    Description


    [0001] This invention relates generally to deployment apparatus for coiled or rolled resources and more particularly, but not necessarily exclusively, to deployment apparatus for laying and recovery of road covering track normally stored in a rolled configuration such as, for example, a traversable temporary roadway, walkway or runway.

    [0002] It is known, in many applications, to transport and deploy a temporary roadway system, wherein a road-covering track comprising interconnected profiled panels, is wound around a spool into a roll. In a known deployment method, the spool may be mounted, via a spool stand, on a flatbed body or trailer of a heavy goods vehicle, such that the winding axis of the spool is perpendicular to the longitudinal axis of the vehicle body. As illustrated in Figure 1 of the drawings, the road-covering track 1 is drawn off the spool 2 and a pair of chains and straps 5, which are attached at the end of the track1, are positioned under the vehicle's rear wheels 4, over a pair of rollers 4a, as shown in Figure 1A of the drawings. The vehicle 3 then reverses, placing the chains/straps 5 under tension and causing the road-covering track 2 to be removed from the rotating spool 2 and laid onto the ground.

    [0003] Other methods for deployment of this type of road-covering track are also known, that employ vehicles such as a tele-handler or wheeled loader, but they all operate in much the same manner as described above, whereby a constant tensioning device is used to automatically lay the roadway in tension and the laying process is determined by the speed of the moving vehicle. An alternative method of deployment may be performed by means of a remote control device that requires the operator and driver to synchronise the speed of vehicle travel with the speed of spool rotation. The operator depresses the spool rotation button on the pendant control to correspond with the travelling speed of the vehicle. If the electrical system fails, the operator can use hydraulic manual override levers to rotate the spool and, if complete hydraulic failure occurs, the operator can operate a manual handpump to release the spool rotation and the roadway can be manually pulled from the spool and placed under the vehicle's wheels.

    [0004] In all of these cases, it normally requires at least two people to set up the deployment apparatus for use, namely the driver and an operator, and the process can be time consuming and awkward. There are many commercial and military applications in which a temporary road covering track of this type is required to be deployed and subsequently recovered, quickly and conveniently, especially within rough terrain and/or potentially hazardous environments, where speed and efficiency are paramount, without necessarily requiring two or more operatives to effect such deployment.

    [0005] DE3330098 A1 discloses a device for better laying of rollable floor coverings from a vehicle using a loading surface, which can be pivoted out of the longitudinal direction of the vehicle by approximately 90°, with, arranged on opposite sides, two bearing blocks for receiving the spool shaft. The device brings about the laying of rollable floor coverings with constant tensile stress in the laying direction. As a result, not only are too loose laying and possible fold formation in the laid floor covering avoided, but the loadability of the laid floor coverings is also increased.

    [0006] DE8323928 U1 discloses a device for laying rollable flooring from a vehicle using a loading surface pivotable about 90 ° from the longitudinal direction of the vehicle with two sides opposite to one another.

    [0007] It is an object of aspects of the present invention to address at least some of these issues and, in accordance with a first aspect of the present invention, there is provided a deployment apparatus for laying a traversable road covering track, the apparatus comprising a base having a spool stand mounted for rotation about it's vertical axis between a transportation configuration, wherein the longitudinal axis of the spool stand is substantially parallel to the longitudinal axis of the base, and a deployment configuration in which the longitudinal axis of the spool stand is substantially orthogonal to the longitudinal axis of the base, the spool stand having a spool mounted thereon for rotation about an axis parallel to the longitudinal axis of the spool stand, wherein a length of road covering track may be provided on said spool in a roll having a leading outer end at a first longitudinal side of said spool, characterised in that the apparatus further comprises at least one substantially rigid arm that extends upwardly from said spool stand, at a second, opposing longitudinal side of said spool, said rigid arm comprising upper, intermediate, and lower integral arm section, said rigid arm being rigidly coupled to an upper end of a support strut of the spool stand ; and wherein the upper are section extends substantially vertically upward, relative to said second longitudinal side of said spool stand, to a point at least halfway up the roll of track, the upper
    arm being positioned in use to ensure that a resultant space between an inner wall of the rigid arm an the spool is sufficient to accommodate the fully rolled track. In a first exemplary embodiment, a single arm may be provided at a location substantially half way along the length of said second longitudinal side of said spool. In an alternative exemplary embodiment, at least two arms may be provided at locations substantially adjacent to opposing ends of said longitudinal side of said spool. However, it will be appreciated by a person skilled in the art that any number of deployment arms may be provided, and the present invention is not necessarily intended to be limited in this regard. It is also to be understood that the term 'arm' used herein is not intended to limit the configuration of this element of the apparatus - the 'arm' could, for example, be wider than it is long and still perform the same function.

    [0008] More generally, in an exemplary embodiment, an inner profile of said arm may generally define a curve having a radius substantially matching, or greater than, the radius of said roll so as to accommodate the roll in a space defined between said inner profile and said spool. Thus, in theory, the arm could be formed in a single, curved section to accommodate this profile.

    [0009] Optionally, the upper end of said arm may terminate at a height substantially half way, or more, up the roll, in use. The or each arm may comprise at least three connected or integral arm sections. In this case, the arm sections may, once again, comprise respective elongate bars coupled, joined or formed integrally at adjoining ends, said arm sections being angularly oriented relative to each other.

    [0010] In accordance with another aspect of the present invention, there is provided a heavy wheeled or tracked vehicle having mounted thereon a deployment apparatus substantially as described above.

    [0011] These and other aspects of the invention will be apparent from the following specific description, in which embodiments of the present invention are described, by way of examples only, and with reference to the accompanying drawings, in which:

    Figure 6 is an image illustrating the apparatus of Figures 5A-5D in the first stages of deployment of the surface-covering track;



    [0012] Referring to Figure 2 of the drawings, a mobility and deployment system 10 for a heaving tracked or wheeled vehicle 12 comprises a frame 14 mounted on the bed of the vehicle 12. On the frame 14, a spool stand is mounted for rotation about its vertical axis between the transportation configuration illustrated in Figure 2, wherein the longitudinal axis of the spool stand is substantially parallel to the longitudinal axis of the vehicle 12, and the deployment configuration illustrated in Figure 3 of the drawings, in which the longitudinal axis of the spool stand 16 is substantially orthogonal to the longitudinal axis of the vehicle 12.

    [0013] A spool 18 is mounted on the spool stand for rotation about an axis parallel to the above-mentioned longitudinal axis of the spool stand 16. The spool 18 is supported at each end of the spool stand 16 and rotates on bearing surfaces. A length of road covering track 20 is mounted in a rolled configuration on the spool 18.

    [0014] As shown in Figure 2 of the drawings, in a first exemplary embodiment of the present invention, a single deployment arm 22 is provided, which is coupled to the spool stand 16, and supported by an elongate, generally upright strut 24. The strut 24 extends substantially vertically from the side edge of the spool stand 16, at a location substantially half way along the longitudinal edge thereof that is nearest the front of the vehicle 12 when the spool stand 16 is in the above-mentioned deployment configuration (such that it cannot be seen behind the spool 18 and roll 20 from the rear of the vehicle in Figure 3, when the spool stand is in the deployment configuration)..

    [0015] As can be best seen in Figures 2A, 2B, 2C and 2D of the drawings, the deployment arm 22 is rigidly coupled at, or formed integrally with, the upper end of the strut 24, and comprises three integral elongate arm sections, namely a lower arm section 22a, an intermediate arm section 22b and an upper arm section 22c. The lower arm section 22a extends upwardly and outwardly at an angle from a location adjacent an inner side edge of the above-mentioned longitudinal edge of the spool stand 16 and meets the upper end of the strut 24 at a location on its outer edge, close to the top of the lower arm section 22a. The intermediate arm section 22b extends from the top of the lower arm section 22a at an angle (relative to a nominal vertical axis) that is less than that at which the lower arm section 22a extends outwardly. The upper arm section 22c extends upward substantially vertically (or even slightly angularly toward the roll of track 20) from the upper end of the intermediate arm section 22b. As a result of the above-mentioned configuration, the inner wall of the deployment arm 22 effectively follows a 'curve' from the point at which the lower arm section 22a meets the spool stand 16, outwardly and upwardly to the upper end of the upper arm section 22c, the radius of the 'curve' generally matching that of the fully rolled track 20. In general, the deployment arm 22 needs only to be shaped and configured (in respect of its inner wall, i.e. the wall thereof that is immediately adjacent the rolled track 20) such that it extends outwardly (i.e. toward the front of the vehicle 12 when the spool stand 16 is in the deployment configuration) from where it is joined or coupled to the spool stand 16 (or frame 14), to ensure that the resultant space between the inner wall of the deployment arm 22 and the spool 18 is sufficient to accommodate the fully rolled track 20, and upwardly to terminate at a height around half way (or more) up the roll (as can be seen from Figure 3 of the drawings). In theory, the deployment arm could be a single arm section either curved into the required profile to accommodate the roll, or it could extend substantially vertically upward along its entire length, provided its lower end is coupled to the frame/spool stand at a location that is sufficiently far back from the outer surface of the roll.

    [0016] The upper arm section 22c is generally vertical relative to (or even angled slightly toward) the roll, with its inner wall adjacent to (i.e. very close to or even just touching) the outer surface of the track 20 in the fully rolled configuration, but without exerting any significant force or pressure thereon when it is at rest.

    [0017] Referring to Figure 4 of the drawings, in use, when the spool 18 is rotated (either by an operative pulling the free end of the track 20 (manually) or by means of a motor or the like, the free end of the track is released from the roll and fed out (toward the rear of the vehicle 12). Without any tension being applied to the end of the track, the net effect of this rotation is that the roll starts to unravel at the rear (i.e. the side nearest the front of the vehicle 12). However, in this case, any such unravelling is counteracted by the upper arm section 22c of the deployment arm 22, which, when the track 20 starts to unravel toward it, has the effect of exerting a radial force thereon (toward the spool 18), thereby pushing the leading edge of the track 20 in the opposite direction, toward the rear of the vehicle 12, and ensuring that the end of the track 20 is correctly fed from the spool 18.

    [0018] Once the end of the track 20 clears the rear edge of the frame 14 and the rear end of the vehicle 12, gravity acts on it to pull it downwardly toward the ground, thereby applying tension thereto. When the end of the track 20 has dropped to the ground, the vehicle 12 can reverse onto it, and as the vehicle continues to reverse, the remaining length of track 20 is pulled from the spool 18 and laid on the ground beneath the vehicle wheels.

    [0019] Referring to Figures 5A, 5B, 5C and 5D of the drawings, a deployment apparatus according to a second exemplary embodiment is illustrated, in which a pair of deployment arms 32 is provided, the deployment arms 32 being substantially identical and located close to opposing ends of the spool stand 16, spaced apart from one another along the rear longitudinal edge thereof (i.e. the edge nearest the rear of the vehicle when the spool stand 16 is in the above-mentioned deployment configuration).

    [0020] Once again, and in respect of each deployment arm 32, an upright strut 34 extends vertically upwardly from the outer edge of the spool stand 16 (or frame 14), but in this case, each deployment arm 32 comprises two integral arm sections, namely a lower arm section 32a and an upper arm section 32b. The lower arm section 32a extends upwardly and outwardly at an angle from a location adjacent an inner side edge of the above-mentioned longitudinal edge of the spool stand 16 and meets the upper end of the strut 34 at a location on its outer edge, close to the top of the lower arm section 32a. The upper arm section 32b extends substantially vertically upwardly to a point around halfway (or more) up the roll of track 20. In other exemplary embodiments, the upper arm section 32b may, once again, alternatively be angled slightly toward the roll of track 20.

    [0021] As before, in use and referring to Figure 6 of the drawings, when the spool 18 is rotated (either by an operative pulling the free end of the track 20 (manually) or by means of a motor or the like, the free end of the track is released from the roll and fed out (toward the rear of the vehicle 12). Without any tension being applied to the end of the track, the net effect of this rotation is that the roll starts to unravel at the rear (i.e. the side nearest the front of the vehicle 12). However, in this case, any such unravelling is counteracted by the upper arm sections 32b of the deployment arms 32, which, when the track 20 starts to unravel toward it, have the effect of exerting a radial force thereon (toward the spool 18), thereby pushing the leading edge of the track 20 in the opposite direction, toward the rear of the vehicle 12, and ensuring that the end of the track 20 is correctly fed from the spool 18.

    [0022] In the case of both the first and second exemplary embodiments described above, a low friction layer or coating 33, e.g. low friction sacrificial plastic or even rolling wheels may be provided on the inner surface of the or each deployment arm, to provide a low-friction interface between the deployment arm(s) and the outer surface of the track 20, in use.

    [0023] It will be apparent to a person skilled in the art, from the foregoing description, that modifications and variations can be made to the described embodiments without departing from the scope of the invention as defined by the appended claims.
