Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window device used in high-rise buildings. still,
Generally, a building with 3 to 5 floors is called a middle-rise building, and anything above that is called a high-rise building, but the term "high-rise building" as used in the present invention refers to relatively tall buildings, including such so-called middle-rise and high-rise buildings.

When installing windows in high-rise buildings, the opening width of the window is
Except for small windows of ~50cm, the opening width is 7.
In the case of large windows (m2 or larger), if you make the window shoji easy to open, it is very dangerous, such as people accidentally falling out of the window or the shoji being unable to close due to wind pressure when opened. For this reason, when installing a window shoji by fitting it into a window frame, it is necessary to use a -ζ fixed window, or to make it rotatable around a rotation axis that crosses the center of the window shoji, and to open it to the minimum extent possible to allow ventilation. A rotating window with the shoji fixed in one position, or a casement window with the shoji opened on one side and opened outward, and then fixed in the same minimum open position as above. It is currently installed. However, with this type of window, if it is a fixed window, it is not possible to even ventilate the room, and if it is a revolving window, when the shoji is opened, the opening of the shoji's room p" 2. The windows protrude into the room, creating an obstruction to the indoor space and looking unsightly.Furthermore, in the case of any of the windows mentioned above, for example, in the event of a fire occurring inside a building, fire and rescue personnel will be able to detect people inside the room. L7 was unable to open the window shoji when trying to infiltrate through the window from outside in order to rescue the victim.For this reason, the conventional method was to break the window glass to gain emergency entry into the room, but the thick glass made it difficult to get into the room easily. This was a serious inconvenience because it did not break, and even if it did break, there was a risk of injury to the body due to the fragments and attached pieces when entering the room.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a high-rise window device that allows the window sash to be easily opened from outside in the event of an emergency break-in into a room, such as in the event of a fire outbreak. .

The gist of the present invention in accordance with this object is as follows: ``A window shoji is attached to a window frame in an outward-opening manner, and a first tension bar means is provided between the window shoji and the window frame for restricting the shoji to a first open position. A second stopper means for restricting the window shoji to a second open position having a greater degree of opening than the first open position is provided, and the restriction on the first open position by the first step means is removed from the window shoji. J is provided with a means that can be operated from outside the room.

Next, embodiments of the present invention will be described based on the drawings.

FIGS. 1 and 2 show a front view and a cross-sectional view of a large window device installed, for example, on the third floor or higher of a high-rise residential building, as viewed from the indoor side. In these figures, 1 indicates the upper and lower horizontal frames 2,
3 and left and right vertical frames 4 and 5, a window sash 6 is attached to this window frame 1 in an outward-opening manner. That is, this window shoji 6 is made by fitting a glass plate 11 into a shoji frame consisting of upper and lower horizontal frames 7, 8 and left and right phasing 9, 10, each made of extruded hollow aluminum material.
A phaser 10 (as seen from the indoor side) is pivotally attached to the vertical frame 5 of the window frame 1 by a hinge 12 so that it can be opened only to the outdoor side, and between the window shoji 6 and the window frame 1. The first stopper means 13 limits the opening of the window shoji 6 to a minimum opening position for ventilation (a first opening position) A, and the first stopper means 13 limits the opening of the window shoji 6 to a minimum opening position (first opening position) A for ventilation, and a first stopper means 13 which limits opening of the window shoji 6 to a minimum opening position (a first opening position) A, A second stopper means 14 is provided to restrict the window shoji 6 to an open position (second open position) B that allows intrusion.
Since it is necessary to release the restriction to the first open position by the stopper means 13, the window sash 6 is provided with a release means for this purpose which can be operated from the outside of the room.

To explain the above structure in more detail, first, the first stopper means 13, as is clear from FIGS. 2 and 5,
One end of the link 15 is pivotally connected to the open end side phasing 9 of the window shoji 6 by a shaft 16, and the other end of the link 15 is connected to the window frame 1.
is slidably engaged with the guide groove 17a of the guide member 17 attached to the lower horizontal frame 3 in parallel with the lower horizontal frame 3 via the pin 18,
In addition, one end of the link 19 is attached to the center of the link 15 through the bottle 2.
0, and the other end of this link 19 is pivotally connected with a pin 22 to a mounting part 21 attached to the end of the lower horizontal frame 3, forming a link mechanism. When the is closed, the links 15, 19 are positioned almost parallel to the guide member 17, and when the window shoji 6 is pushed open toward the outdoor side from this position, the bin 18 slides along the guide mL1a toward the vertical frame 4 side. At the same time, the links 15 and 19 swing and protrude toward the outside of the room and are fixed at the position shown by the solid line in FIG. 1, thereby restricting the opening of the window sash 6 to the first opening position A. As is clear from FIGS. 5 and 6, the shaft rod 16 of the link mechanism constituting the first stopper means 13 is a hollow cylinder arranged vertically at the lower end of the shoji phasing 9. The link 15 is fitted into the shaft hole 15a of the link 15 while being supported by the shaped support member 23 so as to be slidable in the vertical direction. This cylindrical support member 23 has a cutout WJ24 extending in the axial direction from the upper end to the middle part, and a support piece 16a integrally provided at a required middle part of the shaft rod 16 can slide into this cutout groove 24. At the same time, under normal conditions, the support piece 16a is locked to the lower end of the notched groove 24 with the lower end of the shaft rod 1G projectingly fitted into the shaft hole 15a of the link 15. The shaft rod 16 is also provided with a groove 6b of a predetermined length at its upper end.

As shown in FIG. 2 or 7, the second stopper means 14 stops one end of the link 25 from the upper horizontal frame 2 of the window frame 1.
A pin 26 is pivotally connected to the lower surface side, an operating pin 27 is attached to the other end of the link 25, and this operating pin 27 is attached to the upper surface side of the upper horizontal stile 7 of the window sash 6 in parallel with the horizontal stile. The link 25 is slidably engaged in the guide groove 29 of the guide member 28 which has been closed, thereby forming a link mechanism. As the window shoji 6 is opened from the closed position, the link 25 swings clockwise with respect to the figure, and is in the first open position A as indicated by the solid line in the figure. When the state shown in FIG. 1 is reached, and furthermore, the restriction of the first opening position A is canceled by the action of a restriction releasing means to be described later, as the window sash 6 is further opened toward the outside from this first opening position A, the link 25 is opened. swings clockwise, and the operating pin 27 slides along the guide groove 29. When the operating pin 27 reaches the right end of the guide groove 29, the opening of the window sash 6 is restricted to 11, and this limit is reached. This position becomes the second open position B.

Next, a means for canceling the restriction on the first open position A will be explained. First, as shown in FIGS. 1, 3, and 4, a flexible long strip-shaped actuator is applied over the inside of the shoji open end side phasing 9 of the window shoji 6 and the inside of the upper horizontal stile 7. The bar 30 is connected to the guide grooves inside these phasing 9 and the upper stile 7 (only the guide groove inside the phasing 9 is shown as 31 in FIG. 3, and the guide groove on the side of the upper horizontal stile 7 is omitted) They are inserted and supported so as to be slidable in the longitudinal direction along the phasing shaft 9, and a pair of inside/outside operation handles 32A, 32B protruding from both the interior and exterior sides of the phaser 9 is rotatably mounted on a shaft at a relatively lower portion of the phaser 9. The rotation axis 33A of these handles 32A, 32B is supported.

33B is a binion 34A, 34B and a rack 35A,
35B to the lifting pieces 36A and 36B, thereby converting the rotational movement of the handles 32A and 32B into vertical linear movement, and the indoor side lifting piece 36A has a substantially C-shaped cross section. The other end of the connecting piece 37A is fixed to the operating bar 30, and the outdoor elevation piece 36B is a flat connecting piece 37B fixed to the operating bar 30. Furthermore, a 1ilJ limit release operating lever 38 is provided on the outdoor side of the phaser 9 so as to be slidable in the lateral direction, that is, parallel to the shoji surface. The outdoor lifting piece 36B is engaged in the stroke limiting slot 39. This elevating stroke limiting slot 39 is for switching the upper limit position of the stroke of the elevating piece into two stages, a first slot portion 39a for a low position and a second slot portion for a high position, which are formed in communication with each other. 39b, and is normally located in the position where the elevating piece 36B is inserted into the first slot portion 39a as shown in FIG. By pulling the lever 38, the lever 38 slides and the engaging position of the lifting piece 36B is in the second slot portion 39b.
It will be switched to. On the other hand, as shown in FIGS. 5 and 6, a shaft lever lifting piece 40 is protruded from the lower end of the operating bar 30, and this lifting piece 40 engages in the slot 16b at the upper end of the shaft rod 16. has been done. The length of this slot H6b in the vertical direction is almost the same as the length of the first slot portion 39H in the vertical direction.
6B is a device that ascends and descends within the slot 16b and the first slot portion 39a (see FIG. 5);
As shown in the figure, when the operating handles 32A, 32B are in the vertical and downward position, the elevating piece 36A.

32B are in the lowest position, and when either the operating handle 32A or 32B is rotated 90° clockwise as indicated by the arrow in the figure, the pinion 34A
, 34B and racks 35A and 35B lift the lifting piece 36A.
, 36B rise to a position corresponding to the upper limit position of the first slot portion 39a, and thereby the connecting pieces 37A, 3
The actuating bar 30 is connected to the lifting piece 36A via 7B.

It rises by the amount of rise of 36B, and at the same time, the shaft lever lifting piece 4
0 only rises to the upper limit position of the slot 16b of the shaft rod 16, which is held in a fixed position, as shown by the imaginary line in FIG. 5, and does not exert any pulling force on the shaft rod 16. In addition, when the outdoor lifting piece 36B is engaged with the first slot portion 39a as described above, that is, when the restriction release operation lever 38 is not activated, the operation handles 32A and 32B are rotated beyond the above-mentioned 90° rotation position. However, by pulling the restriction release operation lever 38 in the direction of the arrow in FIG. 4 and switching the engagement position of the outdoor side lifting piece 36B to the second slot portion 39b, the operation handles 32A, 32B can be moved further by 9
0°, that is, it can be rotated up to 180° clockwise in the figure from the vertical downward position in FIG. Therefore, if one of the operating handles 32A, 32B is rotated from this state, the outdoor lifting piece 36B will rise toward the upper limit position of the second slot portion 39b, and the indoor lifting piece 36A will also rise to the same position. , whereby the operating bar 30 rises and the shaft lever lifting piece 40 lifts the shaft rod 16.
is pulled up and detached from the shaft hole 15a of the link 15 as shown in FIG.
This means that it can be opened beyond the first open position A to the second open position B. When installing the restriction release operation lever 38, for example, as shown in FIG. The engagement protrusion member 42 protruding from the outdoor side surface of the phaser 9 may be engaged so as to be slidable in the lateral direction. In addition, in FIGS. 3 and 4, 43A and 43B are operating handles 32A,
32B's rotating shafts 33A, 33B are supported via bearings (not shown), and pinions 34A, 34B and rank 35Δ
, 35B, and is attached to both indoor and outdoor sides of the shoji phasing 9 with screws not shown.

The lever 38 is slidably sandwiched between the casing 43B and the outer surface of the phase shifter 9.

Furthermore, the means for locking the window sash 6 in the first open position A will be explained with reference to FIGS. 1, 2, and 7.
This locking means includes an operating pin 27 provided at the end of the link 25 and sliding along a guide groove 29 of the guide member 28, and a predetermined locking pin 27 on the guide groove 29 corresponding to the first open position A of the window sash 6. A lock hole 44 having a diameter larger than the groove width of the 1j529 and communicating with the groove 29 is provided at the position.
As shown in FIG.
7a and a small diameter portion 27b which is coaxially connected to the guide groove 29 and slidably engages with the guide groove 29 during normal operation.
7b, a sliding plate 45 is inserted through the lower surface side of the guide member 28, and the operating pin 27 is always held downward between this sliding plate 45 and a fixed plate 46 fixed to the lower end of the small diameter portion 27b. A coil spring 47 is interposed for pressing and biasing. Therefore, when the window shoji 6 is in an open position other than the first open position A, the small diameter portion 27b of the operating pin 27 engages with the guide groove 29 and is slidable, but the window shoji 6 is in the first open position. When the actuating pin 27 reaches the position and matches the large diameter lock hole 44, the actuating pin 27 is pushed down by the biasing force of the coil spring 47, and the large diameter portion 27a of the actuating pin 27 is pushed down as shown by the imaginary line in FIG. It fits into the lock hole 44, thereby restricting the sliding of the operating pin 27, and the window sash 6 is locked at the first open position A. In addition, in order to release the lock at the first open position A, as shown in FIG. A slide bar 48 is connected to the slide bar 48, and this slide bar 48 is slidably arranged on the upper surface side of the upper horizontal stile 7. An unlocking bulge 49 is formed at a position where it slides through the actuating bar 30 and comes directly below the lock hole 44, and when unlocking the first open position A, the handle 32A or 32B is removed. By the rotation operation, this bulging portion 49 is moved to the lower end position of the operating pin 27 which is fitted into the lock hole 44 and pressed down, thereby pushing up the operating pin 27 against the coil spring 47 and increasing the diameter. By letting the portion 27a escape from the lock hole 44 and rotating the window sash 6 either indoors or outdoors from this state, the small diameter portion 27b engages in the guide groove 29 and is moved to the first open position A. The lock will be released.

Furthermore, in order to lock the window shoji 6 in the closed state, as shown in FIGS. 5 and 6, a stopper piece 50 is provided on the inner surface of the vertical frame 4 of the window frame 1 at a position closer to the outdoor side. When the operating handles 32A, 32B are in their original positions and the operating bar 30 is in its lowest position as shown in FIG. The stopper piece 50 is brought into contact with the stopper piece 50, thereby closing and fixing the window shoji 6.

When opening the window shoji 6, the operating handle 3
By rotating 2A or 32B in a predetermined direction, for example, by 90'', the actuating bar 30 rises and the shaft lever lifting piece 40 moves upward and away from the stopper piece 50 as shown by the imaginary line in FIG. If the window shoji 6 is pushed open slightly toward the outdoor side from this state, it will not be locked even if the handles 32A and 32B are returned to their original positions, and the door can be opened to the outdoor side.

The configuration and operation of each part of the window device have been explained in detail above, but to further explain the overall operation of this window device, first, when the window shoji 6 is closed, As shown, the operating handles 32A and 32B are in a vertically downward position, and the operating bar 30 is pulled down to the lowest position.
The shaft lever lifting piece 40 hits the stopper piece 50 and the window shoji 6
is locked, and the restriction release operation lever 38 is shown in FIG.
It is in the position shown in FIG. In order to open the window shoji 6 for ventilation in such a state, turn the operating handle 32A from the indoor side 90 degrees counterclockwise in Fig. 1 and clockwise in Fig. 4 and hold it in that state. When the window shoji 6 is pushed toward the outdoor side, the lock by the stopper piece 50 is released.
The window shoji 6 can be opened, but opening is restricted to the first opening position 8 by the first stomper means 13. This first
When the operating handle 32A is returned to its original position at the open position A, the large diameter portion 27a of the operating pin 27 fits into the long hole 44, and the window sash 6 is fixed at the first open position A. Next, to close the window shoji 6 to stop ventilation, rotate the operating handle 32A by 90 degrees as above and pull it into the room, return the handle 32A to its original position at the window closing position, and the window will open. The shoji 6 is locked in its closed position.

If a fire breaks out indoors and fire and rescue personnel have to enter the room through the window, the window shoji 6 will not open for ventilation even if the operating handle 32B is turned and pulled from outside the room. The operating handle 32B can be rotated up to 180° from the initial position by pulling the restriction release operating lever 38 in the direction of the arrow in FIG.
Therefore, when this handle 32B is rotated 180 degrees clockwise with respect to FIG. 4, the shaft rod 16 is pulled up by the shaft lever lifting piece 40 as shown in FIG. , the restriction by the first stopper means 13 is released, and the handle 3 is removed.
If the 180° rotation state of 2B is pulled, the window shoji 6 will be opened to the second open position B where emergency access is possible.

As explained above, in the high-rise window device of the present invention, since the window shoji is attached to the window frame in an outward-opening manner, it is possible to ventilate the room, and when the shoji is opened, it does not work like a conventional revolving window. There is no inconvenience such as a part of the shoji sliding into the room.

A first stopper means for restricting the shoji to a first open position and a second stopper means for restricting the shoji to a second open position having a greater degree of opening than the first open position are provided between the window shoji and the window frame. 7 bar means, and the window shoji is provided with a means operable from the outside of the room to release the restriction on the first open position by the first stopper means, so that ventilation can be performed at the first open position. By setting the opening position to a relatively small degree and setting the second opening position at least to a degree that allows a person to enter, the device cannot be opened further than the first opening device under normal circumstances, so it is safe. Ventilation can be carried out, and when it is necessary to enter the room from outside the window in the event of a fire or the like, the restriction on the first open position by the first stopper means can be easily released outdoors, and the window shoji can be destroyed. It is possible to enter the room without doing anything.
