Description

【0001】
【発明の属する技術分野】
この発明は、ドアの開き角度を制限するドアガードの受け具の支持装置に関するものである。
【0002】
【従来の技術】
ドアガードは、ドアの戸先側内面に取付けられる取付座と、その取付座に起伏自在に連結されたU字形の係合アームと、ドア枠のたて枠内面に取付けられる受け具とから成り、上記受け具に対する係合アームの係合によってドアの開き角度を制限するようにしている。
【0003】
【発明が解決しようとする課題】
ところで、上記ドアガードにおける受け具の取付けに際して、従来は、たて枠に受け具をビス止めする取付けであるため、係合アームが受け具と係合する係合位置において、万一地震が発生し、ドア枠が菱形に変形してドアの戸先側に下向き方向あるいは上向き方向の荷重が作用すると、係合アームと受け具の係合部に衝撃力が作用する。このとき、係合アームが変形すると、その係合アームを受け具に対して係合解除することができず、ドアを開放して屋外に逃げ出すことができない場合が生じる。
【0004】
この発明の課題は、受け具に係合アームが係合する係合位置において、その係合アームから受け具に衝撃力が作用しても、係合アームの変形を防止できるようにした受け具の支持装置を提供することである。
【0005】
【課題を解決するための手段】
上記の課題を解決するために、この発明においては、ドアの戸先側内面に起伏自在に取付けられた係合アームと、ドア枠のたて枠に取付けられた受け具との係合によってドアの開放角度を制限するドアガードにおける受け具の支持装置において、前記受け具の端部に設けられた座板の上下部に上下方向に長い長孔を形成し、上記座板とたて枠の表面間に、両側部に折曲片を有するばね座金を組込み、そのばね座金に上記長孔に余裕をもって挿入されるビス挿入筒を設け、このビス挿入筒の長さを前記座板に形成された長孔の深さより短くし、上記座板の表面からビス挿入筒に挿入されるビスの締付けによって受け具を取付けた構成を採用している。
【0006】
上記のように構成すると、ビスの締付けによる受け具の取付け状態において、受け具の座板は、ビスの頭部とばね座金とで両側から弾力的に挾持されるため、係合位置に保持された係合アームから受け具に上方又は下方からの衝撃力が作用すると、受け具は、衝撃力が作用する方向に移動して衝撃力を吸収する。このため、係合アームは受け具との衝突によって変形するのが防止される。
【0007】
【発明の実施の形態】
以下、この発明の実施の形態を図面に基づいて説明する。
【0008】
図1および図2に示すように、ドア枠1の出入口2を開閉する回動自在に支持されたドア3の内面における戸先側には取付座4が取付けられている。
【0009】
取付座4は上下で対向する支持片5を表面に有し、その支持片5間にU字形係合アーム6の両端部が配置されている。係合アーム6の各端部と支持片5は、ピン7で連結され、そのピン7を中心として係合アーム6が回動し得るようになっている。
【0010】
また、取付座4には、各支持片5の内面に沿って収納孔8が形成され、その収納孔8内に底板9と、この底板9を係合アーム6の端部に押圧する弾性体10とが組込まれ、上記弾性体10によって係合アーム6はピン7に向けて押圧されており、係合アーム6は、ドア3の内面に沿う係合解除位置とドア3の内面から起立する係合位置のいずれかに保持されるようになっている。
【0011】
係合アーム6の内周には、その係合アーム6の両端方向に延びる突条11が設けられている。
【0012】
ドア枠1のたて枠1aの内面には受け具12が取付けられている。受け具12は座板13を端部に有し、その座板13の上下部に上下方向に長い長孔14が形成され、各長孔14の端部に長円状の座15が設けられている。
【0013】
上記受け具12は、ドア3の閉鎖状態において、ドア3の内面に沿う係合解除位置の係合アーム6を係合位置に回動したとき、先端部が係合アーム6の両端部間に挿入される位置に取付けられ、その先端部の上下には、係合アーム6の突条11がスライド自在に挿入可能のガイド溝16が設けられている。
【0014】
図1は、ドア3の閉鎖状態において、係合アーム6を係合位置に回動した状態を示し、その状態においてドア3を開放すると、ガイド溝16に沿って突条11がスライドして係合アーム6の端部が受け具12と係合し、その係合によってドア3の開き角度が制限される。
【0015】
上記受け具12の取付けに際し、図3および図4に示すばね座金17が用いられている。ばね座金17は背面側に折れ曲がる折曲片17aを両側に有している。また、ばね座金17の表面における上下部には、受け具12の長孔14に少しの余裕をもって挿入されるビス挿入筒18が設けられ、各ビス挿入筒18の長さLは長孔14の深さHより短くなっている。
【0016】
受け具12は、座板13の表面からビス挿入筒18内に挿入されてたて枠1aのねじ孔20にねじ込むビス19の締付けにより固定される。その固定状態において、ばね座金17の折曲片17aが弾性変形し、その折曲片17aの弾力により、長孔14上に設けた座15がビス19の頭部19aに押し付けられる。このため、受け具12は、座板13がビス19の頭部19aとばね座金17によって表裏両側から弾力的に挾持される取付けとされる。
【0017】
上記のように、受け具12をビス19の頭部19aとばね座金17とで弾力的に挾持する取付けとすることにより、受け具12に上向き又は下向きの衝撃力を受けると、その衝撃力が座板13とばね座金17の接触部の摩擦抵抗より大きい場合に、受け具12は荷重の方向に移動する。
【0018】
このため、図1に示すように、係合アーム6が係合位置に回動された状態において、地震によりドア枠1が菱形に変形してドア3の戸先側が上方向又は下方向に押し上げられ、係合アーム6を介して受け具12に衝撃力が加わると、受け具12は衝撃力が作用する方向に移動して、上記衝撃力を吸収する。
【0019】
したがって、係合アーム6が受け具12に対する衝突によって変形するのを防止することができ、ドア3を開放することができなくなるという不都合の発生を未然に防止することができる。
【0020】
【発明の効果】
以上のように、この発明においては、係合アームの係合位置において、その係合アームを介して受け具に上方向又は下方向の衝撃力が作用すると、受け具は、その衝撃力を受ける方向に移動して衝撃力を吸収するため、係合アームが変形し、ドアを開放することができなくなるという不都合の発生を未然に防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a support device for a door guard receiving member for limiting the opening angle of a door.
[0002]
[Prior art]
The door guard is composed of a mounting seat that is attached to the inner surface of the door tip side of the door, a U-shaped engagement arm that is connected to the mounting seat so as to be raised and lowered, and a receiver that is attached to the inner surface of the vertical frame of the door frame. The opening angle of the door is limited by the engagement of the engagement arm with the receiver.
[0003]
[Problems to be solved by the invention]
By the way, when mounting the receiving device on the door guard, conventionally, the mounting method is to fix the receiving device to the vertical frame with screws, so that an earthquake should occur at the engaging position where the engaging arm engages the receiving device. When the door frame is deformed into a rhombus and a load in the downward direction or the upward direction acts on the door tip side of the door, an impact force acts on the engagement portion of the engagement arm and the receiving tool. At this time, if the engagement arm is deformed, the engagement arm cannot be released from the receiving device, and the door may not be opened to escape to the outdoors.
[0004]
An object of the present invention is to provide a receiver that can prevent deformation of an engagement arm even when an impact force acts on the receiver from the engagement arm at an engagement position where the engagement arm engages with the receiver. It is to provide a support device.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, in the present invention, a door is formed by engagement of an engagement arm attached to the door inner surface of the door tip so that it can be raised and lowered and a receiving tool attached to the vertical frame of the door frame. In the support device for the receiver in the door guard that restricts the opening angle of the door guard, a long hole is formed in the upper and lower portions of the seat plate provided at the end of the receiver in the vertical direction, and the surface of the seat plate and the vertical frame A spring washer having bent pieces on both sides was incorporated between the two, and a screw insertion cylinder inserted into the long hole with a margin was provided in the spring washer. The length of the screw insertion cylinder was formed on the seat plate. A structure is adopted in which the receiving tool is attached by tightening a screw that is shorter than the depth of the long hole and is inserted into the screw insertion cylinder from the surface of the seat plate.
[0006]
According to the above configuration, in the mounting state of the receiver by tightening the screw, the seat plate of the receiver is elastically clamped from both sides by the head of the screw and the spring washer, so that it is held in the engaged position. When an impact force from above or below acts on the receiver from the engagement arm, the receiver moves in the direction in which the impact force acts to absorb the impact force. For this reason, the engaging arm is prevented from being deformed by a collision with the receiving member.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0008]
As shown in FIGS. 1 and 2, a mounting seat 4 is attached to the door side on the inner surface of a door 3 that is rotatably supported to open and close the doorway 2 of the door frame 1.
[0009]
The mounting seat 4 has upper and lower opposing support pieces 5 on the surface, and both ends of the U-shaped engagement arm 6 are disposed between the support pieces 5. Each end of the engagement arm 6 and the support piece 5 are connected by a pin 7 so that the engagement arm 6 can rotate around the pin 7.
[0010]
In addition, the mounting seat 4 is formed with a storage hole 8 along the inner surface of each support piece 5, a bottom plate 9 in the storage hole 8, and an elastic body that presses the bottom plate 9 against the end of the engagement arm 6. 10, and the engagement arm 6 is pressed toward the pin 7 by the elastic body 10, and the engagement arm 6 stands up from the engagement release position along the inner surface of the door 3 and the inner surface of the door 3. It is held at one of the engagement positions.
[0011]
On the inner periphery of the engagement arm 6, a protrusion 11 is provided that extends in the direction of both ends of the engagement arm 6.
[0012]
A support 12 is attached to the inner surface of the vertical frame 1a of the door frame 1. The support 12 has a seat plate 13 at its end, elongated holes 14 that are long in the vertical direction are formed in the upper and lower portions of the seat plate 13, and an oval seat 15 is provided at the end of each elongated hole 14. ing.
[0013]
When the engagement arm 6 at the disengagement position along the inner surface of the door 3 is rotated to the engagement position in the closed state of the door 3, the receiving end 12 has a tip portion between the both ends of the engagement arm 6. A guide groove 16 is provided at the insertion position, and above and below the tip of the engagement arm 6 so that the protrusion 11 of the engagement arm 6 can be slidably inserted.
[0014]
FIG. 1 shows a state in which the engagement arm 6 is rotated to the engagement position in the closed state of the door 3. When the door 3 is opened in this state, the protrusion 11 slides along the guide groove 16 and engages. The end of the combined arm 6 is engaged with the receiving member 12, and the opening angle of the door 3 is limited by the engagement.
[0015]
When the receiver 12 is attached, a spring washer 17 shown in FIGS. 3 and 4 is used. The spring washer 17 has bent pieces 17a that bend on the back side on both sides. Further, screw insertion cylinders 18 are provided on the upper and lower portions of the surface of the spring washer 17 so as to be inserted into the long holes 14 of the support 12 with a slight margin. The length L of each screw insertion cylinder 18 is the length of the long holes 14. It is shorter than the depth H.
[0016]
The support 12 is fixed by tightening a screw 19 that is inserted into the screw insertion cylinder 18 from the surface of the seat plate 13 and screwed into the screw hole 20 of the vertical frame 1a. In the fixed state, the bent piece 17a of the spring washer 17 is elastically deformed, and the seat 15 provided on the elongated hole 14 is pressed against the head 19a of the screw 19 by the elasticity of the bent piece 17a. For this reason, the receiving member 12 is attached so that the seat plate 13 is elastically held from both the front and back sides by the head 19 a of the screw 19 and the spring washer 17.
[0017]
As described above, when the receiving device 12 is elastically held by the head 19a of the screw 19 and the spring washer 17, when the receiving device 12 receives an upward or downward impact force, the impact force is reduced. When the friction resistance of the contact portion between the seat plate 13 and the spring washer 17 is greater than the friction resistance, the support 12 moves in the direction of the load.
[0018]
For this reason, as shown in FIG. 1, in a state where the engagement arm 6 is rotated to the engagement position, the door frame 1 is deformed into a rhombus due to the earthquake, and the door end side of the door 3 is pushed upward or downward. When an impact force is applied to the receiving tool 12 via the engagement arm 6, the receiving tool 12 moves in the direction in which the impact force acts and absorbs the impact force.
[0019]
Therefore, it is possible to prevent the engagement arm 6 from being deformed due to a collision with the receiving member 12, and it is possible to prevent inconvenience that the door 3 cannot be opened.
[0020]
【The invention's effect】
As described above, according to the present invention, when an impact force in the upward or downward direction acts on the receiver via the engagement arm at the engagement position of the engagement arm, the receiver receives the impact force. Since the impact force is absorbed by moving in the direction, it is possible to prevent inconvenience that the engagement arm is deformed and the door cannot be opened.
