Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a membrane repair jig used for repairing damaged parts of the membrane of an air tent.

(Prior art) The membrane body, which was sandwiched and fixed between the upper presser body and the lower presser body of the support frame of an air tent and had a downwardly convex shape, is reversed when air is applied, that is, the membrane is The body may become convex upward, and in this case, the membrane body sandwiched and fixed between the upper presser body and the lower presser body is adjacent to the side edge of the lower presser body and the side of the lower presser body. There were cases where it got caught between the edges and was damaged. Furthermore, when the air tent becomes concave due to snow, wind, or some other external pressure, a similar inversion occurs and the membrane may be damaged.

Therefore, it is necessary to repair the damaged membrane body, but if you try to repair the damaged area by airing down the air tent and removing the upper presser body,
After repair, there is a mark that will be aired up to restore the air tent, and when the air is lifted up, there is a risk that the membrane will be pinched between the side edges of the lower presser and the lower presser that are adjacent to each other, and be damaged again. Such a repair method was not desirable. For this reason, in the past, as shown in Fig. 4, after the repair, the air tent is aired down to the extent that the membrane body 1 does not flip due to air up, and a sheet 3 made of the same material is pasted on the repaired area 2. Repairs were being carried out.

(Problem to be solved by the invention) However, in this case, since the membrane body 1 was repaired without being removed from between the upper presser body 4 and the lower presser body 5, the upper presser body 4 and the lower presser body 5
There was a problem in that it was not possible to completely repair the part of the membrane body 1 that was sandwiched between the two.

As shown in FIGS. 1 to 3, first, a plurality of repair jigs are attached to the support portions 34 on the upper presser 32b, which is different from the upper presser 32a that fixes the membrane body requiring repair on the lower presser 33. to be fixed. A fitting bolt 44 having a hole that fits into the bolt 39 of the upper presser body 32b is fitted into the hole 38 formed at the bottom of the support portion 34, thereby fixing the support portion 34 on the upper presser body 32b. It is. Note that the membrane body 11
The number of repair jigs to be installed or the installation location of the repair jigs is determined according to the size of the repair spot 42 or the position of the repair spot 42.

Next, the support frame 3 near the repair location 42 of the membrane body 11
1. Remove the upper presser body 32a.

The membrane body 11 has an upper presser body 32a and a lower presser body 33 arranged at a predetermined interval on the support frame 31 of the membrane body 11.
It is fixed with a fixing bolt 39 between. This upper presser body 32a is removed.

Subsequently, the film body 11 is held between the holding parts 12.

To do this, first, the bag-shaped portion 3 near the end of the membrane body 11 is
0 is inserted between the clamping plates 13 so as to sandwich it from above and below, and the clamping bolts 16 are inserted into the bolt holes 14 provided in the clamping plates 13.
The clamping portion 12 is fixed to the rope 41 covered by the membrane body 11 through the rope 41 .

In this way, the hooking arm 18 of the winding section 17 is hooked onto the mounting bracket 15 of the clamping plate 13 which is fixed with the membrane body 11 sandwiched therebetween.

The traveling route of the connecting rope 19 connected to the hooking arm 18 is regulated by passing the connecting rope 19 through a rope guide 37 attached below the support part 34.

Furthermore, this connecting rope 19 is attached to the attachment hole of the protrusion 25 of the take-up roller 24 of the take-up device 20 attached above the support part 34.

It rotates in the opposite direction to gear 22.

As a result, the take-up roller 24 rotates, and the connecting rope 19 attached to the attachment hole of the protrusion 25 of the take-up roller 24 is wound in the direction of arrow B in FIG. 2.

When winding the connecting rope 19, the first gear 2
2 has a key-shaped stopper 23 on both ends thereof, so even if you accidentally release your hand from the take-up lever 24, the stopper 23 is attached to the first gear 22.
The key-shaped tips of the two mesh with each other, so that the first gear 22 does not rotate in the opposite direction, and the winding roller 24 that winds up the connecting rope 19 can be unwound by the tension of the membrane body 11. No connection rope 19
It is possible to wind up the material reliably and safely.

In this way, the sandwiching part 12 sandwiching the membrane body 11
is pulled by the winding device 20 of the winding section 17 supported by the support section 34, and the support frame 31
The drawn membrane body 11 is placed on the lower presser body 33, and is held and fixed between the upper presser bodies 32a.

Next, the holding part 12 that was holding the membrane body 11 is removed, and the supporting part 34 that was supporting the winding part 17 is passed through the fixing hole 35 formed at the bottom of the supporting part 34, and the fitting bolt 44 that was being fixed is removed. By removing it, it can be removed from above the upper presser body 32b. The membrane body is repaired in the manner described above.
