Embodiment Construction

[0010] Referring to FIGS. 1 to 5, an umbrella frame 1 comprises a lower runner 28, a main shaft 30 inserted through the lower runner 28, an upper runner 29 disposed on a top end of the main shaft 30, and a plurality of stretching frames 2.

[0011] Each of the settings frames 2 has a stretcher 23, a connection plate 24, an elastic rod 25, a connector 26, a distal rod 27, a long rib 21, and a short rib 22.

[0012] The stretcher 23 is connected to the lower runner 28.

[0013] The short rib 22 is connected to the upper runner 29.

[0014] The stretcher 23 has a distal protrusion 231 and a downward lobe 232 having a round hole 2321.

[0015] The connection plate 24 has a first end protrusion 241 and a second end protrusion 242.

[0016] The connector 26 has an end notch 261, an end hole 263 to received the distal rod 27, and a lower protruded block 262 having a circular hole 2621.

[0017] The long rib 21 has an end protruded block 213 inserted in the circular hole 2621 pivotally, an upper pressing...

Abstract

An umbrella frame has a lower runner, a main shaft, an upper runner, and a plurality of stretching frames. Each stretching frame has a stretcher, a connection plate, an elastic rod, a connector, a distal rod, a long rib, and a short rib. The connection plate has a first end protrusion and a second end proton. The connector has an end notch, an end hole, and a lower protruded block having a circular hole. The long rib has an end protruded block inserted in the circular hole, an inner protruded bar having a first through aperture, and an outer protruded bar having a second through aperture. The elastic rod is inserted through a spacing defined by the upper pressing bar and the long rib The short rib has a distal protruded block, an upper protruded bar having a round aperture, and a lower lobe having a circular aperture. The elastic rod has two end hooks. The elastic rod is hooked in the end notch and the round aperture. The distal protruded block is inserted in the first through aperture. The second end protrusion is inserted in the second through aperture. The distal protrusion is inserted in the circular aperture.

Description

FIELD OF THE INVENTION [0001] The preset invention relates to an umbrella frame, and more particularly to an umbrella frame which has a plurality of stretching frames to be used for a long period of usage without easily breaking. BACKGROUND OF THE INVENTION [0002] A conventional umbrella frames is made of metals. A joint which is disposed between a long rib and a short rib is easily broken after a long period of usage. SUMMARY OF THE INVENTION [0003] An object of the present invention is to provide an umbrella frame which has a plurality of stretching frames to be used for a long period of usage without easily breaking. Therefore, a period of usage is elongated. [0004] Accordingly, an umbrella frame comprises a lower runner, a main shaft inserted through the lower runner, an upper runner disposed on a top end of the main shaft, and a plurality of stretching frames. Each of the stretching has a stretcher, a connection plate, an elastic rod, a connector, a distal rod, a long rib, and ...
