Description

  The present invention relates to a two-drawer structure in which a drawer main body can be pulled out from both a front side and a back side of a storage case and can be pulled out in both directions.

  As for both drawers, for example, as described in Patent Document 1, after the housewife finishes cooking on the kitchen side and arranges on the hatch counter, the drawer moves to the dining side, opens the drawer from the dining side, and enters it. Take out the desired spoons, forks, etc. that are stored and serve them on the dining table. Then, clean the used tableware on the dining table on the hatch counter, move it to the kitchen side, and use it. It is convenient because it is possible to clean the dishes, open the drawer from the kitchen side, and quickly store the cleaned food utensils in the drawer.

  However, in the double drawer structure described in Patent Document 1, when the drawer is pulled out from one side, a concave space is formed on the other side. Garbage is easy to enter the space. Therefore, as described in Patent Document 2, the applicant of the present invention closes the opposite side of the drawer with the other front plate even when one front plate is connected to the storage box and pulled out outward. A double-drawer structure that can be used has been developed and has already been applied for a patent.

  In addition, as in the double-sided drawer (both drawer structure) described in Patent Document 3, a hook as an engagement device that is rotated and biased by a vine spring is provided at the bottom of the decorative plate (front plate). An engagement pin that can be engaged with the hook is projected from the drawer body (storage box), and the hook is engaged with the engagement pin, so that the decorative plate (front plate) and the drawer body (storage box) Some of them are connected to each other.

JP-A-5-277017 (second page, FIG. 1) JP 2004-188110 A (page 5, FIG. 3) JP 2004-81758 A (paragraphs 0017 to 0021, FIGS. 1 to 8)

  However, in the double drawer structure described in Patent Document 2, when the user pulls out the front plate quickly, the fitting portion (engaging portion) is not fitted into the fitting groove (engaged portion). In order to reduce this malfunction, play (for example, the front-rear width of the fitting groove) may occur in the coupling actuator or the fitting groove. The drawer body may be manufactured with a width larger than the front-rear width of the fitting portion), and this play allows the storage box to be moved relative to the front plate when the storage box is pulled out. In addition to the relative movement (rattle) of the body in the front-rear direction, there is a problem that, for example, the front plate collides with the storage box when storing the storage box.

  Moreover, in the double-sided drawer (both drawer structure) described in Patent Document 3, the hook is engaged with the engaging pin, so that the decorative plate (front plate) and the drawer body (storage box) Since the drawer main body (storage box) is moved away from the decorative plate (front plate), the relative movement in the direction away from the decorative plate (front plate) is restricted. When the urging force of the vine spring is weak, the user presses the decorative plate (front plate) to store the drawer body (storage box). When doing so, the hook may rotate against the urging force of the crane spring and disengage from the engagement pin, which may cause the drawer body and the decorative plate to move relative to each other. Or, if the urging force of the crane spring is increased, the decorative plate will be pulled during storage. And there was a fear that separated from the body.

  The present invention has been made paying attention to such problems, and during the drawer operation, the storage box moves relative to the front plate, or the storage box collides with the front plate. It is an object of the present invention to provide a double-drawer structure that can prevent the above.

  Movable units 46 and 47 as restricting members in the present embodiment are attached at positions close to the first engaging pieces 61 and 62 in the rotating levers 27 and 28 shown in FIG. Since the movable units 46 and 47 provided on the front side and rear side rotary levers 27 and 28 have the same configuration, the movable unit 46 of the rotary lever 27 provided on the front side will be described in detail as shown in FIG. Further, the movable unit 46 is rotatably supported by a pivot 48 provided on the rotation lever 27, and the pivot 48 is provided with a pivotal biasing force for the movable unit 46 in this embodiment. A winding spring 49 is provided as a spring member.

  Further, on the upper side of the movable units 46 and 47, second engagement pieces 63 and 64 are formed as restricting portions in the present embodiment. On the lower side of the movable units 46 and 47, locking portions 65 and 66 extending downward and having a substantially hook shape are formed (see FIG. 3). The locking portion 65 is disposed on the rear side (inward side) of the locking portion 67 of the rotating lever 27 so as to be overlapped in the front-rear direction, and is locked to a locking piece 69 provided on the fixed rail body 11. It is designed to be locked. Note that the locking portion 67 of the rotation lever 27 is indirectly locked to the locking piece 69 via the locking portion 65 of the movable unit 46, and the locking portion 67 of the rotation lever 27 and the movable unit 46. In a state where the locking portion 65 is locked to the locking piece 69, the second engagement piece 63 is immersed in the rotating lever 27 side (see FIG. 9).

  As shown in FIGS. 9 and 10, the state in which the second engagement piece 63 of the movable unit 46 is immersed in the rotating lever 27 side is that the restricting portion is retracted from the engaged portion in this embodiment. 11, the state in which the second engaging piece 63 of the movable unit 46 protrudes from the rotating lever 27 as shown in FIG. It is the contact position where a part contacts. The locking portion 65 of the movable unit 46 is provided so as to be movable between a contact position and a retracted position, as will be described later.

  As shown in FIG. 11, when the locking portion 65 of the movable unit 46 is separated from the locking piece 69, the movable unit 46 is rotated upward by the urging force of the winding spring 49, and the second engagement piece 63 is The rotating lever 27 protrudes outward (frontward) from the first engagement piece 61 and is switched to the contact position.

  Next, the usage example of the two drawers 7 will be described in detail. When the storage box 8 is in the storage position, as shown in FIGS. 3 and 9, the locking portions 65 and 66 of the movable units 46 and 47 are The second engaging pieces 63 and 64 are immersed without the movable units 46 and 47 being rotated, because they are engaged with the engaging pieces 69 and 70 together with the engaging portions 67 and 68 of the rotating levers 27 and 28. The retracted position is set.

  When the user grasps the handle 34 of the front plate 9 on the front side and pulls it in the front direction (front plate side), as shown in FIGS. 5 and 10, the support rail 19 that supports the front plate 9 moves. The rotating lever 27 moves to the front side (outward side), the force that the locking piece 69 of the fixed rail body 11 locks the locking portion 67 of the rotating lever 27 is weakened, and the rotating lever 27 is pivoted. The first engagement piece 61 is engaged with the engagement pin 79 from the inner side (one side). In this state, the locking part 65 of the movable unit 46 is in a retracted position locked by the locking piece 69, and the second engagement piece 63 is immersed. Therefore, the first engagement piece 61 can be engaged with the engagement pin 79 without being obstructed by the second engagement piece 63, and the front plate 9 and the storage box 8 are connected.

  The connection state between the front plate 9 and the storage box 8 is not only that the front plate 9 and the storage box 8 are directly connected but also the front plate 9 and the storage box 8 as in this embodiment. It also shows a state of being connected so as to move in conjunction with each other via the support rail 19.

  Further, since the second engagement piece 63 is immersed when the storage box 8 and the front plate 9 are connected, a space in which the engagement pin 79 can move to the outer side (the other side) of the engagement pin 79. (Looseness) occurs, and malfunction of the rotating lever 27 and the first engagement piece 61 is reduced.

  When the front plate 9 is further pulled out, as shown in FIGS. 6 and 11, the locking portion 67 of the rotating lever 27 and the locking portion 65 of the movable unit 46 are separated from the locking piece 69 of the fixed rail body 11, The movable unit 46 is rotated by the urging force of the winding spring 49 so that the second engagement piece 63 protrudes upward to switch to the contact position, and the second engagement piece 63 is moved from the outer side (the other side). The engagement pin 79 is engaged. At this time, the first engagement piece 61 and the second engagement piece 63 are arranged at opposing positions with the engagement pin 79 interposed therebetween.

  Thus, the second engagement piece 63 moves from the retracted position to the contact position in accordance with the engagement of the first engagement piece 61 with the engagement pin 79 and contacts the engagement pin 79, and the front plate 9 When the storage box 8 is pulled out, the engagement pin 79 provided on the storage box 8 has a first engagement. Since it is sandwiched between the piece 61 and the second engagement piece 63 from the front-rear direction, relative fine movement (rattle) in the front-rear direction with respect to the connected front plate 9 generated in the storage box 8 is restricted. And since the pulled-out front plate 9 and the storage box body 8 are in a connected state, the storage box body 8 is pulled out outward (front plate side) as the front plate 9 moves. ing.

  As shown in FIG. 11, the tip end portion of the first engagement piece 61 is slightly inclined so as to be inclined toward the engagement pin 79, so that the first engagement piece 61 is disengaged from the engagement pin 79. This can be prevented, and the first engagement piece 61 and the engagement pin 79 can maintain the engaged state during the pull-out operation. Further, since the second engagement piece 63 is urged in the protruding direction by the winding spring 49, the second engagement piece 63 can be reliably protruded, thereby reducing the malfunction of the movable unit 46. Is done.

  As shown in FIG. 7, when the front plate 9 and the storage box 8 on the front side are pulled out, the front plate 10 on the back side is separated from the storage box 8 and interlocked with the storage box 8. Therefore, the front plate 10 can block the back side of the kitchen table 1, and the appearance of the kitchen table 1 can be improved without making a dent on the back side of the kitchen table 1. . In addition, it is possible to prevent intrusion of garbage and the like.

  When the handle 35 of the front plate 10 on the back side is pulled in the back direction (front plate side), as shown in FIG. 8, the back side rotation lever 28 provided on the upper support rail 20 operates. Then, the front plate 10 on the back side and the storage box 8 are connected and can be pulled out in the back direction (front plate side). At this time, similarly to the movable unit 46, the movable unit 47 is rotated, and the engagement pin 80 provided in the storage box body 8 is interposed between the first engagement piece 62 and the second engagement piece 64. The relative movement (rattle) in the front-rear direction with respect to the connected back side front plate 10 generated in the storage box 8 is regulated.

  Next, the two drawers 7 when the storage box 8 is stored will be described. When the user pushes the handle 34 of the front plate 9 on the front side toward the storage direction in the state where the drawer 7 is pulled out. When the engaging pin 79 of the storage box 8 and the rotation lever 27 are connected, the storage box 8 is moved in the storage direction together with the front plate 9. At this time, the second engagement piece 63 presses the engagement pin 79 and the first engagement piece 61 and the second engagement piece 63 restrict the relative movement of the front plate 9 and the storage box body 8 in the front-rear direction. As a result, the storage box 8 does not rattle (does not move relative), and the storage box 8 is moved in a direction approaching the front plate 9, so that the storage box 8 is moved to the front plate. Colliding with 9 is also prevented.

  Then, in the vicinity of the separation position between the rotation lever 27 and the engagement pin 79, the contact portion 42 provided on the lower support rail 19 is brought into contact with the contact piece 40 formed on the air damper 36, and the air The moving speeds of the front plate 9, the support rail 19, and the storage box 8 are all reduced by the urging force of the damper 36. At this time, the engagement pin 79 maintains the state of being engaged (contacted) with the first engagement piece 61 due to the restriction by the second engagement piece 63, and the storage box body 8 is moved to the front plate 9 during deceleration. It is possible to prevent the storage box body 8 from moving relative to the front and rear direction (shaking) by moving in the storage direction at a speed faster than the above speed.

  As shown in FIG. 10, after the storage box 8 is decelerated, the locking portion 65 of the movable unit 46 is locked by the locking piece 69, the movable unit 46 rotates, and the second engagement piece 63 is moved downward. Immerse yourself. Then, a space (clearance) in which the engagement pin 79 can move is formed on the outer side (the other side) of the engagement pin 79. Thereafter, the locking portion 67 of the rotation lever 27 is locked to the locking piece 69 via the locking portion 65 of the movable unit 46, and the rotation lever 27 rotates to engage the first engagement piece 61.
