  Embodiments of the present invention will be described below. 1 to 6 show a first embodiment. In FIG. 1, reference numeral 1 denotes a box body of an electric / electronic equipment storage box, and 2 denotes a door hinged to the box body. A handle device is provided on the opposite side of the door 2 from the hinge. The handle device includes a circular handle main body 3 formed integrally with the door, and a rotary handle 5 that can be rotated around the rotary shaft 4 inside the handle main body 3.

  As shown in FIG. 2, a rotating plate 7 having a locking piece 6 and locking rods 8 and 8 having ends connected to the rotating plate 7 are provided on the back surface of the rotating shaft 4. The door 2 can be locked and unlocked by rotating 5. However, it goes without saying that these locking mechanisms are well known and can be changed as appropriate.

  In order to restrict the operation of the rotary handle 5, the handle body 3 is provided with a cylinder lock 9. As shown in FIG. 4, the cylinder lock 9 includes a plurality of tumblers 10 on the side surface of a cylindrical main body, and when the key is inserted from the key hole 11 of the rotary handle 5, the tumbler 10 is retracted and can rotate with respect to the handle main body 3. However, the tumbler 10 protrudes when the key is pulled out after rotating to the locked position (for example, 90 degrees) and locked at that position. In this embodiment, a handle lock member 13 having an arm portion 12 is put on the head of the cylinder lock 9. If the handle lock member 13 is omitted, the tumbler 10 of the cylinder lock 9 may scrape the contact portion with the handle body 3. However, the handle lock member 13 is not an essential requirement of the present invention, and a cylinder lock 9 having an arm portion 12 may be used.

  As shown in FIG. 4, a rotation protrusion 14 is integrally provided on the back surface of the rotary handle 5. In this embodiment, the rotating protrusion 14 is provided in the vicinity of the outer periphery of the rotating handle 5, and the rotation of the rotating handle 5 is performed by positioning the arm 12 of the cylinder lock 9 on the rotation locus as shown in FIG. 6. Can be regulated. Further, when the cylinder lock 9 is rotated and the arm portion 12 is retracted from the rotation locus of the rotation projection 14 as shown in FIG. 5, the rotation operation of the rotary handle 5 becomes possible.

  In addition, a rotation angle restricting projection 19 is provided on the rear surface of the rotary handle 5 and is fitted in the arc groove 15 shown in FIG. This is for restricting the rotation angle of the rotary handle 5 to a predetermined angle (for example, 90 degrees).

  As shown in FIGS. 3 and 5, the handle main body 3 is formed with a contact portion 16 in which the arm portion 12 of the handle lock member 13 that covers the cylinder lock 9 is contacted. The handle body 3 is formed with a concave portion 18 for receiving the circular body portion 17 of the handle lock member 13. These abutting portions 16 and 18 sandwich the arm portion 12 of the cylinder lock 9 when viewed from the rotation projection 14 in the locked state where the cylinder lock 9 restricts the movement of the rotation projection 14 as shown in FIG. It is formed on the opposite side.

  In the handle device configured as described above, when the handle body 3 is turned to the position of OPEN shown in FIG. 5, the rotary plate 7 provided with the lock piece 6 rotates and the lock rods 8 and 8 move to move the door. 2 can be opened, and if the handle body 3 is turned to the CLOSE position shown in FIG. 6, the door 2 cannot be opened. Such a rotation operation of the handle body 3 can be freely performed when the cylinder lock 9 is in the position shown in FIG.

  However, when the handlebar body 3 is rotated to the CLOSE position shown in FIG. 6 and the cylinder lock 9 is set to the position shown in FIG. 6 and its arm 12 is positioned on the rotation locus of the rotating projection 14 of the handle body 3, the rotation is achieved. The handle 5 cannot be rotated, and the handle body 3 is locked.

  In the locked state of FIG. 6, even when the handle body 3 is rotated in the direction of OPEN with force, the circular body portion 17 of the cylinder lock 9 abuts against the abutment portion 18 of the handle body 3, and the cylinder lock Nine arm portions 12 abut on the abutment portion 16 of the handle body 3. For this reason, the rotational load applied to the cylinder lock 9 through the rotation protrusion 14 can be received by the contact portions 16 and 18, and the load is distributed as compared with the conventional structure in which the rotational load is received only by the tumbler 10 of the cylinder lock 9. Is done. For this reason, there is no possibility of damaging the handle device, and the lock can be locked more firmly.

  Further, in this embodiment, the load from the rotating projection 14 of the rotary handle 5 does not pass through the rotating shaft of the cylinder lock 9, and the load applied to the cylinder lock 9 is applied to the contact portions 16, 18 with the cylinder lock 9 from the lateral direction as a whole. It will take. Therefore, it is possible to lock more firmly.

  In the above embodiment, since the rotation protrusion 14 is provided near the outer periphery of the handle body 3, the movement distance of the rotation protrusion 14 is larger than when the rotation protrusion 14 is provided near the rotation shaft 4. Therefore, the load applied to the handle body 3 by the rotating projection 14 with respect to the same rotational torque is reduced, and there is no risk of damage even when the rotating projection 14 and the handle body 3 are made of resin. However, as shown in the following embodiment, the installation position of the rotation protrusion 14 is not limited to this example, and may be provided in the vicinity of the rotation shaft 4.

  7 to 9 show a second embodiment of the present invention. In the second embodiment, as shown in FIGS. 8 and 9, the rotation protrusion 20 is formed to protrude from the rotation shaft 4 of the rotation handle 5, but the arm portion 12 of the cylinder lock 9 is rotated around the rotation locus of the rotation protrusion 20. It is the same as in the first embodiment that the movement of the rotary handle 5 is restricted by being positioned above.

  In this embodiment, an abutting portion 18 is formed on the opposite side of the rotary protrusion 20 from the arm portion 12 of the cylinder lock 9 with the rotation shaft of the cylinder lock 9 interposed therebetween. For this reason, in the state of FIG. 9, the rotational load applied from the rotary protrusion 20 passes through the rotation shaft of the cylinder lock 9, but since the entire circular main body portion 17 of the cylinder lock 9 abuts against the abutment portion 18, the load is applied. Dispersed and strong lock is possible.

  If the rotation protrusion 20 is provided in the vicinity of the rotation shaft 4 of the rotary handle 5 as in the second embodiment, the width of the rotary handle can be reduced, which has the advantage that it can be applied to a vertically long handle.

  In the above-described embodiment, the circular rotary handle 5 is used, but a vertically long rotary handle can be used. Moreover, although the handle body 3 and the rotary handle 5 of the above-described embodiment are made of resin, they can be made of metal. In the embodiment described above, the handle body 3 is formed integrally with the door 2, but may be formed separately and incorporated in the door 2. Further, the arm portion may be directly projected from the cylinder lock 9 without covering the cylinder lock 9 with the handle lock member 13.

  For reference, FIG. 10 shows a structure in which the cylinder lock 9 is located away from the handle body 3 in the locked state. In other words, the rotational load of the rotary handle 5 is received only by the tumbler of the cylinder lock 9. In the case of this structure, since there are no contact portions 16 and 18 as in the present invention, the rotational load applied from the rotating projection 20 acts in the direction of rotating the arm portion 12 of the cylinder lock 9, and in the prior art section. As described, the connecting portion of the cylinder lock 9 and the rotary handle 5 may be damaged.

  As described above, according to the present invention, there is an advantage that the handle device is not damaged even when the cylinder lock is used as the locking device and the rotary handle 5 is rotated by force.
