Description

  The present invention is provided in a door panel that opens and closes an opening of a storage box, and a lock bar extending in the left-right direction with respect to the front view of the door panel is engaged with an engagement hole formed in a side wall of the storage box to close the door panel. The present invention relates to a bowl-shaped side lock device that is held in a state and that opens a door panel when a lock bar is removed from an engagement hole.

  A side lock device is disposed in a grab box for a vehicle. This side lock device locks the door that opens and closes the opening of the grab box to the grab box and restricts the door from opening during vibration or sudden acceleration / deceleration.

  A general side lock device is composed of a pair of left and right lock pins that can slide in opposite directions and is attached to a door (see, for example, Patent Documents 1 and 2). The pair of lock pins is biased in a direction protruding toward the side wall of the box body. The tip of each lock pin engages with an engagement hole formed in the left and right side walls of the box body. For this reason, the door can maintain the state locked to the box main body.

  When a push button switch or the like is pressed, the pair of lock pins slide in a direction away from the box body, and the engagement between the end of each lock pin and the box body is released. For this reason, the lock is released, the door is movable with respect to the box body, and the box body can be opened.

  When the pair of lock pins are operated independently, there is a case where only one of the lock pins is engaged with the engagement hole due to the door being displaced with respect to the box body. In this case, since the door is locked to the box body with the position shifted, a large force is applied to the side lock device or the door, and the side lock device or the door may be deformed. Therefore, in recent years, a side lock device in which a pair of left and right lock pins operates in synchronization is common.

  For example, in the glove box described in Patent Document 1, a pair of left and right lock pins operate in synchronization by forming a rack on each of the pair of lock pins and disposing a pinion gear therebetween. Moreover, in the lid opening / closing apparatus described in Patent Document 2, the pair of left and right lock pins operate in synchronization by connecting the base ends of the pair of lock pins with a rotation lever.

JP 2006-327332 A JP 2011-012543

  However, in a structure that is synchronized by the rack and pinion gear, tooth jump due to external force may occur, or the protruding amounts of the left and right lock pins may differ due to assembly errors, and the door may open due to vibration or impact. Further, when a large load is applied, the door may not open even if the push button switch is pressed due to interference between the lock pin and the engagement hole.

  Parts such as a pair of lock pins, pinion gears, and rotating levers are disposed between the outer and inner of the grab door. Therefore, if the shape of the part is increased in order to operate stably, the inner shape of the grab door bulges toward the inside of the grab box, and the storage capacity of the grab box is reduced. Moreover, rigidity is required for the inner and / or outer, which is against the request for weight reduction.

  This invention is made | formed in view of such a situation, and avoids the above malfunction by reducing the number of parts arrange | positioned between outer and inners, such as a grab door, and making it a simple structure. This is a problem to be solved.

A feature of the side lock device of the present invention that solves the above problems is a side lock device that is provided in a door panel that opens and closes an opening of a storage box, and the storage box has engagement holes on both side walls sandwiching the opening. A movable pin engageable with the engagement hole is movably held outside the storage box, and a rod is held on the door panel so as to be linearly movable relative to the door panel. An operation unit that has a lock part that engages with the joint hole, the tip of the movable pin abuts on the other end of the rod opposite to the lock part, and moves the rod to the outside of the storage box or the door panel by manual operation Formed,
The door panel is held in a closed state by the lock portion of the rod engaging with one engagement hole and the movable pin passing through the other engagement hole and engaging with the door panel, and the rod is moved by operation of the operation portion. Thus, the engagement between the lock portion and the engagement hole is released, and the engagement between the movable pin and the door panel is released.

  According to the side lock device of the present invention, the lock portion of the rod engages with one engagement hole, and the movable pin passes through the other engagement hole and engages with the door panel, whereby the door panel is held in a closed state. ing. When the operation portion is manually operated, the rod moves to release the engagement between the lock portion and the engagement hole and the engagement between the movable pin and the door panel. Thereby, the door panel can open the opening, and the storage box can be used.

  That is, only the lock part at one end of the rod engages and disengages from the engagement hole, and the movable pin penetrates the other engagement hole and engages and disengages from the door panel. No mechanism, rotating lever, etc. are required. Moreover, since only one rod is sufficient and the rigidity of the rod itself can be increased, a holding member such as a rib for supporting the rod becomes unnecessary. Therefore, the number of parts arranged between the outer and inner can be reduced and the structure can be made simple, so that the door panel can be operated stably due to vibrations and shocks without causing problems such as tooth skipping. Problems such as opening can be avoided.

  Further, since the space between the outer and inner can be reduced, the storage volume can be increased, and the appearance quality when the door panel is opened is also improved.

  Furthermore, since the urging force of the operating portion and the urging force of the rod can be offset, the speed at which the rod moves when closing the door panel can be reduced. Therefore, the impact sound at the time of closing can be reduced.

FIG. 6 is a cross-sectional view of a main part in a door open state in a grab box and a grab door provided with a side lock device according to a third embodiment of the present invention.

  The side lock device of the present invention is provided in a storage box and a door panel that opens and closes the opening of the storage box. Examples of the storage box include a grab box, an accessory case, a console box, and the like, and conventional ones can be used as they are. Also, the door panel may be the same as that of the prior art made of, for example, an inner and an outer.

  The storage box has an engagement hole on each side wall across the opening. A rod is held on the door panel so as to be linearly movable relative to the door panel. The rod has a lock portion that engages with one engagement hole at one end, and engages with the one engagement hole from the door panel side.

  Further, a movable pin that can penetrate through the engagement hole is movably held outside the storage box, and engages with the door panel through the engagement hole from the outside of the storage box. The tip of the movable pin is in contact with the other end of the rod opposite to the lock portion. The rod and the movable pin do not need to be in a straight line, and the force for moving the rod may be transmitted to the movable pin, or the force for moving the movable pin may be transmitted to the rod. Then, the lock portion and the tip of the movable pin may be configured to engage with the engagement holes, respectively, and the center axes of the pair of engagement holes may not be coaxial with each other.

  An operation part for moving the rod directly or indirectly by manual operation is formed on the outside of the storage box or on the door panel. The operation unit can be a push button switch, a swing knob, or the like.

  When closing the door panel from the open state, it is desirable that the lock portion and the movable pin automatically engage with the engagement hole and the door panel. Therefore, it is desirable that the rod is provided with rod urging means and the movable pin is provided with movable pin urging means. As the biasing means, a coil spring, a leaf spring, rubber, or the like can be used.

  The door panel is held in the closed state by the lock portion of the rod engaging with one of the engagement holes, and the movable pin passing through the other engagement hole and engaging with the door panel. The door panel is opened by moving and releasing the engagement between the lock portion and the engagement hole and releasing the engagement between the movable pin and the door panel. The structure of the side lock device differs depending on the direction in which the rod moves by the operation of the operation unit or on which of the both ends of the rod the lock unit is formed.

  The operation unit can be a push button switch, a swing knob, or the like. For example, in the case of a push button switch, the base part, a button part held so as to be movable relative to the base part, a pressing member provided so as to be able to enter and exit the base part, and by directly pressing the button part or A movable pin moving mechanism that indirectly moves the movable pin in a direction to be immersed in the base, and the pressing member enters and exits from the base by pressing the button part. Here, either a structure in which the pressing member is immersed in the base by pressing the button part or a structure in which the pressing member exits from the base can be employed.

  For example, in the case where the pressing member is inserted into the base by pressing the button portion, the pressing member is used as a movable pin. When the door panel is in the closed state, the pressing member (movable pin) is engaged with the door panel so that the inner side of the door panel is engaged. The structure is advanced between the outer and outer. Then, the rod is biased so that the end of the rod opposite to the lock portion presses the tip of the pressing member (movable pin).

  When the button portion is pressed, the pressing member (movable pin) is moved in the direction of immersing into the base by the movable pin moving mechanism, and the rod is moved following the biasing force of the rod biasing means. As a result, the engagement between the pressing member (movable pin) and the door panel is released, and the engagement between the lock portion and the engagement hole is released synchronously, so that the storage box can be used by opening the door panel. As a means for opening the door panel, manual operation, spring force, dead weight of the door panel, or the like can be used.

  The movable pin can also be provided on the side opposite to the operation unit. In this case, the movable pin passes through one engagement hole and engages and disengages from the door panel, and the lock portion of the rod engages and disengages from the other engagement hole on the side opposite to the movable pin. When the pressing member presses the lock portion by operating the operation portion, the lock portion is released from the other engagement hole, and the end opposite to the lock portion of the rod presses the movable pin, and the movable pin is released from the door panel. Become. At this time, when the operation unit is a push button switch, the movable pin moving mechanism is configured to move in a direction in which the pressing member protrudes from the base by pressing the button unit.

  If the operation part and the movable pin are formed on both ends of the rod in this way, the operation part can be operated even when a large load acts on the door panel from the stored items and the operation of the movable pin becomes difficult. By moving the rod, the movable pin can be disengaged and the door panel can be opened reliably.

  As the movable pin moving mechanism, when the operation unit is a swing knob or the like, a known link mechanism that moves the movable pin by operating the operation unit can be used. In the case where the operation unit is a push button switch or the like, the direction in which the button unit is pressed and the moving direction of the pressing member generally intersect, and a known taper groove engagement or taper surface engagement is used. be able to.

  Hereinafter, embodiments of the present invention will be specifically described by way of examples.

  As shown in FIG. 1, an instrument panel 100 is disposed in a passenger compartment of an automobile, and a grab box 101 is formed on the instrument panel 100. The grab box 101 is pivotally hinged at the lower end of the grab door 200, and the upper end of the grab door 200 swings to open and close the opening of the grab box 101. The instrument panel 100 is provided with a push button switch 2 adjacent to the grab box 101. The grab box 101 and the grab door 200 incorporate the side lock device of this embodiment, and the lock is released by pressing the push button switch 2, and the grab door 200 swings downward by its own weight to open the opening of the grab box 101. .

  As shown in FIG. 2, the grab door 200 includes an outer 201 having a soft design surface and an inner 202 integrated by welding, and an outer 201 that is exposed to the passenger compartment and an inner 202 that reinforces the back surface thereof. Constitutes the door panel. In the space between the outer 201 and the inner 202 at the upper part (oscillating end side) of the door panel, the rod 1 of the side lock device of the present embodiment is disposed so as to be movable in the left-right direction.

  FIG. 3 shows a cross-sectional view of the main part in a state where the grab door 200 closes the grab box 101 (when locked). On the left and right side walls of the grab box 101, a box right engagement hole 102 and a box left engagement hole 103 are formed. A right door engagement hole 203 and a left door engagement hole 204 are formed in the left and right side walls of the grab door 200, respectively.

  In the space between the outer 201 and the inner 202, a rod 1 having a substantially U-shaped cross section is disposed so as to be movable in the left-right direction. The rod 1 extends in the left-right direction, and a lock portion 10 that can be engaged with the box left engagement hole 103 is formed at the left end portion. One end of the spring 11 is held at the intermediate portion of the rod 1, and the other end of the spring 11 is held by a flange 205 (see FIG. 2) protruding from the inner 202.

  The push button switch 2 includes a concave base portion 20 formed integrally with the instrument panel 100, a button portion 21 held relative to the base portion 20 in the vehicle front-rear direction, and a left-right direction with respect to the base portion 20. The movable pin 22 is provided so as to be relatively movable in the (vehicle width direction), and the spring 23 biases the button portion 21. The button portion 21 is formed with an inclined groove 24 extending diagonally from the front to the left and the protrusion 25 protruding from the movable pin 22 is engaged with the inclined groove 24 to constitute a movable pin moving mechanism. A tapered surface 26 is formed at the tip of the movable pin 22.

  At the time of locking shown in FIG. 3, the spring 23 urges the button portion 21 to exit the base portion 20, the movable pin 22 passes through the box right engagement hole 102 and engages with the door right engagement hole 203, The front end of the rod 1 is in contact with the end surface of the rod 1 opposite to the lock portion 10 through the door right engagement hole 203. That is, the rod 1 is pressed by the movable pin 22 and moved leftward, and the lock portion 10 passes through the door left engagement hole 204 and engages with the box left engagement hole 103. Since the pressing force of the movable pin 22 due to the urging of the spring 23 is larger than the spring force of the spring 11, the spring 11 is compressed, and the urging force for moving the rod 1 to the right is stored in the spring 11.

  Therefore, at the time of locking shown in FIG. 3, the lock portion 10 passes through the door left engagement hole 204 and engages with the box left engagement hole 103, and the movable pin 22 passes through the box right engagement hole 102 and engages with the door right engagement. By engaging with the joint hole 203, the left and right sides of the grab door 200 are held by the instrument panel 100, and the opening of the grab box 101 is closed.

  When the grab box 101 is used, the button portion 21 of the push button switch 2 is pressed against the urging force of the spring 23. Then, the protrusion 25 moves in the inclined groove 24 and the movable pin 22 is pulled into the base portion 20. Then, as shown in FIG. 4, the rod 1 moves to the right following the movable pin 22 by the bias of the spring 11. As a result, the movable pin 22 and the door right engagement hole 203 are disengaged, and at the same time, the lock portion 10 and the box left engagement hole 103 are disengaged. Therefore, the grab door 200 swings by its own weight and opens the grab box 101.

  Then, when the pressing of the button part 21 is released, the button part 21 moves in the direction of exiting the base part 20 by the bias of the spring 23 as shown in FIG. Accordingly, the protrusion 25 moves in the inclined groove 24, and the movable pin 22 penetrates the box right engagement hole 102 and protrudes into the grab box 101. The rod 1 is restricted from projecting from the right door engagement hole 203 by a stopper device (not shown) formed between the inner 202 and the spring 11 stores a slight urging force in this state. Therefore, movement of the rod 1 within the grab door 200 is restricted, and abnormal noise is prevented from being generated during vibration.

  When the grab door 200 is closed after the grab box 101 is used, if the rocking end of the grab door 200 is swung so as to be lifted, the right side portion of the grab door 200 comes into contact with the tapered surface 26 of the movable pin 22. When the rocking is further continued thereafter, the movable pin 22 moves so as to be pulled into the base 20 against the biasing force of the spring 23 by the action of the tapered surface 26. When the end surface of the rod 1 opposite to the lock portion 10 is positioned opposite the box right engagement hole 102, the movable pin 22 is moved to the left side by the bias of the spring 23, and the box right engagement hole 102 is moved. It penetrates and engages with the door right engagement hole 203. Along with this, the rod 1 is pressed by the movable pin 22 and moves to the left, and the lock portion 10 passes through the door left engagement hole 204 and then engages with the box left engagement hole 103. The locked state shown in FIG.

  At this time, since the urging force by the spring 23 and the urging force by the spring 11 cancel each other, the acceleration of the rod 1 at the time of locking becomes small. Accordingly, it is possible to reduce abnormal noise generated by impact.

  Therefore, according to the side lock device of the present embodiment, a rack and pinion mechanism, a rotation lever and the like are not required. Further, since one rod 1 is sufficient for the conventional rack and pinion mechanism using a pair of lock pins, the rigidity of the rod 1 itself is increased, and a holding member such as a rib for supporting the rod 1 is not necessary. Therefore, the number of parts arranged between the outer 201 and the inner 202 can be reduced and the structure can be made simple, so that the operation is stable without problems such as tooth skipping, and the grab door is opened by vibration or impact. Can be avoided.

  Further, since the space between the outer 201 and the inner 202 can be reduced, the storage volume can be increased, and the appearance quality when the grab door 200 is opened is also improved.

  In the present embodiment, as in the first embodiment, the side lock device of the present invention is adopted for the grab door of the automobile. Parts having the same structure as in the first embodiment will be described with the same reference numerals as in the first embodiment.

  FIG. 6 shows a cross-sectional view of the main part in a state where the grab door 200 closes the grab box 101 (when locked). In the space between the outer 201 and the inner 202, a rod 3 having a substantially U-shaped cross section is disposed so as to be movable in the left-right direction. The rod 3 extends long in the left-right direction, and a lock portion 30 that can be engaged with the box right engagement hole 102 is formed at the right end portion.

  The push button switch 2 includes a concave base portion 20 formed integrally with the instrument panel 100, a button portion 21 held relative to the base portion 20 in the vehicle front-rear direction, and a left-right direction with respect to the base portion 20. The pressing member 27 is provided so as to be relatively movable in the (vehicle width direction), and the spring 23 biases the button portion 21. The button portion 21 is formed with an inclined groove 28 extending obliquely from the front to the right and the protrusion 25 protruding from the pressing member 27 is engaged with the inclined groove 28 to constitute a movable pin moving mechanism.

  Inside the instrument panel 100, a movable pin 4 is disposed in the vicinity of the left side wall of the grab box 101. The movable pin 4 is arranged coaxially with the central axis of the box left engagement hole 103 and can enter and exit from the box left engagement hole 103. One end of the movable pin 4 is pivotally supported by a flange 104 projecting from the instrument panel 100, and is urged by a spring 40 in a direction projecting from the box left engagement hole 103 into the grab box 101. A tapered surface 41 is formed at the tip of the movable pin 4.

  At the time of locking shown in FIG. 6, the spring 23 urges the button portion 21 in the direction of exiting the base portion 20, the pressing member 27 is pulled into the base portion 20, and the tip is removed from the box right engagement hole 102. On the other hand, the movable pin 4 biased by the spring 40 passes through the box left engagement hole 103 and engages with the door left engagement hole 204, and further passes through the door left engagement hole 204 and the tip of the rod 3. It is in contact with the end surface opposite to the lock portion 30. That is, the rod 3 is pressed by the movable pin 4 and moved rightward, and the lock portion 30 penetrates the door right engagement hole 203 and engages with the box right engagement hole 102.

  Therefore, at the time of locking shown in FIG. 6, the lock portion 30 engages with the box right engagement hole 102, and the movable pin 4 passes through the box left engagement hole 103 and engages with the door left engagement hole 204. The left and right sides of the grab door 200 are held by the instrument panel 100 and the opening of the grab box 101 is closed.

  When the grab box 101 is used, the button portion 21 of the push button switch 2 is pressed against the urging force of the spring 23 and the urging force of the spring 40. Then, the protrusion 25 moves in the inclined groove 28, and the pressing member 27 enters the box right engagement hole 102 as shown in FIG. Along with this, the rod 3 is pressed by the pressing member 27 and moves to the left, and the lock portion 30 comes out of the box right engagement hole 102. On the other hand, the end of the rod 3 opposite to the lock portion 30 presses the movable pin 4 by the pressing force from the pressing member 27. Thereby, the engagement between the movable pin 4 and the door left engagement hole 204 is released. Therefore, the grab door 200 swings by its own weight and opens the grab box 101.

  Then, when the pressing of the button portion 21 is released, the button portion 21 moves in the direction of exiting the base portion 20 by the bias of the spring 23 as shown in FIG. Along with this, the protrusion 25 moves in the inclined groove 28, and the pressing member 27 is drawn into the base 20. On the other hand, the movable pin 4 penetrates the box left engagement hole 103 by the bias of the spring 40 and protrudes into the grab box 101.

  When the grab door 200 is closed after the grab box 101 is used, the left side portion of the grab door 200 comes into contact with the tapered surface 41 of the movable pin 4 if the swing end of the grab door 200 is lifted up. Thereafter, when the rocker is further swung, the movable pin 4 is moved into the instrument panel 100 against the biasing force of the spring 40 by the action of the taper surface 41. When the end surface of the lock portion 30 of the rod 3 is positioned to face the box right engagement hole 102, the movable pin 4 moves to the right side by the bias of the spring 40, passes through the box left engagement hole 103, and engages the door left engagement. Engages with the joint hole 204. Along with this, the movable pin 4 presses the rod 3, and the rod 3 moves to the right. Then, the lock part 30 penetrates the door right engagement hole 203 and engages with the box right engagement hole 102, and the grab door 200 is in the locked state shown in FIG.

  Therefore, according to the side lock device of the present embodiment, the rack and pinion mechanism, the rotation lever, and the like are not required as in the first embodiment. Further, since one rod 3 is sufficient for the conventional rack and pinion mechanism using a pair of lock pins, the rigidity of the rod 3 itself is increased, and a holding member such as a rib for supporting the rod 3 is not required. Therefore, the number of parts arranged between the outer 201 and the inner 202 can be reduced and the structure can be made simple, so that the operation is stable without problems such as tooth skipping, and the grab door is opened by vibration or impact. Can be avoided.

  Further, since the space between the outer 201 and the inner 202 can be reduced, the storage volume can be increased, and the appearance quality when the grab door 200 is opened is also improved.

  Further, in the first embodiment, when the load due to the contents of the grab box 101 is large, a large load acts on the movable pin 22 in the closed state of the grab door 200. Therefore, it is assumed that the grab door 200 cannot be opened because it is difficult to move the movable pin 22 even when the button portion 21 is pressed due to the interference between the movable pin 22 and the door right engagement hole 203. However, according to the side lock device of this embodiment, even when the interference between the movable pin 4 and the door left engagement hole 204 occurs, the button portion 21 can be pressed to move the rod 3 to the left. The grab door 200 can be opened.

  In the present embodiment, a spring that directly biases the rod 3 is not used, but a biasing member similar to the spring 11 of the first embodiment may be provided between the inner 202 and the rod 3. For example, as shown in FIG. 9, a spring 31 that urges the rod 3 toward the left is disposed. The spring force of the spring 31 is set smaller than the spring force of the spring 40. A stopper device (not shown) is formed between the rod 3 and the inner 202 so that the end of the rod 3 opposite to the lock portion 30 does not protrude from the door left engagement hole 204 when the grab door 200 is open. regulate. In this state, the spring 31 is in a state where a slight urging force is stored. By doing so, the movement of the rod 3 in the grab door 200 is restricted even in the open state, and it is possible to prevent abnormal noise from being generated during vibration. Further, since the urging force by the spring 31 and the urging force by the spring 40 cancel each other, the acceleration of the rod 3 at the time of locking becomes small. Therefore, when the grab door 200 is closed, it is possible to reduce noise generated by an impact.

  In the present embodiment, as in the first embodiment, the side lock device of the present invention is adopted for the grab door of the automobile. Parts similar in structure to the first embodiment will be described with the same reference numerals as in the first embodiment.

  As shown in FIG. 10, an instrument panel 100 is disposed in the passenger compartment of the automobile, and a grab box 101 is formed on the instrument panel 100. The grab box 101 is pivotally hinged at the lower end of the grab door 200, and the upper end of the grab door 200 swings to open and close the opening of the grab box 101. A knob 5 is swingably provided on the upper driver seat side of the grab door 200. The grab box 101 and the grab door 200 incorporate the side lock device of the present embodiment, and the lock is released by swinging the knob 5 so as to pull the knob 5 toward the front side, and the grab door 200 swings downward by its own weight. Open 101 openings.

  As in the first embodiment, the grab door 200 is formed by integrating an outer 201 having a soft design surface and an inner 202 by welding. In the space between the outer 201 and the inner 202 at the upper part (swinging end side) of the grab door 200, the rod 1 of the side lock device of the present embodiment is disposed so as to be movable in the left-right direction.

  As shown in FIGS. 11 to 13, the knob 5 is pivotally supported at one end 50 in a recess 206 formed in the outer 201 and is accommodated in the recess 206 so that the other end 51 can swing. The rotating shaft 52 is provided with a spring (not shown), and the other end 51 of the knob 5 is biased by the spring in a direction in which the knob 5 is accommodated in the recess 206. A knob pin 53 is integrally formed on the knob 5.

  FIG. 14 shows a cross-sectional view of the main part in a state where the grab door 200 closes the grab box 101 (when locked). On the left and right side walls of the grab box 101, a box right engagement hole 102 and a box left engagement hole 103 are formed. A right door engagement hole 203 and a left door engagement hole 204 are formed in the left and right side walls of the grab door 200, respectively.

  In the space between the outer 201 and the inner 202, a rod 1 having a circular cross section is disposed so as to be movable in the left-right direction. The rod 1 extends in the left-right direction, and a lock portion 10 that can be engaged with the box left engagement hole 103 is formed at the left end portion. A cam block 12 having a triangular cam hole 13 is integrally formed on the right end side (driver's seat side) of the rod 1, and as shown in detail in FIG. 11, the cam pin 13 has a knob pin 53 of the knob 5. Are engaged. As shown in an enlarged view in FIG. 15, the cam hole 13 includes a parallel surface 130 that extends parallel to the longitudinal direction of the rod 1, an inclined surface 131 that extends from the parallel surface 130 toward the outer 201, and an inclined surface 131. And a right-angled surface 132 extending perpendicularly to the longitudinal direction of the rod 1 from the tip of the rod toward the parallel surface 130.

  A spring 14 is disposed between the inner 202 and the rod 1 to urge the rod 1 toward the right. One end of the spring 14 is held at an intermediate portion of the rod 1, and the other end of the spring 14 is held by a flange 205 (see FIG. 2) protruding from the inner 202. The spring force of the spring 14 is set smaller than the spring force of the spring 40. A stopper (not shown) is formed between the rod 1 and the inner 202 so that the end of the rod 1 opposite to the lock portion 10 does not protrude from the door right engagement hole 203 when the grab door 200 is open. doing. In this state, the spring 14 is in a state where a slight urging force is stored.

  Inside the instrument panel 100, a movable pin 4 is disposed in the vicinity of the right side wall of the grab box 101. The movable pin 4 is arranged coaxially with the central axis of the box right engagement hole 102 and can enter and exit from the box right engagement hole 102. One end of the movable pin 4 is pivotally supported by a flange 104 projecting from the instrument panel 100 and is urged by a spring 40 in a direction projecting from the box right engagement hole 102 into the grab box 101. A tapered surface 41 is formed at the tip of the movable pin 4.

  At the time of locking shown in FIG. 14, the movable pin 4 is advanced by the spring 40 and passes through the box right engagement hole 102 and engages with the door right engagement hole 203. Further, the rod 1 is pressed by the movable pin 4 and moves to the left, and the lock portion 10 passes through the door left engagement hole 204 and engages with the box left engagement hole 103. The knob pin 53 of the knob 5 is locked at a position (A) (see FIG. 15) where the parallel surface 130 and the inclined surface 131 of the cam hole 13 intersect, and restricts further movement of the rod 1 in the left direction. ing.

  When the grab box 101 is used, the other end 51 of the knob 5 is pulled toward the passenger compartment side against the biasing force of the spring 40 and the spring (not shown) in the knob 5. Then, as shown in FIG. 16, the rod 1 moves to the right due to the engagement between the knob pin 53 and the inclined surface 131 and the urging of the spring 14, and accordingly the movable pin 4 also moves to the right. When the lock portion 10 of the cam hole rod 1 is removed from the box left engagement hole 103 and the tip of the movable pin 4 is removed from the door right engagement hole 203, the grab door 200 swings by its own weight and opens the grab box 101. The knob pin 53 of the knob 5 is locked at a position (B) where the inclined surface 131 and the right-angled surface 132 intersect, and restricts further movement of the rod 1 in the right direction.

  As shown in FIG. 17, when the grab door 200 swings and the engagement between the grab door 200 and the movable pin 4 is released, the movable pin 4 passes through the box right engagement hole 102 by the bias of the spring 40. Projects into the grab box 101. When the finger is released from the knob 5, the knob 5 is accommodated in the recess 206 formed in the outer 201 by urging of a spring (not shown). At this time, the knob pin 53 moves along an arcuate locus centering on the rotation shaft 52 of the knob 5, and becomes a position (C) in contact with the parallel surface 130.

  Since the spring 14 and a stopper (not shown) are formed, the rod 1 is pressed against the stopper by the urging force of the spring 14 even in the open state, and the rod 1 is restricted from moving in the grab door 200. Therefore, it is possible to prevent the generation of noise due to a collision during vibration. Furthermore, even if the knob 5 is swung in the state shown in FIG. 17, the rod 1 does not move. At this time, the end portion of the rod 1 opposite to the lock portion 10 is regulated so as not to protrude from the door right engagement hole 203, so that the appearance is good.

  When the grab door 200 is closed, the inner 202 of the grab door 200 engages with the tapered surface 41 of the movable pin 4 and the movable pin 4 moves backward. When the movable pin 4 and the door right engagement hole 203 are in a coaxial position, the movable pin 4 is advanced by the bias of the spring 40 and engaged with the door right engagement hole 203. Accordingly, the rod 1 is pressed by the movable pin 4, the rod 1 moves to the left, and the lock portion 10 engages with the box left engagement hole 103. Further, as the rod 1 moves, the knob pin 53 is relatively moved and locked at a position (A) where the parallel surface 130 and the inclined surface 131 of the cam hole 13 intersect.

  When the movable pin 4 and the door right engagement hole 203 are in the coaxial position, the right end surface of the rod 1 is in a position substantially coincident with the outer peripheral edge of the door right engagement hole 203. Is smoothly moved from the surface of the inner 202 to the end face of the rod 1, and the tip of the movable pin 4 thereafter is always in contact with the right end face of the rod 1. Further, since the spring forces of the spring 14 and the spring 41 are offset from each other, an abnormal noise due to a collision at the time of locking hardly occurs.

  Therefore, according to the side lock device of the present embodiment, a rack and pinion mechanism, a rotation lever and the like are not required. Further, since one rod 1 is sufficient for the conventional rack and pinion mechanism using a pair of lock pins, the rigidity of the rod 1 itself is increased, and a holding member such as a rib for supporting the rod 1 is not necessary. Therefore, the number of parts arranged between the outer 201 and the inner 202 can be reduced and the structure can be made simple, so that the operation is stable without problems such as tooth skipping, and the grab door is opened by vibration or impact. Can be avoided.

  Further, since the space between the outer 201 and the inner 202 can be reduced, the storage volume can be increased, and the appearance quality when the grab door 200 is opened is also improved. Furthermore, the occurrence of abnormal noise during locking can be greatly suppressed.

  In the present embodiment, the side lock device of the present invention is applied to the grab door. However, the present invention is not limited to the grab door, and can be used for a door lock structure of doors of various storage boxes such as a console door and a door for a accessory box.
