Abstract

PROBLEM TO BE SOLVED: To provide a gravity hinge with a built-in hydraulic damper, which dramatically suppresses an impact noise when a door is closed by self-weight.SOLUTION: A small-sized linear stroke type hydraulic damper 5 is vertically mounted on an upper location within a cylinder part 31 in an upper part 3 of a hinge. Immediately before a door 200 is completely lowered while being rotated by self-weight in a closing direction, a tip 5a of the hydraulic damper 5 abuts on a tip of a shaft 4 to make the tip 5a recede. Thus, the gravity hinge with the damper can reduce a speed until the completion of closing of the door 200.SELECTED DRAWING: Figure 3

Description

本発明は、扉が閉じる際の衝撃を抑える直線ストローク型の油圧ダンパをヒンジ上部の筒部内又はヒンジ下部の筒部内に縦方向に配設したダンパ付きグレビティヒンジに関する。   The present invention relates to a damper-attached gravity hinge in which a linear stroke type hydraulic damper that suppresses an impact at the time of closing a door is disposed in a vertical direction in a cylinder part at an upper part of a hinge or a cylinder part at a lower part of the hinge.

特許文献1に、扉の自重により閉じる蝶番(グレビティヒンジ)が開示されている。この種の蝶番(グレビティヒンジ)を用いると、扉は自重で下方移動しながら閉じ方向に回転する。この閉じ方向の回転速度は、扉が閉じ終えるまで低下しないため、扉は閉じ終えるときに大きな衝撃音を発生する。この不具合を解消させるため、従来では扉枠にダンパを取り付けて、扉が閉じる直前に扉の閉じる速度を低下させていた。   Patent Document 1 discloses a hinge (gravity hinge) that closes due to the weight of the door. When this type of hinge (gravitational hinge) is used, the door rotates in the closing direction while moving downward under its own weight. Since the rotation speed in the closing direction does not decrease until the door is closed, a loud impact sound is generated when the door is closed. In order to solve this problem, conventionally, a damper is attached to the door frame, and the closing speed of the door is reduced immediately before the door is closed.

Then, the convex cam member can be set as a holding member, and the direction of the shaft rotation direction can be set within a range of 90 ° to 120 °, for example. As a result, the door opening / closing range can also be set to a range of 90 ° to 120 °, for example.

請求項3に係るダンパ付きグレビティヒンジによれば、凸形カム部材と保持部材とによる軸回転方向の係合位置の微調整が、凸形カム部材の抜き挿しという簡単な操作で行える。この結果、扉が閉じた場合で扉に閉じ方向の力を残し続けることができる。   According to the gravity hinge with a damper according to the third aspect, the engagement position in the axial rotation direction by the convex cam member and the holding member can be finely adjusted by a simple operation of inserting / removing the convex cam member. As a result, when the door is closed, a force in the closing direction can remain in the door.

扉200が自重により閉じる方向の移動は、扉200が閉じ終えるまで続き、ヒンジ上部3全体が傾斜カム面26aに沿った180°の位置まで、回転をしながら下方移動する。ヒンジ上部3全体が下方移動し始めると、油圧ダンパ5の先端部5aとシャフト4の先端部4aとの間隔が狭くなる。
When the top (lower end) of the inclined cam surface 34c rides on the top of the inclined cam surface 26a of the lower cam member 24, the door 200 stops at the fully open position shown in FIG. 3 (a). Is pushed by hand, and when the top portion (lower end portion) of the inclined cam surface 34c is located near the top portion of the inclined cam surface 26a of the lower cam member 24, the weight of the door 200 causes the upper side. The cam member 34 moves downward while sliding on the inclined cam surface 26 a of the lower cam member 24.
The movement in the direction in which the door 200 is closed by its own weight continues until the door 200 is completely closed, and the entire hinge upper part 3 moves downward while rotating to a position of 180 ° along the inclined cam surface 26a. When the whole hinge upper part 3 starts to move downward, the distance between the tip 5a of the hydraulic damper 5 and the tip 4a of the shaft 4 becomes narrow.

図4(a)に示す扉200が全閉の状態にあるダンパ付きグレビティヒンジ1を図4(b)に示す。
図4(a)に示す扉200が閉じ終える直前の位置に達すると、油圧ダンパ5の先端部5aがシャフト4の先端部4aに当接し、この後、扉200が閉じ終えるまで、扉200の自重による閉じる力に油圧ダンパ5の先端部5aによる押し戻し力が作用する。
油圧ダンパ5の先端部5aによる押し戻し力(油圧ダンパ力)は、ドア200の自重による閉じる力(降下力)よりも小さくなるように設定してある。このため、ドア200が閉じる途中で止まることなく、ゆっくりと閉じ、扉200が閉じたときに大きな衝撃音は発生しない。
FIG. 4B shows the damper-attached gravity hinge 1 in which the door 200 shown in FIG. 4A is fully closed.
When reaching the position immediately before the door 200 shown in FIG. 4A is closed, the front end portion 5a of the hydraulic damper 5 comes into contact with the front end portion 4a of the shaft 4, and then the door 200 is closed until the door 200 is closed. The pushing back force by the front-end | tip part 5a of the hydraulic damper 5 acts on the closing force by dead weight.
The pushing back force (hydraulic damper force) by the tip 5a of the hydraulic damper 5 is set to be smaller than the closing force (descent force) due to the dead weight of the door 200. For this reason, without closing in the middle of the door 200 closing, it closes slowly, and when the door 200 closes, a big impact sound is not generated.

扉200が自重で閉じる力と速度は、扉200の重量により異なる。このため、扉200の重量に対応したダンパ力がある油圧ダンパ5を使用する必要がある。このため、必要なダンパ力が得られる粘度のあるオイルが充填された油圧ダンパ5を使用する。   The force and speed at which the door 200 closes by its own weight varies depending on the weight of the door 200. For this reason, it is necessary to use the hydraulic damper 5 having a damper force corresponding to the weight of the door 200. For this reason, the hydraulic damper 5 filled with the oil with the viscosity which can obtain a required damper force is used.

図4(b)に示す上部側の傾斜カム面34cの頂部が下部側の傾斜カム面26aの底に達した位置、即ち、理論上、扉200が閉じ終える位置を、図4(a)に示すF辺りの位置に設定しておくことが好ましい。このようにすると、扉200が全閉位置でも扉200に閉じる力を残しておくことができ、扉200を完全に閉じさせ続ける。   FIG. 4A shows the position at which the top of the upper inclined cam surface 34c shown in FIG. 4B reaches the bottom of the lower inclined cam surface 26a, that is, the position where the door 200 finishes closing in theory. It is preferable to set the position around F shown. In this way, even when the door 200 is in the fully closed position, the closing force can be left on the door 200, and the door 200 is kept completely closed.

油圧ダンパ5によるダンパ力(押し戻し力)は、扉200を開け始めるときに必要な手の力の負担を軽減させる。   The damper force (push-back force) by the hydraulic damper 5 reduces the burden on the hand force necessary to start opening the door 200.

凸形カム部材26は、保持部材25から抜き挿しして、図5(f)に示す向きから図5(g)に示す向きに、回転方向の向きを変化させることができ、この結果、扉200の開閉角度を、図6に示す略90°の角度にすることも可能弐なる。   The convex cam member 26 can be inserted into and removed from the holding member 25 to change the direction of the rotational direction from the direction shown in FIG. 5 (f) to the direction shown in FIG. 5 (g). The opening / closing angle of 200 can be set to an angle of about 90 ° shown in FIG.

また、図5(f)(g)に示す被係合部26c,26cと係合部25e,25eとによる係合個所を、隣りの係合部25e,25eがある位置に向きを変えると、理論上、図4(a)に示すF位置まで扉200の閉じる力を及ぼすことができる。また、双方の傾斜カム面の頂部が乗り上げる手前の位置を、扉の全開位置に設定することができる。   Further, when the engagement positions of the engaged portions 26c and 26c and the engagement portions 25e and 25e shown in FIGS. 5 (f) and 5 (g) are changed to positions where the adjacent engagement portions 25e and 25e are located, Theoretically, the closing force of the door 200 can be exerted up to the position F shown in FIG. Further, the position in front of the tops of both inclined cam surfaces can be set to the fully open position of the door.
