Japanese Patent Laid-Open No. 2000-204821

  However, in the case of the above-mentioned conventional patent document 1 disclosed in the above-mentioned Patent Document 1, the sliding rail on the side surface of the left frame of the window frame is used to hold the shoji in the intermediate opening state where it falls to a predetermined angle. It is necessary to provide a slide mechanism consisting of the above and a latch mechanism which does not extend the first and second arms on the side of the port side of the shoji. For this reason, in the above-mentioned conventional apparatus for holding the inward-opening window in the open state, many parts constituting each mechanism are required on both the window frame side and the side of the window, and the product cost of the falling window increases. Moreover, it is necessary to secure the space which comprises each mechanism in both the window frame side and the shoji side, and thickness reduction of the frame which comprises a fall window becomes difficult.

The present invention has been made to solve such problems.
In a fall window locking mechanism of a falling window, which is supported by an arm that connects the window frame and the shoji, and holds in a state in which the window is folded at a predetermined angle,
It is attached to the opposite face opposite to the vertical frame of the window frame in the vertical frame of the shoji, or on the opposite surface opposite to the vertical ridge of the shoji in the vertical frame of the window frame, along the longitudinal direction of the vertical frame of the vertical frame or window frame A slide rail having a track and a slide surface extending in a vertical direction, and a hole opened at a predetermined position on the slide surface according to the falling angle of the shoji
A slide member movably attached to the slide rail along the track, swingably supporting one end of the arm, and moving the track in one direction by swinging the one end of the arm when the shoji is opened ,
A lock member which is movable in one direction along the track together with the slide member with the other end at the top by being rotatably attached to the slide member at one end,
Provided between the slide member and the lock member, the other end of the lock member is biased toward the slide surface, and when the slide member moves in one direction, the other end of the lock member is brought into sliding contact with the slide surface to engage with the hole A first elastic member to be engaged;
The lock release position, which is attached to the slide rail so as to be movable along the slide surface, and the tip located at the front reaches the hole when moving in one direction and pushes up the other end of the lock member engaged with the hole; An unlocking member which moves along the sliding surface between the retreating position where the contact does not reach the hole,
And a second elastic member for urging the lock release member along the slide surface to the retracted position.

  According to this configuration, when the shoji is opened, the one end of the arm swings, and the slide member that swingably supports the one end of the arm moves the track of the slide rail in one direction. At this time, the lock member, one end of which is rotatably attached to the slide member, is urged toward the slide surface of the slide rail by the first elastic member at the other end, and slides on the slide surface. When the shoji falls down to a predetermined angle, the other end of the lock member is fitted into the hole opened in the slide surface and engaged with this hole. Therefore, the movement of the slide member in one direction is blocked, and the arm whose one end is supported by the slide member is held at the position where the movement of the slide member is blocked, and the shoji supported by the arm falls at a predetermined angle It is held in the state.

  The unlocking member is always urged by the second elastic member, and held at the retracted position where the leading end located at the beginning does not reach the hole when moving in one direction. When the unlocking member is moved in one direction along the slide surface against the biasing force of the second elastic member with the shoji folded down to a predetermined angle, the tip of the unlocking member reaches the hole, The other end of the locking member is pushed up from the hole. Accordingly, the engagement with the hole at the other end of the locking member is released, and the slide member moves in one direction in the track of the slide rail in one direction, but the movement is restricted at the end of the track of the slide rail and stops. Therefore, the arm whose one end is supported by the slide member is held at the position at which the slide member is stopped, and the shoji supported by the arm is held in the most fallen state. In this state, when the collapsed shoji is raised, one end of the arm swings in the reverse direction, and the slide member slides along the slide surface in the direction opposite to the one direction. During this sliding, the other end of the locking member slides up the hole and the sliding member moves in the reverse direction, and finally the shoji rises up and the falling window is closed.

  Such a sliding window locking mechanism for falling windows is constructed on either side of the vertical frame of the sliding window or the vertical frame of the window frame, and the component parts thereof are the conventional window frames disclosed in Patent Document 1 The number is smaller than that of the inset window holding device of the inverted window in which each mechanism is configured on both the side and the side of the shoji. For this reason, the rise in the product cost of the falling window can be suppressed. Moreover, the space which comprises the shoji fall angle locking mechanism of a fall window should just be ensured to one side by the side of a window frame or a shoji side, and it becomes possible to attain thickness reduction of the frame which comprises a fall window.

  Further, the present invention is characterized in that the slide rail is formed with a plurality of holes along the slide direction of the slide surface in accordance with the plurality of tilt angles of the shoji.

  According to this configuration, the other end of the lock member is engaged with the holes at a plurality of places on the slide surface, and the slide members are engaged at a plurality of places on the track, so one end of the arm is held at multiple angles at multiple stages. Ru. Therefore, the shoji is held at a plurality of falling angles by the arm and falls down in multiple steps, and it becomes possible to select a plurality of opening amounts of the falling window.

  The invention is also characterized in that the unlocking member has a length such that the tip reaches the farthest of the plurality of holes.

  According to this configuration, since the tip of the lock release member reaches the farthest hole of the plurality of holes, each engagement state between the plurality of holes formed in the slide surface and the other end of the lock member is the lock All can be released by the tip of the release member. Therefore, each engagement state between each hole and the other end of the lock member is in the order from the hole closest to the unlocking member in the retracted position to the hole farthest away from the unlocking member in the retracted position , By the tip of the unlocking member. When the engagement between the most distant hole and the other end of the lock member is released, the movement of the slide member at the end of the track of the slide rail is restricted, and the shoji is kept in the most fallen state.

  The present invention is also characterized in that the unlocking member has a length such that the tip reaches a hole located closer to one of the plurality of holes.

  According to this configuration, the tip of the lock release member reaches the hole located at a position closer to one than the farthest one of the plurality of holes, so that the unlocking of the plurality of holes formed in the slide surface is released. The engagement between the hole other than the hole farthest from the member and the other end of the lock member can be released by the tip of the lock release member. Therefore, each engagement state between each hole and the other end of the lock member moves from the hole closest to the unlocking member in the retracted position to the hole closest to the hole farthest away from the hole The tips of the unlocking members are released in order of leaving the unlocking members in position. For this reason, in the case of the shoji, the tilt angle determined by the position of the slide member with which the farthest hole and the other end of the lock member engage is most inclined. In the engagement state between the most distant hole and the other end of the lock member, the fallen shoji is raised to swing one end of the arm in the reverse direction, and the slide member slides along the slide surface in the direction opposite to the one direction. Then, the other end of the locking member is released by sliding up the most distant hole. After that, by further raising the fallen shoji, the other end of the lock member is moved to the closest hole by the reverse slide of the slide member accompanying the further swing in the reverse direction of the end of the arm. Slide up each hole in order. Finally, Shoji stands up and the falling window is closed.

Moving. Movement of the unlocking member in one direction against the biasing force of the second elastic member is achieved by the first convex portion of the unlocking member coming into contact with the surface of the rail cap that determines the unlocking position of the unlocking member. , Locked in unlocked position. In the unlocked position, the unlocking member pushes up the other end of the locking member, the tip of which is engaged with the hole, from the hole of the slide surface to release the engagement of the other end of the locking member. In addition, the movement of the unlocking member in the direction opposite to the one direction is stopped at the retreating position by the second convex portion of the unlocking member being in contact with the surface of the rail cap that determines the retreating position of the unlocking member. The unlocking member is held at the retracted position by the biasing force of the second elastic member.

Also, the present invention is

  As shown in FIG. 3, the rear end 15b of the unlocking plate 15 is bent to form a bent portion. The pin 26 is passed through the pair of holes formed in the bent portion and the through holes formed in the resin latch member 16, and the latch member 16 is attached to the rear end 15b by being pinched by the bent portion. The rear end 15b to which the latch member 16 is attached is retractably housed in a space 18c formed in a rectangular shape in the resin rail cap 18, and the side surfaces 18d and 18d are closed by the latch cover 18e. The attachment of the latch cover 18e to the side surfaces 18d, 18d is performed by a pair of countersunk screws 27, 27. Further, a slide groove 18f is formed between the blocks forming the side faces 18d, 18d, and the portion directly below the rear end 15b of the lock release plate 15 is fitted into the slide groove 18f, and the movement of the lock release plate 15 is guided. Ru.

  The bent portion formed at the rear end 15b of the lock release plate 15 forms a first convex portion, and when the lock release plate 15 moves downward, contacts a surface 18g formed in a rectangular shape in the space 18c. The surface 18g abuts on a first convex portion provided on the rear end 15b of the lock release plate 15, and constitutes a surface that defines the lock release position of the lock release plate 15. Further, on the abdomen of the lock release plate 15, convex portions 15c, 15c protruding to both sides are provided as second convex portions. When the lock release plate 15 moves upward, the convex portions 15 c and 15 c abut on the bottom surface of the rail cap 18. The bottom surface of the rail cap 18 constitutes a surface that abuts on the second convex portion to define the retracted position of the lock release plate 15.

  The lock release plate 15 is guided by a slide groove 18 f formed in the rail cap 18 and a track 11 e formed in the slide rail 11 to move the slide surface 11 f. The unlocking plate 15 has a length such that the tip 15a reaches the hole 11g located closer to one of the plurality of holes 11g and 11h than the farthest hole 11h. Movement of the unlocking plate 15 in one direction against the biasing force of the latch spring 17 is provided at the rear end 15b of the unlocking plate 15 on the surface 18g of the rail cap 18 which determines the unlocking position of the unlocking plate 15. When the bent portion abuts, it is stopped at the unlocking position. In the unlocking position, the lock release plate 15 pushes up the other end of the lock member 13 engaged with the hole 11g from the hole 11g of the slide surface 11f to the hole 11g of the other end of the lock member 13 at the lock release position. Disengage the. Further, the movement of the unlocking plate 15 in the direction opposite to the one direction is achieved by the convex portions 15c, 15c of the unlocking plate 15 coming into contact with the bottom surface of the rail cap 18 which determines the retreat position of the unlocking plate 15. It is stopped at the retreat position, and the unlocking plate 15 is held at the retreat position by the biasing force of the latch spring 17.

  On the bottom surface of the space 18 c formed in the rail cap 18, a columnar support 18 h is provided which is fitted to one end of the latch spring 17 to support one end thereof. The other end of the latch spring 17 abuts on the bottom surface of the latch member 16, and the elastic force causes the latch member 16 to project from the upper end surface 18 a of the rail cap 18, that is, the upper surface of the upper collar 4 c of the shoji 4.

  The latch member 16 is provided at the rear end 15b of the lock release plate 15 so that the surface on the outdoor side is curved so as to protrude from the outer shape of the rear end 15b of the lock release plate 15 as shown in FIGS. . The latch member 16 is urged in a direction to project from the upper rod 4c of the shoji 4 by the urging force of the latch spring 17, and the outer side surface of the latch member 16 abuts on the upper frame 3c of the window frame 3 when the shoji 4 is closed. As it is pushed down, it falls to the upper collar 4 c side of the shoji 4 and is accommodated in the space 18 c formed in the rail cap 18 together with the latch spring 17. Thereafter, when the latch member 16 reaches the latch receiver 29 (see FIG. 6) constituting the engaged portion formed on the upper frame 3c of the window frame 3 after the shoji 4 is closed, the biasing force of the latch spring 17 It projects from the upper collar 4c of the shoji 4 and engages with the latch receiver 29 as shown in FIG. 6 (a).

  Below the convex portions 15c, 15c formed in the lock release plate 15, two holes 15d, 15d are formed. Two countersunk screws 28 and 28 are passed through the holes 15d and 15d, and the countersunk screws 28 and 28 are screwed into the two female screw holes 19a and 19a formed at the end of the operation lever 19, thereby releasing the lock. The end of the operation lever 19 is fixed to the plate 15. The control lever 19 is formed by bending a stainless steel plate, and is extended from the lock release plate 15 to the indoor side as shown in FIG. The control lever 19 constitutes a lock release operating member that moves the lock release plate 15 along the slide surface 11 f to the lock release position against the biasing force of the latch spring 17. When the latch lever 16 is operated in one direction against the biasing force of the latch spring 17 and the latch member 16 does not fall to the upper collar 4 c side of the shoji 4, the latch member 16 is engaged with the latch receiver 29, It will not be released. Therefore, the window frame 3 is held closed by the shoji 4 by the engagement of the latch member 16 with the latch receiver 29.

  When the shoji 4 is opened, one end of the hinge arm 6 is swung by its own weight and the one end of the hinge arm 6 is swingably supported. The slide piece 12 moves on the track 11 d of the slide rail 11 downward in one direction. At this time, the lock member 13, one end of which is rotatably attached to the slide piece 12, is urged toward the slide surface 11 f of the slide rail 11 by the lock spring 14 at the other end, and slidably contacts the slide surface 11 f. When the shoji 4 falls down to a predetermined angle, the other end of the lock member 13 is fitted into the holes 11g and 11h opened in the slide surface 11f and engaged with the holes 11g and 11h. Therefore, movement of the slide piece 12 in one direction is blocked, and the hinge arm 6 whose one end is supported by the slide piece 12 is at a position where the movement of the slide piece 12 is blocked as shown in FIGS. The shoji 4 which is held and supported by the hinge arm 6 is held in a fallen state at a predetermined angle.

  The unlocking plate 15 is always biased by the latch spring 17 and held at a retracted position where the leading end 15a located at the leading end does not reach the hole 11g when moving in one direction. In a state where the shoji 4 has fallen to a predetermined angle as shown in FIG. 6B, the operation lever 19 is operated, and the unlocking plate 15 resists the biasing force of the latch spring 17 along the slide surface 11f. When moved in the direction, the tip end 15a of the unlocking plate 15 reaches the hole 11g located closer to one of the plurality of holes 11g and 11h than the farthest hole 11h. Then, the tip end 15a of the lock release plate 15 pushes up the other end of the lock member 13 from the hole 11g. Of the holes 11g and 11h formed on the slide surface 11f, the engagement state between the hole 11g excluding the hole 11h farthest from the unlocking plate 15 and the other end of the locking member 13 is thus the unlocking plate It can be solved by the fifteen tips 15a.

  Although the case where there are two holes 11g and 11h in the slide surface 11f is described in this embodiment, the case where the slide surface 11f between the holes 11g and 11h has a hole (not shown) and three or more holes. However, each engagement state between each hole and the other end of the lock member 13 is one position closer than the hole 11 h farthest from the hole 11 g closest to the lock release plate 15 in the retracted position. The holes are released by the tip 15a of the unlocking plate 15 in the order of separation from the unlocking plate 15 in the retracted position. For this reason, in the case of the shoji 4, the falling angle shown in FIG. 7, which is determined by the position of the slide piece 12 engaged with the farthest hole 11 h and the other end of the lock member 13, is most inclined. In the engaged state between the most distant hole 11 h and the other end of the lock member 13, the fallen sash 4 is raised to swing one end of the hinge arm 6 in the reverse direction, and the slide piece 12 moves in the opposite direction to one direction. By sliding along the slide surface 11 f, the other end of the lock member 13 slides up the hole 11 h farthest from the other to be released. Thereafter, by further raising the fallen shoji 4, the other end of the lock member 13 is closest to the slide of the slide piece 12 in the reverse direction due to the further swinging of the one end of the hinge arm 6 in the reverse direction. The holes are sequentially slid up to the holes 11g in the position. Finally, the shoji 4 stands up, and the falling window is in the closed state shown in FIG.

  However, when the slide surface 11 f has three or more holes, and the tip 15 a of the lock release plate 15 is set to a length that reaches the hole at a position far from the retreat position, the lock release plate 15 is at the retreat position. In some cases, it is conceivable that the rear end 15 b greatly protrudes from the upper ridge 4 c of the shoji 4. Therefore, in this case, the latch member 16 can not be provided at the rear end 15 b of the lock release plate 15. In addition, when it is not appropriate that the rear end 15b greatly protrudes from the upper collar 4c of the shoji 4a, the lock release plate 15 is made of a thin steel plate or wire rod which can be wound up, and the rear end 15b is twisted. By winding the rear end 15b, it is possible to eliminate the disadvantage that the rear end 15b largely protrudes from the upper weir 4c.

  Further, the other end of one hinge arm 6 is connected to a hinge arm damper mechanism 31 shown in FIGS. 6 and 7 provided on the surface of the left vertical frame 3a of the window frame 3 facing the left vertical rod 4a of the shoji 4 It is done.

  In the case of the inward sliding window locking mechanism 1 for the inward turning window 2 according to the present embodiment, the conventional opening state of the inward turning window in which each mechanism is configured on both the window frame side and the shoji side disclosed in Patent Document 1 Unlike the holding device, it is configured on one side of the shoji 4 and its components are less than in the prior art. For this reason, it is possible to suppress an increase in the product cost of the inverted window 2. In addition, the space that constitutes the shoji fall angle lock mechanism 1 of the inward turning window 2 may be secured on one side of the shoji 4 side, and it is possible to make the frame which constitutes the inward turning window 2 thinner.

  Further, in the case of the sliding door tilt angle lock mechanism 1 of the internally-inverted window 2 according to the present embodiment, the operation on the lock release plate 15 can be performed by the operation lever 19 provided to extend indoors from the lock release plate 15. For this reason, the operation of the lock release plate 15 can be easily performed, and furthermore, since the operation on the outdoor side beyond the shoji 4 is not necessary, the operation can be performed safely.

  In the above embodiment, the case where the lock release plate 15 is moved along the slide surface 11 f using the operation lever 19 has been described. However, the lock release plate 15 may be directly moved along the slide surface 11 f without using the operation lever 19.

  Moreover, in said embodiment, although the case where the shoji fall angle lock mechanism 1 and 1 of the inner fall window 2 were provided in vertical weir 4a, 4b of the shoji 4 in the vertical frame 3a, 3b of the window frame 3 was demonstrated. You may comprise so that it may provide in the opposing surface which opposes the vertical weirs 4a and 4b of the shoji 4. In this case, one end of the hinge arm 6 on the side of the sliding door fall angle lock mechanism 1 swings upward in one direction when the front door 4 is opened. Therefore, in this case, the shoji fall angle lock mechanism 1 shown in FIG. 3 is turned upside down and attached to the vertical frames 3a and 3b, and the other end of the lock member 13 is a hole 11g by the upward movement of the slide piece 12. , 11h. Further, in this case, the latch member 16 projecting from the upper end surface 18a of the rail cap 18 is not provided at the rear end 15b of the unlocking plate 15, and the rear end 15b does not protrude from the upper end surface 18a of the rail cap 18 Formed as. Further, the hinge arm damper mechanisms 31 and 31 are provided on the side of the shoji 4. With such a configuration as well, the components of the inward sliding window locking mechanism 1 for the inward turning window 2 are smaller than those in the related art, and the same function and effect as those of the above-described embodiment can be obtained.

  In the above embodiment, in the case where the unlocking plate 15 has a length such that the tip 15a reaches the hole 11g located closer to one of the plurality of holes 11g and 11h than the farthest hole 11h, explained. However, the unlocking plate 15 may be configured to have a length such that the tip 15a reaches the farthest hole 11h of the plurality of holes 11g and 11h.

  According to this configuration, since the tip 15a of the lock release plate 15 reaches the farthest hole 11h of the plurality of holes 11g and 11h, the plurality of holes 11g and 11h formed in the slide surface 11f and the lock member 13 The respective engagement states with the other end can all be released by the tip 15 a of the unlocking plate 15. Therefore, the engagement states between the holes 11g and 11h and the other end of the lock member 13 are from the hole 11g closest to the unlocking plate 15 at the retreating position to the retreating position from the hole 11h farthest away The tip end 15 a of the unlocking plate 15 releases the unlocking plate 15 in the order of separation from the unlocking plate 15. When the engagement state between the farthest hole 11h and the other end of the lock member 13 is released, the movement of the slide piece 12 at the end of the track 11d of the slide rail 11 is restricted, and the shoji 4 falls most Will be held by

  Further, the hole formed in the slide surface 11 f may be, for example, one hole 11 g. In this case, the operating lever 19 is operated in a state where the shoji 4 has fallen to a predetermined angle as shown in FIG. 6 (b), and the unlocking plate 15 resists the biasing force of the latch spring 17 on the slide surface 11f. When it is moved along one direction, the unlocking plate 15 has its movement limited at the end of the track 11d of the slide rail 11, and stops. Therefore, the hinge arm 6 whose one end is supported by the slide piece 12 is held at a position at which the slide piece 12 is stopped, and the shoji 4 supported by the hinge arm 6 is kept in the most fallen state. In this state, when the folded tongue 4 is raised, one end of the hinge arm 6 swings in the reverse direction, and the slide piece 12 slides along the slide surface in the direction opposite to the one direction. During this slide, the other end of the lock member 13 slides up the hole 11g to move the slide piece 12 in the reverse direction, and finally the shoji 4 stands up and the inverted window 2 is shown in FIG. It is closed.

  In the above embodiment, the rear end 15b of the unlocking plate 15 is protruded from the upper collar 4c of the shoji 4 and the latch member 16 is provided on the rear end 15b to latch the shoji 4 on the window frame 3 The structure provided with the shoji fall angle lock mechanism 1 has been described. However, the shoji fall angle lock mechanism 1 does not necessarily have to have such a latch mechanism. For example, such a latch mechanism may be provided at the center of the upper collar 4 c of the shoji 4 separately from the shoji fall angle lock mechanism 1.

  In the above embodiment, the holes 11g and 11h are provided on the slide surface 11f of the slide rail 11. However, instead of the unlocking plate 15, the lock position control member (not shown) attached to the slide rail 11 is used. You may comprise so that it may provide. The lock position control member is formed, for example, of a thin steel plate which can be wound by winding a coil on the side of the rear end corresponding to the rear end 15 b of the unlocking plate 15 and is movable along the slide surface 11 f of the slide rail 11 Attached to the slide rail 11 and extends along the slide surface 11 f. Then, a hole is opened at a predetermined position on the side of the tip corresponding to the tip 15 a of the lock release plate 15. Further, a slide position fixing member for fixing the slide position of the hole opened in the lock position control member with respect to the slide rail 11 at an arbitrary position is provided using, for example, a screw or the like. In this case, the sliding lever 11 with the holes 11g and 11h, the slide piece 12, the lock member 13, the lock spring 14, the lock position control member and the slide position fixing member Configured

  In this configuration, the slide position of the hole opened in the lock position control member relative to the slide rail 11 is set in advance according to the desired tilt angle of the shoji 4 and the position is fixed by the slide position fixing member. Keep it. When the shoji 4 is opened, one end of the arm 6 swings, and the slide piece 12 swingably supporting one end of the arm 6 moves the track 11 e of the slide rail 11 in one direction. At this time, the other end of the lock member 13 whose one end is rotatably attached to the slide piece 12 is urged toward the lock position control member by the lock spring 14 and slidably contacts the lock position control member. When the shoji 4 falls to a desired falling angle, the other end of the lock member 13 is fitted into a hole opened in the lock position control member and engaged with this hole. Therefore, the movement of the slide piece 12 in one direction is blocked, and the arm 6 supported at one end by the slide member 13 is held at the position at which the movement of the slide piece 12 is blocked. Is held in the state of falling to the desired falling angle.

  When the lock position control member is released by the slide position fixing member and the lock position control member is moved in one direction along the slide surface 11 f of the slide rail 11 in a state where the shoji 4 falls to a desired falling angle, the lock is performed. The other end of the member 13 is pushed up from the hole. Therefore, when the lock position control member is moved further in one direction along the slide surface 11 f of the slide rail 11 from this state, the lock position control member is opened. The hole also moves in one direction. Therefore, the movement of the hole in one further direction is stopped at a position corresponding to the desired second falling angle of the shoji 4, and the locking position control member is fixed at that position by the slide position fixing member, thereby moving the shoji 4. Further, it can be held at the desired second falling angle. By repeating this operation, the shoji 4 can be held at a plurality of desired falling angles.

  On the other hand, when the shoji 4 is raised from a state of falling down to one of the falling angles, one end of the arm 6 swings in the reverse direction, and the slide piece 12 slides in the opposite direction to one direction. During this sliding, the other end of the lock member 13 slides on the flat side of the lock position control member, the slide piece 12 moves in the reverse direction, and finally the shoji 4 stands up and the inward fall window 2 is closed. become.

  Such a shoji fall angle lock mechanism of the inner folding window 2 is also formed on the side of the longitudinal ridges 4a and 4b of the shoji 4 and the component parts thereof are the conventional window frame side and shoji side disclosed in Patent Document 1 In each case, each mechanism is configured in less than the inward opening window holding device of the inward opening window. For this reason, it is possible to suppress an increase in the product cost of the inverted window 2. Moreover, the space which comprises the shoji fall angle locking mechanism of the inward turning window 2 should just be ensured to one side of the shoji 4 side, and it becomes possible to attain thickness reduction of the frame which comprises the inward turning window 2. FIG.

  Although said embodiment demonstrated the case of the inward turning window 2 in which the falling window falls to indoor side, the falling window may be an outturning window which falls to the outdoor side. In this case, the latch member 16 protrudes from the outer shape of the rear end 15 b of the lock release plate 15, and the surface on the indoor side is curved and provided on the rear end 15 b of the lock release plate 15.
