Abstract

The utility model relates to an automatic umbrella which can be automatically opened and closed. The utility model comprises a hinged skeleton, a telescopic strut, an automatic umbrella opening mechanism and an automatic closing mechanism for the hinged skeleton. A used only needs one hand to realize opening the umbrella so the operation is convenient.

Description

Automatic umbrella

The utility model relates to a kind of automatic umbrella, particularly a kind of can automatic deployment and close the automatic umbrella of umbrella automatically.

In the prior art, automatic umbrella is arranged, it includes by four support bones be hinged the parallelogram hinge skeleton that becomes to have three to prolong limits, telescopic strut and by the automatic parachute opener that switch constitutes that links on spring in the telescopic strut and the handle.Link switch when pressing, under the effect of spring force, telescopic strut extends automatically and the hinge skeleton is opened and is realized automatic deployment.But it can not close umbrella automatically, and the end user must with the hands close umbrella, uses some inconvenience, especially end user one portable during other things, just be difficult to close umbrella.

The automatic umbrella that the purpose of this utility model is to provide a kind of energy automatic deployment and closes umbrella automatically, it is extremely convenient to use.

For achieving the above object, the utility model adopts following technical proposals: the same hinge skeleton, telescopic strut and the automatic parachute opener of including with prior art of the utility model.It is characterized in that also being equipped with hinge skeleton automatic closing gear.In use, actuating hinge skeleton automatic closing gear just makes hinge skeleton closure, realizes closing umbrella.The structure of described hinge skeleton automatic closing gear can be designed as: an extension spring is installed between lower supporting bone outer end in the hinge skeleton and the upper supporting bone middle and lower part; A stay cord is arranged in telescopic strut, and the one end is drawn from the telescopic strut upper end and is to be connected on the lower support ring of hinge skeleton, and other end system is connected on the binding post; Switch on binding post lower end and the handle links mechanism and interlock, and telescopic strut inner chamber top has a hollow push pipe overlapping stay cord and aiming at binding post.During parachute-opening, under the effect of stay cord pulling force, the hinge skeleton is opened; When console switch links mechanism binding post is threaded off, remove the pulling force of stay cord, then be hinged skeleton under the effect of extension spring and auto-closing realizes closing umbrella; Exert pressure telescopic strut shunk in last umbrella top, automatic parachute opener snap close then, and binding post is under the roof pressure of hollow push pipe and linked mechanism's snap close by switch.The structure that above-mentioned switch links mechanism can be designed as: an end conflict automatic parachute opener of a Sidesway switch link switch, and the fork top of a Y-piece of other end conflict, the recess of Y-piece and binding post lower recess link, and the Y-piece bottom surface has little spring to support.Press Sidesway switch and touch Y-piece, thereby binding post and Y-piece are threaded off, remove the backguy pulling force and realize closing umbrella.When exerting pressure and telescopic strut shunk in the umbrella top, the downward roof pressure binding post of hollow push pipe in it, then the binding post lower recess falls into the Y-piece recess and is linked, and waits for next time and closes the umbrella operation.

The utility model has following conspicuous advantage compared with prior art: the utility model not only can automatic deployment, and can close umbrella automatically, and the end user only need realize umbrella with a hand, and is easy to use.

The drawing explanation of accompanying drawing:

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is the vertical view of Y-piece.

An optimum implementation of the present utility model is: referring to accompanying drawing, this automatic umbrella includes by four support bones be hinged the parallelogram hinge skeleton 1 that becomes to have three to prolong limits, telescopic strut 10 and by the automatic parachute opener that switch 12 constitutes that links on spring 8 in the telescopic strut 10 and the handle 18.The upper supporting bone 4 of hinge skeleton 1 is hinged with the upper support ring that is fixed in telescopic strut 10 upper ends 6, and its lower supporting bone 3 is hinged with the lower support ring 5 that slides on the telescopic strut 10.A hinge skeleton automatic closing gear also is housed.The structure of hinge skeleton automatic closing gear is: an extension spring 2 is installed between lower supporting bone 3 outer ends in hinge skeleton 1 and upper supporting bone 4 middle and lower parts; A stay cord 7 is arranged in telescopic strut 10, and the one end is drawn from telescopic strut 10 upper ends and is to be connected on the lower support ring 5 of hinge skeleton 1, and other end system is connected on the binding post 13; Switch on binding post 13 lower ends and the handle 18 links mechanism 15 and interlock, and telescopic strut 10 inner chamber tops have a hollow push pipe 9 overlapping stay cord 7 and aim at binding post 13.The structure that switch links mechanism 15 is: an end conflict automatic parachute opener of a Sidesway switch 14 link switch 12, this protruding hook that links below switch 12 upper ends can link with opening 11 couplings on the last loop bar of telescopic strut 10, and the fork top of a Y-piece 16 of the other end of Sidesway switch 14 conflict, the recess of Y-piece 16 and binding post 13 lower recess link, and Y-piece 16 bottom surfaces have little spring 17 to support.

Claims

1. automatic umbrella comprises hinge skeleton (1), telescopic strut (10) and automatic parachute opener, it is characterized in that also being equipped with hinge skeleton automatic closing gear.

2. automatic umbrella according to claim 1, the structure of the skeleton automatic closing gear that it is characterized in that being hinged is: an extension spring (2) is installed between lower supporting bone (3) outer end in hinge skeleton (1) and upper supporting bone (4) middle and lower part; A stay cord (7) is arranged in telescopic strut (10), and the one end is drawn from telescopic strut (10) upper end and is to be connected on the lower support ring (5) of hinge skeleton (1), and other end system is connected on the binding post (13); The mechanism (15) that links on binding post (13) lower end and handle (18) switch interlock, and telescopic strut (10) inner chamber top has a hollow push pipe (9) overlapping stay cord (7) and aims at binding post (13).

3. automatic umbrella according to claim 2, it is characterized in that the structure that switch links mechanism (15) is: an end conflict automatic parachute opener of a Sidesway switch (14) link switch (12), and the fork top of an other end Y-piece of conflict (16), the recess of Y-piece (16) and binding post (13) lower recess link, and Y-piece (16) bottom surface has little spring (17) to support.
