Definitions
- the present invention relates to a luminaire with a fastening element for fastening light influencing means to a carrier element.
- a support element When installing lights, a support element is often attached to the ceiling or other suspension device in a first step.
- This carrier element forms the basic structure of the lamp and is used, for example, to hold the lamp and a corresponding control device for operating this lamp.
- further light influencing means are then attached to the carrier element, for example reflectors, grids or diffusers.
- a lamp which has the features of claim 1.
- This lamp consists of a carrier element for an elongated lamp, elongated light influencing means to be fastened to the carrier element and at least one fastening element provided on the light influencing means and longitudinally displaceable between a locking position and an unlocking position, which has locking projections which engage in locking recesses of the carrier element in the locking position of the fastening element and thereby fix the light influencing means to the carrier element.
- At least one deflectable spring arm is provided on the or each fastening element, which spring arm has a latching lug directed against the carrier element and forming the latching projection.
- the spring arm also contains an inclined ramp, which cooperates with a stop arranged on the light influencing means in such a way that the spring arm is bent out when the fastening element is displaced into the unlocking position.
- the solution according to the invention is characterized in particular by the extremely simple construction of the fastening element. This can be produced, for example, from a single, correspondingly punched and bent piece of sheet metal and thus very inexpensively. Beyond that, no other elements such as Compression springs or the like necessary.
- a particularly advantageous development which is the subject of claim 2, makes it possible, however, that the light influencing means can be placed on the carrier element without any actuation of the fastening element, the latching noses initially withdrawing automatically during the placement and then snapping into the latching recesses of the carrier element.
- This is achieved in that a further inclined ramp is provided on the spring arm, which is perpendicular to Arranged along the longitudinal axis of the spring arm and inclined relative to its bending direction, when the light influencing means is put in place, it cooperates with the carrier element in such a way that the spring arm is bent out before the latching lug engages with the latching recess. This enables a particularly simple assembly of the light influencing means.
- This further inclined ramp can be formed by the top of the locking lug itself, the locking lug preferably being formed by an inclined surface and a support projection arranged below this inclined surface.
- a particularly advantageous embodiment of the fastening element is that it is formed from two spring arms lying opposite one another, each having the latching lug and the inclined ramp or ramps at one end and which are connected to one another at their other end via a connecting web. After assembly, the two locking lugs engage from both sides in the corresponding locking recesses of the carrier element, so that a secure hold of the light influencing means is ensured. At least one actuation tab can be provided on the underside of the connecting web, by means of which the actuation of the fastening element for releasing the latching is simplified.
- the light influencing means preferably have a C-shaped profile in the region of the fastening element, the connecting web of the fastening element resting on the underside of the middle leg. Both side legs of the light influencing means each contain a first elongated hole through which the locking lugs of the spring arms extend. In this way, a secure hold of the fastening element on the light influencing means is achieved at the same time.
- the spring arms preferably also have a C-shaped structure at their end opposite the connecting web, one side leg being formed by the inclined ramp or ramps and the latching lug and the further side leg being formed by an additional contact surface which is located on the underside of the middle leg of the light influencing means rests.
- the contact surface preferably has a contact projection in the form of a bead.
- the locking lugs are each provided with a front and a rear stop edge, which cooperate with the side walls of the first elongated holes.
- the Side legs of the light influencing means each have a second elongated hole, into which slide projections arranged on the ends of the spring arms opposite the locking lugs engage, as a result of which the fastening element is guided securely during actuation.
- the carrier element is preferably an elongated bar to be fastened to a mounting rail of a busbar system.
- a fastening element for fastening light influencing means to a carrier element of a lamp which has at least one deflectable spring arm which contains a latching lug and an inclined ramp which is inclined with respect to the longitudinal axis of the spring arm.
- a particularly advantageous embodiment consists in that a further inclined ramp is arranged on the spring arm, which is arranged perpendicular to the longitudinal axis of the spring arm and is inclined with respect to its direction of bending.
- Figure 1 shows the basic elements of the lamp according to the invention in the assembled state in section.
- Figure 2 shows a detail of a reflector to be attached to the carrier element in a perspective view.
- Figure 3 shows a preferred embodiment of the fastener according to the invention in a perspective view.
- FIG. 4 shows an enlarged illustration of a spring arm of the fastening element shown in FIG. 3;
- Fig. 5 is an enlarged view of the front end of the spring arm
- FIG. 6 shows an enlarged detail from FIG. 1 to illustrate the interaction of the various elements
- 7 shows the arrangement of the spring arms of the fastening element in the locked state
- Fig. 8 shows the arrangement of the spring arms in the unlocked state.
- the exemplary embodiment shown in the drawing relates to a luminaire which is to be attached to the mounting rails of a busbar system in order to implement a light strip.
- the invention is not restricted to such busbar systems, since simple mounting of the light influencing means is also desirable in other lights. For example, it can also be a normal ceiling or hanging lamp.
- Figure 1 shows the basic elements of the lamp according to the invention, which is arranged in the present example on the underside of a C-shaped mounting rail 1.
- the lines for the power supply and possibly also for the transmission of control signals usually run within this mounting rail 1.
- the control and ballast devices for the lamps (not shown here) are arranged within this mounting rail 1 and thus protected from external influences.
- all elements of the lamp are attached to an elongated bar 2, which thus forms the basic structure of the lamp as a carrier element.
- the bar 2 is clamped onto the side of the C-shaped mounting rail which is open at the bottom.
- the beam 2 includes also the sockets for the lamp attached.
- the reflector 3 which is shown in perspective in FIG. 2, has a central region and two laterally projecting reflector wings 3 2 and 3 3 .
- the central area 3 X which is placed on the beam as shown in FIG. 1, has a C-shaped profile, the middle leg being in contact with the underside of the beam 2 in the assembled state, while the two side legs extend perpendicularly upwards ,
- a first slot 4 and a second slot 5 are provided in each of the side legs, the function of which will be explained in more detail later.
- FIG. 1 The representation in FIG. 1, like FIG. 6, corresponds to the section II shown in FIG. 3.
- the attachment of the reflector 3 to the beam 2 is achieved in that the Fastening element 6 has a C-shaped claw 8 on both sides.
- the lower leg of the claw 8 is formed by a contact surface 10 which presses with the aid of a contact projection 11 against the underside of the central region 3 X of the reflector 3.
- the upper side leg of the claw 8 forms a locking lug 12 which engages in the recess 13 formed by the profile of the bar 2. In this way, a clamping effect is achieved, through which a secure hold of the reflector 3 on the beam 2 is ensured.
- the fastening element 6 consists of two elongated spring arms 7 which have the C-shaped claw 8 at their front end and which are connected to one another at their other end via a connecting web 9.
- two actuating tabs 14 are also arranged, through which the fastening element can be displaced in order to release the beam-reflector connection.
- the fastening element 6 can only be produced from a single piece of sheet metal stamped accordingly and bent into the shape shown.
- the side legs of the claws 8 responsible for fastening the reflector 3 are formed, on the one hand, by the abovementioned contact surfaces 10 with the beads 11 arranged therein and by the latching lugs 12.
- a locking lug 12 consists of an inclined surface 15 arranged perpendicular to the longitudinal axis of the spring arm 7 and inclined with respect to the direction of its bending, as well as a support projection 16 arranged underneath of the reflector 3 on the bar 2 is achieved.
- the support projection 16 ensures that the pressure that occurs when the surface 15 is put on actually leads to the spring arms 7 receding and not to a deformation of the inclined surface 15.
- two ramps 17 are arranged, which are slightly bent and which form an angle with the longitudinal axis of the spring arm 7. These ramps 17 are responsible for releasing the lock when removing the reflector 3.
- the interaction of the bar 2 with the C-shaped claws 8 of the fastening element 6 for fastening the reflector 3 is shown in an enlarged view in FIG. 6.
- the locking lug 12 formed by the inclined surface 15 and the support projection 16 engages through the elongated hole 4 of the reflector 3 in the recess 13 of the beam 2.
- the bead 11 of the contact surface 10 presses against the central region 3 t of the reflector 3 from below, as a result of which the desired clamping effect for fastening is achieved.
- the function of the bead 11 is that even in the event that the lower region of the claw 8 is slightly bent out, a defined contact with the reflector 3 is achieved.
- the fastening element is in the latching position, explained in more detail with reference to FIG. 7, in which the latching lug 12 extends through the elongated hole 4.
- the inclined surface 15 comes into contact with the bar 2 and causes the spring arm 7 to be automatically bent out and the latching nose 12 to withdraw.
- the reflector 3 with the fastening element 6 can be placed on the beam 2 without the fastening element 6 having to be actuated for this purpose. If the reflector 3 is placed far enough, the catch 12 then automatically snaps into the undercuts 13 of the beam 2, so that the desired clamping effect is achieved. This makes the mounting of the reflector 3 on the beam 2 particularly simple.
- the locking element 6 In the locking position shown in Figure 7, the locking element 6 is in a position in which both the locking lugs 12 and the inclined ramps 17 through the elongated holes 4 shown in Figure 2 of the side legs reach through the middle region 3 t of the reflector 3.
- the locking lugs 12 and the inclined surfaces 17 then simultaneously engage in the undercuts of the beam 2.
- a further movement of the fastener 6 upwards is prevented by the fact that the front stop edges 19 of the locking lugs 12 come into contact with the side walls of the elongated holes 4 and thus block a further displacement.
- the fastening element is moved in the direction of the arrow into the unlocking position shown in FIG. 8.
- the inclined ramps 17 cooperate with the corresponding side walls of the elongated holes 4 during the displacement in such a way that the spring arms 7 are bent out, so that the locking lugs 12 emerge almost completely from the elongated holes 4.
- the second stop edge 20 comes into contact with the lower side wall of the elongated hole 4 in the unlocking position. Secure guidance of the fastening element is ensured by the sliding projections 18 engaging in the elongated holes 5.
- the fastener according to the invention is characterized by its simple structure, which makes it possible to produce it from a single piece of sheet metal.
