Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixing clip device for greenhouse curtain wire, etc.

This type of fixed clip device was developed, for example, by
As described in Japanese Patent No. 57-129349, it is used for opening/closing devices such as greenhouse curtains.

First, we will explain the configuration of an automatic curtain opening/closing device for greenhouses, etc., which has been conventionally used, with reference to an embodiment shown in FIGS. 1 and 2. The shaft is integrally provided with opening/closing drums 2 at predetermined intervals in its longitudinal direction. A central drum 3 is rotatably provided opposite the opening/closing drum 2, and curtain drive wires 4a, 4b are endlessly wound between the drums 2, 3. Therefore, both wires 4a and 4b move toward each other as the drive shaft 1, opening/closing drum 2, and central drum 3 rotate. Here, if the guide wire 6a located at the tip of the upper curtain 5a is connected to one curtain drive wire 4a, and the guide wire 6b located at the tip of the lower curtain 5b is connected to the other curtain drive wire 4b, Theoretically, both curtains 5a and 5b can be opened or closed simultaneously by forward or reverse rotation of the drive shaft 1. However, generally the curtains 5a, 5
Since the curtains b cover the ceiling of a fairly large greenhouse, they not only have a considerable weight, but if there is wind blowing up or moisture from dew, the load will further increase. The load is applied to the guide wires 6a, 6b and the curtain drive wire 4a,
It will concentrate on the connection part with 4b.

In FIGS. 1 and 2, 7a and 7b are curtain drive wires 4a and 4b and curtain 5a, respectively.
The load of the curtains 5a, 5b is concentrated on the clips 7a, 7b, which are provided at the connecting portions of the curtains 5b with the guide wires 6a, 6b.

Therefore, if the clips 7a, 7b come off the curtain drive wires 6a, 6b, it becomes impossible to open or close the curtains 5a, 5b, but in this case, the curtain drive wires 6a, 6b and the clips may slip. If the curtains do not move as one, it is impossible to open and close the curtains smoothly.

On the other hand, in the curtain opening/closing device of the embodiment, a rotating drum 8 is provided opposite to the central drum 3 in symmetry with the opening/closing drum 2, and curtain drive wires 9a, 9b are connected between both drums 3, 8 in the same manner as described above. It is wrapped endlessly. Similarly to the above, the opening/closing end guide wire 11a of the upper curtain 10a is connected to the curtain drive wire 9a, and the lower curtain 1 is connected to the other curtain drive wire 9b.
The opening/closing end guide wire 11b of 0b is connected,
The curtains 10a and 10b are also opened or closed simultaneously by the forward or reverse rotation of the drive shaft 1, central drum 3, and rotating drum 8.

Clips 12a and 12b are provided at the connecting portions between the curtain drive wires 9a and 9b and the guide wires 11a and 11b at the ends of the curtain, respectively.

Therefore, if the clips 12a, 12b come off the curtain drive wires 9a, 9b, it will be impossible to open or close the curtains 10a, 10b.
In this case too, in particular, the curtain drive wires 9a, 9
If b and the clip do not move together, the curtain cannot be opened and closed smoothly.

In the conventional Japanese Utility Model Application Publication No. 57-129349, a wire is attached using a clip consisting of a pair of members, a male part having a fixed leg and a female part having a fitting hole into which the fixed leg fits. A fixing clip device for greenhouse curtain wires and the like is described that is designed to clamp and fix greenhouse curtain wires, but the fixing legs are provided in a staggered manner away from the area where the wires to be clamped are stretched, so the wires in the tension direction are The clip is inserted completely independently of the fixing leg, making it impossible to securely fix the wire at all.

In view of this, the present invention provides for the clips 7a, 7b, 12a, and 12b, which support the guide wire at the opening/closing end of the curtain and integrally interlock with the curtain driving wire that moves in the opening/closing direction of the curtain, to provide a strong force from the wire. As a fixing clip device for greenhouse curtain wires, etc. that are subjected to tensile loads, the curtain can be opened and closed using a pair of clips consisting of a male part with fixing legs and a female part with a fitting hole into which the fixing legs fit. In a fixing clip device for greenhouse curtain wire, etc., which supports the end of the curtain drive wire and clamps and fixes the curtain drive wire, the male part is fitted into the tension area of the curtain drive wire along the tension direction of the curtain drive wire. At least 3 staggered
At least one fixed leg is provided, and the interval between adjacent fixed legs in a staggered manner is set to a dimension equal to or less than the diameter of the wire, while the wire is inserted into the female part along the tension direction of the curtain drive wire. It is an object of the present invention to provide a fixing clip device for a greenhouse curtain wire or the like, characterized in that a slot is provided and a fitting hole into which the fixing leg is fitted is provided.

The fixing clip device according to the present invention will be explained in detail with reference to the embodiment shown below. The clip in the device of the present invention consists of a male part 21 and a female part 31, as shown in FIGS. 3 to 9. The male part 21 has four fixed legs 22a, 22b, 22.
The female part 31 is provided with fitting holes 32a, 32b, 32c, and 32d facing each other, into which the fixed legs 22a to 22d can fit, respectively. Further, the guide wires 6a, 6b, 11a, 11 of the curtain are provided in the male part 21.
A slot 23 is provided into which the connector b can fit. Furthermore, a slot 23 is provided in the female mold part 31 passing through between the fitting holes 32 a to 32 d of the female mold part 31 in a direction perpendicular to the slot 23 , and a curtain drive device inserted through the slot 33 is provided. The structure is such that the wires 4a, 4b, 9a, 9b can be fixed respectively.

That is, the fixed legs 22a, 22b,
Distance d between which the wires 4a of 22c and 22d should be inserted
In the case of the device of the present invention, as shown in FIG. 8, the diameter of the wire 4a is set to be smaller than the diameter of the wire 4a, and the wire 4a passing between the wires is bent and fixed in a meandering state by the fixed legs. Further, the fitting holes 32a, 32b, 32c, and 32d of the male part 31 are also drilled so as to be recessed into the slot 33 through which the wire is inserted, and the wire is further compressed by the side wall 33a of the slot 33. The condition will be fixed.

Therefore, according to the device of the present invention, the curtain drive wires 4a, 4b and 9a, 9b are bent and fixed in a meandering manner between the fixed legs 22a to 22d of the clip, which are narrower in distance than the wires, while Fitting hole 3 drilled by inserting into slot 33 of female part 31
Since it is fixed to the side wall 33a facing the wires 2a to 32d in a compressed state below the diameter of the wire, it can counter the tensile force of the wire with a large clamping force and frictional resistance, and is integrated with the curtain drive wire. This results in a strong connection as a solid clip.

Although the configuration is not unique to the fixing clip device of the present invention, in the embodiment, a plurality of curtain presser wires 13 are stretched at predetermined intervals on the top surface of the curtain along the opening/closing direction of the curtain, and A ring frame integrally provided with each clip is movably inserted through the wire 13. That is, a ring frame portion 40 is integrally placed on one male portion 21 of the clip.
The ring frame portion 40 is made up of upright frames 41a, 42a parallel to the curtain driving wire and curtain holding wire, and ring closing frames 41b, 42b overlapping each other with a gap 43 in between. The gap 43 is created by mutually elastically deforming the ring closing frames 41b and 42b.
3 may be inserted therethrough, and the male part 21 and the ring frame part 40 may be integrally formed by plastic molding.

As described above, according to the fixing clip device for greenhouse curtain wire or the like according to the present invention, a pair of members including a male part having fixing legs and a female part having a fitting hole into which the fixing legs fit. In a fixing clip device for a greenhouse curtain wire or the like, which supports the curtain opening/closing end with a clip made of At least three or more fixed legs are provided in a staggered pattern embedded in the tensioning area, and the interval between adjacent fixed legs in a staggered pattern is set to a dimension equal to or less than the diameter of the wire, while the tension of the curtain driving wire is set in the female part. The structure is characterized in that a groove is provided along the direction through which the wire is inserted, and a fitting hole is provided in which the fixed leg is inserted into the groove, so that a strong tensile force of the curtain driving wire etc. is provided. Along the tension direction, the wire is bent and meandered between narrow staggered fixed legs having a diameter smaller than the diameter of the wire, and the wire is bent and meandered in the slot between the fixed legs and the opposite narrow side wall. It has the effect of firmly connecting the curtain drive wire and the clip with a large clamping force and frictional resistance against the strong tensile force applied to the curtain drive wire. As a fixed clip device for connecting the opening/closing end and the curtain drive wire, its benefits are considerable.
