Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a skylight structure for a greenhouse, and more particularly, to a skylight structure for a greenhouse comprising a plurality of roof frames arranged in rows at predetermined intervals.

(Prior art) Conventionally, this type of skylight structure has been used, for example, in the 1980s
- As shown in Publication No. 46869, a pair of vertical members and a plurality of horizontal members are installed between these vertical members at equal intervals to the arrangement interval of the split roof frames, which are arranged in a row in an unfinished state with their tops separated. A lower frame of the skylight is formed, and a lever is swingably supported on the lower frame, and an upper frame of the skylight is formed by framing a pair of vertical members and a plurality of horizontal members, and this upper frame is The upper frame is supported by the lever so that the upper frame can be opened and closed with respect to the lower frame by swinging of the lever, and means for connecting to the top of the split roof frame is provided at both ends of the cross member of the lower frame. It is known that the lower frame is interposed between the tops of the split roof ribs and is connected to and attached to the roof ribs.

(Problems to be Solved by the Invention) However, in the case of such a conventional skylight structure, when the skylight structure is incorporated into a split roof frame, the lower frame is lifted to the top of the split roof frame, and With the lower frame interposed between the tops of the roof frame, both ends of the cross members of the lower frame must be inserted into the top of each roof frame and fixed between the tops of the roof frames. Assembling the lower frame to the split roof frame is very troublesome and time-consuming, and furthermore, the upper frame is connected to the lower frame via a lever, and the structure is such that the lever can be opened and closed by swinging. Therefore, after the lower frame is attached to the split roof frame, it is necessary to assemble the lever to each of the lower frame and the upper frame so as to swing the lever, which makes the assembly work very complicated. However, there was a problem with poor assembly on-site.

The purpose of the present invention is to improve the ease of assembling the lower frame of the skylight to the roof frame and the upper frame of the skylight to the lower frame, so that on-site assembly can be performed easily and quickly. The aim is to provide a skylight structure that can be immediately applied to existing greenhouses.

(Means for Solving the Problems) The present invention is a greenhouse skylight structure consisting of a plurality of roof frames arranged in a row, and includes a pair of vertical members and a plurality of horizontal members installed between these vertical members. An upper frame is formed by framing a lower frame, a pair of vertical members, and a plurality of horizontal members installed between these vertical members, and a drive member having a rotating member, and a drive member having a rotating member, and forming a drive mechanism consisting of a vertically moving member that is removably fitted into the rotary member and moves up and down with the rotation of the rotating member;
The driving member is attached to the horizontal member of the lower frame, the lower frame is placed and fixed on the upper part of the roof frame, the vertically movable member is attached to the horizontal member of the upper frame, and the horizontal member is attached to the vertical member. The upper frame is attached to the lower frame so that its position can be changed, and the upper frame is movable up and down with respect to the lower frame by inserting the vertically movable member into the drive member, and the upper frame is detachably connected to the lower frame.

(Function) Therefore, the upper frame and the lower frame constituting the skylight are formed by framing a pair of vertical members and a plurality of horizontal members separately from the framework of the completed greenhouse, and the horizontal members of the lower frame are Since the drive member of the drive mechanism is attached to the cross member of the upper frame, and the vertically moving member of the drive mechanism is attached to the cross member of the upper frame, the lower frame and the upper frame can be assembled in advance on the ground. The lower frame can be easily placed and fixed on the upper part of the roof frame without having to frame the lower frame at the upper part.
In addition, since the drive member and the vertical movement member of the drive mechanism, which can be inserted and removed in the vertical direction, are attached to the lower frame of the upper frame configured as described above, the lower frame placed and fixed on the roof frame can be fixed to the roof frame. The upper frame can be easily assembled to the lower frame so as to be movable up and down relative to the lower frame simply by fitting the vertically movable member of the upper frame into the drive member so as to be movable up and down. Therefore, the skylight consisting of the lower frame, the upper frame, and the drive mechanism can be attached to the upper part of the roof frame of the greenhouse with a simple operation, and the assembly on site is extremely simple, easy, and quick. In addition to this, it can also be applied immediately to existing greenhouses.

Moreover, since the horizontal member of the upper frame is attached so that its position can be changed with respect to its vertical member, the position of the horizontal member to which the vertically moving member of the upper frame is attached to the drive member can be adjusted, that is, the lower part of the vertical member of the upper frame can be adjusted. The longitudinal position of the frame relative to the longitudinal members can be adjusted accurately, and the ease of assembling the upper frame to the lower frame can be further improved.

The longitudinal members 81 are superimposed on substantially the same plane.
The film 4 can be pressed down to improve airtightness when the window is closed, and the upper frame 8 can be opened even when it rains, compared to a so-called flip-up type window frame that opens and closes using a conventional hinge. Rain is difficult to penetrate.Furthermore, since the presser band for fixing the film 4 to the frame of the greenhouse can be passed under the upper frame 8, there is no need to divide the band and a decrease in strength can be prevented.

Further, the drive shaft 13 and the cylindrical shaft 7 of the pinion 71
1a can be fixed at any rotational position with the set bolt 71b, for example, even if the heights of the racks 75 of the plurality of drive members are different from each other when the pinion 71 is engaged with the rack 75, the upper frame 8 can be fixed at any rotational position. By positioning the drive shaft 13 in the closed position, the drive shaft 13 is aligned with the cylindrical shaft 7 with the misalignment corrected.
1a, and its assemblability can be improved.
