それがあった。Rotating lift doors for external structures, which are convenient doors, often do not necessarily need to be sealed. Therefore, even if the lower end of the decorative board (s) may rise slightly from the dirt floor when the door is closed, it is still useful; however, if a large child or the like inadvertently gets on the door when it is closed, the support arm etc. There was a risk of damage or deformation.

１０ｃｍにも達すると、つまずいて車や人の出入りにも
支障となる欠点があった。For this reason, methods such as installing a door stopper bottle protruding from a part of the lower end of the shield, or raising a part of the earthen floor so that it touches the door have been considered, but the bottle protruding from the lower end of the shield has been considered. This means an increase in the maximum trajectory of the door during opening and closing operations, which obstructs the passage of traffic.Not only does the raised part of the earthen floor look unsightly, but if it reaches a height of 10cm, it can cause people to trip and hinder the ingress and egress of cars and people. There were drawbacks.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

本発明の技術的課題は、扉の下端からビンを突設したり

の下方外力に対して有効な手段を提供することである。The technical problem of the present invention is to provide an effective means against downward external force on the door when the door is closed, without protruding a bottle from the lower end of the door or raising the earthen floor.

and a decorative board ( In a rotary lift door consisting of a door) 1, which closes when the door is in a lowered position and is vertical, and opens when it is in a raised position and approximately horizontal, the lower end of at least the negative side edge of the door 1 when the door is closed. A branch 7 having a rotation surface parallel to the rotation surfaces of the second support arms 21 and 22 is rotatably pivoted near 11, and the branch 7 is always vertically downward and has the above-mentioned Pivot 7
The structure is characterized in that it has a ground-contacting bottom surface 7a that is sufficient to prevent it from easily falling over due to vertically downward external force applied from the bottom. Note that 31 and 32 are columns that support the shaft supports 41 and 42 on the ground, and are also equipped with springs to reduce the weight of rotating parts such as the door 1, and stoppers that limit the rotation stroke of the support arms 21 and 22. is provided separately, but is not shown for the sake of clarity. Further, the second digit 2.1 used in this specification indicates the left and right sides of the support arm system, although some of them are not shown, but they appear the same as those of other systems.

開扉時に１１側端から横り字型に垂下した支片７はほと
んど通行の支障とならないことは自明であろう。Since the present invention has the above configuration, when the door is opened, the support piece 7
hangs further downward from the lower end 11 of the side end of the door l via the pivot Y. At this time, even if a downward external force is applied to the door 1, the bottom surface 7a of the support piece 7 will come into contact with the ground surface immediately or shortly, so the system including the support piece 11 and the support piece 7 will become a rigid body as a whole.
It is possible to resist the unexpected downward external force of if, and to ensure safety. When fil starts to rise in the direction of opening the door, since the support piece 7 is always pointing vertically downward from the pivot joint 7, the trajectory of the lower edge of the door l and the bottom surface 7a of the support piece 7 is almost the same. There is no difference, and the anxiety of the branch 7 protruding into traffic is eliminated, and safety in traffic can also be ensured. On the other hand, since there is no need to raise the earthen floor or place what is commonly called a geta, not only does the appearance not look ugly, but there is also no need to worry about tripping over cars or people when entering or exiting. The bottom surface 7a of the support piece 7 does not necessarily need to be entirely grounded as long as its peripheral portion is grounded. In a sloping area, it is more useful if the earthen floor that contacts the bottom surface 7a is leveled horizontally. Although the total height of the support piece 7 may be insufficient on a horizontally sloping site, it can be adjusted by making it long in advance and making the − of the pivot point Y relative to the side end of the gl freely selectable. or,
It is obvious that the branch 7 which hangs down from the side edge 11 in a horizontal shape when the door is opened hardly becomes an obstacle to passage.

〔発明の効果〕〔Effect of the invention〕

本発明によれば、土間の外観をことさら損なうことなく
、往来や出入りの通行の障害とならない閉扉時の扉ｌの
下方安全手段を得ることができる。According to the present invention, it is possible to obtain a safety means for lowering the door l when the door is closed, which does not impede traffic or entry and exit without particularly damaging the appearance of the dirt floor.

又、開扉時の扉１を閉扉操作するとき、支片７に把手な
どを付設しておけば閉扉操作がより至便になる利点があ
る。Further, when the door 1 is opened and the door 1 is closed, there is an advantage that the door closing operation becomes more convenient if a handle or the like is attached to the support piece 7.
