Handle system for finishing tool
View Patent ↗The present disclosure describes a handle system for use with finishing tools utilized to finish wallboard joints. A finishing tool may be connected to the handle system and moved relative to a wallboard joint to appropriately apply mastic over the joint. In one embodiment, the handle system includes an elongate handle body having a tear drop cross-sectional shape. The shape enables the handle body to fit ergonomically within a user's hand and improves the user's ability to resist torque tending to cause the handle body to twist and a connected finishing tool to come out of contact with wallboard during use. The handle system further includes a pivoting connector assembly that permits a connected finishing tool to rotate relative to the handle body and that has a unique pivot pin that allows mastic to flow through the handle body, through the pivoting connector assembly, and into the connected finishing tool.
1. A handle system for finishing tools used to finish wallboard, said handle system comprising:
an elongate handle body that guides mastic therethrough and has a cross-sectional shape where grasped during use, the cross sectional shape corresponding substantially to the shape of a tear drop; and
a pivoting connector assembly pivotably connected to said elongate handle body for connection to a finishing tool, said pivoting connector assembly defining an internal path therethrough in fluid communication with said elongate handle body and with the connected finishing tool for allowing the mastic to flow from said elongate handle body to the connected finishing tool.
2. The handle system of claim 1 , wherein said elongate handle body defines a first channel therein for movably receiving a brake linkage for controlling pivoting of said pivoting connector assembly.
3. The handle system of claim 2 , wherein said elongate handle body has a first end and a second end distant therefrom, and said elongate handle body further defines a second channel through which the mastic to flows within said elongate handle body between said first end and said second end of said elongate handle body.
4. The handle system of claim 1 , wherein said pivoting connector assembly includes a first portion connected in a stationary relationship to said elongate handle body and a second portion pivotally connected to said first portion.
5. The handle system of claim 4 , wherein said first portion of said pivoting connector assembly defines a first channel therein for allowing the mastic to flow therethrough and said second portion of said pivoting connector assembly defines a second channel therein for allowing the mastic to flow therethrough, and wherein said pivoting connector assembly further includes a pivot pin for enabling relative rotary motion between said first portion and said second portion of said pivoting connector and for allowing the mastic to flow between said first channel and said second channel.
6. The handle system of claim 1 , wherein said pivoting connector assembly defines a pair of bores therein and includes a pair of fasteners coaxially aligned respectively with said pair of bores for respectively receiving a cooperative pair of mounting fasteners of a finishing tool and registering the finishing tool in proper orientation relative to said pivoting connector assembly.
7. A handle system for finishing tools used to finish wallboard, said handle system comprising:
a brake assembly for controlling the position of a finishing tool, said brake assembly including a brake actuator for receiving user input and a brake linkage operative with said brake actuator, said brake linkage controlling pivoting of a connected finishing tool relative to said elongate handle body in response to user input;
an elongate handle body defining a first channel therein for movably receiving said brake linkage therein and a second channel therein for allowing mastic to flow within said elongate handle body; and
a pivoting connector assembly pivotably secured to said elongate handle body for connection to a finishing tool, said pivoting connector assembly defining an internal fluid communication path therethrough in fluid communication with said second channel of said elongate handle body and with a connected finishing tool, the internal fluid communication path allowing the mastic to flow from said elongate handle body and into the connected finishing tool.
8. The handle system of claim 7 , wherein said elongate handle body has a substantially tear drop cross-sectional shape.
9. The handle system of claim 7 , wherein said elongate handle body has a substantially oval cross-sectional shape.
10. The handle system of claim 7 , wherein said elongate handle body has a substantially rectangular cross-sectional shape having radiused corners.
11. The handle system of claim 7 , wherein said elongate handle body has a substantially triangular cross-sectional shape having radiused vertices.
12. The handle system of claim 7 , wherein said brake linkage comprises a band.
13. The handle system of claim 7 , wherein said brake linkage comprises a cable.
14. The handle system of claim 7 , wherein said brake linkage comprises a rod.
15. The handle system of claim 7 , wherein said brake assembly further includes a brake disk configured to move in unison with the connected finishing tool and a member adapted to engage and disengage said brake disk in response to user input to control movement of said brake disk and the connected finishing tool.
16. The handle system of claim 3 , wherein the elongate handle includes a first end having a first opening and a second opening and a second end having a first opening and a second opening, the first channel extending between the first opening in the first end and the first opening in the second end, the second channel extending between the second opening in the first end and the second opening in the second end.
17. The handle system of claim 7 , wherein the elongate handle includes a first end having a first opening and a second opening and a second end having a first opening and a second opening, the first channel extending between the first opening in the first end and the first opening in the second end, the second channel extending between the second opening in the first end and the second opening in the second end.
