DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet fastening structure.

[0002]

2. Description of the Related Art Conventionally, as a structure for fastening a cloth sheet such as a tent to a bar material such as a pillar, for example, as shown in FIG. Attached to the rod P, wound around the hole T 'near the edge of the mounting cloth T, passing each of the binding straps R once, and then pulling both ends of the binding strap R in the direction of the arrow. By
The mounting cloth T is wound around the bar P in a tensioned state, and both ends are brought together to perform binding such as solid knotting as shown in FIG. 6 (B).

[0003]

However, in the conventional fastening means using the binding strap R, both ends of the binding strap R are pulled in the direction of the arrow, and the mounting cloth T is wound around the bar P in a tensioned state. Further, when the ends are entangled and bound, it becomes difficult for the mounting cloth T to try to suppress the reaction force that tends to return from the above-mentioned tension state.
Eventually, there is a possibility that the unity may be loose. In addition, since the binding by the string is due to the pinching (squeezing) due to the winding of the string, since looseness is not regulated structurally,
There were problems such as looseness and loosening of unity.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a sheet fastening structure capable of securely and securely fastening a sheet without fear of loosening or loosening. Is to provide.

[0005]

According to the sheet fastening structure of the present invention, one end of a tape having a large number of openings at appropriate intervals in the longitudinal direction is attached to a cloth sheet and wound around a bar. It is inserted into the long hole of one side edge of the mounting cloth, folded back and overlapped, and a boss protruding from the body flange of the fastener is inserted into the opening of the tape end of the overlapped portion. Then, a fastening ring is fitted into the boss portion, and the overlapping portion of the tape is sandwiched between the boss portion and the main body flange portion, while the other end of the tape is attached to the other side edge portion of the mounting cloth. Insert it into the long hole and turn it back, overlap it on the outside of the tape at the one end, squeeze it, wind the mounting cloth tightly around the bar, and keep this state, The boss is further inserted into the opening as appropriate, and It fitted another fastening ring part, characterized in that clamped tape between the fastening ring.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, A is a ladder tape, B is a fastening device, and shows a state in which the cloth sheet S is fastened to the pillar P by these. More specifically, the ladder tape A is folded back through the slit-shaped elongated hole T ″ formed in the mounting cloth T of the cloth sheet S, and the ladder tape A is overlapped in a state where the ladder tape A is narrowed in the folding direction. Is fastened by a fastening tool B.

As is apparent from FIG. 2, the ladder tape A is formed by bridging two strip portions A 'having a predetermined width and an appropriate interval between these two strip portions A'. ,
A fibrous structure composed of cross-linked portions A ″ forming openings a therebetween, and is woven so as to be highly flexible and to have sufficient strength particularly against tensile force in the longitudinal direction. I have.

As shown in FIG. 3, the fastening device B includes a boss B2 integrally projecting from the center of a disk-shaped main body flange B1 and a peripheral edge of the main body flange B1. And elongated connecting portions B3 'and B4' are respectively extended from opposite sides thereof, and fastening rings B3 and B4 are integrally provided at the ends thereof.

The boss portion B2 has a two-stage flange-shaped locking portion B
2 ′ and B2 ″.
Locking pieces B3 "and B4" are formed at the center of the pieces B4 and B4. The fastener B is integrally formed of a synthetic resin. In particular, the connecting portions B3 'and B4' have flexibility, and the locking pieces B3 "and B4" have rigid elasticity.

As shown in FIG. 3, a boss B2 of the fastener B is formed in an opening a near one end of the ladder tape A.
4, as shown in FIG. 4, the one end of the ladder tape A is passed through the slit-shaped long hole T ″ of the mounting cloth T, and then bent. The fastener B3 is fitted into the boss B2 by passing the boss B2 of the fastener B through the opening a, and the locking piece B3 ″ of the fastening ring B3 is engaged with the flange-shaped locking part B2 ″ of the boss B2. Fix it in a state where it is locked.

Next, the other side of the ladder tape A is passed through an elongated hole T ″ on the other side of the mounting cloth T (see FIG. 4), and the ladder tape A is folded back to form In a state where the ladder tape A is overlapped and squeezed out, the boss B2 of the fastening tool B is inserted into the opening a at the other end of the ladder tape A, as shown in FIG. As described above, the other retaining ring B4 is fitted and the locking piece B of the retaining ring B4 is fitted.
4 "is fixed in a state of being locked to the flange-shaped locking portion B2 'of the boss portion B2. When the boss portion B2 is passed through the opening a of the ladder tape A, as shown in the drawing, It is preferable that the end of A is folded back from the viewpoint of strength in terms of erroneous release of binding to the tape due to an external force.Since the ladder tape A of the present embodiment has the bridge portion A ″, the boss portion B2 Structural loosening is controlled by contact with the unit, so that the unity is not loosened. In view of the above, the structure of the present invention is particularly suitable for a part where strength is required, such as a tent, and in which an unexpected external force may be generated from the surroundings. It does not give fear of the tent collapse.

[0012]

According to the present invention, one end of a tape having a number of openings formed at appropriate intervals in the longitudinal direction is inserted into a long hole of one side edge of a mounting cloth attached to a cloth sheet and wound around a bar. A boss protruding from the main body flange of the fastening device is inserted into the opening of the tape end portion of the overlapped portion, and a fastening ring is fitted into the boss portion. The overlapped portion of the tape is sandwiched between the main body flange portion and the other end of the tape is inserted into the elongated hole of the other side edge of the mounting cloth and folded back to form a tape at the one end. The mounting cloth is wound around the bar in a tightened state while being squeezed and overlapped on the outside of the tape. Insert another fastening ring into the boss,
Since the tape is sandwiched between the stopper ring and the fixing ring, the following effects can be obtained. (1) A structure capable of fitting the boss and the opening while maintaining the tensioned state. (2) In order to release the binding, an operation of applying a force upward from between the tape and the fixing ring is required, so that there is no possibility that the binding is unintentionally released by an unintended force from the outside. (3) Since the tape has an appropriate width and is attached to the bar by surface contact, the holding of the bar is stabilized, and the number of binding portions can be reduced. (4) Since a plurality of fastening rings are provided, the tape can always be attached to the cloth piece, and the work of attaching to the bar can be reduced.
