Elevator system

An elevator system, comprising:

• an elevator car including a front portion defining an entranceway;
• said front portion including a car frame having an upper beam member, said upper beam member having a substantially inverted U-shaped cross-sectional configuration having depending leg portions, with the ends of the depending leg portions being inwardly flanged;
• a transom in said elevator car below said upper beam member;
• door means;
• door mounting means mounting said door means for slideable movement adjacent to the front portion of said elevator car to open and close said entranceway;
• door operator means operably connected to said door means, said door operator means being mounted below said upper beam member and concealed from view within the elevator car by said transom;
• said door operator means including a substantially U-shaped mounting bracket having upwardly extending leg portions, the ends of which are outwardly flanged, with certain of the components of said door operator means depending from the upper beam member via said U-shaped mounting bracket;
• and resilient vibration absorbing means;
• said flanges on the U-shaped mounting bracket being secured to the flanges of the upper beam member via said resilient vibration absorbing means.

An elevator system, comprising:

• an elevator car including a front portion defining an entranceway;
• said front portion including a car frame having an upper beam member;
• a transom in said elevator car below said upper beam member;
• door means;
• door mounting means mounting said door means for slideable movement adjacent to the front portion of said elevator car to open and close said entranceway, said door mounting means including a metallic rod which defines a guide track, and linear slide ball bearing bushings configured to at least partially encircle and slide on said metallic rod, said metallic rod including end and intermediate support members, and said linear slide ball bearing bushings having a substantially C-shaped cross-sectional configuration, with the support members and linear slide ball bearing bushings being dimensioned to preclude interference therebetween as the linear slide ball bearing bushings move past the intermediate support members;
• and door operator means operably connected to said door means, said door operator means being mounted below said upper beam member and concealed from view within the elevator car by said transom.

An elevator system, comprising:

• an elevator car including a front portion defining an entranceway and a platform having a nose at the front of the elevator car,
• said front portion including a car frame having an upper beam member;
• said upper beam member having first and second ends and an opening intermediate its ends,
• a tunnel structure disposed to extend through the opening in the upper beam member spaced inwardly from the nose of the platform to divide the upper beam member into first and second portions,
• a transom in said elevator car below said upper beam member;
• door means;
• door mounting means mounting said door means for slideable movement adjacent to the front portion of said elevator car to open and close said entranceway;
• and door operator means operably connected to said door means, said door operator means being mounted below said upper beam member and concealed from view within the elevator car by said transom,
• said door operator means including first and second portions disposed adjacent to the first and second portions, respectively, of the first beam member, and means interconnecting said first and second portions of the door operator means, with said interconnecting means being disposed in the space between the nose of said platform and said tunnel structure.
