Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to a versatile workbench frame for woodworking applications.

More particularly, the present invention relates to a versatile and portable workbench frame that allows precision woodworking of relatively large objects or workpieces to be performed safely and easily. Typical workbench frames for precision woodworking are subject to price and space constraints due to their use by small-scale woodworkers and do-it-yourselfers, but are generally suitable for relatively large workpieces, e.g.
Unable to handle panels or doors that reach 240 ca.

Known workbench frames generally have a horizontal top worktable for supporting a workpiece and are broadly divided into two types of construction: '1} Since the selected tool is mounted below the work table, it is difficult to replace the tool.

Furthermore, the small size of the work table and workpiece guide precludes adequate and safe support of large workpieces. Although such workbench frames can be used with additional support members, knowledge, effort, and materials are required to manufacture such support members. Workbench frames of this type are already difficult to carry, but this difficulty is further increased by the additional support members. [2} A single cantilever beam is mounted above the midsection of the top table and passes through a single telescoping column mounted midway through the trailing edge of the table.

A selected power tool, such as a radius arm mirror motor and carriage assembly, is slidably mounted to the cantilever beam to perform various woodworking and other tasks. Similar to {11 above, this type of workbench frame also cannot safely and accurately support or guide large materials. Furthermore, the installation of additional support members is difficult. Firstly,
The telescoping column must be centered at the trailing edge of the top table, where the large workpiece and column will interfere. Second, the cantilever beam is supported at only one end and cannot be extended to a desired length. Despite its small dimensions, this type of workbench frame is not easily portable. Industrial workbench frames allow handling of large workpieces.

However, such workbench frames are expensive, and their large size and space occupancy make them unsuitable for small-scale contractors and amateurs. Moreover, it is not constructed to be portable. BACKGROUND OF THE INVENTION Stands, cradles, benches, etc. are known which are adapted to carry selected different tools for carrying out various woodworking tasks.

Generally, such stands can only be attached to one power tool at a time. To perform different operations, it is necessary to remove a tool and install another. Accordingly, such stands require the user to release, lift, transport, lower into position, and adjust the typically relatively heavy components and adapters. These parts occupy space, are scattered around the work site, and are difficult to find, making it difficult for users to move them. A primary object of the present invention is to provide a portable workbench frame that allows precision woodworking to be performed on large workpieces.

Another object of the present invention is to provide a workbench frame on which a large number of commonly used tools can be mounted and which can be easily used without interfering with other tools.

Another object of the present invention is to provide a workbench frame that is easy to carry, inexpensive to manufacture, and available to small scale traders and amateurs.

The workbench frame according to the present invention includes a large frame main body having a substantially rectangular shape, two pairs of foldable support members disposed at both ends of the frame main body for horizontally supporting the frame main body, and the frame main body. two columns spaced apart from each other at two corners of one longitudinal green portion of the body, the columns extending spaced apart and forwardly above the frame body; a member, further comprising an elongated transverse beam attached to the cantilever member, the beam being operable to attach a selected tool, and the column attaching the beam to the frame body. It is characterized in that it can be selectively adjusted upward or downward at the same time. below,
Embodiments of the present invention shown in the drawings will be described in detail.

The workbench frame 10 according to the present invention has a rectangular frame body 1
1, and this main body has four steel C-shaped sections 12, 1.
3, 14 and 15.

Both of these profiles have outwardly directed openings. The frame body 11 has two pairs of foldable legs 16,1.
Supported by 7. These legs 16, 17 are pivotally connected to the four corners of the frame body 11, and are arranged in a folded position located on the underside of the frame body and in a horizontal position as shown in FIGS. 1 and 2. It is configured to be selectively movable to either an upright position for support. Reinforcements 18 may be provided on the end profiles 14 and 15 to enable the legs to be held in an upright position, and the legs 16 and 17 may be provided with reinforcement villages 19a and 19b. Telescoping columns 20 and 21 are provided at the two rear corners of the frame body 11.

The columns 20 and 21 are provided with bases 22 and 23 which are secured to the end profiles 14 and 15 and the two support members 24 and 25 by fastening elements such as bolts 26. Inner tubular member 2 for each column 20 or 21
7 and an outer tubular section 2 slidably arranged on the outside thereof.
8. In the illustrated embodiment, a vertical worm shaft 29 is mounted on the base to allow the outer tubular member to slide relative to the inner tubular member, and a gear 30 is rotatable by rotation by a handle 31. Place it in The handle 31 is attached to a connecting rod 32 which extends from one end of the frame body to the other. The gears 30 of both columns 20 and 21 are connected by a connecting rod 32,
Rotation of the handle 31 causes the outer tubular members of the two columns to move simultaneously relative to the corresponding inner tubular members. Handles 31 are provided at both ends of the connecting rod so that both columns can be operated by rotating one of them.
Connecting the upper end of the outer tubular member 28 to the upper end of the sliding tube 33,
A screw element 34 is supported at the lower end of this sliding tube. This screw element 34 is engaged with the worm shaft 29 so that rotation of the worm shaft 29 is transmitted as a concentric movement of the sliding tube and the outer tubular member relative to the fixed inner tubular member. Of course, it is also possible to use different types of telescoping devices operated by pneumatic or electrical means for the same purpose as the manual device shown. An inverted L-shaped girder 35 is integrally provided on the outer tubular member 28 of the telescopic columns 20 and 21.

This girder 35 is provided with a horizontal portion 36 that extends toward the front of the frame body, is spaced apart from the frame body, and reaches above the center in the depth direction. A beam 37 extending in the lateral direction of the frame body is attached to the lower side of the horizontal part 36 of both girders 35, and is placed at the free end of the horizontal part 36, so that the beam 37 is positioned above the center line in the depth direction of the frame body. let This beam 37 may be constructed by a single rectangular beam or by combining two plates 38 and 39 with a plurality of support plates 40 as shown in FIG.

Rod runners 41 and 42 are attached to the lower longitudinal edge of the beam to allow various selected woodworking power tools to be slidably mounted to the beam. If desired, the beam may be configured to engage suitable power tool mounting means via an adapter carriage, which in turn is slidably engaged with the runner. As shown in FIG. 1, a radius arm mirror or circular saw motor and carriage assembly 43 is attached to the beam. The assembly 43 is of known construction and is releasable and lockable at selected positions along the beam and settable in selected directions about a vertical axis. A rotatable rectangular work table 44 is removably mounted on the frame body, and its dimensions are large enough to be placed on the front and rear C-shaped members of the frame body 11.

The work table constitutes a rectangular upper panel 45 and a lower rectangular panel 46 fixed adjacent to each other. A central entrance 47 is formed in the center of the work table. lower panel 4
6 is fixed by bolts to an annular plate 48, which has a central opening concentric with the central opening 47 of the work table. A hollow shaft 49 is fixed to the annular plate 48, for example by welding, and extends perpendicularly downward from the annular plate 48 into rotational engagement with a bearing 50. Needless to say, the annular plate can be constituted by a flange integrally formed on the upper end of the hollow shaft. The bearing 50 is fixed between the upper extension flanges 51 of the two lateral support villages 52, and the honoring plate 53 is fixed to the lower flange of the support member 52 by bolts 54. Therefore, the work table 44 is rotatable relative to the frame body 11 around the hollow shaft 49. The hollow shaft 49 acts as a chute for discharging waste from the work table to a collection container or the floor during work such as drum sander finishing, and is used to house tools such as a shaping cutter, counterbore bit, and drum sander. It can also be used. A clamping device is provided at the lower end of the hollow shaft 49 so that the working table can be held in any angular position relative to the frame body 11.

The clamping device is constituted by a collar-shaped clamping block 55 formed with a notched end and mounted on the lower support member 52. This block is operable by a nut 56 cooperating with the threaded end of a rotating rod 57, which is connected to the front C-shaped section 12.
extends outwardly therethrough and is provided with a knob 58 at its forward end. Pointer 5 that displays the angular position of the work table
9 is attached to a spacer 60 fixed to the lower side of the front edge of the lower panel 46. The base plate 60 is rounded to have the same thickness as the annular plate 48 so that the work table 44 can be stably mounted on the front C-shaped member 12 of the frame body and on the lateral support member 52. Make it. An arcuate scale 61 is mounted on the lateral support member 52. The pointer 59 and the scale 61 are connected to a slot closure 6 formed in the front part of the work table 44, as shown in FIGS. 1 and 3.
Place it so that it can be confirmed through 2. A releasable snap stop mechanism is provided to lock the worktable in normally used angular positions between oo and 180o in 15o increments.

The snap stop mechanism includes a pin 63 which is resiliently slidably disposed within a housing 64 which is attached to the mounting plate 53. The pin 63 extends resiliently through the top closure of the housing 64 and engages a plurality of recesses 65 formed on the underside of the annular plate 48 . These recesses 65 are semicircular in the range of 150 to 1800.
Arrange at intervals. Therefore, the work table 44 is set to 00
When the pin 63 is rotated by 15 degrees within the range of 1800 degrees, the pin 63 engages the recess 65 and locks the work table 44 in that angular position. The pin 63 is connected to a tension cable 66 which can be operated by a knob 67 mounted on the front C-shaped profile 12 adjacent to the knob 58 of the clamp book 55. When the pin 63 is released from the recess 65 by pulling the cable 66, the work table 44 can be rotated to the desired angular position without being locked by the snap stop mechanism. Two transverse grooves 68 and 69 are formed in the rear edge and left green part of the working table, respectively, in which guide members 70 and 71 are mounted.

Each groove 68 or 69 is formed by an elongated L-shaped member 72 secured along the corresponding green section. This L-shaped member 72 is provided with a horizontal portion and a low rising portion. Its horizontal part is attached to the underside of the lower panel 46 of the working table and has a thickness equal to that of the annular plate 48, so that the horizontal part stabilizes the working table on the rear C-shaped profile 13 of the frame body 11. It is configured so that it also acts as a sub-baser to make it a battle layer. At least two sets of screws 73 are placed in the raised portions of L-shaped member 72 to secure guide villages 70 and 71 within corresponding grooves 68 and 69. at least one auxiliary extension outrigger 7
4 is removably attached to the front and rear C-shaped sections 12 and 13 to form an extension of the work table 44 for supporting relatively long workpieces, so that the panel is secured by the work table and outriggers. Supported.

The outrigger 74 is provided with a member 75 having an elongated rectangular U-shaped cross section which may be made of a lightweight metal alloy.

A leg bracket 76 is attached near the free end of the U-shaped village 75, and a leg 77 is pivotally attached to this bracket 76. This leg can pivot to the vertical position shown in FIGS. 1, 2, and 6, and in this position, by contacting the vertical support plate 78 of the bracket 76, the leg can be stably held in the vertical position. Configure. An adjustable swivel support member 79 is provided at the lower end of the leg so that the upper surface of the outrigger is attached to the work table 4.
It can be adjusted to match the top surface of 4. The L-shaped member 80 is attached to the lower side of the attachment end of the U-shaped member 75. This L-shaped member is provided with a horizontal plate 81 fixed to the U-shaped part 75 by welding or other methods, and a vertical plate 82 extending downward from the rear edge of the horizontal plate 81. Two mounting pins 83 are arranged so as to extend below the horizontal plate 82.

A rotatable cam 84 is attached to the vertical plate 82. This cam 84 is rotated by rotating the star-shaped handle 85. Move the outrigger 84 forward or backward C-shaped member 1
2 or 13, the C-shaped profile is configured to be held between the horizontal plate 81 and the cam 84 by engaging the pin 83 with the holding recess 86 (see FIG. 3). be able to.

When the outrigger is safely attached to the C-shaped profile by rotation of the star-shaped handle 85, the cam is attached to the frame body 1.
Press the lower side of the C-shaped section 1 tightly. To quickly and easily remove the outriggers from the frame body,
Rotate the star handle 85 to release the cam 84 from the C-shaped member, then raise the U-shaped member 75 to release the pin 83.
is released from the recess 86. Since the horizontal cross plate 87 is laterally attached to the lower side of the U-shaped member 75 and is placed slightly apart from the horizontal plate 82, the rectangular opening 88 is located between the side surface of the U-shaped member and the cross plate 87. is formed.

A U-shaped clamp member 89 is placed on the cross plate 87 and extended through the upper entrance. The clamp member is provided with a raised inner end 90 which is disposed within the U-shaped member 75. A threaded aperture 91 is formed with a raised inner end 901 to mate with a threaded rod 92, which threaded rod has a U
It is connected to a rotating wheel 93 rotatably attached to the side surface of the letter-shaped member 75. The clamp member 89 is movable by the rotation of the rotating wheel 93, and at this time, the rising outer end 94 of the clamp member cooperates with the side surface of the outrigger 74 to hold the extension of the guide member 71 along the green part of the outrigger. The configuration is such that it forms a clamp for Elastic bifurcated member 95
can be attached to the lower side of the cross plate 87. This bifurcated member 95 can be used for the purpose of holding the legs 77 of the outrigger 74 when the legs are folded for storage. The frame body 1 according to the present invention preferably has dimensions of about 6 mm x 210 mm, and in that case, the frame body can be easily transported with its legs folded in a regular-sized station wagon. be able to.

In this way, the frame body can be easily carried to the work site. The frame body of the present invention is easy to transport, which is advantageous for small-scale wood processing businesses. The reason for this is that time can be saved if the frame body can be carried to the work site, whereas if the processing equipment is not portable, the workpiece must be returned from the work site to the factory. The dimensions of the work table 44 may be approximately 60 arcs by 120 arcs.

A work table formed to such dimensions can be attached to the frame main body having dimensions of 60 pieces x 210 pieces, together with various woodworking tools. As shown in Figure 2,
The work table 44 may be disposed two columns apart on the right hand side of the frame body, and the circular saw assembly 43 may also be slidably disposed on the right hand side of the beam 37. The pair of tailstocks 96, 97 of the lathe can be slidably mounted between the circular saw assembly 43 and the other column 21, in which case one is moved by a motor 98 mounted on the underside of the frame body. to drive the tailstock. The band key 99 can be detachably attached to the left side of the front C-shaped member 12 in close proximity to the left column 21. This bandsaw can be driven by a motor 001 attached to its mounting bracket. The work table 101 of this band mirror is placed in front of the C-shaped member 1.
2 can be provided. With such an arrangement, the tool to be used is easily accessible, without the need for replacement operations such as removing the tool and installing another tool, as in known workbench frames. Furthermore, each tool does not interfere with other tools when operated, and can be used without removing other tools attached to the workbench frame. When performing linear lock pulling work using a circular saw, the tailstock of the lathe is slid to the left to enable the circular saw to slide over the entire length of the work table.

Both the circular saw and work table can be pivoted to facilitate miter, bevel or compound cuts. When cutting a relatively large workpiece, attach an appropriate number of outriggers to the frame body to support the workpiece, position the workpiece perpendicular to the workbench frame, and place the workpiece between the columns. extend across a space.

The space between the outriggers allows the user access to the workbench frame for safe control of machining the workpiece. In addition, the outriggers can be used as a base for locking guide tracks with lockable pivot points, which are used for cutting, sanding, shaping, etc. operations along a circumferential path. It should be of a variable radius type, which is necessary for such work. The motor-driven part of the circular saw can also perform tasks such as sanding and shaping using a disk or drum.

The workbench frame according to the present invention has a larger work surface than known power tool workbenches, and also allows safe and precise tools to be easily attached, making it possible to easily perform the various tasks mentioned above. shall be. In the workbench frame according to the invention, the worktable 101 of the band saw is larger than in a normal band saw, so that workpieces can be handled safely and effectively by the band saw.

Since the pair of tailstocks 96 and 97 constitute an inverted lathe on the workbench frame, an elongated chisel-shaped tool rest can be placed over the entire length of the frame body and the template can be fixed to the tool rest. A sander cylinder used for surface sanding can be attached to this inverted lathe. A pivotable attachment opening □ 102 is formed in one tailstock 96 to allow attachment of a drilling machine.

The telescoping and adjustable columns and beams allow for increased cutting capacity when drilling relatively large workpieces, as opposed to a typical drill press that has a cutting capacity of only a few inches. Also, a series of drills can be mounted on the beam 37 to enable gang drilling.The drill bits are simultaneously driven into the workpiece by simply lowering the beam.Furthermore, the tailstock of the lathe is placed in an inverted position. Although the present invention has been described in terms of a preferred embodiment, it will be appreciated that various changes may be made without departing from the spirit and scope of the invention. stomach.
