DETAILED DESCRIPTION OF THE INVENTION

[0008] As shown in Figures 1 to 8, the sliding door device 1 according to each embodiment of the present invention is configured to include an opening 2 provided in a wall W, a sliding door 3 positioned behind the opening 2 for opening and closing the opening 2, a transom 4 provided above the sliding door 3, and vibration suppression means 5. In the following description, up, down, left, right, front, and rear are defined as directions shown in the drawings. In addition, cross-sectional hatching is omitted in the cross-sectional views. Furthermore, while Figure 1 illustrates an example of a sliding door device 1 equipped with double-swing sliding doors 3,3, the sliding door device 1 according to each embodiment of the present invention can be applied to both a sliding door device 1 equipped with double-swing sliding doors 3,3 and a sliding door device 1 equipped with a single-swing sliding door 3.

[0009] When the sliding door device 1 is viewed from the front, as shown in Figure 1(a), the opening 2, the three-sided frame 20 surrounding the opening 2, and the sliding door 3 provided on the rear side of the three-sided frame 20 so as to be able to open and close the opening 2 can be seen. When the sliding door device 1 is viewed from the rear side, the sliding door 3 and the transom 4 can be seen as shown in FIG. 1(b). In this specification, for convenience, the side from which the three-sided frame 20 is visible is defined as the front side, and the side from which the blind is visible is described as the rear side; however, if the side from which the blind is visible is defined as the front side, then the side from which the three-sided frame is visible becomes the rear side.

[0010] As shown in FIG. 1(a), the opening 2 is provided with a three-sided frame 20 along the left, right, and upper edges of the opening 2, and walls W are constructed to extend above, to the left, and to the right of this three-sided frame 20. That is, the three-sided frame 20 is composed of left and right vertical frames 20S, 20S and a top frame 21T. The frame 20 is connected and fixed to the horizontal base material 12 and vertical base material 11 (described later) located outside the frame 20 via connectors 19 (see Figures 2 and 7(b)). The wall W is composed of a frame 10 provided so as to extend above, to the left, and to the right of the three-sided frame 20, a wall surface forming body provided on the surface of the frame 10, and a wall finishing member provided on the surface of the wall surface forming body.

[0011] 2 to 8, the skeleton 10 is composed of, for example, vertical base members 11, horizontal base members 12, runners 13, and studs 14. For example, lip channel steel is used as the vertical base members 11 and the horizontal base members 12, and C-type studs, which are wall base members, are used as the studs 14. For example, vertical base members 11 are provided at intervals, and horizontal base members 12 are provided between the vertical base members 11, and runners 13 are attached to these horizontal base members 12, and studs 14 are erected between the upper and lower runners 13, 13 at predetermined intervals, thereby constructing the main body 10. Then, a wall forming body, such as gypsum board 15, is attached to the studs 14, 14... of the main body 10 using screws such as screws not shown, and a wall finishing material such as wallpaper or paint is applied to the outer surface (surface) of the gypsum board 15, thereby constructing a wall W as shown in Figures 1(a) and (b).

[0012] As shown in Figure 2, the crossbeam 4 is composed of a hollow, elongated member that is long horizontally and has an inverted concave cross section with an open bottom, and includes a front panel 41, an upper panel 42, a rear panel 43, a left panel 44, and a right panel 45 as side panels of the main body. That is, the crosspiece 4 is fixed by being connected to the body 10 at the front panel 41 side, which serves as a body side panel. For example, as shown in Figure 2, the crossbeam 4 is connected by connecting members 4c such as screws via mounting members 4a such as brackets between the upper plate 42 on the front plate 41 side and the horizontal base material 12 of the main body 10, and by connecting members 4c such as screws between the lower end portions 41L on the left and right center sides of the front plate 41 and the upper frame 20T of the three-sided frame 20. As shown in Figure 2, the transom 4 is formed integrally with the front plate 41, the upper plate 42, and the upper end of the rear plate 43, and the portions forming the center and lower part of the rear plate 43 are configured to be detachable from the upper end of the rear plate 43. Since the portions forming the center and lower part of the rear plate 43 can be easily detached, the transom 4 is configured to be easy to maintain.

[0013] As shown in FIG. 1(b), inside the transom 4, a guide rail 46 is provided which continues horizontally in the left-right direction over the range in which the sliding door 3 can move left and right. The guide rail 46 is provided, for example, on the rear surface (the rear surface of the front panel 41 in Figure 2) of the front panel 41, which serves as a body side panel that is connected to the body 10 in the crossbeam 4, in other words, on the front inner surface of the crossbeam 4. On the upper end side of the sliding door 3, a moving body 31 called a hoist or the like is provided which is engaged with the guide rail 46 and is configured to be movable along the guide rail 46. As shown in Figure 1(b), the moving body 31 includes, for example, a door-tip side moving body 31F provided at the upper end of the door tip 3F side of the sliding door 3, and a door-tail side moving body 31R provided at the upper end of the door tail 3R side of the sliding door 3. A moving body 31 provided on the upper end side of the sliding door 3 moves along a guide rail 46, so that the sliding door 3 can move in a direction to open and close the opening 2.

[0014] In addition, in the sliding door device 1 according to each embodiment of the present invention, as shown in FIG. 1(b), the trailing edge 3R of the left sliding door 3 faces the inner surface of the left panel 44 of the transom 4, and the trailing edge 3R of the right sliding door 3 faces the inner surface of the right panel 45 of the transom 4, and there is no vertical frame facing the trailing edge 3R of the sliding door 3. That is, the sliding door device 1 according to the present invention does not have vertical frames facing the trailing edge 3R of the sliding door 3 below the left and right ends 4E, 4E of the transom 4, as shown in FIG. 1(b).

[0015] Also, in Figure 2, symbol 30 is a guide member installed on the floor F to prevent the lower end of the sliding door 3 from swinging back and forth, and is fixed to the rear sides of the left and right vertical frames 20S, 20S of the three-sided frame 20 by connecting members 30a such as brackets, for example. That is, the lower end side of the sliding door 3 is formed into a guide groove 3L that is guided by a guide member 30, and is configured to suppress forward and backward vibration of the lower end side of the sliding door 3 when the sliding door 3 moves in the opening and closing direction.

[0016] As described above, the sliding door device 1 according to each embodiment of the present invention is configured without a vertical frame facing the trailing edge 3R of the sliding door 3, and therefore, as shown in FIG. 1(b), door stops 47 are provided on both the left and right ends of the guide rail 46 to collide with the trailing edge moving body 31R of the sliding door 3 and stop the movement of the sliding door 3. The door stop 47 has a portion that collides with the trailing edge side moving body 31R, and is made of a shock absorber such as rubber.

[0017] In other words, the sliding door device 1 of the present invention comprises a sliding door 3 that opens and closes an opening 2, and a transom 4 attached to the building frame 10 so as to be positioned above the sliding door 3, and is configured so that the sliding door 3 can move in the direction of opening and closing the opening 2 by moving a moving body 31 attached to the upper end of the sliding door 3 along a guide rail 46 provided on the inside of the transom 4, and the movement of the sliding door 3 is stopped by the trailing edge side moving body 31R provided on the trailing edge 3R side colliding with a door stop 47 provided on the end side of the guide rail 46, and is applied to a sliding door device 1 that does not have a vertical frame facing the trailing edge 3R of the sliding door 3, and is configured so as to include a vibration suppression means 5 that suppresses vibration when the trailing edge side moving body 31R of the sliding door 3 collides with the door stop 47. In FIG. 1(a), the approximate position where the vibration suppressing means 5 is provided in each embodiment of the sliding door device 1 according to the present invention is indicated by a dotted line. 2 to 8, the moving body 31 and the guide rail 46 are not shown, and the position where the door stop 47 is provided is shown by an imaginary line (two-dot chain line).

[0018] Hereinafter, each embodiment of a sliding door device 1 according to the present invention will be described with reference to FIGS. 3 to 8 show views corresponding to the cross sections seen from the arrow B in FIGS. 1(a) and (b), and FIG. 1(b) shows views corresponding to the cross sections seen from the arrow C in FIGS. 1(a) and (b), i.e., a vertical cross section near the right end of the blind 4 and a horizontal cross section near the right end of the blind 4, but the area near the left end of the blind 4, which is not shown, is also configured in the same way.

[0019] Embodiment 1 In the sliding door device 1 of embodiment 1, as shown in Figures 1(b) and 3, the vibration suppression means 5 is composed of a vibration suppression plate 6X connected to the lower end 41L of the front plate 41, which is a body side panel on the end 4E side of the interlock 4, and to the body 10. That is, the vibration suppressing means 5 is configured by connecting the vibration suppressing plate 6X to the lower end 41L of the front plate 41 on the right end 4E side of the transom 4 and the body 10. Although not shown, the vibration suppressing means 5 is similarly configured by connecting a vibration suppressing plate 6X to the lower end 41L of the front plate 41 on the left end 4E side of the transom 4 and the body 10.

In other words, the frame-side vibration suppression plate 6A is a convex-shaped member. The blind-side vibration suppression plate 6B includes a vertical plate 62a that functions as a connecting plate to the vertical plate 61a of the frame-side vibration suppression plate 6A, and an blind connecting plate 62b that extends from the rear edge of the vertical plate 62a in a direction perpendicular to the plate surface of the vertical plate 62a. In other words, the blind-side vibration suppression plate 6B is an L-shaped member.

[0021] For example, as shown in FIG. 3, upper and lower connecting plates 61c, 61c of the frame-side vibration suppression plate 6A are connected to the studs 14 of the frame 10 and the vertical base material 11 by screws 6a. Furthermore, the interlocking connecting plate 62b of the interlocking side vibration suppression plate 6B is connected to the lower end 41L of the front plate 41 on the end 4E side of the interlocking side 4 by a screw 6a, and the vertical plate 62a of the interlocking side vibration suppression plate 6B and the vertical plate 61a of the body side vibration suppression plate 6A are connected by a screw 6a as a connecting means. As the screw 6a, for example, a drill screw or the like may be used. As described above, the vibration suppressing plate 6X is connected to the lower end 41L of the front plate 41 on the end 4E side of the transom 4 and the body 10, thereby forming the vibration suppressing means 5.

[0022] According to the sliding door device 1 of embodiment 1, the vibrations that occur when the sliding door 3 moves in the opening direction and the trailing edge moving body 31R collides with the door stop 47 are damped through the door stop 47, guide rail 46, interlock 4, vibration suppression plate 6X, and main body 10, so that the vibrations that occur when the sliding door 3 moves in the opening direction and the trailing edge moving body 31R collides with the door stop 47 can be suppressed.

Although not shown, the vibration suppressing means 5 is similarly configured by connecting a vibration suppressing plate 6Y to the lower end 41L of the front plate 41 on the left end 4E side of the transom 4 and the body 10.

[0024] As shown in Figure 4, the vibration suppression plate 6Y is composed of a body-side vibration suppression plate 6C connected to the body 10, an interceptor-side vibration suppression plate 6D connected to the lower end 41L of the front plate 41 on the end 4E side of the interceptor 4, and a screw 6a as a connecting means for connecting the body-side vibration suppression plate 6C and the interceptor-side vibration suppression plate 6D. The body-side vibration suppression plate 6C is composed of a horizontal plate 63a that functions as a connecting plate to the blind-side vibration suppression plate 6D, and a vertical plate 63b that extends from one edge of the horizontal plate 63a in a direction perpendicular to the plate surface of the horizontal plate 63a. The interlocking side vibration suppression plate 6D comprises a horizontal plate 64a which functions as a connecting plate to the horizontal plate 63a of the body side vibration suppression plate 6C, and an interlocking connecting plate 64b which extends from the rear edge of the horizontal plate 64a in a direction perpendicular to the plate surface of the horizontal plate 64a. That is, as shown in FIG. 4(c), the frame-side vibration suppression plate 6A and the blind-side vibration suppression plate 6B are L-shaped members.

[0025] For example, as shown in FIG. 4, the vertical plate 63b of the frame-side vibration suppression plate 6C is connected to the stud 14 of the frame 10 and the vertical base material 11 by the screw 6a. Furthermore, the interlocking connecting plate 64b of the interlocking side vibration suppression plate 6D is connected to the lower end 41L of the front plate 41 on the end 4E side of the interlocking plate 4 by a screw 6a, and the horizontal plate 64a of the interlocking side vibration suppression plate 6D and the horizontal plate 63a of the body side vibration suppression plate 6C are connected by a screw 6a as a connecting means.

[0028] As shown in Figure 5, the vibration suppression plate 7 is composed of a body-side connecting plate portion 71 connected to the body 10 and a blind-side connecting plate portion 72 connected to the upper portion 41U of the front plate 41 on the end 4E side of the blind 4. That is, as shown in FIG. 5(c), the vibration suppressing plate 7 is an L-shaped member.

[0029] For example, as shown in Figure 5, the body side connecting plate portion 71 is connected to the vertical base material 11 of the body 10 by a screw 6a, and the interlock side connecting plate portion 72 is connected to the upper part 41U of the front panel 41 on the end 4E side of the interlock 4 by a screw 6a. As described above, the vibration suppressing plate 7 is connected to the upper portion 41U of the front plate 41 on the end portion 4E side of the interlock 4 and the body 10, thereby forming the vibration suppressing means 5.

[0030] According to the sliding door device 1 of embodiment 3, similarly to the sliding door devices 1 of embodiments 1 and 2, the vibrations that occur when the sliding door 3 moves in the opening direction and the trailing edge moving body 31R collides with the door stop 47 are damped through the door stop 47, guide rail 46, transom 4, vibration suppression plate 7, and main body 10, so that the vibrations that occur when the sliding door 3 moves in the opening direction and the trailing edge moving body 31R collides with the door stop 47 can be suppressed.

That is, as shown in FIG. 6(c), the vibration suppression plate 8X is a member that extends in the left-right direction and has an L-shaped cross section.

[0033] For example, as shown in Figure 6, the body side connecting plate portion 81 is connected by a screw 6a to a stud 14, which is the body side body 10 located on the end 4E side of the transom 4, and the transom side connecting plate portion 82 is connected by a screw 6a to the lower end surface 41LF of the lower end portion 41L of the front plate 41 on the end 4E side of the transom 4.

That is, the vibration suppressing plate 8Y has a configuration in which the vibration suppressing plate 8X of the fourth embodiment is elongated in the left-right direction.

[0037] For example, as shown in Figures 7(b) and (c), the vibration suppression plate 8Y has the blind-side connecting plate portion 82L at one end in the left-right direction connected to the lower end surface 41LF of the front plate 41 of the blind 4 by a screw 6a, and the body-side connecting plate portion 81L at one end connected to a stud 14 positioned below the lower end surface 41LF by a screw 6a, and the blind-side connecting plate portion 82L at the other end in the left-right direction connected to the lower end surface 41LF of the front plate 41 at the end 4E of the blind 4 by a screw 6a, and the body-side connecting plate portion 81L at the other end connected to a stud 14 positioned below the lower end surface 41LF by a screw 6a.

[0038] According to the sliding door device 1 of embodiment 5, the vibrations that occur when the sliding door 3 moves in the opening direction and the trailing edge moving body 31R collides with the door stop 47 are damped through the door stop 47, the guide rail 46, the interlock 4, the vibration suppression plate 8Y which is a long member that is long in the left-right direction, and the main body 10, so that the vibrations that occur when the sliding door 3 moves in the opening direction and the trailing edge moving body 31R collides with the door stop 47 can be more effectively suppressed.

[0039] Embodiment 6 In the sliding door device 1 according to the sixth embodiment, as shown in FIG. 8, the vibration suppressing means 5 is composed of a vibration suppressing plate 9 connected to the side plate on the end 4E side of the transom 4 and to the frame 10. That is, the vibration suppressing means 5 is configured by connecting the vibration suppressing plate 9 to the outer surface of the right plate 45 of the interlock 4 and the body 10. Similarly, although not shown, the vibration suppressing means 5 is configured by connecting a vibration suppressing plate 9 to the outer surface of the left plate 44 of the interlock 4 and the body 10 .

[0040] As shown in Figure 8, the vibration suppression plate 9 is composed of a body-side connecting plate portion 91 connected to the body 10 located near (near the front side of) the side plate (right plate 45, left plate 44) on the end 4E side of the transom 4, and a transom-side connecting plate portion 92 connected to the outer surface of the side plate (right plate 45, left plate 44) on the end 4E side of the transom 4. That is, as shown in Figure 8(b), the vibration suppression plate 9 is composed of a long member, for example, with an L-shaped cross section, in which case the above-mentioned body side connecting plate portion 91 is formed by one plate portion of the L shape, and the blind side connecting plate portion 92 is formed by the other plate portion of the L shape.

[0041] For example, as shown in Figure 8, the longitudinal direction of the elongated member with an L-shaped cross section that constitutes the vibration suppression plate 9 is directed vertically (up and down), and the body-side connecting plate portion 91 formed by one plate portion of the L-shape is connected by screws 6a to the vertical base material 11 of the body 10 located near (near the front side of) the side plate (right plate 45, left plate 44) on the end 4E side of the transom 4, and the body-side connecting plate portion 92 formed by the other plate portion of the L-shape is connected by screws 6a to the outer surface of the side plate (right plate 45, left plate 44) on the end 4E side of the transom 4. As described above, the vibration suppressing plate 9 is connected to the side plate on the end 4E side of the interlock 4 and the body 10, thereby forming the vibration suppressing means 5.

[0042] According to the sliding door device 1 of embodiment 6, the vibrations that occur when the sliding door 3 moves in the opening direction and the trailing edge moving body 31R collides with the door stop 47 are damped through the door stop 47, the guide rail 46, the transom 4, the vibration suppression plate 9 which is a long member that is long in the vertical direction, and the main body 10, so that the vibrations that occur when the sliding door 3 moves in the opening direction and the trailing edge moving body 31R collides with the door stop 47 can be more effectively suppressed.

[0043] Furthermore, according to the sliding door device 1 of embodiments 1 to 6, the vibration suppression means 5 is configured such that vibration suppression plates (6X, 6Y, 7, 8X, 8Y, 9) are installed inside the wall W and connected to the interlock 4 and the main body 10. That is, according to the sliding door device 1 of embodiments 1 to 6, the vibration suppression plates (6X, 6Y, 7, 8X, 8Y, 9) are configured so as not to protrude outward from the outer surface (surface) of the wall forming body, such as the gypsum board 15, thereby making it possible to suppress vibration when the sliding door 3 moves in the opening direction and the door tail side moving body 31R collides with the door stop 47, and also improving workability and aesthetics. In the sliding door device 1 according to the sixth embodiment, the rear edge of the interlocking-side connecting plate 92 may be configured to protrude outward from the outer surface (surface) of the wall forming member, such as the gypsum board 15. In this case, for example, a wall finishing member such as wallpaper or paint may be applied to cover the rear edge of the interlocking-side connecting plate 92 that protrudes outward from the outer surface (surface) of the gypsum board 15.

[0044] In the sliding door device 1 according to the present invention, the vibration suppressing means 5 may be configured by a vibration suppressing plate connected to the transom 4 and the frame 10. Even with this configuration, the vibrations that occur when the sliding door 3 moves in the opening direction and the trailing edge moving body 31R collides with the door stop 47 are damped through the door stop 47, guide rail 46, transom 4, vibration suppression plate, and main body 10, so that the vibrations that occur when the sliding door 3 moves in the opening direction and the trailing edge moving body 31R collides with the door stop 47 can be suppressed.
