Abstract

A combination work table and vise. The work table is vertically adjustable and has a tiltable work platform which is tiltable about a longitudinal axis so as to provide a sloped working surface. The tiltable work platform also reduces the dimensions of the work table for transportation and storage. The work platform includes at least two leaves, at least one of which can be moved laterally relative to the other to provide a vise action between the leaves. Lateral leaf movement is accomplished by means of a hand crank and screw combination. The hand crank is rotatably mounted to a first leaf while the screw is threadedly engaged in a swivel block mounted to a second leaf. Rotation of the hand crank moves at least one leaf relative to the other and thereby accommodates clamping a workpiece between the two leaves in an action similar to the jaws of a vise. The swivel accommodates asymetrical, lateral movement of the second leaf thereby accommodating clamping of a nonsymetrical object between the two leaves. The hand crank may also be interconnected to a second swivel to provide both leaves with asymetrical lateral movement.

Claims

1. A work table comprising:

a basal framework; and

a tiltable work platform mounted on the basal framework, means for tilting the work platform relative to the basal framework the tiltable work platform comprising a framework and a working surface secured to the framework, the working surface comprising at least two leaves comprising a first and a second leaf with at least the first leaf laterally displaceable with respect to the second leaf, the framework comprising two parallel, spaced tracks upon which at least the first leaf is slideably engaged, a single centrally disposed screw, a crank for turning the screw, a journal bearing through which the screw passes and which serves as a thrust bearing for the screw, and a boss secured to the first leaf and threadedly engaged to the screw, rotation of the screw moving the boss and the first leaf laterally relative to the second leaf, the boss configurated as a swivel, the swivel accommodating unequal lateral movement of the first leaf relative to the second leaf to thereby accommodate clamping an asymetrical object between the two leaves upon rotation of the screw.

2. The work table defined in claim 1 wherein the work platform further comprises a workpiece with the first leaf being laterally displaceable to accommodate receipt of the workpiece as a third leaf between the first leaf and the second leaf.

3. The work table defined in claim 1 wherein the tiltable work platform includes two arcuate brackets whereby the work platform is mounted to the basal framework, the arcuate brackets each secured to and extending downwardly from a spaced track and accommodating pivotal adjustment of the tiltable work platform about a longitudinal axis.

4. The work table defined in claim 1 wherein the tiltable work platform and the basal framework includes means for selectively altering the vertical adjustment of the tiltable work platform relative to the basal framework.

5. A work table comprising:

a base, the base having a collapsible support stand pivotally connected to the base, the support stand providing a degree of vertical support to the base;

a trestle vertically adjustable relative to the base;

a work platform comprising;

a framework mounted to the trestle in a vertically adjustable relationship;

the work platform havng a longitudinal axis and means for tilting the work platform about the longitudinal axis;

the work platform also comprising a plurality of leaves with at least a first leaf laterally adjustable relative to a second leaf thereby accommodating relative lateral movement between the first leaf and the second leaf and accommodating clamping an object between the first leaf and the second leaf;

a single, centrally located screw secured by a journal bearing to the work platform; and

a swivel rotatably mounted to the first leaf to accommodate asymetrical lateral movement of the first leaf relative to the second leaf upon rotation of the screw.
