DETAILED DESCRIPTION

(13) The following description is of exemplary embodiments of the invention only, and is not intended to limit the scope, applicability or configuration of the invention. Rather, the following description is intended to provide a convenient illustration for implementing various embodiments of the invention. As will become apparent, various changes may be made in the function and arrangement of the elements described in these embodiments without departing from the scope of the invention as set forth herein. It should be appreciated that the description herein may be adapted to be employed with alternatively configured devices having different shapes, components, lights, brackets, support mechanisms and the like and still fall within the scope of the present invention. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation.

(14) Reference in the specification to one embodiment or an embodiment is intended to indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least an embodiment of the invention. The appearances of the phrase in one embodiment or an embodiment in various places in the specification are not necessarily all referring to the same embodiment.

(15) In the following description, certain terminology is used to describe certain features of one or more embodiments of the invention. For example, the term light or light strip as described herein may include, but is not necessarily limited to, LEDs strings and tube LEDs. The light panels housing the light strips may be constructed from a wide variety of materials including, but not necessarily limited to, aluminum, composites, plastic, carbon fiber and the like. The light panels may include any number of reflectors, diffusers, dimmers, remote controls, and the like. In some cases, the light strips comprise tube LEDs without the need for other diffusers or other protective light strip cover.

(16) In accordance with various aspects of the present invention, a collapsible tight tunnel is described for mobile on-site inspection of vehicle surface finishes. The present invention may be used to assess panel damage after a hail storm or for quality control after panel repairs are completed. The light tunnel may be used for any number of surface inspection purposes. That being said, the present invention is described herein in the exemplary context of an inspection tunnel for hail damage.

(17) The terms bracketry, hinges and pins, as used herein, include any hardware suitable to allow for or prevent relative movement of two adjacent panels as the case may be. Suitable hardware may be of any suitable material, shape or size.

(18) FIGS. 1-5 illustrate different views of a collapsible light tunnel 100. Collapsible light tunnel 100 according to one embodiment of the present invention includes first vertical light panel 102, second vertical light panel 104, first angled light panel 106, second angled light panel 108, first overhead light panel 110, and second overhead light panel 112. First and second light panels 102-112 include LED light strips 114 and diffusers 116. Adjacent first panels 102, 106 and 110 and adjacent second panels 104, 108, and 112 are collapsibly coupled by hinges 118 to be movable between a stowed position and a deployed position. Brackets 120 serve to maintain the panels in the deployed position.

(19) LED light strips 114 are electrically coupled to a power supply 122. LED light strips 114 may be configured and arranged similarly or differently within each panel. For example, LED light strips 114 may be vertically arranged within first and second vertical side panels 102 and 104 and may be horizontally arranged within first and second angled light panels 106 and 108. Any number of LED light strips 114 or other arrangements of LEDs may be used in any of panels 102-112.

(20) Hinges 118 may be configured as any manner of coupling or bracketry capable of allowing coupled panels to remain coupled during movement between the stowed position and the deployed position. Of course, in some embodiments, the panels are fully separable during transport, e.g., via separable panel connectors/hinges. The hinges are positioned on the inside of the tunnel between the vertical side panels 102, 104 and the angled (e.g., 45 degree) panels 106, 108 and between the angled panels 106, 108 and the top horizontal panels 110, 112. The hinges are positioned on the outside of tunnel between the top horizontal panels 110, 112. This allows the top horizontal panels 110, 112 and angled panels 106, 108 to fold inward relative to the tunnel profile into a stowed position alongside vertical side panels 102, 104.

(21) Positioning brackets 120 are placed across the top corners of vertical side panels 102, 104 and the adjacent bottom corners of angled panels 106, 108, an similarly across the top corners of the angled panels 106, 108 and the adjacent corners of horizontal panels 110, 112. Horizontal panels 110, 112 are connected by two straight brackets in the middle of the tunnel arch on one or both sides of the tunnel. A hole or aperture through each bracket 120 and through the structural edge of panels 102-112 receive a fastener, e.g., D-ring, to secure the panels together in the deployed position.

(22) In one embodiment, six individual panels 102-112 are hinged together to form the collapsible light tunnel (e.g., two vertical side panels, two angled panels, and two horizontal panels). Vertical side panels 102, 104 may be sized to be twice as long as the angled or horizontal panels 106-112, or to be at about as long as the combined respective angled and horizontal panels 106-112. For example, angled panels 106, 108 may be shorter than horizontal panels 110, 112, but the combined length of both may equal that of the respective vertical side panel 102, 104. This sizing allows the tunnel panels to fold into a stowed stack by folding the tunnel in on itself in the form of a letter M.

(23) Brackets 120 may be configured as any structure suitable to maintain adjacent panels in respective deployed positions during use of collapsible light tunnel 100. Brackets 120 may be secured to respective panels by removable fasteners such as bolts, pins, D-rings and the like.

(24) With reference to FIG. 6 collapsible light tunnel 100 may be collapsed into a stowed/stacked position for transport or storage. In the stowed position, first angled panel 106 and first overhead panel 110 may fold adjacent first vertical light panel 102 in a stacked arrangement. The stacked arrangement of first panels can be moveable separate from the corresponding stack of second panels 104, 108, 112. In some embodiments, the first and second stacks of first and second panels may remain coupled in the stowed position and may be transported as a full stack of light panels for a full light tunnel. In some embodiments, first and second vertical light panels 102, 104 include handles for lifting the first and second stacks. In some embodiments, the first and second vertical light panels 102, 104 include straps, latches or other structures for maintaining the first and second stacks in the stowed/stacked position during transport.

(25) FIGS. 7A-D shows the step-by-step assemblage of collapsible light tunnel 100 according to FIGS. 1-6. In FIG. 7A, tunnel 100 is depicted initially in a first stowed position. In FIGS. 7B-C First angled panel 106 and first overhead panel 110 are pivot away from first vertical panel 102 into an arched deployed position. Second panels 104, 108, 112 are similarly rearranged into an arched deployed position by bending of hinges 118 . . .

(26) Brackets 120 are secured to respective adjacent panels to maintain panels 102-112 in the deployed position. Brackets 120 may be secured by any suitable structural means, e.g., fasteners, snap-fit, sliding channels, and the like to prevent hinges 118 from collapsing until brackets 120 are removed or repositioned. Once light tunnel 100 has been fixed in the deployed position by brackets 120, it may be lifted into an upright position. In some embodiments, light tunnel 100 is sized to receive a portion of vehicle thereunder for visual inspection of the surface with the benefit of intense light from multiple angles.

(27) To collapse tunnel 100, the process is simply reversed, i.e., the tunnel is laid on its side, brackets 120 are removed, respective first and second panels are folded into a stack and respective first and second stacks, or the entire stack, are secured together for storage and transport.

(28) FIGS. 8-11 illustrate a collapsible light tunnel according to another embodiment. With reference to FIG. 8, collapsible light tunnel 200 includes a series of light panels 202-212, including pairs of vertical side light panels 202-204, angled light panels 206-208, and overhead light panels 210-212. Light panels 202-2012 each include a series of LED strips 214 positioned behind a diffuser 216. Diffuser 216 is supported, e.g., stretched between, frame members 222, which are secured at their ends by corner fixtures 220.

(29) Diffuser 216 may include fabric secured to frame members 222 by removable frame clips 218. Alternatively, diffuser 216 may comprise a semi-rigid fabric/material or even a rigid diffuser material. Additional panel rigidity is provided by crossmembers 228 extending diagonally between opposed corner fixtures 220. A central crossmember fixture 230 secures crossmembers 228 near their midpoints. Any number, combination or form of frame, stiffeners, clips, crossmembers may be used in any of panels 202-212. The diffuser panel may be a fabric panel stretched over a pipe frame with cross-bracing.

(30) Corner fixtures 220 include an attachment point 226 configured to secure two adjacent light panels together. Attachment points 226 may be configured at any angle to support adjacent light panels in a desired configuration, e.g., coplaner, angled, arched and the like. Attachment points 226 may be configured with a quick-release mechanism, e.g., with a snap-fit, friction-fit, lugged, threaded, or other suitable connection.

(31) LED strips 214 may be semi-rigid, rigid, or pliable light stings/strips configurable to achieve a desired lighting coverage and intensity adjacent the diffuser. LED strips 214 may be jointly wired within a panel, or across multiple panels, e.g., with electrical couplers/connectors 232 positioned between panels. In other embodiments, a central LED may be configured as a central point source provided behind a diffuser panel, e.g., collocated with the cross-member support fixture 230.

(32) Diffuser 216 may comprise an suitably translucent material, e.g., plastic, woven or non-woven fabrics, or films, and may include perforations, vents, or other passages, e.g., for passage of wind, light, wiring, and the like. Similarly, back panel 234 may be made from any suitable material to support and/or cover LED strips 214.

(33) In other embodiments, the tunnel may be formed as a curved arch that is separable or hinged at its apex. The arch may include an arcuate pipe frame and a fabric stretched over the pipe frame. The fabric panels may be stretched over the tunnel frame and may include any number of layers or coatings or other features such as air vents.

(34) The crossmembers may be retained by the crossmember fixture in the stowed position, e.g., with two halves of the crossmember fixture being rotationally coupled to allow the crossmembers to rotate into alignment for storage. The light panels, base, and crossmembers are stackable and stowable in a case/bag for convenient storage and transport. For example, the collapsible light tunnel panels, crossmembers and fixtures may be configured to fit within a case of about 343715 inches. When erected, the light tunnel can be set-up to provide a tunnel of about 111 inches wide, 88 inches tall, and 37 inches wide. In some embodiments, the angle of overhead panels may be adjusted to achieve a desired tunnel width and/or height. In some embodiments, the panels are fully separable. In some embodiments, some panels may remain hinged and folded when stowed. In some embodiments, LED electrical wiring may connect two separate panels when stowed.

(35) In some embodiments, joint fixtures are positioned between the corner fixtures of adjacent panels to retain the panels in a fixed position/geometry. For example, joint fixtures may comprise projections or recess to mate with complementary features of adjacent panels.

(36) A base may be used to provide additional stability and may include projections, recesses or other features to engage the lower light panels. The base may be foldable or otherwise compactable for ease of storage and transport.

(37) The collapsible, modular light tunnel may be configured of any desired geometry to facilitate inspection of vehicles on-site. For example, panels may be rectangular, arcuate, or curved. Similarly, the light tunnel may include castors or rails to facilitate movement of the tunnel relative to a vehicle. Any number accessories may be attached to the tunnel, e.g., a control panel, work station, tool rack, cameras, and the like.

(38) Accordingly, the present invention provides a collapsible mobile light tunnel for onsite inspection of damaged vehicles. The tunnel includes lightweight light panels collapsible coupled for movement between a stowed/stacked position and a deployed/erected position. Various alternative embodiments may include cameras for documenting damage, controls for changing the intensity, color or other quality of the light emitted from the light panels.

(39) Similarly, while the present invention has been described herein as a collapsible light tunnel, the present invention may be readily used with any number of other devices now known or hereafter developed. Finally, while the present invention has been described above with reference to various exemplary embodiments, many changes, combinations and modifications may be made to the exemplary embodiments without departing from the scope of the present invention. For example, the various components may be implemented in alternative ways. These alternatives can be suitably selected depending upon the particular application or in consideration of any number of factors associated with the operation of the device. In addition, the techniques described herein may be extended or modified for use with other types of devices. These and other changes or modifications are intended to be included within the scope of the present invention.
