Abstract

The utility model relates to an inflating and folding umbrella, which uses inflating air bags as a skeleton. The utility model is composed of an umbrella surface, an air bag for umbrella ribs, an air supporting bag, an air valve core, an air conducting pipe, an air chamber, a casing, etc., wherein, an inflating cylinder is composed of the air conducting pipe, a piston, and the air chamber, the middle between the air conducing pipe and the air chamber is spaced by the piston to form a gap as space for packing the umbrella surface and the air bags, and the air conducting pipe, the air chamber and the casing are used as a retractable umbrella handle. When the utility model is used, the air conducting pipe is pulled out from the air chamber, the umbrella surface and the air bags are opened, the air conducting pipe is pushed and pulled, and the utility model can be used when the air bags are inflated. After the use of the utility model, an air discharging plug is opened to discharge air in the air bags, and the umbrella surface is folded and winds the air conducting pipe to be pushed in the air chamber. The utility model has the advantages of low cost, compact structure, and portability.

Description

The air-filled foldable umbrella

The utility model relates to a kind of parachute kit.Specifically a kind of with the folded umbrella of air bag as support frame.

Present folded umbrella all with solid rigid materials such as metal or timber as support frame, fabric is as lining, therefore, the more volume in space after folding is big, is not easy to carry.Moreover existing parachute kit often all do not have packing tube, and is therefore, very inconvenient after drenching with rain.

It is umbrella frame with the air bag that the utility model provides a kind of, is lining with the high performance thin film material, more compact after folding, and with the novel parachute kit of one section umbrella handle as packing tube.

The technical solution of the utility model is such: the air-filled foldable umbrella is mainly by umbrella cover, umbrella head, valve inside, shell, air chamber, wireway, support air bag, compositions such as umbrella frame air bag.Wherein, wireway double as the 3rd joint umbrella handle, the air chamber double as packing tube and the second joint umbrella handle, shell double as first segment umbrella handle.Wireway is a tubulose, long 120-250mm, and external diameter 4-8 millimeter, internal diameter 1-4 millimeter, the one end is connected with piston, and piston external diameter is slightly less than air chamber, and there is a through hole at its center, and through-hole diameter and wireway internal diameter equate.The internal diameter of air chamber is 15-35mm, long 120-250mm, and it forms an inflator pump with air guide chamber and piston.In addition, between wireway and air chamber by piston space every the space that forms can be used as hold umbrella cover and lose heart after the space of air bag.The outer cover of air chamber shell.At the other end of the wireway umbrella head that is being tightly connected.The umbrella head is tubular, and a bleeder port is arranged at its top, and bleeder port diameter 1-5mm by the embolism sealing, is installed with several gas-distributing pipes respectively with isogonism around the umbrella head, and a umbrella frame air bag is being tightly connected respectively on each gas-distributing pipe.The umbrella frame air bag in a tubular form, the other end for the sealing, long 300-600mm is connecting a support air bag at the middle part of each air bag.Support air bag also is a tubulose, and the other end is what seal, and is connected on the connecting ring.Umbrella frame air bag and support air bag all can be had than high-tensile, high-air-tightness material by nylon light wall pipe, PET film or other and cause.Umbrella cover covers and is connected on the umbrella frame air bag.

During use, earlier umbrella head and wireway are extracted from air chamber, and opened and wrap up in umbrella cover and the air bag that is entangled on the wireway, the push-and-pull wireway makes piston reciprocating in air chamber then, is airbag aeration.Air, when treating that the gas intracapsular pressure acquires a certain degree, is drawn back wireway, air chamber and shell in valve inside enters air bag by wireway again, can use as umbrella handle.Dry after using up, open umbrella top bleeder port, drain air in the air bag,, be wrapped on the wireway, take in the air chamber with wireway again, then with the shell pushing sleeve on it again with umbrella cover and airbag fold.

Present technique compared with prior art because the employing air bag is made umbrella frame, and makes full use of the unnecessary space in the umbrella, therefore has compact conformation, simple, and portable characteristics, cost are also very cheap.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a umbrella header structure schematic diagram.

Among Fig. 1,1 is umbrella cover, is made by fabric, PVC, PET film or other equivalent materials.2 is the umbrella head, and available aluminium, copper and engineering plastics or other equivalent materials are made.3 is valve inside, is placed in the joint of umbrella head and wireway 4.4 is wireway, that is is the 3rd joint umbrella handle of folded umbrella, in a tubular form, and its long 120-250 millimeter, diameter 4-10mm, wall thickness 1-3mm.Available metal, engineering plastics or other equivalent materials are made.5 is the support air bag connecting ring, and 6 is air chamber, and also in a tubular form, the second joint umbrella handle of holding concurrently also is the packing tube of folded umbrella simultaneously, its long 120-250mm, and diameter 15-33mm, wall thickness 0.5-2mm can be made by metal, engineering plastics.7 is piston, and its diameter is slightly less than the internal diameter of air chamber 6.Wireway 4, piston 7 and air chamber mutual group become an inflator pump.8 is shell, also in a tubular form, and double as first segment umbrella handle, long 120-250mm, diameter 16-35mm, wall thickness 0.5-2mm also can be made by metal, engineering plastics or other equivalent materials.9 is the air inlet of inflator pump, and 10 is support air bag, and 11 is the umbrella frame air bag, and the both is hose-like, diameter 10-30mm, and 20 microns-150 microns of wall thickness, the both can be by nylon book pipe, and PET film or other have high-tensile, and the thin material of high-air-tightness is made.

12 is the bleeder port embolism among Fig. 2, and 13 is bleeder port, and 14 is gas-distributing pipe, and 15 is the valve inside rubber case.

The umbrella cover of air-filled foldable umbrella can print various high-definition screens, and shell can be done various polishings and decorate processing, makes it can be used as exquisite gift and sells.Also can be made into lip pencil sells.
