Stand Laundry Dryer with Coupled Frame and Arm Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing free-standing tumble dryers require separate stretching of the screen and standing frame for setup, complicating handling and increasing production costs.
Innovation Solution
Integration of spreader bars attached to legs and a coupling bar that moves along the mast, coupling the opening and closing movements of the standing frame and sliding joint, allowing for automatic tensioning of support arms with a single movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen and standing frame are stretched out separately for setup, then the dryer can be assembled, but the handling is complicated and production costs increase
Solution Approach 1:
The patent combines the screen support arms and standing frame legs into a single integrated structure where both components share common articulation points and movement mechanisms. The support arms are articulated to the standing frame legs at shared joints, allowing both the screen and frame to be deployed simultaneously through a single user action rather than requiring separate assembly steps.
2Stability of the object's composition
If separate stretching of screen and standing frame is required, then structural independence is maintained, but handling becomes complicated
Solution Approach 1:
The patent segments the drying rack into functionally independent but mechanically coupled components. The screen support arms and standing frame legs are articulated together at shared joints, creating a segmented structure where each component can move independently yet remains connected through common articulation points, allowing simultaneous deployment while maintaining structural independence.

AI summary
The invention relates to a free-standing laundry dryer with a mast (1), several support arms (2) which are articulated on a sliding joint (10) that can be moved along the mast (1) and can be spread open and between which clothes lines (3) run, and with a collapsible Standing frame which has at least three fold-out legs (4) articulated on a leg linkage (5) of the mast (1). The known standing tumble dryers have the disadvantage that the screen for hanging up the items of laundry and the standing frame have to be stretched out separately from one another, which Handling complicated. This improves the invention in that the standing frame has spreader bars (9) which are attached to the legs (4) in an articulated manner with an outer end, and a coupling is provided which controls the movement of the sliding joint (10) with the movement of the spreader bars ( 9) couples.
