DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoisting member holding device and, more particularly, to a technique for holding a hoisting member for winding up a sheet member covering a framework of a greenhouse.

[0002]

2. Description of the Related Art In a greenhouse such as a greenhouse, almost the entire frame is covered with a sheet member. Generally, the skeleton is formed of a steel frame or the like. In addition, a film (for example, a vinyl sheet) or a cloth material is used for the sheet member, and a heat retaining effect can be obtained by the sheet member. However, due to the heat retention effect, the temperature in the greenhouse may be higher than necessary depending on environmental conditions such as the four seasons, weather, and sunshine hours. Also, depending on the crops to be cultivated, the air in the greenhouse must be replaced.

[0003] In view of the above, it is easy to temporarily remove a sheet member covering a part (for example, a wall or a roof) or the whole of the greenhouse in order to control the temperature in the greenhouse or to perform ventilation. is there. Therefore, in a conventional greenhouse, a winding device for winding a sheet member is attached, and a part or all of the greenhouse is opened as necessary.

Is a greenhouse framework 10 assembled by pipes and the like.
2 attached. At the end of the sheet member that covers the frame 102, a winding member 16 is provided by a clip or the like. Then, after the winding member 16 is turned to wind the sheet member of the portion to be opened around the winding member 16, it is fitted into the inverted U-shaped holding device 100 from the direction of arrow D <b> 20. By this fitting, the holding device 100
Holds the winding member 16. This holding device 100
As shown in FIG. 11, in order to hold almost all of the winding member 16, it is necessary to attach the winding member 16 linearly over substantially the entire length of the framework 102 in the longitudinal direction of the greenhouse 104.

[0005]

However, since a greenhouse is usually built with the lower end of the framework buried in the ground, it is necessary to construct a new foundation for the framework in order to align the framework in a straight line. There is a need to do. Therefore, attaching the above-mentioned holding device to the framework of the greenhouse requires considerable labor and time. In particular, it is difficult to align already completed greenhouse frameworks in a straight line. Further, since the winding member is merely held by being fitted into the holding device, the winding member may come off the holding device when the wind blows strongly. The present invention has been made in view of such a point, and an object thereof is to realize a hoisting member holding device that is easily attached to a framework of a greenhouse and that reliably holds a hoisting member even when a strong wind blows. It is.

The support rod 28 can be positioned at a desired position by passing the support rod 28 through the through hole 24b, and can be fixed at that position with a bolt or the like. Therefore, the distance L between the holding member 24 and the pipe 26 shown in FIG. 5 can be adjusted. On the other hand, the plate-like portion 24g is a plate-like member formed in a substantially E-shape, and is opened at a central portion on the opposite side to the cylindrical portion 24a. The plate-shaped portion 24g is provided with a concave portion with the convex portion 24d interposed therebetween. One side (the upper side in FIG. 3A) is a pressed state holding portion 24f, and the other side (FIG. 3A In (), the lower side) is the non-pressed state holding portion 24d.

In the holding device 10 having the above-described configuration, the following operation is performed to bring the winding member 16 into the pressed state. First, in FIG. 4, the winding member 16 is positioned at a position to be held. This positioning is possible by a device for rotating the winding member 16. Then, in FIG. 5, the switching member 22 held by the non-pressed state holding portion 24d is operated to switch over to the pressed state holding portion 24f over the convex portion 24e. By this switching, the pressing member 20 fixed to the switching member 22 rotates in the direction of arrow D4 to press the winding member 16 toward the skeleton side. 6 and 7 show the pressed state. In the pressed state, the pressing member 20 and the pipe 1
Since the pressing member 8 presses the hoisting member 16, the hoisting member 16 is firmly held in the greenhouse. for that reason,
The winding member 16 is securely held even when the wind blows strongly.

On the other hand, to release the pressed state of the winding member 16, the following operation is performed. First, in FIG. 6, the switching member 2 held by the pressed state holding portion 24f is set.
2 is operated again to switch over to the non-pressed state holding portion 24d after getting over the convex portion 24e. By this switching, as shown in FIG. 7, the pressing member 20 rotates in the direction of arrow D6 to open the winding member 16. Thus, the winding member 1
6 is released, and the state returns to the state shown in FIG. This
In the state of, the sheet member is wound by the winding member 16.
Can be lifted. In this manner, simply by switching the switching member 22 between the non-pressed state holding portion 24d and the pressed state holding portion 24f, the holding and release of the winding member 16 can be easily performed. Therefore, the operation is simple and can be performed quickly.

Therefore, according to the holding device 10,
Since the holding member 24 (holding unit) holds the pressed state switched by the switching member 22 (switching unit), the winding member 16 is firmly held in the greenhouse by the switching member 22. Therefore, even when the wind blows strongly,
6 can be held. When attaching the holding device 10 to the pipes 12, 26 or the like (framework of a greenhouse),
There is no need to arrange the pipes 12, 26 and the like in a straight line.
Therefore, attachment to the pipes 12, 26 and the like can be easily performed. Further, the distance L between the holding member 24 (the part holding the pressed state) and the pipe 26 (framework) can be adjusted depending on which position of the support rod 28 the holding member 24 is fixed to (see the figure). 5) . Therefore, it can be easily attached to a framework of a greenhouse having different inclination angles, curvatures, and the like in the roof portion. Further, since the support rod 28 is rotatable with respect to the pipe 26, it is possible to easily switch between the pressed state and the non-pressed state by the switching member 22. The holding device 10 is desirably installed in the greenhouse at intervals of several meters in relation to the bending of the pipe 18 supported by the pressing member 20.

[Second Embodiment] Next, a second embodiment will be described with reference to FIG. here,
FIG. 8 shows another hoisting member holding device, and FIG.
FIG. 8B is a perspective view looking down from above, and FIG. 8B is a side view. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In FIG. 8, the holding device 50 includes a pressing member 20, a switching member 52, a holding rod 54, and support plates 56 and 58. The switching member 52 is a member having the same function as the switching member 22, is fixed to the pressing member 20, and has the pipe 14 as an axis and arrows D8 and D10.
Swingable in any direction. The support plates 56, 58

2 is a greenhouse as shown in FIG.
It is provided inside the IP 30).

The holding rod 54 is a specific example of a holding means, and switches between a pressed state and a non-pressed state depending on the position of the switching member 52. That is, when the holding rod 54 is removed from the support plates 56 and 58 and the switching member 52 is turned in the direction of the arrow D10, the pressing member 20 rotates in the direction of the arrow D4. Thereafter, when the holding rod 54 is attached, the pressing state as shown in FIG. become. On the other hand, when the holding rod 54 is removed from the support plates 56 and 58 and the switching member 52 is turned in the direction of arrow D8, the pressing member 20 rotates in the direction of arrow D6.
A non-pressing state (for example, the same state as in FIG. 4) is set. Since the holding rod 54 firmly holds the switching member 52, it is possible to reliably hold the pressed state or the non-pressed state.

Therefore, according to the holding device 50,
The same effect as in the first embodiment can be obtained. The support plate fixed to the two skeleton pipes 60 and 62 may be a single plate, and the holding bar 54 may be detachably attached to the support plate, or the holding bar 54 may be fixed to the support plate. . In this case, it is desirable that the holding rod 54 be formed in a shape such as a T-shape or an L-shape that makes it difficult for the switching member 52 to easily come off.
