DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame formed by connecting a plurality of (usually four) frames with corner members, and more particularly, to a frame printed on a cloth, a synthetic board, a resin film or the like. The present invention relates to a frame that discloses a mounting structure for a posted object when a printed material such as a poster is used as the posted object.

[0002]

2. Description of the Related Art Heretofore, foreheads composed of a frame formed by connecting four side frames with corner members have been known. In any case, a rigid back plate and a front surface of a posted object are covered in the frame. In this embodiment, an object to be displayed is sandwiched between a transparent plate and displayed.

[0003]

More specifically, these frames are made of aluminum profile extrusion, a back plate such as a corrugated cardboard, an integrated material plate, a veneer plate, an acrylic plate, a PVC plate, or a polycarbonate. It is composed of a front plate made of a transparent resin such as a plate. As the aluminum profile extruded material of the frame, a long material of 6 m or more can be easily obtained. It is weak and the shape and dimensions are only available in limited sizes. Further, it is difficult to obtain a transparent resin plate having a size exceeding a limited standard size, and the price is high (1 m × 2 m).
Above). Further, there are problems such as difficulty in maintaining a heat-resistant (flex-resistant) plane (force for preventing deformation) and a decrease in productivity as the size of the frame increases.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to directly post an object in a frame without using a back plate or a transparent front plate. .

In other words, the background of the present invention is that a material having high water resistance, weather resistance, heat resistance, and mechanical strength, such as synthetic paper, can be used as a sheet for drawing drawings as objects to be posted. is there. These materials can be used like a tent cloth because they do not expand even under tension and have small thermal deformation.

[0006] Therefore, if the object to be posted is displayed in such a manner that the tent cloth is stretched in the frame, it is not necessary to use the back plate or the front plate which causes a high cost.

Conventionally, as a means for applying a tension to an object to be posted as described above, a square of the film is conventionally pulled by a rubber string spring or the like, and a reinforcing rod having rigidity is attached to an upper side and a lower side of the shaft. Means such as posting in the form of a letter are known, but these methods do not provide a good-looking notice.

Further, there is a method in which a posted object is crimped and pinched by lever operation using a lever. In this case, a slight displacement occurs due to the lever operation performed during crimping and pinching, and wrinkles are generated. There is a possibility that the posted object is pulled from the corner of the forehead, so the distance from the corner increases,
In order to prevent such a mechanism from being shown, the width of the frame becomes unnecessarily wide, so that it is very low in feasibility.

[0009]

Protrusions were formed at appropriate positions on the contact surface with the member, and recesses were formed in the corner members for fitting the protrusions of the fixed plate.

The recess has a function of holding the object held by the fixed plate indirectly by the corner member by holding the fixed plate at the corner member. Therefore, since the object to be posted is mounted via the fixing plate, the fixing position of the fixing plate at the corner member is slightly different from the position of the corner of the object to be posted in a state where the object is unfolded normally without tension. By positioning it on the part side, the object to be posted is displayed neatly without damaging the appearance.

More specifically, the recess is formed between a fixed wall surface of the corner member and a movable wall surface capable of moving the protrusion of the fixed plate toward the corner of the corner member with a pressing force. Since the fixing plate moves between the corner members attached to the corners of each frame along the axis of each frame, the object held by the fixing plate is Will be applied in the direction of the corners.

More specifically, the movable wall surface is formed by a movable piece that is sent out along the axis of the frame by rotating the frame, and the movable piece is attached to the axis by rotating the frame. And slide it to the end of the frame.

Accordingly, tension is applied to the upper and lower sides of the object by rotating the upper and lower frames, and tension is applied to the right and left sides of the object by rotating the frames on the right and left sides. Will give. By doing so, the film-shaped object to be posted could be posted in the frame under tension.
