Description

本発明は、プシュ・プル錠に関し、特に可動体を操作すると、本来的なプッシュ・プル仕様から片面的仕様態様に切り替わるプシュ・プル錠に関する。 The present invention relates to a push-pull lock, and more particularly to a push-pull lock that switches from an original push-pull specification to a one-sided specification mode when a movable body is operated.

特許文献１、特許文献２には、「扉の取付け場所（例えばドアクローザが必要ない室内扉）を考慮し、ユーザーが錠箱の前板から見える可動体の操作部を操作すると、プッシュ・プル仕様から片面的仕様（プル仕様、又はプッシュ仕様）へと切り換るプッシュ・プル錠の具体的構成」が開示されている。 In Patent Document 1 and Patent Document 2, “push-pull specification is considered when the user operates the movable body operation unit that can be seen from the front plate of the lock box in consideration of the installation location of the door (for example, an indoor door that does not require a door closer). "Specific configuration of push-pull lock that switches to single-sided specification (pull specification or push specification)" is disclosed.

これらの発明は、例えばトイレ、寝室等の室内扉の操作ハンドルをプッシュして当該室内側（向こう側）へ勢い良くプッシュして開扉する場合、また、勝手口の扉を室内側の操作ハンドルを操作して室外側へとプッシュして開扉する場合に於いて、ドアクローザが建具に取付けられていないときに有益である。 In these inventions, for example, when an operation handle of an indoor door such as a toilet or a bedroom is pushed to open the door by vigorously pushing to the indoor side (the other side), the door of the doorway is operated to the indoor operation handle. This is useful when the door closer is not attached to the joinery in the case where the door is opened by operating to the outside.

その理由は、プッシュ・プル仕様から片面的仕様（例えばプル仕様）に切り換えると、扉を開ける場合には、一旦手前側にプル操作して扉を開ける必要があるから、扉を向こう側或いは室外側へ勢い良く開扉する事態（お年より等がバランスを崩すこと）を極力防ぐことができるからである。
特開２００４−２１１５２９号公報特開２００４−２２５３８４号公報 The reason for this is that when switching from push-pull specification to single-sided specification (for example, pull specification), when opening the door, it is necessary to open the door by pulling it to the near side. This is because it is possible to prevent as much as possible the situation in which the door is opened to the outside vigorously.

次に、図４は主要部を構成する前板７、固定部材１５、可動部材４０などを示す。図４に於いて、１５は前板７の円形開口１４を基準にして、開口１４縁部の内壁面に固定された固定部材である。固定部材１５は、本実施例では、筒状の支持体である。筒状支持体１５の大きさ及び形状は、摺動部材４７の先端部の位置関係を考慮して適宜に設定される。 (D) Front plate, fixed member, movable member-FIG.
Next, FIG. 4 shows the front plate 7, the fixed member 15, the movable member 40, etc. constituting the main part. In FIG. 4, reference numeral 15 denotes a fixing member fixed to the inner wall surface of the opening 14 with reference to the circular opening 14 of the front plate 7. In this embodiment, the fixing member 15 is a cylindrical support. The size and shape of the cylindrical support 15 are appropriately set in consideration of the positional relationship of the tip portion of the sliding member 47.

筒状支持体１５は、所定長さの収納部１５ａと、この収納部１５ａの先端部に周設したフランジ部１５ｂとを有し、前記フランジ部１５ｂの先端面（外端面）は、前述したように、開口１４を取り囲むように前板１７の裏側（例えば裏面）に複数個の固着具１５ｃを介して固定されている。 The cylindrical support 15 includes a storage portion 15a having a predetermined length, and a flange portion 15b provided around the front end portion of the storage portion 15a. The front end surface (outer end surface) of the flange portion 15b is described above. Thus, it fixes to the back side (for example, back surface) of the front board 17 via the some fixing tool 15c so that the opening 14 may be surrounded.

一方、可動体４０は、筒状支持体１５の収納部１５ａに内装される胴体部分４１と、この胴体部分４１の先端面の中央部に形成された突起軸状の外端部分（先端部分）４２と、胴体部分４１の後端面（内端面）に形成され、かつ、筒状支持体１５の後端面（内端面）から突出する長板状或いは長杆状の障害部分４３とから成る。 On the other hand, the movable body 40 includes a body portion 41 provided in the storage portion 15a of the cylindrical support body 15, and a protruding shaft-shaped outer end portion (tip portion) formed at the center of the front end surface of the body portion 41. 42 and a long plate-like or eaves-like obstacle portion 43 formed on the rear end surface (inner end surface) of the body portion 41 and protruding from the rear end surface (inner end surface) of the cylindrical support 15.

ところで、本実施例の可動体４０は、例えば子供に悪戯され、簡単に仕様が切り換らないように、専用の操作具Ｋを介して所定量回転する。 By the way, the movable body 40 of the present embodiment is rotated by a predetermined amount via the dedicated operation tool K so that the specification is not easily switched because it is mischieved by a child, for example.

そこで、可動体４０には、外端面から内部へと専用の操作具Ｋの先端部分（例えば鍵のブレートに相当する部分）を差し込むことができる挿入溝（例えば鍵穴）４４が形成されている。 Therefore, the movable body 40 is formed with an insertion groove (for example, a key hole) 44 into which a distal end portion (for example, a portion corresponding to a key blade) of the dedicated operation tool K can be inserted from the outer end surface to the inside.

筒状支持体１５の収納部１５ａの適宜箇所に形成した装着小孔には、付勢部材４５が組み込まれている。付勢部材４５は、不番の止め具、クリックバネ、クリックボールから成り、前記クリックボールは、可動体４３の周壁に所定間隔を有して形成された複数個の小係合溝に選択的に係脱する。 A biasing member 45 is incorporated in a mounting small hole formed at an appropriate position of the storage portion 15a of the cylindrical support 15. The urging member 45 is composed of an unnumbered stopper, a click spring, and a click ball, and the click ball is selectively selected from a plurality of small engagement grooves formed at a predetermined interval on the peripheral wall of the movable body 43. To disengage.

また、前記操作具Ｋは、鍵に相当する部材である専用治具である旨を説明したが、専用の操作具Ｋが磁性体である場合には、可動体４０の外端部分の外端面は、前記操作具に吸着し得るように構成される。この点に関して付言すれば、例えば先端部分４２を操作具Ｋの極性に対応して吸着する磁石にするとか、或いは先端部分４２に金属板を固定するとか、或いはまた、可動体４０を吸着可能な金属で製作するとかである。もちろん、専用の操作具Ｋが磁性体である場合には、先端部分４２に挿入溝４４が形成する必要はない。 In addition, it has been described that the operation tool K is a dedicated jig that is a member corresponding to a key. However, when the dedicated operation tool K is a magnetic body, the outer end surface of the outer end portion of the movable body 40. Is configured to be adsorbed to the operation tool. In this regard, for example, the tip portion 42 is made to be a magnet that attracts in accordance with the polarity of the operation tool K, a metal plate is fixed to the tip portion 42, or the movable body 40 can be attracted. For example, it is made of metal. Of course, when the dedicated operation tool K is a magnetic body, it is not necessary to form the insertion groove 44 in the distal end portion 42.

さらに、補足すると、操作具Ｋを可動体４０に差し込んだ場合に可動体４０が錠箱５の内部へ移動しないように、例えば可動体４０の周壁に図示しない周溝を形成し、この周溝に係合する係合突起や係合ピンを外筒体１５側に設けるのが望ましい。 Furthermore, supplementally, for example, a circumferential groove (not shown) is formed on the peripheral wall of the movable body 40 so that the movable body 40 does not move into the lock box 5 when the operation tool K is inserted into the movable body 40. It is desirable to provide an engagement projection and an engagement pin that engage with the outer cylinder 15 on the side.

（ｇ）作用の１−図６
前述したように、この実施例では、前板７の手前から専用の操作具Ｋを介して可動体４０を操作すると、プッシュ・プル錠におけるラッチ施錠片６０の解除態様が、プッシュ・プル仕様又はプル仕様（又はプッシュ仕様）のいずれかに切り替わる。 (G) Action 1-FIG.
As described above, in this embodiment, when the movable body 40 is operated from the front of the front plate 7 via the dedicated operation tool K, the release mode of the latch locking piece 60 in the push-pull lock is the push-pull specification or Switch to either pull specification (or push specification).

まず、図６は可動体４０が略水平状態に位置している場合である。すなわち、可動体４０の障害部分４３が水平状態の場合に於いて、当該操作ハンドル（内外の操作ハンドル如何を問わない）を「プル（引く操作）」又は「プッシュ（押す操作）」した場合である。 First, FIG. 6 shows a case where the movable body 40 is positioned in a substantially horizontal state. That is, when the obstacle portion 43 of the movable body 40 is in a horizontal state, the operation handle (regardless of the operation handle inside or outside) is “pulled” or “pushed”. is there.

この場合プッシュ・プル錠は、本来的意味でのプッシュ・プル仕様である。すなわち、外側の操作ハンドルであろうと、又は内側の操作ハンドルであろうと、手にした当該操作ハンドルを「プル」又は「プッシュ」すると、第１摺動体４６は後退方向へ、又は第２摺動体４７は前進方向へそれぞれ移動する。その結果、ラッチ施錠片６０はダイレクトに、又は揺動レバー５５を介して係合解錠方向へ回動（揺動）する。 In this case, the push-pull lock is a push-pull specification in the original sense. That is, whether the operation handle is an outer operation handle or an inner operation handle, when the operation handle held in hand is “pulled” or “pushed”, the first sliding body 46 moves backward or the second sliding body. 47 respectively move in the forward direction. As a result, the latch locking piece 60 rotates (swings) directly or via the swing lever 55 in the engaging / unlocking direction.

ところで、図１、図６に於いて、ここでは説明の便宜上、第１摺動体４６がプル用として機能した場合（プル用摺動体）、一方、第２摺動体４７がプッシュ用として機能した場合（プッシュ用摺動体）をその作用の一例として説明する。 By the way, in FIG. 1 and FIG. 6, here, for convenience of explanation, when the first sliding body 46 functions for pulling (pull sliding body), on the other hand, when the second sliding body 47 functions for pushing. (Push sliding body) will be described as an example of the action.

すなわち、ここでは外枠の第１摺動体４６（一方）を、内外の操作ハンドルを「プル（引く操作）」した時に水平移動するプル用摺動体とし、内側の第２摺動体４７（他方）を、内外の操作ハンドルを「プッシュ（押す操作）」した時に水平移動するプッシュ用摺動体とする。 That is, here, the first sliding body 46 (one side) of the outer frame is a pulling sliding body that moves horizontally when the inner and outer operation handles are “pulled (pulled)”, and the inner second sliding body 47 (the other). Is a sliding body for push that moves horizontally when the inner and outer operation handles are “pushed (pressed)”.

また、錠箱６の窓孔２０からは、内外の操作ハンドルの上下の押圧片４８，４９が水平状態に入り込んでいるが、図１を基準にして上の押圧片４８が後退（錠箱の後壁に向かって移動）する場合は「プル時」とし、一方、図１を基準にして下の押圧片４９が前進（錠箱の前板に向かって移動）する場合は「プッシュ時」とする。 In addition, the upper and lower pressing pieces 48 and 49 of the inner and outer operation handles enter the horizontal state from the window hole 20 of the lock box 6, but the upper pressing piece 48 moves backward with reference to FIG. “When pulling” when moving toward the rear wall, and “When pushing” when the lower pressing piece 49 moves forward (moves toward the front plate of the lock box) with reference to FIG. To do.

このような前提にて、例えば外側操作ハンドルのプル時（或いは内側操作ハンドルのプル時）には、外枠の第１摺動体４６は上方の押圧片４８に押されて図６矢印Ａの方向に移動する。 Under such a premise, for example, when the outer operation handle is pulled (or when the inner operation handle is pulled), the first sliding body 46 of the outer frame is pushed by the upper pressing piece 48 and the direction of arrow A in FIG. Move to.

したがって、ラッチ施錠片６０は第１摺動体４６の後壁４６ｃ下部に押されることになるから、第１固定軸２１を支点にバネ６３のバネ力に抗して係合解除の方向へダイレクトに回動する。 Therefore, since the latch locking piece 60 is pushed by the lower part of the rear wall 46c of the first sliding body 46, the first locking shaft 21 is used as a fulcrum to resist the spring force of the spring 63 and directly in the direction of disengagement. Rotate.

一方、内側操作ハンドルのプシュ時には、今度は内側の第２摺動体４７が下方の押圧片４９に押されて図６矢印Ｂの方向に移動する。 On the other hand, at the time of pushing the inner operation handle, the inner second sliding body 47 is pushed by the lower pressing piece 49 and moves in the direction of arrow B in FIG.

したがって、ラッチ施錠片６０は、揺動レバー５５がそのバネ５８のバネ力に抗して反時計方向に回動（揺動）することになるから、第１固定軸２１を支点に係合解除の方向へ回転する。 Therefore, the latch locking piece 60 is disengaged with the first fixed shaft 21 as a fulcrum because the swing lever 55 rotates (swings) counterclockwise against the spring force of the spring 58. Rotate in the direction of.

なお、図６の場合に於いて、例えば内側操作ハンドルのプル時には、外枠の第１摺動体４６は下方の押圧片４８に押されて図６矢印Ａの方向に移動する。また内外操作ハンドルのプシュ時には、内側の第２摺動体４７の上下壁４７ａ，４７ｂの先端部４７ｅ，４７ｅは、第２摺動体４７が図６の矢印Ｂ方向へ移動すると、可動体４０の障害部分４３を避けて前進することが可能である。 In the case of FIG. 6, for example, when the inner operation handle is pulled, the first sliding body 46 of the outer frame is pushed by the lower pressing piece 48 and moves in the direction of arrow A in FIG. Further, when the inner / outer operation handle is pushed, the distal end portions 47e and 47e of the upper and lower walls 47a and 47b of the inner second sliding body 47 are obstructed when the second sliding body 47 moves in the direction of arrow B in FIG. It is possible to move forward while avoiding the portion 43.

（ｈ）作用の２−図７
これに対して、図７は可動体４０の障害部分４３が傾斜或いは垂直状態（案内案の形成位置如何）である。この場合には、プッシュ・プル錠におけるラッチ施錠片６０の解除態様が、プッシュ・プル仕様から、いずれか一方の仕様（例えばプル仕様）に切り替わる。 (H) Action 2-FIG.
On the other hand, in FIG. 7, the obstacle portion 43 of the movable body 40 is in an inclined or vertical state (depending on where the guide plan is formed). In this case, the release mode of the latch locking piece 60 in the push / pull lock is switched from the push / pull specification to one of the specifications (for example, the pull specification).

この実施例では、内外の操作ハンドルのプル時に上下の押圧片４８，４９が図６の矢印Ａ方向へ移動することを前提にしているので、かような前提条件の場合には、プッシュ操作時、内側の第２摺動体４７の前進は、可動体４０の障害部分４３に阻まれるので、プッシュ操作でのラッチ施錠片６０の係合解除は不可ということになる。 In this embodiment, it is assumed that the upper and lower pressing pieces 48 and 49 move in the direction of arrow A in FIG. 6 when the inner and outer operation handles are pulled. Since the forward movement of the inner second sliding body 47 is blocked by the obstacle portion 43 of the movable body 40, it is impossible to disengage the latch locking piece 60 by the push operation.

一方、プル操作時、外側の第１摺動体４６は上下いずれかの押圧片４８，４９によって矢印Ａ方向へ移動可能なので、ラッチ施錠片６０は前述したように係合解除の方向へ回転する。したがって、図７の仕様は、本来的なプッシュ・プル仕様でないから、片面的仕様（プル仕様）ということになる。 On the other hand, during the pulling operation, the outer first sliding body 46 can be moved in the direction of arrow A by any one of the upper and lower pressing pieces 48, 49, so that the latch locking piece 60 rotates in the direction of disengagement as described above. Therefore, since the specification of FIG. 7 is not an original push-pull specification, it is a one-sided specification (pull specification).

次に、図１０乃至図１３を参照にして、本発明の第２実施例を説明する。第２実施例は、特許文献２に記載の錠前に本発明を適用したものである。したがって、第２実施例は、錠前５Ａの構造が相違する点を除き、第１実施例と発明の主たる構成は同一である。 Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the present invention is applied to the lock described in Patent Document 2. Therefore, the main structure of the second embodiment is the same as that of the first embodiment except that the structure of the lock 5A is different.

なお、第２実施例の説明にあたって、第１実施例と同一の部分には同一の符号を付して重複する説明を割愛する。また、第２実施例の錠前５Ａの構成・作用を説明するにあたって、特許文献２と同一の部分には、特許文献２と同様の符号（例えばＡを付加）を用いることにする。 In the description of the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals and redundant description is omitted. Further, in describing the configuration and operation of the lock 5A of the second embodiment, the same reference numerals (for example, A is added) as in Patent Document 2 are used for the same parts as Patent Document 2.

したがって、１Ａは戸枠、２Ａは受け金具、３Ａは縁、４Ａは扉、５Ａは錠前（プッシュ・プル錠）、７Ａは前板、１４Ａは開口等である。また、１６Ａは揺動片（押圧片）用の窓、３２Ａは可動枠部材、３３Ａはラッチロッド、３４Ａはラッチ用支持ブロック、３５Ａはラッチ等である。 Therefore, 1A is a door frame, 2A is a metal fitting, 3A is an edge, 4A is a door, 5A is a lock (push-pull lock), 7A is a front plate, 14A is an opening, and the like. Reference numeral 16A denotes a swing piece (pressing piece) window, 32A denotes a movable frame member, 33A denotes a latch rod, 34A denotes a latch support block, and 35A denotes a latch.

さて、第２実施例の錠前５Ａの錠箱６Ａ内には、プッシュ及びプルの操作が可能な内側ハンドルを操作すると、該ハンドル側の揺動片（押圧片）５１Ａの駆動力によって左右（フロント側又はケースの後壁側）にそれぞれ水平移動する一つの同調部材３９Ａ（枠状摺動部材）と、この同調部材３９Ａが水平動すると、該同調部材の上方に配設された板状係合保持部材４１Ｃを介して係合解除の方向（上方方向）に内装ばね４８Ａのバネ力に抗して持ち上げられる可動ストッパー３８Ａと、該可動ストッパー３８Ａによって規制が解消され、かつ、反転式のラッチ３５Ａの回動に伴い、後方配設のばね部材３７Ａのバネ力に抗して錠箱６Ａの後壁側へラッチロッド３３Ａを介して後退する枠状可動枠部材３２Ａが組み込まれている。 Now, in the lock box 6A of the lock 5A of the second embodiment, when the inner handle capable of push and pull operation is operated, the left and right (front) are driven by the driving force of the swing piece (pressing piece) 51A on the handle side. One tuning member 39A (frame-like sliding member) that horizontally moves to the side or the rear wall side of the case, and a plate-like engagement disposed above the tuning member when the tuning member 39A moves horizontally. A movable stopper 38A that is lifted against the spring force of the internal spring 48A in the direction of disengagement (upward direction) via the holding member 41C, the restriction is eliminated by the movable stopper 38A, and the reversing latch 35A In association with this rotation, a frame-like movable frame member 32A is incorporated which moves backward through the latch rod 33A to the rear wall side of the lock box 6A against the spring force of the spring member 37A disposed rearward.

前記ラッチ３５Ａの仮施錠時（可動ストッパー３８Ａが上方の内装バネ４８Ａのバネ力により下方に下降している場合）に於いて、同調部材３９Ａは、錠箱６Ａの下部に左右対称に配設された付勢手段４０Ｆ（可動ブロック４２，付勢ばね４０ｂ）の付勢ばね４０ｂのバネ力により、可動枠部材３２Ａに間接的に係合する位置へと自動的に復帰する。この時、前記可動ストッパー３８Ａは下降しており、係合保持部材４１Ｃの先端係合部は、逆コ字型状の同調部材３９Ａの上壁面に形成された凹所状の被係合部に係合する。 During temporary locking of the latch 35A (when the movable stopper 38A is lowered downward by the spring force of the upper internal spring 48A), the tuning member 39A is disposed symmetrically at the lower part of the lock box 6A. By the spring force of the biasing spring 40b of the biasing means 40F (movable block 42, biasing spring 40b), the position automatically engages with the movable frame member 32A. At this time, the movable stopper 38A is lowered, and the front end engaging portion of the engagement holding member 41C is a recessed engagement portion formed on the upper wall surface of the inverted U-shaped tuning member 39A. Engage.

上記構成に於いて、可動ストッパー３８Ａは、可動枠部材３２Ａに設けた係止部と係脱されると共に、係止部と係合することにより可動枠部材３２Ａの移動を規制してラッチ３５Ａを仮施錠状態にロックする。 In the above configuration, the movable stopper 38A is engaged with and disengaged from the engaging portion provided on the movable frame member 32A, and the movement of the movable frame member 32A is restricted by engaging with the engaging portion, thereby latching the latch 35A. Lock in the temporary locked state.

したがって、この錠前５Ａは、図示しないハンドルをプル又はプッシュすると、錠箱６Ａ内に突出するハンドル側の揺動片５１Ａの駆動力により、かつ、付勢手段４０Ｆの付勢力に抗して水平移動する同調部材３９Ａ、この同調部材３９Ａに連動するようにラッチロッド３３Ａに案内される可動枠部材３２Ａ内に組み込まれた可動ストッパー３８Ａ、この可動ストッパー３８Ａを介して可動枠部材３２Ａの規制を解消するラッチ用仮施錠の解錠機構を備えたプッシュ・プル錠である。 Accordingly, when the handle (not shown) is pulled or pushed, the lock 5A moves horizontally by the driving force of the swing piece 51A on the handle side protruding into the lock box 6A and against the biasing force of the biasing means 40F. The tuning member 39A to be moved, the movable stopper 38A incorporated in the movable frame member 32A guided by the latch rod 33A so as to be interlocked with the tuning member 39A, and the restriction of the movable frame member 32A are canceled via the movable stopper 38A. This is a push-pull lock equipped with a temporary unlocking mechanism for latch.

そして、本発明の第２実施例は、錠箱５Ａの前板７Ａの開口１４Ａを基準にして該前板７Ａの裏面に筒状の支持体１５を固定し、この支持体１５に外端部分４２が位置するように可動体４０を回転自在に内装し、仕様態様の切替え時、可動体４０の先端部分４２を前板側から操作具Ｋを介して操作すると、前記可動体４０の前記筒状の支持体１５の内端面から突出する障害部分４３は、前記同調部材３９Ａの前進を阻止するように位置変位して、本来的なプッシュ・プル仕様から片面的仕様態様に切り替わる。 In the second embodiment of the present invention, a cylindrical support 15 is fixed to the back surface of the front plate 7A with reference to the opening 14A of the front plate 7A of the lock box 5A. When the movable body 40 is rotatably mounted so that the position 42 is located, and the tip portion 42 of the movable body 40 is operated from the front plate side via the operation tool K when the specification mode is switched, the cylinder of the movable body 40 is moved. The obstacle portion 43 protruding from the inner end surface of the support member 15 is displaced so as to prevent the advancement of the tuning member 39A, and the original push / pull specification is switched to the one-sided specification mode.

図１１で示すように、可動体４３の可動部分４３は、操作具Ｋを介して、その位置が変位（移動）する。その他基本的構成及び作用・効果は第１実施例と同一である。
したがって、図１２は、本来的なプッシュ・プル仕様の説明図であり、一方。図１３は、可動体４３の障害部分４３が同調部材３９Ａの先端部に対向して、該同調部材３９Ａの前進が阻止され、本来的なプッシュ・プル仕様からプル仕様の片面的仕様態様に切り替わる説明図である。 As shown in FIG. 11, the position of the movable portion 43 of the movable body 43 is displaced (moved) via the operation tool K. Other basic configurations and operations / effects are the same as those of the first embodiment.
Therefore, FIG. 12 is an explanatory diagram of the original push-pull specification, on the other hand. In FIG. 13, the obstacle 43 of the movable body 43 faces the tip of the tuning member 39 A so that the advancement of the tuning member 39 A is prevented, and the original push-pull specification is switched to the single-sided specification mode of the pull specification. It is explanatory drawing.
