The rolling elements 29d on both sides in the door thickness direction may be provided at a plurality of locations at intervals in the door width direction of the guide main body 29c.

Further, a drive mechanism 20 is connected to the first guided member 29A, which is one of both sides in the door width direction, although details will be described later. That is, the first guided member 29A is slid in the door width direction by the drive mechanism 20, and the second guided member 29B on the other side, which is not connected to the drive mechanism 20, is subordinately slid in the door width direction. ..
The first guided member 29A and the second guided member 29B are not limited to those having the above-mentioned configuration, but have an appropriate configuration according to the upper rail 10 described later. May be good.
Further, the lower end portion of the sliding door panel 9 may be provided with a guide groove or the like into which a lower end guide member such as a guide pin provided on the floor side is inserted.

As shown in FIG. 1 (b), the upper rail 10 has the longest length L1 which is approximately twice the maximum door width W1 of the sliding door panel 9. In the present embodiment, the upper rail 10 constitutes the longest upper rail 10 having the longest length L1, and the drive mechanism 20 is fixed to the first half portion 10A on one side in the longitudinal direction thereof. There is. With such a configuration, when the sliding door panel 9 has a maximum door width W1 as in the present embodiment, the first guided member 29A is slid on the first half portion 10A of the longest upper rail 10. The sliding door panel 9 can be opened and closed by sliding the second guided member 29B on the second half portion 10B side of the longest upper rail 10. When the door width of the sliding door panel 9 is smaller than the maximum door width W1, the length of the upper rail 10 is set to be approximately twice the length of the door width, for example, the second half portion 10B side. A common drive mechanism 20 can be applied by making adjustments such as cutting or shortening in advance.

That is, even if the dimension of the second half portion 10B side of the longest upper rail 10 is shortened, the drive mechanism 20 does not affect the fixed first half portion 10A side, and the drive mechanism 20 There is no need to change the installation position. Thereby, the common drive mechanism 20 can be applied from the sliding door panel 9 having the maximum door width W1 to the sliding door panel 9A (see FIG. 10) having a door width (minimum door width) W2 of about 1/2 of the maximum door width W1. , Versatility can be improved. In other words, the dimension along the rail longitudinal direction (door width direction) of the drive mechanism 20 is approximately twice or less the dimension of the minimum door width W2 so that the sliding door panel 9A having the minimum door width W2 can be opened and closed. ..
That is, in the door opening / closing device 1A according to the modified example shown in FIGS. 10A and 10B, the sliding door panel 9A in which the door width W2 is approximately ½ of the sliding door panel 9 having the maximum door width W1 described above. It is configured to open and close. The length L2 of the upper rail 10C of the door opening / closing device 1A is approximately twice the door width W2 of the sliding door panel 9A, and is approximately ½ of the length L1 of the longest upper rail 10 described above. .. In other words, the length L2 of the upper rail 10C is substantially the same as the length of the first half portion 10A of the longest upper rail 10 described above.

Since the other configurations of the door opening / closing device 1A according to the modified example have the same configurations as those of the door opening / closing device 1 shown in FIG. 1 and the like, the same reference numerals are given and the description thereof will be omitted.
Further, in each example, the lengths L1 and L2 of the upper rails 10 and 10C are smaller than twice the door widths W1 and W2. The lengths L1 and L2 of the upper rails 10 and 10C are the overlapping dimensions of the door tail side end of the closed sliding door panel 9, 9A and the neutral 6 (sleeve wall), and the sliding door panel 9, 9A in the fully open state. The dimensions may be appropriate according to the unremaining dimensions and the like. In other words, the lengths L1 and L2 of the upper rails 10 and 10C are abbreviated as the dimensions obtained by subtracting the dimensions obtained by doubling the above-mentioned overlapping dimensions from the dimensions obtained by doubling the door widths W1 and W2 of the sliding door panels 9 and 9A. It may have the same dimensions.

Further, in the present embodiment, the second half portion 10B on the other side in the longitudinal direction of the longest upper rail 10 is cuttable. With such a configuration, when the door width W2 of the sliding door panel 9A is smaller than the maximum door width W1, the second half portion 10B side is cut so as to be approximately twice as long as the door width W2. By doing so, the upper rail 10C having a length L2 that can guide the sliding door panel 9A can be obtained. As a result, for example, it is possible to cut the second half portion 10B side in a state where the drive mechanism 20 is attached to the first half portion 10A, and it is possible to easily deal with it even after factory shipment. Further, the upper rail 10 may be made of a metal having at least the second half portion 10B having a uniform cross-sectional shape over the entire length and can be cut by an appropriate cutting tool.

Further, as shown in FIG. 2, the upper rail 10 is provided with a guide groove 11 for receiving the guided member 29 (the first guided member 29A and the second guided member 29B) so as to open downward. .. The guide groove 11 is provided so as to extend over the entire length of the upper rail 10. The guide body 29c of the guided member 29 is inserted into the guide groove 11 and guided.

The guide pieces 13a and 13a extend from the lower end of the rail in the direction facing each other. Further, the upper rail 10 includes protrusions 14 and 14 on both sides provided so as to project upward from both side edges in the groove width direction on the upper surface side of the groove bottom plate-shaped portion 12.

The leading ends of the guide pieces 13a and 13a on both sides in the extending direction are provided with ridges protruding upward so as to extend over the entire length of the upper rail 10. An annular groove provided on the outer peripheral surface of the rolling elements 29d and 29d of the guided member 29 engages with the ridges of the guide pieces 13a and 13a, and rolls along the ridges of the guide pieces 13a and 13a. The moving bodies 29d and 29d run. The upper rail 10 is not limited to the one having the guide pieces 13a and 13a on which the rolling elements 29d and 29d provided at intervals on both sides in the door thickness direction run. The upper rail 10 may be provided with, for example, one guide piece portion on which the rolling element 29d provided only on one side in the door thickness direction of the guided member 29 is held so as to be hooked. , It may have various configurations.

As shown in FIGS. 2 to 5, the drive mechanism 20 is fixed on the groove bottom plate-shaped portion 12 of the upper rail 10 described above. With such a configuration, the upper rail 10 is fixed to a fixing target such as the upper frame 3 of the door frame 2 on which the sliding door panel 9 is built in a state where the drive mechanism 20 is integrated with the upper rail 10. Can be done. Further, for example, as compared with the case where the drive mechanism 20 is fixed to the side plate-shaped portion 13 or the like of the upper rail 10, it is possible to reduce the size of the dimensions along the door thickness direction.
As shown in FIGS. 3 and 4, the drive mechanism 20 comprises a first driven rotating wheel 21 constituting a first rotating wheel and a second driven rotating vehicle constituting a second rotating wheel provided at positions separated in the door width direction. It is equipped with a rotating wheel 25.

The first driven rotary wheel 21 is provided so as to be located at the first end portion 10a on one side in the longitudinal direction of the first half portion 10A of the longest upper rail 10. The second driven rotary wheel 25 is provided so as to be located at the second end portion 10b on the other side in the longitudinal direction of the first half portion 10A of the longest upper rail 10. With such a configuration, the first guided member 29A can be slid over the substantially overall length of the first half portion 10A of the longest upper rail 10 by the string-shaped transmission body 28 wound around them. Further, even when applied to different door widths W1 and W2, the application shall be applied without changing the installation position of the first driven rotating wheel 21 and the second driven rotating wheel 25 and the length of the string-shaped transmission body 28. Can be done.

The drive unit 30 is provided so as to be located between the first driven rotary wheel 21 and the second driven rotary wheel 25 and above the upper rail 10, and drives the string-shaped transmission body 28. It includes a drive rotating wheel 31 for transmission and a motor 35 for rotating the drive rotating wheel 31. With such a configuration, when the drive rotating wheel 31 is rotated by the motor 35, the first guided member 29A connected to the string-shaped transmission body 28 is moved in the door width direction to open and close the sliding door panel 9. be able to. Further, as compared with the case where the drive rotating wheel 31 and the motor 35 are provided at one end in the door width direction, the dimensions along the door width direction can be made more compact. Further, as compared with the case where the drive rotating wheel 31 is provided on one side of the upper rail 10 in the door thickness direction, the dimensions along the door thickness direction can be made more compact. As a result, it is possible to install the door frame 2 on the same level as the door frame of the sliding door device installed in a general building such as a house. Further, for example, it can be installed on the existing door frame 2 and can be applied not only at the time of new construction but also at the time of remodeling or remodeling. As a result, sliding door panels installed in the rooms of existing detached houses, apartment houses and other general houses, accommodation facilities, medical facilities, welfare facilities and other public facilities, offices and other commercial facilities, and various stores. It can be suitably used as a door opening / closing device 1 for opening / closing 9. Further, since the door opening / closing device 1 is compact, the sliding door panel 9 can function as an automatic door, but even if it is installed as an indoor sliding door, it is possible to reduce the discomfort (noise) in appearance. , Can be suitably used for indoor use.

In the first driven wheel 21 and the second driven wheel 25, the first driven axle 22 and the second driven axle 26, which are the respective axes, are parallel to each other. Further, the first driven axle 22 and the second driven axle 26 are provided so as to intersect the axial direction of the drive axle 32 of the drive rotating wheel 31 provided so that the axial direction is the door height direction. With such a configuration, the axial direction of the drive rotating wheel 31 is set to the door thickness direction, and the dimensions along the door thickness direction are reduced as compared with the case where the motor 35 is provided adjacent to the door thickness direction. Can be planned. Further, the portion of the string-shaped transmission body 28 connected to the first guided member 29A and the portion to which the drive is transmitted to the drive rotating wheel 31 can be arranged vertically. As a result, it is possible to more effectively reduce the size along the door thickness direction as compared with the case where the axial direction of the first driven rotating wheel 21 and the second driven rotating wheel 25 is the door height direction.

Further, as shown in FIG. 7, the motor 35 is arranged on one side of the drive rotary wheel 31 in the door width direction so that the axial direction of the output shaft 36 is the door width direction, and the motor 35 is driven and rotated via the gears 33 and 37. It is configured to rotate the car 31. With such a configuration, it is possible to reduce the size along the door height direction as compared with the case where the motor 35 is provided so that the axial direction of the output shaft 36 is the door height direction. The specific configuration of the drive unit 30 including the drive rotary wheel 31 and the motor 35 will be described later.

A string-shaped transmission body 28 is wound around the first driven rotary wheel 21 and the second driven rotary wheel 25 in a parallel hanging manner (see FIG. 4). In the string-shaped transmission body 28, the lower displacement portion 28b is connected to the first guided member 29A and is displaced in the door width direction, and the upper displacement portion 28a is displaced to the opposite side in the door width direction from the lower displacement portion 28b.
