ものなどが公知できる。Conventional door checks incorporate a spring, oil and hydraulically operated valve, pinion and rack inside the cylinder.
Something with an external lever and link mechanism, etc.
As shown in Japanese Utility Model Publication No. 160062 or Japanese Utility Model Publication No. 50-36839, there are known systems in which a rotating shaft is inserted into a cylinder and the movement of a piston within the cylinder provides a damping effect.

る率が早い等の欠点があった。However, in the former case, the external shape of the cylinder becomes larger and it is installed between the door and the door frame, so
It does not have a very good appearance, and if a large amount of force is applied to the mounting part, and if the mounting part of the door frame or the door itself is made of wood, the rate of rattling will increase over time. There were drawbacks.

次に」１記実施例についてその作用を説明すると、この
ドアーチェック装置は、新設の場合にはドア弓−の蝶番
と兼用として用い、既設のドアーに取付ける場合には、
既設の蝶番はそのままとして、本発明装置を別に取り付
ける。Next, to explain the function of Example 1, this door check device is used as a hinge for a door bow when a new door is installed, and when installed on an existing door,
The existing hinge is left as is, and the device of the present invention is separately attached.
実施例の場合は新設の場合である。The case of the example is a case of a new installation.
図においで、第１２図はドアー６を閉じた状態を示すも
のである。In the drawings, FIG. 12 shows a state in which the door 6 is closed.
この状態における弁体１５は、第１図に示すように、第
２油室１８側にあり、油は第１油室１７側にある。In this state, the valve body 15 is on the second oil chamber 18 side, and the oil is on the first oil chamber 17 side, as shown in FIG.
この状態にてドアー６を第２図矢印ａ方向に開放すると
、蝶番５を介して回転軸２が第１図矢印す方向に回転す
る。In this state, when the door 6 is opened in the direction of the arrow a in FIG. 2, the rotating shaft 2 rotates via the hinge 5 in the direction of the arrow in FIG.
回転軸２が同転すると、同時に裸線溝１４も回転する。When the rotating shaft 2 rotates, the bare wire groove 14 also rotates at the same time.
この結果、弁体１５の中心は回転軸２に対して偏心して
おり、回転しないので、裸線溝１４に嵌合した突起１５
ｂの作用により、弁体１５は第１図矢印１ｃ方向に上昇
する。As a result, the center of the valve body 15 is eccentric with respect to the rotating shaft 2 and does not rotate, so that the protrusion 15 fitted in the bare wire groove 14
Due to the action of b, the valve body 15 rises in the direction of arrow 1c in FIG.
弁体１５が上昇を開始すると、逆止弁２０は開放し、第
１油室１７例の油は油量１９を通って第２油室１８側に
流れ、油による負荷は殆んどない。When the valve body 15 starts to rise, the check valve 20 opens, and the oil in the first oil chamber 17 flows through the oil volume 19 to the second oil chamber 18 side, and there is almost no load due to the oil.
また、同時に回転軸２が回転すると、カラー１１も一緒
に回転するので、スフ刃ング１０に蓄勢が行なわれる。Furthermore, when the rotating shaft 2 rotates at the same time, the collar 11 also rotates, so that the blade ring 10 is charged with energy.
ドアー６が第２図一点鎖線に示すように全開されると、
弁体１５は第４図に示す位置まで上昇し、油は第２油室
１８側にある。When the door 6 is fully opened as shown in the dashed line in FIG.
The valve body 15 rises to the position shown in FIG. 4, and the oil is on the second oil chamber 18 side.
この状態にてドアー６から手を離すと、先はど行なわれ
たスプリング１０１に対する蓄勢が解除され、回転軸２
はカラー１１を介して先はどとは反対方向に回転せられ
る。When you release your hand from the door 6 in this state, the previously applied energy to the spring 101 is released, and the rotating shaft 2
is rotated through the collar 11 in the opposite direction to the tip.
この結果、ドアー６も閉じる訳であるが、回転軸２が先
はどとは反対方向に回転すると、弁体１５は下降を開始
する。As a result, the door 6 also closes, but when the rotary shaft 2 rotates in the opposite direction, the valve body 15 begins to descend.
しかし、弁体１５の下降に際しては、逆止弁２０は閉じ
、油量１９を油は通らないので、第２油室１８０油室１
８の油は入口２２から迂回油量２１を通って第１油室１
７側に流れる。However, when the valve body 15 is lowered, the check valve 20 closes and no oil passes through the oil volume 19, so the second oil chamber 180 and the oil chamber 1
8 oil passes through the detour oil volume 21 from the inlet 22 to the first oil chamber 1.
Flows to the 7 side.
この際に、ニードル弁２５により油の通る量が制限され
ているため、弁体１５の下降は遅く、回転軸２の回転（
逆転）のブレーキとなる。At this time, since the amount of oil passing through is restricted by the needle valve 25, the lowering of the valve body 15 is slow, and the rotation of the rotating shaft 2 (
(reverse rotation) brake.
この結果、ドアー６は急激に閉じることはなく、ゆっく
りとした速度で自動的に閉じる。As a result, the door 6 does not close abruptly, but automatically closes at a slow speed.
この閉じた状態にも・ける弁態１５の位置に第１図であ
る。FIG. 1 shows the valve valve 15 in its closed position.

きバネに代え得るものである。In addition, in the present invention, the spring 10 is the cylinder 1.
Although a coiled spring is used, this spring can be replaced with a torsion spring (torsion bar, torsion spring) or overwound spring mounted outside the cylinder.

能であると共に体裁もよい。As described above, the present invention inserts the rotating shaft 2 into the cylinder 1, and attaches the cylinder 1 to the door frame 3 side and the rotating shaft 2 to the door 6 side via the hinges 3 and 5 (the reverse is also possible).
, a torsion spring or a thinly wound spring is associated with the rotating shaft 2 to store and release energy, and the rotating shaft 2 (bare wire groove 14, protrusion 15b) and oil movement is eccentrically adjusted together with the valve body 15. Since the brake action is performed by the cylinder 1, the function as a door check is complete, and since the entire mechanism can be incorporated into the cylinder 1, it is possible to reduce the size and look good.
また、新設の場合には蝶番と兼用とすることも出来るの
で、無理な力が取付部分に作用することも少なく、然も
既設のドアーにもそのまま手軽に取り付けて使用するこ
とも出来る利点がある。In addition, in the case of a new installation, it can also be used as a hinge, so there is less stress on the installation part, and it also has the advantage of being able to be easily installed and used on existing doors. .

体１５は一緒に回転しない。Next, the present invention provides the lower end portion 13 of the rotating shaft 2 and the cylinder 1.
Since the relationship between the valve body 15, which divides the oil chamber 16 into the first oil chamber 17 and the second oil chamber 18, is eccentric, the rotating shaft 2 rotates and the bare wire groove 13 in the lower end 13 rotates. Even if a rotational force acts on the valve body 15 via the engaged protrusion 15b, the valve body 15 does not rotate together.
この結果、弁体１５は油室１６内において−Ｌ下動する
。As a result, the valve body 15 moves downward by -L within the oil chamber 16.
よって、弁体１５を上下動はするが、回転軸２と一緒に
回転しないようにするための機構は一切不要となり装置
の小型化とコスＩ・の低下を計ることが可能である。Therefore, although the valve body 15 can be moved up and down, there is no need for any mechanism for preventing it from rotating together with the rotary shaft 2, making it possible to downsize the device and reduce the cost I.
