[0009] Hereinafter, embodiments of the present invention will be described based on the drawings of the protective cover 1. Figure 1 is a perspective view showing the protective cover 1 according to the present invention. Figure 2 is an unfolded view showing the sheet 10 of the protective cover 1 according to the present invention. Figure 3 is a reference diagram showing an enlarged view of the folded portion 14. Figure 4 is a longitudinal cross-sectional view of the lower part of the protective cover 1 according to the present invention. Figure 5 is a longitudinal cross-sectional view of the lower part of the protective cover 1 showing a modified example of the protective cover 1.

[0010] As shown in Figure 1, the protective cover 1 is a resin cover made of PP or PE with a thickness of 0.5 mm to 1.0 mm, having a cylindrical main body 2 and an installation fixing part 3 provided on the lower side of the main body 2, to cover and protect the seedlings.

[0011] In this embodiment, the main body 2 is rectangular and has a height of 150 cm. The mounting and fixing part 3 is a sheet-like member whose upper end is connected to a predetermined distance (e.g., 5 cm) upward from the lower end 2a of each side of the main body 2, and which extends further outward than the predetermined distance. In this application, connection refers to the state in which the upper end of the mounting and fixing part 3 is held by the side of the main body 2 at a predetermined distance from the lower end of the main body 2. At the outer end of the mounting and fixing part 3, a ground contact piece 3a is provided via a bent portion 14, which will be described later, to contact the ground when the lower end 2a of the main body 2 is grounded. The ground contact piece 3a is provided with a hole 4 for fixing through a fastener such as a peg. In this embodiment, the mounting and fixing part 3 has a dimension of 14 cm outward from the main body 2 (of which the ground contact piece 3a is 5 cm).

[0012] In this embodiment, the protective cover 1 is assembled by folding a single resin sheet 10 as shown in Figure 2. The sheet 10 consists of a main sheet portion 11 that is folded to form the main body portion 2, and a fixing sheet portion 13 that extends from the lower end 2a of the main sheet portion 11 and has a curtain-like installation fixing portion 3. Multiple folding portions 14, 14... are provided, which are the positions where the sheet 10 is folded.

[0013] The main sheet portion 11 is provided with three vertical folding sections 14 so that it can be folded into a rectangular tube shape, and locking sections 21 and receiving sections 22 are provided at both the left and right ends to maintain the rectangular tube shape when assembled. The main sheet portion 11 is also provided with a pull-out hole 23 at the bottom through which the installation fixing section 3 is inserted. The receiving section 22 is provided with an insertion hole 22a through which the locking sections 21 on the opposite side are inserted between it and the main sheet portion 11, and a notch 22b is provided between it and the main sheet portion 11 at the upper and / or lower end so that it interlocks with the receiving section 22 on the opposite side to secure it.

[0014] The fixing sheet section 13 is provided with an installation fixing section 3 that is divided into four sections in a curtain-like shape by notches, and a folded-over section 3b between the installation fixing section 3 and the main sheet section 11. The dimensions and shape of the fixing sheet section 13 are determined so that the installation fixing section 3 can be inserted into the pull-out hole 23 when folded, and a folded-over section 14 is provided.

[0015] As shown in Figure 3, the folding section 14 is provided in a straight line with alternating fold lines 14a (perforations) to facilitate folding of the sheet 10 and oval-shaped cutout sections 14b. In this application, an oval shape refers to a shape formed by closing both ends of two parallel lines with an arc. The cutout section 14b is an oval shape extending in the linear direction (hereinafter referred to as the vertical direction) of the folding section 14, and the curvature of the arc is set to 1 / r when r is the left-right width of the cutout section 14b. The vertical length A of the cutout section 14b is sized to be less than or equal to the vertical length B of the fold lines 14a between the cutout sections 14b.

[0016] The following describes the process of folding and assembling the sheet 10 and the usage of the assembled protective cover 1. First, as shown in FIG. 4, the folded-back portion 3b is folded upward from the lower end 2a of the main body sheet portion 11 in the direction inside the main body portion 2, and each installation fixing portion 3 is inserted into the corresponding draw-out hole 23 and drawn out in the direction outside the main body portion 2. Next, the main body sheet portion 11 is folded along the bending portion 14 so as to form a square tube shape. Then, the locking portion 21 is inserted into the insertion hole 22a, and the cutouts 22b of the locked portions 22 at both the left and right ends are engaged with each other for locking. In this way, the sheet 10 is assembled as the protective cover 1.

[0017] Subsequently, the lower end 2a of the main body portion 2 of the assembled protective cover 1 is grounded so as to surround the seedlings. Then, in a state where the lower end 2a of the main body portion 2 is grounded, the installation fixing portion 3 drawn out from the draw-out hole 23 to the outside is extended to the ground, and the grounding piece 3a is fixed to the ground by passing a fixing tool such as a peg through the hole portion 4, so that the main body portion 2 can stand on its own. At this time, the installation fixing portion 3 is fixed to the ground with an angle θ so as to be separated from the main body portion 2, and the angle θ is appropriately changed according to the inclination of the ground where the protective cover 1 is installed.

[0018] According to the above-described protective cover 1, the installation fixing portion 3 is provided at a position separated from the lower end 2a of the main body portion 2 by a predetermined distance. Therefore, tension can be applied around the main body portion 2 for fixing, increasing the stability, and the protective cover 1 can be installed according to various inclinations.

[0019] Note that the protective cover according to the present invention is not limited to the aspects of the above-described embodiment, and not only the overall configuration of the protective cover but also the configuration of the installation fixing portion and the like can be appropriately changed as needed.

[0020] For example, in this embodiment, the main body portion 2 is in a square tube shape, but it may be in another shape such as a triangular tube shape, a pentagonal tube shape, or a cylindrical shape. At this time, the number of the installation fixing portions 3 can be appropriately determined regardless of the shape of the main body portion 2. However, for stability, three or more installation fixing portions 3 are provided so that the main body portion 2 is fixed by the installation fixing portions 3 from at least three directions. Furthermore, the dimensions and shape of the main body 2 and the mounting and fixing part 3 may be changed as appropriate, provided that their function as protective cover 1 is not impaired. Furthermore, to raise the main body 2 to match the slope or other surface on which the protective cover 1 is installed, an additional component may be attached to the lower end 2a of the main body 2. In this case, it is sufficient that the additional component that raises the main body 2 is in contact with the ground instead of the lower end 2a. Furthermore, fasteners or hooks may be provided to prevent the mounting and fixing part 3 from moving inward towards the main body part 2. Furthermore, although the dimensions and shapes of the four mounting and fixing parts 3 and the grounding pieces 3a are the same in the drawings of this embodiment, they may also be configured to have different dimensions and shapes to suit the slope. Furthermore, in this embodiment, the folded portion 3b is folded inside the main body portion 2, but as shown in Figure 5, the folded portion 3b may also be folded outside the main body portion 2, and the main body sheet portion 11 may be made into a rectangular tube shape, after which the installation fixing portion 3 may be bent downwards. Furthermore, in this embodiment, the cut-out portion 14b is an oval shape with arcs at its upper and lower ends, but it may also be an ellipse shape, or its upper and lower ends may not be arcs, but rather straight lines, wavy lines, polygons, etc. Furthermore, in this embodiment, the protective cover 1 is formed by folding and assembling the sheet 10, but other configurations are also possible, such as attaching the mounting and fixing part 3 to a rectangular plastic column from the outside. Furthermore, although the mounting and fixing part 3 is a sheet-like material in this embodiment, its shape and other characteristics may be changed as appropriate, as long as it can secure the main body part 2. For example, a string-like mounting and fixing part 3 is conceivable. [Explanation of Symbols]
