Benefits of technology

It is an object of the present invention to provide a quick release strap clamp which is capable of accommodating increased levels of applied torque as compared with conventional strap clamps.
Another object of the present invention is to provide a quick release strap clamp in which a screw member can pivot relative to a screw housing to provide a release feature.
Another object of the present invention is to provide a quick release strap clamp in which a minimum number and size of apertures are formed in the strap resulting in increased strength.
Yet another object of the present invention is to provide a quick release strap clamp in which a relatively small number of simple components are utilized resulting in reliable long term operation.

Problems solved by technology

In the construction of typical prior art strap clamps, the attachment of the housing to the strap member has required the formation of various relatively large apertures in the strap to attach the housing with the consequent formation of areas of unwanted stress concentration and weakness in the strap.

Embodiment Construction

With reference to the drawings there is shown in FIGS. 1-7, a primary embodiment of a quick release adjustable strap clamp 10 according to the present invention which includes a strap band 12, a housing member 14 and a pivotally mounted screw member 16.

The strap band 12 is an elongated member which has a plurality of slots 18 formed in an orientation which is generally transverse or at a selected angle relative to the longitudinal axis of the strap band 12. The spacing between the slots 18 is uniform and generally corresponds to the pitch or spacing between the crests 20 of the threads 22 which are formed on the screw member 16.

The correspondence between the pitch of the threads 22, of the screw member 16 and the spacing of the slots 18 enables the screw member 16 to engage the strap band 12 and drive the strap band 12 in the manner of a worm drive as will be presently described.

The screw member 16 has a head portion 24 which includes a conventional driving connection such as a slot...

Abstract

A strap clamp includes a housing which is attached to an end of an elongated strap band. The housing pivotally support a screw member, the threads of which engage and drive the strap band to tighten or loosen the strap band. The screw member may be pivoted away from the strap band to disengage screw threads and release the strap band. The housing is attached to the strap band via elongated slots which have a minimal impact on the strength of the strap band.

Description

FIELD OF THE INVENTIONThe present invention relates generally to the field of strap clamps and more particularly to a quick release adjustable strap clamps which is capable of accommodating relatively high levels of applied torque.BACKGROUND OF THE INVENTIONThe prior art related to strap clamps and hose clamps includes a range of devices in which an elongated flexible steel strap includes a plurality of slots. A housing attached to an end of the strap supports a screw member, the threads of which engage the slots. Rotating the screw member draws the strap through the housing thereby tightening the clamp in the general manner of a worm drive.A recently developed application for this type of strap clamp is related to the attachment of various types of signs such as traffic signs to vertical posts or column masts. The advantages of such strap clamps include the elimination of a need to drill holes in the mast for insertion of bolts or other fasteners and the consequent elimination of a...
