Description

  The present invention relates to a car ceiling structure for an elevator that prevents floating of a shielding plate provided on the car ceiling and horizontal displacement.

In the elevator car ceiling structure where a joint frame is provided around the ceiling of the car and a shielding plate is mounted in the joint frame, in order to prevent the shielding plate from rising and horizontally shifting, A locking means having an inclined side, that is, a strip plate is attached to each of the four sides, and the strip plate elastically supports the shielding plate (for example, see Patent Document 1).
JP-A-2-255485 (second page, lower right column to page 3, upper left column, FIGS. 1 and 2)

  However, in the above-described car ceiling structure, there is a problem that it is necessary to provide locking means on each of the four sides of the shielding plate, which requires a large number of parts. In addition, since there are locking means on the four sides of the shielding plate, the gap between the remaining locking means and the shielding plate becomes smaller as the shielding plate is sequentially locked by the locking means, and the shielding plate can be attached. There was also a problem that it became difficult to get used to the work.

  The present invention has been made from the above-described state of the art, and the object thereof is to prevent the shield plate from being lifted and displaced in the horizontal direction with a relatively small number of components, and to easily attach the shield plate. It is to provide an elevator car ceiling structure that can.

  In order to achieve the above object, an invention according to claim 1 of the present invention provides a joint frame provided around a car ceiling, a shielding plate attached to the joint frame, the floating of the shielding plate, and a horizontal direction. In an elevator car ceiling structure provided with locking means for preventing slippage, the locking means are arranged as a pair in two opposite directions of the shielding plate, and these locking means are the shielding plate. It is characterized by comprising a notch formed continuously on the rising side and the horizontal side of the end, and a loosely fitted body provided in the joint frame and loosely fitted in the notch.

  In the invention according to claim 1 of the present invention configured as described above, when the shielding plate is attached to the car ceiling, the loose fitting provided on the joint frame is formed on the rising side and the horizontal side of the shielding plate end. It fits loosely in the notch. Accordingly, the horizontal movement of the shielding plate, that is, the movement in the frontage direction and the depth direction, is suppressed by the loosely fitting body contacting the shielding plate or the loosely fitting body contacting the notch end. At the same time, the vertical movement of the shielding plate is suppressed by the loosely fitting body coming into contact with the upper surface of the shielding plate. Therefore, the shield plate can be prevented from being lifted and displaced in the frontage direction and the depth direction by a pair of locking means arranged in two opposite directions of the shield plate, and the number of parts can be reduced as compared with the conventional case. be able to. In addition, since the locking means is installed only in two directions of the shielding plate and the loosely fitting body is loosely fitted into the notch at the end of the shielding plate, the shielding plate can be easily attached to the ceiling of the car. it can.

  In the invention according to claim 2 of the present invention, the loosely fitting body has a substantially L-shaped cross-sectional shape, and a vertical side of the loosely fitted body is attached to the joint frame and a horizontal side of the bracket. It consists of a bolt and a nut.

  In the invention according to claim 2 of the present invention configured as described above, the movement in the frontage direction of the shielding plate is suppressed when one of the bolt and the nut contacts the shielding plate, and the movement in the depth direction is performed by the bracket. The movement of the shielding plate in the vertical direction is suppressed by contacting the notch end, and the bracket is suppressed by contacting the upper surface of the shielding plate. As described above, the loosely fitting body can be configured with a simple structure such as a bracket having a substantially L-shaped cross-sectional shape, and a bolt and a nut attached to the bracket.

  According to the present invention, it is possible to prevent the shielding plate from being lifted by the pair of locking means, and to prevent the gap direction and the depth direction from being shifted, thereby reducing the number of parts compared to the conventional case and thus reducing the cost. Can be planned. In addition, since the locking means is installed only in two directions of the shielding plate and the loosely fitting body is loosely fitted in the notch at the end of the shielding plate, the shielding plate can be easily attached to the car ceiling. it can.

  Embodiments of an elevator car ceiling structure according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of an elevator car to which a car ceiling structure according to the present invention is applied, FIG. 2 is a longitudinal sectional view of a car ceiling part, and FIG. 3 shows an embodiment of an elevator car ceiling structure according to the present invention. FIG. 4 is a perspective view showing the main part of the shielding plate, and FIG. 5 is a perspective view showing the main part of the loosely fitting body.

  As shown in FIG. 1, the elevator car 1 has a plurality of side plates 2 and a car ceiling 3 that is attached to the top of these side plates 2. And a joint frame 4 having a substantially L-shaped cross-section and a shielding plate 5 attached to the horizontal side 4a of the joint frame 4 and having an end portion bent into a substantially L-shape. ing.

  And the latching means 10 which prevents the shielding board 5 from rising and the horizontal shift | offset | difference is continuously formed in the standing | starting edge 5a and the horizontal edge 5b of a shielding board edge part, as shown in FIGS. And a loose fitting 12 provided in the joint frame 4 and loosely fitted in the notch 11. Further, the locking means 10 are arranged in pairs in two opposite directions of the shielding plate 5.

  The loosely fitting body 12 has a substantially L-shaped cross-sectional shape, and a vertical side 12a1 is attached to the vertical side 4b of the joint frame 4, and a bolt 12b and a nut attached to the horizontal side 12a2 of the bracket 12a. 12c. Further, a through hole 12a3 is formed in the vertical side 12a1 of the bracket 12a, and the bracket 12a is attached to the vertical side 4b of the joint frame 4 through the through hole 12a3 by a mounting bolt 12d.

  In this embodiment, the loosely fitting body 12 is mounted on the joint frame 4 in advance. When the shielding plate 5 is attached, the shielding plate 5 is moved while being inclined, the loosely fitting body 12 and the notch 11 of the shielding plate 5 are opposed to each other, and the loosely fitting body 12 is inserted into the notch 11, and FIG. As shown, the loosely fitting body 12 is loosely fitted to the shielding plate 5. As a result, movement in the frontage direction of the shielding plate 5, that is, movement in the left-right direction in FIG. 3, is suppressed by the upper end portion of the bolt 12 b coming into contact with the rising side 5 a of the shielding plate 5. Further, the movement of the shielding plate 5 in the depth direction is suppressed when the bracket 12 a contacts the end of the notch 11. Further, the vertical movement of the shielding plate 5, that is, the lifting is suppressed by the horizontal side 12 a 2 of the bracket 12 a contacting the horizontal side 5 b of the shielding plate 5.

  According to the present embodiment, the pair of locking means 10 can prevent the shielding plate 5 from floating and shift in the frontage direction and the depth direction, thereby reducing the number of parts compared to the prior art, and thus cost. Can be reduced. The locking means 10 is installed only in two directions of the shielding plate 5 and has a structure in which the loosely fitting body 12 is loosely fitted in the notch 11 at the end of the shielding plate, so that the shielding plate 5 can be easily attached to the cage. It can be attached to the ceiling 3.
