Definitions

  • This invention relates to a portable table for use by a carpenter.
  • This table can support timber materials of all sizes & dimensions within construction industry standards whether they be lengths of timber or sheets of timber material. The materials will be supported to an advanced degree as to provide unobstructed cutting lines making it easy to cut without the material collapsing to the ground, or for the need of saw horses or a second person to hold timber.
  • Some tables aimed at carpenters are already on the market but suffer from a number of disadvantages when cutting timber on site. For example, most don't provide a large enough platform. What would be useful is a table that is adjustable in terms of providing good surface area support while not obstructing the power tool blade. Most also only act like a clamp to secure small pieces of timber. Some are also made just to support lengths of timber & not capable of supporting large sheets of material for cutting safely and accurately on site.
  • Saw horses also have disadvantages. They are difficult to move with materials on them, they tend to be unstable and certain materials need four sawhorses to be cut safely. Also, unless you cut in a certain direction in relation to the horses, once cut, the material generally speaking, collapses to the ground unless you have three or more sawhorses.
  • the object of this invention is to provide a totally supported working platform/table to be used on a building site that will support any length of timber or a sheet of material during cutting while also providing unobstructed cutting lines without fear of collapse while in the process of single handily cutting the material to size.
  • Fig. 1& Fig.2 show the essential components of this invention consists of a table top or platform (a) with sturdy fold out legs (f) (g) to support it, that is adjustable in height in relation to the ground.
  • the table top or platform (a) consists of a large flat surface with a durable hard wearing material layer on top made from metal /plastic or timber on which a chop saw or mitre saw can rest. Ideally this will be rectangular in shape and of a large enough size as to support chopsaws/mitresaws of all makes and models, plus being large enough to use as a work bench.
  • Attached to this platform is a metal frame consisting of four large diameter square & rectangular hollow metal tubes (b),(c). Two of the four tubes are longer than the other two (b). The two longer tubes are laid underneath and along the length of the table top/platform and welded side by side (parallel) to one another. Fig. 17 & 19 illustrate this fact. The two shorter tubes (c) are then welded on top of the longer tubes but at 90° degrees to (b) in a position just to the side of the table top/platform (a). Fig. 2 shows this best.
  • the support arms will house the extendable support arms (b2) (c1) .
  • Fig. 7, 8& 9 illustrate this best.
  • the support arms will also be made of square hollow metal tubes but be of a slightly smaller diameter as to fit inside.
  • Fig. 16 & 18. They will slide within the two large and two smaller square metal tubes that make up the main frame attached to the work platform. They will slide in and out with ease on tough plastic sleeves or collars (y) that are made to fit between the large and small diameter tubes.
  • Each set of tubes will have one of these plastic collars. These collars will consist of a square shape plastic tube. Fig. 16, 17, 18, & 19. Each one will fit snugly inside each metal tube (b), (c).
  • the smaller diameter metal tubes (b2), (c1) will then slide inside the hollow square core of the plastic collar. This allows for a smooth frictionless surface for the smaller metal tube to move back and forth on rather than metal grinding on metal. This is an important quality feature!
  • Fig. 11 shows a bolt nut (z1) welded over a hole that is drilled through the centre of one side and at each end of the larger square metal tubes (b) .
  • the hole is drilled right through the plastic collars inside. The same is done to the shorter metal frame tubes (c), but the hole is drilled on the side in locations (l1), (l2) Fig. 3.
  • This bolt will have a handle welded on the end (as in this case) or a plastic moulded knob set on the head end to act as a handle.
  • Fig. 3(j1, j2, l1, l2) shows their positions.
  • extendable support arms (b2, c1) Tightening these handles results in the extendable support arms (b2, c1) being held at whatever position of length the user desires. This is an essential element that all the platforms must have.
  • Welded at one end of these extendable support arms is a short piece of square metal tube Fig. 6(r1, r2), Fig. 11(r1), Fig. 10(r4) , in this case the same diameter as the large square metal tubes used in the frame. These are welded in the vertical position i.e. (in relation to the arms).They will act as collars for the small adjustable support platform rods, Fig.10(q1, q2, q4) to sit in.
  • Fig. 3(k1, k2), Fig. 5(n1) On one side of these collars is the height adjustment facility Fig. 3(k1, k2), Fig. 5(n1) , which, as with the extendable support arms, consists of a hole being drilled through the centre of one side of the collar and then a bolt nut welded over the hole. This again allows for a regular bolt to be threaded into the nut.
  • This bolt will have a handle welded on the end (as in this case) or a plastic moulded knob set on the head end to act as a handle. Tightening this handle results in the support platform rod, Fig.10(q1, q2, q4) being held at whatever height the user desires. This is an essential element that all the platforms must have.
  • this rod Welded to one end of this rod is the support plate Fig. 6(x1, x2), Fig. 11& 12(x1) which consists of a thin metal plate.
  • This plate will have small holes drilled through it to allow a small wooden platform to be attached with small screws Fig. 11 & 12.
  • This wooden platform Fig. 1 & 2(d1, d2, d3, d4) to be replaced if over time it is damaged through wear and tear, plus being wood lessens the bruising damage that occurs when metal and wood collide.
  • Each leg is made from square, or in this case rectangular metal tubing sturdy enough to take the weight of not only the entire table frame but also the weight of any timber being put on the table.
  • Fig. 20 & 21 shows the details of a leg bracket (o) welded at one end and underneath the two shorter metal frame tubes (c).
  • the leg brackets constitute an upside down U-shaped piece of metal with two holes drilled through the two opposing sides of the bracket. Two of these brackets in all, one for each short metal tube.
  • Two legs (g) will also have holes drilled through two opposing sides at one end of the same diameter.
  • One leg each will then be slotted inside this bracket and a bolt (e1) with four washers (w1, w2, w3, w4) a spring washer (w5) and a nut (e2) will be slotted though all in sequence. This is part of an arrangement that will allow the entire leg assembly to be folded down for easy storage.
  • the next two legs Fig. 1(f) are of similar length but are attached with a bolt (e) half-way down nearer the middle and on the inside of the bracketed legs (g).
  • Fig. 22 & 23 shows this in detail. Two opposing holes are drilled through all four legs in this position and are the same diameter. As before with the leg brackets, a bolt (e), washers (w1, w2, w3), a spring washer (w5) and nut (e2) is slotted through. Once assembled, this results in the legs being paired up and able to swivel like the legs of an ironing board for example.
  • the two bracketed legs (g) will then have a metal crossbar Fig. 1(h) welded at 90° degrees in the lower portion of the legs. This crossbar will span both legs.
  • Another two crossbars will be welded at 90° degrees to span legs (f).
  • One will be welded in the lower portion of these legs in the same position as the crossbar on the legs (g), but set on the other side.
  • crossbars are essential for the stability of the table by stopping any lateral movement of the table when erect.
  • the crossbars do this by fixing one leg to the other, which keeps the legs square and at 90° degrees.
  • the next and more important crossbar will again span legs (f), but will be welded in-between the upper portion of the two inside legs.
  • This crossbar is illustrated in Fig. 1 & Fig. 6 as (s).
  • a foot shown in Fig. 4 & Fig. 5(m) will be moulded from rubber and inserted on the bottom of all four legs to enhance stability of the table.
  • Fig. 6(v) When unfolded the legs can be set in a number of angles to allow the table to sit at different heights. This is made possible by a pin set adjustment Fig. 6(v) .
  • This facility is shown in detail in Fig. 13, 14, & 15.
  • a small length of square metal tubing (v) is welded in a perpendicular position on the side of one of the larger square metal frame tubes (b) running underneath the table top/platform.
  • pin bracket (t) which consists of a U-shaped piece of metal, again with two holes drilled through the opposing sides and being welded on to the top centre of the top crossbar (s) of the inside leg assembly. It must be welded in the position which allows the pin bracket holes to slot over the pin-hole selector evenly on both sides. This results in all the holes lining up so a metal pin (p) can be slotted through in any of the pin-hole selector holes. This gives the table a height adjustment facility in relation to ground level, plus holds the table in the erect position.
  • the pin (p) itself will consist of a solid round cylinder shaped piece of metal that is long enough to go through the pin bracket and pin hole selector.
  • the pin itself is what holds the table in the erect position by not allowing the legs and table top/platform to fold up or drop down.
  • the worksite support table can be brought to the job (folded down) in a tradesman's van or truck, then carried single handily to the location of work and unfolded or erected simply by sitting the bracketed legs (g) on the ground, then swinging the table top (a) up and over. Then by bringing forward the pin bracket leg assembly (f, t,) and slotting the pin-hole selector (v) (located under the table top) down into the pin bracket (t). Once the appropriate height has been chosen by lining up the holes (u) of both the pin bracket and pin-hole selector, insert the pin. The table is now fully erected. To fold the table away again, reverse the process.
  • the operation is as follows. First, once the table has been erected, the left and right long extensions are released by untightening the locks Fig. 3(j1, j2). Now the extendable support arms Fig. 7(b2) are pulled out to the required distance to support a length of timber. Once this is done, the saw is rested on the table top in the most preferable position, generally this will be the centre and fix in place. A length of timber can then be rested on the base of the saw. Because not all makes of saw have the same base height, it becomes necessary to adjust the two support platforms (d1, d4) in height so that the timber not only rests on the saw base but also on the small left and right support platform evenly. This means that once cutting begins, of for example a length of timber, it is fully supported and will not lift or fall away immediately after the blade of the saw completes its cut.
  • Fig. 24 (d1, d2, d3, d4) 90°degrees in there collars Fig. 6(r1, r2) to support and hold any shape of material. Any combination of support platforms can be used and put into what ever position best suits the cutting process.
  • Laminated worktops which are used as kitchens worktops normally can also be cut with ease.
  • any tool whether powered or not, which requires that the material be held firmly so as to be used, can be, on this table. If required, a vice or clamp could also be an added feature. Tools such as Routers and Planers for example, require that the timber be held in position firmly. Obtaining this on site can be a real challenge slowing down work efficiency.
