  Hereinafter, embodiments of the present invention will be described with reference to the drawings. This sheet stretched body is used for various purposes, but here, a case where it is used as a signboard installed outdoors is shown. Specifically, as shown in FIGS. 8 and 9, the sheet 2 is stretched on the inner peripheral side of a rectangular frame, and the front side of the sheet (the front side of FIG. 8, the left side of FIG. 9). Characters and designs for display purposes are drawn on the surface. In FIG. 8, the sheet 2 and a cover 8 to be described later are shown through. The frame body is configured by a four-round frame of the attachment material 1, and each attachment material 1 is formed by joining two L-shaped angles by welding as shown in FIG. It has a front expected surface 11 that extends toward the front side, and a rear expected surface 12 that is located on the outer peripheral side of the front expected surface 11 and extends toward the rear side.

  And as shown in FIG.1 and FIG.2, the sheet | seat 2 is attached with respect to this attachment material 1 with the tension | tensile_strength tool 3 and the holder 4. As shown in FIG. In FIG. 2, the sheet 2 and a cover 8 described later are shown in a transparent manner. As shown in FIG. 8, the tension tool 3 and the holding tool 4 are attached side by side at predetermined intervals along the longitudinal direction of each attachment material 1. The tensioning tool 3 is attached to the attachment material 1, the holding tool 4 holds the end portion of the sheet 2, and the tensioning tool 3 pulls the holding tool 4 toward the outer peripheral side (attachment material 1 side), whereby the sheet 2 Is stretched.

  As shown in FIG. 3, the tension tool 3 includes a shaft portion 33 extending in the inner and outer peripheral directions, and a longitudinal direction of the attachment member 1 attached to an inner peripheral side end (an end opposite to the attachment member 1) of the shaft portion 33. It has a hooked portion 31 extending in the left-right direction in FIGS. 2 and 3B, and is generally T-shaped as a whole. As for the shaft part 33, about 2/3 on the outer peripheral side of the entire length is a screw part 34 forming a screw thread, and about 1/3 on the inner peripheral side is a flat plate part 35. . On the other hand, the hooked portion 31 is a member having a substantially U-shaped cross section that opens toward the inner peripheral side, and the outer peripheral side surface is formed in a substantially arc shape that is convex toward the outer peripheral side. Further, a hole 36 is formed on the outer peripheral side surface of the hooked portion 31, and the inner peripheral side end portion of the flat plate portion 35 is inserted into the hole 36 and is pivotally supported from the front-rear direction. Therefore, the hooked portion 31 can be rotated around the axis in the front-rear direction with respect to the shaft portion 33 by the clearance of the hole 36 and the flat plate portion 35. Further, a biasing member 32 made of a spring is extrapolated to the screw portion 34 of the shaft portion 33, and the inner peripheral side end portion of the biasing member 32 is fixed to the inner peripheral side end portion of the screw portion 34. is there. And the tension tool 3 configured in this way is inserted into the hole formed in the front side expected surface 11 of the mounting material 1 from the inner peripheral side, and the nut 37 is screwed onto the screw part 34 from the outer peripheral side and attached. By rotating the nut 37, the shaft portion 33 and the hooked portion 31 move in the inner and outer peripheral directions. The outer peripheral side end portion of the urging member 32 abuts on the inner peripheral side surface of the front expected surface 11 of the attachment material 1, and the shaft portion 33 and the hooked portion 31 are arranged on the inner peripheral side with respect to the attachment material 1 (the holder 4 Side).

  Further, as shown in FIG. 4, the holder 4 includes a hook portion 41 located on the outer peripheral side (attachment material 1 side), a holding portion 42 located on the inner peripheral side (opposite side of the attachment material 1), The front side wall 43 is connected. The hook portion 41 is formed from the outer peripheral side end portion of the front side wall 43 toward the rear outer peripheral direction, and has a substantially semicircular arc shape convex toward the outer peripheral side, as shown in FIG. The size is such that the hooked portion 31 of the pulling tool 3 is accommodated inside. And the hook part 41 and the front side wall 43 are formed with a notch 44 at the center in the longitudinal direction of the mounting material 1 (left and right in FIGS. 2 and 4B), and are divided into left and right. . As shown in FIG. 2, the hook portion 41 is hooked on the hooked portion 31 of the tension tool 3 from the front side so that the shaft portion 33 of the tension tool 3 is inserted into the notch 44. In this state, the holder 4 is pulled to the outer peripheral side by rotating the nut 37 of the pulling tool 3 to move the shaft portion 33 and the hooked portion 31 to the outer peripheral side.

  The holding portion 42 includes a receiving portion 5 formed from the inner peripheral side end portion of the front side finding wall 43 toward the rear inner peripheral direction, and a separate pressing member 6. The receiving part 5 has a recess 51 that opens toward the front side, and the width of the opening is such that the presser 6 can pass through, and the inner space of the recess 51 is larger than the presser 6, The presser 6 can be inserted. The recess 51 has a front abutment wall 53 extending from the inner peripheral side end portion of the front finding wall 43 toward the inner peripheral side, and an expectation extending from the inner peripheral side end portion of the front finding wall 43 toward the rear side. A wall 56, a rear finding wall 57 extending from the rear end of the prospective wall 56 toward the inner peripheral side, and a guide extending from the inner peripheral end of the rear finding wall 57 toward the front inner peripheral direction. The inclined wall 55, the rear contact wall 54 extending from the inner peripheral side end portion of the guide inclined wall 55 toward the inner peripheral side, and the side extending from the inner peripheral side end portion of the rear contact wall 54 toward the front side. It is formed by the side abutment wall 52 and opens from between the front abutment wall 53 and the side abutment wall 52. Note that the inner peripheral side end of the guide oblique wall 55 is positioned on the inner peripheral side with respect to the inner peripheral end of the front contact wall 53. In addition, a triangular wave-shaped concavo-convex portion 58 is provided on the inner side surfaces of the side contact wall 52, the front contact wall 53, and the rear contact wall 54 (the surface on the inner space side of the recess 51). Furthermore, a screw hole 59 for attaching a pressing tool 7 to be described later is formed in the center of the rear side wall 57 in the longitudinal direction of the attachment member 1 (left and right direction in FIGS. 2 and 4B). is there. On the other hand, as shown in FIGS. 1 and 2, the presser 6 is a rod-shaped member having a rectangular cross section extending along the longitudinal direction of the mounting material 1 (left-right direction in FIG. 2). Is about three times as long. A triangular wave-shaped uneven portion 61 is provided on the surface, which meshes with the uneven portion 58 of the receiving portion 5. As shown in FIG. 8, the pressing tools 6 are arranged so as to be substantially continuous with adjacent pressing tools 6 with a narrow gap, and a plurality of tensioning tools 3 with respect to the attachment material 1 are matched to the arrangement position of the pressing tools 6. And the mounting positions of the plurality of holders 4 with respect to the seat 2 are determined.

  As shown in FIG. 1, the end of the sheet 2 is wound around the presser 6 from the front side, and the presser 6 is inserted into the recess 51 of the receiving unit 5 together with the sheet 2. In the state where the sheet 2 is wound, the inner peripheral side surface (side surface) abuts the side contact wall 52 with the sheet 2 sandwiched between the presser 6 and the front side surface sandwiches the sheet 2 with the front contact wall 53. The rear side comes into contact with the rear side contact wall 54 with the sheet 2 interposed therebetween. In this way, by holding the sheet 2 between the presser 6 and the inner surface (the side contact wall 52, the front contact wall 53, and the rear contact wall 54) of the recess 51, the holding unit 42 is sandwiched. Holds the sheet 2, and in particular, the uneven portion 61 of the presser 6 and the uneven portion 58 of the recessed portion 51 mesh with each other and bite into the sheet 2, so that the sheet 2 is more firmly held.

  Further, as shown in FIGS. 1 and 9, a cover 8 having a substantially L-shaped cross section is attached to the peripheral portion of the seat tension member. The cover 8 is fixed to the rear expected surface 12 of the attachment material 1, and covers the attachment material 1, the tension tool 3, and the holding tool 4 when the sheet stretched body is viewed from the front, and only the sheet 2 is visible. It is like that.

  The configuration of each part such as the tension tool 3 and the holding tool 4 is as described above, and subsequently, a construction procedure when the sheet 2 is stretched by these will be described. First, the end of the sheet 2 is wound around the presser 6, and the presser 6 is inserted together with the sheet 2 from the opening of the recess 51 of the receiving part 5. At this time, as shown in FIG. 5A, the presser 6 can be inserted along the guide inclined wall 55 from the front inner circumferential direction. This is because the inner peripheral side end portion of the guide inclined wall 55 is located on the inner peripheral side with respect to the inner peripheral side end portion of the front contact wall 53, and the inner side surface of the guide inclined wall 55 (the inner space of the recess 51). This is because the distance between the side surface) and the inner peripheral end of the front contact wall 53 is wider than the short side width of the cross section of the presser 6. In addition, since the unevenness | corrugation part 61 of the pressing tool 6 is not caught in the inner surface of the guide inclined wall 55, the pressing tool 6 is guided to insertion by the guide inclined wall 55, and is smooth. Can be inserted. Next, as shown in FIG. 5B, the presser 6 inserted into the recess 51 is rotated so that the outer peripheral side portion is directed to the front side and the inner peripheral side portion is directed to the rear side. As a result, the pressing member 6 has the front side surface, the rear side surface, and the inner peripheral side surface in contact with the front side contact wall 53, the rear side contact wall 54, and the side contact wall 52, and The holding part 42 holds the sheet 2. And even if only this, the uneven | corrugated | grooved part 61 of the pressing tool 6 and the uneven | corrugated | grooved part 58 of the recessed part 51 mutually mesh | engage and bite into the sheet | seat 2, Therefore Although the sheet | seat 2 is hold | maintained firmly, The pressing tool 7 made of a screw is screwed into the screw hole 59 of the rear side wall 57 from the rear side. The pressing tool 7 abuts against the pressing tool 6 from the rear side and presses against the front-side contact wall 53 to sandwich the sheet 2 more firmly, and prevents the pressing tool 6 from rotating in the reverse direction. Hold on. The steps up to this point are repeated, and the holder 4 is attached over the entire circumference of the sheet 2 so that the pressers 6 are arranged substantially continuously. Next, the tension tool 3 is inserted from the inner peripheral side into each of the holes formed in the front side expected surface 11 of the mounting material 1 along the longitudinal direction, and the nut 37 is screwed to the screw portion 34 from the outer peripheral side. And attach. At this time, the urging member 32 is pressed and contracted by tightening the nut 37 so that the outer peripheral side end of the urging member 32 contacts the inner peripheral side surface of the front expected surface 11. The portion 33 and the hooked portion 31 are biased toward the inner peripheral side. Next, the hooking portion 41 of the holding tool 4 holding the sheet 2 by the holding portion 42 is hooked on the hooked portion 31 of the pulling tool 3. At this time, the hook portion 41 is hooked on the hooked portion 31 from the front side so that the shaft portion 33 of the pulling tool 3 is inserted into the notch portion 44, and the hooked portion 31 is placed inside the hooking portion 41. Since the hooking portion 41 has a substantially arc shape, as shown in FIG. 6, the hooking portion 41 is rotatable about the longitudinal axis of the mounting member 1 with respect to the hooked portion 31 and receives the hooking portion 41. Since the outer peripheral side surface of the hook portion 31 is also substantially arc-shaped, the hook portion 41 rotates smoothly. Therefore, as shown in FIG. 7A, the holder 4 can be moved from an arbitrary angle while maintaining the posture of the tension tool 3 in which the shaft portion 33 is perpendicular to the front expected surface 11 of the mounting material 1 (see FIG. Then, it can be hooked (from the front inner circumferential direction). Further, even after the hooking, the holding tool 4 rotates around the longitudinal axis of the attachment member 1 with respect to the pulling tool 3 in a state where the hooking part 41 of the holding tool 4 is hooked on the hooked part 31 of the pulling tool 3. Since the holder 4 can freely follow the direction of the sheet 2 while maintaining the posture of the tension tool 3, the holder 4 can be hooked on the tension tool 3 in order. Smooth movement is possible without hindering the movement of the finished part. And if the hook part 41 of all the holders 4 is hooked on the to-be-hooked part 31 of the tension tool 3, as shown in FIG.7 (b), the nut 37 of each tension tool 3 will be tightened. Then, the shaft portion 33 and the hooked portion 31 move to the outer peripheral side, and the holder 4 is pulled to the outer peripheral side, and is in a direction parallel to the shaft portion 33 as shown in FIG. When the nut 37 is further tightened, the sheet 2 is also pulled from the periphery to the outer peripheral side as the holder 4 is pulled to the outer peripheral side, and is stretched without bending as shown in FIG. Finally, the cover 8 is attached to the attachment material 1 to cover the attachment material 1, the tension tool 3 and the holding tool 4.

  According to the sheet stretched body thus configured, the hooking portion 41 of the holding tool 4 holding the sheet 2 is hooked on the hooked portion 31 of the pulling tool 3, and the holding tool 4 is moved to the outer peripheral side by the pulling tool 3. By pulling, the sheet 2 can be stretched. And since the to-be-hooked part 31 of the tension | pulling tool 3 always protrudes from the attachment material 1 and is located in the inner peripheral side by the urging member 32, it is easy to hook the hooking part 41 of the holder 4. When the urging member 32 is not provided, the hooked portion 31 is retracted to the attachment material 1 side particularly at the lower side and the vertical side of the sheet stretched body, and the hooked portion 31 is hooked when the hooking portion 41 of the holder 4 is hooked. However, in the present invention, construction is easy without requiring such labor. Further, the urging member 32 also functions as a stopper for loosening the nut 37 that fixes the tension tool 3 to the attachment member 1. In addition, when the sheet 2 is held by the holding tool 4, it is only necessary to insert the pressing tool 6 into the concave portion 51, so that the construction is also easy in this respect. At this time, the inner peripheral side end portion of the guide inclined wall 55 of the receiving portion 5 is located on the inner peripheral side with respect to the inner peripheral side end portion of the front contact wall 53, and the inner side surface of the guide inclined wall 55; Since the distance between the front contact wall 53 and the inner peripheral side end is wider than the short side width of the cross section of the presser 6, the presser 6 can be inserted from the front inner peripheral direction. Since the insertion of the tool 6 is guided by the guide slant wall 55 and can be smoothly inserted, it is easy to mount the tool 6 even in the case of the large sheet 2. In particular, since the uneven portion 61 of the presser 6 and the uneven portion 58 of the recessed portion 51 mesh with each other and bite into the sheet 2, the sheet 2 is held more firmly. Furthermore, the pressing tool 6 is pressed by the pressing tool 7, and the sheet 2 is more firmly sandwiched, and the pressing tool 6 is prevented from rotating in the reverse direction, thereby reliably holding the sheet 2. In addition, even if it is a case where the sheet | seat 2 is wound around the holding | suppressing tool 6 not from the front side but from the back side, since it hold | maintains similarly, even if there is a mistake in a construction procedure, the sheet | seat 2 does not come off. In addition, since the hooking portion 41 of the holder 4 is substantially arc-shaped, the hook portion 31 is pivotably hooked on the hooked portion 31 of the pulling tool 3, so that the shaft portion 33 is attached to the front expected surface 11 of the mounting material 1. The holding tool 4 can be hooked from an arbitrary angle while maintaining the posture of the pulling tool 3 which is perpendicular to it, and follows the direction of the sheet 2 while keeping the posture of the pulling tool 3 even after being hooked. Since the holder 4 rotates freely, smooth tensioning is possible, and construction is also easy in this respect.

  The present invention is not limited to the above embodiment. For example, the sheet stretched body can be used as a partition or a tent in addition to a signboard. In addition, for the part where the holding part holds the sheet, it is only necessary that the pressing tool around which the sheet is wound is finally inserted into the recess, and as a construction procedure, the sheet is wound around the pressing tool and then inserted into the recess. Alternatively, the pressing tool may be inserted after inserting only the sheet into the recess.
