Description
【0001】[0001]
本考案は引き戸用錠に関するものであり、より詳しくは、引き戸用のチューブ ラ型の鎌錠であって、シンプルな構成で部品点数を少なくし、小型で取付けにス ペースを取らぬと共に、スムーズに作動し、かつ受け金具との取付け位置に多少 のズレが有っても、確実に掛止できるようにしたことを特徴とするものである。 The present invention relates to a lock for a sliding door, and more particularly, a tube for a sliding door. It is a la-type sickle lock, has a simple structure with a small number of parts, and is compact and easy to install. Not only does it keep pace, but it operates smoothly, and the mounting position with the bracket is somewhat The feature is that even if there is a deviation, it can be locked securely.
【0002】[0002]
引き戸用錠、即ち操作部材により錠ケース内のハブが回動して、鎌部材を前方 へ突出させて戸枠体の受け金具に掛止させ、また後退させて掛止が外れるように した錠については、従来より各種のものが存在する。そして、本考案と同じチュ ーブラ型鎌錠としては、例えば特開平10−25937号公報に記載のものがあ る。 その構成の要旨は、特許請求の範囲の請求項1に記載の如く、「サムターンま たはドアハンドルに連係する回動カムと、該カムに連係するリンクと、該リンク に回動可能に連結し、かつ錠ケースに出没可能に装着した鎌とを備えた引き戸錠 において、リンクと鎌とを錠ケースに略平行移動可能に収容し、錠ケースの前部 に鎌と係合可能な係合部を設け、該係合部と鎌との係合を介して鎌を回動可能に した引き戸錠」である。 The sliding door lock, that is, the operating member rotates the hub in the lock case to move the sickle member forward. So that it can be released from the door frame by fitting it to the receiving bracket of the door frame, and by retracting it. There are various types of conventional locks. And the same tu As the bra-type sickle lock, for example, one described in JP-A-10-25937 is available. It The gist of the configuration is, as described in claim 1 of the claims, "a thumb turn or Or a rotation cam linked to the door handle, a link linked to the cam, and the link Sliding lock with a sickle that is rotatably connected to the , The link and the sickle are housed in the lock case so that they can move substantially parallel to each other, and The sickle can be engaged with the sickle, and the sickle can be rotated through the engagement between the sickle and the sickle. It is a sliding door lock.
【0003】 その実施例としては、同公報の図1乃至図8に示されており、その1は、回動 カムの回動によりこれと連結したリンクを前方へ押し、該リンク前端部のピンに 回動可能に枢着された鎌も前方へ押され、該鎌の中央下部の斜状のガイド面が、 フロント板中央の通挿穴の開口縁部に係合して押し上げられることで、該鎌が上 記ピンを支点に上向きに回動して、先端の係止爪が開口部の内側縁部と係合する ようにしてある。 またその2は、回動カムの回動によりこれと連結したリンクを前方へ押し、該 リンク前端部のピンに回動可能に枢着された鎌も前方へ押され、該鎌の後端上位 置の凸部が錠ケース前部寄りのストッパーピンと係合して、該鎌は上向きへの回 動が促され、かつ下端後部の凸部が錠ケースの前端部のストッパーに係合して、 該鎌が回動し先端の係止爪が開口部の内側縁部と係合するようにしてある。[0003] An example thereof is shown in FIGS. 1 to 8 of the publication, the first of which is rotation. Rotate the cam to push the link connected to it forward to the pin at the front end of the link. The sickle pivotally attached is also pushed forward, and the oblique guide surface at the lower center of the sickle By engaging with the opening edge of the insertion hole in the center of the front plate and pushing it up, the sickle is raised. Rotate upwards with the pin as a fulcrum, and the locking claw at the tip engages with the inner edge of the opening. Is done. In addition, No. 2 pushes the link connected to the rotation cam forward by the rotation of the rotation cam, The sickle pivotally attached to the pin at the front end of the link is also pushed forward, and the upper end of the rear end of the sickle is pushed forward. The convex part of the table engages with the stopper pin near the front part of the lock case, and the sickle rotates upward. Movement is promoted, and the convex portion at the rear end of the lower end engages with the stopper at the front end of the lock case, The sickle is rotated so that the locking claw at the tip engages with the inner edge of the opening.
【0004】[0004]
ところで、上記公報に記載の引き戸錠は、簡素化された構成とはいうものの、 回動カム(本願考案ではハブという)と鎌(本願考案では鎌部材という)との間 を連結するリンクが不可欠な部品であるし、また回動カムの構造も複雑な形状を 必要としており、それが材料費や製造コストのアップに影響している。 また鎌の作動状態は、回動カムの回動でリンクを介して鎌が前進し、錠ケース の前部で鎌中央下部の斜状のガイド面がフロント板中央の通挿穴の開口縁部に係 合して押し上げられ、または該鎌後端上位置の凸部がストッパーピンに係合し、 かつ下端後部の凸部がストッパーに係合して押し上げられるようになっている。 By the way, although the sliding door lock described in the above publication has a simplified structure, Between the rotating cam (called the hub in the present invention) and the sickle (called the sickle member in the present invention) The link that connects the two is an indispensable part, and the structure of the rotating cam has a complicated shape. It is necessary, which affects the increase of material cost and manufacturing cost. When the sickle is operating, the sickle moves forward through the link by the rotation of the rotation cam, and the lock case The slanted guide surface in the lower center of the sickle on the front part of the Are pushed up together, or the convex portion on the rear end of the sickle engages with the stopper pin, Moreover, the convex portion at the rear portion of the lower end engages with the stopper and is pushed up.
【0005】 そのため、鎌の前進移動が必ずしも常に滑らかに行われるとは限らないし、ま たその回動も斜状のガイド面が通挿穴の開口縁部に係合するだけは、常にスムー ズに回動するとは限らない。また該鎌後端上位置の凸部がストッパーピンに、か つ下端後部の凸部がストッパーに各々係合しても、それだけでは鎌の回動がスム ーズに行われるとも言いがたく、鎌の作動状態でトラブルが生じないとは限らな い。 さらに、鎌は後端をリンクに可回動に枢支されているから、錠ケース内でリン クを介する分だけ鎌の全長が短くなっている。そのため、鎌先端の係止爪から軸 支点までの距離が短く、鎌が支点を中心に回動した際に先端の係止爪の上下動幅 は小さいものであり、例えばこの錠と受け金具との間で取付け位置に誤差がある 場合には、係止爪が受け金具の内側縁部と係合できないことがある。[0005] Therefore, the forward movement of the sickle is not always smooth. Even if the sword is rotated, only the slanted guide surface engages with the opening edge of the insertion hole to ensure smooth movement. It does not always rotate to the right. Also, the convex part on the rear end of the sickle should be Even if the projections at the rear of the lower end engage the stoppers, the sickle's rotation will be smooth. It is hard to say that it will be carried out at any time, and it does not mean that trouble does not occur in the working state of the sickle. Yes. Furthermore, since the sickle is pivotally supported on the link at the rear end, it is linked in the lock case. The total length of the sickle is shortened by the length of the sickle. Therefore, from the locking claw at the tip of the sickle to the shaft The distance to the fulcrum is short, and the vertical movement width of the locking claw at the tip when the sickle rotates around the fulcrum Is small, for example, there is an error in the mounting position between this lock and the bracket In some cases, the locking claw may not be able to engage with the inner edge portion of the receiving fitting.
【0006】 しかも上記のものは、鎌が受け金具に掛止された施錠状態で、引き戸が無理や りに開けられようとした場合に、その外力はこの錠内で鎌からピン・リンク・回 動カム等に作用するので、各部の強度が問題となり、信頼性にやや難があるので は無いか、等の問題点があった。 本考案は引き戸用のチューブラ型鎌錠において、従来のものがもつ上記問題点 の解決を課題としたものである。即ち本考案の目的は、シンプルな構成で部品点 数を一層少なくしてコストダウンを図り、小型で取付けにスペースを取らぬと共 に強度的にも優れており、また作動が常に正確・スムーズに行われ、かつ受け金 具の取付け位置に誤差が有っても、十分に対応して掛止が確実に行われて施錠さ れるようにした、引き戸用錠を提供することにある。[0006] Moreover, the above is a locked state where the sickle is hooked on the receiving metal, and the sliding door is impossible. When it is attempted to be opened, the external force from the sickle will be pin, link, and turn inside this lock. Since it acts on the dynamic cam etc., the strength of each part becomes a problem and reliability is somewhat difficult. There was a problem such as whether there is no. The present invention is a tubular type sickle lock for a sliding door, and has the above-mentioned problems of the conventional one. The problem is to solve. That is, the purpose of the present invention is to simplify the parts The number is further reduced to reduce costs, and it is compact and does not take up space for installation. It has excellent strength, and the operation is always accurate and smooth, and the receiving Even if there is an error in the mounting position of the tool, it can be locked properly and locked securely. The purpose of the present invention is to provide a lock for sliding doors.

【0014】 上記の取付け時に、引き戸16や操作部材の種類により、バックセットが大き いため第1の考案の引き戸用錠が取付けられない場合は、上記第2の考案の引き 戸用錠を取り付ければよい。 上記本考案の引き戸用錠の作動状態は、次のようになる。まず、引き戸1を閉 じて施錠する場合には、鎌部材8が錠ケース1内に没入した状態(例えば図1参 照)で引き戸16を閉じた後に、ツマミやレバーハンドル等の操作部材を、施錠 方向へ回転させればよい。操作部材の角軸18を介して錠ケース1内のハブ5が 回動(図示例では右回りに回動)し、上記第1の考案の引き戸用錠では鎌部材8 後部寄りの連結用ピン12を介して、また上記第2の考案の引き戸用錠では第2 の連結用ピン12と補助板14を介して、鎌部材8が前方(図示例では左方向) へ押されることになる。[0014] When installing the above, depending on the type of sliding door 16 and operating members, the back set is large. Therefore, when the sliding door lock of the first invention cannot be attached, the pulling lock of the second invention can be installed. Just install a door lock. The operating state of the sliding door lock of the present invention is as follows. First, close the sliding door 1 When locking the lock, the sickle member 8 is immersed in the lock case 1 (see, for example, FIG. 1). After closing the sliding door 16 with the light, lock the operating members such as knobs and lever handles. Rotate in the direction. The hub 5 in the lock case 1 is connected via the angular axis 18 of the operating member. It rotates (clockwise in the illustrated example), and in the sliding door lock of the first invention, the sickle member 8 is rotated. Through the connecting pin 12 near the rear portion, and in the sliding door lock of the second invention, the second The sickle member 8 is forward (in the illustrated example, leftward) via the connecting pin 12 and the auxiliary plate 14. Will be pushed to.
【0015】 上記いずれの場合にも、鎌部材8の横長状部10中央寄りに横設したガイド用 ピン11が、錠ケース1の両側板部3内面に形成したガイド用長溝部7に係合し ているので、鎌部材8は該長溝部7に沿ってまず前方へ直進移動する。この前方 への移動により、鎌部材8先端の鉤形状部9は、前板2およびフロント板31か ら前方へ突出して、戸枠体19に設けてある受け金具20内へ係合する(例えば 図2参照)。 続いて上記鎌部材8がもう少し前方へ移動することにより、ガイド用ピン11 はガイド用長溝部7前部寄りの湾曲状部17に沿って上方または下方(図示例で は上方)へ移動するとともに、連結用ピン12もガイド用長溝部7の中央寄り位 置へ移動してくる。そのため、第1・第2の考案の引き戸用錠の各鎌部材8は、 横長状部10が連結用ピン12を支点として上方または下方(図示例では上方) へ回動し、先端の鉤形長部9も上方または下方(図示例では上方)へ回動するか ら、該鉤形状部9が受け金具20内で掛止部材21に掛止されて施錠状態となる (例えば図3,図10参照)。[0015] In any of the above cases, for a guide that is horizontally provided near the center of the horizontally long portion 10 of the sickle member 8. The pin 11 engages with the long guide groove 7 formed on the inner surface of the side plate 3 of the lock case 1. Therefore, the sickle member 8 first moves straight forward along the long groove portion 7. This ahead The hook-shaped part 9 at the tip of the sickle member 8 is moved to the front plate 2 and the front plate 31. To the front and engages into the receiving metal fitting 20 provided on the door frame body 19 (for example, See FIG. 2). Then, the sickle member 8 is moved a little further forward, so that the guide pin 11 Is above or below (in the illustrated example) along the curved portion 17 near the front of the long groove portion 7 for guide. Moves upward), and the connecting pin 12 is also closer to the center of the guide long groove portion 7. Move to the table. Therefore, each sickle member 8 of the sliding door lock of the first and second inventions, The horizontally long portion 10 is upward or downward (upper in the illustrated example) with the connecting pin 12 as a fulcrum. And the hook-shaped elongated portion 9 at the tip also rotates upward or downward (upward in the illustrated example). Then, the hook-shaped portion 9 is locked by the locking member 21 in the receiving metal fitting 20 to be locked. (See, for example, FIGS. 3 and 10).
【0016】 上記の場合に、第1・第2の考案の引き戸用錠のいずれの鎌部材8も、従来の 引き戸用錠と異なりハブ5と鎌部材8間にリンクを用いておらず、横長状部10 によって該鎌部材8自体が後方へ長くなっており、かつその後部寄りの連結用ピ ン12を支点に回動可能となっている。そのため、鎌部材8は先端の鉤形状部9 が上記の如く回動した際の上下動幅は、仮に従来のものの回動角と同じであって も、鎌部材8が長い分だけ大幅に拡大している。これにより、この引き戸用錠と 受け金具20の取付け位置に誤差があっても、鎌部材8先端の鉤形状部9は受け 金具20の掛止部材21に余裕をもって掛止される(上記図3,図10参照)。[0016] In the above case, both sickle members 8 of the sliding door locks of the first and second inventions are Unlike the sliding door lock, no link is used between the hub 5 and the sickle member 8, and the horizontally long portion 10 Due to this, the sickle member 8 itself is elongated rearward, and the connecting pin near the rear part is formed. It can be rotated around the fulcrum 12. Therefore, the sickle member 8 has a hook-shaped portion 9 at the tip. The vertical movement width when the above is rotated is the same as the conventional rotation angle. However, the length of the sickle member 8 is greatly expanded. As a result, with this sliding door lock Even if there is an error in the mounting position of the bracket 20, the hook-shaped part 9 at the tip of the sickle member 8 is The fitting member 21 of the metal fitting 20 is fitted with a sufficient margin (see FIGS. 3 and 10 above).
【0017】 上記の鎌部材8の回動に関して、第2の考案の引き戸用錠では鎌部材8の横長 状部10の後部に補助板14を連結してあるが、従来のリンクを用いたものと異 なり、これはバックセットが大きく錠ケース1が長いものの場合であるから、鎌 部材8自体は上記第1の考案の引違い戸用錠のものを共用しており、長いもので ある。そのため、該鎌部材8が後部の連結用ピン12を支点に回動すると、上記 第1の考案の引違い戸用錠と同様に、先端の鉤形状部9が動く上下動幅は大きい から、確実な施錠状態を得ることができる。[0017] Regarding the rotation of the sickle member 8 described above, in the sliding door lock of the second invention, the horizontally long sickle member 8 is used. Although the auxiliary plate 14 is connected to the rear portion of the shape portion 10, it is different from the one using the conventional link. This is the case when the back set is large and the lock case 1 is long. The member 8 itself is the same as the sliding door lock of the first invention, and is a long member. is there. Therefore, when the sickle member 8 pivots about the rear connecting pin 12 as a fulcrum, Like the sliding door lock of the first invention, the vertical movement width of the hook-shaped portion 9 at the tip end is large. Therefore, a reliable locked state can be obtained.
【0018】 上記の掛止状態時に、鎌部材8先端の鉤形状部9を従来のものより長めに形成 してあれば、これも受け金具20への掛止を確実に行うことに役立っており、こ の掛止状態時のハブ5の係止用外周部をセクション用バネ13が押圧して、該ハ ブ5の不用意な回動を阻止し施錠状態を維持している。 引き戸16を閉める際に、鎌部材8先端の鉤形状部9が前方へ突出したままで は、鉤形状部9が戸枠体19の受け金具20の前面に衝突してしまう。しかし上 記第1または第2の考案の引き戸用錠では、鉤形上部9に加わる衝突力がハブ5 を押圧するセクション用バネ13のバネ力よりも大きいなら、ガイド用ピン11 はガイド用長溝部7の湾曲状部17に沿って後方へ移動し、鎌部材8は直ちにそ のまま直線状部に沿って後方へ移動する。そのため、鎌部材8の鉤形状部9は直 ちに錠ケース1内へ没入することになるから、鉤形状部9や受け金具20が損傷 を受けることがない。[0018] In the hooked state, the hook-shaped portion 9 at the tip of the sickle member 8 is formed longer than the conventional one. If this is done, this is also useful for securely engaging the receiving metal fitting 20, The section spring 13 presses the locking outer peripheral portion of the hub 5 when the hub is locked, The lock 5 is kept in a locked state by preventing unintentional rotation of the bush 5. When closing the sliding door 16, leave the hook-shaped part 9 at the tip of the sickle member 8 protruding forward. The hook-shaped portion 9 collides with the front surface of the receiving fitting 20 of the door frame body 19. But above In the sliding door lock of the first or second invention, the collision force applied to the hook-shaped upper portion 9 causes the hub 5 to move. If it is larger than the spring force of the section spring 13 that presses, the guide pin 11 Moves rearward along the curved portion 17 of the guide long groove portion 7, and the sickle member 8 immediately moves. It moves backward along the straight line. Therefore, the hook-shaped portion 9 of the sickle member 8 is straight. The hook-shaped portion 9 and the receiving metal fitting 20 will be damaged because it will be immersed in the lock case 1 later. Never receive.
【0019】 上記ガイド用長溝部7前寄りの湾曲状部17の先端寄り部分の形状を、ガイド 用ピン11が施錠状態から解錠方向へ移動しようとする際に当たる後内面17a で、後方へ膨らみ状に形成してあれば(例えば図4,図11参照)、湾曲状部1 7の先端位置に有ったガイド用ピン11は、よりスムーズに湾曲状部17に沿っ て後方へ移動し易くなる。 なおこの引き戸用錠では、鎌部材8の鉤型状部9が受け金具20内の掛止部材 21に掛止された施錠状態時に、鎌部材8のガイド用ピン11が錠ケース1のガ イド用長溝部7の先端部に有る(図3・図10参照)。そのため、引き戸が無理 やりに開けられようとした場合に、その外力は、鎌部材8のガイド用ピン11が 錠ケース1のガイド用長溝部7の先端部に掛止されることで受け止められ、従来 のものと異なりそれ以外の部品には伝わらない。しかも従来のものと異なり部品 点数が少ないので、スペースやコスト的にも余裕があり、ガイド用ピン11も太 くて十分に強度のあるものを用いられる。これによりこの引き戸用錠は、従来の ものと比べて十分な強度をもつ頑丈なものになっているから、施錠状態時に引き 戸が無理やり開けられようとした場合にも、錠として十分な信頼性を有する。[0019] The shape of the portion near the tip of the curved portion 17 near the front of the guide long groove portion 7 is Inner surface 17a against which the operating pin 11 strikes when trying to move from the locked state to the unlocking direction If it is formed so as to bulge backward (see, for example, FIGS. 4 and 11), the curved portion 1 The guide pin 11 located at the tip position of 7 more smoothly follows the curved portion 17. It becomes easier to move backward. In addition, in this sliding door lock, the hook-shaped portion 9 of the sickle member 8 is a hook member in the receiving metal fitting 20. The guide pin 11 of the sickle member 8 is locked in the lock case 1 when the lock case 21 is locked. It is located at the tip of the long groove portion 7 for the id (see FIGS. 3 and 10). Therefore, sliding doors are impossible If the guide pin 11 of the sickle member 8 is forced to open it, Conventionally, it is received by being hooked on the tip of the long guide groove 7 of the lock case 1. Unlike the above, it does not reach other parts. Moreover, unlike conventional products Since there are few points, there is plenty of space and cost, and the guide pin 11 is thick. The one that is strong enough is used. This makes this sliding door lock It is strong enough to be strong compared to other items, so pull it when it is locked. Even if the door is forcibly opened, it has sufficient reliability as a lock.
【0020】 次に、解錠して引き戸16を開ける場合には、第1の考案の引違い戸用錠も第 2の考案の引違い戸用錠も、つまみ等の操作部材を上記の施錠の場合とは逆方向 へ回動させて、角軸18を介して錠ケース1内のハブ5を逆回り(図示例では左 回り)に回動させればよい。これでハブ5が、それと係合している連結用ピン1 2または第2の連結用ピン15を介して、鎌部材8を後方(図示例では右方向) へ引く。 これで、各鎌部材8の横長状部10中央寄りのガイド用ピン11が、ガイド用 長溝部7前部寄りの湾曲状部17に沿って下方または上方(図示例では下方)へ 移動し、鎌部材8は各連結用ピン12を支点として下方または上方(図示例では 下方)へ回動する。そのため、先端の鉤形状部9も下方または上方(図示例では 下方)へ回動して、受け部材20内の掛止部材21との掛止が外れ、解錠状態と なる。その後続いて鎌部材8がガイド用長溝部7に沿って後退することで、鉤形 状部9は受け金具20から出て錠ケース1内へ没入する(例えば図1,図9参照 )。[0020] Next, when unlocking and opening the sliding door 16, the sliding door lock of the first invention is also first. In the sliding door lock of the second invention, the operation member such as the knob is in the opposite direction to the case of the above locking. To rotate the hub 5 in the lock case 1 in the opposite direction via the square shaft 18 (in the illustrated example, left side It may be rotated around). The hub 5 is now in engagement with the connecting pin 1 The sickle member 8 is rearward (to the right in the illustrated example) via the second or second connecting pin 15. Pull to. With this, the guide pin 11 near the center of the horizontally long portion 10 of each sickle member 8 is used for the guide. Downward or upward (downward in the illustrated example) along the curved portion 17 near the front of the long groove portion 7 The sickle member 8 moves downward or upward (in the illustrated example, with the connecting pins 12 as fulcrums). Rotate downward). Therefore, the hook-shaped portion 9 at the tip also moves downward or upward (in the illustrated example, When it is rotated to the lower side), the engagement with the engagement member 21 in the receiving member 20 is released, and the unlocked state is established. Become. After that, the sickle member 8 retreats along the long groove portion 7 for the guide to form a hook shape. The shaped portion 9 comes out of the receiving metal fitting 20 and sinks into the lock case 1 (see, for example, FIGS. 1 and 9). ).
【0021】 この解錠状態時にも、セクション用バネ13がその状態でのハブ5の係止用外 周部を押圧して、ハブ5が不用意に回動するのを阻止し解錠状態が維持されるか ら、後は引き戸16を引いて開ければよい。 なお上記の如く、ガイド用長溝部7前寄りの湾曲状部17の先端寄り部分の形 状を、ガイド用ピン11が施錠状態から解錠方向へ移動しようとする際に当たる 後内面17aで、後方へ膨らみ状に形成してあれば、施錠状態時に湾曲状部17 の先端位置に有ったガイド用ピン11は、よりスムーズに湾曲状部17に沿って 後方へ移動し易くなっており、解錠が一層円滑に行われる。[0021] Even in this unlocked state, the section spring 13 is used for locking the hub 5 in that state. Whether the hub 5 is pressed to prevent inadvertent rotation of the hub 5 and the unlocked state is maintained After that, the sliding door 16 may be pulled and opened. As described above, the shape of the portion near the tip of the curved portion 17 near the front of the long guide groove 7 is formed. When the guide pin 11 tries to move from the locked state to the unlocked direction, If the rear inner surface 17a is formed so as to bulge rearward, the curved portion 17 will be formed in the locked state. The guide pin 11 located at the tip position of the Since it is easy to move backward, unlocking can be performed more smoothly.

Having said that, it is essential to provide a connecting link between the hub and the sickle member. The hubs also required complex shapes, which pushed up material and manufacturing costs.
【0033】 またその作動状態は、鎌部材が前進時に錠ケースの前部で、鎌部材の斜状のガ イド面が通挿穴の開口縁部に係合して押し上げられるか、または鎌部材の後端上 位置の凸部が錠ケースのストッパーピンに係合し、かつ下端後部の凸部が錠ケー スのストッパーに係合して押し上げられるものであった。そのため、鎌部材の前 進後退移動にガタツキが生じる可能性があり、動きが必ずしもスムーズに行われ るとは限らないし、また前寄り位置へ移動時の回動も常にスムーズに回動すると は限らなかった。[0033] Also, the operating state is that the sickle member is in the front part of the lock case when the sickle member is moving forward, The id surface is pushed up by engaging the opening edge of the insertion hole or on the rear end of the sickle member. The convex part of the position engages with the stopper pin of the lock case, and the convex part at the rear of the lower end is the lock case. It was to be pushed up by engaging the stopper of the roller. Therefore, in front of the sickle member There may be some rattling in the forward / backward movement, and the movement is not always smooth. It is not always the case, and the rotation when moving to the front position is always smooth. Was not always.
【0034】 さらに、鎌部材の後端にリンクを設けることが不可欠であるから、そのリンク の長さ分だけ鎌部材が短くなっている。そのため、鎌部材は先端の鉤形状部から 回動時の支点までの間の距離が短く、回動時における鉤形状部の上下動幅は、回 動角が同じでも短くなっおり、受け金具の取付け位置との間に取付け誤差がある と、鉤形状部が掛止部材にうまく掛止されないこともあった。 しかも,施錠状態時に引き戸を無理やりに開けようとされる場合に、その外力 は鎌部材からピン・リンク・鎌部材の各部に伝わるので、強度上でのトラブルの 心配があり信頼性にやや問題があった。[0034] Furthermore, it is essential to provide a link at the rear end of the sickle member, so that link The sickle member is shortened by the length of. Therefore, the sickle member starts from the hook-shaped part at the tip. The distance to the fulcrum during rotation is short, and the vertical movement width of the hook-shaped portion during rotation is Even if the moving angle is the same, it is shorter, and there is a mounting error with the mounting position of the bracket. Then, the hook-shaped portion may not be properly hooked on the hook member. Moreover, when the sliding door is forcibly opened in the locked state, the external force Is transmitted from the sickle member to each part of the pin, link, and sickle member, so there is no trouble in strength. I was worried and had some problems with reliability.
【0035】 これに対して本考案に係る引き戸用錠では、a)上記第1の考案の引き戸用錠 の鎌部材は、該鎌部材自体の後方への横長状部の後部が、連結用ピンを介してハ ブと連結しており、またハブの構造も、比較的シンプルな形状のものでよい。そ のために、従来のものと異なり、リンクが不要となって構造を一層簡素化できる し、またハブもシンプルな形状でよいから、材料費や製造コストを低減すること ができる。 b)また上記第2の考案の引き戸用錠は、取付け時のバックセットが大きい場 合に用いるもので、鎌部材の後部にバックセット拡大用の補助板を設けるだけで ある。そのため、操作部材、受け金具、ハブ、ガイド用ピン、連結用ピン,セク ション用バネ等は、上記第1の考案の引き戸用錠と共用できるよになっており、 部品の種類を少なくできて、上記第1のものと大差ない程にコストダウンを図る ことができる。[0035] On the other hand, in the sliding door lock according to the present invention, a) the sliding door lock of the first invention described above. As for the sickle member of the sickle member, the rear part of the laterally long part to the rear of the sickle member itself is connected through the connecting pin. The hub structure may be relatively simple. So Because of this, unlike the conventional one, no link is required and the structure can be further simplified. In addition, since the hub can have a simple shape, material cost and manufacturing cost can be reduced. You can b) In addition, the sliding door lock of the second invention is used when the back set at the time of mounting is large. It is used in combination, just by providing an auxiliary plate for expanding the back set at the rear of the sickle member is there. Therefore, operating members, brackets, hubs, guide pins, connecting pins, security The spring for the spring can be shared with the lock for the sliding door of the first invention, The number of parts can be reduced, and the cost can be reduced to the same extent as the first one. be able to.
【0036】 c)さらに上記第1の考案の引き戸用錠では、鎌部材の横長状部中央寄りのガ イド用ピンと後部寄りの連結用ピンが、また上記第2の考案の引き戸用錠ではそ れに加えて補助板後部の第2の連結用ピンが、いずれも各々錠ケース両内側面の ガイド用長溝部に係合しており、それに沿って前後移動する。そのため、鎌部材 は前進および後退移動は常に確実かつスムーズに行うことができる。 d)しかも、上記のハブの回動で、鎌部材のガイド用ピンがガイド用長溝部に 沿って前進し、そのまま長溝部前部寄りに続く湾曲状部へ移行することにより、 先端の鉤形状部が上方または下方へ回動して、受け金具内で掛止される。そのた め、鎌部材の先端の鉤形状部の上方または下方への回動は、何の障害もなくスム ーズかつ正確に行われることになり、作動上のトラブルが生じることはない。[0036] c) Furthermore, in the sliding door lock of the first invention, the lock is located near the center of the horizontally long portion of the sickle member. The id pin and the rearwardly connecting pin are the same as those in the sliding door lock of the second invention. In addition to this, the second connecting pin on the rear part of the auxiliary plate is It engages with the long guide groove and moves back and forth along it. Therefore, sickle member The forward and backward movements are always reliable and smooth. d) Moreover, the rotation of the hub causes the guide pin of the sickle member to move into the long guide groove. By advancing along and moving to the curved portion continuing to the front of the long groove portion as it is, The hook-shaped part at the tip turns upward or downward and is hooked in the receiving metal fitting. That Therefore, turning the hook-shaped part at the tip of the sickle member upward or downward does not cause any hindrance. The operation is accurate and accurate, and no operational trouble occurs.
【0037】 e)そして上記鎌部材の回動で先端の鉤形状部が動く上下動幅は、上記第1・ 第2の考案の引き戸用錠の鎌部材が、リンクを用いず鎌部材自体の横長状部が長 くなっており、その後部の連結用ピンが回動の支点となっている。そのため、仮 に鎌部材の回動角度が従来のものと同一であったとしても、鎌部材の横長状部が 長くなっている分だけ先端の鉤形状部の上下動幅を大きくできる。これにより、 引き戸用錠と受け金具との間で取付け位置に誤差があったとしても、鉤形状部は 余裕を持って受け金具内で掛止部材の位置に達して、確実な施錠状態を得ること ができる。[0037] e) And the vertical movement width in which the hook-shaped portion at the tip moves by the rotation of the sickle member is The sickle member of the sliding door lock of the second invention is such that the horizontally long portion of the sickle member itself is long without using a link. The connecting pin at the rear part serves as a fulcrum for rotation. Therefore, provisional Even if the rotation angle of the sickle member is the same as the conventional one, the horizontally long part of the sickle member is The vertical movement width of the hook-shaped part at the tip can be increased as much as it is longer. This allows Even if there is an error in the mounting position between the sliding door lock and the receiving metal fitting, the hook shape part To reach the position of the latching member within the bracket with a margin and to obtain a secure locked state. You can
【0038】 f)上記の鎌部材の回動に関して、第2の考案の引き戸用錠では鎌部材の横長 状部の後部に補助板を連結してあるが、従来のリンクを用いたものと異なり、こ れはバックセットが大きく錠ケースが長いものの場合であるから、鎌部材自体は 上記第1のものと同じく長いものになっている。そのため、該鎌部材が後部の連 結用ピンを支点に回動すると、上記第1の考案の引違い戸用錠と同様に、先端の 鉤形状部が動く上下動幅は大きくなっており、確実な施錠状態を得ることができ る。[0038] f) With regard to the rotation of the sickle member, in the sliding door lock of the second invention, the sickle member is horizontally long. An auxiliary plate is connected to the rear part of the shaped part, but unlike the one using a conventional link, this This is the case when the back set is large and the lock case is long, so the sickle member itself It is as long as the first one. Therefore, the sickle member is connected to the rear part. When the connecting pin is rotated about the fulcrum, the tip of the sliding door is locked like the sliding door lock of the first invention. The vertical width of movement of the hook-shaped part is large, so a secure locked state can be obtained. It
【0039】 g)また、上記第1・第2の考案の引き戸用錠で、施錠状態時に引き戸が無理 やりに開けられようとした場合に、その外力は鎌部材のガイド用ピンが錠ケース のガイド用長溝部7の先端部に掛止されることで受け止められており、従来のも のと異なりそれ以外の部品には伝わらない。しかも従来のものと異なり部品点数 が少ないので、ガイド用ピンも太くて十分な強度のものを用いられる。これによ りこの引き戸用錠は、従来のものと比べて十分な強度をもち頑丈にできているか ら、施錠状態時に引き戸が無理やり開けられようとした場合に対しても、錠とし て十分な信頼性を有するものにできる。[0039] g) Also, with the sliding door lock of the above first and second inventions, the sliding door cannot be pushed in the locked state. When it is about to be opened, the guide pin of the sickle member locks the external force. It is received by being hooked at the tip of the long groove portion 7 for guide of Unlike the above, it is not transmitted to other parts. Moreover, unlike conventional products, the number of parts However, the guide pin is thick and has sufficient strength. By this Is the Riko sliding door lock strong enough and strong compared to the conventional one? Even if the sliding door is forcibly opened when locked, And have sufficient reliability.
【0040】 h)鎌部材先端の鉤形状部が突出した状態で引き戸を閉めた際、戸枠体側の受 け金具に衝突したとしても、その押圧力で鎌部材はガイド用ピンが前部寄りの湾 曲状部からガイド用長溝部へ確実かつスムーズに移行できる。そのため、鎌部材 はハブを押圧するセクション用バネに打ち勝って後退し、先端の鉤形状部や受け 金具は過大な衝撃力を受けず、損傷を防止することができる。 i)なお、ガイド用長溝部前寄りの湾曲状部の先端寄り部分の形状を、ガイド 用ピンが施錠状態から解錠方向へ移動しようとする際に当たる後内面で、後方へ 膨らみ状に形成したものでは、施錠状態時に湾曲状部の先端位置に有ったガイド 用ピンは、よりスムーズに湾曲状部に沿って後方へ移動し易くなっているから、 解錠作動を一層円滑に行うことができる。[0040] h) When the sliding door is closed with the hook-shaped part at the tip of the sickle member protruding, Even if it hits the metal fittings, the pressing force of the sickle member causes the guide pins to move toward the front of the bay. The curved portion can be reliably and smoothly moved to the long groove portion for guide. Therefore, sickle member Overcomes the section spring that presses the hub and retracts, causing the tip of the hook or the The metal fitting does not receive an excessive impact force and can prevent damage. i) Make sure that the shape of the curved portion near the front of the long guide groove is close to the guide. At the rear inner surface, which the contact pin hits when trying to move from the locked state to the unlocked direction, move backward With a bulging shape, the guide located at the tip of the curved part when locked Since the work pin is more easily moved rearward along the curved portion, The unlocking operation can be performed more smoothly.
