Definitions

  • This invention relates to a portable telephone housing. More particularly, it relates to a portable telephone housing with a sliding member which encases an antenna and extends from the housing to expose a luminescent keypad.
  • Portable telephones are well known in the art. Some portable telephones are used in a home, communicatingwith a base station which is connected to a telephone line; some portable telephones are more mobile in nature, for instance car phones, these phones utilize cellular technology. Regardless of the type of portable telephone, certain problems are common to all of these telephones.
  • the keypad on a telephone is likely to encounter debris or be physically damaged. This may result in degraded performance of the telephone.
  • Another problem with such telephones relates to the difficulty of reading the keypad when the telephone is in a dark environment. While a lighted keypad can readily be provided, such a keypad consumes excessive energy. Since the energy source on a portable telephone is limited, it is desirable to conserve the energy source.
  • a final problem relates to the antenna of portable telephones.
  • the antenna must be pulled out and pushed into the telephone.
  • separate motion is required to utilize the antenna.
  • This pushing and pulling of the antenna often damages the antenna.
  • the antenna is in its extended position it is vulnerable to physical damage.
  • the antenna is extended itmay injure individuals near the telephone, for instance by poking them in the eye.
  • the sliding member moves along the track away from the body, exposing a keypad.
  • the keypad includes a light sensor which is coupled to a control element which variably illuminates the keypad contingent upon the ambient light.
  • the sliding member encases an antenna which works in conjunction with an antenna within the body of the portable telephone.
  • FIGURE 1 is a perspective view of the housing, or body, of a portable telephone, in accordance with the present invention, including a sliding member which is in a contracted, or closed, position.
  • FIGURE 2 is a perspective view of the housing of a portable telephone, in accordance with the present invention, including a sliding member which is in an extended, or open, position.
  • Figure 3 is a cross-sectional exploded view, taken along the line 3-3 of Figure 2, of a track formed in the body of a portable telephone and the engaging member formed within the sliding member which interconnects to the track, in accordance with the present invention.
  • FIGURE 4 is a cross-section view of the energy conserving illuminated keypad in accordance with the present invention.
  • FIGURE 5 is a cross-sectional view of the antenna within the body and the antenna within the extended sliding member of the portable telephone of the present invention.
  • FIGURE 6 is a cross-sectional view of the antenna within the body and the antenna within the contracted sliding member of the portable telephone of the present invention.
  • the portable telephone 8 includes a body (or housing) 10.
  • the housing is formed of a dielectric material.
  • a display 12 utilized to display a phone number or other information, as is known in the art.
  • the body 10 also includes an earpiece 14.
  • the body 10 includes a sliding member (or slide) 16, also preferably formed of a dielectric material, in a closed position.
  • the sliding member 16 includes a top region 16A and a bottom region 16B.
  • a microphone 18 is positioned in the bottom region 16B.
  • Figure 2 depicts the sliding member 16 in an open position, extending from the body 10. It can be appreciated that in a preferable embodiment bottom region 16B is curved so as to be closer to the mouth of an individual using the telephone 8. When the telephone 8 is in this open position, it can be seen that the body 10 includes a keypad (or keyboard) 30. Thus, in an open position the keypad may be utilized, while in the closed position it is shielded from physical damage, such as intrusion by debris or liquid.
  • a keypad or keyboard
  • the track 32 includes an elongated protrusion 40 which runs along the longitudinal axis of the body 10. Adjacent to the elongated protrusion 40 is an elongated slot 42 which is formed within the body 10 and also runs along the longitudinal axis.
  • Sliding member 16 includes engaging member 34 which is cooperatively aligned with track 32.
  • An elongated aperture 44 runs along the longitudinal axis of the sliding member 16.
  • an elongated lip 46 runs alongthe longitudinal axis.
  • engaging member 34 allows sliding member 16 to move along the track 32 of body 10 from a contracted position, as shown in Figure 1 to an extended position as shown in Figure 2.
  • this movement activates the telephone.
  • One way of accomplishing this activation is to place a resistance element 47 within the slide 16.
  • the resistance element 47 may be the microphone 18.
  • the resistance element 47 may be coupled to a lead 48 which makes contact with a current source 49 when the slide 16 is in an extended position.
  • a current sensor 50 may be used to sense current in resistance element 47. Once the current sensor 50 is triggered, the phone may be activated, as is known in the art. Thus, by moving the slide from its contracted position to its extended position, the telephone is activated.
  • the keypad is formed of an elastomeric rubber which conducts light.
  • a printed circuit board 51 Positioned beneath the keypad 30 is a printed circuit board 51, preferably formed of a translucent material.
  • a luminescent panel 53 Positioned beneath the board 51 is a luminescent panel 53.
  • the panel 53 is activated in the following manner.
  • a light sensitive diode 54 is positioned on the printed circuit board 51, beneath the translucent elastomeric keypad 30.
  • the output from the diode 54 is fed by lead 56 to a control element 58.
  • the control element 58 may be a microprocessor or other element known in the art.
  • the control element 58 via lead 59, variably illuminates the panel 53.
  • the control element is configured such that when the sensor 54 generates a weak signal the panel 53 is highly illuminated. Similarly, when the sensor 52 generates a strong signal the panel 53 is not illuminated.
  • the keypad 30 is illuminated when the ambient light is low and lighting is necessary. On the other hand, when the ambient light is adequate, the keypad 30 need not be illuminated, thereby conserving energy.
  • Figure 5 Another aspect of the present invention is revealed in Figure 5. It is difficult to provide a suitable ground plane for the antenna of a small package, such as a portable telephone. As a result, antennas in portable telephones are usually pulled from within the body to a position which extends from the body.
  • FIG. 5 a portable telephone body 10 is depicted in cross section while the slide 16 is in an extended position.
  • a stripline antenna 70 is positioned within the slide 16.
  • the antenna 70 in conjunction with the shielding of the case, modeled as line segment 72, forms a dipole antenna, with the stripline 70 being a quarter wavelength of the frequency for which the portable telephone is utilized.
  • the stripline 70 is used as the radiating element, being fed from transmitter 74.
  • the width of the stripline 70 is determined by creating an impedance match to the shielding.
  • FIG 6 the configuration of the shielding of the case 72 and the antenna 70 is depicted when slide 16 is in a contracted position.
  • the shielding isolates the antenna, thus it is difficult for the antenna to receive signals.
  • the length of the case is more than one quarter of a wavelength. If the body is formed of a material with a dielectric constant of approximately 2, the dielectric loading of the body results in a body with effectively a half wavelength.
  • the antenna 72 is treated as a transformer. The transmitter 72 is fed at the base of the resultant J antenna. The exact location of the feed is selected in order to match the antenna to the shielding impedance, which is approximately 50 ohms.
