Further, the first guided member 29A and the second guided member 29B include a support shaft 29b provided to protrude upward from the attached portion 29a, and a guide body 29c fixed to the support shaft 29b upper end. The guide main body 29c is provided with a rotating body 29d that slides on the guide piece 13a of the upper rail 10 to be described later. In the illustrated example, a rotating body 29d that rotates around an axis in the door thickness direction is provided on each side of the guide body 29c on both sides in the door thickness direction. In addition, the rotating bodies 29d on both sides in the door thickness direction may be configured to be provided at a plurality of places with intervals in the door width direction of the guide body 29c.

In addition, the drive mechanism 20 is connected to the 1st guided member 29A which is one of the two sides in the door width direction, and the details thereof will be described later. That is, the first guided member 29A is slid in the door width direction by the driving mechanism 20, and the second guided member 29B not connected to the other side of the driving mechanism 20 can be said to be driven slid across the width of the door. In addition, as these 1st to-be-guided member 29A and 2nd to-be-guided member 29B, it is not limited to what is comprised as mentioned above, It can also be comprised suitably according to the upper rail 10 mentioned later. Furthermore, a guide groove or the like may be provided at the lower end portion of the sliding door flap 9 for insertion of a lower end guide member such as a guide pin or the like provided on the floor side.

As shown in FIG. 1( b ), the upper rail 10 has a longest length L1 which is approximately twice the maximum door width W1 of the sliding door flap 9 . In this embodiment, the upper rail 10 is the longest upper rail 10 with the longest length L1, and the drive mechanism 20 is fixed to the first half 10A on one side in the longitudinal direction. With this configuration, as in the present embodiment, when the sliding door flap 9 is the largest door width W1, the first half portion 10A of the longest upper rail 10 will slide the first guided member 29A; On the side of the second half portion 10B of the longest upper rail 10, the second guided member 29B is slid; thereby, the sliding door flap 9 can be opened and closed. Furthermore, in the case where the door width of the sliding door panel 9 is smaller than the maximum door width W1, in order to make the length of the upper rail 10 approximately twice the length of the door width, for example, by cutting the second half 10B side. , or preliminarily shortened, etc. to adjust, the common drive mechanism 20 can be applied.

That is to say, even if the dimension of the second half 10B side of the longest upper rail 10 is shortened, it will not affect the first half 10A side to which the driving mechanism 20 is fixed; moreover, the driving mechanism 20 will not be changed. the need to set the location and so on. Thereby, the common drive mechanism 20 can be set from the sliding door flap 9 of the maximum door width W1 to the sliding door flap 9A of the door width (minimum door width) W2 of approximately 1/2 (refer to FIG. 10 ). , are applicable, and improve the versatility. In other words, the dimension along the rail longitudinal direction (door width direction) of the drive mechanism 20 is set to be less than or equal to approximately twice the minimum door width W2, so that the sliding door flap 9A of the minimum door width W2 can be opened and closed . That is, the door opening/closing device 1A according to the modification example shown in FIGS. 10( a ) and ( b ) is configured such that the door width W2 is approximately 1/1 of the sliding door flap 9 of the maximum door width W1 2 left and right sliding door flaps 9A are opened and closed. The length L2 of the upper rail 10C of the door opening and closing device 1A is approximately twice the door width W2 of the sliding door flap 9A, and approximately 1/2 of the length L1 of the longest upper rail 10 described above. In other words, the length L2 of the upper rail 10C is set to be substantially the same as the length of the first half 10A of the longest upper rail 10 .

In addition, since the other structure in the door opening/closing apparatus 1A which concerns on a modification is the same structure as the door opening/closing apparatus 1 shown in FIG. 1 etc., the same code|symbol is attached and description is abbreviate|omitted. In addition, in each example, the lengths L1 and L2 of the upper rails 10 and 10C are set to be smaller than "twice the door widths W1 and W2". The lengths L1 and L2 of the upper rails 10 and 10C only need to be in accordance with the overlapping dimension of the rear end of the door flaps 9 and 9A in the closed state and the middle door pillar 6 (wing wall), or the sliding door flaps 9 and 9A in the fully open state. The exposed size of 9A, etc., can be set to an appropriate size. In other words, the lengths L1 and L2 of the upper rails 10 and 10C can be set to be approximately the same as the “dimensions of multiplying the door widths W1 and W2 of the sliding door panels 9 and 9A by 2 times” minus “the above-mentioned overlapping dimensions multiplied by 2 times”. size".

In addition, in the present embodiment, the second half portion 10B on the other side in the longitudinal direction of the longest upper rail 10 can be cut. With this configuration, when the door width W2 of the sliding door door piece 9A is smaller than the maximum door width W1, the second half portion 10B side is cut out so as to be approximately twice the length of the door width W2. The upper rail 10C can be set as the length L2 that can guide the sliding door flap 9A. Thereby, for example, in a state where the drive mechanism 20 is attached to the first half 10A, the second half 10B side can be cut, and it can be easily handled even after shipment from the factory. In the upper rail 10, at least the second half portion 10B can have the same cross-sectional shape throughout the entire length, and can be made of metal that can be cut with an appropriate cutting tool.

Furthermore, on the upper rail 10, as shown in FIG. 2, the guide grooves 11 for accommodating the guided members 29 (the first guided member 29A and the second guided member 29B) are set to face downward. Open your mouth. The guide groove 11 is provided to extend over the entire length of the upper rail 10 . In this guide groove 11, the guide body 29c of the guided member 29 is inserted to be guided. The upper rail 10 includes: a groove bottom-shaped portion 12, which defines the groove bottom of the guide groove 11; side plate-shaped portions 13 and 13 on both sides, which define both sides of the groove width direction of the guide groove 11; The guide piece portions 13a, 13a extend from the lower end portions of the side plate-like portions 13, 13 in the directions facing each other. In addition, the upper rail 10 is provided with the protruding pieces 14 and 14 on both sides, and is provided so as to protrude upward from both edge parts in the groove width direction on the top surface side of the groove bottom-shaped part 12 .

Protrusions protruding toward the upper side extend over the entire length of the upper rail 10 at the front end portions in the extending direction of the guide piece portions 13a and 13a on both sides. The protrusions of these guide pieces 13a, 13a engage with annular grooves formed on the outer peripheral surfaces of the rotating bodies 29d, 29d of the guided member 29, so that the rotating bodies 29d, 29d follow these The protrusions of the guide pieces 13a and 13a slide. In addition, the upper rail 10 is not limited to one having the guide pieces 13a and 13a for sliding the respective rotating bodies 29d and 29d provided at intervals on both sides in the door thickness direction. The upper rail 10 may include, for example, one guide piece for hooking and holding the rotating body 29d provided only on one side in the door thickness direction of the guided member 29, or may have other various configurations.

As shown in FIGS. 2 to 5 , the driving mechanism 20 is fixed to the groove bottom-shaped portion 12 of the upper rail 10 . With this configuration, the upper rail 10 can be fixed to a fixed object such as the upper frame 3 of the door frame 2 in which the sliding door flap 9 is constructed while the drive mechanism 20 is integrated with the upper rail 10 . Furthermore, compared to, for example, fixing the driving mechanism 20 to the side plate-shaped portion 13 of the upper rail 10, etc., the size reduction along the door thickness direction can be achieved. As shown in FIGS. 3 and 4 , the drive mechanism 20 includes a first driven rotary wheel 21 and a second driven rotary wheel 25 , which are provided at positions separated in the door width direction, and the one driven rotary wheel 21 constitutes The first rotary wheel and the second driven rotary wheel 25 constitute a second rotary wheel. Further, the drive mechanism 20 includes: a belt-shaped transmission body 28 wound around the first driven rotating pulley 21 and the second driven rotating pulley 25, respectively, and connected to the first guided member 29A; and a drive The belt-shaped transmission body 28 transmits the drive to this part 30 . With this configuration, the first guided member 29A connected to the belt-shaped transmission body 28 can be moved in the door width direction to open and close the sliding door flap 9 by simply driving the drive unit 30 .

The first driven rotary wheel 21 is provided so as to be positioned 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 pulley 25 is provided so as to be positioned 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 this configuration, the first guided member 29A can be slid over substantially the entire length of the first half portion 10A of the longest upper rail 10 by being wound around the belt-shaped transmission bodies 28 . Furthermore, even if it is applied to different door widths W1 and W2, it is not necessary to change the installation positions of the first driven rotating wheel 21 and the second driven rotating wheel 25, or the belt shape. In the case of the length of the transmission body 28, apply it.

The driving unit 30 includes a driving rotary pulley 31 provided between the first driven rotary pulleys 21 and the second driven rotary pulleys 25 and positioned above the upper rail 10 for driving the belt drive. The body 28 transmits the drive; and the motor 35, which drives the rotary wheel 31 to rotate. With this configuration, the first guided member 29A connected to the belt-shaped transmission body 28 can be moved in the door width direction by rotating the driving rotary pulley 31 by the motor 35, and the sliding door flap 9 can be opened and closed. . Furthermore, compared to the case where the drive rotating wheel 31 and the motor 35 are provided at one end of the door width direction, the size along the door width direction can be reduced. Furthermore, compared with the case where the driving rotating wheel 31 is arranged on one side of the door thickness direction of the upper rail 10 , the size reduction in the door thickness direction can be further reduced. By doing so, it is possible to install the door frame 2 which is substantially the same as the door frame of the sliding door device installed in a general building such as a house. Furthermore, for example, the already installed door frame 2 can also be installed, not only for new constructions, but also for remodeling or retrofitting. Thereby, it can be suitable for general residences such as open houses or complex houses, public facilities such as hotel facilities, medical facilities, social welfare facilities, commercial facilities such as office buildings, and various shops. And so on, it is used as the door opening and closing device 1 for opening and closing the sliding door flap 9 provided in the room. Furthermore, since the door opening and closing device 1 is very compact, although the sliding door flap 9 can function as an automatic door, even if it is installed as an indoor sliding door, the appearance of abruptness (interference) can be reduced, and it can be used as an indoor sliding door. It can also be used appropriately.

The first driven rotary wheel 21 and the second driven rotary wheel 25, the first driven wheel shaft 22 and the second driven wheel shaft 26 serving as their respective axes, are parallel to each other. Furthermore, the first driven axle 22 and the second driven axle 26 are provided so as to intersect with "the axial direction of the driving axle 32 of the driving rotary wheel 31 whose axial direction is the door height direction". With such a configuration, the size along the door thickness direction can be reduced more than if the motor 35 is disposed adjacent to the door thickness direction with the axial direction of the drive rotary wheel 31 in the door thickness direction. . In addition, the portion of the belt-shaped transmission body 28 connected to the first guided member 29A and the portion that transmits the drive to the driving rotary pulley 31 may be arranged vertically. Thereby, compared with the case where the axial direction of the 1st driven rotary wheel 21 and the 2nd driven rotary wheel 25 is set as the door height direction, the reduction of the dimension along the door thickness direction can be achieved more effectively.

Furthermore, as shown in FIG. 7 , the motor 35 is configured to be arranged on one side of the door width direction of the driving rotary wheel 31, and the axial direction of the output shaft 36 is the door width direction; Wheel 31 rotates. With this configuration, the size in the door height direction can be reduced more than when the motor 35 is provided so that the axial direction of the output shaft 36 is in the door height direction. In addition, the specific structure of the drive part 30 which consists of these drive rotary wheels 31 and the motor 35 will be described later.

A belt-shaped transmission body 28 (see FIG. 4 ) is wound around the first driven rotating pulley 21 and the second driven rotating pulley 25 in a parallel open manner. The belt-shaped transmission body 28 is connected to the first guided member 29A by the lower side displacement portion 28b, and is displaced in the door width direction, and the upper side displacement portion 28a is displaced in the door width direction opposite to the lower side displacement portion 28b. side (see Figure 2). The first driven rotating pulley 21 and the second driven rotating pulley 25 are provided with the first driven pulley shaft 22 and the second driven pulley shaft 26 inclined so as to displace the lower side displacement portion 28b and the upper side in the belt-shaped transmission body 28 The portion 28a is at a different position in the door thickness direction of the upper rail 10 . With this configuration, the lower displacement portion 28b and the upper displacement portion 28a of the belt-shaped transmission body 28 are arranged at positions shifted in the door thickness direction, and one of the lower displacement portion 28b and the upper displacement portion 28a can be used. The space on the side of the door in the thickness direction is used to configure various machines or components.

The first driven rotary pulley 21 and the second driven rotary pulley 25 are provided with the first driven pulley shaft 22 and the second driven pulley shaft 26 inclined so that the lower displacement portion 28b is located in the substantially center of the door thickness direction of the upper rail 10 The upper displacement portion 28a is located at a position deviated to one side in the door thickness direction of the upper rail 10 . According to this structure, the lower side displacement part 28b located in the substantially center part in the door thickness direction of the upper rail 10 can be connected to the 1st to-be-guided member 29A. Thereby, compared with connecting the lower side displacement portion 28b to the first guided member 29A or one of the door thickness directions of the upper end portion 9a of the sliding door leaf 9 by the connecting member, the first guided member 28b can be more easily The guide member 29A moves stably in the door width direction. Furthermore, various apparatuses and components can be arranged by utilizing the side space in the door thickness direction of the upper displacement portion 28a displaced to one side in the door thickness direction of the upper rail 10.

In addition, the drive rotating wheel 31 and the motor 35 mentioned later are comprised so that it may be provided in one side of the door thickness direction of the upper side displacement part 28a. With this configuration, the drive rotary wheel 31 and the motor 35 constituting the drive unit 30 can be arranged using the space on one side of the upper displacement portion 28a in the door thickness direction. Furthermore, the lower displacement portion 28 b is arranged in the guide groove 11 , and the upper displacement portion 28 a is arranged on the upper side of the groove bottom-shaped portion 12 .
