BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a work bench, and also to a supporting arm suitable
for attachment to a work bench.
2. Description of the Related Art
[0002] Work benches are used for supporting tools and workpieces in an elevated position
to allow a user to easily work on a workpiece without bending to ground level. Such
benches are used commonly in a variety of situations, ranging from use in a domestic
home workshop, to a commercial factory setting, and are typically sturdy in construction
comprising of a supporting framework and a planar top forming a work surface. Examples
are known from
CN202878278U,
GB2339275A,
US5577817A or
US6061866A.
[0003] Typical operations performed on a work bench include cutting, drilling, sanding,
welding and hammering of a work piece. A problem is therefore encountered using work
benches common in prior art, in that such operations on a work piece tends to result
in production of environmental pollutants. Such pollutants include physical contaminants
such as noxious fumes, dust, material shavings, and sparks, in addition to non-physical
contaminants such as high noise levels. These pollutants can be particularly problematic
in the commercial manufacturing environment, in which a large number of work benches
may be housed in a single factory, each work bench producing pollutants such as dust
and noise. It is common then in such facilities for every worker in a factory to be
required to wear protective eye, ear and nose wear, to avoid exposure to the pollutants
generated, even if the worker is not working at a work bench.
[0004] An approach to solving this problem is to provide each work bench with a
hood extending around the rear and top of the work bench, and having side walls extending
along the side edges of the bench, to at least partially contain pollutants produced
by operations performed on the bench. However, such hoods tend to restrict an operative's
access to the surface of the work bench. Further, it is common to use work benches
to work on work pieces that are longer in length that the width of the bench, for
example, planks of wood or long lengths of piping, and so the ends of the work piece
extend further than the sides of the work surface. Existing work benches incorporating
hoods compensate for this by forming cut outs in the side walls of the hood, such
that a long workpiece may rest on the work surface with its ends extending outwardly
of the work bench through the cut outs in the side walls of the hood.
[0005] However, a problem is still encountered in loading long work pieces on to the work
surface of the work bench, as the side walls prevent placing of the work piece onto
the work surface in the normal manner, it instead being necessary to feed the work
piece in through the cut out of one side wall, slide the work piece along the work
surface, and through the cut out on the opposing side wall. Consequently, although
work benches of the prior art incorporating a hood may be effective in containing
pollutants, they are difficult to use, and make loading of a work piece onto the work
surface particularly difficult.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
Figure 1
[0035] A work bench 101 according to a specific embodiment of the present invention is illustrated
in Figure 1. In the present example, the work bench is configured as a self contained
work station, being one of a number of such stations located in a factory, and is
being used by an operative 102 to perform a work operation on workpiece 103. It will
of course be appreciated however that a work bench such as bench 101 may be deployed
in a variety of environments, and alternative work benches embodying the present invention
are instead configured for use within a domestic workshop environment. In a further
alternative embodiment, a work bench embodying the present invention is configured
for use within a commercial kitchen environment for the purpose of preparing food,
where it is found to have utility in containing odours and vapours generated by food
stuffs being cooked on a heating device located on the work surface of the bench.
[0036] As illustrated in the Figure, the work bench 101 comprises of a top member 104, a
supporting framework 105 which supports the top member 104 in an elevated position
relative to ground surface 106, and a canopy indicated generally at 107. In the embodiment,
top member 104 comprises of a substantially planar sheet having first and second side
edges 108, 109, a front edge 110, and a back edge 111, and has an upper surface 112
which defines a generally rectangular working surface. The top member is supported
by framework 105 at a convenient height from ground level for operative 102 to work
on work surface 112.
[0037] Work surface 112 thus presents a surface on which operative 102 may conveniently
support workpiece 103 and the required tools whilst performing a manufacturing process
on the workpiece. It is envisaged, that work bench 101 may be used in conjunction
with power operated tools, for example, an electric circular saw, which may be installed
on the work surface 112 either on a permanent or temporary basis.
[0038] In the specific embodiment, framework 105 includes a base 113, a back wall 114, and
side walls 115, 116, defining respectively three sides of an enclosure beneath the
top member 104. The enclosure defined by framework 105 may be used for storage of
tools, equipment and accessories used by an operative with the work bench. Indeed,
enclosure 105 may be used to store tools whilst the operative is away from the workbench,
and so in the specific embodiment the enclosure is further provided with a pair of
closable doors 117, 118, each said door being hingedly connected at an edge to a respective
side wall 115, 116. Doors 117, 118 each include a handle 119 on their front surface
and incorporate a locking mechanism to enable the doors to be secured in the closed
configuration illustrated, in which access to the interior of the enclosure is prevented.
[0039] A number of suitable locking mechanisms will be well known to the skilled person,
for example, a sliding bar locking mechanism, in which a bar is slidably connected
to the interior of each door, and on actuation is brought into engagement with the
lower surface of the top member 104, or the upper (internal) surface of the base 113,
thereby preventing unauthorised access to tools and equipment contained inside the
enclosure. It will of course be appreciated, that supporting framework 105 may take
many alternative forms depending on the particular configuration of the work bench.
Indeed, in a simpler embodiment, supporting framework 105 comprises of a plurality
of tubular legs each located at a corner of the workbench in the manner of a conventional
table.
[0040] At the base end, framework 105 is supported by four castor wheels 120, positioned
at each corner of the framework, which enable the work bench to be rolled across a
ground surface. In the specific embodiment, one pair of the castor wheels are rotatable
about their axis and lockable so as to prevent undesired movement, whilst the remaining
pair of castors are fixed, non-steering, wheels.
[0041] Work bench 101 is further provided with a canopy indicated generally at 107, which
is releasably attached to the supporting framework 105, and extends upwardly of the
work surface 112 and partially about the perimeter of the work surface. Canopy 107
comprises of a back wall 121 extending upwardly from adjacent the back edge 111 of
the top member 104, from a base end releasably connected to the supporting framework
105, to a top end, and which extends substantially along the full length of the back
edge 111 of the top member 104 between said first and second side edges 108, 109.
Canopy 107 further comprises first and second side walls 122, 123 which are joined
at their rear edge to the back wall 121, and extend forwardly from the back wall towards
the front edge 110 of the top member 112.
[0042] In the specific embodiment, said first and second side walls project forwardly from
said back wall 121 along planes that are respectively aligned with said first and
second side edges 108, 109, each said side wall 122, 123, having a lower edge 124,
125, and terminating in a forward edge 126, 127 closest to the front edge 110 of the
top member 104. In the embodiment, said side walls 122, 123 define generally rectangular
panels and are arranged such that the lower edge 124, 125, of each wall extends substantially
parallel to the upper surface 112 of the top member 104. Said first and second side
walls 122, 123, are arranged to extend forwardly, generally orthogonally from said
back wall towards a plane aligned vertically with the front edge 110 of the top member
104, leaving a distance between the lower edge of each said side wall 122, 123, and
the upper surface 112 of the top member 104. In this way, a gap is defined below each
said side wall which extends from directly below the forward edge of each side wall,
rearwardly partly along the length of each side wall towards the back wall 121. In
this case, the forward edge 126, 127 follows a plane that is substantially parallel
to the front edge 110 of the top member 104, and meets with the lower edge 124, 125
the vertex 128, 129, defined between the lower edge 124, 125 and the forward edge
126, 127, of each said side wall 122, 123, and so a gap is defined between the lower
edge of each side wall and the upper surface of the top member at the vertex 128,
129, the gap then extending rearwardly along substantially the full length of each
side wall, towards the back wall 121.
[0043] In the specific embodiment, each said side wall 122, 123 is configured to extend
substantially the full depth of the work bench, i.e. substantially the full distance
between said rear edge 111 and said front edge 110 of said top member 104. Thus, in
the embodiment, the forward edge 126, 127 of each said side wall 122, 123 is configured
to be substantially vertically aligned with the front edge 110 of said top member
104. More particularly, in the specific embodiment, the vertex 128, 129 of each said
side wall is configured to be substantially vertically aligned with said front edge
110 of said top member 104. as will be understood, in the specific embodiment, the
forward edge 126, 127 of each said side wall extend along a plane that is vertically
aligned with the front edge 110 of said top member 104. It will of course be appreciated
that in alternative embodiments the forward edge of each side wall may extend along
a plane that is not vertically aligned with the front edge of the top member.
[0044] Thus, canopy 107 acts to partly enclose the worksurface 112, with the front of the
canopy left open to allow an operative access to the worksurface, and a gap 131, 132
defined between the lower edge of each said side wall and the worksurface 112, extending
from the forward surface of each side wall, rearwardly towards the back wall 121.
In effect, the gap acts as a cutout in the side walls, in which a lower portion of
the forward edge 126, 127 of each side wall is removed, and a cut out extends therefrom
rearwardly towards the back wall 121. This cut out allows easy loading of a workpiece
on to the work surface 112, as will be described further with reference to Figure
2.
[0045] It will of course be appreciated that in although in the specific embodiment illustrated,
each side wall 122, 123 extends along a plane aligned vertically with each said side
edge 108, 109 of the top member 104, in alternative embodiments, the side walls may
extend forwardly 'inboard' of the side edges of the top member, such that only a central
portion of the top member is enclosed by the side walls, with the side edges of the
top member extending outwardly of each side wall.
[0046] In the specific embodiment illustrated, canopy 107 further comprises a roof member
130 located at the top end of the back wall 121 and side walls 122, 123, and arranged
to extend across the working surface 122. The roof member 107 thus presents a ceiling
to the area enclosed by the canopy, preventing the escape of pollutants upwardly from
the workbench.
[0047] In the embodiment, canopy 107 is constructed in two sections. Said back wall 121
and said first and second side walls 122, 123 are formed of a single section of sheet
metal material, pressed to define a generally U-shaped section, and said roof member
is formed of a second section of pressed metal, the various sections being connected
by suitable attachment means, for example, bolts. The canopy itself when so constructed
is then releasably attachable to the top member 104 or the supporting framework 105,
again using any convenient means, for example, bolts. This construction of the releasably
attachable canopy facilitates easy transport and storage of the work bench.
[0048] The material construction of the work bench 101 will be entirely familiar to those
skilled in the art, in as much that the walls 121, 122, 123, and roof member 130,
are all constructed from a sheet metal material, which is in the specific embodiment,
two millimetre thickness sheet steel. The walls of the supporting frame work 105 are
constructed from the same sheet steel, and the top member 104 from thicker, five millimetre,
sheet steel. It will of course be appreciated however the exact materials used to
construct the work bench may be varied according to the specific application for which
it is intended. Indeed, in alternative embodiments, the sections of the work bench
may be constructed from plastics or even wood fibre based materials.
Figure 2
[0049] The work bench 101 shown previously with reference to Figure 1 is shown in use in
Figure 2.
[0050] As shown, operative 102 has loaded a workpiece 103 onto the work surface 112. Work
piece 103 is relatively longer in length than the width of the work bench 101, and
so the ends of the work piece extend over the first and second side edges 108, 109
of the top member respectively. In work benches of the prior art incorporating a hood
having side walls that extend along the side edges of the top member without leaving
a gap between the lower edge of each side wall and the upper surface of the top member
below the forward edge of each side wall, loading of the work piece would be problematic,
as the forward edge of the side walls would meet with the top member, thus preventing
the workpiece from being loaded onto the work surface lengthways. Instead, it would
be necessary to manipulate the work piece onto the work surface around the forward
edge of each side wall, or else feed the workpiece through a cut out in a side wall
from the side of the work bench, along the work surface, and through a cut out in
the opposing side wall.
[0051] When the work piece is placed on the work surface 112 as illustrated, it may be worked
as necessary, for example, using a tool such as a motorised circular saw, or an electric
drill, mounted on the work surface 112. It will of course be appreciated that such
working of a work piece may result in the production of pollutants such as noise and
dust. Whilst these pollutants would be generally contained by the back wall 121, side
walls 122, 123, and roof member 130, pollutants may be allowed to escape away from
the station through the open front of the canopy, or through the gaps 131, 132, defined
between the lower edges 124, 125, of each said side wall and the upper surface 112
of the top member 104.
[0052] In order to prevent escape of pollutants in this way, in the specific embodiment
illustrated, the canopy is further equipped with strip curtains 201, 202, 203, which
cover respectively the gaps 131, 132, and the open front of the canopy 107. Said strip
curtains 201, 202 each comprise of a plurality of elongate strips of a flexible material,
for example, flexible Polyvinyl Chloride (PVC), which are connected adjacent a respective
lower edge 124, 125, of each side wall, and are arranged to extend downwardly under
the force of gravity towards the upper surface 112 of the top member 104.
[0053] In the specific embodiment illustrated, the plurality of elongate strips extend along
substantially the full length of the lower edge 124, 125, of each said first and second
side walls, so as to effectively close the gap 131, 132 defined between the lower
edge and the upper surface 112 of the top member 104. In the embodiment, roof member
130 is also provided with a strip curtain 203 substantially similar in construction
to strip curtains 201, 202, connected adjacent the forward edge of the roof member
and extending along substantially the full length of the forward edge. Strip curtain
203 is illustrated extending only a short distance downwardly from the underside of
the roof member 130 so as to avoid unnecessarily obscuring the interior of the canopy
from view, although it will of course be appreciated that in practice the plurality
of elongate strips of curtain 203 will extend down the full height of the front opening
to almost meet the upper surface 112 of the top member 104. In the embodiment, the
curtains 201, 202, 203 are constructed of a transparent, anti-static PVC material,
having a high fire resistance rating.
[0054] Of course, the flexible elongate strips are easily displaced when loading the work
piece 103 on to the work surface 112, and so do not impede loading of a workpiece,
and then conform readily about the profile of the work piece.
[0055] As illustrated, work bench 101 further includes a vice member, in the form of drop
vice 204, configured for releasable engagement with a work piece positioned on the
working surface 112. Thus, the vice member is movable between the disengaged position
shown, downwardly into engagement with the workpiece, so as to press the workpiece
against the working surface and prevent unwanted lateral movement of the workpiece
relative to the working surface 112, when the work piece is being worked on.
[0056] Figure 2 further illustrates supporting arms 205 which extend outwardly of the work
bench parallel to the long axis of the top member 104. Supporting arms 205 are configured
for supporting a work piece located on the work surface 112, at positions either side
of the top member, to prevent the workpiece from tilting downwardly at either end.
In the embodiment, supporting arms 205 are substantially identical, and comprise of
an elongate strut 206 slidably received in a socket 207 fixed to said supporting framework.
In this way, supporting arms 205 are slidably movable between the retracted configuration
shown in Figure 1 and the extended configuration shown in Figure 2.
[0057] In the extended configuration, each said supporting arm extends from a base end 208
proximal the supporting frame work, to a distal end 209. In the specific embodiment,
each said supporting arm 205 further comprises a ground engaging support leg 210 arranged
proximal said distal end of the arm, the support leg being configured for engagement
with the ground surface to provide additional support to the supporting arm and prevent
the supporting arm from sagging downwardly along its length. The supporting arms 205
and support legs 210, will be described further with reference to Figures 4a and 4b.
[0058] As will be described further with reference to Figures 3a and 3b, the work bench
is equipped with electrical components, including electric lighting and an electric
power take-off socket. These electric components draw power from an external power
source via a common power input socket 211. Power input socket 211 is installed in
a channel protruding inwardly from the back wall 121 of the canopy, such that the
socket body does not protrude farther than the back wall 121, thereby preventing damage
occurring to the socket in use, and allowing the work bench to be located with its
back wall 121 abutted against a wall of a building for example. The socket body is
selected such that the axis of the socket is inclined relative to the back wall 121,
such that the cable 212 of an input plug inserted in the socket falls downwardly from
the socket, thereby minimising the likelihood of the cable presenting a trip hazard.
Figures 3a & 3b
[0059] The work bench 101 is shown in a front elevation view in Figure 3a and in a side
elevation view in Figure 3b. In these views the strip curtain 203 is omitted from
view for clarity.
[0060] Referring to Figure 3a, it can be seen that the work bench 101 comprises a lighting
device 301 configured to illuminate the interior of the canopy 107 and the work surface
112. In the embodiment, lighting device 301 comprises an array of light emitting diode
(LED) components installed within a housing that is sealed to prevent the passage
of vapour therethrough. Lighting device 301 draws power from the common power input
211 through a permanently closed (non-switched) electrical circuit. In this way, lighting
device 301 automatically lluminates when the common power input 211 is connected to
an external power source, signalling to an operative that the work bench is correctly
connected to a power source.
[0061] Work bench 101 further includes a switched power take-off socket 302 secured to the
internal surface of the back wall 121, the socket 302 drawing power from common power
input 211. In this way, an operative may connect power input leads for electrically
operated tools et cetera to the socket 302.
[0062] Vice member 204 is depicted in the Figures attached to the internal surface of the
second side wall 123. As shown, vice member 124 comprises of an elongate shaft 303
which is slidably received in a bracket 304 mounted to the interior of the side wall
123, and a head portion 305. The shaft 303 is thus slidable within the bracket 304
so as to bring the head portion into engagement with a workpiece located on the work
surface, thereby clamping the workpiece to the work surface and preventing unwanted
movement of the work piece.
[0063] Work bench 101 further comprises a vibration absorbing mat 306 arranged to cover
said working surface 112 of the top member 104. In the embodiment, vibration absorbing
mat 306 comprises of a sheet of resiliently compressible rubber material, configured
to absorb vibrations produced when working on a workpiece located on the working surface
112. Similarly, the internal surfaces of the side walls 122, 123, back wall 121, and
roof member 130, include a sound insulating material laid on the surface, configured
to attenuate sound vibrations produced inside the canopy, preventing their transmission
outwardly of the canopy. In the embodiment, a sound attenuating material is used having
a high fire resistance rating, such that the material is not easily ignited by sparks
or exposure to heat.
[0064] Canopy 107 is further provided with a vent aperture 307 through the back wall, the
aperture being partially occluded in the illustration by a grille. Vent aperture is
configured to allow attachment of a vacuum device to the rear surface of the back
wall 121, to facilitate extraction of air from within the canopy 107, to facilitate
removal and subsequent isolation of air borne contaminants such as dust produced within
the canopy.
[0065] Referring particularly to Figure 3b, it can be seen that the lower edge 124, 125,
of the side walls 122, 123 of the canopy extends substantially parallel to the upper
surface of the top member 112, thereby defining a gap between the lower surface 124,
125 of the side wall, and the upper surface 112 of the top member 104 that is substantially
uniform in height along the depth of the work bench. It will of course be appreciated
however that the lower edges 124, 125, may alternatively extend along a plane that
is not parallel with the upper surface of the top member 112. Indeed, in an alternative
embodiment the forward edge and lower edge of the side wall may be curved in form,
and thus the height of the gap 131, 132, may vary along the length of the lower edge
124, 125.
[0066] As shown clearly in Figure 3b, a gap is defined between the lower edge 124, 125,
of each side wall 122, 123, below the forward edge 126, 127, from the vertex 128,
129, where the lower edge joins the forward edge 126, 127, and the gap extends substantially
the full depth of the top member almost to the back wall 121. This is advantageous
as it allows a workpiece to be easily located on the working surface 112 of the top
member 104, and slid rearwardly until the work piece is almost in contact with the
interior of the back wall 121, which is useful in the event that the work piece is
great in depth.
[0067] It will of course be appreciated however that the work bench might alternatively
be configured such that the gap between the lower edge 124, 125, of the side wall
122, 123 and the upper surface 112 of the top member 104, extends only a short distance
along the side edge 108, 109, of the top member, from the vertex 128, 129 towards
the back wall 121. Although unsuitable for accepting work pieces having a great depth,
such an arrangement would be suitable for work pieces with a relatively shorter depth,
for example, pipework.
Figure 4
[0068] The supporting arm 205 described previously with reference to Figure 2 is shown in
perspective view in Figure 4a, and its associated support leg 210 is shown in isolation
in an exploded view in Figure 4b.
[0069] Referring to Figure 4a, the supporting arm includes an elongate shaft part 206, configured
for connection at a base end to the framework of a work bench, to extend towards a
distal end. Thus, elongate shaft 206 is slidably received in the bracket 207 forming
a part of the supporting framework, such that the supporting arm may be extended and
retracted by inserting or retracting the elongate shaft 206 from within the enclosure
defined by the supporting frame work. In the specific embodiment, the brackets 207
are further provided with spring loaded index pins, configured to engage in corresponding
apertures defined by the elongate shaft 206 proximal said base end, to lock the supporting
arm in the fully extended position and prevent the elongate shaft from being fully
withdrawn from the bracket 207.
[0070] In the specific embodiment, the supporting arm is further equipped with a height
adjustable ground engaging support leg 210, located proximal the distal end of the
elongate shaft, and configured for engagement with a ground surface to provide additional
support to the supporting arm. In the embodiment, said support leg 205 is received
in a bracket 401 at the distal end of the elongate shaft 206.
[0071] As depicted in Figure 4b, in the specific embodiment, the support leg comprises of
first and second elongate hollow tubular members 404, 405, the first said elongate
member being slidably received in said second elongate member 405. In this way, the
overall length of the support leg 205 may be adjusted as necessary by inserting or
retracting the first elongate member from the second elongate member, and the length
may then be fixed using turnscrew 406 which passes through the second elongate member
405 and engages the first elongate member 404, preventing relative movement there
between.
[0072] At an upper end of the support leg 205, is a rolling bearing 402, which in the embodiment
is a cylindrical roller rotatably mounted to the upper end of the support leg. The
rolling bearing 402 is configured for engagement with a work piece, to allow the workpiece
to be drawn easily across the support leg during repositioning of the work piece,
as may be required in the event that a work piece is to be cut into multiple lengths.
The support leg 205 extends generally downwardly from the supporting arm towards a
base end 403 configured for engagement with a ground surface.
