Patent number: 9915076Abstract: A coupling member includes a hook-shaped coupling part arranged to be hooked into a gripping part of an upright and a locking arrangement switchable between a locking position and a release position. Further, the locking arrangement includes a pivotally attached first clamping part and a wedge-shaped locking part, which is slidable between a locking position and a release position. The wedge-shaped locking part is arranged to push the first clamping part towards the upright and the gripping part by means of wedge action. Moreover, the first clamping part comprises two transversally spaced apart side parts which jointly define a cavity there between. The first clamping part is arranged externally on the hook-shaped coupling part, and is arranged partly within the cavity. Further, each of the side parts includes fastening means for pivotal attachment of the first clamping part to the hook-shaped coupling part.Type: GrantFiled: September 27, 2012Date of Patent: March 13, 2018Assignee: PLUSEIGHT TECHNOLOGY ABInventor: Harry Wallther

Patent number: 6530456Abstract: The invention relates to scaffolding, especially facade scaffolding, comprising vertical poles (11) located one behind the other, preferably in pairs, and interconnected at given vertical intervals by means of cross struts (12). Said vertical poles (11) consist preferably of individual elements (11′) and form support frames (43) with said cross struts (12). Base plates (13) are also positioned between the cross struts (12) of neighbouring support frames (43). Diagonal poles (27) are arranged between at least some of the neighbouring vertical poles (11). According to the invention, scaffolding of this type is configured in such a way that at least one end of the diagonal poles (27) engages in an aperture (16) provided in the designated vertical pole (11) by means of a hook (15, 15′). Said opening lies at least essentially in the plane defined by the axes (17) of the neighbouring vertical poles (11).Type: GrantFiled: December 19, 2001Date of Patent: March 11, 2003Assignee: PlusEight Technology ABInventor: Harry Wallther

Patent number: 4509711Abstract: A device for detachably supporting a work stand to a wall surface (2) for example. This includes a supporting member (4) which originates from the securing surface and which can be hooked up, by means of a coupling device (3) fitted to the supporting member, in a holder element (1) fixed to the wall surface. This is formed like a plate-shaped body which comprises at least one supporting surface adapted to be fixed to the wall surface (2) and two hooking-up portions which are directed away from one another and each of which has its own bearing surface facing the wall surface (2). The coupling device (3) comprises two portions (11) which are provided with guide surfaces facing one another. Between them these form a gap adapted to receive the holder element. Situated in the gap are locked members (16, 22) which are each hooked up by their own hooking-up portions. A device (21) is able to be changed over between a locking position and a releasing position.Type: GrantFiled: April 27, 1982Date of Patent: April 9, 1985Assignee: Stallningsgruppen i Goteborg AktiebolagInventor: Harry Wallther
