Description

  The present invention relates to a door opening / closing mechanism, and more particularly to a door opening / closing mechanism for moving a door attached to an opening surface in a direction away from the opening surface and then sliding the door in parallel with the opening surface.

  JP-A-2002-295117 discloses a storage door opening / closing structure as one of door opening / closing mechanisms for opening / closing a door attached to a storage device or the like.

  This storage door opening / closing structure is such that the door body attached to the opening of the storage body having an opening in the front is pulled out to the front in a state parallel to the opening, and then the door body is parallel to the opening. It can be slid sideways and opened.

  In the conventional door opening / closing mechanism as described above, the door main body can be moved in two directions, a direction away from the opening and a direction parallel to the opening, but the movement in these two directions is restricted to each other. They can be performed independently and simultaneously. Therefore, for example, when opening a door body attached via a conventional door opening / closing mechanism, a lateral force parallel to the opening is slightly applied while the door body is moved forward from the opening. When added to the door body, the door body starts to slide sideways at the same time as it is pulled out from the opening of the door body. The same applies to the case where the door body is closed. Then, contrary to the user's intention, the movement of the door body becomes unstable, and it cannot be said that it is easy to use in terms of ease of opening and closing the door.

  The present invention has been made to solve the above-described problems, and the movement of the door body attached to the opening surface to a position parallel to the opening surface and the sliding in the direction parallel to the opening surface are both performed. It is an object to provide a door opening / closing mechanism that is easy to use and easy to use.

  In order to achieve the above object, an invention according to claim 1 is a door opening / closing mechanism that opens and closes a door body with respect to an opening surface, and supports the door body and covers at least a part of the opening surface. The support means that is movable between the state and the open state that is parallel to the opening surface and separated from the opening surface by a predetermined distance, and the door with respect to the support means for the first time when the door body moves to the open state. Slide means that allows the main body to slide in a direction parallel to the opening surface, and in response to the slide start of the door main body, the door main body is prevented from moving by the support means and the door main body returns from the slide state to the slide start state. Then, a blocking means for releasing the blocking of the movement of the door body is provided, and the sliding means is arranged on the back surface of the door body, has a slide plate having a flat plate portion orthogonal to the opening surface, and is fixed to the back surface, and its axial direction Slidable The support means comprises a portion that forms the opening surface and a parallel support link that connects the slide plate, and the support means includes at least one support link that forms the parallel support link. One end portion is pivotally attached to the flat plate portion, and the blocking means includes a notch formed at one end portion of at least one support link, and a rail guide that is movable in the axial direction of the rail according to the movement of the rail. And is attached to the flat plate portion so as to be rotatable between the first position and the second position, and engages with the rail guide without engaging with the notch at the first position, In this position, the lock arm engages with the notch without engaging with the rail guide, and the lock arm is maintained at the first position while the door body is in the closed state to the open state. When the movement is prevented and the door body is in the open state, the lock arm can move between the first position and the second position as the rail guide moves, and the door body is in the sliding state. The locking arm is maintained in the second position to prevent movement of the at least one support link.

  If comprised in this way, a slide of a door main body will be blocked | prevented until a door main body will be in an open state. Further, after the door body starts to slide, the movement of the door body toward the closed state is prevented. Furthermore, when the door body is returned to the slide start position, the door body can be moved to the closed state. Further, whether or not the support link can be moved is determined depending on whether or not the rail guide and the lock arm are engaged.

  The invention according to claim 2 is a door opening and closing mechanism that opens and closes the door body with respect to the opening surface, and supports the door body and covers at least a part of the opening surface, and is parallel to the opening surface. And the support means that is movable between the open state separated from the opening surface by a predetermined distance and the door body in the direction parallel to the opening surface with respect to the support means only when the door body moves to the open state. Slide means that can slide and allows the door body to slide in a plurality of specific open states with different distances from the opening surface, and prevents the movement of the door body by the support means in response to the sliding start of the door body When the door body returns from the sliding state to the sliding start state, the sliding body is provided with blocking means for releasing the blocking of the movement of the door body, and the sliding means is disposed on the back surface of the door body and is a flat plate portion orthogonal to the opening surface. Sula with And a rail that is fixed to the rear surface and engages with a part of the slide plate so as to be slidable in the axial direction, and the support means connects the slide plate and the portion that forms the opening surface. It comprises a parallel support link, one end of at least one support link constituting the parallel support link is rotatably attached to the flat plate portion, and the blocking means is intermittently provided at one end of at least one support link. A plurality of notches formed on the plate, a rail guide movable in the axial direction of the rail according to the movement of the rail, and attached to the flat plate portion so as to be rotatable between the first position and the second position. And a lock arm that engages with the rail guide without engaging with the notch at the first position, and engages with one of the notches without engaging with the rail guide at the second position. Between the closed state and the open state, the lock arm is maintained in the first position to prevent the rail guide from moving, and when the door body is in the open state, the lock arm is moved in accordance with the movement of the rail guide. When the door body is in a sliding state, the lock arm is maintained at the second position to prevent the movement of at least one support link.

  If comprised in this way, a slide of a door main body will be blocked | prevented until a door main body will be in an open state. Moreover, if the door body is in any position in a specific open state, the door body can be slid. Furthermore, after the door body starts to slide, movement in the direction orthogonal to the opening surface of the door body is prevented. Further, when the door body is returned to the sliding start state, the door body can be moved to another open state or closed state. Further, whether or not the support link can be moved is determined depending on whether or not the rail guide and the lock arm are engaged. Further, the position at which the door main body can slide changes depending on the number and position of the cutouts of the support link.

  As described above, since the invention according to claim 1 prevents the sliding of the door main body until the door main body is in the open state, the movement toward the open state and the sliding can be performed separately, It is easier to open the door body. In addition, since the door body is prevented from moving toward the closed state after the door body starts sliding, the door body is fixed in the open state and does not move unexpectedly, and the sliding operation is further facilitated. Furthermore, since the door body can be moved to the closed state when the door body is returned to the slide start position, the operation for returning the door body to the slide start position is separate from the operation for closing the door body to the closed state. It is possible to perform the operation to close the door body. Furthermore, since whether the support link can move or not is determined depending on whether or not the rail guide and the lock arm are engaged, the door body can be opened and closed and slid in the same manner stably and reliably.

  In the invention according to claim 2, since the sliding of the door main body is prevented until the door main body is in the open state, the movement toward the open state and the sliding can be performed separately, and the operation of opening the door main body is performed. It becomes easy to do. In addition, since the door body can be slid if the door body is in any specific open position, the user can select the position to slide the door body according to the usage state, improving usability. . Furthermore, after the door body starts sliding, movement in the direction orthogonal to the opening surface of the door body is prevented, so that the door body does not move unexpectedly, and the sliding operation is further facilitated. Further, when the door body is returned to the slide start state, the door body can be moved to another open state or a closed state, so that the operation of returning the door body to the slide start position and the other open state or The operation of moving to the closed state can be performed separately, and the operation of further opening and closing the door body is facilitated. Furthermore, since whether the support link can move or not is determined depending on whether or not the rail guide and the lock arm are engaged, the door body can be opened and closed and slid in the same manner stably and reliably. In addition, since the position at which the door body can be slid changes depending on the number and position of the cutouts of the support link, the position from the opening surface on which the door body can slide is set to a desired position depending on how the cutout is formed. It becomes possible.

  FIG. 1 is a front view showing a schematic configuration of a storage device using a door opening / closing mechanism according to a first embodiment of the present invention.

  Referring to the drawing, a storage device 1 connects a rectangular parallelepiped box-shaped storage body 4 having an opening surface whose front surface is open, a door body 2 covering the opening surface, and the door body 2 and the storage body 4. It is mainly composed of a pair of door opening / closing mechanisms 10a and 10b. The storage device 1 is used for storing articles in the storage body 4 in, for example, a kitchen or a front door. In addition, the handle 3 attached to the outer surface of the door main body 2 is for making it easy to open and close the door main body 2 at the time of use.

  The door opening / closing mechanisms 10a and 10b are configured to be line-symmetrical in the vertical direction, and are connected to each other in the vertical direction. Thus, by using the pair of door opening / closing mechanisms 10a and 10b connected in parallel, twisting and swinging of the door main body 2 during movement can be suppressed, and the opening / closing operation can be performed more stably. Since the configuration and operation of these door opening / closing mechanisms 10a and 10b are the same, only the door opening / closing mechanism 10a disposed on the lower side will be described in detail below.

  2 is an enlarged cross-sectional view taken along line II-II shown in FIG. 1, FIG. 3 is a cross-sectional view taken along line III-III shown in FIG. 2, and FIG. It is an expanded sectional view of IV line.

  With reference to these drawings, a base plate 15 is attached to the inner surface of the side plate 5 a of the storage body 4. The base plate 15 is formed such that, for example, a pair of flat plate portions 36a and 36b and a vertical portion 37 are formed by bending a metal plate, and a portion where the flat plate portions 36a and 36b are opposed has a U-shaped cross section. ing. The vertical portion 37 is fixed in a state where the outer surface thereof is in contact with the inner surface of the side plate 5a, and a part of the vertical portion 37 extends further upward and is connected to the other base plate forming a pair. The base plate 15 is for connecting each of one end portions of a parallel support link, which will be described later, to a side plate 5a that is a portion constituting an opening surface.

  On the back surface 6 side of the door body 2, sliding means mainly including a slide plate 16 and a rail 26 is configured. The rail 26 is formed in a linear shape having a U-shaped cross section, and is fixed to the back surface 6 of the door body 2 so as to extend in the horizontal direction so that the opened portion of the U-shape is on the storage body 4 side. . The vertical dimension inside the rail 26 is set to be slightly larger than the width in the same direction of the engaging portion 30 of the slide plate 16 described later.

  The slide plate 16 has a pair of opposed flat plate portions 34a and 34b and a vertical portion 35 formed by bending a metal plate, for example, and the cross section of the portion where the flat plate portions 34a and 34b face each other is U-shaped. It is configured. On the outer surface of the vertical portion 35, a linear engagement member 30 having a U-shaped cross section is fixed so as to extend in the horizontal direction.

  The slide plate 16 configured in this way is attached to the rail 26 so that the engaging portion 30 can slide inside the rail 26 on the back surface 6. Accordingly, the door body 2 can be slidably moved relative to the slide plate 16 together with the rail 26.

  A part of the vertical portion 35 of the slide plate 16 extends further upward and is connected to the slide plate of the other door opening / closing mechanism that forms a pair. Further, dampers 19a and 19b each provided with an elastic body such as rubber are formed at both edge portions in the horizontal direction of the vertical portion 35, respectively. These dampers 19a and 19b are attached to stop the sliding of the door body 2 at the sliding end.

  The parallel support link constituting the support means includes a front support link 11 and a rear support link 12, and is attached so as to be bridged between the slide plate 16 and the base plate 15. The front support link 11, which is one of the support links, is rotatably connected at its left end to the flat plate portion 36a of the base plate 15 via a pin 13a, and its right end is connected to the slide plate 16 via a pin 13b. The flat plate portion 34a is rotatably connected. The rear support link 12, which is the other support link, has a left end portion rotatably connected to the flat plate portion 36b of the base plate 15 via a pin 14a, and a right end portion that slides via the pin 14b. The plate 16 is rotatably connected to the flat plate portion 34b of the plate 16. Since the door main body 2 and the storage main body 4 are connected in this way, the door main body 2 is integrated with the slide plate 16 and is in a closed state covering the opening surface of the storage main body 4 and parallel to the opening surface. It is possible to move between the open state that is a predetermined distance away from the opening surface in the state.

  A lock plate 20 is attached to the upper surface of the end portion 43 of the front support link 11. The lock plate 20 has an arcuate outer peripheral edge 31 centering on the pin 13b, and the end of the outer peripheral edge 31 on the back surface 6 side is cut out to form a recess 41. By fixing the lock plate 20 to the upper surface of the front support link 11, a notch 23 surrounded by the recess 41 and the upper surface of the end portion 43 is formed in the front support link 11.

  A blocking means including a lock arm 21, a notch 23, and a rail guide 27 is formed on the flat plate portion 34 a of the slide plate 16.

  The lock arm 21 is rotatable via a shaft 22 at a position included in the same plane as the lock plate 20 on the front support link 11 on the outer surface (upper surface) of the flat plate portion 34 a of the slide plate 16. It is attached and biased clockwise in FIG. 2 about the shaft 22 by a biasing means (not shown). One part of the lock arm 21 extends from the shaft 22 toward the back surface 6 side, and an elongated notch 24 is formed at an end thereof. The other part of the lock arm 21 extends from the shaft 22 to the inside of the storage body 4 and is formed to be slightly tapered. The lock arm 21 can be engaged with the notch 23 to prevent the front support link 11 from moving, and can be engaged with the rail guide 27 in a direction parallel to the opening surface of the door body 2. It is comprised so that a movement can be blocked | prevented. The blocking operation by the lock arm 21 will be described later.

  The rail guide 27 is connected to an end of the rail 26 on the left side (side plate 5a side), and can move in the axial direction of the rail 26 according to the movement of the door body 2. The rail guide 27 includes a vertical portion 39 that extends in the vertical direction along the back surface 6, and a horizontal portion 38 that branches from the vertical portion 39 and extends in the horizontal direction along the back surface 6. The tip of the horizontal portion 38 is bent at a substantially right angle to form a bent portion 29. The position of the bent portion 29 is set to a position substantially included in the same plane as the lock arm 21 and is attached so as to be engageable with the notch 24 of the lock arm 21 as the door body 2 moves. The vertical portion 39 extends further upward and is connected to a pair of rails of a door opening / closing mechanism. A rail guide 28 is similarly attached to the other end of the rail 26 (on the side plate 5b side), and similarly extends vertically upward and is connected to the rail of the other door opening / closing mechanism that forms a pair.

  It should be noted that one end of the spring 17 is rotatably attached to the flat plate portion 34a of the base plate 15 via the pin 18a and the other end thereof is interposed via the pin 18b so as to be bridged between the base plate 15 and the slide plate 16. The slide plate 16 is rotatably attached to the flat plate portion 36a. The spring 17 further biases the door body 2 toward the opening surface when the door body 2 is closed with respect to the storage body 4, and further opens the door body 2 when the door body 2 is open. It is attached so as to bias 2. Thereby, the door main body 2 can be stably stopped in the closed state and the opened state, and the usability of the storage device 1 is improved.

  Here, the opening / closing and sliding operation of the door body 2 will be described.

  FIG. 5 is a diagram showing an outline of the opening / closing operation of the door body in the door opening / closing mechanism according to the first embodiment of the present invention.

  Referring to the drawing, first, when the door main body 2 is in a closed state covering the opening surface of the storage main body 4, each part is at a position indicated by a solid line in the figure. At this time, the lock arm 21 is in contact with the outer peripheral edge 31 of the lock plate 20 and is not engaged with the notch 23, and is maintained at the position of the solid line (first position) in the figure. Therefore, the movement of the front support link 11 around the pin 13b is not restricted, and the door body 2 can be moved in the direction of pulling out from the opening surface. At this time, the notch 24 of the lock arm 21 and the bent portion 29 of the rail guide 27 are engaged, but the lock arm 21 is prevented from rotating clockwise about the shaft 22 by the lock plate 20. Therefore, the engaged state between the notch 24 and the bent portion 29 is maintained. Thereby, the sliding operation | movement to the direction parallel to the opening surface of the door main body 2 is blocked | prevented, and the door main body 2 is maintained at the slide start position.

  Next, the door body 2 is moved to the position indicated by the broken line in the drawing so that the door body 2 is pulled out from the opening surface. At this time, even if the front support link 11 moves to the position indicated by the broken line, the lock arm 21 still abuts on the outer peripheral edge 31 of the lock plate 20, and the clockwise rotation around the shaft 22 is prevented. Yes. For this reason, the engagement state between the notch 24 of the lock arm 21 and the rail guide 27 does not change, and the door body 2 is still maintained in a sliding start state.

  When the door body 2 further moves in the opening direction and is in an open state separated from the opening surface by a predetermined amount, each part is in a position indicated by a two-dot chain line in the figure. Note that further movement of the door body 2 from this open state is prevented by a stopper means (not shown) or the like. At this time, the distal end portion 32 of the lock arm 21 is disengaged from the outer peripheral edge 31 of the lock plate 20, and the notch 23 formed in the front support link 11 and the distal end portion 32 face each other. Therefore, the lock arm 21 is movable in the clockwise direction in the drawing around the shaft 22 by the amount of the notch 23 from the position indicated by the two-dot chain line. On the other hand, the notch 24 of the lock arm 21 and the bent portion 29 of the rail guide 27 are engaged, but the lock arm 21 can be rotated clockwise about the shaft 22. If the left and right sides are slid to the left, the engagement state between the notch 24 and the bent portion 29 is released, and the rail guide 27 can move according to the door body 2 and the rail 26.

  FIG. 6 is a diagram showing an outline of the sliding operation of the door body in the door opening / closing mechanism according to the first embodiment of the present invention. Note that (1) in FIG. 6 shows a state in which the door body is moved to the open state, which is the same as that indicated by the two-dot chain line in FIG.

  With reference to (1) of FIG. 6, when the door main body 2 is in an open state with respect to the opening surface and in a sliding start state, the lock arm 21 and the notch 23 do not engage with each other as described above. The distal end portion 32 of the arm 21 and the notch 23 face each other. At this time, the lock arm 21 is movable from the position shown in the figure (first position) to the second position in the clockwise direction in the figure centering on the shaft 22.

  When the door body 2 starts to slide to the left from this state, the door body 2, the rail 26, and the rail guide 27 move together to the left. As described above, since the lock arm 21 is urged clockwise around the shaft 22, the lock arm 21 is attached as the bent portion 29 of the rail guide 27 moves to the left. The movement starts in the direction of the arrow about the shaft 22 according to the force.

  When the door body 2 changes from the slide start state to the slide state, the lock arm 21 moves clockwise around the shaft 22 to the second position as shown in FIG. 32 and the notch 23 of the front support link 11 are engaged. In this state, if the door main body 2 is moved to the closed state, the front support link 11 tends to rotate counterclockwise in the drawing around the pin 13b. Therefore, the lock plate 20 also tries to rotate counterclockwise around the pin 13b.

  However, since the notch 23 and the lock arm 21 are in the engaged state, the lock arm 21 is prevented from rotating counterclockwise around the pin 13 b of the lock plate 20. That is, since the counterclockwise rotation around the pin 13b of the front support link 11 is also prevented, the door body 2 is prevented from moving toward the closed state.

  At this time, the direction of the force transmitted from the lock plate 20 to the lock arm 21 is configured to be in the direction of the shaft 22 of the lock arm 21. The second position is maintained without rotating around 22. Therefore, the front support link 11 is continuously prevented from rotating about the pin 13b.

  Then, as shown in FIG. 6 (3), when the door body 2 is slid leftward to the slide end, the rail guide 28 connected to the rail 26 and the damper 19b come into contact with each other and the movement stops. Even in this state, since the engagement state between the lock arm 21 and the front support link 11 is maintained, the movement of the door body 2 toward the closed state is prevented.

  In addition, in order to close the door main body 2 after storing a to-be-stored object in a storage main body, the operation mentioned above is performed in a reverse procedure. That is, the door body 2 is slid rightward until the rail guide 27 and the damper 19a come into contact with each other to return to the sliding start state ((1) in FIG. 6). Then, the bent portion 29 of the rail guide 27 engages with the notch 24 of the lock arm 21 and moves the lock arm 21 around the shaft 22 to the first position against the urging force in the clockwise direction. Move. As a result, the engagement state between the distal end portion 32 of the lock arm 21 and the notch 23 is released, and the front support link 11 is rotatable about the pin 13b. With the front support link 11 being rotatable, the door body 2 can be moved until the front support link 11 is in a closed state covering the opening surface.

  Since the door opening / closing mechanism 10a is configured as described above, while the door body 2 is in the closed state to the open state, the sliding of the door body 2 is blocked by the blocking means, and the first time when the door body 2 is opened. Is possible. Therefore, the operation of moving the door body 2 to the open state and the slide can be performed separately, and the operation of opening the door body 2 is facilitated. Further, in response to the start of sliding of the door body 2, the movement of the front support link 11 that is a support means is prevented, so that the door body 2 does not move from the open state when the door body 2 slides, and the sliding operation is performed. Is even easier to do. Further, since the front support link 11 can be moved again when the door body 2 is returned to the slide start state, the operation of returning the door body 2 to the slide start state and the door body 2 are closed. The operation can be performed separately, and the operation of closing the door body 2 is facilitated. Since the blocking means is constituted by the lock arm, the notch of the front support link, and the rail guide, the movement control of the door body 2 as described above can always be stably performed in the same manner.

  FIG. 7 is a view showing an outline of the door body opening / closing operation in the door opening / closing mechanism according to the second embodiment of the present invention.

  First, the structure of the door opening / closing mechanism 10a will be described with reference to the portion indicated by the solid line in the figure. The basic configuration of the door opening / closing mechanism 10a according to this embodiment is the same as that according to the first embodiment, but the shape of the lock arm 21 constituting the blocking means and one end of the front support link 11 are the same. The number of notches formed in the portion 43 is different from that of the first embodiment.

  The lock arm 21 is formed such that a portion on the side of the storage body 4 from the shaft 22 is narrower than the other portion, and an engaging portion 42 that protrudes toward the end 43 side of the front support link 11 is formed at the tip. Yes.

  Further, the lock plate 20 is attached to the upper surface of the end portion 43 of the front support link 11 so as to be included in substantially the same plane as the lock arm 21. A plurality of notches 25 having a shape that can be engaged with the engaging portion 42 of the lock arm 21 are intermittently formed radially on the pin 13b in the arc-shaped outer peripheral edge 31 of the lock plate 20.

  Next, the opening / closing operation | movement of the door main body 2 is demonstrated.

  When the door body 2 is in the closed state, the lock arm 21 is not engaged with the front support link 11 and is maintained at the position indicated by the solid line (first position) in the figure. In this state, since the front support link 11 can rotate clockwise around the pin 13b, the door body 2 can be moved to the open state. In addition, the notch 24 of the lock arm 21 and the engaging portion 29 of the rail guide 27 are in an engaged state, but the rotation about the shaft 22 of the lock arm 21 is blocked by the lock plate 20, so the notch 24 And the rail guide 27 are maintained in an engaged state. Therefore, the door body 2 is prevented from sliding and is maintained in the sliding start state.

  When the door body 2 is moved from this state to the position indicated by the broken line so as to be pulled out from the opening surface, the engaging portion 42 of the lock arm 21 and the notch 25 face each other. Accordingly, the lock arm 21 can rotate clockwise from the first position indicated by the broken line by the notch 25 around the shaft 22. Further, although the notch 24 of the lock arm 21 and the rail guide 27 are engaged, the lock arm 21 is rotatable, so the engagement state between the notch 24 and the rail guide 27 is released, and the door body 2 is released. Can be slid leftward in the figure.

  Further, when the door body 2 is moved to the position indicated by the two-dot chain line so as to be pulled out, the engaging portion 42 of the lock arm 21 and the other notch of the front support link 11 face each other. In this state, similarly to the state shown by the broken line, the lock arm 21 can rotate clockwise about the shaft 22, so that the door body 2 can be slid leftward in the figure. is there.

  Thus, by forming the plurality of notches 25 in the end portion 43 of the front support link 11, the door body 2 can be placed in any one of the plurality of open states in which the engaging portion 42 and any one of the notches face each other. In this case, since the lock arm 21 can rotate from the first position to the second position, the door body 2 can be slid.

  FIG. 8 is a diagram showing an outline of the sliding operation of the door body in the door opening / closing mechanism according to the second embodiment of the present invention. Note that (1) in FIG. 8 corresponds to the one shown by the broken line in FIG.

  As described above, in the door opening / closing mechanism 10a according to this embodiment, the door main body 2 is slidable in a plurality of open states corresponding to the notches of the front support link 11, but the door main body in any open state. The sliding operation of 2 is almost the same. Therefore, here, only the sliding operation when the door body 2 is in the open state corresponding to the notch 25 will be described.

  With reference to (1) of FIG. 8, when the door main body 2 is in one open state, the engaging part 42 of the lock arm 21 and the notch 25 of the front support link are opposed to each other. When the door body 2 starts to slide in the left direction in the figure from this state, the engaging portion 29 of the rail guide 27 also moves in the left direction according to the door body 2. Also in the door opening / closing mechanism according to this embodiment, the lock arm 21 is urged by urging means (not shown), so that the lock arm 21 starts to rotate clockwise in the drawing around the shaft 22 according to the urging force.

  Further, when the door body 2 is moved leftward to be in a sliding state, the lock arm 21 is moved to the second position by the urging force of the urging means as shown in FIG. The engaging portion 42 and the notch 25 are engaged. At this time, even if the door body 2 is moved in either the closed state or the other open state, the lock arm 21 prevents rotation about the lock plate 20 and the pin 13 b of the front support link 11. Therefore, the door body 2 is prevented from moving.

The opening / closing mechanism may be used without being connected.

  Further, in each of the above-described embodiments, the notch of the blocking means is formed by attaching the lock plate to the upper surface of the front support link. However, the support link itself is not necessarily formed in this way. It may be formed.

  Further, in each of the above embodiments, the blocking means is configured to block the movement of the front support link in the sliding state of the door body, but is configured to be slidable only when the door body is open. If so, it is not always necessary to configure the blocking means so that the movement of the parallel support link can be blocked.

  Furthermore, in each of the above-described embodiments, the door opening / closing mechanism is applied so that the vertically installed door body is pulled out to the left front from the opening surface and slid in the left direction. For example, the door body may be slid in the right direction or the up-down direction, or the door body arranged in the horizontal direction may be slid.

  Furthermore, in each said embodiment, although the door opening / closing mechanism is applied to the storage apparatus used in a kitchen, it is applicable similarly to the door of other storage apparatuses, and doors other than a storage apparatus. .

  Furthermore, in each of the above-described embodiments, if a means for preventing the lock arm from exceeding the second position is further provided, the movement of the front support link is more firmly prevented, and the sliding state of the door body is improved. It becomes possible to make it more stable.

  Furthermore, in the first embodiment described above, a spring for stabilizing the stop state of the door body is attached, but it is not always necessary to have such a configuration, and the spring may not be provided.

  Furthermore, in the second embodiment, as in the first embodiment, it is also possible to attach a biasing means such as a spring for stabilizing the stop state of the door body.

  Furthermore, in the second embodiment described above, the plurality of notches in the front support link are intermittently formed radially, but it is not always necessary to configure in this manner, and the number, arrangement, and interval of the notches are arbitrary. Can be set.
