A portable door securement device is provided having a member extending from a first end engaged to a doorknob of a door to a second end engaged with a floor adjacent the door, to prevent opening of the door in a direction toward the engaged member. A slot at a first end of the member engages around a stem of the door handle thereby preventing disengagement of the member from the door, and preventing opening of the door.

The present invention is a positioning mechanism device to prevent the motion of one surface with respect to a second surface, in one direction. The positioning mechanism uses a linear adjusting lock, an actuator, and an over-ride mechanism. The linear adjusting lock uses a coil spring to hold a rod in place. When firmly coiled, the coil spring is able to grip a smooth rod and prevent axial motion. When the coil spring is uncoiled, slightly, it releases its grip on the smooth rod, allowing axial motion. The positioner mechanism uses an actuator and release blade to release the coil spring. Additionally, the over-ride mechanism can be used to release the release blade in one direction without use of the actuator. When the coil spring is released by either the actuator or over-ride mechanism the two surfaces can be re-positioned relative to one another.

A lock assembly is provided for a window having a first sash and a second sash. The lock assembly comprises an elongate strip configured to be coupled to the first sash. The elongate strip has a plurality of recesses defined along a length of the elongate strip. The lock assembly also includes a lock member configured to be coupled to the second sash and operable to move along the length of the elongate strip. The lock member includes a biasing member and a coupler biased in a direction of the elongate strip by the biasing member. The coupler is configured to enter each of the plurality of recesses to selectively lock the lock member to the elongate strip.

An aircraft door latch arm rotation limiting device incorporates a flexible strap having a proximal end and distal end. The distal end is insertable through a loop eye proximate to an aircraft door. An elongate sleeve is disposed on the proximal end of the flexible strap and the sleeve is received over a rotatable latch arm of an aircraft door. A first receiving element intermediate the proximal and distal ends of the flexible strap releasably engages the distal end of the flexible strap to establish a first predetermined looped strap length restricting rotation of the lever beyond a partially open position. A second receiving element is disposed between the first receiving element and the proximal end on the flexible strap to releasably engage the distal end to establish a second predetermined looped strap length preventing rotation of the lever from a closed position.

A device for restricting movement of a door includes a door member, a floor member, and a connecting member. The door member is fixedly mounted to a door and includes a first opening having a first predetermined shape. The floor member is fixedly mounted to a floor and includes a second opening having a second predetermined shape. The connecting member includes a first leg and a second leg. The first leg extends in a first direction and has a first end removeably engaging the first opening. The second leg extends in a second direction that is perpendicular to the first direction and has a second end removeably engaging the second opening simultaneously when the first end removeably engages the first opening thereby preventing rotation of the door.

The invention relates to a motor vehicle lock comprising a locking mechanism provided with a rotary latch and at least one pawl, a rotary movement of the rotary latch can be blocked by means of the pawl, a drive device by means of which the pawl can be transferred from the locked position into a release position for the locking mechanism, and an adjusting device (9). A motor vehicle part (4) accommodating the vehicle lock can be moved from the closed position into an open position by means of the adjusting device (9). Said adjusting device (9) maintains the motor vehicle part (4) in the open position such that the motor vehicle part (4) can be prevented from opening automatically from the open position.
