Description

  The present invention relates to a handle device incorporated in, for example, a cabinet used in a data center.

  A handle device having a lock mechanism is attached to a cabinet door used in a data center or the like. The handle device includes a handle handle pivotally attached to the handle body and a locking hook interlocked with the handle handle. When the handle handle is raised from the handle body, the locking hook is unlocked. When the handle is brought to a position where it is brought into close contact with the handle main body, the locking hook becomes the locking position. For this reason, if the handle handle is locked in the tilted position, it can be locked so that the door cannot be opened.

  Therefore, conventionally, a lock means for locking the handle handle at a position in close contact with the handle body is incorporated in the handle body. As this locking means, a cylinder lock as shown in Patent Document 1 and a solenoid type electric lock are generally used. The cylinder lock mechanically locks the handle handle, and the electric lock operates the solenoid by an electric signal to lock the handle handle. It is common for an electric lock to be a combination lock that can be unlocked by a cylinder lock even in a situation where the electric lock cannot be operated due to a power failure or the like.

  Which locking means to employ from the security aspect in a data center or the like is often determined in relation to other peripheral equipment, and differs depending on the user. It is possible to provide a handle handle consisting only of a cylinder lock by removing components such as a solenoid from the composite lock. However, since the strength performance (seismic standards, etc.) of the portion of the handle device excluding the lock means is the same, it is desirable for the handle device manufacturer to share parts other than the lock means from the viewpoint of cost reduction.

  However, when the electric lock is incorporated, the operation button needs to be provided on the surface of the handle body, whereas when only the cylinder lock is incorporated, it is not necessary. As described above, the structure of the handle main body is different between the electric lock and the cylinder lock, and there is a problem in that it is impossible to make common parts that occupy a large part of the handle device, and it is necessary to manufacture two types of handle devices. It was.

  The object of the present invention is to solve the above-mentioned conventional problems, and to select either a cylinder lock or an electric lock as a locking means, and to make most other parts common only by recombination of the locking means. It is providing the handle device which can do.

  The present invention, which has been made to solve the above problems, includes a handle handle that can be raised and lowered with respect to the handle body, a locking hook that is interlocked with the handle handle, and a position where the handle handle is in close contact with the handle body. A handle device having a lock means for locking, wherein a cylinder lock that mechanically locks the handle handle and an electric lock that locks the handle handle by a solenoid can be selected as the lock means. Has a window hole. When the cylinder lock is selected as the locking means, the lock state indicator is exposed to this window hole, and when the electric lock is selected, the unlocking operation button is exposed to this window hole. It is characterized by not.

  Note that the display unit in the locked state is preferably connected to the base member interlocked with the locking / unlocking operation of the cylinder lock. It is a slide piece that moves in conjunction with the window hole, and can be differently colored with the ridgeline as a boundary.

  In the handle device of the present invention, a cylinder lock that mechanically locks the handle handle and an electric lock that locks the handle handle by a solenoid can be selected as the locking means. Since the display unit in the locked state is faced and the operation button is faced when the electric lock is selected, the parts other than the lock means can be shared without waste. Since the display unit in the locked state is connected to the base member that interlocks with the locking / unlocking operation of the cylinder lock, the locked state can be displayed at a position away from the cylinder lock 30. Further, when the cylinder lock is selected, there is an advantage that it is easy to visually recognize whether it is in the locked state or the unlocked state by the display portion that can be seen from the window hole of the handle handle.

It is a perspective view which shows an internal structure. It is a perspective view which shows an internal structure. It is explanatory drawing of a display part.

Embodiments of the present invention will be described below.
FIG. 1 is an external perspective view when a solenoid and a cylinder lock are incorporated as locking means in the handle device of the present invention to form a composite lock, FIG. 2 is a perspective view showing the internal structure, and FIGS. 3 and 4 show the internal structure. It is sectional drawing. In these drawings, 1 is a hollow handle body fixed to a door of a cabinet or the like, and 2 is a handle handle that can be raised and lowered with respect to the handle body 1. A housing 3 is fixed inside the hollow handle body 1 by appropriate means such as press fitting.

  The housing 3 is a frame-like body having a rectangular window hole, and the base end portion of the handle handle 2 is pivotally attached by a shaft 4. In addition, a pair of locking hooks 5 are pivotally attached to the housing 3 by shafts 6 on both sides of the shaft 4. As shown in FIG. 3, each locking hook 5 is bent to the opposite side of the shaft 4, and one end of a link 8 is pivotally attached to the intermediate portion by a pin 7. The other end of the link 8 is a handle handle. Two base ends are connected by a pin 9. These locking hooks 5 engage with a locking piece (not shown) on the main body side such as a cabinet and have a role of locking the door.

  As shown in FIG. 4, when the handle handle 2 is lifted about the shaft 4 and is raised from the handle body 1, the pair of locking hooks 5 are rotated by the link 8 in a direction approaching the shaft 4 and unlocked. It becomes a state. Conversely, as shown in FIG. 3, when the handle handle 2 is closed so as to be in close contact with the handle body 1, the pair of locking hooks 5 rotate in a direction away from the shaft 4 to be locked. Thus, locking and unlocking the door with respect to the main body of the cabinet or the like is not a main part of the present invention, and thus detailed description thereof is omitted.

  As shown in FIGS. 3 and 4, the distal end portion of the handle handle 2 far from the shaft 4 is bent toward the handle body 1, and a concave engaging portion 10 is formed on the inside thereof. A lock member 11 that locks the handle handle 2 so that it cannot be opened is pivotally supported by a lower shaft 12 in the vicinity of the end of the housing 3. The lock member 11 includes an engaging claw 13 that engages with the concave engaging portion 10 of the handle handle 2 at the distal end. Therefore, the handle handle 2 is locked in the engaged state shown in FIG. 3, and the handle handle 2 is lifted unless the lock member 11 is tilted to disengage the engaging claw 13 from the concave engaging portion 10 of the handle handle 2. It is not possible. In this embodiment, the lock member 11 is pivotally supported by a base member 14 slidably held on the back surface of the housing 3.

  A solenoid 20 for rotating the lock member 11 about the shaft 12 is provided at a position adjacent to the lock member 11 on the housing 3. The plunger 21 of the solenoid 20 is connected to the central hole of the lock member 11 by a pin 19 and a pin 19. When an operation button 43 provided on the surface of the handle 2 is pressed, an electric signal for unlocking is input. As a result, when the solenoid 20 sucks the plunger 21, the lock member 11 rotates as shown in FIG. 6 to bring the handle handle 2 into an unlocked state. The control signal is maintained for a certain time by a timer relay or the like, and when released thereafter, the plunger 21 of the solenoid 20 returns to the original position by the force of the spring built in the solenoid 20.

  A cylinder lock 30 is disposed on the opposite side of the solenoid 20 across the lock member 11 on the housing 3. As shown in FIG. 4, the cylinder lock 30 is provided with a protrusion 32 at a lower eccentric position, and the cylindrical portion 31 is accommodated in the cylindrical portion 33 of the housing 3, but the protrusion 32 is an end portion of the base member 14. It is fitted in the long hole 34 formed in.

  Therefore, unless the cylinder lock 30 is operated, the base member 14 does not slide, and the lock member 13 is rotated by the solenoid 20. However, in the case of a trouble in the electrical system or a power failure, the unlocking by the solenoid 20 becomes impossible. In that case, the key is inserted and the cylinder lock 30 is rotated. As a result, the base member 14 slides from the state of FIG. 5 to the state of FIG. 6 in the right direction of the drawing, and the lock member 11 is pushed by the holding piece 35 of the housing 3 and rotates counterclockwise in the drawing to lock. Can be released mechanically.

  As described above, when the solenoid 20 is incorporated as the locking means, it is necessary to send an unlocking electrical signal to the solenoid 20 in a state where the handle 2 is closed and closed. Therefore, as shown in FIG. 4, a window hole 40 is formed on the front surface of the handle handle 2, and a lever 41 is pivotally attached to the back surface of the handle handle 2 by a pin 42. It faces and is projected to the surface side by the elastic force of the spring 44. Further, a switch 46 is provided in the housing 3 at a position corresponding to the protrusion 45 on the back surface of the lever 41 when the handle handle 2 is tilted as shown in FIG. With this structure, when the operation button 43 protruding from the window hole 40 is pressed with a fingertip, the switch 46 is pressed down and an electric signal for unlocking is input to the solenoid 20. Since the solenoid 20 is excited by pressing the operation button 43 after turning on the control power for operating the steering wheel in the central monitoring room or the like, the energizing time to the solenoid 20 can be shortened, and the component life can be shortened. Made it possible to extend.

Next, a case where only a cylinder lock is incorporated as a lock means will be described.
7 is an external perspective view, FIG. 8 is a sectional view thereof, and FIGS. 9 and 10 are perspective views showing the internal structure.

  When only the cylinder lock is incorporated as the locking means, the solenoid 20 and its control circuit board are not required. Therefore, in this embodiment, as clearly shown in FIG. 10, an inverted L-shaped indicator 50 is attached to the end of the base member 14 that slides in conjunction with the operation of the cylinder lock 30. The indicator 50 includes a rising arm 51 to the front surface side of the handle main body 1 and a plate-like portion 52 extending in parallel with the back surface of the handle handle 2 in a tilted state. On the surface of the plate-like portion 52, a display portion 53 is formed at a position facing the window hole 40 of the handle handle 2 described above.

  The display portion 53 is obtained by painting both sides of a protrusion having a triangular cross section in different colors, for example, red and blue. With such a configuration, when the display unit 53 that slides integrally with the base member 14 is viewed from the window hole 40 as shown in FIG. 11, only one of the colors can be seen, and the slide stroke Even if is small, it becomes easy to visually recognize whether the locked state or the unlocked state.

  In the handle device of this embodiment, the handle handle 2 is locked only by the cylinder lock 30. That is, by inserting the key and rotating the cylinder lock 30, the base member 14 takes one of the positions shown in FIG. 5 and FIG. 6, thereby rotating the lock member 11 and turning the handle handle 2. Will be locked or unlocked.

  As described above, in the handle device of the present invention, either the solenoid 20 or the cylinder lock 30 can be selected as the handle handle lock means, and when only the cylinder lock 30 is selected, the window hole 40 of the handle handle 2 is selected. When the electric lock with the solenoid 20 is selected when the display unit 53 is faced, the operation button 43 is faced, so that the handle body 1, the handle handle 2, and the lock hook which are parts other than the locking means 5, many parts such as the housing 3 and the lock member 11 can be shared without waste. Moreover, since the display part 53 is connected to the base member interlocked with the locking / unlocking operation of the cylinder lock 30, the lock state can be displayed in the window hole 40 at a position away from the cylinder lock 30. Further, when only 30 is selected as the cylinder lock, there is an advantage that it is easy to visually recognize whether it is in the locked state or the unlocked state by the display portion 53 that can be seen from the window hole 40 of the handle handle 2.
