Description

The invention relates to a connecting corner for a drainage tray with the signs of the restrictive part of paragraph 1 of the claims. Such a connecting corner is known, for example, from CH 710 293 A2. The invention relates, in addition, to a tray section for such a connecting corner.

To drain surfaces, trays are usually used that, through gratings or slots, take in surface water and divert it by tilting toward the sewer. With straight trays, tilting is not a problem. In the corner areas of the tray system, that is, where the straight trays intersect at a certain angle, connecting angles that are not inclined are usually installed. Because of this, in the angular areas, water drainage is not supported due to the elevation difference, so that this can lead to accumulations of residual water and deposits. Therefore, from a hygiene point of view, the angular areas of the drainage system are critical.

The basis of the invention is the task of improving the connecting corner of the type indicated at the beginning in such a way that the flow of surface water in the corner regions of the tray system occurs reliably and hygiene problems are prevented or at least reduced.

According to the invention, this problem with respect to the connecting corner is solved by the subject of paragraph 1 of the claims, and with respect to the tray section by the subject of paragraph 11 of the claims.

This problem is solved, first of all, by means of a connecting corner for the drainage tray, which has two angled tray sections, each of which has side walls and the bottom of the tray. Tray sections form a supply hole and a drain hole of the connecting corner. For the formation of a height difference, the inlet opening and the drain opening are located at different levels relative to the reference plane. The base plane passes through the upper edge of the side walls. The bottom of the tray of each of the tray sections is formed of several bottom elements, which are located at an angle corresponding to the difference in height.

The invention has several advantages.

Firstly, the connecting corner, as such, is made with a height difference, since the supply opening and the drain opening are located at different levels. Therefore, the connecting corner can be installed horizontally, for example, to drain surface water from a horizontal platform, and due to the built-in height difference of the connecting corner, the surface water entering the connecting corner through the supply opening through the supply hole is reliably ensured and directed further to the sewer.

The supply hole and the drain hole are located at different levels relative to the reference plane, which passes through the upper edge of the side walls. This means that the connecting corner, as such, has a height difference and therefore can be oriented horizontally, that is, in the same plane with the surface to be drained. In other words, if the connecting corner is installed so that the upper edge of the side walls and at the same time the base plane passing through the upper edge of the side walls are horizontal, then the bottom of the tray is tilted. Then the inlet hole is located relative to the horizontal in the mounting position of the base plane higher than the drain hole, due to which the required height difference is obtained.

In addition, the invention provides that the bottom of the tray of each of the tray sections formed of several bottom elements. Bottom elements are interconnected and form together the bottom of the tray. The bottom elements are respectively inclined at least in the direction of the vertical difference between the supply opening and the drain opening. This ensures the most complete runoff of water flowing through the connecting corner.

The inclination of the bottom elements, at least in the direction of the elevation, means that the bottom elements can be further inclined in other directions to facilitate manufacture.

The compilation of the bottom of the tray from several bottom elements gives advantages in the manufacture of the connecting corner, since the connection at an angle, that is, the angular connection between both tray sections, can be accomplished by geometric adjustment and the corresponding inclination of the bottom elements. In other words, the bottom elements allow a certain break in the connection between the height difference of the bottom of the tray and the geometric constraints imposed by the side walls, since the inclination of individual bottom elements can be correlated with the overall inclination of the bottom of the tray, that is, with the height difference passing in the longitudinal direction of the corresponding tray section. For this, the individual bottom elements, at least partially, can be differently inclined relative to each other.

In a preferred embodiment, the angles of inclination of the bottom elements are oriented so that the drain hole forms the deepest place of the tray sections or the connecting corner. Due to such a slope of the bottom elements with a linear drainage of water in the region of the connecting corner, the surface water flowing into the connecting corner from any point of the connecting corner to the drain hole is reached (complete drainage of water).

The bottom elements, respectively of one chute section, advantageously comprise a first and second bottom element, which form an acute angle in the region of the outer corner edge of the chute section. This has the advantage that both bottom elements can be inclined in different directions.

In another exemplary embodiment, the bottom elements of a correspondingly chute portion may have a third bottom element. The first and second bottom element, as well as the third bottom element of one tray section, respectively, can form an acute angle in the area of the supply opening or in the area of the drain opening. In other words, at least three bottom elements of the chute section converge at an acute angle in the inlet region or in the region of the drain hole. This embodiment has the advantage that the supply opening or the drain opening can be well adapted to the contour of the corresponding adjacent tray. This is an advantage especially when the bottom of the corresponding adjoining tray is V-shaped. The acute angle formed by the three bottom elements in the area of the supply opening or the drain opening then passes to the end of the V-shape of the adjacent tray and, thus, to the deepest point of the bottom of the tray of the adjacent tray.

In a particularly preferred embodiment, the bottom elements are polygonal, especially triangular. The triangular shape of the bottom elements is particularly well suited to adjust the overall height difference in the area of the connecting corner due to the different inclination of the bottom elements, without needing to change the shape of the bottom elements during manufacture. Due to this, flat bottom elements can be used.

The corners of the first bottom element are preferably located in the region of the outer corner edge, in the region of the inner corner edge of the chute portions and in the region of the supply opening or in the region of the drain hole. Thus, the first bottom element forms the middle bottom element, primarily a triangle, which is in contact with the internal restrictions of the tray, that is, with the side walls and the edges of the supply opening or the drain hole only at the corners and, thus, pointwise. Due to this, the inclination of the first bottom element can be adjusted especially well, since the sides of the first bottom element are essentially separated from the contour of the internal restriction.

In addition, the edges of the supply opening or the edges of the drain opening are advantageously formed by the sides of the second and third bottom elements, respectively. Due to this, the connecting circuit of the connecting corner can be particularly well adapted to the connecting circuit of the drainage trays to be connected to the connecting corner.

In another preferred embodiment, the first bottom element of one tray section and the first bottom element of another tray section together form an isosceles triangle. The base of the isosceles triangle is adjacent to the inner corner edge, and the top to the outer corner edge. Due to this, a good transition of direct drainage trays is created, which are connected to the supply or drain hole of the connecting corner, since the isosceles triangle due to its position can be inclined both in the longitudinal direction of both tray sections and from the outside inward, that is, in the direction from the external corner edge to the inner corner edge.

The bottom elements of both tray sections can be located symmetrically. This embodiment is proposed especially when the connecting triangle is made symmetrical, that is, with tray sections of the same length.

The height of the side walls is advantageously correlated with the height difference. In other words, as the distance from the air inlet increases, the height of the side walls increases. The varying height of the side walls determines the gradient with which the elevation directs the surface water through the connecting corner.

In the framework of the invention, protection is claimed for a chute section that can be connected to another chute section in a connecting corner according to the invention. The chute section forms a base unit in the form of a straight elbow of the connecting corner. Therefore, the essential features and advantages of the chute portion are explained above in conjunction with the connection angle according to the invention. This is a reference. It should be noted that the inlet and outlet of a separate tray section according to the invention need not coincide with the inlet or outlet of the connecting corner. So, the drain hole of the water supplying chute section corresponds to the connection edge at an angle, that is, the oblique edge along which this chute section for making a connecting corner is connected to another chute section. Conversely, the supply air outlet of the water discharge chute section corresponds to the connection edge at an angle.

In the following, the invention is explained in more detail with further details with reference to the above schematic figures.

They show:

FIG. 1 is a perspective view of a connecting corner according to an embodiment of the invention, in which three bottom elements are provided in each tray section;

FIG. 2 is a plan view of the connection angle of FIG. 1 and

FIG. 3 is a perspective view of a connecting corner according to FIG. 1 with a direct drainage tray attached to it.

In FIG. 1-3 shows a connecting corner, which is used in drainage systems for linear water drainage. For this, the connecting corner is connected to two drainage trays, one of which is shown in FIG. 3.

The embodiment of FIG. 3 can also be understood as an L-shaped connecting corner, in which the longer elbow contains an additional straight groove section with integrated height difference.

The connecting corner has two, located in the form of an angle, specifically at a right angle, of the tray section 10, 11, which form the supply opening 14 and the drain opening 15. Through the supply opening 14, surface water flowing from the attached drainage tray (Fig. 3) flows into the connecting corner, changes the direction of movement in the connecting corner and flows out of it in another direction of flow through the drain hole 15, which can be connected to another drainage tray (not shown). Each individual tray section 10, 11 has two side walls 12a, 12b and a bottom 13 of the tray, which is located between both side walls 12a, 12b and forms a flow channel with them. The flow channel itself is in a known manner open upward, so that surface water from the sides and from above through the (not shown) grating can flow into the connecting corner.

In FIG. 1 and 3, you can clearly see that the bottom 13 of the tray connecting angle is inclined. For this, the supply opening 14 is located higher than the drain opening 15. The levels of the supply opening 14 and the drain opening 15 are determined respectively with respect to an imaginary reference plane that passes through the upper edge 17 of both side walls 12 a, 12 b. In other words, the distance from the bottom 13 of the tray to this base plane in the area of the supply opening 14 is less than the distance from the bottom 13 of the tray to the base plane in the area of the drain hole 15. This can be clearly seen in FIG. 1.

If the connecting corner is installed horizontally, that is, the base plane runs horizontally, then the necessary height difference is inevitably adjusted in the connecting corner. This height difference can also be clearly seen by the changing height of the side walls 12a, 12b, which, starting from the supply opening 14, increases in the direction of the drain hole 15.

The bottom 13 of the tray is formed from several bottom elements 16a, 16b, 16c.

Bottom elements 16a, 16b, 16c enable the formation of the necessary height difference, without the need for this to change the shape of the bottom elements in the manufacture of the connecting corner. Therefore, flat bottom elements can be used, which are connected with different slopes to form the bottom 13 of the tray. In this case, the bottom elements are inclined so that the drain hole 15 forms the deepest place of the connecting corner, so that the optimal water drainage in the corner regions of the tray system is facilitated.

In the original example of FIG. 1-3 bottom elements 16a, 16b, 16c are formed as triangular bottom elements. Other geometric shapes are possible.

The connecting corner shown in the figures has a total of six bottom elements 16a, 16b, 16c. Of these, respectively, three bottom elements 16a, 16b, 16c form respectively the bottom 13 of the tray of one tray section 10, 11. A different number of bottom elements is possible. First of all, it is possible to separate the individual triangular bottom elements 16a, 16b, 16c below. The bottom elements of the chute section 10, 11 have a first triangular bottom element 16a, which is located so that the corners of the first bottom element 16a are in contact with the internal restrictions of the connecting corner. This means that the lateral lines of the first triangular bottom element 16a are located at a distance from the internal limitations of the connecting corner, as can be clearly seen in FIG. 2. The corners of the first bottom element 16a are located specifically in the region of the outer corner edge 18, the inner corner edge 19 and the edge 20 of the supply opening 14 or the edge 20 of the drain hole 15.

Between the outer corner edge 18 and the inner corner edge 19, a connecting edge extends between the two trough sections 10, 11 of the connecting corner (angled connection).

The second triangular bottom element 16b is located between the first bottom element 16a and the outer side wall 12a of the corresponding tray section 10, 11. The outer side wall 12a of the corresponding tray section 10, 11 is a longer side wall. The inner side wall 12b is a shorter side wall.

Thus, the second bottom element 16b extends with one side line along the outer side wall 12a. Another side line of the second bottom element 16b forms a connection with the first bottom element 16a. The third side line of the second bottom element 16b forms a part of the edge 20 of the supply opening 14 or a part of the edge 20 of the drain hole 15.

Accordingly, the third triangular bottom element 16 c is located between the first bottom element 16 a and the inner side wall 12, that is, the short side wall 12 b of the connecting corner. One side line of the third bottom element 16 c also extends here along the inner side wall 12b. Another lateral line of the third bottom element 16c forms a connection with the first bottom element 16a. The third side line of the third bottom element 16c forms a part of the edge of the air inlet 14 or of the drain hole 15, so that the second and third bottom elements 16b, 16 c together form the bottom edge of the air inlet 14 or of the drain hole 15.

As can be well seen in FIG. 2, the angles of the first and second bottom elements 16a, 16b in the region of the outer corner edge 18 extend together. This applies to the first and second bottom elements 16a, 16b of both chute sections 10, 11, so that a total of four bottom elements are found in the region of the outer corner edge.

Four bottom elements also occur in the region of the inner corner edge 19, namely, the first bottom elements 16a and the third bottom elements 16 from the tray sections 10, 11, respectively.

The first two bottom elements 16a of the chute sections 10, 11 together form an isosceles triangle, the base of which contacts in the middle with the inner corner edge 19 or shares it in the middle. The connecting line between the two first bottom elements 16a, 16a simultaneously forms a connecting line between the inner corner edge 19 and the outer corner edge 18.

The bottom elements are inclined so that, on the one hand, they contribute to the longitudinal height difference of the corresponding chute section 10, 11. On the other hand, the bottom elements are at least partially inclined inward, in the direction of the central longitudinal axis of the corresponding chute section 10, 11, so that surface water can flow both from the supply opening 14 to the drain opening 15, and from the side walls 12a, 12b inward.

The arrangement of the bottom elements in the region of the inlet 14 or the drain hole 15 is such that located in the region of the inlet 14 or the drain hole 15, specifically on the corresponding bottom edge 20, the angle of the first bottom element 16a coincides with the deepest point of the attached drainage tray, as can be clearly seen in FIG. 3. In addition, the edges 20 of the inlet opening 14 or the drain opening 20 are inclined at the same angle as the bottom of the tray of the V-shaped drainage tray, which is connected to the connecting corner. The inclination of the edges 20 of the supply opening 14 or the drain opening 15 can be clearly seen in FIG. 1.

The arrangement of the bottom elements 16a, 16b, 16c of both tray sections 10, 11 is essentially the same.

The exemplary embodiment of the invention has the advantage that not only is the surface water optimally discharged in the connection angle, but also that, despite the integrated height difference, it is possible to produce the connection angle essentially without delay.
