Description

The present invention relates to a toilet set for a toilet (water closet).

Toilets regularly have a toilet body with a toilet bowl, which in many cases consists of ceramic. In the case of toilets intended for sitting, foldable parts are mounted on them in most cases, namely toilet seats or toilet lids or both. A toilet seat is used for the user to sit and a toilet lid for closing the toilet bowl, whereby a toilet seat is usually also covered. The foldable part is rotatably held on the toilet body via at least one mounting part.

In the following, the structural unit consisting of such an assembly part and the foldable part, i.e. a foldable toilet seat or a foldable toilet lid, is referred to as a toilet set, whereby, as just mentioned, a toilet lid does not necessarily have to be provided and therefore there is no question of a so-called lid set.

When the foldable part is folded up, it comes to a position that is generally somewhat beyond a vertical position, in which the foldable part lies against a wall on which or in front of which the toilet is mounted, or also against another toilet part. For example, if a toilet seat and a toilet lid are usually provided, the toilet seat can come to rest on or in the already opened toilet lid when it is folded up. In addition, there may be a system on a structure intended for a shower device in the rear (i.e. near the wall) part of the toilet if it is a shower toilet.

The JP 2014 066261 A is based on the preamble of claim 1 and shows a lid set and a toilet equipped with it, in which a rotary damper contains a locking mechanism. In this latching mechanism, two projections abut against each other during a folding movement, the projection being formed on a radially inner part on an elastic lever arm, can deflect inward when a certain torque is overcome and thus enable a further movement. Both end positions of the folding movement of a seat of the toilet are thus marked by a locking feeling for the user and the locking mechanism secures the seat in the folded-up position. A typical rotary damper also shows the JP 2015 194230 A ,

The invention has for its object to provide a toilet set and a toilet, which are improved with regard to the specific design of a rotary stop.

The problem is solved by a toilet set for mounting on a toilet body with a toilet bowl, which has a toilet set: a part which can be mounted on the toilet body and folded up and down and a mounting part which is used to mount the foldable part is designed on the toilet body and holds the foldable part rotatably, and a rotary damper for damping a folding movement of the foldable part, wherein the foldable part and the mounting part are connected via a pivot joint and wherein in a part surrounding a pivot axis of the pivot joint Toilet set a rotary stop is provided to limit the upward movement of the foldable part, which is formed between a part rotating with the foldable part and a fixed part with respect to the folding movement to the mounting part, characterized in that one of the two parts as the rotary damper Sleeve includes, as well as a toilet equipped with it.

A basic idea of the inventor was that the foldable part was in contact with another part of the toilet and in particular against a wall behind the toilet is common and if necessary also provides a suitable path limitation. However, it cannot be ruled out that a collision in the manufacture of this system leads to traces on the foldable part or the wall. This applies in particular to a toilet lid, in which such traces would be present on the upper side which is visible when the toilet is closed, and of course to a bathroom wall (perhaps with a sensitive surface) behind the toilet.

But even in the event of a collision between a fold-up fitting part and a shower facility housing in the rear area of a shower toilet or, in principle, also in the event of a collision between a toilet seat that has just been folded up and a toilet lid that has already been folded up, there may be visual defects or even minor damage come. In addition, the collision noise can be perceived as unpleasant and in any case does not necessarily convey a quality impression.

A rotary stop for the folding movement is therefore provided according to the invention, this rotary stop being provided in a part surrounding the axis of rotation of the folding movement. The rotary stop can ensure the position limitation for the fold-up movement and thus avoid an undesired collision.

The rotary stop is provided in a part of the toilet set that surrounds the axis of rotation. Such a part can e.g. B. concentric to the axis of rotation and substantially cylindrical, of which in the case of the mounting part a foot down or in the case of a toilet seat or toilet lid then the (with respect to the axis of rotation) distal regions extend more or less radially. This arrangement of the rotary stop allows a view-concealed, dirt-protected, easy-to-clean design that is uncritical in terms of injuries (pinching) and / or integrated in a practical manner with other parts, such as the swivel joint, as required and required. The rotary stop is therefore preferably designed to be concealed with regard to visibility, cleaning and / or access options.

It is designed so that it comes into effect before the system to be prevented is actually manufactured. For example. the toilet lid can be stopped by the rotary stop before it hits the wall, thus avoiding the impairments described above.

A preferred variant of the invention is directed to a toilet lid as a foldable part, that is to say to a toilet lid set with at least one lid (and preferably also a seat). Although in principle a turning stop is also useful and advantageous for a foldable seat, the collision described is generally more disadvantageous in the case of a toilet lid. It then affects a clearly visible surface (even when the toilet is closed) of the lid and also another part of the toilet, such as a shower facility housing, or the wall mentioned behind the toilet.

It is generally known to dampen the folding movement of a toilet seat or toilet lid referred to here. Suitable dampers can have an approximately cylindrical shape that is symmetrical with respect to the axis of rotation and can be installed in a similar way to the part of the foldable part or the mounting part surrounding the axis of rotation as the rotary stop. The folding movement can also be dampened by means of a rotary damper, so that the collision with the rotary stop takes place somewhat braked. In the same sense, rotary dampers have already been provided in the prior art in order to strike too hard. B. to avoid a toilet lid on a wall, but could not really prevent this, especially if e.g. B. Children handled a little impetuously with a toilet.

The rotary damper provided according to the invention can, however, also only be provided to dampen the lowering movement of the foldable part, at least in the vicinity of the rotary stop according to the invention (and possibly another rotary damper at another point).

In combination with a rotary damper, the invention provides a sleeve-like configuration of one of the two rotary bearing parts that belong to the rotary stop. For illustrative purposes, reference is made to the exemplary embodiment.

A further preferred embodiment provides that a part of the rotary stop, in particular the sleeve, is formed from a swivel part, that is to say from one of the parts which bring about the foldable mounting of the or a further foldable fitting part and run counter-rotating. Such swivel parts can then, for. B. by introducing suitable projections at the same time (ie in one piece) as a rotary stop. This ensures a particularly simple and economical implementation of the invention. In the exemplary embodiment, this applies specifically to a part of the swivel joint of a further foldable part, namely a seat with a rotary stop acting on a cover.

The rotary stop is preferably present several times, in particular twice. On the one hand, this can have the advantage of distributing the forces that occur. The accommodation of the rotary damper according to the invention relatively close to the axis of rotation inevitably results in relatively short lever arms, which is why this aspect can be relevant above all in the case of an inexpensive design in plastic (e.g. injection molding). In addition or alternatively, the advantage can be in the foreground to achieve a rotationally symmetrical design which, for example, during installation. B. with a two-fold symmetry, an exchange of "top" and "bottom" or of "left" and "right" allows.

The repetition of the rotary stop can be done along a revolution around the axis of rotation of the folding movement, so that, for. B. with a twofold symmetry, a rotation stop at the opposite position to the other (with respect to this rotation).

Another preferred embodiment of the invention relates to a snap mechanism. This means that a part of the rotary stop, i.e. one of the elements striking against each other, can elastically deflect in the event of excessive force and thus prevent the rotary stop from being destroyed. If e.g. B. in a family household, the turning stop is advantageous because a somewhat impetuous handling of toilet lids (or seats) by children is to be expected, this can also mean that they are zealous or ignorant. B. press the toilet lid beyond the end position defined by the rotary stop. In this case, the snap mechanism should prevent damage to the rotary stop and possibly the pivot bearing. Since in many cases there will only be a short movement distance to another limit, for example up to the wall, major damage to the toilet lid or toilet seat is not necessarily expected.

In this sense, one of the stop elements can be held elastically and evade as a result of this elastic mounting, for example by means of an elastic arm that runs approximately in the circumferential direction in a cut perpendicular to the axis of rotation and thereby covers a partial circumference (cf. exemplary embodiment). At a distal end of such an elastic arm (distal with respect to the transition of the arm to the part to which it belongs), e.g. B. a projection projecting radially outward or inward may be provided. Such an arm can e.g. B. can be realized cheaply in the aforementioned sleeve.

The snap-over function can be promoted in that one of the abutment surfaces of the rotary stop, which come into direct contact with one another, has a corresponding oblique orientation to the direction of this contact and can therefore apply a corresponding elastic force on the principle of the inclined plane.

Since the snap-action mechanism described is intended to function non-destructively, a snap-back possibility is preferably provided. With this, the original functional state can be restored after a snap, so z. B. stop elements are moved along again in order to get into the relative position causing the actual rotary stop. For this purpose, an inclined surface can also be provided on suitable stop surfaces, whereby this stop surface can have a significantly different inclination than the aforementioned one, so that smaller forces are sufficient for the snap-back. For an explanation, reference is made to the exemplary embodiment.

The invention also relates to a complete toilet with a foldable part and a holding device which rotates this part accordingly. If the toilet has a toilet set according to the previous explanation of the invention, the holding device corresponds to the mounting part. However, cases are also conceivable in which the holding device is made in one piece in the toilet body is realized and thus does not exist separately from the toilet body and which should also be included. The same applies analogously to toilets, in which such a holding device is part of another structure, such as a shower device structure, and is accordingly an integral part of an element which in turn primarily serves other purposes than holding the hinged toilet lid or seat.

The invention is explained in more detail below on the basis of a specific exemplary embodiment which is illustrated in more detail in the figures. It shows:

Fig. 4

shows in perspective and as an overview the toilet set from the Figures 1 to 3 ,

First, to illustrate the basic structure Fig. 4 referenced, which represents a toilet (lid) set according to the invention in perspective, with a lid 1 folded up and a seat 2 folded down. Both are held on a mounting part 3 on a toilet body, not shown, and can be folded relative to it.

Fig. 1 shows a detail perspective view from the left rear (in relation to the perspective of Fig. 1 and regarding a perspective with a view from in front of the toilet from diagonally left behind). In relation to Fig. 3 this concerns the left part of the illustration, with reference to Fig. 3 from the back left because in there Fig. 3 the perspective is directed horizontally from the front onto the wall.

The reference numeral 20 denotes an initially essentially cylindrical sleeve made of injection-molded plastic, the in Fig. 1 forward right and in Fig. 3 left-hand part has the shape of a pin 11. This sleeve 20 is according to Fig. 1 of a part 21 of the toilet seat 2, which part 21 in Fig. 1 is shown partially cut away, but actually runs around the sleeve 20 closed. This part 21 of the toilet seat 2 sits in Fig. 1 to the right behind in the toilet seat 2, what in Fig. 3 corresponds to a continuation upwards from the drawing level and in Fig. 2 to the right. The part 21 is freely rotatable relative to the sleeve 20 and together with this forms a pivot bearing for a folding movement of the toilet seat 2.

The cone extension 11 is in turn how Fig. 3 shows, form-fitting in one in Fig. 1 Hidden toilet lid 1 held and rotates accordingly with a folding movement of the toilet lid 1 with this. This is due to the one-piece design for the entire sleeve 20, the part opposite to the pin 11 (in Fig. 1 left rear) is rotatably received in the mounting part 3. This assembly part 3 can be seen in Fig. 3 in longitudinal section including its attachment via screw elements 4 in an underlying toilet body (the nuts on the external threads of the screw elements 4 are not shown). In the Figures 1-3 an upper cover of the mounting part 3, which is not essential for the function of this invention, is omitted, which explains the rib structure shown, which in the assembled and complete state according to FIG Fig. 4 is not visible, but has a reinforcing character.

This one in Fig. 1 axially rearmost part of the sleeve 20 lies in Fig. 3 (in the left part) on the right and is together with the mounting part 3 and part of the seat 2 in its vicinity Fig. 2 shown cut perpendicular to the axis of rotation. It can be seen that the sleeve has two arms 23 in this axially innermost section each has an approximately circular arc-shaped contour through a respective slot 24, one of which in Fig. 1 can be seen are decoupled from the rest of the sleeve. Since the sleeve is an injection molded part made of a polymer material that has a certain intrinsic elasticity, an elastic arm 23 is formed in each case through the slot 24.

At the respective distal end of each of the arms 23 there is a radially outwardly projecting projection 25, the radially outwardly facing outer surface of which extends approximately in the circumferential direction and the angled boundary surfaces thereof have different angles of attack with respect to the respective radial direction with respect to the axis of rotation. The surface pointing in the direction of the respective (remaining) arm is chamfered by a few degrees and the opposite surface pointing away from the lever by a significantly larger angle of approximately 30 °. Each arm 23, including its respective projection 25, covers an angular part of approximately 45 ° over the entire circumference.

On the other hand, the mounting part 3 has a substantially cylindrical inner lateral surface with two projections 26, which extend in the circumferential direction on its radially inward-facing boundary surface and on the two side surfaces angled to it (as in FIG Fig. 2 recognizable) again inclined by only a few degrees with respect to the radial direction. Fig. 2 illustrates that when the sleeve 23, i.e. the cover 1 coupled via the pin 11, rotates from the horizontal and closed position shown in the figures into the vertical, the projections 25 and 26 each approach one another by the projections 25 in Fig. 2 be turned counterclockwise. In the case of a stop position which is suitable and which is generally somewhat beyond the vertical position, contact is made so that the rotary stop formed by the projections 25 and 26 comes into effect.

If for some reason the cover 1 is moved beyond this position with a relatively large force, the small angles of attack mentioned in the lateral boundary surfaces of the projections 25 and 26 ensure that they are connected to one another are in contact (and parallel to each other), according to the principle of an inclined plane, for the respective projection 25 and with it the respective lever 23 to be pressed elastically inwards, so that the rotary stop is finally caused by an elastic deformation of the axially innermost part of the sleeve 20 can be overcome.

Conversely, as a result of the significantly more oblique design of the opposite side surface of the respective projection 25, the projections 25 of a return can "dip" under the projections 26 with less effort in order to return to the regular area.

Fig. 2 also shows within the sleeve 20 an axially inward and in Fig. 3 also visible pin 27 of the in Fig. 3 recognizable rotary damper 10. This is form-fitting in one Fig. 2 in section U-shaped and axially even further inside then held in the upper area of the closed mounting part 3. Thus, the rotary damper 10 is positively and in particular rotatably mounted in the mounting part 3, so that the loads resting on it are transferred to the mounting part 3 and ultimately its screw fastening parts 4. Since the rotary damper 10 has a damped rotary bearing in its function, it accordingly serves as a rotary bearing for the cover 1 (compared to the mounting part 3). Accordingly, the parts 23 to 26 described in connection with the rotary stop are not about a bearing function in the sense of a load bearing.

Fig. 1 also shows axially somewhat outside of the rotary stop described a resilient tongue 27 which, in contrast to the arms 23, extends in the axial direction. This has no essential significance for the invention and is therefore only briefly explained. As in Fig. 1 it is visibly thickened at its distal end and thus prevents the sleeve 20 from being pulled out to the front right out of the part 21 of the seat 2, as long as it is inserted by the rotary damper 10 ( Fig. 3 ) is prevented from elastically evading inwards. So it is a backup.

Fig. 3 shows, as already mentioned, the elements of the 1 and 2 in front view and in a section containing the axis of rotation horizontally (i.e. with respect to Fig. 4 in a perspective from bottom left to top right). Fig. 3 illustrates that and why the rotary damper 10 in Fig. 1 is not visible and how this blocks the tongue 27 just mentioned from the inside. It is pressed non-rotatably into the sleeve 20, that is to say connected non-positively to it. It can also be seen how the already mentioned pin 11 is held in a receptacle 12 of the cover 1 and how on the axially opposite side on the one hand the sleeve 20 with its (in Fig. 3 right)) rotary stop with the arms 23 and on the other hand the rotary damper 10 with its in Fig. 2 recognizable pin 27 engages in the mounting part 3.

In the Fig. 3 The opposite side, not shown, could in principle have a mirror-symmetrical design, that is to say it could contain a further rotary damper for the cover 1 and a further rotary stop for this. Alternatively, a rotary damper for the seat 2 could be provided on the opposite side. For this purpose, a rotatable connection between a sleeve (analog 20) and the cover 1 could be provided instead of the positive connection with the pin 11 (i.e. a rotationally symmetrical pin in a rotationally symmetrical receptacle) and also a non-rotatable connection between the seat 2 (i.e. the analog part) to 21) and a sleeve (similar to 20). Then, in particular, a rotary stop could also be present for the seat, as far as in Fig. 3 shown for the left side.

In a parallel application by the same applicant, a variant is shown in which, on the opposite side, a further rotary damper is provided for the seat 2, but without a rotary stop, and also a mechanism for the separability of the seat 2 and the cover 1 and finally the mounting part 3 from one another , This is not explained in more detail here.
