BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to barriers for the protection of reserved areas against intrusion by motor vehicles.
2. Description of the Prior Art
"Reserved areas" are to be taken to mean areas for the parking of private vehicles, or so-called individual parking spaces, conferring upon their owners a right of private use, or areas for circulation intended for the sole use of pedestrians or authorized vehicles, such as pavements, avenues, alleys or lanes, for example. In such cases, protective barriers are provided to prevent access to these areas by all unauthorized vehicles. "Reserved areas" are also to be taken to mean surface areas occupied by trees, posts of the signpost type, poles carrying carrying electric cables, telephone poles, telegraph poles, pylons and the like and, in these cases, the said barriers are specially designed and located so as to prevent any damage resulting from shocks or bumps caused by machines, vehicles or others.
Thus, for example, in the case of indivual parking spaces or entries to private roads or drives, these barriers generally take the form of devices firmly anchored in the ground which are able to occupy two extreme positions, namely: an upright position and a lying position. The upright position corresponds to the position preventing access to the reserved area by any vehicle, while the lying position permits such access. These two positions are attained as a result of pivotal movements imparted to the said devices, and they can be blocked using any appropriate means so as to prevent an external event or an authorized party from modifying them. The owners of private parking spaces thus have at their disposal locking or blocking means giving them alone the ability to operate the said barriers. However, it frequently happens that these devices are subjected, deliberately or unintentionally, to shocks and that, as a result, they are damaged to the extent of becoming unusable and of having to be removed and replaced, which involves quite a substantial investment. The same applies to barriers designed for the protection of trees, posts and the like, which barriers are placed around these trees or posts so as to form obstacles preventing their damage by violent bumps or shocks.
SUMMARY OF THE INVENTION
The present invention aims to avoid these drawbacks and to enable these devices to withstand or absorb shocks without this necessarily resulting in the need to proceed to the said removal and replacement.
For this purpose, the invention provides a barrier comprising at least one vertical element pivotally mounted on a sole anchored in the ground, and characterized by the arrangement, between the said sole and the said vertical element, of an elastically deformable means having at least one spring extending between a terminal zone integral with the said sole and a zone engaging with the said element.
Such an elastically deformable means can easily be designed, on one hand to absorb any shocks or thrusts, the whole resisting passage across this element by any vehicle without the latter sustaining damage and, on the other hand, to bias the said element back to its normal protective position.
According to one possible form of embodiment suitable for barriers to protect individual parking spaces or reserved circulation areas, the said element articulated at its base consists of a post and acts against the said elastically deformable element with which it is associated when it is biassed in the direction opposite that of normal swinging towards a lowered rest position, and a means is provided for limiting the amplitude of the deflection resulting from this biassing; horizontal pin, the ends of which form pivots supported by bearings provided in a shoe or housing borne by the sole that is to be anchored in the ground, and this same base is adapted to act directly in compression upon a spring provided on the said sole when a thrusting force is exerted in the direction opposite that bringing the said post into its normal lower
