BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a highway safety net for use in connection with shock absorbing devices. The highway safety net has particular utility in connection with self supporting highway barricade net.

2. Description of the Prior Art

Highway safety nets are desirable for catching and stopping out of control vehicles at grass highway medians.

The use of shock absorbing devices is known in the prior art. For example, U.S. Pat. No. 2,465,936 to Schultz discloses an emergency arresting device for moving objects that comprises a pair of supports and a plurality of horizontal plies attached to the supports. The horizontal plies being constructed of a synthetic plastic material susceptible of at least 100% permanent elongation. However, the Schultz '936 patent does not have a net connected to spaced posts wherein a heavy cable is connected to the net and has stabilizer bars connecting the cable to the spaced posts.

Similarly, U.S. Pat. No. 3,468,500 to Carlsson discloses an arresting gear for aircraft and other vehicles that comprises a net having upper and lower cables. The upper cable consists of a plurality of separate lines or strands. Vertical lines connect the upper and lower cables. Each of the vertical lines is connected at one end to a single one of the strands of the upper cable. However, the Carlsson '500 patent does not have a net connected to spaced posts wherein a heavy cable is connected to the net and has stabilizer bars connecting the cable to the spaced posts.

Lastly, U.S. Pat. No. 3,367,608 to Charno, et al. discloses a barricade net arresting system that is designed to raise and lower a cross-runway barricade member such as a textile net adapted to be engaged by a distressed aircraft which would otherwise over run the safe limits of the runway. A pair of stanchions at opposite sides of the runway support the net. Each stanchion is operated by a hydraulic system synchronized by a unified control. A cylinder is actuated by the hydraulic fluid to raise or lower each stanchion in unison. A feature of each hydraulic system includes an automatic accumulator and recharge. However, the Charno, et al. '608 patent does not have a net connected to spaced posts wherein a heavy cable is connected to the net and has stabilizer bars connecting the cable to the spaced posts.

While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a highway safety net that allows self supporting highway barricade net. The Schultz '936, Carlsson '500 and Charno, et al. '608 patents make no provision for a net connected to spaced posts wherein a heavy cable is connected to the net and has stabilizer bars connecting the cable to the spaced posts.

Therefore, a need exists for a new and improved highway safety net which can be used for self supporting highway barricade net. In this regard, the present invention substantially fulfills this need. In this respect, the highway safety net according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of self supporting highway barricade net.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of shock absorbing devices now present in the prior art, the present invention provides an improved highway safety net, and overcomes the above-mentioned disadvantages and drawbacks of the prior art. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved highway safety net and method which has all the advantages of the prior art mentioned heretofore and many novel features that result in a highway safety net which is not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or in any combination thereof.

To attain this, the present invention essentially comprises netting connected to a lower cable. A first post top is connected to the netting for supporting the netting. A second post top is connected to the first post top. A first stabilizer bar is connected to the lower cable. The first stabilizer bar is connected adjacent to the first post bottom. A second stabilizer bar is connected to the lower cable. The second stabilizer bar is connected adjacent to the second post bottom.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.

The invention may also include a catch, a first stabilizer hook, a second stabilizer hook, a first cement footing, a second cement footing and cable weights. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings, and particularly to FIGS. 1-4, a preferred embodiment of the highway safety net of the present invention is shown and generally designated by the reference numeral 10.

In FIG. 1, a new and improved highway safety net 10 of the present invention for self supporting highway barricade net is illustrated and will be described. More particularly, the highway safety net 10 has a netting 14 connected to a lower cable 12 (shown in FIG. 2). A first post top 18 is connected to the netting 14 for supporting the netting 14. A second post top 24 is connected to the first post top 18.

In FIG. 2, the highway safety net 10 is illustrated and will be described. More particularly, the highway safety net 10 has the netting 14 connected to the lower cable 12. The lower cable 12 is steel braid in the present example. A first post 16 has the first post top 18 and a first post bottom 20. The first post top 18 is connected to the netting 14 for supporting the netting 14. A second post 22 has the second post top 24 and a second post bottom 26. The second post top 24 is connected to the first post top 18. A first stabilizer bar 28 is rotatably connected to the lower cable 12. The first stabilizer bar 28 is connected adjacent to the first post bottom 20. A second stabilizer bar 30 is rotatably connected to the lower cable 12. The second stabilizer bar 30 is connected adjacent to the second post bottom 26. A catch 32 is connected to the first post top 18. The catch 32 is connectable to the second post top 24. The catch 32 is for supporting the net 14. A first stabilizer hook 34 is connected to the first post 16. The first stabilizer hook 34 is detachably connectable to the first stabilizer bar 28. A second stabilizer hook 36 is connected to the second post 22. The second stabilizer hook 36 is detachably connectable to the second stabilizer bar 30. A first cement footing 38 is connected to the first post bottom 20. A second cement footing 40 is connected to the second post bottom 26.

In FIG. 3, the highway safety net 10 is illustrated and will be described. More particularly, the highway safety net 10 has the netting 14 connected to the lower cable 12. The first stabilizer bar 28 is rotatably connected to the lower cable 12.

In FIG. 4, the highway safety net 10 is illustrated and will be described. More particularly, the highway safety net 10 has the netting 14 connected to the lower cable 12. A plurality of cable weights 42 are connected to the lower cable 12 in the second embodiment. Those skilled in the art will readily recognize that a strong, heavy cable or other anchoring devices could be used in place of said plurality of cable weights 42 without deviating from the spirit and scope of the invention.

In use it can now be seen that in the event a driver is involved in an event in which the vehicle suddenly steers into the grass median and towards the opposite direction of traffic, it would be intercepted by the highway safety net 10. Once the vehicle strikes the strong webbing the weight of the lower cable 12 would drag the vehicle to a stop. The vehicle thus would be quickly decelerated and stopped in a safe and controlled manner before it could enter the opposite direction of traffic and cause a major accident.

While a preferred embodiment of the highway safety net has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. For example, any suitable sturdy material such as composite mesh may be used instead of the metal netting described. And although self supporting highway barricade net have been described, it should be appreciated that the highway safety net herein described is also suitable for arresting aircraft which go beyond the tarmac.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
