Description

本発明は、扉を開放する方向にレバーを押し込み操作、または引き寄せ操作することによりスライドラッチを開錠できるプッシュプル錠に関する。   The present invention relates to a push-pull lock that can unlock a slide latch by pushing or pulling a lever in a direction to open a door.

プッシュプル錠は、特許文献１に見られるようにドアの壁面に、内外の取付け座を介して内外のレバーを押し込み操作、または引き寄せ操作により開錠するように構成されている。
しかしこれらのプッシュプル錠は、レバーの押し込み、引き寄せ操作により開錠が可能であるものの、ラッチを軸を中心に回動させて退避させる構造であるため、ラッチそのものの構造が複雑となるばかりでなく、ラッチの後退量がスライドラッチに比較して少ないためドアと枠との間の隙間が大きい場合にはわずかなレバーの移動でも不用意に開錠してしまい危険が伴うという問題がある。 As can be seen in Patent Document 1, the push-pull lock is configured such that the inner and outer levers are pushed onto the wall surface of the door via the inner and outer mounting seats, or unlocked by a pulling operation.
However, although these push-pull locks can be unlocked by pushing and pulling the lever, the structure of the latch itself is complicated because the latch is pivoted about the shaft and retracted. In addition, since the amount of retraction of the latch is smaller than that of the slide latch, there is a problem that when the gap between the door and the frame is large, even a slight movement of the lever unintentionally unlocks the door.

特開２００２−７０３８６JP 2002-70386

本発明は、このような事情に鑑みてなされたものであって、目的とするところはスライドラッチを使用して開錠のためのレバーのストロークを十分に取ることができる信頼性の高いプッシュプル錠を提供することである。   The present invention has been made in view of such circumstances, and the object of the present invention is to provide a highly reliable push-pull that can take a sufficient stroke of a lever for unlocking using a slide latch. Is to provide a lock.

このような課題を達成するために本発明においては、操作レバーの押し込み操作、または引き寄せ操作によりラッチを扉枠の係止孔から退避させるラッチ錠において、滑動により進退するスライドラッチを常時突出方向に付勢して収容するとともに、前記スライドラッチの後端側に長貫通穴が形成されたラッチユニットと、前記長貫通孔に遊嵌して前記操作レバーの押し込み操作、引き寄せ操作により前記スライドラッチを後退させる方向に移動するカム板と、前記押し込み操作されるレバーには前記カム板の前端を前記スライドラッチの係止孔との契合側に押圧する突起部が設けられている。   In order to achieve such a problem, in the present invention, in the latch lock that retracts the latch from the locking hole of the door frame by pushing the operation lever or pulling it, the slide latch that advances and retreats by sliding is always in the protruding direction. The latch unit is energized and accommodated, and a long through hole is formed on the rear end side of the slide latch, and the slide latch is loosely fitted into the long through hole to push and pull the operation lever. A cam plate that moves in a retreating direction and a protrusion that presses the front end of the cam plate to the engagement side with the locking hole of the slide latch are provided on the lever that is pushed in.

スライドラッチが軸方向への滑動により進退する構造であるため、開錠のために必要なストロークを長くすることができ、中途半端なレバーの操作量では施錠状態を維持できて、安全を確保できる。
また、回動により退避させるラッチを使用した場合に比較して構造の簡素化を図ることができる。 Since the slide latch moves forward and backward by sliding in the axial direction, the stroke required for unlocking can be lengthened, and the locked state can be maintained with halfway lever operation, ensuring safety. .
Further, the structure can be simplified as compared with the case where a latch that is retracted by rotation is used.

そこで以下に本発明の詳細を図示した実施例に基づいて説明する。
図１は、本発明のプッシュプル錠の一実施例を示すものであって、スライドラッチユニットを構成するスライドラッチ２は、は滑動により進退するとともに付勢部材１により常時突出するように構成されているとともにその後端側には、ドア３にセットされたときドア３に垂直な方向に延びるカム板４、５が遊嵌、挿入され、カム板４、５の後端（ドア側の端部）により押される壁面２ｂを備えた長貫通穴６（図２）が設けられている。
なお、図１（イ）における二点鎖線で示したレバーの位置は、開錠操作時の状態を示すものである。 Therefore, details of the present invention will be described below based on the illustrated embodiment.
FIG. 1 shows an embodiment of the push-pull lock of the present invention. A slide latch 2 constituting a slide latch unit is configured to advance and retract by sliding and to always protrude by an urging member 1. At the rear end side, cam plates 4 and 5 extending in a direction perpendicular to the door 3 when set on the door 3 are loosely fitted and inserted, and the rear ends of the cam plates 4 and 5 (ends on the door side) ) Is provided with a long through hole 6 (FIG. 2) provided with a wall surface 2b to be pressed.
In addition, the position of the lever shown with the dashed-two dotted line in FIG. 1 (A) shows the state at the time of unlocking operation.

ドア３の表裏となる側には引き寄せ操作用の操作レバー７と、押し込み操作用の操作レバー８とが枢支され、レバー７，８がドア３に垂直な方向に移動するように設けられている。
開錠の際に引き寄せ操作されるレバー７にはカム板４が軸９に枢支されて設けられており、バネ１０により常時レバー７を外側に付勢してドア３の表面から一定の隙間を維持するように構成されている。 An operation lever 7 for pulling operation and an operation lever 8 for pushing operation are pivotally supported on the front and back sides of the door 3, and the levers 7 and 8 are provided so as to move in a direction perpendicular to the door 3. Yes.
A cam plate 4 is pivotally supported by a shaft 9 on the lever 7 that is pulled and operated when unlocking, and the lever 7 is constantly urged outward by a spring 10 so that a certain clearance from the surface of the door 3 is obtained. Is configured to maintain.

一方、開錠の際に押し込み操作されるレバー８は、軸１１に枢支されて設けられ、バネ１２によりレバー８を外側に常時付勢してドア３の表面から一定の隙間を維持するように構成され、またレバー８のドア３の表面側の端部には突起部１３が形成されている。このレバー８に連動するカム板５は、レバー８の突起部１３に契合するように軸１４に枢支されている。これによりレバー８の押し込み操作の運動が軸１１、１４により引き寄せ操作用のレバー７によるカム板４と同一方向に変換される。なお、突起部１３の、カム板５と接触する領域は円弧状に整形されている。   On the other hand, the lever 8 that is pushed in at the time of unlocking is provided so as to be pivotally supported by the shaft 11, and the lever 8 is constantly urged outward by the spring 12 so as to maintain a certain clearance from the surface of the door 3. Further, a protrusion 13 is formed at the end of the lever 8 on the surface side of the door 3. The cam plate 5 interlocked with the lever 8 is pivotally supported on the shaft 14 so as to engage with the protrusion 13 of the lever 8. As a result, the movement of the pushing operation of the lever 8 is converted by the shafts 11 and 14 in the same direction as the cam plate 4 by the lever 7 for pulling operation. In addition, the area | region which contacts the cam plate 5 of the projection part 13 is shaped in the circular arc shape.

これら２枚のカム板４、５は、その後端側（ドア側の端部）が相互干渉しないように上下関係となるようにラッチ２の長貫通穴６に挿入されている。なお、図中符号１６は、戸当たりを示す。   These two cam plates 4 and 5 are inserted into the long through-hole 6 of the latch 2 so that the rear end side (end portion on the door side) is in a vertical relationship so as not to interfere with each other. In addition, the code | symbol 16 in a figure shows the door stop.

この実施例において開錠のために、レバー７をバネ１０の付勢力に抗して引き寄せ操作すると（図３ 符号Ａ）、カム板４が回動して（符号Ｂ）カム板４の後端がラッチ２の長貫通穴６を移動して後壁を付勢力に抗して押圧してラッチ２を後退させるから、ラッチ２が枠１８の係止孔１７から抜けて開錠する。   In this embodiment, when the lever 7 is pulled and operated against the urging force of the spring 10 for unlocking (reference A in FIG. 3), the cam plate 4 rotates (reference B) and the rear end of the cam plate 4 is moved. Moves the long through hole 6 of the latch 2 and presses the rear wall against the urging force to retract the latch 2, so that the latch 2 comes out of the locking hole 17 of the frame 18 and is unlocked.

一方、レバー８をバネ１２の付勢力に抗して押し込み操作すると（図３ 符号Ｃ）、レバー８の突起部１３が軸１１を中心に回動し（符号 Ｄ）、カム板５の先端５ａを軸１４を中心に回動させるため、カム板５の後端は引き寄せ操作用のレバー７が開錠のために操作された際のカム板４と同一の方向、つまりスライドラッチ２を付勢力に抗して後退させる方向に移動して（符号 Ｅ）、ラッチ２が枠１８の係止孔１７から抜けて開錠する。   On the other hand, when the lever 8 is pushed in against the urging force of the spring 12 (reference symbol C in FIG. 3), the protrusion 13 of the lever 8 rotates about the shaft 11 (reference symbol D), and the tip 5a of the cam plate 5 is rotated. Is rotated about the shaft 14, the rear end of the cam plate 5 is in the same direction as the cam plate 4 when the lever 7 for pulling operation is operated for unlocking, that is, the urging force of the slide latch 2. The latch 2 moves out of the locking hole 17 of the frame 18 and is unlocked.

なお、開錠した状態では、それぞれのレバー７，８はバネ１０，１２の付勢力により元の位置に戻るからそれぞれのカム板４，５の後端は長貫通穴６の先端側に位置している。したがってドアを閉めると、ラッチ２はその斜面２ａに押されて後退し、係止孔１７に進入してドア３を施錠状態とする。   In the unlocked state, the levers 7 and 8 are returned to their original positions by the urging force of the springs 10 and 12, so that the rear ends of the cam plates 4 and 5 are located on the front end side of the long through-hole 6. ing. Therefore, when the door is closed, the latch 2 is pushed back by the inclined surface 2a and enters the locking hole 17 to bring the door 3 into a locked state.

このようにスライドラッチ２を滑動により後退させて開錠するため、回動により進退させる従来のプッシュプル錠を使用した従来のプッシュプル錠に比較してラッチ２のストロークを長くすることができ、操作レバー７，８が中途半端に回動した際でも閉錠状態を依然として維持することが可能となり、ドア３とドア枠１８との間隔ｇが多少大きくなってもラッチ２が係止孔１７に契合しているため、閉錠状態を維持して安全性を高めることができる。   Since the slide latch 2 is retracted and unlocked by sliding in this way, the stroke of the latch 2 can be made longer than a conventional push-pull lock using a conventional push-pull lock that is advanced and retracted by rotation. Even when the operation levers 7 and 8 are rotated halfway, the locked state can still be maintained, and the latch 2 is brought into the locking hole 17 even if the gap g between the door 3 and the door frame 18 is slightly increased. Since it is contracted, the locked state can be maintained and safety can be enhanced.

なお、上述の実施例においては押し込み操作用のレバー８の突起部１３が一体に形成されているが、レバー本体部と突起部とに別体に構成して組み付けるようにしても同様の作用を奏することは明らかである。これによれば引き込み操作用レバーと押し込み操作用のレバーを同一の金型で製造できる。   In the above-described embodiment, the protrusion 13 of the lever 8 for pushing operation is integrally formed. However, the same effect can be obtained even if the lever main body and the protrusion are separately configured and assembled. It is clear to play. According to this, the pull-in operation lever and the push-in operation lever can be manufactured with the same mold.
