Each coupling feature is arranged parallel to a long side of the base unit continuously between narrow sides of the base unit. The first coupling feature is formed for positive locking with a first mounting feature of the accessory module.

Abstract: Foldable travel case, comprising: a top and a bottom side (3), a hinge side (2) and at least one side surface (1), wherein the top and bottom sides (3), the hinge sides (2) and the at least one side surface (1) are connected to each other via connecting strips (4).

Abstract: A holder for a portable lock, which has a lock body having a locking mechanism and a spring-loaded button, has at least a first holding section and a second holding section that is disposed opposite the first holding section with respect to a reception space for the lock body, wherein the first and second holding sections are configured to engage around the lock body, when inserted into the holder along an introduction direction, at a first side and at a second side of the lock body that is disposed opposite the first side. The holder has, at least at the first holding section, a securing opening that is formed to take the button of the lock body into engagement in order hereby to secure the lock body against an unintentional release from the holder against the introduction direction.

Abstract: A lock, in particular a bicycle lock, includes a lock body, a locking element located outside the lock body, and a locking mechanism located outside the lock body for receiving and locking the locking element. The locking mechanism is connected to the lock body by a first rope section and the locking element is connected to the lock body by a second rope section. A length of a part of at least one of the rope sections extending outside the lock body is variable.

Abstract: A securing device for securing a component to an object comprises a fastening element having an engagement section and having a longitudinal axis, wherein the fastening element is selectively connectable to a counter element by actuating the engagement section; and a cover sleeve which is movably supported at the fastening element between a closed position in which the cover sleeve prevents an actuation of the engagement section and an open position in which the cover sleeve allows an actuation of the engagement section. At least one blocking element is provided between the fastening element and the cover sleeve, said blocking element being freely movable in the closed position of the cover sleeve between a latched position in which it blocks the cover sleeve in the closed position and an unlatched position in which it allows a movement of the cover sleeve into the open position.

Abstract: A protective cap for cylindrically mounted optical elements includes a retaining ring which is placed on a cylinder ring so as to be rotatable. The retaining ring covers the circumferential surface of the cylinder ring in a form-fitting manner. A latching mechanism having a latching element which engages in the latching mechanism in a force-fitting or form-fitting manner is present between the cylinder ring and retaining ring. The latching element is releaseable by an actuating element which is mounted on the retaining ring. A folding hinge for fastening and moving a protective cover from a covering position into a spatially fixed open position is present on the retaining ring.

Abstract: A support for an electronic appliance comprises a hollow profile 1 for disposing one or more electronic appliances 10 thereon. Within a first channel 4 which has a cylindrical basic shape, a similarly cylindrical connection plug may be positioned for connection to the electronic appliances 10, so that the connection plug is freely slidable in the longitudinal direction and at the same time pivotable within a predetermined angular range transversal to the support about the cylinder axis of the first channel 4. Thereby, one or more electronic appliances 10 may be stored on the support and may be conveniently and securely connected to the connection plug for charging their accumulators or for synchronizing the data stored thereon.

Abstract: A roller skate having enhanced durability and stability is disclosed. Furthermore, the roller skate is particularly adapted for affixing to a person's footwear, such as sneakers, boots or the like. The skate includes a platform for supporting a skater's foot. The platform includes a toe plate and heel plate connected by an adjustable connecting assembly. A front truck is affixed to the underside of the toe plate, while a rear truck is affixed to the underside of the heel plate. The front truck includes simple bracket arms for affixing a single front wheel which is capable of rotating, but not capable of tilting about the platform's longitudinal axis. Meanwhile, the rear wheel truck is mounted to the underside of the heel plate so as to permit both tilting movement about an inclined longitudinal axis, and also rotation about a transverse axis relative to the roller skate's platform. Preferably, the roller skate includes three wheels rotatably mounted to the rear wheel truck.

Abstract: A roller skate having enhanced steerability and stability is disclosed. The skate includes a platform for supporting a skater's foot and front and rear wheel trucks secured to the underside of the platform. A pair of front wheels is rotatably mounted in transverse axial alignment on the front wheel truck and a pair of rear wheels is rotatably mounted in transverse axial alignment on said rear wheel truck. The pairs of front and rear wheels are also in parallel axial alignment with each other and mounted on their respective wheel trucks for resiliently controlled, tilting movement about downwardly inclined longitudinal axis. In addition, a fifth wheel is rotatably mounted on the front wheel truck between the pairs of front and rear wheels and in parallel axial alignment with the wheel pairs. An additional preferred roller skate includes a single wheel rotatably mounted to the front toe plate. The front wheel is not tiltable about the skate's longitudinal axis.
