Description

Technical Field

[0001] The present invention relates to a sliding door device, and more particularly to a sliding door device including a first sliding door and a second sliding door.

Background Art

[0002] A door device including a first sliding door and a second sliding door that form a booth is disclosed in Patent Document 1. In the door device, the first sliding door opens and closes in a first direction, and the second sliding door opens and closes in a second direction. In the fully closed position of the first sliding door and the second sliding door, the end portion on the door leading side of the first sliding door and the end portion on the door leading side of the second sliding door form a butting portion. In the fully open position of the first sliding door and the second sliding door, an opening enlarged to the corner portion of the booth can be formed, and a space for a wheelchair to enter and exit can be secured.

[0003] Such a door device is installed, for example, in a booth of a narrow toilet in a living room of a medical and welfare facility. However, the first sliding door and the second sliding door are of the overhead type and each has an upper frame extending at a predetermined angle. Therefore, when suspending the door body of one sliding door, it is necessary to secure a space so as not to interfere with the upper frame of the other sliding door.

[0004] Here, when it is desired to reduce the size of the booth, it is conceivable to reduce the width dimension of the door body. However, if the width dimension of the door body is significantly reduced, the weight of the door body (which is originally lightweight) will be further reduced, and there is a risk that the suspended door body will rattle during opening and closing, interfering with the smooth opening and closing operation of the door body.

[0025] [C] Second sliding door The second sliding door 2 will be explained with reference to Figures 1 and 5-8. [C-1] Door Body The door body 20 is equipped with a hanger roller 200 at its upper end and a guide groove 201, which is a concave groove, at its lower end. A sway-preventing roller 202 is provided on the lower surface (floor surface FL) of the second door pocket 4 near the door-side end 400 of the inner portion 40. The door body 20 slides in the second direction as the hanger roller 200 at the upper end rolls on the rail 9 and the guide groove 201 at the lower end is guided by the second sway-preventing roller 202. The second sliding door 2 is equipped with a locking device (French bolt) 203 that maintains the closed position of the second sliding door 2. The locking device 203 is provided on the door-side and upper portion of the inner surface of the door body 20, and a locking rod 2030 protrudes upward and locks into a locking portion 602 (Figure 8) provided on the door-side portion of the inner surface 60 of the upper frame 6 of the second sliding door 2. A handle h is provided on the leading edge portion of the door body 20. In Figures 5 and 6, reference numeral 204 indicates the trailing end face of the door body 20.

[0026] [C-2] Upper frame The second upper frame 6 is a rectangular box-shaped body with a vertically rectangular cross-section, and the upper end of the door body 20 protrudes into the second upper frame 6 from an opening at its lower end. A rail 9 is fixed at a predetermined height position on the inner surface of the outer surface portion 60 that forms the outer visible surface of the second upper frame 6. The rail 9 is arranged in an inclined shape with the door-edge side being lower, and is designed to close automatically after opening. An end stopper 604 is provided on the outer surface portion 60 to maintain the open position of the door body 20 (Figure 8).

[0027] A second inspection cover 61, which has an L-shape in cross-section, is formed from a facing surface 610 that forms the inner visible surface of the second upper frame 6 and a bottom surface 611 that forms the inner portion of the bottom surface, and the second inspection cover 61 is removable from the second upper frame 6. Mounting pieces 613 are provided in a cantilevered manner within the second upper frame 6 so as to be located on the inner surfaces of both ends in the width direction of the facing surface 610 of the second inspection cover 61, and both ends in the width direction of the facing surface 610 of the second inspection cover 61 are detachably attached to the mounting pieces 613 with screws 612.

[0028] As shown in Figure 7, a protruding projection 600 is provided at the lower end of the outer surface portion 60 of the second upper frame 6, and a rising edge 601 is formed on the inside of the lower end of the outer surface portion 60. The upper end portion of the door body 20 protrudes into the second upper frame 6 from between the rising edge 601 and the rising edge 6110 of the lower surface 611 of the second inspection cover 61.

[0029] [C-3] Tobukuro Department The second door pocket section 4 consists of an inner section 40, an outer section 41, and a door-end side vertical frame 42. The door-end side end 400 of the inner section 40 is located closer to the door-end than the door-end side end 410 of the outer section 41, and the visible width of the inner section 40 is shorter than the visible width of the outer section 41.

[0030] [D] Hanging of the door body Referring to Figures 10 and 11, the installation of the door body 20 of the second sliding door 2 will be explained. When installing the door body 20, the second inspection cover 61 forming the inner portion of the second upper frame 6 is removed, and the first inspection cover 51 forming the inner portion of the first upper frame 5 is also removed. As shown in Figure 10, in plan view, the door body 20 is installed in an inclined position, but the leading edge end 400 of the inner portion 40 of the second door pocket 4 is located on the tail end side by a dimension X than the leading edge end 410 of the outer portion 41, and a space is formed on the leading edge side of the inner portion 40 where the tail end portion of the door body 20 extends in an inclined shape in plan view. At this time, since the anti-sway roller 202 on the floor surface FL is located near the leading edge end 400 of the inner portion 40 of the second door pocket section 4, the trailing edge portion of the door body 20 does not protrude into the outer portion 41 of the second door pocket section 4 when the door body 20 is inclined, and the door body 20 can be smoothly inclined. If the anti-sway roller 202 were located closer to the leading edge end 410 of the outer portion 41 of the second door pocket section 4 than to the leading edge end 400 of the inner portion 40 of the second door pocket section 4, the inclination angle between the door body 20 and the rising edge 601 of the lower end of the outer surface portion 60 of the second upper frame 6 would increase in plan view, causing the trailing edge portion of the door body 20 to come into contact with the outer portion 41 of the second door pocket section 4, making the hanging operation difficult. On the other hand, if the anti-sway roller 202 is positioned closer to the tail end than the leading end 400 of the inner portion 40 of the second door pocket section 4, the tail end of the door body 20 will be positioned closer to the tail end than the leading end 400 of the inner portion 40 of the second door pocket section 4. As a result, the tail end of the door body 20 and the leading end 400 of the inner portion 40 of the second door pocket section 4 will come into contact, making the hanging operation difficult.

[0031] The upper diagram in Figure 11 corresponds to Figure 10, and the lower diagram in Figure 11 shows the inclined position of the door body 20 based on the conventional door pocket section 4'. The inner portion 40' and outer portion 41' of the door pocket section 4' have the same visible width, and when a door body 20 with the same width dimension is in an inclined position, the position of the door-side end of the door body 20 will protrude towards the door-side by a dimension X compared to the position of the door-side end of the door body 20 shown in Figure 10, requiring a larger hanging space. In other words, in the conventional example shown in the lower diagram of Figure 11, if it is desired to reduce the dimensions of the booth on the second sliding door 2 side (distance between the first wall α and the first sliding door 1), this can be achieved without reducing the width dimension of the door body 20 by adopting the configuration shown in Figures 10 and 11.
