Description

Technical field

[0001] The invention relates to a shelf support for attaching horizontal shelves to vertical round tubes in modular tube shelving systems, in particular a support system with a minimal number of components and flexible mounting options after assembly of the shelving system. The components are made of die-cast aluminum, are modularly combinable, and serve to provide a stable connection between the shelf and the tube structure. State of the art

[0002] Two essential system groups are known from the state of the art:

[0003] 1. Retrofittable clamping systems with a high number of components: • Round end piece made of plastic • Plastic center piece • Metal shelf brackets with integrated threads and clamping connection • Additional metal shelf support without thread • Two-part pipe clamp • Four wood screws to connect the shelf to the support bracket

[0004] These systems are elaborate and complex in design, contain four or more individual parts, and require at least two different screw lengths. Assembly takes place in several steps, is prone to errors, and results in high storage and production costs.

[0005] 2. Systems with direct integration of the shelves during assembly: • These systems use drilling aids and require drilling through the shelves. • Special tools such as drill guide attachments and drill heads are necessary • Assembly is only possible during system setup. • Retrofitting or expansion (e.g., with three or more vertical bars) is not planned. • The drilling process causes dirt and can permanently damage the shelves. • The holes must be drilled very precisely, otherwise the base cannot be pushed onto the rods. Object of the invention

[0006] The invention is based on the objective of creating a shelf support that: • The system is expandable • Features a drastically reduced number of components • Simple, quick and error-free assembly is possible • Savings in warehousing, logistics and potentially also in production • Ensures the same or greater stability with lower system complexity • No special tools (e.g., drill guide attachments and / or drill heads) are required • No drilling through the shelf is required • Can also be installed retroactively, i.e., after the pipe system has been installed • Can be mounted in any height and is infinitely adjustable • The addition of center supports (for more than two vertical tubes) allows • Opposing screw insertion with identical screws via two axially arranged screw channels allows Solution to the task

[0007] The invention is based on a modular, axially screwable system made of two die-cast aluminum parts: • Clamp A-1: ​​round end piece for combination with Clamp A-2 for attachment to a vertical tube, without its own shelf support. Clamp A-1 has two opposing screw channels with identical thread profiles. One of these screw channels faces outwards and serves as the entry point for a screw; the other faces inwards and accepts the screw of the opposing component. • Clamp A-2: Shelf support with two opposing screw channels with identical thread profiles. As with Clamp A-1, one of these channels opens outwards, the other inwards. This arrangement allows connection to Clamp A-1 or to another Clamp A-2 by screwing in two identical screws in opposite directions.

[0008] Clamp A-2 and Clamp A-1 each have two screw channels, each with an axially opposite screw channel opening facing outwards. Identical screws are inserted from both sides (in opposite directions) without requiring different screws or mirror-image components. The screw channel opening of both components must be on the same side of Clamp A-2 and Clamp A-1, regardless of whether it is the left or right side. The threads have an identical thread profile, which is why identical screws can be inserted from both sides (in opposite directions) without requiring different screws or mirror-image components. This allows the components to be combined with each other and with themselves in any configuration.

[0009] This design enables: • The combination of the components among themselves and with each other • The use of a single component (Clamp A-2) for mid and end supports • The elimination of additional special parts or clamps • The combination of components into sets with only two cast parts and a single type of screw

[0010] Example set compositions: • Pipeholder End: 1× Clamp A-1 + 1× Clamp A-2 • Pipeholder (center holder): 2× Clamp A-2 • Pipe holder ring: 2× Clamp A-1

[0011] Advantages: This construction method reduces storage and production costs as well as assembly effort, reduces sources of error during assembly and enables a flexible, expandable racking system for a wide variety of applications.
