Description

  The present invention relates to a fruit sunshade for preventing sunburn of fruits such as melons and squash.

  Fruits such as melon, saiban, nanban, and winter cocoon are reduced in commercial value upon shipping if sunburn (discoloration of the surface color, uneven color) occurs during the cultivation. For this reason, the sunshade for preventing the sunburn of a fruit conventionally is proposed (for example, refer patent document 1).

This is because the sun protection body is formed from a non-woven fabric, and at least one incision is formed from the end to the approximate center, and the left and right body parts of the incision are drawn to form a substantially umbrella shape. The part is fixed and attached to the fruit.
No. 8-3260

  However, since the sunshade body is made of non-woven fabric, its own rigidity is low, and its water absorption is high, so it is difficult to maintain the umbrella shape during fruit cultivation. In addition, since the rigidity is low, after polymerization is performed so that the left and right main body parts of the incision are drawn to form a substantially umbrella shape, the polymerized part must be fastened with a stepper or the like in order to maintain the polymerization state. There was annoying work that had to be done.

  Then, this invention makes it a subject to provide the sunshade for fruits which can hold | maintain the sunshade shape with respect to a fruit, without using a fastening means specially in view of the said conventional problem.

  The sunscreen for fruits of the present invention is formed from a single sheet of synthetic resin, and resists the elasticity of the synthetic resin so that it protrudes sideways from both sides in the width direction of the bottom and the bottom of the fruit. The cover is integrally provided with a cover that is bent and covers the fruit on its side and above, and holds the curved state by being locked by the elastic restoring force of the cover while the ends of the cover are overlapped. The latching means to be made is provided in the edge part of the said cover part, It is characterized by the above-mentioned.

  The fruit sun cover having the above-described structure is formed from a synthetic resin sheet, and is provided with locking means for holding the state of covering the fruit by the elastic restoring force of the synthetic resin. The shape of the sunshade is kept without using any special fastening means, and since it is made of synthetic resin, it is less likely to deteriorate even when exposed to wind and rain, and protects the fruit over the long term. Low and avoids the condition where the fruit is exposed to unwanted moisture.

  In the fruit sunscreen of the present invention, the locking means includes a notch formed at the end of one cover and a cover formed between the notches formed at the end of the other cover and inserted into the notch. It is characterized by comprising an insertion piece that is locked by an elastic restoring force.

  If the insertion piece formed in the other cover part is inserted into the notch formed in one cover part, the cover part tends to expand due to the elastic restoring force of the synthetic resin. The insertion piece is locked by the spreading force and the state of covering the fruit is maintained.

  In the fruit sunscreen of the present invention, as a locking means, in the longitudinal direction perpendicular to the width direction from the one notch in a state where one notch formed in one covering part and the covering parts are overlapped vertically. The other incision formed in the other cover portion at an interval, the one insertion piece formed in the other cover portion and inserted into the one incision, and the other incision formed in the one cover portion The other insertion piece inserted in is provided.

  By providing a plurality of pairs of cuts and insertion pieces as in the above-described configuration, the sun covering state of the fruit is maintained with the locking force increased accordingly.

  The fruit sunscreen of the present invention is characterized in that one insertion piece is inserted into one cut from above and the other insertion piece is inserted into the other cut from below.

  As in the above configuration, a plurality of pairs of notches and insert pieces are provided, and the insert pieces are inserted into the notches from different directions, whereby the direction of the vector of the locking force is different.

The fruit sunscreen of the present invention is characterized in that a linear thin-walled portion parallel to the longitudinal direction perpendicular to the width direction is formed in the middle of the covering portion.
According to this configuration, since the thin portion is a fragile portion, if the cover portion is bent with the thin portion as a guide, the cover portion can be extremely easily bent.

  The fruit sunscreen of the present invention is configured such that an insertion hole for inserting a fruit vine is formed in the overlapped end portion in a state where the end portions of the respective cover portions are overlapped with each other. It is characterized by that.

According to this configuration, if the vine is led out from the insertion hole corresponding to the kind of the fruit, the fruit and the sun covering are integrated, and the fruit is stabilized in the sun covering.

The fruit sunscreen according to the present invention is characterized in that the longitudinal direction of the bottom is set smaller than the longitudinal direction of the covering.
Since the area of the bottom portion is reduced as in the above configuration, the area receiving the wind is reduced by that amount, and the sun covering becomes difficult to move, so that the fruit is easily stabilized in the sun covering.

The sunscreen for fruits of the present invention is characterized in that the sheet is formed of a foamable synthetic resin.
According to the said structure, a sheet | seat can be manufactured cheaply, and also it becomes possible to give predetermined | prescribed elasticity, and the sunshade shape of a fruit is hold | maintained by a latching means.

  The fruit sunscreen of the present invention is formed from a synthetic resin sheet, and is provided with an engaging means for holding the state of covering the fruit by the elastic restoring force of the synthetic resin. The sunshade shape with respect to can be held without using any special fastening means.

  Hereinafter, a sunscreen for fruits according to an embodiment of the present invention (hereinafter simply referred to as “sunscreen”) will be described with reference to FIGS. Here, the fruit is a vegetable cultivated on the ground G, such as a melon, a watermelon, a seaweed, or a winter rice cake.

  FIG. 1 is a plan view showing a use state in which a cover portion of a sun hood showing an embodiment of the present invention is opened, FIG. 2 is a perspective view from above while closing the cover portion so as to cover fruits, and FIG. 3 is a sun hood. FIG. 4 is a schematic cross-sectional view showing the state of use, and FIGS. 5 and 6 are partially enlarged cross-sectional views of the cover portion.

  As shown in these drawings, the sunshade 1 is composed of a single synthetic resin sheet. This sun cover 1 is a cover 3 that covers the fruit 2 on its side and above by curving against the elasticity of the synthetic resin so that it protrudes sideways from both sides in the width direction of the bottom 3 and the bottom 3 placed on the fruit 2 The parts 4 and 5 are integrally provided.

  In the unfolded state of the sheet, the bottom 3 is formed in a rectangular shape in plan view. Each cover part 4 and 5 is formed in the substantially trapezoid of symmetrical shape, respectively. In the sheet, the bottom (upper base) on the short side of the trapezoid is continuously provided so as to coincide with the length in the longitudinal direction A of the bottom 3.

  The height of the trapezoid in each of the cover portions 4 and 5 is raised so that both the cover portions 4 and 5 are curved from the bottom portion 3, and the end portions 6 and 7 (the lower bottom portion of the trapezoid, which is the longitudinal direction of the sheet) (The end of the width direction B side, which is a direction orthogonal to A)) at a position above the bottom 3 so that it can cover the top of the fruit 2 of a general size without touching it. Is set. Each of the end portions 6 and 7 is formed in a substantially rectangular shape that is long in the longitudinal direction A in plan view.

A plurality of thin and linear thin portions 10 are formed in the middle of the upper surfaces of the cover portions 4 and 5 so as to be along the longitudinal direction A as fragile portions as compared with other portions. The thin portions 10 are formed at regular intervals in the trapezoidal height direction, and are formed over the entire length in the longitudinal direction of the cover portions 4 and 5. For example, the thin portion 10 is formed thin so as to crush the sheet (see FIG. 5).
In addition, the hypotenuses 4a and 5a in the trapezoid of the cover parts 4 and 5 are curving so that it may protrude slightly in the longitudinal direction A.

  The sun cover 1 is covered with the elastic restoring force of the covering parts 4 and 5, that is, the elastic restoring force of the synthetic resin sheet in a state where the end parts 6 and 7 of the covering parts 4 and 5 are overlapped. Locking means for holding the curved state of the portions 4 and 5 is provided. The locking means is formed integrally with the end portions 6 and 7 of the cover portions 4 and 5.

  At the end portions 6 and 7 of the cover portions 4 and 5, stepped surfaces 14 and 15 along the width direction B are formed on the end sides 12 and 13. The stepped surfaces 14 and 15 are formed at substantially the center in the longitudinal direction A of the end sides 12 and 13. Due to the stepped surfaces 14, 15, the end sides 12, 13 of the end portions 6, 7 of the covering portions 4, 5 are parallel to the concave sides 16, 17 and convex sides 20, 21 along the longitudinal direction A Have The concave sides 16 and 17 and the convex sides 20 and 21 at the end portions 6 and 7 of the cover portions 4 and 5 are formed at opposite positions in the longitudinal direction A (symmetric positions with respect to the longitudinal direction center).

  Here, the configuration of the locking means will be described. The locking means includes cut holes 22 and 23 formed in the end portions 6 and 7 and insertion pieces 24 and 25 inserted into the cut holes 22 and 23. That is, the locking means is provided in both the first cover portions 4 and 5 and the other cover portions 4 and 5. In other words, the cover parts 4 and 5 are provided in pairs in the longitudinal direction A.

  The cut holes 22 and 23 are arranged so as to be displaced from the convex sides 20 and 21 of the end portions 6 and 7 toward the bottom portion 3. In this case, each of the cut holes 22 and 23 is formed in a rectangular shape that is long in the longitudinal direction A.

  The insertion pieces 24 and 25 are formed on the concave sides 16 and 17 of the end portions 6 and 7 so as to protrude outward in the width direction B. Each insertion piece 24, 25 is formed in a substantially rectangular shape, and the length in the longitudinal direction A is set slightly smaller than the length in the longitudinal direction of the cut holes 22, 23. The corners 24a and 25a of the insertion pieces 24 and 25 are inclined so that they can be easily inserted into the cut holes 22 and 23.

As described above, it is formed from a single synthetic resin sheet, and a polystyrene resin foam sheet is particularly preferable. The density is, for example, 0.03 to 0.15 g / cm ³ (preferably 0.04 to 0.10 g / cm ³ ), and the thickness is, for example, 0.5 to 8 mm (preferably 1.0 to 5 mm).

  Furthermore, in order to make the sheet difficult to break against external force, it is preferable to add rubber. For example, a styrene / butadiene / styrene block copolymer is preferred as the rubber. This styrene / butadiene / styrene block copolymer is more preferable because it is particularly excellent in compatibility with polystyrene as compared with other rubbers. The sheet is preferably formed to the above thickness while being compressed in the thickness direction. By doing so, the density becomes high and it becomes difficult to break. In addition, by using a polystyrene resin foam sheet, the sheet can be provided at low cost.

  The sun cover 1 having the above-described configuration is used so that the fruit 2 is cultivated so that the fruit 2 is placed on the bottom 3 and both sides and the upper side of the fruit 2 are covered with the cover parts 4 and 5. Here, the procedure for assembling the sunshade 1 will be described. In addition, in FIG. 1 thru | or FIG. 3, the example in the case of deriving the vine 2a of the fruit 2 in the longitudinal direction A of the sunshade 1 is shown.

  In this case, the worker H lays down the fruit 2 so that the vine 2a is in the longitudinal direction A so that the thin-walled portion 10 formed in the covering portions 4 and 5 becomes the upper surface in the sun cover 1 (cover). It puts on the bottom part 3 as a state. By placing the fruit 2 on the bottom 3, the weight of the fruit 2 acts on the sun cover 1, and the sun cover 1 is not easily blown by wind after assembling the cover parts 4 and 5 as shown below.

  Subsequently, the cover portions 4 and 5 are bent in the width direction B so as to rise upward against the elasticity of the cover while utilizing the weight of the fruit 2. At this time, although the cover has elasticity, a plurality of thin portions 10 are formed in the cover portions 4 and 5, respectively. , 5 are easily bent.

Then, the worker H causes the end portions 6 and 7 of the cover portions 4 and 5 to overlap each other, and the cover portions 4 and 5 are locked by the locking means. That is, while the end portions 6 and 7 of the cover portions 4 and 5 are overlapped vertically, for example, the insertion piece 24 of one cover portion 4 is inserted into the cut hole 22 of the other cover portion 5 from below, The insertion piece 25 of the cover portion 5 is inserted into the cut hole 23 of one cover portion 4 from above.
At this time, since the insertion pieces 24 and 25 are formed with corners 24a and 25a that are notched so as to be inclined, the insertion pieces 24 and 25 can be easily inserted into the cut holes 22 and 23, respectively.

  Then, when the operator H removes his / her fingers from the sun cover 1, the sheet inherently has elasticity, so that the cover 4, 5 generates an elastic restoring force that returns to the original sheet shape. (See arrows C1 and C2 in FIG. 6). However, since the insertion piece 24 is inserted into the notch hole 22 and the insertion piece 25 is inserted into the notch hole 23, the upper surface 24b of the insertion piece 24 and the peripheral wall of the notch hole 22 are brought into contact with the elastic restoring force. The corner 4 (or the upper surface of the end 7 of the other cover 5), the upper surface 25b of the insertion piece 25, and the peripheral wall corner of the cut hole 23 (or the upper surface of the one cover 24) come into contact with each other. , 5 covers the fruit 2 on its side and top, and the sun covering state is maintained.

That is, the insertion pieces 24 and 25 are locked in the cut holes 22 and 23 by the elastic restoring force between the cover portions 4 and 5, respectively, and the sun protection state of the cover portions 4 and 5 is maintained. In this way, the sun covering state can be maintained by using the elastic restoring force of the synthetic resin without using any special fastening means such as a stepper.
In other words, the sunshade state refers to the posture of the sunshade 1 that can prevent the sunburn of the fruit 2 by forming a cylindrical body with the bottom part 3 and the cover parts 4 and 5 and storing the fruit 2 therein. It is.

  Since the insertion pieces 24 and 25 and the cut holes 22 and 23 are provided in pairs in the longitudinal direction A, the sun covering state can be securely held by that amount, and a pair of the insertion pieces and the cut holes Even if the lock is released, it is possible to maintain the sun protection state by locking the remaining insertion piece and the cut hole.

  Moreover, since the insertion direction of each insertion piece 24 and 25 to the notch holes 22 and 23 is opposite in the up-and-down direction, it is locking force by the insertion piece 24 and the notch hole 22, and the insertion piece 25 and the notch hole 23. The directions of the vectors will be different. Therefore, it is easy to withstand wind force in a plurality of directions and maintain a sunshade state.

  Furthermore, since the longitudinal direction A of the bottom 3 is set smaller than the longitudinal direction A of the covers 4 and 5, the area of the bottom 3 is significantly smaller than the areas of the covers 4 and 5. Since the sunscreen 1 becomes difficult to move and the area of the fruit 2 is less likely to move, the posture of the fruit 2 is easily stabilized in the sunscreen 1.

Moreover, since the sunshade 1 is formed from a synthetic resin, it does not deteriorate even when exposed to wind and rain, can protect the fruit 2 in the long term, and has low permeability to water, etc. It is possible to avoid exposure to unnecessary moisture.
In addition, since the sheet is a foaming synthetic resin, it has excellent heat insulating properties, and since it is white and opaque, it can block unnecessary sunlight, so that it is possible to cultivate fruits 2 with higher commercial value. .

  This invention is not limited to the said embodiment, For example, according to the kind of fruit 2 to grow, the structure of the sunshade 1 can be changed suitably. That is, the fruit 2 to be cultivated in the above embodiment is such that the vine 2a is led out in the longitudinal direction A, but the fruit 2 needs to be cultivated with the vine 2a facing upward. The case where it is preferable to turn the vine 2a upward during the cultivation can be considered.

  In such a case, the sunshade 1 is provided with a lead-out hole 30 for leading out the vine 2a. For example, the lead-out hole 30 is preferably formed in a state where the end portions 6 and 7 of the cover portions 4 and 5 are overlapped. In this embodiment, the imaginary lines in FIGS. 1 to 3 show the recesses 31 and 32 that become the lead-out holes 30 at the end portions 6 and 7. These concave portions 31 and 32 are formed at substantially the center in the longitudinal direction A of the end sides 12 and 13 of the end portions 6 and 7. The lead-out hole 30 is formed in a state where the end portions 6 and 7 are overlapped.

  According to this configuration, as shown in FIG. 4, the vine 2 a can be cultivated so as to be led out from the lead-out hole 30 corresponding to the type of the fruit 2, and the fruit 2 and the sunshade 1 are integrated. As a result, the fruit 2 is stabilized in the sunshade 1.

  The shapes of the insertion pieces 24 and 25 and the shapes of the cut holes 22 and 23 are not limited to the above embodiment. For example, as shown in FIG. 7, the shape of the insertion pieces 24 and 25 is such that the head portion 35 and a neck portion 36 that is narrower than the head portion 35 are connected in the width direction B, and the cut holes 22 and 23 are elongated. A configuration in which the portion 37 and the short portion 38 are continuously provided in the width direction B is also possible.

  According to this configuration, the insertion pieces 24 and 25 are inserted from the long portions 37 of the cut holes 22 and 23, and the neck portions 36 of the insertion pieces 24 and 25 are locked to the short portions 38 of the cut holes 22 and 23. In this case, since both the cut holes 22 and 23 and the insertion pieces 24 and 25 have stepped portions, the locking force of the both increases correspondingly, and the sun covering state of the sun covering 1 can be reliably maintained. .
