Description

[Detailed description of the invention] [Technical field of the invention] The invention relates to an operating device for a temperature control shutter,
In particular, the present invention relates to the operating device installed on the front panel of an automobile.

[Prior Art] Conventional operating devices for temperature control shutters installed in automobiles generally include an operating lever a rotatably mounted via a support shaft b, as shown in FIG. A knob c extends from a groove e in a front panel part d, and an operating cable or rod f leading to a temperature control shutter is secured to the other end.

However, in the case of the above-mentioned operating device, since the operating knob c draws an arc-shaped rotation locus centered on the support shaft b, there is a drawback that the installation space becomes large, and the operating position of the operating lever a is As a result, the amount of protrusion into the room changes, resulting in not only poor operability and danger, but also an undesirable appearance.

[Problem to be solved by the invention] In order to solve the problem of the operating knob c of the operating device not having an arcuate rotation trajectory, an elongated hole is provided in the pivot portion of the operating lever a as shown in FIG. An operating device in which the arc-shaped rotation locus is eliminated has been proposed, but the operating cable side end of the operating lever a is pushed out, which necessitates an increase in internal installation space.

On the other hand, Utility Model Application No. 55-151611 and Utility Model Application No. 59-
Publication No. 1609 also proposes an operating device to solve the problem caused by the arc-shaped rotation locus of the operating knob as described above, but in the former proposal, a long hole is formed in the main link. However, since the arc-shaped rotation locus is eliminated, the end of the control lever on the operating cable side is pushed out, which may result in an increase in internal installation space. A large depth is required to allow the branch to rotate to the dead center, which may lead to an increase in the size of the device.

In addition, in the latter proposal, the base end of the driven lever needs to be deep enough to rotate the pivot part to the dead center, which may lead to an increase in the size of the device. .

The present invention was devised to eliminate the drawbacks of the above-mentioned prior art, and its purpose is to reduce the installation space and improve operability, appearance, and safety of the temperature control shutter. The goal is to provide equipment.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a guide member provided along the operation window of the case, and a guide member that is slidably fitted into the guide member and is arranged outside the operation window. a first link having a proximal end pivoted near one end of the guide member; one end pivoted to the operating lever and the other end pivoting to the first link; A second link is provided near the other end of the link, and a second link is provided near the other end for locking the operating cable of the temperature control shutter.

[Function] When the operating lever is slid along the guide member in the direction of pulling in the operating cable, the first link rotates about its base end as a fulcrum via the second link member, and the rotation The second
The operation cable is retracted by moving the link. When the operating lever is slid in the opposite direction from this state, the operating cable is let out.

In this way, the first link is pivoted near one end of the guide member, and the operating cable is operated by rotating the base end portion as a fulcrum and moving the second link in conjunction with the rotation. Therefore, unlike a device in which the intermediate portion or the base end portion of the operating lever is pivotally supported at the back of the device, it is possible to reduce the depth of the case.

[Embodiment] Hereinafter, an embodiment of the temperature control shutter operating device of the present invention will be described in detail with reference to the accompanying drawings.

3 to 5, reference numeral 1 is a case for mounting an operating device for a temperature control shutter installed on the front panel of an automobile, and this case 1 is formed into a box shape with an open top. A linear operation window 2 is formed in the. Also, case 1
Inside, a guide member 3 is installed in a straight line along the operation window 2.
The guide member 3 is provided with an operating lever 4 that is movable back and forth along its longitudinal direction. The guide member 3 consists of a guide rod that is stretched between both side walls of the case 1, and the operating lever 4 is fitted onto the guide rod so as to be able to move back and forth. The operating lever 4 has an operating knob 5 integrally extending through the operating window 2 in a direction perpendicular thereto.

Further, stopper grooves 6 are formed at appropriate intervals in the longitudinal direction at the front upper end of the case 1, and the stopper grooves 6 are formed at the upper part of the operating lever 4.
An engaging piece 7 made of a spring plate that engages with its own elastic force is provided.

Further, the other end of the engagement piece 7 is in sliding contact with the rear upper end of the case 1, and applies a frictional force to stop the operating lever 4.

On the lower part of the case 1 near one end of the guide member 3, a base end of a first link 9 whose free end rotates in a direction to pull in the operation cable 8 of the temperature adjustment shutter and the air adjustment shutter is supported. The first link 9 is rotatably supported via a shaft 10, and on the free end side of the first link 9 is a second link whose one end is rotatably supported via a support shaft 11 to the lower part of the operating lever 4. The other end of the link 12 is rotatably supported via a pin 13. That is, the movement of the operating lever 4 is transmitted to the first link 9 via the second link 12, and the first link 9 is configured to rotate in the direction in which the operating cable 8 is pulled in.

Therefore, the first link 9 is exclusively connected to the operating cable 8
It acts to guide the operating cable 8 in the retracting direction and to receive the reaction force generated when the operating cable 8 is retracted.

The operating cable 8 is locked onto the second link 12 near the free end of the first link 9.

Further, in this embodiment, the tip of the second link 12 is bent to extend as the first link 9 rotates in the direction of the guide member 3, and the tip of the second link 12 is bent to extend the tip. It is formed as a cable locking portion 14 that locks.

Further, a first link 9 whose base end is pivotally supported on the inner lower part of the case, and a first link whose one end is pivotally supported at the lower part of the operating lever 4 located upwardly away from the inner lower part of the case 1. In order to connect the link 12 of 2,
The free end sides of each are bent upward and connected as shown in FIG. 5, and gap adjustment members such as bushes are omitted to reduce the number of parts.

Next, the operation of the embodiment of the present invention will be described.

In FIG. 4, when the knob 5 is pushed to the right, the operating lever 4 moves along the guide member 3, and the force is transmitted to the first link 9 via the second link 12. The first link 9 is rotated clockwise around the support shaft 10 at the base end. At this time, the cable locking portion 14 formed on the second link 12 moves along the rotation locus of the first link 9 and pulls in the operating cable 8. In particular, as in the embodiment, the cable locking part 14 is bent and formed at the tip of the second link 12 so that the tip extends as the first link 9 rotates in the direction of the guide member 3. Therefore, the length of the first link 9 can be shortened, and the device can be made smaller. Cable locking part 1 by pulling in the cable
The reaction force acting on the case 4 is transmitted to the case 1 via the first link 9, and the second link 12,
The signal is transmitted to the case 1 via the operating lever 4 and the engaging piece 7, and the operating lever 4 can be reliably fixed at the desired operating position, and the operating lever 4 can be automatically moved by the reaction force of the cable. There is no such thing as moving.

On the other hand, if the knob 5 is pushed to the left, the first
The link 9 rotates counterclockwise to let out the operating cable 8.

Since the operating lever 4 can be moved and operated in a straight line along the guide member 3, the knob 5, which is the operating end, does not protrude into the vehicle depending on the operating position. The performance, appearance and safety can be improved as much as possible.

In addition to the fact that the operating lever 4 is of the sliding type as described above, the base end of the first link 9 is pivoted near one end of the guide member 3, and the free end thereof is connected to the operating cable. Since the lever 8 is rotated in the retracting direction, the installation space can be reduced, unlike the conventional operating device in which the longitudinal center portion of the operating lever is pivoted.

[Effects of the invention] As described above, the operating device for a temperature control shutter of the present invention includes a guide member provided along the operation window of the case, and a guide member that is slidably fitted into the guide member and is provided outside the operation window. a first link having a proximal end pivoted near one end of the guide member; one end pivoted to the operating lever and the other end pivoting to the first link; A second link is provided near the other end to lock the operation cable of the temperature control shutter, so that the operation lever can be aligned in a straight line along the guide member. The first link can be moved, and its operating end does not protrude into the vehicle interior depending on the operating position, improving operability, appearance, and safety. Since the operation cable is operated by rotating the base end pivoted near one end of the guide member on the operation window side as a fulcrum and moving the second link with the rotation, the depth of the case is This has the effect of making the operating device smaller and lighter.
