Description

本発明は、所定の開き位置で回動ドアを停止保持させるドアストッパーに関するものである。 The present invention relates to a door stopper that stops and holds a rotating door at a predetermined opening position.

従来、回動ドアを停止保持させるドアストッパーとして、床面にピン体を突出させてこのピン体にドア側に保持させたフックを着脱自在に係合させたり（特許文献１参照）、又はピン体とドアとの接触面に磁石と被吸着体を取り付けて相互に吸着させるようにした（特許文献２参照）方式のものや、或いは特許文献３に示すように、回動ドアを開放したときに床面に埋め込んだ回動舌片が、回動ドアに固定したボデイの磁石に吸着されて傾斜姿勢に立ち上がり、ドアを停止させる方式のものが知られている。
特開平１０−２３８１９３号公報特開平１０−１５９４２５号公報特開２０００−８０８５４号公報 Conventionally, as a door stopper for stopping and holding a rotating door, a pin body protrudes from the floor surface and a hook held on the door side by this pin body is detachably engaged (see Patent Document 1) or a pin. When the magnet and the object to be adsorbed are attached to the contact surface between the body and the door so that they are attracted to each other (see Patent Document 2), or when the rotating door is opened as shown in Patent Document 3 A rotating tongue piece embedded in the floor is attracted to a body magnet fixed to the rotating door, rises to an inclined posture, and stops the door.

しかし、特許文献１並びに２の方式では、ピン体が常に床面から突出した状態となっているので、掃除や歩行の妨げになると共に、外観上見劣りがすると行った欠点がある。また、特許文献３の方式は、磁石と回動舌片との吸着力で回動ドアの開き姿勢を保持する構造となっているから、回動ドアの保持力は磁石の吸着力のみに依存している。しかし磁石の吸着力には限界があり、振動等の軽い力で自然に磁石との吸着が外れて回動ドアが自由回動することがあるとともに、ボデイの取付位置が所定の位置より少しでも上下にずれると、回動舌片の立ち上がり角度とボデイの傾斜吸着面の角度が合わなくなって両者間に隙間が生じ、磁石の吸着力が著しく低下するといった欠点があった。 However, in the methods of Patent Documents 1 and 2, the pin body is always in a state of protruding from the floor surface. Therefore, there are drawbacks in that cleaning and walking are hindered and appearance is inferior. Moreover, since the system of Patent Document 3 has a structure in which the opening posture of the rotating door is held by the attractive force between the magnet and the rotating tongue, the holding force of the rotating door depends only on the attractive force of the magnet. is doing. However, there is a limit to the magnet's attractive force, and the light may be easily removed from the magnet by vibration or other forces, causing the rotating door to rotate freely, and the body mounting position may be slightly less than the specified position. When shifted up and down, the rising angle of the rotating tongue piece and the angle of the inclined attracting surface of the body are not matched, and there is a defect that a gap is created between the two and the attracting force of the magnet is significantly reduced.

そこで本発明は、上記のような従来欠点を解消すると共に、製作性に優れたドアストッパーを提供することを主たる目的とするものである。 Accordingly, the present invention mainly aims to provide a door stopper that eliminates the above-described conventional drawbacks and is excellent in manufacturability.

上記の課題を解決するために本発明では次のような技術的手段を講じた。即ち、本発明にかかるドアストッパーは、上端が開口した筒状ボディと、先端部が筒状ボディの上端開口部から所定ストロークだけ出没できるように筒状ボディ内に収納された軸部材と、該軸部材を常時突出方向に付勢するスプリングとからなり、軸部材の外周面に放射方向に突出したピンが設けられ且つ上端面には回動操作溝が設けられており、前記筒状ボディの内周面には前記ピンがスライド自在に嵌合するガイド溝が設けられ、該ガイド溝は上下方向に延びる垂直溝と、この垂直溝の下端に連なって側方に設けられた係合溝と、ピンを垂直溝から係合溝にガイドする傾斜ガイド面とから形成されており、更に前記筒状ボディが、垂直溝の下端を分岐として分割成形された上部ボディと下部ボディの結合体により構成されている構造とした。 In order to solve the above problems, the present invention takes the following technical means. That is, the door stopper according to the present invention includes a cylindrical body having an upper end opened, a shaft member housed in the cylindrical body so that a tip end portion thereof can be projected and retracted from the upper end opening of the cylindrical body, A spring that constantly urges the shaft member in the protruding direction, a pin protruding radially is provided on the outer peripheral surface of the shaft member, and a rotation operation groove is provided on the upper end surface; The inner peripheral surface is provided with a guide groove into which the pin is slidably fitted. The guide groove has a vertical groove extending in the vertical direction, and an engagement groove provided on the side of the vertical groove. And an inclined guide surface that guides the pin from the vertical groove to the engagement groove, and the cylindrical body is composed of a combined body of the upper body and the lower body that is divided and formed with the lower end of the vertical groove as a branch. With the structure being .

上記のドアストッパーは、その筒状ボディの上端面が床面と略面一となるように筒状ボディを床面の所定位置に埋め込んで使用される。 The door stopper is used by embedding the cylindrical body in a predetermined position on the floor surface so that the upper end surface of the cylindrical body is substantially flush with the floor surface.

本発明によれば、ドアストッパーとなる軸部材を筒状ボディに押し込むだけで軸部材の没入姿勢を保持することができて床面を平らな面に保つことができるとともに、必要に応じて回動操作溝を介して軸部材を回動させることにより軸部材を突出させて回転ドアの開き姿勢を確実に保持することができることができる。また、ガイド溝が外部に突出する軸部材ではなくて、筒状ボディの内周面に形成されているので、ガイド溝に埃が溜まって軸部材のスライドを阻害する事態の発生を未然に防止することができる。加えて、筒状ボディが、垂直溝の下端を分岐として分割成形された上部ボディと下部ボディの結合体により構成されているので、筒状ボディ内周面にガイド溝が形成されているにもかかわらず、簡単な樹脂成形金型で多数取り成形が可能となり、低コストで製作することが可能となる、といった種々の効果がある。 According to the present invention, the shaft member can be kept in the immersive posture simply by pushing the shaft member serving as the door stopper into the cylindrical body, the floor surface can be kept flat, and can be rotated as necessary. By rotating the shaft member through the dynamic operation groove, the shaft member can be protruded and the opening posture of the rotary door can be reliably held. Also, since the guide groove is formed on the inner peripheral surface of the cylindrical body, not on the shaft member that protrudes to the outside, it is possible to prevent the occurrence of a situation where dust accumulates in the guide groove and obstructs the sliding of the shaft member. can do. In addition, since the cylindrical body is composed of a combined body of the upper body and the lower body that is divided and formed with the lower end of the vertical groove as a branch, a guide groove is formed on the inner peripheral surface of the cylindrical body. Regardless, there are various effects such that a large number of molds can be formed with a simple resin molding die, and it can be manufactured at low cost.

以下、本発明の詳細を図面に示した実施例に基づいて説明する。
このドアストッパーは、上端が開口した合成樹脂製の筒状ボディ１と、先端部が筒状ボディ１の上端開口部から所定ストロークだけ出没できるように筒状ボディ１に収納された合成樹脂製の軸部材２と、該軸部材２を常時突出方向に付勢するスプリング３とを備えている。 Hereinafter, details of the present invention will be described based on embodiments shown in the drawings.
The door stopper is made of a synthetic resin cylindrical body 1 having an open upper end and a synthetic resin housed in the cylindrical body 1 so that a tip portion can protrude and retract from the upper end opening of the cylindrical body 1 by a predetermined stroke. A shaft member 2 and a spring 3 that constantly urges the shaft member 2 in the protruding direction are provided.

前記軸部材２の外周面に放射方向に突出したピン４が設けられ且つ上端面には指爪やコイン或いはドライバー等の工具が係合して軸部材を回動させるための回動操作溝５が設けられている。また、前記筒状ボディ１の内周面には、前記ピン４がスライド自在に嵌合するガイド溝６が設けられている。 A pin 4 projecting radially is provided on the outer peripheral surface of the shaft member 2, and a rotation operation groove 5 for rotating a shaft member by engaging a fingernail, a coin or a tool such as a screwdriver on the upper end surface. Is provided. In addition, a guide groove 6 in which the pin 4 is slidably fitted is provided on the inner peripheral surface of the cylindrical body 1.

このガイド溝６は、図３に示すように、上下方向に延びる垂直溝６ａと、この垂直溝６ａの下端に連なって側方に設けられた係合溝６ｂと、ピン４を垂直溝６ａから係合溝６ｂにガイドする傾斜ガイド面６ｃとから形成されている。また、筒状ボディ１の下端は底板により閉ざされている。 As shown in FIG. 3, the guide groove 6 includes a vertical groove 6a extending in the up and down direction, an engaging groove 6b provided on the side of the vertical groove 6a, and a pin 4 extending from the vertical groove 6a. An inclined guide surface 6c that guides the engaging groove 6b is formed. The lower end of the cylindrical body 1 is closed by a bottom plate.

更に、前記筒状ボディ１が、垂直溝６ａの下端を分岐として分割成形された上部ボディ１ａと下部ボディ１ｂの結合体により構成されている。両者の結合は接着材が好ましいがネジや嵌合等の手段でも可能である。上部ボディ１ａと下部ボディ１ｂの結合前の形態では、垂直溝６ａの下端が上部ボディ１ａの下端面に開口された形態となっており、係合溝６ｂの上端が下部ボディ１ｂの上端面に開口した形態で成形されている。従って、上部ボディ１ａ並びに下部ボディ１ｂは、無理抜き機構や複雑な機構を組み込むことなく、簡潔な２分割の樹脂成形金型により簡単に成形することができる。 Further, the cylindrical body 1 is constituted by a combined body of an upper body 1a and a lower body 1b that are divided and formed with the lower end of the vertical groove 6a as a branch. The bonding of both is preferably an adhesive, but can also be achieved by means such as screws or fittings. In the form before the upper body 1a and the lower body 1b are joined, the lower end of the vertical groove 6a is opened at the lower end surface of the upper body 1a, and the upper end of the engaging groove 6b is the upper end surface of the lower body 1b. Molded in an open form. Therefore, the upper body 1a and the lower body 1b can be easily molded by a simple two-part resin molding die without incorporating a forced punching mechanism or a complicated mechanism.

上記係合溝６ａの上端面６ｄは実質的に上部ボディ１ａの下端面で形成され、この部分にピン４が係合することにより、図１に示す軸部材２の没入姿勢が保持されるように形成されている。 The upper end surface 6d of the engaging groove 6a is substantially formed by the lower end surface of the upper body 1a, and the pin 4 is engaged with this portion, so that the immersion posture of the shaft member 2 shown in FIG. 1 is maintained. Is formed.

このドアストッパーを使用するに当たっては、図４並びに図５に示すように回動ドアーＡを設置した床面Ｂの所定の位置に、埋め込んで使用する。
ストッパーを必要としないときは図４及び図５の軸部材突出姿勢から、軸部材２をスプリング３に抗して手や足先で単に押し込むだけでよい。軸部材２を押し込むと軸部材２のピン４が、図６の(イ)の位置から垂直溝６ａを下降して傾斜ガイド面６ｃに当たり、このガイド面６ｃ沿ってスライドして軸部材２を回動させながら図６の(ロ)に示すように係合溝６ｂに移行する。そこで押し込み力がなくなるとスプリング３により少し押し上げられて図６の(ハ)に示すように係合溝６ｂの上端面６ｄに係合し、軸部材２の没入姿勢が保持される。
また、回動ドアＡを、ドアストッパーを通り越した位置で開放姿勢を保持する場合は、軸部材２の回動操作溝５に指爪やコイン或いは適当な工具を係合させて軸部材２を所定の方向に少し回動すればよい。軸部材２を回動させるとピン４が係合溝６ｂから垂直溝６ａに移行し、スプリング３により軸部材２が押し上げられて図２、図４並びに図５の突出姿勢になる。これにより回動ドアＡの開放姿勢を確実に保持できる。尚、軸部材２の突出量は回動ドアＡの下端が接当するに充分な長さとすることは勿論である。 When this door stopper is used, it is used by being embedded in a predetermined position on the floor B where the rotating door A is installed as shown in FIGS.
When the stopper is not required, the shaft member 2 may be simply pushed by the hand or the tip of the shaft against the spring 3 from the protruding posture of the shaft member shown in FIGS. When the shaft member 2 is pushed in, the pin 4 of the shaft member 2 descends from the vertical groove 6a from the position (a) in FIG. 6 and hits the inclined guide surface 6c, and slides along the guide surface 6c to rotate the shaft member 2. While being moved, as shown in FIG. Therefore, when the pushing force is lost, the spring 3 is slightly pushed up and engaged with the upper end surface 6d of the engaging groove 6b as shown in FIG.
Further, when the rotating door A is held in an open position at a position past the door stopper, a fingernail, a coin, or an appropriate tool is engaged with the rotating operation groove 5 of the shaft member 2 so that the shaft member 2 is moved. What is necessary is just to turn a little in a predetermined direction. When the shaft member 2 is rotated, the pin 4 shifts from the engaging groove 6b to the vertical groove 6a, and the shaft member 2 is pushed up by the spring 3 so that the protruding postures shown in FIGS. Thereby, the open attitude | position of the rotation door A can be hold | maintained reliably. Of course, the protruding amount of the shaft member 2 is set to a length sufficient for the lower end of the rotary door A to contact.
