Description

[0001] The invention relates to a washing and cleaning system with a conveyor rail and with clothes hangers that can be moved along the conveyor rail and that receive the clothing and laundry items to be treated, and which have a sliding hook resting on the conveyor rail with a circular arc-shaped hook body bent from a steel wire.

[0002] For industrial cleaning, the garments and linens to be treated are hung on hangers and conveyed through the washing and cleaning systems. For this purpose, the hangers are equipped with a sliding bar that rests on the conveyor rails with a circular hook made of steel wire, guiding the hanger from above on both sides. Since deposits accumulate on the conveyor rails over time, there is a risk that the sliding bar hooks of the hangers will partially dislodge these deposits and soil the garments and linens on the hangers. To prevent this risk of contamination, the conveyor rails must be properly maintained and thoroughly cleaned.This also applies when clothes hangers are used whose hook bodies are equipped with a sliding coating made of plastic to reduce the sliding resistance of the clothes hangers during their conveying along the conveyor rail.

[0003] The invention is therefore based on the objective of taking precautions to counteract the risk of contamination of the items being cleaned by shearable deposits on the conveyor rail without requiring special maintenance.

[0004] Starting from a washing and cleaning system of the type described above, the invention solves the problem by providing that the hook body of at least a number of clothes hangers has a cleaning coating in the form of a felt strip projecting radially inwards along its inner arc, which is attached to a cylindrical flattening on the inside of the arc of the hook body, which has a round cross-section.

[0005] A felt strip, used as a cleaning pad and pressed against the sliding surfaces of the conveyor rail by the weight of the clothes hanger, provides a simple way to prevent the formation of deposits on the conveyor rail that could contaminate clothing and laundry. This is achieved by repeatedly passing a sliding hook, distributed across a sufficient number of clothes hangers according to the invention, over the conveyor rail, keeping it free of deposits without disrupting or interrupting the operation of the washing and cleaning systems. Even cleaning already soiled conveyor rails requires only one pass of a sufficient number of clothes hangers whose sliding hooks are equipped with cleaning pads. In this case, the clothes hangers can also be weighted to remove any deposits from the conveyor rail.Unlike plastic sliding pads, cleaning pads made of felt strips can surprisingly keep the sliding surfaces of the conveyor rail free of deposits.

[0006] An adhesive bond is recommended for attaching the felt strips, although this is not mandatory. To ensure full contact of the felt strips with the hook body under simple design conditions, the hook body, which has a round cross-section, features a cylindrical flattening on the inside of the arc to accommodate the cleaning pad, thus preventing creases from forming in the area of ​​the felt strips.

[0007] To allow for easy use of sliding hooks with different clothes hangers, the hook body can be equipped with a coupling attachment for a detachable connection to the clothes hangers. For this purpose, the coupling attachment can be provided with an angled locking arm that engages in a corresponding locking recess in the head plate of the clothes hanger.

[0008] Instead of the angled locking arm, the coupling attachment can also have a locking head that engages in a locking recess.

[0009] The invention is illustrated in the drawing as an example. It shows Fig. 1 a sliding hook of a clothes hanger according to the invention in a side view, Fig. 2 these sliding hooks in a cut along line II-II of the Fig. 1 on a larger scale and Fig. 3 the sliding hook connected to a clothes hanger on a conveyor rail in a view in the direction of the conveyor rail.

[0010] According to the Fig. 1 and Fig. 2 A clothes hanger, which according to the invention can be used in an industrial washing and cleaning system, has a sliding hook with a substantially semicircular hook body 1 bent from steel wire, which is provided on the inside of the arc with a cylindrical flattening 2. This flattening forms a receptacle for a cleaning pad 3 in the form of a felt strip, which is preferably permanently bonded to the flattening 2 and projects radially inwards beyond the hook body 1.

[0011] The sliding hook can be integrally connected to the clothes hanger. However, due to the wear and tear of the cleaning pad 3 associated with the use of the sliding hook, it is recommended to attach the sliding hook to the clothes hanger in a replaceable manner. This way, when the cleaning pad 3 wears down, only the sliding hook needs to be replaced, not the clothes hanger itself. For this purpose, the sliding hook can have a hook shank 4 with a coupling attachment 5 for detachable connection to a clothes hanger.

[0012] According to the Fig. 3. The coupling attachment 5 can consist of an end section of the steel wire forming the hook shank 4, angled relative to the hook shank 4. To accommodate this coupling attachment 5, the clothes hanger is provided with a head plate 6, which not only secures the ends of the wire hangers 7 forming the clothes hanger, but also the coupling attachment 5, each in a receiving groove 8. The position of the wire hanger ends and the coupling attachment 5 in the receiving grooves 8 is secured by a cover 9, which is removable and attached to the head plate 6. Of course, the sliding arms can also be connected to the clothes hanger in a different, interchangeable manner.

[0013] The clothes hangers equipped with sliding hooks according to the invention are suspended on a conveyor rail 10 by their sliding hooks, just like conventional clothes hangers, as is done in the Fig.As indicated in Figure 3, the sliding hook rests on the guideways 11 of the conveyor rail 10 with the cleaning pad 3 and is loaded by the weight of the clothes hanger and its hanging material. During the conveying of the sliding hanger, the guideways 11 of the conveyor rail 10 are thus protected from deposits by the felt strips of the sliding hooks, which are equipped with a cleaning pad 3. This allows deposits to be removed from the guideways 11 by the felt strips of the sliding hooks before they can become a contamination hazard for the clothing and linen items conveyed along the conveyor rail 10.
