DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0044] Preferred embodiments of the present invention and advantages will now be described herein by reference to FIGS. 1 to 3B of the drawings. By way of example, embodiments of the present invention may be implemented in the form of a saxophone type instrument configuration (100), a clarinet-type instrument having a single-reed configuration (101), and, a flute-type instrument having a cross-blowing lip plate (102) as shown in FIG. 1.

[0045] In embodiments of the present invention an elongate tubular body (200) is provided having a plurality of tone holes (201) extending through the surface of the elongate tubular body (200). The elongate tubular body (200) may for instance be molded from a resin material or any other suitable material. The tone holes (201) in the exemplary embodiments may typically include diameters approximately in the range of between 4 mm-10 mm depending upon the type of instrument implemented. In certain embodiments, such as where a saxophone-type instrument is implemented, the tone holes may be up to around 50 mm in diameter.

[0046] The preferred embodiments also include a plurality of key members (202) corresponding to each of the tone holes (201). The key members (202) each include an attachment portion (202A) and a closure portion (202B) which are integrally molded from an elastomeric polymeric material such as silicone or a silicone-based material. It is possible in certain embodiments for the key members to be formed from a suitably shaped and dimensioned co-polymeric material, polymeric composite material, or a non-polymeric material.

[0047] The attachment portions (202A) of the key members (202) include locating holes (202D) disposed therein which are configured to receive corresponding locating pins extending from the elongate tubular body (200) so as to locate the key members (202) in fixed positions on the elongate tubular body (200) adjacent to their corresponding tone holes (201). Key members (202) are further held in place by a stopper plate (204) which are configured for releasable attachment with the elongate tubular body (200) by for instance friction-fitting engagement. The stopper plate (204), when releasably engaged with the elongate tubular body (200), sandwiches the attachment portion (202A) of the key member (202) securely in place against the outer surface of the elongate tubular body (200) such as is shown in FIGS. 2 and 3A. In alternate embodiments, the attachment portion (202A) could be attached to the elongate tubular body (200) by any other suitable manner of attachment including for instance an adhesive attachment, screwed-in attachment and clamped attachment.

[0048] Conveniently, key members (202) are able to be selectably removed for maintenance or replaced entirely when worn out simply by urging the stopper plate (204) away from the elongate tubular body (200) to release the stopper plate (204) from the elongate tubular body (200) and then sliding the key member (202) of the locating pins. In certain embodiments, key members (202) may be provided in a selection of different colours such that a user may conveniently customise the coloured key members (202) that are attached to the elongate tube member. Colour customisation of key members (202) may be useful as a visual learning aid for a child who may more readily remember the key to be operated during playing of the instrument. In yet alternate embodiments, key members (202) may include indicia visible to the user which may represent a musical note corresponding to the tone hole that the key member is configured to cover. Replacement key members (202) may also be provided of variable shapes and dimensions in seeking to accommodate a range of different user finger shapes and sizes.

[0049] The closure portions (202B) of the key members (200) are pivotably movable relative to the attachment portions (202A) around a pivot region (202C) between at least one of a closed configuration in which the closure portion substantially seals the corresponding tone hole (201), and, an opened configuration in which the closure portion (202B) is spaced apart from the tone hole (201) wherein the tone hole (201) is opened. The material and shape/dimensioning of the closure portion (202B) allows the corresponding tone hole (201) to be accurately and firmly sealed by the closure portion (202B) when arranged in the closed configuration. By way of comparison, multi-component/multi-material key assemblies of existing instruments such as flutes and the like may typically utilise felt pads disposed on the keys to contact with the rim of the tone hole to seal the tone hole. However, over time, felt-pads tend to deteriorate and compress to the point where their ability to provide a tight seal over the tone hole is compromised. Additionally, deterioration and compression of the felt-pads on keys of existing instruments tends to result in a loss of tactile feel and responsiveness experienced by the user.

[0050] The integrally formed attachment portion (202A) and closure portion (202B) are configured such that the closure portion (202B) is biased towards the opened configuration when attached to the elongate tubular body (200). In these preferred embodiments, the inherent biasing of the key member when at rest is provided by virtue of the material used to form the key member (202), in this case being silicone, and the structure of the key member (202). When a user presses downward on a given key member (202), the key member (202) substantially seals the tone hole (thereby changing the pitch of the instrument) to allow playing of a note. When the user releases his finger from the key member (202), the key member (202) is urged back to the opened configuration by its inherent biasing. The properties (including density and hardness) of the silicone used to integrally form the key member (202) is selected so as to allow for suitable responsiveness of the key member (202) in being able to rapidly seal and open the tone hole (201) during playing of the instrument. Conveniently, this responsiveness of the key members (202) facilitates playing of a “trill” on the instrument.

[0051] The stopper plate (204) is configured to assist in maintaining the closure portion (202B) at a fixed clearance of approximately 4.5 mm from the tone hole (201) when arranged in the opened configuration. This clearance is considered to provide suitable sound projection and accuracy of pitch when the tone hole (201) is opened during playing of the instrument. In certain embodiments, the stopper plate (204) need not assist in maintaining the closure portion (202B) at the fixed clearance distance and the fixed clearance distance may be achieved simply by selectively configuring the shape and dimensions of the key member (202) itself.

[0052] As shown, the structure of the key members (202) may also be integrally formed with either a single closure portion configured for covering a single tone hole (201), or, a plurality of integrally formed closure portions which are configured to cover a plurality of tone holes (201) when pressure is applied to the key member (202) by a user's finger(s). For instance, in FIG. 3B, a key member (202) is shown with integrally formed from silicone with multiple closure portions configured for covering adjoining tone holes (201).

[0053] Certain half-note key members (300) such as is shown in FIG. 1 may include an aperture (301) extending therethrough which allows for half-notes to be played using the instrument. The aperture (301) is sized and dimensioned such that when arranged in the closed configuration, the aperture (301) is aligned over the tone hole (201) whereby a half-note is able to be played. The aperture (301) extending through the closure portion may for instance include a diameter approximately in the range of between 2 mm-6 mm.

[0054] Those skilled in the art will appreciate that the invention described herein is susceptible to variations and modifications other than those specifically described without departing from the scope of the invention. All such variations and modification which become apparent to persons skilled in the art, should be considered to fall within the spirit and scope of the invention as broadly hereinbefore described. It is to be understood that the invention includes all such variations and modifications. The invention also includes all of the steps and features, referred or indicated in the specification, individually or collectively, and any and all combinations of any two or more of said steps or features.

[0055] The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that that prior art forms part of the common general knowledge.
