Over-Bed Tables & Nightstands Gas Springs - Product Introduction
Overview
Land engineers compact, quiet gas springs (also called gas struts or lift supports) that make over-bed tables, lift-top nightstands, and bedside cabinets effortless to raise, position, and lower. Tuned damping ensures gentle, controlled motion near patients-no slam, no bounce-while low-friction seals deliver a premium "light touch" feel during night shifts. Typical ranges cover 4–12 in (100–300 mm) stroke and 60–400 N (14–90 lbf) force, custom-matched to your top size, load, and linkage geometry.
Suitable Types for This Application (place below Overview on your page)
Compression Gas Springs (damped) - primary lift for height/tilt tops and lids
Locking Gas Springs (rigid or elastic) - precise height/angle hold for reading/eating positions
Traction (Tension) Gas Springs - return/counter-pull in short envelopes or sliding tops
Hydraulic Dampers (standalone) - add speed control to drawers, flip panels, or swing arms
Micro/Mini Gas Springs - soft-open/soft-close for small service doors and accessory lids
What Makes Them Stand Out
Quiet, patient-safe motion: Metered oil damping and end-of-stroke cushioning prevent sudden drops next to the bed.
Fingertip positioning: Low stick–slip seals deliver smooth starts/stops for precise height and angle setting.
Slim packaging: High energy density fits inside narrow columns and thin lift brackets-no bulky counterweights.
Hygiene-ready: Stainless steels (316/304) or black-nitrided rods resist corrosion and tolerate frequent disinfectant wipe-downs.
Drop-in integration: Ball sockets, eyelets, clevises, and M6–M10 threads match common furniture hardware.
Functional Benefits
Better bedside ergonomics for nurses and caregivers; less effort to raise loaded tops (meals, laptops, monitors).
User comfort & safety thanks to soft-close behavior around fingers and edges.
Night-shift friendly acoustics-reduced squeak and rebound near sleeping patients.
Lower life-cycle cost via wear-resistant rods, stable force curves, and serviceable end fittings.
Typical Specifications & Options
Stroke: 100–300 mm (4–12 in)
Force: 60–400 N (14–90 lbf), extended ranges available
Locking: Rigid-locking (fixed height/angle) or elastic-locking (compliant comfort); lever or cable release
Damping: Soft-open/soft-close with adjustable orifice profiles; end-cushioning on heavy tops
Materials: SS316/SS304 or black-nitrided steel rods/tubes for corrosion and wear resistance
End Fittings: Ball studs Ø8–10 mm, eyelets, clevis forks; M6/M8/M10 threads
Marking/Docs: Laser-etched force/stroke, QR for spares; 2D/3D CAD, torque guidance, force–angle curves, PPAP/traceability
Application Map
Lift-top over-bed tables - damped compression spring assists vertical travel; optional locking holds reading/eating height.
Tilting work surfaces - locking spring fixes angle for tablet use; elastic type adds slight compliance for comfort.
Slide-out dining leaves & laptop trays - traction spring or mini damper manages extension/retraction speed.
Lift-top nightstands & storage lids - compact damped strut prevents slam and holds open for access.
Soft-close drawers & side panels - standalone hydraulic damper smooths motion and reduces impact noise.
Design & Integration Notes
Force target: Start at 35–55% of the peak moment about the pivot to achieve a "light yet controlled" feel; tune in 10–20 N steps.
Kinematics: Place the spring so its line of action approaches 90° to the lever at mid-travel for maximum torque efficiency.
Orientation: Mount rod-down at rest to keep the main seal oil-wetted and extend service life.
Pinch-risk control: Use end-cushioning and soft-close profiles around user touchpoints; add secondary stops on heavy tops.
Environment: Specify force at 20 °C; verify feel across ward temperatures and cleaning protocols.
Materials & Cleaning Compatibility
SS316 for aggressive cleaners or coastal humidity; SS304 for general hospital/facility environments.
Black-nitrided rods provide hard, low-glare surfaces that resist scratches from trays and hardware.
Seal stacks selected for low friction and compatibility with IPA, quats, and peroxide wipes.
Quality & Validation
100% end-of-line force & stroke verification
Optional salt-spray, cleaner exposure, drop/impact, and life-cycle testing (50k–100k+ actuations)
Batch traceability and documentation aligned with healthcare furniture OEM requirements
Integration Support
From concept to pilot builds, Land provides force sizing, linkage optimization, CAD models, prototype kits, and on-line tuning to lock in the exact hand-feel and acoustic profile you want. We can standardize spring bodies and fittings across table and cabinet families to simplify purchasing and service.
