Description

Improved mixing tool The present invention relates to an improved mixing tool which can be used to mix viscous materials such as plaster, cement, sand etc. Although there is a clear use in the construction industry, it is not necessarily limited to use in this industry.
The invention can also relate to a scoop or ladle, again with a view to use in the construction industry, which is hard wearing and easy to clean.
In the building and construction trade is often necessary to mix materials such as plaster, cement or sand etc. in quantities that do not require a full size free standing mixer. Increasingly, modern building materials are provided pre-bagged and require thorough mixing if the best possible results are to be achieved. The poor mixing of materials has been identified as being one of the most common causes of material failure.
Typically, trades people and DIY enthusiasts alike will utilise hand held paddle mixers in order to mix building materials easily. Typically, these paddle mixers comprise a shaft with a rigid, fixed position blade or paddle at one end and a means for rotating said shaft at the other end to the mixer. There are a number of configurations that the blade or paddle can take depending on the viscosity of the fluid to be mixed. In trade use the means for rotating the shaft is usually provided as an integral motor to provide a single unit, however for DIY use the shaft is usually adapted such that it attached to a standard power drill which will provide the rotation.
Most often, the mixer is made from a mild steel material, although other rigid materials can be used. Whilst the rigidity of the material works well for the mixing of viscous fluids such as cement, plaster or sand mixes problems generally arise when trying to ensure even mixing in the corners of a container as the blade is often unable to reach all of the way into edges depending upon the shape of the container. A related problem seen with blast mixers is that their blades or paddles can shatter if they come into contact with solid materials such as stones.
Another significant problem that is commonly encountered when using standard paddle mixers relates to the difficulty in cleaning the paddles or blades. This problem is particularly apparent for plaster mixing, as fresh plaster will set more quickly if it comes into contact with plaster that has already set. It is therefore essential that mixing tools are cleaned thoroughly after each mix. The standard manner of cleaning paddle mixers is to provide a sharp blow to the blade and/or shaft, for example with a hammer or other hard object, to remove the residual hardened material. Alternatively the paddle or blade can itself be hit off a hard surface, such as a wall, to dislodge any material that has hardened onto the paddle or blade. Whilst effective, repeat cleaning using these methods results in damage to the rigid blade, reducing the life of the mixer.
It is an aim of the present invention to obviate or mitigate some of the problems associated with traditional mixing tools.
According to a first aspect of the present invention there is provided a mixing device comprising; An engagement section, having at one end engagement means adapted to engage with a rotatable element; and At least one resiliently deformable mixing blade located at the opposite side of the engagement means, wherein the at least one resiliently deforrnable mixing blade is configured to deform under centrifugal force.
Advantageously, as the resiliently deformable mixing blade is flexible and is configured to deform under centrifugal force it will act as an impeller or rotor like device when the mixing device is rotated. The mixing blade will move from a first position when there is no rotation, outward to a second position when centrifugal pressure is applied via rotation. When the mixing blade is placed into a container of viscous fluid, the rotation of the blade results in fluid turbulence or mixing within said viscous fluid. In addition, as the blade is deformable it is easily able to mould into the shape of the container edges allowing for minimal input from the user.
Preferably, the engagement section is adapted to engage with a standard power tool.
This has the benefit of allowing the mixing device to be used along with standard products such as a power drill which are commonly owned by both tradesmen and DIY enthusiasts.
Optionally, the engagement section comprises a collar element for attachment to a rotatable shaft.
Another option is that the engagement section includes a shaft for attachment to a means for rotating said shaft.
Preferably the shaft is plastic coated.
Optionally, the mixing blade is in the form of a lobe.
Another option is that the mixing blade is in the form of a loop.
Providing the mixing blade in a loop shape allows fluid to move through the centre of the loop as well as around the sides.
Most preferably, at least one section of the loop is formed into a flange.
The advantage of one section of the loop being formed as a flange or flattened section is that it will act as a paddle, maximising motion and mixing within the fluid.
Preferably the mixing blade is formed from a rubber or rubberised material.
Alternatively the mixing blade is formed from a resilient, flexible plastic material.
In further alternative embodiments, the mixing blade is formed of a steel cable which steel cable is preferably housed in a casing of rubber or rubberised material or, alternatively, is housed in a casing of resilient, flexible plastic material. In this way, the mixing blade is flexible with an improved resistance to shear forces. The casing assists the mixing blade in operation as a steel cable alone would have a tendency to travel in a straight line without deform ing to the shape of the receptacle in which the material to be mixed is held.
Preferably the mixing device is provided with multiple resiliently deforrnable mixing blades.
Most preferably, the device is provided with two resiliently deformable mixing blades.
According to a second aspect of the present invention there is provided a scoop type receptacle for carrying fluid material comprising; a body portion having a bottom section, the front-most portion of which being adapted to allow material to be scooped into said receptacle, side walls and a back wall, wherein the receptacle is formed from a resiliently deformable material.
Advantageously, forming the receptacle from resiliently deformable material allows for easy cleaning and re-use. As the receptacle will deform and then return to its original configuration, any hardened on debris is removed by applying a force to deform the scoop causing the debris to splinter off the surface then allowing the scoop to return to it's original shape.
In order to provide a better understanding of the present invention embodiments will be described, by way of example only, and with reference to the following figures in which; Figure 1 is a schematic diagram of a mixing device according to the present invention; Figure 2 is a schematic diagram showing an alternate view of a mixing device according to the present invention; Figure 3 is a schematic diagram showing a view of the mixing device where the blades are deflected as they have been placed under centrifugal force; Figure 4 is a schematic diagram showing the back view of provided a scoop device according to the second aspect of the present invention; Figure 5 is a schematic diagram showing the top view of provided a scoop device according to the second aspect of the present invention; and Figure 6 is a schematic diagram showing the front view of provided a scoop device according to the second aspect of the present invention.
The preferred embodiment of the present invention is a mixing tool, as generally depicted in figures 1 to 3. The mixing tool I has a securing collar 2 which is provided with drill holes which extend through the collar 2.
Rivets 3 are passed through the drill holes to secure the collar 2 to a standard 8mm hexagonal shaft 4. The shaft 4 is itself plastic coated to reduce corrosion and is adapted to be fixed to a power drill (not shown).
On the opposing side of the collar 2 to the shaft 4, there are two mixing blades in the form of mixing lobes 5. In the preferred embodiment the lobes 5 are made from heavy duty reconstituted, reinforced rubber from recycled tyres, however it is envisaged that a range of rubberised plastics or other resilient flexible materials could be used be used. It is likely that the material selected to make the lobes 5 will be based on the viscosity of the fluid to be mixed, with more viscous fluids requiring stronger materials.
The preferred embodiment has the lobes 5 in the form of loops, which can best be seen in figures 2 and 3. One section of each loop is formed into a flattened section or flange 6. The flange 6 assists with mixing of a viscous fluid be increasing the surface area of the loop or lobeS In use, the hexagonal shaft 4 is fixed to a standard power drill (not shown) which acts to rotate the shaft as required. In the preferred embodiment a 24volt cordless drill is used. If there is no or minimal rotation, the lobes 5 hang downwards in use as can be seen in figures 1 and 2. This does allow for a level of mixing and can be useful for high density fluid mixing.
However, as the speed increases, for example to 300-1200 rpm, this results in a centrifugal force acting on the lobes 5 which causes said lobes to move upwards and outwards as best shown in figure 3. This provides a thorough mixing action drawing fluid from top to bottom.
Although the preferred embodiment utilises a cordless drill to provide rotation movement, it will be clear to one skilled in the art that an integral motor could be provided to provide an all-in-one tool. Furthermore, there may be cases where the shaft is not required and the collar may be attached directly to another rotating means.
Turning to the second aspect of the present invention, a preferred embodiment takes the form of a hand held scoop 7 or ladle for use in the building or construction trade to transfer quantities of fluids or mixtures, particularly for use in conjunction with flexible mixing tubs or trugs that are currently available. An example is depicted in Figures 4 to 6 which shows a scoop with a frusto-conical cross section. The scoop 7 has a curved base 8 with two side walls 9 and a back wall 10. The front section of the base 8 is adapted to allow for easy scooping and may be graduated. The side walls 9 prevent spillage of any fluid that is collected in the scoop 7.
The scoop 7 is formed from a resiliently deformable material, similar to the mixing blades of the first aspect of the invention. In the preferred embodiment this is a heavy duty flexible plastic. The flexibility of the material ensures that the scoop 7 is robust and easy to clean. To remove any hardened on debris the scoop can either be deformed slightly which causes the material to crack and flake off, or can be struck by or against a solid object with the same result.
Although the above embodiments are indicative of the invention, they should not be considered as limiting. In particular, it is envisaged that, as well as being useful for the mixing of building and construction products such as cement, plaster and sand, the mixing tool could also be used for small scale mixing, for example when mixing cake or food mixes or even for drinks mixing.
