Description

[Detailed explanation of the idea] B Industrial application field The present invention relates to a suspension system for transportable bulletin boards.

B. Prior Art Conventionally, blackboards, bulletin boards, and the like (hereinafter referred to as bulletin boards) have been provided with moving legs at the bottom of their board support frames so that they can be moved on the floor.

C. Problems to be solved by the invention In the above-mentioned conventional bulletin boards that can be moved on the floor, the moving legs require a considerable amount of space, which impairs the utilization of the floor space, and It becomes difficult to clean, and furthermore, even when not in use, it occupies a part of the floor surface, causing problems such as getting in the way when the room is being used. Therefore, the present invention aims to solve such problems.

D. Means for Solving the Problems In order to solve the above-mentioned object, the present invention has a rail 1 installed near the ceiling, a roller 2 provided movably along the rail 1, and a A support frame 4 for a bulletin board is suspended from a support rod 3 of No. 2 so as to be rotatable in a plane, and a base end is held by the support frame 4, and the other end is removably engaged with the rail 1, and the engagement The present invention is characterized by comprising a support frame rotation prevention member 5 that prevents the support frame 4 from rotating in a plane.

E. Effect As described above, the support frame rotation preventing member 5
By separating the bulletin board from the rail 1 and pulling the bulletin board together with its support frame 4 in the direction in which the rail 1 is installed, the bulletin board can be moved by the rollers 2 in the direction in which the rail 1 is installed. Then, the support frame rotation prevention member 5 is placed on the rail 1 at the place where the bulletin board is to be installed.
By engaging with the bulletin board, the bulletin board can be installed in a non-rotatable manner at the installation position. Further, by removing the support frame rotation prevention member 5 from the rail 1, the bulletin board rotates in a plane, so it becomes possible to use both sides of the bulletin board, and if the end of the rail 1 is extended close to the wall of the room. Bulletin boards can be stored in a polymeric manner along the wall surface.

F. Example Next, an example of the present invention shown in the drawings will be described. Reference numeral 1 denotes a rail, which is installed and fixed to the ceiling 7 by a bracket 6. The rail 1 is constructed above the position where the bulletin board 8 is to be installed, and extends along the front wall 10 of the room 9 as shown in FIG. D
Furthermore, both ends of the wall extend to both side walls 11 of the room 9. Reference numerals 2 and 2 denote a pair of rollers that are rotatably mounted on the rail 1, and each roller support rod 12, 12 projects downward from the central slot of the rail 1. The lower ends of both roller support rods 12, 12 are connected by a support rod 3. A holding rod 13 is fixed to the center of the support rod 3 so as to protrude downward.
Its lower part is loosely fitted into the center of the support frame 4 that supports the bulletin board 8. Reference numeral 14 denotes a coiled spring located on the outer periphery of the holding rod 13. Its lower end is supported by a nut 15 fixed to the lower end of the supporting rod 13, and its upper end is supported via a bearing 16 that facilitates plane rotation. It is supported by frame 4. Reference numeral 17 denotes steady rest rollers provided on the upper surfaces of both sides of the support frame 4, whose length in the axial direction is the same as the width of the rail 1, and is adapted to be locked to the lower surface of the rail 1. . Reference numeral 5 denotes a support frame rotation prevention member, and its base rod 5a
is inserted into a guide frame 18 fixed to the side frame of the support frame 4 so as to be vertically movable. A spring receiver 19 is fixed to the base rod 5a, and a spring 20 is interposed between the spring receiver 19 and the lower frame 18a of the guide frame 18 to always urge the base rod 5a upward. A locking portion 5b is provided at the upper end of the support frame rotation preventing member 5, and the inner surface thereof is shaped so as to come into pressure contact with both side surfaces of the rail 1 as it rises. The inner surface of the locking portion 5b may be vertical and a rubber plate may be attached to the inner surface, or it may be a tapered surface that widens at the top. The base rod 5a
An operating string 21 is hung from the lower end of the handle.

As described above, in order to move the bulletin board 8, pull the string 21 downward to release the locking part 5b of the support frame rotation prevention member 5 by some distance from both sides of the rail 1. Hold the bulletin board 8 in your hand and pull it in one direction along the rail. As a result, the bulletin board 8 is moved along the rail 1 by both rollers 12 and 17.
Then, when the bulletin board 8 is stopped at a predetermined position,
Since both rollers 12 and 17 clamp the rail 1 from above and below by the force of the spring 15, the bulletin board 8 is held without any wobbling in the front and back directions.
Moreover, movement in one direction of the rail is prevented by the braking action of the rollers 12 and 17. When the string 21 is released, the support frame rotation prevention member 5 moves upward by the force of the spring 20, and its locking portions 5b press against both sides of the rail 1 and clamp the rail 1, so that the bulletin board 8 is flat. Rotation is prevented and bulletin boards 8
Shaking is further prevented. Therefore, when writing by hand as on a blackboard, there is no wobbling and there is no problem in handwriting.

Next, when using the back side of bulletin board 8,
By completely removing the locking part 5b of the support frame rotation prevention member 5 from the rail 1 and rotating the bulletin board 8 manually, the bulletin board 8 can be reversed and used on the back side. Furthermore, when storing the bulletin board 8, by moving it to the side wall 11 of the room and rotating it 90 degrees, it can be stored parallel to the side wall 11, as shown by the chain line in Figure 5. .

G. Effects of the invention As described above, according to the invention, since the bulletin boards 8 are suspended from the rails 1 installed on the ceiling, the usable space on the floor becomes larger compared to conventional ones installed on the floor, and the floor surface can be cleaned easily. It also becomes easier. Further, by setting the rail 1 to any length, curve, or branch, the bulletin board 8 can be placed at a desired position. Furthermore, since the bulletin board 8 is provided so that it can be rotated in plane, it is possible to use both sides, and since the member 5 that prevents this rotation in the plane is provided, the bulletin board 8 can be fixed without wobbling when writing by hand on a blackboard or the like. There is no problem with handwriting work. Furthermore, if the rail 1 is installed up to the side wall of the room, the bulletin board 8 can be rotated in plane to lie along the side wall and overlap the side wall when not in use. Therefore, when the bulletin board 8 is not in use, it can be stored so as not to interfere with the use of the room, and the room can be used effectively.
