DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the invention shown in FIGS. 1-3 comprises an optical device stand assembly, generally designated 10, including an elongated rail member or beam 11, at least two (2) outrigger or leg support members 12 and 14 transversely and removably fixed to rail member 11, and a plurality of leg members 13 and 15 each mounted to an angled planar surface located at distal end sections of each leg support member 12 and 14.
As is evident in the drawings, rail member 11 includes undercut grooves 21, 22, and 23 each having an inner surface and extending parallel to the longitudinal axis of rail member 11. Groove 23 slidably carries an optical device support bracket, generally designated 30, along the groove length, and groove 22, on another side of assembly 10, carries outrigger or leg support members 12 and 14 with attached leg members 13 and 15. Outrigger members 12 and 14 are longitudinally laterally spaced along rail member 11 when it is horizontally disposed on a device supporting surface. Each leg member 13 and 15 includes an outer free end thereof defining an assembly footprint when stand assembly 10 is disposed in a free-standing position. Stand assembly 10 is effective to support an optical device, such as a film camera, a digital camera, or a video camera, above the assembly footprint and to suspend its objective lens over one of the opposite edge portions of rail member 11. Stand assembly 10 may also be used to support a lighting device, magnifiers, and/or an observation scope or some combination thereof.
More particularly, adjusting knobs 17 and 19 include threaded projections that threadingly engage slide members or nuts 19a shaped to slidingly fit into undercut groove 22 (FIG. 3), and to removably fix two (2) outrigger or leg support members 12 and 14 each having a respective single transverse center slot 12a and 14a that receives one side of rail member 11. Leg members 13 and 15 threadingly engage threaded projections (not shown) located on the angled planar surfaces of distal end sections of respective outrigger members 12 and 14.
Undercut groove 23 slidably carries optical device support bracket, generally designated 30, along the groove length on a side of assembly 10 perpendicular to the side bearing leg members 13 and 15. Angle iron bracket 30 has leg section 27 that supports universal pivot mount, generally designated 28, and leg section 35 that removably supports a tightening mechanism comprising slide member 32 and rotatable knob 31. Slide member 32 is shaped to fit into and be maintained in undercut groove 23 for sliding movement along the groove length. Threaded bolt 27a releasably fixes pivot mount 28 to leg section 27 for connecting an optical device to rail member 11, and threaded screws or bolts 35a removably fix slide member 32 to leg section 35. Pivot mount 28 coupled to bracket 30 includes threaded projection 29 that engages a camera or any other optical device to removably fix it on mount 28 and outwardly from the assembly support surface and may suspend the objective lens of a camera over one of the opposite edge portions of rail member 11. Rotatable knob 31 is fixed to a threaded projection that threadingly engages a delimited section of slide member 32 so that upon rotation, knob 31 draws the delimited section of slide member 32 against the inner surface of undercut groove 23 to releasably fix bracket 30 at a selected position along rail member 11. (Details of slide members 32 and 32a conform to the structure of slide member 48, 48a in the embodiment shown in FIGS. 8 and 9). Slide members 32 and 32a may be composed of fiberglass or any other resinous-like material.
FIGS. 4-6 show another embodiment of my optical device stand assembly, generally designated 10a, including outrigger members 24a and 26a having three (3) transverse slots 24b and 26b that have bores 24c and 26c (FIG. 5) and engage and receive one side of elongated rail member 11a that may be selectively disposed in any one of a multiple positions—at the transverse centerline across the longitudinal axis of leg support members 24a and 26a, or forwardly and rearwardly of the leg support transverse centerline. The structural configuration of outrigger or leg support members 24a and 26a of FIGS. 4-6 thus differ from leg support members 12 and 14 of FIGS. 1-3. Nevertheless, each pair of outrigger or leg support members 12 and 14, and 24a and 26a is identical in structural configuration with respect to each other and therefore interchangeable and universal in use. Elongated rail member 11a, leg members 13a and 15a, optical device support bracket 30a and undercut grooves 21a (FIG. 5) and 23a (FIG. 4), are identical in structure to corresponding elements of the embodiment of FIGS. 1-3. As is evident in the drawings, bracket 30a has a first leg section 27b that removably supports a universal pivot mount, as shown, and in a manner as described with respect to the embodiment of FIG. 3. Bracket 30a also includes leg section 35b that removably supports a tightening mechanism comprising a sectioned slide member 32a and a rotatable knob 31a that operates to tighten the sectioned slide member 32a to bracket 30a in the manner described with respect to the sectioned slide member 48, 48a shown in FIGS. 7-9. Threaded screws or bolts 35c removably fix end sections of slide member 32a to leg section 35b. When rail member 11a is normal to the device supporting surface, as shown in FIG. 5, outriggers 24a and 26a are slidably and fixedly disposed in grooves 21a and 23a located on opposite sides of rail member 11a that extends vertically.
In this specific embodiment, outrigger or leg support members 24a and 26a are about nine (9) inches long with three (3) slots—one (1) at the transverse centerline and each of two (2) laterally spaced about 11⁄2 inches on either side of the center slot—so as to make outriggers 24a and 26a universal in their use. As shown in FIG. 6, outrigger or leg support member 24a includes leg members 13a threadingly connected to angled planar surfaces at the outrigger distal ends. Adjusting knob 17a has a fixed threaded projection that extends through a bore into a center slot to threadingly engage a slide member or nut 17b shaped to fit into and be maintained in an undercut groove.
Outrigger members 24a and 26a may have more transverse slots depending on the number of extra rail members required for supporting lights, or moving rail members back and forth with respect to the transverse centerline of the outrigger members. Telescoping leg members may be used and moved in or out making the assembly short or tall and the footprint smaller or larger.
FIGS. 7 and 10-11 detail the structural configuration of the tightening means used to releasably fit leg support members 44 and 46 on rail member 42 having an end cap 42a at each end thereof. Each slide member 51 (FIGS. 10 and 11) that slidably fits into an undercut groove of rail member 42, shown with end cap 42a removed, is fixed to a threaded projection 50 that extends through bores 44b and 46b disposed within transverse slots 44a and 46a of respective leg support members 44 and 46. As is evident in the drawings, knob members 49 and 49a have threaded projections 50 that threadingly engage threaded bores in slide members 51, as shown in FIG. 11, to tighten slide members 51 against the inner surface of an undercut groove to releasably fix leg support members 44 and 46 to rail member 42 as shown in FIG. 10. Rail member 42 is one inch square and has a length of about 18 inches and each leg support member has a length of about 9 inches so that when each slide member 51 is loosened, leg support members 44 and 46 may be stored in a direction parallel to rail member 42 and tightened to be in releasably fixed alignment with the length of rail member 42. As shown, each leg member 44c and 46c has a delimited length sufficient to maintain rail member 42 from about 2 inches to about 3 inches above the assembly supporting surface. When leg support members 44 and 46 are folded in alignment with rail member 42, the resultant folded combination may then be placed in a bag made of flexible material for transport and storage.
The optical device support mechanism, generally designated 43, shown in FIGS. 7-9 includes means for connecting a pivotal optical device mount (not shown) to a threaded bore in a first leg section of an angle iron bracket 43. Threaded screws 45a fix slide member end segments 48 to second leg section 45 of the angle iron bracket. Slide member 48 (FIGS. 8 and 9) includes movable, shaped tightening segment 48a having a delimited length and threaded bore 48b that threadingly engages a threaded projection (not shown) fixed at one end thereof to knob 47 and extends through a bore (not shown) located in leg section 45 of the angle iron bracket 43 as shown in the drawings. Thus, by rotating knob 47, its threaded projection threadingly engages and draws slide member segment 48a against an inner surface of groove 41a to releasably fix the angle iron bracket to rail member 42. FIG. 9 shows (with the end cap removed from rail member 42) how shaped slide member 48 with tightening segment 48a may fit into undercut groove 41a. A graduated ruler 42b disposed along the length of rail member 42 enables accurate camera placement.
Depending on the assembly footprint desired, different types and length of rail members can be used to customize the footprint to the subject being examined or photographed. For example, four (4) foot or 16 foot long rail members may be used or shorter assemblies may be coupled end-to-end to extend the footprint length. The same outriggers or leg support members are usable because rail member outer dimensions remain the same. Rail members may be used that have different cross-sectional shapes such as a three-sided cross-section instead of a four-sided cross-section. Alternatively, a rail member that is about one inch thick and about three-and-a-half inches wide may be used to satisfy those who wish to work with heavier duty stock.
The assembly of the invention may be used for taking some special type pictures that may involve putting the subject in the middle of the footprint. A 3D image may be produced by taking a picture, looking at the field of view, moving the camera over to overlap the field by 60%, and taking another exposure. So the movable camera support bracket actually allows the making of stereo pictures without having a stereo camera. Setting the rail member away from the center of the outrigger, moves the camera back to change its location of the focus within the footprint so as to avoid showing the leg members in the photo. Multiple slots in the outriggers allow other beams to be placed across the outriggers to make the assembly even more sturdy.
The rugged, classic design and smooth operation of its structural configuration make versatile the use of the optical device stand assembly that is adaptable to many situations. The stand assembly of the invention is usable in the field of forensics for providing photographic evidence to record scientific data, crime scene investigation findings, documents, ballistics, tool marks, genealogy, field and laboratory application results, conducting autopsies, and three-dimensional imaging.
While the optical device support assembly has been shown and described in detail, it is obvious that this invention is not to be considered as limited to the exact form disclosed, and that changes in detail and construction may be made therein within the scope of the invention without departing from the spirit thereof.
