The umbrella frame of vertical frame umbrella

Technical field

The utility model relates to a kind of parts of parachute kit used in everyday, relates in particular to the improvement of umbrella rib structure, is applicable on vertical frame umbrella automatic or that hand is opened.

Background technology

In prior art, there is a kind of vertical frame umbrella that adopts more long bone to support umbrella cover, as vertical frame umbrellas such as 24K or 18K, can make that umbrella shape is more attractive in appearance after parachute-opening, structure is more stable, yet this vertical frame umbrella is because long bone is more, if every long bone all adopts an independent short bone to support, the umbrella frame quantity not only needing is many, and the nest body of umbrella also must be done very greatly to be large enough to hold more short bone, this can cause size of folded umbrella too large, inconvenience is collected and is carried, the problem that the weight of umbrella and cost increase.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of umbrella frame that reduces size of folded umbrella and can reduce the vertical frame umbrella of umbrella frame number of components.

The technical scheme in the invention for solving the above technical problem is, manufactures and designs a kind of umbrella frame of vertical frame umbrella, comprising: the pull bar being connected with described short bone for supporting the long bone of umbrella cover, the short bone that supports described long bone and outer end; The inner of described short bone and pull bar respectively with middle nest and the lower nest pivot joint of umbrella.

Described short bone comprises: first minute fulcra, second minute fulcra, at least one the 3rd minute fulcra and base portion.Described base portion the inner and middle nest pivot joint, this base portion is fixed in described first minute fulcra and second minute fulcra the inner, and within described the 3rd minute, fulcra are fixed on described pull bar outer end, and the outer end of described first minute fulcra, second minute fulcra and the 3rd minute fulcra is respectively connected a long bone.

The base portion of described short bone comprises the first pilum and second pilum of outside bifurcated, and the inner of this first pilum and the second pilum is articulated in a wherein pivot joint position of nest in umbrella after converging.

Described pull bar comprises the first pull bar and second pull bar of outside bifurcated, described the first pull bar outer end is connected with described the first adapter sleeve, described the second pull bar outer end is connected with described the second adapter sleeve, and the inner of this first pull bar and the second pull bar is articulated in a wherein pivot joint position of Umbrella runner after converging.

Described pull bar outer end is fixed with the first adapter sleeve, the second adapter sleeve and the 3rd adapter sleeve, described the first adapter sleeve and the second adapter sleeve are slidably socketed respectively outside described first minute fulcra and second minute fulcra, and described the 3rd adapter sleeve and described the 3rd minute fulcra are fixedly sleeved.

Described pull bar and the first adapter sleeve, the second adapter sleeve and the 3rd adapter sleeve are one-body molded.

Described the 3rd adapter sleeve is folded between the first adapter sleeve and the second adapter sleeve, and the described San branch position of bone is between first minute fulcra and second minute fulcra.

Under deployed condition, the inner end of described the 3rd minute fulcra is higher than the inner end of first minute fulcra and second minute fulcra, and the outer end of the 3rd minute fulcra is lower than the outer end of first minute fulcra and second minute fulcra; Under umbrella closing state, the outer end of described the 3rd minute fulcra than the outer end of first minute fulcra and second minute fulcra slightly to inside contracting.

Compared with the existing technology, each of the umbrella frame of vertical frame umbrella of the present utility model short bone includes three minutes fulcra, within every minute, fulcra connect respectively a long bone, the number that can greatly reduce thus the inner articulated section of short bone and pull bar, effectively reduces the radial dimension of middle nest and lower nest, thereby can reduce size of folded umbrella, facilitated carrying and collecting of umbrella, and can reduce umbrella frame number of components, and alleviate the weight of umbrella, reduce costs.
