Abstract

The utility model discloses a folding umbrella with a retractable umbrella surface, wherein a slide seat is provided on a rod, the slide seat is pivotally connected to a driving bone, a folding umbrella rib is pivotally connected between the driving bone and the top end of a middle rod, and the folding umbrella rib is provided with a first section of folding structure, the first section of the folding structure is composed of a fixed bone and a movable bone, and the two can be relatively retracted, wherein one end of the movable bone is pivotally connected to the top end of the middle rod, and the fixed bone is pivotally connected to the driving bone, thereby forming a telescopic connecting rod structure, so that the utility model can greatly increase its rain-shielding area when unfolded, and can reduce the volume when folded for easy storage.

Description

A kind of folding umbrella of scalable umbrella cover

The utility model relates to the parachute kit field, refers to a kind of folding umbrella of scalable umbrella cover especially.

At present, common umbrella can roughly be divided into the folding umbrella according to its structure, wind resistance umbrella etc., every kind of structural form has its unique function according to its use occasion and purposes, for adapting to big multi-user's actual demand, with regard to the design of folding umbrella part, can be two folding umbrella or triple folding umbrellas, to reach when not using, but its folding structure can make things convenient for the user to put with oneself, this folding umbrella is adopted by the Ms quite, because the volume of this folding umbrella after folding is enough to be placed in the suitcase, yet, to hide the rain area proportional for fold volume and the umbrella cover of this folding umbrella, cause this folding umbrella mostly must sacrifice condescend to take this post small size after folding of big screening rain area, thus, when the user in use, if the force of rain is big slightly, user's trouser legs very easily are subjected to the invasion and attack of rainwater.

The purpose of this utility model promptly will provide a kind of folding umbrella of scalable umbrella cover, and its first section folding structure can significantly increase it upon deployment and hide the rain area, and can reduce its total length relatively and be convenient to collection when folding.

For reaching above-mentioned purpose, solution of the present utility model is: a kind of folding umbrella of scalable umbrella cover, be provided with first section folding structure between Bang top and the driving bone therein, this first section folding structure is made up of bone fixation and movable bone, and the bottom pivot that drives bone one end and bone fixation connects, the top of rod during movable bone one end pivot is connected in, its other end and bone fixation are involutory mutually.

In addition, the Jiong shape section of said fixing bone is greater than the section of movable bone, and the bottom of bone fixation is extended with pivot and wears the ear of pulling, and can be provided with the arc guide face at the free end of movable bone, intermediary's bone is pivoted in the end of movable bone photo centering rod, the other end of this intermediary's bone articulates with driving bone, can be set as a telescopic wrinkled surface at the top of middle rod, the umbrella cover that drives on bone and the movable bone simultaneously.

After adopting said structure, first section folding structure of the present utility model its total length that when launch hiding rain, can outwards increase smoothly, stretch at interlock umbrella cover fold place simultaneously, makes the utility model reach the effect that small size collection and large tracts of land hide rain at its screening area of the rainy amplification of minimum folding volume.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Fig. 1 is the position view of the utility model dependency structure;

Fig. 2 is a umbrella frame decomposing schematic representation of the present utility model;

Fig. 3 is a umbrella frame combination schematic diagram of the present utility model;

Fig. 4 is that umbrella frame of the present utility model folds schematic diagram;

Fig. 5 is that umbrella frame of the present utility model launches schematic diagram.

At first see also shown in Fig. 1-3, be slidingly equipped with slide 20 on the rod 10 in of the present utility model, five equilibrium is pivoted with and drives bone 30 around the slide 20, drive bone 30 positions relatively is pivoted with and folds umbrella frame 1 (folding the broken number of umbrella frame 1 and dependency structure not in restriction of the present utility model, so do not add detailed description) on middle excellent 10 top.First section folding structure that the utility model folds umbrella frame 1 is located between the top and driving bone 30 of middle rod 10, and this first section folding structure is made up of bone fixation 41 and movable bone 42, wherein:

Drive bone 30 1 end position places relatively wears pivot a part 43 is arranged in the bottom of bone fixation 41, the top of rod 10 during one end pivot of movable bone 42 is connected in, the other end is then involutory with bone fixation 41, now specify: the door shape section of bone fixation 41 is greater than movable bone 42, make movable bone 42 can follow the standard of bone fixation 41 and flexible slippage, stretch for making movable bone 42 can in bone fixation 41, stablize slippage, the utility model can extend ear 411 near movable bone 42 ora terminalis bottom in bone fixation 41, the combination of pulling can be worn by pivot 412 by this ear 411, make movable bone 42 bottoms be subjected to the restriction of pivot 412, and successfully flexiblely and unlikely in bone fixation 41 deviate from, and the free end at movable bone 42 is provided with arc guide face 421, this arc guide face 421 can make movable bone 42 successfully flexible between pivot 412 and axle part 43, again, the end of this activity bone 42 rod 10 in relatively is pivoted with intermediary's bone 50, the other end of this intermediary's bone 50 then is articulated in the appropriate position that drives bone 30, constitutes by bone fixation 41, movable bone 42, middle rod 10, drive the shrinking connecting-rod structure that bone 30 and intermediary's bone 50 are formed.

When the utility model folds, as shown in Figure 4, it drives bone 30 can be involutory towards middle excellent direction, at this moment, this driving bone 30 can be pushed bone fixation 41 to movable bone 42 directions, the utility model makes activity bone 42 be contracted in the bone fixation 41, makes first segment length reduction that folds umbrella frame 1, even can smaller volume be carried or collect for the user.

When the utility model launches, as shown in Figure 5, driving bone 30 can be with bone fixation 41 extrapolation, make movable bone 42 by stretching out in the bone fixation 41, the total length of first section folding structure is significantly increased, and will be arranged in the top of the utility model rod 10, the umbrella cover that drives on bone 30 and the movable bone 41 is set as a telescopic wrinkled surface, this wrinkled surface can be expanded with the increase of first section folding structure length, makes the user more not be vulnerable to the invasion and attack of rainwater.
