10. The protective barrier of claim 9 further comprising one or more elastic members configured to rest on the attachment surface with a corresponding one of the fasteners extending therethrough.

11. The protective barrier of claim 10 wherein each of the one or more elastic members has a washer disposed thereon and the elastic member is held captive between the washer and the attachment surface.

12. The protective barrier of claim 1 wherein the first strap retaining mechanism is disposed within the first rail receiving member.

13. The protective barrier of claim 1 further comprising a second strap retaining mechanism for securing a second distal end of the strap, opposite the first distal end of the strap, within the protective barrier.

14. The protective barrier of claim 12 wherein the second strap retaining mechanism is disposed within the second rail receiving member.

15. The protective barrier of claim 1 wherein the first rail receiving member includes a covered opening for providing access to the first strap retaining mechanism.

DETAILED DESCRIPTION

1 Overview

[0023] Referring to FIGS. 1 and 2, a barrier 100 includes a rail 102 extending between two end pieces 104, which are anchored to a surface. A strap system 206 extends between the end pieces 104 through the rail 102. The strap system 206 includes two strap retention mechanisms 208, each holding a different distal end of a strap 210. The strap retention mechanisms 208 are configured for installation inside the end pieces 104. The strap 201 is configured to extend through the rail 102.

[0024] Referring to FIGS. 3-6, the strap retention mechanism 208 includes an attachment flange 316, a strap retention portion 312, and an upright portion 314 extending between the attachment flange 316 and the strap retention portion 312. The strap retention portion 312 includes a curved strap support surface 320 and a friction plate 322 that is configured to be tightened down toward the strap support surface 320 using screws 324. The friction plate 322 includes a first opening 326 configured to receive a loose end of the strap 310. In general, the attachment flange 316 includes one or more through holes 318 for receiving fasteners to secure the attachment flange 316 to the surface. The upright portion 314 includes a second opening 328 for receiving a loose end of the strap 310.

[0025] In some examples, the barrier 100 is installed by positioning the end pieces 104 in their desired location and then positioning the strap retention mechanism 208 within the end pieces 104. Fasteners are inserted through the through holes 318 in the attachment flange 316, through openings in bottom surfaces of the end pieces 104 and secured into the surface. In some examples, the fasteners also extend through a shock absorber, as is described in greater detail below.

[0026] With the end pieces 104 and strap retention mechanisms 208 installed, the strap 110 (e.g., a nylon strap) is threaded through the rail 102 and installed in the strap retention mechanisms 208. To install the strap 310 in the strap retention mechanisms 208, each of the distal ends of the strap 110 is threaded between the curved strap support surface 320 and the friction plate 322 of a respective strap retention mechanism 208. The screws 324 are then tightened to move the friction plate 322 such that it pinches and holds the strap 310 (e.g., by friction) between the friction plate 322 and the curved strap support surface 320. The ends of the strap 310 are further secured by threading them through the first opening 326 in the friction plate 322 and then through the second opening 328 in the upright portion 314.

[0027] In some examples, one distal end of the strap 310 is fully installed in one of the strap retention mechanisms 208 prior to the other distal end being installed in another strap retention mechanism 208. This allows for effective tightening of the strap 310 during installation.

[0028] Referring to FIGS. 7-11, the strap system 206 can be used in multiple configurations, such as in longer, segmented barriers and barriers including angles (e.g., 90-degree turns) as in FIG. 7. In some examples, the attachment flange of the strap retention mechanisms is offset to accommodate different angles when used in angled barriers as in FIG. 9. In some examples, when two segments are connected end-to-end, the attachment flanges of the strap retention mechanisms are attached together and to the surface. As is mentioned above, in some examples the attachment flanges of the strap retention mechanisms are coupled to the surface using an impact absorber 932 as in FIGS. 9-11.

[0029] In some examples, the strap retention mechanisms are accessible through openings in the end pieces or other segment connecting pieces (e.g., center and angle connectors) of the barriers.

[0030] In some examples, only a single strap retention mechanism is used, and a fixed or relatively more permanent strap connection is used on the opposite end of the strap.

[0031] A number of embodiments of the invention have been described. Nevertheless, it is to be understood that the foregoing description is intended to illustrate and not to limit the scope of the invention, which is defined by the scope of the following claims. Accordingly, other embodiments are also within the scope of the following claims. For example, various modifications may be made without departing from the scope of the invention. Additionally, some of the steps described above may be order independent, and thus can be performed in an order different from that described.
