Patent Application
20120248674
This invention generally relates to work-bench support tools and more specifically to non-slip work-bench support tools used to stabilize or support work pieces.
It is often convenient to elevate a wooden work piece when doing activities such as painting, drilling or routing. A problem with elevating a work piece is that clamps are typically required to prevent the work piece from slipping while work is being performed on the work piece. The use of clamps can be time consuming to set-up as well as potentially damaging to the surface of the work piece that is being worked on.
The present invention is directed toward an improved work-bench support tool that improves upon one or more deficiencies in the art.

The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
The first and second caps 102 and 112 fit into either end of the frame 114. The first and second cap 102 and 112 have a locating rib 106, as illustrated with reference to second cap 112. The outer peripheral shape of locating rib 106 corresponds to the inner peripheral shape of frame 114. The locating rib 106 extends axially into and seats within the cavity 116 formed and bounded by the sidewall portions of frame 114. This relationship ensures proper alignment between the first and second caps 102 and 112 and the frame 114. Alternatively, a plurality of holes and pegs could be provided between the first and second caps 102, 112 and frame 114 to locate the caps 102, 112 relative to frame 114.
The first and second caps 102, 112 may be adhesively secured to frame 114 using glue or other adhesives. The first and second caps 102, 112 could alternatively be ultrasonic welded to frame 114. Further yet, other means of securing the first and second caps 102, 112 to frame 114 could be implemented such as chemical bonding or mechanical catch arrangements to securely attach the first and second caps 102 and 112 to the frame 114. In a preferred embodiment, the first and second caps 102, 112 are sealingly attached to frame 114 such that internal cavity 116 is fully sealed.
In alternative embodiments, the locating rib 106 need not be a continuous rib, but could be a plurality of separate projections used to interact or engage the inner surface of the sidewalls of frame 114 to properly align the top and bottom caps 102, 112 relative to frame 114.
The frame 114 securely holds the first cap 102 and the second cap 112 and is of a similar geometric shape. The combination of frame 114 and first and second caps 102, 112 define and generally bound internal cavity 116 of the work piece support device 100. A flowable media or material 118, which may be composed of sand, granulized powder, beads of material, a liquid that is flowable at room temperature, etc, can be stored in internal cavity 116. Prior to sealing at least one of the first cap 102 or second cap 112 to the frame, the material 118 is placed in the cavity 116 formed by the frame 114 between the first and second caps 102 and 112. By using the flowable material 118, the center of gravity of the work piece support device 100 will adjust with the orientation of the device. This allows for lowering the center of gravity no matter the orientation of the work piece support device 100. Preferably, less than the entire volume of cavity 116 is filled with the flowable material 118 to allow for the adjustment in the center of gravity. Typically, 75% or less of the volume of the internal cavity 116 will be filled with the flowable media.
The frame 114 also has a support point or cone 108 and three receiving recesses or engagement holes 110 of reciprocating dimension to the cone 108. The cone 108 extends radially outward from a truncated corner of the frame 114. The cone 108 and engagement holes form mating male and female connections for coupling the work piece support device 100 with another work piece support device 100 (see e.g.
As such, the engagement holes 110 are generally conical cavities formed in the corresponding sidewall portions of frame 114.
As shown in
Preferably, the outer surface of both the first and second caps 102 and 112 are covered in a layer of a high grip material such as a thermoplastic elastomer 104 (see
A further feature of the work piece support device 100 is that it can also function as a support block 100 ideal for supporting a structure that is being painted.
The work piece support device 100 has TPE on at least three sides. TPE is on opposed sides of the work piece support device 100 defined by first and second caps 102, 112 that face axially away from one another. Further, the third side, provided by end 120, also includes TPE and is used when the work piece support device functions as a support block to elevate a work piece while painting. While not necessary, other embodiments can include TPE on the two sides that extend away from end 120.
The end cap 210 includes guide pegs 214, which act to locate the end cap 210 into the opening 206. Specifically, the guide pegs 214 align with an inner flange surface 212 of the body 202. The inner flange surface 212 creates a sealing pocket 216 for the end cap 210. In one embodiment, the guide pegs 214 retain the end cap 210 inside of the sealing pocket 216 by having guide pegs 214 with a slanted outer surface. The slanted outer surface of the guide pegs engage the inner flange surface 212 such that when the end cap 210 is inserted into the opening 206 the guide pegs 214 assert a radially outward directed force on the inner flange surface 212 thereby holding the end cap 210 in place. In another embodiment, the guide pegs 214 merely act to guide the end cap 210 into the pocket 216 where an adhesive is applied to the pocket 216 to retain the end cap 210. And in an even further embodiment, both the guide pegs 214 with the slanted outer surface and the adhesive are used to retain the end cap 210 in the pocket 216.
Additionally, the work piece support device 200 includes a support point or cone 208, and is covered on three sides by a layer of TPE 204. The cone 208 provides an ideal surface useful for supporting a work piece while painting, similar to the cone 108 discussed previously. Also, the layer of TPE 204 provides a slip resistant surface covering for the work piece support device 200, similar to the TPE 104 discussed previously.
Furthermore, while the illustrated work piece support devices 100 and 200 are generally triangular, the invention is in no way intended to be limited to this geometric shape.
