Wearing tool for breathing mask, and breathing mask

A wearing tool for a breathing mask which supplies a user with gas for breathing comprising:

• a pair of connecting members each of which has a longitudinal shape and has a first end portion which is connected to the breathing mask;
• and
• a pair of frame portions, each of which is connected to a second end portion of each of the pair of connecting members;
• wherein
• each of the pair of frame portions comprises:
• a first portion having a first end connected to the second end portion of one of the pair of connecting members and adapted to be placed around the outer circumference of the ear flap of the user, and the first portion being not pressed between the ear flap and a head of the user when the user lies on the side, the entire first portion having an inner radius larger than the entire outer circumference of the ear flap;
• and
• a biasing portion which is connected to a second end of the first portion and is adapted to bias the base of the ear of the user in a forward direction of the user, and a diameter of the biasing portion being configured to be smaller than a diameter of a part of the first portion, the part of the first portion being positioned along the biasing portion;
• wherein each of the pair of connecting members has a strap and a supporting member, wherein said supporting member comprises a first plate-shape member which is fixed at the breathing mask, and a second plate shape member which is fixed at the strap, wherein the first plate-shape member and the second plate-shape member are configured to be rotatable around a rotation axis which is provided at a position on an extended line of the second region of the supporting member.

A wearing tool for a breathing mask which covers nostrils of a user and supplies pressurized gas for breathing to the nostrils comprising:

• a pair of connecting members each of which has a longitudinal shape and has a first end portion, which is connected to the breathing mask, and a second end portion at the opposite end of the first end portion, which is connected to each of a pair of fixing portions, and which is adapted to fix the breathing mask at the environs of the nostrils of the user and is adapted to pass on a cheek of the user;
• wherein
• each of the pair of connecting members has
• a strap having a longitudinal shape and being located between the first end portion and the second end portion and
• a supporting member provided on the strap, extending in the longitudinal direction of the strap, and having greater rigidity than that of the strap,
• the supporting member of said each of the pair of connecting members has
• a first region having a first width and being located to the first end portion and
• a second region extending from the first region toward the second end portion and having a second width, which is narrower than the first width, and
• the strap of said each of the pair of connecting members is adapted to pass on cheekbones of the user at a position parallel to the second region and the second region of the supporting member is adapted to pass below the cheekbones and be prevented from passing on the cheekbones;
• wherein said supporting member comprises a first plate-shape member which is fixed at the breathing mask, and a second plate shape member which is fixed at the strap, wherein the first plate-shape member and the second plate-shape member are configured to be rotatable around a rotation axis which is provided at a position on an extended line of the second region of the supporting member.

A breathing apparatus comprising:

• a breathing mask having a third width and adapted to cover nostrils and peripheral area of the nostrils of a user and supply gas for breathing to the nostrils;
• and
• a wearing tool connected to the breathing mask,
• wherein the wearing tool comprises:
• a pair of connecting members each of which has a longitudinal shape and has a first end portion which is connected to the breathing mask, and a second end portion at the opposite end of the first end portion;
• wherein
• each of the connecting members has
• a strap having a longitudinal shape and being located between the first end portion and the second end portion and
• a supporting member provided on the strap, extending in the longitudinal direction of the strap, and having greater rigidity than that of the strap,
• the supporting member further comprises
• a first plate-shape member which is fixed at the breathing mask and has a first width and
• a second-plate shape member which is fixed on the strap and has a second width,
• the first plate-shape member and the second plate-shape member are rotatably connected with each other at a rotational axis so that the first plate-shape member and the second plate-shape member are rotatable with respect to each other, and
• the rotational axis is provided at the bottom end portion of the first plate-shape member and in a direction of the second width of the second plate-shape member, and
• the position of the bottom end portion in the first width and the second width corresponds to the position of a bottom end portion in the third width of the breathing mask.
