Drain strainer for bathtub and shower traps with integrated shut-off valve and drain cover

Abstract

Drain strainer for bathtub or shower traps with integrated shut-off valve and drain cover, characterized in that the drain strainer is positioned on at least three legs in the trap, wherein the strainer plate is arranged so that it is located between the upper edge of the open shut-off valve and the lower edge of the drain cover without hindering its function

Description

1. Title of the invention: Drain strainer for bathtub and shower traps with integrated shut-off valve and drain cover. 2. Introduction

[0001] The present application relates to a technical product in the field of sanitary engineering, in particular a drain strainer for the siphons used in bathtubs and showers with integrated shut-off valve and drain cover. 3. State of the art

[0002] Currently, no suitable drain strainers are available for these specific siphon drains. Cleaning these drains is therefore time-consuming, as hair and other solids accumulate in the drainpipe and are difficult to remove. Strains are known to be either non-functional or difficult to handle, interfering with the operation of the shut-off valve or the replacement of the drain cover. 4. Technical Problem

[0003] The aim of the invention is to create a drain strainer that reliably retains solids while not impairing the function of the shut-off valve or the cover provided by the drain lid. Furthermore, the strainer should be easy to install and remove without tools or significant effort. 5. Solution to the problem / Description of the invention

[0004] The drain strainer ( Fig. According to the invention, the sieve plate (01) is inserted into the siphon (05) on three specially arranged legs (02a; 02b). The length (12) of the legs is dimensioned such that the sieve plate (01) is positioned between the upper edge of the open shut-off valve (06) and the lower edge of the drain cover (07) that covers the siphon. The diameter of the sieve plate is dimensioned such that the inner wall of the siphon rests almost completely against the sieve plate (04) to prevent unintentional flow of solids past it.

[0005] The legs are attached to the sieve plate (01) such that one leg (02a) of the sieve is located at the upper end of the sieve plate, while the other two legs (02b) are positioned behind the center of gravity and thus a short distance behind the central axis (10) of the sieve plate. This ensures that the sieve remains stable in a horizontal position after insertion.

[0006] To remove the drain strainer, press on the side without the leg (11), whereupon the opposite side of the strainer tilts upwards, allowing for easy removal.

[0007] All legs are rubberized (03) to prevent scratches on the siphon and to ensure a secure stand. 6. Advantages of the invention • Effective retention of hair and solid particles • The function of the siphon (05), the shut-off valve (06) and the drain cover (07) is still ensured. • Quick and easy cleaning thanks to easy removal without tools • Protection and stability thanks to rubberized legs (03) • Optimal fit for secure hold and maximum functionality 7.

Claims

[1] Drain strainer for bathtub or shower traps with integrated shut-off valve and drain cover, characterized by that the drain strainer is positioned on at least three legs in the siphon, the strainer plate being arranged so that it is located between the top edge of the open shut-off valve and the bottom edge of the drain cover without hindering its function [2] Drain strainer according to claim 1, characterized by , that the diameter of the sieve plate is dimensioned so that an almost gapless connection to the inner wall of the siphon is achieved, thereby preventing the flow of solids past it. [3] Drain strainer according to claim 1 or 2, characterized by , that the three legs are arranged such that one leg is positioned at the top of the sieve plate and the other two are positioned behind the center of gravity of the drain sieve, thus holding the sieve in a horizontal position by gravity. [4] Drain strainer according to any one of the preceding claims, characterized by , that by applying pressure to the side of the sieve plate without a leg, the opposite side tilts upwards, allowing easy removal of the sieve. [5] Drain strainer according to any one of the preceding claims, characterized by , that the legs are rubberized to prevent damage to the siphon and to increase stability.
