A furniture hinge device capable of implementing wide range loading, comprising a housing and a fixing plate. A linkage assembly is provided between the housing and the fixing plate. A lever assembly and a power assembly are provided on the housing. The power assembly comprises a primary spring and a secondary spring. Positioning ends of the primary spring and the secondary spring are respectively mounted, from bottom to top, at a lower swinging end of the lever assembly. An adjustment assembly is provided on connection ends of the primary spring and the secondary spring. A fixing part of the adjustment assembly is fixedly mounted on a side plate of the housing. Adjustment parts of the adjustment assembly are respectively rotatably connected to the fixing part of the adjustment assembly and are connected to adjustment ends of the primary spring and the secondary spring.

Apparatus and methods for assembling, installing, and operating a manually operated gate (e.g., a safety gate). The manually operated safety gate can include a gate frame and a spring assembly. The gate frame can include a proximal upright member, a distal upright member, an upper arm, and a lower arm. The proximal upright member can be anchored to a stationary surface. The upper arm and lower arm can be pivotably coupled to the proximal upright member and distal upright member to form a parallelogram. The manually operated gate can be configured to pivot between self-close position and a closed position at a constant angular velocity. A kit can contain the required structural components and instructions and can be used to assemble the manually operated gate assembly.

A display case including a frame with a first fastener, a door with a second fastener, and a bracket coupling the door to the frame is described. The bracket has a first end coupled a second end. The first end is pivotably coupled to the frame by the first fastener. The first end includes a first pair of spring arms having a first slot to couple to the first fastener and to allow the door to pivot between open and closed positions. The second end is slideably coupled to the door by the second fastener. The second end has detents on a second pair of spring arms and a second slot to allow the second fastener of the door to slide as the door is pivoted between open and closed positions. A first detent is positioned further from the first end of the bracket than a second detent.

An exemplary housing assembly is configured for use with a door operator. The housing assembly generally includes a bracket configured for mounting to the door operator, a case configured to at least partially enclose the door operator, and an attachment mechanism configured to selectively couple the bracket with the case. In certain forms, the attachment mechanism includes a resilient clip arm formed on one of the bracket or the case, and a tang formed on the other of the bracket or the case. The resilient clip arm is configured to engage the tang to maintain engagement between the bracket and the case.

A method for mounting a door drive including a door actuator with a mounting section for the attachment to a counter-mounting section of a door, an attachment device for the attachment to a counter-attachment section of the door and a lever mechanism with a first end and with a second end, for the mobile support of the door actuator at the attachment device between a closing position and an opening position, where the attachment device is disposed at the first end of the lever mechanism and an axle assembly of the door actuator at a second end of the lever mechanism, and with an actuating unit of the door actuator for moving the axle assembly of the door actuator.
