Abstract

A device for facilitating the insertion of a beach umbrella in the sand includes a shaft formed as a helix about an axis of rotation with a handle attached to one end thereof. The curvature of the helix defines a major diameter and the shaft of the device is at least a quarter the size of the major diameter. The shaft is manually inserted in the sand and then withdrawn thereby forming a hole for the insertion of the beach umbrella support shaft.

Claims

1. A device for facilitating the upright placement of a beach umbrella in sand, the beach umbrella including a retractable canopy and a support shaft, said device comprising:

a generally longitudinally extending shaft having a first end portion and a second end portion, said shaft being formed as a helix about an axis of rotation, said helix defining a major diameter bounded by the outermost extent of the helical curvature, said diameter remaining substantially constant throughout the length of the helix, said first and second end portions being formed with a diameter that is a predetermined amount smaller than the value of said major diameter, said first end portion being configured for insertion in sand; and

handle means disposed at said second end portion for manually causing rotation of said helical shaft for driving said shaft into the sand to pack the sand outwardly of the helical shaft, and for the manual withdrawal of said shaft thereby forming a hole in the sand for insertion of the beach umbrella support shaft thereinto.

2. A device for facilitating the upright placement of a beach umbrella in sand according to claim 1 wherein said helical shaft is formed with a diameter that is at least a quarter the size of said major diameter.

3. A device for facilitating the upright placement of a beach umbrella in sand according to claim 1 wherein said major diameter generally conforms to the diameter of the beach umbrella support shaft.

4. A device for facilitating the upright placement of a beach umbrella in sand according to claim 1 wherein said handle means is formed as a rod mounted to said second end portion in a generally perpendicular relationship therewith with a portion of said rod extending outwardly away from said helical shaft.

5. A device for facilitating the upright placement of a beach umbrella in sand according to claim 4 wherein said handle means includes a hand grip.

6. A device for facilitating the upright placement of a beach umbrella in sand according to claim 1 wherein said shaft is formed in a mold from a thermoplastic material.

7. In combination, a beach umbrella having a canopy mounted to a support shaft and a device for facilitating the upright placement of said beach umbrella in sand comprising:

a generally longitudinally extending shaft having a first end portion and a second end portion, said shaft being formed as a helix about an axis of rotation, said helix defining a major diameter bounded by the outermost extent of the helical curvature, said diameter remaining substantially constant throughout the length of the helix, said first and second end portions being formed with a diameter that is a predetermined amount smaller than the value of said major diameter, said first end portion being configured for insertion in sand; and

handle means disposed at said second end portion for manually causing rotation of said helical shaft for driving said shaft into the sand to pack the sand outwardly of the helical shaft, and for the manual withdrawal of said shaft thereby forming a hole in the sand for insertion of said beach umbrella support shaft thereinto.

8. A device for facilitating the upright placement of a beach umbrella in sand according to claim 7 wherein said helical shaft is formed with a diameter that is at least a quarter the size of said major diameter.

9. A device for facilitating the upright placement of a beach umbrella in sand according to claim 7 wherein said major diameter generally conforms to the diameter of said beach umbrella support shaft.

10. A device for facilitating the upright placement of a beach umbrella in sand according to claim 7 wherein said handle means is formed as a rod mounted to said second end portion in a generally perpendicular relationship therewith with a portion of said rod extending outwardly away from said helical shaft.

11. A device for facilitating the upright placement of a beach umbrella in sand according to claim 10 wherein said handle means includes a hand grip.
