Abstract

The utility model relates to a flexible umbrella frame bent angle structure of a multi-fold umbrella; primarily, a bent angle structure 12 is arranged at the outer side end of the flexible umbrella frame in an umbrella frame group; when opened, the umbrella which becomes flat is butted by a second umbrella frame 3; simultaneously, elastic energy is stored. When the umbrella is closed, the umbrella frame is conveniently folded under the action of the reverting elastic force.

Description

The flexible bone bending angle of a kind of many folding umbrellas structure

The utility model relates to the parachute kit class, the flexible bone bending angle of particularly a kind of many folding umbrellas structure.

As everyone knows, structure for many foldings umbrella, usually exist and each umbrella frame is presented after the parachute-opening to be almost parallel state, therefore when closing one's umbrella, because application of force angle problem, making the umbrella frame frame be difficult for being recovered as easily the situation of folding umbrella, is common improvement design as shown in Figure 1, mainly is that the medial extremity at flexible bone 1 is provided with a kink 11, it is the outer end position that is positioned at first umbrella frame 2, after parachute-opening, be butted on the upside of first umbrella frame 2, and when closing one's umbrella, utilize its back stretch with first umbrella frame 2 to pressing down, with the enforcement that facility closes one's umbrella, this design really can provide a power-assisted that closes one's umbrella, but also quite limited, because of the moment that its point of application produced few, so its downward elastic force is also little relatively, be further improved, be a shortcoming in fact.

The purpose of this utility model is exactly to be difficult for reclaiming shortcoming at the umbrella frame frame that above-mentioned many folding umbrellas exist, and the flexible bone bending angle of a kind of many folding umbrellas structure is provided, and makes it when closing one's umbrella, and under the effect of back stretch, helps the recovery action of umbrella frame frame.

Technical conceive of the present utility model:

According to the purpose of this utility model, the flexible bone bending angle of a kind of many folding umbrellas structure is provided, mainly be to establish bending angle structure with wide-angle at the outboard end of flexible bone, make it when parachute-opening, flattened by replacing of second umbrella frame, and have enough recovery elastic force, when closing one's umbrella, under the effect of this back stretch, help the recovery action of umbrella frame frame.

Accompanying drawings structure of the present utility model and embodiment:

Fig. 1 is the structural representation of common umbrella frame frame.

Structural representation when Fig. 2 is umbrella frame frame parachute-opening of the present utility model.

Structural representation when Fig. 3 closes one's umbrella for umbrella frame frame of the present utility model.

1 is that flexible bone, 11 is that kink, 12 is that bending angle structure, 2 is that first umbrella frame, 3 is that second umbrella frame, 4 is that the first secondary umbrella frame, 5 is the umbrella coccyx.

Shown in accompanying drawing 2 and accompanying drawing 3, flexible bone 1 of the present utility model mainly is the bending angle structure 12 that is provided with a wide-angle at its outboard end, and tail end is articulated in the inner of umbrella coccyx 5, and first umbrella frame 2 is then passed in the inner of flexible bone 11, and is incorporated into the nearly outer end position of the first secondary umbrella frame 4; When parachute-opening, flexible bone 1 is subjected to replacing of second umbrella frame 3, and make its bending angle structure 12 almost be bordering on parallel position, be to have stored a large amount of back stretch, when when closing one's umbrella, this elastic force can provide and press down second umbrella frame 3 and spur the first secondary umbrella frame 4, under the running, becomes very light and smooth and can make to close one's umbrella to move in these 2 active forces.

The utility model is simple in structure, easy to make, can improve the energy that stores back stretch, and cooperates under the relative change of executing to point, helps the recovery action of parachute kit.

Claims

1. roll over the flexible bone bending angle of umbrella structure one kind more, it is that outer end with flexible bone (1) is articulated in umbrella coccyx (5), and first umbrella frame (2) is run through in the inner and be incorporated on the first secondary umbrella frame (4), it is characterized in that being provided with in the outer end of flexible bone the bending angle structure (12) of a wide-angle.
