Abstract

A fastening apparatus includes a reducer bolt and a complimentary female threaded element. The reducer bolt has an elongate threaded shank for inserting into the complementary female threaded element. The reducer bolt has a collar defining a threaded female opening. The collar is carried concentrically on the shank and has a diameter greater than the shank so that the collar contacts the complementary female threaded element to prevent further insertion of the shank into the female threaded element. A head is carried concentrically on the collar, and has an aperture communicating with the collar opening to receive a complementary male threaded member which mates with the threaded female opening of the collar. The head includes an engagement mechanism for receiving a complementary tool, such as a wrench, so that engagement between the shank and the complementary female threaded element is adjustable by turning the head with the tool.

Claims

1. A fastening apparatus comprising:

(a) an elongate threaded shank for being inserted into a complementary female threaded element;

(b) a collar concentrically provided on the shank, the collar defining a threaded female opening and having first and second ends, the first end proximate the shank and having a diameter greater than the shank for contacting the complementary female threaded element and preventing further insertion of the shank into the female threaded element;

(c) a head concentrically provided on the collar proximate the second end, the head having an aperture in communication with the collar opening for receiving a complementary male threaded member for mating with the threaded female opening of the collar; and

(d) wherein the head includes an engagement mechanism for receiving a tool whereby engagement between the shank and the complementary female threaded element is adjustable by turning the head with the complementary tool.

2. A fastening apparatus according to claim 1, wherein the engagement mechanism comprises a hexagonal indentation formed in the head, and the tool comprises an Allen wrench.

3. A fastening apparatus according to claim 1, wherein the engagement mechanism comprises wrench flats formed in the head, and the tool comprises a wrench.

4. A fastening apparatus according to claim 1, wherein the complementary female threaded element comprises a body defining a cavity having threads therein, and a cap having a diameter greater than the body.

5. A fastening apparatus according to claim 1, wherein the complementary female threaded element comprises a T-nut.

21. A fastening apparatus according to claim 1, wherein the aperture in the head has a hexagonal shape having an area greater than an area defined by the threaded female opening of the collar whereby an Allen wrench can engage the head aperture.

6. A fastening assembly for connecting a plurality of objects comprising:

(a) a first fastener comprising a body defining a cavity having threads therein; and

(b) a second fastener comprising;

(i) an elongate threaded shank adapted for being inserted into the cavity of the first fastener to engage the threads of the cavity therein,

(ii) a collar concentrically provided on the shank, the collar defining a threaded female opening and having first and second ends, the first end proximate the shank and having a diameter approximately equal to the body of the first fastener whereby the collar contacts the body of the first fastener and prevents further insertion of the shank into the cavity of the first fastener, and

(iii) a head concentrically provided on the collar proximate the second end, the head having an aperture in communication with the collar opening for receiving a complementary male threaded member for mating with the threaded female opening of the collar, and

(iv) wherein the head includes an engagement mechanism for receiving a tool whereby engagement between the first fastener and the second fastener is adjustable by turning the head of the second fastener with the tool.

7. A fastening assembly according to claim 6, wherein the engagement mechanism comprises a hexagonal indentation formed in the head, and the tool comprises an Allen wrench.

8. A fastening assembly according to claim 6, wherein the engagement mechanism comprises wrench flats formed in the head, and the tool comprises a wrench.

9. A fastening assembly according to claim 6, wherein the first fastener further comprises a cap having a diameter greater than the body and at least one bore therein.

10. A fastening assembly according to claim 6, wherein the first fastener and the second fastener are adapted for connecting components of a furniture piece.

11. A fastening assembly according to claim 6, wherein the second fastener is positioned within a first object, and the complementary male threaded member is positioned within a second object, whereby mating of the complementary male threaded member with the female threads of the second fastener connects the first and second objects.

12. A fastening assembly according to claim 11, wherein the first and second objects are components of a furniture piece.

22. A fastening apparatus according to claim 6, wherein the aperture in the head has a hexagonal shape having an area greater than an area defined by the threaded female opening of the collar whereby an Allen wrench can engage the head aperture.

23. A fastening apparatus according to claim 6, wherein the first fastener comprises a T-nut.

13. A method for connecting a plurality of objects comprising the steps of:

(a) providing a first fastener comprising a body defining a cavity having threads therein;

(b) positioning the first fastener within a first object;

(c) providing a second fastener comprising;

(i) an elongate threaded shank adapted for being inserted into the cavity of the first fastener and mating with the threads therein,

(ii) a collar defining a threaded female opening, the collar carried concentrically on the shank and having first and second ends, the first end proximate the shank and having a diameter approximately equal to the body of the first fastener whereby the collar contacts the body and prevents further insertion of the shank into the cavity of the first fastener; and

(iii) a head carried concentrically on the collar proximate the second end and having an aperture in communication with the collar opening for receiving a complementary male threaded member for mating with the threaded female opening of the collar, and wherein the head includes an engagement mechanism for receiving a tool; and

(d) inserting the shank into the cavity of the first fastener to engage the threads therein, whereby the first fastener is connected to the second fastener.

14. The method of claim 13, further comprising the step of tightening the connection between the first fastener and the second fastener by turning the head of the second fastener clockwise with the tool.

15. The method of claim 14, further comprising the step of releasing the connection between the first fastener and the second fastener by turning the head of the second fastener counterclockwise with the tool.

16. The method of claim 13, further comprising the steps of:

(a) positioning the complementary male threaded member in a second object; and

(b) inserting the complementary male threaded member into the threaded female opening of the second fastener to engage the second fastener and connect the first and second objects.

17. The method of claim 13, wherein the step of positioning the first fastener within a first object comprises positioning the first fastener within a first component of a furniture piece.

18. The method of claim 17, wherein the step of positioning the complementary male threaded member within a second object comprises positioning the male threaded member within a second component of the furniture piece, whereby the first and second components of the furniture piece are connected.

19. The method of claim 13, further comprising the step of positioning the second fastener within a second object, whereby the first and second objects are connected by engagement of the first fastener and the second fastener.

20. The method of claim 19, further comprising the steps of:

(a) positioning the complementary male threaded member in a third object; and

(b) inserting the complementary male threaded member into the threaded female opening of the second fastener to engage the second fastener and connect the second and third objects.
