It is an object of the present invention to provide a blackboard in which a cleaner can be compactly stored without causing any visual annoyance by simply closing the drawer storing the. [Structure] A drawer for storing a blackboard wiping cleaner in a freely removable manner is attached to the lower part of the powder receiving groove of the blackboard to form the blackboard.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blackboard. Blackboard wipes naturally adhere to the blackboard wipe after wiping the blackboard. Therefore, it is easier to clean the adhered black powder, and it can be cleaned smoothly and quickly, and when not in use, the cleaner can be stored in the drawer so that it can be stored compactly without disturbing the appearance. About the blackboard.

[0002]

[Prior art]

 Originally, this kind of cleaning of the blackboard wiping was done by hitting it with a hand to scatter the black powder, but electric products as shown by the phantom lines in Figures 1 to 3 were developed, and electric suction Is supposed to be cleaned by. Then, an electric cleaner as a single item was placed in one corner of the classroom, and a person on duty on the blackboard carried the blackboard wiper to that corner and sucked in the black powder adhering to the blackboard wipe to clean it.

Alternatively, although not shown, an electric cleaner itself is attached to the lower part of the powder receiving groove of the blackboard, a suction hole is formed in the powder receiving groove, and a blackboard wiper is placed on the upper surface of the powder receiving groove for electric suction. Therefore, it was sometimes cleaned.

[0004]

[Problems to be solved by the device]

 However, in the conventional method of cleaning by placing the electric cleaner as a single item in one corner of the classroom for cleaning, the blackboard wiper must be carried to that location and no measures have been taken for storage. .

In addition, the electric cleaner itself is attached to the lower part of the powder receiving groove of the blackboard, a suction hole is formed in the powder receiving groove, and a blackboard wipe is placed on the upper surface of the powder receiving groove to clean by electric suction. The dust receiving groove is interposed between the cleaner and the blackboard wipe to be cleaned, and the suction action is weakened by the presence of the dust receiving groove.

Therefore, according to the present invention, by simply wiping the blackboard and then pulling out the drawer, it is possible to directly contact the electric cleaner immediately for efficient and smooth cleaning, and when not in use, the drawer containing the cleaner can be cleaned. It is an object of the present invention to provide a blackboard that can be compactly stored without causing any trouble in appearance by simply closing it.

[0007]

[Means for Solving the Problems]

 The present invention constructs a blackboard by attaching a drawer for accommodating the blackboard wiping cleaner so that the blackboard cleaning cleaner can be freely taken out and attached below the powder receiving groove of the black plate.

[0008]

[Action]

 The operation of the above configuration will be described below. In other words, if you want to remove the black powder on the blackboard wipe, simply open the drawer in which the blackboard wiper is stored, turn on the switch to operate the cleaner, and then apply the blackboard wipe directly to the cleaner and gently slide it. Is removed by suction. When the cleaner is not used, the drawer is closed and the cleaner acts as if it is stored in the drawer.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a black board according to the present invention with a drawer open, FIG. 2 is an exploded perspective view of a drawer portion of a blackboard according to the present invention, and FIG. Is.

In the embodiment shown in FIGS. 1 to 3, 1 is a blackboard, 2 is an aluminum frame, 3 is a back frame of the blackboard face plate 4, 5 is a powder receiving groove, 6 is a classroom front wall surface, 7 is a drawer, 8 Is a drawer holding frame, 9 is a rail, and 10 is a blackboard wiping cleaner.

In the embodiment shown in FIGS. 1 to 3, the characterizing feature of the present invention resides in that a drawer 7 for accommodating a blackboard wiping cleaner 10 is attached to the lower part of the powder receiving groove 5 of the blackboard 1. More specifically, referring to the drawings of the embodiments, the drawer holding frame 8 is first attached to the lower part of the powder receiving groove 5 (which is well known and will not be described in detail). The pull-out holding frame 8 is designed so that it can be attached according to the size of the powder receiving groove 5, is formed into a substantially U-shaped cross section, and the attachment pieces 11 are bent at the left and right upper ends of the U-shaped cross section. The mounting pieces 11 are formed with screw holes 12 at predetermined intervals. Further, a pair of left and right rails 9 and 9 are provided on the bottom surface of the drawer holding frame 8. Then, this drawer holding frame is attached to a desired position (the right end in the illustrated example) of the powder receiving groove 5 with a fastener such as a screw 13.

As shown in FIGS. 1 and 2, the drawer 7 may be a drawer in which the blackboard wiping cleaner 10 can be fully filled, or as shown in FIG. 3, when the blackboard wiping cleaner is small, a space is provided in the drawer 7. You can also store a chalk box, etc. Therefore, slide frames 14 and 14 corresponding to the rails 9 and 9 are provided.

The present invention is configured as described above, and the usage of the present invention will be described below. Immediately, the drawer 7 is opened, and a commercially available electric blackboard wiping cleaner 10 is installed in the drawer 7. When the cleaner 10 is not used, the drawer 7 is closed, and when the cleaner 10 is used, the drawer 7 is opened and a switch (not shown) is appropriately turned on to electrically operate the cleaner 10 and wipe the blackboard wiping cleaner 10 with the blackboard wiping cleaner. (Not shown) is put on and lightly reciprocated.

Even if chalk dust collects in the dust collecting bag (not shown) of the blackboard wiping cleaner 10, the cleaner 10 in the drawer 7 does not have to be taken out one by one, but if the drawer 7 is opened, the dust collecting bag will be as usual. Can be taken out and processed.

The present invention is not limited to the above embodiment. That is, it goes without saying that it includes all the components provided with a drawer for freely storing the blackboard wiping cleaner under the powder receiving groove of the blackboard.

EFFECTS OF THE INVENTION Since the blackboard of the present invention is configured as described above, it has the following effects. You can clean the blackboard efficiently, quickly, and reliably directly under the black plate without having to carry the blackboard wipes with the chalk powder on it. Moreover, since it can be brought into direct contact with the blackboard wiping cleaner and slid, it is highly efficient in removing powder. Furthermore, when not in use, the blackboard wiping cleaner does not directly look outward, allowing for beautiful storage and storage. As described above, by providing the drawer capable of storing the blackboard wiping cleaner in the powder receiving groove of the blackboard, it was possible to obtain a surprisingly effective blackboard. This is a useful idea not only for teachers but also for children and students.
