Description

Technical Field

[0001] The present invention relates to a fitting for moving a shoji screen by a linear motor.

Background Art

[0002] In an automatic door, a linear motor is used as a driving device for moving the door. The mover of the linear motor is connected to the door and moves relative to the stator of the linear motor when the door moves. Conventionally, there is known an automatic door in which a mover having rollers is connected to a door, and when the door moves, the rollers of the mover run on a guide rail portion (see Patent Document 1). In this conventional automatic door, the door is disposed below the mover and is vertically suspended from the mover by a moving body. The rollers of the moving body are spaced downward from a protruding piece located above and are supported from below by the guide rail portion.

[0003] As described above, in a linear motor type automatic door, the door is suspended directly below the mover of the linear motor. On the other hand, when trying to use a linear motor for a driving device of a shoji screen of a window which is a fitting, it is difficult to suspend the shoji screen directly below the mover in any of externally attached, semi-externally attached, and internally attached windows, and the shoji screen and the linear motor are arranged at a distance in the indoor-outdoor direction. Therefore, it is necessary to connect the shoji screen and the mover by a bracket extending in the indoor-outdoor direction. However, in that state, when the shoji screen is moved by the linear motor, the mover is attracted upward by the magnetic force between the stator and the mover. As a result, an upward force acts on the bracket, and the bracket is bent upward. Further, a downward force also acts on the bracket due to a restoring force. When these upward and downward forces repeatedly act on the bracket, rattling occurs in the bracket and the shoji screen. As a result, noise may occur during the movement of the shoji screen, and smooth movement of the shoji screen may be hindered.

The second shoji 3 and the screen door 4 are arranged at the outdoor side portion in the opening 21 of the frame body 20 and are also arranged at a location outside the opening 11 and the wall portion 12 of the building 10.

[0018] The building fitting 1 includes a linear motor 30 that drives the first shoji 2, a plurality of brackets 40 that connect the first shoji 2 and the linear motor 30, a plurality of rotatable guide rollers 50 connected to the linear motor 30, a plurality of rotatable lower rollers 60 located below the guide rollers 50, and a guide body 70 that guides the guide rollers 50 and the lower rollers 60. The brackets 40, the guide rollers 50, and the lower rollers 60 are provided at two locations spaced apart from each other in the moving direction K of the first shoji 2, with intervals therebetween in the moving direction K of the first shoji 2.

[0019] The linear motor 30 is a linear drive type drive device (actuator) that moves the first shoji 2 in the moving direction K. The linear motor 30 is provided on the indoor wall surface portion 13 of the wall portion 12 of the building 10 and is disposed at a position above the opening 11 of the building 10 and the first shoji 2. The first shoji 2 and the linear motor 30 are provided at different positions in the indoor-outdoor direction S and are arranged spaced apart from each other in the indoor-outdoor direction S. The linear motor 30 is provided at a position closer to the indoor side than the frame body 20 and the first shoji 2 of the building fitting 1, and the frame body 20 and the first shoji 2 of the building fitting 1 are provided at positions closer to the outdoor side than the linear motor 30.

[0020] The linear motor 30 has a stator 31 fixed directly or indirectly to the wall portion 12 of the building 10 and a mover 32 that moves relative to the stator 31. The stator 31 is an electromagnet portion having a plurality of electromagnets and is fixed to the indoor wall surface portion 13 of the wall portion 12. A gap (air gap) is provided between the stator 31 and the mover 32. The mover 32 is a permanent magnet portion having a plurality of permanent magnets and is disposed below the stator 31 without contacting the stator 31. The stator 31 and the mover 32 each extend along the moving direction K of the first shoji 2 and are arranged parallel to each other. The stator 31 is shorter than the mover 32 in the moving direction K of the first shoji 2 and is located in the central region within the moving region of the mover 32. The mover 32 is longer than the stator 31 in the moving direction K of the first shoji 2 and moves in the moving direction K of the first shoji 2 from one side position to the other side position of the stator 31 in the moving direction K of the first shoji 2.

[0021] The plurality of electromagnets of the stator 31 are provided in order along the moving direction K of the first shutter 2. The plurality of permanent magnets of the mover 32 are provided in order along the moving direction K of the first shutter 2 such that the magnetic poles of adjacent permanent magnets are opposite to each other. By a control device (not shown) that controls the movement of the linear motor 30 and the first shutter 2, the direction of the current flowing through the plurality of electromagnets of the stator 31 is changed corresponding to the position of the mover 32 (the first shutter 2), and the magnetic poles of the plurality of electromagnets of the stator 31 are respectively reversed. Thereby, a repulsive magnetic force and an attracting magnetic force are repeatedly applied in order from the electromagnet of the stator 31 to the permanent magnet of the mover 32, and a driving force for moving the mover 32 is generated. The mover 32 relatively moves with respect to the stator 31 by the driving force received from the stator 31 and moves along the stator 31.

[0022] The bracket 40 is a connecting member that connects the mover 32 of the linear motor 30 and the first shutter 2, and the mover 32, the bracket 40, and the first shutter 2 move integrally. The bracket 40 extends from the mover 32 to the first shutter 2 and is attached to the mover 32 and the first shutter 2. Further, the bracket 40 protrudes downward from the mover 32 and extends to the first shutter 2 toward the outdoor side below the linear motor 30, the guide roller 50, the guide body 70, and the lower roller 60.

[0023] The bracket 40 is attached to the mover 32 at a location on the indoor side of the opening 11 of the building 10, extends from a location on the indoor side of the opening 11 of the building 10 to a location inside the opening 11 of the building 10, and is attached to the first shutter 2 at a location inside the opening 11 of the building 10. The linear motor 30 generates a driving force in the moving direction K of the first shutter 2 and transmits the driving force to the first shutter 2 via the bracket 40 from the mover 32. Thereby, the linear motor 30 moves the first shutter 2 to one side and the other side in the moving direction K to open and close the first shutter 2.

[0024] The mover 32 has a plurality (here, two) of connecting portions 33, and the brackets 40 are attached to each of the connecting portions 33.

[0043] The lower roller 60 is sandwiched from the indoor-outdoor direction S by the lower rail portion 90, and the bracket 40 is supported at two locations, the guide roller 50 and the lower roller 60. Therefore, the bracket 40 can be stably supported, and rattling of the bracket 40 and the first sliding door 2 can be reduced. By forming the lower rail portion 90 in the lower portion 82 of the guide rail portion 80, the number of parts of the fitting 1 can be reduced, and the guide rail portion 80 and the lower rail portion 90 can be made compact.

[0044] The shaft portion 53 of the guide roller 50 is attached to the mover 32 and the bracket 40, stably supporting the mover 32 and the bracket 40 by the shaft portion 53 of the guide roller 50, and enabling the bracket 40 and the first shoji 2 to move stably in the moving direction K of the first shoji 2. The guide roller 50 is disposed below the linear motor 30, and the lower roller 60 is disposed below the guide roller 50. Therefore, the linear motor 30, the guide roller 50, and the lower roller 60 can be arranged compactly.

[0045] Note that the guide rail portion 80 and the lower rail portion 90 may be separate members and fixed to the wall portion 12 of the building 10 respectively. Further, the bracket 40 may be attached to a portion other than the upper frame 2C of the first shoji 2. The guide roller 50 and the lower roller 60 may be provided at different positions in the indoor-outdoor direction S. For example, the lower roller 60 may be provided at a position outside the room compared to the guide roller 50. The furniture may be a single-slide window having one shoji, or may be furniture other than a single-slide window (e.g., a double-slide window).

[0046] As described above, the furniture is a piece of furniture in which a shoji and a linear motor for moving the shoji are arranged separately in the indoor-outdoor direction, the linear motor having a stator fixed to a wall portion of a building and a mover moving relative to the stator, a bracket connecting the mover and the shoji, a guide roller connected to the mover, and a guide rail portion for guiding the guide roller in the moving direction of the shoji while sandwiching the guide roller from above and below in the vertical direction. The furniture is provided with the above components. Therefore, when moving the shoji by a linear motor spaced apart from the shoji in the indoor-outdoor direction, rattling of the shoji can be suppressed and the shoji can be moved smoothly.

[0047] The furniture is a lower roller located below the guide rail portion and connected to the bracket. A lower rail portion that is located below the guide rail portion and guides the lower roller in the moving direction of the shoji screen while sandwiching the lower roller from the indoor-outdoor direction, is provided. Therefore, the bracket can be stably supported and rattling of the bracket and the shoji screen can be reduced.

[0048] The lower rail portion is formed in a portion below the guide roller of the guide rail portion. Therefore, the number of parts of the fitting can be reduced, and the guide rail portion and the lower rail portion can be made compact.

[0049] The guide roller is located on the axis of the guide roller and has a shaft portion attached to the mover and the bracket. Therefore, the mover and the bracket can be stably supported by the shaft portion of the guide roller, and the bracket and the shoji screen can be stably moved in the moving direction of the shoji screen.

[0050] The guide roller is disposed below the linear motor, The lower roller is disposed below the guide roller. Therefore, the linear motor, the guide roller, and the lower roller can be compactly arranged.
