Abstract
The invention relates to detachable, flat components (10, 12) that can be fastened to each other, in particular floor covering components. Each of said components has an edge region and said regions fit together by the displacement of the components in relation to one another, in such a way that the components, which lie on a common plane, are protected against becoming detached on said plane. The edge regions are configured as projections (14, 16), which lie one above the other in relation to their common plane when fastened to each other, in such a way that the components can be fastened to each other by means of an essentially linear relative displacement that is perpendicular to the common plane.

36. A generally flat component for covering a substantially-planar substrate, comprising:
-
a generally flat body having an upper surface and a lower surface, and a projection laterally extending from the generally flat body and having an upper surface and a lower surface, wherein one of the upper and lower surfaces of the projection has a substantially concave recess closest to the generally flat body and a substantially convex elevation closest to a terminal end of the projection and the other of the upper and lower surfaces of the projection extends in a substantially flush manner with the corresponding upper or lower surface of the generally flat body, wherein at least one engagement surface is defined on each of the recess and elevation of the projection and each engagement surface extends generally perpendicularly to an extension direction of the projection, the engagement surfaces being configured such that; the engagement surfaces are bringable into a form-fit engagement with a second generally flat component having a complementarily-formed projection, the projections of the respective generally flat components are disposable one on top of the other in the form-fit engagement, and the respective engagement surfaces prevent the engaged components from separating in a direction parallel to the extension direction of the projection, wherein at least two of the engagement surfaces have an undercut defined thereon, the undercuts being configured to be passed over, while at least one of the recess and elevation undergoes elastic deformation, by respective oppositely-directed undercuts formed on the corresponding engagement surfaces of the to-be-engaged complementary projection when the two components are engaged by moving the components relative to each other in a direction substantially vertical to the extension direction of the projection, and wherein the respective undercuts are configured to detachably-secure the two engaged components from separating in the direction vertical to the extension direction of the projection. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A kit for covering a generally-flat substrate by detachably-attaching a plurality of generally-flat components, the kit comprising:
-
a first generally-flat component comprising; a body having an first-generally planar surface extending in parallel with a second generally-planar surface, a vertical height being defined between the first and second generally-planar surfaces and a projection laterally extending from the body, the projection including a first generally-planar surface extending in a planar relationship with the first generally-planar surface of the body and a second surface having a generally concave recess disposed closest to the body and a generally convex elevation disposed closest to a terminal end of the projection, the elevation having a vertical height that is less than the vertical height of the body, a generally-flat second component comprising; a body having an first-generally planar surface extending in parallel with a second generally-planar surface, a vertical height being defined between the first and second generally-planar surfaces and a projection laterally extending from the body, the projection including a first surface having a generally concave recess disposed closest to the body and a generally convex elevation disposed closest to a terminal end of the projection, the elevation having a vertical height that is less than the vertical height of the body, and a second generally-planar surface extending in a planar relationship with the second generally-planar surface of the body, wherein the projections of the first and second components are configured to provide a form-fit engagement when pressed together with the projections of the first and second components being disposed one on top of the other, the respective recesses and elevations being configured to detachably-secure the first and second components against separation of the first and second components in a direction parallel to the extension direction of the projections and the projections being configured such that the first surfaces of the first and second engaged components extend in a flush manner and the second surfaces of the first and second engaged components extend in a flush manner, and wherein the first and second components each have at least a first engagement surface, which extends generally vertically between one planar surface of the body and the recess of the projection, and a second engagement surface, which extends generally vertically at the terminal end of the projection between the other planar surface of the body and the elevation of the projection, the first and second engagement surfaces of the first component each including at least one of a convex undercut and a concave undercut configured to be passed over, while undergoing elastic deformation of at least a portion of the projection, by at least one oppositely-directed undercut formed on the corresponding first and second engagement surfaces of the second component, the respective undercuts being configured to secure the first and second components, when in the form-fit engagement, from separating in a direction vertical to the extension direction of the projections. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
