Embodiment Construction

[0037] Referring to Figures 1-13, the present invention includes: a middle rod 1, containing 7 tubes 1a, 1b, 1c, 1d, 1e, 1f and 1g that are telescopically fitted with each other; an umbrella rib assembly 2, pivotally connected to the middle rod The upper nest 20 at the top and the lower nest 3 (or "safety lower nest"), the lower nest 3 slides on the lower nest sleeve 11, and the lower nest sleeve 11 is arranged or sleeved on the middle rod 1.

[0038] The tubes 1a-1g of the middle rod are from the outermost tube (the first tube) 1a to the innermost tube (the seventh tube) 1g, that is, from the outside to the inside, the number of inner concave parts V recessed on each tube is gradually increased. .

[0039] Each of the inner recesses V is recessed from the circumference (wall) of each tube toward a longitudinal axis X defined by the center of the middle rod. Based on a circle of 360 degrees, each of the inner recesses V defines a central angle of 60 degrees. (FIG. 2), the cen...

Abstract

A multiple-fold umbrella includes a telescopic central shaft having seven tubes telescopically coupled with one another, with an outermost tube having no (or zero) concave portion formed on the outermost tube, and with an innermost tube having six concave portions circumferentially formed on the innermost tube, each concave portion is recessed in the tube centripetally about a longitudinal axis of the shaft and defines a central angle of sixty degrees, and the tubes gradationally increases the number of the concave portions from the outermost tube towards the innermost tube to define an air chamber between a concave portion of an inner tube and a circular periphery of an outer tube neighboring to the inner tube for a smooth slidable coupling of every two neighboring tubes.

Description

technical field [0001] The invention relates to an ultra-short multi-fold umbrella and a rod in the umbrella. Background technique [0002] U.S. Patent 6,035,873 (hereinafter referred to as the "previous case") (note: the Chinese related application of the previous case, patent number: 98117440.X) was also developed by the inventor of this case, which discloses a 15-fold multi-fold umbrella, in which the stick It is formed by telescopic fitting of various tubes, but still has the following disadvantages: [0003] 1. Observe the uppermost (innermost) tube, which has 4 arc-shaped concave quadrants, which gradually increase from the lowermost (outermost) tube (that is, from zero concave quadrants to 4 concave quadrants). If this umbrella is intended to be made into 40% off, then it must be impossible, because a dome can only be divided into 4 quadrants at most, so this previous proposal can only achieve 50% off, and it is impossible to make more folds. [0004] 2. The multi-s...
