Description

[Detailed description of the invention] Industrial application field This invention is a reversible window that allows the indoor and outdoor sides to be completely replaced without having to take out the shoji installed inside the window frame to the indoor side. Regarding the improvement of

Prior Art This type of reversing window basically uses a link device, for example, as shown in Utility Model Application Publication No. 56-41081, by moving one end of the shoji along the upper and lower frames of the window frame to 1/2 the width of the shoji.
The position No. 4 and the center position of the window frame are connected by a link having a length of 1/4 of the width of the door, and the reversing operation is performed.

In order to reverse the operation, it is necessary to first push the shoji toward the outside and then pull it back.
Previously, shoji did not have appropriate operating points, making reversing windows particularly difficult to handle, such as pressing the glass part. In addition, since rotation around the guide member is involved when opening and closing, there is a situation where the guide member is forced to pass through while biting into the frame gasket of the vertical stile on the side where the guide member is installed at the beginning and during the reversing operation. There were disadvantages such as making unpleasant noises and prematurely damaging the frame gasket.

Problems that the invention aims to solve This invention makes it easy to open, close, and flip the shoji.
In particular, the object is to provide a reversible window in which a vertical stile that moves along upper and lower frames can be smoothly opened and closed and reversed without interfering with frame packing, and has a good appearance.

Measures to solve the problem A handle is installed on the shoji of the reversing window, and the guide member that guides the shoji along the longitudinal direction of the upper and lower frames is of a size that fits within the cross-sectional area of the attached stile, and is attached to one vertical stile of the shoji. Place it above and below. In addition, the interior and exterior corners of the stile's prospective surface are chamfered to prevent interference with the frame packing.

Operation The window is opened, closed, and reversed by the reciprocating swing of the arm relative to the frame and the rotation of the shoji relative to the arm in a manner that allows one vertical stile to follow the upper and lower frames.

At this time, the guide members that guide one of the stiles are placed above and below the stiles, but since the interior and exterior corners of the vertical surfaces of this stiles are sufficiently chamfered, can be moved without interfering with frame packing.

Also, depending on the handle, the operating points for opening/closing the window or reversing the window are clearly indicated.

Embodiment Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

As shown in FIG. 1, the reversible window 1 of the present invention is constructed by combining a shoji 3 inside a rectangular window frame 2. The window frame 2 is constructed by fixing an upper frame 6 and a lower frame 7 to the upper and lower positions of a pair of left and right vertical frames 4 and 5. As shown in FIG. 2, the upper frame 6 has a U-shaped cross section and has a downwardly extending guide groove 8 formed in its lower part along the longitudinal direction, and a retaining plate 9 extending downwardly on its lower surface closer to the interior of the room. There is. In addition, the lower frame 7 as a whole has a substantially L-shaped cross section, and a rail 11 at the drainage surface 10.
, and a water return plate 12 is formed upward at the end on the indoor side, and the water return plate 12 integrally forms a retaining plate 13 extending toward the indoor side. As shown in FIG. 3, the pair of vertical frames 4 and 5 have a substantially U-shaped cross section and integrally form retaining plates 14 and 15 on opposing surfaces. The retaining plates 9, 13, 14, 15 have gasket retaining grooves 16, 17, 1 on the outdoor side.

As shown in FIG. 1, the shoji 3 is constructed as a frame body having a size that fits inside the window frame 2, with horizontal frames 23 and 24 fixed at the upper and lower positions of a pair of vertical frames 21 and 22. , holds a glass plate 25 inside thereof. One vertical stile 22 has a chamfered shape by extrusion molding the interior and exterior corners of the prospective surface to have a rounded corner cross section. The other stile 21 has a substantially rectangular cross section, and these stile 21, 22
Forms storage grooves 26 and 27 for storing the glass plate 25 on opposing surfaces. Also, the upper horizontal stile 23
forms a storage groove 29 for the plate glass 25 together with an auxiliary stile 28 fitted into its lower surface, and the lower horizontal stile 24 has a handle portion 31 shaped like a letter in cross section protruding toward the outdoor side and the indoor side on the upper surface. , 32,
A housing portion 30 for the plate glass 25 is formed between them. The plate glass 25 is mounted on the glass receiver 33 inside the storage groove 30 of the lower side stile 24, and is inserted into the storage grooves 26, 27, 29 by the glass gasket 34.
It is held in 30 parts.

Further, the upper frame 6 and lower frame 7 of the window frame 2 are connected to the shoji 3 by arms 35 and 36 at upper and lower positions, respectively, as shown in FIGS. 4 and 6. That is, as shown in FIG. 4, one end of the upper arm 35 is rotatable by a pin 39 with a washer 38 interposed with respect to an L-shaped bracket 37 attached to the outdoor surface of the upper frame 6. The other end of the arm 35 is supported by the washer 4.
The shoji 3 is rotatably supported by a pin 41 to a mounting bracket 42 located approximately at the center of the shoji 3 in the width direction of the door. Also, one end of the lower arm 36 is rotatable by a pin 45 with a washer 44 interposed between an L-shaped bracket 43 attached to the outdoor side surface of the lower frame 7, as shown in FIG. The other end of the arm 36 is rotatably connected by a pin 48 with a washer 47 interposed to a mounting bracket 46 attached to the center of the horizontal stile 24 below the shoji 3. There is. The pins 39 and 45 are located on the outdoor side of the guide groove 8. Here, the lengths of the upper and lower arms 35, 36 are set to approximately half the width of the door of the shoji 3, and the brackets 37, 43 are attached to the upper frame 6 or lower frame 7 by mounting screws 49, 50, respectively. It is attached to the outside surface. In addition,
The mounting brackets 42 and 46 are shown in FIGS. 5 and 7, respectively.
As shown in the figure, it has an upwardly convex or downwardly convex shape, and is attached to the upper surface of the horizontal stile 23 of the shoji 3 or the lower surface of the lower horizontal stile 24 with mounting screws 51 and 52 at both ends.

Further, the other vertical stile 22 has a roller 53 as a guide member at its upper end, and supports a door roller 54 as a guide member running on the rail 11 at its lower end. As shown in FIG. 8, the roller 53 is rotatably supported on a vertical shaft 57 of an L-shaped support fitting 56 fixed to the upper end thereof with a mounting screw 55 so as to fit within the cross-sectional area of the vertical stile 22. and extends into the guide groove 8 of the upper frame 6. Further, the door roller 54 is connected to the leg 5 by an axle 58 as shown in FIG.
9 is rotatably supported, and this leg 59
is rotatable about the vertical axis 60 and the bush 6
1 and 62 are interposed therebetween, and is attached to the lower surface of the housing 63. This housing 63 has an L-shape as a whole and is fixed to the lower surface of the lower horizontal stile 24 with a mounting screw 65 with a seat plate 64 interposed at one end, and the vertical stile 2
It is fixed to the lower inner surface of 2.

The roller 53 and door roller 54 described above are not limited to this,
Move along the longitudinal direction of the upper frame and lower frame, and move along the vertical axis 5
Any guide member may be used as long as it rotates without protruding from within the cross-sectional area of the frame attached via the guide members 7 and 60.

In addition, the prospective indoor and outdoor corners of the vertical stile 22 are as follows:
When the vertical stile 22 moves in the longitudinal direction of the upper and lower frames and rotates around the vertical axis of the guide member, its locus may be chamfered as an inclined surface or curved surface that does not interfere with the frame gasket.

As mentioned above, the shoji 3 is rotatably supported by the upper and lower arms 35 and 36 inside the window frame 2, and is movable along the upper frame 6 and the lower frame 7 at one vertical stile 22. The other vertical stile 21 is supported by the window frame 2 and is free from the window frame 2. As shown in FIGS. 2 and 3, this shoji 3 is pulled toward the indoor side by a locking device (not shown), and is held in close contact with the window frame 20.
The opening is closed.

Next, the function and operation of the rotating window 1 will be explained.

Holding the handle 34, as shown in FIG. 10A, while pressing one of the stiles 21 from the indoor side toward the outdoor side, push the other stave 22 from the side of one stave 5 to the side of the other stave 4. move in the direction. In this way, the shoji 3 rotates counterclockwise about the pins 41 and 48 and is opened while protruding toward the outdoors at an angle. Normally, the opening angle of the shoji is fixed at an angle of 30° or 90° with respect to the upper and lower frames using an appropriate stopper.

When it is necessary to replace the glass plate 25 or clean its exterior surface, the operator further rotates the shoji, inverts it, and switches its left and right ends, as shown in FIGS. 10B and 10C. Of course, at this time, the upper and lower arms 35, 36 are performing reciprocating rocking movements centering on the pins 39, 45. Now, since the guide members mentioned above are pivotally mounted on the top and bottom of the vertical stile 22, during such opening/closing or reversing operations, the vertical stile 22 rotates around the vertical axis of the guide member. If the corners a and b (FIG. 10A) are not chamfered, at the beginning of operation, the indoor corner b of the vertical stile 22 in FIG. 10A is the same as that in FIG. 10C. In this case, the outdoor corner a rotates to bite into the frame packing 20, causing interference, but in the present invention, the corners a and b are chamfered as described above, so no interference with the frame packing occurs. Rotation is smooth.

Note that the upper and lower arms 35, 36 do not overlap with the horizontal frames 23, 24 of the shoji 3 during the reversing operation, that is, the pins 39, 45 do not overlap with the side frames 23, 24 of the shoji 3 during the reversing operation.
Since the pins 41, 48 and the vertical axes 57, 60 are always at the apex positions of the triangle when viewed from above, the restraint on the moving direction of the shoji 3 is not released, and the reversing movement of the shoji 3 becomes unstable during the movement. This means that you can do it without getting into this state. Also, the upper and lower pins 39 and 45 are connected to the window frame 2.
By protruding outward from the outdoor side of the shoji, the arms 35, 36 and the guide members 53, 54 are prevented from interfering with each other when the shoji 3 is reversed.
The shoji 3 can fit inside the window frame even when inverted.

Effects By installing a handle on the reversing window, it is easy to open, close, and reverse the window.

Guide members for moving one of the vertical frames along the upper and lower frames are arranged above and below the vertical frame so that they fit within the cross-sectional area of the vertical frame, so there is no large gap between the shoji vertical frame and the vertical frame, and the window Good appearance. Moreover, the interior and exterior corners of the vertical stile are chamfered to prevent interference with the opposing frame gasket, which may cause unpleasant noises when the window is opened or closed, or damage to the frame gasket during the frame period. There is no need to put it away.
