  However, the following problems have occurred with conventional sandproof sheets. That is, when the cord 92 shown in FIG. 8 deteriorates or is blown by a strong wind, when the cord 92 is loosened, a gap is easily generated between the supporting column 2 and the sandproof sheet 1 in the vicinity thereof. . In addition, since the same cord material 92 is inserted and tied to the support 2, if the cord material 92 is loosened, a relatively large gap is easily formed between the adjacent sandproof sheets, and sand scattering can be effectively prevented. There wasn't. Furthermore, when a gap is generated between the sandproof sheet 1 and the ground 94, there is also a problem that the sand flows in from the gap.

  On the other hand, when the rope 92 is firmly connected to the support column 3, there is a problem that the work of unwinding the rope when removing the sandproof sheet is troublesome. Further, if the cord 92 is damaged due to deterioration, it cannot be used again, so that an economical problem has been pointed out.

  This invention is made | formed in view of the above problems, and the subject which this invention tends to solve is making the removal operation | work of a sand-proof sheet | seat simple while preventing sand scattering effectively.

In order to solve the above-mentioned problems, the present invention takes the following means.
First, the first invention is a sandproof sheet of a size shape between the struts attached to struts installed at predetermined intervals and stretched between the struts, and the sandproof sheet is attached to the struts. A plurality of ears are formed at predetermined intervals on the edge, and the ears are wound around the support column and the ends thereof are connected to a part of the sand control sheet by a detachable means so that the sand control sheet is attached to the support column. The ear | edge part provided between adjacent sand-proof sheets attached to a support | pillar is arrange | positioned alternately by the axial direction of a support | pillar, It is characterized by the above-mentioned.

  According to the first invention, a plurality of ears are formed at predetermined intervals on the mounting edge of the sandproof sheet to the column, and the ears are wound around the column, so that a gap between the sandproof sheet and the column is less likely to occur. , Can prevent sand scattering. In addition, since the sandproof sheet is attached to the column by connecting the end of the ear part wound around the column to a part of the sandproof sheet by the detachable means, the sandproof sheet stretched as necessary is attached. It can also be removed easily. Furthermore, when the ear portions provided between adjacent sandproof sheets attached to the support columns are alternately arranged in the axial direction of the support columns, it becomes difficult to generate a gap between adjacent sandproof sheets, and effectively prevent the sand from scattering. Can do.

  Here, the ear portion formed in the present invention may be integrally formed in advance when the sandproof sheet is formed, or may be formed by separately attaching only the ear portion later. The length of the ear | edge part should just be a length of the grade in which the edge part is connected with a part of sandproof sheet, when an ear | edge part is wound around the support | pillar. Moreover, in order to make an attachment state favorable, it is preferable that the length of the axial direction of the some ear | edge part formed in an attachment edge is the same length.

  Next, according to a second aspect of the present invention, in the disaster prevention sheet according to the first aspect, the detachable means for connecting the end portion of the ear portion and a part of the sandproof sheet is the upper end of the end portion of the ear portion. Connecting the ear-side coupling member provided from the bottom to the bottom and the sand-proof sheet-side coupling member formed and arranged at the corresponding position of the sand-proof sheet where the end is positioned when the ear is wound around the support It is comprised from the connection member so that attachment or detachment is possible.

  According to 2nd invention, the operation | work which attaches a sandproof sheet to a support | pillar becomes simple by forming the ear | edge part side coupling member and the sandproof sheet side coupling member. Moreover, the operation | work which removes a sand-proof sheet from a support | pillar will become easier if the detachable connection member which connects both is used as a detachable means.

  Next, a third invention is characterized in that in the sandproof sheet according to the second invention described above, the coupling member is formed in a ladder shape.

  According to the third aspect of the invention, when the ear portion side coupling member and the sandproof sheet side coupling member are formed in a ladder shape, the attachment and detachment work of the sandproof sheet is simplified because the connecting member is easily detached. Further, the connecting member can be connected at an arbitrary position of the connecting member.

  Here, in the present invention, in order to “form in a ladder shape”, for example, as shown in FIG. 6A, a substantially semicircular shape (ladder processing) at a predetermined size interval from the upper end to the lower end of the coupling member 5. It can be formed by sewing the string-like member 51 to the connecting member 5 so that a gap 52 is formed in the connecting member 5. Also, it can be formed by sewing into a rectangular shape (N ladder processing) as shown in FIG. In addition, in order to endure the tensile strength by the coupling | bonding of the ear | edge part side coupling member and the sand-proof sheet side coupling member, it is preferable that a coupling member is formed by the ladder process shown to Fig.6 (a).

  Next, a fourth aspect of the present invention is the sandproof sheet according to any one of the first to third aspects of the invention, wherein the sandproof sheet has a size that closes the gap between the sandproof sheet and the ground installed below the sandproof sheet. A connecting member is provided on both side edges of the hanging portion from the upper end to the lower end, and the connecting member is constituted by a connecting member that connects another adjacent sandproof sheet connecting member. It is characterized by.

  According to the fourth invention, since the connecting members of the adjacent sandproof sheets are connected by the connecting member, the lower end portion of the hanging portion does not flutter due to strong wind or the like. Therefore, it is possible to prevent a gap from being generated between the sandproof sheet and the ground, and to prevent the sand from scattering.

  Next, a fifth invention is characterized in that in the sandproof sheet according to the second to fourth inventions described above, the connecting member is formed of a hook-and-loop fastener.

  According to 5th invention, since a coupling | bonding member becomes easy by using a hook-and-loop fastener as a connection member, the attachment and removal operation | work of a sand-proof sheet becomes easy. As such a thing, the surface fastener 8 shown to Fig.7 (a) is mentioned, for example. The surface fastener 8 has a loop surface 81 at its upper end and a hook surface 82 at its lower end. The loop surface 81 and the hook surface 82 are attached to a fastener base material 83, and an intermediate member 84 is disposed between the base materials. When this hook-and-loop fastener 8 is rounded, the loop surface 81 and the hook surface 82 are joined as shown in FIG. 8B, and a ring-shaped connecting member is formed as a whole. When the ear portion side coupling member and the sandproof sheet side coupling member are coupled as such a ring-shaped coupling member, the operation of attaching and removing the sandproof sheet becomes simple. In this case, if a cloth such as a strong tent material is used as the material of the intermediate member, even if it is deteriorated or dirty, it can be washed and reused as many times as there is an economic advantage. is there.

The present invention can obtain the following effects by taking the above-described means.
First, in 1st invention, while preventing scattering of sand effectively, the removal operation | work of a sandproof sheet can be simplified.
Next, according to 2nd invention, the operation | work which removes a sand-proof sheet from a support | pillar becomes simpler.
Next, according to the third aspect, the work of attaching and removing the sandproof sheet is simplified.
Next, according to 4th invention, while making it difficult to produce a clearance gap between a sand-proof sheet and the ground, scattering of sand can be prevented.
Next, according to the fifth aspect, the work for attaching and removing the sandproof sheet is simplified.

  The sandproof sheet according to the present invention is a sandproof sheet that is stretched adjacent to the sand and effectively prevents scattering of sand. Therefore, it is preferable to stretch along a sandy sandy beach or near a residence near a dune. If a sandproof sheet is stretched adjacent to such a place with a lot of sand, scattering of sand can be effectively prevented.

  It is preferable that the sand-proof sheet is a rectangular mesh having a size that prevents passage of sand grains on sandy beaches and dunes. This is because if the size is too small, the windproof sheet is subjected to a large wind pressure, and the stretched state of the sandproof sheet becomes unstable. Specifically, the size is preferably about 3.0 × 1.2 to 1.4 mm. In addition, when a sandproof sheet is stretched in the vicinity of the sandy beach, a picture of whales or fish can be drawn on the sandproof sheet without damaging the landscape.

Embodiments of the present invention will be described with reference to FIGS.
FIG. 1 is a front view showing a sandproof sheet according to the present embodiment. 2 and 3 are perspective views showing a state in which the sandproof sheet 1 according to the present embodiment is attached to the support column 2 adjacently. In addition, FIG. 3 is the perspective view which looked at the support | pillar 1 in FIG. 2 from the opposite position as symmetry.

  As shown in FIG. 1, the sandproof sheet 1 according to the present embodiment includes a plurality of ears 3 formed at predetermined intervals on a mounting edge 31 to a support column 2 (see FIGS. 2 and 3), and a ground 94 (FIG. 2, and a bag-shaped tube portion 4 through which a beam spanning the support column 2 is inserted. When the plurality of ear portions 3 are configured and stretched, the stretched state of the sandproof sheet 1 is stabilized. As shown in FIGS. 2 and 3, the sandproof sheet 1 is coupled to the sandproof sheet 1 disposed at the corresponding position of the sandproof sheet 1 where the end portion is positioned when the ear 3 is wound around the support 2. A member 6 is formed.

  The ear part 3 is provided with an ear part side coupling member 5 from the upper end to the lower end of the end part. This ear | edge part side connection member 5 is sewn by the ladder process of the string-shaped member 51, and is formed in the shape of a ladder. Moreover, as shown in FIG. 2 and FIG. 3, the ear portions 3 are alternately arranged in the axial direction of the struts 2 between adjacent sandproof sheets attached to the struts 2. Thereby, when the sandproof sheet 1 is stretched, the stretched state becomes strong, so that a gap is not easily generated between adjacent sandproof sheets, and sand scattering can be effectively prevented.

  The hanging portion 12 is provided with a hanging portion side coupling member 13 from the upper end to the lower end of both end edges. The hanging portion side coupling member 13 is sewn by ladder processing of the string-like member 51 and is formed in a ladder shape. Thereby, it becomes the structure that the perpendicular | vertical-part side coupling member of the other adjacent sandproof sheet can be connected by a connection member. Further, below the hanging portion 12, the hanging portion lower grounding member 14 is sewn by daring the string-like member 51 to form a ladder shape. Thereby, when the hanging part 12 contacts the ground, the pain to the hanging part 12 can be prevented.

Next, based on FIG. 2 and FIG. 3, the attachment method to the support | pillar 2 of the sandproof sheet 1 which concerns on a present Example is demonstrated.
The ear | edge part 3 of the adjacent sand-proof sheet 1 is wound around the support | pillar 2, and the sand-proof sheet 1 is attached to the support | pillar 2 when the ear | edge part side coupling member 5 and the sand-proof sheet side coupling member 6 connect. The ear side coupling member 5 and the sandproof sheet side coupling member 6 are connected by a hook-and-loop fastener 8 that is a coupling member. Thereby, since connection of each coupling member becomes easy, the attachment work of the sandproof sheet 1 becomes simple. In the present embodiment, the two hook-and-loop fasteners 8 are connected to each other. However, when the number of hook-and-loop fasteners 8 to be connected is increased, the stretched state of the sandproof sheet 1 becomes more stable.

  FIG. 4 is a front view showing a stretched state of the sandproof sheet 1 attached to the column 2 as described above. In the sandproof sheet 1 according to the present embodiment, the ear portions 3 provided between the adjacent sandproof sheets are alternately arranged in the axial direction of the pillars at equal intervals and attached to the pillars 2. If it does so, like the conventional sandproof sheet 1 shown in FIG.8 (b), a clearance gap hardly arises between the sandproof sheets to connect. Further, since the alternately arranged ear portions 3 are wound around the same column 2, there is almost no gap between the column 2 and the sandproof sheet 1. Thereby, scattering of sand can be prevented effectively.

  Moreover, the vertical part side coupling member 13 of adjacent sandproof sheets is connected by a hook-and-loop fastener 8 that is a connecting member. Thereby, the lower end portion of the hanging portion 12 is less likely to wrinkle due to strong winds and the like, and a gap is hardly generated between the sandproof sheet and the ground, so that scattering of sand can be prevented.

  In order to remove the sandproof sheet 1 from the support column 2, the end of the ear part 3 wound around the support column 2 may be detached by removing the hook-and-loop fastener 8. That is, unlike the conventional sandproof sheet 1 shown in FIG. 8, there is no troublesome work of unwinding the cords 92 that are tightly tied together, and therefore, the work of removing the stretched sandproof sheet 1 becomes simple.

FIG. 5 is an explanatory diagram illustrating an example in which the sandproof sheet 1 according to the present embodiment is applied near a residential area along the sandy beach. In FIG. 5, the upper left direction is the sea side, and the lower right direction is the residential area side.
As shown in FIG. 5, when a large number of sandproof sheets 1 according to the present embodiment are stretched side by side on columns that are installed at equal intervals, sand scattering from the sea side to the residential area side can be prevented. Further, in the area where the sandproof sheet 1 is temporarily removed, it is preferable because the work becomes simple even when a neighboring resident removes the sandproof sheet 1. Furthermore, when the hook-and-loop fastener 8 shown in FIG. 7 (a) is used as a connecting member, it can be washed and reused even when it becomes dirty, and there are economical advantages when many sandproof sheets are stretched. is there. In addition, when the columns are added at the same interval, the extension work can be simplified if the sandproof sheets having the size of the column interval are stretched in the same manner.

The present invention is not limited to the configuration of the above embodiment, and can be implemented in various other forms.
For example, in the above-described embodiment, an example in which the ear part side coupling member 5 and the sandproof sheet side coupling member 6 are connected by the hook-and-loop fastener 8 as the detachable means is shown. It may be configured to be tightened and coupled with nuts and the like.
Moreover, although the example in which the hook_and_loop | surface fastener 8 is used as a connection member was shown, when using the lock clip 80 shown in FIG.7 (c), the sandproof sheet side coupling member 5 and the ear | edge part side coupling member 6 are hooked and connected. It may be.
Moreover, although the example which the support | pillar 2 was installed at equal intervals was shown, when the support | pillar is not installed at equal intervals, this invention can be applied according to the magnitude | size shape between each support | pillar.
