Abstract

A clamp for adjustably mounting an airspeed indicator to a webbing. The clamp is configured as a pair of planar jaws designed to clamp the webbing when tightened by a bolt passing through the jaws. Each jaw includes a socket half so that a socket is created when the jaws are brought together. A resilient hoop is used to encircle the barrel of the airspeed indicator in a resiliently constrictive manner. A ball is mounted to the external periphery of the resilient hoop and is configured to be received in the socket and clamped therein when the jaws are clamped to the webbing.

Claims

1. A clamp for adjustably affixing an airspeed indicator to a webbing strap comprising:

an elastic hoop adopted to have a diameter incrementally smaller than the diameter of the airspeed indicator, said elastic hoop being operable for stretchably receiving the airspeed indicator in a constrictive, frictional relationship;

a ball mounted to said elastic hoop;

a webbing clamp;

having a first jaw, said first jaw having a first socket half at a first end and

a second jaw, said second jaw having a second socket half at a first end, said second jaw cooperating with said first jaw in a face-to-face relationship to engage said ball between said first socket half and said second socket half;

release means on said webbing clamp for releasably mounting said webbing clamp to the webbing strap, said release means comprising a first gripping face on a surface of a substantially planar portion of on a second end of said first jaw and a second gripping face has been inserted after "a second gripping face" on a second end of said second jaw, said webbing clamp adopted to releasably the webbing strap between said first gripping face and said second gripping face when said ball is engaged between said first socket half and said second socket half;

said webbing clamp having a hole through said first jaw and said second jaw; and

screw means passing through said hole for bringing said first jaw toward said second jaw, said screw means causing said first jaw and said second jaw to simultaneously engage said ball and the webbing strap in a clamping relationship.

2. The clamp defined in claim 1 wherein said ball comprises three orthogonally intersecting planar elements, each planar element having a circular profile to unitedly form a spherical profile of said ball, said planar elements reducing shrinkage discontinuities in said ball during injection molding of said ball and limiting frictional engagement between said ball and said socket.

3. The clamp defined in claim 1 wherein said first jaw comprises a first back, said first back having a plurality of raised first ribs and a raised platform, said raised platform receiving said hole through said first jaw, and said second jaw comprises a second back, said second back having a plurality of raised second ribs with a receptacle between said raised second ribs, said receptacle receiving a threaded nut therein in snap-fit relationship and said hole in alignment with said threaded nut.

4. A clamp comprising:

a first jaw having a first back and a first socket half at a first end;

a second jaw having a second back and a second socket half at a first end;

release means for releasably mounting said clamp to a webbing strap, said release means comprising a first planar face on a second end of said first jaw and a second planar face on a second end of said second jaw, said first planar face having a first gripping surface and said second planar face having a second gripping surface, said first gripping surface and said second gripping surface adapted to releasably engage the webbing strap therebetween;

a first hole through said first jaw;

a second hole through said second jaw;

bolt means passing through said first hole and said second hole for urging said first planar face against said second planar face with said first socket half and said second socket half forming a socket between said first jaw and said second jaw;

a ball configured to be received in clamping relationship in said socket; and

an elastic hoop mounted to said ball and said ball being mounted in said socket whereby said elastic hoop extends outwardly from said clamp when said ball is in said socket.

5. The clamp defined in claim 4 wherein said second jaw comprises a nut receptacle on said second back, said nut receptacle receiving a threaded nut therein in a snap-fit relationship, said receptacle holding said nut in alignment over said second hole.

6. The clamp defined in claim 4 wherein said ball comprises three orthogonally disposed planar elements oriented along orthogonal axis, each planar element having a dimensionally equal circular profile thereby providing said ball with a spherical profile.

7. The clamp defined in claim 4 wherein said elastic hoop is adopted to have an inside diameter incrementally less than the external diameter of an airspeed indicator thereby enabling said resilient hoop to releasably grasp the airspeed indicator.

8. The clamp defined in claim 4 wherein said first back and said second back comprise raised ribs to increase the rigidity of said first jaw and said second jaw.

9. A method of releasably supported an airspeed indicator on a webbing strap comprising the steps of:

mounting a ball to an elastic hoop;

preparing a clamping means for releasably securing said ball to the webbing strap, said preparing step comprising forming a first jaw and a second jaw, said first jaw having a first socket half at a first end and a first, planar gripping face at a second end, said second jaw having a second socket half at a first end and a second, planar gripping face at a second end, providing a screw means on said clamping means for bringing said first jaw in juxtaposition with said second jaw and forming a socket with said first socket half and said second socket half;

engaging said ball in said socket;

releasably clamping said jaws to the webbing by engaging the webbing strap between said first, planar gripping face and said second, planar gripping face frictionally engaging the airspeed indicator in said elastic hoop.

10. The method defined in claim 9 wherein said mounting step comprises forming said ball with recesses therein, said recesses defining said ball as three orthogonally intersecting planar elements, each planar element having a dimensionally equal circular profile, said recesses reducing shrinkage deformities of said ball during injection molding of said ball and also limiting frictional engagement between said ball and said socket.

11. The method defined in claim 9 wherein said step of providing a screw means comprises bringing said first jaw and said second jaw together by passing said screw means through said first jaw and said second jaw and tightening said screw means in a threaded nut.

12. The method defined in claim 11 wherein said step of providing a screw means includes releasably securing said threaded nut on a back surface of said second jaw thereby precluding losing said threaded nut.
