Abstract
Two sliding doors are supported to hang vertically, without floor guides for their lower edges, by offsetting the planes of the doors relative to the planes of the supporting tracks in directions so that the lower portions of the doors press towards each other. Intermediate doors, in three or more door assemblies, may be supported to hang vertically. Arms, attached to doors and supporting rollers bearing on the tracks, are interfingered, thereby avoiding general arm interference and maintaining lapping of doors.
Claims10
The improvement in a sliding door assembly in which at least first and second similar sliding doors are hung by roller means depending from track means, comprising:
- a. said track means including at least first and second spaced apart tracks, said first door being hung by its roller means solely from said first track and said second door being hung by its roller means solely from said second track,
- b. each door being hung with its central upright plane spaced from the vertical plane which includes the track from which it is hung so that the lower margin of the door will tend to swing toward that vertical plane, and
- c. the vertical plane which includes said first track being spaced from the central upright plane of said first door in the direction of the central upright plane of the second door and the vertical plane which includes said second track being spaced from the central upright plane of said second door in the direction of the central upright plane of the first door, whereby the lower margins of said doors tend to swing into abutment and whereby said doors tend to be stabilized in normal position in generally vertical orientation with their lower margins pressed against each other with equal forces, and said doors have combined resistance to displacement of the lower portions of the doors from said normal position in directions normal to said planes due to shifts of door centers of gravity in a manner having combined resistance to that displacement, without a requirement for door guides therebelow.
The improvement in a sliding door assembly in which first and second sliding doors and at least one intermediate sliding door are hung by roller means depending from track means, comprising:
- a. said intermediate door being hung from said track means with its central upright plane between the central upright planes of said first and second doors and said intermediate door at least partly lapping said first and second doors in all positions thereof, said intermediate door being hung by its roller means in a balanced position relative to the track means so as to normally assume a vertical disposition,
- b. said track means including at least first and second spaced apart tracks, said first door being hung by its roller means solely from said first track and said second door being hung by its roller means solely from said second track,
- c. each of said first and second doors being hung with its central upright plane spaced from the vertical plane which includes the track from which it is hung so that the lower margin of the door will tend to swing toward that vertical plane, and
- d. the vertical plane which includes said first track being spaced from the central upright plane of said first door in the direction of the central upright plane of the second door and the vertical plane which includes said second track being spaced from the central upright plane of said second door in the direction of the central upright plane of the first door, whereby the lower margins of said doors tend to swing into abutment with said intermediate door and whereby the doors tend to be stabilized in normal position in generally vertical orientation with their lower margins pressed against each other and said doors have combined resistance to displacement of the lower portions of the doors from said normal position in directions normal to said planes due to shifts of door centers of gravity in a manner having combined resistance to that displacement.
