BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is designed to allow an operator to perceive two positions, a locked position and an unlocked position, in a rotating lever for interlocking a lock mechanism of a door of a vehicle or a lid of a storage box in a vehicle compartment. And a click device.

[0002]

2. Description of the Related Art In a conventional mechanism of this type, a V-shaped spring piece is fixed to a fixing member so that a protrusion of a lever pushes the top of the spring to pass therethrough. Is generally the locking position and the other side is the unlocking position (for example, Japanese Utility Model Laid-Open No. 64-14875).

However, such a structure cannot be used when the locked position and the unlocked position are apart from each other by a certain degree or more, and since the spring piece has to be assembled to the fixing member, the number of parts and the number of steps are reduced. Many costs increase.

SUMMARY OF THE INVENTION An object of the present invention is to construct a click mechanism without using other parts outside the lever and the lever holding portion.

[0005]

Means for Solving the Problems According to the means for solving the above problems in the present invention, in a rotating lever for transmitting the rotation of an operating portion to a lock mechanism, an end portion of a tongue piece formed in a part of the rotating lever is provided. The click protrusion has a click protrusion that is provided so as to project laterally, and a moderation protrusion that is formed by deforming a part of a lever holding portion that pivotally supports the rotation lever so as to project into the locus of the click protrusion. And one of the moderation protrusions, and two of the other are provided at a required interval.

[0006]

Since the above means are provided, when the lever is rotated, the operating force fluctuates twice when passing through the two moderation protrusions when the click protrusion is one, thereby locking or unlocking. 2 can be perceived, and when the number of click protrusions is 2, the two positions can be perceived by sequentially passing through one moderation protrusion and changing the operating force twice.

The rear surface 6 has a non-circular recess 20 and an inclined guide surface 21 reaching the recess 20 from the rear surface.

The key lever 18 is made of a hard plastic material having elasticity, and as shown in FIG.
Each lever 22 is provided with a slit 23, a connecting hole 24, two inclined slits 25, and two tapered guide pieces 26 from the center side. When the crank-shaped portions 27a, 28a of the rods 27, 28 shown in FIG. 3 are pushed between the guide pieces 26, 26, the guide pieces 26,
26 and the slit 23 are elastically deformed to reach the connecting hole 24. At this point, the elastically deformed portion is restored to hold the crank-shaped portions 27a and 28a without rattling and prevent the escape.

As shown in FIG. 4, the key lever 18 is provided with a pair of stopper pieces 29, 29 protruding from the key lever 18, which cooperates with the stopper 14 to regulate the locked position and the unlocked position. Further, a pair of U-shaped slits 30 and recesses 31 shown in FIGS. 4 and 5 are provided on the rear surface of the key lever 18,
A pair of elastic tongues 32 are formed by the U-shaped slit 30, and click protrusions 33, 33 are provided on the rear surface of the tip end thereof. On the other hand, on the front surface of the key lever holding portion 13 of the bracket 6, a moderation projection 34 projecting in the locus of the click projection 33 is provided by extrusion, and both projections 33,
Due to fluctuations from the operating force that occurs when 34 is disengaged,
The locked position and the unlocked position can be perceived. Then, at the locked position and the unlocked position of the key lever 18, the outer surfaces of the click protrusions 33 are engaged to brake the key lever 18 and prevent the key lever 18 from returning to the intermediate position.

FIG. 6 shows an example in which only one click protrusion 33a is provided, and an arm 32 having a U-shaped slit 30a in a semi-circular recess 31a and having the click protrusion 33a.
a and the key lever holding portion 13a on the top of the bracket 6a is provided with two moderation protrusions 34a and 34b. The central angle of both protrusions 34a and 34b is the key lever 18a.
The rotation angle of the click projection 33a is narrowed by about the diameter of the click projection 33a.

In the state shown in the drawing, the click protrusion 33a is in contact with the left side of the moderation protrusion 34a and in contact with the right side of the recess 31a, so that the rotation of the key lever 18 is restricted, and the key lever 18 is rotated clockwise from this position. When the click protrusion 33a moves, the click protrusion 33a moves over the two moderation protrusions 34a and 34b and moves to the right side of the moderation protrusion 34b, and at the same time, the left end of the recess 31a contacts the left end of the moderation protrusion 34a and rotation thereof is restricted.

The rotor of the cylinder lock 1 has an insertion hole 36 for the key K at the rear end, and the outer periphery of the body portion 37 of the outer 35 is
A circumferential groove 37 is dug in the middle, a flange 39 that can pass through the mounting hole 3 is projected behind the groove 37, and an axial ridge 40 is projected in the vertical direction. A non-circular end portion 41 that fits into the non-circular concave portion 20 is integrally formed at the tip of the rotor that is rotated by the key K.

The clip 43 for fixing the cylinder lock 1 to the outer holding portion 5 is made of an elastic hard synthetic resin, and as shown in FIGS. 3 and 7, the circumference is divided into four at the front end of the cylindrical portion 44. The inwardly inclined claw portion 45 is continuously provided, and the circumferential portion 4

And a U-shaped hollow key 48 is formed in the lengthwise direction of the cylindrical portion 44. The outer diameter of the cylindrical portion 44 is equal to the inner diameter of the mounting hole 7, and the distance between the rear end of the check projection 46 and the front surface of the locking flange 47 is equal to the thickness of the outer holding portion 5.

When the clip 43 is pushed into the mounting hole 7 of the frame 4 from the rear with the key groove 8 and the hollow key 48 aligned, the vicinity of the check projection 46 is deformed inward and passes through the mounting hole 7. Then, by restoring after passing, the non-return projection 4
The outer holding portion 5 is sandwiched between the rear end of 6 and the front surface of the locking flange 47 to be in the fixed state shown in FIG.

Next, the cylinder lock 1 is attached to the axial projection 40 thereof.
Align the hollow key 48 with the mounting hole 3 and the clip 43.
When pushed in, the flange 39 comes into contact with the locking flange 47 of the clip 43 and is prevented from moving forward, as shown in FIG.
Since the claw portion 45 of the clip 43 is inserted into the circumferential groove 38, the backward movement is also prevented, and the axial ridge 40 has the hollow key 48.
The cylinder lock 1 is locked in the keyway 8 via
It means that it is fixed to the frame 4. At this time, the non-circular end portion 41 of the rotor is fitted into the non-circular concave portion 20 of the key lever connecting portion 16 directly or by being guided by the guide surface 21 and is rotationally connected, so that the key K is inserted. By rotating, the key lever 18 is rotated and the rods 27 and 28 can be moved.

When the key K is rotated, the click protrusion 3
Since the operation force fluctuates each time 3, 33a exceeds the moderation projections 34, 34a, it can be surely known that the operation force has moved to the locking position and the unlocking position, and erroneous operation can be prevented.
