Definitions
- the present invention relates to the field of blocking access and more particularly the terminals anti-intrusion for vehicles.
- the object of the invention is a locking device access according to claim 1.
- the locking device access includes a retractable bollard mounted at sliding in a terminal body located below the level of the ground, between a first out-of-service position where a end of the terminal is flush with the ground level and a second in-service position where it extends by relative to ground level, a first attached cover having a central cylindrical jacket for the terminal forming a pseudo-embedding of his foot when it is in service and a second cover attached to the first with a shirt whose lower end is fitted in the upper part of the first cover in extension of the latter's shirt.
- This increases by simple way the installation height of the foot of the terminal in the body, thereby increasing impact resistance side of it.
- the second cover rests on the first cover by tubular spacers embedded by their ends in each of the covers.
- These spacers constitute side shock absorbers because, for some of them, those located "behind" the terminal in the direction of the shock, the shock tending to bend the terminal causes a compression deformation of these spacers during which they deform plastically by dissipating a large amount of energy.
- the coupling of the two covers one above the other and on the terminal body is preferably made by means of tie rods housed inside the spacers.
- the device comprising a buried body 1 in the form for example of a box substantially parallelepipedic which contains elements internal guide 2 for a cylindrical terminal 3 mounted sliding in known manner in the body 1.
- the body 1 is fitted with a first cover 4 resting on feet hollow cylindrical 5 on inner ears 6 of the body 1 arranged for example in each of its angles.
- Each leg has a cylindrical hole passage of a tie rod 7 for fixing the cover 4 to the body 1.
- this orifice has a counterbore 8 intended to receive either the head of the tie rod 7, when only a cover is used, i.e. a tubular spacer 9 when the cover 4 is surmounted a second cover 10.
- each foot is also provided with a counterbore 11 for, the if necessary, accommodate and center a tubular spacer.
- the cover 4 has a tubular jacket 12 of inside diameter equal to outside diameter of terminal 3 so that it can slide there with a minimum of play so that it is kept there as if it was embedded in the cover.
- this shirt has an inlet portion 13 inner diameter enlarged compared to the diameter of the terminal so that it can accommodate the lower part an identical tubular jacket belonging to a cover superior.
- This nesting allows to offer the terminal a longer holding length in the body of terminal and therefore a tear resistance capacity under the effect of an increased lateral shock in a terminal with two covers instead of one.
- the second cover 10 is of identical structure to that of the cover 4, with feet 5, an orifice passage of tie rod opening into upper counterbores 8 and lower 11 and a central folder 12.
- the feet 5 rest directly on the ears 6 of the terminal body. It's not going out of the frame of the invention than to also provide a counterbore in each ear 6 to accommodate a tubular spacer inserted between each foot and each ear, the length of this spacer being sufficient for the feet are moved away from the mounting ears.
- the “impact” tie rods are stressed in tension while the tie rods “in shock” or more exactly the “shock” spacers 9 are stressed in compression.
- These spacers have dimensions that have been calculated to deform plastically under compression given, so they constitute a kind of fuse that absorbs a large amount of energy under a very short stroke. This deformation may be sufficient for dissipate all the energy generated by the shock; so we have preserved the other terminal organs from deformation who would have asked for their replacement.
