Abstract
The present invention provides modular sliding door rollers for use in sliding doors. The modular sliding door rollers have a major roller unit and one or more minor roller units modularly connected together in series. The major and minor roller units have a roller which is adjustable to extend out of and retract into the major and minor roller units by adjusting a roller adjuster on the major roller unit. Two pairs of partially overlapping and divergent roller axle slots are provided on each of the major and minor roller units to provide for extension and retraction of the rollers.
Claims27
A modular sliding door roller comprising:
- a major roller unit having a major connection end, a first roller adjustably extending out of an interior of the major roller unit, and a roller adjustor linked to the roller;
- and
- at least one minor roller unit having opposing first and second minor connection ends, the first minor connection end engaged with the major connection end of the major roller unit, and a second roller adjustably extending out of an interior of the minor roller unit, the second roller linked to the roller adjustor by the major connection end being engaged with the first minor connection end.
A modular sliding door roller comprising:
- a major roller unit comprising:
- a major inner housing slidably positioned inside of a major outer housing, the major outer housing defining a pair of opposed major outer axle slots, the major inner housing defining a pair of opposed major inner axle slots partially overlapping the major outer axle slots;
- a major roller having an axle positioned in the overlapped pairs of the major inner and outer axle slots;
- and
- a roller adjustor threadingly engaged with the major inner housing;
- and
- a minor roller unit comprising:
- a minor inner housing slidably positioned inside of a minor outer housing, the minor outer housing defining a pair of opposed minor outer axle slots, the minor inner housing defining a pair of opposed minor inner axle slots partially overlapping the minor outer axle slots, the minor outer housing removably connected to the major outer housing and the minor inner housing removably connected to the major inner housing;
- and
- a minor roller having an axle positioned in the overlapped pairs of the minor inner and outer axle slots.
A method of making a sliding door roller comprising the steps of:
- providing a major roller unit having a modular major connection;
- providing a selected number of minor roller units, each minor roller unit having first and second modular minor connections;
- connecting one of the minor roller units to the major roller unit by connecting the first modular minor connection to the modular major connection;
- and
- connecting each of remaining minor roller units to an adjacent minor roller unit by connecting the first modular minor connections to the second modular minor connections.
A sliding door roller comprising:
- a major roller unit having and end, a major connector, and a first roller extending out of an interior of the major roller unit;
- and
- a minor roller unit having an end and a first minor connector, the first minor connector having a first position separated from the major connector of the major roller unit prior to assembly of the major roller unit and the minor roller unit together and a second position connected to the major connector of the major roller unit such that the ends of the major and minor units are facing each other after assembly of the major roller unit and the minor roller unit together, and a second roller extending out of an interior of the minor roller unit.
