Description

The invention relates to a recessed light according to the preamble of the claim 1.

A recessed luminaire is set up in an installation opening of an installation body to be installed. The recessed lamp can be attached to the recess comprising component can be attached in various ways, e.g. by clamping or by means of special holding parts that interact with the component. The Recessed luminaire for installing a wall, e.g. a vertical building wall or a ceiling or in another built-in unit. With a recessed ceiling light can this either on the ceiling opening or False ceiling can be attached, or the recessed light can be on one above the ceiling beams or false ceiling arranged, e.g. a raw ceiling, e.g. by means of wires or ribbons.

From the publication DE 37 39 076 A1, a recessed light can be seen that the component having the installation opening is attached. In contrast, DE 39 32 881 C2 describes a recessed luminaire that is connected by a wire to one above the associated false ceiling arranged ceiling is attached.

The recessed luminaire which can be removed from DE 37 39 076 A1 is assigned holding means which each have a laterally projecting pivot lever on a bearing part is pivotally mounted, which is on the inside of a side wall of a trough-shaped Base part of the recessed light can be locked in different height positions. For this serve from the bearing part protruding locking elements that Grip latching recesses in the side wall. By locking the Bearing part in different height positions can be a rough presetting Positioning of the bearing part or associated pivot lever can be made. By means of an adjustment screw accessible from below, the swivel lever in the Swivel installation position transversely to the level of the installation opening and thus against Move part of the installation body, which can be a support profile, onto which the false ceiling is supported. At the bottom of the side wall is a side protruding edge part provided that the support profile in the installed state reaches under. By a movement of the The recessed lamp can thus be swiveled against the support profile by Reaching under the support profile by means of the edge part and reaching over the support profile position or clamp using the associated swivel lever. This well-known Design is multi-part, material-intensive and expensive to manufacture. In addition, the assembly and mounting of the recessed light is difficult because of a Pre-position for the bearing part must be predetermined, which must fit, otherwise a Conversion of the bearing part is necessary to position the recessed light in the To reach the range of motion of the swivel lever.

In order to avoid the disadvantages described above, it has already been proposed a holding means for a recessed light fixture connected to the base part To form support leg, the one at its end facing away from the base part Has false abutment legs under the false ceiling, and the one above Holding part is assigned, which in a along the support leg guide on Support leg is held adjustable. One serves to adjust the holding part attacking tie rod that extends beyond the free end of the support leg and thus from is manually accessible from the outside. The holding part can be pulled by pulling the pull rod from above against the false ceiling and in the respective adjustment position lock onto the support leg using a locking device. The Locking device has locking grooves on the outside of the support leg on, into which a latching edge on the holding part can be snapped, whereby on the holding part arranged and the support leg on the inside behind reaching limiting elements an unwanted disengagement of the locking edge in the fastening position of the Holding part is prevented. In the fastening position, the holding part extends obliquely downwards, overlapping the edge of the installation opening. This well-known Design is disadvantageous for several reasons. For one thing, one is needed Relatively large installation opening, since the size of the installation opening is greater than that Holding parts measured dimension of the installation opening or something more must correspond. In addition, not only special locking grooves are required on the support leg, and due to the locking, only an adjustment in stages is specified. A optional adjustment of the holding part, e.g. between these levels, is not possible. Furthermore, the pull rod protrudes above the recessed light, and it protrudes into the free space so that it is not only visible but also disturbs due to its projection, e.g. when cleaning the light exit side of the recessed luminaire.

FR-A-2566848 describes a recessed luminaire of the type specified at the outset, which a lamp housing in the form of an upright tube with a Has mounting flange under the flange. On the outer surface this tubular lamp housing are three distributed around the circumference Dovetail guides are provided, in each of which a flat band parallel to The central axis of the luminaire housing is slidably guided on its the visible side the recessed end remote is connected to a holding part. The flat belts are under an inward elastic bending stress and are so long dimensioned that the holding parts in one with the flat band towards the visible side shifted holding position overlap the ceiling and in one with the Flat band in the ceiling cavity shifted release position due to the Intrinsic elasticity of the flat strip as far as the central axis of the luminaire housing are pivoted so that they are within the projection area of the installation opening are located. In this standby position, the recessed light can therefore be easier Be inserted into the installation opening.

In this known embodiment, the holding parts are in the Ready position in a position in which the recessed light in the recess opening can be used, but there is a risk that e.g. due to material fatigue Flat belts or due to a contact the holding parts with the Edge of the opening when inserting into the opening, the holding parts in a outside shifted position and interfere with the insertion or without an additional Make handling impossible.

The invention has for its object a recessed light according to the preamble of the new claim 1 in such a way that while ensuring a simple Design a simple and easy-to-use installation of the recessed light in the installation opening is possible.

This object is solved by the features of claim 1. Beneficial Further developments of this solution are described in the subclaims.

In the recessed light according to the invention can the holding part in the Shift the area of the second guide section in which it is. With respect to the first Guide section is shifted inwards and therefore no longer over the outer contour of the first guide section or the recessed lamp. That's why she needs Installation opening to be hardly larger than the position of the first Management section requires this, i.e. no bigger than one over two each other opposite guide sections measured dimension. This is a good one Use of space is given, with a given installation opening size Recessed luminaire can be sized accordingly. In addition, the installation the recessed light into the recess opening easily and easy to use because that Not holding part or the holding parts in their inwardly shifted assembly position protrude beyond the first support leg and therefore easier insertion the recessed luminaire is guaranteed in the installation opening.

In the embodiment according to the invention can the size of the installation opening as small as can be kept possible or with a given size of the installation opening the recessed luminaire should be relatively large.

The configuration according to the invention is suitable for Recessed luminaire with a base part, means provided on the base for holding at least one Lamp and for the power supply of the same, Holding means for holding the recessed light in a recessed body, which are connected to the base part and a light distributor, the holding means for the recessed lamp each have a support leg have on which a laterally projecting holding part in a Guide adjustable and lockable in the respective adjustment position is held, and wherein the holding part by a clamp connection with the Support leg is connected by a manually operated Clamping element to open and close or at Effectiveness of a towards the foot area of the support leg directed load moment automatically enters and closes Effectiveness of a directed towards the free end of the support leg Automatically releases the load torque on the holding part.

With such a recessed light is based on the fastening function between the holding part and the support leg on a clamping effect. Therefore can a locking device is eliminated, which leads to a significant simplification contributes because no locking recesses are required. This will make the Manufacturing significantly simplified and also the holding part is easier and adjust more user-friendly, since no unintentional snapping into place when adjusting Locking recesses takes place. In addition, the invention Design the setting positions of the holding part is not stepped Setting positions limited but the holding part can be steplessly on the support leg be adjusted and fixed. This makes the attachment easier, more precise and safer.

The subclaims contain features that are simpler, smaller and safe construction, simplify the installation and adjustment of the recessed luminaire, easy-to-use access to the holding means and their Ensure easy-to-use displacement and also an inexpensive Enable manufacturing.

The vertical distance f between the transverse edge 75 and the rear gripping noses 77 is short and is the present Embodiment about 3 to 12 mm, preferably about 5 to 8 mm. Preferably the first leg section 71 is convex inwardly as a whole, the Rear gripping lugs 77 are arranged in the central region of the bend 71a. Hereby the rear gripping lugs 77 are in the displacement position with a convex curve on the inside of the support leg 24b or 53, whereby the displacement of the Clamping part 26 in its indicated shift position on Support leg 24b and 53 is facilitated. The latter is also promoted by the fact that the transverse edge 75 on a slightly upward, preferably rounded, bent Tongue 79 is arranged so that the transverse edge 75 is not in the shift position but rather a preferably rounded contact surface of the tongue 79 on the support leg 24b or 53 is present. It is also advantageous to have the free end of the clamping part 26 to form an upward rounded or angularly bent end leg 81, what contributes to stabilization.

If the pressure leg 26a of the clamping part 26 around the rear gripping lugs 77 or Transverse edge 76 is pressed inwards or upwards (arrow 80), the latter are due the load moment acting on them pressed against the support leg 24, 53, whereby the clamping connection KV jams automatically. By pivoting in the the arrow 80 in the opposite direction reaches the clamping part 26 in its release and Shift position.

It is also advantageous to have a U-shaped one in the pressure leg 26a Provide cutout 82 formed pressure tongue 83, the foot area in the vicinity the transverse edge 75 and which is towards the free end of the Pressure leg 26a extends and at a short distance of about 5 to 12 mm of which ends. The pressure tongue 83 has the advantage that in the clamped state of the Clamping part 26 the latter not only with its free end but also with the free end End of the pressure tongue 83 presses on the false ceiling 7a, causing the pressure leg 26a presses against the false ceiling 7a at several points. Preferably the free one End edge 84 of the pressure tongue 83 is formed concave, which at the free corners of the Pressure tongue 83 projecting canines 85 are created, which are selective and thus press effectively on the false ceiling 7a.

The configuration of the clamping part 26 according to FIG. 9, in the same or comparable Parts with the same reference numbers differ from the Design described above in that a pressure tongue 83 is not available and the tongue 79 is formed considerably longer and narrower, on both sides of the tongue designated here with 79a, cutouts 73a are provided for free use End of the pressure leg 26a are extended portions of the cutout 73. How the pressure leg 26a is thus already in the exemplary embodiment described above connected by two lateral webs 26c to the clamping leg 26b, which the Limit cutouts 73a laterally.

In the area of its free end, it can be approximately parallel to the pressure leg 26a extending tongue 79a widened in the sense of a flat head 79b, preferably with a straight or convexly rounded transverse edge 75 which in the Clamping position rests on the support leg 24b or 53. The curved up Curvature of the tongue 79a is in the present embodiment in the region of the Head 79b arranged.

In order to improve the elasticity of the pressure leg 26a, one can be used for free End of the pressure leg 26a directed distance from the foot region of the tongue 79a, preferably a transversely extending slot 26d may be provided. It is also advantageous, the connecting leg 26c of the pressure leg 26a to the free end to be convergent, as shown in FIG. 9.

To improve the clamping effect, the following measures can also be taken Clamping parts 26 according to FIGS. 7 to 11 can be provided. For one, it is beneficial to The transverse edge 76 in the upper region of the clamping leg 26b is not straight but convex or curved form so that they on the support leg 24b; 53 in their middle The area lies point-like. This ensures the clamping functional reliability improved. 6, the curved transverse edge 76 is indicated by dash-dotted lines. In Fig. 9 it is shown with a solid line.

It can also be advantageous to improve the clamping effect Angle the pressure leg 26a slightly downward on a transverse line 26e, as is the case Fig. 7 shows. The transverse line 26e is in a to the free end of the Pressure leg 26a directed distance p from the front edge or transverse edge 75, the tongue 79 or 79a. 7, the transverse line is located 26a in the foot area of the tongue 79, in contrast in the embodiment according to FIG. 9 behind the widened head 79b. It should be emphasized that the tongue 79 and 79a itself is not angled or bent, because when you bend the Pressure leg 26a in the region of its connecting leg 26c Angular movement follows. The angular size w2 of the bend is approximately 10 °. Due to the bend, the pressure leg 26a presses in in its working position a slightly more inclined position against the ceiling or false ceiling 7, 7a or a corresponding part of an installation body. 9 can the tongue 79a is designed to be slightly convergent towards its free end, as is the case is shown.

The configuration of the clamping part 26 differs from this configuration 10 and 11 in that the transverse edge 75 at the free end in Tongue 86 extending toward the guide passage 74 is arranged by two starting from the cutout 73, towards the free end of the pressure leg 26a extending slots 87 is formed, which extend so far that they with overlap the leg portions of the U-shaped cutout 82, thereby in between a connecting web 88 on the one hand for the pressure tongue 83 and another is formed for the tongue 86. Which is preferably in one level Extending tongues 83, 86 are by cranking down the Connecting webs 88 slightly, e.g. by about 2 to 8 mm, preferably by about 4 mm offset downwards, so that the transverse edge 75 slightly is offset below. In addition, the arrangement is such that the transverse edge 75 with a low spring tension among other things in the area of the stripped Connecting webs 88 in the direction of arrow 89 against the support leg 24b or 53 presses. As a result, the clamping effect of the clamping part 26 on the support leg improved. By pivoting the clamping part 26 and the tongue 86 downward the tongue 86 becomes slightly in the indicated shift position bent upwards. In this functional position, the clamping part 26 can be Maintaining a low pressure system of the tongue 86 on the support leg 24b or move 53 vertically.

The plug-in recess 116 extends only part of the length of the base leg 109, being in one Distance h from the base web 114 begins to go down through the longitudinal bead 115 extends and at a small distance i from the free, approximately parallel to the base web 114 extending edge of the base leg 109 ends. In the upper area the Plug-in recess 116 on one or both sides of a plug extension 117, the Function is described below.

Bent end walls 118 are provided on the front ends of the base part 2 partially limit the cavity of the base part 2 at the end.

The base part 2 is in one piece as a stamped / bent part from a top view in FIG. 26 shown circuit board made of sheet steel.

The support part 101 consists of a U-shaped first connecting part 101a Connecting the support legs 24 and a second connecting part 101b for connecting of the base part 2. The support part list with a web part 119 and its longitudinal edges bent legs 121 shaped U-shaped in cross-section, it being for a is arranged transversely to the base part 2 extending arrangement. In the end areas of the Leg 121 is the locking device 102 for releasably connecting the associated support leg 24 arranged. The part of the support part 101 belonging to Locking device 102 is through a plug-in recess 122 in one leg 121 and formed by a latching tongue 123 in the other leg 121. The Locking tongue 123 is through a cut 124 from the associated leg 121 cut out and bent obliquely inwards (see Fig. 28), making them extends obliquely down to the vicinity of the web part 119. The free end of the Latch tabs 123 may be tapered onto a latch pin 125 as is Fig. 27 shows. The two latching devices 102 are arranged reversed, so that in each leg 121 a plug-in recess 122 and a latching tongue 123 are arranged.

The second connecting part 101b is formed by two connecting legs 126, 127 formed, which extends from the web part 119 to the side facing away from the legs 121, here downward, and are preferably bent in one piece, the distance between the connecting legs 126, 127 is dimensioned so large that the base part 2 can be used in between. In the present embodiment, both are in the foot area Connecting leg 126, 127 a rectangular step bend 128 is provided, the arrangement is such that the base part 2 with little movement fits between the innermost step sections 129.

As can be seen from FIG. 20, each support part 101 is also one Stamped / bent part that is stamped and bent in one piece from a sheet metal sheet.

In the area of the horizontal support leg 24a is on one side projecting plug pin 137 and on the other side a plug recess 138 arranged, which are parts of the locking device 102. The plug pin 137 is with some play in the plug-in recess 122, the horizontal Support leg 24a rests on the web part 119. In this position the Plug-in recess 138 of the latching tongue 123 or the latching pin 125 see above assigned that the latter snaps into the recess 138. This is the Support leg 24a easy to handle, stable and securely detachable on the support member 101 attachable. The plug pin 137 and the plug recess 138 are preferably in the Area of a reduced with respect to the vertical shaft of the support leg 24 Width k tapers, with which it can move between legs 121 with little movement of the support member 101 fits. As a result, two are possibly offset in the longitudinal direction arranged step surfaces 139 created, which abut the end face of the support member 101 can and thereby both facilitate handling when plugging together as also improve stability. At the foot of the support leg 24 is the Abutment leg 25b bent horizontally, preferably in the area of one Constriction in the form of two opposing grooves 141 that it enable the side edge portions 142 extending up to these grooves 141 slightly angled, resulting in an approximately spherical support surface for the body 7 is formed.

The sliding guide 27 has a longitudinal slot 135 in the support leg 24 which extends from the Foot region of the vertical support leg 24b into the arch or the bend 29 extends and in the presence of a vertical support leg 24e between the Bow 29 and support leg 24a can extend into the support leg 24e. The vertical support leg 24e is present when the arch 29 supports 101 should protrude. At the end of the longitudinal slot 135 facing the support leg foot preferably a narrow slot 142 connects in the middle, which fits into a Slot extension 143 opens. The latter is on the curved part and in the assembled State in the section of the support leg 24 protruding from the supporting part 101 or in horizontal section or step bend 134 arranged.

In the design of the clamping part 26 and its clamping connection KV according to the 13 and 24 to 36 is the clamping member 26 by a lower and upper Clamping legs 26a, 26b are formed which have an open angle w3 of enclose about 45 °, the apex preferably being rounded. In the field of Curvature or the end region thereof are located in the clamping legs 26a, 26b two sides of two guide grooves 144, 145 one above the other, of which the top through lateral recesses are formed and the lower by initially to the outside pointing tongues 146 forming angular cutouts 147. The tongues 146 are preferably rounded downwards, creating a sharp recess edge is avoided and instead a rounded contact surface 148 is created. By doing A narrow slot extends in the free end region of the upper clamping leg 26b 149, which opens into a preferably rounded slot extension 151. In the area an elongated cutout 152 of the lower clamping leg 26a is arranged from the inward end of a narrow slot 153 goes out into a preferably rounded slot extension 154 opens. The arrangement is so that the slot extensions 151, 154 are approximately vertically one above the other. For Stabilizing the clamping leg 26a, it is advantageous to use lateral to provide bent reinforcement legs 155. In the free end area is the Clamping legs 26a bent downward in an approximately Z-shaped manner, with its support section 156 tapered and can have laterally slightly upwardly curved edge strips 156a. The free end of the upper clamping leg 26b is preferably rounded or wedge-shaped. According to FIG. 31, the clamping part 26 is preferably in one piece manufactured stamped / bent part e.g. made of steel or spring steel.

The sliding guide 27 is in the present embodiment by the Longitudinal slot 135 and the edge strips 156 of the support leg 24b delimiting it educated. For this purpose, the distance m between the guide grooves 144, 145 is one small movement clearance dimensioned smaller than the width n of the longitudinal slot 135, see above that the transverse edges of the guide grooves 144, 145 with the edge strips 156 Reach behind the play of movement. 13 and 24 show the clamping part 26 in its Clamping position in which it rests on the installation body 7 and with the support leg 24b is jammed. The jamming takes place through the contact of the outer transverse edges 157 of the upper guide grooves 145 on the outer sides of the edge strips 156 and Contact surfaces 148 on the inner sides of the edge strips 156. Because of the relative large length ratio of the effective distance o between the transverse edges 157 and associated contact surfaces 148 and the length p of the clamping leg 26a results automatically a jam in the sliding guide 27 when the clamping part 26 after is shifted upwards, even if the clamping leg 26a bends upwards entry. The clamping effect is still an edge effect of the transverse edges 157 reinforced. In contrast, the clamping part 26 can be moved relatively easily if the point of engagement for its displacement is in the vicinity of the guide grooves 144, 145 see distance q. When the clamping part 26 moves against the installation body 7 is, the clamping connection KV in the sliding guide 27 results automatically due to the clamping or bending stress occurring on the clamping leg 26a is illustrated by the upward arrow 158.

The displacement can be done manually or by means of a displacement device. in the In the first case, this can be handled easily in the area between the Base part 2 and the installation body 7 take place. In the second case they are Slot extensions 151, 154 are preferably provided, to which reference should also be made is taken.

The quick connect connection or locking device 105 is by a Latching lug 161 and a latching edge gripped by the latter, which interlock elastically and are therefore detachable. In the present The latching lug 161 is part of a latching spring 162, the one Latching projection 163 engages behind elastically. The locking spring 162 is attached to the holding device 103, preferably by an extension of the Connection leg 127 formed and in particular as a separate component thereon attached, e.g. by means of a screw or rivet which extends through the holes 132 and 132a screwed or riveted. The latching lug 161 is in one piece with the latching spring 162 formed by bending, the locking lug 161 on the underside Has bevel 164, which an automatic bending and snapping the Locking lug 161 behind the locking projection 163 when closing the Locking device 105 guaranteed. The latch spring 162 is preferred made from flat spring steel. About turning in the screw or rivet connection To prevent the locking spring 162 has a small at its foot end Bend 165 on, in a recess of the component supporting it, here in a Recesses recess 165a on the connecting leg 127. Preferably the shaft 160 of the locking spring 162 in its foot area in the form of an upside down U shaped, which increases the length and improves their elasticity becomes. The free end region of the locking spring 162 is in the locked position from the side of the existing reflector 4, so that it is easy to use tangible attack element 166 for bending and opening the Locking device 105 can serve. It is a medium or two in the End areas of the downlight 1 arranged quick-closing or Locking devices 105 are provided.

A quick release or latching device of the construction described above and Function can also be provided for the latching device 58. In the In the present embodiment, the latching device 58 is also due to the Locking spring 107 formed with the locking lug 108 integrally molded thereon, which can be attached to the holding device 103 or preferably to the reflector 4. The latch spring 107 is preferably S-shaped, with its upper belly forms the locking lug 108.

Another difference from the embodiment of FIG. 13 is that between a distance is provided between the ends of the supporting part 101 and the curves 29, which increases the sliding guide path and reduces the height of the support legs can be.

It is also advantageous in the present embodiment, the holding device 103 so that the distance between the support legs 24 is adjustable and thus the recessed light 1 can be fitted to installation openings 8 of different widths. For this purpose, different support legs 24 with horizontal lengths of different lengths can be used Support legs 24a or support parts 101 of different lengths can be provided, the Differences in length of existing increments in the width of the installation opening 8 are adjusted. Within the scope of the invention it is also possible to use several Locking device parts of the locking device 102 on the support part 101 or on to provide the horizontal support legs 24a, the distance between several existing locking device parts on the increment of differently wide installation openings 8 is adapted.

30, which shows only one side half of the recessed light 1, the clamping part 26 is a mechanical adjusting device 181, in particular for its Assigned displacement in the clamping position. The adjustment device 181 is through a pulling device is formed with a pulling rope 182, which on the clamping element in the Near the sliding guide 27 attacks and from the free interior 183 in front of the Installation body 7 is accessible here, e.g. in that the pull rope 182 e.g. at dismantled light distributor 3 or reflector 4 hangs down into the interior 183. For such a cable drive, the slot extensions 143, 151, 154 in the Support legs 24 and the clamping parts 26 are provided. 30 clearly shows the pull rope 182 extends on the outside of the associated support leg 24, here of its vertical support leg 24b. The pull rope 182 preferably does not engage lower clamping leg 26a but on the upper clamping leg 26b, it being the interspersed lower clamping leg in a through hole with movement, preferably with a protective sleeve 184 attached to the pull rope 182, which the The pull rope protects against damage to the edge of the hole.
