Abstract

The utility model discloses a multiple layer folding umbrella improved closing structure, comprising an umbrella frame set for a usual parallel four-connecting-rod mechanism and an umbrella central bar. The utility model is characterized in that the inner side of a second branch frame is provided with a concave part where a convex point on the outer end of a first main frame can be inserted in when the umbrella is closed, enabling the volume of the umbrella after closing to be smaller. The outer end of the second branch frame is arranged to a bent oblique part with an oblique degree, and the umbrella can be conveniently closed with labor saving.

Description

Multiple layer folding umbrella improved closing structure

The utility model relates to a kind of folding umbrella bone structure, and particularly multiple folding umbrella bone folds structure-improved.

Multiple different folding umbrella is arranged at present, has similar umbrella frame group structure, be and utilize parallel four-bar linkage to make it the purpose that reaches parachute-opening and close one's umbrella, its umbrella frame design mainly is the umbrella frame that utilizes the U-shaped cross section, hold less umbrella frame, make the volume after closing one's umbrella less, yet the shape of various existing umbrella frames is straight strip, therefore form salient point easily at the hinged end points of umbrella frame, resistance mutually when causing closing one's umbrella has hindered further to reduce volume, and has opened when closing one's umbrella, because of the factor of the angle and the application of force, comparatively require great effort.

The purpose of this utility model is to provide a kind of multiple folding umbrella bone to fold structure-improved, can reduce volume when closing one's umbrella, and open when closing one's umbrella, can be because of the component effect, and it is free and relaxed that the operator is used.

The purpose of this utility model is achieved in that it comprises rod in the umbrella frame group of the parallel four-bar linkage that has usually and the umbrella, it is characterized in that being provided with a depressed part in the inboard of second fulcra, when closing one's umbrella, can embed in it for the outer end salient point of the first main bone, make when closing one's umbrella volume littler, and the outer end of second fulcra is designed to crooked tiltedly portion, can conveniently close one's umbrella and laborsaving.

About the gradient of the crooked tiltedly portion of the second fulcra outer end is with 45 degree is good.

Below in conjunction with drawings and Examples the utility model being done one elaborates:

Description of drawings:

Fig. 1 is the plane of the utility model umbrella frame group standard-sized sheet;

Fig. 2 is the half-open plane of the utility model umbrella frame group;

Fig. 3 is the plane that the utility model umbrella frame group closes one's umbrella.

As shown in drawings, the utility model has used the prior art about rod in umbrella frame group and the umbrella, wherein the inner of the first main bone (1) is hinged on the upper end of rod (3) in the umbrella, position between outer end (42) then is hinged among the second main bone (11), the inner of the second main bone (11) is connected in and can goes up on the movable nest (31) of slippage by rod (3) in umbrella, its outer end is hinged with the inners of the 3rd main bone (12) and second fulcra (2) respectively, and the crooked tiltedly portion (22) in the outer end of second fulcra (2) is hinged with the 4th main bone (13); First fulcra (44) the inner is incorporated into the outer section of the first main bone (1), and its outer end (40) are articulated in the inner of the 3rd main bone (12).Present embodiment is characterised in that the inboard of second fulcra (2) is provided with a depressed part (21), and its outer end is made as crooked tiltedly portion (22), and the crooked tiltedly gradient of portion (22) is 45 degree.

In sum, the utility model has the advantage of: owing to be provided with depressed part (21) at second fulcra (2), the protrusion that end forms outside the first main bone (1) partly just is involutory, so that coming closer of can trying one's best of umbrella frame group, can effectively reduce volume, when wanting parachute-opening, as shown in Figure 3, because the crooked tiltedly existence of section (22), so in the application of force with movable nest (31) when upwards pushing away, the power of this vertical direction can be changed into oblique component, and the umbrella frame group is opened outward, reaches the labour-saving purpose.

Claims

1, a kind of multiple folding umbrella bone folds structure-improved, and it comprises rod in the umbrella frame group of parallel four-bar linkage and the umbrella, it is characterized in that: be provided with a depressed part (21) in the inboard of second fulcra (2), and its outer end is made as crooked oblique portion (22).

2, multiple folding umbrella bone according to claim 1 folds structure-improved, it is characterized in that: the crooked tiltedly gradient of portion (22) of second fulcra (2) outer end is made as about 45 degree to good.
