Description

【0001】
【発明の属する技術分野】
本発明は戸当りに関する。さらに詳しくは、組立てを容易にして、作業性を向上させることができる戸当りに関する。
【0002】
【従来の技術】
従来より、図5〜6に示すように、戸50の開閉により戸50またはノブ51が壁または戸50周辺の家具やキャビネット52などに衝突し、これらに損傷が生じるのを防ぐために、戸当り53が戸50の付近の静止体である床54に設けられている。
【0003】
かかる戸当り53としては、図7に示されるように床54に固着されるねじ付台座60に螺着される基部55および該基部55の上部に固着される緩衝体56とからなる戸当り本体53aと、U字状の止め金具57となるものがある。そして、この戸当り53では、戸50を開放状態にしておくために、前記基部55内に差し込まれているU字状の止め金具57を引き抜き、戸50の側面に設けられた鉤付き座金58の鉤部59に係止するようにしている。
【0004】
【発明が解決しようとする課題】
前記戸当り53の組付けは、図7に示されるように回り止めおよび仮止めのための針部62を床54に打ち込んだのち、固定ねじ63を予め中央部に形成される中央孔に挿通してねじ付台座60を床54に固定し、ついで戸当り本体53aの雌ねじ部55aを前記ねじ付台座60の雄ねじ部61にねじ込んで行なわれる。
【0005】
現在、前記ねじ付台座60は、棒材をねじ切りしつつ所定長さで切断することにより作製されている。コストダウンを図るために、このねじ付台座60を鋳造により作製することも考えられるが、外周の雄ねじ部61は鋳造時に分割型を合わせて形成するため、雄ねじ部61における合せ面(型分割面)64の周辺部位に、バリや段違い部などが発生しやすくなる。そうすると、戸当り本体53aとのねじ嵌合時に前記ねじ付台座60のバリなどが戸当り本体53aの雌ねじ部55aに干渉して戸当り本体60をねじ込むことができない場合が多くなるため、鋳造後に、バリ取りやねじ部の歯付けなどの作業を行なう必要があり、かえってコストがアップしてしますという問題がある。
【0006】
本発明は、叙上の事情に鑑み、鋳造後の作業が不要であり、コストダウンを図ることができる戸当りを提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明の戸当りは、内周に雌ねじ部が形成される戸当り本体を固定する際に、外周に雄ねじ部が形成されるねじ付台座を用いる戸当りであって、前記ねじ付台座が、分割型を合わせて、雄ねじ部が同時に形成される鋳物であり、該雄ねじ部のうち、鋳造時の合せ面周辺のねじ部に平坦面が形成されてなることを特徴としている。
【0008】
【発明の実施の形態】
以下、添付図面に基づいて本発明の戸当りを説明する。
【0009】
図1は本発明の戸当りの一実施の形態を示す分解図、図2は図1におけるねじ付台座の正面図、図3は図1におけるねじ付台座の平面図、図4は本発明の他の実施の形態にかかわる戸当りをドアに取り付けた状態を示す説明図である。
【0010】
図1〜3に示すように、本発明の一実施の形態にかかわる戸当りは、戸当り本体1と、該戸当り本体1を螺着させるねじ付台座2とから構成され、該ねじ付台座2は固定ねじ3により床、壁または戸などに固着される。
【0011】
前記戸当り本体1は、内周に雌ねじ部4が形成される基部5と、該基部5の上部に固着される緩衝体6とからなり、本実施の形態では、該緩衝体6の外周突起部7から内側の凹部に磁石部8が埋設されている。該磁石部8としては、一対の磁性体8aに挟持される、たとえばフェライト磁石または稀土類磁石などの永久磁石8bを用いることができる。該磁性体8aの先端面は永久磁石8bよりも突出しているため、戸から永久磁石8bに掛かる衝突を和らげるとともに、磁力線を前記先端面から集中して放射させることにより、戸の表面に設けられた磁性体からなる受体に対する吸着力を強くすることができる。また、この磁石部8を前記凹部において前後方向および上下方向に移動できる構造にすることにより、戸を安定して全開状態に保持することができ、戸が外力を受けて振動するなどの不具合を低減させることができる。なお、この磁石部8を省略して、図6に示されるように止め金具と鉤部によって、戸を開状態に保つようにしてもよい。
【0012】
前記ねじ付台座2は、たとえば分割型、すなわち半円形の凹部表面に半周のねじ切り加工された鋳型を合わせて、周方向に雄ねじ部9が同時に形成(鋳造)される鋳物、すなわち鋳造品である。また下端面には回り止めおよび仮止めのための針部10も同時に鋳造されている。そして、前記雄ねじ部9のうち、鋳造時の合せ面11周辺のねじ部9aには平坦面12がそれぞれ形成されている。この平坦面12を形成することにより、鋳造後に合わせ面11に多少のバリが発生したとしても、このバリは雄ねじ部9のみぞよりも半径方向内側に位置するため、前雌ねじ部4と雄ねじ部9との螺合が阻害されることはなく、前記戸当り本体1をねじ付台座2に容易に嵌め合わせることができる。また前記ねじ付台座2の中央部には、前記固定ねじ3を差し込むための貫通孔13が切削されている。
【0013】
本実施の形態における戸当りの床への組付けは、まず前記ねじ付台座2の針部10を床に打ち込んだのち、固定ねじ3をねじ付台座2の貫通孔13に挿通してねじ付台座2を床に固定する。この固定ねじ3によるねじ止めのときに前記針部10によりねじ付台座2が防止されて、確実に固定することができる。ついで戸当り本体1の雌ねじ部4を前記ねじ付台座2の雄ねじ部9にねじ込んで行なわれる。このとき、前述したように、前記戸当り本体1とねじ付台座2のねじ嵌合が容易となり、組立て作業の効率化を図ることができる。
【0014】
本発明は、本実施の形態のように床に取り付ける戸当りに限定されるものではない。たとえば戸に取り付ける戸当りとする場合には、図4に示されるように長尺の緩衝体の先端部に埋め込まれた磁石部22を有する戸当り本体21と、該本体21の基部に螺着される鋳造品のねじ付台座25とからなる戸当りを用いることができる。またこのねじ付台座25についても、雄ねじ部における合せ面周辺のねじ部には平坦面23がそれぞれ形成されているとともに、下端面には回り止めおよび仮止めのための針部24が同時に鋳造されている。
【0015】
かかる戸当りの戸Aへの組付けは、まずねじ付台座25の針部24を戸Aに打ち込んだのち、固定ねじ26により固定する。ついで該ねじ付台座25に戸当り本体21をねじ込んで行われる。なお、この戸当りの組付けとともに、壁Bには、該戸当りの所定の高さの位置と同じ位置に、前記磁石部22との吸着力により戸当りを開状態に保持させるための金属製座板27が2本の固定ねじ28により固定される。なお、磁石部を壁に取り付ける金属製座板に設け、緩衝体の先端部に金属板を埋め込むようにしてもよい。
【0016】
前記実施の形態と同様に、前記戸当り本体21とねじ付台座24のねじ嵌合は容易であり、組立て作業の効率化を図ることができる。
【0017】
なお、本発明における戸当りは、床または戸に取りつける場合に限定されるものではなく、壁Bに取り付けることもできる。
【0018】
【発明の効果】
以上説明したとおり、本発明によれば、鋳造後の作業が不要であり、コストダウンを図ることができる。

[0002]
[Prior art]
Conventionally, as shown in FIGS. 5 to 6, in order to prevent the door 50 or the knob 51 from colliding with the wall or furniture around the door 50 or the cabinet 52 due to opening and closing of the door 50, 53 is provided on a floor 54 which is a stationary body near the door 50.
[0003]
As the door stop 53, as shown in FIG. 7, a door stop body including a base 55 screwed to a screw base 60 fixed to the floor 54 and a buffer body 56 fixed to the upper portion of the base 55. 53 a and a U-shaped stopper 57. In this door stop 53, in order to keep the door 50 in an open state, the U-shaped stopper 57 inserted in the base portion 55 is pulled out, and a hooked washer 58 provided on the side surface of the door 50. It is made to latch on the collar part 59.
[0004]
[Problems to be solved by the invention]
As shown in FIG. 7, the door stop 53 is assembled by driving a needle portion 62 for detent and temporary fixing into the floor 54 and then inserting a fixing screw 63 into a central hole formed in the central portion in advance. Then, the threaded pedestal 60 is fixed to the floor 54, and then the female threaded portion 55a of the door stop main body 53a is screwed into the male threaded portion 61 of the threaded pedestal 60.
[0005]
Currently, the threaded pedestal 60 is manufactured by cutting a rod material at a predetermined length while threading. In order to reduce the cost, it is conceivable to manufacture the threaded base 60 by casting. However, since the outer male threaded portion 61 is formed by combining the split molds at the time of casting, the mating surface (die splitting surface) of the male threaded portion 61 is formed. ) Burrs, uneven parts, etc. are likely to occur around 64. Then, when the screw is fitted to the door stop main body 53a, the burrs of the threaded base 60 may interfere with the female thread portion 55a of the door stop main body 53a and the door stop main body 60 cannot be screwed in. However, there is a problem that it is necessary to carry out operations such as deburring and toothing of the screw portion, which increases the cost.
[0006]
In view of the above circumstances, an object of the present invention is to provide a door stop that requires no work after casting and can reduce costs.
[0007]
[Means for Solving the Problems]
The door stop of the present invention is a door stop using a threaded base in which a male screw part is formed on the outer periphery when fixing the door main body in which the female screw part is formed on the inner periphery. It is a casting in which a male thread part is formed at the same time by combining the split molds, and a flat surface is formed in a thread part around the mating surface during casting among the male thread parts.
