Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding window in which a ventilation device is provided in the vertical frame of the window frame.

Generally, a rain return wall that stands higher than the rail is installed at the indoor end of the lower frame of a sliding window frame to keep out the rain and to support the sliding door to withstand wind pressure.
Sliding doors must be installed or removed from the window frame from the outside side of the sliding surface.

In conventional sliding windows, the distance between the outer sliding door apertures of the left and right vertical frames is equal to the distance between the inner sliding door apertures, and the sum of the widths of both the inner and outer sliding doors is equal. is larger than the above distance.

Therefore, regardless of whether the inner and outer sliding doors are in the closed or open position, at least a portion thereof overlaps in the indoor-outdoor direction.

Therefore, with conventional sliding windows, if the outer sliding door is still installed, it is impossible to sufficiently protect the left and right ends of the inner sliding door and remove it from the window frame from the indoor side, or install it into the window frame.
First, the outer sliding door must be removed, then the inner sliding door must be removed, and the outer sliding door must be installed after the inner sliding door is installed. It was difficult to work while protecting the outside sliding door from a window on the second floor or above.

The technical concept of providing a ventilation device in the vertical frame of a window frame is already known.

However, conventional ventilation devices have a structure in which the entire vertical frame is formed into a rectangular tube shape, and the holes provided on the outdoor side of the vertical frame and the holes provided on the indoor side are communicated through the hollow part of the vertical frame. there were.

Therefore, there is a drawback that the amount of material consumed for forming the vertical frame increases, resulting in high costs.

Furthermore, as mentioned above, conventional ventilation systems use rectangular cylindrical vertical frames over the entire expected width, so even if a sliding window is equipped with such a ventilation system, the window frame of the sliding door when the window is opened is However, the condition of the above-mentioned building materials did not change at all, and the difficulty of installing and removing sliding doors and the risk of falling did not improve at all.

This invention reduces the amount of material consumed for forming the vertical frame by making only the inner sliding door stop part of the vertical frame of a sliding window protrude inside the window opening and providing a ventilation device in the protruding part. At the same time, by applying creativity to the amount of protrusion of the door stop for the inner sliding door, it is easier to install a ventilation system and improve ventilation efficiency, and it is also possible to construct an outer sliding door with a double sliding window. To make it possible to safely remove and install an inner sliding door from the indoor side while leaving it attached, thereby eliminating the difficulty in installing and removing the sliding door and the risk of it falling.

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

In the window frame F, which is made up of the upper frame 1, the lower frame 2, and the left and right vertical frames 3 and 4, an inner sliding door d1 and an outer sliding door d2 are built using the Kendon method in the same manner as before, and the inner sliding door d1 is slidably held by a guide piece 5 on the upper frame and a rail 6 on the lower frame, and an outer sliding door d2 is held slidably by a guide piece T on the upper frame and a rail 8 on the lower frame.

d3 is a screen door installed as desired, and is movably held by guide pieces 9 on the upper frame and rails 10 on the lower frame.

The illustrated window frame F has a mounting edge 11 provided on the outer periphery of the outdoor side portions of the upper and lower frames 1 and 2 and the left and right vertical frames 3 and 4, respectively, to the outside of the lintel 12, window sill 13, and pillar 14. It is attached in a known manner by abutting against the sides and fastening with nails or screws 15.

The upper frame 1, the lower frame 2, and the left vertical frame 3 have the same structure as the conventional one, and the vertical frame 3 has a base plate 16 and a protruding edge of 17°18. A door stop part 20 for the inner sliding door and a door stop part 21 for the outer sliding door are formed on the inside.

On the other hand, the right vertical frame, that is, both the interior and exterior sliding doors d1. d2
The vertical frame 4 against which the inner sliding door d abuts when it is placed in the window closed position has a novel configuration according to the invention.

That is, when the vertical frame 4 is closed, the inner sliding door door stop portion 22 projects from the base plate 23 of the vertical frame toward the inside of the window opening.

This doorstop part 22 is formed in the shape of a rectangular tube protruding from the base plate 23 in the direction of the vertical frame 3, and has a recess into which the vertical frame 24 of the inner sliding door d1 can be fitted on the surface facing the vertical frame 3 of the pond. It has a groove 25.

Moreover, the door stop part 2B for an external sliding door is formed by the outdoor side wall 26, the base plate 23, and the ridge 21 of the door stop part.

The doorstop 22 is also provided with a ventilation system in accordance with the invention, as shown in FIGS. 3 and 4.

In the illustrated example, the ventilation system is installed on the indoor side wall 2 of the door stop 22.
A ventilation hole 30 is provided in the outdoor side wall 26, and a ventilation hole 31 is provided in the outdoor side wall 26.
The indoor and outdoor areas are communicated through these ventilation holes, and normally the ventilation holes 26 can be opened and closed as necessary by a shielding plate 32 that is vertically slidable.

To install the blocking plate 32, form holding pieces 33a and 33b on the left and right sides of the ventilation hole 30 on the back side of the indoor wall 29, provide fitting grooves 34, 34, and slide the blocking plate up and down into the fitting grooves. They fit together freely.

35 is the handle of the blocking plate, 36 is the holding piece 33 a + 33
This is an airtight material that is fitted into the shield plate b and is in pressure contact with the back surface of the shield plate.

37 is a stopper that locks and holds the blocking plate in the raised position, and is rotatably hinged to the indoor side wall of the door stop, and is supported by the spring 3.
8, it is pressed toward the blocking plate 32.

On the other hand, there are many ventilation holes 3 in the outdoor side wall 23 of the door stop 22.
1, and left and right holding pieces 39a and 39b are integrally molded inside the ventilation holes at both left and right ends to form a fitting groove 40a.
, 40b are provided, and an insect screen 41 is stretched over the fitting groove to prevent insects and dirt from entering the door stop part 22.

With the configuration as described above, when the blocking plate 32 is lifted, the stopper 37 enters above the blocking plate 32 and the blocking plate 3
2 is locked and protected in the raised position, and the ventilation hole 30 is opened to ventilate the room.

The ventilation hole 30 and the ventilation hole group 31 are located at the top and bottom 2 of the vertical frame, respectively.
If installed in a specific location, ventilation efficiency is extremely good.

Further, when the stopper 37 is rotated by the force of the spring 38 to release the lock of the blocking plate 32, the blocking plate descends due to its own weight or by the force applied downward by hand, sealing the ventilation hole 30. and shut off ventilation.

In this way, even if the windows are closed and locked on summer nights, the blocking plate 3
By raising the temperature of 2, indoor ventilation is maintained, so you can spend a cool night. Also, when used in the kitchen, oxygen deficiency can be prevented.

Furthermore, by lowering the shielding plate on rainy and windy days, rain and wind can be prevented from entering the room.

Furthermore, since the doorstop part 22 is provided along the entire length of the vertical frame, it is possible to provide ventilation holes and shielding plates at two locations at different heights, allowing for efficient ventilation in a short time.
It can be easily installed at any height that is easy to operate, and since it is located on the wall side, it does not spoil the appearance of the window.

In the above embodiment, only a natural ventilation device consisting of a ventilation hole and a blocking plate that opens and closes the ventilation hole is provided in the vertical frame. However, due to the increased width of the vertical frame, forced ventilation can be It is obvious that it is also possible to provide a device.

When a ventilation device is provided by protruding the door stop portion 22 from a portion of the vertical frame 4 corresponding to the sliding surface of the inner sliding door, the following effects can be obtained.

That is, since the door stop portion 22 projects from the base plate 23 of the vertical frame toward the inside of the window opening, the lower frame 2 extends below the door stop portion, as clearly shown in FIG. Therefore, if rain enters through the outdoor ventilation hole 31 of the door stop or condensation forms on the inner surface of the door stop, the water can be drained outdoors along the top surface of the bottom frame. Since it is easy to do, there is no need to take special precautions to keep out rain when installing a ventilation device in the vertical frame.

Further, the inner and outer sliding doors d1. When d2 is closed, as shown in FIG. 1, the vertical stile 24 of the inner sliding door d1 fits into the protruding door stop part 22 of the vertical frame 4, and the vertical stile 42 of the outer sliding door d2
fits into the door stop part 21 of the vertical frame 3, so the distance between the door stops for the inner sliding door is 11, and the distance between the door stops for the outer sliding door is 12.
, the sum of the widths of the inner and outer sliding doors is 13, and the combined amount of the inner and outer sliding doors is l.
The previous door.

If the amount of protrusion of the contact portion 22 from the substrate 23 is l, then 12
=11+l・・・・・・(1)13-11+14
...... (2) Therefore, when the inner and outer sliding doors are moved to the open side, let L be the size of the gap created between the two sliding doors, then L-12-13 ......(3).

Therefore, (1) in equation (3)? When formula (2) is substituted, L = 1-14.

That is, the protrusion amount l of the door stop portion 22 is equal to the amount 14.
If it is larger than , L becomes positive.

If the amount of protrusion is increased, it becomes easier to provide a ventilation device in the doorstop, and ventilation efficiency can also be improved.

Also, if L is increased, the inner sliding door d
1 and the outer sliding door d2 can be placed in a state where they do not overlap with each other.

In this way, in this invention, l is set so that l>14, and since 11<12, 13 is set so that the relational expression 11<13<12 holds from equations (1) and (2). At the same time, the amount of protrusion of the door stop portion 22 is adjusted so that when the inner and outer sliding doors are moved to the open side, the distance between the inner sliding door and the outer sliding door, and between the inner sliding door and the vertical frame 3 on the opposite side of the outer sliding door is increased. The setting is such that a gap is formed in which a hand can be inserted to grasp the handle.

As described above, by setting the protrusion amount l of the door stop 22 and the sum 13 of the widths of the inner and outer sliding doors, the inner and outer sliding doors d1.
d2 can be removed from the window frame F in the following manner.

That is, first, as shown in FIG. 5a, the inner and outer sliding doors d1. When d2 is moved as much as possible toward the open side and brought into contact with the window frame F, since 12>13, there is a gap between the inner sliding door d1 and the outer sliding door d2 that is large enough to allow you to insert your hand. arise.

Therefore, as shown in FIG. 5, by slightly moving the inner sliding door d to the right, both left and right ends of the inner sliding door can be grasped with both hands.

In this way, hold both ends of the inner sliding door d, lift the inner sliding door, remove the door roller 43 from the rail 6 and place it on the outer rail 8 from the state shown in b' in the same figure, and place it on the outer rail 8. Since the upper end part is removed from the guide piece 5, the inner sliding door can be folded indoors and removed from the window frame F.

Next, when removing the outer sliding door d2 from the window frame F, since the inner sliding door d has already been removed, as shown in FIG. can be easily held with both hands.

Then, lift the outer sliding door d2 by holding both ends, remove the door roller 44 from the rail 8, and place the lower end of the outer sliding door d2 on the board below the rail 8 of the lower frame 2, as shown in d' to e. When placed on the window frame F, the upper end of the outer sliding door comes off from the guide piece 7, and the outer sliding door can be moved indoors and removed from the window frame F.

As described above, according to this embodiment, the inner sliding door d1 can be removed first while the outer sliding door is still erected, and it can be easily removed by firmly holding both left and right ends of the inner sliding door with both hands. be able to.

Therefore, when you want to repair or replace only the inner sliding door, you can remove and install only the inner sliding door without having to remove the outer sliding door each time as in the past, making the work very efficient and easy. be able to.

When the doorstop part 22 is molded integrally with the vertical frame 4, it has the advantage of being easy to manufacture and providing great strength to the vertical frame, but as shown in FIG. It is also possible to make a rectangular tube-shaped or U-shaped doorstop part 22' and connect it to the vertical frame. In this case, as with the vertical frame 3, the base plate 16' and the protruding edge are connected to each other. The doorstop part 2 can be easily attached to the conventionally used vertical frame 4' having 17', 18', and 19'.
By attaching the window 2', it becomes possible to attach a ventilation system, easily remove and install the inner and outer sliding doors, and there is an advantage that a conventional window frame or an existing window frame can be used as is.

As described above, according to the present invention, only the door stop for the inner sliding door of the vertical frame is made to protrude in a rectangular tube shape inside the window opening, and the ventilation device is provided in the protruding part. The amount of material consumed for molding is reduced, and a ventilation function can be provided in the window frame at low cost.

Then, the amount of protrusion of the door drawing part for the inner sliding door is adjusted so that when both the inner and outer sliding doors are moved to the open side, a hand can be used to grasp the inner door between the inner door and the outer sliding door and between the inner door and the vertical frame. Since it is large enough to form a gap where it can be inserted, a ventilation system can be easily installed in the sliding door stop.
Ventilation efficiency also improves.

Furthermore, since the inner door can be held by hand at both ends with both the inner and outer sliding doors moved to the open side as described above, the inner door can be removed from the indoor side while the outer sliding door is still installed, or the inner door can be removed from the indoor side or Since it can be retracted, the difficulty of installing and removing the inner and outer sliding doors and the danger of the sliding doors falling, which were common to sliding windows, have been eliminated.
