## Background
The present invention relates to an apparatus for mounting one or more percussion instruments, such as a cymbal, bell, or gong, onto a stand.
BACKGROUND OF THE INVENTION
Cymbals are a common percussion instrument. The cymbals that are played by drummers in a band or orchestra are conventionally mounted onto a cymbal stand. To assist in being mounted, a cymbal has a centrally located, circular aperture that is sized to fit around an externally threaded cylindrical portion of the cymbal stand.
Most cymbal stands have legs which rest on the ground and a shaft which extends vertically from the legs. In some instances the cymbal is mounted onto the uppermost portion of the vertical shaft, while in other cases, the cymbal is mounted onto one end of a boom arm that is attached to the vertical shaft so as to position the cymbal closer to the drummer.
The conventional method of mounting a cymbal onto a stand involves the following steps. First, a plastic sleeve with an outwardly projecting rim is fitted over the lower end of the externally threaded portion of the shaft. A felt washer is then slipped over the plastic sleeve to sit on the rim of the sleeve, followed by the cymbal. A second felt washer is then placed over the cymbal and a wing nut screwed down upon the upper felt washer to hold the cymbal onto the cymbal stand.
This well known method of mounting a cymbal onto a stand suffers from several disadvantages. For example, the time taken to securely mount a cymbal onto a stand or to detach a securely mounted cymbal can be lengthy; the wing nut can be over-tightened and consequently cause damage to the cymbal when played; and the small nature of the separate parts involved means that the parts frequently get misplaced.
Quick-release fixtures to attach a cymbal onto a cymbal stand are known in the art, for example, U.S. Pat. No. 4,526,083 describes such a cymbal mounting fixture.
However, there are a number of difficulties and/or disadvantages associated with the cymbal mounting fixtures of the prior art, including that the fixture is susceptible to working itself loose and detaching itself from the cymbal stand as the cymbal is played.
It is an object of the invention to provide a percussion instrument mounting apparatus that will overcome at least some of the abovementioned difficulties and/or disadvantages.

As shown in FIG. 1, the apparatus is designed to allow a cymbal 10 to be quickly and securely attached to or detached from a cymbal stand 11. However, it will be understood that the apparatus could be used to mount any other suitable percussive instrument onto a stand. The cymbal and the stand are both conventional items, with the cymbal having a circular mounting aperture in the centre of the cymbal and the cymbal stand having an externally threaded cylindrical portion for use in mounting the cymbal.
The apparatus comprises a support portion and a retaining portion, the support portion comprising a support member 12 arranged for attachment to the stand 11 and including a shaft 12b, the retaining portion comprising a gripping member having a pair of elements, 14a and 14b, spaced apart from each other and one or more spreader means, 21 or 23, arranged to urge the spaced apart elements away from each other, wherein the support and retaining portions are adapted to mount the percussion instrument therebetween, the shaft engageable with the retaining portion, the elements of the gripping member normally biased to a first position that is capable of retaining the shaft between the elements in a locked position in the said retaining portion, the elements movable to a second position in which the retaining portion can be received on or removed from the first position on the shaft, the elements movable from the first position to the second position by activation of the or each spreader means.
The mounting of the cymbal to the stand by means of the apparatus may be described as follows. First, the support member 12 is secured onto the cymbal stand 11. As shown in FIG. 2, the support member is an elongated body with a proximal end and a distal end. Extending longitudinally from an opening at the proximal end is a cylindrical coupling 12a having an internally threaded bore 12c. A cylindrical portion of the cymbal stand 11 with an external screw thread may be threadedly engaged in the coupling bore 12c to secure the support element 12 to the cymbal stand.
At the distal end of the support member 12 is a cylindrical shaft 12b which extends longitudinally from a shoulder 12d of the body of the support member, the surface of the shoulder being perpendicular to the axis of the shaft. The shaft 12b is of a constant diameter throughout the length of the shaft except for a neck 12e positioned near the distal end of the shaft, the neck being a circumferential groove cut into the shaft. At the most distal portion of the shaft, beyond the neck, is a tapered tip 12f. The support member may be made of any suitable metal or alloy, such as steel.
As shown in FIG. 3, an elongated hollow cylindrical sleeve 15 having a first end and a second end is placed over the shaft 12b of the support member. The first end of the sleeve has an externally threaded portion 15a adapted to engage with an internally threaded channel 13c in a locking part 13 in the retaining portion. The second end of the sleeve has an outwardly projecting rim 15b arranged to sit on the shoulder 12d of the support member. The sleeve may be made of any suitable material or combination of materials, such as metal for the first end and plastic for the rim. Two felt washers 16, 17 are placed over the first end of the sleeve to sit on the rim of the sleeve, followed by the cymbal 10.
The neck 12e and tip 12f of the shaft are arranged to engage with the locking part in the retaining portion above the cymbal 10. The locking part 13 consists of two principal sections, namely a dome-shaped cap 13a having a cylindrically recessed underside; and an annular base 13b with a centrally located channel 13c for receiving the free end of the shaft 12b, the base being sized to fit within the recess of the cap. The two sections of the locking part may be made of any suitable metal or alloy, such as steel. A felt washer 18 is fixed to the base 13b of the locking part to provide flexible cushioning for the cymbal 10 so that the cymbal can vibrate after being struck during the course of being played. The cap 13a is movable relative to the base 13b of the locking part and the release mechanism may be activated by pressing, pulling or rotating the cap 13a of the locking part.
FIGS. 3 through 8 show an embodiment of the apparatus in which the release mechanism is activated by pressing the cap. FIGS. 3, 4 and 5 show the apparatus in its ‘locked’ state with the elements of the gripping member, 14a and 14b, in the closed position and the shaft 12b being retained in a locked position in the locking part 13. FIGS. 6, 7 and 8 show the apparatus in its ‘unlocked’ state with the gripping member elements 14a and 14b in the release position in which the shaft 12b can be received in or retracted from the locking position within the locking part 13.
As shown in FIG. 3, the cap 13a is biased away from the base 13b by a spring member 19 attached to an elongated guide pin 20 (two of the four guide pins are shown). Each guide pin has opposing ends, one end having a wider diameter than the other end. The narrow end 20a of each guide pin is fixed to the cap 13a. The wide end 20b of each guide pin is movably housed within a recess inside the base 13b. When the cap 13a of the locking part is pressed to unlock the apparatus, the spring members 19 are compressed and the cap is brought into closer proximity to the base 13b (shown in FIG. 6).
Best shown in FIG. 5, the gripping member comprises a pair of mutually spaced apart parallel flexible spring rods 14a and 14b, each rod being positioned on opposing sides of the centre of the channel 13c in the locking part to receive the shaft 12b, the spacing of the rods in the closed position being capable of retaining the shaft in the locking position by gripping the neck 12e of the shaft, the release mechanism being configured, upon activation, to increase the distance between at least a portion of both rods and to move the rods into the release position (shown in FIG. 8).
As shown in FIG. 4, the spreader means comprises two tapered protrusions 21 mounted to the underside of the cap 13a. Each protrusion is arranged, upon activation, to engage with a corresponding recess 22 between the parallel rods 14a and 14b of the gripping member on the base 13b and configured to increase the distance between at least a portion of both rods (as shown in FIG. 7) so that the shaft 12b can be received in or retracted from the locked position within the locking part 13.
FIGS. 9 through 14 show another embodiment of the apparatus in which the release mechanism is activated by pulling the cap 13a. FIGS. 9, 10 and 11 show the apparatus in its ‘locked’ state with the gripping member elements 14a and 14b in the closed position and the shaft 12b being retained in a locked position in the locking part 13. FIGS. 12, 13 and 14 show the apparatus in its ‘unlocked’ state with the gripping member elements 14a and 14b in the release position in which the shaft 12b can be received in or retracted from the locking position within the locking part 13.
Unlike in the first embodiment, the cap 13a, as shown in FIG. 9, is biased towards the base 13b by a spring member 19 attached to an elongated guide pin 20 (two of the four guide pins are shown). Each guide pin has opposing ends, one end having a wider diameter than the other end. The narrow end 20a of each guide pin is fixed to the underside of the cap 13a. The wide end 20b of each guide pin is movably housed within a recess inside the base 13b together with the spring member 19. When the cap 13a of the locking part is pulled to unlock the apparatus, the spring members 19 are compressed and the cap is moved further apart from the base 13b (shown in FIG. 12).
As shown in FIG. 10, the spreader means comprises two elongated activator pins 23. Each activator pin has opposing ends, one end having a wider diameter than the other end. The narrow end 23a of each activator pin is fixed to the underside of the cap 13a. The wide end 23b of each activator pin is movably housed within a recess 24 inside the base 13b and configured, upon activation, to increase the distance between at least a portion of both rods of the gripping member (as shown in FIG. 13) so that the shaft 12b can be received in or retracted from the locked position within the locking part 13.
FIGS. 15 through 18 show a further embodiment of the apparatus in which the release mechanism is activated by rotating the cap 13a about the stationary base 13b. FIGS. 15 and 16 show the apparatus in its ‘locked’ state with the gripping member elements 14a and 14b in the closed position and the shaft 12b being retained in a locked position in the locking part 13. FIGS. 17 and 18 show the apparatus in its ‘unlocked’ state with the gripping member elements 14a and 14b in the release position in which the shaft 12b can be received in or retracted from the locked position within the locking part 13.
As shown in FIG. 15, the spreader means comprises two elongated activator pins 23. Each activator pin has opposing ends, one end 23a is fixed to the underside of the cap 13a and the other end 23b is free to move within a circular indentation 25 in the base 13b. The free end of each pin abuts a free end of a rod 14a or 14b of the gripping member on the base 13b and is configured, upon activation, to increase the distance between at least a portion of both rods of the gripping member (as shown in FIG. 18) so that the shaft 12b can be received in or retracted from the locked position within the locking part 13.
The apparatus allows for the quick release of the shaft 12b from the locked position within the locking part 13 when the spreader means is activated. Importantly the apparatus is not susceptible to working itself loose and detaching itself from the cymbal stand 11 as the cymbal 10 is played. Because the locking part sits on the shoulder 12d of the support member 12 in the mounted position, the locking part can rotate freely about the shaft of the support member without the risk of detachment.
While some preferred aspects of the invention have been described by way of example, it should be appreciated that modifications and/or improvements can occur without departing from the scope of the invention as set out in this specification.
The terms comprise, comprises, comprising, or comprised, if and when used herein, should be interpreted non-exclusively, that is, as conveying “consisting of or including”.
