CROSS-REFERENCES TO RELATED APPLICATIONS
This application is a continuation-in-part of U.S. patent application Ser. No. 15/246,806, entitled “PORTABLE MULTI-FUNCTIONAL UPRIGHT BODY STRETCHING APPARATUS,” filed on Aug. 25, 2016, which is incorporated herein by reference in its entirety.


BACKGROUND
Technical Field
This disclosure generally relates to an apparatus and method for stretching and exercising a human body. More particularly, this disclosure relates to an apparatus for gravity-assisted stretching of a human body, particularly upright stretching of at least a portion of the user's torso, including one or more lumbar muscles and muscles of pelvic region of the user. This disclosure also relates to a method of manufacturing the apparatus for gravity-assisted stretching. Moreover, this disclosure concerns a method of using the apparatus for gravity-assisted upright stretching of at least a lower back of the user and decompression of one or more herniated discs of the user.
Description of Related Art
The approaches described in this section could be pursued, but are not necessarily approaches that have been previously conceived or pursued. Therefore, unless otherwise indicated herein, the approaches described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.
Today, the market offers a numerous devices for stretching a human body, particularly devices for stretching a lower back of human body. These devices can be mechanical or electromechanical and employ various methods for stretching and exercising their users. Some of the devices use the concept of weight resistance, while others can use plyometric resistance or gravity assistance in implementing their stretching therapy functions.
One of most common devices for stretching is an inversion therapy device. The inversion therapy device operates by inverting the human body of the user and suspending him in an upside down position for a predetermined period. In this position, the spine and related muscles can be unloaded, relaxed, and stretched to achieve positive treatment effects. Unfortunately, the inversion therapy devices are uncomfortable and difficult to operate, especially for those who suffer from overweight. Moreover, oftentimes, the inversion therapy devices can be dangerous or even harmful for the users.
While in an upside down position, the heart of the user slows down, while the blood pressure is increased. These effects can cause the heart to move blood through the body at a force greater than it is used to do. People suffering from hypertension or other heart-related disorders may develop unwanted medical conditions while using the inversion therapy device. For example, the inversion therapy devices can cause a stroke for people with hypertension. It was also found that the inversion therapy causes elevated pressure in the eyes and exacerbates such conditions as glaucoma or retinal detachment. In addition, the inversion therapy devices can also increase a pressure in an inner ear, which may cause discomfort or aggravate ear-related health problems.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
Introduction
The present teachings generally relate to an apparatus for gravity-assisted stretching of at least a portion of a user's torso. Particularly, the apparatus is configured to enable stretching one or more lumbar muscles or one or more muscles of a pelvic region of the user. The apparatus is also configured to provide decompression of one or more herniated discs in the lower back of the user. The apparatus includes a body holder that can be affixed to a frame or any other suitable assembly. The frame can be arranged on a ground, floor, wall, ceiling, or any other non-movable structure. The body holder is generally configured to hold an upper portion of user's torso such as the lower portion of the user's torso hangs and is stretched by a gravity force. The concept of the apparatus is similar to the manner how a human holds a curved bottle in his hand.
The body holder is configured to at least partially “wrap” the upper body of the user and hold it while the user is relaxing muscles and stretching his torso using gravity. The user can control the apparatus to adjust a tilt of the body holder and his positions. The relaxed lumber muscles permit the user to stretch the spine and decompress discs in an upright position. The apparatus can enable stretching at different spinal axis angles. For example, the user can set a tilted position in a range from about 0 degrees to about 90 degrees relative to a ground level. Different angles and combinations of gravity help to decompress herniated or ruptured discs thereby releasing a pinched nerve in the lower back.
The instant apparatus can be used for therapy purposes and for body exercising purposes. The apparatus can help improving a posture, blood flow, and provide a relief from back pain. Because the user is in control of the apparatus and all movements, the user is also in control of exact positioning of his body. Thus, the apparatus is more effective, easier, and safer to operate than known prior art devices.
The following detailed description of embodiments includes references to the accompanying drawings, which form a part of the detailed description. Approaches described in this section are not prior art to the claims and are not admitted to be prior art by inclusion in this section. The drawings show illustrations in accordance with example embodiments. These example embodiments, which are also referred to herein as “examples,” are described in enough detail to enable those skilled in the art to practice the present subject matter. The embodiments can be combined, other embodiments can be utilized, or structural, logical and operational changes can be made without departing from the scope of what is claimed. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope is defined by the appended claims and their equivalents.
For purposes of this patent document, the terms “or” and “and” shall mean “and/or” unless stated otherwise or clearly intended otherwise by the context of their use. The term “a” shall mean “one or more” unless stated otherwise or where the use of “one or more” is clearly inappropriate. The terms “comprise,” “comprising,” “include,” and “including” are interchangeable and not intended to be limiting. For example, the term “including” shall be interpreted to mean “including, but not limited to.”
Additionally, all ranges provided herein include the upper and lower values of the range unless explicitly noted. For example, the term “about” shall mean a reasonable deviation of a value accompanying this term. If it is not specified otherwise, the term “about” may refer to a variation of 10% from an indicated value. In the case of a range of values, the term “about” may refer to a 10% variation from both the lower and upper limits of the range.
Moreover, it shall be understood that when an element is referred to as being “on” or “connected” or “coupled” to another element, it can be directly on or connected or coupled to the other element or intervening elements can be present. In contrast, when an element is referred to as being “directly on” or “directly connected” or “directly coupled” to another element, there are no intervening elements present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” and so forth). Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like may be used to describe an element or feature's relationship to another element(s) and/or feature(s) as, for example, illustrated in the drawings. It shall be appreciated the spatially relative terms are intended to encompass different orientations of the apparatus for stretching or its elements in use in addition to the orientation depicted in the figures. For example, if the apparatus for stretching or any of its components in the drawings is turned over, elements described as “below” and/or “beneath” other elements or features would then be oriented “above” the other elements or features. The apparatus for stretching or its components may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The term “pivot” shall be construed to mean any device or mechanism that provides pivoting motion and which movably (rotatably) connects two or more elements. The term “pivot” shall also encompass such mechanisms as joints, hinges, coupler, junctures, knuckles, links, and so forth. All these terms can be used interchangeably and mean the same. The term “pivotally” shall be construed to mean connection of two or more elements using one or more pivots.
The term “user” shall be construed to mean any individual, human, or animal using the apparatus for stretching according to any embodiment described herein. The term “user” shall also encompass a patient, client, customer, and the like.
Example Embodiments
Now, exemplary embodiments are described with reference to the drawings. The drawings are schematic illustrations of idealized example embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques or tolerances, are to be expected. Thus, example embodiments discussed herein should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing.
FIG. 1 shows a front view of an apparatus 100 for stretching according to one example embodiment. FIG. 2 shows a side view of the same apparatus 100. FIG. 3 shows the side view of the apparatus 100 as in FIG. 2 and also shows a user 305 using the apparatus 100. FIG. 4 shows a back plan view of the apparatus 100 for stretching. FIG. 5 shows a front view of the apparatus 100 for stretching which includes a padded cushion according to one example embodiment.
As shown in these drawings, the apparatus 100 includes a body holder 105 and a support device such as a frame 110. It should be understood that the body holder can be of the shape other than that shown in the drawings. For example, the body holder can have a shape or design of an upper garment such as a shirt (with sleeves or sleeveless), a blouse (with sleeves or sleeveless), a jacket (with sleeves or sleeveless), a t-shirt (with sleeves or sleeveless), or any other garment or wearable structure having an ergonomic shape to receive the user's upper body. The upper garment can be made of hard and/or durable materials such as polymers or fiberglass or any other materials like metal, polymer, fiberglass, heavy-duty synthetic fabrics, cotton, or any combinations thereof. Furthermore, the body holder can have a shape or design of an upper garment and be affixed to any suitable assembly or hanged directly by ropes, cables, wires, or chains. The upper garment can be made of hard and/or durable materials such as polymers or fiberglass or any other materials like metal, polymer, fiberglass, heavy-duty synthetic fabrics, cotton, or any combinations thereof.
Although the embodiments discussed below provide that the body holder 105 is connected to the frame 110, it should be understood that the body holder 105 can be directly or indirectly connected to the support device of other types. For example, the support device can include a piece of furniture such as a table (including a surgical table), a chair, and a bench. In some embodiments, the support device can include a ball (including a ball joint), a part of a building (e.g., a wall, floor, ceiling, doorframe, etc.), at least a part of sports or fitness equipment, and so forth. In yet further embodiments, the support device can include one or more ropes, cables, wires, beams, or chains utilized to couple the body holder 105 to any suitable structure (e.g., a portion of a building such a ceiling or doorframe).
The body holder 105 can be removably attached to the frame 110. In some embodiments, the body holder 105 can be pivotally (or rotatably) attached to the frame 110. In yet more embodiments, the body holder 105 is directly connected to the frame 110. In other embodiments, the body holder 105 is indirectly connected to the frame 110 via one or more intervening elements or devices, such as a tilt adjusting device. The frame 110 can be arranged on a floor or a ground. In other embodiments, however, the frame 110 can be configured to be secured to a wall, ceiling or any other structure or constructional element of a building. In other embodiments, however, the body holder 105 can be hung on one or more of the following: a band, a chain, a cable, a rope, and a beam.
The body holder 105 includes three main elements: a body support panel 115, a left arm holder 120, and a right arm holder 125. The body support panel 115 can be configured to receive at least an upper front portion of a body of a user 305. The left arm holder 120 is configured to receive at least a left arm of the user 305. The right arm holder 125 is configured to receive at least a right arm of the user 305. The left arm holder 120 is directly or indirectly connected to the body support panel 115, and, similarly, the right arm holder 125 is directly or indirectly connected to the body support panel 115. In some embodiments, the left arm holder 120 and the right arm holder 125 are pivotally connected to the body support panel 115 using one or more pivots, joints, hinges (collectively referred herein to as a “pivot” 130 as discussed above). In other embodiments, the left arm holder 120 and the right arm holder 125 are directly connected to the body support panel 115 such that the left arm holder 120 and the right arm holder 125 can resiliently extend or bend.
As shown in the drawings, the left arm holder 120 and the right arm holder 125 can provide support to arms of the user to relieve a negative pressure. In some additional embodiments, the left arm holder 120 and the right arm holder 125 may lack support of the user's arms and forearms, instead only supporting the underarms of the user.
In some embodiments, the pivots 130 can include a spring (e.g., a pull-back spring) such that the user 305 can individually place the left arm holder 120 and the right arm holder 125 onto the sides of his torso. In some additional embodiments, the pivots 130 can include at least one locking (fixing) mechanism or pins. In yet further embodiments, there can be provided additional mechanisms to mechanically or electronically move or rotate the left arm holder 120 and the right arm holder 125.
The body support panel 115 can be flat or ergonomic. For example, the body support panel 115 can have a curved surface to approximate a front part of a torso of the user. As shown in the drawings, the body support panel 115 can have a gutter-like shape with extended walls at its lower portion. The body support panel 115 can be manufactured from any of the following materials: metal, polymer, heavy-duty synthetic fabrics, fiberglass, cotton, or any combinations thereof. In certain embodiments, the body support panel 115 includes a padded cushion for comfort of the user.
The left arm holder 120 can be flat or ergonomic, meaning it may have a curved surface to approximate at least a portion of a left side of a torso of the user 305. Moreover, the curved surface of the left arm holder 120 approximates at least a portion of the left arm of the user 305 and optionally at least a portion of a left forearm of the user 305. Similarly, the right arm holder 125 can be flat or ergonomic, meaning it may have a curved surface to approximate at least a portion of a right side of the torso of the user 305. Moreover, the curved surface of the right arm holder 125 approximates at least a portion of the right arm of the user 305 and optionally at least a portion of a right forearm of the user 305. More specifically, as shown in the drawings, each of the left arm holder 120 and the right arm holder 125 has a complex shape of two connecting gutter-like elements connected substantially in perpendicular towards one another. One of the gutter-like elements partially wraps a portion of the torso's side of the user, while another gutter-like element is for holding the arms and forearms of the user 305. In further example embodiments, the left arm holder 120 and the right arm holder 125 can have different shapes, and portions having different shapes may be connected to each other at any angle. In some embodiments, both the left arm holder 120 and the right arm holder 125 can be made from any of the following materials: metal, polymer, fiberglass, heavy-duty synthetic fabrics, cotton, or any combinations thereof. In certain embodiments, both the left arm holder 120 and the right arm holder 125 can include padded cushions for the comfort of the user 305. In some embodiments, such as shown in FIG. 5, the body support panel 115, the left arm holder 120, and the right arm holder 125 can include a padded cushion 505 covering all of these elements.
In yet further embodiments, the body support panel 115 can be equipped with means for supporting the head of the user 305. For example, the body support panel 115 can include a chin holder or cervical collar provided around an upper portion of the body support panel 115.
In certain embodiments, the body holder 105 or its elements can be manufactured in different sizes to accommodate needs of people of different sizes and weights. For example, the body holder 105 or its elements can be of an extra small size, small size, medium size, large size, extra-large size, and so forth.
In certain additional embodiments, the body support panel 115, the left arm holder 120, and the right arm holder 125 can be manufactured as a single whole. In this example, the left arm holder 120 and the right arm holder 125 can be bendable and resiliently move with respect to the body support panel 115. In alternative embodiments, the body support panel 115, the left arm holder 120, and the right arm holder 125 can be provided as individual and separate elements which are configured to be directly or indirectly connected to each other, for example, as shown in the drawings.
Although the embodiments discussed below provide that the body holder 105 includes the body support panel 115, the left arm holder 120, and the right arm holder 125, it should be understood that the body holder 105 can work with or without the left arm holder 120 and the right arm holder 125.
The frame 110 includes a base 135 and an upper portion of the frame pivotally connected to the base 135 and configured to arrange and fix the upper portion of the frame in a tilted state relative to a ground level or the base 135. Particularly, the upper portion of the frame 110 includes two girders 140 pivotally connected to the base 135, a crossbar 145 fixed to the girders 140, and a tilt adjuster 150.
The base 135 can be made of a profiled metal like a metal pipe or from suitable polymer materials. The base 135 can have any suitable shape to support the upper portion of the frame. For example, the base 135 can be a U-shaped as shown in the drawings, although the base 135 can be of any other shape, including a circle, square, rectangle, and so forth. In some embodiments, the base 135 can have elements enabling the user 305 to secure the base 135 to a floor. For example, the base 135 can have one or more openings enabling to place screws or bolts through them for attaching the base 135 to the floor. Moreover, the base 135 can be provided with one or more optional pegs 155 for holding one or more weight plates.
The girders 140 can be of any suitable shape and design. The girders 140 can also refer to rods, beams, pipes, or any other frame elements. The girders 140 can be made of a profiled metal or polymer materials. The lower portions of the girders 140 are pivotally connected to the base 135 via one or more hinges 160. The hinges 160 can also refer to pivots, joints, couplers, and the like. The upper portions of the girders 140 are connected with each other via the crossbar 145.
The girders 140 can be also provided with one or more foot supports 165. Each of the foot supports 165 can include a rod for supporting a user's foot. The rod of the foot supports 165 is connected to a slider 170 for sliding along the girder 140. Each of the foot supports 165 also includes an insert 175 for inserting in one of openings 180 arranged in the girders 140 for fixing the slider 170 onto the girder 140.
In some embodiments, the body support panel 115 can be connected to the crossbar 145. Moreover, in certain embodiments, the body support panel 115 can include a support member 185 directly or indirectly connected to the frame 110 for preventing breaking the body support panel 115 when in use by the user 305. The support member 185 can be implemented from metal or polymer materials, and it can be arranged substantially between the crossbar 145 and the body support panel 115. In some embodiments, the body support panel 115 can integrate the support member 185. The support member 185 can also reinforce the body support panel 115 and prevent it damaging.
In further embodiments, the frame 110 can be provided with one or more handles 190 arranged substantially near the left arm holder 120 and the right arm holder 125 enabling the user 305 to grab the one or more handles 190 during a stretching exercise. As shown in the drawings, the handles 190 can be provided on the crossbar 145 near the left arm holder 120 and the right arm holder 125.
As shown in FIG. 4, the tilt adjuster 150 includes a rod 195, a slider 200, and a fixer 205. The rod 195 can be made of metal or polymer materials and include one or more openings. A lower portion of the rod 195 can be pivotally connected to the base 135. The slider 200 can be implemented as a hollow tube, pipe or cylinder, and configured to receive the upper portion of the rod 195. The slider is also pivotally connected to the crossbar 145. The fixer 205, such as a pin, is configured to affix the slider 200 to the rod 195 so as to exclude their relative movement. For example, the fixer 205 is inserted into at least one of the openings of the rod 195.
Thus, the tilt adjuster 150 enables to adjust and tilt the body holder 105 from about 90 degrees relative to a horizontal ground level to about 0 degrees relative to the horizontal ground level (see tilt direction 220 in FIG. 2). More preferably, however, the body holder 105 is tilted from about 60 degrees relative to the horizontal ground level to about 0 degrees relative to the horizontal ground level. In some embodiments, any tilted position of the body holder 105 can be fixed by the tilt adjuster 150 or any other device. In certain embodiments, the frame may lack the tilt adjuster 150, but the body holder 105 can be connected to the frame (or another support structure) via a pivot mechanism or a joint, which may allow the body holder 105 to tilt or rotate into any preferred position.
As shown in FIG. 4, the apparatus 100 may further include a body holder closing device 405. The body holder closing device 405 may be connected to the support device. The body holder closing device 405 may be configured in a form of a scissor grip device or a scissor grabber.
