Bumper device for display racks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing impact protection devices for shelves, such as ram protection bars or bumper bars, are difficult to install and remove in cramped spatial conditions, especially when access from the sides is limited, and require disassembly of brackets which are often screwed close to the ground or in hard-to-reach places.
Innovation Solution
A modular impact protection device featuring a bullbar that can be pushed onto vertically oriented brackets, utilizing snap-in connections and a combination of metal and plastic components with a partial slit and sawtooth profile for secure attachment and damping properties, allowing for easy assembly without tools and installation in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If impact protection bars are inserted horizontally into mounting rings from the side of the shelf, then secure attachment is achieved, but installation becomes difficult in confined spaces where side access is limited
Solution Approach 1:
The patent changes the attachment direction from horizontal (side insertion) to vertical (front insertion). The mounting rings are oriented with their openings facing forward, allowing the impact protection bar to be inserted from the front of the shelf rather than from the side. This dimensional change enables installation in confined spaces where side access is restricted, while maintaining secure attachment through the vertical insertion path.
2Stability of the object's composition
If brackets are screwed close to the floor or in hard-to-reach places, then stable attachment is achieved, but mounting and dismounting requires moving the shelf or using special tools
Solution Approach 1:
The patent extracts the fastening function from the bracket-shelf connection and relocates it to the impact protection bar itself. The mounting rings are attached to the shelf at accessible heights, and the impact protection bar contains integrated fastening elements (such as snap-fit connectors or threaded sections) that engage with these rings. This allows the bar to be quickly installed or removed from the front without needing to access hard-to-reach areas or move the shelf.
Solution Approach 2:
The impact protection bar is designed with self-contained fastening features that enable tool-free or tool-minimal installation. The bar itself performs the fastening action by engaging with the mounting rings through snap-fit mechanisms, threaded sections, or cam locks that can be operated from the front. This eliminates the need for external tools or complex assembly procedures, allowing quick installation and removal by a single person.
3Reliability
If continuous impact protection is provided across adjacent racks, then comprehensive protection is achieved, but complexity of installation increases
Solution Approach 1:
The patent divides the continuous impact protection system into modular segments, with each shelf having its own independently installable impact protection bar. These segmented bars can be installed separately on each shelf using the front-insertion mounting rings, yet they form a visually continuous protective barrier when viewed from the front. The segmentation simplifies installation by allowing each segment to be handled and installed independently without coordinating multiple racks simultaneously.

AI summary
The invention relates to a crash protection device for a shelf, comprising a crash protection bar (10) and at least two brackets (12), wherein the brackets (12) have a free end (16) designed to hold the crash protection bar (10). It is proposed that the crash protection bar (10) can be attached to the free ends (16) of the brackets (12) in an insertion direction (30) extending transversely to the longitudinal direction of the crash protection bar (10).
