Embodiment Construction

[0017] Hereinafter, embodiments of the elevator car according to the present invention will be described with reference to the drawings.

[0018] Such as figure 1 and figure 2 As shown, the elevator car 1 of the present embodiment is formed into a cuboid box shape by the car floor 2, the top plate 3 opposite to the car floor 2, the outer side plate 4 and the inner side plate 5: the outer side plate 4 The outer wall is formed by extending vertically between the car floor 2 and the roof 3. The inner side plate 5 is fixed to the outer side plate 4 and extends vertically between the car floor 2 and the roof 3 to form an outer wall. form the inner wall.

[0019] In addition, if image 3 and Figure 4 As shown, a plurality of outer side panel reinforcements 6 and inner side panel reinforcements 7 are provided inside the outer side panel 4 and the inner side panel 5 for improving the rigidity of the side panels.

[0020] The width dimensions of the outer side plate 4 and the in...

Abstract

Provided is an elevator car such that noise, in particular structure-borne noise, in the car during elevator travel can be reduced. The elevator car (1) is configured from two layers of an exterior side plate (4) and an interior side plate (5), and resonance in the side plates is controlled and sound insulation is improved therein by having different measurements for the widths of the exterior side plate (4) and the interior side plate (5), and by arranging the exterior side plate (4), the interior side plate (5), exterior side plate reinforcements (6), and interior side plate reinforcements (7) in a direction perpendicular to the side plate surface with the positions thereof being offset from each other.

Description

technical field [0001] The invention relates to a sound insulation technology for a car of a high-speed elevator, in particular to an elevator car capable of reducing solid-borne sound. Background technique [0002] As background art in this technical field, JP-A-11-139727 (Patent Document 1) is known. This gazette discloses a technique in which the side plate of an elevator car is divided into an inner side plate and an outer side plate, and vibration-proof rubber is provided between the inner side plate and the outer side plate. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Application Laid-Open No. 11-139727 [0006] High-speed elevators generate various noises due to their high-speed movement in the vertical direction in the hoistway. In order to cope with airborne sound such as fluid sound (wind whistle) caused by turbulent airflow around the elevator car and noise generated by equipment in the hoistway, soundpro...
