Abstract

A D-type screwing assembly for furniture contains a retaining member including a hole defined in the retaining member, with a plurality of ribs defined on two sides of the retaining member, and with a slot formed on a top end of the retaining member. A screw member includes at least two orifices defined on a head end of the screw member and a thread section formed on the screw member to screw with the hole of the retaining member. A rotary member includes at least two posts extending outwardly from a front end of the rotary member, with a number of the at least two posts corresponding to that of the at least two orifices of the screw member, so that the at least two posts of the rotary member are fitted into the at least two orifices of the screw member correspondingly.

Claims

1. A screwing assembly for furniture comprising:

a retaining member including an outer wall and a fastener defined in the retaining member, with the outer wall having generally circular cross sections having an axis, with a plurality of ribs defined on the retaining member, with each of the plurality of ribs being arcuate about the axis, with the plurality of ribs being axially spaced along the axis, and with a slot formed on the retaining member;

a screw member including at least two orifices defined on a head end of the screw member and a thread section formed on the screw member to screw with the fastener of the retaining member; and

a rotary member including at least two posts extending outwardly from a front end of the rotary member, with the at least two posts being spaced from each other, with a number of the at least two posts corresponding to that of the at least two orifices of the screw member, wherein the at least two posts of the rotary member are fitted into the at least two orifices of the screw member correspondingly.

2. The screwing assembly for furniture as claimed in claim 1, wherein a shape of each post of the rotary member is selected from a polygonal column and a circular column.

3. The screwing assembly for furniture as claimed in claim 1, wherein a shape of each orifice of the screw member corresponds to that of each post.

4. The screwing assembly for furniture as claimed in claim 1, wherein the fastener extends generally perpendicular to the axis, and with the slot extending radially relative to the axis.

5. The screwing assembly for furniture as claimed in claim 4, wherein the slot extends parallel to the fastener.

6. The screwing assembly for furniture as claimed in claim 5, wherein the plurality of ribs are circumferentially spaced.

7. The screwing assembly for furniture as claimed in claim 6, wherein the at least two posts comprises first, second and third posts, with the second post being intermediate and spaced from the first and third posts.

8. The screwing assembly for furniture as claimed in claim 7, wherein the second post is a polygonal column and the first and third posts are circular columns.

9. The screwing assembly for furniture as claimed in claim 7, wherein the second post has cross sections larger than cross sections of the first and second posts parallel to the cross sections of the second post.

10. The screwing assembly for furniture as claimed in claim 7, wherein the fastener comprises a hole extending through the retaining member.

11. The screwing assembly for furniture as claimed in claim 7, wherein the fastener comprises a threaded extension extending radially from the outer wall.

12. The screwing assembly for furniture as claimed in claim 1, wherein the fastener comprises a hole extending in the retaining member parallel to the axis.

13. The screwing assembly for furniture as claimed in claim 12, wherein the slot extends radially relative to the axis.

14. The screwing assembly for furniture as claimed in claim 13, wherein the at least two posts comprises first, second and third posts, with the second post being intermediate and spaced from the first and third posts.

15. The screwing assembly for furniture as claimed in claim 14, wherein the second post is a polygonal column and the first and third posts are circular columns.

16. The screwing assembly for furniture as claimed in claim 14, wherein the second post has cross sections larger than cross sections of the first and second posts parallel to the cross sections of the second post.

17. The screwing assembly for furniture as claimed in claim 1, wherein the at least two posts comprises first, second and third posts, with the second post being intermediate and spaced from the first and third posts.

18. The screwing assembly for furniture as claimed in claim 17, wherein the second post is a polygonal column and the first and third posts are circular columns.

19. The screwing assembly for furniture as claimed in claim 17, wherein the second post has cross sections larger than cross sections of the first and second posts parallel to the cross sections of the second post.

20. A screwing assembly for furniture comprising:

a retaining member including an outer wall and a fastener defined in the retaining member, with the outer wall having generally circular cross sections having an axis, with a plurality of ribs defined on the retaining member, with each of the plurality of ribs being arcuate about the axis, with the plurality of ribs being axially spaced along the axis, and with a slot formed on the retaining member;

a screw member including a cylindrical bore defined on a head member and a thread section to screw with the fastener of the retaining member, with the cylindrical bore located concentrically inward of the thread section; and

a rotary member including an acting end of circular cross sections for slideable receipt in the cylindrical bore, with the acting end including portions extending radially with respect to the acting end and interacting with corresponding portions of the cylindrical bore.
