Definitions

  • This invention relates to a device for giving an alarm for failure to draw or pull out an engine key for a vehicle.
  • This embodiment is essentially constructed to form a series circuit by a door switch which is turned ON when the door is opened, a key switch which is turned ON when the engine key is inserted into the key cylinder, and an alarm unit, thus to supply a power to the series circuit by a drive power supply of a door-lock actuator which is activated in response to a door lock-operation.
  • the key cylinder lock may be also subjected to picking.
  • this invention contemplates providing a device for giving an alarm for failure to draw out a key for a vehicle which can completely prevent a driver from being away from a vehicle with the driver forgetting to draw out a key, wherein it is very difficult to reproduce a duplicate key of a key used in this device and it is also very difficult to conduct picking of a key cylinder lock when this device is employed, whereby it can be expected to prevent a vehicle from being stolen.
  • This invention further contemplates providing a device for giving an alarm for failure to draw out a key for a vehicle which can be easily installed and put into practice, and which has excellent durability.
  • a device for giving an alarm for failure to draw out a key for a vehicle characterized by the provision of a switch member provided in a key cylinder lock and turned ON when a magnet key as an engine key is inserted into the key cylinder lock by a power from a power supply provided in the vehicle, a door switch turned ON when the door is opened, and an alarm unit operative to produce an alarm when the door of the vehicle is opened under the state where the magnet key is inserted into the key cylinder lock as it is on the basis of the operating states of the switch member and the door switch.
  • FIGS. 1 to 14 show embodiments of this invention: More particularly, FIG. 1 is a model view showing an arrangement of an alarm device according to one embodiment of this invention, FIG. 2 is a block diagram showing an electrical connection of the alarm device of FIG. 1, FIGS. 3 to 6 are schematic explanatory views showing essential parts of this invention, respectively, FIGS. 7 and 8 are explanatory views showing switch members of this invention, respectively, and FIGS. 9 to 14 are explanatory views showing a different embodiment of this invention.
  • FIG. 1 is a schematic view showing, in a model form, an embodiment of this invention.
  • reference numeral 1 denotes a key cylinder lock constituting a part of an ignition coil or a key switch for a switch provided at a handle column of an automotive vehicle.
  • This key cylinder lock 1 is constituted, e.g., as shown in FIGS. 3 to 6.
  • reference numeral 2 denotes an outer tubular member having a predetermined length.
  • An outer hole 3 and an inner hole 4 communicating with each other and intersecting with each other are provided in the outer tubular member 2 from a suitable portion of the outer circumferential portion toward the radial direction.
  • two penetration holes each comprised of outer hole 3 and inner hole 4 are formed at a required interval.
  • Reference numeral 5 denotes an inner tubular member rotatably received over a predetermined angular range within the outer tubular member 2.
  • Grooves 6 of a suitable size are formed at portions corresponding to the above-mentioned penetration holes of the outer circumferential portion of the inner tubular member 5, respectively.
  • a key hole 8 corresponding to a key body 7a of a magnetic key 7 as an engine key shown in FIG. 3 is opened.
  • Reference numeral 9 denotes movable obstruction elements each accommodated within both the inner hole 4 of the outer tubular member 2 and the groove 6 of the inner tubular member 5.
  • a plurality of magnet pin tumblers 9a and 9b are used.
  • Each movable obstruction element is biased toward the groove 6 by a spring member 10 having a relatively weak spring force fitted into the inner hole 4 of the outer tubular member in a locked state or before the magnet key 7 is inserted.
  • This magnetic key 7 is comprised of a key body 7a inserted into the key hole and a holding portion 7b integrally formed with the key body 7a.
  • a plurality of magnets g1 and g2 are embedded at the upper side portion of the key body 7a with a predetermined spacing therebetween. The polarities of these plural magnets g1 and g2 may be arbitrarily combined.
  • Reference numeral 11 denotes a switch member which is provided in the key cylinder lock 1 of the key switch for an ignition switch, and which is opened and closed in dependency upon the insertion into the key hole 8 of the magnet key 7 and the detachment therefrom.
  • a magnetic responsive switch which detects that the movable obstruction element 9 jumps up against the spring force of the spring member 10 from the groove 6 of the inner tubular member by insertion of the magnet key 7 and becomes close to the switch, whereby the magnetic responsive switch is brought into a closed state.
  • the magnetic responsive switch 11 there may be used, e.g., a switch member 11A comprising a fixed contact piece 11a as a fixed contact and a movable contact piece 11b as a movable contact as shown in FIG. 7 or a magnetic responsive lead switch 11B as shown in FIG. 8.
  • switch members 11 using a magnetic responsive switch are suitably assembled into a plurality of outer holes 3 of the outer tubular member 2 as shown in FIGS. 3 to 6, respectively. Respective switch members 11 and 11 are connected in series and are protected by a cover member (not shown).
  • reference numeral 12 denotes a door switch which is turned ON when the door of a vehicle is opened.
  • An electrical load 13 is connected to this door switch 12.
  • Reference numeral 14 denotes an alarm unit such as a buzzer connected between the switch members 11 of the key cylinder lock 1 and the door switch 12. In this embodiment, this alarm unit 14 is energized using a battery 15 mounted in a vehicle as a power supply when both the switch member 11 and the door switch 12 are turned ON to produce an alarm. Additionally, reference numeral 16 denotes a room lamp connected to the battery 15 through the door switch 12 and a room lamp switch 17.
  • the structure of a key cylinder lock 1A mainly differs from that of the above-described embodiment of this invention.
  • this key cylinder lock 1A essentially comprises an outer tubular member 2a, an inner tubular member 5a rotatably provided within the outer tubular member 2a, and driver pins 26 adapted to thrust movable pins 25 provided in the outer tubular member 2a and provided in the inner tubular member 5a by spring members 10a in a radial direction of the key hole 8a for a magnet key 7A at all times.
  • driver pins 26 adapted to thrust movable pins 25 provided in the outer tubular member 2a and provided in the inner tubular member 5a by spring members 10a in a radial direction of the key hole 8a for a magnet key 7A at all times.
  • At suitable portions of thin thickness of the outer tubular member 2a there are formed a plurality of penetration holes 27 adapted so that a plurality of magnetic responsive switches 11c each serving as a switch member can be fitted.
  • the door switch when the door is opened, the door switch is turned ON.
  • the alarm unit produces an alarm, thereby making it possible to prevent failure to draw out a key.
  • the modified embodiment shown in FIGS. 13 and 14 mainly differs from the above-described embodiment in that a timer TM is newly provided.
  • a controller 30 including a timer TM for allowing the alarm unit to be operative for a fixed time.
