DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing panel wall mounting structure in which a frame material is provided around a writing face material.

[0002]

2. Description of the Related Art Conventionally, a writing panel in which a frame material is provided around a writing surface material such as a blackboard, a whiteboard, or a magnetic panel is well known. In addition, as a structure for attaching such a writing panel to a wall surface, a hanging bracket is fixed to a frame material on the upper part of the writing panel with a screw or the like, and the hanging bracket is tied with a hanging string, and a Western fold or a Western lamp mounted on the wall side is attached. A method of hooking and attaching a hanging string to a fixture such as the above is often used.

The magnetic panel has a structure in which a storage chamber for storing a magnetic substance and a liquid is disposed between a transparent front plate and a back plate, and a magnet is brought close to the front panel of the magnetic panel to house the magnetic panel. The magnetic material is sucked and the magnetic material is arranged on the front plate side to make a display line, or the magnet is brought close to the back plate to suck the magnetic material and the display of the magnetic material arranged on the front plate side is erased.

[0004]

In the conventional structure, since the mounting operation is performed at the upper portion of the writing panel, the operation is difficult when the size of the writing panel is large, and the writing panel is supported only by the upper portion. Because of the structure
When subjected to an earthquake or wind pressure, the writing panel swings like a pendulum centering on the fixing bracket, and the swing gradually increases.The vibration causes the fixing bracket or the hanging bracket to detach or break, causing the writing panel to fall on the ground. Worrying about falling,
Alternatively, there is a problem that a gap is generated between the upper frame material to which the hanging bracket is fixed and the writing surface material. In addition, since the positions of the fixing bracket and the hanging bracket are fixed, once the writing panel is attached to the wall surface, there is a problem that it takes time and effort to shift the writing panel to the left or right. Among the above-mentioned magnetic panels, in particular, the latter magnetic panel is provided with an iron plate on the back surface side of the panel in order to efficiently apply the magnetic force of the magnet member approaching from the surface plate side to the magnetic body in the housing chamber. When the writing or erasing is completed and the magnet member is about to be separated from the surface plate, the iron plate of the magnetic panel is attracted to the magnet member, and the writing panel is centered on the wall mounting bracket. There was a real problem that emerged more.

In view of the above-mentioned circumstances, the present invention can easily attach a large-sized writing panel, and can attach the writing panel integrally to a wall surface. It is an object of the present invention to provide a writing panel mounting structure that allows the writing panel to be shifted left and right even after the panel is mounted on a wall surface.

[0006]

Next, a description will be given of a wall mounting structure for a writing panel according to the present invention devised to solve the above-mentioned problems. "1. In a wall mounting structure of a writing panel in which a frame material is disposed around a writing surface material, the writing panel includes an upper metal fitting and a lower metal fitting fixed to the wall, and the writing panel is provided on an upper surface of the upper frame material. A downward groove which forms a continuous upper groove and forms a continuous lower groove on the lower surface of the lower frame material, and the upper bracket is folded upward on the upper bracket fixing piece and the upper part of the upper bracket fixing piece. And the lower metal fittings,
A lower metal fitting fixing piece and an upright piece rising from the lower metal fitting fixing piece are formed, a female screw portion is formed on the upright piece, and a screw is screwed into the female screw portion, and a washer is provided at the upper end of the screw. Arranged, a washer is formed with a parallel surface parallel to the upright piece, a through hole is drilled in the parallel surface, a screw is inserted into the through hole, and the upper end of the screw is rockable so as to be in a retaining state. A projection is formed on the upper surface of the parallel surface on one side of the upper bracket fixing portion, and the projection is brought into contact with the lower metal fixing portion to stop rotation of the washer, and the upper portion stands on the parallel surface upward. A tongue piece is formed, and the lower tongue piece of the upper fitting is locked to the upper groove of the upper frame material, and the screw is locked while the upper tongue piece of the lower metal fitting is locked to the lower groove of the lower frame material. By tightening the screws, the writing panel is pushed up and the upper and lower brackets are Characterized by comprising clamping the writing panel. 2. The upward tongue piece formed on the washer is formed on the lower metal fitting fixing side of the lower metal fitting from the center position of the screw inserted into the through hole of the washer. 3. On the parallel surface of the washer, an upward second tongue piece rising upward from the upward tongue piece is formed at a position opposite to the lower bracket fixing piece, and at least a lower upward frame material of the writing panel is A second groove portion facing the tongue piece is formed. 4. A recess is formed in the upper outer peripheral edge of the through hole formed on the parallel surface of the washer, and a screw is inserted into the through hole, and the upper end of the screw is swaged inside the recess to be a swingable retaining state. It is characterized by. "

In the present invention, the writing panel is sandwiched between the upper metal fitting and the lower metal fitting because the upper frame material and the lower frame material can be brought into close contact with the writing face material. Further, by integrally attaching the writing panel to the wall surface, it is possible to prevent the writing panel from swinging like a pendulum when receiving an earthquake or wind pressure. Also,
Locking the downward tongue of the upper bracket and the upward tongue of the lower bracket in the groove of the frame material prevents the writing panel from shifting in the front-rear direction, and the locking portion when the writing panel is viewed from the front. Is not to show.

[0008] In addition, the writing panel is clamped by screwing the lower metal fitting so that the upper metal fitting and the lower metal fitting are fixed to the wall surface in advance even when the writing panel is too large to reach. This is because, for example, the writing panel can be easily pinched and fixed from below. In addition, since the washer in contact with the frame material supports the weight of the writing panel, pressure is always applied to the screw from above, so that the screw can be prevented from loosening.

The protrusion of the lower metal fitting is brought into contact with the fixing piece to prevent rotation of the washer so that when the screw is tightened, the writing panel is surely lifted up without rotating the washer. In order to

Further, the washer and the upper end of the screw are made to be able to swing so as to prevent the writing panel from being slidable when the writing panel is placed on the lower metal fitting and the left and right sides of the writing panel are different. This is because the variation can be absorbed by the swing of the washer of the lower fixing bracket.

[0011] Further, the formation of the continuous upper groove portion on the upper surface portion of the upper frame material and the formation of the continuous lower groove portion on the lower surface portion of the lower frame material are performed by a writing panel within a range of the groove portion with respect to the fixing bracket. Can be shifted in the left-right direction.

The upward tongue piece formed on the washer is formed on the lower metal fitting fixing side of the lower metal fitting from the center position of the screw inserted through the through hole of the washer, so that the writing panel is sandwiched between the upper metal fitting and the lower metal fitting. Then, when the lower groove presses the upward tongue by the force of the pinching, the upward tongue is deeper than the center position of the screw, so the washer is inclined so that the wall surface side is lowered, and as a result, the lower part of the writing panel This is because it can be firmly attached while being pressed against the wall surface side.

[0013] Further, an upward second tongue piece rising upward from the upward tongue piece is formed on a parallel surface of the washer at a position opposite to the lower metal fitting fixing piece, and at least a lower frame material of the writing panel includes: The second groove facing the upward second tongue is formed by hooking the upward second tongue into the second groove when the lower frame material of the writing panel is engaged with the lower metal fitting, and is used as a base point. By rotating the writing panel about the base point, the writing panel can be easily aligned with the mounting position of the writing panel.

A recess is formed in the upper outer peripheral edge of the through hole formed in the parallel surface of the washer, and a screw is inserted into the through hole, and the upper end of the screw is swaged inside the recess to be able to swing. The stop state is used to prevent the frame material from coming into contact with the caulking portion when the frame material is placed on the lower fixing bracket.
