Two-part cassette cleaning box for bicycles with hinged housing and integrated fluid drain.

Abstract

Device for cleaning bicycle cassettes, characterized in that it consists of a housing which encloses the cassette, wherein the housing is designed in the lower area as a collection tray for dirty cleaning fluid and has a drain opening through which the fluid can flow downwards.

Description

Technical field:

[0001] The innovation concerns a device for cleaning sprocket cassettes on bicycles, in particular a protective and collecting box that is mounted around the cassette on the bicycle during the cleaning process. State of the art and problem statement:

[0002] When cleaning bicycle drive components, liquid cleaner is usually sprayed on. This mixture of oil, grease, and dirt often drips uncontrollably onto the ground, tires, or frame. This leads to workplace contamination and is environmentally problematic. Purpose of the innovation:

[0003] The innovation is based on the task of creating a device that enables clean cleaning of the bicycle cassette directly on the bicycle by collecting the dirty cleaning fluid, draining it in a controlled manner, and at the same time ensuring simple, one-handed assembly. Brief description of the drawings: • Fig. Figure 1 shows the device in the closed state. • Fig. Figure 2 shows the device in the open state. • Fig. Figure 3 shows the device in the open state in an isometric view. Solution to the problem:

[0004] This task is solved by a housing constructed according to the hinged-shell principle. The device consists of an upper part (1) and a lower part (2). These two halves are movably connected to each other on one side, preferably via a solid hinge or a pivot axis with a screw connection (3). This allows the box to be opened like a pair of pliers to guide the bicycle hub and cassette, and then closed.

[0005] On the opposite side is a locking mechanism (5) to secure the halves together. Preferably, this is designed as a snap-fit ​​system with locking lugs that engage positively when the halves are closed. The lower part (2) is shaped to serve as a collection tray in its lower area. A drain opening is located at the lowest point. A hose (4) can optionally be inserted here to direct the contaminated liquid into a separate container. Advantages: * Clean workplace and proper disposal of chemicals. * Extremely simple and precise assembly thanks to the fold-out design. * No need to remove the rear wheel. 1 top 2 Lower part with drip tray and drain opening 3 Movable connection / hinge I pivot axis (with screw connection) 4 hoses (optional) 5 Locking mechanism / latching lugs

Claims

Device for cleaning bicycle cassettes, characterized in that it consists of a housing which encloses the cassette, wherein the housing is designed in the lower area as a collection tray for dirty cleaning fluid and has a drain opening through which the fluid can flow downwards. Device according to claim 1, characterized in that the housing consists of at least two components, preferably an upper part (1) and a lower part (2), which are movably or flexibly connected to each other on one side, so that the housing halves can be opened and closed. Device according to claim 2, characterized in that the movable connection is designed as a fixed hinge connection or axis of rotation (3), in particular by a screw connection or a bolt. Device according to one of claims 2 or 3, characterized in that the housing halves (1, 2) have a locking mechanism (5) on the side opposite the movable connection in order to fix the housing to each other in the closed state. Device according to claim 4, characterized in that the locking mechanism (5) is designed as a snap-fit ​​system, in particular with locking lugs, which closes positively by simply pressing the housing halves against each other. Device according to one of the preceding claims, characterized in that a hose (4) can be connected or inserted at the drain opening in the lower part (2) in order to drain the collected cleaning fluid. Device according to one of the preceding claims, characterized in that the housing has lateral recesses to receive the bicycle axle or the wheel hub in a form-fitting manner and to enable smooth rotation of the cassette within the closed housing.
