These umbrellas that technique scheme provides though all increased the function of rainproof, also exist defective, promptly can't accomplish to allow umbrella-holding human's back away from the edge of umbrella.

The utility model content

The purpose of this utility model is to overcome the prior art above shortcomings, by improvement to existing umbrella structure, provided a kind of novel eccentric umbrella, simple in structure, rainproof obvious results characteristics that this eccentric umbrella has, the umbrella cover in an original center of circle is changed into the umbrella cover in two centers of circle, the position thereby the best that makes the umbrella-holding human also be in umbrella cover is taken shelter from rain, thus accomplish to allow umbrella-holding human's back away from the edge of umbrella.

The technical scheme that the utility model provides is: this eccentric umbrella comprises umbrella cover, the umbrella bar, umbrella cover bone bar, open and close bone bar and switching mechanism, be characterized in that described umbrella shape is that two semicircles are connected and form, the center of circle of one of them semicircle is umbrella-holding human's position, the center of circle of another semicircle is umbrella bar center, the junction of these two semicircles is a rectangular shape, in the rectangle junction of two semicircles, be that the position of fillet of the semicircle in the center of circle is higher than with umbrella-holding human with the umbrella bar be the fillet of the semicircle in the center of circle, supporting with umbrella-holding human is that the umbrella cover bone bar length of the semicircle umbrella cover in the center of circle is longer than the umbrella cover bone bar that support is the semicircle umbrella cover in the center of circle with the umbrella bar.Because the center of circle of a present semicircle is changed into by the cyclotomy string center of original circular parachute in umbrella-holding human's position, cover the human body umbrella cover and increase thereby make, solved the problem that umbrella-holding human's back is not soaked with rain effectively.

In technique scheme, two semicircle radiuses of eccentric umbrella can equate, also can be unequal, and wherein semicircle radius, centre-to-centre spacing, umbrella cover bone bar length and position is selected, can determine according to the empirical data of existing umbrella maker skill.

Compared with prior art, the beneficial effects of the utility model are to have simple in structure, rainproof obvious results characteristics, the umbrella cover in an original center of circle is changed into the umbrella cover in two centers of circle, the position thereby the best that makes the umbrella-holding human also be in umbrella cover is taken shelter from rain, thus accomplish to allow umbrella-holding human's back away from the edge of umbrella.
