Abstract

A deflector device prevents jamming of body parts and/or objects between a step belt, which consists of individual steps, and a balustrade pedestal of an escalator. A deflector profile member is fixedly connected with the pedestal plate. The deflector profile member has an opening which serves for the reception of a brush body carrying a brush. A first lug of the deflector profile member has a first projection and a second lug of the deflector profile member has a recess. A snap hook and a second projection are provided at the brush body, wherein the snap hook detents with the first projection and the second projection detents with the recess.

Claims

1. A safety device for an escalator or moving walkway having a step belt with steps or a plate belt with plates for the transport of persons and/or articles and a balustrade which is mounted by means of a balustrade pedestal, the safety device being in the form of a deflector arranged at the balustrade pedestal to prevent the jamming of body parts and/or objects between the step belt or plate belt and balustrade pedestal, the safety device comprising a deflector profile member rigidly affixed to the balustrade pedestal, a brush unit supported by the profile member at a fixed orientation, and snap connection means for releasably connecting the brush unit to the profile member in the fixed orientation.

2. The safety device according to claim 1 wherein the deflector profile member has an opening for receipt of a brush body which carries a brush of the brush unit, the opening being bounded by lugs.

3. The safety device according to claim 1 or claim 2, wherein the snap connection means comprise a first projection at a first lug and a recess at a second lug of the profile member, and a snap hook on the brush body which detents with the first projection and a second projection on the brush body which is received in a non-detenting manner by the recess at the second lug.

4. A safety device for an escalator or moving walkway having a step belt with steps or a plate belt with plates for the transport of persons and/or articles and a balustrade which is mounted by means of a balustrade pedestal, the safety device being in the form of a deflector arranged at the balustrade pedestal to prevent the jamming of body parts and/or objects between the step belt or plate belt and balustrade pedestal, the safety device comprising a deflector profile member rigidly affixed to the balustrade pedestal, first and second brush units supported by the profile member at fixed orientations, and snap connection means for feleasably connecting the brush units to the profile member in the fixed orientations.
