[0001]
BACKGROUND 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]
[Prior art]
When wet umbrellas are brought into the train during busy hours, the wet surface of the upholstery cloth touches the clothes of the trousers and skirts of the passengers in the train and wets them, causing inconvenience. The effect was terrible. In addition, when a wet umbrella is newly stored in an umbrella stand, it may cause other umbrellas that are stored adjacent to the umbrella stand to get wet, or an umbrella may be placed on the umbrella stand rather than a wet umbrella. When trying to store or when trying to remove an umbrella housed in an umbrella stand rather than a wet rain umbrella, the wet surface of the umbrella wets the hands and clothes of the umbrella stand user. I also felt uncomfortable.
[0003]
In addition, when riding on a private car or a shared bus on rainy days, if you try to close the umbrella with the action of getting in, a lot of water droplets may splash on your hand or you may fall into the wetness of the floor and seats in the car In many cases, it was inevitable that water droplets would hang around when opening the umbrella in a hurry when getting off.
[0004]
In order to eliminate such inconvenience, conventionally, a rain umbrella having a structure in which a wet umbrella cloth does not appear on the surface has been proposed. Japanese Patent Laid-Open Nos. 3-37005, 4-67803, 2000-37217, etc. Discloses an umbrella having a structure in which the surface of the umbrella cloth of each umbrella can be inverted and accommodated inside. For example, according to Japanese Patent Laid-Open No. 4-67803, upper and lower slidable bearings are provided on a central shaft having a butt at the upper end and a grip at the lower end, and a retractable stopper for engaging and disengaging each bearing is provided. A plurality of main bones each having a seat portion attached to an upper bearing and pivotally attached to each of the base bones; A tip for bending is pivotally attached to the main bone, and an inversion assisting device capable of changing the length of the main or auxiliary bone is provided. The inversion assisting device is one of the divided main bone or auxiliary bone. And a guide case that is slidably guided to another main bone or auxiliary bone, and a compression spring interposed between the opposed end surfaces of the divided main bone or a tension spring interposed between the opposed end surfaces of the divided auxiliary bone And operate the upper and lower stoppers When the upper and lower bearings are moved along the central axis, they are shortened by pressing the compression spring with the main bone connected to the upper bearing interposed therebetween, or the tension spring connected to the lower bearing is Depending on whether it extends by pulling, the upper bearing approaches the lower bearing, whereby the seat portion and the bone portion are inverted and stored in that state.
[0005]
The umbrella according to the above invention divides a predetermined position of a plurality of main bones or auxiliary bones, and fixes the inversion assisting device to each of the divided portions, and also includes a compression spring interposed in the main bone or a tension interposed in the auxiliary bone. Since the structure is such that the seat portion and the bone portion are reversed by the action of the spring, the structure itself is complicated, and there is a disadvantage that the weight must be excessive.
[0006]
In addition, when shaking the umbrella with a large amount of rain on the closed umbrella and trying to remove the attached water droplets, if the components of the umbrella's bone become complicated, the flow of the water droplets will be hindered and more than necessary for draining water. Conventionally, centrifugal force is applied to the tip side of the umbrella, but sufficient centrifugal force is not applied to the handle side, and it is actually impossible to drain water against the user's will. .
[0007]
[Problems to be solved by the invention]
The present invention has been made for the purpose of preventing the adverse effects caused by water droplets on surrounding people's clothing and surrounding objects due to the wet umbrella as described above. When using it occasionally, or when closing a wet umbrella after use, the wet surface of the upholstery fabric is housed inside with an extremely simple structure and easy operation, so there is no adverse effect due to water drops around it. It is another object of the present invention to provide an umbrella having a structure that does not exert a sufficient effect and that can drain water sufficiently.
[0008]
[Means for Solving the Problems]
A parasol according to the present invention for solving the above-mentioned problems is a tubular shaft rod having a stone butt fixed to one end and a handle attached to the other end, and a shaft attached to the shaft rod, and a bottom wheel at the upper end. A substantially cylindrical sliding piece which is slid to the stone thrust side when the umbrella is opened and is held by the shaft rod by an elastic locking means, and which is slid to the handle side when the umbrella is closed. And an upper rod fixed to the shaft rod, one end pivotally attached to a second fulcrum provided on the upper rod, and the other end of the shaft rod. A third support bone that is pivotally attached to a second support shaft provided at one end of a plurality of main bones that are symmetrically extended to the axial center of the shaft, and one end at a first fulcrum provided at the lower end of the stone thrust. Are pivotally attached to each other and extend along the corresponding main bone, and the other end is attached to a first support shaft provided on the main bone. One end is pivotally attached to the first supporting bone and the third fulcrum provided on the lower pole, and is extended along the corresponding main bone and third supporting bone, respectively, and the other end is the main bone. The second support shaft provided on the second support shaft includes a second support bone that is pivotally attached together with the third support bone, and a tension cloth that is stretched so as to cover the outside of the first support bone and the main bone. It is a characteristic component requirement.
[0009]
According to the present invention having the above configuration, when the umbrella is closed from the opened state, the lock of the sliding piece by the elastic locking means is released, and as the sliding piece moves in the pattern direction, it becomes concave toward the handle side. The open main bone is inverted in a convex shape toward the handle at a predetermined position, and the free end side of the main bone and the first support bone are centered on the first support axis, and the main bone and the second support bone Are folded so as to approach each other around the second support shaft, and the tension cloth stretched outside the first support bone and the main bone also has a cross section between the free end side of the main bone and the first support bone. Since it is folded in a substantially W shape, the wet surface is not located outside the closed umbrella.
