This invention relates to exercise cushions and more particularly to stackable exercise cushions.
Exercise mats, pads and cushions are often used during a variety of exercise activities that are conducted on a floor surface, such as yoga, Pilates and other training workouts. For example, a user may position a cushion on a hard floor or on an exercise mat to provide a more comfortable experience during various yoga poses or stretching exercises, by providing additional support to areas of the body such as hands, elbows, shoulders, feet, hips and knees. The user may also use stackable step platforms to provide height-adjustable support for various exercises and workouts.
Many step platforms are made of hard plastics and are uncomfortable against the hands, elbows, hips and knees of the user, while many cushions are not height-adjustable. Furthermore, cushions may slip or slide on a floor surface or on an exercise mat, causing the user to slip or fall.
Thus, there exists a need for exercise cushions that are stackable, and are less prone to slipping on a variety of surfaces, such as on mats and floors.
In various embodiments, the present disclosure provides cushions for use during a variety of exercise activities that provide additional support and comfort to areas of the body of a user. The cushions are also stackable such that a user may position two or more of the cushions as described herein together so as to provide support at varying heights. Furthermore, the cushions as described herein are shaped so as to create a partial vacuum, or suction, against a surface, thereby preventing slipping or sliding of the cushion on a floor, mat or other surface.
In one aspect, the present disclosure provides a cushion comprising: a body having a height and a width, and defined by a shaped top surface and a shaped bottom surface, the shaped top surface having a side-view profile along a cross-section of the body comprising at least one concave portion and at least one raised portion adjacent to the at least one concave portion, wherein, from a top view of the body, the at least one raised portion is at a perimeter of the at least one concave portion, and the shaped bottom surface having a side-view profile along the cross-section of the body comprising at least one concave portion underneath the at least one raised portion of the shaped top surface, at least one convex portion underneath the at least one concave portion of the shaped top surface, and at least one substantially flat portion, wherein, from a bottom view of the body, the at least one substantially flat portion is at a perimeter of the shaped bottom surface, wherein the side-view profile of the shaped bottom surface has a nesting fit with the side-view profile of the shaped top surface.

Referring to
The shaped top surface 30 has a side-view profile along a cross-section of the body 20 (such as line A-A in
The shaped bottom surface 40 has a side-view profile along the cross-section of the body 20 comprising at least one concave portion 80 underneath the at least one raised portion 60 of the shaped top surface 30, at least one convex portion 90 underneath the at least one concave portion 50 of the shaped top surface 30, and at least one substantially flat portion 100. From a bottom view of the body 20, the at least one substantially flat portion 100 is at a perimeter 110 of the shaped bottom surface 40. The at least one substantially flat portion 100 is for creating a partial vacuum so that the cushion 10 may be suctioned to a surface, such as a floor or exercise mat. By creating a partial vacuum, the cushion is less likely to slip or slip on the surface during use by a user.
In various embodiments, the side-view profile of the shaped bottom surface 40 has a nesting fit with the side-view profile of the shaped top surface 30. The shaped top surface 30 is sized and designed such that the shaped bottom surface 40 is compatible to fit therein.
The side-view profile of the shaped top surface 30 may further comprise a sloping edge 75 toward the at least one substantially flat portion 100 of the shaped bottom surface 40.
In various embodiments and as is shown in
When the cushion 10 is placed on a surface, such as a floor or an exercise mat, the at least one substantially flat portion 100 of the shaped bottom surface 40 may engage with the surface. Alternatively, both the at least one convex portion 90 and the at least one substantially flat portion 100 of the shaped bottom surface 40 may engage with the surface. A partial vacuum may be created to hold the cushion 10 in place by the user pressing against the shaped top surface 30, such as at the raised central portion 120, so as to reduce the volume of space between the shaped bottom surface 40 and the surface, which causes the air between the shaped bottom surface 40 and the surface to be expelled, thereby reducing the pressure in the space. The partial vacuum is released as air leaks back into the space between the shaped bottom surface 40 and the surface. The cushion 10 as described herein is shown in use by the user in
