Description

  The present invention relates to a plant stalk-inducing tie that attracts a plant stalk in a direction in which the plant stalk extends.

Generally, as stems of seedlings of plants such as cucumber and tomato grow upward, they grow upward and the stems become thick. When the weight of a plant increases as it grows, the stem may be broken by its own weight and it may not be able to grow in a desired direction.
As an instrument for attracting a plant stem in a desired direction, a plant stem-induced binding device made of plastic is used (for example, Patent Document 1). The plant stem inducing binder is attached to a vertically or horizontally stretched string and attracts the direction in which the plant stem extends.

  The plant stem inducement binding device of Patent Document 1 closes between the first clamping piece and the second clamping piece rotatably supported by each other in the middle portion so as to open and close one end side, and one end of these clamping pieces And a spring member biased in a direction. And the first pinching piece and the second pinching piece are an arc-like stem support part which surrounds and restrains around a stem of a plant, an operation part (picking part) which opens and closes between these stem support parts, and a stem support A pivoting portion (pivot support portion) provided between the control unit and the operation portion, and a string holding portion (string stop portion) provided between the pivoting portion and the stem support portion for holding the hanging string doing.

In this plant stalk inducing binding device, the first sandwiching piece is formed in an arc shape surrounding an outer periphery exceeding a half circumference around the stem of the plant, and the second sandwiching member is formed in an arc shape surrounding an outer periphery less than a half periphery around a stem A locking claw is formed on at least one of the operation portions of the holding pieces to lock the sling wound around the operation portion.
In this plant stalk inducing binding device, the second holding piece is formed in an arc shape surrounding the outer periphery less than a half circumference around the stem, and the tip of the first holding piece is attached to the tip of the second holding piece. By making one clamping piece arc-shaped, the tip is butted at a position deviated from the center line of the opening angle of both stem support portions. Then, the stem of the plant is supported by the stem support portion of the first sandwiching piece, and no load from the stem is applied to the tip of the stem support portion. Therefore, it is difficult to apply a load in a direction to open the tip portions of the stem support portion, and the stem of the plant can be supported by the plant stem invitation binding device.
Furthermore, in this plant stalk inducing binding device, the hanging cord is wound around a locking claw provided on the operation unit and locked. By the suspension cord being locked to the locking claw, it is possible to prevent the plant stem inducing and binding binder from being slipped off from the suspension cord even when the cord sandwiching parts are opened due to the load from the stem.

The usage method of the plant stalk invitation binding device 1 which concerns on this embodiment is demonstrated with reference to FIG.
The plant stalk invitation binding device 1 is fixed to a hanging strap and is used by being suspended. Specifically, the plant stem inducement binding device 1 is operated such that the operation unit 3 approaches, and the tip end portions of the stem support portions 2 and the string holding portions 5 are opened. Then, a hanging cord stretched along the stem of the plant is inserted between the cord sandwiching portions 5, and the stem of the plant is inserted into the inside of the stem supporting portion 2. Then, the operation part 3 is operated to separate, and the hanging cord is held by the cord holding part 5, and the stem of the plant is surrounded by the stem supporting part 2. Under the present circumstances, as shown to Fig.5 (a), the hanging cord is pinched by the cord holding part 5 (tooth part 12).
Next, as shown in FIGS. 5 (b) and 5 (c), the hanging strap on the upper side of the hanging strap sandwiched by the string gripping portion 5 is brought into contact with the string winding members 31, 21 and wound. It winds around the winding parts 30 and 20 along the attachment grooves 34 and 24. And as shown in FIG.5 (d), a suspension cord is contact | abutted to the string guidance groove 38, and a suspension cord is guide | induced to the back side of the front-back direction X. As shown in FIG.

Next, the effect of the plant stalk invitation binding device 1 which concerns on this embodiment is demonstrated.
When the weight of the plant increases and the load applied to the stalk support 2 increases as the plant grows, or when the diameter of the stalk becomes larger than the inner diameter of the stalk support 2, the pivoting portion 4 or the string is pinched A force is applied to move the part 5 in the opening direction.
A hanging strap is wound around the winding parts 20 and 30, and therefore, the plant stem inducing and quoting binding device 1 according to the present embodiment has a force to operate in the direction in which the rotating part 4 and the cord holding part 5 open. , The operation in the direction in which the string holding unit 5 opens is restricted. Therefore, even when a load is applied from the stem of the plant to the stem support portion 2 in the direction in which the string sandwiching portion 5 opens, the motion in the direction in which the string sandwiching portion 5 opens can be reliably prevented.

When a large load is applied to the stem support portion 2 from the plant in a state of being locked to the hanging strap, the plant stem inducing and binding device 1 uses the string guiding portion 25 (or the winding portions 20 and 30) as a fulcrum. The stalk support 2 side sags, and a pulling force to the lower side in the height direction Y is applied to the plant stalk inducing binding device 1. Since this force is also applied to the hanging strap, the hanging strap is pulled downward in the height direction Y. When the sling is pulled downward, tightening of the sling wound around the winding portions 20 and 30 and the string guiding portion 25 becomes strong.
Therefore, even when a large load is applied from the stem of the plant in the direction in which the string holding unit 5 opens, the string holding unit 5 can be reliably prevented from opening.

Moreover, in the plant stalk inducement binding binder 1 of the present embodiment, the string guiding part 25 is provided on the rotating part 4, and the hanging cord is wound on the winding parts 20 and 30, Be touched. By the suspension cord being in contact with the cord guiding part 25, the balance of the plant stem inducing and binding binder 1 can be maintained.
Therefore, the plant stalk invitation binding device 1 can be stably hung on the hanging cord.

In the plant stalk inducing and binding binder 1 of the present embodiment, the wound portions 20 and 30 are adjacent to each other in a state where the tip end portion 10 is in contact. Therefore, the winding parts 20 and 30 become integral and it becomes easy to wind a hanging cord.
Further, winding grooves 24 and 34 are formed in the winding portions 20 and 30, respectively, and a hanging strap is wound along the winding grooves 24 and 34. Since the winding grooves 24 and 34 are formed, in addition to the ease of winding the hanging strap, the hanging strap wound around the winding grooves 24 and 34 is a locking member 22 constituting the winding grooves 24 and 34. , 32 so that the hanging strap can be prevented from coming off the winding portions 20, 30.

  The plant stem inducing and binding tool 1 is formed on the rotating portion 4 which is closer to the operation portion 3 than the winding portions 20 and 30 and which is substantially at the center in the left-right direction Z. When a large load from the plant is applied to 2, the cable hangs down with the string guiding portion 25 as a supporting point. Then, the plant stem inducing and binding binder 1 can be suspended to the hanging cord without being biased to the right or left in the left-right direction Z.

The plant stem inducement binding binder 1 of the present embodiment is configured by combining the first sandwiching piece 8 and the second sandwiching piece 9 having the same structure as the first sandwiching piece 8, The front and back of the quoted binder 1 have the same structure.
Then, the user can attach the plant stem invitation cable tie 1 to the suspension cord without making a distinction between the front and back of the plant stem invitation cable 1, and the plant stem invitation cable tie to the suspension cord Installation of 1 does not take time.

  The action of the plant stem-inducing tie in the direction in which the tip end portion of the stem support portion or the string holding portion opens is restricted by the biasing force of the spring member. Therefore, conventionally, by using a spring member having a large biasing force, it is prevented that the tip end portion of the stem support portion and the string holding portion are opened. The use of a spring member having a large biasing force requires the user to apply a large force to the operation portion. Furthermore, since a large number of the plant stem-inducing binding devices are attached, a large burden is placed on the user's hand.

The hanging cord is wound around the winding parts 20 and 30, and the plant stalk inducing quotation binding device 1 of the present embodiment can reliably prevent the movement in the direction in which the cord sandwiching part 5 opens. Therefore, it is also possible to use a spring member 7 whose biasing force is smaller than that of a conventional spring member.
Then, the user can attach the plant stalk inducing tie 1 to the hanging cord without putting a heavy burden on the hand.

As described above, the second sandwiching piece 9 constituting the plant stem inducing and binding device 1 according to the present embodiment is obtained by inverting the first sandwiching piece 8 and is the first sandwiching piece 8 and the second sandwiching piece 9 Have the same structure.
Therefore, the 1st clamping piece 8 and the 2nd clamping piece 9 can be produced using the same metal mold | die. In this case, it is not necessary to manufacture a mold for each holding piece, and compared with the case of manufacturing one having different shapes of the first holding piece 8 and the second holding piece 9, the labor and design cost for designing the mold are reduced. it can.

As mentioned above, although this embodiment was described, it is possible not only to deviate from the gist of the present invention, but to select the configuration described in the above embodiment or to appropriately change it to another configuration. .
For example, the position at which the string guiding portions 25 and 35 are provided is not limited to the rotating portion 4 as long as the plant stem inducing and binding binder 1 can be balanced. Moreover, the shape of the winding parts 20 and 30 is not limited to the example shown to this embodiment, For example, you may form in fan shape.
In addition, after a hanging cord is wound around the winding parts 20 and 30, it can also be wound around cord guidance part 25 (35).
