Abstract

In a draw-in arrangement with a carrier element, which is movable back and forth from a force- and/or form-locking fixed park position to an end position and a carrier which can be coupled to the carrier element, the carrier is provided with a stop projection having a stop surface area and the carrier element has an engagement projection with a push surface area for contact with the stop projection. The stop projection is provided with a carrier-side surface layer. At least one of the surface areas is provided with an elastic surface layer to prevent contact noises. The invention also resides in a sliding door arrangement with such a draw-in arrangement to prevent contact noises.

First claim

What is claimed is:

1. A draw-in arrangement ( 10 ) comprising a carrier element ( 31 ) which is movable back and forth between a fixed park position and an end position, an acceleration and deceleration device ( 20 ) with an energy store ( 81 ) for drawing the carrier element ( 31 ) toward the park position and a pneumatic cylinder-piston unit ( 61 ) for decelerating the movement of the carrier element ( 31 ) and a carrier ( 90 ) which includes a holding recess ( 95 ) for accommodating the carrier element ( 31 ) and is provided with a stop ( 91 , 92 ) facing toward the end position and with a carrier surface area ( 96 ), and the carrier element ( 31 ) has an engagement projection ( 36 ) which includes a push surface area ( 37 ) which faces away from the park position and which is contactable with the stop ( 91 , 92 ), wherein
the carrier ( 90 ) is provided with a contact layer ( 97 ) surrounding at least the carrier surface area ( 96 ),
the engagement projection ( 36 ) is provided with a carrier element-side delimiting wall layer ( 51 ) surrounding the push surface area ( 37 ),
both, the wall layer ( 51 ) and the contact layer ( 97 ), have at least a thickness of 1.5 millimeters, and
both, the wall layer ( 51 ) and the contact layer ( 97 ), have a mean elasticity modulus at room temperature of between 700 Newton/mm 2 and 1600 Newton/mm 2 .

2. The draw-in arrangement ( 10 ) according to claim 1 wherein, the elasticity modulus of the carrier element-side delimiting wall interface layer ( 51 ) is greater than the elasticity modulus of the carrier-side interface layer ( 97 ).

3. The draw-in arrangement ( 10 ) according to claim 1 , wherein the carrier element ( 31 ) is provided with a pull member ( 38 ) which is contactable with a guide lug ( 93 , 94 ) of the carrier ( 90 ).

4. The draw-in arrangement ( 10 ) according to claim 3 , wherein the carrier element ( 31 ) and the carrier ( 90 ) are engaged, when coupled, by a press fit.

5. A sliding door arrangement ( 10 ) including a draw-in arrangement according to claim 1 , wherein the acceleration and deceleration device ( 20 ) is arranged within a height-adjustable door fitting ( 5 ).
