Technical Field of the Invention
[0001] The present invention relates to a mounting device for a lighting fixture suspended
by a suspension means. The suspension means is connected to the mounting device by
a connection means and the mounting device comprises an adjustment means which comprises
at least one rotatable member. Furthermore, the invention relates to the use of a
mounting device according to the invention for any object suspended from above.
Background of the Invention
[0002] In the following, the term "lighting fixture" is to be construed as an object that
provides light to for instance a building. A lighting fixture may comprise a light
source such as a lamp and a number of elements that serve to spread the light as desired
and to enable the lighting fixture to integrate well with its surroundings.
[0003] It is widely used to suspend lighting fixtures and other objects from above by means
of suspension means. Examples would be lighting fixtures suspended from ceilings,
from staircases, from beams, etc. The advantage of suspending from above is that it
makes it easy to adjust the height of the lighting fixture from the floor, and the
relative simplicity of the suspension means enables a simple mounting of the lighting
fixture by for instance means of a hook or another simple connection means. In its
simplest form, the electric cable will be used as suspension means, thus providing
electricity to the lighting fixture as well as suspending it from above. In more advanced
forms, the suspension means is a separate item such as a wire, a tube, a rope, a chain,
a rod, a cable. These are preferable if for instance the lighting fixture is too heavy
to be suspended in the electric cable or if a certain visual appearance of the lighting
fixture is desired. When a separate suspension means is applied, the electrical cable
can either be integrated in the suspension means or guided along with it. To enable
safe connection of the suspension means as well as the electric cable to the lighting
fixture, it is common to mount the electric cable and the suspension means to the
lighting fixture by means of a mounting piece.
[0004] Often, lighting fixtures are vital parts of a building's interior, putting certain
requirements to the lighting fixtures' functional and visual design. The art of designing
lighting fixtures that fit the requirements to function as well as aesthetics is closely
linked to how the lighting fixtures are mounted. Optimally, the means for mounting
the lighting fixture to for instance a suspension means from above should not constrain
the visual design of the lighting fixture. A common way to overcome this is to place
the actual connection of the suspension means to the lighting fixture inside the mounting
piece, which is then integrated in the lighting fixture's visual design.
[0005] When lighting fixtures are to be mounted to suspension means hanging from above,
it is preferable that the mounting piece is easy to reach, thus enabling a fast and
safe mounting of the lighting fixture. Also, it is an advantage if the mounting can
be carried out without the use of special tools or even without any tools at all.
[0006] It may be advantageous to design mounting pieces in such a manner that one mounting
piece can fit more than one type of lighting fixture. This is for instance achieved
by providing the mounting piece with adjustable elements, such as two plate elements
with a range of punched holes for a pin to fit in, whereby for instance the attachment
point of the electric cable can be altered. A drawback to the adjustable mounting
pieces is that they tend to comprise several components in order to provide the desired
versatility, which make them more expensive. Furthermore, the many components tend
to require more space, resulting in a larger mounting piece which puts larger constraints
on the visual design and the functional design of the lighting fixture itself.
[0007] When suspending a lighting fixture or another object in a suspension means, the centre
of gravity of the lighting fixture and the attachment point of the suspension means
will be in the same vertical line. Hence, if the attachment point or the centre of
gravity varies from lighting fixture to lighting fixture, the lighting fixture suspended
from above will tilt and the visual impression of the lighting fixture will be damaged.
This is especially a problem in hand-made productions or productions with irregularities
in the shaping operations. This problem is usually solved by incorporating several
adjustment means in the mounting piece in order to enable adjustments in several directions
to compensate for the irregularities.
[0008] In situations where the visual appearance of the lighting fixture is important, it
is preferable if the inclination of the lighting fixture to the vertical can be adjusted
while the lighting fixture is suspended from above, so that the lighting fixture does
not have to be dismounted to make an adjustment. Furthermore, it is desirable if the
adjustment of the inclination can be done in a very precise and detailed manner so
that even small undesired inclinations can be corrected. This is especially important
in the case of lighting fixtures from hand-made productions as those mentioned in
the above.
[0009] Mounting pieces for commercially produced lighting fixtures should preferably be
as simple as possible in order to keep manufacturing costs as low as possible. At
the same time, the mounting piece should meet the above-stated requirements. As indicated,
the requirements to adaptability, user-friendliness and aesthetics are in the current
art met by quite sophisticated mounting pieces with several components, which suffer
from the drawback of being expensive, unable to adjust while mounted and tending to
be rather big. In other words, there is a need for a mounting piece that is cheap
to manufacture while at the same time being small, easy to use, easy to reach, and
provides an easy, detailed and precise inclination adjustment.
DE 20 2005 015 148 U1 describes a hanging lamp suspended from a suspension means and an adjustment means
for positioning the vertically suspended hanging lamp, the adjustment means being
arranged between the hanging lamp and the suspension means and comprising two rotatable
members for adjusting the position of the hanging lamp.
Summary of the Invention
[0010] An object of the present invention is to wholly or partly overcome the above disadvantages
and drawbacks of the prior art. More specifically, it is an object to provide a mounting
device for a lighting fixture suspended from above by a suspension means, said suspension
means being connected to said mounting device by a connection means, said mounting
device comprising an adjustment means comprising at least one rotatable member, in
which said lighting fixture's inclination (α) from the vertical is adjustable by rotation
of at least one of said rotatable members, wherein said connection means comprises
a spherical member being attached to an end of said suspension means. This is advantageous,
as it enables a rotatable connection between said suspension means and said connection
means. This is furthermore advantageous, if for instance a plurality of suspended
lighting fixtures have varying centres of gravity, as the rotation of the rotatable
member effects a change in the lighting fixtures' inclination to the vertical, thus
compensating from any tilting caused by the varying centres of gravity.
[0011] The mounting device according to the invention may be so that said lighting fixture's
inclination from the vertical is adjustable by said adjustment means in a step-less
manner. This is advantageous, as it enables detailed adjustment of the lighting fixture's
inclination to the vertical, for instance in order to compensate for varying centres
of gravity.
[0012] The mounting device according to the invention may be so that said lighting fixture's
inclination from the vertical is adjustable by said adjustment means in a plurality
of steps. This is advantageous, if for instance a quick and simple adjustment of the
lighting fixture's inclination to the vertical is desired.
[0013] The mounting device according to the invention may be so that one rotation of at
least one of said rotatable members effects a change of said lighting fixture's inclination
(a) from the vertical of less than 10 degrees, but preferably less than 3 degrees.
Such a large transmission ratio between the change in inclination and the rotation
of the rotatable member is advantageous as it enables a very detailed adjustment of
the inclination, seeing that it takes several rotations of a rotatable member to effect
a change in the lighting fixture inclination.
[0014] The mounting device according to the invention may be so that said connection means
is connected to at least one of said rotatable members. This is advantageous, as it
enables a rotatable member to directly cause a change in the connection means' position
relative to the mounting device, and thus also a change in the point in which the
lighting fixture is suspended, which can change the lighting fixture's inclination
to the vertical.
[0015] The mounting device according to the invention may be so that rotation of at least
one of said rotatable members effects a displacement of said connection means relative
to said lighting fixture. This is advantageous as it enables rotation of a rotatable
member to indirectly change the lighting fixture's inclination to the vertical.
[0016] The mounting device according to the invention may be so that said connection means
comprises a threaded member being attached to an end of said suspension means. This
is advantageous as it enables a rotatable connection between said connection means
and other members.
[0017] The mounting device according to the invention may comprise a first rotatable member
and a second rotatable member, in which said first rotatable member engages said second
rotatable member. This is advantageous, as it enables a transmission ratio between
said first rotatable member and said second rotatable member, which makes it possible
to vary the degree of the adjustment of the lighting fixture's inclination to the
vertical caused by rotation of one of the rotatable members.
[0018] The mounting device according to the invention may be so that at least one of said
rotatable members comprises a thread.
[0019] The mounting device according to the invention may be so that at least one of said
rotatable members comprises a helical thread.
[0020] The mounting device according to the invention may be so that at least one of said
rotatable members comprises a plurality of gear teeth comprising leading edges projecting
radially from the axis of rotation of said rotatable members.
[0021] The mounting device according to the invention may be so that at least one of said
rotatable members comprises a plurality of gear teeth comprising leading edges projecting
radially towards the axis of rotation of said rotatable members.
[0022] The mounting device according to the invention may be so that at least one of said
rotatable members comprises a plurality of gear teeth comprising leading edges parallel
to the axis of rotation of said rotatable members.
[0023] The mounting device according to the invention may be so that at least one of said
rotatable members comprises a plurality of gear teeth comprising leading edges orthogonal
to the axis of rotation of said rotatable members.
[0024] The mounting device according to the invention may be so that at least one of said
rotatable members comprises a plurality of gear teeth comprising leading edges angular
to the axis of rotation of said rotatable members.
[0025] The mounting device according to the invention may be so that said plurality of gear
teeth is dispersed over a segment of the surfaces of said rotatable members. This
is advantageous, as it enables connection of other members to the surfaces of said
rotatable members without gear teeth.
[0026] The mounting device according to the invention may be so that at least one of said
rotatable members is a spur gear.
[0027] The mounting device according to the invention may be so that at least one of said
rotatable members is a bevel gear.
[0028] The mounting device according to the invention may be so that at least one of said
rotatable members is a helical gear.
[0029] The mounting device according to the invention may be so that at least two of said
rotatable members form a worm gear. This is advantageous, as a worm gear may provide
a very large transmission ratio between rotatable members, which enables a very detailed
adjustment of the lighting fixture's inclination to the vertical.
[0030] The mounting device according to the invention may comprise at least one member with
a linear rack of teeth. This is advantageous, as it enables conversion of rotational
motion to linear motion, which for instance can be applied to make a rotatable member
effect a linear movement of said connection means.
[0031] The mounting device according to the invention may comprise at least one member comprising
an internal thread. This is advantageous, as it for instance can be applied to convert
the rotational motion of a member comprising a helical thread into a linear motion
of said member comprising an internal thread.
[0032] An additional object of the invention is to provide the use of a mounting device
according to the invention for any object suspended from above.

Detailed Description of Preferred Embodiments
[0035] Fig. 1 shows a preferred embodiment of a mounting device 1 according to the invention
used for a lighting fixture 2 suspended from above by a suspension means 3. Section
(a) of figure 1 shows the mounting device 1 in a top view and in a side view the mounting
device and the lighting fixture. As shown, the mounting device 1 comprises a connection
means 4 and an adjustment means 5 comprising a rotatable member 6. Also, the mounting
device 1 shown in section (a) of figure 1 comprises a cable guide 22, for the electrical
cable (not shown) supplying electricity to the lighting fixture. The centre of gravity
P of the lighting fixture shown in section (a) of figure 1 is slightly displaced from
the lighting fixtures' centre axis V. As indicated in section (a) of figure 1, the
suspension means 3 is connected to the connection means 4 in a suspension point Q,
and the suspension point Q and the centre of gravity P are thus situated in the same
vertical line QP by the laws of gravity. Since the lighting fixture's centre of gravity
P is not situated in the lighting fixture's centre axis V, the lighting fixture has
an inclination α to the vertical. According to the invention, the lighting fixture's
inclination α from the vertical can be adjusted by rotation of the rotatable member
6. When the rotatable member 6 is rotated, the suspension point Q is moved relative
to the lighting fixture's centre axis V as shown in figure 1, where the suspension
point Q is moved from one position in section (a) to another position in section (b),
effected by a rotation of the rotatable member 6. By moving the suspension point Q
relative to the centre axis V, the inclination of the line QP relative to the lighting
fixture's centre axis V changes. When the line QP is parallel to the centre axis V,
the lighting fixtures' inclination α to the vertical is zeroed, which is the state
shown in section (b) of figure 1. The conversion of the rotation of the rotatable
member 6 into movement of the point Q relative to the centre axis V can be carried
out by an arrangement of mechanical parts such as gears and rods comprised by the
adjustment means 5. Examples are spur gear, bevel gears, helical gears, planet gears,
worm gears, toothed rods, key-keyway connections, springs, screws, etc. The rotation
of the rotatable member 6 can be provided by a user interaction, for instance by a
screwdriver being turned in a notch 23 comprised by the rotatable member 6. The rotation
can also be effected by other tools, or a finger screw, or even by automatic means
such as an electrical motor (not shown).
[0036] Fig. 2 shows a schematic view of a preferred embodiment of a mounting device 1 according
to the invention used for a lighting fixture 2 suspended from above. In this embodiment,
the adjustments means 5 comprises a first rotatable member 9 which engages a second
rotatable member 10. The second rotatable member 10 is connected to the suspension
means 3 by a spherical member 7 being attached to the end of the suspension means
3. The spherical member 7 is housed in a cavity of the second rotatable member 10,
whereby the suspension point Q moves along with the second rotatable member 10. In
the preferred embodiment shown in figure 2, the first rotatable member 9 comprises
a helical thread 12 extending radially from the rotatable member's 9 axis of rotation
15. The second rotatable member 10 shown in figure 2 comprises a set of gear teeth
13 extending radially from its axis of rotation 15', and the leading edges 14 of these
gear teeth 13 are parallel to the axis of rotation 15' of the second rotatable member
10. The gear teeth 13 only cover a segment of the rotatable 10, making room for the
cavity housing the spherical member 7. In the preferred embodiment of the invention
shown in figure 2, the axes of rotation 15,15' of the first and the second rotatable
members 9,10 are orthogonal to each other, whereby the two rotatable members 9,10
essentially form a worm gear. This means that when the first rotatable member 9 carry
out one rotation, the second rotatable member 10 is rotated what is equal to one of
the gear teeth 13. In the example shown in figure 2, one rotation of the first rotatable
member 9 effects a rotation of a little less than 13 degrees of the second rotatable
member 10, which causes a small movement of the suspension point Q relative to the
centre axis V of the lighting fixture 2, which in turn causes an adjustment of the
inclination α of a little less than 3 degrees. As indicated in figure 2, the first
rotatable member is rotated until resulting the movement of the suspension point Q
has caused an adjustment of the lighting fixture's 2 inclination α to the vertical
in section (a) of figure 2 to zero in section (b) of figure 2. The amount of gear
teeth 13, the inclination of the helical thread 12 and the dimensions of the rotatable
members can of course be modified to provide a larger or smaller degree of adjustment
of the inclination per rotation of the first rotatable member 9. In most situations,
an adjustment of the inclination α of less than 10 degrees per rotation of the first
rotatable member 9 is reasonable, and an adjustment of the inclination α of less than
3 degrees per rotation of the first rotatable member 9 is usually preferred to provide
the required precision in the inclination adjustment. To sum up, the preferred embodiment
shown in figure 2 provides a step-less adjustment of the lighting fixture's 2 inclination
α to the vertical. Also, the adjustment provided can be carried out at a very detailed
level while the lighting fixture 2 is suspended from above, so it is not necessary
to take it down if adjustment is needed. Furthermore, since the rotation of the first
rotatable member 9 can be easily carried out, for instance by means of a screwdriver,
the adjustment is easy and fast to perform. Finally, since the adjustment means 5
only comprises a few members, all of them being relatively simple components, the
mounting device 1 provided by the invention is small and cheap to manufacture.
[0037] In figure 3 is shown a top view (section (b)) and a side view (section (a)) of an
alternative preferred embodiment of a mounting device 1 according to the invention.
In this alternative preferred embodiment, the suspension means 3 is an electric cable,
meaning that the suspension means 3 apart from providing suspension also provides
electricity to the lighting fixture 2. As indicated in section (a) of figure 3, the
suspension means 3 is thus connected to the connection means 4 in a suspension point
Q somewhere along its middle section. Furthermore, the end of the suspension means
3 can be located in a fixing point R in which the electrical connection between the
suspension means and a light source (not shown) comprised by the lighting fixture
can be established. Once the suspension means 3 is connected to the lighting fixture
in the points Q and R, the adjustment of the lighting fixture's inclination α can
be adjusted by rotation of a rotatable member 6, as in accordance to the invention.
[0038] Fig. 4 shows a schematic view of an alternative preferred embodiment of a mounting
device 1 according to the invention, in which the adjustment means 5 comprises a rotatable
member 6 comprising a helical thread 12. The axis of rotation 15 of the rotatable
member 6 is essentially orthogonal to the centre axis V of the lighting fixture 2.
The rotatable member 6 is in one end connected to the mounting device 1 in a rotatable
joint 24, and in another end connected to the mounting device 1 in a rotatable joint
25, which enables the rotatable member 6 to rotate without moving relative to the
mounting device 1. The suspension means 3 is in a suspension point Q connected to
a threaded member 8 acting as connection means 4. The threaded member 8 comprises
an internal thread mirroring the helical thread 12 of the rotatable member 6. The
threaded member 8 engages the rotatable member 6 via the matching threads. In this
way, rotation of the rotatable member 6 causes the threaded member to translate along
the axis of rotation 15 of the rotatable member. This in turn makes the suspension
point Q move relative to the centre axis V of the lighting fixture 2, and an adjustment
of the lighting fixture's 2 inclination α to the vertical is achieved. One advantage
of this alternative embodiment is that the rotatable member 6 can be reached by a
user from the side, which may be preferable in some situations. Also, this embodiment
provides an easy, simple and cheap to manufacture adjustment of the lighting fixture's
2 inclination α to the vertical. By having a very low inclination of the helical thread
12, a very detailed adjustment can be provided.
[0039] Fig. 5 shows a schematic view of a variation of the alternative preferred embodiment
of a mounting device according to the invention shown in figure 4. Here, the second
rotatable member (in figure 5 denoted 10, in figure 4 denoted 6) comprising the helical
thread 12 and engaging the connection means 4,8 has a bevel gear 17 in its second
end. This bevel gear 17 engages a second bevel gear 17' which is connected to one
end of a first rotatable member 9. The rotational axis 15 of the second rotatable
member 10 is essentially orthogonal to the rotational axis 15' of the first rotatable
member 9. This enables a user to rotate the first rotatable member 9 by engaging it
with for instance a screwdriver from above. Hence, the alternative preferred embodiment
shown in figure 5 provide the same advantages as those shown in figure 4, apart from
the feature that a user can effect the adjustment from the top of the mounting device
1 instead of from the side of the mounting device 1.
[0040] Fig. 6 shows a schematic view of another alternative preferred embodiment of a mounting
device 1 according to the invention comprising a toothed rod 20, i.e. a rod comprising
a linear rack of gear teeth. The suspension means 3 is in a suspension point Q connected
to a spherical member 7, which acts as connection member 4. The spherical member 4,7
is connected to the toothed rod 20. A rotatable member 6 comprising gear teeth 13
comprising leading edges 14 parallel to its axis of rotation 15, which is essentially
parallel to the centre axis V of the lighting fixture 2. The gear teeth 13 engage
the linear rack of teeth of the toothed rod 20 in such a manner that rotation of the
rotatable member 6 causes the toothed rod 20 to translate orthogonally to the axis
of rotation 15, whereby the suspension point Q is moved relative to the centre axis
V of the lighting fixture 2, thus adjusting the inclination α of the lighting fixture
2 to the vertical.
[0041] Fig. 7 shows a schematic view of another alternative preferred embodiment of a mounting
device 1 according to the invention comprising a glider 21, which comprises an internal
helical thread, a surface 26 and a groove. The suspension means 3 is in a suspension
point Q connected to a spherical member 7, which acts as connection member 4. The
suspension means 3 passes through the groove comprised by the glider 21 in such a
manner that the spherical member 7 locks it in position by the aid of gravity. A rotatable
member 6 comprising a helical thread 12, mirroring the internal thread of the glider
21, and an axis of rotation 15, which is essentially parallel to the centre axis V
of the lighting fixture 2. The rotatable member 6 engages the glider 21 by engagement
of the mirroring threads, whereby rotation of the rotatable member 6 causes the glider
to translate along the centre axis V of the lighting fixture 2. The surface 26 is
flat with an angle to the centre axis V of the lighting fixture 2, whereby the glider's
translation causes the suspension point Q to move relative to the centre axis V of
the lighting fixture and the inclination α is adjusted.
[0042] Fig. 8 shows a schematic view of another alternative preferred embodiment of a mounting
device 1 according to the invention, comprising a rotatable member 6 comprising a
helical thread 12. The mounting device comprises a groove 27 which in one end comprises
an internal helical thread 28, mirroring the helical thread 12 of the rotatable member
6. The suspension means 3 is in a suspension point Q connected to a spherical member
7, which acts as connection member 4. The spherical member 7 is housed in the groove
27 in such a manner that rotation of the rotatable member 6 causes it to translate
in the groove 27, whereby the suspension point Q moves relative to the centre axis
V of the lighting fixture 2. Thus, rotation of the rotatable member 6 causes an adjustment
of the inclination α of the lighting fixture 2 to the vertical.
[0043] In yet another alternative preferred embodiment of the invention, the adjustment
of the inclination α of the lighting fixture to the vertical can happen in steps.
This can for instance be achieved by integrating dents in the threads or gear teeth
of the rotatable members.
[0044] The person skilled in the art will understand that other combinations of mechanical
components than those exemplified in the above to achieve conversion of rotation of
a rotatable member to adjust inclination to the vertical can be used to make a mounting
device in accordance to the invention.
[0045] It is obvious for a person skilled in the art, that a mounting device according to
the invention can be used for other objects suspended from above, such as ornaments,
sensors, electronics, etc., where a need for detailed adjustment is present. Also,
a person skilled in the art will understand that a mounting device according to the
invention can be used with suspension means such as a rod, a chain, a rope, a cable,
an electric cable, a wire, a tube or any other suitable suspension means.
