Title
(EN) IMPROVED ACCESS CONTROL DEVICE
(FR) DISPOSITIF DE CONTRÔLE D'ACCÈS AMÉLIORÉ
Abstract
(EN) The invention relates to an access control device (20) having a first box structure (21) to be buried, which has a first height (70); an obstacle (25) mounted in a movable manner in the first box structure; a mechanical device for returning the obstacle to a position protruding from the first box structure, which has a counterweight (37) that is movable in a second box structure (23); a geared motor (26) for driving the obstacle in movement; at least one deformable link (39) connected to the obstacle and to the return device for returning the obstacle into the protruding position; the density of the counterweight is at least equal to three; the second box structure has a second height (71) less than the first height (70); and the device has means for reducing the travel of the counterweight, which comprise at least one mobile pulley (75) on which the counterweight is suspended.
(FR) L'invention concerne un dispositif (20) de contrôle d'accès comportant un premier caisson (21) à enterrer qui présente une première hauteur (70); un obstacle (25) monté mobile dans le premier caisson; un dispositif mécanique de rappel de l'obstacle vers une position saillante hors du premier caisson qui comporte un contrepoids (37) mobile dans un second caisson (23); un motoréducteur (26) pour entraîner l'obstacle en mouvement; au moins un lien déformable (39) relié à l'obstacle et au dispositif de rappel pour rappeler l'obstacle vers la position saillante; la densité du contrepoids est au moins égale à trois; le second caisson présente une seconde hauteur (71) inférieure à la première hauteur (70); et le dispositif comporte des moyens pour réduire la course du contrepoids qui comportent au moins une poulie (75) mobile à laquelle est suspendu le contrepoids.
