Abstract
A latch and catch arrangement is disclosed, whereby a sleeve supporting a flexible hinge with an extended finger is oriented over a fluid connection to a socket guide. An alignment via a latch and catch between the sleeve and tool collar orients a flexible hinge, which may be of reduced thickness, over a bearing in a guide. The finger moves upward when a tool is inserted into a tool socket, and the flexible hinge, properly oriented by the alignment catch/latch, keeps the finger in the tool socket while allowing necessary movement to insert and remove a tool.
Claims18
A tool mount with flexible finger connector comprising:
- a tool collar with a closed back end and an open front and an outer annular wall and an open ended tool socket having an inner annular wall;
- a bearing guide with a fluid connection from the outer annular wall to the inner annular wall;
- a generally cylindrical sleeve with an outer annular wall and inner annular wall having an open end, a partially closed end;
- a flexible hinge formed in the sleeve, fluidly connecting the outer and inner annular walls with a fixed first end and a free second end and a finger extending from the second end towards the interior of the cylindrical sleeve;
- the sleeve fitted over the tool collar with the finger extending into the tool socket through the bearing guide;
- and,
- a shaft attached to the closed back end of the tool collar.
A tool mount with flexible finger connector comprising:
- a tool collar with a closed back end and an open front and an outer annular wall and an open ended tool socket having an inner annular wall;
- a guide with a fluid connection from the outer annular wall to the inner annular wall;
- a generally cylindrical sleeve with an outer annular wall and inner annular wall defining an interior, having an open end and a partially closed end wherein the sleeve is fitted over the tool collar;
- a flexible hinge flap with a free end formed within an aperture in the sleeve wherein the aperture fluidly connects the outer and inner annular walls;
- a finger extending from the free end towards the interior of the cylindrical sleeve;
- a shaft attached to the closed back end of the tool collar;
- and, wherein the finger protrudes through the guide into the tool socket and may be displaced by insertion of a tool into the tool socket.
A method of reversibly attaching tools, the method comprising:
- forming a flexible hinge on a cylindrical sleeve with a guide surrounding a portion of the hinge, the guide forming a passageway through the sleeve and forming a finger on the free end of the hinge oriented toward the center of the cylindrical sleeve;
- placing the sleeve around a tool collar, the tool collar comprising;
- an axial tool socket;
- a bearing guide generally perpendicular to the tool socket;
- orienting the flexible hinge around the tool socket whereby the finger is positioned over the bearing guide and extends into the tool socket;
- inserting a tool shaft with shaped proximal end and tool guide formed therein, into the tool socket;
- and, using force to move the finger with the proximal end of the tool whereby the finger moves away from the tool socket to become momentarily displaced by the tool shaft and allow passage of the tool shaft.
A method of reversibly attaching tools, the method comprising:
- forming a linear tool collar with an open front end and a shaft extended from a back end;
- forming an axial tool socket in the tool collar through the front end;
- forming a flexible hinge arm connected to the tool collar at one end with a second free end and within a guide fluidly connecting the exterior of the tool collar with the tool socket;
- forming a finger near the shaped second free end and extending into the tool socket;
- inserting a tool shaft with shaped proximal end and tool guide formed therein, into the tool socket;
- and, using force to move the finger with the proximal end of the tool whereby the finger moves away from the tool socket with the flexible hinge arm to become momentarily displaced by the tool shaft and allow passage of the tool shaft.
