Abstract
The present disclosure describes various embodiments of a concealed or hidden door closer that is installed in a rail of a door assembly. In some embodiments, the door frame and door closer components are configured to allow the door assembly to be readily installed as either a left or a right hand hinged door.
Claims22
A door assembly, comprising:
- a door having vertical latch and hinge stiles attached to upper and lower horizontal rails, the upper horizontal rail having (i) one closer pocket adjacent to the vertical hinge stile, (ii) one closer pocket in a center region of the upper horizontal rail, or (iii) two closer pockets located in regions of the upper horizontal rail adjacent to the vertical latch and hinge stiles, or the lower horizontal rail having (i) one closer pocket adjacent to a vertical hinge stile, or (ii) one closer pocket in a center region of the lower horizontal rail;
- a drip cap connectable to a door opening above the upper horizontal rail having a horizontal body with first and second ends and comprising a slide track within the horizontal body of the drip cap extending from the first end to the second end of the drip cap, wherein the drip cap remains stationary when the door is opened or closed;
- a slide fixture insertable into the slide track and movable between the first and second ends of the horizontal body of the connectable drip cap;
- a closer insertable into one of the closer pockets comprising a closer body attached to the horizontal rail, and a pinion rotatably connected to an internal biasing mechanism and having at least one connecting stud extending through the closer body, wherein the pinion provides sufficient rotational force to move the door from an opened position to a closed position;
- and
- a closer arm having an attachment fixture on one end of the closer arm attachable to the pinion connecting stud and an opposite end of the closer arm attachable to the slide fixture.

A door assembly kit comprising:
- a door having vertical latch and hinge stiles attached to upper and lower horizontal rails, the upper horizontal rail having (i) one closer pocket adjacent to the vertical hinge stile, (ii) one closer pocket in a center region of the upper horizontal rail, or (iii) two closer pockets located in regions of the upper horizontal rail adjacent to the vertical latch and hinge stiles, or the lower horizontal rail having (i) one closer pocket adjacent to the vertical hinge stile, or (ii) one closer pocket in a center region of the lower horizontal rail;
- a drip cap connectable to a door opening above the upper horizontal rail having a horizontal body with first and second ends and comprising a slide track within the horizontal body of the drip cap extending from the first end to the second end of the drip cap, wherein the drip cap remains stationary when the door is opened or closed;
- a slide fixture insertable into the slide track and movable between the first and second ends of the horizontal body of the connectable drip cap
- a closer insertable into one of the pockets of the horizontal rails comprising a closer body attached to the horizontal rail, and a pinion rotatably connected to an internal biasing mechanism and having at least one connecting stud extending through the closer body, wherein the pinion provides sufficient rotational force to move the door from an opened position to a closed position;
- a closer arm having an attachment fixture on one end of the closer arm attached to the pinion connecting stud and an opposite end of the closer arm attachable to the slide fixture;
- a latch mechanism having latching components attachable to at least one of the vertical stiles in either an internal or an external configuration;
- a vertical latch frame;
- and
- a vertical hinge frame attachable to at least one of the vertical stiles to provide either a left or right hinged door.
