In addition, the groove 24 includes at least one (or two in a preferred non-limiting embodiment or solution) orifice 60 extending through the bottom surface 62 of the groove 24. The size, shape, or configuration of these apertures 60 (or conduits) are defined to at least partially receive and retain the attachment extension 56 so that the contact 18 is attached to the seat portion 14 of the base member 12.

[0062] In a preferred non-limiting embodiment or solution, the attachment extension 56 includes a shaft 64, for example a cylindrical member, which has a cap 66 on its end. The cap 66 may be rounded, flat, round, spherical, or the like. In a preferred non-limiting embodiment or solution, the cap 66 is a rounded button-like component. In addition, the orifice 60 defines a conduit 68 having a ledge 70. In this embodiment or solution, the attachment extension 56 is made of a flexible, resilient or deformable material, so that the attachment extension can be compressed and squeezed into the conduit 68, wherein the cap 66 expands in the duct 68 and abuts or engages the shoulder 70 of the duct 68. This presents a "button-like" connection between the contact 18 and the seat portion 14. This removable engagement between the contact piece 18 and the seat portion 14 facilitates easy repair or replacement of the contact piece 18. For example, if the contact member 18 tears, tears, breaks, degrades, or otherwise becomes ineffective, the "button" engagement described above can be used to simply remove the contact member from the seat portion 14.

Therefore, this elongated belt 76 can be engaged with the gas tank (T) and tightened relative to the gas tank (T), for example, by using a latch/tension assembly 78 that is operatively engaged with at least a portion of the base member 12 And/or become loose. Any suitable elongated belt 76-latch/tension assembly 78 can be used without departing from the spirit and scope of the currently claimed invention. For example, the tension buckle may be attached to the bracket 72 by an intermediate spring that is fixed to a lug protruding from the bracket 72. The elongated strap 76 may be attached to the tension buckle so that when the gas tank (T) is in place against the seat frame portion 14, the tension buckle can operate to tightly wrap the strap 76 around the gas tank (T) fixed.

[0065] In another preferred non-limiting embodiment or solution, at least a portion of the contact side 16 of the seat frame portion 14 is made of a frictional or gripping, for example, "sticky" material, such as a rubber material, Elastic materials, synthetic materials, etc. In this way, the user (U) can slide the gas cylinder (T) on the contact piece 18 along the contact piece to an appropriate position. Once in place, the user (U) can use the gas tank holder device 20 (e.g., the elongated belt 76-latch/tension assembly 78) to push the gas tank (T) toward the contact side 16 of the seat frame portion 14 and Squeeze the gas tank against the contact side. At least a part of the contact side 16 is formed by using a frictional or gripping material, and after actuation or operation of the gas tank holder device 20, the gas tank (T) is held in place more firmly against the base member 12, wherein The frictional or gripping material prevents or reduces any lateral movement of the gas tank (T). Therefore, the gas tank attachment device 10 provides an advantageous "slide and clamp" function.

[0066] Referring to FIGS. 2 to 5, in another advantageous non-limiting embodiment or solution, the contact side 16 of the seat portion 14 includes a seat contact 80, or is in the form of a seat contact 80, which The seat frame contact piece is either formed on the upper surface 82 of the base member 12, or is attached to the upper surface, for example, by some interaction device 83 (see FIG. 5).

It is provided for connecting the seat frame contact 80 to the upper surface 82 of the base member 12. In this embodiment or solution, the seat frame contact member 80 is wholly or partly made of the aforementioned frictional or gripping material.

[0067] In addition, as shown in FIGS. 2-5, the seat frame contact member 80 may include a middle seat frame contact portion 84 and two side seat frame contact portions 86, all of which can be separated by a groove 14, for example. open. In addition, at least a portion of the seat frame contact member 80, the middle seat frame contact portion 84, and/or the side frame contact portion 86 may be shaped or configured to properly contact and engage the side surface of the gas tank (T). In particular, in a preferred non-limiting embodiment or solution, the seat frame contact member 80 including the middle seat frame contact portion 84 and/or the side frame contact portion 86 is provided with the above-mentioned first inclined portion 50 and straight portion 52 and/or the second inclined portion 54. This helps to promote the above-mentioned "slide and clamp" function.

[0068] In addition, by providing the middle seat frame contact portion 84 and the side seat frame contact portion 86, it is possible to effectively adapt to a variety of gas tank (T) sizes. For example, when positioning a larger diameter gas tank (T) and when the gas tank holder device 20 (such as the elongated belt 76-latch/tension assembly 78) is actuated or operated, the larger diameter gas tank (T) ) Will mainly, only or initially contact the side mount contact portion 86; when positioning the smaller diameter gas tank (T) and when the gas tank holder device 20 is actuated or operated, the smaller diameter gas tank (T) will Mainly, only or initially contact the intermediate seat frame contact portion 84. The contact points or areas of these specific structures can also be made of the aforementioned frictional or gripping materials, or coated with such materials.

[0069] In this way, a gas tank attachment device 10 for a self-contained breathing apparatus (SCBA) is provided, which helps to quickly attach the gas tank (T) to the self-contained breathing apparatus (SCBA). And quickly remove the gas tank from the back plate assembly (BP) of the ventilated breathing apparatus (SCBA). In addition, the gas tank attachment device 10 provides a low friction surface for inserting and removing the gas tank (T) to and from the gas tank attachment device. In addition, the gas tank attachment device 10 allows the gas tank (T) to be properly positioned relative to the gas tank attachment device 10 or the base member 12. This allows the user (U) to quickly replace the gas tank T in the operating environment. In addition, through the use of the above-mentioned contact 18 and the seat portion 14, an improved bottom load effect is provided. In addition, the "floating" contact 18 will effectively depress and provide contact with the seat portion 14, such as the seat contact 80. Maximum contact, thereby ensuring that the gas tank (T) will not move when clamped on the base part 12.
