【従来の技術】[Prior art]

普通にドアと言えば回動扉をさすくらいに、建物に回動扉はつきものである。 従来、回動扉の支持機構、自動閉扉回動機構に関しては種々の改善が行なわれ、 その形態、外観も向上している。しかし安全面についての工夫が行なわれた例を 知らない。 Speaking of doors as usual, a rotating door is attached to a building as much as a rotating door. Conventionally, various improvements have been made to the support mechanism of the rotating door and the automatic closing and rotating mechanism, and the form and appearance thereof have also been improved. However, I don't know any examples of safety measures.

【考案が解決しようとする課題】[Problems to be solved by the device]

引き戸の場合、戸と建物躯体との間に手を挟んでも、すぐ引抜くことが出来る 。戸を閉じる力と手を挟む力が等しいから、よほど勢いよく閉めないかぎり、問 題はない。 しかし回動扉の場合は、閉扉機構が扉を閉じる力は弱くても、扉の内端と建物 躯体との間に指などを挟みつける力は数十倍になる。本考案者はここに着目し、 事故を未然に防ぐ安全カバーを開発課題として取上げた。 特に不注意な子供と最近多い自動扉とを考え合わせると、安全装置は不可欠と 考える。 In the case of a sliding door, you can pull out immediately even if you put your hand between the door and the building frame. There is no problem unless you forcefully close the door, because the force to close the door is equal to the force to pinch your hands. However, in the case of a swing door, even if the closing mechanism has a weak closing force, the force of pinching a finger or the like between the inner end of the door and the building frame is several tens of times. The inventor paid attention to this and picked up a safety cover as a development issue to prevent accidents. When considering especially careless children and automatic doors, which are often used recently, we think that safety devices are indispensable.

【課題を解決するための手段】[Means for Solving the Problems]

この考案の回動扉の安全装置は、回動扉が閉じる際、扉と建物躯体との間に指 を挟まれるのを防ぐ安全装置であって、後方へ回動する扉の前側で、扉の回動軸 側建物躯体に沿い、安全カバーの回転軸が垂直に取付けられており、上記安全カ バーはほぼ長方形の板であって、垂直姿勢で回動し、バネ付勢によりその先端が 常時、扉の前面から内端にかけて接触を保つようにした事を特徴とする。なお上 記安全カバーは、子供の手が届く範囲を十分覆い得る寸法で、それを超えない大 きさである事が実用的見地から勧められる。 The safety device for a swinging door of this invention is a safety device for preventing a finger from being caught between the door and the building frame when the swinging door is closed. The axis of rotation of the safety cover is installed vertically along the building frame on the side of the building.The safety cover is a rectangular plate that rotates in a vertical position and its tip is biased by a spring. The feature is that the contact is always maintained from the front to the inner edge of the door. In addition, it is recommended from a practical point of view that the safety cover mentioned above should be large enough not to exceed the reach of children and not to exceed it.

【作用】[Action]

この考案が対象とする扉は開くと自動的に閉扉するものである。この考案の安 全カバーは、後方へ回動する扉の前側の建物躯体に軸支持されて回動する。カバ ーの先端が扉の前面を押すよう、カバーはバネ付勢されている。従って扉が後方 へ回動して開くと共に、カバー先端は扉の前面を押しながら摺動し、扉が開きき っても扉の内端に達しないか、達してもはずれる事のない寸法にする。 従って扉が自動で閉じる際は、カバー先端が上述の逆に、扉内端から扉前面へ と摺動して止まり、扉内端と建物躯体との間隙は終始、カバーに覆われるから、 指その他が挟まれる恐れがない。 特に子供を対象にする場合は、カバーの高さは子供の手が届く範囲で足りる。 The door targeted by this invention is automatically closed when opened. The safety cover of this invention is pivotally supported by the building body in front of the door that pivots rearward. The cover is spring biased so that the tip of the cover pushes against the front of the door. Therefore, as the door rotates backward and opens, the tip of the cover slides while pushing the front surface of the door, and does not reach the inner edge of the door even if the door is fully opened, or does not come off even if it reaches. To do. Therefore, when the door closes automatically, the cover tip slides from the inner edge of the door to the front of the door and stops, and the gap between the inner edge of the door and the building frame is covered by the cover from beginning to end. There is no risk of other parts being caught. Especially for children, the height of the cover should be within the reach of children.

【実施例】【Example】

図１はこの考案一実施例の正面図で、回動扉を１、その内端を１ａ、建物躯体 をＡ、回動軸（蝶番）を２、安全カバーを３、その回転軸を４、回転軸４を建物 躯体Ａに取付けたブラケットを５、カバー３を回転させる付勢用バネを６として いる。 図２はその部分拡大図で安全カバー３がその回転軸４をブラケット５に回転自 在にさし込み、バネ６の爪６ａにより回動付勢される機構の一例を示す。７はバ ネ６の他端を押さえた止めネジである。 FIG. 1 is a front view of one embodiment of the present invention, in which a revolving door is 1, an inner end thereof is 1a, a building frame is A, a revolving shaft (hinge) is 2, a safety cover 3 is, and its revolving shaft is 4, The rotary shaft 4 has a bracket 5 attached to the building body A, and the biasing spring 6 for rotating the cover 3 is 6. FIG. 2 is a partially enlarged view showing an example of a mechanism in which the safety cover 3 inserts its rotating shaft 4 into a bracket 5 so as to rotate and is biased by a pawl 6a of a spring 6 to rotate. A set screw 7 holds the other end of the panel 6.

【０００７】 図３はこの考案実施例の平面図で、扉１の内端１ａと建物躯体Ａが僅小間隙で 対向している。この例では安全カバー３が少し湾曲した矩形板で、その回動端で ある先端垂直辺が扉１の前面に隙なく接している。扉１が鎖線で示す１´の位置 まで全開すると、カバー３´の先端が扉前面と内側端面との境の角部に接してい る。 図４はこの考案の他の実施例平面図である。この場合はカバー３を支持するブ ラケット５が板状で、建物躯体Ａに平らに取付けられ、その先端に回転軸４を受 けている。カバー３はこの例では湾曲しない平面板である。FIG. 3 is a plan view of the embodiment of the invention, in which the inner end 1a of the door 1 and the building frame A face each other with a small gap. In this example, the safety cover 3 is a slightly curved rectangular plate, and the pivoting vertical end of the safety cover 3 contacts the front surface of the door 1 without gap. When the door 1 is fully opened to the position 1'shown by the chain line, the tip of the cover 3'is in contact with the corner of the boundary between the door front surface and the inner end surface. FIG. 4 is a plan view of another embodiment of the present invention. In this case, a bracket 5 that supports the cover 3 is plate-shaped, is flatly attached to the building frame A, and receives the rotating shaft 4 at its tip. The cover 3 is a flat plate that is not curved in this example.

【考案の効果】[Effect of device]

図５はさらに他の実施例で、この場合の回動扉１の主体は板ガラスである。そ の回動軸２´は天井と床面から垂直に出て、図を略した上下の枠材に係合してい る。この様式の扉は室内、室外両方向へ回動するものが多いが、この考案を適用 する場合は一方向に限定する。図の矢印方向にだけ開閉させるのである。 以上、少数の実施例について説明したが、この考案はその要旨を変えることな く、扉、建物躯体の実状に応じて多様に変化、応用し得ること言うまでもない。 特に安全カバーを透明板にするとか、模様入りにするとかの形状、材質や、その 回転軸を建物躯体に取付ける方法、バネ付勢の方法等、デザイン面、機械設計面 で工夫の余地が大きい。 FIG. 5 shows still another embodiment, in which the main body of the revolving door 1 is plate glass. The rotary shaft 2'is vertically projected from the ceiling and the floor and is engaged with upper and lower frame members (not shown). Many doors of this style rotate in both indoor and outdoor directions, but when applying this device, the door is limited to one direction. It is opened and closed only in the direction of the arrow in the figure. Although a few examples have been described above, it is needless to say that the present invention can be variously changed and applied according to the actual conditions of doors and building frames without changing the gist thereof. In particular, there is a lot of room to devise in terms of design and mechanical design, such as the shape and material of the safety cover being a transparent plate or having a pattern, the method of attaching its rotating shaft to the building frame, the spring biasing method, etc. .

【考案の効果】[Effect of device]

この考案は回動扉が自動的に閉じる際、子供が無意識に扉内端と建物躯体との 間に指を入れると、閉じる力の数十倍の力で指が挟圧される事実を警告し、その 対策である安全装置を提示した。安全装置としては極めて簡素で、取付けも容易 である。従って、既設の建物にも容易に取付けることができる。 This invention warns the fact that when a swing door automatically closes, if a child unknowingly puts a finger between the inner edge of the door and the building frame, the finger will be pinched with a force that is several tens of times the closing force. Then, he presented the safety device as a countermeasure. The safety device is extremely simple and easy to install. Therefore, it can be easily installed in an existing building.
