Description

CONNECTING PROFILE AND METHOD FOR CONNECTING ELEMENTS
FIELD OF THE INVENTION
The invention relates to the connecting pro- file as defined in the preamble of claim 1 and to the method for connecting elements together as defined in the preamble of claim 12.
BACKGROUND OF THE INVENTION
Known from the prior art are different floor, ceiling and wall elements for both interior and exterior use. There exist e.g. wooden, ceramic, stony and plastic surface elements and those formed from a composite to be used as floor, ceiling and wall surfaces. The known surface elements may be used, depending on the material, in interior or exterior locations, e.g. in residential and public spaces, sanitary facilities, balconies, terraces, patios or in equivalent places.
Wood-plastic composite materials have pres- ently become more general in the manufacture of surface elements, thanks to their easy maintenance, tailor-made weather-resistance and new color palette.
Conventionally, the surface elements are linked together by using connecting pieces mainly made from metal or by screwing the elements to the battens. A problem in the known connecting methods has been that gaps remain between the elements. The gaps are problematic in interior spaces because dirt and dust are able to penetrate under the surface elements and cannot be removed therefrom. This weakens the usability of the elements. Especially in using separate connecting pieces in exterior use it has been perceived as a problem that, when the elements and the connecting pieces are made from different materials, they be- have in different ways as the ambient moisture and temperature varies. In such situations unfastening of the elements from each other, dilation/reduction of the gaps between them, rising of the surface made from the elements and breaking of the connecting pieces has taken place.
OBJECTIVE OF THE INVENTION
An objective of the invention is to disclose a new type of a connecting profile to be used in con- nection with elements formed from a composite material in order to connect them together. In addition, an objective of the invention is to disclose a method for connecting the elements together. SUMMARY OF THE INVENTION
The connecting profile and the method according to the invention are characterized by what has been presented in the claims.
The invention is based on a connecting pro- file to be used in order to connect elements formed from a composite material. According to the invention the connecting profile includes a connector arranged to be compatible with a matching connector of the ele¬ ments, and the connecting profile is substantially formed from the same material as the elements to be connected. In one preferred embodiment the connection between the connector of the connecting profile and the matching connector of the element is substantially tight, but not too tight for the sake of stretching and contracting due to heat and moisture of the material. In a preferred embodiment the connection has a small play.
A connecting profile means in this connection an elongated profile or means used for connecting and/or fastening at least two elements or pieces together. The dimensions of the connecting profile, such as the length and the height, and the shape, size and length of the connector may vary depending on the application. Preferably the dimensions of the connector of the connecting profile depend on the dimensions of the matching connector of the element. By the- connecting profile it is possible to fasten, connect and/or support elements and bear the load applied on the ele¬ ment .
An element means in this connection an elon- gated element, such as a board-type or plank-type element or one having an equivalent shape, or a slab-type element or an element of another shape. The element may be two- or three-dimensional. The board-type element may have e.g. rectangular, elongated parallelo- gram, square or equivalent shape. The element may have any size, depending on the purpose of use. The element may be a terrace, balcony, patio or an equivalent element. In addition, the element may be a wall, floor or ceiling element.
In one embodiment of the invention ■ the con¬ necting profile includes two projecting tongues as the connector, arranged to be compatible with matching connectors, i.e. grooves, of the elements in order to form a tongue-and-groove joint.
In one embodiment of the invention the con¬ necting profile includes two grooves as the connector, arranged to be compatible with matching connectors, i.e. projecting tongues, of the elements in order to form a tongue-and-groove joint.
In one embodiment of the invention the connecting profile includes one projecting tongue and one groove as the connector, arranged to be compatible with matching connectors, i.e. a corresponding groove and tongue, of the elements in order to form a tongue-and- groove joint. In this connection a tongue-and-groove joint means a connection for connecting adjacent elements, pieces and/or equivalent, preferably in this connection the element and the connecting profile, together. The tongue and groove may be situated on one side, multiple sides or each side of the element. In this connection a groove means an edged or a bit wedge-shaped channel in the middle of the edge in the direction of the height of the element or the connecting profile, extending for a desired distance in the lengthwise direction of the element or the connecting profile, and a tongue means the corresponding projection on the connecting profile or the element. In the context of this invention this definition also includes the so-called locking tongue and groove.
In one embodiment of the invention the connectors of the connecting profile are provided on substantially opposed sides of the connecting profile relative to each other on the cross section of the connecting profile, preferably at an angle of approximately 180 degrees to each other. In one embodiment the connectors are provided at an angle of approximately 90 to 180 degrees to each other on the cross section of the connecting profile.
In one embodiment of the invention between two connectors of the connecting profile there is pro¬ vided a link part that links them together. In one embodiment the connector is substantially inside the link part, e.g. a groove. In one embodiment the link part is solid in cross section. In one embodiment the link part is hollow.
In one embodiment of the invention the link part is arranged to have a height extending for the entire height of the element when the elements are placed against a base and the connecting profile is placed in connection with the elements, preferably be- tween the elements. In one embodiment the link part is arranged to have a height extending against the base on which the elements are mountable when the connecting profile is placed in connection with the elements. In one embodiment the link part is arranged to extend in the height direction to a level lower than the surface of the element when the connecting profile is placed in connection with the elements. In one embodiment the link part is arranged to have a height extending to the level of the surface of the element. In one embodiment the height of the link part is arranged to be not more than the height extending from the matching connector of the element to the surface of the element when the elements are placed against the base and the connecting profile is provided to link the elements together .
In addition to the connector and/or link part, the connecting profile may include other parts required for the purpose of use, such as parts facilitating the fastening or handling or other suitable and desired parts.

The connecting profile stretches and contracts according to thermal and moisture variations in the same way as the elements.
Thanks to the connecting profile according to the invention, it is possible to form a continuous surface consisting of the elements and the connecting profiles. The invention provides for the formation of a surface where there are substantially no gaps left between the elements. In its uniformity, the obtained surface looks attractive and vivid. By using different colors in the elements and the connecting profiles, various patterns may be created on the surface. Thanks to the invention, a floor area formed from the elements and connecting profiles is even and pleasant to walk on.
An extensive range of connecting profiles having different appearances may be made by the same compression mold.
The connecting profile according to the invention acts as a fastener by which the elements, e.g. the board elements, are connected and fastened together. In addition, the connecting profile acts as a load bearing and balancing structure, reducing point load and harms it may cause on the elements. The connecting profile provides a strong connection. In addition, curved surfaces may be formed from the elements by the connecting profile according to the invention, e.g. for round roadside waste bins.
