1,166,933. Releasable fastenings. F. MULLER and H. MULLER. 2 March, 1967 [3 March, 1966], No. 9985/67. Heading E2. [Also in Division F2] A suspension device for suspending an object from a substantially horizontal element (for example a ceiling) comprises a carrier member 2 adapted to be fixed to the said element so as to depend therefrom; a suspension strap 1 for embracing the object to be suspended; and a clip 8; wherein the carrier member includes a downwardly extending fixing lug 5 formed with a substantially horizontal slot 6 and opposed abutment surfaces below the slot and at least one of the strap end portions in use being passed through the slot, bent over, and held against the abutment surfaces by the clip. When the object to be supported is a pipe the strip 1 can either be passed around the pipe in a loop and both end portions passed through the slot in opposite directions and secured by the clip or alternatively one end portion can be passed through the slot and secured by the clip 8 and the other end portion can be passed around the pipe and secured to an intermediate part of the strap by a second clip. When the object to be supported is an appliance two of the caster members are used, one end portion of the strap is fixed to one carrier member 2 by passing it through the slot 6 and securing it by means of the clip 8 and the other end portion of the strap is secured to the second carrier member 2 by a second clip 8. The clip or clips are resilient and embrace the strip portion or portions. The carrier member shown is made by bending a strip of metal so as to provide a head part 3 and the downwardly projecting lug 5 and a. nut 4 is secured to the head part for attaching the carrier member to the support. In a modification instead of the. nut being fixed to the head part it is loose and its upper surface is curved so that the remainder of the carrier member can rock relative to the nut. In another construction the lug is a separate part which is pivoted to the head part so that it can rock. In an alternative construction the lug is made of sheet metal, and is attached to and depends from a sleeve nut or threaded stud. Constructions of the carrier member are also described in which the slot is either provided in, or partly defined by a movable plate fixed in an aperture in the lug so that the strap can rook. The form in the which the carrier member is bent from sheet metal and provided with a nut secured to its head part can be provided with recesses in the edges of the head part so that the carrier member can be engaged with a rail of channel shape as an alternative to securing it by means of a screw in the threaded nut. |
