Abstract

A vibrator bracket 224 for mounting a vibrator 226 including a motor 228, a shaft 231 controlled by the motor and weight 232. The bracket has members (260, 261) to engage the motor. The bracket has a shaft support, including an opening 275 for receipt of an end of the shaft remote form the motor whereby the shaft is positioned in the opening and deflection of the shaft is limited by the support.

Claims

1. A vibrator bracket for mounting a vibrator including a motor and weight carried on a shaft, the shaft having a diameter and being driven by the motor, the bracket comprising:

a plate;

first and second members extending from the plate to hold the motor;

and a shaft support extending from the plate and including an opening larger than the diameter of the shaft for receiving an end of the shaft remote from the motor to allow radial movement of the shaft within the opening and to limit radial deflection of the shaft to a distance across a gap between an outer surface of the shaft and an edge of the opening.

2. The vibrator bracket as defined in claim 1, wherein the opening has a diameter which is larger than the diameter of the shaft.

3. The vibrator bracket as defined in claim 2, wherein the shaft support includes a third member extending from the plate generally parallel to the shaft.

4. The vibrator bracket as defined in claim 3, further including a fourth member extending orthogonal from the third member, the forth member including the opening.

5. In combination:

a vibrator including a motor, a shaft driven by the motor and a weight carried on the shaft; and

a bracket including

a plate,

at least one member extending from the plate to hold the motor,

and a shaft support extending from the plate and including an opening for receiving an end of the shaft remote from the motor, a diameter of the shaft being smaller than the opening to provide a gap between the shaft and the shaft support, wherein the shaft is positioned in the opening to permit rotation and some flexing of the shaft without a surface of the shaft contacting another surface and to limit deflection of the shaft to the gap within the opening to protect against severe deflection of the shaft.

6. The combination as defined in claim 5, wherein the opening has a diameter which is larger than a diameter of the shaft.

7. The combination as defined in claim 6, wherein the shaft support includes a third member extending from the plate generally parallel to the shaft.

8. The combination as defined in claim 6, wherein the opening is in a fourth member extending orthogonally from the third member.

9. A radio telephone comprising:

a circuit board supporting electrical components of the radio telephone;

a vibrator including a motor, a counter weight, and a shaft coupled to the motor and carrying the counter weight thereon; and

a bracket including

at least one member extending from the plate to engage the motor,

and a shaft support extending from the plate and including an opening, an end of the shaft remote from the motor positioned in the opening and spaced from the support to permit rotation of the shaft without contacting the support and allowing some radial deflection of the shaft, the shaft not contacting an edge of the support unless the radiotelephone experiences a severe force transverse to a longitudinal axis of the shaft whereby the support limits radial deflection of the shaft.

10. The radio telephone as defined in claim 9, wherein the opening has a diameter which is larger than a diameter of the shaft.

11. The radio telephone as defined in claim 10, wherein the shaft support includes a third member extending from the plate generally parallel to the shaft.

12. The radio telephone as defined in claim 11, further including a fourth member extending orthogonally from the third member, the opening in the fourth member.

13. The radio telephone as defined in claim 12, wherein the bracket includes support elements extending from the plate for mounting the bracket on the printed circuit board.
