Abstract: A communication system for exchanging data between an actuator system and an external device, e.g. an operation where the communication system in the form of a gateway and a codex interprets the information in the bidirectional data stream and communicates the information on both sides. The communication system is furthermore provided with an RFID circuit integrated in a handset. The RFIC circuit can communicate information about the gateway's unique identification, also known as an MAC-address. This achieves easy connection of an external device to the actuator system without having to enter data manually.

Abstract: A linear actuator comprising a cabinet (1), an electric motor (2), a transmission (4), a gear housing (11), a spindle nut (6), a spindle (5), the actuator being furnished with an opening (20) in the gear housing (11), where a gear wheel power take-off (21) is accessible and may be equipped with optional equipment. The gear wheel power take-off (21) is constructed as a tooth gearing on a planetary wheel holder (16) in a planetary wheel and transfers a movement to the optional equipment, which is proportional to the movement of the spindle nut during its travel on the spindle.

Abstract: Height-adjustable work table, preferably kitchen table comprising at least one cabinet on top of which a table top is located. The cabinet(s) is located on a number of electrically driven height-adjustable platforms. In that the platforms are mutually retained by at least one connection rail these appear as stable both during the assembly of the work table and of the assembled table. Between a surface, typically a floor on which the platform is located, and an underside of the cabinet a toe kick is placed. This toe kick is telescopic in height such that the toe kick regardless of the adjusted height of the kitchen table shuts off access under the cabinet. The connection rail may constitute an element of the telescopic toe kick.

Abstract: A communication system for exchanging data between an actuator system and an external device, e.g. an operation where the communication system under the form of a gateway and a transcoder interprets the information in a bidirectional stream of data and distributes the information to both ends. The communication system is furthermore provided with a logger function, where the signals that are sent out to both sides of the gateway, are stored in a memory, so that the actions and signals that lead to an alteration on the actuator can later be reconstructed.

Abstract: Wall-mounted cabinet comprising a body (1) on each side of which is arranged a linear actuator (4). The linear actuator comprises a spindle (6) with a spindle nut, where the spindle is driven by a reversible electric motor via a transmission. The spindle nut is attached directly or indirectly to the side of the body (1), such that the body is lowered or raised in dependency of the direction of the revolution of the motor. The construction has the advantage that the internal of the body is completely clean for mechanical parts which lowers and raises the body. Moreover, the actuators only take up minimum space on the outer side of the body.

Abstract: Linear actuator comprising a housing (1), a reversible electric motor (7), a transmission (22), a spindle (5) driven by the electric motor through the transmission (22), a bearing (31) for embedding the spindle (5), a spindle nut (6) secured against rotation on the spindle, an outer tube (3) surrounding the spindle, an activation element (4) telescopically embedded in the outer tube (3) and connected to the spindle nut (6), a rear mounting (9) designed as a separate element and secured in the housing for mounting of the actuator. The rear mounting (9) is equipped with a seat (35) for the bearing (31) of the spindle. The seat (35) is connected to an opening (36), which is guided out on the side of the rear mounting (9), so that the bearing (31) of the spindle may be inserted sideways in the seat (35). Thus a linear actuator is provided having a rear mounting which is easier to mount and ensures an easier handling during the assembly of the linear actuator.

Abstract: The invention relates to an actuator for operating a positioning element. A common requirement in such actuators is that the positioning element can be decoupled from the electric motor that drives the positioning element via a transmission. In some applications the actuators are so compact that the only way to decouple the actuator is to disassemble parts of the actuator. To connect the positioning element to the electric motor again, this however requires that the whole actuator is demounted so as to ensure that the disassembled parts are properly assembled. The present invention overcomes this problem by providing an actuator comprising two toothed wheels which by mutual displacement can be brought out of mesh and which each comprises at least two toothed rims positioned with a spacing corresponding to at least the width of one toothed rim.

Abstract: A linear actuator system comprising at least one linear actuator, a power supply, a control and an operation device.

The servo motor assembly further comprises a printed circuit board (16), a microprocessor (17) and at least one switch (19,20) connected to the brake activator (7). The servo motor assembly can further comprise a motion sensor (18). The servo motor assembly of each castor is connected to an electric brake controller (33) of the castor control system. The castors can be operated from an operating panel (37) of the castor control system (28).

Abstract: A linear actuator with a support that includes a bearing support frame, a bearing, a worm wheel, and a spindle, the bearing support frame being configured to support and secure the bearing, the bearing being configured to support the worm wheel and riveted to the worm wheel and the spindle; and the worm wheel and the spindle are riveted. The present invention enables the actuator to run more stably and at least doubles the service life of the product; reduces the requirement of the precision of parts such as motor housing and back fixture, and ensures that the service life of the product meet requirements even when the dimension of a few parts is inaccurate; and therefore eliminates the abnormal noise generated by the spindle of the actuator.

Abstract: A linear actuator includes a back fixture formed of a first part, a second part, and a plastic bearing, the first part connecting with the second part, grooves are disposed inside the first part and the second part, and extra structures are disposed outside the plastic bearing. The plastic bearing is secured inside the first part and the second part with the grooves and extra structures. The back fixture can be directly fitted onto a bed frame by applying a certain force to make an elastic deformation of this back fixture, thereby accelerating the installation of the actuator. This not only significantly reduces the noise caused by the connecting portion during the operation of the actuator, but also reduces the wearing of connecting parts, thereby significantly extending maintenance-free life.

Abstract: Lifting column, preferably for height adjustable tables, said lifting column comprising at least two relative to each other telescopically arranged members (2a, 2b, 2c). At least one slider (11) is arranged between the two members (2a, 2b, 2c), said slider being secured to one of the members (2b). The problem is play between the members (2a, 2b, 2c), resulting in an unstable lifting column. For solution of this problem the member (2b) to which the slider (11) is secured, is furnished with a resilient section (17) outlined by a groove (16, 18) against which at least a part of the slider (11) rests. The resilient section (17) can push the slider (11) into firm engagement against the two members (2b, 2c), at which a stable lifting column which is free from play is achieved.

Abstract: An electric actuator system for hospital and care beds comprising at least one linear actuator (9,48) for adjusting the lying surface of the bed. The actuator (9,48) used for adjusting the backrest section (6,57) of the bed comprises means for registering the force which it is exposed to. By comparing the registered forces to a zero value and/or a force interval, it can be determined whether the person occupying the bed is in the process of leaving the bed or has already left the bed. A connected alarm can thus notify the staff that the bed-bound person is in the process of leaving the bed.
