A cleaning head for use with suction means particularly suitable for cleaning hard, flat and smooth surfaces, such as glass or marble walls. The cleaning head is equipped with attachments for cleansing liquid application, scrubbing, wiping and waste liquid removal in one piece and is normally closed so that no waste liquid inside the head will leak out during quiescent operating condition.

Cleaning device for hard and flat surfaces

A toy vehicle has a seat with a simulated seat belt in the form of two semi-circular parts which are able to rotate between an opened and closed position, the closed position simulating fastened seat belts. A power release push button is centrally positioned on the vehicle so that it does not exert any unbalanced force on the vehicle when it is pressed. When the seat belt is opened, the push button is captured in a raised position so that the vehicle cannot run. When the seat belt is closed, the capture is released from the push button so that is can be pushed. Thereafter, the push button is pushed, the power is released, and the toy vehicle is propelled.

Toy vehicle activated by moving body part

An inertia motor especially--but not exclusively--for a toy vehicle. A rear wheel axle extends through the housing and has a drive gear mounted thereon to turn unitarily therewith. A flywheel is rotatably mounted on the housing for spinning to store or to payout energy. First and second gear trains extend between the drive gear and flywheel. A movable control lever carries first and second movable gears, one of the movable gears being an idler mounted on and movable with a shaft which passes through a pair of oppositely disposed arcuate slots, the other movable gears being mounted on a shaft journaled in the lever arm. The arcuate slots are located so that the idler gear meshes with one of the gear trains when the lever arm is in one of its two positions. The teeth on the meshing gears dynamically pull the shaft to one end of the arcuate slots and into the one gear train when the drive gear is driving and pushing the shaft to the other end of the arcuate slots to eject the idler from the one gear train when the flywheel is driving. The journals for the shaft of the other movable gear are located on the lever arm so that the other movable gear meshes with the other of the gear trains when the lever arm is in the other of its two positions. The arcuate slots are part of molded plastic parts which may be made with the precision of the mold, thereby improving performance and reducing wear from poor tolerances used heretofore.

Inertia motors for toy vehicles

A toy vehicle has a gear box containing a clock spring which is wound by pushing the vehicle backward. A two part toggle-linkage system connects the gear box to the frame. When the clock spring is wound, the resulting spring bias urges the toggle-linkage system to one over center position which locks the gear box in order to preserve the energy stored in the wound spring. When the toggle-linkage system is pressed near its center, it moves over center to another position, which unlocks the gear box and releases the energy stored in the wound spring in order to propel the vehicle. When the vehicle is next moved backward, the toggle-linkage returns to the locked position which once again locks the gear box.
