Description

DESCRIPTION

Toilet lid fittings

The present invention relates to toilet lid fittings and their connection to the toilet bowl according to the preamble of Claim 1, hereinafter abbreviated to: toilet fittings. Many such toilet lids and fittings are known in the art. A common feature of relevant inventions is that a basic element is fastened in the two holes or openings, which at least the toilet bowls used in Europe and the USA have on the rear edge, typically with through bolts, to which a hinge joint or, generally, a swivel element is then fastened, supporting indirectly or directly the so-called toilet seat and/or one or two toilet lids, i.e., toilet fittings. The problem that arises here does not reside in the mechanical structural requirements that need to be solved, but rather in cleaning, particularly of the area in which the toilet bowl and the toilet fittings abut in the hinge region. This problem occurs in an accentuated manner where the indeterminate public uses the toilet, such as in restaurants, hospitals and naturally in public toilet facilities in particular. Toilet facilities which suffer from this sanitation problem have therefore been publicised.

Such devices are known from DE 102009 043 851 (Dl), DE 10 2008 058 580 (D2), US2008/0271230 (D3), EP 1800 585 (D4), DE 20 2008 007658 (D5). DE 44 19 469 A1 discloses toilet lid fittings according to the preamble of Claim 1. A common feature of all these devices disclosed in the publications mentioned is that the toilet lid or lids can be removed in just a few easy steps for cleaning the bowl and/or the lid. In the case of Dl, a separate cleaning system is provided, which can make such a system attractive for hospitals or public toilets, but because of the size of the system, and presumably its price, would not be considered suitable for a private household. The devices according to D2 - D5 still suffer from the disadvantage that, after the toilet lid fittings are removed, one or two elements remain connected to the bowl and are bolted to it, so that gaps or corners remain that are awkward or difficult to clean and that are questionable from the sanitary standpoint.

The object of the present invention is to provide a device that eliminates this situation.

The solution of the stated object is reflected in the characterising part of Claim 1 with respect to its basic elements, and in the further claims with respect to further advantageous embodiments.

The rear horizontal fixing strip of the toilet bowl supports two through-holes for receiving fixing elements. The through-holes are in most cases made relatively large so that toilet fittings from different manufacturers with different standards can be received. However, a first blocking element, each comprising an insert element of lid fittings in the through-holes in a positive locking manner but with play, is inserted in each of these through-holes. The insert dimensions are dimensioned so that they fit into the through-holes with play and have an edge bead at their upper boundary, serving as a stop when the insert elements are inserted so that the inserting process is divided clearly into two phases: a first phase during which the insert elements, with blocking elements mounted on them, can be inserted into the through-holes as far as the stop of the edge beads on the toilet bowl, and a second phase during which pressure can be exerted on the rear edge of the lid fittings, with the pressure pushing a substantially spherical end of each end of the insert elements through the two blocking elements. The blocking elements are produced from an elastomer which is compressible to a suitable extent and supports a plastic or metal protective cap where the lid fittings are mounted.

The inventive concept is explained in greater detail by means of the drawings.

Fig. la shows a first embodiment of toilet fittings in a position in which, although they are inserted in a toilet bowl 1, they are not yet locked. Only the rear horizontal fixing strip of the ceramic toilet bowl 1 is shown. It supports two through-holes 2 for receiving fixing elements, hitherto mostly bolts. In most cases, through-holes 2 are made relatively large so that toilet fittings from different manufacturers with different standards can be received. A first blocking element 3, each comprising an insert element 4 of lid fittings in the through-holes in a positive locking manner but with play, is inserted in each of these through-holes 2. Insert elements 4 are dimensioned so that they fit into through-holes 2 with play and have an edge bead 6 at their upper boundary, serving as a stop when insert elements 4 are inserted so that the inserting process is clearly divided into two phases: a first phase during which insert elements 4, with blocking elements 3 mounted on them, can be inserted into through-holes 2 as far as the stop of edge bead 6 on the toilet bowl, and a second phase during which pressure can be exerted on the rear edge of lid fittings 6, with the pressure pushing a substantially spherical end 7 of each end of insert elements 5 through the two blocking elements . Blocking elements 3 are produced from an elastomer which is compressible to a suitable extent, and supports a protective cap 6a f plastic or metal where lid fittings 5 are mounted as shown in Fig. lb. The assembly of elements 3, 4, 5, 6, 6a, 7 is delivered to the user, preferably fully mounted. Otherwise he must push insert elements 4 inversely through blocking elements 3, then screw them tightly in lid fittings 5.

Fig. lb shows the end of the second phase in which the lower ends of blocking elements 3 are widened by the substantially spherical ends of insert elements 5, thereby blocking lid fittings 5. If these are to be separated from the toilet bowl for cleaning purposes, the insert phase is reversed by pulling on lid fittings 5. No part of the inventive toilet lid remains on the toilet bowl and the - connected - parts of the toilet fittings can be supplied to cleaning.

Fig. 2a shows a second embodiment which embodies the same basic concepts as the first embodiment, but where the means for achieving the object varies. . A second insert element 11 each, with pre-assembled second blocking elements 12, is inserted into through-holes 2. These second blocking elements 2 each have a cylindrical through-hole in which the second insert element is able to move with play. Spherical end 13 of the second insert element is of a slightly larger construction than in the first embodiment according to Fig. 1 a, b, and in the insert position, it is located in an upper spherical detent (6b) in second blocking element 12. Behind toilet bowl 1, the second insert element 11 has a pivot axis 10 running transverse to it, with an eccentric element 8 and a lever 9 fixedly connected to it. The latter elements are arranged behind the toilet bowl.

Fig. 2b shows the apparatus according to Fig. 2a in the locked condition. Levers 9 are pivoted against each other, as indicated by the arrows. Levers 9 are therefore aligned colinear and can be locked against each other by means of a sleeve 9a, arranged on one of levers 9. Because of the simultaneous rotation of eccentric elements 8, the second insert elements 11 are slightly raised and spherical ends 13 push apart lower ends 13 of blocking elements 12, which project downwards through through-holes 2 into detents 6, thus locking the entire apparatus.

Fig. 3a, b shows a third embodiment of the inventive concept. Fig. 3a in turn shows only the device in use, the second drawing Fig. 3b shows the locked apparatus.

Whilst eccentric elements 8, lever 9, sleeve 9a, pivot axis 10 from the embodiment according to Fig. 2a, b are included without modification, the variant of a third blocking element 14 is present here. This element consists of an outer sleeve 14a and an inner sleeve 14b, which can be axially bolted together so that their total height can be adapted to the thickness of the rear edge of toilet bowl 1. Furthermore, this third blocking element 14, which is movable in through-hole with play, does not support an edge bead 6, but here protective cap 6a covers an elastomer washer and outer sleeve 14a of the third blocking element. At the lower end, the third variant of an insert element 15 supports a washer 16, which is bolted to a - vertically movable - third insert element 15. The diameter of washer 16 is dimensioned so that it fits with play through through-hole 15 in toilet bowl 1. .

If lid fittings are now to be interlocked with toilet bowl 1, levers 9 are shifted inwards, levers 9 are shifted inwards and are locked with sleeve 9a, as shown in the embodiment according to Fig. 2a, b. This raises washer 16 and a short elastomer tube 17 is deformed so that the third insert element 15 is locked. A variant of this is shown in Fig. 4. Only the two sleeves 14a, b of the third blocking element 14 are affected thereby. Outer sleeve 14c bears some, three for example, horizontal slots 18 that are parallel to each other, corresponding to cams 19 on an inner sleeve 14d. The height of third blocking element 14 may therefore be adjusted in steps. If they are not locked, lid fittings 5 can still be separated by simply lifting it off toilet bowl 1, so that both parts - namely toilet bowl 1 and lid fittings 5, are fully separated, without parts remaining on toilet bowl 1, and can be supplied for suitable cleaning. A common feature of all the lid fittings 5 described here is that they can be separated without parts remaining on toilet bowl 1 after releasing actuation of the interlocking device by lifting lid fittings 5 from toilet bowl 1, without parts remaining, so that they can be individually supplied to a cleaning process.
