Abstract

Claims (23)

1 . A hair care appliance, comprising:

a handle and a body coupled to one another at a hinge joint such that the body is movable relative to the handle between a straight configuration in which the body is aligned with a longitudinal axis of the handle, and a bent configuration in which the body extends along an axis that is transverse to the longitudinal axis of the handle, the hinge joint including a retainer separate from and snap-fit on an end of the handle, a handle hinge plate separate from the handle and the retainer, the handle hinge plate snap-fit on the end of the handle, and a body hinge plate separate from the body and the retainer, the body hinge plate snap-fit on an end of the body and juxtaposed adjacent to the handle hinge plate, the body hinge plate and the handle hinge plate rotatable around the retainer having an opening extending through a center thereof and defining an airflow path between the handle and the body.

2 . The hair care appliance of claim 1 , further comprising a fan assembly disposed within the handle and configured to draw air in through an inlet in the handle and to direct air into the body through the central opening in the handle hinge plate and the body hinge plate.

3 . The hair care appliance of claim 1 , further comprising a heater assembly disposed within the body.

4 . The hair care appliance of claim 3 , wherein the heater assembly includes wiring arranged at a periphery of the central opening extending through the handle hinge plate and the body hinge plate.

5 . The hair care appliance of claim 1 , wherein the handle includes a handle frame assembly having the handle hinge plate snap-fit thereon, and wherein the body includes a body frame assembly having the body hinge plate snap-fit thereon.

6 . The hair care appliance of claim 5 , wherein the handle frame assembly includes a first handle frame and a second handle frame coupled to one another along the longitudinal axis of the handle by at least one attachment mechanism.

7 . The hair care appliance of claim 5 , wherein the body frame assembly includes a first body frame and a second body frame coupled to one another along the longitudinal axis of the body by at least one attachment mechanism.

8 . The hair care appliance of claim 7 , wherein first body frame and the second body frame are coupled to one another via a flexible annular element arranged at an end of the body.

9 . The hair care appliance of claim 1 , wherein the hinge joint comprises a snap hinge assembly.

10 . The hair care appliance of claim 9 , wherein the retainer, the handle hinge plate and the body hinge plate form a snap hinge assembly extending between the handle and the body.

11 . The hair care appliance of claim 1 , wherein the retainer is formed from a low friction material.

12 . The hair care appliance of claim 10 , wherein the snap hinge assembly includes a gasket surrounding the retainer.

13 . The hair care appliance of claim 1 , further comprising a latch configured to maintain the body in each of the straight configuration and the bent configuration.

14 . The hair care appliance of claim 13 , further comprising a release button configured to release the latch to enable the body to move between the straight and bent configurations.

15 . The hair care appliance of claim 1 , wherein the hinge joint is configured to enable rotation of the body relative to the handle when a torque of at least about 0.1 N is applied thereto.

16 . A hair care appliance, comprising:

an elongate handle having an air inlet in a first end and an air outlet in a second end, the handle including a fan assembly disposed therein and configured to draw air into the air inlet and to direct air out the air outlet, a retainer ring separate from and snap-fit onto the second end, and a handle hinge plate separate from the elongate handle and the retainer ring, the handle hinge plate snap-fit on the second end such that the retainer ring extends through an opening of the handle hinge plate;

a body having an air inlet configured to receive air from the air outlet on the handle, and an air outlet configured to expel air from the body, the body having a body hinge plate separate from the retainer ring and the body and snap-fit thereon the body such that the retainer ring extends through an opening of the body hinge plate, the body hinge plate defining a seam-free surface that is rotatable around the retainer ring and opposite a seam-free surface on a handle hinge plate that is rotatable around the retainer ring, the retainer ring, the body hinge plate, and the handle hinge plate forming a snap hinge assembly coupling the elongate handle and the body and defining an air flow path therethrough between the air outlet on the handle and the air inlet on the body.

17 . The hair care appliance of claim 16 , wherein an amount of force required to rotate the body into an angled configuration with the handle is between about 6.2 N and 6.7 N.

18 . The hair care appliance of claim 16 , wherein an amount of force required to rotate the body into a straight configuration with the handle is between about 4.5 N to 5.3 N.

19 . The hair care appliance of claim 16 , wherein the handle hinge plate is located at a first end of the handle and the body hinge plate is located on a second end of the body, the first end of the handle opposite the second end of the body.

20 . The hair care appliance of claim 19 , wherein the handle hinge plate is coupled to at least one handle fame via a first plurality of snap-fit features and the body hinge plate is coupled to at least one body frame via a second plurality of snap-fit features.
