Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a daylighting frame suitable as a roof covering for solar energy collecting roofs.

Prior Art The present applicant first assembled a pair of left and right vertical bars, an upper horizontal bar, and a lower horizontal bar into a rectangular shape, and fitted a glass inside thereof to produce a daylighting glass frame as disclosed in Japanese Patent Application Laid-Open No. 1-275832. proposed as. However, since each glass is laid side by side vertically and horizontally so that each glass is included in the same plane, the lighting glass frames that are adjacent to each other in the direction of the eaves are not overlapped, and they are lowered to close the gap between the lighting glass frames. It was necessary to install a covering lid on the horizontal rail. As a result, drainage on the top surface of the roof is poor, dust tends to accumulate on the top surface of the glass, and snow tends to accumulate especially in areas with heavy snowfall.The length of the glass in the direction of the eave ridge is short, so the light gathering area is small and the energy The drawback was that collection efficiency was poor.

Another possibility is to lengthen the glass in the daylighting glass frame and lay the front end of the glass on the line side overlapping the top of the rear end of the glass located on the eave side. Since the slope of the base is different from the slope of the glass, if the lower edge of the vertical frame and its glass support groove are parallel, a gap will be created between the lower edge of the vertical frame and the roof base, resulting in poor rain protection. If the lower edge of the vertical bar and the glass support groove are inclined in order to eliminate this problem, the vertical bar cannot be extruded and molded. Furthermore, since the angle of inclination of the glass varies depending on the length of the glass in the eave direction, vertical bars must be manufactured in different shapes depending on the dimensions of the daylighting glass frame.

Problems to be Solved by the Invention The purpose of the present invention is to provide a lighting system that can be used for roofs of various sizes, has good rain control, has no risk of snow or dust accumulation, has a large light collection area, and is easy to manufacture. It's about providing a framework.

Means for Solving the Problems In order to solve the above problems, the roof lighting frame of the present invention has the following features:
Transparent plate support bars are installed along the inner surfaces of a pair of left and right vertical bars, with their front ends inclined at a greater distance from the lower edge of the vertical bars than their rear ends, and between the front ends of the light transmitting plate support bars. At the same time, a lower horizontal bar is installed between the rear ends of the transparent plate support bars, and the interior of the space formed by the transparent plate support bars, the upper horizontal bars, and the lower horizontal bars. It has a structure characterized in that a light-transmitting plate is stretched over the lower horizontal crosspiece, and a fitting recess that fits into the upper horizontal crosspiece is formed along the longitudinal direction at the lower front end of the lower horizontal crosspiece.

By fitting the insertion recess of the lower horizontal beam and the upper horizontal beam and overlapping the transparent plate, the gap between adjacent lighting frames in the direction of the eaves is closed, the area of the transparent plate is increased, and the transparent plate is overlapped. The light-transmitting plate support bar is attached at an angle to a separate vertical bar according to the inclination of the light plate.

As shown in FIG. 18 and FIG. A screw 44 is inserted into the groove 36 to assemble a rectangular frame.

In addition, the transparent plate insertion frame 25 of the transparent plate support bar 11, the upper horizontal bar 1
2 translucent support groove 35 and the translucent plate mounting piece 38 of the lower horizontal crosspiece 13
The four circumferences of the light-transmitting plate 14 are supported by the upper surface via the backing, and no protrusion is formed on the upper surface of the light-transmitting plate 14 at the edge of the eaves, which prevents accumulation of dust, rainwater, and snow. The structure is as follows.

At this time, since the mounting holes 24 near the eaves of the vertical beam 10 are bored higher than the mounting holes 24 near the ridge, the transparent plate support beam 11 is vertically mounted as shown in FIGS. 16 and 17. It is attached to the crosspiece 10 so as to be inclined upward in the direction of the eaves, and the lower horizontal crosspiece 3 is installed above the upper horizontal crosspiece 12.

Next, a method for installing the lighting frame 1 will be explained.

First, connect the connecting member 2.2' on the roof base along the direction of the eaves.
As shown in Figure 4, a waterproof plate 46 is placed on the roof surface.
and the standing waterproof walls 47 formed on both side edges thereof are housed in the lower width adjustment space 6 of the connecting member 2.2'. Next, as shown in FIG. 20, an eave support member 48 is arranged at the edge of the eave of the roof base, a needle member 5 is attached to the upper surface of the eave support member 48, and the end of the needle member 5 is connected to the lower horizontal beam. The lighting frame 1 closest to the eaves is laid so as to fit into the fitting recess 45 of No. 13,
The lower horizontal wing piece 16 of the vertical beam 10 is brought into contact with the upper end of the fitting groove 7 of the connecting member 2゜2', and the lower end of the vertical support leg 15 is brought into contact with the connecting member 2.
, 2' into the fitting groove 7 with a gap between the bottom surface of the groove 7 and the fixing tool 49 attached to the fitting groove 7.
Hold down the curved waterproof gutter 41 of No. 3, and fix the fixture engaging piece 37 of the upper horizontal member 12 with the same fixture 49, and fix the waterproof wall 2 of the vertical beam 10.
0 is inserted into the upper width adjustment space 8 of the connecting members 2, 2', and a gap is formed between the upper surface of the upper width adjustment space 8 and the upper end of the waterproof wall 20 to block capillary action.

Next, as shown in FIG. 21, another daylighting frame 1 is laid down for exploration, and the horizontal piece 31 of the upper horizontal piece 12 of the daylighting frame 1 adjacent to the eave side is inserted into the fitting recess 45 of the lower horizontal piece 13. The fixing member retaining piece 3 of the upper horizontal side 12 of the lighting frame 1 on the line side is fitted with the horizontal upper surface 33.
7 to lock the fixture 49.

Similarly, the daylighting frame 1 is successively raised in the direction of the ridge.

Further, above the light-transmitting plate 14 of the lighting frame 1 on the eave side, the light-transmitting plate 14 of the daylighting frame 1 on the line side is overlapped via the upper horizontal crosspiece 12 and the lower horizontal crosspiece 13. will be inclined at a smaller angle than the slope of the roof base.

That is, if the upper end of the upper horizontal member 12 of the lighting frame 1 and the fitting recess 45 of the lower horizontal member 13 are at the same height with respect to the lower edge of the vertical member 10, the lower edge of the vertical member 10 is parallel to the roof base. The vertical bar 10 has an upper horizontal bar 12 and a lower horizontal bar 13.
The mounting holes 24 near the eaves are drilled high, and the mounting holes 24 near the ridge are drilled low so that the mounting holes 24 have the above-mentioned positional relationship.

As a result, as shown in FIGS. 22 and 23, the slope of the translucent plate 14 with respect to the vertical beam 10 becomes steeper as the length of the lighting frame 1 in the eaves direction becomes shorter; Although the inclination becomes gentler, the relative inclination can be easily changed by separating the vertical bar 10 and the light-transmitting plate support bar 11.

Effects of the Invention As described above, the roof lighting frame of the present invention has a fitting recess at the front end of the lower part of the lower horizontal frame that fits into the adjacent upper horizontal frame when the roof is installed. There is no need to provide a covering lid part on the upper part of the lower horizontal beam, and therefore rainwater and snow smoothly flow down without accumulating on the upper surface of the lighting frame, and dust does not accumulate on the upper surface of the light-transmitting plate.

Furthermore, since the connection ends of the lighting frames adjacent in the direction of the eave ridge are overlapped, the light-transmitting plate can be made longer, the lighting area relative to the roof area becomes larger, and the light collection efficiency can be increased.

Furthermore, during roofing, the edges of the lighting frame overlap, so the roof base and the transparent board are relatively inclined, but by attaching the transparent board support bar at an angle to the vertical bar, The vertical beams can be installed parallel to the roof base, and since the vertical beams with different inclinations and the transparent plate support beam are separate pieces, these two components can be easily manufactured by extrusion molding, and the eaves of the lighting frame can be easily manufactured. Even if the angle of inclination of the light-transmitting plate support bar relative to the vertical bar changes as the length in the ridge direction changes, the change in the inclination angle can be easily accommodated using the same member.
