Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an umbrella, and more particularly to an umbrella having a structure for preventing water droplets from adhering to a peripheral object from a wet upholstery cloth.

[0002]

2. Description of the Related Art When wet umbrellas are brought into a train or the like during a crowded time, the wet surface of the upholstery comes into contact with clothes of pants or skirts of nearby users in the train, thereby causing the rain. Often, it causes wetting and annoyance. Also, when newly storing an umbrella that is wet in the rain on an umbrella stand, it may cause other umbrellas housed adjacent to the umbrella stand to get wet, When trying to put it in, or when trying to take out an umbrella that is housed behind the umbrella stand rather than a wet umbrella stand,
The wet surface of the umbrella wet the hands and clothing of the user of the umbrella stand, sometimes causing discomfort. Furthermore, if you bring a wet umbrella when you get on a car, the seats and the like will get wet.

[0003] In order to eliminate such inconveniences,
Umbrellas having a structure in which a wet umbrella cloth does not come out on the surface have been proposed, and are disclosed in JP-A-3-37005 and JP-A-4-67803.
JP-A No. 2000-37217 discloses an umbrella having a structure in which the surface of an umbrella cloth of an umbrella can be accommodated by being turned inward. For example, JP-A-4-6780
According to No. 3, an upper and lower slidable bearing is provided on a central shaft having a stone push at an upper end and a grip portion at a lower end,
A retractable stopper for engaging and disengaging each bearing is provided, and each base end of a plurality of main bones having a seat portion attached to an upper bearing is pivotally connected, and each base end of a plurality of auxiliary bones is pivotally connected to a lower bearing. A tip of the auxiliary bone bent toward the opposing main bone is pivotally attached to the main bone, and an inversion assisting device capable of changing the length of the main bone or the auxiliary bone is provided. A guide case fixed to one of the divided main bones or auxiliary bones and slidably guiding the other main bones or auxiliary bones;
The upper and lower bearings, which are composed of a compression spring interposed between the opposed end faces of the split main bone or a tension spring interposed between the opposed end faces of the split auxiliary bone, and operated by operating the upper and lower stoppers, are free along the central axis. Depending on whether the main bone connected to the upper bearing is shortened by pressing the intervening compression spring or extended by pulling the tension spring connected to the lower bearing, The bearing approaches,
As a result, the seat portion and the bone portion are inverted, and are stored in that state.

The umbrella according to the above invention divides predetermined positions of a plurality of main bones or auxiliary bones, fixes an inversion assisting device to each of the divided portions, and uses a compression spring or auxiliary bone interposed between the main bones. Since the structure is such that the seat portion and the bone portion are reversed by the action of the interposed tension spring, the structure itself becomes complicated, and there is a disadvantage that the weight must be excessive.

Further, in a case where the umbrella is shaken in a state where a large amount of rain has adhered to the closed umbrella to remove the adhered water droplets, if the components of the umbrella bone become complicated, the flow of the water droplets is hindered, and the drainage is difficult. Unnecessary power is required, and centrifugal force is conventionally applied to the tip of the umbrella, but sufficient centrifugal force is not applied to the handle side, and it is not possible to drain enough water against the user's will. Met.
