A snare drum strainer structure for a drum having a bottom drumhead, the strainer structure comprising:
- a first-side component comprising:
- a first mounting bracket configured to be mounted to one side of a drum shell near the bottom drumhead,
- a first slider received in an opening in the first mounting bracket for vertical movement with respect to the first mounting bracket, the first slider having a first adjustment/tension knob including a first threaded bolt, the first mounting bracket having a portion configured to clamp on a portion of the first slider,
- a first key bolt structure configured to releasably cause clamping of the first mounting bracket against the first slider,
- a first post having a portion received in an internal opening of the first slider and threadedly engaged with the first threaded bolt, and
- a first snare carrier fixed to the first post;
- a snare wire assembly including a plurality of wires extending between first and second ends thereof, the first end being received in the first snare carrier;
- and
- a second-side component comprising:
- a second mounting bracket configured to be mounted to a side of the drum shell near the bottom drumhead at a location diametrically opposed to the first mounting bracket,
- a second slider received in an opening in the second mounting bracket for vertical movement with respect to the second mounting bracket, the second slider having a second adjustment/tension knob including a second threaded bolt, the second mounting bracket having a portion configured to clamp on a portion of the second slider,
- a second key bolt structure configured to releasably cause clamping of the second mounting bracket against the second slider,
- a second post having a portion received in an internal opening of the second slider and threadedly engaged with the second threaded bolt, and
- a second snare carrier fixed to the second post, the second end of the snare wire assembly being received in the second snare carrier,
- wherein when the first side component and the second side component are mounted to the drum shell and with the first and second key bolt structures causing the first and second mounting brackets to clamp on the respective first and second siders, each disposed in a snare ON position with the snare wires pressed against the bottom drumhead, each key bolt structure can be manually rotated to release clamping of the first and second mounting brackets on the respective first and second siders so that each slider can be manually moved downwardly causing the wires to move away from the bottom drumhead to a snare OFF position, whereby an entire length of the wires can be kept parallel with the bottom drumhead in the snare OFF position.
A strainer for a snare drum having a bottom drumhead, the strainer comprising:
- a mounting bracket configured to be mounted to a side of a drum shell near the bottom drumhead,
- a slider received in an opening in the mounting bracket for vertical movement with respect to the mounting bracket, the slider having an adjustment/tension knob including a threaded bolt, the mounting bracket having a portion configured to clamp on a portion of the slider,
- a key bolt structure configured to releasably cause clamping of the mounting bracket against the slider,
- a post having a portion received in an internal opening of the slider threadedly engaged with the bolt, and
- a snare carrier fixed to the post, the snare carrier being configured to receive and carry an end of a snare wire assembly,
- whereby, when the key bolt structure is released and when the snare wire assembly is coupled to the snare carrier, the sider is configured to be manually moved vertically between 1) a snare ON position, such that wires of the snare wire assembly can engage with the bottom drumhead and 2) a snare OFF position such that the wires of the snare wire assembly can disengage with the bottom drumhead.
