US 6,142,286 A · Floor covering for conveying equipment for persons

Abstract

A floor cover for use in conjunction with conveying equipment for persons located at an end of an escalator, moving walkway or the like, has one or more cover elements which can be walked on and which flushly close off, relative to the surrounding flooring, the opening of an under-floor space in which operating equipment is typically located. The cover elements can be lifted and laterally displaced to expose the opening for access to the operating equipment. The cover elements are separably joined together at joint locations. A resilient profile member is located at each joint to prevent the generation of noises and to provide a tight seal between the cover elements against penetrating dirt. The cover can be raised, laterally displaced and rotated away from the opening by means of a multi-part hinge. The turned-up cover elements can, with a support device, be retained in a raised position to form an entry barrier for the exposed opening.

Dependent claims

A floor cover assembly for conveying equipment for flushly closing off an opening of an under-floor space and for providing access to the opening, comprising:

a liftable cover;
a fixed connecting element releasably connected to the cover at a joint;
means for allowing the cover to be raised and pivoted about at least a first longitudinal side of the cover from an initial opening-covering position to afford access to the opening;
and a sound-insulating and sealing intermediate member between the connecting element and the cover at the joint, the sound-insulating and sealing intermediate member constructed as a resilient profile member in the shape of a Greek letter Omega having a projecting enlarged head portion, one of the cover and the connecting element having a longitudinal side with a profile member-accepting detent in the form of a groove having a pair of opposed end faces forming a reduced width groove opening therebetween, the head portion of the profile member being inserted into the groove through the groove opening and being maintained within the groove.
