Strap for face mask having multiple configurations
Embodiments relate generally to masks, such as filtration masks, with multiple strap configurations. For example, such masks might be worn in either a head strap or an ear strap configuration. Embodiments typically comprise two ear straps each with a connector support element 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 top end, a bottom end, a hollow cavity having a longitudinal length extending from the top end to the bottom end and a locking element protruding perpendicularly outward from a surface of the ear base portion, the hollow cavity configured to allow each ear strap to extend through the hollow cavity,
wherein each of the ear base portions of the connector support elements is movable along a fixed length of each ear strap for adjusting a location of each of the connector support elements along the fixed length of each ear strap,
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, and
wherein the head strap comprises a receiving element at each free end and is removably attachable to the ear straps via insertion of each locking element into an aperture of the respective receiving elements at each free end of the head strap, wherein each receiving element is a snap joint, and
wherein a direction of the insertion is transverse to the longitudinal length of the hollow cavity, posteriorly towards a rear of the user's head when the head strap is worn.
2 . The face mask of claim 1 , wherein each of the connector support elements is curved and comprises a soft material.
3 . The face mask of claim 2 , wherein the soft material is configured to interface with the user's head and is comprised of a thermoplastic urethane (TPU) cushion.
4 . The face mask of claim 1 , wherein the ear straps are on a corresponding side of the face mask and comprise two elastic elements.
5 . The face mask of claim 1 , wherein each of the receiving elements is attached to the respective free end of the head strap using a loop.
6 . The face mask of claim 1 , wherein each locking element includes a biased locking element, wherein removal of the head strap from each ear strap includes a depression of the biased locking element.
7 . The face mask of claim 1 , wherein a length of the head strap is adjustable to modify a tension of the two ear straps.
8 . 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 top end, a bottom end, a hollow cavity having a longitudinal length extending from the top end to the bottom end and a thickness, and a locking element protruding perpendicularly outward from a surface of the ear base portion, the hollow cavity configured to allow each ear strap to extend through the hollow cavity, 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 receiving element at each free end and is removably attachable to the ear straps via insertion of each locking element of the ear strap into an aperture of the respective receiving elements at each free end of the head strap, wherein each receiving element is a snap joint, and
wherein each of the ear base portions of the connector support elements is movable along a fixed length of each ear strap for adjusting a location of each of the connector support elements along the fixed length of each ear strap, and
wherein a direction of the insertion is transverse to the longitudinal length of the hollow cavity, posteriorly towards a rear of the user's head when the head strap is worn.
9 . The method of claim 8 , further comprising detaching the free ends of each ear strap from the face mask.
10 . The method of claim 8 , wherein each locking element includes a biased locking element, wherein removal of the head strap from each ear strap includes a depression of the biased locking element.
