Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lock device for an opening / closing lid of a traffic signal device having a cylinder lock that can be unlocked only by a special key, and in particular, it has a large opening / closing lid in which the lock tends to be unstable only with the cylinder lock. The present invention relates to a locking device for signal equipment.

[0002]

[Prior art]

 Various types of traffic signal devices are installed outdoors to display all traffic information. This traffic signal device requires an opening / closing lid for adjustment and maintenance of each device inside. A special cylinder lock specified by the National Police Agency is always installed on the opening / closing lid of the traffic signal equipment, and it can be opened and closed only by a key that matches this cylinder lock. The key custodian is registered and is prohibited from use by anyone other than the registrant.

[0003]

[Problems to be solved by the device]

 Some traffic signal devices are relatively small, but many devices that display road information are extremely large. In the case of a large traffic signal device, the storage case is naturally large and the opening / closing lid is accordingly large. A sealing member is provided on the mating surface between the opening / closing lid and the main body of the device to prevent rainwater and dust from entering the main body of the device. However, if the pressing force applied to the sealing member is insufficient, the sealing function will be reduced. When only the structure in which the opening / closing lid is closed and locked by the above-mentioned cylinder lock is used, it is difficult to secure the sealing property of the large opening / closing lid. For this reason, it is necessary to adopt a locking device other than the cylinder lock. In this case, it is meaningless to provide a special cylinder lock on the opening / closing lid in a structure in which the lock device can operate independently.

The present invention has been made in view of the above circumstances, and a large opening / closing lid is securely closed to ensure sealing performance, and the opening / closing lid is opened unless a special cylinder lock is operated. It is an object of the present invention to provide a lock device for a traffic signal device that is not possible and has an excellent aesthetic appearance.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a lock device for a lid of a traffic signal device, which is provided with a special cylinder lock determined by a rule, and a key insertion portion is provided on the surface side of the lid. The cylinder lock, which is exposed and has a locking portion inside the lid, a handle on which a grip portion is arranged on the front surface side of the opening / closing lid, and a rotating plate which connects a substantially central position to a rotation shaft of the handle. A connecting mechanism part for connecting between the rotating plates, and a locking device fixed to the connecting mechanism part and engaging with a locking part of the cylinder lock, the locking device being operated by a cylinder lock. Only the locking device of the traffic signal device is released from the engagement with the locking portion. Further, rods for barbs for fixing the opening / closing lid to the non-moving side of the equipment are extended and fixed in opposite directions to each other at both ends of the rotating plate, and are connected to the key insertion portion of the cylinder lock. The rotation axis of the handle is arranged on a line in the vertical direction.

[0006]

[Action]

 When the open / close lid is closed, the lock is attached to the lock of the cylinder lock. The locking tool is connected to the handle via the connecting mechanism and the rotating plate. Therefore, even if the handle is rotated, the opening / closing lid cannot be opened because the locking tool is fixed. On the other hand, when a predetermined key is inserted into the key insertion part of the cylinder lock and the locking part of the cylinder lock is moved in the opening direction, the locking tool becomes free. Therefore, the opening / closing lid can be opened and the handle can be rotated. The rotating plate is rotated by the rotation of the handle, the locking tool is separated from the locking portion, and the bar rods connected to both sides of the rotating plate move in the opening direction. Thereby, the opening / closing lid can be opened. To close the open / close lid, turn the handle with the key still inserted, insert the bar tacking rod into the equipment, and then remove the key from the cylinder lock to engage the lock on the cylinder lock. Put on and the lid will be locked. As described above, the large open / close lid can be locked securely and easily.

As shown in FIG. 1, an opening / closing lid 2 is supported by a hinge 4 on the front surface or the back surface of a main body case 3 of a traffic signal device so as to be openable and closable. A sealing member (not shown) is provided on the engaging surface between the opening / closing lid 2 and the main body case 3. The lock device 1 of this embodiment is attached to the back side of the opening / closing lid 2. As shown in FIG. 2, the cover member 6 of the key insertion portion 5 of the cylinder lock is exposed and arranged on the surface of the opening / closing lid 2, and the center of rotation of the handle 7 is arranged on the vertical line directly below the cover member 6. It The cover member 6 and the handle 7 are surface-plated and, as described above, are arranged along the vertical direction and thus have a design appearance. Although there are some conventional products that are similar to this arrangement, most of them are arranged diagonally to each other, and the design beauty is insufficient.

Next, the overall structure of the lock device 1 will be described with reference to FIGS. 3 to 5. On the upper side, a cylinder lock 8 is fixed and arranged on the back surface of the opening / closing lid 2. The cylinder lock 8 has the special key insertion portion 5 as described above, and when the key (not shown) is inserted into the key insertion portion 5 and rotated, the locking portion 9 reciprocates in the arrow direction. . On the other hand, the rotating shaft 10 of the handle 7 (FIG. 2) is rotatably fitted to the opening / closing lid 2, and the center point O thereof is arranged almost directly below the key insertion portion 5 of the cylinder lock 8. Further, the grip portion 11 of the handle 7 connected to the rotating shaft 10 is arranged on the front surface side of the opening / closing lid 2 as described above.

A substantially central position of a rotary plate 12 is connected and fixed to a rotary shaft 10 of the handle 7. One end side of bartacking rods 14 and 15 is connected to both ends of the rotating plate 12 via pins 13. The other ends of the rods 14 and 15 engage with the engagement holes (not shown) of the body case 3.

Next, the connecting mechanism 16 will be described. One end of the arm-shaped member 17 is pivotally supported on the rotating plate 12 by a screw 18 or the like. Further, the threaded portion 20 on the lower end side of the guide rod 19 is fixed to the other end side of the arm-shaped member 17 by a nut 21 or the like. On the other hand, the supporters 22 and 23 are fixed to the back surface side of the opening / closing lid 2. The supporters 22 and 23 are formed with long holes 24 and 25 for substantially restraining the movement of the guide rod 19 in the direction perpendicular to the paper surface of the drawing, and the guide rod 19 is arranged so as to penetrate the long holes 24 and 25. As described above, when the rotating plate 12 is rotated, the guide rod 19 is guided by the supporters 22 and 23 through the arm-shaped member 17 while being slightly inclined and moves up and down.

A base end side of the locking tool 26 is fixed to an intermediate portion of the guide rod 19. The tip side of the locking tool 26 is engaged with the locking part 9 of the cylinder lock 8.

Next, the operation of this embodiment will be described. FIG. 3 shows a state in which the opening / closing lid 2 is locked to the main body case 3, that is, a closed state of the opening / closing lid 2. In this case, the locking portion 9 of the cylinder lock 8 is fixed at the most protruding position, and the tip end side of the locking tool 26 contacts the lower surface thereof. The guide rod 19 is arranged almost vertically. Further, the rotating plate 12 to which the arm-shaped member 17 is connected is disposed in a substantially horizontal state, and the rods 14 and 15 in both directions thereof are fitted into the not-shown locking holes of the main body case 3 so that the opening / closing lid 2 is opened. The main body case 3 is brought into pressure contact with a sealing member (not shown). In the above state, the handle 7 cannot be rotated and the opening / closing lid 2 cannot be opened.

FIG. 6 shows the positional relationship of each part of the lock device 1 when the opening / closing lid 2 is opened. First, a key (not shown) is inserted into the key insertion portion 5 of the cylinder lock 8 and the key is rotated counterclockwise. As a result, the locking portion 9 is pulled in the direction of the arrow, and the locking between the locking portion 9 and the locking tool 26 is released. Next, when the handle 7 is gripped and rotated counterclockwise, the rotating plate 12 connected to the rotating shaft 10 rotates, and the arm-shaped member 17 and the guide rod 19 move accordingly. In addition, the bar tacking rods 14 and 15 also move in opposite directions, and are disengaged from the locking holes of the body case 3. The locking tool 26 fixed to the guide rod 19 moves to the position shown in FIG. 6 due to the connection position relationship of the respective constituent parts, and the locking tool 26 comes to a position where its tip end portion is almost in contact with the end surface of the locking part 9. However, the locking of both is released. Although the guide rod 19 is inclined, the guide rod 19 does not interfere with the supporters 22 and 23 due to the long holes 24 and 25 of the supporters 22 and 23. As described above, the opening / closing lid 2 is easily opened by pulling the handle 7 toward you.

Next, when the handle 7 is rotated in the clockwise direction, each component returns to the position shown in FIG. 3, and the key insertion portion of the cylinder lock 8 is rotated in the opposite direction (clockwise) to stop the lock. The part 9 projects, the locking tool 26 hits the lower surface of the locking part 9, and the closed state shown in FIG. 3 is restored. In this embodiment, since there are bar-tacking rods 14 and 15, even a large opening / closing lid 2 can be fixed on the main body case 3 side while maintaining the sealing property.

In the above embodiment, the connecting mechanism portion 16 has the illustrated structure, but it may have a link mechanism structure. Further, the structure of the locking tool 26 is not limited to that shown in the drawings. Further, the fixed connection structure of each component may be a structure that can be rotated by a pin.
