Abstract

To adjust the tension on the snare of a drum head, one end of the snare is supported to an adjustment device, including a base on the drum trunk, a slide guided for movement vertically along the base and the snare is attached to the movable slide. First and second switches are pivotable on the base between off and on positions. Two shafts are attached to the slide. A respective link leads from each switch to a lifting member on the shaft and moving up of the switch moves the lifting member to raise the shaft to raise the slide to a varying extent depending upon the height of an adjustment nut on each of the shaft. The nuts on the two share adjustable for setting high tension and low tension on the snare.

Claims

1. A device for adjusting and switching the tension of a snare on a drum head, comprising:

a drum having a drum trunk, a drum head at an end of the drum trunk, a snare extending across the drum head including a first end supported to the drum and including a second end supported to the adjustment device such that operation of the adjustment device adjusts and switches the tension of the snare across the drum head;

the adjustment device comprising;

a base attached to the drum trunk;

the base including a vertical motion guide;

a slide supported for vertical motion on the vertical motion guide of the base;

an installation part on the slide including elements for holding the second end of the snare and selectively tensioning the snare as the slide moves with respect to the base;

a first and a second position adjustment member fixed to the slide and movable therewith, an adjustment element on each of the position adjustment members and being adjustable between a more elevated high tension position and a lowered lower terrain position;

a respective first and second link for the first and second adjustment members, each link being pivotable at the respective adjustment member;

a respective first and second switch lever, each switch lever having a respective first pivot connection with a respective one of the first and second links, the switch levers having a respective second connection with the base such that each switch lever is movable between a lowered off and an upraised on position;

movement of each switch lever to the respective on position operates the respective link to engage the respective position adjustment member such that elevation of at least one of the position adjustment members by the respective link elevates the slide to the respective height position set by the respective adjustment element on the respective position adjustment member and such that movement of each switch lever to the off position removes the raising of the respective position adjustment member toward the adjustment element and enables the slide to be lowered and reduces the tension on the snare.

2. The device of claim 1, wherein the second connection of each of switches is a pivot connection to the base so that the respective movement of each switch pivoting between the on and off positions.

3. The device of claim 2, wherein the pivot axis of each of the switches is transverse to the direction of sliding of the slide.

4. The device of claim 1, wherein each position adjustment member attached to the slide comprises a shaft on which the respective adjustment element is disposed;

a respective lifting member on and movable along each of the shafts, each of the links being connected with the respective lifting member, whereby the link engages the adjustment element through the respective lifting member.

5. The device of claim 4, wherein each of the shafts has a screw threaded region, and the respective adjustment element comprises an adjustment nut on the screw threaded region and adjustable therealong for controlling the extent of movement of the lifting member, the movement of the link and the permissible movement of the slide.

6. The device of claim 2, further comprising an intensification member between the base and the slide normally urging the slide to move in the direction for the reducing the tension of the snare.

7. The device of claim 2, wherein the first ones of the switching lever, the link and the adjustment element are for setting a low tension position for the slide and for the snare and the second ones of the switching lever, the link and the adjustment element are for setting a high tension position for the snare.

8. The device of claim 7, wherein each position adjustment member attached to the slide comprises a shaft on which the respective adjustment element is disposed;

a respective lifting member on and movable along each of the shafts, each of the links being connected with the respective lifting member, whereby the link engages the adjustment element through the respective lifting member.

9. The device of claim 8, wherein adjusted positions of the adjustment elements, the links and the switches are selected so that the slide has different respective positions with respect to the base for no tension, low tension, and high tension of the snare.

10. The device of claim 3, further comprising cooperating engagement parts positioned on the first and second switch levers so that the first switch lever for low tension can be operated on and off without operating the second switch lever for high tension to the on position while the operation of the second switch lever to the on position also moves the first switch lever to the on position.

11. The device of claim 3, wherein the vertical motion guide comprises an axle on the base extending vertically along the drum trunk, and the slide being movable along the axle.
