Definitions

  • the present invention relates to power tools and, more particularly, to techniques for either fixedly or removably attaching a power cord to a common housing for a power tool.
  • Power tools are usually connected to an electric power source (commercial power outlet) via a power cord.
  • the power cord may be fixedly attached to the housing of the power tool or may be removably attached to the housing of the power tool.
  • U.S. Pat. No. 6,368,133 describes a removable power cord that is inserted into a receiving hole provided within the housing of the power tool.
  • a connection terminal for the power tool is disposed within the receiving hole.
  • the shape of the connection end of the power cord is complementary to the shape of the receiving hole of the housing, and a connection terminal is provided for the power cord.
  • the connection end of the power cord is inserted into the receiving hole of the housing.
  • the connection terminal of the power tool is electrically connected to the connection terminal of the power cord.
  • power tools may include a motor that is disposed within a housing.
  • the motor may be arranged and constructed to drive a tool or a tool bit.
  • the housing is preferably defined so as to be capable of receiving either a fixedly attached power cord or a removably attachable power cord without requiring any changes to the housing.
  • a fitting recess e.g., a common fitting recess
  • the fitting recess is preferably designed so as to receive either an adapter (or connector) for a removable power cord or a cord guard for a fixedly secured power cord.
  • the cord guard fitting portion may be disposed within the common fitting recess and no changes to the housing (e.g., the common housing) are necessary.
  • an adapter may be coupled to the motor and may be attached to the housing.
  • an adapter fitting portion e.g., a flange
  • the adapter also may include a connector fitting portion (e.g., an insert or socket).
  • a receiving hole for the removable power cord may be defined within the connector fitting portion.
  • the connector fitting portion is preferably disposed outside of (external to) the housing when the adapter is attached to the housing.
  • the removable power cord may include a cord fitting portion (e.g., a plug), such as a connection end of the power cord.
  • the cord fitting portion e.g., plug
  • the connector fitting portion e.g., socket
  • the removable power cord may be connected to the connector fitting portion, which is attached to the housing. Because the connector fitting portion may be disposed outside the housing, the housing is not required to contain a mechanism or device for connecting to the removable power cord. Therefore, if the adapter is arranged and constructed to engage a housing that is designed for a fixedly attached power cord, a common housing can accommodate both a fixedly attachable power cord and a removably attachable power cord. Therefore, a single housing can be manufactured for each of these applications of the power tool.
  • At least one of the connector fitting portion and the cord fitting portion preferably may include a receiving hole and the other may include an insertion projection.
  • the insertion projection is inserted into the receiving hole.
  • the receiving hole preferably may include one or more projecting terminals and the insertion projection preferably may also include one or more receiving terminals.
  • the projecting terminal(s) may be inserted into the receiving terminal(s). If the projecting terminal(s) are provided within the receiving hole, the projecting terminal(s) will be protected from being deformed or damaged.
  • the receiving hole may be defined within the connector fitting portion.
  • the cord fitting portion may include the insertion projection.
  • the adapter may also include a sleeve that may be secured to the housing in order to support (e.g., rotatably support) the connector fitting portion. Further, one (terminal) end of the sleeve may be disposed beyond the corresponding end of the connector fitting portion. For example, the sleeve may project beyond the end of the connector fitting portion (i.e., the terminal end of the connector fitting portion (or insert) is preferably disposed within the interior of the sleeve).
  • a first projection may be formed on the inner wall of the end of the sleeve.
  • a second (locking) projection may be formed on (or proximal to) the outer wall of the insertion projection of the power cord.
  • the cord fitting portion may be first aligned with the connector fitting portion, so that the insertion projection of the power cord can be inserted into the receiving hole of the connector fitting portion.
  • the connector fitting portion may be substantially in a first position relative to the sleeve, so that the first projection (of the sleeve) does not interfere with the second projection (of the cord fitting portion of the power cord).
  • the insertion projection of the power cord can be pulled (removed) from or inserted into the receiving hole of the connector fitting portion, because the first projection does not interfere with the second projection in the first position.
  • the cord fitting portion and the connector fitting portion may be rotated together about the common rotational axis to (or is disposed in) a second position with respect to the sleeve.
  • the first projection will engage the second projection and/or the first projection (of the sleeve) will prevent the second projection (of the power cord) from passing the first projection.
  • the first and second projections may be disposed in a substantially interlocking position.
  • FIG. 1 is a side view of a screwdriver according to a representative embodiment of the present teachings.
  • FIG. 2 is a longitudinal cross-sectional view of the bottom portion of a handle.
  • FIG. 3 is a cross-sectional view taken along line III-III shown in FIG. 2.
  • FIG. 4 is a perspective view of a representative adapter.
  • FIG. 5 is a longitudinal cross-sectional view of a representative connector fitting portion.
  • FIG. 6 is a cross-sectional view taken along line VI-VI shown in FIG. 5.
  • FIG. 7 is a perspective view of a representative plug.
  • FIG. 8 is a side view of the representative screwdriver with a power cord fixedly attached to the housing.
  • power tools may include a motor (e.g., an electric motor) disposed within a housing.
  • the motor preferably may be adapted to drive the power tool or a tool bit attached to the power tool.
  • An adapter or connector may be electrically connected to the motor and attached to the housing.
  • the adapter may include a connector fitting portion that is disposed external to (outside of) the housing.
  • the connector fitting portion may be defined, e.g., as a socket or insert for receiving a cord fitting portion of a removable power cord.
  • the cord fitting portion may be defined, e.g., as a plug that is arranged and constructed to fit within (or engage with) the connector fitting portion or socket.
  • one of the connector fitting portion and the cord fitting portion may include a receiving hole.
  • the other of the connector fitting portion and the cord fitting portion may include an insertion projection arranged and constructed for insertion into the receiving hole.
  • At least one projecting terminal may be disposed within the receiving hole and at least one receiving terminal may be arranged and constructed to receive the at least one projecting terminal defined within the insertion projection.
  • the receiving hole may be defined within the connector fitting portion and the insertion projection may be defined within the cord fitting portion.
  • the adapter may include a sleeve that supports the connector fitting portion and the sleeve may be attached to the housing.
  • the sleeve may be arranged and constructed to rotatably support the connector fitting portion, such that the connector fitting portion can rotate within the sleeve.
  • One end of the sleeve may be disposed beyond a corresponding end of the connector fitting portion.
  • First projections may be defined on an inner wall of the end of the sleeve and second projections may be defined on an outer wall of the cord fitting portion (e.g., the plug).
  • the cord fitting portion can be inserted into the connector fitting portion when the connector fitting portion is disposed substantially in a first position with respect to the sleeve. In this first position, the first projections do not interfere with the second projections, thereby allowing the insertion projection of the power cord to be pulled (removed) from or inserted into the receiving hole of the connector fitting portion. Then, when the cord fitting portion is rotated about a common rotational axis to a second position with respect to the sleeve, the first projections preferably engage the second projections in order to prevent the insertion projection of the power cord from being pulled (removed) from the receiving hole of the connector fitting portion. For example, the second projections may block the first projections from passing out of the sleeve.
  • a locking mechanism may be utilized to releasably secure the removable power cord to the sleeve.
  • the locking mechanism may be operated or manipulated to release the removable power cord from the sleeve when the connector fitting portion is disposed in the second position with respect to the sleeve.
  • the locking mechanism may include a groove defined in one of the sleeve or the removable power cord.
  • a locking member may be defined on the other of the sleeve and the removable power cord.
  • the locking member disengages from the groove when the locking member has been operated or manipulated from its original or initial position and the locking member engages the groove when the locking member has been released and returned to its original or initial position.
  • the locking member may be arranged and constructed such that the locking member is urged toward the locking position and away from the unlocking position.
  • the locking member may be made of an elastic resin material that urges the locking member toward the locking position and away from the unlocking position.
  • the locking mechanism may also include one or more stoppers arranged and constructed to prevent the locking member from dislodging from the groove. Further, the locking member may be defined on the removable power cord.

  • trigger switch 14 is de-activated (released)
  • the supply of current from the external power source will be stopped. Accordingly, pressing or actuating trigger switch 14 will cause tool bit 16 to rotate and releasing or de-activating trigger switch 14 will cause tool bit 16 to stop rotating.

  • sleeve 33 may be attached to housing 12 by disposing adapter fitting portion 33 a within fitting recess 12 b .
  • housing halves 12 d , 12 e may be assembled around adapter fitting portion 33 a so that the adapter fitting portion 33 a is securely disposed within fitting recess 12 b.
  • adapter fitting portion 33 a and fitting recess 12 b each have a square cross-section, sleeve 33 cannot pivot or rotate with respect to housing 12 .
  • the adapter fitting portion 33 a and fitting recess 12 b may have different, but still complementary configurations, that enable adapter fitting portion 33 a to be non-rotatably disposed within fitting recess 12 b .
  • a wide variety of complementary configurations are known in the art and thus need not be specifically described herein.
  • Adapter 32 is preferably designed to receive removable power cord 61 .
  • plug (e.g., cord fitting portion) 62 may be coupled to one terminal end of power cord 61 .
  • plug 62 may include a substantially cylindrical lower portion.

  • insertion projection 62 a of plug 62 may be inserted into receiving hole 34 b of insert 34 when the insert 34 is disposed substantially in a first position with respect to the sleeve 33 .
  • This insertion operation may be accomplished by moving plug 62 toward adapter 32 in a manner so that projections 33 b of sleeve 33 do not interfere with locking projections 62 b of plug 62 . That is, in the first position, projections 33 b do not interfere or engage locking projections 62 b .
  • pins 35 Upon inserting plug 62 into adapter 32 , pins 35 will be respectively inserted into cylindrical terminals 66 a of terminal holes 66 .
  • the shape of recess 34 c of insert 34 is preferably complementary to the shape of engaging projection 62 d so that insertion projection 62 a can be inserted into receiving hole 34 b . Due to the complementary shapes of engaging projection 62 d and receiving hole 34 b , plug 62 can be inserted into insert 34 only in one particular orientation, which will be referred to as the “first” or “insertion” orientation.
  • locking member 64 should be pressed, e.g., manually pressed, into the unlocked position.
  • plug 62 is rotated approximately 90 degrees from the first or insertion orientation to a second position while keeping plug 62 completely inserted within adapter 32 .
  • locking projections 62 b of plug 62 will contact the rear portions of projections 33 b of sleeve 33 and plug 62 will be prevented from falling out of (or being removed from) adapter 32 when plug 62 is disposed substantially in the second position with respect to sleeve 33 .
  • locking groove 33 c of sleeve 33 coincides with locking member 64 in the circumferential direction. Therefore, when the pressing force applied to locking member 64 is removed or released, locking member 64 will return to the locking position due to its elastic restoring force. Therefore, locking portion 64 a fits into (engages) locking groove 33 c . Because locking portion 64 a is fitted into (engaged with) locking groove 33 c , plug 62 is prevented from pivoting about its longitudinal axis with respect to insert 34 . Further, if stoppers 33 g are defined on both sides of locking groove 33 c , locking portion 64 a can be prevented from dislodging from locking groove 33 c.
  • Projections 33 b of adapter 32 respectively engage locking projections 62 b of plug 62 . Further, locking portion 64 a fits within (engages) locking groove 33 c . Therefore, plug 62 is prevented from moving both along and around its longitudinal axis and plug 62 is positively, but releasably, secured to adapter 32 .
  • locking member 64 may be deformed (e.g., manually pressed), thereby forcing locking portion 64 a out of locking groove 33 c .
  • plug 62 By rotating plug 62 around its longitudinal axis to the first or insertion orientation while continually pressing locking member 64 and then by pulling plug 62 in the axial direction, plug 62 can be disconnected (removed) from adapter 32 .
  • connection/disconnection of plug 62 to/from adapter 32 can be accomplished by a series of actions, such as inserting and rotating (or pivoting) plug 62 and operating locking member 64 . These actions may be manually performed with one hand, thereby enabling “one-touch” operation. Therefore, by using the above-described adapter 32 and plug 62 , connection and removal of the removable power cord 61 is facilitated.
  • Fitting recess 12 b of the present embodiment also enables a power cord to be fixedly attached to housing 12 .
  • a mechanism for receiving and affixing the removable power cord 61 is not provided within housing 12 of screwdriver 10 . Therefore, a common fitting portion (e.g., fitting recess 12 b ) can be utilized in order to affix either the adapter for a removable power cord or a fixed power cord.
  • FIG. 8 shows screwdriver 10 , which is identical to screwdriver 10 shown in FIG. 2, but in which power cord 22 has been fixedly secured to housing 12 .
  • power cord 22 may include cord guard 24 , which prevents power cord 22 from being sharply bent.
  • Fitting portion 24 a may be defined on a terminal end (e.g., an upper end) of cord guard 24 and fitting portion 24 a may have a substantially circular cross-section, although naturally the shape of fitting portion 24 a is preferably designed to be substantially complementary to the shape of fitting recess 12 b .
  • the thickness of fitting portion 24 a may be substantially equal to the height of fitting recess 12 b .
  • cord clamp 27 may be disposed proximally to fitting recess 12 b and cord clamp 27 may be fastened to housing 12 , e.g., by screw 26 .
