The present invention deals with brackets and other similarly constructed mounting devices utilized for detachably securing of cylindrical tanks such as emergency breathing apparatus tanks in position within emergency vehicles. It is important that such tank be fully and securely held therein but also be available for quick and easier removal by emergency personnel once the vehicle reaches the location of the fire or other emergency. Many devices have been designed for detachably securing such tanks including various clamping mechanisms and most are utilized for storing the cylindrical tank in an inverted position since this is the tank position when attached to the torso of an emergency worker. The present invention provides a unique means for minimizing extremely rapid or instantaneous movement of the bracket from the clamping position to the releasing position which would be experienced in an accident by the emergency vehicle or an unusually rapid movement. Such cylindrical tanks are quite heavy and the uncontrolled release of such a heavy piece of equipment during an accident or other rapidly decelerating incident could easily injure emergency personnel in the immediate area.
Many prior art devices have been utilized for the purpose of retaining cylindrical tanks in an inverted position which are designed to hold them securely while allowing rapid release when needed.

The accompanying drawings, which are incorporated herein and constitute part of this specification, illustrate the presently preferred embodiments of the invention, and, together with the general description given above and the detailed description given below, serve to explain the features of the invention. In the drawings:
In the drawings, like numerals indicate like elements throughout. Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. The following describes preferred embodiments of the present invention. However, it should be understood, based on this disclosure, that the invention is not limited by the preferred embodiments described herein.
Referring to
The mounting assembly 20 includes a backing plate 11 which is generally a vertically extending member and which can be easily attached to a seatback or any other environmental structure within an emergency or other vehicle for the purpose of facilitating mounting of the cylindrical tank 10 therewithin. The backing plate 11 often define a plurality of apertures extending therethrough to facilitate securement with threaded fasteners such as screws or bolts with respect to environmental structure.
A foot member or foot plate 14 is secured to the bottom portion of the backing plate 11 and is adapted to support the tank head 9 of cylindrical tank 10 in an inverted position. Foot plate 14 is, preferably, defined in the shape of a foot cup 16 facing upwardly to facilitate receiving of the cylindrical tank head 9 therewithin. Guiding of movement of the cylindrical tank head 9 into the foot cup 16 is achieved by the positioning of a foot guiding plate 18 at an intermediate location within the foot cup 16 and spatially disposed from the backing plate 11. The foot cup 16 preferably includes a foot front stop 17 which is spaced from the foot guiding plate 18 by a distance approximately equal to the size of the cylindrical tank head 9. In this manner, as the tank 10 is moved into the tank receiving zone 16, the cylindrical tank head 9 comes into abutment with the foot guiding plate 18. As the tank 10 moves into the tank receiving zone 16, the foot guiding plate 18 guides the tank head 9 into the location between the foot guiding plate 18 and the front foot stop 17 of foot cup 16 due to the inclined orientation of the outer facing surface of the foot guiding plate 18. This apparatus significantly facilitates the repeated placement of a cylindrical tank head 9 in abutment with the present mounting assembly 20 when securing a cylindrical tank 10 oriented in an inverted position within the tank receiving zone 16.
A clamping assembly 22 extends from the backing plate 11 at a position significantly higher or above the location of the foot plate 14. In this manner, a tank receiving zone 16 extends longitudinally vertically along the vertically extending backing plate 11 between the clamping assembly 22 and the foot plate 14 therebelow. This tank receiving zone 16 as so defined facilitates the mounting of the cylindrical tank 10 in an inverted orientation with the cylinder tank head 9 positioned in abutment with the foot plate 14 and with the body portion 8 of the tank 10 extending upwardly along the backing plate 11, and generally parallel with respect thereto, to a location wherein positioning of a clamping member 30 of the clamping assembly 22 in a clamping position facilitates maintaining of the tank 10 in the inverted orientation. As described in more detail hereinafter, the clamping member 30 is movable between the clamping position illustrated in
The clamping assembly 22, preferably, is mounted with respect to the backing plate 11 in an orientation extending general perpendicularly outwardly therefrom. The clamping assembly 22 includes a bracket 21 having a back plate 23 with opposed side plates 25 extending therefrom. Preferably, the back plate 23 extends generally parallel with respect to the plane of the backing plate 11 at a location thereabove and the side plates 25 extend outwardly from the back plate 23. With this configuration, the bracket 21 has a generally C-shaped configuration which receives the body portion 8 of cylindrical tank 10 therein.
The clamping member 30 also has a generally C-shaped configuration with an arcuate central portion 32 extending between opposed arms 34 and 36. Each arm 34, 36 is pivotally attached to a respective side plate 25 via a pivot pin 27. The clamping member 30 is pivotally movable between the clamping position and the releasing position. In the clamping position, the cylindrical tank 10, including the tank head 9 and the tank body 8, are fixedly secured within the tank receiving zone 16. Movement of the clamping member 30 toward the releasing position releases the body 8 and head 9 of the cylindrical tank 10 from the tank receiving zone 16 and allows it to be released from the bracket assembly and utilized normally at the location of an emergency situation where emergency personnel would often need a portable supply of oxygen.
A return biasing means 28, illustrated as a flexibly resilient wire coil spring, is wound about one of the pivot pins 27 and is secured at both ends relative to the bracket 21. The wire coil spring engages the pivot pin 27 and biases the pivot pin 27, and thereby the clamping member 30, toward the clamping position with a moderate continuously exerted force. While a wire coil spring engaged with the pivot pin 27 is illustrated, other biasing assemblies may be utilized, for example, a coil spring extending between the bracket 31 and the clamping member 30. A stop 26 is positioned extending through one of the side plates 35 and engages the respective arm 34 and prevents over rotation of the clamping member 30.
Movement of the clamping member 30 from the clamping position to the releasing position to facilitate release of the tank 10 from the mounting assembly 20 is most commonly achieved by manually overpowering the force exerted by the return biasing means 28 by lifting the front portion of the clamping member 30 and causing it to pivot toward the releasing position. Preferably, the clamping member 30 is also configured to allow for automatic movement of clamping member 30 to the releasing position when the wearer of the tank 10 gets up from the seat they are in. To facilitate such, the clamping member 30 has an internal slope 39 (see
While it is convenient for the mounting assembly 20 to easily release the tank 10 when the wearer intentionally exits the seat, the mounting assembly 20 is configured such that the tank 10 will not be released do to an unintended lateral force, for example, an inertia force caused by a sudden, sharp change of speed of the vehicle. To achieve such, the mounting assembly 20 of the present embodiment includes an inertia dampening mechanism 40 which engages a portion of the clamping mechanism 30 and prevents pivoting thereof in response to a sudden high force.
The exemplary inertia dampening mechanism 40 includes a hydraulic control cylinder 42 which is attached to the bracket 21 via a dampener mounting bracket 41. In the illustrated embodiment, the dampener mounting bracket 41 has an L-shape and is attached to one of the side plates 25. The dampener mounting bracket 41 may have other configurations and may be otherwise attached, for example, to the back plate 23. Mounting is such that the control cylinder 42 is aligned with a contact plate 38 on the arm 34 of the clamping member 30. A piston rod 44 extends from the control cylinder 42 and terminates in a stop member 46 configured to contact the contact plate 38. The stop member 46 may be of any material such as rubber, plastic or metal. Alternatively, the stop member may be eliminated and the piston rod 42 may directly contact the contact plate 38.
The opposite end of the piston rod 44 includes a piston (not shown) positioned within the control cylinder 42. The piston is movable through a hydraulic media which may be fluid or gaseous. The piston and hydraulic media are selected such that flow within the control cylinder 42 restricts rapid movement of the piston rod 42 downwardly within the control cylinder 42. For example, the piston may have a small through hole which allows the hydraulic media to pass through, however, not at a rapid pace. As such, it is extremely difficult to rapidly collapse the piston rod 44 into the control cylinder 42. On the other hand, it is very easy to slowly move the piston rod 44 into the control cylinder 42 for slowly collapsing the piston rod 44 into the control cylinder 42.
As such, by mounting of the inertia dampening mechanism 40 in a position aligned with the contact plate 38, the inertia dampening mechanism 40 controls pivotal movement of the clamping member 30. More specifically, when the clamping member 30 is in the clamping position, the contact plate 38 is in generally direct abutment with the stop member 46 of the extended piston rod 44 as shown in
With the illustrated configuration, compression of the piston rod 44 into the control cylinder 42 of the inertia dampening mechanism 40 is required every time the clamping member 30 is pivoted from the clamping position to the releasing position. Thus, releasing of the cylindrical tank 10 from the tank receiving zone 16 can only be achieved after compression of the piston rod 44 into the control cylinder 42 of dampening mechanism 40. Thus, the operating characteristics within the inertia dampening mechanism 40 are such that it is highly resistant to high speed or sudden or instantaneous movement of the clamping member 30 toward the releasing position such as may be experienced in a vehicular accident or any exposure thereof to high laterally directed forces (high pivoting force) wherein release of the tank 10 from the bracket assembly 20 could provide a danger to any emergency personnel within the vehicle. However, with this construction, the movement of the clamping member 30 slowly from the clamping position to the releasing position, such as by manual operation thereof or automatic operation with movement from the seat (normal pivoting force), is easily achievable. Thus, the use of this construction of the present invention provides a means for allowing normal manual release of a tank 10 from the bracket assembly 20 of the present invention responsive to normal manual manipulation and operation or pivoting of the top clamping member 30 whereas, on the other hand, rapid movement responsive to extremely high or instantaneous laterally direct forces are rendered virtually impossible. This construction provides an important safety advantage to prevent the somewhat heavy and cylindrical tank 10 from being released in response to a vehicular accident because the release of such a tank under those circumstances could easily injure surrounding emergency personnel seated within the passenger compartment of the emergency vehicle.
Referring to
The inertial locking bar assembly 50 includes a locking bar 52 which is pivotally connected at one end to the other bracket side plate 35 at pivot point 53. The opposite end of the locking bar 52 includes a weight 56. The weight 56 may be secured to the locking bar 52 as illustrated or may be formed integrally therewith. The locking bar 52 defines a sloped shoulder 55 which contacts the contact plate 37 on arm 36 of the clamping mechanism 30 and maintains the clamping mechanism 30 in the clamping position. The clamping mechanism 30 is prevented from rotating to the releasing position so long as the locking bar 52 is in a locking position with the shoulder 55 aligned with the contact plate 37, as illustrated in
To maintain the locking bar 52 in the locking position, a dampening member 60 is secured to the locking bar 52 via a bracket 59. The dampening member 60 is similar to the inertia dampening mechanism 40 and includes a control cylinder 62, a piston rod 64 with a stop member 66 on one end and a piston (not shown) on the other end within the control cylinder. A hydraulic media within the control cylinder controls movement of the cylinder in a manner similar to that described above. The dampening member 60 is positioned such that in the locking position, the piston rod 44 is extended from the control cylinder 62 and the stop member 66 is engaged with the back plate 23 of the bracket 21.
To move the clamping member 30 to the releasing position as illustrated in
The clamping assembly 22′ of the present embodiment includes both the inertia dampening mechanism 40 and the inertia locking arm assembly 50 which provides redundancy. If such redundancy is not required in a particular application, it is understood that the clamping assembly 22′ may include only the inertia locking arm assembly 50.
These and other advantages of the present invention be apparent to those skilled in the art from the foregoing specification. Accordingly, it be recognized by those skilled in the art that changes or modifications may be made to the above-described embodiments without departing from the broad inventive concepts of the invention. It should therefore be understood that this invention is not limited to the particular embodiments described herein, but is intended to include all changes and modifications that are within the scope and spirit of the invention as defined in the claims.
