FR2806199A1 - Traffic direction reinforcement device has shaped metal strips arranged on axle that may be freely rotated on it and accommodated in cavity taking horizontal position - Google Patents

Abstract

A case (4) includes shaped metal strips (1) arranged on an axle (3) that may be freely accommodated in a cavity (5) so as the strips (1) may take a horizontal position. The strips (1) may easily be concealed in the case when pressed from a side of allows traffic direction. When pressed from opposite direction the strips (1) form a sharp edge of protrusions (2) acting on a tire of a vehicle.

Description

The present invention relates to a device to avoid taking <B> to </ B> against a single-direction <B> direction of travel by means of a vehicle and physically forces vehicle <B> to </ B>. > stop when needed.

The current traditional means are essentially means of signaling or deterrence that do not physically prevent the driver to commit <B> to </ B> against-sense and thus create an accident.

The device according to the invention can remedy <B> to </ B> this disadvantage.

<B> It </ B> has indeed, according to a first feature a housing (4) in which are arranged one or more axes <B> (3 </ B> on which rock and go down to the horizontal of <B> (1) </ B> <B> <B> to </ B> barrels <B> (6) </ B> and weighted <B > to </ B> what its natural position is the part (2) projecting out of height of the horizontal plane and forming a stop edge for the wheels of a vehicle traveling in the opposite direction of the direction of circulation allowed opposite way the part <B> (7) </ B> of the bielette <B> (1) </ B> represents a springboard which in reality does not have this function, the part <B> (7) </ B> sinking to the horizontal thanks to the constraint exerted by the wheel of a vehicle and in the authorized direction of the traffic.

These <B> (1) <B> <B> (1) </ B> barrels rock and sink independently to the horizontal and come nestled in their slots <B> (5), </ b> this under the constraint wheels .

 Thanks to <B> to </ B> the weighted part <B> (6) </ B> of the bielette <B> (1) </ B>, this backwardness returns to its initial projecting position as soon as the constraint caused by the wheel of a vanished vehicle.

These bielettes being all independent, the wheels of the vehicle do not embed those necessary to their passages.

<B> If the front end, or the rear or two trains of a vehicle cross one or more rows of bielettes before the immobilization, the driver opens the device by simply doing a reverse <B> </ B> the device still operating and requires no intervention after removal of the vehicle.

On the other hand, if the width of the device allows it, the latter can simultaneously stop a vehicle <B> to </ B> against direction while letting a vehicle pass in the right direction. According to particular embodiments <B>: </ B> The <B> (1) </ B> can have different shapes, profiles and projections as well as anti-slip coatings and / or colors.

Bielettes <B> (1) </ B> can be laid horizontally when the device is in use and stand up only <B> to </ B> when approaching a vehicle <B> to </ B> against sense , thanks to a contactor, a contactor or a mechanical contact nose.

Bielettes <B> (1) </ B> can be aligned or arranged in staggered rows. The accompanying drawings illustrate a mode of the invention.

Figures <B> 1 </ B> and 2 represent in profile a mode of application of the device of the invention.

Figure <B> 31 </ B> represents a top view of the device. With reference to these sketches, the device comprises a housing (4) built-in or not. This box receives one or more axes <B> (3) </ B> around which or from which rock and go into the slot provided <B> to </ B> this effect <B> (5) </ B> to the horizontal of the bielettes <B> 1). </ B>

The collapse of the <B> (1) </ B> barrels is facilitated only in the direction of movement permitted thanks to <B> at </ B> the springboard form of the <B> edge (7) </ B > the bielette.

The ridge (2) of the barrel <B> (1) </ B> represents an obstacle for the vehicle which would circulate in the opposite direction of the authorized direction.

Depending on the height and the inclination of this edge (2), the wheels of a vehicle may encounter an insurmountable obstacle or surmountable according to their speeds.

In the case of a surmountable obstacle, the ridges (2) have served as bumpers, retarders for the front wheels of a vehicle, and warning for the driver <B>; they will have the same effect for the wheels of the rear train or represent for them an obstacle become insurmountable. A second row of Bielettes <B> (1) </ B> can come <B> to </ B> in turn fulfill the same functions.

This device can be designed according to the demand as a more or less brutal stop device over a longer or shorter stop distance <B> - </ b> ce in a direction of circulation.

The widths of the barrels <B> (8) </ B> allow the use of a large number of bielettes per axis row.

These bielettes being non-integral with each other, only the bielettes necessary for the passage of the wheels tilt and sink <B>, </ B> allowing the passage of the vehicle <B> to </ B> speed slow, medium or fast so perfectly horizontal in the right direction of circulation.

A layout <B> to </ B> inside the device can be arranged to facilitate the passage of two-wheelers.

Claims (1)

<B> CLAIMS </ B> <B> 1) </ B> Device physically and progressively prohibiting access <B> to </ B> against the direction of a vehicle in a flight <B> to </ B> one-way traffic. Characterized in that it comprises a casing (4) built-in or not and in which <B> (1) </ B> barrels swing on an axis <B> (3) </ B> and sink in s 'nesting in a slot provided <B> to </ B> this effect so <B> to </ B> that the <B> (1) </ B> bielettes are perfectly horizontal. 2) Device according to claim <B> 1) </ B> characterized in that the bielettes <B> (1) </ B> tilt and sink easily when the stress is performed in the direction of the traffic and take up their initial positions, erected releasing the projection (2) of the horizontal plane and thus having a stop more or less passable in the opposite direction to the direction of the authorized circulation <B>; </ B> ce when the constraint has disappeared. <B> 3) </ B> Device according to claim <B> 1) </ B> characterized in that the bielettes are at the choice of the applicant <B>, </ B> lying horizontally or placed in projections (2) when the device is in operation. 4) Device according to claim <B> 1) </ B> characterizes with respect to the position axis <B> (3) to </ B> inside the housing (4). Can be placed in different ways horizontally transversely or diagonally. <B> 5) </ B> Device according to claim <B> 1) </ B> characterized in that the housing can contain or more axes <B> (3) </ B> provided with one or more bielettes <B> (1) </ B> aligned arranged in a staggered pattern. <B> 6) </ B> Device according to claim <B> 1) </ B> characterized in that bielettes <B> (1) </ B> can be covered all or part of a non-slip surface and / or soundproofing of different colors. <B> 7) </ B> Device according to claim <B> 1) </ B> characterized in that the shapes of bielettes and building materials may be different. <B> 8) </ B> Device according to claim <B> 1) </ B> characterized in that each bielette <B> 1) </ B> can tilt and sink independently or integrally. <B> 9) </ B> Device according to claim <B> 1) </ B> characterized in that the projection 2) may have a different shape to allow more or less brutal brutality of stopping the vehicle.
