Height-Adjustable Exercise Bracket With Oblique Hook Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gymnastics and physical exercise devices are limited by their design for single or few training goals, requiring additional equipment and space, with height-adjustable features being difficult to manage, especially for heavier elements, and lacking versatility for different exercises and locations.
Innovation Solution
A gymnastics device with vertical rods and U-shaped holders that allow for detachable and height-adjustable attachment of exercise elements, featuring obliquely angled hook openings and bolts that alternate in function for secure positioning and easy adjustment, enabling single-user operation and reversible attachment orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional sliding brackets with hollow rectangular cross-section are used on wall-mounted bars, then the brackets can be attached to the bar, but the brackets cannot move up or down past the mounting points, limiting height adjustability
Solution Approach 1:
The bracket is divided into multiple segments including a U-shaped support element with two parallel legs, allowing the bracket to be segmented in a way that enables height adjustment while maintaining structural integrity and attachment capability to the bar.
2Strength
If bolts are inserted through aligned transverse holes in the legs and bar for fastening, then the exercise element is securely attached, but adjusting the height of heavier exercise devices requires considerable strength and skill as the transverse holes are difficult or impossible to see from the front
Solution Approach 1:
The bracket design incorporates features that extend into the depth dimension of the bar, with the U-shaped support element wrapping around the bar and the legs positioned to engage with the bar's structure from multiple angles, making the attachment and adjustment process visible and accessible from the front.
3Adaptability or versatility
If exercise elements are attached to two bars with adjustable height, then comprehensive training is enabled, but height adjustment by a single person is either impossible or extremely difficult
Solution Approach 1:
The bracket design enables self-service height adjustment through its U-shaped support element and leg configuration that allows a single user to easily attach, detach, and reposition exercise elements on one or more bars without requiring assistance from another person.
4Adaptability or versatility
If multiple gymnastic or exercise equipment are used to achieve additional training objectives, then training versatility is improved, but space requirements increase significantly
Solution Approach 1:
The bracket system provides universal functionality by enabling a single bar or set of bars to support multiple different exercise elements at various heights and positions, allowing one piece of equipment to replace multiple specialized devices and achieve diverse training objectives without requiring additional space.

AI summary
The invention relates to a gymnastic or exercise apparatus (10) with at least one vertical bar (12) having transverse bores (20) and at least one bracket (16; 96) for attaching at least one exercise element (14, 78, 88) to the bar. The bracket comprises a retaining part (40; 98) with two parallel legs (48; 100) and two bolts (44). At least two pairs of aligned hook openings (50; 106; 124) are recessed in the legs of the retaining part. The upper hook opening of each leg extends obliquely upwards towards its rounded inner end (56; 108). After the bracket is attached to the bar, the retaining part is hooked onto the upper of the two bolts, which extends through the upper pair of hook openings, and is secured with the lower bolt, which extends through a transverse bore in the bar located below it and the lower pair of hook openings.The lower hook opening of each leg runs diagonally downwards towards its rounded inner end.
