Four-position machine carousel

[0001] The present invention relates generally to multi-functional work bench devices and, more specifically, to a four-position machine carousel enabling a user to mount, store and utilize four power tools in a limited space, wherein each piece of equipment is mounted on an individual surface of the carousel and selective rotation of the carousel to a desired position enables user access to a chosen tool and surrounding work surface.

[0002] Woodworking continues to be a popular hobby for many, notwithstanding the multitude of specialty tools required. Even those who focus their shop work on household repair and home renovation projects typically require multiple pieces of equipment such as sanders, drills, various saws including miter saws and scroll saws, and numerous hand tools including screw drivers and wrenches. Safe utilization and storage of even a common assortment of power tools necessitates free space.

[0003] Free surface space enables manipulation of workpieces and machines relative to one another. Surrounding free space is needed for complex or large projects and for storage of associated hand tools and accessories. Unfortunately, many do-it-yourselfers, wood working enthusiasts and craftsmen are relegated to limited work areas and often realize limitations in the diversity of their shop equipment due to spatial constraints.

[0004] Multi-purpose workbenches have been proposed that enable one surface to interchangeably mount a variety of machines or power tools, wherein a hobbyist could theoretically utilize one workbench as a support module for any one piece of equipment from an assortment thereof. In view of the present invention, however, such workbenches are disadvantageous because users are repeatedly faced with burdensome operational delays while they switch out equipment from a remote storage location to a workbench mount. Notwithstanding inefficient use of time, such dismounting and mounting of machines also may be prohibitively physically demanding for many individuals, considering that power saws, drills and the like are typically very heavy and unwieldy.

[0005] In attempts to avoid the limitations of multi-purpose workbenches with interchangeable mounts, workstations have been described wherein more than one tool or machine remains mounted thereto at all times. Such multi-tool workbenches are intended to enable a user to select between at least two different machines without a significant time loss. In view of the present invention, these multi-purpose workbenches are also disadvantageous.

[0006] Some multi-purpose workstations are dimensioned to receive and mount numerous tools thereon, wherein a selected tool is slidably moved across a large work surface to a user access position and a non-selected tool is slidably moved to a remote area of the work surface. While this type of design does prevent a user from having to lift and mount a machine for use because all of the machines remain mounted thereto at all times, the dimensions of such a vast work surface does little to alleviate potentially large spatial requirements.

[0007] Another type of multi-purpose workstation has a dual-work surface configuration, particularly wherein one type of saw is mounted on one side of a planar surface and another type of saw is mounted on the other side. If a user needs a table saw, he flips the planar surface so that the table saw is upright and the opposing machine is hanging upside down. This, too, is disadvantageous in view of the present invention. This dual-machine workstation is limited, by design, to two machines. Moreover, turning the mounting surface from one side to the other may also be too physically demanding for many individuals due to the weight and dimensional complexities of such saws.

[0008] Revolving workstations offering three work surfaces have been also been suggested, wherein a triangularly shaped center support retains tools mounted thereto. The triangular design that forms the basis of this type of device is disadvantageous in view of the present invention, wherein only three tools may be mounted thereon. Moreover, the available selection of tools that may be mounted on the available triangular workstations is further limited by height constraints that must be imposed on selected machines or power tools to allow for rotation of the three-sided, prismatic centerpiece.

[0009] Therefore, it is readily apparent that there is a need for a four-position machine carousel enabling a user to mount, store and utilize four power tools in a limited space, wherein each piece of equipment is mounted on an individual surface of the carousel, wherein the support frame is fully height adjustable to accommodate a variety of machine heights, and wherein selective rotation of the carousel to a desired position is mechanically assisted, thereby enabling quick and easy access to four mounted power tools of varying dimensions, thus preventing the above-discussed disadvantages.

[0010] 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 a four-position machine carousel enabling a user to mount, store and utilize four power tools in a limited space, wherein each piece of equipment is mounted on an individual surface of the carousel and selective rotation of the carousel to a desired position enables access to a chosen tool and surrounding work surface.

[0011] According to its major aspects and broadly stated, the present invention is a generally cube shaped machine carousel having a generally central rotational axis, wherein each of four outer surfaces of the carousel can receive and secure a machine or power tool thereon, wherein the rotational support members for the carousel are height adjustable, and wherein a hand-crank and locking gear mechanism enables easy rotation of the carousel and secure selection of rotational positions.

[0012] More specifically, the present invention in its preferred form is a multi-surface, rotational action workbench, wherein four generally square surfaces together define a generally cube shaped carousel with two substantially framed sides. At least one framed side preferably has at least one drawer and a central cross-support with a central rotation support point extending therefrom. A gear mechanism is provided with a handle, wherein rotation of the handle activates the gear mechanism and rotates the carousel, and wherein a locking mechanism is provided to restrict the gear mechanism and lock the carousel into position.

[0013] The carousel is supported by two upright members and diagonal cross-supports, wherein a power supply line is substantially contained within one of the upright members to prevent any limitations in carousel rotation. Each upright member also includes a pivot support mount capable of securely receiving a central rotation support point of the carousel, thereby supporting and enabling rotation of the carousel. Substantially unlimited height selectable and adjustable positions are available for each telescoping upright member, wherein the selected position and height is secured via an internal height adjustment mechanism. The mechanism is positioned within each upright member, wherein a centrally positioned, threaded member has an upper end that responds to rotation of a height selection arm via a cross-member, geared height adjustment rod. User rotation of the height selection arm initiates cooperative movement of each upright member via rotation of a generally internally carried support plate along the threaded member. A crank assisted mechanism enables adjustment of the height of the carousel supports, enabling accommodation of a variety of machine dimensions.

[0014] The two upright members are supported by a generally rectangular base frame. The base frame includes four casters, one positioned at each corner, to enable movement of the multi-surface, rotational action workbench, and two of the four casters are locking to enable fixed positioning thereof.

[0015] A feature and advantage of the present invention is the ability of such a device to provide storage and utilization of four pieces of equipment in a space typically required for one piece of equipment.

[0016] Another feature and advantage of the present invention is the ability of such a device to enable a user to quickly and easily change from one piece of equipment to another.

[0018] Another feature and advantage of the present invention is the ability of such a device to provide a gear-assisted means for rotation of a multi-surface workbench.

[0019] Another feature and advantage of the present invention is the ability of such a device to provide a multi-surface workbench with easily accessible on-board electrical power.

[0020] Another feature and advantage of the present invention is the ability of such a device to enable free rotation of a work surface without potential interference from electrical supply lines.

[0021] Another feature and advantage of the present invention is the ability of such a device to enable securely locked positioning of the four-surface carousel.

[0022] Another feature and advantage of the present invention is the ability of such a device to prevent tool and machine mounting limitations by enabling height and clearance selections.

[0023] Another feature and advantage of the present invention is the ability of such a device to enable selectively mobile relocation or fixed positioning of a multi-surface workbench.
