Definitions

  • This invention relates in general to selective call receivers such as pagers, and more specifically to a housing for a battery powered pager that folds to protect external components while not in use and whose thickness when folded is approximately the same as the thickness of the battery.
  • Selective call radio receivers such as pagers are used to alert a user of a message.
  • Such devices generally incorporate a radio receiver capable of producing either an audible alerting signal which may be heard by the user or a vibrating sensation which may be felt by the user.
  • Some pagers provide the additional features of a voice message following the audible alert or a message visually displayed on a screen.
  • Pagers typically are manufactured in many different shapes to fulfill different user requirements. For example, pagers are manufactured in the shape of a cigarette pack for attachment to a belt, in the shape of a pen for attachment to a shirt pocket, or in the shape of a credit card for insertion into a shirt pocket or billfold. Each of these different shaped pagers typically require substantially the same components, i. e., speaker, battery, antenna, switches, display screen, printed circuit board for the electronic circuit elements.
  • the pager be small in physical dimensions so as not to be cumbersome to the user. Pen shaped and credit card shaped pagers were designed for this very reason. Even so, reduced dimensions continues to be a major factor in pager designs. However, the size of the components mentioned above have placed restrictions on pager dimensions. For example, although improved technology has reduced battery size in recent years, battery size continues to be relative large. Thus, what is needed is a housing for a battery powered pager that folds while not in use to protect external components and whose thickness when folded is substantially the same as the thickness of the battery.
  • Another object of the present invention is to provide a selective call receiver that folds while not in use to protect external components and whose thickness when folded is approximately the same as the thickness of the battery.
  • a housing for a battery powered pager that folds while not in use to protect external components such as controls and a display device and has a thickness when folded approximately the same as the thickness of a battery.
  • the housing encompasses electronic circuitry for coupling to the battery for receiving a message and alerting the user of the message, and comprises a first member having a first cavity.
  • a second member has a second cavity and is rotatably coupled to the first member and is capable of being placed in first and second positions relative to the first member, wherein the first position is one wherein the first and second cavities cooperate to accommodate the battery.
  • FIG. 1 is block diagram of a prior art pager.
  • FIG. 2 is a top view of the preferred embodiment of the present invention in an open position.
  • FIG. 3 is a cross sectional side view taken along the dotted line 2-2 of FIG. l.
  • FIG. 4 is a cross sectional side view taken along the dotted line 2-2 of FIG. 1 when the pager is folded into a closed position.
  • a block diagram of a typical pager comprises a pager circuitry 1 coupled to each of an antenna 2, a battery 3, an alert apparatus 4, and a control apparatus 5 such as on/off, volume control, and display control switches for performing the pager operation well known to those skilled in the art.
  • a display apparatus 6 may be included in the pager for visually displaying an alert or a message.
  • the thin articulated pager in accordance with the preferred embodiment comprises a housing 11 including two members 12 and 13.
  • the member 12 includes a plate 14 and encloses a cavity 15 for the pager circuitry 1, antenna 2, and alert apparatus 4.
  • the control buttons 16 protrude through the slots 17 in the plate 14.
  • the member 13 includes a plate 18 and encloses a cavity 19 for the pager circuitry 1, antenna 2, and alert apparatus 4.
  • the member 18 further includes a cavity 21 for receiving a jacket 22 of member 14 when the members 14 and 18 are folded together as shown in FIG. 3.
  • the member 12 includes a slot 25 for receiving a latching mechanism 26 of the member 13 in the folded position.
  • a battery door 27 is provided for inserting and removing the battery 28, which is located in the cavity 30.
  • the members 12 and 13 and the battery door are rotatably coupled by hinges 29.
  • the battery shown in the drawings is a AA type battery. However, the invention could be implemented using any known type of battery, including a "button" or "disc” battery.
  • the pager normally would be stored in the folded position shown in
  • FIG. 3 This folded position protects the display screen 23 from accidental damage, such as being scratched. Also, the control buttons 16 are protected from inadvertent activation. Upon an alert signal being received, the pager user would open (unfold) the pager similar to the position shown in FIGs. 1 and 2. The display screen 23 and control buttons 16 are then readily available for viewing and activation, respectively.
  • the alert could be accomplished in any of several ways well known in the industry.
  • a silent alert may be provided by a vibrating motor (not shown) attached within the housing 11 or by a tone emitted from the pager.
  • the item having the largest dimension that restricts the minimizing of the thickness of the pager is the battery 28.

Abstract

Le logement d'un dispositif de recherche de personnes alimenté par des piles se replie lorsque le dispositif n'est pas utilisé afin de protéger des composants extérieurs tel que des commandes et un dispositif d'affichage. Lorsque le dispositif est replié, son épaisseur est à peu près identique à l'épaisseur des piles. Le logement contient des circuits électroniques de réception de messages et d'avertissement de l'utilisateur lors de la réception des messages, et comprend un premier organe avec une cavité interne. Un deuxième organe avec une deuxième cavité, rotativement couplé au premier organe, peut être placé en une première position et en une deuxième position par rapport au premier organe. Dans la première position, les première et deuxième cavités coopèrent afin de loger les piles.
