Description

  The present invention relates to a lid opening / closing device, and more particularly to a lid opening / closing device suitable for an accessory case of a type in which a lid is stored in a storage portion when fully opened.

For example, an accessory case provided in an automobile center console or the like is known that includes a laterally open lid having one end connected to an opening surface of an article storage unit using a hinge. Since this lid becomes a hindrance if it protrudes in the open state, it may be configured to be stored outside the side wall of the article storage unit. However, if the lid is configured to be fully stored, the appearance is good. On the other hand, the free end of the lid is immersed from the opening surface, which hinders the closing operation. In view of this, there has been proposed a reversing spring in which the urging force in both the opening direction and the closing direction is reversed at an intermediate point of displacement so that the lid can be automatically opened and closed by a push button operation (Patent Literature). 1).
JP 2002-362237 A

  However, this conventional structure relies on the resilient force of the reversing spring for the holding force at both the opening and closing positions of the lid. Therefore, it is important to emphasize the holding force so that the lid does not vibrate at both the fully open and fully closed positions. When the force is increased, the operating force required for the opening / closing operation increases, and when the operating force is reduced, the holding force becomes insufficient, making it difficult to achieve both the operating force and the holding force. In addition, since the stroke for displacing the reversing spring to a position beyond the neutral point depends on the operation amount of the push button, the stroke that causes the reversing spring to exceed the neutral point is necessary for the push button. It was also difficult to make it smaller.

  The present invention has been devised to eliminate such disadvantages of the prior art, and its main purpose is to ensure a sufficient holding force of the lid in both the fully open and fully closed positions, the operating force, An object of the present invention is to provide a lid opening / closing device configured to achieve a great reduction in the amount of operation in a high dimension.

In order to solve such a problem, the present invention provides a lock means (first lock mechanism 5) for holding the fully closed position of the lid (lids 3a and 3b) and an accumulating force for biasing the lid in the opening direction. A lid opening / closing device having a force storage means (torsion coil spring 6) and an operation portion (release button 4) for unlocking the lock means, and the lid is automatically opened when the operation portion is unlocked. , A second urging force accumulating means (compression coil spring 9) for accumulating an urging force for moving the lid from the fully open position to an intermediate position in the closing direction, and holding the second urging force accumulating means at the urging force accumulation position. Second locking means (second locking mechanism 11) that operates, and when the operation portion is operated in the fully opened position of the lid, the second locking means is unlocked and the lid moves to a position in the closing direction. The lid to the fully closed position. Biasing force to the two biasing force storage means by causing moved is assumed to be configured to be accumulated. Further, in addition to the above configuration, a first unlocking means (upper release slider 19, lateral release slider 23) that releases the urging force of the urging force accumulating means when the operation unit is operated in the fully closed position of the lid, A second unlocking means (lower release slider 34) that releases the urging force of the second urging force accumulating means when the operation portion is operated in the fully open position of the lid, the first unlocking means, and the second unlocking It is preferable to have unlocking operation switching means (41) for selecting connection or non-connection with the means .
In particular, the lid may be a double-open lid that is connected via an interlocking mechanism (sector gear 14, spur gear 15) and performs a synchronous operation (Claim 3), and further interlocked with the movement of the lid in the opening direction. have good assuming that a cover (flap 8) covering said lid Te.
The present invention is, fully closed position of the lid is held by locking means, the cover opening and closing apparatus that cover the unlocking operation of the lock means is opened, it is assumed that providing a cover for covering the lid in the fully open position , the cover was intended to interlock the opening movement of the lid.

According to the present invention, the driving force for opening the lid uses the biasing force accumulated in the spring means and the holding force for the fully closed position of the lid depends on the lock means separately. A sufficient holding force of the lid at the position can be easily ensured. Since it is sufficient to apply an operation force and an operation amount sufficient to unlock the locking means, the operation force and operation amount can be reduced. Further, when the lid stored in the fully opened position is automatically moved to the middle position in the closing direction when the closing operation is performed, the manual closing operation is facilitated. In addition, since the operation from the midway position in the closing direction to the fully closed position is manually performed by the user, there is no fear of causing troubles such as an object or a hand due to an erroneous operation. In addition, since the opening operation and the closing operation for moving to the middle position in the closing direction can be performed by the common operation unit, the operation unit is not complicated.
In particular, if it is a double-open lid that is linked via an interlocking mechanism and performs a synchronous operation, the opening can be widened to improve usability, and the lid in the fully open position should be covered with a cover. For example, the opening surface can be flattened when fully opened, and it does not get caught when an article is inserted, and there is no gap, so there is no fear that coins or the like cannot be dropped and taken out.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  1 and 2 are perspective views of an entire accessory case to which the present invention is applied. The accessory case 1 is used by being embedded in, for example, a center console of a passenger car, and includes a pair of left and right lids configured to open a box 2 constituting an article storage unit and a double opening that closes an upper opening surface of the box 2. 3a and 3b. In the following description, the directionality is toward the paper surface of FIGS. 1 and 2, and the front side is “front”.

  In this accessory case 1, when both lids 3a and 3b are rotated in a symmetrical manner in the left-right direction, when the release button 4 provided on the upper part of the front wall of the box 2 is pushed in the fully closed position (FIG. 1), the right lid First, the box shown in FIG. 3 is obtained by the elastic force of the torsion coil spring 6 (see FIG. 4) which is unlocked and incorporated in the left lid 3a. The lids 3a and 3b are automatically opened until the vertical position along the left and right side walls 2 is reached. When the lids 3a and 3b are opened up to this position, the lids 3a and 3b are lowered by their own weight together with the slide base 7 which supports the lids 3a and 3b so as to be pivotable. Finally, the lids 3a and 3b are lowered. The free ends of 3b are lowered to a retracted position lower than the opening surface of the box 2, and the lids 3a and 3b in the retracted position are located at a pair of left and right flaps 8 pivotally attached to the upper edge sides of the left and right side walls of the box 2. The free end is covered (see FIGS. 2 and 4).

  Here, the flaps 8 are each provided with a torsion coil spring (not shown) on the pivot shaft so that the free ends of the flaps 8 rotate outward, that is, the free play of both the lids 3a and 3b in the retracted position. When the lids 3a and 3b move in the closing direction, they are pushed by the free ends of the lids 3a and 3b so that the free ends are directed inward. It is designed to rotate.

  When the release button 4 is pressed in a state where both the lids 3a and 3b shown in FIGS. 2 and 4 are fully opened and lowered, the elastic force of the compression coil spring 9 compressed when both the lids 3a and 3b are fully closed. As a result, the second lock mechanism 11 that has held the lifter 10 that is elastically biased upward in the lowered position is unlocked, and the lifter 10 is raised. The lifting force of the lifter 10 is applied to the rack slider 12 in contact with the upper surface of the lifter 10, the lids 3a and 3b and the slide base 7 are lifted together with the rack slider 12, and the free ends of the lids 3a and 3b are boxed. It moves to the intermediate position (refer FIG. 5) which protrudes somewhat from 2 opening surfaces.

  In this state, when the free end of either one of the lids 3a and 3b is manually pivoted in the closing direction, the left and right sides of the torsion coil spring 6 urging the left lid 3a are resisted against the elastic force. When the right lid 3b reaches the fully closed position, the first lock mechanism 5 is activated and the fully closed positions of both the lids 3a and 3b are held. Yes. At the same time, the rack slider 12 descends in conjunction with the closing operation of the right lid 3b to push down the lifter 10, compresses the compression coil spring 9 that elastically urges the lifter 10 upward, and the lifter 10 reaches the lower limit. The second lock mechanism 11 is actuated to hold the lowered position of the lifter 10. That is, it returns to the fully closed position shown in FIG.

  Next, the urging mechanism for applying the driving force for the lid opening operation and the driving force for the raising operation to the intermediate position to both the lids 3a and 3b will be described in more detail. The urging mechanism having substantially the same configuration is provided on both the front and rear sides of the box body 2. Hereinafter, the urging mechanism provided on the front side will be described.

  A slide base 7 is provided on the outer surface of the front and rear walls of the box body 2 so as to be slidable up and down. On the outer surface of the slide base 7, there are pivoted free ends of L-shaped arms 13a and 13b extending symmetrically from the front and rear ends at the outer edge of the lids 3a and 3b in the fully closed position. Yes.

  The right arm 13b is provided with a sector gear 14b having an appropriate angle around the pivot point. The sector gear 14b meshes with the right spur gear 15b and the rack gear 16 formed on the rack slider 12 slidable in the vertical direction in series in the axial direction. The left arm 13a is also provided with a sector gear 14a having an appropriate angle centered on the pivot point, which meshes with the left spur gear 15a meshed with the right spur gear 15b. The pair of spur gears 15a and 15b and the sector gears 14a and 14b constitute a synchronization mechanism that synchronizes the opening and closing operations of the left and right lids 3a and 3b by applying an opening and closing driving force to one lid. One spur gear 15b (15a) is set so that the opening speed of both lids 3a and 3b by the elastic force of the torsion coil spring 6 wound around the pivot shaft of the left arm 13a is appropriate. A known damper device (not shown) is connected to provide an appropriate rotational resistance.

  As shown in detail in FIG. 6, a vertical guide cylinder 17 is provided in the center of only the front wall of the box body 2 in the vertical direction. The upper part of the vertical guide cylinder 17 is integrated with the release button 4. The upper release slider 19, which is elastically biased upward by the compression coil spring 18, is slid. The right side of the upper release slider 19 is engaged with a notch 20 formed on the outer periphery of the sector gear 14b provided integrally with the right front arm 13b to hold the fully closed positions of the lids 3a and 3b. The first lock mechanism 5 is provided.

  The first lock mechanism 5 includes a horizontal release slider 23 that slides on a horizontal guide cylinder 21 that extends in the horizontal direction on the top of the front wall of the box body 2 and is elastically biased leftward by a compression coil spring 22; The first latch bolt 24 is slidably engaged with the right end portion of the horizontal guide cylinder 21 so as to be movable up and down.

  The left end of the horizontal release slider 23 is linked and connected to the upper release slider 19 via an inclined cam 25 having an angle of 45 degrees, for example. A vertical vertical cam slit 26 is provided in the engagement portion of the horizontal guide cylinder 21 with the first latch bolt 24, and a left upward inclination is provided in the engagement portion of the horizontal release slider 23 with the first latch bolt 24. A cam slit 27 is provided. The first latch bolt 24 is provided with a pin 28 that engages with both cam slits 26 and 27.

  On the other hand, on the outer surface of the front and rear walls of the box body 2, as shown in FIG. 4, a guide comprising an arc portion 29 a extending over an angle range exceeding approximately 90 degrees and a vertical portion 29 b continuing to the lower end of the arc portion 29 a. The protrusion 29 is provided in the left-right symmetrical position. Pins 30 projecting from sector gears 14 a and 14 b that are integral with the arms 13 a and 13 b are engaged with the outer peripheral surfaces of the guide protrusions 29. As a result, during the opening operation of the lids 3a and 3b, the slide base 7 is maintained at the uppermost position while the pin 30 is engaged with the arc portion 29a of the guide protrusion 29 (FIGS. 1 and 3). When the pins 3 reach the vertical portion 29b of the guide protrusion 29 when the lids 3a and 3b are in the vertical posture, there is no longer any thing that holds the slide base 7 in the uppermost position, so both the lids 3a and 3b in the fully open position, that is, the vertical posture. With this, the slide base 7 descends to its lowest position under its own weight (FIGS. 2 and 4). At this time, as described above, the flaps 8 pressed against the inner surfaces of both the lids 3a and 3b are opened outward by the action of the torsion coil spring while the both lids 3a and 3b in the vertical posture are lowered. .

  The lifter 10 slides up and down movably up and down on the guide portion 31 provided on the outer surface of the front and rear walls of the portion provided below the bottom wall of the box body 2 and, as described above, the bottom surface of the guide portion 31. It is elastically biased upward by a compression coil spring 9 that is contracted between the two. As shown in FIG. 7, the second lock mechanism 11 for holding the lowered position of the lifter 10 is slidably movable up and down to the lower part of the vertical guide cylinder 17 and is contracted at the bottom of the vertical guide cylinder 17. The lower release slider 34 is elastically biased upward by the compression coil spring 33, and the second latch bolt 35 is engaged with the lower release slider 34.

  The second latch bolt 35 engaged with the upper end surface of the lifter 10 is slidably slidably moved forward and backward to the lower portion of the vertical guide cylinder 17 and is provided with a forwardly-decreasing inclined cam slit 36 and a pin 37 provided on the lower release slider 34. When the lower release slider 34 moves downward, the inclined cam slit 36 moves back together with the pin 37. Further, the second latch bolt 35 is biased forward by the lower release slider 34 being resiliently biased upward. Note that the member 40 coupled with the pin 39 to the upwardly inclined cam slit 38 provided below the second latch bolt 35 allows the release button 4 provided on the front wall of the box 2 to be pushed down on the rear wall. A release force transmitting member for transmitting to a provided latch bolt to unlock the rear lifter.

  A switching mechanism 41 is provided between the upper release slider 19 and the lower release slider 34 to select the interlocking / non-interlocking of both. This switching mechanism 41 is pivotally attached to an intermediate release slider 42 connected to the upper release slider 19 and a lower end of the intermediate release slider 42 so that the free end can swing back and forth. It is composed of a connector 43 that is urged and biased in the direction of swinging forward. When the connector 43 is pushed by a slide cam 44 composed of an inclined surface and a protruding surface provided on the inner surface of the slide base 7, the free end is inclined backward.

  As shown in FIG. 8, the connector 43 is provided with left and right side walls 46 pivotally attached to the intermediate release slider 42 and urged by a torsion coil spring 45 wound around the pivot shaft. An inward projection 47 is formed on each free end of the inner surface of each side wall 46. Both protrusions 47 protrude with their edges facing each other, and an appropriate interval is provided between the opposing end surfaces.

  On the other hand, at the upper end of the lower release slider 34, a T-shaped protrusion 48 is formed in which the lower surfaces of both protrusions 47 of the connector 43 abut on the top surface. The leg portion 49 of the T-shaped protrusion 48 is dimensioned to pass through the gap between the protrusions 47 of the connector 43.

  Next, the operation of opening the lids 3a and 3b by pressing the release button 4 from the fully closed position will be described in detail.

  When the lids 3a and 3b are in the fully closed position, that is, when the slide base 7 is in the uppermost position, the inclined cam 44 provided on the back surface of the slide base 7 is not in contact with the connector 43 (FIG. 7). reference). In this state, since the free end of the connector 43 swings forward, even if the release button 4 is pushed and the connector 43 is lowered together with the upper release slider 19 and the intermediate release slider 42, the free end of the free end The protrusion 47 does not contact the T-shaped protrusion 48 of the lower release slider 34, and the downward movement of the intermediate release slider 42 does not affect the lower release slider 34 (see FIG. 9). At this time, as shown in FIG. 12, both the lids 3a and 3b are configured so as to be continuous with the decorative panel applied to the upper surface of the center console CS.・ It is pushed by the inner surface of 3b and tilts inward.

  In this state, when the release button 4 is pressed, the downward movement of the upper release slider 19 integrated with the release button 4 is converted into the rightward movement of the horizontal release slider 23 by the action of the 45-degree inclined cam 25. The horizontal release slider 23 moves to the right. Then, due to the rightward movement of the inclined cam slit 27 provided in the horizontal release slider 23, the first latch bolt 24 engaged with the pin 28 with the pin 28 faces upward along the vertical cam slit 26 of the horizontal guide cylinder 21. Move to. As a result, the protruding end of the first latch bolt 24 comes off the notch 20 of the sector gear 14b of the right front arm 13b integrated with the right lid 3b in the fully closed position, and the elastic force of the torsion coil spring 6 acting on the arm 13a of the left lid 3a. Thus, the lids 3a and 3b are automatically opened. When the release button 4 is released in this state, the upper release slider 19 returns to the original position by the elastic force of the compression coil spring 18, and the first latch bolt 24 is driven by the compression coil spring 22 acting on the lateral release slider 23. The state in which the tip is pressed against the outer peripheral surface of the sector gear 14b in the right arm 13b is maintained by the elastic force to the left.

  As described above, the right front arm 13b is unlocked and the lids 3a and 3b are opened synchronously, and then the lids 3a and 3b are lowered together with the slide base 7 to reach the fully opened position. . In this fully open position, as shown in FIG. 13, both lids 3a and 3b are stored in the lid storage space H defined outside the box 2 in the center console CS, and the storage space H The upper surface is closed with a flap 8. As a result, the gap in the lid storage space H can be made invisible when the lid is fully opened, and the appearance can be improved. In addition, there is no gap when the article is inserted, and there is no gap. There is no worry that you can not take out.

  Even if the release button 4 is pressed down until the slide base 7 is lowered during the opening operation, the gap between the projections 47 of the connector 43 can pass through the leg portions 49 of the T-shaped projection 48, so that the slide cam 44 It is avoided that the protrusion 47 of the connector 43 interferes with the T-shaped protrusion 48 when pressed.

  Next, details of the operation of the lifter 10 that pushes up both the lids 3a and 3b to the half-closed position together with the slide base 7 when the release button 4 is pushed from the fully open position where the slide base 7 is lowered to the lowest position together with both the lids 3a and 3b. Explained.

  When the slide base 7 is in the fully open position, the slide cam 44 on the back surface of the slide base pushes the connector 43 and moves its free end backward (see FIG. 10). When the release button 4 is pressed in this state, that is, when the lids 3a and 3b are fully opened, the upper release slider 19 and the intermediate release slider 42 integrated therewith move downward, and the lower surface of the inward projection 47 of the connector 44. Comes into contact with the top surface of the T-shaped protrusion 48 of the lower release slider 34 and pushes down the lower release slider 34. Then, the second latch bolt 35 engaged with the inclined cam slit 36 of the lower release slider 34 via the pin 37 moves backward to unlock the lifter 10 (see FIG. 11). As a result, the lifter 10 is raised by the elastic force of the compression coil spring 9 and pushes up the rack slider 12 in contact with the upper surface of the lifter 10. When the release button 4 is released in this state, the upper release slider 19 returns to the original position by the elastic force of the compression coil spring 18 and the lower release slider 34 returns to the original position by the elastic force of the compression coil spring 33. . As a result, the second latch bolt 24 also returns to the advanced position. Here, the portion other than the upper end portion on the back surface of the lifter 10 is cut out so as not to interfere with the tip end of the second latch bolt 24, so that the return of the second latch bolt 24 to the advanced position is not hindered.

  On the other hand, since the pin 30 is engaged with the vertical portion 29 b of the guide protrusion 29, the arms 13 a and 13 b cannot rotate, and the sector gear 14 b of the right arm 13 b maintains the meshing relationship with the rack gear 16. Accordingly, when the rack slider 12 rises, both the lids 3a and 3b and the slide base 7 rise together. As a result, the inner edges of the lids 3a and 3b push back the flap 8 and protrude upward from the opening surface of the box body 2. The rack slider 12 is provided with a known damper device, and its rising speed is set appropriately.

  Thus, in the state which protruded from the opening surface of the box 2, since the pin 30 engages with the circular arc part 29a of the guide protrusion 29, both arms 13a and 13b can be rotated. In this state, the free end of either one of the lids 3a and 3b is manually pivoted inward, and when both lids 3a and 3b reach the fully closed position, the tip of the first latch bolt 24 is engaged with the notch 20. As a result, the fully closed positions of the lids 3a and 3b are maintained.

  At the same time, the sector slider 14b rotated by the movement of the right lid 3b in the closing direction moves the rack slider 12 downward to push down the lifter 10. When the lifter 10 reaches the bottom position, the tip of the second latch bolt 35 is reached. Engages with the upper surface of the lifter 10 to hold the lowermost bottom position of the lifter 10.

  The above-described closing operation of the lids 3a and 3b is performed by applying a force against the reaction force of both the torsion coil spring 6 that biases the left lid 3a and the compression coil spring 9 that biases the rack slider 12 upward. Although it must be added to 3b, according to the above-described configuration, the distance from the free end to the pivot end of the lids 3a and 3b and the radius of the sector gear 14b meshing with the rack gear 16 of the rack slider 12 are sufficiently increased. Therefore, the force transmission efficiency is high, and the closing operation can be performed with a small operating force.

  The lid opening / closing device according to the present invention is widely applicable not only to vehicles such as trains, ships, and aircraft, but also to furniture, office equipment, kitchens, washstands, etc. that require lids for the article storage section. it can.
