Abstract

The present invention provides an openable extended panel, and a lift ceiling, lift car and lift system having same, wherein the openable extended panel is mounted to a support frame and is in positional correspondence to an escape exit at a car roof; the openable extended panel is rotatably connected to the support frame at a first side, and the openable extended panel is connected to the support frame via an intermediate member at a second side opposite to the first side, the support frame and the openable extended panel being respectively detachably connected to the intermediate member. The openable extended panel according to the embodiments of the present invention has a simple structure, and can be easily opened.

First claim

What is claimed is:

1. A lift ceiling arranged below a car roof, comprising:
a support frame and a plurality of extended panels mounted to the support frame;
wherein the plurality of extended panels comprise an openable extended panel, and the openable extended panel is aligned with an escape exit of the car roof;
wherein the openable extended panel is rotatably connected to the support frame at a first side, and the openable extended panel is connected to the support frame via an intermediate member at a second side opposite to the first side;
wherein the support frame and the openable extended panel are respectively detachably connected to the intermediate member;
wherein the openable extended panel is also provided with an anti-falling mechanism for preventing the openable extended panel from falling down accidentally;
wherein the anti-falling mechanism comprises: a guiding slot provided on one of the openable extended panel and an extended panel adjacent to the openable extended panel, and a laterally extending part provided on the other one of same, the laterally extending part is aligned to a notch or stop part of the guiding slot by means of the translation of the openable extended panel, so as to allow or restrict the rotation of the openable extended panel.

2. The lift ceiling according to claim 1 , wherein the plurality of extended panels also comprise a fixed decorative panel and/or a light source panel.

3. The lift ceiling according to claim 2 , wherein the light source panel comprises a point light source or an area light source.

4. The lift ceiling according to claim 1 , wherein the support frame is composed of a plurality of struts, and defines a plurality of rectangular mounting openings, and all of the plurality of extended panels are formed in a rectangular shape and are mounted on the corresponding mounting openings.

5. The lift ceiling according to claim 4 , wherein the plurality of extended panels comprise:
a first panel longitudinally extending along the entire lift ceiling at a first side of the lift ceiling;
a second panel longitudinally extending along the entire lift ceiling at a second side of the lift ceiling; and
at least one intermediate panel laterally extending between the first panel and the second panel.

6. The lift ceiling according to claim 5 , wherein the at least one intermediate panel comprises two or three laterally extending intermediate panels.

7. The lift ceiling according to claim 5 , wherein the first panel and the second panel are light source panels, and one of the intermediate panels constitutes the openable extended panel.

8. The lift ceiling according to claim 1 , wherein the openable extended panel and the intermediate member are connected via a first connection piece, the first connection piece being able to be accessed and disassembled from inside an elevator car, and the support frame and the intermediate member are connected via a second connection piece, the second connection piece being able to be accessed and disassembled from an elevator car roof.

9. The lift ceiling according to claim 8 , wherein the intermediate member is a bent plate, and the bent plate has a first connecting face and a second connecting face perpendicular to each other, wherein the first connecting face of the bent plate is connected to the first connection piece passing through the openable extended panel, and the second connecting face of the bent plate is connected to the support frame via the second connection piece.

10. The lift ceiling according to claim 8 , wherein the first connection piece is a locking bolt, the locking bolt comprising a head that can be accessed from the lift car side and a tail end that passes through the openable extended panel; and the second connection piece is a butterfly bolt.

11. The lift ceiling according to claim 1 , wherein the openable extended panel can be translated, so that the openable extended panel switches between an interfered location where the anti-falling mechanism functions and a released location where the openable extended panel is allowed to be opened.

12. A lift car, wherein the lift car comprises the lift ceiling as claimed in claim 1 .

13. A lift system, wherein the lift system comprises a lift car, and the lift car comprises the lift ceiling as claimed in claim 1 .

14. An openable extended panel for a lift ceiling, mounted to a support frame and aligned with an escape exit of a car roof;
wherein the openable extended panel is rotatably connected to the support frame at a first side, and the openable extended panel is connected to the support frame via an intermediate member at a second side opposite to the first side;
wherein the support frame and the openable extended panel are respectively detachably connected to the intermediate member;
wherein the intermediate member is a bent plate, and the bent plate has a first connecting face and a second connecting face perpendicular to each other, wherein the first connecting face of the bent plate is connected to the first connection piece passing through the openable extended panel, and the second connecting face of the bent plate is connected to the support frame via the second connection piece.

15. The openable extended panel according to claim 14 , wherein the openable extended panel is formed into a rectangle.

16. The openable extended panel according to claim 14 , wherein the openable extended panel and the intermediate member are connected via a first connection piece, the first connection piece being able to be accessed and disassembled from inside an elevator car, and the support frame and the intermediate member are connected via a second connection piece, the second connection piece being able to be accessed and disassembled from an elevator car roof.

17. The openable extended panel according to claim 16 , wherein the first connection piece is a locking bolt, the locking bolt comprising a head that can be accessed from the lift car side and a tail end that passes through the openable extended panel; and the second connection piece is a butterfly bolt.

18. The openable extended panel according to claim 14 , wherein the openable extended panel is also provided with an anti-falling mechanism for preventing the openable extended panel from falling down accidentally.

19. The openable extended panel according to claim 18 , wherein the openable extended panel can be translated, so that the openable extended panel switches between an interfered location where the anti-falling mechanism functions and a released location where the openable extended panel is allowed to be opened.

20. The openable extended panel according to claim 18 , wherein the anti-falling mechanism comprises: a guiding slot provided on one of the openable extended panel and an extended panel adjacent to the openable extended panel, and a laterally extending part provided on the other one of same, the laterally extending part is aligned to a notch or stop part of the guiding slot by means of the translation of the openable extended panel, so as to allow or restrict the rotation of the openable extended panel.
