Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
221 words
A suspension device for supporting a channel of substantially U-shaped section, said channel having two legs with inwardly projecting flanges at the free ends of said legs, said device comprising an arm, a coupling member attached to one end of said arm, said coupling member comprising a pair of parallel extending end faces and a cross face connecting said end faces thereby forming a substantially Z-shaped cross section, said arm and said coupling member being formed of a single T-shaped strip of sheet material, a recess between said arm and said coupling member the width of which is smaller than the distance between said flanges so that when said coupling member is inserted into said channel and rotated at least one of said end faces will engage a leg of said channel and said flange will be in cooperative engagement with said recess overhanging said end faces so that said coupling member will be securely held within said channel, and a lock which can be slid over the arm formed as a plate having a central aperture and a lug bent out of the plane of the plate, said lug, when adjacent the profiled rod, being clamped with its two parallel sidewalls between one of the end faces of the coupling member and one of the flanges of the profiled rod.
Claim 2
Dependent Claim
221 words
A suspension device for supporting a channel of substantially U-shaped section, said channel having two legs with inwardly projecting flanges at the free ends of said legs, said device comprising an arm, a coupling member attached to one end of said arm, said coupling member comprising a pair of parallel extending end faces and a cross face connecting said end faces thereby forming a substantially Z-shaped cross section, said arm and said coupling member being formed of a single T-shaped strip of sheet material, a recess between said arm and said coupling member the width of which is smaller than the distance between said flanges so that when said coupling member is inserted into said channel and rotated at least one of said end faces will engage a leg of said channel and said flange will be in cooperative engagement with said recess overhanging said end faces so that said coupling member will be securely held within said channel, and a lock which can be slid over the arm formed as a plate having a central aperture and a lug bent out of the plane of the plate, said lug, when adjacent the profiled rod, being clamped with its two parallel sidewalls between one of the end faces of the coupling member and one of the flanges of the profiled rod.
Claim 3
Dependent Claim
125 words
A suspension device for supporting therefrom a U-shaped rod comprising, an arm formed of a flat piece of sheet material, a pair of end flaps attached to one end of said arm extending in opposite parallel directions and substantially perpendicular to the plane of said arm, so that when said arm is inserted into said rod between the legs of said U-shape and rotated said flaps will engage the inside surfaces of said legs, said legs having flanges overhanging said flaps so that said arm is securely held between the legs of said U-shape, and a locking member comprising a flat plate having a slit-shaped aperture therein and means for extending into said U-shaped rod for engaging and locking said flaps between the legs thereof.
Claim 4
Dependent Claim
125 words
A suspension device for supporting therefrom a U-shaped rod comprising, an arm formed of a flat piece of sheet material, a pair of end flaps attached to one end of said arm extending in opposite parallel directions and substantially perpendicular to the plane of said arm, so that when said arm is inserted into said rod between the legs of said U-shape and rotated said flaps will engage the inside surfaces of said legs, said legs having flanges overhanging said flaps so that said arm is securely held between the legs of said U-shape, and a locking member comprising a flat plate having a slit-shaped aperture therein and means for extending into said U-shaped rod for engaging and locking said flaps between the legs thereof.
Claim 5
Dependent Claim
80 words
The device according to claim 2 wherein said means for extending into said rod comprises a pair of lugs attached to said plate and extending perpendicular to the plane in the same direction therefrom so that when said plate is slid onto the arm through said aperture, said lugs will extend into the rod between the legs of said U-shape and be engaged between one of said flaps and one of said legs so as to lock said flaps therein.
