    Field of the Invention The present invention relates to modular floor units, in particular modular floor mats, such as for wiping footwear as used at building entrances.
    Background of the Invention Floor mat systems of the above type are well known from e.g. Fit T-slots provided in the wiping units. The wiping units are separated by the connecting elements for dropping dirt between them. The system may also have flexibility to roll up the wiping units so that the dirt collected underneath can be regularly removed and / or to facilitate transportation and handling thereof. This is achieved by making the connecting elements flexible, such as by making them from rubber or another elastic material.
    In both the above documents, the connecting elements are short parts compared to the length of the wiping units, while the T-slots form channels along the full length of the wiping units. To assemble the system, connecting elements are inserted at one end into the T-slots and pushed along them until they are in place. To prevent the connecting elements from moving, CH 692 442 proposes to make the ends of the connecting element that go into the T-slots slightly larger. However, this makes it more difficult to slide the connecting elements to their location along the units, especially for long wiping units, where connecting elements must be placed at regular intervals.
    Another solution is shown in US6434779B1. This document shows a mat comprising longitudinal rail elements assembled by connector elements of extruded polymeric material. The rail elements have leg parts while the connector elements have U-shaped socket parts that fit on the leg parts. Furthermore, anchor tabs are provided which are pushed laterally along the side walls of the U-parts after the assembly step, to secure the connecting parts and to prevent the rail elements from being moved longitudinally with respect to the connecting elements. The presence of the U-parts makes the design and production of the connecting elements complex. Furthermore, the additional step of attaching comprising the anchor tabs makes the assembly process complex.
    The product described in the document EP1149554 is another example of a foot mat comprising longitudinal mat profiles held together by connecting elements. The connecting elements are formed on a flat part comprising a middle part and two side parts. On each of the two side portions is a vertically upright fastening element that may be a flexible angular element configured to snap into corresponding vertical openings in the profiles. The middle part is provided with a separating element, the height of which corresponds to the height of the profiles. These connecting elements are technically quite complex. This is partly due to the fact that the connecting elements not only serve to connect and hold the profiles relative to each other, but also to support the profiles. In other words, the profiles rest on the two flat side parts, which therefore also have to perform an anti-slip and damping function with respect to the supporting surface on which the mat rests. This also means that the connecting elements must run along a considerable part of the length of the profiles. The presence of the separating element makes the connecting elements freely visible, which can reduce the aesthetic aspect of the mat. The force transfer between adjacent profiles is further less than optimal because the part that bridges the gap between two profiles is on one side of the height of the profiles, so that a force separating two profiles can result in a tilting movement of the profiles as well as in a high force exerted on the vertically upright fastening elements placed in the vertical openings.
    Characteristic Elements of the Invention It is an object of the present invention to provide an alternative modular system of the above type which overcomes the disadvantages of the prior art systems.
    The present invention generally relates to a modular floor unit such as a foot-wiping mat comprising a plurality of elongated floor unit elements which are separated and interconnected by connecting elements, wherein the floor unit elements are provided with lateral grooves, and wherein the connecting elements comprise a central part for bridging the gap between two adjacent floor unit elements and a pair of laterally placed resilient members inserted into said grooves. When the floor unit is placed on a flat surface, the central part is located between said floor surface and the upper surface of the floor unit. Preferably, the grooves have an outer edge and an inner edge, the outer edge being at a lower level than an inner edge when the profiles are placed on a surface, with grooves facing upwards.
    According to an aspect of the invention there is therefore a modular floor unit according to the appended claims. The invention therefore relates in the first place to a modular floor unit comprising a plurality of elongated mutually parallel floor unit elements which are spaced apart and interconnected by connecting elements, wherein each pair of adjacent elements when placed on a flat surface , are located between a first surface defined by said flat surface and a second surface defined by the upper surface of said adjacent elements, the floor unit elements are provided with lateral grooves, which are provided with a protrusion on the inner surface surface thereof, the connecting elements comprise a central part for bridging the gap between two adjacent floor unit elements and a pair of laterally placed resilient parts inserted into said grooves, said resilient parts being formed as plotted also parts of a web material, wherein said pleated parts comprise a first leg part which is fixed to the central part of the connecting element, a bent part and a second leg part, the second leg part being secured behind the protrusion provided in the grooves, the central part being located between said first and second plane.
    According to an embodiment, the grooves have an outer edge and an inner edge, the outer edge being at a lower level than the inner edge when the profiles are placed on a support surface with the opening of the grooves oriented away from the support surface. wherein said levels are measured relative to said support surface, and the central portion is located between the levels of the inner and outer edges. This means that the central part is located between the levels at which the inner and outer edges of the grooves are located with respect to the support surface, when the floor unit is placed on the support surface with the opening of the grooves facing or away from the support surface .
    As mentioned, the second leg portion is secured behind the protrusion provided in the grooves. In other words, said protrusion prevents the end of the second leg portion from coming out of the groove in a direction perpendicular to the groove.
    In a modular floor unit according to the invention, the resilient parts and the said grooves are provided such that the resilient parts of a single connecting element are placed in the grooves of two adjacent mate units, and this placement can be obtained by pushing the connecting element in a direction perpendicular to the grooves until the pleated parts are inserted and fixed in said grooves.
    When they are secured in the grooves, the pleated parts of the connecting elements are in a compressed state: the leg parts are compressed laterally so that they exert an elastic counterforce on the side walls of the grooves.
    According to an embodiment, the central part and the resilient parts are formed from one piece of said web material.
    According to an embodiment, the first leg part is substantially perpendicular to the central part.
    At least one of the connecting parts may further comprise a longitudinal rib placed perpendicular to the central part of said connecting element. A spacer strip can further be placed on said rib, for maintaining a fixed distance between two floor unit elements when the floor unit is rolled up.
    In a modular floor unit according to the invention, at least the pleated parts of the connecting elements can be formed from a polymeric material. This is preferably a rigid or semi-rigid material such as polyoxy methylene.
    In a floor unit according to preferred embodiments of the invention, the pleated parts exert an elastic force on the inside of the grooves that is sufficient to stop any substantial longitudinal movement of the connecting elements relative to the grooves.
    According to the preferred embodiment, a plurality of connecting elements are mounted between the same pair of floor unit elements. The length of the connecting elements is preferably between 1 cm and 5 cm.
    According to an embodiment, the floor unit is a modular foot wipe mat, the floor unit elements comprising means for receiving and holding strips of mat material.
    The invention relates in the second place to a method for assembling a floor unit according to the invention, comprising the following steps: • providing at least two floor unit elements, • attaching the connecting elements to said floor unit elements by inserting the pleated parts of said connecting elements into the grooves of the floor unit elements in a direction perpendicular to the said grooves, the pleated parts being compressed by the insertion process, • securing the connecting elements by pushing the pleated parts beyond the protrusion provided in the grooves so that the pleated parts snap into place against the inside of the grooves and are thus secured in said grooves.
    According to an embodiment of the method, the first leg part of the pleated parts of the connecting elements is substantially perpendicular to the central part, and wherein the method comprises the following steps of placing said floor unit elements on a flat horizontal surface, with the inside of the grooves facing upwards, • gripping the connecting elements and moving them in a direction perpendicular to the flat surface, towards the floor unit elements, the folded parts being inserted into the grooves, so that both folded parts (21) of a connecting element are inserted simultaneously into two grooves of two adjacent floor unit elements; According to another embodiment of the method according to the invention, the first leg part of the pleated parts of the connecting elements is substantially perpendicular to the central part, and wherein the method comprises the following steps of placing said floor unit elements on a convex surface, with the inside of the grooves facing away from said surface, and two adjacent grooves of two adjacent floor unit elements facing away from each other due to the convex shape of the surface, • gripping the connecting elements and moving them in one direction perpendicular to the convex surface, to the floor unit elements, the pleated parts being inserted into the grooves, so that both pleated parts of a connecting element are inserted simultaneously into two grooves of two adjacent floor unit elements.

    Detailed description of the invention Figure 1 represents an example of an embodiment of a modular floor mat 10 according to the invention. The invention is mainly applicable to foot-wiping mats, but could also be applied to floor units with other functionalities, e.g. sound damping, floor lighting, etc.
    The mat 10 is formed by a number of mat elements 11, which are separated and mutually connected by connecting elements 12. Mat elements 11 are placed side by side and preferably parallel to each other, the connecting elements 12 being the openings between two adjacent mat elements 11. Mat elements 11 are preferably elongated, which means that their length is substantially greater than the dimensions along the two other directions in the space.
    The mat elements 11 are preferably provided in the form of elongated profiles, preferably made from an extruded material, such as aluminum or an aluminum alloy. The upper side of the profiles preferably comprises a centrally directed upwardly open channel 13 for receiving a mat strip or other wiping means (not shown). The sides of the profiles 11 comprise a groove 14 which runs along at least a part of the length of the units, preferably along the full length. The grooves are formed such that they interact with the connecting elements 12 in a manner described below. The width of the profiles 11 is preferably the same for the majority of the profiles within one unit of measure, possibly with narrower profiles positioned at the edges of the unit, such as profile 11 'shown in Figure 1, that a narrower brush element or a scraper might contain. Extra grooves 15 are formed on the underside of the profiles, for receiving rubber strips which can be mounted in said grooves 15 for damping the contact of the mat with the ground and / or for providing an anti-slip function.
    The connecting elements 12 are preferably formed from a synthetic composite material with a relatively high strength and rigidity such as polyoxyethylene (POM). As can best be seen on the front and top views of Figure 2, the connecting elements run a certain length L along the length of the mat elements 11. Preferably more than one connecting element 12 is placed between two adjacent mat profiles 11, the number of connecting elements 12 depends on the size of the mat. Each connecting element 12 comprises a central horizontal part 20 that bridges the gap between two adjacent profiles 11, and a pair of resilient parts 21, one on each side of the central part 20, the resilient parts 21 being formed of pleated web material, ie a plane sheet-like material formed in the form of a fold. The central portion 20 and the pleated portions 21 are preferably formed from a single piece of web material, as is the case in the embodiment in Figure 2. The pleated portions 21 are secured behind protrusions 35 provided on the inner surface of the lateral grooves 14 of the mate units.
    Figure 2 shows a side view of the modular floor mat according to the invention, placed on a flat surface 100. Each pair of adjacent mat elements 11 runs between a first surface 100 corresponding to the flat surface and a second surface 200 corresponding to the upper surface of the adjacent mat elements 11. As can be seen in the figure, the central part 20 of each connecting element 12 is located between the first and second surface 100/200. The central portion 20 is preferably positioned centrally between the two faces, wherein "central" means, for example, between 40% and 60% of the distance between the faces 100 and 200, starting from one of the said faces. The position of the second face 200 is preferably determined when there are no brushes or fibers present on the profiles. If not all mat elements are identical, the second surface 200 is determined by the upper surface of the highest mat element.
    The intermediate position of the horizontal part 20 means that this horizontal part 20 does not come into direct contact with the supporting surface 100, and also that it is not flush with the upper surface of the mat elements 11. The connecting element 12 used in the invention is used, has no supporting function of the mat elements 11 and also does not provide damping and / or anti-slip functions for these mat elements 11. These functions are performed by the mat elements 11 themselves, and can for instance be realized by providing damping and / or anti-slip elements in the grooves 15 on the opposite side of the grooves 14.
    In contrast to the existing systems, the connecting elements 12 in a floor unit according to the invention can thus be made more compact in the longitudinal direction of the mat elements 11, leaving more space between 2 connecting elements 12 mounted between a certain pair of mat elements 11 so that dirt and water can be removed more easily. The length of the connecting elements 12 is preferably small compared to the length of the mat elements 11. The length of the connecting elements 12 is preferably between 1 and 5 cm, more preferably between 1.5 and 4 cm, even more preferably between 2 and 3 cm. The connecting elements 12 are also less visible since they are located between the upper and lower levels of the mat elements 11, which improves the aesthetic aspect of the floor unit. The design of the connecting elements 12 is also an improvement over the existing systems in terms of the forces acting between the profiles 11 and the connecting elements 12. As shown in the figures, the central position (in the direction between planes 100) and 200) of the central part 20 of the connecting elements 12 and the fact that the connecting elements 12 are more compact, a more effective force transfer between adjacent profiles, which leads to a stronger and more reliable product.
    In the preferred embodiment shown in the figures, the position of the central portion 20 is further defined with respect to a preferred shape of the grooves 14, as will be explained below. With reference to Figures 2 and 4, when the mat elements 11 are placed with the mat side facing down on a support surface 100, so that the opening of the grooves 14 is directed away from the support surface, these grooves 14 have a lower edge 30 and an upper edge 31. The lower edge 30 is further outward laterally relative to the central vertical plane 32 of the mat element 11 than the upper edge 31. In other words, the lower edge 30 can be described as the "outer edge" of the groove 14, while the upper edge 31 is the "inner edge" of the groove 14, the terms "inner" and "outer" being used with respect to the central vertical plane 32 of the mat member 11. At the lower edge 30, the groove 14 is a vertically oriented edge portion 33 through which a holder 36 is formed for receiving the resilient part 21 of the connecting element, said holder being 36 formed between the edge portion 33 and the side wall 34 of the groove 14. On the upper edge 31, the side wall 34 of the mating unit is provided with a protrusion 35, ie a part protruding away from the side wall 34 over a certain distance, preferably oriented substantially perpendicular to said side wall 34. The protrusion 35 extends along at least a portion of the longitudinal direction of the groove 14.
    As shown in Figures 2 and 4, the central horizontal portion 20 of the connecting element 12 is located between the levels at which the lower and upper edges 30/31 of the grooves are located with respect to the supporting surface 100. This is so regardless whether the mat lies upside-down on the surface 100 (as in Figure 4, position for assembling the mat, see below), or with the mat receiving parts 13 facing up (as in Figure 2, normal position of use). This specific shape of the grooves 14 facilitates the assembly of the modular mat in a single movement with the central part 20 of the connecting elements 12 automatically secured in its intermediate position between the surfaces 100 and 200. The connecting elements can be pushed down with the resilient pleated side portions snapped into the grooves, as will be explained in further detail below.
    A centrally located vertical strip 22 may be provided, the function of which relates to the method for assembling profiles into a mat, as described further below in this text.
    As shown in detail in Figure 3, with the connecting element 12 held upside down, the pleated portions 21 have the following components, starting from the central horizontal portion 20: a downwardly oriented first leg portion 23 that is substantially perpendicular to the central portion 20, a curved portion 24 and an upwardly oriented second leg portion 25. In the non-assembled state shown in Fig. 3a, the upwardly oriented leg portion 25 is preferably tilted outward relative to the vertical plane of symmetry of the connecting element 12 through an angle α that is greater than 0 ° and smaller than 90 °. The dimensions and material characteristic of the web material from which the pleated parts 21 are made are chosen such that the pleated parts 21 exhibit a degree of resilience: when they are compressed by a lateral compression force F, it exercises the leg portion 25 directed upwards an elastic counterforce. As we can see again in Figure 2, we notice that the second leg part 25 is secured behind a protrusion 35 provided in the grooves 14. The resilience of the pleated parts 21, together with the protrusion 35 provided in the grooves 14 , ensures a quick and easy assembly of the unit units, as illustrated in relation to Figure 4.
    The mat is assembled by placing the mat profiles 11 facing down on a flat surface 100 as shown in Figure 4a, at a predetermined distance from each other according to the dimensions of the connecting element 12. The connecting elements 12, preferably gripped by the central strip 22 are lowered so that the pleated portions 21 are inserted into the retainers 36 formed by the edge portion 33 and the side wall 34 of the grooves 14. The shape and size of the grooves 14 ensures that the legs 23/25 of the pleated parts 21 are compressed by the insertion process, until the legs 25 are pushed beyond the protrusions 35, to subsequently snap into place and thus be secured behind said protrusions. This assembly of the mats can be done either manually or in an automated process.
    According to a specific embodiment of the assembly method, the profiles are placed on a convex surface 101 before assembly, as illustrated in Figure 7. Two adjacent grooves 14 of adjacent mat elements 11 are thereby slightly oriented away from each other. This facilitates the insertion of the pleated parts 21 into the grooves 14 so that snapping of the legs 25 behind the protrusion 35 becomes easier, i.e. requires a lower force to push the connecting elements 12 into place.
    The spring force of the pleated parts 21 secures the connecting elements 12 in such a way that the mat profiles 11 are kept at a fixed distance from each other. According to a preferred embodiment, the elastic force exerted by the leg parts 23/25 of the compressed pleated parts 21 on the side walls of the grooves 14 is such that the connecting parts 12, once they are fixed in the grooves, are longitudinal displacement of the profiles 11 with respect to the connecting parts 12 and vice versa. No additional manipulation is required to obtain this longitudinal attachment.
    The connecting parts 12 are preferably sufficiently flexible to allow rolling up of the assembled mat. It is possible to roll up the mat with either the top or the bottom side of the mat facing outwards.
    According to a preferred embodiment, a flat strip 40 is provided at the outer end of the positioning strip 22, preferably perpendicular to said positioning strip, as illustrated in Figure 5. This flat strip is provided for retaining from a fixed distance between two mat profiles 11 when the assembly is rolled up with the wiping elements (fixed in the spaces 13) facing outwards.
    The connecting elements 12 are preferably disposable elements that can be broken off by manual manipulation of the profiles 11. The disassembly of the measuring unit is in that case done by breaking off the connecting elements.
    The invention is not limited to the geometries illustrated in the figures. Connecting elements 12 may have a central portion formed of a material other than the pleated portions 21. The pleated portions may be oriented at a different angle to the central portion than the substantially perpendicular orientation of said pleated portions illustrated on the figures. However, the perpendicular orientation is preferable since it allows for easy assembly of the floor unit. The shape of the grooves 14 may differ from the example shown in the figures.
    The protrusion 35 can be located on any of the two side walls of the groove 14. When it is placed on the opposite side wall compared to the embodiments shown in the figures, the pleated parts 21 must also be turned over: the leg part with the free end 25 will then be placed closer to the center line of the connecting element than the fixed leg part 23. This embodiment is illustrated in Figure 6.
    Although the invention has been illustrated and described in detail on the figures and previous description, such illustration and description should be considered as illustrative or exemplary and not restrictive. Other variations on the described embodiments will be apparent and can be performed by those skilled in the art in the practice of the invention according to the claims, based on a study of the figures, the description and the appended claims. In the claims, the word "comprising" does not exclude other elements or steps and the indefinite article "does not exclude a plural." The mere fact that certain measures are mentioned in mutually different dependent claims does not indicate that a combination of those measures cannot be used. Any reference sign in the claims should not be regarded as a limitation of the range.
