Abstract
The present sliding security door system includes a sliding security door extending between an upper track and a lower track. Separate motive and locking assemblies drive and secure the door, respectively. A control assembly in the system is capable of separately activating motive and locking effectors to allow for separate movement and locking/unlocking of the door. Because of this, the system is compact and capable of deployment in otherwise too-small spaces.
Claims18
A sliding security door system comprising:
- a door extending between an upper track and a lower track;
- a motive assembly located in the upper track for driving a carriage assembly connected to the door, wherein the motive assembly comprises a motive effector operably connected to a rack connected to a carriage;
- a locking assembly at least partially located in the upper track for preventing movement of the door, wherein the locking assembly comprises a locking effector operably connected to a locking bar;
- a control assembly operably connected to the motive assembly and the locking assembly, wherein the control assembly is capable of separately activating the motive effector and the locking effector;
- and
- a lateral fire seal assembly comprising a seal plate connected to a wedge lock, wherein at least one vertical fire seal is connected to the wedge lock opposite the seal plate.
