Abstract

A latch and catch arrangement is disclosed, whereby a sleeve supporting a flexible hinge is oriented over a bearing in guide. An asymmetrical 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 bearing moves upward when a tool is inserted into a tool socket, and the flexible hinge, properly oriented by the alignment catch/latch, keeps the bearing 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 connector comprising:
a tool collar ( 201 ) with a closed back end ( 15 ) and an open front ( 12 ) and an outer annular wall and an open ended tool socket having an inner annular wall;
a bearing guide ( 14 ) with a fluid connection from the outer annular wall ( 11 ) to the inner annular wall ( 13 );
a bearing fitted within said bearing guide;
a generally cylindrical sleeve ( 30 ) with an outer annular wall ( 710 ) and inner annular wall ( 712 ) having an open end ( 708 ) and a partially closed end ( 709 );
said sleeve fitted over the tool collar;
a reduced thickness flexible hinge ( 37 ) formed in the sleeve, fluidly connecting the outer and inner annular walls; and,
a shaft ( 325 ) 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 ( 32 ) and “C” ( 35 ) shaped.

3. The tool mount with flexible connector of claim 1 , wherein the diameter of the bearing guide near the inner annular wall is of a smaller diameter of said bearing.

4. The tool mount with flexible connector of claim 1 , further comprising an alignment positioning catch ( 21 ) on the tool collar.

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

6. The tool mount of claim 5 , wherein the alignment positioning catch further comprises:
a partially closed latch ( 32 ) at the back end of the sleeve;
a positioning catch ( 21 ) formed at the dosed back end of the tool collar; and, whereby the latch and catch mate in a preselected orientation.

7. The tool mount of claim 5 , wherein the alignment guide further comprises:
a partially closed latch ( 720 ) at the front end of the sleeve;
a non-homogeneous portion ( 915 ) 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.

8. The tool mount with flexible connector of claim 7 , further comprising a tool catch ( 114 ) at the distal end ( 114 ) of said tool.

9. The tool mount with flexible connector of claim 7 , wherein said sleeve has memory and is formed of at least one of plastics, resins, metals, composites, rubbers, and polymers.

10. The tool mount with flexible connector of claim 1 , further comprising a tool ( 100 ) with a shaped proximal end ( 111 ) and an annular bearing guide ( 112 ) reversibly mountable to said tool socket.

11. A hand held device 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 bearing fitted within said bearing guide;
a shaft extending from said closed back end;
a positioning catch formed on at least one of the open front end and the back end of the tool collar; and,
a sleeve with an open front end and a partially closed back end having a latch which mates with said positioning catch over the tool collar with a flexible hinge formed therein.

12. The device of claim 11 , wherein an alignment further comprises:
a partially closed latch ( 32 ) at the back end ( 31 ) of the sleeve;
a positioning catch ( 21 ) formed at the closed back end of the tool collar; and, whereby the latch and catch mate in a preselected orientation.

13. The device of claim 11 , wherein an alignment guide further comprises:
a partially closed latch ( 720 ) at the front end of the sleeve; and,
a non-homogeneous portion ( 915 ) of the tool collar outer annular wall proximate to the front end forming a catch.

14. The device of claim 11 , wherein said flexible hinge is a reduced thickness ( 801 )
compared to the sleeve.

15. The device of claim 11 , further comprising:
a groove ( 930 ) formed in a tool collars annular wall ( 921 );
a rib ( 730 ) formed inside a sleeve inner annular wall ( 712 ); and, whereby the rib mates with the groove.

16. A method of reversibly attaching tools, the method comprising:
surrounding a tool collar having a tool socket therein with a cylindrical sleeve having and open front end, a partially open back end and a flexible hinge, fluidly connecting the outer and inner walls of the sleeve;
mating an orientation of the flexible hinge in the sleeve around the tool socket with a first asymmetrical alignment guide on the back end of the sleeve to a second guide on the back end of the tool collar whereby the hinge is positioned over a bearing; inserting a tool shaft with shaped proximal end and tool guide formed therein,
into the tool socket; and,
using force to move the bearing with the proximal end of the tool whereby the bearing moves away from the tool socket against the flexible hinge and causes the flexible hinge flap to become displaced and allow passage of the tool shaft.

17. The method of claim 16 , further comprising further inserting the tool shaft until the bearing moves into the tool socket and mates with the tool guide.

18. The method of claim 16 , further comprising keeping the position of the flexible hinge over the bearing in a preselected orientation via the first and second guides.

19. A method of reversibly attaching tools, the method comprising:
surrounding a tool collar having a tool socket therein with a cylindrical sleeve having and open front end a partially open back end and a flexible hinge, fluidly connecting an outer and inner walls of the sleeve;
mating an orientation of the flexible hinge in the sleeve around the tool socket with a first asymmetrical alignment guide on the front end of the sleeve to a second guide on the front end of the tool collar whereby the hinge is positioned over a bearing;
inserting a tool shaft with shaped proximal end and tool guide formed herein, into the tool socket; and,
using force to move the bearing with the proximal end of the tool whereby the bearing moves away from the tool socket against a flexible hinge and causes the flexible hinge flap to become displaced and allow passage of the tool shaft.

20. The method of claim 19 , the method further comprising further inserting a tool shaft until the bearing moves into the tool socket and mates with the tool guide.

21. The method of claim 19 , the method further comprising keeping the position of a flexible hinge over the bearing in a preselected orientation via the first and second guides.
