LED-ILLUMINATED CAUTION AND DISPLAY DEVICES

Abstract

A caution device and a display device are used to draw attention to either a hazardous area, e.g., a construction zone, or a desired event, e.g., a grand opening. The devices are visible during daylight but are also equipped with LEDs to illuminate during twilight, dark, and inclement weather. The devices are preferably reusable.

DETAILED DESCRIPTION OF THE INVENTION

[0031] While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail at least one preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to any of the specific embodiments illustrated.

[0032] Referring to FIGS. 3-8, embodiments of the banner display device 10 (see FIGS. 3A-B, 5A-B) and caution tape device 12 (see FIGS. 4A-B, 6A-B, 7A-B, 8A-B) are illustrated. Both devices are comprised of a long body portion and a functioning lighting element, as will be explained further below. Preferably, a strand of LEDs is used to provide illumination, but other low-heat lighting sources may be used as well.

[0033] In the case of the banner display device 10, it is comprised of a long plastic strip body 20 to which a plurality of flag/banners 22 are attached in succession. A cord or rope 24 is typically threaded through the plastic strip body 20 to allow ends to be tied off to a structure (e.g., see FIG. 2). These banner displays 10 are well-known in the art.

[0034] However, preferably within the plastic strip body 20 a strand of LEDs 26 is inserted. The LEDs 26 may be intermittently placed in regular or irregular intervals, preferably two to eight inches apart. Other spacings may also be suitable for specific uses. The LEDs 26 may only need to be run through a portion of the entire strip body 20, such as the ends or a middle section. The LEDs 26 are preferably connected to a power source (not shown), such as an AC cord or a rechargeable DC battery pack. To conserve power, the LEDs 26 may also be connected to a light-sensor (not shown) which controls power to turn the LEDs 26 on only when visibility is low.

[0035] FIGS. 5A and 5B show a preferred construction of the display banner device 10.

[0036] Likewise, the caution tape device 12 has a long body 30 comprised of typical caution tape. The tape is typically 2-5 inches wide with black lettering. This general device is also well-known to those skilled in the art.

[0037] However, the device 12 of the present invention includes a strand of LEDs 36 spaced along an edge of the tape, as shown in FIG. 4A. The LEDs 36 may be intermittently placed in regular or irregular intervals, preferably two to eight inches apart. Other spacings may also be suitable for specific uses. The LEDs 36 may only need to be run through a portion of the entire body 30, such as the ends or a middle section. The LEDs 36 are preferably connected to a power source (not shown), such as an AC cord or a rechargeable DC battery pack. To conserve power, the LEDs may also be connected to a light-sensor (not shown) which controls power to turn the LEDs on only when visibility is low.

[0038] FIGS. 6A and 6B show a first preferred construction of the caution tape device 12. The first embodiment loops a top edge of the tape over and a single line of longitudinal stitching to create a channel 32 for the LED strand 36. Alternatively, FIGS. 7A and 7B show the use of a narrow plastic strip 34 attached to the top edge of the tape with double longitudinal stitching to create a channel 32 for the LED strand 36.

[0039] Finally, in another preferred embodiment of the caution tape device, FIGS. 8A and 8B show a bottom-mounting for the plurality of LEDs 36. In this embodiment, a separate material strip 38 is stitched into and along the bottom edge of the body 30 to create a channel 32 for the LED strand 36. In this embodiment, the weight of the LED strand 36 along the bottom of the device helps prevent rolling over of the device 12.

[0040] The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of applicants' contribution. The actual scope of the protection sought is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
