Definitions

  • This invention pertains to a shoe, preferably a safety shoe, comprising means capable of monitoring the state of health and safety of workers when engaged in their specific work.
  • the present invention pertains to a shoe fitted with an electronic device that is able to detect and signal anomalous situations in a worker's work that indicate that a worker has had an accident or has been taken ill.
  • the invention is therefore related to the classic sectors of footwear manufacturing and specifically, those of safety footwear which is part of the wider category of Personal Protective Equipment (PPE).
  • PPE Personal Protective Equipment
  • safety shoe is used to define "personal protective equipment capable of protecting feet from external dangers and contact with the ground by using one or more specific technological solutions such as the use of a toe cap made of steel or similar/equivalent material and/or an anti-perforation midsole, special treaded soles, water proofing, heat resistant materials and the use of ankle bone padding and a quick release system, etc.
  • safety footwear includes different types of footwear known as "safety”, “protective” and “work” shoes and boots (whose characteristics, properties and uses are of common knowledge to experts in the field and, for this reason, will not be discussed in detail herein) which, although they have different characteristics and functions, are made using standard manufacturing procedures generally consisting of the sewing and preparation of a upper-midsole part, the application of a sole that is glued or directly injected onto this part and the fastening, using time frames and methods that are common knowledge to experts in the field, of protective and safety elements such as toe caps and/or anti-perforation midsoles, etc.
  • the object of this invention is to offer a solution to at least a part of the problems identified above by providing a safety shoe comprising an electronic system capable of detecting and promptly signalling special conditions that can be interpreted as the result of a work accident or injury to the "rescue personnel" or "worker".
  • Fig. 1 of the safety shoe shows lining 10 and sole 11 comprising, as is known, tread 12 and insole 13.
  • the number 2 graphically indicates the "electronic work accident detection system” which, according to the invention, is built into the safety shoe 1 and is placed inside sole 11 preferably near the area where the heel presses down and substantially coincides with heel 14.
  • the electronic system 2 comprises at least means of detection 20 of physical values considered indicative of a work accident (hereinafter referred to as "representative parameters"), a calculation and control unit 21 for said detected representative parameters and communication devices 22 with an external drive which is able to receive or send data to/from said "electronic work accident detection system" which can promptly alert the rescue and/or safety personnel and the worker who has suffered the work accident.
  • the electronic system 2 in the invention further comprises at least one power source 23 in its electronic components and if this is "rechargeable", a recharging system 24.
  • the said means of detection 20 of parameters representing a work accident may beneficially consist of kinematic sensors 20 that can instantly detect critical situations linked to the movement and/or position of the worker.
  • these kinematic sensors 20 built into the safety shoe 1 may be of a type that can detect and provide the three components of the acceleration vector in relation to their reference axes x-y-z and/or angular velocity (see figures 4a-4b ), which, as will be seen, can be transferred and stored on special volatile memories.
  • these measured values will be compared with predefined thresholds that indicate a "condition of normality".
  • a "condition of normality” is understood to be the values of acceleration and/or angular velocity associated with movements normally performed by a worker in his normal work.
  • detection along one or more "x-y-z" axes of the sensor reference system of acceleration or angular velocity that is abnormal compared with the pre-established reference thresholds should be considered indicative of a work accident or injury since it can be attributed, as previously mentioned, to accidental impacts or knocks caused by machinery, tools or other workers or specific angular stresses.
  • these detected anomalies must continue for a sufficiently long pre-established period of time in order to be considered anomalies; in this way, zero gravitational acceleration or an extended position will not be attributed, respectively, to a simple jump (when getting off machinery, for example) or a fall from a low height or a position assumed by the worker in order to perform a task, for example.
  • Said sensors 20 must therefore be able to repeat the same measurement for a period of time that is considered appropriate at least; a work accident or injury condition is therefore obtained when the parameters measured during said period of time remain at values that are considered abnormal.
  • said sensors 20 will preferably be MEMS sensors (which do not require further explanation since of common knowledge to technicians in the field) capable of producing the data referring to the measured parameter in digital form, i.e. capable of providing digital samples of the measured parameter at a predefined, configurable sampling frequency.
  • said MEMS sensors may consist of an accelerometer with MEMS technology that can measure acceleration and a gyroscope with MEMS technology that measures angular velocity. There is nothing to prevent said MEMS sensors 20 being incorporated in a single solution known as an "Inertial Measurement Unit” (IMU).
  • IMU Inertial Measurement Unit
  • the sensors 20 inform said calculation unit 21, and the microcontroller in particular (of a known type consisting of a CPU, a non-volatile memory, a volatile memory and channels that interface with external peripherals), that the sample is available by generating a special "interrupt" signal.
  • the microcontroller in particular (of a known type consisting of a CPU, a non-volatile memory, a volatile memory and channels that interface with external peripherals), that the sample is available by generating a special "interrupt" signal.
  • the data measured and transmitted by said sensors 20 is temporarily stored, as mentioned, in a special volatile memory on the microcontroller.
  • the microcontroller's main task is, therefore, to read the data for significant parameters of a work accident detected by said sensors 20 each time an interrupt signal is emitted and process it according to the application code (firmware) that is implemented and the programming (for example, according to the defined thresholds) stored in the microcontroller's permanent memory.
  • One of more interrupt lines therefore connect said sensors 20 and microcontroller.
  • At least one of said interrupt lines may be used to signal certain measured parameter values (acceleration and/or angular velocity) which require an immediate response from the microcontroller since they indicate that a serious work accident or injury has occurred and must be reported immediately so that the rescue personnel can promptly intervene.
  • the data received from the sensors 20 are read by the microcontroller by way of known interface buses including but not limited to "3 signal” (called, as is known, SPI) or "2 signal” (called I2C) type buses.
  • Another of the microcontroller's tasks is to configure and update, each time the electronic system of the invention is started up (for example, after purchasing the safety shoe 1 that it is built into), the internal registers of the sensors 20 so that they start to operate according to their described intended use.
  • the microcontroller also controls, by way of a special signal, activation of the sensors that can therefore remain on stand-by until they are required (for example, until the shoes 1 are worn by the worker), with clear advantages for the duration of the power system 23
  • the microcontroller may generate an alarm signal warning the worker and/or rescue personnel and facilitating rescue operations.
  • the "electronic work accident detection system" 2 on the safety shoe 1 may also interface with an external drive so that the data detected by the sensors and processed by the microcontroller can also be beneficially stored remotely and handled by suitable control software to generate, for example, when particularly serious operating conditions that indicate a potentially serious accident occur, a general alarm signal that is not only directed towards the worker who is wearing the safety shoe 1 (in order to speed up the rescue operations or evacuation of the place where the accident occurred) or to signal any malfunctioning detected by the electronic system 2 of the invention.
  • the remote drive may query each electronic system 2 built into the safety shoe 1 in order to check, for example, that the various components are working correctly and/or assess the charge state of its power source or to reprogram its operating parameters (stored, as already mentioned, in the non-volatile memory of the microcontroller).
  • radio transceiver unit also known as a "wireless transceiver” and a radiating element that forms an antenna, having minimal overall dimensions, that is compatible with the unit in the housing in the sole of the safety shoe 1 used for the electronic system 2 of the invention.
  • said antenna is a "ceramic” type one but there is nothing to prevent it from being part of the "electronic work accident detection system” 2 Printed Circuit Board (PCB).
  • PCB Printed Circuit Board
  • safety shoe 1 with said electronic system 2 also comprises at least one acoustic and/or optical signalling device 25 for the worker capable of being activated when one or more of the abnormal conditions detected by the sensors, listed above, occur.
  • Said signalling devices may also be activated if there is malfunctioning in one more components of the "electronic work accident detection system" 2 detected following autodiagnostic procedures or if the power source 23 has discharged.
  • Said power source 23 consists preferably of a rechargeable battery sized according to the size of the electronic system 2 of the invention and its consumption notwithstanding the fact that it must last for at least one working day (equal to approximately 8-10 hours).
  • said batteries may be recharged at the end of each working day using special recharging systems such as electromagnetic induction ones or a classic recharging system that uses a cable that connects the recharging module 24 of the electronic system 2 of the invention to the mains.
  • special recharging systems such as electromagnetic induction ones or a classic recharging system that uses a cable that connects the recharging module 24 of the electronic system 2 of the invention to the mains.
  • the objects of the invention are achieved with the safety shoe 1 with a built-in "electronic work accident detection system” 2 and in particular, the possibility of detecting and promptly signalling special conditions that can be interpreted as the result of a work accident or injury to the "rescue personnel” or to the "worker” thereby reducing the negative consequences (especially damage to health) deriving from said work accident or injury.
