Abstract

The invention relates to a draining board comprising a basic plate of plastic and a cover sheet. The known draining board of this type sometimes has a rather short lifespan because moisture penetrates into the wooden basic plate at the join with sinks and/or walls. The invention has for its object to avoid the problem of moisture penetration and the associated reduction in lifespan, while manufacture of the draining board is still not too expensive. This object is achieved according to the invention in that the basic plate comprises recycled plastic. The use of recycling plastic makes the draining board less costly, contributes towards reducing the amount of plastic waste and makes the draining board durable because it is moisture-proof.

Description

DRAINING BOARD AND METHOD FOR MANUFACTURING SAME
The invention relates to a draining board as de¬ scribed in the preamble of claim 1.
Such a draining board is known from EP-0 028 862. It is proposed therein to manufacture the basic plate of wood, metal or plastic.
In practice the basic plate is made of wood because metal and plastic would be too expensive for such a solid plate. This draining board sometimes has a rather short lifespan because moisture penetrates at the join with sinks and/or walls.
The invention has for its object to avoid the prob¬ lem of moisture penetration and the associated reduction in lifespan, while manufacture of the draining board is still not too expensive. This object is achieved accord- ing to the invention in that the basic plate comprises recycled plastic. The use of recycling plastic makes the draining board less costly, contributes towards reducing the amount of plastic waste and makes the draining board durable because it is moisture-proof. The piece cut out at the position of the wash-basin in addition to possible pieces cut away from the draining board are recyclable as well as the draining board itself when for one reason or other it is discarded.
By draining board must be understood any work sur- face in which is received a wash-basin, optionally de¬ scribed as a sink, such as a kitchen draining board, a laboratory table top or a washstand surface.
The invention also relates to and provides a method for manufacturing a draining board according to the invention as designated in claim 4. It is noted that the manner of adhering a cover sheet to an already manufac¬ tured basic plate is per se known from EP-0 028 862.
Another method for manufacturing a draining board according to the invention is stated in claim 5. The above mentioned and other special features of the invention are elucidated in the description following hereinafter with reference to the drawings.
In the drawings: figures la, lb, lc show schematically three phases in the manufacture of a composite plate with use of the method according to the invention; figure 2 shows a section of a composite board with two different profile edges manufactured with use of the method according to the invention; figure 3 shows on larger scale detail III in figure 2; figure 4 shows a section corresponding with figure 3 of another embodiment of the profile edge; figure 5 shows a section of another profile edge; figure 6 shows a partly broken away and partly sectional perspective view of a profile edge in accor¬ dance with detail VI in figure 2; figure 7 shows a section of another embodiment of a device according to the invention; figure 8 shows on a larger scale a schematic view corresponding with figure 7 of a device applying another method according to the invention; figure 9 shows a section corresponding with figure 8 with another embodiment of the profile edge; figure 10 shows a section corresponding with figures 8 and 9 with yet another embodiment of the profile edge; and figure 11 shows yet another method according to the invention.
In figures la, lb and lc is shown how a draining board 1 according to the invention is manufactured. A basic plate 2 is supplied on a transporting device 50. Basic plate 2 consists of a mixture of ground recycled plastic which is preferably crumbled and a binding agent, preferably polyurethane. The recycled plastic can be made from plastic objects or components of objects no longer in use or can also consist of waste resulting during moulding processes. Such a basic plate is made commercially available under the name "Purenit-Platten" by the company Puren- Schaumstoff GmbH Kunststoffwerk Uberlingen/Bodensee. The glueing device 51 mounted above transporting device 50 applies glue 19 from a reservoir 55 onto the basic plate 2 with a roller 56, while this basic plate 2 is moved forward in the direction of arrow 57. In a subsequent phase (figure lb) a cover sheet 3 from a supply holder 58 arranged above transporting device 50 is arranged on the basic plate 2 provided with glue 19. Cover sheet 3 is taken out of holder 58 by co-acting transport rollers 52 which carry cover sheet 3 to the roller press 53 with which cover sheet 3 is pressed fixedly onto basic plate 2. Cover sheet 3 can be a foil, for instance a vinyl foil, as well as a sheet of plastic, veneer or metal.
Cover sheet 3 is arranged such that an edge part 4 there¬ of protrudes beyond the edge 6 of basic plate 2. The basic plate 2 with the cover sheet 3 partly connected thereto is then turned over (designated symbolically with arrow 54) and positioned on a table 7 against a stop 34 arranged at a determined distance from a mould 8. The latter has a profile corresponding to the desired profile of the profile edge 5. The basic plate 2 is then clamped fixedly onto table 7 with holding means 10 movable toward table 7 and securable in a desired position relative to table 7. In order to ensure that the outer surface 9 of edge part 4 everywhere lies properly against the mould 8, positioning means 11 are arranged which are movable relative to mould 8 and which can press edge part 4 into the mould 8. The space 12 bounded by the edge part 4 of cover sheet 3 and the edge 6 of basic plate 2 is now filled with a curable filler 13 which adheres to both plates. The filler 13 is supplied from a nozzle 38 of a filler supply device (not shown) . When the space 12 is wholly filled with filler 13 the supply is stopped and the filler 13 allowed to cure. When this has taken place, the finished composite plate 1 can be removed from mould 8 and from table 7 after the positioning means 11 and the holding means 10 have been moved into a rest position at a distance from the composite plate 1. Excess filler which may protrude from the surface 35 of basic plate 2 is later cut away.
Figure 2 shows a draining board 1 manufactured with the method according to the invention. This draining board 1 comprises two profile edges 5a and 5b. The pro¬ file edge 5a on the left in figure 2 protrudes upward relative to the upper surface 14 of the composite plate 1. A water-retaining edge 15 is hereby formed which prevents water flowing off draining board 1 during use. The basic plate 2 is the above mentioned "Purenit Plat- te" . Cover sheet 3 is a thermocuring plastic plate of a type which can be postformed. A property of this type is that chemically the plastic is not yet fully cured, whereby it can be made plastically deformable once again by heating it. The edge part 4 of cover sheet 3 is thus heated before being nestled against the mould 8.
Figure 2 shows that a mounting piece 16 is arranged on basic plate 2 in order to obtain a desired height of profile edge 5a. At the position of profile edge 5a the shape of the edge 6 of basic plate 2 is roughly adapted to the profile of profile edge 5a. Less filler 13 need hereby be used to fill the space 12 between the edge part 4 of cover sheet 3 and the edge 6 of basic plate 2. In this embodiment the surface of edge 6 transposes into connecting surface 18 via a transition surface 17 lying transversely of this connecting surface 18 of basic plate 2 to cover sheet 3. The advantage hereof is that glue 19 which during joining of cover sheet 3 with basic plate 2 is pressed out between these two does not connect plates 2 and 3 to each other any further than is desired (see figure 3) . Possible further connection is possible if the surface of edge 6 connects without a transverse transi¬ tion surface 17 to the connecting surface 18 between basic plate 2 and cover sheet 3, as shown in figure 4. When in this latter case different amounts of glue 19 are squeezed out between plates 2 and 3 at different loca¬ tions, as is the case in practice, the curving 20 of the cover sheet 3 where it transposes into the water-retain¬ ing edge 15 will not form a straight line in the longitu- dinal direction of the draining board 1. This is avoided by arranging the transverse transition surface 17.
A material which is particularly suitable as filler is polyurethane resin. This material cures very rapidly as a result of a chemical reaction between two components which are mixed immediately before the space is filled with the material.
In figure 5 is shown a profile edge 5 wherein cover sheet 3 is bent back toward the edge 6 of basic plate 2. The profile edge 5 hereby also has a finished appearance when viewed downward at an angle.
Figure 6 shows a device 29 for applying the method according to the invention. This device 29 is embodied for manufacturing a water-retaining edge as shown in figure lc. Corresponding components have the same refer¬ ence numerals and the same function as in figure lc. The holding means 10 are formed in this case by a plurality of suction cups 30, only one of which is shown. The suction cups 30 engage with vacuum on the top surface 14 of smooth plastic of cover sheet 3. The positioning means 11 are formed here by a first and a second comb-like member 22 and 23 respectively. The second comb-like member 23 protrudes into the first 22 and can be moved in the direction of arrow 24 by causing compressed air to flow into the hose 26 via the line 25. During this move¬ ment the cover sheet 3 is pressed into contact with the mould 8. The movement in opposing direction is caused by springs 31.
As described above, the protruding edge part 4 of the thermocuring plastic cover sheet 3 must be heated to make it deformable. In the embodiment of figure 6 the cover sheet 3 partially connected to basic plate 2 is laid for this purpose on the table 7 and the positioning means 11 such that the edge part 4 protrudes outside the positioning means 11. Using heating means (not shown) the edge part 4 is then brought to the desired temperature. The basic plate 2 with the cover sheet 3 is then pushed to the correct position on table 7 against a stop 34, whereafter the edge part 4 can be nestled against the mould 8 by the positioning means 11. Since the filler supply device can be a per se known device it is not shown here and the nozzle 38 thereof is only shown sche¬ matically.
Figure 7 shows schematically a preferred embodiment of the device 33 according to the invention, wherein the mould 8 can be moved by drive means (not shown) from the rest position 36 into the working position toward the basic plate 2, which plate 2 is clamped onto table 7 by the holding means 10, lies against the stop 34 and is provided with the cover sheet 3 which is made from post- formable thermocuring plastic. This embodiment contains heating means for the edge part 4. After edge part 4 has been brought to the desired temperature and is thus deformable once again, the said means 27 are moved aside in the direction of arrow 28, whereafter the mould 8 is nestled against edge part 4 and the processing is com¬ plete. The advantage of this device is that the basic plate 2 with the cover sheet 3 partly connected thereto does not have to be shifted relative to mould 8 after heating of the edge part 4, so that the risk of damage to cover sheet 3 during performing of the method is reduced. The positioning means 11 are formed in this embodiment by a profile 59 formed movably in relation to the mould 8 and guided therethrough. According to a preferred method the curable filler is injected under pressure into the space 12. As shown in figures 8-10, a filling channel 60 is drilled beforehand in basic plate 2 for this purpose. When basic plate 2 is arranged with the heated cover sheet 3 in the mould 8, a closing plate 65 is arranged which closes off the space
12 from the surroundings. A mouthpiece 61 of a nozzle 62 is connected onto channel 60. Nozzle 62 forms part of a per se known device for injection under pressure of curable two-component material. The space 21 is thus filled with the curable filler under pressure so that in addition to a good filling an additional pressing of edge part 4 in mould 8 is also achieved. The filling channel 60 may also be arranged in the closing plate 65 instead of in basic plate 2. According to figure 11 a cover sheet 3 is nestled on a mould surface 81 in a pressing mould 80 because it is sucked fast by means of an air suction channel system 82. When closed the pressing mould 80 is filled under pres¬ sure with the said mixture 83. The pressing mould 80 consisting of two parts is then opened and the manufac¬ tured draining board is removed.
