Description

  Aspects of the present invention generally relate to a sliding door opening and closing mechanism.

  A sliding door having an adjacent first door and a second door, and in which at least the first door is a sliding type, in a fully closed state in which the first door and the second door are closed to improve design. Some configurations are flat. For example, as in Patent Literature 1, when fully closed, the adjacent first and second doors are flat, and when the sliding first door is opened, the first and second doors are closed. There is known a sliding door opening / closing mechanism that overlaps front and rear.

  In such a sliding door opening / closing mechanism, when the first door is opened from the fully closed state, there is a possibility that opposing side end surfaces of the first door and the second door may interfere with each other. For this reason, it is necessary to provide a gap between the first door and the second door in the fully closed state in consideration of the movable area when the doors are shifted from the fully closed state to the state where the doors overlap each other.

  However, such a gap may reduce the design of the sliding door. For example, in the first door and the second door, it is conceivable to form the shape of the side end surface facing each other when fully closed, but in this case, when the first door or the second door is opened. There is a concern that the design will deteriorate.

  For this reason, when fully closed, the adjacent first and second doors are in a flat state, and when the first door is opened, the first and second doors are overlapped with each other back and forth. Therefore, even if the gap provided between the first door and the second door at the time of fully closing is reduced, interference between the first door and the second door at the time of opening can be suppressed, and the design at the time of opening decreases. It is desired to be able to suppress the same.

JP 2007-32177 A

  The present invention has been made based on the recognition of such a problem, and even if the gap provided between the first door and the second door is made small when fully closed, the first door and the second door when opened. It is an object of the present invention to provide a sliding door opening / closing mechanism that can suppress interference with the sliding door and can also suppress a reduction in design at the time of opening.

  The first invention has a first door and a second door which are adjacent to each other, and is used for a slide door in which at least the first door is a slide type, and the first door and the second door are closed. The first door and the second door adjacent to each other are flat when closed, and when the first door is opened, the first door and the second door are overlapped with each other back and forth. An opening and closing mechanism, wherein the first door is slidably supported between a first closed position and a first open position, and the first door overlaps the second door in the first open position. A first support portion to be combined, a second support portion that movably supports the second door between a second closed position and a second open position, and the first door from the first closed position of the first door. A link for moving the second door so as to avoid interference with the first door in conjunction with the movement to the open position. A closing mechanism of the sliding door, characterized in that it comprises a mechanism.

  According to this sliding door opening / closing mechanism, there is an interlocking mechanism that interlocks with the movement of the first door from the first closed position to the first open position and moves the second door so as to avoid interference with the first door. Therefore, even when the gap provided between the first door and the second door at the time of full closing is made small, interference between the first door and the second door at the time of opening can be suppressed. Further, in the first door and the second door, there is no need to form the shape of the side end surface facing each other when fully closed in an inclined shape. For example, each side end surface of the first door and the second door can be a surface substantially orthogonal to the front surface. Therefore, it is also possible to suppress a decrease in design when the device is opened.

  In a second aspect based on the first aspect, the interlocking mechanism moves the first door in the front-rear direction when moving the first door from the first closed position to the first open position. An opening and closing mechanism for a sliding door, wherein the second door is moved in a direction opposite to the movement of the first door in the front-rear direction.

  According to the sliding door opening / closing mechanism, the behavior when the second door is moved so as to avoid interference with the first door can be reduced. For example, when the first door is moved, it is possible to prevent the second door from largely moving and giving the user a sense of discomfort. Therefore, it is possible to reduce the gap provided between the first door and the second door when the door is fully closed, and it is possible to further improve the design. Furthermore, even when the width (the depth of the door) of each side end surface of the first door and the second door is set large, interference between the doors can be avoided with a slight behavior.

  In a third aspect based on the first or second aspect, the first support portion closes the first door only at an operation in a direction in which the first door approaches the second door. And moving the first door from the first open position to the first closed position only by operating in a direction to separate the first door from the second door. The opening / closing mechanism of the sliding door.

  According to this sliding door opening / closing mechanism, for example, an operation such as sliding the first door after pulling it forward is not required, thereby simplifying the opening / closing operation of the first door and improving the usability of the sliding door. it can.

  In a fourth aspect based on any one of the first to third aspects, the first door faces the second door at the second closed position in the state at the first closed position. A first side end surface, wherein the second door has a second side end surface facing the first side end surface of the first door at the first closed position when in the second closed position. The interlocking mechanism moves the first side end face back and forth from the second side end face in response to movement of the first door from the first closed position to the first open position. Opening and closing the sliding door by inclining the door and moving the second door to incline the second door so as to separate the second side end face from the first side end face. Mechanism.

  According to this sliding door opening / closing mechanism, the behavior of the second door can be further reduced by inclining the first door and the second door, and between the first door and the second door when fully closed. Can be kept smaller. For example, even when the first door can be opened and closed only by an operation in a direction of approaching or moving away from the second door, interference between the doors can be suppressed only by inclining the first door and the second door, and a simple operation can be achieved. It can be realized with a configuration.

  In a fifth aspect based on any one of the first to fourth aspects, the interlocking mechanism is configured to simultaneously move the second door from the first closed position to the first open position. This is a sliding door opening and closing mechanism that moves the door.

  According to this sliding door opening / closing mechanism, the movement of the second door starts simultaneously with the opening operation of the first door, so that the behavior of the second door can be further reduced. The gap provided between the door and the door can be reduced.

  In a sixth aspect based on the fifth aspect, the interlocking mechanism mechanically transmits an operation force for moving the first door from the first closed position to the first open position to the second door. Thus, the sliding door opening / closing mechanism is characterized in that the second door is moved.

  According to the opening / closing mechanism for the sliding door, the structure of the interlocking mechanism for moving the second door simultaneously with the start of the movement of the first door from the first closing position to the first opening position can be realized with a simple structure. it can.

  In a seventh aspect based on any one of the first to sixth aspects, the second supporting portion slides the second door between the second closing position and the second opening position. Supporting the second door at the second open position and overlapping the first door back and forth, wherein the interlocking mechanism is interlocked with the movement of the second door from the second closed position to the second open position. And opening and closing the sliding door, wherein the first door is moved so as to avoid interference with the second door.

  According to the opening / closing mechanism for the sliding door, both the first door and the second door are slidable, and the first door is moved in conjunction with the movement of the second door, thereby further improving the usability of the sliding door. Can be done. For example, when the first door and the second door are vertically adjacent to each other and the first door and the second door are slid up and down, the first door and the second door are optimally adjusted to the height of the user. Two doors can be opened and closed. In addition, for example, when the first door and the second door are adjacent to each other on the left and right, and the first door and the second door are slid left and right, the door can be opened and closed from either the left or right, and the use place is limited. Can be suppressed.

  According to the aspect of the present invention, when fully closed, the adjacent first and second doors are in a flat state, and when the first door is opened, the first and second doors are overlapped back and forth. In the opening / closing mechanism of the sliding door, even if the gap provided between the first door and the second door at the time of full closing is reduced, interference between the first and second doors at the time of opening can be suppressed, and at the time of opening. The present invention provides a sliding door opening / closing mechanism capable of suppressing a decrease in design of the sliding door.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the drawings, similar components are denoted by the same reference numerals, and detailed description will be omitted as appropriate.

FIG. 1 is a perspective view schematically illustrating a cabinet provided with a sliding door and an opening / closing mechanism thereof according to the embodiment.
As shown in FIG. 1, the cabinet 10 includes a storage shelf 12, a slide door 14, and an opening / closing mechanism 16.

  The storage shelf 12 has an open box shape with an open front. The storage shelf 12 has, for example, a substantially rectangular open box shape. The storage shelf 12 has a storage space SP (see FIG. 2) with an open front, so that articles can be stored in the storage space SP.

  The cabinet 10 is, for example, a kitchen cabinet installed in a kitchen space. The cabinet 10 is installed, for example, as a rear storage behind a face-to-face system kitchen, and stores articles such as tableware and cooking utensils in a storage space SP.

  However, the use of the cabinet 10 is not limited to the above. The cabinet 10 may be, for example, a kitchen cabinet used by being incorporated in a system kitchen, such as below a sink or a counter of the system kitchen. The cabinet 10 is not limited to a kitchen cabinet, but may be any cabinet used for other purposes.

  The slide door 14 is provided in front of the storage shelf 12. Hereinafter, in the present specification, the direction in which the sliding door 14 is provided with respect to the storage shelf 12 is referred to as “front”, and the opposite direction is referred to as “rear”. The upper, lower, right, and left sides in the forward-facing state are referred to as “upper”, “lower”, “right side”, and “left side”, respectively. The front is, in other words, the direction in which the storage shelf 12 opens.

  The sliding door 14 has a first door 21 and a second door 22 adjacent to each other. In this example, the first door 21 and the second door 22 are vertically adjacent. The first door 21 and the second door 22 may be adjacent to each other in the left-right direction, for example.

  The first door 21 and the second door 22 are of a sliding type. However, in the sliding door 14, at least the first door 21 only needs to be a sliding type. The second door 22 may be, for example, a hinged door. Further, in this example, when the first door 21 and the second door 22 are vertically adjacent to each other, the lower side is the first door 21 and the upper side is the second door 22. Conversely, the upper side may be the first door 21 and the lower side may be the second door 22. When the first door 21 and the second door 22 are arranged in the left-right direction, the right side may be the first door 21 and the left side may be the first door 21.

  When the first door 21 and the second door 22 are slidable in the vertical direction, the cabinet 10 further includes, for example, a fall prevention mechanism (not shown). The fall prevention mechanism has, for example, a spring or the like, and balances the urging force of the spring or the like with the weight of the first door 21 and the second door 22 so that the first door 21 and the second door 22 can be moved vertically. So that it can be held in the position. However, the configuration of the fall prevention mechanism is not limited to this, and may be any configuration that can suppress sudden drop of the first door 21 and the second door 22 that slide up and down. Further, for example, when the first door 21 and the second door 22 are slid in the left-right direction, the drop prevention mechanism is unnecessary.

  The first door 21 has a front surface 21a facing forward. The second door 22 has a front surface 22a facing forward. The shape of the first door 21 and the second door 22 is, for example, a substantially rectangular shape corresponding to the shape of the storage shelf 12. The first door 21 and the second door 22 have, for example, a substantially rectangular plate shape.

  The thickness of each of the first door 21 and the second door 22 is, for example, 21 mm, and at that time, between the first door 21 and the second door 22 between the adjacent first door 21 and the second door 22. The gap GP in the adjacent direction (for example, the vertical direction) is about 5 mm (for example, 2 mm or more and 8 mm or less). In other words, the gap GP between the front surface 21a and the front surface 22a is about 5 mm. Thereby, a high design property can be obtained in the slide door 14.

  The first door 21 and the second door 22 cover the entire opening 12a (see FIG. 2) facing the front of the storage shelf 12 when fully closed. The first door 21 and the second door 22 move (open) from the fully closed position, thereby exposing a part of the opening 12a (storage space SP) of the storage shelf 12 to the front. Thus, by opening the first door 21 or the second door 22, it is possible to put articles in and out of the storage space SP of the storage shelf 12.

  The sliding door 14 is not limited to the two doors 21 and 22, and may have three or more doors. The cabinet 10 may further include a door other than the sliding door 14, a drawer, and the like. As described above, when the sliding door 14 has three or more doors or when the cabinet 10 further includes another door, the first door 21 and the second door 22 are in the storage shelves when fully closed. The cover 12 covers only a part of the opening 12a facing forward. That is, the first door 21 and the second door 22 may be configured to cover at least a part of the opening 12a facing the front of the storage shelf 12 when fully closed.

  The opening / closing mechanism 16 supports the first door 21 and the second door 22 so that they can be opened and closed. In other words, the opening / closing mechanism 16 supports the slidable first door 21 and second door 22 so as to be slidable. The opening and closing mechanism 16 is provided at the front end of the storage shelf 12. The slide door 14 is provided in front of the opening / closing mechanism 16. That is, the slide door 14 is provided in front of the storage shelf 12 via the opening / closing mechanism 16. The opening and closing mechanism 16 may be attached to the inside of the storage shelf 12, for example. The opening and closing mechanism 16 may be configured to be able to open and close the first door 21 and the second door 22 in front of the storage shelf 12.

  When the first door 21 and the second door 22 are fully closed, the opening / closing mechanism 16 makes the adjacent first and second doors 21 and 22 flat. Further, when the first door 21 or the second door 22 is opened, the opening / closing mechanism 16 overlaps the first door 21 and the second door 22 in the front-back direction.

  Here, the “flat state” refers to, for example, the position in the front-rear direction between the front surface 21a of the first door 21 and the front surface 22a of the second door 22 in a portion adjacent to the first door 21 and the second door 22. The difference is 5 mm or less. In this example, for example, the difference between the front and rear positions of the front surface 21a and the front surface 22a at the upper end of the front surface 21a and the lower end of the front surface 22a is 5 mm or less. For example, when the first door 21 and the second door 22 are arranged side by side in the left-right direction, the adjacent portions of the first door 21 and the second door 22 are the left and right ends of the front surfaces 21a and 22a.

FIGS. 2A to 2D are side views schematically illustrating a cabinet provided with a sliding door and an opening / closing mechanism thereof according to the embodiment.
As shown in FIGS. 2A to 2D, the storage shelf 12 has, for example, a shelf plate 12b. The shelf board 12b is provided in the storage space SP of the storage shelf 12, and divides the storage space SP into a first space SP1 and a second space SP2 by dividing the storage space SP up and down. The second space SP2 is provided above the first space SP1. The first space SP1 is, in other words, a lower storage space. The second space SP2 is, in other words, an upper storage space. The shelf board 12b is provided as needed and can be omitted. For example, in a case where the first door 21 and the second door 22 are arranged side by side, the shelf board 12b may not be provided.

  The opening / closing mechanism 16 includes a first support part 31, a second support part 32, and an interlocking mechanism. 2 (a) to 2 (d), some illustrations of the storage shelf 12 and the opening / closing mechanism 16 are omitted for convenience. Specifically, the illustration of the side panel 12c of the storage shelf 12 and the side panel 36 of the opening / closing mechanism 16 (all shown in FIG. 1) are omitted for convenience. The side panel 36 is provided on the side of the first support portion 31, the second support portion 32, and the interlocking mechanism 34, and suppresses these from being exposed to the side. 2 (a) to 2 (d), for the sake of simplicity, hatching is applied to the side end surface of the storage shelf 12 from which the side panel 12c is omitted for convenience.

  The first support portion 31, the second support portion 32, and the interlocking mechanism 34 are provided at both ends of the storage shelf 12 and the slide door 14 in the left-right direction. That is, the opening / closing mechanism 16 includes a pair of first support portions 31 provided at both left and right ends of the storage shelf 12 and the slide door 14, a pair of second support portions 32, and a pair of interlocking mechanisms 34. .

  For example, when the first door 21 and the second door 22 slide in the left-right direction, the first support portion 31, the second support portion 32, and the interlocking mechanism 34 move the storage shelf 12 and the slide door 14 up and down. Are provided at both ends. As described above, the first support portion 31, the second support portion 32, and the interlocking mechanism 34 are provided on the storage shelf 12 and the slide door 14 in the direction orthogonal to the direction of the sliding movement of the first door 21 and the second door 22. It is provided at both ends.

  However, the number of each of the first support portion 31, the second support portion 32, and the interlocking mechanism 34 is not limited to two, but may be one, or may be three or more. The numbers of the first support portions 31, the second support portions 32, and the interlocking mechanisms 34 may be different among the first support portions 31, the second support portions 32, and the interlocking mechanisms 34.

  The pair of first support portions 31 provided at both ends of the storage shelf 12 and the slide door 14 in the left-right direction have substantially the same configuration that is symmetrical in the left-right direction. The pair of second support portions 32 and the pair of interlocking mechanisms 34 are the same as the pair of first support portions 31. Therefore, the configuration of the first support portion 31, the second support portion 32, and the interlocking mechanism 34 in the left-right direction will be described below.

  The first support portion 31 is slidably movable between a first closed position (a position shown in FIG. 2A) and a first open position (a position shown in FIG. 2C). , And the first door 21 overlaps the second door 22 in the front and rear directions at the first opening position.

  The second support portion 32 moves the second door 22 so as to be movable between a second closed position (the position shown in FIG. 2A) and a second open position (the position shown in FIG. 2D). To support. In this example, the second support portion 32 supports the second door 22 so as to be slidable between a second closed position and a second open position, and moves the second door 22 to the first door 21 in the second open position. And overlap back and forth. For example, when the second door 22 is a hinge type, the second support portion 32 supports the second door 22 so as to be rotatable between a second closed position and a second open position.

  When the first door 21 is in the first closed position, the front of the first space SP1 is covered by the first door 21. Then, in a state where the first door 21 is at the first open position, the first space SP1 is opened forward. Thus, by moving the first door 21 to the first open position, articles can be taken in and out of the first space SP1.

  Similarly, when the second door 22 is in the second closed position, the front of the second space SP2 is covered by the second door 22. Then, in a state where the second door 22 is at the second open position, the second space SP2 is opened forward. Thus, by moving the second door 22 to the second open position, articles can be taken in and out of the second space SP2.

  The first support portion 31 moves the first door 21 from the first closed position to the first open position only by operating the first door 21 toward the second door 22 and moves the first door 21 to the second open position. The first door 21 is moved from the first open position to the first closed position only by an operation in a direction to separate from the door 22. That is, in this example, only the operation of moving the first door 21 upward, the first door 21 moves from the first closed position to the first open position, and only the operation of moving the first door 21 downward, The first door 21 moves from the first open position to the first closed position.

  The second support portion 32 moves the second door 22 from the second closed position to the second open position only by operating the second door 22 in a direction to approach the first door 21, and moves the second door 22 to the first open position. The second door 22 is moved from the second open position to the second closed position only by an operation in a direction to separate from the door 21. That is, in this example, only the operation of moving the second door 22 downward, the second door 22 moves from the second closed position to the second open position, and only the operation of moving the second door 22 upward, The second door 22 moves from the second open position to the second closed position.

  The first door 21 has a first side end face 21b facing the second door 22 at the second closed position when in the first closed position. In this example, the first side end surface 21b is, in other words, the upper end surface of the first door 21. The first side end surface 21b is, for example, substantially orthogonal to the front surface 21a of the first door 21. “Substantially orthogonal” means, for example, a state in which the angle between the front surface 21 a and the first side end surface 21 b is 88 ° or more and 92 ° or less.

  In addition, for example, an inclined surface or a curved chamfer may be provided between the front surface 21a and the first side end surface 21b. In addition, if the gap between the front surface 21a and the front surface 22a is provided to be small, the first side end surface 21b is not limited to a plane substantially orthogonal to the front surface 21a, and may be, for example, a curved surface. Is also good.

  The second door 22 has a second side end surface 22b facing the first side end surface 21b of the first door 21 at the first closed position when in the second closed position. In this example, the second side end surface 22b is, in other words, the lower end surface of the second door 22. The second side end face 22b is, for example, substantially perpendicular to the front face 22a of the second door 22. Hereinafter, since the second side end surface 22b is the same as the first side end surface 21b, detailed description will be omitted.

  The first support portion 31 supports an end of the first door 21 opposite to the first side end surface 21b. The first support portion 31 supports, for example, a lower end portion of the first door 21. The second support portion 32 supports an end of the second door 22 opposite to the second side end surface 22b. The second support portion 32 supports, for example, the upper end of the second door 22.

  The first support portion 31 supports, for example, the first door 21 so as to be slidable, and rotates the first door 21 about the front-rear direction and the direction orthogonal to the direction of the sliding movement of the first door 21. Support as much as possible. That is, in this example, the first support portion 31 rotatably supports the first door 21 about a left-right direction orthogonal to the front-rear direction and the up-down direction. Similarly, the second support portion 32 supports the second door 22 so as to be slidable, and also supports the second door 22 so as to be rotatable about the left-right direction. Thus, in the opening / closing mechanism 16, as shown in FIGS. 2B to 2D, the first door 21 can be tilted by rotating the lower end of the first door 21 about the axis. The second door 22 can be tilted by rotating the upper end of the second door 22 about an axis.

  The interlocking mechanism 34 interlocks with the movement of the first door 21 from the first closed position to the first open position as shown in FIG. 2B, and the second interlock mechanism 34 avoids interference with the first door 21. The door 22 is moved. Thus, interference between the first door 21 and the second door 22 due to the movement of the first door 21 can be suppressed.

  The interlocking mechanism 34 moves the first door 21 so as to avoid the interference with the second door 22 by interlocking with the movement of the second door 22 from the second closed position to the second open position. Thereby, interference between the first door 21 and the second door 22 due to the movement of the second door 22 can also be suppressed. The operation of moving the first door 21 in conjunction with the second door 22 is substantially the same as the operation of moving the second door 22 in conjunction with the first door 21. Therefore, hereinafter, the case where the first door 21 is moved will be described as an example.

  The interlocking mechanism 34 moves the first side end surface 21b back and forth from the second side end surface 22b in accordance with the movement of the first door 21 from the first closed position to the first open position, as shown in FIG. The first door 21 is tilted so as to be spaced apart from the first side, and the second door 22 is moved so that the second door 22 is tilted so as to separate the second side end face 22b on the side opposite to the first side end face 21b. In other words, the interlocking mechanism 34 moves the first door 21 and the second door 22 to opposite sides in the front-rear direction according to the movement of the first door 21 from the first closed position to the first open position. When the interlocking mechanism 34 moves the first door 21 from the first closed position to the first open position, the interlocking mechanism 34 moves the first door 21 in the front-rear direction, and in a direction opposite to the movement of the first door 21 in the front-rear direction. Then, the second door 22 is moved.

  The interlocking mechanism 34 rotates the first door 21 about the first support portion 31 in accordance with the movement of the first door 21 from the first closed position to the first open position, for example. The first door 21 is inclined so that the end face 21b moves backward. Then, the interlocking mechanism 34 rotates the second door 22 about the second support portion 32 in accordance with, for example, the movement of the first door 21 from the first closed position to the first open position. The second door 22 is inclined so that the second side end surface 22b moves forward. In other words, the interlocking mechanism 34 inclines the second door 22 according to the inclination of the first door 21 so that the front surface 21a and the front surface 22a are substantially parallel. “Substantially parallel” means, for example, a state in which the angle between the front surface 21a and the front surface 22a is ± 2 ° or less.

  Thereby, while the behavior of the first door 21 and the behavior of the second door 22 are reduced, the amount of separation between the first side end face 21b and the second side end face 22b can be increased, and the first door 21 and the second door Interference with the door 22 can be suppressed more reliably.

  Further, when the first door 21 and the second door 22 are inclined as described above, it is not necessary to move the first door 21 back and forth, and the inclined first door 21 is moved upward as it is. Only by this, the first door 21 can be moved from the first closed position to the first opened position. As described above, the first door 21 is moved from the first closed position to the first open position only by operating the first door 21 toward the second door 22 and the first door 21 is moved to the second door 22. The first door 21 can be moved from the first open position to the first closed position only by an operation in a direction of separating from the first door 21.

  As described above, for example, the interlocking mechanism 34 moves the second door 22 so that the second side end surface 22b faces forward with respect to the upward movement of the first door 21, and inclines the second door 22. . When the second door 22 is moved in conjunction with the movement of the first door 21, the interlocking mechanism 34 moves in a direction different from the sliding direction in which the first door 21 moves from the first closed position to the first open position. The second door 22 is moved. However, the direction of movement of the second door 22 interlocked with the movement of the first door 21 may be any direction that can appropriately suppress interference with the first door 21.

  Further, the interlocking mechanism 34 moves the second door 22 simultaneously with the start of the movement of the first door 21 from the first closed position to the first open position.

The width in the front-rear direction of the groove 62a corresponds to the width (diameter) in the front-rear direction of the engagement protrusion 44a of the first arm 44. When the first door 21 is at the first closed position, the first movable portion 62 causes the groove 62a to face the protrusion 60c and engages with the engagement protrusion 44a inserted through the protrusion 60c. Further, the first movable portion 62 further has an engagement protrusion 62b provided on a side surface facing the outside of the storage space SP. The engagement protrusion 62b has, for example, a round bar shape.

  The first support main body 40 has an inclined contact surface 40 a that comes into contact with the first movable portion 62. The first support body 40 moves the first movable portion 62 rearward along the inclination of the contact surface 40a when the first door 21 moves from the first closed position to the first open position.

  The first cam plate 64 is, for example, a flat plate extending in the vertical direction. The first cam plate 64 is provided to face a side surface of the first base portion 60 facing the outside of the storage space SP. The first cam plate 64 is attached to the first base portion 60 so as to be movable in the vertical direction. The first cam plate 64 has a cam groove 64a extending substantially linearly in a direction inclined with respect to the vertical direction. The cam groove 64a is engaged with the engagement protrusion 62b of the first movable portion 62.

  The upper end of the first cam plate 64 is connected to the lower end of the connecting plate 80. The upper end of the connecting plate 80 is connected to the lower end of the second cam plate 74. Thus, the first cam plate 64 and the second cam plate 74 are connected via the connecting plate 80.

  The configuration of each of the second base portion 70, the second movable portion 72, and the second cam plate 74 is the same as the configuration of each of the first base portion 60, the first movable portion 62, and the first cam plate 64. .

  A groove 70b that is continuous with the second slide groove 82a of the second slide rail 82 is provided on a side surface 70a of the second base 70 that faces the inside of the storage space SP. The groove 70b extends in the up-down direction. In the vicinity of the upper end of the groove 70b, there is provided a projection 70c which projects rearward in a substantially triangular shape.

The second arm portion 54 has an engagement protrusion 54a protruding toward the outside of the storage space SP. The engagement protrusion 54a has, for example, a round bar shape. The engagement protrusion 54a is inserted through the projection 70c of the second base 70 when the second door 22 is at the second closed position.

  The second movable section 72 is attached to the second base section 70 so as to be movable in the front-rear direction. The second movable section 72 is arranged at a position facing the groove 70b and the projection 70c. The second movable portion 72 has a groove 72a provided on a side surface facing the inside of the storage space SP. The groove 72a extends in the up-down direction. The second movable portion 72 is attached to the second base portion 70 so as to be movable in the front-rear direction between a position where the groove 72a faces the groove 70b and a position where the groove 72a faces the protrusion 70c. The width in the front-rear direction of the groove 72a corresponds to the width (diameter) in the front-rear direction of the engagement protrusion 54a of the second arm 54. When the second door 22 is in the first closed position, the second movable portion 72 causes the groove portion 72a to face the protrusion 70c and engages with the engagement protrusion 54a inserted through the protrusion 70c. Further, the second movable portion 72 further includes an engagement protrusion 72b provided on a side surface facing the outside of the storage space SP. The engagement protrusion 72b has, for example, a round bar shape.

  The second support main body 50 has an inclined contact surface 50 a that contacts the second movable portion 72. When moving the second door 22 from the second closed position to the second open position, the second support main body 50 moves the second movable portion 72 forward along the inclination of the contact surface 50a.

8 to 11 are partial side views schematically showing an enlarged part of the opening / closing mechanism according to the embodiment.
8 to 11 schematically show a state in which the first door 21 has started to move from the first closed position toward the first open position. 8 to 11 correspond to the portions shown in FIGS. 3 to 6, respectively.

  As shown in FIGS. 8 and 9, when the first door 21 is moved from the first closed position to the first open position, the first support body 40 is moved with the upward movement of the first door 21. Move up. When the first support main body 40 moves upward, the first movable portion 62 moves rearward along the inclination of the contact surface 40a due to the contact between the contact surface 40a and the first movable portion 62.

  When the first movable portion 62 moves rearward, the first arm portion 44 moves rearward together with the first movable portion 62 by the engagement between the groove portion 62a and the engagement protrusion 44a. Accordingly, the first door 21 can be tilted such that the first door 21 rotates about the rotation shaft 42a of the first hinge portion 42 and the first side end surface 21b moves rearward.

  When the first movable portion 62 moves backward, the groove 62a is opposed to the groove 60b from the state where the groove 62a is opposed to the protrusion 60c. As a result, the engagement protrusion 44a of the first arm portion 44 enters the first slide groove 81a of the first slide rail 81 via the groove 60b, and the first door 21 moves upward along the first slide rail 81. It is possible to move to. Therefore, in the first support portion 31 and the interlocking mechanism 34, the first door 21 is moved from the first closed position to the first open position only by operating the first door 21 toward the second door 22. Can be.

  Further, when the first movable portion 62 moves backward, the first cam plate 64 moves upward due to the engagement between the engagement protrusion 62b of the first movable portion 62 and the cam groove 64a of the first cam plate 64. . When the first cam plate 64 rises, the second cam plate 74 also rises via the connecting plate 80. Thereby, it becomes possible to move the second door 22 simultaneously with the start of the movement of the first door 21 from the first closed position to the first open position.

  As shown in FIGS. 10 and 11, when the second cam plate 74 rises, the engagement between the cam groove 74 a of the second cam plate 74 and the engagement projection 72 b of the second movable portion 72 causes the second movable portion to move. 72 moves forward.

  When the second movable portion 72 moves forward, the engagement between the groove 72a of the second movable portion 72 and the engagement protrusion 54a of the second arm portion 54 causes the second arm portion 54 to move forward together with the second movable portion 72. Moving. Thereby, the second door 22 can be tilted such that the second door 22 rotates about the rotation axis 52a of the second hinge portion 52 and the second side end face 22b moves forward. That is, in conjunction with the movement of the first door 21 from the first closed position to the first open position, the second door 22 can be moved so as to avoid interference with the first door 21.

  In this manner, the interlocking mechanism 34 moves the second door 22 by mechanically transmitting the operation force of the movement of the first door 21 from the first closed position to the first open position to the second door 22. . When the first door 21 is moved from the first open position to the first closed position, the operation force of the movement of the first door 21 from the first open position to the first closed position is reduced by a mechanical operation in the reverse procedure. The second door 22 is transmitted to the second door 22 and returns to the second closed position from the position where the second door 22 has moved (in an inclined state). In the first support portion 31 and the interlocking mechanism 34, the first door 21 can be moved from the first open position to the first closed position only by an operation in a direction to separate the first door 21 from the second door 22. .

  When the second door 22 is moved from the second closed position to the second open position, the operating force for moving the second door 22 from the second closed position to the second open position is performed in the same procedure as described above. Is mechanically transmitted to the first door 21 and the first door 21 moves.

  When the second door 22 is moved from the second closed position to the second open position, the contact between the contact surface 50a and the second movable portion 72 is caused by the downward movement of the second support body 50. The second movable part 72 moves forward along the inclination of the contact surface 50a. When the second movable portion 72 moves forward, the groove 72a is opposed to the groove 70b from the state where the groove 72a is opposed to the protrusion 70c. As a result, the engagement protrusion 54a of the second arm portion 54 enters the second slide groove 82a of the second slide rail 82 via the groove 70b, and the second door 22 moves downward along the second slide rail 82. It is possible to move to.

  As described above, according to the opening / closing mechanism 16 of the slide door 14 according to the present embodiment, the movement of the first door 21 from the first closed position to the first open position is synchronized with the movement of the first door 21. Since the interlocking mechanism 34 that moves the second door 22 so as to avoid interference is provided, even if the gap GP provided between the first door 21 and the second door 22 is made small when the door is fully closed, the first door 21 is not opened when the door is opened. Interference between the door 21 and the second door 22 can be suppressed. For example, it is possible to set the gap GP to about 5 mm, and it is possible to obtain high design of the slide door 14 while suppressing interference between the first door 21 and the second door 22. Further, in the first door 21 and the second door 22, it is not necessary to form the side end surfaces 21b and 22b opposed to each other when the door is fully closed in an inclined shape. For example, each side end surface 21b, 22b of the 1st door 21 and the 2nd door 22 can be made into the surface substantially orthogonal to the front surfaces 21a, 22a. Therefore, it is possible to suppress a decrease in the design property at the time of opening.

  In the opening / closing mechanism 16, when the interlocking mechanism 34 moves the first door 21 from the first closed position to the first open position, the interlocking mechanism 34 moves the first door 21 in the front-rear direction, and also moves the first door 21 in the front-rear direction. The second door 22 is moved in a direction opposite to the movement of the second door 22. This makes it possible to suppress the behavior when the second door 22 is moved so as to avoid interference with the first door 21. For example, when the first door 21 is moved, it is possible to suppress that the second door 22 largely moves and gives an uncomfortable feeling to the user. Therefore, it is possible to reduce the gap GP provided between the first door 21 and the second door 22 when the door is fully closed, and it is possible to further improve the design. Further, even when the width (depth of the door) of each side end surface 21b, 22b of the first door 21 and the second door 22 is set to be large, interference between the doors can be avoided with a slight behavior. In addition, the movement of the first door 21 and the second door 22 in the front-rear direction is not limited to the movement of tilting the first door 21 and the second door 22, and the front surfaces 21a and 22a are kept in a substantially vertical state. The movement which slides the 1st door 21 and the 2nd door 22 back and forth may be sufficient. However, the direction in which the second door 22 moves may be the same as the direction in which the first door 21 slides. For example, when the first door 21 is slid upward, the second door 22 may be moved upward to suppress interference with the first door 21.

  Further, in the opening / closing mechanism 16, the first support portion 31 moves the first door 21 from the first closed position to the first open position only by an operation in a direction in which the first door 21 approaches the second door 22, The first door 21 is moved from the first open position to the first closed position only by an operation in a direction in which the first door 21 is separated from the second door 22. Accordingly, for example, an operation of sliding the first door 21 after pulling the first door 21 forward becomes unnecessary, and the opening and closing operation of the first door 21 can be simplified, and the usability of the slide door 14 can be improved. However, the first support portion 31 may have a configuration in which, for example, after the first door 21 is moved in the front-rear direction, the first door 21 is slid vertically.

  Further, in the opening / closing mechanism 16, the interlocking mechanism 34 moves the first side end face 21b forward and backward from the second side end face 22b in accordance with the movement of the first door 21 from the first closed position to the first open position. First, the first door 21 is tilted, and the second door 22 is moved to tilt the second door 22 so as to separate the second side end face 22b on the side opposite to the first side end face 21b. By inclining the first door 21 and the second door 22 in this manner, the behavior of the second door 22 can be further reduced, and between the first door 21 and the second door 22 when fully closed. The gap GP provided can be kept smaller. For example, even when the first door 21 can be opened and closed only by an operation in a direction to approach or separate from the second door 22, interference between the doors is suppressed only by tilting the first door 21 and the second door 22. It can be realized with a simple configuration. In addition, by reducing the behavior of the first door 21 and the second door 22, for example, it is possible to prevent the storage space of the storage shelf 12 from being pressed by the behavior of the first door 21 and the second door 22. it can.

  In the opening / closing mechanism 16, the interlocking mechanism 34 moves the second door 22 simultaneously with the start of the movement of the first door 21 from the first closed position to the first open position. Thereby, since the movement of the second door 22 starts simultaneously with the opening operation of the first door 21, it is possible to further reduce the behavior of the second door 22, and when the first door 21 and the second door 22 are fully closed. The gap GP provided between them can be kept smaller.

  Note that the start of the movement of the second door 22 does not necessarily have to be the same as the start of the movement of the first door 21. For example, when the first door 21 has moved to a predetermined position, the movement of the second door 22 may be started.

  Further, in the opening / closing mechanism 16, the interlocking mechanism 34 mechanically transmits the operation force of the movement of the first door 21 from the first closed position to the first open position to the second door 22, so that the second door 22 is moved. To move. Thereby, the structure of the interlocking mechanism 34 that moves the second door 22 simultaneously with the start of the movement of the first door 21 from the first closed position to the first open position can be realized with a simple structure.

  The mechanism for mechanically transmitting the operation force is not limited to the above, and may be any configuration capable of transmitting the operation force between the first door 21 and the second door 22. In addition, the interlocking mechanism 34 is not limited to the configuration that mechanically transmits the operating force. A configuration in which the two doors 22 are linked may be used.

  In the opening / closing mechanism 16, the interlocking mechanism 34 moves the first door 21 so as to avoid the interference with the second door 22 by interlocking with the movement of the second door 22 from the second closed position to the second open position. Let it. As described above, both the first door 21 and the second door 22 are slidable, and the usability of the slide door 14 is further improved by moving the first door 21 in conjunction with the movement of the second door 22. be able to. For example, when the first door 21 and the second door 22 are vertically adjacent to each other and the first door 21 and the second door 22 are slid up and down, the first door 21 and the second door 22 are moved at an optimum height according to the height of the user. The first door 21 and the second door 22 can be opened and closed. Also, for example, when the first door 21 and the second door 22 are adjacent to each other on the left and right, and the first door 21 and the second door 22 are slid left and right, it is possible to open and close from either the left or right. Limitation of the place can be suppressed.

FIG. 12 is a side view schematically illustrating a modification of the cabinet provided with the sliding door and the opening / closing mechanism thereof according to the embodiment.
In addition, the same reference numerals are given to those substantially the same in function and configuration as those of the above-described embodiment, and the detailed description is omitted.
In the above embodiment, the interlocking mechanism 34 rotates the first door 21 about the first support portion 31 in accordance with the movement of the first door 21 from the first closed position to the first open position, The first door 21 is tilted so that the first side end surface 21b moves rearward, and the second door 32 is pivoted about the second support portion 32 in accordance with the movement of the first door 21 from the first closed position to the first open position. By rotating the second door 22, the second door 22 is inclined so that the second side end face 22b moves forward.

  Contrary to the above, as shown in FIG. 12, the interlocking mechanism 34 moves the first door 21 about the first support portion 31 in accordance with the movement of the first door 21 from the first closed position to the first open position. By rotating the first door 21, the first door 21 is tilted so that the first side end face 21 b moves forward, and the first door 21 is moved in the first closed position from the first closed position to the first open position. The second door 22 may be tilted so that the second side end surface 22b moves rearward by rotating the second door 22 about the second support portion 32 as an axis.

FIGS. 13A to 13C are side views schematically illustrating modified examples of the cabinet having the sliding door and the opening / closing mechanism according to the embodiment.
As shown in FIGS. 13A to 13C, in this example, when the first support portion 31 moves the first door 21 from the first closed position to the first open position, the first support portion 31 obliquely moves forward. The first door 21 is moved upward. At the start of the movement from the first closed position to the first open position, the first support portion 31 moves the first door 21 forward to a position where interference with the second door 22 is avoided.

  At this time, the interlocking mechanism 34 moves the second door 22 upward in accordance with the movement of the first door 21 from the first closed position to the first open position. Thereby, when the first door 21 is moved obliquely forward and upward, interference between the first door 21 and the second door 22 can be suppressed. Thus, the direction of the movement of the second door 22 may be the same as the direction of the sliding movement of the first door 21.

  Further, by moving the first door 21 obliquely upward and forward, for example, the first door 21 is moved from the first closed position to the first open position only by an operation in a direction in which the first door 21 approaches the second door 22. Can also be moved to

FIGS. 14A to 14C are side views schematically illustrating modified examples of the cabinet having the sliding door and the opening / closing mechanism thereof according to the embodiment.
As shown in FIGS. 14A to 14C, also in this example, the first support portion 31 moves the first door 21 from the first closed position to the first open position when moving the first door 21 forward. The first door 21 is moved obliquely upward.

  The interlocking mechanism 34 moves the second door 22 backward according to the movement of the first door 21 from the first closed position to the first open position. This makes it possible to reduce the amount of forward movement of the first door 21 when the first door 21 is moved obliquely forward and upward.

  The direction of movement of the second door 22 when the first door 21 is moved from the first closed position to the first open position may be, for example, forward. As described above, the direction of movement of the second door 22 when the first door 21 is moved from the first closed position to the first open position is an arbitrary direction in which interference with the first door 21 can be appropriately suppressed. The direction is fine.
