Review of Concept Designs
• Telescoping tube rails• Cable lift platform• Wheeled cart (detachable) • Conveyor belt• Scissor lift
The Attic LiftPerspective View – Lowered Position Perspective View – Raised Position
Application number: 11/238,415; Publication number: US 2007/0114098 A1; Filing date: Sep 29, 2005; Inventor: Jason Hartley; www.theatticlift.com
The Attic Lift
• Upper level frame and winch raise and lower a platform by winding and unwinding cables
• No support or guidance structure in lower level• Pros:
o Many sizes (200 lbs – 750 lbs)o Durability (so they claim)
• Cons:o Must have stairs, not an elevator for peopleo Objects can fall off
The SpaceLift 6000
By SpaceLift Products, Inc. Patented: Nov. 8, 2005www.spaceliftproducts.com No. 6,962,236 by Jay Penn
The SpaceLift 6000
• Specialized staircase, mounting frame, and trolley attached to a winch via 4 cables.
• Trolley and mounting frame roll to side once at top to allow access.
Pros:• Level platform at chest height for loading• Load management system detects interference
Cons:• 4 Cables complicates lifting process• Single size compatibility
Combination Loft and Ladder Lift(patent pending)
Inv. Daniel Harry Corby Quare Filing Date: Nov. 29, 2006Application #: 11/564,534 Publication: US 2007/0269303
Combination Loft and Ladder Lift
• Uses a custom ladder with a carriage and crane system to move packages up attic stairs.
• Crane Actuates to move said package when carriage reaches top of the attic stairs.
Pros:• Solution to handling the object when reaches the top.• Allows for unobstructed use of stairs by people.• Load management system detects interference
Cons:• Requires vertical room for installation.• Does not provide any package control and item may fall off
platform.• Obstructs the landing area for humans as they climb the
ladder
Overhead Platform Elevation Device
Inventor: Douglas J. HughesPatent number: 5,667,035
Filing date: Oct 19, 1995Issue date: Sep 16, 1997
Overhead Platform Elevation Device
• Assembly is positioned in its own ceiling cutout, separate from attic stairs
• Device consists of platform raised and lowered by cables within telescopic support structures
• Cables are wound on opposed pulleys, and driven by a motor to power the vertical displacement
• Pros:o Maintains orientation of objecto Does not block or interfere with laddero Self Storing
• Cons:o Requires second cutout in attico Cannot be retrofit
Overhead Platform Elevation Device
Inventor: Randy SpraguePatent number: 5,626,208
Filing date: July 13, 1995Issue date: May 6, 1997
Screw Lift Device
• Again, assembly is positioned in its own ceiling cutout, separate from attic stairs
• Device consists of platform raised and lowered by screw within permanent rail structure
• Motor drives the screw to raise and lower the platform
• Pros:o Maintains orientation of objecto Does not block or interfere with laddero small vertical foot printo simple design
• Cons:o Permanent, or if not requires a lot of spaceo high cost
Selection Analysis
1. Wheeled Cart (relative score = 1.00)- Simple, effective design and easy to use 2. Cable lift (relative score = 0.98)- Very capable, but more complicated 3. Conveyor belt (relative score = 0.95)
4. Product: Spacelift 6000 (relative score = 0.91)
5. Telescoping rails (relative score = 0.87)
6. Patent pending: Combo lift and ladder (relative score = 0.83)
7. Scissor lift (relative score = 0.68)- Less reliable and complex structure
