Open and close the curtain member.

JP-A-2006-325401

The first and second curtain members of Patent Literature 1 are respectively supported on first and second shelf lines spanning the sides of the greenhouse, and move on each shelf line together with the leading pipe when opening and closing. On the other hand, in order to prevent each curtain member from fluttering due to the wind, a stop line is provided above each curtain member so as to span between the sides of the greenhouse corresponding to each shelf line.

In order to arrange each curtain member between each shelf line, the flap line is provided several centimeters above each shelf line. Specifically, as shown in FIG. 2 of Patent Document 1, one shelf line 50 is stretched between the vicinity of the upper portion of steel materials 111 and 121 provided on each side of the greenhouse, and each steel material 111 and 121 One swing stop line 51 is stretched between the vicinity of the upper end of the flange portion of the mounting cover which covers the outside of the steel members 111 and 121 and has a flange portion projecting several cm above and below the steel members 111 and 121 . The other shelf line 60 is stretched between the vicinity of the lower end of the flange portion of the mounting cover, and the other tilt stop line 61 is stretched between the vicinity of the lower portions of the respective steel members 111 and 121 located several centimeters above. there is

That is, the shelf line that supports the lower side of the curtain member to prevent the curtain member from sagging downward, and the flap that is arranged on the upper side of the curtain member to prevent the curtain member from flapping due to being shaken. The tethers are stretched across both sides of the greenhouse in opposite directions in the opening and closing direction of the curtain members, but must be connected to members of different heights on each side. Therefore, in Patent Literature 1, members for connecting the shelf line and the stop line are provided at the upper and lower ends of the steel members 111 and 121 and the upper and lower ends of the flange portion of the mounting cover, respectively.

Not limited to Patent Document 1, when arranging such a shelf line and a stop line, the opening and closing direction of the curtain member is usually the opposite direction of both side surfaces of the greenhouse. Connecting linear members are provided at different heights so as to extend in a substantially horizontal direction substantially orthogonal to the opening and closing direction of the curtain member, and each end of the shelf line and the flap line is connected to each of them. That is, it is necessary to provide two connecting linear members for the shelf line and the gate stop line on each side of the greenhouse, which is a factor in complicating the installation work of the greenhouse and increasing the installation cost.

In order to simplify the installation work, etc., there is a case where one wire is used as a connecting linear member provided on the side surface, and both the shelf wire and the flap wire are connected to the one wire. However, in that case, the gap between the shelf line and the stop line becomes narrower, and the smoothness of the movement of the curtain member is impaired. When trying to do so, the curtain member may be sandwiched between the two and damaged.

The present invention has been made in view of the above. While the installation work can be simplified and the cost can be reduced, the gate stop line can be arranged above the shelf line, and the curtain member can be caught between the two, causing damage. It is an object of the present invention to provide a flapping stop line connector capable of preventing this.

In order to solve the above-described problems, the swing stop line connector of the present invention is
