Definitions
- the present invention relates to a powered sander, for example for use by carpenters/builders/decorators or persons carrying out do-it-yourself home improvement.
- the invention comprises a hand-held powered sander comprising: (a) a main body arranged to be held in the palm of the hand of a user; and (b) a strap attached, at least in use, to the main body at at least one attachment point and arranged to extend across at least part of the width of the back of the user's hand.
- the strap has a length sufficient to extend across the entirety of the width of the back of the user's hand.
- the strap is attached, at least in use, to the main body of the sander at at least two spaced-apart attachment points, preferably so that the hand is encircled by the strap extending across the back of the hand and the main body part held in the palm of the hand.
- one of the attachment points is situated adjacent to one edge of the hand (e.g. adjacent to the thumb) and the other attachment point is situated adjacent to the other edge of the hand (e.g. adjacent to the little finger).
- the strap is flexible.
- Preferred materials for the material of the strap include polymeric materials (including rubber, for example); woven fabrics (including webbing, for example); and the like.
- the strap may be substantially rigid, for example formed from a substantially rigid polymer material and/or metal and/or wood.
- the strap may be adjustable in length. This has the advantage of enabling the strap to be tightened (to the desired degree) around the back of the hand. It may also facilitate insertion of the hand under the strap and/or removal of the hand from under the strap, for example.
- the strap may consequently be formed from two (or more) sections joined or joinable together.
- a particularly preferred manner of making the strap adjustable in length is by incorporating loop-and-hook joining strips (e.g. VELCRO - trade mark) on opposing surfaces of two or more sections of the strap.
- the strap may include an adjustable buckle or the like.
- the strap forms a tight fight (preferably of the desired tightness according to the user's comfort) across the back of the user's hand.
- the tightness or looseness of the strap may be determined by means of the length of the strap being adjusted by the user.
- the strap is rotatably attached to the main body of the sander.
- the strap may be rotatably attached to the main body about an axis extending through both attachment points. This has the advantage of enabling the user to position the strap in a comfortable position across the back of the hand. It may also facilitate insertion of the user's hand under the strap and/or removal of the hand from under the strap.
- the rotatability of the strap with respect to the main body preferably enables the angle of the hand and/or arm of the user with respect to the main body to be varied during use, thereby enabling the sander to be used at a variety of angles (for example in order to sand awkward to reach surfaces).
- the main body of the sander preferably comprises a palm-receiving surface across which the strap extends.
- the palm-receiving surface is preferably convex in shape or otherwise contoured to fit comfortably and conveniently in the palm of a user's hand.
- the strap preferably enables the user to hold and use the sander in comfort and safety for prolonged periods.
- the strap preferably enables the user to hold the sander firmly substantially without needing to grip tightly the main body of the sander in the palm of the hand.
- the sander preferably is sized and shaped to facilitate its use by the elderly or disabled, for example.
- the main body preferably includes, at least in use, powered abrasive means situated on an opposite surface of the main body to the palm-receiving surface.
- the powered abrasive means preferably comprises a mount which is movable with respect to the main body of the sander and to which may be attached an abrasive element, for example sand paper, glass paper, emery paper, carborundum paper or the like.
- the abrasive element need not be based upon paper or card etc - substantially any abrasive means may be used.
- the abrasive element need not be attachable and detachable to the movable mount - it may be an integral part of the sander - but preferably the abrasive element is replaceable. Most preferably, however, the abrasive element is attachable to the movable mount by means of loop-and-hook joining pads (e.g. VELCRO- trade mark).
- the main body of the sander preferably includes a motor which drives the movement of the abrasive means with respect to the main body, in use.
- the motor is preferably an electric motor.
- the electric motor may be mains electricity and/or battery powered. In the latter case the main body preferably includes a battery storage cavity.
- the abrasive means may move with respect to the main body of the sander in substantially any suitable way to effect the desired sanding or abrading action.
- the abrasive means may rotate (driven by the motor) with respect to the main body.
- the sander is an orbital sander, and the movement of the abrasive means with respect to the main body is an orbital movement. This may be achieved, for example, by the abrasive means (preferably an abrasive element attached to a movable mount) being driven by the motor by means of an off-centre (or eccentric) shaft on which the abrasive means is mounted.
- the abrasive means is preferably attached to one or more flexible retaining members, and the combination of the off-centre shaft and the flexible retaining members cause the abrasive means to adopted a so-called orbital motion with respect to the main body of the sander.
- the main body of the sander preferably includes an on/off switch (and/or sanding speed adjust control) situated for convenience on a side surface of the main body part.
- switches and/or controls may be situated on two opposite side surfaces of the main body, for example symmetrically, in order to facilitate left and right-handed use.
- the strap is detachable and replaceable.
- the strap may be attached to the main body of the sander in either of two opposite orientations. This may facilitate adjustment of the length of the strap for example by, respectively, right-handed and left-handed users.
- Figure 1 shows a hand-held powered sander 1 according to the invention, comprising: (a) a main body 3 arranged to be held in the palm of the hand of a user; and (b) a strap 5 attached to the main body at two spaced-apart attachment points 7 (one of which is shown and the other is hidden from view) and arranged to extend across the width of the back of the user's hand (not shown).
- the strap 5 is adjustable in length; it is formed from two sections 5a and 5b joinable together by means of loop-and-hook joining strips (e.g. VELCRO - trade mark) on opposing surfaces 9 and 11 of the two sections of the strap.

Abstract
Description
- The present invention relates to a powered sander, for example for use by carpenters/builders/decorators or persons carrying out do-it-yourself home improvement.
- According to a first aspect, the invention comprises a hand-held powered sander comprising: (a) a main body arranged to be held in the palm of the hand of a user; and (b) a strap attached, at least in use, to the main body at at least one attachment point and arranged to extend across at least part of the width of the back of the user's hand.
- Preferably the strap has a length sufficient to extend across the entirety of the width of the back of the user's hand.
- More preferably, the strap is attached, at least in use, to the main body of the sander at at least two spaced-apart attachment points, preferably so that the hand is encircled by the strap extending across the back of the hand and the main body part held in the palm of the hand. Preferably, in use, one of the attachment points is situated adjacent to one edge of the hand (e.g. adjacent to the thumb) and the other attachment point is situated adjacent to the other edge of the hand (e.g. adjacent to the little finger).
- Preferably the strap is flexible. Preferred materials for the material of the strap include polymeric materials (including rubber, for example); woven fabrics (including webbing, for example); and the like. In alternative embodiments of the invention, the strap may be substantially rigid, for example formed from a substantially rigid polymer material and/or metal and/or wood.
- Advantageously, the strap may be adjustable in length. This has the advantage of enabling the strap to be tightened (to the desired degree) around the back of the hand. It may also facilitate insertion of the hand under the strap and/or removal of the hand from under the strap, for example. The strap may consequently be formed from two (or more) sections joined or joinable together. A particularly preferred manner of making the strap adjustable in length is by incorporating loop-and-hook joining strips (e.g. VELCRO - trade mark) on opposing surfaces of two or more sections of the strap. Additionally or alternatively the strap may include an adjustable buckle or the like.
- Preferably, in use, the strap forms a tight fight (preferably of the desired tightness according to the user's comfort) across the back of the user's hand. Advantageously the tightness or looseness of the strap may be determined by means of the length of the strap being adjusted by the user.
- In preferred embodiments of the invention the strap is rotatably attached to the main body of the sander. For example, in embodiments of the invention in which the strap is attached to the main body at two spaced apart attachment points, the strap may be rotatably attached to the main body about an axis extending through both attachment points. This has the advantage of enabling the user to position the strap in a comfortable position across the back of the hand. It may also facilitate insertion of the user's hand under the strap and/or removal of the hand from under the strap. The rotatability of the strap with respect to the main body preferably enables the angle of the hand and/or arm of the user with respect to the main body to be varied during use, thereby enabling the sander to be used at a variety of angles (for example in order to sand awkward to reach surfaces).
- The main body of the sander preferably comprises a palm-receiving surface across which the strap extends. The palm-receiving surface is preferably convex in shape or otherwise contoured to fit comfortably and conveniently in the palm of a user's hand.
- The strap preferably enables the user to hold and use the sander in comfort and safety for prolonged periods. In particular, the strap preferably enables the user to hold the sander firmly substantially without needing to grip tightly the main body of the sander in the palm of the hand.
- The sander preferably is sized and shaped to facilitate its use by the elderly or disabled, for example.
- The main body preferably includes, at least in use, powered abrasive means situated on an opposite surface of the main body to the palm-receiving surface. The powered abrasive means preferably comprises a mount which is movable with respect to the main body of the sander and to which may be attached an abrasive element, for example sand paper, glass paper, emery paper, carborundum paper or the like. The abrasive element need not be based upon paper or card etc - substantially any abrasive means may be used. The abrasive element need not be attachable and detachable to the movable mount - it may be an integral part of the sander - but preferably the abrasive element is replaceable. Most preferably, however, the abrasive element is attachable to the movable mount by means of loop-and-hook joining pads (e.g. VELCRO- trade mark).
- The main body of the sander preferably includes a motor which drives the movement of the abrasive means with respect to the main body, in use. The motor is preferably an electric motor. The electric motor may be mains electricity and/or battery powered. In the latter case the main body preferably includes a battery storage cavity.
- The abrasive means may move with respect to the main body of the sander in substantially any suitable way to effect the desired sanding or abrading action. For example, the abrasive means may rotate (driven by the motor) with respect to the main body. More preferably, however, the sander is an orbital sander, and the movement of the abrasive means with respect to the main body is an orbital movement. This may be achieved, for example, by the abrasive means (preferably an abrasive element attached to a movable mount) being driven by the motor by means of an off-centre (or eccentric) shaft on which the abrasive means is mounted. The abrasive means is preferably attached to one or more flexible retaining members, and the combination of the off-centre shaft and the flexible retaining members cause the abrasive means to adopted a so-called orbital motion with respect to the main body of the sander.
- The main body of the sander preferably includes an on/off switch (and/or sanding speed adjust control) situated for convenience on a side surface of the main body part. Advantageously, switches and/or controls may be situated on two opposite side surfaces of the main body, for example symmetrically, in order to facilitate left and right-handed use.
- Preferably the strap is detachable and replaceable. Advantageously, in preferred embodiments the strap may be attached to the main body of the sander in either of two opposite orientations. This may facilitate adjustment of the length of the strap for example by, respectively, right-handed and left-handed users.
- The invention will now be described, by way of example, with reference to the accompanying drawings, of which:
- Figure 1 shows, schematically, a first embodiment of a sander according to the invention;
- Figures 2 to 5 show, schematically, several views of a second embodiment of a sander according to the invention; and
- Figure 6 shows a detail of the second embodiment of the invention.

- Figure 1 shows a hand-held powered sander 1 according to the invention, comprising: (a) a
main body 3 arranged to be held in the palm of the hand of a user; and (b) astrap 5 attached to the main body at two spaced-apart attachment points 7 (one of which is shown and the other is hidden from view) and arranged to extend across the width of the back of the user's hand (not shown). - The
strap 5 is adjustable in length; it is formed from twosections 5a and 5b joinable together by means of loop-and-hook joining strips (e.g. VELCRO - trade mark) on opposing surfaces 9 and 11 of the two sections of the strap. In use, the strap may form a tight fight (preferably of the desired tightness according to the user's comfort) across the back of the user's hand by means of the length of the strap being adjusted by the user. - The main body has a convex curved, contoured external shape, to facilitate being held in the palm of one hand. An upper surface (as illustrated) 13 of the main body is a convex palm-receiving surface. On the opposite, underside (as illustrated) of the main body is abrasive means (not shown) - i.e. a movable abrasive element which carries out the sanding action.
- The main body contains an electrical motor which is powered by mains electricity - a
power cord 15 is shown. - Each of the two
opposite side surfaces 17 includes an on/off switch 19 - the sander is symmetrical for use in the left or right hand. - Figure 2 shows the first of several views of a second preferred embodiment of sander according to the invention. The sander 1 comprises a
main body 3 having a convex palm-receivingsurface 13 of generally ellipsoid shape arranged to be held in the palm of the hand of a user. Astrap 25 is attached to themain body 3 at two spaced-apart attachment points 7 which are located generally on the major axis of the ellipsoid.Removable attachment members 21 attach the strap to the main body. - The
strap 25 comprises a single continuous strip which is fixedly attached to afirst attachment point 7a, extends across the palm-receivingsurface 13 and is looped through the opposite attachment point 7b and folded back on itself.Surface 23 of thestrap 25 has suitably located loop-and-hook joining strips (e.g. VELCRO - trade mark) - not shown - by which the folded back portion 25b of thestrap 25 may be attached to the main portion 25a of the strap, and by which the length of the main portion of the strap between the attachment points may be adjusted. - The
attachment points 7a and 7b may be detached from the main body as shown in Figure 5(a). The orientation ofstrap 25 may be reversed to suit ease of adjustment for left or right handed users. - Also shown in Figure 2 is an on/off
switch 19 for the sander located symmetrically on a minor axis of the ellipsoid of the main body so that it is actuatable by the user's thumb irrespective of whether the user is right handed or left handed. Apower cord 15 is shown extending adjacent and below attachment point 7b. On the opposite of the main body, adjacent and belowattachment point 7a, is aremovable plug 27. When theplug 27 is removed (see Figure 6) it provides an aperture for the attachment of a vacuum hose for the removal of debris from within the sander due to the sanding process. - Figure 3 shows a reverse view of the sander shown in Figure 2. Air vents 20 are shown - air may be drawn into the main body via these vents when a vacuum hose is attached to
aperture 35 and actuated in use. - Figure 4 shows an end view of the sander of Figures 2 and 3, illustrating the fact that the attachment points enable rotational movement of the strap about the major axis of the main body ellipsoid, thereby enabling the position of the user's hand and/or wrist with respect to the main body to be varied.
- As previously mentioned, Figure 5(a) shows the sander with the strap and attachment points removed.
- Figure 5(b) shows the underside of the sander - the
movable mount 29 to which the abrasive element may be attached, is shown. - Figure 6 shows a detail of the
removable plug 27 referred to above. The plug includes a pair of resilientlyflexible detents 31 which are arranged to be received byrecesses 33 in theaperture 35. Therecesses 33 enable the plug to be pushed (substantially without rotation) fully into the aperture so that thedetents 31 of the plug engage on a rim 37 at the interior of the aperture. The plug is thereby prevented from being removed from the aperture until it is rotated through 90° and theplug detents 31 engage with recesses 39 in the rear rim 37 of the aperture, which enable the plug to be withdrawn from the aperture (substantially without further rotation).
