Abstract

The utility model relates to an umbrella frame structure for full supporting three-fold umbrellas, composed of five umbrella frames and corresponding components. The utility model uses a compact pin-connected design and a supporting ring for the umbrella frame is arranged between the included angle of two pin-connected points, effectively enhancing the stability and straight tension of each umbrella frame when the umbrella is opened. The umbrella fabric of the whole umbrella supports the whole surface to form a streamline appearance, and each umbrella frame can mutually draw when the umbrella is opened and closed with easy opening and closing. When the umbrella is closed, each umbrella frame can automatically close to an umbrella stem under the traction of a lower nest, and the utility model has the advantages of very convenient umbrella closing, simplified whole umbrella structure and firmness and high durability.

Description

Umbrella frame structure for full supporting three-fold umbrella

The utility model relates to a kind of umbrella rib structure of Triple folding umbrella.

The parachute kit of common in the market folding umbrella has Triple folding umbrella and two folding parachute kits.Wherein the Triple folding umbrella architectural feature shows: main bone in, the inner end is articulated in the last nest of parachute kit king-rod.Fulcra in one, the inner end articulates a sliding sleeve on the following nest of king-rod.The centre of fulcra in the outer end of interior main bone is articulated in.The outer end of interior fulcra is articulated in the centre of outer main bone.Be articulated in the centre of interior main bone and the inner end of outer main bone with a middle linking bone, constitute equidistant prismatic angle and support.Its advantage is a smooth opening and closing, but no umbrella frame supports in the middle of having umbrella cover, and it is poor to form support force, and the umbrella cover weakness is easily oozed the shaky defective that easily wrecks of rainwater and umbrella frame.The architectural feature of another kind of two folding parachute kits shows: main bone in, and the inner end is articulated in the last nest of parachute kit king-rod, and the outer end is articulated in the inner end of outer main bone.Fulcra in one, the inner end is articulated in sliding sleeve on the following nest of king-rod, the centre of main bone in the outer end is articulated in.With an extension spring, the inner end is articulated in nest in the sliding sleeve between the up-down runner, and the outer end connects the inner end that a steel wire articulates outer main bone.Its advantage is that support force is strong, and umbrella cover supports and to be streamlined, but has the folding inconvenience, must the purse up king-rod loosen extension spring and just can close umbrella, and half defective such as not attractive in appearance of turning up of umbrella cover when closing umbrella.

Order of the present utility model is to be to overcome the existing technical above-mentioned defective of umbrella rib structure, provide a kind of jail that can strengthen whole umbrella cover because of the angle that closely supports and each umbrella frame forms mutually during the folding umbrella frame, draw forward " forward the umbrella rib structure of triple folding umbrella is supported in folding entirely " of smooth folding mutually.

The utility model is finished as follows: its structure is by a king-rod, nest on, and nest once, main bone in, fulcra in, main bone in the middle of, linking bone in the middle of, an outer main bone, a hollow roof pressure circle, a umbrella frame spacing collar is formed.It is characterized in that: main bone in, its inner end is articulated in the last nest of parachute kit king-rod.Fulcra in one, its inner end is articulated on the following nest that slides over the parachute kit king-rod.The outermost end of fulcra in the outer end of interior main bone is articulated in.Main bone in the middle of one, its inner end are articulated in the upper end of contiguous interior main bone outer end.The outer end of middle main bone is articulated in the inner end of outer main bone.Linking bone in the middle of one, its inner end are articulated in the upper end of contiguous interior fulcra outer end, and its outer end is articulated in the lower end of contiguous outer main bone inner end.One hollow roof pressure circle inserts the intermediate hollow of hollow roof pressure circle with rivet, in being articulated in separately in the middle of two pivoting points of fulcra outer end, with the outer end of main bone in the jacking and the inner end of middle linking bone.One umbrella frame spacing collar, near the lower end of last nest, when drawing in to limit umbrella frame in the qualification position of main bone, main bone is crossed the king-rod displacement in preventing.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is the utility model overall structure plane.

Fig. 2 is the plan view of the utility model when umbrella frame is amounted to.

The three-dimensional view that Fig. 3 articulates for each umbrella frame.

Referring to figs. 1 through Fig. 3, the utility model comprises nest 2 on the king-rod 1,, once main bone 5, one interior fulcra 6, one middle main bones 7, one middle linking bones 8, one outer main bone 9, one hollow roof pressure circles 10 in nest 3, the one umbrella frame spacing collars 4.

Shown in Figure 3 as Fig. 1, it is characterized in that: the inner end of interior main bone 5 is articulated in nest 2, and fulcra 6 articulated the outermost end of cover 6A in the outer end was articulated in.The inner end of interior fulcra 6 is articulated in sliding sleeve on the following nest 3 of king-rod 1.On the pivot joint of the main bone 5 outer ends cover 5A, its outer end was articulated in the inner end of the pivot joint cover 9A of outer main bone 9 in the inner end of middle main bone 7 was articulated in.The inner end of middle linking bone 8 is articulated in the inner end that articulates cover 6A, and its outer end is articulated in the outer end that articulates cover 9A.

As shown in Figure 3, it is characterized in that:

In the middle of the inner end and two pivoting points of outermost end on the pivot joint of the interior fulcra 6 outer ends cover 6A, a pivoting point is set separately, being inserted in hollow roof pressure circle 10, and the rivet location of packing into.The equal diameters of the thickness of hollow roof pressure circle 10 and interior main bone 5, middle linking bone 8, hollow internal diameter is done the free gyration of respective aperture greater than rivet diameter in the middle of it around rivet with circle.Hollow roof pressure circle 10 is characterised in that: when nest 3 opens umbrella frame down when rising, and the bottom of main bone 5 outer ends in the end periphery jacking of hollow roof pressure circle 10, the top of linking bone 8 inner ends in the middle of the peripheral jacking of the other end.But the downforce of main bone 5 outer ends is with the stability of linking bone 8 in the middle of controlling in its effect mat, upwards tilting displacement of linking bone 8 in the middle of avoiding, and under the effect of the main bone 7 two ends pivoting points in centre, form angle, to pin down the stability of outer main bone 9, strengthen the straight and upright intensity that umbrella frame opens each umbrella frame of back.

As shown in Figure 2, it is characterized in that: when umbrella frame spacing collar 4 drew in umbrella frame, interior main bone 5 was limited in being parallel to the relevant position of king-rod 1, avoided umbrella frame 5 to cross king-rod 1 displacement, kept in place closing up of the order of each umbrella frame when closing umbrella.

The umbrella rib structure of triple folding umbrella is supported in this forward folding entirely, and strengthen umbrella frame effectively and supported very tension force, smooth opening and closing, umbrella cover supports comprehensively, and has simplified umbrella rib structure, and packaging technology is simple and easy, and labor and material saving reduces production costs effectively, increases economic efficiency.
