Exercise Equipment Position Adjuster with Integrated Latching and Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional position adjusting devices for exercising apparatuses either have gaps due to latching mechanisms or become loose under weight with clamping mechanisms, and combining both mechanisms requires cumbersome operation.
Innovation Solution
A position adjusting device with a telescopic mechanism featuring a control assembly that includes a pressing member, elastic portion, and latching assembly, allowing for secure locking and easy release of the second frame body relative to the first frame body, using a combination of clamping and latching mechanisms without the need for separate operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If latching means are used to lock the position adjusting device, then the structure is simple and easy to manufacture, but gaps remain between frame bodies causing looseness
Solution Approach 1:
The patent combines latching means and clamping means into a single integrated position adjusting device. The latching assembly includes both a latching member that engages with positioning holes and a clamping member that applies continuous pressing force against the frame body, merging the advantages of both locking mechanisms to eliminate gaps while maintaining structural simplicity.
2Stability of the object's composition
If clamping means are used to lock the position adjusting device, then no gaps remain between frame bodies ensuring stability, but the device becomes easy to get loose accidentally under great weight
Solution Approach 1:
The patent merges latching and clamping mechanisms where the latching member provides positive locking by engaging with positioning holes to prevent accidental release under weight, while the clamping member maintains continuous contact to eliminate gaps. This combination ensures both stability and reliability.
Solution Approach 2:
The elastic member pre-compresses the clamping member against the frame body before external loads are applied, ensuring continuous contact and preventing gaps from forming under weight. This pre-positioning cushioning maintains stable contact throughout the loading process.
3Reliability
If both latching lock mechanism and clamping lock mechanism are arranged on the position adjusting device, then both advantages of the two lock mechanisms are obtained, but two separated sets of lock mechanisms require two set of independent actions to be operated which is troublesome
Solution Approach 1:
The patent integrates both latching and clamping functions into a single control assembly that operates through one unified action. The control member simultaneously actuates both the latching member and clamping member, allowing both locking mechanisms to be engaged or released with a single operational movement, thus maintaining reliability while improving ease of operation.
Solution Approach 2:
The control assembly serves multiple functions: it operates both the latching mechanism and clamping mechanism, and also controls the elastic member's compression. This multi-functional design eliminates the need for separate operations for each locking mechanism.
4Reliability
If the pressing member is moved to the first tightening position to press the second frame body, then the relative position is securely locked, but the elastic portion must be compressed increasing the distance between deflection portion and axle portion
Solution Approach 1:
The elastic portion is designed to dynamically compress and expand based on the operational state. During tightening, the elastic portion compresses to allow the pressing member to reach the first tightening position, providing reliable locking. During release, the elastic portion expands to push the pressing member away, enabling easy disengagement. This dynamic behavior maintains reliability while managing the distance variation.

Function Achieved in This Case
Enables quick and secure adjustment of the relative position of exercise equipment frames, ensuring stability under weight while simplifying the locking and releasing process.
Implementation Method 1
the elastic portion configured to provide an elastic restoring force for biasing the deflection portion away from the axle portion
Implementation Method 2
An elastic member is mounted between the first frame body and the latching assembly for being configured to bias the latching assembly to the lock position

AI summary
A position adjusting device for exercising apparatus includes a first frame body and a second frame body that are relatively displaceable in a longitudinal direction. A pressing member and a control assembly are respectively disposed at opposite sides of the first frame body. The control assembly has an axle portion and a deflection portion with an elastically extendable distance therebetween. At least one connecting arm connects the deflection portion and the pressing member. The control assembly is rotatable about the axle portion, so that the deflection portion is movable from a first position through a second position to a third position. When the deflection portion is in the first position, the distance is between a maximum length and a minimum length. When the deflection portion is in the second position, the distance is the minimum length. When the deflection portion is in the third position, the distance is the maximum length.
