Definitions
- the present invention relates to the technical field of light fittings and to lamps in general. More specifically, the present invention relates to a light fitting for attaching a lamp to a ceiling, to a lamp comprising such a light fitting and to a method for attaching a light fitting to a ceiling.
- Light fittings are well known products used for instance for attaching lamps to ceilings. They usually comprise both electrical connections as well as some sort of means for supporting the weight of the lamp, which in some cases is the electrical cord and in some cases is a separate wire or similar. As light fittings are often visibly mounted to a ceiling, they are preferably designed to be aesthetically pleasing and they may for this reason comprise covers or ceiling roses which cover the interior components of the light fitting.
- Light fittings which are configured to attach a lamp to a ceiling may be configured to be attached to the ceiling in a number of ways. Commonly used methods include screws and hooks which are pre-mounted to the ceiling, to name a few. It is a common problem when mounting pendant lamps that it is difficult to achieve a desired hanging height of the lamp, as this often requires the person hanging the lamp having to tediously adjust the length of the cord/wire which attaches the lamp to the light fitting. Access to the internal components of the light fitting such as the electrical connectors and/or the means for hanging the light fitting may also be limited.
- a light fitting for attaching a pendant lamp to a ceiling comprises a first member attachable to the ceiling and a second member. A first end of said second member is connected to the first member and a second end is connected directly or indirectly to the lamp, such that the second end protrudes outside, or out of, the first member in a direction towards the pendant lamp.
- the length of the part of the second member protruding outside the first member is adjustable. In some embodiments the hanging height of the lamp is thus conveniently adjustable by altering the second member protrusion length. In other embodiments, adjustment of the length of the part of the second member protruding outside the first member allows for easy access when mounting the lamp.
- the light fitting further comprises a housing member configured to at least partly cover the first member.
- the housing member comprises a first hole through which the second member extends.
- the adjustable length of protrusion of the second member facilitates mounting of the housing member as well as simplifies access to the parts of the light fitting that are configured to be covered by the housing member.
- the first hole of the housing member may be configured to be essentially axially aligned with the first member.
- the first member may comprise a thread and the light fitting further comprises a nut through which the second member extends and which is configured to engage with the thread of the first member.
- the nut is axially moveable relative the second member and rotatable in relation to the light fitting.
- the nut may comprise a flange configured to vertically support the housing member. As the second member is moveable in relation to the nut and the housing member that the nut supports, access during mounting is improved even when the housing member is mounted to the light fitting.
- the second member is a wire.
- the first member may be provided with a lock member configured to allow unrestricted movement of the wire in a direction towards the first member and to restrict, or even prevent, movement of the wire in a direction away from the first member. A safe adjustability of the length of wire protrusion is thus provided.
- Unwanted extension of the wire is avoided, as the lock member must be actively released, e.g. by depressing a lock release member, for extension of the wire to occur.
- the lock member is arranged concentrically around the wire.
- the second member is an elongated hook.
- the hook may be configured to, in a first rotational position in relation to the first member, allow for a first extension of the hook out of the first member and in a second rotational position in relation to the first member allow for a second extension of the hook outside, or out of, the first member.
- the first extension is larger, or longer, than the second extension. The length of hook protrusion is thus determined by the rotational position of the hook in relation to the first member.
- first rotational position and the second rotational positions are offset by approximately 90° in relation to each other.
- the hook at its first end comprises a pin protruding from at least one side of the hook in a direction essentially perpendicular to the extension of the hook.
- the pin is arranged diametrically trough the hook.
- the pin may be configured to be vertically moveable in at least one vertical slit provided in the first member.
- the slit is limited by a slit stop arranged in a first end of the slit and defining the length of the first extension of the hook.
- the pin can be rotated in one or more recesses arranged in a second end of the slit to engage with a shelf arranged in the second end of the slit, the shelf defining the length of the second extension of the hook.
- Each shelf may comprise a shelf stop that requires the hook to be further inserted into the first member to allow rotation into and out of the first rotational position.
- a lamp for attachment to a ceiling, the lamp comprises a light fitting according to the first aspect.
- a method for mounting the light fitting according to the first aspect to a ceiling comprises the steps of: attaching the first member of the light fitting to the ceiling and adjusting the length of a part of the second member protruding out of the first member.
- the hanging height of the lamp attached to the light fitting can thereby be altered after it is mounted to the ceiling.
- the protrusion may also be altered when the light fitting is not yet mounted to the ceiling.
- the method for mounting the lamp comprises the steps of: adjusting the length of a part of the second member protruding out of the first member to facilitate access to the first member, attaching the first member of the light fitting to the ceiling, attaching the nut to the first member and thereby attaching the housing member to the first member and adjusting the length of a part of the second member protruding out of the first member to a desired length.
- the method for mounting the light fitting comprises the steps of: adjusting the length of a part of the wire protruding out of the first member by unlocking the lock member to allow for an extension of the wire to a length facilitating access to the first member, attaching the first member of the light fitting to the ceiling, attaching the nut to the first member and thereby attaching the housing member to the first member and adjusting the length of a part of the wire protruding out of the first member to a desired length by feeding the wire towards the first member.
- the method for mounting the light fitting comprises the steps of: adjusting the length of a part of the hook protruding out of the first member by rotating the hook to the first rotational position to allow for an extension of the hook to a length facilitating access to the first member, attaching the first member of the light fitting to the ceiling, attaching the nut to the first member and thereby attaching the housing member to the first member and adjusting the length of a part of the hook protruding out of the first member to a desired length by feeding the hook towards the first member and the rotating it into the second rotational position.

- the lamps 30, 40 are typically hanged from a ceiling by means of a first member 11, 21 (Figs. 3 and 9, respectively) of an associated light fitting 10, 20 which is most often included when purchasing the lamp 30, 40.
- a housing member 13, 23 i.e. a ceiling rose
- the light fitting 10, 20 further comprises a second member 12, 22 that is configured to connect directly or indirectly to the lamp 30, 40.
- the second member 12 is a wire 12 which extends from the ceiling the entire way down to the lamp 30.
- the second member 22 has the shape of an elongated hook 22.
- the lamp 40 then connects indirectly to the hook 22 via a chain 41.
- the second member 12, 22 is different from the power cord PC.
- the light fitting 10, 20 is also supporting a power cord PC being separate from the second member 12, 22.
- the light fitting 10 is shown without the housing member 13.
- the light fitting 10 comprises the first member 11 that serves as the part of the fitting 10 that is attachable to the ceiling.
- a ceiling hook CH is attached to the ceiling and the first member 11 comprises a loop 114 that attaches to the hook CH.
- Other means for attaching the first member 11 to the ceiling are also conceivable.
- the first member 11 further comprises a lock member 111 in the shape of a wire lock 113, having a resilient button 11 la which when depressed allows the second member 12 to move both away from the first member 11, meaning downwards as illustrated in Fig. 3, as well as towards it, meaning upwards as illustrated in Fig. 3, by sliding through the lock member 111 and into the first member 11.
- the second member 12 When the lock member 111 is in a non-depressed state, the second member 12 is still moveable but only in a direction towards the first member 11, i.e. upwards as illustrated in Fig. 3. This results in a solution where the person hanging a lamp using the light fitting 10 described herein can simply extend the second member 12 fully when hanging the lamp to the ceiling and then simply raise the lamp to a desired height while feeding the second member 12 into the first member 11. The first member 11 will then support the lamp at this new and desired height.
- Fig. 4 an embodiment of the light fitting 10 is shown where also the electrical wirings are shown and it is shown how a connection box 115 may attach to the first member 11.
- the electrical wiring of the light fitting 10 is not a central part of the inventive concept and may be achieved in a number of ways. For instance, electrical connectors may be integrated into the first member 11 or be provided as a separate part, which is then attached to the first member 11 or hanged separately from the ceiling.
- the first member 11 shown in Figs. 3 and 4 further has a cylindrical body 116 being provided with an external thread 112, the purpose of which becomes apparent when turning to Fig. 5.
- the first member 11 and a part of the second member 12 are covered by a housing member 13.
- the housing member 13 sometimes called a ceiling rose, protects the other components of the light fitting 10 as well as provides a more aesthetically pleasing appearance of the lamp as a whole.
- the housing member 13 is attached to the first member 11 by means of a nut 14, which is configured to engage with the thread 112 of the first member 11 shown in Figs. 3 and 4.
- the nut 14 comprises a flange 141, clearly shown in Fig. 8.
- the flange 141 supports the housing member 13 vertically.
- Both the nut 14 and the housing member 13 comprise axially aligned holes 131 which allow the second member 12 to move in relation to the nut 14 and the housing member 13 and vice versa.
- the length of a part of the second member 12 protruding out of the first member 11 is adjustable also when the lamp 30 is completely assembled and mounted to the ceiling. In case the lamp 30 is to be lowered then the resilient button 11 la of the lock member 111 has to be depressed.
- the housing member 13 may comprise a second hole 132 through which the electrical power cord PC may extend.
- Fig. 7 the procedure for extending the length of a part of the second member 12 protruding out of the first member 11 is shown.
- the wire lock 113 forming the lock member 111, must be maneuvered, in this case by depressing the resilient button 11 la, meaning pushing upwards as shown in Fig. 7, to unlock the lock member 111, i.e. the wire lock, to make it possible to move the second member 12 out of the first member 11, i.e. downwards as shown in Fig. 7, for a lowered position of the lamp.
- the light fitting 10 is shown in a cross-sectioned view such that the internal components of the first member 11 are visible.
- the first member 11 is provided with the lock member 111 in the form of a wire lock 113.
- the wire lock 113 is spring loaded and self-locking for withdrawing of the second member 12 out of the first member 11.
- the resilient button 11 la forms part of the wire lock 113 such that when depressed it pushes against the force of the spring and thereby releases the locking engagement of the wire lock 113 on the second member 12.
- the wire lock 113 is per se a conventional item that is known to the person skilled in the art; it could be constructed in a plurality of ways to achieve the desired functionality.
- lock member 111 may be arranged such that it is accessible even when the nut 14 and the housing member 13 are attached to the first member 11. This allows the second member 12 to be extended out of the first member 11 also when the nut 14 and the housing member 13 are attached, further simplifying adjustment of the height of the lamp 30.
- the light fitting 20 of Fig. 9 comprises a first member 21 that is configured to be attached to the ceiling.
- the following description of embodiments will focus mainly on the features that differs from the embodiments described earlier as many features and functions are common for the embodiments.
- the light fitting 20 comprises a second member 22 in the form of an elongated hook 22.
- the second member 22 is attached to the first member 21 such that the length of a part of the hook 22 protruding out of the first member 21 can be adjusted.
- the first member 21 is provided with threads 212 that are configured to engage with corresponding internal threads of a nut 24.
- the purpose and function of the nut 24 are the same as described for the previous embodiments and will thus not be described in further detail.
- the light fitting 20 is provided with a housing member 23.
- the housing member 23 comprises a first hole 231 into which the nut 24 fits to hold the housing member 23 in place.
- a second hole 232 may also be provided, through which an electrical cord may be inserted.
- the second member 22 comprises a pin 222 arranged at a first end 221 of the second member 22.
- the pin 222 is arranged diametrically through the second member 22 and protrudes outwards on opposing sides of the second member 22, forming an essentially T-shaped first end 221. This is shown in Fig. l2a, and especially also in Fig. l2b showing an enlarged section of the first end 221 of the second member 22.
- the pin 222 is configured to cooperate with an interior of the first member 21, shown in Fig. 11.
- the first member 21 is provided with at least one, and preferably two, vertically extending slits 216, which are formed radially outwardly from the central hole 218 in the first member 21.
- the second member 22 can be moved vertically in the central hole 218.
- the pin 222 slides in the slits 216, allowing axial motion of the second member 22 limited downwardly by a slit stop 213 which defines the first, maximum, protrusive length of the second member 22.
- This first protrusive length of the second member 22, being the maximum length that the second member 22 can extend out of the first member 21, would typically be used when mounting the light fitting 20 to the ceiling. So this first protrusive length of the second member 22 would be the“mounting position”.
- the second member 22 For the pin 222 to be able to enter the slits 216, the second member 22 must be rotated into a first rotational position where the pin 222 is aligned with the slits 216.
- recesses 214 are provided in order to lock the second member 22 at a second protrusive position that corresponds to an inserted position, i.e. a shorter length of the part of the hook 22 protruding outside the first member 21, recesses 214 are provided.
- the second protrusive length of the second member 22, being the minimum length that the second member 22 can extend out of the first member 21, would typically be used after the light fitting 20 has been mounted to the ceiling and the lamp is ready for use. So this second protrusive length of the second member 22 would be the normal“in-use position”.
- the recesses 214 are arranged at the upper portion of the first member 21 and are mirrored essentially in the cross-sectional plane as illustrated in Fig. 11.
- the second member 22 is rotated into a second position in relation to the first member 21, whereby the pin 222 enters the recesses 214 and the second member 22 is thereby supported vertically by the interaction between the pin 222 and respective shelves 217 arranged at a lower end of the recesses 214.
- Shelf stops 215 may be provided which prevent the second member 22 from unintentional rotation by which the pin 222 leaves the shelves 217 and falls out of the recesses 214 and down to the slit stop 213.
- each shelf 217 may be slightly inclined such that the pin 222 slides into the vertically lowest position in the recess 214. This will also aid in securing the second member 22 in the second rotational position.
- the first and second rotational positions are separated or offset by approximately 90°.
- Figs. l4a-b the process of reducing the length of the part of the second member 22 protruding out of the first member 21 is shown. It is beneficial if the second member 22 is kept at maximum extended length while mounting the light fitting 20 to the ceiling, because this will facilitate access to the components that otherwise are to be hidden by the housing member 23.
- Fig. l4a-b the process of reducing the length of the part of the second member 22 protruding out of the first member 21 is shown. It is beneficial if the second member 22 is kept at maximum extended length while mounting the light fitting 20 to the ceiling, because this will facilitate access to the components that otherwise are to be hidden by the housing member 23.
- the second member 22 is shown when protruding a maximum distance dl out of the first member 21 (the first member being hidden by housing member 23). Afterwards, when the first member 21 is attached to the ceiling and the electrical wiring is done, the housing member 23 may be attached at its preferred height using the nut 24. Then, as indicated in Fig. l4b, the second member 22 is simply pushed upwards, towards the first member 21. When the pin 222 arranged in the first end 221 reaches the recesses 214, the second member 22 is free to be rotated into the second rotational position whereby the second member 22 is supported vertically, by the pin 222 resting on the shelves 217 arranged in the recesses 214.
- the second member 22 is held in place with a reduced length of protrusion out of the first member 21, indicated by distance d2.
- the chain is used, and a desired height of the lamp is achieved by hanging a suitable link of the chain to the end of the hook 22, as is per se known.
- Fig. 15 an outline of a method for mounting the light fitting 10, 20 to a ceiling is shown.
- the method comprises the step 101 of attaching the first member 11, 21 of the light fitting 10, 20 to the ceiling followed by a step 102 of adjusting the length of a part of the second member 12, 22 protruding out of the first member 11, 21.
- Fig. 16 the outline of a further embodiment of a method for mounting a light fitting to a ceiling is shown.
- the method shown in Fig. 16 comprises the step 201 of adjusting the length of a part of the second member 12, 22 protruding out of the first member 11, 21 to facilitate access to the first member 11, 21. 1.e. in step 201 the second member 22 is extended to the maximum or preferred length.
- a subsequent step 202 the first member 11, 21 of the light fitting 10, 20 is attached to the ceiling, after which a step 203 is performed in which the nut 14, 24 is attached to the first member 11, 21.
- the housing member 13, 23 is attached to the first member 11, 21 and secures the light fitting 10, 20 against the ceiling.
- a method for mounting the light fitting of the embodiments shown in Figs. 1 and 3-8 a step 301 is performed in which the length of the wire 12 protruding out of the first member 11 is adjusted by unlocking the lock member 111 to allow extension to a length facilitating access to the first member 11.
- the length of the wire 12 protruding out of the first member 11 could be extended to a maximum length or any given length that is considered sufficient.
- the first member 11 may then be attached to the ceiling in step 302. Note that these two first steps may just as well be performed in the opposite order, i.e.
- the wire 12 may just as well be extended when the light fitting 10 is hanging from the ceiling.
- the nut 14 is attached to the first member 11 in step 303.
- the housing member 13 is pressed upwards against the ceiling, which secures the light fitting 10.
- the length of the wire 12 protruding out of the first member 11 can be adjusted to a desired length in step 304. This is done by simply lifting the lamp and feeding the wire 12 towards and into the first member 11.
- the wire lock 113 of the first member 11 will allow the wire 12 to travel in an upward direction, but as soon as a downward force is applied on the wire 12 it will lock automatically.
- the lock member 111 may be maneuverable also after that the nut 14 is attached to the first member 11. This would allow extension of the wire 12 even when the housing member 13 is mounted to the ceiling.
- a method for mounting the light fitting 20 of the embodiments in Figs. 2 and 9-14 is shown. Firstly, in step 401 the length of a part of the hook 22 extending outside the first member 21 is adjusted by rotating the hook 22 to the first rotational position to allow extension to a length facilitating access to the first member 21. In this position the pin 222 of the hook 22 rests on the slit stops 213 illustrated in
- the extension of the hook 22 allows the housing member 23 to move away from the first member 21, and this simplifies the mounting of the first member 21 to the ceiling as well as any other installation task that might be necessary.
- the first member 21 is attached to the ceiling by e.g. hanging it from a pre-mounted ceiling hook or using screws or other means for securing it to the ceiling.
