16 claims: 11 independent, 5 dependent

  1. 1
    I claim:1. A portable tool comprising, a body, a handle pivoted to the rear of said body for movement from a locked position to an operating range, detent means carried by said body, cooperating movable detent means carried by said handle for locking said handle in said locked position, a single spring for counterbalancing the weight of said handle when in its operating range and for biasing said movable detent means toward its locking position and second detent means carried by said body and engageable with said movable detent means for locking said handle from movement from an inclined operating position to a lower operating position, said spring also biasing said movable detent means into locking engagement with said second detent means.
  2. 2
    A suction cleaner comprising, a body, a handle pivoted to the rear of said body for movement from a non-operating position to an operating range, said handle also being mounted for limited movement relative to said body other than said pivotal movement, detent means carried by said body, coperating detent means on said handle for locking said handle in said nonoperating position, said handle detent means being movable into and out of engagement with said body detent means , by said handle by other than pivotal movement thereof, a single spring for counter-balancing a substantial portion of the weight of said handle and for biasing said handle detent means into position to engage said body detent means and second detent means carried by said body for engagement with said handle detent means for locking said handle against movement from one operating range to a different operating range, said handle detent means being movable into and out of engagement with said second detent means by said other handle movement.
  3. 3
    A suction cleaner comprising, a body, a handle, means for attaching said handle to said S, 526,282 body rearwardly of the center of gravity thereof, said attaching means including means providing for rotary movement of said handle on its longitudinal axis and pivotal movement thereof with respect to said cleaner body from a nonoperating position to an operating range, a single spring for resisting both said rotary movement and said pivotal movement and means including said handle for positively locking said handle in said non-operating position, said means being releasable by rotary movement of said handle against the bias of said spring.
  4. 5
    A suction cleaner comprising, a body, a handle pivoted to the rear of said body for movement from a vertical storage position to an inclined operating position, said handle having limited rotary movement on its longitudinal axis, detent means on said body, detent means on the lower end of said handle engageable with said body detent means to lock said handle in its vertical storage position and being disengageable therefrom by a rotary movement of said handle and a single spring for resisting both rotary and pivotal movement of said handle.
  5. 7
    A suction cleaner comprising, a body, a handle movably attached to said body, said attaching means including a pivot pin carried by said body, a handle socket mounted on said pin for receiving said handle, the lower end of said handle being shaped to form a locking detent, a cooperating detent carried by said body, said handle having limited freedom for rotary movement in said socket to permit said handle locking detent to be disengaged from the detent on said body, a spring having one end anchored to said handle and the other end to said body in such manner as to bias said handle against pivotal movement about said pivot pin in one direction and to bias said handle detent so as to lock said handle against pivotal movement with respect to said body.
  6. 10
    A handle control for a suction cleaner comprising a handle socket pivoted to a cleaner body, an operating handle carried by said socket and having limited rotary movement with respect thereto, a control sector carried by said cleaner body, the end of said cleaner handle being formed and so positioned with respect to said sector as to permit or prevent pivotal movement of said handle with respect to said cleaner body whereby an operator may lock or unlock said handle by a slight bodily rotary movement thereof.
  7. 11
    The combination defined in the preceding claim characterized by the provision of means normally biasing said handle toward locking engagement with said control sector.
  8. 12
    The combination claimed in claim 11 characterized in the provision of common means for biasing said handle toward locking engagement with the control sector and for urging pivotal movement of said handle in one direction.
  9. 13
    In combination with a floor cleaning tool for treating a floor surface, an operating handle pivoted to said tool for pivotal movement in a vertical plane and having limited rotary movement on the longitudinal axis thereof, handle position control means carried by said tool opposite the lower end of said handle, the lower end of said handle being shaped and positioned to cooperate with said control means and operable to permit unrestricted pivotal movement of the handle in one direction but to lock said handle against pivotal movement in the opposite direction whereby the pivotal movement of said handle can be controlled from the operating end thereof by a slight, bodily rotary movement of said handle.
  10. 15
    A handle control as defined in claim 13 characterized in that the lower end of said handle and said stops are shaped to permit free upward movement of said handle from any operating position but which positively lock the handle against downward movement from one fange to another unless the handle is rotated bodily to permit over-riding of a stop.
  11. 16
    In combination, a tool for movement over a surface to be treated,, an operating handle pivoted thereto for movement in a predetermined plane, said handle being arranged for limited axial rotary movement, control means carried by said tool opposite the lower end of said handle, the lower end of said handle being shaped and positioned to cooperate with said last named means to control the pivoted position of said handle, the arrangement being such that the handle can be released for movement from one operating range to another by slight bodily rotary movement, and means normally biasing said, handle against said bodily rotary movement.
