Abstract
An elevator has deflecting rollers integrated in the car floor. The supporting and driving means is guided in the car floor through a floor channel. A cover serving as protection covers the supporting and driving means running in and running out at the deflecting roller. The hood-shaped cover can be snapped onto the axle of the deflecting roller.
Claims11
An elevator including an elevator car and a counterweight that are movable in an elevator shaft and are connected by a supporting and driving means comprising:
- at least one deflecting roller integrated in the elevator car or in the counterweight and engaged by the supporting and driving means;
- and
- a cover mounted adjacent said at least one deflecting roller and covering a portion of the supporting and driving means engaging said at least one deflecting roller, said cover including an arcuate wall extending between and connecting a pair of side panels, said cover not contacting the supporting and driving means, said arcuate wall covering a portion of the supporting and driving means, and said arcuate wall and said pair of side panels within a close proximity of said at least one deflecting roller thereby preventing the supporting and driving means from completely disengaging from said at least one deflecting roller.
A method of improving the safety of an elevator having an elevator car and a counterweight movable in an elevator shaft and connected by a supporting and driving means guided over at least one deflecting roller comprising the steps of:
- a. integrating the at least one deflecting roller in one of the elevator car and the counterweight;
- b. providing a cover having an arcuate wall extending between and connecting a pair of side panels and mounting the cover to a portion of the supporting and driving means engaging the at least one deflecting roller, the cover not contacting the supporting and driving means, the arcuate wall covering a portion of the supporting and driving means, and the arcuate wall and the pair of side panels within a close proximity of the at least one deflecting roller thereby preventing the supporting and driving means from completely disengaging from the at least one deflecting roller;
- and
- c. detenting the cover to the at least one deflecting roller.
An elevator including an elevator car and a counterweight that are movable in an elevator shaft and are connected by a supporting and driving means comprising:
- a deflecting roller integrated in the elevator car or in the counterweight and engaged by the supporting and driving means;
- a cover mounted adjacent said deflecting roller and covering a portion of the supporting and driving means engaging said deflecting roller, said cover not contacting the supporting and driving means, and said cover within a close proximity of the at least one deflecting roller thereby preventing the supporting and driving means from completely disengaging from said deflecting roller;
- and
- said cover including a pair of Jugs engaging an opening at a support of said deflecting roller and said cover having recesses formed in a pair of side panels which fit on an axle of said deflecting roller, each said side panel partially covering an adjacent side of said deflecting roller.
