The lock device 100 is provided with a handle 110 on the front surface facing the front side of the opening and closing side frame 24, and is used to block the door sash when the handle 110 is operated to the locked position in a state where the opening 10a of the opening frame 10 is closed. 20 relative to the mover of the open frame 10. The lock devices 100 provided in the respective door sashes 20 have a symmetrical configuration with each other, so only the lock between the door sash 20 on the right side and the open frame 10 in Fig. 1 will be described below. The device 100 will be described.

As shown in Fig. 3 (a) and (b), the handle 110 is formed in a lever shape arranged in the vertical direction, and is transmitted through the handle shaft 111 provided in the lower end portion thereof in the horizontal direction. Rotatingly supported by the lower end of the handle base 112, as shown in FIG. 3(a), when placed along the opening and closing side frame 24, it becomes a locked position, and is accommodated in the handle base. 112. In this state, the engaging member 113 provided on the handle base 112 is engaged with the upper end of the handle 110, and the handle 110 is maintained in the state of being accommodated in the handle base 112. When the engaging member 113 is pressed from this state, the engagement state with the handle 110 is released, and the upper end portion of the handle 110 can be pulled out to the front side to operate to the unlocking position shown in FIG. 3(b). .

In the handle base 112, a slide base 114 is provided. The sliding base 114 is attached to the opening and closing side frame when the handle 110 is operated The long side of the 24 moves. Specifically, as shown in FIG. 3( a ), when the handle 110 is operated to the locked position, the slide base 114 is moved upward relative to the handle base 112, and as shown in FIG. 3( b ), When the handle 110 is operated to the unlocked position, the slide base 114 is configured to move downward with respect to the handle base 112. As shown in FIGS. 2 and 4, a slider 115 provided on the depth surface of the opening and closing side frame 24 is coupled to the slide base 114. The slider 115 extends along the longitudinal direction of the opening and closing side frame 24, and has a hook member (locking member) 120, a stopper member 130, and an actuation groove 115a.

As shown in FIGS. 2, 4, and 5, the hook member 120 is a plate-like member that is bent at a substantially right angle toward the upper side after the slider 115 protrudes substantially horizontally from the longitudinal surface of the vertical frame 13. The amount by which the hook member 120 protrudes from the slider 115 is set such that the gap between the front end portion of the hook member 120 and the longitudinal surface of the vertical frame 13 can be ensured even when the door sash 20 is slid to close the opening 10a of the opening frame 10. . The hook member 120 is fixed to the slider 115 at a portion above the slide base 114.

As shown in FIGS. 4 and 6, the stopper member 130 is formed in a block shape having substantially the same width as the slider 115. The stopper member 130 is fixed to the slider 115 in a state protruding from a portion of the slider 115 between the hook member 120 and the slide base 114 toward the longitudinal surface of the vertical frame 13. The amount by which the stopper member 130 protrudes from the slider 115 is substantially the same as the amount by which the hook member 120 protrudes from the slider 115.

As shown in FIG. 4, FIG. 7, FIG. 8, and FIG. 11, the touch groove 115a is a groove-shaped notch formed in a portion of the slider 115 that is lower than the slide base 114, and is slid along the slide. The shape of the long side of the block 115 is shaped to make. In the touch groove 115a, a touch piece 140 is disposed. The touch piece 140 is formed in a rectangular parallelepiped shape that can be inserted into the contact groove 115a of the slider 115, and is disposed to be movable in a direction approaching and away from the longitudinal surface of the vertical frame 13. As can be seen from the figure, in the touch piece 140, a projection 141 is provided at a portion facing the longitudinal surface of the vertical frame 13. The protrusion 141 has a protruding length larger than the plate thickness of the slider 115, and protrudes from the upper end portion of the touch piece 140 in a substantially horizontal manner. Although not shown in the drawings, between the touch piece 140 and the handle base 112, a contact spring that elastically pushes the touch piece 140 in the protruding direction is provided.

As shown in FIG. 4, in a state where the touch piece 140 is disposed in the touch groove 115a of the slider 115, since the touch piece 140 abuts against both end edges of the touch groove 115a, the slider 115 cannot be made relative to the handle base. 112 moves. On the other hand, when the transmitting projection 141 moves the biasing piece 140 against the spring force of the biasing spring, only the projection 141 is disposed in the actuation groove 115a of the slider 115. Therefore, in this state, the slider 115 can be moved relative to the handle base 112 in a range in which the projection 141 abuts against both end edges of the actuation groove 115a.

On the other hand, in the portion of the vertical surface of the vertical frame 13 that faces the opening and closing side frame 24, the contact seat member 150, the hook seat member 160, and the stopper seat member 170 are disposed.

The touch block member 150 is formed in a rectangular parallelepiped shape and is attached to a portion opposed to the touch piece 140. When the door sash 20 is slid to close the opening 10a of the opening frame 10, as shown in FIG. 7, the contact seat member 150 resists the spring force of the spring by abutting against the protrusion 141. The touch piece 140 is retracted, and the touch piece 140 is disengaged from the actuation groove 115a of the slider 115.

As shown in FIG. 4, the hook member 160 has an opening at a portion facing the longitudinal surface of the vertical frame 13, and is formed into a hollow rectangular parallelepiped having a length three times longer than the front end portion of the hook member 120, and The vertical frame 13 is fixed to the vertical frame 13 by a flange 161 in a state where the vertical direction is the long side. In the hook member 160, an insertion hole 162 is provided on a surface facing the opening and closing side frame 24 of the door sash 20. The insertion hole 162 is an opening that can be inserted into the front end portion of the hook member 120, and is formed at a substantially central portion in the vertical direction. The hook member 160 is mounted such that when the door sash 20 is slid to close the opening 10a of the opening frame 10 in a state where the handle 110 is in the unlocked position, as shown in FIG. 7, the front end portion of the hook member 120 can be inserted. When the through hole 162 is passed, and when the handle 110 is directly operated to the locked position, as shown in FIGS. 8 and 9, the front end portion of the hook member 120 is overlapped with the wall portion higher than the insertion hole 162. height.

The stopper seat member 170 is formed in a substantially rectangular parallelepiped shape, and is configured to have a long side in the vertical direction and a pair of upper and lower sliding grooves 171. The sliding groove 171 is a notch having a small width extending in the vertical direction, and is formed to have a length greater than a moving length of the sliding base 114 formed by the operation of the handle 110. The mounting screw 172 is screwed to the longitudinal surface of the vertical frame 13 through the sliding groove 171, whereby the stopper member 170 can be slid along the sliding groove 171, and in the normal state, the mounting screw is used by its own weight. 172 is disposed in a state of being disposed at an upper end of the sliding groove 171, that is, a state in which it is positioned at a lowermost position (abutting position) with respect to the vertical frame 13 In the vertical frame 13.

As can also be seen from the figure, the stopper member 170 is configured to protrude from the longitudinal surface of the vertical frame 13 by a larger amount than the hook member 160. Further, as shown in FIGS. 4 and 7, the lower end surface 170a of the stopper member 170 located at the lowermost position with respect to the vertical frame 13 is disposed to be located at the stopper member 130 when the handle 110 is in the unlocked position. When the upper end surface 130a is further above and the door sash 20 is slid to close the opening 10a of the opening frame 10, it faces the upper end surface 130a of the stopper member 130. When the handle 110 is operated to the locked position, as shown in FIG. 11, the upper end surface 130a of the stopper member 130 is set above the lower end surface 170a of the stopper seat member 170.

In the door and window having the lock device 100 configured as described above, as shown in FIG. 4, when the opening 10a of the opening frame 10 is in the open state, the upper end surface 130a of the stopper member 130 is operated as long as the handle 110 is operated to the unlocked position. It is disposed below the lower end surface 170a of the stopper member 170. Therefore, when the door sash 20 is slid and the opening 10a of the opening frame 10 is closed, as shown in FIG. 7, the front end portion of the hook member 120 is inserted into the insertion hole 162 of the hook member 160. At this time, since the protrusion 141 of the touch piece 140 abuts against the contact seat member 150, the touch piece 140 is in a state of being separated from the actuation groove 115a of the slider 115. Therefore, as long as the handle 110 is operated to the locked position from this state, as shown in Fig. 8, the slide base 114 is moved upward with respect to the handle base 112, and soon the upper end surface 130a of the stopper member 130 is abutted. It is connected to the lower end surface 170a of the stopper member 170. As shown in FIGS. 8 and 10, the upper end surface 130a of the stopper member 130 abuts against the lower end surface 170a of the stopper member 170. Thereafter, since the stopper member 170 is moved upward relative to the vertical frame 13 by the stopper member 130, the hook member 120 is engaged with the hook member 160 to prevent the door sash 20 from sliding relative to the opening frame 10. status.
