Abstract

The present invention is concerned with a hair fastener. The hair fastener has a first hair claw member and a second hair claw member for accommodating and securing a log of hair therebetween, a first hinge positioned between and pivotably connecting respective rear ends of the first and second claw members together for controlling relative movement thereof, a first handle connected to a rear end of the first claw member, and a second handle pivotably connected to a rear end of the second claw member, and a lock including a first projection extending from the first handle and a second projection extending from the second handle in that the first and second projections are pointed towards, engageable with and lockable against each other.

Dependent claims

A hair fastener comprising:

a first hair claw member and a second hair claw member for accommodating and securing a lock of hair therebetween,
a first hinge positioned between and pivotably connecting together rear ends of the first and second claw members for controlling relative movement thereof, wherein the first hinge includes a first pin defining a first axis about which the first and second claw members pivot,
a first handle defining an inwardly facing surface and fixedly connected to the rear end of the first claw member the inwardly facing surface of the first handle abutting the rear end of the first claw member,
a second handle defining an inwardly facing surface and pivotably connected to the rear end of the second claw member by a second pin defining a second axis with the inwardly facing surface of the second handle engaging the rear end of the second claw member, wherein the second handle is provided with a bay at the inwardly facing surface at which the rear end of the second claw member engages and to which the second claw member is pivotably connected, and wherein the inwardly facing surface of the second handle is convex such that a cavity is provided between the rear end of the second claw member and the inwardly facing surface of the second handle at the bay thus allowing pivotable movement of the second claw member with respect to the second handle member,
a lock, including a first projection extending from a distal end of the inwardly facing surface of the first handle and a second projection extending from a distal end of the inwardly facing surface of the second handle in that the first and second projections are pointed towards and engageable with each other, the first projection defining a plurality of recesses along its length and the second projection defining a protrusion for engaging in one of the recesses,
wherein:
the hair fastener is adapted to assume a first configuration in which the protrusion is engaged and locked in one of the recesses whereby fastened hair positioned between the first and second hair claw members does not move or expand the first and second claw members relative to each other, and a second configuration in which the protrusion, on depression of the second handle relative to the first handle, is disengaged from said one of the recesses of the first projection whereby the first and second claw members are movable away from each other thus releasing hair positioned therebetween, and
the extent to which the first and second claw members are positioned and maintained with respect to each other is dependent on the particular recess at which the protrusion engages and locks in.

A hair fastener comprising:

a first hair claw member and a second hair claw member for accommodating and securing a lock of hair therebetween and hingedly and pivotably movable about a first axis for controlling relative movement thereof,
a first handle fixedly and immovably connected to the rear end of the first claw member such that movement of the first handle causes simultaneous movement of the first claw member,
a second handle pivotably and movably connected to the rear end of the second claw member via a hinge such that the second handle and the second claw member are pivotably movable with respect to each other to some extent,
a lock for locking the first handle and the second handle in a closed configuration when hair is secured therebetween including a first projection extending from the first handle and a second projection extending from the second handle in that the first and second projections are pointed towards and engageable with each other, the first projection defining a plurality of recesses along its length and the second projection defining a protrusion for engaging in one of the recesses,
wherein:
the hair fastener is adapted to assume a first configuration in which the second hinge biases the protrusion axially towards one of the recesses, whereby the protrusion is engaged and locked in said one of the recesses and fastened hair positioned between the first and second hair claw members do not move the first and second claw members relative to each other.
