Multiple vise system

Abstract

A multiple vise system comprising at least two vise heads, each vise head comprising two jaws and a tightening screw and also comprising a supporting structure. The supporting structure is configured to support each vise head and allows the position of the vise heads to be adjusted according to at least two degrees of freedom with respect to each other. Position adjustment is achieved by means of track and slots mechanisms, swivels and telescoping poles. A number of secondary clamps are included to hold specially shaped objects such as printed circuit boards and to hold objects too large to be held by a vise head.

Description

FIELD OF THE INVENTION

Background

Vises are well known devices for holding pieces being worked on. Typically they are designed to hold a single object at one single point. A number of patents describe dual vise systems wherein the jaws are mounted on a single vise or slide on a single track. These include U.S. Pat. Nos. 5,623,757 and 6,250,620 by Durfee, U.S. Pat. No. 5,022,636 by Swann, U.S. Pat. No. 4,685,663 by Jorgensen, U.S. Pat. No. 4,529,183 by Krason et al., U.S. Pat. No. 6,896,249 by Ferrara, U.S. Pat. No. 5,374,040 by Lin, U.S. Pat. No. 5,649,694 by Buck as well as U.S. patent application 20060049566 by Bernstein.

U.S. Pat. No. 6,338,477 by Moore includes a single vise head and two screws.

These systems however, lack flexibility and are not adequate when several objects need to be held in a certain spatial relationship with each other or when a single object having a complicated shape needs to be held at more than one point. In addition, when one end of an object is clamped in a vise and cut, the object often breaks off before the cut is completed, leaving two jagged edges rather than the desired smooth, clean cut.

None of the prior art offers the utility value of this invention. Further features, aspects, and advantages of the present invention over the prior art will be more fully understood when considered with respect to the following detailed description claims and accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 illustrates a version of the invention comprising two vises capable of being positioned with two degrees of freedom from each other.

FIG. 2 provides an exploded view of FIG. 1 showing the supporting platform with two slots perpendicular to each other.

FIG. 3 illustrates a two-vise system wherein the vises are equipped with swivels and height adjustment telescoping poles.

FIG. 4 shows the two vise system with an alternate mount that include a base plate permanently bolted down, similar to current vise designs.

FIG. 5 shows a three-vise system wherein the vises are equipped with swivels and height adjustment poles.

FIG. 6 shows a three vise system holding special purpose secondary clamps specially designed to hold specially shaped objects such as printed circuit boards, or to hold objects too large to fit within the vise head.

SUMMARY OF THE INVENTION

This invention provides its user with two features that conventional vises do not have:

• • a) Two or more support points for the piece being worked on, each support point being provided by an independent vise head, each vise head comprised of two jaws and a tightening screw; and
  • b) A supporting structure for the vise head that allows the adjustment of their positions according to several degrees of freedom thereby providing unprecedented flexibility in configuration for supporting objects being worked on.

The invention comprises a multiplicity of vise heads, each vise head being attached to a common supporting platform configured to allow the position of the vise heads to be adjusted with respect to each other. The relative positions of the vise heads can vary by at lease two degrees of freedom.

In a first implementation, the supporting platform comprises two perpendicular slots that allow the vise heads to be positioned according to two linear degrees of freedom. As an option the vise heads can be rotated with respect to the supporting structure, thereby providing two additional degrees of freedom of the rotational (yaw) type.

In a second implementation, a swivel and a telescoping pole are included in the attachment between each vise head and the supporting platform. Each swivel adds two more rotational degrees of freedom (pitch and roll) and each telescoping pole adds a translational degree of freedom (elevation).

A third implementation includes three vise heads and a supporting platform equipped with three slots oriented at 120 degrees from each other, thereby allowing an object to be supported at three points or two to three objects to be supported in various positions and orientations with respect to each other.

The vise heads are also used in conjunction with secondary clamps designed to hold specially shaped objects such as printed circuit boards or to hold large objects too large to fit within the vise head.

DETAILED DESCRIPTION

This invention provides its user with the following features:

• • a) Two or more support points for the piece being worked on or cut, each support point being provided by an independent vise head, each vise head comprised of two jaws and a tightening screw; and
  • b) A supporting structure for the vise head that allows the vise heads to be positioned according to several degrees of freedom thereby providing unprecedented configuration flexibility for supporting objects being worked on.

The invention can take many forms. The particular version shown in FIG. 1 includes two vise heads 1 and a supporting platform 9 that allows the vise heads 1 to be moved and firmly positioned along two degrees of freedom with respect to each other. The relative translation of the vise heads in the XY plane is accomplished by the supporting platform 9.

The vise heads 1 are conventional: they include a base 2 and two jaws 4 and 5. Each vise base 2 is equipped with a track or rail 3. The first jaw 4 is firmly attached to the base 2 and the second jaw 5 is configured to slide on the rail 3. A tightening axle 7 traverses both jaws 4 and 5. The axle 7 is free to rotate with respect the first jaw 4 but not to slide in or out of it. The axle 7 is also configured as a screw 8 at one of its ends which is threadedly engaged with the second jaw 5. Turning the screw moves the second jaw 5 closer to, or further away from, the first jaw 4 thereby allowing the jaws to tighten around, or to release, objects.

Each vise head 1 is supported by a positioning platform 9. The platform comprises two slots 10 oriented at 90 degrees from each other, each slot 10 assigned to a vise head 1. Each vise base 2 is equipped at its bottom with an anchor 11 inserted into the corresponding slots 10. The anchor 11 allows the vise head 1 to slide along the slot 10 thereby allowing the user to position the vise heads 1 with two degrees of freedom (XY) with respect to each other. Anchors 11 are also equipped with tightening screws 12 to allow the firm attachment of the vise head 1 to the positioning platform 9. FIG. 2 provides an exploded view of the invention depicted in FIG. 1 to show clearly the slots 10 and the rails 3 allowing the vise heads to be positioned with respect to each other.

The positioning platform 9 is equipped on its underside with a mounting clamp 17 that allows it to be mounted on a work bench.

Another version of this invention is shown in FIG. 3. In this version, the vise heads 1 are provided with a larger number of degrees of freedom than in the FIG. 1 version. The anchors 11 used in attaching the vise heads 1 to the positioning platform 9 include a swivel 13 and a telescoping pole 15 that add three rotational degrees of freedom and one translational degree of freedom to each vise head 1. The swivels 13 are each equipped with tightening screws 14 to fix the vise heads 1 in the desired orientation. The telescoping poles 15 are also equipped with tightening screws 16 to adjust the vise head 1 to the desired height.

Yet another version of the invention is illustrated in FIG. 4. In this version, the mounting clamp 17 of FIG. 1 is replaced by a bolt down base plate 20.

Yet one more version of this invention is shown in FIG. 5. This version includes three vise heads 1 instead of two. The slots 10 in the supporting platform 9 are oriented at 120 degrees from each other. The supporting platform may also be attached to the clamp 17 by means of a swivel 18 and telescoping pole system 19 to provide more flexibility if needed.

Another variation of the invention is shown in FIG. 6. A vise head can be used in conjunction with a secondary clamp. The drawing shows a first secondary clamp 21 configured to hold printed circuit boards, small panels or any other similar shaped objects.

FIG. 6 also shows another secondary clamp 22 comprising of four fully threaded rods 23 of varying lengths which support secondary clamping jaws 24. This attachment is used to hold objects which would normally be considered too large or bulky for the size of the vise head, further increasing its capabilities.

While the above description contains much specificity, the reader should not construe this as limitations on the scope of the invention, but merely as examples of preferred embodiments thereof. Those skilled in the art will envision many other possible variations within its scope. Accordingly, the reader is requested to determine the scope of the invention by the appended claims and their legal equivalents, and not by the examples which have been given.
