Patent number: 6092252Abstract: A motor-driven toothbrush including a brush head disposed at an angle to the brush handle wherein the brush head partakes of rotary or arcuate motion, wherein the handle includes a flexible or articulated section permitting the brush head and an end portion of the handle to deflect with respect to the remainder of the handle as the brush head engages the teeth. The elastic section may be a flexible portion or may be a bellows-like member. The drive for the brush head extends through the elastic section and to the brush head. The flexible section permits the brush head to tilt angularly through an angle either greater or less than 90 degrees with respect to the axis of the brush handle. The brush head is attachable to a separate handle having a drive device.Type: GrantFiled: March 16, 1999Date of Patent: July 25, 2000Assignee: Trisa Burstenfabrik AG TriengenInventors: Franz Fischer, Philipp Pfenniger

Patent number: 5800367Abstract: An oral irrigator (1), with a stirrup-shaped nozzle holder (2) which encloses the teeth on both sides via two branches (3), is described. Nozzle openings (23 to 26) are arranged on the inner side of the branches (3) and are oriented at an acute angle (.beta.) to the axis of rotation (4) towards the open end (18) of the nozzle holder (2), in order to direct the nozzle jets (32), in the direction of the root (37), onto the lateral surfaces of the teeth (33).Type: GrantFiled: October 16, 1996Date of Patent: September 1, 1998Assignee: TRISA Burstenfabrik AG TriengenInventors: Ulrich P. Saxer, Franz Fischer

Patent number: 5321865Abstract: The oral hygiene device of the invention comprises an interchangeable end and a body (10) extended to take said end. The end may be either a movable one carrying a toothbrush or a fixed one (11) consisting of a nozzle designed to emit a pulsed jet of water generated by a pump fitted in the body (10). The movable end is designed to be given a linear and pivoting alternating movement by a drive mechanism (15) actuated by a motor (16) fitted inside the body (10).Type: GrantFiled: June 25, 1993Date of Patent: June 21, 1994Assignee: Trisa Burstenfabrik AG TriengenInventor: Charles Kaeser

Patent number: 4466150Abstract: At the handle of a bristle carrier or support of a toothbrush there is rotatably mounted disk-shaped indicator element. This indicator element contains a scale-like indicia or markings composed of data symbols, especially date symbols, which are distributed at an essentially equidistant spacing from one another about the circumference of the indicator element. Each data marking designates the month of a year. At the bristle carrier or support there is applied a second marking or indicia in the form of a mark which is located opposite the markings or indicia provided at the indicator element. By rotating the indicator element it is possible to align that data mark of the markings of the indicator element with the marker at the bristle carrier which is representative of the date when the toothbrush has started to be used or the contemplated date for possibly replacing such toothbrush. The indicator element can be subsequently arrested in its selected or set date indicating position.Type: GrantFiled: October 4, 1982Date of Patent: August 21, 1984Assignee: Trisa Burstenfabrik AGInventor: Alfred Jurt

Patent number: 4413199Abstract: A tooth cleaning apparatus having two housing portions is disclosed. Between bot housing portions, which are connected with one another by means of a snap connection, a rubber elastic ring is fixedly clamped. This ring is inserted into a groove at a support element, to which the drive motor is attached as well as a printed circuit board. A magnetically actuable switch is mounted to this circuit board is for turning-on turning-off the motor. This switch is activated by means of a magnetic element, which is secured at an actuation element displaceably mounted at the housing outer surface. The vibration dampening ring prevents transmission of vibrations emanating from the motor to the housing and at the same time serves as sealing element.Type: GrantFiled: August 19, 1980Date of Patent: November 1, 1983Assignee: Trisa Burstenfabrik AGInventor: Franz Fischer

Patent number: 4244076Abstract: A method of, and apparatus for, fabricating a bristle support or carrier for a brush, especially a hair brush, having pin-like bristles is disclosed. In a first method step there are produced the rows of bristle pins interconnected with one another at their rear end by means of a web. The individual bristle pin rows are retained in their position after forming the same to accomplish the next method step. In this next or second method step the bristle pins, at the region of their rear end, together with the webs, are cast in the material of the bristle support, so that the bristle pin rows are embedded in the bristle support.Type: GrantFiled: May 23, 1979Date of Patent: January 13, 1981Assignee: Trisa Burstenfabrik AGInventor: Walter Meyer

Patent number: 4167192Abstract: A circular brush having two mutually intertwined wire sections serving as a bristle carrier, wherein the bristles of the brush are fixedly clamped between the intertwined wire sections in a helical- or spiral-like manner. A tubular element coaxially surrounds the wire sections. This tubular element is provided with openings at its jacket surface or shell and through such openings there extend towards the outside the ends of the bristles.Type: GrantFiled: August 15, 1977Date of Patent: September 11, 1979Assignee: Trisa Burstenfabrik AG TriengenInventor: Franz Arnold

Patent number: 4068974Abstract: A fountain toothbrush is described which comprises a bristle carrier having bristles, a handle containing a reservoir for liquid or pasty dentifrice, a duct leading from the reservoir to the bristles, and actuating means which urge the reservoir in a direction out of the handle. A piston has a passage connected to the duct and to the interior of the reservoir and a cylinder sleeve part is provided on the reservoir into which the piston protrudes. When the piston is pushed into the sleeve part towards the reservoir, dentifrice is conveyed onto the bristles.Type: GrantFiled: July 13, 1976Date of Patent: January 17, 1978Assignee: Trisa Burstenfabrik AG TriengenInventors: Walter Meyer, Anton Bara

Patent number: 3937582Abstract: A fountain toothbrush is described which comprises a bristle carrier, a set of bristles on the carrier near one end thereof, a rigid handle connected to the bristle carrier at an end of the latter remote from the bristles, and a reservoir for liquid or pasty dentifrice in the handle, wherein the bristle carrier has a duct therethrough leading from the bristle carrier to an outlet near or between the bristles; furthermore piston means mounted on the bristle carrier, and outlet means associated with the reservoir, the aforesaid piston being sealingly guided in the outlet means and adapted for displacement in the outlet means toward and away from the reservoir, whereby dentifrice is caused to flow from the reservoir through the duct towards the bristles by a short displacement of the piston in the outlet means toward the reservoir.Type: GrantFiled: March 21, 1974Date of Patent: February 10, 1976Assignee: Trisa Burstenfabrik AGInventor: Franco Del Bon
