It is widely used in automobiles.

This type of operating device is designed so that the inside handle is rotated by a predetermined angle to actuate the operating rod by a predetermined stroke corresponding thereto, and at this time, the locked state of the door lock device can be released. However, in an actual operating device, when the inside handle is rotated, the actuating rod is bent.Therefore, the locked state of the locking device cannot be released unless the inside handle is rotated more than the designed angle. There is. If such a situation occurs, it is inevitable that the operator feels uncomfortable and the operation feeling deteriorates. Deflection of the actuating rod is particularly likely to occur when a portion of the rod is bent or curved.

OBJECT It is an object of the present invention to provide an operating device for a door lock device which eliminates the above-mentioned conventional drawbacks.

In order to achieve the above object, the present invention provides an operating device of the type described at the beginning, in which the operating rod is biased in a direction that prevents the rod from bending when the inside handle is operated to pull the operating rod. A configuration is proposed in which a spring is provided between the actuating rod and the inner panel of the door.

Similarly, the present invention relates to an operating device of the type described at the beginning, which is attached to an inner panel of a door and has a guide plate formed with a long hole extending in a longitudinal direction, and is fitted to the operating rod, and the guide plate. In the long hole of the plate,
The sliding member is slidably fitted in the longitudinal direction, the anchor attached to the guide plate and the sliding member are engaged, and when the inside handle is operated to pull the operating rod, It is proposed to provide a biasing means including a spring that biases the actuating rod in a direction that prevents the rod from bending.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings, and the above-mentioned conventional drawbacks will be more specifically clarified with reference to the drawings.

FIG. 1 is a schematic front view showing a state in which a door of a car is viewed from the inside of the car. The door 1 shown here has an inner panel 2 on the inner side of the vehicle and an outer panel 12 on the outer side of the vehicle, and a door trim is further provided on the inner side surface of the inner panel 2, but this trim is omitted in the figure. . Arrow X indicates the forward direction of the vehicle.

A door lock device 8 is provided between the inner panel 2 and the outer panel 12 of the door 1, and the lock device 8 is operated by its operating device. As shown in FIG. 2, the operating device for the door lock device is pivotally supported by a bezel 3 fixed to the inner panel 2 of the door 1 and a pivot pin 5 on the bezel 3. It has an inside handle 4 which is operated from the inside of the vehicle and an operating rod 6 which transmits the operation of the handle 4 to the door lock device 8. The operating rod 6 is locked to the rear end of the inside handle 4, the rod 6 extends rearward along the inner panel surface, and the rod 6 extends between the inner panel 2 and the outer panel 12 through a hole 7 formed in the panel 2. It projects into a space and is connected to a lever 9 of a door lock device 8 arranged in the space.
A part of the actuating rod 6 is bent as indicated by reference numeral 6a in FIG. 1, which will be described later.

When the door 1 is closed and the door lock device 8 is in the locked state in which the door 1 is locked, the inside handle 4 occupies the initial position shown by the solid line in FIG. 2, and the operating rod 6 is also in the positions shown in FIGS. 1 and 2. It has stopped at the initial position indicated by the solid line.

When the inside handle 4 is gripped from the inside of the vehicle and rotated by a predetermined angle θ as shown by the chain line in FIG. 2, the operating rod 6 is pulled forward, and the front end of the rod 6 moves in the stroke indicated by a. When actuated, the rod 6 moves substantially parallel to the position shown by the alternate long and short dash line in FIG. In this way, the operation of the inside handle 4 is transmitted to the door lock device 8 via the operating rod 6, and the lever 9 thereof is rotated as shown by the alternate long and short dash line. As a result, other elements (not shown) of the locking device 8 are activated, the locked state is released, and the door 1 can be opened. Assuming that the movement stroke of the rear end of the operating rod at this time is b, this stroke b and the aforementioned stroke a are normally set to be equal.

Here, in addition to the above-mentioned elements, the operating device in this example is provided with a biasing means 11 provided with a tension spring 10 for biasing the operating rod 6, as shown in FIG. Before describing the details of the urging means 11, the drawbacks of the conventional operating device without such means will be specifically clarified.

FIG. 6 is a front view of a door having a conventional operating device,
The only difference from FIG. 1 is that the above-mentioned biasing means is not provided. Therefore, this operating device is also configured so that the locked state of the door lock device 8 can be released by rotating the inside handle 4 and operating the operating rod 6 at the initial position indicated by the solid line to the position shown by the alternate long and short dash line. There is. That is, the front end of the operating rod 6 is moved forward by the stroke indicated by a and the rear end thereof is moved by b.
The door lock device 8 is designed to be unlocked by moving (= a).

However, since the operating rod 6 is made of, for example, a small diameter iron wire having a diameter of about 3.5 mm, when the front end of the operating rod 6 is actually operated, the rod 6 is shown by a chain double-dashed line in FIG. Flex like. Such deflection is caused by the operating rod 6
Is likely to occur when a part of it is bent or curved as indicated by reference numeral 6a. That is, the operating rod 6 is the bent portion.
It is elastically deformed to open around 6a. In any case, when such a deflection occurs, even if the front end of the operating rod 6 is operated by the stroke a, the movement is eaten by the deflection of the operating rod 6, and the rear end does not operate the predetermined stroke b. . Therefore, the operator pivotally operates the inside handle 4 at an angle larger than the designed value shown by θ in FIG. 2, and the front end of the operating rod 6 is moved up to the position shown by the chain double-dashed line in FIG. That is, the locked state of the door lock device 8 cannot be released unless the large stroke indicated by c is operated. If the lock can be released only by rotating the inside handle 4 by a large angle in this way, the operator feels uncomfortable and the operation feeling deteriorates.

If the operating stroke b at the rear end of the operating rod until the door lock device 8 is unlocked is set to be small, the operating stroke at the front end of the operating rod until the lock is released can be reduced even if the operating rod 6 bends. Although the above-mentioned inconvenience can be eliminated, the stroke b cannot be made so small due to various requirements imposed on the door lock device 8, and the above-mentioned solution cannot be adopted.

Therefore, the operating device in this example is provided with the biasing means 11 provided with the tension spring 10 as described above, and the spring 10 prevents the actuation rod 6 from bending.

As shown in FIGS. 1 and 3, the urging means 11 is attached to the inner panel 2 of the door 1 via a pin 14 and has a guide plate 15 having a long hole 17 extending in the longitudinal direction.
A guide plate is fitted at a proper position of the operating rod 6, preferably at the bent portion 6a of the rod 6 or in the vicinity thereof.
An anchor 16 attached to the plate 15 has a sliding member 13 slidably fitted in the elongated hole 17 of the plate 15 in the longitudinal direction thereof.
Each end of the tension spring 10 is locked to the above-mentioned sliding member 13. In this way, the tension spring 10 is provided between the operating rod 6 and the inner panel 2 of the door 1 via the sliding member 13 and the guide plate 15, respectively.
The sliding member 13 is slidably fitted to the operating rod 6 to which the sliding member 13 is attached.

The tension spring 10 extends in a direction perpendicular to the actuating rod portion to which the sliding member 13 is attached, that is, in the direction indicated by reference numeral Y in FIG. The elongated hole 17 formed in the guide plate 15 also extends in the same direction Y, and the lower portion 18 of the sliding member 13 is slidably fitted in the elongated hole 17.

Due to the spring 10 described above, the actuating rod 6 is always
Receives a force P in the extending direction. Therefore, as described above, by rotating the inside handle 4 from the initial position shown by the solid line in FIG. 2 to the position shown by the alternate long and short dash line, the operating rod 6 is pulled forward and the rod 6 is moved to the first position. When moving from the initial position indicated by the solid line in the figure to the position indicated by the alternate long and short dash line substantially in parallel, the actuating rod 6 is urged by the force P by the tension spring 10. That is, the tension spring 10 attaches the operating rod 6 in a direction that prevents the rod 6 from bending as shown by the chain double-dashed line in FIG. 6 when the operating handle 6 is pulled by operating the inside handle 4. Energizing and operating rod 6
It prevents the flexure. In this way, even if a part of the actuating rod 6 is bent or curved as indicated by reference numeral 6a, it is possible to prevent the actuating rod 6 from largely bending during its operation.

When the operating rod 6 is operated, the sliding member 13 moves to the guide plate 15
Since the sliding member 13 slides in the long hole 17 of the sliding member 13 and the sliding member 13 relatively slides with respect to the operating rod 6, the sliding member 13 does not hinder the movement of the operating rod 6. The action of the spring 10 can always be applied to the actuating rod 6.

As described above, when the operating handle 6 is pulled by operating the inside handle 4, the operating rod 6 is pulled by the tension spring 10.
In order to prevent the bending, the actuating rod 6 moves from the initial position shown by the solid line in FIG. 1 to the position of the alternate long and short dash line while drawing a predetermined trajectory as designed. Therefore, simply actuating the front end of the operating rod 6 with the stroke a as designed,
The rear end of the rod 6 is operated by a predetermined stroke b,
The locked state of the door lock device 8 can be released. In other words, the inside handle 4 can be unlocked by rotating the inside handle 4 by the predetermined angle θ shown in FIG. 2, thereby preventing the operator from feeling uncomfortable.

When the inside handle 4 is operated to move the operating rod 6 to the position indicated by the alternate long and short dash line, and then the hand is released from the handle 4,
These must be returned to the initial position shown by the solid line. Therefore, conventionally, the pivot pin 5 of the inside handle 4 is
A torsion coil spring is provided around (FIG. 2) so that when the inside handle 4 is released, the handle 4 and the operating rod 6 are returned to their initial positions by the force of this spring. However, since the tension spring 10 is provided in this example, the inside handle 4 and the operating rod 6 can be returned to the initial position by the spring 10. That is, the spring 10 prevents the actuation rod 6 from bending and
Also, it does not function as a return spring for returning the inside handle 4 to the initial position, and thus it becomes possible to omit the torsion coil spring which has always been required.

In the illustrated example, the arrows R and S are shown in FIGS.
As shown by, the guide plate 15 is swingably supported on the inner panel 2 around the pin 14, and the sliding member 13 is also swingably supported on the guide plate 15. Therefore, when the operating rod 6 operates between the position shown by the solid line in FIG. 1 and the position shown by the alternate long and short dash line, the direction (angle state) of the operating rod portion to which the sliding member 13 is attached varies. However, the sliding member 13 and the guide plate 15 oscillate, that is, oscillate their heads in response to this variation. As a result, there is no problem that the biasing means 11 interferes with the movement of the operating rod 6.

In the above embodiment, the tension spring 10 is used as the spring for biasing the rod 6 in the direction in which the deflection of the actuation rod 6 is prevented, but various springs other than the tension spring may be used if the same purpose can be achieved. For example, as shown in FIG. 5, at a position opposite to the tension spring 10 shown in FIGS. 1 and 2,
A compression spring 100 locked to the anchor attached to the guide plate 15 and the sliding member 13 may be provided so that the force P is applied to the operating rod 6. Of course, it is possible to use both the compression spring 100 and the tension spring 10.

The present invention can be advantageously applied not only to a case where a part of the actuating rod is bent but also to a bending operation device.

Advantageous Effects of Invention According to the operating device described in claims 1 and 2, the actuating rod is prevented from bending by a very simple structure in which a spring is provided, and the inside handle is rotated by a predetermined angle to lock the locking device. Can be released. Therefore, it is possible to prevent the operator from feeling uncomfortable and to improve the operation feeling.
