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.

An assembly according to some embodiments of the disclosure includes an enclosure having a housing and door hingedly attached to the housing and a door stop mechanism which holds the door in an open position. The mechanism includes a link member pivotally connected to the door and to the housing. The link member has an elongated slot which extends along a portion of the link member. The slot has a linear portion and an enlarged opening at an end thereof which is offset from the linear portion. When the door is opened, a fastener, which is either mounted to the housing or to the door, slides along the slot until the fastener is positioned in the enlarged opening to hold the door open.

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.

A method of operating a window having a sash and a window opening limit device includes moving the sash from a closed position to a limited position. When in the limited position, the window opening limit device is in a projected position, and the sash is engaged with the window opening limit device. Moving the window opening limit device to a retracted position disengages the sash and the window opening limit device. The sash may then be moved from the limited position to an open range. When the sash is returned to the closed position, the window opening limit device automatically returns to the projected position, and the sash is disengaged with the window opening limit device.

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.

Embodiments discussed herein enable an authorized user of a door security device to secure a door against entry, but also enable that authorized user to provide access to others, without having to provide a physical key. Embodiments discussed herein further allow an authorized user to operate the door security device remotely, such as through a wired or wireless network, or through any other network as described herein, as known at the time of filing, and/or as developed after the time of filing.

A portable door securement device is provided having a member extending from a first end engaged to a doorknob of a swinging door or endwall of a sliding door. A second end of the securement device is configured to be engaged with a support surface adjacent the door, to prevent opening of the door in a direction toward the engaged member.

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 door barricade having a pivoting locking arm which drops into a floor hole to lock a barricade in place.

A door security system is provided which is used to prevent a door, which separates first and second spaces, from opening. The door security system includes a security apparatus which is configured to be engaged with the floor within a first space. If the door is to be opened into the first space, the security apparatus blocks the door from opening into the first space. If the door is to be opened into the second space, an attachment assembly of the door security system acts in concert with the attachment assembly to block the door from opening into the second space. The door security system further includes a release mechanism which can be manipulated from the second space to disengage the security apparatus within the first space, thereby allowing for the door to be opened into either the first or second spaces, as appropriate.
