Definitions

  • the present invention relates to a floor lamp with a pillar and a lamp head held at the upper end of the pillar, with the possibility of adjusting the orientation of the lamp head.
  • Floor lamps of the present type are used in particular to illuminate workplaces, for example to illuminate office workplaces. Compared to lights attached to ceilings or other suspension elements, floor lamps can be positioned relatively easily and flexibly so that they can be appropriately assigned to a workspace, e.g. a desk, in order to illuminate it efficiently. Even when redesigning an office, the lighting can be adjusted in this way in a simple manner.
  • such floor lamps typically have a substantially vertically extending column, which extends upwards from a lower lamp base.
  • the actual light emission takes place at the upper end of the column with the help of a so-called lamp head, for which different embodiments are known.
  • this is a large-area, e.g. rectangular element, which is attached to the column on one side and then emits the light via a lower light exit area.
  • the optimal illumination of a workplace with the help of a floor lamp is primarily ensured by the fact that the lamp is positioned in a suitable manner with regard to the workplace. This position should be selected according to the shape and size of the workplace and taking into account the light distribution of the light emitted by the lamp.
  • the DE 20 2005 010313 U1 describes a floor lamp in which the lamp head is mounted with difficulty relative to a vertical column in order to be able to transfer it from a transport position into an operating position. The lamp head is then locked in a horizontal position suitable for use by means of several screws.
  • the U.S. 2012/294004 A1 describes a ball joint for arranging a lamp head on a holder provided for this, so that the lamp head is movably mounted.
  • the object of the present invention is therefore to provide a solution that is as simple as possible and that allows the alignment of a lamp head of a floor lamp to be adjusted.
  • the pivot axis is fixed by the interaction between the recesses and the support element, so that a defined adjustment of the alignment of the lamp head is made possible without sensitive components of the lamp being deformed or subjected to excessive stress in such a way that damage is to be feared.
  • the recesses have a curved shape, preferably the shape of a segment of a circle.
  • the column is formed by an elongate profile part with a preferably rectangular cross section, the profile part then having recesses according to the invention on two opposite side walls, which form the receptacle for the lamp head.
  • the adjustment means comprise a screw connection positioned offset to the pivot axis. Since the column is formed by a profile part, it is provided according to the invention that this profile part has a screw channel which extends in the vertical direction and is particularly preferably provided with a corresponding thread. This measure can also be implemented without additional components of the lamp, so that the concept according to the invention does not lead to an increase in the number of components required.
  • the lamp head has, for example, a pot-like receiving area that overlaps the upper end of the column. It can be provided in particular that the receiving area of the lamp head is designed to widen in the direction of the column, preferably so that it widens conically. This provides a certain amount of play, which allows the alignment of the lamp head to be adjusted accordingly without undesired deformation of certain components.
  • the luminaire has means for limiting of the swivel range for the lamp head.
  • This can in particular be a stop element which is arranged on the column and which, according to a particularly preferred embodiment, is designed to be adjustable.
  • the stop element can be formed, for example, by an additional screw arranged on the column. Depending on the positioning of this screw, the range over which the alignment of the lamp head can be adjusted is correspondingly limited. At the same time, this also ensures stable storage or mounting of the lamp head on the column.
  • the lamp head itself can be designed in different ways. It preferably has a carrier element extending transversely to the column, which is mounted on the column in the manner according to the invention and on which the means for generating and emitting light are preferably arranged in the form of exchangeable or at least detachable components.
  • the support element can be elongate, in which case means for generating and emitting light are arranged on both sides of the support element.
  • a further advantage of the mounting of the lamp head on the column according to the invention is that this opens up the possibility of providing a continuously extending channel for mounting a cable for the power supply of the lamps. This extends through the column and the mount to the area of the lamp head, without the cable having to be routed laterally past the components of the lamp. This measure contributes to an improved appearance of the lamp, with the advantages in terms of the adjustability of the lamp head being retained in spite of everything.
  • FIG 1 shows a perspective view of a floor lamp, generally provided with the reference numeral 100, which is designed in a manner according to the invention and thus enables the lamp head to be aligned with respect to a pivot axis which runs essentially horizontally.
  • the floor lamp 100 shown has, among other things, a vertically extending column 10 as essential components, at the upper end of which the lamp head 30 is arranged, which extends transversely to the column 10 .
  • the lower end of the column 10 is anchored to a lamp base 5, which provides a wide base and thus enables the lamp 100 to be positioned stably on a substrate.
  • the shape of the lamp base 5 could also be designed differently. Direct anchoring of the column 10 in a floor area using suitable fastening measures would also be conceivable in principle.
  • the lamp head 30 is elongate and rectangular in shape, although of course the invention is not limited to the configuration shown and the lamp head can also have a different shape.
  • the manner in which the light generated by the lighting means is emitted towards the underside and/or towards the upper side is also irrelevant for the present invention.
  • the present invention includes all such variants, which is why these means for generating and emitting light are not explained further below.
  • the lamp head 30 is arranged and mounted on the upper end of the column 10 in the manner described in more detail below according to the invention in such a way that its alignment with respect to the horizontal can be adjusted.
  • the concept according to the invention is implemented in a manner that does not require the use of additional components.
  • the mounting of the lamp head 30 on the column 10 according to the invention is achieved by a corresponding design of these components that are available anyway, so that the number of components is not additionally increased by the possibility of adjusting the alignment of the lamp head 30 .
  • figure 2 shows here first the upper end of the column 10, which is designed in a manner according to the invention.
  • the column 10 is designed in the form of an elongate profile part and can be formed, for example, by an aluminum extruded profile.
  • a rectangular cross-sectional shape is selected for the column 10, although other cross-sectional shapes would of course also be conceivable.
  • the profile part 15 forming the column 10 therefore initially has four side walls 16, 17, 18 and 19, with a transverse web 20 connecting the two walls 16 and 17 also being provided.
  • This serves not only to increase the stability of the column 10 as a whole, but also has a channel 21 that extends in the longitudinal direction of the column 10, i.e. vertically, which forms a screw channel, as explained in more detail below, with the help of which the lamp head 30 in the desired orientation or pivoting position on the column 10 is locked.
  • Another channel 22 is also formed on the rear side wall 19, which serves to accommodate the stop element, which will be described in more detail later, with the aid of which the range over which the inclination of the lamp head 30 can be adjusted is limited.
  • the recesses 25 and 26 are two opposite recesses 25 and 26 on the walls 16 and 17. In the case shown, these have the shape of a segment of a circle, with a horizontal axis then running through the respective centers of the corresponding circles I is defined, which forms a pivot axis about which the lamp head 30 is adjustable.
  • the recesses 25 and 26 can then be created in a simple additional work step, for example by appropriate milling or drilling of the profile part 15 .
  • the central element of the lamp head 30 is in the Figures 3 to 5 shown carrier element 40, which has at one end a fastening area 41 designed according to the invention, from which an elongate web 42 extends.
  • carrier element 40 which can be realized for example in the form of an aluminum die-cast part, then as already mentioned attached to the actual means for generating and emitting light, which, however, can be designed in a wide variety of ways and do not play a significant role in the present invention.
  • the design of the carrier element 40, in particular of the rear fastening area 41, which is responsible for the arrangement and mounting of the lamp head 30 on the column 10, is decisive for the solution according to the invention.
  • the fastening area 41 of the carrier element 40 has a downwardly open, cup-like receiving area 45 delimited by four side walls 46 - 49 and a horizontally extending wall 55, which when the lamp head 30 is mounted on the column 10 in such a way that it upper end of the column 10 is placed in such a way that the side walls 46 - 49 overlap the end area of the column 10 accordingly.
  • the pivotable mounting of the carrier element 40 on the column 10 is made possible in that on the insides of the side walls 46 and 47 of the receiving area 45 projections 50 - in figure 5 only the projection 50 of the wall 47 can be seen here - are formed, the lower end of which has at least the shape of a segment of a circle, which corresponds to that of the recesses 25 and 26 of the column 10.
  • these projections 50 engage in the corresponding recesses 25 and 26, so that the lamp head 30 can be pivoted about the axis I.
  • at least the side walls 48 and 49 are designed to widen slightly downwards, in particular to widen slightly conically.
  • the carrier part 40 has a completely from the side wall 46 to the opposite side wall 47 extending, for example.
  • the shape shown with two spaced-apart projections 50 has the additional advantage that an in-between figure 5 recognizable passage opening 51 can be created in the horizontally extending wall 55, which allows the passage of a power supply cable extending through the column 10 to the upper end area.
  • This cable which is not shown in the figures, is then routed further through the opening 51 into the lamp head 30 in order to supply the corresponding lamps or possibly suitable control gear for operating the lamps with electricity.
  • a solution for storing the cable that is integrated over the entire length of the cable is created so that it is permanently well protected from external influences.
  • the inventive storage of the support member 40 on the column 10 is in the sectional view of figure 6 recognizable. It is also shown here again that the receiving area 45 of the support part 40 has the already mentioned, horizontally extending wall 55, in which the just mentioned opening 51 is formed and which, when the lamp head 30 is placed on the column 10, at least partially on the upper edges the walls of the profile part 15 rests.
  • a second screw 62 screwed into the further channel 22 is used here as a rear stop element, with the aid of which the range over which the inclination setting can be adjusted is limited.
  • This further screw 62 does not pass through the horizontal wall 55 of the carrier part 40, but is accessible again via a corresponding opening 57 in the wall 55 and its position can be adjusted with a corresponding tool. So it is not used for the actual attachment of the lamp head 30 to the column 10 but, as already mentioned, only to form a height-adjustable support point for the rear end area of the carrier part 40, so that the area of the inclination adjustment is defined accordingly. If necessary, however, this further screw 62 or an adjustable stop element designed in a different way could also be dispensed with.
  • both screw channels 21 and 22 each preferably have an internal thread.
  • the introduction of threads in both screw channels 21 and 22 has the advantage that a consistently stable connection is guaranteed, even if the screws 60 or 62 are screwed in and out several times. This also ensures that the respective screw 60 or 62 can be screwed in more or less exactly in the direction of the screw channel 21 or 22 - without angle errors occurring, e.g. due to careless screwing in.
  • figure 7 an essentially right-angled alignment of the lamp head 30 with respect to the vertical longitudinal axis of the column 10 is provided.
  • figure 8 1 shows a state in which both screws 60 and 62 have been screwed somewhat further into the associated channels 21 and 22, so that the rear area 41 of the carrier part 40 is pulled slightly downwards in relation to the pivot axis I. This in turn means that the front area of the lamp head 30 is tilted by the angle ⁇ (see figure 8 ) swiveled slightly upwards is aligned. It can thus be seen that the inclination of the lamp head 30 can be adjusted very easily and quickly within certain limits with the aid of the screws 60 and 62 and the bearing according to the invention.
  • the final assembly of the lamp 100 at the customer is then carried out in that the lamp head 30 , in particular the support part 40 , is placed on the upper end area of the column 10 .
  • the screw 62 is already screwed into the channel 22 of the column 10 here. It is then only necessary to screw in the screw 60 that is mainly responsible for the attachment and selection of the inclination, so that the assembly of the lamp 100 including the adjustment of the inclination of the lamp head 30 can be carried out in a very simple and convenient manner. If need be, the position of the screw 62 still needs to be adjusted in order to be able to achieve a stable support of the lamp head 30 on the column 10 .
  • a floor lamp can be made available that enables the lamp head to be precisely aligned and locked in a desired position.
  • An advantage of the solution according to the invention is that, as can be seen from the above explanations, the concept according to the invention can be implemented by appropriately adapting the components of the lamp that are already present anyway. In particular, no additional components are required, which would lead to increased complexity in production and thus to greater costs.
