Guide Rail Quick-Fastening Between Adjacent Oven Side Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick-action fastening elements for guide rails in cooking appliances are difficult to attach food supports of the same size as the grid-like side parts, and they occupy too much space within the appliance, limiting the utilization of space for guide rails and food.
Innovation Solution
A quick-action fastening element with a unique configuration that allows for a greater deviation in rod spacing, featuring a first and second holding section connected by a connecting section, which can be angled and elastic, enabling secure attachment of guide rails between adjacent rods while optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional quick-action fastening elements are used to attach guide rails to lattice-like side parts, then the guide rails can be detachably mounted for cleaning or repositioning, but the fastening elements occupy excessive space within the cooking appliance interior, limiting the space available for guide rails and food supports
Solution Approach 1:
The quick-action fastening element is divided into two separate components: a first quick-action fastening element attached to the first rod, and a second quick-action fastening element attached to the second rod. This segmentation allows each element to be compact and minimizes the overall space required while maintaining the detachable mounting function.
Solution Approach 2:
The second quick-action fastening element is positioned within the space defined by the first holding section of the first fastening element. This nesting arrangement allows both fastening elements to coexist in a compact configuration, significantly reducing the volume occupied by the fastening system within the cooking appliance interior.
2Ease of manufacture
If conventional quick-action fastening elements are used with standard rod spacing, then the fastening mechanism is simple, but it becomes difficult or impossible to attach guide rails that support food supports of the same size as the grid-like side parts
Solution Approach 1:
The holding sections of the quick-action fastening elements are designed with elastic properties, allowing them to flex and adapt to variations in rod spacing. This dynamic capability enables the fastening mechanism to accommodate different guide rail sizes and configurations while maintaining a simple overall structure.
Solution Approach 2:
The distance between the first and second holding sections is designed to correspond to the distance between the first and second rods, with the holding sections capable of elastic deformation. This parameter flexibility allows the fastening element to adapt to different rod spacings and guide rail dimensions without requiring a completely different fastening mechanism.

Function Achieved in This Case
This configuration allows for efficient use of space between rods for attaching guide rails, supports food supports of varying sizes, and provides flexibility in positioning the fastening section, enabling secure and adaptable attachment of guide rails and additional elements.
Implementation Method 1
the connecting portion (4) has a fastening section (5) for fastening the guide rail (100), wherein the first and second holding sections (2, 3) extend from the connecting section (4) at an angle to one side between the rods of the pair of rods

AI summary
The present invention relates to a quick-fastening element for fastening a guide rail on two adjacent, horizontally running rods of a grille-like side part, said rods being arranged substantially vertically one above the other, and parallel, and being bent at an angle in their end region. In order to provide for quick fastening which can be established straightforwardly and inexpensively and by means of which the space within a cooking appliance is used to the optimum extent, the invention proposes a quick-fastening element which has a first retaining portion, which is designed for form-fitting and/or force-fitting engagement of the quick-fastening element with a first rod of the two adjacent rods, a second retaining portion, which is designed for form-fitting and/or force-fitting engagement of the quick-fastening element with a second rod of the two adjacent rods, and a connecting portion, which is arranged between the first retaining portion and the second retaining portion and connects the retaining portions, wherein the first and second retaining portions extend from the connecting portion to one side such that they can be fastened in an angled state between the rods of the pair of rods and, in the fastened state, they butt against mutually facing sides of the rods, wherein the connecting portion has a fastening portion for fastening the guide rail.
