Description
本発明は、例えばキャビネット等におけるガラス引戸を、閉止状態に拘束するラッチ装置に関する。 The present invention relates to a latch device that restrains, for example, a glass sliding door in a cabinet or the like in a closed state.
この種の引戸のラッチ装置としては、例えば特許文献１及び２に記載されているものがある。
上記特許文献１に記載されているラッチ装置においては、引戸の下端を案内するガイドレールの側端に、引戸の側端下部に設けた上下方向に操作可能な係止具の下端を突入させることにより、引戸を閉止状態に拘束するようになっており、引戸を開く際には、係止具を上方に移動させる必要がある。 In the latch device described in Patent Document 1, the lower end of the vertically operable locking tool provided at the lower side end of the sliding door is inserted into the side end of the guide rail that guides the lower end of the sliding door. Thus, the sliding door is constrained to the closed state, and when opening the sliding door, it is necessary to move the locking tool upward.
そのため、引戸を開く水平方向の動作と、係止具を解除操作する動作とが９０°異なり、それらを一方向の動作で同時に操作できないため、操作性や使い勝手が悪い。 For this reason, the horizontal movement of opening the sliding door differs from the movement of releasing the locking tool by 90 °, and they cannot be operated simultaneously in one direction, so that the operability and usability are poor.
特許文献２に記載されているラッチ装置は、引戸を開く方向の動作と、ラッチ（ロックプレート）のロック解除方向の動作とがほぼ同方向であるため、操作性がよい。しかし、ラッチは、ばねにより常にレールと係合する方向に付勢されており、ロックを解除して引戸を開閉する際にも、ラッチの係合爪がレールの上面と圧接しながら摺動するため、引戸の開閉抵抗が大きくなったり、摺動音を発したりすることがある。

さらに、把手を操作する際、その側方の固定側の把持片にも指を掛ける必要があるため、操作性が悪い。
Further, the handle (knob) is directly connected to the latch and moves in the left-right direction in conjunction with the vertical rotation of the latch, which makes the operator feel uncomfortable.
Furthermore, when the handle is operated, it is necessary to put a finger on the holding piece on the side of the handle.
本発明は、上記問題点に鑑みてなされたもので、引戸のロックを解除する動作と、引戸を開く動作とを同方向として、同時に行いうるようにし、操作性を向上するとともに、引戸を開閉する際の抵抗を小さくして軽快に開閉しうるようにし、かつ把手にラッチの動きが伝わらないようにすることにより、違和感を解消しうるようにした引戸のラッチ装置を提供することを目的としている。 The present invention has been made in view of the above-described problems. The operation for unlocking the sliding door and the operation for opening the sliding door can be performed simultaneously in the same direction, improving operability and opening and closing the sliding door. The purpose of the present invention is to provide a sliding door latching device that can reduce the resistance at the time of opening and closing lightly and prevent the movement of the latch from being transmitted to the handle, thereby eliminating the uncomfortable feeling.

請求項１記載の発明によれば、把手部材を引戸の開き方向に操作してラッチ作動部材を上昇させると、これと連動してラッチ部材も上昇し、その下端が係止部より離脱して引戸を開くことができる。従って、把手部材を操作してラッチ部材のロックを解除する動作と、引戸を開く動作とが同じ水平方向となり、かつそれらの動作を、把手部材から手を離すことなく連続して同時に行いうるので、操作性が向上する。 According to the first aspect of the present invention, when the latch member is raised by operating the handle member in the sliding door opening direction, the latch member also rises in conjunction with this, and the lower end thereof is detached from the locking portion. The sliding door can be opened. Therefore, the operation of unlocking the latch member by operating the handle member and the operation of opening the sliding door are in the same horizontal direction, and these operations can be performed simultaneously and continuously without releasing the hand from the handle member. , Operability is improved.
また、ラッチ部材は自重により下降して、係止部と係合するようになっており、従来のように、ばねにより係合方向に積極的に付勢していないので、引戸を開閉する際にラッチ部材が開口部の下端部上面に強く圧接しながら摺動することはない。従って、引戸の開閉抵抗が小さくなることにより、それを軽快に開閉しうるとともに、大きな摺動音を発することもない。特に、ラッチ部材が上昇したとき、その下端が開口部の下部上面から離間するようにしてあるので、ラッチ部材の下端を開口部の下部上面から離間させた状態のまま、引戸を開くことができ、摺動音を発したり、開き抵抗が増大したりするのが防止される。 Further, the latch member is lowered by its own weight and is engaged with the locking portion, and is not positively biased in the engaging direction by the spring as in the conventional case, so when opening and closing the sliding door In addition, the latch member does not slide while strongly pressing against the upper surface of the lower end of the opening. Accordingly, when the opening / closing resistance of the sliding door is reduced, it can be opened / closed lightly and no loud sliding noise is generated. In particular, when the latch member is lifted, its lower end is separated from the upper surface of the lower part of the opening, so that the sliding door can be opened with the lower end of the latch member being separated from the upper surface of the lower part of the opening. It is possible to prevent sliding noise and increase in opening resistance.
さらに、把手部材のみに指を掛けて操作しうるので、従来のような固定側の把持片を突設して、これに指を掛ける必要はなく、簡単かつ円滑な操作が可能となるとともに、見栄えもよくなる。 Furthermore, since it is possible to operate by placing a finger only on the handle member, it is not necessary to project a fixed grip piece on the fixed side as in the prior art, and to apply a finger to this, allowing easy and smooth operation, Appearance also improves.
把手部材、ラッチ作動部材及びラッチ部材は、それぞれ別体をなし、かつ互いに直接的に連結されていないので、ラッチ部材の上下方向の動きが、把手部材に伝達されてこれが動くということはなく、操作者に違和感を与えることがない。 Since the handle member, the latch actuating member, and the latch member are separate from each other and are not directly connected to each other, the vertical movement of the latch member is not transmitted to the handle member and does not move. There is no sense of incongruity to the operator.
請求項２記載の発明によれば、把手部材は、引戸の前面の凹部内を左右方向に移動するので、体裁がよくなるとともに、引戸の前方から簡単に取付けることができ、また交換も容易となる。 According to the second aspect of the present invention, since the handle member moves in the left-right direction in the concave portion on the front surface of the sliding door, the appearance is improved and the grip member can be easily attached from the front of the sliding door and can be easily replaced. .
請求項３記載の発明によれば、把手部材に突設した作動軸を、ラッチ作動部材の長孔に嵌合するだけで、それらの部材同士を連動可能に容易に連係することができる。
また、把手部材の左右方向の移動操作に追従して、ラッチ作動部材を確実に昇降させることができる。
According to the third aspect of the present invention, it is possible to easily link the members to each other so as to be interlocked with each other only by fitting the operating shaft protruding from the handle member into the long hole of the latch operating member.
Further, the latch actuating member can be reliably raised and lowered following the movement operation of the handle member in the left-right direction.
請求項４記載の発明によれば、ガイド溝に向かって連結片を押し込むだけで、ラッチ作動部材とラッチ部材とを、上下に相対移動自在に簡単に連係することができ、また着脱も容易である。 According to the fourth aspect of the present invention, the latch actuating member and the latch member can be simply linked so as to be movable relative to each other simply by pushing the connecting piece toward the guide groove, and can be easily attached and detached. is there.
請求項５記載の発明によれば、ラッチ作動部材が上昇させられ、ラッチ部材の連結片がガイド溝の下端まで相対移動すると、ストッパ段部に自動的に当接して、ラッチ部材が上昇するので、複雑な連動手段を設ける必要はなく、コスト低減が図れる。 According to the fifth aspect of the present invention, when the latch actuating member is raised and the connecting piece of the latch member relatively moves to the lower end of the guide groove, the latch member is automatically brought into contact with the stopper stepped portion. in, it is not necessary to provide a complicated interlocking means, cost reduction can be achieved.
請求項６記載の発明によれば、万一ラッチ部材が自重により下降しないときでも、補助付勢手段により強制的に下降させられるので、ラッチ部材を係止部に確実に係止することができる。 According to the sixth aspect of the present invention, even if the latch member is not lowered by its own weight, it can be forcibly lowered by the auxiliary biasing means, so that the latch member can be reliably locked to the locking portion. .
また、ラッチ装置の各部材を上下反対向きとすると、ラッチ部材は補助付勢手段により上向きに移動させられるので、引戸の上部にラッチ装置を取付けても正常に機能させることができる。 Further, if each member of the latch device is turned upside down, the latch member is moved upward by the auxiliary biasing means, so that it can function normally even if the latch device is attached to the upper part of the sliding door.
請求項７記載の発明によれば、圧縮ばね等の補助付勢手段を別途設ける必要がないので、部品点数や組付工数が削減される。 According to the seventh aspect of the present invention, it is not necessary to separately provide auxiliary biasing means such as a compression spring, so that the number of parts and assembly man-hours are reduced.
請求項８記載の発明によれば、ラッチ部材は、ぐらつくことなく安定して上下動することができる。 According to the eighth aspect of the present invention, the latch member can move up and down stably without wobbling.

合成樹脂により形成されたラッチ部材(15)は、横桟(７)内を上下に摺動可能な前後寸法を有する縦長のブロック状をなし、左方（内方）の側面における前端縁と後端縁とには、それぞれ図３及び図４に示すように、左側方（内側方）を向く１個の連結片(34)と、上下２個の連結片(35)(35)とが、正面視において前部の連結片(34)が後部の上下の連結片(35)との間に位置するように一体的に突設されている。 The latch member (15) made of synthetic resin has a longitudinal block shape with front and rear dimensions that can slide up and down in the horizontal rail (7), and the front edge and rear edge on the left (inward) side surface. As shown in FIG. 3 and FIG. 4 respectively, one end of the connecting piece (34) facing the left side (inner side) and two upper and lower connecting pieces (35) and (35) The front connecting piece (34) is integrally projected so as to be positioned between the upper and lower connecting pieces (35) in the front view.
前部の連結片(34)の後面と、後部の上下の連結片(35)の前面との中間部には、上記ラッチ作動部材(14)におけるガイド片(30)の前後のガイド溝(29)(29)に、上下方向に摺動自在に係合される係合突部(36)が突設されている。この係合時において、前部の連結片(34)の下端は、ラッチ作動部材(14)の前部のストッパ段部(31)の上面に、後部の下側の連結片(35)の下端は、同じく後部のストッパ段部(32)の上面に、それぞれラッチ部材(15)の自重により当接し、ラッチ部材(15)の下方への最大移動量が規制されるようになっている。 In the middle part between the rear surface of the front connecting piece (34) and the front surface of the upper and lower connecting pieces (35), the guide grooves (29) on the front and rear of the guide piece (30) in the latch operating member (14) are provided. ) (29) is provided with an engaging protrusion (36) that is slidably engaged in the vertical direction. At the time of this engagement, the lower end of the front connection piece (34) is on the upper surface of the front stopper step (31) of the latch actuating member (14) and the lower end of the rear lower connection piece (35). Similarly, the upper surface of the rear stopper step (32) is brought into contact with the own weight of the latch member (15), and the maximum downward movement amount of the latch member (15) is regulated.
この当接時において、ラッチ部材(15)の下端部は、ラッチ作動部材(14)の下端よりも所要寸法下方に突出し、ガイドレール(９)の外側端の切欠係止部(9a)と係合しうるようになっている（図２、図５参照）。また、この際、ラッチ部材(15)の上面中央に、弾性付勢片(28)の先端下面が軽く当接するようになっている。 At the time of this contact, the lower end of the latch member (15) protrudes below the required dimension from the lower end of the latch actuating member (14) and engages with the notch locking portion (9a) at the outer end of the guide rail (9). (See FIGS. 2 and 5). At this time, the lower surface of the tip of the elastic urging piece (28) comes into light contact with the center of the upper surface of the latch member (15).
ラッチ部材(15)の前後両面のやや上方寄りの中央部には、上下２個の方形をなす凹部(37)と、上下方向を向くガイド溝(38)とが、互いに連通するようにして形成されている。 In the middle part of the latch member (15) slightly above and below the front and rear surfaces, a concave part (37) having two upper and lower squares and a guide groove (38) facing upward and downward are formed so as to communicate with each other. Has been.
前後のガイド溝(38)は、図３及び図４に示すように、横桟(７)における前面板(7a)と後面板(7b)との外側端部内面の対向面に突設された上下方向を向くガイド突条(39)に、上下に摺動可能に嵌合されるようになっている。なお、上記とは反対に、ガイド溝(38)を横桟(７)側に、ガイド突条(39)をラッチ部材(15)側に設けてもよい。 As shown in FIGS. 3 and 4, the front and rear guide grooves (38) are provided so as to project on the opposing surfaces of the inner surfaces of the outer end portions of the front plate (7 a) and the rear plate (7 b) in the cross rail (7). The guide ridge (39) facing in the vertical direction is slidably fitted in the vertical direction. In contrast to the above, the guide groove (38) may be provided on the side rail (7) side, and the guide protrusion (39) may be provided on the latch member (15) side.
次に、上記ラッチ装置(４)における各部材の組付け手順について説明する。
まず、ラッチ作動部材(14)に、ラッチ部材(15)を、上述した要領で上下に摺動可能に組付けたのち、それらを、引戸本体(５)取付前の横桟(７)内に上方から挿入し、ラッチ部材(15)の前後のガイド溝(38)を、前面板(7a)と後面板(7b)のガイド突条(39)に嵌合する。
Next, the assembly procedure of each member in the latch device (4) will be described.
First, the latch member (15) is assembled to the latch actuating member (14) so as to be slidable in the vertical direction as described above, and then they are placed in the cross rail (7) before the sliding door body (5) is mounted. Inserted from above, the front and rear guide grooves (38) of the latch member (15) are fitted into the guide protrusions (39) of the front plate (7a) and the rear plate (7b).
ついで、横桟(７)の前面板(7a)に形成した操作枠(21)内に、把手部材(12)を挿入し、その上下の係止片(17)(18)を、前面板(7a)の上下の開口(22)(23)に係止することにより、抜け止めしつつ、左右方向に摺動可能に取付ける。かつ同時に、把手部材(12)の上下の作動軸(19)を、ラッチ作動部材(14)における斜め上下方向を向く作動長孔(33)と、後面板(7b)の左右方向を向く上下のガイド孔(24)とに摺動可能に嵌合する。 Next, the handle member (12) is inserted into the operation frame (21) formed on the front plate (7a) of the horizontal rail (7), and the upper and lower locking pieces (17) and (18) are inserted into the front plate ( 7a) It is attached to the upper and lower openings (22) and (23) so as to be slidable in the left-right direction while preventing it from coming off. At the same time, the upper and lower operating shafts (19) of the handle member (12) are connected to the upper and lower operating holes (33) facing the diagonally up and down direction of the latch operating member (14) and the left and right sides of the rear plate (7b). The guide hole (24) is slidably fitted.
ついで、ねじりコイルばね(13)を、図２、図３及び図５に示すように、把手部材(12)の内側方（左側方）において、前面板(7a)と後面板(7b)との対向面のいずれか一方に突設した支持軸(40)に嵌合したのち、内方の上方を向く足片(13a)における上端の逆Ｕ字状の引掛け部(13b)を、前面板(7a)と後面板(7b)の対向面に形成された上下方向を向く補強リブ(41)の上端部に、上方より掛止するとともに、外方の上方を向く足片(13c)の上端部を、把手部材(12)の後面に突設したばね受片(20)の内側面（左側面）に、付勢力を付与した状態で圧接させる。 Next, as shown in FIGS. 2, 3 and 5, the torsion coil spring (13) is moved between the front plate (7a) and the rear plate (7b) on the inner side (left side) of the handle member (12). After fitting the support shaft (40) projecting on either side of the opposing surface, the upper U-shaped hook (13b) on the top (13a) facing inward (7a) and the rear plate (7b) are opposed to the upper end of the reinforcing rib (41) facing upwards and formed on the opposing surface of the rear plate (7b), and the upper end of the foot piece (13c) facing upward from the upper side. The portion is brought into pressure contact with the inner side surface (left side surface) of the spring receiving piece (20) projecting from the rear surface of the handle member (12) in a state where an urging force is applied.
これにより、各部材の組付けは完了し、把手部材(12)は、ねじりコイルばね(13)の付勢力により、操作枠(21)内の右端側に位置させられるとともに、上下の作動軸(19)が、後面板(7b)におけるガイド孔(24)の右端及びラッチ作動部材(14)の作動長孔(33)の上端に位置することにより、ラッチ作動部材(14)は、下限位置に強制的に移動させられる。 Thus, the assembly of each member is completed, and the handle member (12) is positioned on the right end side in the operation frame (21) by the urging force of the torsion coil spring (13), and the upper and lower operation shafts ( 19) is positioned at the right end of the guide hole (24) in the rear plate (7b) and the upper end of the operation long hole (33) of the latch operation member (14), so that the latch operation member (14) is in the lower limit position. Forced to move.
また、ラッチ作動部材(14)が下限に位置することにより、これに上下に摺動自在に連結されているラッチ部材(15)も、下限位置まで自重により移動可能となる。 In addition, since the latch operating member (14) is positioned at the lower limit, the latch member (15) that is slidably connected to the latch operating member (15) can also move to the lower limit position by its own weight.
次に、図５〜図７の概略正面図を参照して、上記ラッチ装置(４)の作用を説明する。 Next, the operation of the latch device (4) will be described with reference to the schematic front views of FIGS.
図５に示すように、右側のガラス引戸(２)が閉じられ、その下部の横桟(７)の右側面（外側面）が上部キャビネット(３)の側枠(42)と当接している状態において、把手部材(12)を操作していないときには、把手部材(12)は、ねじりコイルばね(13)の付勢力により、横桟(７)の操作枠(21)内の右限位置に移動させられ、それに突設した上下の作動軸(19)は、ガイド孔(24)の右端及び作動長孔(33)の上端に位置する。 As shown in FIG. 5, the right glass sliding door (2) is closed, and the right side surface (outer side surface) of the lower horizontal rail (7) is in contact with the side frame (42) of the upper cabinet (3). In this state, when the handle member (12) is not operated, the handle member (12) is moved to the right limit position in the operation frame (21) of the horizontal beam (7) by the urging force of the torsion coil spring (13). The upper and lower operating shafts (19) that are moved and project from the upper and lower operating shafts are positioned at the right end of the guide hole (24) and the upper end of the operating long hole (33).
これにより、ラッチ作動部材(14)は下限位置まで下降するとともに、それに上下に摺動自在に連結されているラッチ部材(15)も、前後の連結片(34)（一方のみ図示）の下端が前後のストッパ段部(31)（一方のみ図示）と当接する下限位置まで、自重もしくは弾性付勢片(28)の付勢力により下降する。その結果、ラッチ部材(15)の下端部が下方に突出し、ガイドレール(９)における外側端の切欠係止部(9a)と係合することにより、ガラス引戸(２)はロックされ、閉止状態に拘束される。 As a result, the latch actuating member (14) is lowered to the lower limit position, and the latch member (15) that is slidably connected to the upper and lower sides of the latch actuating member (14) has the lower ends of the front and rear connecting pieces (34) (only one shown). It is lowered by its own weight or the urging force of the elastic urging piece (28) to the lower limit position where it comes into contact with the front and rear stopper steps (31) (only one is shown). As a result, the lower end portion of the latch member (15) protrudes downward and engages with the notch engaging portion (9a) at the outer end of the guide rail (9), so that the glass sliding door (2) is locked and closed. Restrained by
この状態において、把手部材(12)に手を掛け、これを、ねじりコイルばね(13)の付勢力に抗して左限まで移動させると、図６に示すように、上下の作動軸(19)が、ガイド孔(24)の左端に移動するのに伴なって、両作動軸(19)は、上下の作動長孔(33)における上昇用傾斜カム面(33a)を強く押圧しながら、相対的に下端まで移動する。これにより、ラッチ作動部材(14)は上昇させられ、それと連動して、ストッパ段部(31)と当接して下限に位置しているラッチ部材(15)も上昇する。 In this state, when the handle member (12) is held and moved to the left limit against the urging force of the torsion coil spring (13), as shown in FIG. ) Is moved to the left end of the guide hole (24), both operating shafts (19) strongly press the rising inclined cam surface (33a) in the upper and lower operating long holes (33), Move to the lower end relatively. As a result, the latch actuating member (14) is raised, and in conjunction therewith, the latch member (15) which is in contact with the stopper step (31) and located at the lower limit is also raised.
その結果、ラッチ部材(15)の下端部が、ガイドレール(９)の切欠係止部(9a)より離脱して上限まで移動することにより、ロックが解除され、ガラス引戸(２)を開くことができる。この際、ねじりコイルばね(13)のばね力を、ガラス引戸(２)の開き抵抗よりも小さく設定すれば、把手部材(12)は右限の定位置に復帰することがないので、ラッチ部材(15)の下端をガイドレール(９)の上面から離間させた状態のまま、ガラス引戸(２)を開くことができ、摺動音を発したり、開き抵抗が増大したりするのが防止される。 As a result, the lower end of the latch member (15) is released from the notch engaging portion (9a) of the guide rail (9) and moved to the upper limit, so that the lock is released and the glass sliding door (2) is opened. Can do. At this time, if the spring force of the torsion coil spring (13) is set to be smaller than the opening resistance of the glass sliding door (2), the handle member (12) will not return to the right limit position. The glass sliding door (2) can be opened while the lower end of (15) is separated from the upper surface of the guide rail (9), and it is possible to prevent sliding noise and increase in opening resistance. The
一方、ねじりコイルばね(13)のばね力を、ガラス引戸(２)の開き抵抗より大きく設定すると、図７に示すように、ロックが解除されてガラス引戸(２)を開き始めた直後に、把手部材(12)は右限の定位置まで移動する。 On the other hand, when the spring force of the torsion coil spring (13) is set larger than the opening resistance of the glass sliding door (2), as shown in FIG. 7, immediately after the lock is released and the glass sliding door (2) starts to open, The handle member (12) moves to the right limit position.
すると、上下の作動軸(19)が、ガイド孔(24)の右端に移動するのに伴なって、作動長孔(33)における下降用傾斜カム面(33b)が作動軸(19)により強く押圧され、ラッチ作動部材(14)は下降させられる。その結果、ラッチ部材(15)も自重により下降し、その下端がガイドレール(９)の上面と当接した時点で、ラッチ作動部材(14)の弾性付勢片(28)を上方に撓ませながら相対的に上方に移動する。 Then, as the upper and lower operating shafts (19) move to the right end of the guide hole (24), the descending inclined cam surface (33b) in the operating long hole (33) is stronger than the operating shaft (19). When pressed, the latch actuating member (14) is lowered. As a result, the latch member (15) is also lowered by its own weight, and when the lower end of the latch member (15) comes into contact with the upper surface of the guide rail (9), the elastic biasing piece (28) of the latch operating member (14) is bent upward. While moving relatively upward.
この状態で、把手部材(12)を左方に操作することにより、これを右限の定位置に位置させたままでガラス引戸(２)を開くことができる。また、把手部材(12)を右方に操作してガラス引戸(２)を閉じる際も、図７と同様、把手部材(12)は右限の定位置に保持され、ガラス引戸(２)が閉止される間際に、ラッチ部材(15)がその自重と弾性付勢片(28)との付勢力により、ガイドレール(９)の切欠係止部(9a)に自動的に係合してロックされる。 By operating the handle member (12) to the left in this state, the glass sliding door (2) can be opened with the handle member (12) being positioned at the right limit position. Also, when the handle member (12) is operated to the right to close the glass sliding door (2), the handle member (12) is held in the right limit position as in FIG. The latch member (15) is automatically engaged with the notch engaging portion (9a) of the guide rail (9) by the urging force of its own weight and the elastic urging piece (28) when it is closed. Is done.
なお、上記ガラス引戸(２)の開閉時には、ラッチ部材(15)の下端がガイドレール(９)の上面と摺接することとなるが、弾性付勢片(28)の下向き付勢力を極く小さいものとすることにより、摺動音や摺動抵抗を最小限に抑えることができる。 When the glass sliding door (2) is opened and closed, the lower end of the latch member (15) is in sliding contact with the upper surface of the guide rail (9), but the downward biasing force of the elastic biasing piece (28) is extremely small. By using this, sliding noise and sliding resistance can be minimized.
以上説明したように、上記実施形態のラッチ装置においては、把手部材(12)を操作してラッチ部材(15)によるロックを解除する動作と、ガラス引戸(２)を開く動作とが、同じ水平方向であり、かつそれらの動作を、把手部材(12)から手を離すことなく、連続して同時に行うことができるので、操作性が向上する。 As described above, in the latch device of the above embodiment, the operation of releasing the lock by the latch member (15) by operating the handle member (12) and the operation of opening the glass sliding door (2) are the same horizontal. The operation can be performed continuously and simultaneously without removing the hand from the handle member (12).
また、従来のように、把手部材(12)を操作する際に、固定側の把持片にも指を掛ける必要がないので、円滑な操作が可能となり、かつ固定側の把持片を突設する必要もないので、見栄えがよくなる。 Further, unlike the conventional case, when operating the handle member (12), it is not necessary to put a finger on the fixed-side grip piece, so that smooth operation is possible and the fixed-side grip piece is projected. Since it is not necessary, it looks better.
さらに、ラッチ部材(15)は、実質的にその自重によりガイドレール(９)と係合するようになっており、従来のように、ばねにより係合方向に積極的に付勢していないので、ラッチ部材(15)の下端がガイドレール(９)の上面と強く圧接しながら摺動することはなく、ガラス引戸(２)の開閉抵抗が小さくなることにより、それを軽快に開閉することができる。また、大きな摺動音を発したりすることもない。 Further, the latch member (15) is substantially engaged with the guide rail (9) by its own weight, and is not positively biased in the engaging direction by the spring as in the conventional case. The lower end of the latch member (15) does not slide while strongly pressing against the upper surface of the guide rail (9), and the opening and closing resistance of the glass sliding door (2) is reduced, so that it can be opened and closed easily. it can. In addition, no loud sliding noise is generated.
ラッチ装置を構成している把手部材(12)、ラッチ作動部材(14)及びラッチ部材(15)は、それぞれ別体をなし、かつ互いに直接的に連結されていないので、ラッチ部材(15)の上下方向の動きが、把手部材(12)に伝達されてこれが動くということはなく、操作者に違和感を与えることがない。 The handle member (12), the latch actuating member (14), and the latch member (15) constituting the latch device are separate from each other and are not directly connected to each other, so that the latch member (15) The movement in the vertical direction is not transmitted to the handle member (12) and does not move, and the operator does not feel uncomfortable.
本発明は、上記実施形態に限定されるものでない。
上述したように、ラッチ部材(15)は、ラッチ作動部材(14)に上下に移動自在に連結され、かつ自重により下降してガイドレール(９)と係合するようになっているため、弾性付勢片(28)は省略することもある。
The present invention is not limited to the above embodiment.
As described above, the latch member (15) is connected to the latch operating member (14) so as to be movable up and down, and is lowered by its own weight to engage with the guide rail (9). The biasing piece (28) may be omitted.
上記実施形態のようなラッチ装置を、上下反対向きとして上部の横桟(６)に組付け、ラッチ部材(15)を、上方のガイドレールの側端又は上部横枠(11)の側端部下面に設けた係止孔等に係合して、ガラス引戸(２)をロックしうるようにすることもできる。この際には、ラッチ部材(15)を上方に移動させる必要があるため、上記弾性付勢片(28)のような上向付勢手段を設ければよい。 The latch device as in the above embodiment is assembled to the upper horizontal rail (6) in the upside down direction, and the latch member (15) is attached to the side end of the upper guide rail or the upper horizontal frame (11). The glass sliding door (2) can be locked by engaging with a locking hole or the like provided on the lower surface. At this time, since it is necessary to move the latch member (15) upward, an upward biasing means such as the elastic biasing piece (28) may be provided.
上記実施形態では、ラッチ作動部材(14)にラッチ部材(15)を上下に摺動自在に連結する手段に、ガイド溝(29)と連結片(34)(35)を用いているが、ラッチ作動部材(14)とラッチ部材(15)との対向部に、互いに上下に摺動自在に嵌合し合う軸状部と筒状部等を設けるなどしてもよい。 In the above embodiment, the guide groove (29) and the connecting pieces (34) (35) are used as means for slidably connecting the latch member (15) to the latch operating member (14). A shaft portion, a cylindrical portion, and the like that are slidably fitted to each other up and down may be provided on the facing portion between the operating member (14) and the latch member (15).
また、上記実施形態では、把手部材(12)とラッチ作動部材(14)との連動手段を、把手部材(12)に設けた上下の作動軸(19)と、ラッチ作動部材(14)に設けた斜め上下方向を向く作動長孔(33)とからなるものとし、それらを嵌合することにより、ラッチ作動部材(14)を上下に移動させるようにしているが、作動長孔(33)の代わりに、斜め上下方向を向くカム板を突設し、その下面の傾斜カム面を、ラッチ作動部材(14)の自重により作動軸(19)の上部外周面に常時摺接するようにしてもよい。 In the above embodiment, the interlocking means between the handle member (12) and the latch operating member (14) is provided on the upper and lower operating shafts (19) provided on the handle member (12) and the latch operating member (14). It is assumed that the latch operating member (14) is moved up and down by fitting them, and the operating slot (33) of the operating slot (33) Instead, a cam plate facing obliquely up and down may be provided so that the inclined cam surface on the lower surface thereof is always in sliding contact with the upper outer peripheral surface of the operating shaft (19) by the weight of the latch operating member (14). .
このようにしても、作動軸(19)が左右方向に移動すると、その動きに連動してラッチ作動部材(14)が上下動するようになる。なお、この際は、作動軸(19)の動きに追従しうるように、ラッチ作動部材(14)の重量を若干大とするのがよい。 Even in this case, when the operating shaft (19) moves in the left-right direction, the latch operating member (14) moves up and down in conjunction with the movement. In this case, the weight of the latch operating member (14) is preferably slightly increased so that the movement of the operating shaft (19) can be followed.
ラッチ部材(15)の下端を係合させる係止手段は、ガイドレール(９)又は下部横枠(８)の側端部上面に形成された係止孔等としてもよい。
本発明は、上記のようなガラス引戸(２)以外の引戸にも適用しうることは言うまでもない。
The locking means for engaging the lower end of the latch member (15) may be a locking hole or the like formed on the upper surface of the side end portion of the guide rail (9) or the lower horizontal frame (8).
It goes without saying that the present invention can be applied to sliding doors other than the glass sliding door (2) as described above.
