The present invention relates to a hanging board, and more particularly to a hanging board that can be easily assembled by a clasp or pedestal by improving the structure of the frame coupled to the rim.

In general, the board is installed on the wall is widely used for advertising, posting or memo. In particular, in recent years, a marker pen board (normal 'white board') using a marker pen mixed with pigment components in oil as a writing instrument has been developed and widely used for education and memo. Such boards are typically installed in such a way that they are hung on nails or screws embedded in the wall.

FIG. 1 is an exploded perspective view of a hanger board (a white board for a marker pen) most commonly used in the related art, and FIG. 2 is a cross-sectional view taken along the line A-A of FIG.

Referring to FIGS. 1 and 2, in general, a board may include a main board (1) capable of writing (for note) or a sticker or the like (for a billboard or bulletin board), and the main board (1). Up and down, left and right frame (2) coupled to the edge of the main frame (1) supporting the main board (1), the corner joint member (3) connecting the frame (2), and the upper frame (2) to be installed on a wall Has an assembled latch 4. As shown in the drawing, the memo board (marker pen white board) has a structure in which a pedestal 5 for placing an eraser E, a marker pen P, and the like on the lower frame 2 is installed. In the case of the advertisement board and the bulletin board, the main board 1 is mainly a cork board press-molded with a cork chip, and in the case of a memo board, an acrylic resin board or the like is mainly bonded to a wood plywood. In this case, as shown in FIG. 2, the frame 2 has a cross-sectional shape of a 'c' shape to be fitted to the main board 1.

However, as shown in FIGS. 1 and 2, the board according to the prior art has the following problems as the subsidiary materials assembled to the frame 2 are assembled by screws S.

Specifically, conventionally, when assembling the clasp 4, the pedestal 5 and the main board 1 to the frame 2, the screw (S) is used, with the trouble of assembling the screw (S) at this time The assembly productivity and price are increased by the price of the screw (S) itself, there is a problem that the screw (S) can be easily loosened, the bonding force is not solid.

In addition, the board according to the prior art, if two clasps 4 are assembled to the upper frame 2 at predetermined intervals, due to the hassle of fastening the screws (S) to the wall surface in accordance with the spacing of the clasps (4) There was a problem with the neck.

The present invention has been invented to solve the problems of the prior art as described above, and by improving the structure of the frame, the clasp or pedestal is firmly and easily assembled without screws, and the clasp or pedestal can be slid The purpose is to provide a hanging board.

In order to achieve the above object, the present invention is connected to the main board, the upper and lower left and right frames coupled to the edge of the main board, the frame and the joint member coupled to the edge of the main board, and to be installed on the wall In the hanging board comprising a latch assembled to the top frame,

At least a top frame of the upper, lower, left, and right frames is formed with a 'T' shaped assembly groove, and the clasp is formed with a 'T' shaped fitting portion corresponding to the 'T' shaped assembly groove at its lower end, and the clasp is the upper frame. It is fitted in the 'T' shaped groove of the assembly and provides the assembled hanger board.

In addition, the hanger board according to the present invention includes a base which is assembled to the bottom frame, the bottom frame is also formed in the 'T' shaped assembly groove of the same structure as the top frame, the 'T' shaped on the pedestal A 'T' shaped end portion corresponding to the assembly groove is formed, and the pedestal is fitted into the 'T' shaped assembly groove of the lower frame and has an assembled structure.

In addition, the hanging board according to the present invention has a structure in which a packing member is inserted between the rear side wall of the frame and the main board.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention. The accompanying drawings show exemplary embodiments of the present invention, which are provided merely to illustrate the present invention in detail, and thus the technical scope of the present invention is not limited thereto.
