Definitions

  • the invention concerns systems of spatial lighting. Ever wider use is now being made of lighting systems in which the sources of light can be turned in various di- rections. This possibility is especially popular for lighting homes and shop windows since it lends itself to creating and easily varying particular effects and play of lights.
  • lamps are usually placed using a var- iety of orientable supports enabling the beams of light to be directed according to preference.
  • Such types of supports however are limited in their movements and do not allow lamps to be placed, moved and oriented conveniently in a wide range of directions.
  • the electrical connections of these lamps are often made by means of conducting wires which may create great problems due to wires being broken or twisted when the orientable supports are moved.
  • Subject of the invention is a system of spatial illumina ⁇ tion comprising at least one hollow translatable body placed in a guide bar with inner longitudinal channels. Rods of conducting material are lodged in said longitudi- nal channels. Inside said translatable body, the form of which is complemen ary to that of the guide bar, are el ⁇ ectric contacts.
  • the translatable body supports a stem that can rotate free ⁇ ly in relation to said translatable body.
  • the stem is electrically connected to said electric con ⁇ tacts.
  • the stem supports an electric lamp connected el ⁇ ectrically to said stem, with possibility of rotating free ⁇ ly on the plane whereon lies the stem's axis of rotation. Therefore, determining translation of the translatable body, determining rotation of the stem and determining the angle of the lamp in relation to the stem, said lamp can be placed and oriented in space.
  • Advan ageously said stem is a hollow cylindrical stem made of conductive material. At one end it has a head from which the stem is electrically insulated by a plastic collar.
  • Said translatable body has a cylindrical collar whose in ⁇ ternal diameter is slightly greater than the stem's outer diameter.
  • said head is electrically connected to an elec- trie wire inserted in said hollow cylindrical stem.
  • said cylindrical collar of the translatable body is threaded on the outside.
  • a threaded bushing is inserted on the cylindrical stem to fix it to said cylin ⁇ drical collar.
  • said lamp comprises a joint the axis of which is substantially orthogonal to its own axis.
  • the ste.m comprises a joint whose axis is substan ially orthogonal to its own. Said joints, those of the lamp and of the stem, can turn inside the cylin- drical seats at the ends of two parallel and oppositely placed crosspieces.
  • Said crosspieces are spaced by an cylindrical spacer inserted on a central threaded pin with a key that penetrates through two threaded holes made in said two crosspieces respectively.
  • the lamp can therefore rotate freely on the plane whereon lies the stem's axis of rotation.
  • the strength of the hold exerted by the crosspieces' cylindri ⁇ cal seats on the cylindrical joints of the lamp and of the stem can be varied. Consequently the resistance opposed by the lamp to said rotation can also be varied.
  • translatable body In the translatable body there is a seat for a control ⁇ ling cylindrical body. On this body there are two pairs of diametrally placed tabs, each pair at a different level. The level of one pair of tabs corresponds to that of the longitudinal windows.
  • Thickness of said tabs is less than the width of said windows.
  • the level of the second pair of tabs corresponds to that of the extensions of the electric contacts.
  • the first pair of tabs will emerge from the win ⁇ dows in the walls of the hollow translatable body and they will fit into the guide bar's two longitudinal channels while at the same time the electric contacts will diverge and their end tabs will emerge from the apertures referred to above, also made in said walls. Since the position of said apertures corresponds to that of the guide bar's con ⁇ ductor rods, locking of the translatable body to said guide bar and electric connection of the electric contacts with the conductor rods will be assured.
  • a diametral cut is made in the head of said controlling cylindrical body emerging from the translatable body so that it can be turned with a screwdriver.
  • the above-mentioned guide bar is of metal and has a 'C'-shaped cross section throughout.
  • the invention clearly offers many advantages.
  • the lamp In relation to the guide bar, the lamp possesses a degree of freedom of movement that enables the beam to be orien ⁇ ted in virtually any direction, as well as being conven- iently moveable in every area of its space because of the way it can slide along the axis of said guide. This is a highly appreciated feature because it means that the light can be moved close to or away from some particular objec ⁇ tive so that special effects and a play of lights can be achieved .
  • translatable body's electric contacts are mobile. By simply rotating the translatable body's cylindrical body it in fact becomes possible to cut out electric connection with the guide bar during translation of the translatable body.
  • Fig. 1 Perspective view of the module,with lamp,of the lighting system with supporting translatable body on a length of the guide bar, with device for lock ⁇ ing and electric connection, and device for spatial orientation.
  • Fig. 2 Perspective view of the translatable body in its translating position.
  • FIG. 3. The same as above, in perspective, with the lamp lit.

  • Fig. 5. Perspective view of the device for spatial orienta- tion .
  • Fig. 6. Diagram to show function of the device for locking and electric connection, in the translating position.
  • Fig. 7. The same as above in the position with lighted lamp.
  • the system of illumination comprises guides 50 for transla- tion, support and electric connection formed of hexagonal metal bars 65 for one or more lamps 10, with support I I, by a device 55 for spatial orientation.
  • Cross section of said bars 65 is C-shaped throughout with longitudinal channels 51 opposite one another for insulating strips 63, 64 carrying copper rods 61, 62, one opposite the other .
  • Said translating body 23 is made from two substantially equal shells 21 and 22, comprising the cylindrical seat 31 and 32 with threaded edge for screwing on a locking ring 48 in order to fix the device 55 for spatial orientation.
  • Said body also comprises the semi-cylindrical seats 36 and 37 to form a slot for the locking and connecting part 35.
  • Said shells 21 and 22 carry the opposing flat and elastic contacts 27 and 28 fixed to tabs 33 and 34 projecting from the inner walls of said shells.
  • Said contacts 27 and 28 pass through, at one end, the ca ⁇ vity corresponding to the position of the cylindrical seat 31, 32, reciprocally offset, while at the other end said contacts extend, their extensions 45 and 46 passing across the cylindrical space bounded by the semi-cylindrical seats 36 and 37 and terminating in the ends 29 bent at approxi ⁇ mately 90° (Figs. 6 and 7)at the position of the opposing apertures 71 on the side walls of said shells 21, 22.
  • the body of the locking and connecting part 35 is cylin ⁇ drical is shape with a head 47 that comprises a pair of diametral transversal tabs 43 and 44 and a pair of diame ⁇ tral teeth 38, 39 on a level different from that of the first pair .
  • the shells 21, 22 are made to match up gui ⁇ ded by the tab 25 on one shell which penetrates into an eyehole 26 on the other.
  • the locking and connecting part 35 is lodged in the cy- lindrical seat created by the two semi-cylindrical parts
  • transversal tabs 43, 44 will lie at the level of the cleft 72 made in the walls of said shells 21, 22 while the longitudinal teeth 38, 39 will be at the level of the extensions 45, 46 of contacts 27, 28.
  • Stem 60 has a terminal swelling 41 and a head 42 elec ⁇ trically insulated from said stem by the ring 66 of insulating material. Said head is connected to the lamp 10 by the wire 67.
  • the end of the stem 60 fits inside the cylindrical seat 31 and 32 bringing the head 42 to contact 27 and the swel ⁇ ling 41 to the offset contact 28. Electrical continuity is thus assured.
  • the axial position of said stem is secured by the lock ⁇ ing ring 48 which screws into the cylindrical seat 31,32. After passing through the stem 60, the wire 67 enters the stem 68 of the lamp.
  • the spatial orientation device 55 comprises the cylin- drical joints 17 and 18 respectively turning inside slots 58 made in the ends of crosspieces 12 and 13.
  • Rotation of the lever 56 can lock said joints 17, 18 partly thanks to the friction washers 16, thus making the lamp 10 stable in practically any spatial position since the stem 60 freely makes axial turns in the slot created by the translatable body 23 and since the joints 17, 18 allow of a double angular position, round the parallel axes XX and YY, on the geometrical plane pas ⁇ sing through the axis of said stem 60.
