Summary of the Invention

Problems to be Solved by the Invention

[0004] For example, when a sliding door is provided in a toilet booth, usually the sliding door is installed inside the toilet booth. If it is installed outside, the mechanism part of the sliding door will exist on the outside, making it easy to access the mechanism part of the sliding door from the outside, which is not preferable from the viewpoint of security (taking measures against this will increase the cost). When trying to install a sliding door inside a narrow space such as a toilet booth, the working space is also limited. The technique disclosed in Patent Document 1 involves assembling a square frame in advance and then attaching it. However, installing a frame assembled in advance in this way can be difficult or impossible in an environment where the working space is limited. Also, considering the work done by one person, the work of installing a pre-assembled frame was not necessarily excellent in terms of workability.

[0005] In view of the above points, an object of the present invention is to provide a construction method and a sliding door unit that are excellent in workability for installing frame members for providing a sliding door even in a relatively narrow working space, or a construction method and a sliding door unit that are excellent in workability for installing frame members even in the installation work by one person.

Mode for Carrying Out the Invention

[0026] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. It should be noted that the following embodiments are one form when embodying the present invention and do not limit the present invention within its scope.

[0027] Figs. 1 to 3 are views showing the installation state of the sliding door unit according to the embodiment of the present invention. Specifically, Fig. 1 is a front view, Fig. 2 is a cross-sectional view, and Fig. 3 is a longitudinal sectional view. In the present embodiment, a toilet booth is taken as an example of the installation location of the sliding door unit 1. The toilet booth is formed by being partitioned by a panel body 2 and has an opening serving as an entrance and exit. The sliding door unit 1 is provided as a hanging-type sliding door for opening and closing this opening. The sliding door unit 1 is installed on the indoor side of the toilet booth. In Fig. 2, an example is shown in which two sides of the toilet booth are partitioned by a panel body (the other two sides are constituted by the building structure (not particularly shown) etc.). As shown in Figs. 1 to 3, the sliding door unit 1 includes a sliding door 14, a guide rail (guide member) 13 for sliding the sliding door 14 in a hanging manner, a seamless (upper frame) 12 for installing the guide rail (guide member) 13 at the upper part of the opening G, a vertical frame constituting the door stop of the sliding door 14, and the vertical frame 11 having an upper frame load receiving portion 113 (see Fig. 8) for supporting one end side of the seamless (upper frame) 12 when the seamless (upper frame) 12 is installed with respect to the upper part of the opening G at the upper part.

[0028] The vertical frame 11 and the seamless 12 are frame members for providing a hanging-type sliding door. The present invention mainly relates to frame members and a construction method for installing them.

[0029] The vertical frame 11 is installed via a C-channel 111 with respect to the wall surface (side panel 2S2) on the side of the opening G, and constitutes the door stop on the door tip side of the sliding door 14. As shown in the cross-sectional views of FIGS. 6(b) and 7(b), the vertical frame 11 is a member with a hollow basic form, and both side surfaces at both ends of the side surface 115 on the wall surface side extend toward the wall surface side, so that it has a recess 114 opening to the wall surface side. The recess 114 is a portion for receiving and engaging the C-channel 111, and a protrusion 1141 that abuts against the C-channel 111 is formed on the inner surface side. Thereby, the workability of inserting the C-channel 111 into the recess 114 is excellent, and the vertical frame 11 can be engaged with the C-channel 111 without rattling. Further, a screw groove 116 for receiving a tapping screw for attaching an upper surface member is formed on the inner surface side of the hollow portion of the vertical frame 11. The screw groove 116 is formed along the longitudinal direction (vertical direction) of the vertical frame 11 and also has a function as a protrusion that abuts against the C-channel 112 which is a floor fixing member, whereby the vertical frame 11 is engaged with the C-channel 112 without rattling. Here, it is configured to also have a function of abutting against the C-channel 112 in the screw groove, but of course, a member that abuts against the C-channel 112 may be formed separately from the screw groove. Further, the protrusion 1141 that abuts against the C-channel 111 in the recess 114 may be constituted by a screw groove. An upper frame load receiving portion 113 (see FIG. 8), which is an L-shaped member (angle material), for supporting one end side of the blind 12 during the assembly work of the blind 12, is attached to the upper part of the vertical frame 11. Further, as a configuration as a door stop on the door tip side, the vertical frame 11 includes a recess formed at a location where the door tip of the sliding door 141 comes into contact, and a key engagement hole 118 that engages with a key provided on the sliding door 141.

[0030] As shown in Fig. 3, the blind 12 is installed on the wall surface (upper panel 2T) above the opening G, and is a member for supporting components such as a guide rail 13 for slidably suspending the sliding door 14 and an automatic closing device (a mechanical mechanism for automatically closing the sliding door 14 slowly) 15. A cover 16 for covering the mechanism parts such as the guide rail 13 is also attached to the blind 12. As shown in the longitudinal sectional view in Fig. 12, the blind 12 is a member with a hollow basic shape, and includes a beam portion 121 to which components such as the guide rail 13 are attached on the lower surface side, and a mounting plate 122 that serves as a mounting surface for the wall surface (upper panel 2T). On the blind 12, protrusions for positioning the attached members such as the guide rail 13, screw grooves of tapping screws, screw holes, and partition plates provided in the hollow for reinforcement are formed.

[0031] Since any mechanism for the sliding door supported by the frame member (guide rail 13, sliding door 14, automatic closing device 15, and associated members thereof) can be used, detailed description thereof is omitted here. In this embodiment, a double-sliding type sliding door including sliding doors 141 and 142 and equipped with an automatic closing device is taken as an example, but the present invention is not limited to this, and any sliding door can be used.

[0032] Figs. 4 to 11 are explanatory diagrams for explaining a construction method of installing the frame members (vertical frame 11 and blind 12) of the sliding door unit 1. Although the arrangement relationship is reversed left and right compared with Figs. 1 to 3, this does not cause a conceptual difference.

[0033] First, an operation of installing the vertical frame 11 on the wall surface (side panel 2S2) on the side of the opening G is performed. In this embodiment, a C-channel (vertical frame base material) 111 is used to install the vertical frame 11 on the wall surface (side panel 2S2). Also, a C-channel 112 is used as a floor fixing member to prevent the vertical frame 11 from swaying (swaying around the attachment portion to the wall surface).

[0034] FIG. 4 is an explanatory view regarding the attachment of the C-channel 111 which is a vertical frame base material, FIG. 4(a) is a perspective view seen from the indoor side of the toilet booth, and FIG. 4(b) is a cross-sectional view. As shown in FIG. 4, the C-channel 111 is fixed by being screwed with a plurality of screws to the side panel 2S2 which is the side part of the opening G. FIG. 5 is an explanatory view regarding the attachment of the C-channel 112 which is a floor fixing member, FIG. 5(a) is a perspective view seen from the indoor side of the toilet booth, FIG. 5(b) is an enlarged view of the lower end part of FIG. 5(a), and FIG. 5(c) is a cross-sectional view. As shown in FIG. 5, the C-channel 112 is arranged in a direction orthogonal to the wall surface of the side panel 2S2, with one end engaged with the C-channel 111, and is fixed by being screwed to the floor surface.

[0035] FIGS. 6 and 7 are explanatory views regarding the attachment of the vertical frame 11, FIGS. 6(a) and 7(a) are perspective views seen from the indoor side of the toilet booth, and FIGS. 6(b) and 7(b) are cross-sectional views. As shown in FIGS. 6 and 7, the vertical frame 11 is slid toward the wall surface (side panel 2S2) so that the vertical frame 11 is engaged with the C-channel 111 and the C-channel 112. Since each member has the configuration as described above, the workability of this work is excellent, and the vertical frame 11 can be engaged with the C-channel 111 and the C-channel 112 without rattling. Note that at the lower end part of the vertical frame 11, the side surface 115 of the vertical frame 11 is cut out, and when the vertical frame 11 is slid and engaged, the side surface 115 does not become an obstacle to the engagement with the C-channel (floor fixing member) 112 at the lower part of the vertical frame 11. After sliding and engaging the vertical frame 11 with the C-channel 111 and the C-channel 112, as shown in FIG. 7, the vertical frame 11 is fixed to the C-channel (vertical frame base material) 111 by screwing the vertical frame 11 and the C-channel 111 with a plurality of screws. Note that the vertical frame 11 and the C-channel (floor fixing member) 112 may also be fixed by screwing or the like.

[0036] Figs. 8 to 11 are explanatory views regarding the attachment of the blind 12. Specifically, Fig. 8 is a perspective view seen from the indoor side of the toilet booth, Fig. 9(a) is an enlarged front view of the joint portion between the vertical frame 11 and the blind 12, Fig. 9(b) is a longitudinal sectional view of the same portion, Fig. 10 is a perspective view seen from the indoor side of the toilet booth, Fig. 11(a) is an enlarged perspective view of the joint portion between the vertical frame 11 and the blind 12, Fig. 11(b) is an enlarged front view of the joint portion between the vertical frame 11 and the blind 12, and Fig. 11(c) is a longitudinal sectional view of the same portion. As described above, an upper frame load receiving portion 113 is provided at the upper part of the vertical frame 11, and the upper frame load receiving portion 113 is inserted into the inside of the beam portion 121 of the blind 12 which is a hollow member (see Figs. 8 and 9). Thereby, since one end side of the blind 12 can be supported by the upper frame load receiving portion 113, the workability of attaching the blind 12 is excellent. Further, since the upper frame load receiving portion 113 is attached at a predetermined height based on the design in advance, the blind 12 can be arranged at an accurate height. With one end side of the blind (upper frame) 12 supported by the upper frame load receiving portion 113, the blind (upper frame) 12 is installed above the opening G. More specifically, with one end side of the blind 12 hooked on the frame load receiving portion 113, while supporting the other part of the blind 12 by hand and leveling the blind 12, the mounting plate 122 of the blind 12 is screwed to the wall surface (upper panel 2T) with a plurality of screws SC (Fig. 10). Even a single operator can perform the work relatively easily. Note that a cushioning material sheet (PVC sheet in this embodiment) for absorbing the influence of small irregularities, steps, etc. (such as steps generated at the end portions of each panel body) of the wall surface (panel body) is pre - attached to the back surface side of the mounting plate 122, and the PVC sheet is disposed between the mounting plate 122 and the wall surface. As shown in Fig. 11, by fastening the blind (upper frame) 12 to the upper frame load receiving portion 113 with screws SC, the installation of the vertical frame 11 and the blind 12 is completed. When screwing the upper frame load receiving portion 113 and the blind 12, by joining them so that there is no gap between the side surface of the blind 12 and the side surface of the vertical frame 11, the vertical frame 11 can be installed closer to being perpendicular to the wall surface.

[0037] As described above, according to the sliding door unit 1 and its construction method of the present embodiment, since one end side of the mullion 12 can be supported by the upper frame load receiving portion 113, the workability of attaching the mullion 12 is excellent. The mullion 12 can be a long member according to the size of the opening G or the like, and the work of installing it at a predetermined height (relatively high position) while leveling it horizontally tends to be a complicated work. However, according to the present embodiment, the workability is excellent and even one person can easily perform the work. As a result, even in a relatively narrow work space such as a toilet booth, the workability of installing the frame member for providing the sliding door is excellent and even one person can easily perform the work. In addition, since the upper frame load receiving portion 113 is attached to a predetermined height based on the design in advance, the mullion 12 can also be arranged at an accurate height. Note that "the upper frame load receiving portion 113 is attached to the vertical frame 11 in advance" includes not only the case where the upper frame load receiving portion 113 is attached to the vertical frame 11 at the time of factory shipment, but also, for example, the case where the upper frame load receiving portion 113 is attached to the vertical frame 11 at the construction site (at least before the attachment work of the mullion 12).

[0038] When attaching the mullion, as another configuration for simplifying the holding of the mullion, the mullion may be hooked on a fastening body such as a screw provided on the wall surface. More specifically, in the upper part of the opening, within the range where the mullion (upper frame) is installed, a step of providing a fastening body with a part protruding from the wall surface (for example, driving a screw with the screw head protruding from the wall surface), A construction method may be provided that includes a step of installing the upper frame at the upper part of the opening after hooking the hanger part of the mullion (upper frame) on a part of the fastening body, with the mullion (upper frame) having a hanger part. FIG. 12 is a diagram related to the construction method, and is a longitudinal sectional view showing a state where the mullion 12 is installed on the wall surface (upper panel 2T) above the opening G. A hanger part 123 is formed as a recess on the surface of the beam part 121 of the mullion 12 facing the wall surface. Drive one or more screws SC into the position on the wall surface (upper panel 2T) that faces the hanger portion 123, and hook the hanger portion 123 onto the protruding portion of the screw SC from the wall surface to support the blind 12. In this state, screw the mounting plate 122 of the blind 12 to the wall surface. According to this, even when the vertical frame is not provided, the workability of installing the blind can be improved. Of course, it may be used in combination when the vertical frame is provided (when using the upper frame load receiving portion). Here, the hanger portion 123 is taken as an example of a concave portion, but the present invention is not limited to this, and it can be any configuration that can be hooked on a part of the fastening body protruding from the wall surface. For example, a hole large enough to allow a part of the fastening body to pass through the blind 12 may be formed as the hanger portion. Also, although a screw is taken as an example of the fastening portion, the present invention is not limited to this (for example, a nail may be used).

[0039] When partitioned by a panel body, such as in a toilet booth, there may be a case where there is no panel body (open) at the upper part of the opening. Without an upper panel or lintel, etc., the blind cannot be installed. Therefore, a method of providing a panel body (intercolumn panel) at the upper part of the opening so that the blind can be installed when the upper part of the opening is open will be described.

[0040] Figs. 13 to 16 are explanatory views regarding the attachment of the intercolumn panel. Figs. 13 and 14 are cross-sectional views of the open portion O at the upper part of the opening of the toilet booth, Fig. 15 is a cross-sectional view of the state where the intercolumn panel is attached at the same location, and Fig. 16 is a front view. In this method, an intercolumn panel 172 having slide engaging portions 171 attached to both ends of the open portion O at the upper part of the opening and engaged portions 1721 that engage with the slide engaging portions 171 at both ends is used. The slide engaging portion 171 is a square pipe-shaped member and has a thickness approximately half of the thickness of the panel body (side panels 2S1, 2S2). The mullion panel 172 is basically a panel body similar to the side panels 2S1 and 2S2, and engaging portions 1721, which are recesses for receiving the slide engaging portions 171, are formed on both end faces thereof. As shown in FIG. 13, when there is no panel body at the upper part of the opening and it is an open part O, the slide engaging portions 171 are attached to both ends of the open part O (that is, the end faces of the side panel 2S1 and the side panel 2S2) (FIG. 14). Next, after applying an adhesive to one or both of the slide engaging portion 171 and the engaged portion 1721, the mullion panel 172 is slid upward from below so that the engaged portion 1721 is engaged with the slide engaging portion 171. When the mullion panel 172 is disposed at a predetermined position, screws are driven through both the slide engaging portion 171 and the engaged portion 1721 within the range where the flush (upper frame) 12 is installed (screw SC in FIGS. 15 and 16). Note that the fastening member for fastening the slide engaging portion 171 and the engaged portion 1721 is not limited to a screw (it may be a nail or the like). Further, the fastening member is for holding the mullion panel 172 until the adhesive cures, and is not essential. Thereby, the mullion panel 172 is fixed to the upper part of the opening, and a flush (upper frame) can be installed with respect to the mullion panel 172. According to the above method, since it is possible to prevent the members for installing the mullion panel from appearing on the design surface, the design is excellent. Note that it is more preferable to install the fastening member that penetrates both the slide engaging portion 171 and the engaged portion 1721 as the fastening member for hooking the hanger portion 123 described with reference to FIG. 12.

[0041] In the case of the configuration in which the upper frame load receiving portion 113 is provided so as to protrude from the side surface of the vertical frame 11 and is inserted into the hollow flush 12 (beam portion 121) as in the present embodiment, the vertical frame 11 cannot be removed unless the flush 12 is removed. In this case, when the vertical frame is deformed or damaged due to an object hitting it or the like, it is essential to remove the flush when attempting to replace the vertical frame. FIG. 17 shows a configuration that enables the replacement of the vertical frame without the need for the removal of the blind in such a case. In the blind 12 shown in FIG. 17, a slit 124 is formed to allow the upper frame load receiving portion 113 (a member for supporting the blind) to pass through, so that the vertical frame 11 can be slid in a direction away from the opening wall surface and removed. As a result, as shown in FIG. 17(b), by removing the screw SC that fastens the upper frame load receiving portion 113 and the blind 12, and the screw that fastens the vertical frame 11 to the C-channel (vertical frame base material) 111, the vertical frame 11 can be slid forward (in a direction away from the wall surface) and removed without the need for the removal of the blind 12.

[0042] In the embodiment, an example is given where the upper frame load receiving portion is configured by attaching an L-shaped member (angle member). However, the present invention is not limited to this, and any member having a shape capable of supporting the blind (upper frame) can be used. Also, in the embodiment, the upper frame load receiving portion is provided so as to protrude from the side surface of the vertical frame and is inserted into the hollow blind. However, the present invention is not limited to this. For example, a portion protruding toward the blind (upper frame) may be provided and supported by a hole (or upper end portion) provided in the vertical frame. In this case, the hole (or upper end portion) in the vertical frame corresponds to the "upper frame load receiving portion provided in the vertical frame". In the case of a configuration where a portion protruding toward the blind is provided and inserted into a hole provided in the vertical frame, the "slit" described in FIG. 17 will be provided in the vertical frame.

[0043] In the embodiment, the installation location of the sliding door unit is described by taking a toilet booth as an example. However, the installation target of the sliding door unit according to the present invention is not limited to this, and it can be used for any opening (an opening formed in a wall or partition for separating a "predetermined space" such as a room).

[0044] In this embodiment, the example is given where the vertical frame is installed on the wall surface via a C-channel (vertical frame base material). However, the present invention is not limited to this. For example, the vertical frame base material may be constituted by members of other shapes and installed on the wall surface, or the vertical frame may be directly attached to the wall surface (without using a vertical frame base material). Similarly, in this embodiment, the example is given where a C-channel is used as a floor fixing member to prevent the vertical frame from swaying. However, the present invention is not limited to this. For example, members of other shapes may be used as the floor fixing member, or the vertical frame may be directly fixed to the floor surface. Note that the configuration for preventing swaying such as the floor fixing member is not essential.
