Description

Technical Field

[0001] The present invention relates to a handle device attached to a box for housing electric and electronic devices and a locking unit attached to the handle device.

Background Art

[0002] As a handle device attached to a box for housing electric and electronic devices, one using a cylinder lock is known. This handle device can be locked by operating the cylinder lock, and by locking it, a third party cannot operate the inside. However, when it is desired to operate remotely or to use an electronic lock that can be operated without a mechanical lock, it was necessary to replace the door itself or the cabinet itself. In contrast, Patent Document 1 discloses a technique that enables the replacement of the locking means inside the main body of the handle device.

[0004] However, in the technique disclosed in Patent Document 1, once the handle device is removed from the door and the structure such as the mechanism part is changed, it is necessary to reattach the handle device to the door, which has the problem of taking time and effort in the work.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The inventor of the present case has earnestly studied this point and tried to solve it. The problem to be solved by the present invention is to provide a handle device that can add functions without being removed from the door.

Means for Solving the Problems

[0006] To solve the above problems, the present invention provides a handle device equipped with a handle that can be operated to move the door of a box for storing electrical and electronic equipment from a locked state to an unlocked state, comprising a locking member capable of restricting the operation of the handle by locking it in place, and a main body case that houses the locking member, wherein a locking unit that allows switching between a locked state in which the handle is locked and an unlocked state in which the locking state is released can be attached from the outside of the back side of the main body case by operating the locking member.

[0007] Furthermore, it is preferable that the locking member is pivotally supported by a pivot inside the main case, and that when a detachable lock unit is attached, the locking member can be rotated so that the pivot is the center by moving the operating part of the lock unit, thereby switching from a locked state to an unlocked state.

[0008] Furthermore, it is preferable to provide the operated part such that a portion of it is exposed on the outside of the main body case, and to configure the device so that the locking member is rotated so that the pivot point is the center by moving the operating part of the lock unit which is engaged with the operated part on the outside of the main body case, thereby enabling a switch from a locked state to an unlocked state.

[0009] Furthermore, it is preferable to have a configuration that includes a cylinder lock with a lock hole on the front side, and a link member that moves a locking member in conjunction with the operation of the cylinder lock, and that allows the locking member to be rotated so that its pivot point is the center by moving the operating part of the lock unit, thereby switching from a locked state to an unlocked state.

[0010] Furthermore, it is preferable that the lock unit attached to the handle device comprises a thin section and a thick section, with an operating section for operating a locking member provided in the thin section and a mechanism for moving the operating section provided in the thick section.

[0011] Furthermore, it is preferable that the lock unit be an electronic unit capable of receiving signals from an external source and operating the locking mechanism. [Effects of the Invention]

[0012] This invention makes it possible to create a handle device that allows for the addition of functions without having to remove it from the door. [Brief explanation of the drawing]

However, a power connection part is provided at the tip of the lock unit, and an openable and closable shutter is provided at a position facing the power connection part.

Embodiments for Carrying Out the Invention

[0014] The following describes embodiments for carrying out the invention. As can be seen from Figures 1 to 7, the handle device 1 of this embodiment is equipped with a handle 12 that can be operated to move the door 82 of the electrical and electronic equipment storage box 8 from a locked state to an unlocked state. The handle device 1 is equipped with a locking member 14 that can restrict the operation of the handle 12 by locking it, and a main body case 11 that houses the locking member 14. A locking unit 5 that can be mounted on the outside of the back side of the main body case 11 can be mounted by operating the locking member 14 to switch between a locked state in which the handle 12 is locked and an unlocked state in which the locked state is released. Therefore, the handle device 1 is equipped with a locking unit 5 that can be operated by locking the handle 12 and an unlocked state in which the locked state is released.

[0015] The handle device 1 is capable of being fitted with a lock unit 5 to which a locking function can be added, and it is preferable that the lock unit 5 be an electronic unit capable of receiving signals from the outside and operating the locking member 14. However, the lock unit 5 may also be capable of performing other functions.

[0016] Furthermore, by attaching the lock unit 5 to the handle device 1, the handle structure gains additional functionality compared to the handle device 1 alone. In this case as well, since the lock unit 5 is located on the back side of the door 82, the appearance of the electrical and electronic equipment storage box 8 does not need to be changed.

[0017] Here, we will describe the electrical and electronic equipment storage box 8 to which the handle device 1 of this embodiment is attached. The electrical and electronic equipment storage box 8 comprises a housing body 81 for housing electrical and electronic equipment, and a door 82 that covers the opening of the housing body 81. The handle device 1 is attached to the door 82 and can prevent the door 82 attached to the housing body 81 from opening.

[0018] The basic configuration of the handle device 1 in this embodiment is similar to that of what is generally called a flat handle, and includes a container-shaped main case 11 fixed to the door 82 and a handle 12 that can be gripped. The handle 12 does not normally need to be moved and is therefore stored in the main case 11. For example, to open the door 82 from a closed state, the handle 12 is rotated to operate the tab 13 formed at the tip of the handle 12. However, if the handle 12 is stored in the main case 11, the handle 12 must be pulled out and then rotated to operate the tab 13. (See Figures 1 and 2).

[0019] Furthermore, in addition to the handle 12 that the user grasps and rotates, the handle device 1 of this embodiment also includes an operating mechanism housing 11a that houses an operating mechanism 15 that pivotally supports one end of the handle 12 and operates the tongue 13, a locking member 14 that locks to the other end of the handle 12 and restricts the operation of the handle 12, and a locking mechanism housing 11b that houses the locking mechanism of the cylinder lock 16 (see Figures 3 and 4). However, the handle device 1 does not need to have all of these components. In this embodiment, the operating mechanism housing 11a and the locking mechanism housing 11b are provided on one end and the other end of the main body case 11, respectively.

[0020] In this embodiment, the locking piece 12a provided at the end of the handle 12 and the locking member 14 housed in the lock mechanism housing 11b can be locked together. When they are locked together, the handle 12 cannot be raised, and therefore the tab 13 cannot be operated. In order to move the handle 12 so that the tab 13 can be operated, the locking of the locking piece 12a and the locking member 14 of the handle 12 is released, the handle 12 is raised, and the handle 12 is rotated while it is raised. The locking member 14 is pivotally supported inside the handle device 1 and is biased by a spring 17 in the direction of locking with the handle 12.

[0021] In this embodiment, the locking member 14 is pivotally supported on a pivot 22 inside the main body case 11, and the locking member 14 is biased in the locking direction by a spring 17. More specifically, a substantially V-shaped spring 17, which can be biased to open both ends, is attached to the pivot 22 of the locking member 14, with the first arm 17a of the spring 17 in contact with the locking member 14 and the second arm 17b in contact with the inner surface of the main body case 11 (see Figures 5 and 6). Since the second arm 17b is in contact with the inner surface of the main body case 11 and does not move, when the first arm 17a and the second arm 17b of the spring 17 move apart, the first arm 17a moves the locking member 14 in the locking direction. In this way, the locking member 14 is biased in the locking direction by the spring 17.

[0022] When the locking member 14 rises, the first arm 17a moves closer to the second arm 17b. When this movement occurs, the elastic force causes a stronger force to act on the first arm 17a, attempting to move the locking member 14. When the locking member 14 is released from its immobile state, the biasing force of the spring 17 causes the locking member 14 to return to its fallen position.

[0023] In this embodiment, the handle device 1 is equipped with a cylinder lock 16. The cylinder lock 16 allows the locking member 14 to be operated by inserting a key into the lock hole 16a and turning it. When the handle 12 is to be raised, operating the cylinder lock 16 causes the locking member 14 to rotate, releasing the locking state between the handle 12 and the locking member 14, and making it possible to raise the handle 12.

[0024] In this embodiment, the locking member 14 rotates when switching from the locked state to the unlocked state, but the locking member 14 may also slide to switch between the locked and unlocked states. However, if the locking member 14 rotates when switching from the locked state to the unlocked state, it is possible to increase the biasing force used to lock the locking member 14 and the handle 12 while suppressing the movement of the locking member 14.

[0025] As can be understood from these descriptions, the handle device 1 is preferably configured such that the locking member 14 is pivotally supported on the pivot 22 inside the main body case 11, and when the detachable lock unit 5 is attached, the locking member 14 can be rotated so that the pivot 22 is the center by moving the operating part 51 of the lock unit 5, thereby switching from a locked state to an unlocked state.

[0026] In this embodiment, an operable part 18 capable of moving the locking member 14 is provided on the rear side of the handle device 1 (see Figures 7 and 8). A lock unit 5, which includes an operating part 51 for operating this operable part 18, is attached to the outside of the rear side of the main body case 11, and the locking member 14 can be operated by operating the lock unit 5. Therefore, a locking function can be added without removing the handle device 1 from the door 82. Furthermore, the lock unit 5 in this embodiment is configured to be securely fixed from the outside of the main body case 11 using screws and a fixing part 11c provided on the main body case 11 of the handle device 1 (see Figure 7).

[0027] Incidentally, if a part of the operated part 18 is exposed to the outside of the main body case 11, or more specifically, if a part of the operated part 18 protrudes to the outside of the main body case 11, it becomes easier to move the operated part 18 without using the lock unit 5. For this reason, for example, if the lock unit 5 does not work, it may be possible to remove the lock unit 5 and move the operated part 18 by grasping it with pliers or your fingers.

[0028] As can be understood from the above, it is preferable to provide the operated portion 18 such that a part of it is exposed to the outside of the main body case 11, and to move the operating portion 51 of the lock unit 5 which is engaged with the operated portion 18 on the outside of the main body case 11, thereby rotating the lock member 14 so that the pivot portion 22 is the center, and making it possible to switch from a locked state to an unlocked state.

[0029] The lock unit 5 can be exemplified by an electronic unit equipped with a motor 52 and a solenoid that operate in response to an external signal input. For example, the electronic unit may include an operating unit 51 that is rotatable for rotating the operated part 18, a motor 52, a mechanism 53 that is rotatably attached to the tip of the motor 52, and an interlocking unit 54 that connects the operating unit 51 and the mechanism 53 (see Figures 9 and 10). With such a configuration, even if the motor 52 is positioned away from the operating unit 51, the motor 52 can be used to rotate the operating unit 51 and the operated part 18.

[0030] In the examples shown in Figures 9 and 10, a bent plate member is provided with a portion for fixing the operating unit 51 and a portion for supporting one end of the motor 52. In addition, a separate bent plate member is provided with a portion for supporting the other end of the motor 52. These members formed by bending the plate are fixed in place so as to be able to firmly support the motor 52.

[0031] Furthermore, the shaft of the motor 52 and the rotational axis of the operating unit 51 are configured to be separated in a direction perpendicular to the direction in which the shaft of the motor 52 extends. Therefore, it is not necessary to position the motor 52 on the operating unit 51 side as seen from the operated unit 18.

[0032] The lock unit 5 of this embodiment comprises a relatively thin section 5a and a thicker section 5b. The thin section 5a is equipped with an operating section 51 used to move the locking member 14. The thicker section 5b of this embodiment houses a motor 52 that operates the operating section 51, a mechanism 53, and a circuit board that receives signals from an external source to operate the motor 52 or supply power.

[0033] When the lock unit 5 is attached to the handle device 1, it is preferable that the amount by which the lock unit 5 protrudes into the housing body 81 is suppressed, so that the lock unit 5 has a thin portion 5a and a thick portion 5b, with an operating part 51 for operating the locking member 14 on the thin portion 5a and a mechanism 53 for moving the operating part 51 on the thick portion 5b.

[0034] Furthermore, in this embodiment, the lock mechanism housing 11b and the thickened portion 5b are arranged adjacent to each other, but the thickened portion 5b is positioned to face a different surface than the surface facing the thinned portion 5a of the lock mechanism housing 11b. This allows for the addition of a new locking function while suppressing the amount of protrusion to the rear side of the handle device 1.

[0035] It is preferable to allow the lock unit 5 to be attached to the handle device 1 in different orientations. For example, it is preferable to configure the position of the thick portion 5b relative to the thin portion 5a to be selectable from two or more options: left, right, up, or down (see Figures 7 and 11). Of course, it is preferable to configure the lock unit 5 to be attached to the handle device 1 so that the position of the thick portion 5b relative to the thin portion 5a can be selected from any of the left, right, up, or down options. In this way, the mounting orientation of the lock unit 5 can be determined considering the position of equipment inside the housing body 81.

[0036] Incidentally, the locking member 14 housed in the lock mechanism housing 11b is rotatable around the pivot 22 (see Figure 12). The locking member 14 has a locking piece 14a at one end that engages with the handle 12, and an open end 14b at the other end. In this embodiment, the handle device 1 is equipped with a cylinder lock 16, and the locking member 14 can be moved by inserting a key into the lock hole 16a of the cylinder lock 16 and turning it. To enable this, the embodiment is equipped with a linking member 19 that is linked to the rotation of the cylinder lock 16.

[0037] The projection 16b on the cylinder lock 16 and the engaging portion 19a of the link member 19 are capable of engaging. Furthermore, a retaining portion 21 provided on the inner surface of the lock mechanism housing portion 11b is adjacent to the link member 19, making it possible to restrict the direction of movement of the link member 19 (see Figure 13). Therefore, by inserting a key into the cylinder lock 16 and turning it, the projection 16b of the cylinder lock 16 moves, allowing the link member 19 to slide. In this embodiment, a regulating rod 23 is positioned so as to be able to contact the link member 19 in order to prevent the link member 19 from sliding too far (see Figure 5).

[0038] Furthermore, the link member 19 can contact the open end 14b of the locking member 14, and by moving the link member 19, the locking member 14 can be rotated, releasing the lock between the handle 12 and the locking member 14. This is because the open end 14b of the locking member 14 is pushed by the pressing portion 19b of the link member 19 and rotates. The retaining portion 21 is adjacent to the locking member 14 and can restrict the direction of movement of the locking member 14.

[0039] As can be understood from these descriptions, it is preferable to have a configuration that includes a cylinder lock 16 with a lock hole 16a on the front side, and a link member 19 that moves a locking member 14 in conjunction with the operation of the cylinder lock 16, and that allows switching from a locked state to an unlocked state by moving the operating part 51 of the lock unit 5 to rotate the locking member 14 so that the pivot portion 22 is the center.

[0040] By the way, in this embodiment, the engaging portion 19a of the link member 19, into which the projection 16b of the cylinder lock 16 engages, extends diagonally. The engaging portion 19a shown in Figure 14 is an elongated recess into which the projection 16b of the inserted cylinder lock 16 is inserted.

[0041] By inserting a key into the cylinder lock 16 and turning it, the projection 16b of the cylinder lock 16 rotates. This movement causes movement in the left-right and up-down directions. However, because the lock is equipped with an engaging portion 19a that has an elongated hole shape extending diagonally and a retaining portion 21 that can suppress the left-right movement of the link member 19, the movement of the projection 16b allows the link member 19 to move mainly only in the up-down direction (see Figures 13 to 15).

[0042] In this embodiment, the engaging portion 19a, which has an elongated hole shape, is configured such that its length in the shorter direction is approximately twice the width of the projection 16b, so that when the link member 19 is moved by the operation of the operated portion 18, which will be described later, the projection 16b does not obstruct the movement of the link member 19.

[0043] Furthermore, the cylinder lock 16 is configured such that if it is rotated in the reverse direction (returned to its original position), the link member 19 returns to its original position due to the biasing force of the spring 17.

[0044] In this embodiment, the link member 19 can also be operated by the movement of the operated part 18. The operated part 18 in this embodiment is equipped with a projection 18a that can press against the link member 19 (see Figure 16). By rotating the operated part 18 with the operating part 51, the projection 18a presses against and moves the link member 19, thereby moving the locking member 14. By performing this movement, the locking member 14 and the handle 12 can be switched from a locked state to an unlocked state (see Figure 17). In this embodiment, once the locking member 14 has been tilted to a predetermined angle, an arc-shaped surface 19c is provided on the part that contacts the projection 18a to prevent the locking member 14 from tilting any further.

[0045] As described above, rotating the operated part 18 in the reverse direction (returning it to its original position) will return the link member 19 to its original position due to the biasing force of the spring 17. Although Figure 17 shows the change in state when the operated part 18 is rotated counterclockwise, the same movement can be achieved by rotating it clockwise.

[0046] Incidentally, the handle device 1 of the embodiment is fixed to the door 82 by sandwiching it between a flange portion 11a positioned on the front side of the door 82 and a mounting portion 41 positioned on the back side of the door 82. In the example shown in Figure 18, the mounting portion 41 is configured as a separate component from the lock unit 5, but it is not necessary for the lock unit 5 and the mounting portion 41 to be separate components; the lock unit 5 may also be equipped with the mounting portion 41 (see Figure 19). In this case, the number of parts can be reduced and the workability when installing the lock unit 5 can be improved.

[0047] In the example shown in Figure 7, the operating part 51 of the lock unit 5 is connected to the operated part 18, which is partially exposed from the main case 11. However, as can be seen from Figure 20, the lock unit 5 may be configured so that at least a part of the operating part 51 is exposed, and it is connected to the operated part 18 inside the main case 11.

[0048] Furthermore, although the example described above includes a link member 19, the structure may be configured without the link member 19, with the operated part 18 directly contacting the locking member 14 during operation. In this case, the handle device 1 can be configured without a cylinder lock 16 (see Figure 21).

[0049] By the way, in the examples shown in Figures 7 and 11, the lock unit 5 is mounted on the main body case 11 and the thick portion 5b is positioned adjacent to the handle device 1. However, it is also possible to provide a recessed space 11b in the main body case 11 and insert the lock unit 5 into that recessed space 11b. In this case, the lock unit 5 can be configured to directly contact and operate the locking member 14. For example, if a cylinder lock 16 that can operate the locking member 14 is not provided, the position where the cylinder lock 16 is normally located can be made into a recessed space 11b into which the lock unit 5 can be fitted (see Figures 22 and 23).

[0050] Furthermore, the lock unit 5 equipped with the cylinder lock 16 may be configured such that the cylinder lock 16 is placed in the recessed space 11b. In any case, it is preferable to have multiple types of lock units 5 available so that the lock unit 5 can be selected according to the function to be added. For example, if a function that allows the use of a cylinder lock 16 is to be added, the first lock unit can be selected and installed, but if a function that allows the use of an electronic lock involving electrical operation is to be added, the second lock unit can be selected and installed.

[0051] If the lock unit 5 is to be equipped with an electronic lock function, it may be configured to have an openable and closable shutter 61 on the front side and a power connection part 62 (such as a USB connector) to which a power supply can be connected. In this way, in the event of a power outage, the shutter 61 can be opened and the battery connected to the power connection part 62 to supply power and operate the handle 12.

[0052] Although the present invention has been described above with reference to the embodiments described, the present invention is not limited to the above embodiments and can be implemented in various forms. [Explanation of symbols]
