Definitions
- the present invention relates to anti-intrusion terminals or access control and more particularly retractable bollards.
- Retractable bollards below the ground surface generally include a terminal body buried inside which is slidably mounted vertical the terminal itself.
- the body and the terminal of the means for driving the terminal between its positions in and out of order is simply an elastic member (spring, gas spring, ...) whose effect tends to make the terminal come out of the body.
- the holding the bollard in its retracted positions or in service is provided by a lock, a pneumatic example of which or implementation is described in document EP-0 605 473.
- a motorization for example pneumatic or electric which allows the operation of the terminal, in particular remote operation, when it comes to performing access control.
- the terminal has a cover which has the function on the one hand to prohibit access to the terminal's internal space and mechanism and secondly to provide a guide and embedding jacket of the mobile part of the terminal which ensures its ability to resist a shock without prematurely "taking off”.
- the cover is generally attached by screwing on the body of the terminal and for obvious reasons of maintenance, these screws are accessible from the outside if although, maliciously, it is possible to withdraw the cover and access the internal mechanism of the terminal to put it out of use.
- the invention relates to a terminal retractable with burglar-proof locking of its cover, comprising a terminal body, a terminal mounted at sliding in the body and a cover attached to the body and having a terminal passage sleeve, the terminal body comprising a pivotally mounted journal, parallel to the sleeve, located outside of it and having a protrusion lateral engaged in a planned baffle groove on the cover next to the journal.
- the cover has a rim horizontal projecting from a peripheral polygonal skirt which just fits into the top of the buried terminal body.
- the lateral projection of the journal is formed by a finger implanted radially on the latter while the groove is delimited by two partitions external to the sleeve and parallel to its axis and by at least two partitions transverse extending between the two external partitions and each having a finger passage recess adjacent to the external partition opposite to that adjacent to the removal of the other transverse partition, the partitions transverse being distant from each other by a value at least equal to the thickness of the finger measured in parallel to the axis of the sleeve.
- the above-mentioned pin is in one piece with the locking rod that has the terminal.
- the invention allows the manufacture a single cover whatever the type (manual or motorized) of terminal implemented, of course with dimensions equal.
- a retractable bollard comprises a terminal body 1, for example a parallelepiped containing a terminal 2 and its actuation mechanism for retract it inside the body or take it out.
- a cover 3 covers the upper opening of the body 1 and has a central sleeve (or shirt) 4 in which the terminal 2 can slide.
- the body 1 supports a pin 5, that is to say a axis portion rotatably mounted in guides and support 6 and 7 belonging to the body.
- This pin is of parallel axis to that of the terminal, therefore to that of the sleeve 4 and it can be placed for example in the middle of one side of the body 1.
- the pin 5 has a lateral projection formed here by a radial finger 8 implanted in the journal while the sleeve carries on the outside two partitions 9 and 10 substantially parallel and perpendicular to its axis such as when the finger is turned towards the sleeve, these partitions interfere with it in a vertical movement of the lid.
- the cover 3 comprises a peripheral flange 11 which projects from the outside compared to a skirt 12 which is of a shape complementary to the inner section of the body to be able to fit into it.
- this skirt is interrupted and is connected to the sleeve by two partitions 13 and 14 parallel to the axis of this sleeve (and parallel to each other although this is not imperative).
- the housing they define can accommodate the journal 5, its guide 6 and the finger 8 and comprises the two horizontal partitions 9 and 10. The distance between these two partitions is at least equal to the thickness (to the diameter) of finger 8 measured in the same direction.
- Partition upper 9 has on the side of the vertical partition 13 a recess 15 whose dimension is such that when the finger 8 touches the partition 13 it no longer interferes with the partition 9 in a vertical relative movement.
- the partition 10 has a recess adjacent to partition 14 16 which authorizes the passage of finger 8 when it is at contact of the partition 14. It is understood that, between the partitions 13 and 14, the space above partition 9, the recess 15, the space between the partitions 9 and 10, the recess 16 and the space under the partition 10 form a baffle groove in which the finger can be engaged 8.
- the opening 12 is equipped with a sliding lid 18 has in the thickness of the cover against a spring 18 b, which tends to place it in its shutter opening position.
- the recall of the cover 18 constituted a hindrance to access the operating polygon 19 for operators trying to access them with makeshift means.
- FIG. 3 we find most of the elements already described with the same references.
- a gas spring 20 constitutes the terminal extraction motor outside the body 1. It it is a spring applying a permanent force on the bound upwards whose intensity slightly exceeds the weight of the terminal so that an operator can easily overcome this effort to retract manually terminal.
- the terminal carries in the lower part a bolt 21 permanently stressed by a spring 22 in the direction a rod 23 which has two notches 24 and 25 in two different levels and for example open in directions offset angularly by 90 ° from each other.
- the rod 23 can be pivoted around its longitudinal axis so that it can present either the the lower notch 24 facing the terminal therefore towards the bolt, i.e. the upper notch 25.
- the bolt 21 is shown engaged in the lower notch 24. Terminal 2 is therefore immobilized in the low position.
- Using the 17 key can rotate rod 23 counterclockwise Clockwise.
- the bolt 21 is expelled from the notch 24 and the released terminal rises under the action of spring 20.
- the bolt 21 slides by rubbing on the rod 23 and, at level of the notch 25 penetrates into it, which makes it face.
- the bollard is locked in the high position, the bolt prohibiting its descent under the effect of manual effort tending to push it down.
- the upper end of the rod 23, equipped with the finger 8, in this case constitutes the pin 5 previously described.
- FIG. 4 is a diagram illustrating this variant in which the baffle groove is carried by the pin 5 by being materialized by two radial partitions 26 and 27 similar to partitions 9 and 10 but able to pivot with the journal between two fixed stops such as 28 which limit the angular movement of the pin 5.
- a finger 29 is then carried by the sleeve 4 of the cover and the maneuvering the journal angularly displaces the baffle by report to him to ultimately allow him to reach a level located under the lower partition 27 when placing in place of the cover.

Abstract
Description
La présente invention concerne les bornes anti-intrusion ou de contrôle d'accès et plus particulièrement les bornes escamotables.The present invention relates to anti-intrusion terminals or access control and more particularly retractable bollards.
Les bornes escamotables sous la surface du sol comprennent, d'une manière générale, un corps de borne enterré à l'intérieur duquel est montée à coulissement vertical la borne proprement dite.Retractable bollards below the ground surface generally include a terminal body buried inside which is slidably mounted vertical the terminal itself.
Il est prévu entre le corps et la borne des moyens d'entraínement de la borne entre ses positions en et hors service. Dans le cas le plus simple, il s'agit simplement d'un organe élastique (ressort, vérin à gaz, ...) dont l'effet tend à faire sortir la borne hors du corps. Le maintien de la borne dans ses positions escamotée ou en service est assuré par un verrou dont un exemple pneumatique ou de réalisation est décrit dans le document EP-0 605 473. Dans d'autres types de borne il existe une motorisation par exemple pneumatique ou électrique qui permet la manoeuvre de la borne, notamment la manoeuvre à distance, lorsqu'il s'agit d'effectuer un contrôle d'accès.It is provided between the body and the terminal of the means for driving the terminal between its positions in and out of order. In the simplest case, it is simply an elastic member (spring, gas spring, ...) whose effect tends to make the terminal come out of the body. The holding the bollard in its retracted positions or in service is provided by a lock, a pneumatic example of which or implementation is described in document EP-0 605 473. In other types of bollards there is a motorization for example pneumatic or electric which allows the operation of the terminal, in particular remote operation, when it comes to performing access control.
Dans toutes les constructions, la borne possède un couvercle qui a pour fonction d'une part d'interdire l'accès à l'espace et au mécanisme internes de la borne et d'autre part de fournir une chemise de guidage et d'encastrement de de la partie mobile de la borne qui assure sa capacité à résister à un choc sans se "déchausser" prématurément.In all constructions, the terminal has a cover which has the function on the one hand to prohibit access to the terminal's internal space and mechanism and secondly to provide a guide and embedding jacket of the mobile part of the terminal which ensures its ability to resist a shock without prematurely "taking off".
Le couvercle est rapporté en général par vissage sur le corps de la borne et pour des raisons évidentes de maintenance, ces vis sont accessibles de l'extérieur si bien que, par malveillance, il est possible de retirer le couvercle et d'accéder au mécanisme interne de la borne pour la mettre hors d'usage.The cover is generally attached by screwing on the body of the terminal and for obvious reasons of maintenance, these screws are accessible from the outside if although, maliciously, it is possible to withdraw the cover and access the internal mechanism of the terminal to put it out of use.
Par la présente invention on entend remédier à cette vulnérabilité en compliquant le retrait du couvercle préalablement dépouillé de ses vis de fixation. By the present invention is meant to remedy this vulnerability by complicating the removal of the cover previously stripped of its fixing screws.
A cet effet l'invention a pour objet une borne escamotable à verrouillage anti-effraction de son couvercle, comportant un corps de borne, une borne montée à coulissement dans le corps et un couvercle rapporté sur le corps et possédant un manchon de passage de la borne, le corps de borne comprenant un tourillon monté tournant, parallèle au manchon, situé à l'extérieur de celui-ci et présentant une excroissance latérale engagée dans une rainure en chicane prévue sur le couvercle en regard du tourillon.To this end the invention relates to a terminal retractable with burglar-proof locking of its cover, comprising a terminal body, a terminal mounted at sliding in the body and a cover attached to the body and having a terminal passage sleeve, the terminal body comprising a pivotally mounted journal, parallel to the sleeve, located outside of it and having a protrusion lateral engaged in a planned baffle groove on the cover next to the journal.
En général le couvercle comporte un rebord horizontal débordant d'une jupe périphérique polygonale qui vient s'emboíter dans le sommet du corps de borne enterré.In general the cover has a rim horizontal projecting from a peripheral polygonal skirt which just fits into the top of the buried terminal body.
Lors de l'introduction du couvercle il convient de manoeuvrer en pivotement le tourillon pour dans un sens lui faire décrire une partie de la rainure puis en sens inverse pour que l'autre partie de la chicane soit parcourue. L'extraction demande la manoeuvre inverse sinon l'excroissance du tourillon s'y opposera en formant une butée à l'un des flancs de cette rainure. On comprend que la manoeuvre du tourillon doit être simultanée au soulèvement du couvercle, alors que la borne est en saillie au travers du couvercle (puisqu'elle est par hypothèse en service et que l'on veut la neutraliser de manière malveillante ou non autorisée) est une opération suffisamment malcommode pour dissuader suffisamment l'opérateur de poursuivre ou de le retarder de manière importante, le contraignant ainsi à s'exposer plus longtemps au risque d'être pris en flagrant délit.When inserting the cover it is advisable to pivot the trunnion in one direction make him describe part of the groove then in direction reverse so that the other part of the chicane is traversed. The extraction requires the reverse maneuver otherwise the protrusion of the pin will oppose it by forming a abutment at one of the sides of this groove. We understand that the trunnion maneuver must be simultaneous with the lifting of the cover, while the bollard protrudes at the across the cover (since it is assumed by service and we want to maliciously neutralize it or not authorized) is an operation sufficiently inconvenient to sufficiently deter the operator from continue or significantly delay it, the thus forcing you to expose yourself to risk for longer to be caught in the act.
Dans un mode de réalisation de l'invention l'excroissance latérale du tourillon est formée par un doigt implanté radialement sur ce dernier tandis que la rainure est délimitée par deux cloisons externes au manchon et parallèles à son axe et par au moins deux cloisons transversales s'étendant entre les deux cloisons externes et possédant chacune un embrèvement de passage du doigt adjacent à la cloison externe opposée à celle adjacente à l'embrèvement de l'autre cloison transversale, les cloisons transversales étant distantes l'une de l'autre d'une valeur égale au moins à l'épaisseur du doigt mesurée parallèlement à l'axe du manchon. Cette construction présente l'avantage d'être robuste et de réalisation simple par moulage, usinage ou en mécanosoudure.In one embodiment of the invention the lateral projection of the journal is formed by a finger implanted radially on the latter while the groove is delimited by two partitions external to the sleeve and parallel to its axis and by at least two partitions transverse extending between the two external partitions and each having a finger passage recess adjacent to the external partition opposite to that adjacent to the removal of the other transverse partition, the partitions transverse being distant from each other by a value at least equal to the thickness of the finger measured in parallel to the axis of the sleeve. This construction has the advantage to be robust and simple to produce by molding, machining or mechanical welding.
Dans le cas où la borne est à manoeuvre manuelle comme dans le document EP-0 605 473, le tourillon susdit est en une seule pièce ave la tige de verrouillage que comporte la borne.In the case where the terminal is manually operated as in document EP-0 605 473, the above-mentioned pin is in one piece with the locking rod that has the terminal.
On remarquera que l'invention permet la fabrication d'un couvercle unique quel que soit le type (manuel ou motorisé) de borne mis en oeuvre, bien entendu à dimensions égales.It will be noted that the invention allows the manufacture a single cover whatever the type (manual or motorized) of terminal implemented, of course with dimensions equal.
D'autres caractéristiques et avantages de l'invention ressortiront de la description donnée ci-après à titre d'exemple purement indicatif.Other characteristics and advantages of the invention will emerge from the description given below at purely indicative example.

De manière connue une borne escamotable comporte
un corps de borne 1, par exemple parallélépipédique
contenant une borne 2 et son mécanisme d'actionnement pour
l'escamoter à l'intérieur du corps ou l'en faire sortir. Un
couvercle 3 coiffe l'ouverture supérieure du corps 1 et
possède un manchon (ou chemise) central 4 dans lequel la
borne 2 peut coulisser.In a known manner, a retractable bollard comprises

En partie supérieure, au voisinage du couvercle
le corps 1 supporte un tourillon 5, c'est-à-dire une
portion d'axe montée tournante dans des guide et support 6
et 7 appartenant au corps. Ce tourillon est d'axe parallèle
à celui de la borne, donc à celui du manchon 4 et il peut
être disposé par exemple au milieu d'un côté du corps 1. Le
tourillon 5 possède une excroissance latérale formée ici
par un doigt radial 8 implanté dans le tourillon tandis que
le manchon porte à l'extérieur deux cloisons 9 et 10
sensiblement parallèles et perpendiculaires à son axe
telles que lorsque le doigt est tourné vers le manchon, ces
cloisons interfèrent avec lui dans un mouvement vertical du
couvercle.In the upper part, near the cover

De manière plus précise, le couvercle 3 comporte
un rebord 11 périphérique qui est en saillie extérieure par
rapport à une jupe 12 qui est d'une forme complémentaire à
la section intérieure du corps pour pouvoir s'y emboíter.
A l'endroit correspondant à la position du tourillon 5,
cette jupe est interrompue et est reliée au manchon par
deux cloisons 13 et 14 parallèles à l'axe de ce manchon (et
parallèles entre elles bien que ce ne soit pas impératif).
Le logement qu'elles définissent peut accommoder le tourillon
5, son guide 6 et le doigt 8 et comporte les deux
cloisons horizontales 9 et 10. La distance séparant ces
deux cloisons est au moins égale à l'épaisseur (au diamètre)
du doigt 8 mesuré dans la même direction. La cloison
supérieure 9 possède du côté de la cloison verticale 13 un
embrèvement 15 dont la dimension est telle que lorsque le
doigt 8 touche la cloison 13 il n'interfère plus avec la
cloison 9 dans un mouvement relatif vertical. De même la
cloison 10 possède adjacent à la cloison 14 un embrèvement
16 qui autorise le passage du doigt 8 lorsqu'il est au
contact de la cloison 14. On comprend que, entre les
cloisons 13 et 14, l'espace au-dessus de la cloison 9,
l'embrèvement 15, l'espace entre les cloisons 9 et 10,
l'embrèvement 16 et l'espace sous la cloison 10 forment une
rainure en chicane dans laquelle peut être engagé le doigt 8. More precisely, the

3, le doigt 8 étant tourné vers le manchon 4, il se produit
une butée entre le doigt 8 et la face inférieure de la
cloison 10. Pour passer la cloison, on tourne le tourillon
du côté de la cloison 14 et le doigt traverse l'embrèvement
16. La cloison 9 y prend appui et par rotation inverse du
tourillon on amène le doigt sous l'embrèvement 15. Le
couvercle peut alors être totalement emboíté et son rebord
11 prendre appui sur le corps 1. Le doigt 8 est alors
orienté vers la cloison 14 et forme un obstacle au mouvement
vertical de la cloison 9 donc du couvercle.When the
Le retrait du couvercle 3 ne peut s'opérer que
par une manoeuvre inverse du tourillon 5. On notera que
cette manoeuvre est réalisée au moyen d'une clé 17 qui
traverse une ouverture 18 du couvercle, équipée par exemple
d'un opercule amovible, pour venir en prise avec un
polygone de manoeuvre 19 formant extrémité du tourillon 5.The removal of the
L'ouverture 12 est équipée d'un opercule 18a
coulissant dans l'épaisseur du couvercle à l'encontre d'un
ressort 18b qui tend à le placer dans sa position d'obturation
de l'ouverture. Le rappel de l'opercule 18a constitue
une gêne à l'accès du polygone de manoeuvre 19 pour des
opérateurs tentant d'y accéder avec des moyens de fortune.The opening 12 is equipped with a
A la figure 3 on retrouve la plupart des éléments
déjà décrits avec les mêmes références. Cette figure
illustre l'application de l'invention à une borne à
manoeuvre manuelle dans laquelle un vérin à gaz 20 constitue
le moteur d'extraction de la borne hors du corps 1. Il
s'agit d'un ressort appliquant un effort permanent sur la
borne vers le haut dont l'intensité excède légèrement le
poids de la borne de manière qu'un opérateur puisse
facilement vaincre cet effort pour escamoter manuellement
la borne.In Figure 3 we find most of the elements
already described with the same references. This figure
illustrates the application of the invention to a terminal at
manual operation in which a
La borne porte en partie inférieure un pêne 21
sollicité en permanence par un ressort 22 en direction
d'une tige 23 qui présente deux encoches 24 et 25 à deux
niveaux différents et par exemple ouvertes dans des
directions décalées angulairement de 90° l'une de l'autre.
La tige 23 peut être manoeuvrée en pivotement autour de son
axe longitudinal de sorte qu'elle puisse présenter soit la
l'encoche inférieure 24 tournée vers la borne donc vers le
pêne, soit l'encoche supérieure 25.The terminal carries in the lower part a
Dans la figure 3, le pêne 21 est représenté
engagé dans l'encoche inférieure 24. La borne 2 est donc
immobilisée en position basse. Au moyen de la clef 17 on
peut faire tourner la tige 23 dans le sens inverse des
aiguilles d'une montre. Le pêne 21 est expulsé de l'encoche
24 et la borne libérée s'élève sous l'action du ressort 20.
Le pêne 21 coulisse en frottant sur la tige 23 et, au
niveau de l'encoche 25 pénètre dans celle-ci, qui lui fait
face. La borne est verrouillée en position haute, le pêne
interdisant sa descente sous l'effet d'un effort manuel
tendant à l'enfoncer.In Figure 3, the

doigt 8, constitue dans ce cas le tourillon 5 précédemment
décrit.The upper end of the rod 23, equipped with the

de prévoir un dispositif anti-effraction constitué par
l'inversion cinématique de la coopération de la rainure en
chicane et du doigt qui y est engagé. La figure 4 est un
schéma illustrant cette variante de réalisation dans
laquelle la rainure à chicane est portée par le tourillon
5 en étant matérialisée par deux cloisons radiales 26 et 27
semblables aux cloisons 9 et 10 mais pouvant pivoter avec
le tourillon entre deux butées fixes telles que 28 qui
limitent le débattement angulaire du tourillon 5. Un doigt
29 est alors porté par le manchon 4 du couvercle et la
manoeuvre du tourillon déplace angulairement la chicane par
rapport à lui pour lui permettre en final d'atteindre un
niveau situé sous la cloison inférieure 27 lors de la mise
en place du couvercle.It is not beyond the scope of the invention that
to provide an anti-intrusion device consisting of
the kinematic reversal of the cooperation of the groove in
chicane and the finger which is engaged there. Figure 4 is a
diagram illustrating this variant in
which the baffle groove is carried by the
