Mounting unit and method for installing an electrical module

Abstract

A mounting unit for installing an electrical module, typically a lighting module, in a wall having an opening, comprising: a plate having an opening provided for attachment to one side of the wall W; wherein the opening in the plate is smaller than the opening in the wall; a first tubular part provided at the end thereof, along its circumference, with at least one outwardly projecting stop part; wherein the first tubular part is adapted to be clamped into the opening in the plate; a second tubular part in which the electrical module can be received.

Claims

[1] Mounting unit for installing an electrical module, typically a lighting module, in a wall having an opening, comprising: - a first tubular part (20); - a second tubular part (30) in which the electrical module can be received; wherein the first and second tubular parts (20, 30) are designed such that the second tubular part can be clamped into the first tubular part in various positions; wherein the first tubular part (20) is provided with at least one inwardly projecting, press-in positioning part (26) which is provided with a first profile (27) for defining various positions; and an outer wall (31) of the second tubular part (30) is provided with a second profile (37) which can be coupled to the first profile (27) in various positions. [2] Mounting unit according to claim 1, characterized byin that the first and second tubular parts (20, 30) are designed such that the second tubular part can be mounted in a suitable position from the various positions in the first tubular part such that the height of the second tubular part can be adjusted depending on the thickness of a plaster layer to be applied to the wall. [3] Mounting unit according to claim 1 or 2, wherein the at least one inwardly projecting depressible positioning part comprises at least two resilient positioning lips (26). [4] Mounting unit according to claim 3, wherein the at least two positioning lips are formed by providing at least two U-shaped recesses (28) in a peripheral wall (25) of the first tubular part. [5] Mounting unit according to one of claims 1-4, wherein the second profiling (37) is formed by providing a thread along an outer wall (31) of the second tubular part. [6] A mounting unit according to any one of the preceding claims, wherein the first and second tubular members are cylindrical. [7] Mounting unit according to one of the preceding claims, comprising: - a plate (10) having an opening (11) intended for attachment to one side of the wall W; the opening in the plate being smaller than the opening in the wall; - wherein the plate is connected to the first tubular part (20). [8] Mounting unit according to claim 7, wherein the plate is provided with perforations designed to cooperate with screws (40) for fixing the plate to the wall. [9] Mounting unit according to one of claims 7-8, wherein the plate is provided with two parallel break lines (12) located on either side of the opening (11), at a distance D from the opening (11) which is less than 10 mm, for breaking off the side pieces of the plate (10), depending on the application. [10] Mounting unit according to one of claims 7-9, wherein the thickness of the plate is less than 3 mm. [11] Mounting unit according to one of the preceding claims, wherein the first and / or the second tubular part is / are made of plastic. [12] A method for mounting a mounting unit according to any one of claims 1-11 in a wall W having a front face V and having an opening O2 extending from the front face, comprising: - mounting the second tubular part (30) in a suitable position in the first tubular part (20). [13] A method according to claim 12, wherein the second tubular member is attached by clipping it into the first tubular member in a desired position. [14] A method according to any one of claims 12-13, wherein the position of the second tubular member, after it has been clipped into the first tubular member, is further adjusted by rotating the second tubular member with respect to the first tubular member. [15] A method according to any one of claims 12-14, wherein the height of the second tubular part is adjusted depending on the thickness of a plaster layer to be applied, whereupon the plaster layer is applied to the wall.
