TOILET-LID FITTING
A lid fitting (5) for a toilet bowl (1) can be inserted into through-holes (2) in the rear periphery, each with a blocking element (3). Each of said blocking elements contains an insert element (4) of the lid fitting (5), in which case they are movable with vertical play in the insert element (4) and fit into the through-holes (2) with play. The blocking elements (3) each have two spherical notches (6b, c), in which a spherical lower end (7) of the insert element (4) can be accommodated in each case. The blocking elements (3) bear, at their upper boundary, a peripheral bead (6) with a protective cap (6a) made of metal or plastics material. The lid fitting (5) has two positions, that is to say an insertion position, in which the spherical lower end (7) can latch in the spherical notch (6b) of the first blocking element (3), and a second spherical notch (6c) in the vicinity of the end, it being possible for this notch to retain the blocking element (3) in the locking position. By virtue of the rear periphery of the lid fitting (5) being subjected to pressure, the lid fitting can be moved from the insertion position into the locking position and, by virtue of the lid fitting (5) being subjected to vertical pulling, the lid fitting can be released from the locking position and the lid fitting (5) can be raised up from the toilet bowl (1) and can undergo cleaning.
This application is a US national stage application filed under 35 U.S.C. §371 based upon International Patent Application PCT/CH2012/000155, filed 5 Jul. 2012, which claims the benefit of Switzerland application 1119/11, filed 5 Jul. 2011, the entire contents of which are hereby incorporated by reference as if fully set forth herein for all purposes.
The present invention relates to a toilet lid set and its connection with the toilet bowl, hereinafter abbreviated to toilet set. Many such toilet lids and sets are known. All related inventions share in common that the two holes or openings exhibited at the rear periphery of at least those toilet bowls used in Europe and the US have secured in them by way of continuous screws a base element, to which is then secured a hinged joint, or generally a swiveling element, which then directly or indirectly carries the so-called toilet seat and/or one or two toilet lids, i.e., a toilet set. The problem arising here does not involve the mechanical and structural requirements to be met, but rather has to do with cleaning, above all the zone where the toilet bowl and toilet set impact each other in the hinged region. This problem is encountered to an accentuated extent where the general public uses the toilet, as in restaurants, hospitals, and of course especially in public toilet facilities. This is why toilet facilities that embody particularly these hygiene problems were published.
Such devices are known from DE 10 2009 043 851 A1 (D1), DE 10 2008 058 580 A1 (D2), US 2008/0271230 A1 (D3), EP 1 800 585 A2 (D4), and DE 20 2008 007 658 U1 (D5).
All of the devices disclosed in the mentioned publications share in common that the toilet lid(s) can be removed with a few hand movements to clean the bowl and/or the lid. D1 provides a separate cleaning system that can make such a system attractive to hospitals or public toilets, but the size of the system and presumably its price would sooner rule it out for private households. Devices in D2-D5 still have the disadvantage that one or two elements remain connected with the bowl, being tightly bolted thereto, after the lid set has been removed, leaving narrow gaps or corners that are inefficient or difficult to clean, and dubious from a hygienic standpoint.
The object of the present invention is to provide a device that eliminates this circumstance.
The set objective is achieved as described in context with the invention herein below in terms of its basic elements, and with regard to other advantageous embodiments.
The rear horizontal fastening ledge of the toilet bowl has two through holes to hold fastening elements. The through holes are most often relatively large in size, so as to accommodate toilet sets from various manufacturers with different standards. A respective first blocking element is inserted into these through holes, each positively encompassing an insert element of a lid set, but with play. The insert elements are dimensioned in such a way as to fit into the through holes with play, and their upper boundary exhibits an edge bead, which serves as a stop while inserting the insert elements, so that the insertion process is clearly divided into two phases: In a first phase, the insert elements with blocking elements attached can be introduced into the through holes until the edge beads hit the toilet bowl, while in a second phase, pressure can be exerted on the rear edge of the lid set, wherein this pressure forces an essentially spherical end of each end of the insert elements through the two blocking elements. The blocking elements are made out of an elastomer, which can be compressed to a suitable extent, and bear a protective cap made out of plastic or metal where the lid set rests.
The inventive idea will be explained in more detail based on the drawings. Shown on:
A respective second insert element 11 with preassembled second blocking elements is inserted into the through holes 2. These second blocking elements 12 each exhibit a cylindrical through hole, in which the second insert element can move with play. The spherical end 13 of the second insert element is somewhat larger than in the first exemplary embodiment according to
While the eccentric elements 8, levers 9, bushing 9a, swiveling axis 10 from the exemplary embodiment according to
If the lid set 5 is now to be locked with the toilet bowl 1, the levers 9 are inwardly turned and secured with the bushing 9a, as described in the exemplary embodiment according to
The feature shared in common by all lid sets 5 described herein is that, after the locking device has been detachably actuated, they can be completely removed from the toilet bowl without parts remaining on the toilet bowl by lifting the lid set 5, so as to then each be separately sent to a cleaning process.

Claims
1. A lid set for a toilet with a toilet bowl whose rear edge exhibits two through holes, wherein
