A set of jaws 200, including an actuatable first jaw 200A and a second jaw 200B, coupled to the base 100, wherein the first jaw 200A comprises a first actuator 210A, and provides a first contact surface 220A and the second jaw 200B provides a second contact surface 220B, wherein the first contact surface 220A and the second contact surface 220B are mutually opposed and transverse to the area. The actuatable first jaw 200A is wedge shaped and slides orthogonally relative to the length of the base. The wedge angle is between 5 and 50 degrees. The height of the first contact surface 220A compared to the height of the base 100 is between the range of 2:1 and 100:1. Unilateral actuation of the of the first actuator 210A causes the vice to move from the open position to the closed position. The second jaw 200B can also have a second actuator where a third position can be obtained by movement of the second actuator.

Description

Field

The present invention relates to vices for securing workpieces.

Background to the invention

Typically, installation (also known as hanging) of a door in a door frame is multistep and complex, typically requiring two or more installers. Generally, door frames are for external doors while door linings (also known as casings or casements) are for internal doors. Herein, the term door frame is used with reference to both external and internal doors. Firstly, the door and/or the door frame are cut to size, hinges fitted to the door and corresponding hinge recesses for the hinges cut in the door frame. Secondly, the door is offered up to the door frame at a slight angle and a top hinge attached to the frame, by screwing therein a single screw. To facilitate this step, a door lifter may be used. Generally, the door lifter is a foot-operated lever that has a nose that slides under the door. By pushing downwards with a foot on an opposed end of the door lifter, the nose pivots about a pivot, lifting the door upwards. Generally, during this step, only the single screw is screwed into the door frame, in case adjustment, such as resizing of the door, the door frame, the hinge recesses and/or repositioning of the single screw is required. Such adjustment typically requires the door to be removed from the frame for the adjustment and the second step to be repeated. Further adjustment may be required, necessitating repeated removal and replacement of the door. If no adjustment or further adjustment is required, the remaining hinges may be attached to the door frame and all screws may be screwed therein.

However, even using a door lifter, aligning the door in the door frame and/or maintaining the door in alignment is problematic. For example, the door lifter tends to pitch the top of the door (i.e. tilt forwards or backwards), such that the top hinge may not fit squarely in the corresponding recess in the door frame. For example, a change in foot pressure on the door lifter may move the door out of alignment. For example, since the door lifter is relatively narrow (typically 25 mm to 50 mm wide) compared with a standard internal door width of 762 mm, the door tends to roll (i.e. tilt sideways) if the door lifter is not positioned centrally with respect to the door. For example, even when aligned, the door must be held with at least one hand to maintain alignment while the foot pressure on the door lifter is constant, making single-handed screwing of the screw of the top hinge into the door frame difficult. These problems are further compounded for relatively heavier doors, such as solid external doors and/or fire doors, further increasing a safety risk. For example, FD30 fire doors weigh approximately 45kg while FD60 fire doors weigh upwards of 75kg. Further, if the installer requires to retrieve an item, such as a power tool or a screw, that is beyond reach, the door must be lowered and later realigned.

Hence, there is a need to improve installation of doors. More generally, there is a need to improve securing of workpieces.

Detailed Description of the Invention

According to the present invention there is provided a vice, as set forth in the appended claims. Other features of the invention will be apparent from the dependent claims, and the description that follows.

First aspect The first aspect provides a vice comprising: a base, wherein the base defines a polygon of support having an area A,, and has a height Hr, orthogonal to the area A,, ; a set of jaws, including an actuatable first jaw and a second jaw, coupled to the base, wherein the first jaw comprises a first actuator, wherein the first jaw provides a first contact surface and the second jaw provides a second contact surface, wherein the first contact surface and the second contact surface are mutually opposed and transverse, preferably orthogonal, to the area Ah, and wherein the first contact surface has a height hi i, transverse, preferably orthogonal, to the area Ab and a width wit 1; wherein the vice is arrangeable in: a first configuration, wherein the first contact surface and the second contact surface are spaced apart by a first length wherein the first configuration is an open configuration and wherein the first length lit is a maximum spacing between the first contact surface and the second contact surface; and a second configuration, wherein the first contact surface and the second contact surface are spaced apart by a second length /it.2, wherein the second configuration is a closed configuration; wherein the vice is arranged to move from the first configuration to the second configuration by unilateral actuation of the first actuator; and wherein a ratio Rhp bt of the height h1, of the first contact surface to the height Hi, of the base is in a range from 2: 1 to 100: 1, preferably in a range from 5: 1 to 50: 1, more preferably in a range from 10: 1 to 25: 1.

In this way, the vice is arrangeable to support a workpiece, for example a door during installation thereof in a door frame, such that the workpiece is freestanding (i.e. without manual support). It should be understood that the workpiece is generally oriented vertically, in use, in the vice, with the base oriented horizontally, for example proximal the ground. Particularly, the relatively small height Hb of the base, relative to the height hi, of the first contact surface of the first jaw (as defined by the ratio R. 10 allows the vice to be positioned under the workpiece in situ, for example under the door during installation thereof in the door frame. In other words, the vice has a low profile base that may fit under a door, for example. Typically, the gap under an installed door is in a range from about 3 mm to more than 30 mm, depending on whether and/or how the floor is finished, for example. The door is secured freestanding therein, by clamping between the first jaw and the second jaw (i.e. against the first contact surface and the second contact surface thereof, respectively), thereby maintaining alignment of the door in the door frame. Since the height hit of the first contact surface of the first jaw is relatively large, relative to the height 1-4, of the base (as defined by the ratio Rh, ht), pitching of the top of the door may be reduced. Since the base defines the polygon of support, rolling of the door may be reduced. Particularly, manual holding, such as by foot pressure or with a hand, of the door is not required, freeing up both hands and hence facilitating attaching of the hinges to the door frame. Furthermore, since the door is freestanding in the vice, the installer may retrieve an item, such as a power tool or a screw, that is beyond reach, if required, without lowering the door, for example. In this way, installation of doors is improved. In this way, safety is improved. Such advantageous securing of the door extends more generally to securing of workpieces. Base

The vice comprises the base, wherein the base defines the polygon of support having the area Ab and has the height Hb orthogonal to the area Al, . It should be understood that the height Hb of the base is measured between the first jaw and the second jaw i.e. under the In one example, the base comprises and/or is a planar base. In this way, the base may fit under the door while those parts of the base either side of the door do not present a trip hazard.

In one example, a work surface extending across the base, through the set of jaws, comprises no protrusions upstanding therefrom. In this way, the door may stand directly on the work surface and/or be moved sideways by sliding thereon, for example, thereby further facilitating alignment of the door in the door frame.

In one example, the vice is for securing a door during hanging thereof in a door frame, wherein the base is arrangeable under the door.

In one example, the vice is a free-standing vice (i.e. self-supporting, not adapted for attachment to a work bench, for example). In one example, the vice, for example the base, comprises no fixtures, fittings and/or attachment points for attaching to a work bench, for example.

Polygon of support The base defines the polygon of support having the area At, . In one example, the polygon of support provides N points of support, wherein N is a natural number greater than or equal to 3, for example 3, 4, 5, 6, 7, 8, 9,10 or more. The N points of support may be defined as ground contacting points of support. Where the base comprises and/or is a planar base, N may be defined, for convenience, as a number of sides of the base. For example, if the base comprises and/or is a triangular planar base or a square planar base, N is may be defined as 3 and 4, respectively. If the base comprises and/or is an elliptical planar base, for example a circular planar base, N may be defined as at least 3. Where the vice comprises a set of feet and/or a set of wheels, N may be defined as the number of feet or wheels, respectively. In one example, the base comprises and/or is a trapezoidal planar base or a parallelogram planar base. In one example, the base comprises and/or is a square planar base having one or more corners cut therefrom. Generally, triangular, trapezoidal, parallelogram and square bases (having one or more corners cut therefrom) are preferred when hanging doors since the base may be positioned relatively more proximal a door frame and/or an adjoining wall, for example. Jaws

The vice comprises the set of jaws, including the actuatable first jaw and the second jaw, coupled to the base.

Jaws are known, in the technical field of vices. A conventional vice comprises a sliding jaw and a fixed jaw, wherein the sliding jaw is an example of an actuatable jaw, typically comprising a threaded actuator. It should be understood that the actuatable first jaw of the vice according to the first aspect is not limited to such a sliding jaw of a conventional vice, as described below.

In one example, the first jaw comprises a first part, fixedly coupled to the base, and a second part, moveably and/or releasably coupled to the first part, wherein the second part includes the first contact surface, wherein the unilateral actuation of the first actuator urges the second part to move relative to the first part. In this way, the vice is arranged to move from the first configuration to the second configuration according to this relative movement of the two parts of the first jaw and a force exerted on the workpiece, for example a door, is transferred to the base, to which the first part is fixedly coupled. In one example, the first actuator is arranged between the first part and the second part of the first jaw.

In one example, the second jaw is a non-actuatable jaw or a fixed jaw, for example fixedly coupled to the base.

In one example, the second jaw comprises and/or is an actuatable jaw comprising a second actuator and wherein the vice is arrangeable in: a third configuration, wherein the first jaw and the second jaw are spaced apart by a third spacing; wherein the vice is arranged to move from the first configuration to the third configuration by unilateral actuation of the second actuator.

That is, the second jaw may be as described with respect to the first jaw.

In one example, the set of jaws is coupled asymmetrically to the base. For example, if the first actuator comprises and/or is a wedge, the first jaw may be coupled to the base at an angle corresponding to the wedge, with respect to the second jaw.

In one example, the vice comprises the set of jaws comprising J jaws, including the first jaw and the second jaw, where J is a natural number greater than or equal to 2, for example 2, 3, 4, 5, 6, 7, 8, 9, 10 or more. The J jaws may be as described with respect to the first jaw and/or the second jaw. In one example, the set of jaws comprises a first subset of jaws, including the first jaw, and a second subset of jaws, including the second jaw, wherein the first subset of jaws comprises jaws as described with respect to the first jaw and the second subset of jaws comprises jaws as described with respect to the second jaw. In this way, a width of the workpiece to be supported by the vice may be increased and/or a force exerted on the workpiece increased and/or more uniformly distributed.

Contact surface The first jaw provides the first contact surface and the second jaw provides the second contact surface, wherein the first contact surface and the second contact surface are mutually opposed and transverse, preferably orthogonal, to the area At, , and wherein the first contact surface has the height hi, ,,, transverse, preferably orthogonal, to the area Ab, and the width wir 1. That is, the first contact surface and the second jaw are upstanding from the base. It should be understood that at least a part of the first contact surface and at least a part of the second contact surface contact opposed sides, respectively, of the workpiece, for example a door, in use, for example in the second configuration.

In one example, the first actuator provides the first contact surface. For example, if the wedge, a cam or a lever, the first contact surface may be provided by a respective surface or part thereof In this way, a complexity of the vice is reduced since the vice is arranged to move from the first configuration to the second configuration by unilateral actuation of the first actuator and the first actuator provides the first contact surface.

In one example, the vice comprises a set of jaw inserts including a first jaw insert providing the first contact surface. In one example, the first jaw insert comprises a recess, for example a groove, arranged to receive the workpiece therein.

Actuators The first jaw comprises the first actuator and the vice is arranged to move from the first configuration to the second configuration by unilateral actuation of the first actuator.

It should be understood that the unilateral actuation of the first actuator relates to or affects only one side of the jaws. Particularly, the unilateral actuation of the first actuator moves the first jaw and does not move the second jaw, notwithstanding that securing of the workpiece between the jaws imposes opposed forces on the first jaw and the second jaw.

In one example, the first actuator is arranged rearwardly of and/or extends rearwardly away from the first contact surface, for example arranged entirely rearwardly of and/or extends entirely rearwardly away from the first contact surface i.e. not towards the second contact surface. In other words, the first actuator does not span, partly or entirely, between the first contact surface and the second contact surface. In this way, the low profile base may be reduced in height further since the first actuator does not span under the workpiece.

In one example, the unilateral actuation of the first actuator urges the first contact surface to move, at least in part, in a direction transverse to the length /j, 1 between the first contact surface and the second contact surface. In one example, the direction is parallel to the width width wir of the first jaw (i.e. sideways) and/or towards the base (i.e. downwards). In this way, the workpiece may be secured against a stop and/or the base, for example i.e. a predetermined position. For example, if the first actuator comprises and/or is a wedge or a cam, actuation thereof urges the first contact surface to move towards the second contact surface and sideways and/or downwards, depending on an orientation and/or axis thereof.

In one example, the unilateral actuation of the first actuator comprises and/or is by applying a force f.1 on the first actuator in a direction parallel to the area 11,, of the polygon of support and/or in a direction transverse, preferably orthogonal, to the first length between the first contact surface and the second contact surface. For example, in use, the force A1 may be applied parallel to the workpiece (i.e. not towards), thereby preventing damage thereto during actuation. For example, if the first actuator comprises and/or is a wedge, the wedge may be knocked with a hammer parallel to the workpiece i.e. sideways.

In one example, the first actuator comprises and/or is a wedge, a cam or a lever. Such actuators are mechanically simple, reducing a complexity of the vice, and/or have low maintenance requirements. In addition, such actuators may be actuated manually, for example by hand and/or foot. Furthermore, such actuators may provide the first contact surface, as described previously. Generally, a greater extent of movement is provided by actuation of a wedge than a cam, for example. Cams are particularly beneficial when the workpieces are of consistent thickness while wedges allow greater variability in thickness thereof. In one example, the wedge is a removably coupled to the first jaw i.e. the wedge may be removed from and replaced, as required. In one example, the wedge is actuated by hitting with a hammer, for example. In one example, the cam is rotatably coupled to the base. In one example, the cam is actuated by standing on pedal attached thereto, for example. In one example, the lever is rotatably coupled to the base. In one example, the lever is actuated by standing on pedal attached thereto, for example.

In one example, the first actuator comprises and/or is a wedge having an angle in a range from 5° to 50°, preferably in a range from 10° to 40°, more preferably in a range from 15° to 30°, for example 20° or 25°. In this way, the workpiece may be securely supported in the vice.

Configurations The vice is arrangeable in: the first configuration, wherein the first contact surface and the second contact surface are spaced apart by the first length 1k a, wherein the first configuration is the open configuration and wherein the first length /ic 1 is the maximum spacing between the first contact surface and the second contact surface; and the second configuration, wherein the first contact surface and the second contact surface are spaced apart by the second length ij, :2, wherein the second configuration is the closed configuration.

The vice is arranged to move from the first configuration to the second configuration by unilateral actuation of the first actuator.

That is, the first contact surface and the second contact surface are arrangeable in a variably spaced relationship. It should be understood that the second length may correspond with (i.e. equal) a thickness of the workpiece supported by the vice.

Heights The ratio Rhe hr of the height h1 4 of the first contact surface to the height Hi, of the base is in a range from 2: 1 to 100: 1, preferably in a range from 5: 1 to 50: 1, more preferably in a range from 10: 1 to 25: 1.

In one example, the height Hb of the base is in a range from 1 mm to 12 mm, preferable in a range from 2 mm to 10 mm, more preferably in a range from 3 mm to 6 mm, for example 4 mm or 5 mm and/or wherein the height hic a of the first contact surface is in a range from 1 cm to 10 cm, preferably in a range from 2 cm to 8 cm, more preferably in a range from 3 cm to 6 cm.

In this way, the base may fit under a door during installation of thereof in a door frame, since the height Ht, of the base is sufficiently low. Typically, the gap under an installed door is in a range from about 3 mm to more than 30 mm, depending on whether and/or how the floor is finished, for example. In this way, pitching of the top of the door may be reduced further, since the height 11" a of the first contact surface of the first jaw is relatively large.

In one example, a height HI, of the vice, orthogonal to the area Ab is in a range from (Hb + hk,1) to 3/2 (Hb + a), preferably in a range from (Hb + hk 4) to 4/3 (rib + 4), more preferably in a range from (Hb + hit 4) to 5/4 (Hb + h1,1), most preferably (lib + hitt to 11/10 (Hi, + hi, ,i). That is, the overall height of the vice is substantially equal to, preferably equal, to the sum of the height of the base Fib and the height of the first jaw hic Areas In one example, a ratio Ra of the area Ab of the polygon of support to an area ak parallel thereto and between the first contact surface and the second contact surface in the first configuration, is in a range from 2: 1 to 100: 1, preferably in a range from 5: 1 to 50: 1, more preferably in a range from 10: 1 to 25: 1. In this way, the polygon of support is relatively large compared with the maximum size of workpiece that may be accommodated, thereby improving stability (i.e. pitching, rolling and/or yawing) of the workpiece, in use.

Widths In one example, the polygon of support has a width Wb, parallel to the width of the first contact surface, and wherein a ratio R" h of the width Wb of the polygon of support to the width WI of the first contact surface is in a range from 3: 2 to 50: 1, preferably in a range from 2: 1 to 25: 1, more preferably in a range from 5: 2 to 10: 1, for example about 3: 1. In this way, the polygon of support is relatively large compared with the width wa of the first contact surface, thereby reducing rolling of the workpiece, in use.

In one example, the width Wb of the polygon of support is in a range from 5 cm to 100 cm, preferably in a range from 10 cm to 75 cm, more preferably in a range from 15 cm to 50 cm, most preferably in a range from 20 cm to 40 cm, for example 30 cm and/or the width wit of the first contact surface is in range from 1 cm to 100 cm, preferably in a range from 2.5 cm to 75 cm, more preferably in a range from 5 cm to 50 cm, most preferably in a range from 7.5 cm to 25 cm, for example 10 cm, 15 cm or 20 cm.

Lengths In one example, the polygon of support has a length Lb, parallel to the length,1 between the first contact surface and the second contact surface in the first configuration, and wherein a ratio RI, h of the length Lb of the polygon of support to the length,,, between the first contact surface and the second contact surface in the first configuration is in a range from 3: 2 to 50: 1, preferably in a range from 2: 1 to 25: 1, more preferably in a range from 5: 2 to 10: 1, for example about 3: 1. In this way, the polygon of support is relatively large compared with the width wic of the first contact surface, thereby reducing pitching of the workpiece, in use.

In one example, the length Lb of the polygon of support is in a range from 5 cm to 100 cm, preferably in a range from 10 cm to 75 cm, more preferably in a range from 15 cm to 50 cm, most preferably in a range from 20 cm to 40 cm, for example 30 cm and/or the length tic 1 between the first contact surface and the second contact surface in the first configuration is in range from 1 cm to 100 cm, preferably in a range from 2.5 cm to 75 cm, more preferably in a range from 5 cm to 50 cm, most preferably in a range from 7.5 cm to 25 cm, for example 10 cm, 15 cm or 20 cm. Feet

In one example, the vice comprises a set of adjustable feet and/or a spirit level, for example attached to the base. In this way, the vice may be levelled and/or the workpiece aligned, for example vertically, in use. For example, by adjustment of the set of feet, differences in floor height across a doorway may be compensated for. In one example, the adjustable feet are provided on outriggers from the base, thereby increasing a size of the polygon of support while not increasing the height Hb.

In one example, the base comprises a set of wheels, for example attached to the base. In this way, the vice may be moved, for example translated, by rolling on wheels, so as to position and/or reposition the workpiece, for example align a door in a door frame. In one example, the set of wheels comprises a wheel, for example a plain wheel, a braked wheel or an adjustable height wheel and/or a caster wheel, for example a plain caster wheel, a braked caster wheel or an adjustable height caster wheel.

Passageway In one example, the base comprises a passageway (i.e. an aperture, a hole) therethrough, arranged between the first jaw and the second jaw. In this way, a workpiece, for example a length of pipe to be cut, may be inserted through the passageway and supported by clamping between the first jaw and the second jaw (i.e. against the first contact surface and the second contact surface thereof, respectively).

Auxiliary foot In one example, the base comprises an auxiliary foot, transverse, preferably orthogonal, to the base. That is, the auxiliary foot defines an auxiliary polygon of support transverse, preferably orthogonal, to the polygon of support having the area Ab. In this way, the vice may be oriented vertically, in use, on the auxiliary foot, so as to support of a workpiece, for example a length of pipe or wood, during sawing thereof.

Materials In one example, the vice is formed, at least in part, from a metal, such as steel, stainless steel and/or an aluminium alloy, and/or a composite, such as a fibre reinforced plastic, and/or wood, such as a hardwood or plywood. In one example, the vice is fabricated, at least in part, by welding, from such a metal.

In one example, the base comprises and/or is a planar base, provided by a sheet or plate material, for example a metal, such as steel, stainless steel and/or an aluminium alloy, and/or a composite, such as a fibre reinforced plastic, and/or wood, such as plywood.

Second aspect The second aspect provides a vice comprising: a base, wherein the base defines a polygon of support having an area Ab and has a height Hh orthogonal to the area AL, ; a set of jaws, including an actuatable first jaw and a second jaw, coupled to the base, wherein the first jaw comprises a first actuator, wherein the first jaw provides a first contact surface and the second jaw provides a second contact surface, wherein the first contact surface and the second contact surface are mutually opposed and transverse, preferably orthogonal, to the area Ab, and wherein the first contact surface has a height hi, ,I, transverse, preferably orthogonal, to the area Ab, and a width wk.1; wherein the vice is arrangeable in: a first configuration, wherein the first contact surface and the second contact surface are spaced apart by a first length tj,I, wherein the first configuration is an open configuration and wherein the first length is a maximum spacing between the first contact surface and the second contact surface; and a second configuration, wherein the first contact surface and the second contact surface are spaced apart by a second length tic,z, wherein the second configuration is a closed configuration; wherein the vice is arranged to move from the first configuration to the second configuration by unilateral actuation of the first actuator; and wherein the first actuator comprises and/or is a wedge having an angle in a range from 5° to 50°, preferably in a range from 10° to 40°, more preferably in a range from 15° to 30°, for example 20° or 25°, preferably wherein the first actuator provides the first contact surface.

In this way, the vice is arrangeable to support a workpiece W, by clamping between the first jaw and the second jaw (i.e. against the first contact surface and the second contact surface thereof, respectively).

The wedge is mechanically simple, reducing a complexity of the vice, and/or have low maintenance requirements. Wedges allow greater variability in thickness of the workpiece W. In addition, the wedge may be actuated manually, for example by hand and/or foot. In one example, the wedge is a removably coupled to the first jaw i.e. the wedge may be removed from and replaced, as required. In one example, the wedge is actuated by hitting with a hammer, for example. Furthermore, the wedge may provide the first contact surface. In this way, a complexity of the vice is further reduced since the vice is arranged to move from the first configuration to the second configuration by unilateral actuation of the first actuator and the first actuator provides the first contact surface.

The vice may be otherwise as described with respect to the first aspect.
