US 5,025,699 A · Finger rest for recorder

Abstract

A finger rest for a recorder, which is attached on the under side of a body of the recorder for facilitating support of the weight of the recorder body with a thumb of the right hand of a player, comprises a body holding section having a bottom portion of a predetermined length in the longitudinal direction of the recorder body and side portions on both sides of the bottom portion, and a thumb supporting section projecting from the holding section downward in the direction perpendicular to the longitudinal direction of the body holding section. The body holding section has a cross section in the form of an arc so as to engage the outer periphery of the recorder body with a spring force. The arc is a major arc having a circumference longer than that of a half circle. When the finger rest is engaged over the outer periphery of the recorder body, the thumb of the right hand of a player can be stably supported on the downwardly projecting thumb supporting section to thereby facilitate movement of other fingers which are used to open/close ring keys. The finger rest may be freely adjusted positionally by moving it along the length of the recorder body to suit a player.

a body holding section having a bottom portion extending a predetermined length in the longitudinal direction of the recorder body, and respective side portions extending from said bottom portion on both sides of said body holding section;
a thumb supporting section projecting from said body holding section downward in a direction substantially perpendicular to said longitudinal direction of said recorder body and of said body holding section;
said body holding section having a sectional shape in the form of an arc when viewed in the cross sectional direction of said recorder body so as to hold said recorder body firmly and tightly with a spring force;
at least a portion of said body holding section being resilient, and said body holding section having an inner diameter smaller than the outer diameter of said recorder body, an arc extending over the inner surfaces of said bottom portion and said side portions being a major arc which is larger than the length of a half circle;
said thumb supporting section comprising a plate-like member which has a plane substantially parallel to the cross section of said arc section of said body holding section;
and
said plate-like member having a width W so as to extend the bottom portion of said body holding section and over to said two side portions of said body holding section which define said arc section.
