Abstract

A mount holding a vertical rod with a ball at its top positioned in a ball joint opening of a housing having an umbrella holder within a bore extending from the ball joint opening at the top of the housing. When the umbrella holder is slightly raised so that the ball is no longer being forced against the ball joint opening, the housing may be pivoted about the ball. A nut on the vertical rod supports the housing which has a conical bottom extending below the ball so that the housing is tilted by adjusting the height of the nut. In another embodiment a slot at the housing bottom allows the housing to be tilted past the vertical rod to a horizontal position. In another embodiment the ball is locked into position by means of a cam and plunger.

Claims

1. An adjustable ball joint pole mounting, comprising:

a first sleeve having a bore in the upper end thereof for holding a pole and threaded at the lower end thereof;

a housing having a threaded sleeve at the upper end thereof for threadedly engaging the lower end of said first sleeve, a ball joint opening extending from the threaded sleeve at the lower end of said housing, and a conical shaped bottom;

a ball positioned within the ball joint opening of said housing for pivoting and tilting said housing, said housing becoming locked at the desired angle when the lower end of said first sleeve is screwed into said ball joint opening for preventing movement between said housing and said ball;

a threaded rod havIng said ball secured to the top thereof;

a mount having a vertical threaded bore for holding said threaded rod in a vertical position; and

a nut on said threaded rod supporting the conical shaped bottom of said housing, the conical shaped bottom of said housing extending below said ball for tilting said housing at a desired angle by adjusting the height of said nut.

2. An adjustable ball joint pole mounting as recited in claim 8, wherein:

said mount includes a stationary plate including a raised cylindrical portion in the center thereof containing said vertical threaded bore and a flat base for securing said mount to a horizontal surface.

3. An adjustable ball joint pole mounting as recited in claim 8, wherein:

said mount includes a sleeve fitted over and secured to a vertical post, said sleeve having a top horizontal surface containing said vertical threaded bore.

4. An adjustable ball joint pole mounting as recited in claim 8, wherein:

said mount includes a U-shaped clamp comprising a lower horizontal leg threadedly holding a clamp screw for manual adjustment, clamping and securing said mount to a horizontal surface, and an upper horizontal leg containing said vertical threaded bore.

5. An adjustable ball joint pole mounting as recited in claim 8, wherein:

said housing has a slot extending upwards from the conical shaped bottom and terminating above the lower end of the ball joint opening, the width of the slot being greater than that of said threaded rod for tilting said housing past said threaded rod to a horizontal position.

6. An adjustable ball joint pole mounting, comprising:

a housing having a sleeve at the upper end thereof for holding a pole, a ball joint opening at the lower end of said housing, and a conical-shaped shaped bottom;

a ball positioned within the ball joint opening of said housing for pivoting and tilting said housing;

locking means within said housing;

a threaded rod having said ball secured to the top thereof;

a mount having a vertical threaded bore for holding said threaded rod in a vertical position; and

a nut on said threaded rod supporting the conical shaped bottom of said housing, the conical shaped bottom of said housing extending below said ball for tilting said housing at a desired angle by adjusting the height of said nut.

7. The adjustable ball joint pole mounting of claim 6, wherein said locking means includes a first sleeve having a bore in the upper end thereof for holding a pole and threaded at the lower end thereof for threaded engagement with said housing sleeve, said housing becoming locked at the desired angle when the lower end of said first sleeve is screwed into said ball joint opening for preventing movement between said housing and said ball.

8. The adjustable ball joint pole mounting of claim 6, wherein said locking means includes:

a plunger within the sleeve of said housing resting on the top surface of said ball;

a cam positioned within the sleeve of said housing above said plunger; and

a handle pivotally mounted in the sleeve of said housing and secured to said cam for rotation of said cam which presses down said plunger on the top surface of said ball forcing said ball against the side of the ball joint opening of said housing for preventing movement between said housing and said ball.
