Definitions

  • This invention relates to workbenches and has particular reference to portable workbenches especially to portable workbenches that are also collapsible to enable them to be carried by the user from one site to another.
  • US-A-4,061,323 also discloses a construction in which the jaw members are mounted on a support structure and the rear vice jaw member is adjustable in position relatively to the front vice jaw member by removing it from the support structure and replacing it in a different position.
  • the rear vice jaw member has several preset positions in which it can be located. That feature increases the range of article sizes that can be clamped between the jaws.
  • US-A-4,069,849 discloses a portable, collapsible workbench with front and rear elongate vice jaw members which are used to clamp between them a fence member including a mounting for a router.
  • This construction relies on both the jaw members to clamp the fence member. Consequently, because of the very limited extent to which the jaw members can be opened up, fence members of a small width only can be accommodated between the jaw members. That restricts the size of the available work surface to a relatively small area.
  • US-A-4 415 149 discloses a portable collapsible workbench with a surface provided by upper surfaces of two beams one of which is fixed and the other of which is movable to a finite number or predetermined positions.
  • a vice structure is mounted on top of the beams.
  • a board having a furring strip may be positioned over the two beams with the strip located in the space between the two beams.
  • a method of adapting a workbench comprising two elongate vice jaw members whose upper surfaces define work surfaces and a support structure upon which the vice jaw members being movable along the support structure towards and away from the other vice jaw member which is removable from the support structure, the method including the step of removing the removable vice jaw member from the support structure, characterised in that the method further includes the steps of removing the removable vice jaw member from the support structure by sliding it on the support structure towards the movable vice jaw member to a position at which it is freely separable from the support structure by removing it in a direction transverse to the upper surfaces of the jaw members, replacing the removed vice jaw member by a bench top member carrying a power tool, with parts of the bench top member engaging parts of the support structure, with an upper surface of the bench top member providing a work surface and with the power tool mounted on the bench top member, and moving the movable vice jaw member along the support structure into engagement with the bench top member and thereby clamping the bench top member firmly in place.
  • the portable, collapsible workbench shown in Fig. 1 is of a construction generally similar to that of the workbench described in GB-A-1,471,118 except that in the latter the front vice jaw member is fixed permanently relatively to the frame of the workbench and the rear vice jaw member is movable towards and away from the front jaw member whereas in the embodiment shown in Fig. 1, the rear jaw member is removable from the frame and the front jaw member is movable towards and away from the rear jaw member.
  • the workbench shown in Fig. 1 also embodies the dual height feature described in GB-A-1,471,118.
  • the workbench shown in Fig. 1 comprises two spaced, parallel support members 1, 2 that are mounted upon the base 3 of the workbench.
  • Each support is of generally channel shaped configuration and mounted between the front ends of the members 1, 2 is the front vice jaw member 4.
  • the member 4 is of elongate rectangular form and extends for the full width of the workbench, with its upper surface defining a work surface.
  • the member 4 is of a laminated wood construction and has holes 5 through it at spaced sites over its surface. The purpose of the holes 5 will be described below. Additionally, the clamping edge (the upper edge as seen in Fig. 2) has a shallow groove along it from side to side.
  • elongate slots (not shown) through which extend slider members (not shown) on the undersurface of the front jaw member 4.
  • the slider members are shaped to provide guide surfaces that coact with the sides of the elongate slots to guide the jaw member 4 during movement.
  • the slider members also have threaded bores through which the threaded rods 6, 7 extend.
  • the slider members are attached to the jaw member 4 by single point attachments, for example screws or bolts that permit limited pivotal movement of the jaw member 4 with respect to the rods 6, 7.
  • Each of the upper surfaces 10 of each support member 1, 2 also has along its length a series of spaced 'keyhole' shaped holes 11 and those form attachment points for a rear jaw member 12.
  • All the holes 11 and 11A are of generally similar key-hole shape having larger sized lower aperture 20 and narrower slot shaped upper aperture 21. However, the holes 11A have both a smaller aperture 20 and a shorter slot-shaped aperture 21.
  • the rear jaw member 12 is generally similar in size and shape to jaw member 4, being of elongate rectangular form and of a laminated wood construction. Again the upper surface of the member 4 defines a work surface. Jaw member 12 also has holes 13 at spaced sites over its surface. The position of the holes 13 may correspond with those of the holes 5.
  • support blocks 14 Secured to the underneath of jaw member 12 are support blocks 14 each carrying a fitment 15 (Figs. 4, 5 and 6) that cooperates with one or other of the keyhole slots 11 to locate jaw member 12 in place.
  • the blocks 14 are located closer to the upper (as seen in Fig. 3) edge of the rear jaw member 12 than to the other edge.
  • the upper edge is the clamping edge of the jaw member 12 and has a shallow groove along it from side to side and this groove in conjunction with a similar groove in the front jaw member 4 facilitates the clamping between the vice jaw member of rounded elongate articles, for example pipes.
  • the fitment comprises a lower coned part 16 whose upper portion is hexagonal and which is joined to an upper hexagonal part 17 via a cylindrical neck part 18 of reduced size as compared with parts 16 and 17.
  • the fitment is fixed to the jaw member by a bolt 15 a that passes through the jaw member and the block 14 and into the threaded bore 19 of the fitment.
  • the block 14 has a recess on its lower face that accommodates the upper hexagonal part 17.
  • the rear jaw member 12 is located upon the support members 1, 2 by engaging the fitments 15 in selected ones of the keyhole shaped holes 11. Fitments 15 are engaged in the holes 11 by entering the coned parts 16 through the larger sized apertures 20 of the holes 4 and then sliding the jaw member 12 rearwardly so that the neck part 18 moves into the slot-shaped apertures 21 of the holes, the coned parts 16 lying beneath the upper surface 16 of the support members 1, 2 and the hexagonal parts 17 lying above the upper surface.
  • the assembly then forms a vice with elongate jaw members 4, 12 of which the former is movable towards and away from the latter by rotating the handles 9.
  • the maximum outside diameter of the coned parts 16 is such that they can readily be entered through the apertures 20 of the holes 11 but not through the aperture parts 20 of the holes 11A. That prevents a user locating the rear jaw member 12 at the rear ends of the support members 1, 2 at which position there would be inadequate support for the blocks 14 of the member 12.
  • Jaw member 4 may be moved in a parallel orientation with respect to jaw member 12 by equal rotation of the handles 9. However, by independent rotation of the handles 9, the jaw member 4 can be inclined with respect to jaw member 12. This inclination is permitted by the single point attachment of the sliders and the degree of inclination is limited only by the limits of movement of the sliders along the slots.
  • the workbench may be adapted by removing the rear jaw member 12 by first sliding the member 12 towards the jaw member 4 and then lifting the jaw member away from the support members 1, 2, and replacing the jaw members 12 by a bench top member carrying a power tool : for example the bench top member may carry a drill stand, a belt sander, or a planer. Another possibility is to replace the jaw member 12 by a bench top of larger surface area.
  • FIG. 7 A typical bench top 22 of larger surface area is shown in Fig. 7.
  • the top is of rectangular form and may be of laminated wood construction.
  • To the undersurface of the top 22 adjacent each side thereof are pairs of fixed blocks similar to block 14, each carrying a fitment similar to fitment 15.
  • four such blocks and fitments are used, the spacing between the fitments on the blocks of a pair of blocks on the same side of the undersurface being, as can be seen from Fig. 7, equal to that between hole 11A and the lowermost of the three lower holes 11.
  • each block of a pair are sized differently as regards the outside diameter of the coned parts 16.
  • Blocks 14A nearest the lower (as seen in Fig. 7) edge of the bench top 22 have fitments 15 identical in size with those of the rear jaw member 12 whilst the blocks 14B adjacent the other upper edge have fitments 15 whose coned parts 16 are of a smaller outside diameter to pass through the smaller apertures 20 of the holes 11A.
  • top 22 can be located on the support structure in one position only. That one position is selected to ensure maximum support for the top 22 by the support structure and by the base 3 to give stability to the workbench.
  • the bench top 22 is placed on the supports 1 and 2 so that the fitments engage keyholes 11A and the immediately adjacent holes 11 in the manner described above and the user by rotating handles 9 moves the front jaw member 4 towards the bench top to move the cylindrical neck parts 18 into the slots 21 of the holes and thereby clamp the bench top 22 firmly in place.
  • the removable rear jaw member 12 may also be replaced by a saw and router table 23 shown in perspective view in Fig. 8.
  • the table 23 may be of a laminated wood construction but is preferably moulded from a suitable plastics material, for example high impact polystyrene, and has an upper surface on which is mounted a rip fence 24 movable across the surface of the table with respect to a transverse slot 25 though which projects the blade (not shown) of a circular saw when secured to the underneath surface of the table. Adjacent the slot 25 is a round hole 26 for the reception of the shaft and cutter of a router when secured to the undersurface of the table.
  • a suitable plastics material for example high impact polystyrene
  • the table 23 also has holes 27 at other sites for the reception of other fittings for example a mitre guide 28 that is secured by a bolt that passes through the guide and the hole in the table at the site selected for the guide.
  • a mitre guide 28 that is secured by a bolt that passes through the guide and the hole in the table at the site selected for the guide.
  • the table 23 has blocks 14A, 14B and fitments 15 similar to blocks 14A, 14B and fitments 15 referred to above in connection with Fig. 7.
  • the saw/router table is secured to the workbench by first removing the rear jaw member 12 and then engaging the fitments on the undersurface of the table in the holes 11A and in the lowermost of the holes 11 in the manner described above and then operating the handles 9 to move the front jaw member 4 into clamping engagement with the table 23. During such clamping engagement, there may be some movement of the table 23 in the fitments as they move into position at the ends of the narrow slot-shaped apertures 21 of the holes 11. The table 23 is thus adequately and securely supported.
  • the table 23 is also adapted to receive a guard 29 for the circular saw blade and another guard (not shown) for the router cutter.
  • the bench top 22 or the table 23 can be removed from the support members 1, 2 in the same way as the rear jaw member 12.
  • the workbench preferably has a base structure that enables the bench to be readily carried by a user from one site to another but this is not essential.
  • the bench could be a static fitting in a work shop.
  • the base structure is collapsible, the bench shown in Fig. 1 having a base structure that is collapsible.
  • the structure is also of dual height.
  • the base structure 3 comprises a pair of spaced, generally H-shaped frames 30 pivotally connected to the support members 1, 2 at points 31 and 32 respectively and to lower frame members 33, 34 at points 35, 36 respectively.
  • the frame members 33, 34 extend forwardly as seen in Fig. 1 and their ends are joined by a wide surfaced step 37.
  • the construction and arrangement of the base structure 3 enables the workbench to be used in the erected position shown in Fig. 1 and to be collapsed to a folded condition in which the frames 30 lie parallel and close to the lower frame members 33, 34 with the jaw members 4, 12 and their support members 1, 2 lying in a plane parallel to that containing the frame 30. Catches not shown are provided to lock the base structure in its erected condition and these must be released before the structure can be collapsed.
  • the lower frame members 33, 34 also have four pivotally attached legs 38 at the front and rear corners. Each of the legs 38 is movable between an outwardly folded position as shown in Fig. 1 and an inwardly folded, inoperative position. In the Fig. 1 position, the bench rests upon rubber feet 39 on the lower ends of the legs 38 and the bench is in its higher position.
  • a spring clip (not shown) is associated with each leg 38 to retain the leg in its outwardly folded position and in its inwardly-folded position, the clip being deflected as the leg is moved from one position to the other.
  • the support members 1, 2 may have one series of spaced holes for use only with the removable rear jaw member and another set for use only with the bench top and a saw/router table.
  • the upper surfaces of the vice jaw members 4, 12 may carry markings including a protractor 41, a ruler 42.
  • Fig. 1 shows four such blocks 43 located at the corners of the vice jaw members as shown.
  • the blocks when in those positions can be used to clamp articles in position by rotating handles 9 to move the front jaw member 4 towards rear jaw member 12.
  • the position of rear jaw member 12 is selected according to the front-to-back dimension of the article to be clamped by selecting the appropriate ones of the holes 11 to be used to locate jaw member 12.
