The specific embodiment
Consult Fig. 1-13, the present invention includes: rod 1 in, manage 1a, 1b, 1c, 1d, 1e, 1f and 1g for 7 that contain mutually flexible fit; One umbrella frame assembly 2, pivot connect the last nest 20 on excellent top in this and nest 3 (or " safety down nest ") once, and this time nest 3 sleeves on the nest sleeve pipe 11, and this bottom hub sleeve 11 is located at or is sheathed in this on rod 1.
In all pipe 1a～1g of rod be from outermost tubes (the 1st pipe) 1a to interior pipe (the 7th pipe) 1g, promptly progressively increase progressively the number that is arranged with the inner fovea part V on this pipe respectively from outside to inside.
Respectively the longitudinal axis X indent of this inner fovea part V for defining towards middle excellent center from the circumference of this pipe (wall) respectively is as the criterion with a circle 360 degree, and respectively this inner fovea part V is the central angles (Fig. 2) that define one 60 degree, and respectively the central angle of this inner fovea part V is less than 90 degree.
In excellent all pipes increase progressively the number of its inner fovea part V by outermost tubes 1a gradually towards interior pipe 1g, in fact, be progressively to increase progressively an inner fovea part V to its adjacent interior pipe from an outer tube.
Therefore, the inner fovea part V number of each pipe of rod is as described below among the present invention:
Middle rod pipe (sequence number) inner fovea part V number
The 1st pipe or outermost tubes 1a 0V (0 inner fovea part or nothing contain inner fovea part)
The 2nd pipe 1b...............1V (1 inner fovea part)
The 3rd pipe 1c...............2V (2 inner fovea parts)
The 4th pipe 1d...............3V
The 5th pipe 1e...............4V
The 6th pipe 1f...............5V
The 7th pipe or interior pipe 1g...6V
Therefore, adjacent two pipes among the present invention, promptly the number of respectively managing inner fovea part V of inner and outer pipe is to differ 1 inner fovea part V, that is the V number of interior pipe increases by 1 inner fovea part V than its adjacent outer tube.
Outer tube (for example the 1st pipe) 1a contains 0 inner fovea part V, and promptly it forms complete justifying and do not have (or having 0) inner fovea part V around axle X on its circumference; Adjacent in the pipe 1b then contain 1 inner fovea part V, so and between the circumferential wall of outer tube 1a formation one air chamber A.This air chamber A will make adjacent two pipe 1a in the process of opening, close one's umbrella, give the pipeline of circulation of air between the 1b and can prevent violent CONTACT WITH FRICTION, and the circle of excellent all pipes is along flexible, sliding closing operation in can urging.
In like manner, define another air chamber A between the 2nd pipe 1b and the 3rd pipe 1c, as shown in Figure 5, can promote adjacent two pipe 1b, the circle between 1c closes or coupling along sliding.
Thus, the inner fovea part V of the inner fovea part V of outer tube and corresponding interior pipe is sliding mutually closes or coupling.With Fig. 4 and 5 is example, the 2nd pipe 1b comprises that its center of curvature of inner fovea part V (is benchmark with circle 360 degree) " location " is at 330 degree (Fig. 4), and the corresponding inner fovea part V of the 3rd pipe 1c, wherein the center of curvature of an inner fovea part V also is positioned at 330 degree (Fig. 5), closes or coupling along sliding so two inner fovea parts are mutual circle; The center of curvature of another inner fovea part V of the 3rd pipe 1c then is positioned at 150 degree (shown in Figure 5), this with the circumferential part of corresponding the 2nd pipe 1b between formation one air chamber A.The corresponding two inner fovea part V of adjacent two pipes coincide mutually, thus can prevent out, when closing one's umbrella in the axial rotation or the twisting of excellent pipe, thereby promote to open, when closing one's umbrella all pipes circle along and sliding reliably closing with flexible operated; The pipeline that then provides an air to flow as for the air chamber A between adjacent two pipes, in excellent all Guan Yukai in can preventing, the telescopic process that closes one's umbrella by the phenomenon of friction retardance or " killing ", and can guarantee many folding umbrellas open, bring drill to an end that it is smooth-going and slick and sly to do.
Because of the central angle of each inner fovea part V is 60 degree, promptly less than 90 degree, so increasing to, the interior Guan Ze that contains 1 inner fovea part V to the 7 pipe 1g from the 2nd pipe 1b contains 6 inner fovea part V, so can get 7 and roll over umbrellas, also can make many folding umbrellas fold back " ultrashortization ", this can't expect or reach by preceding case.
Ultrashort umbrella of the present invention can significantly reduce its volume and be convenient to collection or accumulating after folding.
