Abstract

A bollard system includes a post extension to extend upward from a floor, a first collar to encircle the post extension, a first connector to encircle the post extension adjacent to the first collar, and a first handrail to be connected to the first connector. The bollard system includes a second connector to encircle the post extension adjacent to the first connector, a second handrail to be connected to the second connector, and a second collar to encircle the post extension adjacent to the second connector. The first collar is invertible selectively to a first lock position and a first release position, the first connector having greater freedom to rotate relative to the first collar when the first collar is in the first release position than when the first collar is in the first lock position.

First claim

What is claimed is:

1. A barrier system mountable to a floor, the barrier system comprising:
a post extension to extend upward from the floor;
a first collar to fully encircle the post extension, the first collar corresponding to a first unitary component;
a first connector to fully encircle the post extension adjacent to the first collar, the first collar having a different shape than the first connector, the first connector corresponding to a second unitary component different than the first unitary component;
a first handrail to be connected to the second unitary component, the first handrail to be spaced apart from the first unitary component, the first handrail to be substantially perpendicular to the post extension;
a second connector to fully encircle the post extension adjacent to the first connector such that the first connector is interposed between the first collar and the second connector; and
a second handrail to be connected to the second connector, the second handrail to be substantially perpendicular to the post extension, the first collar being invertible selectively to a first lock position and a first release position, the first connector having greater freedom to rotate relative to the first collar when the first collar is in the first release position than when the first collar is in the first lock position.

2. The barrier system of claim 1 , wherein the first handrail is rotatable about the post extension when the first collar is in the first release position.

3. The barrier system of claim 1 , further including an anti-rotation key extending from one of the first connector and the first collar, the anti-rotation key to engage both the first connector and the first collar when the first collar is in the first lock position, the anti-rotation key being spaced apart from at least one of the first collar or the first connector when the first collar is in the first release position.

4. The barrier system of claim 3 , wherein the anti-rotation key points in a substantially vertical direction when the first collar is in the first lock position, and the anti-rotation key points in a substantially opposite vertical direction when the first collar is in the first release position.

5. The barrier system of claim 3 , wherein the first collar includes a first surface and a second surface such that when the first collar is in the first lock position the first surface faces upward and the second surface faces downward, and when the first collar is in the first release position the first surface faces downward and the second surface faces upward.

6. The barrier system of claim 3 , wherein the anti-rotation key is an integral extension of the first collar such that the first collar and the anti-rotation key is a seamless unitary piece.

7. The barrier system of claim 1 , further including a second collar to encircle the post extension adjacent to the second connector such that the second connector is interposed between the second collar and the first connector.

8. The barrier system of claim 7 , wherein the second collar is to be higher than the first collar.

9. The barrier system of claim 7 , wherein the second collar is invertible selectively to a second lock position and a second release position, the second connector having greater freedom to rotate relative to the second collar when the second collar is in the second release position than when the second collar is in the second lock position.

10. The barrier system of claim 1 , further including:
a first support member to extend from the first connector, the first handrail to rest upon the first support member; and
a second support member to extend from the second connector, the second handrail to rest upon the second support member, a first upper surface of the first handrail to be at a first elevation that is higher than a first lower surface of the second handrail when the first handrail and the second handrail are resting on the respective first and second support members, a second upper surface of the second handrail to be at a second elevation that is higher than a second lower surface of the first handrail when the first handrail and the second handrail are resting on the respective first and second support members.

11. The barrier system of claim 1 , wherein the post extension has selectively a first mounting configuration and a second mounting configuration, the post extension to be vertically elongate in both the first mounting configuration and the second mounting configuration, the post extension in the first mounting configuration engaging a post extending upward from the floor, the post extension in the second mounting configuration being fastened to the floor and not engaging the post.

12. The barrier system of claim 1 , further including a retainer on the first connector to selectively restrict movement of and release an end of the first handrail, the retainer including a spring to bias the retainer in a position to restrict movement of the end of the first handrail.

13. The barrier system of claim 12 , wherein the retainer includes a cross-section that varies in size along a length of the retainer.

14. The barrier system of claim 1 , wherein the first handrail includes an end section and a central section, the end section being adjustable relative to the central section to change a length of the first handrail.

15. The barrier system of claim 1 , wherein the first collar includes a first surface facing in a first direction and a second surface in a second direction, the first surface to abut a mating surface of the first connector when the first collar is in the first lock position, the second surface to abut the mating surface of the first connector when the first collar is in the first release position.

16. The barrier system of claim 15 , wherein the first collar includes an anti-rotation key protruding from the first surface, the anti-rotation key to engage a key slot in the mating surface of the first connector when the first collar is in the first lock position.

17. The barrier system of claim 1 , wherein the first connector includes a socket to capture an end of the first handrail, the socket defined by an elongate channel having a channel length extending between a first end of the channel and a second end of the channel, the first end of the channel being open to enable the end of the first handrail to be inserted into the channel, the second end of the channel being blocked by a plate to prevent passage of the end of the first handrail.

18. The barrier system of claim 17 , further including a retainer to selectively extend into a side of the channel to restrict movement of the first end of the first handrail along the channel.

19. The barrier system of claim 18 , wherein the retainer is spaced apart from the plate sufficiently to enable the first end of the first handrail to be disposed within the channel between the plate and the retainer.

20. The barrier system of claim 17 , wherein the end of the first handrail includes a ball to slidingly fit into the channel of the socket.

21. The barrier system of claim 17 , wherein the channel is to extend substantially parallel to the post extension when the first connector encircles the post extension.

22. The barrier system of claim 17 , wherein the first connector is to encircle the post extension with a portion of the first connector, the portion to extend a first length along the post extension, the first length being shorter than the channel length, t
