Description

POWER TOOL COMPRISING A NOSE CAP WITH AN ELECTRICALLY POWERED ASSEMBLYTECHNICAL FIELD

[0001] The present disclosure relates to power tools, such as rotary tools.BACKGROUND

[0002] Power tools, such as rotary tools are a favorite instrument of professional craftsmen, handymen, homeowners, and hobbyists. The typical rotary tool is a handheld power tool configured for use with a variety of accessory bits / tools that can be used for cutting, carving, sanding, polishing, and many other applications, referred to collectively as cutting operations. One specific example of a rotary tool is the DREMEL® rotary tool sold by the Robert Bosch Tool Corporation.

[0003] Many rotary tools include a collet assembly coupled to the drive shaft of an electric motor. The collet assembly is configurable to couple or to decouple an accessory bit to the drive shaft of the electric motor. The electric motor is operable to rotate the collet assembly and any accessory bit coupled thereto. The accessory bit may be removed and replaced with a different accessory bit when the accessory bit becomes nonfunctional or when the user desires to perform a different cutting operation. Typically, a collet tool is provided to loosen or tighten the collect assembly. The DREMEL® EZ Twist™ Nose Cap may be used as such a collet tool. The EZ Twist™ Nose Cap also provides a good grip of the rotary tool close to its accessory bit. The EZ Twist™ Nose Cap has an integrated wrench for fast accessory changes. It is always handy because it is already on the tool. It can be used on all rotary tools with a corresponding threaded nose piece. Its soft grip provides additional comfort.

[0004] It would be desirable to further enhance such a power tool and its nose cap.SUMMARY

[0032] The illustrated embodiments are disclosed with reference to the drawings. However, it is to be understood that the disclosed embodiments are intended to be merely examples that may be embodied in various and alternative forms. The figures are not necessarily to scale andsome features may be exaggerated or minimized to show details of particular components. The specific structural and functional details disclosed are not to be interpreted as limiting, but as a representative basis for teaching one skilled in the art how to practice the disclosed concepts.

[0033] Fig. 1, 2, 3, and 4 show a rotary tool 10. The rotary tool 10 may include a handle portion 12 that extends away from the rotary tool 10 as hinted at in Fig. 1 with dashed lines. Instead of the depicted rotary tool 10 the disclosure may also apply to another power tool such as an oscillating tool, a saw, a brush, drill, a driver, a drill / driver, a rotary hammer, or a wrench. The rotary tool 10 comprises a housing portion 14 extending along an axial direction 16. The housing portion 14 may be the entire housing as depicted. It may also be a portion of a larger housing as may the case with a power tool such as a right-angle drill or drill / driver. The rotary tool 10 contains a motor 18 (dashed box) with a drive shaft 20. The motor 18 and hence the rotary tool 10 are activated with a trigger 22. The rotary tool 10 further includes a nose piece 24 protruding from the housing portion 14 at a first axial end 26 of the rotary tool 10. The rotary tool 10 further comprises a spindle 28 attached to the drive shaft 20. The spindle 28 defines an axis of rotation 30 extending along the axial direction 16 and protruding from the nose piece 24.

[0034] A nose cap 32 is removably attached to the nose piece 24. The spindle 28 protrudes further from the nose cap 32. The nose cap 32 extends in an axial direction 16 and has an axis 34 extending along the axial direction 16. The axis 34 is in line with the axis of rotation 30 of the spindle 28. The nose cap 32 is generally of cylindrical shape. For a better grip for a user the nose cap 32 may have a grip portion 36 on the outside. The grip portion 36 may have a smaller diameter in the middle and a larger diameter at the longitudinal ends of the nose cap 32.

[0035] The nose cap 32 is affixed to the nose piece 24 by twisting the nose cap 32 in a first rotary direction 38. The nose cap 32 is removed from the nose piece 24 by twisting the nose cap 32 in a second rotary direction 40 opposite from the first rotary direction 38. An electrically powered work light 42 is contained in the nose cap 32 and powered by a power source of the rotary tool 10. The power source is integrated in the rotary tool 10 and activated by the trigger 22. That power source also supplies the motor 18 of the rotary tool 10. The work light 42 illuminates a work area in front of the rotary tool. The work light 42 is arranged at a nose cap 32 front side which extends transversely to the axial direction 16. Instead of a work light 42 the nosecap 32 may be part of a laser, a vacuum, or a fan. In this case the nose cap 32 may contain or supply power to another electrically powered assembly such as the mentioned laser, vacuum, or fan. Dashed box 43 symbolizes a powered assembly such as a laser, vacuum or fan.

[0036] The rotary tool 10 further comprises an electrical connection 44 between the nose cap 32 and the housing portion 14. The electrical connection 44 is closed by twisting the nose cap 32 in the first rotary direction 38. The electrical connection 44 is opened by twisting the nose cap 32 in the second rotary direction 40.

[0037] The electrical connection 44 comprises a first nose cap terminal 46 and a second nose cap terminal 48 arranged on the nose cap 32. The first nose cap terminal 46 and the second nose cap terminal 48 extend transversely to the axial direction 16. The first nose cap terminal 46 and the second nose cap terminal 48 are arranged on a first nose cap side 50 extending transversely to the axial direction 16. The first nose cap terminal 46 comprises a first contact surface 52 and the second nose cap terminal 48 comprises a second contact surface 54. The first contact surface 52 and the second contact surface 54 define a plane 56 extending transversely to the axial direction 16. The contact surfaces 52, 54 may be arranged at a radial distance from a central axis 34 of the nose cap 32. They may be arranged at the same distance or different distances. Hence, they are radially spaced from the central axis 34. The first contact surfaces 52 is arranged opposite from the second contact surface 54. This results in an angle of 180 degrees. They may also be arranged at a different angle, e.g. 90 degrees. The first contact surface 52 and second contact surface 54 are flat. They may also extend in the axial direction 16.

[0038] The electrical connection 44 comprises a first housing terminal 58 and a second housing terminal 60 arranged on the housing portion 14. The first nose cap terminal 46 is brought into electrically conductive contact with the first housing terminal 58 and the second nose cap terminal 48 is brought into an electrically conductive contact with the second housing terminal 60 by twisting the nose cap 32 in the first rotary direction 38. The first nose cap terminal 46 is removed from electrically conductive contact with the first housing terminal 58 and the second nose cap terminal 48 removed from electrically conductive contact with the second housing terminal 60 by twisting the nose cap 32 in the second rotary direction 40.

[0039] The electrical connection 44 defines contact surfaces that extend transversely to the axial direction 16. These contact surfaces are arranged at a radial distance from the axis 34. The contact surfaces are therefore non-mating in the sense that a male connector is inserted into a female connector with a movement along or parallel to the axial direction 16. The contact surfaces comprise a first pin extending in the axial direction 16 and a second pin extending in the axial direction 16 as well as a corresponding first contact surface 52 and a corresponding second contact surface 54, the first pin is aligned with the first contact surface 52 and the second pin is aligned with the second contact surface 54 when the first nose cap terminal 46 is brought into electrically conductive contact with the first housing terminal 58 and the second nose cap terminal 48 is brought into an electrically conductive contact with the second housing terminal 60.

[0044] Fig. 5, 6 and 7 show a second embodiment of a nose cap. Nose cap terminals have a different orientation. Instead of two axial contacts on the same surface, there is only one axial contact and one that is radial.

[0045] Fig. 8, 9 and 10 show a further embodiment of a rotary tool 10’ and a nose cap 32’. Parts that correspond to parts of Fig. 1, 2, 3 and 4 of the first embodiment have the same reference numbers. Parts that are modified have a ‘ added. Instead of the depicted rotary tool 10’ the disclosure may also apply to another power tool such as an oscillating tool, a saw, a brush, drill, a driver, a drill / driver, a rotary hammer, or a wrench. The rotary tool 10’ comprises a housing portion 14’ extending along an axial direction 16. The housing portion 14’ may be the entire housing as depicted. It may also be a portion of a larger housing as may the case with a power tool such as a right-angle drill or drill / driver. The rotary tool 10’ contains a motor with a drive shaft 20. The motor and hence the rotary tool 10’ are activated with a trigger similar to the one in Fig. 1. The rotary tool 10’ further includes a nose piece 24 protruding from the housing portion 14’ at a first axial end 26 of the rotary tool 10’. The rotary tool 10’ further comprises a spindle 28 attached to the drive shaft 20. The spindle 28 defines an axis of rotation 30 extending along the axial direction 16 and protruding from the nose piece 24.

[0046] The nose cap 32’ is removably attached to the nose piece 24. The spindle 28 protrudes further from the nose cap 32’. The nose cap 32’ extends in an axial direction 16 and has an axis 34 extending along the axial direction 16. The axis 34 is in line with the axis of rotation 30 of the spindle 28. The nose cap 32’ is generally of cylindrical shape. For a better grip for a user the nose cap 32’ may have a grip portion 36 on the outside. The grip portion 36 mayhave a smaller diameter in the middle and a larger diameter at the longitudinal ends of the nose cap 32’.

[0047] The nose cap 32’ is affixed to and removed from the nose piece 24 by twisting the nose cap 32’ in the same manner as the nose cap 32’ of the first embodiment. A work light 42 is also powered by a power source of the rotary tool 10’. Instead of a work light 42 the nose cap 32’ may also be part of a laser, a vacuum, or a fan. The nose cap 32’ may contain or supply power to another electrically powered assembly such as the mentioned laser, vacuum, or fan.

[0048] The rotary tool 10’ further comprises an electrical connection 44 between the nose cap 32’ and the housing portion 14’. The electrical connection 44 is closed by twisting the nose cap 32’ in a first rotary direction 38. The electrical connection 44 is opened by twisting the nose cap 32’ in a second rotary direction 40.

[0049] The electrical connection 44 comprises a first nose cap terminal 46’ and a second nose cap terminal 48’ arranged on the nose cap 32’. The first nose cap terminal 46’ and the second nose cap terminal 48’ extend transversely to the axial direction 16. The first nose cap terminal 46’ and the second nose cap terminal 48’ are arranged on a first nose cap. The first nose cap terminal 46’ comprises a first contact surface 52’ and the second nose cap terminal 48’ comprises a second contact surface 54’. The contact surfaces 52’, 54’ may be arranged at a radial distance from a central axis 34 of the nose cap 32’. They may be arranged at the same distance or different distances. Hence, they are radially spaced from the central axis 34. The first contact surfaces 52’ is arranged opposite from the second contact surface 54’. This results in an angle of 180 degrees. They may also be arranged at a different angle, e.g. 90 degrees. The first contact surface 52’ and second contact surface 54’ may be pointed and extend in the axial direction 16 towards the housing portion 14’. The first contact surface 52’ and second contact surface 54’ may also be rounded or flat.

[0050] The electrical connection 44 further comprises a first housing terminal 58’ and a second housing terminal 60’ arranged on the housing portion 14’. The first housing terminal 58’ and a second housing terminal 60’ are flat. The first nose cap terminal 46’ is brought into electrically conductive contact with the first housing terminal 58’ and the second nose cap terminal 48’ is brought into an electrically conductive contact with the second housing terminal60’ by twisting the nose cap 32’ in the first rotary direction 38. The first nose cap terminal 46’ is removed from electrically conductive contact with the first housing terminal 58’ and the second nose cap terminal 48’ is removed from electrically conductive contact with the second housing terminal 60’ by twisting the nose cap 32’ in the second rotary direction 40. The first housing terminal 58’ is wider than the first nose cap terminal 46’ and the second housing terminal 60’ is wider than the second nose cap terminal 48’.

[0051] The electrical connection 44 defines contact surfaces that extend transversely to the axial direction 16. These contact surfaces are arranged at a radial distance from the axis 34. The contact surfaces are therefore non-mating in the sense that a male connector is inserted into a female connector with a movement along or parallel to the axial direction 16.
