Since an operator may get on the top surface 6 of the top wall 2 at the time of elevator installation or maintenance inspection and place tools or parts, as shown in the figure, an area necessary for the work on the top surface 6 of the top wall 2 is provided. A surrounding area 8 is formed by being surrounded by an elevator car ceiling upper baseboard device 7 so as not to step on the top wall 2 or drop a tool or the like to threaten the safety of work.

  The elevator car ceiling upper baseboard device 7 is composed of a plurality of baseboard elements 9 having the same shape attached to the upper surface 6 of the top wall 2 of the elevator car 1, and surrounds the surrounding area 8 to be enclosed by the upper surface 6 of the top wall 2. Surrounding and partitioning. The top wall 2 of the elevator car 1 is provided with a plurality of substantially square engaging holes 10 at a constant pitch along the outer periphery of the surrounding area 8 (see also FIG. 9).

  As shown in FIGS. 3 to 5, each baseboard element 9 of the elevator car ceiling top baseboard device 7 is made of synthetic resin by extrusion or molding, and has a rectangular plate shape arranged on the top wall 2. A base 11, an elastic engagement piece 12 that extends from the base 11 and elastically engages with the engagement hole 10 of the top wall 2 and fixes the base 11 to the top wall 2, and a right angle from the base 11. And a rectangular plate-like barrier 13 extending so as to rise from the top wall 2. A rib-like reinforcing material 14 is provided between the base 11 and the barrier 13. When the elastic engagement piece 12 is press-fitted into the engagement hole 10 of the top wall 2, the hook is elastically deformed so that the head passes through the engagement hole 10 and the passed head engages with the lower surface 4 of the top wall 2. Thus, it is prevented from coming out (see FIG. 2).

  In the illustrated example, one baseboard element 9 is provided with two elastic engagement pieces 12 and is elastically engaged with two engagement holes 10 of the top wall 2. Four baseboard elements 9 are used in the depth direction, and three baseboard elements 9 are used in the rear width direction. There is no problem even if there is a gap of several centimeters between the baseboard elements 9. The number of baseboard elements 9 used to construct the elevator car ceiling-top baseboard device 1 is appropriately determined according to the shape and dimensions of the elevator car 1 to be applied.
