The aim of the invention is to achieve a door closer arrangement (1) where the force needed for opening the door (2) is not so substantial. The invention comprises a door closer (6), a slide rail (7), and an arm (8) that connects the door closer with the slide rail. The arrangement comprises also a second rail (9), which is arranged to form a slide slope for the door closer (6).

A hold-open latch structure for opposite sliding doors for a vehicle includes a roller mechanism swing arm which rotates about a rotating shaft formed in a roller mechanism at the time of opening or closing the door, and moves the door toward the inside and outside of the vehicle and in a longitudinal direction of the vehicle. A locking unit enables the door to be opened or closed and maintains an opened state of the door. The locking unit further includes a catch pivotably mounted on the rotating shaft and coupled to the roller mechanism swing arm so as to rotate together with the roller mechanism swing arm at the time of opening or closing the door. A lever is mounted so that one side of the lever is in contact with the catch.

A retention assembly may comprise a motor assembly and a self-locking worm drive coupled thereto. A cam may be fixed to a worm gear of the worm drive. The retention assembly may further comprise an actuation shaft including a follower. The actuation shaft may be displaceable over a displacement range via rotation of the cam. The retention assembly may further comprise a securement member with a securement member follower, the securement member coupled to a portion of the actuator shaft. The retention assembly may further comprise a housing cam included as part of the retention assembly housing and against which the securement member follower may be biased. The securement member may be in an open state when the actuation shaft is in a first position. The securement member may swing outward to a retaining position as the actuation shaft is moved to a second position.

Disclosed is a silent, soft-close compact hinge comprising of a hinge cup pivotally connected to a hinge body via a hinge arm. A set of coil springs biases the hinge to a closed position. A damping mechanism is removably attached to the hinge cup and acted on by the hinge arm. A set of spring sleeves are fitted to the coil springs to insulate the movement of the coil springs on the hinge arm providing the closing bias. The hinge body is comprised of three separate plates adjustably connected to each other with cam screws. The position of the hinge body with respect to the hinge arm is adjustable in three directions without the need for removal or loosening of mounting hardware used to attach the hinge body to a furniture piece.

A counterbalance assembly for an appliance has a guide member with a rotatable pulley with a fixed radius and a cam affixed to one side of the pulley and having a varying radius. The cam and the pulley rotate about a pulley axis of rotation as a single unit. The counterbalance has a force applicator that applies a counterbalance force to one of the pulley or cam, and the counterbalance has a connector that couples the other of the pulley or cam to the door. The counterbalance force applies a varying counterbalance torque to the door that is a function of the ratio between the fixed radius and the varying radius over the pivotal range of the door.

A transmission mechanism applied to a lock and for controlling the lock to switch between an unlocked state and a locked state. The lock includes a first handle set including a first cover plate which includes a first fitting portion. The transmission mechanism includes a transmission element and a moving component. The transmission element is connected to the first handle set in a manner that the transmission element is incapable of moving along a rotating axis and has an abutting portion. The moving component is disposed on the transmission element in a manner that the moving component is capable of moving along the rotating axis and includes a first engaging groove, a second engaging groove and a second fitting portion. When the transmission element is operated to rotate, the abutting portion is capable of switching between the first engaging groove and the second engaging groove.

A carriage has a wing part which can be fastened to a wing and a roller part which is displaceable on a running rail. The wing part is displaceable in a positively controlled manner transversely to the running rail. The roller part has a height-adjustable roller upper part. The vertical adjustability of the roller upper part with respect to a roller holder of the roller part is achieved by means of an adjusting element which is displaceable by means of an adjusting screw. The adjusting element is preferably supported with at least one adjusting element bevel on a pendulum axle of the running roller holder and/or on an upper part bevel of the roller upper part.

Hinges are disclosed including: a first hinge portion; a second hinge portion; a biasing means; and at least one hydraulic damper; the first and second hinge portions are connected together and are arranged to pivot with respect to one another about a hinge axis between an open condition and a closed condition; the biasing means is arranged to bias the hinge towards the closed condition; the at least one hydraulic damper is compressed from an extended condition to a retracted condition as the hinge moves from the open condition to the closed condition; at least one of the hinge portions is arranged to attach to a gate; and wherein the at least one damper is located outside of the gate and inside one of the hinge portions.

Damped door closer systems, door assemblies including the damped door closer systems, and methods of operating damped door closer systems. The damped door closer systems include a closer assembly and damping assembly connected to each other through a connecting arm.

A door closer is provided. The door closer includes a first connecting plate and a second connecting plate. The first connecting plate is connectable to an external door frame, the second connecting plate is connectable to a door body connecting portion. Connecting rod assemblies and return springs are mounted in the door body connecting portion. One end of the connecting rod assembly passes through the second connecting plate and is hinged to the first connecting plate. When a door is opened, an external door body drives the first connecting plate and the second connecting plate to overturn, and after the connecting rod assembly pulls the door body connecting portion, the return spring is compressed. When the door is closed, the return spring pulls the door body to close automatically.
