Abstract

PURPOSE:To facilitate opening and shutting of a lid plate and prevent damage due to interference of components one another by joining the lid plate with a link pivoted on a ceiling, and equipping the ceiling with a guide piece to guide motions of the lid plate in the direction of link rotation. CONSTITUTION:When an inspection lid 4 is to be opened by an opening/shutting mechanism for lid plate of an elevator cage, removing a set screw 6 causes opening of the inspection lid 4 in rotating round a shaft 15 and also allows a link 14 to turn round a shaft 12, so that the former named shaft 15 will move to right under the latter named shaft 12. Therefore, the front end of the inspection lid 4 rotates downward, and the opening 3a is opened wide. To shut the inspection lid, the procedure shall be followed oppositely, when the link 14 turns counterclockwise and the inspection lid 4 blocks the opening 3a and is secured by the set screw 6. With rotation of the link 14 the inspection lid 4 swings to the right, with the motions are restricted by a guide piece 16, which allows the inspection lid 4 or an illuminating device 5 to avoid colliding with a suspension ceiling 3, and they are prevented from damages.

Description

[Detailed description of the invention]

FIELD OF INDUSTRIAL APPLICATION This invention relates to a mechanism for opening and closing a cover plate for closing a rescue door and a lighting inspection port provided in the ceiling of an elevator car. [0002] [0002] FIGS. 4 to 8 are diagrams showing a conventional elevator car compartment cover opening/closing mechanism, in which FIG. 4 is a longitudinal sectional view of the cage, and FIG. 5 is a view taken along the V-V plane in FIG. 4. 6 is an enlarged view of the main part of FIG. 4, FIG. 7 is a bottom view of FIG. 6, and FIG. 8 is an explanatory view of attaching and detaching the inspection lid. [0003] In the figure, (1) is a side wall forming the periphery of the car compartment, (2) is a canopy fixed to the upper edge of side wall (1), and (
3) is a suspended ceiling that forms a void below the canopy (2),
It has a circular opening (3a) in the center. (4) is an inspection lid that closes the opening (3a), (5) is a lighting body arranged on the inspection lid (4), and (6) is a stopper that holds the inspection lid (4) to the suspended ceiling (3). The screw (7) is a chain that connects the inspection lid (4) and the canopy (2). Although not shown, the chain (7) has a length sufficient to lower the inspection lid (4). It is assumed that there is (8) is a lighting lamp attached to the canopy (2). [0004] The conventional elevator car door opening/closing mechanism is constructed as described above, and when opening the inspection lid (4), the set screw (6) is removed and the inspection lid (4) is supported by hand. When lowered, the opening (3a) is opened. The inspection lid (4) is supported by the canopy (2) in a state where the chain (7) has finished extending as shown in FIG. This makes it possible to inspect the space between the canopy (2) and the suspended ceiling (3). [0005]

[Problems to be Solved by the Invention] In the conventional elevator-car lid opening/closing mechanism as described above, the inspection lid (4)
Since the inspection lid (4) is lowered and supported by the chain (7), there is a problem in that the inspection lid (4) is heavy and requires two workers to remove and install it. Also, when the inspection lid (4) is lowered, the inspection lid (4)
) cannot be fixed, and the suspended ceiling (3) and inspection lid (4) may come into contact and cause damage. [0006] This invention was made to solve the above-mentioned problems, and provides a lid opening/closing mechanism for an elevator car that allows the lid to be easily opened and closed and prevents damage due to mutual interference between parts. The purpose is to provide [0007]

[Means for Solving the Problems] A lid plate opening/closing mechanism for an elevator car according to the present invention connects a lid plate to a link pivotally attached to a ceiling part, and connects the lid plate to the ceiling part in the direction of rotation of the link. A guide piece is provided to restrict the movement of the plate. [0008]

[Operation] In the present invention, since the cover plate is connected to the ceiling through the link, the force required to open and close the cover plate is reduced. Further, since a guide piece is provided to restrict movement of the cover plate in the direction of rotation of the link, movement of the cover plate is restricted. [0009]

[Embodiment] Figures 1 to 3 are views showing one embodiment of the present invention, in which Figure 1 is a vertical sectional view of the main part, Figure 2 is a bottom view of Figure 1, and Figure 3 is a diagram for explaining the attachment and detachment of the inspection lid. , parts similar to those of the conventional device are designated by the same reference numerals. Note that FIGS. 4 and 5 are also used in this embodiment. (00101 In the figure, (11) is a support metal fixed to the suspended ceiling (3) and placed near the inner edge of the opening (3a);
2) is a shaft whose both ends are pivotally supported by supports (11); (13);
is the support provided on the inspection lid (4), and (14) is the shaft (
12), and is pivotally supported by a support (13) by a shaft (15) at its tip. (16) is a guide piece fastened near the inner edge of the opening (3a) of the suspended ceiling (3) and protruding into the opening (3a). [00111 In the elevator car compartment lid opening/closing mechanism configured as described above, when opening the inspection lid (4), remove the setscrew (6) and the inspection lid (4) can be opened with the shaft (
15), and the link (14) opens around the axis (
12), so as shown in Figure 3,
The shaft (15) moves directly below the shaft (12). Now, the front end (left end in the figure) of the inspection lid (4) will rotate downward,
The opening (3a) is wide open. (0012) When closing the inspection lid (4), the operation is the reverse of the above, the link (14) rotates counterclockwise, and the inspection lid (4) closes the opening (3a) and stops. It is fixed with a screw (6).The rotation of the link (14) causes the inspection lid (4) to swing to the right, but its movement is restricted by the guide piece (16), and the inspection lid (4) Or lighting body (5
) is avoided from colliding with the suspended ceiling (3), and damage to both can be prevented. [00133 Since the inspection lid (4) is connected via the link (14), the force required to open and close the inspection lid (4) can be reduced to approximately 1/2 compared to the conventional one, requiring only one operator. You can work with [0014] In the above embodiment, the inspection lid (4) has been described, but it is also applicable to a mechanism for opening and closing a lid that closes a rescue opening (not shown) provided in the canopy (2). [0015]

[Effects of the Invention] As explained above, in this invention, the lid plate is connected to a link pivotally mounted on the ceiling, and a guide piece is provided on the ceiling to restrict the movement of the lid plate in the direction of rotation of the link. Therefore, the force required to open and close the lid plate is reduced, and the lid plate can be opened and closed easily. Furthermore, the movement of the cover plate is restricted, which has the effect of preventing damage due to mutual interference between parts.
