curtains A47H; lids for car boots or bonnets B62D25/10; skylights E04B7/18; sunshades, awnings E04F10/00) ## Abstract An entry door drainable threshold comprises a front section including one or more water egress apertures; a trough section including one or more apertures; and a water ramp member disposed under the trough section and the front section, whereby water falls down through the one or more apertures of the trough section, down the water ramp member, and out of the entry door drainable threshold through the one or more water egress apertures. ## Claims ### Claim 1 A drainable threshold, comprising: a front section including one or more water egress apertures; a trough section including a plurality of elongated T-shaped members and a plurality of recesses each formed in part by and between the elongated T-shaped members, the plurality of recesses including a plurality of apertures; and a water ramp member disposed under the trough section and the front section, whereby water falls down through the plurality of apertures of the plurality of recesses of the trough section, down the water ramp member, and out of the drainable threshold through the one or more water egress apertures, wherein the drainable threshold is configured to be used in one or more of a commercial application, an industrial application, a warehousing application, and a loading application. ### Claim 2 (depends on 1) The drainable threshold of claim 1, wherein the drainable threshold has a two-piece construction comprised of a threshold ramp and a threshold cap. ### Claim 3 (depends on 1) The drainable threshold of claim 1, wherein the drainable threshold includes an anti-skid profile. ### Claim 4 (depends on 3) The drainable threshold of claim 3, wherein the anti-skid profile includes one or more of ridges and bumps. ### Claim 5 (depends on 1) The drainable threshold of claim 1, wherein the drainable threshold includes a drainage flow rate of at least 2.3 gallons per minute per 3 foot section. ### Claim 6 (depends on 1) The drainable threshold of claim 1, wherein the front section includes an inclined upper surface and a horizontal upper surface. ### Claim 7 (depends on 1) The drainable threshold of claim 1, wherein the water ramp member includes an upper end and the trough section is disposed above the upper end of the water ramp member. ### Claim 8 (depends on 1) The drainable threshold of claim 1, wherein the drainable threshold is for a roll-up door. ### Claim 9 (depends on 1) The drainable threshold of claim 1, wherein apertures of the plurality of apertures of the trough section are aligned with the one or more water egress apertures of the front section. ### Claim 10 (depends on 1) The drainable threshold of claim 1, wherein the plurality of apertures of the trough section and the one or more water egress apertures of the front section are slots. ### Claim 11 (depends on 1) The drainable threshold of claim 1, further including a rear section. ### Claim 12 (depends on 11) The drainable threshold of claim 11, wherein the rear section includes an inclined upper surface and a horizontal upper surface with elongated ridges. ### Claim 13 (depends on 12) The drainable threshold of claim 12, wherein the rear section includes a rear having a rear supporting section with a flat undersurface that rests on underlying floor. ### Claim 14 (depends on 12) The drainable threshold of claim 12, wherein the drainable threshold has a two-piece construction including a threshold ramp and a threshold cap that together include the front section, trough section, and the water ramp member, the horizontal upper surface includes an underside having a downwardly extending vertical ridge and a downwardly extending rear wall that form an elongated receiving recess and the water ramp member includes an upper portion received in the elongated receiving recess to secure the threshold ramp and the threshold cap together. ### Claim 15 (depends on 14) The drainable threshold of claim 14, wherein the threshold ramp includes an elongated base flange that rests on an underlying floor. ### Claim 16 (depends on 1) The drainable threshold of claim 1, wherein the threshold has a height no greater than ½ in. ### Claim 17 (depends on 1) The drainable threshold of claim 1, wherein the threshold is made of extruded aluminum. ### Claim 18 (depends on 1) A method of using the drainable threshold of claim 1, comprising: receiving water through the plurality of apertures of the trough section; draining the water down the water ramp member; emitting the water out of the drainable threshold through the one or more water egress apertures. ### Claim 19 A drainable threshold, comprising: a front section including one or more water egress apertures; a trough section including a plurality of recesses with a bottom having a plurality of apertures; and a water ramp member disposed under and spaced from the bottom of the plurality of recesses of the trough section, whereby water falls down through the plurality of apertures of the trough section, down the water ramp member, and out of the drainable threshold through the one or more water egress apertures, wherein the drainable threshold is configured to be used in one or more of a commercial application, an industrial application, a warehousing application, and a loading application. ### Claim 20 (depends on 19) The drainable threshold of claim 19, wherein apertures of the plurality of apertures of the trough section are aligned with one or more water egress apertures of the front section. ### Claim 21 (depends on 19) The drainable threshold of claim 19, wherein apertures of successive recesses of the plurality of recesses being staggered relative to each other so that the apertures of successive recesses are not aligned with each other.
