Definitions

  • This invention relates to an improved support for electrical devices connected to wiring such as lighting equipment of the kind used in the illumination of theatres, studios and other areas where special lighting effects are required.
  • the operation of theatres and studios necessitates the use of illumination often of high intensity and provided by light sources which have to be positioned in particular ways in order to enable certain desired lighting effects to be achieved.
  • These effects are normally obtained by the use of numerous lights which are attached to a support.
  • the latter usually takes the form of a frame the size and shape of which depends upon the dimensions of the area to be illuminated.
  • the simplest form of frame can consist of a single straight member which might extend horizontally above a stage. However depending upon circumstances a frame can have a more complex shape incorporating several arms extending in different directions.
  • the supports in current use are made in different ways.
  • one form comprises three cylindrical main members arranged in parallel as a triangle and secured together by struts.
  • the main members consist generally of metal tubes to which electric lights and other devices for example loudspeakers can be fixed by G clamps so that they can be pointed in any desired direction.
  • D1 discloses a plurality of hollow members connected together to form a supporting frame, electrical wiring being provided within the hollow members.
  • the members are not disposed parallel to each other and connected by struts to form a trussed load-bearing beam.
  • D2 disclosed a trussed load-bearing beam of three elongate elements connected by struts. None of the elements, however, is hollow and adapted to serve as trunking for electrical wiring.
  • D3 discloses a frame similar to that of D1 consisting of connected hollow members distributing electrical power.
  • D4 discloses a frame similar to those of D1 and D3, but like them, does not disclose three elongate members connected by struts to form a trussed supporting beam, one of the elongate members being hollow and constituting trunking.
  • An object of the invention is to provide an improved support for electrical devices.
  • the invention provides a support for electrical devices comprising three elongate members (2,3,4) at least one of which (2) is hollow, interconnected by struts (5) to form a frame, wherein: the three elongate members (2,3,4) are arranged, when the support is viewed in cross-section in a plane extending across the longitudinal axes of each of said elongate members, at the apices of triangle; said at least one hollow member (20) has an opening (6) extending lengthwise of said at least one elongate hollow member; and means are provided for securing electrical wiring within said at least one hollow member to enable said at least one hollow member (2) to function as electrical trunking for supported electrical devices.
  • the effect of this invention is that one or more of the elongate members is utilised as trunking for the wiring and in this way various advantages are obtainable.
  • the wiring of a support is achieved more quickly and with better aesthetic effects than hitherto.
  • the ends of the components of the support and cornerpieces can be adapted more easily so as to enable strong and complex supports to be assembled quickly from components which are less expensive and less numerous than those which are in current use.
  • the support shown generally as a frame (1) consists of three elongate members (2), (3) and (4) which can conveniently be referred to as trunking member (2) and main members (3 & 4) arranged in parallel in the form of a triangle.
  • the members can be constructed of any strong material for example aluminium or steel tubing which is secured together by struts (5) preferably by welded joints.
  • Trunking member (2) is in the form of a cylindrical box provided with an opening (6) extending lengthwise of the member and provided with a lid (7) which conveniently forms a push-fit with the side walls of member (2).
  • the lid can be fixed by other means for example nuts, bolts or screws.
  • a wall of trunking member (2) is provided with a series of apertures (8) to enable wiring from each individual applicance (not shown) attached to members (3 & 4) to enter the member (2).
  • the apertures of this series of apertures (8) can be supplemented or replaced by electrical connections for example surface or flush mounting sockets (66) to enable the wire of each individual appliance to be connected to wiring in the trunking member.
  • the support described above can constitute a component of a more complex support by attachment of extension pieces or angled components.
  • main members (3 & 4) and trunking member (2) are all provided with bolt holes (9).
  • a spigot (10) is then inserted into the end of each of main members (3 & 4) until holes (9) and (11) are in register thereby enabling a bolt to be inserted and the spigot and the member to be secured together.
  • trunking insert (12) having bolt holes (13 & 14).
  • the trunking insert is slid into the end of the trunking member (2) until holes are in register after which the insert and the trunking member can be bolted together.
  • Each of members (2, 3 and 4) have now extending from them half a spigot or trunking insert having spare bolt holes on to which straight or branched supports can be bolted.
  • the trunking member (2) consists of two hemispherical walls (2 & 7) which can be united by the methods described above.
  • the main members (3 & 4) consist of aluminium or steel having a circular cross section.
  • trunking member (2) can comprise a tube having a circular cross section and the wall of the tube is provided with a longitudinal aperture. Wiring can be secured within the trunking by the use of circular spring clips.
  • the opening in the wall of the trunking member can be either continuous or discontinuous.
  • the present supports are especially advantageous in the construction of complex structures. These can be made by first fixing the ends of two or more main members and a trunking member to a base plate to form an assembly and then securing the assembly to a connecting member.
  • a single connecting member may have several assemblies connected to it each incorporating a number of main members.
  • This aspect of the invention is illustrated in Figure 4 in which a connecting member (41) comprises a hollow metal sphere having two access holes (42) and a passage (50) in register with the trunking member (52).
  • An assembly of main members (43 & 44) and a trunking member (52) is formed by welding the ends of the members to base plate (45) which has an aperature (49) in register with the interior of member (52).
  • the plate (45) is then secured to connecting member (41) by bolts (not shown) which pass through bolt holes (46) in the base plate (45) and corresponding holes (47) in the connecting member.
  • Access holes (42) enable tools to be inserted into the member for the purpose of tightening the bolts.
  • the main members (43 and 44) and the trunking member (52) comprise tubes of rectangular cross section.
  • the trunking member is provided with a longitudinal opening (48) to permit the insertion of wiring which passes through hole (50) in the wall of the connecting member (41).
  • the wiring is secured within the trunking member by a push-on lid (not shown).
  • the ends of the members remote from the base plate (45) are provided with holes to enable the assembly to be connected to further lengths of main and trunking members to enable the completion of the final structure.
  • the main and trunking members are connected together by reinforcing struts (51) and are welded on to one face of the base plate, the reverse side of which is shaped to enable it to conform with the curved surface of the spherical connecting member.
  • FIG. 5 illustrates a part of a support in which the connecting member is a hollow cylinder (55) in which the open end (56) provides access to enable bolts (57) to be inserted through holes (58) in the cylinder into base plate (59).
  • the connecting member can have any regular shape. For example it can be hexagonal, square, triangular, oval etc.
  • Preferred connecting members are hollow although they can be mainly solid provided that they incorporate any cavities which may be required to enable bolts or other fixing means to be used to connect the connecting member to other members forming the support.
