Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a novel device that automatically opens and closes a wall that separates a building from the outside and inside or between rooms.

[Conventional technology]

As a kind of building in recent years, for example, many buildings and the like, in which most of the first floor is designed as one large floor, have been constructed. In order to give a high-grade image to this type of building, a plurality of glass plates having a large height dimension and a large width dimension are fixedly arranged in parallel as a wall partitioning the first floor from the outside. In general, small-sized entrance doors are installed at appropriate places on the wall.

[Problems to be solved by the invention]

By the way, in recent years, there has been a demand to temporarily use the large floor of the first floor for various operations in addition to the daily lobby floor. For example, "I want to hold an event where many people gather.", "I want to make the opening large enough to create an indoor park where natural outside air can enter.", "I want to put in a large exhibit and hold an exhibition." New demands have emerged.

In order to solve the above requirements, a large outside door is required. However, there are various restrictions on the outside entrance doors on the first floor of the building (entrance), and the conventional technology has not been able to meet the above requirements because it has not been solved. Not enough. For example, "The installation of a large number of small doorways impairs the architectural aesthetics.""Since the automatic door provided on the wall is a cantilever, its size is structurally limited due to wind resistance and its own weight." A large door is an automatic drawer door for operation, but the fixed wall (glass) and the movable door (glass door) do not form the same plane, which detracts from the architectural aesthetics. "

Accordingly, the present invention has been made as a technical problem to provide a device having a novel configuration capable of automatically and smoothly opening and closing a large entrance door which does not impair the architectural beauty.

[Means for solving the problem]

The specific means for achieving the above technical problem is that a wall partitioning the exterior and the interior of the building or between the chambers is composed of an immovable wall and a movable wall. A first drive for arranging the body so as to be able to take a fully closed position where it is flush with an adjacent immovable wall and a fully open position where it is superimposed and moving the movable wall in the retraction direction; In a wall opening / closing device for a building, comprising a mechanism and a second drive mechanism for moving the movable wall in the opening / closing direction, one end of the movable wall is guided from the fully closed position to the take-out direction when the movable wall is opened. While the movable wall body is in the inclined state, at the time of the closing operation of the movable wall body has a guide rail that guides one end of the movable wall body in the retracting direction from the inclined state and is positioned in the flush state, The first drive mechanism is A coupling mechanism to the Dokabetai movable suspension to the support and brought out pull direction to said second drive mechanism, a driving unit for moving one end brought out pulling direction of the movable wall, there is to made of.

[Action]

According to the above-described means, in normal times, the movable wall is held at the fully closed position and held so as to be flush with the immovable wall, so that no gap is formed between the two walls and Steps should not be formed between the walls of the body, thereby ensuring that the function as the wall of the building is possessed and the appearance is not impaired. Further, when a large opening is required, the one end side of the movable wall is moved by a predetermined dimension in the take-out direction by the operation of the first drive mechanism, and the movable wall is inclined. After that, the movable wall body in the inclined state is moved to the fully open position by the operation of the second drive mechanism, and overlaps with the adjacent immovable wall body. During the movement of the movable wall in the opening direction, the movable wall gradually becomes parallel to the immovable wall from the inclined state due to the guide action of the guide rail, and becomes immovable in a state parallel to the immovable wall in the fully open position. Polymerizes with walls. Since the movable wall body is opened as a sliding door, the self-suspended structure prevents deflection of its own weight, the upper and lower rails prevent overturning, such as wind pressure, and a uniform load on the mechanism. As a result, the large movable wall can be smoothly operated, and an extremely large entrance / exit opening corresponding to the size is formed, so that a large number of people, large articles, and a large amount of outside air can enter and exit smoothly. Further, when returning from the fully open position to the fully closed position, the movable wall body is moved in the closing direction by the operation of the second drive mechanism, and then the one end side of the movable wall body is operated by the operation of the first drive mechanism. Is moved in the retracting direction so that the movable wall and the immovable wall are brought into a flush state again.

A door body 9 of one movable wall 2a is fixed via a connecting member 15 at a predetermined position on a tension side 13a of the winding transmission member 13. Further, a door body 9 of the other movable wall 2a is fixed via a connecting member 15 at a predetermined position on the slack side 13b of the winding transmission member 13. Accordingly, with the rotation of the door engine 11, the two movable walls 2a, 2a move in the directions of approaching and separating from each other. At the upper and lower ends of the door body 9, additional rollers 19 and 20 that move along groove rails 17 and 18 fixed to the blind 6 are attached.

The connecting mechanism 10 includes a first link member 21a having one end fixed to the movable wall 2a, a second link member 21b having one end fixed to the door body 9, and a third link member disposed between the two. The movable wall 2a is suspended from and supported by the door body 9 via the coupling mechanism 10. The movable wall 2a is rotatably connected to the door body 9 via two support shafts 22 and 23. Further, upper guides 24, 24 and lower guides 25, 25 are attached to the upper end and the lower end of the movable wall 2a, and the upper guides 24, 24 are attached to an upper guide rail 26 fixedly attached to the blind 6.

Shows the upper guide rail 26, while the left half shows the lower guide rail 27, and the two guide rails 26, 27
Each has a dimension over the entire length in the width direction of the two movable wall bodies 2a, 2a and the immovable wall bodies 2b, 2b, and their shapes are bilaterally symmetric. Further, both of the guide rails 26 and 27 are linear rail portions 26a and 27a extending linearly along one side of the immovable wall 2b located on both sides of the movable wall 2a,
The linear rails 26a, 27a comprise inclined rails 26b, 27b which are inclined toward the center line in the thickness direction of the stationary wall 2b from the linear rails 26a, 27a. The bulging rail portions 26c, 27c bulging toward the center line in the thickness direction of the immobile wall 2b are formed (see FIGS. 8 and 9). When the movable wall 2a is in the fully closed position, that is, in the state shown by the solid line in FIG. 6, the corresponding one upper guide 24 and one lower guide 25 are positioned on the bulging rail portions 26c, 27c. The position is set as follows. Further, as shown in FIGS. 2 to 4, an intermediate guide rail 28 extending in the width direction is fixedly provided at an intermediate portion in the height direction on one side of the movable wall 2a. An intermediate guide 29 is engaged with the rail 28, and the intermediate guide 29 is connected to an electric cylinder 31 via an arm mechanism 30. The arm mechanism 30 and the electric cylinder 31 constitute a driving unit that takes out one end of the movable wall 2a and moves it in the retraction direction. The arm mechanism 30,
One end has the intermediate guide 29 and the other end is a cylindrical sleeve.
A first arm 33 fixed to 32; and a second arm 34, one end of which is rotatably connected to the tip of the retraction rod 31a of the electric cylinder 31 and the other end of which is fixed to the cylindrical sleeve 32. The cylindrical sleeve 32 is rotatably fitted and held on a fixed support shaft 36 which is fixed through a holding plate 35 in a seamless manner. Therefore, the first arm 33 and the second arm 34 are integrally rotated around the fixed support shaft 36 by the forward / backward movement of the rod 31a of the electric cylinder 31.

 Next, the operation of the above embodiment will be described.

First, assuming that the movable walls 2a, 2a are in the fully open position as shown by the dashed line in FIG. 6 and are in a superposed state with the adjacent immovable walls 2b, 2b, the immovable wall 2b By appropriately operating the control operation box 37 (refer to FIG. 5) provided at the appropriate position, the door engine 11 is driven to move the movable walls 2a, 2a through the door bodies 9, 9 in the closing direction to approach each other. Move. In this case, the movable wall 2a is guided and moved by the upper guide rail 26 and the lower guide rail 27, and the two guide rails 26, 27 have inclined rail portions 26b, 27b.
Is formed, the movable walls 2a, 2a are inclined when they reach the moving end in the closing direction. Then, in such a state, the extension rod 31 of the electric cylinder 31 shown in FIG.
a moves forward, the first arm 3 of the arm mechanism 30 is moved.
The third and second arms 34 rotate about the fixed support shaft 36, and the accompanying movement of the intermediate guide 29 causes the intermediate guide rail 28 and the movable wall 2a to move in the retracting direction. Thereby, the upper guide 24 and the lower guide attached to the movable wall 2a
25 changes from the state shown by the solid line to the state shown by the chain line in FIGS. As a result, the movable walls 2a, 2a move to the fully closed position shown by the solid line in FIG. 6 and become flush with the immovable walls 2b, 2b. At this time, the movable walls 2a are connected. Since the movable body 2a is movably held by the door body 9 via the mechanism 10, the door body 9 does not move even if the movable wall 2a moves in the retracting direction. The movable wall 2a that has completed the movement in this manner does not protrude with respect to the immovable wall 2b, that is, there is no step between the movable wall 2a and the immovable wall 2b. Also, as shown in FIG. 10, the movable wall 2a and the immobile wall 2b are securely sealed by the seal member 38, so that the movable wall 2a functions as well as a normal wall. It becomes possible to secure architectural aesthetics.

On the other hand, when a large opening is required on the internal floor of the building 1, the electric cylinder 31 is first actuated to move the movable wall 2a in the take-out direction. To move the movable wall 2a in the opening direction,
When it reaches the opening direction moving end, it is fully opened as shown by a chain line in FIG. Thereby, an extremely large entrance / exit portion corresponding to the total area of the two movable wall bodies 2a, 2a is secured. Then, when the large opening becomes unnecessary, the above-described closing operation is performed again, so that the movable wall 2a functions as a normal wall again.

In this case, when the electric cylinder 31 is actuated to move the movable wall 2a in the pull-out / pull-out direction, the third link member 21c of the coupling mechanism 10 shown in FIG. As a result, the movable wall 2a moves in an inclined manner. However, as shown in FIG. 10, the movable wall 2a is easily moved into the gap Y between the movable wall 2a and the immovable wall 2b. Since the elastically deformable seal member 38 is interposed, the movement of the movable wall 2a in the inclined direction is not hindered.

In the above embodiment, the present invention is applied to a wall that separates the outside and the inside of the building.However, the present invention is not limited to this. It is needless to say that the present invention can be similarly applied to a wall partitioning a wall.

Further, in the above embodiment, the movable wall body is opened and closed by appropriately operating the control operation box 37 provided at an appropriate position of the immovable wall body.In addition, for example, a separately provided management room is provided. An operating device may be installed, and the movable wall may be opened and closed by remote control from this management room.

[Effect of the invention]

As described above, according to the present invention, the wall of a building is composed of an immovable wall and a movable wall, and the movable wall is smoothly operated as a sliding door by the operation of the first drive mechanism and the second drive mechanism. Since the opening and closing operation is adopted, the movable wall and the immovable wall are normally flush with each other without any gap to form an integrated wall, thereby ensuring an architectural aesthetic. When a large opening is required, the movable wall is superimposed on the adjacent immovable wall to be in a fully opened state, so that an extremely large entrance / exit opening is formed. It is possible to smoothly enter and exit. In addition, since the opening and closing operation of the movable wall body is automatically performed by the operation of the first and second drive mechanisms, even if the movable wall body is extremely large, compared with the case of manual operation, The opening and closing operation is easily performed. Further, since the movable wall body is configured to be opened and closed as a sliding door, for example, as in the case where the movable wall body is opened and closed as a hinged door, the space for the opening and closing operation is increased, and the tip of the movable wall body drips due to its own weight. Is effectively avoided. Further, when the movable wall body is opened, one end of the movable wall body in the fully closed position is guided in the take-out direction so that the movable wall body is inclined, and when the movable wall body is closed, the one end is moved in the retracting direction. It has a guide rail for guiding, and one end of the movable wall body is driven by the first drive mechanism in the pull-out and pull-in direction by a single drive section, so that the configuration of the first drive mechanism is simplified. be able to.
