Description

  The present invention relates to a side lock device for locking a movable member that is swingably attached to a fixed member to the fixed member in a closed position.

  In general, on the passenger seat side of an instrument panel (fixed member) of a vehicle, a glove box (movable member) of a lid type or a storage unit integrated type is arranged. The grab box is swingably attached to the instrument panel, and swings between an open position where the opening of the instrument panel is opened and a closed position where the opening is closed. Usually, the grab box contains small items and documents (for example, vehicle verification), etc., so that articles stored in the grab box will not scatter due to impact when the vehicle gets over the step, etc. A locking device is provided for locking the grab box to the instrument panel in the closed position.

  Examples of the locking device include a center locking device having a single locking portion at the center of the left and right of the grab box, and a side locking device having two locking portions on the left side and the right side of the grab box. The side lock device is excellent in design because a mechanism that locks both side portions of the grab box hardly causes a step on the design surface of the grab box and the instrument panel, and the lock portion is hardly noticeable from the passenger. In addition, since the lock portion does not get in the way when the article is stored in the grab box, it has excellent functionality.

  In general, the side lock device has a pair of left and right heel pins capable of moving back and forth between a forward position protruding from both sides of the grab box and a retracted position retracted into the grab box, and both the heel pins facing the forward position. An urging member for urging and an operating member for retreating the both-side pin at the forward position to the retracted position against the urging force of the urging member are provided. Then, the pair of left and right hook pins protruding from both sides of the grab box are hooked into the pair of left and right engagement holes on the instrument panel side, so that the grab box is locked in the closed position. The basic configuration is that the grab box is unlocked and the grab box is opened.

  For example, a side lock device disclosed in Patent Document 1 is shown in FIG. The side lock device 101 is a device that locks the grab box GZ (movable member) attached to the instrument panel PZ (fixed member) so as to be swingable to the instrument panel PZ in the closed position. The side lock device 101 includes a pair of left and right rod pins 102 and 103 (rods) that enter and exit a pair of left and right engagement holes PZ2 and PZ3 (lock receiving portions) provided in the instrument panel PZ, and both rod pins 102 and 103. The gear 104, the operation knob 105 (operation member), and the flange pin urging member 107 (urging member) that urges the flange pins 102 and 103 in the protruding direction are provided. When the user pulls the lower end portion of the operation knob 105 toward the user against the urging force of the heel pin urging member 107, a part of the operation knob 105 is in sliding contact with the left heel pin 102, and the heel pin 102 is moved to the right. In conjunction with the movement of the heel pin 102, the right heel pin 103 is moved to the left.

  The operation knob 105 of the side lock device 101 is preferably in the center of the left and right of the grab box GZ in terms of balance, but in reality, there are various demands on appearance and operability, and the operation knob 105 is on the driver's seat side. In many cases, 105 is set. In this case, when the grab box GZ is closed, the tendency to push closer to the driver's seat side of the grab box GZ with the operation knob 105 becomes stronger. When the grab box GZ is pushed closer to the driver's seat, the load balance on the left and right of the grab box GZ is poor, so that the heel pin 102 on the passenger seat side is engaged with the engagement hole PZ2 due to bending of the grab box GZ. A phenomenon (so-called half-hanging) that is difficult to be applied easily occurs. When half-hanging occurs, the grab box GZ is not locked properly, and the grab box GZ may be deformed by an uneven load acting on the grab box GZ, or the operation may be significantly deteriorated due to permanent deformation of the grab box GZ. is there.

  As a countermeasure against such half-hanging, Patent Document 2 discloses a side lock device that can more reliably prevent half-hanging caused by the engagement resistance of the lock portion. The side lock device disclosed in Patent Document 2 includes a trigger (lock piece driving means) at the left and right centers of the grab box. When the grab box is closed, this trigger is activated by colliding with the storage device body that is integrally attached to the instrument panel, and the engagement claw (lock piece) in the retracted position is engaged with the engagement hole (catch part). After confronting, the engaging claw is inserted into the engaging hole.

JP 2010-13035 A JP2011-255777A

  Although the side lock device disclosed in Patent Document 2 can more reliably prevent half-hanging due to the engagement resistance of the lock portion, a mechanism for fitting the trigger and the engagement claw into the engagement hole Is complicated. For this reason, compared with the side lock apparatus 101 currently disclosed by patent document 1, this side lock apparatus has a concern that the manufacturing cost rises because there are many parts.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a side lock device capable of preventing half-locking of a lock portion with a simple configuration that suppresses an increase in the number of parts. .

  Hereinafter, each means suitable for solving the above-described problems will be described with additional effects and the like as necessary.

  (1) In the side lock device of the present invention, a movable member having a design surface that can swing between an open position that opens the opening of the fixed member and a closed position that closes the opening is provided at the closed position. A side lock device that locks onto the side of the movable member, and a forward position that protrudes from each side of the movable member and engages with each engagement hole of the fixed member, and a retreat where the engagement with each engagement hole is released A pair of scissors pins having an engaging claw that can be moved back and forth between the positions at the tip, and moving synchronously in a direction parallel to the swing axis of the movable member and opposite to each other, and the engagement of at least one of the scissors pins A guide structure that guides the advancing and retreating direction of the engaging claw so that the joint claw can be retracted in an oblique direction with respect to the swing axis of the movable member and away from the design surface; and the retracted position while being guided by the guide structure On the tip side of the pin The engaging claw is held so as not to move forward by abutting in the direction parallel to the swing axis of the movable member, and for releasing the stopper provided on the fixed member when the movable member swings to the closed position. A stopper structure that releases the holding of the engaging claw by pushing the tip end side of the flange pin closer to the design surface, and the engaging claw that is guided by the guide structure is provided on the movable member. The biasing member that biases the swinging shaft in an oblique direction and away from the design surface, and biases the engaging claw toward the forward movement position, and both the flange pins in the forward movement position are attached to the front end. And an operating member that moves back to the retracted position against the biasing force of the biasing member.

  According to such a configuration, the stopper structure prevents the engaging claw from advancing by coming into contact with the distal end side of the flange pin that is guided to the guide structure and retracted to the retracted position from the direction parallel to the swing axis of the movable member. Hold. The urging member urges the engaging claw in a direction away from the design surface. Therefore, the engaging claw can be stably held at the retracted position unless a force is applied to push the tip end side of the heel pin in the direction approaching the design surface against the urging force of the urging member. Further, when the movable member swings to the closed position, the stopper releasing projection provided on the fixed member pushes the tip end side of the heel pin in a direction approaching the design surface against the urging force of the urging member. Thus, the holding of the engaging claw by the stopper structure is released. The urging member urges the engaging claw toward the forward movement position, so that the engagement claw whose holding is released advances to the forward movement position. Note that the above-described parallel direction of the swing axis includes not only a strict parallel direction but also a substantially parallel direction slightly inclined with respect to the swing axis.

  The urging member provided in the conventional side lock device has only the function of urging the heel pin toward the forward movement position by urging the heel pin in the direction parallel to the swing axis of the movable member. However, the urging member provided in the side lock device of the present invention is arranged to urge the engaging claw of the heel pin in an oblique direction with respect to the swing axis of the movable member and in a direction away from the design surface of the movable member. Yes. Thereby, one urging member has a urging force in a direction orthogonal to the oscillating shaft of the movable member for holding the engaging claw in the retracted position, and the oscillating shaft of the movable member for moving the engaging claw forward. And an urging force in a direction parallel to.

  Therefore, according to the side lock device of the present invention, the engagement claw can be stably held in the retracted position during the swinging of the movable member by a simple configuration that suppresses the increase in the number of parts compared to the conventional side lock device. It is possible to hold, and it is possible to reliably prevent half-hanging caused by the engagement resistance of the lock portion.

  (2) In the side lock device of the present invention described in (1), preferably, the guide structure includes a guide groove and a guide pin that is inserted into the guide groove and moves along the groove shape of the guide groove.

  According to such a configuration, the guide structure can be constructed with a simple configuration. Here, the guide groove and the guide pin can be provided at the position where the guide groove is provided on the member fixed to the movable member and the guide pin is provided on the side of the flange pin. Further, a guide pin can be provided on the side of the member fixed to the movable member and a guide groove can be provided on the side of the flange pin.

  (3) In the side lock device of the present invention described in the above (2), preferably, the groove shape of the guide groove is such that the retracting direction of the engaging claw at the forward movement position is the swing shaft of the movable member. A parallel portion extending in the direction parallel to the swing axis so as to be regulated in a parallel direction; and an inclined portion extending in a direction oblique to the swing axis of the movable member and away from the design surface following the parallel portion. Yes.

  According to such a configuration, when the engaging claw is in the forward movement position, the guide pin is inserted into the parallel portion of the guide groove, so that the retracting direction of the engaging claw is in the direction parallel to the swing axis of the movable member. It is regulated. That is, the engaging claw in the forward position is held so as not to move in a direction perpendicular to the swing axis of the movable member. Therefore, even when a force in a direction perpendicular to the swing axis is applied to the movable member locked to the fixed member, the engaging claw does not move backward, and an external force such as an impact acting on the movable member is applied. On the other hand, the locked state of the movable member can be reliably maintained.

  (4) In the side lock device of the present invention described in the above (1) to (3), preferably, the biasing member is held by a member whose one end is fixed to the movable member, and the other end is It is a metal torque spring, compression spring, or tension spring held by the flange pin guided by the guide structure.

  According to such a configuration, a metal torque spring, compression spring, or tension spring is used as the biasing member. For this reason, it is difficult for the urging force to be reduced by creep as in the case of using a synthetic resin or rubber urging member for a long time, and the engagement claw is moved toward the forward position by the metal urging member for a long time. It can be energized stably. Therefore, the performance of the side lock device can be maintained over a long period of time.

  (5) In the side lock device according to the present invention described in the above (1) to (4), preferably, the operation member is a push button disposed on the movable member.

  According to such a structure, the lock | rock of a movable member is cancelled | released by pushing the push button arrange | positioned at the movable member. At this time, since the direction in which the push button is pressed and the direction in which the movable member attempts to open are opposite, at least the engagement claw and the engagement hole face each other after the push button is pressed to retract the engagement claw. The engaging claw must be held in the retracted position until the movable member swings to the position where it disappears. Therefore, when the operation member disposed on the movable member is a push button, it is more important to hold the engaging claw in the retracted position than when the operation member is an operation knob. As described above, according to the side lock device of the present invention, it is possible to stably hold the engaging claw in the retracted position while the movable member is swinging. There is little fear. Therefore, the side lock device of the present invention can operate reliably even when the operation member is a push button.

  Moreover, according to the structure of this invention, the push button which is an operation member is arrange | positioned at the movable member. For this reason, compared with the conventional side lock device in which the push button is disposed on the fixed member, the push button does not remain on the fixed member when the movable member is opened. Can be improved.

When the grab box G is in the closed position, the stopper releasing rib P4 formed on the instrument panel P is inserted into the slit Gi2 (see FIGS. 5 and 7).

  Based on FIGS. 5 to 10, the operation of the side lock device 1 after the grab box G locked in the closed position is opened until it is locked again in the closed position will be described. As shown in FIG. 5, the user pushes the push button 5 against the urging force of the push button urging member 8 and the heel pin urging member 7 in a state where the grab box G is locked in the closed position. Then, the link member 4 rotates from the pressure receiving start position toward the pressure receiving end position. Then, as shown in FIG. 6, both flange pins 2, 3 are retracted in conjunction with the movement of the link member 4. At this time, the left flange pin 2 is guided in the backward direction by the first guide groove 6b1 and the second guide groove 6c1, and rotates clockwise in FIG. 6 while retracting rightward. Further, the right side pin 3 is guided in the backward direction by the first guide groove Go2 and the second guide groove 6d1, and rotates counterclockwise in FIG. 6 while retracting leftward.

  When the link member 4 is rotated to the pressure receiving end position by the push operation of the push button 5, the both side pins 2, 3 are retracted to the retracted position, and the both side pins 2, 3 are moved by the stopper structure of the present invention described above. Held in the retracted position. Since both the hook pins 2 and 3 move synchronously via the link member 4, the right hook pin 3 is also moved to the retracted position by holding the left hook pin 2 in the retracted position by the stopper structure of the present invention. Retained. After that, when the push operation of the push button 5 is stopped, the push button 5 returns to the pressing start position by the urging force of the push button urging member 8, but the both pin pins 2, 3 are held in the retracted position. To maintain. Then, as shown in FIG. 6, the grab box G swings from the closed position toward the open position by the weight of the grab box G and the repulsive force of the cushion member 10.

  Next, the operation of the left heel pin 2 will be described with reference to FIGS. FIG. 7 shows a state where the grab box G is locked in the closed position. FIG. 8 shows a state in which the grab box G is unlocked in the closed position. FIG. 9 shows a state in which the grab box G swings between the closed position and the open position. FIG. 10 shows a state where the grab box G is pushed to the closed position.

  When the user pushes the push button 5 from the state shown in FIG. 7, the first guide pin 2c is guided along the first guide groove 6b1 in the order of the parallel portion s, the inclined portion t, and the enlarged diameter portion u. Is done. When the push button 5 is pushed, as shown in FIG. 8, the grab box G is also pushed forward, so that the stopper release rib P4 has entered deeply between the distal ends of the two overhang portions 6b2. It becomes a state. In this state, the stopper release rib P4 becomes an obstacle, and the stopper projection 2g of the flange pin 2 cannot be brought into contact with both the overhanging portions 6b2. Then, when the push button 5 is pushed in to the maximum, as shown in FIG. 8, the first guide pin 2c moves to the right front corner of the enlarged diameter portion u of the first guide groove 6b1.

  When the push operation of the push button 5 is stopped from the state shown in FIG. 8, the heel pin 2 moves forward by the urging force of the heel pin urging member 7, and the left surface of the stopper projection 2g is the right surface of the stopper releasing rib P4. Once caught. When the user stops pressing the push button 5, the grab box G starts to swing from the closed position toward the open position as shown in FIG. Along with this, the stopper releasing rib P4 is pulled out from between the leading ends of the two stopper overhanging portions 6b2, so that the stopper projection 2g and the two stopper overhanging portions 6b2 can be brought into contact with each other. With such a stopper structure, the engaging claw 2a of the heel pin 2 is held so as not to move forward while the grab box G swings.

  When closing the grab box G, the grab box G is pushed to the closed position as shown in FIG. As a result, the stopper releasing rib P4 enters deeply between the tip portions of the stopper overhanging portions 6b2, and the stopper releasing rib P4 pushes the stopper protruding portion 2g backward while contacting the stopper protruding portion 2g. Then, the contact between the stopper projection 2g and the stopper overhangs 6b2 is released. FIG. 10 shows a state immediately after the contact between the stopper projection 2g and the stopper overhangs 6b2 is released. Immediately after the state shown in FIG. 10, the eaves pin 2 moves forward by the urging force of the eaves pin urging member 7, and the engagement claw 2a engages with the engagement hole P2 as shown in FIG.

  According to such a configuration of the present embodiment, the stopper structure formed by the contact between the stopper protruding portion 2g and the stopper protruding portions 6b2 is a guide structure formed by the first guide pin 2c and the first guide groove 6b1. The engaging claw 2a of the heel pin 2 retracted to the retracted position while being guided is held so as not to advance. Moreover, the heel pin urging member 7 urges the engaging claw 2a in a direction away from the design surface Ga. Accordingly, the engaging claw 2a is stably held in the retracted position unless a force is applied to push the distal end side of the heel pin 2 in a direction approaching the design surface Ga against the urging force of the heel pin urging member 7. be able to.

  Further, when the grab box G swings to the closed position, the stopper release rib P4 provided on the instrument panel P resists the urging force of the heel pin urging member 7 against the urging force of the heel pin urging member 7. By pushing in the direction approaching the surface Ga, the holding of the engaging claws 2a by the stopper structure is released. The hook pin urging member 7 urges the engaging claw 2a toward the advanced position, so that the engagement claw 2a released from being held moves forward to the advanced position.

  Thus, the single pin urging member 7 advances the urging force in the direction perpendicular to the swing axis of the grab box G for holding the engaging claw 2a in the retracted position and the engaging claw 2a. And an urging force in a direction parallel to the swing axis of the grab box G. Therefore, according to the side lock device 1 of the present embodiment, both the engaging claws 2a and 3a are provided during swinging of the grab box G with a simple configuration that suppresses an increase in the number of parts compared to the conventional side lock device. Can be stably held in the retracted position, and half-hanging caused by the engagement resistance of the lock portion can be reliably prevented.

The groove shape of the first guide groove 6b1 includes a parallel portion s extending in the direction parallel to the swing axis so as to restrict the backward direction of the engaging claw 2a at the forward position to the direction parallel to the swing axis of the grab box G. , An inclined portion t extending obliquely with respect to the swing axis of the grab box G and extending away from the design surface Ga is included after the parallel portion s.

  According to such a configuration, when the engagement claw 2a is in the forward movement position, the first guide pin 2c is inserted into the parallel portion s of the first guide groove 6b1, so that the retraction direction of the engagement claw 2a is changed. The grab box G is restricted in the direction parallel to the swing axis. That is, the engaging claw 2a at the forward movement position is held so as not to move in a direction orthogonal to the swing axis of the grab box G. Therefore, even when a force in a direction perpendicular to the swing axis is applied to the grab box G locked to the instrument panel P, the engaging claw 2a does not move backward and acts on the grab box G. The locked state of the grab box G can be reliably maintained against an external force such as an impact.

  Further, according to such a configuration, the engaging claw 2a is guided to the inclined portion t of the first guide groove 6b1, and the engaging claw 2a is inclined with respect to the swing axis of the grab box G and away from the design surface Ga. Retreat to. Thereby, even if it is a case where the engagement nail | claw 2a and the engagement hole P2 by the side of the instrument panel P have shifted | deviated to the front-back direction by a manufacturing error, an assembly error, etc., the engagement nail | claw 2a and the engagement hole P2 The engagement claw 2a can be easily retracted without generating a sliding resistance.

  In addition, according to the configuration of the present embodiment, since the heel pin urging member 7 is made of metal, a decrease in urging force due to creep occurs when a synthetic resin or rubber urging member is used for a long time. hard. Therefore, the engagement claw 2a can be stably urged over a long period of time toward the forward position by the metal heel pin urging member 7. Therefore, the performance of the side lock device 1 can be maintained for a long time.

  Moreover, according to the structure of this embodiment, the push button 5 is employ | adopted as an operation member. In the push button 5, the direction in which the push button 5 is pressed and the direction in which the grab box G tries to open are opposite to each other. High importance to do. As described above, according to the side lock device 1 of the present embodiment, the engaging claw 2a can be stably held in the retracted position while the grab box G is swinging, and with a simple configuration. Therefore, there is little risk of failure. Therefore, the side lock device 1 of this embodiment can operate reliably even when the operation member is the push button 5.

  Further, according to the configuration of the present embodiment, the push button 5 which is an operation member is arranged in the grab box G. For this reason, compared with the conventional side lock device in which the push button 5 is disposed on the instrument panel P side, the push button 5 does not remain on the instrument panel P when the grab box G is opened, so that the appearance is good. The design properties of the grab box G and the instrument panel P can be improved.
