Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding opening / closing window that can be opened and closed in a foldable manner.

[0002]

2. Description of the Related Art Conventionally, a window is usually of a sliding door type. However, as is well known, this type of window biases the window panel toward one side of the window frame when the window is opened. To do so.

[0003]

In the sliding door type window, it is not possible to open the entire opening of the window frame (one window panel is always closed), so that the feeling of release and breathability are improved. I'm still dissatisfied. Conventionally, hinged door type windows (those that swing and open) are used, but with this type of window, it is difficult to open and close because one side of the window panel has a large swing amount. When opened, the window panel was affected by the outside wind and was prone to rattling.

The present invention has been made in view of the above circumstances, and is a folding opening / closing window capable of satisfying a feeling of openness and breathability when a window is opened and improving operability. The purpose is to provide.

[0005]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the present invention, one or more window panels are provided for the window frame,
It is characterized in that the window panel has a pair of left and right panel components which are connected to each other in a butterfly motion.

With this structure, the window panel can be folded in two when the window is opened, so that the entire opening of the window frame can be substantially opened. Therefore, the feeling of openness and breathability can be satisfied. A swing support pin that can be operated in the vertical direction is provided on at least one side edge portion of the window panel, and a pin receiving portion that can be engaged with the swing support pin near at least one vertical rail of the window frame. Can be provided.

With this structure, the window panel can be folded around the swing support pin while the window panel is biased toward one of the vertical bars of the window frame.
The swing support pins of the window panel are provided so as to project vertically at both outer side edge portions of both panel constructions, and the window frame has a pin receiving portion individually corresponding to each swing support pin. It is preferable that the upper rail and the lower rail of the window frame are provided with guide rails for connecting the left and right pin receiving portions.

With such a structure, when the window panel is folded, it can be biased to any of the left and right vertical bars with respect to the window frame. That is, since the opening can be freely selected, it is possible to obtain the convenience that the opening and closing can be appropriately performed according to the sunshine, the wind direction, the arrangement of furniture and the like.
In addition, the opening and closing of the window panel can be stably performed, and the state after opening the window panel is less likely to be affected by outside wind or the like.

The rocking support pins forming a pair above and below the window panel may be vertically moved in the mutually approaching and mutually separating directions by a handle operation. With such a configuration, there is an advantage that the opening / closing operation of the window panel can be easily performed.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 shows a folding opening / closing window 1 according to the present invention. This folding opening / closing window 1 includes a window frame 2
For that, one window panel 3 is fitted in the opening,
The window panel 3 has a pair of left and right panel structures 4 and 5.

In the window panel 3, both panel components 4,
5 are connected to each other by a pair of upper and lower hinge tools 7 (see, for example, FIG. 7). Therefore, these panel structures 4,
5 is a double-folded fold as shown by the solid line in FIG.
In the same manner, the butterfly motion can be freely performed between the flat development as shown by the chain double-dashed line. At the left and right side edge portions of the window panel 3, that is, at the opposite side edge portions of the panel components 4 and 5, there are provided grips 10 that project only toward the indoor side. Further, swing support pins 12 are provided which project coaxially upward and downward from upper and lower end surface portions of the grips 10 on the upper side and the lower side, respectively.

On the other hand, in the window frame 2, as shown in FIGS. 2 and 3, the rocking support pins 12 can be engaged with the respective facing inner surfaces of the upper bar 14 and the lower bar 15 near the vertical bars 16. The pin receiving portion 17 is provided. The left and right pin receiving portions 17 of the upper rail 14 and the left and right pin receiving portions 17 of the lower rail 15 are connected to each other by a groove-shaped guide rail 18. The guide rail 18 is formed with a sloped portion 18a that sharply reduces the groove depth at the connection portion with the pin receiving portion 17 as shown in an enlarged view in FIG.
The pin receiving portion 17 and the guide rail 18 are prevented from being completely and directly communicated with each other.

Incidentally, the pin receiving portion 17 and the guide rail 18
4 is formed by inserting a grooved strip into the U-shaped strips forming the upper bar 14 and the lower bar 15 of the window frame 2 as shown in FIG. 4, thereby facilitating production. Also, the manufacturing cost is reduced. In the window panel 3, the swing support pins 12 provided above and below and to the left and right as described above are provided with drive rods 24 extending in the vertical direction inside the side edge portions of the panel constructing bodies 4 and 5 as shown in FIG. Has been.

The upper drive rod 24 provided on the upper swing support pin 12 and the lower drive rod 24 provided on the lower swing support pin 12 pass each other and face each other. Rack teeth 25 are formed in each of them, and a pinion gear 26 that meshes with both rack teeth 25 is rotatably interposed between them. The above-mentioned handle 10 is provided for one of the upper and lower drive rods 24.

Therefore, the upper and lower swing support pins 12 move up and down so as to approach and separate from each other in synchronization with each other via the upper drive rod 24 and the lower drive rod 24. In addition,
The upper drive rod 24 and the lower drive rod 24 are maintained in the upward projecting state or the downward projecting state by the compression springs 28 or 29, etc. provided at appropriate places, and are also capable of automatically returning when they are forcibly retracted. Has become.

As is apparent from the above, FIG.
In the closed state of the window panel 3 shown in FIG. 3, the swing support pins 12 are engaged with the pin receiving portions 17 of the window frame 2 and do not come out to the guide rail 18 side. The expanded state is maintained without rattling under the influence of outside wind or the like. From this state, for example, when the handle 10 in the right panel structure 5 in FIG. 2 is moved slightly upward while being moved upward, the upper swing support pin 12 is moved downward and the lower swing support is supported. The pins 12 retreat upward, respectively, and both are disengaged from the pin receiving portions 17 of the window frame 2. Therefore, the window panel 3 uses the upper and lower swing support pins 12 in the left panel structure 4 as an opening / closing axis and the swing fulcrum of the hinge tool 7 connecting the panel structures 4 and 5 as a folding axis, and the solid line in FIG. As shown in the figure, it is possible to fold and open toward the left and outdoors. At this time, the upper and lower swing support pins 12 in the right panel structure 5 are
Sliding in the guide rail 18 of the window frame 2 ensures stable operation.

On the other hand, in order to close the window panel 3 from this open state, it suffices to pull the handle 10 of the right panel structure 5 horizontally to the right. That is, the upper and lower swing support pins 12 in the right panel structure 5 slide in the guide rails 18 of the window frame 2 and move to the pin receiving portions 17, so that the slope portions 18a in the guide rails 18 (see FIG. 5). ), It is automatically pushed in and out, and is smoothly guided into the pin receiving portion 17.

The window panel 3 is the opposite of that shown in FIG.
It is also possible to fold the panel structure 4 on the left side of the inside toward the right side and open it. Also, in some cases,
It is also possible to fold the left and right panel structures 4 and 5 in half at the center of the left and right sides of the window frame 2. 7, 8 and 9
As shown in Fig. 5, the hinge tool 7 in the illustrated example has a configuration in which the swing shaft 31 is projected from the mounting portion 30 to the panel construction bodies 4 and 5 to the indoor side. When it is closed (see FIG. 8), it is possible to improve the adhesion by abutting the two, and when folding the panel constructions 4 and 5 (see FIG. 9), a gap G for preventing mutual interference is obtained between the two. I am allowed to do so. When the panel constructions 4 and 5 are closed in a flat plate shape, rainwater, dust,
Alternatively, in order to more surely prevent the invasion of insects and the like, a cover bar 33 (see also FIG. 1) for covering the joint portion from the outdoor side is provided for one panel structure 5. It is provided.

Further, in the window frame 2, as shown in FIGS. 2, 3 and 4, a fixture 3 such as a screen door is provided at four corners facing the indoor side.
5 is provided to prevent the invasion of insects when the window panel 3 is opened, and as shown in FIG. 4, an eaves portion 36 serving as a shade and a rain shield is provided at the upper part on the outdoor side.
10 and 11 show a second embodiment of the present invention, in which the upper and lower sliding support pins 12 move up and down by the drive rod 24 having the rack teeth 25 and the pinion gear 26 as described above. Instead of this, a wire 38 is provided between the swing support pins 12, and the grip 10 engaged with the wire 38 moves up and down so as to approach and separate from each other.

The handle 10 is rotatably supported in a direction in which the wire 38 is bent laterally. When the handle 10 is operated in the direction shown by the arrow A in FIG. 11, the wire 38 is bent laterally. , The upper swing support pin 12 retracts downward, and the lower swing pin 12 retracts upward. In addition, the handle 10
If the operation direction (arrow A) of is aligned with the opening direction of the panel structure bodies 4 and 5, the reciprocating operation of the swing support pin 12 and the opening operation of the panel structure bodies 4 and 5 are easy with one operation. You can do it.

Rollers 39 are provided at the respective vertical positions of the handle 10, and the wire 38 is curved with these rollers as fulcrums. Further, the swing support pin 12
The spring 40 maintains the upward protruding state or the downward protruding state, and is also capable of automatically returning when forcedly retracted. Although the handle 10 shown in the drawing merely engages with the wire 38, a vertical through hole may be provided in the handle 10 and the wire 38 may be passed through the through hole.

Further, although not shown, a lock member capable of locking the rotation of the handle 10 when the wire 38 is bent may be provided. In that case, the wire 38 may be lockable even in a non-curved state. FIG.
Shows a third embodiment of the present invention, in which a cutout portion 41 is formed on the indoor side of the pin receiving portion 17 of the window panel 2.

The vertical cutout length of the cutout portion 41 is slightly smaller than the vertical cutout length of the pin receiving portion 17.
With the window panel 3 closed, for example, when the swing support pins 12 of the right panel structure 5 are moved up and down in a mutually close proximity to each other and the window panel 3 is pulled indoors, the swing support pins 1
2 goes out of the pin receiving portion 17 from the notch portion 41. In this case, the swinging support pin 12 of the left side panel structure 4 can serve as a hinged door that can be opened and closed.

That is, in the case where a shutter is located on the outdoor side of the window panel 3, it is necessary to open the window panel 3 to open and close the shutter, but the shutter is located on the outdoor side. Therefore, it is difficult to fold and open the window panel 3 to the outdoor side. However, by providing the cutout portion 41, even if the folding door cannot be opened to the outdoor side because the shutter is located on the outdoor side of the window panel 3, the window panel 3 can be opened to the indoor side. It is possible to open shutters etc. in the state.

The present invention is not limited to the above embodiment. For example, the window frame 2 may be provided with a plurality of window panels 3. Further, in the window panel 3, a vertical operation operation of each swing support pin 12 may be performed by providing a dedicated operation section different from the handle 10. The structure in which the upper and lower swing support pins 12 are synchronously moved toward and away from each other is, for example, a structure in which both ends of a lever swingable by a rotary knob are connected to the upper and lower swing support pins 12 by link rods. Can be replaced with a structure. It should be noted that a structure without synchronization may be used.

The closed state (flat plate-shaped developed state) of the window panel 3 is not limited to that by the engagement between the swing support pin 12 and the pin receiving portion 17, and, for example, the side edge portions of the respective panel components 4 and 5. You may use the sickle lock etc. which are provided between the vertical crosspiece 16 of the window frame 2. Although the window panel 3 (panel construction bodies 4 and 5) is opened outward in the above-mentioned embodiment, it can be opened inside by changing the mounting position and type of the hinge tool 7, and in some cases, can be opened inside and outside. It is also possible to

[0027]

As is apparent from the above description, according to the present invention, the window panel provided on the window frame has a pair of left and right panel constructions which can freely move in a butterfly manner. The panel can be folded in two, which allows the entire opening of the window frame to be substantially opened. Therefore, the feeling of openness and breathability can be satisfied.

If at least one side edge of the window panel is provided with a vertically movable swing support pin and a window frame is provided with a pin receiving portion for receiving the swing support pin, it is biased to one side of the window frame. Now you can fold the window panel. If swing support pins are provided at the top, bottom, left and right corners of the window panel, the same number of pin receiving parts are also provided on the window frame, and guide rails connecting the left and right pin receiving parts to the upper and lower bars are provided. ,
The window panel can be folded from either the left or right side. In other words, you can freely choose the opening
The convenience that the opening and closing can be appropriately performed according to the sunshine, the wind direction, the arrangement of furniture, and the like can be obtained. In addition, the opening and closing of the window panel can be stably performed, and the state after opening the window panel is less likely to be affected by outside wind or the like.

If the rocking support pins forming a pair above and below the window panel are operated by a handle, there is an advantage that the window panel can be easily opened and closed.
