[0001] The object of this invention is a self-regulating heel for the base of furnishing
               units.
 
            [0002] The invention is applied preferably, but not necessarily exclusively, in the home
               and office furnishing sector to cover the space at the bottom of the furnishing unit.
 
            State of the Art
[0003] The technique currently used to maintain the base of furnishing units at a certain
               distance from the floor is by means of support feet, especially for practical reasons
               such as cleaning underneath the unit, or to avoid the base of the unit being damaged,
               for example by the infiltration of water between the unit itself and the floor.
 
            [0004] The space between the unit and the floor is generally due to the aforementioned support
               feet, usually only a few centimetres high, attached to the base of the unit. The support
               feet may also be regulated to establish a steady, level position of the unit.
 
            [0005] Since the support feet are not particularly attractive, and also to avoid dirt and
               dust accumulating underneath the unit, it is quite common to use a lath that clips
               on to the support feet of the unit to cover the space. It can then be easily removed
               for cleaning purposes, for example. This protective covering is generally known as
               a "heel".
 
            [0006] The heel also serves as a form of skirting board, such as those found at the base
               of walls, and helps to avoid wear and tear of the unit since it can be easily replaced
               if subjected to damage.
 
            Drawbacks of the current systems
[0007] The drawback of the clip-on lath type of heel is that, in spite of the support feet
               being adjustable in height to keep the base of the unit away from the floor, the distance
               between the base of the unit and the floor is not necessarily always even and there
               will inevitably be gaps between the base of the unit and the lath, and the lath and
               the floor (due to the lack of parallelism between the base of the unit and the floor).
 
            [0008] Another drawback is the high cost of this type of heel that clips on to the support
               feet or to the unit itself, and the fact that it is not always an easy system to use.
 
            The aim of the invention
[0009] The aim of the invention herein described is to overcome the aforementioned drawbacks,
               by introducing an extremely simple, quick-fitting and economical heel for the base
               of furnishing units, without complex and difficult systems that clip-on to the support
               feet or the furnishing unit, while at the same time eliminating the gaps between the
               floor and the base of the furnishing unit.
 
            Essence of the invention
[0010] The aforementioned problems are resolved as claimed by means of a new type of heel
               characterised by the fact that its height is elastically self-regulating.
 
            [0011] The self-regulation of the height is obtained by means of a heel made up of two parts
               that fit one over the other transversally along their height. Springs are positioned
               between the two parts in order to hold them apart at the required distance.
 
            [0012] In this way, by pressing the two parts together against the springs, it is easy to
               slip the heel into the space between the base of the furnishing unit and the floor,
               without resorting to complex, expensive methods to fasten it to the unit. When released,
               the two parts will immediately position themselves correctly, even in those spaces
               that are not perfectly parallel, without leaving any gaps.
 
            [0013] The fitting together of the two parts is obtained due to the fact that the upper
               part is basically an inverted "U" shape, and sits over the lower part, which is a
               rectangular shape. A series of leaf-springs are then placed between the two parts,
               but helicoidal springs can also be used.
 
            [0014] With the upper part of the heel having the aforementioned inverted "U" shape, the
               accumulation of dirt will be avoided.
 
            [0015] To sum up, through this simple and previously unknown solution, the problems associated
               with easy application and fastening, the elimination of gaps, the simplicity of substitution
               and, at the same time, low manufacturing Costs for a system that does not require
               means of fastening or hooking to the unit or support feet, are resolved.
 
            Description of a typical way of applying the system
[0016] These and other advantages, with the aid of the included drawings, will be outlined
               in the following description of a typical application of the system, although these
               particulars are not to be considered exhaustive but merely a typical example.
               
               
Figures 1, 2 and 3 are three-dimensional views of the three single components that,
                  when fitted together, form the new type of heel described in this invention.
               Figure 4 is a front-on view of the base of a furnishing unit with the new type of
                  heel covering the space between the base and the floor.
               Figure 5 is a sectional transversal schematic view showing the structure of the heel
                  and how it is installed beneath the unit, by simply pushing it against the support
                  feet attached to the unit without using any type of fastening technique, as with traditional
                  methods.
 
            [0017] In the figures, the unit, or the base of the unit, is indicated by (1), the adjustable
               feet by (11) and the floor is indicated by (P).
 
            [0018] The heel is indicated by (2) and is made up of a traditional rectangular lath (22),
               over which an inverted "U" shaped piece made of aluminium or plastic (21) is positioned,
               with springs (23) to hold the two parts at a certain distance from each other.
 
            [0019] The springs (23) may be either free, or fixed to one of the two parts.
 
            [0020] The springs may also be of a different type, for example helicoidal, with a cylindrical
               seat on the inside surface of the upper part (22), or even other forms of leaf-spring
               with only one leaf, for example, (231 or 232), instead of the indicated optimum solution
               with two leaf-springs and an intermediate part that can be glued or screwed to the
               inside of the heel.
 
            [0021] The central interconnecting part (233) is also an inverted "U" shape that fits over
               the top of the lower part of the heel (22). In this way, there is no need to use any
               fixing technique, further reducing the overall cost of this alternative solution.
 
            [0022] The interconnecting "U" part can obviously be positioned in various combinations
               of shapes and numbers without changing the essence of the invention.
 
            [0023] The shape and number of the springs, as stated, may vary without altering the essence
               of the invention.
