Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interlocking opening/closing device for building entrances, windows, furniture, and the like.

In conventional interlocking opening/closing devices of this kind, such as sliding doors, the doors move only in a straight line, so when the doors are closed, a step equal to the thickness of the door is created between adjacent doors. This level difference is not particularly suitable for Western-style buildings, and it also has the disadvantage that the indoor area in a fully closed state is small, regardless of whether it is a Western-style building or a Japanese-style building.

The present invention has been made in view of these points, and by making two adjacent doors flush on the same surface when the doors are closed, it increases the indoor area when the doors are fully closed. The purpose is to provide an interlocking opening/closing device with a simple appearance suitable for Western-style architecture and furniture.

Therefore, the feature of the present invention is that one door moves in the indoor/outdoor direction on the entrance/exit side of the other adjacent door, so that when the two doors are open, they overlap, and when they are fully closed, they are on the same plane. The one door is guided to run along a guide rail portion whose tip end on the entrance side is curved in a substantially arc shape in plan view, and while both doors run in the same direction, one door is guided by the other door. The two doors are interlocked by a differential interlocking mechanism so that the two doors can move a longer distance than the two doors.

EMBODIMENT OF THE INVENTION Hereinafter, the present invention will be explained in detail based on drawings showing examples.

In Figures 1, 2, and 3, 1 is a frame attached to the inner circumferential side of the building opening, 2 is an upper frame of the frame 1, 3 is a lower frame thereof, and 4 is a storage fixing part. and door pockets, fixed doors, fixed walls,
It consists of a fixed plate, etc., and the example shown in the figure shows a fixed door. Reference numerals 5 and 6 indicate two doors that are hung from the running rails 7 and 8 of the upper frame 2 via removable hanging rollers 9, and 5 indicates the door on the indoor side A, and 6 indicates the door on the indoor side A. It shows the door on the outside B. The hanging roller 9 of the door 6 on the indoor side B is pivotally supported near the left and right ends of a widthwise protrusion 10 that is integrally provided on the upper surface of the door 6, and the hanging roller 9 of the door 5 on the indoor side A is It is attached via support arms 12 to the left and right sides of a widthwise protrusion 11 which is also integrally erected on the upper surface of the door 5. Specifically, as shown in FIG. 4 and FIG.
One end is pivotally connected to the fixed connecting member 14 by a pivot 15, and a roller mounting member 16 having substantially the same shape as the connecting member 14 is pivotally connected to the other end by the pivot 15. The hanging roller 9 is pivotally connected to the mounting member 16 . Thus, when the door 5 is suspended from the traveling rail section 7, it forms a parallel link mechanism with the rail section 7 and the support arm 12, and can move toward and away from the rail section 7 in parallel. Note that the vertical dimensions of the support arm 12, the connecting member 14, and the mounting member 16 must be set to a size sufficient to support the door 5, and for that reason, the support arm 12 is formed into a plate shape as shown in the figure. It is preferable to use it in an upright position.

The two doors 5 and 6 attached to the upper frame 2 in this way run in the same direction and are differentiated so that the door 5 on the indoor side A moves a longer distance than the door 6 on the outdoor side B. Dynamic interlocking mechanism 17
It is linked with. The differential interlocking mechanism 17 includes a rotor 18 made of a gear rotatably pivotally attached to the entrance/exit side E end of the upper surface of the door 6 on the outdoor side B, and a protrusion 11 on the door 5 on the indoor side A. A linear engagement part 19 consisting of a rank is attached and engages with the rotor 18, and a rotor 18 is attached to the inside of the outdoor side B hanging piece 20 of the upper frame 2 in substantially correspondence with the door 6 in the fully closed state. and a linear meshing portion 21 that meshes with the shaft. In addition, in the linear engagement part 19 of the door 5, the ends of the four storage fixing parts are bent toward the indoor side A at an angle θ as shown in FIG. It is said that And door 5 is
The guide rails 22, 23, 27, and 28 of the upper frame 2 and lower frame 3 are arranged so that they are flush with the door 6 in the fully closed state as shown in FIG. The journey will be guided. That is, near the left and right ends of the protrusion 11 of the door 5, a guide roller 24 located on the indoor side A and a guide roller 25 located on the outdoor side are rotatably attached via L-shaped fittings 26, respectively. A guide roller 29 located closer to the indoor side A and a guide roller 30 located closer to the outdoor side B are rotatably attached near the left and right ends of the lower surface of the door 5, respectively. fit into the respective guide rail parts 22, 23, 27, 28.

Each of the guide rail parts 22, 23, 27, 28 is formed such that the end on the entrance/exit side E is curved in a substantially arc shape toward the outdoor side B, and each guide roller 24.25°2 is formed at the tip end thereof.
When 9 and 30 are positioned, doors 5 and 6 are fully closed and on the same plane. In this fully closed state, the rotor 18 meshes with the linear meshing part 21 of the door 6, and also meshes with the linear meshing part 19 of the door 5 at its bent end.

When the door 5 attempts to open in the direction of arrow F from the fully closed state shown in FIG. Due to this pressure, the rotor 18 rolls on the linear meshing part 21, and the door 6 starts moving as shown by arrow G, and at the same time, the door 5 meshes with the rotor 18 and the guide rail parts 22, 23, 27. 28, it starts to move in the direction of the room in a tomographic manner as shown by arrow H. After that, the guide roller 24.25.29.30 moves the guide rail part 22.23.2
7. When the linear part of 28 is reached, the linear meshing part 19
meshes with the rotor 18 at its straight part,
Further, it meshes with the rotor 18 on the opposite side of the linear meshing portion 21 by 180°. That is, the doors 5 and 6 run in the same direction, and the rotor 18 of the door 5 is fixed to the linear meshing part 2.
The distance traveled is greater than the net movement amount of the door 6 due to the transfer of the door 6, and the ratio of the movement distance is about 2:1.

In the fully closed state, the housing and fixing portion 4 are completely overlapped as shown in FIG. The width of the door 5 is made slightly longer than the width of the door 6, so that the end of the door 5 on the entrance side E protrudes beyond the storage fixing part 4 and the door 6 in the fully closed state shown in FIG. If this is done, the door 5 can be opened and closed easily, and there is no risk of fingers being jammed.

Further, the planar shapes of the mutually opposing lateral end surfaces (vertical stile end surfaces) of the doors 5 and 6 are inclined, and as shown in FIG. Engagement protrusion 3
1 and an engagement recess 32 on the outdoor side B,
Engagement recesses 3 corresponding to the engagement protrusions 31 and 32 of the door 5 are provided on the indoor side A and the outdoor side B of the inclined end portion 6a of the door 6, respectively.
3 and the engagement protrusion 34, the door 6 can be reliably held in the closed state simply by locking the door 5 vertically on the frame 1, and it is also preferable in terms of watertightness. Furthermore, if a vertical groove 35 is formed approximately in the center of the inclined ends 5a, 6a and a sealing material 36 is attached to the vertical groove 35 as shown in FIG. 8, more complete watertightness can be achieved. .

Note that guide rollers 37 are also attached to the left and right sides of the lower surface of the door 6, and are fitted into the linear guide rail portions 38 of the lower frame 3. Further, a recess 39 is formed below the door 6, substantially corresponding to the rotor 18, and a guide roller 40 is attached to the recess 39, which is brought into contact with the outdoor side B side of the lower stile of the door 5 and transferred. ing. This guide roller 40 has the advantage that the door 5 can be smoothly guided in moving relative to the door 6. 41 is a plastic sliding member attached to the indoor side A side of the protrusion 10 of the door 6, and comes into contact with the inner hanging piece 42 of the upper frame 2.

Reference numeral 43 denotes a storage wall on the indoor side A of the storage fixing section 4, which is attached to a wall or pillar of a building with a hinge 44 so that it can swing open and close as shown by the arrow R, and has an L-shaped bend at the tip edge. Section 43
It has a. 1. By opening this storage wall 43, the doors 5 and 6 can be repaired easily. Reference numeral 45 denotes a hidden plate that is swingably attached to the inside of the bent end portion 43a of the storage wall 43 by a hinge 46, and is constantly urged in the direction of the arrow by a resilient member 47 as shown in FIG. And storage wall 4
Further swinging is prevented by the bent portion 43a so as to be substantially perpendicular to 3. Also, at the tip of the hidden plate 45, there are a plurality of small rollers 48 (31 in FIG. 9).
・is pivotally mounted for free rotation. Therefore, in the state shown in FIG. 1 in which the door 5 is pulled out from the storage fixing part 4, the hidden plate 45
closes the gap between the storage wall 43 and the door 6 to hide the inside of the storage. Further, when the door 5 moves into the storage fixing part 4, the hidden plate 45 is swung inward against the resilient force of the door 5, allowing the door 5 to enter as shown in FIG. and,
The small rollers 48 of the hidden plate 45 prevent the door 5 from being scratched, and the door 5 can be smoothly moved from side to side. Furthermore, a small roller 49 is rotatably attached to the tip of the inclined end 5a of the door 5, as shown in FIGS. 2 and 10, and the hidden plate 45 is moved inside by the small roller 49. sway to. Therefore, the hidden plate 45 has a small roller 49
This prevents scratches and allows for smooth rocking.

Further, the door 5 is prevented from being damaged at the tip of the inclined end portion 5a.

In addition, in this embodiment, the upper frame 2 is attached to the base member 2A that is attached to the building opening side and from which the door 6 on the outdoor side B is suspended, and the upper frame 2 is attached to and removed from the indoor side A with respect to the base member 2A. and a separation member 2B on which the door 5 on the indoor side A is suspended, and the door 5 on the indoor side A is suspended from the frame 1 while the door 5 and the door 6 are separated.
It is designed to be able to be assembled and removed from the ground, reducing work effort. That is, the separation member 2B has the running rail part 7 and the guide rail part 22, 23 for the door 5, and further has the interior side A.
If an inner horizontal wall portion 51 is formed integrally or with a separate member over the entire length of the lower end edge of the hanging piece 50, as shown by the imaginary line,
This is preferable because the internal structure of the mold material cannot be seen when looking upward.

FIG. 11 shows another embodiment of the door 50 travel guide mechanism on the indoor side A. In this example, the guide rollers 24.25
A left-right and left-separable suspension roller 9 is provided coaxially with the suspension roller 9, and the suspension roller 9 is also rotatable around a support shaft 52. The traveling rail portion 7.7 is formed along the guide rail portion 22.23, and therefore has a substantially arc-shaped curved portion like the rail portion 22.23, but the hanging roller 9 rotates around the support shaft 52. By being movable, it is possible to run on this running rail portion 7.7.

According to this embodiment, a support arm 12, a connecting member 14 and a mounting member 1 for supporting the door 5 as in the previous embodiment are used.
6 is unnecessary, the support structure can be simplified and the support strength can be increased.

The present invention is not limited to the embodiments described above; for example, the rotor 18 and linear meshing portions 19, 21 of the differential interlocking mechanism 17 may be constructed with sprockets and chains instead of gears and ranks. be. It is also preferable to use two sets of sliding doors consisting of door 5 and door 6 in one building opening so that they open and close in opposite directions to form a double sliding door. The present invention can be widely applied to sliding doors of entrances and bathrooms, opening/closing parts of various types of furniture such as bookshelves, and even windows.

The present invention has effectively achieved its intended purpose with the configuration detailed above. In particular, since the adjacent doors 5 and 6 are constructed so as to be on the same plane in the fully closed state, the appearance is simple and is particularly suitable for Western-style architecture, as well as for opening/closing devices for various types of furniture. In addition, when the vehicle is fully closed, the interior of the vehicle feels spacious (substantially the interior area becomes larger), resulting in better comfort.

Furthermore, since the doors 5 and 6 are interlocked by the differential interlocking mechanism 17, it is only necessary to open and close one door 5, and the opening and closing operations can be performed easily.
