Self-contained breathing apparatuses (“SCBAs”) commonly are used by firefighters and other first responders to protect such individuals from the smoke, airborne carcinogens, and other airborne hazards often present in the environments within which first responders operate.
SCBAs commonly are stored and transported in the crew area of emergency vehicles. Due to concerns regarding possible exposure to carcinogens from the SCBAs themselves, however, there is a trend in the first-responder community to remove SCBAs from crew compartments, and to transport the SCBAs in unoccupied areas of the emergency vehicles.
A typical SCBA, however, is bulky, and the storage compartments on many emergency vehicles are limited in size. Also, the storage compartments on large emergency vehicles such as fire engines often are located above ground level. For example, the floor of a storage compartment on a typical fire engine may be five feet above ground level, necessitating the use of a ladder or step stool to access and deploy equipment stored in the compartment.
Thus, due to the limited volume and the elevated location of the storage compartments of many emergency vehicles, it may be difficult for first responders and other users to quickly and easily access and deploy SCBAs stored in such compartments. And these difficulties can be exacerbated by the low visibility and foul weather conditions, and the exigent circumstances under which first responders often must operate.

A bracket system 10 is provided for the storage and retrieval of an article of equipment such as a self-contained breathing apparatus (SCBA) 11 of the type used by firefighters and other first responders to provide breathing air during firefighting and other emergency operations. The use of the system 10 is disclosed in connection with the SCBA 11 for illustrative purposes only. The system 10 can be used to store and retrieve other types of cylindrical, and non-cylindrical articles of equipment.
The bracket system 10 comprises two mounting brackets 12, and a tray 14 mounted on the mounting brackets 12. The mounting brackets 12 are configured to be secured to a mounting surface 104, using fasteners or other suitable means. The mounting surface 104 can be, for example, a floor of a storage compartment 102 of a fire engine 100 shown in
The use of the bracket system 10 in connection with the fire engine 100 is disclosed for illustrative purposes only. The bracket system 10 can be installed on other types of emergency vehicles, and on any type of vehicle having sufficient space inside or outside of the vehicle to accommodate the bracket system 10 and the article of equipment being stored thereon. The system 10 also can be used in non-vehicular applications, and can be installed, for example, in apparatus bays, closets, storage lockers, storage rooms, etc. If desired, multiple bracket systems 10 can be mounted next to each other in very close proximity, to facilitate the storage and retrieval of multiple SCBAs 11 and other equipment.
The bracket system 10 securely stores the SCBA 11 in a stowed position in which the SCBA 11 has an upside down, or inverted orientation, facing the back of the storage compartment 102, i.e., facing away from a user standing adjacent to the storage compartment 102. The bracket system 10 is configured to articulate in a manner that positions the SCBA 11 in a lowered position at which the SCBA 11 has an upright orientation, facing the user, so that the user can retrieve the SCBA 11 quickly and easily. Because the bracket system 10 lowers the SCBA 11 as the SCBA 11 is retrieved, the user can retrieve the SCBA 11 from an elevated storage compartment without the need for a ladder or a step stool. This can be seen, for example, in
The bracket system 10 allows the SCBA 11 to be stored in areas of the fire engine 100 apart from the crew area. In one possible application, the bracket system 10 can be used to store one SCBA 11 in a minimally-sized sized storage compartment on the fire engine 100. Since a typical height of such compartments may be about five feet from the ground level, the bracket system 10 allows SCBA 11 to be stored in such a compartment, and to be accessed and retrieved by a user at ground level without a ladder or step stool, and in a manner that permits the user to quickly and easily don the SCBA 11.
The tray 14 is configured to move in relation the mounting brackets 12, between a first, or stowed position shown in
Each bracket 20 can have a load capacity of, for example, about 45 pounds. The brackets 20 can have other load capacities in alternative embodiments.
The bracket system 10 also includes a locking lever 21. The locking lever 21 is mounted on one of the mounting brackets 12 by way of a pin that permits the locking lever 21 to rotate in relation to the mounting bracket 12, between a first angular position, or locking position shown, for example, in
The locking lever 21 does not interfere with the extension of the bracket 20 when the locking lever 21 is in the releasing position. When the user wishes to retrieve the SCBA 11 from the bracket system 10, the user presses downward on one end of the locking lever to rotate the locking lever 21 in a clockwise direction, from the perspective of
As can be seen in
In alternative embodiments, a gravity-actuated pin can be used in lieu of the locking lever 21. The pin can be configured to move vertically between a lower position at which the pin contacts the forward edge of one of the brackets 20 or the platform 14 to prevent the bracket 20 or the platform 14 from extending outward, and an upper position at which the pin does not interfere with the outward extension of the bracket 20 or the platform 14. Optionally, a spring can be used to bias the pin in the downward direction.
Referring to
As discussed below, the backplate 22 is coupled to the tray 14 so that the backplate 22 can rotate in relation to the tray 14 between a first angular position, or raised position shown in
Referring to
The strap 24 is equipped with a buckle that permits the user to quickly release the SCBA 11 from the backplate 22 so that the user can retrieve the SCBA 11 from the backplate 22 with minimal time and effort. In alternative embodiments, the bracket system 10 can include more than one strap 24. In other alternative embodiments, the strap 24 (or straps 24) can be a cam strap, to facilitate quicker and easier cinching of the strap around the SCBA 11.
The clips 26 are sized to receive the SCBA 11. The clips 26 can be formed from spring steel or another suitable material that resiliently deflects when the SCBA 11 is received by the clips 26, so that the clips 26 hold the SCBA 11 in place until the SCBA 11 is secured by the strap 24. Alternative embodiments of the backet system 10 can include more, or less than two clips 26. The clips 26 can be coated with a cycle tested, durable high-cycle coating to protect the cylinder of the SCBA 11 from wear or other damage caused by contact with the clips 26.
Referring to
As noted above, the backplate 22 is mounted on the tray 14, and is configured to rotate in relation to the tray 14 between a first angular position, or raised position shown in
Referring to
The cross member 34 is secured to the backplate support member 39 proximate a first end 41 of the backplate support member 39, as can be seen in
The backplate 22 and the backplate support member 39 are sized and otherwise configured to withstand the loads that occur within those components when the attached SCBA 11 is flipped and lowered during the retrieval process.
Referring to
The slots 48 and the locking plate 40 are configured so that the locking plate 40 rests in its locking position when the backplate 22 is in its raised position. The locking plate 40 remains in its locking position due to gravity. In alternative embodiments, the locking plate 40 can be biased toward is locking position by a spring, to further reduce the potential for accidental or otherwise unintended rotation of the backplate 22, the backplate support member 39, and the SCBA 11.
As can be seen in
The user can rotate the backplate 22 to its lowered position by lifting the locking plate 40 to its released position. As can be seen in
When the locking plate 40 is in the released position, the bottom edge of the locking plate 40 is higher than the top of the stop 36. Thus, the stop 36 no longer interferes with to rotation of the backplate 22, and the backplate 22 can be rotated to its lowered position. When the backplate 22 subsequently is returned to its raised position, the angled upper surface of the stop 36 urges the locking plate 40 upward so that the locking plate 40 can clear the stop 36, after which the locking plate 40 returns to its locking position due the gravity.
Alternative embodiments of the bracket system 109 can be equipped with one or more dampers that dampen or slow the rotation of the backplate 22 as the backplate 22, with the attached SCBA 11, translates to its lowered position. The dampers can be, for example, rotational dampers, with each damper coupled to a respective bracket 30 and its corresponding pin 35. Other types of dampers, mounted at other locations on the bracket system 10, can be used in other alternative embodiments.
In use, the SCBA 11 can be securely stored on the bracket system 10 within, for example, the storage compartment 102 of the fire engine 100. When in the stored condition, i.e., when in its stowed position, the SCBA 11 is upside down, or inverted, and faces toward the inside of the storage compartment 102. The backplate 22, with the attached SCBA 11, is secured in its raised position by the locking plate 40 and the stop 36; and the tray 14 is secured in its stowed position by the locking lever 21.
When a user wishes to retrieve the SCBA 11, the user moves the locking lever 21 to its released position, and then pulls the tray 14 outward, away from the storage compartment 102 and into its semi-deployed position. The user then lifts the locking plate 40 and pulls the backplate 22 outward and downward to rotate the backplate 22 from its raised position to its lowered position, as can be seen in
Thus, the user can quickly retrieve the SCBA 11 from its secure position within the elevated compartment 102. The user can perform the entire retrieval process from ground level, and can safely and easily release the interlocks that secure the tray 14 and the backplate 22 in their proper relative positions before and during the various phases of the retrieval process. The retrieval process can be performed easily under low visibility and adverse weather conditions, and without the need for any keys or tooling. The bracket system 10 thus facilitates stowage of the SCBA 11 outside of the crew compartment of the fire engine 100, while allowing quick and easy access to, and deployment of the SCBA 11 once the fire engine 100 (or other vehicle) arrives at its destination.
