Plug-in connection system with at least one first element of a bendable first base body and one second element of a bendable second base body. The first base body can include can include an undercut into which a snap-in locking projection of the bendable first base body snaps into a securement segment of the bendable second base body. The first element and the second element can be developed as components of a climate or temperature chamber.

An operating lever assembly includes a fastening member having a retaining section releasably fastened to a first object, a receiving space and a locating section; and a lever member having a mating locating section and being movably connected at an end to the receiving space and at another end to a second object. Alternatively, the fastening member includes a retaining section and a locating section; and the lever member includes a mating locating section and a receiving space, to which the fastening member is movably connected. The fastening member can be pushed to release the retaining section from the first object, while the lever member is moved in the receiving space and the locating section is engaged with the mating locating section to hold the fastening member to the lever member, allowing the first object to be repeatedly and quickly separated from or fastened to the second object.

A connection device for interconnecting two components of plastics material is provided. The components include a first wall and a second wall, which have respective edges arranged against one another, when the two components are assembled. The device includes at least one clip on the first wall and extending beyond the edge thereof, at least one first tooth and at least one second tooth on the second wall and designed to be snap engaged by the clip when the two components are in the pre-assembled state and in the assembled state, respectively. The first tooth is closer than the second tooth to the edge of the second wall such that, when pre-assembled, the two components are connected by the edges of the first wall and the second wall, the edges being spaced apart from one another. The first tooth has an inclined locking face for facilitating decoupling of the two components.

Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically. A panel system including a plurality of rectangular panels with long and short edges which are mechanically connectable to each other along at least one pair of adjacent edges, said panels each being provided with a tongue and groove formed in one piece with the panels for mechanically locking together said adjacent edges at right angles to the principal plane of the panels, thereby forming a vertical mechanical connection between the panels, said panels being provided with a first locking element at one first edge formed in one piece with the panel and a locking groove at an opposite second edge, the locking groove being open towards a rear side or a front side of the panel.

A housing may include a first housing part and a second housing part. The first housing part may include a first latching contour having at least one first latching lug. The first housing part may include at least one further latching contour having at least one further latching lug. The second housing part may be connected to the first housing part via a latching connection. The second housing part may include at least one counter-latching contour.

A stackable storage system with a pressure sensitive lock where downward pressure on the first container causes a surface of a first locking portion on a first container to slide against an inclined surface of a second locking portion on a second container and causes the inclined surface of the second locking portion to pivot outward and snap back into place to connect the first container and the second container.

A press locked grating, in particular for use as a shelf for plate or heavy-duty shelves, has two longitudinal sides and cross members and longitudinal members having an I-shaped profile arranged between the longitudinal sides and at right angles to each other. The longitudinal members are inserted or pressed into punched holes of the cross members open towards the grating upper side. The longitudinal sides are formed in cross-section as a profile that includes at least first and second orthogonal legs. Each cross member has a punched hole at each end, in which the first leg is arranged and firmly connected thereto by a connecting method. The first leg is inserted or pressed into the punched hole, thereby achieving a first connection of the profile to the cross member, and has at least one deformation, thereby fixing the insertion or press connection of the cross member to the profile.

A fastening system includes a first connector and a second connector. The first connector has a protrusion, a first clip, and a first catch. The first clip and the first catch are offset from the protrusion. The second connector defines a slot, has a second clip, and has a second catch. The second clip and the second catch are offset from the slot. The slot is configured to receive the protrusion upon engagement between the first connector and the second connector. The first clip is biased into engagement with the second catch and the second clip is biased into engagement with the first catch upon engagement between the first connector and the second connector to secure the first connector to the second connector.

A composed element includes at least two panel-shaped elements, such as a locking tongue and groove connection, that are arranged to be coupled to each other at an angle, either directly or indirectly by means of an intermediate piece. The connection includes, at least at one of the panel-shaped elements, a tongue or groove, cooperable with a groove or tongue provided on the other panel-shaped element or on the intermediate piece. The tongue includes a split tongue, with at least a first part and a second part, and a slit located therebetween. A locking part is located at the outer side of at least said first part wherein the slit, seen in cross-section of the tongue, defines at least one side, the course of which, seen in cross-section, deviates from the main direction belonging to the tongue.

Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically. A panel system including a plurality of rectangular panels with long and short edges which are mechanically connectable to each other along at least one pair of adjacent edges, said panels each being provided with a tongue and groove formed in one piece with the panels for mechanically locking together said adjacent edges at right angles to the principal plane of the panels, thereby forming a vertical mechanical connection between the panels, said panels being provided with a first locking element at one first edge formed in one piece with the panel and a locking groove at an opposite second edge, the locking groove being open towards a rear side or a front side of the panel.
