DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lever mounting structure for an operating lever device such as a lever type heater control device.

[0002]

2. Description of the Related Art A heater control device for an automobile is a device mounted on an instrument panel in a vehicle compartment for selectively introducing hot air or cold air into the vehicle interior. As shown in FIG. 5A, the front panel 1 of the heater control device is provided with a lateral slit 2 through which the operating lever 3 projects. As shown in FIG. 5B, the other end 3a of the operation lever 3 is pivotally attached to a hole provided in the apparatus main body.

Therefore, the projecting end of the operating lever 3 is
When the control lever 3 is slid along, the operation lever 3 rotates about the pivot point, and operates a damper or a switch attached to the air conditioner by moving a wire or a rod (not shown) connected to the operation lever 3 so as to operate at an appropriate temperature. It is configured such that an appropriate amount of wind can be introduced into the vehicle interior.

As a conventional means for attaching the operating lever to the apparatus main body, an elongated hole 4 having an elongated hole 4 and a guide pin 5 shown in FIGS. 6A and 6B is used.
And the guide pin 5 is engaged with a guide groove 8 provided in the apparatus main body, and the pin 5 is guided by the guide groove 8, The tip of the operation lever 3 is made to perform a pseudo-linear motion.

[0005]

In the conventional operation lever mounting means, when the operation lever 3 is mounted on the apparatus main body, the guide pin 5 of the operation lever 3 needs to be moved into the guide groove 8, so that the operation lever 3 is required. An opening 9 through which the guide pin 5 can be inserted is provided in the guide groove 8.

In the guide groove 8, the operation trajectory of the operation lever 6 is determined by the movement of the guide pin 5, so that the opening 9 cannot be made wide. Therefore, when assembling the operation lever 6, there is a problem that the guide pin 5 does not properly match the opening 9 and insertion becomes difficult.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to realize a lever mounting structure for an operation lever device which is easy to assemble.

[0008]

In the lever mounting structure of the operating lever device according to the present invention, a front panel having a substantially linear opening and one end protruding from the opening of the front panel are operable from outside. Operating lever, and an apparatus main body disposed on the back side of the front panel to guide and support the operating lever, the operating lever having a long hole at the other end and a guide pin at an intermediate portion, A boss having a projecting portion in which the device main body is engaged with a long hole of the operation lever; a guide groove for guiding a guide pin of the operation lever to perform a pseudo-linear movement of a tip end of the operation lever; and a wall of the guide groove. In the lever mounting structure of the operation lever device having the provided guide pin insertion opening, the opposing width is set such that the opposing width is directed outward from the groove from both edges of the opening provided on the wall of the guide groove. Formed to expand gradually Characterized in that a pair of walls of the guide pin guide that.

By adopting this configuration, a lever mounting structure of the operation lever device which is easy to assemble can be obtained.

[0010]

According to the present invention, as shown in FIG. 1, guide walls 24 and 24 'for guiding the guide pin 17 into the groove are provided in the guide pin insertion opening 23 of the guide groove 13.
When assembling the operation lever 10 to the apparatus main body, the guide pins 17 can be guided into the guide grooves 13 by the guide walls 24, 24 ', so that the assembling becomes extremely easy.

[0011]

1 and 2 show an embodiment of the present invention.
1A is a plan view, and FIG. 1B is bb in FIG. 1A.
2 is a sectional perspective view taken along a line. In both figures, 10 is an operation lever, 11 is an apparatus main body, 12 is a boss provided in the apparatus main body, and 13 is a guide groove provided in the apparatus main body.

The operation lever 10 is provided with a lever portion 14.
Has a flat portion 15 at one end thereof, and a long hole 16 is formed in the flat portion. A guide pin 17 is formed on a lower surface of an intermediate portion of the lever portion 14 of the operation lever 10.

The boss portion 12 of the apparatus main body 11 has a flat portion 18 for supporting the flat portion 15 of the operation lever 10. The flat portion 18 engages with a long hole 16 of the operation lever 10. A tongue piece 20 having a projection 19 serving as a pivot, and a pair of left and right engagement claws 21 and 21 ′ formed in an inverted L-shape so as to prevent the operating lever 10 engaged with the projection 19 from coming out.
And a pair of left and right guides 22, 22 'for guiding the operation lever 10 when the operation lever is assembled.

A guide groove 1 provided in the apparatus main body 11 is provided.
Reference numeral 3 denotes a groove for engaging the guide pin 17 of the operation lever 10 to guide one end of the operation lever 10 so as to perform a pseudo-linear motion parallel to the front panel. An opening 23 for inserting the guide pin 17 of the lever 10 into the groove is formed. And the opening 2
3, a pair of walls 24, 2 for guiding the guide pins from both edges.
4 'is provided.

A pair of walls 24, 2 for guiding the guide pins are provided.
4 'is provided so that the facing width gradually increases outward from both edges of the opening 23 of the guide groove 13, and the wall has a linear shape as shown in FIG. Even so,
Alternatively, it may have a curved shape as shown in FIG.

An assembling method for assembling the thus constructed embodiment will be described with reference to FIG. 2A is a plan view, and FIG. 2B is a cross-sectional view taken along line bb of FIG. In this assembling method, first, the tip of the lever portion 14 of the operation lever 10 is inserted into a slit of a front panel (not shown), and at the same time, the flat portion 15 of the operation lever 10 is
The second protrusion 19 is pressed and inserted between the flat portion 18 of the boss 12 and the engagement claws 21 and 21 ′ while bending the tongue piece 20.

Next, the operating lever 10 is pushed forward in the direction of arrow A, and pushed forward until the projection 19 of the boss 12 engages with the elongated hole 16 of the operating lever 10 to reach the state shown in FIG. In this state, the guide pin 17 of the operation lever 10 is completely inserted into the guide groove 13. At this time, the operation lever 1
0 is guided by the guides 22 and 22 'and the direction of the operation lever 10 is regulated.
7 is guided in the direction of the opening 23. Guide pin 17
Is guided by a pair of guide walls 24 and 24 ′ provided on the left and right sides of the opening 23 of the guide groove 13, and thus can be inserted into the guide groove 13 very easily.

[0018]

According to the present invention, a guide wall is provided at the opening for inserting the guide pin of the operation lever into the guide groove, so that the guide pin can be prevented from being caught and the operation lever can be connected to the apparatus body. Assembly becomes extremely easy, which can contribute to improvement in productivity of the lever type heater control device.
