Abstract
A system for interlocking and unlocking a sliding door includes a handle, attachable flush-mountably to the sliding door. The handle has an electro-mechanical locking mechanism attachable in a wall-mount manner, and having a movable locking element movable between a protracted locking position and a retracted releasing position, and an electronic drive, incorporated into the locking mechanism and in operative connection with the locking element. The handle is manually movable between an opening position and a closing position, the handle and the locking mechanism cooperate such that, in the locking position of the locking element and in the closing position of the handle, movement of the sliding door from a closed location in the direction of an opening location can be blocked and, in the opening position of the handle, movement of the sliding door can be effected from the closed location in the direction of the opening location.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
