A coil spring is attached.
[0003]
When the glove box is closed, the leading ends of the latches provided at the upper ends of the left and right link levers are engaged with the corresponding left and right lock holes on the instrument panel side. When the locked state is released and the glove box is opened, it is provided to face the middle part of the pair of left and right link levers by swinging the operation handle. If each projecting arm is pushed down 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, causing the tip of the latch to retract from the lock hole. As a result, the glove box can be moved in the opening direction.
[0004]
[Problems to be solved by the invention]
Therefore, the conventional side lock device has 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, it can be latched by setting the shape of the glove box and the instrument panel. When it is necessary to change the amount of protrusion and depression on both the left and right sides, the length of the latch is of course, but the size of the link lever and housing must be changed accordingly. As a result, the storage space of the glove box itself may be limited.
[0005]
[Means for Solving the Problems]
The present invention was developed in order to effectively solve the problems of such a conventional side lock device. The invention according to claim 1 attaches a storage body to a support body so that the storage body can be opened and closed.

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, if it explains in full detail based on each suitable embodiment which illustrates the present invention, the side lock device concerning a first embodiment is also aimed at the glove box attached to the instrument panel of a car so that opening and closing is possible. Therefore, it is assumed that the box body is pivotally supported so as to be rotatable with respect to the space of the instrument panel.
[0011]
In the first embodiment, as shown in FIG. 1, a through hole 1 having a bearing piece 2 at the hole edge is formed in the central portion of the front wall of the box body B, and the through hole 1 An operation handle 3 that is screwed to a base portion 11 of a rotating shaft 6A, which will be described later, is supported from the front side, while a pair of left and right latches 4 and the left and right latches 4 are biased to the back side of the front wall. The housing 7 that houses the two compression coil springs 5 and the rotary shaft 6A is integrally fixed via screws (not shown) or the like.
[0012]
Each of the left and right latches 4 is formed of a synthetic resin so as to be integrally formed, presents a square rod-like body with a tapered surface 4a at the tip, and a cylinder having a pin 10 protruding from the rear end via an enlarged flange 8. The cylindrical portion 9 is integrally connected so that the tip portion protrudes outward from a side hole 7a of the housing 7 described later, and the cylindrical portion 9 is slidably inserted into the cylindrical portion 12 of the rotating shaft 6A described later. Thus, the biasing spring pressure of the compression coil spring 5 mounted in the cylindrical portion 12 of the rotating shaft 6A is biased in the direction of the lock hole formed on the instrument panel side.
[0013]
A rotating shaft 6A serving as a rotating means is integrally formed of synthetic resin, and a base portion 11 for fixing the operation handle 3 and a pair of cylindrical portions 12 connected to both ends of the base portion 11 via shaft portions 13. A cam groove 14 that engages a pin 10 provided on the cylindrical portion 9 of each latch 4 is formed on the pair of cylindrical portions 12, and is obtained from the swinging operation of the operation handle 3. The rotating shaft 6 </ b> A itself rotates with the rotational force to move the pin 10 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. It is the composition which makes it.
[0014]
The cam groove 14 has a symmetrical shape on the left and right, and when the pin 10 is positioned on the tip end side of the groove edge of the cam groove 14, the tip end of each of the left and right latches 4 is an instrument panel. When the pin 10 moves along the groove edge of the cam groove 14 and is positioned on the rear end side of the groove edge in the process of rotating the rotating shaft 6A, The left and right latches 4 are retracted from the lock holes on the instrument panel side. In the first embodiment, the relief grooves 15 communicating with the cam grooves 14 are continuously formed and assembled. The pin 10 provided on each of the left and right latches 4 is moved in the escape groove 15 at times.
[0015]
The housing 7 is integrally formed of synthetic resin, and a block 17 is provided at the center thereof. The housing 17 abuts against the base portion 11 of the rotating shaft 6A and urges the operation handle 3 in a non-operating state without looseness. The double torsion spring 18 is mounted, and a rectangular side hole 7a is formed on both sides of the double torsion spring 18 so as to pass through the tip portions of the left and right latches 4.
[0016]
Therefore, when the box body B is in the closed state under the side lock device having such a configuration, as shown in FIGS. 2 and 3, the compression coil spring mounted in the cylindrical portion 12 of the rotating shaft 6A. With the biasing spring pressure of 5, the distal ends of the pair of left and right latches 4 are locked to the instrument panel P through the side holes 7a of the housing 7 and the rectangular through holes Ba formed in both side walls of the box body B. The box body B is engaged with the hole Pa and locked at the closed position. In this closed state, the latch 4 having a square rod-like body is fitted in the square side hole 7a and the square through hole Ba, so that the left and right latches 4 rotate. Will be regulated.
[0017]
When the locked box body B is rotated in the opening direction, as shown in FIGS. 4 and 5, the operation handle 3 is swung against the biasing spring pressure of the double torsion spring 18. In conjunction with this, the entire rotating shaft 6A rotates, so that the pin 10 engaged in the cam groove 14 on the rotating shaft 6A side is along the groove edge of the corresponding cam groove 14 and the rear end of the cam groove 14 The left and right latches 4 are forcibly retracted against the urging spring pressure of the compression coil spring 5.
[0018]
Then, due to the forcible retraction of the left and right latches 4, the front ends of the left and right latches 4 also retreat from the corresponding lock holes Pa of the instrument panel P. Thereafter, the box body B automatically rotates to the open position. However, when the operation of the operation handle 3 is released after the box body B is rotated in the opening direction, the pin 10 is moved by the biasing spring pressure of the two compression coil springs 5. By moving in the cam groove 14 along the edge of the cam groove 14 toward the tip, the rotary shaft 6A rotates in the reverse direction, and at the same time, the operating handle 3 is rattled to the non-operating state by the biasing spring pressure of the double torsion spring 18. It will return without. Note that the distal ends of the left and right latches 4 also project in the direction of the lock hole Pa again by the biasing spring pressure of the compression coil spring 5 due to the movement of the pin 10 in the cam groove 14.
[0019]
Conversely, when returning the opened box body B to the closed state, the box body B is rotated as it is toward the empty side of the instrument panel P. At this time, the box body B protrudes in the direction of the lock hole Pa. The taper surface 4a provided at the tip of each of the left and right latches 4 is in contact with the surface of the instrument panel P in which the lock hole Pa is formed. Therefore, the box main body B is put in the closed lock state because it moves into the corresponding lock hole Pa again. In this case, regardless of the operation of the operation handle 3, only the left and right latches 4 are merely retracted in the cylindrical portion 12 of the rotary shaft 6A, so that the operation handle 3 itself is put into an operation state. Since there is nothing, the appearance is also improved.
[0020]
Therefore, under the side lock device according to the first embodiment, it is necessary to change the amount of protrusion and withdrawal of the latch 4 on both the left and right sides by setting the shape of the instrument panel P as a support and the box body B as a storage body. In such a case, it is possible to meet the demand by changing the length of the cam groove 14 and the latch 4 without changing the device itself as in the prior art. In addition, since the length in the horizontal axis direction is changed, there is no need to change the size of the housing 7.
[0021]
Next, the side lock device according to the second embodiment will be described. The second embodiment basically follows the first embodiment described above. This time, the cam groove 14 is formed on the side of the pair of left and right latches 4 and the pin 10 that moves in the cam groove 14 along the edge of the cam groove 14 is provided on the side of the rotating cylinder 6B as the rotating means. It is. Further, in the second embodiment, the double torsion spring 18 that urges the operation handle 3 to the non-operation state is not provided.
[0022]
This will be described in detail. For each of the left and right latches 4, as shown in FIGS. 6 and 7, a round bar having a longer dimension than that of the first embodiment is formed, A guide portion 19 having a semi-cylindrical shape is integrally connected to the portion, a cam groove 14 is formed on the surface side of the semi-cylindrical guide portion 19, and an end of the compression coil spring 5 is provided inside the guide portion 19. Are formed in a cylindrical shape by the opposing semi-cylindrical guide portions 19, and the left and right latches 4 are arranged in the lock hole Pa direction on the instrument panel P side. It is the structure which arrange | positions the one compression coil spring 5 urged | biased to. In the cam groove 14 in the second embodiment, a notch groove 16 for introducing the pin 10 into the cam groove 14 is formed in addition to the escape groove 15 in the first embodiment.
[0023]
Further, as shown in FIGS. 6 and 8, the rotating cylinder 6B serving as the rotating means has a cylindrical body of a size capable of inserting the semi-cylindrical guide portions 19 that define the cylindrical shape. A pair of pins 10 formed integrally with the operation handle 3 and engaged with each cam groove 14 via the notch groove 16 are provided on the inner peripheral surface of the operation handle 3 so as to face each other. It is configured to be rotatably supported together with the operation handle 3 in the through-hole 1 formed through a presser plate 22 fixed to a bearing portion 21 provided on the back side of the box body B. ing. However, the rotary cylinder 6B can be formed separately from the operation handle 3, and the rotary cylinder 6B can be fixed to the operation handle 3 side later.
[0024]
The housing 7 in the second embodiment is formed in a size and shape that can accommodate the pair of left and right latches 4 and the rotating cylinder 6B, and has a notch-like shape through which the front ends of the left and right latches 4 are inserted. The side holes 7a are formed. For this reason, under the second embodiment, a square part 23 is formed at the boundary between the left and right latches 4 and the guide part 19, and a square concave part 24 is formed on both sides of the bearing part 21. The insertion of 24 regulates the rotation of the left and right latches 4. Therefore, the through hole Ba on the box body B side is round.
[0025]
Therefore, when the pair of left and right latches 4 is incorporated in the rotary cylinder 6B integral with the operation handle 3 under the side lock device having such a configuration, a state in which one compression coil spring 5 is interposed is obtained. When the left and right latches 4 are inserted from the guide portion 19 side while being overlapped with each other inside the rotating cylinder 6B and the rotating cylinder 6B is rotated, a pair of pins 10 projecting into the rotating cylinder 6B correspond to each other. The left and right latches 4 are guided from the notch groove 16 into the cam groove 14 and supported by the rotary cylinder 6B so as to be able to appear and retract.
[0026]
When the box body B is in the closed state, as shown in FIG. 9, the biasing spring pressure of the compression coil spring 5 mounted inside the guide portion 19 of each latch 4 defined in a cylindrical shape is used. The front ends of the pair of left and right latches 4 pass through the notch-shaped side holes 7a of the housing 7 and the round through holes Ba formed in the both side walls of the box body B to the lock holes Pa of the instrument panel P. The box body B is locked at the closed position. In this case, as shown in FIG. 10, the operation handle 3 is not operated.
[0027]
Further, when the locked box body B is rotated in the opening direction, as shown in FIG. 11, when the operation handle 3 is swung, the rotary cylinder 6B rotates in conjunction with this operation. The pin 10 on the cylinder 6B side moves along the corresponding groove edge of the cam groove 14, and the left and right latches 4 resist the biasing spring pressure of the single compression coil spring 5 as shown in FIG. Will be forced to retreat.
[0028]
Then, due to the forcible retraction of the left and right latches 4, the front ends of the left and right latches 4 also retreat from the corresponding lock holes Pa of the instrument panel P. Thereafter, the box body B automatically rotates to the open position. When the operation of the operation handle 3 is released after the box body B is rotated in the opening direction, the pin 10 is moved into the cam groove 14 by the biasing spring pressure of the compression coil spring 5. The tip of each left and right latch 4 protrudes again in the lock hole Pa direction by the biasing spring pressure of the compression coil spring 5 while moving in the reverse direction. At the same time, the rotating cylinder 6B also rotates in the reverse direction. The operating handle 3 is returned to the non-operating state.
[0029]
Conversely, when returning the opened box body B to the closed state, the box body B is rotated as it is toward the empty side of the instrument panel P. At this time, the box body B protrudes in the direction of the lock hole Pa. The taper surfaces 4 a provided to the left and right latches 4 are in contact with the instrument panel P surface where the lock holes Pa are formed, so that the left and right latches 4 resist the biasing spring pressure of the compression coil spring 5. Then, it moves while retreating, and again engages with the corresponding lock hole Pa, so that the box body B is put in the closed lock state. In this case, as in the first embodiment, since only the left and right latches 4 are retracted into the rotary cylinder 6B regardless of the operation of the operation handle 3, the operation handle 3 itself Since it is not put in the operating state, the appearance is also improved.
[0030]
Therefore, even under the side lock device according to the second embodiment, it is necessary to change the amount of protrusion and withdrawal of the latch 4 on both the left and right sides by setting the shape of the instrument panel P as a support and the box body B as a storage body. In such a case, it is possible to meet the demand by changing the length of the cam groove 14 or the latch 4 without changing the device itself as in the prior art. In addition, since the length in the horizontal axis direction is changed, it is not necessary to change the size of the housing 7.
[0031]
Moreover, in particular, in the second embodiment, the cam groove 14 is formed on the latch 4 side, and only the latch 4 needs to be changed. Since only one compression coil spring 5 is required, space saving can be expected, and the pin 10 engages with the cam groove 14 of each of the left and right latches 4 inside the cylindrical rotating cylinder 6B. A stable engagement state of the groove 14 can be ensured.
[0032]
【The invention's effect】
As described above, according to the present invention, in the case where it is necessary to change the amount of protrusion and withdrawal of the latch on both the left and right sides by adopting the above configuration and setting the shape of the support body and the housing body, Even if the device itself is not significantly changed, it is possible to meet the demand by changing the length of the cam groove or the latch, which is extremely reasonable. Moreover, since the length is only changed in the horizontal axis direction, there is no need to change the size of the housing.
