Description

The present invention relates to a writing board device with an optional member having a writing board such as a white board or a blackboard, having a writing surface on the surface.

Conventionally, various writing boards such as whiteboards and blackboards have been proposed in which a paper clip is provided at the top of the board body and a powder receiver is provided at the bottom to receive writing marks (for example, Patent Document 1, Patents). Reference 2).
Japanese Utility Model Publication No. 7-2086 (FIG. 1) Japanese Utility Model Publication No. 3-47909 (FIGS. 1 and 2)

  However, in the above prior art, since the paper clip and the powder receiver are integrally fixed to the board body, the cost of the writing board increases, and the writing board has new functions such as a self-supporting function and a hanging function. If you try to add it, it will further increase the cost.

  In addition, the paper clip and powder receiver have been improved one after another, but it is difficult to replace only the paper clip and powder receiver, so the paper clip and powder receiver attached to the old writing board are difficult. There is a problem that it has to be used without being improved.

  In addition, when rearranging multiple writing boards so that they can be easily viewed, individual writing boards may not necessarily require paper clips or powder trays. However, the conventional writing board has an integrated paper clip and powder receiver, so it cannot be removed, resulting in a costly board with unnecessary paper clips and powder receivers. There is a problem that it must be used.

In view of the above problems the prior art has, by the way can be detachably mounted to various optional member to the board body, optional member that enables expansion functions at low cost An object of the present invention is to provide an attached writing board device.

According to the present invention, the above problem is solved as follows.
(1) In a writing board device with an optional member having a writing board with an upper frame and a lower frame attached to the upper and lower parts of the board body facing the vertical direction with a writing surface, either or both of the upper frame and the lower frame on the back side of the back surface of the optional member to form engageable engaging groove engages the optional member in this engaging groove and downward pieces under Rishide by engaging groove of the upper frame, Rutotomoni provided a magnet for adsorbing, the backward projecting distance of from the back of the upper frame in the magnet, is larger than the front-rear direction of the thickness of the mounting portion in the optional member to be engaged with the engaging groove.

(2) In the above item (1), the engaging portion provided on the paper clip member that clips and hangs the upper end portion of the paper as an optional member is engaged with the engaging groove of the upper frame of the writing board.

(3) In the above item (2), the paper clip member extends backward from the upper end of the paper clip portion disposed on the front surface of the upper frame and above the upper frame, and on the rear surface of the upper frame. And an attachment portion having an engaging portion formed on the front surface of the lower end portion.

(4) In any one of the above items (1) to (3), one of the optional members engaged with the engaging groove of the upper frame is a hooking member that can be hung by hanging the board body.

(5) In any one of the above items (1) to (4), one of the optional members to be engaged with the engaging groove of the lower frame is a powder receiving member that receives writing debris below the writing surface.

(6) In any one of the above items (1) to (5), one of the optional members to be engaged with the engagement groove of the lower frame is a self-supporting leg that makes the board main body self-supporting.

(7) In any one of the above items (1) to (6), the upper and lower sides of the engaging groove formed in the upper frame or the lower frame protrude opposite to each other or both. A protruding piece is formed, and an engaging portion that can be engaged with the protruding piece is formed on the option member.

(8) In any one of the above (1) to (7), an attracting magnet is attached to the back surface of the lower frame .

According to the present invention, the following effects can be achieved.
(a) According to the first aspect of the present invention, the engagement groove capable of engaging the optional member is formed on the back surface of one or both of the upper frame and the lower frame. Thus, the board body can be manufactured at a low cost with a simple structure, and various functions can be added to the writing board for various applications. Furthermore, since the option member and the board body are independent, it is possible to improve only the option member and add a new function at a low cost. Moreover, the upper part of a writing board can be made to adsorb | suck to the wall surface member etc. of a magnetic body with a magnet, and can be supported.

  (b) According to the invention described in claim 2, since the optional member engaged with the upper frame is the paper clip member, the paper can be suspended.

  (c) According to the invention described in claim 3, the paper clip member is firmly attached so as to straddle the upper frame, and the appearance is good.

  (d) According to the invention described in claim 4, since the optional member is the hook member, the board body can be used by being hooked on, for example, a low partition.

  (e) According to the invention described in claim 5, since the optional member is the powder receiving member, it can receive writing.

  (f) According to the invention of claim 6, since the optional member is a self-supporting leg, the board body can be made self-supporting.

  (g) According to the seventh aspect of the invention, since the projecting piece projecting opposite to one or both of the upper and lower sides of the opening portion of the engaging groove is formed, the engaging portion of the option member is engaged with the projecting piece. Can be securely attached to the upper and lower frames.

(h) According to the eighth aspect of the present invention, the lower part of the writing board can be supported by being attracted to the wall member or the like of the magnetic material by the magnet.
