Seismic expansion joint cover
First Claim
1. An expansion joint cover installation comprising first and second building members having an expansion gap between them, a first retainer attached to the first building member adjacent the expansion gap, a second retainer attached to the second building member adjacent the expansion gap, an elongated cover having a longitudinal axis, an internal face, an external face and side edges, the cover spanning the expansion gap and overlying at least a portion of the first retainer and at least a portion of the second retainer, at least two first releasable fasteners joining the cover to the first retainer, the first fasteners being spaced apart lengthwise of the cover, at least one slide track attached to the internal face of the cover and extending perpendicular to the longitudinal axis and being positioned to overlie the second retainer, a movable slider received in the slide track for movement along the track, and a second releasable fastener joining the slider to the second retainer.

Abstract
A seismic expansion joint cover for concealing an expansion gap between building members comprises retainers attached to building members on each side of the expansion gap and a cover spanning the expansion gap and overlying at least portions of the first and second retainers and a portion of the building member on at least one side of the gap. The cover is attached to the retainers by releasable fasteners, such as hook and loop fasteners, that enable it to detach completely from the retainers in an earthquake and to be subsequently reattached. One element of each of the fasteners on one side of the gap is attached to a slider that slides along a track affixed to the internal side of the cover to enable normal thermal expansions and contractions of the gap. Tethers keep the cover from falling to the floor and becoming an obstacle to persons moving through the building.

- 1. An expansion joint cover installation comprising first and second building members having an expansion gap between them, a first retainer attached to the first building member adjacent the expansion gap, a second retainer attached to the second building member adjacent the expansion gap, an elongated cover having a longitudinal axis, an internal face, an external face and side edges, the cover spanning the expansion gap and overlying at least a portion of the first retainer and at least a portion of the second retainer, at least two first releasable fasteners joining the cover to the first retainer, the first fasteners being spaced apart lengthwise of the cover, at least one slide track attached to the internal face of the cover and extending perpendicular to the longitudinal axis and being positioned to overlie the second retainer, a movable slider received in the slide track for movement along the track, and a second releasable fastener joining the slider to the second retainer.
- 26. An expansion joint cover installation for concealing an expansion gap between building walls and ceilings, comprising a first building member on one side of the expansion gap, a second building member on the other side of the expansion gap, a first retainer attached to the first building member, a second retainer attached to the second building member, an elongated cover having a longitudinal axis, an internal face, an external face and side edges, the cover having a width transverse to the longitudinal axis such as to span the expansion gap and overlie at least portions of the first and second retainers, and releasable fastener means connecting the cover to the retainers, the releasable fastener means including at least two slide tracks attached in longitudinally spaced-apart relation to the internal face of the cover, each slide track being perpendicular to the longitudinal axis, a movable slider received in each slide track for sliding movement along the track, and a releasable fastener joining each slider to the second retainer.
- 40. A cover unit for an expansion joint cover installation and adapted to be attached to building members on opposite sides of an expansion gap, comprising a elongated cover having a longitudinal axis, an internal face, an external face and side edges, the cover being adapted to span and cover the expansion gap, one element of a releasable fastener affixed to the internal face of the cover at each of a plurality of longitudinally spaced-apart locations adjacent one side edge of the cover, a plurality of slide tracks attached to the internal face of the cover adjacent the other side edge and extending perpendicular to the longitudinal axis, a movable slide member received in each slide track for movement along the track, and one element of a releasable fastener affixed to an internal face of each slide member.
