Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lighting device that is attached to windows, walls, fences, etc. of buildings.

[Prior Art] Blinds, curtains, curtains, blocks, etc. are used to block light or hide people.

[Problems to be Solved by the Invention] The aforementioned blinds, curtains, and blinds have the disadvantage that they sway when exposed to the wind, allowing the sun to hit them, and they no longer function as a blindfold. In addition, when blindfolded with blocks or the like, there was a drawback that the lighting was insufficient.

The present invention aims to provide a lighting device for windows, walls, fences, etc. that is strong against wind and can sufficiently serve as a light shield and a blindfold.

[Means for solving problems] This will be explained with reference to the drawings.

In the lighting device such as a window according to the present invention, both sides of a square surrounding frame 1 are formed into blind pillars 2, and both sides of oblong plates 3 arranged vertically in the space inside the surrounding frame are formed into double blind pillars 2.
It is supported by a horizontal support shaft 5 passing through each inner wall 4 and an intermediate wall disposed inside at least one of the bag pillars 2, and an arm member 6 is attached to the end of each horizontal support shaft 5 located inside the bag pillar 2. A connecting member 7 that is fitted and fixed and connects the tip of the arm member 6 is arranged in the vertical direction, and is attached to the tip of the arm member 6 with a rivet or the like 8, and is attached to the horizontal support shaft 5.
A worm wheel 9 is connected to rotate in conjunction with one of the worm wheels 9, and a rotation handle 12 is provided on the indoor side protrusion of a central shaft 11 of a non-reversible worm gear 10 that meshes with the worm wheel 9.

[Example] This will be explained with reference to the drawings.

Two intermediate walls 13,1 on both sides of the square surrounding frame 1
A bag post 2 having a diameter of 4 is formed. Both sides of the horizontally long plates 3 arranged vertically in the space within the surrounding frame are supported by horizontal support shafts 5 passing through the inner wall 4 of the bag post 2 and the first intermediate wall 13. An arm member 6 is fitted and fixed to each horizontal support shaft 5 located within the inner wall 4 and the first intermediate wall 13, respectively. A connecting member 7 made of a steel belt or the like that connects the tips of the arm members 6 is arranged in the vertical direction and is attached to the tips of the arm members 6 with rivets or the like 8. The horizontal support shaft 5
A worm wheel shaft 15 is connected to one of the first intermediate walls 12 and 12.
A rotary handle 12 is provided on an indoor side protrusion of a central shaft 11 of a non-reversible worm gear 10 which is rotatably supported by the worm wheel 9 and the second intermediate wall 14 .

Further, if the contact piece 17 is configured to fix the connecting member 7 when the camera 16 is operated, the maintenance of the stopped state can be reinforced.

Furthermore, if the necessary parts can be disassembled and assembled, the oblong board 3 can be rearranged with one of a different color as needed to change the mood.

[Operation] When the rotation handle 12 is turned, the worm gear 1
0, worm wheel 9, connecting member 7, arm member 6
are interlocked to rotate the horizontal support shaft 5 to maintain the horizontally long plate 3 at an arbitrary opening position.

[Effect of the invention] Even if the wind hits the horizontally long plate 3 and the horizontally long plate 3 tries to rotate around the horizontal support shaft 5, the force is transferred to the connecting member 7.
is transmitted to the worm wheel 9 via. Since the worm wheel 9 cannot rotate the worm gear 10,
The horizontally long plate 3 remains in a stopped state. Therefore, even when the wind blows, it can fully fulfill its role of blocking light and blindfolding.

In addition, sufficient lighting can be obtained when necessary.
