Description
- THIS INVENTION relates to a track for a dolly used in filming. It more particularly relates to a rail for forming a track for a dolly, and to a track for a dolly, the track including such rail. The invention relates also to a kit for forming a track for a dolly.
- The invention is to be used in the context of location or studio dollies, either with or without cranes or arms mounted thereon, used in filming. Accordingly, the term “dolly” as used herein should be understood to incorporate dollies or other wheeled platforms or structures on which arms or cranes for holding cameras are mounted or located.
- In accordance with one aspect of the invention, broadly, there is provided a rail for forming a track for a dolly, the rail being in the form of an extrusion having a roughly triangular profile when seen in end view, and including a base or foot, defined at the base of the triangle, and a crown defined at the apex of the triangle for engagement by a wheel of a dolly.
- More particularly, in accordance with this aspect of the invention, there is provided a rail for forming a track for a dolly, the rail including
- a roughly flat base or foot;
- a crown located operatively above the base for engagement by a wheel of a dolly; and
- two connecting webs fast with and connecting the base and the crown together, the webs converging towards each other away from the base, so that the rail has a generally triangular profile when seen in end view.
- The crown and the two connecting webs may be integrally formed with one another, so that the rail is of one-piece construction. The rail may be in the form of an extrusion. The rail may be constructed of any one of a metal and a metal alloy.
- The rail may include a reinforcing formation located between the base, the crown and the two connecting webs. For example, the reinforcing formation may be located inside the triangle defined by the base, the crown and the two connecting webs.
- The reinforcing formation may include a hollow reinforcing member, e.g. in the form of a tube, fast with and extending longitudinally along the base of the rail, the hollow reinforcing member projecting operatively upwardly towards the crown from the base, and two reinforcing webs fast with and respectively extending, along the length of the rail, between the hollow reinforcing member and the respective connecting webs, the reinforcing webs being spaced between the base or the foot and the crown.
- The reinforcing member may be in the form of a tube. The tubular reinforcing member may have a circular cross-sectional profile, the reinforcing webs extending generally radially outwardly from the reinforcing tube towards the connecting webs. The reinforcing tube and the reinforcing webs may be integrally formed with the remainder of the rail.
- The base of the rail may be provided with a longitudinally extending flange or extension projecting laterally from one side thereof for permitting clamping of the rail to an elevation structure, e.g. a scaffolding structure.
- An operative part of the crown, being the part of the crown which is in use engaged by a wheel of a dolly, may have any one of a circular and part-circular cross-sectional profile.
- The rail may include at least one connector mounted thereon at or adjacent at least one of its ends, for connecting the rail in end-to-end fashion to another similar rail having a complimentary connector mounted thereon at or adjacent its associated end.
- The rail may have one connector mounted thereon at or adjacent one of its ends, and may have a said complimentary connector mounted thereon at or adjacent its other end.
- For example, the connector may be mounted on at least one of the connecting webs of the rail, being located on an outer face of the connecting web. If desired, the track may have two connectors mounted thereon at or adjacent each of its ends, the two connectors being mounted on the respective connecting webs.
- At least one connector may be in the form of a latch or keeper associated with and complimentary to such a latch, to permit easy and quick connecting together of two abutting rails, and to permit easy and quick release of two rails which are connected together.
- The rail may be linear or the rail may be curved.
- In accordance with another aspect of the invention, there is provided a track for a dolly, the track including
- at least two rails as hereinbefore described, located such that they are laterally spaced from and run parallel to each other; and
- a plurality of location formations interacting with the respective rails for resisting lateral movement of the rails.
- In one embodiment, the location formations may be generally in the form of a wedge or chock, being laterally wedged in between each rail and a support surface, e.g. the ground, on which the rail is located. The two rails of the track are thus not connected together, so that the track can easily and quickly be formed or collapsed. For the same reason, the width of the track, i.e. the distance between the rails, can easily be adjusted in accordance with the axle length of a dolly.
- The track may include a plurality of rails connected end-to-end. The rails may be connected together end-to-end by means of the connectors as hereinbefore described.
- In accordance with another embodiment of this aspect of the invention, there is provided a track for a dolly, the track including:
- at least two rails as hereinbefore described located such that they are laterally spaced from and run parallel to each other; and
- a plurality of location formations interacting with the respective rails for resisting lateral movement of the rails, the location formations being in the form of clamps or the like mounted on an elevation structure, e.g. a scaffolding structure, which elevates the track above a said support surface, each clamp or the like engaging or clamping the flange or lateral extension of the base of one of the rails, to keep the rail in position relative to the elevation structure.
- In this embodiment, the rails may be connected together end-to-end by means of the location formations mounted on the elevation structure.
- In accordance with a further aspect of the invention, there is provided a kit for forming a rail for a dolly, the kit including:
- a plurality of rails as hereinbefore described; and
- a plurality of location formations.
- The invention is now described, by way of non-limiting example, with reference to the accompanying diagrammatic drawings.
- In the drawings:
-
FIG. 1 shows, schematically an end view of a rail in accordance with the invention for forming a track, also in accordance with the invention, for dollies used in filming; -
FIG. 2 shows, schematically, a three-dimensional view of part of a track in accordance with the invention; -
FIG. 3 shows, schematically, a side view of a different part of the track shown inFIG. 2 ; -
FIG. 4 shows, schematically, an end view of one of the rails forming part of the track shown inFIGS. 2 and 3 ; and -
FIG. 5 shows another embodiment of a track in accordance with the invention. - With reference to the drawings, a rail in accordance with the invention is generally designated by
reference numeral 10. As will be described in more detail hereunder, in order to form a track 12 (FIGS. 2 and 3 ) in accordance with the invention for dollies used in filming, tworails 10 are located such that they are laterally spaced from and extend parallel to each other, without any interconnection therebetween. - The
rail 10 is in the form of a metal or metal alloy extrusion and can, not within limits, be manufactured in any desired length. Therails 10 shown in the accompanying drawings are all linear, but, if desired, they can be curved, to permit forming of atrack 12 which includes a turn or turns. Further, if desired, a plurality of therails 10 can be connected end-to-end, to form atrack 12 having a length exceeding the length of asingle rail 10. - The
rail 10, as can particularly be seen inFIGS. 1 and 4 , has a roughly triangular cross-sectional profile. In particular, therail 10 includes a roughly flat base orfoot 14, defining a base of the triangle, and a partly circular cross-sectional profiledcrown 16 spaced operatively above the base orfoot 14, thecrown 16 defining an apex of the triangle. The base orfoot 14 and thecrown 16 are connected together by means of two connectingwebs web 18 slants, from one edge of the base orfoot 14 towards thecrown 16. The other connectingweb 20 has a lower portion which projects normally upwardly from the base orfoot 14, and an upper portion which slants towards thecrown 16, said upper portion of the connectingweb 20 and the connectingweb 18 converging towards each other as they near thecrown 16. Therail 10 further includes a reinforcement formation located between the base orfoot 14, thecrown 16 and the two connectingwebs reinforcement tube 22 fast with the base orfoot 14 and extending longitudinally along the length of therail 10, and tworeinforcement webs reinforcement tube 22 and the respective connectingwebs tube 22 has a circular cross-sectional profile, and thereinforcement webs webs - A part of the base or foot 14 projects laterally past the aforementioned lower portion of the connecting
web 20 to form a flange orlateral extension 28 which extends longitudinally along the length of therail 10. The purpose of the flange orlateral extension 28 is described in further detail hereunder. By virtue of therail 10 being in the form of an extrusion, the various portions or parts thereof are integrally formed, so that therail 10 is of one-piece construction. - Referring now in particular to
FIGS. 2 and 3 , when forming atrack 12 in accordance with the invention, tworails 10 are, as briefly described hereinbefore, located alongside each other, such that they are laterally spaced from and extend parallel to each other. Once therails 10 are laid down on a surface, for example the ground, a plurality of location formations is used to resist lateral movement of therails 10. In this example, the location formations are in the form of wedges orchocks 30 which are wedged in between the bases orfeet 14 of therails 10 and the support surface. As can be seen inFIG. 2 , the wedges orchocks 30 are located on either side of therails 10. Thus, by using therails 10 in accordance with the invention, atrack 12 which has no sleepers or cross-connectors is formed, thereby permitting easy and quick forming and collapsing of thetrack 12. Further, by virtue of the particular construction of thetrack 12, the width of thetrack 12, i.e. the distance between the tworails 10, can easily and quickly be adjusted in accordance with the axle length of a dolly used in association therewith. - In order to form a
track 12 having a length greater than the length of therails 10, a plurality ofrails 10 are connected together end-to-end in a fashion shown inFIG. 3 . To connect two rails in end-to-end fashion as shown inFIG. 3 , therail 10 is provided with connectors, generally designated byreference numeral 32. In this example, the connectors 32 (shown in concept only—seeFIGS. 2 and 3 ) are in the form of adjustable draw-catch connectors generally available and manufactured by Southco™. Accordingly, the connectors are not described in great detail. Briefly, however, each connector includes aconnector portion 34 and an associatedkeeper 36. Eachrail 10 is, adjacent one end thereof, provided with twoconnector portions 34, and at or adjacent its other end with twokeepers 36. In particular, as can be seen inFIG. 3 , theconnectors 32 are respectively mounted on the connectingweb 18 and on the slanting upper portion of the connectingweb 20, being located on outer faces of the connectingwebs rail 10 being provided withneck portions 34 and the abutting end of theother rail 10 being provided withkeepers 36. As will be appreciated, theconnectors 32 permit fast and easy connecting and disconnecting of tworails 10. - Referring now to
FIG. 5 of the drawings, another embodiment of atrack 12 in accordance with the invention is generally designated byreference numeral 40. In this embodiment, thetrack 12 is formed over a ditch or a valley (not shown), such that therails 10 forming part thereof are located at an elevated position above the ground. To provide for such elevation, thetrack 40 includes a scaffolding structure (shown in concept only) generally designated byreference numeral 42. Thescaffolding structure 42, at its upper edge, is provided with clamps or other connecting formations, shown in concept only and designated byreference numeral 44, which engage and clamp the flanges orlateral extensions 28 of therails 10, to retain therails 10 in position. - The invention as described and illustrated thus provides a rail which can be used quickly and easily to form a track in accordance with the invention, which track has no interconnection between parallel rails forming part thereof. This, in turn, provides not only for quick and easy assembling and disassembling of the
track 12, but also provides for easy adjustment of the width of thetrack 12. Further, by virtue of thetrack 12 having no sleepers or cross-connectors, actors or other film set crew can easily move between therails 10 without the conventional interference by sleepers or cross-connectors.
