Door handle lock

A lock for a door lever handle, the lock comprising:

• a base configured to mount the lock to a door having a lever handle;
• and
• a lever handle guard pivotally attached to the base, the lever handle guard being pivotable between a locking position and a non-locking position, wherein the lever handle guard is securable in the non-locking position, the lever handle guard comprising:
• a first guard portion arranged to prevent rotation of the lever handle beyond a first rotation angle in a first direction when the lever handle guard is in the locking position;
• and
• a second guard portion arranged to prevent rotation of the lever handle beyond a second rotation angle in a second direction when the lever handle guard is in the locking position, the second direction being opposite to the first direction;
• wherein, when the lever handle guard is secured in the non-locking position, the first and second guard portions are arranged to permit rotation of the lever handle in the first and second rotation directions beyond the first and second rotation angles without contacting the first and second guard portions;
• wherein the first and second guard portions are connected to one another;
• and
• wherein the lever handle guard is constructed and arranged such that movement of the first and second guard portions toward one another allows the lever handle guard to pivot from the locking position to the non-locking position.

A combination of a lock, a door lever handle, and a latch where the lever handle is rotatable to release the latch from a doorframe, the combination comprising:

• a lock comprising:
• a base configured to mount the lock to a door having a lever handle and a latch, wherein the lever handle is rotatable to release the latch from a doorframe;
• a lever handle guard pivotally attached to the base to rotate around a vertical pivot axis, the lever handle guard being pivotable between a locking position and a non-locking position around the vertical pivot axis;
• wherein when the lever handle guard is secured in the non-locking position the handle guard permits sufficient rotation of the lever handle to pull back the latch and release the latch from the doorframe, and wherein when the lever handle guard is secured in the non-locking position, the lever handle guard is not pivotable by a sufficient amount to pull back the latch and release the latch from the doorframe.

A lock for a door lever handle, the lock comprising:

• a base configured to be mounted to a door;
• a lever handle guard attached to the base, the lever handle guard being movable between a locking position and a non-locking position, the lever handle guard including:
• a first guard portion arranged to prevent rotation of the lever handle beyond a first rotation angle in a first direction when the lever handle guard is in the locking position;
• a second guard portion arranged to prevent rotation of the lever handle beyond a second rotation angle in a second direction when the lever handle guard is in the locking position, the second direction being opposite to the first direction;
• wherein:
• the lever handle guard is securable in the locking position;
• and
• the lever handle guard is constructed and arranged such that movement of the first guard portion closer to the second guard portion unsecures the lever handle guard from the locking position.

A lock for a door lever handle, the lock comprising:

• a base configured to mount the lock to a door having a lever handle which rotates a spindle;
• a lever handle guard pivotally attached to the base, the lever handle guard being pivotable between a locking position and a non-locking position, wherein the lever handle guard is configured to be secured in the locking position, and the lever handle guard extends substantially perpendicular to the base when the lever handle guard is secured in the locking position, the lever handle guard comprising:
• a first guard portion arranged to prevent rotation of the lever handle beyond a first rotation angle in a first direction when the lever handle guard is in the locking position;
• a second guard portion arranged to prevent rotation of the lever handle beyond a second rotation angle in a second direction when the lever handle guard is in the locking position, the second direction being opposite to the first direction;
• and
• a blocker positioned to prevent movement of the lever handle guard from the non-locking position to the locking position;
• wherein the first guard portion pivots about a pivot axis to move from the non-locking position to the locking position, and the pivot axis and the first guard portion are arranged such that when the lock is mounted to a door having a door lever handle which rotates a spindle, the pivot axis and the first guard portion are positioned on a same side of the spindle;
• wherein, when the lever handle guard is in the non-locking position, the first guard portion is arranged to permit rotation of the lever handle in the first rotation direction beyond the first rotation angle without the lever handle contacting the first guard portion, and the second guard portion is arranged to permit rotation of the lever handle in the second rotation direction beyond the second rotation angle without the lever handle contacting the second guard portion.

A lock for a door lever handle, the lock comprising:

• a base configured to mount the lock to a door having a lever handle;
• a lever handle guard pivotally attached to the base, the lever handle guard being pivotable between a locking position and a non-locking position, the lever handle guard comprising:
• a first guard portion arranged to prevent rotation of the lever handle beyond a first rotation angle in a first direction when the lever handle guard is in the locking position;
• a second guard portion arranged to prevent rotation of the lever handle beyond a second rotation angle in a second direction when the lever handle guard is in the locking position, the second direction being opposite to the first direction;
• and
• a first blocker positioned to prevent movement of the lever handle guard from the non-locking position to the locking position, wherein the first blocker is positioned to prevent movement of the lever handle guard from the locking position to the non-locking position;
• wherein, when the lever handle guard is secured in the non-locking position, the first and second guard portions are arranged to permit rotation of the lever handle in the first and second rotation directions beyond the first and second rotation angles without any portion of the lever handle contacting the first guard portion when the lever handle is rotated in the first direction and without any portion of the lever handle contacting the second guard portion when the lever handle is rotated in the second direction.
