Abstract
An escalator or moving stairway that is constructed to accommodate oscillation and lateral displacement of a first story relative to a second story of a building between which the escalator or moving stairway extends such as which may occur during an earthquake. The escalator includes novel telescoping connector mechanisms that are connected at one end to a structural support of the building and are connected at the other end to supporting trusses of the escalator in a manner to permit relative movement between the supporting trusses and the floors of the first and second stories of the building.
Claims20
In an escalator having a plurality of moving treads and a supporting truss for supporting the plurality of moving treads, the truss having first and second ends and being disposed between a first floor of a building having a structural support and a second floor of a building having a structural support, the improvement comprising:
- (a) a first connector means for connecting the first end of the supporting truss to the structural support of the first floor in a manner to permit relative movement between the supporting truss and the first floor of the building, said first connector means comprising:
- (i) a first connector connected to the structural support of the first floor;
- (ii) a second connector connected to said first end of said supporting truss;
- and
- (iii) a third connector disposed between said first and second connectors, said third connector having a first end connected to said first connector and having a body portion receivable with said second connector for telescopic movement with respect thereto;
- and
- (b) a second connector means for connecting the second end of the supporting truss to the structural support of the second floor in a manner to permit relative movement between the supporting truss and the second floor of the building.
In an escalator having a plurality of moving treads, means for moving the plurality of moving treads and first and second spaced apart supporting trusses for supporting the plurality of moving treads, each of said first and second the trusses having first and second ends and each of said first and second trusses being disposed between a first floor of a building having a structural support and a second floor of a building having a structural support, the improvement comprising:
- (a) a first connector means for connecting the first ends of said first and second the supporting trusses to the structural support of the first floor in a manner to permit relative movement between the supporting trusses and the first floor of the building, said first connector means comprising:
- (i) a first transverse connector connected to the structural support of the first floor;
- (ii) a first connector connected to said first end of said first supporting truss;
- (iii) a second connector connected to said first end of said second supporting truss;
- (iv) a third connector disposed between said first transverse connector and said first connector, said third connector having a first end connected to said first transverse connector and having a portion telescopically receivable within the said first;
- and
- (v) a third connector disposed between said first transverse connector and said second connector, said third connector having a first end connected to said first transverse connector and having a portion thereof telescopically receivable with the said second connector;
- (b) a second connector means for connecting the second ends of the first and second supporting trusses to the structural support of the second floor in a manner to permit relative movement between the supporting trusses and the second floor of the building.
An escalator disposed between a first floor of a building having a structural support and a second floor of a building having a structural support, said escalator comprising:
- (a) a supporting truss having a first end and a second end;
- (b) a first connector means for connecting said first end of said supporting truss to the structural support of the first floor in a manner to permit relative movement between the escalator and the first floor of the building, said first connector means comprising:
- (i) a first connector connected to the structural support of the first floor;
- (ii) a second connector connected to said first end of said supporting truss;
- and
- (iii) a third connector disposed between said first and second connectors, said third connector having a first end connected to said first connector and having a body portion telescopically movable within said second connector;
- and
- (c) a second connector means for connecting said second end of said supporting truss to the structural support of the second floor in a manner to permit relative movement between the escalator and the first floor of the building.
