Description

本発明は、後端面に回動片の突出した錠本体を、錠箱の内ネジ付取付凹部に螺着するシリンダ錠の取付構造に関し、特に、錠本体を覆うシリンダ筒に、ネジ筒を軸線方向へ所定距離可動自在に設けることでねじ込み式錠箱への回動片付シリンダ錠の取付けを可能とする改良技術に関する。 TECHNICAL FIELD The present invention relates to a cylinder lock mounting structure in which a lock body with a rotating piece projecting on a rear end surface is screwed into a mounting recess with an inner screw of a lock box. TECHNICAL FIELD The present invention relates to an improved technique that enables a cylinder lock with a rotating piece to be attached to a screw-in lock box by providing a predetermined distance in a direction.

扉室外面に表出するシリンダ錠と、扉内に内蔵される錠箱からなる施錠装置は、錠箱が取り付けられた後、シリンダ錠が取り付けられる。このようなシリンダ錠の取付構造には、錠箱に設けられた内ネジ付の取付凹部に、シリンダ錠後端部の外周に形成した外ネジを螺着することで、シリンダ錠を錠箱に取り付けるものがある。一般的に、シリンダ錠の後端面には回動片、所謂、テールピースが突出され、回動片はシリンダ錠に挿入された合鍵の回転に伴って回転される。シリンダ錠は、錠箱に取り付けられた状態で、この回動片が錠箱取付凹部の底面に配置される入力部材、所謂、ダルマに係合する。これにより、合鍵の施解錠操作回転が回動片を介して入力部材に伝わり、錠箱内の施解錠機構を作動させる。 In a locking device including a cylinder lock exposed on the outer surface of the door chamber and a lock box built in the door, the cylinder lock is attached after the lock box is attached. In such a cylinder lock mounting structure, an external screw formed on the outer periphery of the rear end of the cylinder lock is screwed into a mounting recess with an inner screw provided in the lock box, so that the cylinder lock is attached to the lock box. There is something to install. In general, a rotating piece, a so-called tail piece projects from the rear end surface of the cylinder lock, and the rotating piece is rotated in accordance with the rotation of the key inserted in the cylinder lock. When the cylinder lock is attached to the lock box, the rotating piece engages with an input member, so-called dharma, which is disposed on the bottom surface of the lock box attachment recess. Thereby, the locking / unlocking operation rotation of the key is transmitted to the input member via the rotating piece, and the locking / unlocking mechanism in the lock box is operated.

ところで、上記したねじ込み式のシリンダ錠では、回動片が後端面から突出されていない。その代わりに鍵穴に挿入された合鍵の先端が後端面から突出され、錠箱取付凹部の入力部材に係合するようになっている。したがって、ねじ込み式シリンダ錠を、錠箱取付凹部の内ネジに螺合する過程では、後端面に回動片が突出していないため、ねじ込み途中で回動片が入力部材に干渉することがなく、最終ねじ込み位置までシリンダ錠をねじ込んで螺着することが可能となった。 By the way, in the above-described screw-in cylinder lock, the rotating piece does not protrude from the rear end surface. Instead, the leading end of the key inserted into the key hole protrudes from the rear end surface and engages with the input member of the lock box mounting recess. Therefore, in the process of screwing the threaded cylinder lock into the inner screw of the lock box mounting recess, the rotating piece does not protrude from the rear end surface, so that the rotating piece does not interfere with the input member during screwing, The cylinder lock can be screwed and screwed to the final screwing position.

しかしながら、シリンダ錠ねじ込み式の施錠装置において、より防犯性の高いシリンダ錠である、回動片を有するシリンダ錠へ交換したい場合、単にシリンダ錠の後部外周に外ネジを設けるのみでは、シリンダ錠を錠箱取付凹部の内ネジにねじ込む途中で、回動片が入力部材に干渉してしまい、最終ねじ込み位置までシリンダ錠をねじ込めず取付が不可能となった。これに対し、錠箱まで交換すれば、交換作業労力が増大するとともに、部品コストも増大した。このため、内ネジ付の錠箱取付凹部に対し、回動片を有するシリンダ錠を取付可能にするシリンダ錠取付構造の開発要請があった。 However, in a cylinder lock screw-in type locking device, when it is desired to replace the cylinder lock with a rotating piece, which is a more secure crime lock, simply by providing an outer screw on the rear outer periphery of the cylinder lock, In the middle of screwing into the inner screw of the lock box mounting recess, the rotating piece interfered with the input member, and the cylinder lock could not be screwed to the final screwed position, making mounting impossible. On the other hand, if the lock box is replaced, the labor for replacement increases and the part cost also increases. For this reason, there has been a demand for the development of a cylinder lock mounting structure that enables a cylinder lock having a rotating piece to be mounted on a lock box mounting recess with an internal screw.

本発明は上記状況に鑑みてなされたもので、回動片を有するシリンダ錠を内ネジ付の錠箱取付凹部に取り付けできるシリンダ錠の取付構造を提供し、もって、回動片付シリンダ錠の汎用性向上を図ることを目的とする。 The present invention has been made in view of the above situation, and provides a mounting structure of a cylinder lock that can attach a cylinder lock having a rotating piece to a lock box mounting recess with an internal thread. The purpose is to improve versatility.

次に、上記の課題を解決するための手段を、実施の形態に対応する図面を参照して説明する。

It is characterized by being.

このシリンダ錠の取付構造では、シリンダ筒２７の外周面から止め板８７が全高、すなわちシリンダ筒２７の半径方向外側方向の高さ分大きく突出可能となり、回転規制杆３９の当接する掛かり代が容易に大きくかつ安価に確保可能となり、例えばシリンダ筒２７からの削りだし形成などの増大してしまう製造コストをなくす。また、止め板８７に突設した***部がネジ筒３１の後端切欠部８１に嵌合され、止め板８７がネジ筒３１とシリンダ筒２７の相対回転規制部材としても作用する。 In this cylinder lock mounting structure, the stopper plate 87 can protrude from the outer peripheral surface of the cylinder cylinder 27 by a total height, that is, the height of the cylinder cylinder 27 in the radially outward direction, and the contact allowance of the rotation restricting rod 39 is easy. Therefore, it is possible to secure a large and low cost, and for example, an increase in manufacturing costs such as the formation of a chip from the cylinder cylinder 27 is eliminated. Further, the raised portion protruding from the stopper plate 87 is fitted into the rear end notch portion 81 of the screw cylinder 31, and the stopper plate 87 also functions as a relative rotation restricting member between the screw cylinder 31 and the cylinder cylinder 27.

請求項３記載のシリンダ錠の取付構造は、前記シリンダ筒２７の外面に軸線方向で形成された係合溝７１と、
前記ネジ筒３１に形成された前端切欠部８３と、
前記化粧リング２９から突出した係合片６９と、

Screwed into the mounting recess 25. In this screwing process, the engagement piece 69 and the cylinder cylinder 27 can be screwed together while maintaining the relative sliding movement in the axial direction, and interference between the engagement piece 69 and the screw cylinder 31 can be avoided.

本発明に係る請求項１記載のシリンダ錠の取付構造によれば、錠本体に相対回転不能かつ軸線方向に移動不能にシリンダ筒を内設し、外ネジを有するとともに軸線方向に長い長穴を有するネジ筒をシリンダ筒に外挿し、シリンダ筒に突設したピンによりネジ筒をシリンダ筒に対して相対回転不能かつ軸線方向に所定距離可動自在とし、回転規制杆が挿入されることでシリンダ筒の軸線方向の移動を規制する抜け止め部をシリンダ筒に形成したので、化粧リングを介してシリンダ筒及びネジ筒を回転して取付凹部にねじ込み、回動片が入力部材と干渉する位置に達したなら、一旦長穴分シリンダ筒と共に錠本体を引き出して干渉を回避し、ねじ込み完了後、シリンダ筒と共に錠本体を押し込むことで回動片を入力部材へ係合させることができる。この結果、回動片の突出したシリンダ錠を内ネジ付の錠箱取付凹部に取り付けでき、回動片付シリンダ錠の汎用性を向上させることができる。 According to the mounting structure of the cylinder lock according to the first aspect of the present invention, the cylinder cylinder is provided in the lock body so as not to be relatively rotatable and not movable in the axial direction, and has an outer screw and a long hole in the axial direction. The screw cylinder is externally inserted into the cylinder cylinder, and the screw cylinder is made non-rotatable relative to the cylinder cylinder by a pin projecting from the cylinder cylinder and movable in the axial direction by a predetermined distance, and the rotation restriction rod is inserted into the cylinder cylinder. Since the cylinder cylinder is provided with a retaining part that restricts the movement of the cylinder in the axial direction, the cylinder cylinder and the screw cylinder are rotated through the decorative ring and screwed into the mounting recess, reaching the position where the rotating piece interferes with the input member. If this is the case, the lock body can be pulled out together with the cylinder cylinder once to avoid interference, and the screw can be engaged with the input member by pushing the lock body together with the cylinder cylinder after screwing is completed.As a result, the cylinder lock from which the rotating piece protrudes can be attached to the lock box mounting recess with the inner screw, and the versatility of the cylinder lock with the rotating piece can be improved.

請求項２記載のシリンダ錠の取付構造によれば、回転規制杆と、この回転規制杆の当接する抜け止め部の後端側内壁面との間に止め板を挟入したので、シリンダ筒の外周面から止め板を全高分大きく突出させることができ、回転規制杆の当接する掛かり代を容易に大きくすることができる。また、止め板に突設した***部をネジ筒の後端切欠部に嵌合することで、ネジ筒とシリンダ筒の相対回転規制部材としても機能させることができ、ピンと共働させて回転規制強度を高めることができる。 According to the mounting structure of the cylinder lock of the second aspect, since the stopper plate is interposed between the rotation restricting rod and the rear end side inner wall surface of the retaining portion with which the rotation restricting rod comes into contact, The stop plate can be protruded greatly from the outer peripheral surface by the total height, and the contact allowance of the rotation restricting rod can be easily increased. Also, by fitting the raised part protruding from the stopper plate into the notch at the rear end of the screw cylinder, it can also function as a relative rotation restricting member for the screw cylinder and the cylinder cylinder. Strength can be increased.

請求項３記載のシリンダ錠の取付構造によれば、シリンダ筒の外面に軸線方向で係合溝を形成し、ネジ筒に前端切欠部を形成し、化粧リングから係合片を突出させ、この係合片を係合溝に進入させて化粧リングとシリンダ筒の相対回転を規制するとともに、係合片にネジ筒の前端切欠部を嵌入可能としたので、化粧リングを回転すれば、シリンダ筒が化粧リングと同期して回転し、ピンにてシリンダ筒との相対回転が規制されたネジ筒を取付凹部に螺着できる。この螺着過程で、係合片とシリンダ筒を軸線方向に相対スライド可能に係合維持させたままねじ込みを可能にし、かつ係合片とネジ筒の干渉も回避できる。つまり、相対変位を吸収し干渉を回避しつつ係合維持できる。 According to the mounting structure of the cylinder lock of the third aspect, the engaging groove is formed in the axial direction on the outer surface of the cylinder tube, the front end notch is formed in the screw tube, and the engaging piece protrudes from the decorative ring. The engaging piece is inserted into the engaging groove to restrict the relative rotation of the decorative ring and the cylinder tube, and the front end notch portion of the screw tube can be inserted into the engaging piece. Rotates in synchronization with the decorative ring, and a screw cylinder whose relative rotation with the cylinder cylinder is restricted by a pin can be screwed into the mounting recess. In this screwing process, the engagement piece and the cylinder cylinder can be screwed in while maintaining the engagement so as to be relatively slidable in the axial direction, and interference between the engagement piece and the screw cylinder can be avoided. That is, the engagement can be maintained while absorbing the relative displacement and avoiding the interference.

以下、本発明に係るシリンダ錠の取付構造の好適な実施の形態を図面を参照して詳細に説明する。
図１は本発明に係る取付構造を有したシリンダ錠を前面側から見た斜視図、図２は図１のシリンダ錠を後面側から見た斜視図、図３は錠箱内部の側面図である。なお、本実施の形態ではシリンダ錠の鍵穴側を前方、シリンダ錠の回動片側を後方として説明する。
本実施の形態に係るシリンダ錠の取付構造は、後端面１１に回動片であるテールピース１３の突出した錠本体１５を、底面１７にテールピース１３の係合する入力部材であるダルマ１９が配置された錠箱２１の、内ネジ２３付の取付凹部２５に螺着することを目的としている。 DESCRIPTION OF EMBODIMENTS Hereinafter, a preferred embodiment of a cylinder lock mounting structure according to the present invention will be described in detail with reference to the drawings.
1 is a perspective view of a cylinder lock having a mounting structure according to the present invention as seen from the front side, FIG. 2 is a perspective view of the cylinder lock of FIG. 1 as seen from the rear side, and FIG. 3 is a side view inside the lock box. is there. In the present embodiment, the keyhole side of the cylinder lock will be described as the front, and the rotating one side of the cylinder lock will be described as the rear.
The cylinder lock mounting structure according to the present embodiment has a lock main body 15 projecting from a tail piece 13 as a rotating piece on the rear end surface 11 and a dharma 19 as an input member for engaging the tail piece 13 on the bottom surface 17. It is intended to be screwed into the mounting recess 25 with the inner screw 23 of the arranged lock box 21.

そのための主要構成として、本取付構造は、シリンダ筒２７と、化粧リング２９と、ネジ筒３１と、ピン３３と、回転規制杆３９と、抜け止め部４１とを備えている。 As a main configuration for this purpose, the mounting structure includes a cylinder cylinder 27, a decorative ring 29, a screw cylinder 31, a pin 33, a rotation restricting bar 39, and a retaining part 41.

錠箱２１は、内蔵した施解錠機構によって、図３に示すデッドボルト４３を扉の小口から進退させる。進退機構は、錠本体１５のテールピース１３或いはサムターンからダルマ１９に入力される回動操作力によって、デッドボルト４３を進退動作させる。錠本体１５は、扉に彫り込んだ状態に内蔵され、扉小口を覆うフロント板４５を備える。フロント板４５は、デッドボルト４３を進退させるための穴４７を有している。デッドボルト４３は、この穴４７を通過することで、小口から突出し、錠箱内に後退する。 The lock box 21 advances and retracts the dead bolt 43 shown in FIG. 3 from the small edge of the door by a built-in locking / unlocking mechanism. The advance / retreat mechanism moves the dead bolt 43 forward and backward by a turning operation force input to the dharma 19 from the tail piece 13 or thumb turn of the lock body 15. The lock body 15 is built in a state of being carved into the door, and includes a front plate 45 that covers the door edge. The front plate 45 has a hole 47 for moving the dead bolt 43 back and forth. By passing through the hole 47, the dead bolt 43 protrudes from the forehead and retracts into the lock box.

図４は図１に示したシリンダ錠の縦断面図、図５は図１に示したシリンダ錠の水平断面図である。
錠本体１５は、外装部材としての外筒４９を有する。外筒４９には内筒５１が回動自在に内設され、内筒５１はロッキングバー５３によって回転が規制・規制解除される。例えばディスクタイプのタンブラーを有する錠本体１５は、合鍵を抜きとった状態でロッキングバー５３がスプリングによって外筒４９の溝（図示せず）に押しつけられ、この状態で内筒５１を回転させようとしても、ロッキングバー５３の後退する切欠がタンブラーにないため、ロッキングバー５３は溝から抜け出ることができず、内筒５１を回転させることができない。 4 is a longitudinal sectional view of the cylinder lock shown in FIG. 1, and FIG. 5 is a horizontal sectional view of the cylinder lock shown in FIG.
The lock body 15 has an outer cylinder 49 as an exterior member. An inner cylinder 51 is rotatably installed in the outer cylinder 49, and the rotation of the inner cylinder 51 is restricted or released by a locking bar 53. For example, in the lock main body 15 having a disk type tumbler, the locking bar 53 is pressed against a groove (not shown) of the outer cylinder 49 by a spring in a state where the key is removed, and the inner cylinder 51 is rotated in this state. However, since the tumbler does not have a notch to which the locking bar 53 moves backward, the locking bar 53 cannot come out of the groove, and the inner cylinder 51 cannot be rotated.

一方、合鍵が差し込まれると、タンブラーは合鍵のきざみによって押され、切欠がロッキングバー５３に一致して整列する。この状態で内筒５１を回転させると、溝とロッキングバー５３のテーパーによって、スプリングに抗してロッキングバー５３が切欠に入り溝から抜け出て、内筒５１を回転させる。外筒５１の外周には溝を内部に形成するための突起５５が外筒４９の軸線方向に沿って突設されている。 On the other hand, when the key is inserted, the tumbler is pushed by the step of the key, and the notch is aligned with the locking bar 53. When the inner cylinder 51 is rotated in this state, the locking bar 53 enters the notch against the spring and comes out of the groove against the spring due to the groove and the taper of the locking bar 53, and the inner cylinder 51 is rotated. On the outer periphery of the outer cylinder 51, a protrusion 55 is formed along the axial direction of the outer cylinder 49 to form a groove inside.

シリンダ筒２７の先端には飾り筒６１が被せられて固定される。図中６３は、飾り筒下板を示す。化粧リング２９は、シリンダ筒２７の後端から挿入されてこの飾り筒６１の外周側に配置される。化粧リング２９は、後端折り曲げ部２９ａと、飾り筒６１の後端面との間に配設された付勢手段であるバネ６５の付勢力により後方に付勢されるとともに、飾り筒６１の前端からの抜けが規制される。飾り筒下板６３、飾り筒６１は、シリンダ筒２７の凹部６７に加締められ固定される。 A decorative cylinder 61 is put on and fixed to the tip of the cylinder cylinder 27. In the figure, 63 indicates a decorative cylinder lower plate. The decorative ring 29 is inserted from the rear end of the cylinder cylinder 27 and disposed on the outer peripheral side of the decorative cylinder 61. The decorative ring 29 is urged rearward by the urging force of a spring 65 that is urging means disposed between the rear end bent portion 29 a and the rear end surface of the decorative cylinder 61, and the front end of the decorative cylinder 61. Omissions from are regulated. The decorative cylinder lower plate 63 and the decorative cylinder 61 are crimped and fixed in the recess 67 of the cylinder cylinder 27.

図６は図１に示したシリンダ錠の分解斜視図、図７は図６に示したシリンダ筒の分解斜視図、図８はシリンダ筒から錠本体を分離した分解斜視図である。
化粧リング２９には係合片６９が突設され、係合片６９はシリンダ筒２７の外面に軸線方向で形成された係合溝７１に挿入される。係合片６９は、化粧リング２９とシリンダ筒２７を一体回転させる。化粧リング２９が回転されると、シリンダ筒２７と化粧リング２９が同期して回転され、シリンダ筒２７が化粧リング２９と係合維持したままねじ込みに伴って後方へ徐々に相対スライドされる。つまり、化粧リング２９とシリンダ筒２７が、相対回転不能に規制されながら軸線方向に相対スライド自在となっている。これにより、化粧リング２９は、バネ６５により不図示の扉室外面に押付けられて密着取付が可能となっている。 6 is an exploded perspective view of the cylinder lock shown in FIG. 1, FIG. 7 is an exploded perspective view of the cylinder cylinder shown in FIG. 6, and FIG. 8 is an exploded perspective view of the lock body separated from the cylinder cylinder.
An engagement piece 69 projects from the decorative ring 29, and the engagement piece 69 is inserted into an engagement groove 71 formed on the outer surface of the cylinder cylinder 27 in the axial direction. The engagement piece 69 rotates the decorative ring 29 and the cylinder cylinder 27 integrally. When the decorative ring 29 is rotated, the cylinder cylinder 27 and the decorative ring 29 are rotated synchronously, and the cylinder cylinder 27 is gradually slid relative to the rear with screwing while maintaining engagement with the decorative ring 29. That is, the decorative ring 29 and the cylinder cylinder 27 are relatively slidable in the axial direction while being restricted so as not to rotate relative to each other. As a result, the decorative ring 29 is pressed against the outer surface of the door chamber (not shown) by the spring 65 and can be attached closely.

シリンダ筒２７は、錠本体１５を後端から相対回転不能かつ軸線方向に移動不能に内設する。錠本体１５は、突起５５，５５を、シリンダ筒２７の内周面に形成された軸線方向の一対の溝７３，７３に挿入して回転規制される。また、錠本体１５は、シリンダ筒２７の後部内周に嵌入されるＣリング７５によって軸線方向の移動が規制される。 The cylinder tube 27 is provided inside the lock body 15 so as not to be relatively rotatable from the rear end and not movable in the axial direction. The lock body 15 is restricted in rotation by inserting the protrusions 55, 55 into a pair of axial grooves 73, 73 formed on the inner peripheral surface of the cylinder cylinder 27. Further, the movement of the lock body 15 in the axial direction is restricted by a C-ring 75 that is fitted into the inner periphery of the rear portion of the cylinder cylinder 27.

ネジ筒３１は、シリンダ筒２７の後端から外挿される。ネジ筒３１は、内ネジ２３に螺合する外ネジ７７を外周に有するとともに、軸線方向に一対の長い長穴７９，７９及び一対の後端切欠部８１，８１を有する。また、ネジ筒３１の前端には一対の前端切欠部８３，８３が形成され、前端切欠部８３，８３は係合片６９を進入可能としている。 The screw cylinder 31 is externally inserted from the rear end of the cylinder cylinder 27. The screw cylinder 31 has an outer screw 77 screwed to the inner screw 23 on the outer periphery, and has a pair of long elongated holes 79 and 79 and a pair of rear end notches 81 and 81 in the axial direction. In addition, a pair of front end cutout portions 83 and 83 are formed at the front end of the screw cylinder 31, and the front end cutout portions 83 and 83 allow the engagement piece 69 to enter.

シリンダ筒２７には一対の固定穴８５，８５が穿設され、固定穴８５，８５はピン３３，３３を固定する。つまり、ピン３３は、シリンダ筒２７から半径方向外側に突設される。ピン３３は、固定穴８５に圧入固定されても、ネジ固定されてもよい。突出したピン３３は、ネジ筒３１の長穴７９に遊嵌され、ネジ筒３１をシリンダ筒２７に対して相対回転不能かつ軸線方向に所定距離可動させる。 A pair of fixing holes 85, 85 are formed in the cylinder cylinder 27, and the fixing holes 85, 85 fix the pins 33, 33. That is, the pin 33 protrudes radially outward from the cylinder tube 27. The pin 33 may be press-fitted and fixed to the fixing hole 85 or may be screw-fixed. The protruding pin 33 is loosely fitted in the elongated hole 79 of the screw cylinder 31, and the screw cylinder 31 cannot be relatively rotated with respect to the cylinder cylinder 27 and is movable by a predetermined distance in the axial direction.

したがって、化粧リング２９が回転されると、シリンダ筒２７が化粧リング２９と同期して回転され、ピン３３にてシリンダ筒２７との相対回転が規制されたネジ筒３１が取付凹部２５に螺合される。この螺着過程で、係合片６９とシリンダ筒２７を軸線方向に相対スライド可能に係合維持させたままねじ込みが可能となり、かつ係合片６９が前端切欠部８３に進入可能となることで係合片６９とネジ筒３１の干渉も回避される。つまり、相対変位を吸収し干渉を回避しつつ係合維持できる。 Therefore, when the decorative ring 29 is rotated, the cylinder cylinder 27 is rotated in synchronization with the decorative ring 29, and the screw cylinder 31 whose relative rotation with the cylinder cylinder 27 is restricted by the pin 33 is screwed into the mounting recess 25. Is done. In this screwing process, the engaging piece 69 and the cylinder cylinder 27 can be screwed in while maintaining the relative sliding movement in the axial direction, and the engaging piece 69 can enter the front end notch portion 83. Interference between the engagement piece 69 and the screw cylinder 31 is also avoided. That is, the engagement can be maintained while absorbing the relative displacement and avoiding the interference.

図４に示すように、シリンダ筒２７の外周には抜け止め部４１が形成され、抜け止め部４１はネジ筒３１の後端切欠部８１を貫通した回転規制杆３９の先端が挿入される。これにより、シリンダ筒２７は、軸線方向の移動が規制される。つまり、抜け止めされる。本実施の形態において、抜け止め部４１は、平坦部４１ａと、縦溝部４１ｂとからなる。平坦部４１ａと縦溝部４１ｂの間には段部４１ｃが形成され、段部４１ｃと反対側の縦溝部４１ｂは後端側内壁面４１ｄとなる。 As shown in FIG. 4, a retaining portion 41 is formed on the outer periphery of the cylinder tube 27, and the leading end of the rotation restricting rod 39 penetrating the rear end notch portion 81 of the screw tube 31 is inserted into the retaining portion 41. Thereby, the cylinder tube 27 is restricted from moving in the axial direction. That is, it is prevented from coming off. In the present embodiment, the retaining portion 41 includes a flat portion 41a and a vertical groove portion 41b. A step portion 41c is formed between the flat portion 41a and the vertical groove portion 41b, and the vertical groove portion 41b opposite to the step portion 41c serves as a rear end side inner wall surface 41d.

抜け止め部４１の縦溝部４１ｂには止め板８７が挿入される。止め板８７は、回転規制杆３９と後端側内壁面４１ｄの間に挟入される。本実施の形態において、止め板８７は、回転規制杆３９側と後端側内壁面４１ｄ側との２枚の止め板８７ａ，８７ｂに分割されてなる。止め板８７は、中央部が***部となる。止め板８７を挿入することで、シリンダ筒２７の外周面から止め板８７が全高、すなわちシリンダ筒２７の半径方向外側方向の高さ分大きく突出可能となり、回転規制杆３９の当接する掛かり代が容易に大きくかつ安価に確保可能となる。すなわち、シリンダ筒２７からの削りだし形成などでは製造コストが増大してしまうが、そのようなことがない。また、止め板８７に突設した***部がネジ筒３１の後端切欠部８１に嵌合され、止め板８７がネジ筒３１とシリンダ筒２７の相対回転規制部材としても作用する。これにより、ピン３３と共働させて回転規制強度を高めることができる。 A stop plate 87 is inserted into the vertical groove portion 41 b of the retaining portion 41. The stop plate 87 is sandwiched between the rotation restricting rod 39 and the rear end side inner wall surface 41d. In the present embodiment, the stop plate 87 is divided into two stop plates 87a and 87b on the rotation regulating rod 39 side and the rear end side inner wall surface 41d side. The central portion of the stop plate 87 is a raised portion. By inserting the stop plate 87, the stop plate 87 can protrude from the outer peripheral surface of the cylinder tube 27 by a total height, that is, by a height in the radially outward direction of the cylinder tube 27, and the amount of contact with which the rotation restricting rod 39 comes into contact is increased. It can be easily secured at a large size and at a low cost. That is, the manufacturing cost is increased by forming a chip from the cylinder cylinder 27, but this is not the case. Further, the raised portion protruding from the stopper plate 87 is fitted into the rear end notch portion 81 of the screw cylinder 31, and the stopper plate 87 also functions as a relative rotation restricting member between the screw cylinder 31 and the cylinder cylinder 27. Thereby, it can be made to cooperate with the pin 33 and a rotation control intensity | strength can be raised.

次に、上記の構成を有する取付構造の作用を説明する。

図９に示すように、扉９５に形成された錠箱収容空間９７に、錠箱２１を小口開口９９から挿入し、取付板４４をビス１０１，１０１にて小口１０３に固定する。扉９５の室外面９５ａには錠箱２１の取付凹部２５と一致する取付穴１０５を穿設しておく。 Next, the operation of the mounting structure having the above configuration will be described.
FIG. 9 is an explanatory view of the mounting procedure of the lock box mounting step, FIG. 10 is an explanatory view of the mounting procedure of the cylinder lock screwing step, FIG. 11 is a perspective view of the cylinder lock being screwed in from the rear side, and FIG. FIG. 13 is a side view of the cylinder lock in which the rotating piece is engaged with the input member, and FIG. 14 is an explanatory view of the attachment procedure of the rotation restricting step by the rotation restricting rod.
As shown in FIG. 9, the lock box 21 is inserted into the lock box housing space 97 formed in the door 95 from the small opening 99, and the mounting plate 44 is fixed to the small opening 103 with screws 101 and 101. A mounting hole 105 corresponding to the mounting recess 25 of the lock box 21 is formed in the outdoor surface 95a of the door 95.

化粧リング２９を回転することで、シリンダ筒２７及びネジ筒３１を一体回転する。ネジ筒３１の外ネジ７７が取付凹部２５の内ネジ２３に掛ると化粧リング２９を回すことで、ネジ筒３１は錠箱２１にねじ込まれる。錠本体１５のテールピース１３がダルマ１９と干渉する位置に達したなら、図１１，図１２に示すように、一旦長穴７９分シリンダ筒２７と共に錠本体１５をネジ筒３１から引き出し、テールピース１３とダルマ１９の干渉を回避する。 By rotating the decorative ring 29, the cylinder cylinder 27 and the screw cylinder 31 are integrally rotated. When the outer screw 77 of the screw cylinder 31 is engaged with the inner screw 23 of the mounting recess 25, the screw ring 31 is screwed into the lock box 21 by turning the decorative ring 29. When the tail piece 13 of the lock body 15 reaches a position where the tail piece 13 interferes with the dharma 19, as shown in FIGS. 11 and 12, the lock body 15 is once pulled out from the screw cylinder 31 together with the cylinder cylinder 27 for 79 long holes. Interference between 13 and Dharma 19 is avoided.

さらにネジ筒３１がねじ込まれ、テールピース１３がダルマ１９に近接したなら、テールピース１３がダルマ１９と係合可能となる姿勢にシリンダ筒２７を回転調整する。回転調整は、錠本体１５の鍵穴１０７に例えば合鍵（図示せず）を挿入し、合鍵を水平保持することで行う。その後、図１３に示すように、シリンダ筒２７と共に錠本体１５を押し込み、テールピース１３をダルマ１９に係合する。 Further, when the screw cylinder 31 is screwed and the tail piece 13 comes close to the dharma 19, the cylinder cylinder 27 is rotated and adjusted so that the tail piece 13 can be engaged with the dharma 19. The rotation adjustment is performed by inserting, for example, a key (not shown) into the key hole 107 of the lock body 15 and holding the key horizontally. Thereafter, as shown in FIG. 13, the lock body 15 is pushed together with the cylinder cylinder 27, and the tailpiece 13 is engaged with the dharma 19.

次いで、回転規制杆３９のビス頭部３９ａをドライバ１１３で回す。これにより、回転規制杆３９（図３参照）をネジ筒３１の後端切欠部８１に挿入するとともにシリンダ筒２７の平坦部４１ａに当接し、シリンダ筒２７を抜け止めする。つまり、シリンダ筒３３は回転規制杆３９と後端側内壁面４１ｄの間に挟入された止め板８７にて抜け止めされる。なお、テールピース１３の板状部分の延出向きと平坦部４１ａの面との向きを対応させた状態とされていることで、ダルマ１９とテールピース１３との係合と平坦部４１ａへの当接が行われる。そして、最後に、取付板４４に、フロント板４５を取付け、ビス頭部３９ａを覆ってシリンダ錠の取付けを完了する。 Next, the screw head 39 a of the rotation restricting rod 39 is turned by the driver 113. As a result, the rotation restricting rod 39 (see FIG. 3) is inserted into the rear end notch 81 of the screw cylinder 31 and abuts against the flat portion 41a of the cylinder cylinder 27 to prevent the cylinder cylinder 27 from coming off. That is, the cylinder cylinder 33 is prevented from coming off by the stopper plate 87 inserted between the rotation restricting rod 39 and the rear end side inner wall surface 41d. In addition, since the extending direction of the plate-like portion of the tail piece 13 and the direction of the surface of the flat portion 41a are made to correspond to each other, the engagement between the dharma 19 and the tail piece 13 and the contact with the flat portion 41a are performed. Contact is made. Finally, the front plate 45 is attached to the attachment plate 44, and the screw head 39a is covered to complete the attachment of the cylinder lock.

上記したシリンダ錠の取付構造によれば、錠本体１５に相対回転不能かつ軸線方向に移動不能にシリンダ筒２７を内設し、外ネジ７７を有するとともに軸線方向に長い長穴７９を有するネジ筒３１をシリンダ筒２７に外挿し、シリンダ筒２７に突設したピン３３によりネジ筒３１をシリンダ筒２７に対して相対回転不能かつ軸線方向に所定距離可動自在とし、回転規制杆３９が挿入されることでシリンダ筒２７の軸線方向の移動を規制する抜け止め部４１をシリンダ筒２７に形成したので、化粧リング２９を介してシリンダ筒２７及びネジ筒３１を回転して取付凹部２５にねじ込み、テールピース１３がダルマ１９と干渉する位置に達したなら、一旦長穴７９分シリンダ筒２７と共に錠本体１５を引き出して干渉を回避し、ねじ込み完了後、シリンダ筒２７と共に錠本体１５を押し込むことでテールピース１３をダルマ１９へ係合させることができる。この結果、テールピース１３の突出したシリンダ錠を内ネジ２３付の錠箱取付凹部２５に取り付けでき、回動片付シリンダ錠の汎用性を向上させることができる。 According to the mounting structure of the cylinder lock described above, the cylinder cylinder 27 is provided in the lock body 15 so as not to be relatively rotatable and not movable in the axial direction, and has an external screw 77 and a long hole 79 in the axial direction. 31 is extrapolated to the cylinder tube 27, and the pin 33 protruding from the cylinder tube 27 makes the screw tube 31 non-rotatable relative to the cylinder tube 27 and movable in the axial direction by a predetermined distance, and the rotation restricting rod 39 is inserted. As a result, the retaining portion 41 that restricts the movement of the cylinder tube 27 in the axial direction is formed in the cylinder tube 27, so that the cylinder tube 27 and the screw tube 31 are rotated via the decorative ring 29 and screwed into the mounting recess 25. Once the piece 13 reaches a position where it interferes with the dharma 19, the lock body 15 is pulled out together with the cylinder cylinder 27 for 79 minutes to avoid interference, and after screwing is completed, The tailpiece 13 can be engaged to Dharma 19 by pushing the lock body 15 with Linda cylinder 27. As a result, the cylinder lock from which the tail piece 13 protrudes can be attached to the lock box mounting recess 25 with the inner screw 23, and the versatility of the cylinder lock with the rotating piece can be improved.
