Summary of the Invention

Problems to be Solved by the Invention

[0004] Since the member that supports the shelf board disclosed in Patent Document 1 has a configuration that protrudes in front of the exterior panel, there is a problem of impairing the design property. Further, since it is a structure in which the shelf board is inserted into the groove portion, it is necessary to provide a play between the groove portion and the shelf board. For this reason, it is desired to regulate the vertical movement of the shelf board inserted into the groove portion and support the shelf board with good strength.

[0005] Therefore, an object of the present invention is to provide a shelf board device that can regulate the vertical movement of the shelf board portion, support the shelf board portion with good strength, and improve the design property.

Means for Solving the Problems

[0006] To achieve the above objective, the shelf board device according to the present invention comprises: an upper shelf support portion extending in the left-right direction; a lower shelf support portion extending in the left-right direction, facing the upper shelf support portion below the upper shelf support portion with a gap between the shelf support portions; a shelf board portion having its rear portion inserted into the gap between the shelf support portions and attached to the upper shelf support portion and the lower shelf support portion; a restricting portion attached to at least one of the upper shelf support portion and the lower shelf support portion, capable of restricting the vertical movement of the shelf board portion; and a front panel provided in front of the restricting portion. The restricting portion comprises: a pressing portion that penetrates the upper shelf support portion or the lower shelf support portion to which the restricting portion is attached in the vertical direction and presses against the shelf board portion; and an operating portion provided in the space on the side of the upper shelf support portion or the lower shelf support portion to which the restricting portion is attached that is away from the shelf board portion in the vertical direction, and capable of operating the vertical position of the pressing portion.

[0007] In this invention, by operating the operating part of the restricting part to move the pressing part vertically, the shelf board is pressed towards the upper or lower shelf support to which the restricting part is not attached. As a result, the shelf board is sandwiched from above and below by the pressing part and the upper or lower shelf support, or sandwiched between the pressing part of the restricting part attached to the upper shelf support and the pressing part of the restricting part attached to the lower shelf support, thereby restricting the vertical movement of the shelf board. By operating the operating part, the force with which the pressing part and the upper or lower shelf support clamp the shelf board can be adjusted, allowing the shelf board to be supported with good strength. The operating part is provided in a space that is relatively easy to secure on the side of the upper or lower shelf support that is away from the shelf board in the vertical direction, making it easy to design the operating part and the pressing part connected to the operating part in an optimal form for pressing the shelf board with good strength. By providing a front panel in front of the restricting section, the restricting section can be prevented from being exposed to the front, thereby improving the aesthetic design of the shelf device.

[0008] Furthermore, the shelf device according to the present invention has a plurality of support columns that are spaced apart in the left-right direction, and the upper shelf support and the lower shelf support may be installed between the support columns to connect the support columns.

[0009] With this configuration, the members connecting the support columns can be used as the upper and lower shelf supports.

[0010] Furthermore, in the shelf device according to the present invention, the upper shelf support and the lower shelf support may be positioned behind the front end and in front of the rear end of the support column when viewed from the left and right directions.

[0011] This configuration prevents the upper and lower shelf supports from protruding forward or backward beyond the support columns, thus reducing the dimensions of the parts that support the shelves.

[0012] Furthermore, the shelf board device according to the present invention may have a shielding member provided in front of the shelf support spacing, which penetrates in the front-to-back direction and has a groove formed therein into which the shelf board can be inserted.

[0013] This configuration prevents the shelf support sections from being exposed at the front, thereby improving the aesthetic design of the shelf unit.

[0014] Furthermore, in the shelf device according to the present invention, the front panel is provided above and below the shielding member, at least one of which is facing the shielding member in the vertical direction, and the end faces of the shielding member and the front panel that face each other may be horizontal.

[0015] This configuration allows for a smaller gap between the shielding member and the front panel. This improves the aesthetic appeal of the shelf unit and prevents dust and debris from entering the gap between the shielding member and the front panel.

[0016] Furthermore, in the shelf device according to the present invention, the shelf portion may be detachably attached to the upper shelf support portion and the lower shelf support portion.

[0017] By adopting such a configuration, it is possible to easily change the shelf board part to be attached or change the layout of the shelf board part. Since the operating part of the regulating part can be operated to adjust the force for sandwiching the shelf board part according to the shelf board part to be attached, the shelf board part can be supported with good strength.

Advantages of the Invention

[0018] According to the present invention, the vertical movement of the shelf board part can be restricted, the shelf board part can be supported with good strength, and the design property can be improved.

As shown in Figures 3 and 5, the upper shelf support 3 and the lower shelf support 4 are installed between two support columns 21, 21. The upper shelf support 3 and the lower shelf support 4 are joined to each of the two support columns 21, 21. The upper shelf support 3 and the lower shelf support 4 connect the two support columns 21, 21. In other words, the upper shelf support 3 and the lower shelf support 4 are connecting members that connect the two support columns 21, 21. The upper shelf support 3 and the lower shelf support 4 are positioned so as not to interfere with the connecting part 22. The upper shelf support 3 is positioned above the lower shelf support 4 with a gap in between. The upper shelf support 3 and the lower shelf support 4 are manufactured, for example, by processing steel plates.

[0025] As shown in Figures 3 to 6, the cross-sectional shape of the upper shelf support 3 perpendicular to the left-right direction is a C-shape that opens upward.

The left-right dimension of the mounting portion 51 is approximately the same as the distance between the left-right faces of the two support portions 21, 21 that are separated from each other. That is, the left-right dimension of the mounting portion 51 is approximately the same as the left-right dimensions of the front plate portion 71, upper plate portion 72, and lower plate portion 73 of the shielding member 7. The fixing portion 52 is inserted from the front into the shelf board insertion groove portion 711 of the front plate portion 71 of the shielding member 7 and positioned in the groove portion 76 and shelf support portion spacing 23 of the shielding member 7. The mounting portion 51 is positioned in front of the front plate portion 71 of the shielding member 7. The portion of the shelf board 5 in front of the notches 53, 53 is positioned in front of the lateral portion of the shelf board insertion groove 711 of the front plate portion 71 of the shielding member 7.

[0042] The shielding member 7 may be composed of a pair of elongated members that are arranged vertically and extend horizontally, with the shelf portion 5 inserted between these two members. The space between the pair of members corresponds to the shelf insertion groove portion 711. In this case, the shelf insertion groove portion 711 is formed over the entire horizontal length of the shielding member 7. The portion of the shelf board 5 between the notches 53, 53 is positioned behind the front surface 21a of the support column 21, i.e., at the shelf support spacing 23. The portion of the shelf board 5 in front of the notches 53, 53 is positioned in front of the front surface 21a of the support column 21. The rear portion of the portion of the shelf board 5 in front of the notches 53, 53 (the portion close to the notches 53, 53) is positioned between the pair of members of the shielding member 7. This portion may or may not be sandwiched between the pair of members of the shielding member 7 from above and below. The end of the shelf board 5 in front of the notches 53, 53 that faces the front surface 21a of the support column 21 may or may not be in contact with the front surface 21a of the support column 21.

[0043] As shown in Figure 3, the restricting portion 6 includes a bolt 61, a nut 62, and a pressing member 63. As shown in Figures 3 and 6, the nut 62 is positioned in the groove 45 of the lower shelf support portion 4 and fixed to the lower shelf support portion 4. The nut 62 is positioned coaxially with the hole 411 of the upper plate portion 41 of the lower shelf support portion 4. Multiple nuts 62 are provided, spaced apart in the left-right direction, similar to the hole 411 of the upper plate portion 41. The bolt 61 is positioned so that the shaft portion 611 is above the head portion 612, and the shaft portion 611 is inserted from below into the nut 62 and the hole 411 of the upper plate portion 41. The length dimension of the shaft portion 611 is greater than the depth dimension of the groove 45 of the lower shelf support portion 4. The bolt 61 has a shape such that the shaft portion 611 penetrates the upper plate portion 41 and the tip portion 611a of the shaft portion 611 can protrude above the upper plate portion 41. Figure 3 shows the tip 611a of the shaft portion 611 protruding above the upper plate portion 41, and Figure 9 shows the tip 611a of the shaft portion 611 positioned at approximately the same height as the upper plate portion 41.

[0044] The head 612 of the bolt 61 is positioned in the space 25 below the lower shelf support portion 4. The worker can grasp and operate the head 612 of the bolt 61 in the space 25 below the shelf support portion. The head 612 of the bolt 61 corresponds to the operating portion in the claims.

[0045] The pressing member 63 is a long, flat plate extending in the left-right direction. The pressing member 63 is installed overlapping the upper plate portion 41 of the lower shelf support portion 4 with its plate surface facing up and down. A soft member 631, made of, for example, rubber or sponge, is attached to the upper surface of the pressing member 63. The soft member 631 is a linear member extending in the left-right direction. Two soft members 631 are provided, spaced apart in the front-to-back direction. The fixing portion 52 of the shelf plate portion 5 is installed above the pressing member 63.

[0046] As shown in Figure 3, when the bolt 61 is tightened into the nut 62 and the tip 611a of the shaft 611 protrudes upward from the upper plate 41, the pressing member 63 is pushed upward by the shaft 611 of the bolt 61. As shown in Figure 9, when the bolt 61 is loosened and the tip 611a of the shaft 611 moves downward, the pressing member 63 moves downward together with the tip 611a of the shaft 611. As shown in Figure 3, when the bolt 61 is tightened onto the nut 62 and the pressing member 63 moves upward, the fixing portion 52 of the shelf plate portion 5 is pressed against the upper shelf support portion 3 by the shaft portion 611 of the bolt 61 and the pressing member 63. As a result, the fixing portion 52 of the shelf plate portion 5 is fixed to the shelf support portion spacing 23. That is, the shelf plate portion 5 is fixed to the upper shelf support portion 3 and the lower shelf support portion 4. The shaft portion 611 of the bolt 61 and the pressing member 63 correspond to the pressing portion in the claims. Furthermore, if the shelf section 5 is made of glass and subjected to an impact from below, the load resulting from that impact will particularly affect the lower shelf support section 4. However, because the section modulus of the lower shelf support section 4 is smaller than that of the upper shelf support section 3, the lower shelf support section 4 is more prone to deformation. This configuration prevents damage to the shelf section 5. The deformation of the lower shelf support section 4 may manifest as, for example, a widening of the gap between the front panel section 42 and the rear panel section 43, or the entire structure twisting.

[0047] By loosening the bolt 61 and releasing the upward pressure on the fixing portion 52 of the shelf plate 5 by the bolt 61 and the pressing member 63, the fixing of the shelf plate 5 is released, and the shelf plate 5 can be pulled forward and removed from the shelf support gap 23. The shelf plate 5 is detachable from the shelf support gap 23.

[0048] As shown in Figure 3, the front panel 8 is flat. The front surface 81 of the front panel 8 is a decorative surface that is exposed to the front. The front panel 8 is provided above the upper plate portion 72 and below the lower plate portion 73 of the shielding member 7. The upper surface 721 of the upper plate portion 72 and the lower surface 731 of the lower plate portion 73 of the shielding member 7 are horizontal planes. The lower end surface 82 of the front panel 8, which is provided above the shielding member 7, is a horizontal plane. The upper end surface 83 of the front panel 8, which is provided below the shielding member 7, is a horizontal plane. The upper shelf support portion 3, the lower shelf support portion 4 and the restricting portion 6 are located behind the front panel 8 and are not exposed to the front of the front panel 8.

[0049] This section explains how to assemble the shelf unit. The support columns 21, 21 of the support structure 2 are erected and connected by the connecting portion 22. The upper shelf support portion 3 and the lower shelf support portion 4 are attached between the support columns 21, 21. The pressing member 63 of the restricting portion 6 is placed on the upper plate portion 41 of the lower shelf support portion 4. At this time, the distance between the upper surface of the pressing member 63 and the lower surface of the lower plate portion 31 of the upper shelf support portion 3 is greater than the thickness dimension of the shelf portion 5. A soft member 312 is attached to the lower surface of the lower plate portion 31 of the upper shelf support portion 3. A soft member 631 is attached to the upper surface of the pressing member 63.

[0050] Attach the shielding member 7 to the upper shelf support 3 and the lower shelf support 4. The nut 62 of the restricting part 6 is attached to the lower shelf support 4 in advance. The fixing portion 52 of the shelf board portion 5 is inserted from the front into the shelf board insertion groove portion 711 of the front plate portion 71 of the shielding member 7, and positioned inside the groove portion 76 of the shielding member 7 and between the shelf support portion spacing 23. The fixing portion 52 of the shelf board portion 5 is positioned between the soft member 631 on the upper surface of the pressing member 63 and the soft member 312 on the lower surface of the lower plate portion 31 of the upper shelf support portion 3.

[0051] The bolt 61 of the restricting part 6 is fastened to the nut 62 attached to the lower shelf support part 4. The worker grasps the head 612 of the bolt 61 from the space 25 below the shelf support part and manipulates it so that the shaft 611 of the bolt 61 protrudes above the upper plate part 41 of the lower shelf support part 4. The shaft 611 of the bolt 61 presses the pressing member 63 upward and presses the fixing part 52 of the shelf plate part 5 against the upper shelf support part 3. As a result, the fixing part 52 of the shelf plate part 5 is sandwiched between the bolt 61 and the upper shelf support part 3 via the pressing member 63, restricting its vertical movement and fixing it in the shelf support gap 23. The soft member 631 of the pressing member 63 is in contact with the lower surface of the fixing portion 52 of the shelf plate portion 5. The soft member 312 of the lower plate portion 31 of the upper shelf support portion 3 is in contact with the upper surface of the fixing portion 52 of the shelf plate portion 5. In this state, it is desirable that the lower surface of the shelf plate portion 5 is in contact with the lower edge of the shelf plate insertion groove portion 711, so that the shelf plate portion 5 is supported by the support structure 2 at two locations formed in both the lower shelf support portion 4 and the shielding member 7, which are spaced apart in the front-rear direction FR.

[0052] As described above, the shelf board 5 can be removed from the shelf support spacing 23 by loosening the bolt 61 of the restricting part 6 and releasing the pressure applied by the restricting part 6.

[0053] In the shelf device according to this embodiment, by operating the head 612 of the bolt 61 of the restricting part 6 to move the shaft 611 and pressing member 63 of the bolt 61 upward, the shelf 5 is pressed against the upper shelf support part 3, so that the shelf 5 is sandwiched from above and below by the shaft 611 and pressing member 63 of the bolt 61 and the upper shelf support part 3, the vertical movement of the shelf 5 can be restricted. By operating the bolt 61, the force with which the bolt 61, pressing member 63 and upper shelf support part 3 sandwich the shelf 5 can be adjusted, so that the shelf 5 can be supported with good strength. The head 612 of the bolt 61 is located in the shelf support lower space 25 below the lower shelf support part 4, where it is relatively easy to secure space, so it is easy to design the restricting part 6 and the shelf 5 in an optimal form that presses them with good strength. By providing a front panel 8 in front of the restricting section 6, the restricting section 6 can be prevented from being exposed to the front, thereby improving the aesthetic design of the shelf board device 1.

[0054] The upper shelf support section 3 and the lower shelf support section 4 are installed between the support columns 21, 21, respectively, connecting the support columns 21, 21 to each other. With this configuration, the members connecting the support columns 21, 21 can be used as the upper shelf support section 3 and the lower shelf support section 4.

[0055] The front surface of the front plate portion 32 of the upper shelf support portion 3 and the front surface of the front plate portion 42 of the lower shelf support portion 4 are positioned behind the front surfaces (front ends) of the support columns 21, 21. The rear surface of the rear plate portion 33 of the upper shelf support portion 3 and the rear surface of the rear plate portion 43 of the lower shelf support portion 4 are positioned in front of the rear surfaces (rear ends) of the support columns 21, 21. With this configuration, the upper shelf support portion 3 and the lower shelf support portion 4 do not protrude forward or backward from the support columns 21, thus reducing the dimensions of the support structure 2.

[0056] In the shelf board device 1, a shielding member 7 is provided in front of the shelf support spacing 23. This configuration prevents the shelf support spacing 23 from being exposed to the front, thereby improving the aesthetic design of the shelf board device 1.

[0057] The upper surface 721 of the upper plate portion 72 and the lower surface 731 of the lower plate portion 73 of the shielding member 7 are horizontal planes. The lower end surface 82 of the front panel 8, which is provided above the shielding member 7, is a horizontal plane. The upper end surface 83 of the front panel 8, which is provided below the shielding member 7, is a horizontal plane. This configuration makes it possible to reduce the gap between the shielding member 7 and the front panel 8. This improves the aesthetic design of the shelf board device 1 and prevents dirt and dust from entering the gap between the shielding member 7 and the front panel 8.

[0058] The shelf board section 5 is detachable from the shelf support section spacing 23. This configuration makes it easy to change the shelf board section 5 to be installed or to change the layout of the shelf board sections 5. The clamping force on the shelf board section 5 can be adjusted by operating the bolt 61 of the restricting section 6 to match the shelf board section 5 being installed, so that the shelf board section 5 can be supported with good strength.

[0059] Although embodiments of the shelf device according to the present invention have been described above, the present invention is not limited to the above embodiments and can be modified as appropriate without departing from the spirit of the invention. For example, as shown in Figure 10, the shelf board device 1B may be configured such that the restricting part 6B is attached to the upper shelf support part 3B instead of the lower shelf support part 4B, and the shelf board part 5 is pressed from above against the upper plate part 41 of the lower shelf support part 4B using the bolt 61 and pressing member 63 of the restricting part 6B to fix it in place. In this case, a hole 311 is formed in the lower plate part 31 of the upper shelf support part 3, which penetrates vertically, and into which the shaft part 611 of the bolt 61 is inserted. A soft member 632 is provided on the lower surface of the pressing member 63, and a soft member 412 is provided on the upper surface of the upper plate part 41 of the lower shelf support part 4. The head 612 of the bolt 61 of the restricting part 6B is grasped and operated by the worker from the space 24 above the shelf support part.

[0060] The restricting portion 6 may be provided on both the upper shelf support portion 3 and the lower shelf support portion 4. The restricting portion 6 provided on the upper shelf support portion 3 and the restricting portion 6 provided on the lower shelf support portion 4 may be positioned to overlap in the vertical direction, or they may be positioned alternately in positions that do not overlap in the vertical direction. For example, the restricting section 6 may have three bolts 61, with the two bolts 61, 61 on either side being tightened from below the lower shelf support section 4, and the central bolt 61 being tightened from above the upper shelf support section 3. By doing so, the shelf board section 5 is sandwiched between the bolts 61, 61 attached to the lower shelf support section 4 and the bolt 61 attached to the upper shelf support section 3, thereby improving the robustness of the structure that secures the shelf board section 5. Furthermore, by selecting the shelf support section to which the bolts 61 and nuts 62 of the restricting section 6 are provided according to the height at which the shelf board section 5 will be installed, the ease of assembly of the shelf board device 1 can be improved.

[0061] As shown in Figure 11, the shelf device 1C has a front panel 8C on the front of the shelf support portion (lower shelf support portion 4C in Figure 11) which has a restricting portion 6C, while the front of the shelf support portion (upper shelf support portion 3C in Figure 11) which does not have a restricting portion 6C may not have a front panel 8C. In the shelf device 1C shown in Figure 11, the upper shelf support portion 3 is provided at the upper end of the shelf device 1C. The shelf device 1C is, for example, a whiteboard with shelf portions 5 provided along its upper edge, where the upper frame is the upper shelf support portion 3C, the member mounted below the upper frame is the lower shelf support portion 4C, and the whiteboard body is the front panel 8.

[0062] The upper shelf support portion 3 and the lower shelf support portion 4 do not necessarily have to be members that connect the support columns 21, 21 to each other. Specifically, the upper shelf support portion 3 and the lower shelf support portion 4 do not necessarily have to be fixed to the support columns 21. For example, a configuration may be adopted in which the holes 341, 441 formed in the side plate portion 34 of the upper shelf support portion 3 and the side plate portion 44 of the lower shelf support portion 4 are loosely engaged with engaging projections protruding from the inner surface of the support column 21. Alternatively, for example, engaging projections may be formed on the side plate portion 34 of the upper shelf support portion 3 and the side plate portion 44 of the lower shelf support portion 4, respectively, and loosely engaged with engaging holes drilled in the inner surface of the support column 21.

[0063] The front surface 32a of the front plate portion 32 of the upper shelf support portion 3 and the front surface 42a of the front plate portion 42 of the lower shelf support portion 4 may protrude forward of the front surface 21a of the support columns 21, 21, or be flush with the front surface 21a of the support columns 21, 21. The rear surface 33b of the rear plate portion 33 of the upper shelf support portion 3 and the rear surface 43b of the rear plate portion 43 of the lower shelf support portion 4 may protrude rearward of the rear surface 21b of the support columns 21, 21, or be flush with the rear surface 21b of the support columns 21, 21. The shapes of the upper shelf support portion 3 and the lower shelf support portion 4 may be other than those described above.

[0064] A shielding member 7 does not necessarily have to be provided in front of the shelf support spacing 23. The shape of the shielding member 7 may be other than that described above. The upper surface 721 of the upper plate portion 72 and the lower surface 731 of the lower plate portion 73 of the shielding member 7 are not horizontal planes, and the lower end surface 82 of the front panel 8 provided above the shielding member 7 and the upper end surface 83 of the front panel 8 provided below the shielding member 7 are not horizontal planes. A predetermined gap may be provided between the shielding member 7 and the front panel 8. The shielding member 7 does not necessarily have to be fixed to the upper shelf support portion 3 and the lower shelf support portion 4. For example, it may be fixed to or engaged with the support column portion 21 in the same way as the upper shelf support portion 3 and the lower shelf support portion 4. The shelf board section 5 may be fixed in place at the shelf support interval 23 in a way that prevents it from being removed.

[0065] The upper shelf support portion 3, the lower shelf support portion 4, and the pressing member 63 do not necessarily have to have the soft members 312, 412, 631, and 632 attached to them. The soft members may be attached to the shelf board portion 5. The shelf board device 1 does not necessarily have to constitute the fixture unit 11 together with the lifting top plate device 13. The structure of the shelf board device 1 in this embodiment may be used in fixtures or walls on which shelves are provided. [Explanation of Symbols]
