Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction display blackboard for informing construction contents.

[0002]

2. Description of the Related Art In road construction, construction work, etc., the work contents change at each stage of the construction period, so the work contents must be displayed accordingly, and in the past, one blackboard was rewritten each time. Or, another blackboard was prepared and displayed.

[0003]

[Problems to be solved by the invention] Therefore, it may take time and effort to rewrite the display and forget to rewrite it. When preparing another blackboard, it is necessary to manage the blackboard so that it will not be lost, which is a troublesome task. It was In view of this, the present invention facilitates management by connecting four display screens in a single block, and by displaying the necessary display screens in advance so that the display screens can be displayed immediately by replacing them. It was done.

[0004]

[Means for Solving the Problems] Therefore, according to the present invention, two double-sided blackboards, which are blackboards on both sides, are arranged back to back,
Each of the double-sided blackboards is suspended and connected to a suspending member so as to be able to rotate in the vertical direction so as to face each other by 180 degrees, and the suspending member is provided with locking portions in both the upward and downward directions . The hanging member may be divided into two parts along the longitudinal direction so that the two double-sided blackboards can be separated.

[0005]

[Function] Since the two double-sided blackboards are placed back to back, each can be displayed on the outer blackboard, and each double-sided blackboard
When rotated by 0 degrees and the suspending members are turned up, the blackboard surfaces, which are located inside, are located outside, so that the display can be used with a total of four surfaces. It should be noted that in the case where the hanging material is divided into two along the longitudinal direction so that two double-sided blackboards can be separated, each can be used as one double-sided blackboard.

【Example】

The illustrated embodiment of the present invention will be described below. In this example shown in FIGS. 1 and 2, double-sided blackboards 1 and 2 having black and white front and back sides are provided, and as shown in FIG. 3, the lower ends of the hanging dividing members 31 and 32 obtained by dividing the hanging member 3 in the longitudinal direction. Two pieces of blackboards 1 and 2 are hung by connecting them to each other with hinges 4, and two pieces are hung on the hanging piece 3 by mutually attracting them with strong magnetic surfaces 5 fixed to the facing surfaces of the hanging split materials 31 and 32, respectively. The two-sided blackboards 1 and 2 are hung and arranged back to back.

It is to be noted that, on the respective facing surfaces of the suspension division members 31 and 32, a disposition groove 3 of a square frame-shaped suspension locking handle 6 is provided.
3 is vertically cut out, and a finger insertion groove 34 is continuously cut out at a lower end portion between the arrangement grooves 33. Therefore,
The handle 6 can be provided if the handle 6 is housed and arranged before the hanging divided members 31, 32 are put together.
Further, a stopper plate 7 is attached to each side of the double-sided blackboards 1, 2. Further, reference numerals 11 and 21 are adhesion preventing stoppers that protrude to the peripheral portions of the double-sided blackboards 1 and 2.

Next, the operation of this embodiment will be described. First, referring to FIG.
The state is written on the surface of the double-sided blackboard 1 and hung by the handle 6, or the double-sided blackboards 1 and 2 are opened and installed for display as shown in FIG. When the construction progresses and the contents of the construction are changed, the state of FIG. 1 is turned over and the double-sided blackboard 2 is placed on the front side.

Further, as shown in FIG. 5, when the respective double-sided blackboards 1 and 2 are rotated 180 degrees outward and the suspending member 3 is placed on the upper side, the blackboard surfaces of the double-sided blackboards 1 and 2 which are respectively located inside. Since it is located outside, it can be displayed and used on a total of four sides. At this time, as shown in FIG. 6, the insertion groove 3 is turned upward.
Put a finger in 4 and pull out the handle 6 upward.

Further, by separating the suspending members 3 by the magnet surfaces 5, it is possible to divide the suspending dividing members 31 and 32 into a state in which a single double-sided blackboard is provided. You can do it. In this case, the suspending divided members 31 and 32 can be magnetically attached to appropriate portions, which is convenient.

Thus, according to this example, the double-sided blackboards 1 and 2
By rotating 180 degrees, it can be displayed and used on a total of four sides, and can also be used as one double-sided blackboard.

Although the present embodiment is configured as described above, the present invention is not limited to this. For example, the shape and configuration of each double-sided blackboard does not matter. Further, the structure of the suspending member and the structure in which the double-sided blackboards are connected so as to be able to face each other 180 degrees in the vertical direction are also appropriate. As shown in FIG. 7, the suspending member constitutes the supporting frame 8 and the supporting frame 8 A double-sided blackboard may be connected to the rotating body 9 attached to the. In this case, the handle 8 that serves as a locking portion
It suffices to provide 1, 82 at the center of the support frame 8 above and below.

It should be noted that the structure and shape of the engaging portion provided on the suspending member are not limited. In addition, if the hanging material is divided into two parts along the longitudinal direction so that the two double-sided blackboards can be separated, the hanging dividing material should be tightly connected with a buckle metal fitting to form the hanging material. Good.

[0014]

[Effects of the Invention] According to the present invention, the double-sided blackboard can be used for displaying on four sides in sequence by rotating 180 degrees, and the back-to-back state can be maintained without being bulky. is there. Further, in claim 2,
It can also be used as a double-sided blackboard by dividing it.
