DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a parking prohibition device.
The reservation of a motor vehicle parking place is a subject which has already given rise to very many proposals. These proposals may be distinguished according to two main criteria.
The first criterion refers to the remote control of the device. Indeed certain devices assume a manual intervention by the user whilst others provide on the contrary a remote control.
The second criterion concerns the signalling effect or the physical opposition effect.
To a large extent the devices proposed suffice to indicate, as clearly as possible, that the driver searching for a place is asked to look somewhere else. If the impatient motorist decides to violate the signal, the constitutive characteristics of the devices concerned aim especially at the device surviving the violation.
The other group is of course constituted by devices conceived to be physically the most inviolable possible.
It being a matter of devices offering a certain physical resistance the question to be solved is mainly avoiding a violation involving damage of the unbolting mechanism. Indeed, when such is the case the device prohibits access to the place to any third party as well as to its rightful owner.
For devices providing for a remote control and a physical resistance, a second problem arises: the protection of the indispensable electronic elements as well as of the supply batteries if they are provided. Indeed, electronics and supply are confined in the case of the device which generally diminishes the resistance to crushing, in particular if the wheel of a van or of a lorry passes over the device.
Finally, according to the philosophy adopted, with or without remote control the known devices aim either at preventing at all costs any violation or protecting, as much as can be, the device, if a violation takes place. The first risk destruction or damage, the second have purely psychological dissuasive effect which diminishes in the course of time and the experience of the offenders.
As illustration of the devices proposed, we cited, for example, French patent published under No. 2124197 and Belgian patent No. 904603 with regard to purely signalling devices. Swiss patent No. 664587 illustrates a remote control signalling device provided with means for the protection of the device in case of violation. Finally, Canadian patent No. 1177299 shows manual action devices having means for absorbing unintentional impacts.
This list is not intended to be exhaustive but simply representative of the various types of known proposals.
Generally speaking, one can retain, if they are conceived to survive a violation, the known systems employed to avoid a loading by the offending vehicle and that when the vehicle enters the place reserved as well as when it leaves. Consequently the perpetrators of the violations have little to fear from their behaviour, the parts of the prohibition devices being conceived so as not to damage them. That applies quite particularly at the time of departure of the vehicle, a moment when an actual resistance of the prohibition device could lead to a lifting effect which the known devices do not resist.
The present invention aims at proposing a device permitting of remedying to a great extent the drawbacks mentioned above.
For this purpose the parking prohibition device comprises a case enclosing feeding means, a control signals receiving member which actuates a motor coupled to a shaft bearing a movable part which the action of the motor causes to pass from a substantially horizontal position to a substantially vertical position and vice-versa. It is characterised in that it comprises means allowing the forced lowering of the movable part in the event of violation and ensuring its return to the vertical position, these means being formed so that the movable part acts like a crutch lifting the offending vehicle at the time of its withdrawal without damage to the device resulting therefrom.
One example of the device according to the invention is described in the following wi
