This invention relates to vises or clamping devices used to hold a workpiece and/or a tool. The invention more particularly concerns a multi-function vise assembly adapted to perform a variety of clamping functions in a variety of applications.
Vises and similar clamping devices are of course very well known. Vises have evolved from the hard-mounted industrial vise used in a machine shop to demountable vises used in the home work shop. As the home “do-it-yourselfer” has become more prevalent, so too has the need for vises that can clamp a variety of workpieces in a variety of orientations. As a result, vises have been developed that can be clamped to the edge of a work bench, that are capable of variable two and three-dimensional angular orientations, and that incorporate clamping components.
There remains a need for a truly universal vise assembly that can be configured to clamp a variety of workpieces or tools in a wide range of orientations. This vise apparatus would also be capable of mounting in a number of ways, whether edge mounted or surface mounted.
In accordance with one embodiment of the present disclosure, there is provided an assembly that comprises a vise apparatus including (i) a first clamping component, (ii) a second clamping component, and (iii) a slide bar possessing a polygonal-shaped outer surface, the slide bar being at least partially interposed between the first clamping component and the second clamping component. The assembly further includes a first mounting apparatus including (i) a first clamping device configured to engage the polygonal-shaped outer surface of the slide bar so as to releasably hold the slide bar in fixed relation to the first clamping device, and (ii) a first attachment mechanism configured to removably secure the first mounting apparatus to a first support, the first attachment mechanism possessing a first configuration. Moreover, the assembly includes a second mounting apparatus including (i) a second clamping device configured to engage the polygonal-shaped outer surface of the slide bar so as to releasably hold the slide bar in fixed relation to the second clamping device, and (ii) a second attachment mechanism configured to removably secure the second mounting apparatus to a second support, the second attachment mechanism possessing a second configuration which is different from the first configuration.
In accordance with another embodiment of the present disclosure, there is provided an assembly that comprises a vise apparatus including (i) an elongated member possessing an outer surface, (ii) a first clamping component attached to a first end portion of the elongated member, and (iii) a second clamping component defining a passage through which the elongated member extends. The assembly further includes a first mounting apparatus including (i) a first clamping device configured to engage the outer surface of the elongated member so as to releasably hold the elongated member in fixed relation to the first clamping device, and (ii) a first attachment mechanism configured to removably secure the first mounting apparatus to a first support, the first attachment mechanism possessing a first configuration. In addition, the assembly includes a second mounting apparatus including (i) a second clamping device configured to engage the outer surface of the elongated member so as to releasably hold the elongated member in fixed relation to the second clamping device, and (ii) a second attachment mechanism configured to removably secure the second mounting apparatus to a second support, the second attachment mechanism possessing a second configuration which is different from the first configuration.
Pursuant to yet another embodiment of the present disclosure, there is provided an assembly that comprises a vise apparatus including (i) a first clamping component, (ii) a second clamping component, and (iii) an elongated member possessing an outer surface, the elongated member being at least partially interposed between the first clamping component and the second clamping component. The assembly also includes a first mounting apparatus including (i) a first clamping device configured to engage the outer surface of the elongated member, (ii) a first attachment mechanism configured to removably secure the first mounting apparatus to a first support, and (iii) a ball and socket clamping assembly interposed between the first clamping device and the first attachment mechanism and configured to releasably secure the first clamping device at any one of a plurality of orientations in relation to the first attachment mechanism. Additionally, the assembly includes a second mounting apparatus including (i) a second clamping device configured to engage the outer surface of the elongated member, (ii) a second attachment mechanism configured to removably secure the second mounting apparatus to a second support, and (iii) a frame structure interposed between the second clamping device and the second attachment mechanism and configured to secure the second clamping device at a predetermined orientation in relation to the second attachment mechanism.
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and described in the following written specification. It is understood that no limitation to the scope of the invention is thereby intended. It is further understood that the present invention includes any alterations and modifications to the illustrated embodiments and includes further applications of the principles of the invention as would normally occur to one skilled in the art to which this invention pertains.
An assembly 10, shown in
As shown in
Details of the first mounting apparatus 12 will be explained with reference to
The base 20 further defines a channel section 29 that is configured to receive the clamp assembly 30 of the first mounting apparatus 12. The clamp assembly 30 includes a body 32 that is configured to fit within the channel section 29. Attachment elements 33 are provided to attach the clamp body 32 to the base 20. In the illustrated embodiment, the attachment elements 33 include a backing plate and screws that fit within a recess formed in the clamp body, wherein the screws engage mating bores defined in the base 20. The attachment elements may also help retain the lower edge of the pressure plate 24.
The clamp assembly 30 includes a movable pressure plate 35 that is arranged to engage the underside of the work bench B in a known manner. The movable pressure plate may be provided with an appropriate gripping or friction-enhancing surface. The pressure plate 35 includes a stem 36 that is engaged within a mating bore 38 in an adjustment screw 37. The adjustment screw 37 includes external threads that are engaged within a threaded bore 41 defined in an upstanding flange 40 connected to the clamp body 32. It can be appreciated that the adjustment screw 37 may be manually rotated to advance the screw, and consequently the pressure plate 35, toward the work bench to sandwich the work bench between the two pressure plates 24 and 35. The features of the first mounting apparatus 12 as just described allow it to be fastened to the edge of a work bench, as shown in
The first mounting apparatus 12 further comprises a ball and socket arrangement. In particular, the socket body 22 defines a lower socket portion 44. This portion 44 may include a truncated spherical surface, or may incorporate stepped surfaces. The socket body 22 further defines external threads 45 about the lower socket portion 44. The upper portion of the socket is formed by a socket insert 47. The insert 47 includes an engagement rim 48 that is configured to contact a corresponding rim 52 defined on the interior of a clamping nut 50. The clamping nut includes internal threads 51 for engaging the threads 45 of the lower socket portion 44.
The first mounting apparatus 12 further includes a ball element that is formed by combining two ball halves 55 and 56. Each ball half includes an integral stem 57, 58. Recessed attachment elements 59 (only one element 59 is shown in
The opposite stem half 58 defines an opposing head half 65 that has a cavity 66. A brake insert 68 fits within the cavity 66, with its surface 69 opposing the brake surface 63 of the other head half 62. In accordance with one aspect of the clamping device 60, one brake surface, such as surface 63 is relatively fixed, while the other surface, namely brake surface 69 of insert 68, is movable toward the fixed surface. Preferably, the movable brake surface 69 is configured to mate with the exterior surface 93 of the slide bar 14c. It can be appreciated that the brake insert 68 may be removed and replaced to accommodate different sizes or configurations of slide bars 14c. The movable brake insert 68 is adjusted by way of a clamping screw 71 that is threaded through a bore defined in the head half 65 (not shown), with the tip of the screw 71 bearing against the brake insert 68.
In one embodiment, the head half 65 includes guide fingers 72 extending toward the other head half 62. The head half 62 defines guide ribs 73 that interleave with the guide fingers 72 when the two halves are fastened together. This arrangement provides superior resistance to opening up of the head halves when the slide bar 14c is clamped therebetween.
When the first mounting device 12 is assembled, the ball halves 55, 56 are joined using the attachment elements 59, with the movable brake insert 68 disposed between the head halves 62, 65. The adjustment screw 71 may be initially backed off so that adequate space is provided between the brake surface 63 and the brake insert 68 to allow the slide bar 14c to be inserted therebetween. The assembled ball component is placed within the lower socket portion 44 with the assembled stem halves 57, 58 extending upward. The socket insert 47 is placed over the assembled ball component and the clamping nut 50 is engaged to the threads 45 of the lower socket portion 44. At least initially, the clamping nut is only loosely tightened a sufficient amount to maintain the ball and socket assembly together. Once the angular orientation of the clamping device 60 has been established, the nut 50 may be fully tightened to clamp the ball component between the socket insert 47 and the lower socket portion 44.
The socket insert 47 may be provided with notches 49 that are sized to receive the combined stem 57, 58 thereby increasing the range of rotation of the combined ball element 55, 56 in relation to the socket body 22. It can thus be appreciated that the first mounting apparatus 12 is extremely flexible and versatile in its use, allowing the craftsman to support a workpiece or tool in a wide range of positions relative to the work bench to which the base is fastened.
An alternative configuration for the upper pressure plate of the first mounting apparatus 12 is shown in
Details of the vise apparatus 14 can be understood with reference to
In one embodiment, the body 75 defines a dovetail receptacle 82, preferably on the top of the body. The receptacle is configured to mate with a complementary dovetail mount 85a formed on a body 86 of an attachment 84. In one specific embodiment, the attachment 84 includes a bendable shaft 84a that can be bent to orient a light source 85 above the workpiece W, as shown in
Returning to
An alternative second clamping component 14b′ and alternative elongated slide bar 14c′ is shown in
The first clamping component 14a includes a base 102, as shown in
The locking plate is confined between the bottom cover 114 and the interior structure of the base 102. The bottom cover includes feet 115 that are adapted to be supported on a work surface. Attachment elements 116 fasten the cover to the base to contain the locking plate 108 within the hollow base. A support plate 118 extends from the bottom cover and is configured to support a biasing element 112 that bears against the locking plate 108. In one embodiment, the biasing element is a compression spring.
The locking plate 108 is free to pivot within the hollow base 102 against the spring bias of the biasing element 112 from the angled position shown in
Note that when no force is being applied to the release button 125, the first clamping component 14a may still be slid over the bar 14c to bring the first clamping component 14a toward the second clamping component 14b. However, the opposite is not true. Indeed, when no force is being applied to the release button 125, the locking mechanism prevents the first clamping component 14a from being slid over the bar 14c to advance the first clamping component 14a away from the second clamping component 14b. The reason for this operation is as follows. When slide bar 14c is being inserted through the opening 104 defined in the base 102, the slide bar pushes against the locking plate 108 so as to compress the biasing element 112 and move the locking plate into a more vertical orientation. Movement to a more vertical orientation increases the vertical profile of the locking opening 109 to a point in which the slide bar 14c is able to be continuously advanced therethrough. In contrast, when the slide bar 14c is attempted to be advanced out of the opening 104 in the direction opposite to that described above, the slide bar urges the locking plate 108 toward a more angled, locked position thereby causing the edge structure of the locking plate 108 that defines the locking opening 109 to dig into the slide bar 14c.
The craftsman may easily adjust the location of the first clamping component 14a relative to the second clamping component 14b along the bar 14c by depressing the release button 125 while sliding the base 102 along the bar. Once the base is at the desired distance from the second clamping component 14b, manual pressure on the button may be removed and the biasing element 112 will force the locking plate 108 into its angled locking position. As the locking plate pivots to the locking position, the top end 122 of the plate will return the release button 125 to its initial position for easy access.
It is contemplated in certain embodiments that the final clamping position of the clamping components 14a, 14b may be established only by manipulation of the locking plate 108. However, in a preferred embodiment, the locking plate is used to achieve a rough initial positioning of the first clamping component 14a. The final clamping may be effected by a movable backing plate 130, as shown in
An adjustment screw 136 is provided that is operable to move the backing plate 130 relative to the base 102. The adjustment screw includes a handle 137 that is configured to be manually rotated by the craftsman. External threads 138 on the adjustment screw 136 mate with threads in the adjustment screw bore 140 in the base 102. Thus, rotation of the adjustment screw causes the adjustment screw stem 142 to move toward or away from the base 102.
The backing plate 130 is connected to the stem 142 so that the plate moves with the stem along the bar 14c. In one embodiment, the stem 142 extends into a stem bore 144 defined in the mounting head 132 (
In the embodiment of
The vise apparatus 14 may be supported on a work bench B, as shown in
It is also contemplated that the vise apparatus 14 may be supported on a work station, such as the work station 162 depicted in
In the illustrated embodiment, the clamping elements include a bar holder 182 with a clamping surface 183 that is configured to mate with the external surface 93 of the bar 14c. A movable support body 186 carries a clamp insert 185 that also includes a contoured clamping surface. Thus, the bar 14c is clamped between the clamp insert 185 and the bar holder 182. An adjustment screw 188 passes through one of the end plates 178 and advances or retracts the movable support body 186 as the screw is rotated. Like the clamping device 60, the two brake elements are interlocked when fingers 190 and ribs 191 are interleaved.
As shown in
In addition to supporting the vise apparatus 14, the first mounting apparatus 12 may be used alone to support a tool, as shown in
It is understood that the dimensions of the components of the assembly 10 may be adjusted depending upon the size of workpieces to be clamped and the type and dimensions of the work surfaces on which the system is supported. For instance, the first mounting apparatus 12 may be sized to be clamped onto a work table having a thickness ranging from ¾ to 2½ inches. The vise apparatus 14 may be configured to have a maximum jaw opening of 7¼ inches. The post 150 of the tool holder 16 may have a length of 2 inches. The combined stem 57, 58 of the first mounting apparatus 12 may be sized to elevate the clamping device 60 1-1½ inches above the swivel insert 47.
As described above, the first mounting apparatus 12 includes an attachment mechanism configured to removably secure the first mounting apparatus 12 to a support (i.e. the workbench B shown in
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same should be considered as illustrative and not restrictive in character. It is understood that only the preferred embodiments have been presented and that all changes, modifications and further applications that come within the spirit of the invention are desired to be protected.
