Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device capable of holding various operating levers in a door lock device of an automobile or the like at a desired fixed position.

Operation levers such as locking levers and knob levers in automobile door locking devices can be switched to a plurality of switching positions such as a locked position and an unlocked position by operating a locking/unlocking knob or a key plate.

This type of operating lever may have moved inadvertently between the switching positions due to vibrations of the vehicle, etc.
Since the door lock may malfunction, means are required to hold each operating lever in each switching position.

As shown in FIG. 1, a conventional holding means of this type uses an over-center type coil spring.

To explain Fig. 1, door lock device a
A locking/unlocking lever d is pivotally connected with a shaft c to the center of the lower part of a substrate b fixed to one side of the main body (not shown). position and a locked position shown in phantom lines in FIG.

In order to stably hold this lock/unlock lever d in the unlocked position and the locked position, one leg f of the overcenter type coil spring e is placed on the board b side, and the other leg g is The other leg g is locked to the lock lever d side, and the other leg g is connected to the one leg f.
The biasing direction of the lock/unlock lever d is reversed each time the lock/unlock lever d passes over a line segment l passing through the center of the axis c and the center of the axis c.

However, in the case where such an over-center type coil spring is used, the spring is inserted into a narrow gap between the board and the control lever, and both legs of the spring are inserted into the respective mounting holes of the board and the control lever. They must be locked manually, making the assembly process extremely troublesome and difficult. Depending on the length of the legs, there is a risk that the legs may break or fall off. Since the shapes of some springs are similar, there are drawbacks such as the risk of incorrect assembly.

The present invention focuses on the fact that the main body of a door lock device for automobiles, etc. is usually made of a synthetic resin material with appropriate elasticity. It is an object of the present invention to provide a fixed position holding device for an operating lever in a door lock device for an automobile, etc., which can hold the lever in a desired fixed position and thereby eliminate the above-mentioned drawbacks.

The present invention will be explained below based on the embodiment shown in FIGS. 2 and 3.

1 is a thin box-shaped body made of a hard synthetic resin material with appropriate elasticity, such as acetal resin, and its interior includes a latch that engages and disengages a striker on the vehicle body, and a state in which the latch is engaged with the striker. A locking plate, etc. (all not shown) for locking the door is provided, and the opening surface is closed with an appropriate closing plate (not shown), and then attached to the inner surface of the end plate of the door. It can be done.

A substrate 2 for pivotally mounting various operating levers is fixed to the surface of the main body 1 opposite to the closing plate.

At the center of the lower part of the base plate 2, a locking/unlocking lever 3, which constitutes one operating lever, is pivoted at a substantially central portion thereof with a shaft 4.

The right end of the lock/unlock lever 3 in FIG. 2 is connected to a key cylinder device (not shown) via an appropriate rod (not shown), and the left end of the lock/unlock lever 3 in FIG. 2 is connected to another operating lever. The door is connected to a locking/unlocking knob (not shown) provided on the inside of the vehicle through a knob lever (not shown) that forms a door, and can be locked/unlocked by operating this knob or key plate (not shown). The lever 3 can be switched between an unlocked position shown in solid lines in FIG. 2 and a locked position shown in phantom lines in FIG.

When the locking/unlocking lever 3 is in the unlocking position, the sub-lever 6, which is connected to the protruding piece 3a projecting from the upper center of the locking/unlocking lever 3 through a substantially vertically elongated hole 5, is shown in FIG. in the unlocked position as shown. In this state, by operating the outside handle or inside handle (both not shown) of the door, the sub-lever 6 is pushed downward, and the protruding piece 6a of the sub-lever 6 is used to move the first protruding piece 7a of the open lever 7. The door can be opened by rotating the striker clockwise in FIG. 2 to disengage the latch provided in the main body 1 and the striker.

When the lock/unlock lever 3 is in the locked position, the sub-lever 6 is also moved in conjunction with the lock/unlock lever 3 from the unlocked position shown in FIG. It is located at a locked position (not shown) that is off to the right from the movement trajectory. In this state,
Even if the sub-lever 6 is pushed downward by operating the outside handle or the inside handle, the protrusion 6a simply swings against the first arm 7a of the open lever 7, and the open lever 7 cannot be rotated. You will not be able to open the door.

The above structure is the same as that of a known door lock device, and the present invention is characterized by adding the following structure to the above structure.

That is, a protruding shaft 8 facing toward the main body 1 is located between the left end of the locking/unlocking lever 3 in FIG. 2 and the pivot portion.
At the same time, a hanging piece 9 is extended from the lower end of the main body 1 near the board 2, and the lower end of the hanging piece 9 is shaped like a hook toward the left in FIG. 2 while gradually narrowing the width. The elastic bending piece 10 is curved, and an elastic bending piece 10 facing upward and having a substantially arc shape centered on the shaft 4 is integrally connected to the tip thereof.
By pressing the left side edge 10a of the elastic bending piece 10 against the right side surface of the protruding shaft 8, the protruding shaft 8 rotates while slidingly contacting the left side edge 10a of the elastic bending piece 10 as the lock/unlock lever 3 rotates. It is set as.

The left side edge 10a of this elastic bending piece 10 has a recess 11 that engages with the protruding shaft 8 when the lock/unlock lever 3 is in the locked position, and a recess 11 that engages with the protruding shaft 8 when the lock/unlock lever 3 is in the unlocked position. Concave portions 12 that engage the protruding shaft 8 are formed in two stages, upper and lower, and a peak portion 13 is formed in the middle of both the concave portions 11 and 12.

Further, at the upper end of the elastic bending piece 10, a leg piece 14 facing right in FIG. On the other hand, the inclined surface 14a, which is inclined to the contrary, is always in contact with the tip of a protrusion 15 that is connected to the middle part of the hanging piece 9 and faces leftward in FIG.

This leg piece 14 is for supporting the elastic bending piece 10 at two points, an upper end and a lower end.

That is, without this leg piece 14, when the protruding shaft 8 climbs over the mountain part 13, the entire elastic bending piece 10
Using the lower end, which is the connecting part with the hanging piece 9, as a fulcrum,
There is a risk of bending greatly to the right in FIG.
There is a possibility that an imbalance may occur in the pressing force applied to the protruding shaft 8 depending on the case where the protruding shaft 8 is engaged with the protruding shaft 8. However, by providing the leg piece 14 and supporting the elastic bending piece 10 at two points, upper and lower, it is possible to prevent the risk of breakage and permanent deformation as described above, and to reduce the pressure contact force against the protruding shaft 8 almost as much. It is possible to make it uniform.

In addition, when a large load is applied to the upper end of the elastic bending piece 10, the leg piece 14 itself also elastically deforms and rides on the tip of the protrusion 15.

In the above-mentioned embodiment, the lock/unlock lever 3 is
The protruding shaft 8 is located in one of the recesses 11 of the elastic bending piece 10,
12, it is stably held in either the locked position or the unlocked position, and does not move accidentally due to vibrations or the like.

In addition, by rotating the locking/unlocking lever 3 with the necessary force for the protruding shaft 8 to overcome the peak 13, it is possible to provide an appropriate resistance force to the rotational operation of the locking/unlocking lever 3. can.

As is clear from the above, according to the present invention, the protruding shaft is protruded from the operating lever and the elastic bending piece is integrally molded with the main body, which makes it easy to manufacture and requires no special assembly work. It is possible to provide an extremely convenient device for holding a control lever in a fixed position in a door lock device for an automobile, etc., which can reliably hold the control lever in a desired fixed position without any need for the control lever.
Further, according to the present invention, an elastic bending piece is integrally connected to the tip of a part of the main body curved into a hook shape, and an inclined surface of a leg piece connected to the tip of the elastic bending piece. Press it against the tip of the protrusion provided on the main body,
When a large load is applied to the elastic bending piece, the leg piece rides on the tip of the protrusion, so that the following functions and effects can be achieved.

(a) Since the hook-shaped curved portion of the main body is elastically deformed when the elastic bending piece is elastically bent, the risk of breakage of the elastic bending piece is reduced.

(b) When the elastic bending piece is supported by the main body at two points, the base and the tip of the leg, as the leg comes into pressure contact with the tip of the protrusion, the elastic bending piece is supported in a cantilever manner. In addition to preventing the risk of breakage and permanent deformation as in
It can be almost uniform.

(c) When a large load is applied to the elastic bending piece,
By the leg pieces riding on the tips of the protrusions, it is possible to absorb impact and prevent the elastic bending pieces and the leg pieces from breaking.

In addition, although the above-mentioned embodiment is a case where the present invention is applied to a holding device for a lock/unlock lever, the present invention can also be applied to a holding device for a knob lever or other operating lever.

Further, in the above embodiment, two recesses corresponding to the locking and unlocking positions of the locking/unlocking lever are formed on one side edge of the elastic flexible piece, but the It is also possible to have three or more recesses depending on the number of switching positions.
