Description

本願発明は、自動閉鎖式引き戸の減速用に用いられるエアシリンダーのダンパーロッドの振れ、傾きを防止するガイドブラケットを備えた自動閉鎖式引き戸用エアダンパーに関するものである。   The present invention relates to an air damper for a self-closing sliding door provided with a guide bracket for preventing the swing and tilt of a damper rod of an air cylinder used for deceleration of the self-closing sliding door.

従来から、自動閉鎖式引き戸用エアダンパーは知られており、エアシリンダーのダンパーロッド(ピストンロッド)の振れ、傾きを防止するためにダンパーロッドをロッド受けにより支持することも知られている。このロッド受けの構造は下方面を支持する支持曲部と上方面を支持する付勢バネ曲部よりなるものであり、シリンダー内に設けられてエアシリンダーとダンパーロッドを常時同軸状に支持することを目的としている(特許文献1)。

2. Description of the Related Art Conventionally, an air damper for a self-closing sliding door is known, and it is also known to support a damper rod with a rod receiver in order to prevent the damper rod (piston rod) of the air cylinder from swinging and tilting. The structure of this rod receiver consists of a supporting curved portion that supports the lower surface and a biasing spring curved portion that supports the upper surface, and is provided in the cylinder and always supports the air cylinder and the damper rod coaxially. (Patent Document 1).
JP 09-88413 A

しかしながら、上記従来例では、ロッド受けはダンパーロッドを付勢バネ曲部により押圧支持しており抵抗が大きく、摩耗等を考えれば長期間の使用には不適切なものである。又、シリンダー内にロッド受けを設けることは補修、点検が面倒である欠点がある。   However, in the above-mentioned conventional example, the rod receiver presses and supports the damper rod by the urging spring curved portion, and the resistance is large, so that it is inappropriate for long-term use in consideration of wear and the like. In addition, the provision of the rod receiver in the cylinder has the disadvantage that it is troublesome to repair and inspect.

上記課題を解決するために、本願発明の自動閉鎖式引き戸用エアダンパーは、閉鎖方向の力を付与されている自動閉鎖式引き戸にエアシリンダーを設けてなる自動閉鎖式引き戸用エアダンパーにおいて、エアシリンダーのダンパーロッドをガイドするガイドブラケットをエアシリンダーを支持する支持台に固定してエアシリンダー前方に配置し、該ガイドブラケットは上下にローラーガイドを設け左右に樹脂製ガイドブロックを設けて構成されるものである。   In order to solve the above-mentioned problems, an air damper for an automatic closing type sliding door according to the present invention is an air damper for an automatic closing type sliding door in which an air cylinder is provided in an automatic closing type sliding door to which a force in the closing direction is applied. A guide bracket that guides the cylinder's damper rod is fixed to a support base that supports the air cylinder, and is placed in front of the air cylinder. The guide bracket is configured with roller guides on the top and bottom and resin guide blocks on the left and right. Is.

本願発明の自動閉鎖式引き戸用エアダンパーにおいては、ガイドブラケットが上下にローラーガイドを設けているために抵抗が小さいものである。即ち、ダンパーロッドはその荷重により上下方向に振れ、傾き易いものであるが、これを抑制するものとしてローラーガイドを上下に設けている。ローラーガイドは自由に回転するものであるためにダンパーロッドの進退に追随しながら上下方向の振れ、傾きを抵抗少なく抑制するものである。又、ガイドブラケットがエアシリンダーを支持する支持台に固定されエアシリンダー前方に配置されているためにエアシリンダーより独立しており、補修、点検が容易なものである。   In the air damper for a self-closing type sliding door according to the present invention, the guide bracket is provided with roller guides at the top and bottom, so that the resistance is small. That is, the damper rod swings in the vertical direction by the load and easily tilts, but roller guides are provided vertically to suppress this. Since the roller guide rotates freely, it is possible to suppress up and down vibration and inclination with little resistance while following the forward and backward movement of the damper rod. In addition, since the guide bracket is fixed to the support base that supports the air cylinder and is disposed in front of the air cylinder, it is independent of the air cylinder and is easy to repair and inspect.

図1、図2は一実施形態である自動閉鎖式引き戸用エアダンパーを示しており、図1は側面図、図2はガイドブラケットの説明図である。この図1に示す自動閉鎖式引き戸用エアダンパーでは、1はエアシリンダー、2はダンパーロッド、3はガイドブラケット、4は支持台である。   1 and 2 show an air damper for a self-closing sliding door according to an embodiment, FIG. 1 is a side view, and FIG. 2 is an explanatory view of a guide bracket. In the self-closing type sliding door air damper shown in FIG. 1, 1 is an air cylinder, 2 is a damper rod, 3 is a guide bracket, and 4 is a support.

引き戸(図示せず)はダンパーロッド2の先端部に位置しており、引き戸を閉めるときはダンパーロッド2をシリンダー1内に押し込む動作となり、シリンダー1内の空気を圧縮し引き戸を減速する。この場合、ダンパーロッド2が振れたり、傾いたりするとシリンダー1内の空気がダンパーロッド2の基端部より漏れ引き戸を減速する機能が損なわれる。ガイドブラケット3はダンパーロッド2が振れたり、傾いたりするのを防止するもので、図2に示す構造を有するものである。即ち、上下にローラーガイド5,5を配置し、左右に樹脂製ガイドブロック6,6を配置してなるものである。図2はダンパーロッド2がガイドブラケット3内を通る状態を示している。   The sliding door (not shown) is located at the tip of the damper rod 2, and when the sliding door is closed, the damper rod 2 is pushed into the cylinder 1, compressing the air in the cylinder 1 and decelerating the sliding door. In this case, when the damper rod 2 swings or tilts, the function of the air in the cylinder 1 decelerating the leakage sliding door from the base end portion of the damper rod 2 is impaired. The guide bracket 3 prevents the damper rod 2 from swinging or tilting, and has the structure shown in FIG. That is, roller guides 5 and 5 are arranged on the upper and lower sides, and resin guide blocks 6 and 6 are arranged on the left and right. FIG. 2 shows a state in which the damper rod 2 passes through the guide bracket 3.

ローラーガイド5,5は回転自在に保持されており、ダンパーロッド2が接触して進退するときは回転して追随しダンパーロッド2は大きな抵抗を受けないのである。即ち、ダンパーロッド2は上下の振れ、傾きをローラーガイド5,5により抑制されながら大きな抵抗は受けないのである。ローラーガイド5,5の材質はナイロン等のように摩耗に対して強い合成樹脂を選択するのが望ましい。樹脂製ガイドブロック6、6は左右に配置されダンパーロッド2の左右の振れを抑制する。この樹脂製ガイドブロック6,6の材質は特に限定されるものでなく、滑りの良い材質であれば良く、又特に形状を限定される必要もないものである。   The roller guides 5 and 5 are rotatably held. When the damper rod 2 contacts and advances and retreats, the roller guides 5 and 5 rotate to follow and the damper rod 2 does not receive a large resistance. That is, the damper rod 2 does not receive a large resistance while its vertical swing and inclination are suppressed by the roller guides 5 and 5. As the material of the roller guides 5 and 5, it is desirable to select a synthetic resin that is resistant to wear such as nylon. The resin guide blocks 6 and 6 are arranged on the left and right sides to suppress the left and right deflection of the damper rod 2. The material of the resin guide blocks 6 and 6 is not particularly limited, as long as it is a material with good sliding property, and the shape need not be particularly limited.

ガイドブラケット3はエアシリンダー1を支持する支持台4に固定され、エアシリンダー1前方に配置されている。ガイドブラケット3はそれを構成するローラーガイド5,5や樹脂製ガイドブロック6,6の補修や点検をする必要があるが、エアシリンダー1の前方に配置されているために独立しており、補修や点検が容易に行えるものである。   The guide bracket 3 is fixed to a support base 4 that supports the air cylinder 1 and is disposed in front of the air cylinder 1. The guide bracket 3 needs to be repaired and inspected for the roller guides 5 and 5 and the resin guide blocks 6 and 6 constituting the guide bracket 3, but is independent because it is arranged in front of the air cylinder 1, and is repaired. And can be easily inspected.
