Abstract

A door system comprises a door, the door including a latch assembly configured to latch the door to a door frame to maintain the door in a closed position and to unlatch to allow the door to open to an opened position. A foot pedal is operatively connected to unlatch the latch assembly upon actuation by a user's foot. In certain embodiments, a handle can be operatively connected to unlatch the latch assembly upon actuation a user. The door system further includes the door frame and set of hinges operatively connecting the door to the door frame.

Claims (31)

1. A door system comprising:

a door including a latch assembly configured to latch the door to a door frame to maintain the door in a closed position and to unlatch to allow the door to open to an opened position;

a foot pedal operatively connected to unlatch the latch assembly upon actuation by a user's foot, wherein the latch assembly includes a pair of latch members at opposed ends of the door, wherein each latch member is operatively connected to a rack, the rack including an upper rack and a lower rack, wherein each rack is configured to move parallel to a hinge line, and wherein each rack is meshed with a pinion gear for synchronized actuation of each latch member; and

at least one removable access panel on the door positioned for at least one of: servicing the latch assembly or a rack and gear assembly, or for an emergency opening of the door.

2. The door system as recited in claim 1 , further comprising:

the door frame; and

set of hinges operatively connecting the door to the door frame.

3. The door system as recited in claim 2 , further comprising at least one helical spring disposed on the set of hinges, and a gas spring operatively connected between the door and the door frame, wherein the at least one helical spring and the gas spring are configured to exert a resultant spring force on the door to open the door in the unlatched position.

4. The door as recited in claim 1 , wherein the door includes a pair of door panels hingedly connected to one another along the hinge line.

5. The door system as recited in claim 4 , wherein the latch assembly actuates in a direction into and out of the door, parallel to the hinge line.

6. The door system as recited in claim 1 , further comprising a linkage operatively connecting the foot pedal to the pinion gear.

7. The door system as recited in claim 1 , wherein the latch assembly further comprises a compression spring disposed around each latch member between the rack and a tip of each latch member configured to bias each latch member in a latched position.

8. The door system as recited in claim 1 , wherein the foot pedal is a first foot pedal, and further including a second foot pedal, wherein the first foot pedal is an exterior foot pedal, wherein the second foot pedal is an interior foot pedal.

9. The door system as recited in claim 8 , wherein the first and second foot pedals are foldably connected to a linkage, wherein the first and second foot pedals are configured to move between a folded position and an unfolded position.

10. The door system as recited in claim 9 , wherein in the folded position, actuation of the latch assembly is prohibited and wherein in the unfolded position, actuation of the latch assembly is permitted.

11. The door system as recited in claim 8 , wherein the first and second foot pedals are foldably connected to a linkage, wherein the first and second foot pedals are configured to move between a folded position and an unfolded position, wherein in the folded position actuation of the latch assembly is prohibited, and wherein in the unfolded position actuation of the latch assembly is permitted.

12. The door system as recited in claim 1 , further comprising a foot actuated door lock disposed on an interior surface of the door slidable between a locked position and an unlocked position, wherein the locked position restricts movement of the foot pedal and wherein the unlocked position permits movement of the foot pedal.

13. The door system as recited in claim 1 , further comprising a handle operatively connected to unlatch the latch assembly upon actuation by a user.

14. The door system as recited in claim 1 , further comprising a foot actuated door lock disposed on an interior surface of the door slidable between a locked position and an unlocked position, wherein the locked position restricts movement of the foot pedal and wherein the unlocked position permits movement of the foot pedal.

15. The door system as recited in claim 1 , further comprising a handle operatively connected to unlatch the latch assembly upon actuation by a user and at least one removable access panel on the door positioned for at least one of: servicing the latch assembly or a rack and gear assembly, or for an emergency opening of the door.

16. A door system comprising:

a door frame;

a door including a latch assembly configured to latch the door to the door frame to maintain the door in a closed position and to unlatch to allow the door to open to an opened position;

a set of hinges operatively connecting the door to the door frame;

at least one helical spring disposed on the set of hinges;

a gas spring operatively connected between the door and the door frame; and

a foot pedal operatively connected to unlatch the latch assembly upon actuation by a user's foot, wherein the latch assembly includes a pair of latch members at opposed ends of the door, wherein each latch member is operatively connected to a rack, the rack including an upper rack and a lower rack, wherein each rack is configured to move parallel to a hinge line, wherein each rack is meshed with a pinion gear for synchronized actuation of each latch member, and wherein the at least one helical spring and the gas spring are configured to exert a resultant spring force on the door to open the door in the unlatched position.

17. The door as recited in claim 16 , wherein the door includes a pair of door panels hingedly connected to one another along the hinge line, wherein the latch assembly actuates in a direction into and out of the door, parallel to the hinge line.

18. The door system as recited in claim 16 , further comprising a linkage operatively connecting the foot pedal to the pinion gear.

19. The door system as recited in claim 16 , wherein the latch assembly further comprises a compression spring disposed around each latch member between the rack and a tip of each latch member configured to bias each latch member in a latched position.

20. The door system as recited in claim 16 , wherein the foot pedal is a first foot pedal, and further including a second foot pedal, wherein the first foot pedal is an exterior foot pedal, wherein the second foot pedal is an interior foot pedal.
