DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid locking device.

[0002]

2. Description of the Related Art A lid locking device for transmitting a door opening force of a lid applied to an operation knob to a locking member via an operating lever to shift the locking member from a locked position with the striker to a unlocked position. For example, Japanese Unexamined Utility Model Publication No. 5-35982 has been proposed.

In this conventional example, an operating lever is disposed so as to interfere with an operating area of a pressing claw portion formed on an operating knob, and is operated by operating the operating knob to shift a locking member to an unlocking position. Let it. The operating lever is provided with a notch, and the transmission of the operating force of the operating knob to the operating lever is cut off by moving the notch to the operating area of the pressing claw portion by operating the cylinder lock.

[0004] Stopping the operating lever with a clear moderation (click feeling) at the position where the operating force of the operating knob is connected or disconnected is not only because the operating feeling is improved, but also because the operating lever does not move to the opposite mode position unnecessarily. The click stop in the conventional example is required to elastically lock an elastic locking piece projecting from the operating lever in a cantilever shape to a click stop uneven portion formed in the holding portion of the cylinder lock. Has been achieved.

[0005]

However, the conventional example in which a click feeling is obtained by utilizing the elasticity of the elastic locking piece has the following problems. That is, the elastic locking piece is formed integrally with the operating lever made of synthetic resin in consideration of the manufacturing cost and the like, and since a large cross-sectional area cannot be taken due to a demand for miniaturization of the device, a clear clicking feeling is provided. In addition to being difficult to obtain, the click feeling is lost during long-term use due to permanent deformation due to creep or the like.

[0006] In particular, when the lock device is used in a glove box of a vehicle or the like, the temperature in the closed glove box rises to a considerable temperature in summer, so that the elastic locking piece must maintain elasticity. There is a problem that it is difficult to use a resin material excellent in creep characteristics and the like.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described drawbacks, and has as its object to provide a lid locking device capable of obtaining a clear click feeling for a long period of time.

[0008]

According to the present invention, an object of the present invention is to provide an operation knob 1 which can be rotated by a predetermined angle, and an operation knob 1
An operating lever 2 that is pressed and rotated by a pressing claw portion 10 protruding from the arm, moves the operating lever 2 in the arm length direction, and moves an idle swing portion 20 formed on the operating lever 2 to the pressing claw portion 10. The lock portion 3 that cuts off transmission of the operation force from the operation knob 1 by being located at the interference position, and is urged in the locking position direction between the striker 4 on the box side and the stroke on the locking position side by the operating lever 2. A locking member 5 whose end position is determined, wherein the locking member 5 and the operating lever 2
This is achieved by providing a lid locking device in which uneven portions 60 and 61 that click-stop at the disconnection position of the operation lever 2 are formed at the pressure contact interface with the lid.

In the present invention, an operation knob 1 rotatably mounted on a base such as a case 7 is provided with a pressing claw portion 10, and when the operation knob 1 is rotated, the pressing claw portion 10 rotates around a predetermined rotation center. The arm portion of the rotatable operating lever 2 is pressed to rotate the operating lever 2. Further, the operation lever 2 can be moved in the arm length direction by the lock portion 3, and the transmission of the operating force from the pressing claw portion 10 is cut off by positioning the idle swing portion 20 in the rotation area of the pressing claw portion 10. .

The operating lever 2 is a component that rotates around a fulcrum with a load point on the arm portion from the pressing claw portion 10 as an application point, and transmits the force of the operation knob 1 to the locking member 5. The arrangement order of the two action points on the arm portion is appropriately determined in consideration of the entire layout. The idle swing portion 20 of the operation lever 2 is a detour portion formed in the arm portion so that the interference with the pressing claw portion 10 does not occur when the pressing claw portion 10 rotates, and the arm portion is cut off. It can be formed by chipping or bending the arm.

The lock portion 3 is operated by a predetermined operation.
A rotary knob that can be rotated without using a genuine key other than a so-called cylinder lock that can be rotated only with a genuine key that matches the code is sufficient as long as the member can be moved between the cutting position and the coupling position. Or a slide switch or the like can be used, and when using a lock portion 3 such as a cylinder lock in which a lock position and an unlock position are selected by a rotation operation, the lock portion 3 is provided so as to protrude therefrom. When the operating lever 2 is loosely fitted to the boss, the locking portion 3 is formed.
Can be converted into an operation of the operating lever 2 in the arm length direction.

The locking member 5 is a component that moves between the locked position with the striker 4 and the unlocked position, and the moving path is irrespective of whether it is linear or curved. It is sufficient if the point of action from the lever 2 is displaced in the rotation direction of the operating lever 2 between the locked position and the unlocked position.

"The stroke end position on the locking position is determined by the operating lever 2" means that the locking member 5 is pressed against the operating lever 2 by the urging force on the locking member 5 and is held at the locked position. In this state, the operating lever 2 is urged by the locking member 5 and pressed against a predetermined stopper, thereby restricting free movement and preventing rattling noise during traveling. . Further, the “stroke end position on the locking position side” is made equal at least at both the connection and disconnection positions of the operation lever 2.

The click-stop concavo-convex portions 60, 61 formed on the press-contact surface between the operating lever 2 and the locking member 5 have the appropriate convexity on the convex portion 61 formed on one side and the concave portion 60 on the other side. It is a component that can be fitted by fitting, and it does not matter which of the actuating lever 2 and the locking member 5 the projection 61 is formed. In addition, the concave / convex portion 6 for click stop
The fitting depths 0 and 61 are appropriately determined in consideration of a desired sense of moderation and a force required for fitting and disengaging.

Further, in the present invention in which the locking position of the locking member 5 is determined by the height of the pressure contact interface of the operating lever 2, the locking member 5 is locked when the concave and convex portions 60 and 61 are not fitted. In order to be displaced slightly from the position to the unlocking position side, it is desirable to set the locking end side stroke end position so that the locking performance to the striker 4 does not deteriorate even in this position.

By constantly holding the operating lever 2 and the locking member 5 in a pressed state, the click projections and depressions 60 and 61 formed on the pressing interface are brought into an engaged state by the urging force on the locking member 5. Therefore, a good click feeling can be obtained for a long period of time without deteriorating the performance, and the operating lever 2 does not move unnecessarily in the arm length direction.

Each of the above components can be assembled on a single base such as the case 7.
For example, only the lock portion 3 is assembled to another base, the lock portion 3 is arranged on the driver's seat side, and the base on which the locking member 5, the operation knob 1 and the like are assembled is arranged on the passenger's seat side, and locking by remote operation is performed. It is also possible to configure so that operation is possible.

According to the second aspect of the present invention, an effective modification for reducing the number of components and simplifying the structure is provided. That is, in the second aspect of the present invention, the case 7 is provided with the double torsion spring 8.
The double torsion spring 8 is formed by integrally forming torsion springs 81 and 82 whose winding directions are reversed to the left and right with a support portion 80 for the case 7 holding the operation knob 1 and the locking member 5 interposed therebetween. Torsion spring 81
The operating knob 1 to the other torsion spring 82
This urges the locking member 5 toward the initial position.

In the figure, reference numeral 7 denotes a case, which is fixed to the lid by a tapping screw or the like screwed into a screw insertion hole 70 formed on the back surface.

As shown in FIG. 2, an operation knob 1 whose rear surface is biased to an initial position where the rear surface abuts against a stopper 71 of the case 7 is rotatably supported around a hinge 11 on the front surface of the case 7, as shown in FIG. Is provided with a pressing claw portion 10 for operating an operation lever 2 described later.

A cylinder lock (lock portion 3) is arranged beside the operation knob 1, and a boss 3 protruding from the cylinder lock 3 is provided.
The actuating lever 2 is disposed with one end loosely fitted at 0. The operating lever 2 is extended to the inside of the locking member receiving portion 72 formed on the rear side of the operating knob 1, and is operated along the arm length direction, that is, the longitudinal direction by rotating the cylinder lock 3. You. As shown in FIG. 2, the lever insertion opening 72 a formed in the locking member housing portion 72 is elongated in the moving direction of the locking member 5, and the operating lever 2 is centered on the connecting portion with the cylinder lock 3. The rotation of the locking member 5 in the moving direction is permitted.

Further, the operating lever 2 has an idle swing portion 20 at a position overlapping the rotation locus of the pressing claw portion 10 of the operation knob 1 when the cylinder lock 3 is held at the lock position. The idle swing portion 20 is formed by bending or notching the operating lever 2 so as to avoid interference with the rotation locus of the pressing claw portion 10 of the operation knob 1. In the present embodiment, the operating lever 2 is moved to the rear side. It is formed by bending in an L shape.

On the other hand, the locking member housing portion 72 is opened upward, and the locking member 5 is stored in a state of being dropped from the opening portion. The locking member 5 is vertically movable within the locking member housing portion 72, and the guide protrusion 50 formed on the side wall portion is formed into a guide groove 72 on the inner wall of the locking member housing portion 72.
The rattle is prevented by being fitted to b. The locking member 5 is urged in a protruding direction, and a pressing contact piece 51 protruding from a lower portion of the rear surface of the locking member 5 is pressed against the operating lever 2 so that the stroke end of the protruding side of the locking member 5. The position is determined. A groove-shaped concave portion 60 is provided on the pressing surface of the pressing piece 51 against the operating lever 2, and a convex portion 61 is provided on the operating lever 2. When the cylinder lock 3 is at the lock position, the convex portion 61 is formed. It fits into the recess 60 with an appropriate click feeling.

In order to simultaneously urge the locking member 5 and the operation knob 1 in a predetermined direction, the case 7 is provided with a torsion whose winding direction is reversed left and right across a support portion 80 bent in a U-shape. A double torsion spring 8 integrally formed with springs 81 and 82 is mounted. The double torsion spring 8 is formed such that the free end of one of the torsion springs 81 is formed by the operation knob 1 and the other free end thereof is formed on the back surface of the locking member 5 after the supporting portion 80 is placed on the seat surface formed on the case 7. The torsion springs 81 and 82 are bent in the winding direction by a predetermined angle in the mounted state, and the operation knob 1 is moved to the initial posture side and the locking member 5 is ejected in the mounting state. More precisely, it is urged in the direction of the locking position with the striker 4.

The supporting portion 80 of the double torsion spring 8 is provided with reverse torsion springs 81 and 82.
In order to receive the rotational reaction force in the same direction from, it is possible to arrange at a predetermined position without using a special shaft portion or the like, but, as shown in FIG. It is desirable to form a projection 73 on the seat surface, into which the support portion 80 fits.

Therefore, in this embodiment, the locking member 5 is urged by the double torsion spring 8 and held at the stroke end position in the protruding direction.
In this position, the locking member 5 protrudes from the upper end edge of the locking member housing portion 72 and closes in side view in cooperation with auxiliary arms 74 formed on both sides of the locking member housing portion 72. The formed striker accommodation space 9 is formed (see FIG. 2).

In this configuration, when the lid is rotated from the open state to the closed state, the inclined surface 53 formed on the upper rear surface of the locking member 5 abuts on the striker 4 fixed in the box, and the locking member 5 is rotated. Moves in the settling direction against the urging force of the double torsion spring 8 and receives the striker 4 in the striker accommodating space 9 and then returns to the stroke end position on the ejection side, that is, the locking position of the striker 4 by elastic restoring force. Then the lid cannot be opened.

The lid is opened from the closed state by rotating the operation knob 1 from the initial position. As shown in FIG. 2, the rotation of the operation knob 1 causes the pressing claw portion 10 of the operation knob 1 to operate. The operation lever 2 is rotated around the connection portion with the cylinder lock 3 by interfering with the lever 2. With the rotation of the operating lever 2, the pressure contact piece 51 of the locking member 5 is pushed down, and the locking member 5 moves in the unlocking direction with the striker 4 to open the striker accommodation space 9, and the striker from the opening portion 4 can be released.

On the other hand, when the operation knob 1 is operated, the cylinder lock 3
Is locked, as shown in FIG.
Since the pressing claw portion 10 cannot pass through the idle swing portion 20 and press the operation knob 1, the operating lever 2 does not operate, and the operation of the locking member 5 becomes impossible.
