Description

concerning bed fans.®

From the protection claims it can be seen that the invention technically belongs to appliances for household and kitchen. So to class 21, more specifically to class 21/04.

The state of the art is that there is basically no bed fan that meets the protection requirements. In this respect, the bed fan is absolutely new in its type of device - a new type of device - and therefore cannot be compared to anything.

Viewed differently: The problem underlying the invention of inadequate ventilation of bedding, as described in the protection claim, has not yet been solved - if it has been recognized at all.

The problem solved by the invention arises primarily from the fact that a conventional, natural, several-hour possibility of airing the bedding in open windows or in a sufficiently loose position for ventilation is becoming increasingly less possible,

Because the air outside the houses is not only enriched with pollutants and dirt particles in the cities,

Dbecause working people usually have to leave the house in a hurry in the morning, and the windows in order to air the bedding cannot in most cases be left wide open all day - until the working people return, Dbecause more and more people live alone - as singles - and therefore no one else can take the bedding lying in windows or in openly accessible balconies, verandas, gardens during the day - as is necessary for ventilation - from the wide-open windows or from other storage rooms, Dbecause possible criminal activities prohibit airing the bedding in wide-open windows,

Because in the rush of the morning, very few people can air their beds sufficiently every day; because the beds are therefore found musty and smelly, damp and bad-smelling when they return home,

Dbecause most bedding should not be exposed to the blazing sun or moisture, but on the other hand, insufficiently ventilated bedding wears out more quickly, becomes moldy, damp and can therefore cause economic damage, Dbecause in cramped living conditions, it is difficult or even impossible to lay out bedding in sufficient space for ventilation in most cases, Dbecause heat-insulated or soundproof windows often cannot be opened sufficiently

Because most people have too little time to deal satisfactorily with the urgently needed ventilation of bedding, because people's constant primal urge for comfort leaves little motivation to devote enough time to the adequate, absolutely very necessary ventilation of bedding without the appropriate, useful equipment

D and for many other reasons not mentioned here. <

concerning bed fans.®

The invention of the bed fan, for which protection is sought in the claims, solves the described basic problem of better ventilation of the bedding.

The invention can be implemented with little means in all conceivable designs and with the help of all
conceivable materials - an example in the drawing - commercially immediately
The invention is accessible to almost every household, as the commercial application is financially and technically simple and quick - thus extremely
inexpensive - or luxurious - in terms of color, material, shape, technical sophistication and
Style elaborate and meeting every requirement - is possible.

The bed fan is, in summary, an invention

an absolutely new device - even a new type. The bed fan solves a problem that occurs in every household. The invention can be used commercially with little resources and is available to everyone in a variety of designs and by using a variety of materials and
Forms can be used.

An embodiment of the invention is explained using the figure:

First of all, it should be noted that the device is available in all conceivable shapes and colors and all
The bed fan can be manufactured with very simple means
but also in luxury versions of various kinds. From a technical point of view, the possibilities for the bed fan are wide-ranging, for example based on simple,
natural air circulation or, for example, actively ventilated and/or based on electrical engineering and/or electronics.

The drawing shows a simple example of a particularly light
Bed fan as a simple mechanical spiral solution made of synthetic material, covered with textile, with ideal, in this case natural, air permeability and air circulation.

This model, for example, can be pushed together from the long, pulled-up form to a narrow ring and is therefore almost
to be stored inconspicuously and flat.

For this model - shown as an example - the usage is as follows:
The bedding - for example duvets, pillows, mattresses, underblankets, etc. - is
After sleeping or resting, it is placed over the bed fan and remains there for
Ventilation until the bedding is reused or until it has been sufficiently ventilated. After that, it can be - considerably reduced in size - for example - pushed under the bed
It can be partially extended to ventilate a single bedding or - when fully extended - to ventilate several beddings.

With this model, the bedding is usually above the
Bed fan.
