Description
LOAD LIFTING AND CONVEYING APPARATUS
THIS INVENTION relates to a load lifting and conveying apparatus. The invention has been devised particularly but not solely, for lifting and conveying furniture goods or other bulky household type goods.
Known devices for lifting and conveying furniture goods sand bulky items such as furniture, refrigerators or washing machines can be broadly classified into two separate categories. The first category includes the carton type trolleys which comprise a pair of handles and a blade portion and are supported by a pair of wheels. To lift and convey a load, the blade portion is positioned underneath the load and the trolley is tilted backwards to distribute the load between the blade and the handles.
The trolley can then be wheeled away. A variation of the carton trolley is the stair climbing trolley which is provided with assembly of wheels which enable the trolley to negotiate up and down stairs. The second broad category of devices for lifting and conveying furniture goods comprise the well known four wheel platform type trolleys whereby a load is lifted and positioned onto a trolley and is conveyed thereby.
A disadvantage with trolleys described above, is that neither allows for the easy lifting of loads and the ability to safely lift and convey loads which have an awkward configuration or an awkward weight distribution.
Additionally carton type trolleys are unsuitable for long loads while platform trolleys require a load to be physically lifted and positioned onto the trolley. This is unsuitable for heavy loads. A further disadvantage is that neither of the above categories of existing trolleys allows for conveyance of a load other than by means of the wheels. Thus surfaces which are unsuitable for wheeling such as soft ground, uneven ground, or raised obstruction do not easily allow for conveying loads with the previously known trolleys.
The invention has been devised broadly with the object to provide a load lifting and conveying apparatus which allows a load to be supported and restrained by the apparatus and conveyed thereby.

The embodiments are directed to load lifting and conveying apparatus for moving furniture or other bulky household type items although the apparatus need not be limited thereto.
In
the first embodiment
conveying unit of load lifting and conveying apparatus comprises a first portion 10, a second portion 11 and a handle means 12.
The first portion 10 is in the form of a horizontal elongate rectangular plate. The portion 10 is provided with retaining means in the form of a first and second upstanding flange 13 and 14 extending along the longitudinal edges of the portion 10. It should be noted however that flanges need not extend along the whole length of the plate and the height of each flange can vary along its length. Furthermore the spacing between the upstanding flanges 13 and 14 can be adjustable together with the height of each upstanding flange. The second portion 11 is positioned above the first portion 10 and is also in the form of an elongate rectangular plate having a support face. The plate is positioned such that the support face is substantially perpendicular to the base of the first portion. The first and second portions are spaced fro each other by means of an elongate support 15 to which each of the portions is secured. The spacing between the first and second portions 10 and 11 can be adjusted by movement of second portion 11 along the elongate support 15. Additionally the second portion 11 can be made to pivot around the tubular portion 15 so that the longitudinal axis of the second portion can be either parallel or vertical or at any other angle with respect to the longitudinal axis of the first portion 10. The first portion 10 is supported by a set of four wheels 16 mounted in a castor like fashion which are preferably in the form of opposed pairs to enable the load lifting and conveying apparatus to be free standing.The apparatus is further provided with a handle means 12 comprising a shank portion 12a extending from the elongate support 15 and a gripping portion 12b at the free end of the shank portion. The handle means 12 is connected to the load lifting and conveying apparatus such that the longitudinal axis of the shank portion is at an angle which is downwardly oblique to the elongate support 15. The handle means 12 can be a%tached to the elongate support 15 either permanently, or, as shown at Figures 4 and 5 to be removable therefrom.
In the latter alternative, the shank portion is provided at one end with a lug 18 which is engagable in a slot (17) on the elongate support. As shown at Figure 3 the elongate support 15 can be provided with a number of such slots thereby allowing the handle means to be adjustable in position over the length of the elongate support 15.
The second portion 11 is provided with a covering of cushioning material on the supporting face which is to be in contact with the load and the first member is provided with a similar cushioning material on the upper face of the plate which is in contact with the base of the load.
In use the load lifting and conveying apparatus as depicted above and as illustrated in Figure 3 is used by utilising at least two conveying units in an opposed relationship wherein a connecting member can connect the two units. The connecting member 20 can either be in the form of a rigid elongate member or in the form of a flexible member such as a link chain or cable and is attached to each of the units by any conventional means and can also be made adjustable in length. With the use of two units the flange 14 can be removed if desired as the load is now restrained by both of the conveying units.
To lift and convey a load such as a article of furniture or domestic utensil such as furniture, washing machines or refrigeration, a first conveying unit according to the invention is positioned along the edge of one side of the base of the load such that the edge is positioned on the upper face of first member 10 and restrained between flanges 13 and 14. Thus with articles such as tables, the feet of one end of the table would be placed on the upper face of member 10 and restrained between flanges 13 and JA. For other items such as refrigeration or washing machines, in the majority of cases these articles are provided with small adjustable feet which can also be placed on the upper face of the first member 10.In instances such as chests of drawers or other items which are not provided with feet the edge of one side- of the base of the article is positioned on the upper face of the first member 10. A second similar conveying unit is positioned on the other side of the load to be conveyed and again the edge of the base of the load is positioned on the upper face of the first member 10. Subsequent to positioning a pair of conveying units on each side of the load, an operator grips the handle means 12a and provides an upward force. By this action, the second member 11 is pushed hard against the side of the load and thus the load is firmly secured between the two conveying units.Thus by maintaining an upward force on the handle means 12a by each operator, the load can then be conveyed either by wheeling or conversely the load can be lifted from the ground without any fear of the load falling off the apparatus. For articles with a perfectly flat base, the two conveying units are linked by means of a chain cable or rigid connector and the article is positioned between the two apparatus and upon lifting of the handle means, it is firmly secured by the apparatus and can be lifted and conveyed to safety. The space between flanges 13 and 14 can be filled with a block of wood or other material to provide a substantially flat face.
The second portion 11 can be provided with a pair of spaced rods (not shown) each secured adjacent one end of the second portion and extending outwardly therefrom. The rods can be made adjustable in length and the spacing between the rods can be adjusted to suit the load. The rods are useful with conveying tall thin loads in that the is is positioned between the rods which are adjusted to secure the load between the rods.
In the arrangement illustrated in Figures 1 to 4, the handle means 12 extends downwardly and outwardly from the tubular portion. As illustrated in Figure 5, the handle means can be reversed so as to extend upwardly and outwardly.
The second embodiment as shown at Figure 5 is similar to the first embodiment and in the light of such the same reference numerals have been used in respect to corresponding components.
According to the second embodiment one conveying unit of the load lifting and conveying apparatus comprises a first portion 10 in the form of a pair of feet. The feet are provided with a retaining means 14 in the form of spaced apart ridges formed in a sawtooth pattern. The number, height and/or spacing of the ridges can be made adjustable.
The second portion 11 is positioned above the first portion 10 and is in the form of an elongate plate mounted to a backing member 23 which in turn is mounted between two pivot arms 25. The pivot arms are pivotally mounted to the tubular members 15 to which the first portion 10 is also secured. The pivot arms 25 are provided with adjustment means 27 for adjusting the position of the elongate plate back or forward. The backing member 23 to which the elongate plate is mounted can be pivotally mounted to the pivot arms 25 to allow the elongate plate to pivot about a substantially horizontal axis.
Furthermore the elongate member can be pivotally mounted to the backing member so that the elongate plate can pivot about an axis substantially orthogonal to that of the longitudinal axis of the backing member.
Additional tubular members 29 are provided to give strength and rigidity to the conveying unit.
The vertical spacing between the first potion 10 and the second portion 11 can be adjusted by providing adjustment means (not shown) such as telescoping capabilities for tubular members 15.
Similarly the spacing between the feet 10 and the length of the elongate plate 21 can be varied by any suitable means (not shown) such as telescoping capability for tubular members 29.
Handle means 12 are provided in the form of spaced apart handles. The handles are secured to the upper end of the tubular members 15. Typically the handle means are spaced vertically apart from the second portion 11. The vertical position of the handle means in relation to the second portion can be made adjustable. This feature would be particularly useful in the event that the second portion was lowered or raised to such an extent that the handles were not conveniently placed for the operator.
The first portion 10 is provided with a set of wheels for ground engagement. The wheels are mounted at the back of the first portion and one typically of the castor type.
The main differences between the apparatus of the second embodiment with respect to that of the first embodiment is firstly that the movements of the handle means 12 and second portion 11 have been interchanged, whereas in the first embodiment the lifting of the conveying unit by the .handle by the operator would effectively move the second portion towards the load until contact was made with one side of the load, the second embodiment allows the second portion to be moved into position before the units are lifted thereby allowing greater variation in load shapes to be accommodated. Secondly the form of the feet, and the lack of a second pair of wheels towards the front of the first portion, of the second embodiment enables an operator to place the first portion underneath the base of a load without having to lift the load so high as in the case of the first embodiment. The operator can therefore push down on the handles and push the conveying unit towards the load to fully engage the first portion and second portion with the load.
Various other changes and modifications can be made to the embodiments described without departing from the spirit or scope of the invention. For instance, the handle means may be in a fixed position (either extending upwardly or downwardly) rather than being reversible as described and illustrated in the foregoing embodiment.
