Description

  The present invention relates to a sign sheet mounting apparatus and method.

  Resin sheets printed by inkjet or the like have been used on the surface of outdoor signboards or internally illuminated signboards. In order to attach the printed resin sheet to the frame, it is necessary to fix it while pulling uniformly around it, but there is no simple equipment and tools for that purpose, and large-scale tools and complex frames are used. Was. This was one of the factors that hindered the spread of sheet signboards.

  The present invention has been made in view of this problem, and an object of the present invention is to provide an apparatus and a method for fixing a sheet to a frame while pulling the periphery of the sheet uniformly.

The sign mounting device for a signboard of the present invention that achieves the above object,
(A) a pedestal attached to the frame of the signboard;
(B) a stopper removably attached to the pedestal;
(C) a tension bar which has a bar body which can slide through the opening of the stopper and which is given a tensile force by an elastic body;
(D) It is characterized by comprising a frame in which one end can be engaged with the bar body and the other end is a receiving portion capable of receiving the sheet end portion.

The signboard sheet mounting method of the present invention comprises:
(A) The process of attaching a base to the frame of a signboard.
(B) A step of inserting the thickened sheet end into the receiving part of the frame.
(C) A step of attaching a stopper and a tension bar to the pedestal.
(D) A step of joining the frame and the tension bar and pulling the entire surface uniformly.
(E) A step of fixing the frame to the pedestal when it is stretched sufficiently uniformly.
(F) A step of removing the stopper and the tension bar.
It is characterized by having. The order of each process may be changed.

  According to the apparatus and the method of the present invention, the resin sheet can be stretched with appropriate tension by using only a general tool for each component itself.

  The pedestal is preferably separate from the signboard frame as in the examples described later, but when the frame is thick and firm, it can be used as a pedestal.

  Any stopper may be used as long as it has a through hole for inserting a tension bar. For example, it can be set as the board | plate material which has a U-shaped opening.

  The tension bar may be composed of, for example, an elongated bar body, an intermediate moving member that can slide by a spring force, and an adjustment screw.

  One end of the frame is engageable with the bar body, and the other end is a receiving portion that can receive the sheet end. The engagement with the bar body can be, for example, an engagement between both hooks. The reception of the sheet end can be, for example, a combination of a sheet end having a thick diameter and a receiving unit that receives the sheet end.

In order to increase the diameter of the sheet edge, there is the following method.
(a) Fold the end of the sheet and insert a core material (round bar) at the crease. The doubled sheet fabrics that are folded back are joined with an adhesive or stitched together.
(b) A tape having a thick tip in advance is joined to the end of the sheet with an adhesive or is sewn together.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of an apparatus according to an embodiment of the present invention, and FIG. 2 is a side view.

  As shown in FIG. 2, a case where a printed resin sheet is stretched on the upper surface of an outdoor signboard or an internally illuminated signboard is illustrated.

  First, a base 2 having an L-shaped cross section is attached to a frame 1 of an outdoor signboard or an internally illuminated signboard. A “U” -shaped engaging portion 21 is formed on the outer side of the base 2, and the stopper 3 can be attached thereto. As shown in FIGS. 1 and 5, the stopper 3 has a plate shape, but is provided with a U-shaped opening 31 at the top. This U-shaped opening protrudes upward from the base 2.

  A tension bar 4 is attached so as to penetrate the U-shaped opening 31 of the stopper. The tension bar 4 has an elongated bar body 41 as shown in FIG. An intermediate moving member 42 slidable by a spring force is attached to the bar body 41. The spring 43 is set between the intermediate moving member 42 and the adjusting screw 44 at the rear end, and the tensile force can be adjusted by adjusting the position of the adjusting screw 44. The forward movement of the intermediate moving member 42 is limited by the stopper 3 (that is, the peripheral plate material of the U-shaped opening 31). A first hook 45 is provided at the forefront of the bar main body 41 and can be engaged with a rear end of the frame 5 described below.

  As shown in FIGS. 1 and 4, the frame 5 has an elongated body 51. A second hook 52 with which the first hook 45 is engaged is formed at the rear end of the main body 51, and a cylindrical receiving portion 53 having a cutout 54 in the longitudinal direction is formed at the front end.

  The end portion 61 of the sheet 6 is fixed to the receiving portion 53, but the sheet end portion 61 needs to be processed in advance before being fixed to the receiving portion 53. For example, the method is shown in FIGS. 4A and 4B.

  In the method of FIG. 4B, the sheet end portion 61 is folded back, and a core material (round bar) 62 is inserted at the crease. The doubled sheet fabrics that are folded back are joined with an adhesive or stitched together.

  In the method shown in FIG. 4 (c), the tape 63 having a thick tip formed in advance is joined to the end of the sheet with an adhesive or stitched as it is.

  The distance of the notch 54 of the receiving portion 53 is usually slightly shorter than the thickness of the sheet end portion 61. There are the following two methods for inserting the sheet end portion thus formed into the receiving portion. The first is a method in which the front surface of the sheet end portion 61 is strongly pushed into the front surface of the receiving portion 53. For example, it is a method in which a round bar is strongly pushed into a cut with respect to a tube having a cut in the longitudinal direction. The second is a method in which both side end portions are engaged with each other and are stacked in the longitudinal direction as they are. For example, it is like putting a round bar in a tube.

  In the above description, the sheet setting method is already clear, but it can be summarized as follows according to the work procedure.

(1) Insert the thick sheet end 61 into the receiving part 53 of the frame.
(2) A base 2, a stopper 3, and a tension bar 4 are attached to the frame 1 of an outdoor signboard or an internally illuminated signboard.
(3) Join the frame 5 and the tension bar 4 and pull the entire surface uniformly.
(4) The frame 5 is fixed to the pedestal 2 with screws 55 and nails when it is stretched sufficiently evenly.
(5) Remove the stopper 3 and the tension bar 4.

  In FIG. 2, both ends of the sheet are fixed using the apparatus of the present invention, but only one end (for example, the left end in FIG. 2) may be used. This is because the other end (right end in FIG. 2) is fixed from the beginning and adjustment can be performed at the left end.

  By the above operation, the resin sheet can be stretched on the frame of the outdoor signboard or the internally illuminated signboard with moderate tension.
