In the present invention and this embodiment, the front side facing the wall W is defined as "front", the back side as "rear", the left side as "left", and the right side as "right".

The wall storage device A has a known structure, and although not shown, includes a plurality of partition plates extending in the vertical direction on the surface of the wall W, and a plurality of upper and lower shelves, top plates and bottom plates extending in the horizontal left and right directions. are intersected and connected, and the space partitioned by them is used as a storage space.

The wall surface storage unit U according to Embodiment 1 of the present invention is partially incorporated in the wall surface storage device A. The wall storage unit U is, for example, formed into a vertically elongated thin unit with a width of 740 mm, a height of 1975 to 2025 mm, and a depth of 150 mm, and its lower end is incorporated in contact with the floor F ( 3 to 6). As a result, the wall storage device A into which the wall storage unit U is incorporated is also thin.

As shown in FIGS. 1 to 7, the wall surface storage unit U has a rectangular box-shaped storage body 1 that opens forward. More specifically, the storage main body 1 includes, for example, a rectangular back plate 2 positioned on the rear side (wall W side), and upper and lower sides connected to the left and right sides of the front surface of the back plate 2 so as to face each other. left and right side plates 3, 3 extending in a direction, a top plate 4 connected between upper end portions of both side plates 3, 3, and a bottom plate 5 connected between lower end portions of both side plates 3, 3, and these are assembled into a rectangular box. In the structure in which the wall surface storage unit U is incorporated in the wall surface storage device A, the left and right side plates 3, 3 of the storage main body 1 constitute the partition plates of the wall surface storage device A, and the top plate 4 of the wall surface storage device A. The shelf plate and the bottom plate 5 constitute the bottom plate of the wall storage device A, respectively. The back plate 2 may be shared with the back plate of the wall storage device A.

In the storage body 1 of the wall surface storage unit U, for example, six upper and lower shelf boards 7, 7, 8, 8, 11, and 12 extending in the left-right horizontal direction are arranged. Two lower shelf plates 7 and 7 are arranged at positions near the bottom plate 5 and near the lower end in the storage body 1, and two upper shelf plates 8 and 8 are arranged at positions near the top plate 4 and near the upper end. These shelf boards 7, 7, 8, 8 are either fixed to the left and right side boards 3, 3, or supported by a connection structure using dowels so that the height position can be changed.

In the storage body 1, a first shelf board 11 is arranged slightly below the center of the vertical height, and a second shelf board 12 is arranged above the first shelf board 11. - 特許庁ing. As shown in FIG. 6, the height h1 of the upper surface of the first shelf board 11 from the upper surface of the floor F is, for example, h1=720.5 mm, and the same height h2 of the upper surface of the second shelf board 12 is, for example, h2=1098 mm. .5 mm.

The first and second shelf plates 11 and 12 are fixed to the storage main body 1 in a state in which each part (rear part) is arranged inside the storage main body 1 . That is, both of these shelf boards 11 and 12 are of the folding type, and have a fixing portion 15 arranged and fixed in the storage body 1 and a horizontal axis extending in the left-right direction at the front end portion of the fixing portion 15. and a movable portion 16 rotatably supported at its base end (rear end in horizontal position, lower end in vertical position). Note that the fixed part 15 and the movable part 16 will be described with the same reference numerals as in the shelf boards 11 and 12 .

The movable parts 16 , 16 of the first and second shelf boards 11 , 12 protrude forward from the storage body 1 so that the upper surface is flush with the fixed part 15 and extend from the front end of the fixed part 15 . It is rotatable within an angular range of 90° between a vertical position (upright position) extending vertically upward.

As shown in FIG. 8, each movable portion 16 of the first and second shelf plates 11 and 12 is attached to the fixed portion 15 between the upper surface of the front end portion of the fixed portion 15 and the base end portion of the movable portion 16. Further, for example, a plurality of left and right hinges 18, 18, . In addition, positions near the base ends of the left and right edges of the movable portion 16 (rear end in the horizontal position, lower end in the vertical position) and positions higher than the fixed portion 15 on the inner surfaces of the left and right side plates 3, 3 (mounting plate 6, which will be described later) ) are connected to down stays 19, 19 (only the right side is shown in FIG. 8) that can be bent. The down stays 19, 19 develop from a V-shaped bent state to an I-shaped state as the movable portion 16 rotates from the vertical position to the horizontal position, and the expanded state (I-shaped state) is maintained. As a result, the movable portion 16 is fixed at the horizontal position. When the movable portion 16 is in the horizontal position, the movable portion 16 and the fixed portion 15 are continuous in the form of a single plate with their upper surfaces being flush with each other. On the other hand, when the movable portion 16 rotates from the horizontal position to the vertical position, the down stays 19, 19 bend and return to the original V shape.

By the way, as shown in FIG. 7, the lateral width L1 (for example, 709.5 mm) of the fixing portion 15 of the first and second shelf plates 11 and 12 is set so that the side plates 3 and 3 of the storage body 1 are fitted. slightly less than the spacing of the 3,3 inner surfaces (eg 710 mm). Further, the lateral width L2 (for example, 670 mm) of the movable portion 16 of the first and second shelf plates 11 and 12 is even smaller than the lateral width L1 of the fixed portion 15 of the first and second shelf plates 11 and 12 . Therefore, the downstays 19, 19 are attached to a mounting plate 6 having a predetermined thickness and fixed to the inner surface of the side plate 3. As shown in FIG.

The depth of the fixing portion 15 of the first and second shelf plates 11 and 12 is slightly smaller than the depth of the side plates 3 and 3 of the storage body 1 . The front end surface of the fixed portion 15 is recessed rearward from the front end surfaces of the side plates 3, 3, and a space is generated on the front side of the front end surface (see FIGS. 5 and 6). As shown in FIG. 7, the movable portions 16 of the first and second shelf plates 11 and 12, which are positioned outside the storage body 1 in the horizontal position except for the base ends, are positioned in the vertical position as shown in FIG. Then, between the left and right side plates 3, 3 of the storage main body 1, the rear facing surface (upper surface when in the horizontal position) abuts or approaches the front end surface of the fixing portion 15, and is in the space on the front side of the fixing portion 15. It's settled.

A stopper member having a similar structure may be provided for the second shelf board 12 as well.

As shown in FIG. 6, the depth d1 in the front-rear direction of the movable portion 16 of the first shelf 11 is, for example, d1=350 mm, which is greater than the same depth d2 (for example, 190 mm) of the movable portion 16 of the second shelf 12. big. As shown in FIG. 5, the depth d1 in the front-rear direction of the movable portion 16 of the first shelf 11 is smaller than the height h3 between the first and second shelves 11 and 12 (d1>h3). The depth d2 in the front-rear direction of the movable portion 16 of the second shelf 12 is smaller than the height h4 between the second shelf 12 and the upper shelf 8 thereon (d2>h4). Due to this dimensional relationship, the movable parts 16, 16 of the shelves 11, 12 are arranged at the front end part in the storage body 1 in the vertical position, and as shown in FIGS. When 26 is in the open position, it becomes an inner door that closes the opening of the storage main body 1 at the upper and lower intermediate portions.

In addition, the wall surface storage apparatus A may be constructed as a part of the wall W. In the present invention and this embodiment, the front side facing the wall W is defined as "front", the back side as "rear", the left side as "left", and the right side as "right".

The wall storage device A has a known structure, and although not shown, includes a plurality of partition plates extending in the vertical direction on the surface of the wall W, and a plurality of upper and lower shelves, top plates and bottom plates extending in the horizontal left and right directions. are intersected and connected, and the space partitioned by them is used as a storage space.

The wall surface storage unit U according to Embodiment 1 of the present invention is partially incorporated in the wall surface storage device A. The wall storage unit U is, for example, formed into a vertically elongated thin unit with a width of 740 mm, a height of 1975 to 2025 mm, and a depth of 150 mm, and its lower end is incorporated in contact with the floor F ( 3 to 6). As a result, the wall storage device A into which the wall storage unit U is incorporated is also thin.

As shown in FIGS. 1 to 7, the wall surface storage unit U has a rectangular box-shaped storage body 1 that opens forward. More specifically, the storage main body 1 includes, for example, a rectangular back plate 2 positioned on the rear side (wall W side), and upper and lower sides connected to the left and right sides of the front surface of the back plate 2 so as to face each other. left and right side plates 3, 3 extending in a direction, a top plate 4 connected between upper end portions of both side plates 3, 3, and a bottom plate 5 connected between lower end portions of both side plates 3, 3, and these are assembled into a rectangular box. In the structure in which the wall surface storage unit U is incorporated in the wall surface storage device A, the left and right side plates 3, 3 of the storage main body 1 constitute the partition plates of the wall surface storage device A, and the top plate 4 of the wall surface storage device A. The shelf plate and the bottom plate 5 constitute the bottom plate of the wall storage device A, respectively. The back plate 2 may be shared with the back plate of the wall storage device A.

In the storage body 1 of the wall surface storage unit U, for example, six upper and lower shelf boards 7, 7, 8, 8, 11, and 12 extending in the left-right horizontal direction are arranged. Two lower shelf plates 7 and 7 are arranged at positions near the bottom plate 5 and near the lower end in the storage body 1, and two upper shelf plates 8 and 8 are arranged at positions near the top plate 4 and near the upper end. These shelf boards 7, 7, 8, 8 are either fixed to the left and right side boards 3, 3, or supported by a connection structure using dowels so that the height position can be changed.

In the storage body 1, a first shelf board 11 is arranged slightly below the center of the vertical height, and a second shelf board 12 is arranged above the first shelf board 11. - 特許庁ing. As shown in FIG. 6, the height h1 of the upper surface of the first shelf board 11 from the upper surface of the floor F is, for example, h1=720.5 mm, and the same height h2 of the upper surface of the second shelf board 12 is, for example, h2=1098 mm. .5 mm.

The first and second shelf plates 11 and 12 are fixed to the storage main body 1 in a state in which each part (rear part) is arranged inside the storage main body 1 . That is, both of these shelf boards 11 and 12 are of the folding type, and have a fixing portion 15 arranged and fixed in the storage body 1 and a horizontal axis extending in the left-right direction at the front end portion of the fixing portion 15. and a movable portion 16 rotatably supported at its base end (rear end in horizontal position, lower end in vertical position). Note that the fixed part 15 and the movable part 16 will be described with the same reference numerals as in the shelf boards 11 and 12 .

The movable parts 16 , 16 of the first and second shelf boards 11 , 12 protrude forward from the storage body 1 so that the upper surface is flush with the fixed part 15 and extend from the front end of the fixed part 15 . It is rotatable within an angular range of 90° between a vertical position (upright position) extending vertically upward.

As shown in FIG. 8, each movable portion 16 of the first and second shelf plates 11 and 12 is attached to the fixed portion 15 between the upper surface of the front end portion of the fixed portion 15 and the base end portion of the movable portion 16. Further, for example, a plurality of left and right hinges 18, 18, . In addition, positions near the base ends of the left and right edges of the movable portion 16 (rear end in the horizontal position, lower end in the vertical position) and positions higher than the fixed portion 15 on the inner surfaces of the left and right side plates 3, 3 (mounting plate 6, which will be described later) ) are connected to down stays 19, 19 (only the right side is shown in FIG. 8) that can be bent. The down stays 19, 19 develop from a V-shaped bent state to an I-shaped state as the movable portion 16 rotates from the vertical position to the horizontal position, and the expanded state (I-shaped state) is maintained. As a result, the movable portion 16 is fixed at the horizontal position. When the movable portion 16 is in the horizontal position, the movable portion 16 and the fixed portion 15 are continuous in the form of a single plate with their upper surfaces being flush with each other. On the other hand, when the movable portion 16 rotates from the horizontal position to the vertical position, the down stays 19, 19 bend and return to the original V shape.

By the way, as shown in FIG. 7, the lateral width L1 (for example, 709.5 mm) of the fixing portion 15 of the first and second shelf plates 11 and 12 is set so that the side plates 3 and 3 of the storage body 1 are fitted. slightly less than the spacing of the 3,3 inner surfaces (eg 710 mm). Further, the lateral width L2 (for example, 670 mm) of the movable portion 16 of the first and second shelf plates 11 and 12 is even smaller than the lateral width L1 of the fixed portion 15 of the first and second shelf plates 11 and 12 . Therefore, the downstays 19, 19 are attached to a mounting plate 6 having a predetermined thickness and fixed to the inner surface of the side plate 3. As shown in FIG.

The depth of the fixing portion 15 of the first and second shelf plates 11 and 12 is slightly smaller than the depth of the side plates 3 and 3 of the storage body 1 . The front end surface of the fixed portion 15 is recessed rearward from the front end surfaces of the side plates 3, 3, and a space is generated on the front side of the front end surface (see FIGS. 5 and 6). As shown in FIG. 7, the movable portions 16 of the first and second shelf plates 11 and 12, which are positioned outside the storage body 1 in the horizontal position except for the base ends, are positioned in the vertical position as shown in FIG. Then, between the left and right side plates 3, 3 of the storage main body 1, the rear facing surface (upper surface when in the horizontal position) abuts or approaches the front end surface of the fixing portion 15, and is in the space on the front side of the fixing portion 15. It's settled.

A stopper member having a similar structure may be provided for the second shelf board 12 as well.

As shown in FIG. 6, the depth d1 in the front-rear direction of the movable portion 16 of the first shelf 11 is, for example, d1=350 mm, which is greater than the same depth d2 (for example, 190 mm) of the movable portion 16 of the second shelf 12. big. As shown in FIG. 5, the depth d1 in the front-rear direction of the movable portion 16 of the first shelf 11 is smaller than the height h3 between the first and second shelves 11 and 12 (d1>h3). The depth d2 in the front-rear direction of the movable portion 16 of the second shelf 12 is smaller than the height h4 between the second shelf 12 and the upper shelf 8 thereon (d2>h4). Due to this dimensional relationship, the movable parts 16, 16 of the shelves 11, 12 are arranged at the front end part in the storage body 1 in the vertical position, and as shown in FIGS. When 26 is in the open position, it becomes an inner door that closes the opening of the storage body 1 at the upper and lower intermediate portions.
