Abstract

The utility model relates to an improved umbrella frame mainly comprising a main frame, a middle frame, a support frame, and folding umbrella frames of an inner connection frame and an elastic connection frame. The utility model is characterized in that the inner connection frame is a bent rod-shaped elastic rod body. When the umbrella is expanded to open or is folded, the elastic inner connection frame and the elastic connection frame generate proper deformation to obtain effect of elastically and smoothly expanding and closing. Simultaneously, after the umbrella is opened to generate an umbrella flower, the middle frame and an outer main body have elastic buffering function under the elastic deformation of the elastic inner connection frame. The utility model can effectively ensure the umbrella frame that is not bent or damaged.

A kind of improved umbrella rib skeleton, mainly include main bone, its the inner is connected in nest, the nearly inner place of bone during the outer end is articulated in, the inner coupling device of the terminal and outer main bone of middle bone articulates, articulate in main bone middle section and fulcra in addition, the inner of fulcra is connected on the lower nest, and place, the nearly outer end of fulcra articulates with internal connecting rib one end, internal connecting rib another end and middle bone are inner to be articulated, cooperate elasticity linking bone two ends to be connected to the nearly inner place of main bone and the inner place of outer main bone, it is characterized in that: this internal connecting rib is a sweeping shaft-like elasticity body of rod again.

The outer section of main bone corresponding to this elasticity internal connecting rib interlude place place establish one limit this elasticity internal connecting rib the umbrella frame umbrella stand launch with folding in, the limit element that slide in the space in the main bone trough.

This limit element is for directly being bent to form by the stage casing moulding of main bone or being a tubulose heat shrinkage film.

The utility model is provided with an elasticity linking bone between inboard place, main bone outer end and the inner coupling device of outer main bone, and is provided with an elasticity internal connecting rib between inboard place, fulcra outer end and middle bone end, as the combination that links between each umbrella frame.So that umbrella rib skeleton upon deployment, can be slowed down by the elasticity of the inside and outside linking bone of elasticity sweeps away, and obtains to take down the exhibits more smoothly, and can avoid middle bone or internal connecting rib to produce bending distortion or brisement when high wind blows the parachute-opening flower, reaches the purpose of durable use.

Of the present utility model simple in structure, this parachute kit is being taken down the exhibits or parachute-opening when flower, the elastic bending deflection that its elasticity internal connecting rib cooperates the elasticity linking bone to be produced, can eliminate the pressure of pushing between each umbrella frame, it is more smooth and easy that parachute kit is taken down the exhibits, and guarantee that internal connecting rib and middle bone do not produce permanent bending distortion or rupture failure, and obtain the effect of durable use.

Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.
