Such components or features may optionally be included in some embodiments, or they may be excluded.

[0015] Embodiments of the present disclosure include connectors for use with straps and backplane systems in SCBA. SCBA can be used to provide compressed fresh air to users (such as firefighters, oil workers, etc.) and protect them from potentially harmful ambient air.

[0016] Referring to FIG. 1, a typical SCBA back panel 100 is shown, where the back panel 100 includes a shoulder strap 104 and a waist strap 108 attached to the back panel 100. These straps can allow users to carry the entire device on their back and waist. Additionally, the back plate 100 may include a cylinder strip 102 for fixing a cylinder of breathable gas to the back plate 100. In some embodiments, the backing plate 100 may include a hose 120 for carrying air from the cylinder. In the embodiment shown in FIG. 1, the straps 104 and 108 may be attached to the backplate 100 via slots 106 and 110, respectively. The grooves 106 and 110 may include one opening or multiple openings.

[0017] Referring now to FIG. 2, there is shown an exemplary connection between the strap 108 and the backing plate 100, where the backing plate 100 includes a plurality of slots 110, and a portion of the strap 108 passes through the slots 110. In some embodiments, the strap 108 can be folded back onto itself. In some embodiments, the strap 108 may be secured to a portion of itself. This type of connection between the strap 108 and the backplate can make it difficult for the strap to remove the backplate 100, and it may take 20 minutes or more to disconnect the strap 108 from the backplate 100. Therefore, if the user wants to remove the strip 108 to be cleaned or replaced, it may cost the user time and effort, and may require additional tools. Additionally, during removal and replacement of the strap 108, the strap 108 and/or the back plate 100 may be easily damaged, such as broken wires or pilling on the strap 108, or damage to the groove 110. In addition, the hose used in the SCBA may require additional components to hold the hose in place on the back plate and/or strap to prevent the hose from being hooked and/or damaged during use.

[0018] The applicant has developed a backplane connector that provides reliable quick connection and disconnection of the strip attached to the backplane. The connector can improve maintenance and manufacturing efficiency for the user, allowing the user to remove and replace the strap more easily.

The connector is described in detail below. The connector can be installed in the slot on the backplane. In some embodiments, multiple connectors may be used to connect multiple straps to the backplane.

[0019] Additionally, the connector may include clips or other attachments operable to secure one or more hoses of the SCBA. This design can prevent the air hose from being accidentally hooked, and the attachment of the hose can help fix the connector to the groove of the back plate, thereby reducing the change of disconnection of the connector during normal use.

[0020] Referring now to FIG. 3, an exemplary embodiment of a backplane system 300 is shown, wherein the backplane system 300 includes a shoulder plate 302, a lumbar plate 304, and a back plate 306. The shoulder plate 302 may be operable to connect to the shoulder strap 310. The waist panel 304 may be operable to connect to the waist strap 312. The shoulder strap 310 and the waist strap 312 may be part of a strap system 308, where the strap system 308 may also include other straps and/or attachments. The backplate 306 may be operable to attach to a cylinder of breathable air, which may be part of the SCBA system. In some embodiments, the shoulder plate 302 and the lumbar plate 304 can be movably attached to the back plate 306, wherein the shoulder plate 302 and the lumbar plate 304 can move relative to the back plate 306.

[0021] In the embodiment of FIG. 3, the shoulder plate 302 may include one or more slots 320 that are operable to receive one or more connectors 340. The connector 340 may be operable to be installed through and secured in the groove 320, as will be described in more detail below. In some embodiments, the lumbar plate 304 may include one or more slots 320 that are operable to receive one or more connectors 340. The connector 340 may be operable to be installed through the groove 320 and fixed in the groove 320, as will be described in more detail below. In some embodiments, the connector 340 may be operable to hold one or more hoses 330, where the hoses 330 may be part of an SCBA system.

[0022] Referring now to FIG. 4, a detailed view of the groove 320 is shown. In some embodiments, the groove 320 may include an opening 319 and a half groove 321, wherein the half groove 321 is cut into about half of the thickness of the opening 319. In some embodiments, the opening 319 may include a rectangular shape, and the half groove 321 may include a similar rectangular shape, wherein the rectangular shape of the half groove 321 may be rotated from the rectangular shape of the opening 319 by about 90 degrees. In some embodiments, the shape of the groove 320 and the connector may be different from a rectangle, such as a circle, an oval, or another shape.

[0023] The groove 320 shown in FIG. 4 may be the groove 320 in the shoulder plate 302, but the groove 320 of the shoulder plate 302 and the lumbar plate 304 may be similar to each other. Additionally, the connectors 340 installed in the groove 320 may be similar to each other. In other embodiments, the connector 340 and/or the slot 320 may vary in size. In some embodiments, the groove 320 and/or the connector 340 may be used on the shoulder plate 302 instead of the lumbar plate 304, while in other embodiments, the groove 320 and/or the connector 340 may be used on the lumbar plate 304 It does not need to be on the shoulder plate 302.

[0024] FIGS. 5A-5B show the connector 340 inserted into the slot 320. The connector 340 may pass upward through the opening 319 of the slot 320, as shown in FIG. 5A. The connector 340 may be attached to the strap 310. As shown in FIG. 5B, after the portion of the connector 340 has passed through the opening 319, the portion of the connector 340 may be rotated approximately 90 degrees. Then, the part of the connector 340 may be installed in the half groove 321 of the groove 320. In some embodiments, the connector 340 may include a spring that is operable to bias the portion of the connector 340 that is installed in the half groove toward the portion of the connector 340 that is located below the groove 320.

[0025] Referring now to FIGS. 6A-6B, cross-sectional views of the connector 340 and the groove 320 are shown. The connector 340 may include a main body 602 that is operable to fit through the opening 319 of the slot 320. The connector 340 may include a piston 606, wherein the piston 606 may be connected to the main body 602. In some embodiments, a screw 604 may be used to connect the piston 606 to the main body 602. The connector 340 may also include a base 608, where the piston 606 and the main body 602 may be operable to move relative to the base 608. In some embodiments, the connector 340 may include a screw 610 positioned to surround the piston 606, wherein the spring 610 may be positioned between a bottom portion of the piston 606 and a portion of the base 608.

[0026] In some embodiments, the connector 340 may include a cover 614 that is operable to attach to the base 608 to protect the spring 610 and the piston 606 from the external environment and movement. In some embodiments, for example, the main body 602 may include a clip-shaped member (or clip) 603 operable to be installed around a breathing air hose. In some embodiments, the clip 603 may extend through the top of the slot 602, allowing the hose 330 (shown in FIG. 3) to be held by the clip 603. In some embodiments, the body 602 may include other attachments for holding other elements of the SCBA system in place depending on the placement of the connector 340.

[0027] In some embodiments, the base 608 may be attached to the shaft 612, where the shaft 612 may attach the connector 340 to the strap 310. The strap 310 may be mounted about the shaft 612 and may be operable to rotate relative to the base 608. In some embodiments, the strap 210 can be removed and replaced, and the connector 340 can be reused.

[0028] In the embodiment shown in FIG. 6A, the main body 602 of the connector 340 has been pulled upward and passed through the opening 319 of the slot 320. The spring 610 may be compressed between the base 608 and the bottom portion of the piston 606 by the upward movement of the main body 602 (and therefore the upward movement of the piston 606).

[0029] In the embodiment shown in FIG. 6B, the main body 602 and therefore the piston 606 may have been rotated approximately 90 degrees and lowered into the half groove 321 of the groove 320. In the embodiment shown, the piston 606, the screw 604, the body 602, and possibly the spring 610 can rotate freely relative to the base 608. With the main body 602 resting in the half groove 321, the spring 610 may be uncompressed, and thus may bias the main body 602 downward toward the base 608. The spring 610 can fix the main body 602 in the half groove 321, where the main body 602 will need to be lifted upward against the bias of the spring and rotated about 90 degrees so that the main body 602 passes through the opening 319 and leaves the groove 320. This movement of lifting and rotating the main body 602 can be easily achieved by the user, but can be unlikely to occur spontaneously without the action caused by the user. The spring bias can ensure that the connector 340 does not accidentally loosen due to factors such as vibration or movement caused by the user.

[0030] The half groove 321 and the main body 602 may be similarly shaped so that the main body 602 is firmly installed in the half groove 321, but can be easily lifted away from the half groove 321 by the user. Similarly, the opening 319 may be shaped similarly to the half-groove 321 and the main body 602 so that the main body 602 is easily installed through the opening 319, but may be unlikely to slide through the opening 319 without any action caused by the user.

[0031] Referring now to FIGS. 7A-7D, a detailed view of the connector 340 is shown. As described above, the connector 340 may include a base 608, a main body 602, a piston 606 operable to be installed in the base 608 and connected to the main body 602 by a screw 604, and a shaft 612 connected to the base 608, the shaft being operable It connects the base 608 to a strap (not shown). The connector 340 may also include a cover 614 that is operable to be mounted on and protect some of the components of the connector 340. The main body 602 may include a clip 603 or another attachment operable to secure one or more elements of the SCBA system, such as a hose.

[0032] In some embodiments, the shaft 612 penetrates into an opening 708 in the base 608, and the shaft 612 may be installed through another opening 709 in the base 608. In some embodiments, the shaft 612 may include a head 613 to allow a user to insert, pass, or remove the shaft 612 as needed. For example, the shaft 612 can be removed to allow removal of the strip for cleaning or replacement.

[0033] FIGS. 7A and 7B show front and rear views of the assembled connector 340.

[0034] FIG. 7C shows the connector 340 with the cover 614 and the shaft 612 removed. Pistons 606 and 610 are shown.

The portion 706 of the piston 606 may be shaped to hold the portion 710 of the spring 610. Part of the piston 606 can extend through the base

608. It may occur when the main body 602 is promoted by the user. In some embodiments, the cover 314 may be operable to be mounted on the base

Part 708 of 608 on.

[0035] FIG. 7D shows the connector 340 with the cover 614, shaft 612, and base 608 removed.

[0036] FIG. 8 shows a cross-sectional view of the connector 340. As described above, the spring 610 can be positioned between the portion 706 of the piston 606 and the portion 713 of the base 608, wherein when the piston 606 (with the main body 602) moves upward, the spring 610 can be positioned at the portion 706 of the piston 606. It is compressed with the portion 713 of the base 608. As described above, the cover 614 may be mounted on the portion 712 of the base 608. In some embodiments, the diameter of the portion 706 of the piston 606 may be larger than the diameter of the rest of the piston 606, and thus it may be ensured that the piston 606 does not completely leave the base 608 when the main body 602 is lifted by the user.

[0037] FIG. 9 shows an exploded view of the connector 340. All elements can be seen individually. The screw 604 can be installed through the main body 602 and into the piston 606. The spring 610 may be installed on the piston 606 and installed in the bottom portion 706 of the piston 606. Part of the piston 606 may be installed into the base 608, and the cover 614 may be installed on the piston 606 and the spring 610 and attached to the base 608.
