DETAILED DESCRIPTION

(12) With reference to FIG. 1 a drumstick in accordance with the present teachings is generally indicated at 10. The drumstick comprises multiple parts along its length, specifically a tip 12 that is rounded and intended to contact a drum or other instrument to cause that instrument to generate noise, a taper 14, a substantially cylindrical shaft 16 and a substantially cylindrical handle 18. The drumstick 10 terminates at the end remote from the tip 12 in an end cap 20 as discussed in more detail below.

(13) In this embodiment, the tip 12, taper 14 and shaft 16 are all integrally and monolithically formed from the same piece of material. Typically, this is achieved in an injection moulding process as discussed in more detail below. In other embodiments, this may not be the case, e.g. the tip 12 may be separately attachable onto the taper. In addition, in other embodiments, no cylindrical shaft may be provided, e.g. the handle may interface with the taper. Further, in this embodiment the tip 12, taper 14, and shaft 16 are formed from a transparent polycarbonate material, although in other embodiments may be formed from wood or other plastics material, for example.

(14) With reference to FIG. 7, the handle 18 is formed in this embodiment from a tube of the same or a similar diameter to that of the shaft 16, but defining a hollow space therein, as described in more detail below. In this embodiment the tube is aluminium. In other embodiments, the handle 18 may be formed from other materials such as other metals, plastics such as nylon or polycarbonate or composite materials such as carbon fibre and resin, the tubular shape may be formed by extrusion, deep drawing or bending of a flat sheet of material, for example.

(15) Finally, the end cap may also be made of a plastics material, as in this embodiment, or a suitable metal, e.g. aluminium.

(16) In this embodiment, the tip 12, taper 14 and shaft 16 define a first portion 22 and the handle 18 defines a second portion 24.

(17) Referring now to FIGS. 3 to 6, the drumstick 10 is shown in various states of assembly. In FIG. 3 the first portion 22 is visible, together with an extension thereof 26 which is received within the handle 18 and is therefore not visible in FIGS. 1 and 2. In addition, a screw 28 is depicted that is mounted to the extension 26. The extension 26 is also integrally and monolithically formed with the first portion 22, e.g. by injection moulding. As can be seen from FIGS. 3, 4 and 5 the extension comprises the following sections, starting from its connection to the shaft 16: a mounting portion 30, a light housing 32, a support 34 and a boss 36.

(18) The mounting section 30 is dimensioned to receive and support the handle 18 and in this embodiment includes two annular recesses 38 that are arranged to receive O-rings (not shown) and therefore both damp and seal the handle 18 to the first portion 22. The mounting section 30 also includes a stop 40 that in this embodiment is an area of increased diameter with respect to the shaft 16 in order to prevent the handle 18 from sliding any further down the first portion 22. In other embodiments the stop may simply be an annular end face of the shaft 16 such that the handle 18 and the shaft 16 are of the same overall diameter.

(19) The light housing 32 is a depression in the generally cylindrical body of the first portion 22 that is open on one radial face, and closed on two sides. An axial end wall 42 is provided at the end facing the first portion 22 and is rounded so as to receive the light emitting portion of an LED 44 (shown in phantom in FIG. 6). When the LED 44 is lit this enables the light to pass axially through the shaft 16, taper 14 and be emitted at the tip 12 and along its length. The support 34 is a relatively thin elongate portion that is arranged to sit proximate to an inner surface 45 of the tubular handle 18. As such, the support 34 provides a connection axially to the boss 36 whilst not consuming a significant amount of the space provided within the handle 18.

(20) The boss 36 extends transversely from the support 34 at its end remote from the first portion. The boss 36 is provided with a bore that extends axially, into which the screw 28 may be secured, in particular, the screw 28 may be self-tapping and the bore may act as a form of pilot hole, or a suitable threaded insert (not shown) may be provided in the bore to retain the screw.

(21) As can most clearly be seen in FIGS. 4, 5 and 6, the screw 28 is utilised to mount the end cap 20 to the extension 26 and therefore to the first portion 22.

(22) The end cap 20 comprises a section 46 that has a diameter substantially the same as that of the handle 18 (and stop 40), which therefore acts to confine the handle 18 between the head section 46 and the stop 40. Two arms 48 extend from the head 46 towards the extension 26 and have curved radially outer profiles which are shaped and dimensional so as to substantially conform to the inner surface 45. This further aids the stability of the drumstick 10 when assembled.

(23) A mouth 50 also is provided in the end cap 20 and, as can be seen from FIG. 6, is arranged to receive a printed circuit board (PCB) 52. As well as supporting the PCB 52 the mouth also has aperture 54 that extends through to the end face. This enables a switch 56 mounted on to the PCB to extend through to the end wall of the end cap 20 where a user can actuate the switch, e.g. to turn the light function on and off.

(24) As shown in the embodiment of FIG. 6, the PCB 52 is also arranged to mount four button cell batteries 58 within the space adjacent to the support 34, as well as the LED 44 using suitable mounts or cages 59. However, in alternative embodiments, there may be any suitable number of cell batteries. It will be appreciated that a hole is provided in the PCB 52 in order that it may fit over the boss 36. This further assists in the axial retention of the PCB 52. In addition, as shown in FIG. 6 a controller 60, e.g. a microprocessor controller, is mounted to the PCB in the space adjacent to the arms 48. Further, this space is also used to mount an inertial switch 62.

(25) In other embodiments this space, as well as the space adjacent to the support 34 may be used to additionally or alternatively mount other functional components such as accelerometers, gyroscopes, capacitors, re-chargeable batteries, motors or actuators to provide haptic feedback, power sockets, communication interfaces, or other functional components. For the embodiment depicted in FIGS. 1 to 6, assembly of the drumstick is achieved as follows:

(26) The first portion 22 is injection moulded and the second portion 24 is manufactured by extrusion, drawing or other suitable method. The batteries 58 are mounted to the PCB 52, which already has the controller 60, an inertial switch 62 and LED 44 mounted thereto (e.g. by soldering). The PCB 52 is then mounted to the extension 26 by the aperture 54 in the PCB being fitted over the boss 36 and the LED 44 being accommodated in the light housing 32. The O-rings are then fitted into the annular recesses 38 and the handle 18 is slid over the extension 26 until it abuts the stop 40. The end cap 20 is then slid within the space defined by the handle 18 such that the PCB is accommodated within the mouth 50 and the arms 48 are situated adjacent the boss 36.

(27) The screw 28 is then threaded into the boss 36 and tightened. The act of tightening the screw in effect clamps the axial ends of the handle 18 between the stop 40 and the head section 46. This stabilises the handle 18 on the first portion 22 so that relative movement between the first portion 22 and the second portion 24 is minimised. However, at the same time the O-rings (not shown) within the recesses 38 act to dampen the transmission of vibrations from the tip 12 through to the handle 18 when the drumstick 10 strikes a suitable percussion instrument. To use the drumstick 10, a drummer firstly turns on the lighting function by pressing switch 56. In a typical mode of operation, the inertial switch 62 is arranged such that when the drumstick 10 impacts a drum or other instrument this closes the circuit connecting the cells 58 to the LED 44 and causes the LED to become illuminated and emit the light through the first portion 22 and be emitted at the tip 12 and along the first portion 22.

(28) However, in more advanced versions of the drumstick 10 the controller 60 may control the colour of the light emitted by the LED, the duration of lighting, whether the lighting is continuous or flashing, for example.

(29) Further, in other variants the switch 56 may be operable to switch the drumstick 10 to operate in different modes, e.g. continuous lighting in a single colour or cycling through colours, for example. In a further variant, the inertial switch may be replaced by an accelerometer or gyroscope to provide more precise inputs to the controller 60 of the drumstick's 10 orientation or position in space. This may be utilised to further control how the light is emitted from the drumstick 10.

(30) In still further variants, the cells 58 may be replaced by a re-chargeable battery and a suitable charging interface may be provided on the end face of the end cap 20 to enable the re-chargeable battery to be charged. A suitable interface may be a micro USB or USB-C type connector.

(31) With reference in particular to FIGS. 5 and 6, it will be appreciated that various lengths of handle 18 can inherently be mounted to the first portion simply by using the screw 28 to adjust the position of the head section 46 relative to the stop. As such the shortest length of handle to be mounted would be that of a length where the mouth 50 of the end cap 20 abuts against the boss 36. Conversely, longer screws and end caps with longer arms 48 may be utilised to allow for a longer handle 18 without needing to change the mould tool used to mould the first portion 22. This therefore allows the drumstick 10 to be customised to particular user requirements without expensive re-tooling.

(32) Referring now to FIG. 8, a first portion 22 identical to that of the first embodiment is shown in enlarged plan view of the extension 26 thereof. However, in this embodiment the button cell batteries 58 are stacked in series with their planar end faces in contact with each other. The cells 58 are mounted to a smaller PCB 152 via end terminals 164. This arrangement of cells 58 is more compact in an axial direction than the arrangement depicted in FIG. 6, thereby enabling the PCB 152 to be significantly smaller or other functional components to be located in the space adjacent to the support 34.

(33) Referring to FIG. 9, like parts from previous figures described herein are denoted with the prefix 2. FIG. 9 depicts a further alternative embodiment where the first portion 222 has been reconfigured such that the support 234 is shortened and the boss 236 is therefore closer to the light housing 232 than in the first portion 22 of the first embodiment. Again, this allows a smaller PCB 252 to be used and optionally for the PCB to be provided with an aperture 266 to locate it thereon. This arrangement may allow for an even greater customisation of the length of the handle 18 as there is more scope for adjustment of the position of the end cap 20 relative to the boss 236.

(34) Referring to FIG. 10, like parts from previous figures described herein are denoted with the prefix 3. FIG. 10 illustrates a still further variant of the first portion 322 where the extension 326 is substantially the same as the extension 226 of FIG. 9 but the shaft 316 has been elongated by the introduction of a stop 340 that is substantially longer axially than that depicted in the first embodiment of FIGS. 1 to 6. As this portion is of a constant cross section, the injection moulding tool for the first portion 322 can be easily reconfigured to change the length of this portion without significant re-tooling costs. This therefore provides a further opportunity for customising the length and/or balance of the drumstick 310 of FIG. 10.

(35) It will be appreciated that numerous changes may be made within the scope of the present teachings. For example, the first portion may be manufactured from wood with a separate clear tip and clear light guide extending through the centre of the wood. Further, the tip may be frosted to alter the light emission. A handle may be formed from different tubular material such as tubular nylon or polycarbonate. The tip may be changed to be one that is mallet shaped or spherical and/or made of softer material. The drumstick may be adapted to become a foot pedal operated drumstick, the polycarbonate material may be dyed to be a different colour, may have UV fluorescent properties or be glow in the dark. The drumstick may additionally be able to output signals via BLUETOOTH or an interface, e.g. to allow the stick to play virtual drums in space and still create a sound via a speaker in conjunction with a suitable accelerometer and/or gyroscope. Further or alternatively the drumstick may incorporate its own sounder within the space of the handle, the drumstick may be configured such that the LED may be used in a particular mode to indicate the charged state of the batteries, e.g. by emitting a green light to indicate that the battery charge is good, amber that it is at an intermediate level, and red to show that the batteries are almost exhausted. Alternative arrangements may be used to secure the first and second portions together, e.g. complimentary threaded connections, bayonet-type fittings and/or adhesive. In further embodiments, the drumstick may be mounted to a foot pedal so as to strike a bass drum upon operation of the foot pedal.
