DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a lock device used in, for example, a push-open type ashtray case / accessory case or cup holder provided on an instrument panel side of an automobile. Things.

[0002]

2. Description of the Related Art An example of a conventional lock device of this type is disclosed in Japanese Patent Publication No. 25816/1990.
The conventional lock device is proposed as a lock device of a push-open type ashtray of an automobile. Although not specifically shown, an ashtray case as a moving body can be moved into and out of a housing fixed to an instrument panel side. And biasing the ashtray case in a direction protruding from the opening of the housing via an urging spring pressure, while a cam member having a cam groove formed on the housing side is provided rotatably, and is provided on the ashtray case side. By providing a pin member that moves in the cam groove of the cam member and locking the pin member to the lock portion of the cam groove, the ashtray case is moved to the closed position in the housing against the urging spring pressure. In this state, the ashtray case is further pushed slightly into the housing to release the locking of the cam groove of the pin member with respect to the lock portion. It has a structure capable of projecting in the biasing spring pressure to open position outward from the opening.

In such a conventional lock device,
When the cam member is mounted on the housing side, the cam member is pivotally mounted on the housing using a stepped mounting shaft, and between the head of the mounting shaft and the corresponding surface of the cam member. With the torsion spring interposed, one end of the spring is hooked on a locking portion on the cam member side, and the other end of the spring is hooked on a locking portion provided on the housing side. A configuration is employed in which the cam member is always elastically urged in one predetermined direction until the stopper wall portion is restricted by the pressure. For this reason, when you push the ashtray case into the housing,
The pin member provided on the ashtray case side abuts against the outer peripheral guide wall of the cam member, and rotates the cam member in the direction opposite to the biasing direction against the spring pressure of the torsion spring. It is automatically guided into the cam groove of the member,
Since it locks to the lock portion of the cam groove, the ashtray case is securely locked at the closed position in the housing,
When the ashtray case is further pushed slightly into the housing in this state, the pin member comes off the lock portion of the cam groove, and the cam member turns in the biasing direction by the spring pressure of the torsion spring. This allows the pin member to be completely removed from the cam groove and to ensure that the ashtray case projects from the opening of the housing to the outward open position.

[0004]

However, in the conventional locking device, the positive application of the spring pressure of the torsion spring to the cam member certainly ensures that the cam member is always moved in one predetermined direction. It becomes possible to energize. However, the use of a torsion spring, on the other hand, requires not only to separately form a locking portion for hooking both ends of the torsion spring, but also when the cam member is mounted on the housing side via a mounting shaft member, Since both ends of the torsion spring must be individually hooked onto the above-mentioned locking portions while taking the directionality into account, the mounting work of the cam member becomes extremely difficult due to this. Further, when the cam member is turned in the biasing position or the biasing direction, a loud clicking noise is generated, so that there is a possibility that the luxury feeling of the apparatus itself is impaired.

[0005]

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the problems of the conventional locking device, and includes a cam member having a cam groove formed therein, and a cam member having a cam groove formed therein. A movable pin is locked in the closed position in the housing against the urging spring pressure by locking the pin in the lock portion of the cam groove. By pushing the moving body into the housing,
The cam member is provided on the assumption that the locking member of the moving member that releases the locking of the cam groove of the pin member to the lock portion and projects the moving member from the opening of the housing to the outside open position by the urging spring pressure is applied. A rotating shaft is integrally provided on the cam member, and a bearing for rotatably holding the rotating shaft is provided at a mounting portion of the cam member. The cam is turned and swung by holding the rotating shaft by the bearing. The cam member is supported so as to be able to rotate, and the cam member is maintained in a predetermined posture via the posture maintaining means, and the cam member is turned in a predetermined direction only by the moving force of the pin member applied to the cam member.

[0006]

Therefore, according to the present invention, when the cam member is mounted on the mounting portion, the distal end of the rotating shaft can be simply mounted on the bearing without the complicated work involved in the use of the torsion spring as in the prior art. By simply inserting the cam member, it is possible to pivotally and swingably mount the cam member, so that the mounting operation of the cam member is greatly simplified, and the operation of the posture maintaining means causes the cam member to assume a predetermined posture. Since it is maintained, a reliable turning motion is always guaranteed.
In actual operation, if the moving body is pushed into the housing against the biasing spring pressure, the pin member forcibly turns in a predetermined direction while pressing the cam member with its own moving force. Thereby, the pin member is automatically locked in the lock portion of the cam groove, and the moving body can be securely locked at the closed position in the housing. Further, when the moving body is further pushed into the housing in this state, Since the pin member is disengaged from the lock portion of the cam groove and again forcibly turns the cam member in a predetermined direction, the movable body is moved outward from the opening of the housing by its own biasing spring pressure. It is guaranteed to protrude to.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a lock device according to an embodiment of the present invention. A movable member, such as a movable member, is supported so as to be able to protrude and retract, and the movable member is urged in a direction protruding from an opening of the housing via urging spring pressure, while a cam member having a cam groove formed on the housing side can be turned. And a pin member that moves in the cam groove of the cam member is provided on the moving body side, and the pin member is locked in the lock portion of the cam groove, so that the moving body is opposed to the urging spring pressure. In this state, the movable body is slightly pushed into the housing to release the locking of the cam groove of the pin member to the lock portion, and the movable body is removed from the opening of the housing. To the open position It is assumed that the cam member is turned in a predetermined direction in accordance with the spring pressure of the torsion spring or in accordance with the spring pressure. The present invention is characterized in that a configuration is adopted in which the cam member is turned in a predetermined direction only by the moving force of the pin member interlocking with the moving body.

For this reason, in this embodiment, as shown in FIG. 1, a rotary shaft portion 4 having a spherical distal end portion 4a is provided vertically on the lower surface on the base end portion side of the cam member 1 so as to be vertically suspended. A cylindrical bearing portion 5 that rotatably holds the rotating shaft portion 4 is integrally provided on the rear end side, and the cam member 1 is attached to the housing H by holding the rotating shaft portion 4 by the bearing portion 5. The compression coil spring 6 is interposed between the lower surface of the cam member 1 and the bottom surface of the housing H, and the base edge of the cam member 1 is provided on the rear wall of the housing H. The cam member 1 is always maintained in a horizontal position by the action of the compression coil spring 6 and the block portion 7, and the free end side thereof is provided only when the lock is released. For swinging against the spring pressure of the compression coil spring 6. It is adopted. Therefore, in the present embodiment, the compression coil spring 6 and the block 7 constitute a posture maintaining means. In the drawings, reference numerals 8 and 9 denote stopper wall portions for restricting the turning movement of the cam member 1 in the left-right direction.

Further, as shown in the figure, the cam groove 2 having the inlet 2a, the lock portion 2b, and the outlet 2c is formed at a predetermined portion of the cam member 1, as shown in FIG. In the embodiment, a first guide wall 3a is formed on the outer peripheral surface on the free end side, and an opposing surface defining the inlet 2a of the cam groove 2 in cooperation with the first guide wall 3a. A second guide wall portion 3b is formed on the edge side, and a switching wall portion 3c continuous from the second guide wall portion 3b on the opposite edge side.
And the third guide wall 3d.
The end of d is connected to the side of the inclined outlet 2c, and during the linear movement of the pin member P in conjunction with the moving body B, the guide wall portions 3a, 3b.
The cam member 1 is forcibly turned in a predetermined direction by using only the force applied to 3d.

Therefore, when the cam member 1 is mounted on the housing H side, the present embodiment simply employs the above-mentioned rotary shaft because a torsion spring for urging the cam member 1 in a predetermined turning direction is not used. Just by setting the compression coil spring 6 around the part 4 and inserting the spherical tip 4a of the rotating shaft part 4 into the cylindrical bearing part 5, as shown in FIGS. Since it is pivotally and swingably mounted on the housing H, the mounting operation of the cam member 1 is greatly simplified and the cam member 1
Is mounted and supported on the upper surface of the block portion 7 and receives the spring pressure of the compression coil spring 6 from below, so that the horizontal posture is reliably maintained and the cam member 1 is stabilized. The swiveling motion is assured. In addition, after the cam member 1 is attached to the housing H, the cam member 1 may be pivoted to a predetermined standby position, so that the direction of insertion of the rotating shaft 4 into the bearing 5 may be required. Absent. Also, in this embodiment, a spring means is used. Since the spring means is a compression coil spring 6 for maintaining the horizontal posture of the cam member 1, when the cam member 1 is mounted, the spring means is the same as the conventional one. Complicated work is never required.

Then, after that, if the moving body B is pushed into the housing H against the urging spring pressure (not shown), the moving body B is moved to the position shown in FIG.
As shown in (A), a pin member P provided on the rear end side of the moving body B comes into contact with the first guide wall 3a of the cam member 1, and as shown in FIGS. Until the stopper wall portion 9 is restricted, the cam member 1 is forcibly turned while being pressed leftward in the drawing. Then, as shown in FIG. 7E, the pin member P comes into contact with the second guide wall 3b and is guided into the inlet 2a of the cam groove 2. At this point, the pin member P presses the second guide wall portion 3b in its own traveling direction, so that the cam member 1 is slightly turned rightward in the figure as shown in FIG. . Therefore, at this point, if the pressing operation on the moving body B is released at this point, the moving body B
Is retracted by its own biasing spring pressure, thereby causing the pin member P to lock into the lock portion 2 of the cam groove 2 as shown in FIG.
b, the moving body B is securely locked at the closed position in the housing H. In addition, when the pin member P is locked to the lock portion 2b, a clicking sound does not occur as in the related art because the torsion spring is not used.

Further, when the moving body B is further pushed into the housing H in this state, the pin member P is disengaged from the lock portion 2b of the cam groove 2, and as shown in FIG. (3), the third guide wall 3d is pressed in the traveling direction at the same time as it comes into contact with the third guide wall 3d. As shown in (1), the cam member 1 is forcibly turned further rightward in the drawing until the stopper wall portion 8 is restricted. Therefore, at this point, if the pressing operation on the moving body B is released, the pin member P automatically separates from the cam member 1 through the inclined outlet 2c of the cam groove 2, so that the moving body B has its own. It is possible to protrude from the opening of the housing H to the outward open position by the urging spring pressure. In addition, when the lock is released, no clicking sound is generated for the same reason. When the pin member P passes through the inclined outlet 2c, the free end of the cam member 1 is allowed to swing downward due to the bending of the compression coil spring 6, as shown in FIG. After the passage, the horizontal posture of the cam member 1 is maintained again by the spring pressure of the compression coil spring 6.

In the embodiment described above, the cam member 1 is provided on the housing H side and the pin member P is provided on the moving body B side. However, the present invention is not limited to this. It is needless to say that the same operation and effect can be obtained even if the pin member P is provided on the H side and the cam member 1 is provided on the moving body B side. The provision in the state is optional depending on the implementation. Further, in the embodiment, the compression coil spring 6 is used together with the block portion 7 as a means for maintaining the posture of the cam member 1, but the compression coil spring 6 moves the cam member 1 in a predetermined turning direction. Since it does not perform the urging function, a spring means such as a leaf spring material can be used instead of the compression coil spring 6.

[0014]

As described above, the present invention is characterized in that the cam member is forcibly turned in a predetermined direction only by the moving force of the pin member interlocking with the moving body. The cam member can be pivotally and swingably mounted simply by inserting the tip of the rotating shaft portion into the bearing portion without performing complicated work associated with the use of the spring. The operation is greatly simplified, and the cam member is maintained in a predetermined posture by the action of the posture maintaining means, so that there is no fear that operation will be hindered. In addition, the elimination of the torsion spring makes it possible to reduce the number of parts, but when the pin member is locked in the lock portion of the cam groove or when the cam member returns to the standby position. In addition, since the unpleasant operation noise unlike the related art is not generated, the fear that the sense of quality is lost can be eliminated. Moreover, the lock device of the present invention can be applied to any push-open type moving body, so that its use range is extremely large.
