Description

[0001] LOCK STRUCTURE [0002]

The present invention relates to a locking mechanism for holding a lid for opening and closing an opening in a closed position.

In a glove box installed in an instrument panel of an automobile, a lock mechanism for holding the lid in the closed position is provided (for example, Patent Document 1). The lock mechanism according to Patent Document 1 is provided between an instrument panel (support) provided with an opening and a lead rotatably supported by the instrument panel. The lock mechanism has a lock hole formed in the instrument panel and a latch provided on the lead. The latch protrudes from the lead by the biasing force of the compression coil spring and is engaged with the lock hole. In addition, the latch is moved by the rotating cam member in response to the rotational motion of the operating handle provided on the lid against the biasing force of the compression coil spring, and can be released from the lock hole. As described above, the lock mechanism holds the lid in the closed position by engaging the lock hole with the latch moving back and forth by the operation of the operation handle.

However, the lock mechanism related to Patent Document 1 has a problem that the lead rattles against the instrument panel due to the gap between the latch and the lock hole. In addition, there is a problem that rattling in the thrust direction and the radial direction due to the rotation axis of the lead also occurs.

In order to solve the problems described above, there has been proposed a technique in which a flange portion is interposed between a lead and an instrument panel to eliminate the rattling between the lead and the instrument panel (for example, Patent Document 2). The tongue-and-groove apparatus according to Patent Document 2 has a base provided on the side surface of the lead, an abutment body rotatably connected to the base, and a torsion coil spring provided between the base and the abutment body, The resilient abutment body is slidingly joined to the instrument panel, thereby preventing rattling between the lead and the instrument panel.

As shown in Fig. 9, locking holes (locking portions) 17 provided concavely upwardly are formed on both left and right ends of the upper wall 15A. The lock hole 17 may be either a through hole or a closed hole. As shown in Figs. 1 and 9, ribs 18 for connecting the lateral walls 15B and the regulating walls 15C are provided at the boundary between the lateral walls 15B and the regulating walls 15C. The ribs 18 are formed in a substantially right-angled triangle when viewed from the top and bottom, and have a thickness in the vertical direction. The rib 18 is formed in a portion corresponding to the oblique side of the right triangle and is inclined toward the center side (the center in the lateral direction) of the opening 2 and toward the outside (rear side) (18A). The straight line orthogonal to the inclined plane 18A has a predetermined angle larger than 0 DEG and smaller than 90 DEG with respect to the axial direction (front-rear direction) of the opening 2 in plan view (in plan view).

Fig. 2 is a front view of the lock mechanism, and Fig. 3 is a plan view of the lock mechanism. 2 and 3, the lock mechanism 5 includes a pair of left and right operating portions 21 which are engaged with the lock holes 17 of the instrument panel 3, And a pair of left and right link members 23 for transmitting the operation input of the operating portion 22 to the left and right operating portions 21, respectively. In the following description, the upper, lower, front and rear of each member are defined based on the state in which the lid 4 is in the closed position. The operating portion 21, the operating portion 22 and the link member 23 are provided on the back surface member 12 in the inner space of the lid 4. The operating portion 21 is provided at a central portion in an upper portion and in a lateral direction of a front surface side (front surface side) of the rear surface member 12. [ A pair of left and right operating portions 21 are provided at the left end and the right end in the upper side of the front side surface of the back side member 12 and in the left and right direction.

Since the pair of left and right operating portions 21 are symmetrical in the left and right, the operation portion 21 on the right side will be described below as an example. Fig. 5 is a perspective view of the operating portion of the lock mechanism as seen from the rear, Fig. 6 is a perspective view of the operating portion of the lock mechanism as seen from the front, and Fig. 7 is a perspective view of the operating portion as viewed from the rear through the operating portion housing. 5 to 7, the operating portion 21 includes an operating portion housing 26, a slider (force transmitting means) 27, a lock pin 28 (locking member), a slider- And an elastic member 29, as shown in Fig. The operation housing 26 has a plurality of fastening seats 31 and is fastened to the table side of the backing member 12 by bolts, screws, or the like.

The operating portion housing 26 is formed with a pin hole 32 for receiving the lock pin 28 and a slider hole 33 for receiving the slider 27. The pin hole 32 extends in the up-and-down direction, and the upper end thereof opens to the upper end of the operating part housing 26. The front end of the slider hole 33 opens to the front end of the operating housing 26 and the rear end of the slider hole 33 opens to the rear end of the operating housing 26 . The slider hole 33 is inclined to the left and right with respect to the front-rear direction so that the front end of the slider hole 33 is located on the right side of the rear end. The lower end of the pin hole (32) communicates with the intermediate portion in the front-rear direction of the slider hole (33). The front end of the operating housing 26 faces the top wall 12B of the backing member 12 and the front end of the operating housing 26 faces the plate portion 12A of the backing member 12, 12 on the right side of the side wall 12C. The upper side wall 12B of the back side member 12 has a first through hole 35 at a portion corresponding to the upper end of the pin hole 32. [ The plate-like portion 12A of the back side member 12 has a second through hole 36 at a portion corresponding to the front end of the slider hole 33. [ The second through hole 36 of the plate-like portion 12A of the back side member 12 extends to the right and the right end extends into the right side wall 12C.

The slider 27 is slidably supported by the slider hole 33 and is movable in the front-right direction and the rear-left direction. The slider 27 has a stopper (not shown), and the stopper is in contact with the actuating portion housing 26, so that the movement in the full-width direction is restricted to a predetermined position. That is, the front end position of the slider 27 with respect to the operating housing 26 is determined by the stopper. The front end portion 38 of the slider 27 passes through the front end opening of the slider hole 33 and the second through hole 36 of the back surface member 12 and moves forward Respectively. The front end 38 of the slider 27 is chamfered to form a smooth curved surface.

On the right and left side portions of the slider 27, guide ribs 41 extending in the front and rear direction are provided. In the hole wall of the slider hole 33, a guide groove 42 for receiving the guide rib 41 is formed. The attitude of the slider 27 with respect to the slider hole 33 is stabilized by the engagement of the guide rib 41 and the guide groove 42. [

A spring receiving portion 43 communicating with the slider hole 33 is formed in the lower portion of the operating portion housing 26. The spring receiving portion 43 is a concave portion extending upward and downward, and the upper end communicates with the slider hole 33. The spring receiving portion 43 accommodates a slider member 29 which is a torsion coil spring. One end of the slider member 29 is engaged with the wall of the spring receiving portion 43 and the other end of the slider member 29 is extended into the slider hole 33 and engaged with the slider 27. The slider 27 is biased to the right and to the left by the slider earthed member 29 and is located at the front end position in the initial state.

7, a slider-side cam portion (first cam portion) 44 is formed on the rear portion of the slider 27. As shown in Fig. The slider-side cam portion 44 has an inclined plate 46 which is inclined so that the slider-side cam portion 44 advances upward as it progresses toward the vehicle. A slit 47 is formed in the swash plate 46 so as to extend vertically (front por- tion) of the slider 27 through the upper and lower portions. The rear end of the slit (47) reaches the rear end of the slider (27) and has an opening end.

8 is an exploded perspective view of the lock pin. As shown in Fig. 8, the lock pin 28 has a cylindrical tip member 51 whose one end is open and closed at the other end, a rod-shaped base member 52 housed movably in the tip member 51, And a pin elastic member (first elastic member) 53 which is a compression coil spring provided between the distal end member 51 and the proximal end member 52 in the distal end member 51. The pin flange member 53 is resiliently biased in the direction in which the base end member 52 protrudes from the distal end member 51. The proximal end member 52 has a stopper (not shown), and the protruding position with respect to the distal end member 51 is determined by the stopper engaging with the distal end member 51. In other words, the lock pin 28 is elastically stretchable and is most protruded by the pin elastic member 53. At the protruding end of the base end member 52, a retaining piece 54 is provided. The engaging piece 54 is formed in a hook shape whose distal end portion is curved in a bending shape.

5 to 7, the lock pin 28 is received in the lock hole 17 such that the tip end member 51 is on the upper side and the base end member 52 is on the lower side. The protruding end (lower end) of the base end member 52 abuts the swash plate 46 of the slider side cam portion 44 of the slider 27 in a state where the lock pin 28 is received in the lock hole 17. [ The engaging piece 54 formed on the protruding end of the base end member 52 passes through the slit 47 of the slider 27 and is engaged with the edge of the slit 47 from the bottom side. Thus, the lock pin 28 is caught by the slider 27, and withdrawal from the lock hole 17 is suppressed. The engaging of the protruding end of the base end member 52 with the swash plate 46 and the engagement of the engaging piece 54 with the edge portion of the slit 47 (swash plate 46) The lock pin 28 moves up and down. When the slider 27 is positioned at the front end position, the base end member 52 of the lock pin 28 is located at the lowest position at the lowest position. From this state, when the slider 27 moves backward, the protruding end of the base end member 52 is pressed against the swash plate 46, and the second member moves upward. That is, when the slider 27 moves backward, the lock pin 28 moves upward due to the engagement of the slider side cam portion 44 and the base end member 52. [ When the engaging piece 54 of the base end member 52 is engaged with the edge of the front end of the slit 47, the base end member 52 is located at the uppermost position at the uppermost position.

As shown in Fig. 6, the operation housing 26 has an exposure hole 56 penetrating from the front portion thereof to the lower portion of the pin hole 32. As shown in Fig. The lower portion of the front side surface of the front end member 51 of the lock pin 28 is exposed to the outside of the operation part housing 26 by the exposure hole 56. [ 10 is a cross-sectional view showing the positional relationship between the operating portion of the lock mechanism and the opening edge of the instrument panel. As shown in Fig. 10, a columnar engaging convex portion 57 protruding forward is provided in a lower portion of the front surface of the distal end member 51. As shown in Fig. The engaging convex portion 57 is vertically movable with respect to the engaging convex portion 57 and the engaging convex portion 57 is movable upward and downward within the exposure hole 56. [

4 is a perspective view showing the operating portion of the lock mechanism (omitting the housing of the operating portion). 1 to 4, the operating portion 22 includes an operating portion housing 61 joined to the rear surface of the back member 12, a lever (handle) 62 rotatably supported on the operating portion housing 61, Lt; / RTI > The lever 62 has a rotary shaft extending in the left-right direction on its upper portion, and a lower end thereof is a free end. A lever elastic member 65 which is a torsion coil spring is opened between the lever 62 and the operating unit housing 61. The lever 62 is elastically biased to the initial position where the free end approaches the back member 12 . The surface member 11 has a lever hole 63 which is a through hole at a portion corresponding to the lever 62. [ The lever 62 is exposed to the rear of the lid 4 through the lever hole 63 and the operator can grasp the lever 62 through the lever hole 63. [ The lever 62 is formed with a pair of right and left pressing pieces 64, which are convex portions projecting in a columnar shape.

The left and right pair of link members 23 are members extending in the left-right direction and are formed symmetrically with respect to each other. The left end portion of the right link member 23 is supported on the operating portion housing 61 so as to be displaceable in a predetermined range along the left and right direction. Likewise, the right end portion of the left link member 23 is supported on the operating section housing 61 so as to be displaceable in a predetermined range along the left-right direction. The link member 23 on the right side has a stopper (not shown), and the movement of the link member 23 in the forward direction is limited to a predetermined position by abutting the stopper against the operating unit housing 61. Similarly, the left link member 23 has a stopper (not shown), and the stopper is abutted against the operating unit housing 61 so that the leftward movement is limited to a predetermined position. A link elastic member 66, which is a torsion coil spring, is opened between the left and right link members 23, and the left and right link members 23 are disposed in a direction away from each other. Accordingly, in the normal state, the right link member 23 is located at the rightmost position within the displaceable range, and the left link member 23 is located at the leftmost position within the displaceable range.

As shown in Fig. 4, a first link side cam portion 68, which is an inclined plane, is formed on the left end portion of the right link member 23 and the right end portion of the left link member 23, respectively. Each of the first link side cam portions 68 is capable of abutting against the pressing piece 64 of the lever 62. When the lever 62 is rotated from its initial position against the resilient force of the torsion coil spring by the operation of the operator, the right and left pressing pieces 64 are engaged with the first link side cam portion 68 of the left and right link members 23, Respectively. Each of the first link side cam portions 68 converts a load applied by the pressing piece 64 into a load in a direction in which the link members 23 are brought close to each other. The link members 23 move toward the center in the direction in which they approach each other against the laminating force of the linking elastic members 66 in response to the rotational movement of the lever 62. [ In other words, the link member 23 on the right side moves to the left side and the link member 23 on the left side moves to the right side corresponding to the rotational movement of the lever 62 from the initial position. When the lever 62 is rotated to the initial position side, the pressing piece 64 retracts, and the right link member 23 moves to the right due to the linting force of the link rib member 66, 23 move to the left.

As shown in Fig. 6 and later-described Fig. 12, a second link side cam portion (second cam portion) 71, which is a cam groove of a closed tube provided forwardly concave, is formed on the rear surface of the right end portion of the right link member 23. The second link side cam portion (71) opens to the lower end of the link member (23). And a cam surface 72 whose surface faces leftward and downward is formed on the right side of the second link side cam portion 71. [ When the lock pin 28 is in the lower end position, the engaging convex portion 57 is located at the lower portion of the second link side cam portion 71. [ As the lock pin 28 moves from the lower end position to the upper end position, the engaging convex portion 57 moves into the second link side cam portion 71. The engaging convex portion 57 is located in the vicinity of the upper end of the cam surface 72 in the second link side cam portion 71 when the lock pin 28 is in the upper position. The cam surface 72 presses the engaging convex portion 57 downward and the distal end member 51 is compressed so that when the lock pin 28 is in the upper position, And is displaced toward the base end member (52) against the lashing force of the coil spring. Since the base end member 52 is engaged with the slider 27 and the position is restricted by the slider, the distal end member 51 is displaced toward the base end member 52, . The lock pin 28 is extended by the biasing force of the pin flange member 53 because the cam surface 72 is separated from the engaging convex portion 57 when the link member 23 on the right side moves again again, Return to length.

In this way, when the lock pin 28 is in the upper position, the lock pin 28 is contracted by the operation of the lever 62. On the other hand, when the lock pin 28 is at the lower end position, since the engaging convex portion 57 is separated from the engaging surface of the second link side cam portion 71, even if the lever 62 is operated, , And maintains the normal length.

The left link member 23 is symmetrical with the second link side cam portion 71 of the right link member 23 and is provided with a second link side cam portion 71 that performs the same function.

Next, the operation of the lock mechanism 5 when the lid 4 is opened and closed will be described with reference to Figs. 11 to 18. Fig. Figs. 11 to 16 are sectional views showing the operating portion 21 of the lock mechanism 5 in each state when the lid 4 is closed. Fig. 17 and 18 are cross-sectional views showing the operating portion 21 of the lock mechanism 5 when the glove box is opened.

11, when the lid 4 does not reach the closing position and the slider 27 is separated from the rib 18, that is, the lid 4 is opened (first state) And the slider 27, which is resiliently mounted on the member 29, is located at the front end position. Thus, the lock pin 28 engaged with the slider side cam portion 44 of the slider 27 is positioned at the lower end position. The lock pin 28 is in an extended state due to the resilient force of the compression coil spring and the upper end surface of the lock pin 28 is disposed at a position substantially coinciding with the surface of the upper side wall 12B of the back side member 12. [ 12, the engaging convex portion 57 of the lock pin 28 is disposed at a position away from the second link side cam portion 71 of the link member 23 and is separated from the cam surface 72 have. The engaging convex portion 57 does not come into contact with the cam surface 72 even if the lever 62 is operated and the link member 23 is moved right and left.

When the front end portion 38 of the slider 27 comes into contact with the rib 18 from the first state shown in Figs. 11 and 12 in the closing direction of the lead 4, The second state shown in Fig. 13, in the second state, the front end of the slider 27 abuts on the inclined surface 18A of the rib 18, so that when the lid 4 moves in the closing direction (forward), the slider 27 Moves backward in the slider hole 33 against the lubrication force of the slider member 29. As shown in Fig. The lock pin 28 engaged with the slider side cam portion 44 of the slider 27 is moved upward at the lower end position and the tip end member 51 constituting the upper end thereof is moved more than the upper surface of the back side member 12 And protrudes upward. As the upward movement of the lock pin 28 (the base member 52) proceeds, the top surface of the first member abuts against the top wall 15A. At this time, since the lid 4 has not yet reached the closed position, the distal end member 51 does not face the front face of the locking hole 17 and can not enter the locking hole 17. When the upward movement of the base end member 52 proceeds, the pin flange member 53 contracts and the lock pin 28 contracts. The leading end member 51 resiliently attached to the pin flange member 53 in correspondence with the movement of the lead 4 to the closed position maintains contact with the top wall 15A while being held on the top wall 15A Slide. 14, in the second state, the engaging convex portion 57 provided on the distal end member 51 moves upward and enters the second link side cam portion 71. As shown in Fig.

When the movement from the second state shown in Figs. 13 and 14 to the closing direction of the lid 4 is further advanced, the third state shown in Figs. 15 and 16 is attained. 15, the leading end member 51 of the lock pin 28 and the lock hole 17 face each other in the front face, and when the lead 4 reaches the closed position, The tip end member 51 is extended and enters the lock hole 17. Thus, the lock pin 28 is caught in the lock hole 17, so that the lead 4 is held in the closed position. 16, when the leading end member 51 of the lock pin 28 protrudes into the lock hole 17, the engaging convex portion 57 provided on the distal end member 51 is engaged with the second link side cam portion 71, And is disposed in the vicinity of the upper end of the cam surface 72.

In the third state, since the slider 27 resiliently attached to the slider elastic member 29 comes into contact with the inclined surface 18A of the rib 18, the rattling of the lead 4 with respect to the instrument panel 3 is suppressed . The pair of left and right sloping faces 18A are directed toward the center side (the center side in the lateral direction) of the opening 2 and also toward the outside (rear side) of the opening 2, the slider 27 and the slider- The lead 4 is led to the center side of the opening 2 and also to the outside of the opening 2. As a result, the rattling in the radial direction of the support shaft 14 due to the shape (clearance) between the support shaft 14 of the lid 4 and the bearing hole of the instrument panel 3, (Gap) between the top end member 51 of the lock pin 28 and the lock hole 17 due to the shape (gap) in the left-right direction of the lock pin 2 in the thrust direction of the support shaft 14, In the rotation direction of the support shaft 14 is suppressed.

The lever 62 is operated to release the engagement by the lock mechanism 5 from the third state in which the lid 4 is held in the closed position by the lock mechanism 5. [ When the operator grips the lever end of the lever 62 and pulls backward, the lever 62 rotates and a pair of left and right pressing pieces 64 push the first link side cam portion 68 of the left and right link members 23 . Thus, the left and right link members 23 move in the left and right direction in the center, that is, in the directions close to each other, against the resilient force of the lever resilient piece 65. [ The engaging convex portion 57 of the lock pin 28 abuts on the cam surface 72 of the second link side cam portion 71 as shown in Fig. 18 when the right link member 23 moves to the left. Then, in response to the rightward movement of the second link side cam portion 71, the engaging convex portion 57 slides on the cam surface 72 and moves downward. The same applies to the link member 23 on the left and the operating portion 21. 17 and 18, the distal end member 51 is moved downward to be detached from the lock hole 17 to open the lid 4, as shown in Figs.

When the lid 4 is opened from the closed position, the slider 27 protrudes in the frontward direction due to the resilient force of the slider elastic member 29, and the lock pin (not shown) engaged with the slider 27 in the base member 52 28 move downward. As a result, the lock mechanism 5 returns to the first state shown in Figs. 11 and 12.

The slider 27 for driving the lock pin 28 is always engaged with the edge portion 15 of the opening 2 at the closed position of the lid 4 in the glove box 1 according to the present embodiment, The rattling force of the slider tentering member 29 acts between the lead 4 and the edge portion 15 so that the rattling of the lead 4 with respect to the instrument panel 3 is suppressed. The slider 27 is moved by abutting against the rib 18 and drives the lock pin 28 so that the lock pin 28 is driven corresponding to the position of the lead 4. The lock pin 28 does not protrude outwardly of the lead 4 when the lead 4 is in the open position so that the lock pin 28 does not protrude out of the opening 2 when the lead 4 is closed. I do not get caught in a dog club. Since the lock pin 28 is housed in the lead 4 when the lead 4 is open, the design of the lead 4 is improved.

In the glove box 1 according to this embodiment, since the slider 27 suppresses the rattling of the lid 4, the lead 4 and the lid 4 are provided as separate members between the lid 4 and the instrument panel 3, It is not necessary to provide a member for resiliently urging in a predetermined direction.

Although the description of the concrete embodiment has been described above, the present invention can be widely modified without being limited to the above embodiment. For example, the lid 4 may have a basket (box member) bonded to the front side of the back side member 12. The basket may be entirely accommodated in the opening 2 when the lid 4 is in the closed position and partially released outside the opening 2 when the lid 4 is in the open position. Further, the basket may be joined to the inside of the opening 2.

The operation unit 21 and the link member 23 are provided on the left and right sides of the single operation unit 22 in the above embodiment, the number of the operation unit 21 and the link member 23 is one , Or three or more.

In the above embodiment, the lock device of the present invention is applied to the glove box 1. However, the lock device of the present invention is not limited to the case where the opening is closed by a rotatable lead such as a furniture or a storage box of a system kitchen It can be applied to various storage devices.
