The present invention relates to work area curtains and more particularly to work area vehicle flexible illuminating curtains.
Flexible work area or isolation curtains may be used to separate or divide one working area from another and to contain objects, tools, debris, dust, and other items in one or excluded from a self-contained working area. This may include various industrial and clean room work areas. Isolation curtains may be particularly useful in the automotive repair context to prevent cross contamination of materials. In particular, it may be advantageous to separate work areas designated for vehicle aluminum repair from those work areas designated for vehicle steel repair.
Dust, debris, and other particulates caused by welding, brazing, grinding, sanding, buffing, polishing, and other abrasive techniques may create hazy or dusty working conditions within the working area. As a result, the lighting conditions of these work areas may be compromised, even with proper ventilation and dust extraction systems. Poor lighting conditions can make service and repair tasks more difficult and can affect the quality of the repair.
In the past, lighting systems in working areas separated or enclosed by isolation curtains have been suspended from the ceiling or integrated with overhead truss systems. In some cases, the inner curtain walls of an isolation curtain may comprise a reflective surface such that the light from an overhead lighting system may reflect off of the curtain walls and better illuminate the working area. However, due to the haze, dust, and debris generated during a repair, the lighting conditions within a work station may be less than optimal, even with these reflective surface solutions. The sides of a vehicle and other areas not directly lit by the overhead lighting system may be particularly poorly lit, compromising optimal repair service conditions. Moreover, repair professionals, tools, and other objects may shade or block certain areas of the vehicle from the overhead lighting systems, which may also compromise repair conditions. For example, in work bays with service lifts, collision repair benches and work benches when vehicles are elevated thereon, they literally block out overhead lighting.
Thus, there is a need for a lighting system for work area isolation curtains that addresses these noted challenges.
In one embodiment, a work area illuminating isolation curtain having a length and a height comprises an illuminating source extending along the length of the curtain. The illuminating source may be positioned along the length such that when the illuminating source is illuminated, the emitted incident light rays shine generally perpendicular to the curtain or generally parallel with respect to a ground surface or floor of the work area. This may allow for the emitted light rays to better illuminate the front, rear, or side surfaces of an object enclosed by the isolation curtain.
In another embodiment, a work area illuminating isolation curtain having a length and a height comprises an illuminating source extending along the length of the curtain. The illuminating source may comprise LED strips housed within pockets extending generally parallel to the bottom edge of the curtain. A vertical pocket may house an LED strip as well and may connect the LED strips housed within the horizontal pockets with a power source and/or a controller. The illuminating source may be positioned along the length such that when the illuminating source is illuminated, the emitted incident light rays shine generally perpendicular to the curtain or generally parallel with respect to a ground or floor surface of the work area. This may allow for better illumination of the working area enclosed by the isolation curtain.
In yet another embodiment, a work area illuminating isolation curtain having a length and a height comprises an illuminating source extending along the length of the curtain. The illuminating source may comprise LED strips housed within pockets extending generally parallel to the bottom edge of the curtain. The LED strip may be in electrical connection with a power source and/or a controller. Sensors may be positioned along the pockets or elsewhere such that they may track motion in and conditions of the working area. The sensor inputs may be received by the controller and the individual LEDs disposed along the LED strips may be configured to adjust their elevation angles to better illuminate a particular section of an object being worked on within the working area.
In yet another embodiment a work area illuminating curtain having a length and height comprises illuminating sources extending along the length of both sides or opposed faces of the curtain. The illuminating sources may be positioned so that when illuminated the light rays extend generally perpendicular to their respective side of the curtain or generally parallel to a ground surface or floor of the adjacent work area. This may allow the emitted light rays to illuminate work areas on both sides of the curtain and the front, rear, side, or under surfaces of an object in the work area and elevated from or above the floor of the work area. The illuminating sources may comprise LED light strips received within pockets extending generally parallel to the bottom edge of the curtain or the floor.
Multiple embodiments of an illuminating isolation curtain 2 are described with reference to the drawings, wherein like numerals reference like structures. Although illuminating isolation curtain 2 may be illustrated and described herein as including particular components in a particular configuration, the components and configuration shown and described are provided for example purposes only. The figures and descriptions of the embodiments described herein are not intended to limit the breadth or the scope of the inventive concepts or the appended claims in any manner. Rather, the figures and detailed descriptions of illuminating isolation curtain 2 are provided to illustrate the inventive concepts to a person of ordinary skill in the art and to enable such person to make and use the inventive concepts.
Turning now to the drawings,
The curtain walls 4 may be coupled with a track 12 in a known manner, such as by hooks and grommets. The illuminating isolation curtain 2 may be disposed about the track 12 such that it forms an enclosure or isolated working area 20. The illuminating isolation curtain 2 may be configured to move about the track 12 to allow for an opening in the front or back of the working area 20 for easy ingress and egress. Velcro® or other known securing means may couple different curtain walls 4 of the illuminating isolation curtain 2 together during repair to ensure proper isolation of the work area 20. The track 12 may be suspended by cables 14 or the like from the ceiling or other overhead structure. The canopy above the working area 20 may be opened or closed and may contain dust extraction systems, ventilation systems, heating and cooling systems, overhead lighting systems, and other like systems.
The curtain wall 4 may comprise an ultraviolet (UV) window section 16 that may allow for persons to see into or out of the working area 20. The UV window section 16 may serve as eye protection for observers viewing a welding process or similar process involving high light intensity. Curtain wall 4 may also comprise a reflective section 18 for reflecting overhead light into the working area 20. Toward the base of the curtain wall 4, a floor sweep section 19 may comprise a weighed hem to ensure proper containment of particulates within the working area 20. The curtain wall 4 may be made of a non-combustible, flame retardant flexible material. The curtain wall 2 may be of any height H or length L.

The vertical pocket 28 may connect the horizontal pockets 26 such that the horizontal pockets 26 may be in electrical communication with one another and a power source (not shown). The vertical pocket 28 may extend downward toward the base of the curtain wall 4 to allow for electrical wires and cords to feed out of the bottom such that they may extend to a power source (not shown) and/or a controller 30. The controller 30 may be used to brighten or dim the illuminating source 10 as appropriate. The controller 30 may be controlled by any means known in the art, such as by a desktop station or wirelessly by an electronic device. It should be noted that the illuminating isolation curtain 2 need not comprise a vertical pocket 28 connecting the illuminating sources 10 as the illuminating sources 10 housed within the horizontal pockets 26 may individually be connected with a power source and/or controller 30.
To conserve energy, sensors 32 may be integral with the LED strips 24 or located elsewhere within the isolated working area 20 to track movement of a repair professional. The sensors 32 may communicate with the controller 30 via a network, including via a wireless network or wired network, such that the controller 30 may adjust the light intensity (lumen output) of the illuminating source 10 in a particular area of the isolated working area 20 (i.e., the illuminating source can be brightened or dimmed). Sensors 32 may also be configured to sense the haziness or dustiness of the isolated working area 20 and communicate with the controller 30 to brighten the area. In the event no motion is detected by sensors 32 in a particular area of the isolated working area 20, the LED strips 24 may be configured to dim or completely shut off

In one embodiment, the LED strips 24 may be situated within the horizontal pockets 26 in a fixed position. The LED strips 24 may emanate light rays 22 in a general lateral direction (or a direction generally parallel with the ground or floor). It will be appreciated that light rays propagate from a light source and that not all light rays may emanate in a lateral direction.
In another embodiment, the individual LEDs of the bottom, mid, and top LED strips 24a, 24b, 24c (collectively LED strips 24) may be configured to adjust their elevation angle (i.e., a polar angle in a two-dimensional polar coordinate system). The elevation angles of the individual LEDs of the LED strips 24 may be controlled by controller 30 via inputs from sensors 32.
In a first example, if a repair professional is sanding the mid section 34b of the vehicle 34, the LEDs of mid LED strip 24b may be configured to remain aligned with horizon B, but the LEDs of bottom LED strip 24a and the LEDs of top LED strip 24c may be configured to adjust their respective elevations to better focus the incident light rays 22 onto the mid section 34b of vehicle 34. Specifically, to better focus the illumination on the mid section 34b, the individual LEDs of top LED strip 24c may adjust their elevation angle by an angle Φc with respect to horizon C and the individual LEDs of bottom LED strip 24a may adjust their elevation angle by an angle θa with respect to horizon A. Angle Φc may be −45° with respect to its corresponding horizon C and angle θa may be 45° with respect to its corresponding horizon A. Horizons A, B, and C are contemplated to be substantially parallel.
In a second example, if a repair professional is sanding the top section 34c of the vehicle 34, the LEDs of top LED strip 24c may be configured to remain aligned with horizon C, but the LEDs of mid LED strip 24b and the LEDs of bottom LED strip 24a may be configured to adjust their respective elevations to better focus the incident light rays 22 onto the top section 34c of vehicle 34. Specifically, to better focus the illumination on the top section 34c, the individual LEDs of mid LED strip 24b may adjust their elevation angle by an angle θb with respect to horizon B and the individual LEDs of bottom LED strip 24a may adjust their elevation angle by an angle θa with respect to horizon A. It is possible that the individual LEDs of top LED strip 24c will be adjusted by an angle θc with respect to horizon C. Moreover, it is contemplated that θa may be greater than θb. For example, θb might be a 45° angle with respect to horizon B and θa might be a 60° angle with respect to horizon A.
In a third example, if a repair professional is sanding the bottom section 34a of the vehicle 34, the LEDs of bottom LED strip 24a may be configured to remain in position, but the LEDs of mid LED strip 24b and the LEDs of top LED strip 24c may be configured to adjust their respective elevations to better focus the incident light rays 22 onto the bottom section 34a of vehicle 34. Specifically, to focus the illumination on the bottom section 34a of the vehicle 34, the individual LEDs of mid LED strip 24b may adjust their elevation angle by an angle Φb and the individual LEDs of top LED strip 24c may adjust their elevation angle by an angle Φc. It is possible that the individual LEDs of bottom LED strip 24a will be adjusted by an angle Φa. Moreover, it is contemplated that Φc may be greater than Φb (in absolute value). For example, Φb might be a −40° angle with respect to horizon B and Φc might be a −65° angle with respect to horizon C.
In another embodiment, the LED strips 24 may be in communication with an electric motor (not shown) that may drive the LED strips about an axis of rotation to adjust the elevation angle of the respective LED strips 24. The LED strips 24 may be configured to rotate about a flexible shaft, for example. When sensors 32 detect motion or conditions of the working area 20, these inputs may be received by the controller 30 such that the elevation angles of the LED strips may better illuminate the particular section of the vehicle 34 being worked on.
Desirably the inside surface of sections 18 and 19 of the curtain wall may have a light color such as white or a reflective interior surface to better illuminate the interior of the work space and an object therein and the exterior surface of these upper and lower sections 18 and 19 may be of a darker color to decrease the adverse visual appearance of dirt, stains, soiling and the like of their exterior surfaces. Desirably the vertical height or extent of the bottom section 19 may be in the range of about 22-34 inches, the vertical extent or height of the transparent or translucent section 16 or 16′ may be in the range of 20-60 inches and the vertical extent or height of the top section 18 may vary and typically will be selected so that when it is suspended in use, such as from a track, ceiling or otherwise, the bottom edge or end 40 of the wall 4 will be closely adjacent to the ground or floor of the work area 20 and if the wall has a flexible seal strip along the bottom edge 40 of section 19 the seal strip will engage the ground or floor of the work area underlying the wall. Typically the overall longitudinal length of the wall 4 may be more than twice the combined transverse or vertical heights of the bottom section 19 and transparent section 16 or 16′.
As shown in
As shown in
Desirably, the curtain wall 4′ has a plurality of spaced apart rows or strips 24 of lights on both sides of this curtain wall which illuminate the work area and any object therein on the side on which the strips 24 of lights are disposed. On both sides of the curtain wall 4′, a plurality of rows or strips 24 of lights desirably extend longitudinally generally parallel to the bottom edge 40 of the curtain wall or generally parallel to the ground or floor of the work area. In addition, or alternatively, spaced apart rows or strips 32 of lights may extend generally vertically with respect to the bottom edge of the curtain wall or the ground or floor surface of the work area associated with the curtain wall. As shown in
Desirably both sides of the exposed surfaces of sections 18 and 19 of this curtain wall 4′ may have a light color such as white or a reflective surface to better illuminate the work areas or bays on each side of this curtain wall and an object therein. Desirably the transverse or vertical height or extent of the bottom section 19 may be in the range of about 22 to 34 inches, the transverse or vertical extent or height of the transparent or translucent section 16′ may be in the range of about 20 inches to 60 inches and the vertical extent or height of the top section 18 may vary and typically will be selected so that when the curtain wall 4′ is suspended in use, such as from a track, ceiling or otherwise, the bottom edge or end 40 of the wall 4′ will be closely adjacent to the ground or floor of the work areas 20. If the wall 4′ has a flexible seal strip along the bottom edge 40 of section 19, the seal strip will typically engage the ground or floor surface of the work areas underlying the wall. Typically the overall longitudinal length of the wall 4′ may be more than twice the combined transverse or vertical height of the bottom section 19 and the transparent or translucent section 16′.
As shown in
As shown in
Desirably each row or strip 24 of lights may be a plurality of LED lights mounted in spaced apart relation on one face of a strip 48 of a flexible and desirably opaque material which may have a white or reflective surface. The transverse width of the interior of the pockets 26 and 28 desirably may be narrow enough relative to the transverse width of the strip 44 to maintain the desired orientation of the LED lights while still permitting the light strip 24 to be inserted into its associated pocket 26 or 28 and removed for any needed service or replacement. Suitable flexible strips of LED lights spaced about ¾ of an inch apart on a flexible opaque white strip about 0.4 of an inch wide are commercially available as part number WFLS-NW300X3 from SuperBriteLEDS.com which also sells suitable power supplies for these LED lights with or without a dimmer and a remote control. In some applications it may be desirable to mount the power supply in a pocket or pouch on the curtain wall 4 or 4′ and in other applications to locate the power supply remote from the curtain wall 4 or 4′ and connect it with the LED light strips with suitable conventional electric wiring.
The words used herein are understood to be words of description and not words of limitation. While various embodiments have been described, it will be apparent to persons of ordinary skill in the art that many variations and modifications are possible without departing from the scope and spirit of the invention as set forth in the appended claims.
