Abstract

The utility model discloses a cover-adjustable pavilion roof type umbrella. The cover-adjustable pavilion roof type umbrella is characterized in that both sides of the upper part of an umbrella bar (3) are provided with an elongated slot (20). The upper part of the umbrella bar provided with the elongated slot is provided with an upper plate (15). The lower part of the upper plate is provided with a movable buffering spacing pipe (14). The upper part of the upper plate is provided with a movable sleeve pipe plate (16). The hollow part of the umbrella bar milled with the elongated slot (20) is provided with an adjusting push rod (18) with an adjusting bead (19). One end of the push rod which is fixed with the movable buffering spacing pipe (14) with a pin (13) can move in the elongated slot (20) from top to bottom. The length of the umbrella slice cloth which is used for forming an umbrella cover (12) of the umbrella is longer than an umbrella frame with the same specification. Therefore, when the umbrella is opened and is expanded, because the central plate (7) of an automatic switching-on umbrella or the lower plate (5) of a hand open type umbrella is pushed upwards, with the function of the elongated slot (20) and the push rod (18), the shape of the umbrella is straight and is like a pavilion roof. The expansion and contraction of the umbrella cover can be adjusted. The speed of rain water which flows is accelerated. The cover-adjustable pavilion roof type umbrella is beautiful, elegant, convenient and practical.

Description

Cover-adjustable umbrella

The utility model relates to the improvement invention of self opening or manual open-type en-toutcas.

Hand open type of supplying on the market in the prior art, or the en-toutcas of opening automatically, mainly form by umbrella handle, umbrella bar, umbrella top, umbrella frame and umbrella cover etc., after the new cloth cut-parts of the umbrella cover of this umbrella, owing to be subjected to the influence of umbrella cloth quality and weather humidity, the umbrella cover expansion and contraction differs greatly, tend to produce shrinkage factor when big parachute-opening ineffective, when the extension rate is big, the loose crape top phenomenon of umbrella cover even the return of goods of doing over again situation is arranged.Look into Chinese patent, (CN033203U) the weatherproof umbrella of Ye Hongchun design, he on the en-toutcas of self opening or hand open type " synthetism that is attempted by the long bone lower end greatly than long bone elasticity places above the dish and is enclosed within spring and assembly cap on the umbrella bar, piece become umbrella cover sheet its open the door to cut out more smallerly than same specification ".Like this when strutting umbrella cover, synthetism is with regard to the pressure that is subjected to umbrella cover and be bent downwardly naturally.Thereby just increased the resupinate wind loading rating of umbrella cover, and be enclosed within on the umbrella bar putting a top spring on last the coiling, when umbrella cover strutted, under the effect of top spring, the core of umbrella cover will become a tall and straight peak like this, umbrella shape so not only attractive in appearance, and reduced the pressure of wind, and strengthen the rainwater speed of trickling downwards, but this structure has its deficiency, because the top spring still makes umbrella sheet drawing down in acting when umbrella does not use, the ineffective or crape top phenomenon of parachute-opening often appears.

In view of the deficiency of known technology, the en-toutcas that the purpose of this utility model is intended to self opening or hand open type is not subjected to climate change, and the umbrella cover cloth is flexible unrestricted, and umbrella cover can be regulated and strut back umbrella cover Cheng Tingding shape, and is attractive in appearance full.Convenient and practical.

The utility model is finished as follows.Above the umbrella bar of former self opening or hand open type en-toutcas, be milled with two elongated slots symmetrically, last dish is enclosed within on the umbrella bar that is milled with the elongated slot top, movable buffer limit pipe is equipped with in last dish below, the top is with the moving casing dish, and have in the umbrella bar hollow part that is milled with elongated slot adjusting push rod that a band regulates pearl with pin with can in elongated slot, move up and down after movable buffer limit pipe is fixedlyed connected.

When unfurling an umbrella, because the adjusting push rod is followed movable buffer limit pipe and moved up in the elongated slot of umbrella bar both sides, because the piece umbrella cloth is slightly longer than the umbrella stand of same specification,, umbrella cover and moving casing dish move up again so also following adjusting rod, after umbrella all strutted, just become booth top shape en-toutcas.When closing one's umbrella, the adjusting push rod is followed movable buffer limit pipe and is moved down in the elongated slot of umbrella bar, and promptly closing one's umbrella finishes.

The utility model has following accompanying drawing
