一方、取付け板40の内面40aには、図8で示すように、フックレバー16をロックするロック片55が見える。ロック片55はフックレバー16の支持部20と係脱可能である。なお、取付け板40の下部には、手動式錠手段11の駆動片14を通すための開口41が形成されている。   On the other hand, a lock piece 55 for locking the hook lever 16 is visible on the inner surface 40a of the mounting plate 40 as shown in FIG. The lock piece 55 can be engaged with and disengaged from the support portion 20 of the hook lever 16. An opening 41 for passing the drive piece 14 of the manual lock means 11 is formed in the lower part of the mounting plate 40.

(9)自動式錠手段
自動式錠手段45は、本実施例では取付け板40の内面40a及び外面40bの両面に装着される。しかして、自動式錠手段45は、取付け本体3の外面(表面)40b側に固定された駆動源46と、この駆動源46の駆動力により作動する作動杆47と、この作動杆47の伸縮動に対応して所定量回動する係合作動片48と、この係合作動片48と横軸49を介して一体的に設けられ、かつ、取付け本体3の内面(裏面)40a側に位置すると共にフックレバー16と係脱するロック片55とから成る。
(9) Automatic locking means The automatic locking means 45 is mounted on both the inner surface 40a and the outer surface 40b of the mounting plate 40 in this embodiment. Thus, the automatic locking means 45 includes a drive source 46 fixed to the outer surface (surface) 40 b side of the mounting body 3, an operating rod 47 that operates by the driving force of the drive source 46, and the expansion and contraction of the operating rod 47. An engagement operation piece 48 that rotates by a predetermined amount corresponding to the movement, and the engagement operation piece 48 and the horizontal shaft 49 are provided integrally, and are located on the inner surface (back surface) 40a side of the mounting body 3. And a hook piece 16 and a locking piece 55 that engages and disengages.

前記駆動源46はソレノイドを採用し、該ソレノイド46は取付け板40の略中央部に縦方向に配設されている。ソレノイド46の垂直作動杆47は、ソレノイド46がOFF(施錠状態)の時は、下方方向へ伸長し、これに対してソレノイド46がON(解錠状態)の時は、上方方向へと収縮する。また前記横軸49は取付け板40に回動自在に設けられていると共に、係合作動片48の一端部は、横軸49の突出外端部に固着具50を介して一体的に設けられている。   The drive source 46 employs a solenoid, and the solenoid 46 is disposed in a vertical direction at a substantially central portion of the mounting plate 40. The vertical operating rod 47 of the solenoid 46 extends downward when the solenoid 46 is OFF (locked state), and contracts upward when the solenoid 46 is ON (unlocked state). . The horizontal shaft 49 is rotatably provided on the mounting plate 40, and one end portion of the engagement operating piece 48 is integrally provided on the protruding outer end portion of the horizontal shaft 49 via a fixing tool 50. ing.

係合作動片48は、その突起状中間部が作動杆47の突出端部に適宜枢支されていると共に、その他端部には鉤状の係合部51が形成されている。さらに、係合作動片48の側壁部52は、図9及び図10で示すように、横軸49に巻装されたソレノイド用のバネ部材53の一端部を受けるバネ受け機能と、取付け板40に形成したストッパ54に当接するストッパ当接機能とを有する。   The projecting intermediate portion of the engagement operation piece 48 is pivotally supported by the projecting end portion of the operation rod 47, and a hook-shaped engagement portion 51 is formed at the other end portion. Further, as shown in FIGS. 9 and 10, the side wall portion 52 of the engagement operation piece 48 has a spring receiving function for receiving one end portion of a solenoid spring member 53 wound around the horizontal shaft 49 and the mounting plate 40. And a stopper abutting function for abutting against the stopper 54 formed in the above.

ところで、ソレノイド用バネ部材53に関し、その一端部は係合作動片48の側壁部52の内壁面に圧接するが、その他端部はソレノイド46の下端面に圧接する。このバネ部材53は、本実施例では、ソレノイド46がOFF状態の時に作動杆47が伸長するように下方方向(施錠方向)へと付勢する。また前述したストッパ54は、係合作動片48の側壁部52の外壁面と当接することができるように取付け板40の開口41付近に突設され、係合作動片48が横軸49と共に施錠方向へ所定量回動した際に該係合作動片48を所定位置に止める。   Incidentally, one end of the solenoid spring member 53 is in pressure contact with the inner wall surface of the side wall portion 52 of the engagement operating piece 48, while the other end portion is in pressure contact with the lower end surface of the solenoid 46. In the present embodiment, the spring member 53 biases downward (locking direction) so that the operating rod 47 extends when the solenoid 46 is OFF. Further, the stopper 54 described above is protruded in the vicinity of the opening 41 of the mounting plate 40 so as to be able to contact the outer wall surface of the side wall portion 52 of the engagement operation piece 48, and the engagement operation piece 48 is locked together with the horizontal shaft 49. The engagement operation piece 48 is stopped at a predetermined position when it is rotated by a predetermined amount in the direction.

一方、ロック片55に関して説明すると、ロック片55は横軸49の突出内端部に固着具56を介してロック片55と同様に該横軸49に一体的に取付けられている。したがって、ロック片55、横軸49及び係合作動片48は、駆動源46の作動杆47が伸長又は収縮すると、一緒に回動する。   On the other hand, as for the lock piece 55, the lock piece 55 is integrally attached to the horizontal shaft 49 in the same manner as the lock piece 55 via a fixing tool 56 at the protruding inner end portion of the horizontal shaft 49. Therefore, the lock piece 55, the horizontal shaft 49, and the engagement operation piece 48 rotate together when the operation rod 47 of the drive source 46 extends or contracts.

しかして、本実施例のロック片55は、ソレノイド46がOFF状態の時は、フックレバー16の回転軌跡上(例えばフックレバー16の下端部内面と対面関係)にあり、フックレバー16が傾倒しないようにロックする。   Therefore, when the solenoid 46 is in the OFF state, the lock piece 55 of this embodiment is on the rotation locus of the hook lever 16 (for example, facing the inner surface of the lower end portion of the hook lever 16), and the hook lever 16 does not tilt. To lock.

これに対し、ソレノイド46がON状態の時は、作動杆47が収縮するので、係合作動片48及びロック片55は、解錠方向へと回転し、その結果、ロック片55はフックレバー16の回転軌跡上から外れ、フックレバー16を倒すことが可能となる。
その他の構成について説明すると、前述した横軸49の中央部には、取付け板40の内面40aと摺接する周鍔57が設けられ、さらに、該周鍔57をカバーする軸受板58が取付け板40の内面40aに固定的に添設されている。
On the other hand, when the solenoid 46 is in the ON state, the operating rod 47 contracts, so that the engagement operating piece 48 and the lock piece 55 rotate in the unlocking direction. As a result, the lock piece 55 is moved to the hook lever 16. And the hook lever 16 can be brought down.
The other configuration will be described. In the central portion of the horizontal shaft 49 described above, a peripheral flange 57 that is in sliding contact with the inner surface 40 a of the mounting plate 40 is provided, and a bearing plate 58 that covers the peripheral flange 57 is further provided on the mounting plate 40. Is fixedly attached to the inner surface 40a.

(10)不正解錠防止機構
前述したように取付け板40の外面40bには、自動式錠手段45の係合作動片48に関係付けられた不正解錠防止機構Yが設けられている。この不正解錠防止機構Yは、施錠時に取付け本体3又は/及びフックレバー16の上部を叩き付けた時の衝撃によって係合作動片48に係合する跳ね上がり係止片60を備えている。
(10) Unauthorized Unlocking Prevention Mechanism As described above, the unauthorized unlocking prevention mechanism Y related to the engagement operation piece 48 of the automatic locking means 45 is provided on the outer surface 40b of the mounting plate 40. The unauthorized unlocking prevention mechanism Y includes a bounce-up locking piece 60 that engages with the engagement operation piece 48 by an impact when the upper part of the mounting body 3 and / or the hook lever 16 is hit at the time of locking.

しかして、本実施例の不正解錠防止機構Yは、取付け板40の固定軸61に軸支された跳ね上がり係止片60と、この跳ね上がり係止片60を所定の係合解除の位置に支持することができるように固定軸61に設けられた支持バネ62と、この支持バネ62の支持端部62aが当接する取付け板40の支持片42とから成る。   Therefore, the unauthorized unlocking prevention mechanism Y of the present embodiment supports the jumping-up locking piece 60 pivotally supported by the fixed shaft 61 of the mounting plate 40 and the jumping-up locking piece 60 at a predetermined disengagement position. The support spring 62 is provided on the fixed shaft 61 so that the support end 62a of the mounting plate 40 is in contact with the support spring 62.

支持バネ62の支持端部62aは、前記支持片42に当接した状態で係合解除の位置にある跳ね上がり係止片60の一端部側を支持している。   The support end 62 a of the support spring 62 supports one end of the spring-up locking piece 60 that is in the disengagement position while being in contact with the support piece 42.

換言すれば、跳ね上がり係止片60の一端部の下面は、反発力を有する支持バネ62の傾斜状支持端部62aに乗っかっているので、支持バネ62の支持端部62aは、扉開閉用ハンドル掛け金装置の上部をハンマーなどで叩き付けた場合に、その衝撃と共に支持バネ62の反発力(復帰力)により、跳ね上がり係止片60を係合方向へと助長回転させる踏み台的機能を果たす。   In other words, since the lower surface of the one end portion of the spring-up locking piece 60 is on the inclined support end portion 62a of the support spring 62 having a repulsive force, the support end portion 62a of the support spring 62 is the door opening / closing handle. When the upper part of the latching device is struck with a hammer or the like, the stepping-up function is achieved in which the rebounding force (returning force) of the support spring 62 and the impact spring are urged to rotate the jumping locking piece 60 in the engaging direction.

ところで、跳ね上がり係止片60の固定軸61に軸支された一端部側には、係合作動片48と係脱するフック状係合部60aが形成され、一方、他端部側には、図4で示すように錘63が設けられている。該錘63は跳ね上がり係止片60の他端部(自由端部)に設けられているから、衝撃時、支持バネ62の支持端部62aの弾性変位を促し、跳ね上がり係止片60の跳ね上がりを「はずませる」補助機能を有する。   Incidentally, a hook-like engagement portion 60a that engages with and disengages from the engagement operation piece 48 is formed on one end portion of the spring-up locking piece 60 that is pivotally supported by the fixed shaft 61, and on the other end side, As shown in FIG. 4, a weight 63 is provided. Since the weight 63 is provided at the other end portion (free end portion) of the spring-up locking piece 60, the elastic displacement of the support end portion 62a of the support spring 62 is promoted at the time of impact, and the spring-up locking piece 60 is lifted up. It has an auxiliary function that “disengages”.

(11)不正解錠防止機構の作用
図7、図11及び図12を参照にして不正解錠防止機構の作用について説明する。図7はハンドル掛け金装置の施錠時の状態を示す。この場合には、駆動源46の作動杆47が矢印方向に伸長し、係合作動片48はストッパ54に当接している。また、ロック片55は、図8の実線で示す位置、すなわち、フックレバー16の回転軌跡上にある。
(11) Operation of Unauthorized Unlocking Prevention Mechanism The operation of the unauthorized unlocking prevention mechanism will be described with reference to FIGS. 7, 11, and 12. FIG. 7 shows a state when the handle latching device is locked. In this case, the operating rod 47 of the drive source 46 extends in the direction of the arrow, and the engaging operating piece 48 is in contact with the stopper 54. Further, the lock piece 55 is at the position indicated by the solid line in FIG. 8, that is, on the rotation locus of the hook lever 16.

したがって、自動式錠手段45のロック片55は、フックレバー16の傾倒回転を阻止し得る関係にある。一方、不正解錠防止機構Yの跳ね上がり係止片60は、支持バネ62の支持端部62aに支持された状態で水平状態或いは多少傾斜状態になっており、そのフック状係合部60aは、自動式錠手段45の係合作動片48から離れている。   Therefore, the lock piece 55 of the automatic lock means 45 has a relationship that can prevent the hook lever 16 from tilting and rotating. On the other hand, the flip-up locking piece 60 of the unauthorized unlocking prevention mechanism Y is in a horizontal state or a slightly inclined state while being supported by the support end 62a of the support spring 62, and the hook-like engagement portion 60a is It is away from the engagement operating piece 48 of the automatic locking means 45.

これに対して、図11はハンドル掛け金装置の解錠時の状態を示す。この場合には、駆動源46の作動杆47が矢印方向に収縮し、係合作動片48はストッパ54から離れる。   On the other hand, FIG. 11 shows a state when the handle latch device is unlocked. In this case, the operating rod 47 of the drive source 46 contracts in the direction of the arrow, and the engagement operating piece 48 moves away from the stopper 54.

また、ロック片55は、図8の仮想線で示す位置、すなわち、ロック片55はフックレバー16の回転軌跡上から外れているので、フックレバー16を倒すことが可能となる。このように自動式錠手段45の駆動源46の駆動力により、作動杆47が伸縮すると、係合作動片48及び可動横軸49を介してロック片55はフックレバー16を施・解錠する。   Further, since the lock piece 55 is located at the position indicated by the phantom line in FIG. 8, that is, the lock piece 55 is off the rotation locus of the hook lever 16, the hook lever 16 can be tilted. Thus, when the operating rod 47 expands and contracts by the driving force of the driving source 46 of the automatic locking means 45, the lock piece 55 applies and unlocks the hook lever 16 via the engagement operating piece 48 and the movable horizontal shaft 49. .

上記のような施・解錠態様に於いて、施錠時に、泥棒が取付け本体3又は/及びフックレバー16の上端部を、図示しない道具で叩き付けたと仮定する。この時、当然のことながら、取付け本体3に上下方向に「ドーン」というような振動が発生する。この時、取付け本体3の上下方向の衝撃(振動)により、前述したように駆動源の作動杆47が収縮しようとするが、該作動杆47が収縮する寸前、それよりも先に跳ね上がり係止片60が固定軸61を支点に係合方向へと回転する。その結果、そのフック状係合部60aは、自動式錠手段45の係合作動片48に係合する(図12参照)。   In the above-described locking / unlocking mode, it is assumed that the thief hits the mounting body 3 and / or the upper end of the hook lever 16 with a tool (not shown) during locking. At this time, as a matter of course, vibration such as “dawn” is generated in the mounting body 3 in the vertical direction. At this time, due to the impact (vibration) in the vertical direction of the mounting body 3, the operating rod 47 of the drive source tends to contract as described above, but it jumps up and stops immediately before the operating rod 47 contracts. The piece 60 rotates in the engaging direction with the fixed shaft 61 as a fulcrum. As a result, the hook-like engaging portion 60a engages with the engaging operation piece 48 of the automatic locking means 45 (see FIG. 12).

その理由は、係合作動片48には他の部材(駆動源の作動杆47、バネ部材53、横軸49など)の抵抗が働く反面、跳ね上がり係止片60は踏み台的機能を有する支持バネ62に支持されており、また、「はずませる」補助機能を有する錘63が自由端部に設けられているからである。   The reason for this is that the resistance of other members (such as the driving rod 47 of the drive source, the spring member 53, the horizontal shaft 49, etc.) acts on the engagement operating piece 48, while the jumping locking piece 60 has a stepping spring function. This is because a weight 63 that is supported by 62 and has an auxiliary function of “disengaging” is provided at the free end.

したがって、泥棒が自動式錠手段45を備えているハンドル掛け金装置Xをハンマーなどで叩き付けても、自動式錠手段のフックレバー16と係脱するロック片55が容易に解錠状態にならない。   Therefore, even if the thief hits the handle latch device X provided with the automatic lock means 45 with a hammer or the like, the lock piece 55 that engages and disengages with the hook lever 16 of the automatic lock means does not easily become unlocked.

第1実施利に於いて、支持バネ62は、跳ね上がり係止片60を所定の係合解除の位置に支持する機能を有すれば良いから、必ずしも固定軸61に設ける必要はない。例えば支持バネ62の一例としての板バネの一端部を取付け板40に適宜固定し、その自由端部62aで跳ね上がり係止片60を支持しても良い。   In the first embodiment, the support spring 62 need not necessarily be provided on the fixed shaft 61, as long as it has a function of supporting the spring-up locking piece 60 at a predetermined disengagement position. For example, one end of a leaf spring as an example of the support spring 62 may be appropriately fixed to the mounting plate 40, and the free end 62a may be used to support the jump-up locking piece 60.

次に、この欄では本発明の第2の実施例について説明する。なお、第2実施例は前記第1実施例と発明の目的が同一なので、同一の部分には同一符号を付して重複する説明を省略する。   Next, in this section, a second embodiment of the present invention will be described. Since the object of the second embodiment is the same as that of the first embodiment, the same parts are denoted by the same reference numerals and redundant description is omitted.

図13乃至図16に示す第2実施例は、「取付け板40に、施錠時に取付け本体3又は/及びフックレバー16を叩き付けた時の衝撃によって前記自動式錠手段45の係合作動片48が解錠方向へと移動しないように前記ロック片55の小被係合部(例えば小さな凹所)65と係合する小係合部(例えば小さな突起)66をフックレバー16に設けたこと」を特徴とする。   The second embodiment shown in FIGS. 13 to 16 shows that “the engagement operating piece 48 of the automatic locking means 45 is caused by an impact when the mounting body 3 and / or the hook lever 16 is hit against the mounting plate 40 during locking. The hook lever 16 is provided with a small engagement portion (for example, a small protrusion) 66 that engages with a small engagement portion (for example, a small recess) 65 of the lock piece 55 so as not to move in the unlocking direction. Features.

図14を参照にすると、前記小被係合部65は、フックレバー16の支持部20の内壁面に設けているので、これに対応して前記小係合部66をロック片55の先端部に設けている。ロック片55は、前述したように可動横軸49と共に回転するが、図15で示すように、施錠時には、ロック片55はフックレバー16の支持部20に対面するので、ロック片55の小さな凹所65とフックレバー16の小さな突起とは係合する。   Referring to FIG. 14, the small engaged portion 65 is provided on the inner wall surface of the support portion 20 of the hook lever 16, so that the small engaging portion 66 is correspondingly connected to the distal end portion of the lock piece 55. Provided. As described above, the lock piece 55 rotates together with the movable horizontal shaft 49. However, as shown in FIG. 15, the lock piece 55 faces the support portion 20 of the hook lever 16 when locked, and therefore, the lock piece 55 has a small recess. The point 65 and the small protrusion of the hook lever 16 are engaged.

しかして、泥棒が自動式錠手段45を備えているハンドル掛け金装置Xをハンマーなどで叩き付けても、ロック片55とフックレバー16は、単なる対面関係ではなく、一定の限界を超えない限り、両者の係合が解消しないような係合関係にあるから、衝撃力によってソレノイドの鉄心が上方に跳ね上がり、作動杆が解錠方向(例えば収縮方向)に移動しようとしても、作動杆48が解錠方向へ容易に移動しない。   Even if the thief hits the handle latching device X equipped with the automatic locking means 45 with a hammer or the like, the lock piece 55 and the hook lever 16 are not merely in a face-to-face relationship, so long as they do not exceed a certain limit. Therefore, even if the actuating rod attempts to move in the unlocking direction (for example, the shrinking direction) due to the impact force, the actuating rod 48 is unlocked in the unlocking direction. Does not move easily to.

本実施例に於いて、小被係合部65と小係合部66の係合関係にした理由は、施錠時、取付け本体3の殴打による振動程度ではロック片55は回転せず、一方、手動式錠手段11又は自動式錠手段45からの解錠方向への力が係合作動片48に積極的に作用した場合に於いて、ロック片55の係合力がある限界を超えると、該ロック片55の小さな凹所65がフックレバー16の小さな突起66から外れ、ロック片55は図16で示す仮想線の位置(解錠位置)へと回転する。   In the present embodiment, the reason why the small engaged portion 65 and the small engaging portion 66 are engaged is that the locking piece 55 does not rotate at the degree of vibration caused by the strike of the mounting body 3 during locking, When the force in the unlocking direction from the manual locking means 11 or the automatic locking means 45 is positively applied to the engaging operation piece 48, when the engaging force of the lock piece 55 exceeds a certain limit, The small recess 65 of the lock piece 55 is disengaged from the small protrusion 66 of the hook lever 16, and the lock piece 55 rotates to the position of the phantom line (unlocked position) shown in FIG.

なお、前記小被係合部65と小係合部66の係合関係は逆であっても良いし、また小被係合部65と小係合部66は複数個であっても良い。   Note that the engagement relationship between the small engaged portion 65 and the small engaging portion 66 may be reversed, and the small engaged portion 65 and the small engaging portion 66 may be plural.

本発明は、主にバン型の車輌の後部や側部の開閉扉に取付けられる。   The present invention is mainly attached to the rear and side doors of a van type vehicle.
