Description

TITLE: "Apparatus for the remote control of the use of a bicycle by a child" DESCRIPTION
The invention relates to an apparatus for remotely controlling the use of a bicycle by a child in order to prevent the child going too far out of the sight of the person controlling the child, in order to be able if necessary to stop it in the event of danger and perhaps help it in case of need.
The known prior art does not show how this problem can be resolved.
It is an object of the invention to solve this particular problem, with a solution that is easy to produce, technologically very reliable, of limited cost and that can also be marketed in the form of user-fitted kits for bicycles with differing characteristics and with wheels which, while obviously being intended for children's bicycles, may even be of different diameters.
To solve the above problem, the invention proposes fitting the child's bicycle with an electromagnetic device connected preferably to the rear wheel of the said bicycle, which, by means of a command generated at a distance by a remote control in the hands of the parent of other person remotely controlling the child, can act as an electromagnetic friction clutch or brake, in such a way as to be able to slow or stop the bicycle. In a more advanced version, the said electromagnetic device may be such that it can be caused, by the remote control, to also act as a motor, in order to help the child in particular situations of need. The said electromagnetic device may advantageously be a small electricity generator, for example of direct current, connected to a control interface designed to be able to communicate with a remote control through a radio receiver/transmitter and with the power supplied by an electric battery connected as a buffer store to the same generator. The battery may be of small capacity if the electricity generator is used only as an electromagnetic friction clutch or brake, whereas it may be of greater capacity if when necessary it is required to be able to power the electricity generator, which for this purpose is caused through the interface to act as a motor.
Other features of the invention, and the advantages procured thereby, will be made clearer in the course of the following description, which refers to the figures of the attached sheets of drawings, in which:
Fig. 1 is a perspective view of a child's bicycle with the present apparatus in a first form of installation on the said bicycle;
Fig. 2 is a top view of the rear wheel of the bicycle of Figure 1 with the apparatus according to the invention and shows a block diagram of the control circuit for this apparatus;
Fig. 3 is an end view of the rear wheel of a bicycle with the device in another form of installation.
In the figures, B denotes a child's bicycle in which the rear wheel R is connected kinematically to a rotating electromagnetic device 1 that is fixed to the frame T of the said bicycle and is such as to be able to act, as a minimum, as a friction clutch or as a brake. The electromagnetic device 1 is preferably an electricity generator, preferably of direct current which in a possible advanced embodiment of the invention is such as to be able to act alternatively as a motor. In the example shown in Figures 1 and 2, in order that the apparatus can be adapted to different types of bicycle, the device 1 is mounted for example laterally on a built-up structure 2, of arc shape for example, its side arms, which have joints 102 for partial opening, have slots and holes with which it can be attached to the ends of the rear wheel hub M, using the nuts which come with the kit and which in turn is provided with means 202 for attaching it to the bicycle frame T, in such a way that the said structure 2 remains firmly attached to the frame. The shaft of the device 1 is connected to a roller 3 which can be supported rotatably by the structure 2 and which has a cylindrical shape, with a generatrix that is concave in the outward direction and whose lateral surface is toothed or rough, so as to engage frictionally and in a rolling manner with the tread of the tyre of the wheel R, thus producing a positive rotary connection with the said wheel, as already taught in the prior art in certain motorized propulsion systems for bicycles. The roller 3 may be of metal or some suitable plastic material and for reasons of safety may be protected by a small housing (not shown) attached to the structure 2, the details of which may easily be devised and carried out by those skilled in the art. The apparatus according to the invention comprises a box 4 containing an electronic unit 5 which switches the operational state of the device 1 , and an electric battery 6 connected for example as a buffer store to the same device 1 (see below) and optionally served by means (not shown) for recharging it from the mains supply when the bicycle is at rest. If the device 1 is to act only as an electromagnetic friction clutch or brake, the battery 6 may be of small capacity and the box 4 may for example be mounted on the same arm of the structure 2 which carries the device 1. The box 4 also houses a radio receiver/transmitter 7 with its antenna 107: this is powered by the battery 6 and is designed to control the switching unit 5, as already described. If however the device 1 is also to act as a means of propulsion, the battery 6 will be of sufficiently large capacity and the entire box 4 may be designed for example to be attached to the rear carrier T of the bicycle, as illustrated in Figure 1. Lastly, the box 4 may house known means, operated manually and/or automatically, for economizing the battery 6 consumption. The apparatus according to the invention is completed by a radiofrequency remote control 8 comprising a small radio receiver/transmitter which is able to communicate via its antenna 108 with the unit 7 in the box 4, within a radius of action of for example about fifty metres. The remote control 8 has an electric cell 9 of its own, optionally rechargeable with the battery 6, has an LED 10 indicating whether it is working properly or not, has an acoustic warning device 11 that activates automatically when the unit 7 passes out of the range of the remote control, and has one or more channels with associated activating buttons 12, so that the apparatus can be controlled in its various modes, as discussed below. The remote control 8 may also be fitted with an ON-OFF switch (not illustrated)and/or with all those known means for economizing the cell 9 consumption.
One scenario for the apparatus described to work in is as follows: normally, the device 1 is de-energized and/or disconnected and therefore completely idle so as in no way to retard the work applied by the child on the bicycle. If the child moves too far away, it is possible to use the controls 12 of the remote control 8 to operate the device 1 as a generator and connect it to a load of suitable impedance, so that this will slow its movement and that of the bicycle, with the desired intensity, in order to slow or stop the bicycle, with of course a suitable deceleration gradient so that the child does not fall off. During this phase, the device 1 is producing current which can be used to recharge the battery 6. In another scenario, the device 1 is normally in a condition in which it generates just enough voltage and current in order, for example, to keep the battery 6 charged up and to wake up the apparatus from the standby condition in which it places itself after a defined period of non-use. The resistance which the device 1 transmits to the bicycle is minimal, comparable for example to that which a dynamo causes to a bicycle when working on the wheel to generate the current necessary to power the lights of the bicycle.
Another scenario in which the apparatus may be used involves any of the previous scenarios, with the additional possibility of activating the device 1 through one of the controls 12 on the remote control 8, in such a way that the device acts as a motor, drawing electrical energy from the battery 6 and converting it into mechanical work that contributes to the forward movement of the bicycle if, for example the child is on an uphill slope, or is in a difficult situation, or is particularly tired or for other purposes or situations of necessity.
Figure 3 illustrates another installation of the apparatus on the bicycle, in which suitable means are provided on the bicycle rear hub to connect the hub kinematically to the device 1. Keyed to one end of the rotating part M1 of the hub M, which carries the freewheel sprocket, with the drive chain A is a small sprocket 13 or equivalent means which, via a toothed belt or other means 14 is connected kinematically to a small sprocket 15 or other means keyed to the shaft of the device 1 , which is designed to be attached by its own bracket 101 to the frame T of the bicycle, optionally in such a way that if desired the auxiliary anti-fall stabilizer wheels R' can be included, as indicated in broken lines. In this version, the apparatus also has the same parts 4 to 12 as described for the version shown in Figures 1 and 2.
It will be understood that the apparatus as described, may undergo other small modifications, for example relating to the method of attachment of the device 1 to the bicycle frame or relating to the kinematic connection of the said device 1 to the bicycle wheel. In the scenario considered in Figures 1 and 2 of this account, the apparatus may be in the form of a kit, because it is easily attachable by the user himself to a bicycle of any type. Clearly, however, if the apparatus is installed on a bicycle from the start, the device 1 can be fixed to any point of the frame T and can be connected to the wheel R of the bicycle in any suitable way, for example, as in the scenario shown in Figure 3. Other variants may refer to the use of a device 1 also having tachometric functions and in the provision of means for automatically limiting the speed of the bicycle when the bicycle goes outside of defined limits which may optionally be programmable by the user.
