Abstract
A pipe clamp for attaching a duct to a base surface. The pipe clamp has a clamp body with an aperture for arranging the pipe clamp around the duct, a tightening element for keeping the ends of the clamp together, and a spring nut arranged on the second end of the clamp body and provided with a set of resilient lips with free ends facing one another, engaging the tightening element. The spring nut has a baseplate with a through-opening for the shank, and a set of connecting arms. The resilient lips are situated at a distance from the baseplate and are respectively connected to an associated connecting arm which extends substantially transversely to the resilient lip.
Claims9
A pipe clamp for attaching a pipe to a wall, ceiling or another base, comprising:
- a clamp body having a first clamp halve and a second clamp halve, which are hingedly interconnected at one end by a hinge and each have at their other end an integral first flange and an integral second flange, respectively, wherein an aperture for arranging the pipe clamp around the pipe is delimited between the flanges,
- the first flange having two lips with a slotted opening between the two lips, which slotted opening is open at an outer end of the first flange, the second flange having an opening disposed therein,
- a tightening element which comprises a head and a shank, the shank extending through the opening in the second flange, the shank being receivable in the slotted opening of the first flange so as to engage the head behind the two lips,
- a spring nut which abuts against the side of the second flange facing away from the first flange and is spaced apart from the first flange, the shank of the tightening element being received in the spring nut,
- wherein the spring nut has a baseplate with a through-opening for the shank and a pivot arm extending from the baseplate through an aperture in the clamp body above the second flange, the pivot arm pivotally securing the spring nut to the clamp body,
- wherein the spring nut further comprises a pair of connecting arms that are integral with the baseplate that extend up from the baseplate at a side thereof remote from the pivot arm, said connecting arms each having a 180° bent portion so that a main portion of each of said connecting arms is spaced apart from the baseplate at the side thereof facing away from the second flange, the main portion of each connecting arm being integral with a resilient lip of a first set of resilient lips of the spring nut, said resilient lips each extending substantially transverse to the main portion of the connecting arm and each having a free end, the free ends of the resilient lips facing one another and the shank being received between said free ends.
