Mounting piece for suction hose of a central vacuum cleaning system
First Claim
1. A mounting piece for a suction hose of a central vacuum cleaning system comprising suction piping (5) placed into floor and wall constructions of a building, said mounting piece (1) being made an integral part of a suction box (6), said suction box being rigidly connected to said suction piping (5) and comprising on the inner wall (2) of said mounting piece (1) at least one rib (3) pointing inwards from the inner walls and preventing objects that would clog said suction piping (5) from pivoting into said suction piping (5) and comprising on the inner wall (2) of said mounting piece (1) at least one rib (3) pointing inwards from the inner wall and preventing objects that would clog said suction piping (5) from getting into said suction piping (5), the surfaces of the rib or ribs that meet the flow being inclined toward the central axis of the mounting piece (1).

Abstract
This invention relates to a mounting piece for the suction hose of a central vacuum cleaning system. In order to prevent objects that could possibly clog the suction piping from getting into the piping, there is on the inner wall (2) of the mounting piece (1) at least one rib (3) pointing inwards from the inner wall which prevents objects that would clog the suction piping (5) from getting into the suction piping (5). The surface of the rib (3) or ribs (3) that meet the flow are preferably inclined towards the central axis of the mounting piece.
