Description

本発明は、ドアの開閉に用いられる速度調整装置付きドア用ヒンジに関する。   The present invention relates to a door hinge with a speed adjustment device used for opening and closing a door.

開いたドアが速度調整されながら閉じられるようにするドア速度調整装置は、種々開発されているが、ドアの開放位置から閉止位置への回動角度に応じた速度調整を行うための機構は、ドアの上部に、当該ドアのヒンジとは別に取り付けられる箱型のダンパーとされるのが一般的である（例えば、特許文献１）。
しかしながら、美観等の点からは、ドア開閉用に必ず取り付けられるヒンジに、そのような速度調整機能をもたせた方が好ましい。 Various door speed adjustment devices have been developed that allow an open door to be closed while adjusting the speed, but a mechanism for adjusting the speed according to the rotation angle from the opening position of the door to the closing position is as follows: It is common to use a box-shaped damper attached to the upper part of the door separately from the hinge of the door (for example, Patent Document 1).
However, from the point of view of beauty, it is preferable to provide such a speed adjustment function to the hinge that is always attached for opening and closing the door.

以下、本発明に係るドア用ヒンジの実施形態を添付図面に基づき詳細に説明する。
図１は、本発明に係るドア用ヒンジ１０の要部縦断面図であり、右半部分は、後述する速度調整装置が、ドア開放時の状態を示し、左半部分は、ドア閉止時の状態を示している。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a door hinge according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a longitudinal sectional view of a main part of a door hinge 10 according to the present invention. The right half part shows a state where a speed adjusting device described later is in a door open state, and the left half part is in a door closed state. Indicates the state.

図示のように、このヒンジ１０は、ドア枠に取り付けられる第１羽根が固定される第１筒体１２と、ドアに取り付けられる第２羽根が固定され、第１筒体１２と軸線方向で整合された第２筒体１４と、開かれたドアを閉じる際に、該ドアの回動に伴って第２筒体１４が第１筒体１２に対して相対的に回動されるのに対して速度調整を行うための速度調整装置１６と、を有している。 As illustrated, the hinge 10 is aligned with the first cylinder 12 to which the first blade 12 attached to the door frame is fixed, and the second blade attached to the door is fixed and aligned with the first cylinder 12 in the axial direction. When closing the opened second cylinder 14 and the opened door, the second cylinder 14 is rotated relative to the first cylinder 12 as the door rotates. And a speed adjusting device 16 for adjusting the speed.

速度調整装置１６は、第２筒体１４に固定されて第１筒体１２の第１の端部１２−１から同第１筒体内に延びたシャフト１８と、第１筒体内において、該シャフトの端部に対してセレーション接続され、該シャフト１８と共に回動し、且つ、同シャフトに対して軸線方向で変位可能とされたピストン部材２０とを有する。該ピストン部材２０は、第１筒体１２の内周面の雌ネジ１２−３とネジ係合されている雄ネジ２０−１を有しており、シャフト１８が第２筒体１４と共に第１筒体１２に対して相対的に回動することに伴い回動し、第１筒体１２に対して相対的に、図１の左半部分に示す第１軸方向位置と（該第１軸方向位置よりも第１筒体１２の第１の端部１２−１に近い）図１の右半部分に示す第２軸方向位置との間で変位するようになされている。 The speed adjustment device 16 includes a shaft 18 fixed to the second cylinder 14 and extending from the first end 12-1 of the first cylinder 12 into the first cylinder, and the shaft in the first cylinder. And a piston member 20 that is serrated and connected to the end of the shaft, rotates together with the shaft 18, and is displaceable in the axial direction relative to the shaft. The piston member 20 has a male screw 20-1 that is screw-engaged with a female screw 12-3 on the inner peripheral surface of the first cylinder 12, and the shaft 18 together with the second cylinder 14 is the first. The first axis direction position shown in the left half part of FIG. 1 (relative to the first axis 12) and the first axis position relative to the first cylinder 12 (relative to the first axis 12). 1 is closer to the second axial position shown in the right half part of FIG. 1 (closer to the first end 12-1 of the first cylindrical body 12 than to the directional position).

該速度調整装置１６は、また、シャフト１８の第１筒体１２の第２の端部１２−２に、環状の固定部材１７によって固定された、円柱状の流路部材２２を有する。ピストン部材２０は筒状とされており、上記流路部材２２の外周面と上記第１筒状体１２の内周面との間に形成された環状空間に位置しており、第１筒体１２の第１の端部１２−１との間に第１室２４が形成され、第１筒体１２の第２の端部１２−２との間に第２室２６が形成されている。流路部材２２は、シャフト１８との間に、ピストン部材２０によって囲まれた第３室２５を形成しており、該第３室２５は、シャフト１８とピストン２０との間に形成された第１室２４に至る連通路２０−２によって該第１室２４に連通されている。 The speed adjusting device 16 also has a cylindrical flow path member 22 fixed to the second end portion 12-2 of the first cylinder 12 of the shaft 18 by an annular fixing member 17. The piston member 20 has a cylindrical shape, and is located in an annular space formed between the outer peripheral surface of the flow path member 22 and the inner peripheral surface of the first cylindrical body 12. A first chamber 24 is formed between the first end portion 12-1 and the second chamber 26 between the second end portion 12-2 of the first cylinder 12. The flow path member 22 forms a third chamber 25 surrounded by the piston member 20 with the shaft 18, and the third chamber 25 is a second chamber formed between the shaft 18 and the piston 20. The first passage 24 communicates with the first passage 24 through a communication passage 20-2 reaching the first compartment 24.

流路部材２２は、連通路２０−２及び第３室２５を介して、第１室２４と第２室２６との間を連通する一方向流路２８と、第１及び第２速度調整流路３４、３６とを有する。
一方向流路２８は、チェックバルブ３０を有し、ピストン部材２０が（図１の左半部分に示す）第１軸線方向位置から（図１の右半部分に示す）第２軸線方向位置に向けて変位するときに、第１室２４の流体が、連通路２０−２、第３室２５、及び、当該一方向流路２８を通り、第２室２６に流れるのを許容し、ピストン部材２０が逆に第２軸線方向位置から第１軸線方向位置に変位するときは、該一方向流路内を流体が流れるのを阻止する。 The flow path member 22 includes a one-way flow path 28 that communicates between the first chamber 24 and the second chamber 26 via the communication path 20-2 and the third chamber 25, and first and second speed adjustment flows. Paths 34 and 36.
The one-way flow path 28 has a check valve 30, and the piston member 20 moves from a first axial position (shown in the left half portion of FIG. 1) to a second axial position (shown in the right half portion of FIG. 1). The piston member allows the fluid in the first chamber 24 to flow through the communication path 20-2, the third chamber 25, and the one-way flow path 28 to the second chamber 26 when displaced toward the piston chamber. When 20 is displaced from the second axial position to the first axial position, the fluid is prevented from flowing in the one-way flow path.

第１速度調整流路３４は、流路部材２２の外周に設けられた環状溝３４−１と、該環状溝から半径方向内方に延びた半径方向路３４−２と、該半径方向路に接続されて当該ドア用ヒンジの軸線方向に延びて第３室２５に至る軸方向路３４−３と、該軸方向路内に設けられた流路抵抗調節部材３４−４とを有している。流路抵抗調節部材３４−４は、軸方向路３４−３内にネジ係合されており、その軸線を中心に回動して、その軸線方向位置を調節することにより、当該第１速度調整流路３４を通る流体に対する流路抵抗(従って、速度制動力)を調節する。 The first speed adjustment channel 34 includes an annular groove 34-1 provided on the outer periphery of the channel member 22, a radial path 34-2 extending radially inward from the annular groove, and the radial path It has an axial path 34-3 that is connected and extends in the axial direction of the door hinge to reach the third chamber 25, and a flow path resistance adjusting member 34-4 provided in the axial path. . The flow path resistance adjusting member 34-4 is screw-engaged in the axial path 34-3, and rotates about the axis to adjust the position in the axial direction, thereby adjusting the first speed adjustment. The flow path resistance (and hence velocity braking force) for the fluid passing through the flow path 34 is adjusted.

第２速度調整流路３６は、第１速度調整流路２４と同様の構成となっており、流路部材２２の外周に設けられた環状溝３４−１よりも第1筒体の第１端部側に離れた環状溝３６−１と、該環状溝から半径方向内方に延びた半径方向路３６−２と、該半径方向路に接続されて当該ヒンジの軸線方向に延びて第３室２５に至る軸方向路３６−３と、該軸方向路内に設けられた流路抵抗調節部材３６−４とを有しており、流路抵抗調節部材３６−４を、その軸線を中心に回動することにより、当該第２速度調整流路３６を通る流体に対する流路抵抗(従って、速度制動力)を調節するようになっている。 The second speed adjustment flow path 36 has the same configuration as the first speed adjustment flow path 24, and the first end of the first cylindrical body rather than the annular groove 34-1 provided on the outer periphery of the flow path member 22. An annular groove 36-1 spaced apart from the section, a radial path 36-2 extending radially inward from the annular groove, and connected to the radial path and extending in the axial direction of the hinge to form a third chamber 25, and a flow path resistance adjusting member 36-4 provided in the axial path. The flow path resistance adjusting member 36-4 is centered on the axis thereof. By rotating, the flow path resistance (and hence the speed braking force) with respect to the fluid passing through the second speed adjustment flow path 36 is adjusted.

ピストン２０には、半径方向に貫通し、第２室２６に連通している半径方向貫通孔３８が設けられている。該半径方向貫通孔３８は、ピストン部材２０の（図１の右半部分に示す）第２軸線方向位置から（同左半部分に示す）第１軸線方向位置までの行程における初めの第１行程範囲においては、第２速度調整流路３６の環状溝３６−１と連通し、第１行程範囲に続く第２行程範囲においては、第２速度調整流路３６の環状溝３６−１と第１速度調整流路３４の環状溝３４−１とに跨り、最後の第３行程範囲においては、第１速度調整流路３４の環状溝３４−１に連通するようになっている。これをドアの閉止運動との関係で述べれば、ドア閉止運動における第１及び第２筒体１２，１４の相対的回動によって、第２室２６から第１室２４への流体の動きが生じるが、開放位置から比較的大きな角度範囲の間は第２速度調整流路３６を通り、閉止前の比較的小さな角度範囲においては第１速度調整流路３４を通って流れるようになっており、第２速度調整流路３６の流路抵抗を大きく、第１速度調整流路３８の流路抵抗を小さくすれば、ドアはゆっくり安全な速度で閉止運動を行い、閉止が完了する直前では速い閉止運動を行い確実にドアを閉鎖することが出来る。 The piston 20 is provided with a radial through hole 38 that penetrates in the radial direction and communicates with the second chamber 26. The radial through hole 38 is the first first stroke range in the stroke from the second axial position (shown in the right half of FIG. 1) of the piston member 20 to the first axial position (shown in the left half). In the second stroke range that communicates with the annular groove 36-1 of the second speed adjusting flow path 36 and that follows the first stroke range, the annular groove 36-1 and the first speed of the second speed adjusting flow path 36 are provided. It straddles the annular groove 34-1 of the adjustment flow path 34 and communicates with the annular groove 34-1 of the first speed adjustment flow path 34 in the last third stroke range. If this is described in relation to the closing motion of the door, fluid movement from the second chamber 26 to the first chamber 24 is caused by the relative rotation of the first and second cylinders 12 and 14 in the closing motion of the door. However, it flows through the second speed adjustment flow path 36 during a relatively large angle range from the open position, and flows through the first speed adjustment flow path 34 in a relatively small angle range before closing, If the flow resistance of the second speed adjustment flow path 36 is increased and the flow resistance of the first speed adjustment flow path 38 is decreased, the door slowly closes at a safe speed and closes immediately before the closing is completed. You can do the exercise and close the door securely.

以上、本発明に係るドア用ヒンジの一実施形態を説明したが、種々の変形が可能であり、例えば、速度調整流路を必要に応じて３以上設けることにより３以上の角度範囲の速度調整を可能とすることができる。また、持出し吊型のドア閉鎖装置に当該機構を用いることも可能である。また、上述の実施形態においては、ピストン部材に設ける半径方向貫通孔３８を１つとしたが、該ピストン部材に第１及び第２の半径方向貫通孔を設け、第１半径方向貫通路は、ピストン部材が第１の行程範囲にあるときに第１環状溝と連通し、第２半径方向貫通路は、ピストン部材が第２の行程範囲にあるときに第２環状溝と連通するようにすることもできる。この場合、第１半径方向貫通路の第１環状溝との連通と、第２半径方向貫通路の第２環状溝との連通とを時間的重なりがあるようなものとすることもできる。   As mentioned above, although one embodiment of the door hinge according to the present invention has been described, various modifications are possible. For example, by providing three or more speed adjustment flow paths as necessary, speed adjustment in three or more angular ranges is possible. Can be made possible. Moreover, it is also possible to use the said mechanism for a take-out hanging type door closing device. Moreover, in the above-mentioned embodiment, although the one radial direction through-hole 38 provided in a piston member was used, the 1st and 2nd radial direction through-hole is provided in this piston member, and a 1st radial direction through-path is a piston. The member is in communication with the first annular groove when the member is in the first stroke range, and the second radial through passage is in communication with the second annular groove when the piston member is in the second stroke range. You can also. In this case, the communication with the first annular groove of the first radial through passage and the communication with the second annular groove of the second radial through passage may be temporally overlapped.
