DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a retractable boundary mark, and more particularly a road boundary mark.
BACKGROUND ART
Similar boundary marks are already known and consist of a movable body which can move inside a corresponding housing or a casing whose upper side is open, from a working position wherein said body fixedly extends above the level of the open end of the housing, to a resting position wherein said body extends so that its top is approximately level with the housing open end.
It has already been disclosed in patent n.degree. 86 05310 filed by the present applicant that such boundary marks can be equipped with driving means, whether or not remote, consisting of a single acting pneumatic jack, for example, whose cylinder is connected to a pressure fluid source through a feeding pipe.
Other boundary marks are also known which are more simple and work thanks to manually driven mechanical means.
In all the aforesaid arrangements, the retractable boundary marks are designed to allow or prohibit access to a roadway or a place on public or private roads, for example.
The above-mentioned arrangements and therefore all the retractable boundary marks have the same disadvantage, namely they are dangerous because of the relief they form above the ground thereby creating an obstacle which is not always visible to someone inattentive due to its small height.
Of course, such disadvantage increases at night in places with poor or no lighting, or even during the day when the weather is bad.
Another disadvantage thereof appeared with the boundary marks which are driven by pneumatic, electric or hydraulic means equipped with remote control.
Actually, in the latter case, the boundary mark unexpectedly coming out from its housing in order to reach its working position can be dangerous for someone inattentive and thus taken aback.
At first, it seemed therefore necessary to focus the invention on the need to indicate the presence of such boundary marks both when they are coming out and when they are in their working position.
SUMMARY OF THE INVENTION
To do so, according to a first characteristic of the invention, the body of the movable boundary mark forms an integrated electric distribution point which is supplied by a source of electric power in order that at least one current consumer can work, said consumer being placed on the body of the movable boundary mark or connected to the latter thanks to a cable.
In this case, the electric consumer is a safety device placed on the body of the movable boundary mark, which makes it possible to visualize and signal it when it is moving and/or when it is in its working position.
The safety device which is inside the boundary mark comprises visual signalling means which consist of an intermittent or flashing light signals emission when it is moving towards its working position, on the one hand, and a permanent light emission when it is fixed in this position, on the other hand.
Such electric distribution point made of the movable boundary mark body, according to the invention, has many other advantages.
Indeed, these boundary marks also can be used for reserved parking spaces or for temporary or seasonal activities areas, as for example market places, spaces reserved for fun fairs or public fairs in general.
This type of event often requires the use of electric equipment such as motors, turbines etc. as well as lighting devices.
Such consumers are usually power supplied thanks to cables connecting them to distributing boxes which are often far-off. In this case, the cables are either placed on the bare ground all the way to said box, or held overhead with makeshift supports. In both cases, cables are a real danger.
The retractable boundary mark advantageously consists in an electric distribution point according to the invention, and eliminates such disadvantages, since if the consumer to be power supplied can be a safety device comprising visual signalling means as above mentioned, it also can be any other type of consumers such as: driving electric m
