Device for temporarily fixing a metallic airfoil to container edges

Abstract

Device for temporarily fixing a metallic carrying handle (4) to an edge (3) of a container, characterized in that the device has a holder (1) attachable to the edge (3) with an integrated permanent magnet (2), wherein the permanent magnet (2) is arranged such that its effective surface faces the carrying handle (4) and magnetically holds the carrying handle (4) in a position applied to the edge (3).

Description

Technical field

[0001] The invention relates to brackets for temporarily locking swiveling metal brackets on containers such as buckets, tubs, vats or similar transportable vessels. State of the art

[0002] Containers with insertion or locking points for carrying handles are known in the prior art. For example, DE 20 2017 004 333 U1 describes a handle fixing that requires structural elements on the container. Comparable solutions use recesses, holding points, or special handle suspensions. These approaches are regularly tied to a specific container design and cannot be readily transferred to existing containers with different designs. Object of the invention

[0003] The aim is to provide a universally retrofittable device that allows the metallic carrying handle of a container to be temporarily fixed to the edge without having to change the container geometry.

[0004] The solution should in particular: • When emptying garden, stable and construction site containers, prevent the handle from falling into the bulk material, getting caught and obstructing the flow; • Make it more difficult for animals to unintentionally grab the bar during stable operations; • should be easy to assemble and disassemble, and adaptable to different ironing board weights. Description of the invention (solution)

[0005] The problem is solved by at least one holder (1) attachable to the rim of the container, with an integrated permanent magnet (2) whose effective surface faces the metallic carrying handle (4). When the handle is placed laterally against the rim, the magnet holds the handle securely in a position favorable for emptying by magnetic attraction.

[0006] The bracket is designed as a separate component and can be retrofitted. In a preferred version ( Fig. I) It has a disc-shaped head (6) with a radial magnetic pocket, as well as a self-locking plug or snap pin (5) for fastening in a small bore (8) provided in the rim of the container (3). The pin length can be shortened after assembly.

[0007] Alternatively, the bracket can be used as a clip-on U-clamp ( Fig. III) be designed so that it can be attached to the rim without drilling.

[0008] The holding force can be adjusted to different handle weights by varying the number, size, and quality of the magnets (e.g., neodymium magnets). For typical 10-liter buckets, two holders, preferably positioned opposite each other, are usually sufficient. Advantages • Universal & retrofittable: Suitable for almost all buckets / tubs with metal handles; no structural modifications to the container are required. • Easy handling: Tool-free clip-on or simple plug-in assembly; removable. • Adaptable: Holding force scalable via number / quality of magnets; components can be manufactured in plastic or metal. • Economical & robust: No moving parts; permanent magnets enable maintenance-free operation. • Safer workflow: Hands-free, clean emptying; reduced snagging of the handle in the contents; less risk of tipping over. Brief description of the drawings Fig. Figure 1 shows a spatial representation of a preferred holder (1) with integrated magnetic part cassette (2) and plug pin (5). Fig. Figure 1A-B shows section AB through the head (6) with radially arranged magnetic pocket. Fig. Figure 2 shows a top view of a circular container rim (3) with two supports (1) mounted on the rim and the carrying handle (4). Fig. Figure 3 shows a clamping design with an attached permanent magnet.

[0009] The holder (1) consists of an injection-molded plastic head (6) with a pocket into which a flat neodymium magnet (2) is inserted by a form-fit or material-fit connection (e.g., glued / encapsulated / clamped (11)). The magnetic contact surface is flush with or slightly recessed from the outer circumferential surface of the head. A ribbed locking pin (5) is molded onto the head, which is pressed through a bore (8) in the container rim (3) and holds itself there in a self-locking position. The pin length can be shortened towards the rear. Example 2 - Clip version (Fig. 3):

[0010] A magnetic holder (8) with magnet (2) is placed on top of the edge (3) and secured via spring-loaded

[0011] Tabs (9) are fixed / clamped. This variant has the advantage that no drilling is required and is therefore also suitable for temporary use. Arrangement on the vessel (Fig. 2):

[0012] Two holders (1) are preferably symmetrically distributed around the edge (3) in the contact area of ​​the hanger. To empty the hanger, the hanger (4) is guided laterally to the edge and held by the magnets. For heavier hangers, the number of holders can be increased or higher-quality magnets can be used. Summary (Abstract)

[0013] The invention relates to a retrofittable holder (1) for the temporary fixing of a metallic carrying handle (4) to a container rim (3). A permanent magnet (2) integrated into the holder magnetically holds the handle, which is placed laterally against the rim, thus facilitating, in particular, the emptying of the container. The holder can be implemented as a plug-in or clip-on version, requires no structural modifications to the container, and the number and magnet strength can be adapted to the handle weight.
