A kit of parts includes a ceramic element comprising a cylindrical bore having at least one recess, and a rod comprising an outer tube comprising a jutting portion adjacent to an insert portion. An outer tube wall mates with the cylindrical ceramic bore. An outer tube bore comprises a cylindrical portion. An outer tube projecting member is insertable into a recess in the cylindrical bore. An inner mandrel insertable into the outer bore stabilizes a projecting member in a recess to couple the rod to the ceramic element.

A conversion component of a suction cup holder for photography equipment includes a fastening component; and a locking component fixed on the fastening component. The locking component includes a locating member fastened on the fastening component, a movable member movably located between the fastening component and the locating member, and a resetting member arranged between the locating member and the movable member. A connecting member which is configured to be connected with photography equipment can pass through the fastening component and can be locked under a cooperation of the fastening component, the movable member and the resetting member.

A snap joint for securing construction modules together on a modular construction site, the snap joint comprising a male member mounted on a first construction module and a female member mounted on a second construction module. The female member housing locking members, a tumbler and biasing members biasing the locking members against the tumbler. The male member having shaft engageable within the female member, through a base stop of the tumbler, along a trigger path in a manner to push the tumbler out of interference with the locking members, thereby freeing the locking members to transversally engage with the shaft.

A retaining unit comprising: a first member configured to be movable; a second member used in an unmovable fixed state; and a pressing element attached to the second member, and configured to press the first member to engage the first member with the second member, wherein the retaining unit is configured such that the first member can be moved by release of the engagement with the second member when a force at a predetermined level or higher is applied in a movement direction of the first member, and the pressing element is assembled with the second member to constitute a unit.

A build plate-clamping assembly may include a work station having a build plate-receiving surface and a lock-pin extending from the build plate-receiving surface of the work station. The lock-pin may include a hollow pin body, a piston disposed within the hollow pin body, with the piston axially movable from a retracted position to an actuated position, and a plurality of detents, with the plurality of detents radially extensible through respective ones of a plurality of detent-apertures in the hollow pin body responsive to the piston having been axially moved to the actuated position. A methods of working on workpieces may include lockingly engaging a build plate at a first work station, performing a first work-step, releasing the build plate from the first work station, lockingly engaging the build plate at a second work station, and performing a second work-step. An additive manufacturing system may include a vision system with a first build plate-receiving surface and an additive manufacturing machine with a second build plate-receiving surface.

The present disclosure relates to a shaft adapted to be at least partially inserted into an opening of a shaft receiver. The shaft comprises a nominal shaft portion adapted to be at least partially inserted into the opening of the shaft receiver, followed by an intermediate shaft portion that in turn is followed by a guide shaft portion terminating the shaft. The shaft comprises a cross-section with a cross-sectional contour in a plane including the central axis, the cross-sectional contour comprising a nominal shaft portion contour of the nominal shaft portion, an intermediate shaft portion contour of the intermediate shaft portion and a guide shaft portion contour of the guide shaft portion. The cross-sectional contour comprises a radial direction being perpendicular to the central axis, wherein, as seen in the radial directio, the nominal shaft portion contour is located at a nominal radial distance from the central axis.

A conversion component of a suction cup holder for photography equipment includes a fastening component; and a locking component fixed on the fastening component. The locking component includes a locating member fastened on the fastening component, a movable member movably located between the fastening component and the locating member, and a resetting member arranged between the locating member and the movable member. A connecting member which is configured to be connected with photography equipment can pass through the fastening component and can be locked under a cooperation of the fastening component, the movable member and the resetting member.

The present invention relates to a device for locking a connection element to a tube as well as a system comprising the same. The device is configured such that the securing segment of its securing element is automatically engaged with a recess of the connection element when the connection element has reached its locking position within the tube. Thus, the connection element is locked in the tube. Furthermore, the present invention relates to a method for locking a connection element in a tube.
