Definitions

  • the invention concerns a floor mat as used, in particular, in entrance areas of department stores, theatres, hotels and other public walking areas.
  • a floor mat of this kind usually covers a rather large area. It must be removable for cleaning purposes.
  • a floor mat according to the generic clause of claim 1 is known from DE 44 06 093 A1 .
  • the connecting profile consists of two coupling rods connected by a web, each coupling rod having essentially cylindrical shape.
  • the end-to-end coupling grooves are also of essentially cylindrical shape, i.e., have circular cross section, each coupling groove of a pair of neighbouring rails accommodating one of the coupling rods of a connecting profile.
  • the connecting profile is in each case to some extent rotatable against the rail such that the floor mat can be rolled up. Due to the coupling rods being full cylinders the coupling grooves take up much space in the lateral direction.
  • the upper surfaces of the rails must either have broad margins which are bare, carrying no wiper material or similar, or they have, as is the case with the prior art floor mat, great overall height because the coupling grooves are arranged under a groove for anchoring a strip of wiper material.
  • US 5 157 804 A shows a floor mat where metal connecting profiles have coupling grooves for accommodating coupling rods laterally extending from rails which consist of polymeric material.
  • the connecting profiles are of necessity rather broad in this case, such that the strips of wiper material carried by the rails are flanked by broad bare metal strips.
  • a floor mat where a connecting profile comprises coupling rods of roughly elliptic cross section whereas the coupling grooves in the rails are somewhat larger with a D-shaped cross-section.
  • This solution allows limited rotation of the connecting profile against the rail but the relative position of these parts is not precisely controllable, as their connection allows some lateral and vertical play in addition to the rotational degree of freedom.
  • the configuration of the floor mat is not precisely fixed and relative motions of its parts which may cause clatter, wear and even damage cannot be excluded.
  • the lateral extension of the coupling groove is little more than half of that of a comparable cylindrical coupling groove.
  • the groove for the wiper material on the upper surface of the rail can therefore extend close to the lateral boundary of the upper surface.
  • the rails can be used with different connecting profiles such that different kinds of floor mats can be built from rails of the same type and the characteristics of a single floor mat varied over its extension by the use of different connecting profiles alone.
  • a lower limit angle limiting the angle between the upper surfaces of neighbouring rails can be determined by an appropriate choice of connecting profile, allowing a stiff connection, i.e., a lower limit angle of 180°, as well as a variety of smaller lower limit angles of, e.g., between 170° and 120° which makes it possible to roll up the floor mat into a coil of larger or smaller diameter for easier removal, transport and storage with upper surfaces of the rails, which usually carry wiper material, on the inside.
  • Both the rails and the connecting profiles can be produced in a simple and cost-effective way, preferably by extrusion.
  • the floor mat shown in the figures, in particular, in Fig. 1 and Fig. 2 comprises a plurality of parallel rigid rails 1 arranged side by side, where each rail is a metal profile of constant cross section produced by extrusion.
  • the metal is aluminium.
  • Each rail provides a rectangular upper surface extending in a longitudinal direction and a lateral direction perpendicular thereto.
  • the length of a rail 1 is usually between 0.5 and 2 meters, its breadth a few centimetres, normally between 2cm and 10cm.
  • Each rail 1 comprises two side bars 2 of roughly rectangular cross section with upper surfaces forming margin strips 3 which in use are essentially horizontally oriented, facing upwards.
  • FIG. 1, 2 show only part of a floor mat with rails 1 and connecting profiles 7a, 7b. Whereas the rails 1 are of the same design the connecting profiles 7a, 7b belong to different types. Usually a single connecting profile 7a, 7b which is only slightly shorter than the rails 1 is used in each case but a sequence of shorter connecting profiles which follow, separated or not by gaps, upon each other in the longitudinal direction may be employed as well.
  • Each side bar 2 is laterally bounded on an outside by a plane lateral face 8 which is perpendicular to the upper surface, i.e., vertical during use, and is interrupted by a coupling slot 9 which widens into a broader coupling groove 10 provided in the interior of the side bar 2.
  • the connecting profile 7a or 7b comprises two coupling rods 11, 11' ( Figs. 3 , 4 ) of corresponding cross sections each of which is accommodated in one of the coupling grooves 10, 10' of two neighbouring rails 1, 1' and which are connected through the coupling slot 9 of rail 1 and the opposite coupling slot of rail 1'.
  • the connecting profiles 7a, 7b are ( Figs. 1, 2 ) fixed in the coupling grooves 10 by fixing clips 12a, 12b which have been inserted into them and are arranged, e.g., between first ends of the coupling grooves 10 and an end of the connecting profile 7a; 7b, preventing the latter from escaping from the coupling grooves 10 at the first ends thereof.
  • Such fixing clips can also be used in other sections of the coupling grooves 10 for fixing shorter connecting profiles of, e.g., a length of 5cm, at desired positions, preventing them from being displaced in the longitudinal direction.
  • the connecting profiles can be arranged in such a way that they are separated by gaps in the longitudinal direction and that the profiles and gaps are aligned in the lateral direction and kept in their positions by fixing clips.
  • the coupling rods 11, 11' ( Figs. 3, 3a, 3b ) are directly connected.
  • the coupling rod 11 exhibits, on the side facing the coupling slot 9, a cylindrical convex circumferential surface 13 which is interrupted by a strip where the coupling rod 11 is joined to the other coupling rod 11'.
  • the said strip is a concave rear surface comprising a first stop surface 14 which is plane and extends from an upper edge of the convex circumferential surface to a cylinder axis 15 and an equally plane second stop surface 16 which extends from a lower edge of the convex circumferential surface 13 to the cylinder axis 15.
  • the first stop surface 14 and the second stop surface 16 include a stop surface angle ⁇ which is greater than 180°, in the example close to 195°.
  • the coupling rod 11 has essentially the shape of a cylinder sector with an opening angle equal to the stop surface angle ⁇ .
  • the second coupling rod 11' is of the same shape, its cross section being a mirror image of the cross section of the first coupling rod 11.
  • the coupling rod 11 is accommodated in a coupling groove 10 of the rail 1 and the coupling rod 11' in a coupling groove 10' of the neighbouring rail 1'.
  • the coupling groove 10 is bounded, on the side of the lateral face 8, by a cylindrical concave circumferential surface 17 which is interrupted by the coupling slot 9. On the opposite side it is bounded by a bottom surface which comprises a first limit surface 18 which extends from an upper edge of the convex circumferential surface 17 almost to the cylinder axis 15 and a second limit surface 19 which extends from a lower edge of the convex circumferential surface 17 almost to the cylinder axis 15.
  • the second limit surface 19 is parallel to the lateral face 8 of the side bar 2 whereas the first limit surface is inclined with respect to the same, the first limit surface 18 and the second limit surface 19 including a limit surface angle ⁇ of 195°.
  • the first limit surface 18 and the second limit surface 19 are separated by a narrow flute 20.
  • the concave circumferential surface 17 bounding the coupling groove 9 and the convex circumferential surface 13 of the coupling rod 11 are coaxial, with the common axis being the cylinder axis 15.
  • the radius of the convex circumferential surface 17 is only slightly smaller than the radius of the concave circumferential surface 13 such that it abuts on the latter.
  • the stop surface angle ⁇ is equal to the limit surface angle ⁇ or nearly so, the coupling rod 11 fills the coupling groove 10 virtually completely, the first stop surface 14 abutting on the first limit surface 18 and the second stop surface 16 equally abutting on the second limit surface 19.
  • the position of the connecting profile 7a with respect to each of the rails 1, 1' is therefore fixed with no rotation about the cylinder axes 15, 15' and practically no play in other directions being possible.
  • the side bars 2, 2' of the neighbouring rails 1, 1' are fixed in a relative position where their upper surfaces are coplanar, i.e., include an angle of 180°. Forces acting between the connecting profile 7a and the rail 1 or the rail 1' are distributed over rather large surfaces and mechanical strain remains modest. This is aided by the lateral face 8 of the side bar 2 abutting on the opposite lateral face of the side bar 2'.
  • the connecting profile 7a is very robust and the connection between the neighbouring rails 1, 1' can therefore withstand large forces and momenta.
  • the second connecting profile 7b is (s. Figs. 4, 4a ) similar to the first connecting profile 7a, comprising coupling rods 11, 11' which, however, are at a distance from each other, connected by a web 21.
  • the web 21 is joined to the coupling rod 11 along a strip which interrupts the concave circumferential surface 13 and to the coupling rod 11' in the same manner, the cross section of coupling rod 11' again being a mirror image of the cross section of coupling rod 11.
  • a sequence of oval openings 22 is spaced along the web 21 in the longitudinal direction which openings connect an upper surface of the same with a lower surface, allowing dirt to fall through which is thereby removed from the surface of the floor mat. Connecting profiles with webs of different breadths can, of course, be used, depending on preferences.
  • the stop surface angle ⁇ is 180°, that is, smaller than the limit surface angle ⁇ of 195°.
  • This allows a rotation of the coupling rod 10 with respect to the rail 1 by 15° between a first position ( Fig. 4 ) where the second stop surface 16 abuts on the second limit surface 19 of the rail 1, the said surfaces forming a first stop which defines a lower limit of 180° for the angle between the upper surface of the rail 1 and the web 21, and a second position ( Fig. 5 ) where the first stop surface 14 abuts on the first limit surface 18, the surfaces forming a stop which defines a lower limit for the angle between the upper surface of the rail 1 and the web 21.
  • the connecting profile 7b is therefore, with respect to each of the neighbouring rails 1, 1' it connects, rotatable about the respective cylinder axis 15; 15' by the difference between the limit surface angle ⁇ and the stop surface angle ⁇ without allowing other relative motion apart from very limited play. If both rails 1, 1' assume the first position with respect to the connecting profile 7b the angle between the upper surfaces of the neighbouring rails 1, 1' equals an upper limit angle of 180°. Larger angles are not possible. This position is normally assumed when the floor mat is in use. Due to this limitation of the angle between the upper surfaces of the neighbouring rails 1, 1' buckling of the floor mat is not possible.
  • the coupling slot 9 has a width sufficient to allow a corresponding motion of the web 21.
  • the lower limit angle ⁇ can be varied according to the specific needs by an appropriate choice of the inclination of the first stop surface.
  • a preferred range is 120° to 170°.
  • the upper limit angle can differ from 180°, in particular, can be slightly larger, or can remain undefined where buckling of the floor mat is not to be apprehended.
  • the lateral extension of the groove would still be rather small, in the example about 1.5 times the distance between the cylinder axis 15 and the concave circumferential surface 17, i.e., the radius of the latter, even where the second limit surface is parallel to the lateral face.
  • the lateral extension of the same could be even smaller.
  • the lateral extension of the side bars 2 can be kept small and the margin strips 3 correspondingly narrow as is usually desired.
  • a fixing clip 12a for use with the first connecting profile 7a is shown in Fig. 6 .
  • it consists of an elastic wire, e.g., a steel wire, and has a first straight leg 23 and a second straight leg 24 which enclose an acute angle and are connected by an arcuate section 25.
  • the distance between the ends of the legs 23, 24 is somewhat larger than the distance between the cylinder axes 15, 15'.
  • the ends of the legs 23, 24 are accommodated in the flutes 20 provided in the bottom surfaces of the coupling grooves 10 such that their positions are essentially fixed.
  • the arcuate section 25 may also extend into the flutes 20 whereby rotation of the fixing clip 12a is reliably prevented.
  • a fixing clip 12b for use with the second connecting profile 7b is shown in Fig. 7 .
  • a floor mat consisting of rails, connecting profiles and fixing clips as described can easily be assembled on the spot with no special tools being required by longitudinally inserting the coupling rods of connecting profiles into the coupling grooves of neighbouring rails and fixing them against longitudinal displacement by inserting fixing clips. Disassembling the floor mat is just as easy and does not require special tools either.
