Description

[Detailed Description of the Invention] The present invention relates to a device for operating vehicle equipment such as a heater for heating a vehicle interior, and particularly relates to an improvement of an operating device equipped with a rotary operating lever.

Since vehicle operating devices are installed in a limited space, they must be as compact as possible, and can be operated easily, nimblely, and without fear of erroneous operation while driving. This is required.

On the other hand, as requirements for vehicle comfort, safety, etc. become more sophisticated, an operating device that can take on a large number of operating states has become necessary.

For example, a heater for heating a car interior has three modes: a heat mode in which warm air is blown out only from the first outlet, a vent mode in which warm air is blown out only in the second outlet, a pie level mode in which warm air is blown out from both the second and second outlets, and a heat mode in which warm air is blown out only from the second outlet. Normally, it can be switched to four modes, including a defroster mode in which the air blows out from the mouth.

For this reason, the heater outlet switching device has generally been configured so that the control lever can be rotated to a total of four positions: two positions at both ends and two positions in the middle.

However, as mentioned above, due to limited space, the rotation range of the operating lever is relatively narrow, and as a result, it is difficult to rotate the operating lever from one operating position to an adjacent operating position with sufficient precision. It was difficult.

If an attempt is made to operate the outlet switching damper with a small amount of rotation, the required operating force will inevitably increase and the operability will inevitably deteriorate.

Furthermore, if the operating positions are close to each other, the operation of the operating lever becomes delicate, increasing the possibility of erroneous operation.

On the other hand, in Utility Model Publication No. 52-37396, (a
) a base; (b) a lever rotatably attached to the base by a pivot; and (C) a lever having a longitudinal shape, which rotates integrally with the lever and moves relative to the lever in the longitudinal direction. An operating device is described, which includes a possibly provided operating member.

This operating device can operate the target device into three or more states by both rotating the operating member and moving the operating member in the longitudinal direction. Since push-in positions can be used instead of positions, the number of rotation positions can be reduced.

However, on the other hand, since the operating member can be operated in two ways: a rotating operation and a pushing operation, the degree of freedom of movement of the operating member is too limited, and there is a risk of other erroneous operations.

With these circumstances in mind, the present invention has an operating member that can take a total of four positions: three rotational positions and one push-in position, and has an overall compact structure that provides excellent operability and eliminates the risk of erroneous operation. This was done with the aim of providing an operating device without any.

Feature 2 of the operating device according to the present invention is that, together with the (a) base body, (b) lever, and (c) operating member, (d) the operating member is provided with an angle perpendicular to the rotation plane of the operating member. (e) a pair of stopper surfaces located at both ends of a rotatable range of the projection around a pivot axis, and a regulating surface facing the projection from the pivot side; Both end portions of the regulating surface, which are fixedly installed and adjacent to each of the pair of stopper surfaces, are formed at positions spaced apart from the pivot by a certain distance compared to the central portion of the regulating surface, and the protrusions are located at positions adjacent to the pair of stopper surfaces of the regulating surface. In a state in which rotation is prevented by contacting one of the surfaces, the end portion of the restriction surface adjacent to the stopper surface contacts the protrusion, thereby preventing the operation member from being pushed toward the pivot side and preventing the operation member from being operated. and a regulating member that allows the operating member to be pushed a certain distance by allowing the central portion of the regulating surface to move toward the axis of the protrusion when the member is located at the center of the rotation range. be.

With this configuration, the operating member can be moved to a total of four positions: three rotational positions at both ends and the center of the rotation range, and one push-in position at the center pushed toward the pivot. , the operated device is operated into four operating states corresponding to these four positions.

The operated device may be connected only to the operating member, or may be connected to both the operating member and the lever separately.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings, taking as an example a case in which the present invention is applied to an operating device for an air outlet switching device of a heater.

In FIGS. 1 and 2, 1 is a base body, and an operating lever 2 and a driven lever 3 are attached to the base body 1 by a pivot shaft 4.

The operating lever 2 is a longitudinal operating member, and is mounted in an elongated hole 5 formed at its base end so as to be rotatable around a pivot 4 and also movable in the longitudinal direction.

The operating lever 2 protrudes outward through a slit 7 formed in a front member 6 fixed to the base body 1, and a knob 8 is attached to the protruding end thereof.

On the other hand, the driven lever 3 is mounted so as to be rotatable only around a pivot shaft 4, and the moderation spring 9 attached to the tip engages with the three grooves 11, 12, and 13 formed in the front member 6. It is designed so that it can be stopped with a sense of moderation at both end positions and an intermediate position.

The tip of the arm portion 14 extending from near the tip of the driven lever 3 in a substantially perpendicular direction is bent upward at a right angle to form an engaging portion 15. A slit 16 formed along the longitudinal direction of
It is being inserted into.

As a result, the operating lever 2 and the driven lever 3 can rotate integrally, and at the same time, only the operating lever 2 can move independently in the longitudinal direction.

This longitudinal movement limit is defined by the length of the elongated hole 5.

A pie level lever 17 is rotatably attached to the base 1 by a pivot 18.

The pie level lever 17 extends below the operating lever 2 in a direction substantially perpendicular to the operating lever 2, and has an elongated hole 2 that engages with a pin 21 fixed downward to the operating lever 2.
It is equipped with 2.

The elongated hole 22 has an arc shape that matches the trajectory drawn by the pin 21 when the operating lever 2 is pulled out and rotated as shown in FIG. Even if it is rotated, the pie level lever 17 is not affected by the rotation.

A bushing 23 in the shape of a cylindrical container with a flange is fitted to the lower end of the pin 21. When the pin 21 moves within the elongated hole 22, the bushing 23 rotates and the pin 21
This prevents local wear.

Note that the driven lever 3 is formed with an elongated hole 24 that allows the pin 21 and bush 23 to move.

The pin 21 is also engaged with a regulating member main body 25 provided integrally with the base body 1.

The regulating member main body 25 has a fan-shaped through hole 2 as shown in FIG.
6, and a flanged container member 27 of the same shape is press-fitted into the through hole 26 to constitute a regulating member together with the regulating member main body 25.
The lower ends of the protrusions cut out from the bushing 23 and the bushing 23 are fitted into the container-like member 27.

That is, the inner surface of the side wall of the container-shaped member 27 is formed by the bush 23.
pin 21 and bushing 23 in a state facing the entire outer peripheral surface of
The pivot portion 28 and the two guide surfaces 29 and 30, which are formed in a state that opens forward from the latch portion 28, which corresponds to the fan-shaped latch portion, surround the lower end portion of the pivot shaft 4.
The bush 23 faces the outer circumferential surface of the bush 23 from the side (more precisely, the axis side of the pivot 4), and if the bush 23 moves to the shaft 4 side together with the pin 21, the bush 23 will inevitably change someday.
The pin 21 and the bush 23 are prevented from moving further toward the pivot shaft 4 by coming into contact with the outer circumferential surface of the pin 21 and the bush 23 .

That is, the latch 28 and the guide surface 29.30 are connected to the pin 2.
1 and the bushing 23, it serves as a regulating surface that regulates the movement of the protrusion toward the pivot shaft 4.

Also, of the inner surface of the side wall of the container-shaped member 27, the guide surface 29.
The part farthest from the latch 28 of the locking surface 30, that is, the part adjacent to both ends of the regulating surface, corresponds to the rotation range of the pin 21 and the bushing 23 when the operating lever 2 is rotated with the operating lever 2 pulled out. A pair of stopper surfaces 38 and 39 define both ends.

The locking portion 28, which is the central part of the regulating surface, is connected to the pivot 4 and the pin 2 when the operating lever 2 is operated to the center position of the rotation range.
1, and is formed at the position closest to the pivot shaft 4 among the respective parts of the regulating surface.

The regulating surface moves away from the pivot 4 as it moves away from the latch 28.
Both end portions adjacent to the pair of stopper surfaces 38 and 39 are located at a position σ which is the most distant from the pivot 4.

When the pin 21 and the bushing 23 are in contact with the stopper surface 38 or 39 and are prevented from rotating further, the bushing 23
The pin 21 and the bush 23 are prevented from moving toward the pivot shaft 4 by coming into contact with or in close proximity to the outer circumferential surface of the pin 21 and the bush 23 .

A control cable 32 is connected to a connecting hole 31 formed in the middle of the driven lever 3, and a connecting rod 33 is connected to the tip of the pie level lever 17.

A damper device for switching the warm air outlet is connected to the control cable 32 and the connecting rod 33.
Illustrations and explanations are omitted because they are unnecessary for understanding this operating device.

In addition, 34 is a synthetic resin washer, 35 is a fixing fitting, 36
is the display board.

The display panel 36 displays the positions of the knobs 8 corresponding to four modes: "BEN L-J, R HEAT", "PIE LEVEL", and "DEFROSTER".

Next, the operation will be explained.

When the operating lever 2 is in the state shown in FIG. 1, the damper device is set to the defroster mode.

From this state, when the operating lever 2 is rotated to the center position, the driven lever 3 is also rotated accordingly,
The control cable 32 is pulled and the damper device is switched to heat mode.

If the operating lever 2 is further rotated in the same direction, the damper device is similarly switched to the vent mode.

The damper device is similarly switched when the operating lever 2 is rotated in the opposite direction.

The control cable 32 is guided by an outer cable (not shown) whose tip end is fixed to the base 1, and can act not only in the tensile force direction but also in the compression direction.

Further, when the operation lever 2 is in the center position, if it is pushed toward the pivot shaft 4 as shown by the broken line in FIG.
It is rotated clockwise in the figure, and the damper device is switched to pie level mode via the connecting rod 33.

On the other hand, if it is pulled out, it will of course switch to the heat mode again, but if the operating lever 2 is rotated while being pushed in, the pin 21 will move through the bushing 23 to the guide surface 29 or 30 (see Figure 3),
It is pushed out as the operating lever 2 rotates.

The guide surfaces 29 and 30 act as cams, and the pin 21 acts as a cam follower.

When the control lever 2 reaches one end of its rotation range, the control lever 2 is in its most pushed position, which results in the same result as if the control lever 2 were intentionally pulled out at the center position and then rotated. becomes.

Further, the stopper surfaces 38 and 39 come into contact with the outer peripheral surface of the bushing 23 at both ends of the rotation range to define the rotation operation limit of the operating lever 2, and in this state, a pushing force is applied to the operating lever 2. Also, the guide surface 29 or 30 comes into contact with the outer peripheral surface of the bush 23 to prevent the pushing operation.

In other words, the operating lever 2 can take two positions, a pushed-in position and a pulled-out position, at the center of the rotation range, but can only take one position at both ends of the rotation range.
This will prevent erroneous operation of the operating lever 2.

The operating device described in detail above is one embodiment of the present invention, and it goes without saying that the present invention can be implemented in various other forms.

For example, it is possible to reverse the vertical positions of the operating lever 2 and the driven lever 3, or it is also possible to connect the rod 33 directly to the base end of the operating lever 2 without using the pie level lever 17. .

Furthermore, the operating lever 2 only needs to be rotatable together with the driven lever 3 and movable independently in the longitudinal direction, and the means for engaging the operating lever 2 and the driven lever 3 are limited to those of the embodiments described above. It's not a thing.

Further, a regulating member main body 25 provided with the fan-shaped through hole 26
and a container-shaped member 27, the control member 27
It is ideal because it has a function of automatically returning the operating lever 2 to the pulled out position even if the operating lever 2 is rotated while being pushed in. However, as shown in FIG.
It is also possible to employ a regulating member 43 having a guide groove cut out from the straight part 42 extending radially from the center thereof.

In this case, the part of the side wall surface of the guide groove that faces the pin 21 from the axis side of the pivot 4, that is, the axis tL-
& The portion facing outward in the radial direction with respect to the center circle functions as a restricting surface that is more restrictive than the restricting surface that prevents from the guide surfaces 29, 30 and latch portion 28, and prevents erroneous operation of the operating lever 2, which is the operating member. This will be completely prevented.

The operating device according to the present invention is as detailed above and has the following features.

(1) Although the total rotation range is relatively narrow and the entire device is compact, there are only three rotation operation positions.
Since the rotation angle between the rotation operation positions is large, the required operation force is small.

(2) Since there are three rotation operation positions: both ends and the center,
Compared to the case where there are two rotation operation positions in the middle of the rotation range, the operation is simpler and there is no need to visually confirm the position, so it is suitable as an operation device for vehicle equipment.

(3) At the center of the rotation range, the knob of the operating lever protrudes furthest to the front (driver's side); from this state, push the knob inward into the device to the fourth position.
This makes it possible to secure four operating positions while keeping the amount of knob protrusion as small as possible.

The gap created between the knob and the operation panel surface at the center of the rotation range can be effectively utilized.

(4) The operable position of the operating lever is regulated by a regulating member, and the operating lever can be pushed in at the center, but not at either end, so the vehicle can be operated without fear of erroneous operation. It is suitable for operating devices for vehicle equipment that must be operated while driving.
