Abstract

In a car compartment of an elevator, a standing end section of a panel is fixed to a standing section of a car floor by a screw member which is fastened by being passed through a ventilation hole and a car floor fastening hole from the car floor side, and therefore an operator can assemble the panel on the car floor from the inside of the car compartment, and the workability of assembling the panel on the car floor is improved.

Claims (43)

1. A car compartment of an elevator, comprising:

a car floor in which edge sections on respective sides include standing sections standing upright; and

a side wall including a plurality of panels each including a lower end section fixed to one of the standing sections by a fastener;

wherein the lower end sections each include a standing end section, and an opposing surface section which is closer to an interior of the car than the standing end section and which is connected to and opposes the standing end section;

the standing end section includes a fastener clearance hole to receive the fastener which is oriented such that a head of the fastener faces the opposing surface section, and the standing end section further includes a car floor fastening hole which extends upwardly from the fastener clearance hole;

the opposing surface section includes a hole which opposes the car floor fastening hole;

the standing end section is fixed to the corresponding standing section by the fastener;

the hole of the opposing surface section is configured to receive a tool from the car floor side such that the tool is insertable through the hole of the opposing surface section and is engageable to tighten the head of the fastener to secure the lower end section of the sidewall to the corresponding standing section of the floor; and

the head of the fastener is larger than the hole of the opposing surface section of the lower end section of the sidewall.

2. The car compartment of an elevator according to claim 1 ,

wherein the panels each includes a first bend section and a second bend section which extend vertically on either side of the panel and are perpendicular to a face of the panel;

the first bend section includes a coupling hole including an insertion hole section and a slit section which is formed extending perpendicularly in a continuous fashion from the insertion hole section and includes a smaller width than a diameter of the insertion hole section;

a coupling protrusion having a projection section of smaller diameter than the diameter of the insertion hole section and of larger diameter than the slit section is provided in the second bend section; and

the adjacent panels are coupled to each other by the projection section sandwiching the first bend section via the slit section.

3. The car compartment of an elevator according to claim 2 , wherein the insertion hole section is provided on an upper side and a lower side of the slit section, in the coupling hole.

4. An assembly method for an elevator car compartment, for assembling the car compartment of an elevator according to claim 2 , the method comprising:

provisionally fastening the fastener to the standing section of the car floor;

inserting the fastening member clearance hole of the standing end section over e fastener and contacting an upper-side end surface of the fastener clearance hole against the fastener;

moving the panel along the upper-side end surface, towards the adjacent panel, until the car floor fastening hole reaches a position directly over the fastener;

moving the panel downwards along the car floor fastening hole and making the head of the fastener border the hole; and

fixing the standing end section to the standing section by fully fastening the fastener by inserting the tool from the car floor side through the hole of the opposing surface section and tightening the head of the fastener to secure the lower end section of the sidewall to the standing section of the floor

wherein, when the fastener contacts the upper-side end surface of the fastener clearance hole, the projection section opposes the insertion hole section, and when the head of the fastener borders the hole, the projection section sandwiches the first bend section via the slit section.

5. The car compartment of an elevator according to claim 2 , wherein the projection section has a step difference section.

6. The car compartment of an elevator according to claim 5 , wherein the insertion hole section is provided on an upper side and a lower side of the slit section, in the coupling hole.

7. The car compartment of an elevator according to claim 1 , wherein a length of the fastener is greater than a distance between the standing end section and the opposing surface section, and when the head of the fastener is viewed in a horizontal direction through the hole from the car floor, the head is partially concealed.

8. The car compartment of an elevator according to claim 1 , wherein the hole of the opposing surface section is a circular ventilation hole which communicates with an outside air, and the hole of the opposing surface section is open when the fastener is tightened.

9. An assembly method for an elevator czar compartment; for assembling the car compartment of an elevator according to claim 1 , the method comprising:

provisionally fastening the fastener to the standing section of the car floor;

inserting the fastener clearance hole of the standing end section over the fastener and contacting an upper-side end surface of the fastener clearance hole against the fastener;

moving the panel along the upper-side end surface, towards the adjacent panel, until the car floor fastening hole reaches a position directly over the fastener;

moving the panel downwards along the car floor fastening hole and making the head of the fastener border the hole; and

fixing the standing end section to the standing section by fully fastening the fastener by inserting the tool from the car floor side through the hole of the opposing surface section and tightening the head of the fastener to secure the lower end section of the sidewall to the standing section of the floor.

10. The car compartment according to claim 1 , wherein:

a diameter of the head of the fastener is larger than a smallest dimension of the hole of the opposing surface section.

11. A car compartment of an elevator, comprising:

a car floor including a main floor section and an edge section that includes a standing section that extends perpendicular to the main floor section;

a side wall including a panel that includes a lower end section configured to be fixed to the standing section by a fastener;

the lower end section includes a standing end section and an opposing surface section spaced apart from the standing end section;

the standing end section includes a fastener clearance hole to receive the fastener and a car floor fastening hole that extends above the fastener clearance hole;

the opposing surface section includes a hole that partially overlaps the car floor fastening hole in a horizontal direction;

the standing end section is configured to be attached to the standing section by the fastener;

the hole of the opposing surface section is configured to receive a tool from m a car floor side to tighten a head of the fastener to attach the lower end section of the sidewall to the standing section of the car floor; and

when the lower end section of the sidewall is attached to the standing section of the car floor, the head of the fastener is at least partially overlapped in the horizontal direction by the opposing surface section.
