The invention relates to a container for a hand-held device operated by means of a small electric motor, especially dry shaver, for storing the device when not in use, with a hinged one Lid.

If solar cells are to be provided to feed such hand-held devices, then this results manifold accommodation problems. In known electrical devices namely, for a solar cell supply is provided, an accommodation of the solar cells is provided directly on the device. However, this is hardly feasible with handheld devices, in particular with dry shavers. It exists namely, when arranging the solar cells on the shaver, the risk that the shaver encompassing Cover the solar cells with your hands when using the device. Also the need would Always point the device towards the sun when using it, make it very difficult to use.

On the other hand, it is known to use electrical accessories in a container for such a hand-held device, such as Transformer, rectifier, batteries, etc. to accommodate.

It is the object of the invention to overcome the difficulties of accommodating solar cells for operating Handheld devices, e.g. B. dry razors to fix.

The object is achieved in a container of the type mentioned in that the container in such a way with a known plate-shaped solar cell carrier whose dimensions are smaller than the internal dimensions of the container are provided for supplying the operating energy that the solar cell carrier can be easily adjusted to the sun by opening the lid.

By arranging the solar cells in the container, the user avoids the solar cells with the device in hand and that the shadow of the device user may the solar cells are inoperative, while the solar cell carrier arranged in the cover relies on the The sun can be easily adjusted and the solar energy can be used as effectively as possible. This is a revealing one Handling of the device enables, and at the same time the erection of separate solar cell carriers saved.

In an advantageous development of the invention, the solar cell carrier is additionally of a foldable plate to be accommodated in the container is formed. If necessary, this can be used Significantly increase power consumption.

Despite a large input power, a container for a hand-held device operated by means of a small electric motor, in particular
Dry shaver

In this case, the flat design of the container does not need to be enlarged unnecessarily.

It can also be used advantageously an accumulator battery with associated tools that can be accommodated as a separate unit in the container, e.g. B. is releasably attached therein.

Compared to a design known per se, in which an accumulator in the housing of a dry shaver is housed, there is in this way the advantage that the dry shaver is lighter and can be more handy, making use of the fact that a container anyway for the device and the solar cell carrier is available and a feed line from the container or the sun cell carrier is provided for the dry shaver; placing the accumulator in the container therefore does not entail any additional difficulties.

It is known per se to arrange solar cells on a plate-shaped carrier. These solar cell carriers but are used in a different technical area.

The invention is explained in more detail using an exemplary embodiment shown in the drawing, various embodiments which can advantageously be used are also described. It shows

F i g. 1 is a diagrammatic representation of a container with a dry shaver housed in it,

809 590/119

F i g. 2 shows a diagrammatic representation of a solar cell carrier that can be used for this.

In Fig. 1, the container itself is denoted by 1 and the lid by 2. One can see the dry shaving device 3 shown schematically in the container 1. A unit which is releasably fastened in the container 1 is denoted by 4. This unit 4 can consist of an accumulator and electrical aids, the details of which need not be mentioned here, since they are known per se. The front surface of the unit 4 is equipped with a display device, which is provided with a scale division 5, on which the charging current of the accumulator and / or its state of charge can be read. The electrical lines and the feed cord for the shaver 3 are not shown, but it can be seen from the figure that there is sufficient space for this. The solar cell carrier 6, which is shown in FIG. 2 and has a plate-like shape known per se, contains twelve silicon cells 7 which are accessible to light. It is Z. B. possible to attach these solar cells 7 over a surface of 80 cm ² and generate a power of 1.5 to 2 watts with them, which, if desired, a small motor of a shaver can be driven directly, since such small motors are already for a power of 1 Watts at a voltage of 1 volt are known. When using such a surface of the solar cell carrier 6, a charging current of 20 mA and higher can be achieved and the solar cells 7 can be connected in series or in parallel as required and in this way also charge a 2-volt accumulator.

The solar cell carrier 6 is inserted into the lid 2 of the container 1, the surfaces of the cells 7 can be arranged either on the inside or outside. In addition, in the container 1 a separate solar cell carrier plate can also be inserted, which is used to achieve larger Power can be foldable and after opening the lid 2 next to the container 1 in the Light can be laid; the electrical connections do not need to be loosened. Of the Lid 2 is hinged to the lower part of the container 1 and can be opened so that the Surfaces of the cells 7 by adjusting the lid angle and by rotating the container 1 at can point to the sun at any position of the sun. It is also possible to completely remove the bottom of the container 1 or partially to accommodate an additional cell support plate.

The cell support plate 6 can also be combined in the cover 2 with a mirror that can be used for shaving will.
