Definitions
- the present invention relates to a novel electric drive for rollators, preferably for conventional rollators.
- Devices of this type are mainly known in the way that needy - for example, handicapped or physically weak - persons equipped with wheels, mobile and some with numerous accessories (transport baskets or bags, umbrella or clamp for a walking stick, seat and other useful Utensils) in various designs as a continuous support to get a feeling of security when walking / running, to support and - if available - to rest on a seat on the rollator temporarily.
- Electro-powered vibrators are already known from the prior art.
- the device developed by the Fraunhofer-Gesellschaft which can fulfill a complete therapy program in its complex execution, it concerns a three-wheeled rollator, whose wheels are all equipped with an electric drive.
- the electronic control allows you to perform a wide variety of tasks, including GPS-guided traversing of paths that the patient should then walk while his health data can be monitored and tracked in a controlled manner.
- This development of which a prototype already exists, will scarcely be used because of its complexity and the associated costs.
- the present invention is based on the object to provide an electric drive for a conventional rollator, which eliminates the disadvantages mentioned above, is simple in its construction and can be used as needed.
- An electric drive for rollators of the type mentioned at the outset is characterized in that it has a load-bearing and electro-motorized tread surface (hereinafter referred to as a platform) which can be reversibly or irreversibly arranged on the rollator by means of fastening elements.
- the platform forms the invention according to the drive, which is either fixed or detachable with the rollator - for example by means of a corresponding rod construction - is connected.
- the user can put on the preferably provided with wheels platform and hold on as usual to the handles of the rollator.
- a control allows him to set the platform on or under which an electric motor is arranged in motion, whereby the rollator is pushed in the direction of travel. The user thus has the opportunity to continue standing when his running ability is exhausted or the user wants to consciously expand his radius of action.
- the mutual actuation of the hand brakes arranged on a rollator allows the entire vehicle to be steered.
- FIG. 1 The inventive electric drive 1 on a conventional rollator 2 in a perspective view;
- Fig.l shows the electric drive 1 of the invention on a conventional, mass-produced rollator 2 in a perspective view in a preferred embodiment.
- technical adjustments may be required.
- wheels 4 are provided on the platform 3 in a particularly advantageous embodiment of the electric drive 1 for their movement.
- the steerability of the electric drive 1 is crucial for the drive of the rollator 2 and therefore has special requirements with regard to its steering behavior.
- individual or all wheels 4 are advantageously designed as castors 8.
- the pivot point over which the platform 3 is connected to the rollator 2 should be as close as possible to the platform.
- guide rollers 8 are arranged at least in the front region below the platform 3, near the area in which the fastening elements 6 are flanged.
- the platform 3 could be constructed as a whole steerable itself, so that the meeting with the wheels of the rotor 2 would be completely prevented when cornering.
- the electric motor 5 is arranged even below the platform 3. With the help of selected wheels 4, the movement of the platform 3 can be realized.
- the electric motor 5 located under the platform 3 is provided with an electronic control device, which ensures a smooth and smooth starting of the platform 3.
- corresponding mechanical components known to the person skilled in the art can also be used on the electric drive 1 or the platform 3, for example hydromechanical drive elements (clutch, transmission) or the like.
- this is - as shown in Fig.l - movably connected to the rollator 2.
- the user can trigger a steering operation by alternately actuating the brakes of the rollator 2.
- the 2 shows the electric drive 1 according to the invention in the folded-up position.
- this can, when the electric drive 1 is not needed, folded up or folded onto the rollator 2.
- the rollator 2 can then be used in the usual way as a walker.
- the individual components of the electric drive 1 and the platform 3, the drive elements 5 and wheels 4 and fasteners 6 should be made of a lightweight material z. As aluminum or a solid plastic, be made. After folding up the platform 3, it is preferably locked to the rollator 2 by means of one or more fastening devices.
- the fastening elements 6 may have at least one damping device in an advantageous embodiment, for example in the form of hydraulic cylinders, springs or one or more brakes.
- the lowering and folding up of the platform 3 can preferably take place with the aid of the electric motor 5, for example via a belt 7, which can be wound on a roll.
- the drive can be done at the same time the drive as well as the folding up of the platform 3.
- the drive can be done via toothed drive belts (toothed belt 10.1 1), which run positively in toothed pulleys, preferably axially adjacent to each other Drive shaft of the electric motor 5 are arranged.
- a coupling and brake system (consisting of coupling 12, brake 14 and tension magnet 13) is provided on the device for folding / lowering the platform 3.
- the control can preferably be actuated by pressing a button, wherein the process for preventing injury can be monitored by a security system.
- a brake 14 is provided.
- the electric drive used for lowering and / or folding up is preferably also the electric motor 5.
- the electric drive 1 according to the invention for rollators is not limited in its execution to the above-mentioned preferred embodiments. Rather, a variety of design variations are possible, which make use of the solution shown even with fundamentally different type of execution.
