Beach umbrella hole digging device

Abstract

A beach umbrella hole digging device including a tubular shaft with a pair of handles and a plunger rod that passes through the shaft and out the top. The handles help push and rotate the device into the sand. Once removed, the plunger rod can push out the sand that was inside the tubular shaft. Regular intervals are marked on the outside of the tubular shaft to show a user how deep the hole is and allow for a precise depth. By creating a hole that is the perfect diameter and depth for an umbrella pole, the user can securely set up his or her umbrella with minimal effort and time required. Furthermore, the construction of the present beach umbrella hole digging device is simple and allows for each of the components to press fit together. The device can look like the body and head of an animal.

DETAILED DESCRIPTION OF THE DRAWINGS

(8) With reference now to the drawings, and in particular FIGS. 1 through 7 thereof, an example of the present beach umbrella hole digging device employing the principles and concepts of the present beach umbrella hole digging device and generally designated by the reference number 10 will be described.

(9) Referring to FIGS. 1 through 7 the present beach umbrella hole digging device 10 is illustrated. The beach umbrella hole digging device 10 includes a tubular shaft 20 having an exterior 22, an interior 24, a central axis 26, a length 28, an outer diameter 30, and an inner diameter 32. A plurality of evenly spaced horizontal demarcations 34 is disposed on the exterior of the tubular shaft.

(10) A tubular T joint 40 has an outer diameter 42 and an inner diameter 44. The outer diameter of the tubular T joint 42 is greater than the outer diameter of the tubular shaft 30, and the inner diameter of the tubular T joint 44 substantially conforms to the outer diameter of the tubular shaft 30. Each of the outer diameter of the tubular shaft 30 and the inner diameter of the tubular T joint 44 is configured such that the tubular T joint 40 can receive the tubular shaft 20 as a press fit.

(11) A pair of tubular handles 48 has a capped end 50, an open end 52, a thin section 54, and a thick section 55.
