Recessed Light Holding Rail With Longitudinal Pivot Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for recessed luminaires require deep insertion and difficult handling due to the pivot axis being parallel to the transverse direction, making assembly cumbersome.
Innovation Solution
The pivot axis is configured parallel to the longitudinal direction, allowing lateral gripping and pivoting of the carriage, reducing the insertion depth and improving handling by enabling easier access to the carriage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pivot axis is configured parallel to the transverse direction (conventional design), then the carriage can pivot relative to the rail, but the insertion depth becomes large and handling becomes difficult
Solution Approach 1:
The patent inverts the conventional configuration by changing the pivot axis orientation from parallel to the transverse direction to parallel to the longitudinal direction. This inversion allows the carriage to be gripped laterally at the end of the rail projecting into the mounting opening, enabling pivoting without requiring deep insertion into the mounting opening. The installer can now access and manipulate the carriage from the front side, dramatically reducing the required insertion depth and improving handling ease.
2Reliability
If the carriage is located at the end of the rail projecting into the mounting opening to pivot around the pivot axis, then the pivot mechanism works, but the installer must reach relatively deep into the mounting opening
Solution Approach 1:
The patent inverts the conventional arrangement by repositioning the pivot axis to run parallel to the longitudinal direction instead of the transverse direction. This allows the carriage to be gripped and pivoted laterally at the accessible end of the rail, maintaining reliable pivot functionality while dramatically improving installer access and reducing the need to reach deep into the mounting opening.
Solution Approach 2:
The patent changes the dimension of operation by shifting the pivot axis orientation from transverse (requiring deep insertion along the longitudinal dimension) to longitudinal (enabling lateral manipulation in the transverse dimension at the rail end). This dimensional change allows the installer to access and pivot the carriage from the front side rather than reaching deep into the mounting opening.

AI summary
The invention relates to a holding device (12) for a mounting frame (2) of a recessed light (1), comprising a rail (13) and a slide (14) which is adjustably arranged on the rail (13) in a longitudinal direction (X), wherein the rail (13) has two guides (15) and the slide (14) has two counter-guides (16) which are coupled to the guides (15) for moving the slide (14) along the rail (13), wherein the slide (14) is in a holding position (HS) in a first longitudinal region (17) of the rail (13), in an intermediate position (ZS) is in a second longitudinal region (18) of the rail (13) and in a mounting position (MS) is in the second longitudinal region (18) and is pivoted about a pivot axis (S) to the rail (13).Simple assembly results if the pivot axis (S) extends parallel to the longitudinal direction (X), if the first guide (15a) extends from the first longitudinal area (17) to the second longitudinal area (18), while the second guide (15b) extends only in the first longitudinal area (17), if the first counter guide (16a) and the first guide (15a) are configured such that the carriage (14) can be pivoted about the pivot axis (S) relative to the rail (13) in the intermediate position (ZS), and if the second counter guide (16b) is coupled to the second guide (15b) in the holding position (HS) and is decoupled from the second guide (15b) in the intermediate position (ZS).
