[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a floating lock for holding a floating portion raised from a chassis by an elastic member and an anti-vibration damper when a disk is inserted in order to prevent sound skipping during disk reproduction in a vehicle disk device. It concerns the device.

[0002]

2. Description of the Related Art In a car-mounted CD player, when a disk is reproduced, sound skips occur when vibration of a car is transmitted to a turntable or a pickup. For this reason, the in-vehicle CD player has a floating portion supported by an elastic member and an anti-vibration damper on a chassis thereof, and a turntable and a pickup are attached to the floating portion. With this configuration, the vibration transmitted from the vehicle to the chassis is absorbed by the elastic member and the vibration damper, and is less likely to be transmitted to the turntable and the pickup. However, with such a configuration, the position of the floating portion in the chassis is unstable, and
When the disc is inserted into the D player, the disc may hit the pickup or the turntable, and the disc surface may be damaged, or the disc may not be set. Therefore, a CD player mounted on a vehicle is conventionally provided with a floating lock device, and by using this device, when inserting a disc, several positions around the floating portion are held and positioned, thereby preventing an accident of damaging the disc. When the disc is reproduced, the holding portion is released to prevent the vibration of the car from being transmitted through the chassis.

[0003] Such a floating lock device is
Conventionally, it is composed of a plate provided around the floating part and a motor as a power source, and this plate moves between an engaging position engaging with the floating part and a releasing position separating from the floating part by rotation of the motor. It is supposed to. Therefore, when inserting the disk, if the plate is moved to the engagement position,
Since the turntable provided on the floating portion is held at a predetermined position, the disc can be set without damage to the disc. At the time of disk reproduction, if the plate is moved to the release position, only the elastic member and the vibration damper support the floating portion. Therefore, the vibration of the vehicle is absorbed by the elastic member and the vibration damper, and it is difficult for the vibration to be transmitted to the pickup provided in the floating portion, so that sound skipping can be prevented.

An example of such a conventional floating lock device will be described below with reference to the drawings. In addition,
The upper part in the figure is the rear, and the lower part is the front. That is, as shown in FIG. 6, the floating portion 2 is provided inside the chassis of the CD player. As shown in FIG. 7A, an auxiliary plate 1a is provided on the right side of the floating portion 2, and a shift plate 3 is provided on the auxiliary plate 1a so as to be slidable back and forth. A lock claw 3 a is provided behind the shift plate 3. On the other hand, a front lock mechanism is provided in front of the floating portion 2. The front lock mechanism is adapted to be engaged and disengaged in front of the floating portion 2 in conjunction with the forward and backward movement of the shift plate 3. Further, a holding portion 1b is provided behind the left side surface of the side lock plate 1 slidably provided back and forth. Therefore, the structure is such that the floating portion 2 is inserted between the lock claw 3a and the front lock mechanism and the holding portion 1b.

The members constituting the floating lock device as described above will be described in detail below. That is, a holding portion 1b protruding rightward is provided behind the side lock plate 1. A floating portion 2 of a rectangular plate is provided on a bottom surface of a chassis (not shown). A groove is formed on the left rear side of the floating portion 2, and serves as a rear lock portion 2a with which the holding portion 1b is engaged. The floating section 2 is provided with a spindle motor, a turntable, a pickup feed mechanism, and a clamper, which are members for reproducing a disk. And
The floating portion 2 is supported by a spring or a vibration damper so as to float from the bottom of the chassis. In addition, there are two left and right bent portions in front of the floating portion 2 to form a left lock portion 2d and a right lock portion 2e. Further, the right side surface of the floating portion 2 is vertically bent, and a rear end portion of the bent portion is provided with FIG.
As shown in (B), a Y-shaped lock groove 2b is provided.

A rectangular auxiliary plate 1a is fixed to the bottom of the chassis on the right side of the floating portion. The right side of the auxiliary plate 1a is a supporting portion 1c which is raised in the vertical direction, and is provided with a pin 1d protruding rightward. A rectangular shift plate 3 is provided on the right side of the support 1c. The shift plate 3 is slidable in the front-rear direction by the operation of a motor serving as a moving unit. The shift plate 3 has a horizontally long hole, and the pin 1d of the support portion 1c is exposed from the hole. A flat locking claw 3 a protruding toward the right side surface of the floating portion 2 is fixed to a rear end portion of the shift plate 3. The lock claw 3a is engaged with a lock groove 2b provided on the right side surface of the floating portion 2. Further, a pin 3b is provided on the right surface of the shift plate 3. The pin 3b is located forward of the pin 1d of the support 1c, and a torsion spring 4 is engaged between the two pins. That is, as shown in FIG. 7 (B), the torsion spring 4 which is a torsion coil spring with both legs of the coil extended is slightly closed so that a return force to return to the outside is exerted, and one of the legs is moved. The pin 3b is engaged, and the opposite foot is engaged with the pin 1d.

On the other hand, a front lock mechanism is provided in front of the floating section 2. As shown in FIG. 6, the front lock mechanism includes four plates that are rotatably connected to each other between the side lock plate 1 and the front of the shift plate 3. The right two of them
The left side link 5 to which the movement of the shift plate 3 is transmitted
a, the right link 5b, and the left two are a left lock plate 6a and a right lock plate 6b. Each of the links 5a and 5b and the plates 6a and 6b are rotatable about an axis provided at a substantially central portion thereof. One end of the right link 5b is rotatably provided in front of the shift plate 3, and the opposite end is rotatably provided at one end of the left link 5a.

[0008] The opposite end of the left link 5a is rotatably provided at one end of the right lock plate 6b. The opposite end of the right lock plate 6b is rotatably provided at one end of the left lock plate 6a. Further, the opposite end of the left side lock plate 6a is provided rotatably in front of the left side surface of the side surface lock plate 1. Pawls 6c and 6d are provided behind the right lock plate 6b and the left lock plate 6a, respectively, and are engaged with the inside of the left lock portion 2d and the right lock portion 2e of the floating portion 2, respectively.

The operation of the conventional example having the above configuration is as follows. That is, when the disc is inserted, the return force of the torsion spring 4 causes the lock groove 2 b
The lock pawl 3a engaged with the hook 6 is urged forward, and the pawls 6c, 6
d is engaged with the left locking portions 2d and 2e, and the holding portion 1
Since b is engaged with the rear lock portion 2a, the floating portion is held. Next, when the shift plate 3 is slid backward by operating the motor, the lock claw 3a is disengaged from the lock groove 2b, and the torsion spring 4 rotates. At the time of disc reproduction, the shift plate 3 is urged rearward by the return force of the torsion spring 4, and the lock claw 3a is positioned rearward. On the other hand, when the shift plate 3 slides rearward, the right link 5b rotates counterclockwise and the left link 5a rotates clockwise as shown in FIG. When the left link 5a rotates clockwise, the right lock plate 6b rotates counterclockwise, and the left lock plate 6a rotates clockwise. Then, the side lock plate 1 moves rearward. Then, the claws 6c and 6d engaged with the inside of the left and right lock portions move so as to approach each other, and come off from the left lock portion 2d and the right lock portion 2e. Further, the holding portion 1b is separated from the rear lock portion 2a.

The operation of such a conventional example will be described in detail below with respect to three states, that is, a locked state when the disk is inserted, a spring displaced state when the shift plate is moved, and an unlocked state when the disk is reproduced. That is, in the locked state, as shown in FIGS. 7A and 7B, the torsion spring 4 is provided so as to exert a returning force to return to the outside, and the pin 3b is moved by the returning force. Forward, the pin 1d is biased rearward. At this time, since the pin 3b is provided on the shift plate 3 and the pin 1d is provided on the support portion 1c of the auxiliary plate 1a, the shift plate 3 is urged forward and the auxiliary plate 1a is urged rearward. . Although the auxiliary plate 1a is fixed to the chassis, the shift plate 3 is provided so as to be slidable forward and backward, so that only the shift plate 3 slides forward, and a lock provided at the rear end of the shift plate 3 is provided. The claw 3a is biased forward. Since the lock claw 3a is engaged with the lock groove 2b at the rear of the floating portion 2, it urges the floating portion 2 forward. On the other hand, claws 6c and 6d provided on the left and right lock plates are engaged with the inside of the left and right lock portions on the front surface of the floating portion 2, as shown in FIG. 1b is engaged with the rear locking portion of the floating portion 2, so that the floating portion 2 is held at three positions: left, front, and right.

Next, in the spring displacement state,
As shown in FIGS. 9A and 9B, the shift plate 3 slides rearward by the operation of the motor. Then, the lock claw 3a comes off the lock groove 2b, and the floating portion 2 is released. At this time, the torsion spring 4 rotates about the pin 1d at one end thereof, and the pin 3b at the opposite end moves below the pin 1d.

Further, in the unlocked state, FIG.
As shown in FIGS. 0 (A) and (B), the shift plate 3 slides further backward. Then, the torsion spring 4 rotates about the pin 1d, and the pin 3 at the opposite end is rotated.
b moves behind the pin 1d. Therefore, since the return force of the torsion spring 4 acts in a direction opposite to the locked state, the pin 3b is urged rearward, and the shift plate 3 and the lock claw 3a are positioned rearward of the chassis. On the other hand, when the shift plate 3 slides rearward, the pawls 6c and 6d are disengaged from the left and right lock portions in front of the floating portion 2 and the holding portion 1b is moved from the lock portion 2 as described above.
b. Therefore, the floating part 2 is released.

[0013]

However, the above-mentioned conventional floating lock device has the following disadvantages. That is, since the shift plate 3 slides back and forth, it is desirable that the urging force always acts in a direction (horizontal direction) parallel to the chassis bottom surface. However, since the biasing force is obtained by the return force of the torsion spring 4 engaged with the pins 1a and 3b, the biasing force and the biasing direction tend to vary. In other words, since the torsion spring 4 opens and closes in a circular locus around its coil portion, the direction in which the restoring force acts is not an accurate horizontal direction. Further, when the shift plate 3 moves, the torsion spring 4 rotates around the portion engaged with the pin 1d, so that the direction in which the return force of the torsion spring 4 works changes, and the biasing force in the horizontal direction varies. Easy to occur. Therefore, an extra force is applied in a direction other than the horizontal direction, and it becomes difficult to smoothly slide the shift plate 3.

The horizontal biasing force of the torsion spring 4 increases as the positions of both ends become horizontal, and the horizontal biasing force decreases as the positions of both ends approach the vertical direction. In the locked state and the unlocked state, both ends of the torsion spring 4 approach horizontal, and when the spring is displaced, the torsion spring 4
Ends approach vertically. Therefore, the operating load applied to the motor driving the shift plate 3 approaches the maximum in the locked state and the unlocked state, and approaches the minimum when the spring is displaced. Therefore, an extreme load change occurs, which is disadvantageous for the durability of the motor.

Since the coil portion of the torsion spring 4 is short, the wire of the material must be thickened in order to obtain a certain or more return force. Therefore, the production efficiency is poor when producing. In addition, the shape of the torsion spring 4 is thick in the left-right direction, and two long legs extend in different directions, so that the occupied area in the CD player for operation is wide. In addition, since the device rotates when the spring is displaced, it is disadvantageous for downsizing the device.

Further, in order to securely hold the floating portion 2, it is desirable to have three or more holding portions. Therefore, in the conventional example, the holding is performed at the three positions of left, front, and right. However, since the front lock mechanism as the holding means is complicated, it is disadvantageous for simplification and downsizing of the device.

The present invention has been proposed in order to solve the problems with the prior art as described above, and its object is to
Bias for unlocking when the lift plate moves
Movement due to unevenness in the biasing force of the means
The present invention provides a floating lock device capable of securely holding a floating portion without causing trouble .

[0020]

The operation of the present invention having the above configuration is as follows. That is, according to the floating lock device of the first aspect, when the disk is inserted, the first engagement means is engaged with the floating portion. When the shifting means is operated to slide the shift plate, the tension coil spring or the compression coil spring expands or contracts, so that the first engaging means is urged in the direction of movement of the shift plate by the return force. When the shift plate is further slid during reproduction of the disc, the first engaging means is rotated by the action of the cam means and the restoring force of the tension coil spring or the compression coil spring, and comes off the floating portion. Then, the first engagement means is provided by the tension coil spring or the compression coil spring.
It is maintained in either the engaged position or the released position.

Further, according to the floating lock device of the present invention, when the disk is inserted, the second engaging means provided on the shift plate is engaged with the floating portion. Therefore, the floating portion is held by the first engagement means and the second engagement means. When reproducing the disc, when the shift plate is moved, the cam means functions to engage the first engaging means with the cam means.
The joint is moved in a direction opposite to the moving direction of the second engagement means.
Thus , the floating part is released.

On the other hand, the drive lock plate 8 is
As shown in the figure, an inverted triangular plate is provided at its left end with an engaging portion 8 which engages with the first groove 2c of the floating portion 2.
a is provided. This drive lock plate 8
Are the first cam groove 10 and the second cam groove 1 of the shift plate 3.
1 and the drive lock plate 8
Is fixed to the auxiliary plate 1a through the first cam groove 10. Therefore, the drive lock plate 8 is rotatable around the rotation shaft 8b. Drive lock plate 8
A guide pin 8c protruding downward is provided at the right end of the lower surface. The guide pin 8c is provided in the second cam groove 11
Is engaged. Further, a second engaging claw 12 is provided on the right shoulder of the drive lock plate 8.
Both ends of the tension spring 13 are engaged with the engagement claws and the first engagement claws 9 of the shift plate 3. The tension spring 13 is a cylindrical tension coil spring.

The drive lock plate 8 is the first engaging means, the second cam groove 11 and the guide pin 8c are the cam means according to the first and second aspects, and the lock claw 3a is the first aspect. Item 2 is a second engaging means.

(2) Operation of the Embodiment The operation of the floating lock device having the above-described configuration will be described below in detail for the lock state, the spring displacement state, and the lock release state, similarly to the conventional example.

(A) Locked State As shown in FIGS. 1A, 1B and 2, a lock claw 3 a of the shift plate 3 is engaged behind the second groove 2 c ′,
Since the engaging portion 8a of the drive lock plate 8 is engaged with the first groove 2c and the holding portion 1b of the side lock plate 1 is engaged with the rear lock portion of the floating portion 2 as in the conventional example. The floating part 2 is held.

(B) Spring Displacement State The motor is operated to rotate the pinion gear. Since the gear groove 7c is engaged with this pinion gear, the rack 7 slides forward. This rack 7 is shown in FIG.
As shown in (B), the shift plate 3 is mounted so as to overlap with the pin 3b, and the shift plate 3 is provided so as to be slidable back and forth. Therefore, when the rack 7 moves forward, the shift plate 3 is also moved. Move forward. At this time, since the hole 7a is horizontally long, the contact surface between the rack 7 and the shift plate 3 slips by the length of the hole 7a, and the operation timing of the rack 7 and the shift plate 3 is slightly shifted. Since the hook 7b of the rack 7 and the hook 3d of the shift plate 3 are connected by a spring 14, the spring 14 serves as a cushion, and the movement of the rack 7 is transmitted to the shift plate 3 gently.

Further, when the shift plate 3 slides forward as described above, as shown in FIG.
First cam groove 10 and second cam groove 1 behind shift plate 3
The first and first engagement claws 9 move forward. Then, the first
The tension spring 13 engaged between the engagement claw 9 and the second engagement claw 12 extends. Since the second engagement claw 12 is provided on the right shoulder of the drive lock plate 8, when the tension spring 13 extends, the drive lock plate 8 is urged rightward and forward.

(C) Unlocked State As shown in FIGS. 4A and 4B, when the shift plate 3 moves further forward, the second cam groove 11 moves forward, and the guide of the drive lock plate 8 is guided. The pin 8c fits into the bent portion of the second cam groove 11 and shifts to the right. The drive lock plate 8 is biased rightward and forward by the tension spring 13 and is provided so as to be rotatable around the rotation shaft 8b . It comes off the groove 2c . On the other hand, the lock claw 3a of the shift plate 3 also moves forward and comes off from the rear of the second groove 2c '. Further, for example, the side lock plate 1
Also recedes by an appropriate method, and the lock of the rear lock portion 2a is released. Therefore, the floating part 2 is released.

(3) Effects of the Embodiment The effects of the present embodiment as described above are as follows.
That is, since the urging force of the drive lock plate 8 holding the floating portion 2 is obtained by the tension spring 13 of the tension coil spring, the urging force and the urging direction are stable. In other words, the tension spring 13 exerts a force only in the direction of the center axis of the coil.
The direction in which the biasing force works is the horizontal direction. When the guide pin 8c is engaged with the bent portion of the second cam groove 11, the tension spring 13 is slightly inclined, but the inclination angle is small.
The biasing force becomes uniform. Therefore, the shift plate 3 can be slid smoothly.

Since the tension spring 13 only expands and contracts in the horizontal direction, there is no extreme load change.
The load change on the motor is small. Since the tension spring 8 has a long coil portion, the selection range of the set weight is wide, and the production efficiency by the automatic spring winding device is good. Further, the area of the tension spring 13 occupying the inside of the CD player is small and its position is hardly changed, which is advantageous for downsizing of the apparatus.

Further, the mechanism as shown in FIG. 6 makes it possible to hold three places by the drive lock plate 8, the lock claws 3a and the holding portion 1b (FIG. 6) without using a complicated front lock mechanism. This is advantageous for miniaturization and simplification of the device.

(4) Other Embodiments The present invention is not limited to the above-described embodiments, and specific materials and shapes of each part can be appropriately changed. For example, as shown in FIG.
Even if the first engagement claw 9 is provided at the end of the first engagement claw and the compression coil spring 15 is provided between the first engagement claw 9 and the second engagement claw 12, there is no change in the spring biasing direction. The same effect as in the above-described embodiment can be obtained. That is, when the shift plate 3 slides forward, the compression coil spring 15 contracts. Since the second engagement claw 12 is provided on the right shoulder of the drive lock plate 8, when the compression coil spring 15 contracts, the drive lock plate 8 is urged rightward and forward. Next, when the shift plate 3 moves further forward, the second cam groove 11 moves forward, and the guide pin 8c of the drive lock plate 8 fits into the bent portion of the second cam groove 11 and moves to the right. The drive lock plate 8 rotates clockwise, the engaging portion 8a is disengaged from the first groove 2c, and the floating portion 2 is released.

In the above-described embodiment, the shift plate 3 is provided with the lock claw 3a and the floating portion 2 is provided with the second groove 2c '. It is also possible to provide a second groove and a floating claw to provide a lock claw. The engagement portion 8a of the drive lock 8 and the first groove 2c of the floating portion 2 can be reversed. Further, the first engagement means and the second
The force for urging the engagement means to the engagement position or the release position is not limited to the case where it is obtained by a tension coil spring or a compression spring.
