Suction cleaner

Claim 2

In a floor care appliance, a. a body, b. a propelling handle rotatably mounted on said body for movement to one position and to other positions relative to said body, c. a mOtor for the floor care appliance, d. an electric switch for said motor and having a member movable to positions which open and close said switch, e. switch actuating means controlled by movement of said handle for moving said switch member to respectively open and close said switch member to respectively open and close said switch upon movement of said handle to its said one position and to its said other positions, f. and said switch actuating means mounted for movement independently of said handle when said handle is in its said one position for shifting said switch actuating means relative to said switch member to control operation of the latter and thus said switch.

Claim 3

In a floor care appliance as described in claim 1, and cooperating latch means on said handle and switch actuating means operative after the latter has been moved in one direction independently of handle movement to latch said switch actuating means to said handle in closed switch position.

Claim 4

In a floor care appliance as described in claim 1, and resilient means urging said switch actuating means into operative relation with said handle for movement with the latter when said handle is moved to its said one position and to its said other positions to open and close said switch.

Claim 5

In a floor care appliance, a. a body, b. a filter for receiving dirt removed from the surface being cleaned, c. a bag latch for securing said filter to said body and including resilient means to retain the latch in filter-securing position, d. a propelling handle rotatably mounted on said body for movement to one position and to other positions relative to said body, e. a motor for the floor care appliance, f. an electric switch for said motor, g. switch operating means controlled by movement of said handle for moving said switch operating means to respectively open and close said switch upon movement of said handle to its said one position and to it said other positions, h. and said bag latch resilient means connected to said switch operating means for urging at least a portion of the latter into operative relation with said handle for movement with said handle upon movement of said handle to its said one position and to its said other positions to open and close said switch.

Claim 6

In a floor care appliance, a. a body, b. a filter for receiving dirt removed from the surface being cleaned, c. a bag latch for securing said filter to said body and including resilient means to retain the latch in filter-securing position, d. a propelling handle rotatably mounted on said body for movement to one position and to other positions relative to said body, e. a motor for the floor care appliance, f. an electric switch for said motor, g. switch operating means controlled by movement of said handle for moving said switch operating means to respectively open and close said switch upon movement of said handle to its said one position and to it said other positions, h. and said bag latch resilient means connected to said switch operating means for urging at least a portion of the latter into operative relation with said handle for movement with said handle upon movement of said handle to its said one position and to its said other positions to open and close said switch.

Claim 7

In a floor care appliance as described in claim 4, and said bag latch including a movable portion which increases the force of said resilient means upon shifting said movable latch portion to its locked position relative to said filter, whereby said resilient means exerts a greater force on said switch operating means upon securing said filter to said body.

Claim 8

In a floor care appliance as described in claim 4, and said portion of said switch operating means being mounted for movement independently of said handle to control operation of said switch to its opened and closed positions.

Claim 9

In a floor care appliance, a. a body, b. means supporting said appliance body on a surface during normal operation of the appliance, c. c. a handle for propelling the appliance on said supporting means along the surface, said handle rotatably mounted on said body for movement to one position and to other positions relative to said body, d. a motor for said appliance, e. an electric switch for said motor, f. switch operating meanS controlled by movement of said handle to its said one position and to its said other positions to respectively open and close said switch, g. handle control means for releasably maintaining said handle in said one position and in said other positions, h. and lock means for preventing operation of said handle control means when said handle is in its said one position to thereby lock said handle in said one position, whereby the latter cannot move said switch operating means to shift said switch from its open position to its closed position.

Claim 10

In a floor care appliance, a. a body, b. means supporting said appliance body on a surface during normal operation of the appliance, c. c. a handle for propelling the appliance on said supporting means along the surface, said handle rotatably mounted on said body for movement to one position and to other positions relative to said body, d. a motor for said appliance, e. an electric switch for said motor, f. switch operating meanS controlled by movement of said handle to its said one position and to its said other positions to respectively open and close said switch, g. handle control means for releasably maintaining said handle in said one position and in said other positions, h. and lock means for preventing operation of said handle control means when said handle is in its said one position to thereby lock said handle in said one position, whereby the latter cannot move said switch operating means to shift said switch from its open position to its closed position.

Claim 11

In a floor care appliance as described in claim 7, and said body having means for providing acceSs to cleaner parts on said body, and said lock means including means actuated by gravity into engagement with said handle control means to prevent operation of the latter when said handle is in its said one position to thereby lock said handle in said one position whereby the latter cannot shift said switch from its open position to its closed position, said gravity-actuated means becoming operative under the influence of gravity to engage said handle control means upon tilting the appliance body relative to the surface to expose said means for gaining access to appliance parts on said body.

Claim 12

In a floor care appliance as described in claim 7, and said lock means including gravity-actuated detent means arranged to become actuated by gravity upon tilting said appliance body from its normal position on the surface to effect movement of said detent means by gravity into engagement with said handle control means to prevent operation of the latter and thereby lock said handle in said one position whereby said handle cannot shift said switch from its open position to its closed position.
