Oven Rack Latching Structure for Leak-Free Pull-Out Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Household ovens with rib-like sliding elements face challenges in providing a reliable latching mechanism without using bulky or costly space-projecting stops, especially when space is limited near the cooking chamber floor.
Innovation Solution
The implementation of convex or concave latching formations aligned vertically or horizontally with the rib-like sliding elements, which are integrated into the sliding elements or food supports, ensuring a leak-free and space-efficient latching mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spatially projecting stops or latching means are used to prevent food supports from tilting or detaching, then latching reliability is improved, but device complexity and space consumption increase
Solution Approach 1:
The latching formation is merged with the sliding element itself, integrating the latching function into the existing rib-like structure. The formation protrudes from the sliding element and engages with a corresponding recess in the food support, eliminating the need for separate stopping mechanisms while maintaining latching reliability.
Solution Approach 2:
Instead of using bulky stops throughout the cooking chamber, the invention applies localized formations only at specific positions on the sliding elements where latching is needed. These formations are precisely positioned to engage with corresponding features on the food support, providing targeted latching without unnecessary space consumption.
2Reliability
If vertically projecting formations are used on sliding elements near the cooking chamber floor, then latching function is achieved, but available space is reduced
Solution Approach 1:
The invention transitions from vertical projections to horizontal projections of the latching formation. Instead of extending vertically downward from the sliding element, the formation protrudes horizontally from the end face of the rib-like sliding element, engaging with a corresponding horizontal recess in the food support. This dimensional change preserves space near the cooking chamber floor while maintaining the latching function.
3Object-affected harmful factors
If closed formations are used in sliding elements, then cooking chamber seal is maintained, but manufacturing complexity increases
Solution Approach 1:
The latching formation is created as an integrated part of the sliding element through embossing or molding during manufacturing. This merging of the latching feature with the base sliding element structure allows the formation to be produced in one step with the main component, avoiding additional manufacturing operations while ensuring the closed design maintains the cooking chamber seal.

AI summary
The baking oven according to the invention has a cooking chamber (2) that can be closed by an oven door and into which at least one food support (11) can be inserted on sliding elements (9, 10) arranged on both sides of the cooking chamber (2), with at least one sliding element having a shaped portion (12, 14 ) is provided, in which the food support (11) provided with a corresponding reciprocal formation (13) can be latched to form a detent stop limiting the pushing-out movement of the food support (11).
