Description

  The present invention relates to a sheet pressing device for an agricultural and horticultural house, and more particularly, to a sheet pressing device used to prevent a shape of a sheet retained by a framework of an agricultural and horticultural house from being deformed.

  As schematically shown in FIG. 7, an agricultural and horticultural house is made by stretching a sheet 2 such as a vinyl chloride resin sheet on a framework 1 assembled in a predetermined shape. In such an agricultural and horticultural house, the sheet pressing device 3 is used to prevent the sheet 2 from fluttering or losing shape due to being blown by the wind. The sheet pressing device 3 includes a band 4 such as a string or a rope stretched on the sheet 2 so as to surround a portion extending from the upper part to the side part of the sheet 2, and a number of anchors positioned outside the lower end of the sheet 2. And a connecting rod 6 made of a metal shaft or pipe supported by 5, and by binding the end of the band 4 to the connecting rod 6, a predetermined tension is applied to the band 4 to the connecting rod 6. It is connected. In FIG. 7, reference numeral 7 denotes a knot formed by binding the band 4 to the connecting rod 6.

  In the agricultural and horticultural house, it is impossible to avoid spontaneous loosening of the band 4 over time. Therefore, when the band 4 is loosened, the tension recovery operation of the band 4 is performed. However, in this tension recovery operation, after the knot 7 of the band 4 to the connecting rod 6 is released, the band 4 is pulled to apply a predetermined tension, and the band 4 is attached to the connecting rod 6 while maintaining this tension. It is a troublesome thing to bind and form the knot 7.

  Therefore, the applicant of the present application connects the band-shaped band 4 to the connecting rod 6 and holds the end of the band-shaped band 4 using a clamper described later, thereby simplifying the tension recovery operation, There is provided a sheet pressing device for an agricultural and horticultural house capable of suppressing spontaneous loosening of the band 4 (see Patent Document 1).

  As shown in FIG. 8, the sheet pressing device 3 described in Patent Document 1 includes a band-like band 4, a connecting rod 6 such as a metal shaft or pipe, and a clamper 8, and the clamper 8 has a rectangular shape 2. Two ring bodies 9 and 10 are connected by a ring 11 so as to be slidable in an overlapping state. And the ring part 15 connected with the connecting rod 6 was formed in the three openings 12, 13, and 14 formed by sliding the two ring bodies 9 and 10 and shifting them in a loop shape. When the two-layer overlapping portion 16 of the band 4 is meandered and slidably inserted, when the end of the band 4 is pulled upward to apply tension to the band 4, the band 4 is inserted into the three openings 12, 13, and 14. The two overlapping portions 16 are fixed by the clamper 8 so as not to slip. In addition, the tension applied to the band 4 is reduced by loosening the two-layer overlapping portion 16 of the band 4 inserted in a meandering manner into the three openings 12, 13, 14 and sliding the two-layer overlapping portion 16. The band 4 can be loosened by releasing. This eliminates the troublesome work of tying the band 4 to the connecting rod 6 or loosening the band 4 by unraveling the knot 7, simplifying the tension recovery work and improving the naturally occurring band 4. Looseness can be suppressed.

  Next, an example of the operation of the sheet pressing device 3 of the agricultural and horticultural house having the above-described configuration and the procedure for stretching the band 4 will be described.

  First, the lower end side 2a shown in FIGS. 1 and 2 of the sheet 2 (see FIG. 7) retained by the skeleton 1 is placed on the outer surface (the right surface in FIG. 2) of the back wall 20b of the first member 20 in the holder 17. Then, the outer surface of the upward curved concave portion 20d is covered, and subsequently, the upward curved concave portion 20d is inserted from the opening 20a. Next, after rising along the inner surface (left surface in FIG. 2) of the back wall 20b and inserting into the downward curved concave portion 20c, and after being led out from the opening portion 20a, the wave crest of the second member 21 is flat. The first member formed by fitting the portion 21a into the downward curved concave portion 20c of the first member 20 and fitting the flat trough portion 21b of the wave of the second member 21 into the upward curved concave portion 20d of the first member 20. With the interior of the second member 21 to 20, the lower end side 2 a of the sheet 2 is sandwiched by the inner surface of the upward curved concave portion 20 d and the flat valley portion 21 b of the wave, and the inner surface of the downward curved concave portion 20 c and the wave While being pinched by the flat peak portion 21a, the lower end side 2a of the seat 2 is firmly held by the holder 17 while being pressed against the inner surface of the back wall 20b by the ridge line 21c.

  On the other hand, as shown in FIG. 2, the rear and diagonally upward locking step portions 22 c projecting from the pair of left and right leg portions 22 b of the fixing member 22 in the buckle 19 are first members 20 in the holder 17. Engaging the downward curved concave portion 20c from the lower side and holding a locking portion 22d formed by bending the lower end of each of the left and right leg portions 22b outward in the width direction and obliquely upward. The buckle 19 is easily and firmly connected to the holder 17 by engaging with the upward curved concave portion 20d of the first member 20 in FIG.

  Here, as shown in FIGS. 1 and 5, the drooping portion 4 b of the band 4 is passed through the rear side of the first horizontal bar 22 a of the fixed member 22 in the buckle 19 and the third horizontal bar 23 b of the movable member 23. It winds upward as the winding part 24 from the lower side along the rear side, and reverses upward from here to form the reversing part 25. The upper end of the upward reversing part 25 is connected to the second horizontal bar 23a of the movable member 23. The direction changer 26 is wound backward from the upper side along the front side, and the rear end of the direction changer 26 is raised along the front surface of the hanging portion 4b on the rear side of the first horizontal bar 22a, and then forward In addition, the loop portion 27 is formed by bending downward, and the front base portion of the loop portion 27 is wound forward from the lower side along the rear side of the second horizontal bar 23a to Overlapping as a laminated part 28 on the laminated part By extending the front end of 8 as a knob 28 a to the front of the buckle 19, the front base portion and the rear base portion of the loop portion 27 are interposed between the first horizontal bar 22 a and the hanging portion 4 b of the band 4. In the state, the buckle 19 is assembled to the band 4.

  In this manner, the buckle 19 is assembled to the band 4, and the loop portion 27 is pulled in the tension applying direction of the band 4 indicated by the arrow U in FIG. 5 while the buckle 19 is connected to the holder 17. The tension is applied to the band 4 by increasing the rising amount of the loop portion 27. The applied tension is applied in a backward direction by the cooperation of the second horizontal bar 23 a and the first horizontal bar 22 a of the fixed member 22 by pulling up the movable member 23 that follows the increase in the rising amount of the loop portion 27. A part of the switching part 26 and a part of the laminated part 28 that overlaps the direction changing part 26 are pinched, and an elastic contraction occurs at the time of the pinching and the facing interval w with the second horizontal bar 23a is narrowed. The winding portion 24 wound around the third horizontal bar 23b is maintained by being biased in a direction away from the second horizontal bar 23a by the elastic restoring force of the third horizontal bar 23b.

  Further, when the layered portion 28 is pulled out by pulling the knob portion 28a in the tension release direction of the band 4 indicated by the arrow P in FIG. 5, the rising amount of the loop portion 27 is reduced as shown in FIG. Since the applied tension is released and the loop portion 27 is eliminated by further pulling the knob portion 28a in the tension releasing direction, the assembly of the buckle 19 to the band 4 can be released. Applying tension and releasing tension included in recovery work are facilitated.

  As is apparent from the above description, the sheet pressing device 3 for an agricultural / horticultural house according to the present invention is required for the conventional sheet pressing device because the band 4 is connected to the holder 17 via the buckle 19. Parts such as the connecting rod 6 made of metal shafts and pipes and a number of anchors 5 supporting the connecting rod 6 (see FIGS. 7 and 8) are no longer required, reducing the number of parts and simplifying the structure. Can be achieved.

  Further, the tension application and tension release included in the tension recovery operation of the band 4 can be easily performed by pulling the band 4 assembled to the buckle 19 in the tension applying direction or pulling in the tension releasing direction. The troublesome work of tying the band 4 included in the tension recovery work of the conventional sheet pressing device shown in Fig. 5 to the connecting rod 6 or loosening the band 4 by releasing the knot 7 becomes unnecessary, and the tension recovery work. Can be facilitated, and spontaneous loosening of the band 4 can also be suppressed.
