Description

Title: Assembly of a drain and a stench lock, as well as a floor provided with such an assembly and a method for the manufacture of a stench lock.

The invention relates to an assembly of a drain and a stench lock, wherein the drain is provided with a liquid collection space with a liquid drain for collecting and discharging liquid, the stench lock being arranged to close said drain substantially odor-free using liquid collected in the collecting space, wherein the stench lock successively comprises at least a substantially upward, downward and upward liquid path, such that at least a double stench locking action is thereby provided during use.

Such an assembly is known from the French patent application FR 2 740 792. The advantage of the known assembly is that it is provided with a stench lock with a double stench lock action, which effectively prevents the spread of unpleasant odors from the discharge.

A drawback of the known assembly is that the assembly is relatively difficult to clean. Therefore, dirt can easily accumulate in the assembly, which impedes the liquid discharge capacity of the assembly. The drain and / or the odor trap can, for example, become clogged, so that liquid drainage is no longer possible.

The present invention has for its object to eliminate the aforementioned drawbacks of the known assembly while maintaining the advantages thereof. In particular, the invention contemplates an assembly of a drain and a stench lock, with which the spread of stench can be properly prevented and with which clogging of the assembly can be combated well.

To this end, the assembly according to the present invention is characterized in that the stench lock - generally after assembly - is releasably placed in the drain, such that the stench lock can be taken out of the drain.

Because the stench lock is removable from the drain, the stench lock can be cleaned easily, thoroughly and quickly outside the drain. The drain can herein remain substantially simple in an assembled position, for example in a floor or the like. In this way, blockage of the assembly can be effectively eliminated. Preferably the drain as such is also cleaned after the stench lock has been removed from the well. After cleaning, the stench trap can be set up again in the drain and provided with liquid to close off the liquid drain from the well. Because the stench lock can be placed in the drain, the assembly can easily be mounted in a desired position, for example on or in a floor. Furthermore, the assembly can simply be provided with a relatively small built-in height, while maintaining a long-lasting stench lock effect, by using a stench lock with at least a double stench lock effect.

Said liquid collection space of the drain can, for example, be accessible via an access from an environment to remove the stench lock from the drain and to place it back in the liquid collection space. Preferably, said access can be closed, for example through a suitable grid, cover or the like, so that liquid evaporation of liquid present in the drain, in particular liquid present in the collecting space and / or the stench trap, can be inhibited or prevented.

According to a preferred embodiment of the invention, said stench lock is provided with at least two releasably coupled housing parts.

As a result, the stench lock can easily be opened for cleaning the interior of the lock. The stench lock preferably consists of two releasably connectable parts, so that the stench lock can be made relatively cheaply, simply and durably. It is then advantageous if the two housing parts have the same shape and dimensions. As a result, the housing parts can be manufactured in large quantities in a particularly inexpensive manner, for example by injection-molding the housing parts with the same mold In addition, the stench lock can thus always be assembled from two usual parts, which makes mounting the stench lock uncomplicated.

The invention further provides a floor characterized by the features of claim 28.

Because the floor is provided with an assembly according to the invention, the above-mentioned advantages are offered to the floor. Because the said assembly can be provided with a relatively small installation height, the floor can be made relatively thin. Thin floors are, for example, advantageous in buildings with many floors, for example with a view to saving space. Moreover, floor material can be saved by making the floor thin. This offers the further advantage that the floor can be of such a relatively lightweight design, in particular if the floor is a concrete floor. Moreover, such a lightweight floor in itself only needs a relatively light bearing construction, which leads to a further saving of material, space and costs. The floor can for instance comprise an inner floor, outer floor, balcony floor, terrace floor and / or another floor.

The invention further provides a method characterized by the features of claim 33.

Because the stench lock is injection molded, the stench lock can be manufactured relatively easily, simply and accurately. As mentioned, different components of the stench lock are preferably injection molded with the aid of one mold, which leads to relatively low costs of manufacturing the stench lock.

Further elaborations of the invention are described in the subclaims. The invention will now be elucidated on the basis of two exemplary embodiments and the drawing. In the drawing: Fig. 1 shows a perspective front view of a first exemplary embodiment of the invention, in a mounted state; Fig. 2 shows such a view as Fig. 1 of the first exemplary embodiment in an exploded position; Fig. 3 is a top perspective view of the drain of the exemplary embodiment shown in Fig. 1; Fig. 4 is a front view of a housing part of the stench lock of the exemplary embodiment shown in Fig. 1; Fig. 5 is a top view of the front view shown in Fig. 4; Fig. 6 is a side view of the top view shown in Fig. 5; Fig. 7 is a sectional view of the first exemplary embodiment shown in Fig. 1; and Fig. 8 schematically shows a vertical section of a second exemplary embodiment of the invention.

Figures 1, 2 and 7 show an assembly 1 of a drain well 3 and a stench lock 2. The drain well 3 is adapted for, for example, to be built into a floor or the like, for instance for draining liquids on the floor. The well of the present exemplary embodiment comprises a substantially cylindrical chamber 3 with a block-shaped side chamber 9 which are in open communication with each other. Both chambers 3, 9 surround a liquid collection space 4. The side chamber 9 is provided in a wall 14 remote from the cylinder chamber 3 with a liquid discharge, comprising a discharge opening with a substantially horizontal, cylindrical discharge piece 8. The discharge 8 can for instance be mounted after mounting connected to one or more drain pipes, reservoirs or the like, not shown.

1025653 5

FIG. 1 shows the assembled position of the assembly 1. In this position, said cylindrical chamber 3 is closed at the top by a cover or grid 5 provided with liquid passages 6. The grid 5 is releasably arranged on a cover profile 7 of the cylinder chamber 3. The cover profile 7 is provided with a square outer edge for processing in a tile floor or the like.

The grid 5 can be removed from the well 3 to gain access to the fluid collection space 4. Such access is, for example, desired to clean the fluid collection space 4. In addition, such access is advantageous for removing the stench lock 2, which is explained in more detail below.

During use, liquid can flow in from a cylinder chamber 3 mentioned via the grid 5. After reaching a suitable liquid level, the liquid can pass through said stench lock 2 and reach the outlet 8.

The stench lock 2 is arranged to close the drain 8 of the drain 3 substantially odor-tightly using the liquid collected by the drain 3. As shown in Figure 7, for this purpose, the stench lock 2, viewed in a downstream direction towards the drain 8, comprises alternately a substantially upward and a downward liquid path.

In the exemplary embodiment, a first substantially upward path K1, a downward path K2 and a second upward fluid path K3 are provided in succession. Therefore, the stench lock 2 can provide a double stench lock action.

The present odor trap 2 in the assembled state consists of

a block-shaped lock housing delimiting said fluid paths K1, K2, K3. The housing 2 consists of two releasably coupled to each other, preferably injection molded, plastic housing parts 2A, 2B. Said two housing parts 2A, 2B have the same shape and dimensions. The shape of each of the housing parts 2A, 2B is shown in Figures 4-6. Each housing part 2A, 2B

> 1025553 6 comprises a bottom 20 and two opposite side walls 21, 22 which extend perpendicular to the bottom 20. The edge remote from the bottom 20 of one of the side walls 21 of each housing part 2A, 2B is provided with complementary projections 13 and recesses 14 for positioning the housing parts 2A, 2B relative to each other. Each of said housing parts 2A, 2B is provided with a vertical partition 12A, 12B extending perpendicularly between the side walls 21, 22 to separate said sections K1, K2, K3. The partitions 12 are designed higher than the side walls 21, 22, so that the partitions 12, after mounting, extend a certain distance in the opposite housing part 2B, 2A.

Said distance is such that a liquid passage is available between the partition 12A, 12B and the bottom 20 of the opposite housing part 2B, 2A.

The housing parts 2A, 2B are moreover arranged such that the housing 2 assembled therefrom is provided near a bottom side of the upstream, ascending liquid path K1 with a liquid inlet for receiving liquid from said liquid collecting space 4. Moreover, the composite housing 2 is provided near a top side of the downstream, ascending path K3 with a liquid outlet 20 for supplying liquid to said outlet 8. For this purpose each housing part 2A, 2B comprises an end wall 11 which has the same height as the partition 12.

The two housing parts 2A, 2B can be connectable to each other in various ways. For this purpose gripping means, clamping means, connecting means, snap connections, screws, nuts, coupling pins and / or the like can be provided, for example. Furthermore, the housing parts 2A, 2B can for instance be adapted to hold each other with clamping force. Furthermore, the housing parts 2A, 2B can for instance be provided on the inner sides with guide slots (not shown) for sliding in the parts of said partitions 12 and / or end walls 11 extending above the side walls 21.

10255 b 7

The stench lock 2 can be releasably placed in the liquid collection space 4 of the drain 3. The drain 3 and the stench lock 2 are particularly adapted to cooperate with each other in such a way that the stench lock 2 can be kept in the liquid collecting space 4 as a result of this cooperation in the position suitable for stench sealing, shown in FIG. For this purpose, the assembly can for instance be provided with at least one clamp and / or snap connection to keep the stench lock 2 easily releasable in the drain 3.

As Figures 2-7 show, the present lock housing 2, at its assembled state, is partially slidable in the side chamber 9 of the present drain 3. The side chamber 9 may, for example, be arranged, for example suitably dimensioned, to engage the lock housing 2 for releasably retaining the lock housing 2.

In the exemplary embodiment, the drain 3 and the stench lock housing 2 are moreover adapted to connect to each other in a substantially fluid-tight manner. To this end, the lock housing 2 and / or a lateral chamber 9 engaging therewith may be provided with, for example, somewhat resilient material. In addition, for example, sealing means (not shown), for example grooves extending resiliently, or the like, can be provided for effecting a fluid-tight seal between an outside of the lock housing 2 and an inside of the drain 3. Such a fluid-tight seal can prevent odor from flowing from the drain 9 between the lock housing 2 and the inside of the drain well 4 into an environment. Such a closure, for example a resilient sealing ring, can also serve as a coupling to keep the stench lock 2 releasably in the drain 3.

The present assembly 1 is provided with spacing means 10 for maintaining the stench lock 2 at a certain distance L from the drain 8 in T025 * 8 the drain well 3. In the present exemplary embodiment, these spaced means comprise a number of cams 10 which are located on the inner sides of the side chamber 9. Such spacing means can of course be designed in various other ways and be provided, for example, on the stench lock 2.

During use, at least after assembly, the paths K1, K2, K3 of the stench lock 2 from the liquid collection space 4 can be filled with liquid up to a certain maximum filling height Hmax. At a higher liquid level, liquid from the stench lock 2 can first flow into a downstream part of said side chamber 9 and then the drain 8. When the stench lock 2 is filled with sufficient liquid, the stench lock provides a double stench trap. On the other hand, there is a gas connection between said liquid collection chamber 4 and the discharge 8 when the sections K1, K2, K3 are filled with liquid below a minimum filling height Hmin.

Due to the at least double odor trap, the assembly can be made relatively low. The installation height of the assembly 1, indicated by an arrow T, is preferably no more than approximately 55 mm. For this purpose, the difference between the maximum and minimum filling height of each upward path K1, K3 may be smaller than approximately 25 mm. With such a difference in maximum and minimum filling heights, the stench lock 2 can still provide a desired, relatively long stench seal for the drain 8.

Because the stench lock 2 is releasably placed in the liquid collection space 4 of the drain well 3, the stench lock 2 can be taken out of the drain well 3, while the drain well 3 can remain substantially at a desired mounting position, for example in a floor or the like.

For the purpose of removing the stench lock 2, the grid 5 can simply be removed from the well 3. The stench lock 2 can then be slid out of the side chamber 9. Then the two halves 2A, 2B

1025553 9 of the stench lock 2. Due to the described embodiment of the stench lock 2, all inner surfaces of the stench lock 2 are directly accessible from an environment at the disassembled position of said housing parts 2A, 2B. The term "directly accessible" is understood to mean that said inner surfaces are substantially not shielded from the environment at said disassembled position of the lock 2. Therefore, the stench lock 2 is particularly easy to clean at that detached position. After cleaning the interior of the housing parts 2A, 2B, the housing 2 can again be assembled from those parts 2A, 2B, to be subsequently returned to the position shown in Fig. 7. Finally, the grid 5 can again be placed on the well 3 for use of the assembly 1.

Figure 8 shows schematically a second exemplary embodiment of the invention. The second embodiment comprises an outer floor 50 of a building G, for example a balcony floor and / or a roof floor or the like. The floor 50 extends, for example, along an outer wall M of the building. The outer wall M comprises a passage with a door 43, for example a front door, gallery door, balcony door, roof terrace door or the like, and a door threshold 42 extending along the floor 50.

The outer floor 50 is provided with a water well 1. The water well 1 is arranged in the floor 50 at a distance from a wall M of the building G, for example on or near a side of the outer floor 50 remote from the building G. As figure 8 shows, the outer floor 50 is adapted to feed water collected on the floor 50 to the drain 1. To that end, the outer floor, viewed from the outer wall M of the building G, slopes slightly obliquely. In particular, the upper surface of the floor 50 encloses an angle α with a horizontal plane, which angle α is, for example, in the range of approximately 1-10 °, in particular in the range of approximately 1-5 °. In this way it is moreover simple to prevent rain water, for example, from building up on the floor 50 on the wall side of building G, so that water breakdown, mold, leakage along door threshold 42 and the like can be avoided. It is also possible to comply with legal regulations with regard to a maximum permissible threshold height of the door threshold 52. Because the water can be discharged from the wall M via the floor 50, the door threshold 52 can in particular be made relatively low, which for safety reasons, among other things.

The drain 1 arranged in the outer floor 50 advantageously comprises an assembly according to the present invention, for example the assembly 1 shown in figures 1-7. The installation height of the assembly 1 is relatively small, preferably less than approximately 55 mm. The drain 9 of the assembly 1 is connected to a water drain pipe 51 which extends slightly obliquely downwards. The discharge pipe 51 in particular encloses an angle β with a horizontal plane, which angle β is in the range of approximately 1-10 °, in particular in the range of approximately 1-5 °.

Sufficient slope is therefore available to drain rainwater collected by the assembly 1. Downstream of the drain pipe 51, for example, a vertical drain 54 is arranged for further drainage of the water.

The water drain 51 preferably extends completely into the outer floor 50, as is shown schematically in Figure 8. The advantage of the exemplary embodiment shown in Fig. 8 is furthermore that the floor 50 can be of relatively thin and lightweight design, wherein the water discharge 51 can nevertheless extend substantially entirely in the floor 50 and also ensure a good water discharge.

It is self-evident that the invention is not limited to the exemplary embodiments described. Various changes are possible within the scope of the invention as set forth in the following claims.

1025553 11

For example, the stench lock 2 may consist of different releasably connectable parts. These parts can for instance comprise parts which can be brought onto each other in a vertical direction, for instance an upper housing part and a lower housing part. In addition, the parts of the lock 2 can for instance be connectable to each other in the horizontal direction and / or in another direction.

The different parts of the stench lock can each be manufactured in different ways, in different shapes and / or from different materials. For example, said housing parts can also have different dimensions and / or shapes. Furthermore, said lock housing per se can for example be angular, round, block-shaped, cylindrical, straight, curved and / or otherwise shaped. Said chamber of the stench lock can for instance be cylindrical, angular, square, straight, curved and / or otherwise shaped.

Moreover, the stench lock can for instance be made of one or more plastics, metals, alloys, steel and / or a combination of these or other materials.

Furthermore, said liquid paths K1, K2, K3 of the stench lock can extend, for example, in substantially vertical direction and / or enclose certain angles with a vertical plane. Moreover, said substantially upward and downward paths K1, K2, K3 may be in fluid communication with each other in various ways, for example directly and / or by means of substantially horizontal intermediate paths or the like.

Said liquid discharge from the drain can be designed in various ways. The drain can for instance comprise a side piece 8, 9 or the like from a liquid collection chamber 3. In addition, the drain can for instance comprise an opening of the wall of the liquid collection chamber 3 or the like.
