fig1 shows a plan view from the front of a support element 10 in accordance with the invention with a circular base surface 20 . a spigot - shaped element 12 which projects out of the plane of the drawing and has a substantially square cross - section with slightly arched outer sides is seated at the center of the circular base surface 20 of the support element 10 . a latch element 14 made as a cylindrical pin can be seen at the side of the spigot - shaped element 12 at the bottom in fig1 and 2 and projects out of this element . as can be seen in fig2 , the latch element 14 is held or fixed in the spigot - shaped element 12 by means of a plastic sleeve and is supported at a spring centering location 15 in the interior region of the spigot - shaped element 12 by a spring 16 , with the spring 16 being seated in a bore 17 of the latch element 14 and extending from this bore 17 up to and approximately into the center of the spigot - shaped element 12 . when the spring is compressed , the latch element 14 is countersunk in the spigot - shaped element 12 until it abuts an abutment surface 13 provided for this purpose with the annular surface bounding the end of the bore 17 . in the position countersunk up to the abutment surface 13 , it no longer only projects from the spigot - shaped element 12 , but it projects from the spigot - shaped element 12 when the spring 16 is relaxed and can thus latch into a corresponding cut - out in a tubular element of a functional element . in fig1 , two guide webs 18 are furthermore shown which extend perpendicular to the plane of the drawing at oppositely disposed sides of the spigot - shaped element 12 . these guide webs 18 converge toward the front in the direction of a functional element to be pushed on so that the pushing on of the functional element is facilitated which has cut - outs corresponding to the guide webs 18 in its tubular element . when the functional element is coupled to the support element 10 , the guide webs 18 form an additional security against rotation . in fig2 , in addition , two of four bores 22 are visible which are provided in circular form in the rear side of the support element 10 . the bores 22 serve for the screwing of the support element 10 directly to a wall or to a base element as will be explained later . fig3 a to 3c show different views of another embodiment of a support element 10 in accordance with the invention . in fig3 a , the support element 10 is shown in a perspective manner and a circular base surface 20 can be seen on which a cylindrical body 21 is seated at whose center the spigot - shaped element 12 is in turn located . the spigot - shaped element 12 also has a substantially square cross - section with slightly arched outer sides , with two guide webs 18 being disposed at the outer side , which converge in the direction of a functional element and of which , however , only one can be see in the figures . a quadrangular opening 24 is applied at the surface at the center of the spigot - shaped element 12 . at the outer side of the spigot - shaped element 12 adjacent to the guide web 18 , the latch element 14 can be seen in fig3 c which projects out of the spigot - shaped element 12 at the side ( downwardly with a mounted support element 10 ) and has a cylindrical shape with a rounded end face . the lower side of the support element 10 is provided with a star - shaped toothed arrangement 26 which is shown more precisely again in a plan view in fig3 b . this toothed arrangement 26 can , as shown in fig5 , cooperate with a corresponding toothed arrangement 27 in a cut - out 28 of a base element 30 whose shape corresponds to the shape of the base surface 20 of the support element 10 when the support element 10 is inserted into a cut - out 28 of this type and can thus form a security against rotation . in fig4 , the support element 10 from fig3 a to 3c is now inserted into a circular base element 30 or is made in one piece with the base element 30 . the base element 30 can be screwed firmly to a wall and has a circular base surface at whose center a likewise circular cut - out 28 for the support element 10 is provided whose diameter corresponds to the diameter of the base surface 20 of the support element 10 . the latch element 14 is not visible in fig4 since it lies at the lower side of the spigot - shaped element 12 ; however , the guide web 18 can be seen on the left - hand side of the spigot - shaped element 12 . in addition , a functional element 40 is shown in fig4 which can be pushed onto the support element 10 . the functional element 40 is a double hook which has a tubular element 42 with which it is mounted onto the support element 10 . the inner cross - section of the tubular element 42 corresponds to the outer cross - section of the spigot - shaped element 12 , with two cut - outs also being provided which are not visible in the figure and which correspond to the guide webs 18 . in addition , a cut - out ( again not visible in the figure ) for the latch element 14 is formed at the lower side of the tubular element 42 . to push on the functional element 40 , the latch element 14 is depressed against its bias transversely to the direction of the longitudinal axis of the spigot - shaped element and then latches into the recess in the tubular element 42 . in the latched state , the support element 10 is firmly coupled to the functional element 40 so that the functional element 40 is secured against rotation and against being pulled out . the support element 10 is completely invisible in this coupled state and the tubular element 42 of the functional element 40 is seated in a shaped matched manner in the cut - out 28 of the base element 30 . fig5 likewise shows the support element 10 of fig3 a to c and of fig4 , but this time with a different base element 30 . the base element 30 is an elongate shield which can be screwed to a wall and which has two cut - outs 28 for support elements 10 . the two circular cut - outs 28 are provided at the front side at the end regions of the shield 30 remote from one another and each have a toothed arrangement 27 which cooperates with the toothed arrangement 26 at the rear of the support element 10 . unused fastening points can , for example , be masked behind the shield 30 . the screw 32 serves for the screwing of the support element 10 in the cut - out 28 . instead of the double hook shown in fig4 , any desired other functional elements usable in the sanitary sector can be combined with the support element 10 in accordance with the invention . for example , paper holders , soap dishes , toothbrush holders , handles and hooks , cosmetic holders and similar are thus feasible so that a plurality of combination possibilities are created with different conceivable base elements .
the invention relates to a system of a support element and at least two functional elements which can be used in the sanitary sector , with the support element being able to be coupled to each of the functional elements via a system interface and the system interface having a spigot - shaped element — at the support element side — with an outwardly biased latch element projecting out of said spigot - shaped element transversely to its longitudinal axis and the functional elements each having a tubular element corresponding to the spigot - shaped element and having a cut - out for the latch element .
