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.

First claim

The invention claimed is:

1. 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.

2. The tool mount with flexible connector of claim 1 , wherein said flexible hinge is one of “U” shaped and “C” shaped.

3. The tool mount with flexible connector of claim 1 , further comprising an alignment positioning catch on the tool collar.

4. The tool mount of claim 3 , wherein an alignment guide is one of a latch and a catch.

5. The tool mount of claim 4 , wherein the alignment positioning catch further comprises:
a partially closed latch at the back end of the sleeve;
a positioning catch formed at the closed back end of the tool collar; and, whereby the latch and catch mate in a preselected orientation.

6. The tool mount of claim 4 , wherein the alignment guide further comprises:
a partially closed latch at the front end of the sleeve;
a non-homogeneous portion of the tool collar outer annular wall proximate to the front end forming a catch; and, whereby the latch and catch mate in a preselected orientation.

7. The tool mount with flexible connector of claim 6 , further comprising a tool catch at the distal end of said tool.

8. The tool mount with flexible connector of claim 6 , wherein said sleeve has memory and is formed of at least one of plastics, resins, composites, rubbers, and polymers.

9. The tool mount with flexible connector of claim 1 , further comprising a tool with a shaped proximal end and an annular bearing guide reversibly mountable to said tool socket.

10. The tool mount with flexible connector of claim 9 , wherein the hinge moves from an at rest position to an active position when the distal end of the tool is inserted and returns to the at rest position when the finger is in the annular bearing guide.

11. 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.

12. The tool mount of claim 11 , further comprising a tool with a shaped proximal end and an annular guide reversibly mountable to said tool socket via the finger forming a reversible catch on the latch.

13. The tool mount of claim 11 , wherein said sleeve has memory and is formed of at least one of plastics, resins, composites, rubbers, and polymers.

14. The tool mount of claim 13 , wherein the hinge moves from an at rest position to an active position when the distal end of the tool is inserted and returns to the at rest position when the finger is in the bearing guide.

15. 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.

16. The method of claim 15 , further comprising further inserting the tool shaft until the finger moves into a guide in the tool's proximal end and reversible affixes the tool in the tool socket.

17. 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.

18. The method of claim 17 , further comprising further inserting the tool shaft until the finger moves into a guide in the tool's proximal end and reversible affixes the tool in the tool socket.
