Description

本発明は、開いた扉を所定の開放位置に解除可能に保持することが可能な戸当りに関するものである。 The present invention relates to a door stop capable of releasably holding an open door in a predetermined open position.

従来から扉を開いたときに所定の開放位置に保持するとともにそのまま扉を閉じることが可能な戸当りが知られており、扉を所定の開放位置に開くだけで保持されるとともに扉を閉じ方向に移動させるだけの簡単な操作で保持状態を解除することが可能なものとして例えば扉の下部に設置されるケース体に磁石を内蔵した戸当り本体と、床面に設置される台座に磁性体からなる係止プレートが基端部に配置した水平支軸により先端部が上下方向に揺動可能に配置された係止具とからなる戸当りが特開平１０−１１５１３９号公報、特開平１１−２８７０６２号公報などに提示されている。 Conventionally, a door stop that can be held in a predetermined open position when the door is opened and can be closed as it is is known. It is possible to release the holding state with a simple operation just by moving it to the door body, for example, a door-to-door body with a magnet built in the case body installed at the bottom of the door, and a magnetic body on the pedestal installed on the floor Japanese Patent Application Laid-Open No. 10-115139 and Japanese Patent Application Laid-Open No. 11-11 are made of a locking plate in which a locking plate having a distal end portion slidable in a vertical direction by a horizontal support shaft disposed at a base end portion of the locking plate. No. 287062 and the like.

しかしながら、前記公報に提示されている戸当りは磁石の吸着力により扉を床面に固定するものであり、例えば、強風の際などには扉を所定の開放位置に保持させていたいにも拘わらず保持状態が解除してしまうという問題があった。 However, the door stop proposed in the above publication is to fix the door to the floor surface by the attractive force of the magnet. For example, in the case of strong winds, the door should be held in a predetermined open position. There was a problem that the holding state was released.

そこで、例えば特開２００３−２０８４８号公報に提示されているように、扉の下部に設置されるケース体に磁石を内蔵した戸当り本体と、床面に設置される台座に磁性体からなる係止プレートが基端部に配置した水平支軸により先端部が上下方向に揺動可能に配置された係止具とからなる戸当りであって、前記係止具は先端部に前記水平支軸にほぼ平行な段状の被係止部が形成されており、前記戸当り本体は前記磁石が前記係止プレートを磁気吸着力で斜めに起立させるための傾斜面を有するとともに、前記斜めに起立させた被係止体の先端部が扉の移動に伴って前記係止プレートに形成した前記被係止部を係止凹部に嵌挿係止する戸当りが提示されている。 Therefore, for example, as disclosed in Japanese Patent Application Laid-Open No. 2003-20848, a door-contact main body in which a magnet is built in a case body installed at the lower part of a door, and a base made of a magnetic material on a pedestal installed on a floor surface. The stopper plate is a door stop composed of a locking member whose tip end portion is disposed so as to be swingable in the vertical direction by a horizontal support shaft disposed at the base end portion, and the locking tool is disposed at the tip end portion of the horizontal support shaft. The door-contact main body has an inclined surface for allowing the magnet to stand obliquely with a magnetic attraction force, and the door-standing main body stands up diagonally. The door stop which the front-end | tip part of the made to-be-latched body fits and latches the to-be-latched part formed in the said latching plate in the latching recessed part with the movement of a door is shown.

この従来の戸当りは、不使用時には係止具が床面から突出することがなく、単に磁力により吸着させるだけのものと異なりプレートの先端に形成した段状部が戸当り本体に設置された係止部の係止凹部に嵌挿係止されるとともにこの係止状態がばねによる付勢力により保持されるので扉の外側から風などのような外力が作用しても扉は開状態を保持することができるという利点を有している。 In this conventional door stop, the locking member does not protrude from the floor when not in use, and unlike the case of simply adsorbing by magnetic force, a stepped portion formed at the tip of the plate is installed in the door stop body. The door is kept in the open state even when an external force such as wind is applied from the outside of the door because the locking state is retained by the urging force of the spring. Has the advantage of being able to.

しかしながら、この従来の戸当りは、前記段状の被係止部と係止凹部との係合が被係止部を係止凹部を有する鈎形の係止部により押圧することにより保持するものであり、保持力が十分でないという問題がある。 However, in this conventional door stop, the engagement between the stepped locked portion and the locking recess is held by pressing the locked portion with a hook-shaped locking portion having a locking recess. There is a problem that the holding power is not sufficient.

図１乃至図４は本発明の好ましい実施の形態を示すものであり、戸当り１は、例えば開き戸における扉２の引き寄せ側の側面２１における下部に設置される戸当り本体３と床面４に設置される係止具５から構成される。 1 to 4 show a preferred embodiment of the present invention. A door stop 1 is formed by, for example, a door stop main body 3 and a floor surface 4 installed at a lower portion of a side surface 21 on a pulling side of a door 2 in a hinged door. It is comprised from the securing tool 5 installed.

そして、戸当り本体３は例えば適宜硬質の合成樹脂や金属などにより成型されたケース体３１に磁石３２と中央部において配置された支持軸３５により回動可能に支持された鈎形の係止部材３４を有しており、係止具５は、台座５１に磁性体である金属帯を加工してなる係止プレート５２が基端部に配置した水平支軸５３により先端部が上下方向に揺動可能に配置された構成を有し、前記係止プレート５２の先端部に少なくとも前記水平支軸５３にほぼ平行な開口縁５４を有する透窓からなる被係止部５５が形成されている。 The door stop main body 3 is, for example, a bowl-shaped locking member rotatably supported on a case body 31 formed of, for example, a hard synthetic resin or metal by a magnet 32 and a support shaft 35 disposed in the central portion. 34. The locking member 5 has a distal end portion which is vertically moved by a horizontal support shaft 53 which is disposed at a base end portion of a locking plate 52 formed by processing a metal band as a magnetic body on the base 51. A locked portion 55 made of a transparent window having an opening edge 54 at least substantially parallel to the horizontal support shaft 53 is formed at the distal end portion of the locking plate 52.

また、前記戸当り本体３は、前記磁石３２の底面が前記係止プレート５２を磁気吸着力で斜めに起立させるための傾斜面３２１を有するとともに、先端に先端面がほぼ方形で前記被係止部の開口縁５４に沿って嵌挿入可能な長さを有す係止突起３３が形成された鈎形の係止部材３４が支持軸３５により回動可能に支持されており、この係止部材３４の基端側にはコイルばね３６により先端方向に付勢されて前記係止突起３３が磁石３２の傾斜面３２１に押圧状態にある。 The door stop main body 3 has an inclined surface 321 for allowing the bottom surface of the magnet 32 to stand up obliquely by the magnetic attraction force of the locking plate 52, and the tip surface is substantially square at the tip. A hook-shaped locking member 34 formed with a locking projection 33 having a length that can be inserted and inserted along the opening edge 54 of the portion is rotatably supported by a support shaft 35. The locking protrusion 33 is pressed against the inclined surface 321 of the magnet 32 by being biased in the distal direction by a coil spring 36 on the proximal end side of 34.

このような構成を有する本実施の形態は、図４（ａ）に示すように、開き戸における扉２の引き寄せ側の側面２１における下部に戸当り本体３を取り付けるとともに床面４に係止具５が取り付けられる。 As shown in FIG. 4A, the present embodiment having such a configuration attaches the door-holding body 3 to the lower part of the side surface 21 on the pulling side of the door 2 in the hinged door, and locks the fixture 5 on the floor surface 4. Is attached.

そして、扉が開いたときに、図４（ｂ）に示すように、前記磁石３２が前記係止プレート５２を磁気吸着力で傾斜面に３２１に吸着させて斜めに起立させる。 When the door is opened, as shown in FIG. 4 (b), the magnet 32 causes the locking plate 52 to be attracted to the inclined surface 321 by a magnetic attraction force, and stands up obliquely.

そして、更に、扉が開くと、図４（ｃ）に示すように、前記斜めに起立させた係止プレート５２の先端部が扉の移動に伴って係止プレート５２の先端が前記コイルばね３６の付勢力に抗して係止突起３３と磁石３２の傾斜面３２１との間に差し込まれ、係止プレート５２の被係止部５５に係止突起３３が嵌挿係止して扉２が所定の開位置で保持される。 Further, when the door is opened, as shown in FIG. 4C, the distal end portion of the locking plate 52 raised obliquely moves the distal end of the locking plate 52 to the coil spring 36 as the door moves. The latch 2 is inserted between the latch projection 33 and the inclined surface 321 of the magnet 32 against the urging force of the magnet 32. It is held in a predetermined open position.

このとき、本実施の形態では、係止突起３３が係止プレート５２に形成した少なくとも直線状の開口縁を有する透窓から被係止部５５に嵌挿係止されるので確実に扉２か所定の開位置に保持される。尚、この保持力は、前記コイルばね３６の付勢力により調整可能であり、扉や使用する環境に応じて適宜選択すればよい。 At this time, in the present embodiment, the locking projection 33 is fitted and locked to the locked portion 55 from the through window having at least a linear opening edge formed on the locking plate 52, so that the door 2 is securely connected. It is held in a predetermined open position. This holding force can be adjusted by the biasing force of the coil spring 36, and may be appropriately selected according to the door and the environment in which it is used.

そして、扉２の開状態から前記磁石３２の磁気吸着力と前記コイルばね３６の付勢力の和よりも大きな閉じ力が前記扉２に作用したときに係止プレート５２が前記付勢力に抗して前記係止突起３３から抜脱して前記被係止部５５との係合が解除され前記戸当り本体３と係止具５との係合が解除されて扉２が閉成する。 When the closing force larger than the sum of the magnetic attraction force of the magnet 32 and the urging force of the coil spring 36 is applied to the door 2 from the opened state of the door 2, the locking plate 52 resists the urging force. As a result, the engagement with the locked portion 55 is released and the engagement between the door stop main body 3 and the locking tool 5 is released, and the door 2 is closed.

また、本実施の形態では、係止プレート５２の先端を巻き込んで段部５２１を形成したので、係止プレート５２の先端強度が増しており、大気優勢に優れているが、図５に示すように先端の段部５２１を前記被係止部５５の部分を除いて形成することにより、係止プレート５２の先端が係止突起３３と磁石３２の傾斜面３２１に差し込み易くなり円滑な作動を確保することができる。 Further, in this embodiment, since the step 521 is formed by winding the tip of the locking plate 52, the strength of the tip of the locking plate 52 is increased and excellent in the atmosphere, but as shown in FIG. By forming the stepped portion 521 at the tip excluding the portion to be locked 55, the tip of the locking plate 52 can be easily inserted into the locking projection 33 and the inclined surface 321 of the magnet 32 to ensure smooth operation. can do.
