Embodiment Construction

[0022] Any suitable form of hand-held tool 10 is shown in Figures 1 to 5f, such as a power drill as shown. Although a power drill is shown in the drawings, it is understood that hand tool 10 may be implemented in many other forms, and thus the invention is not limited to the particular embodiment shown in the drawings.

[0023] Especially at Figure 1a and 1b 2, it can be seen that the hand-held tool 10 is configured as a drill, which has a main body housing 12 with a pistol grip portion 14, and the user of the hand-held tool 10 (hereinafter referred to as "drill 10") (not referred to as "drill 10") shown) can be comfortably held with one hand. A speed control slider or switch 16 allows the speed of the drill 10 to be varied to suit different materials (not shown) to be drilled. The pistol grip portion 14 has an enlarged base 18 to house a rechargeable battery (not shown) in the drill 10 to power it. The two trigger switches 20, 22 are respectively the power ON / OFF switch (...

Abstract

A tool (10) including a plurality of bit holders (26, 28) interchangeable with one another at a position of use in front of the tool (10). The bit holders (26, 28) being mounted at arcuately-spaced positions on a turret (24) rotatable around an axis (50) which is set at an angle to an axis (30) of rotation of a drive shaft (42). The drive shaft (42) being reciprocal between first and second axially- spaced locations at which, respectively, the drive shaft (42) is engaged and disengaged from a bit holder (26, 28) at the position of use. The positioning of the drive shaft (42) being such that at the second location a drive connection between the drive shaft (42) and the turret (24) is established so that subsequent operation of the drive shaft (42) rotates the turret (24) and interchanges the positions of the bit holders (26, 28) at the position of use. The drive shaft (42) being adapted to return to its first location and restore the drive connection with a new bit holder (26, 28) at the position of use after the turret (24) has been rotated.

Description

technical field [0001] The present invention generally relates to a hand-held tool having a drive shaft and rotatable drill holder that can be selectively brought to a position of use in front of the tool such that the drive shaft is connected to the One of the drill holders in position. More particularly, the present invention relates to a hand-held tool having drill holders mounted at angularly spaced locations on a swivel head that can be tilted about an axis relative to the shaft. The axis rotates so that when one of the drill holders is brought to the use position, the drill holder it replaces is simultaneously moved to a storage position arranged behind the use position so as not to interfere with the use of the tool. The invention is particularly (though certainly not exclusively) applicable to tools such as pistol grip power drills designed for one-handed use and having a chuck providing a drill holder for the bit. [0002] Throughout the specification, the terms "dr...
