Ceiling hinge assembly
An improved hinge assembly disclosed in this invention makes the installation more convenient by redesigning the single-axle hinge structure, which comprises a base and a rotary rod, and the connection between the rotary rod and the base is improved by replacing the protruded axle at one end of the original rotary rod with a connecting groove, and makes the pivotal connection of the rotary rod easier and the connection more secure.
The present invention relates to an improved ceiling hinge assembly, more particular to an improved single-axle ceiling hinge assembly that makes the installation easier.
BACKGROUND OF THE INVENTIONIf a glass door is built, most constructions usually adopt floor hinges as building materials in order to save time and effort for the construction. However, a dark chamber must to be installed at the floor of the construction before such construction is taken place. When the floor hinge is in use, the floor hinge has to keep a gap between the door and the floor. Therefore, an airtight strap is usually used to improve the situation of such gap. If we have to clean the floor, the airtight gap cannot stop the dirty water from flowing. If such hinge is used for a glass door, it is necessary to install a set of metallic bracket onto both upper and lower edges of the glass door before installing the hinge to facilitate fixing the glass door in a fixed position.
The feature of a frameless glass door resides on its good heat and sound insulation, but its pivotal connection is done by installing the floor hinge between the glass door and the frame. Therefore, there is a gap between the door and the floor, which will reduce the heat and sound insulation effect. The U.S. Pat. No. 5,077,864 disclosed a hinge installed on the side of a door, and the design of such hinge is divided into two sections; one section is fixed onto the door frame, and the other section is connected to the door panel, and the two sections of the hinge are pivotally coupled. The hinge is lubricated when needed to avoid rusting, and the rust makes the door uneasy to open. Furthermore, the installation of the hinge requires precision that may be affected by human factors. Therefore, it is necessary to adjust the hinge and the door, which may cause the correction and adjustment problems.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to improve conventional ceiling hinges that are uneasy to install and poor at its sealing function, and improve the ceiling hinge structure to provide a more convenient way of installing the hinge. The present invention relates to a single-axle design, comprising a base and a rotary rod coupled to the base, and the head of the rotary rod is designed as a connecting groove, which is coupled to the connecting axle of the base. Adjustment along the vertical direction can be made by rotating a screw on the rotary rod. The body of the rotary rod has a plurality of holes for connecting the door panel by fixtures.
