DE19616792C1 - Channel covering grid, particularly for swimpool overflow channels - Google Patents

Abstract

The grid is made of plastic and the individual profile bars are connected with two moulded-on, elastic expansion field components (2). The expansion field components are spaced away from the profile bar ends. The profile bars have hammer head profiles, with the head of the hammer head profile forming the surface of the channel covering grid. The upper side of the profile bar can be slightly rounded and is provided with grooves, which run at 90 degrees to each other and at 45 degrees to the profile bar longitudinal axis.

Description

Gutter cover grating made of plastic, especially for swimming pool flood gullies.

The invention relates to a channel cover grate according to the preamble of claim 1

Such a channel cover grate is from European patent application 0668410 A1 known. There, the profile bars forming the channel cover grate are connected a single, flexible rod, which with play through arranged in the middle of the profile bars Bores and through spacers located between the profile bars.

Due to the flexibility of the rod and the game mentioned, a curved course can be made of the gutter cover grate.

With this cover grate, each profile bar is around the rod arranged in the central axis rotatable.

Such rust is not stiff in itself

Proceeding from this, the object of the invention is to provide a gutter cover grating create that is stiff and still suitable for curved gutter profiles.

This object is achieved by the gutter cover grating specified in claim 1.

The stretch folding elements can be more or less because of their folded shape squeeze. The sum of the expansion gaps is so large that the individual Gutter cover grille shortened to approx. 75% of the length it has when relaxed can be.

By shortening only one long side of the channel cover grate, a curved one can be made Achieve gutter cover grating; gutter cover grids lined up next to each other can therefore be started adapt to different channels. Due to the expansion folding elements, the gutter cover grating according to the invention also easily absorb large thermal expansions. The channel cover gratings according to the invention are preferred for covering Flood channels used in swimming pools with overhead water levels.

The production takes place, as is usual with plastic cover gratings, in the injection molding process, so that the manufacturing effort is low.

The individual channel cover gratings can be connected to each other to any lengths. There are two vertical bolts on one end of the grate and on the the other face two vertical eyelets with the same diameter, like a hinge be plugged into each other.

Appropriate configurations of the gutter covering grate according to the invention are shown in FIGS Subclaims specified.

According to claim 2, the expansion fold elements are spaced from the profile bar ends arranged. As a result, the cast standard width of the gutter cover grate can Sawing the profile ends can be shortened to smaller widths without the connection of the individual profile bars is lifted one below the other.

The appropriate distance of the expansion folding element from the end of the profile rod has been approx. Proven 25mm.  

The formation of the profile bars with a hammer head cross section, according to claim 3, is advantageous because it creates the expansion element in the area of the tapered hammer handle has enough room to stretch.

According to claim 4, the top of the profile bar is slightly rounded and provided with grooves, which run at an angle of 90 ° to each other and to the longitudinal axis of the profile bar at less than 450. As a result, the accessible surface of the profile bars is designed so that it Safety regulations for slip resistance in the swimming pool area corresponds. In addition, the overflow water is prevented from running the channel longitudinally to the direction of the profile bar can cross.

Due to the configuration according to claim 5, the gutter cover grating hold on to forced curvature. This serves as additional security to one to counteract unintentional "straight lines" of curved gutter grids and to prevent the grate from accidentally jumping out of the channel.

The gutter cover grating according to the invention is described below using exemplary embodiments explained in more detail with reference to the drawing.

It shows:

Fig. 1 is a grates made of plastic as for swimming pools Überflutungsrinnen- cover with a straight course and in the relaxed state,

Fig. 2 is a view of the underside of the Rinnenabdeckrostes (curved course shortened single-sided),

Fig. 3 shows a cross section through the grates,

Fig. 4 is a longitudinal section through the channel cover grate with section A - A and a top view of the surface profile, and

Fig. 5 shows a grooved, flexible plastic rod.

A channel cover grate 1 consists of individual profile bars 3 , which are arranged at a parallel distance of approximately 8 mm upright from one another and transversely to the course of the channel. It is designed to cover an overflow channel in a swimming pool. The overflow water runs through the gaps between the profile bars into the channel. The serving the water inlet cross section of the free Rinnenabdeckrostes 1 should be as 40% of the total area of the grate 1, which is obtained from the bar width and bar spacing of no more than 8mm more.

The grate is made as a molded plastic part and is intended for the common channel widths from approx. 200mm to 500mm.

The length of the grate 1 is usually 0.3 m due to the tool.

It can be a maximum of 1m.

The grate thickness varies depending on the channel width and a point load of approx. 2 KN between 20mm and 35mm. The individual profile bars 3 are each connected to one another with two cast-on, elastic expansion folding elements 2 . Below the expansion folding element 2 there is a half-open, inwardly tapering bore 5 transverse to the longitudinal axis of the profile bar, into which a grooved, flexible plastic rod 5 can be clipped so that the forced curvature of the channel cover grating is retained.

So that the overflow water cannot cross the channel along the direction of the profile bar, the top of the profile bar 3 is slightly rounded and provided with grooves 6 , which are at a 90 ° angle to one another and at 45 ° to the longitudinal axis of the bar.

With this arrangement, both slip resistance and water blocking are achieved.
