Abstract

<P>PROBLEM TO BE SOLVED: To develop a swing door which can be kept open at any position without opening a hole on a floor or a wall, mounting a metal fitting or a magnet nor inserting a wedge-shaped stopper into a slot under the door. <P>SOLUTION: A rubber ball 1 made of highly resilient material for generating strong friction against a contacting object is stored in a space 2 provided inside of the swing door. The ball is managed to go up and down freely from outside with a shaft 4 connected through a string 3 or the like. By putting the ball 1 down at any position on the floor, the door can stop at the position despite an attempt to open/shut to either direction because the ball does not roll due to the strong friction generated between the ball and the floor as well as the ball and the inner side of the door and the resiliency of the ball to return to the original shape. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

Field of use to which the invention belongs

本発明は、ドア内部に格納したゴムボールを、床面に上げ下ろしするだけで、任意の位置に止め置くことが出来る様にした、住宅やオフィス等の内装に適した開き戸に関するものである。 The present invention relates to a hinged door suitable for interiors of houses, offices, and the like that can be stopped and placed at an arbitrary position simply by raising and lowering a rubber ball stored in a door.

従来、高価なドアクローザーを用いずに開き戸を開放しておくには、ドア中に内蔵した金属のピンを、床に開けた穴に差し込んだり、ドア外部に設けた金具を、床や壁に取り付けた金具やマグネットに連結する方法等が一般的で、ドア以外に床や壁にも何らかの加工を必要としていた。また、ドアを全開状態にしておくことは出来ても、任意の位置で止め置くことは難しかった。くさび型の小片をドア下と床のすき間に差し込む方法では、確かにドア及び床や壁に対する加工は不要だが、見た目のスマートさに欠ける上、すき間が小さいと装着が難しく、着脱時に手を汚したり、不使用時には邪魔になる等の欠点があった。なお、くさび型や重さを利用したドアストッパーも、設置した向きにしか機能しないので、ドアクローザーが付いていない開き戸を任意の位置止め置くことは出来なかった。 Conventionally, in order to keep the open door open without using an expensive door closer, insert a metal pin built in the door into a hole drilled in the floor or attach a bracket provided outside the door to the floor or wall A method of connecting to a metal fitting or a magnet is common, and some processing is required on the floor and wall in addition to the door. Moreover, although it was possible to keep the door fully open, it was difficult to stop the door at an arbitrary position. The method of inserting a wedge-shaped piece into the gap between the door and the floor certainly does not require processing on the door, floor, or wall, but it lacks the appearance of smartness and is difficult to install if the gap is small. There were drawbacks such as being in the way when not in use. In addition, the door stopper using a wedge shape or weight also works only in the direction in which it was installed, so it was not possible to place the hinged door without the door closer in any position.

Problems to be solved by the invention

本発明は、床や壁に対する加工が一切不要な上、簡単かつ経済的な方法で、任意の位置に止め置くことが出来る開き戸を、開発しようとするものである。 The present invention seeks to develop a hinged door that does not require any processing on a floor or a wall and can be stopped and placed at an arbitrary position by a simple and economical method.

Means for solving the problem

反発力に富み接したものとの間に大きな摩擦を生ずる材質よりなるゴムボール１を、ドア内のスペース２に格納する。ボール１にはヒモ３等を取り付け、他端をシャフト４に結ぶ等して、外部から自由に床面に上げ下ろしが出来るようにする。 A rubber ball 1 made of a material that generates a large friction with the object that is in contact with the repulsive force is stored in a space 2 in the door. A string 3 or the like is attached to the ball 1 and the other end is connected to a shaft 4 so that the ball 1 can be freely raised and lowered from the outside.

The invention's effect

本発明は以上のような構造であるから、任意の位置でシャフト４を操作して、ボール１が床面に触れるように下ろすと、ドアがどちらかの方向に開閉しようとした際に、ボール１は接するドア内の格納スペース２の側面より横方向の力を受けるが、その接点とボール１と床面との間に発生する摩擦力及びボール１が元の形状に戻ろうとする反発力とにより、ボール１は回転せずに床面に強く押しつけられる。よって、開き戸は動かずにその場に止め置かれる。なお、構造上、ドア下と床とのすき間が、ボールの直径の約半分以下の開き戸に対して有効であるが、床に油や水が付着していたり、厚い絨毯等が敷かれている場合は、ボールがスリップしてドアが止まらない場合がある。 Since the present invention has the structure as described above, if the shaft 4 is operated at an arbitrary position and the ball 1 is lowered so as to touch the floor surface, the ball will be opened when the door attempts to open or close in either direction. 1 receives a lateral force from the side surface of the storage space 2 in the door in contact, but a frictional force generated between the contact point and the ball 1 and the floor surface and a repulsive force that the ball 1 tries to return to its original shape, Thus, the ball 1 is strongly pressed against the floor without rotating. Therefore, the hinged door is stopped in place without moving. In addition, structurally, the gap between the bottom of the door and the floor is effective for hinged doors that are less than about half the diameter of the ball, but oil or water is attached to the floor or thick carpets are laid. In this case, the ball may slip and the door may not stop.

Other examples

ドアノブ５を連結しているシャフト４等に、ヒモ３やワイヤー等の先端を結んで、ボールを上げ下げ出来るようにしておけば、ドアのどちら側からでも腰をかがめずに操作出来る。
また、底面に開口部６を持つ堅牢なボックス７の前面に、上部の丁番８と下部のマグネット９等により開閉自在なフタ１０を設け、このフタに差し込んだシャフト１１の末端にボール１を取り付けて、フタ１０の開閉によりボール１の上げ下げが出来きる様にすると、ドアを任意の位置で留め置くための仕組みを一つのユニットとしてドア下部に組込むことが可能になり、ドアへの取り付けやボールに付着したゴミを取り除いたり交換すると言ったメンテナンスもしやすくなる。If the tip of string 3 or a wire is connected to the shaft 4 or the like connecting the door knob 5 so that the ball can be raised and lowered, it can be operated from either side of the door without bending down.
In addition, a lid 10 that can be opened and closed by an upper hinge 8 and a lower magnet 9 is provided on the front surface of a solid box 7 having an opening 6 on the bottom, and a ball 1 is placed on the end of a shaft 11 inserted into the lid. If it is attached and the ball 1 can be raised and lowered by opening and closing the lid 10, a mechanism for retaining the door at an arbitrary position can be incorporated into the lower part of the door as a single unit. Maintenance such as removing or replacing dust attached to the ball becomes easier.
