The head of the blocking latch 12 screwed on the upper surface of the rear part of the handle shaft 51 is inserted into the through opening 332 and the elongated hole 333 above, which also limits the relative movement range of the handle 5 and the inner tube 3 in the axial direction (Fig. 6).

As shown in FIGS. 5 , 6 , and 13 , in the bearing cylinder portion 21 of the handle case 2 , a slit 212 extending forward and backward in the axial direction is formed facing the downward through opening 332 and the elongated hole 333 . When the fixed latch 71 protrudes from the through opening 332 toward the locked position ( FIG. 5 ), the lower end of the lower plate 722 of the actuating member 72 is exposed from the slit 212 toward the outer lower side of the bearing cylinder 21 .

As shown in Figures 7 and 9, the rotating body cam 73 is installed into the shaft of the handle in such a way that it can freely rotate around the shaft in the forward and reverse directions between the locked position (Figure 7) and the unlocked position (Figure 9). within 51. As shown in FIGS. 1 , 7 , 21 to 23 , the rotor cam 73 includes a shaft portion 732 , a flange portion 733 , a drive engagement portion 731 , and a protruding bar 734 . The cylindrical portion 732 is fitted to the rotating body 81 of the lock unit 8 with a slight gap in the rotating direction. The flange part 733 is formed on the front end of the shaft tube part 732 . The driving engaging portion 731 is protruded from the rear surface of the flange portion 733 . The protruding strip 734 is formed on the outer periphery of the shaft cylinder portion 732 so as to extend in the axial direction.

As shown in Figures 1, 5, and 7, the cylindrical portion 732 of the rotor cam 73 engages the protrusion 734 in the sector-shaped engaging recess 519, and is supported in the bearing hole of the handle shaft portion 51 in the rear end. 518. therefore, The rotating body cam 73 is integrated with the rotating body 81 of the lock head unit 8 within the angular range of the fan-shaped engagement recess 519, relative to the handle shaft between the locked position ( FIG. 7 ) and the unlocked position ( FIG. 9 ). The part 51 can freely rotate forward and reverse around an axis.

The rotating body 81 is an H-section shaft having two parallel flat surfaces 84 , and the bearing hole 735 of the shaft cylinder portion 732 fitted therein has a fan-shaped cross-section shape. A slight gap is formed in the direction of rotation between the rotating body 81 and the bearing hole 735 of the shaft cylinder portion 732 .

As shown in FIG. 23 , the driving engaging portion 731 has a driving contact surface 736 , a locking surface 737 , and a passive contact surface 738 .

The driving contact surface 736 is provided on the side of the rotating body cam 73 in the direction of rotation toward the unlocking side, and when the rotating body cam 73 rotates toward the unlocking position with the operation of the key, it abuts against the side of the fixed latch 71. The passive abutment surface 715 pushes the fixed latch 71 up to the unlocked position ( FIG. 9 ).

The locking surface 737 is in contact with the locking surface 716 of the fixed latch 71 when the rotating body cam 73 is in the locked position (FIG. 8), and the locking surface 716 of the fixed latch 71 is prevented from being fixed by the support and engagement of the two in the vertical direction. The latch 71 moves toward the unlocking direction (upward).

The passive abutment surface 738 is arranged on the surface on the opposite side of the rotation direction with the driving abutment surface 736, and when the activation member 72 is pushed up to the activation position by the activation rod 94, it is pushed by the drive slope 723 to make The rotating body cam 73 slightly rotates toward the non-locking direction, and the locking surface 737 is moved away from the mutually squeezed position perpendicular to the locking surface 716 of the fixed latch 71, allowing the fixed latch 71 to continue to go up. push.

As shown in FIGS. 1 and 5 , the lock unit 8 is installed into the handle 5 in such a way that a guard hood 14 is interposed between the lock box 82 and the fixing ring 13 . The lock box 82 has a cylindrical shape, has a screw portion 83 on the outer periphery, and has a pair of flat surfaces 84 parallel to the axis on opposite side portions. fixed The ring 13 has an annular groove 131 on its outer periphery, and is screwed and fixed on the outer periphery of the lock box 82 . The protective cover 14 is made of a hard material, which effectively resists violent damage by drilling machines and the like.

As shown in FIGS. 1 and 5 , the lock unit 8 is fixed in the handle shaft 51 by inserting the lock fixing member 11 into the handle shaft 51 through the fixing metal fitting insertion opening 517 in a direction perpendicular to the axis.

As shown in FIG. 2 , the electromagnetic coil 91 constituting the electric unlocking mechanism 9 together with the activation lever assembly 92 includes a pull plunger 912 protruding upward from a box-shaped electromagnetic coil case 911 .

The activation lever assembly 92 includes a bracket member 93 , an activation lever 94 , and a push-up member 95 .

The bracket member 93 is equipped with: a pair of parallel mounting plate parts 931, which are arranged along the left and right facing sides of the electromagnetic coil box 911; the bearing plate part 932 on the top of these mounting plate parts 931; Continue between the rear end edges of the mounting plate portion 931 and are arranged along the rear surface of the electromagnetic coil box 911 with an interval therebetween; The direction stands up. The bracket member 93 is fixed to the solenoid box 911 by screws 935 in the mounting plate portion 931 .

Therefore, the electromagnetic coil 91 and the activation rod assembly 92 constituting the electric unlocking mechanism 9 are formed as an integral unit through the bracket member 93 .

The activation rod 94 is pivotally supported to the bearing plate portion 932 by a horizontal pivot pin 941 in the middle portion, and pivotally connected to the plunger 912 by a horizontal pivot pin 942 in the front end side. The rear portion of the activation rod 94 is spring 943 toward the original position in the direction away from the lower end of the fixed latch 71 (downward), and the rear portion is raised by the pull-down of the plunger 912 to make the activation rod 94 Turn toward the lock release position. When the actuating lever 94 rotates toward the unlocking position, the fixed latch 71 at the locking position is pushed up to the unlocking position through the pushing-up member 95 .

The push-up member 95 is provided with a pivot portion 951, a push-up portion 952 above the pivot portion 951, and a sliding engagement portion 953 protruding downward, and is pivotally supported by a horizontal pivot pin 954 in the pivot portion 951 to activate Rear of rod 94. The sliding engagement portion 953 is engaged with the guide plate portion 933 of the bracket member 93 so as to be slidable in the vertical direction.

Therefore, when the push-up member 95 is rotated from the original position to the lock release position, the push-up member 95 makes the sliding engaging portion 953 slide vertically upward relative to the guide plate portion 933 , and pivots 954 relative to the starting lever 94 on the one hand. Rotate relative to the center, and push the push-up part 952 upwards substantially vertically.

When the fixed latch 71 is pushed up by the actuating rod 94 itself, since the actuating rod 94 will rotate and abut against the lower surface of the fixed latch 71, the upward thrust will become the vertical component of the input angle. Since the vertical force component is smaller than the attractive force of the electromagnetic coil 91 , in order to push up the fixed latch 71 , the excitation power of the electromagnetic coil 91 needs to be correspondingly increased. However, when the electric power available for the excitation of the electromagnetic coil 91 is limited, if only relying on the rotational force of the actuating lever 94, the upward thrust force for fixing the latch 71 may be insufficient. Therefore, the push-up member 95 is set in order to make up for the deficiency of the push-up force.

That is, when the actuating lever 94 rotates, since the fixed latch 71 is pushed up so that the push-up portion 952 protrudes substantially vertically upward, sufficient upward force can be obtained even if the attractive force of the electromagnetic coil 91 is relatively small. thrust.

A guard plate 15 made of hard metal is arranged in front of the electromagnetic coil 91 . The guard plate 15 prevents violent damage caused by a drilling machine attack on the electromagnetic coil 91 from the outside of the flange portion 22 of the handle case 2 .

The guard plate 15 is equipped with: a rectangular shielding plate portion 151, which shields the front of the electromagnetic coil 91; Standing up at right angles to the rear, and forming between each other to accommodate the front half of the electromagnetic coil box 911 The concave portion 153 and the fixing fin 154 protrude from the side plate portion 152 to the left and right in parallel with the shielding plate portion 151 . The guard plate 15 overlaps the fixed fin 154 and the fixed fin 934 of the bracket member 93, and is integrally fixed to the lower part of the flange part 22 of the handle box 2 with the common fixed bolt 16 with the starting lever assembly 92. surface side.

In addition, when the electric unlocking function is unnecessary, the handle device 1 with a lock without the electric unlocking mechanism 9 can be configured at a lower cost. In this kind of locking handle device 1, an electrical unlocking mechanism 9 may be installed as needed.

In the lockable handle device 1 that does not have the electric unlocking mechanism 9, it may happen that the lower part of the flange part 22 is broken with a drill from the front of the handle plate part 52, and the lower end part of the fixed latch 71 is pushed up from the outside. violent theft. In order to prevent such brute force theft, the guard plate 15 is separately attached to the lower rear surface side of the flange portion 22 even when the electric unlocking mechanism 9 is not installed.

It is hereby explained that from the state shown in Fig. 5 in which the door D is locked in the locked state by the lock member 4, the lock of the door D is unlocked, the door D is opened and the operation is completed, and then the lock is locked again and the lock is performed. the process of.

In the state shown in Fig. 5, Fig. 7 and Fig. 8, the locking member 4 is located at the locked position, the handle 5 is submerged in the handle box 2, and the fixed latch 71 is located at the through opening engaged with the inner cylinder 3 332, and the rotating body 81 and the rotating body cam 73 of the locking unit 8 are also in the locking position.

From this state, when the key is inserted into the lock head unit 8 and rotated clockwise in FIG. 8 so that the rotating body 81 comes to the unlocked position, the driving engaging portion 731 of the rotating body cam 73 pushes the locking lock on one side. The passive abutting surface 715 of the latch 71 pulls the fixed latch 71 into the unlocked position. When the fixed latch 71 disengages from the through opening 332 of the inner tube 3 ( FIG. 9 ), the handle 5 will be pushed out from the handle box 2 by the spring member 6 ( FIG. 6 ). In this state, the fixed latch 71 is locked by the peripheral wall 33 of the inner cylinder 3. remain in the unlocked position. On the other hand, the rotating body 81 and the rotating body cam 73 are returned to the locked position by the elastic thrust of the spring 10 .

Thereby, when the handle 5 is grasped, for example, when the handle 5 is rotated 90 degrees counterclockwise, the locking member 4 rotates together with the inner tube 3 toward the unlocked position, and then disengages from the corresponding engaging part of the casing not shown in the figure. Therefore, door D can be opened.

After completing the required work, close the door D, and rotate the handle 5, together with the inner tube 3 and the locking member 4, 90 degrees clockwise to return to the locked position, and push the handle 5 into the handle box 2. When the handle 5 is pushed into the handle box 2, the fixed latch 71 is at a position opposite to the through opening 332 of the inner cylinder 3, and is pushed by the spring 717 to automatically protrude from the handle shaft 51 and meet the through opening. 332 is engaged, and the handle 5 is restrained, so the door D is locked on the casing. The lockable handle device 1 is tied back to the locked state in FIGS. 7 and 8 , and the key can be pulled out from the lock head unit 8 .

In addition, the lockable handle device 1 can be unlocked as long as the electrical unlocking mechanism 9 is activated by an electrical signal from a remote end without relying on the operation of the lock head unit 8 by a key.

In the locked position of FIG. 5 , the activation member 72 is located in the lower non-activation position, and the activation lever 94 is inclined backward and downward, and the upper surface of the push-up member 95 is substantially horizontally connected with the lower surface of the activation member 72 . When the electromagnetic coil 91 is energized from this state, as shown in FIG. 6 , the plunger 912 retreats downward, and the activation lever 94 rotates counterclockwise around the pivot pin 941, and the push-up member 95 is approximately vertically upward. Push up.

The push-up member 95 first abuts against the lower surface of the activation member 72 and pushes the activation member 72 up to the upper activation position ( FIG. 10 a ). When the activation member 72 rises, the rotor cam 73 will be pushed by the driving slope 723 of the activation member 72 to slightly rotate toward the unlocking direction (clockwise in FIG. 10 a ). By the initial rotation of the rotor cam 73, in FIG. 8 in the vertical direction with the fixed The locking surface 716 of the latch 71 is used as the locking surface 737 for supporting and engaging, and the locking surface 737 is disengaged from the locking surface 716, so as to untie the restraint in the vertical direction of the fixing latch 71 . The actuating lever 94 is further rotated and the push-up member 95 pushes the fixed latch 71 integrally with the actuating member 72 to the unlocked position (Fig. 10b). Thereby, the lock part 712 of the fixed latch 71 is disengaged from the through opening 332, and the handle 5 protrudes from the handle case 2 (FIG. 6).

In the locked position, the fixed latch 71 is spring 717 springs toward the downward locked position, and is prevented from moving upward in the unlocked direction by the locked surface 737 of the rotating body cam 73 ( FIG. 8 ). Therefore, in order to push up the fixed latch 71 from the outside, in addition to rotating the rotor cam 73 against the spring 10 in the unlocking direction, a force to compress the spring 717 is also required. Therefore, even if the fixed latch 71 receives an upward force due to violent vibration or impact from the outside, it will not rise in the unlocking direction, and high defense performance against theft can be exhibited.
