- mixing device 10 is comprised of a flexible,, generally rectangular sheet 11 gathered at the four corners 12 so as to form a generally rectangular basin 13 having folded-up sides 14.
- the sheet material is impervious and is sufficiently stiff to retain the general basin shape when the device is assembled and is arranged on a supporting surface.
- folded-up sides 14 causes folds of excess material at each of the four corners 12 which are bunched into elongate gathered- formations 15. As shown in
- each of formations 15 is attached to a handle 16.
- handle 16 is comprised of a gripping portion adapted to fit the hand of a user and an attachment portion adapted to connect to the formation 15.
- Preferred ratios of the height of the sides 14 to the length of the basin lie in the range of between 1 to 3 and 1 to 5.
- the dimensions of the basin are preferably chosen such that a typical bag of dry-mix mortar or concrete can be accommodated for mixing as described below.
- Preferred ratios of the volume of the basin to that of a standard proprietary bag of dry-mix mortar or concrete lie in the range of between 2.5 to 1 and 4 to 1.
- handle 16 is formed from an injection moulded polymer . having a gripping portion 22 and a hinged retaining portion 23 provided with projecting section . 24,
- the material of formation 15 in this form of the handle is fed through the handle opening 25 and thence through opening 26 after which hinged retaining portion 23 is rotated to enter opening 26 trapping the material of formation 15.
- the hinged retaining portion may be locked in this position by means of for example, screws or rivets so as to firmly attach formation
- a handle plate 27 and a retainer plate 28' are moulded into two portions comprising a handle plate 27 and a retainer plate 28'.
- a suitable length of the material of formation 15 is first fed through handle opening 29 and drawn through upper gap 30 into first holding aperture 31.
- the material is then drawn around the base of handle plate 27 and drawn through lower gap 32 into second holding aperture 33.
- Retainer plate 28 is then assembled to handle plate 27 by for example, mating arrays of holes 34 and snap-fit lugs 35 so as to attach formation 15 firmly to handle 16 as shown in Figure 4A.
- handle 16 is in the form of moulded handle plate 35 and retainer clip 37.
- the outer end of the material of formation 15 is formed into a ⁇ ' shape (as shown in Figure 5A) .
- the base of the *U f is then fed through slot 38 of the handle plate 36 far enough to engage retainer clip ' 37 with the leg 39 of the O" by means of gap 40.
- Retainer clip 37 is larger than slot 3B thus trapping the material of formation 15 when this is pulled back to seat clip 37 against handle plate 36 as shown in Figure 5A.
- a moulded handle 16 having a gripping portion 50 and a retaining portion 51.
- Handle 16 is further provided with dowel 52 which nests in recess 53 when the handle is attached to gathered formation 15.
- the material of gathered formation 15 is fed around dowel 52 as shown by dashed path 54.
- the outer end 59 of formation 15 Is pulled to pass through scalloped ' opening 55 as dowel 52 is pushed into recess 53, effectively trapping the material of formation 15 between dowel 52 and the edge 56 of opening 55.
- a suitable tying means 57 such as for.
- a cable tie is then inserted through holes 58 and tightened to compress the material of gathered formation 15 into recess 60,
- the path of . the material of the gathered formation 15 is such as to form a sharply folded region- over a load bearing edge or member.
- the remainder of the outer portion of the formation is further constrained in a manner to provide sufficient additional friction to prevent the material pulling from the handle when the device is in use.
- a fifth preferred form of a handle according to the invention as shown in Figures 7A and 7B r there is provided a moulded handle 16 having a gripping portion 70 and a retaining portion 71. Gripping portion 71 is formed so as to provide a wedge-shaped cavity 72 having apertures communicating with the central portion 73 and the underside 74 of handle 16. Preferably, cavity 72 is wedge-shaped in both length and width. Handle 16 is further provided with a wedge plate 75 adapted for insertion into cavity 72 and so dimensioned as to leave a gap between the surfaces of wedge plate 75 and cavity 72 when assembled as shown in Figure 7B.
- the material of gathered formation 15 is firstly fed upwardly through the aperture at the underside 74 of handle 16 and through cavity 72 so as to project into central portion 73 sufficient to allo the outer end 76 of gathered formation 15 to be folded over and pushed back downwardly into cavity 72.
- Wedge plate 75 is then inserted into the loop 77 now formed by gathered formation 15 and both the loop, of material and the wedge pulled downwardly into cavity 72 until firmly wedged in the cavity.
- The. forming of the basin, its depth and hence its other relative dimensions for a given sheet of material is determined by the manner of gathering the material at the four corners prior to the attachment of the handles.
- the sheet of material is laid out flat on a suitable surface.
- two points 80 lying equidistant along each of the edges from a corner 8l of the , sheet 82. are initially clamped or weighted down so as to maintain this initial position.
- two further points 83 and 84- lying along each edge, again equidistant from the corner by approximately at twice the distance as for point 81 and 82, . are pulled together and the material so gathered tied with, for example, a self adjusting cable tie 85.
- the effect is to draw the material adjoining the tied points upwardly relative to the middle of the sheet thus forming side-like formations surrounding a base portion; in effect approximating a basin.
- the material lying between, the tied point and the corners may now be gathered for feeding through, and attachment to the handles.
- material 11 and handles 16 may conveniently be bundled into a suitable container for transport and storage, such as for example in a polythene bag or in a canister such as a paint tin.
- the device In use the device is spread out on a suitable surface to form the basin 13; typically this will be the floor or ground close to where the mortar or concrete mix is to be used. A bag of dry-mix mortar or concrete is then deposited in the basin. Alternately smaller quantities of ingredients may be placed in the basin as desired.
- Water ' is then added in the desired or recommended quantity and the mixing process follows according to a first • preferred sequence.
- Two people each grasp tw.o adjoining handles allowing the bulk of the weight of the ingredients to remain supported on the floor or ground.
- One person (the first person), commences with either the right or left hand to tug upward on the handle in that hand thus causing the ingredients to be displaced towards the second person.
- the first person repeats this action with the other hand and then continues the sequence for each hand, tugging • upward and lowering the handles a number of times.
- the second person now duplicates this procedure. Both persons may continue to alternately repeat the process as required.
- the mortar or, concrete can be carried in the basin and poured out into its desired location.
- a single person may effect the mixing process after preparing at -least one but preferably two suitable hooks from a support at the height of approximately one meter and separated (in the case of two hooks) by approximately the width of the basin.
- mixing may be effected with two handles supported from the one hook, for be-st results, two handles should each be supported by its own hook.
- the remaining two handles are then grasped by the single person. Again the bulk of th weight .of the ingredients placed in the basin remains supported on the floor or ground as the, single person now alternately raises and lowers his or her two handles.
