Description

Multi-folding all-weather umbrella

The utility model is a kind of many folding en-toutcas.

For these years, easy to carry in order to make umbrella, people have carried out multiple transformation to it, have at first made the eighty percent discount umbrella, have produced triple folding umbrella afterwards again, do one with regard to prior art below and simply discuss.

1. the automatic umbrella of eighty percent discount: owing to adopted eighty percent discount formula umbrella frame, and automatic parachute opener has been installed, has been made umbrella to open automatically, used easily, but because umbrella frame can only be rolled over eighty percent discount, like this, after umbrella draws in, length still seem grown a little.

2. three roll over en-toutcas: in order to overcome the length issue after the eighty percent discount umbrella draws in, people have developed triple folding umbrella then, but the being seen triple folding umbrella of existing market, because the 3rd folding only is to rely on a pin joint to connect with second folding of umbrella frame, when opening, umbrella is easy to turn over, therefore needing earlier to put in order with hand could smooth opening, and this has just brought inconvenience to use.

The utility model has provided a kind of new-type en-toutcas, and its umbrella frame can be made into three foldings, four foldings or multi-fold structure such as five foldings, and also opening ways can make automatic or non-automatic formula as required, shows to be described as follows with regard to its principle:

This en-toutcas is by folding umbrella rib＜1 〉, umbrella cover＜2 〉, telescopic umbrella bar compositions such as＜3 〉.With the automatic umbrella of three foldings is example, see figure one, wherein folding umbrella rib is to be that elementary cell constitutes by the leverage shown in figure two, this leverage be by two bars in the middle part hinged forming, two bars can relatively rotate around pin joint, and are as required that several this leverages are mutually hinged.See figure three, like this when two bars of any one leverage wherein when the pin joint of himself rotates mutually, two bars that just can drive other leverage rotate mutually around pin joint separately, finish whole opening with this, close, this folded umbrella is made according to this principle.

For from inside to outside downward-sloping is arranged after umbrella cover is opened, so that rainwater flows down, can be variant slightly with making length near two bars of the leverage of umbrella bar one end, in addition, in the end of the umbrella frame other end of umbrella bar (promptly with respect to) leverage, wherein one is quarter butt, it is hinged that its end points and stock are tee T, sees figure four, like this, after the whole connection of umbrella frame, make that umbrella cover was close on the stock of this leverage when umbrella was opened, see figure one, (wherein A is a stock) so just can make three foldings as required, four foldings, many folding umbrella frames such as five foldings.

The umbrella bar can be made telescopic or non-automatic telescopic automatically according to different needs, and two joints are telescopic same as the prior art automatically.Three joints are above telescopic automatically in each joint (removing a terminal joint) of umbrella bar spring being set all, other structure is identical with the general automatic umbrella umbrella of eighty percent discount bar, with three joints is that example is seen figure five, non-automatic telescopic umbrella bar is identical with existing common triple folding umbrella umbrella bar, all there is not spring in each joint, and can make three joints as required, four joints, five joints etc.

In sum, the utility model is a kind of novel many foldings en-toutcas, and it had both satisfied this requirement easy to carry, uses also easily, and simple in structure, makes easily.

Most preferred embodiment:

The automatic en-toutcas of＜one〉three folding: the bar length of intersection leverage is 17 centimetres, and umbrella is three folded structures, and the umbrella bar is three joint self-actions, and after umbrella was opened, diameter was not less than 90 centimetres, draws the back total length in less than 25 centimetres.

＜two〉four folding en-toutcas: the bar length of intersection leverage is 13 centimetres, and umbrella is four folded structures, and the umbrella bar is four joints, and umbrella is opened the back diameter and is not less than 90 centimetres, draws the back total length in less than 18 centimetres.
