Description
- This application is a continuation of U.S. patent application Ser. No. 13/532,158 filed Jun. 25, 2012, which is a continuation-in-part of U.S. patent application Ser. No. 13/216,426 filed Aug. 24, 2011, entitled “Portable Height Adjustable Barrier for Screening Off the Source of Traffic Congestion,” the contents of which are incorporated by reference herein.
- The present invention is generally directed to a portable and wind-resistant barrier for visually screening areas from motorists to reduce “gawking” and resultant traffic congestion and related method.
- Vehicular traffic congestion often occurs as road use increases, such as during peak travel times. Such congestion is characterized by slower speeds, longer travel times, and often a sense of driver frustration. Causes of traffic congestion, or “traffic jams” may include, among other things, roadwork, detours, increased traffic volume such as during “rush hour”, and vehicle accidents.
- Regardless of cause, traffic congestion is often exacerbated due to drivers slowing down to observe vehicles on the side of the roadway. This “gawking” or “rubber-necking” typically occurs when drivers slow to observe car accidents, wreckage, and emergency response vehicles. Such gawking often magnifies traffic congestion.
- Besides merely extending driving times and inducing driver frustration, increased congestion due to gawking also creates costs related to non-productivity. Such delays are often responsible for lost business, job-related disciplinary action, and other personal losses. Inability to forecast travel times causes drivers to allocate more time to travel, additionally resulting in productivity losses. Increased wear and tear to vehicles is yet another cost incurred by those caught in traffic. Finally, longer commutes due to gawking harm the environment due to increased air pollution and carbon dioxide emissions.
- While gawking continues to be a significant contributor to traffic congestion, very little has been done to alleviate this problem.
- In view of the foregoing background, it is therefore an object of the present invention to provide a portable traffic vision screen to prevent or reduce traffic gawking, thereby reducing a primary cause of vehicular traffic congestion. Such a screen should be adjustable, scalable, and wind-resistant. Moreover, such screen should be free-standing.
- The invention contemplates a wind-resistant portable traffic screen comprising a screen for the purpose of visually occluding one's view of matter behind the screen. A substantially vertical member holds the screen, and a fastener with the screen removably attaches the screen to the vertical member. The screen partially disengages from the vertical member upon exposure to a sufficient wind current. The purpose the disengaging screen is to reduce wind pressure exerted upon the screen and the vertical member. The screen re-engages the vertical member when the pressure from the wind current wanes.
- In one embodiment of the portable traffic screen, a first and second support tube each have a top and bottom end. First and second inner retractable support tube extensions extend out of the top end of the first support tube and the second support tube, respectively. A retractable tripod assembly attaches to the bottom end of each support tube, and is situated to maintain the support tubes in a substantially vertical and free-standing orientation when the tripod assembly is in an expanded state. Ballast in communication with the tripod provides stability to the tripod assembly. The foldable screen has an upper edge, opposing lower edge, a side edge, and an opposing side edge, wherein the screen is attachable substantially between the support tubes.
- Additionally, a magnet is in communication with each side edge of the screen, the magnet placed for removably attaching each side edge to a proximate support tube. The magnet is capable of partially disengaging the screen from the support tubes to relieve pressure exerted by a wind current.
- The portable traffic screen further comprises a second foldable screen having a second upper edge, second opposing lower edge, second side edge, and a second opposing side edge, wherein the second screen is attachable substantially between the support tubes. A second magnet is in communication with each second side edge of the second screen, the second magnet placed for removably attaching each second side edge to a proximate support tube. The second magnet is capable of partially disengaging the second screen from the support tubes to relieve pressure exerted by a wind current.
- In yet another embodiment, a portable traffic screen comprises a first and second extendable support tube. Each tube has a top and bottom end and each tube has a ferrous region. A hub is attached to each support tube, each hub having a size and dimension to engage a crossmember. A retractable tripod assembly is attached to the bottom end of each support tube, and the tripod assembly is situated for maintaining the support tubes in a substantially vertical, free-standing, orientation when the tripod assembly is in an expanded state. A foldable screen is attachable between the support tubes. Additionally, a substantially rigid crossmember attaches proximate a top edge of the screen, the crossmember being attachable to each hub.
- A magnet is attached to a peripheral region of the screen, the magnet being positioned for removably attaching the peripheral region to the ferrous region of a proximate support tube. The magnet is capable of temporarily disengaging the screen from the support tubes to relieve pressure exerted upon the screen being created by a wind current. A cable attached between the screen and a support tube is present for limiting a distance the screen travels when the screen is temporarily disengaged from the support tube due to a wind current.
- The invention also contemplates a method of assembling the traffic screen comprising the steps of expanding the tripod assembly of each support tube; standing each support tube in a substantially vertical orientation; extending each support tube; attaching the crossmember to the hub of each support tube; and attaching the cable to at least one support tube.
- The method of assembling the traffic screen may also comprise the step of attaching a ballast proximate at least one tripod assembly and/or the step of adjusting the length of the cable.
- For a fuller understanding of the invention, reference is made to the following detailed description, taken in connection with the accompanying drawings illustrating various embodiments of the present invention, in which:
