Abstract

A flexible rubber tile 1 has a recess 4 in a surface 3 connected by a through hole 7 with an opposite face 2, the through hole having a non-return valve mounted in it so that when reduced pressure or a vacuum is created in the recess, and means to create the reduced pressure or vacuum ceases operation, the reduced pressure or vacuum is maintained. This ensures that a curable resin on the surface 3 is allowed to cure until the tile is self- supporting while the reduced pressure or vacuum is maintained. <IMAGE>

Description

SPECIFICATION Bonding The invention relates to bonding an article to a substrate, for example a flexible article such as a rubber tile to a substrate such as a wall or windows.
According to one aspect of the invention there is provided an article to be bonded to a substrate having a surface for application to the substrate, a recess at the in use bonding interface, and means for exhausting air from the recess whereby to create suction which in use maintains the article in place.
The means may be a through hole in the article when the recess is in a face of the article.
The air may be exhausted by flexing the article towards the substrate so that the air is passed from the or each recess through the hole, which is then plugged. Alternatively the hole may include a nonreturn valve.
The or each recess may be in the substrate, the article being plane or substantially so.
According to a second aspect of the invention there is provided a method of securing an article to a substrate, comprising applying a surface of an article as hereinbefore defined to a surface of a substrate to provide a bonding interface after applying a curable adhesive to the article or substrate, creating a reduced pressure in the recess, and maintaining same until the curable adhesive has cured sufficiently to maintain the article in place.
During the bonding of a flexible rubber tile to a substrate using a two component epoxy resin, some means of holding the tile in place until the resin has cured is therefore utilised.
The tile may be held in place with a vacuum until sufficient cure has taken place in the resin so that the tile is self supporting.
The vacuum may be applied using a small vacuum pump or by an air venturi system.
When using the vacuum pump a simple nonreturn valve may be incorporated as a permanent part of the tile.
This would enable the vacuum source to be removed yet still maintaining a vacuum between the tile and the substrate.
Articles according to the invention are diagrammatically illustrated, by way of example, with reference to the accompanying drawings.
Fig. 1 is an elevational view of one embodiment of article in the form of a flexible rubber tile; Fig. 2 is a transverse sectional view of the tile of Fig. 1; Fig. 3 is a view similar to Fig. 1, of a second embodiment of tile; Fig. 4 is a transverse sectional view of the tile of Fig. 3; Fig. 5 is an enlarged sectional view of part of the non-return valve of Figs. 2 and 4 in one position; and Fig. 6 is a view similar to that of Fig. 5, in a second position.
Referring to the drawings, in which like parts are identified by like numerals, Figs. 1 and 2 show a flexible rubber tile 1 which has a planar face 2 which in use is the exposed face, and an opposite face 3 in which there is a recess 4 defined by a boundary edge 5 of the face 3. The base 6 of the recess 4 is connected with the face 2 by means for exhausting air from the recess 4 in the form of a through hole or passageway 7 in which there is a non-return valve 8.
The non-return valve 8, Figs. 5 and 6, comprises a body 9 housing a movable valve in the form of a reciprocable ball 10, the body 9 having a frustoconical valve seating 11 on which the ball 10 is received when no vacuum is created.
In use to secure the tile 1 to a substrate, not shown, a curable adhesive such as a twocomponent epoxy resin is applied to the surface 3, and the surface 3 is applied to the surface of a substrate to which it is desired to secure the tile, the two contacting surfaces providing a bonding interface.
The base 6 of the recess 4 is thus spaced from the substrate. A reduced pressure or vacuum is then created in the recess 4 by connecting a vacuum pump or air venturi system to the end of the hole 7 at the surface 2 and operating the pump or system so that the ball 10, which is initially on the valve seat 11 (Fig. 6) is lifted therefrom (arrow 'X') as air is exhausted, as shown in Fig. 5. When the pump or system is ceased operating, the ball 10 returns to the seating 11 (arrow 'Y') to maintain the vacuum between the tile 1 and substrate by preventing ingress of air. This vacuum is maintained until the resin has cured sufficiently to maintain the tile 1 in position on the substrate. The vacuum may then be broken, which may be necessary if the tile is flexible and which would flex towards the substrate under gravity while the vacuum is created.
Referring now to Figs. 3 and 4, the article shown therein is a tile 20 similar to that of Figs. 1 and 2, except that the single recess 4 of those Figs. is effectively split into a plurality of recesses 21 or voids interconnected by a plurality of branch passages 22 which are in turn connected with the through hole 7, in which the non-return valve 8 is situated.
Use of this tile 20 to form a system of substrate and tile bonded thereto is then similar to that described with reference to Figs. 1 and 2.
1. An article to be bonded to a substrate having a surface for application to the substrate, a recess at the in use bonding interface, and means for exhausting air from the recess whereby to create suction which in use maintains the article in place.
2. An article according to Claim 1, the recess being in the article, and the means comprising a through hole connecting the recess to another surface of the article.
3. An article according to Claim 2, which is flexible.
4. An article according to Claim 3, being a flexible rubber article.
5. An article according to Claim 4, comprising a plurality of discrete interconnected recesses in the surface.
6. An article according to any of Claims 2 to 5, including a non-return valve in the through hole.
