Abstract
A modular room extender for recreational vehicles, modular homes and the like utilizing a pair of axially displaceable slide rods having outer ends attached to the extendible room. The slide rods are mounted within a bracket which includes spaced parallel guides wherein the bracket slide rods and guides define a modular unit which may be installed as a complete assembly. The slide rod's inner ends are free and not connected to other structure, and a reversible electric motor operates a gear and rack system for extending and retracting the slide rods. A stamped metal rack of economical construction is attached to each slide rod.
Claims8
A pre-assembled modular extender for installation as a unit comprising, in combination, a support bracket adapted to be separately mounted as a unit upon primary support structure, said bracket including a pair of substantially parallel elongated spaced guides each having a longitudinal axis, reinforced braces transversely extending between and affixed to said guides maintaining said guides in a substantially rigid parallel spaced relationship and alignment, an elongated slide rod supported within each guide for axial movement therein, each slide rod having a free inner end and an outer end, a slide rod operator affixed to each slide rod, and a reversible slide rod actuator operatively connected to each slide rod operator for selectively translating the associated slide rod in a predetermined axial direction, whereby said support bracket comprises a separate structurally integral unit with respect to the primary support structure maintaining the assembly, rigidity and alignment of said spaced guides.
A pre-assembled modular extender for installation as a unit comprising, in combination, a support bracket adapted to be separately mounted as a unit upon primary support structure, said bracket including a pair of substantially parallel elongated spaced guides each having a longitudinal axis, reinforced braces transversely extending between and affixed to said guides maintaining said guides in a substantially rigid parallel spaced relationship and alignment, an elongated slide rod supported within each guide for axial movement therein, each slide rod having a free inner end and an outer end, an elongated gear rack affixed to each said slide rod substantially parallel thereto, a gear rotatably mounted on each said guide meshing with the rack attached to the slide rod within the associated guide, a reversible electric motor mounted on said support bracket and drive shaft means interconnecting said motor with said gears, whereby said support bracket comprises a separate structurally integral unit with respect to the primary support structure maintaining the assembly, rigidity and alignment of said spaced guides.
