Abstract: In one aspect, the present invention is directed to a toilet seat lifting device (10), comprising a pneumatic system employing a piston (48) connected to the toilet seat (6), the system being adapted to lift the toilet seat (6) by applying mechanical force on the piston (48) in the corresponding direction (upwards, in the example herein), and to gradually lowering the toilet seat by gradually releasing air from the pneumatic system. The device may further comprise a valve (56), for causing a fall in air pressure in the pneumatic system, thereby causing an accelerated lowering of the toilet seat. The device may further comprise: a sensor, for sensing lowering of toilet seat (6); and a mechanism for activating flushing the toilet bowl upon detecting by the sensor that the seat has been lowered, such as a handle of a tap providing water to the flush tank (8) thereof.

Abstract: A toothbrush distal end for attachment to a handle of a mechanical toothbrush; the distal end comprising: a head; a neck having a proximal end and a distal end; a drive shaft having a driving bevelled gear fixed to distal end thereof; a brush consisting of a bristle array on a brush back plate, and a movement; the head being fixedly attached to the distal end of the neck; the neck being fixedly couplable to the handle and the drive shaft being couplable to a driving means; the neck being hollow and serving as a sleeve for the drive shaft; the drive shaft being rotatingly drivable about its axis within the neck, by the driving means; wherein the movement is situated within a cavity in the head and is connected to the brush back plate, for moving the brush back plate along an eccentric orbital path with respect to the head when driven by the driving means via the rotating drive shaft.
