  • the implement 131, the implement holder 135, and the circular disk 136, which make up the implement assembly 130, all rotate concurrently one with the others.
  • the plurality of implements 131 are retained within the housing 110 such that the pivot axes "P" are generally parallel to the longitudinal axis "L”; however, this particular alignment is generally a function of the shape of the housing 110.
  • the housing 110 has been made to have a small diameter so that the hand of most users can grasp the housing 110 comfortably.
  • each implement 131 has a shank 132 that is generally straight and is integrally formed with the blade 133.
  • the shank 132 is hexagonally shaped in cross section, as are most screwdriver bits.
  • a deflector receiving portion 134 is disposed in laterally spaced relation from the pivot axis "P", or in other words at a lateral distance from the pivot axis "P", which is located at the centre of the of the implement 131.
  • the chuck 120 is for receiving the implements 131 one at a time, or in other words singularly, in torque transmitting relation by the chuck 120.
  • the chuck 120 has a forward cone portion 121, a rearwardly extending handle engagement portion 122 and a rearwardly extending cylindrical wall portion 123.

  • the chuck 120 defines an implement-receiving opening 125 for receiving the shank 132 of each implement 131 singularly in torque transmitting relation by the chuck 120. More specifically, the front end portion of the implement-receiving opening 125 is defined partially by a torque transmitting section 126 that in the first illustrated embodiment comprises six triangularly shaped surfaces 126 that together define a regular hexagonal shape just slightly greater in size than the regular hexagonal shape of shank 132 of the implement 131. The six triangularly shaped surfaces 126 on the chuck 120 transmits torque to the hexagonally shaped shank 132 of the forwardly extended implement 131. When the selected implement 131 extends through the implement-receiving opening 125, the selected implement 131 is in its extended in-use position.
  • the six triangularly shaped surfaces 126 adjacent the front end of the implement-receiving opening 125 form a hexagonal shape in order to receive the shank 132 of the extended implement 131 in torque transmitting relation.

  • the chuck 120 is mounted on the housing 110 for rotation of the chuck 120 and the housing 110 with respect to each other, about an axis of rotation "R". This rotation is used in order to accommodate the ratchet function of the multi-implement tool 100.
  • the ratchet function is achieved by the rotation-locking mechanism 160 that is operatively interposed between the housing 110 and the chuck 120.
  • the rotation-locking mechanism 160 comprises a bi-directional rotation-locking mechanism 160, and even more specifically comprises a bi-directional ratchet mechanism 160 for in a first configuration, selectively permitting axial rotation of the chuck 120 with respect to the housing 110 about the axis of rotation "R" in a first rotational direction and precluding axial rotation of the chuck 120 with respect to the housing 110 in a second rotational direction, and in a second configuration, selectively permitting axial rotation of the chuck 120 with respect to the housing 110 in a second rotational direction and precluding axial rotation of the chuck 120 with respect to the housing 110 in a first rotational direction.
  • Any suitable rotation locking mechanism can be used.
  • the implements 131 are generally retained within the housing 110 so as to be in non-interfering relation with one another, or in other words to leave sufficient space at the front area of the housing 110 immediately rearwardly of the chuck 120.
  • the plurality of implements 131 are operatively retained within the housing 110 generally in longitudinal alignment with the elongate housing 110, so as to be readily movable to their respective in-use positions.
  • the shank 132 of the one selected implement 131 is received in torque transmitting relation by the torque transmitting section 126, specifically the six triangularly shaped surfaces 126, on the chuck 120 and extends through the implement-receiving opening 125 so as to be able to engage a fastener or the like.
  • the torque transmitting section 126 specifically the six triangularly shaped surfaces 126
  • the housing 110 When a user manually turns the housing about the longitudinal axis "L”, the torque generated by such turning about the longitudinal axis "L" is transmitted through the housing 110, through the chuck 120, and to the shank 132 of the extended implement 131.
  • the rotational direction of force transmission can be either clockwise or counter-clockwise, depending on the selected direction of the bi-directional rotation locking mechanism 160.
  • the means 140 for moving the implements 131, as selected, singularly between the retracted position and the in-use position comprises an actuator mechanism 140 for each implement 131, and specifically six actuator mechanisms 140 in the first illustrated embodiment.
  • Each actuator mechanism 140 comprises a main body 141, a thumb engageable portion 142 disposed exteriorly to the main body 110, a stem portion 143, a forwardly extending hook portion 144 having a rearwardly-facing surface 144a, a rearwardly extending hook portion 146 having a forwardly-facing surface 146a, and a pivot pin 147.
  • the actuator mechanism 140 is operatively connected to its respective implement 131 at the implement holder 135 via an inter-connecting member 149 that pivotally connects to the base 137 at the pivot pin 139 and also pivotally connects to the actuator mechanism 140 at the pivot pin 147.
  • the stem portion 143 of the actuator mechanism 140 extends through a slot 113 in the main body 110 and interconnects the main body 141 and the thumb engageable portion 142.
  • the forwardly-facing surface 146a of the rearwardly extending hook portion 146 engages a co-operating surface at or adjacent the back end 112 of the housing 110 in removable relation to retain the respective implements 131 in their retracted positions.
  • the means 150 for selectively retaining an implement 131, specifically the selected implement 131, in the forwardly extended in-use position comprises a forwardly facing abutment surface 115 disposed on the inner wall surface 116 of the housing 110.
  • the co-operating rearwardly-facing surface 144a on the forwardly extending hook portion 144 of the actuator mechanism 140 securely engages the forwardly facing abutment surface 115 to thereby retain the selected implement 131 in its forwardly extended in-use position.
  • the plurality of implements 131 are operatively retained by the housing 110 each for free rotation about its respective pivot axis "P", as discussed above, and for longitudinal movement between a retracted position, as is best seen in Figures 1 , 3 , 5 , 6 and 7A , and a forwardly extended in-use position, as is best seen in Figures 2 , 4 and 12 .
  • the shank 132 of the implement 131 in the unaligned pivotal orientation of each implement 131, the shank 132 of the implement 131 is pivotally unaligned about the pivot axis "P" with respect to torque transmitting section 126 of the chuck 120 adjacent the front of the implement-receiving opening 125 of the chuck 120.
  • the pivot-inducing deflector 170 is operatively mounted on the chuck 120 so as to be disposed in laterally spaced relation from the pivot axis "P", as discussed above. More specifically, the pivot-inducing deflector 170 is disposed on the chuck 120, and even more specifically, the pivot-inducing deflector 170 is integrally formed on the chuck 120. As can be readily seen, the pivot-inducing deflector 170 comprises an obliquely angled guide surface 174, and more specifically comprises a plurality of angled guide surfaces 170, and as seen in the illustrated embodiment, six obliquely angled guide surfaces 170.
  • the number of guide surfaces 170 corresponds to the number of deflector receiving portions 134, namely six, on the implements 131.
  • the lateral distance between the pivot-inducing deflector 170 and the longitudinal axis "L” acts as a moment arm for causing rotation of the implement about the longitudinal axis "L".
  • each pivot-inducing deflector 170 is sloped along a portion of the longitudinal axis "L" from a first end 171 of the pivot-inducing deflector 170 at a first radial angular position to a second end 172 of the pivot-inducing deflector 170 at a second radial angular position.
  • the second end 172 of the pivot-inducing deflector 170 is closer to the chuck 120 than is the first end 171 of the pivot-inducing deflector 170.
  • the first end 171 comprises a rear apex 171a that is substantially unrounded, or in other words is angled and not rounded.
  • pivot-inducing deflector 170 is substantially flat and slopes in one direction only. Accordingly, with the first end of the pivot-inducing deflector 170 shaped as described, the chance of the selected implement 131 abutting against the first end 171 of the pivot-inducing deflector 170 and not readily moving further forwardly, or even not moving further forwardly, is substantially precluded.
  • the pivot-inducing deflector 170 is disposed adjacent the implement receiving opening 125 of the chuck so as to be in an advantageous position to pivotally deflect the selected implement 131 just before it enters the torque transmitting section 126 of the chuck 120 adjacent the front of the implement receiving opening 125.
  • the pivot-inducing deflector 170 is for engaging the selected implement 131 that is being moved to its forwardly extended in-use position, to thereby pivot the selected implement 131 about its pivot axis "P", to thereby pivotally align the implement 131 about the pivot axis "P" with respect to the torque transmitting section 126 of the chuck 120 adjacent the implement-receiving opening 125 of the chuck 120 as the selected implement 131 is being moved to its extended in-use position, to thereby permit the chuck 120 to engage the selected implement 131 in torque transmitting relation.
  • FIGS 6 through 12 show the pivotal alignment of the selected 131 as it is moved forwardly from its retracted position to its forwardly extended in-use position.
  • the pivot-inducing deflector 170 is in position to receive the deflector receiving portion 134 of the selected implement 131, as the selected implement 131 is moved forwardly from it retracted position to its forwardly extended in-use position.

  • the six deflector receiving portions 134 of the shank 132 of the selected implement 131 are adjacent the apexes of the hexagonally shaped shank 132.
  • One deflector receiving portion 134 is to be received by each of the obliquely angled guide surfaces 174.
  • No portion of the selected implement 131 is yet in the implement-receiving opening 125, which is therefore unoccupied.
  • Figure 7A shows the unoccupied implement-receiving opening 125 and the pivot-inducing deflector 170, or more specifically stated, the six obliquely angled guide surfaces 174, from behind, basically from the point of view of the selected implement as it is moved forwardly from its retracted position.
  • pivot-inducing deflector surfaces 174 which would cover one-sixth (sixty degrees) of the circumference of the implement-receiving opening 125, since there are six deflector receiving portions 134 spaced equally radially apart around the perimeter of the hexagonal shank 132 of each implement 131.
  • each deflector receiving portion 134 spaced equally radially apart around the perimeter of the hexagonal shank 132 of each implement 131 could each cover one-sixth (sixty degrees) of the circumference of the implement 131, and one single pivot-inducing deflector surface 174 could cover a very small radial area if desired.

  • the implement 131 has not pivoted about its pivot axis "P" and accordingly, the shank 132 of the selected bit 131 remains angularly misaligned with respect to torque transmitting section 126 of the chuck 120 adjacent the front of the implement-receiving opening 125 of the chuck 120.
  • FIGS 9A and 9B show a selected implement 131 having been moved slightly more forwardly towards its extended in-use position.
  • the six deflector receiving portions 134 each contact a corresponding one of the pivot-inducing deflector surfaces 174 of the pivot-inducing deflector 170.

  • the pivot-inducing deflector 170 causes the selected implement 131 to pivot about its pivot axis "P" in a counter-clockwise rotational direction, as indicated by arrow "P1". Accordingly, the shank 132 of the selected implement 131 remains angularly misaligned with respect to the torque transmitting section 126 of the chuck 120 adjacent the front of the implement-receiving opening 125 of the chuck 120. As shown, the deflector receiving portions 134 are nearly at the half-way point along each corresponding pivot-inducing deflector surface 174.

  • the chuck 220 defines an implement-receiving opening 225 for receiving the shank 232 of each implement assembly 230 singularly in torque transmitting relation by the chuck 220. More specifically, the front end portion of the implement-receiving opening 225 is defined partially by a torque transmitting section 226 that comprises six generally triangularly shaped surfaces 226 that together define a regular hexagonal shape just slightly greater in size than the hexagonally shaped shank 232 of the implement 231. The six triangularly shaped surfaces 126 on the chuck 220 transmit torque to the hexagonally shaped shank 232 of the implement 231 of the forwardly extended implement assembly 230.

  • Other suitable cross-sectional shapes could also be used for the implement-receiving opening 225 and the shank 232 of the implements 231.
  • the chuck 220 is mounted on the housing 210 for rotation of the chuck 220 and the housing 210 with respect to each other, about an axis of rotation "R". This rotation is used in order to accommodate the ratchet function of the multi-implement tool 200.
  • the ratchet function is achieved by the rotation-locking mechanism 260 that is operatively interposed between the housing 210 and the chuck 220.
  • the rotation-locking mechanism 260 comprises a bi-directional rotation-locking mechanism 260, and even more specifically comprises a bi-directional ratchet mechanism 260 for in a first configuration, selectively permitting axial rotation of the chuck 220 with respect to the housing 210 about the axis of rotation "R" in a first rotational direction and precluding axial rotation of the chuck 220 with respect to the housing 210 in a second rotational direction, and in a second configuration, selectively permitting axial rotation of the chuck 220 with respect to the housing 210 in a second rotational direction and precluding axial rotation of the chuck 220 with respect to the housing 210 in a first rotational direction.
  • Any suitable rotation locking mechanism can be used.
  • the implement assemblies 230 are generally retained within the housing 210 so as to be in non-interfering relation with one another, or in other words to leave sufficient space at the front area of the housing 210 immediately rearwardly of the chuck 220.
  • the plurality of implement assemblies 230 are operatively retained within the housing 210 generally in longitudinal alignment with the elongate housing 210, so as to be readily movable to their respective in-use positions.
  • the shank 232 of the implement 231 of the one selected implement assembly 230 is received in torque transmitting relation by the torque transmitting section 226, specifically the six triangularly shaped surfaces 226, on the chuck 220 and extends through the implement-receiving opening 225 so as to be able to engage a fastener or the like.
  • the rotational direction of force transmission can be either clockwise or counter-clockwise, depending on the selected direction of the bi-directional rotation locking mechanism 260.
  • the means 240 for moving the implement assemblies 230, as selected, singularly between the retracted position and the in-use position comprises an actuator mechanism 240 for each implement assembly 230, and specifically six actuator mechanisms 240 in the second illustrated embodiment.
  • the actuator mechanism 240 comprises a main body 241, a thumb engageable portion 242 disposed exteriorly to the main body 210, a stem portion 243, a forwardly extending hook portion 244 having a rearwardly-facing surface 244a, a rearwardly extending hook portion 246 having a forwardly-facing surface 246a, and a pivot pin 247.
  • the actuator mechanism 240 is operatively connected to its respective implement assembly 230 at the implement holder 235 via an inter-connecting member 249 that pivotally connects to the base 237 at the pivot pin 239 and also pivotally connects to the actuator mechanism 240 at the pivot pin 247.
  • the stem portion 243 of the actuator mechanism 240 extends through a slot 213 in the main body 210 and interconnects the main body 241 and the thumb engageable portion 242.
  • the forwardly-facing surface 246a of the rearwardly extending hook portion 246 engages a co-operating surface at or adjacent the back end 212 of the housing 210 in removable relation to retain the respective implement assemblies 230 in their retracted positions.
  • the means 250 for selectively retaining an implement assembly 230, specifically the selected implement assembly 230, in the forwardly extended in-use position comprises a forwardly facing abutment surface 215 disposed on the inner wall surface 216 of the housing 210.
  • the co-operating rearwardly-facing surface 244a on the forwardly extending hook portion 244 of the actuator mechanism 240 securely engages the forwardly facing abutment surface 215 to thereby retain the selected implement assembly 230 in its forwardly extended in-use position.
  • the plurality of implement assemblies 230 are operatively retained by the housing 210 each for free rotation about its respective pivot axis "P", as discussed above, and for longitudinal movement between a retracted position, as is best seen in Figures 14 and 15A , and a forwardly extended in-use position, as is best seen in Figures 13 and 20 .
  • the shank 232 of the implement 231 is pivotally unaligned about the pivot axis "P" with respect to the torque transmitting section 226 of the chuck 220 adjacent the front of the implement-receiving opening 225 of the chuck 220.
  • the shank 232 of the implement 231 of the implement assembly 230 is pivotally aligned about the pivot axis "P" with respect to the torque transmitting section 226 of the chuck 220 adjacent the front of the implement-receiving opening 225 of the chuck 220.
  • the pivoting of the selected implement assembly 230 is described in greater detail subsequently.
  • the shank 232 of the implement 231 of the implement assembly 230 is pivotally aligned about the pivot axis "P" with respect to the torque transmitting section 226 of the chuck 220 adjacent the front of the implement-receiving opening 225 of the chuck 220.
  • the pivoting of the selected implement assembly 230 is described in greater detail subsequently.
  • the pivot-inducing deflector 270 is operatively mounted on the chuck 220 so as to be disposed in laterally spaced relation from the pivot axis "P", as discussed above. More specifically, the pivot-inducing deflector 270 is disposed on the chuck 220, and even more specifically, the pivot-inducing deflector 270 is integrally formed on the chuck 220. As can be readily seen, the pivot-inducing deflector 270 comprises an obliquely angled guide surface 274, and more specifically comprises a plurality of angled guide surfaces 270, and as seen in the illustrated embodiment, six obliquely angled guide surfaces 270.
  • the number of guide surfaces 270 corresponds to the number of deflector receiving portions 234, namely six, on the implement assemblies 230.
  • the lateral distance between the pivot-inducing deflector 270 and the longitudinal axis "L” acts as a moment arm for causing rotation of the implement about the longitudinal axis "L".
  • each pivot-inducing deflector 270 is sloped along a portion of the longitudinal axis "L" from a first end 271 of the pivot-inducing deflector 270 at a first radial angular position to a second end 272 of the pivot-inducing deflector 270 at a second radial angular position.
  • the second end 272 of the pivot-inducing deflector 270 is closer to the chuck 220 than is the first end 271 of the pivot-inducing deflector 270.
  • the first end 271 comprises a rear apex 271a that is substantially unrounded, or in other words is angled and not rounded.
  • pivot-inducing deflector 270 is substantially flat and slopes in one direction only. Accordingly, with the first end of the pivot-inducing deflector 270 shaped as described, the chance of the selected implement assembly 230 abutting against the first end 271 of the pivot-inducing deflector 270 and not readily moving further forwardly, or even not moving further forwardly, is substantially precluded.
  • pivot-inducing deflector 270 is disposed adjacent the implement receiving opening 225 of the chuck so as to be in an advantageous position to pivotally deflect the selected implement assembly 230 just before it enters the torque transmitting section 226 of the chuck 220 adjacent the front of the implement receiving opening 225.
  • the pivot-inducing deflector 270 is for engaging the selected implement assembly 230 that is being moved to its forwardly extended in-use position, to thereby pivot the selected implement assembly 230 about its pivot axis "P", to thereby pivotally align the implement assembly 230 about the pivot axis "P" respect to the torque transmitting section 226 of the chuck 220 adjacent the front of with the implement-receiving opening 225 of the chuck 220 as the selected implement assembly 230 is being moved to its extended in-use position, to thereby permit the chuck 220 to engage the selected implement assembly 230 in torque transmitting relation.
  • FIGS 13 through 20 show the pivotal alignment of the selected implement assembly 230 as it is moved forwardly from its retracted position to its forwardly extended in-use position.
  • the pivot-inducing deflector 270 is in position to receive the deflector receiving portion 234 of the selected implement assembly 230, as the selected implement assembly 230 is moved forwardly from its retracted position to its forwardly extended in-use position.
  • the six obliquely angled guide surfaces 274 are in position to receive the six deflector receiving portions 234 of the selected implement assembly 230.
  • the six deflector receiving portions 234 of the shank 232 of the selected implement assembly 230 are adjacent the apexes of the hexagonally shaped shank 232.
  • One deflector receiving portion 234 is to be received by each of the obliquely angled guide surfaces 274.
  • No portion of the selected implement assembly 230 is yet in the implement-receiving opening 225, which is therefore unoccupied.
  • Figure 15A shows the unoccupied implement-receiving opening 225 and the pivot-inducing deflector 270, or more specifically stated, the six obliquely angled guide surfaces 274, from behind, basically from the point of view of the selected implement as it is moved forwardly from its retracted position.
  • pivot-inducing deflector surfaces 274 which would cover one-sixth (sixty degrees) of the circumference of the implement-receiving opening 225, since there are six deflector receiving portions 234 spaced equally radially apart around the perimeter of the hexagonal shank 232 of each implement assembly 230.
  • each deflector receiving portion 234 spaced equally radially apart around the perimeter of the hexagonal shank 232 of each implement 231 of each implement assembly 230 could each cover one-sixth (sixty degrees) of the circumference of the implement assembly 230, and one single pivot-inducing deflector surface 274 could cover a very small radial area if desired.
  • FIGS 16A and 16B show a selected implement assembly 230 having been moved forwardly from its retracted position and towards its extended in-use position, and directed inwardly towards the longitudinal axis "L" by the rearwardly facing implement guide surface 218.
  • the deflector receiving portions 234 of the selected implement assembly 230 are each in operative engagement with the pivot-inducing deflector surface 274 (although only two are viewable) and showing the selected hexagonally shaped implement assembly 230 in the hexagonally shaped implement-receiving opening 225.
  • the implement assembly 230 has not pivoted about its pivot axis "P" and accordingly, the shank 232 of the implement of the selected implement assembly 230 remains angularly misaligned with respect to the torque transmitting section 226 of the chuck 220 adjacent the front of the implement-receiving opening 225 of the chuck 220.
  • FIGS 17A and 17B show a selected implement assembly 230 having been moved slightly more forwardly towards its extended in-use position.
  • the six deflector receiving portions 234 each contact a corresponding one of the pivot-inducing deflector surfaces 274 of the pivot-inducing deflector 270.
  • the deflector receiving portions 234 of the selected implement assembly 230 each remain in operative engagement with the pivot-inducing deflector surface 274 (although only two are viewable) each by sliding along the respective pivot-inducing deflector surface 274.
  • the hexagonally shaped shank 232 of the implement 231 of the selected implement assembly 230 is about to enter the hexagonally shaped implement-receiving opening 225.
  • the pivot-inducing deflector 270 causes the selected implement assembly 230 to pivot about its pivot axis "P" in a counter-clockwise rotational direction, as indicated by arrow "P1". Accordingly, the shank 232 of the implement of the selected implement assembly 230 remains angularly misaligned with respect to the implement-receiving opening 225 of the chuck 220.
  • the deflector receiving portions 234 are nearly at the half-way point along each corresponding pivot-inducing deflector surface 274.
  • the deflector receiving portions 234 of the selected implement assembly 230 still each remain in operative engagement with the pivot-inducing deflector surface 274 (although only two are viewable) each by sliding along the respective pivot-inducing deflector surface 274.
  • the hexagonally shaped shank 232 of the implement of the selected implement assembly 230 is still about to enter the hexagonally shaped implement-receiving opening 225.
  • the pivot-inducing deflector 270 continues to cause the selected implement assembly 230 to pivot about its pivot axis "P" in a counter-clockwise rotational direction, as indicated by arrow "P2".
  • the shank 232 of the implement 231 of the selected implement assembly 230 still remains angularly misaligned with respect to the torque transmitting section 226 of the chuck 220 adjacent the front of the implement-receiving opening 225 of the chuck 220.
  • the deflector receiving portions 234 are past the half-way point along each corresponding pivot-inducing deflector surface 274.
  • the pivot-inducing deflector 270 continues to cause the selected implement assembly 230 to pivot about its pivot axis "P" a final amount in a counter-clockwise rotational direction, as indicated by arrow "P3".
  • the deflector receiving portions 234 have reached the ends of the respective pivot-inducing deflector surfaces 274, and are aligned with the correspondingly shaped apexes of the implement-receiving opening 225.
