Problems solved by technology

[0003] Disadvantages of this embodiment are the costs involved in providing the slots in the closer housing, and the adjustment between the attachment profile of the end cap and the slot of the adapter
[0004] Another disadvantage that actually exists is that there is a gap between the end cap and the closer housing cover, which depends on the tolerances and presents an unacceptable appearance
[0005] A further disadvantage is that this embodiment shows that the end cap can be removed without effort and without difficulty by a third party who causes the door closer to be destroyed

Abstract

The invention relates to a sealing plug (10) for sealing an opening (80) of a door closer housing (20) at an end face. According to the invention, a receiving portion (30) is arranged in the opening (80) of the door closer housing (20), and the sealing plug (10) has a web (45) having a gate (35), wherein when the sealing plug (10) is inserted into the opening (80), the receiving portion (30) interacts with the gate (35) in such a way that the sealing plug (10) rotates radially and the gate (35) guides the sealing plug (10), wherein the sealing plug (10) is axially fixed in a longitudinal axis (85) and the sealing plug (10) is radially fixed by at least one spring arm (50, 55), which is arranged on the sealing plug (10).

Description

technical field [0001] The invention relates to a door closer comprising a door closer housing and a sealing plug according to the preamble of claim 1 . Background technique [0002] German patent document DE 10 2007 032 838 A1 discloses an end cap with an attachment profile located on the inside which engages in a clamping manner in a groove provided in the door closer housing on the adapter. The end cap is pushed onto the front side of the adapter, wherein the attachment profile extends in the groove and holds the end cap at the housing of the door closer in a clamping manner. [0003] Disadvantages of this embodiment are the costs involved in providing the slots in the door closer housing, and the adjustment between the attachment profile of the end cap and the slot of the adapter. [0004] Another disadvantage that actually exists is that there is a gap between the end cap and the closer housing cover, which, depending on the tolerances, presents an unacceptable appear...
