In the above-described conventional self-supporting seedling supporter, it is necessary to push the stem into the accommodating portion by pressing the stem toward the introduction portion of the pair of horizontal arms. There is a difficulty in getting out of the containment section. Moreover, once attached to a seedling, it is not easy to remove.
Therefore, the present invention provides a self-supporting supporter for young seedlings that can be easily attached to and detached from the stems of the seedlings, and can easily release the stems without damaging the stems when the stem diameter increases with growth. It is aimed.

Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
In order to solve the above-mentioned problems, the seedling self-supporting support 1 of the present invention is integrally formed of an elastic synthetic resin, and is a rod-shaped support 2 that is planted on the soil so as to follow the stem of the seedling. A retaining portion 3 connected to the upper end of the portion 2 and capable of gripping and releasing the stem of the seedling P is provided. The retaining portion 3 is configured to open and close a pair of first and second gripping portions 4 and 5 that are curved so as to face each other so that the stem of the seedling P can be held. Extends in the opposite direction to the gripping portions 4 and 5 continuously to the bendable hinge portion 6 that connects the base end portions of the gripping portions and the base end portions of the first and second gripping portions 4 and 5, respectively. A first and second pair of knobs 7 and 8 that act to open between the first and second gripping parts 4 and 5 when pressed in the closing direction are provided. The first and second gripping portions 4 and 5 are provided with engaging portions 9 and 10 at their tip portions that snap-engage with each other when pressed in a closing direction. The engaging portions 9 and 10 are set to have an engaging force so that the first and second knob portions 7 and 8 are pressed in the closing direction to be disengaged from each other.
One of the engaging portions 9 and 10 is an engaging protrusion that protrudes to the inside of the curve of the grip portion 4, and the other is an engaging protrusion that protrudes to the outside of the curve of the grip portion 5, and the first and second inclined surfaces 9 a, respectively. , 9b, 10a, 10b. The first inclined surfaces 9a and 10a are configured to bend each other so that the distal end portion of one gripping portion 5 is bent toward the inside of the curve and the distal end portion of the other gripping portion 4 is bent toward the outside of the curve when the gripping portions 4 and 5 are closed. To slide. The second inclined surfaces 9b and 10b are in contact with each other when they are engaged with each other, and when the gripping portions 4 and 5 are opened, the tip of one gripping portion 5 is brought into the inside of the curve, and the tip of the other gripping portion 4 Are slid relative to each other to bend out of the curve.

  According to the self-supporting support device 1 of the present invention, the attachment of the young seedling P to the stem opens the gap between the gripping portions 4 and 5 by pinching with a fingertip so as to close the picking portions 7 and 8 as necessary. After introducing the stem between the two, the gripping parts 4 and 5 can be easily picked by the fingertips so as to close the gripping parts 4 and 5 and the engaging parts 9 and 10 can be engaged with each other. At the time of removal, if the fingertips are used to close the knobs 7 and 8, the force that opens between the gripping parts 4 and 5 can overcome the engagement force of the engagement parts 9 and 10, thereby releasing the engagement. The gripping portions 4 and 5 are opened, and the removal operation can be performed without damaging the stem. When the stem diameter increases with the growth of the seedling, the engagement portions 9 and 10 are disengaged and the stem is released, so that the stem is not damaged.

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, a self-supporting support 1 is integrally formed of an elastic synthetic resin such as polypropylene, and is a rod-shaped support 2 that is planted on the soil S along the stem of the seedling P, and the upper end of the support 2. And a retaining portion 3 extending substantially at a right angle.

  The retaining portion 3 is configured to open and close the first and second pair of gripping portions 4 and 5, a bendable hinge portion 6 that couples the base end portions of the gripping portions 4 and 5, and the gripping portions 4 and 5. A first and a second pair of knobs 7 and 8 are provided. The holding parts 4 and 5 are curved so as to face each other so that a space for holding the stem of the seedling P can be formed therebetween. The hinge portion 6 flexibly connects the base end portions of the grip portions 4 and 5 so that the pair of grip portions 4 and 5 can be opened and closed. The first and second pairs of knobs 7 and 8 extend in the opposite direction to the grips 4 and 5, respectively, in succession to the base ends of the grips 4 and 5. The knobs 7 and 8 act so as to open between the first and second gripping parts 4 and 5 when pressed in the closing direction. In addition, the holding | maintenance part 3 is in the state of FIG. 3 with the holding parts 4 and 5 opened in a natural state.

  The gripping portions 4 and 5 are provided with engaging portions 9 and 10 at their distal ends, which are snap-engaged with each other when pressed in the closing direction. The engaging force of the engaging portions 9 and 10 is set so that the engaging portions 9 and 10 are disengaged from each other when the first and second knob portions 4 and 5 are pressed in the closing direction.

  One engaging portion 9 is an engaging protrusion that protrudes to the inside of the curve of the grip portion 4, and the other engaging portion 10 is an engaging protrusion that protrudes to the outside of the curve of the grip portion 5.

  The engaging protrusions 9 and 10 include first and second inclined surfaces 9a, 9b, 10a, and 10b, respectively. The first inclined surfaces 9a and 10a are configured to bend the distal end portion of one gripping portion 5 toward the inside of the curve and the distal end portion of the other gripping portion 4 toward the outside of the curve when the gripping portions 4 and 5 are closed. Slide against each other. As shown in FIG. 4, the second inclined surfaces 9b and 10b come into contact with each other when they are engaged with each other, and when the gripping portions 4 and 5 are released from this state, the tip of one gripping portion 5 is curved. The other gripping part 4 slides inward so as to bend the tip part of the other gripping part 4 to the outside of the curve.

  In use, as shown in FIG. 1, the support 2 is pierced into the soil S beside the young seedling P so as to be along the young seedling P. The holding parts 4 and 5 are directed toward the stem of the seedling P, and the stem of the seedling P is received between them. At this time, if necessary, the knobs 7 and 8 can be picked so that the gap between the gripping parts 4 and 5 can be further opened. When the stems are received in the gripping portions 4 and 5, when the gripping portions 4 and 5 are pinched from the outside to close each other, the tip portions of the gripping portions 4 and 5 are bent due to the sliding of the inclined surfaces 9a and 10a. The engaging protrusions 9 and 10 are snap-engaged to hold the stem between the gripping portions 4 and 5. When removing the support 1 from the young seedling P as necessary, the pair of knobs 7 and 8 are operated from the outside so as to close each other. In this way, the force to open between the gripping portions 4 and 5 is superior to the engagement force between the engaging projections 9 and 10, and the tip portions of the gripping portions 4 and 5 are bent due to sliding of the inclined surfaces 9b and 10b. Since the mating protrusions 9 and 10 are disengaged and the holding portions 4 and 5 are opened, the support 1 can be removed from the seedling P without damaging the stem.

  Thereafter, when the seedling grows and the stem diameter increases, the engagement between the engaging portions 9 and 10 is released by itself and the gap between the gripping portions 4 and 5 is pushed open.
