Apparatus and method for preparing a surface
Embodiments of the invention provide an apparatus for preparing a surface that includes an elongated handle and a head portion removably securable to the elongated handle via a pivot joint, the head portion being adapted to receive a surface preparation material and being capable of pivotal movement relative to the elongated handle. The apparatus is configured to allow the elongated handle to remain substantially perpendicular to the head portion without any external support.
1. A surface preparation apparatus comprising:
a head portion having a base configured to removably receive a surface preparation material; and
a spherical handle located on and fixed to the base, the spherical handle being sized for ergonomic gripping by a human hand;
wherein the spherical handle is dimensioned and configured to pivotally and selectively mate with a socket on a distal end of an elongated handle via a frictional fit such that a user may prepare a surface by gripping the spherical handle, or, if attached, the elongated handle; and
wherein the frictional fit of the spherical handle and socket allows the elongated handle to be rotated about the spherical handle during use and to be resiliently maintained in a fixed position relative to the head portion when not in use.
2. The apparatus of claim 1 wherein the spherical handle and socket are pivotally interconnected via a snap or press fit.
3. The apparatus of claim 1 wherein the base includes plurality of slots that are configured to removably secure a sheet of surface preparation material to the head portion.
4. The apparatus of claim 3 wherein at least one of the slots includes an aperture configured to allow a user to urge a portion of the sheet into the slot.
5. The apparatus of claim 1 wherein the head portion is flexible such that it may be used to prepare a curved surface.
6. The apparatus of claim 1 , wherein:
the ball has a diameter between about 2 inches and about 4 inches.
7. An apparatus for preparing a surface comprising:
an elongated handle having a socket located on a distal end of the elongated handle;
a head portion having a ball fixed to the head portion, the head portion being adapted to receive a surface preparation material, the ball having a diameter of between about 2 inches and about 4 inches;
wherein the socket is configured to removably receive the ball to removably secure the head portion to the elongated handle; and
wherein the ball and the socket are held together by a frictional fit which allows the elongated handle to be freely rotated with respect to the head portion during use, and the elongated handle to remain substantially perpendicular to the head portion without any external support when not in use; and
wherein the apparatus allows a user to prepare a surface by grasping the elongated handle when it is attached to the head portion, and to prepare a surface by grasping the ball on the head portion with a power grip when the elongated handle is detached from the head portion.
8. An apparatus for preparing a surface comprising:
an elongated handle having a socket located on a distal end of the elongated handle;
a head portion having a ball fixed to the head portion the head portion being adapted to receive a surface preparation material;
wherein the socket is configured to removably receive the ball to removably secure the head portion to the elongated handle; and
wherein the ball is configured to form an ergonomic handgrip when the elongated handle is disconnected from the head portion, and is sized to allow a user to grasp the ball with a power grip to prepare a surface with the head portion, and wherein:
the ball and the socket are held together by a frictional fit which allows the elongated handle to be rotated with respect to the head portion during use, and the elongated handle to remain substantially perpendicular to the head portion without any external support when not in use.
9. The apparatus of claim 8 wherein the ball and socket are pivotally interconnected via a snap or press fit.
10. The apparatus of claim 8 wherein the head portion includes a plurality of slots configured to removably secure a surface preparation material to the head portion.
11. The apparatus of claim 8 wherein at least one of the slots includes an aperture configured to allow a user to urge a portion of the material into the slot.
12. The apparatus of claim 8 wherein the head portion is flexible such that it may be used to prepare a curved surface.
13. The apparatus of claim 8 wherein the handle is adjustable in length.
