Abstract

A selective call receiver includes first and second housing portions forming a chamber therebetween which houses the electronic circuitry for receiving messages, a display for displaying the messages, and an annunciator for alerting a user that a message has been received. The first housing portion has an opening therein through which keys of an elastomeric keypad are accessible to the user. The keypad also includes a base portion for forming a seal between the first and second housing portions and a rim which extends into an additional opening in the first housing portion proximate the periphery thereof for sealingly receiving a lens therein.

Claims

1. A selective call receiver of the type which includes a housing having a chamber therein for containing electronic circuitry which receives messages and alerts a user that a message has been received, and further including user control elements accessible by a user from the exterior of said housing, comprising:

a first housing portion;

a second housing portion for cooperating with said first housing portion to form said chamber;

an elastomeric keypad for controlling said electronic circuitry and for forming a seal between said first and second housing portions, said housing portion having at least one opening therein, said elastomeric keypad comprising a base portion pressed between said first and second housing portions to form said seal, and at least one control key, said key being received through said at least one opening; and

display means coupled to said electronic circuitry, comprising;

an additional opening in said first housing portion positioned over said display means;

a lens; and

first means coupled to said base portion and extending into said additional opening for sealingly receiving said lens.

2. A selective call receiver according to claim 1 wherein said first means comprises a rim integrally formed with said base portion and extending into said additional opening proximate the periphery of said additional opening for retainably receiving said lens and forming a seal between said lens and said first housing portion.

3. A selective call receiver according to claim 2 wherein said rim includes a retaining lip and a retaining ledge for frictionally receiving said lens therebetween.

4. A selective call receiver according to claim 1 further comprising shock absorbing means positioned within said second housing portion, the combination of said display means and said electronic circuitry being cushioningly retained between said elastomeric keypad and said shock absorbing means.

5. A selective call receiver according to claim 4 wherein said shock absorbing means is an elastomeric pad.

6. A selective call receiver of the type which includes a housing having a chamber therein for containing electronic circuitry which receives messages, display means coupled to the electronic circuitry for displaying the messages, and annunciator means for alerting a user that a message has been received, comprising:

a first housing portion having at least first and second openings therein;

a second housing portion for cooperating with said first housing portion to form said chamber;

an elastomeric keypad including a base portion for forming a seal between said first and second housing portions, at least one control key accessible through said first opening, and a rim extending into said second opening proximate the periphery thereof; and

a lens for viewing said display means therethrough, said lens being sealingly received within said rim.

7. A selective call receiver according to claim 6 wherein said base portion is pressed between said first and second housing portions to form said seal.

8. A selective call receiver according to claim 6 wherein said rim includes a retaining lip and a retaining ledge for frictionally receiving said lens therebetween.

9. A selective call receiver according to claim 6 further comprising shock absorbing means positioned within said second housing portion, the combination of said electronic circuitry and said display means being cushioningly retained between said elastomeric keypad and said shock absorbing means.
