## Title
Rim riser

## Abstract

The claimed device is a drum rim extension. Previously, drummers playing cross-stick, (that is, laying the stick across the rim of the drum to produce a clicking or tapping sound), had difficulty maintaining a good grip on the drumstick and finding a consistent sound throughout performances. The drum rim extension is a block of metal, wood or plastic that connects to a portion of the rim of and drum and provides the player up to several inches of free space above the drum, improving stick handling and playing consistency. The drum rim extension improves drumming where rim playing is prominent in musical pieces.

TECHNICAL FIELD
The present invention relates to a drum rim rising device and some embodiments relate to a drum having a raised arc section of a drum rim.
BACKGROUND OF THE INVENTION
This invention relates to the need for accurate and consistent cross-stick playing, and, also addresses limitations in controlled acoustical sounds related to rim playing. This is due in part to the impossibility of a good grip on the drumstick. More particularly, it concerns an easily attachable, rim raising device that allows for a controlled accurate swing due to the allowance of a firmer grip on the drumstick.
Different drums have different acoustical properties, thus dramatically changing the cross stick sound, also, drum rims are very close to the playable drum head. The action of the drummer playing the head of the drum and switching to a cross stick sound requires a considerable amount of effort with very limited control.
BRIEF SUMMARY OF EMBODIMENTS OF THE INVENTION
It is the object of the invention to provide a solution to the problems described above. As will be seen, this device can be used in such a manner, as to further articulate cross stick playing, as well as enhance other areas of rim playing. With increased agility available to the player it opens up new acoustical possibilities.
A rim raising device is attachable to a drum, and includes,
A) A section of hard steel or hard synthetic material, solid or hallowed out, following the primary curvature of the arcuate rim, above the drum.
B) A mounting system, in which the presented device, fits onto the existing tension rods of a drum, and, is equipped with screws that tighten into threaded spacers. The device is held securely in place through its own torque.
As will be shown, another object is to provide the device as a molded configuration, with a section of the hoop sloping upward flattening out then descending, providing added cross stick playing space.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a fragmented view of a drum and one embodiment of the Rim Raising device;
FIG. 2 is a perspective view of the drum of FIG. 1 of a different embodiment of the invention;
FIG. 3 is a pre-molded embodiment as part of the existing drum rim; and
FIG. 4 illustrations one aspect in which an embodiment of the invention is applied (fitted for a singular tension rod).



DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION
Referring to FIG. 1, the rim raising device is primarily comprised of hard steel, wood or a hardened synthetic material with curvature in the arcuate direction above the drum 3 the attachment system is of a threaded material fitting onto the existing tuning rods of a drum 4 with tightening screws 1 and locking washers 5 device is secured through its own torque onto the drum.
Referring to FIG. 2, the rim raising device comprised of the same materials as in FIG. 2 attaches by way of spacers 4 device is flanged to align with the existing flanges on the drum's rim and extended tension rods 1 hold the device securely. Washers are added to ensure stability 3.
FIG. 3 illustrates a pre-molded configuration 1. The rim raising device is one complete unit with drum's rim.
Referring to FIG. 4, the Rim Raising device comprised of the same materials and would typically be a length of two to nine inches in length. As previously mentioned may also attach to a singular extended tension rod 1 and one spacer. The device is flanged to align with existing flange on the drum's rim. This illustration also demonstrates one advantageous way the invention works. The user is given more space between the drum's rim and the playable drum head for added agility.

## Claims

1. A drum rim raising device that is attachable to an existing drum structure, comprising:
an arc section of a drum rim configured to be secured to the existing drum housing;
