<p>The present invention is directed to a portable, adjustable vertical work holder device. The device includes a base support having an arcuate front view profile and a flat bottom view, and has a, top and a bottom. There is a pair of opposing jaws connected to the base support, and at least one of the pair of jaws being slideably mounted to the base support and having a locking mechanism located thereon to render the slideably mounted jaw lockable and unlockable in plurality of positions along the base support. One critical and unique feature is that the base support is yielding (semi-flexible) and will flatten under load. In some preferred embodiments, the pair of jaws are substantially flat jaws facing one another with a gap therebetween, and when the device is in a rest position without a workpiece, there is a first gap width closest the base support that is less then a gap width furthest from the base support. When a load is applied to the base support by placement of a workpiece between said pair of jaws and on the base support, the base support is flattened to a substantially horizontal side profile in a stressed position, and the pair of jaws become substantially parallel to one another to hold the workpiece.</p> |
