Definitions

  • This invention relates to an automatic umbrella, more particularly to an automatic umbrella with a closing signaling device.
  • a conventional automatic umbrella capable of automatic opening and closing disclosed in Taiwanese Utility Model Publication No. 354874 is shown to include a frame 1, an opening spring 2 mounted in a central shaft 101 of the frame 1, a handgrip 3 mounted on a lower end of the central shaft 101, a control unit 4 mounted in the handgrip 3, and a transmitting mechanism 5 coupling the handgrip 3 to the frame 1.
  • the frame 1 includes the central shaft 101, which has a plurality of telescopic shaft sections, a top hub 102 secured on an uppermost end of the central shaft 101, a runner 103 slidably mounted on the central shaft 101, and a plurality of ribs 104 pivotally mounted between the top hub 102 and the runner 103.
  • the control unit 4 has a biased lever 401 pivotally mounted on the handgrip 3, and a button 402 operable to move the lever 401 such that, when the central shaft 101 is telescopically folded, the lever 401 is brought to engage an upper shaft section 101' , and such that, when the button 402 is pressed, the lever 401 is disengaged from the upper shaft section 101' so that the shaft sections of the central shaft 101 are extended upwardly by means of the opening spring 2, and the runner 103 is then moved toward the top hub 102 by means of the transmitting mechanism 5 so as to spread the ribs 104 for opening the umbrella.
  • the button 402 When it is desired to close the umbrella, the button 402 is pressed, and a lower end of the lever 401 is brought to move a biased plate 403 so as to release a retaining member 501 of the transmitting mechanism 5 from the biased plate 403 to thereby permit downward movement of the runner 103 for collapsing the ribs 104. Subsequently, the central shaft 101 can be pushed down and folded until the upper shaft section 101' reaches the lever 401 and is retained thereby.
  • the user when pushing down the central shaft 101 for telescopically folding the same, the user needs to apply a relatively large force to the central shaft 101 to overcome a biasing action of the opening spring 2. If the user inadvertently lets the umbrella slip from his/her grasp during pushing, the central shaft 101 may extend and the ribs 104 may spread instantly, which may result in damage to the umbrella and injury to the user and people nearby.
  • An object of the present invention is to provide an automatic umbrella which has a closing signaling device to indicate a user that the umbrella has been placed in a closed state.
  • the automatic umbrella includes a central shaft, a handle securely mounted on a lower end of the central shaft, a runner which is slidably sleeved on the central shaft and which is movable between proximate and distal positions that correspond respectively to closed and opened states of the umbrella, an opening spring disposed to bias the runner to move to the distal position, and a retaining unit disposed to releasably retain the runner relative to the handle against a biasing action of the opening spring when the runner is in the proximate position.
  • the automatic umbrella further includes a signaling device which includes a sensor unit and an alert unit.
  • the sensor unit has a first sensor which is mounted on one of the handle and the lower end of the central shaft, and a second sensor which is configured to activate the sensor unit to emit a signal once a predetermined spatial relationship is established between the first and second sensors as a result of movement of the second sensor toward the first sensor, and which is mounted to be movable with the runner such that, once the runner is moved to reach the proximate position, the sensor unit emits the signal.
  • the alert unit is mounted on the handle to receive the signal and generate an alert indication.
  • the preferred embodiment of an automatic umbrella is shown to comprise a central shaft 200 extending along an axis, a handle 400 securely mounted on a lower end 2301 of the central shaft 200, a runner 300 slidably mounted on the central shaft 200 and movable between proximate and distal positions that respectively correspond to closed and opened states of the umbrella, an opening spring 500 disposed to bias the runner 300 to move to the distal position, and a retaining unit.
  • the central shaft 200 is composed of upper tube 210, a middle tubular segment 220, and a lower tube 230 telescopically fitted to one another.
  • the upper tube 210 has an upper end 2101 and an upper middle segment 2102 telescopically fitted to the middle tubular segment 220.
  • the lower tube 230 has the lower end 2301 that has the handle 400 mounted thereon.
  • the retaining unit includes a retained hole 240 formed in the upper middle segment 2102 of the upper tube 210, and a retainer 410 which is disposed on the handle 400 and which is releasably retained in the retained hole 240 so as to secure the upper tube 210 to the handle 400 against the biasing action of the opening spring 500 when the runner 300 is in the proximate position and when the central shaft 200 is in a telescopically folded state.
  • the umbrella according to this invention further comprises a signaling device 100 that includes a sensor unit 10 and an alert unit 20.
  • the sensor unit 10 has a first sensor 11 mounted on the handle 400, and a second sensor 12 mounted on the runner 300 to be moved with the runner 300.
  • the sensor unit 10 may be a contact-type switch, a photosensitive switch, an electromagnetic sensing switch, a micro-switch, etc.
  • the first sensor 11 may be mounted on the lower end 2301 of the lower tube 230.
  • the second sensor 12 is configured to activate the sensor unit 10 to emit a signal once a predetermined spatial relationship is established between the first and second sensors 11,12 as a result of movement of the second sensor 12 toward the first sensor 11.
  • the predetermined spatial relationship is established when there is a physical contact between the first and second sensors 11, 12 in the case that the sensor unit 10 is a contact-type switch or a micro-switch.
  • the predetermined spatial relationship may be established when there is a predetermined distance between the first and second sensors 11,12 in the case that the sensor unit 10 is a light-inducting switch or an electromagnetic sensing switch.
  • the alert unit 20 is mounted on the handle 400 to receive the signal and generate an alert indication.
  • the alert indication may be light or sound.
  • the runner 300 When it is desired to close and telescopically fold the umbrella, the runner 300 is pulled down toward the handle 400 to the proximate position.
  • the middle tubular segment 220 is retracted into the upper tube 210
  • the lower tube 230 is retracted into the middle tubular segment 220
  • the retainer 410 is engaged with the retained hole 240.
  • the predetermined spatial relationship between the first and second sensors 11, 12 is established such that a signal is emitted and is received by the alert unit 20, which generates an alert indication for indicating to the user that the umbrella is in a closed and folded state.
  • the second sensor 12 may be mounted on the upper middle segment 210 of the central shaft 200.
  • the umbrella according to this invention may include a central shaft 200 which is unfoldable, i.e., the central shaft 200 is in the form of a single-piece shaft.
  • the first sensor 11 of the sensor unit 10 of the signaling device 100 may be mounted on one of the handle 400 and a lower end of the central shaft 200, and the second sensor 12 may be mounted on the runner 300.
