Device for simplified parking of a bracket system

The invention relates to a steam ironing device (1) with an ironing board (2) and a base frame (3) supporting the ironing board (2), which can be provided with two rollers (4) at the lower end, and with a steam generating device (5) which has a pressure vessel, wherein the pressure vessel has a steam line connecting it to an iron, which is connected to the steam pressure vessel via a steam line connection.

Steam ironing devices are known that consist of an ironing board, an iron and a steam generation unit. Such steam ironing devices can be folded up using the base frame, which is located under the ironing board, in order to be able to store or park them with little space required. Such a base frame mainly consists of four rods, which are connected to each other in pairs and which pairs can then be folded together crosswise in a similar way to the way scissors work. There are two basic ways of parking a steam ironing device.

One option is to carry the steam iron away. This means that you fold up the base of the steam iron and lift and/or push it into the designated parking space using human muscle power.

This is a disadvantage for elderly or frail people, as well as for weak people, because steam irons are very heavy compared to simple ironing boards.

The other option is to position wheels on, for example, two of the lower ends of the base, which help the user to roll the steam iron backwards and forwards in one direction. This eliminates the need for heavy lifting.

However, it is important to note that the wheels used only roll backwards and forwards. The parking niche is often a narrow niche in which the steam iron is parked sideways. Steam irons cannot be rolled head-on into such narrow niches and therefore have to be lifted a final bit in this possible version. Weak people often have problems with this too.

The aim of the innovation is to create a steam ironing device (1) of the type in question which is easy to handle in terms of its maneuverability during so-called parking and which is able to freely carry out rolling movements in any desired direction as soon as the steam ironing device (1) is in the folded state.

The problem is solved in the present innovation as follows. In order to avoid heavy lifting, the known option of wheels (4) at the lower end of the base frame (3) is used. However, the wheels (4) are designed in such a way that it is possible to roll them in several directions. Such wheels (4) are generally called omni-wheels (4).

These Omni-Wheels (4) are known in various versions and designs. They are wheels (4) that do not block due to friction even perpendicular to the actual rolling direction. Omni-Wheels (4) are capable of controlled movement in any possible direction. Most Omni-Wheels (4) are similar in that they use wheels (4) that are characterized by a number of roller parts that are positioned around the circumference of the wheel (4).
The devices using such Omni-Wheels (4) can move in any possible direction by rotating the wheels (4) and the roller parts in an appropriate combination.

The following describes the possible design.

This chooses the method of providing the wheel (4) with roller parts on its outer edge (circumference), the axes of which are arranged perpendicular to the axis of the main wheel in the direction of the chords of the circle represented by the main wheel. Two such omni-wheels (4) are positioned at the lower end of the base frame (3) by a steam ironing device (1) on two of the rods connected in pairs. This enables the steam ironing device (1) to be moved in any direction without great effort when folded up. Rolling away in the working state is avoided because the wheels (4) are only located at two of the four ends of the base frame (3). The other two ends are simple closed tube ends that end in a hemispherical shape, for example. The steam ironing device (1) equipped with omni-wheels (4) in this way is simply rolled into its parking niche across the original possible rolling direction and parked there.

The subject matter of the invention is explained in more detail below using an exemplary embodiment illustrated in the drawing. It shows:

Fig. 4 a steam ironing device (1) according to Fig. 1, which
is in parking position.

Figure 1 shows a commercially available steam ironing device (1) in perspective. The ironing board (2) can be seen, which, as is typical for steam ironing devices (1), is provided with a steam generation unit (5). This steam generation unit (5) is located on the underside of the ironing board (2). In addition to the steam generation unit (5), the base frame (3) of the steam ironing device (1) shown here is also positioned below the ironing board (2). The base frame (3) essentially consists of four tubular parts. Two of these are connected to each other. The wheels (4) are located on two of the four tubular parts at the lower end of the base frame (3). The other two ends of the base frame (3) are shown here as being hemispherical, for example.

Figure 2 clearly shows how the individual roller parts on the wheel can be arranged, for example. There are two different roller parts: firstly, rotational paraboloids (7) and secondly, small wheels (6), which are bulbous. Such a small bulbous wheel (6) sits centrally on each of the four roller part axes (8). With the help of spacers (9), the two rotational paraboloids (7) are arranged to the right and left of the small bulbous wheel (6). The outer silhouette of all roller parts ultimately results in the shape of a circle. This circle then describes the circumference of the actual wheel (4).

Figure 3 shows the top view of an Omni-Wheel used here, corresponding to the front view in Figure 2. The individual roller parts, the small bulbous wheels (6) and the rotation paraboloids (7), as well as the perpendicular to the

Figure 4 makes the so-called parking position a little clearer. The folded steam ironing device (1) is placed upright in a niche or in a free space against a wall. The end of the base frame (3), which is equipped with the Omni-Wheels (4), is at the lower end and thus enables the use of these Omni-Wheels (4). The steam ironing device (1) can be pushed both frontally against the wall and sideways into a niche.
