Abstract

Un élément de liaison relie de manière rotative le siège et le couvercle (B)/(C) de toilettes et permet de les monter rapidement sur une cuvette (A) de toilettes ou autre installation recouverte d'un couvercle sans l'aide d'aucun outil et sans laisser des pièces de fixation sur la cuvette des toilettes ou autres cuves. Le siège/couvercle est fixé sur le bord de la cuvette par coincement d'éléments de serrage (4a+40) dans les orifices de vissage existants dans la cuvette, ou selon une deuxième variante, par pression atmosphérique exercée par des ventouses d'aspiration (15) auxquelles sont liés des éléments mécaniques de fixation similaires.A connecting element rotatably connects the toilet seat and cover (B)/(C) and allows them to be quickly mounted on a toilet bowl (A) or other covered installation without the aid of no tools and without leaving any fasteners on the toilet bowl or other bowls. The seat/lid is fixed to the edge of the bowl by wedging clamping elements (4a+40) in the existing screw holes in the bowl, or according to a second variant, by atmospheric pressure exerted by suction cups (15) to which similar mechanical fixing elements are linked.

Description

Connection element between the toilet seat cover and the toilet bowl

description

The invention relates to a quick connector in two

Different variants which rotatably connect the toilet seat ring and lid and securely clamped to the toilet bowl without the use of tools in the screw holes provided for this purpose, or in the second variant using a suction cup

With the help of atmospheric pressure by creating negative pressure adheres to the edge of the toilet bowl.

State of the art: None of the many applications and patents show that a toilet seat ring with or without a lid without leaving adapter parts, clamping devices or

the like, quickly (within 1, o seconds) from the toilet bowl

is removable. All include researched suggestions

Special seats to which only these adapted holding elements

are attached and need their counterpart, which to

Existing toilet bowls remain when changing the seat.

Also a threading tactic using 3 hands

(Finding holes on both sides and simultaneous threading as well

Holding the toilet seat / lid combination) is expected of the maintenance personnel, who are responsible for all previous inventions

their cumbersome deny large market entry. The

The invention has for its object all existing

To solve disadvantages advantageously and also to perfect them.

The object is achieved by each

existing toilet seat this quick connection against the

existing recording. -or guide mandrels are interchangeable. To

Remove the screw connections - usually two nuts with

The associated threaded rods turn into the toilet seat and cover

separately. To the threading problem of the very unwieldy

Parts; as stated in other patent documents; will turn off the fixed arbor (2e) which according to the invention has the special feature (FIGS. 1 + 2) that it can be inserted on one side diagonally to the imaginary axis through the toilet seat and cover bearing hole. This fixed mandrel (2e) still protrudes far enough out of the toilet seat bearing hole to move the cover in its pocket bore so that it can move on this spherical pin. The resilient mandrel (2a) is pushed into the bearing to bring it into the aligned position of the two holes in the toilet seat and cover. The mandrel automatically slides into the seat and cover storage. This assembly can be unique because the connecting element can remain on the seat and cover but does not have to. The connecting element has a

Base plate (1) from which two tie rods (4) with the associated clamping rubbers (4a) protrude. These two outstanding clamping elements are inserted into the screw holes in the toilet bowl. Any hole spacing differences of the toilet bowl screw-on holes are made equal by moving the eccentric lever (3) in the handle (3a) and the clamping elements (4a), which are connected via the driving pins (3c). The permanently connected seat / lid combination proves to be easy to use in order to insert this cutting connector into the toilet bowl screw holes within 0.5 seconds and to press the eccentric lever (3) downwards in order to achieve the volume displacement of the clamping rubbers (4a). that means to achieve an excellent jamming in the toilet bowl holes from the length reduction to the extension of the circumference. By moving the eccentric lever upwards by means of the handle (3a), the clamping rubbers (4a) give up their forced volume shift and change to the slim cylindrical shape, which enables the toilet seat / cover combinatiαn to be removed in an even shorter time, of course only that can Toilet seat can be equipped with these quick connectors.

Two sheets of drawings: Figure 1 + 2 The second variant according to FIG. 3 shows a quick connection with the same external dimensions, which uses the permanent air pressure to fasten the connecting element and thus the toilet seat / / cover combination. The base plate (10) of these quick connectors has in one piece a sucker receiving space (11) which has differently shaped 1 or 2 plate-shaped rubbers. - or soft plastic suction cups via driver bolts (13) in assigned holes through the receiving room ceiling. This sucker receiving space (11) is advantageously connected to the base plate (10) via 2 opposite connecting webs (11a) in order to eliminate unevenness and tolerances which toilet ceramic bowls are subject to. The protruding driver bolts (13) are coupled to the eccentric lever (14) via driver pins (14a). The circular lowering of the eccentric lever (14) causes the driver bolts (13) to be pulled out and thus the suction cups to arch, which represents an increase in volume. The associated generation of negative pressure within the

Suction surface allows the atmospheric external pressure to take effect, which allows the suction unit and the parts attached to it to adhere very well. Since the toilet bowls or other sanitary vessels have a glazed surface, permanent attachment is guaranteed. In order to eliminate lateral deflection forces and to ensure permanent positioning of the quick connector and the toilet seat / lid combination, these fixings can be achieved by means of the adjuster (17) rotatably mounted in the base plate (10) and the locking knobs (19). This adjustment work is necessary once before the adaptation to the intended toilet bowl because each toilet bowl type has tolerances and different dimensions. By means of receptacles (19) which are integrally eccentrically attached to the adjuster (17) and to which the appropriate locking pins are attached, the spacing of the two hops and thus the adaptation to any type of toilet bowl are possible by turning them. A coin reaches into the twisting slots (17a) so that the adjustment can be carried out without tools.

The set position of the adjuster (17) is secured by means of the latching lug (10a). The slot position (17a) provides information about the position of the locking knobs (19)
