The invention relates generally to an adjustable mounting system, and, more specifically, to an adjustable mounting system for a nozzle.
The most common firefighting nozzle has a 1.5″ diameter nozzle in accordance with National Fire Protection Association (NFPA) Specifications. There are a number of manufacturers of 1.5″ diameter nozzles. However, there are variances between nozzles from different manufacturers and thus there currently exists many different types of these nozzles. For example, some nozzles are very simple while some are very complex, and some are light in weight while others are quite heavy.
Fire trucks generally carry a number of different types of 1.5″ nozzles. For example, some nozzles are pre-connected to a 1.5″ hose that is pre-connected to the appropriate discharge. However, mounting pre-connected nozzles presents a significant challenge. A pre-connected nozzle ensures that a 1.5″ hose is usually the first hose on the fire. The 1.5″ pre-connect hose is usually a “cross lay hose bed” on top of the fire truck. In some cases, the 1.5″ nozzle is carried in the hose bed. This could be located seven feet or more off the ground, thereby requiring a fire fighter to climb on the running board of the fire truck to reach the line. This can be dangerous, e.g., in bad weather conditions, resulting in falls.
Due to the popularity of 1.5″ pre-connects, there are often multiple pre-connects. In order to minimize confusion, the control valves may have various color combinations on the pump panel with colored stripes on the fire hose that match the color for that hose on the pump control. The NFPA has described how these colors help to easily identify each pre-connect. However, it is often difficult and expensive to buy custom colored fire hose.
Some nozzles are not pre-connected, but are stored in an equipment compartment on tool boards or shelves, for example, while screwed into a screw plate which is a threaded male fitted base. The storage compartment is often congested and it may be difficult to mount nozzles either horizontally or vertically. There are also mounts that are “Tri Lock” spring action mounts in which three sets of teeth lock into the swivel female threads (internal threads) of the nozzle. Often, these sharp teeth can cause serious damage to the female threads causing significant and expensive damage. Mounting on a screw plate makes it difficult to turn the swivel by hand onto the screw plate, especially because it must be tightly screwed for it to be stable. Further, there commonly exists violent shaking of a truck on a rough road so stability is important.
A possible solution to this problem is disclosed in U.S. Pat. No. 8,020,895 (Reichmuth). Reichmuth discloses a pipe clamp and mounting structure that mounts a pipe to a fastening body. The device uses a holder which secures to the fastening body and a clamp that interlocks within the holder. The pipe that is mounted by the device has ribs corresponding to grooves cut into the holder which secure the pipe to the holder. The pipe can also be secured to the fastening body by resting in the holder and having the clamp lock around the pipe, fitting into a channel positioned between two ribs on the pipe. However, Reichmuth fails to disclose a mounting structure that can not only mount pipes, but be manipulated to secure other equipment such as boxes or cylindrical vessels. Additionally, Reichmuth fails to disclose a corresponding flexible mount module to further support the pipe that can be adjusted to accommodate a pipe with a larger or smaller diameter when compared to the size of the pipe secured within the mounting structure. Moreover, Reichmuth fails to disclose a strap that can be adjusted to have a greater tension if external forces act on the pipe and possibly cause the pipe to become unsecured.
Another possible solution to this problem is disclosed in U.S. Pat. No. 7,581,292 (Votel). Votel discloses a clip comprising opposed arms in mechanical communication with jaw members biased in a contacting relation. The jaw members are forced apart by a user applying opposing forces to each of the arms. The jaw members operably grasp the article when the arms are released. The clip has a structure for detachably interlocking with another clip. The clip may be made from a resilient material and includes a base structure defining an aperture and a gap, which enable the detachable interlinking However, Votel fails to disclose a method for adjusting the distance between the two jaw members to accommodate larger objects which require securing. Additionally, Votel fails to disclose an adjustable locking assembly further comprising an adjustable strap to ensure an object is secured along its length.
Even further, another possible solution to this problem is disclosed in U.S. Pat. No. 4,960,063 (Bontemps). Bontemps discloses a safety device for the foot-holder of a sailboard or the like in which the foot-holder has a strap fixed at one end on the sailboard and another end secured to a latch which can be engaged in a locking body. The latch and locking body are arranged so that under a force exerted on the latch in a certain direction, the latch is unlocked to enlarge the loop while remaining engaged in the locking body. Under a stress exerted on the latch in a second direction, the latch is released from the locking body and opens the loop. However, Bontemps fails to disclose a means of adjusting the distance between the fixed end and the latch end of the strap. Instead, both ends of the strap are secured and only the length of the strap can be adjusted. Additionally, Bontemps fail to disclose a corresponding flexible mount module to further support the object that is locked within the strap. Moreover, Bontemps fails to disclose a locking module which would secure a universal nozzle connector.
Therefore, there is a long-felt need for an apparatus for storing non pre-connected nozzles to increase the speed of mounting and dismounting, while also increasing the storage stability. Further, there is also a long-felt need for a mounting system that will accommodate a pre-connected nozzle at a height level easily reached by a user while standing on the ground and that is arranged to accommodate a variety of nozzle sizes.

These and other objects, advantages and features of the present invention will be better appreciated by those having ordinary skill in the art in view of the following detailed description of the invention in view of the drawings.
The nature and mode of operation of the present invention will now be more fully described in the following detailed description of the invention in view of the accompanying figures, in which:
At the outset, it should be appreciated that like drawing numbers on different drawing views identify identical, or functionally similar, structural elements of the invention. While the present invention is described with respect to what is presently considered to be the preferred aspects, it is to be understood that the invention as claimed is not limited to the disclosed aspect. The present invention is intended to include various modifications and equivalent arrangements within the spirit and scope of the appended claims.
Furthermore, it is understood that this invention is not limited to the particular methodology, materials and modifications described and as such may, of course, vary. It is also understood that the terminology used herein is for the purpose of describing particular aspects only, and is not intended to limit the scope of the present invention, which is limited only by the appended claims.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices or materials similar or equivalent to those described herein can be used in the practice or testing of the invention, the preferred methods, devices, and materials are now described.
Because of the emergency nature of firefighting, the time required to get a hose “on the fire” is of major importance. Consequently, the speed of releasing a pre-connect from a mounting system is of considerable importance. A grab-and-go system, with the fire fighters' feet on the ground, is most desirable. Any pre-connect nozzle mounting system has to accommodate environmental conditions. Therefore, the present mounting system is resistant to weather extremes, e.g., from subzero temperatures to extreme heat and UV exposure. Moreover, the present system is easily adjustable because the length, size and weight of 1.5″ diameter nozzles can vary greatly.
Frequently, 200 feet of 1.5″ diameter hose is pre-connected between a pump discharge and a 1½ inch nozzle. To store the hose, the pump discharge valve must be closed, the 1½ inch nozzle valve control opened and any water in the hose drained out. The hose is then folded into the hose bed. In many cases, the nozzle is stored with the nozzle control valve in the open position. The handler valves connected to the nozzle are often quite large. Any mounting of these nozzles must recognize space required not only for the nozzle itself, but also for the handle. Some also include a pistol grip that can often be large. The present system accommodates the foregoing constraints.
Further, the pre-connected nozzle may be required to mount vertically attached to the side of the truck or it may be mounted horizontally on the front bumper or other area. Even further, the length, weight and discharge end of the nozzle can vary greatly so it is necessary that there be a cradle mount for the discharge end that can easily be adjusted to provide a secure customized mount for the nozzle. The result is a locking mount for the base swivel end of the nozzle and a friction clamp type mount for the discharge end. A track system is used to easily adjust the length between the two mounts.
Mounting any equipment on a mobile vehicle must recognize the various gravitational forces generated when the truck runs over bumps or holes in the road. To counter-act these forces, the present invention supports both the inlet end and the discharge end of the nozzle. The support on the discharge end is easily adjusted to not only a wide range of diameters but also to variances in the distance between the inlet end and discharge end of the nozzles. The current invention allows for easy movement and be securely locked into position once a dimension is finalized.
Referring now to the Figures,
The 1.5″ diameter swivel on every nozzle is substantially similar; therefore the present mounting system is related to this connection. A 1.5″ diameter internal threading 22 and a 1.5″ diameter external threading 24 of connector 20 are installed between and join the discharge end of the 1.5″ diameter hose and the 1.5″ diameter swivel inlet of a nozzle thereby providing a common dimensional structure for mounting all nozzles. Universal connector 20 may be anodized with NFPA recognized colors thereby serving to identify the 1.5″ diameter discharge valve at a pump panel with a particular pre-connected line.
Further, universal connector 20 enables the nozzle to be mounted on a firefighter's hip with a hip holster. A hip mounted holster provides efficient movement in and out in order to relieve strain on a fire fighter's arms while pulling or using the discharge from the nozzle on the fire. Nozzle reaction forces on a 1.5″ diameter nozzle discharging 150 GMP at 100 PSI are intense, often requiring two men to handle the hose and nozzle. By transferring reaction forces from arms to the hip greatly reduces fatigue. Likewise, dragging a 1.5″ diameter line filled with water is extremely tiresome for the firefighter.
Thus, it is seen that the objects of the present invention are efficiently obtained, although modifications and changes to the invention should be readily apparent to those having ordinary skill in the art, which modifications are intended to be within the spirit and scope of the invention as claimed. It also is understood that the foregoing description is illustrative of the present invention and should not be considered as limiting. Therefore, other embodiments of the present invention are possible without departing from the spirit and scope of the present invention as claimed.
