[0001] The present disclosure relates to an assembly for mounting a rosette or another ornamental
element to a ceiling or a wall, such as to a lamp outlet at the ceiling or on the
wall, and a system comprising the assembly and a rosette or another ornamental element.
Also, a method for mounting a rosette or another ornamental element is disclosed.
BACKGROUND
[0002] Renovating older style buildings often faces the problem of having to comply with
new building and safety standards while maintaining the original architectural style
of the building. In particular, this problem arises when considering electrical installations
where safety standards have significantly changed.
[0003] In many older buildings, lamp outlets are decorated with stucco rosettes, which may
be damaged or dismounted when modernising the electrical installation. It is, however,
cumbersome, expensive, and sometimes not even possible to reconstruct or remount the
original rosette. Thus, it would be advantageous to provide elements and methods which
would aid mounting of a rosette or another ornamental element. Such advantageous elements
and/or method could also beneficially used in mounting decorative elements in new
buildings.
SUMMARY
[0004] It is an object of the present disclosure to provide an easier, more convenient,
and possibly more cost-efficient way to provide modern electrical installations with
a desired look. The desired look may be a classical look. However, the present disclosure
may just as well be used to provide the electrical installation with a certain modern
look or any other desired look. Thus, it is a further object of the present disclosure
to provide an assembly which is largely agnostic as to the desired look but provides
a flexible platform, which may be used for attaching a wide variety of different shapes,
such as custom-made shapes, to allow for individualised looks.
[0005] Thus, the present disclosure relates to an assembly for mounting a rosette or another
ornamental element to a ceiling or a wall, such as to a lamp outlet at the ceiling
or on the wall. The present disclosure also relates to a system comprising the assembly
and a rosette or another ornamental element for being mounted to a ceiling or a wall,
such as to a lamp outlet, by the assembly, and a method for mounting a rosette or
another ornamental element.
GENERAL DESCRIPTION
[0006] The disclosed assembly comprises a first part extending along a first part axis between
a primary first part end and a secondary first part end.
[0007] The first part has a first primary part being attachable to the ceiling or the wall.
For example, the first primary part may be attachable to the lamp outlet at the ceiling
or on the wall, such as to an electrical box of the lamp outlet. The first primary
part may form the primary first part end. The first primary part has a first primary
diameter perpendicular to the first part axis. The first primary part and/or the first
primary diameter may be adapted so that the first primary part is configured to cover
the electrical box. For example, the first part may have a first primary diameter
larger than the electrical box, e.g. larger than a diameter and/or a maximal width
of the electrical box. The first primary diameter may be between 60-100 mm, such as
between 70-80 mm.
[0008] The first part further has a first secondary part attached to the first primary part.
The first secondary part has a first secondary diameter perpendicular to the first
part axis. The first secondary diameter is smaller than the first primary diameter.
The first secondary diameter may be between 30-50 mm, such as between 35-45 mm. The
first secondary part extends along the first part axis from the first primary part
to the secondary first part end. The first secondary part may form the secondary first
part end.
[0009] The assembly comprises a second part extending along a second part axis between a
primary second part end and a secondary second part end. The second part has a cavity.
The cavity extends along the second part axis from the primary second part end. The
cavity is configured for receiving (e.g. rotatably receiving) and engaging with the
first secondary part of the first part. When the first secondary part is received
in the cavity, the first part axis and the second part axis may be parallel and/or
coinciding. The second part has an outer diameter at the primary second part end.
The outer diameter at the primary second part end is larger than the first primary
diameter. The outer diameter at the primary second part end may be between 70-110
mm, such as between 85-95 mm.
[0010] The outer diameter at the primary second part end may be at least 15 mm larger than
the first primary diameter, such as at least 18 mm larger than the first primary diameter.
Providing an outer diameter at the primary second part end which is notably larger
than the first primary diameter (e.g. at least 15 mm or at least 18 mm larger) has
been found by the present inventors to allow retaining a rosette or another ornamental
element made of plaster without failing. Similar dimensions may also allow sufficient
retainment of rosettes and other ornamental elements made of other materials.
[0011] The cavity of the second part may have a stop element. The stop element may be adapted
to abut the secondary first part end of the first part. The stop element may prevent
engagement of the first secondary part beyond the stop element. The stop element may
be a bottom wall or an internal edge of the cavity.
[0012] The first part may have a first length along the first part axis from the primary
first part end to the secondary first part end. The first length may be between 20-65
mm, such as between 25-60 mm, such as between 30-55 mm.
[0013] The first primary part may have a first primary length along the first part axis
from the primary first part end to the first secondary part. The first primary length
may be between 5-20 mm, such as between 10-15 mm. The first primary length may be
considered as the thickness of the first primary part.
[0014] The first secondary part may have a first secondary length along the first part axis
from the first primary part to the secondary first part end. The first secondary length
may be between 15-55 mm, such as between 20-45 mm. The first secondary length may
be at least 15 mm, such as at least 20 mm, such as at least 25 mm. The first secondary
length having a certain minimum length may ensure sufficient engagement between the
second part and the first part, so that they do not disengage unintentionally.
[0015] The cavity has a cavity depth along the second part axis, e.g. from the primary second
part end to the stop element. The cavity depth may be shorter than the first length.
For example, the cavity depth may be 5-25 mm shorter than the first length, such as
10-20 mm shorter. The difference between the cavity depth and the first length may
correspond to a thickness of the rosette or the other ornamental element to be mounted,
such as a thickness of a base thereof. For example, the difference between the cavity
depth and the first length may be the same or larger than the thickness of the rosette
or the other ornamental element. The cavity depth may be equal to or shorter than
the first secondary length.
[0016] The second part may have a second length along the second part axis between the primary
second part end and the secondary second part end. The second length may be longer
than the first secondary length. The second length may be at least 20 mm, such as
at least 25 mm, such as at least 30 mm. The second part having such minimum second
length facilitates coupling of the second part and the first part. Especially the
second length being of a certain size allows the outer surface to be substantially
smooth, while still allowing a person to rotate the second part when engaging with
the first part. In some examples, the second length may be between 30-65 mm, such
as between 40-50 mm.
[0017] The first primary part and the first secondary part may be substantially circular.
The first primary part and the first secondary part may be arranged concentrically
relative to the first part axis.
[0018] The first secondary part may have an outer threading. The cavity of the second part
may have an inner threading. The inner threading of the cavity may be complementary
to the outer threading of the first secondary part, so that the first secondary part
may be engaged with the cavity by rotation of the second part relative to the first
part. In some examples, one of the outer threading and the inner threading may instead
be a protrusion or a plurality of protrusions to engage with the threading of the
other element.
[0019] The second part may be made of porcelain. In another example, the second part may
be made of metal, such as aluminium, brass or copper.
[0020] The second part may comprise a second primary part. The second primary part may be
made of porcelain. In another example, the second primary part may be made of metal,
such as aluminium, brass or copper. The second part may comprise a second secondary
part. The second secondary part may be made of plastic, e.g. LCP (liquid-crystal polymer)
or ABS (Acrylonitrile butadiene styrene). The inner threading of the cavity may be
formed by the second secondary part. The second secondary part and the second primary
part may be glued together, e.g. by two component epoxy glue or another suitable adhesive.
[0021] The second part may have a second outer diameter at the secondary second part end.
The second outer diameter at the secondary second part end may be smaller than the
outer diameter at the primary second part end. Thus, the second part may have a cone
shape, such as a truncated cone shape. The second outer diameter may be between 10-70
mm, such as between 30-55 mm, such as between 40-50 mm.
[0022] The second part may have an opening to the cavity at the secondary second part end.
The second part may have a portion at the secondary second part end adapted to facilitate
formation of the opening to the cavity. The opening may be coaxial with the second
part axis. The opening may have an opening diameter. The opening diameter may be smaller
than an internal diameter of the cavity. The opening diameter may be smaller than
the first secondary diameter. Not having the opening or having an opening with an
opening diameter smaller than the first secondary diameter may prevent that the second
part is erroneously, e.g. oppositely, attached to the first part. The opening diameter
may be between 5-40 mm. For example, the opening diameter may be between 10-30 mm,
such as between 11-27 mm, such as between 14-27 mm. Alternatively, the opening diameter
may be less than 15 mm, such as less than 10 mm, such as between 5-10 mm. Alternatively
or additionally, the opening diameter may be less than 7 mm.
[0023] The first secondary part may form a lightbulb socket, e.g. a threaded socket, e.g.
an Edison screw. The lightbulb socket may be at the secondary first part end of the
first part, e.g. extending from the secondary first part end. The lightbulb socket
may be adapted to receive a base of a light bulb.
[0024] The first primary part may comprise one or more sets of fastening holes. The one
or more sets of fastening holes may be arranged between the first secondary part and
an outer perimeter of the first primary part. The one or more sets of fastening holes
may include one or more fastening holes which are keyhole shaped, e.g. comprising
a hole and a slot and/or a hole and two slots.
[0025] The first primary part may comprise a perimeter wall along the outer perimeter of
the first primary part. The perimeter wall may be substantially parallel to the first
part axis. The perimeter wall may comprise one or more perimeter wall openings. The
perimeter wall openings may allow a cable extending from the outside to the inside
of the first primary part, e.g. to the electrical box to which the first primary part
may be attached. Alternatively or additionally, the perimeter wall openings may allow
a cable extending from another external lamp outlet to the inside of the first primary
part. In some examples, the perimeter wall comprises a portion adapted to facilitate
formation of the perimeter wall opening.
[0026] The disclosed system may comprise the assembly and a rosette or another ornamental
element for being mounted to a ceiling or a wall, such as to a lamp outlet at the
ceiling or on the wall, by the assembly. The rosette or the other ornamental element
may have a substantially planar base with an aperture. The aperture may have an aperture
diameter. The aperture diameter may be larger than the first primary diameter. The
first primary diameter may be smaller than the aperture diameter. The aperture diameter
may be smaller than the outer diameter at the primary second part end of the second
part. The outer diameter at the primary second part end of the second part may be
larger than the aperture diameter. The aperture diameter may be between 60-90 mm,
such as between 70-80 mm, such as between 70-75 mm.
[0027] The rosette or the other ornamental element is preferably made of plaster. However,
other materials, such as plastic or wood may also be used.
[0028] The outer diameter of the second part at the primary second part end may be at least
15 mm larger, such as at least 18 mm larger, than the aperture diameter of the rosette
or the other ornamental element. By having such minimum difference, the inventors
have found that a rosette or another ornamental element made of plaster may be retained
without failing. Similar dimensions may also allow sufficient retainment of rosettes
and other ornamental elements made of other materials.
[0029] The base of the rosette or the other ornamental element may have a thickness, e.g.
perpendicular to the aperture diameter, e.g. parallel to the first part axis and the
second part axis when mounted. The thickness of the base may be less than 20 mm, such
as less than 10 mm. In some examples, the thickness of the base may be between 10-20
mm.
[0030] The disclosed method for mounting a rosette or another ornamental element, may be
a method for mounting the rosette or the other ornamental element as described above,
e.g. to a ceiling or a wall, , such as to a lamp outlet at the ceiling or on the wall.
Particularly, the rosette or the other ornamental element may have a substantially
planar base with an aperture having an aperture diameter.
[0031] The disclosed method may include providing one or more elements of the disclosed
assembly and/or system. For example, the method may comprise providing the first part
and attaching the first part to the ceiling or the wall, such as to the lamp outlet
at the ceiling or on the wall, such as to the electrical box of the lamp outlet, e.g.
so that the first primary part covers the electrical box.
[0032] After attaching the first part to the ceiling or the wall, the method may comprise
arranging the rosette or the other ornamental element such that the first part extends
through the aperture of the base and such that the base abuts the ceiling or the wall.
[0033] The method may also comprise providing the second part and while the rosette or the
other ornamental element is arranged such that the first part extends through the
aperture of the base and such that the base abuts the ceiling or the wall (for example,
the rosette or the other ornamental element may be held in place by hand), attaching
the second part to the first part by engagement between the first secondary part of
the first part and the cavity of the second part, e.g. to a position where the stop
element abuts the secondary first part end of the first part.

DETAILED DESCRIPTION
[0035] Various exemplary embodiments and details are described hereinafter, with reference
to the figures when relevant. It should be noted that the figures may or may not be
drawn to scale and that elements of similar structures or functions are represented
by like reference numerals throughout the figures. It should also be noted that the
figures are only intended to facilitate the description of the embodiments. They are
not intended as an exhaustive description of the invention or as a limitation on the
scope of the invention. In addition, an illustrated embodiment needs not have all
the aspects or advantages shown. An aspect or an advantage described in conjunction
with a particular embodiment is not necessarily limited to that embodiment and can
be practiced in any other embodiments even if not so illustrated, or if not so explicitly
described.
[0036] Fig. 1 schematically illustrates an exemplary system 2 comprising a rosette (which
alternatively could be another ornamental element) 100 for being mounted to a ceiling
or a wall 6. In the illustrated example, the rosette is being mounted to a lamp outlet
4 at the ceiling or on the wall 6. The system 2 comprises an assembly 10, alternatively
denoted a mount assembly, for mounting the rosette 100 or another ornamental element
to the ceiling or the wall, such as to the lamp outlet 4. The assembly 10 comprises
a first part 20 and a second part 50. The first part 20 has a first primary part 30
and a first secondary part 40. The first primary part 30 is attachable to the ceiling
or the wall 6. In the illustrated example, the first primary part 30 is attachable
to an electrical box 5 of the lamp outlet 4, e.g. by having one or more sets of fastening
holes 32 aligned with corresponding fastening receivers of the electrical box 5. The
first secondary part 40 is attached to the first primary part 30, e.g. by glueing,
welding, screwing or other known fastening methods. The first secondary part 40 and
the first primary part 30 may also be attached by being cast or moulded as a single
monolithic element.
[0037] The second part 50 has a cavity 56 (see Fig. 3a) configured for receiving and engaging
with the first secondary part 40, e.g. by rotation of the second part 50. Thereby,
the rosette 100 may be fastened to the ceiling or wall 6 by having a base part arranged
between the ceiling or wall 6 and the second part 50.
[0038] Fig. 2a schematically illustrates a side view of an exemplary first part 20 of the
assembly 10, as exemplified in Fig. 1. Fig. 2b schematically illustrates a top view
of the exemplary first part 20 of the assembly 10.
[0039] The first part 20 extends along a first part axis Ax1 between a primary first part
end 22 and a secondary first part end 24. The first part has a first primary part
30. The first primary part 30 forms the primary first part end 22. The first part
has a first secondary part 40. The first secondary part 40 extends along the first
part axis Ax1 from the first primary part 30 to the secondary first part end 24. The
first secondary part 40 forms the secondary first part end 24.
[0040] The first primary part 30 is substantially circular. However, in other examples,
the first primary part 30 may be rectangular, pentagonal or another suitable shape.
The first secondary part 40 is substantially circular. The first primary part 30 and
the first secondary part 40 are arranged concentrically relative to the first part
axis Ax1.
[0041] The first primary part 30 has a first primary diameter D11 perpendicular to the first
part axis Ax1. The first primary part 30 is attachable to the ceiling or the wall
6. In some examples, the first primary part 30 is attachable to the electrical box
5 (see Fig. 1). The first primary diameter D11 may be adapted so that the first primary
part 30 can cover the electrical box 5. Thus, the first primary diameter D11 may be
larger than a diameter De of the electrical box 5 (see Fig. 1), such as larger than
a maximal width of the electrical box 5.
[0042] The first secondary part 40 has a first secondary diameter D12 perpendicular to the
first part axis Ax1. The first secondary diameter D12 may be parallel to the first
primary diameter D11. The first secondary diameter D12 is smaller than the first primary
diameter D11.
[0043] The first part 20 has a first length L1 along the first part axis Ax1. The first
length L1 is from the primary first part end 22 to the secondary first part end 24.
[0044] The first primary part 30 has a first primary length L11 (which may alternatively
be expressed as the thickness of the first primary part 30) along the first part axis
Ax1. The first primary length L11 is from the primary first part end 22 to first secondary
part 40.
[0045] The first secondary part 40 has a first secondary length L12 along the first part
axis Ax1. The first secondary length L12 is from the first primary part 30 to the
secondary first part end 24.
[0046] The first secondary part 40 has an outer threading 42. The outer threading 42 is
adapted to cooperate with a complementary threading of the second part 50 (see Figs.
3a-3c).
[0047] The first secondary part 40 may form a lightbulb socket 44 adapted to receive a base
of a light bulb. The lightbulb socket 44 may be formed at the secondary first part
end 24 of the first part 20. For example, the first secondary part 40 may have an
inner threading forming an Edison screw 46. In an alternative, the first secondary
part 40 may comprise a bi-pen socket, such as a GU 10 socket.
[0048] The first primary part 30 comprises one or more sets of fastening holes 32. The fastening
holes 32 are arranged between the first secondary part 40 and an outer perimeter of
the first primary part 30. Thereby, the first part 20 may be easily fastened to the
wall or the ceiling 6 and/or to the electrical box 5 (see Fig. 1). The fastening holes
32 may be keyhole shaped, e.g. comprising a hole 32A and a slot 32B and/or a hole
32A and two slots 32B, as illustrated. Thereby, screws for fastening the first primary
part may initially be attached to the wall or ceiling 6 or to the electrical box 5,
and afterwards, the first part 20 may be slid onto the screws with the head of the
screws passing through the holes 32A of the keyhole shaped fastening holes 32. Subsequently,
the first part 20 may be rotated around the first part axis Ax1, translating the screws
into the slots 32B of the keyhole shaped fastening holes 32, and the screws may be
tightened.
[0049] The first primary part 30 comprises a perimeter wall 34 along the outer perimeter
of the first primary part 30. The perimeter wall 34 may comprise one or more perimeter
wall openings 36. The perimeter wall openings 36 may allow access through the first
primary part 30 for cables extending along the wall or ceiling and into the electrical
box 5. Alternatively, the perimeter wall openings 36 may allow access for cables from
an external source, such as an external lamp outlet, and into the first primary part
30. In some examples, the first primary part 30 may be provided with sections for
forming the perimeter wall opening(s) 36. For example, the perimeter wall 34 may comprise
perforations and/or thinned wall sections allowing a user to form one or more of the
perimeter wall opening(s) 36 at certain predefined positions.
[0050] Figs. 3a-3c schematically illustrate an exemplary second part 50 of the assembly
10, as exemplified in Fig. 1. Fig. 3a schematically illustrates a perspective view
of the exemplary second part 50. Fig. 3b schematically illustrates a cross-sectional
view of the exemplary second part 50. Fig. 3c schematically illustrates an exploded
view of the exemplary second part 50.
[0051] The second part 50 extends along a second part axis Ax2. The second part 50 extends
along the second part axis Ax2 between a primary second part end 52 and a secondary
second part end 54. The second part 50 has a second length L2 along the second part
axis Ax2. The second length L2 is between the primary second part end 52 and the secondary
second part end 54. The second length L2 may be longer than the first secondary length
L12 (see Fig. 2a).
[0052] The second part 50 has a cavity 56 extending along the second part axis Ax2 from
the primary second part end 52. In some examples, the cavity 56 may extend through
the second part 50, i.e. from the primary second part end 52 to the secondary second
part end 54. The cavity 56 is configured for receiving and engaging with the first
secondary part 40 of the first part 20 (see. Fig. 1), e.g. by rotation.
[0053] The cavity 56 has an inner threading 60. The inner threading is complementary to
the outer threading 42 of the first secondary part 40 (see Fig. 2a). Thus, the first
secondary part 40 may be engaged with the cavity 56 by rotation of the second part
50 relative to the first part 20. The inner threading 60 may be provided by a second
secondary part 68, e.g. made of a suitable plastic (e.g. liquid-crystal polymer (LCP)
or Acrylonitrile butadiene styrene (ABS)), which may be attached, e.g. by an adhesive,
to a second primary part 66 to form the second part 50. The second primary part 66
may be made of porcelain. Manufacturing the second part 50 by providing the threaded
part (the second secondary part 68) in one material and the major part (the second
primary part 66) in another material simplifies and eases production, especially if
certain material, such as porcelain, glass, wood, etc., is desired for the outer part
(the second secondary part 68). In some examples, the second part 50 may be cast or
moulded as a single monolithic element comprising the inner threading 60. The second
part 50 may be made of aluminium or another suitable material facilitating such process.
[0054] The cavity 56 has a stop element 58. The stop element 58 may be adapted to abut the
secondary first part end 24 of the first part 20 (see Fig. 2a) and prevent engagement
of the first secondary part 40 beyond the stop element 58. Thereby, a minimum distance
between the wall or ceiling and the primary second part end 52 may be maintained,
reducing the risk of overtightening the assembly, which otherwise may cause unwanted
and excessive load on the electrical box or the fastening means used to fasten the
assembly to the wall or the ceiling. The stop element 58 may be an internal edge,
as illustrated. In alternative examples, the stop element 58 may be a protrusion or
a bottom wall of the cavity 56.
[0055] The cavity has a cavity depth Lc along the second part axis Ax2. The cavity depth
Lc is from the primary second part end 52 to the stop element 58. The cavity depth
may be shorter than the first length L1 (see Fig. 2a), e.g. between 10 and 20 mm shorter
than the first length. In some examples, the cavity depth may be equal to or shorter
than the first secondary length L12 (see Fig. 2a).
[0056] The second part 50 has an outer diameter Do1 at the primary second part end 52. The
second part has an outer diameter Do2 at the secondary second part end 54, which may
be different, e.g. smaller, than the outer diameter Do1 at the primary second part
end 52. The outer diameter Do1 at the primary second part end 52 is larger than the
first primary diameter D11 of the first part 20, e.g. at least 15 mm larger. Thus,
the second part 50 is able to maintain the rosette 100 (see Fig. 1) against the wall
or ceiling when the rosette 100 has an aperture large enough to cover the first primary
part 30.
[0057] The second part 50 has an opening 62 to the cavity 56 at the secondary second part
end 54. In some examples the second part may have a portion adapted to facilitate
formation of the opening 62 to the cavity 56. For example, a perforation or a thinned
wall may be provided, allowing a user to form the opening 62 during use of the second
part 50. The opening 62 has an opening diameter Dop smaller than an internal diameter
Dc of the cavity 56. In some examples, the opening diameter Dop may be adapted to
receive a standard light bulb socket, e.g. being between 5 mm and 40 mm, such as between
14 mm and 27mm.
[0058] Fig. 4a schematically illustrates a top view of an exemplary rosette 100 of the system
2, as exemplified in Fig. 1. Fig. 4b schematically illustrates a side view of the
exemplary rosette 100. The rosette 100 may be mounted to a wall or a ceiling by use
of the assembly 10, as described in relation to Fig. 1. In some examples, the rosette
100 is made of plaster.
[0059] The rosette 100 has a substantially planar base 102 with an aperture 104 having an
aperture diameter Da. The aperture diameter is larger than the first primary diameter
D11 (see Fig. 2a) and smaller than the outer diameter Do1 at the primary second part
end 52 of the second part 50 (see Fig. 3b). In some examples, the outer diameter Do1
of the second part 50 at the primary second part end 52 is at least 15 mm larger than
the aperture diameter Da.
[0060] The base 102 of the rosette 100 has a thickness Tb. The thickness Tb of the base
102 may, for example, be between 10-20 mm. In some examples the thickness Tb of the
base 102 may be less than 10 mm.
[0061] As mentioned, the rosette 100 is merely an example of the element which may be mounted
to the wall or the ceiling 6 by the assembly 10 (see Fig. 1). However, in case another
ornamental element is to be mounted by the assembly 10, the other ornamental element
should preferably also have a substantially planar base 102 with an aperture 104 having
the aperture diameter Da like the exemplified rosette 100. The base 102 of the other
ornamental element may, like the base 102 of the rosette 100, also have a thickness
Tb, e.g. between 10-20 mm. In some examples the thickness Tb may be less than 10 mm.
[0062] Fig. 5 schematically illustrates a cross-sectional view of the exemplary system 2,
as illustrated in Fig. 1. In the illustrated example, also a light bulb 8 is illustrated
being inserted in the assembly 10. In the cross section, it is seen how the first
part 20 may be attached to the electrical box 5, the rosette 100 is fitted over the
first part 20, and the second part 50 is attached to the first secondary part 40 of
the first part 20 to retain the rosette 100 against the wall or ceiling 6.
[0063] As is visible from Fig. 5, the first primary diameter D11 of the first primary part
30 may be larger than the diameter De of the electrical box 5 so that the first primary
part 30 is covering the electrical box 5. It is also visible in Fig. 5 that when the
first part 20 and the second part 50 are engaged, the first part axis Ax1 and the
second part axis Ax2 are coinciding.
[0064] It is also visible from Fig. 5 that the outer diameter Do1 of the second part 50
at the primary second part end 52 is larger than the first primary diameter D11 of
the first primary part 30, which provides for the portion of the second part 50 retaining
the rosette 100 against the wall or ceiling 6. This difference is preferably at least
15 mm, such as at least 18 mm, to allow a sufficient area of overlap with the rosette
100. At the same time, this relationship allows that the rosette 100 may be provided
such that it completely encapsulates and/or hides the electrical box 5 and the first
part 20.
[0065] It is also seen how the stop element 58 may prevent further engagement of the first
secondary part 40 beyond the stop element 58 by abutting the secondary first part
end 24 of the first part 20. It is also visible how the stop element 58 in effect
may prevent unnecessary squeezing of the base 102 of the rosette 100, which otherwise
would cause an unwanted pulling force on the electrical box 5 or any fastening means
attaching the assembly to the wall or ceiling or to the electrical box, potentially
pulling the electrical box 5 and/or the fastening means out of the ceiling or wall
6.
[0066] Figs. 6a and 6b schematically illustrate another exemplary second part 50'. Fig.
6a schematically illustrates a perspective view of the exemplary second part 50'.
Fig. 6b schematically illustrates a top view of the exemplary second part 50'. The
second part 50' as illustrated in Figs. 6a and 6b differs from the previous examples
of the second part 50 in that the opening diameter Dop of the opening 62 to the cavity
56 at the secondary second part end 54 is smaller than in the previous examples. As
previously described, the second part 50 may have a portion adapted to facilitate
formation of the opening 62. For example, a perforation or a thinned wall. In the
example as illustrated in Figs. 6a and 6b, the opening diameter Dop may be adapted
to receive an electrical cable. Thus, the second part 50' may allow for one or more
cables extending thereto and to a lamp, e.g. a pendant lamp. The opening diameter
Dop may be less than 15 mm, such as less than 10 mm, such as less than 7 mm.
[0067] As also illustrated in Figs. 6a and 6b, the opening 62 may be non-circular. In such
situation, the opening diameter Dop of the opening 62 may be given by the inscribed
circle of the opening 62.
[0068] The disclosure has been described with reference to a preferred embodiment. However,
the scope of the invention is not limited to the illustrated embodiment, and alterations
and modifications can be carried out without deviating from the scope of the invention.
[0069] Throughout the description, the use of the terms "first", "second", "third", "fourth",
"primary", "secondary", "tertiary" etc. does not imply any particular order or importance
but are included to identify individual elements. Furthermore, the labelling of a
first element does not imply the presence of a second element and vice versa.
