Description

[Detailed Description of the Invention] This invention relates to a reversible window in which a shoji is attached in a reversible manner via upper and lower links fixed so as to be able to swing outward in the horizontal direction.

In this type of reversing window, one end of the shoji remains engaged with the upper and lower frames of the window frame, and the center of the width is pivoted at the tip of the link so that the shoji is inverted outwards around the engaging part. The door roller is attached to only one end of the shoji, but in the case of a conventional reversing window, the door roller has a structure that is strong enough to withstand the load from above.
In other words, it had the structure of an ordinary door roller that rotates on the top surface of the lower frame (Japanese Patent Application Laid-open No. 85078/1983,
Publication No. 96363). However, when the shoji is reversed, the majority of the shoji protrudes outside, which causes the door roller to be pushed toward the interior of the room, which has the disadvantage of interfering with the smooth running of the door roller.

In view of the above-mentioned circumstances, the purpose of this invention is to enable the door roller to run smoothly even when a force is applied to the door roller in the direction of the room.

The next embodiment of this invention will be explained based on the drawings.

Window frame A consists of left and right vertical frames 1, 1 and upper and lower frames 2, 3.
A single shoji B is attached to the window frame A, and windshield walls 4 and 5 are provided at the indoor end of each frame 1, 2, and 3 of the window frame A, and the windshield walls 4 and 5 A groove 6 is formed on the outer surface, and a tight material 7 is fitted into the groove 6.

Further, among the upper and lower frames 2 and 3, the upper frame 2 has a hollow protrusion 8 formed closer to the indoor side, and a hanging piece 9 in the center.
A guide strip 10 of the shoji B is formed by a groove between the protruding portion 8 and the hanging piece 9.
An L-shaped refraction piece 11 is provided protruding from the inner side edge of the groove opening. The lower frame 3 has running rails 13 for the main wheels 12 of an engaging door roller 32 (to be described later) protrudingly provided at positions corresponding to the guide strips 10 of the upper frame 2, and is engaged on the indoor side and the outdoor side of the running rails 13. Guide rail 1 of door roller 32
4 and 15 are provided protrudingly. And running rail 13
is formed lower, the outer guide rail 15 is formed higher than it, and the inner guide rail 14 is formed on the windshield wall 5 at a higher position than the traveling rail 13. Furthermore, a protruding piece 16 is provided between the inner guide rail 14 and the groove 6 on the windshield wall 5, and the fitting groove 19 for the connection aid 18 with the vertical frame 1 is formed by the protruding piece 16 and the lower wall 17 of the groove 6. The auxiliary tool 18 is provided with protrusions 16a, 1 on the groove edge.
A screw 16b is screwed into the auxiliary tool 18 from the vertical frame 1.

The shoji B engages with the upper and lower window frames 2 and 3 at one end as described above, and is also connected by upper and lower links 20 and 20. The link 20 has caps 22 and 23 at both ends of a main member 21 made of a hollow extruded member.
, and attach the bearing plate 24 to both caps 22 and 23.
25, and attach one shaft bearing plate 24 to the upper and lower frames 2,
3, and the other shaft bearing plate 25 is attached to the shoji B.
is fixed to the middle part of the upper and lower frames 26, 27,
28 is a rotation axis of the link 20 relative to the upper and lower frames 2 and 3, and 29 is a rotation axis of the shoji B relative to the link 20.

In addition, one vertical stile 30 of shoji B has an upper frame 2 at the upper end.
Attach the engagement piece 31 with the guide strip 10, attach the engagement door wheel 32 described above to the lower end, and attach the engagement piece 3 to the guide strip 10.
1 and the engaging door wheel 32 are each horizontally rotatable on the vertical stile 30. To install it, a vertically long shaft bearing piece 34 is fixed to the inner surface of the door end wall 33 of the vertical stile 30 with screws 35, and the engagement piece 31 and the rotating shaft 36 of the engagement door wheel 32 are fitted onto the shaft bearing piece 34. There is. The engaging piece 31 has a sliding piece 38 that fits on the guide strip 10 integrally fitted to the upper end of the L-shaped bent base plate 37, and the lower end of the base plate 37 is fixed to the rotating shaft 36. be. In addition, in the engagement door wheel 32, the main plate 39 is bent into two stages, upper and lower, and the upper part of the inverted L-shaped sub-plate 40 is fixed to the lower surface of the base of the upper stage, thereby forming the bearing frame 41 of the main wheel 12. With such a structure of the bearing frame 41, the main wheel 12 is positioned closer to the indoor side than the rotating shaft 36. Also,
A pair of left and right sub wheels 42, 42 are rotatably supported on the lower end of the main plate 39 so as to be rotatable in the horizontal direction. Furthermore, a sliding piece 43 is fixed to the outer surface of the lower end portion of the sub-plate 40 so as to make side contact with the outer guide rail 15. The main and sub-plates 39, 40 are fixed to the bearing piece 34 with a washer 44 interposed therebetween by an abutment shaft 36.

Note that the engagement piece 31 and the engagement door wheel 32 may be attached to the other vertical stile 45 in the same manner as described above, and conversely, one vertical stile 30 may be free from the window frame A. In addition, the free end of the shoji to which the engaging piece 31 and the engaging door wheel 32 are not attached has a door neck that engages with the guide strip 10 of the upper frame 2 to ensure stability when the shoji B is closed. A door stand or door wheel that can be received by the lower frame 3 may be attached.

In the reversing window of the above embodiment, the shoji B rotates half a turn around the shaft 29 at the tip of the link 20 and the shaft 36 of the engaging piece 31 and the engaging door wheel 32 as both shafts 29 and 32 move. At this time, the shaft 29 moves on the circumference R centered on the rotating shaft 28 of the link 20, and the shaft 36 moves along the guide strip 10, the traveling rail 13, and the guide rails 14, 15, that is, the upper and lower frames 2,
Move along 3. At this time, one end of the shoji B is kept hanging over the upper and lower frames 2 and 3, and the other end gradually protrudes until it becomes perpendicular to the upper and lower frames 2 and 3, as shown by the solid line in Figure 2. It gradually retracts as the apex, and as shown in Fig. 3, it is turned over and refitted into the window frame A.

In addition, in this case, the upper and lower links 20, 20 protrude simultaneously, the shoji B is supported by the rotating shafts 29, 29 at the center of the width, and the upper and lower rotating shafts 29, 29 are held coaxially, so that the engagement piece 31 and engaging door wheel 32
Both rotating shafts 36, 36 are also held coaxially. Therefore, the engagement piece 31 and the engagement door wheel 32
The state of engagement with the upper frame 2 and the lower frame 3 is stabilized by the upper and lower links 20, 20.

However, in the state where the shoji B protrudes, the engagement piece 31 at the upper end receives a force trying to move out from the frame A due to its relationship with its center of gravity, and the engagement piece 32 at the lower end is moved indoors from the window frame A. Receive the force that tries to pull you in.

However, in the lower frame 3, since the engaging door roller 32 is sandwiched between the inner and outer guide rails 14 and 15, the main wheel 12 does not come off the predetermined running rail 13, and therefore the height position of the engaging piece 31 is held, so the engaging piece 31 does not come off the guide strip 10 of the upper frame 2.

In addition, when the shoji B protrudes from the window frame A, the engaging door roller 32 is pressed against the inner guide rail 14, but the secondary wheel 42 rotating horizontally contacts the rail 14, and the main wheel 12 Since the auxiliary wheels 42 rotate when traveling, there is almost no frictional resistance in the movement of the door roller 32, and the shoji B can be reversed very smoothly, and there is no forced operation.
There is no fear that the stability of the shoji B during reversal will be lost.

Moreover, by locating the rotating shaft 36 on the outdoor side of the main wheels 12, the shoji B is supported by the main wheels 12 so as to fall outward, so that the state of contact with the inner guide rail 14 is stable. Retained.

Note that it is not contrary to the spirit of this invention even if the subwheel 42 is directly supported by the windshield wall 5 without providing the inner guide rail 14.

In addition, the width of the engaging piece 31 is made wider at the upper end of the shoji B, and the width of the lower part of the main plate 39 is made wider at the lower end to increase the distance between the left and right auxiliary wheels 42, 42. Inclination to the left and right is prevented, and the stability of the shoji B is ensured in this respect as well.

Furthermore, if the bending pieces 11 of the upper frame 2 and the inner guide rails 14 of the lower frame 3 are removed from both the left and right ends of the window frame A, when the shoji B is closed, it will be pulled inward and the tight material 7 The device can be locked in close contact with the device.

As explained above, the reversing window of this invention supports the engaging door roller at the lower end of the shoji by sandwiching it between the inner and outer rails, but the engaging door roller is equipped with auxiliary wheels that rotate in side contact with the inner rail. Because
The stability and operability of the shoji are very good, and since the rotating shaft of the engaging door wheel is located outside the main wheel, the contact of the auxiliary wheel with the inner rail is maintained at all times, which allows the shoji to This has the excellent effect of ensuring good stability and operability.

Furthermore, by arranging the rotation shaft of the link, the rotation shaft of the door roller, and the main wheel of the door roller from the outdoor side, the shoji can be opened, closed, and reversed very smoothly.
