Workbench and mountable implements

BACKGROUND OF THE INVENTION
The present invention relates to workbenches and associated implements such as vises, clamps, brackets, stops and tool troughs which may be attached to a workbench, and in particular to a workbench wherein the implements may be removably mounted to the workbench in many different locations without requiring any holes, slots, or mortises to be cut into the working surface of the bench.
Workbenches generally include a work top having a work surface which is supported by a base structure. To provide and maintain a good work surface, the work surface must be kept flat, smooth and imperforate. Prior workbenches and the implements used in connection with the workbenches have required that the implements be attached to the work top thereby impairing the condition of the work surface. Some implements such as the clamp shown in U.S. Pat. No. 14,522 require that the clamp be screwed directly into the work top. The implements and work tops shown in U.S. Pat. Nos. 2,661,783; 2,764,195 and 2,888,052 require that the implements be mounted or attached to the work top through the use of countersunk recesses or bores which extend through the work top. The implements and work tops shown in U.S. Pat. Nos. 1,093,554; 1,159,199; 4,413,819 and 4,470,586 require that the implements be attached to the work top through the use of a slot which extends through the work top and the work surface. In addition, to further preserve the condition of the work surface, the work surface should not be used as a back-up for drilling holes or for chopping. Neither should jigs or other fixtures, which are often used in repetitive operations, be nailed or screwed to the work top.
As the particular operations to be performed in connection with a workbench will vary from project to project, it is also important that the various types of implements used with the bench be easily mounted to the bench in various locations as desired. The present invention overcomes these problems and provides a workbench to which various useful implements may be mounted in a variety of locations without requiring direct connection to the work top, thereby preserving the condition of the work surface.
SUMMARY OF THE INVENTION
The present invention provides a workbench having a work top, a base structure and a variety of implements such as clamps, vises, and brackets for use in connection with the workbench. The top of the workbench is supported above the floor by the base structure. The base includes a stand and frame. The frame is attached to the bottom of the work top and extends along the perimeter of the work top. The frame includes a plurality of uniformly spaced apertures. The apertures provide attachment points for mounting the various implements to the workbench. The implements may be mounted to the workbench anywhere around the perimeter of the workbench as dictated by the spacing of the apertures. The implements used in connection with the workbench such as vises, clamps and brackets include apertures or studs which correspond to the spacing of the apertures in the frame. The workbench implements may thereby be removably mounted to the workbench in a variety of positions without requiring any direct connection to the work surface of the bench top.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The workbench 10 shown in FIG. 1 is resting upon a floor 12. The workbench 10 includes a base 14 having a frame 16 and a stand 15. The stand 15 includes four legs 18. Each leg 18 includes a first flange 20 and a second flange 22 which extend between a first end 24 and a second end 26. The legs 18 are preferably made from 1/4.times.4.times.4 structural steel angles, however other sizes and different materials may be used as desired. A base plate 28 is attached to the second end 26 of each leg 18. As shown in FIG. 4, each base plate 28 may be fastened to the floor 12 by a fastener 30. As shown in FIG. 5, an elastomeric pad 32 may alternatively be placed between the base plate 28 and the floor 12 if it is not desired to bolt the base plate 28 to the floor 12. As shown in FIG. 1 and 2, the legs 18 are preferably tapered inwardly from the first end 24 to the second end 26.
The frame 16 includes a front rail 34, a back rail 36, a right side rail 38 and a left side rail 40 which are connected end-to-end in the general shape of a rectangle having four corners 41 as shown in FIG. 3. Each rail 34-40, as shown in FIG. 6, includes a vertical leg 42 having a toe 44 and a horizontal leg 46. The rails 34-40 are preferably 3/8.times.31/2.times.31/2 structural steel angles, however other sizes and different materials may be used as desired. A crossbar 48 is attached to the frame 16 between the back rail 36 and the front rail 34. The crossbar 48 laterally braces and stiffens the front rail 34 and the back rail 36. The crossbar 48 is preferably a 3/16.times.2.times.3 structural steel angle, however other sizes and different materials may be used as desired. The crossbar 48 includes a plurality of apertures 50 in a horizontal leg 52. The horizontal leg 52 of the crossbar 48 is co-planar with the horizontal legs 46 of the frame 16.
The first ends 24 of the legs 18 are preferably welded to the toes 44 of the vertical legs 42 of the rails 34-40 at each corner 41 of the frame 16. However, as shown in FIG. 8 the legs 18 may be bolted to the frame 16 such that they are removable when desired. As shown in FIGS. 8 and 9, an angle 54 may be welded to the interior of the vertical leg 42 of the frame 16 at each corner 41 to enable each leg 18 to be removably fastened to the frame 16. The angle 54 extends a distance below the toe 44 such that the first and second flanges 20 and 22 of each leg 18 may be fastened to the angle 54. A shim 55 is located between each flange 20 and 22 and the angle 54 to provide clearance between the heel of angle 54 and the fillet of the leg 18.
As shown in FIGS. 1 and 2, each rail 34-40 of the frame 16 includes a plurality of upper apertures 56 which are equally spaced horizontally from one another by a distance X. Each rail 34-40 of the frame 16 also includes a plurality of lower apertures 58 which are also equally spaced horizontally from one another by a distance X. Each aperture 58 is additionally spaced vertically below a respective upper aperture 56 by a distance Y. The distance X is preferably 53/4 inches and the distance Y is preferably 11/2 inches although different distances may be used as desired. The end of each rail 34-40 additionally includes an aperture 60 and an aperture 62 which is spaced horizontally apart from the aperture 60 the distance Y. Each flange 20 and 22 of each leg 18 also includes an aperture 64, and an aperture 66 which is horizontally spaced from the aperture 64 by the distance Y. The aperture 64 in the leg 18 is vertically below the aperture 60 by a distance of two times X (2X) and the aperture 66 is located vertically below the aperture 62 by the distance 2X. Each upper aperture 56 and its vertically adjacent lower aperture 58 constitute a place of attachment on the frame 16. Each aperture 60 and its adjacent aperture 62 also constitute a point of attachment on the frame 16 as does each aperture 64 and its adjacent aperture 66. The toes 44 which extend along each rail 34-40 between the legs 18 constitute a substantially continuous attachable edge for the attachment of implements on the frame 16 as will be explained.
As shown in FIG. 3, the horizontal leg 46 of each rail 34-40 of the frame 16 includes a plurality of inner apertures 68 and a plurality of outer apertures 70 which are spaced apart from a respective inner aperture 68 by the distance Y. As shown in FIGS. 3 and 7, a plurality of gusset plates 72 are attached between the vertical leg 42 and the horizontal leg 46 of each rail 34-40 of the frame 16 to stiffen the rails 34-40. The gusset plates 72 are spaced so as not to interfere with any of the apertures in the frame 16.
The workbench 10 also includes a work top panel 74 as shown in FIGS. 1 and 2. The work top panel 74 includes an upper work surface 76, a lower attachment surface 78 and a peripheral edge 80 which extends around the perimeter of the top panel 74 between the work surface 76 and the attachment surface 78. The work top panel 74 is located adjacent to the horizontal legs 46 of the frame 16 such that the peripheral edge 80 of the work top 74 is flush with the vertical legs 42 of the frame 16 as shown in FIG. 6. The work top panel 74 is removably fastened to the frame 16 by screws 82 which extend through the apertures 68 and 70 of the horizontal leg 46 and into the attachment surface 80 of the top panel 74. The top panel is preferably 30 inches wide by 72 inches long, with the work surface 76 being approximately 33 inches above the floor 12. These dimensions may be varied as desired. The work top panel 74 is preferably made of 21/4 inch thick hard maple, however other dimensions and other materials may be used as desired. The work surface 76 and the peripheral edge 80 of the work top panel 74 should be smooth, flat and imperforate. The attachment surface 78 is the underside of the work top panel 74 and is not used as a work surface.
Various implements 88 may be removably mounted to the base 14 by attachment through any one of the apertures 56, 58, 60, 62, 64 or 66. The uniform spacing of the pairs of apertures 56 and 58 from adjacent pairs of apertures 56 and 58 by the distance X allows the implements 88 to be mounted to the base 14 at any desired location as dictated by the spacing distance X. Various implements 88 may also be removably mounted to the base 14 by attachment to any point along the toe 44 of the frame 16. The mounting of the implements 88 to the workbench 10 is made to the base 14 of the workbench 10 independently from the top panel 74. The mounting of the implements 88 to the base 14 does not require that the top panel 74 or its work surface 76 be cut, drilled or otherwise perforated or impaired. Each implement 88 may be mounted to the base 14 in a variety of different locations as desired for use with the workbench 10 without harming or directly attaching to the work top panel 74. More than one implement 88, or a variety of different types of implements 88, may be mounted to the base 14 at one time for use with the workbench 10, all independently of the work top panel 74.
One type of implement 88A which may be mounted to the base 14 of the workbench 10 is a vise 90 as shown in FIGS. 10 through 22. The vise 90 includes a movable jaw 92 and a fixed jaw 94. The movable jaw 92 includes a plate 96 and a top plate 98 attached thereto and extending perpendicular from the top edge of the plate 96. A side plate 100 is attached to and extends perpendicularly from each side of the plate 96. The plate 96 includes four apertures 102 and an aperture 104. The top plate 98 includes two apertures 106 and two apertures 108. A sleeve 110 is attached to the plate 96 such that the sleeve 110 is concentric with the aperture 104. A rod 114 having a cylindrical portion 116 attached to a threaded portion 118 by a spherical portion 120 extends through the aperture 104 such that the spherical portion 120 is located within the sleeve 110. A spherical bushing 122 is located within the sleeve 110 adjacent to the spherical portion 120 to provide an antifriction connection between the rod 114 and the moveable jaw 92. The spherical bushing 122 is preferably an aluminum bronze bushing. The rod 114 preferably has a one inch diameter threaded portion 118 and a 17/8 inch diameter spherical portion 120. A cover plate 124 having an aperture 126 is located adjacent to the sleeve 110 and is fastened thereto by bolts 128 such that the cylindrical portion 116 extends through the aperture 126. A handle 130 is slidably attached to the cylindrical portion 116 of the rod 114.
The moveable jaw 92 also includes two sleeves 132, as shown in FIGS. 12 and 15, which are connected to the plate 96 and to the sleeve 110 at opposite sides thereof. A guide tube 134 having a first end 136 and a second end 138 extends through each sleeve 132 with the first end 136 affixed within the sleeve 132. The second end 138 of each guide tube 134 includes a pair of apertures 140 through which a cotter pin 144 may be placed. A preferred guide tube 134 is approximately 11/2 inches in outer diameter. A tube 146 extends between each sleeve 132 and the top plate 98. Each tube 146 includes a hollow chamber 148 and a vertical slot 150. The tubes 146 are located such that the chambers 148 align with respective apertures 108 in the top plate 98. Each tube 146 also includes two diametrically opposed apertures 152.
The fixed jaw 94, as shown in FIGS. 13-15, includes a plate 154 having a top plate 156 attached to and extending perpendicularly from the top edge of the top plate 156 and a side plate 158 attached at each side of the plate 154 and extending perpendicularly thereto. The plate 154 includes four apertures 159 which are aligned with the apertures 102 in plate 96. An ear 160 is attached to each side plate 158. Each ear 160 includes two apertures 162 which are spaced apart from one another by the distance Y to correspond to the distance Y which the apertures 56 and 58, 60 and 62, and 64 and 66 are spaced apart from one another thereby allowing the apertures 162 to align with the apertures in the base 14. The apertures 162 in one ear 160 are spaced apart from the apertures 162 in the other ear 160 by a distance of 2X to correspond to the distance between the apertures 60 and 64, and 62 and 66 in the base 14 to allow the vise 90 to be vertically mounted at any corner 41 as shown in FIG. 11 and to correspond to any pair of apertures 56 and 58 which are spaced apart the distance 2X to allow the vise 90 to be horizontally mounted to the frame 16 as shown in FIG. 10 in a plurality of locations. A housing 164 is attached to the bottom center portion of the plate 154. The housing 164 includes an aperture 166 and two diametrically opposed slots 168. A cover plate 170, having an aperture 172, is removably fastened to the housing 164 by bolts 174. A trunnion nut 176 having two extending trunnions 178 and a threaded aperture 180, as shown in FIGS. 14 and 19, is located within the housing 164 with the trunnions 178 extending into respective slots 168 such that the trunnion nut 176 is able to pivot about the trunnions 178. The threaded aperture 180 of the trunnion nut 176 is adapted to threadably engage the threaded portion 118 of the rod 114. The nut 176 is preferably an aluminum bronze nut. The fixed jaw 94 also includes two sleeves 182 which are attached to the plate 154 at either side of the housing 164 and in alignment with the sleeves 132 of the movable jaw 92. Each sleeve 182 includes a circular bore 184. A bushing 186 is located at each end of each sleeve 182 within the circular bore 184. The bushings 186 are adapted to permit a guide tube 134 to slide within each sleeve 182. The bushings 186 are preferably aluminum bronze bushings. The fixed jaw 94 also includes two tubes 188 which extend between a respective sleeve 182 and the top plate 156. Each tube 188 includes a chamber 190 which is aligned with an aperture 192 in the top plate 156 as shown in FIG. 15. Each tube 188 also includes a slot 194 and a pair of diametrically opposed apertures not shown. The top plate 156 also includes a pair of apertures 196.
The appropriate rotation of the handle 130 and the rod 114 will draw the rod 114 through the trunnion nut 176 thereby pulling the movable jaw 92 towards the fixed jaw 94. A workpiece may be positioned between the jaws 92 and 94 such that as the moveable jaw 92 is pulled towards the fixed jaw 94, the workpiece will become clamped between the jaws 92 and 94. Further rotation of the rod 114 will apply additional clamping force to the workpiece. Opposite rotation of the rod 114 will move the moveable jaw 92 away from the fixed jaw 94 thereby decreasing the clamping force on the workpiece.
A dog 198, as shown in FIG. 21, includes an upper end 200 and a lower end 202 and is preferably cylindrical in shape. The dog 198 includes a threaded aperture 204 extending downwardly from the upper end 200 along the longitudinal axis of the dog 198. A bore 206 extends through the lower end 202 of the dog 198 perpendicular to the longitudinal axis of the dog 198. A spring 208 is located within the bore 206 and a spherical ball 210 is located at each end of the spring 208 such that the spring 208 biases the spherical balls 210 outwardly from the dog 198. The dog 198 also includes a threaded aperture 212 which extends into the dog 198 in a direction perpendicular to the longitudinal axis of the dog 198. A dog 198 is located within each of the tubes 146 and 188. The dogs 198 which are located within the tubes 146 have a stem 214 attached to the threaded aperture 212 and extending horizontally through the slot 150 as best shown in FIG. 15. The dogs 198 which are located within the tubes 146 may be raised or lowered by grasping the stem 214 and moving the stem 214 upwardly or downwardly within the slot 150. When the dogs 198 within the tubes 146 are in their lowered positions, the upper end 200 of the dogs 198 will be flush with the top plate 98. When the dogs 198 within the tubes 146 are moved to their raised positions, the dogs 198 will extend through the apertures 108 in the top plate 98 and the spring 208 will bias the spherical balls 210 into the apertures 152 of the tubes 146 to releasably hold the dogs 198 in the raised position. Two dogs 198 are also respectively located within the tubes 188 of the fixed jaw 94 as shown in FIG. 15. A screw 216 is threadably fastened to the threaded aperture 212 and extends outwardly through the slot 194 of the tube 188 to prevent rotation of the dogs 198 within the tubes 188. The dogs 198 in the fixed jaw 94 may be moved to their raised position by threadably inserting a tool 218, having a threaded portion 220 as shown in FIG. 20, into the threaded aperture 204 of the dogs 198 and pulling the dogs 198 upward. Once the dogs 198 in the fixed jaw 94 have been raised, the tool 218 may be removed and the spring 208 will bias the spherical balls 210 into the apertures 196 of the tubes 188 to releasably hold the dogs 198 in the raised position. The dogs 198 in the fixed jaw 94 may be moved to their lowered position by applying a downward force on the dogs 198. When the dogs 198 are in their lowered positions, the dogs 198 are inoperative and located out of the way. When the dogs 198 are raised, a workpiece may be clamped between the dogs 198 located in the respective jaws 92 and 94. The dogs 198 may also serve as stops to secure a workpiece in position.
A liner 221 having a vertical plate 222 and a horizontal plate 224 as shown in FIG. 22 may be attached to both the movable jaw 92 and to the fixed jaw 94. The liners 221 provide a softer clamping surface than the plates 96 and 154 to protect a workpiece which is clamped within the vise 90 from being damaged. The vertical plate 222 includes four countersunk apertures 226 which are adapted to be fastened through the apertures 102 to the movable jaw 92 and through the aperture 159 to the fixed jaw 94. The horizontal plate 224 includes two countersunk apertures 228 which are adapted to be fastened through the apertures 106 to the movable jaw 92 and through the apertures 196 to the fixed jaw 94 as shown in FIG. 14. The plates 222 and 224 are preferably made of wood.
A block 230, as shown in FIG. 16, is substantially square and includes an aperture 232. A bar 234, as shown in FIG. 17, includes two apertures 236 and is substantially rectangular in shape. When a dog 198 is in its raised position, a block 230 may be placed on the vise 90 such that the dog 198 extends through the aperture 232 as shown in the fixed jaw 94 in FIGS. 13 and 15. The bar 234 may alternatively be placed on the vise 90 such that a pair of dogs 198 respectively extend through the apertures 236 as shown on the movable jaw 92 in FIGS. 13 and 15. The blocks 230 and the bar 234 are preferably made of wood. The blocks 230 and bars 234 are generally rectangular and therefore provide a larger bearing surface than provided just by the dogs 198. This helps to reduce the possibility that the clamping forces exerted by the dogs on the workpiece will indent or otherwise harm the workpiece.
The vise 90 may be mounted in a horizontal position, as shown in FIG. 10, to the frame 16 of the workbench 10 by fasteners 237 extending through apertures 56 and 58 or the vise 90 may be attached in a vertical position, as shown in FIG. 11, to the frame 16 and to a leg 18 of the workbench 10 by fasteners 237 extending through apertures 60-66. The vise 90 may be mounted vertically to any of the flanges 20 and 22 of the legs 18. When the vise 90 is mounted horizontally to the base 14, the top plates 98 and 156 are below the work surface 76 as shown in FIG. 10. The vise 90 may be mounted to the frame 16 at any pair of apertures 56 and 58 which are spaced apart by a distance 2X. The vise 90 may thereby be mounted to the base 14 in a variety of different locations for use with the workbench 10 without harming or directly attaching to the work surface 76.
The guide rods 134 of the vise 90 will support the downward loads applied to the vise and in doing so may deflect or bend downwardly. The rod 114 however is supported at one end by the pivotable trunnion nut 176 which will allow the rod 114 to pivot downwardly without causing any bending in the rod 114. The rod 114 will therefore be subject to only tensile or compressive forces and not bending forces. As a result, there will be less friction between the nut 176 and the rod 114 and less torque will need to be applied to the rod 114 to reach the desired clamping force between the jaws 92 and 94.
Another implement 88B is a beam clamp 238. The beam clamp 238 is shown in FIG. 23 attached to opposite sides of the frame 16 of the workbench 10. The beam clamp 238 is shown clamping a workpiece 240 against the work surface 76 of the work top panel 74. The beam clamp 238 includes a beam 242 having a first end 244, a second end 246, a top surface 248 and a bottom surface 250. A bore 252 extends through the beam 242, from the top surface 248 to the bottom surface 250, at the first end 244 and at the second end 246. The beam clamp 238 also includes a pair of clamping screws 254 which respectively include a threaded rod 256 extending between a first end 258 and a second end 260. A handle 262 is slidably attached to the first end 258 and a washer 264 is attached to the threaded rod 256 by welding or other means a short distance below the handle 262. A threaded rod 256 extends through each respective bore 252 such that the washer 264 will abut the top surface 248 of the beam 242. The threaded rod 256 extends through a washer 266 and a nut 268 is threadably attached to the threaded rod 256 to retain the washer 266. An anchor bracket 270, best shown in FIG. 24, includes a plate 272 having two upper apertures 274 spaced apart by a distance X and two lower apertures 276 spaced apart by a distance X. The upper apertures 274 are located above respective apertures 276 a distance Y. A mounting plate 278 having a slot 280 is attached to the plate 272.
An anchor bracket 270 is attached to opposite sides of the frame 16 as shown in FIG. 24. Each anchor bracket 270 is attached to the frame 216 by fasteners 282 which extend through the apertures 274 and 276 of the anchor bracket 270 and the apertures 56 and 58 of the frame 16. The threaded rod 256 of each clamping screw 254 is located in a respective slot 280 of the anchor bracket 270.
