Abstract
Abstract The present clamps are designed to be attached to a cabinet or shelf and applied in open form to the side of supporting poles that reach from floor to ceiling, the clamps serving when closed to support the cabinet or shelf at any desired height. Friction buttons of resilient material are compressed against the poles in the closing of the clamps to prevent slippage. Snap-action catches lock the clamps securely in place on the poles and there are no screws requiring tightening.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
In a construction of the character described the combination with an upright generally cylindrical pole serving as a support, a pole clamp for support of a device on the pole comprising two generally semicircular parts that are hingedly connected at one end for wraparound application to the pole, a spring catch on a substantially tangential extension of one end of one of said parts, an outwardly facing channel adapted to receive said extension provided on the free end of the other of said parts, the spring catch being engageable on the outer end of the web portion of said channel to lock the parts together in closed position, another tangential extension in rigid relationship to the clamp part carrying the spring catch and outwardly spaced relative thereto, and spaced projections on the outer side of the same clamp part and on the rigid extension for support of an article on said pole.
Claim 2
Dependent Claim
152 words
In a construction of the character described the combination with an upright generally cylindrical pole serving as a support, a pole clamp for support of a device on the pole comprising two generally semicircular parts that are hingedly connected at one end for wraparound application to the pole, a spring catch on a substantially tangential extension of one end of one of said parts, an outwardly facing channel adapted to receive said extension provided on the free end of the other of said parts, the spring catch being engageable on the outer end of the web portion of said channel to lock the parts together in closed position, another tangential extension in rigid relationship to the clamp part carrying the spring catch and outwardly spaced relative thereto, and spaced projections on the outer side of the same clamp part and on the rigid extension for support of an article on said pole.
Claim 3
Dependent Claim
43 words
A construction as set forth in claim 1 including resilient yieldable friction means compressible between the pole and at least one of the two semicircular parts in the closing thereof on the pole for frictionally resisting relative movement between the pole and clamp.
Claim 4
Dependent Claim
128 words
A clamp of the character described comprising two generally semicircular parts that are hingedly connected at one end for wraparound application to a cylindrical object, a spring catch on a substantially tangential extension of one end of one of the said parts, an outwardly facing channel adapted to receive said extension provided on the free end of the other of said parts, the spring catch being engageable on the outer end of the web portion of said channel to lock the parts together in closed position, another substantially tangential extension in rigid relationship to the clamp part carrying the spring catch and outwardly spaced relative thereto, and spaced hook means on the latter side of the same clamp part and on the rigid extension for article supporting purposes.
Claim 5
Dependent Claim
128 words
A clamp of the character described comprising two generally semicircular parts that are hingedly connected at one end for wraparound application to a cylindrical object, a spring catch on a substantially tangential extension of one end of one of the said parts, an outwardly facing channel adapted to receive said extension provided on the free end of the other of said parts, the spring catch being engageable on the outer end of the web portion of said channel to lock the parts together in closed position, another substantially tangential extension in rigid relationship to the clamp part carrying the spring catch and outwardly spaced relative thereto, and spaced hook means on the latter side of the same clamp part and on the rigid extension for article supporting purposes.
Claim 6
Dependent Claim
27 words
A clamp as set forth in claim 3, wherein both halves of the clamp are molded of one piece resilient plastic material hingedly connected by a pin.
