Description

[Detailed explanation of the invention] This invention is a door that can be opened and closed by sliding, but can also be opened and closed by swinging if necessary, so that the hanging frame, etc. for hanging the door is on the side of the door when swinging. This invention relates to a door opening/closing device that can be opened and closed reliably without being deformed by the force received from the door.

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.

Therefore, in order to solve the above-mentioned problems, the present applicant has provided the door 5 with a rotating structure between the upper stile 15 and the hanging frame 4, and between the lower stile 17 and the lower rail 41, as shown in FIG. It has already been proposed that swing position holding means 40 and 64 are provided which temporarily press against each other. However, with this method, a slight problem occurred in that the hanging frame etc. swayed laterally. More specifically, in Figures 4 and 5, numeral 1 is a hole provided horizontally along the ceiling, etc., and inside this hole 1,
Rail support frames 18 are attached at predetermined intervals, and the upper rail 2 is horizontally attached to attachment pieces 19 that project laterally from the rail support frames 18.
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. Guide wheel 2 to prevent dislodgement that comes into contact with
1 is provided.

The door 5 connects the upper and lower ends of the glass plate 16 to the upper stile 15.
and the lower stile 17 are fitted, and the upper stile 15
A right-angled pivot shaft 28 is integrally fixed to the.
The pivot shaft 28 is 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 so that the pivot shaft 28 can be rotated while slightly swinging around one point of the shaft center. As possible, it is mounted by a pivot point 11 consisting of a thrust bearing 31 and a nut 33. A sliding chip 34 is fixed to the upper surface of the end of the upper stile 15, which protrudes slightly from the upper surface of this end and is made of hardened metal with a rounded upper part and less wear. Further, a cam plate 35 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, and an uneven surface 37 is formed on the lower surface of the half circumference of this hole 36, and this uneven surface 37 allows the door 5 to slide to open and close. When the position of contact with the sliding tip 34 is 0 degrees,
These 0 degrees, 90 degrees, and 180 degrees are recesses with the same height, and 45
It has a continuous curved surface with convex parts at 135 degrees and 135 degrees. The cam plate 35 and the sliding tip 34 constitute an upper swing position holding section 40.

Next, an upper cam plate 47 having a downward uneven surface 46 is welded to the lower stile 17 of the door 5 at a position whose center substantially coincides with the upper pivot point 11. A guide rod 48 in the shape of a slender square bar is slidably inserted into the lower rail 41.
A bolt (not shown) is inserted vertically from the center of the lower surface of the guide rod 48, and a bolt (not shown) is inserted vertically into the center of the upper surface of the guide rod 48.
A lower cam plate 52 having an uneven surface 51 formed on the upper surface is welded upward, and furthermore, two guide wheels 54, 54 are provided on the lower surface of the guide rod 48 for smooth movement on the bottom surface of the lower rail 41. It is provided. 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, in the above configuration, the sliding opening and closing of the door 5 is the same as 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 part 40, the sliding tip 34 is in contact with the recessed part of the cam plate 35.
As the door 5 rotates, the sliding tip 34 moves to the convex portion, and the pivot shaft 28 rotates slightly around the thrust bearing 31, thereby lifting the door tip. And door 5
When the door opens 45 degrees, it touches the highest convex part and door 5 opens.
rotates while being firmly held by the hanging frame 4. At this time, the load of the door 5 is transferred to the upper rail 2 via the hanging frame 4.
A force is applied to lift the object upward.

In addition, when the lower turning position holding section 64 moves by sliding, the upper and lower cam plates 47 and 52 mesh with each other, and the guide wheels 54 and 54 move around the lower rail 4.
When the door 5 is pushed out and begins to rotate, the upper cam plate 47, which is integral with the door 5, also rotates. However, the lower cam plate 52 is connected to the guide rod 4.
8 and is prevented from turning by the lower rail 41, as the convex part of the upper cam plate 47 rides on the convex part via the inclined part of the lower cam plate 52, the lower cam plate 52 moves downward. being pushed out. Then, the lower surfaces of the guide wheels 54, 54 are connected to the lower rail 41.
Crimp it to the bottom of the

As described above, when the upper stile 15 and the hanging frame 4 and the lower stile 17 and the lower rail 41 come into pressure contact with each other when the door 5 pivots, the force of the pressing together with the load of the door 5 is applied to the hanging frame 4. On the other hand, it acts diagonally upward in FIG. At this time, the force acts on the fixed side upper rail 2 via the guide wheel 21, so the hanging frame 4
This has caused problems such as the pulley plate 20 escaping to the side as shown by the chain line in FIG. 4, or the pulley plate 20 being bent, causing a failure.

The present invention was made to solve the above problems, and by providing engaging bodies on each of the hanging frame and the upper rail support frame in the blind area, and engaging these engaging bodies with each other, This is to prevent the hanging frame from escaping to the side and the pulley plate from deforming.

Hereinafter, embodiments of the present invention will be described based on the drawings. FIG. 6 shows a first embodiment, in which an engaging body 65 made of a rail-shaped plate bent into a U-shape is fixed horizontally to the upper rail support frame 18 in the blind 1. The position of this engaging body 65 is desirably below the contact point between the upper rail 2 and the pulley 3 and as far as possible. This engaging body 65 is
It has approximately the same length as the upper rail 2. Further, an arm 66 is provided integrally with the hanging frame 4 and the pulley plate 20,
This arm 66 is integrally provided with an engaging body 67 bent into a U-shaped piece. It is desirable that one engaging body 67 is provided at approximately the same vertical position as the pulley 3, as shown in FIG. However, as shown in Figure 8,
The position may be slightly shifted from the vertical line of the pulley 3. Then, the engaging body 65 on the upper rail support frame 18 side and the engaging body 67 on the hanging frame 4 side are engaged with each other. Then, when the door 5 turns, the hanging frame 4 and pulley plate 2
0 will not escape or deform to the side.
Note that the other structures in FIG. 6 are the same as in FIG. 4.

FIG. 9 shows a second embodiment, in which the engaging body 65 on the upper rail support frame 18 side is formed as an L-shaped tray plate, and the engaging body 67 on the hanging frame 4 side is formed as a rotating body. ing.

FIG. 10 shows a third embodiment, in which the engaging bodies 65 on the upper rail support frame 18 side are composed of rotating bodies provided at regular intervals, and the engaging bodies 67 on the hanging frame 4 side are generally referred to as hanging frames 4. An example is shown in which L-shaped plates of the same length are used.

FIG. 11 shows a fourth embodiment, in which a part of the upper end of the upper rail support frame 18 is used as an engaging body 65, and the engaging body 67 on the hanging frame 4 side rotates into an arm 66 that is an extension of the pulley plate 20. An example is shown in which a body is provided.
