Saw Or Drill Patents (Class 446/145)
  • Patent number: 10751860
    Abstract: An electric rapid ratchet wrench includes a driving device mounted in a body to which a power device is mounted. A transmission device is mounted between the driving device and the power device and is rotatably mounted to the body. The transmission device transmits a torque from the power device to drive the driving device. A clutch device is mounted between the driving device and the power device. The clutch device includes a driven member and a driver member movable in a radial direction perpendicular to a rotating axis to disengageably engage with the driven member. When a large resistance larger than the torque of the power device is encountered at a position while the driving device is driving a fastener, the driver member repeatedly engages with and disengages from the driven member. The body is manually rotatable to forcibly drive the fastener through the position via the driving device.

  • Patent number: 6062939
    Abstract: A toy power tool is shown having a tool-holding housing and a handle housing rotatably connected at interfacing surfaces inclined to the central axes of both housings. Relative rotation of the housing about a transformation axis perpendicular to the inclined interfacing surfaces transforms the tool from one desired configuration to another. A 180.degree. rotation of the tool-holding housing relative to the handle housing transforms the tool between a straight configuration with the central axes of the housings being aligned, and a L-shaped configuration with the central axes of the housings being at right-angles. Detents between the interfacing surfaces position the housings at the desired configurations, and double as switches that are connected to a sound producing circuit on a printed circuit board mounted parallel to the interfacing surfaces. An internal gear mechanism converts linear input motion to the relative rotary motion of the housings.

  • Patent number: 5470267
    Abstract: A spark producing mechanism for a toy includes an at least partially transparent housing, a rotatable abrasive element in the housing and a motor for rotating the abrasive element. The mechanism further includes at least one flint element which is loosely captured in the housing so that it can contact and carom off the abrasive element to randomly produce sparks in the housing during rotation of the abrasive element.

  • Patent number: 5427528
    Abstract: An activity toy for allowing the user to form artworks from a plastic material such as modeling clay, PLAY-DOH, or plasticene has hand-held extruder for dispensing the plastic material, a first plate upon which the plastic material is disposed so as to form the artwork, and a transparent second plate disposable in laminar juxtaposition to the first plate so as to capture the artwork therebetween.

  • Patent number: 5217402
    Abstract: A sound producing workbench toy includes a molded plastic base supporting a molded plastic work surface. A work station formed of a molded plastic material defines a plurality of receptacles within which various tools and accessories such as simulated nails, screws or bolts may be received. Switch mechanisms within the receptacles are coupled to conventional sound producing circuits and are operative in response to the manipulation of inserted tools, screws, bolts or the like to energize the sound circuits at the appropriate time.

  • Patent number: 5078641
    Abstract: A multi-function toy and in particular to one having a main control body which has a star shaped gear at its axle end that may be adapted with an appropriate bit to act as a cordless screw driver to loosen or tighten this invention. The star shaped gear can also act as a transmission set to drive wheels of a toy vehicle to move.

  • Patent number: 4713036
    Abstract: A toy power driven reciprocating saw workshop is disclosed for simulating the sawing action of a real power driven reciprocating saw cutting a groove through a board. The power driven reciprocating saw workshop having an elongated board having an elongated slot extending therethrough within which an elongated bar is supported adjacent a row of saw teeth on a side of the slot. The saw teeth and one end of the bar form an escapement adapted when one end of the bar is reciprocated and pressed forwardly along the slot by a reciprocating member to intermittently move the bar along the slot one tooth at a time, simulating the sawing action of a real reciprocating saw cutting a groove through a board.

  • Patent number: 4701147
    Abstract: A toy simulated power drill workshop is disclosed for simulating the drilling action of a real power drill in the process of drilling a hole through a board or the like. The toy simulated power drill-workshop having a base member having a first opening extending therethrough, and a plate movably mounted on the base member for covering the first opening. The plate has a second opening alignable with the first opening upon movement of the plate for uncovering the first opening. A driven gear is mounted on the plate with the teeth thereof extending into the first opening. A toy power drill having a rotatably driven cylindrical post with a drive gear on the end thereof is adapted when inserted and pressed into the first opening into engagement with the teeth to rotate the plate until the first and second openings are moved into alignment. During the rotation of the plate, the non-movement of the drill simulates the imperceptible movement of a real drill as it is drilling a hole into a board or the like.
