An electromotive furniture drive includes a drive unit and a power take-off unit which can be moved relative to the drive unit. At least one connecting element is arranged on each of the drive unit and the power take-off unit to respectively connect the drive unit and the power take-off unit to a furniture fitting. Each of the connecting elements provides at least two force application points in spaced apart relation for the connection to the furniture fitting in a direction transverse to the relative movement between the drive unit and the power take-off unit. The force application points are spaced apart from one another at least by a distance which is greater than approximately 50% of a displacement movement of the furniture drive.

A packaging machine includes a product belt, and an adjustment mechanism disposed at the product belt. The adjustment mechanism includes at least one hub movable about an axis of rotation, at least one support operably connected to the at least one hub, and at least one wrapping wand operably connected to the at least one support and movable by the support about the axis of rotation. The at least one wrapping wand is configured and disposed to position a wrapping material about an article to be wrapped. At least one adjustment mechanism is disposed at the axis of rotation. The adjustment mechanism is configured and disposed to alter a path of the at least one wrapping wand about the axis of rotation such that the path of the at least one wrapping wand maintains a constant distance from a product conveyed by the product belt.

A system for controlling the movement of a steerable multi-linked device may include a steerable multi-linked device, a feeder mechanism releasably connected to the steerable multi-linked device and a controller device. The steerable multi-linked device may include a first link, a plurality of intermediate links, and a second link movably coupled to a second one of the intermediate links. A first one of the intermediate links may be movably coupled to the first link. The controller device may be configured to control movement of the multi-linked device via the feeder mechanism.

A system that makes up at least a portion of a utilitarian article and having: a first body; a second body; and a first linkage assembly acting between the first and second bodies and configured to allow the first and second bodies to be relatively positioned to thereby reconfigure the article into which the system is incorporated. The first linkage assembly has first and second linkage parts. The first linkage assembly is configured so that: a) the first linkage part is movable relative to the first body around a first axis; b) the second linkage part is movable relative to the first linkage part around a second axis; and c) the second linkage part is movable relative to the second body around a third axis. At least one of the first, second, and third axes is non-parallel to the other two of the first, second, and third axes.

A sitting apparatus having: a frame; an upwardly facing surface on the frame for supporting a user in a sitting position; a first arm support on the frame defining a first surface against which a user's arm can be rested with the user in the sitting position on the upwardly facing surface; and a first connecting assembly acing between the frame and first arm support. The first connecting assembly and first arm support are configured so that the first arm support surface can pivot relative to the frame around at least first and second different axes to change a relationship between the first arm support surface and the frame.

An operating mechanism is provided for an electrical enclosure. The operating mechanism includes a switch operator, and a housing to house the switch operator. The switch operator includes a portion which extends through one of one or more holes in the electrical enclosure, and can be manipulated by an external handle to operate an electrical switching device, such as a circuit breaker, that is housed in the electrical enclosure. The housing includes a cavity to house and protect an external antenna or other electrical device, which is connectable to an electrical cable that extends from the cavity into an interior of the electrical enclosure via the hole(s). The electrical cable can be connected to a monitoring system inside of the electrical enclosure. The housing is mountable onto an exterior surface of a wall of the electrical enclosure to cover the hole(s).

The invention is an electromechanical stretching apparatus of a convertible sofa, which consisting of a mechanical stretching apparatus and an electric actuator, the mechanical stretching apparatus being provided with an electrically-driven connecting rod, wherein, the electric actuator consists of a motor, a motor connecting tube, a motor movable slider, and a motor head fixing part, the motor adopted is a motor with a guide rail, the motor movable slider is installed on the guide rail of the motor, the motor head is rotationally connected through a second rotor shaft to the motor head fixing part fastened on the electrically-driven connecting rod, the motor connecting tube is connected to the motor movable slider through a first rotor shaft and the motor connecting tube is fastened on the mechanical stretching apparatus. The said motor connecting tube is fastened on a linkage part of the mechanical stretching apparatus. The said first rotor shaft and the second rotor shaft are both a bolt. By changing the electronic driving device, the invention increases automaticity and comfort of the convertible sofa, and improves installation, removal, maintenance, and operation efficiency of an electric actuator of the convertible sofa.
