  In the conventional mounting mechanism having the above-described configuration, if a cylinder lock is taken as an example, the length cannot be shortened because the key difference needs to be increased, and the inner end must be arranged near the side plate of the lock box. Therefore, it protrudes greatly from the outer surface of the door.

  For this reason, for example, wearing a frustoconical decorative ring does not look good, obstructs people and things that pass near the door surface, and the portion protruding from the outer surface of the door becomes large. There is still room for improvement.

  Further, since the diameter of the cylinder cylinder or thumb turn is large, the notch hole on the door surface also becomes large, and the cylinder and thumb turn must be attached separately, so that workability is poor.

  Furthermore, since the thumb turn and the cylinder lock are integrally connected via the clutch, it is not possible to respond to the necessity of taking a signal by the movement of the cylinder lock or the thumb turn, such as a security signal lock or an electric lock. There are various disadvantages.

  Accordingly, an object of the present invention is to provide a mounting mechanism that has a good appearance and can improve safety by reducing the amount of projection from the outer surface of the door.

  In order to achieve the above object, the invention described in claim 1 includes a lock unit in which a predetermined gap is maintained between the inner end of the cylinder lock and the thumb turn block, and these are coaxially and integrally connected. In the center of the portion connecting the pair of parallel plate portions, a dharma-shaped clutch hole that engages the tail piece of the cylinder lock inner end, and a cross-shaped thumb turn hole that engages the thumb turn shaft. And an operating arm formed with a coupler formed continuously at a predetermined interval, and the coupler is inserted into a gap between the inner end of the cylinder lock and the thumb turn block, and a pair of parallel plates are connected to the cylinder lock. The operating arm is mounted on the inner cylinder inner end of the cylinder lock so as to be rotatable around the central axis in a manner along the bus of the outer cylinder, while the tip of the operating arm is engaged in the lock box. Locking mechanism with notch The control cylinder is disposed so as to be rotatable around a central axis perpendicular to the side plate of the lock box. On the other hand, with the cylinder lock first, the inner surface of the door, the inner cylinder portion of the dead bolt control cylinder, the lock box, and the outer surface of the door The door is made to pass through the lock unit, the lock unit is restrained in the axial direction, and a decorative ring is attached to the outer end of the cylinder lock protruding slightly on the outer surface of the door.

  Further, the invention according to claim 2 is a lock unit in which a predetermined gap is maintained between the inner end of the cylinder lock and the thumb turn block, and these are coaxially and integrally connected. A cylinder arm in which a dharma-shaped clutch hole that engages the tail piece of the cylinder lock inner end is formed at the center of a portion connecting a pair of parallel plate portions, and the overall shape is a U-shape, A thumb turn arm having a pair of parallel plate portions that maintain a space that can be overlapped on the outside of the plate portion, and a cross-shaped thumb turn hole that engages with the thumb turn shaft is formed at the center of a portion connecting the pair of parallel plate portions; The clutch hole and the thumb turn hole are inserted into the gap between the inner end of the cylinder lock and the thumb turn block while maintaining a predetermined gap, and the pair of parallel plate portions can be relatively rotated, and Siri The cylinder arm and thumb-turn arm are mounted on the inner cylinder end of the cylinder lock so that it can rotate around its central axis while being placed along the bus of the outer cylinder of the lock. The idle control cylinder formed with a notch that engages with the tip of the cylinder arm has a lock mechanism control cylinder with a notch that engages with the tip of the thumb turn arm outside the idle control cylinder. It is arranged so as to be rotatable around a central axis perpendicular to the side plate of the box, and on the other hand, with the cylinder lock first, it penetrates the door inner surface, the inner cylinder part of the dead bolt control cylinder, the lock box and the door outer surface. The lock unit is made to penetrate the door, the lock unit is restrained in the axial direction, and a decorative ring is attached to the outer end portion of the cylinder lock slightly protruding from the outer surface of the door.

  The invention according to claims 1 and 2 configured as described above is configured such that the tail piece and the thumb turn shaft of the cylinder lock are folded and disposed on the outer cylinder of the cylinder lock, and other than the outer end of the cylinder lock. Since the portion is housed in the door, the protruding amount of the cylinder lock on the door outer surface can be made extremely small.

  Therefore, not only the appearance is improved, but the portion exposed to the outer surface of the door is small, so that the resistance to breaking is increased and the safety as a lock is improved.

  In addition, since a large cylinder cylinder or the like required in the conventional mounting mechanism is not required, the diameter of the mounting hole on the door surface can be reduced.

  Furthermore, since the cylinder lock and the thumb turn block can be handled in an integrally coupled state, for example, workability when mounted on a door is improved.

  In addition, since the cylinder lock inner cylinder and the thumb turn can freely rotate relative to each other in the mounting mechanism according to the second aspect of the invention, for example, the rotation angle of the lock key for locking and unlocking the cylinder lock is an angle necessary for locking and unlocking. By making it a little larger, there are various effects such as the increase in the rotation angle can be used to obtain a signal.

  A cylinder arm connected to the inner cylinder of the cylinder lock and a thumb turn arm connected to the thumb turn are molded into a U shape and attached to the inner end of the outer cylinder of the cylinder lock. Was stored in the space inside the door, so that the protruding amount of the cylinder lock from the door outer surface could be minimized.

  A cylinder arm 12 shown in FIG. 3 and a thumb turn arm 14 shown in FIG. 4 are inserted between the cylinder lock 2 and the thumb turn block 3 in a state where they are overlapped vertically.

  The cylinder arm 12 is U-shaped as a whole and has a Dalma-shaped clutch hole 11 that engages with a tail piece 9 (see FIG.) At the inner end of the cylinder lock at the center of a portion connecting a pair of parallel plate portions. On the other hand, the cylinder arm 12 has a pair of parallel plate portions that are U-shaped as a whole, and have a pair of parallel plate portions that can be overlapped outside the parallel plate portions of the cylinder arm 12. It is a frame in which a cross-shaped thumb turn hole 13 that engages with the thumb turn shaft is formed at the center of the portion connecting the plate portions.

  Since the portion where the clutch hole 11 and the thumb turn hole 13 are formed has a shallow cup shape, the cylinder arm 12 and the thumb turn arm 14 are connected to the clutch hole 11 and the thumb turn hole 13 in the same manner as the normal dharma. A predetermined gap is maintained between them, and the tail piece 9 and the thumb turn shaft 15 (see FIG. 2) that engage with each other do not interfere with each other (not shown).

  As shown in FIGS. 1 and 2, the cylinder arm 12 and the thumb turn arm 14 having the above-described configuration are arranged such that the thumb turn arm 14 (FIG. 4) overlaps the cylinder arm 12 (FIG. 3), and the center portion thereof is arranged. Insert the cylinder lock between the inner end of the cylinder lock and the thumb turn block, and allow the parallel plate parts to rotate relative to each other and along the bus bar of the cylinder lock outer cylinder. It is attached to the inner end of the cylinder so as to be rotatable around its central axis.

  The cylinder arm 12 having the above-described configuration is connected to the idle control cylinder 17 so that the front end of the parallel plate portion is engaged with the notch 16 (see FIG. 5).

  Similarly, the thumb turn arm 14 is connected to the locking mechanism control cylinder 18 (see FIG. 6) so that the ends of the pair of parallel plate portions are engaged with the notches 16 and 16, respectively.

  Further, the idle and locking mechanism control cylinders 17 and 18 are each engraved with a gear that is not numbered on a flange portion formed at one opening edge, and the idle control cylinder 17 is formed with the gear. The open end (lower open end in FIG. 5) is inserted into the open end (upper open end in FIG. 6) in which the gear of the locking mechanism control cylinder 18 is formed, and can be rotated relative to each other. Is fitted.

  The idle and locking mechanism control cylinders 17 and 18 are rotatably supported by the lock box 19 as shown in FIG.

  As shown in FIG. 9, the cylinder stopper 21 is a thick plate material that is bent so that the cross-section is substantially square, and locks a pair of customer pieces 23, 23 that protrude from the lower edge of FIG. 9. It is supported by a support hole (not shown) formed in the side plate of the box 19 so as to be rotatable around a vertical rotation shaft as shown in FIG.

  Further, the upper end edge of the cylinder stopper 21 is cut into two forks to form the locking end edge 24 and the operation piece 25.

  On the other hand, the upper end of the lock box 19 is provided with an operation plate 26 that extends in the horizontal direction and is guided so as to be movable in a direction perpendicular to the front plate 27. One engagement notch 27 (see FIG. 10) is engaged with the operation piece 25.

  The U-shaped second engagement notch 28 formed at the outer end of the operation plate 26 forms a fixing screw 29 as shown in FIG. 11, that is, a cross hole that engages with the tip of the driver at one end, It engages with a groove at the other end of a fixing screw that is screwed into the screw hole of the front plate 27.

  Accordingly, the fixing screw 29 is pushed into the lock box, the locking end edge 24 of the fixed cylinder stopper 21 is moved out of the movement locus of the outer cylinder of the cylinder lock, and the lock unit is pushed into the lock box 19 and then the fixing screw. If the lock end edge 24 of the cylinder stopper is engaged with the lock groove 22 (see FIG. 1) by moving the cover 29 outward, the lock unit 1 remains locked in the axial direction in the lock box 19.

  On the other hand, the gears of the idle and locking mechanism control cylinders 17 and 18 are connected to the lock box 19 as shown in FIG. It meshes with the gear 21 in common.

  Therefore, when the gear portions of the idle and locking mechanism control cylinders 17 and 18 are meshed with the signal transmission gear 21 in common, the idle and locking mechanism control cylinders 17 and 18 are integrated with each other via the signal transmission gear 21. That is, it rotates in the state restrained mutually in the rotation direction.

  Further, the drive arm 33 (see FIG. 6) protruding radially in the outer cylinder portion of the locking mechanism control cylinder 18 is a driven notch formed at the inner end portion of the upper end edge of the dead bolt 34 as shown in FIG. 35, for example, the drive arm 33 swings within an angle range of 90 degrees in FIG. 12, thereby retracting the dead bolt 34 and unlocking the dead bolt 34 as shown in FIG. It protrudes from the plate 27 and is locked.

  Further, in the illustrated mechanism, as shown in FIGS. 5 and 6, the gear of the idle control cylinder 17 has more teeth than that of the locking mechanism control cylinder 18.

  Therefore, for example, when the cylinder lock 2 is locked and unlocked with a joint key, the idle and locking mechanism control cylinders 17 and 18 rotate integrally up to 90 degrees, but when the cylinder lock 2 exceeds 90 degrees, only the idle control cylinder 17 rotates further. The signal transmission gear 21 is moved to rotate, and a signal indicating that a signal generator (not shown) has been locked / unlocked with, for example, a key is utilized by using the extra rotation of the signal transmission gear 21. To be sent to.

  As shown in FIG. 12, one end of the thought spring device 36 is linked to the drive arm 33 of the locking mechanism control cylinder, and the other end of the thought spring device is linked to the control lever 37.
