Drive system having a linear actuator and item of furniture having such a drive system

Drive system having

• a linear actuator for transmitting a linear movement, the linear actuator including:
• a spindle,
• a nut cooperating with the spindle,
• an electric motor for driving the spindle,
• a first securing means at a first end of the linear actuator, and
• a third securing means at a second end of the linear actuator;
• a fixed frame including a second securing means and fourth securing means;
• at least one movable frame coupled to the nut in an articulated manner by means of at least one actuation rod, such that movement of the nut along the spindle causes movement of the movable frame relative to the fixed frame, wherein either (a) the nut has at least one stud and the actuation rod is provided with a corresponding recess for fitting the actuation rod onto the stud or (b) the actuation rod has at least one stud and the nut is provided with a corresponding recess for fitting the stud onto the actuation rod, wherein a securing element secures the actuation rod and stud together;
• and
• a locking element,
• wherein the linear actuator is releasable secured to the fixed frame so as to be movable between a mounted position and a dismounted position, and wherein, in the mounted position:
• the first securing means of the linear actuator engages the second securing means of the fixed frame, and
• the locking element secures the third securing means of the linear actuator to the fourth securing means of the fixed frame by selectively engaging and disengaging the third securing means and fourth securing means,
• and the first securing means, the second securing means, the third securing means, the fourth securing means, and the locking element are structured such that, upon disengaging of locking element with the third securing means and fourth securing means, displacement of the linear actuator relative to the fixed frame in a longitudinal direction of the spindle disengages the first securing means from the second securing means and thus moves the linear actuator to its dismounted position.
