Back support frame

CROSS-REFERENCES TO RELATED APPLICATIONS

The present application is a continuation in part of U.S. patent application Ser. No. 16/295,178, filed Mar. 7, 2019 titled “Back Support Frame”, which claims the benefit of U.S. Provisional Application Ser. No. 62/642,469, filed Mar. 13, 2018 and incorporates the disclosure of this application by reference.

BACKGROUND OF THE INVENTION

Self-Contained Breathing Apparatus (“SCBA”), which are utilized in the fire service industry typically consists of one SCBA frame/harness and a generally vertically oriented air bottle that is strapped onto the firefighters back and worn over his/her canvas turnouts. The standard SCBA design is somewhat similar to a standard SCUBA tank design. However, there is an obvious difference in the environment where these frames are used that impact users of the SCBA and the SCUBA frames. For example, while using a SCUBA tank, the human body is buoyant and is not subject to the stresses of gravity outside of water. However, when a firefighter uses a SCBA, the conditions and stresses on the firefighter can cause significant duress and injury.

Consistent use of the standard SCBA configuration can cause significant wear on the users back and spine. Specifically, injuries to the L4-L5 and L5-S1 have been reported with some frequency and can require surgery, which immobilize the firefighter and removes them from service. Presently, the standard SCBA restricts movement along the spine causing the lower back to function as the only hinge and fulcrum for movement, thus placing all the stress of the torso on the lower spine.

As such, an improved SCBA frame may be utilized that reduces injuries to firefighters to increase the quality of life that may be severely limited by the nature of a common injury attributed to firefighters by neuro surgeons and medical doctors. The current SCBA configuration contributes to and causes severe back injuries, L4, L5, S1 herniation's of the spine.

SUMMARY OF THE INVENTION

An exemplary SCBA frame may comprise a frame having more than one plate coupled together via an attachment system. The attachment system allows the plates to move relative to one another. The SCBA frame mimics the shape of the wearer's back. The SCBA frame may be configured to receive more than one air cylinder and the cylinders may be connected by standard hoses. The SCBA frame may utilize vertical oriented or horizontally oriented SCBA bottles. The SCBA frame also may receive a standard SCBA harness, breathing apparatus, and waist attachment.

In various embodiments, the SCBA frame for mounting self-contained breathing apparatus bottles horizontally such that the frame can move or articulate with the back of a user. The SCBA frame may comprise an upper plate comprising a top edge, a bottom edge, and a pair of sides; an intermediate plate comprising a top edge, a bottom edge , and a pair of sides; a lower plate comprising a top edge, a bottom edge, and, a pair of side; a first attachment mechanism coupled to the bottom edge of the upper plate and a top edge of the intermediate plate; and a second attachment mechanism coupled to the bottom edge of the intermediate plate and the top edge of the lower plate; wherein the first and second attachment mechanisms allow the upper plate, intermediate plate, and lower plate to move about the horizontal axis and torsionally in line with the user's movement. The first attachment mechanism comprises a pair of attachment mechanisms located proximate the sides of the upper plate and intermediate plate. The frame may comprise first and second attachment mechanisms having a pair of attachment mechanisms are located proximate the sides of the upper plate, intermediate plate, and lower plate.

Future developments in technology may present an opportunity for improvements in the design of the frame <b>100</b>. The SCBA bottle utilized for this design was a 3000-psi bottle with overall dimensions of 4⅜ inches in diameter and 16 inches long including the knob and gauge. The actual bottle was 13 inches long. The number of mounting plates <b>102</b> as presented is 4 plates for the SCBA frame <b>100</b> and also 4 plates for the other applications noted. The overall dimensions of the entire frame as well as the size and number of mounting plates <b>102</b> may also change. There may be as few as 3 mounting plates <b>102</b> and as many that can fit along the length of the pack, as the width of each plate may be manufactured narrower in the future. The key is that the SCBA frame <b>100</b> facilitates increased movement of the spine by that off additional points of movement over the present rigid frame designs that are currently utilized. The SCBA frame <b>100</b> design allows for the points of movement by that of the cable system attachment mechanism <b>104</b>. Hinges, Ball joints, springs, and any other material that will form a joint are contemplated and may be suitable for use. The cable system/attachment mechanism <b>104</b> allows for a move versatile joint that allows <b>360</b> degrees of movement and is of heavy enough gauge material to support axial loading of the pack and allows some “give” in not only the vertical axial loading but also lateral axial stresses. The cable system/attachment mechanism <b>104</b> may be centrally located or located at the ends of the mounting plates <b>102</b>. As shown in <figref idref="DRAWINGS">FIGS. 8A-8C</figref>, the user is allowed much more freedom of movement utilizing the SCBA frame <b>100</b> design. The SCBA frame <b>100</b> design moves with the user's back rather than being limited.

Although SCBA frame <b>100</b> design was initiated with respect to firefighting equipment it should be understood that this SCBA frame <b>100</b> design may benefit other people outside the Fire Service. As shown in <figref idref="DRAWINGS">FIG. 9</figref>, a mobility frame <b>200</b> may comprise any type of back frame utilized for hiking, hunting, back packing or even military operations can be improved with this concept of the Advance Spinal Mobility Frame. With some minor modifications, this mobility frame <b>200</b> design is fully applicable for a Back-Pack application.

The mobility frame <b>200</b> may comprise multiple generally rectangular mounting plates <b>202</b> that are coupled by attachment mechanisms <b>104</b>. In one embodiment, the mobility frame <b>200</b> comprises four generally rectangular mounting plates <b>202</b> that are coupled by attachment mechanisms <b>104</b>. The attachment mechanism <b>104</b> allows the mounting plates <b>202</b> to move relative to one another and allows the SCBA frame <b>100</b> to conform to the shape of the user's back. The attachment mechanism <b>104</b> may allow the user to move along vertically, horizontally, and torsionally.

The mounting plates <b>202</b> are similar to mounting plates <b>102</b> of but the SCBA air cylinder attachment system <b>186</b> have been removed. The mount plates <b>202</b> allow points (slot, cutouts, etc.) for securing the material and webbing that makes up the various back packs in the industry and it's done. The cable system/attachment mechanism <b>104</b> may be centrally located or located at the ends of the individual mounting plates <b>202</b>. The orientation of the cable system/attachment mechanism <b>104</b> and the mounting plates <b>202</b> would be the same regardless of whether the mobility frame <b>200</b> does or does not include the SCBA air cylinder attachment system <b>186</b>.

The width of the mobility frame <b>200</b> can be reduced to whatever the need of the pack manufacturing company may require. Many frames of the traditional one-piece vertical back pack frames are approximately <b>8</b> inches by <b>26</b> inches. The cable system/attachment mechanism <b>104</b>, slots and punch outs along with the lumbar attachments will not change.

Referring now to <figref idref="DRAWINGS">FIGS. 10-11</figref>, in various embodiments, an SCBA frame <b>300</b> that conforms with the user's spine but also utilizes a conventional SCBA bottle <b>302</b> in a vertical orientation. The SCBA frame <b>300</b> complies with all of the requirements discussed above in paragraphs <b>41</b>-<b>45</b> and is fabricated from the same material discussed above.
