"Keyboard cleaning device"

The innovation concerns a cleaning device for keyboards with a cleaning head made of an elastic material!

Keyboards, for example of computers etc., dirty

zen over time, especially if the area around the keyboard is dirty or the user of the keyboard is a smoker and the keyboards are not covered when not in use.

A dirty keyboard looks unsightly and if it is very dirty, the keyboard’s usability can suffer.

A special keyboard cleaning device is not available on this site

known and therefore people use cotton swabs, for example, which are inserted between the gaps between the keyboards to remove the dirt that has accumulated there. This removal is laborious and cumbersome and is therefore not carried out often.

The innovation is based on the task of creating a cleaning device for keyboards, especially computer keyboards, which enables particularly quick and thorough cleaning.

This problem underlying the innovation is solved by the teaching of the characterising part of the main claim.
35

In other words, a cleaning device is proposed which has a shape such that it can be inserted into the spaces between the keys of the keyboard and essentially has a shape such that, in this inserted state, it can contact the side flanges with its sides.

the keys, so that when the cleaning device is pulled through, the keys are cleaned over a large area on their sides.

Advantageous embodiments of the innovation are described in the

Subclaims explained.

An embodiment of the innovation is shown in the drawing below, where

Cleaning device from the front and

Fig. 3 shows a cleaning device between two

Keys on a keyboard.

Referring to Fig. 1, a cleaning device 1 for keyboards is shown, which essentially consists of a handle 2 and a cleaning head 3. In this embodiment

For example, the handle 2 is made of hard plastic. However, it can also be made of other suitable materials, such as wood or the like. The cleaning head 3 in this embodiment is made of felt made of pure merino wool and, among other things, from the piano

construction is known. However, the cleaning head 3 can also be made of another material that is soft at least on its outside and can therefore adapt to the contour of the respective keyboards. A particularly advantageous design is if the material of the cleaning head 3 is absorbent.

capable of absorbing a cleaning fluid to make cleaning the keyboards even more effective.

In this embodiment, the cleaning head 3 is made entirely of soft material. However, it is also

It is possible to design the core of the cleaning head 3 from a stronger, more dimensionally stable material and to design the outside around the core softer.

Referring to Fig. 2, it can be seen that the cleaning

head 3 has a conical shape in cross-section, i.e. it is narrower in its lower area than in its upper area. This makes it possible for it to be ideally adapted to the space between the keys and to enable a relatively large and therefore simple, quick cleaning

without the cleaning head 3 having to be moved back and forth several times.

Fig. 3 shows the cleaning device 1 between two keys and 5 of a keyboard, and it is clear that due to its conical shape, which is adapted to the space between keys 4 and 5, the cleaning head 3 can be inserted into the space between keys 4 and 5 in such a way that it lies against the edges of the keys over a wide area, so that a quick and more intensive cleaning is thereby made possible. Not only the sides of keys 4 and 5 are cleaned, but also the bridges 7 between keys 4 and 5, if these bridges 7 are present at all. In keyboards without these bridges 7, only the sides of the keys and the gap between the keys are cleaned. Depending on the keyboard selected

The shape and size of the cleaning device 1 can be varied.

At its upper edge, the cleaning head 3 has a reinforcing layer 6, which in this embodiment consists of

Felt reinforced with glue. This ensures that

that pressure can be exerted on the cleaning device 1 without the cleaning head 3 changing its contour in an undesirable
Dimensions changed. Of course, the reinforcement 6 can be omitted entirely if the material of the cleaning head 3 is chosen accordingly or can be replaced by other materials that are harder than the cleaning head 3 itself.
