Description

本発明は押しボタン式シリンダ錠に関するものである。   The present invention relates to a push button type cylinder lock.

例えば自動車のトランクルーム蓋に使用される押しボタン式シリンダ錠としては、実公平８-２３４９号公報に記載されたものが知られている。この従来例において、シリンダ錠はロータを挿入したシリンダアウタと、シリンダアウタを前後方向に移動自在に収容するケースとを有する。ケースは前端部に孔明き隔壁を備えており、シリンダアウタはケースの後端開口部からケース内に挿入される。このシリンダアウタはケース内に収容されるリターンスプリングにより前方に付勢され、孔明き隔壁にフランジを当接させることによって前方への脱離が防止される。また、ケースの後端開口部にはプレート状のストッパが固定され、リターンスプリング、およびシリンダアウタの後端開口部からの脱離が防止される。   For example, as a push button type cylinder lock used for a trunk compartment cover of an automobile, one described in Japanese Utility Model Publication No. 8-2349 is known. In this conventional example, the cylinder lock includes a cylinder outer in which a rotor is inserted, and a case that accommodates the cylinder outer so as to be movable in the front-rear direction. The case has a perforated partition wall at the front end, and the cylinder outer is inserted into the case from the rear end opening of the case. The cylinder outer is urged forward by a return spring accommodated in the case, and the flange is brought into contact with the perforated partition wall to prevent the cylinder outer from being detached forward. In addition, a plate-like stopper is fixed to the rear end opening of the case, and detachment from the return spring and the rear end opening of the cylinder outer is prevented.

しかし、上述した従来例において、リターンスプリングの反力に抗してプレート状のストッパを装着する作業は面倒で、作業性が劣るという問題がある。また、ストッパを例えば樹脂ブロック等により形成することも可能であるが、この場合にはコスト上昇の原因となる。   However, in the conventional example described above, there is a problem that the work of mounting the plate-shaped stopper against the reaction force of the return spring is troublesome and the workability is inferior. Further, the stopper can be formed of, for example, a resin block, but in this case, it causes an increase in cost.

また、ロータはケースの長さに合わせて個別に製造しなければならないために、部品の共通化も図れないという問題がある。   In addition, since the rotor must be manufactured individually according to the length of the case, there is a problem that the parts cannot be shared.

本発明は、以上の欠点を解消すべくなされたものであって、組み立て作業性が良好で、かつ、構造を簡単にした低廉な押しボタン式シリンダ錠の提供を目的とする。   The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide an inexpensive push-button cylinder lock having good assembly workability and a simplified structure.

本発明によれば上記目的は、
筒状のハウジング２と、
ハウジング２に進退自在に挿入され、ハウジング２内に収容された圧縮スプリング３により前方に付勢される押しボタンケース４と、
押しボタンケース４に挿入されるロータ５を有し、
圧縮スプリング３の付勢力に抗して後方に向かって押し下げ操作可能な押しボタン式シリンダ錠であって、
前記ハウジング２には、圧縮スプリング３、およびロータ５が挿入された押しボタンケース４を挿入可能に前方に開放された主体部２ｂが設けられるとともに、該主体部２ｂの後端には圧縮スプリング３の後端に当接する孔明き底壁１が設けられ、
かつ、前記主体部２ｂには、後方に向かって延びる片持梁状に形成され、挿入される押しボタンケース４の抜け止め部７によって一旦弾性変形して該抜け止め部７の通過を許容した後、弾性復元力により原位置に復帰して抜け止め部７に弾発的に係止し、以後押しボタンケース４の前方への脱離を防止する係止片８が設けられる押しボタン式シリンダ錠を提供することにより達成される。 According to the present invention, the object is

A push-button cylinder lock that can be pushed downward against the urging force of the compression spring 3 ;
The housing 2 is provided with a compression spring 3 and a main portion 2b that is opened forward so that the push button case 4 into which the rotor 5 is inserted can be inserted . The compression spring 3 is provided at the rear end of the main portion 2b. A perforated bottom wall 1 is provided in contact with the rear end of
The main body 2b is formed in a cantilever shape extending rearward, and once elastically deformed by the retaining portion 7 of the push button case 4 to be inserted, the passage of the retaining portion 7 is allowed. Thereafter, the push button cylinder is provided with a locking piece 8 which is returned to its original position by elastic restoring force and is elastically locked to the retaining portion 7 and prevents the push button case 4 from being detached forward. This is accomplished by providing a lock.

押しボタン式シリンダ錠の組立は、ハウジング２の前方開口部から圧縮スプリング３、およびロータ５が挿入された押しボタンケース４を順次挿入して行われる。押しボタンケース４を挿入した状態で、ハウジング２に形成された係止片８は一旦弾性変形して押しボタンケース４の通過を許容した後、弾性復元力により原位置に復帰し、以後押しボタンケース４の離脱方向への移動を規制する。   The assembly of the push button cylinder lock is performed by sequentially inserting the compression spring 3 and the push button case 4 in which the rotor 5 is inserted from the front opening of the housing 2. With the push button case 4 inserted, the locking piece 8 formed on the housing 2 is elastically deformed to allow passage of the push button case 4 and then returns to the original position by elastic restoring force. The movement of the case 4 in the separation direction is restricted.

したがって、この発明において、ハウジング２の前方開口部から部品を順次挿入するだけで組立が完了するために、組立工数の低減を図ることができる上に、構造も簡単になり、コスト低減を図ることができる。   Therefore, in the present invention, since the assembly is completed simply by sequentially inserting the components from the front opening of the housing 2, the number of assembling steps can be reduced, and the structure is simplified and the cost is reduced. Can do.

また、押しボタン式シリンダ錠は、

前記連結杆９には、外周方向に付勢され、押しボタンケース４を貫通してハウジング２内壁に圧接する連結プレート１０が装着され、
かつ、連結プレート１０の先端には、ハウジング２内壁に形成されたクリック溝１１に係止して連結杆９が所定回転位置に達した際に節度感を付与する節度突起１０ａが設けられるように構成することもできる。 Push button cylinder locks
A connecting rod 9 connected to the rotor 5;
The connection plate 9 is attached with a connection plate 10 that is urged in the outer circumferential direction and presses against the inner wall of the housing 2 through the push button case 4.
In addition, a moderation protrusion 10a is provided at the distal end of the connection plate 10 so as to provide a moderation feeling when the connection rod 9 reaches a predetermined rotational position by being engaged with a click groove 11 formed on the inner wall of the housing 2. It can also be configured.

ロータ５に連結される連結杆９には連結プレート１０が装着され、連結杆９は該連結プレート１０を押しボタンケース４の肉質部を貫通させることにより、押しボタンケース４に連結される。   A connecting plate 9 is attached to the connecting rod 9 connected to the rotor 5, and the connecting rod 9 is connected to the push button case 4 by passing the connecting plate 10 through the fleshy portion of the push button case 4.

したがって本発明において、連結杆９と押しボタンケース４を予めサブアッセンブルしておき、ハウジング２に挿入することができるために、組み立て作業性をより向上させることができる。また、連結用の連結プレート１０は節度感付与部品としても機能するために、改めて節度感発生部品を使用する必要がなく、構造が簡単になる。   Therefore, in the present invention, the connecting rod 9 and the push button case 4 can be subassembled in advance and inserted into the housing 2, so that the assembly workability can be further improved. Further, since the connecting plate 10 for connection also functions as a moderation giving component, it is not necessary to use a moderation generating part again, and the structure becomes simple.

以上の説明から明らかなように、本発明によれば、構造が簡単で、かつ、組み立て作業性が良好な押しボタン式シリンダ錠を得ることができる。   As is clear from the above description, according to the present invention, it is possible to obtain a push button type cylinder lock having a simple structure and good assembling workability.

図１ないし５に自動車用シートのロック装置用に構成された本発明の実施の形態を示す。ロック装置は、図５に示すように、車両前方に倒伏操作可能なリアシートのシートバック１２の背面上部に配置されるストライカ１２ａに係脱するラッチ１３と、該ラッチ１３を操作するための押しボタン式シリンダ錠Ａとを有し、シートバック１２を倒伏させると、トランクルーム１４へのアクセス開口が開放されて車内からトランクルーム１４へのアクセスが可能になる。シートバック１２の倒伏操作はストライカ１２ａとラッチ１３との係合が解除されることにより可能になり、係合解除は押しボタン式シリンダ錠Ａの押しボタン１５を押し下げてレバー６によりラッチ１３を動作させて行われる。なお、図５において１６はトランクルーム１４側からラッチ１３を操作するための操作索を示す。   1 to 5 show an embodiment of the present invention configured for an automobile seat locking device. As shown in FIG. 5, the locking device includes a latch 13 that is engaged with and disengaged from a striker 12 a that is disposed on an upper rear surface of a seat back 12 of a rear seat that can be tilted forward of the vehicle, and a push button for operating the latch 13. When the seat back 12 is laid down with the type cylinder lock A, the access opening to the trunk room 14 is opened and the trunk room 14 can be accessed from inside the vehicle. The seatback 12 can be tilted by releasing the engagement between the striker 12a and the latch 13, and the engagement can be released by depressing the push button 15 of the push button type cylinder lock A and operating the latch 13 by the lever 6. To be done. In FIG. 5, reference numeral 16 denotes an operation cord for operating the latch 13 from the trunk room 14 side.

上記押しボタン式シリンダ錠Ａは、図１ないし４に示すように、取り付けフランジ２ａを備えたハウジング２と、ハウジング２内に収容されるボタン組立体１７とを有する。ハウジング２の主体部２ｂは筒状に形成され、後端が孔明き底壁１により閉塞される。孔明き底壁１の中心には、後述する連結杆９のロック突部９ａが挿通可能な杆挿通孔１ａが設けられる。   As shown in FIGS. 1 to 4, the push button cylinder lock A includes a housing 2 having a mounting flange 2 a and a button assembly 17 accommodated in the housing 2. The main body 2 b of the housing 2 is formed in a cylindrical shape, and the rear end is closed by the perforated bottom wall 1. In the center of the perforated bottom wall 1, a gutter insertion hole 1 a into which a lock projection 9 a of a connecting gutter 9 described later can be inserted is provided.

ボタン組立体１７は、押しボタンケース４と、押しボタンケース４の前端部に挿入されるロータ５と、ロータ５の後方に配置される連結杆９とからなり、ハウジング２の前方開口から挿入される。図３（ａ）に示すように、押しボタンケース４は後端部に２条の回り止め突条４ａ、４ａを有し、該回り止め突条４ａをハウジング２のガイド部２ｃに嵌合させることにより、ハウジング２に対する相対回転が規制される。図２（ｂ）に示すように、ガイド部２ｃはハウジング２の長手方向に所定長さで形成されて押しボタンケース４の長手方向への移動を許容し、ガイド部２ｃの終端壁が押しボタンケース４の押し込み方向ストロークを決定する。   The button assembly 17 includes a push button case 4, a rotor 5 inserted into the front end portion of the push button case 4, and a connecting rod 9 disposed behind the rotor 5. The button assembly 17 is inserted from the front opening of the housing 2. The As shown in FIG. 3 (a), the push button case 4 has two detent projections 4 a and 4 a at the rear end, and the detent projection 4 a is fitted into the guide 2 c of the housing 2. As a result, relative rotation with respect to the housing 2 is restricted. As shown in FIG. 2B, the guide portion 2c is formed with a predetermined length in the longitudinal direction of the housing 2 to allow the push button case 4 to move in the longitudinal direction, and the end wall of the guide portion 2c is the push button. The stroke in the pushing direction of case 4 is determined.

上記回り止め突条４ａの後端には該回り止め突条４ａ、４ａ間を連結するようにして抜け止め部７が形成されるとともに、ハウジング２には係止片８が設けられる。係止片８は、弾性変形を容易にするように、後方に延びる片持梁状に形成され、図１に示すように、後端に乗り上げ傾斜面８ａを備える。ボタン組立体１７をハウジング２の前方開口から挿入すると、やがて抜け止め部７は係止片８の乗り上げ傾斜面８ａに干渉し、さらに、ボタン組立体１７を押し込むと、係止片８は一旦弾性変形して抜け止め部７の通過を許容し、抜け止め部７が通過した後は弾性復元力により再び原位置に復帰する。これ以降、抜け止め部７は係止片８の垂直端面８ｂにより前方への移動が規制されるために、ボタン組立体１７は前方開口から離脱することができない。   A retaining portion 7 is formed at the rear end of the detent projection 4 a so as to connect the detent projections 4 a, 4 a, and a locking piece 8 is provided in the housing 2. The locking piece 8 is formed in a cantilever shape extending rearward so as to facilitate elastic deformation, and as shown in FIG. When the button assembly 17 is inserted from the front opening of the housing 2, the retaining portion 7 eventually interferes with the climbing inclined surface 8a of the locking piece 8, and when the button assembly 17 is pushed in, the locking piece 8 is once elasticated. It is deformed to allow passage of the retaining portion 7, and after the retaining portion 7 has passed, it returns to its original position again by elastic restoring force. Thereafter, since the retaining portion 7 is restricted from moving forward by the vertical end surface 8b of the locking piece 8, the button assembly 17 cannot be detached from the front opening.

連結杆９は連結頭部９ｂと、該連結頭部９ｂより細径の軸部９ｃとを有し、軸部９ｃには側方にロック突部９ａが突設される。後述するように、この連結杆９は押しボタンケース４に対して相対回転可能であり、該連結杆９を回転させて、図３（ｂ）に示すように、ロック突部９ａを孔明き底壁１の杆挿通孔１ａに挿通可能とするとボタン組立体１７の押し込み操作が可能になる（解錠状態）。これに対し、図３（ｂ）において鎖線で示すように、連結杆９が上記以外の回転位置にある際（施錠状態）には、ロック突部９ａが杆挿通孔１ａの周壁から内方に向けて立ち上げられるストッパ１ｂに干渉して押し込み操作が禁止される。また、ハウジング２内には、両端が連結杆９の連結頭部９ｂ終端とハウジング２の孔明き底壁１に当接する圧縮スプリング３が収容され、ボタン組立体１７を前方に付勢する。   The connecting rod 9 has a connecting head portion 9b and a shaft portion 9c having a diameter smaller than that of the connecting head portion 9b, and a locking projection portion 9a protrudes laterally from the shaft portion 9c. As will be described later, the connecting rod 9 is rotatable relative to the push button case 4, and the connecting rod 9 is rotated so that the lock projection 9a is perforated as shown in FIG. When it is possible to insert the button assembly 17 into the wall insertion hole 1a of the wall 1, the button assembly 17 can be pushed (unlocked). On the other hand, as shown by a chain line in FIG. 3B, when the connecting rod 9 is in a rotational position other than the above (locked state), the locking projection 9a is inward from the peripheral wall of the flange insertion hole 1a. The push-in operation is prohibited by interfering with the stopper 1b raised upward. The housing 2 accommodates a compression spring 3 whose both ends are in contact with the end of the connection head 9b of the connection rod 9 and the perforated bottom wall 1 of the housing 2, and urges the button assembly 17 forward.

さらに、連結杆９には連結プレート１０が装着される。連結プレート１０は、図３（ａ）に示すように、連結杆９に形成されたプレート挿入溝９ｄに収容される板状体で、圧縮スプリング９ｅにより飛び出し方向に付勢される。一方、押しボタンケース４にはプレート貫通溝４ｂが形成され、上記連結プレート１０をプレート貫通溝４ｂに貫通させることにより、押しボタンケース４内に連結プレート１０を抜去不能に装着できる。プレート貫通溝４ｂは、押しボタンケース４に対して連結杆９が少なくとも所定角度（図示の例では９０°）相対回転できるように、周方向に延長される。   Further, a connecting plate 10 is attached to the connecting rod 9. As shown in FIG. 3A, the connecting plate 10 is a plate-like body accommodated in a plate insertion groove 9d formed in the connecting rod 9, and is urged in the protruding direction by a compression spring 9e. On the other hand, a plate through groove 4 b is formed in the push button case 4, and the connecting plate 10 can be mounted in the push button case 4 so as not to be removed by passing the connecting plate 10 through the plate through groove 4 b. The plate through groove 4b is extended in the circumferential direction so that the connecting rod 9 can rotate relative to the push button case 4 by at least a predetermined angle (90 ° in the illustrated example).

また、連結プレート１０の飛び出し側先端にはＶ字状の節度突起１０ａが形成されるとともに、ハウジング２側には該節度突起１０ａが嵌合可能なクリック溝１１が形成される。クリック溝１１は上記連結杆９の押しボタンケース４内での回転ストロークの始端、および終端に対応して設けられ、図４に示すように、回転ストローク終端に対応する側のクリック溝１１はボタン組立体１７の押し込むストローク長に相当する長さをもってハウジング２の長手方向に延長される。   Further, a V-shaped moderation protrusion 10a is formed at the protruding end of the connecting plate 10, and a click groove 11 into which the moderation protrusion 10a can be fitted is formed on the housing 2 side. The click groove 11 is provided corresponding to the start and end of the rotation stroke in the push button case 4 of the connecting rod 9, and the click groove 11 on the side corresponding to the end of the rotation stroke is a button as shown in FIG. The assembly 17 is extended in the longitudinal direction of the housing 2 with a length corresponding to the length of the stroke to which the assembly 17 is pushed.

ロータ５には複数のタンブラ５ａが装着され、所定の解錠コードを形成されたキープレートにより押しボタンケース４に対して相対回転させることができる。図１に示すように、このロータ５の終端部には飛び出し方向に付勢されるストッパタンブラ１８が装着されるとともに、押しボタンケース４内壁にはタンブラ係止突起４ｃが設けられる。ロータ５を押しボタンケース４の前方開口から挿入すると、ストッパタンブラ１８はタンブラ係止突起４ｃに衝接した後、付勢力に抗して一旦ロータ５内に没入し、再び突出してタンブラ係止突起４ｃに係止し、以降、ロータ５の押しボタンケース４からの脱離が規制される。   A plurality of tumblers 5a are attached to the rotor 5 and can be rotated relative to the push button case 4 by a key plate on which a predetermined unlocking code is formed. As shown in FIG. 1, a stopper tumbler 18 that is urged in the protruding direction is attached to the end portion of the rotor 5, and a tumbler locking projection 4 c is provided on the inner wall of the push button case 4. When the rotor 5 is inserted from the front opening of the push button case 4, the stopper tumbler 18 comes into contact with the tumbler locking projection 4 c, and then once enters the rotor 5 against the urging force, and then protrudes again to protrude the tumbler locking projection. After that, the detachment of the rotor 5 from the push button case 4 is restricted.

このロータ５の終端面には上記連結杆９の前端面に嵌合可能な嵌合突起５ｂが設けられ、ロータ５を押しボタンケース４に挿入すると、ロータ５と連結杆９とは回転方向に連結される。   A fitting projection 5b that can be fitted to the front end surface of the connecting rod 9 is provided on the end surface of the rotor 5, and when the rotor 5 is inserted into the push button case 4, the rotor 5 and the connecting rod 9 are rotated in the rotational direction. Connected.

次に、押しボタン式シリンダ錠Ａの組み立て方法を説明する。組み立て作業に当たり、まず、押しボタンケース４と連結杆９とをサブアッセンブルする。サブアッセンブル作業は、押しボタンケース４の後方開口から連結杆９の連結頭部９ｂを挿入するだけで行うことができ、連結頭部９ｂのストッパフランジ９ｆが押しボタンケース４の終端面に当接するまで連結杆９を押し込むと、連結プレート１０がプレート貫通溝４ｂ内に進入して双方の脱離が規制される。次に、押しボタンケース４の前方開口からロータ５を押し入れると、ストッパタンブラ１８の作用でロータ５が脱離不能に押しボタンケース４に収容され、ボタン組立体１７が完成する。   Next, a method for assembling the push button type cylinder lock A will be described. In assembly work, first, the push button case 4 and the connecting rod 9 are sub-assembled. The sub-assembly operation can be performed simply by inserting the connecting head 9b of the connecting rod 9 from the rear opening of the push button case 4, and the stopper flange 9f of the connecting head 9b abuts on the end surface of the push button case 4. When the connecting rod 9 is pushed in, the connecting plate 10 enters the plate through groove 4b and the detachment of both is regulated. Next, when the rotor 5 is pushed in from the front opening of the push button case 4, the rotor 5 is accommodated in the push button case 4 so as not to be detached by the action of the stopper tumbler 18, and the button assembly 17 is completed.

この後、ハウジング２に圧縮スプリング３を挿入した後、上記ボタン組立体１７をハウジング２の前方開口から押し込むだけで、係止片８と抜け止め部７とが係止し、以後、ボタン組立体１７はハウジング２から脱離することはない。この状態で、連結杆９の終端部はハウジング２の終端面からやや突出した状態にあり、該終端部にＥ型止め輪１９等を使用してレバー６が固定され、組み立て作業が完了する。   Thereafter, after the compression spring 3 is inserted into the housing 2, the locking piece 8 and the retaining portion 7 are locked by simply pushing the button assembly 17 through the front opening of the housing 2. 17 does not detach from the housing 2. In this state, the end portion of the connecting rod 9 is slightly protruded from the end surface of the housing 2, and the lever 6 is fixed to the end portion using the E-type retaining ring 19 or the like, and the assembling work is completed.

ボタン組立体１７の終端部に固定されたレバー６は、ボタン組立体１７の抜け止め部材としても機能し、以後、ボタン組立体１７に脱離方向の大きな力を加えても、ハウジング２から引き抜くことができなくなる。   The lever 6 fixed to the terminal portion of the button assembly 17 also functions as a retaining member for the button assembly 17 and is pulled out from the housing 2 even when a large force is applied to the button assembly 17 in the detaching direction thereafter. I can't do that.

なお、上述した実施の形態においては、レバー６を抜け止め部材として兼用する場合を示したが、係止片８と抜け止め部７のみで抜け止めを行うこともできる。   In the above-described embodiment, the lever 6 is also used as a retaining member. However, the retaining member 8 and the retaining member 7 can be used to prevent the retaining member from being detached.

組み立て完了後において、ロータ５を解錠位置まで回転させると、連結プレート１０の節度突起１０ａがクリック溝１１に係止し、使用者に節度感を与える。この状態で、ボタン組立体１７のロック突部９ａは杆挿通孔１ａに合致しており、押しボタン組立体１７を押し込むことができる。再び、ロータ５を回転させると、節度突起１０ａがクリック溝１１に係止して使用者にロータ５が施錠位置まで回転されたことを節度感により知らせる。ロータ５へのキープレートの抜き差しは、ロータ５が施錠位置にあるときにのみ可能であり、利用者はキー抜き差し位置を同時に知ることができる。   After the assembly is completed, when the rotor 5 is rotated to the unlocked position, the moderation protrusion 10a of the connecting plate 10 is locked to the click groove 11 to give a sense of moderation to the user. In this state, the lock projection 9a of the button assembly 17 is aligned with the collar insertion hole 1a, and the push button assembly 17 can be pushed in. When the rotor 5 is rotated again, the moderation protrusion 10a is locked in the click groove 11 to notify the user that the rotor 5 has been rotated to the locked position. The key plate can be inserted into and removed from the rotor 5 only when the rotor 5 is in the locked position, and the user can know the key insertion and removal position at the same time.
