Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement of scissors for growing plants. The plant growing scissors of the present invention are particularly effective when used for attracting and supporting vines when cultivating cucumbers in a vinyl greenhouse, for example.

[Prior art]

Conventionally, when cultivating lily cucumbers, etc. in a plastic greenhouse, as the vines grow, the tips of the vines are sequentially moved horizontally in the direction of the arrows as shown in Figure 9, so-called vine-dropping work is performed, and each time the inside of the plastic greenhouse is cultivated. The wire 2, which is a linear body stretched over the wire, is fastened with plant growing scissors 4, and as shown in FIG. While holding 2,
It has been proposed that a holding space part 8 connected to the holding part 6 is capable of supporting the vine and the base of the leaf. Note that 5 is the ridge in which the Japanese cucumbers were planted.

[Problems with conventional technology]

However, with the conventional plant growing scissors 4, as the vines inserted and held in the holding space 8 enlarge, the wire 2 bites into them, causing problems such as breaking the vines and inhibiting their growth. There was a problem that if the holding space was made larger, vines and leaves in the early stages of growth would fall off.

The present invention was developed against the background of these circumstances, and the purpose of the present invention is to sufficiently retain the stems and leaves even in the early stages of growth, and to prevent the formation of linear objects such as wires even when the stems and leaves become enlarged. To provide a scissors tool for growing plants that does not bite.

[Means for solving problems of conventional technology]

The present invention has been made to achieve such an objective, and the gist of the present invention is as follows: A. A clamping device for clamping a linear body stretched at one end or a similar member. a pair of clamping body members each having a gripping portion formed at the other end for gripping with fingers, and a connecting protrusion for connecting to each other at the intermediate portion;
They are connected so that they can be opened and closed via both connecting protrusions, and are biased by a spring member in the direction that both clamping parts come into contact with each other. In the plant growing scissors tool, each gripping part has a U-shape or a V-shape on its tip side. A scissors for growing plants, which is formed with a recess in the shape of a rectangular shape or a rectangular shape, and is provided with individual protrusions that are formed in the vicinity of the holding space in a direction that crosses the holding body member so as to be able to come into contact with each other, and B. Item A above. In the plant cultivation scissors described above, instead of the clamping part having a U-shaped, V-shaped, or rectangular recess formed on the tip side, each clamping part has a clamping part that extends in a direction transverse to the tip of the clamping body member near the holding space. A plant-growing scissors device comprising individual protrusions formed so as to be able to abut each other; D. The scissors for growing plants according to item A or B, which has a gap large enough to hold the plant. The invention consists of the plant growing scissors described in Section C; Here, the member similar to the linear body includes, for example, a string-like body.

[Effect]

In the plant growing scissors configured as described above, the gripping part is provided with a single protrusion near the holding space that can touch each other in the direction across the gripping main body member, so that it is possible to grip the linear object. This makes it possible to easily change the relative angular position of the linear body with respect to the holding space.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

The scissors for growing plants of this invention are usually about the size of clothespins, and are shown in Figures 1-
In FIG. 7, it is shown enlarged. In FIGS. 1 to 3, reference numerals 12 and 14 are clamping main body members, and clamping parts 16 and 18 are provided at one end of each.
Gripping parts 20 and 22 are formed at the other end, and coupling protrusions 24 and 26 are provided at the intermediate part thereof. As shown in FIG. 3, the coupling protrusion 24 has a protrusion 28 with a semicircular tip and a semicircular recess 30, and the engagement protrusion 26 also has a similar protrusion 32. A recess 34 is formed, and the protrusion and recess fit into each other so that they can be coupled. As a result, the holding main body members 12 and 14 are connected so as to be openable and closable, and the holding parts 16 and 14 are coupled together by the spring member 36.
18 are biased in the direction of contacting each other.

As shown in FIGS. 2 and 4, the clamping parts 16 and 18 are made wider than the other parts of the clamping main body member, and have U-shaped recesses 38 and 40 formed on their tip sides, and are further abutted. On the surface side, there is a holding space 4 which will be described later.
Single protrusions 42, 4 that are capable of coming into contact with each other in a direction that crosses the holding main body members 12, 14 near 8.
4 is formed, and the intermediate portions of the protrusions 42 and 44 are lower than both ends to form a gap 46 as shown in FIG.
is made to occur. Note that the gap 46 is made smaller than the diameter of the wire 2, which is a linear body to be held during use, and is determined to be able to sufficiently hold the wire 2. Furthermore, protrusions 45 are formed at both ends of the contact surfaces of the holding parts 16 and 18 on the outside of the recesses 38 and 40, respectively.

A holding space 48 is provided between the holding parts 16, 18 and the connecting protrusions 24, 26, and can be opened by holding both the holding parts 20, 22 with fingers. It is said that The holding body member 14 has a holding space 4 as shown in FIG.
A plurality of serrations 50 are provided along the outer periphery of 8, and the inner protrusion is bulged out to be slightly higher than the outer protrusion. Similar protrusions are provided on the holding main body portion 12 as well. Note that a curved inner wall surface may be provided on the outer periphery of the holding space 48 without providing the protrusion.

Scissors for plant cultivation 5 configured as above
4 is used in the same manner as the conventional example shown in FIG. 9, but since the holding parts 16 and 18 are provided with recesses 38 and 40, and the protrusions 42 and 44 are in contact with the vicinity of the tops of the recesses 38 and 40. As shown in FIG. 7, as the cucumber vine 56 enlarges, the angular position of the holding space 48 with respect to the stretched and fixed wire 2 can easily change, so the vine 56 may bite into the wire 2 and break. It is possible to avoid problems such as growth or growth being inhibited.
Furthermore, a gap 46 is provided between the contact surfaces of the holding parts 16 and 18.
This has the advantage that the plant growing scissors 54 can be prevented from falling off laterally from the clamped wire 2, and the stepped portions on both sides of the gap 46 serve as guides when clamping the wire 2. There is also.
Furthermore, the U-shaped recesses 38 and 40 help guide the wire 2 between the clamping parts 16 and 18 when the wire 2 is clamped, thereby improving work efficiency. According to experiments conducted by the inventors of the present application, it was possible to increase the work efficiency by about four times compared to the conventional example. Normally, in the forced cultivation of Japanese cucumbers, about 5,000 plant growing scissors are used per 10 ares, and the attraction and holding work is carried out many times at intervals of about 1 week to 10 days, but this process accounts for a large portion of the total production cost. Since the cost of attraction and holding work is large, the plant growing scissors of this embodiment can greatly contribute to reducing production costs. Furthermore, since the clamping parts 16 and 18 are made wider than the other parts of the clamping body member, when the clamping body members 12 and 18 are used as shown in FIG.
4 can be made small, that is, the holding body members 12 and 14 can be held so that they are along the horizontally stretched wire 2, so that the lily vines that are attracted and held in the holding space 48 are straight upwards. It stretches quickly and grows well. In addition, the holding parts 16,1
The longitudinal protrusions 45 provided on the abutment surface of 8 are effective when used while holding a string-like body stretched in the vertical direction. Further, since a sawtooth-shaped protrusion 50 is provided on the outer periphery of the holding space 48, the vines of the Japanese cucumber are prevented from falling off, and the protrusion 50 is expanded from the outside to the inside. Because of this, the pinched lily vines have room to swing due to the wind, etc., and breakage is prevented.

The plant growing scissors 60 shown in FIG. 8 is provided with a clamping part consisting of a single horizontal protrusion 66 and 68 at the tip of the clamping main body members 62 and 64, respectively, and a holding space part 70 is provided in this. They are set up consecutively. A gap 72 similar to that shown in FIG. 5 is formed in the contact surfaces of the protrusions 66 and 68.

In the embodiments shown in FIGS. 1 to 7, it is also possible to provide V-shaped or rectangular recesses in place of the U-shaped recesses 38 and 40, and the width of the clamping parts 16 and 18 can be further increased. It is also possible to make it the same as other parts of the holding body member. Further, in each of the embodiments described above, other known coupling protrusions may be used instead of the coupling protrusions 24 and 26.

Although each of the above-mentioned embodiments describes the scissors for growing Japanese cucumbers, the present invention can also be applied to other plants other than Japanese cucumbers.

Although several embodiments of the present invention have been described above, the present invention is not limited to these embodiments in any way, and can of course be implemented in various forms without departing from the gist of the present invention. It is.

According to the plant growing scissors tool according to claim 1,
Each clamping part is provided with a single lateral protrusion so that the length of the linear object to be held can be reduced, so the relative angular position of the holding space to the stretched linear object can be easily adjusted. As the vines, etc. enlarge, the gap between them and the filamentous bodies becomes larger, and it is possible to avoid the filamentous bodies from biting into the vines. The gap with the linear body is small and can prevent vines etc. from falling off, and the U-shaped recess serves as a guide when clamping the stretched linear body, making it easy to use. It is possible to improve work efficiency at the time.

According to the plant growing scissors tool according to claim 2,
Since the length of the clamping portion of the linear body can be reduced by the clamping portion provided with a single protrusion, it is possible to prevent the linear body from being bitten by vines, etc., as described above.

According to the plant growing scissors tool according to claim 3,
Since a gap is provided between the contact surfaces of the clamping parts to hold the linear object, it is possible to prevent the plant cultivation scissors from coming off and falling off the linear object, and the both ends of the gap are used to hold the linear object. It can serve as a guide during work and improve work efficiency. According to the plant growing scissors according to claim 4, since the plurality of serrated protrusions are formed along the inner periphery of the holding space, it is possible to prevent the vines, etc. that are attracted and held from falling out. .
