A door closer system is provided that includes a motor, a spring, a reduction gear set, and a rack and a pinion mechanism. The spring and pinion may be coupled to the rack, and the pinion may be selectively coupled to the gear set. The motor may be selectively mechanically coupled to the gear set. The pinion may rotate in a first direction via the rack as the spring is compressed in a second direction opposite the first direction as the spring is expanded. The motor is operable to rotate and act upon the pinion through the gear set, thereby rotating the pinion in the second direction and assist the spring in closing the door.

A furniture drive for moving a furniture part includes a housing to be located on or in a furniture panel, and an actuating arm mounted movably relative to the housing and on which the movable furniture part can be fastened, and the housing has an end face through which the actuating arm protrudes in a relative position. A spring device can exert a force onto the actuating arm, an adjusting device can adjust the force that can be exerted onto the actuating arm by the spring device, and a display device can display the force adjustment carried out by the adjusting device. The display device is formed separately from the adjusting device and can be read in an installed position of the furniture drive, in which position the housing is located completely, except for the end face, in the furniture panel of the furniture body.

An exemplary indicator mechanism is configured for use with a door closer including a body and an adjustment screw. The indicator mechanism generally includes an indicator, at least one indicium, and a cycloidal drive. The cycloidal drive is configured to selectively align the indicator and the at least one indicium in response to rotation of the adjustment screw to thereby indicate an operating characteristic of the door closer.

A door drive mechanism includes a main drive and an auxiliary drive.

In this connection it is provided that the drive assembly of the auxiliary drive is formed as a drive assembly with a linear output and that the drive assembly of the auxiliary drive is borne in a pivot bearing and that the rod system is formed as a slide arm and the rod system bearing is formed as a slide rail.

A pneumatic door closer includes a rotary energy-storing mechanism including a housing and a driving mechanism. The driving mechanism includes a cylinder, a second piston assembly and a sealing element, the sealing element is in an air tight connection with the cylinder and the second piston assembly, to form a closed space filled with high pressure gas in the cylinder. The second piston assembly drives the closed space into a first air chamber and a second air chamber in communication with each other. The driving mechanism also includes a first piston assembly connected to the second piston assembly. The pneumatic door closer also includes a transmission mechanism having one end received in the housing and another end connected to the door frame.

A door drive mechanism includes a main drive and an auxiliary drive.

In this connection it is provided that the components of the main drive and of the auxiliary drive to be mounted on the door leaf side are borne in or on a common and/or continuous housing mechanism and/or bearing framework mechanism and/or mounting plate mechanism to be mounted on the door leaf side and/or are covered by a common and/or continuous cover to be mounted on the door leaf side.

A double-doored lid apparatus includes: a box body; first and second doors; an opening/closing mechanism that opens and closes the first and second doors in conjunction with each other; a locking mechanism that locks the first and second doors in their closed states; an urging member that urges the first and second doors in an opening direction while the doors are locked by the locking mechanism; and a support member that transmits the urging force from the urging member to the first and second doors. The support member includes: a first support portion that supports one end portion of the urging member; and second and third support portions that start to come into contact with the first and second doors, respectively, before the doors reach a predetermined locking position during closing motions thereof, and that support the first and second doors when the doors are locked by the locking mechanism.
