Abstract
A handle assembly for a power tool 1 comprises a housing 2 defining a handle 4 and housing a motor for actuating an output member of the tool, such as a drill bit or jigsaw blade. The handle assembly comprises at least one flexible sheet 8 adapted to be mounted to a surface of the handle of the power tool and having a series of protrusions 10 adapted to be engaged by a hand of a user of the tool. The protrusions 10 retain one or more blister packs (not shown) containing at least one vibration damping gel material between the flexible sheet 8 and the surface of the handle 4.
Description
- The present invention relates to handle assemblies for tools, and relates particularly, but not exclusively, to handle assemblies having combined friction gripping and vibration damping properties, for power tools in which an output shaft is driven by a motor.
- Known power tools, such as power drills in which a drill bit is rotated by an output shaft which is in turn rotated by means of an electric motor, generate significant amounts of vibration, which can under certain circumstances limit the length of time during which the tool can be used continuously. In addition, the housing of such tools is generally made from a durable plastics material on which it can be difficult for a user of the tool to maintain a grip when the tool is in use for a sustained period.
- U.S. Pat. No. 6,308,378 discloses a gripping arrangement for a handle of a power tool in which the sides of the handle are provided with frictional gripping zones, each side of the handle including a plurality of alternating gripping zones of a softer material and a harder material. The softer material used is generally a thermoplastic elastomer or rubber material, and the harder material is generally the same material as that from which the tool housing is formed.
- This known arrangement suffers from the drawback that because the softer material performs the dual functions of providing a friction grip and vibration damping, the choice of material constitutes a compromise in that although it will have acceptable friction reducing and vibration damping properties, the performance of the handle is limited because a material having optimum frictional properties will generally have unacceptable vibration damping properties, and vice versa.
- WO02/38341 discloses a grip handle for a hand-held machine tool in which a hand grip is separated from the remainder of the housing by a vibration damping element consisting of an inflatable annular air filled cushion. An additional handle is provided which has a tubular grip element surrounding a further annular air cushion.
- This known arrangement suffers from the drawback that the vibration damping properties of air can only be varied by adjusting the air pressure within a chamber containing the air, and even then, the range of vibration damping properties achievable is limited. Furthermore, it is difficult, and therefore expensive, to manufacture a sealed chamber containing air having a predetermined pressure.
- Preferred embodiments of the present invention seek to overcome the above disadvantages of the prior art.
- According to an aspect of the present invention, there is provided a gripping portion for a power tool having a housing and a motor within said housing for actuating an output member of the tool, the gripping portion adapted to be engaged by a hand of a user of the tool and comprising:
-
- at least one blister pack comprising respective first and second flexible sheets defining at least one gel-containing chamber therebetween, wherein the or each said gel-containing chamber contains a vibration damping gel material and said first and second sheets are sealed to each other at the periphery of the or each said gel containing chamber; and
- at least one clamping member for clamping at least one said blister pack to said housing and having at least one aperture therethrough such that at least one said gel-containing chamber protrudes in use through a respective said aperture and substantially none of said vibration damping gel is located in use between a said clamping member and the housing.
- By providing at least one flexible member and at least one chamber containing at least one vibration damping gel material between the engaging portion and the surface of the handle in use, this provides the advantage of enabling the material of the flexible member to be chosen to have the optimum frictional properties to enable a user to maintain a grip on the tool, and the vibration damping gel material at the same time to have the optimum vibration damping properties. In particular, it is possible to provide gel materials having a wide range of vibration damping properties compared with air. This also provides the advantage of simplifying construction of the assembly, which in turn reduces the cost of manufacture of the assembly, as well as providing the advantage of further reducing the cost of manufacture of the assembly by providing one or more components which perform more than one function.
- At least one said blister pack may be foldable.
- This provides the advantage of enabling the blister pack to conform to the shape of the tool handle.
- At least one said blister pack may be perforated between at least one pair of adjacent chambers.
- This provides the advantage of facilitating folding of the blister pack.
- At least one said blister pack may further comprise locating means for enabling the blister pack to be mounted to a support.
- Said locating means may comprise at least one aperture through said blister pack at a respective location remote from the or each said chamber.
- The assembly may further comprise support means adapted to be located on a side of at least one said blister pack remote from the corresponding said engaging portion.
- At least one said chamber containing the or each said gel material may be at least partially transparent in use.
- This provides the advantage of enabling visible indicia, such as decorative features or trade marks, or electrical indicators, for example indicating that the tool of which the assembly forms part is actuated, to be seen while the tool is in use.
- The assembly may further comprise at least one visible indicium located in at least one said chamber.
- At least one said visible indicium may be electrically operated in use.
- This provides the advantage of enabling said indicium to provide an indication of an operating condition of a power tool, such as whether the tool is actuated.
- At least one said indicium may be at least one light emitting diode.
- The assembly may further comprise at least one electrical switch for actuating the tool.
- This provides the advantage of simplifying assembly of the tool, which in turn further reduces the cost of manufacture of the tool.
- According to another aspect of the present invention, there is provided a tool comprising:
-
- a housing;
- a motor within the housing adapted to actuate an output member of the tool; and
- a gripping portion as defined above.
- Said gripping portion may have an outer surface including at least one material of higher coefficient of friction than the material of the housing of the tool.
- Preferred embodiments of the invention will now be described, by way of example only and not in any limitative sense, with reference to the accompanying drawings, in which:

housing 2 is formed from a generally durable plastics material, as will be familiar to persons skilled in the art, and has a recessed portion 5 on a generally smooth upper surface of thehandle 4, the recessed portion 5 being provided with arecess 6 containing an actuating switch (not shown) for turning the tool 1 on and off. Thehousing 2 is provided withventilation apertures 7 at one end of the recessed portion 5 to allow cooling of the interior of thehousing 2. - A
flexible sheet 8, of thermoplastic elastomeric material, such as a thin layer of polyurethane, having a coefficient of friction higher than that of the material from which thehousing 2 is made, is formed by means of a suitable method such as moulding. Thesheet 8 has a periphery shaped to fit inside the periphery of recessed portion 5 to cover all of the recessed portion 5 except that part in which theventilation apertures 7 are provided, and theflexible sheet 8 is provided with a through-aperture 9 to allow access to the actuating switch inrecess 6. Theflexible sheet 8 is also provided with a series ofprotrusions 10, each of which defines a chamber between thesheet 8 and the upper surface of thehandle 4 of thehousing 2 when thesheet 8 is placed in position on the upper surface of the recessed portion 5. Each of the chambers underneath theprotrusions 10 accommodates a vibration damping gel contained in a blister pack 20 (FIGS. 3A to 3C). Alternatively, theflexible sheet 8 may be bonded to a backing sheet (not shown) to define the chambers containing the vibration damping gel. - A cover plate 11 of durable plastics material, such as the material from which the
housing 2 is constructed, has aninternal surface 12 corresponding generally to the external (i.e. upper) surface of theflexible sheet 8. The cover plate 11 is provided with a series offirst apertures 13 for allowing theprotrusions 10 of thesheet 8 to protrude therethrough when the plate 11 is mounted to thehandle 4 to secure theflexible sheet 8 in place, asecond aperture 14 co-operating with the aperture 9 to allow access to the actuating switch inrecess 6, and a series ofthird apertures 15 cooperating with theventilation apertures 7 in thehousing 2. - Referring now to
FIG. 3A , agel blister pack 20 for use in the embodiment ofFIGS. 1 and 2 is formed from a thin,flexible backing piece 21 of thermoplastic polyurethane film on which one ormore pieces 22 of a vibration damping gel formed from a semi-solid silicone rubber or polyurethane material are provided. Thepieces 22 of gel may be translucent and/or semi transparent and/or coloured, for reasons which will be explained in greater detail below. Thebacking layer 21 with thepieces 22 of gel are then covered by a generallytransparent layer 23 of thin, thermoplastic polyurethane film, which is pulled down tightly over thegel pieces 22 by means of a combination of heat and pressure, and then secured to thebacking piece 21 at theperiphery 24 of eachgel piece 22 to form discrete chambers encapsulating each gel piece by suitable welding techniques, such as heat staking and/or ultrasonic vibration, which will be familiar to persons skilled in the art. Alternatively, thegel material 22 can be poured or injected into a pre-formedtransparent sheet 23 and then covered by backingpiece 21 and welded. The upper surface of thebacking piece 21 may be printed with decorative or trade mark information which is visible through thetransparent layer 23 andgel 22. - Referring to
FIG. 3B , in which parts common to the embodiment ofFIG. 3A are denoted by like reference numerals but increased by 100 and will therefore not be described in greater detail herein, thebacking piece 121 of theblister pack 120 is provided with a series of raisedportions 125 which may be decorative matter and/or trade marks or raised lettering. The raisedportions 125 define recesses 126, which may accommodate light emitting diodes which can be illuminated to provide a visual indication of an operating parameter of the tool incorporating theblister pack 120, for example to indicate whether the tool is switched on. - In the arrangement of
FIG. 3C , in which parts common to the embodiment ofFIG. 3B are denoted by like reference numerals but increased by 100, the raisedportions 225 definingrecesses 226 may be formed by aseparate layer 227, which is encapsulated along withgel material 222 bytransparent sheet 223 andbacking piece 221. - The operation of the
handle 4 of the tool 1 of FIGS. 1 to 3 will now be described. - When a user's hand (not shown) grips the tool 1 when in use, the user's hand comes into contact with the cover plate 11 and the
protrusions 10 beneath which one ormore blister packs tool housing 2 are damped by the vibration damping gel underneathprotrusions 10, and the user's grip on the tool is maintained by contact between the user's hand and the high friction material of theflexible sheet 8. It can therefore be seen that by suitable choice of material of theflexible sheet 8, the frictional properties of thesheet 8 can be optimized, while the vibration damping properties of the gel-filledblister packs - Referring to
