  The thing of patent document 1 is proposed as an example of the sheet-like material pressing tool which presses and fixes a sheet-like material, such as an agricultural multi-sheet, on the ground. As shown in FIG. 31, one mode of the sheet-like material presser a is formed by connecting two shafts c and c that are pushed into the ground at both ends of the arcuate piece b protruding upward. An inverted U-shaped presser pin d in which the shafts c and c are opened in a U-shape and two insertion holes e and e through which the shafts c and c can be inserted in the vertical direction are provided. And a presser plate f.

  Then, when the sheet-like object presser a is used to hold the sheet-like object h laid on the ground g from above and fix it to the ground g, it is placed on the sheet-like object h as shown in FIG. After the two shafts c and c are elastically constricted in the two insertion holes e and e provided in the presser plate f, the lower end portions j and j are inserted, The shafts c and c are pierced into the sheet-like material h and pushed into the ground. As a result of this pushing, the shafts c and c expand to the left and right in the ground. Therefore, even if an attempt is made to pull out the holding pin d by grasping the arc-shaped piece b, an extremely large force is required due to the resistance of the soil. The sheet-like material h in the pressed state has an effect that it is not peeled off by the force of being blown by the wind.

  As described above, the sheet-like material presser a disclosed in Patent Document 1 is configured so that the two shafts c and c are inserted through the two insertion holes e and e provided in the presser plate f. Since the pin d is pushed downward, and thereby the both axes c and c are expanded to the left and right in the ground, the arc portion as the grip k formed on the upper side of the presser plate f is the presser. The insertion gap m of the hand formed with the plate f is reduced depending on the pressing degree of the pressing pin d. In this case, it is difficult to insert the hand into the insertion gap m, and there is a problem that it becomes impossible to grasp the grip k and pull out the presser pin.

The length L5 is set to about 17 mm, the length L6 of the upper bent piece 16 is set to about 21 mm, and the length L7 of the connecting piece 14 is set to about 80 mm.

  However, when fixing the sheet-like material 3 to the ground 2 by using the sheet-like material retainer 1 having such a configuration, first, as shown in FIGS. 6 (A) and 6 (B), both pin bodies 11, 11 is opened and the lower end portions 23 and 23 are inserted into the left and right pin insertion holes 10 and 10 of the presser plate 5. Thereafter, as shown by an arrow in FIG. 6 (B), the presser plate 5 is guided by both pin bodies 11 and 11 and slid upward, and the presser plate 5 is moved as shown in FIG. 6 (C). In this state, the highest position A is exhibited. These operations are preferably performed by holding the grip 20 with a hand 18 as shown in FIG.

  In this embodiment, in this state, the fingers (both index finger 31a and pinky finger 31b in FIG. 6) 31, 31 are in contact with the upper sides of the left and right outward bent pieces 13, 13.

  Thereafter, at the place where the sheet-like material 3 is to be fixed to the ground 2, as shown in FIG. 7A, the sheet-like material 3 is broken through the lower ends 32, 32 of the left and right pin bodies 11, 11. As shown in FIG. 7B, the presser pin member 6 is pushed into the ground 2 while holding the grip portion 20 with the hand 18. This pushing operation can be performed stably because the fingers 31 on both sides are in a state of pressing the left and right outward bent pieces 13 and 13 from above.

  FIG. 7B shows a state in which the presser plate 5 is pressed downward by the left and right outer bent pieces 13 and 13 and pressed against the upper surface 33 of the sheet-like object 3. Thereby, the sheet-like object 3 is stably fixed to the ground 2. In this embodiment, since the pressing pin member 6 includes left and right outward bent pieces 13 and 13, as shown in FIGS. 7B and 8, the left and right outward bent pieces 13 and 13 are provided. Thus, both side portions 35, 35 of the presser plate 5 can be stably pressed toward the ground 2, and the sheet-like object 3 can be more stably pressed and fixed to the ground.

  Even in a state where the sheet-like object 3 is securely pressed in this way, as shown in FIG. 8, the restricting portions 27 and 27 (outward bent piece portions) are provided between the holding plate 5 and the grip portion 20. Due to the gap holding action of the gap holding portions 27, 27 as 13, 13), the insertion gap 30 for inserting the hand tip is formed between the presser plate 5 and the grip portion 20.

  When removing the sheet-like material 3 from the ground 2, as shown in FIG. 9A, a hand is inserted into the insertion gap 30 and the grip portion 20 is gripped with a hand 18, and the left and right pin bodies 11 are removed. , 11 is pulled out from the ground.

Both pin bodies 11, 11 are pulled out while the plate 5 is in the highest position A. In other words, when the presser pin member 6 is pulled out, the presser plate 5 is lifted together with the left and right pin bodies 11 and 11. Therefore, it is possible to reduce the trouble of collecting the presser plate 5 remaining on the sheet-like material 3 after the presser pin member 6 is removed, and the work efficiency can be achieved.

  FIG. 10A shows another procedure for pressing and fixing the sheet-like material 3 to the ground 2 using the sheet-like material retainer 1. For example, in the case of work in the presence of wind, in order to prevent flapping of the sheet-like object 3, first, the pressing plate 5 is brought into contact with a required portion of the upper surface 33 of the sheet-like object 3 to maintain the corresponding contact state. In the same manner as described above, the grip portion 20 is gripped by hand. In this state, as shown in FIG. 10 (B), the left and right pin bodies 11 and 11 are opened and the lower end portions 23 and 23 of the both pin bodies 11 and 11 are opened to the two pin insertion hole portions 10 and 10. The presser pin member 6 is pushed into the ground 2 by breaking through the sheet-like material 3. Thereafter, as shown in FIG. 10C, the both pin bodies 11, 11 are pushed into the ground until the left and right outward bent pieces 13, 13 come into contact with the upper surface 25 of the presser plate 5. As a result, as shown in FIG. 10C, the sheet-like object 3 can be stably pressed and fixed to the ground 2 via the pressing plate 5.

  As described above, when the sheet-like material presser 1 is used, the gripping portion 20 can be gripped and the presser pin member 6 can be pushed into the ground 2 in a stable state, and the gripping portion can be used without using a special tool. The presser pin member 6 can be easily pulled out of the ground in a stable state by grasping 20.

  When packing and shipping the sheet-like material retainer 1 having the above-described configuration, as shown in FIG. 11, a space 34 between the left and right pin bodies 11 and 11 is effectively used to hold the retainer in the space 34. The plate 5 can be arranged and packed in a flat state as a whole. At this time, a plurality of presser pin members 6 may be stacked, or a plurality of presser plates 5 may be stacked.

The upper end portions 17 and 17 of the upper bent pieces 39 and 39 are connected to each other, for example, a connecting piece 24 having a horizontal linear shape. The connecting piece 24 has a grip portion 20 for gripping with a hand.

  Also in this case, the lower end portions 23 and 23 of both pin bodies 11 and 11 are inserted into both pin insertion holes 10 and 10 of the presser plate 5 having the same structure as described above, and the presser plate 5 is connected to both pin bodies 11 and 11. 11 and is slid upward to reach the most elevated position A. As shown in FIG. 12 (B), the inwardly bent piece portion is interposed between the presser plate 5 and the grip portion 20. An insertion gap 30 into which the hand is inserted is formed by the gap holding action of the restriction portions 27 and 27 as 36 and 36. When the presser pin member 6 is pushed into the ground 2, the inwardly bent piece portions 36, 36 hold the both side portions 35, 35 of the presser plate 5 toward the ground 2 in a stable state. Even in this embodiment, both the pin bodies 11 and 11 can elastically hold the portion 26 between the pin insertion holes of the presser plate 5 in a state where the presser plate 5 is in the most elevated position A. Has been made.

  Even when the sheet-like material presser 1 is used, it is possible to hold the grip portion 20 with a hand and push the presser pin member 6 into the ground 2 in a stable state. By this pushing, the sheet-like material 3 is pressed against the ground 2. When the presser pin member 6 is pulled out, it is possible to easily pull out the presser pin member 6 from the ground by inserting a hand into the insertion gap 30 and grasping the grip portion 20 with a hand.
