Bed Side Rail with Telescopic Rods for One-Handed Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed side rails are either limited to collapsible or telescopic designs, requiring two-handed operation and lacking flexibility in position adjustment, which can be inconvenient for users needing assistance with bed access and visibility in domestic settings.
Innovation Solution
A bed side rail with rotatable arms and telescopic rods that allow for multiple position adjustments, including extended and retracted configurations, with a locking mechanism for secure use and compact storage, enabling one-handed operation and concealment within the bed frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the side rail is made collapsible to a folded position, then the side rail can be compacted next to the bed for storage and nursing access, but it requires two-handed operation (one hand for button/lever, one hand for folding) which reduces ease of operation
Solution Approach 1:
The patent combines the collapsing function and telescopic extension function into a single integrated mechanism. The side rail can be collapsed to a compact position and simultaneously extended to a longer position using the same mechanical structure, eliminating the need for separate operations and achieving one-handed control.
Solution Approach 2:
The side rail mechanism is designed to perform multiple functions: it can be collapsed for storage, extended for additional support, and used in various positions. The same structural elements enable both collapsing and telescopic movements, making the device multi-functional and reducing operational complexity.
2Length of moving object
If the side rail is made telescopic to extend length, then it can aid less mobile people to get in and out of bed, but it cannot be collapsed when in the extended position which limits adaptability
Solution Approach 1:
The side rail employs dynamic mechanisms that allow it to change its configuration freely. The telescopic rods are designed to extend and retract while maintaining the ability to collapse the entire structure. The hinges and connection points enable continuous movement between extended and collapsed states, providing dynamic adaptability rather than fixed positions.
3Shape
If the side rail is collapsed in storage position, then it can be hidden behind the bed for aesthetic purposes, but existing designs require complex mechanisms that reduce reliability
Solution Approach 1:
The side rail mechanism is designed to be self-sufficient and self-locking. The telescopic rods and hinge connections automatically maintain the rail in its extended or collapsed position without requiring additional locking mechanisms or complex control systems. The mechanical design inherently provides stability and reliability while achieving the desired concealed shape.

AI summary
Side rail for a bed (1) characterised in that the side rail (7) comprises two arms (9) for the rotatable attachment of the side rail (7) to the bed (1), said arms (9) being provided to this end with a rotation point (10) on one end, whereby the arms (9) are connected to each other by at least two telescopic rods (11a, 11b, 11c) which are connected to said arms (9) by means of hinges (12a, 12b, 12c), such that the arms (9) are rotatable between at least a raised use position, whereby the side rail (7) is in use, and a collapsed storage position, whereby the side rail (7) is collapsed, whereby the arms (9) together with their rotation point (10) are movable relative to each other and whereby the side rail (1) in at least two positions of the arms (9) is rotatable between at least the raised use position and the collapsed storage position.
