DETAILED DESCRIPTION OF THE INVENTION

[0025] The present invention, a collapsible canopy, includes a covering 1, a framework 2, which further includes a cross hinge 3, center members 4, U-shaped slide brackets 5, U-shaped slide brackets 6, side members 7, cantilever members 8, upside hinges 9, downside hinges 10, scissors frames 11, supporting members 12, springs 13, and holes 14.

[0026] Referring to FIG. 1 and FIG. 2, which illustrate the first embodiment of the present invention. Covering 1 is put on framework 2. Each of the four sides of framework 2 comprises two scissors frames 11 to form a foldable cross beam. Each scissors frame 11 comprises two cross pieces 8 hinge connected to each other in the midway. Two ends of each scissors frame 11 are respectively connected to two corresponding ends of the other scissors frame 11 at the same side by means of hinge connection. The other two ends of each scissors frame 11 are respectively connected to the two corresponding ends of the scissors frame 11 on the abutting side by means of hinge connection, thus forming two flexion points. Each of the four supporting members passes through the downside hinges 10 thereof to form a sliding fit construction. The top end of each supporting member is provided with an upside hinge 9 in a fixed fashion. Center members 4, side members 7, and cantilever members 8 are connected to each other by slide brackets sets composed of U-shaped slide brackets 5 and 6. The other side of each center member 4 is connected to cross hinge 3 by means of hinge connection. The other side of each side member 7 is connected to upside hinge 9 by means of hinge connection. The other side of each cantilever member 8 is connected to downside hinge 10 by means of hinge connection.

[0027] Referring to FIG. 4, the open end of the U-shaped slide bracket 6 and the cantilever member 8 are connected to the center member 4 that passes through the bottom space of another U-shaped slide bracket 5 by means of hinge connection side member 7 passing through the bottom space of slide bracket 6 connected to the open end of another slide bracket 5 by means of hinge connection.

[0028] Referring to FIG. 5, each of the four branches of the cross hinge 3 right-angled to each other is provided with a hinge hole 31.

[0029] Referring to FIG. 8 and FIG. 9, which illustrate the second alternate embodiment of the present invention. When the framework 2 is extended, the protruding end of spring 13 inside the hollow support member 12 where a down side hinge is provided passes through the wall of the hollow support member 12 and is received by the hole 14 on the downside hinge 10. The construction of other parts of this embodiment of the canopy structure is same to that of the first embodiment of the present invention.

[0030] FIG. 6 and FIG. 7 illustrate the third alternate embodiment of the present invention. FIG. 6 reflects a cone-shaped roof structure, while FIG. 7 reflects a dome-shaped roof structure. The difference between the cone-shaped roof structure and the dome-shaped roof structure lies in that the length of cantilever member 8 of the dome-shaped roof structure is shorter than that of the cone-shaped roof structure. Different roof structures are provided with corresponding coverings 1 of different shapes. The construction of other parts of the canopy structure is same to that of the second embodiment of the present invention.

[0031] A fourth alternate embodiment of the present invention includes a canopy structure of which the height can be raised or lowered when needed by connecting the lower end of each hollow support member 12 with a telescopic tube. The construction of other parts of the canopy structure is same to that of the second or the third embodiment of the present invention.

[0032] Referring to FIG. 3, the collapsible canopy structure can be stricken simply by removing the covering 1 and folding the framework 2.

[0033] It is obvious that the present invention has advantages over the prior art. From the technical method described above one can know that a collapsible canopy comprises a covering and a collapsible framework on which the covering is put, each of the four sides of the collapsible framework comprises two scissors frames forming a collapsible cross beam, each scissors frame comprises two pieces of cross pieces hinged to each other in the midway, The other two ends of each scissors frame are respectively connected to the two corresponding ends of the scissors frame on the abutting side by means of hinge connection, thus forming two flexion points, each of the four supporting members passes through the downside hinge thereof to form a sliding fit construction, and center members, side members, and cantilever members are connected to each other by slide brackets sets. All members comprising the framework of the canopy are connected to each other either by slide fits or hinge connections, thus making it easy to pitch or strike the canopy simply by extending the framework and put up the covering or by removing the covering and folding the framework, and also making it convenient to carry and transport.

[0034] From the above it can be known that the collapsible canopy of the present invention has significant improvements both in the construction and the operation.

[0035] Accordingly, the above described are only the preferred embodiments of the present invention which does not in any way limit the present invention. It should be appreciated that any modifications or changes may be made according to the preferred embodiments of the present invention without departing from the scope of technical solutions described herein.
