The specific embodiment

Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.

The present invention both can be applicable to vertical frame umbrella, also can be applied to multi-fold umbrella.

Take vertical frame umbrella as example, as shown in Figure 3, the present invention opens and receives smoothly that automatic umbrella frame comprises: umbrella shaft 1, upper nest 2, middle nest 31, lower nest 32, main bone 8, support rib 5 pull bars 6 and deployment spring 7.Wherein, described upper nest 2 is fixed on umbrella shaft 1 top, and described middle nest 31 is slidingly socketed on umbrella shaft 1 with lower nest 32 and is fixedly connected with between the two, and the distance between middle nest 31 and the lower nest 32 is fixed thus.Described main bone 8 is used for supporting umbrella cover, and its inner and upper nest 2 articulates.Described support rib 5 inner and middle nests 31 articulate, and the outer end then is articulated in described main bone 8 middle parts.Described pull bar 6 inner and lower nests 32 articulate, and the outer end is connected in support rib 5 middle parts.

As shown in Figure 6, this special feature is: described pull bar 6 outer ends connect described support rib 5 by a collar 61, this collar 61 is slidingly socketed on described support rib 5, and described deployment spring 7 is enclosed within outside the described support rib 5 and is folded between the described collar 61 and the middle nest 31.Because the distance between middle nest 31 and the lower nest 32 is fixed, to open when closing one's umbrella, the angle between pull bar 6 and the support rib 5 will change, and the tie point of pull bar 6 and support rib 5, also is the also correspondingly inside and outside variation of sliding of position of the collar 61.When closing one's umbrella, as shown in Figure 5, the described collar 61 of described pull bar 6 tractives inwards direction slides and compresses described deployment spring 7 and makes it storage elasticity potential energy; During parachute-opening, such as Fig. 6, the elastic potential energy of described deployment spring 7 discharges, thereby namely its elastic potential energy outwards promotes the described collar 61 by sliping off umbrella on the described lower nest 32 of pull bar 6 pullings.Because deployment spring 7 is enclosed within on the support rib 5, therefore can not produce the accident that springback is hurted sb.'s feelings, fool proof in the use, deployment spring 7 produces the correcting effect to it when the collar 61 inside and outside the slip in addition, frictional force between the collar 61 and the support rib 5 is reduced greatly, therefore, open to close one's umbrella and feel very smooth and easy.

Can adopt multiple connected mode between described pull bar 6 and the collar 61.As shown in Figure 4, in one embodiment, the described collar 61 bottoms are installed with a grab 62, and described pull bar 6 can adopt steel wire and its outer end and described grab 62 hook joints.Adopt the mode of this clasp joint, assemble very convenient quick.

As shown in Figure 3, in order to prevent that described middle nest 31 and lower nest 32 are excessively upper sliding, make whole umbrella frame more firm, be fixedly installed backstopping assembly 21 between nest 2 and the middle nest 31 on described on the described umbrella shaft 1, this backstopping assembly 21 can be the sleeve along described upper nest 2 bottom surfaces to downward-extension, also can be to be convexly set in salient point on the umbrella shaft 1, bulge loop etc., so long as the position that radially protrudes from outside middle nest 31 internal diameters gets final product.

As shown in Figure 4, the inner of described support rib 5 is installed with the diameter joint 51 large than its middle part, can better described deployment spring 7 be folded between this joint 51 and the described collar 61, prevents that deployment spring 7 the inners from offseting with middle nest 31.

The present invention opens and receives smoothly that automatic umbrella frame can also be applied to multi-fold umbrella, take two folding umbrellas as example, as shown in Figure 7, the structure of its automatic deployment is identical with vertical frame umbrella, do not repeat them here, the main bone 8 that just is used for the support umbrella cover is comprised of facial bone 81 and coccyx 83, and this facial bone 81 links to each other by backguy 82 with coccyx 83.For the umbrella of different broken numbers, described main bone 8, support rib 5 etc. can also have other type of attachment, but the structure of its automatic deployment all is identical.

The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
