Description

VARIABLE ADJUSTABLE QUICK FASTENING SYSTEM FOR LUMINAIRES

ON MASTFLAP DESCRIPTION

The present invention relates to luminaires for mounting on a mast, such as masts. Street lights, which have a luminaire housing and a mast flange. The mast flange has a receptacle which makes it possible to attach the luminaire to the end of a lamp post.

For such lamps, it is common in the prior art to provide tengehäuse an adjustment device between the mast flange and the luminaire, which makes it possible to bring the light against ^¬ over the festzumontierenden mast mast flange in different angular positions. An example of such a pole attachment for street lights is described in DE 10 2010 033 977 AI. In this prior art, a lamp is attached to at least two bearing shells on a roller ^¬ shaped bearing element, wherein a releasable Klemmvor ^¬ direction is provided to set the bearing shells in different angular positions with respect to the cylindrical Lagerele ^¬ ment. Although this solution enables a variety of angular positions, the design is relatively expensive.

A simpler variant for the variable attachment of a mast ^¬ flange to a lamp housing provides that the mast flange has a circular segment section with notches, which rests against a congruent circular segment section on the Leuchtenge ^¬ housing. The measures see ^¬ nen over the entire contact surfaces notches allow the lamp housing animals to assembled with respect to the mast flange in different ^¬ current angular positions. However, to attach the lamp housing to the mast flange fastening means, for example in the form of several screws, necessary, which connect the circular segment portion of the mast ^¬ flange with the lamp housing. This Fixed To ^¬ supply medium must essentially take the entire gravity and ggf- wind force acting on the housing, on ^¬. The forces can be significant because such

Lights often have a large overhang over the mast flange, so that a significant torque of the Ge ^¬ weight of the light on the connection between the mast flange and the lamp housing acts. Correspondingly many screws or other releasable fastening means must be seen ^¬ before.

Object of the present invention is to provide a lamp with an adjustable mounting system for the mast flange, which is easy and quick to install and also requires as few separate components.

The problem is solved by a luminaire according to claim 1.

A special feature of the luminaire according to the invention is that the mast flange has at least one plug-in element, which optionally in different insertion positions of the

Luminaire housing can be inserted, and further the mast flange has a spaced from the plug-in area support portion on which the lamp housing with a Anlageflä ^¬ che is supported on the mast flange. By the combination of the plug element and the supporting area connecting a Zvi ^¬ rule the lamp housing and the tower flange can be achieved, which alone already ensured due to the geometry of the components holding the light housing to the tower flange. Due to the interaction of the two contact areas, namely the plug-in element and the support area, the torque, which is exerted on the connection between the mast flange and the lamp housing by the weight of the lamp housing is collected. Further, it is possible, characterized in that a plurality of insertion positions are provided for the plug-in element, to fix the lamp housing to the mast flange in different angular positions. Although the angular positions are only gradually adjustable according to the number of insertion positions on the lamp housing. However, this is generally sufficient for the desired alignment of the light exit surface of the light ^¬ tengehäuses compared to the mast. Un ^¬ terschied to the above cited prior art no screw elements are necessary to fix the mast flange of the luminaire housing. This allows a faster installation of the lamp and also it reduces the number of necessary components.

It has always been assumed in the prior art that the luminaire housing must rotate about an actual axis of rotation or a virtual axis of rotation with respect to the mast flange. In the present invention, this concept has been deviated to the extent that the insertion positions and the associated contact points between the support areas of the contact surface need not lie on a common circular path. In other words, the predetermined by the insertion positions of the lamp housing relative to the mast flange differ not only by a rotation, but may also also differ by different heights between the mast flange and the lamp housing. The usual in the prior art concept, the light only to rotate about a predetermined axis is thereby abandoned.

According to a preferred embodiment, the insertion positions are arranged in the luminaire housing so that the light Exit surface of the lamp housing relative to the mast flange over an angular range of at least 3 °, preferably of at least 10 °, 15 ° or 20 °, is gradually adjustable. For example, at least two, three or four plug-in positions can be provided, wherein between each two adjacent plug-in positions, the lamp housing is displaced relative to the mast flange by an angle of at least 3 ° or 5 °. According to a preferred embodiment, the mast flange has two plug-in elements which can be inserted selectively into one of the plug-in positions on the lamp housing, and the contact surface of the lamp housing is supported on one of two support areas of the mast flange spaced apart from the respectively plugged-in plug element. According to this embodiment, the mast flange can be in two completely different positions, for example, pivoted by 90 ° and rotated 180 °, attach to the lamp housing by selecting one of the two plug-in elements on the mast flange. For each of these two alignments, the mast bottle can also be fine-tuned by selecting one of the plug-in positions on the lamp housing. In other words, in each of the two basic positions, the luminaire housing can be adjusted above the mast flange, for example in an angular range of at least 3 ° to at least 20 °. This construction is particularly suitable for lights that are to be attached to different masts. In principle, there are two different Montagela ^¬ gen a pole lamp on a lamppost. The luminaire pole can extend vertically up to the luminaire and the luminaire housing is placed at an angle of approximately 90 ° on the vertical luminaire pole end. This mounting position is referred to as "attachment mounting." The mast holder must be approximately 90 ° to the longitudinal axis of the luminaire or the Light exit surfaces of the lamp housing extend. Alternatively, the mast flange can be fastened to the luminaire housing in such a way that the mast projection runs approximately parallel to the longitudinal extension of the luminaire housing or the light exit surface of the luminaire housing. This mounting position is also referred to as "shoulder mounting" and is suitable for attaching lights to a horizontally extending mast end. Therefore, according to a preferred embodiment, the two plug elements are provided at an angular distance from the mast flange such that the mast flange is optional in two pivoted by 90 ° positions on the lamp housing mon ^¬ tierbar is, if either one of the two plug elements in the same insertion position of the lamp housing ^¬ inserted, wherein the longitudinal axis of the mast support relative to the light exit surface in a cross section through the longitudinal axes ^¬ Luminaire housing and the mast reception in a Win ^¬ angle of about 0 ° and about 90 ° occupies a value of 1.5 ° or 91.5 ° is used in practice to prevent that in a not exactly aligned luminaire mast Negative angle of attack of the light ^exit surface is created For the two plug-in elements in this embodiment, therefore, the same luminaire can be set up both for the attachment mounting and for the attachment mounting. In two basic configurations may be made by selecting the Einsteckposi- functions for the respective plug-in element further still Feinab ^¬ humor, that the lamp housing can be adjusted relative to the tower flange in an angular range of at least 3 ° to at least 20 ° by selecting the insertion position.

According to a development of the last-mentioned embodiments, it is further provided that the two plug-in elements on the mast flange are each provided with a plug-in area and the associated plug-in area. gene spaced support region of the mast flange are formed. In other words, the mast flange has two areas, which can optionally ^¬ nen as a plug-in element and as a support area. The plug-in positions or the contact area on the luminaire housing are in contrast set up in such a way that they can interact positively with both elements on the mast flange. In this way it is particularly easy to construct a mast flange, which in two different layers, namely for the top assembly and the neck mounting, on

Luminaire housing can be mounted and in each of these Grundstel ^¬ lungs by selecting the insertion still at an angle to the mast flange can be fine-adjusted.

According to a preferred embodiment, the abutment region has a mandrel which interacts with an opening or a surface in the support region of the mast flange so that the luminaire housing can be removed from the mast flange only in one direction opposite to the insertion movement of the plug element into one of the arbitrary insertion positions. The mandrel on the contact area of the luminaire housing can extend through a small opening in the support area of the mast flange. Alternatively, it can also be provided that the mandrel rests against a surface of the mast flange, in particular an inner surface of the mast flange ^¬ . In the embodiment with two Steckele- elements or track areas on the tower flange can also be provided, that the mandrel rests in a mounting position, for example, the top mounting on a surface of the support portion, currency ^¬ rend in the other mounting position, for example the lug assembly, the mandrel extends through an opening in the support area of the mast flange. The thorn has the function that that

Luminaire housing can be removed only in the direction in which the luminaire housing is plugged onto the plug-in ^¬ . As a result, in particular tilting moments can be intercepted be acting on the connection between the mast flange and the lamp housing by the gravity of the lamp housing. In this embodiment, even with conventional wind loads acting on the lamp housing in the mounted state, the forces already intercepted, which could possibly solve the lamp housing from the mast flange. Only exactly in the plug-in direction, which runs approximately in the horizontal, the lamp housing can be lifted from the mast ^¬ flange. In this direction, as a rule, only small momentum forces occur. Alone by the weight ^¬ force of the lamp housing, which counteracts this direction of force ^¬ , therefore, the secure mounting of the lamp housing is ensured on the mast flange. According to a preferred embodiment, the lamp further comprises a spring, which applies an elastic force for fixing the mast flange to the lamp housing in a region between the contact surface and the support region, which counteracts ei ^¬ nem disengagement of the support region of the contact surface. The spring element serves as an additional safeguard, so that the luminaire housing can no longer be lifted off the mast flange, not even exactly opposite the insertion movement. For this purpose, no particularly large forces of the spring element are applied, because in contrast to the usual constructions in the prior art, the weight of the lamp housing alone by the plug and the support area on the mast flange are already included. The spring only serves as an additional safeguard, which itself does not have to absorb any significant forces.

According to a development of the last-mentioned embodiment, the spring is supported by one or two free ends on the lamp housing in order to apply the elastic force. For example, it may be provided that the spring element et ^¬ wa U-shaped, wherein the free legs are formed by the two free ends of the U. The middle region of the U-shaped spring element is clamped in the region between the support element and the contact surface and presses with one or more projections on these regions when the free legs are rotated in the direction of the lamp housing and are each hooked into recesses in the lamp housing , As a result, the spring acting as a securing element can be assembled without tools, as well as the other components of the luminaire, by the way. By the leverage, which the free

Thighs in relation to acting as pressing element Ab ^¬ sections of the spring apply, the necessary contact pressure is already achieved by the fact that the free legs are purely borrowed by hand biased and locked in the corresponding recesses on the lamp housing.

According to a preferred embodiment, the lamp housing to a Kipphebelverschluss which is adapted to fix the supporting portion of the Mastflansches relative to the contact ^¬ surface of the lamp housing. The rocker arm can be designed in the manner of a closure of a ski boot, which engages with the bracket on a projection of the lamp housing ^¬ and after overcoming a dead center in a pivoting movement of the rocker arm clamps the bracket so far that the

Protected projection on the lamp housing relative to the rocker arm on the mast ^¬ flange. This embodiment can be used in particular as an alternative to the above-mentioned locking spring, wherein both systems can complement one another in an embodiment. By fixing the support area of the mast flange to the contact surface, here too only a fuse is meant, because the acting weight or wind forces are already affected by the plug-in or support function of the plug element and the support area are received.

According to a further development of the last-mentioned embodiment, the rocker arm lock engages with a bracket into one or two projections extending from the lamp housing through one or two recesses in the support area, in particular one or elongated slots in the support area, in each possible assembly position is predetermined by the optional insertion of the plug element in one of the insertion positions extend. The Kipphebelverschluss must, as vorherge ^¬ term, while serving merely as a security element This embodiment is particularly suitable for variants of the lamp, which use a conventional mast flange in connec tion with a new luminaire housing. For example, the mast flange can be formed with a half-shell-shaped receptacle as described in the prior art. In this case, the front and the rear edge of the semicircular shell acts as a plug element or support element of the mast flange. The luminaire housing is matched with the insertion positions or the abutment area exactly to this shape of the plug element or support area. In such mast flanges slits or recesses were provided in the prior art, which were intended to fasten with screws the Leuchtenge ^¬ housing on the mast flange. Instead of this

Screwdrivers, the new luminaire housing now has projections which have about the diameter of the screw, but of course without a screw head, and are fixedly provided on the housing Leuchtenge. At the region of the one or more projections, which extend through the recess of the mast flange, the bracket of the rocker arm lock can angrei ^¬ fen. This embodiment is preferred when it comes to redeveloping old pole lights. Often it is due to Kor It is no longer possible to remove the old mast flange from the mast. In this embodiment, however, the old mast flange can continue to be used and only the old Leuchtenge ^¬ housing is replaced by a new lamp housing, which has the features previously described. As a result, a refurbishment of the lamp is possible, even if the old mast flange must continue to be used.

Other features and advantages of the present invention will become apparent from the following description of preferred embodiments, taken in conjunction with the accompanying drawings. The figures show the following:

FIG. 4 shows a perspective view of the luminaire according to FIG. 1 with a spring element.

Figure 5 shows a perspective view corresponding to Figure 4, wherein the spring element is secured.

FIG. 6 shows a perspective view of an alternative embodiment of a luminaire, which has a rocker arm has to lock the mast flange on the lamp housing.

Figure 7 shows an illustration corresponding to Figure 6, wherein the mast flange is connected to the housing.

Referring to Figures 1 to 5 show a first exporting ^¬ approximate shape of a luminaire for attachment to a mast will be described. The luminaire has a mast flange 10 and a luminaire housing 20, wherein in all of the illustrations only the rear part of the luminaire housing 20 is shown. It is to be understood that the luminaire housing extends further and has a light exit surface on at least one side, in the figures on the downwardly facing side.

The mast flange 10 has a mast receptacle 12 in the form of a cylindrical opening, which is adapted to be plugged onto the end of a lamppost (not shown in the figures). In a side wall of the mast flange 12 2 screw holes 14 are provided through which screws can be passed to clamp the mast flange to a lamppost.

The mast flange 10 has on the mast receiving 12 opposite side a plug-in element 16 and spaced from the Ste ^¬ ckelement support area 18. Both areas 16 and 18 are formed in the illustrated embodiment by edges on a mast approach 12 opposite end of the mast flange 10 ,

The luminaire housing 20 has a plurality of insertion positions 22 in the rear region, four in the embodiment shown, and a contact surface 24. The insertion positions 22 are formed in the form of depressions whose shape is matched to the shape of the plug-in element 16. The plug-in element 16 can be plugged into any of the plurality of insertion positions 22. In each of these positions of the support portion 18 comes to lie in the region of the contact surface 24, at which is verste ^¬ hen that 12 of the supporting portion 18 abuts when the use of the different plug-in positions on the bearing surface 24 in slightly altered positions. Referring to Fi gur ^¬ 2 is shown how the mast flange 10 with the Ste- ckelement 16 is inserted into the lowermost of the four insertion positions 22nd The support region 18 rests against the contact surface 24. By the shape of the insertion positions 22 with respect to the male member 16 and the shape of the abutment surface 24 with respect to the support portion 18, the lamp housing 10 rests on the mast flange 20 alone by its own

Gravity. The plug-in positions 22 are so ausgebil ^¬ det, that the plug-in element 16 can be inserted only in a defined direction, so that the lamp housing 20 can not solve by a tilting movement. The illustrated embodiment also has on the contact surface 24 on a mandrel 26 which protrudes from the contact surface 24. As shown in Figure 2, the mandrel engages the mast flange 10 and abuts there on an inner side adjacent to the support portion 18. The mandrel 26 prevents the lamp housing from being released from tilting by gravity from the mast flange. Through the mandrel 26, it is only possible to lift the lamp housing 10 only counter to the direction which is predetermined by the insertion direction of the plug element 16 in any of the insertion positions 22.

In each of the four possible insertion positions 22, the lamp housing 20 relative to the mast flange 10 has a slightly changed angle. For example, the Change the angle of the luminaire housing relative to the mast flange in each of the insertion positions by at least 3 ° or 5 °. As a result, by the selection of the insertion positions an adjustment of the lamp housing relative to the mast flange, which is fixed to the lamp mast, possible.

Referring to Figure 3, the same light is Darge ^¬ represents, the mast flange 10 is fixed relative to the lamp housing 20, however, in a rotated by 90 ° and rotated 180 ° position. In the illustrated embodiment, the support portion 18 and the male member 16 of the mast ^¬ flange 10 exchange their function. The support portion 18 acts in the ^¬ this mounting position as a plug-in element and the plug-in element 16 acts as a support element in this assembly. As in the Figure 3 illustrates ones shown,, the plugged portion 18 in one (the top) insertion position 22, while the element 16 is supported on the installation surface ^¬ 24th As previously ^¬ be written in reference to Figure 2, is already provided by inserting and supporting the elements 16 and 18, a secure hold of the Mastflansches 10 to the lamp housing twentieth In this mounting position, the mandrel 26 extends through an opening 18 in the mast flange 12 near acting in this mounting position as a plug-in member 16. The mandrel 26 has the same function in this mounting position, as previously described. It prevents the luminaire housing from being able to be released from the insertion position by a tilting movement, in that the mandrel 26 in conjunction with the opening 18 only allows the luminaire housing to be lifted off the mast flange exactly opposite the direction of the insertion movement.

The mounting position of the mast flange 10 on the luminaire housing 20 according to FIG. 2 is referred to as top mounting, because this configuration is set up in order to mount the luminaire on a NEN to install a vertical end of a lamppost. The mounting position according to Figure 3 is referred to contrast, as approach mounting, because it is suitable for mounting the lamp to a horizontal mast end. As previously described, the plug-in element 16 or 18 can be plugged into any of the plurality of plug-in positions 22 both in the lug assembly and in the attachment assembly. This makes it possible to adjust the mast flange relative to the luminaire housing both for lug mounting and for attachment mounting at an angle, because the insertion positions 22 each define a different angular position of the lamp housing relative to the longitudinal axis of the mast holder. In one embodiment, for example, an angle offset of 5 ° can be set between each two adjacent plug-in positions, so that the luminaire can be adjusted by steps of 5 ° through the illustrated four plug-in positions by selecting the plug-in position. This adjustment is possible both in the attachment assembly according to FIG. 2 and in the attachment assembly according to FIG. In the first insertion position, as shown in Figures 2 and 3, the light exit surface ei ^¬ nes lamp housing takes an angle of about 90 ° in the attachment ^¬ assembly and an angle of about 0 ° in the neck mounting a. Preferably, the angle is slightly larger than 0 ° or 90 ° is selected, namely, for example, 1.5 ° and 91.5 °, in order to prevent that the light exit surface ei ^¬ nen at a not exactly vertically or horizontally extending by construction tolerances pole light negative Angle to the earth's surface occupies. Such an orientation would be immediately recognizable as faulty when the light is on, while a slightly too large angle of attack for the appearance of the light for the viewer is not perceptible. Referring to Figures 4 and 5, a further Siche ^¬ approximately mechanism will be described. Figures 4 and 5 show the luminaire housing 20 with the mast flange 10, which is mounted for attachment mounting. In addition to the previously described elements, a spring 30 is also provided, which is inserted in a region between the support element 16 and the abutment region 24. The spring 30 has approximately the shape of a U, wherein the central region of the U between the Stützele ^¬ ment 16 and the contact area 18 is inserted so that it is rotatable. In the central region two further pressing elements 32 formed by the curvature of the spring element 30 are provided, which are still removed from the support region in the position of the spring 30 shown in FIG. By turning the spring 30, the pressing elements 32 move in the direction of the support area and exert an elastic force on the Stützbe ^¬ rich in the direction of the contact area 24 from. As a result, removal of the lamp housing 20 from the mast flange 10 is also prevented in the direction opposite to the insertion movement of the plug element. The connection between the mast flange 10 and the lamp housing 20 is thus secured in all directions. The spring element 30 has two free legs 34, which are formed by the lateral ends of the U. These ends can be hooked into recesses on inner walls of the lamp housing, as shown in Figure 5. As a result, the spring 30 is fixed in position on the lamp housing, wherein the elastic ^¬ cal force exerted by the pressing elements 32 on the support area, by the opposing force with which the free ends 34 are attached to the lamp housing, is applied. Due to the length ratio of the pressing elements 32 to the free ends 34, a lever ratio is also brought forth, which he ^¬ allows to deflect the free ends 34 only by hand to produce a corresponding high contact pressure by the pressing elements 32. Referring to Figures 6 and 7, an alternative From ^¬ EMBODIMENTS shown, wherein the corresponding in the previously described embodiment be ^¬ elements are provided with the same reference numerals. The mast flange 10 has on the mast receiving side opposite a circular receiving element, the upper and lower edges of the plug element or the support portion 16 and 18 correspond. The mast flange 10 in the embodiment shown has ribs on the inner side facing the luminaire housing, which however are irrelevant to the embodiment shown for attaching the luminaire housing. In fact, it is a mast flange of an older type, which is now used modified in conjunction with a novel lamp housing 10.

The plug element 16 and the support portion 18 cooperate with several insertion positions ^¬ ren 22 and with the contact area 24 on the lamp housing 20 in the same manner as embodiment described in the preceding.

Instead of the spring element 30 for securing the connection, however, a rocker arm lock 40 is provided in this embodiment. This is pivotally mounted on the lamp housing 20 and has a lever 42 and an attached thereto ^¬ th bracket 44.

The lamp housing 20 has in the region of the contact surface two projections 26 which extend through longitudinal slots 19 ^λ in the mast flange. At incisions of the projections 26 ^λ , the ends of the bracket 44 engage and be tightened by tilting the lever 42 about a dead center. As a result, a fuse, similar to the one previously described for spring 30, is provided. written, given between the mast flange 10 and the lamp housing 20.

Numerous modifications of the above-described embodiments may be made without departing from the present invention, which is defined by the claims. In particular, more or fewer insertion positions may be provided at different angular intervals on the lamp housing. Furthermore, the shape of the male members and the support areas on the mast flange and the corresponding shape of the plug-in positions and the contact surface on the lamp housing can also change. The additional securing elements, as previously described as a spring and as a rocker arm, can be replaced by other securing elements, for example by a simple Federsplint or other known fuse ^¬ medium.
