Currently, existing back braces and/or harnesses are designed for positioning and fall-arrest purposes during climbing, construction, and other recreational and/or industrial activities. These assistive devices do not simultaneously provide posture support in addition to their primary positioning and fall-arrest purposes. Conversely, existing back supports are designed to assist the wearer during lifting or other activities by transferring support, for example, from the lower back to the abdominal cavity, to enable the user to lift heavier weight. Other back supports brace the lumbar spine or provide spinal decompression.
Existing back braces and other devices fail to provide any type of simple, adjustable, and effective mechanism for preventing and/or correcting poor bodily form in a manner that supports the entire spinal column during nearly all ranges of motion, including proper lifting form.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.
One embodiment provides a back-brace assistive device. The back-brace assistive device may include a back-brace assembly having (a) a series of interconnected vertebrae assemblies; (b) an upper back plate assembly coupled with the series of the vertebrae assemblies; (c) a lower back plate assembly coupled with the series of the vertebrae assemblies, wherein a plurality of ball joints interconnect the series of the vertebrae assemblies with one another, with the upper back plate assembly, and with the lower back plate assembly; and (d) at least one support component extending from the upper back plate assembly, across each of the vertebrae assemblies, to the lower back plate assembly. The back-brace assistive device may also include an anchoring mechanism attached to the back-brace assembly, the anchoring mechanism configured to secure the series of the vertebrae assemblies against a spine of a user.
Another embodiment provides a system for assisting lifting movements of a user. The system may include a back-brace assembly including: (a) an articulating series of vertebrae connected between an upper back plate assembly and a lower back plate assembly; (b) a plurality of rotational joints, one of the plurality of the rotational joints positioned between each of the vertebrae, between the upper back plate assembly and an adjacent one of the vertebrae, and between the lower back plate assembly and an adjacent one of the vertebrae; and (c) two opposing support components, each extending from a first end affixed to the upper back plate assembly, through the series of the vertebrae, to a second end affixed to the lower back plate assembly, wherein when the back-brace assembly is secured along a spine of the user, a bending of the spine causes the two opposing support components to deform elastically along with the spine and to articulate each of the vertebrae relative to one another, thereby supporting a healthy lifting posture and distributing a lifting force across a substantial portion of a back of the user.
Yet another embodiment provides a method of supporting a proper lifting posture. The method may include the steps of (1) providing a back-brace assistive device comprising a back-brace assembly affixed to an anchoring mechanism configured to secure the back-brace assembly to a user's back, the back-brace assembly including: (a) a plurality of articulating vertebrae assemblies rotationally coupled between an upper back plate assembly and a lower back plate assembly; and (b) at least one support component extending from a first end affixed to the upper back plate assembly, through the plurality of the articulating vertebrae assemblies, to a second end affixed to the lower back plate assembly; (2) adjusting the back-brace assembly to fit a length of the user's back; (3) securing the back-brace assembly to the user's back via the anchoring mechanism; and (4) lifting, by the user, an object using the proper lifting posture supported by the back-brace assembly.
Other embodiments are also disclosed.
Additional objects, advantages and novel features of the technology will be set forth in part in the description which follows, and in part will become more apparent to those skilled in the art upon examination of the following, or may be learned from practice of the technology.
Non-limiting and non-exhaustive embodiments of the present invention, including the preferred embodiment, are described with reference to the following figures, wherein like reference numerals refer to like parts throughout the various views unless otherwise specified. Illustrative embodiments of the invention are illustrated in the drawings, in which:
Embodiments are described more fully below in sufficient detail to enable those skilled in the art to practice the system and method. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense.
Embodiments disclosed herein involve a back-brace assistive device used, in some embodiments, in conjunction with a harness system. As discussed above in the Background section, existing back-brace devices are primarily designed for positioning and fall assistance or prevention during various sporting or industrial activities (e.g., Exofit “exoskeleton” braces), or alternatively, they provide support transfer between various areas of the back and core to provide lift assistance and/or enable the user to lift heavier weight, rather than enforcing proper lifting form.
Embodiments of the disclosed back-brace assistive device support the user's back in a manner that encourages proper form and movement for nearly all ranges of motion, including during lifting and other activities. Embodiments employ a series of vertebrae that are interconnected through a series of ball joints, as well as one or more elastically deforming support components that connect each of the vertebrae between an upper back plate and a lower back plate to provide reinforcement and stiffness to the vertebrae. The vertebra allow the support components to evenly distribute force over the user's entire back, or at least over 75-percent of the spinal column from the lower back to the upper back. The disclosed back-brace assistive device provides a simple and light-weight design that requires neither hydraulics nor robotics.
Turning to the figures,
The vertebrae assemblies 102 serve to distribute force over a region or an entirety the user's back. Each of the vertebrae assemblies 102 may include a vertebrae body 108 and an attached vertebrae cover 110.
In this embodiment, each of the vertebrae bodies may also include a pair of notches 124. When the cover 110 is attached to form the vertebrae assembly 102, as shown in
As shown in
Also similar to the vertebrae body 108, the lower back plate 130 may include a pair of notches 138 that combine with the lower back plate cover 132 to form a pair of support channels 140 when the cover 130 is attached to the plate 130, as shown in
The series of vertebrae assemblies 102 may also couple with the upper back plate assembly 104. This coupling may occur via another ball joint 120 between the top vertebrae assembly 102 and the upper back plate assembly 104, as shown in
In one embodiment, the upper back plate assembly 104 may provide telescoping adjustment for fine tuning the overall length of the back-brace assembly 100. That is, the upper head 142 may be adjustably attached to the upper body 144 via a fine-tune adjustment bolt 146. In some embodiments, the fine-tune adjustment bolt 146 may be have a top end 148 that is affixed within the upper head 142 such that a bottom end 150 of the adjustment bolt 146 may be threaded directly into a threaded aperture 151 of the upper body 144, shown in
The upper head 142 may form two support channels 154 that align with the support channels 126 of each of the vertebrae assemblies 102 and the support channels 140 of the lower back plate assembly 106. One of the support components 128 may be inserted into the support channels 154, 126, and 140 on each opposing side of the series of the ball joints 120, where the lower end 129 of each of the support components 128 may be pinch or press secured within the support channels 140 of the lower back plate assembly 106 via one or more rotational fasteners 122 (e.g. screws) and an upper end 127 of each of the support components 128 may be pinch or press secured within the support channels 154 of the upper head 142 via one or more rotational fasteners 122, as shown in
The rigid support components 128 provide common components that connect each of the vertebrae assemblies 102 to both the lower back plate assembly 106 the upper back plate assembly 104, thereby stiffening the series of vertebrae assemblies 102 such that they cannot rotate completely freely on the ball joints 120 and enabling the individual vertebrae assemblies 102 to evenly distribute force over the majority or an entirety of the user's back. In this embodiment, the support components 128 may be carbon fiber bars that provide resistance to both forward bending (flexion) and torsional bending, but that elastically deform in those and other directions and return to their original form after deformation. In other embodiments, the support components may be springs, rods, strips, bungee cords, or any appropriate elastic material that returns to its original shape after deformation. The support components 128 may feature a low profile that doesn't interfere with other components or the wearer. In one embodiment, the support components 128 may be attached to the user's back without the vertebrae assemblies, which may provide a thermally cooler and more lightweight system.
In this embodiment, the separate belt 206 of the harness system 202 may be threaded through the belt aperture 131 formed transversely within the lower back plate 130 such that the belt 206 may be cinched about the wearer's hips. The two-part harness system 202, including the shoulder straps 204 and the belt 206 may include any appropriate existing shoulder straps and/or belt, saving the user the expense of purchasing a new or a custom harness. Alternatively, the straps and/or the belt may be custom made for the wearer and/or the particular assembly. The shoulder strap portion 204 may feature adjustable straps that fit in a manner that retains each of the vertebrae assemblies 102 flush against the user's spine during wear.
Notably, embodiments of the anchoring mechanism or harness system 202 may include any appropriate mechanism for securing the back-brace assembly 100 to the user's back. The harness may be attached to the assembly 100, as discussed above, or it may be built directly into the assembly 100. The harness may be a two-piece shoulder strap/belt combination, or it may be a single unit that functions similar to a backpack. The upper back brace assembly 104, the vertebrae assemblies 102, and the lower back brace assembly 106 may feature any appropriate modifications and/or configurations to accommodate the structure of the anchoring mechanism.
Similarly, if the user tries to lift an object such as a heavy box using only his or her core/lower back, the support components 128, in preventing the back from over-arching, encourage the user to bend down with his or her legs and use the entire body, not just the back. Finally, if the user is moving a heavy object from side to side by rotating only his or her torso, the series of vertebrae assemblies 102 combined with the support components 128 threaded therethrough, or the vertebrae system, discourages that twisting movement and instead encourages the user to move his or her entire body, not just his or her back. In this regard, the back-brace assembly provides support for nearly all ranges of motion. The device 200 may be used for additional support, encouraging proper form, and injury prevention in a variety of movement contexts, including mining, construction, forestry, warehousing, moving, residential work, and even military use. The device 200 or the back-brace assembly 100 without the harness 202, may also be used for rehabilitation purposes in the medical field.
Embodiments of the back-brace assistive device 200 provide lift assistance and posture support without the use of electronic and/or hydraulic components. In some embodiments, the back-brace assembly 100 may be used without the harness 202. For example, the back-brace assembly 100, including the interconnected vertebrae assemblies 102 and the support components 128, may be attached through a vest such as, for instance, a Kevlar vest typically worn by peace officers. In another embodiment, the harness 202 may be replaced with another component configured to secure to the back-brace assembly 100 to the user. For example, the assembly 100 may attach via a wearable fabric such as a fitted or structured shirt with hook-and-loop fastener patches (e.g., VELCRO® Brand hook and loop patches) to secure the back-brace assembly 100 along the user's spine.
Components of the back-brace assembly 100, including the vertebrae, the upper back plate, and the lower back plate assemblies 102, 104, 106, respectively, may be formed of any appropriately robust, lightweight polymer such as, for example, carbon fiber, Teflon, or any appropriate material that may be compression and injection molded, rendering the assembly lightweight in comparison to the user's other clothing and/or gear. In one embodiment, the back-brace assembly 100 may have a weight of no more than 15 pounds. In other embodiments, the assembly may weigh 5 pounds or less. The back-brace assembly 100 is also economical, as manufacturing using compression molding is relatively inexpensive and accessible, with low barriers to entry.
In one embodiment, the ball joints 120 may comprise a low-friction material, which allows the ball joints 120 to move with ease. In addition, any component that contacts the wearer when in use may be lined with memory foam such that the component provides both comfort and an optimal fit. The memory foam may be attached to the components using an adhesive, via one or more fasteners, or in any other appropriate fashion such as, for example, via VELCRO® Brand hook and loop fasteners.
In various embodiments, the back-brace assistive device 200 incorporates a variety of easily replaceable components. If one component is damaged or worn, it may be replaced without the need to replace the entire assembly. The use of high-strength, minimal, and replaceable components renders the system strong, durable, reliable, easy to assemble, and easy to maintain.
Although the above embodiments have been described in language that is specific to certain structures, elements, compositions, and methodological steps, it is to be understood that the technology defined in the appended claims is not necessarily limited to the specific structures, elements, compositions and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed technology. Since many embodiments of the technology can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
