Door Hinge Anchor Mount for High Resistance Exercise Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise systems face challenges in supporting high resistance loads, as they often require mechanisms to securely attach flexible members or body weight, which traditional door hinges cannot effectively manage.
Innovation Solution
A door anchor system that replaces the original hinge pin with a longer one and includes a mount with knuckles to create a channel, allowing the anchor to securely attach exercise systems to a door hinge, using adapter shims for compatibility with various hinge sizes and incorporating a clip for attaching exercise equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional door hinge is used to support exercise equipment, then the door can rotate freely, but it cannot support high resistance loads of hundreds of pounds
Solution Approach 1:
The hinge assembly is divided into separate components: the original hinge leaves remain on the door and frame, while a separate mount with knuckles is attached to the hinge pin. This segmentation allows the original hinge to maintain rotation functionality while the added mount provides enhanced load support capacity for exercise equipment.
Solution Approach 2:
The invention merges the original hinge assembly with an additional mount structure that has spaced-apart knuckles defining a channel. This combination creates a composite hinge system where the original hinge provides rotation while the integrated mount extends the load-bearing capacity to support hundreds of pounds of exercise equipment.
2Strength
If a longer hinge pin is installed to create an anchor, then load support capacity increases, but the original hinge pin must be removed and the hinge assembly modified
Solution Approach 1:
The mount is pre-configured with spaced-apart knuckles that define a channel, and adapter shims are pre-positioned between the knuckles. This preliminary arrangement allows the longer hinge pin to be simply inserted through all components in one action, transforming the hinge into an anchor without complex assembly steps.
Solution Approach 2:
Adapter shims serve as intermediary components positioned between the mount's knuckles. These shims facilitate the installation by providing a interface that allows the longer hinge pin to be inserted while accommodating the existing hinge structure, simplifying the transformation from hinge to anchor.
3Adaptability or versatility
If adapter shims are added to accommodate different hinge sizes, then versatility increases, but the device complexity increases
Solution Approach 1:
The adapter shims are designed as universal components that can accommodate different standard hinge sizes (3½ inch and 4½ inch). The shims' knuckles are configured to work with various hinge pin diameters and lengths, allowing a single mount design to serve multiple hinge configurations without requiring custom components for each size.

AI summary
A kit provides an anchor for an exercise system. The kit includes a mount having spaced-apart first and second knuckles configured (i) to span interlaced knuckles of first and second leaves of a standard hinge assembly that mounts a door in a frame in an opening, the interlaced set of knuckles defining a passageway for receiving an original hinge pin, and (ii) to define a channel having a diameter sufficient to accommodate the diameter of the hinge pin. The kit also includes a replacement hinge pin, which, when inserted into the channel and the passageway, reaches the first and second knuckles of the mount defining the channel, and transforms the mount to the anchor.
