Definitions

  • the present invention relates to an inflatable structure, more particularly but not exclusively, the present invention relates to an automatically regulated inflatable structure and methods for its regulation.
  • Inflatable structures are well known in the art. Inflatable tents, domes and other structures of various sizes and shapes have been available on the market for decades.
  • U.S. Pat. No. 6061969 to Leary discloses a dome-shaped inflatable structure which is used as a greenhouse.
  • This structure has a double-walled structure of plastic sheet material which gives the greenhouse structural rigidity when inflated and which increases the thermal protection provided by the greenhouse.
  • the inflatable greenhouse has also a lower ring which is separately inflatable with a dense medium, such as water, for stabilizing and anchoring the greenhouse against movement by wind or storms.
  • U.S. Pat. No.5987822 to Calabro et.al. discloses an inflatable tent having a frame and a removable cover.
  • the frame consists of a single inflatable continuous generally- tubular member, which comprises a base section and an upright section and the base section is fixedly attached at one or more connection points to the upright section.
  • Some devices use regulated air pressure in order to keep the inflatable structure as stable as possible.
  • French Patent No. 2648192 to Flament et-al. discloses a blower which includes a fan unit the rotational speed of which can be varied by virtue of an electronic device for varying the frequency of its supply current, the device being controlled by a logic control unit in response to the signals emitted by sensors for monitoring the speed of the external wind and the pressure in the structure.
  • the invention discloses a system for inflating an inflatable structure which may comprise; an inflatable structure of various shapes and sizes; a blower connected to the inflatable structure and adapted to inflate at least a portion of the inflatable structure; a control unit adapted to operate said blower; at least one sensor attached to inflatable structure an adapted to gather information and to transmit the information gathered to the control unit; a processor for processing the information gathered by the sensor via an algorithm to trigger the activation of the blower.
  • the sensors which are used to indicate a deflation in the inflatable structure may well be accelometers which monitors movement, changes in movement or in its direction. Few sensors can be employed at different location of the inflatable structure, the readings between sensors may be compared to increase reliability of the algorithm which processes the readings and determines the schedule to activate the blower.
  • the algorithm may also take into consideration a timetable inserted by a user via an interface on the inflatable structure, on the blower or via a smart phone application. Integral sensors of the smart phone itself can be used as a sensors to monitor the inflatable structure via a smartphone application.
  • the inflatable structure may collapse when not in use into a portable trolley.
  • the invention further discloses a method for inflating an inflatable structure, the method includes the steps of inflating an inflatable structure; gathering readings by a sensor attached to the inflatable structure; detecting continuous increase in variation of the readings over time; activating a blower; checking if the readings returned to normal and deactivating the blower.
  • the smartphone application also controls a lighting in the inflatable structure, all according to the specified timetable.
  • FIG.l is a perspective view of an automatically regulated inflatable structure.
  • FIG. 2 is a schematic example of an interface over a smartphone to remote control and regulate an inflatable structure.
  • FIG.3 is a flowchart of an exemplary method for automatically regulating an inflatable structure.
  • an inflatable structure is provided together with a a blower which is configured to be operated when the inflatable structure becomes unstable usually as a result of an air drop from the inflatable structure.
  • the blower is operated when the inflatable structure becomes less stable taking into consideration a predetermined timetable to avoid activation during a less convenient schedule.
  • the blower that is configured to be triggered and operated by a tilt or acceleration sensor which detects movement or vibrations of the inflatable structure which may suggest instability as a result of a pressure drop inside the inflatable structure.
  • the sensors may detect movement or changes in the speed of movement or its direction.
  • the sensor itself is attached to the top outer surface of the inflatable structure and the sensor outputs is used as a trigger to activate or deactivate the blower as further depicted below.
  • an inflatable structure 1 is comprised of a generally tubular segments that form a base 6, poles 12 and beams 11.
  • the inflatable structure 1 is inflated, via a hose 3, with a blower 2.
  • the base 6 of the inflatable structure 1 is also filled with water through a valve 7, thus providing greater stability to the inflatable structure 1.
  • An accelomter or tilt sensor 5 is attached to the upper top surface of the inflatable structure 1, preferably to the upper portion of a pole 11.
  • the sensor 5 is connected to a programmable microprocessor 13 which is attached to the air pump 2.
  • the programmable microprocessor 13 is configured to receive signals from the sensor 5 via a wire protected inside an insulated sleeve 18 running from the sensor 5 along the pole 12, along the hose 3 and into the microprocessor 13.
  • the microprocessor 13 runs an algorithm to process the signals received by the sensor 5 over time.
  • the microprocessor 13 compares readings before and after the blower 2 is activated to extract reading patterns who represent stability of the structure 1 as opposed to readings of increasingly stronger signals over time reflecting a possible deflation of the structure 1.
  • Momentary strong readings which may be caused by leaning or inadvertently stumbling into a pole 12 for example are therefore disregarded by the microprocessor 13.
  • the accelometers or tilt sensors 5 which may be used are very low cost and abundant as they are mass produced in favor of the smartphone industry, these sensors may detect vibrations, movements orientations etc. When the inflatable structure is stable a vibration sensor will detect relatively constant vibration pattern, however as the inflatable structure losses stability the vibration pattern will increasingly fluctuate over time.
  • Another accelometer 19 is attached to the base of the inflatable structure 1 the information gathered from the lower sensor 19 is transmitted by a wire 20 to the microprocessor 13.
  • the microprocessor 13 compares the readings between sensor 5 and sensor 19 as sensor 19 attached to a high on a pole 12 the moment applied on the sensor 5 is greater thus causing an increase in the readings of the sensor 5.
  • this may suggest a drop in the air pressure of the inflatable structure 1 thus serving as a trigger to activate the blower 2.
  • Other types of sensors or detectors such as air pressure sensors or seismic detectors can also be utilized mutatis mutandis.
  • the microprocessor 13 is also programmed to operate the blower 2 at convenient times, taking into consideration preprogrammed schedule such as meals, rests, prays etc.
  • a smartphone 4 with an integrated acceleration sensor (used as a tilt sensor) which detects tilt of the smartphone 4 is used to monitor the inflatable structure and to wirelessly transmit the readings to a transceiver 21 for processing by the microprocessor

  • the signal processing and the timetable for operating the blower 2 might be run and stored either on the smartphone 4 or on the microprocessor 13.
  • the inflatable structure 1 of the present invention could be used as a Sukkah during the Jewish holiday of Sukkot. Then used as a Sukkah, the inflatable structure 1 may include side covers 9 with windows 8 and door 10.
  • the inflatable structure 1 may also contain illumination means such as LEDs 24the LED's may project light directly into the inflatable structure 1 or through beams 11 to provide illumination effects.
  • the LEDs can be controlled and preprogrammed via an interface on the microprocessor 13 or via a smartphone 4 application as described in FIG. 3.
