Abstract

An extended workbench top comprises a work top hinged at its centre, allowing it to be folded in half into a storage position (fig 5). A non-slip mat 10 is provided on the work surface of the workbench top. Slotted apertures 1 may be provided to allow the extended workbench top to be attached to the top of a conventional workbench. Pivotally mounted extension arms 5, 6 may be provided, which may have clamping means. Extendable legs 4 may be hinged to the underside of the workbench top. The working surface area of the unfolded workbench top may be approximately 15 square feet (1.39m<2>).

Description

BACKGROUND FOR THE INVENTION

The workmate T.M bench is a collapsible workbench that is used worldwide in the D.I.Y and Building Industries, this only has a small working surface area. There are a number of devices to accommodate extra facilities for the workmate T.M bench. (Examples given as follows) U.S Pat Number 4,328,846 Dated 11-05-1982 U.S Pat Number 4,757,849 Dated 19-07 1988 U.S Pat Number 6,416,046 Bi Dated 09-07-2002 All of these are different in there application for the workmate T.M bench. They all have limitations for carrying large pieces of work.

The workbench T.M bench is a collapsible and clamping workbench comprised of two separate worktops connected on the top frame by means of two thread rods at right angles. The worktops are connected by means of a threaded carrier attached either side on the top frame of the collapsible workbench and fixed to the backbench worktop. The front workbench, being permanently fixed to the top of the collapsible frame.

DISCRIPTION OF PRESENT INVENTION

The present invention relates to an extension workbench top which will increase the working surface to the workmate T.M bench by approximately 150%. Thus allowing the workmate to carry large pieces of work such as full sized doors, kitchen worktop surfaces, 3 seated settee also circular and angled objects to be clamped.

The extension workbench top consists of a left hand and right hand worktop. The extension body is hinged at the centre by counter flap hinges, which will allow the workbench top to fold half its length for easy storage and portability.

A preferred embodiment and on the left underside of the extension bench top as at its disposal an elongated stop member at a set distance. At a right angle to the elongated stop member and to the front of the workbench extension top is provided and at a set distance is a slotted aperture.

Accordingly the left underside and at the back of the workbench extension top consists a slotted aperture at a set distance. Both slotted apertures are fitted to a set depth. The -embodiment of the right hand underside of the workbench extension top is the mirrored version of the left side. The underside of the extension bench top is designed to clamp to the workmate T.M bench when the workmate T.M bench is extended to its full working width. 1' 3

The underside of the workbench extension top by means of the left and right side guides front and back slotted apertures, it is fixed securely to the workmate T.M bench top. When the worlunate T.M bench top is retracted to its smallest width the workbench extension top is quickly released.

The left and right of the workbench extension top when in use has at its disposal in the front, first and second extension arms positioned at the front and either end of the workbench extension top that may rotate outwards at a right angle from the main body of the workbench extension top. Each extension rotating arm has incorporated in its centre and running the length of each rotating arm a trench at a set depth and length. On the outer end of each of the rotating arm is a cylindrical borehole opening through to the said trenches.

Incorporated in each borehole are imbedded threaded nuts. Threaded rods at a set length for the rotating arms screw though the said threaded nuts through the centre of the rotating arm trenches. The threaded rods traverse along the trenches by means of handles fitted to the outer ends of each threaded rod by rotating the said threaded rods clockwise and anti clockwise.

At one end of the said threaded rods and opposing the handles are incorporated inside the rotating arm trenches are fitted carrier blocks which traverse with the threaded rods along the said trenches. Each carrier block has on its upper most plain a cylindrical borehole. In each borehole is fitted a removable cranked rod. One end of the said cranked rod inserts into the cylindrical borehole down into the said carrier block.

The opposing end of the cranked rod protrudes upwards above the plain of the workbench extension top, on each rotating arm is fitted with a cylindrical borehole on the lower plain of a removable clamping block. When assembled together, the clamping blocks traverse along the plain of the rotating arms by the turning of the handles attached to the treaded rods.

The left and right back of the workbench extension top when in use at its dissal, a third and forth extension arms is positions at the back and either end of the workbench extension top that may rotate outwards at a right angle from the main body of the workbench extension top and directly opposite the first and second extension arm.

The third and forth extension arms each have at a set distance apart and along the centre of each arm four cylindrical boreholes. Each arm fitted with a removable clamping block which has a cylindrical shank formed in the block so as to fit the cylinder borehole. When in use the first, second, third and forth extension anns can clamp up to a width of 960mm.

S

At a set distance of the left side end body of the workbench extension top there is incorporated at the front-end a third trench at a set depth and set length. Through the front and into the trench is a cylindrical borehole incorporated in the borehole is embedded a threaded nut. A threaded rod at a set length screws through the said nut through the centre of the trench. The threaded rod traverses along the trench by means of a handle fitted to the outer end of the said rod by rotating the said handle clockwise and anti clockwise.

S

At one end of the threaded rod and opposing the handle is fitted a carrier block which traverses with the threaded rod along with the said trench.

The carrier block has on its upper most plain a cylindrical borehole. In the borehole is fitted a removable cranked rod. One end of the cranked rod inserts into the cylindrical borehole down into the said carrier block.

The opposing end of the cranked rod protrudes upward above the plain of the workbench extension top is fitted into a cylindrical borehole on the lower plain of a removable clamping block. When assembled the clamping block will traverse along the plain of the workbench extension top by the turning of the handles attached to the threaded rod.

Pertaining to the workbench extension top each corner is a copy of the left side font corner.

Accordingly the left back, right back and right front are all designed to the same clamping embodiment.

Incorporated in the underside of the workbench extension top there consists two drop extension legs set either end of the workbench extension top. Each leg consists of two members, first member consists a "T" section hinged at the "T" bar. The vertical drop on the "T" section comprises of a dovetailed trench at a set length with two cylindrical boreholes at a set distance apart in a central line down the vertical part of the "T" section. (0

The second part of the first member "T" section consists an upright section that is dove tailed at a set length that has two cylindrical boreholes at a set distance apart in a central line down the vertical of the dove tailed section. This allows the second member dovetailed upright to fit into the fist member dove tailed trench. When two members are fitted together one of the cylindrical boreholes can be put in alignment therefore allowing a tapered peg to be fitted.

Giving the "T" section leg two options to suit the working height of the workmate T.M bench giving the workbench extension top more rigidity and stability the second member of the "T" section is constructed and fixed as first member. 1. H
