Description

[Detailed explanation of the invention] [Purpose of the invention] "Industrial application field" This invention is for inward folding and horizontal sliding (transferring the shoji in parallel to the wall surface toward the indoor side). The present invention relates to the structure of a metal sash that performs.

``Prior Art'' Conventionally, there is a sash in which a fitting part and a movable shoji are arranged adjacent to each other in a window frame, and the frame material of the fitting part and the outer member of each frame of the movable shoji are on the same surface. In this case, there are movable shoji that can simply be folded inward, and others that can be moved inward and pulled horizontally to a position parallel to the indoor side. Conventionally, including sashes in which the fitting part and the outside member of each stile of a movable shoji are on the same plane, the fitting part and the outside surface of the stile of a movable shoji are retracted toward the indoor side against the outside surface of the conventional window frame. It's in the right position.

``Problem that the invention attempts to solve'' In a sash in which an inward-opening shoji part and a movable shoji adjacent to the inward-opening shoji part that can clean the fitting part or the outside surface of the glass of the fitting part are housed in the window frame, the frame material of the fitting part is It is beautiful to make the surfaces of the outer members of each frame of movable shoji the same. However, because the components of the shoji are recessed into the interior of the room relative to the window frame, the aesthetic appearance is impaired, and when the movable shoji is designed to have the functions of folding inward, moving inward, and pulling horizontally, the sills of the shoji are thin. This may cause strain on the device installed, and the large force required to close and pull the movable shoji may cause the stile to become distorted.

This idea is achieved by making the outside surface of the movable shoji flush with the window frame of a window equipped with a part that fits inside the window frame or a shoji part that opens inward, and a movable shoji that can be folded inward, moved inward, and pulled sideways. The aim is to solve conventional problems.

[Structure of the idea]

``Means for solving the problem'' This idea places a movable shoji adjacent to the window frame fitting section or inward opening shoji section, and the movable shoji is attached to the rail provided on the lower frame via an inward device. The lower part engages, one end of the upper part engages with an inward tilting device attached to the upper frame, and an endless operating rod is disposed on the outer periphery of the movable shoji so as to be movable along the outer periphery of the movable shoji. A lock pin is fixed to the window, a tightening handle is provided on the stile to drive the operating lever, and a lock receiver to which the lock pin engages is fixed to the inner periphery of the window frame on the movable shoji side. This window is characterized in that the outer surface of the window frame, the outer surface of the movable shoji, and the outer surface of the fitting part or the inward-opening shoji are on the same plane.

When the pin 115 is separated to the right from the latch 111 and the latch 111 is at the position indicated by the two-dot chain line in FIG. The latch 111 is pressed by the sloped cam part 119, and the latch 111 is pressed by the spring 11.
When the end 114 of the latch passes over the tip 118 of the receiver, the latch 111 moves to the right under the force of the spring 113 and moves to the fifth position.
The latch 111 and the receiver 117 are engaged as shown by the solid line in the figure.

Next, the operation of the movable shoji 5 will be explained as follows. When the window is closed, the inwarding device 66 is in the state shown in FIG. 7, the inwarding device 65 is in the state shown in FIG. 10, and the movable shoji 5 is in the state shown in FIG.
37 is energized toward the outside of the room to seal the space between it and the window frame. Therefore, the seal 19 makes the window watertight, and the seals 22 and 37 further improve watertightness, improve airtightness, and provide soundproofing and heat insulation. Window frame upper frame 1, lower frame 2, vertical frame 3,
The outer surface of the intermediate mullion 4 and the outer surfaces of the frames of the movable shoji 5, the fitting section 6, and the inward opening shoji section 6' are on the same plane.

Such outward biasing of the movable shoji 5 is obtained by pushing the lock pin 71 into the groove of the lock receiver 24.

In the position where the operating handle 62 faces vertically upward (FIGS. 1A, 1B, and 6), the lock pin 71 is in the lock receiver 24, and the movable shoji 5 is closed. When the operating handle 62 is rotated clockwise from this position, the pinion 63 is rotated in the same direction, the rack 64 is raised, and the operating rod 73, which is in the tightened handle position, is raised via the coupling 78 and the stud 77. The operating rod 74 connected to both ends of the operating rod 73 is raised. Operating rod 7
4 moves the operating rod 74 on the upper stile 9 side to the right and moves the operating rod 74 on the lower stile 11 side to the left via the band steel 75, and the same effect is achieved at each other corner.In the end, the stile of the movable shoji 5 is The surrounding operating rods 73, 74 move annularly clockwise in the surrounding groove 34. Operating rods 73, 74
Accordingly, the lock pin 71 is removed from the lock receiver 24. Operating rods 73, 7 for moving the lock pin 71
4, the pin portion 79c of the driver comes into contact with the opening side cam portion 91b of the cam link.

When the operating handle 62 is further rotated clockwise, the pin portion 79c of the driver of the inward tilting device 66 continues to the right in FIG. 7, pushing the cam portion 91b and rotating the cam link 86 counterclockwise about the pin 81. let A pin 84 at the tip of the cam link 86 rotates the stay arm 82 clockwise around a pin 85. At this time, the pin 85 moves along the elongated hole 83, and the stay arm 82 changes its inclination. The movable shoji 5 has a door roller 92 and an attached lower frame rail 54.
The upper part is tilted inwards in Fig. 3 using the treads as bearings. The pin part 79c of the driver is the lock part 8
9 and the lock key portion 79b of the driver engages with the lock portion 86a of the cam link, the stay arm 82 stops rotating and is locked as described above, resulting in the state shown in FIG. In this locked position, the operating handle 62 is rotated 90 degrees and faces horizontally. In this position of the operating handle 62, the pin 115 at the position of the inversion holding device is located close to the latch 111 due to the movement of the lower operating rod 74.

In this way, the movable shoji 5 was tilted inward. Next, we will talk about moving the movable shoji 5 inwards.

When the operating handle 62 is further rotated approximately 30 degrees clockwise, the pin portion 79c of the driver of the inward tilting device
and the cam link lock portion 89, the driver lock key portion 79b, and the cam link lock portion 86a.
The driver 79 moves to the right while maintaining contact with the pin 115, and the pin 115 moves the latch 111 to the left against the spring 113, and the latch 111 and the receiver 117 are disengaged from each other. The operating handle 62 is in a position where it is easy to grasp and apply force. Then, when the operating handle 62 is pulled toward the indoor side, the lower part of the movable shoji 5 moves toward the indoor side around the ball stud 87. At that time, the parallel links 95 and 96 of the lining device each rotate counterclockwise in FIG. It is separated from and parallel to the lower frame 2 of the window frame. The stay link 99 is pulled by the parallel link 95 via the intermediate pin 98, but since the pin 103 is in the cam groove 109 of the stopper, the door roller main body 93 moves to the left, and the pin 103 moves relative to the guide part 10.
Go to the right inside 1 and enter the key-shaped section 102. Torsion spring 1
04, the stay link 99 is biased counterclockwise, so in order for the parallel link 95 to rotate clockwise about the vertical shaft 94, it is necessary to apply a force that causes the pin 103 to escape from the key-shaped portion 102. , 1st
In the state shown in Figure 1, the parallel link 9 is in the parallel link state.
5, 96, the lower stile 11, and the door roller body 93 connected by the round bar 105 are rigidly maintained in the shape of a parallelogram.

In this way, the outer surface of the movable shoji 5 is positioned closer to the indoor side than the indoor side of the stile of the fitting part 6 or the inward-opening shoji part 6', and the lower part of the movable shoji 5 is biased toward the indoor side by the inward movement device 65, making it rigid. Since the upper part of the movable shoji 5 is kept rigid by the stay arm 82 of the inward tilting device 66 by the cam link 86, driver 79, etc., the movable shoji 5 is separated from the rail 54 and kept upright on the indoor side.

When the movable shoji 5 is moved to the right by holding the operation handle 62, the door roller 92 rolls on the rail 54, and the arm guide 88 slides on the guide groove 56. Movable shoji 5
corresponds to the door stop 106, overlaps with the fitting part 6 or the inward-opening shoji part 6', and forms an opening through which the inside and outside pass through adjacent to the fitting part 6 or the inward-opening shoji part 6'.
When the user releases the operating handle 62, the operating handle 62 returns from the downward diagonal direction to the horizontal direction due to a spring (not shown) that biases each operating rod arranged in an annular manner counterclockwise.

When the movable shoji 5 is pulled sideways, press the operating handle 6.
2 and move to the left, the movable shoji 5 overlaps with the opening adjacent to the fitting part 6 or the inward opening shoji part 6'. When the pin 103 at the end of the stay link 99 of the lining device 65 hits the entrance 109a of the groove of the stopper 108 attached to the left end of the lower attachment frame 53, the pin 103 comes off from the jaw of the groove of the key-shaped part 102, and the pin 103 is released. Since the door wheel 92 moves to the right, the straight part of the guide part 101 touches the pin 103 and moves to the right.
The stay link 99 is folded counterclockwise around the pin 103. Due to the leftward inertia of the movable shoji 5 and the bias of the torsion spring 104, the inward moving device 6 is moved through the stay link 99.
5 is folded into the state shown in FIG. When the movable shoji 5 is gently moved to the left, when the operation handle 62 is pushed toward the outside, the vertical shaft 90 is pushed toward the indoor side from the bottom of the movable shoji 5 via the bracket 97. The parallel link 95 receives a force that rotates clockwise around the vertical shafts 94 and 90 to which the parallel link 95 is pivoted, and the stay link 99 is torsioned and the pin 103 is pushed into the key-shaped portion 102 by the torsion spring 104. Push out the pin 103 from the key-shaped part 102 against the force applied,
The door roller 92 is moved to the right and the straight portion of the guide portion 101 is moved to the right.

In this way, the parallel links 95 and 96 are turned clockwise, the door roller body 93 and the bracket 97 approach each other, and the latch 111 moves from the position indicated by the two-dot chain line to the position indicated by the solid line in FIG. Part 1
19, the latch 111 moves to the left against the spring 113, and when the end 114 of the latch passes the tip 118 of the receiver, the latch 111 is pushed by the spring 113 and moves to the right, and the latch 111 and the receiver 117 are engaged, and the movable shoji 5 returns to its inverted state. In this state, the pin 103 of the stay link 99 and the parallel link 95, the vertical shaft 9
Between 0 and 0, the torsion spring 104 is biased in the approaching direction.

Now, when the operating handle 62 is rotated counterclockwise, contrary to what has already been explained, the rack 64 is rotated in a downward ring shape and the operating rods 73, 74 are rotated counterclockwise when viewed from the inside.
moves, the stay arm 82 of the inward tilting device 66 rotates counterclockwise around the pin 85 as already explained, and the movable shoji 5 closes. Operation handle 6
2 further counterclockwise, the lock pin 71
is fitted into the lock receiver 24 and locked, and at this time the gaskets 19, 37 are strongly pressed between the frame of the movable shoji 5 and the window frame, and the gasket 22 is brought into close contact with the airtight portion 48 of each frame.

FIGS. 16 to 18 are front views of other embodiments of the invention as seen from the inside. In Fig. 16, the center of the opening frame is an opening that communicates between the inside and outside and is closed with a movable shoji 5, and the movable shoji 5 has a closing part 6 on both sides, and the movable shoji 5 has a closing part on either side. It is now possible to move to 6. 17th
The figure shows the inward opening shoji part 6' of the fitting part 6 in Fig. 16.
That is. In FIG. 18, a movable shoji 5 is provided on both vertical frame sides of the opening frame as an opening for passing inside and outside, and the center of the opening frame is a fitting part 6 with a width more than twice the width of the movable shoji 5. It is designed so that it can be overlapped with the fitting part 6.

[Effect of idea]

This idea is to provide a window frame with a closing part or an inward-opening shoji part, and placing a movable shoji adjacent to the closing part or an inward-opening shoji part that closes the opening so that the inside and outside can pass through. The lower part engages with a rail provided in the frame via an inward device, the upper part engages with an inward device, and endless operating rods are arranged around the outer periphery of the movable shoji so that they can move along the outer periphery of the movable shoji. In a window, a lock pin is fixed to the operating lever, a tightening handle for driving the operating lever is provided on the stile, and a lock receiver to which the lock pin engages is fixed to the inner periphery of the window frame on the movable shoji side. The outside surface of the window frame, the outside surface of the movable shoji, the outside surface of the frame of the fitting part, or the outside surface of the inward-opening shoji part are on the same plane, and when the window is closed, the window frame and shoji are The fitting part or the inward-opening shoji part has an appearance that is on the same plane and is extremely beautiful, and since the unevenness of the window sash does not easily cause wind eddies, weathering of the outer wall surface progresses slowly. Also, since the heat of the movable shoji can be increased, it is suitable for large-opening windows.

In the embodiment, the packing is provided in three stages, so it is highly watertight, has excellent sound insulation, and the packing has a great damping effect.
