Benefits of technology

The present invention is a system that allows users to generate energy by performing moderate exercise while in a seated position. It also allows users to perform a manual or visual task in an ergonomic position. This system can offer a solution to people who need to be able to move freely because they carry out sedentary work or because of circumstances. The invention provides people with the possibility of moving with a significant degree of intensity while they are working. It offers the opportunity to create (green) energy from movement and also allows for the opportunity of localized electrical current. The invention is a furniture item that can convert human energy into usable electrical energy.

Problems solved by technology

One adverse side-effect of this situation is that this typically implies an essentially sedentary (seated) working day.
There is a growing concern that sitting still for long periods at a time is not healthy.

example 1

The Green Table

[0187]FIG. 1 contains a schematic representation of an embodiment of the present invention, in which the item of furniture (1) comprises a seating portion (2) and a table surface (3), which are connected together. The item of furniture is further characterised by having a set of two pedals (4), which enable the user to pedal while in a sitting position, whereby the said pedals generate electrical current via a generator. This electrical current can be utilised via a plug socket (5) that can be accessed by the user in the area of the table surface.

[0188]FIG. 2 shows that the height of the seating portion (2) can be adjusted.

[0189]FIG. 3 contains a schematic representation of the item of furniture in accordance with a specific embodiment of the present invention, in which an incorporated strip of light (6) is coupled to the current generator. The intensity of the light is proportional to the strength of the generated current, with the result that the harder the user ped...

Electrical Switching between the Generator and the Plug Socket

[0193]An electrical switching system between the generator and the plug socket in accordance with a non-limiting embodiment of the present invention, as illustrated in

[0194]FIG. 7, is illustrated below.

[0195]The greatest challenge comes from the fact that the capacity delivered by the generator has a strongly variable voltage, which is in direct proportion to the pedalling speed. To be able to convert this into a constant mains voltage, the inverter must have an input voltage range that is as wide as possible. One inverter with a similarly wide range is the SM 4081 by ‘Custom PSU Design’. This has a useful voltage window of 10.6 to 30V.

[0196]Preferably the buffer that is chosen is an ultra-capacitor. An interesting example in terms of capacity / cost price in this case is a 2.5V version, supplied by ‘RS Components’, with a capacity of 150F. If the system is based on a maximum system voltage of 35V, a series switching of 14 ...

Combining Different Modules

[0204]FIG. 8 contains a schematic representation of different attangements, in which a number of items of furniture (1) according to an embodiment of the present invention are connected to each other around a single table surface (3). In this example, three, six or eight items of furniture are combined around a single table surface. In a particular embodiment of the present invention, the indicators are visible for all consumers.

[0205]FIG. 9 contains a schematic representation of how an item of furniture comprising a table surface (3) can be combined in a modular manner by means of a hole (19) in the said table surface with a second item of furniture (not having a table surface). Both items of furniture comprise a central column that fits into the hole (19) of the table surface (3).

Abstract

The application provides items of furniture having a seating portion (2), a table surface (3) and a set of two pedals (4) allowing the user to pedal from a sitting position on the seating portion, whereby this set of pedals are connected to a generator.

Description

FIELD OF THE INVENTION[0001]The present invention relates to furniture that on the one hand allows green electrical energy to be generated through human movement and to be used, and, on the other, enables the user to remain fit and to perform regular physical activity. The furniture may also allow the user's performance in terms of energy creation and movement to be automatically displayed on a display on the furniture or on an electronic device that the user carries along and eventually also forwarded to e.g. social networking sites.BACKGROUND[0002]The number of people whose occupation involves working at a computer for extended periods of time is rapidly increasing. One adverse side-effect of this situation is that this typically implies an essentially sedentary (seated) working day.[0003]Even in the evenings and during weekends, these people often relax in a seated position, for example watching television sitting down or, again, sitting in front of their computers. There is a gr...
