CN2070116U - Adjustable long handle umbrella with automatic open and close functions - Google Patents

Abstract

The utility model relates to an automatic umbrella, which comprises an umbrella frame, an inner supporting rod, an outer supporting rod, a core rod and a handle. The lower portion of the core rod is provided with a spring and a stroke adjusting step, a bit of displacement of the core rod in a handle is utilized to cause an included angle between the inner supporting rod and the outer supporting rod to be spread, and the umbrella is opened. Meanwhile, a spring is compressed, and the spring is returned to automatically cause the umbrella to be closed. The automatic umbrella automatically opens and closes, and the spread extent can be adjusted. The automatic umbrella has simple structure and low cost.

Description

But from opening from falling the amplitude modulation long umbrella

The utility model relates to a kind of en-toutcas, particularly a kind of automatic en-toutcas.

Present en-toutcas, no matter be folded umbrella or long umbrella, it is semi-automatic that its automatic degree all can only reach, and promptly opens automatically, and can not receive automatically, bring inconvenience to people, especially carry under the situation such as other article getting on the bus, embrace child or hand, its shortcoming is more outstanding, in addition, it is non-adjustable that this class umbrella opens amplitude, and the amplitude of opening of wanting to dwindle umbrella under the less occasion in space is just very inconvenient.

The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, to open certainly from falling the amplitude modulation long umbrella but provide a kind of.

The utility model is by umbrella frame, internal overarm support, outer strut, core bar and handgrip are formed, the external end head that is characterized in some internal overarm supports is corresponding hinged with the upper end of the outer strut of identical radical respectively, the together corresponding respectively simultaneously top that is hinged on the umbrella frame of identical radical, the inner termination and the pin head of some groove internal overarm supports are hinged, and the some mutual angle α of internal overarm support spend less than 180, the structure of pin head is identical with the umbrella header structure of existing umbrella, it is fixed on the upper end of core bar, the upper end and the umbrella crown of some umbrella frames are hinged, be empty between umbrella crown and the pin head, the lower end of some outer struts and core retainer plate head are hinged, the core retainer plate head also umbrella header structure with existing umbrella is identical, there is a through hole at its center, core bar passes this through hole, the core retainer plate head is fixed on the top of core retainer plate, core retainer plate is the cylinder type hollow pipe, its length is less than the length of core bar, it is enclosed within on the core bar, fixedly connected with spring overcoat in its lower end, spring overcoat is a sleeve pipe, the internal diameter of spring overcoat and the external diameter of core retainer plate match, their junction forms a step, fixedly connected with the upper surface of handgrip in the lower end of spring overcoat, be positioned on the core bar of spring overcoat and be with spring, the upper end of spring withstands on the step surface of spring overcoat and core retainer plate junction, the lower end of spring is pressed on the stroke adjustment step of core bar bottom, core bar is a solid straight-bar, from the last core retainer plate head that passes successively, behind core retainer plate and the spring overcoat, its underpart is positioned at handgrip, the core bar bottom that is positioned at handgrip is provided with some stroke adjustment steps, be used to regulate the opening angle of umbrella frame, the stroke adjustment step is thin circular face, each stroke adjustment step is at a distance of certain intervals, there is an outwardly directed handle vertical with core bar the core bar lower end, this handle passes in vertical elongated slot of handgrip side, handgrip is a hollow-core construction, its side has vertical elongated slot, on its upper surface switch is housed, switch is a brace, jib head is pressed head, there is a pointed dop brace lower end, be used for cooperating with the stroke adjustment step, the centre of switch brace is hinged by the upper surface of latch and handgrip, be connected with the one side of leaf spring simultaneously in the middle of the switch brace, the another side of leaf spring is close to the spring overcoat outer surface.

Below in conjunction with its course of action of description of drawings.

Fig. 1 is the utility model deployed condition schematic diagram;

Fig. 2 is the utility model collapsed state schematic diagram;

As Fig. 1,2, when the utility model is opened, driving handle 15 makes progress earlier, handle 15 is upwards moved in the elongated slot of handgrip 13 sides, the stroke adjustment step 14 that drives on the core bar 12 upwards moves in handgrip 13, compression spring 9, make spring 9 storage elasticity energy, pin with switch 11, last pushing handle 15 drives core bar 12 and moves up, and makes the some internal overarm supports 3 of core bar 12 upper ends strut again, be that open at the α angle, angle β between while some outer strut 4 lower ends also opens, and promotes some umbrella frames 2 and opens, and finishes the parachute-opening action.Use the different stroke adjustment step 14 of core bar 12 bottoms to cooperate, just can control some umbrella frame 2 open breadths, realize that umbrella cover opens the adjusting of size with switch 11; When the utility model is received, inwardly press head on Push switch 11 braces, make the pointed dop of the brace lower end of switch 11 break away from stroke adjustment step 14, make spring 9 return that releases energy, drive handle 15 and move down in the elongated slot of handgrip 13, make core bar 12 also move down, then angle α and the β between some internal overarm supports 3 and the corresponding some outer struts 4 goes to zero, some umbrella frames 2 are received, and finish the action that closes one's umbrella.Because be empty between the umbrella crown 1 of hinged some umbrella frames 2 upper ends and the pin head 5, for increasing the rigidity of umbrella frame 2, umbrella frame 2 also can adopt flat frame structure.

The utility model can be opened certainly to fall certainly, and the amplitude of opening is adjustable, bring great convenience for people's use, and the utility model is simple in structure, and its parts and existing umbrella have good versatility, and be with low cost.
