Description

[Detailed explanation of the idea]

[Field of Application of the Invention] The present invention relates to a wall-mounted blackboard, whiteboard, etc., which is equipped with a sliding door and is easy to write on and erase (hereinafter collectively referred to as a blackboard). [Background of the invention] Wall-mounted blackboards are widely used in classrooms, offices, conference rooms, etc., but when installed in conference rooms,
Particularly in large reception rooms and conference rooms where guests are invited to have meetings, doors are installed to make the blackboard look like furniture when it is not in use. Blackboards can be roughly divided into two types depending on the type of door that is installed to cover the blackboard: sliding boards that have a sliding door with rails, and folding boards that have hinged doors that open. . The slide board has the advantage that it can be opened and closed even if there is an obstacle in front of the blackboard, but it has the following difficulties. FIG. 1 is a schematic front view of an example of a slide board. Of the two doors 2a and 2b provided to cover the blackboard body 1, the right door 2a is opened and the left door 2b is closed. The situation is depicted. 3 is an upper frame member supporting the blackboard main body 1, 4 is a lower frame member, and 5b and 5a are left and right frame members. Reference numeral 6 denotes a storage shelf provided for storing markers, erasers, etc. FIG. 2 is a schematic front view with the left and right doors 2b and 2a closed. From this state, doors 2b and 2a
Slide the rail member 7 left and right to open it.
must be fixed to the wall. Even if a door is provided to cover the blackboard, if the rail member 7 is exposed on the wall, the furniture-like atmosphere will be spoiled. Efforts have been made to improve the appearance. In order to effectively utilize the area occupied by the door pocket, attempts have also been made to provide a bulletin board on the surface of the door pocket. However, the conventional sliding board with a sliding door requires fixing members to be installed on both left and right walls, and is therefore subject to restrictions on installation location. In particular, if the rail member cannot be installed on the wall due to the relationship with the furniture in the room or the structure of the room, it has been impossible to install the conventional slide board. [Purpose of the invention] This invention was made in view of the above circumstances.
To provide a slide board equipped with a sliding door that does not require the installation of fixing members on either the left or right sides of the blackboard. [Summary of the invention] In order to achieve the above object, the slide board of the present invention includes a three-stage slide rail between the member supporting the blackboard body and the door covering the blackboard, and A pair of outer rails is attached to the horizontal member supporting the main body of the blackboard and the horizontal member forming the door, respectively, and the above-mentioned method is carried out without fixing the rail means to the side of the wall surface on which the blackboard is installed. The feature is that the door can be opened and closed against the blackboard surface by sliding left and right. FIGS. 3 to 5 are explanatory diagrams of the principle of the present invention. FIG. 3 is a schematic front view of a slide board to which the present invention is applied. This slide board has a symmetrical structure, and this figure shows only the right half of the center line OO. Reference numeral 1' represents a blackboard portion including the blackboard main body and a frame member. 2a is the door on the right. A three-stage slide rail 8 is interposed between the upper edge of the right door 2a and the upper edge of the blackboard portion 1', and the door 2a is suspended via the three-stage slide rail 8. The dimension L indicates the horizontal length of the right half of the blackboard portion 1', and corresponds to 1/2 of the total length of the blackboard portion 1'. Figure 4 is shown to explain the structure of the three-stage slide rail, and is a commercially available three-stage slide rail.

FIG. 2 is a cross-sectional view of [Akiuride 3-stage slide rail (trade name)]. The three-stage slide rail is a well-known device that is widely used for pulling out side desks, etc., and has a pair of outer rails 8.
It has a structure in which the inner rails 8a and 8b hold the middle rail 8c via the ball 8d, and the pair of outer rails 8a and 8b are guided in the longitudinal direction while keeping parallel to each other, and can be moved with a relatively small force. Can withstand high loads. Therefore, the door 2a can be slid by approximately the dimension L in the left-right direction as indicated by arrows A and B in FIG. 5 while suspended on the three-stage slide rail 8. Lower outer rail 8 fixed to blackboard part 1'
If the upper outer rail 8a fixed to the upper edge of the door 2a moves by the distance L' without moving the inner rail 8c,
holds the ball 8d and moves in parallel by L'/2 in the same direction, its left half is supported by the lower outer rail 8b through the ball, and its right half is supported through the ball by the lower outer rail 8b. Supports the upper outer rail 8a. Thereby, the door 2a to which the upper outer rail 8a is fixed is held suspended. In the above-mentioned principle explanatory diagram (Fig. 3), the three-stage slide rail 8 is provided near the upper edge of the blackboard body 1 and the door 2a, but it is placed near the lower edge as indicated by 8' in the imaginary line in the same figure. [Embodiment of the invention] Figures 6 to 8 show an embodiment of the slide board of the invention, and Figure 6 shows a horizontal slide board. A sectional view, FIG. 7 is an external side view, and FIG. 8 is a vertical sectional view.The blackboard main body 1 and the right door 2a are given the same drawing reference numbers as in FIG. 1 showing the general structure of the slide board. , upper frame material 3, lower frame material 4, right frame material 5
a is a structural member similar to that in a conventional slide board. The upper frame material 3 supporting the blackboard body 1 and the door 2
A three-stage slide rail 8 is interposed between the horizontal frame member 2a _-1 on the upper edge of the outer rail 8a and the horizontal frame member 2a-1.
At a _-1 , the outer rail 8b is fixed to the upper frame member 3, respectively. L on the inside surface of the horizontal frame material 2a _-2 on the lower edge of the door 2a.
Attach the guide shoe 9 with a shaped cross section,
A guide groove 4a is provided on the lower surface of the lower frame member 4, and the guide shoe is slidably fitted therein. Reference numeral 10 denotes a hook member for wall mounting, which is fixed to the upper frame member 3. With the above configuration, the blackboard main body 1 and its attached members (frame materials, etc.), as well as the doors 2a, 2b and their attached members, are connected, and the blackboard main body 1 and its attached members are connected, and the blackboard main body 1 and its attached members are connected, and the blackboard body 1 and its attached members are connected, and the blackboard body 1 and its attached members are connected, and the blackboard main body 1 and its attached members (frame materials, etc.) are connected, and the blackboard body 1 and its attached members are connected.
It becomes a separate assembly and is convenient for handling. To attach the above assembly to the wall 11,
The hanging member 12 and the L-shaped metal fitting 13 shown in the figure are attached to the wall surface 11 in advance, and the hook member 10 is engaged with the hanging member 12 as shown in the figure, and the lower frame member 4
All you have to do is place it on the L-shaped fitting 13. Furthermore, the assembly can be easily removed from the wall and reattached, making it convenient for cleaning or redecorating the room. [Effects of the invention] As detailed above, the slide board of the invention has a three-stage slide rail between the member supporting the blackboard main body and the door, and a pair of outer rails of the slide rails are connected to the blackboard. By attaching it to the horizontal member that supports the main body of the machine and the horizontal member that makes up the door, the door can be supported parallel to the wall without the need to install a fixing member such as a rail on the side of the wall where the blackboard is installed.・It has an excellent practical effect of being able to open and close the blackboard surface by guiding it.
