Description

[Technical field]

[0001] The present invention relates to a sub-board arrangement structure, and more particularly to a sub-board arrangement structure in which a sub-board capable of displaying electronic information is slidably attached to the front surface of a main board. [Background technology]

[0002] Patent Document 1 proposes that a sub-board (monitor display) be slidably attached to the front of a blackboard (main board) provided in classrooms in schools and the like. Guide rails are provided above and below the blackboard, and rolling wheels that run on the guide rails are provided above and below the sub-board (monitor display). The rolling wheels allow the sub-board (monitor display) to slide left and right.

[0003] When the sub-board (monitor display) is not in use, it is placed at the left or right edge of the blackboard, but since it occupies part of the blackboard, the usable area of ​​the blackboard is reduced. Therefore, it is preferable to position the sub-board (monitor display) so that it protrudes beyond the left or right edge of the blackboard. Also, since the sub-board (monitor display) can be difficult to see, it is preferable to position it from a low position to a high position. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2009-113446 A Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide a sub-board arrangement structure that allows adjustment of the mounting position of a sub-board that slides along the front surface of a main board. [Means for solving the problem]

[0006] The sub-board arrangement structure of the present invention is a sub-board arrangement structure in which the sub-board is slidably arranged on the front side of the main board, and is characterized in that it comprises a guide rail provided on the main board, a slide member that is slidably arranged in the length direction of the main board on the front side of the main board, a rolling wheel provided on the slide member and running on the guide rail, a guide plate attached to the slide member on the back side of the sub-board and with a length along the sliding direction, and a sub-board support member that is attached to the guide plate so that its position can be changed relative to the guide plate, and to which the sub-board can be attached and detached.

[0007] The guide plate is attached to the slide member eccentrically to one side in a sliding direction, and the sub-board support member is attached to the guide plate eccentrically in the same direction as the one side.

[0008] The guide plate is characterized in that its vertical position relative to the slide member is changeable.

[0009] The guide plate is characterized in that a plurality of the guide plates are arranged above and below the slide member.

[0010] The sub-board support member is characterized in that a plurality of the sub-board support members are arranged in the longitudinal direction of the guide plate.

[0011] The slide member is characterized in that it is made of a frame body assembled into a quadrangle. Effect of the Invention

[0012] According to the sub-board arrangement structure of the present invention, there are provided guide rails on the main board, a slide member on the front side of the main board that can slide in the length direction of the board, a rolling wheel provided on the slide member and running on the guide rail, a guide plate on the back side of the sub-board that has a length along the sliding direction and is attached to the slide member, and a sub-board support member that is attached to the guide plate in a position-changeable manner and to which the sub-board can be attached and detached, so that the sub-board can be freely attached in the up, down, left and right directions of the slide member.

[0013] By attaching the guide plate to the slide member eccentrically to one side in the sliding direction and attaching the sub-board support member to the guide plate eccentrically in the same direction as the one side, it can be arranged so that it protrudes significantly from the right or left end of the main board, and the area of ​​the left or right end of the blackboard that cannot be used on the sub-board can be made smaller.

[0014] The guide plate's vertical position on the sliding member can be adjusted, allowing it to be used when a student has difficulty seeing the sub-board because it is positioned too low.

[0015] A plurality of guide plates, for example two plates, are arranged above and below the slide member, so that the sub-board support member can be reliably supported.

[0016] The sub-board support members are arranged in the longitudinal direction of the guide plate (for example, two pieces), so that the side board can be stably supported.

[0017] Since the slide member is made of a frame assembled in a square shape, it can withstand the mounting strength even if the sideboard is mounted eccentrically. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, the sub-board arrangement structure according to the present invention will be described with reference to the drawings. EXAMPLES

[0020] FIG. 1 is a front view of a sub-board arrangement structure 100 according to the present invention. The main board 1 is a blackboard, and the sub-board 2 is a monitor display. It is not limited to a blackboard, and may be a whiteboard. The sub-board arrangement structure 100 includes a guide rail 3 provided on the main board 1, a frame slide member 4, a rolling wheel 5 provided on the slide member 4 and running on the guide rail 3, a guide plate 6 attached to the slide member 4 on the back side of the sub-board 2 with a length along the sliding direction, and a sub-board support member 7 attached to the guide plate 6 so that the position can be changed and to which the sub-board 2 can be attached and detached. The sub-board 2 is shown in perspective so that the back side can be seen. The sliding direction is the direction in which the sub-board 2 slides, and is indicated by an arrow in FIG. 1.

[0021] In this embodiment, the guide rail 3 is attached to the surface of the blackboard of the main board 1. This is because the blackboard is made of a laminated structure of metal plate and plywood, and the guide rail 3 can be reliably fixed with screws. Therefore, the length of the guide rail 3 matches the length of the main board 1. The guide rail 3 is made of aluminum. As shown in FIG. 1, the guide plate 6 is made of two pieces and is attached eccentrically to one side of the sliding direction of the slide member 4 (the right direction in FIG. 1). The guide plate 6 is made of two pieces, one above and one below. The guide rail 3 is made of aluminum and is soft, so it can be attached to both a main board 1 with a flat surface and a curved main board 1. The guide rail 3 is preferably provided at the upper and lower ends of the main board 1.

[0022] Two sub-board support members 7 are attached symmetrically to the center of the back surface of the sub-board 2. The sub-board support members 7 are fixed to the guide plate 6 at four points. In this embodiment, the guide plate 6 is offset to the right from the slide member 4, and the sub-board support member 7 is attached slightly offset to the right from the center of the guide plate 6, so that the sub-board 2 is positioned to the right of the slide member 4. Therefore, when the slide member 4 is slid and positioned at the right end of the main board 1, the sub-board 2 can protrude significantly from the right end of the main board 1. This allows the blackboard of the main board 1 to be used more widely.

[0023] FIG. 2 is a plan view of FIG. 1. The sub-board 2 protrudes significantly to the right from the right end of the guide rail 3. The slide member 4 is composed of a frame assembled into a square shape, and supports the load of the sub-board 2, which is off-centered to the right. The slide member 4 is provided with two rolling wheels 5 at the upper end and two at the lower end, and the rolling wheels 5 run inside the hollow rectangular shape of the guide rail 3. The number and arrangement of the rolling wheels 5 can be determined appropriately. The sub-board 2 has two sub-board support members 7 attached to its back surface, and the sub-board support members 7 are fixed to the guide plate 6.

[0024] Figure 3 is a right side view of Figure 1. Two upper and lower guide rails 3 are provided on the front side of the main board 1. The guide rails 3 are hollow and rectangular, with rolling wheels 5 running inside the hollow. A slit is provided on the front side of the guide rails 3, and metal fittings that connect the rolling wheels 5 to the slide member 4 are provided on two upper and two lower ends. Two guide plates 6 are provided horizontally in front of the slide member 4. Two sub-board support members 7 are provided vertically in front of the guide plates 6. The sub-board support members 7 are fixed to the rear side of the sub-board 2 with screws.

[0025] FIG. 4 is a front perspective view of the sub-board arrangement structure 100. The sub-board 2 is shown in a see-through manner so that the rear side can be seen. Two guide rails 3 are provided, one above the other. A rectangular slide member 4 made of a frame is provided in front of the guide rails 3. Two guide plates 6 are provided in front of the slide member 4, one above the other. Two sub-board support members 7 are provided in front of the guide plates 6. The sub-board support members 7 are attached to the rear side of the sub-board 2. The positions of the mounting screws 11 of the guide plates 6 can be moved in the vertical direction to attach them to the slide members 4. This allows, for example, the sub-board 2 to be positioned higher than the main board 1.

[0026] FIG. 5 is a rear perspective view of the sub-board arrangement structure 100. The guide rail 3 is omitted in FIG. 5. The slide member 4, guide plate 6, sub-board support member 7, and sub-board 2 are arranged from rear to front. Two rolling wheels 5 are attached to the upper and lower ends of the rectangular slide member 4, which is a frame body. As shown in the pull-out circle, the rolling wheels 5 consist of two main wheels 8 and two follower wheels 9 arranged perpendicularly. The rolling wheels 5 are fixed to the slide member 4 with metal fittings 12. When the sub-board fixing knob 13 is rotated, the sub-board 2 can be fixed to the guide rail 3 with a screw to prevent it from sliding inadvertently.

[0027] Fig. 6 is an explanatory diagram of the sub-board arrangement structure 100 attached to the main board. Fig. 6(A) shows the case where the sub-board 2 is slid to the center of the main board 1, and Fig. 6(B) shows the case where the sub-board 2 is slid to the center of the main board 1. Fig. 6(A) shows the sub-board 2 slid to the center of the main board 1 and in use. Fig. 6(B) shows the sub-board 2 when not in use. The sub-board 2 is offset to the right with respect to the sliding member 4, so that the sub-board 2 can be positioned to protrude from the right end of the main board 1.

[0028] Fig. 7 is an explanatory diagram of a sub-board arrangement structure 100 attached to a main board. Fig. 7(A) shows a case where the sub-board 2 is arranged near the top of the main board 1, and Fig. 7(B) shows a case where the sub-board 2 is arranged near the bottom of the main board 1. As explained in Fig. 4, the position of the mounting screw 11 of the guide plate 6 can be moved in the vertical direction to attach it to the slide member 4, so the sub-board 2 can be positioned either near the top or bottom of the main board 1.

[0029] In this embodiment, the sub-board 2 is arranged on the slide member 4 so as to protrude from the right end of the main board 1, but it can also be arranged so as to protrude from the left end of the main board 1. Although detailed explanation is omitted, which one is used is determined by the availability of the left and right ends of the blackboard. In this embodiment, the sub-board support members 7 are arranged symmetrically at the center of the back surface of the sub-board 2, but they may be arranged eccentrically. This allows the sub-board 2 to protrude further. In this embodiment, the slide member 4 is configured as a frame body, but it can also be configured as a single plate body with a vertical groove. By making the slide member 4 a plate body, twisting and distortion can be reduced compared to the case of a frame body. [Industrial Applicability]

[0030] The present invention is suitable as a user-friendly sub-board arrangement structure since it allows the mounting position of the sub-board, which slides along the front surface of the main board, to be adjusted. [Explanation of symbols]
