INNOREC SA NICE / France

Odor trap for sink or the like.

The invention relates to an odor trap according to the preamble of claim 1.

Such devices allow objects, for example a ring, which have accidentally fallen into the collecting container can be removed from the collecting container without dismantling the arrangement by placing it in its removal position

the object

brought and / after removal of the cap that normally closes the removal opening is removed through this opening will. In a known odor trap of this type, the collecting container is from his normal working position by 90 after the one and the other direction in its emptying position or in its removal position can be pivoted, one being quite constructive Complicated cam guide ensures that the container is simultaneously shifted or tilted when it is tilted. Undergoes translation. This complicated movement of the bin takes into account the fact that the dip tube protruding into the container follows the tilting of the container

0909 / 1242.12D.1 - Bll / jO / eb

must not interfere in both directions.

The invention is based on the object of the structural design and the handling of an odor trap of the introduction to simplify the type described and a particularly suitable, easy to assemble for an economical series production and to create robust apparatus.

To solve this problem, the odor trap according to the Invention characterized by those features which are specified in the characterizing part of claim 1.

This creates a complicated cam guide for the collecting container avoided in its pivoting movement, because the container is only a simple rotation when turning the operating button Executes fixed axis, and for assembly need the non-rotatable connection between the axis and the container forming correspondingly profiled coupling steeply just plugged into one another to become. The user also only needs to pivot the collecting container to one side, regardless of whether the container is in the emptying position or wants to move into the removal position, which simplifies handling.

Preferably, a return spring is provided that the collecting container returns to its normal position as soon as the control button is released in the removal position or the emptying position. Otherwise the user might forget to turn the container back into its normal position from the removal or emptying position. The removal position can however, be defined by a slight detent, which, however, allows the container to be automatically returned to its normal position when the control button is released. On the other hand, blocking can also occur in the removal position.

409836/0404

be seen that the container remains in this position until the user operates the button again this blockage is released so that the container then returns to its normal position under the action of the return spring.

Further features of the invention emerge from the subclaims.

and FIG. 16 shows two views of a second embodiment of one

Detent spring. "

According to the Fig. ' 1 to 3, the device has an approximately rectangular, on one narrow side open housing 1 and this open narrow side covering and under.intermediate circuit a seal by means of screws 10 on the housing 1 attached cover 2. ' The housing 1 has an inlet 3 on its top, through which a removable immersion tube 5 protrudes into the interior of the housing, in the lower region of the one opposite the cover 2 Narrow side an outlet 4 and on its two side surfaces opposite one removal opening 6, which are at least partially is located above the area of the outlet 4 and is covered by a removable, tightly fitting cap 34. "The immersion tube 5 stands via a telescopic tube 11, which can be fastened by means of union nuts 12, to the drain of the wash basin or a other sanitary facility in connection, while the drain 4 is connected to the sewer. "

In the housing 1, a collecting container 7 is arranged, into which the immersion tube 5 protrudes and which is defined by two pins 8, 8 ¹ (pig, ' 3) rotatable in openings 16 of the two opposite side walls of the housing around a transverse axis in Fig. ' 2 normal position shown with solid lines can be tilted clockwise, 'In Fig, "2 the emptying position and the removal position between this emptying position and the normal position are indicated by dash-dotted lines," The pins 8 and 8 ¹ are indicated non-rotatably connected with an outer actuation button 9 or "9 *." The non-rotatable connection between the collecting container 7 and the pins 8 and 8 * takes place by means of

409836/0404

two complementary profiled parts, which are formed by two opposite flat flats 8c at the inner end of each pin ^ on the one hand and by a corresponding recess 13c (Fig. 2) provided in one / on both side walls of the container 7 formed projections 13 on the other hand. The inner pin end and the recess 13c on the container 7 are thus each delimited by two opposite parallel walls and curved wall sections connecting them on both sides. For assembly, the inner end of the pin 8, after the container 7 has been inserted through the open narrow side wall of the housing 1, only needs to be pushed into the recesses 13c, which guarantees a robust, non-rotatable connection between the pin 8 and the container 7 is. In the middle of the recess 13c there is a cylindrical projection 13a which engages in a corresponding cylindrical recess 8a at the inner end of each pin 8 or 8 '. The outer ends of the two pins 8 and 8 'are designed as a square 8b and each serve to accommodate an outer actuating button 9 or 9 ¹ (FIGS. 1, 3 and 7), which for this purpose has a corresponding square opening 14 on its inside has, in which the square 8b engages, by means of a central countersunk screw 15 which penetrates the pin 8 and is screwed into a corresponding Ge thread opening of the cylindrical projection 13a on the container sides, the actuating button 9 or 9 ^{1 is} held, which in this way simultaneously is rotatably connected to the relevant pin 8 or, 8 '.

The geometrical shape of the container 7 which can be seen in FIG. 2 and the position of its axis of rotation in the vicinity of the emptying side remote end of the container allow perfect tilting to one side without obstruction by the dip tube 5, such as

409836/0404

indicated in Fig. 2, and at the same time convenient accessibility of the container in its middle removal position through the lateral removal opening 6. For this purpose, the Container 7 has two parallel side walls, a rounded bottom 7a, a vertical one that ends at this bottom Narrow side wall 7b and a straight narrow side wall 7c inclined towards the other bottom side, which is located on the emptying side of the container. In the emptying position indicated in FIG. 2 closes this narrow side wall 7c with the lower wall of the housing a small acute angle, which prevents any larger coherent impurities located in the container 7 or objects that have fallen into this emptying position are flushed out with the drain 4 "send water and can clog the pipe; such impurities or objects can be passed through the removal opening beforehand 6 or 6 'removed v / earth »This emptying position can for example by stopping the container wall on the bottom of the housing 1 or on the inner wall dss cover 2 or be defined by ir gentle infände ren. stop. The normal one The working position of the container 7 is, for example, due to the plant a projection 33 formed on the upper edge of the container (Figs. 2 and 3) defined on the top wall of the housing 1 or by another suitable stop.

Between the one actuating button 9 'and the adjacent outside of the housing 1, a return spring 27 (FIG. 8) for the container 7 is arranged. This spring consists of a coil spring, which, for example, only needs to have a single turn and has ends 28 and 29 which are elongated in a straight line. One end of the spring 29 engages in a corresponding groove 31 on the inside of an operating handle 32 molded onto the operating button 9 '(FIG. 7) >

409836/0404

while the other spring end 28 engages in a corresponding groove 31 which, according to FIG. In this way, the return spring located 27 in the assembled state of the device as shown in Fig. 3, in one the pin 8 'surrounding and covered from the operation button 9 ¹ annulus and ensures that after pivoting of the container 7 from its normal position against the action the return spring 27 automatically turns the container 7 back into its normal working position after releasing the operating button. This prevents the container 7 inadvertently remaining in a position other than its normal working position, which of course would impair the function of the odor trap.

In the exemplary embodiment under consideration, there is also a latching device provided, which defines the removal position of the container 7. This latching device can be designed so that in the removal position of the container 7 effective elastic latching force is less than the restoring force of the return spring 27, such that after releasing the operating button, the return spring 27 automatically for a pivoting back of the container 7 in its normal Working position ensures. On the other hand, however, the latching device can also be designed so that the container 7 is in its removal position remains blocked and that the user must first turn the operating button a little further in the direction of the emptying position and then you have to let go in order to pivot the container 7 underneath the action of the return spring in its normal working position cause.

409836/0404

Ια has both cases according to the embodiment described. this latching device has a latching spring, which is an essentially flat spring 17 or 36 of the type shown in FIG. 10 or in FIG. represented form can act.

•May

The detent spring according to FIG. 10 is approximately S-shaped Leaf spring, each of which has a projection 20 protruding from the spring plane at its two ends and a square opening in its center 18, which is adapted to the square 8b of the pin 8. The other embodiment of a detent spring 36 according to FIG. 15 consists from a flat ring 37 formed by deformation at two diametrically opposite points, from the ring plane projections 38 protruding on one side and with a diametrical transverse rib 39 »which is deformed out of the ring plane on the other side and with one of the square 8b of the pin 8 adapted opening 40 is provided.

In the assembled state, the detent spring located on the inside of the actuating button 9 according to FIG. 3 is pushed with its central opening 18 or 40 onto the square 8b of the pin 8 and thus non-rotatably connected to the pin 8 and works with its projections 20 or 38 with integrally formed on the outer wall of the housing 1 approaches or stops together. The arrangement is therefore made that the latching device within the one actuation button 9 and the return spring 27 within the other actuation button 9 ^! is mounted.

In the following, the one is initially based on FIGS. 4 and 12 to 14 Described form of a latching device in which the collecting container 7 is blocked in its removal position. For this purpose, a freely rotatable about the pin 18 disk 21 (Fig. 9) with two diametrically opposite radial projections 22 within the loading

409836 / 04CU

operation button 9 on a corresponding ring projection of the housing 1 stored (Fig. 3), the Radialvor jumps 22 with a certain play between each two on the housing wall molded stops 23 and 24 or 23 'and 24' (Fig. 4) engage, so that the free rotation of the disk 21 is limited by these stops. Furthermore, according to FIG. 4, on the housing wall two further diametrically opposed stops 25 and 25 'are integrally formed. The stops 23, 24 and 25 are together with the one Radialvor jump 22 of the disc 21 on that arc, which the one projection 20 or 38 of the detent spring describes when the actuating button 9 is rotated for the purpose of rotating the collecting container 7, while the other group of housing lugs 23 ', 24' and 25 'together with the other Radialvor jump of the disc lie on the corresponding arc described by the other projection of the detent spring. The middle approach 23 is on the side facing the stop 25 by a against the housing wall inclined surface 26 bounded by a surface section 26a oriented parallel to the housing wall, whose edge facing the stop 24 and oriented essentially at right angles to the housing wall provides a blocking stop for forms the locking spring end. Analog is the approach 23 'by an inclined Surface 26 'and an adjoining surface 26'a parallel to the housing wall are delimited.

The blocking of the collecting container 7 in its removal position and the unlocking of the collecting container from this position is described with reference to FIGS. 12 to 14, which act on the detent spring 17 with the spring projections 20 reference, but exactly the same applies to the detent spring 36. In addition, only on the interaction of a spring projection 20 with the a group of housing stops 23,24 and 25 and with a Radialvor jump 22 of the disc 21 is referred to, as on the

409836/0404

2409323

to the axis 8 diametrically opposite side always at the same time the same thing playing.

lh the normal working position of the collecting fairy rs 7 is behind 12 shows the locking spring projection 20 on the housing stop 25. "If the operating button 9 in the illustration of FIG. 2 and the Figures 12 to 14 is rotated clockwise, then the locking spring projection 20 slides under after reaching the housing extension 23 corresponding spreading from the housing wall along the inclined surface 26 (FIG. 4} and then onto the surface section 26a this approach 23, while at the same time the disk 21 is carried along by ribs up to the contact of the radial projection 22 on the housing stop 24 becomes, (Fig. 13). In this way it is ensured that between the Radialvor jump 22 of the disk 21 and the housing approach 23 forms a gap into which the locking spring projection engages when it is turned from the operating button 9 by further turning Surface section 26a of the projection 23 slips off. Its anscfalagskante therefore forms a block for the detent spring and thus for the collecting container 7 in its removal position. Around the collecting container 7 to return to its normal working position is sufficient it when the operating button 9 is initially rotated further through a small angle in the direction of the emptying position and then simply is released. When the actuating button is turned further, the locking spring projection 20 slides out of the mentioned gap out and on the Radialvor jump 22 of the disc 21 (Fig. 14), and if now the control button is released, all rotatable parts under the action of the return spring 27 rotated back into their original position, because the disc 21 in turn Friction from the detent spring to the stop of the radial jump on the housing stop 23, i.e. until the mentioned I / Soke closes, is taken, whereby a possible blockage of the detent spring

A09836 / 0A04

projection 20 on approach 23 is omitted. The arrangement described is therefore made so that the blocking of the collecting container in its removal position defining locking gap for the locking spring approach 20 (or 38) is only opened when the collecting container is pivoted against ^ the action of the return spring 27; as soon as on the other hand, the collecting container is slightly rotated beyond its removal position or up to its emptying position and then the operating button is released, this locking gap closes automatically. so that the collecting container is under the action of the return spring 27 will definitely return to its normal working position.

The second mentioned embodiment of a locking device, which after releasing the actuation button an immediate automatic Resetting of the collecting container in its working position under the action of the return spring 27 allows, differs from the above described embodiment only in that the surface section 26a of the housing extension 23 (Fig. 4) to the surface section 26 oppositely inclined surface, so that the extension has a V-shaped profile protruding from the housing wall ^ · If in this case the locking spring end 20 or 38 when rotating the Collection container 7 has passed the first inclined surface 26 and over the stop edge common to the two inclined surfaces of the projection 23 then the user feels a certain sudden reduction in the force counteracting further rotation of the actuating button, possibly also a certain reduction Snapping sound of the detent spring, which shows him the removal position, which is also preferably natural, as well as the normal Working position and the emptying position, through a marking on the outside of the housing for the corresponding angular position the operating handle 32 of the operating button is displayed »In this embodiment, the restoring force is the return spring 27 larger than that given by the tension of the detent spring and the inclination of the surface 26a of the projection 23, in the removal ■ position of the collecting container effective locking force, so that after

409836/0404

Letting go of the operating button, the detent spring end under the restoring force of the return spring over the inclined surface 26a can slide away. In this last-described embodiment, the disk 21 (FIG. 9) can of course be omitted, and the housing stop 24 or, 24 'serves to rest the locking spring end in the emptying position of the collecting container. If how described, the normal working position and the emptying position of the collecting container already defined by other stops the housing shoulders 24 and 25 or 24 'and 25' can optionally be dispensed with.

In the cover 2 of the housing 1 there is also a diaphragm valve (Fig. 2) arranged, which prevents unpleasant suction noises in the event of a rapid drainage of water through the outlet 4 by being at The creation of a negative pressure in the housing 1 allows air to enter this housing.

In a simplified embodiment, the odor trap has according to the invention no locking device and possibly only a return spring.
