Description

Umbrella opened or closed only by single hand

The utility model relates to a kind of umbrella capable of opening and closing by one hand, and it is made up of umbrella cover, umbrella frame support, umbrella frame, pole, umbrella bar and handle.

For solving user belongings, one-handed performance folding umbrella easily during on the other hand with umbrella on the other hand, the 89202528.X and 89205661.4 patent applications of Chinese patent communique bulletin provide a kind of singlehanded open-close type folded umbrella respectively.The architectural feature of these two schemes is substantially roughly the same: the umbrella bar is by outer loop bar, interior loop bar and the three shell type expansion links formed of loop bar down, hand grip control means by open and close handle, connecting rod, keying is tried to stop people from fighting each other and fixedly the rear end frame forms, can one-hand control shake hands the drivening rod knee-action to reach the purpose that opens and closes umbrella.This singlehanded open-close type umbrella, more, the complex structure of member, and also one-handed performance is also required great effort.

The utility model purpose is: overcome the deficiency of prior art, a kind of simple in structure, easy to operate umbrella capable of opening and closing by one hand is provided.

The utility model is achieved in that same as the prior art, also form by umbrella cover, umbrella frame support, umbrella frame, pole, umbrella bar and handle, different is: described umbrella bar is made of sleeve pipe and slide bar two parts, slide bar is contained in the sleeve pipe, the two displacement to axial, top end of sliding rod and umbrella frame support are connected as a single entity, and cannula tip links to each other with an end of each pole; Described handle is reached the parachute-opening handle formation that connects into " L " shape in the slide bar bottom with slide bar by overcoat, overcoat and sleeve bottom are fixedly linked, slide bar bottom and parachute-opening handle place within the overcoat and relatively overcoat along slide bar axial displacement, at parachute-opening handle upper edge sliding pole axis to having a groove, its built-in spring, the spring bottom is against on the outer casing inner wall, the top is against on the parachute-opening handle, on the parachute-opening handle, also axially drive a deep trouth along himself, this groove depth place adorns a spring, near adorning a lock pin in the outer casing inner wall place, but with also open the groove that a Rong Suosuo enters on the overcoat wall of this lock pin correspondence position, adorn a button in the groove.In the utility model, pole and umbrella frame indirection point to the distance of umbrella frame support equals the range that slide bar moves with respect to sleeve pipe.

Operation principle of the present utility model is that action control slide bar is done small distance relative to sleeve pipe and moved in the scope by a small margin that can reach with the one hand palm, to reach full opening and closing umbrella purpose.Transformation relation according to each limit of triangle that constitutes by pole, umbrella frame and slide bar in the opening and closing umbrella process.As can be known, from pole and umbrella frame mutually contact just be equal to the range of slide bar folding basically to this segment distance of umbrella frame support.Since and the utility model has been limited in the slide bar range in the singlehanded energy control scope, contact also will be more much smaller than common umbrella to umbrella frame support distance certainly.

Accompanying drawing is the utility model structural representation.

Below in conjunction with accompanying drawing the utility model embodiment is done an explanation:

As shown in the figure, the utility model is formed by being connected rivet 13, parachute-opening handle 14 and compression spring 16 thereof, pole and sleeve pipe Connection Block 15 between umbrella frame 1, sleeve pipe 2, slide bar 3, handle jacket 4, button 5, lock pin 6 and compression spring 7 thereof, umbrella top nut 8, umbrella frame pole 9, umbrella cover 10, umbrella handle adapter sleeve 11, umbrella frame support 12, pole and umbrella frame.Be illustrated as the umbrella full-gear, this moment, spring 16 was stressed, and 7 on spring is loosening, and lock pin 6 parts enter in the handle jacket 4, a part is stranded in and makes open umbrella be in self-locking state in the umbrella handle 14, and the part of button 5 is exposed at outside the handle by lock pin 6 tops.When closing umbrella, press the button 5, make it to promote lock pin 6 returns with thumb, slide bar 3 just breaks away from self-locking state like this, so under spring 16 effects, with respect to sleeve pipe 2 distance that moves up, whole umbrella is just closed fully simultaneously for parachute-opening handle 14 and the slide bar 3 that is connected as a single entity with it; Again during parachute-opening, prop up handle jacket 4, four with palm and refer to that holding parachute-opening handle 14 holds to pressing down, so slide bar 3 and parachute-opening handle 14 just will overcome the active force of spring 16 and move down, just be equivalent to move on the sleeve pipe 2 relative slide bars 3 this moment, each pole 9 of its top connection just will make umbrella be tending towards opening, when parachute-opening handle 14 moves down when putting in place, its lock pin 6 will enter under spring 7 effect in handle jacket 4 bodies automatically finishing self-locking action, and this moment, umbrella just was full-gear.In this example, the relative displacement maximum range is 20mm between design slide bar 3 and the sleeve pipe 2, size in view of the above, and pole and umbrella frame tie point 13 and umbrella frame support 12 spacings also are 20mm certainly.This will shorten many than common umbrella.Consider that 12,13 liang of pivot distances shorten, under the blast effect, these 2 and whole umbrella frame are stressed bigger than common umbrella, so need suitably to strengthen the umbrella frame size or select the high strength quality material for use.

The utility model advantage is: simple and reasonable for structure, easy to operate, laborsaving.
