Abstract

The utility model relates to a wind proof umbrella structure composed of main umbrella frame 1, a pivot block 2, a main umbrella tail frame 3, and an auxiliary umbrella tail frame 4, wherein, the utility model makes use of the design of the pivot block and is matched with bent designs of the main umbrella tail frame and the auxiliary umbrella tail frame; thus, the umbrella cloth has resistance and support functions when suffered form wind blowing; the utility model provides returning elasticity, which prevents an umbrella cover from turning outward to achieve the goal of wind resistance.

Description

A kind of wind-proof umbrella structure

The utility model relates to the parachute kit class, particularly a kind of wind-proof umbrella structure.

Known from institute, the umbrella frame of the double-deck umbrella cloth of general folding formula is constructed as accompanying drawing 1 to shown in the accompanying drawing 3, mainly be to organize separately in the articulated section of main umbrella skeleton group A to close with joint portion B, and joint portion B provides umbrella cauda C chimeric, form the form that supports, this design only utilizes combining of joint portion B and umbrella cauda C, when wind-engaging blows, umbrella cauda C is upturned, because stressed position is the interface at umbrella cauda C and joint portion B, so be easy to generate the situation of warpage even fracture, in addition, the chimeric of umbrella cauda C and joint portion B only gone up the protruding oblique sheet D that is provided with by umbrella cauda C, also is very easy to damage, causes coming off of umbrella cauda C.

The purpose of this utility model is exactly that umbrella frame at the double-deck umbrella cloth of above-mentioned general folding formula exists shortcoming, and a kind of wind-proof umbrella structure is provided, and the multiple stressed strong point is provided, and obtains effective back stretch, can avoid turning up or rupturing of umbrella frame.

The technical solution of the utility model:

According to the purpose of this utility model, provide a kind of wind-proof umbrella structure, main design by pivot joint block, cooperate the bending design of main chute coccyx and secondary umbrella coccyx, make umbrella cloth when wind-engaging blows, have the drag supporting role, and the elastic force of answer is provided, and avoid umbrella cover to turn up, reach the windproof purpose.

Figure 11 is another embodiment schematic diagram of the present utility model.

A is that articulated section, B are that joint portion, C are that umbrella cauda, D are that protruding oblique sheet, 1 is that main umbrella skeleton, 11 is that first driving rod, 2 is that pivot joint block, 21 is that last aspect, 3 is that main chute coccyx, 31 is that second driving rod, 4 is that secondary umbrella coccyx, 41 is that the 3rd driving rod, 32 is that Curved Continuous folding part, 42 is a kink.

As accompanying drawing 4 to shown in the accompanying drawing 8, the utility model is by main umbrella skeleton 1, pivot joint block 2, main chute coccyx 3, secondary umbrella coccyx 4 constitutes, wherein main umbrella skeleton 1 is articulated by the outer end of first driving rod 11 with pivot joint block 2 in the outer end, establish with Curved Continuous folding part 32 the inner of main chute coccyx 3, pass the below of first driving rod 11, and inner second driving rod 31 that is fastened on the position at pivot joint block 2 medial extremitys, the inner of secondary umbrella coccyx 4 is made as the top that kink 42 passes first driving rod 11, make the inner be fastened on three driving rod 41 of position, promptly form whole umbrella rib structure at pivot joint block 2 middle section positions.

As shown in Figure 9, when being subjected to high wind and blowing, the swing that all can make progress a little of main chute coccyx 3 and secondary umbrella coccyx 4, at this moment, main chute coccyx 3 will push up first driving rod 11, under reaction force, make Curved Continuous folding part 32 be subjected to downward strength, and make main umbrella skeleton 1 downward, provide an integral body to be downward elastic force relatively; Simultaneously, also interlock second driving rod 31 is downward, make pivot joint block 2 also be subjected to downward power, and make the outer rim that cooperates its top plate face 21 will be to the secondary umbrella coccyx 4 of lower swing also toward pressing down, be that effective back stretch is provided, and above-mentioned when stressed, because the design of kink is to make umbrella coccyx and secondary umbrella coccyx obtain flexible stressed supporting role, can avoids it to be damaged or roll over and ruin.

As shown in Figure 10, directly form sleeve pipe at the tail end of pivot joint block 2 and close secondary umbrella coccyx 4 with bundle; As shown in Figure 11, establishing with downward extension 22 in the inner of pivot joint block 2, when being attacked by wind, be pressed into main umbrella skeleton 1, and effective back stretch is provided, is to reach the wind resistance purpose.
