Description

  The present invention relates to an elevator car ceiling, and more particularly, to an illumination plate mounting structure that distributes light by covering a light source mounted on the ceiling of a car room from below.

  The conventional elevator car ceiling is suspended from the canopy at a location close to the side wall of the cab so that the side plate surrounds the lighting equipment attached to the canopy, and the lighting plate projects horizontally from the lower end of the side plate. It is arranged so as to cover the light source by being supported by the provided support part, and a joint is constructed between the illumination plates (see, for example, Patent Document 1).

Japanese Patent No. 4515788

  In a conventional elevator car ceiling, the joints are not removable from the car room with the illumination plate disposed. Therefore, when cleaning or replacing lighting equipment, release the lighting plate from the car room, tilt the lighting plate in the interior space of the suspended ceiling, rotate it, and between the side plates and joints or between joints. Pull it into the car room. Then, after the cleaning is completed or the lighting device is replaced, the lighting plate is inserted into the internal space between the side plate and the joint or between the joints, and the lighting plate is supported by the support portion of the side plate to fix the lighting plate. Thus, the work for attaching and detaching the illumination plate becomes complicated.

  Also, when pulling out the lighting plate into the car room or inserting the lighting plate into the interior space of the suspended ceiling, the internal space is widened so that it does not hit the design surface of the lighting equipment or joints. It was necessary to increase the cost, that is, to increase the depth of the internal space. Therefore, when the ceiling of the existing cab is changed to a conventional elevator car ceiling, the ceiling height is lowered, giving the passenger a feeling of cramping and urgency.

  The present invention has been made to solve such a problem, and in a state where the lighting plate is installed, the joint can be removed, and the lighting plate can be removed without widening the internal space of the suspended ceiling. The purpose is to obtain an elevator car ceiling that can be easily attached and detached.

  Each of the elevator car ceilings according to the present invention has a base portion and a support portion extending perpendicularly from one end of the base portion, and the support portion faces downward so as to surround the lighting device attached to the canopy. A plurality of side plates suspended from the canopy, and a plurality of illumination plates installed so as to cover the illumination device, are installed between the side plate supporting portions facing each other, and a gap between adjacent illumination plates is blocked. The joint is detachably attached from the car room in a state where the lighting plate is installed.

According to this invention, the joint is detachably attached from the car room in a state where the lighting plate is installed. Therefore, after the joint is removed, the illumination plate can be removed and the illumination plate can be attached, and the illumination plate can be easily attached and detached during cleaning or replacement of the illumination device.
Moreover, it is not necessary to make the lighting plate in the suspended ceiling slant or rotate, and the depth of the suspended ceiling can be reduced. Therefore, when the ceiling of the existing cab is changed to the book cab ceiling, the ceiling height becomes high, and a feeling of cramping or urgency is not given to the passengers.
