Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention bends an elastic flexible tent pole made of metal or synthetic resin into a semicircular arc shape, and uses the tension to tension it. The present invention relates to a support structure for a protector with a cushion that is attached to the tent pole when a hollow joint pole is used as the tent pole.

(Prior art) The inventor of this application previously published a utility model application in 1972.
-Devised a tent pole protector with a cushion, which is shown in No. 31530. The above idea is based on the idea that a hole 3 with an upper opening is formed in the protector main body 1 as shown in FIGS. is mounted, and the joint 6 provided on the lower peripheral edge of the cap nut-shaped portion 5 is screwed and fixed to the joint 6 provided near the upper edge of the protector main body 1, and the through hole at the top of the cap nut-shaped portion 5 is fixed. This is a tent pole protector with a cushion which prevents a flexible tent pole from coming off.

When the above-mentioned known protector is used for an integrally formed flexible tent pole that is not a jointed pole, the tent pole 8 can be attached to the tent 10 by its tension.
It buffers the sharp pushing force by turning the corners outward,
This has the ideal effect of constantly maintaining appropriate tension depending on the situation through cushioning action, and maintaining adaptability to the tension of the tent poles without damaging the fabric of the tent body. However, it was not necessarily suitable as a protector with a cushion to be attached to a tent pole.
The reason for this is that a joint tent pole has a joint pipe 12 that can be inserted into one of the hollow pipe bodies, and connects the joint poles one after another to form a hollow joint tent pole. Each joint pole unit 11a, 11b, 11c that constitutes the tent pole 11...
Although it is necessary to penetrate the elastic body through each joint pole unit so that the elastic bodies are in close contact with each other, and to fix both ends of the elastic body to the protector, the known protector is not provided with such fixing means; In the case of joint tent poles, the intermediate joint pole itself may occasionally break, so it is required that the joint pole itself can be easily replaced.

(Problem to be solved by the invention) The present invention can fix the extendable body that penetrates the inside of the tent pole to the protectors located at both ends of the hollow tent pole, and therefore presses each tent pole alone. It can be used as a single joint pole when tightly fitted, and if the intermediate joint pole itself is damaged, it can be easily replaced, and like the above-mentioned known protector, the tension of the tent pole It buffers the force that sharply pushes the corners of the tent outward, and the cushioning action allows the tent to always maintain appropriate tension depending on the situation, allowing the fabric of the tent body to adapt to the tension of the tent poles without damaging it. It is an object of the present invention to provide a support structure for a hollow tent pole using a protector with a cushion.

[Structure of the idea]

(Means for Solving the Problems) In order to achieve the above object, the present invention forms a hollow joint tent pole insertion opening on the top surface of the hollow cylindrical protector body, and attaches a stone protrusion removably to the bottom surface. The upper surface of the stone protrusion elastically supports the rear end of the hollow tent pole via a spring, and the upper surface of the stone protrusion has a mounting rod for attaching the elastic body protruding into the protector body. This tent has a structure in which a hollow tent pole is supported by a protector with a cushion.

(Embodiment) The above configuration of the embodiment shown in the drawings will be explained as follows.

A hollow cylindrical protector main body 21 is made of a material such as metal or hard synthetic resin, and an inwardly bent flange 21a is formed on the top surface of the protector body 21, so that an insertion opening for the hollow tent pole 11 is formed on the top surface. 2
form 2. Male screw plate 2 with a stone protrusion 25 protruding downward from the lower opening 23 of the protector main body 21
A mounting rod 26 is integrated with the male threaded plate 24, into which the threaded portions 24' of 4 are screwed together, and a hole 26' is provided in the center of the upper surface of the male threaded plate 24 for attaching a stretchable elastic body 29 such as a rubber cord or coiled metal wire. When the male threaded plate 24 is screwed into the female threaded part 21' provided inside the lower opening of the protector main body 21, the mounting rod 26
is located within the protector main body 21. Further, the stone protrusion 25 may be formed to have a small diameter as shown in FIGS. 2 and 3, or may be formed in a hemispherical shape as shown in FIG. 4. Protector body 21
A coiled spring 27 is placed on the male threaded plate 24 inside, surrounding the mounting rod 25. Reference numeral 28 denotes an outer pipe for a stopper that is tightly fitted and fixed to the portion of the hollow tent pole 11 inserted into the protector body 21 of the tent pole 11a to prevent the pole 11a from coming off the insertion opening 22. be.

The hollow joint tent pole 11 according to the present invention includes a plurality of joint pole single bodies 11a each having a joint pipe 12 fixed and protruding from one opening of a hollow pipe.
By inserting the joint pipe 12 of 11b... into the other opening of another joint pole unit, a continuous tent joint pole 11 is constructed, and each joint pole unit at both ends is connected to the protector of the present invention. The tent poles are inserted irremovably through the tent pole insertion openings 22, 22, and are resiliently stopped by the coiled springs 27. Further, both ends of the elastic body 29 passed through the hollow portion of the hollow tent pole 11 are tied to the holes 26', 26' of the attachment bodies 26, 26 in the protector at both ends, respectively. In this way, the hollow tent pole 11 is configured such that the protectors with cushions are attached to both ends thereof, and each of the tent poles constituting the tent pole 11 is tightly fitted and compressed. 10 is a tent.

〔effect〕

The present invention fixes both ends of a stretchable elastic body that passes through a hollow tent pole in a protector with a cushion fixed to both ends of the tent pole, and the poles that make up the tent pole loosen and come off. If the tent pole itself is damaged, the male threaded plate 24 can be removed as shown in Figure 3, and it can be quickly replaced with another intermediate pole. The force that sharply pushes the corners of the tent outward is buffered by the buffering force of the coil spring 27, and its cushioning action always maintains an appropriate tension depending on the situation, without damaging the fabric of the tent body. It is possible to obtain a support structure for hollow tent poles with a cushioned protector that can adapt to the tension of the tent poles.
