Abstract
The application of stresses which might cause damage to a pipe or tube when the pipe or tube is held by a holder or clam can normally be avoided by using fins on the holder which resiliently engage the pipe and which do not press any sharp edges directly into the periphery of the pipe.
Claims12
A pipe holder having a body portion, means on said body portion for attaching said body portion to a support member, an at least partially cylindrical surface of larger diameter than a pipe to be held by said holder located on said body portion, and a plurality of fins for engaging a pipe located on said cylindrical surface so as to extend therefrom in which the improvement comprises:
- said fins being identical fins formed of a self-supporting, resilient, flexible material,
- each of said fins being of a substantially triangular cross-sectional configuration and having a base and two sides of unequal length, said sides being joined to one another by an apex and being joined to said base by corners, the base of each of said fins extending along and being joined with said cylindrical surface between said corners,
- when each of said fins is viewed in cross-section the angle between a line connecting the apex of the fin to the midpoint of a line extending between the corners of the fin and the latter line being such that as a pipe is held within said holder, the longer of said sides abuts said pipe such that the apex will not contact the periphery of the pipe so as to tend to be directed towards the periphery so as to tend to pierce it,
- the length of said line connecting said apex and the midpoint of said line extending between said corners being sufficiently long and the length of said line extending between said corners being sufficiently short so that said fin will be bent from its normal configuration between its apex and its base as it is used to hold a pipe, said fins being sufficiently resilient so that a pipe held by said fins is resiliently supported by said fins.
A pipe clamp comprising:
- a unitary structure formed of a flexible material formed to include;
- an upstanding side terminating in a flat bottom, said upstanding side having a generally rectangular cross-section;
- a vertical hole in said upstanding side forming a substantially circular opening in said cross-section;
- a body portion cantilevered from said upstanding side, said body portion having an opening therein which is semicircular in a cross-sectional plane bisecting said circular opening, said opening thereby being positioned to exert a vertical downward force component on a pipe placed between said opening and a surface when said flat bottom is placed on said surface and a fastener is inserted through said opening into said surface to create said force;
- and
- a plurality of tooth means positioned about said semicircular opening of said cantilevered member for applying said vertical force component to said pipe and for resiliently distributing said force component about said semicircular opening so as to relieve stress upon said pipe.
