A hair cutting appliance, a blade set for a hair cutting appliance, and to a stationary blade for the blade set. The stationary blade includes a first wall portion arranged to serve as a skin facing wall when in operation, a second wall portion at least partially offset from the first wall portion, such that the first wall portion and the second wall portion define therebetween a guide slot arranged to receive a movable cutter blade in a defined mating manner, and at least one toothed leading edge having a plurality of teeth jointly formed by the first wall portion and the second wall portion. The stationary blade is an integrally formed metal-plastic composite stationary blade. Also discussed is a blade set including an integrated foil shaving region, along with a method for manufacturing a respective blade.

A blade set assembly for a hair cutting appliance includes a stationary blade and a movable blade. The movable and stationary blades are arranged one on top the other and movable relative to each other. A guide unit is formed between the movable blade and the stationary blade, where the blades engage each other. The guide unit includes longitudinally spaced, laterally extending guideways, each defined between a stationary blade guide surface and a movable blade guide surface that overlap each other. Rolling elements are arranged at the guideways between the guide surfaces. The guide surfaces have a height extension greater than a radius of the rolling elements such that the guide surfaces overlap in a vertical direction. The guide surfaces provide for coupling in a longitudinal direction between the blades such that the guide unit provides for a set longitudinal distance for any force applied in the longitudinal direction.

Blade set assembly and hair cutting appliance

A method of manufacturing a blade set assembly, a blade set assembly, and a hair cutting appliance, wherein the method includes providing a base component including a stationary blade, providing a movable component comprising a cutter blade, providing a coupling element, the coupling element being arranged to be interposed between the base component and the movable component, providing a plastic contact bridge, arranging the stationary blade and the cutter blade at a defined relative assembly position, securing the assembly position between the stationary blade and the cutter blade, involving attaching the plastic contact bridge to one of the base component and the movable component, attaching a retaining portion of the coupling element to the other one of the base component and the movable component, and penetrating the plastic contact bridge with at least one insertion end of the coupling element.

Blade set manufacturing method, blade set and hair cutting appliance

A stationary blade for a hair cutting appliance and a method of forming the stationary blade includes providing tooth components obtained from metal material, where the tooth components are arranged in a substantially flat fashion and are at least partially tapered towards a tip end. The method further includes arranging the tooth components next to each other to form a series of spaced apart teeth, where neighboring tooth components are arranged at a distance from one another; providing a blade base acting as a support receptacle, arranged to receive the tooth components; and interconnecting the tooth components and the blade base in a direct or mediate fashion, thereby forming teeth of the stationary blade.

A hair cutting appliance (), a blade set () for a hair cutting appliance (). and to an integrally formed metal-plastic composite stationary blade () for said blade set () are described. The stationary blade () may include: a first wall portion () arranged to serve as a skin facing wall when in operation; a second wall portion () at least partially offset from the first wall portion (), such that the first wall portion () and the second wall portion () define there between a guide slot () arranged to receive a movable cutter blade (), at least one toothed leading edge () jointly formed by the first wall portion () and the second wall portion () and a plastic component () including at least one mounting element (). The toothed leading edge () includes a plurality of teeth ().

An automatic toothbrush (), including: a body () having opposed ends, a cavity () situated between the opposed ends, and an opening () situated at one of the opposed ends; an output shaft () having first and second ends () and extending through the opening such that the second end () is outside of the cavity, the output shaft having a plurality of bends () situated between the second end and the opening; and an oral cleaning tool () configured to be press fit onto that portion of the shaft which has the plurality of bends.

Shaft for an automatic toothbrush

A stationary cutting blade for a hair clipping device has a base body and a coined cutting teeth. The coined cutting teeth are spaced apart from each other, arranged on a front side of the base body, and each extend parallel to a longitudinal axis of the stationary cutting blade. A thickness ratio between the thickness of the base body and the thickness of the cutting teeth is larger than 1.1. Each cutting tooth has a substantially wedge-shaped cross-section with a scissor angle and a wedge angle, where the sum of the scissor angle and the wedge angle is smaller than 70&#xb0;.

Stationary cutting blade for a hair clipping device

The present invention relates to a hair cutting appliance and to a blade set for a hair cutting appliance including a blade set having a stationary blade constructed having a first wall portion and a second wall portion that define therebetween a guide slot, a movable cutter blade received at the guide slot, and a transmitting member configured to be engaged by a driving member, and to actuate the movable cutter blade relative to the stationary blade, wherein the movable cutter blade is laterally inserted into the guide slot, wherein the transmitting member is fed to the stationary blade in a feed direction that is different from an insertion direction of the movable cutter blade, and wherein the transmitting member is coupled to a main portion of the movable cutter blade, such that the movable cutter blade is undetachably retained at the stationary blade. The disclosure further relates to a method for manufacturing a respective blade.

A hair clipping device, including, a housing; a cutting assembly including a stationary blade and a moveable blade resiliently biased against the stationary blade, the stationary blade and the moveable blade defining a cutting plane therebetween, an eccentric transmission element including an eccentric pin protruding therefrom and arranged on a rotary driven shaft, a motor for driving the eccentric transmission element; a coupling element coupled to the eccentric transmission element for translating a movement of the eccentric transmission element into oscillatory movement of the moveable blade relative to the stationary blade; the coupling element arranged inside of a common recess formed from a first recess cut into the movable blade and a second recess cut into the stationary blade that form the common recess; wherein the eccentric transmission element engages the coupling element at at least one engagement point in the same plane as the cutting plane.
