Abstract
The invention relates to an access control device (20) comprising a first housing (21), an obstacle (25) mounted to move in translation in the first housing, a second housing (23) remote (34) from the first housing and receiving an electric motor-and-gearbox unit (26), a deformable link connected to the obstacle and co-operating with the unit, and a mechanical return device for returning the obstacle towards a position projecting out from the first housing, which return device is connected to the deformable link and is arranged in the second housing.
Claims20
An access control device (20) comprising a first housing (21), an obstacle (25) mounted to move in translation in the first housing, a second housing (23) receiving an electric motor-and-gearbox unit (26), and a deformable link connected to the obstacle and co-operating with the motor gearbox unit, the device being characterized in that the second housing is spaced apart (34) from the first housing, and in that the access control device has a mechanical return device (36 to 38) for returning the obstacle towards a projecting position outside the first housing, which device is connected to the deformable link and is arranged in the second housing.
An access control device (20) comprising a first buried housing (21), a bollard (25) slidably mounted in the first housing to slide along the substantially vertical longitudinal axis (22) of the housing, a second buried housing (23), a rotary electric motor (26) fitted with a reversible speed-reducing gearbox (63) and placed in the second housing, and a deformable link (39, 40) connected to the obstacle (25) and driven by the motor-and-gearbox unit (26, 63), the access control device being characterized in that the second housing is separated from the first housing by a dissipative structure (33) serving to reduce the amount of energy of an impact that is transmitted to a second housing, and in that it includes a hollow structure (31) connecting together the respective top portions of the first and second housings and within which a portion of the deformable link can extend and move, together with a mechanical return device (36 to 38) for returning the obstacle towards a position projecting out from the first housing, the mechanical return device being connected to the deformable link and being arranged in the second housing.
