Abstract

An improved fastening system is provided for anchoring a post to a foundation, in which the fastening system is received and completely concealed within a recess formed between the post and the foundation. The fastening system of this invention also provides for an improved method for installing a post, by which the post is threadably secured to the foundation by being rotated relative to the foundation. The fastening system includes a first member securable to a lower surface of the post, and a second member securable to a surface of the foundation. Both the first and second members have a threaded bore therethrough, and are sized to have widths which are less than the diameter of the post. A threaded stud is threadably engagable with the threaded bores of the first and second members. For installation, the recess is formed in the lower surface of the post, the upper surface of the foundation, or both, so as to be sufficiently sized to receive the first and second members and the threaded stud.

a threaded stud threadably engagable with the first and second threaded bores of the first and second members;

whereby when the first member is secured to the lower surface of the post and the second member is secured to the surface of the foundation, the post is secured to the second member by being rotated so as to thread the first and second members toward each other, and whereby the fastening assembly is completely concealed within the recess between the post and the foundation.

2. A fastening assembly as recited in claim 1 further comprising:

means for securing the first member to the post so as to abut the upper surface of the first member against the lower surface of the post; and

means for securing the second member to the foundation so as to abut the lower surface of the second member against the surface of the foundation.

3. A fastening assembly as recited in claim 2 wherein the means for securing the first member to the post is intermediately located between a perimeter of the first member and the first threaded bore, and wherein the means for securing the second member to the foundation is intermediately located between a perimeter of the second member and the second threaded bore.

4. A fastening assembly as recited in claim 1 wherein the first threaded bore is centrally located in the first member and the second threaded bore is centrally located in the second member.

5. A fastening assembly as recited in claim 1 wherein the first and second members are annular-shaped disks.

6. A fastening assembly as recited in claim 1 wherein the first member has a bearing surface oppositely disposed from the upper surface of the first member, and wherein the second member has a bearing surface oppositely disposed from the lower surface of the second member, the bearing surface of the second member being slidably engagable with the bearing surface of the first member while the post is rotated relative to the foundation.

7. A newel post fastening assembly for anchoring a newel post to a floor such that the fastening assembly is received within a recess formed between a lower surface of the post and an upper surface of the floor, the fastening assembly comprising:

a first member having a first threaded bore therethrough, a perimeter whose width is less than the diameter of the newel post, and a thickness in a direction perpendicular to the width of the first member, the first member having an upper surface for abutting the lower surface of the newel post and a bearing surface oppositely disposed from the upper surface of the first member;

a second member having a second threaded bore therethrough, a perimeter whose width is less than the diameter of the newel post, and a thickness in a direction perpendicular to the width of the second member, the second member having a lower surface for abutting the upper surface of the floor and a bearing surface oppositely disposed from the lower surface of the second member, the bearing surface of the second member being slidably engagable with the bearing surface of the first member;

a threaded stud threadably engagable with the first and second threaded bores of the first and second members;

means for securing the first member to the newel post so as to abut the upper surface of the first member against the lower surface of the newel post; and

means for securing the second member to the floor so as to abut the lower surface of the second member against the upper surface of the floor;

whereby when the first member is secured to the lower surface of the newel post and the second member is secured to the upper surface of the floor, the post is threadably anchored to the floor by being rotated so as to thread the first and second members toward each other, and whereby the fastening assembly is completely concealed within the recess between the newel post and the floor.

8. A newel post fastening assembly as recited in claim 7 wherein the means for securing the first member to the newel post and the means for securing the second member to the floor comprise:

a first plurality of holes located intermediate the first threaded bore and the perimeter of the first member;

a second plurality of holes located intermediate the second threaded bore and the perimeter of the second member;

a first plurality of threaded fasteners individually engaged with the first plurality of holes for securing the first member to the lower surface of the newel post so as to abut the upper surface of the first member against the lower surface of the newel post; and

a second plurality of threaded fasteners individually engaged with the second plurality of holes for securing the second member to the floor so as to abut the lower surface of the second member against the upper surface of the floor.

9. A newel post fastening assembly as recited in claim 7 wherein the first threaded bore is centrally located in the first member and the second threaded bore is centrally located in the second member.

10. A newel post fastening assembly as recited in claim 7 wherein the first and second members are annular-shaped disks.

11. A newel post fastening assembly as recited in claim 7 wherein an axial length of the threaded stud is greater than the combined thicknesses of the first and second members.

12. A newel post fastening assembly as recited in claim 7 wherein the bearing surface of the first member and the bearing surface of the second member are both planar surfaces.

13. A method for anchoring a post to a foundation, the method comprising the steps of:

forming a recess so as to be located between the post and the foundation when the post is anchored to the foundation;

securing a first member to a lower surface of the post such that an upper surface of the first member abuts the lower surface of the post and such that an outer perimeter of the first member is circumscribed by the perimeter of the post, the first member having a first threaded bore therethrough;

securing a second member to a surface of the foundation such that a lower surface of the second member abuts the upper surface of the foundation and such that an outer perimeter of the second member will be circumscribed by the perimeter of the post once the post is anchored to the foundation, the second member having a second threaded bore therethrough; and

threadably engaging a threaded stud with one of the first and second threaded bores of the first and second members, respectively;

positioning the post relative to the foundation such that the first member, the second member and the threaded stud are axially aligned;

threadably securing the post to the foundation by rotating the post relative to the foundation such that the threaded stud is threadably engaged with the first and second threaded bores of the first and second members, respectively; and

threadably anchoring the post to the foundation by further rotating the post so as to thread the first and second members toward each other until the post abuts the foundation and the first and second members and the threaded stud are completely concealed within the recess between the post and the foundation.

14. A method as recited in claim 13 further comprising the step of forming the first and second members as annular-shaped disks.
