Embodiment Construction

[0044] The drive hub 1 is collectively identified with the reference numeral 1 in FIGS. 1 a to 1 c. The hub is made from a single piece of machined metal. The hub has an upper part 2 (formed as a tube ring). The collar defines a bore for receiving a drive shaft (not shown) driven by the motor. Locking means (not shown) are securely provided for securing the hub to the drive shaft for co-rotation. Suitable locking means are known to those skilled in the art and may include, for example, dog stubs (not shown). The lower part 3 of the hub forms a generally dome-shaped cover. The side regions of the cover are machined with eight vertical planes 5 which provide an octagonal shape. Thus, the cap has an upper shoulder surface of a substantially octagonal ring extending around the upstanding tubular member. The lower surface of the cover is formed as a flat circular surface 6 . The peripheral area of ​​this surface 6 tapers according to a domed profile which extends until it int...

Abstract

A rotary work head assembly is provided suitable for connecting the drive hub (1) of a rotary floor cleaning machine (50) to a working head (10). The coupling comprises latching features associated with the hub (1) and working head (10). The latching features engage to retain the working head (10) on the hub (1) in a coaxial arrangement suitable for operation of the machine (50). To remove the working head (10), the operator tilts the working head (10) away from the coaxial position, which permits disengagement of the working head (10) from the hub (1).

Description

technical field [0001] The present invention relates to a rotary working head assembly suitable for coupling together a drive hub and a working tool. More specifically, the present invention relates to an assembly for connecting a drive hub to the working head of a rotary floor cleaning machine or treatment machine. [0002] The invention relates in particular to the field of rotary floor maintenance machines of the type having a circular or annular rotary treatment head on the underside of which is provided a working surface comprising, for example, a brush or a polishing pad, said rotary treatment head The head rotates parallel to the surface to be cleaned. The treatment can range from buffing and cleaning to severe treatments such as sanding, grinding, scouring and scarifying. Background technique [0003] Floor treating machines generally comprise one or more rotatable treatment heads, which are driven, for example, by an electric motor. Typical machines are described...
