Abstract
A ligature resistant strainer for a drain assembly and connecting to a drain system. The strainer includes a grate and an extension block coupled to the grate. The grate defines a first thickness, and the extension block defines a second thickness that is greater than the first thickness. Portions of the grate cooperate with portions of the extension block to define a plurality of apertures extending through the strainer and inhibiting attachment of a ligature to the strainer.
Claims23
A ligature resistant strainer for a drain assembly and connecting to a drain system, the strainer comprising:
- a grate, the grate defining a first thickness;
- an extension block coupled to the grate, the extension block defining a second thickness, the second thickness being greater than the first thickness;
- portions of the grate and portions of the extension block cooperating to define a plurality of apertures, the plurality of apertures extending through both the first thickness of the grate and the second thickness of the extension block;
- and
- a retainer mechanism configured to retainingly engage the strainer in the drain assembly, the retainer mechanism being supported by the grate and independent of the extension block.
A ligature resistant drain assembly for connecting to a drain system, the drain assembly comprising:
- a drain body having outlet coupling adapted for connecting to the drain system;
- and
- a strainer coupled to the drain body, the strainer including a grate having a first thickness, portions of the grate defining a plurality of apertures extending through the grate, the strainer further including an extension block extending from the grate and having a second thickness, the second thickness being greater than the first thickness, the extension block including portions defining a plurality of apertures extending through the extension block, the apertures of the extension block corresponding to the apertures of the strainer and defining cooperatively defining extended apertures extending through the strainer, and
- a retainer mechanism configured to retainingly engage the strainer in the drain body, the retainer mechanism being supported by the grate and independent of the extension block.
A ligature resistant shower pan assembly for connecting to a drain system, the shower pan assembly comprising:
- a shower pan defining a basin, portions of the basin defining a drain opening extending through the basin;
- a drain body having outlet coupling configured to connect to the drain system;
- a collar attached to the drain body and cooperating with the drain body to engage the shower pan between the collar and the drain body;
- a strainer coupled to the drain body and including a grate and an extension block extending from the grate, the grate having a first thickness and an extension block having a second thickness, the second thickness, the second thickness being greater than the first thickness, portions of the grate and portions of the extension block cooperatively defining a plurality of apertures extending through the strainer, the grate and the extension block being one of individual components connected to each another or a one-piece construction;
- and
- a retainer mechanism supported by the grate and being independent of the extension block, the retainer mechanism being configured to retainingly engage the strainer with the drain body, the retainer mechanism including a member moveable between a radially inward position and a radially outward position, in the radially outward position the member engaging the drain body.
