Abstract

A furniture member rocker spring assembly includes first and second bracket members arranged in mirror image configuration. First and second springs are positioned between and in direct contact with each of the first and second bracket members. A restrictor bolt assembly is positioned between the first and second springs. The restrictor bolt assembly includes at least one sleeve member received in an aperture of the first and second bracket members. The sleeve member is in sliding contact with the first and second bracket members. A fastener extends through a sleeve bore of each of the first and second sleeve members. The fastener retains the first sleeve member in contact with the second sleeve member.

First claim

What is claimed is:

1. A furniture member rocker spring assembly, comprising:
first and second bracket members, the first and second bracket members being movable relative to each other;
at least one spring extending between and directly contacting the first and second bracket members, the at least one spring defining a minimum spacing of the first and second bracket members when the at least one spring is fully compressed; and
a restrictor bolt assembly extending through each of the first and second bracket members, the restrictor bolt assembly including:
at least one sleeve member received in an aperture of the first and second bracket members such that the at least one sleeve member is in sliding contact with the first and second bracket members, the at least one sleeve member defining a restrictor bolt working length that is greater than the minimum spacing of the first and second bracket members; and
a fastener received through a sleeve bore of the at least one sleeve member.

2. The furniture member rocker spring assembly of claim 1 , wherein the at least one sleeve member includes first and second sleeve members each having a sleeve bore slidably receiving the fastener.

3. The furniture member rocker spring assembly of claim 2 , wherein each of the first and second sleeve members are a polymeric material.

4. The furniture member rocker spring assembly of claim 3 , wherein each of the first and second sleeve members includes a flared end having a diameter larger than a diameter of the aperture of the first and second bracket members.

5. The furniture member rocker spring assembly of claim 2 , wherein:
each of the first and second sleeve members includes a flared end having a diameter larger than a diameter of the aperture of the first and second bracket members; and
the flared ends are individually positioned at opposite outer facing surfaces of the first and second bracket members, the flared ends both contacting the first and second bracket members at a maximum extended position of the first and second bracket members.

6. The furniture member rocker spring assembly of claim 2 , wherein:
each of the first and second sleeve members includes a flared end having a diameter larger than a diameter of the aperture of the first and second bracket members, the flared ends operably contacting one of the first and second bracket members to limit a maximum displacement between the first bracket member and the second bracket member; and
the fastener includes a fastener head on a first end and a stub fastener engaged on a second end, the fastener head and the stub fastener each operably contacting one of the flared ends to couple the first and second sleeve members.

7. The furniture member rocker spring assembly of claim 1 , wherein the first and second bracket members are substantially identical and arranged in mirror image configuration with respect to each other.

8. The furniture member rocker spring assembly of claim 1 , wherein the fastener includes a fastener head on a first end and a stub fastener connected to a second end, the fastener head and the stub fastener each having a diameter larger than a diameter of the aperture of the first and second bracket members, the fastener head and the stub fastener thereby limiting a maximum displacement between the first bracket member and the second bracket member.

9. The furniture member rocker spring assembly of claim 1 , wherein the at least one sleeve member is a polymeric material preventing contact between the fastener and the first and second bracket members.

10. The furniture member rocker spring assembly of claim 1 , wherein the at least one sleeve member extends past both of the first and second bracket members and prevents the fastener from contacting either of the first or second bracket members in any position of the first and second bracket members.

11. A furniture member rocker spring assembly, comprising:
first and second bracket members arranged in mirror image configuration, the first and second bracket members being movable relative to each other;
at least one spring extending between and in direct contact with each of the first and second bracket members, the at least one spring defining a minimum spacing of the first and second bracket members when the at least one spring is fully compressed; and
a restrictor bolt assembly extending between the first and second bracket members, the restrictor bolt assembly including:
first and second sleeve members each received in an aperture of the first and second bracket members, the first and second sleeve members in sliding contact with the first and second bracket members; and
a fastener extending through a sleeve bore of each of the first and second sleeve members, the fastener retaining the first sleeve member in contact with the second sleeve member at a sleeve contact joint, the first and second sleeve members defining a restrictor bolt working length that is greater than the minimum spacing of the first and second bracket members.

12. The furniture member rocker spring assembly of claim 11 , wherein the first and second sleeve members are aligned coaxially to each other.

13. The furniture member rocker spring assembly of claim 11 , wherein each of the first and second sleeve members are a polymeric material.

14. The furniture member rocker spring assembly of claim 11 , wherein each of the first and second sleeve members includes a flared end having a diameter larger than a diameter of the aperture of the first and second bracket members, the flared end preventing the first and second sleeves from sliding through the aperture of either of the first or second bracket members.

15. The furniture member rocker spring assembly of claim 11 , wherein the at least one spring includes a first spring and a second spring, the first spring and the second spring are spaced apart from one another, and a spacing between the restrictor bolt assembly and the first spring is equal to a spacing between the restrictor bolt assembly and the second spring.

16. The furniture member rocker spring assembly of claim 11 , wherein a diameter of both of the first and second sleeves is less than a diameter of the aperture of the first and second bracket members to permit sliding motion of the first and second sleeves in the aperture of the first and second bracket members.
