Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control handle device for remotely controlling a lock device of an automobile via a cable.

FIG. 1 shows an example of a conventional remote control handle device.

A handle 1 is pivotally mounted on a base plate 2 with a shaft 3 so as to rotate forward and backward by a predetermined angle α.
Reference numeral 4 denotes a spring for biasing the handle 1 to the neutral position, which is wound around the shaft 3, and after both extending ends sandwich the handle 1 from the front and back, the spring is attached to the shaft protruding from the base plate 2. Arc-shaped front and rear elongated holes 5 and 6 centered on 3
When the handle 1 is removed from the neutral position, the handle 1 is rotated to return to the neutral position.

One end of a cable 7 made of wire or the like is connected to the middle portion of the handle 1. The cable 7 is guided by a conduit 8 horizontally fixed to the base plate 2, and the other end is connected to, for example, a locking/unlocking lever of a door locking device.

In this handle device, a base plate 2 is fixed to the vehicle body near the driver's seat of a car, and by rotating the handle 1 forward to an angle α, a cable 7 guided in a conduit 8 is pulled by a distance l, and the door is locked. The device can be locked and the cable 7 can be moved a distance l by rotating the handle 1 backwards to an angle α.
The door lock device can be unlocked by pushing the door. (For example, see Japanese Patent Application Laid-Open No. 55-152277.) However, in such a conventional device, the connection point between the handle 1 and the cable 7 moves in a circle around the shaft 3 as the handle 1 rotates. In order to draw an arcuate trajectory, each time the handle 1 is rotated, the conduit 8
The more protruding ends of the cables swing up and down, causing strain on the cables 7 and causing a lack of smooth operation. If the cable 7 is bent, causing malfunction, or in severe cases, repeated bending of the cable 7 may cause the cable 7 to bend.
There are disadvantages such as breakage or cutting.

In order to eliminate this drawback, it is conceivable to increase the length of the handle 1 from the shaft 3 to the connecting part of the cable 7 so that the cable 7 traces a substantially linear trajectory. In this case, another drawback arises in that the entire device becomes larger.

The present invention was developed in view of the structural shortcomings of the conventional devices described above, and is designed to smoothly convert the force of the rotating handle into linear motion and transmit it to the cable. In addition, it is an object of the present invention to provide a remote control handle device that can operate smoothly and reliably by preventing the moving member from becoming stuck.

Hereinafter, the present invention will be explained in detail based on an embodiment shown in FIGS. 2 to 4.

Reference numeral 11 denotes a board, which includes a horizontal base 11a, side pieces 11b standing up from both sides of the base 11a, and mounting pieces 11 extending horizontally from both sides of the base 11a.
It consists of c. Base 11a and mounting piece 11c
Screw holes 12 are drilled at appropriate locations in the substrate 11 so that the board 11 can be fixed at appropriate locations on the body of the automobile with appropriate setscrews (not shown). Further, a rectangular opening 11d is bored in the center of the base 11a.

In the lower part between the both side pieces 11b of the board 11,
The lower end of a handle 14, which has a dogleg-shaped side surface and has a handle 13 at its upper end, is pivoted about a shaft 15 in the left-right direction.

In addition, a pinion 16 that expands upward into a fan shape is pivotally attached to the center of the shaft 15 so as to be fixed or engaged with the handle 14 so that it can rotate integrally with the handle 14. There is.

A shaft 1 in the left-right direction is mounted on both sides 11b of the base plate 11 at a required distance from the upper end of the pinion 16.
7, a roller 18 is pivotally mounted, and between the roller 18 and the pinion 16 there is a rack 19 provided with teeth 19a that mesh with the teeth 16a of the pinion 16.
is clamped so as to be movable in the tangential direction of the pinion 16.

The positional relationship between the rack 19 and the handle 14 is such that when the handle 14 is in the neutral position facing vertically, the rack 19
The center part of the handle 14 engages with the pinion 16.
as shown by the imaginary line in Figure 4, in the front-back direction (fourth
By tilting it in the horizontal direction (in the figure),
The relationship is such that the rack 19 moves forward and backward in a straight line in the tangential direction of the pinion 16.

At the center of the roller 18, there is a chevron-shaped annular protrusion 18a.
is formed, and this annular protrusion 18a is connected to the rack 19.
V-shaped groove 19b cut in the longitudinal direction of the back surface of
By engaging with the rack 19, movement of the rack 19 in the left and right direction is prevented.

In this embodiment, the rack 19 is inclined so that its rear end (the right end in FIG. 4) faces slightly downward, and two parallel rods 20 are connected to the rear end of the rack 19.

Both rods 20 protrude into a case 21 that is supported at a suitable position on the vehicle body so as to be located on an extension line of the rack 19. Inside this case 21, the rear ends of both rods 20 are connected to a connecting member that also serves as a slider. 22, one ends of the cables 23 are connected to each other.

Each cable 23 is made of a flexible material such as a hard steel wire, and is guided by a flexible conduit 24 fixed to the rear end of the case 21, and the other end is connected to the object to be operated. has been done.

FIG. 5 shows the arrangement of the device of the present invention having the above-mentioned structure when it is actually installed in a car. The cable 23 is fixed at a suitable location on the vehicle body, and one cable 23 is introduced into the right rear door 27 through the door hinge part, and the free end of the cable 23 is connected to the door lock device 28 of the door 27. The other cable 23 is connected to the lock/unlock lever (not shown) in the left rear door 2.
The cable 23 is introduced into the door 29 through the door hinge section 9, and the free end of the cable 23 is connected to a lock/unlock lever (not shown) in a door lock device 30 of the door 29.

As is well known, when the lock/unlock levers in the door lock devices 28 and 30 are set to the locked position, the door lock device is locked, and the door lock device cannot be unlocked even if the door handles inside and outside the vehicle are operated. In addition, by setting the door lock device to the locked position, the door lock device is placed in an unlocked state, and the door lock can be released by operating a door handle inside or outside the vehicle, allowing the door to be opened.

Thus, in the embodiment described above, by tilting the handle 14 forward from the neutral position, the pinion 16 is rotated counterclockwise in FIG. 4, and the rack 19 is advanced in the tangential direction of the pinion 16. By pulling the cable 23 through the rod 20, the locking/unlocking levers of the door locking devices 28, 30 can be switched, for example, to the locked position.

Also, by tilting the handle 14 backward from the neutral position, the pinion 16 is rotated clockwise in FIG.
6 in the tangential direction, the cable 23 can be pushed via the rod 20, and the locking/unlocking levers of the door locking devices 28, 30 can be switched, for example, to the locked position.

In this embodiment, at this time, the right end of the pinion 16 in FIG.

When the handle 14 is in the neutral position, each door lock device 2 is locked by operating a lock/unlock knob (not shown) protruding from the window frame of each rear door 27, 29.
It is preferable that the lock/unlock levers 8 and 30 can be operated independently. For this purpose, the end of each cable 23 on the door lock side and each locking/unlocking lever may be connected with the required play, but such a configuration is not directly related to the present invention. Illustrations and detailed explanations thereof will be omitted.

Further, in the above embodiment, the handle 14
The handle 14 can be stopped and held at a desired position by a spring (not shown) provided between the lock lever and each lock/unlock lever, but if necessary, a spring similar to the spring 4 shown in FIG. 1 may be used. The handle 14 may be always biased toward the neutral position by this spring.

As is clear from the above, in this invention,
The rotating motion of the handle is converted into linear motion by the pinion and rack structure to operate the cable, so there is no stress on the cable and operation is performed smoothly. Since there is no risk of bending of the cable, there are advantages such as there is no risk of malfunction or breakage of the cable.

In addition, the range of linear motion of the cable can be determined only by the length of the contact surface between the pinion and the rack, so unlike conventional devices in which the cable is connected directly to the handle, there is no need to increase the size of the device. However, it also has the advantage of being able to perform a variety of remote operations using cables and having a simple configuration.

Further, in the present invention, by making the distance between the pinion and the roller slightly larger than the actual thickness of the rack, the rack can operate smoothly even if the inclination angle of the rack is slightly deviated.
Therefore, there is a slight degree of freedom in the angle of inclination, and there is no need to set precise positions for mounting the substrate and rack support members (case 21, etc. in the above embodiment), which makes the mounting work easier. There are also some effects.

Furthermore, in the present invention, the engagement between the annular protrusion formed on the roller and the groove formed on the rack prevents the rack from moving laterally.
The rack moves sideways and touches the board,
It is possible to prevent the rack from moving unsmoothly, or from causing the so-called "biting" or "sticking" phenomenon on the board, etc., resulting in the rack becoming unable to move. In addition to the degree of freedom in the angle of inclination, the smoothness and reliability of operation can be improved.

The above-mentioned embodiment has been described as a handle device for remote control of a lock/unlock lever in a car door lock device, but the present invention is not limited to this embodiment, and can be used to operate other objects to be operated. Needless to say, the present invention is also applicable to a handle device.
