Device for protecting fingers from doorway injuries
A device for protecting the fingers of a person from getting impinged in between the door and the doorframe during closing of the door by an operator is provided. The device includes a gripping body configured to wrap around the shank of the doorknob, a bumper body attached to the gripping body configured to prevent the closing of the door, a hollow unit positioned between the bumper body and the gripping body, and one or more connecting body to pass through the hollow unit to connect the gripping body with the shank of the doorknob. When the door is opened, the bumper body is positioned between the door and the door frame. In order to close the door, the operator rotates the doorknob normally, which moves the bumper body, away from the leading edge of the door. The process makes an operator cautious while closing the door and thus effectively protects fingers and hands of the person from injuries that may result from a slamming door.

BRAKING DEVICE FOR A MOVABLE DOOR LEAF AND A DOOR CLOSER HAVING SUCH A BRAKING DEVICE
A braking device for a moveable door leaf comprises an electrical brake motor being operated as a generator, the motor shaft of which is rotatable by a movement of the door leaf and which can be controlled for regulating the closing speed of the door leaf by means of an electronic evaluation and control unit, which is at least partially providable with electrical energy by an electric motor being operated as a generator, particularly the brake motor, and/or by means of an additional generator unit. The electronic evaluation and control unit is thus operable in a sleep mode and is cyclically displaceable into a waking state depending on the closing speed of the door leaf, wherein the wake-up frequency with which the electronic evaluation and control unit is cyclically awakened during a respective closing movement of the door leaf is less at relatively lower closing speeds of the door leaf than at relatively greater closing speeds of the door leaf. A door closer with a mechanical energy storage and a correspondingly designed braking device is also disclosed.

Safety door lock using door handle
A safety door lock may include the door handle configured to be rotatable about a rotational axis and to slidably reciprocate in a horizontal direction and having a sliding groove on the side surface thereof adjacent to a door. The safety door lock may include a body combined with an inside of the sliding groove to form a rotating shaft with another door handle provided at the other side of the door and supporting sliding of the door handle so as to protrude the door handle from the front end of the door. The safety door lock may include an elastic unit fixed to the body, and elastically relaxing the door handle and the body. Other embodiments may also be provided.

Hinged surface chock deployment and stowage enabling apparatus and method
A mechanism or apparatus enables stowing a hinged surface chock at a stowage position near a deployment position. Said stowage and deployment positions separated by a gap between a first hinged surface and a second hinged surface, where said hinged surfaces are attached by at least one hinge. The apparatus enables the transition of said chock through said gap when one of said hinged surfaces is sufficiently open. Said apparatus will enable stowing said chock by holding said chock at the side of the gap where said chock does not obstruct the closing path of either hinged surface and said apparatus will enable deploying said chock by holding said chock where, at least partially, said chock obstructs the closing path of at least one of said hinged surfaces. Said apparatus may further enable arranging said chock at a wider angle at the deployed position.
Rotary door stop
The present disclosure provides a rotary door stop. The rotary door stop includes a door stop rotation base and a door stop body. The door stop body rotates about the door stop rotation base to define a locked state or an unlocked state. By engagement between a first limiting portion and a second limiting portion, the rotary door stop is retained in the locked state for ease of door closing; and when the rotary door stop approaches a door frame, retention of the unlocked state may also be released while the door is closed.

Closure member stop and associated kit
A closure member (e.g., door) stop includes a base having a top portion opposite a bottom portion, the bottom portion being configured for affixing to an installation point associated with the closure member, a flexure extending away from the top portion, a cushion comprising an angled face and an impact face, the impact face being configured to interface with the closure member during closing of the closure member, and the angled face being configured to interface with the closure member during opening of the closure member. The flexure provides an operable, bendable connection between the cushion and the base. Also, a lever is operably connected to the cushion and the flexure and configured to move the cushion away from a swing path of the closure member. The cushion extends into a swing path of the closure member when the closure member stop is at rest in the installed position.
