Strap for face mask having multiple configurations
A mask ( 100 ), such as a filtration mask, with multiple strap configurations is provided. For example, such mask might be worn in either a head strap ( 240 ) or an ear strap ( 110 ) configuration. The mask comprises two ear straps each with a connector support element ( 130 ) allowing removable attachment of a separate head strap.
1. A face mask to be worn over a user's face, the face mask comprising:
two ear straps, each configured to be worn around a corresponding ear of the user, each ear strap comprising a connector support element;
wherein:
each of the connector support elements comprises an ear base portion comprising a soft material and an aperture in a major surface of the ear base portion,
each of the ear base portions of the connector support elements comprises atop end, a bottom end, and a hollow cavity having a longitudinal length extending from the top end to the bottom end and a thickness, the hollow cavity configured to allow each ear strap to extend through the hollow cavity,
each of the ear base portions of the connector support elements is movable along a length of each ear strap for moving each of the connector support elements along the length of each ear strap, and
wherein the face mask comprises a head strap, and the connector support elements are configured for removable attachment of the head strap, thereby allowing the face mask to be worn in two configurations, wherein:
in a first configuration, the face mask is configured to be supported on the user's face by the ear straps that are worn around the user's ears, and
in a second configuration, the head strap is removably attached to the ear straps via the connector support elements, such that the face mask is configured to be supported on the user's face by the head strap;
wherein the head strap comprises a magnetic projection at each free end and is removably attachable to the ear straps using magnetic interlocking via insertion of each magnetic projection into the aperture of the respective ear base portion in the thickness direction of the hollow cavity.
2. The face mask of claim 1 wherein each of the connector support elements is curved, and wherein the soft material is configured to interface with the user's head and is comprised of a thermoplastic urethane (TPU) cushion.
3. The face mask of claim 1 , wherein the ear straps are on a corresponding side of the face mask and comprise two elastic elements.
4. A method of wearing a face mask having a head strap and ear straps attached via free ends on each side of the face mask, each ear strap comprising a connector support element to allow removable attachment of the head strap, the method comprising the following steps:
in a first configuration, supporting the face mask on a user's face by the ear straps such that the ear straps are worn around the user's ears, wherein each connector support element comprises an ear base portion comprising a soft material and an aperture in a major surface of the ear base portion;
each of the ear base portions of the connector support elements comprises atop end, a bottom end, and a hollow cavity having a longitudinal length extending from the top end to the bottom end and a thickness, the hollow cavity configured to allow each ear strap to extend through the hollow cavity,
each of the ear base portions of the connector support elements is movable along a length of each ear strap to allow reconfiguration of a location of each of the connector support elements along the length of each ear strap, and
in a second configuration, removably attaching the head strap to each ear strap via the connector support elements, such that the face mask is supported by the head strap;
wherein the head strap comprises a magnetic projection at free ends and is removably attachable to the ear straps using magnetic interlocking via insertion of each magnetic projection into the aperture of the respective ear base portion in the thickness direction of the hollow cavity.
5. The method of claim 4 further comprising detaching the free ends of each ear strap from the face mask.
