Definitions

  • This invention relates to workbenches, and worktables therefor, and particularly to workbenches of the type comprising a supporting structure and a work surface disposed on the structure and including vice means.
  • WO-A-8800514 there is disclosed a workbench of this type having a cut-out in one jaw of the vice means in which a cover plate may be disposed for ordinary vice and work surface usage, but which can be replaced by an insert plate adapted to carry various power tools.
  • a cover plate may be disposed for ordinary vice and work surface usage, but which can be replaced by an insert plate adapted to carry various power tools.
  • One such tool is a circular saw and in which event the workbench is transformed into a saw table.
  • Different insert plates are used for mounting different power tools.
  • EP-A-0222477 discloses a workbench comprising: a work surface disposed on a supporting structure, the work surface comprising a vice jaw member carrying a first vice jaw; and a worktable having a second complimentary vice jaw, the worktable in a working position thereof lying substantially in the same plane as the first jaw member, the said jaws facing one another and being adapted to be moved towards and away from one another in said plane by vice operating means, said worktable being provided on its underside with means for mounting at least one power tool thereon, the worktable having a tool aperture through which a working part of said at least one power tool is adapted to project to the upper side of the worktable for working on a workpiece presented to it when the worktable is returned to said working position.
  • EP-A-0391115 discloses a workbench having a pivotable worktable, adapted to receive power tools.
  • US-A-4154435 discloses a workbench having a pivotable vice jaw to enable three-point clamping of, for example, cylindrical workpieces.
  • a workbench of the type disclosed in EP-A-0222477 characterised in that said worktable is pivotable about an axis parallel to and adjacent a rear edge of said worktable, which rear edge is remote said second vice jaw and such that said worktable is pivotable from said working position to a substantially horizontal inverted position.
  • said worktable is pivotable about an axis lying parallel to the vice jaw of the worktable and spaced therefrom.
  • said vice jaw member is fixed with respect to the supporting structure and said worktable is movable by said vice operating means.
  • said vice operating means enables asymmetric separation between the vice jaws in said plane.
  • said worktable has at least two hinge means fixed thereto for pivotal connection to said support structure; which preferably comprises a collapsible frame including two spaced parallel inverted channel sections, each incorporating separate vice operating means, said vice jaw member being fixed to one end of each channel section and said hinge means being fixed to support blocks supported on said channel sections and connected to said vice operating means through a longitudinal slot in each channel section.
  • said support structure which preferably comprises a collapsible frame including two spaced parallel inverted channel sections, each incorporating separate vice operating means, said vice jaw member being fixed to one end of each channel section and said hinge means being fixed to support blocks supported on said channel sections and connected to said vice operating means through a longitudinal slot in each channel section.
  • locking means is provided to lock the worktable in said working position.
  • Said hinge means may be provided with a degree of freedom of movement to allow the worktable to move away from said vice jaw member in the plane of said working position from a first to a second disposition thereof, and in which case said locking means may comprise hook means on one of said worktable and support structure adapted, in the first of said dispositions, to engage the other of said support structure and worktable respectively to lock the worktable in said working position, and to disengage the worktable from said support structure in the second of said dispositions to allow the worktable to be pivoted away from said support structure.
  • said hinge means comprises first and second hinge parts, the first parts being of channel section and fixed to the underside of said worktable and the second part being pivoted to the first part and being secured to said support structure.
  • Said degree of freedom is preferably provided by a pivot pin secured between said hinge parts passing through and being slidable in a slot in said first part, the slot being oriented in a direction parallel to the plane of the worktable.
  • Said hook means may comprise a backwardly directed ledge on the underside of the worktable behind its complimentary vice jaw, the ledge being adapted to engage the front of said second hinge part.
  • a workbench 10 comprises a support structure 3 having a work surface mounted thereon.
  • the work surface consists of a worktable 2 and a vice jaw member 4.
  • the vice jaw member 4 is securely fixed on two inverted channel section beams 8, through support blocks 11.
  • the vice jaw member 4 is made of ply wood and has a number of holes 5 for receiving pegs 43, which serve as abutment means for the vice function of the workbench 10 as explained further below.
  • the support structure 3 comprises two parallel I-shaped elements 30, pivoted to the beams 8 and a base 37 in parallelogram formation.
  • a diagonal member 31 braces the structure and holds it in the position shown.
  • a latch mechanism (not shown) releases the diagonal member 31 and enables the structure to be folded flat.
  • Legs 38 depend from each corner of the base 37, and can be folded flush with the base for storage or to reduce the working height of the workbench 10.
  • the vice jaw member 4 and structure 3, including the beams 8, are well known and described in EP-A-0222477 and need no further description here. Indeed, it is one of the features of the present invention that a worktable according to the invention can be employed on existing workbenches having such a construction as shown and described in the aforementioned European patent.
  • the worktable 2 comprises a substantially flat sheet of steel formed as a tray with downwardly depending lips 51a-d. To the underside of the worktable 2 are fixed three channel sections forming first hinge parts 53, near the edge 51b of the worktable. In two of these parts are pivotally supported about hinge axis 54 second hinge parts 55, which, together with the first hinge parts 53 constitute hinge elements 50.
  • the second hinge parts 55 are secured by bolts 56 (see Figs. 2 and 3) through support blocks 58 to vice sockets 60 which protrude through slot 62 formed in the top of inverted channel beam 8.
  • the vice socket 60 is threaded on vice screw 64.
  • the vice screw 64 is rotatable by handle 9 (Fig. 1) causing vice socket 60 and support block 58 to slide along beam 8.
  • the first hinge parts 53 are a channel section so that they provide lateral support for the second hinge parts 55 when the vice is operated, particularly when asymmetric gripping between the vice jaws is required.
  • the reason why the hinge parts 55 are long is so as to position the hinge axis 54 of the hinge elements 50 adjacent or near to the rear edge 51b of the worktable 2. This enables the worktable to be pivoted upwardly and away from the fixed vice jaw 4 (once the tension on the vice screws 64 has been released) to give access to the underside of the worktable 2.
  • edge 51b is provided with cut-outs 57 opposite each hinge part 53 so that the worktable 2 can be pivoted over backwards to a substantially horizontal inverted position.
  • the hinge axis 54 is as far removed from the edge 51b as the vertical clearance from the beams 8 allows. This has the effect of minimising the potentially damaging leverage that the hinge parts 55 could exert on the edge 51b when the worktable is pivoted that far backwards.
  • the worktable 2 has various tool apertures such as those shown at 70,72,74 and 76, each serving to receive the working part of a different power tool.
  • aperture 70 is a long slot adapted to receive the blade of a circular saw.
  • Numerous other holes 80 are provided around the worktable 2 to enable a power tool to be secured to the underside of the power table.
  • the worktable 2 includes, particularly for when a circular saw is employed, a rip fence 82 and saw guard 84.
  • the rip fence 82 comprises two L-sections 86, 88 fixed together in a T.
  • the long section 86 forms the guide while the section 88 is securable to the edge 51d of the worktable 2 by a screw 90 passing through a slot 92 (see Fig. 1) in the edge 51d.
  • a screw 90 passing through a slot 92 (see Fig. 1) in the edge 51d.
  • the position of the fence guide 86 is adjustable for cuts of different widths of material fed to saw blade 90.
  • the saw guard 84 consists of a box 92 and a pivotable support 94 retained by clip 96 disposed on the underside of the worktable 2 adjacent its rear edge 51b.
  • the rear edge 51b has a cut-out 98 through which the guard support 94 passes.
  • Hole 72 is adapted for a jig saw, hole 76 for a router (neither shown), while hole 74 is to receive the chuck of a drill (also not shown).
  • the tools are secured in a working position in the worktable by various means as may be convenient.
  • collars are available for the attachment of drills to various apparatus and the same means can be employed here.
  • Clips as described further below, may be provided, and these enable a wide variety of different makes of tools, which, in the case of circular saws and jigsaws, invariably have a shoe plate by means of which they may be secured to the worktable.
  • one of the features of the present invention is that the tools which it might be desired to employ in the worktable 2 can be fitted with the worktable in a horizontal inverted position. This considerably facilitates attachment of the power tool to the worktable. Subsequently the worktable can be pivoted down to the position shown in Figs. 2 and 3 once the tools are secured in place and are to be employed.
  • the weight of the tools (and the material being worked on) will normally be adequate to hold the worktable in its working position, but added security call be achieved simply by tightening the vice jaws 51a, 4 against each other. This tensions and tightens the hinge elements 50, as well as clamping the edge 51a of the worktable between hinge part 55 (63) and the vice jaw 4.
  • the third hinge part 53 is provided so that the worktable 2 can be used on workbenches of different configuration to that shown in Fig. 1; that is to say, on workbenches having beams 8 with a smaller separation between them than that of Fig 1. Also it should be noted that the worktable 2 is provided with holes 5 at various locations adapted to receive further pegs 43 enabling objects to be clamped on the workbench 10 which are wider than the maximum separation between the vice jaws 51a, 4.
  • the holes 5 are supported by sleeves 6 which prevent pegs inserted into them from twisting out of alignment when force is applied to them by all article gripped between those pegs and opposing pegs 43 in the vice member 4.
  • the worktable tray may be stiffened by indentations such as those shown at 99. Also, the various holes 80 will be counter-sunk by indentation of the tray 2 so that the heads of bolts employed to hold tools supported underneath the worktable 2 will not stand proud of its surface.
  • the plate 71 is first located on the indentations 99 and countersunk holes 80.
  • the tool for example circular saw 100, Fig. 5
  • the tool is then placed on top with its blade 104 protruding through the relevant aperture 70,70'.
  • the saw 100 has a shoe 102 which rests on the tops of the indentations 99' and is held in that position by clips 105 which simply comprise an arcuate member 106 with a central slot 108 for a screw 110 which, is seated in an adjacent hole 80 in the worktable 2 and secured by a thumb-screw 112.
  • the clip 106 deforms slightly on tightening of thumb-screw 112 to grip firmly the shoe plate 102.
  • At least two and preferably at least three of such clips 106 are employed to secure the tool 100 in place.
  • a similar arrangement is feasible with a jigsaw as regards aperture pair 72,72'.
  • a similar arrangement may be provided for a router as regards aperture 76 in the worktable, although nothing further in that respect is required for the drill aperture 74.
  • the whole chuck of the drill protrudes through the aperture 74 so there is no danger of rotating tool bits contacting the worktable.
  • the fixed vice member 4 is the vice member which is movable with respect to the supporting structure 3 by the vice operating means 9.
  • the slots 62 in the beams 8 may be replaced by a line of keyhole slots in each beam as shown in EP-A-0222477.
  • the hinge parts 55 are then fixed to the support blocks 58 which are each provided with a downwardly projecting lug adapted to engage a keyhole slot in each beam. Which keyhole slot is selected depends on the gap required between the jaw members.
  • the hinge means 50 comprises first hinge part 53' secured to the underside of the worktable 2, for example by spot welding, and second hinge part 55, which is secured to said support block 58.
  • a stud and bolt combination 54 secures the two hinge parts together and forms a pivot pin between them.
  • the embodiment of Figure 6 provides a backwardly turned ledge or hook means 120 on the bottom of face 51a of the worktable 2. This serves to hook under the front edge 63 of the second hinge part which here protrudes beyond the front edge of the support block 58. By this means the worktable 2 is prevented from pivoting upwardly which it might tend to do under certain stresses by the effect referred to as cam-out. Although this effect is already countered to some extent by the back of face 51a being pressed against front edge 63 of the hinge part 55, this on its own will not always prevent cam-out. However, the provision of said hook means 120 does serve this purpose.
  • the whole worktable may be shifted leftwardly (in Figure 6) to move the pill 54 to the right end 124 of slot 122.
  • the ledge 120 clears the second hinge part 55 and the worktable can pivot upwardly.
