 8 is rotatably supported via 7 ', and the other end of the rod 8 is rotatably supported via a snap 9'on the base end of a rod 8 which is connected to a locking device (not shown). Reference numeral 16 denotes an arm as a holder, which is formed integrally with the base plate 2 when the base plate 2 is formed and laterally extended, and a tip end portion of the curling portion 17 has a diameter larger than the diameter of the locking control rod 6 by a set amount. Is formed so that the shank portion of the locking control rod 6 is loosely inserted.

In this embodiment, as shown in FIG. 1, when the locking control rod 6 is moved up and down by pulling out and pushing in the knob 5 of the door locking assembly 1'in the assembled state. Since the snap 7'on the base end side is relatively moved by e with respect to the long groove direction of the bell crank 4, it is displaced by a slight distance f also in the lateral direction. 17
The inner diameter of the rocking control rod 6 should be a diameter that has a plus α clearance allowed for the lateral movement amount f in addition to the diameter of the rocking control rod 6, and therefore the shorter the raising / lowering stroke of the rocking control rod 6 is, the shorter. The inner diameter of the curling portion 17 of the holder 16 can be made smaller, so that the amount of tilting of the locking control rod 6 can be made extremely small, if not zero,
It is designed to guarantee the accuracy and smoothness of the assembly work.

In the above-mentioned structure, the door locking assembly 1'is provided, and as shown in FIG.
When the door locking assembly 1'is installed in a predetermined position of 11 and the knob 5 is exposed to the retractable hole 13 when the door trim 14 is installed, the door locking assembly 1'has its pre-installed attitude predetermined through the friction of each mechanism portion. Even if the knob 5 and the rocking control rod 6 are erected in order to maintain them, only a slight lateral displacement f occurs, so that the assembling work is hindered and the collapse which causes obstacles is prevented. Since it hardly occurs, therefore, it is not necessary to adjust the lateral position of the door trim 14 unnecessarily, and it is difficult for a general worker to smoothly assemble and predeterminedly attach the knob 5 to the retractable hole 13 without requiring skill. Done without. Thus, when the knob 5 is pushed in and lifted after the assembling, the snap 7'at the base end of the knob 5 is surely locked and unlocked by a slight displacement f with respect to the elongated hole of the bell crank 4. Locking action is performed.

Next, the embodiment shown in FIGS. 3 and 4 is a mode in which the holder 16 'is composed of an arm and a clip attached to the tip of the arm with one touch, and the relative behavior of the shank of the locking control rod 6 is inside the clip. The allowable gap is formed, and there is no difference in its function and effect from the above-mentioned embodiment.

The embodiment shown in FIG. 5 is a mode in which a one-touch clamp 16 ″ is engaged with the arm by one-touch instead of the clip 16 ′ of the above-mentioned embodiment, and the shank portion of the locking control rod 6 is also provided at the tip thereof. The minimum gap is formed so as to share the same relative to each other, and the same operational effect as each of the above-described embodiments is exhibited.

Needless to say, the embodiment of the present invention is not limited to the above-mentioned embodiments. For the holder, the hook extending from the bell crank side is formed with a notch or the like along the longitudinal direction on the side surface of the locking control rod. , Various modes such as relatively slidable engagement can be adopted.

Further, it goes without saying that the application target can be applied to other parts than the rear door of the automobile.

<Effects of the Invention> As described above, according to the present invention, basically, in a door locking assembly provided in a rear door of an automobile or the like, the door is originally allowed to move up and down the locking control rod by pulling up and pushing the knob. While performing the locking function of the above, it is possible to assemble smoothly and accurately as designed without requiring any skill in assembling the inner panel of the door of the door locking assembly and the door panel of the door trim. That is an excellent effect.

And, since the holder for loosely inserting the locking control rod is previously attached to the base plate,
Assembling the locking control rod with knob to the door inner panel and the predetermined part of the door trim without causing the locking control rod to fall down, not only the effect that the assembly work can be performed smoothly and quickly, but also the door trim. Effects such as relatively large size and heavy weight are not moved with respect to the door locking assembly, assembly work is easier, work efficiency is improved, and there is no constraint on other lines. Is played.

Also, since it is only necessary to attach a holder to the base plate, it is possible to perform small processing work such as crushing the end of the locking control rod and base plate, or cutting and raising the claws and caulking at the end of the locking control rod as is done conventionally. Since it is not necessary to carry out the process, the number of steps is small, and not only the cost can be reduced, but also the processing management of these is not required.
