Abstract

[Problem] Conventionally, a door has been often fixed by using a wedge-shaped door stopper which has a shape or material having a large frictional force in a gap between the bottom of the door and the floor surface. However, in reality, a sufficient frictional force is not obtained between the floor surface and a door stopper lower surface, and thus there have been many disadvantageous cases where the door stopper moves together with the door when the door is closed (or opened). [Solution] Since the present invention places importance on sliding in the relation between a door and a door stopper, the door slides on the door stopper so as to increase downward pressure from the door stopper to the floor surface when the door is opened/closed, the door stopper does not move on the floor due to friction between the door stopper and the floor surface, and the door is easily stopped during the closing (or opening) motion of the door.

Description

摩擦の強い面と滑りの強い面を斜めに対面させて弾性的に固定して形成した楔形ドアストッパーA wedge-shaped door stopper formed by elastically fixing the frictional surface and the slippery surface diagonally facing each other
本発明は、ドアの底部と床面の隙間に差し込み、ドアを開いた状態に固定するためのドアストッパーに関する。 The present invention relates to a door stopper for being inserted into a gap between a bottom portion of a door and a floor surface and fixing the door in an open state.
従来からドアを開いた状態で固定するために、楔形のドアストッパーをドアの底部と床面の隙間に差し込み、固定する方法が多く用いられている。これは、ドアの底部と床面の隙間を楔により広げ、その反発力としての圧力を利用して、ドアの底部及び床面との摩擦力を高め、ドアストッパーそのものを固定することにより、その位置にドアを固定するものである。このため、ドアの底部と楔の上面、床面と楔の下面の摩擦抵抗がその機能に大きく作用し、これらの機能を効果的に果たすために特許文献１～１6にみられる材質、形状の改善が図られてきた。 Conventionally, in order to fix the door in the opened state, a method of inserting and fixing a wedge-shaped door stopper into the gap between the bottom of the door and the floor surface is often used. This is because the gap between the bottom of the door and the floor is widened with a wedge, the pressure as the repulsive force is used to increase the frictional force between the bottom of the door and the floor, and the door stopper itself is fixed. The door is fixed in position. For this reason, the frictional resistance of the bottom of the door and the upper surface of the wedge, the floor surface and the lower surface of the wedge greatly affects its function, and in order to effectively perform these functions, the materials and shapes found in Patent Documents 1 to 16 are used. Improvements have been made.

楔形のドアストッパーは、ドアの底部と床面の隙間に差し込んで使用するため、ドアの底部と床面との接触面において、摩擦力が大きい形状や材質を用いる。これでドアを固定する力は強くなるが、差し込む容易性が阻害される。また実際のドアの開閉動作時にはドアからドアストッパーへの水平方向の力が大きく、床との摩擦力よりも大きな力が加わる。 Since the wedge-shaped door stopper is used by being inserted into the gap between the bottom of the door and the floor, a shape or material having a large frictional force is used on the contact surface between the bottom of the door and the floor. This increases the force to fix the door, but hinders ease of insertion. Further, when the door is actually opened and closed, the horizontal force from the door to the door stopper is large, and a force larger than the frictional force with the floor is applied.
過去の楔形のドアストッパーは水平に動かす力を減らすために底面にさまざまの材質形状を工夫して移動を妨げるようにしている。また、材質を工夫して柔軟性を持たせて同じように水平方向の力を吸収している。 In the past, the wedge-shaped door stopper is designed to prevent movement by devising various material shapes on the bottom to reduce the horizontal movement force. In addition, the material is devised to give flexibility and absorb the horizontal force in the same way.
しかしながら、いずれもドアの水平移動の解決には至らず、ドアストッパーがドアの閉まる動きと一緒に動いてしまう。楔形の効果を得るまで差し込むことに苦労することが多く発生している。 However, none of these solutions solve the horizontal movement of the door, and the door stopper moves together with the door closing movement. Many times it has been difficult to insert until a wedge-shaped effect is obtained.
更に特許文献1にあるように、楔形ドアストッパーを上下二つに分割し中間にスライド面を形成したものもある。上側の移動を楔形の高さの増加による上下方向の圧力に変えて、床面との摩擦を強くして移動防止を図ったものであるが構造が複雑になるきらいがあった。 Further, as disclosed in Patent Document 1, there is also one in which a wedge-shaped door stopper is divided into an upper and lower part and a slide surface is formed in the middle. The upper movement is changed to a vertical pressure by increasing the height of the wedge shape, and the friction with the floor surface is strengthened to prevent the movement, but there is a tendency that the structure becomes complicated.
図１に示すように、楔形ドアストッパーの上面は、摺動性の高く柔軟な構造としドアが動いても楔に水平方向の力がかからないようにし、一方楔形ドアストッパー下面は溝や突起などあるいは粘着性の材質により摩擦が大きい構造にした。 As shown in FIG. 1, the upper surface of the wedge-shaped door stopper has a slidable and flexible structure so that no horizontal force is applied to the wedge even when the door moves, while the lower surface of the wedge-shaped door stopper has grooves, protrusions or the like. A structure with high friction due to the adhesive material.
ドアが移動すると楔形の上部をスライドすることになり、楔形にかかる水平方向の力は極めて少なくなり、一方ドアと喫形ドアストッパーの接触する位置は楔形のより高い位置に移動する。そこでドアは上方への力を受け、逆にドアストッパーは床面に押し下げられて摩擦力が増える。結果としてほとんどドアストッパーが移動することなくドアを止めることができる。 When the door moves, the upper part of the wedge shape is slid, and the horizontal force applied to the wedge shape is extremely reduced, while the position where the door contacts the draft door stopper moves to a higher position of the wedge shape. Therefore, the door receives an upward force, and conversely, the door stopper is pushed down to the floor surface and the frictional force increases. As a result, the door can be stopped with almost no movement of the door stopper.

ドアを開いた状態の任意の位置に止めることを、図２に示すようにドアと床面の間に差し込む型のドアストッパーにおいて、図３に示すように上下面の摩擦の違いを利用して作成した。 In order to stop the door at an arbitrary position in the opened state, as shown in FIG. 2, in the type of door stopper that is inserted between the door and the floor, the difference in friction between the upper and lower surfaces is utilized as shown in FIG. Created.
図３に示すように楔形の弾力のある部材の上部に摩擦の少ない滑らかで柔らかい面材を設けて、底面には柔らかい材料で鋸歯状の列を設けて摩擦を大きくした。 As shown in FIG. 3, a smooth and soft face material with little friction was provided on the top of a wedge-shaped elastic member, and a serrated row of soft material was provided on the bottom surface to increase the friction.
本ドアストッパーは家庭における居室あるいは公共・多人数で使用する居室、会議室、集会場、作業場党のおよそドアのある室で利用可能である。製作も複雑な工程なく行える。 This door stopper can be used in a room in a home or a public / multi-person room, a conference room, a meeting place, or a room with a door in a workshop party.
