Portable, adjustable vertical work holder device
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.
1. A portable, adjustable vertical work holder device that comprises:
(a) a one piece base support having a downward facing curved, arcuate front view profile and a flat bottom view, said base support having a top and a bottom; and,
(b) a pair of opposing upright jaws connected to said base support, at least one of said pair of jaws being slideably mounted to said base support and having a locking means located thereon and being lockable and unlockable in plurality of positions along said base support;
wherein when the device is in its rest position, the jaws extend outwardly and further apart from one another traveling away from the base support.
2. The device of claim 1 wherein one of said pair of jaws is permanently and fixedly attached to said base support.
3. The device of claim 1 wherein said device is made of material selected from the group consisting of metal, plastic, and combinations thereof.
4. The device of claim 3 wherein said device is made of plastic.
5. The device of claim 4 wherein said plastic is selected from the group consisting of polyvinyl chloride, polyethylene, polypropylene, polyethylene polypropylene blends, acrylonitrile-butadiene-styrene, and polystyrene-containing material.
6. The device of claim 1 wherein said at least one of said opposing jaws includes a horizontal member connected to an upwardly extending vertical member, and said locking means is located on said horizontal member.
7. The device of claim 1 wherein said locking means is selected from the group consisting of a locking bolt, a swing lever lock, a ratchet and a pin and hole lock.
8. The device of claim 1 wherein each of said pair of jaws includes non-slip surface area.
9. The device of claim 8 wherein said non-slip surface area is selected from the group consisting of padding, grooving, and cross-hatching.
