When the presser plate a was curved downward in a convex manner as described above, the following problems occurred. That is, first, since the edge side portion k of the presser plate a is raised from the sheet-like material h as shown in FIGS. 17(A) and 17(B), the sheet-like material is The holding of the object h became unstable, and the intended purpose of strongly and stably holding the sheet-like object h against the ground d could not be achieved. Second, when the edge portion k was raised from the sheet-like material h, there was a risk of tripping on the raised edge m. Thirdly, when the presser plate a is curved downward in a convex manner, dirt accumulates in the recess n on its upper surface and in the gap p between the raised edge part k and the sheet-like material h. There was a problem with grass growing easily.

The specific structure of the presser pin member 7 is such that the upper ends of the two left and right pin bodies 10, 10, each having a sharp lower end 8, are inserted into the insertion holes 9, 9 and pushed into the ground 3, so that the upper ends thereof are horizontal. They are connected by the connecting piece 11 having a linear shape.

In this embodiment, the left and right pin bodies 10, 10 are connected by the connecting piece 11 so as to open slightly outward, and both the pin bodies 10, 10 are elastically narrowed inward. It has been made possible. Further, the pin bodies 10, 10 can be smoothly inserted into the insertion holes 9, 9, and the presser plate 6 is guided by the pin bodies 10, 10 and slides in the length direction (vertical direction). As shown in FIG. 3, the holding plate 6 can assume the highest position in contact with the connecting piece 11. Here, "the holding plate 6 is in contact with the connecting piece 11" refers to a state in which the holding plate 6 is in contact with the entire connecting piece 11 or at least both side portions 14, 14.

The relationship between the presser pin member 7 having such a configuration and the shapes of the insertion holes 9 will be explained as follows. That is, in the overlapping state A, as shown in FIG. 6(A), both the pin bodies 10, 10 are elastically narrowed inward, and the insertion shaft portions of the pin bodies 10, 10 are It exists in the outer hole portions 15, 15 (FIG. 8) of the insertion holes 9, 9 having an elliptical shape, and the insertion shaft portion is elastically pressed against the outer edges (FIG. 6(A)). is in a state of When the distance between the two pin bodies 10, 10 is narrowed in this state, the insertion shafts of the two pin bodies 10, 10 are inserted into the inner hole portions 18, 18 (FIG. 8) of the insertion holes 9, 9. can be in a state where it exists.

In addition, the overlapping state B (see FIG. 6(A)) in which the presser pin member 7 is mounted in the vertical direction with the connecting piece 11 located at the upper end and the presser plate 6 is mounted so as to overlap the presser pin member 7 As shown in FIG. 8, on the lower surface side 5 of the presser plate 6, from the left and right insertion holes 9, 9 to the lower side of the presser plate 6 (the lower side as seen in the overlap state B). ), and the two pin bodies 10, 10 are connected to the outer edge (in this embodiment, one of the linear front and rear edges 6a, 6a) 12a of the presser plate 6. The two lower surface receiving grooves 13, 13 are provided.

The lower surface accommodating grooves 13, 13 are formed by the first and second groove-forming protrusions 16, which are protruded from the lower surface side 5 of the presser plate substrate 15 constituting the presser plate 6 so as to be left and right opposite to each other. It is formed between 16. As shown in FIG. 9, on the upper surface side 17 of the presser plate 6, from the left and right insertion holes 9, 9 to the upper side of the presser plate 6 (the upper side as seen in the overlapping state B). It extends toward the outer edge (in this embodiment, the other of the linear front and rear edges 6a, 6a) 12b of the presser plate 6, and accommodates the two pin bodies 10, 10. Two upper surface receiving grooves 19, 19 are provided. The upper surface accommodation groove 19 recesses the presser plate substrate 15 from the upper surface side 17 toward the lower surface side 5 and extends from the insertion hole 9 to the outer edge 12b of the presser plate 6 (the front and rear sides). The lower protrusion 20 is formed to reach the other edge 6a, 6a). In this embodiment, the upper surface receiving groove 19 is provided with a groove depth that does not allow the pin body 10 to protrude toward the upper surface side 17.

Further, on the upper surface side 17, there is a connecting groove 27 capable of accommodating the connecting piece 11 with a groove depth that prevents the connecting piece 11 from protruding onto the upper surface side 17. The connecting protrusion 21 is formed on the lower surface side 5 of the connecting protrusion 21 . As described above, the connecting protruding portion 21 connects the proximal end portion 22a of the base end portion 22 of the left and right lower protruding portions 20, 20 on the center side of the presser plate 6, and the proximal end portion 22a on the center side of the presser plate 6. The H-shaped reinforcing protrusion portion 25 is configured by being integrally connected to the base end portion 23 of the first groove-forming protrusion piece 16a located at. In this embodiment, the lower protrusions 20, 20 and the connecting protrusions 21, which constitute the H-shaped reinforcing protrusions 25, are formed at the same time as the upper surface accommodation groove 19 and the connecting groove 27 are formed. Ru.

The H-shaped reinforcing protrusions 25 are arranged in parallel on the left and right sides of the lower surface side 5 of the presser plate 6 when the presser plate 6 is viewed in the overlapping state B (FIG. 6(A)). The two vertical protrusions 29, 29 (FIGS. 2 and 8) that reinforce the presser plate 6 and the longitudinal center portions of the two vertical protrusions 29, 29 are integrally connected to each other. It consists of one of the connecting protrusions 21.

Then, with the two pin bodies 10, 10 accommodated in the upper surface accommodation groove 19 and the lower surface accommodation groove 13, the presser plate 6 is mounted so as to overlap the presser pin member 7. The pressing plate 6 can assume the overlapping state B (FIG. 6), and can rotate from the overlapping state B to the open state A (FIGS. 3 and 7). The presser plate 6 may overlap the presser pin member 7 at any position viewed in the longitudinal direction.

Particularly in this embodiment, as shown in FIGS. 2 and 8, the front portions 30, 30 of the first and second groove-forming protrusions 16, 16 near the outer edge 12 are directed toward the outer edge 12. They are formed as inclined surfaces 30a, 30a that are inclined toward the upper surface side 17, and the front portions 31, 31 of the lower protruding portion 20 near the outer edge 12 are formed as inclined surfaces 30a, 30a that are inclined toward the upper surface side 17. They are formed as inclined surfaces 31a, 31a that are inclined toward the side 17. The angle of inclination of the inclined surfaces 30a, 31a with respect to the presser plate substrate 15 is set to about 30 degrees.

Next, one aspect of packaging the sheet-like object presser 1 having such a configuration will be described. By accommodating the two pin bodies 10, 10 inserted into the two left and right insertion holes 9, 9 in the upper surface accommodating grooves 19, 19 and the lower surface accommodating grooves 13, 13, The overlapping state B shown in FIG. 6 is obtained. The state shown by the solid line in FIG. 6 shows the case where the presser plate 6 is placed in the overlapping state B on the upper portion 3 of the left and right pin bodies 10, 10. This is referred to as the first sheet-like object presser 1a. The state shown by the dashed line in FIG. 6 shows the case where the presser plate 6 is overlapped with the intermediate portion of the left and right pin bodies 10, 10. This is referred to as the second sheet-like object presser 1b. The first and second sheet-like object pressers 1a and 1b have a state in which the length direction of the pin bodies 10 and 10 are along the surface direction of the presser plate 6, and have a flat shape as a whole. It is showing.

The first sheet-like object presser 1a and the second sheet-like object presser 1b having such flat shapes are stacked with their orientations as seen in the vertical direction of the presser pin member 7 aligned. By the way, since the upper surface side 17 and the lower surface side 5 of the presser plate 6 are provided with the first and second groove forming protrusions 16, 16 and the lower protruding strip part 20 as described above, 1. The holding plate 6 is thicker than the holding plate substrate 15 due to the second groove-forming protrusions 16a, 16b and the lower protruding portion 20.

As described above, since the presser plates 6 have a large overall thickness, if all the presser plates 6 of the stacked sheet-like object pressers 1 were stacked one after another, the stacked state would be extremely bulky. It gets tense. However, in the present invention, as described above, the presser plate 6 can be placed at any position viewed in the length direction of the presser pin member 7. By shifting the mounting position of the holding plates 6 and reducing the number of stacked holding plates 6 at one location, the packaging form in the bulk direction can be made compact.

In the present invention, only the first sheet-like object presser 1a may be aligned in the same direction and stacked, or only the second sheet-like object presser 1b may be aligned in the stacked state, and the desired It is also possible to adopt a packaging form in which sets of, for example, five pieces are stacked one after another with the presser pin members 7 facing in opposite directions when viewed in the vertical direction.

Next, the state of use of the sheet-like object presser 1 after unpacking will be explained. In order to press and fix the sheet-like object 2 to the ground 5 using the sheet-like object presser 1 that has been taken out, the sheet-like object 2 can be pressed against the ground 3 by the lower surface side 5 of the presser plate 6. The opening state A (FIG. 7) is set as shown in FIG. Thereafter, the presser plate 6 opened in this way is supported from below with the upper part of one hand that is gripping both the pin bodies 10, 10, and the connecting piece 11 is pressed with a hammer using the other hand. Due to the striking force, the lower ends 8, 8 of the pin bodies 10, 10 break through the sheet-like material 2, and the presser pin member 7 is pushed into the ground 3. In order to firmly press the sheet-like material 2 against the ground 5, the connecting piece 11 is pressed with a hammer until the pressing plate 6 sinks into the ground 5.

3 to 5 show a state in which the pressing plate 6 is sunk into the ground 3 and the sheet-like material 2 is strongly pressed against the ground 3. In this way, even if the connecting piece 11 is strongly hit with a hammer until the holding plate 6 sinks into the ground 3, the holding plate 6 will be deformed by the reinforcing action of the H-shaped reinforcing ridges 25. It's hard to let it happen.

To explain this reinforcing effect, even if the presser plate 6 sinks into the ground 3, the two vertical protrusions arranged in parallel on the left and right sides of the lower surface side 5 of the presser plate 6 The strips 29, 29 (configured by the lower protrusion 20 and the groove forming protrusion 16 being integrally connected via the connecting protrusion 21) hold the presser plate 6 on its lower surface. By reinforcing the side 5, the parts 35, 35 (FIG. 3) on both sides of the connecting piece 11 of the presser plate 6 are bent downwardly to convexly (as indicated by the arrow F1 in FIGS. 3 and 5). (curved deformation shown in ). Furthermore, the connecting protrusion 21 prevents the portion 36 of the holding plate 6 between the insertion holes 9 and 9 from deforming in a downwardly convex manner (curving deformation indicated by arrow F2 in FIG. 3). do. Such a reinforcing effect can be reliably obtained because the H-shaped reinforcing protrusion 25 (FIG. 8) is integrated as a whole.

Therefore, the sheet-like material 2 can be strongly and stably pressed against the ground 5 by the flat-shaped presser plate 6. Furthermore, unlike in the conventional case, the edge portion 37 of the presser plate 6 is unlikely to be lifted off the sheet-like object 2, so there is no risk of tripping on the raised edge, unlike in the conventional case. Furthermore, since the edge portion 37 is unlikely to be lifted up from the sheet-like object 2, the presser plate 6 formed by the gap between the lifted edge-side portion 37 and the sheet-like object 2 or by curved deformation. The above-mentioned problem of the prior art, in which dirt accumulates in the recessed portion of the upper surface side 17 and grass tends to grow there, is less likely to occur.

Particularly in this embodiment, as shown in FIGS. 3 and 5, the connecting groove 27 is provided with a groove depth that prevents the connecting piece 11 from protruding toward the upper surface side 17, so that the presser plate 6 is With the sheet-like material 2 pressed against the ground 5, the upper surface side 17 can be formed flat. Therefore, dirt is less likely to accumulate on the upper surface side 17 of the presser plate 6, and grass is less likely to grow on the upper surface side.

Further, in this embodiment, as shown in FIGS. 2 and 8, the front portions of the first and second groove-forming protrusions 16, 16 near the outer edge 12 are directed toward the outer edge 12 and toward the outer edge 12. It is formed as an inclined surface 30a that is inclined toward the upper surface side 17. Therefore, when the presser plate 6 is sunk into the ground 5, the sheet-like material 2 is pressed against these inclined surfaces 30a and 31a, as shown in FIG. The sheet-like material 2 can be held down easily at the portions of the second groove-forming protrusions 16, 16 and the lower protrusions 20 near the outer edge 12, and the edge-side portion 37 of the presser plate 6 can be pressed. This can prevent the surface from rising slightly.

As shown in FIG. 10, for example, the sheet-like object presser 1 according to the present invention includes the presser plate 6 according to the embodiment described above, and the upper ends of the two pin bodies 10, 10 each having an upwardly convex arc shape. It can also be constructed using U-shaped presser pin members 7 connected by connecting pieces 11. The presser plate 6 used in this case may be provided with the connecting groove 27 shown in FIG. 2, which is not required, even if the connecting groove 27 is not provided. It may also be provided with a connecting protrusion 21 shown in FIG. 11, which is not shown in FIG.

When constructing a sheet-like object presser using the U-shaped presser pin member 7, as shown in FIG. 44, the presser plate 6 assumes its highest position when it is in contact with both end portions 45, 45 of the arc-shaped connecting piece 11. In this state, by pressing the connecting piece 11 with a hammer, the presser pin member 7 is pushed into the ground 3, and even if the presser plate 6 is sunk into the ground 5, both insertion holes of the presser plate 6 It is possible to suppress the portion between the portions 9, 9 from deforming into a downwardly convex curved state (curved deformation as shown by arrow F3 in FIG. 10). This is because the holding plate 6 is reinforced by the H-shaped reinforcing ridges 25, and in particular, the connecting ridges whose both ends are integrally connected to the vertical ridges 29, 29. 21 (FIG. 8).

12 to 15 show other embodiments of the sheet-like object presser 1 according to the present invention, which is a sheet-like object presser that presses and fixes the sheet-like object 2 to the ground 5. The holding plate 6 having the same structure as in No. 1 is used upside down.

That is, the sheet-like object presser 1 is in the open state A (FIGS. 14(C), 15) in which it is opened so that the sheet-like object 2 can be pressed against the ground 3 on the lower surface side 5 (FIG. 13). ) and a presser pin member 7 for pressing the presser plate 6 against the ground 3, the presser plate 6 and the presser pin member 7 are formed separately, and the presser plate 6 is 14(A) and 14(B), it is configured so that it can be attached to the presser pin member 7 in an overlapping state B in which it overlaps the presser pin member 7.

As shown in FIGS. 12 and 13, the presser plate 6 is provided with two left and right insertion holes 9, 9 at a required interval, and the presser pin member 7 is provided with two insertion holes 9, 9 at a required interval.

The presser pin member 7 may have the above-mentioned U-shape or may have the above-mentioned U-shape.

The presser plate 6 can be guided by the pin bodies 10, 10 and slid with the pin bodies 10, 10 inserted into the insertion holes 9, 9. When the presser pin member 7 has a U-shape, for example, the presser plate 6 is in contact with the connecting piece 11 (abutting the entire connecting piece 11 or at least both side portions 14, 14) at the highest point. (Figure 15). Further, as shown in FIG. 14, the presser plate 6 is attached such that the presser pin member 7 is oriented vertically with the connecting piece 11 located at the upper end, and the presser plate 6 overlaps the presser pin member 7. As shown in FIG. 14(A) in the overlapping state B, there are holes in the upper surface side 17 of the presser plate 6 extending from the left and right insertion holes 9, 9 toward the upper side of the presser plate 6. It has two upper surface receiving grooves 19, 19 which extend from the outer edge 12 of the presser plate 6 and accommodate the two pin bodies 10, 10 therein. Each of the upper surface accommodation grooves 19, 19 is formed between first and second groove-forming protrusions 16, 16 that are protruded from the upper surface side of the presser plate substrate 15 constituting the presser plate 6, facing each other from left to right. has been done.

On the lower surface side 5, as shown in FIG. 14(B), there are holes extending from the left and right insertion holes 9, 9 toward the lower side of the presser plate 6 and connected to the outer edge 12 of the presser plate 6. Two lower surface receiving grooves 13, 13 are provided in which the two pin bodies 10, 10 are accommodated. The lower surface accommodation grooves 13, 13 are configured to recess the presser plate substrate 15 from the lower surface side 5 toward the upper surface side 17, and to extend the outer edge of the presser plate 6 from the insertion holes 9, 9 to the upper surface side 17. Upper protrusions 47, 47 extending up to 12 are formed.

Further, a connecting protrusion 49 (FIG. 14(A)) is provided on the upper surface side 17 to connect the insertion holes 9, 9, and the connecting protrusion 49 is as shown in FIG. Base end portions 51, 51 of the base end portions 50, 50 of the left and right upper protruding stripes 47, 47 on the center side of the presser plate 6, and the first groove forming protrusion located on the center side. By being integrally connected to the proximal end portions 52, 52 of the pieces 16a, 16a, an H-shaped reinforcing ridge portion 25 having a series of H-shaped outer shapes is formed.

In the presser pin member 7, when the two pin bodies 10, 10 are inserted into the insertion holes 9, 9, the connecting piece 11 is attached to the upper part of the connecting protrusion 49, as shown in FIG. 53 (this is the case where the presser pin member has a U-shape and abuts the entire connecting piece 11 or at least both side portions 14, 14) or apart (as shown by the dashed dotted line in FIG. 15). When the presser pin member 7 has a U-shape, as shown in FIG.

Then, as shown in FIG. 14, in a state where the two pin bodies 10, 10 are accommodated in the upper surface accommodating grooves 19, 19 and the lower surface accommodating grooves 13, 13, the presser plate 6 The presser plate 6 can exhibit the overlapping state B (FIGS. 14(A) and 14(B)) in which it is attached so as to overlap the member 7, and the presser plate 6 can exhibit the overlapping state B as shown in FIG. 14(C). It can be rotated from the state to the open state A.

In this embodiment as well, the sheet-like object presser 1 having such a configuration has the presser plate 6 overlapped with the upper part and the lower part of the left and right pin bodies 10, 10, as in the first embodiment. With the length direction of the pin bodies 10, 10 extending along the surface direction of the presser plate 6, the pin bodies 10, 10 can be installed in a flat shape as a whole, and the packaging form in the bulk direction can be made compact.

The usage condition of the sheet-like object presser 1 after unpacking is the same as in Example 1, and the sheet-like object 2 is pressed and fixed on the ground 3 using the sheet-like object presser 1 taken out. supports the holding plate 6 (FIG. 14(C)) in an open state from below with the upper part of one hand that is holding both the pin bodies 10, 10, and holds the connecting piece with the other hand. Hit 11 with a hammer. Due to the striking force, the lower ends 8, 8 of the pin bodies 10, 10 break through the sheet-like material 2, and the presser pin member 7 is pushed into the ground 3. In order to firmly press the sheet-like material 2 against the ground 5, the connecting piece 11 is pressed with a hammer until the pressing plate 6 sinks into the ground 3.

Even if the presser plate 6 is sunk into the ground 3 due to the striking force, the presser plate 6 is not easily deformed due to the reinforcing action of the H-shaped reinforcing ridges 25. This is because the H-shaped reinforcing ridges 25 are formed on the upper surface side 17, and the reinforcing action of the H-shaped reinforcing ridges 25 prevents deformation of the presser plate 6.

For this reason, as in Example 1, the edge portion 37 of the presser plate 6 is unlikely to be lifted off the sheet-like object 2, and therefore the sheet-like object 2 is held on the ground by the plate-shaped presser plate 6. It can be strongly held in a stable state. In addition, since the edge portion 37 is unlikely to be lifted up from the sheet-like object 2, unlike the conventional method, the gap between the raised edge-side portion and the sheet-like object 2, or the gap formed by curved deformation. This prevents the problem that soil is likely to accumulate in the depression at the top of the holding plate 6 and grass grows easily.

The state shown by the solid line in FIG. 15 shows the state in which the sheet-like object 2 is fixed to the ground 3 using the U-shaped sheet-like object holding device 1, and the state shown by the dashed line in FIG. The state shows a state in which the sheet-like object 2 is fixed to the ground 3 using the U-shaped sheet-like object presser 1.
