Description
TOOL FOR IG2RINTING PATTERNS IN COlICREvE This invention relates to the imprinting of patterns in concrete and in particular to a tool for imprinting such patterns.
The art of imprinting patterns in freshly laid concrete paving or flooring is well known. Known imprinting tools are generally made of metal or plastics in the form of an open framework which includes an arrangement of "V" shaped blades such that when the said tools are applied to the surface of freshly laid concrete and when pressure is applied to the top of the said'tools by means of punners, mallets, vibrators or the like, the said blades cause impressions or grooves to be made in the concrete in a manner such as to define patterns which simulate the appearance of brick, cobblestone, stone, tile, slate, slab or the like.
By repeated application of the said tools by placing one such tool adjacent to another such tool progressively over the surface of the concrete to be imprinted a plurality of impressions or grooves are made in the concrete. Thus in the prior art entire areas of concrete can be pattern imprinted. Generally, during the known process of imprinting patterns on concrete, workmen stand on the said tools while performing the operation of punning or vibrating or the like in order to avoid walking directly on the freshly laid concrete.
The term "freshly laid concrete" used herein is meant to denote concrete within a few hours of being laid or poured and before it has had time to set hard and therefore whilst the said concrete is in a plastic state.
Known tools as described hereinbefore are generally of such design as to be characteristically expensive, baulky and, when made of metal, heavy. Such known tools do not always provide the workmen with an ideal platform to stand on when performing the operation of punning or vibrating. Also such tools are not ideally suitable for patterns for which the said blade arrangement features large or expansive areas void of such blades. Furthermore, the design of such known tools are such that when said tools are damaged during use the repair of said tools is impracticable. This last mentioned fact and the general method of manufacture places limitations on the size of such known tools.
It is therefore desirable to provide an improved tool which is easy to handle, is well able to support workmen, is suitable for the design of expansive patterns, as defined by the blade arrangement, and which can be manufactured in a range of sizes and shapes from any particular master or master mould.
Furthermore, itis desirable that the said tool can be manufactured and assembled from component parts such that the said tool may be repaired at a relatively low cost by the replacement of such component parts. It is also desirable to provide means whereby the depth of the aforesaid impressions or grooves in the aforesaid concrete may be controlled or regulated.
According to one aspect of the present invention there is provided a tool comprising a platform, means for lifting which may be a handle or a plurality of handles or anchor points to receive lifting tackle, means which may be screws, bolts or the like for securing the said means for lifting to the topside of the said platform, an impression plate or a plurality of impression plates arranged, assembled and secured to the underside of the said platform in a two dimensional array of rows and columns in the concept of an X-Y matrix the said impression plates being characterised by a panel having a blade or a plurality of blades which may be"V" shaped the said blades being integrally manufactured, formed, cast or moulded on the underside of the said panel such that the said blades are perpendicular to the plane of the said panel the said blades being arranged such as to define a pattern which may be imprinted in the form of impressions or grooves in or on the surface of freshly laid concrete, and a plurality of fixings which may be screws bolts or the like for securing the said impression plates to the said platform.
According to another aspect of the present invention there is provided means for controlling the depth of the aforesaid impressions or grooves in the said concrete through the limiting effect of air pockets created by entrapped air within closed features of the aforesaid blade arrangement.
According to yet another aspect of the present invention there is provided means for controlling the depth of the aforesaid impressions or grooves in the said concrete through an alternative design of blade which is provided with shaped sides such that a pronouned fillet or taper limits the said grooves to the desired depth.

Referring to the drawings, Figures 1, 2 and 3 illustrate a tool comprising a platform 13, means for lifting 15 which may be handles (shown) or anchor points to receive lifting tackle (not shown), means (not shown) which may be screws, bolts or the like for securing the means for lifting 15 to the topside of the platform 13, a plurality of impression plates 14 at 14a, 14b, 14c, 14d, 14e and 14f, an impression plate 14 being characterised by a panel 18 having a plurality of blades 17, which may be "V" shaped, the blades 17 being integrally manufactured, formed, cast or moulded on the underside of the panel 18 such that the blades 17 are perpendicular to the plane of the panel 18 the blades 17 being arranged such as to define a pattern which may be imprinted in the form of impressions or grooves in or on the surface of freshly laid concrete, and a plurality of fixings 16 which may be screws (a plurality of four shown in each impression plate), bolts or the like for securing the impression plates 14 to the underside of the platform 13. Preferably the fixings 16 are characterised by countersink heads. Preferably the impression plates 14 are spaced from adjacent impression plates by a narrow gap 26. The gap 26 width is typically 0*5mm to 1.5mum.
Figures 4 and 5 illustrate an impression plate 14 prior to assembly for a clearer understanding thereof. A plurality of holes 25 (a plurality of four shown) are provided to receive the aforesaid fixings 16. As mentioned hereinbefore the the blades 17 may be "V" shaped although preferably they are characterised as illustrated by Figure 6 which shows a rounded fillet 19, tapered sides 20 and a blunt or flat end 21.
The aforesaid platform 13 may be made of any convenient material having strength adequate to support the weight of workmen and of such weight that the tool is portable.
Therefore, the said platform 13 may be of laminated wood, blockboard, plywood or the like. Preferably the said platform 13 is rectangular or square, the precise size and shape being defined by the size, shape and plurality of the aforesaid impression plates 14 which are secured to the underside of the said platform as described hereinbefore. The platform 13 thickness is typically 12mm to 30mm.
Preferably the aforesaid impression plate 14 is cast in aluminium or moulded in plastics by established and known methods. It is not regarded as necessary to described such known methods of casting and moulding.
Preferably the said impression plate 14 is rectangular or square, the precise size and shape being defined by the specific arrangement of said blades 17 selected. The said blade 17 depth is typically 6mm to 17mm. The said flat end 21 width is typically 1mm to 8mm. The said panel 18 thickness is typically 2mm to 6mm.
The said handles 15 can be made in any convenient design and made of any convenient material such as wood, metal, plastics, rope or the like.
The use of a tool according to the present invention will now be described as illustrated by Figure 7. Preferably the freshly laid concrete 41 is levelled, colouring material being applied to the surface of the said concrete if desired and preferably a thin sheet of plastic material 42 is laid on the surface of the said concrete prior to positioning the tool. The tool is positioned as desired and the blades 17 are forced into the said concrete 41 by the application of punners, mallets, vibrators or the like (not shown) to the topside of the platform 13.
An impression or groove 43 so formed in the freshly laid concrete 41 is of a depth which is typically from one quarter the depth of the blade 17 to a full depth of the said blade 17 as desired.
During the formation of the aforesaid impressions or grooves 43, air pockets formed from the entrapped air within the closed features or arrangement of blades 17 surrounding the spaces 50 act against the movement of the blades 17 into the said concrete thereby providing means of controlling the depth of the grooves 43 formed in the said concrete and also providing a means of control whereby the aforesaid panels 18 may be prevented from causing undesirable impressions or grooves in the areas of concrete between the grooves 17 such as may be caused by the aforesaid gaps 26 or the heads of the aforesaid fixings 16 when the blades 17 are forced to their full depth into the said concrete. It is understood that some air will escape via the aforesaid gaps 26 and open features or arrangements of blades 17.
The aforesaid "closed features" and "open features" of the blade arrangements are to be described hereinafter.
It is preferred that when the platform 13 is made of the aforesaid preferred materials such as laminated wood , blockboard, plywood or the like the said platform 13 may slightly flex, according to the natural tendancies of the material selected, when subjected to the weight of workmen such that the tool conforms to shallow undulations of the surface of the aforesaid concrete.
Furthermore the thin sheet of plastic material 42 presses on the said freshly laid concrete in such way as to form rounded edges 51 in the said concrete which enhance the finished appearance of the said concrete, as do also the impressions formed in the said concrete by the aforesaid blunt or flat ends 21 of the blades 17.
The aforesaid tapered sides 20 of the blades 17 make easy the release of the blades 17 from the impressions or grooves 43 when the tool is removed from the said concrete.
The aforesaid gaps 26 between impression plates 14 are provided as desired so that the aforesaid fixings 16 are not subjected to shear stresses,in the direction of the plane of the aforesaid panel 18, such as may occur if adjacent impression plates are assembled and secured to the platform 13 with said adjacent impression plates in contact with each other.
The pattern of impressions or grooves formed by the use of a tool according to the present invention on the surface of freshly laid concrete as described hereinbefore provides a simulated effect of brick, cobblestone, stone, tile, slate, slab or the like according to the arrangement of blades selected.
Figure 8 illustrates the pattern that would result fron the use of a tool provided with the specific blade arrangement shown in
Figures 2 and 4.
Evidently the arrangements of blades as described herein may include closed features and open features. Examples are illustrated by Figure 10 wherein the blade members surrounding the panel area 70 represent closed features whereas the blade members partially surrounding the panel area 71 represent open features. It is further understood that open features of the blade arrangement of an impression plate may become closed where an impression plate on a tool is located adjacent to another impression plate such as in the case of the blade members surrounding the panel areas 72.
Additional embodiments as now to be described have been represented mainly diagramatically in order to permit a clearer understanding thereof. Furthermore, in view of the description given in the foregoing for a specific embodiment it is regarded as unnecessary to mention some of the details in association with each of the embodiments since it is clear that they may be employed as a tool for the purpose of imprinting patterns on or in the surface of freshly laid concrete and that they come within the scope of the present invention.
According to one embodiment, air vents are provided to release the aforementioned air entrapped within the aforesaid spaces 50.
Such an air vent is provided by means of a first hole 52 in the panel of the aforesaid impression plate 14 and a second hole 53 in the aforesaid platform 13. Tne said hole 52 and hole 53 are co-centred, positioned and arranged such as to be aligned as illustrated by Figure 9. The air vents as described herein may be provided as desired at any location on the tool where the particular arrangement of blades selected is likely to entrap air during the process of imprinting patterns on or in freshly laid concrete as described hereinbefore. As an example
Figure 10 illustrates where a plurality of air vents may be located for a specific arrangement of blades, the location of the air vents being shown by the location of the said first holes 52. The diameter of the first hole 52 is typically 1mm to 8mm.The diameter of the second hole 53 is typically 9mtn.
According to one embodiment means are provided whereby the depth of the aforesaid impressions or grooves may be controlled as illustrated by Figures 11 and 12. Figure 11 shows a blade 54 provided with primary tapered sides 55 and secondary tapered sides or fillets 56 the said tapered sides 55 having a more pronounced taper than the said tapered sides 56. It is evident from Figure 12 that when during the process of imprinting impressions or grooves the lower end of the secondary tapered'sides:or fillets 56 reach the aforementioed groove 43 in the aforesaid freshly laid concrete a greater force is needed to drive the blade 54 any deeper into the said concrete.
At that point in the aforementioned process of imprinting a workman has a clear indication that the said grooves 43 are of the desired depth from the greater resistance met.
It is evident that the depth of the said impressions or grooves is determined by the point 58 at which the transition from the primary tapered sides 55 to the secondary tapered sides or fillets 56 occurs.
An impression plate as described hereinbefore may be provided with any appropriate arrangement of blades as desired.
Preferred arrangements of said blades are selected such as to form.impressions or grooves on or in freshly laid concrete to simulate brick, cobblestone , stone, tile1 slate1 slab or any like pattern. Preferably, such said arrangements of blades as may be included in the design of a specific impression plate represent a repeatable unit of the pattern to be imprinted.
The arrangement of blades for the impression plate shown in
Figure 4 is an example of an arrangement of blades representing a repeatable unit of a pattern (a tile pattern) and the arrangement of blades for the impression plate shown in Figure 13 is an example of an arrangement of blades representing another repeatable unit of a pattern (a cobblestone pattern) where the said unit of the pattern is the smallest repeatable unit of the pattern. The size and shape of a particular impression plate is defined by the specific arrangement of blades selected as mentioned hereinbefore, said impression plates being preferably rectangular or square. Generally, the said impression plates are typically 200mm to 360mm long by 200mm to 360mm wide.
In order to provide further example herein1 Figure 13 shows the underside of an impression plate 29 which is provided with an irregular arrangement of blades 30 which are designed to imprint a simulated cobblestone pattern. Figure 14 shows a tool provided with a small platform 31, an impression plate 29 and a suitable handle 32 (a length of dowel is shown) the said tool being suitable for use as a hand tool to imprint areas of freshly laid concrete where such areas are inaccessible to the larger tools. Figure 15 shows the underside of a tool provided with a plurality of nine identical impression plates 29 at 29a, 29b, and so on.
The term "repeatable unit of a pattern" as used herein is meant to denote that element or part of a pattern which defines the said pattern such that the said element or part of the said pattern may be placed or imprinted adjacent to an identical element or part of the said pattern in repeated steps to extend the said pattern over an area.
According to the preferred embodiments a plurality of identical impression plates are secured to the underside of a platform in an arrangement of rows and columns or two dimensional array which is conceptually in the form of an X-Y matrix.
The arrangement of impression plates shown in Figure 2 is an example of a specific arrangement in which a plurality of six impression plates 14a, 14b, 14c, 14d, 14e and 14f may be said to be arranged in a formation such that there is a first row of impression plates 14a, 14b, 14c adjacent to a second row 14d, t4e, 14f and such that there is a first column 14a, 14d a second column 14b, 14e and a third column 14c, 14f, the whole arrangement thereby representing a 2x3 array or matrix of impression plates.It should be readily understood that various embodiments of the tool may be provided with different arrangements of impression plates including the preferred arrangements listed in the table as follows:
