Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a side lock device for a storage body such as a glove box which is openably and closably attached to an instrument panel side of an automobile.

[0002]

2. Description of the Related Art As a conventional side lock device of this type,
There is one disclosed in JP-A-4-60079. Although not specifically shown, the conventional side lock device rotatably supports a pair of left and right link levers in a housing fixed to the glove box side so that upper and lower end sides of the left and right link levers are supported. In addition to providing a pair of latches that go in and out of the lock holes formed in the instrument panel,
A tension coil spring is provided between the lower ends of the left and right link levers to urge the left and right latches in a direction to always engage the lock holes.

When the glove box is closed, the tips of the latches provided on the upper ends of the left and right link levers are engaged in the corresponding left and right lock holes on the instrument panel side. , The glove box is locked in its closed position.When releasing this locked state and opening the glove box, the swinging operation of the operating handle opposes the middle part of the pair of left and right link levers. If you push down each protruding arm provided against the biasing spring pressure of the tension coil spring, the left and right link levers rotate in the direction opposite to the biasing direction, and the tip of the latch moves from the lock hole. Since it is retracted, this makes it possible to move the glove box in the opening direction.

[0004]

Therefore, in the conventional side lock device, there is an advantage that the locked state and the unlocked state can be easily obtained on both sides of the glove box, but on the other hand, the glove box and If it is necessary to change the protruding / retracting amount of the latch on the left and right sides due to the shape setting of the instrument panel, the length of the latch is of course, but the size of the link lever and housing should be adjusted accordingly. Since it will have to be changed, the storage space of the glove box itself may be limited.

[0005]

The present invention was developed in order to effectively solve the problems faced by such a conventional side lock device. The invention according to claim 1 provides a support body with a storage body. A housing for opening and closing is provided, and a housing for movably holding a pair of left and right latches is provided on the side of the storage body,
By biasing each of the left and right latches in the direction of the lock hole formed on the support body side by the biasing spring pressure, the swinging operation of the operation handle
In a side lock device for a storage body configured to retreat the front end portions of the left and right latches from a lock hole on the support body side against a biasing spring pressure, the side lock device is rotated by a rotational force obtained from a swinging operation of an operation handle. A cam groove formed on either one of the rotation means or the latch and a projection moving along the groove edge of the cam groove on the other side, and a cam accompanying rotation of the rotation means. By the action of the groove and protrusion, the tip of each left and right latch is retracted from the lock hole on the support side.

According to the second aspect of the invention, on the basis of the first aspect, a configuration is adopted in which the cam grooves are formed in a pair of left and right latches.

According to a third aspect of the invention, on the premise of the first aspect, the rotating means has a cylindrical shape and is fixed to the operation handle side, and a protrusion is formed on the inner peripheral surface of the rotating means. , Forming a cam groove in the semi-cylindrical portion, defining a cylindrical shape in each of the opposing semi-cylindrical portions, and urging each of the left and right latches therein in the direction of the lock hole on the support side. A structure in which biasing means is arranged is adopted.

Therefore, in the invention described in claim 1, when it is necessary to change the protruding / retracting amount of the latch on both the left and right sides by setting the shape of the supporting body and the containing body, the conventional method is used. In addition, it is extremely rational because it is possible to meet the request only by changing the lengths of the cam groove and the latch without significantly changing the device itself. Moreover, it is not necessary to change the size of the housing because only the length is changed with respect to the horizontal axis direction.

According to the second aspect of the invention, since it is possible to deal with the problem by changing only the latch having the cam groove, it becomes more rational. In the invention according to claim 3, since only one urging means is sufficient, space saving can be expected, and the protrusion engages with the cam grooves of the left and right latches inside the cylindrical rotating means. Therefore, the stable engagement between the protrusion and the cam groove can be guaranteed.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the preferred embodiments shown in the drawings. The side lock device according to the first embodiment is also attached to an instrument panel of an automobile so as to be openable and closable. It is intended for a glove box to be used, and it is premised that the box body is rotatably supported by a space in the instrument panel.

Further, in the first embodiment, FIG.
As shown in FIG. 1, a through hole 1 having a bearing piece 2 at the hole edge is bored in the central portion of the front wall of the box body B, and the through hole 1
A base portion 11 of a rotary shaft 6A described later from the front side thereof
A pair of left and right latches 4 on the back side of the front wall, and two compression coil springs 5 and a rotary shaft 6A for urging the left and right latches 4 while supporting the operation handle 3 which is screwed to
The housing 7 for housing is integrally fixed via screws (not shown) or the like.

The left and right latches 4 are integrally formed of synthetic resin and each has a rectangular rod-like body having a tapered surface 4a at its tip, and a pin 10 protruding at its rear end via an enlarged flange 8. The cylindrical portion 9 having the
A tip portion is projected outward from a side hole 7a of a housing 7 described later, and a tubular portion 9 is slidably inserted into a tubular portion 12 of a rotary shaft 6A, which will be described later. The biasing spring pressure of the compression coil spring 5 mounted on the instrument is biased toward the lock hole formed on the instrument panel side.

The rotating shaft 6A, which serves as a rotating means, is integrally molded of synthetic resin and has a base portion 11 for fixing the operation handle 3, and a pair of base portions 11 connected to both ends of the base portion 11 via shaft portions 13. And a pair of tubular portions 12
On the other hand, by forming the cam groove 14 that engages the pin 10 provided on the tubular portion 9 of each of the latches 4, the rotary shaft 6A itself is rotated by the rotational force obtained from the swinging operation of the operation handle 3. By doing so, the pin 10 is moved along the groove edge of the cam groove 14, and the left and right latches 4 are retracted against the biasing spring pressure of the compression coil spring 5.

The cam groove 14 has a symmetrical shape on the left and right sides, and when the pin 10 is located on the tip end side of the groove edge of the cam groove 14, the tip ends of the left and right latches 4 respectively. The pin 10 protrudes in the direction of the lock hole on the instrument panel side, and conversely, the pin 10 moves along the groove edge of the cam groove 14 and is located on the rear end side of the groove edge while the rotary shaft 6A rotates. Time
The left and right latches 4 are retracted from the lock holes on the instrument panel side. In the first embodiment, however, the escape groove 15 communicating with the cam groove 14 is continuously formed, and then assembled. The pin 10 provided on each of the left and right latches 4 is moved in the escape groove 15 at the time and the like.

The housing 7 is integrally molded of synthetic resin, and a block 17 is provided at the center of the housing 7.
A double torsion spring 18 that abuts against the base portion 11 of the rotary shaft 6A and biases the operating handle 3 to the non-operating state without rattling is attached to each side 7, and the left and right latches 4 are provided on both sides thereof.
The side hole 7a having a rectangular shape is formed so as to pass through the tip of the.

Therefore, when the box body B is in the closed state under the side lock device having such a structure, it is mounted in the cylindrical portion 12 of the rotary shaft 6A as shown in FIGS. Due to the biasing spring pressure of the compression coil spring 5, the tip ends of the pair of left and right latches 4 pass through the side holes 7a of the housing 7 and the rectangular through holes Ba formed on both side walls of the box body B,
Engage in the lock hole Pa of the instrument panel P,
The box body B is locked at the closed position. In this closed state, the latch 4 in the form of a square rod is provided with the square side hole 7a and the square through hole B described above.
Since it is fitted to a, the left and right latches 4
Will be restricted from rotating.

Then, the locked box body B
When the operation handle 3 is rotated in the opening direction, as shown in FIGS. 4 and 5, when the operation handle 3 is oscillated against the urging spring pressure of the double torsion spring 18, the rotation shaft is interlocked with this. Since the entire 6A rotates, the cam groove 1 on the rotating shaft 6A side
The pin 10 that engages with each other 4 moves to the rear end side of the cam groove 14 along the corresponding groove edge of the cam groove 14 so that the left and right latches 4 are biased by the compression coil spring 5. It will be forced to retreat.

Then, as the left and right latches 4 are forcibly retracted, the tip portions of the left and right latches 4 are also retracted from the corresponding lock holes Pa of the instrument panel P.
Although the box body B is allowed to automatically rotate to the open position, if the operation of the operation handle 3 is released after the box body B has rotated in the opening direction, 2
The pin 10 moves in the cam groove 14 toward the tip end side along the groove edge thereof by the biasing spring pressure of the compression coil spring 5, so that the rotary shaft 6A rotates in the opposite direction and, at the same time, the operation handle 3 The urging spring pressure of the double torsion spring 18 causes the operation to return to the non-operating state without backlash. The tip portions of the left and right latches 4 are also moved by the pin 10 in the cam groove 14, and the biasing spring pressure of the compression coil spring 5 causes the lock hole P to be locked again.
It projects in the a direction.

On the contrary, when the opened box body B is returned to the closed state, the box body B is rotated to the vacant side of the instrument panel P as it is, but at this time, the lock hole Pa The tapered surfaces 4a provided at the tips of the left and right latches 4 protruding in the direction come into contact with the surface of the instrument panel P in which the lock hole Pa is formed, and the left and right latches 4 are provided with the compression coil springs 5. The box body B moves in a retracted manner against the biasing spring pressure and again engages with the corresponding lock hole Pa, so that the box body B is in the closed lock state. In this case, regardless of the operation of the operation handle 3, only the left and right latches 4 only retreat within the cylindrical portion 12 of the rotary shaft 6A, so that the operation handle 3 itself is placed in the operating state. Since it never happens, it also looks good.

Therefore, under the side lock device according to the first embodiment, the instrument panel P serving as a support is provided.
If it is necessary to change the protruding / retracting amount of the latch 4 on both the left and right sides by setting the shape of the box body B that is a storage body or a storage body, the cam can be changed without drastically changing the device itself as in the conventional case. The request can be met simply by changing the lengths of the groove 14 and the latch 4, which is extremely rational and the length in the horizontal axis direction can be changed. No need to change.

Next, the side lock device according to the second embodiment will be described. The second embodiment also basically follows the above-described first embodiment. The difference is that a cam groove 14 is formed on the side of the pair of left and right latches 4 and a pin 10 that moves inside the cam groove 14 along its groove edge is provided on the side of the rotary cylinder 6B that serves as a rotating means. It is what you have done. Further, in the second embodiment, the double torsion spring 18 for urging the operation handle 3 in the non-operation state is not provided.

This will be described in detail. For each of the left and right latches 4, as shown in FIGS. 6 and 7, a round rod-shaped body having a longer length dimension than that of the first embodiment is used. A semi-cylindrical guide portion 19 is integrally connected to the rear end of the semi-cylindrical guide portion 19 to form a cam groove 14 on the front surface side of the semi-cylindrical guide portion 19, and a compression coil spring is provided inside the guide portion 19. 5, the semi-cylindrical guide portions 19 facing each other define a cylindrical shape, and the left and right latches 4 are locked inside the instrument panel P side. One compression coil spring 5 that urges in the direction of the hole Pa is arranged. In addition to the relief groove 15 of the first embodiment, the cam groove 14 of the second embodiment has
A cutout groove 16 for introducing the pin 10 into the cam groove 14 is formed.

Further, as shown in FIGS. 6 and 8, a semi-cylindrical guide member 19 defining the above-mentioned cylindrical shape can be inserted into the rotary cylinder 6B serving as a rotating means. The pair of pins 10 that are formed integrally with the operation handle 3 and are engaged with each other in the cam grooves 14 via the notch grooves 16 are provided in the inner peripheral surface of the box handle B so as to face each other. It is rotatably supported together with the operation handle 3 in the through hole 1 formed in the front wall through a holding plate 22 fixed to a bearing portion 21 provided on the back side of the box body B. It is composed. However, it is also possible to mold the rotary cylinder 6B separately from the operation handle 3 and fix the rotary cylinder 6B to the operation handle 3 side later.

Incidentally, the housing 7 in the second embodiment
Is formed into a size and shape capable of accommodating the pair of left and right latches 4 and the rotary cylinder 6B, and has notched side holes 7a formed on both sides thereof for inserting the tip portions of the left and right latches 4 therein. Therefore, under the second embodiment, the rectangular portions 23 are formed at the boundaries between the left and right latches 4 and the guide portions 19, and the rectangular concave portions 24 are formed on both sides of the bearing portion 21.
The rotation of each of the left and right latches 4 is restricted by the insertion of 3/24. Therefore, the through hole Ba on the side of the box body B is round.

Therefore, in the case where the pair of left and right latches 4 are assembled in the rotary cylinder 6B integrated with the operation handle 3 under the side lock device having such a structure, one compression coil spring 5 is interposed. Then, the left and right latches 4 are inserted from the guide portion 19 side into the rotary cylinder 6B while being overlapped with each other, and when the rotary cylinder 6B is rotated, the pair of pins 10 projecting inside the rotary cylinder 6B are obtained. Will be guided into the cam groove 14 from the corresponding notch groove 16 and the left and right latches 4 will be supported by the rotary cylinder 6B so as to be retractable.

When the box body B is in the closed state, as shown in FIG. 9, the biasing force of the compression coil spring 5 mounted inside the guide portion 19 of each latch 4 defined by the cylindrical shape. Due to the spring pressure, the tips of the pair of left and right latches 4,
Through the cutout side hole 7a of the housing 7 and the round through hole Ba formed on both side walls of the box body B, the lock hole Pa of the instrument panel P is engaged and the box is closed at the closed position. Body B is locked. In this case, as shown in FIG. 10, the operation handle 3 is in a non-operation state.

Further, when the locked box body B is rotated in the opening direction, when the operation handle 3 is rocked as shown in FIG. 11, the rotary cylinder 6B is rotated in conjunction with this. Therefore, the pin 10 on the rotary cylinder 6B side moves along the corresponding groove edge of the cam groove 14, and as shown in FIG. 12, the left and right latches 4 are biased by the compression coil springs 5. Will be forced to retreat against.

Then, as the left and right latches 4 are forcibly retracted, the tip portions of the left and right latches 4 are also retracted from the corresponding lock holes Pa of the instrument panel P.
Although the box body B is allowed to automatically rotate to the open position, when the operation of the operation handle 3 is released after the box body B has rotated in the opening direction, the compression coil spring 5 is attached. The pin 10 is moved into the cam groove 14 by the bias spring pressure.
By moving the inside in the opposite direction, the tip ends of the left and right latches 4 are projected again in the lock hole Pa direction by the biasing spring pressure of the compression coil spring 5, and at the same time, the rotary cylinder 6B also rotates in the opposite direction.
The operation handle 3 is returned to the non-operation state.

On the contrary, when the opened box body B is returned to the closed state, the box body B is rotated to the vacant side of the instrument panel P as it is, but at this time, the lock hole Pa The left and right latches 4 protruding in the respective directions are provided with tapered surfaces 4a,
The left and right latches 4 move backward while resisting the biasing spring pressure of the compression coil spring 5, and again engage with the corresponding lock holes Pa by coming into contact with the instrument panel P surface on which is formed. As a result, the box body B is placed in the closed lock state. In this case, as in the first embodiment, regardless of the operation of the operation handle 3, only the left and right latches 4 only retreat into the rotary cylinder 6B, and therefore the operation handle 3 itself. The appearance is also improved because it is not left in the operating state.

Therefore, even under the side lock device according to the second embodiment, the instrument panel P serving as a support body is provided.
When it is necessary to change the protruding / retracting amount of the latch 4 on both the left and right sides due to the shape setting of the box body B that is a storage body, the device itself does not need to be significantly modified as in the conventional case. The requirement can be met simply by changing the lengths of the cam groove 14 and the latch 4, which is extremely rational and the length in the horizontal axis direction can be changed. There is no need to change the size.

Moreover, in particular, in the second embodiment, since the cam groove 14 is formed on the side of the latch 4, only the latch 4 needs to be changed, which is more rational. Since only one compression coil spring 5 is required as the biasing means, space saving can be expected, and the pin 10 has the left and right latches 4 inside the rotary cylinder 6B having a cylindrical shape.
Since it is engaged with the cam groove 14, the stable engagement state of the pin 10 and the cam groove 14 can be guaranteed.

[0032]

As described above, according to the present invention, by adopting the above-described structure, when it is necessary to change the protruding / retracting amount of the latch on both the left and right sides by setting the shape of the support and the storage, This is extremely rational because it is possible to meet the request by simply changing the lengths of the cam grooves and the latches without significantly modifying the device itself as in the conventional case. Moreover, it is not necessary to change the size of the housing because only the length is changed with respect to the horizontal axis direction.
