Definitions
- the invention relates to a suspension device for suspending and lighting prints, paintings and other objects to be exposed to view.
- the invention furthermore relates to a lighting device and a live conducting rail for use with such a suspension device.
- the invention further relates to a suspension element for use with such a suspension device and to a ceiling rail for arranging a suspension element and/or a lighting device.
- the paintings can then be movably attached to the suspension rail with the help of suspension elements, which can have the shape of a hook or a clamping block, and to which, for example, a suspension wire or suspension rod for the painting can be attached.
- suspension elements can have the shape of a hook or a clamping block, and to which, for example, a suspension wire or suspension rod for the painting can be attached.
- a lighting device is attached to the suspension, for example to the clamping block and/or to the suspension wire.
- the lighting device is movable independently of the objects to be suspended.
- the conducting rail being live, no loose power cables are necessary.
- the lighting device can be arranged at every desired place in the conducting rail, and the tension means will push the clamping means against the holding means of the conducting rail, and the contact part of the lighting device against the conducting strip, so that a good electric contact is established.
- a preferred embodiment of the device is described in claim 2.
- the clamping plate is easily inserted at the desired place in the conducting rail, after which the compression spring, which was somewhat pushed in, can expand and will push the contact part against the live strip and the clamping plate against the holding means of the conducting rail.
- the suspension device without conducting rail can easily be attached to the wall by, for example, screws. Then the separate conducting rail can be easily placed in the receiving space and thus conceal the fixing points.
- the longitudinal opening of the conducting rail can be directed upwards, so that the lighting device will project above the conducting rail.
- the longitudinal opening of the conducting rail can also be directed sidewards, so that the lighting device does not have to project above the conducting rail.
- the suspension device can be arranged near or against a ceiling or the like.
- Claim 4 describes an advantageous embodiment of the suspension device and conducting rail, in which the conducting rail, which is open sidewards, is easily attached in the receiving space of the suspension device by inserting and snapping it in.
- the kind of material and the dimensions of the device have been chosen, such that at least one of the walls or legs with cam or recess is sufficiently flexible.
- Claim 7 describes a preferred embodiment of the clamping plate, by means of which the lighting device can be put into the U-shaped conducting rail from the front, during which the compression spring is compressed slightly, after which the grip with the clamping plate only has to be turned a quarter of a turn. Then the grip can be released and the compression spring will push the clamping plate against the lips of the conducting rail, and the contact part of the lighting device against the conducting strip. The clamping plate cannot be turned back by accident because of the slots in the clamping plate, which fit over the lips of the conducting rail.
- a preferred embodiment of the suspension rail of the device is described in claim 10.
- a suspension element such as a hook, can easily be arranged, while the front panel hides the suspension elements from view.
- the device comprises a tongue as described in claim 11.
- a cord can be laid on the tongue which is connected to a burglar alarm, without the cord hampering the suspension elements in the suspension rail.
- the cable does not slide from the tongue; in the case of the upward slanting tongue the beaded edge is not necessary.
- a transformer connection can easily be included in the device, it being for instance also possible to hide the transformer connection from view with the covering according to claim 13.
- a paper clamp is arranged in the suspension rail of the device, so that paper and the like can be rapidly and removably attached.
- a lighting device is described, which is particularly suitable for use with a suspension device as described above.
- Claim 17 describes a live conducting rail, which as separate lighting rail is very suitable for using the lighting device of claim 16, if no objects need to be hung up.
- a ceiling rail for placing ceiling plates of a system ceiling is described, with a receiving space, such that, for example, a lighting device such as the lighting device of claim 14, or, for example, a suspension element for an object to be suspended, can be arranged in the ceiling rail.
- At least one of the walls of the suspension rail which is directed downward can comprise a portion which is directed towards the other wall, which offers a supporting plane for the suspension elements. It is thus achieved that a clamping block, for example, can easily be inserted into the suspension rail and remains in position under the action of gravity.
- At least one supporting plane is at an oblique angle of, preferably 45°.
- the suspension elements have a thickness, such that they can be inserted in the suspension rail between the walls with the supporting planes, and a breadth, such that after insertion and after turning a quarter turn they can rest against the supporting planes.
- a suspension element does not have to be inserted from an end face in the suspension device, after which it has to be moved over a distance, but it can be inserted in the suspension rail at any desired place and after turning a quarter turn it can rest.

- the suspension and conducting rail is substantially E-shaped, with an upper leg 12, a middle leg 13 and a lower leg 14.
- the lower leg 14 comprises a raised edge 15 for the suspension element 28.
- the middle leg comprises a front panel 16.
- the live conducting rail is formed by the upper part of the E.
- the holes 20 are arranged so as to attach the device with screws to the wall 2.
- the upper part which is U-shaped in cross section, is open sidewards.
- the separate part 4 of the conducting rail is arranged in this U.
- Figure 1A shows this separate part 4. It is substantially U-shaped in cross section, with walls 22, cheeks 23 facing each other and inward directed lips 24.
- the conducting strip 6 and the current insulating profile 7 are contained in this portion 4. After being attached to the wall the portion 4 is inserted into the upper part and fixed with, for example, double-sided adhesive tape.
- Figure 1 shows the attached part 4 with the contact part 26 of the lighting device 25.
- the contact part 26 comprises a spherical portion 9, which is connected to a thickening on the support pipe 30 to the lamp part 27 with the help of an insulating portion 10, in which a threaded portion 11 is rotatable and slidable on the longitudinal support pipe 30, which threaded portion 11 is screwed into a clamping plate 8.
- FIG 2 shows another embodiment of the suspension device.
- the conducting rail is the same and the separate part 4 has therefore been omitted.
- the front panel 16 extends downward and at the same time slants increasingly backward.
- the lower edge thus forms a supporting plane for the suspension element 31, which for that reason only has to have a bevel on one corner.
- the back wall of the suspension rail can have a lip 32 with a horizontal supporting plane as additional support for the suspension element 31. This additional lip 32 is not necessary, however.
- the suspension element 31 can be inserted in between the front and the rear wall in the suspension rail and after a quarter turn can rest on the lower edge of the front panel 16 and, if present, on lip 32.
- Figure 3 shows a further embodiment of the suspension device.
- the conducting rail is the same and for that reason the separate part 4 thereof has been omitted.
- the front panel 16 of the suspension rail comprises an additional edge 17, and this edge and the rear wall of the suspension rail comprise bevelled lips 18 and 19.
- Figure 3A shows the corresponding suspension element 29 in side view; it can be inserted through the opening between the lips and after a quarter turn can rest on the bevelled lips 18 and 19.
- Figure 4 shows another embodiment, in which the separate part 4 of the conducting rail can be arranged with the opening upwards.
- the upper edge 21 prevents that the moment which is caused by the lighting device, pulls the separate part loose.
- the suspension rail can be executed according to figure 1 or according to figure 2 as desired.
- Figure 5 shows the suspension and the conducting rail 3, the conducting strip 6 and the current insulating profile 7 in perspective, as is shown in cross section in figure 1.
- Figure 6 shows the embodiment according to figure 3 in perspective.
- Figure 7 shows the lighting device 25 with the contact part 26 and a lamp part 27.

- the lamp part 27 is executed in a known manner.
- Figure 8 shows a possible dimensioning for the separate portion 4 of the live conducting rail.
- This portion is substantially U-shaped in cross section.
- a suspension element such as a suspension element 28 over the raised edge 15, such as in figure 1, or a suspension element 29 between the slanting lips 18 and 19 of the suspension rail, such as in figure 3.
- lighting device 25 can be moved with the help of the contact part 26 in the live conducting rail by screwing the screw thread portion 11 slightly out of the clamping plate 8, sliding the contact part 26 in the conducting rail, and then screwing the screw thread portion tight again, as a result of which the clamping plate will rest on the lips 24 of the conducting rail, and the spherical portion 9 will be pushed against the conducting strip 6.
- Arranging a lighting device in the conducting rail is easy, in that the clamping plate 8 is narrower than the opening in the conducting rail.
- the clamping plate can thus be inserted through the opening of the conducting rail, and after a rotation through 90° can rest against the lips of the conducting rail.
- FIG 10 shows further embodiment of the suspension device according to the invention, indicated by 101, which is screwed with screws to the wall 102.
- the suspension device 101 comprises a lower leg 109 with a raised edge 110 for the suspension element 28, a horizontal tongue 106 with a beaded edge 107, and in addition a horizontal ledge 105 and an upper leg 140 with a downward directed edge 121 with an inward directed lip 122 for receiving a separate live conducting rail 104.
- the live conducting rail 104 is shown separately in figure 11A and is substantially U-shaped in cross section, having cheeks 115 facing each other along its opening, each of which has an inwardly directed lip 116.
- the legs 118 of the live conducting rail both have on their inner side a longitudinal cam 117 for receiving and securing an insulating strip 111, which is also substantially U-shaped and has inwardly directed cams 112 along its edges, so as to secure a conducting strip 113, which is also substantially U-shaped in cross section and has rounded edges 114. This can be seen clearly in figure 12.
- the conducting rail is constructed to receive a lighting device, the connecting end 129 of which is shown in figure 10.
- the support pipe 30 and the lamp part 27 can be executed in accordance with figure 7.

- the front panel 145 is bent downward to the back, and this front panel has an inwardly directed tongue 146 with beaded edge 147.
- Figure 12A shows an embodiment which is similar to the embodiment of figure 12, but which has a front panel 144 and a tongue 106 with beaded edge 107, which are taken from the embodiment of figure 10.
- the short upper leg 140 with a downwardly projecting lip 141 can be clearly seen, behind which the live conducting rail 104 has to hook.
- a wedge-shaped slot 143 is arranged in the middle leg 142, in which a wedge-shaped cam 120 on the base 119 of the live conducting rail 104 (vide figure 11A) has to snap.
- Such a slot is also arranged in the rear wall of the suspension and conducting rail 103 of the embodiment of the suspension device according to figure 10, vide figure 11.
- Figures 13 and 13A show the substantially rectangular clamping plate 132 which is provided in the middle with a hole 150 for said attachment to the grip 131 and which is provided with slots 151 along its short edges for cooperation with the lips 116 on the cheeks 115 of the live conducting rail 104.

- One of the holes 162, 162' is for the power cable to the transformer; a power cable in the other hole can lead the current to a coupling block of another conducting rail.
- Each power cable should be clamped with the help of two terminal screws through screw holes 163 or 163'.
- Transformer connection 160 has a current transferring plate 164 which has to be placed against the legs of the U-shaped conducting strip 113, and transformer connection 165 has a current transferring plate 167 which has to be placed against the lips on the cheeks of the conducting rail 104. Between these an insulating plate 168 of, for example, Pertinax is arranged. In the current transferring plate 167 screw holes are arranged through which set screws 169 should be screwed for pushing the current transferring plates against the conducting strip 113 and the lips of the conducting rail, respectively.
- the transformer connections 160 and 165 are designed so that they can be inserted so that they just fit into the conducting rail 104, if the conducting strip 113 and the insulating strip have be removed there.
- Figure 15A shows a cross section of the live conducting rail at the location of the current transferring plates 164 and 167 and figure 15B shows a perspective view of the outer end of the live conducting rail 104 in which the transformer connections are accommodated.
- Figure 16 show a ceiling rail for placing ceiling plates 171 of a system ceiling, the ceiling strip 170 having two edges 172 projecting to both sides, on which the ceiling plates 171 rest.
- the ceiling strip 170 has in its upper portion a synthetic insulating strip 173 provided with holes 174 to suspend the ceiling strip by hooking.
- the longitudinal body of the ceiling strip 170 has a receiving space in the shape of a reversed U, with cheeks 175 facing each other along the opening of the U and cams 176 facing each other halfway along the height of the U.
- an insulating strip 111 and a conducting strip 113 can be arranged in the U-shaped receiving space, which are secured by the cams 176.
- a covering can be snapped in the receiving space, analogous to the coverings 155 and 157 for the suspension device.
- the figures 17 and 17A show another embodiment of the suspension device 203 and live conducting rail 204.
- the conducting rail 104 of figure 11A the conducting rail 204 is U-shaped in cross section, with base 219, legs 218, cheeks 215, lips 216 and cams 217.
- the upper leg has a wedge-shaped cam 220 on its outer side.
- the suspension device 203 has a lower leg 209 with raised edges 210.
- the suspension device further has an upper wall 206 and a middle wall 205, onto which a front panel 208 is attached. On the inwardly directed side of the upper wall 206 a wedge-shaped recess 221 is arranged, which corresponds to the wedge-shaped cam 220 on the conducting rail 204.
- the conducting rail 204 can now easily be attached in the suspension rail by sliding the rail between the walls 205 and 206.
- the cam 220 then "snaps" into the recess 221.
- the upper leg and wall will have to move apart slightly, which can be realized by a correct dimensioning of cam, leg and wall, so that the upper leg and/or wall is sufficiently flexible.
- Figure 17 also shows that on the rear wall of the suspension device 203 two ledges 207 are arranged. Together with the rear wall of the suspension device 203 and the base 219 of the conducting rail 204 the ledges 207 form a cable cavity, through which, for example a power cable for other purposes can be lead. Because a tongue such as tongue 106 is not present in figure 10 the suspension device is not so high.
- Figure 12 also shows that in the suspension rail of a suspension device with a front panel which extends downward to the rear, a paper clamp can be arranged which has the shape of a roll 180 which is annular in cross section behind which paper and the like can be slid and clamped.
- the roll can also be polygonal.
- the lighting device can easily be placed in the conducting rail.
- the clamping plate 132 By grasping the connecting end 129 by the grip 131, the clamping plate 132 can be rotated such that the clamping plate 132 can be inserted between the cheeks 115 of the live conducting rail 104.
- the contact part 133 abuts against the conducting strip 113, and when the grip 131 is pushed further the compression spring 135 is pushed in.
- the clamping plate 132 can be pushed in so far that it is located beyond the lips 116 on the cheeks 115 of the live conducting rail 104, and then the grip 131 with the clamping plate 132 can be rotated a quarter of a turn.
- the compression spring 135 pushes the grip to the outside, and the clamping plate 132 is pushed against the lips 116 of the live conducting rail.
- the clamping plate 132 having slots 151 which correspond to the lips 116, the lips 116 will fall into the slots 151, as a result of which the clamping plate 132 is locked against undesired rotation of the grip 131, so that as a consequence the lighting device will not come off the suspension device by accident.
- the distance between the legs of the U of the conducting strip correspond to the diameter of the contact part 133 of the lighting device. Due to this the contact part 133 will not be able to slide transversely to the conducting strip so that the contact part 129 will not tilt downwards and the lighting device will not come into accidental contact with the object exposed to view, as a result of the tilting.
- the conducting rail is now suited for supplying a low voltage current, for example 12 Volt, to the lighting device, for example, a halogen lamp.
- the current is then supplied by the conducting strip and passes through the contact part and a wire in the lighting device to the lamp.
- the current is discharged through the outside of the lighting device and passes through the clamping plate by way of the clean scraped lips to the outside of the separate conducting rail for closing the circuit.
- Figures 1, 2, 3, 3A and 10 show a suspension element 28, 29 and 31, the suspension block comprising a hole with an widened upper part, through which a thread element 33 with a thickening at its upper end projects. Because of this the suspension element can take the weight of an object to be exposed to view, without it being necessary to use a screw for clamping the thread element 33 in the suspension block. The thickening is clamped somewhat in the suspension block so that when lifting up the thread element the suspension block will also be lifted up, which simplifies the moving of the suspension element in the suspension device or the removal of the suspension element from the suspension device.
- the thickening of the thread element 33 can be formed together with the thread element and be cylindrical or have the shape of a reversed cone; other forms are also possible.
- the widening of the hole in the suspension block should also have a corresponding shape.
- the thread element can be a wire or a rod.
- the thickening separately by inserting a flexible thread element through the hole and then through a sleeve, bending the end and reinserting it in the sleeve, and then pinching the sleeve.
- the loop which projects above the sleeve can then be removed, and the sleeve be accommodated in the widening of the hole in the suspension block.

Abstract
Description
- The invention relates to a suspension device for suspending and lighting prints, paintings and other objects to be exposed to view.
- The invention furthermore relates to a lighting device and a live conducting rail for use with such a suspension device.
- The invention further relates to a suspension element for use with such a suspension device and to a ceiling rail for arranging a suspension element and/or a lighting device.
- Hanging up paintings and the like with the help of a suspension rail is known. The paintings can then be movably attached to the suspension rail with the help of suspension elements, which can have the shape of a hook or a clamping block, and to which, for example, a suspension wire or suspension rod for the painting can be attached. For lighting the suspended painting, a lighting device is attached to the suspension, for example to the clamping block and/or to the suspension wire.
- This has the disadvantage that the lighting device cannot be placed or moved independently of the painting. In addition, the lighting device applies force to the clamping block and/or to the suspension wire.
- Another disadvantage is that the power cable leading to the lighting device is in view, which, near the painting, is not such an attractive sight. There is also the possibility that when hanging up the painting the cable gets tangled up with the suspension wire.
- It is an object of the invention to provide a suspension device in which the lighting device can be moved independently of the objects to be exposed to view and in which the power supply to the lighting device is concealed.
- This object is achieved by the suspension device according to claim 1.
- With this it is achieved that by means of the conducting rail the lighting device is movable independently of the objects to be suspended. On account of the conducting rail being live, no loose power cables are necessary. With the help of the clamping means and the tension means the lighting device can be arranged at every desired place in the conducting rail, and the tension means will push the clamping means against the holding means of the conducting rail, and the contact part of the lighting device against the conducting strip, so that a good electric contact is established.
- A preferred embodiment of the device is described in claim 2. By means of the grip, the clamping plate is easily inserted at the desired place in the conducting rail, after which the compression spring, which was somewhat pushed in, can expand and will push the contact part against the live strip and the clamping plate against the holding means of the conducting rail.
- An advantageous embodiment of the live conducting rail is described in
claim 3. By executing the conducting rail as separate U-shaped part, the suspension device without conducting rail can easily be attached to the wall by, for example, screws. Then the separate conducting rail can be easily placed in the receiving space and thus conceal the fixing points. The longitudinal opening of the conducting rail can be directed upwards, so that the lighting device will project above the conducting rail. The longitudinal opening of the conducting rail can also be directed sidewards, so that the lighting device does not have to project above the conducting rail. As a consequence, the suspension device can be arranged near or against a ceiling or the like. -
Claim 4 describes an advantageous embodiment of the suspension device and conducting rail, in which the conducting rail, which is open sidewards, is easily attached in the receiving space of the suspension device by inserting and snapping it in. In addition, the kind of material and the dimensions of the device have been chosen, such that at least one of the walls or legs with cam or recess is sufficiently flexible. - A further elaboration of the conducting rail is described in the
claims -
Claim 7 describes a preferred embodiment of the clamping plate, by means of which the lighting device can be put into the U-shaped conducting rail from the front, during which the compression spring is compressed slightly, after which the grip with the clamping plate only has to be turned a quarter of a turn. Then the grip can be released and the compression spring will push the clamping plate against the lips of the conducting rail, and the contact part of the lighting device against the conducting strip. The clamping plate cannot be turned back by accident because of the slots in the clamping plate, which fit over the lips of the conducting rail. - In
claim 8 an advantageous embodiment is described, by means of which one or more cable cavities become available, through which, for example, power cables for other purposes can be lead through invisibly. - In
claim 9 another embodiment of the lighting device is described. - A preferred embodiment of the suspension rail of the device is described in
claim 10. Around the raised edge a suspension element, such as a hook, can easily be arranged, while the front panel hides the suspension elements from view. - According to an advantageous embodiment the device comprises a tongue as described in
claim 11. For example a cord can be laid on the tongue which is connected to a burglar alarm, without the cord hampering the suspension elements in the suspension rail. On account of beaded edge the cable does not slide from the tongue; in the case of the upward slanting tongue the beaded edge is not necessary. - In the device according to claim 12 a transformer connection can easily be included in the device, it being for instance also possible to hide the transformer connection from view with the covering according to
claim 13. - In the device according to claim 14 a paper clamp is arranged in the suspension rail of the device, so that paper and the like can be rapidly and removably attached.
- An advantageous embodiment of a suspension element, which is suitable for use on or against a suspension device as is described above, is described in
claim 15. - In claim 16 a lighting device is described, which is particularly suitable for use with a suspension device as described above.
-
Claim 17 describes a live conducting rail, which as separate lighting rail is very suitable for using the lighting device ofclaim 16, if no objects need to be hung up. - In the
claims 18 and 19 a ceiling rail for placing ceiling plates of a system ceiling is described, with a receiving space, such that, for example, a lighting device such as the lighting device ofclaim 14, or, for example, a suspension element for an object to be suspended, can be arranged in the ceiling rail. - If the longitudinal opening for the suspension rail is directed downward, at least one of the walls of the suspension rail which is directed downward can comprise a portion which is directed towards the other wall, which offers a supporting plane for the suspension elements. It is thus achieved that a clamping block, for example, can easily be inserted into the suspension rail and remains in position under the action of gravity.
- Advantageously at least one supporting plane is at an oblique angle of, preferably 45°. When using one oblique supporting plane and one vertical supporting plane, and when using two oblique supporting planes an additional clamping effect on an arranged suspension element is established, so that it cannot be moved so easily by accident.
- In an advantageous manner the suspension elements have a thickness, such that they can be inserted in the suspension rail between the walls with the supporting planes, and a breadth, such that after insertion and after turning a quarter turn they can rest against the supporting planes. In this way a suspension element does not have to be inserted from an end face in the suspension device, after which it has to be moved over a distance, but it can be inserted in the suspension rail at any desired place and after turning a quarter turn it can rest.
- The invention will now be described by way of example with reference to a number of preferred embodiments as shown in the accompanying drawings. These exemplary embodiments do not limit the invention; other embodiments are possible.

- Figure 16 shows a perspective view of a ceiling rail.
- The figures 17 and 17A show another embodiment of the suspension device with the corresponding conducting rail according to the invention.
- Figure 1 shows the suspension device indicated by 1, which is screwed to a wall 2 with the help of screws through
holes 20 in the upper part of the device. The suspension device 1 comprises a suspension and conductingrail 3 which forms a whole, a conductingstrip 6, a currentinsulating profile 7, asuspension element 28 and acontact portion 26 of alighting device 25. The suspension and conducting rail is substantially E-shaped, with anupper leg 12, amiddle leg 13 and alower leg 14. Thelower leg 14 comprises a raisededge 15 for thesuspension element 28. The middle leg comprises afront panel 16. - The live conducting rail is formed by the upper part of the E. In this upper part the
holes 20 are arranged so as to attach the device with screws to the wall 2. The upper part which is U-shaped in cross section, is open sidewards. Theseparate part 4 of the conducting rail is arranged in this U. - Figure 1A shows this
separate part 4. It is substantially U-shaped in cross section, withwalls 22,cheeks 23 facing each other and inward directedlips 24. The conductingstrip 6 and the current insulatingprofile 7 are contained in thisportion 4. After being attached to the wall theportion 4 is inserted into the upper part and fixed with, for example, double-sided adhesive tape. - Figure 1 shows the attached
part 4 with thecontact part 26 of thelighting device 25. Thecontact part 26 comprises aspherical portion 9, which is connected to a thickening on thesupport pipe 30 to thelamp part 27 with the help of an insulatingportion 10, in which a threadedportion 11 is rotatable and slidable on thelongitudinal support pipe 30, which threadedportion 11 is screwed into aclamping plate 8. - Figure 2 shows another embodiment of the suspension device. The conducting rail is the same and the
separate part 4 has therefore been omitted. Thefront panel 16 extends downward and at the same time slants increasingly backward. The lower edge thus forms a supporting plane for thesuspension element 31, which for that reason only has to have a bevel on one corner. The back wall of the suspension rail can have alip 32 with a horizontal supporting plane as additional support for thesuspension element 31. Thisadditional lip 32 is not necessary, however. Thesuspension element 31 can be inserted in between the front and the rear wall in the suspension rail and after a quarter turn can rest on the lower edge of thefront panel 16 and, if present, onlip 32. - Figure 3 shows a further embodiment of the suspension device. The conducting rail is the same and for that reason the
separate part 4 thereof has been omitted. Here thefront panel 16 of the suspension rail comprises anadditional edge 17, and this edge and the rear wall of the suspension rail comprise bevelledlips corresponding suspension element 29 in side view; it can be inserted through the opening between the lips and after a quarter turn can rest on the bevelledlips - Figure 4 shows another embodiment, in which the
separate part 4 of the conducting rail can be arranged with the opening upwards. Theupper edge 21 prevents that the moment which is caused by the lighting device, pulls the separate part loose. The suspension rail can be executed according to figure 1 or according to figure 2 as desired. Figure 5 shows the suspension and the conductingrail 3, the conductingstrip 6 and the current insulatingprofile 7 in perspective, as is shown in cross section in figure 1. - Figure 6 shows the embodiment according to figure 3 in perspective.
- Figure 7 shows the
lighting device 25 with thecontact part 26 and alamp part 27. Thecontact part 26 comprises the clampingplate 8, thespherical portion 9, the insulatingportion 10 and the threadedportion 11. Thelamp part 27 is executed in a known manner. - Figure 8 shows a possible dimensioning for the
separate portion 4 of the live conducting rail. This portion is substantially U-shaped in cross section. The outer dimensions thereof are a length a = 18,5 mm and a width b = 16,5 mm. Along the opening of the U, two cheeks are arranged which face each other, defining an opening width c = 9 mm. The cheeks have inwardly directed lips, which have a height d = 1 mm. - Figure 9 shows that the clamping
plate 8 has a length e = 12 mm and a width f = 8,5 ± 0,1 mm. A hole with screw thread g = M6 is arranged in the middle. The clamping plate has a rounding with radius r = 5 mm on two opposite corners. - It is easy to move a suspension element such as a
suspension element 28 over the raisededge 15, such as in figure 1, or asuspension element 29 between the slantinglips lighting device 25 can be moved with the help of thecontact part 26 in the live conducting rail by screwing thescrew thread portion 11 slightly out of theclamping plate 8, sliding thecontact part 26 in the conducting rail, and then screwing the screw thread portion tight again, as a result of which the clamping plate will rest on thelips 24 of the conducting rail, and thespherical portion 9 will be pushed against the conductingstrip 6. - Arranging a lighting device in the conducting rail is easy, in that the clamping
plate 8 is narrower than the opening in the conducting rail. The clamping plate can thus be inserted through the opening of the conducting rail, and after a rotation through 90° can rest against the lips of the conducting rail. - Figure 10 shows further embodiment of the suspension device according to the invention, indicated by 101, which is screwed with screws to the
wall 102. Just as the suspension device according to figure 1, thesuspension device 101 comprises alower leg 109 with a raisededge 110 for thesuspension element 28, ahorizontal tongue 106 with abeaded edge 107, and in addition ahorizontal ledge 105 and anupper leg 140 with a downward directededge 121 with an inward directedlip 122 for receiving a separatelive conducting rail 104. Thelive conducting rail 104 is shown separately in figure 11A and is substantially U-shaped in cross section, havingcheeks 115 facing each other along its opening, each of which has an inwardly directedlip 116. Thelegs 118 of the live conducting rail both have on their inner side alongitudinal cam 117 for receiving and securing an insulatingstrip 111, which is also substantially U-shaped and has inwardly directedcams 112 along its edges, so as to secure aconducting strip 113, which is also substantially U-shaped in cross section and has roundededges 114. This can be seen clearly in figure 12. - The conducting rail is constructed to receive a lighting device, the connecting
end 129 of which is shown in figure 10. Thesupport pipe 30 and thelamp part 27 can be executed in accordance with figure 7. The connectingend 129 of the lighting device has agrip 131 which can be attached, for example, by soldering to clampingplate 132. The grip and the clamping plate can also be made out of one piece. The grip can be slid over thesupport pipe 30. Acontact part 133 is secured to thesupport pipe 30 with the help of an insulatingportion 134 and can supply current to the lamp part by way of athread 136. In the grip 131 acompression spring 135 is partly accommodated, which rests against the insulatingportion 134. - In figure 10 it can also be seen that the suspension device can include a
front panel 108 which is attached on the lowest cheek to the conductingrail 104. - Figure 11 shows the
suspension device 103 which forms a whole, without the conductingrail 104. - Figure 12 shows another embodiment of the
suspension device 103 in which the conductingrail 104 is placed with its open side upwards. In this embodiment thefront panel 145 is bent downward to the back, and this front panel has an inwardly directedtongue 146 with beaded edge 147. - Figure 12A shows an embodiment which is similar to the embodiment of figure 12, but which has a
front panel 144 and atongue 106 with beadededge 107, which are taken from the embodiment of figure 10. In figure 12A the shortupper leg 140 with a downwardly projectinglip 141 can be clearly seen, behind which the live conductingrail 104 has to hook. For a better atachment a wedge-shapedslot 143 is arranged in themiddle leg 142, in which a wedge-shapedcam 120 on thebase 119 of the live conducting rail 104 (vide figure 11A) has to snap. Such a slot is also arranged in the rear wall of the suspension and conductingrail 103 of the embodiment of the suspension device according to figure 10, vide figure 11. - Figures 13 and 13A show the substantially
rectangular clamping plate 132 which is provided in the middle with ahole 150 for said attachment to thegrip 131 and which is provided withslots 151 along its short edges for cooperation with thelips 116 on thecheeks 115 of the live conductingrail 104. The clampingplate 132 has opposite roundedcorners 152 with a radius from the middle of thehole 150, which is, at most, equal to half the length of the clamping plate. - Fig. 14 shows a cross section of covering 115 provided with snap means 156, with which the suspension device according to figure 10 can be covered on places where no lighting device or suspension element is present, by snapping the snap means 156 in the opening of the conducting
rail 104. - Fig 14A shows a
corresponding covering 157 for a suspension device with a front panel which extends downwards to the rear. - Figure 15 shows a partial cross section of the live conducting
rail 104 in which twotransformer connections coupling blocks holes 162 or 162' in longitudinal direction for receivingpower cables 159, 159'. One of theholes 162, 162' is for the power cable to the transformer; a power cable in the other hole can lead the current to a coupling block of another conducting rail. Each power cable should be clamped with the help of two terminal screws throughscrew holes 163 or 163'.Transformer connection 160 has acurrent transferring plate 164 which has to be placed against the legs of theU-shaped conducting strip 113, andtransformer connection 165 has acurrent transferring plate 167 which has to be placed against the lips on the cheeks of the conductingrail 104. Between these an insulatingplate 168 of, for example, Pertinax is arranged. In thecurrent transferring plate 167 screw holes are arranged through whichset screws 169 should be screwed for pushing the current transferring plates against the conductingstrip 113 and the lips of the conducting rail, respectively. Thetransformer connections rail 104, if the conductingstrip 113 and the insulating strip have be removed there. - Figure 15A shows a cross section of the live conducting rail at the location of the
current transferring plates rail 104 in which the transformer connections are accommodated. - Figure 16 show a ceiling rail for placing
ceiling plates 171 of a system ceiling, theceiling strip 170 having twoedges 172 projecting to both sides, on which theceiling plates 171 rest. Theceiling strip 170 has in its upper portion a syntheticinsulating strip 173 provided withholes 174 to suspend the ceiling strip by hooking. The longitudinal body of theceiling strip 170 has a receiving space in the shape of a reversed U, withcheeks 175 facing each other along the opening of the U andcams 176 facing each other halfway along the height of the U. Just as in the suspension device according to the figures 10 and 12 in the live conductingrail 104, an insulatingstrip 111 and a conductingstrip 113 can be arranged in the U-shaped receiving space, which are secured by thecams 176. However, it is also possible to arrange a suspension element for an object to be suspended in the receiving space which can then rest on thecheeks 175. A covering can be snapped in the receiving space, analogous to thecoverings - The figures 17 and 17A show another embodiment of the
suspension device 203 and live conductingrail 204. Just as the conductingrail 104 of figure 11A, the conductingrail 204 is U-shaped in cross section, withbase 219,legs 218,cheeks 215,lips 216 andcams 217. However in this case, the upper leg has a wedge-shapedcam 220 on its outer side. Just as the suspension device of figure 11, thesuspension device 203 has alower leg 209 with raisededges 210. The suspension device further has anupper wall 206 and amiddle wall 205, onto which afront panel 208 is attached. On the inwardly directed side of the upper wall 206 a wedge-shapedrecess 221 is arranged, which corresponds to the wedge-shapedcam 220 on the conductingrail 204. The conductingrail 204 can now easily be attached in the suspension rail by sliding the rail between thewalls cam 220 then "snaps" into therecess 221. When sliding, the upper leg and wall will have to move apart slightly, which can be realized by a correct dimensioning of cam, leg and wall, so that the upper leg and/or wall is sufficiently flexible. - Figure 17 also shows that on the rear wall of the
suspension device 203 twoledges 207 are arranged. Together with the rear wall of thesuspension device 203 and thebase 219 of the conductingrail 204 theledges 207 form a cable cavity, through which, for example a power cable for other purposes can be lead. Because a tongue such astongue 106 is not present in figure 10 the suspension device is not so high. - Figure 12 also shows that in the suspension rail of a suspension device with a front panel which extends downward to the rear, a paper clamp can be arranged which has the shape of a
roll 180 which is annular in cross section behind which paper and the like can be slid and clamped. - The roll can also be polygonal.
- With the device described in the figures 10 to 13A the lighting device can easily be placed in the conducting rail. By grasping the connecting
end 129 by thegrip 131, the clampingplate 132 can be rotated such that the clampingplate 132 can be inserted between thecheeks 115 of the live conductingrail 104. Thecontact part 133 abuts against the conductingstrip 113, and when thegrip 131 is pushed further thecompression spring 135 is pushed in. The clampingplate 132 can be pushed in so far that it is located beyond thelips 116 on thecheeks 115 of the live conductingrail 104, and then thegrip 131 with the clampingplate 132 can be rotated a quarter of a turn. When releasing thegrip 131 thecompression spring 135 pushes the grip to the outside, and theclamping plate 132 is pushed against thelips 116 of the live conducting rail. On account of theclamping plate 132 havingslots 151 which correspond to thelips 116, thelips 116 will fall into theslots 151, as a result of which theclamping plate 132 is locked against undesired rotation of thegrip 131, so that as a consequence the lighting device will not come off the suspension device by accident. - The distance between the legs of the U of the conducting strip correspond to the diameter of the
contact part 133 of the lighting device. Due to this thecontact part 133 will not be able to slide transversely to the conducting strip so that thecontact part 129 will not tilt downwards and the lighting device will not come into accidental contact with the object exposed to view, as a result of the tilting. - The conducting rail is now suited for supplying a low voltage current, for example 12 Volt, to the lighting device, for example, a halogen lamp. The current is then supplied by the conducting strip and passes through the contact part and a wire in the lighting device to the lamp. The current is discharged through the outside of the lighting device and passes through the clamping plate by way of the clean scraped lips to the outside of the separate conducting rail for closing the circuit.
- Figures 1, 2, 3, 3A and 10 show a
suspension element thread element 33 with a thickening at its upper end projects. Because of this the suspension element can take the weight of an object to be exposed to view, without it being necessary to use a screw for clamping thethread element 33 in the suspension block. The thickening is clamped somewhat in the suspension block so that when lifting up the thread element the suspension block will also be lifted up, which simplifies the moving of the suspension element in the suspension device or the removal of the suspension element from the suspension device. - The thickening of the
thread element 33 can be formed together with the thread element and be cylindrical or have the shape of a reversed cone; other forms are also possible. The widening of the hole in the suspension block should also have a corresponding shape. The thread element can be a wire or a rod. - It is also possible to form the thickening separately by inserting a flexible thread element through the hole and then through a sleeve, bending the end and reinserting it in the sleeve, and then pinching the sleeve. The loop which projects above the sleeve can then be removed, and the sleeve be accommodated in the widening of the hole in the suspension block.
- With a suspension element constructed in this way it is achieved that the suspension block rests directly on the suspension rail, and that few means are needed to achieve this.
