Abstract

In a hand video controller having two portions (11, 13) tiltable with respect to each other to make or break a series of spaced electrical switch contacts (26) to move a video cursor and having one-piece spring (47) having inner and outer connected rings (31, 33) to return the portions to a neutral position, an improved spring mounting comprising a mounting block (15) having a bearing recess (19) attached to one controller portion (11), a switch operator holding member (20) having a matching bearing surface extension (22) and attached to the other controller portion (13), switch contact means (27) between the block and holding member, and wherein the rings of the spring are connected respectively to and between the block and holding member and tilting movement of the controller portions deflect the spring rings and bring spaced flexible switch operators (28) extending from the holding member into contact with at least one of the switch contacts (26).

Claims

1. Means for mounting a spring for a switch mechanism contained in a two-part container, said spring having connected outer and inner rings, said rings being adaptable to be flexed with respect to each other, comprising,

(a) a first mounting means mounted on one part of the container and having a curved bearing recess on one surface;

(b) means to mount one of said spring rings to said means;

(c) a switch operator holding member including an extension having a curved bearing surface in bearing contact with said mounting means recess and adapted for universal movement with respect to said recess;

(d) means to mount the other of said spring rings to said holding member whereby said spring is situated between said block and said holding member;

(e) electrical switch contact means extending between said block and said holding member;

(f) means to attach said holding member to the other part of the container, whereby said spring allows universal tilting motion between the two parts of said container; and

(g) switch operators mounted in and extending from said holding member and spaced from said switch contact means in a non-tilting position of said container parts, at least one of said switch operators being movable into and out of contact with said switch contact means to make and break electrical contact when said parts are tilted with respect to each other.

2. The invention set forth in claim 1 wherein said electrical switch contact means includes means forming a central aperture in said extension and means extending from the interior of said extension through said recess to threadedly attach said holding member to said first mounting means while allowing relative movement therebetween.

3. The invention set forth in claim 1 wherein said switch operators and said means to attach extend through multiple apertures in said holding member radially inboard of said inner ring.

4. The invention set forth in claim 1 wherein said switch operators are flexible insulative inserts insertible in apertures in said holding member and extending outwardly and positioned above a series of electrical contact points in said switch contact means.

5. The invention set forth in claim 4 in which said inserts include a truncated conical end extending outwardly and above said contact points.

6. The invention set forth in claim 1 in which said holding member has a radial dimension substantially equal to the outside diameter of said inner ring.

7. The invention set forth in claim 1 in which said mounting means recess is contained in a circular boss extending from a surface of said mounting means, said boss having a diameter less than the diameter of said outer ring.

8. In a hand-operated video controller having a lower base portion and an upper portion wherein the portions are tilted relative to each other from a neutral position to make or break a series of spaced electrical contacts and spring means to return said portions to such normal neutral position, the improvement which comprises:

(a) means to mount a part of said spring to one of said controller portions;

(b) a switch operator holding member mounted to the other of said controller portions and being attached to a second part of said spring;

(c) electrical switch contact means extending between said holding member and a facing surface of said means to mount,

(d) said spring means being deposed between said holding member and said switch contact means; and

(e) switch operators extending from said holding member to a position spaced from said switch contact means in said neutral position, at least one of said switch operators being moveable into and out of contact with said switch contact means when said base portion and upper portion are tilted with respect to one another; and

(f) universal joint means extending between said holding members and one of said controller portions permitting tilting of said controller portions with respect to each other.

9. The invention set forth in claim 8 in which said means to mount includes a mounting block fixedly mounted in said upper controller portion.

10. The invention set forth in claim 9 in which said mounting block includes a curved bearing recess, said holding member containing a matching curved bearing surface, said bearing recess and said curved bearing surface forming said universal joint means.

11. The invention set forth in claim 8 in which said switch operators are flexible insulative inserts insertible in apertures in said holding member and extending outwardly and positioned above a series of electrical contact points in said switch contact means.

12. The invention set forth in claim 11 in which said inserts include a truncated conical end extending outwardly and above said contact points.

13. The invention set forth in claim 8 in which said holding member is generally radially contiguous to said second part of said spring.

14. The invention set forth in claim 8 in which said spring means comprises connected inner and outer rings and said holding member is connected to the inner ring and is contiguous to the outside diameter of said inner ring.
