Description

[Detailed description of the invention] [Industrial application field] The present invention is a sliding sliding sash, specifically a guide device that guides a movable shoji when the movable shoji is moved out of a window frame or stored. This invention relates to a locking device that fixes the movement of an operating rod after a movable shoji has jumped out of a window frame.

[Conventional technology]

As a pop-out sliding sash, for example, the one shown in FIG. 11 is known.

In other words, the fixed shoji 2 and the movable shoji 3 are arranged in the window frame 1 so as to be on the same plane in the out-of-plane direction, and the window frame 1
The vehicle frame 7 of the door roller device 6 is attached to the indoor rail 5 of the lower frame 4 of the
is movable via wheels (not shown), and a link 8 pivotally connected to the vehicle frame 7 so as to be rotatable in an out-of-plane direction is pivotally connected to the lower part of the movable shoji 3, so that the movable shoji An operating rod 9 that is moved by a supported handle is pivotally connected to the link 8, and by rotating the handle and moving the operating rod 9, the link 8 is rotated in the direction of arrow a, thereby moving the movable shoji 3. is moved parallel to the indoor side in an out-of-plane direction as shown by arrow b, and in this state, the movable shoji 3 runs in the in-plane direction along with the door roller device 6 along the indoor side rail 5, and overlaps with the fixed shoji 2. .

In such a sliding sliding sash, it is necessary to move the movable shoji 3 in parallel between the state in which it is housed in the window frame 1 and the state in which it protrudes toward the indoor side in an out-of-plane direction. A guide device is provided throughout.

For example, a guide device disclosed in Japanese Utility Model Application Publication No. 60-184973 is known.

That is, as shown in FIG. 12, the guide lever 12 is slidably fitted into the guide groove 11 of the base 10 provided at the lower part of the movable shoji 3, and the guide lever 12 is fitted into the guide block 13 provided on the lower frame 4. The movable shoji 3 is slidable along the guide lever 1.
2. A guide block 13 allows for parallel movement.

Furthermore, if you accidentally turn the handle and move the operating rod 9 when moving the movable shoji 3 along the rail 5 after jumping out, the link 8 will rotate in the opposite direction to the arrow a, causing the movable shoji 3 to move. may move to the fixed shoji 2 side and interfere with it.
It is necessary to lock the device so that it does not move, and a known locking device is disclosed in, for example, Japanese Utility Model Application No. 60-184973.

That is, as shown in FIG. 12, a lock lever 14 is supported by a pin 15 on a movable shoji 3 so as to be able to swing up and down, and a hook piece 16 is provided at one end of the lock lever 14, and an inclined cam contact piece 17 is provided at the other end. At the same time, a locking portion 18 is provided on the operating rod 9, a cam piece 19 is provided on the window frame 1, and the lock lever 14 is biased to swing by a spring 20 to engage the hook piece 16 with the locking portion 18 for operation. Make sure that the rod 9 does not move, and move the movable shoji 3
When the cam is closed and moved to the pop-out position, the piece 1 per cam will be removed.
7 comes into contact with the cam piece 19, and the lock lever 14 swings in the direction against the spring 20, whereby the hook piece 16
is separated from the locking portion 18 so that the operating rod 9 can move.

[The problem that the idea attempts to solve]

In the above guide device, the base 10 and the guide lever 12 slide, so if the movable shoji 3 is moved and strongly hits the vertical frame, the sliding parts of the base 10 and the guide lever 12 will receive a strong impact and deform. The base 10 and guide lever 1 may be
2 may not be able to slide smoothly, and the movable shoji 3 may not be able to move smoothly in parallel.

With the aforementioned locking device, the cam contact piece 17 rides on the cam piece 19 to swing the lock lever 14 and release the lock, so when the movable shoji 3 is jumped out, the cam contact piece 17 interferes with the cam piece 19. In addition, the cam contact piece 17 must ride on the cam piece 19 even when the movable shoji 3 is stored.

For this reason, the pop-up stroke of the movable shoji 3 is determined by the length of the cam piece 19, and in order to increase the pop-up stroke, it is necessary to lengthen the cam piece 19, so when trying to obtain a large pop-up stroke, The cam piece 19 protrudes from the window frame 1, resulting in poor appearance.

SUMMARY OF THE INVENTION An object of the present invention is to provide a guide device and a lock device for a sliding sash that can solve the above-mentioned problems.

[Means and actions for solving the problem]

1. A guide lever 53 is rotatably supported by a vertical pin 52 on a mounting base 51 provided on a movable shoji 23,
This vertical pin 52 is slidable along a guide long groove 57 formed in the mounting base 51, and the spring 5
A guide pin 59 is provided on the guide lever 53, and a support arm 56 is pivotally supported by a pin 55 in the middle in the longitudinal direction, and this support arm 56 is attached to the mounting base 5.
1 is rotatably supported by a pin 54, and the window frame 21 has a guide groove 6 having a substantially L-shaped planar shape.
This is a sliding sliding sash in which a guide block 50 having a diameter of 0 is attached, and the guide pin 59 is slidably moved in and out of this guide groove 60 to constitute a guide device 34.

As a result, the guide lever 53 is attached to the mounting base 5.
1, the guide pin 59 rotates so as to move linearly with respect to the guide groove 6.
Since the mounting base 51 can be moved in parallel while being held at the corner portion 60a of 0, the movable shoji 23
can be guided to move in parallel between a storage position and a pop-out position.

Further, when the guide pin 59 is inserted into the guide groove 60 and collides with the corner portion 60a, the guide lever 53 rotates and can absorb part of the impact force, and part of the impact force is transmitted through the support arm 56. Since the movement is transmitted to the mounting base 51, the movable shoji 23 can be smoothly translated in parallel without damaging any parts.

2. On a mounting base 51 provided on the movable shoji 23, a longitudinally intermediate portion of a guide lever 53, which is provided with a guide pin 59 on one longitudinal end side and a push portion 53a on the other end side, is rotatably supported by a vertical pin 52. Then, the vertical pin 52 is provided so as to be slidable along a long guide groove 57 formed in the mounting base 51 and is biased to slide in one direction by a spring 58, so that the vertical pin 52 is inserted between the guide lever 53 and the mounting base 51. A guide block 50 which pivotally connects the support arm 56 to restrict rotation of the guide lever 53, and has a guide groove 60 in the window frame 21 having a substantially L-shaped planar shape and through which the guide pin 59 slides in and out.
A lock lever 64 having a locking portion 67 at one end is rotatably provided adjacent to the guide lever 53 on the mounting base 51, and the lock lever 64 is biased to rotate in one direction by a spring 66. , and the lock lever is configured to be rotated in the other direction by the push portion 53a of the guide lever 53, and is a moving member that operates the pop-up device 31 that moves the movable shoji 23 between the pop-out position and the storage position. A sliding sliding sash constitutes a locking device 32 by providing an engaging pin 68 that engages with a locking portion 67 of 64 so as to engage with the locking portion 67 when the movable shoji 23 is in the projected position.

As a result, when the movable shoji 23 moves to the jumping position, the lock lever 64 rotates in one direction and the locking portion 67 engages with the locking pin 68 to lock the movement of the operating member of the jumping device. Even if the handle is operated by mistake when moving the movable shoji 23 from side to side, the operating member will not move, so it is possible to prevent the movable shoji 23 from interfering with the fixed shoji.

In addition, by changing the length of the long guide groove 57 on which the vertical pin 52 of the guide lever 53 slides, the linear movement distance of the guide pin 59 can be changed and the pop-up stroke of the movable shoji can be changed, so the pop-up stroke can be changed without spoiling the appearance. This allows you to make larger strokes.

The movable shoji 23 is movable in parallel between a storage position and a pop-out position, which are flush with each other, and is movable from side to side in a position overlapping the fixed shoji 22. Left and right hard frames 26,2
Glass is installed inside the frame assembly which has a rectangular shape, and a handle 27 is provided on the left side rigid frame 26, and by rotating this handle 27, each frame can be adjusted as shown in Fig. 1. A provided operating rod 28 is movable.

In other words, the operating rods 28 provided on each frame are continuous around the corner connectors 29 four times.

As shown in FIG. 1, the lower stile 25 has a door roller 3.
0, a jumping-out device 31, and a locking device 32 are provided, and a guide device 34 is provided extending between the lower stile 25 and the lower frame 33.

The door wheel 30 is provided with a pair of wheels 36 on a door wheel frame 35, and the pair of wheels 36 can run along a rail 37 of the lower frame 33.

As shown in FIGS. 1 and 10, the jumping device 31 includes a link 39 rotatably supported on the lower stile 25 with a vertical shaft 38, and one end of this link 39 is attached to the door frame 35 with a vertical shaft 40. A long hole 41 is formed at the other end, and a guide pin 43 provided on an arm 42 connected to the operating rod 28 is fitted into the long hole 41, as shown by the solid line in FIG. As shown in FIG. 5, when the operating rod 28 is moved from the storage position in the direction of arrow c in FIGS. 1 and 10, the link 39 rotates and jumps out as shown in the imaginary line in FIG. 10 and in FIG. While moving the operating rod 28 in parallel to the position shown in FIG.
When moved in the direction opposite to arrow c in FIG. 10, it returns to the storage position.

As shown in FIGS. 1 to 4, the guide device 34 includes a guide block 50 fixed to the lower frame 33.
, a mounting base 51 attached to the lower stile 25, a guide lever 53 swingably supported on the mounting base 51 with a vertical pin 52, and a pivoting connection between the mounting base 51 and the guide lever 53 with pins 54 and 55. The vertical pin 52 is slidable along the long guide groove 57 of the mounting base 51, and is biased to slide in one direction by a spring 58. A guide pin 59 is provided on one end side, and the guide pin 59 can slide in and out of a substantially planar L-shaped guide groove 60 formed in the guide block 50. A semicircular protrusion 61 of the pin 59 engages with a protrusion 62 of the guide groove 60 to prevent it from coming off.

As shown in FIGS. 1 to 4, the lock device 32 has a lock lever 64 rotatably supported on the mounting base 51 by a pin 65, and the lock lever 64 is supported in one direction by a spring 66, that is, as shown in FIG. A locking portion 67 formed at one end of the arm 42 is biased to rotate in the direction of arrow d in FIGS. 3 and 4.
The arm 42 engages with a locking pin 68 provided in the
The movable shoji 23 is prevented from moving in the direction of movement toward the storage position, and the push portion 53a on the other end side of the guide lever 53 is pressed against the lock spring 64.
The lock lever 64 is brought into contact with the other end so that it can be rotated in the other direction against the spring 66, that is, in the direction opposite to the arrow d in FIGS. 2, 3, and 4.

As such, the guide lever 53 rotates around the vertical pin 52, but its rotation is restricted by the support arm 56, and the vertical pin 52 resists the spring 58 and rotates along the guide long groove 57. Therefore, the guide lever 53 rotates so that the guide pin 59 moves linearly, and when no external force is applied, the guide lever 53 is biased in one direction by the force of the spring 58 as shown in FIG. There is.

When the movable shoji 23 is in the storage position, the fourth
5, the guide pin 59 is inserted into the guide groove 60 and the semicircular protrusion 61 is inserted into the protrusion 62
The vertical pin 52 is held against the spring 58 so as not to come off, and the vertical pin 52 has moved slightly to the right against the spring 58.

At this time, the lock lever 64 is operated by the spring 66 as shown in FIG.
The guide lever 53 is rotated in the direction of the arrow d in FIGS. 3 and 4, and its longitudinally intermediate portion is in contact with the locking pin 68.
4, the locking device 32 does not lock movement of the actuating rod 28.

When the handle 27 is rotated in this state, the operating rod 28 moves in the direction of the arrow c in FIGS. 1 and 10, and the movable shoji 23 is moved out of plane toward the indoor side by the jumping device 31.

As a result, the mounting base 51 is moved as shown by the arrow e in FIG.
As shown in , the guide lever 53 relatively rotates in the direction of arrow A, and the guide pin 59 rotates in the direction of arrow B, causing the semicircular protrusion 61 to move toward the interior side of the room together with the movable shoji 23. 62 and moves toward the indoor side along the guide groove 60, the guide pin 59 moves into the guide groove 60 as shown by the imaginary line in FIG.
It abuts against the corner portion 60a of.

At this time, the vertical pin 52 slides along the guide long groove 57 and the guide pin 59 moves linearly, so the mounting base 51 can move in parallel, and the movable shoji 23 is shown in FIGS. 6 and 7. Can move in parallel to the jump position.

Further, by lengthening the guide groove 57 and increasing the sliding distance of the vertical pin 52, the linear movement distance of the guide pin 59 can be increased and the pop-out stroke of the movable shoji can be increased.

On the other hand, since the arm 42 moves together with the operating rod 28 while the movable shoji 23 moves to a predetermined jumping position, the locking pin 68 is at a position facing the locking portion 67 of the lock lever 64 as shown in FIG. At the same time, the lock lever 64 moves to the guide lever 53.
The locking portion 67 and the locking pin 68 are separated from each other by being pushed by the pushing portion 53a and rotated in a direction against the spring 66.

In this state, move the movable shoji 23 to the rail 37 of the lower frame 4.
When the guide pin 59 moves to the right along the guide groove 60, the guide pin 59 separates from the guide groove 60 and enters the state shown in FIG.

As a result, one end of the guide lever 53 becomes free, so the guide lever 53 is rotated in the direction of the arrow C by the spring 58, and is rotated in the direction of the arrow D by the lock lever 64. is rotated in the direction of arrow d as shown in FIG.
8.

For this purpose, move the operating rod 28 in the opposite direction to arrow c.
In other words, the movable shoji 23 cannot be moved in the direction toward the fixed shoji, and even if the handle 27 is rotated in the opposite direction, the operating rod 28 does not move, so the movable shoji interferes with the fixed shoji. This can be prevented.

Furthermore, when the movable shoji 23 is moved to the left from the state shown in FIG. 8 and comes into contact with the vertical frame, the guide lever 53
The guide pin 59 slides along the oblique entrance/exit portion 60b of the guide groove 60 and comes into contact with the corner portion 60b as shown in FIG. The lock lever 64 is rotated at the portion 53a in the direction opposite to the direction of the arrow d, and the locking portion 67 is disengaged from the locking pin 68, so the operating rod 28 is moved in the direction opposite to the arrow c using the handle 27 to close the movable shoji 23. In addition, when the guide pin 59 strongly collides with the guide groove 60, the impact force can be absorbed by the rotation of the guide lever 53, and a part of the impact force is transferred to the mounting base via the support arm 56. 51, it is possible to smoothly move the movable shoji in parallel between the storage position and the pop-up position without causing play in each part.

[Effect of idea]

1. The guide lever 53 rotates so that the guide pin 59 moves linearly with respect to the mounting base 51, so the mounting base 51 can be moved in parallel while the guide pin 59 is held in the corner part 60a of the guide groove 60, so it is movable. The shoji 23 can be guided to move in parallel between the storage position and the pop-up position.

Further, when the guide pin 59 is inserted into the guide groove 60 and collides with the corner portion 60a, the guide lever 53 rotates and can absorb part of the impact force, and also absorbs part of the impact force via the support arm 56. Since the movement can be transmitted to the mounting base 51, the movable shoji 23 can be smoothly translated in parallel without damaging any parts.

2 When the movable shoji 23 moves to the pop-up position, the lock lever 64 rotates in one direction and the locking portion 67 engages with the locking pin 68 to lock the movement of the operating member of the pop-up device, so the movable shoji Even if you accidentally operate the handle when moving the shoji 23 from side to side, the operating member will not move, so the movable shoji 2
3 can be prevented from interfering with the fixed shoji.

In addition, by changing the length of the long guide groove 57 on which the vertical pin 52 of the guide lever 53 slides, the linear movement distance of the guide pin 59 can be changed and the pop-up stroke of the movable shoji can be changed, so the pop-up stroke can be changed without spoiling the appearance. This allows you to make larger strokes.
