Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an operating lever device with a moderation mechanism used for controlling the temperature of an automobile, switching the blowout mode, etc.

[Prior Art] An operating lever device with a moderation mechanism has been proposed in which a leaf spring is loosely fitted into the operating lever and the friction member with a recess and the leaf spring slide. (Japanese Patent Publication No. 56-51371) Also known is a click mechanism for a lever device in which one end of a leaf spring is pivoted or fitted to an operating lever. (Utility Model Application Publication No. 100717/1983) [Problems to be solved by the invention] However, these lever devices do not sufficiently consider elastic support in the operating direction of the lever by the leaf spring attached to the lever. This resulted in the following drawbacks.

1. A large operating force is required from the beginning to operate the lever.
Therefore, the operability is poor.

2. Due to the poor vibration of the leaf spring, there is no light operation sound.

The purpose of the present invention is to improve the operability of a lever in an operating lever device with a moderation mechanism and to improve the acoustic properties of a spring attached to the lever.

[Means for Solving the Problems] The operating lever device with moderation mechanism of the present invention includes an operating lever that is movable in a fixed direction, one end of which is fixed to the operating lever, and the other end that is movable in the moving direction of the operating lever. a plate-shaped or rod-shaped spring having a free end that is elastically displaceable in a direction perpendicular to the direction of movement of the lever; A locking member provided within the engagement surface and having a recess for releasing the lock of the free end of the spring, and a collision mechanism that causes the spring to collide with the operating lever when the lock of the free end is released. It consists of a moderation mechanism.

[Operations and Effects of the Invention] The operating lever device with a moderation mechanism of the present invention has such a structure that one end of the spring that can be elastically deformed in the operating direction of the lever is fixed to the lever, and the other end is a free end. When operating the lever, the operating force of the lever is initially small and increases in proportion to the amount of displacement of the spring. Therefore, it has excellent operability.

Furthermore, since the spring has a collision mechanism in which the spring collides with the operating lever when the free end is released, a light sound is generated due to the vibration of the spring when the lever operation is completed. Therefore, the driver does not need to visually confirm the completion of the operation.

[Embodiment] Next, an operating lever device with a moderation mechanism of the present invention will be explained based on a first embodiment shown in FIGS. 1 to 3.

Reference numeral 1 indicates an operation panel mounted near the driver's seat such as a front panel provided at the front of the passenger compartment of the automobile, and 2 indicates an air conditioner (not shown) provided on the operation panel 1 so as to be movable in the horizontal direction. ) etc., an operating lever for manually controlling an operated mechanism by a driver; 3 is a spring attached to the upper surface of the operating lever; 4 is a cable connecting the operating lever and the operated mechanism.

In this embodiment, the operation panel 1 is formed horizontally, and has a slit 11 through which the operation lever 2 is inserted.
A front plate part 12 is provided with a front plate part 12, and oval holes 13, 14, 15, 16, and 17 are formed that protrude from the back surface slightly above the slit 11 of the front plate part 12 and serve as recesses on an arc. and a shelf plate portion 18 which is a locking member at the free end of the spring. The direction of the slit 11 may be vertical or other direction, in which case the locking member is also provided corresponding to the direction of the slit 11.

The operating lever 2 is inserted into the slit 11 of the operating panel 1.
The rear end 2A located inside the front panel is pivotally attached to the front panel component 19 through a formed elongated hole 22 with screws 21 while allowing some displacement in the longitudinal direction. A knob 23 is fastened with a screw 24 to the front end 2B protruding into the vehicle interior, and a pin 41 for hooking the tip 4A of the cable 4 is provided on the lower surface of the intermediate portion 2C.
On the upper surface, there is a claw 27 that serves as a collision mechanism member for the spring 3.
is installed protrudingly. In this embodiment, the claw 27 is formed by making a U-shaped cut in the operating lever 2 and pulling the cut upward. The lengths of the oval holes 13 to 17 of the operation panel 1 are set in accordance with the amount of displacement of the lever 2 in the longitudinal direction.

In this embodiment, the spring 3 is formed by bending a plate spring member, and one end has two small holes 31 and 32 bored therein, and the small hole 31 and the small hole 20 provided on the upper surface of the central portion 2C of the lever 2 are connected to the rivet 5. Further, the head 41A of the pin 41 protruding from the upper surface of the lever 2 is passed through the small hole 32, and the protruding end is caulked, thereby fixing the fixed end 3.
A, and the other end is the oblong hole 1 of the operation panel.
The free end 3B is an enlarged upward spherical protrusion 33 having a diameter smaller than the width of 3 to 17 by a predetermined amount, and the intermediate part is bent diagonally upward from the fixed end 3A and twisted at 90 degrees. Vertical surface part 3
5 is formed, and a hole 37 is formed which is bent horizontally from the vertical surface portion 35 and loosely fits into the pawl 27 protruding from the operating lever.
This allows the free end 3B of the spring 3 to be elastically displaced within a predetermined range in the vertical and horizontal directions. Further, in this embodiment, the claw 27 and the edge of the hole 37 constitute a collision mechanism.

The protrusion 33 at the free end of the spring 3 is pressed against the lower surface 18A of the shelf section 18 of the operating panel by spring force, and as the lever 2 moves, a constant locking force is exerted by the frictional force with the lower surface 18A. is pulled in the reverse direction. Therefore, the vertical surface portion 35 of the spring 3 is bent and elastically deformed. The edge of the spring hole 37 contacts the pawl 27 to limit the amount of displacement of the spring 3 to a set value and prevent the operating lever 2 from returning excessively. When the protrusion 33 comes to the position of the holes 13 to 17, which are recesses provided in the shelf section 18, the locking force due to the friction is canceled, and the vertical surface section 35 is flipped and displaced in the opposite direction. At this time, the edge of the hole 37 formed in the spring on the side opposite to the moving direction of the operating lever 2 collides with the pawl 27, producing a deceleration sound. The moderation sound produced at this time becomes a diaphragm because one end of the spring is fixed and the other end is free or weakly locked, resulting in a clear tone.

In addition, if the pressure force between the spring 3 and the lower surface 18A is insufficient only by the elastic force of the spring itself, a coil spring may be installed around the pawl 27, for example.

4 and 5 show a second embodiment of the invention.

In this embodiment, the spring 3 is fixed by fitting the claw-shaped bent portion 30 provided at one end 3A of the spring into the hole 25 provided in the operating lever 2, and by fitting the claw-shaped bent portion 30 provided at one end 3A of the spring
A is passed through the small hole 32 and the protruding end is caulked. This facilitates the work of fixing the spring 3 to the operating lever 2. Further, in this embodiment, the free end of the spring 3 is brought into pressure contact with the upper surface 18B of the shelf board portion 18, and the protrusion 34 is made to bulge downward. Furthermore, a hole 2 in the operating lever 2 is provided with a downward pawl 36 formed by cutting the spring 3 and bending it downward.
8 to prevent excessive displacement of the spring 3 and to form a collision mechanism between the spring 3 and the operating lever 2.

FIG. 6 shows a third embodiment.

In this embodiment, the spring 3 is fixed by inserting two downward engaging claws 30 and 40 provided at one end 3A into a rectangular hole 44 provided in the lever according to the distance between the claws 30 and 40. This is done by fitting it in and bending the downwardly protruding tip outward. This further facilitates the work of fixing the spring.

In this embodiment, the spring collision mechanism is constituted by two pawls 47 and 48 provided upwardly from both sides of the operating lever 2 so as to loosely sandwich the spring 3, and both side edges of the spring 3. In both the fourth and fifth embodiments, the two pawls also have the function of preventing excessive displacement of the spring.

The shape of the spring is not limited to the above embodiments, and may have a shape in which a vertical surface part is bent diagonally upward from the fixed end and formed by folding it double along the center line in the middle part, and furthermore, other shapes may be used. Shaped leaf springs and rod-shaped springs can also be used. The spring is fixed to the operating lever by fixing one end of the spring to the operating lever at two points in order to prevent the spring from rotating. If the structure is such that it can be prevented, it may be fixed at one point.

9 and 10 show a sixth embodiment.
