According to another aspect of the disclosure, there is provided an apparatus having a high degree of versatility, adjustability, and/or adaptability to other non-ski, snowboard, bicycle and firearm uses.
According to another aspect of the disclosure, there is provided a portable holder for use in spaced relation with a similar holder as a ski, snowboard, bicycle and firearm support for maintenance operations at a work station, each said holder being adapted to support one of the opposing end portions of the ski, snowboard, bicycle or firearm. The portable holder comprises a base section adapted to be fixed to the work station in a generally upright position and a rod portion mounted to the base section in a generally upright and vertical orientation. A support head mounted upon the rod allows a variety of modular supports, platforms and brackets to be removably mounted to the support head including ski and snowboard supports, bicycle fork mounting brackets, bicycle bottom bracket shell supports and gun cradles. The rod may be threaded.
According to another aspect of the disclosure, there is provided a portable holder for use in spaced relation with a similar holder as a ski and snowboard support, each said holder being adapted to support one of the opposing end portions of the ski or snowboard. The portable holder comprises a base section adapted to be fixed to the work station in a generally upright position and a threaded rod portion mounted to the base section in a generally upright and vertical orientation. A support head mounted upon said threaded rod allows a ski and snowboard support to be mounted to the holder. The ski and snowboard support typically has a resilient top surface to frictionally engage the ski or snowboard when resting thereon and includes a vertical slot for holding both a ski and snowboard in a generally upright position to permit convenient side edge work. The vertical slot of the support is of a sufficient width that when either a ski or snowboard is placed upright in said slot the ski and snowboard support, support head and threaded rod portion of the holder can be rotated as a unit about the base section of the holder and the holders' vertical axis such that two opposing longitudinal edges of said slot act to clamp the ski or snowboard in a fixed upright position. A nut on the lower portion of the threaded rod turned against the top portion of the base allows the ski and snowboard support, support head and threaded rod portion of the holder to be fastened to the base section in the desired orientation preventing unwanted movement of the ski or snowboard when performing side edge tuning procedures. The ski and snowboard support, support head and threaded rod portion of the holder can also be rotated about the holders vertical axis to adjust the height of the support relative to the holder base section, or to change the orientation of the support from a position where said support is aligned across the width of a snowboard to a position where the support is aligned with the longitudinal axis of a ski. The ski and snowboard support is preferably mounted to the support head of the holder for movement between a position where the support is generally horizontal to one where the support is generally vertical, allowing the support to pivot between horizontal and vertical positions to adjust to various degrees of ski camber when the support is aligned under the longitudinal axis of a ski. A locking system is provided for locking the ski and snowboard support to the support head of the holder in either a fixed horizontal or vertical position.
According to another aspect of the disclosure, there is provided a portable holder typically positioned in spaced relation along the edge of a tabletop, work station or support such that the first holder is placed under or in close proximity to a bicycle frame bottom bracket shell and the second holder is positioned under either the front bicycle dropout or rear bicycle dropout. In this manner the proximity of the holders in relation to each other can be easily and independently adjusted according to bicycle frame size. The first holder comprising a bottom bracket shell support is typically positioned in close proximity to one corner of the tabletop, work station or support so as to allow either the front or rear bicycle wheel sufficient clearance off the table or stand to spin freely, and said holder is of a sufficient height so as to allow the bicycle crank arms and pedals sufficient clearance above the tabletop, work station or support to rotate without impediment. The bottom bracket shell support preferably has a “V” shaped profile allowing a wide variety of bottom bracket shell diameters and shapes to be cradled by said support and typically has a resilient top surface to frictionally engage the bicycle bottom bracket shell when resting thereon. The bottom bracket shell support is preferably mounted to the support head of the holder for movement between a position where said support is generally horizontal to one where said support is generally vertical, allowing said support to pivot between horizontal and vertical positions to accommodate various frame shapes in the vicinity of the bottom bracket shell, and a locking system is provided for locking the bottom bracket shell support in either said horizontal or vertical position. The first holder preferably comprises a retaining strap associated therewith to hold a bicycle frame bottom bracket shell against bottom bracket shell support, said strap being looped around and tensioned against the portion of the bicycle frame where the down tube and seat tube meet the bottom bracket shell. Mounts are provided to readily detachably mount various bicycle axles transversely through the support head of the second holder to permit fastening of a wide variety of front and rear bicycle fork ends to the holder.
According to another aspect of the disclosure, there is provided a vise assembly for use with the portable holder adapted to be mounted upon the threaded rod portion of the holder or fixed directly to a work station and used in spaced relation with similar holder(s), or in combination with the variety of modular supports, platforms and brackets described above. A vise base including a perpendicular threaded aperture allows the threaded rod of the holder to be turned into the threaded aperture of the vise base permitting mounting of the vise assembly to the threaded rod portion of the holder. A vise screw extending horizontally through the vise base with two reversely threaded sections drives oppositely disposed vise jaws toward and away from each other along at least one guide bar with the vise jaws sliding exactly parallel to each other when the vise screw is turned. The vise screw is turned by a handle assembly fastened to one end of the vise screw including a lever transversely and slidably mounted through an aperture in a handle end cap. Index finger rings mounted on each end of the lever act to prevent the lever from becoming detached from the handle assembly and allow for quick and efficient manual rotation of the handle assembly and vise screw when an index finger is placed through, or partially through, one of the index finger rings. The handle end cap is of a larger diameter than the vise screw and acts as a stop preventing the vise jaws from winding off the vise screw when vise jaws are actuated away from each other. Both vise screw and guide rod(s) are preferably detachably secured to the vise base in order to be readily exchanged with a longer or shorter vise screw and guide bar(s) depending on the width of ski, snowboard, bicycle, firearm or other sports equipment to be held in the vise assembly. Each oppositely disposed vise jaw forms a “C” shaped profile allowing a holder support head, clamp knob or a ski binding to be positioned within the vise assembly between the vise jaws when clamping. Each of the vise jaws preferably includes a recessed stepped indent to receive and hold pins of varying diameters and lengths when two oppositely disposed vise jaws are closed upon both ends of a pin extending between and perpendicular to the vise jaws. Diameters of pins are held onto which certain types of cross country, touring and backcountry touring ski bindings are fastened with said pins also able to provide anchor for an eyebolt used to fasten and support a snowboard resting base up on the holder when said eyebolt is turned into one of the snowboard threaded inserts. A flat surface exists on the top of each vise jaw allowing the vise assembly to act as a rest in addition to having clamping ability. The vise jaws are actuated towards each other to clamp either a ski or snowboard in a vertical orientation, or actuated a sufficient distance away from each other to provide stable support for a ski or snowboard resting horizontally on the flat top surface of the vise jaws. The vise assembly is able to be rotated such that the vise jaws can be positioned in line with the longitudinal axis of the ski so as not to interfere with base rilling, structuring and/or imprinting tools with vertically disposed flanges of a thickness greater than the thickness of a ski or snowboard when drawn down the ski or snowboard base as required when the ski or snowboard is resting base up. The vise jaws are typically provided with resilient jaw pads, each jaw pad covering the entire top portion of each vise jaw and shaped such that each pad is mechanically held in place against the vise jaw when clamping so as not to become detached from the vise jaw. The jaw pads are preferably made of a resilient material such as rubber so as not to dent, mar or otherwise damage the sports equipment including for instance the ski, snowboard, bicycle or firearm being clamped.
According to another aspect of the disclosure, there is provided a portable holder typically positioned in spaced relation along the edge of a tabletop, work station or support such that a first holder is placed under or in close proximity to the shovel portion of a ski or snowboard, a second holder is positioned under the binding area and a third holder is positioned under or in close proximity to the tail portion of a ski or snowboard providing an improved three point ski and snowboard support arrangement. Each of the three holders is provided with vise assemblies as described above. The first and third holders positioned under or in close proximity to both shovel and tail portions of the ski or snowboard are each equipped with support heads mounted upon the threaded rod portions of each holder. A vertical slot in each support head serves to stabilize a snowboard in a generally upright position when the support head is rotated about its vertical axis such that the vertical slot is aligned parallel with the vise jaws and the snowboard is dropped down into the slot and clamped between the vise jaws to permit convenient side edge tuning. The support head of each holder also acts as a rest for a ski placed upright on the support head then clamped between the vise jaws when the support head is rotated about its vertical axis such that the vertical slot is perpendicular to the vise jaws, thereby allowing the vise jaws to clamp the ski relatively close to its bottom edge allowing work to be done on the top edge of the ski without obstruction from the vise jaws. A ski is held either base up for base tuning or base down to facilitate binding mounting by clamping the sides of the ski in the binding area using the second holder and resting the shovel and tail portions of the ski on the top portion of the vise jaws of the first and third holders. When holding skis having an alpine binding the second holder is positioned directly under the binding ski brake. The opposing “C” shape of each vise jaw provides an open area under each jaw pad allowing the ski brake to be first retracted then held in a retracted position by the vise jaws when either the sides of a ski or ski binding are clamped by the vise jaws. In this respect the vise jaws of the second holder serve the dual purpose of clamping the ski or ski binding and retracting the ski brake. When holding skis having a binding of the Nordic variety, that is to say a binding that closes on a pin in order to fasten a ski boot to a ski, an additional mounting option exists where the vise jaws of the second holder include stepped indents to receive and hold pins of varying diameters and lengths when the two oppositely disposed vise jaws are closed on both ends of a pin placed in a perpendicular orientation between the vise jaws. At least three diameters of pins may be held in progressively smaller diameter stepped indents in each vise jaw onto which both New Nordic Norm (NNN) and Salomon Nordic System (SNS) cross country, and other touring and backcountry touring ski bindings may be fastened. To hold a snowboard base up the vise jaws of the first and third holders are actuated far enough away from each other so the top surface of the four vise jaws act as a stable four-point rest upon which the snowboard can be placed. An eyebolt turned into one of the snowboard threaded inserts can be anchored to the second holder by placing one of the pins mentioned above through said eyebolt and closing the oppositely disposed vise jaws on both ends of said pin. The threaded rod of the second holder is provided with two reversely disposed sections of threads to permit convenient height adjustment of the vise assembly relative to the base section of the holder when the vise assembly is held in position and the threaded rod is turned either clockwise or counter-clockwise, allowing the height of the vise assembly to be readily adjusted relative to the snowboard without the need to rotate either vise assembly or eyebolt. A nut or knob on the lower portion of the threaded rod turned against the top portion of the base allows the threaded rod portion of the holder to be fastened to the base in a fixed position once the holder has been adjusted to the desired height.
According to another aspect of the disclosure, there is provided a vise assembly that is mounted to the threaded rod portion of both a first holder and a second holder, each holder positioned in spaced relation along the edge of a tabletop or support such that the first holder is placed under or in close proximity to a bicycle frame bottom bracket shell and the second holder is positioned under either the front bicycle dropout or rear bicycle dropout. The vise assembly of each holder is orientated such that the vise jaws are transversely positioned relative to the length of the tabletop or support on which the supports are fastened. The vise jaws of the first holder can then be adjusted to allow the bicycle bottom bracket shell to be seated upon the top portion of both jaws in a stable manner. The first holder preferably comprises a retaining strap associated therewith to hold a bicycle frame bottom bracket shell against the top portion of the vise jaws, said strap being looped around and tensioned against the portion of the bicycle frame where the down tube and seat tube meet the bottom bracket shell. A horizontal “V” shaped groove exists in the clamping surface of each vise jaw allowing for convenient horizontal clamping of a wide variety of bicycle axles with circular cross sections in the vise jaws of the second holder, thereby allowing the front or rear bicycle dropout to be securely fastened to the second holder.
According to another aspect of the disclosure, there is provided a vise assembly in which the opposing vise jaws include apertures where resilient rubber frame pads are inserted to facilitate clamping a very wide variety of bicycle frames between the opposing vise jaws of the vise assembly. Each frame pad preferably has a “V” shaped profile allowing a very wide variety of bicycle frame tube diameters and shapes to be cradled between and held within the angled flanges of the frame pads. The frame pads are preferably made of a resilient rubber material to prevent damage to the bicycle frame and provide for good frictional engagement therewith. The vise assembly is mounted transversely on the vertically orientated threaded rod of the holder with the threaded rod turned into a corresponding threaded aperture in vise base. In this manner the vise assembly is positioned in a generally horizontal orientation with the longitudinal axis of opposing vise jaws parallel with the tabletop or support allowing vise jaws of the vise assembly to both clamp the top tube of the bicycle frame and act to suspend the bicycle a sufficient distance off the tabletop and above the ground to facilitate bicycle maintenance, adjustment or repair. Alternatively, the vise assembly can be mounted transversely on the vertically orientated threaded rod of the holder through a second threaded aperture in the vise base, positioning the vise assembly in a generally horizontal orientation, but with the vise jaws perpendicular to the tabletop. In this orientation the opposing vise jaws are able to clamp the vertically orientated seat tube of the bicycle frame, thereby holding the bicycle sufficiently off the table and above the ground to facilitate bicycle maintenance, adjustment and repair operations thereon.
According to another aspect of the disclosure, there is provided a first holder is for use in spaced relation with a second similar holder as a firearm support, each said holder being adapted to support one of the opposing end portions of a firearm. The holder comprises a base section adapted to be fixed to the work station in a generally upright position and a threaded rod portion mounted to the base section in a generally upright and vertical orientation. A support head mounted upon said threaded rod allows a gun barrel cradle to be mounted to first said holder. The gun barrel cradle typically has a resilient top surface to frictionally engage a gun barrel, said cradle preferably having a “V” shaped profile permitting a wide variety of barrels to be automatically centered relative to the vertical axis of said cradle when resting thereon. The gun barrel cradle is preferably mounted to the support head of the holder for movement between a position where said cradle is generally horizontal to one where said cradle is generally vertical, allowing said cradle to pivot between horizontal and vertical positions to accommodate various barrel inclination angles, and means are provided for locking said cradle in either a fixed horizontal or vertical position. A vise assembly as described above is mounted to the threaded rod portion of the second holder with the vise base typically having a resilient top surface to frictionally engage the bottom of a gunstock resting thereon permitting centered clamping of the gunstock along its longitudinal axis between oppositely disposed vise jaws. The threaded rod of the second holder is provided with two reversely disposed sections of threads to permit convenient height adjustment of the vise assembly and gunstock relative to the base section of the holder when the vise assembly is held in position and the threaded rod is turned either clockwise or counter-clockwise, allowing the height of the vise assembly and angle of inclination of the firearm to be readily adjusted relative to the holders. A nut or knob on the lower portion of the threaded rod turned against the top portion of the base allows the threaded rod portion of the holder to be fastened to the base in a fixed position once the holder has been adjusted to the desired height.

One embodiment has specific features for holding a frame, such as a frame for a bicycle.
An embodiment may also be used to hold other devices, objects, items and articles, such as building materials, construction tools, etc.
For an embodiment, the clamp and tensioning device provides support for maintenance operations of the held device at a work station (which may include any suitable work area, such as a work stand, workbench, tabletop, desk, etc.). In one embodiment, the clamp and tensioning device is portable and comprises a clamp frame; a threaded clamping screw and clamping plate mounted to the clamp frame and two jamming cleats integrally formed as part of the clamp frame, where the frame is adapted to be fixed to the work station in a generally upright position and a clamping screw portion attached to the frame in a generally upright and generally vertical orientation.
In one aspect, an embodiment provides that the cleat integrally formed as part of the clamp frame allows a length of rope, elastic or accessory cord to be readily detachable from the C-clamp frame, which is necessary when it is not convenient or practical to loop a rope, elastic or accessory cord entirely around a large object, for example when an elastic cord is looped through a bicycle frame and tensioned against the portion of the bicycle frame where the down tube and seat tube of the bicycle frame meet the bottom bracket shell. An aspect provides that a rope, elastic or accessory cord is anchored without the use of rivets or other fasteners simply by tying a knot in one end of the rope or cord, threading the rope or cord through an aperture in the clamping plate, then compressing the clamping plate against a stationary support to capture the knot within the clamping plate.
In another aspect, an embodiment provides that the cleat is integrally formed as a part of the clamp frame and positioned to be easily accessed from both sides of the clamp frame in order to fix a rope or cord in the cleat, not mounted vertically on one side of the C-clamp frame where it is not possible to fix the cord from the opposite side of the clamp frame.
According to another aspect of the disclosure a clamping plate is able to secure a length of cord, where the cord is knotted and threaded through an aperture in the clamping plate, so as to provide a simple and convenient anchor point from which to pull and tension the cord around or through a workpiece and then fix the cord in a jamming cleat integrally formed as part of a clamp frame for the purpose of binding the workpiece to the clamp. According to another aspect of the disclosure a support head mounted upon the clamping screw allows a variety of modular supports, platforms and brackets to be removably mounted to the support head including, for example, ski and snowboard supports, gun cradles, bicycle fork mounting brackets and bicycle bottom bracket mounting supports. In another embodiment additional clamp frames may be interlocked and fastened directly to the clamp and tensioning device employing interlocking feature integrally formed as part of the clamp frame. In yet another embodiment of the disclosure a second clamp frame may be mounted upon the clamp screw portion of the clamp and tensioning device providing a height-adjustable clamping apparatus.

For the purpose of convenience, and not limitation, where the term “cleat” or “first protrusion” is used herein, it will be understood that any protrusion or feature described herein may be provided in place of the described cleat or first protrusion unless otherwise noted. An exemplary cleat or first protrusion may be comprised of one or more walls and/or components as noted above.
At the top of cleat 3400, from one or both sides of cleat 3400, a second feature extends towards the center line of the spine of frame 3000 to impede removal of cord 5000 through the top of cleat 3400. In one embodiment the feature(s) are multiple teeth 3700 that extend towards the center line and are dimensioned to be able to catch and secure cord 5000 when located in slot 3600. As shown, there is one set of teeth 3700 on one side of frame 3000 and a second set of teeth 3700 on the opposite side of frame 3000. The two sets of teeth 3700 have a gap therebetween, which may be dimensioned (along at least a part of it) to allow cord 5000 to pass through, with at least some resistance. However, an alternative gap (or at least a part of it) may be dimensioned to not allow cord 5000 to pass through. The two sets of teeth 3700 are shown as being symmetric in size and shape. However, asymmetric sizes may be provided, where one set of teeth 3700 is larger than the other set. For example, one set of teeth 3700 may extend past the center line of cavity 3300. A recessed groove 3800 in the mid-portion of clamp frame 3000 between the L-shaped cavities 3300 guides cord 5000 when tensioned providing a mechanism to quickly and easily properly position cord 5000 so the multiple teeth 3700 of the V-shaped slot 3600 of cleat 3400 are able to catch and hold the cord 5000 securely. In other embodiments, one of the two cavities 3300 can be provided or a continuous cavity can be provided where upper and lower cavities 3300 are joined to form the continuous cavity. In embodiments, the teeth may be formed from a (second) protrusion, nodule, bump or any protruding feature extending towards the center line of frame 3000. For the purpose of convenience, and not limitation, where the term “teeth”, “tooth” or “second protrusion” is used herein, it will be understood that feature(s) described in this paragraph may be provided in place of the described “teeth”, “tooth” or “second protrusion” unless otherwise noted. The teeth or second protrusion may be comprised of one or more teeth and/or components as noted above. Further the teeth or second protrusion may be further provided in sets. In one example, two (or more) sets are provided for the second protrusion, where a first set of features (e.g. teeth) is located on one side of cavity 3300 and a second set of features (e.g. opposing teeth) is located on the other side of cavity 3300. Additional set(s) of teeth may be located within cavity 3300.
In addition to catching and holding cord 5000, in one embodiment the shape of slot 3600 and diagonal alignment of teeth 3700 relative to the horizontal orientation of lower jaw 3100 and upper jaw 3200 of frame 3000 structurally reinforce and strengthen each corner 3500 of clamp frame 3000. It will be appreciated that in other embodiments, other shapes, sizes, orientations and features can be provided for cleat 3400, groove 3800 and teeth 3700. For example in one embodiment, no tapering of the sides (as provided by slot 3600) may be provided or only one side may be tapered. The tapering may or may not be symmetrical, when both sides are tapered. Other features may be provided to provide interference of removal of cord 5000 from cavity 3300, such as one or more protrusions along one or both of the walls in cavity 3300. The protrusions may be offset from each other or they may align with each other. In another embodiment, one or more of the features may protrude from the outside surface of frame 3000. In one embodiment cleat 3400 is integrated into frame 3000. In other embodiments, cleat 3400 may be a separate feature that is snapped into, fastened, welded, and/or held via a friction fit in cavity 3300.

Details on a second aspect of an embodiment are provided. For this aspect, clamp 2000 is matable with one or more clamps 2000 via a set of mating features provided on clamps 2000 that are being fit together. The mating features may interact with each other to provide a positive locking attachment between the two clamps 2000.
It will be appreciated that for an embodiment, the second aspect may be provided that facilitates mating of two components together through a variety of first and second physically and dimensionally complementary features of the two components. For example, mating features can be provided on the first and second clamps 2000 and other components, such as plate 4300 to allow clamps, plates and other components to be connected together.
The mating feature has a first feature on one component and a second feature on another component. Using first clamp 2000 as an example, the first feature may be any protrusion extending from a surface of clamp 2000 and may be a male feature (as described below), nodule, bulge, extension, bump, wall, post, rail, hook, bar or any other feature that may protrude outwardly from frame 3000. Using a second clamp 2000 as an example, the second feature may be any complementary feature extending in the surface of the second clamp 2000 and may be a female feature (as described below), depression, rail, hook, groove, slot, channel or any other feature that may extend inwardly to frame 3000 to receive the first feature in whole or in part. For the purpose of convenience, and not limitation, for the mating features, where the term “male feature”, “first mating feature” or “third protrusion” is used herein, it will be understood that these terms capture any protrusion described for the male feature herein and may be provided in place of the described male feature unless otherwise noted. Also, where the term “female feature” or “second mating feature” is used herein, it will be understood that these terms capture any depression described for the female feature herein and may be provided in place of the described female feature unless otherwise noted.
For one embodiment for the second aspect,
As shown, first and second clamps 2000 have identical placements of male and female features 1010 and 1020. Using first clamp 2000 to describe the locations of the features, in the middle of the middle portion of frame 3000 a male feature 1010 is a hub that extends outwardly from the inner surface of the middle portion and on the direct opposite side on the middle portion, a female feature 1020 is a depression that extends inwardly into frame 3000. At about the distal ends of each of upper and lower jaws 3100 and 3200, male feature 1010 extends outwardly from the outer surface of the jaw away from the other jaw and on the direct opposite side on the jaw, a female feature 1020 is provided on the interior surface that extends inwardly into frame 3000 towards the other jaw. In other embodiments, the male and female feature locations may be reversed. For one embodiment, providing male/female features 1010 and 1020 in complementary locations and having the features symmetrically located along frame 3000, allows any two or more clamps to be mated together like a series of bricks, forming a ‘wall’. For example, when a first clamp 2000 is mated to a second identical clamp 2000, having an arrangement of male/female features as shown in
In other embodiments additional or less features may be provided than those shown in
In one embodiment male feature 1010 on frame 3000 of the first clamp has physical features to facilitate orienting of the first clamp to the second clamp. In one embodiment, the physical feature is a set of teeth. One specific embodiment provides sixteen (16) evenly spaced teeth 1090 along the outer side of male feature 1010. Correspondingly, the female feature 1020 has sixteen (16) complementary evenly spaced teeth 1090 along its inner side. These inner and outer teeth are not the same as the teeth described for the second protrusion, noted earlier.
The outer and inner teeth facilitate clamps 2000 to be oriented in different set angles to each other, when male feature 1010 is inserted into female feature 1020, but in a locked orientation to each other. Having 16 spaced teeth provides 22.5 degree increments (360 degrees/16 teeth) for positioning clamps 2000 about each other.
Other numbers of teeth may be provided for the male and female features 1010 and 1020, for example, any number of teeth between two (2) and sixty (60) on the two features 1010 and 1020. It will be appreciated that other physical features instead of teeth may be employed to interlock two frames 3000 in at least two or more positions relative to each other. Different exemplary shapes for male feature 1010 and female feature 1020 include shapes having a perimeter of any of a triangle, square, pentagonal, hexagonal, star, etc. Two or more frames 3000 may be joined to each other at a variety of angles by mating male feature 1010 and female feature 1020. Male feature 1010 and corresponding female feature 1020 joining each frame may be reversed or interchanged. For the purpose of convenience, and not limitation, where the term “orientating feature” is used herein, it will be understood that any protrusion described herein may be provided in place of the described teeth in this paragraph and the preceding paragraph and the shapes described in this paragraph unless otherwise noted. As noted earlier clamping plate 4300 may have either the male or female feature 1010 or 1020 provided thereon to allow plate 4300 to mate with a complementary mating feature on clamp 2000, per
Each feature 1010 and 1020 may have aperture 1050 that may receive a locking mechanism, such as thumb screw 1070 to engage and lock the meshed male and female features together when thumb screw 1070 is turned into corresponding threads in aperture 1050. Aperture 1050 may or may not be threaded to engage with any threads on screw 1070. As shown in
Now, further details are provided on other aspects of an embodiment.

It will be appreciated that in other embodiments, two components may be mated together with various clamping, threading and/or other locking or engagement systems known to those of skill in the art. An embodiment has described threaded rods and apertures for connecting and orienting the base section to the support head. In other embodiments, the threaded portion in the aperture in the base may be provided on the support head. In other embodiments, a clamp or friction fit system may be used instead of or in addition to the threads on the rod and the support head. For example, a telescoping rod may be provided with a swivel joint attached to its head. A locking pin may be provided to lock the rod in place. The pin may engage with apertures on the rod. Alternatively or additionally a collar may be provided that can be tightened in place around or about the rod to lock the rod at a given orientation and/or displacement. Such systems may also be provided in the vise jaws, as described earlier.
It will be appreciated that features describing aspects of embodiments as being “straight”, “horizontally oriented”, “vertically oriented”, “upright” or in other terms relating to position or orientation have a range of acceptable values or positions that, if provided, still provide a functional embodiment. For example, a component described as being “horizontal” will encompass an embodiment where the component is substantially horizontal. As a further example, if two components are described as being “parallel” in orientation, other embodiments will tolerate the two components being aligned in a nearly parallel fashion. Similarly, if a component is described as being “straight”, other embodiments will tolerate a component being nearly straight. It will be plainly obvious to a person of skill in the art as to what range of values would be acceptable. Further, elements that are described as being “integrated” with another element may be provided as distinct, separate elements that are joined together, in another embodiment and vice versa.
Although the disclosure has been described with reference to certain specific embodiments, various modifications thereof will be apparent to those skilled in the art without departing from the scope of the disclosure as outlined in the claims appended hereto.
