Description

[Detailed description of the invention] This invention relates to a retractable dome equipped with windows for ventilation and lighting.

Conventional retractable domes have a fixed lower half and a movable upper half made up of multiple parts, and ventilation is achieved by sliding the upper half vertically along the dome surface to open and close the dome. However, in the case of large retractable domes, the opening/closing mechanism for the upper half and stress analysis are complicated, so it has not been carried out much to date.

This idea was developed in view of the above circumstances,
By providing multiple openings in the dome in a staggered manner in the circumferential direction of the dome and attaching movable panels that slide within the opening plane to the openings, stress analysis of the opening/closing mechanism of the movable panels and the dome structure can be performed. It is designed to be simple and clear, and allows ventilation, lighting, and sound to be easily and freely adjusted as necessary.

Hereinafter, this invention will be explained with reference to an illustrated embodiment. A plurality of openings 1, . . . are formed in a staggered manner in the circumferential direction of the dome A. Lighting panels 2, . . ., which slide horizontally within the opening planes of the openings 1, .

Guide ribs 3, . . . , which are continuous in the horizontal circumferential direction of the dome A, are attached to the upper and lower edges of the openings 1, . . . , respectively, and guide ribs 3, . Guide grooves 4, 4 continuous in the horizontal circumferential direction are formed, respectively.

Vertical rollers 5, 5 and horizontal rollers 6, which slide on the upper surface of the guide rail 3 and within the guide groove 4, respectively, are attached to the lower end surface of the movable panel 2. The vertical rollers 5, 5 are rotated by a motor 7, and the rotational speed thereof is adjusted by a transmission 8. A pinion 9 is attached to the vertical roller 5 and meshes with a rack 10 attached to the upper surface of the guide rib 3. The rack 10 is continuous in the horizontal circumferential direction of the dome A.

Further, a horizontal roller 6 that slides within the guide groove 4 is also attached to the upper end surface of the movable panel 2.

In addition, when sliding the movable panel 2,...
Horizontally movable panels 2, . . . are interconnected and simultaneously slid by one drive device 11. (See Figure 3) Alternatively, the motor 7 can be attached to each movable panel 2,..., respectively, and each movable panel 2,...
…slide alone. (See Figure 4) This invention consists of the above-mentioned structure, and the following effects can be expected.

Stress analysis of the movable panel opening/closing mechanism and dome structure can be easily and clearly performed.
As a result, the structure of the opening/closing mechanism can be simplified, and the structure of the dome structure can be easily and accurately designed.

Not only can you get uniform sunlight, but you can also freely adjust ventilation, lighting, and sound as needed.
