Stretching mat
Provided is a stretching mat whereby high stretching effects are obtained relative to the conventional configuration. An air bag is provided to a stretching part for curving and protruding in a ridge shape along a front-rear direction, and transformation is possible between a gently curved state in which the air bag is deflated and a strongly curved state in which the airbag is swollen and more strongly curved than in the gently curved state. A configuration is also adopted in which air is supplied to the air bag in a state in which a portion of a body is resting on the stretching part, and the stretching part transforms from the gently curved state to the strongly curved state over time, after which the supply of air is stopped and the strongly curved state of the stretching part is maintained.
1. A stretching mat comprising:
a housing comprising a curved upper surface having a first curvature;
an airbag disposed over the curved upper surface of the housing, the airbag comprising a first surface and a second surface;
an air supplier connected to the airbag;
an air supplier controller configured to allow the air supplier to supply air to the airbag to inflate the airbag;
a control panel for receiving a user input for controlling the air supplier controller,
wherein the control panel is provided on a lateral side of the housing,
wherein the air supplier controller waits a second period of time after receiving the user input and before allowing the air supplier to supply air to the airbag,
wherein when the airbag is inflated, the first surface of the airbag has the first curvature and the second surface of the airbag has a second curvature, and
wherein the first curvature differs from the second curvature when the airbag is inflated.
2. The stretching mat according to claim 1 , wherein the second curvature has a greater degree of curvature than the first curvature.
3. The stretching mat according to claim 1 , wherein the air supplier controller maintains the inflation of the airbag for a first period of time.
4. The stretching mat according to claim 3 , wherein the air supplier controller releases air from the airbag after the first period of time has elapsed.
5. The stretching mat according to claim 1 , further comprising a vibration device that vibrates the housing, the vibration device is disposed within the housing.
6. A stretching mat comprising:
a housing comprising a curved upper surface having a first curvature;
an airbag disposed over the curved upper surface of the housing, the airbag comprising a first surface and a second surface;
an air supplier connected to the airbag, the air supplier supplying air to the airbag to inflate the airbag; and
a presser plate disposed along an entire outer peripheral of the airbag, the presser plate fixing the airbag to the curved upper surface of the housing,
wherein when the airbag is deflated, the first surface and the second surface of the airbag conform to each other,
wherein when the airbag is inflated, the first surface of the airbag has the first curvature and the second surface of the airbag has a second curvature, the first curvature being different from the second curvature, and
wherein the presser plate comprises an opening from which the second surface of the airbag protrudes when the airbag is inflated.
