The device further comprises means for inhibiting the partial opening means, able to immobilize the fixing means with respect to the drive means, at least in translation in said displacement direction, when the locking means are in their inactive position. ## Claims ### Claim 1 Device (I) for displacing a door leaf (100) with respect to a transport vehicle body, in particular of the train, tram, metro, trolley bus or bus type, said leaf being movable in a displacement movement (A1) between a closed position and an open position, with reference to an opening (104) provided in the body, this device comprising: a main body (1), fixing means (8) for fixing the leaf on the body, drive means (30), able to drive the body under the effect of motor means (106, 108), locking means (36), able to move between an active locking position in which they lock the drive means with respect to the body, in the closed position of the leaf, and an inactive release position, in which they allow displacement of the drive means with respect to this body, partial opening means (7), able to allow a small movement of the fixing means with respect to the drive means, in the movement direction, from the closed position of the leaf, characterized in that this device further comprises means (52) for inhibiting the partial opening means (7), able to immobilize the fixing means (8) with respect to the drive means (30), at least in translation in said displacement movement (A1), when the locking means (36) are in their inactive position. ### Claim 2 (depends on 1) Device according to claim 1, characterized in that the inhibition means (52) are able to move between respectively active and inactive positions, these inhibition means being able to pass from their active position to their inactive position under the effect of the passage of the locking means (36) from their inactive position to their active position. ### Claim 3 (depends on 2) Device according to claim 2, characterized in that the inhibition means (52) are able to pass from their inactive position to their active position under the effect of the passage of the locking means (36) from their active position to their inactive position. ### Claim 4 (depends on 1) Device according to claim 1, characterized in that the locking means (36) are secured to the inhibition means (52), at least in rotation about said displacement movement. ### Claim 5 (depends on 1) Device according to claim 1, characterized in that the locking means comprise at least one roller (36), carried by an arm extending radially from said body (1). ### Claim 6 (depends on 1) Device according to claim 1, characterized in that the inhibition means comprise a ring (50) mounted coaxially with respect to the body, and an inhibition tooth (52) projecting radially with respect to said ring. ### Claim 7 (depends on 6) Device according to claim 6, characterized in that the fixing means (8) define a recess (88) for selective reception of the inhibition tooth (52). ### Claim 8 (depends on 7) Device according to claim 7, characterized in that, in the inhibition position, the inhibition tooth (52) is able to come into abutment against the walls of the recess (88), in the displacement movement. ### Claim 9 (depends on 1) Device according to claim 1, characterized in that the partial opening means comprise a sleeve (7), mounted coaxially with respect to the main body (1), this sleeve being constrained to move at least in translation with the fixing means (8) in said displacement movement. ### Claim 10 (depends on 9) Device according to claim 9, characterized in that the sleeve (7) is able to move on the principal axis of the body, with respect to the drive means (30), counter to an elastic return means (56), this elastic return means comprising in particular a compression spring (56), a first end (56′) of which bears against a stop cover (5), mounted on the main body, and a second end (56″) of which bears against the sleeve (7). ### Claim 11 (depends on 1) Door for a transport vehicle, in particular of the train, tram, metro, bus or trolley bus type, comprising a fixed frame secured to the frame of said vehicle, at least one leaf (100), and at least one displacement device (I), allowing the displacement of said leaf with respect to said fixed frame (102), the or each displacement device being in accordance with claim 1. ### Claim 12 (depends on 11) Transport vehicle, in particular of the train, tram, metro, bus or trolley bus type, comprising at least one door according to claim 11.
