An adapter device for detachably fastening instruments and equipment to a side rail of an operating table includes a clamping device by means of which the adapter device can be clamped to the side rail of the operating table, a longitudinal profile onto which the instruments and equipment can be detachably fastened, and a joint having at least one pivot axis formed between the clamping device and the longitudinal profile so that the longitudinal profile is pivotable relative to the clamping device about the pivot axis of the joint.

Particular embodiments disclosed herein provide a joint of a tray arm assembly, comprising a joint body, a shaft configured to rotate relative to the joint body about a longitudinal axis of the shaft, and a slip clutch assembly, comprising a clutch stack, including a plurality of first clutch plates keyed to the shaft and a plurality of second clutch plates keyed to the joint body. The clutch stack further comprises a spring configured to selectively exert a force on the clutch stack, wherein the force compresses the clutch stack causing a friction between the plurality of first clutch plates and the plurality of second clutch plates with respect to a rotation of the shaft relative to the joint body.

A plant training system for use with a pot that is arranged to hold a plant includes a plurality of bases that are adapted to be coupled to the pot, wherein each base is adapted to carry a stake or pole, and wherein the angle of the stake or pole relative to the pot is adjustable. There is a mechanical system for holding each base on the pot.

The present invention relates to a modular rotatable link for use for a plate on which a piece of hardware, such as a card terminal or tablet, may be secured. The modular rotatable link comprises a base section, a rotation ring, a body section, and a fastener. The body section may be of different form and functionality.

A support arm system (10) has at least one lockable articulated connection (16). A locking device (20) is associated with the articulated connection (16). The locking device (20) includes a passive drive (32) as well as an actuating device (36) associated with the locking device (20) with an active drive (38). The active drive (38) acts in the same plane as the passive drive (32).

A securing element for securing a spindle in a bushing, in particular for a medical stand device, includes a supporting portion configured to arrange the securing element in a predefined axial position on a supporting apparatus of the stand device, and an engagement portion configured to interact with a spindle rotatably supportable about an axis of rotation in the supporting apparatus, or a pin of the stand device, to secure the spindle or pin in a predefined axial position relative to the supporting apparatus rotatably within the supporting apparatus. The securing element can be supported in at least one radial position on the supporting apparatus, in particular in a mounting preparation position and/or a securing position, wherein the engagement portion is configured to interact with the spindle or the pin by engagement in the radial direction, in particular in the securing position. The securing element may also be secured in several radial positions and comprise coupling portions that are formed correspondingly. Also disclosed are components correspondingly formed to the securing element, in particular a supporting apparatus, a cover for the supporting apparatus, and a coupling element; and a securing system, or a securing mechanism, or a mounting set each comprising at least one securing element according to the invention.
