By simply attaching to the front side of the cylinder lock, it can be set in the recessed part by immersing and setting, and you can change the display color and adjust the appearance of the display body before assembling to the lock body. It can be easily manufactured by rotating, and can be manufactured as one in which the structure of the retracting mechanism itself and the assembly structure of the display body to the cylinder lock device itself are simplified. As with the existing connecting body used when there is a space between the cylinder lock and the lock body, the spline shaft part is also connected to the lock body provided on the door body by spline engagement. It can be easily assembled just by wearing it.

FIG. 2 is a front view, a side view, and a cross-sectional view of the cylinder lock device in a state in which the opening/closing lid is opened and a state in which the display body is projected, respectively, in (A) to (F), and FIG. [Fig. 6] is a perspective view of the cylinder lock device with an opening/closing lid opened to project a display body, and ( B) is a perspective view of a connecting body including a cam portion.
As shown in these drawings, the cylinder lock device 3 comprises a lock body 2 provided in the door body 1, a cylinder case 31 that is attached to the door body 1, it is furnished to the cylinder casing 31, tablets A cylinder lock 32 in which the dead bolt 21 of the main body 2 is interlockingly linked so that it can be retracted by a locking/unlocking operation, and a lock/unlock state of the cylinder lock 32 is switched and displayed according to the locking/unlocking operation of the cylinder lock 32. The display unit 4 is provided on the front surface side, and the opening/closing lid 5 is provided so as to be openable/closable so as to cover the front surface portion of the cylinder case 31.

On the other hand, the cover piece 43 is formed in a thin plate ring shape with an outer diameter slightly larger than the outer diameter of the display body 4, and when the display body 4 is retracted, the cover piece 43 is in close contact with the front edge of the cylinder case 31 (concave portion 313). Further, together with the cover piece 43, the display body 4 is provided with an opening/closing lid 5 rotatably supported on the upper end of the front surface portion thereof so as to cover the front surface portion of the cylinder case 31. Dust, dust, rainwater, or dust in the factory facility does not enter the gap between the outer periphery of the display body 4 and the concave portion 313 or the central space of the concave portion 313 in a sealed structure. That is, the opening/closing lid 5 has a trapezoidal bulging portion 51 whose back side slightly protrudes toward the inner peripheral side of the display body 4 (cover piece 43 ), and the entire outer diameter thereof is the outer diameter of the cover piece 43. It is formed in a disk shape having an outer diameter slightly larger than that, and as shown in FIG. 2D, is rotatably supported by the support shaft 52 in the groove 314 of the cylinder case 31. A coil spring 52a provided on the support shaft 52 is urged and mounted in a direction in which the surface of the cover piece 43 is constantly pressed against the surface of the cover piece 43. That is, the opening/closing lid 5 is configured to be integrated with the display body 4 so that the opening/closing lid 5 can be opened/closed and can be opened/closed by 360 degrees independently of the appearance/withdrawal operation of the display body 4. By squeezing the outer peripheral end with a finger and rotating it, the bulging portion 51 rides on the inner peripheral corner portion of the cover piece 43 against the inclination of the outer periphery thereof, and is brought into a state of being pressed against the cover piece 43, The key is inserted into the hole 321 and rotated to an arbitrary position where the key can be inserted and held in the open state. Although the cover piece 43 is formed as a hermetically-sealing member, it may be simply a sealing material for covering the front surface of the display body 4 as a cover, or the front surface may be exposed to function as a display area without using this member. In that case, when the display body 4 is retracted, the outer peripheral edge portion of the open/close lid 5 may be pressed against the front peripheral edge of the concave portion 313 instead of the front surface of the display body 4 to seal the display body 4.

Further, the cam portion 34 has one end formed on the cylinder tail piece 322 and the other end formed on the outer peripheral edge portion of the connecting body 33 that is rotatably connected and engaged with the lock body 2, so that a separate cam member is interposed. It is possible to reduce the number of parts and the number of assembling steps without needing to do so, and the display body 4 is mounted on the driven shaft 41 guided and supported in the cylinder case 31 in a state where the tip end thereof is in contact with the cam surface 34a. On the other hand, by simply attaching from the outside to the front side of the cylinder lock 32, the cylinder lock 32 can be immersed and set in the recessed portion 313, and different display colors can be changed and the appearance/disappearance of the display body 4 can be adjusted. It can be easily performed by rotating the spline shaft portion 331 before assembling into the lock mechanism, and simplification of the structure of the retracting mechanism itself and the assembling configuration of the display body 4 to the cylinder lock device 3 itself. The lock body 2 can be manufactured as an improved one, and is used when there is a separation space between the cylinder lock 32 and the lock body 2 for the lock body 2 provided on the door body 1. Similar to the existing connecting body, the spline shaft portion 331 can be easily assembled only by connecting and attaching by spline engagement.

In addition, the connecting body 33 allows the cylinder lock 32 and the lock body to selectively display the display body 4 in either the unlocked state or the locked state in response to the locking/unlocking operation of the cylinder lock 32. Since it is configured such that it can be interposed between the display shaft 4 and the drive shaft 2, the tip of the driven shaft 41 is located at the valley of the cam surface 34a, and the display body 4 is set in the recessed portion 313 of the cylinder case 31 by a working process. in, Kakarigokoma 6 and the engagement between the cylinder tail piece 322, for example, when it is desired to protrude displayed in unlocked state, the cylinder lock 32 to FIG. 4 (a) are shown connected in the locked state 33 When assembling and setting, and when it is desired to display the display body 4 in a locked state from this state, the connecting body 33 is rotated 180 degrees to bring the cylinder lock 32 into the unlocked state shown in FIG. 4(B). After assembling and setting, it is sufficient to prevent the end cap 31a from coming off, and it is possible to easily perform selection switching of the protruding display state of the display body 4 without changing any member or assembly procedure. It is possible to promptly respond to the demands of the installation site without increasing the cost. It is also possible to switch the selection of the protruding display state of the display body 4 on-site even after the assembling by removing the screwed end cap 31a.
The lock body 2 may be assembled by connecting the spline shaft portion 331 by engaging the spline shaft portion 331 with the dead bolt 21 in the protruding or retracted state according to the protruding display state of the display body 4.

Further, the display body 4 is immersive in the locked state of the lock body 2 and is projected and displayed in the unlocked state in the door body 1 in which entry into the room and door opening operation are restricted, and the door body 1 is always managed to be closed. Is set to. For example, a door 1 such as an entrance/exit to a room or an inspection door such as a unit box in a place where entry of an ordinary person or contact with equipment is regulated is constantly closed, for example, at intervals of several days. It is often the case that a relatively short time period is allocated at intervals of several hours a day, and the unlocked state is set only while the manager or worker enters and leaves the room and performs inspection work. This operation of unlocking is performed by the locking/unlocking operation of the cylinder lock 32. In the present embodiment, the key is inserted after the key is inserted into the key hole 321 with the opening/closing lid 5 opened, and then the key is pressed. It is operated by the procedure of pulling out and closing the opening/closing lid 5. At this time, the display body 4 is projected and displayed, and the administrator and the operator can be made aware that the cylinder lock 32 is in the unlocked state. Can be done easily.
