[Figure 7] This figure shows the trajectory of the door of a storage cabinet when it is opened and closed in another embodiment. [Modes for carrying out the invention]

[0007] Embodiments of this disclosure will be described in detail below with reference to the drawings. In this specification, the left-right direction refers to the left and right when the storage shelf 1 is viewed from the front. The front side refers to the side facing the user, and the back side refers to the back side. The depth direction is the direction connecting the front and the back. As shown in Figure 1, the storage shelf 1 of this embodiment 1 is placed under a kitchen wall cabinet 300 and is fixed to the wall surface on which the wall cabinet 300 is installed. Figure 1 shows the storage shelf 1 with the door 10 open. The storage shelf 1 has a storage space 9 for storing items inside, and includes a door 10, a frame material 2, a side member 3, a bottom member 41, a hanging member 42, and an opening and closing mechanism 5 for the door 10.

[0008] Frame material 2 is a long member that extends in the left-right direction when viewed from the front of the storage shelf 1. Frame material 2 is a molded material made by extruding a metal such as aluminum. Frame material 2 is positioned at the upper and lower front and upper and lower rear ends. As shown in Figure 2, frame material 2 has a front upper frame 21, a rear upper frame 22, a front lower frame 23, a rear lower frame 24, and a hanger frame 25.

[0009] As shown in Figures 2 and 3, the storage space 9 is formed in the inner space enclosed by the frame material 2. The top surface 210, bottom surface 220, and back surface 230 of the storage space 9 are open. The opening 90 is formed between the front upper frame 21 and the front lower frame 23.

[0010] The front upper frame 21 extends to the upper front of the storage space 9. The rear upper frame 22 extends to the upper rear of the storage space 9. As shown in Figure 4A, the front upper frame 21 and the rear upper frame 22 have a roughly L-shaped cross-section, and each has a hanging portion 211, 221 and a top portion 212, 222. The hanging portions 211, 221 are surfaces that hang down from the upper end of the storage space 9 on the front and back sides of the storage shelf 1, and constitute the shorter side of the L-shape. The top portions 212, 222 are surfaces that extend roughly horizontally from the upper ends of the hanging portions 211, 221, and constitute the longer side of the L-shape.

[0011] The front lower frame 23 is positioned at the lower front of the storage space 9. The rear lower frame 24 is positioned at the lower rear of the storage space 9. As shown in Figures 4A and 4B, the front lower frame 23 and the rear lower frame 24 are each configured in a hollow shape in cross-section and have locking projections 231 and 241, respectively. The locking projections 231 and 241 extend from the sides of the front lower frame 23 and the rear lower frame 24 facing the interior of the storage space 9 toward the interior of the storage space 9. The locking projections 231 and 241 are formed to extend from one end to the other in the longitudinal direction of the front lower frame 23 and the rear lower frame 24, respectively. The locking projections 231 and 241 are projections for locking the bottom surface member 41, which will be described later. As shown in Figure 2, the distance between the outer surfaces of the front lower frame 23 and the rear lower frame 24 relative to the storage space 9 is shorter than the distance between the hanging portions 211 and 221 of the front upper frame 21 and the rear upper frame 22. The front upper frame 21, the rear upper frame 22, the front lower frame 23, and the rear lower frame 24 define the four corners of the storage shelf in a side view.

[0012] The bottom surface 220 is open between the front lower frame 23 and the rear lower frame 24, allowing long utensils such as ladles to be stored with their ends extending below the storage shelf 1. Therefore, the height dimension of the storage shelf 1 can be made more compact. The back surface 230 is open between the rear upper frame 22 and the rear lower frame 24, making it possible to install the storage shelf 1 even if, for example, there is a window on the kitchen wall.

[0013] The hanger frame 25 is a frame for suspending the hanging member 42, which will be described later. The hanger frame 25 is positioned below the rear upper frame 22. The hanger frame 25 is a long profile with a hollow cross-section.

[0014] The side member 3 is a plate-shaped member that connects the longitudinal ends of the frame material 2. The side member 3 is positioned on the side of the storage space 9 and is arranged in pairs facing one and the other longitudinal end of the storage shelf 1. The side member 3 has a main side panel 31, an auxiliary side panel 32, and an opening / closing mechanism side part 50. The main side panel 31 is made of a single plate, and the opening / closing mechanism 5, which will be described later, is attached to the inner surface of the main side panel 31. The front upper frame 21 and the rear upper frame 22 are fixed to the upper inner surface of the main side panel 31. The auxiliary side panel 32 is a plate with a smaller area than the main side panel 31 and is connected to the lower end of the main side panel 31 with screws. The auxiliary side panel 32 is a strip-shaped plate that is positioned so that its longitudinal direction extends along the depth direction of the storage shelf 1. The front lower frame 23 and the rear lower frame 24 are fixed to the front and rear ends of the auxiliary side plate 32. The opening / closing mechanism side portion 50 is a roughly rectangular plate with a smaller area than the main side plate 31, and is provided on the opening / closing mechanism 5, which will be described later. The opening / closing mechanism side portion 50 is fixed in contact with the pair of main side plates 31.

[0015] The bottom surface member 41 is various plate-like members detachably arranged between the front lower frame 23 and the rear lower frame 24. The bottom surface member 41 is formed such that the dimension in the depth direction is spanned between the front lower frame 23 and the rear lower frame 24 and is placed on the locking protrusions 231 and 241. As shown in FIGS. 2 and 3, the bottom surface member 41 includes, for example, a shelf board 411 for pot lids, a shelf board 412 for seasonings, and a draining shelf board 413.

[0016] The shelf board 411 for pot lids is formed with a through groove 411a through which the lower end of the pot lid can be inserted and arranged below the lower end of the shelf board 411 for pot lids so that pot lids of different sizes can be stood upright after washing. As shown in FIG. 3, the lower end of the pot lid is inserted through the through groove 411a, and the lower end of the pot lid is located below the lower ends of the front lower frame 23 and the rear lower frame 24.

[0017] The shelf board 412 for seasonings is a board for placing small bottles and the like, and has a raised surface 412b for preventing falling at the periphery.

[0018] The draining shelf board 413 is a shelf board on which washed items such as bowls can be temporarily placed, and has a front bottom surface 4131 and a rear bottom surface 4132. The front bottom surface 4131 is the bottom surface located on the front side when the draining shelf board 413 is in use, and the rear bottom surface 4132 is the bottom surface located on the rear side during use and is located below the front bottom surface 4131. A step 4133 is formed between the front bottom surface 4131 and the rear bottom surface 4132. The lower end of the draining shelf board 413 is located below the lower ends of the front lower frame 23 and the rear lower frame 24 so that items with a relatively large vertical dimension when placed upright, such as cutting boards and large plates, can also be placed.

[0019] As shown in FIGS. 3 to 4B, the pot lid shelf board 411 and the seasoning shelf board 412 have a narrow locking edge 414 that can be locked onto the locking protrusions 231 and 241 on the edges along the longitudinal direction of the front lower frame 23 and the rear lower frame 24. The locking edge 414 is formed in a substantially U-shaped cross-section that opens downward. The draining shelf board 413 has stepped surfaces 4132a and 4133a that can be arranged on the locking protrusions 231 and 241 at the front end of the front bottom surface 4131 and the rear end of the rear bottom surface 4132, respectively, and is thus locked to the locking protrusions 231 and 241. The pot lid shelf board 411, the seasoning shelf board 412, and the draining shelf board 413 are examples, and the detailed configuration, arrangement, dimensions, etc. of the bottom member 41 may be changed as appropriate.

[0020] The hanging member 42 is a member that is locked to the hanger frame 25 and can hang and store various items. The hanging member 42 extends along the longitudinal direction of the hanger frame 25 and has a substantially U-shaped locking portion 420 that opens downward at the upper end side. The locking portion 420 has a bottom surface 420a, a rear side surface 420b, and a front side surface 420c. The bottom surface 420a is a plane that extends on the closed side of the U shape and abuts against the upper surface of the hanger frame 25. The rear side surface 420b hangs downward from the rear end of the bottom surface 420a and abuts against the back surface of the hanger frame. The front side surface 420c hangs downward from the front end of the bottom surface 420a, and a member having a shape corresponding to the member to be hung is provided. For example, the hanging member 42 has a ladle hanger 421, a dishcloth hanger 422, and a cutlery shelf 423.

[0021] The ladle hanger 421 has a plurality of hooks 4211 extending from the front side surface 420c of the locking portion 420. The plurality of hooks 4211 are arranged at intervals along the longitudinal direction of the hanger frame 25. It is possible to hang balls, fried foods, spatulas, etc. on the hooks 4211. Since the space between the front lower frame 23 and the rear lower frame 24 is open, even if the length of the ladle exceeds the vertical dimension of the storage shelf 1, the ladle can be held in a state of being hung on the hooks 4211.

[0022] The dishcloth hanger 422 has a frame-shaped hanging section 4221 formed on the front side 420c towards the front. The hanging section 4221 is formed in a vertically elongated frame shape on which dishcloths can be hung. Dishcloths, rubber gloves, etc., can be inserted through vertically elongated through holes formed on the inside of the hanging section 4221 and hung.

[0023] The cutlery rack 423 has support parts 4231 hanging down from both ends in the longitudinal direction of the locking part 420, and a shelf board 4232 extending towards the front from the lower end of the support parts 4231. The shelf board 4232 is suspended midway between the upper rear frame 22 and the lower rear frame 24 in the vertical direction, and is a roughly rectangular tray whose longitudinal direction is aligned with the longitudinal direction of the hanger frame 25. Seasonings and the like can be placed on the shelf board 4232. The ladle hanger 421, dishcloth hanger 422, and cutlery rack 423 are examples, and the detailed configuration, arrangement, dimensions, etc. of the hanging members 42 may be changed as appropriate.

[0024] The door 10 is positioned in the opening 90 on the front side of the storage space 9 and opens and closes the opening 90. The door 10 is made of a plate-like member. The longitudinal dimension of the door 10 corresponds to the distance connecting the inner surfaces of a pair of side members 3, and the door 10 is positioned with a gap between the pair of side members 3 that allows it to move up and down. The short-side dimension of the door 10 corresponds to the distance connecting the lower end to the upper end of the side members 3. The door 10 moves by an opening and closing mechanism 5, which will be described below. As shown in Figure 5, the door 10 is constructed by placing a thin plate on the front surface of a plate-like frame that frames the four sides. In Figure 5, the rear upper frame 22 and the rear lower frame 24 are omitted.

[0025] The opening and closing mechanism 5 opens the door 10 by moving the door 10 from below to above, changing its orientation so that it is aligned with the depth direction from a vertically closed position, and moving it towards the back. To close it, the reverse operation is performed. The opening and closing mechanism 5 includes an opening and closing mechanism side section 50, a guide rail 51, a roller section 52, an arm section 53, a biasing member 54, and a damping member 55.

[0026] The opening / closing mechanism side portion 50 is a pair of plate-shaped members positioned on the side of the storage space 9 and fixed to the inner surface of the main side plate 31 of the side member 3. The opening / closing mechanism side portion 50 extends along the main side plate 31 and constitutes a part of the side member 3. The opening / closing mechanism side portion 50 supports the arm portion 53, biasing member 54, and damping member 55, which are described below.

[0027] The guide rail 51 is positioned along the depth direction of the storage space 9, specifically on the upper part of the side surface of the storage space 9, on the upper inner side of the pair of side members 3. The guide rail 51 is positioned in contact with the upper end of the side surface 50 of the opening and closing mechanism of the side member 3. The guide rail 51 is a long member with a substantially U-shaped recess in cross-section and its longitudinal direction is aligned with the depth direction. The guide rail 51 has a side surface 51a, an upper surface 51b, a lower surface 51c, and a bent piece 51d. The side surface 51a is the lower surface of the closed side of the U-shape and is fixed in contact with the side member 3. The upper surface 51b and the lower surface 51c are a pair of surfaces that rise from both ends of the side surface 51a toward the inside of the storage space 9, with the upper surface 51b extending above the state in which the guide rail 51 is fixed to the side member 3, and the lower surface 51c extending downward. Guide projections for guiding the roller 522 (described later) are formed along the longitudinal direction on the lower surface 51c. The bent piece 51d is formed by bending the free ends of the upper surface 51b and the lower surface 51c so that they move closer together. The roller portion 52 (described later) is rotatably arranged in the recess enclosed by the side surface 51a and the upper and lower surfaces 51c. The inward bending of the bent piece 51d at the free ends of the upper surface 51b and the lower surface 51c holds the roller 522 (described later) so that it does not fall out of the recess.

[0028] The roller section 52 is positioned on the upper part of the back surface of the door 10. The roller section 52 includes a roller support member 521 and a roller 522. As shown in Figure 5, the roller support member 521 has a fixed surface 5211 that is fixed to the back surface of the door 10 by screws, and a support surface 5212 that extends perpendicularly from the fixed surface 5211 in a direction along the side member 3. A shaft portion 5213 that rotatably supports the roller 522 is positioned on the support surface 5212. The roller 522 is a wheel pivotally supported on the shaft portion 5213. The roller 522 engages with a recess in the guide rail 51. The fixed surface 5211 of the roller support member 521 is fixed to the door 10, connecting the roller 522 to the upper end of the door 10. In addition, the roller 522 is positioned on the side surface of the support surface 5212 that faces the side member 3, inserted through the shaft portion 5213. The roller 522 engages with the upper surface 51b and lower surface 51c of the guide rail 51, and its sliding direction is restricted by the bent piece 51d to prevent it from shifting inward into the storage space 9, as it rolls within the guide rail 51. As a result, the roller section 52 can move the upper end of the door 10 back and forth from the front to the back of the storage space 9.

[0029] The arm portion 53 is positioned at the lower part of the back surface of the door 10. The arm portion 53 has an arm body 531 and a connecting portion 532. The arm body 531 is a long, narrow plate-shaped member that connects the door 10 and the side member 3. The arm body 531 has a roughly triangular shape, with one side in the width direction being wider than the other, protruding from the center in the longitudinal direction. One end of the arm body 531 is rotatably connected to the side surface 50 of the opening and closing mechanism of the side member 3. The arm body 531 and the side surface 50 of the opening and closing mechanism are connected by a pivot shaft 531a. The pivot shaft 531a serves as a pivot point that causes the door 10 to rotate and move when the door 10 is opened. The connecting portion 532 is positioned on the back surface of the door and is a member that connects the back surface of the door 10 and the arm body 531. The connecting portion 532 has a fixed surface 5321 that is fixed to the back surface of the door 10 with screws, and a connecting surface 5322 that extends perpendicularly from the fixed surface 5321 in a direction along the side member 3. The other end of the arm body 531 is rotatably connected to the connecting surface 5322.

[0030] The biasing member 54 is a coil spring. One end of the biasing member 54 is connected to the side portion 50 of the opening and closing mechanism, and the other end is connected to the arm body 531 of the arm portion 53. The biasing member 54 is connected to the bottom side of the arm body 531, which is roughly triangular in shape, near the approximate center of the arm body 531 in the longitudinal direction. The biasing member 54 is connected with the arm portion 53 close to the side portion 50 of the opening and closing mechanism, and when the door 10 is opened, it biases the door 10 toward the inside of the storage space 9 via the arm portion 53.

[0031] The damping member 55 is, for example, a gas spring type damper. The damping member 55 is positioned approximately parallel to the biasing member 54, with one end connected to the side portion 50 of the opening and closing mechanism of the side member 3 and the other end connected to the arm body 531 of the arm portion 53. The damping member 55 is connected to the apex side of the arm body 531, which is approximately triangular in shape, near the approximate center of the longitudinal direction of the arm body 531. The damping member 55 has a cylinder 551 and a rod 552. The cylinder 551 is filled with gas and oil. The rod 552 is arranged to move along the longitudinal direction of the cylinder, and the gas is configured to slow the movement of the rod 552. The damping member 55 dampens the force with which the door 10 is opened and closed, and suppresses the impact when the door 10 is opened and closed.

[0032] The opening and closing movement of the door 10 will be explained with reference to Figures 4A, 4B, and 6. As shown in Figure 4A, when the door 10 is closed, the roller 522 of the roller section 52 is located at the frontmost end of the guide rail 51. The arm body 531 of the arm section 53 extends downward from the side member 3. The user places their hand on the lower end of the door 10 and pushes the door 10 upward. At this time, since the front end of the front lower frame 23 is positioned further back than the front upper frame 21, it is easier for the user to place their hand on the lower end of the door 10.

[0033] Figure 6 is a side view showing the rotational trajectory of the door 10. When the lower end of the door 10 is pushed up, the arm body 531 connected to the door 10 rotates upward around the rotation axis 531a connected to the side member 3. During the rotation, the biasing member 54 biases the distal end of the arm body 531 so that it returns to the inside of the storage space 9 even if it moves away from the front side as the arm body 531 rotates. Simultaneously with the biasing by the biasing member 54, the damping member 55 dampens the biasing force so that the biasing force by the biasing member 54 does not become too strong.

[0034] As the door 10 rotates around one end of the arm body 531, the other end of the arm body 531 is connected to the bottom of the door 10. As the bottom of the door 10 rotates, the top of the door 10 moves towards the back of the storage space 9. Simultaneously, the roller 522 connected to the top of the door 10 rolls towards the back within the guide rail 51, causing the door 10 to move smoothly. Finally, the top of the door 10 moves to the furthest end of the guide rail 51. As shown in Figure 4B, the door 10 extends almost horizontally, and in the fully open state, the door 10 is positioned to overlap the upper surface 51b of the guide rail 51. As shown in Figure 6, while the door 10 is rotating, the top of the door 10 protrudes beyond the surface of the door 10 when it is fully open and overlapping the guide rail 51. However, the storage shelf 1 does not have a top panel or the like between the front upper frame 21 and the rear upper frame 22, and the space between the front upper frame 21 and the rear upper frame 22 is open. Furthermore, when fully open, the front upper frame 21 and the rear upper frame 22 are positioned above the door 10 which is superimposed on the upper surface 51b of the guide rail 51. Therefore, even if the upper end of the door 10 protrudes due to its movement, it does not interfere with furniture placed above the storage shelf 1, such as the bottom surface of a hanging cabinet 300. Since the top surface 210, bottom surface 220, and back surface 230 of the storage space are open without any boards or the like, the storage shelf 1 becomes lighter and easier to install. Because the top surface 310 is open, when moving the door 10 to the open position, there is no need to design the top of the storage shelf 1 to be high to account for the trajectory of the upper end of the door 10 as it moves.

[0035] This embodiment provides the following advantages. The storage shelf 1 is configured to include a door 10 that opens and closes the opening 90 and is positioned in the front opening 90 of a storage space 9 for storing items, a pair of side members 3 positioned on the side of the storage space 9, a guide rail 51 provided inside the pair of side members 3 along the depth direction of the storage space 9, a roller 522 positioned on the back of the door 10 and capable of rolling within the guide rail 51, an arm portion 53 with one end rotatably connected to the pair of side members 3 and the other end connected to the back of the door 10, and a biasing member 54 connected to the arm portion 53 and biasing the door 10 toward the inside of the storage space 9 via the arm portion 53. When the door 10 is pushed upward from below while the arm portion 53 is rotated, the roller 522 positioned on the back of the door 10 slides within the guide rail 51 and moves toward the back. Therefore, the door can be easily opened and closed with a single action of pushing the door 10 up or down. Furthermore, when the door 10 is opened, it moves towards the back of the storage space 9 along the guide rail 51 provided on the side member 3, so the door 10 does not protrude outside the storage shelf 1. Therefore, even if overhead cabinets 300, other furniture, lighting fixtures, etc. are placed above, the door 10 will not interfere with other furniture, and it can be installed in a compact space.

[0036] According to this embodiment, the system is further configured to include a damping member 55 connected to the arm portion 53, which reduces the force with which the door 10 is opened and closed. This makes the opening and closing of the door 10 quieter and smoother.

[0037] In this embodiment, the guide rail 51 is positioned at the top of the storage space 9, the roller 522 is connected to the upper end of the door 10, and the door 10 is positioned so that when it is fully open, it overlaps the upper surface 51b of the guide rail 51. As a result, when the door 10 is open, it fits most compactly into the storage space 9. Therefore, the storage space 9 can be made larger. At the same time, when the door 10 is open, it does not protrude above the top of the storage shelf 1. Therefore, the door 10 does not interfere with surrounding furniture, and the degree of freedom in the installation location of the storage shelf 1 is increased.

[0038] According to this embodiment, the storage shelf 2 is constructed with a frame material 2 that is roughly L-shaped in cross-section, having a hanging portion 211 that hangs down from the upper end of the storage space 9 toward the front, and a top surface portion 212 that extends substantially horizontally from the upper end of the hanging portion 211. The front upper frame 21 and the rear upper frame 22 of the frame material 2 are positioned above the door 10, which overlaps with the upper surface 51b of the guide rail 51 when the door 10 is fully open. When the door 10 rotates to open, the upper end of the door 10 that protrudes upward from the upper surface 51b of the guide rail 51 moves in the gap between the guide rail 51 and the top surfaces 212 and 222 of the front upper frame 21 and the rear upper frame 22. As a result, the upper end of the storage shelf 1 can be positioned as low as possible without interfering with the movement trajectory of the door 10, making it possible to form the storage shelf 1 compactly.

[0039] This disclosure is not limited to the embodiments described above, and any modifications, improvements, etc., that can achieve the objectives of this disclosure are included. As shown in Figure 7, in the storage shelf 1A according to another embodiment, the frame material 2 has a top frame 26 instead of the front upper frame 21 and the rear upper frame 22. The top frame 26 has a top surface portion 262, a hanging portion 261, and a bent piece 263. In the storage shelf 1A, the top surface 210 of the storage space 9 is not open. The top surface portion 262 is a flat surface that extends from the front to the back across the top surface 210 of the storage space 9. The hanging portion 261 is a surface that hangs down from the front and rear ends of the top surface portion 262. The bent piece 263 is a surface that bends and extends from the lower end of the hanging portion 261 toward the center in the depth direction. The top frame 26 is formed by bending a steel plate. Even with this configuration, if the upper end of the door 10 can be positioned so as not to interfere with the rotational trajectory, the door 10 can be placed inside the storage space 9, making it possible to place the storage shelf 1 regardless of the arrangement of external structures around the storage shelf 1. In addition, the storage space 9 can be made larger when the door 10 is closed.

[0040] In the above embodiment, the opening / closing mechanism side portion 50 is described as a plate-shaped member fixed to the main side plate 31 of the side member 3. However, the opening / closing mechanism 5 may be configured without the opening / closing mechanism side portion 50, with other components of the opening / closing mechanism 5 being directly fixed to the main side plate 31.

[0041] In the above embodiment, the side member 3 has a plate-shaped main side plate 31. However, the configuration of the side member 3 is not limited to this. The side member can connect the frame material 2 or be provided with guide rails 51. For example, the side member may be a long, shaped material similar to the frame material, or a grid-like mesh.

[0042] Furthermore, the shape and arrangement of the arm portion 53, the biasing member 54, and the damping member 55 are not limited to the configuration described in the above embodiment. The position where the biasing member 54 and the damping member 55 are connected to the arm body 531 is not limited to the vicinity of the approximate center in the longitudinal direction of the arm body 531. Also, the shape of the arm body 531 may be other shapes, such as a rectangle or a parallelogram.

[0043] Furthermore, although the biasing member 54 and the damping member 55 were described using a coil spring and a gas spring type damper as examples, respectively, they are not limited to these. The biasing member only needs to be able to bias the arm portion toward the storage space, and the damper may have other configurations as long as it can dampen the force of opening and closing the door.

[0044] In the above embodiment, the front upper frame 21 and the rear upper frame 22 were described as having a roughly L-shape in cross-section. However, the cross-sectional shape of the front upper frame 21 and the rear upper frame 22 is not limited to an L-shape. They may be rectangular with a hollow structure, roughly triangular, or any other shape. [Explanation of Symbols]
