JPH083226B2 - Openable dome roof - Google Patents

Description

FIELD OF THE INVENTION The present invention relates to a retractable dome roof having a plurality of movable panels.

Conventional technology The circular openable dome type roof that has been proposed in the past is
For example, as shown in FIG. 7, six movable panels 33 that are slidable along the arch beams 31 that are arranged in the radial direction by shifting from the top by 60 ° and that can cover the top opening 32.
It has. Each movable panel 33 includes rails 34, 3 arranged along a fixed panel around the arch beam 31 and the ceiling opening 32.
5, the traveling carriages 36, 37 provided on the lower surface of the movable panel 33 are guided, and the movable panel 33 is connected to the panel drive winch via a wire rope along the arch beam, and in a fully closed position and a solid line shown by a virtual line. It is opened and closed to the fully open position shown.

Problems to be Solved by the Invention According to the above-described conventional configuration, when the movable panel is closed from the fully open position, the rising gradient of the movable panel is large.
This requires an extremely large driving force, which limits the weight of the movable panel and narrows the aperture ratio.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and provide an openable dome type roof that can reduce the pulling force of a movable panel.

Means for Solving the Problems In order to solve the above problems, the present invention provides a fixed panel having a top opening formed on a top of a spherical roof, and a plurality of slidable movable panels covering the top opening. In an openable dome type roof equipped with and, a linear slanted beam extending downward from the vicinity of the edge of the top opening along the tangential direction of the roof is provided, and a rail for guiding the movable panel is provided on the upper surface of the slanted beam. It is arranged.

Action According to the above configuration, the slope of the inclined beam can be made smaller than the slope of the fixed panel skirt, so that the force for pulling up the movable panel on the inclined beam when fully closing from the fully open position can be made smaller than in the conventional case.

Embodiment An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 2 to 5, this dome-shaped roof 1 is formed in a spherical shape with a circular shape in plan view, and has a fixed panel 4 having a circular top opening 3 centered on the top 2 and a top 2. Six arc-shaped movable beams 5 are provided, which are equally divided into six at the center and cover the top opening 3, and are arranged at equal angles around the top 2 to reach the ground. , Fixed panel 4
And the movable panel 5 is supported.

Outside the fixed panel, tilted beams 7 are provided which extend downward downward at an angle of inclination of about 30 degrees with respect to the horizontal plane in the tangential direction of the arched beams 6. It is connected to the vicinity of the top opening 3 at the fixed panel 4 mounting part of
Support base 8 whose base end is formed outside the hem of the fixed panel 4
Supported by. Further, a center rail 9 that is continuous from an arc shape to a straight line is provided from the upper end of the arch beam 6 to the lower end of the inclined beam 7 via the connecting portion between the arch beam 6 and the inclined beam 7. Further, a pair of left and right guide slanted beams 10 parallel to the slanted beam 7 are disposed on both sides of the slanted beam 7, and side rails 11 are disposed on the upper surfaces of the guide slanted beams 10, respectively.

As shown in FIGS. 1 and 4, the movable panel 5 is provided with a center carriage 12 having traveling wheels guided by the center rails 9 on the lower surface of the front end and the lower surface of the base end on the center line along the arch beam 6. Side carriages 13 are arranged so as to be swingable around a horizontal axis orthogonal to the main rail 9, and the side wheels 13 each having traveling wheels guided by the side rails 11 are arranged on the lower surfaces of both side corners of the movable panel 5. Set up. Opening / closing winches 14 are provided outside the support base 8 at the base end of the inclined beam 7, and as shown in FIG. 6, a movable sheave 15 provided at the tip of the movable panel 5 and a top. The open / close wire rope 19 wound around the stationary sheave 17 disposed on the second center member 16 and the guide sheave 18 disposed on the arch beam 6 and the inclined beam 7 is wound around the winch drum 14a. The fully closed position (a) shown in FIG. 2 and the third position
It is slid between the fully open position (b) shown in the figure.

According to the above configuration, when the movable panel 5 is pulled up from the fully open position (b) to the fully closed position (a), the inclination of the inclined beam 7 is about 30 ° and the hem inclination α ° of the fixed panel 4 (first Since it is smaller than about 62 ° in FIG. 5, the pulling force is smaller than the conventional pulling along the fixed panel 4.

Although the inclined beam is connected to the arch beam according to the above-described embodiment, the arch beam itself may be composed of the arch beam above the connecting portion and the inclined beam continuous to the arch beam.

As described above, according to the present invention, the movable panel is
Since the linear slide is performed from the vicinity of the edge of the top opening along the tangential slanted beam, when the movable panel is slid in the fully closed direction from the fully open position on the slanted beam, the pulling gradient of the movable panel is the same as before. It is smaller and requires less pulling force. Therefore, the drive equipment for the movable panel can be reduced in size and weight, the cost can be reduced, and conversely, the movable panel can be made larger and the aperture ratio can be increased with the same equipment.
