Abstract

The utility model relates to an automatic folding umbrella, which is characterized in that a small umbrella rod (10) is gored upward by a lower power spring (16). A lower flange ring (9) is gored at a relevant position by an upper power spring (7), and the upper segment (2) and the lower segment (3) of an upper supporting frame are gored by the outer end of a lower supporting frame (8), and a framework is spread. The automatic folding umbrella has the advantages of small size of a self-opening folding umbrella, convenient carryover, convenient operation, simple structure and low cost, and the automatic folding umbrella can accomplish to automatically fold and close, and can relieve consumer's burden.

Description

Automatic folding umbrella

This is a kind of novel rainproof sunshade apparatus from opening from closing the folding umbrella.

That generally uses at present unfolds umbrella certainly, because volume is less, is easy to carry, and can open automatically again, uses more just, so be subjected to people's welcome, sales volume is more.But this oneself unfolds umbrella, must with the hands operate when folding, and is still convenient inadequately.In order further to provide a kind of more convenient rainproof sunshade apparatus to people, existing research and design a kind ofly can open the en-toutcas that closes automatically and can fold automatically.

This is that skeleton all is by three flange rings in upper, middle and lower from opening from closing the folding umbrella with the umbrella something in common of generally using now of unfolding certainly, and the three groups of fulcra in upper, middle and lower, inside and outside, (large and small) two umbrella bars and two power springs of being nested are formed.Difference is: existing the upper ramus two sections are not direct connections from unfolding umbrella, link to each other but be connected fulcra with one by lower support rib; In, the tension force of following two outer power springs of flange ring slides from lower to upper, and umbrella stand is opened automatically; The gamp bar last (outside), the umbellule bar is at down (interior), inner power spring up pushes up the gamp bar, elongates the umbrella bar.This is from opening from closing the folding umbrella, and the upper ramus epimere directly links to each other with hypomere; Middle flange ring maintains static, and the lower flange ring promotes from top to bottom by last power spring, drives umbrella stand and opens; The gamp bar is at down (outer), and the umbellule bar is at last (interior), by time long umbrella bar in power spring top.Describe in detail below in conjunction with embodiment:

Fig. 1 is the skeleton structure schematic diagram of this umbrella when opening, and Fig. 2 is the skeleton structure schematic diagram of this umbrella when folding, with reference to accompanying drawing: (1), be the upper flange ring; (2), upper ramus epimere; (3), upper ramus hypomere; (4), the tie point of upper ramus epimere and hypomere; (5), middle flange ring; (6), middle ramus; (7), go up power spring; (8), lower support rib; (9), lower flange ring; (10), little (interior) umbrella bar; (11), big (outward) umbrella bar; (12), scarce suitable for reading on the umbellule bar; (13), breach under the umbellule bar; (14), control button; (15), button spring; (16), following power spring; (17), handle of umbrella.

With reference to Fig. 1, when opened power spring (7) and (16) free Shen up and down, elongation was backed down in big umbellule bar (10) and (11), and lower flange ring (9) moves down by last power spring (7) and withstands on corresponding position.Middle ramus (6) is held the centre of lower support rib (8), and the inner of upper ramus hypomere (3) is withstood in the outer end of lower support rib (8), thereby struts umbrella stand.Control button is buckled in the breach under the umbellule bar (13), prevents to glide after umbellule bar (10) is under pressure to cause folding.

With reference to Fig. 2, when folding, the top of upper flange ring (1) is withstood, hold the hand of handle of umbrella (17) and pin control button (14) with thumb, make it throw off breach (13) under the umbellule bar, it is up mobile thereby drive gamp bar (11) to enforce handle of umbrella (17), simultaneously lower flange ring (9) is up pushed away, power spring (7) and (16) are compressed up and down, and in the time of in control button (14) is stuck in breach on the umbellule bar (12), power spring (7) and (16) are stuck up and down.Because lower flange ring (9) thus up move and up slide with the inner of lower support rib (8), and the centre of lower support rib (8) is withstood by middle ramus (6), its outer end is inevitable to move inward downwards, outer end at lower support rib (8) moves down the interior time receiving, the inner that must drive upper ramus hypomere (3) moves down, because the lower end of upper ramus epimere (2) is connected inner (4) point of upper ramus hypomere (3) place, therefore must tilt upward and past interior gathering in the outer end of upper ramus hypomere (3), control button (14) is buckled in the breach on the umbellule bar (12), and whole umbrella stand is folded together.As long as grasp handle of umbrella (17), moving control button (14) press...withes one's finger, make it to throw off breach on the umbellule bar (12), under the tension force effect of up and down power spring (7) and (16), umbellule bar (10) quilt is jack-up up, corresponding the moving down of lower flange ring (9), the outer end perk of lower support rib (8), thereby with upper ramus (2) and (3) jack-up, umbrella stand automatically springs open.This umbrella can be cancelled power spring (16) down, singly uses power spring (7), realizes automatic opening and closing; If lower flange ring (9) and gamp bar (11) are fixed together, depend merely on down power spring (16) and also can realize automatic opening and closing.

This from the advantage of opening from closing the folding umbrella is, it is little both to have kept the folded umbrella volume, and portable advantage can be opened again certainly from closing, and one-handed performance uses more conveniently, and it is simple in structure, and production cost is also low.

Claims (2)

1, a kind of folding umbrella that closes automatically of opening automatically, its skeleton is by upper flange ring (1), upper ramus epimere (2) and hypomere (3), middle flange ring (5), middle ramus (6), last power spring (7), lower support rib (8), lower flange ring (9), umbellule bar (10), gamp bar (11), control button (14), following power spring (16), handles of umbrella (17) etc. are formed, it is characterized in that at following power spring (16), umbellule bar (10) is up withstood, last power spring (7) withstands on the relevant position with lower flange ring (9), upper ramus epimere (2) and upper ramus hypomere (3) are withstood in the outer end of lower support rib (8), and skeleton opens; Upper and lower power spring (7) and (16) are compressed, the outer end of lower support rib (8) moved down interior receipts when gamp bar (11) promotion lower flange ring (9) was up mobile, and the outer end that makes upper ramus hypomere (3) upwarps interior receipts and upper ramus epimere (2) is folding, and skeleton folds automatically; Singly use power spring (7) or following power spring (16) and all can realize above-mentioned opening and closing action.

2, a kind of opening automatically as claimed in claim 1 closed the folding umbrella automatically, and when it is characterized in that umbrella stand opens, control button (14) fastens the following breach (13) of umbellule bar, and when umbrella stand folded, control button (14) fastened the last breach (12) of umbellule bar.
