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 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 devised to solve these problems, and is provided with a means between the upper stile and the hanging frame of the door to temporarily press them against each other when the door turns. By having such a configuration,
When the door swings, the door pivots while being firmly supported by the fixed side, so there is no tilting of the door or falling of the door tip.

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

The same parts as in Fig. 1 are given the same reference numerals. In Fig. 4 and Fig. 7, reference numeral 1 denotes a gable installed horizontally along a ceiling or the like, and within this gable 1, rail support frames 18 are attached at specified intervals, and the upper rail 2 is attached horizontally to mounting pieces 19 protruding laterally from these rail support frames 18. Reference numeral 4 denotes a hanging frame, and pulley plates 20 are fixed to both ends of the upper surface of this hanging frame 4, and on this pulley plate 20, a pulley 3 that slides on the upper rail 2 and two guide wheels 21, 21 that come into contact with the underside of the upper rail 2 to prevent it from coming off 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. It is mounted by a pivoting fulcrum portion 11 consisting of a self-aligning washer 30, a thrust bearing 31, a washer 32, and a nut 33, so as to be possible. The upper surface of the end 27 of the horizontal arm 23 has this end 2
A sliding chip 34 made of hardened metal with a rounded upper part and less wear is fixed to the sliding chip 34, which protrudes slightly from the upper surface of the chip 7. 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. The cam plate 35 has a hole 36 in the center that coincides with the shaft hole 29, and an uneven surface 37 is formed on the lower surface of the half circumference of the hole 36.
As shown in FIG. 6, when the door 5 slides to open and close, the position of contact with the sliding tip 34 is defined as 0 degrees, and this uneven surface 37 is at this 0 degree.
It has a concave portion 38 having the same height at 90 degrees, 180 degrees, and a convex portion 39 at 45 degrees and 135 degrees. The cam plate 35 and the sliding tip 34 constitute an upper swing position holding section 40.

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 out 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 part 40, the sliding tip 34 is in contact with the concave part 38 of the cam plate 35, but as the door 5 rotates, the sliding tip 34 is in contact with the convex part 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. When the door 5 reaches the 90 degree rotated position in this manner, 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 is also 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 rotated 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 sliding chip and a cam plate in contact with the sliding chip are provided near the pivot shaft that connects the horizontal arm provided on the upper stile and the hanging frame. The board has concave and convex sections that change continuously, so that when the door swings, the door tip lifts up slightly. This results in
The door can be opened and closed smoothly without the tip of the door scraping on the floor. In particular, the door is made of a single glass plate,
Suitable for cases where the upper and lower frames are the only ones holding the frame.
