Description

本発明はラッチ錠用のハンドル装置に関し、例えば一端部が台座に軸支された室内側のハンドルを、扉の開く方向へ押す（プッシュする）際、一端部の枢軸を支点にハンドルが所定角度まで傾倒するハンドル揺動型のラッチ錠用ハンドル装置に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle device for a latch lock. The present invention relates to a handle device for a latch lock of a handle swinging type tilting to a position.

特許文献１の第１図に於いて、ラッチ錠Ｂを備えた扉Ａの左壁面（内壁面）に、上下方向に所定間隔を有して固定される上下一組の台座５、６と、これらの台座に垂直方向に架設した状態で両端部が支持されると共に付勢バネにより初期位置に付勢された室内側ハンドル２と、前記上方の台座６の内部に中間部が軸支されていると共に、その下端部側に相当する受動部８ａが前記室内側ハンドル２の自由端部に係合し、かつ、水平部側に相当する係合部が扉Ａの内壁面に形成した開口部を介して前記ラッチ錠Ｂの錠箱内に突出状態に臨むＬ字形状の作動片８とから成るラッチ錠用のハンドル装置が開示されている（符号は文献に記載のもの）。 In FIG. 1 of Patent Document 1, a pair of upper and lower bases 5 and 6 fixed to the left wall surface (inner wall surface) of the door A provided with the latch lock B with a predetermined interval in the vertical direction; Both ends are supported in a state of being erected on these pedestals in the vertical direction, and an intermediate portion is pivotally supported in the interior of the indoor handle 2 urged to an initial position by a urging spring and the upper pedestal 6. In addition, the passive portion 8a corresponding to the lower end side engages with the free end portion of the indoor handle 2 and the engaging portion corresponding to the horizontal portion side is formed in the inner wall surface of the door A. There is disclosed a handle device for a latch lock comprising an L-shaped actuating piece 8 projecting into a lock box of the latch lock B via a lock (reference numeral is described in the literature).

このラッチ錠用のハンドル装置（特許文献１では、プッシュ・プル錠のハンドル装置）は、ハンドル揺動型のもので、前記室内側ハンドル２を扉Ａの開く方向（図面では符合のニ）へプッシュすると、ハンドルの一端部を軸支する枢軸２ａが支点となって室内側ハンドル２の自由端部が室内方向へ所定量位置変位する。 The handle device for the latch lock (in Patent Document 1, the handle device for the push-pull lock) is of a handle swing type, and the indoor handle 2 is moved in the direction in which the door A is opened (reference numeral D in the drawing). When pushed, the pivot 2a that pivotally supports one end of the handle serves as a fulcrum, and the free end of the indoor handle 2 is displaced by a predetermined amount in the indoor direction.

該特許文献１に記載されているように、室内側ハンドル２のプッシュの操作力によって、作動片８が回転すると、ラッチ錠Ｂの錠箱内に組み込まれたラッチ操作部材（駆動体としてのラッチカム）を介してラッチの後退或いは後退動を許容させてラッチ錠Ｂを解錠する共に、扉Ａをプッシュする方向へと開くことができる。 As described in Patent Document 1, when the operating piece 8 is rotated by the push operating force of the indoor handle 2, a latch operating member (latch cam as a driving body) incorporated in the lock box of the latch lock B is used. The latch lock B can be unlocked by allowing the latch to retreat or retreat through), and the door A can be opened in the pushing direction.

ところで、特許文献１の実施例を含め、ハンドル揺動型のラッチ錠用ハンドル装置は、ハンドルの作動方向の力が全て扉を開放させる力として作用させるので、台座内に軸支された作動片を回動させかつ扉を開放するのに要する力は比較的小さくて良いという利点がある。しかしながら、この場合、ハンドルを台座に向かってプッシュすると、ハンドルの端部側の外壁面が台座の外向き凹所内に入り込むので、不注意により指を前記外向き凹所内に突っ込む危険性がある。 By the way, since the handle device for the latch lock handle of the handle swing type including the embodiment of Patent Document 1 operates all the force in the operation direction of the handle as the force for opening the door, the operation piece pivotally supported in the pedestal There is an advantage that the force required to rotate the door and open the door may be relatively small. However, in this case, when the handle is pushed toward the pedestal, the outer wall surface on the end side of the handle enters the outward recess of the pedestal, and there is a risk of inadvertently thrusting the finger into the outward recess.

また、普通一般に、この種のハンドルの台座内には、プッシュ式のハンドルを初期位置側に向けて付勢する付勢バネが存在するので、いわゆるソフトなタッチで、該ハンドルを把持したままの状態で初期位置へと戻すことができるものの、ハンドルと台座の外向き凹所との間に隙間がある場合には、指先や手の平の皮膚を挟むような事故もあり得る。 In general, there is a biasing spring that biases the push-type handle toward the initial position in the pedestal of this type of handle, so that the handle can be held with a so-called soft touch. Although it can be returned to the initial position in a state, if there is a gap between the handle and the outward recess of the pedestal, there may be an accident that pinches the fingertip or palm skin.

そこで、プッシュ式のハンドルの場合に於いて、特に操作時に指や皮膚を挟まない工夫が要望されている。それと同時に、悪戯対策、意匠上の美的外観等の理由から、初期位置乃至ハンドルを操作した時、ハンドル装置を構成する台座の外向き凹所内の作動リンク、軸等を常に隠すことが要望されている。さらに、好ましくは作動リンク、連動レバー等を台座の外向き凹所内に簡単に組付けること、作動リンクを所定の範囲でスムースに前後移動させること等も要望されている。 Therefore, in the case of a push-type handle, there is a demand for a device that does not pinch fingers or skin during operation. At the same time, there is a need to always hide the operating links, shafts, etc. in the outward recesses of the pedestal that constitutes the handle device when the handle is operated from the initial position or the handle for reasons such as countermeasures against mischief and aesthetic appearance in design. Yes. Furthermore, it is desired that the operating link, the interlocking lever and the like are preferably assembled easily in the outward recess of the base, and the operating link is moved back and forth smoothly within a predetermined range.

なお、特許文献２には、家具等における扉のラッチ装置に於いて、扉を閉める際、ラッチと別個のラッチレバーを動かないように軸支し、操作する指を引手部の開口縁部に挟まないことを発明の課題とするものが存在するが、この特許文献２は、プッシュ・プル錠のハンドル装置、特に、プッシュ式のハンドル装置に関するものではない。 In Patent Document 2, in a door latch device in furniture or the like, when closing the door, the latch lever separate from the latch is supported so that it does not move, and the finger to be operated is placed on the opening edge of the pulling portion. Although there exists a thing which makes it the subject of invention not to pinch | interpose, this patent document 2 is not related with the handle apparatus of a push-pull lock, especially a push-type handle apparatus.

本願発明の目的は、（ａ）プッシュ式のハンドルの場合に於いて、操作時に指や皮膚を挟まないことである。（ｂ）また初期位置乃至ハンドルを操作した時に於いて、ハンドル装置を構成する台座の外向き凹所内の作動リンク、可動ピン等を常に目隠しすることである。これにより、子供らが悪戯をして指や皮膚を挟まないようにすることである。 An object of the present invention is (a) in the case of a push-type handle, a finger or skin is not pinched during operation. (B) Further, when the handle is operated from the initial position or the handle, the operating link, the movable pin, etc. in the outward recess of the pedestal constituting the handle device are always blinded. This is to prevent children from mischievously pinching their fingers and skin.

本願発明のラッチ錠用のハンドル装置は、台座に外向き凹所を形成し、この外向き凹所内に位置するハンドルの端部側の外壁面をカバーするカバー体の基端部を前記外向き凹所の外側開口端部に軸支し、その初期位置では該カバー体は前記台座の両側壁端部の端面に支持され、該カバー体はプッシュ式ハンドルを付勢バネのバネ力に抗してプッシュする際には障壁となって前記外向き凹所に指が入り込むのを防止し、一方、前記プッシュ式ハンドルを初期位置へと戻した時には、前記指をカバー体の自由端と前記プッシュ式ハンドルの外壁面との間に挟まないように外方向へ逃げることを特徴とする。 A handle device for a latch lock according to the present invention is formed with an outward recess in a pedestal, and the base end portion of the cover body covering the outer wall surface on the end side of the handle located in the outward recess is directed outward. It is pivotally supported at the outer opening end of the recess, and in its initial position, the cover body is supported by the end surfaces of the both side wall ends of the pedestal, and the cover body resists the spring force of the biasing spring. When the push handle is pushed, it becomes a barrier to prevent the finger from entering the outward recess, and when the push handle is returned to the initial position, the finger is pushed to the free end of the cover body and the push It escapes outward so as not to be pinched between the outer wall surfaces of the type handle.

上記構成に於いて、カバー体は、自重又は該カバー体の基端部側に配設された戻しバネのバネ力のいずれかによって初期位置へと戻ることを特徴とする。この場合、前記戻しバネに代えて磁性体を、例えば台座の両側壁端部の端面とカバー体の自由端にそれぞれ設け、極性に対応してカバー体が外向き凹所の外側開口端を閉じるようにしても良い。また、台座のプッシュ式ハンドルの端部寄りの内側壁面に切欠開口が形成され、一方、常に該切欠開口をカバーする第２カバー体をプッシュ式ハンドルの端部寄りの内壁面に突設し、該第２カバー体はハンドル操作時に前記内側壁面に沿って移動することを特徴とする。 In the above configuration, the cover body returns to the initial position by either its own weight or the spring force of the return spring disposed on the base end side of the cover body. In this case, instead of the return spring, a magnetic body is provided on, for example, the end surface of the both side walls of the pedestal and the free end of the cover body, and the cover body closes the outer opening end of the outward recess according to the polarity. You may do it. Further, a notch opening is formed on the inner wall surface of the pedestal near the end of the push type handle, while a second cover body that always covers the notch opening protrudes from the inner wall surface near the end of the push type handle, The second cover body moves along the inner wall surface when a handle is operated.

（ａ）好ましい実施形態として、プッシュ式ハンドルの端部側の外壁面には、台座の外向き凹所の外側開口端を閉塞状態に覆う端面コ字形状或いは板状カバー体の基端部が回転自在に軸支され、端面コ字形状、板状等のカバー体は、その両側端部の内面が前記台座の両側壁端部の端面に支持されるように前記外向き凹所内に組み込まれた戻しバネで閉塞方向に付勢する。そうすると、子供らが悪戯をして指や皮膚を挟まないようにすることができると共に、プッシュ時、不注意により指を台座の外向き凹所に指を突っ込むことがない。
（ｂ）また、プッシュ式ハンドルを初期位置へと戻した時、仮に把持中の指がカバー体の端部内面に衝突した場合であっても、該カバー体は基端部を支点にしてその自由端が外方向へ逃げるので、指をカバー体１２の自由端とプッシュ式ハンドルの外壁面との間に挟むようなことはない。
（ｃ）ハンドルの端部側に連結された連結片、可動ピン、作動リンク等がカバー体で常に覆われるので、見た目も違和感がなく（体裁が良く）、また子供らが悪戯をして指や皮膚を挟まないようにすることもできるから、安全である。
（ｄ）請求項２に記載の発明は、例えば戻しバネ１９の一端部をカバー体の自由端部に連結する必要がないので、ハンドルの操作時、指が戻しバネ１９に接触するような態様を回避することができる。
（ｅ）請求項３に記載の発明は、台座のプッシュ式ハンドルの端部寄りの内側壁面４ｂに切欠開口１７が形成され、一方、該切欠開口１７をカバーする第２カバー体１８をプッシュ式ハンドル６の端部寄りの内壁面に突設しているので、子供らが悪戯をして指を切欠部分に入れる態様を防止することができる。 (A) As a preferred embodiment, on the outer wall surface on the end side of the push-type handle, there is an end face U-shaped or a base end portion of the plate-like cover body covering the outer opening end of the outward recess of the pedestal in a closed state The cover body, which is pivotally supported and has a U-shaped end surface, a plate shape, and the like, is incorporated in the outward recess so that the inner surfaces of both side end portions thereof are supported by the end surfaces of both side wall end portions of the pedestal. The return spring is urged in the closing direction. This prevents children from playing mischief and pinching their fingers and skin, and does not inadvertently push their fingers into the outward recesses of the pedestal when pushing.
(B) Further, when the push handle is returned to the initial position, even if the finger being gripped collides with the inner surface of the end of the cover body, the cover body has its base end as a fulcrum. Since the free end escapes outward, the finger is not pinched between the free end of the cover body 12 and the outer wall surface of the push handle.
(C) Since the connecting piece, the movable pin, the operating link, etc. connected to the end of the handle are always covered with the cover body, the appearance does not feel strange (the appearance is good), and the children play mischief It is safe because it can prevent the skin from getting caught.
(D) In the invention described in claim 2, for example, it is not necessary to connect one end portion of the return spring 19 to the free end portion of the cover body, so that the finger contacts the return spring 19 when the handle is operated. Can be avoided.
(E) According to the invention described in claim 3, the notch opening 17 is formed in the inner wall surface 4b near the end of the push handle of the base, while the second cover body 18 that covers the notch opening 17 is pushed. Since it protrudes on the inner wall surface near the end of the handle 6, it is possible to prevent the children from mischievously putting their fingers into the notch.

A pivot 23 pivotally supported on the other hand, and a movable end 27a that is displaced inward and outward are pivotally connected via a connecting protrusion 22 and a movable pin 24 on the free end 6b side of the outer handle 6, and A base end portion corresponding to the lower end portion is pivotally supported by a first fixed shaft 25 that is horizontally installed in the outward recess 31 (space portion) of the upper pedestal 4A, and an intermediate portion thereof has a stopper function. An actuating link 27A guided by means 26; A driven engagement tooth 30b meshing with an operation engagement tooth 27b formed on the base end side of the operation link 27A is formed on the base end side, and a second fixed shaft separate from the first fixed shaft 25. 29, and an interlocking lever 30 having an elongate portion 30a that interlocks with the operating link 27A and engages with the passive protrusion b of the driving body a of the latch lock 3.

これに対して、プッシュ側のハンドル装置Ｙは、前記扉２の内壁面２ｂに所定間隔を有して固定される一組の台座４，５と、これらの台座４，５に架設した状態で両端部が支持されると共に、台座４内の付勢バネ２１により初期位置に付勢された内側ハンドル６と、この内側ハンドル６を扉２の開く方向へプッシュすると、内側ハンドル６の一端部を軸支する枢軸２３が支点となって前記台座４，５の一方の台座４に第１固定軸２５を介して軸支されかつ該内側ハンドルの自由端部６ｂに連結された作動リンク２７の可動ピン２４が台座４の内方向へ所定量位置変位すると共に、該作動リンク２７に連動するように前記一方の台座４に第２固定軸２９を介して軸支された連動レバー３０とから成るラッチ錠用のハンドル装置である点は、プル側のハンドル装置Ｘと同様である。 On the other hand, the push-side handle device Y has a set of pedestals 4 and 5 fixed to the inner wall surface 2b of the door 2 with a predetermined interval, and is installed on these pedestals 4 and 5. When both ends are supported and the inner handle 6 is urged to the initial position by the urging spring 21 in the pedestal 4 and the inner handle 6 is pushed in the opening direction of the door 2, one end of the inner handle 6 is moved. A movable link 27 is pivotally supported by one pivotal base 23 of the bases 4 and 5 via a first fixed shaft 25 and connected to the free end 6b of the inner handle. The pin 24 is displaced by a predetermined amount inward of the pedestal 4 and is a latch comprising an interlocking lever 30 pivotally supported on the one pedestal 4 via a second fixed shaft 29 so as to be interlocked with the operating link 27. The point of the handle device for the lock is the pull It is similar to the handle device X for.

しかしながら、プッシュ側のハンドル装置Ｙの前記作動リンク２７は直線的な長杆状に形成されており、一方、前記連動レバー３０はピストル型のアングル形状に形成され、回転半径の異なる異形の前記作動リンク２７及び連動レバー３０の各中間部分は、連係手段（案内長孔２６ａ，係合ピン２６ｂ）２６を介して互いに係合し、また、前記連動レバー３０の先端部に相当する突出端部３０ａは、一方の台座４の取付けベース面４ａの内側開口３６から突出した状態で前記ラッチ錠３の駆動体ａの受動突起部ｂと係合する。 However, the operating link 27 of the handle device Y on the push side is formed in a linear elongate shape, while the interlocking lever 30 is formed in a pistol-shaped angle shape, and the operation of the deformed shape having a different turning radius. The intermediate portions of the link 27 and the interlocking lever 30 are engaged with each other via a connecting means (guide long hole 26a, engaging pin 26b) 26, and a protruding end 30a corresponding to the tip of the interlocking lever 30. Engages with the passive protrusion b of the driving body a of the latch lock 3 in a state of protruding from the inner opening 36 of the mounting base surface 4a of the one pedestal 4.

しかして、プル側のハンドル装置Ｘの前記外側ハンドル（プル式ハンドル）６Ａの端部側６ｂの内壁面には、前記台座４Ａの外向き凹所３１の外側開口端３１ａを閉塞状態に覆うケース状カバー体１２Ａを固定し、該ケース状カバー体１２Ａは、プル式ハンドル６Ａを付勢バネ２１のバネ力に抗してプルした場合であっても、該プル式ハンドル６の前後移動の範囲内で前記台座４Ａの外向き凹所３１の外側開口端３１ａの略全部又は全部を隠し、一方、前記ハンドル６Ａを初期位置へと戻した時には、前記台座４Ａの内側壁面４ｂに対して前記ケース状カバー体１２Ａの把持側内面板１３が略隙間のないように或いは摺接状態に前記外向き凹所３１内に入り込む。 Thus, the inner wall surface of the end side 6b of the outer handle (pull handle) 6A of the pull-side handle device X covers the outer open end 31a of the outward recess 31 of the base 4A in a closed state. Even when the pull-type handle 6A is pulled against the spring force of the urging spring 21, the pull-type handle 6 can be moved in the front-rear range. When the handle 6A is returned to the initial position when the outer open end 31a of the outward recess 31 of the pedestal 4A is concealed, the case 6 is placed against the inner wall surface 4b of the pedestal 4A. The grip-side inner surface plate 13 of the cover member 12A enters the outward recess 31 so that there is almost no gap or is in sliding contact.

これに対して、プッシュ側のハンドル装置Ｙの前記台座４の外向き凹所３１内に位置する内側ハンドル６の端部側６ｂの外壁面には、前記外向き凹所３１の外側開口端３１ａを閉塞状態に覆う板状カバー体１２の基端部（例えば上端部）が回転自在に軸支され、該板状カバー体１２は、その両側端部（例えば左右端部）の内面が、例えば図１３で示すように、前記台座４の両側壁端部の端面４ｃ、４ｃに支持されるように前記外向き凹所内に組み込まれた戻しバネ１９で閉塞方向に付勢され、該板状カバー体１２は、プッシュ式ハンドル６を付勢バネ２１のバネ力に抗してプッシュする際には前記外向き凹所３１に指が入り込むのを防止し、一方、前記ハンドル６を初期位置へと戻した時には、前記指を板状カバー体１２の自由端とハンドル６の外壁面との間に挟まないように前記戻しバネ１９のバネ力に抗して外方向へ逃げる（特徴部分）。 On the other hand, on the outer wall surface on the end side 6b of the inner handle 6 located in the outward recess 31 of the pedestal 4 of the push-side handle device Y, the outer opening end 31a of the outward recess 31 is provided. The base end portion (for example, the upper end portion) of the plate-like cover body 12 that covers the cover in a closed state is rotatably supported, and the inner surface of both side end portions (for example, left and right end portions) of the plate-like cover body 12 is, for example, As shown in FIG. 13, the plate-like cover is urged in the closing direction by a return spring 19 incorporated in the outward recess so as to be supported by end faces 4c, 4c of both side wall ends of the pedestal 4. When the body 12 pushes the push handle 6 against the spring force of the biasing spring 21, the body 12 prevents a finger from entering the outward recess 31, while the handle 6 is moved to the initial position. When the finger is returned, the finger is placed on the free end of the plate-like cover body 12 and the handle. It escapes outward the back against the spring force of the spring 19 to pinch between the outer wall surface (characteristic portion).

そして、本実施例では、図９で示すように、板状カバー体１２の基端部１２ａの内壁面に軸受け部を有する腕状バネ端支持片１５，１５が左右一対突設されており、板状カバー体１２の基端部側に配設された戻しバネ１９は、その一端部１９ａは前記腕状バネ端支持片１５の先端部に形成した凹所状のバネ端支持部分１５ａに圧接し、その他端部１９ｂは外向き凹所３１を形成する開口端付近の内壁上面３１ｂに支持されている。 In this embodiment, as shown in FIG. 9, arm-like spring end support pieces 15, 15 having bearing portions are provided on the inner wall surface of the base end portion 12 a of the plate-like cover body 12, and a pair of left and right protrusions are provided. The return spring 19 disposed on the base end side of the plate-like cover body 12 has one end 19a pressed against a recessed spring end support portion 15a formed at the tip end of the arm-like spring end support piece 15. The other end 19 b is supported by the inner wall upper surface 31 b near the opening end forming the outward recess 31.

また、図６で示すように、台座４の内側壁面４ｂ（図６では底壁部分）に切欠開口１７が形成され、一方、該切欠開口１７をカバーする第２の板状カバー体１８をプッシュ式ハンドル６の端部側６ｂの内壁面に水平方向へと突設し、該第２の板状カバー体１８はプッシュ式のハンドル６を付勢バネ２１のバネ力に抗してプッシュした際に前記台座４の内側壁面４ｂに沿ってスライド状態に移動する。 Further, as shown in FIG. 6, a notch opening 17 is formed in the inner wall surface 4 b (bottom wall portion in FIG. 6) of the base 4, and on the other hand, a second plate-like cover body 18 that covers the notch opening 17 is pushed. When the second plate-shaped cover body 18 is pushed against the spring force of the urging spring 21, the second plate-like cover body 18 projects horizontally on the inner wall surface of the end side 6b of the type handle 6. Next, it moves to a sliding state along the inner wall surface 4b of the pedestal 4.

ところで、図７は、上方台座の正面図である、また、図８は支持枠３９の説明図である。例えば図４で示すように、上方台座４も下方台座５も、取付けベース４ａ、５ａの反対側の外壁弧状面に外向き凹所（空間部分）３１，３２がそれぞれ形成され、これらの外向き凹所３１，３２内に内側ハンドル６（外側ハンドル６Ａも同様）の両端部の略全部が隠蔽状態に入り込んでいると共に、前記内側ハンドル６の自由端部６ｂの内壁面には板状カバー体１２（外側ハンドル６Ａの場合にはケース状カバー体１２Ａ）が固定されている。これは本発明の課題、意匠上の美観性、考案上のハンドルの把持部分の範囲性等を考慮したものである。 FIG. 7 is a front view of the upper pedestal, and FIG. 8 is an explanatory view of the support frame 39. For example, as shown in FIG. 4, both the upper base 4 and the lower base 5 have outward recesses (space portions) 31 and 32 formed on the outer wall arcuate surfaces on the opposite side of the mounting bases 4a and 5a. In the recesses 31 and 32, substantially all of both ends of the inner handle 6 (the same applies to the outer handle 6A) are concealed, and the inner wall surface of the free end 6b of the inner handle 6 is covered with a plate-like cover body. 12 (in the case of the outer handle 6A, a case-like cover body 12A) is fixed. This takes into consideration the problems of the present invention, the aesthetics of the design, the range of the grip portion of the handle in the design, and the like.

また、支持枠３９（プル側のハンドル装置Ｘのそれも同様）は、取付けベース４ａに固定される垂直固定板３９ａの中央部に連動レバー３０が貫通する窓３３を有する。また、前記垂直固定板３９ａに連設状態で交差する対向案内板３９ｂ、３９ｂには、第１固定軸用孔３４と第２固定軸用孔３５がそれぞれ別個・独立に形成されていると共に、前述した案内長孔２６ａ、２６ａが弧状に形成されている。 Further, the support frame 39 (the same as that of the pull-side handle device X) has a window 33 through which the interlocking lever 30 penetrates at the center of the vertical fixing plate 39a fixed to the mounting base 4a. In addition, a first fixed shaft hole 34 and a second fixed shaft hole 35 are formed separately and independently in the opposing guide plates 39b and 39b intersecting with the vertical fixed plate 39a in a continuous manner, The aforementioned guide long holes 26a, 26a are formed in an arc shape.

このように、本実施例では、作動リンク２７を軸支する第１固定軸２５と、連動レバー３０を軸支する第２固定軸２９は別個であり、これらの第１固定軸２５及び第２固定軸２９は外向き凹所３１内に固定された支持枠３９にそれぞれ軸架されているので、作動リン２７及び連動レバー３０を台座の外向き凹所内に容易に組み付けることができる。付言すると、本実施例では、支持機能及びガイド機能を有する単数の支持枠３９を介して上方台座４の外向き凹所３１内に作動リンク２７と連動レバー３０をそれぞれ基端部が係合するように組み込むので、上方台座４（４Ａ）には、ガイド手段、第１固定軸用軸孔、第２固定軸用軸孔等を形成する必要はなく、連動レバー３０用開口３６のみを形成すれば良い。 Thus, in the present embodiment, the first fixed shaft 25 that pivotally supports the operating link 27 and the second fixed shaft 29 that pivotally supports the interlocking lever 30 are separate, and the first fixed shaft 25 and the second fixed shaft 25 are separated. Since the fixed shaft 29 is mounted on the support frame 39 fixed in the outward recess 31, the operating ring 27 and the interlocking lever 30 can be easily assembled in the outward recess of the base. In addition, in this embodiment, the base end portions of the operating link 27 and the interlocking lever 30 engage with each other in the outward recess 31 of the upper base 4 via a single support frame 39 having a support function and a guide function. Therefore, it is not necessary to form the guide means, the first fixed shaft shaft hole, the second fixed shaft shaft hole, or the like in the upper base 4 (4A), and only the interlock lever 30 opening 36 is formed. It ’s fine.

上記構成に於いて、図６で示すように、内側ハンドル６の端部側６ｂの外壁面には板状カバー体１２が添設状態に設けられ、内側ハンドル６をプッシュ操作しない初期状態では、その両側端部の内面が前記台座４の両側壁端部の端面４ｃ，４ｃに支持されるように外向き凹所３１内に組み込まれた戻しバネ１９で閉塞方向に付勢されている。 In the above configuration, as shown in FIG. 6, in the initial state where the plate-like cover body 12 is attached to the outer wall surface of the end side 6 b of the inner handle 6 and the inner handle 6 is not pushed, The inner surfaces of both side end portions are urged in the closing direction by the return springs 19 incorporated in the outward recesses 31 so as to be supported by the end surfaces 4c, 4c of the both side wall end portions of the pedestal 4.

そこで、図１３で示すように、例えば内側ハンドル６の板状カバー体１２の自由端部１２ｂ付近の部位を握って台座４の取付けベース４ａ側（矢印Ａ方向）に押し込むと、例えばハンドルを握った或いは押し込んだ人差し指ｆは、板状カバー体１２が閉塞状態に位置しているので、外向き凹所３１内に不注意により入り込むことない。この時、作動リンク２７及び連動レバー３０の各中間部分は、連係手段２６を介して互いに係合しているから、それぞれ固定軸２５，２９を支点にして互いに同じ方向へ共働回転し、ラッチ錠３の駆動体ａを解錠方向へ所定量回転させる。また、第２の板状カバー体１８は台座４の内側壁面４ｂに沿って移動する。 Therefore, as shown in FIG. 13, for example, when a portion near the free end 12b of the plate-like cover body 12 of the inner handle 6 is gripped and pushed toward the mounting base 4a side (in the direction of arrow A) of the base 4, for example, the handle is gripped. Alternatively, the index finger f that has been pushed in does not inadvertently enter the outward recess 31 because the plate-like cover body 12 is in the closed state. At this time, since the intermediate portions of the operation link 27 and the interlocking lever 30 are engaged with each other via the linkage means 26, they rotate together in the same direction with the fixed shafts 25 and 29 as fulcrums, respectively. The driving body a of the lock 3 is rotated by a predetermined amount in the unlocking direction. In addition, the second plate-like cover body 18 moves along the inner wall surface 4 b of the pedestal 4.

一方、図１３の押し込んだ状態から図６の初期位置へと戻る際、仮に把持中の指ｆが板状カバー体１２の端部内面に衝突した場合には、該板状カバー体１２は基端部１２ａを支点にしてその自由端１２ｂが戻しバネ１９のバネ力に抗して外方向へ逃げるので、指ｆを板状カバー体１２の自由端とハンドル６の外壁面との間に挟むようなこともない。 On the other hand, when the finger f being gripped collides with the inner surface of the end portion of the plate-like cover body 12 when returning from the pushed-in state in FIG. 13 to the initial position in FIG. Since the free end 12b escapes outward against the spring force of the return spring 19 with the end 12a as a fulcrum, the finger f is sandwiched between the free end of the plate-like cover body 12 and the outer wall surface of the handle 6. There is no such thing.

本発明の要部を構成する連係手段としての２６は、その一方が作動リンク２７の中間部分に突設された係合ピン２６ａであり、その他方が連動レバー３０の中間部分に形成されかつ前記係合ピン２６ａが係合する係合長孔２６ｂであるが、該係合長孔２６ｂは切欠状の係合部分に設計変更することもできる。 One of the linking means 26 constituting the main part of the present invention is an engaging pin 26a projecting from the intermediate portion of the operating link 27, and the other is formed at the intermediate portion of the interlocking lever 30. The engagement long hole 26b engages with the engagement pin 26a. However, the design of the engagement long hole 26b can be changed to a notch-shaped engagement portion.

また、第１固定軸２５及び第２固定軸２９の左右・上下の位置は、プル側ハンドル装置Ｘの連動レバー３０の可動端部（突出端部）３０ａに対して、プッシュ側のハンドル装置の連動レバー３０のそれを、ラッチ錠３側の駆動体ａの受動突起部ｂに対して略同一水平線上に位置付ける、前記駆動体の受動部を同じ方向へ押圧する、両可動端部（突出端部）３０ａ、３０ａのストロークを同じくする、という目的を踏まえて設定することができる。 Further, the left and right and upper and lower positions of the first fixed shaft 25 and the second fixed shaft 29 are set so that the push-side handle device has a movable end (projecting end) 30a of the interlocking lever 30 of the pull-side handle device X. Both movable end portions (protruding ends) for pressing the passive portion of the driving body in the same direction, positioning the interlocking lever 30 on the substantially same horizontal line with respect to the passive protrusion portion b of the driving body a on the latch lock 3 side. Part) 30a and 30a can be set based on the purpose of making the strokes the same.

なお、本発明のハンドル装置のプル式のハンドル６は、一端部が軸支された「揺動型」のみならず、上下の台座側に平行リンク機構や同期機構を備え、プル式のハンドルが前後方向に水平移動する「水平動型」であっても良い。 The pull type handle 6 of the handle device of the present invention is not only a “swing type” whose one end is pivotally supported, but also includes a parallel link mechanism and a synchronization mechanism on the upper and lower pedestal sides, and the pull type handle It may be a “horizontal motion type” that horizontally moves in the front-rear direction.
