HOSE CLAMPING DEVICE

Abstract: A universal hose clamp (1) is described, which comprises a universal hose locating mechanism (2), a hose coupling (4) for connecting a hose to the hose clamp (1), and a securing means for securing said locating mechanism to a support structure. The universal hose clamp (1) may be employed to secure a hose to an existing support structure (22) or to a portable independent frame (23). It is designed to be adaptable for use with a range of hose diameters and as such the universal hose clamp (1) can be employed in a wide range of emergency situations. When deployed the universal hose clamp (1) provides a means for rotating the hose coupling (4) in any direction and thereafter the hose coupling (4) can be locked in that position. Therefore, with the aid of the universal hose clamp (1) only one operator is required to control a hose device in an emergency situation.

Description: Hose Clamping Device The present invention relates to a device for securing hoses, particularly those used by fire fighters. When fighting a fire there are a number of problems to be addressed in addition to extinguishing the fire, for example rescuing those who are trapped or crowd control. As a result the available human resources need to be carefully targeted to limit/prevent the occurrence of injury. The present invention recognises that as part of fire- fighting the use and control of a hose is an onerous task requiring the efforts of several people. The present invention attempts to mitigate this problem and allow for better targeting of available resources. It is an object of the present invention to provide a device whereby a hose can be clamped to a support thus allowing fire fighters to be released from such duties and available for other tasks, for example rescuing those who are trapped. It is a further object that such a device will be simple to use and readily adapted to the dimensions of different hoses. According to the present invention there is provided a universal hose clamp comprising a universal hose locating mechanism, a hose coupling for connecting a hose to the hose clamp, and a securing means for securing said locating mechanism to a support structure.

More Preferably the attachment means is by way of an Azimuth locking mechanism. In order to provide a better understanding of the invention embodiments will now be described by way of example only with reference to the accompanying Figures in which: Figure 1 illustrates a universal hose clamp for locking and securing a hose; Figure 2 illustrates a component of the universal hose clamp, namely a universal hose locating mechanism, with two Azimuth locking mechanisms shown in a locked position; Figure 3 and 4 illustrate separate perspective views of a further component of the universal hose clamp, namely a universal base clamping mechanism shown clamped to a Y-shaped handrail; Figure 5 illustrates the universal hose clamp of Figure 1 one of the universal Azimuth locking mechanisms for controlling the hose clamp rotation about the vertical axis in the unlocked position; and Figure 6 illustrates a tripod on which the universal hose clamp of Figure 1 can be mounted; Referring initially to Figure 1, a universal hose clamp is generally depicted at 1 comprising a universal hose locating mechanism 2, a universal base clamping mechanism 3 and a hose coupling . The hose ccoupling 4 comprises a cylindrical gripping aid 5, a cylindrical mounting band 6 and a screw thread mechanism 7. Figure 2 illustrates further detail of the universal hose locating mechanism 2 in the absence of the base clamping mechanism 3 and the hose coupling 4. The hose locating mechanism 2 comprises a central mount 8, two Azimuth locking mechanisms 9 and 10 and a quick release hose mount 11. The two Azimuth locking mechanisms 9 and 10 further comprise a handle assembly 12, a connection means 13 and a stab pin 14 or 15. The connection means 13 provides the activation mechanism for moving the Azimuth locking mechanisms 9 and 10 between their unlocked and locked positions. In Figure 2 both locking mechanisms 9 and 10 are in their locked positions. When unlocked the first Azimuth locking mechanism 9 allows rotation of the hose mount 11, and hence the hose coupling 4, about a horizontal axis while the second Azimuth locking mechanism 10, when unlocked, allows rotation about a vertical axis. It should be noted at this point that these two mechanisms lock independently of each other such that one may be in the locked position while the other is in the unlocked position. The stab pins 14 and 15 provide male members for the Azimuth locking mechanisms 9 and 10, respectively. Figures 3 and 4 present further detail of the universal base clamping mechanism 3 in the absence of the hose locating mechanism 2. The base clamping mechanism 3 comprises a central frame 16, a rail clamp 17 and a female 18 for the Azimuth locking mechanism 10. The rail clamp 17 further comprises a swing over lock 19, a rail clamp tightening assembly 20, and two threaded locating rails 21. The combination of the hose locating mechanism 2 and the base clamping mechanism 3 is achieved by inserting the stab pin 15 in the female locking component 18 with the handle assembly 12 in the unlocked position, as in Figure 5. This unlocked position corresponds to the case when the handle assembly 12 is in a plane parallel to the stab pin 15. The locked position is achieved by rotating the handle assembly 12 through 90 degrees such that the handle assembly 12 now lies in the plane perpendicular to the stab pin 15, as in Figure 1. To employ the universal hose clamp 1, the base clamping mechanism 3 is attached to a railing, pole or other similarly reinforced structure. As shown in Figure 1, the desired structure to which the hose clamp 1 can be attached may take the form of a Y-shaped rail 22. Initially the swing over lock 19 is opened by unscrewing one of the threaded locating rails 21. This allows the rail clamp 17 to be placed in situ around the hand rail 22. With the hand rail 22 in place above the threaded locating rails 21, the swing over lock 19 is then closed and fastened. The base clamping mechanism 3 is then secured in place by tightening of the rail clamp 17 by use of the rail clamp tightening assembly 20. The second stage is to attach the hose locating mechanism 2 to the base clamping mechanism 3 via the vertical Azimuth locking mechanism 10 as described above. Thereafter the hose (not shown) is inserted within the cylindrical hose gripping aid 5 which is then tightened in the cylindrical mounting band 6 that is attached to the quick release hose mount 11. The tightening of the cylindrical hose gripping aid 5 in the cylindrical mounting band 6 is achieved via the screw thread mechanism 7. With the horizontal Azimuth locking mechanism 9 in the unlocked position the hose coupling 4 is mounted on the horizontal stab pin 14. At this stage the hose is secured within the hose clamp 1 and can be deployed at full pressure by just one person. This has the obvious advantage of releasing manpower to carry out other important duties. By simply unlocking either of Azimuth locking mechanisms, 9 and 10, the hose can be rotated to provide universal cover over 4π steradians. Mobility for the hose coupling 4 may be enhanced by its incorporation with a tripod system 23, as illustrated in Figure 6. This tripod 23 comprises a female member 24 for use in an Azimuth locking mechanism 10, adjustable legs 25 and a cross brace 26 to provide additional strength. It should be noted that the aforementioned female 24 is of a similar design to the female member 18 used in the previously described embodiment. Therefore, there is no requirement for the modification of the hose locating mechanism 2. With this embodiment the tripod is assembled at the required location. The hose (not shown) is then mounted in the hose locating mechanism 2 as previously described. The vertical stab pin 15 is then inserted in the female of the tripod 18 and locked as required by the vertical Azimuth locking mechanism 10. The use of alternative hose diameters is determined by the nature of the emergency. Thus the hose coupling 4 is not limited to use with one particular hose size. Selection of a hose can be accommodated within a particular cylindrical gripping aid 5 by the adjustment of the screw thread mechanism 7. If the hose diameter is significantly different then the quick release hose mount 11 allows a second hose clamp 4 of the desired dimensions to be quickly mounted on the hose locating mechanism 2. An advantage of the present invention is that there is provided a universal hose clamp which can be used with known types of hose and whose parts are readily interchanged to meet the requirements of different emergency situations. A further advantage of the present invention is that there is provided means which will reduce the manpower required to control a hose, and increase the numbers available to help those who are part of the emergency situation. A further advantage of the invention is that the individual securing means are able to rotate such that the hose can be used in any direction thus allowing the changing needs of an emergency situation to be met. In an alternative embodiment the clamp may be provided with means to enable control from a remote source. For example an electronic receiver and control electronics could be mounted within the central mount 8 of the universal hose locating mechanism 2. This would allow the direction of the hose coupling 4 to be altered without the requirement for direct human contact. Further modifications and improvements may be added without departing from the scope of the invention herein intended.
