Abstract

The utility model relates to an improved folding structure which comprises first umbrella bones(11) which extend outside from an upper nest(1), second umbrella bones(2), third umbrella bones(13) and umbrella tail bones(14). The inner end of the umbrella supporting bones(21) is pivoted at the active nest(2), and the outer end is pivoted at the junction(121) between the second umbrella bones(12) and the third umbrella bones. An elastic supporting bone(3) is arrayed into a line, and the inner end is connected with the outer end of the umbrella supporting bone, and has a small space with the junction(121), while the outer end is connected with the inner end of the umbrella tail bones(14); besides, a concave part(131) is arranged at an appropriate position of the third umbrella(13) and connected with a clip ring(14). The utility model is arranged at the outer end of the umbrella supporting bones and the inner end of the umbrella tail bones through the elastic supporting bones, a larger arc can be formed when the umbrella is folded, and thus the folding of the umbrella is convenient; and an upward elasticity can be provided, making the third umbrella bone form an upward arc shape to extend the umbrella cloth effectively, thus can realize convenient and practical function by means of a simplified structure.

Description

A kind of improvement of rolling over the umbrella structure

The utility model relates to the parachute kit class, particularly a kind of improvement of rolling over the umbrella structure.

Common folding umbrella is when closing one's umbrella, its umbrella coccyx still upwards folds, use the volume after dwindling it and folding, the folding umbrella of this structure is to present complete umbrella cloth radian when making parachute-opening, and the certain folding when closing one's umbrella, must be articulated with a movable block 23 in the outer end of its secondary umbrella frame 22 in addition, and be articulated with the inner of umbrella coccyx 14, to shown in the accompanying drawing 3, the angle of mat movable block 23 changes, and the application of parachute kit is provided as accompanying drawing 1, this kind structure is comparatively complicated, inconvenience on making and assembling, and be easy to generate fault, still remain to be improved.

The purpose of this utility model is exactly the shortcoming that exists at above-mentioned common folding umbrella, and a kind of improvement of rolling over the umbrella structure is provided.

Technical conceive of the present utility model:

According to the purpose of this utility model, a kind of improvement of rolling over the umbrella structure is provided, mainly be to establish to be connected with in the outer end of umbrella gill and the inner of umbrella coccyx, when closing one's umbrella, can form big radian, be convenient to close one's umbrella with elasticity fulcra, and during parachute-opening, elastic force upwards is provided, makes the 3rd umbrella frame form bent arc, with effective expansion umbrella cloth, not only manufacturing and easy to assembly, and be difficult for breaking down.

Accompanying drawings structure of the present utility model and embodiment:

Fig. 1 is common folding umbrella structural plan figure.

Fig. 2 is the parachute-opening plane of Fig. 1.

Fig. 3 is Fig. 1 part-structure schematic perspective view.

Fig. 4 is a part-structure schematic perspective view of the present utility model.

Fig. 5 is a parachute-opening planar structure schematic diagram of the present utility model.

Fig. 6 is the planar structure schematic diagram that closes one's umbrella of the present utility model.

1 is that last nest, 11 is that first umbrella frame, 12 is that second umbrella frame, 13 is that the 3rd umbrella frame, 14 is that umbrella coccyx, 2 is that movable nest, 21 is that umbrella gill, 22 is that sub-framework, 23 is that movable block, 3 is that elasticity fulcra, 4 are clasp.

As accompanying drawing 4 to shown in the accompanying drawing 6, the utility model includes first umbrella frame 11, second umbrella frame 12, the 3rd umbrella frame 13 and the umbrella coccyx 14 that outwards extends in regular turn from last nest 1, the inner of its umbrella gill 21 is to be articulated in movable nest 2, and the outer end then is articulated in the joint portion 121 of 13 of second umbrella frame 12 and the 3rd umbrella frames; Other is provided with elasticity fulcra 3, make its inner be incorporated into the place, outer end of umbrella gill 21, has a bit of spacing with joint portion 121, its outer end then is incorporated into the inner of umbrella coccyx 14, be provided with a recess 131 in the 3rd umbrella frame 13 appropriate locations in addition, provide combination one clasp 4, be affixed on the downside of the 3rd umbrella frame 13 to fasten three elasticity fulcra 3.

Shown in accompanying drawing 5 and accompanying drawing 6, the utility model is by the elastic reaction of elasticity fulcra 3, when parachute-opening as shown in Figure 5, have complete last cambered surface, and when closing one's umbrella, as shown in Figure 6, have the space of folding, and under the curved arc degree of elasticity fulcra 3, parachute kit can be folded completely.

The utility model is simple in structure, makes with the assembling facility, is difficult for breaking down, and has good economy.
