DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for extending a signboard in which a sheet displaying required characters, figures, and the like is extended on a frame to be attached to a building, a wall or the like.

[0002]

2. Description of the Related Art As a conventional signboard, there is a signboard shown in FIGS. In this signboard, long horizontal frame rods 1 to 4 are arranged at positions forming the vertices of a vertical rectangle, two horizontal frame rods 1 and 2 arranged on the upper side, and two horizontal frame rods arranged on the lower side. Frame rods 3, 4 and two horizontal frame rods 2, 3 arranged on the upper and lower sides of the rear side
A sheet 8 displaying required characters, graphics, and the like is stretched over a frame body having horizontal frame rods 5, 6 and a vertical frame rod 7 disposed between both end portions of the frame body. A pair of sheet extending metal fittings 9, 9 for extending the sheet 8 on the front surface of the frame body are fixed to the horizontal frame rods 1, 4 arranged on the upper and lower sides of the front side. Further, exterior plates 10 to 13 are attached to each surface except the front surface of the frame body.

[0003] The sheet extending metal fitting 9 comprises a metal fitting body 14 fixed to the horizontal frame rods 1 and 4 and a sheet gripping tool 15 for gripping the edge of the sheet 8. They are arranged upside down (FIGS. 14 and 15).

The metal fitting body 14 is a rod-shaped member having substantially the same length as the horizontal frame rods 1 to 4. On its front surface, guide pieces 14a 'and 14a "for guiding the sheet 8 are formed into a substantially V-shaped side surface. Also, on the rear surface, an L-shaped mounting piece 1 with a downward side surface.
4b is formed upright while maintaining a required interval. An accommodation groove 14c for accommodating the sheet gripping tool 15 is formed between the guide piece 14a "and the attachment piece 14b.

[0005] The sheet gripping device 15 is provided at the edge 8 of the sheet 8.
a winding member 16 formed with a winding groove 16a for winding a, and a peripheral portion 8a of the sheet 8 wound in the winding groove 16a between the winding member 16 and the inner wall of the winding groove 16a. The winding rods 17 are formed in the same length as the metal fitting body 14.

The winding member 16 is formed with a bent piece 16b protruding toward the rear side, and has an insertion hole 16c into which an adjustment bolt 18 is inserted. The screw body 14 has a screw hole 14d 'into which the adjustment bolt 18 can be screwed.
d is formed to protrude inward.

In order to attach the sheet 8 to the sheet mounting metal fitting 9, the edge 8a of the sheet 8 is inserted in a U-shape along the inner wall surface of the winding groove 16a of the winding member 16, and the U The winding groove 1 is formed in the peripheral portion 8a of the
The winding rod 17 is fitted from the side of 6a. Thereby, the edge 8a of the sheet 8 is fixed so as to be sandwiched between the winding rod 17 and the inner wall of the winding groove 16a.

When the adjusting bolt 18 is screwed into the screwing portion 14d, the winding member 16 moves the sheet 8 to the metal fitting body 14d.
The sheet 8 is moved to be immersed in the accommodating groove 14c while being pulled in, and the sheet 8 can be brought into a predetermined tension state by gradually applying a large tension to the sheet 8.

[0009]

However, in the above-mentioned conventional sheet mounting fitting, in order to mount the edge 8a of the sheet 8, the edge 8a of the sheet 8 is inserted into the winding groove 16a of the winding member 16. Must be inserted along the inner wall surface so as to form a U-shape so that the winding rod 17 can be inserted later. Therefore, the mounting operation is extremely troublesome and requires a long time. A long winding rod 17 is attached to the edge 8a of the U-shaped sheet 8 as described above.
Is also difficult to insert from the side of it.

As the adjustment bolt 18 is screwed into the threaded portion 14d, a larger tension can be gradually applied to the seat 8, and the seat 8 can be stretched. In other words, the amount of movement of the sheet gripper 15 and the tensile length of the sheet 8 are substantially equal.

For this purpose, a pair of sheet metal fittings 9, 9 are provided.
In the case where the sheet 8 which is merely stretched in the middle, in other words, if the sheet 8 before being tensioned by the adjusting bolt 18 has a large slack that is larger than the screwing amount of the adjusting bolt 18,
Only by adjusting the adjusting bolt 18, the slack cannot be completely corrected, and the seat 8 cannot be stretched in a tensioned state. Accordingly, it is necessary to stretch the sheet 8 with the slack amount as small as possible so that the slack can be corrected by the sheet tensioning fitting 9. It is extremely difficult to re-stretch the large slack of the sheet 8 inserted in the U-shape into the sheet 16a.

Further, even when the stretched sheet 8 is partially loosened, the winding rod 17 is once pulled out from the side of the winding member 16 and the edge 8a of the sheet 8 is removed. After adjusting the winding state of
7 needs to be reinserted. In other words, there is a disadvantage that the modification of the partially generated slack cannot be performed only in that part.

Accordingly, the present invention provides a sign board which can easily stretch a sheet in a short time and, even when the sheet is partially loosened, can easily correct the loosening. It is intended to provide a sheet stretching method.

As the winding member 37 moves down, the sheet 26 stretched between the guide piece 33a of the metal fitting body 33 and the winding member 37 is moved to the sheet pressing portion 37b of the winding member 37. With the winding portion 37a, the sheet 26 is pushed down on both sides of the sheet pulling piece 33d, and with this pushing down, the sheet 26 is pulled and tensioned between the two sheet metal fittings A, thereby loosening the sheet 26. It will be stretched without it. That is, when the sheet 26 is pushed down on both sides of the sheet pulling piece 33d, the sheet 26 can be pulled by a pulling amount almost twice as much as the amount of the downward movement of the winding member 37.

When the stretched sheet 26 is partially slackened, one or more winding members 37 disposed near the slackened portion are fixed by tension adjusting bolts 38 which are in contact with this. By adjusting the tension of the sheet 26 by lowering and shifting, partial slack can be corrected.

The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the invention. In the above description, one sheet pulling piece 33d is formed on the metal fitting body 33, and the sheet 26 is pulled down on both sides thereof by pressing down the sheet 26. However, two or more sheet pulling pieces are formed at required intervals. Then, the sheet may be pushed down on both sides of each of the sheet pulling pieces.

[0033]

According to the present invention, the sheet is pressed down and pulled on both sides of the sheet pulling piece of the metal fitting body by the winding portions of the plurality of winding members and the sheet pressing portion. Even if the sheet is greatly loosened, the slack can be easily corrected by slightly shifting each of the winding members, so that the sheet stretching operation can be performed in a short time.

Further, since only the wrapping member arranged near the portion where the slack is generated can be shifted independently from the other wrapping members, the sheet is partially slackened. In this case, the slack can be easily corrected.
