Abstract

The utility model relates to an improvement of the structure of a windproof umbrella, comprising umbrella ribs which form an umbrella frame, and an umbrella cover for shielding rain. The structure of the umbrella frame is that the upper end of a main rib is provided with an upper fixed head, and the main rib below the fixed head is provided with a moveable head which can axially move along the main rib. The periphery of the upper fixed head is radially pivoted with a plurality of supporting ribs. An inner sheath and an outer sheath which form an appropriate distance are sheathed and fixed on the proper positions of the supporting ribs. The surfaces of the supporting ribs between the inner sheath and the outer sheath are provided with a middle butterfly. The moveable head is composed of a middle fixed head which is integrated with a sheath penetrating the middle of a lower fixed head. The periphery of the middle fixed head is radially pivoted with a plurality of supporting ribs which are connected with the middle disk. The periphery of the lower fixed head is radially pivoted with a plurality of drawing springs which are fixed on the corresponding ends of the supporting ribs. Composed of the structure, the umbrella frame can damp the wind to avoid being broken in condition that an umbrella is over-opened.

Description

The wind-proof umbrella architecture advances

Technical field

The utility model relates to the wind-proof umbrella structure, particularly can guarantee fully powerful wind-force blow cause under the situation of turning over umbrella, can avoid this umbrella frame to produce the purpose design of fracture.

Background technology

See also Fig. 5 and shown in Figure 6, common people use umbrella, are to include umbrella frame 3 that constitutes umbrella frame and the umbrella cover of using as screening rain 4; Umbrella frame 3 structures wherein are to be provided with on one fixing 32 in the upper end of a main bone 31, and are provided with one at last a main bone 31 of fixing below 32 and can make axially movable movable head 33 along main bone 31; The above-mentioned periphery that should go up fixing 32 be a plurality of fulcra 31 that are pivoted radially, and in fulcra 31 suitable distances wear butterfly 34; Above-mentioned this movable head 33, its by in fixing 331 with lower fixed head 332 in the middle of wear central siphon 333 and do one-body molded institute and forms, in fix 331 and lower fixed head 332 between central siphon 333 surfaces then wear a spring 35; Above-mentioned should in fixing 331 periphery be a plurality of the support bones 36 that are pivoted radially and be connected to an end mutually with middle butterfly 34, and fixing 332 periphery be pivoted radially a plurality of extension springs 37 and a support bone 36 corresponding scoop out mutually to hold fix.

By the composition of said structure, common people can run into a common puzzlement during enforcement, promptly attack when umbrella struts and runs into random wind, and this powerful wind-force acts on the situation that " turning over umbrella " often takes place on the umbrella cover, and causes the damage of umbrella frame fracture.

For this reason, the utility model is that the umbrella frame that turns over umbrella easily when running into high wind based on aforementioned general umbrella and the caused existing shortcoming that ruptures is improved, make it can guarantee fully turning under the situation of umbrella when umbrella runs into powerful wind-force, the umbrella frame of this umbrella still can not cause the structure of fracture, reaches the useful life period of guaranteeing umbrella.

Summary of the invention

Main purpose of the present utility model is to be to provide a kind of wind-proof umbrella structure, overcomes the above-mentioned shortcoming of existing product.

For achieving the above object, solution of the present utility model is: a kind of wind-proof umbrella architecture advances, and it is to include umbrella frame that constitutes umbrella frame and the umbrella cover of using as screening rain; Umbrella rib structure wherein is that fixedly head is set in the upper end of a main bone on one, and the main bone below last fixing head is provided with one and can does axially movable movable head institute common composition along main bone; The above-mentioned periphery that should go up fixing head is a plurality of fulcra that are pivoted radially; Cover solid two inside and outside sleeve pipes that form suitable distances in the appropriate location of these fulcra prop up the bone surface butterfly in that then is pivoted between inside and outside sleeve pipe.

Further, this movable head wherein, its by in wear central siphon in the middle of fixing head and the lower fixed head and do one-body molded institute and form; Wherein should in a fixing periphery be a plurality of the support bones that are pivoted radially and connect with middle butterfly, and the lower fixed head periphery is a plurality of extension springs that are pivoted radially and fixes with support bone photo corresponding end.

It is to utilize extension spring to cooperate the formed buffer distance of middle butterfly that can do the front and back displacement, is turning under the situation of umbrella and reach this branch's umbrella frame, and available buffer wind-force is avoided the umbrella frame fracture.

Other purpose of the present utility model and function will be more clear after cooperating following diagram and being described further.

The specific embodiment

See also Figure 1 and Figure 2, wind-proof umbrella architecture advances provided by the utility model is to include umbrella frame 1 that constitutes umbrella frame and the umbrella cover of using as screening rain 2; Umbrella frame 1 structure wherein is to be provided with on one fixing 12 in the upper end of a main bone 11, and is provided with one at last a main bone 1 of fixing below 12 and can makes axially movable movable head 13 along main bone 1; The above-mentioned periphery that should go up fixing 12 is a plurality of fulcra 14 that are pivoted radially, and at solid two the inside and outside sleeve pipes 15,15 ' that form suitable distances of the appropriate location of fulcra 14 cover, the butterfly 16 in that then is pivoted of the fulcra 14 between two sleeve pipes 15,15 '; Above-mentioned this movable head 13, its by in fixing 131 with lower fixed head 132 in the middle of wear central siphon 133 and do one-body molded institute and form, wherein should in fixing 131 periphery be a plurality of the support bones 17 that are pivoted radially and connect with middle butterfly 16, and lower fixed head 132 peripheries be pivoted radially a plurality of extension springs 18 with prop up support bone 17 corresponding ends and fix.

See also Fig. 3 and shown in Figure 4, composition by above-mentioned the utility model structure, when high wind by the below of umbrella blow interlock when causing umbrella cover 2 up to turn over the up perk of support bone 17 of establishing of seam mutually, at this moment, should 16 contractilities of middle butterfly middle butterfly 16 be located to be displaced to interior pipe box 15 places by outer tube 15 ' by extension spring 18, so under the situation that causes so-called " turning over umbrella " phenomenon, can reach and guarantee that these fulcra 14 can not produce fracture damage; And when desiring to fold umbrella, when can leave behind central siphon 133 related movable head 13 down in the interlock butterfly 16 be moved to outer tube 15 ' and impel an extension spring 18 and a support bone 17 down to bring together.
