Description

The invention relates to a height-adjustable drainage grate for balconies, patios and the like with a walk-in, with a large number of drainage openings and one two elongated, facing each other and essentially parallel to each other running support profiles for use vertical support of the web part Support structure, on their in use position bottom facing bottom a number of one each Threaded shaft and in corresponding thread receptacles guided feet is provided, one at the same time on one profile section of each of the two support profiles Slidable sliding part is provided, which a crossbar with two on opposite edges of the Transversely arranged receptacle for each of the profile sections of the two support profiles, and on the Cross bar at least one, preferably two threaded receptacles are provided for the threaded shafts of the feet.

Height-adjustable drainage grids are used in particular to in the door area of balconies, patios and the like a drainage option to create, so by the DIN 18 195 (Part 5, point 7.1.6) can be deviated, after which seals in the door and wall connection area at least until at 15 cm above the top edge of the respective floor covering must be brought up, what high and dangerous trip hazards in the door area of the respective balcony, the Terrace or the like conditionally. According to the flat roof guidelines, 10.3. (4) may deviate from the mentioned DIN standard, if "... in the immediate door area ... drainage options ", such as those mentioned above Drainage grates can be created.

The height-adjustable drainage grates that are mainly used today have a support and frame construction Support profiles and cross struts, in which a walk-in Web part forming grating can be inserted and on the bottom of which several with a threaded shaft Provided feet are provided for height adjustment each more or less far in the corresponding thread receptacles can be screwed in. The well-known drainage grates have proven themselves in practice and have been that is why it has been used increasingly in recent years, especially with them also handicapped and elderly, Have tripping edge-free solutions implemented. It exists therefore an increased demand for such drainage grates, but so far only in certain standard widths and lengths are available. Since the drainage grates in their respective corner areas are supported by the feet must be accessible so that the corner areas of the web part can also be walked on remain, and since the thread receptacles are each rigid with the Support structure connected can be of standard sizes deviating drainage grids are not easy to get through Cut to length of a standard grate.

DE-U 93 13 697 is a drainage grate at the beginning known type, in which the receiving the web part Support profiles with horizontal in the use position running elongated holes are provided through which the Threaded shafts can be passed through fastening screws which are further through vertical slots in the side Legs of U-brackets can be passed, with which the Support profiles are supported on the ground on the ground. By tightening one on the free end of the threaded screw the fastening screw screwed on nut are the U-bracket when the nut is still loose selectable longitudinal and height positions can be fixed. Indeed is also a horizontal one in the position of use Slidability of the U-bracket only within the specified Length of the elongated holes provided in the support profiles possible. Any cut to length of the support profiles for adaptation to predetermined, from the normal length of the known Drainage grate different length of the web part with the Possibility to put the U-bracket in the corner areas of the web part to move, is also in this drainage grate design not guaranteed in every case. In addition, at this configuration with a longitudinal adjustment of the U-bracket with the nut of the fastening screw loosened, also an adjusted one Height adjustment of the support profiles in the U-brackets solved so that after horizontal adjustment in in any case, a new height adjustment is required is before the nut of the fastening screw is back Fixation of the changed longitudinal position can be tightened can.

Proceeding from this, the object of the invention is a height-adjustable drainage grate of the aforementioned Specify the type, which in any, respectively required Lengths can be shortened without causing problems would result in the support of the corner areas by the feet.

Starting from a drainage grate of the type mentioned This object is achieved in that the Threaded shafts run perpendicular to the sliding part, height adjustment of the drainage grate is possible by turning the feet more or less far into the thread receptacles. Such a configuration allows one Shorten drainage grate to a required length and then postpone the sliding part and the corner area on which was shortened by means of attached to the sliding part Support feet. In addition, such Sliding part also at the joint of two juxtaposed Drainage grates are used in such a way that each half on the support profiles of one and the other Drainage grate is pushed on, it then the drainage grate advantageously aligned and aligned in addition, the number of support points at the joint of the two drainage grates required, usually by 50%. It also will possible, at certain, predetermined positions feet entirely provided along the support structure to do without and thus the entire support structure and the manufacture and installation of the drainage grate simplify. The support structure and the walk-on bridge part can then namely in any, even very large Lengths are produced, which the processor envisages Can shorten the location to the size he needs, whereupon he then depending on the length of the drainage grate at least two and if necessary, slide on further sliding parts and to the desired ones Positions positioned.

The invention can thereby advantageously be further developed be that at least one, preferably both shots of each sliding part with means for fixing, preferably with means for clamping one in the Recording inserted profile section are provided. For this, e.g. through the side walls of the Recordings set screws are screwed, which are then from Processors as soon as the respective sliding part on the desired position relative to the support structure, are tightened and so the inserted profile sections pinch.

The support profiles can have different cross-sectional shapes have. So it is e.g. possible to support profiles with a T-shaped Cross section to use and the recordings to be arranged on the crossbar of the sliding part such that in the intended installation position of the sliding parts in each case a vertically downward profile section of the Cross-section T-shaped support profiles from above into the recordings can be introduced. In this way it is possible to First slide parts into a corresponding installation position on the respective balcony, terrace or the like. to put and then the support profiles from above onto the sliding parts sit up.

Alternatively, the support profiles can also be designed in this way be that on each of the two support profiles below the Each of the web part is an elongated, non-contacting part of the web part essentially horizontal profile section is provided, the elongated free Has edge to the opposite support profile, respectively then the two shots on the crosspiece of the Sliding part can be arranged that each one recording on one of the horizontal sections of the Support profiles can be pushed on.

The web part and the two support profiles can be integral be connected to each other, it is also possible To form the web part and support profiles in one piece. The web part and support profiles can be combined in one Manufacturing process in the extrusion process, or the support profiles can be folded by a originally flat web part are produced. there has such a design of the web part compared to the Formation of the web part as a separately produced grating different advantages. So the processor needs Cut a single part on site. The processing, but also processing, e.g. painting, designed overall easier. In addition, the production is cheaper realizable. Nevertheless, depending on the place of use not trained on well-known and proven gratings Can do without web parts. In this case it is then advantageous, support profiles with an F-shaped cross section with two mutually parallel profile sections and one to use vertical profile section, then when the drainage grate is installed as intended one of the two parallel profile sections of each support profile, the web part, that is Grating, carries while the other section section in one of the two recordings of a sliding part is inserted is. The support profiles are installed in such a way that their Cross-sectional shape to the shape of a rotated by 180 ° upside down F reminds.

Such a support profile with an F-shaped cross section can e.g. of two connected in a suitable manner L-shaped profiles can be composed, but it can also made from a single, multi-folded sheet metal his.

In a preferred embodiment of the invention the threaded receptacles provided on the crossbars of the sliding parts by means of threaded sleeves provided on the crossbars educated. Each crossbar can then be attached to the Place the threaded sleeves attached to the crossbar be pierced such that the threaded shafts of the the threaded sleeve, screwed feet through the crossbar can. Since the free ends of the threaded shafts Feet usually with one receptacle, e.g. a slit or a cross recess, for a corresponding screwdriver are provided, the feet can then also after Sliding on the support structure and inserting the Drainage grate in the for the drainage grate on the respective Balcony, terrace or the like intended inclusion by means of a corresponding tool can be adjusted, whereby of course the drainage openings provided in the web part one that allows the tool to be inserted Must be large.

The threaded sleeves can advantageously on the sliding parts be arranged that all threaded sleeves one Sliding part either on the web part of the drainage grate or to the floor of the balcony, the terrace or the like. looking Flat side of the crossbar are arranged, and that Web part can be designed such that it is both with to the web part as well as with threaded sleeves pointing to the bottom on the corresponding profile sections of the support profiles can be postponed and that each different Distances between the mouth closest to the ground each threaded sleeve and the bottom. To this Ways can be done by simply turning the sliding parts two different height adjustment ranges, within which one Height adjustment of the drainage grate by more or less feet can be screwed far into the threaded sleeves is to be realized.

1 is designated in its entirety by 10 Height-adjustable drainage grate in side view shown, in which a here formed by a grating 12 walkable web part of a two elongated, in Cross-section having F-shaped support profiles 14 and 16 Support structure is worn. The two support profiles 14 and 16 each have an upper horizontal profile section 18 or 20, the upper side of which is the grating 12 carries, and each a lower horizontal profile section 22 and 24 respectively, which are opposite to each other Long sides of the crossbar 26 one in its entirety recordings provided with 28 designated sliding part 30 and 32 are introduced.

The two elongated, F-shaped in cross section Support profiles 14 and 16 are over a number of cross braces 34, of which only one is visible here, with each other connected, each cross strut on the underside of the two upper horizontal profile sections 18 and 20 of the two support profiles and e.g. by riveting or welding to the profile sections connected is. Cross struts 34 and support profiles 14 and 16 thus form a stable support structure for the walkable Web part 12, which - as in the embodiment shown here - simply inserted into the support structure can be, the outer vertical portions of the two cross-sectionally F-shaped support profiles 14 and 16, respectively form a lateral guide for the web part 12, it can also be a before inserting the web part known dirt filter made of suitable material, e.g. a textile fleece.

The support structure itself is used by several on the Sliding part 28 provided and each a threaded shaft 36 feet 38 worn. To ensure the Height adjustment of the drainage grate 10 is each threaded shaft 36 in each one of the here as on the crosspiece 26th attached threaded sleeves 40 trained thread receptacles guided such that each foot 38 by simple rotation more or less approximated to the sliding part 28 can be. The sliding part 28 is in FIGS. 2 and 3 each seen in the direction of arrows 2 and 3 of FIG. 1 shown. It can be clearly seen that each of the opposite Provided long sides of the crossbar 26 Recordings 30 and 32 is formed in that by parallel Incisions 42 in the transverse web 26 formed profile strips 44 and 46 alternately upwards (profile strips 44) and bent downwards (profile strip 46) from the crosspiece 26 are, the free ends of the profile strips then again in a substantially parallel to the transverse web 26 Situation are bent back.

In this embodiment is in each profile strip 44 and 46 a threaded bore 50 is provided through which a screw not shown here, e.g. a grub screw, can be performed so that it becomes possible to slide the part 28 in a desired slide-open position relative to the support structure by tightening the screws and clamping the lower horizontal profile sections 22 and 24 to fix the cross-section F-shaped support profiles 14 and 16. The threads in the bores 50 can be used self-tapping screws are also eliminated. Note that by the relative to the longitudinal extent of the profile sections 22 and 24 parallel central axis of the crossbar 26 symmetrical formation of cross bar 26 and recordings 30 and 32 both pushed the sliding part can be that the threaded sleeves provided on the crossbar 40 - as shown in Fig. 1 - to the walkable web part 12 point out, as well as that the threaded sleeves 40 to Floor of the respective balcony, the terrace or the like. Clues, so that with a single web part two different Height adjustment ranges within which a height adjustment of the drainage grate by more or less wide Screwing in the threaded shafts 36 of the feet 40 is possible, can be realized.

Figure 4 shows those of the two F-shaped in cross section Support profiles 14 and 16 and these two support profiles connecting cross struts 34, of which here only one is visible, existing support structure and of an inserted grating 12 in a perspective view. The two F-shaped support profiles in cross section 14 and 16 are each in one piece in this embodiment by repeatedly folding an originally flat one elongated profile strip formed. in principle but it is also possible to have an F-shaped cross section To produce support profiles in one piece using the extrusion process, or each support profile from two L-shaped ones and e.g. connected by riveting or welding To form profiles. In any case, it is essential that each support profile 14 and 16 the respective walk-in Web part, so here the grating 12 supporting profile section 18 or 20 and a free profile section 22 or 24 has such that one on the free profile sections 22 and 24 pushed sliding part along these profile strips can be pushed into any desired position in which it then e.g. using the screws described is fixed.

The transverse struts 34 each have only a small width in the direction of the longitudinal extent of the support profiles 14 and 16, so that they have a plurality of drainage openings 52 (of which only a few have been provided with reference numerals for reasons of clarity) on the respectively inserted one. provided web part 12 do not hinder impinging moisture. In this embodiment, the cross struts 34 are connected to the horizontal profile sections 18 and 20 of the support profiles 14 and 16 by welding. In principle, however, it is also possible to screw the cross struts 34 to corresponding horizontal profile sections of the respective support profiles, so that an easy exchange of the respective cross struts for wider or narrower and thus also a wide adjustment of the support structure to the respective installation situation is possible, in which case, of course, sliding parts different widths must be provided.
FIG. 5 shows a possibility of constructing a walk-in web part 512 and support structure in one piece in a cost-effective manner in that, from an originally flat elongated perforated plate, the two support profiles 514 and 516 are folded on opposite longitudinal sides of the perforated plate, which enclose the web part 512 between them. The free ends of the two support profiles 514 and 516 are then folded again to form sliding guides for the receptacles of a corresponding sliding part, for example a sliding part 28 according to FIG. 1, in a position parallel to the walkable web part 512 such that the free ends of the horizontal profile sections 522 and 524 thus formed point to one another. This one-piece design of walkable web part 512 and support structure can - as mentioned - be done by folding over a perforated plate, that is, an already perforated plate; However, it is also possible to produce such a profile in the extrusion process and then to provide it with appropriate drainage openings or to punch drainage openings into an originally flat sheet metal blank and then to fold the metal blank several times in the manner described.

In Figure 6 is a support structure with a sliding part shown, the two support profiles 614 and 616 each have a T-shaped cross-section and over a number of cross struts 634, of which only one is visible here is connected. The cross struts 634 grip each on the underside of each support profile 614 and 616 provided horizontal profile section 618 and 620, the top of which is a support for one here walk-in part of the web, not shown, to be inserted, e.g. form a grating 12 according to FIG. 1. The two on opposite Ends of the crossbar 626 of the sliding part 628 provided recordings 630 and 632 are in this embodiment opened upwards in such a way that from the two T-shaped support profiles 614 and 616 and the cross struts 634 existing support structure from above in the corresponding recordings can be placed, whereby then a vertical profile section 622 and 624, respectively of the two cross-sectionally T-shaped support profiles 614 and 616 engages in one of the receptacles 630 and 632. The recordings are each from an inner profile strip 644 and an outer profile strip 646. In the inner and / or outer profile strips 644 and 646 can be tapped through which Screws for clamping the sliding part in a certain Position introduced relative to the support structure can be. On the side facing the cross strut 634 Top of the crossbar 626 of the sliding part 628 threaded sleeves 640 are again provided, in which corresponding ones Engage threaded shafts 636 of feet 640 which then more or less far into the threaded sleeves for height adjustment 640 can be turned.
