Abstract

<P>PROBLEM TO BE SOLVED: To provide a handle for a building door, by which the accident capable of killing a man more than a conventional handle is hardly generated and which can be used safely. <P>SOLUTION: The handle 1 on the pull side has a base body section 3a on the door side and a handle section 4a pulled to this side, and an interior-side end section 9 displaced to this side by the operation of a full pulling to this side of the handle section 4a even under the state of the full pulling is left in the recessed-section space of the base body section 3a. Since an interior-side end section displaced to this side by the operation of the full pulling to this side of the handle section on the pull side under the state of the full pulling is left in the recessed-section space of the base body section, the handle for the building door is formed in a structure in which a cord or the like is difficult to be caught extremely. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
この発明は、安全性が高い建物扉用把手に関するものである。
【0002】
【従来の技術】
従来より、プッシュ・プル型の建物扉用把手が知られている(例えば、特許文献1参照)。
【0003】
図6及び図7に示すように、この建物扉用把手はドア20の両側から把手21を押したり引いたりすることにより錠機能が内蔵されているケーシング22内にラッチ23が没入し得る状態に開錠されてドア20が開きうるものであり、ホテルその他の各種の建築物で広く使用されている。ドア20の両側にある把手21のうち片側(プッシュ側)は押し込むように、他方側(プル側)の把手は手前に引くレバー式形状となっている。
【0004】
ところで、精神的に不安定なかたが入院される病院で、手前に引く方の把手のレバー24に革紐25を引っ掛ける人がいて、前記革紐25を自分の首に巻き付けて吊り下がろうとする危険行為があった。レバー24の床からの高さが約1メートル前後であっても、このような自ら命を絶とうとする事故が起きる可能性を否定できない。

【0006】
【発明が解決しようとする課題】
そこでこの発明は、従来よりも自ら命を絶とうとする事故が起きる可能性が少なく安全に使用することができる建物扉用把手を提供しようとするものである。
【0007】
【課題を解決するための手段】
前記課題を解決するためこの発明では次のような技術的手段を講じている。
▲1▼ この発明の建物扉用把手は、プル側の把手は扉側の基体部と手前に引く把手部とを具備し、前記把手部を手前側一杯に引いた状態でもこの操作により手前側に変位した奥側端部は基体部の凹部空間内に残留するようにしたことを特徴とする。
【0008】
この建物扉用把手は、プル側の把手部を手前側一杯に引いた状態でもこの操作により手前側に変位した奥側端部は基体部の凹部空間内に残留するようにしたので、紐などが非常に引っ掛かかり難い構造となっている。
【0009】
▲2▼ 前記把手部は操作用の切欠部を有する略半球殻状とされたこととしてもよい。
【0010】
このように構成すると、紐などがより引っ掛かかり難い構造とすることができる。
【0011】
【発明の実施の形態】
以下、この発明の実施の形態を図面を参照して説明する。
【0012】
図1乃至図5に示すように、この実施形態の建物扉用把手は、プル側の把手1は扉2に固定する基体部3aと手前に引く把手部4aとを具備する。この把手部4aは、操作用の切欠部5(図5参照)を有する浅い略半球殻状としている。
【0013】
前記プル側の把手1に対し扉2の逆側面には、プッシュ側の把手6を設けている。このプッシュ側の把手6の把手部4bも浅い略半球殻状としており、その基体部3bを扉2に固定している。
【0014】
前記プル側の把手1とプッシュ側の把手6とは共に基体部3に把手部4を一定範囲回動可能に軸支した構造としており、それぞれ開閉操作後の復元用のスプリング7(図5参照)を配設している。また前記各基体部3には、各把手部4への操作を錠機構へと伝達する一対の出力軸8(図3、図5参照)を設けている。
【0015】
そして、前記プル側の把手部1を手前側一杯に引いた状態でも、この操作により元の位置(図5の二点鎖線参照)から手前側に変位したその奥側端部9は基体部3aの凹部空間10内に残留するように回動ストロークを設定している。前記奥側端部9は、浅い略半球殻状の把手部4aの操作用の切欠部5の奥で丸みのある角となっている。
【0016】
ここで、扉2内にはその側端面11から内方に向け延在するケーシング12が装着され、断面三角状の角度が付いているラッチ13は前記ケーシング12の内部に反転かつ進退可能に設けられている。前記ケーシング12内には、ラッチ13を前進位置にロックするロック部材や、前記ロック部材を動作させるスライド部材等の錠機構などが内蔵されている。前記錠機構は、表裏の把手部4を押したり引いたりする操作をすることにより、ラッチ13がケーシング12内に没入し得る状態に開錠されて扉2が開くようにするものである。また前記ケーシング12には、一対の出力軸8から伝達された運動を錠機構を通じてラッチ13へと中継する一対の受力部14 (図4、図5参照)を設けている。前記ラッチ13は締まりを行う部分であり、スプリングによって通常はケーシング12から飛び出しており、把手部4の操作により後退して凹み得る状態となる。
【0017】
次に、この実施形態の建物扉用把手の使用状態を説明する。
【0018】
図1、図2及び図5に示すように、この建物扉用把手は、プル側の把手部1を手前側一杯に引いた状態でもこの操作により手前側に変位した奥側端部9は基体部3aの凹部空間10内に残留するようにしたので(特に図5参照)、紐などが非常に入り難く引っ掛かかり難い構造となっており、従来よりも不慮の事故が起きる可能性が極端に少なく安全に使用することができる。また、前記把手部4aは操作用の切欠部5を有する略半球殻状としており、前記奥側端部9も丸みのある角で紐などが滑り易くなっているのでより引っ掛かかり難い構造となっている。
【0019】
すなわち精神的に不安定なかたが入院される病院で、プル側の把手部4aに革紐などを引っ掛け自分の首に巻き付けて吊り下がろうとしても(なおプッシュ側の把手部4bには紐は引っ掛かからない)、実際に紐を引っ掛けることは極めて困難であって事実上ほぼ不可能であるので危険行為を未然に防止することができるという大きな利点がある。
【0020】
【発明の効果】
この発明は上述のような構成であり、次の効果を有する。
【0021】
紐などが非常に引っ掛かかり難い構造となっているので、従来よりも自ら命を絶とうとする事故が起きる可能性が少なく安全に使用することができる建物扉用把手を提供することができる。

Each of the pull-side handle 1 and the push-side handle 6 has a structure in which the handle portion 4 is rotatably supported on the base portion 3 so as to be rotatable within a predetermined range, and a restoring spring 7 after opening and closing operations (see FIG. 5). ). Each of the bases 3 is provided with a pair of output shafts 8 (see FIGS. 3 and 5) for transmitting an operation to each handle 4 to the lock mechanism.
[0015]
Even when the pull-side handle portion 1 is pulled fully to the front side, the back end 9 displaced from the original position (see the two-dot chain line in FIG. 5) to the front side by this operation is still the base portion 3a. The rotation stroke is set so as to remain in the concave space 10. The rear end 9 has a rounded corner at the back of the notch 5 for operation of the shallow, substantially hemispherical handle 4a.
[0016]
Here, a casing 12 extending inward from the side end face 11 is mounted in the door 2, and a latch 13 having a triangular cross section is provided inside the casing 12 so as to be capable of inverting and moving forward and backward. Have been. In the casing 12, a lock mechanism such as a lock member for locking the latch 13 at the forward position and a slide member for operating the lock member are incorporated. The lock mechanism unlocks the latch 13 so that the latch 13 can be immersed in the casing 12 and opens the door 2 by pushing or pulling the grips 4 on the front and back sides. The casing 12 is provided with a pair of force receiving portions 14 (see FIGS. 4 and 5) for relaying the movement transmitted from the pair of output shafts 8 to the latch 13 through the lock mechanism. The latch 13 is a portion for tightening, and normally protrudes from the casing 12 by a spring, and is retreated by operation of the handle portion 4 so that the latch 13 can be recessed.

Next, the use state of the handle for a building door of this embodiment will be described.
[0018]
As shown in FIGS. 1, 2 and 5, the handle for the building door has a rear end 9 displaced to the front side by this operation even when the handle 1 on the pull side is fully pulled toward the front side. Since it is made to remain in the recessed space 10 of the portion 3a (particularly, see FIG. 5), the structure is such that the string or the like hardly enters and is hardly caught, and the possibility of an accident occurring more than before is extremely high. Less safe to use. The handle 4a has a substantially hemispherical shell shape with a cutout 5 for operation, and the back end 9 also has a rounded corner where a string or the like is easily slipped, so that it is more difficult to be caught. Has become.
[0019]
In other words, in a hospital where mentally unstable people are hospitalized, even if the user pulls the strap on the pull-side handle 4a, wraps it around his neck, and tries to hang it (the push-side handle 4b still has However, it is extremely difficult and practically impossible to actually hook the string, so there is a great advantage that dangerous acts can be prevented beforehand.
