Description

  The present invention relates to a wall cabinet, and more particularly to a wall cabinet having a counter.

  Conventionally, a folding drainer shelf (counter) provided below a hanging cabinet has been known (see, for example, Patent Document 1). The folding drainer shelf is positioned below the hanging door shelf when used, and is stored in a fluorescent lamp box attached to the lower end of the hanging door shelf when folded.

  Moreover, what is provided with the raising / lowering shelf in the rear part in the hanging shelf arrange | positioned at the corner of a wall is known (for example, refer patent document 2).

Japanese Patent Laying-Open No. 2005-58471 (FIG. 10) Japanese Utility Model Publication 2-45035 (Fig. 1)

  In the hanging cabinet disclosed in Patent Document 1, the storage space of the draining shelf (counter) is located below the hanging cabinet, above all, so that it is the most frequently used and convenient in the storage space of the hanging cabinet. There is an essential disadvantage of sacrificing space. In addition, even when the draining shelf is stored or not stored, the draining shelf is always located under the fluorescent lamp, which may hinder illumination during operation. Moreover, the fluorescent lamp box for storing the draining shelf becomes large, the illumination may become far away, and the work space may become narrow, which may make it difficult for the operator to work.

  Since the lifting shelf of the hanging shelf disclosed in Patent Document 2 is intended for storage, it has side plates in the left and right and the rear three directions. For this reason, there is a restriction on the size of an object placed on the lifting shelf, and it may interfere with the work of placing or lowering the object on the lifting shelf. Therefore, the lifting shelf is not convenient for temporarily placing an object.

  Accordingly, an object of the present invention is to effectively use storage space and improve workability in a wall cabinet having a counter that can be temporarily used.

  In order to achieve the above object, a wall cabinet according to the present invention includes a cabinet body having a bottom surface, an upper position disposed in a rear portion of the cabinet body, and stored in the cabinet body, and below the bottom surface of the cabinet body. A support frame movable up and down between the extended lower position and a counter supported by the support frame, the counter being in a deployed position extending forward from the support frame when the support frame is in the lower position; And a folding position extending upward along the support frame, and can be stored in the cabinet body together with the support frame at the folding position, and further rotated from the folding position toward the unfolded position. To prevent the counter and the cabinet body from interfering with each other, the support frame is placed higher While moving downwardly to a predetermined vertical position, it is characterized by having a holding portion for preventing the pivot toward the deployed position from the holding and counter folded position counter.

  In the wall cabinet configured as described above, when the counter is used, the support frame is extended downward from the cabinet body by moving the support frame from the upper position stored in the cabinet body to the lower position. Next, the counter is rotated from the folding position extending upward to the unfolding position extending forward. Since the counter in the unfolded position extends forward from the support frame, it is in a position where it can be easily operated. Further, since the counter is stored in the rear part of the cabinet body, the space below the wall cabinet can be used effectively, and lighting is not hindered. As a result, the workability of the wall cabinet can be improved.

  Further, since the counter is stored in the rear part of the cabinet body at the folding position extending upward, the space required for storing the counter is reduced. Therefore, even if it is adopted not only for a wall cabinet attached to a corner of a wall, but also for a wall cabinet attached to a wall or a wall cabinet attached to a ceiling, it is possible to improve workability while effectively using the storage space. it can.

  Further, when the stored counter is lowered together with the support frame, the holding unit prevents the counter from rotating from the folding position toward the unfolded position until the support frame moves downward to a certain vertical position. Therefore, it is possible to prevent the counter and the cabinet body from interfering with each other.

  In the embodiment of the wall cabinet, preferably, the vertical position is a position where the support frame descends most downward.

  In the embodiment of the wall cabinet, preferably, the cabinet body has a guide rail attached to the rear part thereof, and the support frame has a slide frame attached to the guide rail so as to be slidable in the vertical direction, The holding portion has a hook attached to the slide frame so as to be pivotable about the pivot axis, and the hook has one side and the other side extending from the pivot axis, and the support frame is located at the upper position. When lowered from one side, one side of the hook is biased to a holding position that holds the counter in the folded position, thereby preventing the counter from rotating from the folded position toward the deployed position, and the support frame is When the hook is lowered to the vertical position, the hook receives a force on the other side to pivot the hook against the bias to the holding position on one side. By, released from the position folded counter.

  In the embodiment of the wall cabinet, preferably, the cabinet body has a guide rail attached to the rear part thereof, and the support frame has a slide frame attached to the guide rail so as to be movable in the vertical direction, The holding portion has a hook attached to the slide frame so as to be pivotable about the pivot axis, and the hook has one side and the other side extending from the pivot axis, and the support frame is located at the upper position. When descending from the other side of the hook, the other side of the hook is restrained from pivoting from the holding position which holds the counter in the folded position, so that the counter is moved from the folded position to the deployed position. When the support frame is lowered to the vertical position, the restriction on the other side of the hook is released. , It makes it possible to release from the position folded counter.

  As described above, according to the wall cabinet according to the present invention, it is possible to effectively use the storage space and improve workability in the wall cabinet having the counter that can be temporarily used.

  As shown in FIG. 4, the counter 6 has a plate shape, and a base portion 6 c is rotatably attached to the lower end portion of the slide frame 16. Thereby, when the support frame 4 is in the lower position 4b, the counter 6 extends upward from the base 6c along the support frame 4, that is, the unfolded position 6a extending forward in the horizontal direction from the base 6c. It can be rotated between the folding position 6b. Specifically, the counter 6 has a pivot shaft 6e that protrudes to the left at the base portion 6c, and the slide frame 16 is disposed on the left side of the counter 6 and at the lower end of the right plate portion 16b. , A rotation receiving portion 6f that rotatably supports the rotation shaft 6e is provided. Thus, the counter 6 is disposed between the left and right slide frames 16. The counter 6 can be stored in the rear storage portion 12b of the cabinet body 2 together with the support frame 4 at the folding position 6b.

  Further, the counter 6 preferably overlaps at least partially with the slide frame 16 when viewed from the left or the right when in the folding position 6b. In the present embodiment, the rotation receiving portion 6f is disposed at the center in the front-rear direction of the right plate portion 16b of the slide frame 16, so that the counter 6 at the folding position 6b extends from the base portion 6c to the distal end portion 6d. It is configured to overlap. It is preferable that the entire counter 6 at the folding position 6 b overlaps the slide frame 16 by making the thickness of the counter 6 smaller than the width in the front-rear direction of the right plate portion 16 b of the slide frame 16. Further, it is preferable that the counter 6 at the folding position 6b and the slide frame 16 extend in parallel.

  The bottom plate 18 of the support frame 4 functions as a stopper for the counter 6 at the deployed position 6a. A rotary damper (not shown) is preferably attached to the rotation shaft 6e.

  The counter 6 is preferably provided with an oblique support link 28 that obliquely connects the slide frame 16 and the counter 6. One end portion 28a of the oblique support link 28 has a pin 28c slidable along a guide hole 28b provided in the right plate portion 16b of the slide frame 16 and extending in the vertical direction, and the other end portion 28d is The counter 6 is pivotally mounted. The guide hole 28b may be used as a stopper at the development position 6a of the counter 6 by appropriately determining the position of the guide hole 28b.

  The bottom plate 18 of the support frame 4 has a stopper 32 that holds the support frame 4 at the upper position 4a. The stopper 32 is disposed at the center of the bottom plate 18 in the left-right direction and can be pivoted about a shaft 34a extending in the left-right direction. The stopper 32c is provided above the shaft 34a, and is provided below the shaft 34a. Lever part 32d. The rear plate 2d of the cabinet body 2 is provided with a notch 34b with which the hook 32c is engaged. The stopper 32 can be pivoted by a lever portion 32d between an engagement position 32a where the hook 32c engages with the notch 34b and a release position 32b where the hook 32c is separated from the notch 34b. The stopper 32 is preferably biased to the engagement position 32a.

  As shown in FIGS. 3, 6, and 7, the slide frame 16 has a holding portion 52 that holds the counter 6 at the folding position 6b. Therefore, the holding part 52 can move up and down together with the support frame 4 while holding the counter 6 in the folded position 6b. Specifically, the holding portion 52 is pivoted around the shaft 54b, a shaft bracket 54a extending leftward from the right plate portion 16b of the slide frame 16, a shaft 54b having a pivot axis extending in the front-rear direction from the shaft bracket 54a. And a movable hook 56.

  The hook 56 extends in the vertical direction, and has an upper portion 56c extending upward from the shaft 54b and a lower portion 56d extending downward therefrom. The upper part 56c has a hook upper protrusion 56e that protrudes toward the guide rail 14, and the guide rail 14 has a rail protrusion 58 that has an inclined surface that approaches the hook 56 as it goes downward. The protrusion 56e and the inclined surface of the rail protrusion 58 can be engaged with each other. The right plate portion 16b of the slide frame 16 has a hole 54c, and the lower portion 56d of the hook 56 has a hook lower protrusion 56f that penetrates the hole 54c. The hook lower protrusion 56f is provided with a receiving portion 56g that receives and holds the holding protrusion 31 of the counter 6. The receiving portion 56g can easily receive the holding projection 31 when the counter 6 moves from the deployed position 6a to the folding position 6b, but the holding projection 31 when the counter 6 moves from the folded position 6b to the deployed position 6a. Has a form that does not come off.

  The hook 56 can pivot between a holding position 56a that holds the counter 6 in the folding position 6b and a release position 56b that releases the counter 6 from the folding position 6b. The hook 56 is biased to the holding position 56a by a spring or the like (not shown).

  Specifically, when the support frame 4 is lowered from the upper position 4a, the hook 56 is in the holding position 56a. In the holding position 56 a, the hook upper protrusion 56 e is positioned above the rail protrusion 58 so as not to engage with the rail protrusion 58. The lower portion 56d of the hook 56 is in a position where the receiving portion 56g of the hook lower protrusion 56f is pivoted so as to pass through the hole 54c and receive the holding protrusion 31 of the counter 6 at the folding position 6b.

  Further, when the support frame 4 is lowered and moved to a position where the hook upper protrusion 56e and the rail protrusion 58 are engaged with each other, the hook 56 is in the release position 56b. At the release position 56b, the engagement between the hook upper protrusion 56e and the rail protrusion 58 causes the lower part 56d to move away from the holding protrusion 31 of the counter 6 in which the receiving part 56g of the hook lower protrusion 56f is in the folding position 6b. It is in the position pivoted to.

  The positional relationship between the hook upper protrusion 56e and the rail protrusion 58 is such that the counter 6 does not interfere with the cabinet body 2 when the hook 56 pivots to the release position 56b and releases the counter 6 from the folding position 6b. Determined. Within such a range, a plurality of rail protrusions 58 may be provided.

  Next, the operation and action of the wall cabinet according to the first embodiment of the present invention will be described.

  In a state where the support frame 4 is at the upper position 4a and the counter 6 is held at the folded position 6b by the holding portion 52, the lever portion 32d of the stopper 32 is pivoted from the engagement position 32a to the release position 32b. Accordingly, the support frame 4 is allowed to move downward while the counter 6 is held by the holding portion 52 in the folded position 6b.

  Next, the handle 22 is pulled downward to move the support frame 4 together with the counter 6 from the upper position 4a to the lower position 4b, for example, the lowermost position. As a modification, the support frame 4 may be slowly lowered by its own weight without pulling the handle 22 by adjusting a balance weight 26c and a rotary damper (not shown) attached to the pulley 26a.

  When the support frame 4 is in the upper position 4a and begins to descend from the position, the hook 56 is urged to the holding position 56a, and the holding projection 31 of the counter 6 is held by the receiving portion 56g, thus the counter 6 Is held in the folded position by the holding portion 52. Accordingly, the counter 6 is prevented from rotating from the folding position 6b toward the deployed position 6a, that is, the counter 6 cannot be rotated from the folded position 6b toward the deployed position 6a.

  When the support frame 4 is lowered while the counter 6 is held at the folded position 6b, the hook upper protrusion 56e engages with the inclined surface of the rail protrusion 58. When the support frame 4 is further lowered, the upper portion 56c of the hook 56 receives a force that pivots the hook 56 to the release position 56b against the force that urges the hook 56 to the holding position 56a, and thereby holds the hook 56 in the holding position. Pivot from 56a to release position 56b. Thereby, the hook lower protrusion 56 f moves away from the holding protrusion 31 of the counter 6. As a result, the holding projection 31 is disengaged from the receiving portion 56g, and the counter 6 can be released from the folding position 6b. The support frame 4 is preferably configured to be in the lowest position when the counter 6 is released from the folding position 6 b and the hook upper protrusion 56 e is engaged with the rail inclined surface 58.

  Next, the counter 6 is rotated from the folding position 6b to the unfolding position 6a. Specifically, the counter 6 may be moved by hand, or by adjusting a rotary damper (not shown) or the like attached to the rotating shaft 6e, the counter 6 slowly moves to the deployment position 6a by its own weight. You may comprise so that it may move. Thus, the counter 6 can be used.

  When the support frame 4 and the counter 6 are stored in the rear storage portion 12b, the counter 6 is rotated from the deployed position 6a to the folding position 6b. When the support frame 4 is lifted while the counter 6 is maintained in the folded position 6b by hand, the hook 56 is pivoted to the holding position 56a by a spring (not shown), and the receiving portion 56g holding projection 31 of the hook 56 is held. Fits into. As a modification, the counter 6 is slightly lifted while maintaining the counter 6 in the unfolded position 6a, and the hook 56 is pivoted to the holding position 56a by a spring (not shown), and then the counter 6 is folded from the unfolded position 6a to the folded position 6b. And may be fitted by being pushed into the receiving portion 56g.

  Next, when the support frame 4 is lifted while the counter 6 is held at the folding position 6b by the holding portion 52, the hook portion 32c of the stopper 32 is engaged with the notch 34b, and the support frame 4 is maintained at the upper position 4a. Is done. During this time, the hook 56 is biased to the holding position 56a by a spring (not shown), and has the same effect as when the counter 6 is lowered.

  In the wall cabinet 1 described above, since the holding portion 52 is attached to the support frame 4, the counter 6 can be stored and lowered together with the support frame 4 while being held by the holding portion 52 in the folded position 6b. Thus, interference between the counter 6 and the cabinet body 2 can be prevented, and the counter 6 and the support frame 4 can be stored and lowered smoothly.

  Further, in the wall cabinet 1 described above, the counter 6 is at least partially overlapped with the slide frame 16 when viewed from the left or right when in the folding position 6b. Can be small.

  Further, the holding unit 52 holds the counter 6 while the support frame 4 is moved downward to the vertical position where the hook upper protrusion 56e and the rail inclined surface 58 engage with each other, and is deployed from the folding position 6b. The rotation toward the position 6a is prevented, thereby preventing the counter 6 that rotates from the folding position 6b toward the deployment position 6a and the cabinet body 2 from interfering with each other.

  Further, when the counter is deployed after the support frame 4 is lowered to the lowest position, the counter is prevented from suddenly descending when an object is placed thereon, and the safety of the counter 6 can be ensured. .

  Next, with reference to FIGS. 8-10, 2nd Embodiment of the wall cabinet by this invention is described. The wall cabinet of the second embodiment has the same structure as the wall cabinet of the first embodiment except for the holding unit 72. Therefore, only different parts will be described below. FIG. 8 is a cross-sectional view similar to FIG. 3 in the wall cabinet of the second embodiment. 9 is a cross-sectional view taken along line IX-IX in FIG. 10 is a cross-sectional view taken along line XX in FIG.

  As shown in FIGS. 8-10, the slide frame 16 of the wall cabinet 70 which is the 2nd Embodiment of this invention has the holding | maintenance part 72 which hold | maintains the counter 6 in the folding position 6b. Accordingly, the holding portion 72 can move up and down together with the support frame 4 while holding the counter 6 at the folding position 6b. Specifically, the holding portion 72 includes slide bar brackets 74a and 74b fixed to the slide frame 16 with an interval in the vertical direction, and a slide shaft 76 supported by the slide shaft bracket 74a so as to be slidable in the vertical direction. The slide shaft 76 is pivotally attached to the lower end portion of the slide shaft 76 and has a link hook 78 engageable with the pin 28c of one end portion 28a of the oblique support link 28.

  The slide shaft 76 has an enlarged diameter portion 76c between the slide shaft brackets 74a and 74b, and a spring 76d is disposed between the upper slide shaft bracket 74a and the enlarged diameter portion 76c. Thereby, the slide shaft 76 is urged to the holding position 76a, that is, downward.

  The upper end of the slide shaft 76 has a slide shaft protrusion 76 e that protrudes toward the guide rail 14, and the guide rail 14 has a rail protrusion 80 that protrudes toward the slide shaft 76. The slide shaft protrusion 76e is located above the rail protrusion 80, and both can be engaged with each other.

  The link hook 78 is pivotable about a shaft 74c having a pivot axis extending from the left plate portion 16a of the slide frame 16, and extends from the shaft 74c to both sides. One side 78e of the link hook 78 is engageable with a notch 28e provided below the pin 28c of the oblique support link 28. The other side 78c of the link hook 78 is pivotally attached to the lower end of the slide shaft 76 via a shaft 78d.

  The slide shaft 76 and the link hook 78 are respectively slidable or pivotable between holding positions 76a and 78a for holding the counter 6 in the folding position 6b and release positions 76b and 78b for releasing the counter 6 from the folding position 6b. Is possible.

  Specifically, when the support frame 4 is lowered from the upper position 4a, the slide shaft 76 is urged to the holding position 76a by the spring 76d, and the slide shaft protrusion 76e is positioned above the rail protrusion 80. The link hook 78 is urged to the holding position 78a by the slide shaft 76, and one side 78e of the link hook 78 is in a position to engage with the notch 28e of the pin 28c of the oblique support link 28, thereby The pin 28c is prevented from sliding along the guide hole 28b.

  Further, when the support frame 4 is lowered and moved to a position where the slide shaft protrusion 76e and the rail protrusion 80 are engaged, the slide shaft 76 is in the release position 76b. In the release position 76b, the enlarged diameter portion 76c of the slide shaft 76 moves upward with respect to the slide shaft brackets 74a and 74b, whereby the link hook 78 pivots to the release position 78b. One side 78e of the link hook 78 is in a position retracted from the notch 28e of the pin 28c, thereby allowing the pin 28c to slide along the guide hole 28b.

  The positional relationship between the slide shaft projecting portion 76e and the rail projecting portion 80 is such that when the slide shaft 76 is moved between the release positions 76b and the link hook 78 is pivoted to the release position 78b, the counter 6 is moved to the cabinet body 2. It is determined not to interfere with.

  Next, the operation and action of the wall cabinet of the second embodiment will be described. Hereinafter, only the parts different from the operation and action of the wall cabinet of the first embodiment will be described.

  In a state where the support frame 4 is at the upper position 4a and the counter 6 is held at the folded position 6b by the holding portion 72, the lever portion 32d of the stopper 32 is pivoted from the engagement position 32a to the release position 32b. Accordingly, the support frame 4 is allowed to move downward while the counter 6 is held at the folding position 6b by the holding portion 72.

  When the support frame 4 is in the upper position 4a and begins to descend from it, the slide shaft 76 and the link hook 78 are biased to the holding positions 76a and 78a, and one side 78e of the link hook 78 is connected to the pin 28c. Since it engages with the notch 28e, the movement of the pin 28c of the diagonal support link 28 attached to the counter 6 is prevented. Thus, the counter 6 is held in the folded position by the holding portion 72. Accordingly, the counter 6 is prevented from rotating from the folding position 6b toward the deployed position 6a, that is, the counter 6 cannot be rotated from the folded position 6b toward the deployed position 6a.

  When the support frame 4 is lowered while the counter 6 is held at the folding position 6b, the slide shaft protrusion 76e engages with the rail protrusion 80. When the support frame 4 is further lowered, the slide shaft 76 moves upward with respect to the slide frame 16 and moves to the release position 76b. As a result, the other side 78c of the link hook 78 receives, via the slide shaft 76, a force that pivots the link hook 78 to the release position 78b against the force that biases the link hook 78 to the holding position 78a. The link hook 78 is pivoted to the release position 78b. Thereby, one side 78e of the link hook 78 moves away from the notch 28e of the pin 28c of the diagonal support link 28. As a result, the pin 28c is allowed to slide along the guide groove 28b, and the counter 6 can be released from the folding position 6b. The support frame 4 is preferably configured to be in the lowest position when the counter 6 is released from the folding position 6 b and the slide shaft protrusion 76 e is engaged with the rail protrusion 80.

  Next, the counter 6 is rotated from the folding position 6b to the unfolding position 6a. Specifically, the counter 6 may be moved by hand, or by adjusting a rotary damper (not shown) or the like attached to the rotating shaft 6e, the counter 6 slowly moves to the deployment position 6a by its own weight. You may comprise so that it may move. Thus, the counter 6 can be used.

  When the support frame 4 and the counter 6 are stored in the rear storage portion 12b, the counter 6 is rotated from the deployed position 6a to the folding position 6b. The support frame 4 is lifted while keeping the counter 6 in the folding position 6b by hand. As the support frame 4 is lifted, the slide shaft protrusion 76e moves away from the rail protrusion 80, and then the slide shaft 76 is moved downward with respect to the slide frame 16 by the spring 76d and finally moved to the holding position 76a. To do. Thereby, the other side 78c of the link hook 78 pivots the link hook 78 to the holding position 78a. One side 78e of the link hook 78 engages with the notch 28e of the pin 28c of the diagonal support link 28. As a result, the pin 28c is prevented from sliding along the guide groove 28b, and the counter 6 is folded. It becomes impossible to release from 6b.

  Next, when the support frame 4 is lifted while the counter 6 is held at the folding position 6b by the holding portion 72, the hook portion 32c of the stopper 32 is engaged with the notch 34b, and the support frame 4 is maintained at the upper position 4a. Is done. During this time, the slide shaft 76 and the link hook 78 are respectively urged to the holding positions 76a and 78a by the spring 76d, and the same effect as when the counter 6 is lowered is obtained.

  In the wall cabinet 70 described above, since the holding portion 72 is attached to the support frame 4, the counter 6 can be stored and lowered together with the support frame 4 while being held in the folding position 6b by the holding portion 72. Thus, interference between the counter 6 and the cabinet body 2 can be prevented, and the counter 6 and the support frame 4 can be stored and lowered smoothly.

  Further, the holding portion 72 described above holds the counter 6 while the support frame 4 moves downward to the vertical position where the slide shaft protruding portion 76e engages with the rail protruding portion 80, and unfolds from the folding position 6b. The rotation toward the position 6a is prevented, thereby preventing the counter 6 that rotates from the folding position 6b toward the deployment position 6a and the cabinet body 2 from interfering with each other.

  Next, a third embodiment of a wall cabinet according to the present invention will be described with reference to FIGS. The wall cabinet of the third embodiment has the same structure as the wall cabinet of the first embodiment except for the holding unit 92. Therefore, only different parts will be described below. FIG. 11 is a cross-sectional view similar to FIG. 3 in the wall cabinet of the third embodiment. 12 is a cross-sectional view taken along line XII-XII in FIG. FIG. 13 is a view similar to FIG. 12 in which a later-described hook is in the release position, and FIG. 13 is a view similar to FIG. 12 in which a later-described hook is in the blocking position.

  As shown in FIGS. 11-14, the slide frame 16 of the wall cabinet 90 which is the 3rd Embodiment of this invention has the holding | maintenance part 92 which hold | maintains the counter 6 in the folding position 6b. Accordingly, the holding portion 92 can move up and down together with the support frame 4 while holding the counter 6 in the folded position 6b. Specifically, the holding portion 92 includes a shaft bracket 94a extending leftward from the right plate portion 16b of the slide frame 16, a shaft 94b having a pivot axis extending in the front-rear direction from the shaft bracket 94a, and pivoting about the shaft 94b. And a movable hook 96. Further, a hook restricting member 98 extending in the vertical direction is attached to the rear plate 2d with an appropriate distance C from the guide rail 14. Accordingly, the hook 96 is movable in the vertical direction with respect to the guide rail 14 and the hook restricting member 98.

  The hook 96 extends in the vertical direction and has an upper portion 96d extending upward from the shaft 94b and a lower portion 96e extending downward therefrom. A portion of the upper portion 96 d of the hook 96 can be positioned between the guide rail 14 and the hook restricting member 98. The dimension of the upper part 96d is set to a size that restricts the hook 96 from substantially pivoting when it is positioned between the guide rail 14 and the hook restricting member 98. The upper portion 96d of the hook 96 preferably has a hook upper protrusion 96f that protrudes toward the guide rail 14. The right plate portion 16b of the slide frame 16 has a hole 94c, and the lower portion 96e of the hook 96 has a hook lower protrusion 96g that penetrates the hole 94c. The hook lower protrusion 96g can be engaged with a hole 6g provided on the side surface of the counter 6. The hook lower protrusion 96g has a front inclined surface 96h inclined forward from the front-rear direction center toward the slide frame 16, and a rear inclination inclined rearward from the front-rear direction center toward the slide frame 16. And a surface 96i (see FIG. 11).

  The hook 96 has a holding position 96a (see FIG. 12) for holding the counter 6 in the folding position 6b, a release position 96b (see FIG. 13) for releasing the counter 6 from the folding position 6b, and moves the counter 6 to the folding position 6b. The hook 96 that can be pivoted between a blocking position 96c (see FIG. 14) that prevents the movement is biased toward the blocking position 96c by a spring or the like (not shown).

  Specifically, as shown in FIG. 12, when the support frame 4 is lowered from the upper position 4a, the hook 96 is in the holding position 96a. In the holding position 96 a, the hook lower protrusion 96 g is configured to extend beyond the hole 94 c of the slide frame 16 and into the hole 6 g of the counter 6. A part of the upper portion 96d of the hook 96 is located between the guide rail 14 and the hook restricting member 98 and is movable in the vertical direction. Further, the distance C between the guide rail 14 and the hook restricting member 98 is set to a dimension that prevents the upper portion 96d of the hook 96 positioned therebetween from substantially pivoting from the holding position 96a. Yes. Accordingly, the upper portion 96d of the hook is restricted so as to prevent the lower protrusion 96g of the hook from pivoting from the holding position 96a that holds the counter 6 at the folding position 6b.

  As shown in FIG. 13, when the support frame 4 is lowered and the upper portion 96d of the hook 96 is positioned below the hook restricting member 98, the hook 96 is in the release position 96b. In the release position 96b, the lower part 96e is in a position pivoted so that the hook lower protrusion 96g moves away from the hole 6g of the counter 6 in the folded position 6b.

  Further, as shown in FIG. 14, when the support frame 4 is lowered, the upper portion 96d of the hook 96 is located below the guide rail 14, and the counter 6 is deployed, the hook 96 is in the blocking position 96c. In the blocking position 96c, the hook 96 is in a position where its upper portion 96d is located below the guide rail 14 and pivoted toward the left plate portion 16a of the slide frame 16. Further, the hook lower protrusion 96g is configured to rotate beyond the depth position of the hole 6g of the counter 6 so that the hole 6g cannot receive the hook lower protrusion 96g.

  When the hook 96 moves from the holding position 96a to the release position 96b when the upper part 96d of the hook 96 moves downward with respect to the hook restricting member 98 and exceeds the lower end, the hook 96 moves from the holding position 96a to the release position 96b. The counter 6 moving from the folding position 6b toward the unfolding position 6a is determined so as not to interfere with the cabinet body 2. The vertical position of the lower end of the guide rail 14 is preferably the same as the vertical position of the lower end of the hook restricting member 98. Further, the position where the upper portion 96d of the hook 96 exceeds the lower ends of the guide rail 14 and the hook restricting member 98 is preferably the position moved to the lowest position.

  Next, the operation and action of the wall cabinet of the third embodiment will be described. Hereinafter, only the parts different from the operation and action of the wall cabinet of the first embodiment will be described.

  In a state where the support frame 4 is at the upper position 4a and the counter 6 is held at the folded position 6b by the holding portion 92, the lever portion 32d of the stopper 32 is pivoted from the engagement position 32a to the release position 32b. Accordingly, the support frame 4 is allowed to move downward while the counter 6 is held at the folding position 6b by the holding portion 92.

  When the support frame 4 is in the upper position 4a and when it begins to descend, the hook 96 is in the holding position 96a, and the guide rail 14 and the hook restricting member 98 prevent the hook 96 from pivoting. Thus, the counter 6 is held at the folding position 6b by the holding portion 92. Thereby, since the counter 6 is prevented from rotating from the folding position 6b toward the deployed position 6a, the counter 6 cannot be rotated from the folded position 6b toward the deployed position 6a.

  When the support frame 4 is lowered while the counter 6 is held at the folded position 6b, the hook upper protrusion 96e exceeds the lower ends of the guide rail 14 and the hook restricting member 98, and the hook 96 is moved to the release position 96b and the blocking position 96c. Can pivot.

  Next, the counter 6 is rotated from the folding position 6b to the unfolding position 6a. Specifically, when the counter 6 is pulled by hand, the counter 6 slides along the rear inclined surface 96i of the hook lower protrusion 96g, pushes the hook lower protrusion 96g toward the slide frame 16, and 96 is pivoted to the release position 96b against the biasing force of a spring (not shown) (see FIG. 13). Thereby, the counter 6 can be rotated from the folding position 6b to the unfolding position 6a. Thus, the counter 6 can be used.

  When the counter 6 is unfolded from the folding position 6b and the counter 6 moves away from the hook lower protrusion 96g, the hook 96 biased by the spring moves to the blocking position 96c. (See FIG. 14). When the support frame 4 is lifted in this state, the hook upper protrusion 96e of the hook 96 moved to the blocking position 96c comes into contact with the lower end of the guide rail 14, thereby preventing the support frame 4 from rising.

  When the support frame 4 and the counter 6 are stored in the rear storage portion 12b, the hook 96 is manually moved to the release position 96b against the urging force of a spring (not shown), and then the counter 6 is moved from the deployed position 6a. Turn to the folding position 6b. Thereafter, by releasing the hand from the hook 96, the hook 96 is moved to the holding position 96a by the urging force of a spring (not shown), and the counter 6 is held at the folding position 6b. As a modified example, the front inclined surface 96h of the hook 96 located at the blocking position 96c is engaged with the counter 6 that moves from the deployed position 6a to the folding position 6b, and the counter 6 is folded from the deployed position 6a to the folded position 6b. The counter 6 slides along the front inclined surface 96h of the hook lower protrusion 96g, pushes the hook lower protrusion 96g toward the slide frame 16, and pushes the hook 96 to a spring (not shown). ) May be pivoted to the release position 96b.

  Next, when the support frame 4 is lifted while the counter 6 is held at the folding position 6b by the holding portion 92, the hook portion 32c of the stopper 32 is engaged with the notch 34b, and the support frame 4 is maintained at the upper position 4a. Is done. During this time, the hook upper protrusion 96e moves upward between the guide rail 14 and the hook restricting member 98, and the hook 96 is maintained at the holding position 96a. The hook 96 at the holding position 96a has the same effect as when the counter 6 is lowered.

  In the wall cabinet 90 described above, since the holding portion 92 is attached to the support frame 4, the counter 6 can be stored and lowered together with the support frame 4 while being held by the holding portion 92 in the folded position 6b. Thus, interference between the counter 6 and the cabinet body 2 can be prevented, and the counter 6 and the support frame 4 can be stored and lowered smoothly.

  The holding portion 92 described above holds the counter 6 and unfolds from the folding position 6b while the support frame 4 moves downward to the vertical position where the hook upper protruding portion 96e exceeds the lower ends of the guide rail 14 and the hook regulating member 98. The rotation toward the position 6a is prevented, thereby preventing the counter 6 that rotates from the folding position 6b toward the deployment position 6a and the cabinet body 2 from interfering with each other. Further, when the counter 6 is not in the folding position 6b, the support frame 4 is prevented from moving toward the upper position. That is, if the counter is not lowered to a predetermined position, the counter does not expand, and if the counter is not folded, the support frame does not rise toward the upper position 4a.

  Next, with reference to FIGS. 15-17, the 4th Embodiment of the wall cabinet by this invention is described. The wall cabinet of the fourth embodiment has the same structure as the wall cabinet of the first embodiment except for the holding unit 112. Therefore, only different parts will be described below. FIG. 15 is a cross-sectional view similar to FIG. 3 in the wall cabinet of the fourth embodiment. 16 is a cross-sectional view taken along line XVI-XVI in FIG. 17 is a cross-sectional view taken along line XVII-XVII in FIG.

  As shown in FIGS. 15-17, the slide frame 16 of the wall cabinet 110 which is the 4th Embodiment of this invention has the holding | maintenance part 112 which hold | maintains the counter 6 in the folding position 6b. Accordingly, the holding unit 112 can move up and down together with the support frame 4 while holding the counter 6 in the folded position 6b. Specifically, the holding portion 112 includes a shaft 114a having a pivot axis extending leftward from the right plate portion 16b of the slide frame 16, and a rotary hook 116 pivotable about the shaft 114a.

  The rotary hook 116 has an upper part 116c that extends in the vertical direction and extends upward from the shaft 114a, and a lower part 116d that extends downward therefrom. The upper portion 116c of the rotary hook 116 has an upper protrusion 116e that protrudes toward the guide rail 14, and the guide rail 14 has a guide member 118 for guiding the upper protrusion 116e. The guide member 118 has a guide groove 118a that receives the upper protrusion 116e and guides it toward the rear plate 2d as it goes downward. The lower portion 116d of the rotary hook 116 has a lower protruding portion 116f that protrudes toward the rotating shaft 6e of the counter 6, and the rotating shaft 6e has a notch 6h that engages with the lower protruding portion 116f. ing.

  The rotary hook 116 can pivot between a holding position 116a for holding the counter 6 in the folding position 6b and a release position 116b for releasing the counter 6 from the folding position 6b. The rotary hook 116 is biased to the holding position 116a by a spring or the like (not shown).

  Specifically, when the support frame 4 is lowered from the upper position 4a, the rotary hook 116 is in the holding position 116a. In the holding position 116a, the upper protrusion 116e is located above and away from the guide groove 118a. The lower protrusion 116f is in a position in contact with the notch 6h of the rotating shaft 6e.

  When the support frame 4 is lowered and the upper protrusion 116e is received in the guide groove 118a and moves rearward, the rotary hook 116 is in the release position 116b. At the release position 116b, the lower protrusion 116f is pivoted away from the notch 6h of the rotation shaft 6e of the counter 6 at the folding position 6b by the engagement between the upper protrusion 116e and the guide groove 118a. In the given position.

  The positional relationship between the upper protrusion 116e and the guide groove 118a is determined so that the counter 6 does not interfere with the cabinet body 2 when the rotary hook 116 pivots to the release position 116b to release the counter 6 from the folding position 6b. It is done. The position where the counter 6 is released from the folding position 6b is preferably the position where the support frame 4 has moved most downward. As a modification, within such a range, a plurality of guide grooves 118a for guiding to the rear plate 2d side as it goes downward may be provided continuously.

  Further, when the rotary hook 116a is at the release position 116b and the counter 6 is not at the folding position 6b, the rotary shaft 6e is held by the rotary hook 116 because the lower protrusion 116f of the rotary hook 116 is obstructed by the rotary shaft 6e. It is configured not to move to a position.

  Next, the operation and action of the wall cabinet of the fourth embodiment will be described. Hereinafter, only the parts different from the operation and action of the wall cabinet of the first embodiment will be described.

  In a state where the support frame 4 is at the upper position 4a and the counter 6 is held at the folded position 6b by the holding portion 112, the lever portion 32d of the stopper 32 is pivoted from the engagement position 32a to the release position 32b. Thereby, the support frame 4 is allowed to move downward while the counter 6 is held at the folding position 6b by the holding portion 112.

  When the support frame 4 is at the upper position 4a and starts to descend from the position, the rotary hook 116 is urged to the holding position 116a, and the lower protrusion 116f is engaged with the rotary shaft 6e, and thus the counter 6 is held. The portion 112 is held at the folding position 6b. Accordingly, the counter 6 is prevented from rotating from the folding position 6b toward the deployed position 6a, and the counter 6 cannot be rotated from the folded position 6b toward the deployed position 6a.

  When the support frame 4 is lowered while the counter 6 is held at the folding position 6b, the upper protrusion 116e is guided by the guide groove 118a of the guide member 118, and the upper side 116c of the rotary hook 116 moves the rotary hook 116 to the holding position 116a. A force for pivoting the rotary hook 116 to the release position 116b against the biasing force is received, and the rotary hook 116 is pivoted between the release positions 116b. Thereby, the lower protrusion 116f moves away from the rotation shaft 6e. As a result, the rotation shaft 6c of the counter 6 is allowed to rotate, and the counter 6 can be released from the folding position 6b.

  Next, the counter 6 is rotated from the folding position 6b to the unfolding position 6a. Specifically, the counter 6 may be moved by hand, or by adjusting a rotary damper (not shown) or the like attached to the rotating shaft 6e, the counter 6 slowly moves to the deployment position 6a by its own weight. You may comprise so that it may move. Thus, the counter 6 can be used.

  When the counter 6 is moved from the folding position 6b, the lower protrusion 116f and the notch 6h of the rotating shaft 6e are not aligned, and the rotating hook 116 cannot be moved to the holding position 116a. Thereby, the upper protrusion 116e cannot escape from the guide groove 118a, and the support frame 4 is prevented from rising.

  When the support frame 4 and the counter 6 are stored in the rear storage portion 12b, the counter 6 is rotated from the deployed position 6a to the folding position 6b. Thereby, the notch 6h of the rotating shaft 6e and the lower protruding portion 116f are aligned, and the rotating hook 116 can be moved to the holding position 116a. When the support frame 4 is lifted, the upper protrusion 116e is guided in the guide groove 118a of the guide member 118, and the rotary hook 116 is biased to the holding position 116a by a spring (not shown), and the counter 6 is folded into the folding position 6b. Hold on.

  Next, when the support frame 4 is lifted while the counter 6 is held at the folding position 6b by the holding portion 112, the hook portion 32c of the stopper 32 is engaged with the notch 34b, and the support frame 4 is moved to the upper position 4a. Maintained. During this time, the rotary hook 116 is urged to the holding position 116a by a spring (not shown), and has the same effect as when the counter 6 is lowered.

  In the above-described wall cabinet 110, since the holding portion 112 is attached to the support frame 4, the counter 6 can be stored and lowered together with the support frame 4 while being held at the folding position 6b by the holding portion 112. Thus, interference between the counter 6 and the cabinet body 2 can be prevented, and the counter 6 and the support frame 4 can be stored and lowered smoothly.

  Further, while the support frame 4 moves downward to the vertical position immediately before the upper protrusion 116e is received in the guide groove 118a, at least the holding portion 112 holds the counter 6 and extends from the folding position 6b. It prevents that it rotates toward 6a, and thereby prevents that the counter 6 and the cabinet main body 2 which rotate toward the deployment position 6a from the folding position 6b interfere. Further, when the counter 6 is not in the folding position 6b, the support frame 4 is prevented from being raised. That is, the counter does not expand unless it is lowered to a predetermined position, and the support frame does not rise unless the counter is folded.

  Moreover, since the counter 6 cannot be moved upward when the counter 6 is not in the folding position 6b, it is possible to prevent the support frame 4 from being moved excessively when an object is placed on the counter 6. . Further, when the counter 6 is deployed, the rotary hook 116 cannot be pivoted to the holding position 116a, and thus the rotary hook 116 and the support frame 4 cannot be lifted. Therefore, it is possible to prevent the counter 6 from shaking up and down during deployment.

  Further, the rotation hook 116 is alternately positioned between the holding position 116a and the release position 116b so as to prevent the support frame 4 from moving upward at a plurality of vertical positions. Alternatively, the guide groove 118a may be formed. In that case, the counter 6 can be used at a plurality of height positions in the vertical direction.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims. Needless to say, these are also included within the scope of the present invention.

  The combination of the holding portion of the slide frame 16 and the protruding portion of the counter 6 may be in any other form as long as the counter 6 can be held at the folding position 6b.

  In the first embodiment, the holding portion 52 engages with the holding protrusion 31 of the counter 6, and in the second embodiment, the holding portion 72 engages with the pin 28 c of the diagonal support link 28, and the third In the embodiment, the holding portion 92 is engaged with the hole 6g of the counter 6, and in the fourth embodiment, the holding portion 116 is engaged with the rotating shaft 6e of the counter 6, but these combinations are mutually connected. It may be exchanged.
