Problems solved by technology

However, when folding the main ribs, if the number of combined ribs is large, the combined ribs themselves must be supported as a supported combined rib, and the volume of the entire umbrella becomes larger when folded, causing problems is not possible to miniaturize

Embodiment Construction

[0012] The present invention will be described in detail below with reference to the embodiments of the present invention.

[0013] Reference numeral (2a) designates a shaft at the lower end of which the handle (4) is fixed. A sliding shaft (2b) is fitted and assembled on the shaft (2a), and a sliding shaft (2c) is fitted on the sliding shaft (2b).

[0014] On the upper end of the sliding shaft (2c), an upper construction element (8) with a protrusion is fixed. The shaft (2a) and the sliding shafts (2b), (2c) constitute an extendable core-type intermediate rod (2). Numeral (10a) indicates the first rib, one end of which is slidably supported on the upper element (8) with a pivot.

[0015] The first ribs (10a) are fitted several around the upper element (8) and are pivotally supported. In the accompanying drawings, in order to clearly understand the structure of the present invention, only one, namely the first rib, is shown, while the other first ribs are omitted in the acc...

Abstract

To constitute a compact folding umbrella. The one-side ends of master ribs (10) consisting of four pieces of ribs pivotally supported with each other are pivotally supported at an inside cap (8). The master ribs and a lower runner (5) are connected by stretchers (22). The respective ribs of the master ribs are folded in a beeline cooperatively with the vertical sliding of the lower runner. A slide crook and slope are formed at the third rib (10c) among the ribs of the master ribs, by which the ribs are situated next to each other without the superposition of the segment (10c') of the third rib on the side opposite to the pivotally supporting portion (16) of the second rib (10b) on each other. A quadrilateral link mechanism (34) is constituted by a link rib between the stretcher and the second rib of the master rib. The first rib (10a) and the fourth rib (10d) are connected by a connecting shaft (46) and the second rib and the fourth rib (10d) are connected by a connecting shaft (46). As a result, the quadrilateral link mechanism (44) and (52) are constituted between the connecting shaft (36) and the master ribs and between the connecting shaft (52) and the master ribs.

Description

technical field [0001] The invention relates to a portable retractable umbrella. Background technique [0002] In this portable retractable umbrella, the folded main rib usually consists of two or three ribs. [0003] When increasing the number of ribs that make up the main rib, in order to shorten the length of the main rib when it is folded, and to realize the miniaturization of the overall umbrella in its length direction, the main rib should be designed like a telescopic member. However, when folding the main ribs, if the number of combined ribs is large, the combined ribs themselves must be supported as a supported combined rib, and the volume of the entire umbrella becomes larger when folded, causing problems It is impossible to achieve miniaturization. [0004] The object of the present invention is to solve the above-mentioned problems. Contents of the invention [0005] The present invention relates to a compact retractable umbrella. [0006] The present inven...
