Abstract
An openable dome-shaped roof structure is provided upon a circular side wall and comprises a crescent-shaped fixed roof section, a pair of pivotable roof sections and a pair of slidable roof sections. Each pivotable roof section is connected to a respective slidable roof section by a pivot at peripheral end portions thereof so that the pivotable roof section can rotate to a position above the slidable roof section. The slidable roof sections are each provided to be able to rotate toward the upper surface of the fixed roof section about the center of the circle of the side wall.
Claims10
An openable dome-shaped roof structure comprising:
- a peripheral side wall;
- a first slide guide means provided upon said side wall along a circle;
- a crescent-shaped fixed roof section having an arc-shaped outer periphery fixedly supported by said side wall and an arc-shaped inner periphery;
- a second slide guide means provided upon said fixed roof section along a circular arc which is concentric with said circle;
- a pair of slidable roof sections provided above the level of said fixed roof section and symmetrically arranged relative to a first diametral line of said circle, which line divides said slidable roof sections into equal two parts, said slidable roof sections meeting with each other at a first point where said diametral line intersects with said circle at the opposite side of said fixed roof section, each said slidable roof section being defined by an outer arc portion extending along said circle from said first point to a respective second point where said arc-shaped outer and inner peripheries of said fixed roof section meet with each other, an inner arc portion extending along said arc-shaped inner periphery of said fixed roof section from said second point to a third point where said second slide guide means terminates, and a substantially linear portion extending from said first point to said third point;
- a third slide guide means provided upon each said slidable roof section along and near said inner arc portion thereof;
- a pair of pivotable roof sections symmetrically arranged relative to said diametral line in such a manner that said pivotable roof sections close a space of a dome-shaped roof not covered by said fixed roof section and said slidable roof sections, each said pivotable roof section being provided above the level of a respective said slidable roof section and pivotably connected thereto at a position adjacent said first point;
- means for pivotably moving said pivotable roof sections upon said slidable roof sections along said third slide guide means;
- and
- means for slidably moving said slidable roof sections upon said fixed roof section along said first and second slide guide means.
