Benefits of technology

[0019] An advantage of the present invention is that it provides a tool for pushing parallel boards together, and is suitable for use with a variety of differently sized joists or studs.

Problems solved by technology

A number of devices have been developed in the past to aid in the installation of flooring and other parallel boards, but they have had a number of deficiencies which make them difficult to use.
Obviously, this would not work if the floor is being installed over a plywood subfloor.
Too narrow a span will prevent the gripper from fitting over the joist.
Most are undesirably complex and expensive.

Embodiment Construction

[0025] The present invention provides a novel tool as a useful and convenient means for pushing boards together when building decks or, for example, installing sub-flooring over joists. It can also be used for pushing plywood sheets tightly together, such as for house framing and underlayments for roofs and for other purposes.

[0026] The boards, plywood or other materials, do not necessarily have to be 90 degrees to the supporting joist when they are being pushed by this tool. Any divergent angle of overlay over ajoist, stringer or stud can be accommodated.

[0027] As shown in FIGS. 1 and 2, tools for installing parallel boards by pushing them together are known to include an elongated lever (100) having a rotatable cam (50) pivotally affixed adjacent to a distal end of the lever for pushing the parallel boards, and a gripper body (200) having two lugs (300) for gripping a joist or stud, extending downward from the lower end of the gripper body. For example, the lugs (300) straddle a...

Abstract

A carpentry tool for the installation of parallel boards includes an elongated lever having a rotatable cam pivotally affixed adjacent to a distal end of the lever, a gripper body pivotally affixed at a distal end of the lever, the gripper body having two lugs or brackets extending downward from the lower end of the gripper body, wherein the gripper body includes a two-piece telescopic section having an outer tubing member and an inner tubing member in slidable engagement, the inner tubing member including a first lug or bracket on a lower face thereof, the outer tubing member including a second lug or bracket on a lower face thereof, opposing the first bracket, and a spindle extending from an upper face thereof, and a mechanism for reversibly affixing the sliding inner and outer tubing members at predetermined points. Further disclosed are novel adjustable joist grippers for use with the apparatus.

Description

REFERENCE TO RELATED APPLICATIONS [0001] This application claims an invention which was disclosed in Provisional Application No. 60 / 565,619, filed Apr. 27, 2004, entitled “IMPROVED RESCUE TOOLS”.
