The biasing member 54 is a coil spring. The biasing member 54 has one end connected to the side surface portion 50 of the opening/closing mechanism, and the other end connected to the arm body 531 of the arm portion 53. The biasing member 54 is connected to the bottom side of the substantially triangular shape of the arm main body 531 near the substantially central portion of the arm main body 531 in the longitudinal direction. The biasing member 54 is connected to the arm portion 53 in a state close to the side surface portion 50 of the opening/closing mechanism, and when the door 10 is opened, the biasing member 54 urges the door 10 toward the inside of the storage space 9 via the arm portion 53. to strengthen

The damping member 55 is, for example, a gas spring type damper. The damping member 55 is connected at one end to the opening/closing mechanism side surface portion 50 of the side member 3 and at the other end to the arm body 531 of the arm portion 53 at a position substantially parallel to the biasing member 54 . The damping member 55 is connected to the top side of the approximately triangular shape of the arm body 531 near the approximately central portion of the arm body 531 in the longitudinal direction. 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 disposed so as to be movable along the longitudinal direction of the cylinder, and is configured such that the movement of the rod 552 is slowed by the gas. The damping member 55 damps the force of opening and closing the door 10 and suppresses the impact when the door 10 is opened and closed.

The opening/closing movement of the door 10 will be described with reference to FIGS. 4A, 4B, and 6. As shown in FIG. 4A, when the door 10 is closed, the roller 522 of the roller section 52 is located at the closest end of the guide rail 51. The arm main body 531 of the arm portion 53 extends downward from the side member 3. The user places his/her 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 located further back than the front upper frame 21, the user can easily reach the lower end of the door 10.

FIG. 6 is a side view showing the locus of rotation of the door 10. When the lower end of the door 10 is pushed up, the arm main body 531 connected to the door 10 rotates upward around a rotation shaft 531a connected to the side member 3. During 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 the distal end of the arm body 531 moves away from the user as the arm body 531 rotates. . Simultaneously with the biasing of the biasing member 54, a damping member 55 attenuates the biasing force of the biasing member 54 so that the biasing force does not become too strong.

When the door 10 rotates around one end of the arm body 531, the other end of the arm body 531 is connected to the lower part of the door 10, so as the lower part of the door 10 rotates, the upper part of the door 10 moves into the storage space 9. Move to the back of the At the same time, the roller 522 connected to the top of the door 10 rolls toward the back within the guide rail 51, so the door 10 moves smoothly. Finally, the upper end of the door 10 moves to the innermost end of the guide rail 51. Then, as shown in FIG. 4B, the door 10 extends in a substantially horizontal direction, and is arranged so as to overlap the upper surface 51b of the guide rail 51 when the door 10 is fully open. As shown in FIG. 6, while the door 10 is rotating, the upper end of the door 10 protrudes beyond the surface of the door 10 overlapping the guide rail 51 in the fully open state. However, the storage shelf 1 does not have a top plate 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. The front upper frame 21 and the rear upper frame 22 are disposed above the door 10, which overlaps the upper surface 51b of the guide rail 51, in a fully open state. Therefore, even if the upper end protrudes due to the movement of the door 10, it will not interfere with furniture placed above the storage shelf 1, such as the bottom surface of the hanging cabinet 300, etc. If the top surface 210, bottom surface 220, and back surface 230 of the storage space are open without providing a plate or the like, the storage shelf 1 becomes lightweight and easy to install. Since the upper surface 310 is open, there is no need to design the upper end of the storage shelf 1 to be high in consideration of the locus of movement of the upper end of the door 10 when moving the door 10 to the open state.

According to this embodiment, the following effects are achieved. The storage shelf 1 is arranged in an opening 90 on the front side of a storage space 9 for storing articles, and includes a door 10 that opens and closes the opening 90, and a pair of side members 3 arranged on the sides 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 arranged on the back surface of the door 10 and capable of rolling within the guide rail 51, and a pair of rollers 522 at one end. An arm portion 53 is rotatably connected to the side member 3 of the door 10 and the other end is connected to the back surface of the door 10. The structure includes a biasing member 54 that biases. When the door 10 is pushed upward from below while rotating the arm part 53, the roller 522 arranged on the back surface of the door 10 slides within the guide rail 51 and moves to the back side. Therefore, the door can be easily opened and closed by a single action of pushing up or pushing down the door 10. When opening the door 10, the door 10 moves to the back of the storage space 9 along the guide rail 51 provided on the side member 3, so that the door 10 does not protrude to the outside of the storage shelf 1. do not have. Therefore, even if the hanging cabinet 300, other furniture, lighting, etc. are arranged above, the door 10 and other furniture do not interfere with each other, and the door 10 can be installed in a compact space.

According to this embodiment, the structure further includes a damping member 55 connected to the arm portion 53 and damping the force of opening and closing the door 10 . This allows the door 10 to open and close quietly and smoothly.

According to this embodiment, the guide rail 51 is arranged at the upper part of the storage space 9, the roller 522 is connected to the upper end side of the door 10, and when the door 10 is fully opened, the door 10 is placed on the upper surface 51b of the guide rail 51. They were placed so that they overlapped. Thereby, the door 10 can be most compactly accommodated within the storage space 9 when the door 10 is opened. Therefore, the storage space 9 can be made larger. At the same time, the door 10 does not protrude above the storage shelf 1 when the door 10 is opened. Therefore, the door 10 does not interfere with surrounding furniture, and the degree of freedom in installing the storage shelf 1 is increased.

According to the present embodiment, the frame member 2 is substantially L-shaped in cross section and has a hanging portion 211 that hangs down from the upper end of the storage space 9 toward the front side, and a top surface portion 212 that extends in a substantially horizontal direction from the upper end of the hanging portion 211. It is composed of: The front upper frame 21 and the rear upper frame 22 of the frame material 2 are arranged above the door 10 overlapping the upper surface 51b of the guide rail 51 when the door 10 is fully opened. 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 is between the guide rail 51 and the top surfaces 212 and 222 of the front upper frame 21 and the rear upper frame 22. move through the gap. Therefore, the upper end of the storage shelf 1 can be placed as low as possible without interfering with the movement trajectory of the door 10, and the storage shelf 1 can be formed compactly.

The present disclosure is not limited to the above-described embodiments, and any modifications, improvements, etc. that can achieve the objectives of the present disclosure are included in the present disclosure.

The bent piece 263 is a surface that bends and extends from the lower end of the hanging portion 261 toward the central portion in the depth direction. The upper frame 26 is formed by bending a steel plate. Even with such a configuration, if the upper end of the door 10 can be placed in a position that does not interfere with the rotating locus, the door 10 can be placed inside the storage space 9, and the structure outside the storage shelf 1 can be placed inside the storage space 9. It becomes possible to arrange the storage shelf 1 regardless of the arrangement. In addition, the storage space 9 can be made larger when the door 10 is closed.

In the above embodiment, the opening/closing mechanism side part 50 is described as a plate-shaped member fixed to the main side plate 31 of the side member 3. However, other constituent members of the opening/closing mechanism 5 may be directly fixed to the main side plate 31 without having the opening/closing mechanism side part 50.

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 members only need to be able to connect the frame members 2 or provide the guide rails 51. For example, a long profile similar to the frame material or a lattice-like net may be provided as the side member.

Furthermore, the shapes and arrangement of the arm portion 53, the biasing member 54, and the damping member 55 are not limited to the configurations described in the above embodiments. 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 approximately central portion of the arm body 531 in the longitudinal direction. Further, the shape of the arm body 531 may also be other shapes such as a rectangle or a parallelogram.

Furthermore, although the biasing member 54 and the damping member 55 have been described using a coil spring and a gas spring damper as examples, they are not limited thereto. The biasing member may have any other configuration as long as it can bias the arm toward the storage space, and the damper may have other configurations as long as it can attenuate the force of opening and closing the door.

In the above embodiment, the front upper frame 21 and the rear upper frame 22 have been described as having a substantially L-shape in cross section. However, the cross-sectional shapes of the front upper frame 21 and the rear upper frame 22 are not limited to the L-shape. It may have a rectangular hollow structure, or it may have any shape such as a substantially triangular shape.
