Description

  The present invention relates to a holder for a tree protector that is used on seedlings in order to promote the growth of seedlings and planted trees and to prevent food damage caused by animals such as deer, moths, and moths. is there.

  Conventionally, when seedlings are planted, 30% to 9% due to damage caused by eating deer, pods, etc., by eating shoots, leaves or stems, or by sacrificing seedlings to the growth of weeds and covering damage due to lack of light. There was a problem that it died.

  Therefore, in recent years, a so-called tree protector with a translucent resin material in a cylindrical shape is covered from above the seedlings, and is fixed to a support such as a splint that has been driven into the ground with a tying tool such as a string or a band to prevent food damage. doing. In addition, it protects the seedlings from the wind and promotes growth.

  Here, as shown in FIG. 9A, the tree protector 1 is made of a transparent or translucent resin sheet wound in a roll shape, and is continuously provided on the six side surfaces 2a to 2f and the one side surface 2a. And an adhesive margin 3 for fixing to the side surface 2f at the other end. A cut portion 4 having a half cut (substantially half the thickness) is provided at a boundary portion between the adjacent side surfaces 2 a to 2 f and the adhesive margin 3. As shown in FIG. 9B, the tree protector 1 formed in this unfolded state is after the side surface 2a is bent between the side surfaces 2b in a state where a predetermined adhesive is applied to the glue margin portion 3. By bending the side surface 2e with respect to the side surface 2d, the adhesive margin 3 is adhered to the side surface 2f and formed in a folded state suitable for conveyance.

  As shown in FIG. 10, the binding tool 5 includes a flexible band 6, and a locking portion 7 having an elastic locking piece is provided at one end of the band 6. A so-called band clip made of resin having a plurality of discontinuous locking grooves 8 on one surface is widely used.

  However, there is a problem that the tree protector 1 is deformed by the pressure of the snow (snow pressure) when snow falls in the winter and becomes unusable in the worst case. And if a tree protector deform | transforms to an unusable state, the inconvenience of damaging an internal seedling will arise.

  The holder 10 of the tree protector 1 of the present invention is for preventing such a problem, and the prior art document information includes the following.

Design Registration No. 10910155

  This patent document describes a regular hexagonal cylindrical holder 10 having an inner shape substantially the same as the outer shape of the tree protector 1 as shown in FIG. 11 for the purpose of suppressing deformation of the tree protector 1. Has been. In order to improve the assembly workability, the holder 10 is provided with an annular rib 11 extending outward at one end opening portion thereof.

  When the tree protector 1 is erected using the holder 10, the folded tree protector 1 is first spread and the holder 10 is put on the outside. Next, the tree protector 1 is placed on the seedling from above, and the support column 9 is erected on the ground so as to be adjacent. Thereafter, the band 6 of the binding tool is inserted between the holder 10 and the tree protector 1 so that the band 6 is inclined with respect to the support column 9 and the tip thereof is inserted into the hole of the locking portion 7. Let Then, the tree protector 1 is held by the support column 9 by fastening the band 6 to the locking portion 7 by tightening with a predetermined force.

  However, when the tree protector 1 is held by the support 9 via the holder 10, the band 6 of the tying member 5 is twisted and inclined. Then, only one edge of the band 6 is pressed against the end edge of the holder 10. Therefore, particularly when the place of use is a mountainous area where the wind is strong, the tree protector 1 is swung by receiving the wind, so that stress concentrates on the pressure contact portion and the binding tool 5 is broken. .

  Further, in the conventional holder 10, there is a problem that the holder 10 is detached from the tree protector 1, although it is bound to the support column 9 by the binder 5. This is because, in the holder 10, the twisting degree of the band 6 is increased, so that the angle formed with respect to the column 9 is widened, and the contact area with respect to the column 9 is reduced. As a result, the locking force to the column 9 by the binding tool 5 is reduced. The holder 10 receives the wind blown up by the annular rib 11 of the holder 10, so that the holder 10 moves along the tree protector 1 or the tree protector 1 swings the holder 10. Move gradually. If it does so, it is thought that it arises because the binding tool 5 moves interlockingly with the holder 10, although the protrusion 9 is formed in the support | pillar 9. As shown in FIG.

  This invention is made in view of the conventional problem, and makes it a subject to provide the holder which can prevent reliably the fracture | rupture of a binding tool and the drop-off | omission from a tree protector.

  In order to solve the above-mentioned problems, the tree protector holder of the present invention is fitted into the outer periphery of a tree protector in which a transparent or translucent resin sheet is formed into a cylindrical shape, and is bound to a column adjacent to the tree protector with a binding tool. Accordingly, the holder that holds the tree protector in a cylindrical shape and supports the side of the support column is formed of an annular member having an inner shape substantially the same as the outer shape of the tree protector, and the binding tool is inserted into the edge of the holder. It is set as the structure which provided the notch part to perform.

Specifically, in the annular peripheral wall, the first cutout portion is provided at the upper end edge, and the second cutout portion is provided at the lower end edge at a predetermined interval in the lateral direction from the first cutout portion.
Further, it is preferable that the tree protector and the holder have a polygonal cross section, and the first and second cutout portions are provided on at least one wall portion constituting the peripheral wall. However, considering the workability when covering the seedling with the tree protector assembled with the holder, or the workability when standing uprights, it is preferable to provide the upper and lower edges of all the wall portions.

  In the installation state of the tree protector using this holder, as in the conventional case, the band of the binding tool is inserted between the holder and the tree protector, and both ends thereof are turned to the support and locked by the locking portion. As a result, the band of the binding tool is inclined obliquely. However, since the holder of the present invention is provided with a notch for inserting the band of the binding tool, only one edge of the band is attached to the edge of the holder by binding with the binding tool through the notch. The band is not brought into the pressure contact state, and the band can be brought into surface contact with the edge of the notch. As a result, it is possible to disperse the frictional force generated when the tree protector swings in response to the wind, and it is possible to suppress the band of the binding tool from breaking.

  Moreover, since the band of a binding tool hardly twists by binding through a notch part, the angle | corner made with respect to the support | pillar 9 can be made small and the contact area with respect to a support | pillar can be increased. As a result, it is possible to increase the locking force of the tying member 5 to the support column 9, so that even if a force that moves the holder along the tree protector acts, the holder can be surely moved gradually. Can be prevented.

  In this holder, it is preferable to provide two sets of the first and second cutout portions on the wall portion. In this way, since the directionality when assembling the binding tool can be eliminated, it is possible to efficiently perform the binding work without being affected by conditions such as the work space being narrow or the operator's dominant arm. it can.

  Moreover, it is preferable that the said notch part consists of a groove | channel notched in the V shape, and each inclined side of a 1st and 2nd notch part is provided substantially parallel. If it does in this way, twist of a binding tool can be controlled certainly.

  In the holder of the tree protector of the present invention, it is possible to prevent only one edge of the band from being in pressure contact with the end edge of the holder by binding with the binding tool through the notch. Therefore, it can suppress that the band of a binding tool fractures. Since the locking force with respect to the support | pillar by a binding tool can be increased, it can prevent falling from a tree protector.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 and 2 show a holder 20 of a tree protector 1 according to an embodiment of the present invention. The holder 20 holds the same tree protector 1 as shown in FIGS. 9A and 9B in a cylindrical shape and is erected on the side of the support column 9 via the binding tool 5.

  The holder 20 is made of a transparent or semi-transparent resin, similar to the tree protector 1, and is slightly different from the tree protector 1 having a regular hexagonal cylindrical shape as shown in FIGS. 2 (A), (B), and (C). It consists of a large annular member. Specifically, the holder 20 has a regular hexagonal cylindrical shape including six wall portions 21a to 21f constituting a peripheral wall, and is substantially the same as the outer shape of the tree protector 1 by the inner surfaces of the wall portions 21a to 21f. It is comprised so that the same internal shape may be made. 2B and 2C, the thin line represents the ridge of the curved portion.

  Each of the wall portions 21a to 21f is provided with a pair of first cutout portions 22a and 22b made of V-shaped grooves on the upper edge and a second V-shaped groove on the lower edge. A pair of notches 23a and 23b are provided. Here, as for these, the notch parts 22a and 23a and 22b and 23b which are located diagonally make a pair (one set), respectively. In the present embodiment, the first cutout portions 22a and 22b and the second cutout portions 23a and 23b are located on both sides of the wall portions 21a to 21f with the center line L extending in the vertical direction extending from the both end openings. Is provided. In other words, the two sets of notches 22a, 23a and 22b, 23b positioned at a predetermined interval in the lateral direction are provided symmetrically with respect to the center line L.

  And two sets of notches 22a and 23a and 22b and 23b are provided so that each inclination side may be located in parallel. Here, in each of the notches 22a, 22b, 23a, 23b, the angle α between the pair of inclined sides and the lateral interval W depend on the outer diameter of the upright column 9 and the band 6 of the binding tool 5 The band 6 is set so as to come into surface contact with the inclined side of the notch in a state where the support 9 is turned and bound.

  Next, the installation work of the tree protector 1 using the holder 20 will be specifically described.

  First, the tree protector 1 in the folded state shown in FIG. 9B is spread, and the holder 20 is put on the outside. At this time, the number of holders 20 that are externally fitted to one tree protector 1 is changed according to the total length of the tree protector 1. Next, the plant protector is covered with the tree protector 1 from above, and the column 9 is erected on the ground so as to be adjacent to each other.

  Thereafter, the band 6 of the tying member 5 is inserted between the holder 20 and the tree protector 1 so that the band 6 is obliquely inclined with respect to the support column 9, and the tip thereof is inserted into the hole of the locking portion 7. The band 6 is locked to the locking portion 7 by being inserted and tightened with a predetermined force. At this time, the band 6 of the tying member 5 is inserted into the pair of notches 22a and 23a or 22b and 23b.

  As shown in FIG. 1, in this installation state, the band 6 of the tying member 5 is inclined obliquely as in the prior art. However, the holder 20 of the present invention is provided with two sets of V-shaped cutout portions 22a, 22b, 23a, and 23b, and the band 6 of the binding tool 5 is bundled through the one set. In addition, only one edge of the band 6 does not come into pressure contact with the end edge of the holder 20. That is, the band 6 of the tying member 5 is in surface contact with the inclined edges of the notches 22a and 23a or 22b and 23b. As a result, it is possible to disperse the frictional force generated by the swinging of the tree protector 1 in response to wind, and the band 6 of the tying member 5 can be prevented from breaking.

  Moreover, since there is no part (annular rib 11) which protrudes outside like the conventional holder 10, the holder 20 does not move along the tree protector 1 due to the influence of the wind. It can be lost. However, in the case where the dropout of the holder 10 is a movement caused by the swinging of the tree protector 1, the same can occur in the holder 20 of the present embodiment. However, in the holder 20 of the present embodiment, the band 6 of the binder 5 is hardly twisted by binding through the notches 22a, 23a or 22b, 23b. Therefore, as shown in FIGS. 3 (A) and 3 (B), the angle formed by the band 6 with respect to the column 9 is smaller than the angle β1 formed by the conventional holder 10 as compared with the angle β2 formed by the holder 20 of the present invention. . As a result, since the contact area of the band 6 with the support 9 can be increased, the locking force of the binding device 5 to the support 9 can be increased. Moreover, as the angle β2 formed can be reduced, the locking force to the protrusions of the support column 9 can also be increased. Therefore, even if the force that moves the holder 20 along the tree protector 1 acts, it is possible to reliably prevent the holder 20 from being moved by the binding force to the support column 9 by the binding tool 5. Therefore, whatever the specific factor is, it is possible to reliably prevent the holder 20 from falling off the tree protector 1.

  Furthermore, in this embodiment, since two sets of notches 22a, 22b, 23a, and 23b are provided in each of the wall portions 21a to 21f, work for covering the seedling with the tree protector 1 to which the holder 20 is assembled. Or the workability at the time of erecting the support column 9 can be improved. Moreover, since the directionality when assembling the binding tool 5 can be eliminated, it is possible to efficiently perform the binding work without being affected by conditions such as a narrow work space or the operator's dominant arm.

  Note that the holder 20 of the tree protector 1 of the present invention is not limited to the configuration of the above-described embodiment, and various modifications can be made.

  For example, in the embodiment described above, two sets of notches 22a, 23a and 22b, 23b are provided in all the walls 21a to 21f constituting the holder 20, but as shown in FIG. 4, one wall 21a is provided. You may provide only. Moreover, as shown in FIG. 5, you may provide only in two wall part 21a, 21d which opposes. Furthermore, as shown in FIG. 6, you may provide only in every other wall part 21a, 21c, 21e.

  Moreover, as shown in FIG. 7, it is good also as a structure which provided only one set of notches 22a and 23a in each wall part 21a-21f. Of course, in the modified examples shown in FIGS. 4 to 6, only one set of notches 22a and 23a may be provided.

  Further, in the above embodiment, in order to hold the hexagonal tubular tree protector 1, the holder 20 is made of a similar hexagonal tubular ring member, but as shown in FIGS. 8 (A) and 8 (B). In the case of the tree protector 1 in which the corrugated resin sheet is cylindrical, the holder 20 is also cylindrical, and notches 22a, 22b, 23a, and 23b are formed on the upper and lower edges of the peripheral wall. Of course, the number of notches may be one set or two or more.

  Furthermore, in the said embodiment and each modification, although the external shape of the tree protector 1 and the holder 20 was made into the same shape, the external shape of the holder 20 is different and only an internal diameter is the same as the external shape of the tree protector 1. You may do it. Moreover, the holder 20 is not limited to a transparent or translucent resin, and may be opaque or may be formed of a material other than a resin.
