Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for stretching a curtain-like material such as a tent roof curtain or a partition wall curtain.

[0002]

[Prior art]

 FIG. 4 shows a conventional structure for tensioning a curtain-like object when a curtain-like object such as a tent roof or a partition wall curtain is attached.

Eyelet holes 2 are provided at a required pitch along the edge of the curtain 1, the rope 3 is passed through the eyelets 2, and the curtain 3 is sequentially wound around the force bone 4 such as a pipe. Had been concluded.

[0004]

[Problems to be solved by the device]

 In the conventional structure for stretching a curtain-shaped object, a large number of eyelet holes are punched in the curtain-shaped object 1, eyelets are struck, and a complicated work is required to hang a rope between the eyelets 2 and the force bones 4. In addition, the rope must be tightened uniformly in order to apply the required tension to the curtain 1 and prevent it from slackening, which requires a lot of labor and time.

In view of the above situation, the present invention intends to greatly improve the workability of tensioning the curtain-shaped material.

[0006]

[Means for Solving the Problems]

 According to the present invention, a fastening end thicker than the thickness of the curtain is formed at the end of the curtain, the fastening end is inserted into the carrying beam, and the curtain is fastened through the bolts engaged with the carrying beam. It is characterized by having done.

[0007]

[Action]

 By inserting the fastening end into the carrying beam, the curtain and the carrying beam are engaged with each other, and the bolt engaged with the carrying beam is fastened to the fixed side, and the bolt is tightened to fix the curtain end. Tightening can be performed and tension can be applied to the curtain.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 5 denotes a roof truss, and brackets 7 are provided on a lower side member 6 of the truss 5 at a required pitch. The bracket 7 is L-shaped, and a hole for bolt penetration is formed on the horizontal surface.

The edge of the curtain 1 is attached to a carrying beam 8 having the same length as the lower side member 6. The carrying beam 8 and the bracket 7 are tightened by bolts 9 and nuts 10, and by tightening the nuts 10, proper tension is applied to the curtain 1. The part where the bolt 9 projects from the nut 10 is cut off.

The engagement between the curtain 1 and the carrying beam 8 will be described with reference to FIGS. 2 and 3.

The edge portion of the curtain 1 is folded back and further fixed to form a tubular portion 11, and the core material 12 is inserted into the tubular portion 11. By inserting the core material 12, the tubular portion 11 is expanded and a fastening end 15 is formed.

The carrying beam 8 has an outer shape with a substantially rectangular cross section, and an engaging groove 13 having an inverted keyhole-shaped cross section with a circular lower portion is formed on the upper surface side and an inverted groove on the lower surface side. A convex fastening groove 14 is formed. The lower portion of the engaging groove 13 has a diameter larger than that of the tubular portion 11 into which the core material 12 is inserted, and the groove width of the upper portion is sufficiently wider than the thickness of the curtain 1. It is narrower than the fastening end 15. The groove width of the upper part of the fastening groove 14 is slightly wider than the dimension between the two parallel faces of the head of the bolt 9, and the lower part of the fastening groove 14 is slightly wider than the diameter of the screw part of the bolt 9.

When the curtain 1 and the supporting beam 8 are engaged with each other, the tubular portion 11 into which the core 12 is inserted is inserted into the engaging groove 13 from one end side of the supporting beam 8. . When the insertion of the tubular portion 11 is completed, the heads of the bolts 9 are inserted into the fastening grooves 14 of the carrying beam 8 by the number of the brackets 7. The bolt 9 is in a state in which the head portion is held in the fastening groove 14 and the screw portion hangs down, and is also movable in the longitudinal direction of the carrying beam 8. The bolt 9 is moved to align the bolt 9 and the bracket 7, and the bolt 9 is inserted into the bracket 7.

Tensioning is applied to the curtain 1 by screwing the nut 10 onto the bolt 9 and further tightening the nut 10. The threaded portion protruding from the nut 10 is cut off as appropriate.

Since tension is applied to the edge of the curtain 1 via the carrying beam 8, the tension is evenly applied, and the number of the bolts 9 is the same as that of the conventional eyelet holes 2. Significantly less than the number.

Incidentally, the engaging groove 13 can be appropriately changed in cross section such as a triangular shape, and the fastening groove 14 is formed along the longitudinal direction of the carrying beam 8. You may form the fastening groove 14 orthogonal to a longitudinal direction in the fitting position of. Further, the fastening end 15 may be formed by bending the edge of the curtain 1 several times, and the core 12 may be omitted, or if the curtain is made of synthetic resin such as a vinyl sheet, The fastening edge 15 may be formed by previously forming the edge to be thick. Furthermore, the carrying beam 8 is not set to have the length over the entire length of the edge of the curtain 1, but the carrying beams 8 cut to an appropriate length are inserted into the fastening ends 15 by the number of fastening points, and the carrying beam 8 is carried. The curtain 1 may be fastened with the bolt 9 via the beam 8.

[0018]

[Effect of device]

 As described above, according to the present invention, since it is only necessary to insert the fastening end of the curtain-shaped object into the carrying beam, there is no troublesome work such as passing a rope through a large number of eyelet holes, workability is good, and the curtain-shaped object is further improved. The operation of tightening the nut can also be done when tensioning the object, and it has the excellent effect that the labor of tightening the rope manually can be saved and the work time can be greatly shortened.
