Description

  [Technical Field] The present invention relates to a fixing pin for a plant runner that is used by being stabbed in a medium in order to fix a runner generated from a strain of a vine plant such as a strawberry to the medium.

  Vineyards such as strawberries generate runners from the parent strain to form child stocks, and then repeat the generation of runners from the child strains to form new child strains. The root of is bad. Therefore, conventionally, the runner is pressed against the medium with a generally reverse U-shaped presser made of a synthetic resin so that the root of the offspring is surely brought into contact with the medium and rooting is promoted. As such a runner fixing tool, one described in Patent Document 1 is known. The runner fixing tool includes a pair of arcuate base end portions that can press the runner from above, and extending from both ends of the base end portion so as to be located on both sides of the runner and inserted into the medium. And a round bar-shaped handle portion that protrudes in the opposite direction to the protruding direction of the pair of leg portions from the base end portion, and is integrally formed of synthetic resin. The pair of leg portions are formed in a linear shape that gradually expands from both ends of the base end portion to the middle portion, and are formed in a straight line that is substantially parallel to each other from the middle portion to the distal end.

Japanese Patent Laid-Open No. 11-75569

In the conventional runner fixing device, the leg portion and the handle portion have a rounded and elongated round bar shape. By the way, recently, bark of trees such as crushed cedar bark is used as a growth medium. Such a medium has many hard parts, and in the structure like the conventional fixture described above, the legs cannot be easily pierced into the medium, and even if the medium is pierced into the surface layer part, there is a hard part in the deep part. If there is, there is a problem that it stops there or the legs are deformed and the whole is twisted and cannot be firmly fixed to the medium.
Therefore, the present invention can easily pierce a medium having a non-uniform hardness, such as a cedar skin medium, and having many hard parts without deformation, and can securely fix the runner. It aims to provide a plant runner fixing pin.

Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
The runner fixing pin 1 of the present invention for solving the above problems is integrally formed of synthetic resin, and includes an upper knob portion 2 and a lower leg portion 3. The knob 2 has a flat plate shape having a surface 4 in the thickness direction and a back surface 5 on the opposite side. The leg portion 3 includes a curved connecting portion 6 connected to the lower portion of the knob portion 2 and a pair of embedded legs that are located on both sides in the width direction of the knob portion 2 and extend downward from both end portions of the curved connecting portion 6. 7. The pair of piercing legs 7 includes a straight portion 10 that extends downward in a straight line parallel to each other, and a sharpened portion 11 that continues to the lower end of the straight portion 10. The straight portion 10 is continuous with both ends of the curved connecting portion 6 and extends along the outer edge portion. The straight portion 10 extends vertically inward from the flange portion 12 and extends along the flange portion 12. And a web portion 13 extending in a curved manner along the inside of the curved connection portion 6.

  In the runner fixing pin 1 of the present invention, since the straight portion 10 of the piercing leg 7 is composed of the flange portion 12 and the web portion 13, the strength against bending deformation is high, and the space between the pair of piercing legs 7 is expanded. And can be inserted straight into the medium B. Expansion between the piercing legs 7 is also prevented by the web portion 13 extending to the inside of the curved connecting portion 6. The sharp portion 11 can be easily pierced with respect to the relatively hard medium B.

Embodiments of the present invention will be described with reference to the drawings.
The runner fixing pin 1 is integrally formed of a synthetic resin, and includes an upper knob portion 2 and a lower leg portion 3. As shown in FIG. 9, the runner fixing pin 1 holds a plant runner R between the two piercing legs 7 of the leg 3 in use, and the piercing leg 7 is pierced into the medium.

  The knob 2 has a flat plate shape having a surface 4 in the thickness direction and a back surface 5 on the opposite side. The leg portion 3 includes a curved connecting portion 6 connected to the lower portion of the knob portion 2 and a pair of embedded legs that are located on both sides in the width direction of the knob portion 2 and extend downward from both end portions of the curved connecting portion 6. 7.

  The curved connecting portion 6 has front and back raised surfaces 8 and 9 raised from the front surface 4 and the back surface 5 of the knob portion 2, extends curvedly toward the knob portion 2, and is pinched on the outer side (upper portion) of the curve. It continues to the lower part of part 2.

  The piercing leg 7 includes a straight portion 10 that extends downward in a straight line parallel to each other from both ends of the curved connecting portion 6, and a sharp portion 11 that is continuous with the lower end portion of the straight portion 10.

  The straight portion 10 includes a flange portion 12 and a web portion 13. The flange portion 12 extends along the outer edge portion of the straight portion 10 continuously to both end portions of the curved connection portion 6. That is, the flange portion 12 has front and back surfaces 14 and 15 that are flush with the raised surfaces 8 and 9 of the curved connection portion 6, and is continuous with both ends of the curved connection portion 6 with the same thickness as the curved connection portion 6. . The web portion 13 extends vertically inward from the flange portion 12 and extends along the flange portion 12, and is curved and extends along the inside of the curve of the curved connection portion 6 at the upper end portion.

  The sharp portion 11 includes an inward slope 16 that extends from the lower outer side to the inner lower end of the linear portion 10 so as to obliquely cut the flange portion 12 and the web portion 13. The sharp portion 11 includes a sharp flange portion 18 that is continuous with the flange portion 12 and extends along the edge of the inward slope 16. The sharp flange portion 18 has a slope 17 that converges at the lower end.

  In FIG. 6, when the runner R of the plant is fixed to be in contact with the upper surface of the medium B using the runner fixing pin 1, the runner R is held between the pair of piercing legs 7, and the piercing leg 7 Is inserted into medium B. At this time, when the medium B is made of a relatively hard material such as cedar bark, it is necessary to pierce the piercing leg 7 with a correspondingly strong force. However, the runner fixing pin 1 is subjected to bending stress applied at this time. Can withstand. That is, since the piercing leg 7 has the flange part 12 and the web part 13 which continue to the curved connection part 6 which is thicker than the knob part 2, the strength against bending deformation is high. Further, since the sharp portion 11 is linear with the inner side being perpendicular to the culture medium B and has an inward slope 16 on the outer side, when the medium B is pierced, the space between the pair of piercing legs 7 may be expanded. And can be inserted straight into the medium B. The spread between the piercing legs 7 is also prevented by the web portion 13 that is curved and extends to the inside of the curved connecting portion 6. Since the web portion 13 is also continuous with the sharp portion 11 and the sharp flange portion 18 that is continuous with the flange portion 12 is formed on the outer edge thereof, the sharp portion 11 has high strength and can be inserted into a hard medium without being deformed. be able to. If the spread between the piercing legs 7 can be prevented by only the configuration of the flange portion 12 and the web portion 13 of the straight portion 10 due to the nature of the medium B, an outward slope may be provided inside the sharpened portion 11. Good.
