Description

[Detailed description of the invention] This invention is a door that opens and closes by sliding, but can also be opened and closed by swinging if necessary, and the opening and closing of the door ensures support of the pivot point during swing. It is related to the device.

The applicant has already proposed a door that can be opened and closed by both sliding and swinging as shown in FIGS. 1 to 3. This is Mume 1
A hanging frame 4 is attached to the upper rail 2 inside through pulleys 3, 3.
is hung, and a door 5 is further hung from this hanging frame 4. Then, by the forward and reverse rotation of the drive device 6, both doors 5, 5 slide from side to side along the closing doors 9, 9 together with the hanging frames 4, 4 via the belts 7, 7 and pulleys 8, 8. Open and close by.

If you need an opening wider than the door 5, such as when transporting large items or in case of a fire, you can push the door 5 outward as shown in Figure 3.
The door 5 swings around the swing fulcrum 11 when the engagement part 10 with the hanging frame 4 comes off, and the sliding door 9 is also pushed out by the swing of the door 5 and swings around the upper and lower swing fulcrums 12 and 13. swing to. Even when the doors 5, 5 remain open, they slide to the positions of the pillars 14, 14 on both sides, and a frontage twice as large as usual is obtained.

In this way, the door 5, which opens and closes by sliding and swinging, has a pivot point 1 with the hanging frame 4 when swinging.
1, that is, one end of the upper stile 15 of the door 5 supports the entire load of the door 5. In particular, as shown in FIG. 1, when the door 5 is made of a single glass plate 16 and is held only by the upper and lower frames 15 and 17, and does not have left and right frames, the entire load of the door 5 is supported. It is extremely difficult to open and close the structure by swinging the engaging part 1.
If it deviates from 0, the door 5 tilts and the lower end (edge) of the door 5 slides on the floor, causing a problem that it cannot be opened and closed smoothly.

The present invention was made to solve these problems, and it temporarily presses the door between the upper stile and the hanging frame and/or the lower stile and the rail when the door turns. This means that there is a means to do so.
With such a configuration, when the door swings, the door pivots while being firmly supported by the fixed side, thereby eliminating the possibility of the door tilting or the door tip sliding down.

An embodiment of the present invention will be described below with reference to the drawings.

Note that the same parts as in FIG. 1 are given the same reference numerals. In FIG. 4 and FIG. 7, reference numeral 1 indicates a blind installed horizontally along the ceiling, etc., and within this blind 1, rail support frames 18 are installed at predetermined intervals. The upper rail 2 is horizontally attached to a mounting piece 19 that protrudes laterally from the top. Reference numeral 4 denotes a hanging frame, and a pulley plate 20 is fixed to both ends of the upper surface of the hanging frame 4, and the pulley plate 20 includes a pulley 3 that slides on the upper rail 2, and a lower surface of the upper rail 2. Two guide wheels 21, 21 for preventing dislodgement that come into contact with are provided.

The door 5 has upper frames 15 at the upper and lower ends of the glass plate 16.
and the lower stile 17 are fitted, and the upper stile 15
A horizontal arm 23 is attached to a horizontal fixed frame 22 inside with screws 24, 25, and 26.
Among these screws 24, 25, 26, the center screw 25 is for connecting the fixed frame 22 and the horizontal arm 23, and the other screws 24, 26 on both sides are for connecting the horizontal position of the door 5 and the horizontal arm 23. It is for adjustment. The end 27 of the horizontal arm 23 is bent upward by a slight angle θ, and a pivot shaft 28 perpendicular to the bent end 27 is integrally fixed thereto. Therefore, this pivot axis 28 is also inclined inwardly by a slight angle θ with respect to the vertical line l. The pivot shaft 28 is loosely fitted into a shaft hole 29 formed at the end of the hanging frame 4, and the pivot shaft 28 is provided at an upwardly protruding portion thereof to rotate while slightly swinging around one point of the shaft center. As possible, it is attached by a pivot point 11 consisting of a self-aligning washer 30, a thrust bearing 31, a washer 32, and a nut 33. On the upper surface of the end 27 of the horizontal arm 23, there is a sliding chip 34 made of hardened metal with a rounded upper part and less wear, which protrudes further from the upper surface of the end 27.
is fixed. Further, a cam plate 35 as shown in FIG. 5 is provided on the lower surface of the hanging frame 4 at a position in close contact with the sliding tip 34. This cam plate 35 has a hole 36 in the center that coincides with the shaft hole 29.
The lower surface of the half circumference of this hole 36 has an uneven surface 3.
As shown in FIG. 6, when the door 5 slides to open and close, the position at which it contacts the sliding tip 34 is 0 degrees, and the uneven surface 37 has an angle of 0 degrees, 90 degrees, 180 degrees are the same height recesses 38,
It has a continuous curved surface that forms convex portions 39 at angles of 45 degrees and 135 degrees. By this cam plate 35 and the sliding tip 34, the upper turning position holding part 4
0 is configured.

Next, FIGS. 8 and 9 show the lower end of the door 5 and the lower rail 41, and the lower stile 17 of the door 5.
A U-shaped support plate 4 is mounted on a horizontal fixed frame 42 inside the
3 is fixed to the support plate 43, and a vertical hole 14 is bored in the center of the support plate 43 at a position whose center substantially coincides with the upper pivot point 11. In addition, this support plate 4
An upper cam plate 47 having a hole 45 bored in the center and an uneven surface 46 formed on the lower surface is welded downward to the lower surface of the cam plate 3 . A bolt 49 serving as a vertical shaft is inserted vertically into the lower rail 41 from the center of the lower surface of a guide rod 48 in the shape of an elongated rectangular bar, and this guide rod 48 is slidably inserted.
Bolt 4 as a vertical axis perpendicular to the center of the bottom surface of 8
9 is inserted, and a lower cam plate 52 having a bolt through hole 50 in the center and an uneven surface 51 formed on the upper surface is welded upward to the center of the upper surface of this guide rod 48. At both ends of 48,
Guide wheels 54, 54 are provided to smoothly slide within the groove 53 of the lower rail 41. As shown in FIGS. 10 and 11, the uneven surface 46 of the upper cam plate 47 has a center angle of 30 to 60 degrees and a center angle of 120 to 60 degrees.
Convex portion 55 at 150 degrees, 210-240 degrees and 300-330 degrees
The central angles of 75 to 105 degrees, 165 to 195 degrees, 255 to 285 degrees, and 345 to 15 degrees are the concave portions 56, and the rest are the inclined portions 5.
7, and the height difference between the convex portion 55 and the concave portion 56 is specifically 3 mm, and the diameter is 40 mm.
Further, the uneven portion 51 of the lower cam plate 52 has a first
As shown in Figures 2 and 13, the central angle is 75~
The convex portions 58 are 105 degrees, 165 to 195 degrees, 255 to 285 degrees, and 345 to 15 degrees, and the central angles are 30 to 60 degrees, 120 to 150 degrees, and 210 degrees.
~240 degrees and 300 to 330 degrees are concave parts 59, and the rest is an inclined part 60, and the convex part 58 and the concave part 5
Specifically, the height difference of 9 is 3 mm and the diameter is 40 mm. As shown in FIGS. 8 and 9, with the upper and lower cam plates 47 and 52 in mesh with each other, the lower cam plate 52, upper cam plate 47, and support plate 43 are penetrated from below the guide rod 48. Then, insert the vertical shaft 49, interpose the coil spring 61 and washer 62, and fix with double bolts 63. This causes the guide rod 48 to be lifted upward. At this time, a gap d, specifically about 1 mm, is created between the lower surface of the lower cam plate 52 and the upper surface of the lower rail 41, which is slightly smaller than the high resistance difference between the uneven portions 46 and 51. In this way, the lower swing position holding section 64 is constituted by the upper and lower cam plates 47, 52, and the like.

Next, the operation of the above configuration will be explained.

Regarding the sliding opening and closing of the door 5, there is no difference from the explanation in FIG. 1.

When opening and closing the door 5 by swinging, the door 5 is pushed from the indoor side to the outdoor side. Then, door 5 and hanging frame 4
When the engagement part 10 is disengaged from the pivoting fulcrum part 11
Open by swinging around the center. To explain in more detail, first, in the upper rotation position holding section 40, the sliding tip 34 is in contact with the concave portion 38 of the cam plate 35, but as the door 5 rotates, the sliding tip 34 is in contact with the convex portion 38.
9, the pivot shaft 28 rotates slightly around the thrust bearing 31, and the door tip is lifted. When the door 5 opens 45 degrees, it comes into contact with the highest convex portion 39, and the door 5 pivots while being firmly held by the hanging frame 4. At this time, the load of the door 5 applies an upward lifting force to the upper rail 2 via the hanging frame 4, but this force is supported by the two guide wheels 21, 21 and the pulley 3. When the door 5 is pivoted further, the sliding tip 34 moves into the recess 38, and in the 90 degree position the door tip returns to the horizontal position. The force generated in the lateral direction of the door 5 at this 90 degree position is supported by the guide rod 48 being in contact with the groove 53 of the lower rail 41.

Next, when the lower swing position holding portion 64 is moved by sliding, the upper and lower cam plates 47 and 52 are engaged with each other, so that a gap d is created between the lower cam plate 52 and the lower rail 41. When the door 5 is pushed out and begins to rotate, the upper cam plate 47 integrated with the door 5
It also rotates. However, since the lower cam plate 52 is integrated with the guide rod 48 and is prevented from turning by the lower rail 41, the convex part 55 of the upper cam plate 47 rides on the convex part 58 via the inclined part 60 of the lower cam plate 52. As the lower cam plate 52 moves upward, the coil spring 6
1, and when the door 5 turns 45 degrees, the lower cam plate 52 is pushed out to the lowest position. Then, the lower surface of the lower cam plate 52 comes into close contact with the upper surface of the lower rail 41, the gap d disappears, and the door 5 pivots while being firmly held by the lower rail 52. Furthermore, when the door 5 is rotated to reach the 90 degree position, the convex portion 55 and the concave portion 59 of the upper and lower cam plates 47 and 52 engage, and the lower cam plate 52 is raised by the coil spring 61.
A gap d is created again.

In this way, when the door 5 reaches the 90 degree rotated position, the door 5 can be opened and closed by sliding as it is.

Incidentally, when the door 5 is opened and closed by swinging, it goes without saying that the fitted door 9 can be opened and closed by swinging as shown in FIG.

To return the door 5 and the jammed door 9 to their original states, they can be turned in opposite directions by hand.

In the embodiment described above, the sliding tip 34 of the upper rotating position holding part 40 is made of metal with a rounded shape on the upper part, but the present invention is not limited to this. Board 35
may be brought into contact with.

As mentioned above, this invention also uses slides to
In addition, in a door that can be opened and closed by swinging, a swing position holding part is provided between the hanging frame and the upper stile and/or between the lower stile and the lower rail, so that the door will not be able to handle the load when swinging. is supported by the swivel position holding part, so there is no tilting when swinging, such as when the door swings down.
It can be opened and closed smoothly.
