Description

[0001]
[Industrial applications]
The sliding window device with the opening device of the present invention is used, for example, as a smoke exhaust window or a ventilation window.
[0002]
[Prior art]
In the event of a fire in a room, to exhaust the smoke filling the room to the outside, or to discharge the indoor air to the outside when the room air is stagnant, instead introduce the outdoor air to the room. For this purpose, various window devices have been conventionally used. Further, a damper having elasticity in the extension direction is incorporated in the window device used in such a portion, and the window sash is swung in the opening direction by the damper. That is, when the lock is released in order to exhaust smoke or ventilate, the window shoji swings in the opening direction due to the elasticity of the damper without particularly putting a hand on the window shoji.
[0003]
FIG. 9 shows a window device with an opening device that has been widely used in the past for such a purpose. Inside a rectangular window frame 1 composed of an upper frame, a lower frame, and left and right vertical frames, a window shoji 2 that surrounds four sides of a rectangular panel with an upper frame, a lower frame, and left and right vertical frames is placed on the upper frame. Is built by pivoting on the upper frame. Further, a damper 3 called a stay damper having elasticity in the extension direction is provided between the vertical frame and the vertical frame.
[0004]
In the case of such a window device with an opening device, the window shoji 2 is normally held inside the window frame 1 by a locking device provided between the lower frame and the lower frame during normal times. On the other hand, when smoke or ventilation is performed, the locking device is unlocked. As a result, the window shoji 2 is pushed out of the window frame 1 by the elasticity of the damper 3. When closing the opened window sash 2 again, the window sash 2 is pulled manually or by a separately provided closing cable against the elasticity of the damper 3 until the locking device is operated.
[0005]
[Problems to be solved by the invention]
The window device with the opening device as shown in FIG. 9 has the following points to be solved.
(1) The efficiency of smoke emission and ventilation is not good. That is, in order to efficiently perform smoke exhaust and ventilation, it is preferable to provide an opening device in the sliding window that pushes the entire window shoji out of the window frame, but in the case of the structure shown in FIG. Since the upper end of 2 is still connected to the window frame 1, the efficiency of smoke exhaust and ventilation is not good.
{Circle around (2)} When the window shoji 2 becomes large, a large damper 3 must be used in accordance with the weight of the window shoji 2, but in the case of the structure shown in FIG. It must be installed in the gap between the inside of the frame and the outside of the vertical frame. For this reason, as the outer diameter of the damper 3 increases, the width dimension (found width) of the vertical frame and the vertical frame increases accordingly, and the design of the window device deteriorates.
{Circle around (3)} Since the pressing force of the damper 3 is directly transmitted to the vertical frame, if the elasticity of the damper 3 is increased, the window shoji 2 may drop (change in shape) based on the elasticity. . Then, there is a possibility that the lower frame of the window shoji 2 and the lower frame constituting the window frame 1 collide, and the window device cannot be closed.
(4) Since the swing angle of the window shoji 2 is not particularly increased with respect to the amount of extension of the damper 3, in order to open the window shoji 2 sufficiently large, a damper 2 having a sufficiently large stroke is used. Must.
The sliding window device with the opening device according to the present invention is designed to solve all of the problems (1) to (4).
[0006]
[Means for Solving the Problems]
The sliding window device with an opening device according to the present invention comprises a rectangular window frame composed of an upper frame, a lower frame, and left and right vertical frames, and four rounds of a rectangular panel surrounded by an upper frame, a lower frame, and left and right vertical frames. A pair of left and right link devices, each comprising a window shoji and a plurality of link arms and provided between the inner surface of the left and right vertical frames and the outer surface of the left and right vertical frames, A damper which has elasticity and pushes the window sash out of the window frame as it is extended.
[0007]
Each of the link devices has a slider and first to third link arms. The slider is supported on the inner surface of each of the vertical frames so as to be able to move up and down. For this purpose, for example, an engaging groove is formed on the inner surface of each of the vertical frames, or a guide bracket having an engaging groove on the inner surface is fixed, and the slider can slide only in these engaging grooves. To engage.
[0008]
On the other hand, one end of each first link arm among the first to third link arms provided on each side of the window shoji is supported by the slider. The other end of each of the first link arms is pivotally supported at one end of each of the vertical frames. Each of the second link arms is arranged substantially parallel to the first link arm. One end of each of the second link arms is pivotally supported on the inner surface of the intermediate portion of each of the vertical frames. The other end of each of the second link arms is pivotally supported on the outer surface of the intermediate portion of each of the vertical frames.
[0009]
One end of each third link arm is pivotally supported at an intermediate portion of each of the second link arms. The other ends of the third link arms are pivotally supported by the sliders. Each of the third link arms is provided substantially parallel to a straight line connecting the shafts pivotally supporting the other ends of the first and second link arms. Therefore, a part of each of the vertical frames, each of the first link arms, a part of each of the second link arms, and each of the third link arms constitute a deformable link structure.
[0010]
A fourth link arm is added to at least one of the pair of left and right link devices, each of which is constituted by the first to third link arms. Then, one end of the fourth link arm is pivotally supported at an intermediate portion of at least one of the pair of second link arms. Further, the damper is displaced from a position where the slider moves up and down to a side opposite to a side on which the window shroud is extruded when the window device is opened, and is opened and closed by the window frame along the vertical frame. It is fixed without swinging . The other end of the fourth link arm is pivotally supported at the displacement side end of the damper.
[0011]
[Action]
The operation of the sliding window device with the opening device of the present invention configured as described above is as follows. First, in order to close the window opening, when the window shoji is pulled inside the window frame, a part of each vertical frame, each first link arm, a part of each second link arm, and each third link arm Means that the deformable link structure is crushed and the window shoji is allowed to enter the inside of the window frame. Further, the other end of the fourth link arm pushes the damper, and the entire length of the damper is elastically reduced. In this state, for example, if the locking device provided between the lower frame and the lower frame is operated (locked), the window opening can be kept closed regardless of the elasticity of the damper.
[0012]
Next, when opening the window opening, for example, the locking device is released. As a result, the fourth link arm pushes the second link arm by the elasticity of the damper in the extending direction, and swings each second link arm around one end thereof. As a result, the slider slides along the vertical frame, and the first and third link arms that pivotally support one end or the other end of the slider swing about the slider-side end. As described above, the parallelogram link structure is opened as the first to third link arms swing. In this state, the entire window sash slides out of the window frame, and a gap is created between the upper and lower ends of the window sash and the window frame.
[0013]
【Example】
1 to 7 show a first embodiment of the present invention. FIG. 1 shows the entire configuration of a sliding window device with an opening device according to the present invention in a state where a window shoji 2 is projected (slid out) from the inside of a window frame 1 to the outdoor side. The window frame 1 is formed in a rectangular shape by combining an upper frame 4, a lower frame 5, and left and right vertical frames 6, 6 each made of an extruded aluminum material. The window sash 2 is formed by an upper frame 7, a lower frame 8 and left and right vertical frames 9, 9 each of which is made of an extruded aluminum material. It is constituted by surrounding.
[0014]
Between the inner surface of each of the vertical frames 6 and 6 constituting the window frame 1 and the outer surface of each of the vertical frames 9 and 9 constituting the window shoji 2, each was constituted by a plurality of link arms. , A pair of left and right link devices 11 is provided. A damper 12 having elasticity in the extension direction is provided between one or both of the pair of link devices 11 and the inner surface of the upper end of the vertical frame 6 facing the link device 11. , Are provided as shown in FIGS. The window shoji 2 is pushed out of the window frame 1 by the action of the pair of link devices 11 as the damper 12 extends.
[0015]
Each of the link devices 11 has a slider 13 and first to third link arms 14 to 16, as shown in FIG. The slider 13 is made of a slippery synthetic resin such as polyamide resin, and is supported on the inner surfaces of the vertical frames 6 so as to be able to move up and down. For this purpose, in the illustrated embodiment, a guide bracket 18 having an engaging groove 17 is fixed to the inner surface of each of the vertical frames 9 and 9. The guide bracket 18 is formed by, for example, extrusion molding of an aluminum material, and has a dovetail-shaped engaging groove 17 in which the width of the opening on the inner surface side is narrow and the width of the back is wide. The slider 13 is engaged with the engaging groove 17 so as to freely slide only in the vertical direction.
[0016]
On the other hand, one end (lower end) of each first link arm 14 among the first to third link arms 14 to 16 constituting each link device 11 is pivotally supported by each slider 13. The other end (upper end) of each of the first link arms 14 is pivotally connected to one end (upper end) of each of the vertical frames 9, 9 so as to be swingably displaceable by a shaft. For this reason, in the illustrated embodiment, a displacement-side pivot bracket 19 is fixed to the upper outer surface of each of the vertical frames 9. The displacement-side pivot bracket 19 is made of a plate material having sufficient rigidity, such as a steel plate, and is fixed to the upper outer surface of each of the vertical frames 9, 9 by screws or the like. The other end of the first link arm 14 is pivotally supported on the upper end of the displacement-side pivot bracket 19.
[0017]
Each second link arm 15 is arranged in parallel with each of the first link arms 14. One end (lower end) of each of the second link arms 15 is pivotally supported on the inner surface of the intermediate portion of each of the vertical frames 6. In the illustrated embodiment, a fixed-side pivot bracket 20 is fixed to the lower end of each of the guide brackets 18, and one end of each of the second link arms 15 is pivotally supported by the fixed-side pivot bracket 20. ing. The other end (upper end) of each of the second link arms 15 is pivotally supported on the outer surface of the intermediate portion of each of the vertical frames 9. In the illustrated embodiment, the other end of each of the second link arms 15 is pivotally supported at the lower part of the displacement-side pivot bracket 19.
[0018]
One end (lower end) of each third link arm 16 is pivotally supported at an intermediate portion of each second link arm 15. The other ends (upper ends) of the third link arms 16 are pivotally supported by the sliders 13, respectively. Each of the third link arms 16 is a straight line connecting the axes that pivotally support the other ends of the first and second link arms 14 and 15 (in the illustrated embodiment, the displacement-side pivot bracket 19). Are provided in parallel to Accordingly, the displacement-side pivot bracket 19, which is a part of each of the vertical frames 9, 9, the first link arm 14, a part of the second link arm 15, and the third The link arm 16 forms a deformable substantially quadrilateral link structure.
[0019]
Incidentally, in the case of the first embodiment shown in FIGS. 1 to 7, one end of each first link arm 14 and the other end of each third link arm 16 are located at two positions above and below each slider 13. And pivot independently of each other. However, one end and the other end of these link arms 14 and 16 pivotally support the slider 13 at one location (by one pivot) as in the second embodiment shown in FIG. May be configured. In any case, the displacement-side pivot bracket 19, the first link arms 14, a part of the second link arms 15, and the third link arms 16 are linearly connected. It is necessary to form a substantially quadrilateral or quadrilateral link structure that can be deformed to the extent that it can be folded. To this end, of the pivot center points of the link structure, the total length of the lines connecting the upper and lower two points through the other pivot center points is made equal on any side. For example, in FIG. 2, the total length of two lines connecting points abc is equal to the total length of three lines connecting points adec.
[0020]
A fourth link arm 21 is added to at least one of the pair of left and right link devices 11, each of which is constituted by the first to third link arms 14 to 16. The fourth link arm 21 that constitutes the opening device together with the damper 12 only needs to be provided on at least one of the link devices 11. However, in order to make the force applied to the window shoji 2 from the damper 12 to the left and right uniform, it is preferable to provide one pair of the fourth link arms 21 for each link device 11.
[0021]
One end of such a fourth link arm 21 is located at an intermediate portion between the pair of second link arms 15 and a portion of the second link arm 15 pivotally supporting one end of the third link arm 16. The arm 15 is pivotally supported at a portion (lower side) near one end. Further, the damper 12, which constitutes an opening device together with the fourth link arm 21, is located on a side opposite to a side on which the window shoji 2 is extruded when the window device is opened from a position where the slider 13 moves up and down, that is, the guide bracket. It is fixed to the window frame 1 along the vertical frame 6 so as to be shifted to the indoor side (the right side in FIGS. 2 and 3 and the lower side in FIG. 4) from 18. That is, a fixing bracket 22 made of a plate material having sufficient rigidity such as a steel plate is fixed to the upper end of the vertical frame 6, and the upper end of the cylinder case 23 forming the damper 12 is screwed to the fixing bracket 22. Stopped and fixed. The cylinder case 23 of the damper 12 does not swing with the opening and closing of the window shoji 2. The other end (upper end) of the fourth link arm 21 is pivotally supported by the lower end of a rod 24 which is a displacement side end of the damper 12 and is elastically pushed out of the cylinder case 23.
[0022]
The operation of the sliding window device with the opening device of the present invention configured as described above is as follows. First, when the window shoji 2 is pulled into the window frame 1 to close the window opening, the displacement side pivot bracket 19 fixed to each of the vertical frames 9, 9 and the first link arms 14, A part of each of the second link arms 15 and each of the third link arms 16 have a deformable substantially quadrangular link structure such that the link arms 14, 15, 16 are linearly overlapped. To allow the window shoji 2 to enter the inside of the window frame 1. At this time, one end of the fourth link arm 21 is pushed by the second link arm 15, and the other end of the fourth link arm 21 pushes up the rod 24 constituting the damper 12, thereby reducing the total length of the damper 12. Elastically shrink. In this state, for example, if a locking device provided between the lower frame 5 and the lower frame 8 is operated (locked), the window opening can be kept closed regardless of the elasticity of the damper 12. .
[0023]
Next, when opening the window opening, for example, the locking device is released. As a result, the fourth link arm 21 pushes the second link arm 15 due to the elasticity of the damper 12 in the extension direction. That is, the rod 24 pushes the fourth link arm 21 downward, and the fourth link arm 21 swings each of the second link arms 15 around one end thereof. As a result, the slider 13 slides downward along the guide bracket 18 fixed to the vertical frame 6, and the first and third link arms 14, 16 pivotally supporting one end or the other end of the slider 13 respectively. Swings around the end on the slider 13 side. As described above, as the first to third link arms 14 to 16 swing, the substantially quadrangular link structure is opened. In the illustrated embodiment, the opening of the window shoji 2 (expansion of the quadrilateral link structure) is regulated by the lower end of the slider 13 abutting against the upper end of the stopper plate 25. In this state, the entire window sash 2 slides out of the window frame 1, and a gap is formed between the upper and lower ends of the window sash 2 and the window frame 1.
[0024]
Note that the opening device of the present invention can also be used for a so-called flip-out sliding window whose upper part (gap between the upper frame and the upper frame) is largely opened. In this case, the mounting directions of the respective link arms constituting the link device are upside down (one end is the upper end), and the extending direction of the rod of the damper is upward. In the case of such a structure, the efficiency of smoke exhaust and ventilation can be further improved. The engagement groove 17 for engaging the slider 13 does not necessarily need to be provided in the guide bracket 18 separate from the vertical frame 6. The engagement groove 17 can be formed directly on the vertical frame 6.
[0025]
Further, as the fourth link arm 21, a “「 ”-shaped one bent in the direction in which the lower right part of FIG. 2 protrudes is used, and the other end of the fourth link arm 21 and the third link arm 16 If these interferences are prevented, the link arms 21 and 16 can be arranged closer to each other. Then, even if the stroke of the damper 12 is reduced, the opening degree of the window shoji can be sufficiently ensured.
[0026]
【The invention's effect】
Since the sliding window device with the opening device according to the present invention is constructed and operates as described above, the following excellent effects (1) to (4) can be obtained.
{Circle around (1)} When the window opening is opened, the entire window shoji 2 slides out of the window frame 1, and a gap is formed between the upper and lower ends of the window shoji 2 and the upper and lower ends of the window frame 1. Efficient smoke and ventilation.
{Circle around (2)} Even if the damper for pushing out the window shoji 2 becomes large, it is not necessary to increase the apparent dimensions of the vertical frame and the vertical frame, and the design of the window device can be made simple.
