Abstract

Finial end cap assemblies for telescoping curtain rods are disclosed. The finial assemblies include an outer finial cover and an inner finial base threadably mounted into each end of a curtain rod. A rotatable end pad is mounted on each finial base. The rods may include telescoping sections that are axially extendable from each other and lockable by a twisting motion. During installation on a support structure such as a window frame or shower stall, the finial cover, finial base and end of the curtain rod are fixed together by threaded engagement of the finial base with a threaded insert inside the end of the curtain rod, while the end pad is freely rotatable in order to maintain stationary contact with the support structure when the rod sections are twisted.

Claims

1. A curtain rod and finial assembly comprising:

a telescoping curtain rod having a first end and a second end; and

a first finial assembly mounted on the first end of the curtain rod comprising;

a finial base including a body, an annular base rim, a central through hole radially inside the annular base rim, a shoulder at an end of the body opposite from the annular base rim, and a threaded stud extending from the shoulder;

a finial cover surrounding the finial base and including a recess receiving the first end of the curtain rod; and

a rotatable end pad rotatably mounted adjacent the annular base rim and including a projection extending through the through hole of the finial base structured and arranged to retain the rotatable end pad on the finial base, wherein

the threaded stud of the finial base is threadingly secured to the first end of the curtain rod, and a bottom wall of the recess of the finial cover is located between the shoulder of the finial base and the first end of the curtain rod.

2. The curtain rod finial assembly of claim 1, wherein the first end of the curtain rod, the finial base, and the finial cover are fixed together and do not rotate with respect to each other during installation of the curtain rod and finial assembly on a support structure, and the rotatable end pad is freely rotatable with respect to the curtain rod, the finial base, and the finial cover.

3. The curtain rod finial assembly of claim 1, wherein the body of the finial base includes two opposing broad side surfaces connected by two opposing narrow side surfaces defining a generally rectangular cross section of the body.

4. The curtain rod finial assembly of claim 3, wherein the generally rectangular cross section of the body of the finial base has a width and a thickness, and the width is at least 2 times greater than the thickness.

5. The curtain rod finial assembly of claim 4, wherein a ratio of the width to the thickness is from 3:

1 to 8;

1.

6. The curtain rod finial assembly of claim 1, wherein the shoulder of the finial body extends in a radial extension direction perpendicular to an axial direction of the curtain rod a distance equal to or greater than an inner diameter of the curtain rod.

7. The curtain rod finial assembly of claim 6, wherein the shoulder has a thickness measured in a direction perpendicular to the radial extension direction of the shoulder and perpendicular to the axial direction of the curtain rod that is at least 3 times less than the radial extension distance of the shoulder.

8. The curtain rod finial assembly of claim 1, further comprising a threaded insert secured inside the first end of the curtain rod having a central threaded hole, and the threaded stud of the finial base is threadingly engaged with the central threaded hole of the threaded insert to thereby prevent relative rotation of the finial body and the finial cover in relation to the first end of the curtain rod during installation of the curtain rod and finial assembly on a support structure.

9. The curtain rod finial assembly of claim 1, wherein the rotatable end pad is fixedly mounted on a swivel bushing comprising an annular outer rim located radially outside the rotatable end pad and an annular retaining collar surrounding the projection of the rotatable end pad and extending through the central through hole of the finial base.

10. The curtain rod finial assembly of claim 1, further comprising a second finial assembly mounted on the second end of the curtain rod comprising:

an additional finial base including a body, an annular base rim, a central through hole radially inside the annular base rim, a shoulder at an end of the body opposite from the annular base rim, and a threaded stud extending from the shoulder,

an additional a finial cover surrounding the additional finial base and including a recess receiving the second end of the curtain rod; and

an additional a rotatable end pad rotatably mounted adjacent the annular base rim and including a projection extending through the through hole of the additional finial base structured and arranged to retain the rotatable end pad on the additional finial base, wherein

the threaded stud of the additional finial base is threadingly secured to the second end of the curtain rod, and a bottom wall of the recess of the additional finial cover is located between the shoulder of the additional finial base and the second end of the curtain rod.

11. The curtain rod finial assembly of claim 10, wherein the second end of the curtain rod, the additional finial base, and the additional finial cover are fixed together and do not rotate with respect to each other during installation of the curtain rod and additional finial assembly on a support structure, and the additional rotatable end pad is freely rotatable with respect to the curtain rod, the additional finial base, and the additional finial cover.

12. The curtain rod finial assembly of claim 10, wherein the body of the additional finial base includes two opposing broad side surfaces connected by two opposing narrow side surfaces defining a generally rectangular cross section of the additional finial body.

13. The curtain rod finial assembly of claim 12, wherein the generally rectangular cross section of the additional finial body of the additional finial base has a width and a thickness, and the width is at least 2 times greater than the thickness.

14. The curtain rod finial assembly of claim 13, wherein a ratio of the width to the thickness is from 3:

1 to 8;

1.

15. The curtain rod finial assembly of claim 10, wherein the shoulder of the additional finial body extends in a radial extension direction perpendicular to an axial direction of the curtain rod a distance equal to or greater than an inner diameter of the curtain rod.

16. The curtain rod finial assembly of claim 15, wherein the shoulder of the additional finial body has a thickness measured in a direction perpendicular to the radial extension direction of the shoulder and perpendicular to the axial direction of the curtain rod that is at least 3 times less than the radial extension distance of the shoulder.

17. The curtain rod finial assembly of claim 10, further comprising a threaded insert secured inside the second end of the curtain rod having a central threaded hole, and the threaded stud of the additional finial base is threadingly engaged with the central threaded hole of the threaded insert to thereby prevent relative rotation of the additional finial body and the additional finial cover in relation to the second end of the curtain rod during installation of the curtain rod and additional finial assembly on a support structure.

18. The curtain rod finial assembly of claim 10, wherein the additional rotatable end pad is fixedly mounted on a swivel bushing comprising an annular outer rim located radially outside the additional rotatable end pad and an annular retaining collar surrounding the projection of the additional rotatable end pad and extending through the central through hole of the additional finial base.

19. The curtain rod finial assembly of claim 10, wherein the finial base secured to the first end of the curtain rod and the additional finial base secured to the second end of the curtain rod have the same shape and size.

20. A finial assembly for mounting on an end of a curtain rod comprising:

a finial base including a body, an annular base rim, a central through hole radially inside the annular base rim, a shoulder at an end of the body opposite from the annular base rim, and a threaded stud extending from the shoulder,

a finial cover surrounding the finial base and including a recess structured and arranged to receive the end of the curtain rod; and

a rotatable end pad rotatably mounted adjacent the annular base rim and including a projection extending through the through hole of the finial base structured and arranged to retain the rotatable end pad on the finial base.
