Here, the pillar coupling portion comprising a contact face curved to lie against pillar and a boring for receiving a fastening member which is oriented such that the bracket when fastened to the pillar is attached by the fastening member inserted from the bracket and into the pillar in a radial direction of the pillar. The series of brackets comprises brackets with element coupling portions adapted to be fastened to each of the playground elements in the series of playground elements, and all the brackets in the series comprise essentially identical pillar coupling portions such that all the brackets are adapted to be attached to the pillars in the same way. The invention also relates to a method of assembling such a playground. The series of playground elements may include floor panels, side panels, a series of bars of predefined diameters and chains.

A modular frame comprising a connector (3), a first frame member (1, 2) and a second frame member (1, 2), wherein the first frame member (1, 2) comprises one or more engagement members (5, 7) profiled to key with a first slot (6) on the connector (3) and a second slot (8) on the second frame member (1, 2).

A mechanical lock for building component connection includes a plug element (1) and a lock bod part (2). The plug element (1) includes a plug shell (10), a plug pin structure (11), and a plug transmission structure. The plug pin structure (11) is movably installed in the plug shell (10). The plug transmission structure is in transmission connection with the plug pin structure (11). An end of the plug pin structure (11) is provided with a stop part (110). The lock bod part (2) includes a lock body shell (20), a bracing structure (21), and a lock body transmission structure. An insertion channel (23) matched with the plug pin structure (11) is formed in the lock body shell (20). The lock body transmission structure is in transmission connection with the bracing structure (21).

A coupling member includes: first, second, and third portions each having a flat plate-like shape; and a fillet portion. The first portion has a first side and a second side orthogonal to each other. The second portion is bent at the first side relative to the first portion, and extends to an inner surface of the first portion. The third portion is bent at the second side relative to the first portion, and extends to an inner surface of the first portion. A bend radius of an outer surface of the coupling member at the first side is equal to a bend radius of a surface of a first extending member facing the first side. A bend radius of an outer surface of the coupling member at the second side is equal to a bend radius of a surface of a second extending member facing the second side.

An interconnect system for coupling first and second frame members includes female and male interconnect members. The female interconnect is secured to the first frame member and has defined therein a receptacle. The male interconnect member is secured to the second frame member and defines a protrusion configured for selective axial insertion into, and mating engagement with, the receptacle. The receptacle extends axially between a receptacle opening through which the protrusion is axially received and a receptacle rear wall at which the receptacle terminates. The protrusion terminates at a protrusion tip. The receptacle and protrusion are furthermore configured such that at least one of (a) the receptacle and the protrusion are complementarily keyed in order to prevent relative rotational displacement of the male and female interconnect members when they are in mutual mating engagement, and (b) the protrusion tip is magnetically attracted toward the receptacle rear wall.

A connection device for an exhaust gas turbocharger has an essentially bent first element and an essentially bent second element. The first element and the second element are detachably connected with each other in a first end region or in a second end region, respectively, and are movably connected with each other in a third end region or in a fourth end region, respectively. A first supporting portion extends between the first end region and the third end region and a second supporting portion extends between the second end region and the fourth end region. The connection device comprises a recess which is formed in the element for the reduction of stresses.

A modular frame comprising a connector (3), a first frame member (1, 2) and a second frame member (1, 2), wherein the first frame member (1, 2) comprises one or more engagement members (5, 7) profiled to key with a first slot (6) on the connector (3) and a second slot (8) on the second frame member (1, 2).

A connection device for a frame, the connection device comprising a body comprising: a first engagement member (1) and a second engagement member (2). Said body comprises a sealing flange (13) which is configured to extend in parallel alignment with a first flange (7) of a first beam (4) and with a second flange of a second beam when the first and second beams are connected to the connection device via the first and second engagement members (1, 2) respectively, and which sealing flange (13) comprises a first recess (14) configured for receiving the first flange (7) of the of first beam (4) when the first beam (4) is connected to the connection device via the first engagement member (1), and a second recess (15) configured for receiving the second flange of the second beam when the second beam is connected to the connection device via the second engagement member (2).

A connection device for an exhaust gas turbocharger includes an essentially bent first element and an essentially bent second element. The first element has a radially extending first clamping arm in a first end region and the second element has a radially extending second clamping arm in the first end region opposite the first clamping arm. The first element is movably connected with the second element in a second end region. The first clamping arm and the second clamping arm may be movably connected by a first connecting element of the connection device. The first element comprises a first supporting portion and the second element comprises a second supporting portion between the two end regions. A stiffening element is formed in a transition region between the clamping arm and the supporting portion for increasing the strength of the connection device.
