Arrange the L-shaped member 53 at a height where the protruding piece 532 of the L-shaped member 53 can be fixed to the bottom of the frame hole portion 251. Fix the fixing piece 531 of the upper frame fixing member 52 to the sleeve panel 4. Fix the protruding piece 532 to the bottom of the frame hole portion 251. Attach the cover member 54 to the first end face 41 so as to cover the lower side of the L-shaped member 53. In this way, the sleeve panel 4 is fixed to the frame portion 21, and the door 1 with a sleeve panel is installed on the frame portion 21 of the existing double door 2.

[0040] Since the furniture structure and the furniture renovation method according to the above embodiment have a configuration in which the sleeve panel 4 is fixed to the frame portion 21 by the first sleeve panel fixing portion 5 and the second sleeve panel fixing portion 6, the door body 32 and the sleeve panel 4 of the door 1 with a sleeve panel can be installed on the frame portion 21 of the existing double door 2. That is, the double door 2 can be renovated into the door 1 with a sleeve panel by renovation or the like. Various functional members such as lighting and storage can be attached to the sleeve panel 4. Various functions such as lighting, an electronic lock, an entrance and exit authentication device, and storage can be added to the sleeve panel 4. Therefore, the functionality of the entrance space provided with the sleeve panel 4 can be improved. Since handles, latches, keys, etc. can also be attached to the sleeve panel 4, the range of selection of handles and keys attached to the door 1 with a sleeve panel can be widened.

[0041] In the fitting structure according to the above-described embodiment, the lower frame 24 and the upper frame 25 are provided with receiving fittings 242 and 252 in which frame holes 241 and 251 into which the rods for French drop provided on the sub-door 23 are inserted are formed, respectively. The door 1 with a sleeve panel has a first sleeve panel fixing portion 5 that is inserted into the frame holes 241 and 251 and is attached to the sleeve panel 4. With such a configuration, the sleeve panel 4 can be easily and surely fixed to the frame portion 21 by using the frame holes 241 and 251 of the lower frame 24 and the upper frame 25.

[0042] In the fitting structure according to the above-described embodiment, the second sleeve panel fixing portion 6 has a frame-side fixing portion 61 attached to the second vertical frame 27 and a sleeve-side fixing portion 62 provided on the second end face 42 of the sleeve panel 4 and fixed to the frame-side fixing portion 61. With such a configuration, the sleeve panel 4 can be easily fixed to the frame portion 21.

[0043] The present disclosure is not limited to the above-described embodiment and can be appropriately changed. For example, the form of the sleeve panel fixing portion for fixing the sleeve panel 4 to the lower frame 24 and the upper frame 25 may be other than the above.

[0044] In the above-described embodiment, the door 1 with a sleeve panel has a second sleeve panel fixing portion 6 in which a frame-side fixing portion 61 attached to the second vertical frame 27 and a sleeve-side fixing portion 62 provided on the second end face 42 of the sleeve panel 4 and fixed to the frame-side fixing portion 61 are fitted together. The second sleeve panel fixing portion 6 fixes the sleeve panel 4 to the second vertical frame 27. The form of the sleeve panel fixing portion for fixing the sleeve panel 4 to the second vertical frame 27 may be other than the above.

[0045] In the above-described embodiment, the sleeve panel 4 is provided with an authentication device 43 for entry and exit, and cylinders 44 and 45, and various functions such as lighting, an electronic lock, and storage can be added. The members provided on the sleeve panel 4 and the functions that can be added may be other than the above. The sleeve panel 4 does not necessarily have to have the functions as described above.

[0046] In the above embodiment, a latch for a handle is provided on the door body 32, and a latch receiver is provided on the sleeve panel 4. In contrast, the door 1 with a sleeve panel can also be configured without a latch. Since a general latch is interlocked with the opening and closing operation of the handle, if a latch is provided on the door body 32, the position of the handle is automatically determined. On the other hand, a latch called a free latch is not interlocked with the opening and closing operation of the handle. A free latch may be provided on either the door body 32 or the sleeve panel 4. By doing so, the position of the handle can be freely selected, and the design property of the door 1 with a sleeve panel can be improved.

[0047] In the above embodiment, the sleeve-side fixing portion 62 of the second sleeve panel fixing portion 6 has the first sleeve-side fixing portion 7 and a plurality of second sleeve-side fixing portions 8. The sleeve-side fixing portion 62 may be composed of one member.
