[0047] The present disclosure of a customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 is described in detail below in reference to the figures.

[0048] FIGS. 1-13 illustrate the present disclosure of a customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1.

[0049] As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 9, FIG. 11 and FIG. 12, a customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 comprises a deformable material 2 in a lumbosacral assist block 3, hip elastic straps 4, a hip stability pad 6 and a stability elastic strap 14 comprised of abdominal elastic straps 5. The deformable material can be any material which compresses and deforms when a force is applied thereto and then returns to the deformable materials' original shape when the force is removed/released from the deformable material. One type of material is foam.

[0050] The customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 is a durable exercise device that allows an individual to perform sit-ups in any desired location and on any sitting or lying surface. Since customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 is small, lightweight, wearable and easily transportable, one can exercise anywhere including at home, in an office, outdoors, in a chair, reclining chair, sofa, couch, bed, floor, on a stool or any equivalent sitting or lying device or apparatus or even in a sitting or lying device or apparatus in a medical facility in order to perform sit-ups.

[0051] The weight of the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 is in the range of one pound to two pounds. However, the weight of the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 can be less than one pound or more than two pounds.

[0052] As shown in FIG. 2 and FIG. 8, the width (w) of the lumbosacral assist block 3 is designed to match the waist width of a person/user. Therefore, the width of the lumbosacral assist block 3 is therefore in the range of twelve inches to twenty-four inches. However, the width of the lumbosacral assist block 3 can be less than twelve inches or more than twenty-four inches. Preferably, the width of the lumbosacral assist block 3 is fifteen inches.

[0053] As shown in FIG. 1 and FIG. 11, the depth (d) of the lumbosacral assist block 3 is designed to provide stability to the user when performing sit-ups. Therefore, Applicant has found that the depth of the lumbosacral assist block 3 is in the range of four inches to eight inches. Preferably, the depth of the lumbosacral assist block 3 is five inches.

[0054] As shown in FIG. 8 and FIG. 11, the height (h) of the lumbosacral assist block 3 is critical. The height of the lumbosacral assist block 3 is designed to prevent injuring the back and spine while performing sit-ups. Therefore, Applicant's customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 has solved the problem of preventing injury to the back and spine while performing sit-ups by having the height of the lumbosacral assist block 3 being the same height of a user's sacrum. Therefore, the height of the lumbosacral assist block 3 is in the range of four inches to seven inches. Applicant has discovered the height of the lumbosacral assist block 3 being six inches is the most effective height in the prevention of injuring the back and spine while performing sit-ups. Therefore, the height of the lumbosacral assist block 3 being less than three inches or more than eight inches will not support the vertebra L5 of FIG. 7 and therefore, will not prevent injury to the back and spine while performing sit-ups.

[0055] Also, the lumbosacral assist block 3 is made from a non-slip material in order to prevent the lumbosacral assist block 3 from moving on the floor or other surface when the user performs sit-ups with customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1. The non-slip material can be a polymer, any textured material or any textured coating on a material. Some specific type of polymers can be polyethylene terephthalate (PET) and polyvinyl chloride (PVC). Also, other types of polymers can be used as a non-slip material. The textured material can include ridges, burrs or any manufacturing designed geometrical or polygonal shapes in the material which creates a non-slip surface. The non-slip material of the lumbosacral assist block 3 can be made from manufacturing processes such as sewing, spinning or equivalent methods or processes.

[0056] The lumbosacral assist block (L SAB) 3 is customizable and/or adjustable as shown in FIG. 12. A means for adjusting the height of the lumbosacral assist block (L SAB) 3. The means of the lumbosacral assist block 3 being customizable and/or adjustable is by having the lumbosacral assist block 3 being made from an elastic and/or expandable and contractable material such as nylon, spandex, Lycra™, elastane, rubber core yarn or equivalent expandable and contractable material or device. Additionally, the lumbosacral assist block (L SAB) 3 being customizable and/or adjustable is by the means of the material of the lumbosacral assist block 3 is provided with corrugations wherein the corrugations of the material allows the lumbosacral assist block to expand and stretch out the corrugations within the material so a large foam 2 can installed within the lumbosacral assist block 3 and/or wherein the corrugations of the material allows the lumbosacral assist block 3 to shrink and decrease in length/height so a smaller foam 2 can installed within the lumbosacral assist block 3. Another means of the allowing the lumbosacral assist block (L SAB) 3 to be customizable and/or adjustable is the lumbosacral assist block may be comprised or composed of Velcro™ or Velcro™ straps in order to allow the lumbosacral assist block 3 to be enlarged (expand in the vertical/height direction) and/or shrink/decrease (in the vertical/height direction).

[0057] Also, all of the above means of allowing the lumbosacral assist block (L SAB) 3 to be customizable and/or adjustable allows for different and varying vertical height foams 2 to be installed within the lumbosacral assist block (L SAB) 3. Each one of the above means of allowing the lumbosacral assist block (L SAB) 3 to be customizable and/or adjustable solves the problem of being able to use the same customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 with uses of different heights and/or different sacrum heights. For example, since the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 is customizable and/or adjustable, if a user has a four inch sacrum then a four inch foam 2 can be inserted into the lumbosacral assist block (L SAB) 3 in order to have the same height as the users sacrum and if a user has a six inch sacrum then a six inch foam 2 can be inserted into the lumbosacral assist block (L SAB) 3 in order to have the same height as the users sacrum and therefore, different height users can use a single (i.e. the same) customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 where the lumbosacral assist block (L SAB) 3 will have the same height as the users different sacrum heights. Also, because of the means of allowing the lumbosacral assist block (L SAB) 3 to be customizable and/or adjustable, the elastic expandable and contractable material, the corrugations of the material and the adjustable Velcro™ or Velcro™ straps of the lumbosacral assist block (L SAB) 3 are designed such they can apply a given force to a single foam 2 material provided inside the lumbosacral assist block (L SAB) 3 so that the height of the lumbosacral assist block (L SAB) 3 can be increased or decreased in height due to the force acting upon the foam 2 so the foam 2 is either decreased (i.e. vertically deformed) in height or is increased (i.e. a low force on the foam so the foam expands) in height so the same customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 can be used by different users which have different heights and/or have different sacrum heights and the lumbosacral assist block (L SAB) 3 of this same customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 will have the same height as the sacrum heights of the different users.

[0058] A zipper 7 is made in the bottom of the lumbosacral assist block 3 as shown in FIG. 4, FIG. 6 and FIG. 10. The zipper is made to extend along the entire bottom length and in the middle of the lumbosacral assist block 3 in order to easily insert or remove the foam 2. However, the zipper 7 may be made to extend only along a portion of the bottom length of the lumbosacral assist block 3 and/or can be made to extend from one corner 8 to another corner 8 of the bottom part of the lumbosacral assist block 3. Flaps 10 partially cover the zipper 7 in order to protect the zipper 7 from being damaged while performing sit-ups with the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1. The flaps 10 may completely cover the zipper 7 providing protection of the zipper while a user performs sit-ups with the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1.

[0059] As shown in FIG. 1, FIG. 2 and FIG. 12, a lumbosacral pad 11 is attached to and at a front top part of to the lumbosacral assist block 3 and is located at a lumbosacral angle θ. Also, the lumbosacral pad 11 is located on a lumbar surface 12 (the top part of the lumbosacral assist block 3). The lumbosacral angle θ is a critical angle of the lumbosacral assist block 3 since the lumbosacral angle θ solves the problem of preventing injury to the back and spine when performing sit-ups because the lumbosacral angle θ of the lumbosacral assist block 3 is designed to be located at a position which the vertebra L5, as shown in FIG.7, contacts the lumbosacral assist block 3 when performing sit-ups with the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1. The lumbosacral angle θ being 90 degrees was found to provide the best support for the vertebra L5 when performing sit-ups with the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1. In certain situations, the lumbosacral angle θ can be designed in the range of 65 degrees to 110 degrees. The lumbosacral pad 11 is sewn, glued, velcroid or equivalently attached to the lumbosacral assist block 3.

[0060] As shown in FIG. 12, the lumbosacral assist block 3 is made to fit the user's specific anatomic height, size and shape of the sacral bone. That is the distance between point number 1 (the coccygeal) and point number 2 (the sacral) in FIG. 12, which is the height of the human sacrum. Also, the hip stability pad 6 is made to fit the user's size and shape of the ischial bones, which is the distance between point number 1 (the coccygeal) and point number 3 (the ischial). A user will measure the sacral vertical distance between the coccygeal (point number 1) and the sacral (point number 2 and examples of this measured distance can be 5, 6, 7, 8 or 9 inches but can also be smaller or larger than these values. The lumbosacral assist block 3 of the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 will match that exact number of this measured distance and will be customizable to fit the anatomical shape and size of the sacrum bone of the user exactly just like a shoe is customizable to fit a foot. Similarly, the user will measure a horizontal ischial distance between the coccygeal (point number 1) and the ischial (point number 3) and examples of this measured distance can be 2, 3 or 4 inches but can also be smaller or larger than these values. The horizontal the hip stability pad 6 will match exactly that number of this measured distance and will be customizable to fit exactly the size and shape of the ischial bones of the user just like a shoe is customizable to fit a foot. The hip stability pad 6 has a spacing from the center in the range of 2.5 inches to 3.5 inches on each side of the center of the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 in order to support two ischial bones of the user.

[0061] The foam 2 is preferably rectangular shaped in order to provide the user easy and safe sit-up cycles. However, the foam 2 many be any geometric shape or polygonal shape so as long as when the foam 2 is inserted into the lumbosacral assist block 3, the height of the lumbosacral assist block 3 is the same height of a user's sacrum and the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 maintains the user's back fifteen degrees above a horizontal plane of the floor when preforming the sit-up exercises.

[0062] The foam 2 can be a memory foam and can be a foam that consists mainly of polyurethane and may also have additional additives which increases the foams viscosity and density. The foam 2 can be a viscoelastic polyurethane foam or a low-resilience polyurethane foam (LRPU). The foam cells are open, effectively creating a matrix through which air can move. Newer foams may recover more quickly to their original shape. The foam 2 can be the foam H-40 and H-50 manufactured by the Graco corporation.

[0063] The foam 2 is installed within a lumbosacral assist block (L SAB) 3.

[0064] Additionally, various additives can be added or blended into the foaming material as necessary. For example, a coloring agent such as a pigment or the like, a chain extender, a filling material such as calcium carbonate or the like, a flame retardant, an antioxidant, an ultraviolet absorbing agent, a light stabilizer, a conductive substance such as carbon black or the like, and an antibacterial agent or the like can be blended in. The blending amount of the various additives is appropriately regulated according the different user's size, weight or other users place of use or needs.

[0065] As shown in FIG. 1, FIG. 2 and FIG. 3, the lumbar surface 12 of the lumbosacral assist block 3 has a stability elastic strap 13 comprised of abdominal elastic straps 5. The stability elastic strap 13 is sewn, glued, velcroid or equivalently attached to the lumbar surface 12 of the lumbosacral assist block 3. The stability elastic strap 13 is made from an elastic material such as rubber, latex, or other flexible material that can return to its original shape after being stretched or extended when force is released.

[0066] The abdominal elastic straps 5 are formed at end portions of the stability elastic strap 13 such that the stability elastic strap 13 is attached to the lumbar surface 12 of the lumbosacral assist block 3 but the abdominal elastic straps 5 are free to be moved around since the abdominal elastic straps 5 are not fixedly secured to the lumbar surface 12 of the lumbosacral assist block 3. The abdominal elastic straps 5 wrap around a user's waist when performing sit-ups with the assisted abdominal sit-up device 1 and provides the lower back of the user being in constant and in direct contact with the lumbosacral assist block 3. The length of each of the abdominal elastic straps 5 are in the range of six inches to twelve inches. However, in some desired situations each of the abdominal elastic straps 5 can have a length less than six inches or more than twelve inches in order to be designed to accommodate the user's waist dimension. The abdominal elastic straps 5 comprise Velcro/Velcro design and the abdominal elastic straps 5 are fastened together with the Velcro/Velcro design. However, any other system or equivalent system of attaching ends together can be used. For example, the abdominal elastic straps 5 can be attached together via a belt design, which is the same belt design used with securing pants to a person's waist.

[0067] As shown in FIG. 1, FIG. 2, and FIG. 3, the hip elastic straps 4 are attached directly to the lumbosacral pad 11 at front corner sections of the lumbosacral assist block 3. The hip elastic straps 4 are sewn, glued, velcroid or equivalently attached to the lumbosacral pad 11. The attachment of the hip elastic straps 4 may be such that the hip elastic straps 4 are directly secured to the lumbosacral pad 11 and secured to the lumbosacral assist block 3. For example, attaching the hip elastic straps 4 to the lumbosacral pad 11 with sewing stiches may be such that the sewing stiches penetrate the lumbosacral assist block 3 and therefore, the hip elastic straps 4 are directly attached to the lumbosacral pad 11 and are also attached to the lumbosacral assist block 3. The hip elastic straps 4 are made from an elastic material such as rubber, latex, or other flexible material that can return to its original shape after being stretched or extended when force is released.

[0068] As shown in the bottom part of FIG. 1, FIG. 5 and FIG. 12, a sacrococcygeal device 14 is attached to both the lumbosacral assist block 3 and a hip stability pad 6 forming an opening 16. A sacrococcygeal pad 15 is attached to the sacrococcygeal device 14. The sacrococcygeal pad 15 is critically placed in a location of the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 where the user's coccyx (tailbone) is positioned in order to provide comfort and support of the coccyx (tailbone), prevent damage to the coccyx (tailbone), as well as to signify to the user where to sit on/in the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1. The sacrococcygeal pad 15 can be adjustably and customizable positioned on the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1. The sacrococcygeal pad 15 material is a material which is soft and provides support such as a polymer, a foam, a cushion, cotton or equivalent material. Additionally, a material which is soft and provides support such as a polymer, a foam, a cushion, cotton or equivalent material is inserted within the opening 16 of the sacrococcygeal device 14 to provide lower back and spinal support to the user when performing sit-ups with the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1. The material inserted into the opening 16 of the sacrococcygeal device 14 can be a foam, cotton, a polymer or equivalent supporting material.

[0069] As shown in the bottom part of FIG. 1, FIG. 2, FIG. 3, FIG. 6 and FIG. 12, the hip stability pad 6 is connected to the lower part of the lumbosacral assist block 3. The hip stability pad 6 is sewn, glued, velcroid or equivalently attached to the lumbosacral assist block 3. A hip pad cushion 17 is attached to a top surface of the hip stability pad 6 with any one or a combination of the methods of sewing, gluing, velcroid or equivalently attached methods. Additionally, ischial supports 18 are attached directly to the hip pad cushion 17. The location of the ischial supports 18 are critical. The ischial supports 18 are located on the hip pad cushion 17 in a specific location for the purpose of supporting the two ischial tuberosity bones, also known informally as the sit bones. The spacing from the center of the ischial supports 18 is in the range of five inches to seven inches. In addition to the spacing of the ischial supports 18, the midpoint of the spacing is where the location of the sacrococcygeal pad 15 is positioned on the sacrococcygeal device 14 as shown in in FIG. 5. Also, the ischial supports 18, as shown in FIG. 12, are customizable and/or adjustable and can being moved and/or positioned on the hip pad cushion 17. The hip stability pad 6 may not contain a hip pad cushion 17 and therefore, the ischial supports 18 can being moved and/or positioned in a customizable and/or adjustable manner on the hip stability pad 6.

[0070] The ischial supports 18 are sewn, glued, velcroid or equivalently attached to the hip pad cushion 17. The attachment of the ischial supports 18 may be such that the ischial supports 18 are directly secured to the hip pad cushion 17 and secured to the hip stability pad 6. For example, attaching the ischial supports 18 to the hip pad cushion 17 with sewing stiches may be such that the sewing stiches penetrate the hip stability pad 6 and therefore, the ischial supports 18 are directly attached to the hip pad cushion 17 and are also attached to the hip stability pad 6.

[0071] As shown in FIG. 6, the bottom surface of the hip stability pad 6 is made from a non-slip material in order to prevent the hip stability pad 6 from moving on the floor or other surface when the user performs sit-ups with the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1. The non-slip material can be a polymer, any textured material or any textured coating on a material. Some specific type of polymers can be polyethylene terephthalate (PET) and polyvinyl chloride (PVC). Also, other types of polymers can be used as a non-slip material. The textured material can include ridges, burrs or any manufacturing designed geometrical or polygonal shapes in the material which creates a non-slip surface. The non-slip material of the hip stability pad 6 is made from manufacturing processes such as sewing, spinning or equivalent methods or processes.

[0072] The hip stability pad 6 and the hip pad cushion 17 are in the shape of a rectangle or a square or any other geometric or polygonal shape which a user can perform sit-ups when using the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1. Also, the hip stability pad 6 and the hip pad cushion 17 can be the same shape or have different shapes. For example, the hip stability pad 6 can be rectangular shaped and the hip pad cushion 17 can be a square.

[0073] In a similar manner, the ischial supports 18 and the sacrococcygeal pad 15 are in the shape of a circle but can be any other geometric or polygonal shape which supports the user's ischial tuberosity and coccyx bones when the user performs sit-ups when using the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1. Also, the ischial supports 18 and the sacrococcygeal pad 15 can be the same shape or have different shapes. For example, the ischial supports 18 can be triangular shaped and the sacrococcygeal pad 15 can be a circle. Also, one ischial support 18 can be triangular shaped, another ischial support 18 can be circular shaped and the sacrococcygeal pad 15 can be a rectangular or a circle.

[0092] Operation of the Customizable Anatomical Sacral-Ischial Apparatus/Assisted Abdominal Sit-Up Device

[0093] The customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 functions as a mechanical device. The customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 aims at duplicating and assisting the functionality of the lumbosacral joint, the lower back joint between vertebra L5 and vertebra S1 as shown in FIG. 7. This lumbosacral joint affects the flexion and extension of the lower back and abdominal muscles to produce the sit-up. Flexion refers to a movement that decreases an angle between two body parts. Therefore, in the context of sit-ups, flexion is decreasing/narrowing the angle between the lower abdominal muscles and the upper thighs at the groin line. Similarly, extension refers to a movement that increases an angle between two body parts. Therefore, in the context of sit-ups, extension is increasing/widening the angle between the lower abdominal muscles and the upper thighs at the groin line.

[0094] The abdominal assisted device comprises a foam 2 in a lumbosacral assist block 3. When the user extends (stretches) his/her back and abdominal muscles, the foam 2 of the lumbosacral assist block 3 will be compressed and therefore stores energy, due to the pressure exerted on the foam 2 by the lower back muscles during the extension phase of the sit-up cycle. When the user flexes his/her lower back and abdominal muscles, (to narrow the angle between the lower abdominal muscles and the upper thighs at the groin line) pressure is released from the compressed foam 2 of the lumbosacral assist block 3 to the lower back and the released pressure exerts force/pressure on the lower back assisting the rise of the lower back and assisting the lower abdominal muscle in the flexion phase of the sit-up cycle. This is similar to a personal trainer assisting the user to rise up from a recumbent position to a sitting position. This mechanical energy stored and then released from the foam makes performing the sit-up much easier.

[0095] The customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 additionally comprises hip elastic straps and abdominal elastic straps to augment the mechanical assisting value of the abdominal assisted device. During the extension phase of the sit-up cycle, the hip elastic straps become extremely stretched and therefore stores energy. When the pressure is released from the hip elastic straps during the flexion phase of the sit-up cycle, the stored energy will be released from the hip elastic straps to the user's lower back assisting the user to complete the sit-up cycle. During the extension phase of the sit-up cycle, the abdominal elastic straps keep the lumbosacral assist block in close contact with the lower back of the user. When the user's lower back rises up from the floor or another surface during the flexion phase of the sit-up cycle, the lumbosacral assist block stays in direct contact with the lower back of the user. Hence, the mechanical preservation of energy storage and energy release improves and maximizes the efficiency of the mechanical value of the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1.

[0096] The lumbosacral assist block 3 is a highly specific elastic foam block designed with a foam 2 of a specific elasticity and density that allows the block to function as a kinetic energy reservoir unit. The lumbosacral assist block 3 will store kinetic energy during the extension (stretch) phase of the sit-up cycle (a pro-gravity phase of the motion cycle). This stored kinetic energy in the compressed lumbosacral assist block 3 will be released to assist and augment the user's power to be able to initiate the abdominal flexion phase of the sit-up cycle. The abdominal flexion phase of the sit-up cycle is the most difficult phase of the sit-up cycle because the initial abdominal flexion phase of the sit-up cycle is anti-gravity in nature and requires the user to exert a lot of kinetic energy to be able to overcome gravity (that is pulling himself/herself up). Most users lack this amount of anti-gravity kinetic energy. Therefore, the customizable anatomical sacral-ischial apparatus (CUS A-S-I-A) 1 provides sufficient anti-gravity kinetic energy needed to affect the abdominal flexion phase of the sit-up cycle and the lumbosacral assist block 3 releases its stored kinetic energy and expands to assist the user in overcoming gravity and affects the abdominal flexion phase of the sit-up cycle.

[0097] The hip stability pad adapts perfectly to the anatomy of the human pelvis. The hip stability pad provides stability and cushioning during the performance of the sit-up cycle. The coccygeal support corresponds to the coccyx (tailbone) of an individual and provides cushioning and stability of the user during sit-up cycles. Ischial supports correspond to the ischial tuberosities of the user and provide cushion and stability. The use of the hip stability pad will allow optimal performance of the sit-up cycle and prevent any unnecessary loss of the kinetic energy. This will keep the sit-up cycle as mechanically efficient as possible.

[0098] When the device of FIG. 13 used by the user, the user will be supported in total body fashion while performing sit-ups. The user will have lumbo-sacral support, the thoracic, back and neck support, and feet and ankle support.

[0099] When the device of FIG. 14 is used by the user, the user will be supported in total body fashion while performing sit-ups. The user will have lumbo-sacral support, the thoracic, back and neck support, and feet and ankle support. The triangular wedge structure is placed under the flexed knee to support arthritic conditions of the knees.

[0100] When the device of FIG. 15 is used by the user, the triangular wedge structure can be placed under the user's ankles.

[0101] When the device of FIG. 17 is used to fit the space between the user's back and the upright part of the driver seat, the device provides back support during long trips.

[0102] When the device of FIG. 18 used where the central block in the device has larger dimensions in height and width to support the lower abdomen in a prone knee-chest position to facilitate a comfortable intercourse.
