Abstract
Abstract An elastic pipe clamp having a lower yoke, a fastener foot or the like for anchoring the lower yoke to a fixed surface and a cooperating upper yoke, the pipe being securely held between the yokes when they are locked together in a positive manner. A hinge-band pivotally connects one end of the upper yoke to one end of the lower yoke and mutually engaging locking hooks are provided on the opposite ends of the yoke from the hinge band for locking the yokes together. At least two (2) beaks on the hinged end of one of the yokes curve inwardly with respect to and over the hinge-band, the beaks being adjacent to the outer edges of the yoke with their outer arcs being tangent to the inside wall of the yoke. Cooperating recesses are provided in the other yoke that are open on their outer sides and have upper and lower walls with a radius curvature similar to the curvature of the beaks, whereby the beaks substantially fill the recesses when the clamp is closed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
266 words
An elastic clamp for a pipe or the like comprising: a lower yoke, means for anchoring the lower yoke to a fixed surface, a cooperating upper yoke, the pipe being securely held between the yokes when the yokes are locked together in a positive manner, a hinge-band pivotally connecting one end of the upper yoke to one end of the lower yoke, mutually engaging locking hooks on the opposite ends of the yokes from the hinge-band for locking the yokes together, at least two arcuate beaks on the hinged end of one of the yokes that curve inwardly with respect to and over the hinge-band, the beaks being adjacent to the outer edges of the one yoke leaving a recess therebetween, the surface of the arcs of the outer edges of the beaks being a continuation of the surface of the inside wall of the one yoke, cooperating recesses for the beaks in the other yoke being open on their outer sides and having upper and lower walls with a radius of curvature similar to the curvature of the beaks, the beaks substantially filling the cooperating recesses when the clamp is closed, the beaks being located on the upper yoke of the clamp and the cooperating recesses being located in the lower yoke clamp, and locking catches on the outer ends of the beaks, and cooperating catch surfaces at the opposite ends of the cooperating recesses from the ends through which the beaks are inserted, the catches of the beaks engaging the catch surfaces simultaneously with engagement of the locking hooks when the clamp is closed.
Claim 2
Dependent Claim
266 words
An elastic clamp for a pipe or the like comprising: a lower yoke, means for anchoring the lower yoke to a fixed surface, a cooperating upper yoke, the pipe being securely held between the yokes when the yokes are locked together in a positive manner, a hinge-band pivotally connecting one end of the upper yoke to one end of the lower yoke, mutually engaging locking hooks on the opposite ends of the yokes from the hinge-band for locking the yokes together, at least two arcuate beaks on the hinged end of one of the yokes that curve inwardly with respect to and over the hinge-band, the beaks being adjacent to the outer edges of the one yoke leaving a recess therebetween, the surface of the arcs of the outer edges of the beaks being a continuation of the surface of the inside wall of the one yoke, cooperating recesses for the beaks in the other yoke being open on their outer sides and having upper and lower walls with a radius of curvature similar to the curvature of the beaks, the beaks substantially filling the cooperating recesses when the clamp is closed, the beaks being located on the upper yoke of the clamp and the cooperating recesses being located in the lower yoke clamp, and locking catches on the outer ends of the beaks, and cooperating catch surfaces at the opposite ends of the cooperating recesses from the ends through which the beaks are inserted, the catches of the beaks engaging the catch surfaces simultaneously with engagement of the locking hooks when the clamp is closed.
Claim 3
Dependent Claim
29 words
The elastic clamp of claim 1 in which the catches on the beaks when engaged with the catch surfaces project beyond the outer wall of the lower yoke clamp.
