Description

The invention relates to a holding device with the features of the preamble of claim 1.

The invention further relates to a cover device for a holding device with the features of claim 9.

The invention further relates to a ceiling and / or wall lamp with a holding device and a cover device.

Holding devices and covering devices of the type mentioned are already known and are part of the prior art. Such holding devices often have adjusting devices which can be used, for example, to adjust a boom arranged on the holding device. A receptacle for a lighting device, for example in the form of an LED spot, is arranged on this boom, the position of which can be adjusted by moving the boom. Depending on the dimensions and mass of the boom or the lighting device arranged on it, the holding device must absorb high forces. These forces must be compensated for by the adjustment device, which is achieved in the prior art by means of massive adjustment devices. This massive construction contradicts a visually stimulating appearance. In addition, the adjustment of the boom using the massive adjustment device or holding device is often very complicated or difficult, which is felt to be very annoying, especially when working overhead with a holding device mounted on a building ceiling.

For example, in such an adjustment, tools are used that have to be held upside down or in another forced position in order to be able to open and close the adjustment device.

In addition, in the prior art, in many cases a cover device is placed over the set holding device in order to conceal the construction of the holding device and thus to produce a visually improved appearance. These cover devices also often have to be adapted in a complicated manner to the previously selected adjustment position of the boom of the holding device, which in turn is perceived as annoying for the user when working overhead or in a forced position. Covering devices often simply have recesses that are dimensioned large enough to be able to compensate for the movements of the holding device. However, through this large recess it is possible to see into the interior of the holding device, which is not conducive to the visual appearance.

Further holding devices for holding a lighting device go from FIG US 2006/06 19 91 A1 and the WO 2016/15 05 64 A2 emerge and the DE 296 14 497 U1 discloses a cover device for a holding device for holding a lighting device.

In general, it can be said that holding devices and cover devices for ceiling or wall lamps are uncomfortable to install due to the mounting location and that there is often no simplification of the attachment and the setting.

The object of the invention is to avoid the disadvantages described above and to provide an improved holding device, an improved covering device, an improved arrangement of a covering device and a holding device and an improved ceiling or specify wall lamp with such a holding device and cover device.

This is achieved in the holding device according to the invention by the features of claim 1.

In the case of the covering device according to the invention, this is achieved by the features of claim 9.

In the case of the ceiling or wall lamp according to the invention, this is achieved by the features of claim 13.

According to the invention it is provided that the adjusting device has at least two mutually movable components which have a first operating position in which the components can be brought into connection with one another in a purely form-fitting manner so that the boom can be fixed relative to the support element, and which have a second operating position in which the purely form-fitting positive connection of the at least two components to one another can be canceled, so that the boom can be pivoted about the main pivot axis relative to the support element, a simple and stable adjusting device is provided. Due to the form-fitting connection of the at least two components, the adjusting device can absorb high forces. The boom can be adjusted in its position relative to the support element by simply removing the form-fitting connection of the at least two components that can be moved relative to one another. The adjustment takes place quickly and without great effort, which is particularly advantageous when assembling in difficult situations.

According to the invention, it is provided that at least one actuating element is provided, via which the positive connection of an adjusting device can be established or canceled in order to adjust the position of the boom about the main pivot axis. The actuating elements can be operated without tools. The adjustment is uncomplicated, quick and easy.

The shape of the at least one actuating element makes its operation intuitively understandable for the user.

Since, in the present invention, the positive connection to the adjusting device is made by a plurality of interlocking teeth of at least one latching section and at least one positively corresponding adjusting latching section, large, interlocking surfaces are generated by the plurality of teeth. The surface pressure is thus reduced due to the large number of individual, simultaneously acting surfaces, which leads to a stable but also compact design of the adjusting device. Several interlocking teeth also make it possible to select many different positions of the boom. Frictional or non-positive connections often tend to yield under load, for example even if a longer period of time has passed. Environmental influences such as temperature changes, precipitation, wind, contamination or even birds that settle on the boom can lead to the position being adjusted after a certain time. Or if the holding device is attached, for example, to a dynamically loaded surface such as in a means of transport (e.g. a railway wagon) or the like, vibrations or shocks can cause the connection to loosen. A positive connection that comes into force ensures that this connection is always maintained and that the position is not unintentionally adjusted.

If the at least one adjustment latching section arranged on the adjustment device is formed by at least one ring gear segment with external toothing and the at least one locking section arranged on at least one locking element is formed by at least one ring gear segment with internal toothing, the engagement of the at least one locking section in the corresponding, At least one adjustment latching section is carried out by moving the at least one locking element, it is ensured that not only via the Toothing, but also via the ring gear segments with their outer shape and their inner shape, a positive connection is established. Thus, the outer contour of the circular, convex adjustment section engages in the inner contour of the corresponding, concave locking element. In addition, the toothing creates a stable, form-fitting connection. If the at least one locking element is moved by the actuation of the at least one actuating element in order to cancel or establish the form-fitting connection, the holding device is also adjusted quickly and conveniently.

It is advantageous if the intermeshing of the teeth of the at least one latching section and of the at least one adjusting latching section takes place in a direction parallel to the main pivot axis. A compact design can be achieved by moving along or parallel to this main pivot axis. The interlocking of the toothing does not take place radially, which would contribute to a larger design of the holding device, since the feed path would have to be taken into account. In the case of the invention, the adjustment and the movement of the interlocking of the toothing take place from the inside out of the holding device to the outside. The teeth are not inserted radially into one another but pushed axially into one another. This ensures a space-saving adjustment of the holding device.

According to the invention it is provided that the at least one actuating element is configured by a manually actuatable lever pivotably mounted between an open position and a closed position, the adjustment of the holding device takes place without tools. Due to the design as a lever, only a small amount of force has to be applied in order to separate the locking sections from one another. Furthermore, the position of the lever is used to identify the position in which the latching sections and the adjusting latching sections are located. If the latching sections are locked together, the lever of the actuating element is in a closed position. Is the latching open and the adjustment can are made, the actuator is in an open position.

If the at least one actuating element is held in the closed position by at least one energy storage device and can be moved into the open position by overcoming the force of the energy storage device, the adjustment device automatically locks when the actuation elements are no longer touched. The at least one actuating element is permanently held in the closed position by the restoring force of the energy store. It can thus also be ruled out that the user forgets to reset the actuating element into the closed position. Tightening a fastening means to lock the adjusting device is therefore not necessary, since the positive connection is automatically established by the spring force of the energy storage device as soon as the at least one actuating element is no longer actuated.

If the boom is rod-shaped and is firmly connected to part of the adjusting device, the adjusting device together with the fastening body and the at least one actuating element being covered by a covering device in the assembled state of the holding device, with only the boom protruding from the covering device at a section of the covering device , then one achieves a visually stimulating appearance of the adjustable holding device. The structure of the holding device is bent by the covering device. Only the boom protrudes from this. The holding device is protected from contamination and environmental influences by the covering device. In addition, the covering device protects the electrical devices located therein.

It is also advantageous that the support element is detachably connected to the fastening body via at least one fastening means, with relative rotation of the support element when the fastening means are released can be carried out to the fastening body and the position of the support element can be locked relative to the fastening body by fastening the at least one fastening means. Because the support element is movable relative to the fastening body, a large adjustment range can be covered with the adjustment via the adjustment device. The boom is therefore not only pivotable, but also rotatable about an axis of rotation on the holding device. In the case of ceiling mounting, the boom can thus be rotated about the vertical axis and pivoted about the horizontal axis.

It has been found to be particularly advantageous that the support has at least one support surface for a panel, the panel having a panel opening for the passage of an arm of the holding device, and the panel being displaceable relative to the support in the assembled state. All movements that are carried out on the holding device when the boom is adjusted can thus be compensated for via the displaceably mounted panel. In the assembled state, it is ensured that there is no view of the inside of the assembly device. The holding device is thus protected from environmental influences. There is no unsightly appearance because the holding device remains hidden.

Due to the movable mounting of the cover in the support, the setting of the position of the cover relative to the support takes place automatically as soon as the cover device is attached to the fastening body. This is done by leading the boom through the aperture. If the panel is moved along the arm together with the cover device, the position of the panel relative to the cover device is automatically adjusted via the support. No tools are required for this adjustment. This is achieved, among other things, in that the diaphragm is shifted relative to the support parallel to the plane of the support.

If the enveloping body is essentially cylindrical in shape, the circular base planes of the cylinder being open, the support being arranged in or on an opening and a cover device fastening section in or on the opposite opening, the assembly of the cover device is also simplified. The cover device fastening section is acted upon by a clip-like fastening, for example. Thus, the cover device only needs to be plugged on and automatically locks in its assembly position, while the panel automatically moves into its position. A visually stimulating shape of the cover is realized by the cylindrical configuration. The lower opening is used to accommodate the support, which in turn serves as a bearing for the panel. This creates a closed body in the assembled state.

It has been found to be advantageous that the support is essentially formed by a circular ring, the outer diameter of which essentially corresponds to the diameter of the enveloping body and the inner diameter of which is smaller than the outer diameter of the diaphragm. This creates a closed covering device without a gap. Even after the position of the boom has been changed, the larger diameter of the diaphragm as the inside diameter of the support ensures that no gap is produced in the covering device.

If the aperture is formed by an ellipse, the smallest diameter of the ellipse essentially corresponding to the diameter of the push-through bracket, the elliptical shape ensures that the cross-section of the bracket can be recorded by the ellipse even if the bracket is inclined.

In addition, it is advantageous if the diaphragm opening is arranged eccentrically in the diaphragm. The eccentric positioning of the diaphragm enables a larger adjustment range realized. If the aperture were to be located in the center of the aperture, a gap between the aperture and the support would arise if the aperture was adjusted over a wide range than in the case of an eccentric design, since the aperture can not only move linearly on the support, but only relative to the Can twist support. This rotation is forced by the eccentric arrangement of the aperture, so the larger surface section of the aperture is always rotated against the adjustment direction of the boom, which means that a larger adjustment range is covered by the aperture.

If the diaphragm rests on one side on the support surface of the support and the diaphragm is pressed on its opposite side by a counter bearing, preferably resiliently formed by the at least one actuating element, against the support surface of the support, the positive effect arises that even with a Blocking the holding device with the cover device, for example, in a not vertically downward direction, but in an inclined position or, for example, when mounting on a wall, the panel is always pressed against the support and cannot fall inward into the cover device or there is a gap between the support and the aperture forms. As already mentioned, this counter bearing is formed by the at least one actuating element. Thus, in the closed position of the at least one actuating element, a connection between the counter bearing and the panel is established. If the counter-bearing is designed to be resilient, which can be achieved, for example, by the choice of material for producing the at least one actuating element, a preload and a constant pressure of the counter-bearing against the diaphragm result. The at least one actuating element can be manufactured at least in sections or also completely from an elastic and resilient plastic or, for example, from a spring steel, in order to produce the resilient effect. It is important that, due to the different positioning options of the holding device and the cover device arranged on it, the panel in Assembly position is always pressed against the support so as not to leave a gap between the support and the panel.

A ceiling or wall lamp with a holding device and a covering device is advantageous, since the adjustment of the holding device is very simple and the adjustment of the covering device is also carried out automatically. This is also achieved that when the boom is adjusted by the diaphragm mounted on the support and the diaphragm opening located in the diaphragm, the diaphragm can be displaced by the boom into the position relative to the support.

A ceiling or wall lamp with a holding device and a cover device as described above is easy to assemble and easy to adjust, especially when the ceiling or wall lamp is fastened in a forced position, the advantages of the holding device and the cover device can be particularly evident.

In addition, the holding device is made very stable and yet compact due to its positive-locking adjustment device, which extends the field of application of the ceiling or wall lamp with a corresponding holding device.

Fig. 1 shows the holding device 1 in an exploded view together with the cover device 23. The fastening body 2 is used to fasten the holding device 1 and also the cover device 23 to a surface, in particular a building wall or building ceiling. An attachment to an object such as a piece of furniture or something similar can of course also be provided. The fastening body 2 is fastened via a connection section 4 through which fastening means such as screws can be passed in order to be able to establish the connection to the surface. In addition, the fastening body 2 has at least one cable opening 35, which enables the power supply required for the lighting device 101 to be passed through. At least one fastening means 13, preferably in the form of a screw, is located on the fastening body 2 in order to be able to accommodate the support device 3. The locking means 12, which is pressed against the support device 3 via the at least one fastening means 13, is used for this purpose. Thus, by releasing the at least one fastening means 13, the locking means 12 can be loosened in order to be able to adjust the position of the support device 3 relative to the fastening body 2. This is a rotation of the support device 3 relative to the fastening body 2. After the adjustment has been made, the support device 3 can be locked in its position by tightening the at least one fastening means 13 or the corresponding fastening means 14 arranged thereon. The adjusting device 10 is used in the supporting device 3. This is about a main pivot axis HSA (in Figures 2a and 2b shown) pivotably mounted in the support device 3. This pivotable mounting takes place via the at least one pivot bearing pin 42, which is preferably arranged in the support device 3. At least one actuating element 4a, 4b is hinged rotatably on the support device 3. This moves as a lever at one end rotatably arranged on the support device 3 between an open position and a closed position. This movement between the open position and the closed position is supported by at least one guide element 6, at least one energy storage mechanism 5 being arranged on the actuating element 4a, 4b in such a way that it remains in its closed position.

The actuating element 4a, 4b is designed as a lever and at one end has a counter-bearing 46 which, in the closed position of the actuating element 4a, 4b, presses the cover 19 against the support 22. The at least one locking element 8a, 8b is coupled to the movements of the at least one actuating element 4a, 4b. If the at least one actuating element 4a, 4b is brought into an open position, the at least one locking element 8a, 8b is pressed into an open position and the positive fit between the at least one locking element 8a, 8b and the adjusting device 10 is canceled. The form fit is established via the at least one latching section 9a, 9b and the corresponding adjusting latching section 11a, 11b. The boom 18 is connected by a bearing pin 15 to a bearing element 7, which in turn is provided for attachment to the adjusting device 10. The bearing element 7 is connected to the adjusting device 10 via bearing screws 16. A direct screw connection or connection of the boom 18 to the adjusting device 10 can, however, also take place.

The boom 18 is essentially tubular and therefore has a cable guide 33. The power supply up to the lamp fastening section 31 can take place through this cable guide 33. If, for example, a transformer is required for the lighting device 100, it can be fastened to the receiving section 32 of the locking means 12, for example. The locking means 12 is fastened to the fastening body by means of fastening means 13. For example, the Corresponding fastening means 14 in the form of nuts which are placed on the fastening means 13 in the form of screws.

The covering device 23 consists essentially of the components of the diaphragm 19, the diaphragm opening 20, the enveloping body 21, the support 22. The substantially cylindrical enveloping body 21 contains the support 22, which is configured circular. This takes up the screen 19 on the inside of the enveloping body 21.

In the assembled state, the counter-bearing 46 of the at least one actuating element 4a, 4b presses against the cover 19 and this therefore against the support 22. If the boom 18 is adjusted relative to the fastening body 2 by the adjustment device 10, this movement is compensated by the cover 19. For this purpose, the eccentric positioning of the aperture 20 is very advantageous. Furthermore, it is advantageous to design the diaphragm shape as an ellipse so that the cross section of the boom 18 is better adapted as soon as the longitudinal extension of the boom 18 is in an inclined position or in a position deviating from an orthogonal position relative to the diaphragm 19.

At the front end of the boom 18 is the end piece 30 for receiving the lamp holder head 28. The lamp holder head 28 is fastened to the end piece 30 by screwing, welding or some other type of fastening. Arranged on the lamp holder head 28 there is at least one lamp holder axis 27, via which the lamp holder head 28 is pivotably mounted. The lamp holder head 28 also has a cable bushing 33.

Fig. 2a shows how the at least one actuating element 4a, 4b remains in a closed position. This closed position is achieved by the at least one energy store 5, which is arranged along the at least one guide element 6. In this case, the energy store 5 is a Compression spring. The compression spring acts directly against the at least one locking element 8a, 8b movably mounted on the support device 3. The toothing of the at least one locking element 8a, 8b thus engages in the toothing of the adjusting device 10. This creates the positive connection that holds the boom 18 in its position. The form-fitting connection is established by the at least one adjusting latching section 11a, 11b and the at least one corresponding latching section 9a, 9b. In the upper area of the Fig. 2a it can be seen that at least one cover fastening element 41 is arranged on the fastening body 2 and is used to fasten the cover device 23. The attachment is in the Figures 3a, 3b can be seen in detail.

For better operability, the at least one actuating element 4a, 4b has at least one recessed grip which is adapted to the ergonomics of a finger. The cover fastening devices 41 are designed by resilient elements - for example made of spring steel. These engage in a fastening section of the cover device 23 in a form-fitting manner.

The boom 18 is connected to the bearing element 7, which in turn is connected to the support element 3 via at least one pivot bearing pin 42. The boom 18 is thus rotatable via the main pivot axis HSA and is arranged on the support device 3. Due to the positive connection between the latching sections 9a, 9b and the adjusting latching sections 11a, 11b, pivoting of the boom 18 is not possible.

The Figure 2b shows how the at least one actuating element 4a, 4b is brought into the open position. In the open position of the at least one actuating element 4a, 4b, the at least one locking element 8a, 8b is pressed against the at least one energy store 5 and along the at least one guide element 6 in the direction of the center of the adjusting device 10.

The at least one latching section 9a, 9b is no longer in a form-fitting connection with the adjusting latching section 11a, 11b. Adjustment of the boom 18 is thus possible. If it is also necessary to rotate the boom 18 relative to the fastening body 2, this can be done by loosening the at least one fastening means 13, 14 and thus releasing the clamping by the locking means 12 against the support device 3. After the adjustment has been made, the locking can be restored by tightening the at least one fastening means 13, 14.

Fig. 3a shows the holding device 1 in a side view with a section. The latching section 9 engages positively in the adjusting latching section 11. A positive connection is thus established. In the case of the Fig. 3a the boom 18 is set substantially vertically. In this case, the aperture 20 is also located centrally in the middle of the cover device 23. There is thus no gap between the aperture 19 and the support 22. The interior of the holding device 1 remains hidden. In addition, it can be seen how the cover fastening section 44 is held via the at least one cover fastening element 41. The cover fastening section is designed in the form of a radial groove in the interior of the enveloping body 21.

Figure 3b shows the adjusted boom 18. The boom 18 has been adjusted about the main pivot axis HSA. After the adjustment, the latching sections 9, 11 have returned to a form-fitting connection. The adjustment remains upright. The diaphragm 19 compensates for the path of the boom 18 in that it is carried along through the diaphragm opening 20.

Figure 4a shows the same position as the Fig. 3a of the boom, only in the external view and in a perspective view. The boom 18 protrudes while perpendicularly out of the covering device 23. The elliptical aperture 20 is in the center of the support 22.

The Figure 4b shows the degrees of freedom F and the degrees of freedom D of rotation of the panel 19. Depending on the position of the boom 18, the panel can be guided over the degrees of freedom F, D in the interior of the enveloping body 21 and moved by the support 22. The eccentric positioning of the diaphragm opening 20 in the diaphragm 19 or the elliptical design of the diaphragm opening 20 are advantageous here.

Figure 5a shows a section through the lamp fastening section 31. The lamp fastening section 31 is rotatably arranged on the lamp holder head 28. In this exemplary embodiment, this is done, for example, by means of a screw that serves as the lamp holder axis 27.

Thus, the lamp holder or the lamp fastening section 31 is mounted pivotably about the lamp pivot axis LSA. The inhibiting pieces 26 - designed as leaf springs in this example - prevent an unintentional adjustment of the lamp mounting section 31 Figure 5b shows how that Figure 5a the lamp mounting portion 31, which has been adjusted relative to the arm 18.

A sleeve 25, which serves as a cover for the lamp attachment section 31, has a sleeve cutout 45 in order to increase the degree of freedom of the sleeve 25 relative to the arm 18. That is also in the Figure 6b evident. The boom is retracted into the cuff cutout 45 of the cuff 25. The Figure 6a shows how the sleeve 25 is positioned relative to the boom 18 in the neutral position. The lamp holder head 28 can as in Figures 5a to 6b shown, so be adjusted relative to the boom 18.

Figure 7a shows the locked latching section 9 in a form fit with the adjusting latching section 11 in a perspective view. At least one Actuating element 4 is in the closed position. In this example, the boom 18 is orthogonal relative to the fastening body 2.

Figure 7b shows how the at least one fastening element 4 was brought into an open position. The adjusting latching section 11 thus no longer has a positive connection to the latching section 9. An adjustment of the arm 18 relative to the fastening body 2 can now take place as long as the at least one actuating element 4 remains in the open position.

The Fig. 1 , 3a , 3b , 4a, 4b It can be seen that due to the dimensioning of the diaphragm 19 with its outer diameter and the diaphragm opening 20 arranged eccentrically in the diaphragm 19, or due to the smaller inner diameter of the support 22 in comparison to the external diameter of the diaphragm 19, the diaphragm 19 is not set relative to the support 22 in any setting a gap is created between the diaphragm 19 and the support 22. Furthermore, the aperture 20 is essentially completely filled by the diameter of the arm 18, whereby it is not possible to look into the interior of the cover device 23. The interaction between the dimensioning of the diameter of the boom 18, together with the dimensioning of the aperture 19 and the eccentrically arranged, elliptical aperture 20 therein, together with the dimensioning of the inner diameter of the support 22, which is located in an enveloping body 21, thus creates a self-contained cover device 23, which is also adjustable. A permanent overlap of the edges of the outer diameter of the diaphragm 19 is thus ensured by the annular support 22 in the assembly position.

Figure 7c shows that the boom 18 has been brought into the desired position and that at least one actuating element 4 has been released. The positive connection between the latching elements 9, 11 is thus created.

Figure 8a shows the adjusting device 10 with two adjusting latching sections 11a, 11b. These are offset to one another in order to achieve a smaller pitch. This is done in the Figure 8b shown in detail.

The angle of the tooth pitch, the tooth angle α, is 10 ° in this exemplary embodiment. At the adjustment latching section 11a, there is thus a tooth pitch at a tooth angle a. The opposite adjustment latching section 11b also has a tooth pitch of a tooth angle α, only this pitch is offset by half a tooth angle a, i.e. a / 2, to the teeth on the adjustment latching section 11a. Thus, there is no minimum division of the tooth angle α during the adjustment on the adjusting device 10, but a division of a / 2 (for example a = 10 °, a / 2 is 5 °). A smaller and more precise adjustment of the boom 18 is thus possible if two adjustment latching sections 11a, 11b arranged offset from one another are implemented. Of course they have to be in the Figures 9a, 9b corresponding latching sections 9a, 9b shown are adapted accordingly to this division.

The Figure 9a shows how the latching section 9b engages and establishes a positive connection. The opposing latching section 9a with the adjusting latching section 11a is not in a form-fitting engagement since its division does not correspond to the division of the latching section 9b. Furthermore, in the Figure 9a it can be seen how the counter bearing 46 presses against the diaphragm 19 and thus closes it off with the support 20 without a gap.

The division of the adjusting latching section 11b thus comes into force. The Figure 9b shows the opposite case. The adjustment latching section 11b is not in any form-fitting connection with the latching section 9b. Thus, a smaller division can be achieved via two latching sections 9a, 9b, 11a, 11b that can be operated independently of one another.
