Patent ID: 8734199

Claim:
A toy component group ( 17 ), comprising: a loading arm ( 18 ), having a free end configured to lift a load, and a connecting end ( 19 ), via which the loading arm ( 18 ) is mounted on a frame ( 20 ) of the component group ( 17 ), an activating device ( 21 ) configured to adjust a loading arm setting angle (α) and thereby to lift the free end of the loading arm ( 18 ), the loading arm setting angle (α) being an angle between the loading arm and a horizontal plane, the activating device comprising: an activating element ( 23 ), a spindle ( 22 ) mounted on the frame ( 20 ), which is in drive connection with the activating element ( 23 ) configured to rotate about a spindle axis ( 24 ), a spindle nut ( 25 ) with at least one guiding element ( 26 ), a connecting link ( 27 ) secured to the loading arm ( 18 ), one end of the connecting link is pivotally mounted on the pivot axis of the loading arm, the connecting link comprising an internal slot defined along substantially an entire length of the link between the one end and a second end of the connecting link, and said connecting link ( 27 ) cooperating with the at least one guiding element ( 26 ) of the spindle nut ( 25 ) so that the at least one guiding element is moved along the connecting link within the internal slot, wherein the connecting link ( 27 ) is configured such that a force required to move the at least one guiding element ( 26 ) is a function of the loading arm setting angle (α), and wherein the connecting link ( 27 ) has a curved configuration, so that with a given activation force of the activating element ( 23 ), a lifting force, which is exerted via the adjusting element ( 23 ) on the loading arm ( 18 ), is greater at small setting angles (α) than at larger setting angles (α).
