Abstract

A hand rail to post connector assembly for use with a modular ramp. The assembly includes a post cap configured for mounting to a post, a saddle that is received by a slot in the post cap, and a rail insert that is secured to the saddle. The post cap includes a support surface configured to support a hand rail, and the post cap substantially constrains the saddle from moving vertically. The rail insert has a clamping surface that engages an inner surface of the hand rail for clamping the hand rail between it and the saddle.

Claims

1. A hand rail to post connector assembly, comprising:

a post cap configured for mounting to a post, wherein said post cap comprises a support surface configured to support a hand rail, and a slot positioned below said support surface;

a saddle configured to be received by said slot such that said post cap substantially constrains said saddle from moving vertically; and

a rail insert comprising a clamping surface configured to engage an inner surface of a hand rail, wherein said rail insert is configured to be secured to said saddle for clamping the hand rail between said rail insert and said saddle.

2. The assembly of claim 1, wherein said post cap comprises a locking structure that is coupled with and extends downward from said support surface, wherein said locking structure defines said slot.

3. The assembly of claim 2, wherein said post cap comprises opposed side walls each coupled with said support surface, wherein said side walls are configured for mounting to a post.

4. The assembly of claim 1, wherein said support surface is configured to prevent lateral and downward movement of the hand rail.

5. The assembly of claim 1, wherein said support surface is curved for supporting a hand rail having a circular cross-section.

6. The assembly of claim 1, wherein said slot is configured to slideably receive said saddle in a substantially horizontal direction.

7. The assembly of claim 1, wherein said saddle comprises an opening that is configured to align with an opening in the hand rail, and wherein said rail insert comprises a protrusion that extends downward from said clamping surface and is received by the aligned openings.

8. The assembly of claim 7, wherein said protrusion comprises a threaded fastener which engages a first nut that abuts a lower surface of said saddle for clamping the hand rail between said rail insert and said saddle.

9. The assembly of claim 8, wherein said saddle comprises an upper surface with a recess formed therein that surrounds said opening in said saddle, and further comprising a second nut that engages said threaded fastener and is received by said recess.

10. The assembly of claim 7, wherein said saddle is longer than said post cap such that a portion of said saddle including said opening extends laterally from said post cap.

11. The assembly of claim 1, wherein said rail insert is configured to be received within a hand rail.

12. The assembly of claim 1, wherein said clamping surface is curved for engaging the inner surface of a hand rail having a circular cross-section.

13. The assembly of claim 1, further comprising a second rail insert comprising a clamping surface configured to engage an inner surface of a second hand rail, wherein said second rail insert is configured to be secured to said saddle for clamping the second hand rail between said second rail insert and said saddle.

14. A post and hand rail assembly, comprising:

a post;

a post cap mounted to said post, wherein said post cap comprises a support surface and a slot positioned below said support surface;

an upper hand rail comprising an outer surface that is supported by said support surface and an inner surface;

a saddle that is configured to be received by said slot such that said post cap substantially constrains said saddle from moving vertically; and

a rail insert comprising a clamping surface engaging said inner surface of said upper hand rail, wherein said rail insert is secured to said saddle for clamping said upper hand rail between said rail insert and said saddle.

15. The assembly of claim 14, wherein said post comprises opposed side walls each having an opening, and further comprising a lower hand rail that is received by said opening in each of said side walls.

16. The assembly of claim 15, further comprising a second post mounted to said post cap, wherein said second post comprises opposed side walls each having an opening, and further comprising a second lower hand rail that is received by said opening in each of said side walls of said second post.

17. The assembly of claim 16, further comprising a post channel coupled with said post and said lower hand rail via a first fastener that is received by aligned holes in said post channel, said post, and said lower hand rail, and wherein said post channel is coupled with said second post and said second lower hand rail via a second fastener that is received by aligned holes in said post channel, said second post, and said second lower hand rail.

18. The assembly of claim 16, further comprising a second upper hand rail comprising an outer surface that is supported by said support surface and an inner surface, and a second rail insert comprising a clamping surface engaging said inner surface of said second upper hand rail, wherein said second rail insert is secured to said saddle for clamping said second upper hand rail between said second rail insert and said saddle.

19. The assembly of claim 18, wherein said saddle comprises a first opening that aligns with an opening in said upper hand rail and a second opening that aligns with an opening in said second upper hand rail, wherein said rail insert comprises a protrusion that extends downward from said clamping surface and is received by the aligned first opening and opening in said upper hand rail, and wherein said second rail insert comprises a protrusion that extends downward from said clamping surface and is received by the aligned second opening and opening in said second upper hand rail.

20. The assembly of claim 19, wherein said saddle is longer than said post cap such that a portion of said saddle including said first opening extends laterally from one end of said post cap and a portion of said saddle including said second opening extends laterally from another end of said post cap.

21. A modular ramp assembly, comprising:

a ramp comprising a substantially planar surface and a pair of frame rails each joined with one side of said planar surface;

a post mounted to one of said frame rails;

a post cap mounted to said post, wherein said post cap comprises a support surface and a slot positioned below said support surface;

an upper hand rail comprising an outer surface that is supported by said support surface and an inner surface;

a saddle that is configured to be received by said slot such that said post cap substantially constrains said saddle from moving vertically; and

a rail insert comprising a clamping surface engaging said inner surface of said upper hand rail, wherein said rail insert is secured to said saddle for clamping said upper hand rail between said rail insert and said saddle.
