Modes for Carrying Out the Invention

[0016] Based on the drawings, an automatic door and its construction method according to an embodiment of the present invention will be described.

[0017] (Overview Explanation) In FIGS. 1 to 3, an automatic door 100 according to the present embodiment is shown. The automatic door 100 includes an outer frame 1, a shoji 2 that slides within the outer frame 1, and a sleeve portion 3 fixed within the outer frame 1.

[0018] In the automatic door 100, with the opening and closing of the shoji 2, it changes between a state where the shoji 2 is closed (see FIGS. 1 and 2) and a state where the shoji 2 slides open to the side of the sleeve portion 3 (see FIG. 3). Hereinafter, unless otherwise specified, the automatic door 100 will be described based on the state where the shoji 2 is closed.

[0019] The shoji 2 has a first door panel 21 and a shoji side frame 4.

[0020] The sleeve portion 3 has a second door panel 31 and a sleeve portion side frame 6, and is arranged adjacent to the shoji 2 in the finding direction when viewed in the prospective direction.

[0021] Thus, in the automatic door 100, since the sleeve portion 3 has the sleeve-side frame 6, the sleeve portion 3 having the second door plate 31 can be treated as an integral member. As a result, the workability of assembling the automatic door 100 that requires the assembly of the sleeve portion 3 and the installation work at the installation site is improved.

[0022] (Description of each part) The automatic door 100 shown in FIGS. 1 to 3 is a door device that automatically opens based on commands or information serving as a trigger for the opening operation, such as the detection result of a sensor that detects the start timing of the opening operation, such as a human presence sensor. The automatic door 100 can be installed at any entrance or exit in buildings such as apartment houses, commercial facilities, and offices. The automatic door 100 may be assembled to a certain extent at the factory in advance with some parts and then installed at the site, or all assembly may be performed at the site. FIG. 1 is a front view of the automatic door 100 as seen from inside the building (for example, inside the entrance hall of an apartment house, indoor side) in the prospective direction. FIG. 1 shows the case where the automatic door 100 is in the closed state. FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1, which is a so-called horizontal cross-sectional view. FIG. 3 is a front view of the automatic door 100 when it is approximately half open.

[0023] The automatic door 100 includes an outer frame 1 fixed to the building, a shoji 2 driven by a drive unit and sliding within the outer frame 1, and a sleeve portion 3 fixed within the outer frame 1. In the present embodiment, the upper side in the vertical direction is referred to as the upper side, and the lower side is referred to as the lower side. Also, the same direction as the direction corresponding to the width in the outer frame 1 (in FIGS. 1 to 3, the left-right direction in the drawing) is referred to as the finding direction. Further, the same direction as the depth direction in the outer frame 1 is referred to as the prospective direction. Hereinafter, for convenience of explanation, there may be cases where the direction on the side of the shoji 2 as seen from the sleeve portion 3 in the finding direction is referred to as the right side, and the opposite direction is referred to as the left side. Also, there may be cases where the side of the shoji 2 as seen from the sleeve portion 3 in the prospective direction is referred to as the front side, and the opposite side is referred to as the back side. That is, the sleeve portion 3 is located on the left side and the back side of the shoji 2.

[0024] As shown in FIG. 1, the outer frame 1 is a rectangular frame for supporting the shoji 2 and the sleeve portion 3, and is a member for guiding the sliding opening and closing of the shoji 2. The outer frame 1 is located on the upper side of the rectangle, and includes an upper frame 13 that extends in the horizontal direction, along the finding direction in this embodiment, a lower frame 14 that is located on the lower side of the rectangle and extends parallel to the upper frame 13, and when the shoji 2 is in the closed state, the right side surface of the shoji 2 abuts, and a first vertical frame 11 that is spanned between the upper frame 13 and the lower frame 14, and a second vertical frame 12 that extends parallel to the first vertical frame 11 and is spanned between the upper frame 13 and the lower frame 14. The lower part of the lower frame 14 may be embedded in the floor.

[0025] On the left side surface of the first vertical frame 11, a first vertical recess 11a that extends along the vertical direction is formed. The first vertical recess 11a extends in the range from the upper frame 13 to the lower frame 14.

[0026] On the right side surface of the second vertical frame 12, a second vertical recess 12a that extends along the vertical direction is formed. The second vertical recess 12a extends in the range from the upper frame 13 to the lower frame 14. In this embodiment, the second vertical frame 12 has the same shape as the first vertical frame 11. That is, the first vertical frame 11 and the second vertical frame 12 are interchangeable with each other and are made common as parts. Thereby, the cost can be reduced.

[0027] In addition, guide structures and groove-like structures for guiding the opening and closing movement of the shoji 2 and for fixedly supporting the sleeve portion 3 are formed on the upper frame 13 and the lower frame 14, but the details thereof will be described later.

[0028] The shoji 2 is a door portion that automatically opens and closes in the automatic door 100. The shoji 2 may be, for example, of the kendon type and be fitted into the outer frame 1. The shoji 2 is driven to open and close by, for example, an engine unit housed inside the frame of the upper frame 13. FIGS. 1 and 2 show the state where the shoji 2 is closed in the automatic door 100. FIG. 3 shows the state (semi-open state) in the automatic door 100 where the shoji 2 is opening from the closed state (see FIGS. 1 and 2).

[0029] As shown in FIG. 1, the shoji 2 has a rectangular shoji side frame 4 and a rectangular first door panel 21 fitted and fixed within the rectangular ring of the shoji side frame 4. The first door panel 21 is, for example, a metal plate, a glass plate, or the like. Hereinafter, the case where the first door panel 21 is a glass plate will be exemplified and described.

[0030] The shoji side frame 4 is a frame attached to the outer peripheral portion of the first door panel 21. The shoji side frame 4 is supported by the outer frame 1, and the first door panel 21 is supported by the outer frame 1 via the shoji side frame 4.

[0031] In the automatic door 100, since the shoji 2 has the shoji side frame 4 and the first door panel 21 is fitted into the shoji side frame 4 so that the shoji 2 can be handled as an integral member, even if the first door panel 21 is easily breakable like a glass plate, it has good handling properties. As a result, the workability of assembling the automatic door 100 that requires the installation of the shoji 2 and the installation work at the installation site is improved. For example, operations such as assembling the shoji 2 in advance at the factory, transporting it to the installation site, and assembling it can be easily performed.

[0032] As shown in FIG. 2, when the shoji 2 is in the closed state, the shoji side frame 4 has a door tip frame 41 that abuts against the inner surface, that is, the left side surface, in the finding direction of the first vertical frame 11 of the outer frame 1, a first matching frame 42 that overlaps with the sleeve portion 3 in the prospective direction view, a first upper frame 43 that is guided by the upper frame 13 when the shoji 2 opens and closes, and a first lower frame 44 that is guided by the lower frame 14 when the shoji 2 opens and closes, as shown in FIG. 4. The door tip frame 41, the first matching frame 42, the first upper frame 43, and the first lower frame 44 are linear frames. The first door panel 21 may be fitted into a groove formed on the inner surface of the rectangular ring of the shoji side frame 4 and fixed to the shoji side frame 4. Note that FIG. 4 shows a cross-sectional view taken along the IV-IV arrow in FIG. 3, which is a so-called vertical cross-sectional view.

[0033] The door end frame 41 is a frame extending along the vertical direction. When the shoji 2 is in the closed state, the door end frame 41 is configured to be concealed by the first vertical frame 11 of the outer frame 1 in the perspective view. In the present embodiment, when the shoji 2 is in the closed state, the door end frame 41 fits into and is accommodated in the first vertical recess 11a, so that in the perspective view, whether viewed from the front side (indoor side) or the back side (outdoor side, outside of the building), it overlaps with the first vertical frame 11 and is concealed by the first vertical frame 11. Thereby, the door end frame 41 is in a state of being supported by the first vertical recess 11a of the first vertical frame 11, and the strength of the shoji 2 against the load in the perspective direction is improved. Further, since the door end frame 41 is concealed by the first vertical frame 11, the automatic door 100 has a neat appearance and the design property is improved. Since the shoji 2 opens and closes automatically, there is no particular need to provide a handle for a person to open and close on the door end frame 41, and the fact that the door end frame 41 is concealed by the first vertical frame 11 and the door end frame 41 fits into and is accommodated in the first vertical recess 11a does not cause any hindrance in the use of the automatic door 100.

[0034] The door end frame 41 may be completely fitted into the first vertical recess 11a and completely concealed by the first vertical frame 11 of the outer frame 1, or a part thereof may be fitted into the first vertical recess 11a and the fitted part may be concealed by the first vertical frame 11. When the door end frame 41 is completely fitted into the first vertical recess 11a and completely concealed by the first vertical frame 11 of the outer frame 1, the depth in the finding direction of the first vertical recess 11a should be at least the same as, preferably greater than, the width in the finding direction of the door end frame 41. If the depth in the finding direction of the first vertical recess 11a is greater than the width in the finding direction of the door end frame 41, even when a cushioning material such as rubber is attached to the door contact surface of the door end frame 41, the door end frame 41 can be completely concealed. Also, even when no cushioning material such as rubber is attached to the door contact surface of the door end frame 41, if the depth in the finding direction of the first vertical recess 11a is greater than the width in the finding direction of the door end frame 41, the door end frame 41 can be completely concealed and the door contact surface of the door end frame 41 can be separated from the bottom surface of the first vertical recess 11a when the shoji 2 is closed. Thereby, for example, the generation of a collision sound when closing the shoji 2 can be prevented.

[0035] The first calling frame 42 is a frame member extending along the vertical direction. When the shoji 2 is opened, the first calling frame 42 approaches the second vertical frame 12 of the outer frame 1. In the present embodiment, when the shoji 2 is fully opened, a predetermined gap is secured between the first calling frame 42 and the second vertical frame 12. Thereby, an accident such as pinching a finger does not occur.

[0036] As shown in FIG. 4, the first upper frame 43 is a frame member extending along the finding direction. The first upper frame 43 is guided by a groove-shaped guide structure formed in the upper frame 13 of the outer frame 1 to realize the sliding opening and closing of the shoji 2. In the present embodiment, as shown in FIG. 4, a guide frame 13G is formed in the upper frame 13, where the lower surface portion on the front side is folded upward, and the first upper frame 43 is fitted into a groove-shaped, guide rail-shaped recess formed by this guide frame 13G. The first upper frame 43 realizes the sliding opening and closing of the shoji 2 by being guided by the guide rail-shaped recess formed by the guide frame 13G. In the present embodiment, the first upper frame 43 is in a state of being fitted and accommodated in the guide rail-shaped recess formed by the guide frame 13G, and in the perspective view, it overlaps with the upper frame 13 and is concealed by the upper frame 13. Thereby, the first upper frame 43 is supported by the upper frame 13, and the strength of the shoji 2 against the load in the perspective direction is improved. Further, since the first upper frame 43 is concealed by the upper frame 13, the automatic door 100 has a neat appearance and the design property is improved.

[0037] Note that the first upper frame 43 may be completely concealed by the upper frame 13 of the outer frame 1, or a part of it may be concealed by the upper frame 13.

[0038] The first lower frame 44 is a frame member extending along the finding direction. The first lower frame 44 is guided by a rail portion 14L having a groove-shaped guide structure formed in the lower frame 14 of the outer frame 1 to realize the sliding opening and closing of the shoji 2. For example, a groove 14a extending along the finding direction may be formed in the upper surface portion of the rail portion 14L. When the door wheel of the shoji 2 is arranged on the lower surface portion of the first lower frame 44, the shoji 2 is guided by the lower frame 14 during opening and closing as this door wheel travels along the groove 14a. Note that the first lower frame 44 is exposed and visible in the perspective view.

[0039] As shown in Fig. 1, the sleeve portion 3 has a rectangular sleeve-side frame 6 and a rectangular second door plate 31 that is fitted and fixed within the rectangular ring of the sleeve-side frame 6. The sleeve portion 3 is fixed to the outer frame 1. The sleeve portion 3 is what is called a so-called FIX or FIX portion. The sleeve portion 3 may be fixed to the outer frame 1 after being fitted into the outer frame 1 in, for example, a kendon style. As will be described later, the left side end portion in the finding direction is fitted and fixed into the second longitudinal concave portion 12a of the second longitudinal frame 12 of the outer frame 1.

[0040] The second door plate 31 is, for example, a metal plate material, a glass plate, etc. Hereinafter, the case where the second door plate 31 is a glass plate, that is, a sleeve glass, will be exemplified and described. In the view in the prospective direction, the first door plate 21 of the shoji 2 and the second door plate 31 are bilaterally symmetric. That is, the shape of the second door plate 31 visible in the view in the prospective direction is the same as the shape of the first door plate 21 visible in the view in the prospective direction. The second door plate 31 may use the same dimensions and the same specifications as the first door plate 21. Thereby, the parts of the automatic door 100 can be made common and the cost can be reduced.

[0041] The sleeve-side frame 6 is a frame attached to the outer peripheral portion of the second door plate 31. The sleeve-side frame 6 is fixed to the outer frame 1, and the second door plate 31 is supported by the outer frame 1 via the shoji-side frame 4.

[0042] In the automatic door 100, as described above, since the sleeve portion 3 has the sleeve-side frame 6 and the second door plate 31 is fitted into the sleeve-side frame 6 and the sleeve portion 3 can be handled as an integral member, for example, even if the second door plate 31 is a breakable material such as a glass plate, it has good handling properties. Thereby, the workability of assembling the automatic door 100 that requires the assembly of the sleeve portion 3 and the installation at the installation site is improved. For example, operations such as assembling the sleeve portion 3 in advance at the factory, transporting it to the installation site, and assembling it can be easily performed. That is, the sleeve portion 3 also has good handling properties like the shoji 2.

[0043] As shown in Fig. 2, the sleeve-side frame 6 includes a sleeve vertical frame 61 fixed to the second vertical frame 12, a second mating frame 62 that overlaps with the first mating frame 42 in the prospective direction view, a second upper frame 63 fixed to the upper frame 13, and a second lower frame 64 fixed to the lower frame 14 as shown in Fig. 4. The sleeve vertical frame 61, the second mating frame 62, the second upper frame 63, and the second lower frame 64 are linear frames. The second door panel 31 may be fitted into a groove formed on the inner surface of the rectangular ring of the sleeve-side frame 6 and fixed to the sleeve-side frame 6. In this way, similar to the shoji 2 having the shoji-side frame 4 and the first door panel 21, the sleeve portion 3 having the sleeve-side frame 6 and the second door panel 31 unifies the appearance of the shoji 2 and the sleeve portion 3, creating a sense of unity in the appearance of the automatic door 100 and making it highly designed.

[0044] In the prospective direction view, the sleeve-side frame 6 is preferably shaped (appearance) the same as the shoji-side frame 4 of the shoji 2. Thereby, the shoji 2 and the sleeve portion 3 are symmetrical in the prospective direction view. As a result, the automatic door 100 has a neat appearance and the design property is improved. Note that the sleeve-side frame 6 may have the same dimensions and the same specifications as the shoji-side frame 4. Thereby, the parts of the automatic door 100 can be made common to reduce costs.

[0045] In the prospective direction view, the sleeve vertical frame 61 is concealed by the second vertical frame 12 of the outer frame 1. In this embodiment, the sleeve vertical frame 61 is fixed in a state of being fitted and housed in the second vertical recess 12a. That is, the sleeve vertical frame 61, which is the side end portion of the sleeve portion 3 in the finding direction, is fitted and fixed to the second vertical frame 12 of the outer frame 1. Thereby, in the prospective direction view, the sleeve vertical frame 61 as the side end portion of the sleeve portion 3 in the finding direction overlaps with the second vertical frame 12 and is concealed by the second vertical frame 12. Since the sleeve vertical frame 61 as the side end portion of the sleeve portion 3 in the finding direction is concealed by the second vertical frame 12, the automatic door 100 has a neat appearance and the design property is improved.

[0046] Note that the vertical frame 61 of the sleeve portion may be completely fitted into the second vertical concave portion 12a and completely concealed by the second vertical frame 12 of the outer frame 1, or a part thereof may be fitted into the second vertical concave portion 12a and the fitted part may be concealed by the second vertical frame 12. When the vertical frame 61 of the sleeve portion is completely fitted into the second vertical concave portion 12a and completely concealed by the second vertical frame 12 of the outer frame 1, the depth of the second vertical concave portion 12a in the finding direction and the width of the vertical frame 61 of the sleeve portion in the finding direction may be made the same or more.

[0047] The second calling frame 62 overlaps with the first calling frame 42 in the prospective direction view when the shoji 2 is in the closed state. Thereby, the first calling frame 42 and the second calling frame 62 conceal each other in the prospective direction. As a result, the automatic door 100 has a neat appearance and the design property is improved.

[0048] As shown in FIG. 4, the second upper frame 63 is fixed in a state of being fitted into a concave portion formed in the upper frame 13 of the outer frame 1. The upper frame 13 is formed in an angular U-shape, and the concave portion, which is the inner portion of the U-shape, faces downward. The second upper frame 63 is concealed by the upper frame 13 in the prospective direction view by being fitted into the concave portion of the upper frame 13. That is, the second upper frame 63 as the upper end portion in the sleeve portion 3 is concealed by the upper frame 13. As a result, the automatic door 100 has a neat appearance and the design property is improved.

[0049] Note that the second upper frame 63 may be completely concealed by the upper frame 13 of the outer frame 1, or a part thereof may be concealed by the upper frame 13.

[0050] The second lower frame 64 is placed on a flat portion 14b formed on the upper surface of the lower frame 14 of the outer frame 1. The second lower frame 64 may be fixed to the flat portion 14b. That is, the lower end portion of the sleeve portion 3 may be fixed to the lower frame 14. The second lower frame 64 is exposed and visible in the prospective direction view.

[0051] The installation of the automatic door 100 in the present embodiment can be performed as follows, for example.

[0052] The shoji 2 and the sleeve part 3 may be pre-assembled at the factory in advance. The outer frame 1 may also be pre-assembled at the factory in advance, but considering the convenience of transportation, it may also be assembled on-site.

[0053] As shown in FIG. 1, when installing the automatic door 100 in a building, first, an outer frame fixing step of fixing the outer frame 1 to the building structure is performed.

[0054] Next, a shoji fitting step of fitting the shoji 2 into the outer frame 1 is performed. Also, a sleeve part fitting step of fitting and fixing the sleeve part 3 into the outer frame 1 is performed. In this embodiment, the fitting of the shoji 2 and the sleeve part 3 into the outer frame 1 can be performed by the dovetail method.

[0055] In the shoji fitting step, the door end frame 41 of the shoji 2 is accommodated in the first vertical frame 11 of the outer frame 1, and in the perspective view, the door end frame 41 and the first vertical frame 11 are overlapped.

[0056] In the sleeve part fitting step, the sleeve part vertical frame 61 of the sleeve part 3 is accommodated in the second vertical frame 12 of the outer frame 1, and in the perspective view, the sleeve part vertical frame 61 and the second vertical frame 12 are overlapped. Further, the sleeve part vertical frame 61 is fixed to the second vertical frame 12.

[0057] In this way, the automatic door 100 can be provided, and the construction of installing the automatic door 100 in a building or the like can be performed.

[0058] As described above, it is possible to provide an automatic door with high workability in assembly and installation at the installation site and a construction method thereof.

[0059] 〔Alternative Embodiment〕 (1) In the above embodiment, the case where the shoji 2 and the sleeve part 3 are symmetrical about the left and right in the perspective view has been described, but being symmetrical about the left and right is not an essential requirement.

[0060] (2) In the above embodiment, the case where the automatic door 100 includes an outer frame 1 fixed to a building, a shoji 2 driven by a driving unit and sliding within the outer frame 1, and a sleeve portion 3 fixed within the outer frame 1 has been described. Further, the shoji 2 has a first door panel 21 and a shoji side frame 4, the sleeve portion 3 has a second door panel 31 and a sleeve side frame 6, and the case where the shoji 2 and the sleeve portion 3 are symmetric about the left and right in the perspective view has been described. Also, when the shoji 2 is in the closed state, the door end frame 41 of the shoji 2 is concealed by the first vertical frame 11 of the outer frame 1 in the perspective view, and the first upper frame 43 of the shoji 2 is concealed by the upper frame 13 in the perspective view has been described.

[0061] However, as long as the sleeve portion 3 has a sleeve side frame 6 and a second door panel 31 similar to the shoji 2, the appearance of the shoji 2 and the sleeve portion 3 is unified, and a sense of unity is created in the appearance of the automatic door 100, making it highly designable. Therefore, it is not essential that the shoji 2 and the sleeve portion 3 be symmetric about the left and right in the perspective view, or that the door end frame 41 of the shoji side frame 4 in the shoji 2 be concealed by the first vertical frame 11. Also, the shoji 2 and the sleeve portion 3 are not limited to being single sheets each.

[0062] FIG. 5 shows a front view of an example of an automatic door 200 having two shojis 2 and two sleeve portions 3 each, as viewed from the outside of the building in the perspective direction. In FIG. 5, within the outer frame 1, shojis 2A, 2B as the shoji 2 and sleeve portions 3A, 3B as the sleeve portion 3 are fitted. In the automatic door 200, in the order from the left side to the right side in the illustration of FIG. 5, the sleeve portion 3A, the shoji 2A, the sleeve portion 3B, and the shoji 2B are arranged. That is, the sleeve portion 3A is arranged adjacent to the shoji 2A in the finding direction in the perspective view. Also, the sleeve portion 3B is arranged adjacent to the shoji 2B in the finding direction in the perspective view.
