Description

Technical Field

[0001] The present invention relates to display boards typified by whiteboards and blackboards, and particularly to a board device that can be used in both vertical and horizontal forms.

Background Art

[0002] In conventional educational settings and meetings, whiteboards and tables used are generally fixed or specialized for single uses. For example, a whiteboard is suitable for information writing on a vertical surface but lacks flexibility in switching uses. On the other hand, meeting facilities such as folding tables are suitable for use on a horizontal surface, but often require much effort for storage and movement. Thus, due to being limited to specific uses, there has been a demand for changing the form according to the usage scenario.

[0003] In response to such a demand, for example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-62787) discloses a multi-purpose board for use in educational settings. This device has a structure combining a foldable board and a workbench. Specifically, the multi-purpose board is divisible, and the divided members rotate to form a flat work surface. Thereby, there is an advantage of enabling various operations such as woodworking, clay work, painting, and the like.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, this technology has a drawback: it does not allow for smooth switching between vertical and horizontal board configurations. Furthermore, it lacks sufficient consideration for convenience during storage and transport, making it difficult to adapt flexibly to different usage environments.

[0006] This invention was proposed to solve the above-mentioned problems and provides a display board that combines flexibility in form, ease of movement and storage, and stability during use. [Means for solving the problem]

[0007] (1) The display board according to the present invention includes a rectangular frame member arranged on a generally vertical plane, a board member arranged inside the frame member and having at least one surface that is erasable, and a pair of pivot members that pivotally support the board member on the frame member, wherein the board member can be positioned on a generally horizontal plane by rotating with respect to the frame member about the pivot members as axes.

[0008] This display board has a structure that allows it to be used on both vertical and horizontal surfaces. Therefore, it can be used as a conventional display board on a vertical surface and as a conference table on a horizontal surface. Because the configuration can be easily switched, a single device can accommodate a variety of applications, providing high convenience in educational settings and conference rooms.

[0009] (2) In the display board described above, the frame member has a sliding and rotating mechanism provided at each of the left and right support portions so that the pivot support member can slide and rotate.

[0010] According to this display board, by providing a sliding rotation mechanism in the frame member, the board member can be easily transformed between a vertical and a horizontal plane.

[0011] (3) In the display board described above, the board member is supported by the pivot support member near the upper ends on both the left and right sides.

[0012] This display board improves the stability of the board components because they are pivotally supported near the upper ends on both the left and right sides. Furthermore, having the pivot points near the upper ends allows for smoother rotation, reducing the user's operational burden.

[0013] (4) The display board further includes leg members that are rotatably provided on the lower side when the board member is positioned on a horizontal plane.

[0014] With this display board, since the leg members are rotatable, when the board members are deformed on a vertical plane and a horizontal plane, the leg members can support the board members while they are being deformed, resulting in stable and easy deformation of the display board.

[0015] (5) In the display board described above, the leg member has a connecting portion that is extendable and retractable and connected to the lower surface of the board member.

[0016] According to this display board, the connecting parts expand and contract when the board material deforms, guiding the deformation. This makes the deformation of the display board stable and easy.

[0017] (6) In the display board described above, the frame member is provided with movable legs that are in contact with the ground in a movable manner.

[0018] This display board features movable legs on the frame, allowing the entire board to be easily moved. This enables smooth movement to different locations such as conference rooms and classrooms, further improving user convenience.

[0019] (7) In the display board described above, the movable legs support the frame member at at least four points.

[0020] According to this display board, since the moving legs have a structure that supports the frame member at at least four or more points, the stability during use is greatly improved. It can be surely installed even on an uneven floor surface, reducing the vibration when using the board member and enhancing the work efficiency.

[0021] (8) In the above-described display board, the moving legs have a locking mechanism for locking the movement on the ground.

[0022] According to this display board, by providing a locking mechanism on the moving legs, it can be fixed when changing the display board, so that the deformation of the display board becomes stable and easy.

Effect of the Invention

[0023] According to the present invention, there is provided a display board that achieves both flexibility in form, ease of movement and storage, and stability during use.

[Modes for carrying out the invention]

[0025] A display board D1 according to the first embodiment of the present invention will be described with reference to the drawings. The display board D1 is a multi-functional device used in educational settings and conference rooms, and can be transformed into both vertical and horizontal forms, and can be used as a desk or table in the horizontal form.

[0026] The display board D1 comprises a rectangular frame member 1 positioned on a generally vertical plane, a board member 2 positioned inside the frame member 1 and having at least one surface that is erasable, a pair of pivot members 4 that pivotally support the board member 2 on the frame member 1, and leg members 3 that are rotatably provided on the lower side when the board member 2 is positioned on a horizontal plane.

[0027] The frame member 1 is a component that forms the support structure for the entire display board D1, and has a rectangular frame portion 11 that is arranged along a roughly vertical plane. Thus, the frame portion 11 is constructed by combining frame members in the vertical and horizontal directions, and supports the board member 2 while it is housed within the frame.

[0028] The frame member 1 is equipped with movable legs 12 that are in contact with the ground in a movable manner. In this embodiment, the movable legs 12 support the frame member 11 with four wheels 13, and the frame member 1 can be moved by the wheels 13 rolling on the ground. The wheels 13 have a conventional locking mechanism (not shown) that locks the movement on the ground.

[0029] The left and right frame portions 11 of the frame member 1 each have a sliding rotation mechanism 14 that allows the pivot support member 4, which will be described later, to rotate and slide. By moving the pivot support member 4 with the sliding rotation mechanism 14, the board member 2 can transition between a state aligned with a vertical plane and a state aligned with a horizontal plane.

[0030] The board member 2 has a rectangular shape adapted to the frame member 1, and at least one of its surfaces 21 is made of a writable and erasable material. Specifically, the writable and erasable material is one that can be used as a whiteboard or blackboard, and has the characteristic of being able to be written on with markers or chalk and erased. The surface is smooth and has excellent durability and maintainability.

[0031] The board member 2 is positioned inside the frame member 1 and is pivotally supported by a pair of pivot members 4 near the upper ends on both the left and right sides. By being pivotally supported by the pivot members 4, the board member 2 has a structure that allows it to rotate relative to the frame member 1.

[0032] The board member 2 can be slid horizontally while rotating by sliding the pivot support member 4. By sliding the board member 2 horizontally, it is positioned in a state that is roughly aligned with the horizontal plane.

[0033] The board member 2 functions as a table or desk when positioned along a horizontal plane. Furthermore, if one of the top surfaces 21 is made of a writable material, it can function as a writable table or desk.

[0034] The board member 2 is supported by a leg member 3 that is rotatably provided on the other surface 22 when the board member 2 is positioned along a horizontal plane. In this embodiment, the leg member 3 has an H-shape and comprises a pair of support legs 31 that form both sides of the H-shape, and the lower ends of the support legs 31 are provided with rollers 32.

[0035] The roller 32, being rotatable and rolling along the ground, guides the board member 2 smoothly as it deforms from a vertical plane to a horizontal plane. This allows the user to unfold the board member 2 with relatively little force.

[0036] Furthermore, the leg member 3 has an extendable guide portion 33 that is extendable and retractable and connected to the lower surface of the board member 2. The extendable guide portion 33 changes its length by extending and retracting in accordance with the rotational trajectory of the board member 2, thereby suppressing rattling and sudden movements during deformation and enabling smooth deformation.

[0037] The pivot members 4 are members that connect the frame member 1 and the board member 2, and realize a structure in which the board member 2 can rotate. Specifically, the pair of pivot members 4 connect the frame member 1 and the board member 2, form a rotational axis for rotating the board member 2, and support the board member 2.

[0038] Furthermore, the pair of pivot members 4 work in conjunction with the sliding rotation mechanism 14 of the left and right frame portions 11 to move the board member 2 between a state aligned with a vertical plane and a state aligned with a horizontal plane.

[0039] Specifically, the pivot member 4 is equipped with a rotatable joint and is designed to allow the board member 2 to rotate smoothly between the vertical and horizontal planes. In addition, the pivot member 4 is slidable in the vertical direction and guides the deformation of the board member 2 in both the vertical and horizontal planes.

[0040] In the display board D1, the board member 2 is aligned with a vertical plane (Figure 1), and the pivot member 4 supports the board member near the upper end of the frame member 1. The pivot member 4 rotates while sliding the sliding rotation mechanism 14 downwards, so that the board member 2 is aligned with a horizontal plane (Figure 2).

[0041] To explain the deformation operation of the display board D1 in more detail, when the board member 2 is standing vertically (see Figure 1), the pivot member 4 is located near the upper end of the frame member 1. When the user applies force to pull the lower end of the board member 2 towards them, the pivot member 4 moves downward along the sliding rotation mechanism 14, rotating the board member 2.

[0042] Simultaneously, the rollers 32 of the leg members 3 roll across the floor, while the leg members 3 support the board member 2. At this time, the telescopic guide section 33 also extends in conjunction, and the board member 2 unfolds so that it can be smoothly tilted toward a roughly horizontal plane (see Figure 2). In this way, the display board D1 is transformed into a shape that can be used as a table.

[0043] Furthermore, to return from the table configuration to the vertical board configuration, the board member 2 is raised and pushed into the frame member 1, causing the pivot member 4 to slide upward and rotate around its pivot point, eventually fitting vertically inside the frame member 1.

[0044] Next, a display board D2 according to a second embodiment of the present invention will be described with reference to Figures 9 to 11.

[0045] As shown in Figures 9 to 11, the display board D2 according to the second embodiment has the same basic configuration as the first embodiment (display board D1), including a frame member 1, a board member 2, a pivot member 4, a sliding rotation mechanism 14, and movable legs 12 (including wheels 13), and can accommodate deformation from a vertical plane to a horizontal plane. However, the display board D2 differs from the display board D1 in the leg member 3.

[0046] In other words, the leg member 203 of the display board D2 has a structure in which the support leg portion 231 has an inverted T shape and rollers 232 are provided at both the left and right ends. Specifically, as shown in Figures 10 and 11, the support leg portion 231 extends downward, and rollers 232 are provided at the left and right ends of the T shape.

[0047] Furthermore, a diagonally mounted telescopic guide portion 233 is provided between the leg member 203 and the back surface (the other surface 22) of the board member 2, and, similar to the first embodiment, plays a role in smoothly guiding the deformation movement of the board member 2.

[0048] By making the leg member 203 in an inverted T shape, the board member 2 can be stably supported from side to side with the center as a pivot point when it is unfolded on a horizontal surface. In addition, since the rollers 232 are located at both ends, the configuration makes it easy to move by rolling and adjust the angle.

[0049] Next, a display board D3 according to a third embodiment of the present invention will be described with reference to Figure 12.

[0050] As shown in Figures 12 and 13, the display board D3 according to the third embodiment has a common movable leg portion 312 and comprises two frame portions 311, two board members 302, two leg portions 303, and two pairs of pivot members 304, and has a structure similar to two display boards D1 (first embodiment) arranged back to back.

[0051] Furthermore, the display board D3 is equipped with two storage compartments 305 between a pair of frame sections 311. In this embodiment, the storage compartments 305 have a drawer structure and can be pulled out by pulling the handle 351. However, the storage compartments 305 may be simple shelves or the like.

[0052] In the display board D3, each frame member 301, each board member 302, each leg 303, and each pair of pivot members 4 operate in the same manner as in the first embodiment. With both board members 302 aligned with the vertical plane (Figure 12), the pivot members 304 support the board members near the upper ends of each frame member 301. The pivot members 304 rotate while sliding the sliding rotation mechanism 314 downwards, causing the board members 302 to align with the horizontal plane (Figure 13). As a result, the board members 302 become a table equivalent to two tables, functioning as a large table. <Variations>

[0053] In this embodiment, the pivot member 4 was described as rotating and sliding up and down in conjunction with the sliding rotation mechanism. However, the display board may also be configured such that the pivot member is placed at a predetermined height, and the board member 2 becomes a table or desk simply by rotating it.

[0054] In this embodiment, the movable leg 12 was described in a configuration in which it supports the frame 11 with four wheels. However, the movable leg 12 may have only two wheels and a stand in the center, or conversely, the number of wheels may be increased.

[0055] In this embodiment, the board member was described as having one side that is a writable and erasable whiteboard or blackboard. However, the board member may be an electronic blackboard (digital screen or touch panel) in addition to a whiteboard. Furthermore, the other side may be coated with a screen projector coating (anti-reflective or diffuse).

[0056] In this description of the tree form, the leg members are described in an H-shape or inverted T-shape. However, the leg members may also be in other shapes, such as X-shape (cross legs) or U-shape.

[0057] In this embodiment, the storage section 305 has been described as a drawer structure that can be pulled out by a handle 351. However, the storage section 305 may also be a shelf structure without partitions on the sides. [Industrial applicability]

[0058] This invention can be used in display boards. [Explanation of Symbols]
