FIELD: doors.
SUBSTANCE: invention relates to two-leaf doors opened inside, mostly to vehicle doors. A drive device is proposed for a two-leaf door opened inside, each leaf of which is connected to leaf movement levers rigidly fixed on a rotary rack installed in supports with bearings and having a rack rotation lever fixed on the rack and connected with thrust, which is a rod of a crank-rod mechanism (hereinafter – CRM) of a drive of the rotary rack, a crank of which is an arm of a two-arm lever fixed on an output shaft of a reciprocating-rotational motion engine (hereinafter – RRME). RRME case is fixed on a base of the device, while each arm of the two-arm lever is connected, with a ball joint (hereinafter – BJ), to the first end of thrust, the second end of which is connected to the rack rotation lever so that a right arm of the two-arm lever (hereinafter – TL) is connected, with BJ, to left thrust connected to a rotation lever of a left rotary rack, and a left arm of TL is connected, with BJ, to right thrust pivotally connected to a rotation lever of a right rotary rack. On an upper crossbeam of each leaf, there are brackets with rollers coming into guide rails. The drive has unlocking means in a closed state of the door. With the door closed in a “dead point” CRM position, left thrust is located on a lower part of the ball joint of the right arm, and right thrust is located on an upper part of the ball joint of the left arm. The base consists of a bottom, rear, front, and end walls. The rear wall of the base of the device is fixed on a body wall. The guide rail of rollers fixed on brackets of upper crossbeams of leaves is made in the bottom of the base of the device.
EFFECT: increase in safety of a drive device of a two-leaf door opened inside.
