A continuously extruded profile sash and frame each having an integral rigid hinge thereon. The device comprises an operable hinge system wherein the load bearing hinge mechanics are extruded as an integral part of the extruded frame member and of the extruded sash moving panel, the sash and frame can each have a cell structure for increased structural integrity and thermal insulating capacity. A punch press may be used to create the male knuckle and female hinge components. At least one hinge pin can be inserted into the cylindrical cavity and run the length of the hinge. Panel and frame members include arcuate sides.
摘要:
An aerodynamic flying device combines features of a flying disk and a boomerang. The device uses a closed dome flying disk with one or more cambered wings attached to the disk. The wings have their leading edges facing in the direction of rotation of the disk. The wings may be asymmetrically cambered or may be symmetrically cambered about the center line of each wing. An outer ring is attached to the outer edges of each wing. A downwardly dependent curved rim runs along the outer periphery of the device with a discontinuity of the rim occurring along the joinder line whereat each wing attaches to the disk. Another discontinuity of the rim may occur along a portion of the trailing edge of each wing.
