DEVICE FOR CLEANING AND / OR DISINFECTING A HANDLE BAR

The invention relates to a device for cleaning and / or disinfecting a handlebar made of two matching executed, joined half-shells, which are each substantially half-hollow-cylindrical and have an outer and an inner half-shell part, which parts are also joined together and one Contain cleaning and / or disinfecting liquid, with a dispensing element consisting of an absorbent material for wetting the handle bar with cleaning and / or disinfecting liquid being arranged on the inner sides of each half-shell that come into contact with the handle bar. or the suction element immersed in disinfectant liquid is supplied with the cleaning and / or disinfecting liquid.

Such a device is known, for example, from WO 2011/151212 A2. The device consists of two matching designed and firmly joined half-shells, which each consist of two half-shell parts welded to one another, which between them form the container for the cleaning or disinfecting liquid. On the inside of each half-shell that comes into contact with the handle bar, there is a dispensing element for the liquid made of an absorbent material. This dispensing element is part of a diffusion unit positioned in a slot in the half-shell, which is clamped in the slot between two seals made of plastic and has the suction element and the dispensing element. The two half-shells cannot be refilled and can only be removed from the handle bar by destroying them. After the cleaning or disinfecting liquid has been used up, the entire device must be completely replaced.

The invention is based on the object to provide a device of the type mentioned available, which is more simply constructed and easier to manufacture than the known device and is designed such that after the consumption of the cleaning and / or disinfecting liquid a Reuse of at least some components is possible.

The object is achieved according to the invention in that the cleaning and / or disinfecting liquid is introduced into a receiving space formed between the outside of the inner half-shell part and a liquid-tight plastic film tightly attached to the outside of the inner half-shell part.

In the device according to the invention, it is therefore no longer necessary to weld the two half-shell parts to one another, since the receptacle for the cleaning and / or disinfecting liquid is located on one of the half-shell parts. As a result, the construction and manufacture of the device can be simplified compared to the known ones, since the two half-shell parts no longer have to be connected in a liquid-tight manner.

In the preferred embodiment of the device according to the invention, the two half-shell parts and also the two half-shells can be connected to one another in a releasable and non-destructive manner when released. This measure makes it possible, after the cleaning and / or disinfecting liquid has been used up, to replace only that half-shell part which contains the cleaning or disinfecting liquid.

In order to provide the largest possible volume for the cleaning and / or disinfecting liquid available, according to a preferred embodiment of the invention, the plastic film is attached along the outer circumference of the inner half-shell part. It is further advantageous if the plastic film is attached to edge parts which protrude from the half-shell part and surround it. Such edge parts can be provided in a simple manner with a narrow surface completely surrounding the half-shell part, on which the plastic film is attached, according to a further feature of the invention, preferably by gluing or heat sealing.

An embodiment of the device according to the invention is particularly advantageous in which on

inner half-shell part transversely to the extension of the handle bar, at least one slot is formed, which is covered on the inside of the half-shell part by a multilayered laminate strip adhering to the side of the slot, the layers of which include the delivery element and a layer acting as a diffusion barrier. The laminate strip can advantageously be punched out of a larger-area laminate which can be produced in a simple manner.

Another measure that contributes to a simple and compact design and simple manufacture of the device according to the invention is that the suction element is attached to the side of the slot on the laminate strip accessible from the outside of the inner half-shell part.

In order to attach the laminate strip on the inner half-shell part and the suction element on the laminate strip in a particularly simple and convenient manner, the laminate strip according to the invention has two additional layers of adhesive, one of which is between the delivery element and the layer acting as a diffusion barrier and the second located on the outside of the layer acting as a diffusion barrier. In order to ensure that the cleaning and / or disinfecting liquid seeps through from the suction element to the delivery element through the adhesive layers, these are made from an adhesive that is permeable to liquids or they are perforated afterwards.

The suction element, the dispensing element and the layer acting as a diffusion barrier are preferably made of corresponding plastic nonwovens, for example made of polyethylene or polypropylene.

When operating the device on a handle bar, as far as possible, no liquid should get onto the areas of the handle bar located outside the device. For this purpose, it is provided according to the invention that on the inside of the inner half-shell part, preferably at the end faces, plastic seals are attached which run parallel to the slot and are in particular provided with at least one wiper lip that extends continuously.

It should be possible to fill the receiving space with cleaning and / or disinfecting liquid in the simplest possible way. A measure according to the invention provided in this regard consists in that at least one opening is formed on the inner half-shell part which is covered and / or closed with a plastic element made of a material that seals itself after a perforation. A needle or the like, via which the receiving space is filled, can easily be pierced through this plastic element. The material of the plastic element closes by itself immediately after removing the needle.

According to a further feature of the invention, a flat depression can be formed over a large area on the outside of the outer half-shell part, in which a transparent viewing window can be detachably inserted. Underneath the viewing window, any designed, in particular printed, elements can be used interchangeably. Alternatively, instead of a transparent viewing window, an element made for example of plastic and suitably adapted to the recess and preferably printed can be used.

The outer half-shell part is advantageously designed such that the transparent viewing window inserted into the shallow depression or the element inserted into the shallow depression can only be removed from the inside of the outer half-shell part.

For the releasable connection of the two half-shells and the two half-shell parts formed snap elements such as snap hooks, projections, depressions, undercuts for snap hooks and the like can be formed on these parts.

The length of the device along the handle bar is preferably 1.3 to 3 times its largest outer diameter. The device is designed such that it is of

Hand can be easily grasped to move along the handlebar. Their outside diameter is therefore, for example, 3 to 4 cm.

[0018] Further features, advantages and details of the invention will now be described in more detail with reference to the drawing which shows an embodiment of the invention.

The disinfection device shown in the figures is intended for the disinfection and / or cleaning of handle bars, in particular handle bars of shopping carts, luggage trolleys, handle bars in public transport and the like.

Fig. 1 shows a positioned on a handle bar 1 device 2, which is displaceable along the handle bar 1 and thereby cleans and / or disinfects the surface of the handle bar 1. The device 2, which is designed on the outside as an elongated cylinder, is designed like a hollow cylinder on the inside and is composed of two identically designed half-shells 3 by “halving” along a plane encompassing the cylinder axis. The largest outer diameter D of the device 2 is smaller than the length L of the device 2 along the handle bar 1, in particular the length L of the device is 1.3 to 3 times the outer diameter D. One of the half-shells 3 is described in detail below. The half-shell 3 is assembled from an outer half-shell part 4 and an inner half-shell part 5, the parts 4, 5 being largely designed as cylinder jacket halves and being plastic parts produced by injection molding. The outer half-shell part 4 (FIG. 4) has bead-like edges on the end faces and slightly raised edges 6a, 6b on the long sides, the inner diameter of the end face edges 6a being adapted to the diameter of the respective handle bar 1. On the outside of the outer half-shell part 4, the edges 6a, 6b encircle a shallow depression 6c extending over the majority of their outer surface. An, for example, transparent element 7 (FIG. 2), in particular a viewing window, can be inserted into this recess 6c, so that foils, labels and the like labeled can be positioned underneath this element 7. The element 7 can also be printed. The detachable arrangement of the element 7 by means of snap elements takes place in particular in such a way that it can only be removed from the inside of the outer half-shell part 4. Snap hooks 22 and centering elements 23 on the inside of the longitudinal edges of the outer half-shell part 4 allow a detachable assembly with the inner half-shell part 5.

The inner half-shell part 5 (FIG. 6) is provided on its end faces with a semicircular curved edge part 8 protruding toward the outside. Narrow edge surfaces 8a run along the upper sides of the edge parts 8. On the longitudinal sides of the inner half-shell part 5, edge parts 9 are formed, along which further narrow ones to the outside of the part 5

Edge surfaces 9a run. The edge surfaces 9a, together with the edge surfaces 8a, form a welding edge that runs continuously around the outside of the inner half-shell part 5, as will be described below. On the outer longitudinal sides 9b of the edge parts 9, projections 22a and 23a which interact with the snap hooks 22 and centering elements 23 of the outer half-shell part are formed.

The diameter of the inner half-shell part 5 on its inside is adapted to the outside diameter of the handle bar 1.

In the middle of the inner half-shell part 5, a slot 10 running from edge part 9 to edge part 9, which in particular has a width of 3 mm to 6 mm, is formed transversely to its longitudinal extent. Arch-shaped reinforcing ribs 10a are formed on both sides of the slot 10. In addition to the ribs 10a, a rectangular opening 10b, for example, locally penetrates the half-shell part 5. The slot 10 is covered on the inside of the inner half-shell part 5 with a laminate strip 11 (FIGS. 8, 9). The laminate strip 11 is composed of several layers, which are shown in FIG. The innermost layer is a dispensing element 12, which consists of a material that is absorbent for liquids, for example felt or a fleece. The delivery element 12 is connected by means of an adhesive layer 13 to a further layer 14 which forms a diffusion barrier and consists for example of a suitable fleece. The layer 14 allows liquid through in the direction of the dispensing element 12, but prevents the liquid from flowing back. The width of the layer 14 preferably corresponds to the width of the release element 12. A further adhesive layer 15 is applied to the outside of the layer 14. The layers 13 and 15 are double-sided adhesive layers, which either consist of adhesives that are permeable to alcohol and water or are subsequently perforated to ensure permeability. By means of the adhesive layer 15, the laminate strip 11 is glued via the slot 10 to the inside of the inner half-shell part 5 to the side of the slot 10. From the outside of the inner half-shell part 5, an arc-shaped suction element 16 (FIG. 10), in particular a fleece which is punched out of polyethylene, for example, is glued onto the adhesive layer 15. The suction element 16 has a high storage capacity for liquid.

Are on the inner surface of the inner half-shell part 5, preferably near the end faces, seals 17, in particular made of plastic, attached transversely to the longitudinal extent of the part 5, in particular by an injection molding process (Fig. 8). Each seal 17 is also provided along its extension with at least one wiper lip 17a, which serves as a wiper element. The openings 10b are closed on the outside, for example, by plastic elements 21, which are also attached in particular by an injection molding process. These plastic elements 21 consist of a material which seals itself after a perforation.

To complete the half-shell 3, a liquid-tight plastic film 18 (FIG. 11) is tightly attached to the outside of the inner half-shell part 5 along the peripheral edge surfaces 8a, 9a by heat sealing or gluing. In this way, a cavity for introducing a cleaning and / or disinfecting liquid is created between the welded plastic film 18 and the outside of the inner half-shell part 5. This liquid is filled in by means of a needle which is introduced into the cavity through one of the plastic elements 21 and the inner half-shell part 5. The cavity can be vented during filling via a tube or the like, which in particular is introduced into the cavity through the other plastic element 21.

The filling can take place before or after the joining of the inner half-shell part 5 with the outer half-shell part 4. The parts 4 and 5 are releasably joined by snap connections, for example snap hooks 20 are formed on the opposite longitudinal sides of the inner and outer half-shell parts 5, 4, each at the end face inside, which snap into place on the other part 4, 5. The snap hooks 20 can be bent and thereby loosened by means of a tool.

To protect the dispensing element 12, a polypropylene or polyethylene film that can be peeled off by means of a tab can be placed on the dispensing element before the two half-shells 3 are delivered.

ment to be applied adhesive.

To use the device 2, the two half-shells 3 are positioned on the handle bar 1 and joined together. The two half-shells 3 are also joined together in a detachable manner by means of corresponding snap connections. For this purpose, the two half-shells 3, as shown in FIG. 3, can be provided with snap hooks 20 which detachably snap into place on the second half-shell 3. During operation of the device, the suction element 16 soaked with cleaning and / or disinfecting liquid releases liquid through the adhesive layers 13 and 15 and the diffusion barrier 14 onto the dispensing element 12. If the device is in an immobile position, the seals 17 prevent evaporation of liquid. When the device 2 is displaced along the handlebar 1, the seals 17 prevent liquid from escaping from the device 2 to the side.

When the liquid is used up, the two half-shells 3 are separated from one another in a non-destructive manner. The two half-shell parts 4, 5 are also separated from one another in a non-destructive manner and the inner half-shell part 5 can be exchanged for a new one filled with cleaning and / or disinfecting liquid.

The slot 10 can also be attached eccentrically on the inner half-shell part and it is also possible to provide more than one slot 10 and, accordingly, several delivery and suction elements. The seals can also be attached elsewhere on the inside of the inner half-shell part. In principle, it is also possible to firmly connect the two half-shell parts 4, 5 and / or the two half-shells 3 to one another, for example by welding or by means of snap elements that cannot be detached non-destructively. In this case, too, essential advantages of the device according to the invention, such as simple construction, simple production, problem-free and simple filling, are retained.
