摘要:
A first work tool arm is rotatably attached to a frame or reference structure, a second work tool arm rotatably attached to the first work tool arm, and a work tool attached to an end of the second work tool arm. An actuator and a spring are each rotatably attached to the second work tool arm and configured such that separate movement of the first work tool arm relative to the frame or reference structure and movement of the second work tool arm and work tool relative to the first work tool arm are achieved with actuation of the actuator.

A delivery tip for flowable materials with bristles or fibers extending therefrom. The tip is a cannula with a tapered outlet and features a bristle or fiber bundle with a binding restriction member that interfaces with the cannula at some point within the cannula but has a smaller cross-sectional area for flow passage than the cannula at that point. The bristle or fiber bundle extends out of the tapered outlet. The delivery tip may connect to a material reservoir with flowable material. When positive pressure is applied to the reservoir, material then will flow through the cannula, around the restriction member, into the bristles or fibers and out the outlet for distribution to a desired surface.

摘要:
A tooth brushing system adapted to simultaneously clean a set of maxilla teeth or a set of mandible teeth. The system comprises a vibration inducer, a controller for the vibration inducer, a power source and a handle adapted to enclose the vibration inducer, the controller for the vibration inducer and the power source. The system further comprises a plurality of brushes adapted to simultaneously contact the set of maxilla teeth or the set of mandible teeth, a vibration isolation plate integral with the handle and a vibration transfer plate connected to the vibration inducer and the plurality of brushes and releasably connected to the vibration isolation plate, wherein the handle is adapted to be effectively held within a hand of a user and the vibration isolation plate is adapted to isolate vibration from the set of maxilla teeth or the set of mandible teeth not contacted by the plurality of brushes.

An oral care implement is provided includes a head platform having a plurality of faces with cleaning elements extending therefrom. The oral care implement can have flexibly mounted cleaning elements extending in opposite directions. The oral care implement can include a handle and a head with tooth cleaning elements extending from fixed pods and one or more central pods suspended between the fixed pods via a bridge. The bridge may be formed from an elastomer and permit the one or more central pods to move from an initial position toward and away from the head platform during use. The one or more central pods can include first cleaning elements extending in a first direction toward the first face and second cleaning elements extending in a second direction opposite the first direction. The second cleaning elements can extend through one or more apertures in the head platform.

A cleaning assembly for substantially flat tools is described. The assembly includes a bucket-like container which mounts interior opposed horizontally oriented brushes. The brushes are affixed by their brush backs to the interior surface of the container with working ends abutting, or they may be releasably secured to this surface. Each set of brushes is contained in a parallel horizontal plane and each pair of brushes being mutually spaced vertically. The upper most pair of brushes has working ends contained in one of a pair of vertical planes, and the second set of brushes has working ends contained either a pair of vertical planes, or in a single vertical plane.
摘要:
The invention refers to a toothbrush having anti-dental plaque and anti-tartar activity, characterised in that its bristle-carrier zone (4) is misaligned to the handle (1), a first side of said handle is aligned to the relevant side of said bristle-carrier zone and the second side of said handle has an undercut (3) bounding a recessing portion (2), said recessing portion being 2 or 3 cm. long.
摘要:
An improved toothbrush with a secure grip, a more effective bristle arrangement, and a specially shaped head is disclosed. The handle is formed with opposed gripping portions, and fits securely in the hand of the brusher, facing either up or down, imparting to the user a very secure and comfortable feeling. The toothbrush has a narrow and thin head for maximum access to the oral cavity, and a novel bristle arrangement which is highly effective for the removal of plaque from teeth with manual brushing. In one embodiment, the brush head is tapered to a narrow portion, and then optionally flares out again. In another embodiment, the head is formed with a wavy profile. In yet other embodiments, the brush head may also be provided with an upwardly curved or an angled tip. The head may also have a rubberized lower portion to effectuate gum massage, a gum stimulator, and a head with visibly different utilization areas.
摘要:
A tooth brush having a head with a hard,dome shaped, machinable plastic segment extending upwardly from said head, with arrays of tufts of bristles therein, said arrays of bristles vertically oriented to present a flat upper surface.
