Description

The present invention relates to a sliding sash with extended security and ventilation.

In general, for large windows facing the balcony in a house, a glass shoji is attached to multiple sashes with an airtight material, and each sash is attached so that it can be slid. Screen doors are often attached to the outside of such sliding windows and sliding sashes. When it is desired to allow air to pass through, it is common to place a screen door in the open area of the sliding sash to prevent the invasion of pests and open it.

However, when trying to pass air through such a sliding sash, it cannot be opened unless the locking device of the sliding sash is released. For this reason, it may not be possible to easily open the sliding sash for reasons such as crime prevention. In addition, if the entire surface is opened on a rainy day, raindrops may enter the room with the wind.

On the other hand, a sliding window having a form as described in Patent Document 1 has been proposed. A middle rail is passed below one of the sashes, and another shoji mounting frame is provided below the middle rail, and the lower sash is swingably attached to the lower part of the sash. As a result, while the locking device of the sliding sash itself is closed, the portion below the center rail can be tilted inward and independently opened as a window. If the height below the center rail is made smaller, humans cannot pass through and security can be ensured, and since it is an inward-looking window, raindrops will not enter the room unless it is in a very strong wind.

Japanese Unexamined Patent Publication No. 2003-90181

However, in the structure of Patent Document 1, even if the inwardly tilted window is opened, the inner and outer sashes can be freely moved unless the locking device is hung on the sliding window, which is the entire configuration, so that the sash is locked. If the window is left open, so to speak, the sliding window itself may be opened and intruded.

In addition, even if the window is tilted inward, if it is located below and opened wide, there is a possibility that rainwater may enter through the gap depending on the wind direction.

Therefore, an object of the present invention is to provide a structure capable of ensuring a certain level of crime prevention without conscious locking while ensuring the air permeability of the sliding sash.

According to the present invention, a center rail is provided between the left and right stiles constituting the frame of the sliding sash, and a protruding window capable of protruding to the outdoor side is provided on the upper side or the lower side of the center rail. The problem was solved.

When a part of the shoji sticks out to the outside, the protruding window acts as a stopper while the protruding window is open, and it cannot be opened as a sliding sash. As a result, even if the locking device of the sliding sash itself is forgotten to be closed, the sliding sash cannot be opened unless the protruding window is stored in the shoji screen, and the person trying to invade immediately invades. It is not possible. As a result, a certain level of crime prevention can be ensured even if the locking device is not applied.

Further, when the installation position of the protruding window is set to be on the upper side of the center rail, the center rail may be passed at a position above the center. By arranging the center rail above the center of the sash, the weight of the protruding window that rides on it is reduced, and it becomes easier to support the weight with the center rail passed between the left and right stiles, giving you more freedom in sash design. improves.

As a result, even if a protruding window including a center rail is attached to an existing sash as an attachment, the structure becomes stable. In addition, since the protruding window is located above the window or door, the possibility of raindrops entering even if the wind enters can be almost eliminated.

When the internal sliding door of the existing sliding sash has a general structure in which a glass plate can be fixed to the upper, lower, left and right stiles via a resin material, the present invention has the following structure. realizable. The protruding window is a general one having an outer frame to be fixed, an inner frame that holds a glass plate and is tilted to the indoor side, and an arm that connects the outer frame and the inner frame. The left and right and upper outer frames of the outer frame are fitted into the glass holding portion of the inner sash, the middle rail is the lower outer frame, and the lower surface of the middle rail is the glass on the lower side of the inner sash. The glass plate that covers the surface below the center rail is provided so as to have a glass plate holding portion that can be fixed to the holding portion.

As a form for opening and closing the protruding window that can be attached to the existing sliding sash in this way, the arms provided on the left and right stiles of the inner frame, the protruding rods provided on the lower stile of the inner frame, and the like can be used to open the windows. It can be achieved by supporting the protruding window in the state and removing these supports when closing it.

According to the present invention, it is possible to open only the protruding window to ensure ventilation while keeping the internal and external sashes closed, while it is possible to immediately open the sliding sash even when it is unlocked. However, the protruding window cannot be opened unless it is stored in the shoji screen, and it can also exert temporary crime prevention.

Further, since the protruding window protrudes to the outside, the possibility of rainwater entering the room can be almost eliminated as compared with the case of using the inward tilting window.

The inner sash 11 and the outer sash 12 are attached so as to be pulled apart from the sash frame 1. In this embodiment, the internal shoji 11 and the external shoji 12 are each composed of one sheet, but an embodiment composed of two sheets each may be used. The sash frame 1 is rectangular with an upper frame 1a and a lower frame 1b having rails 2 for guiding the movement of the inner sash 11 and the outer sash 12, and left and right vertical frames 1c and 1c where the inner sash 11 and the outer sash 12 abut. It is configured in shape.

The internal shoji 11 connects the upper stile 11a, the lower stile 11b, the merging stile 11c, and the door tip stile 11d in a rectangular shape. In the upper part of the frame of the inner sash 11, a middle stile 13 is provided in contact with the upper stile 11a and extends between the left and right stiles 11c and the door end stile 11d. A large window glass 19 is fitted on the top. On the other hand, a protruding window 14 is provided below the center rail 13. In the protruding window 14, an inner frame 16 provided with a small window glass 18 is rotatably attached to an outer frame 15 fixed to the inner sash 11, and the inner frame 16 is rotated to the outdoor side. By tilting the windows, the windows can be opened and closed independently of the sliding arrangement of the internal sash 11 and the external sash 12.

Both the outer frame 15 and the inner frame 16 of the protruding window 14 have a rectangular shape. Is the upper frame 15a of the outer frame 15 of the protruding window 14 in contact with the center rail 13 that passes between the sash 11c of the shoji 11 and the door end stile 11d and fixes the large window glass 19 from above? , Or is integrated with the center rail 13. In this embodiment, an example is shown in which the middle rail 13 is integrated with the upper frame 15a which is the upper side of the outer frame 15. Further, in this example, the lower frame 15b and the lower stile 11b on the lower side of the outer frame 15 are integrated, and the vertical frames 15c and 15d on the left and right of the outer frame 15 are the combined stile 11c and the door tip stile 11d. It is integrated.

The large window glass 19 attached above the middle rail 13 (upper frame 15a of the outer frame 15) passed to the middle of the inner sash 11 has the upper stile 11a, the merging stile 11c, and the door end of the inner sash 11. It is surrounded by a stile 11d and a center rail 13, and is fitted into a glass holding portion 28 extending toward an inner opening thereof and fixed with a resin material 29.

FIG. 3 shows an enlarged vertical cross-sectional view of each of the frames 11a to 11d, and the outer frame 15 and inner frame 16 of the protruding window 14, and FIG. 4 shows a horizontal cross-sectional view. The upper, lower, left and right stiles (11a to 11d, 12a to 12d) of the inner sash 11 and the outer sash 12 are provided with two projecting plates 41a and 41a extending toward the center of the sash. The tips of the protruding plates 41a and 41a are folded back so as to narrow the distance between them to form the glass pressing portions 41c and 41c. A resin material 42 is introduced between the glass pressing portions 41c and 41c, and the glass plate can be fixed via the resin material 42. In the outer sash 12, as shown in FIG. 3, a large window glass 19 which is a glass plate covering the upper and lower parts of the opening of the outer sash 12 with the middle rail 17 sandwiched between the glass holding portions 41c and 41c is sandwiched and fixed. ing.

On the other hand, in the inner sash 11, a large window glass 19 is attached above the middle rail 13 with the same structure as the outer sash 12. Below the middle rail 13, the outer frame 15 (15a to 15d) protruding toward the center on the indoor side in the middle rail 13, the lower stile 11b, and the lower portion of the merging stile 11c and the door end stile 11d. )have. In each case, the inner frame 16 is in contact with the inner frame 16 at one or two places, and each contacting portion is provided with a door contact portion 20 provided facing the outdoor side, and the inner frame 16 swings from the outdoor side. Touch this. In FIG. 3, only the lower frame 15b on the lower side is in contact with the lower frame 16b of the inner frame 16 at one place, but the structure may be in contact with the lower frame 16b at two places.

The left-right width of the outer edge of the inner frame 16 is larger than the left-right width of the inner edge of the outer frame 15, and the inner frame 16 can be sealed when the inner frame 16 is attached to the outer frame 15. Further, a hook-shaped portion 21 having a hook-shaped tip is provided at the tip of the upper frame 16a of the inner frame 16 so that the tip can be hooked. The inside of the bent hook-shaped portion 21 has a peripheral surface. A shaft receiving portion 22 having a peripheral surface is provided on the outdoor side of the upper frame 15a of the outer frame 15 so as to face the hook-shaped portion 21. With the shaft receiving portion 22 as a rotating shaft, the hooked hook-shaped portion 21 rotates halfway, and the entire inner frame 16 of the protruding window 14 is opened to the outdoor side. The situation is shown by the broken line in the figure.

When the protruding window 14 is open, the protruding window 14 itself acts as a stopper for opening the sliding sash 10. As a result, by opening only the protruding window 14 to the extent that human hands cannot enter it, it is possible to maintain an open state in which air permeability is ensured while ensuring crime prevention.

Although not shown, the method of maintaining the protruding window 14 in the partially open state in the present invention is a known mechanism such as an arm or a stopper used to maintain the protruding window 14 in the open state when the general protruding window 14 is used alone. Can be used.

Further, on the inner peripheral side of the inner frame 16, like the inner sash 11 and the outer sash 12, a glass holding portion 28 having a narrow width is provided so that a glass plate (small window glass 18) can be sandwiched and fixed. is there. The small window glass 18 inserted into the glass holding portion 28 is fixed by filling with a resin material 29.

Further, a linkage lock 23 connecting the lower frame 16b of the inner frame 16 of the protruding window 14 and the lower frame 15b of the outer frame 15 is provided to enable opening and closing of the protruding window 14 and prevent excessive opening. It is desirable to do so. This is because it is assumed that the product is left in an open state, and it is desirable that the opening width can be suppressed to the extent that small animals and the like do not invade. A mechanism that can suppress excessive opening while enabling such opening and closing can be adopted not only as a linkage lock, but the linkage lock is easy to handle because it is attached to an internal shoji.

Further, although not shown, it is preferable to provide a locking device between the lower frame 15b of the outer frame 15 and the lower frame 16b of the inner frame 16. As the structure of the locking device, the one used for a general protruding window can be adopted.

Yet another embodiment is shown in FIGS. 5 and 6. Electromagnetic locks 24a and 24b are provided in place of the linkage lock 23 on the lower frame 16b of the inner frame 16 of the projecting window 14 and the lower frame 15b of the outer frame 15, respectively. The form is not particularly limited, but for example, the electromagnetic lock 24a is a permanent magnet, and the electromagnetic lock 24b is provided with an electromagnet. In response to the input from the electric signal, the magnetic force of the electromagnetic lock 24b is released so that the lock can be unlocked.

In this embodiment of unlocking by an electromagnetic lock, if an urging device that automatically opens the protruding window 14 when the electromagnetic lock is unlocked is attached, the protruding window 14 is opened by remote control or automatic operation. It is more desirable because it can be done. In the embodiment of the urging device shown in FIG. 5, the projecting device 25 is attached to the vertical frames 15c and d of the outer frame 15, and the tip of the projecting rod projected by the elastic body contained in the projecting device 25 is the vertical frame of the inner frame 16. Attached to 16c and 16d. This protruding force is weaker than the fixing force of the electromagnetic locks 24a and 24b, and the protruding window 14 is not opened when the electromagnetic lock is locked. Further, once the window is opened, the protruding window 14 can be manually pulled in and locked to return to the original state.

The conditions for unlocking the electromagnetic locks 24a and 24b include, for example, a timer setting for unlocking at a specific time of the day, and a stage where the room temperature obtained by the temperature sensor installed in the room exceeds the threshold value. The temperature control that unlocks with is mentioned. Not limited to these, it is desirable to unlock the electromagnetic locks 24a and 24b when a predetermined condition is satisfied so that the protruding window 14 can be automatically opened.

Further, it is more desirable to detect the open state of the sliding sash 10 and not unlock the sliding sash 10 itself in the open state because wasteful locking work can be saved. Furthermore, when the electromagnetic locks 24a and 24b are connected to a home router and an instruction for remote control via the Internet is received, the resident can automatically unlock the lock by satisfying the above-mentioned predetermined conditions. The protruding window 14 may be opened.

When the protruding window 14 is opened, the sliding sash 10 according to the present invention cannot be opened because the protruding window 14 acts as a stopper. For this reason, even if it is automatically opened by an instruction from a remote location, or if it is automatically opened by satisfying a predetermined condition when there are no people in the building, it is ventilated while maintaining a certain level of crime prevention. Can be made possible.
