Medical Wall Mount Lever Lock for Secure Easy Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall brackets for medical appliances face difficulties in securely retaining the appliance while allowing for easy removal, particularly in mobile settings where activation forces can be high and operation challenging.
Innovation Solution
A wall bracket with a multi-arm lever mechanism and a restoring arrangement, featuring a lever with a main and auxiliary arm, and a restoring spring, allows for secure retention and easy release of medical appliances, using a dovetail guide for positive-locking connection and incorporating electrical connections for energy supply and networking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a push-button locking mechanism is used to secure the appliance, then secure retention is achieved, but the operating forces become relatively high and activation becomes difficult
Solution Approach 1:
The locking element is integrated into a lever that can be moved between different positions (open and locking positions). This dynamic mechanism allows the locking element to be engaged or disengaged by moving the lever, providing secure retention when locked while enabling easy release when the lever is moved to the open position.
Solution Approach 2:
A restoring arrangement with a restoring spring is provided that automatically changes the position of the locking element. When the appliance-specific connection element is coupled to the wall bracket, the restoring spring presses the locking element out of the locking position into the open position without requiring manual activation, thereby reducing operating forces.
2Ease of operation
If the locking element is pressed out automatically by a restoring arrangement, then easy release is achieved, but the locking security may be compromised
Solution Approach 1:
The system dynamically adapts its behavior based on the coupling state. When the appliance is coupled, the restoring arrangement automatically moves the locking element to the open position for easy release. When the appliance is not coupled, the lever can be manually moved to the locking position to engage the locking element, ensuring locking security when needed.
Solution Approach 2:
The restoring arrangement automatically performs the release function without requiring manual intervention. The restoring spring is pre-loaded to automatically press the locking element out of the locking position when the connection element is coupled, enabling self-service release while maintaining security when the lever is in the locking position.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides secure, easy-to-operate, and vibration-resistant mounting of medical devices in mobile environments, ensuring reliable retention and easy detachment without high operational forces, while allowing for energy supply and networking.
Implementation Method 1
there is arranged in the housing a restoring arrangement which cooperates with the lever, wherein the restoring arrangement comprises in particular a restoring spring which cooperates with the auxiliary arm
Implementation Method 2
the lever has a restoring arm, wherein the restoring arrangement in particular has a damper element which cooperates with the restoring arm. The restoring arm can in contrast remain in the housing and together with the restoring arrangement be covered thereby. The damper element damps excessively rapid restoring movement and thus ensures lower material loads.

AI summary
The invention relates to a wall bracket (1) for releasably securing a medical appliance and an appliance-specific connection element. The wall bracket comprises a housing (2) which has a front side (3), a rear side (16), two longitudinal sides (11a, 11b), a lower side (5) and an upper side (6). A connection geometry (4) for an appliance-specific connection element is arranged at the front side (3). A locking element (24) can be moved through an opening (23) of the connection geometry (4), wherein the locking element (24) can be moved by means of a lever (12) which is supported in the housing (2) between an open position and a locking position.
