  • a chandelier frame made from rings and spokes.
  • the rings are adapted for supporting ornaments, and the spokes are attached to the rings for supporting the rings, preferably coaxially.
  • the rings and spokes are attached to one another by interengaging locking means which mechanically and detachably secure the rings and spokes to one another.
  • the rings and spokes may be formed entirely from nonstressed metal, and most preferably are cut from flat sheet metal.
  • the rings and spokes are held together by interlocking tabs and slots, the tabs and slots being preformed and located at discrete positions to precisely align the rings and spokes with respect to one another.
  • the tabs include a head and a neck, the neck having a narrower diameter than the head.
  • the tabs may be located on a plurality of arm segments integral with and extending from a main segment of the spokes and defining platforms for seating the rings. In a most preferred embodiment, at least a portion of one of the slots and tabs is cut using a laser.

  • a chandelier frame is shown in a preferred embodiment in Fig. 3 which illustrates multiple aspects of the invention.
  • the depicted chandelier frame may be manufactured from flat, nonstres *sed sheet material without the use of welds, eyelets, screws or rivets to join any of the parts together.
  • the use of non-stressed parts, cut precisely, aligned and assembled without the use of bending, welds or other deforming processes, results in a superior product. High structural tolerances are possible that significantly enhance the optical effects obtainable with a chandelier built in this manner. This product is also easy to assemble.
  • FIG. 3 utilizes coaxial upper and lower rings, 30 and 32 respectively, disposed about and relative to a center piece 34 shown in phantom.
  • the rings are aligned and separated from each other by attachment to a set of spokes 36 radially positioned relative to the center piece 34.
  • the spokes 36 and rings 30, 32 of the embodiment depicted in Fig. 3 define a thickness 38 transverse to their flat surfaces 40.
  • the thickness 38 is substantially less than the width 42 of the flat -1- ⁇ urfaces.
  • each piece tends to define a plane, the rings defining parallel planes and the spokes defining planes substantially perpendicular to these parallel planes.
  • the plane of the spokes is generally oriented vertically in use, contributing to the strength of the frame. .. t
  • the edge of the spokes 36 transverse to the flat surfaces 40 and facing the rings 30, 32 define nonlinear segments 46, 48, 50 and 52 (i.e., the straight segments meet one another at angles). Two of these segments 46 and 50 define parallel platforms that support a flat side of the upper and lower rings 30, 32, respectively. These platforms, thus, make possible the integral combination of both spacing the rings 30, 32 axially along the center piece 34 and aligning the rings 30, 32 coaxially with respect to the center piece 34.
  • the platforms 46, 50 preferably include tabs 56 extending from the platform and engaging integrally formed through-cut slots 58 cut at predetermined locations in the rings 30, 32.
  • the tabs 56 and slots 58 allow for positive mechanical interengagement of the rings 30, 32 and the spokes 36.
  • the tabs 56 and slots 58 also precisely align the rings 30, 32 radially relative to one another and to the spokes 36. Through this interengagement, the rings then are secured in position against rotation about the center piece 34 and displacement radially relative to the center piece 34.
  • ornaments 60 depending from different rings (which ornaments are located through preformed holes 62 by means of hooks 64) maintain a precise alignment with respect to -one another for an enhanced optical effect.
  • the structure is "substantially nonstressed". Since the deformation occurs at only small isolated points upon the chandelier frame where radial alignment of the rings relative to each other and to the center axis is fixed, the structural tolerance of the chandelier frame remains extremely high (less than 3/64 inch radial and axial tolerance) . Additionally, the speed at which the tabs may be twisted allows for quick and simple assembly.
  • the details of a preferred tab are depicted in Fig. 6.
  • the tab is constructed from a generally rectangular projection 82 formed integrally with a spoke and extending from a platform 84 for supporting a ring (not shown).
  • the seat 92 of the tab is sized to fit snugly within the ring slot so as to precisely align the ring and spoke and to prevent any significant lateral movement of the ring with respect to the spoke.
  • the slots 90 on the tab are sized with respect to the ring such that they converge and form the neck 94 at a position within the ring slot when the ring is ⁇ eated on the platform.
  • the downwardly facing surfaces 98 of the head 96 likewise extend into the ring slot when the ring is seated on the platform. As such, when the tab head 96 is twisted, the downwardly facing surfaces 98 of the head 96 engage surfaces of the ring adjacent the slot and ensure a tight interlock between the ring and spoke. Motion in all degrees of freedom is prevented.
  • the tab slots 90 are straight. It should be understood, however, that other configurations, including slots defining a radius may be used, and may even be preferred.
  • the neck width 100 is 1.7 times the spoke thickness 102, and the distance 105 from a ⁇ idewall 88 to the neck is 1.25 the spoke thickness.
  • the head width 104 is at least 4.2 times the spoke thickness 102.
  • the sheet metal from which the spokes and rings were cut was a close-tolerance, cold-rolled, steel sheet, flat roll and full hard, 14 gage thickness (.074 inches, + .002 thickness tolerance), obtained from Lapha -Hickey, Chicago, IL, under the trade designation C-1010 alloy.
  • the neck width was about .125 inches, and the head width was about .3 inches.
  • Spokes may be constructed elaborately to support a multiplicity of coaxial, axially separated, rings.
  • One type of ⁇ poke utilizing the twisting tab concept is shown in Fig. 7(a).
  • the spokes depicted contain upward facing tabs 120 for mounting t'o a center unit. They have downwardly facing tabs for supporting ring ⁇ .
  • a tab ⁇ uch as tab 124 is located along a segment 125 of the spoke ⁇ uch that a large length 126 of segment 125 is disposed on either side of the tab 124.
  • Another tab 128 is in clo ⁇ e proximity to an end of segment 130, with a substantial length of segment 132 on one side of the tab 128 and with only a ⁇ hort length 134 on the other side, the ⁇ hort length being ⁇ ufficient in order to provide an adequate platform for the ring.
  • a ⁇ econd type of ⁇ poke depicted in Fig. 7(b), has supporting arms 138 extending from a main segment 140 and defining arm platforms 142 from which rings hang with their weight supported by the tabs.
  • the spokes of Fig. 7(b) may include a pair of tabs 146 disposed upon one of the arms 138 for attachment to a center unit. The use of two tabs helps to provide extra strength when attached to a center unit (which has two corresponding ⁇ lot ⁇ ).
  • a ⁇ poke al ⁇ o may be provided with a hole 154 di ⁇ posed at one end of the ⁇ poke. This hole may be used, for example, to join the ⁇ poke, by mean ⁇ of a fastener, to the hole of another spoke, such as hole 148 of the ⁇ poke 150 ⁇ hown in Fig. 7(a).
  • Elaborate rings may be formed to construct a chandelier frame according to thi ⁇ invention, particularly if laser cutting is utilized. Shapes varying from an ordinary annulus having a variety of holes, slots and edge contours are possible.
  • Fig. 8 depicts a series of six slotted rings 160, 162, 164, 166, 168 and 170, concentric about a central axis 170.
  • Each of these rings contains a series of small holes 174 for hanging ornaments from hooks, as well as certain large holes 176, as shown upon the outermost ring 160, through which ornaments such as crystal rods may be suspended.
  • Each of the rings contains, evenly spaced about its perimeter, a series of projections 178 having slots 179 cut therethrough at precise locations.
  • the slots 179 may accept the mechanically interengaging tabs described above.
  • the precise alignment of the slots 179 and ornament mounting holes 174, 176 between two or more rings in the assembled frame achieves ⁇ ymetrical cry ⁇ tal placement to a degree never before achieved.
  • Each of the ⁇ e rings may be spaced axially relative to the other rings by attachment to ⁇ pokes such as those shown in Figs. 7(a) and 7(b).
  • Certain rings 160, 162, 166 and 168 have slots di ⁇ po ⁇ ed in radial alignment (dotted line 180) relative to each other while other rings 164 and 170 are radially aligned (dotted line 182) offset to the other radially aligned ⁇ ot ⁇ . This allows certain ⁇ pokes to support some of the rings while other ⁇ poke ⁇ carry other rings, thus preventing overloading of ⁇ pokes and making possible very large groupings of axially spaced rings.
  • the elaborate ⁇ pokes and rings of Figs. 7(a), 7(b) and 8 may be combined to form an equally elaborate tab and slot type of chandelier shown generally in partial side view in Fig. 9.
