【発明の詳細な説明】 本発明は傘を開いたとき天蓋部が主として楕円
形状になる傘に開するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is an umbrella in which the canopy is mainly oval when opened.

従来の殆んどの傘は、開いたとき天蓋部が円形
で且つ柄が天蓋部の中心に位置しているため、傘
を持つた手により天蓋部が差す人の左右或いは前
後に片寄り、差している人の左右或いは前後の片
寄つた反対側を濡らすことが多い。 Most conventional umbrellas have a circular canopy when opened, and the handle is located in the center of the canopy, so the canopy may shift to the left or right or front and back of the person holding the umbrella, causing the person to hold the umbrella to the left or right, or to the front or back. It is common to wet the left and right sides of the person who is wearing the towel, or the opposite side of the person in the front and back.

このようなことを防止するため、傘を開いた
（以下開傘と云う）ときの天蓋部が略楕円形状に
なる種々の傘が提案されている。 In order to prevent this, various types of umbrellas have been proposed in which the canopy section has a substantially elliptical shape when the umbrella is opened (hereinafter referred to as "open umbrella").

が煩わしいなどの欠点がある。 According to Utility Model Registration Publication No. 4565 of 1932 (hereinafter referred to as Reference 1), lengths are added to the ribs on which the umbrella cloth is stretched so that when the umbrella is opened, the canopy has a roughly elliptical shape that extends to one side. , a short support bone is pivotally connected to the short main bone, a long support bone is pivoted to the long main bone, and a plurality of rotor tubes, in which the tips of the support bones of the same length are pivoted, are connected to the short support bone. It is an umbrella with a handle placed in a slidable manner, with the potter's wheel tube placed on the top and the potter's wheel tube, which has long spines, placed on the bottom. In this case, when the umbrella is folded (hereinafter referred to as "closed umbrella"), the ribs around the handle have long and short lengths, making it very unsightly in appearance and difficult to use.Furthermore, the overall length when the umbrella is closed increases. There are drawbacks such as cumbersome handling.

外観的に改善されているものの、開傘したり閉傘
するとき長い親骨の先端部分を一々手で起したり
折つたりしなければならず使用のさい極めて面倒
であると云う欠点がある。 The umbrella according to Utility Model Publication No. 51-19952 is cited in Reference 1.
The gist of this is that all the lengths of the supporting bones are the same, there is only one sliding potter's wheel, and the tips of the long main ribs can be folded outward, but compared to Reference 1, Although the structure is simplified and the appearance is improved, when opening or closing the umbrella, the tip of the long rib must be raised and broken by hand, which is extremely troublesome to use. There is a drawback.

長も可成長くなつて取扱いが煩わしく、またロク
ロの構造が複雑なため製作費が高くつくことにな
るなど欠点がある。 The umbrella according to Utility Model Publication No. 1989-8927 uses a potter's wheel tube instead of the plurality of potter's wheel tubes in Reference 1 by providing a vertical groove on the outer circumferential surface so that the pivot point at the proximal end of the support bone can be moved. The main idea is to reduce the number of potter's wheels to one, but although the number of potter's wheels has been reduced and handling has been made easier, as in the case of Reference 1, the ribs that are close to the handle when the umbrella is closed are long and short. It has drawbacks such as being unsightly in appearance, difficult to use, and cumbersome to handle as the overall length when closed is large, and the complicated structure of the potter's wheel increases production costs.

ものである。 Furthermore, in the umbrella disclosed in Japanese Patent Application Laid-open No. 49-56759, when the umbrella is opened, the canopy part is stretched with an oval umbrella cloth, and the base end of the canopy rib, which can be expanded and contracted via a joint, is attached to the handle. The distal end of the extensible member, whose proximal end is pivotally attached to the main hand potter's wheel, which is pivotally attached to the canopy crown fixed to the upper end and slidably fitted to the handle on the handle side, is attached to the joint joint. A first member which is pivotally attached and is fixed to the handle at the lower part of the canopy crown near the middle of the extending member of the longer canopy rib.
The distal end of a support member whose base end is pivotally attached to the flange, and the lower part of the first flange slides on the handle near the middle of the shorter extending member of the canopy rib. On the auxiliary hand potter's wheel that is freely fitted,
This is a short support member whose base end is pivoted and whose distal end is pivoted.

欠陥を内在している。 Although this umbrella is functionally superior to the three types of umbrellas described above, the distance between the canopy crown and the first flange on the longer canopy rib side, the length of the support member, and the pivot point of the support member The sum of the lengths of the extension member from the landing point to the main hand potter's wheel, the length of the extension member on the shorter canopy rib side, and the joint to which the extension member is pivoted when the umbrella is closed. Depending on how the canopy ribs are set, including the sum of the lengths of the canopy ribs from the joint to the canopy crown, the long and short canopy ribs may not open at the same time when the umbrella is opened, or the umbrella may end up in a half-open state and be completely removed by hand. The disadvantages include that the umbrella must be collapsed, or that all the bones along the handle are in a straight line so that the umbrella cannot be closed. Furthermore, there is no mention of whether or not the tips of all the canopy ribs are aligned to close the canopy. A case is also disclosed in which the first flange is slidably fitted onto the handle, but this case also has some defects.

ある。 The present invention was made to solve these problems, and when the umbrella is opened, it automatically changes from a circular shape to an elliptical shape that extends to both sides, or from a circle to a substantially elliptical shape that extends to one side, or a star shape. Even when the umbrella is closed, the ends of each rib can be folded automatically so that it looks the same as a conventional umbrella, making it less unsightly.The overall length of the umbrella does not increase when it is closed, making it easy to handle. We would like to provide you with an umbrella.

ロクロ５より上方に位置している。 To close the umbrella, the lower potter's wheel 5 is released from the middle rod 1.
When the short rib 31 is moved downward, the short rib 31 is pulled toward the middle rod 1 by the short rib 40 without changing its length. When the lower potter's wheel 5 is further lowered, the short ribs 31 and short struts 40 gradually become in a straight line, and further pushed by the short ribs 31, the short struts 40 and short struts 44 are aligned in a straight line along the middle rod 1. It becomes like this. The lower potter's wheel 5 at this time is the proximal short rib 35
If the length is the length of the short bridge 40 from position D of the lower potter's wheel 5 to the tip 42, it is at a position lowered by + from the upper potter's wheel 2 (lowest position), and the lower middle potter's wheel 4 is at the lower middle position. Short spine 4 from position C of potter's wheel 4 to position K attached to short bridge 40
