Description

  The present invention relates to a chalk for a construction blackboard and a blackboard eraser storage case installed at a construction site for civil engineering and construction.

  Conventionally, on construction blackboards that describe and display construction details, the chalk and blackboard eraser used for this have been placed in a box fixed or installed on the back side of the construction blackboard.

  When the box installed on the back side of the construction blackboard described above was used, there were the following problems.

  When taking a picture of the construction progress, it is necessary to take a photograph including the construction blackboard where the details of the construction are entered, but the construction site has many places with poor environment such as scaffolding, among which the construction blackboard is installed When doing so, it often happened that the chalk and blackboard eraser were dropped from the box and lost. Also, the box fixed and installed on the construction blackboard often came off.

  In order to solve such problems, construction personnel put chalk or blackboard eraser in pockets, etc., but the chalk is easy to break, and blackboard eraser chalk powder adheres to the inside of the pocket and drops even after washing. There were problems such as difficulty. In addition, when it rains, the chalk and blackboard eraser get wet, and it has become impossible to use afterwards.

  The present invention is intended to solve the above-mentioned problems inexpensively and reliably.

  That is, the invention of claim 1 is a transparent case for storing chalk and a blackboard eraser, provided with a lid, affixed with a magic tape on the back of the lid and the front surface of the case body, and on the back of the case body. It is a transparent case for storing chalk and blackboard, which is characterized by having a tape attached. This is because the use of the transparent case makes it possible to accurately know the state of choke consumption with the naked eye. In addition, rain can be prevented from entering during rainy weather by providing a lid, and velcro can be securely prevented from entering even during wind and rain by attaching velcro to the back of the lid and the front surface of the case body. is there. In addition, the velcro attached to the back of the case body is attached to the garment, for example, with the opposite side of the male / female pair corresponding to this tape, and the case body is fixed to the garment with both velcro tapes. And can be carried around.

  Further, according to the invention of claim 2, the dimensions of the case main body are 70 to 100 mm in length, 70 to 100 mm in width, and 15 to 25 mm in thickness. It is a transparent case. Here, the reason for defining the dimensions of the case body will be described. A typical choke size is about 12 mm in diameter and about 80 mm in length. On the other hand, the size of a general small blackboard eraser is about 40 mm in length, about 80 mm in width, and about 20 mm in thickness. The case can be stored in a case where a blackboard eraser is placed vertically and two chalks are stored next to it, or a blackboard eraser is placed horizontally and two chalks are stored on it. Even in cases, it is as small and wasteful as possible from the viewpoint of ease of carrying and handling, and it is stored neatly to prevent blackboard erasing and chalk movement inside the case to prevent chalk breakage and ease of removal, etc. The size is also taken into consideration.

  As described above, the chalk of the present invention and the transparent case for storing the blackboard eraser can be carried by being attached to clothes or the like, so that they can be prevented from being lost on a construction site with poor scaffolding without being attached to the construction blackboard. In addition, the chalk does not break because it cannot be put in the pocket, and the inside of the pocket does not become dirty with chalk powder. By attaching the Velcro to the back of the lid and the front surface of the case body This prevents the chalk and blackboard eraser from getting wet when it rains. In addition, the Velcro tape attached to the back of the case body is affixed to the clothing, for example, with a Velcro tape that has a male / female opposite surface corresponding to this tape, and the case body is fixed to the clothing with both Velcro tapes. And can be carried easily.

  In addition, by defining the dimensions of the case body, it is easy to carry, easy to handle and saves unnecessary space, and it is stored neatly to prevent blackboard erasing and chalk movement inside the case to prevent chalk breakage and easy removal. Became possible.

  An embodiment of a transparent case for storing chalk and blackboard according to the present invention will be described with reference to the drawings.

  A side view of the transparent case for storing the chalk and the blackboard is shown in FIG. 1, and a plan view is shown in FIG. In both figures, a lid 2 is provided on the upper portion of the case body 1 and a magic tape 3 is attached to the back surface of the lid, and a magic tape 4 is adhered to the front (front) surface of the case body to prevent rain from entering. prevent. Further, the magic tape 5 is also attached to the back of the case body. Then, a velcro tape having a male / female opposite surface corresponding to this tape is attached to, for example, clothes, and the case main body is fixed to the garment with both velcro tapes and can be easily carried. When the construction blackboard is installed on the wall surface of the construction site, the case of the present invention can be attached to the wall surface next to the construction blackboard.
