Grooming brush

A hair brush for use on animals or people has a planar base member with two major faces, the base member being formed with a plurality of shallow recesses on one of the faces. Two of the recesses are spaced from one another by an elongate area, and the base member is formed with at least one elongate groove on the other of the major faces of the base member. The groove is opposed to and parallel with the elongate area. Plural bristle plates are seated in respective recesses in the base member, each bristle plate exhibiting a multiplicity of prongs or tines. The bristle plates are substantially rigid at room temperature, while the base member is made of a material substantially more flexible at room temperature than the bristle plates.

CLEANING DEVICES WITH SELECTIVELY FLEXIBLE OR RIGID HANDLES
20190239704 · 2019-08-08 ·

A cleaning device is provided that has a handle configured to provide flexion in a first orientation but to provide rigidity in a second orientation. In this manner, the user can use the handle in the first orientation to allow the cleaning device to flex into hard to reach places and can use the same handle in the second orientation to apply differing levels of cleaning force.

Oral Care Implement
20190239634 · 2019-08-08 · ·

An oral care implement includes a head portion. The head portion includes one or more tooth cleaning elements. The oral care implement includes a handle portion that may be coupled to the head portion. The handle portion includes a central body having a proximal portion. The proximal portion may be opposite the head portion. The handle portion may include a first appendage extending laterally outwards from a first side of the central body in a first direction and a second appendage extending laterally outwards from a second side of the central body in a second direction opposite to the first direction. The first and second appendages may be angled towards each other to form an obtuse angle therebetween (e.g., when in an unstressed state). The proximal portion of the central body may protrude from a bottom end of the first and second appendages.

20190231059 · 2019-08-01 · ·

There is disclosed a hair brush. The brush has an elongate body including a utility portion and a handle portion at opposite ends thereof and defining a longitudinal axis. The utility portion includes a back member acting as a support from which brushing protections extend, and defines a first plane and a second plane perpendicularly intersecting the first plane. The back member is flexibly movable with respect to the handle portion on the first plane and the second plane. The utility portion further includes a pair of spines arranged at opposite sides of the back member for controlling the flexible movement of the back member whereby the extent of control of movement of the back member by the spines are either limited to the movement on only the first plane or substantially more on the first plane than the second plane.

Oral care implement
10306975 · 2019-06-04 · ·

An oral care implement comprises a head portion and handle portion comprising resiliently folding appendages. The appendages extend laterally outwards from a central body of the handle portion in opposite directions. In one embodiment, the appendages may each have annular loop structures with recurvant ends coupled to the body. The head portion comprises tooth cleaning elements such as bristles. The head portion, handle portion, and bristles may be a monolithic construction of a resiliently deformable material with elastic memory. The bristles may be especially pliable and adapted for infant or toddler use. The appendages have an undeformed width preventing the young child from over-insertion into the oral cavity when at maximum span. The appendages may be folded against the body for deeper insertion into the oral cavity by an adult. The implement is configured to prevent the head portion and tooth bristles from contacting a flat surface when placed thereon.

Systems for determining brushing parameters in an electric toothbrush
11998108 · 2024-06-04 · ·

A brush head (12), an electric toothbrush (10), and a method of operating an electric toothbrush. The electric toothbrush (10) includes bristles extending from a base structure. A plurality of tufts (20) are formed as separate groups of the bristles (23) bundled together. A sensor assembly (28) is configured to generate, for each of the tufts, a signal representative of a force applied to each of the tufts. A controller (18) is configured to generate a tuft signature representing a distribution of the force applied to each of the tufts. This tuft signature may then be classified by appropriate algorithms to determine brushing parameters, such as applied pressure, angle, and the location in the user's mouth.
