Description

BARRIER DEVICE AND METHOD OF PROVIDING A BARRIER

CROSS REFERENCE TO RELATED APPLICATION This application claims the benefit of U.S. Provisional Patent application number 60/127,697 filed April 5, 1999.

BACKGROUND OF THE INVENTION

1. Field Of The Invention

The present invention relates generally to a barrier device and a method of providing a barrier to a structure, such as a bridge. The present invention is capable of being used in conjunction with a guardrail structure commonly found on automobile bridges.

2. Discussion of Related Art In the prior art, there are devices for universally mounting a barrier structure. One such barrier structure is sandwiched between a plurality of pairs of channel members which pairs are spaced over the length thereof. The channel members are sized so that they may be nested for receiving a flexible barrier structure or positioned back-to-back for receiving a rigid barrier structure. For use as a guardrail barrier structure, each pair of channel members is attached to a flange on a mounting bracket which is attached to the guardrail and extends laterally therefrom to the flange. The bracket may be rotated 90 degrees for mounting to a vertical as well as a horizontal guardrail. The mounting bracket is attached to a guardrail engaging strap for mounting thereof to the guardrail. The mounting bracket is provided with several spaced apertures so that it may be attached to straps of various sizes for application to various sized guardrails whereby the mounting apparatus may be simple yet effective and universally mountable. For use as a snow fence or the like, one of each pair of channel members is mounted as a post in the ground whereby the pair of channel members may be free-standing. Such prior art devices have deficiencies. For example, they require many parts and rely on friction to hold the barrier in place.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention provides a device which can be attached to a structure, such as the support structure of a guardrail of a bridge. Figures 1 and 2 show a side view of a bridge having a bridge deck 10 and two guardrails 13, 14 mounted on a guardrail support 16. The guardrail support 16 is shown attached to the bridge deck 10 via deck bolts 19, 20. The guardrail support 16 includes rail flanges 22, 23, rail nuts 25, 26 and rail bolts 28, 29 for attaching the guardrails 13, 14 to the guardrail support 16. Attached to the guardrail support 16 is a bracket 30. As best seen in Figures 3-8, the bracket 30 includes bracket flanges 31, 32 and a bracket base 34. Figures 3-5 depict an embodiment of the bracket 30. Figures 6-8 depict an alternative embodiment of the bracket 30.

The bracket flanges 31, 32 are connected to the guardrails 13, 14, for example via rail nuts 25, 26 and rail bolts 28, 29, as shown in Figures 1 and 2. In the embodiment shown in Figures 1 and 2, the bracket flanges 31, 32 extend from the rail bolts 28, 29 through the guardrail support 16 to the bracket base 34. A barrier fence 37 is provided proximate to, but preferably in contact with, the bracket base 34. The barrier fence 37 may have an open mesh, such as a chain link fence, or may be another type of barrier.

A clamping member 39, shown in Figures 9 and 10, is also positioned proximate to, but preferably in contact with, the barrier fence 37. An alternative embodiment of the clamping member 39 is shown in Figures 11 and 12. The barrier fence 37 may be attached as shown in Figures 1 and 2 with fence bolts 40, 41, which extend through base holes 43A, 44A in the bracket base 34, and through member holes 43B, 44B in the clamping member 39, combined with fence nuts 46, 47.

It should be noted that the bracket base 34 can nest with the clamping member 39. Figures 13 and 14 show a device in which the bracket base 34 is nested with the clamping member 39. Figures 15 and 18 show alternative embodiments of the present invention in which the bracket base 34 is nested with the clamping member 39. The tines 48 of the bracket base 34 may reside between the fingers 49 of the clamping member, as shown in Figure 14, or the fingers 49 may reside between the tines 48, as shown in Figures 15 and 18. The nesting feature allows the barrier fence 37 to be pulled taught simply by moving the clamping member 39 closer to the bracket base 34. In the embodiments shown, the clamping member 39 is moved closer to the bracket base 34 by tightening the fence bolts 40, 41 and fence nuts 46, 47.

Figures 1 and 2 depict an embodiment of the present invention in which the bracket base 34 resides between the barrier fence 37 and the guardrail support 16. In contrast to Figures 1 and 2, Figures 13 and 14 show an embodiment of the present invention in which the barrier fence 37 is positioned between the bracket base 34 and the guardrail support 16. In this embodiment, the bracket flanges 31, 32 extend through the barrier fence 37. The clamping member 39 may then be attached to the bracket base 34, for example, via the fence nuts 46, 47 and the fence bolts 40, 41.

An alternative embodiment of the present invention shown in Figure 15 includes a cable 54. The cable 54 may be a one-quarter inch diameter steel cable. A first end 57 and a second end 60 of the cable 54 are secured to the barrier fence 37, such as by weaving the ends 57, 60 through the barrier fence 37. Between the ends 57, 60, the cable 54 runs around at least a portion of the rail bolt 29. A similar arrangement may be provided with regard to the rail bolt 28 and another cable similar to cable 54. In this manner, the cable 54 provides support for the barrier fence 37. Figures 16-18 illustrate a variation of the alternative embodiment of the invention shown in Figure 15. Figure 16 is an exploded side view of a bracket 30 according to the present invention. The bracket 30 shown in Figures 16 and 17 includes one or more eyelets 63A, 63B on the bracket flange 31 for receiving a cable 54A. The bracket 30 shown in Figures 16 and 17 also may include another eyelet 64 on the bracket flange 32 for receiving a cable 54B. In a modified version of the bracket 30 shown in Figures 16 and 17, the bracket 30 may include two eyelets 63A, 63B on the bracket flange 31. The bracket flange 32 may similarly include two eyelets.

Figures 16-18 show another way of attaching the present invention. As best seen in Figure 18, a strap

67 envelopes a portion of the guard rail support 16, and the strap 67 is attached to the bracket flange 30 by threaded ends 70 of the strap 67, which extend through the bracket flange 30 and are fixed in place by nuts 73. Figure 19 describes one method of installing the device described above. In the method a bracket, similar to the bracket 30 described above, is provided (step 100) . Then, the bracket is attached (step 103) to the structure by, for example, (A) inserting the bracket flanges 31, 32 through the guardrail support 16, and so that one of the flange holes 50A, 51A, 52A on bracket flange 31 is aligned with rail bolt 28; (B) inserting the rail bolt 28 through one of the flange holes 50A, 51A 52A and then threading the rail nut 25 onto the rail bolt 28 to hold the guardrail 13 and the bracket flange 31; (C) aligning one of the flange holes 50B, 51B, 52B on bracket flange 32 with rail bolt 29, and inserting rail bolt 29 through one of the flange holes 50B, 51B and 52B; and (D) threading rail nut 26 onto rail bolt 29 to hold the guardrail 14 and the bracket flange 32.

Then a barrier, such as the barrier fence 37, is provided proximate to the base (step 106), and a clamping member, such as the clamping member 39 described above, is provided proximate to the barrier (step 109) . Finally, a rod, such as the fence bolt 40, is provided (step 112) and inserted (step 115) through the clamping member, the barrier and the base. This may be done by inserting the fence bolts 40, 41 through the member holes 43B, 44B in the clamping member 39, through the barrier fence 37, and then through base holes 43A, 44A in the bracket base 34. The fence nuts 46, 47 may then be threaded onto the fence bolts 40, 41 to secure the barrier fence 37 between the bracket base 34 and the clamping member 39. Figure 1 shows a device assembled according to such a method. In another method according to the present invention, described in Figure 20, a bracket similar to that described above is provided (step 100), and a barrier is provided (step 106) . Then a portion of the bracket, such as the bracket flanges 31, 32 are inserted (step 150) through the barrier, and the flanges 31, 32 are attached (step 103) to the structure, for example to a guardrail in the manner provided above. Then, a clamping member may be provided (step 109) proximate to the barrier, and preferably such that the clamping member partially surrounds the bracket base, as shown in Figure 14. Finally, if provided, the clamping member is connected to the base (step 153) . If desired, the fence bolts 40, 41 are inserted through the holes 43B, 44B in the clamping member 39, through the holes 43A, 44A in the bracket base 34 and through the barrier fence 37. Next, the fence nuts 46, 47 are threaded onto the fence bolts 40, 41 to secure the fence bolts 40, 41. Figure 13 shows a device assembled in this manner. Although the present invention has been described with respect to one or more particular embodiments, it will be understood that other embodiments of the present invention may be made without departing from the spirit and scope of the present invention. Hence, the present invention is deemed limited only by the appended claims and the reasonable interpretation thereof.
