Detailed Description of Specific Embodiments
Figures 1 and 2 show an adjustable stand assembly 20 for a towed vehicle (e.g. a trailer, caravan or boat) according to a preferred embodiment of the present invention. The adjustable stand assembly 20 comprises an adjustable stand 60 and a vehicle attachment means in the form of a stand mount 40. The stand mount 40 comprises a mount bracket 42 for attachment to the towed vehicle and a support bracket 50 releasably mounted to the mount bracket 42. The adjustable stand 60 is releasably and adjustably mounted to the support bracket 50. Figure 3 shows the mount bracket 42, which is essentially a U-section bracket having an elongate rectangular base 43 and first and second webs 44 extending from respective lateral edges of the base 43. The first and second webs 44 are spaced and substantially parallel to each other, and are substantially perpendicular to the base 43. The first and second webs 44 each include a pair of apertures 45 and 46, with the apertures 45 and the apertures 46 of the first and second webs 44 being respectively aligned. In the embodiment, the distance between the pair of apertures 45 and 46 in each of the first and second webs 44 is 100 mm.
The base 43 defines a vehicle mount portion of the mount bracket 42 for attachment to the vehicle, typically by welding or other suitable means. Alternatively, the base 43 can comprise apertures for attachment to the vehicle via bolts. The base 43 in use is preferably mounted to a downwardly facing (bottom) surface of the vehicle, and thus the first and second webs 44 will extend generally downwardly in use. The first and second webs 44 define a space therebetween in the form of a channel 48, which faces generally downwardly in use, which functions as a mount portion for receiving and mounting at least a portion of the support bracket 50 thereto. Figure 4 shows a U-shaped lock pin 70 for the adjustable stand assembly 20. The lock pin 70 comprises an intermediate section 72 and first and second arms 75 extending from respective ends of the intermediate section 72, and perpendicularly to the intermediate section 72. The first and second arms 75 are substantially parallel to each other and spaced apart by the same distance as the apertures 45 and 46 of the mount bracket 42, which in the embodiment is 100 mm. The first arm 75 comprises an aperture 76 at an end portion thereof distal from the intermediate section 72. The aperture 76 is adapted to receive a split pin therethrough in use. Figures 5 to 8 show the support bracket 50 of the stand mount 40. The support bracket 50 comprises a first section 51 adapted for releasable attachment to the mount bracket 42 and a second section 52 having a stand mount portion 53.
The first section 51 comprises a bar 54 which in the embodiment is a rectangular cross-section tube. The bar 54 will extend generally horizontally in use and comprises a top wall 55, side walls 56 and a bottom wall 57. The side walls 56 each comprise a pair of spaced apertures 58 and 59, with the apertures 58 and the apertures 59 of the respective side walls 56 being aligned. The apertures 58 and 59 are spaced apart by the same distance as the apertures 45 and 46 of the mount bracket 42, which in the embodiment is 100 mm. Two generally right triangular flanges 80 extend from the bottom wall 57 of the bar 54. A vertical side edge 81 of the flanges 80 is aligned with an end edge 82 of the bar 54, with the side edges 81 and the end edge 82 defining at attachment edge 83 for the second section 52. A cutout slot 84 is formed in the bar 54 adjacent the attachment edge 83. The cutout slot 84 extends from the top wall 55 of the bar 54 and downwardly to about halfway down the side walls 56.
The bar 54 is dimensioned to be received within the channel 48 of the mount bracket 42, with the cutout slot 84 left uncovered by the mount bracket 42. The bar 54 and the channel 48 are dimensioned such that the bar 54 can be readily received and removed from the channel 48 but the play therebetween is minimised.
The second section 52 is substantially similar to the mount bracket 42 and comprises a U- shaped bracket having an elongate rectangular base 85 and first and second webs 86 extending from respective lateral edges of the base 85. The base 85 is attached to the attachment edge 83 of the first section 51, with the first and second webs 86 extending in a direction away from the first section 51. The base 85 thus extends generally perpendicular to the bar 54, and thus extends generally vertically in use. The first and second webs 86 are spaced and substantially parallel to each other, and are substantially perpendicular to the base 85. The first and second webs 44 each include a pair of apertures 87 and 88, with the apertures 87 and the apertures 88 of the first and second webs 86 being respectively aligned. The apertures 87 and 88 in each of the first and second webs 86 are spaced apart by the same distance as first and second arms 75 of the lock pin 70, which in the embodiment is 100 mm.
The first and second webs 86 define a space therebetween in the form of a channel 53, which is generally vertical in use, which functions as the stand mount portion 53 for the adjustable stand 60.
Figures 9 and 10 show the adjustable stand 60 which comprises a stand body 61 having a complementary bracket 62 and a ground support arrangement 63.
The stand body 61 comprises an elongate receiving tube 64. The ground support arrangement 63 comprises a ground engaging means in the form of a base plate 65 connected to an internally threaded elongate shaft 95 (shown in Fig. 1) which is received in the receiving tube 64. The receiving tube 64 comprises an adjustment means therewithin, similar to that provided for a jack or jockey wheel, which allows the position of the threaded elongate shaft 95 relative to the receiving tube 64 to be selectively adjusted via a rotatable handle 66 disposed at an upper end of the receiving tube 64. Thus, the distance between the receiving tube 64 and the base plate 65 is incrementally adjustable. For example, receiving tube 64 can comprise a threaded elongate sheath (not shown) adapted to engage and move the threaded elongate shaft 95 relative thereto upon rotation of the handle 66. Alternatively, the adjustment means can be provided via a hydraulic means therebetween.
In other embodiments, the ground support arrangement 63 and receiving tube 30 may take a different form that provides height adjustment for the ground engaging means 65. The height adjustment may be incremental or continuous, manual or automatically controlled. In yet other embodiments, the base plate 65 can be replaced by a rolling ground engaging means, such as a caster wheel.
Figures 9 to 11 show the complementary bracket 62 which in this embodiment is an elongate generally U-section member 90 having an elongate rectangular base 91 and first and second webs 92 extending from respective lateral edges of the base 91. The first and second webs 92 are spaced and substantially parallel to each other, and are substantially perpendicular to the base 91. The first and second webs 92 each include a series of seven spaced apertures 93, with the apertures 93 of the first and second webs 92 being respectively aligned. In the embodiment, the distance between the adjacent apertures 93 in each of the first and second webs 92 is 50 mm. The webs 92 each include a longitudinal edge 94 which is distal to the base 91. The longitudinal edges 94 are welded to the receiving tube 64 such that the member 90 is generally parallel to the receiving tube 64. The member 90 is dimensioned to be received within the stand mount portion 53 of the support bracket 50. The member 90 and the stand mount portion 53 of the support bracket 50 are dimensioned such that the member 90 can be readily received and removed from the stand mount portion 53 but the play therebetween is minimised. In other embodiments, the complementary bracket 62 can be solid or take any suitable shape.
Mounting and use of the adjustable stand assembly 20 will now be described generally referring back to Figures 1 and 2.
In the preferred embodiment, the mount bracket 42 is attached to a bottom surface of the vehicle, with the channel 48 facing generally downwardly. The bar 54 of the support bracket 50 is then inserted within the channel 48 of the mount bracket 42, with the cutout slot 84 engaging a lifting web (not shown) of the vehicle as typically provided thereto. The apertures 45 and 46 of the mount bracket 42 are aligned with the apertures 58 and 59 of the bar 50, and the arms 75 of a first lock pin 70 are inserted through the aligned apertures 45, 58 and 46, 69 to lock the support bracket 50 to the mount bracket 42. A split pin (not shown) is inserted in the aperture 76 of the first lock pin 70 to secure the lock pin 70 to the mount bracket 42. As described above, the bar 54 and channel 48 are dimensioned to minimize play therebetween.
Securing the support bracket 50 in this manner to the mount bracket 42 positions the stand mount portion 53 of the support bracket 50 in a substantially vertical orientation. The complementary bracket 62 of the adjustable stand 60 is then inserted within the stand mount portion 53 of the support bracket 50. The apertures 87 and 88 of the stand mount portion 53 are aligned with any desired two apertures 93 of the complementary bracket 62, and the arms 75 of a second lock pin 70 are inserted through the aligned apertures 87, 93 and 88, 93 to lock the complementary bracket 62 to the stand mount portion 53 of the support bracket 50. A split pin (not shown) is also inserted in the aperture 76 of the second lock pin 70 to secure the lock pin 70 to the stand mount portion 53. As described above, the complementary bracket 62 and the stand mount portion 53 are dimensioned to minimize play therebetween. The adjustable stand 60 in the preferred embodiment is a jack assembly, which can be adjusted and operated mechanically or hydraulically. The adjustable stand assembly 60 can however be alternatively used with a jockey wheel adjustable stand.
It can be seen that the present invention provides an adjustable stand assembly which provides a number of options and advantages. Since the adjustable stand 60 is releasably mounted to the stand mount 40, the adjustable stand 60 can be released from the stand mount 40 and stored if desired. Also, different adjustable stands 60 can be readily mounted to the vehicle without having to remove the stand mount 40. The position of the adjustable stand 60 relative to the stand mount 40, and thus the distance between the adjustable stand 60 and the ground surface, can also be adjusted. Also, the support bracket 50 can be released from the mount bracket 42 and stored if desired. The intermediate section 72 between the arms of the lock pin 70 provides an easy grip for removal of the U-shaped lock pin 70 from the apertures if desired.
Modifications can also be made to the adjustable stand assembly 20. For example, the mount bracket can alternatively be a hollow tube and the bar can be dimensioned to be received within the hollow tube. A similar structure can be provided for the stand mount portion and the complementary bracket.
All parts of the adjustable stand may be manufactured from any suitable engineering materials such as aluminium, steel or heavy duty plastic. Another embodiment of the present invention is a towed vehicle comprising the adjustable stand 20 as described above, such as a trailer, caravan or boat.
Referring to Figs. 12 - 18 an adjustable stand mount 5a is provided for a towed vehicle comprising vehicle attachment means in the form of a bracket 15a and a stand body 20a releasably and adjustably mounted to the bracket 15a.
