AI Technical Summary
Technical Problem
Existing hydraulic pump actuation devices for variable-height swivel chairs are indirect and asymmetrical, leading to significant twisting moments and large dimensions, which affect functionality and aesthetics.
Method used
A direct actuation device for a pedal-operated hydraulic pump with a brake for blocking chair rotation, featuring a pedal lever with a thrust block and two-armed bracket, directly applying force to the piston head, eliminating the need for a small push arm and reducing component dimensions.
Benefits of technology
The solution provides direct actuation with reduced dimensions, eliminating twisting moments and play due to wear, enhancing functionality and aesthetic appeal while maintaining compactness.
