Actuator of a combined acceleration and deceleration arrangement
In an actuator of a combined acceleration and deceleration device with an operating element which is height-adjustable along a guide element and, by means of an adjustment arrangement, relative to the guide element, the operating element comprises a support plate and at least one carrier lug which extends normal to the support plate and has a guide element accommodation opening for receiving the guide element. The adjustment arrangement has a tool receiving cavity and the support plate has elastically deformable abutment webs. The invention also resides in a sliding door comprising an acceleration and deceleration device as well as such an actuator.
1. An actuator ( 30 ) of a combined acceleration and deceleration device ( 87 ) with an operating element ( 41 ) which is height adjustable along a guide element ( 31 ) and, by an adjustment arrangement ( 61 ), relative to the guide element ( 30 ), the operating element ( 41 ) comprising a support plate ( 51 ) and at least one carrier lug ( 42 ) extending normal to the support plate ( 51 ), wherein:
the carrier lug ( 42 ) has a guide element accommodation opening ( 43 ) for receiving a guide member ( 33 ) of the guide element ( 31 ),
the adjustment arrangement ( 61 ) has a tool receiving cavity ( 66 ) facing away from the guide element ( 31 ) and
the support plate ( 31 ) has abutment webs ( 53 ) which are elastic and extend along the outside of the carrier plate ( 51 ).
