DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] [Window Panel 10] First, a door structure in which a windowed panel 10 according to one embodiment of the present invention is provided as a door body will be described with reference to Figures 1 to 6. The door structure including the windowed panel 10 according to this embodiment is configured to be openable by rotating the windowed panel 10 towards the front side of the paper in Figure 1. In this specification, the side to which the windowed panel 10 is rotated when opening the door structure will be described as the front of the windowed panel 10. For the windowed panel 10 according to this embodiment, the front side will be described as "one side" and the rear side as "the other side" as appropriate.

[0030] As shown in Figures 1 to 6, a windowed panel 10 according to this embodiment comprises a panel body 1 and a window member 2. The panel body 1 has an opening formed therein that penetrates from one surface, the front surface, to the other surface, the rear surface. A front opening Hf and a rear opening Hr are formed at the front and rear ends of the opening, respectively (see Figure 5). The window member 2 is attached to the opening of the panel body 1 as described below.

[0031] As shown in Figures 1 and 3, a door structure including a window panel 10 is provided between a floor surface F and a ceiling C. The door structure includes a top rail 3, a door end frame 4, a door end frame 5, an upper frame 6, an upper hinge 7, a lower hinge 8, and the window panel 10 which is the door body. A panel member P is provided on the opposite side of the window panel 10 to the door end frame 4 and the door end frame 5. Each element constituting the door structure is mainly made of a steel alloy or an aluminum alloy, except for the window plates (front window plate 22f and rear window plate 22r) provided in the window member 2 of the window panel 10, and the soundproofing material (airtight material 18 and glass wool 19) housed inside the window panel 10.

[0032] 1 to 3, the window panel 10 is rotatably attached to the tail frame 5 and upper frame 6 via an upper hinge 7 and a lower hinge 8. Specifically, the upper end of the window panel 10 on the tail side is connected to the upper frame 6 by the upper hinge 7. Also, the lower end of the window panel 10 on the tail side is connected to the lower end of the tail frame 5 by the lower hinge 8. In this way, the window panel 10 has its rotation center located on the tail frame 5 side, and can be opened and closed between the front frame 4 and the tail frame 5.

[0033] As shown in Figures 2 and 3, the panel body 1 is constructed by holding the outer periphery of a front panel 11f and a rear panel 11r, which are rectangular panel materials, at the front and rear sides of the frame member. The frame member is composed of two outer frames 13 / 13, an upper frame 14, and a lower frame 15. The outer frames 13 / 13 are provided at the trailing end and leading end of the panel body 1, respectively. The upper frame 14 is provided at the upper end of the panel body 1, and the lower frame 15 is provided at the lower end of the panel body 1. A doorknob 16 used when opening and closing the window panel 10 is provided slightly below the vertical center on the leading side of the window panel 10.

[0034] As shown in Fig. 5, the front panel 11f of the panel body 1 has a front opening Hf near the door edge, and the rear panel 11r has a rear opening Hr near the door edge. This forms an opening penetrating the front and rear of the panel body 1 along the longitudinal direction (up-down direction) of the panel body 1. Two adjacent inner frames 12, 12 are provided between the front panel 11f and the rear panel 11r on either side of the opening. As shown in Fig. 2, glass wool 19, which is a sound-proofing material, is accommodated between the inner frame 12 and the outer frame 13 in the internal space of the panel body 1 to prevent sound leakage from the window panel 10.

[0035] As shown in FIG. 3, the window panel 10 has a seal member 17, which is a door bottom, at its lower end. The seal member 17 is provided in the longitudinal direction of the lower frame 15 to close the gap between the lower end of the lower frame 15 and the floor surface F. The seal member 17 has a resin sliding member 17a at its lower part. When the window panel 10 is opened, the seal member 17 is located at the upper part, so that the sliding member 17a is separated from the floor surface F. When the window panel 10 is closed, the seal member 17 is automatically displaced downward, and the sliding member 17a comes into sliding contact with the floor surface F. In this way, the seal member 17 closes the gap between the window panel 10 and the floor surface F, thereby suppressing sound leakage and light leakage below the window panel 10. It is also possible to configure the sliding member 17a to always be in sliding contact with the floor surface F.

[0036] 3, an airtight material 18, which is a sound-proofing material, is accommodated in the rear of the lower frame 15 in the internal space of the panel body 1. The airtight material 18 can further suppress sound leakage below the window panel 10.

[0037] [Window material 2] Next, the window member 2 provided in the window panel 10 according to this embodiment will be described with reference to Figures 1 to 6. As shown in Figure 1, the window member 2 is attached to openings (front opening Hf and rear opening Hr) that are opened in the vertical direction near the door edge of the panel body 1. The window member 2 is formed in the same shape as the openings, a rectangle with its longitudinal direction in the vertical direction.

[0038] 4 to 6, the window member 2 according to this embodiment is configured by combining a front window member 2f which is a one-side window member and a rear window member 2r which is the other-side window member. The front window member 2f is configured by providing a front window plate 22f which is a one-side window plate to a front window frame 21f which is a one-side window frame.

[0039] Specifically, the four sides of the front window plate 22f, which is a rectangular glass plate, are held by four frame members that constitute the front window frame 21f. The ends of the respective frame members are connected by an L-shaped plate 25 as shown in Fig. 4 to form a front window member 2f in which the front window plate 22f is held by the front end portion of the rectangular front window frame 21f. The L-shaped plate 25 is fixed to the frame members of the front window frame 21f in a state where it is inserted into an insertion hole 21a formed in the front window frame 21f as shown in Figs. 5 and 6.

[0040] The rear window member 2r is also configured in the same manner as the front window member 2f, by providing a rear window plate 22r, which is a window plate on the other side, to a rear window frame 21r, which is a window frame on the other side. Specifically, the four sides of the rear window plate 22r, which is a glass plate having the same shape as the front window plate 22f, are held by four frame members that constitute the rear window frame 21r. The ends of each frame member are connected by an L-shaped plate 25 as shown in FIG. 4 to form the rear window member 2r in which the rear window plate 22r is held by the rear end of the rectangular rear window frame 21r. Note that, in addition to glass plates, transparent plates such as acrylic plates, transparent plates with a design sheet attached, hazy glass, and other translucent plate materials can also be used as the front window plate 22f and the rear window plate 22r.

[0041] As described above, in the windowed panel 10 according to this embodiment, the window member 2 comprises a window frame made up of the front window frame 21f and the rear window frame 21r, and window plates (front window plate 22f and rear window plate 22r) provided on the front and rear sides of the window frame. The windowed panel 10 according to this embodiment has a double structure in which the window plates 22f and 22r are provided on the front and rear sides, respectively, thereby ensuring high sound insulation in the window member 2.

[0042] 5, the rear portion of the front window member 2f is inserted from the front side of the panel body 1 into a front opening Hf opened in the front panel 11f and assembled to the panel body 1. Similarly, the front portion of the rear window member 2r is inserted from the rear side of the panel body 1 into a rear opening Hr opened in the rear panel 11r and assembled to the panel body 1.

[0043] As shown in Figures 4 and 5, a connecting recess 21b is formed around the front window plate 22f on the front surface of the front window frame 21f of the front window member 2f. Also, a connected portion 21c is formed on the front end portion of the rear window member 2r. Then, as shown in Figure 6, when the front window member 2f and the rear window member 2r are assembled to the panel body 1, the rear part of the front window member 2f is inserted inside the front part of the rear window member 2r, and the rear surface of the connecting recess 21b comes close to the front surface of the connected portion 21c.

[0044] In this state, a fixing screw 24, which is a fastening member, is inserted into the connecting recess 21b, and the fixing screw 24 is screwed into the bottom surface of the connecting recess 21b and the connected portion 21c. As a result, the front window member 2f and the rear window member 2r are fastened to each other on the front side of the panel body 1. In this embodiment, as shown in Figure 6, a cover member 23 is inserted into the front opening of the connecting recess 21b. As a result, the fixing screw 24 is covered by the cover member 23.

[0045] As described above, in the window panel 10 according to this embodiment, the front window member 2f and the rear window member 2r are fastened with the fixing screws 24 so that their positions are restricted so that they cannot be displaced in the direction away from each other (front-rear direction). In other words, the window member 2 is restricted in position relative to the opening of the panel body 1 so that it cannot fall off.

[0046] As described above, in the window panel 10 of this embodiment, the window member 2 comprising a window frame (front window frame 21f and rear window frame 21r) and window plates (front window plate 22f and rear window plate 22r) is assembled to the opening (front opening Hf and rear opening Hr) of the panel body 1 using fixing screws 24, which are fastening members.

[0047] In this way, the window member 2 can be easily assembled to the opening of the panel body 1, which makes it possible to easily attach / remove the window plates 22f / 22r in the windowed panel 10. Furthermore, in this embodiment, the number of parts around the window plates 22f / 22r is reduced compared to the prior art, thereby improving the work efficiency of attaching / removing the window member 2.

[0048] Furthermore, in the windowed panel 10 according to this embodiment, the front window member 2f of the window member 2 is assembled from the front side to the front opening Hf of the panel body 1, and the rear window member 2r is assembled from the rear side to the rear opening Hr of the panel body 1. This makes it possible to assemble the window members 2 (the front window member 2f and the rear window member 2r) from both the front and rear sides of the panel body 1, thereby improving the ease of assembly of the window member 2 to the panel body 1.

[0049] Furthermore, in the window panel 10 according to this embodiment, the front window member 2f and the rear window member 2r are fastened to each other on the front side of the panel body 1 with fixing screws 24. This allows the fastening work of the window member 2 to be completed only on the front side of the panel body 1 (there is no need to perform fastening work of the window member 2 on both the front and rear sides), further improving the ease of assembly of the window member 2 to the panel body 1.

[0050] In the window panel 10 according to this embodiment, the color and texture of the cover member 23 are formed to be the same as those of the front window frame 21f. Therefore, as shown in Figs. 4 and 6, the design of the front window frame 21f (with the cover member 23 attached) that appears on the front surface of the window member 2 can be made similar to the design of the rear window frame 21r that appears on the rear surface of the window member 2. This allows the impression given to the user of the window panel 10 to be unified between the front and rear, thereby improving the design of the window panel 10. Also, in this embodiment, the apparent dimensions of the front window frame 21f and the rear window frame 21r are made as compact as possible and made common, thereby making it possible to further improve the design of the window panel 10.

[0051] In the windowed panel 10 according to this embodiment, as shown in Fig. 6, the front surface of the panel body 1 is formed so that the front-to-rear position of the surface of the panel body 1 (the front surface of the front panel 11f) and the front surface of the front window plate 22f are substantially the same. In this specification, the term "substantially the same" is used to mean a level at which a user of the windowed panel 10 feels that they are in the same front-to-rear position when visually inspecting them, without any sense of incongruity. Specifically, in this embodiment, "substantially the same" is defined as when the step formed by the surface of the panel body 1 (the front surface of the front panel 11f) and the front surface of the front window plate 22f is within 3 mm.

[0052] Furthermore, in the windowed panel 10 of this embodiment, as shown in Figure 6, the rear surface of the panel body 1 is formed so that the front-to-rear positions of the rear surface of the panel body 1 (the rear surface of the rear panel 11r) and the rear surface of the rear window plate 22r are approximately the same.

[0053] As described above, the windowed panel 10 according to this embodiment is configured so that the front and rear positions (thickness direction positions of the panel body 1) of the surface of the panel body 1 and the surfaces of the front window plate 22f and rear window plate 22r are close to each other on the front and rear surfaces of the panel body 1. This allows the surface of the panel body 1 and the surfaces of the front window plate 22f and rear window plate 22r to be viewed continuously, giving a sophisticated impression to the user of the windowed panel 10.

[0054] That is, in the case of a windowed panel equipped with a single window plate, the step between the panel surface and the surface of the window plate becomes large and the flat feeling is lost, whereas in this embodiment, the flat surfaces between the surface of the panel body 1 and the surfaces of the front window plate 22f and rear window plate 22r are emphasized. This gives the windowed panel 10 a luxurious feel and makes it possible to improve its design.

[0055] In addition, in the window panel 10 according to this embodiment, as shown in Fig. 6, the outer inner peripheral surface 21e located in front of the front window plate 22f in the front window frame 21f, the inner inner peripheral surface 21d located behind the front window plate 22f in the front window frame 21f, the inner inner peripheral surface 21d located in front of the rear window plate 22r in the rear window frame 21r, and the outer inner peripheral surface 21e located behind the rear window plate 22r in the rear window frame 21r are formed to be located on approximately the same plane in each of the top, bottom, left and right directions. As a result, when a user of the window panel 10 visually checks the window member 2, the outer inner peripheral surfaces 21e·21e and the inner inner peripheral surfaces 21d·21d are recognized as being on the same plane. That is, in this embodiment, it is possible to further improve the design of the window panel 10.

[0056] [First modified example] Next, a windowed panel according to a first modified example of the present invention will be described with reference to Figures 7(a) and (b). As with the above embodiment, the windowed panel according to this modified example comprises a panel body 101 and a window member 102 that is assembled to an opening of the panel body 101. In the windowed panel described after this modified example, the parts other than the assembly structure of the window member to the panel body are the same as those in the above embodiment, so detailed explanations will be omitted.

[0057] 7(a) and (b), the panel body 101 is configured by holding the outer peripheries of a front panel 111f and a rear panel 111r, which are rectangular panel members, on the front and rear sides of a frame member. A front opening is formed in the front panel 111f of the panel body 101, and a rear opening is formed in the rear panel 111r. A front inner frame 112f and a rear inner frame 112r are provided between the front panel 111f and the rear panel 111r adjacent to the openings. A connected portion 112a that supports the window member 102 is formed in the front inner frame 112f.

[0058] 7(a) and (b), the window member 102 according to this modification is configured by providing a front window plate 122f, which is a window plate on one side, and a rear window plate 22r, which is a window plate on the other side, in a window frame 121. Specifically, the four sides of the front window plate 122f, which is a rectangular glass plate, are held by the front side of the four frame members that constitute the window frame 121. Similarly, the four sides of the rear window plate 122r are held by the rear side of the four frame members that constitute the window frame 121. Then, the ends of the respective frame members are connected by an L-shaped plate 125 to form the window member 102 in which the front window plate 122f is held by the front end of the rectangular window frame 121 and the rear window plate 122r is held by the rear end.

[0059] As shown in Fig. 7(a), the rear portion of the window member 102 is inserted from the front side of the panel body 101 into a front opening formed in a front panel 111f, and assembled to the panel body 101. As shown in Fig. 7(a), a connecting recess 121a is formed around the front window plate 122f on the front surface of the window frame 121 in the window member 102. Then, as shown in Fig. 7(a), when the window member 102 is assembled to the panel body 101, the rear surface of the connecting recess 121a and the connected portion 112a come close to each other.

[0060] In this state, a fixing screw 124, which is a fastening member, is inserted into the connecting recess 121a, and the fixing screw 124 is screwed into the bottom surface of the connecting recess 121a and the connected portion 112a. As a result, the window member 102 is fastened to the panel body 101. In this modified example, as shown in Figure 7 (b), a cover member 123 is inserted into the front opening of the connecting recess 121a. As a result, the fixing screw 124 is covered by the cover member 123.

[0061] As described above, in the window panel according to this modified example, the window member 102 is fastened with the fixing screws 124, thereby restricting its position in the opening of the panel body 101 so as not to fall off. In this way, the window member 102 can be easily attached to the opening of the panel body 101, and therefore the window plates 122f, 122r can also be easily attached and detached in the window panel according to this modified example.

[0062] Furthermore, in the window panel according to this modified example, the window member 102 is integrally constructed by holding the two window plates 122f and 122r with one window frame 121. This makes it possible to integrally assemble the window member 102 from the front side to the opening of the panel body 101, thereby further improving the ease of assembly of the window member 102. That is, in the window panel according to this modified example, the window plates 122f and 122r can be more easily attached and detached.

[0063] [Second modified example] Next, a windowed panel according to a second modified example of the present invention will be described with reference to Figures 8(a) and (b). The windowed panel according to this modified example comprises a panel body 201 and a window member 202 that is attached to an opening of the panel body 201, as in the above embodiment.

[0064] 8(a) and (b), the panel body 201 is configured by holding the outer periphery of a front panel 211f and a rear panel 211r, which are rectangular panel members, on the front and rear sides of a frame member. A front opening is formed in the front panel 211f of the panel body 201, and a rear opening is formed in the rear panel 211r. An inner frame 212 adjacent to the opening is provided between the front panel 211f and the rear panel 211r.

[0065] 8(a) and 8(b), the window member 202 according to this modification is configured by combining a front window member which is a one-side window member and a rear window member which is the other-side window member. The front window member is configured by providing a front window plate 222f which is a one-side window plate on a front window frame 221f which is a one-side window frame.

[0066] Specifically, the four sides of the front window plate 222f, which is a rectangular glass plate, are held by four frame members constituting the front window frame 221f. The ends of the respective frame members are connected by L-shaped plates 225 to form a front window member in which the front window plate 222f is held by the front end of the rectangular front window frame 221f.

[0067] Similarly to the front window member, the rear window member is configured by providing a rear window plate 222r, which is the other side window plate, to a rear window frame 221r, which is the other side window frame. Specifically, the four sides of the rear window plate 222r, which is a glass plate having the same shape as the front window plate 222f, are held by four frame members that constitute the rear window frame 221r. The ends of each frame member are connected by L-shaped plates 225 to form a rear window member in which the rear window plate 222r is held by the rear end of the rectangular rear window frame 221r.

[0068] 8(a), the rear part of the front window member is inserted from the front side of the panel body 201 into a front opening opened in the front panel 211f and assembled to the panel body 201. Similarly, the front part of the rear window member is inserted from the rear side of the panel body 201 into a rear opening opened in the rear panel 211r and assembled to the panel body 201.

[0069] As shown in Fig. 8(b), a connecting recess 221b is formed around the front window plate 222f on the front surface of the front window frame 221f of the front window member. Also, a connected portion 221c is formed on the front end portion of the rear window member. Then, as shown in Fig. 8(b), when the front window member and the rear window member are assembled to the panel body 201, the rear part of the front window member is inserted inside the front part of the rear window member, and the rear surface of the connecting recess 221b and the front surface of the connected portion 221c are brought into close proximity.

[0070] In this state, a fixing screw 224, which is a fastening member, is inserted into the connecting recess 221b, and the fixing screw 224 is screwed into the bottom surface of the connecting recess 221b and the connected portion 221c. As a result, the front window member and the rear window member are fastened to each other on the front side of the panel body 201. In this modified example, as shown in Figure 8 (b), a cover member 223 is inserted into the front opening of the connecting recess 221b. As a result, the fixing screw 224 is covered by the cover member 223.

[0071] As described above, in the window panel according to this modified example, the front window member and the rear window member are fastened with the fixing screw 224, and thus their positions are restricted so that they cannot be displaced in the direction away from each other (front-rear direction). In other words, the window member 202 is restricted in position relative to the opening of the panel body 201 so that it cannot fall off.

[0072] As described above, in the window panel according to this modified example, the window member 202, which includes a window frame (front window frame 221f and rear window frame 221r) and window plates (front window plate 222f and rear window plate 222r), is assembled to an opening in the panel body 201 using fastening members, namely fixing screws 224. In this way, the window member 202 can be easily assembled to the opening in the panel body 201, and therefore it is possible to easily attach / detach the window plates 222f-222r in the window panel.

[0073] 8(b), the windowed panel according to this modification has an inclined inner peripheral surface 221e located in front of the rear window plate 222r in the rear window frame 221r. This allows the user of the windowed panel to view the window member 202 and recognize that the inner peripheral surface 221d located in the front window frame 221f behind the front window plate 222f and the inner peripheral surface 221e are continuous. In other words, this modification makes it possible to improve the design of the windowed panel.

[0074] [Third Modification] 9(a) and (b), a windowed panel according to a third modified example of the present invention will be described. The windowed panel according to this modified example comprises a panel body 301 and a window member 302 that is attached to an opening of the panel body 301, as in the above embodiment.

[0075] 9(a) and (b), the panel body 301 is configured by holding the outer periphery of a front panel 311f and a rear panel 311r, which are rectangular panel members, on the front and rear sides of a frame member. A front opening is formed in the front panel 311f of the panel body 301, and a rear opening is formed in the rear panel 311r. An inner frame 312 is provided between the front panel 311f and the rear panel 311r, adjacent to the openings.

[0076] 9(a) and (b), the window member 302 according to this modification is configured by combining a front window member which is a one-side window member and a rear window member which is the other-side window member. The front window member is configured by providing a front window plate 322f which is a one-side window plate on a front window frame 321f which is a one-side window frame.

[0077] Specifically, the four sides of the front window plate 322f, which is a rectangular glass plate, are held by four frame members that constitute the front window frame 321f. The ends of the respective frame members are connected by L-shaped plates (not shown) to form a front window member in which the front window plate 322f is held by the rear end of the rectangular front window frame 321f.

[0078] The rear window member is also configured in the same manner as the front window member, by providing a rear window plate 322r, which is the other side window plate, on a rear window frame 321r, which is the other side window frame. Specifically, the four sides of the rear window plate 322r, which is a glass plate having the same shape as the front window plate 322f, are held by the four frame members that constitute the rear window frame 321r. The ends of each frame member are connected by an L-shaped plate 325 to form a rear window member in which the rear window plate 322r is held at the rear end of the rectangular rear window frame 321r. As shown in FIG. 9(a), the L-shaped plate 325 is fixed to the frame member of the rear window frame 321r in a state where it is inserted into an insertion hole 321a formed in the rear window frame 321r.

[0079] 9(a), the rear part of the front window member is inserted from the front side of the panel body 301 into a front opening opened in a front panel 311f, and assembled to the panel body 301. Similarly, the front part of the rear window member is inserted from the rear side of the panel body 301 into a rear opening opened in a rear panel 311r, and assembled to the panel body 301.

[0080] As shown in FIG. 9(b), a connecting portion 321b is formed in front of the front window plate 322f in the front window frame 321f of the front window member. A connected portion 321c is formed at the front end of the rear window member. Then, as shown in FIG. 9(b), when the front window member and the rear window member are assembled to the panel body 301, the rear portion of the front window member is inserted inside the front portion of the rear window member, and the outer surface of the connecting portion 321b and the inner surface of the connected portion 321c are brought into close proximity. In this state, a fixing screw 324, which is a fastening member, is screwed into the connecting portion 321b and the connected portion 321c from the inner surface side of the connecting portion 321b. As a result, the front window member and the rear window member are fastened to each other on the front side of the panel body 301.

[0081] As described above, in the window panel according to this modified example, the front window member and the rear window member are fastened with the fixing screw 324, and thus their positions are restricted so that they cannot be displaced in the direction away from each other (front-rear direction). In other words, the window member 302 is restricted in position relative to the opening of the panel body 301 so that it cannot fall off.

[0082] As described above, in the window panel according to this modified example, the window member 302, which includes a window frame (front window frame 321f and rear window frame 321r) and window plates (front window plate 322f and rear window plate 322r), is assembled to an opening in the panel body 301 using fastening members, namely fixing screws 324. In this way, the window member 302 can be easily assembled to the opening in the panel body 301, making it possible to easily attach / detach the window plates 322f-322r in the window panel.

[0083] Furthermore, in the windowed panel according to this modified example, the fixing screws 324 are configured to be screwed in from the inner surface side of the connecting portion 321b. This makes it possible to make the fixing screws 324 less visible when the window member 302 is viewed from the front. That is, in this modified example, there is no need to provide a cover member to cover the fixing screws 324, making it possible to reduce the number of parts.

[0084] [Fourth modified example] Next, a windowed panel according to a fourth modified example of the present invention will be described with reference to Figures 10 to 12. The windowed panel according to this modified example comprises a panel body 401 and a window member 402 that is attached to an opening of the panel body 401, similar to the above embodiment.

[0085] 10(a) and (b), the panel body 401 is configured by holding the outer periphery of a front panel 411f and a rear panel 411r, which are rectangular panel members, on the front and rear sides of a frame member. A front opening is formed in the front panel 411f of the panel body 401, and a rear opening is formed in the rear panel 411r.

[0086] An inner frame 412 is provided adjacent to the side of the opening between the front panel 411f and the rear panel 411r of the panel body 401. A latched portion 412a that protrudes toward the opening is formed on each of the front and rear sides of the inner frame 412. As shown in Fig. 11, the latched portion 412a is formed in a hook shape that faces upward.

[0087] 12, adjacent and above the opening, a fixing frame 413 is provided between the front panel 411f and the rear panel 411r of the panel body 401. Fixed portions 413a extend toward the opening on both the front and rear sides of the fixing frame 413.

[0088] 10(a) and 10(b), the window member 402 according to this modification is composed of a front window member which is a one-side window member and a rear window member which is the other-side window member. The front window member is composed of a front window frame 421f which is a one-side window frame and a front window plate 422f which is a one-side window plate provided on the front window frame 421f which is a one-side window frame.

[0089] Specifically, the four sides of the front window plate 422f, which is a rectangular glass plate, are held by four frame members constituting the front window frame 421f. The ends of the respective frame members are connected by L-shaped plates 425 to form a front window member in which the front window plate 422f is held by the front end of the rectangular front window frame 421f.

[0090] Like the front window member, the rear window member is configured by providing a rear window plate 422r, which is a window plate on the other side, to a rear window frame 421r, which is a window frame on the other side. Specifically, the four sides of the rear window plate 422r, which is a glass plate having the same shape as the front window plate 422f, are held by four frame members that constitute the rear window frame 421r. The ends of each frame member are connected by an L-shaped plate 425 to form a rear window member in which the rear window plate 422r is held by the rear end of the rectangular rear window frame 421r.

[0091] As shown in Figs. 10(a) and (b), a locking portion 421a protruding toward the rear is formed on the side of the front window frame 421f. Similarly, a locking portion 421a protruding toward the front is formed on the side of the rear window frame 421r. That is, the locking portions 421a are formed on the two opposing left and right sides around the periphery of the window member 402 according to this modification. As shown in Fig. 11, the locking portions 421a are formed with a hook shape facing downward. Each locking portion 421a is configured to be able to be locked in correspondence with a locked portion 412a formed on the inner frame 412.

[0092] 10(a) and (b), the rear part of the front window member is inserted from the front side of the panel body 401 into the front opening formed in the front panel 411f, and the locking part 421a is locked to the locked part 412a. This allows the front window member to be assembled to the front opening of the panel body 401.

[0093] 10(a), (b) and 11, the front part of the rear window member is inserted from the rear side of the panel body 401 into the rear opening opened in the rear panel 411r, and the locking part 421a is locked to the locked part 412a. This allows the rear window member to be assembled to the rear opening of the panel body 401.

[0094] As described above, in the window panel according to this modified example, the front window member including the front window frame 421f and the front window plate 422f is assembled to the opening of the panel body 401 by engaging the engaging portion 421a with the engaging portion 412a. Similarly, the rear window member including the rear window frame 421r and the rear window plate 422r is assembled to the opening of the panel body 401 by engaging the engaging portion 421a with the engaging portion 412a. In this way, the window member 402 can be easily assembled to the opening of the panel body 401, and therefore the window plates 422f and 422r can be easily attached and detached in the window panel.

[0095] In this modification, the front window frame 421f and the rear window frame 421r are dropped downward when the front window member and the rear window member are attached to the panel body 401. Therefore, as shown in Fig. 12, gaps are formed between the upper end surface of the front window frame 421f and the upper side of the front opening formed in the front panel 411f, and between the upper end surface of the rear window frame 421r and the upper side of the rear opening formed in the rear panel 411r.

[0096] In this modification, the front window member and the rear window member are configured to include a plate-shaped restricting member 423. The restricting member 423 is interposed between the upper end faces of the front window frame 421f and the rear window frame 421r and the upper sides of the openings formed in the front panel 411f and the rear panel 411r. In this state, fixing screws 424, which are fastening members, are screwed into the restricting members 423 and the fixed parts 413a formed on the fixing frame 413. As a result, the front window member and the rear window member are fixed to the panel body 401.

[0097] In this modification, as in the window member 402A shown in Fig. 13, it is possible to form the restricting portion 432 in the front window frame 431f of the front window member. That is, it is possible to use the front window frame 431f in Fig. 12, in which the front window frame 421f and the restricting member 423 are integrally formed. Similarly, in Fig. 13, the restricting portion 432 is formed in the rear window frame 431r of the rear window member.

[0098] In this case, fixing screws 424, which are fastening members, are screwed into the restricting portions 432 and the fixed portions 413a formed on the fixed frame 413. This causes the front window member and the rear window member to be fixed to the panel body 401.

[0099] As described above, in the window panel according to this modified example, the front and rear window members are fastened with fixing screws 424, and their positions are restricted so that they cannot be displaced in directions away from each other (front-to-rear directions) or upward. That is, the window member 402 is restricted in position relative to the opening of the panel body 401 so that it cannot fall off. In this way, with the window panel according to this modified example, by restricting displacement of the front and rear window members with restricting members 423 (restricting portions 432) and fixing screws 424, it is possible to stably assemble the window member 402 (window member 402A) to the panel body 401.

[0100] [Other variations] The above-described embodiment and modified examples can be modified as appropriate as shown in the other modified examples below. Note that each modified example described in this specification may be applied in combination with other modified examples to the extent that no contradiction occurs.

[0101] The window panel of the present invention can be used not only as the door body of a door structure as in this embodiment, but also widely as a panel component to which a window panel is attached, such as a partition panel that constitutes a building fixture.

[0102] Furthermore, the position, shape, number, etc. of the window members in the windowed panel can be appropriately changed from the position, shape, number, etc. in this embodiment. For example, the window member can be arranged in the center of the windowed panel, can be circular, or can be provided in two or more units.

[0103] It is also possible for the front-to-rear positions of the surface of the panel body and the surface of the window plate to be different on one or the other of the front and rear faces of the window panel (the step formed by the surface of the panel body and the surface of the window plate can be 3 mm or more).

[0104] The window pane in the window panel may be provided on either one side or the other side of the window frame. For example, a window pane may be provided on only one side of the window member, and a steel plate may be provided on the other side. Also, like the window panel according to the first modified example, two window panes may be held by one window frame, and the window member may be constructed as an integrated unit.

[0105] In addition, in a window panel, a double structure in which window plates are provided on both one side and the other side of the window frame is preferable because this ensures high sound insulation and design properties in the window member. Furthermore, the window panel according to the present invention is preferable because, even when the window plate has a double structure, the window member in the window panel can be easily attached / detached compared to conventional techniques.

[0106] Furthermore, as the window plate in the window panel, in addition to transparent plates such as glass plates and acrylic plates, it is also possible to use transparent plates with a design sheet attached, plate materials with translucency such as haze glass, etc. In this case, the window plate in the window panel is suitable for use if it has a translucency that allows the user to visually check the use status of the room, such as whether the lights are on in the space (room) on the opposite side of the window panel and whether there are people in the room.

[0107] It is also possible to configure the window panel so that the front and rear window members are fastened to each other on the rear side of the panel body by fastening members. That is, when assembling the window member to the panel body, the worker can fasten the front and rear window members to the front or rear side of the window panel, whichever is easier for the worker to work on.

[0108] Furthermore, except for the window panel according to the first modified example, the window member can be attached to the panel body even if it is reversed front to back. This makes it possible to configure the window panel by selecting the design that appears on the front and back when the front and rear designs of the window member are different. When the window panel is used as the door body as in this embodiment, it is possible to select the design of the window panel that appears on the inside or outside of the room and attach it to the door structure.

[0109] It is also possible to configure the window panel without providing a cover member that covers the fastening member.It is also possible to configure the window panel without providing a sound insulation material inside the panel body.On the other hand, even if a sound insulation material is provided, it is also possible to adopt other materials as the sound insulation material, such as rock wool, gypsum board, porous sound absorbing board, felt material, wood wool board, etc., in addition to glass wool and airtight material.
