Embodiment 1 An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 to 5, reference numeral 1 denotes an agricultural and horticultural clip according to the present invention, which is made of a hard plastic material. That is, it is composed of an upper sandwiching member 2 and a lower sandwiching member 3, and each of the gripping members has a front side as a sandwiching portion 4 and 7, a rear side as a sandwiching portion 5 and 8, and a shaft support portion inside the sandwiching portion and the sandwiching portion. 6 and 9 are formed, the shaft supporting portions 6 and 9 are rotatably coupled by a shaft rod 10, and the holding surfaces 12 and 13 of both holding portions are pressed against each other by a coil spring 11 provided inside the shaft supporting portion. It is biased in the direction. In the present embodiment, the lower side is the side in contact with the ground when the clip is in use, and the opposite side is the upper side.

Thus, the upper sandwiching member 2 has two projections 14 formed on the sandwiching surface 12 of the sandwiching portion 4, and the gripping portion 5 is provided with a stringing side groove 15 on both sides of the gripping portion 5 near the shaft supporting portion 6. And the rear end portion is bent inward so that the fastening string is not easily separated.

Further, the lower sandwiching member 3 is provided with two receiving holes 16 on the sandwiching surface 13 of the sandwiching portion 7 that can be loosely fitted to the protrusions 14 of the upper sandwiching member 2, and the knob 8 is rearward. It is extended further to the side and a required number of pin holes 18 are provided in the extended portion 17.

[0011]

[Embodiment 2] In this embodiment, as shown in FIGS. 6 to 8, a string hooking piece 20 is provided on the outside of the holding portion of the upper holding member 2 so as to project. The cord hooking piece 20 is formed so as to be curved backward so that the cord for hanging the vinyl house 2 can be easily hooked. Further, the spring 11 is formed in a ring shape having an end, and is inserted into a through hole 21 provided near the shaft supporting portion of the upper and lower grip portions, and the respective end portions thereof are locked to the outer side surface portions of the holding portions 4 and 7, respectively. Two of these springs are juxtaposed. Also, the protrusion 14
Each of the receiving holes 16 is formed in the sandwiching surfaces 12 and 13 in an elongated shape. The other structure is substantially the same as that of the first embodiment.

[0012]

Third Embodiment In this embodiment, as shown in FIGS. 9 and 10, along the inner end of the holding surface 13 of the lower holding member 3, the holding surface of the lower holding member 2 is attached. A ridge 30 is provided which meshes with the inner edge of the twelve. In this example, the skirt of the vinyl sheet S is sandwiched between the sandwiching surfaces 12 and 13 in a bent state, and is sandwiched between the projecting edge 30 and the inner edge of the sandwiching surface of the lower sandwiching member. . Therefore, the hem of the seat can be more strongly clamped to the clip.

Next, the procedure for fixing the hem of the vinyl sheet S covered by the vinyl house with the clip according to this embodiment will be described. When both grip portions 5 and 8 are pressed against the elastic force of the spring 11, the shaft support portions 6 and 9 rotate and the holding portions 4 and 7 open, so that the sheet S is held between the opened holding surfaces 12 and 13. When the end portions of the gripping members 5 and 8 are pushed in so as to be rolled up and the gripping portions 5 and 8 are released, the sandwiching members 2 and 3 are moved to the spring 11
Is restored by the elasticity of the sheet and the sheet edges 12 and 13 sandwich the sheet edge. At that time, the protrusion 16 formed on the sandwiching surface 12 of the upper sandwiching member 2 is fitted into the receiving hole 14 formed on the sandwiching surface 13 of the lower sandwiching member 3, whereby the sandwiched portion of the sheet S is Since the sheet is pushed into the receiving hole 14 and clamped in a bent state, the edge of the sheet is securely clamped by the clip. Then, by placing the lower sandwiching member 3 of the clip 1 on the ground E on both the left and right sides of the vinyl house and driving the ground through the pin P through the pin holes 18, the seat hem can be fixed to the ground.

As shown in FIG. 5, the hem of the seat S is fixed to the ground along both sides in the longitudinal direction of the vinyl house by the clips 1 arranged on both sides of the house with a predetermined interval. Then, the clip 1 for fixing the sheet S
Are arranged in a staggered manner between the support frames arranged in parallel at predetermined intervals. Furthermore, when the fastening cord C is hung on the vinyl house, it is laid across the vinyl house on which the sheet S is covered so as to straddle the side groove 15 of the clip 1 or the string hook 20.
Hook onto and fasten. It is also practiced to cover the upper surface of the vinyl house with a net instead of hanging the fastening string, but in that case, the lower end of the net is put on the string hook side groove 15 or the string hook piece 20 of the upper knob 2. Just hook it.

[0015]

By using the agricultural and horticultural clip having the above-described structure, the seat hem of the vinyl greenhouse can be reliably fixed to the ground at required intervals, so that the ground can be dried, and strong winds and gusts can be prevented. Even if the seat hem is not rolled up, the vinyl house can be protected safely. Further, unlike the conventional case, it is not necessary to dig a long groove for burying the seat hem along both sides of the house, or to bury the seat hem in the long groove, which is very useful for agricultural work.

Further, as in the second embodiment, by providing the string hooking piece on the outer side of the holding portion of the upper picking portion, the work of bridging the fastening string can be performed more easily. Furthermore, Example 3
As described above, by providing the projecting edge that meshes with the inner edge of the other sandwiching surface along the inner edge of the one sandwiching surface, the skirt portion of the seat can be more reliably sandwiched.
