  • Japanese Kokai Patent Application No. 2004-189431 describes a flexible piezoelectric sensor that is set in a vertical direction for contacting foreign objects on a sliding door. When an object contacts a sliding door, the piezoelectric sensor is deformed and provides an output signal.
  • One drawback associated with such an arrangement is that it is necessary to set the piezoelectric sensor over the entire region of detection of such an object. This does not provide an economical solution.
  • a drawback associated with the rocking panel is that when a foreign object presses on it in a door opening direction, friction develops between the foreign object and the rocking panel. The load on the foreign object may increase, which is undesirable.

  • the irradiating light of such a photoelectric switch is blocked, the presence of a foreign object near the inlet of the doors is detected. Control can then be performed to stop the door-opening operation to prevent trapping an object in the door slot.
  • Japanese Kokai Patent Application No. 2002-265175 discloses a light projector and a light receiver that are set facing each other on the lower portion of the vertical and upper members of the doorframe. Foreign objects that approach the inlet of the door slot are detected.

  • Japanese Kokai Patent Application No. HPI ll[1999]-310375 a light projector and a light receiver are set on the upper and lower sides of the door slot to detect foreign objects invading the slot.
  • the irradiating light of the photoelectric switch passes through the space where the passengers are present in the door opening. Therefore, faulty operation may take place because of external disturbances such as sunlight or light from a light source other than the light projector. Additionally, dust and debris can interfere with the operating efficiency. In particular, when visible light is used as the irradiating light for the photoelectric switch, the irradiating light may enter the eyes of passengers, which is typically undesirable.

  • a radiation detector 46 detects when the radiation beam 44 is incident onto the detector 46.
  • the body 32 is flexible enough to at least partially deflect when contacted by an object such as a human finger. Deflection of the body 32 will interrupt the radiation beam 44 so that it is not being detected by the detector 46. Under these circumstances, the sensor 40 provides an indication to the controller 60 regarding the detection of an object at the corresponding interface 28. The controller 60 can then respond according to the needs of a particular situation.
  • the type of radiation used comprises light.
  • the source of radiation 42 comprises a light source such as a laser or a light emitting diode.
  • the detector 46 comprises a photo detector in one example.
  • a flexible tube such as that shown in the example of Figure 4 provides resiliency at the interface 28 so that any impact between the door panel 24, the adjacent surface of a door frame member 22, or both and the object will be cushioned because of the presence of the flexible member 26. Any impact on the object will be mitigated by the give of the flexible member 26.
  • the flexibility of the flexible member 26 also makes it easier under most circumstances to remove an object that becomes caught in the spacing at the interface 28.
  • Another advantage associated with a flexible tube such as that shown in Figure 4 is that it effectively houses the radiation beam 44.
  • light is used as the type of radiation for the sensor 40.
  • a flexible tube in such an example provides a shield for the light to avoid interference from outside light sources.
  • the flexible tube can also provide a shield to protect a light source or light detector such as a photo detector from becoming dirty because of dust or other contamination.
  • the detector 46 is housed within a housing portion 50A near one end of the door panel 24 and the radiation source 42 is housed within a housing portion 50B near an opposite end of the door panel 24.
  • the body 32 of the flexible tube may extend right up to or very close to the edges of the housing portions 50A and 5OB to provide maximum protection of the sensor components and maximum avoidance of interference by outside radiation (e.g., light) sources.
  • Figure 5 schematically illustrates another example arrangement. In this example, only one housing 50 houses both of the radiation source 42 and the detector 46. A reflector 52 is provided at an opposite end of the assembly.
  • the detector 46 detects a reflected beam 54 that is a result of the beam 44 emanating from the source 42 and reflecting off the reflector 52. In this example, any deflection of the tube body 32 into the path of either beam 44 or 54 will interrupt the ability for the detector 46 to detect the reflected beam 54. This provides an indication to the controller 60 regarding the detection of an object at the interface 28.
  • One advantage to the arrangement of Figure 5 is that the position of the source 42 and the detector 46 are both conveniently placed securely above the door so that they are out of the way from being potentially contacted by an individual or an object passing through the doorway. They are also less susceptible to dust or other contaminants especially when appropriately protected by the housing 50. Additionally, providing signal communication between the detector 46 and the controller 60 may be more convenient in an arrangement such as that illustrated in Figure 5.

  • a connector plate 68 and the frame member 62 each include an opening for receiving a fastener 70 that secures the mounting plate 66 and, therefore, the flexible tube body 32 in a desired position.
  • the illustrated example also includes a protective covering 72 that may provide a decorative exterior over the components shown in Figure 6. When a cover 72 is used, it preferably has sufficient flexibility to avoid interfering with deflection of the flexible member 26 responsive to contact with an object approaching the interface 28.
  • Another advantage to a flexible tube embodiment is that it provides the ability to reduce the gap or spacing at the interface 28.
  • the gap size G exists between the example door panel 24 and the door frame member 22.
  • a smaller gap size F exists at the interface 28 at the location where an object may potentially enter the spacing between the door panel 24 and the door frame member 22. Reducing the size of the gap provides additional protection against objects potentially becoming caught within the interface 28.
  • Figure 7 is a cross-sectional illustration similar to Figure 6 showing selected portions of another example embodiment.
  • the tube body 32 includes a protrusion 80 for further reducing the size of the gap F at the interface 28 between the flexible member 26 and, in this example, the door panel 24.
  • the example of Figure 7 also includes a blocker portion 82 supported on a rib 84 within the channel 34.
  • the rib 84 effectively divides the channel 34 into a first portion 34A and a second portion 34B.
  • the second portion 34B is closer to the interface 28.
  • the radiation beams 44 and 54 pass through the first portion 34A of the channel in this example.
  • the rib 84 includes a relatively easily deformed curved portion 86 and an inclined portion 88. As can be appreciated from the illustration, the inclined portion 88 orients the curved portion 86 toward the first portion 34A of the channel.

  • Figure 8 shows the example of Figure 7 in another condition where an object contacts the tube body 32 near the interface 28.
  • a contact force which is schematically shown at C, impacts the tube body 32 near the second portion 34B of the channel.
  • the relatively easy bendable portion 86 of the rib 84 and the inclination of the portion 88 tend to facilitate deformation of the tube body 32 in a direction away from the door panel 24.
  • the blocker portion 82 moves into a position where it blocks at least one of the radiation beams 44 or 54. This results in an indication that an object is detected near the interface 28.
  • Figures 7 and 8 is that it provides a larger tolerance for adjusting the axis of the radiation beam 44.
  • this example arrangement provides the ability to detect when an object is approaching the interface 28 in a manner such that the object may become caught within the spacing between the door panel 24 and the door frame member 22.
  • Figure 9 shows another condition of the example of Figure 7.
  • an object contacting the tube body 32 provides an impact force as schematically shown at D.
  • the inclination of the portion 88 of the rib 84 prevents deformation of the portion of the body 32 that establishes the second portion 34B of the channel. Instead, only the portion of the body 32 associated with the first channel portion 34A is deflected.
