FIELD OF THE INVENTION

The invention generally relates to a foldable prone support for relaxation and back stretching. In particular, the invention relates to a device that allows the user to assume a position similar to the prone fetal position, often referred to as the “balasana” or “child's pose” in yoga. The device provides additional advantages over traditional methods of assuming the “child's pose” by supporting the user's body which relieves the stress caused at the point of contact between the floor and the user's feet, knees and ankles. Further, the device of the invention utilizes gravity to enhance the stretch of the user's back and spine over the traditional “child's pose” without placing the user of the device in an unnatural or uncomfortable position. A cavity is disposed for accommodating the user's face, allowing for comfortable breathing. The facial cavity supports the user's head in such a way as to align the spine while stretching. The device folds into an aesthetically pleasing cube for easy storage or for use as a support surface for sitting or as a table.

BACKGROUND OF THE INVENTION

Stress is an inevitable everyday occurrence for most people, with demanding jobs, unreasonable deadlines, family feuds, rising cost of living, etc. Advances in modern technology provide great advantages, but they bring more competition, quicker deadlines, more demanding customers and most importantly, change. People don't like changes because that means dealing with risk and “unknown,” which are main causes of stress.

There is a strong connection between stress and back pain. Stress causes a release of stress hormones, which increase the perception of pain. Stress hormones also cause the muscles to tighten up and can lead to spasms. Back and neck muscles are particularly sensitive to the effects of stress.

Muscle tension reduces blood flow to the tissues (reduced oxygen and nutrients to the tissues) which then delays healing. Adequate circulation is also necessary to flush acidic waste products (byproducts of muscular activity) from the tissues. A build up of acidic waste products in the tissues can cause fatigue and pain.

Stress in itself can cause back pain. A person with a “bad back,” e.g. a person who has scar tissue from an old injury or degenerative changes in the spine due to aging, may notice the effects of stress triggering back pain even more than someone with a healthy back. The slightest muscle tension can compress nerves and cause pain for spinal nerves that are already restricted by scar tissue or calcium deposits. Sciatica is known to occur when one is feeling stressed. Tense back muscles increase back pain, which in turn increases tensing of muscles and causes a vicious cycle of stress and back pain.

Relieving stress can reduce pain that is aggravated or caused by tense muscles. Relaxation techniques invoke the “relaxation response,” where muscles relax and blood pressure, heartbeat, and respiration decrease. There are many known relaxation techniques, including deep breathing exercises, meditation, progressive muscle relaxation, biofeedback, massage therapy, exercise and stretching.

Special equipment is needed for biofeedback and it must be taught by a professional. Biofeedback involves using machines to monitor subtle changes in the body, such as skin temperature, muscle tension, heart rate, blood pressure, etc. By monitoring subtle changes in the body's autonomic functions, a person can learn what technique works to produce the desired result.

Massage therapy is very beneficial for relaxing muscles, increasing circulation, and relieving stress. Regular massage can help manage stress and back pain. Soaking in warm water relaxes the muscles and has a calming effect.

Exercise, and aerobic exercise in particular, burns off stress hormones and increases the body's production of endorphins, which are naturally occurring chemicals that relieve pain and improve mood.

Stretching is a crucial component of any workout routine. It relieves stress and loosens tight muscles. Back stretches help to loosen the back muscles and prevent tears and other injuries. Stretching also helps to lengthen the muscles and reduce the amount of pressure placed on the spine. Good stretching exercises can improve poor posture and relieve chronic back pain. Stretches can increase flexibility and range of motion around the joints. It can also help to prevent the joints from degenerating. By relieving tension in the muscles through stretching, more oxygen flows to the muscles to increase circulation. Stretching elongates and opens up the body. Back stretches can open up the chest and allow for easier breathing. By eliminating tension in the back, stretches can drastically reduce overall stress level. Since stress is a contributing factor to most chronic illnesses, it can also improve overall health.

Many people practice yoga, which incorporates poses that increase strength and flexibility with breathing techniques to relieve stress. The “child's pose” (see below) (also known in Indian tradition as “balasana”) is a good yoga position for relaxing in when fatigued and stressed. While in the “child's pose,” the knees increase in flexibility and blood flows into the head. The “child's pose” stretches the knees and the lower back. By opening the knees, more room is created around the belly which also allows for deeper breathing.

Unfortunately, it is not easy for everyone to perform the child's pose. Because the child's pose places pressure on the knees and ankles, people who have problems with those areas must avoid performing this position if adding pillows or towels cannot alleviate discomfort.

A number of devices have been developed to stretch the back that use gravity to enhance the stretch. For example, many versions of inversion tables are available. Many users find inversion tables to be uncomfortable. Back stretching must be stored or else are an eyesore in the room in which they are set-up and used. No back stretching devices are known that can be folded into an aesthetically pleasing object having other uses.

SUMMARY OF THE INVENTION

The invention is the result of the combination of a few basic natural principles for person wellness using the natural use of gravity energy as a primary stretching tool. The invention takes its principles from the “child's pose,” a prone human body disposition that is well known in yoga, and in many other cultures with many other names. The invention achieves a device that allows a person to maintain and comfortably hold the “child's pose” while using gravity and body weight to enhance stretching.

The invention comprises a unitary foldable device made of two complementary units, such as foam block units that can be reassembled into a substantially cube shape or opened into a substantially wedge shape. When the device is in its unfolded or wedge shape position, it comprises a method of stretching the back and spine of a user who lies prone over its sloped top planar surface. Further a face cavity is provided on the body supporting top planar surface to secure the alignment of the spine in its entirety while enabling the user to breathe comfortably during performance of the stretch. None of these features require ties or belts to secure the user to the device outside of the designed supporting contour surface of the device itself.

Additionally, the secondary cube shape, folded position of the device offers alternative secondary uses for the device, as a pleasing and unusual design aspect for a back pain reliever. These and other advantages constitute a body support structure easy and safe to maneuver, easy and smart to storage.

These and other objects and advantages of the invention will be readily appreciable from the following description of the invention and from the accompanying drawings and claims.

 DETAILED DESCRIPTION OF THE INVENTION

The invention generally relates to a device designed for relaxation and back stretching. In particular, the invention relates to a device that allows the user to assume and maintain a position similar to the prone fetal position, often referred to as the “balasana” or “child's pose” in yoga without the discomfort and limitations typically incurred in this position when performed on the floor. FIG. 1A depicts a person in the “child's pose.” Further, the device can be used as a support surface for other activities, such as a massage table.

The device comprises two complementary block units, manufactured from a material suitable to support the body weight of a user. The two complementary block units may be linked by means of a hinge system in order to switch into two principal different shapes. In its folded or secondary embodiment, the device comprises an aesthetically pleasing cube shape with a flat top surface suitable as table or to accommodate a sitting person. In one embodiment, the device comprises a hinge system that can be opened to conform a substantially wedge shaped device, comprising a plurality of cavities for accommodating the user's face, thighs and knees. In its unfolded and main substantially wedge shape embodiment, the device comprises an integral top planar surface which comprises a base end located substantially close to the floor, an upper end located at the opposite side of the integral top planar surface from the base end and an integral bottom planar surface. The base end may be substantially located at floor level, or a base end vertical surface may be situated between the base end of the integral top planar surface and the integral bottom planar surface. The upper end of the integral top planar surface is to be located at the opposite side from the base end at a distance relative to a person's trunk. An upper end vertical surface is situated between the upper end of the integral top planar surface and the integral bottom planar surface. The base end vertical surface is lower in height than the upper end vertical surface such that the integral top planar surface has a slope configuration. In one embodiment, the integral top planar surface comprises a face cavity substantially toward the base end configured to accommodate the user's face and head.

The upper end vertical surface is sized at a height such that when a user lies prone over the integral top planar surface of the device with his or her head situated toward the base end, the user's body is supported substantially at the pelvic area at the edge formed by the integral top planar surface and the upper end vertical surface allowing the buttocks and thighs of the user to substantially hang from the pelvic area accommodated in such way. The upper end vertical surface may comprise a thigh cavity to accommodate the user's thighs and knees.

In one embodiment, the invention comprises a method of relaxation and stretching the back and spine of a user using the device as previously described in its unfolded position. The user lies prone over the integral top planar surface of the device such that the user's abdomen, up to the groin, is supported and gripped by the edge formed by the upper end and the upper end vertical surface. The user is supported such that his or her knees, ankles and feet do not contact the ground as in the traditional “child's pose” but together with buttocks and thighs, be subject to the force of gravity thus being allowed with further mobility, also by means of the thigh cavity, to empower the lower limb set to increase or decrease the stretch at will. At this disposition, with his or her head situated toward the base end, the user positions his or her face, face down, in a face cavity disposed in the integral top planar surface. The face cavity, which is designed to support the chin and forehead simultaneously, serves to keep the spine aligned while permitting normal breathing by the user during the stretch. The face cavity further grips the user's face preventing, head, neck and body from sliding up or down the integral top planar surface of the device.

While in this position, the force of gravity increases the stretch of the user's back by providing forces pulling in opposite directions, i.e. downward forces at both the base of the spine and at the head of the user by allowing the weight of the legs and buttocks to provide a downward force at the base of the spine (i.e., the lumbar vertebrate, sacrum and coccyx), and the head and upper body to provide a downward force in the opposing direction at the top of the spine (i.e., the cervical vertebrate). The device thus enhances and increases the stretch of the spine and back muscles and ligaments over the traditional “child's pose” while maintaining alignment of the spine.

The device can comprise a unitary unit comprising two sections or material blocks, foldable at a hinged edge. Alternatively, the device can comprise one or more separate units. In one embodiment, the device comprises one or more separate units releasably assembled to maintain the configuration of the device.

The device can be manufactured from a wide range of materials, including wood, plastic, such as polystyrene or acrylic, fiberglass, synthetic or natural foam, rubber or cork. The device may have an inner frame, or it may be solid or hollow inside. The device could be inflatable. The device may comprise a cover made of fabric, leather or plastic, such as vinyl. Ethylene vinyl acetate foam (EVA) has been found to be a good material of construction, and does not require an outer cover. The device can be constructed from a material that can be cleaned.

The width of the device is sized to be less than the distance between the user's elbows when the user's arms are extended fully at shoulder height and greater than the distance between the user's shoulder blades. The device may be manufactured in various sizes to accommodate various frame sizes for different users.
