No-lift install system
View Patent ↗A rolling cart has a wheeled frame, telescoping vertically extendable members with glide strips, and a tiltable frame having glide strips interspersed with transfer balls to easily slide slabs or sheet materials for construction such as when installing countertops. A method is also described for measuring a minuend desired install height, subtracting a geometrically predetermined subtrahend, and adjusting the height from a floor surface to a pivot axis on the cart to equal the difference, said adjustment being effected by powered lifting means incorporated or ancillary to the cart.
1. A slab moving device comprising:
a rolling cart;
a generally planar frame, tiltably mounted on said cart; said frame tiltable between a horizontal and a vertical position;
at least one vertically extendable strut affixed to said rolling cart with said tiltable frame rotatably coupled to said vertically extendable strut so as to define a vertically adjustable pivot axis of said frame; and
at least one transit chock spaced apart from at least one of said vertically extendable strut to form a gap of a predetermined width, into which can be received said tiltable frame.
2. The slab moving device of claim 1 , further comprising: an operable strut extending mechanism.
3. The slab moving device of claim 2 , wherein said operable strut extending mechanism further comprises an extendable member which is also a damping member.
4. The slab moving device of claim 1 , wherein said strut extending mechanism is operated by a battery-powered motor.
5. The slab moving device of claim 4 , wherein said strut extending mechanism and said battery-powered motor are operated by remote control.
6. The slab moving device of claim 4 , wherein said strut extending mechanism and said battery powered motor are controlled by at least one switch.
7. The slab moving device of claim 6 , wherein at least one of said at least one switch is affixed to said tiltable frame.
8. The slab moving device of claim 1 , wherein said strut extending mechanism comprises a threaded shaft.
9. The slab moving device of claim 8 , wherein an end of said threaded shaft comprises a hexagonal cross-section.
10. The slab moving device of claim 1 , wherein said tiltable frame is fabricated from tubing in which at least one tube end is capped off by a bumper.
11. The slab moving device of claim 1 , further comprising:
adhesive-backed high-friction material affixed to at least one transit chock.
12. The slab moving device of claim 1 , further comprising:
adhesive-backed high-friction material affixed to said rolling cart.
13. The slab moving device of claim 1 , further comprising:
a plurality of support blocks made of a compliant material affixed to said rolling cart.
14. The slab moving device of claim 1 , further comprising:
at least one extendable member connected between said tiltable frame and said at least one vertically extendable member,
wherein said at least one extendable member further comprises a mechanical damper.
