The lower end of one of the rotating ends can be rotated by pushing the actuating lever 13. More specifically, the lock lever 14 is formed of a vertically long rectangular flat plate-shaped pressed portion 141 that can be disposed in the opening portion 110 of the main body casing 11; a side portion from the pressed portion 141 a convex pressing portion 142 which is bent in a direction of about 90 degrees and protrudes; and an upper portion and a lower portion which are formed at a transition portion between the pressed portion 141 and the pressing portion 142 which are sandwiched at an angle of about 90 degrees, and are provided One of the through holes through which the shaft 140 is inserted in the vertical direction is formed by the shaft insertion portions 143 and 143, and is formed in a substantially L-shaped cross-sectional shape as a whole. Such a lock lever 14 is formed so as to be reversed in the left-right direction, and can be selectively attached to either one of the right and left side portions of the rocker 32. The shaft 140 is inserted into the through hole of the upper and lower shaft insertion portions 143 and 143, and the shaft 140 is attached to the shaft for the shaft of the shaft and pin holder 113 of the embedded portion 111 of the body casing 11, and the shaft and the slide rod Between the holes for the shaft of the holder 115. Thereby, the lock lever 14 is mounted such that the pressed portion 141 faces a predetermined position in the opening portion 110, and the pressing portion 142 is bent into the outer side of one side surface of the body casing 11 toward a predetermined position, and is rotatable around the shaft 140. Turn. Further, by the biasing of the coil spring 144 wound around the shaft 140 in advance, the pressed portion 141 of the lock lever 14 is normally rotated toward a predetermined position in the opening portion 110.

The stopper 15 is provided to the main body casing 11 so as to be engageable and disengageable with the rotating end of the handle 12, as shown in Fig. 6, and the handle 12 is held in the falling position in a normal state by a spring means. The stopper 15 is formed in a substantially rectangular plate shape that can be fitted into the opening portion 110 at a lower portion of the covering portion 112 of the body casing 11, and a lower end thereof is formed in a projecting shape that slightly protrudes into the opening portion 110. Further, a pair of arm portions 151, 151 are formed to protrude from the back surface of the stopper 15, and shaft insertion holes 152, 152 are formed through the perforations at the protruding ends of the respective arm portions. Such a stopper 15 is formed to be bilaterally symmetrical and selectively attachable to either one of the right and left side portions of the rocker 32. The pair of arm portions 151, 151 are fitted into the opening portion 110 at the lower portion of the covering portion 112 of the body casing 11, and the shaft 150 is inserted into the shaft insertion holes 117, 117 provided on both side faces of the embedded portion 111 and the shaft insertion of the stopper 15. Through holes 152, 152. A coil spring (not shown) is wound around the shaft 150, and one end of the coil spring is snapped under the configuration portion 114 of the intermediate portion of the body casing 11, and the other end is snapped on the back surface of the stopper 15. Lower part. In this case, the coil spring on the side of the stopper 15 is a spring that is stronger than the coil spring on the side of the handle 12 . In this manner, the stopper 15 is attached so as to be pivotally supported to be slightly rotated into the lower portion of the opening portion 110 of the body casing 11, and the lower end portion abuts against the rim of the opening portion 110 without It is detached and can be engaged and disengaged from the rotating end of the handle 12. By pushing the handle 12 from the pulled-up position protruding from the body casing 11 back to the lodging position in the opening portion 110 of the body casing 11, the rotating end of the handle 12, that is, the guiding portion 123 at the lower end of the handle 12 is abutted. At the upper end portion of the stopper 15, the stopper 15 is rotationally displaced downward. When the lower end of the handle 12 spans the upper end portion of the stopper 15, the stopper 15 is elastically returned to the original position, and the upper end portion thereof is engaged with the fastening portion 122 of the lower end of the handle 12. Since the elastic force of the coil spring on the side of the stopper 15 is stronger than the elastic force of the coil spring on the side of the handle 12, the handle 12 can be held in the lodging position in the body casing 11. In this state, the lower portion of the front surface of the stopper 15 is pressed, and the stopper 15 is rotationally displaced downward so that the engagement of the upper end portion with the fastening portion 122 of the lower end of the handle 12 is released, and the handle 12 is rotated to the main body. The lodging position in the casing 11 protrudes to the pulled up position.

A lock unit 154 is attached to a cylindrical hole 119 provided below the stopper 15, that is, at a lower portion of the body casing 11. The lock unit 154 has a rotor 155 that can be rotated by a predetermined key, and a rotor cam 156 that is fixed at a right angle to the axial direction of the rotor 155 at the rear end of the rotor 155 so as to be rotatable integrally with the rotor 155, the rotor cam The 156 is disposed in the lower portion of the opening 110 of the main body casing 11 through the slot 119P located at the rear end portion of the hole 119. Therefore, the rotor 155 is rotated in a predetermined direction by a predetermined key, and the rotor cam 156 is projected to a locked position that restricts the action (rotation) of the stopper 15, and the handle 12 is locked in the lodging position. By rotating the rotor 155 in the opposite direction, the rotor cam 156 is reversed to the unlocked position that allows the action (rotation) of the stopper 15 to release the lock that holds the handle 12 in the collapsed position.

The cam member 16 is pivotally supported in the body casing 11 by the shaft 121 of the handle 12 and extends to the back side of the rocker 32 as shown in Fig. 6, and is mounted to be inside the opening 110 and the handle 12 is integrally rotated between the back side and the front side of the rocker 32. The entire shape of the cam member 16 including the actuating lever 13 is formed into a substantially quadrangular shape, and one angle projects upward from the upper side of the actuating lever 13 (the upper end portion of the connecting handle 12 and the edge of the projecting end of the actuating lever 13). On both side faces of the cam member 16, a common hole is formed at a position corresponding to each of the mounting holes 135, 135, 135 of the actuating lever 13, and a pin insertion hole 161 is formed at a corner protruding above the actuating lever 13. The cam member 16 is formed to be bilaterally symmetrical and selectively attachable to either one of the right and left side portions of the rocker 32. The cam member 16 is fixed to the side surface of one side of the actuating lever 13 by the mounting holes 135, 135, 135 (the mounting holes of the cam member 16, not shown) that are locked to the actuating lever 13 by the mounting screws, and is pivoted with The handles 12 are supported together in the opening portion 110 of the body casing 11. The slider 17 is formed of an elongated plate having a predetermined length as shown in Fig. 6, and the intermediate portion is formed to be slightly wider. At the upper end portion of the slide bar 17, a mounting hole 171 for coupling to the lock lever 25 of the multi-point lock type lock device 2 is formed, and an elongated hole 172 which is long in the width direction of the slide bar 17 is formed at the intermediate portion. . The slide bars 17 are formed to be bilaterally symmetrical and selectively attachable to either one of the right and left side portions of the rocker 32. Inserting the slide bar 17 through the insertion hole 116 of the slide bar provided at the upper portion of the embedded portion 111, and the hole for the slide bar of the shaft cum slider support 115 provided at the intermediate portion of the embedded portion 111, and then A pin 173 protruding from the side of the shaft and pin holder 113 is inserted through the long hole 172 of the intermediate portion and the pin insertion hole 161 at the upper portion of the cam member 16. Thereby, the slide bar 17 is attached so as to be pivotally supported by the cam member 16, and the rotation of the cam member 16 is converted into a linear motion, and can be linearly advanced and retracted toward the vertical direction of the body casing 11.

The lock lever 1 for a sill as described above is attached to the side portion 321 on the rotation side of the rocker 32 through the main body casing 11 as shown in Fig. 9. The handle 12 is supported in a pivotable manner by a shaft 121 parallel to the front surface of the sill 32, and is rotatable between a predetermined lodging position and a predetermined pulled-up position in a plane at right angles to the surface, and The stopper 15 is held in the lodging position by the buckle end. The actuating lever 13 extends to the back side of the handle 12 and is pivotally supported to be rotatable integrally with the handle 12 between the back side and the front side of the rocker 32 (see Fig. 6). The lock lever 14 is pivotally supported by a shaft 140 having a right angle with respect to the shaft 121 on the back side of the rocker 32, and is configured such that one of the rotational ends faces the actuating lever 13 and the other rotational end faces the frame side. The buckle portion 312 is rotatable. By rotating the handle 12 toward the lodging position, the actuating lever 13 is rotated from the front side of the rocker 32 to the back side, and one of the rotational ends of the lock lever 14 is pushed to rotate the lock lever 14 as a whole, and the other can be rotated. The end is crimped to the buckle portion 312 on the side of the frame.

As described above, the sill lock 1 is attached to the sill 32, and the handle 12 is rotated in a state where the sill 32 is closed with respect to the frame 31, and the lock lever 14 is rotated to be formed on the frame 31. The buckle portion 312 of the front opening edge is detached or fastened to open or close the sill 32. In this case, in a state where the sill 32 is open, as shown in Fig. 10(a), the handle 12 is detached from the stopper 15, and the rotation of the lock lever 14 by the spring force of the coil spring 144 causes the rotation of the lock lever 14 by the spring force of the coil spring 144. The pressed portion 141 is rotationally displaced toward the inside of the body casing 11, and the actuating lever 13 is rotationally displaced from the back side of the rocker 32 toward the front side. At the same time, the handle 12 integrated with the actuating lever 13 is rotationally displaced from the lodging position in the body casing 11 toward the pulled-up position, and the spring pressure of the coil spring on the shaft 121 of the handle 12 is used to fully rotate the handle 12. To the pull up position. That is, the handle 12 is in a state of protruding from the front surface of the sill 32. From this state, the sill 32 is closed, and the handle 12 is rotated toward the body casing 11 to the lodging position, as shown in Fig. 10(b), whereby the actuating lever 13 integral with the handle 12 is oriented from the front side of the sill 32. The back side is rotated. The actuating lever 13 presses the pressed portion 141 of the lock lever 14 to rotate the pressing portion 142 toward the buckle portion 312 on the frame side. Then, the handle 12 is pressed into the lodging position in the opening portion 110 of the body casing 11, and the actuating lever 13 presses the lock lever 14 (the pressed portion 141) to the bottom, so that the pressing portion 142 is strong from the back side toward the front side. The ground is crimped to the buckle portion 312 on the side of the frame. By the crimping, the sill 32 is strongly pulled against the frame 31 side, and the washer 313 which completely compresses the opening edge of the frame 31 is completely sealed. During this time, the rotating end of the handle 12, that is, the guiding portion 123 of the lower end of the handle 12, abuts against the upper end portion of the stopper 15 to be rotationally displaced downward, and then passes over the lower end of the handle 12 to stop. The upper end portion of the device 15 and the stopper 15 are elastically returned to the original position, and the fastening portion 122 at the lower end of the handle 12 is engaged with the upper end portion of the stopper 15. Since the elastic force of the coil spring on the side of the stopper 15 is stronger than the elastic force of the coil spring on the side of the handle 12, the handle 12 is fixed to the lodging position in the body casing 11. Thereby, the sill 32 is tightly closed to the front surface of the casing 31, and the opening portion 310 of the casing 31 is kept in a completely sealed state. In this case, the lock unit 154 under the stopper 15 is inserted into a predetermined key, and then the rotor 155 is rotated to bring the rotor cam 156 to the lock position, thereby restricting the action of the stopper 15, pulling the handle 12 upward. The rotation locks to lock the sill 32. From this state, a predetermined key is inserted in the lock unit 154, and the rotor 155 is rotated in the opposite direction to cause the rotor cam 156 to reach the unlocked position, thereby allowing the stopper 15 to operate. At this time, the lower portion of the front surface of the stopper 15 is pressed, and the stopper 15 is rotationally displaced downward, and the fastening portion of the lower end portion of the handle 12 is released from the upper end portion of the stopper 15, and the locking of the handle 12 is released. . By the rotation of the lock lever 14 by the bias of the coil spring 144, the pressed portion 141 is rotated toward the inside of the body casing 11, and the actuating lever 13 is urged to rotate from the back side of the rocker 32 toward the front side. The handle 12 integrated with the actuating lever 13 is rotated (rotated) from the lodging position toward the pulled-up position, and the handle 12 is fully rotated to the pulled-up position by the elastic pressure of the coil spring on the shaft 121 of the handle 12. That is, the state in which the handle 12 protrudes from the front surface of the sill 32 is released, and the locked state of the sill 32 is released.

Further, the multi-point lock type lock device 2 using the lock for the sill is connected to each of the terminal lock members 21 disposed above and below the side portion on the side of the rotation side of the back surface of the sill 32 as shown in Fig. 4; The lock lever 25 is interlocked with the operation of the handle 12 attached to the front surface of the sill 32, and is guided forward and backward along the side of the rotation side of the back surface of the sill 32 under the guidance of the lock lever guide 26, so that the respective terminal lock members The terminal locking lever 24 of the 21 is engaged or disengaged from the buckle portion 312 on the frame side. In this case, in a state where the sill 32 is open, the handle 12 is detached from the stopper 15, and the pressed portion 14 is directed toward the body casing 11 by the rotation of the lock lever 14 by the bias of the coil spring 144. The displacement is rotated, and the actuating lever 13 is pushed to be rotationally displaced from the back side of the rocker 32 toward the front side. The cam member 16 integrated with the actuating lever 13 is also rotationally displaced from the back side of the rocker 32 toward the front side, whereby the slide bar 17 is displaced downward along the side of the rotation side of the back surface of the rocker 32. The lock lever 25 coupled to the slide bar 17 is interlocked, and is guided downward along the side of the back surface of the rocker 32 under the guidance of the lock lever guide 26, as shown in Fig. 3(a). In the sliding space of the terminal casings 22, 22, a state in which each of the terminal sliders 23 is slidably displaced downward is formed. At this time, the terminal locking lever 24 is not pressed against the guide surface 232 of the terminal slider 23. Therefore, the terminal locking lever 24 is rotated by the biasing force of the coil spring 244, and the pressing portion 241 is rotationally displaced to a predetermined position in the opening portion 226 of the cartridge body 225, and the pressing portion 242 is buckled from the frame side. The state of the part 312 is detached.

From this state, the handle 12 is rotated toward the main body casing 11 to the lodging position, so that the actuating lever 13 integral with the handle 12 is rotated from the front side toward the rear side of the rocker 32, and the cam member integrated with the actuating lever 13 is formed. 16 also rotates from the front side to the front side of the sill 32. Then, by the rotation of the cam member 16, the slide bar 17 is displaced upward, and the lock lever 25 coupled to the slide bar 17 is interlocked, and is moved upward by the lock lever guide 26. By moving the lock lever 25 upward, the terminal sliders 23 are slid upward in the sliding space of each of the upper and lower terminal casings 22, and as shown in FIG. 3(b), the terminal locking levers are provided. The pressed portion 241 of the pressing portion 241 of 24 is pressed against the guide surface 232 to be guided by the guide surface 232, and is pressed and pressed, whereby the pressing portion 242 is rotated toward the buckle portion 312 on the frame side. Then, the handle 12 is pressed into the falling position in the opening portion 110 to press the terminal locking levers 24 (the pressed portions 241) of the terminal casing 22 to the bottom through the cam member 16, the slide bar 17, and the lock lever 25. The pressing portion 242 is strongly pressed against the buckle portion 312 on the frame side from the back side toward the front side. By the crimping, the sill 32 is strongly pulled against the frame 31 side, and the washer 313 which completely compresses the opening edge of the frame 31 is completely sealed. During this time, the rotating end of the handle 12, that is, the guiding portion 123 of the lower end of the handle 12, abuts against the upper end portion of the stopper 15 to be rotationally displaced downward, and then passes over the lower end of the handle 12 to stop. The upper end portion of the device 15 and the stopper 15 are elastically returned to the original position, and the fastening portion 122 at the lower end of the handle 12 is engaged with the upper end portion of the stopper 15. Since the elastic force of the coil spring on the side of the stopper 15 is stronger than the elastic force of the coil spring on the side of the handle 12, the handle 12 is fixed to the lodging position in the body casing 11. Thereby, the sill 32 is tightly closed to the front surface of the casing 31, and the opening 310 of the casing 31 is kept in a completely sealed state. In this state, when the lower portion of the front surface of the stopper 15 is pressed, the stopper 15 is rotationally displaced downward, and the fastening portion of the lower end portion of the handle 12 and the upper end portion of the stopper 15 are released. By the rotation of the lock lever 14 by the biasing of the coil spring 144, the pressed portion 141 is rotated toward the inside of the body casing 11, and the cam member 16 is rotated from the back side of the rocker 32 toward the front side. By the rotation of the cam member 16, the slide bar 17 is slid downward, and the lock lever 25 coupled to the slide bar 17 is interlocked, and is moved downward by the lock lever guide 26. By the downward movement of the lock lever 25, the terminal sliders 23 are slid downward in the sliding space of each of the upper and lower terminal casings 22 to release the engagement between the guide surface 232 and the terminal lock lever 24. Therefore, the terminal locking lever 24 is rotationally displaced by the biasing of the coil spring 244 to a predetermined position in the opening 226 of the terminal casing 22, so that the pressing portion 242 is biased from the casing portion 312 of the casing side. Get rid of. That is, the locked state of the threshold 32 is released.

As described above, the multi-point lock type lock device 2 is a type in which a terminal lock member 21 having a plurality of portions disposed on the side of the side of the swing side on the back side of the rocker 32 is attached to the sill 32. The front door is interlocked with the operation of the handle of the lock lever, and the lock lever 25 coupled to each of the terminal lock members 21 is moved forward and backward along the side of the back surface of the rocker 32, whereby the terminal lock lever of each of the terminal lock members 21 is caused. 24 is engaged and disengaged from the buckle portion 312 on the frame side.

The actuating lever 13 is pivotally supported on the same shaft as the handle 12 and extends to the back side of the rocker 32, and is integral with the handle 12 in the opening portion 110 on the back side and the front side of the rocker 32. Rotate between. The lock lever 14 has a substantially L-shaped cross-sectional shape, and is pivotally mounted on a side portion of the body case 11 disposed on the back side of the rocker 32 by a shaft 140 at right angles to the shaft 121 of the handle 12. Supports the approximate middle portion of the cross-sectional shape. The lock lever 14 is such that one of its L-shaped rotational ends faces the actuating lever 13, and the other rotational end faces the frame-side retaining portion 312, and is mounted in a rotatable manner, and is biased by the spring force of the spring means 144. Normally, one of the rotating ends can be rotated by pushing the actuating lever 13. The stopper 15 is disposed on the body casing 11 in such a manner as to be engageable and disengageable from the rotating end of the handle 12 for holding the handle 12 in the lodging position, and the spring means (coil spring) has the biasing handle 12 to pull it up The function of the brake that is rotated to maintain the position. The cam member 16 is pivotally supported by the body casing 11 by the shaft 121 of the handle 12 and extends to the back side of the rocker 32, and is integral with the handle 12 in the opening portion 110 on the back side of the rocker 32. Rotate between the front sides. The slide bar 17 is pivotally supported by the cam member 16, converts the rotation of the cam member 16 into a linear motion, and can linearly advance and retreat along the side of the rotation side of the back surface of the rocker 32.

Each of the terminal lock members 21 is provided with a terminal body 22 that is provided on the side of the back side of the sill 32 on the side of the rotation, and that is provided with both ends facing the extending direction (up-and-down direction) of the side portion; slidably disposed at a terminal slider 23 in the terminal casing 22; and a rotatably mounted to the terminal casing 22, by which the terminal slider 23 is engaged and retracted, one of the rotating ends is fastened to the terminal slider 23 and guided by the terminal slider 23 The rotating end of one of the ends can be engaged with or disengaged from the buckle portion 312 of the frame side.
