Vehicle Hatch Tipping Mechanism with Internal Pivot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing internal fitting elements for vehicles with closing hatches face issues such as restricted movement due to external hinges, which complicate locking mechanisms and obstruct access when open, or use of rotation pins that lead to jamming and reduced accessibility.
Innovation Solution
An internal fitting element with a tipping closing hatch mechanism that employs pivot means with a rotation axis rearward of the cornice, allowing the hatch to fully open outside the compartment without external hinges, using fixed locking means and a guide groove for smooth, one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external hinges are used to fix the hatch to the support structure, then the hatch can be fully opened leaving the access opening completely free, but the hinges restrict the movement to simple rotation and complicate the locking mechanism structure
Solution Approach 1:
The patent removes the traditional external hinge connection and extracts the rotation function to a pivot means positioned inside the compartment. This eliminates the need for complex external locking mechanisms while maintaining full opening capability, as the hatch connects internally rather than externally.
Solution Approach 2:
Instead of fixing hinges on the external support structure, the patent inverts the approach by positioning the pivot means inside the compartment on the cornice. The hatch connects to this internal pivot point, reversing the traditional external connection approach and simplifying the overall structure.
2Ease of manufacture
If rotation pins are used to replace hinges, then the structure becomes simpler and more economic, but the hatch continues to obstruct part of the opening when opened
Solution Approach 1:
The patent positions the pivot means in a different spatial location (inside the compartment on the cornice rather than externally) and uses an arm mechanism that extends the hatch's rotation path. This dimensional repositioning allows the hatch to clear the opening completely when open, maintaining accessibility while keeping the structure simple.
3Adaptability or versatility
If rotation pins with slotted openings are used, then the hatch gains greater freedom of movement for roto-translational motion, but the hatch becomes more labile and may arrange itself obliquely causing jamming
Solution Approach 1:
The patent introduces an arm as an intermediary element between the hatch and the pivot means. This arm acts as a mediator that guides the hatch's movement along a controlled path, preventing oblique positioning and jamming while maintaining smooth roto-translational motion. The arm ensures reliable operation by mediating the interaction between the hatch and pivot mechanism.

AI summary
The invention relates to an internal fitting element for vehicles with tipping closing hatch. It includes a frame 2, which internally delimits at least one chamber 3 accessible through at least one opening 4 formed on frame 2 and delimited by a cornice 5, and at least one access hatch 6 which is arranged to at least partial to close such an opening and is connected to the frame in a tipping manner through pivot means 10 which define a rotation axis X around which the hatch can rotate to shift between a closed position and an open position. The cornice which delimits the opening defines a seat at which the hatch is arranged in the closed position. The hatch is translatable with respect to the cornice to shift between an engagement position and a release position in relation to blocking means. The rotation axis X is rearward of the cornice inside the chamber. The access hatch is mechanically connected to the pivot means by means of at least one arm 21, sized such that in the open position, the access hatch is arranged completely outside the opening.
