Abstract
A tool for a power drill allows fast and convenient loading and unloading of a screw bit, drill bit, or other implement. The user preferably loads the tool with the necessary implements which are then carried with the tool. Each received implement is movable from a storage position to an in use position in drive engagement with the power drill or power screwdriver. The desired implements can rapidly be changed from one to the other, while the implements are retained on the tool.
Claims19
A tool for receipt in a drill chuck, said tool comprising an elongate drive shaft having an implement receiving socket at one end thereof and a drive end for engaging a drill chuck at an opposite end, said tool further including an implement receiving collar about an intermediate portion of said drive shaft which allows rotation of said drive shaft without rotation of said implement receiving collar, said implement receiving collar having at least 3 implement carriers with each carrier at least pivotally mounted to said collar about a pivot axis offset and perpendicular to said elongate drive shaft for movement between a storage position to an in use position which aligns an implement received in said implement carrier with said implement receiving socket of said drive shaft for receipt therein, each implement receiving carrier in said storage position locating an implement received therein to one side of said drive shaft and each implement receiving carrier in said in use position allowing rotation of an implement received therein and in engagement with said drive shaft socket to rotate with said drive shaft without rotation of said implement receiving carrier, said tool further including a spring biased latch associated with said implement receiving socket for releasably retaining an implement in said drive socket;
- said spring biased latch including a coil spring having a segment thereof displaceable into and out of said implement receiving socket to form a releasable latch with a retaining groove of an implement received in a drive position within said drive socket;
- and wherein said spring biased latch is a two position latch, said two position latch having a first position retaining an implement received in said drive socket in a drive position and a second position where an implement is held in said drive socket in a manner to allow hand withdrawal of said implement from said drive socket.
A tool for receipt in a drill chuck, said tool comprising an elongate drive shaft having an implement receiving socket at one end thereof and a drive end for engaging a drill chuck at an opposite end, said tool further including an implement receiving collar about an intermediate portion of said drive shaft which allows rotation of said drive shaft without rotation of said implement receiving collar, said implement receiving collar having at least 3 implement carriers with each carrier having an L shape configuration defined by a base arm and an implement receiving arm at one end of said base arm, said base arm at an end thereof opposite said implement receiving arm having a pivot and slide securement to said collar;
- each pivot and slide securement including a pivot axis of said carrier offset and perpendicular to said elongate drive shaft;
- said collar including a series of elongate slot recesses extending parallel to said drive shaft with each elongate slot recess partially receiving the base arm of the respective carrier;
- said pivot axis of each carrier being slidable along the respective slot recess of the collar and movable along the slot recess between a storage position of said carrier at one end of said slot recess and a spaced in use position towards an end of said slot recess slot opposite said one end of said slot recess;
- each carrier when moved from said storage position to said in use position pivoting about said pivot axis and sliding along said slot recess to align an implement received in said carrier with said implement receiving socket of said drive shaft with said aligned implement being received in said drive socket by sliding movement of said pivot axis of said carrier in said slot recess to said in use position;
- each implement receiving carrier in said storage position locating an implement received therein to one side of said drive shaft and each implement receiving carrier in said in use position allowing rotation of an implement received therein and in engagement with said drive shaft socket to rotate with said drive shaft without rotation of said implement receiving carrier.
In a power tool having a motor driven elozigate drive shaft, the improvement including an implement receiving socket at one end of the drive shaft and an implement receiving collar bearingly supported on an intermediate portion of said drive shaft allowing rotation of said drive shaft without rotation of said implement receiving collar;
- said implement receiving collar having at least 3 implement carriers with each carrier having an L shape configuration defined by a base arm and an implement receiving arm at one end of said base arm, said base arm at an end thereof opposite said implement receiving arm having a pivot and slide securement to said collar;
- each pivot and slide securement including a pivot axis of said carrier offset and perpendicular to said elongate drive shaft;
- said collar including a series of elongate slot recesses extending parallel to said drive shaft with, each elongate slot recess partially receiving the base arm of the respective carrier;
- said pivot axis of each carrier being slidable along the respective slot recess of the collar and movable along the slot recess between a storage position of said carrier at one end of said slot recess and a spaced in use position towards an end of said slot recess slot opposite said one end of said slot recess;
- each carrier when moved from said storage position to said in use position pivoting about said pivot axis and sliding along said slot recess to align an implement received in said carrier with said implement receiving socket of said drive shaft with said aligned implement being received in said drive socket by sliding movement of said pivot axis of said carrier in said slot recess to said in use position;
- each implement receiving carrier in said storage position locating an implement received therein to one side of said drive shaft and each implement receiving carrier in said in use position allowing rotation of an implement received therein and in engagement with said drive shaft socket to rotate with said drive shaft without rotation of said implement receiving carrier.
