Abstract

An adjustable leg, collapsible sawhorse, wherein roller-style attachments are secured to multi-jointed, pivotable arms that are slidably related to the sawhorse support structure, wherein the roller-style attachments facilitate upload, support, cut and offload of a large workpiece, such as a 4′×8′ sheet of plywood, by a single person, and wherein the roller-style attachments hang unobstructively below the sawhorse support surface when not in use.

Description

TECHNICAL FIELD

The present invention relates generally to sawhorse devices and, more specifically, to a multi-positional sawhorse device enabling a single user to upload, support, cut, and offload large sheets of wood via multi-positional support members.

BACKGROUND OF THE INVENTION

Home repair and home renovation projects and improvements continue to be popular tasks for many, notwithstanding the multitude of tools required and the frequently cumbersome and heavy building materials. Unfortunately, many do-it-yourselfers are relegated to limited work areas and often realize limitations in the diversity of materials that can be utilized without the assistance of another individual. Construction workers, too, face similar challenges, wherein efficiency is constrained by the necessity for more than one worker for a given task.
Sawhorses are one means by which one engaged in construction activities can support an oversized workpiece, such as during sawing or drilling. Sawhorses are especially convenient because they are frequently foldable, and thus portable and easily storable, rendering sawhorses beneficial to many users. Nonetheless, limitations to the benefits remain. For example, if a large (such as 4′×8′) piece of plywood is to be extended between two sawhorses for work thereon, typically one individual cannot accomplish placement for such a task, wherein at least two people are required to lift the wooden sheet up and over the sawhorses, and then to lower the board to the support surfaces thereof. Further, upon sawing down the middle of such a wooden sheet supported in such a position, the sheet separates and, without further support from one or more individuals or additional devices, necessarily falls, creating a potentially dangerous situation following completion of the cut.
Sawhorses have been proposed to enable easier manipulation of workpieces supported thereon. Some such devices include upwardly extending roller arm(s), including some that may be positioned either parallel or perpendicular relative to the upper support edge of the sawhorse. In view of the present invention, however, such sawhorses are disadvantageous because users are denied the use of the full sawhorse support rail in order to benefit from the roller attachment, wherein the roller must receive the entire force of the workpiece. In another type of sawhorse device, a roller is angularly disposed along a side edge of the sawhorse in order to enable benefit from the roller during loading and unloading, yet without preventing use of the sawhorse upper support surface. Others offer free-standing rollers in an effort to enable the beneficial use of a roller in cooperation with full sawhorse support. Still, however, these roller and sawhorse combinations are disadvantageous in view of the present invention, and none offer a selectable means for supporting the cutting edge following completion of the cut.
Therefore, there is a need for a multi-positional sawhorse device enabling a user to mount, store and utilize a plurality of adjustable roller arms on a foldable, height adjustable sawhorse support base, wherein each roller arm is adapted for use on either side of the sawhorse, wherein each roller arm is slidably adjustable along the length of the sawhorse, and wherein convenience features such as on-board power and tool organizers facilitate overall ease of use, thus preventing the above-discussed disadvantages.

BRIEF SUMMARY OF THE INVENTION

Briefly described, in a preferred embodiment, the present invention overcomes the above-mentioned disadvantages and meets the recognized need for such a device by providing an adjustable leg, collapsible sawhorse, wherein roller-style attachments are secured to multi-jointed, pivotable arms that are slidably related to the sawhorse support structure, wherein the roller-style attachments facilitate upload, support, cut and offload of a large workpiece, such as a 4′×8′ sheet of plywood, by a single person, and wherein the roller-style attachments hang unobstructively below the sawhorse, support surface when not in use.
According to its major aspects and broadly stated, the present invention is a configurable sawhorse with a dual-track mount system installed lengthwise on the underside of the sawhorse support surface, wherein accessories may be mounted to the sawhorse to facilitate convenient use thereof, and wherein such accessories may include a multi-segment, dual-locking-joint pivotable arm with a 180° range of motion relative to the sawhorse mount, and a further 180° range of motion of one arm segment relative to another arm segment, such that a multitude of adjustably selectable positions is available for the pivotable arm and the roller feature provided thereon.
More specifically, the present invention in its preferred form is a multi-positional sawhorse device, wherein a length-adjustable elongate support member extends between two pairs of extendable legs, and wherein roller arms are pivotably and slidably related to the elongate support member for additional support of workpieces therewith. The length-adjustable elongate support member is defined by two outer support members, with an inner support member housed therewithin and adjustably therebetween, wherein the degree of exposure of the inner support member relative to the respective outer support members determines the overall length of the elongate support member of the sawhorse.
The underside of each outer support member is adapted with a mounting track, wherein track-adapted brackets may be slidably mounted therein, and adjustably positioned, preferably along the length of the elongate support member. Each roller arm is pivotally secured to a track-adapted bracket, and is installed with each roller capable of an orientation parallel to the elongate support member of the sawhorse. Each roller arm may simply hang in a downward direction during non-use, or may be pivotably extended in either direction relative to the elongate support member of the sawhorse. A similarly pivotal hinge enables selectable movement of the roller, via an extension arm, relative to the roller arm.
Each of the foregoing adjustable features is easily lockable following selection, via snap-style buttons. Additionally, the tension of the roller is also adjustable, via an onboard tension selector. Further features include a non-slip support surface and non-slip feet, and a foldable, cross-support arm for extension between the legs. Additional optional features include an attachment plate for a table saw, such as a contractor saw or miter saw, a power strip for on-board AC power for accessories, and organizational hangers for tools.
A feature and advantage of the present invention is the ability of such a device to enable a single user to upload, support, cut, and offload large sheets of wood.
Another feature and advantage of the present invention is the ability of such a device to enable a user to quickly, easily, and selectively position the device and the onboard accessories.
