Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in conventional assembled shower units, the door body could not be folded, or the door could be folded but the outer frame could not be folded. Therefore, it was difficult to transport the shower unit in a compact state to disaster-stricken areas and the like.

[0006] Furthermore, since at least a part of the outer frame was made of synthetic resin, the door body was lacking in robustness.

[0007] The present invention has been made in view of the above-described technical background, and an object of the present invention is to provide an entrance door for an assembled shower unit and an assembled shower unit that can be made compact and have high robustness. [Means for solving the problem]

The hinge frame of the framed door is pivotally attached to the outer hinge frame of the outer frame, thereby allowing the framed door to be opened and closed within the outer frame. The door body is an entrance door for an assembly-type shower unit that can be folded vertically relative to the outer frame when the frame door is closed.

[0010] 2) A metal intermediate frame is provided at approximately the midpoint in the vertical direction of the framed door. The position approximately midway in the vertical direction of the aforementioned middle frame is the position of the fold line of the door body, and the aforementioned middle frame is divided into an upper middle frame and a lower middle frame by the fold line. The portions of the door body located above and below the fold line are defined as the upper half of the door and the lower half of the door, respectively. The portions of the framed door located above and below the fold line are defined as the upper half of the framed door and the lower half of the framed door, respectively. The portions of the outer frame located above and below the fold line are defined as the upper half of the outer frame and the lower half of the outer frame, respectively. When one of the two surfaces of the door body in the thickness direction is designated as the first surface and the other as the second surface, An upper frame, an upper door frame, an upper hinge frame, and an upper middle frame are provided around the four sides of the upper half of the framed door. The lower half of the framed door is provided with a bottom frame, a lower door frame, a lower hinge frame, and the lower middle frame around all four sides. The upper half of the outer frame comprises an outer upper frame, an outer upper door frame, and an outer upper hinge frame. The aforementioned lower half of the outer frame has an outer lower frame, an outer lower door frame, and an outer lower hinge frame, The upper middle frame and the lower middle frame of the framed door, the outer upper door frame and the outer lower door frame of the outer frame, and the outer upper hinge frame and the outer lower hinge frame of the outer frame are each connected to one another via hinges provided on the first surface. The door body is foldable so that the opening angle between the upper and lower halves of the door is 180°, and can be folded around the hinge so that the opening angle is 0°. The upper half of the door and the lower half of the door are arranged such that when the opening angle is 180°, the lower end surface of the upper half of the door and the upper end surface of the lower half of the door collide, thereby restricting the opening angle from increasing beyond 180°.

[0014] 6) An assembled shower unit provided with an entrance / exit door, An assembled shower unit in which the entrance / exit door described in any one of paragraphs 1 to 5 above is used as the entrance / exit door.

Advantages of the Invention

[0015] The present invention has the following effects.

[0016] In paragraph 1 above, since the door body can be folded up and down in the state where the sash door is closed with respect to the outer frame, the door body can be made compact.

[0017] Furthermore, since the sash and the outer frame of the sash door in the door body are made of metal, the door body has high robustness.

[0018] In the above item 2, the upper half of the door and the lower half of the door are regulated so that when the opening angle is 180°, the lower end surface of the upper half of the door and the upper end surface of the lower half of the door abut against each other, preventing the opening angle from increasing beyond 180°. Further, the upper middle frame and the lower middle frame in the frame door, the outer upper door end frame and the outer lower door end frame in the outer frame, and the outer upper hanging frame and the outer lower hanging frame in the outer frame are respectively configured to be connected to each other by the patch lock provided on the second surface so that the opening angle does not decrease beyond 180° when the opening angle is 180°.

[0019] Therefore, when folding the door body, the door body can be folded by releasing the patch lock. When making the folded door body usable as an entrance door, the door body can be held in a state where the opening angle is 180° by unfolding the door body to a state where the opening angle is 180° and locking the patch lock.

[0020] In the above item 3, the first fitting convex portions are formed on the outer upper door end frame and the outer lower door end frame in the outer frame, and the second fitting convex portions are formed on the outer upper hanging frame and the outer lower hanging frame in the outer frame. Therefore, by fitting the first fitting convex portion and the second fitting convex portion into the first fitting concave portion of the first corner column and the second fitting concave portion of the second corner column of the shower unit respectively, the door body can be easily and firmly incorporated into the shower unit as a wall member provided with an entrance door in the assembled shower unit.

[0021] In the above item 4, when the frame door is closed with respect to the outer frame, the first magnet body is adsorbed to the first magnet adsorption portion, and / or the second magnet body is adsorbed to the second magnet adsorption portion. Thereby, the state of closing the frame door with respect to the outer frame can be firmly held.

[0022] In the above item 5, the door body can be folded so that the handle member does not interfere.

[0023] In the above item 6, an assembled shower unit having the above effects of the door body can be provided.

[Modes for carrying out the invention]

[0025] One embodiment of the present invention is described below with reference to the drawings.

[0026] An entrance door for an assembly-type shower unit according to one embodiment of the present invention comprises a door body 1 shown in Figures 1A to 2B. The door body 1 is used as the entrance door 81 of the assembly-type shower unit 80 shown in Figure 3. More specifically, the shower unit 80 is a rectangular box-shaped structure comprising a front wall on which the entrance door 81 is provided, a pair of left and right side walls 82 and 83, and a rear wall (not shown), and the door body 1 is incorporated into the shower unit 80 as the front wall.

[0027] As shown in Figures 1A and 2A, the door body 1 comprises a framed door 10 and a roughly rectangular outer frame 30 corresponding to the framed door 10. The framed door 10 has a frame 11 on all four sides. The frame 11 is entirely made of a metal such as aluminum (including its alloys; the same applies hereinafter). The outer frame 30 is also entirely made of a metal such as aluminum (including its alloys; the same applies hereinafter). Specifically, the frame 11 and the outer frame 30 are made of aluminum extruded profiles or the like.

[0028] As shown in Figure 1A, the framed door 10 is pivotally attached to the outer hinge frame 34 of the outer frame 30 via two main hinges 3, 3, with its hinge frame 16 being attached via two main hinges 3, 3, one above the other. This connects and integrates the framed door 10 with the outer hinge frame 34 of the outer frame 30 so that it can be opened and closed within the outer frame 30. Furthermore, as shown in Figure 6, the door body 1 is configured to be foldable in half vertically relative to the outer frame 30 when the framed door 10 is closed.

[0029] Next, the configuration of the door body 1 will be described in detail below.

[0030] As shown in Figures 1A to 2B, a metal middle frame 13 made of aluminum or the like is provided at approximately the midpoint in the vertical direction of the framed door 10, extending horizontally (left and right). The midpoint in the vertical direction of the middle frame 13 is at the position of the fold line P of the door body 1, and the middle frame 13 is divided into an upper middle frame 13A and a lower middle frame 13B at this fold line P.

[0031] Here, the parts of the door body 1 located above and below the fold line P are designated as the upper door half 1A and the lower door half 1B, respectively. Similarly, the parts of the framed door 10 located above and below the fold line P are designated as the upper framed door half 10A and the lower framed door half 10B, respectively. Similarly, the parts of the outer frame 30 located above and below the fold line P are designated as the upper framed frame half 30A and the lower framed frame half 30B, respectively. Furthermore, one surface F and the other surface R of the two surfaces in the thickness direction of the door body 1 (i.e., the framed door 10 and the outer frame 30) are designated as the first surface F and the second surface R, respectively.

[0032] The upper half of the framed door 10A is surrounded by an upper frame 12, an upper door front frame 15A, an upper hinge frame 16A, and the aforementioned upper middle frame 13A, with a rectangular panel 18A, made of synthetic resin or metal, fitted inside these. The thickness of the panel 18A is thinner than that of the frame 11.

[0033] The lower half of the framed door 10B is surrounded by a bottom frame 14, a lower door front frame 15B, a lower hinge frame 16B, and the aforementioned lower middle frame 13B. Inside these, a rectangular panel 18B made of, for example, synthetic resin or metal is fitted. The thickness of the panel 18B is thinner than that of the frame 11.

[0034] The upper half of the outer frame 30A consists of the outer upper frame 31, the outer upper door frame 33A, and the outer upper hinge frame 34A.

[0035] The lower half of the outer frame 30B consists of the outer lower frame 32, the outer lower door frame 33B, and the outer lower hinge frame 34B.

[0036] The upper middle frame 13A and lower middle frame 13B of the framed door 10, the outer upper door end frame 33A and outer lower door end frame 33B of the outer frame 30, and the outer upper hinge frame 34A and outer lower hinge frame 34B of the outer frame 30 are each connected to one another via hinges 40 with a movable range of 0° to 180° provided on the first surface F. In this embodiment, the first surface F on which the hinges 40 are provided is the front surface F of the door body 1 (framed door 10 and outer frame 30).

[0037] More specifically, as shown in Figure 1A, the number of hinges 40 connecting the upper middle frame 13A and the lower middle frame 13B in the framed door 10 is one or more, specifically two. These hinges 40 connect the upper middle frame 13A and the lower middle frame 13B at positions spaced apart from each other along the length of the upper middle frame 13A and the lower middle frame 13B.

[0038] As shown in Figure 1B, each hinge 40 has two wings 41, 41 formed on both sides of its shaft portion 42. With the shaft portion 42 of the hinge 40 positioned at the fold line P, one wing 41 and the other wing 41 are fixed to the front surface F of the upper middle frame 13A and the front surface F of the lower middle frame 13B of the framed door 10 by known fastening means (in this embodiment, screws 44 are used for fastening; the same applies hereinafter). As a result, the framed door 10 is configured to be foldable in half around the hinge 40 (more specifically, the shaft portion 42 of the hinge 40; the same applies hereinafter) so that its front surface F side faces inward.

[0039] Similarly, one wing 41 and the other wing 41 of the hinge 40 are fixed to the front surface F of the lower end of the outer upper door frame 33A and the front surface F of the upper end of the outer lower door frame 33B of the outer frame 30 by known fastening means, with the shaft portion 42 of the hinge 40 positioned at the fold line P. Furthermore, one wing 41 and the other wing 41 of the hinge 40 are fixed to the front surface F of the lower end of the outer upper hinge frame 34A and the front surface F of the upper end of the outer lower hinge frame 34B of the outer frame 30 by known fastening means, with the shaft portion 42 of the hinge 40 positioned at the fold line P. As a result, the outer frame 30 is configured to be foldable in half around the hinge 40 so that its front surface F side faces inward.

[0040] Therefore, the door body 1, which includes a framed door 10 and an outer frame 30, is configured to be foldable in half around the hinge 40 so that the front side F of the door body 1 faces inward when the framed door 10 is closed relative to the outer frame 30. In other words, the door body 1 can be folded from a state where the opening angle θ (see Figures 7 and 8) between the upper half of the door 1A and the lower half of the door 1B is 180° to a state where the opening angle θ is 0° by folding it around the hinge 40.

[0041] As shown in Figure 7, when the folded door body 1 is unfolded and ready to be used as an entrance door 81, that is, when the opening angle θ is 180°, the lower end surface 8 of the upper door body 1A and the upper end surface 9 of the lower door body 1B are in contact with each other. Thus, the opening angle θ of the upper door body 1A and the lower door body 1B is restricted so as not to exceed 180°.

[0042] Furthermore, the door body 1 is configured such that, when the opening angle θ is 180°, the upper middle frame 13A and lower middle frame 13B of the framed door 10, the outer upper door end frame 33A and outer lower door end frame 33B of the outer frame 30, and the outer upper hinge frame 34A and outer lower hinge frame 34B of the outer frame 30 are connected to each other via a snap lock 50 provided on the second surface R, so as not to decrease the opening angle θ from 180°. In this embodiment, the second surface R on which the snap lock 50 is provided is the rear surface R of the door body 1 (framed door 10 and outer frame 30).

[0043] More specifically, as shown in Figure 2A, the number of latches 50 connecting the upper middle frame 13A and the lower middle frame 13B in the framed door 10 is one or more, specifically two. When the opening angle θ is 180°, these latches 50 connect the upper middle frame 13A and the lower middle frame 13B at positions spaced apart from each other in the longitudinal direction of the upper middle frame 13A and the lower middle frame 13B.

[0044] As shown in Figure 2B, each snap lock 50 comprises one lock component 51 having a hook portion 52, and the other lock component 55 having an annular (approximately square annular in this embodiment) locking piece 56 and a lever piece 57 that are detachably locked to the hook portion 52. The one lock component 51 and the other lock component 55 are then fixed to the rear surface R of the upper middle frame 13A and the rear surface R of the lower middle frame 13B of the framed door 10 by known fastening means.

[0045] Specifically, one lock component 51 is fixed to the rear surface R of the upper middle frame 13A by screw fastening with a screw 58, and the other lock component 55 is fixed to the rear surface R of the lower middle frame 13B by screw fastening with a screw 58. When the opening angle θ is 180°, as shown in Figure 7, the locking piece 56 of the other lock component 55 is locked to the hook portion 52 of the one lock component 51, and the lever piece 57 is tilted, thereby maintaining the locking state of the locking piece 56 to the hook portion 52. In this way, the upper middle frame 13A and the lower middle frame 13B are connected to each other via the snap lock 50 so that the opening angle θ does not decrease below 180°.

[0046] Similarly, when the opening angle θ is 180°, the lower end of the outer upper door frame 33A and the upper end of the outer lower door frame 33B on the outer frame 30 are connected to each other via a latch 50 provided on the rear surface R so as not to reduce the opening angle θ to less than 180°. Furthermore, similarly, when the opening angle θ is 180°, the lower end of the outer upper hinge frame 34A and the upper end of the outer lower hinge frame 34B on the outer frame 30 are connected to each other via a latch 50 provided on the rear surface R so as not to reduce the opening angle θ to less than 180°.

[0047] Therefore, when the framed door 10 is closed relative to the outer frame 30 and the opening angle θ is 180°, the upper half of the door 1A and the lower half of the door 1B are connected to each other via a latch 50 provided on the rear surface R so that the opening angle θ does not decrease below 180°. The door body 1 is constructed in this manner.

[0048] As shown in Figures 1A and 2A, a first fitting projection 36 that protrudes outward is integrally formed along the outer upper door frame 33A and outer lower door frame 33B of the outer frame 30 of the door body 1.

[0049] On the other hand, as shown in Figure 3, in the shower unit 80, a first corner post 84 made of metal such as aluminum, extending vertically, is positioned at the first corner between the door body 1 and the first side wall 82 located on the door edge side of the door body 1. As shown in Figure 4(a), the first corner post 84 is made of an aluminum extruded profile or the like with a roughly L-shaped cross-section, and a first fitting recess 85 is formed along the side end face of the first corner post 84. When the door body 1 is assembled into the shower unit 80, the first fitting projection 36 is fitted into the first fitting recess 85 in a removable manner.

[0050] Similarly, as shown in Figures 1A and 2A, a second fitting projection 37, having the same cross-sectional shape as the first fitting projection 36, is integrally formed along the outer end faces of the outer upper hinge frame 34A and outer lower hinge frame 34B of the outer frame 30 of the door body 1, projecting outward.

[0051] On the other hand, as shown in Figure 3, in the shower unit 80, a second corner support 86 made of metal such as aluminum, extending in the vertical direction, is positioned at the second corner between the door body 1 and the second side wall 83 located on the hinge side relative to the door body 1. As shown in Figure 4(b), the second corner support 86 is made of an aluminum extruded profile or the like with a roughly L-shaped cross-section, and a second fitting recess 87 is formed along the side end face of the second corner support 86. When the door body 1 is assembled into the shower unit 80, the second fitting projection 37 is fitted into the second fitting recess 87 in a removable manner.

[0052] Furthermore, as shown in Figures 1A and 2A, a third fitting projection 38, which has the same cross-sectional shape as the first and second fitting projections 36 and 37, is integrally formed along the outer upper frame 31 of the outer frame 30 of the door body 1, protruding outward.

[0053] On the other hand, as shown in Figure 3(b), in the shower unit 80, a metal upper rail 88 made of aluminum or the like is positioned horizontally (left-right) on the upper side of the door body 1. The upper rail 88 is made of an aluminum extruded profile or the like, and a third fitting recess (not shown) having the same cross-sectional shape as the first and second fitting recesses 85 and 87 is formed along the lower end surface of the upper rail 88. When the door body 1 is assembled into the shower unit 80, the third fitting projection 38 is fitted into the third fitting recess in a removable manner.

[0054] Therefore, the door body 1 can be easily and securely incorporated into the shower unit 80 as a wall member provided with the entrance door 81 in the assembled shower unit 80.

[0055] As shown in Figures 5A and 5B, in the state in which the framed door 10 is closed to the outer frame 30, on the upper part of the outer upper door frame 33A or on the upper part of the upper door frame 15A or on the mutually opposing surfaces of the outer upper frame 31 and the upper door frame 12, a plate-shaped first magnet body 61 is fixed to one opposing surface by known fastening means such as screws, and on the other opposing surface, a first magnetic adsorption part 62 made of a plate-shaped ferromagnetic material to which the first magnet body 61 is attracted is fixed by known fastening means such as screws.

[0056] Similarly, in the state in which the framed door 10 is closed relative to the outer frame 30, on the mutually opposing surfaces between the lower part of the outer lower door frame 33B and the lower part of the lower door frame 15B, a plate-shaped second magnet body 63 is fixed to one opposing surface by known fastening means such as screws, and a second magnetic adsorption part 64 made of a plate-shaped ferromagnetic material to which the second magnet body 63 is attracted is fixed to the other opposing surface by known fastening means such as screws (see Figures 1A and 2A).

[0057] Neodymium magnets, ferrite magnets, etc., can be used as the first and second magnetic bodies 61 and 63. Examples of ferromagnetic materials include iron (including its alloys; the same applies hereinafter), cobalt (including its alloys; the same applies hereinafter), nickel (including its alloys), etc.

[0058] These components can be explained in detail as follows:

[0059] As shown in Figures 2A and 5A, on the inner edges of the rear R side of the outer upper frame 31, outer door frame 33 (outer upper door frame 33A, outer lower door frame 33B), and outer hinge base frame 34 (outer upper hinge base frame 34A, outer lower hinge base frame 34B) of the outer frame 30, inwardly protruding receiving plates 31a, 33Aa, 33Ba, 34Aa, and 34Ba are integrally formed along these frames. These receiving plates support the frame 11 of the closed door 10 from the rear R side relative to the outer frame 30, thereby restricting the door 10 to the closed position.

[0060] When the framed door 10 is closed relative to the outer frame 30, the upper front surface (i.e., receiving surface) F of the receiving plate 33Aa of the outer upper door frame 33A and the upper front surface (i.e., receiving surface) F of the receiving plate 31a of the outer upper frame 31 face each other, as do the upper rear surface R of the upper door frame 15A and the rear surface R of the upper frame 12 of the framed door upper half 10A.

[0061] Furthermore, on these opposing surfaces, the first magnet body 61 is fixed by screwing to the upper front surface (receiving surface) F of the receiving plate 33Aa of the outer upper door frame 33A, which is one of the opposing surfaces, so that the shower user can see the presence of the first magnet body 61 when the framed door 10 is opened, and the first magnetic adsorption part 62 is fixed by screwing to the upper rear surface R of the upper door frame 15A, which is the other opposing surface.

[0062] In this invention, the first magnetic adsorption part 62 may be fixed to the upper front surface (receiving plate) F of the receiving plate 33Aa of the outer upper door frame 33A, and the first magnetic body 61 may be fixed to the upper rear surface R of the upper door frame 15. Alternatively, the first magnetic body 61 or the first magnetic adsorption part 62 may be fixed to the front surface (receiving surface) F of the receiving plate 31a of the outer upper frame 31, which is one opposing surface, and the first magnetic adsorption part 62 or the first magnetic body 61 may be fixed to the rear surface R of the upper frame 12, which is the other opposing surface.

[0063] Similarly, when the framed door 10 is closed relative to the outer frame 30, the lower front surface (receiving surface) F of the receiving plate 33Ba of the outer lower door frame 33B in the lower half of the outer frame 30B and the lower rear surface R of the lower door frame 15B in the lower half of the framed door 10B face each other.

[0064] Furthermore, on these opposing surfaces, the second magnet body 63 is fixed by screwing to the front surface (receiving surface) F of the lower part of the receiving plate 33Ba of the outer lower door frame 33B, which is one of the opposing surfaces, so that the shower user can see the presence of the second magnet body 63 when the framed door 10 is opened, and the second magnetic adsorption part 64 is fixed by screwing to the rear surface R of the lower part of the other opposing surface, the lower door frame 15B.

[0065] In this invention, the second magnetic adsorption part 64 may be fixed to the lower front surface (receiving surface) F of the receiving plate 33Ba of the outer lower door frame 33B, and the second magnetic body 63 may be fixed to the lower rear surface R of the lower door frame 15B.

[0066] As shown in Figure 1A, a spacer member 7 made of synthetic resin is provided protruding from one of the front surfaces F of the outer upper frame 31 and the outer lower frame 32 of the outer frame 30, so as to contact the other front surface F when the door body 1 is folded. In this embodiment, the spacer member 7 is fixed to the front surface F of the outer upper frame 31 by screws or the like.

[0067] As shown in Figure 8, the spacer member 7 forms a gap S between the upper half of the door 1A and the lower half of the door 1B so that the metal handle member 5 (see Figure 1A), which is provided on one of the front surfaces F of the upper half of the door 1A and the lower half of the door 1B, does not come into contact with the other front surface F when the door body 1 is folded.

[0068] The handle member 5 has a portion on which the shower user grips when opening and closing the framed door 10 from its front side F in the shower unit 80. In this embodiment, the handle member 5 is fixed to the front side F of the upper middle frame 13A of the upper half of the door 1A. The protruding height of the spacer member 7 is set to correspond to the height of the handle member 5.

[0069] In Figure 2A, the reference numeral "6" indicates a metal slide lock that locks the framed door 10 to the outer frame 30 in a releaseable manner when the door is closed. This slide lock 6 is fixed to the rear surface R of the upper middle frame 13A of the upper half of the door 1A at a position opposite to the handle member 5 by known fastening means such as screws.

[0070] In the entrance door 81 of this embodiment, when folding the door body 1, the frame door 10 is closed to the outer frame 30, and preferably the frame door 10 is locked in the closed position by the slide lock 6. In this state, the opening angle θ of the door body 1 is 180°. Then, all latches 50 are released.

[0071] Next, as shown in Figure 6, the door body 1 is folded in half by bending it around the hinge 40 with its front side F facing inward. As a result of this folding operation, the hinge 40 is also folded in half.

[0072] In this folded state of the door body 1, as shown in Figure 8, the spacer member 7 (more specifically, the tip surface of the spacer member 7) comes into contact with the front surface F of the outer lower frame 32 of the lower half of the door 1B. As a result, a gap S is formed between the upper half of the door 1A and the lower half of the door 1B, preventing the handle member 5 from coming into contact with the front surface F of the lower half of the door 1B (more specifically, the front surface F of the lower middle frame 13B of the lower half of the door 1B), i.e., preventing interference between the handle member 5 and the front surface.

[0073] Furthermore, in this folded state, the opening angle θ is 0° due to the thickness of the hinge 40 when folded in half and the protruding height of the spacer member 7. In other words, the thickness of the hinge 40 when folded in half and the protruding height of the spacer member 7 are set so that the opening angle θ is 0° when the door body 1 is folded.

[0074] The door body 1 is transported in this folded state. Here, since the frame 11 and outer frame 30 of the framed door 10 are all made of metal, the door body 1 has high robustness, and therefore, deformation, damage, etc. of the door body 1 during transport can be suppressed.

[0075] When unfolding the folded door body 1, the upper half of the door 1A is rotated around the hinge 40 relative to the lower half of the door 1B so that the opening angle θ increases from 0°. When the opening angle θ reaches 180° (i.e., the door body 1 is unfolded), the lower end surface 8 of the upper half of the door 1A and the upper end surface 9 of the lower half of the door 1B come into contact, as shown in Figure 7. This restricts the unfolding movement of the upper half of the door 1A and the lower half of the door 1B so that the opening angle θ does not increase beyond 180°.

[0076] Next, all the latches 50 are locked. This connects the upper half of the door 1A and the lower half of the door 1B to each other via the latches 50, so that the opening angle θ does not decrease below 180° and the opening angle θ is maintained at 180°.

[0077] Next, the door body 1 is incorporated into the shower unit 80 as a wall member on which the entrance door 81 of the assembled shower unit 80 is provided. In this assembled state, since the frame 11 and outer frame 30 of the framed door 10 are all made of metal, the shower unit 80 has high robustness. Moreover, as shown in Figure 4, the first and second fitting protrusions 36 and 37 of the outer frame 30 of the door body 1 are fitted into the first and second fitting recesses 85 and 87 of the corresponding first and second corner posts 84 and 86, respectively, so the shower unit 80 has even higher robustness. Furthermore, since the third fitting protrusion 38 of the outer upper frame 31 is fitted into the third fitting recess of the upper rail 88, the robustness of the shower unit 80 is further enhanced.

[0078] Furthermore, the door body 1 is incorporated into the shower unit 80 by fitting the first to third fitting protrusions 36, 37, and 38 into the corresponding first to third fitting recesses 85 and 87, so the door body 1 can be easily incorporated into the shower unit 80.

[0079] Furthermore, in the door body 1 incorporated into the shower unit 80, when the framed door 10 is closed relative to the outer frame 30, the first and second magnetic bodies 61 and 63 are attracted to the corresponding first and second magnetic adsorption parts 62 and 64, respectively, so that the framed door 10 can be firmly held closed relative to the outer frame 30. In addition, the following advantages are available.

[0080] In other words, as in the door body 1 of this embodiment, if the framed door 10 is divided into an upper framed door 10A and a lower framed door 10B, and is held in place by the latch 50 alone so that the opening angle θ does not decrease to less than 180°, then a shower user (especially a female shower user) who is aware of this may feel that if they intentionally hook their fingertips or other body onto the upper corner of the upper framed door 10A on the door-side or the lower corner of the lower framed door 10B on the door-side and pull it strongly forward from the outside of the framed door 10, the pulled upper or lower corner will bend slightly forward, creating a gap between it and the outer frame 30, and the inside of the shower unit 80 will be visible through this gap.

[0081] However, since the first and second magnetic bodies 61 and 63 are attracted to the corresponding first and second magnetic adsorption parts 62 and 64, respectively, the shower user is given the impression that the framed door 10 is firmly held in the closed position, and the shower user can feel at ease knowing that such a problem will not occur.

[0082] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified in various ways without departing from the spirit of the invention.

[0083] For example, the present invention may use the door body 1 of the above embodiment as an entrance door for an assembly-type toilet unit. [Industrial applicability]

[0084] This invention is applicable to entrance doors for prefabricated shower units and to prefabricated shower units themselves. [Explanation of symbols]
