Definitions

  • the user has the obvious disadvantage of not being able to adjust the amplitude and the position of the movement of the shoe along the guide according to taste, requirements and height and, in the final analysis, the area of the body to be massaged.
  • having to position the limit switches by hand is troublesome and moreover obliges the manufacturer to study relatively complicated mechanical systems for supporting and operating the limit switches, which also involve the use of electrical connections made by means of flexible or spiral conductors to enable them to move along the guide.
  • the general scope of this invention is to obviate the aforementioned problems by providing a motor-driven device for moving a guide shoe along a guide, said shoe comprising a support for nozzles delivering jets of water under pressure, in particular inside a shower compartment, with electronic adjustment of the ends of the stroke of the guide shoe along the guide, without the need to use movable limit switches or other mechanical devices.
  • a further scope of this invention is to provide protection against accidental interference between the body of the user and the end of the sliding support protruding into the shower compartment.
  • a device for sliding a guide shoe along a guide by means of a control ratiomotor, comprising an orientable support for nozzles delivering water under pressure, in particular in a shower compartment, characterized by the fact of comprising, in combination, detecting means for detecting the position of the guide shoe along the guide which give numerical data of the position and comparing means for comparing said numerical data with a first numerical value memorized previously in first storage means and a second numerical value memorized in second storage means, said comparing means functioning in order to reverse the rotation of the ratiomotor when the numerical output data from the detecting means is identical to one of the two numerical values memorized previously.
  • a device comprises a guide rail 10, fitting tightly into a housing made in one wall 11 of a shower compartment, along which slides a shoe 12 carrying an articulated support 13 for nozzles delivering jets of water under pressure (for example of the type in which air and water are mixed to obtain jets with a massaging action) connected to a source of water through a flexible hose, neither of which are shown since they can be of any known type and are therefore easily imaginable by any technician.
  • a guide rail 10 fitting tightly into a housing made in one wall 11 of a shower compartment, along which slides a shoe 12 carrying an articulated support 13 for nozzles delivering jets of water under pressure (for example of the type in which air and water are mixed to obtain jets with a massaging action) connected to a source of water through a flexible hose, neither of which are shown since they can be of any known type and are therefore easily imaginable by any technician.
  • the shoe 12 is pulled along the guide 10 by means of a cable 14 which, after passing through passages 15, 16 at the ends of the guide, winds around two pulleys 17, 18, respectively.
  • the cable 14 is fitted with an extension spring 19.
  • the pulleys 17 and 18 are supported, respectively, by supports 20, 21 secured to the structure of the guide.
  • the upper support 20 comprises a housing for a sensor 23 (for example of the optoelectronic type) which detects the passage of holes 24 disposed equally spaced apart around a circumference of the pulley 17.
  • the pulley 17 is driven by means of an electric ratiomotor 25.
  • the passages 15 and 16 are advantageously made watertight so as to prevent the water in the shower compartment from seeping behind the wall 11.
  • the ratiomotor 25 and the sensor 23 are electrically connected to a controller 26 having a control keyboard 27.
  • a preferred embodiment of the controller 26 comprises a to-and-from counting unit 28 which counts the pulses emitted by the sensor 23 when the holes 24 on the pulley 17 pass in front of it.
  • the counter counts either forward or backward depending upon the status of the signal line 30 which indicates the direction of rotation of the ratiomotor 25.
  • the output 29 gives (for example as a binary representation) a numerical datum proportional to the position of the shoe 12 along the guide 10.
  • the perforated pulley 17, the sensor 23 and the counter 28 constitute means for detecting the absolute position of the shoe.
  • the output 29 is connected to the inputs of two storage units 31 and 32 and to one input of a comparator 33 whose other input is connected, by means of an electronic switch 34, to the outputs of the storage units 31 and 32.
  • the output of the comparator 33 is connected by means of an OR 35 to a control unit 36 which controls the direction of rotation of the motor 25 and whose output gives the signal 30 for the direction of rotation of the motor, which pilots the motor through a piloting unit 37 with an overcurrent detecting unit 38 disposed, in series with the motor, at its output.
  • the storage units 31 and 32 have storage enabling inputs 41, 42, respectively, which are connected by means of a second electronic switch 39 to a storage control button 40.
  • the storage units also have clearing inputs connected to a button 43.
  • the electronic switches 34 and 39 are controlled by the signal 30 for direction of rotation of the motor.
  • the device described above operates in the following way.
  • the ratiomotor 25 receives signal from the circuit 26 and begins to move the shoe 12 along the guide 10.
  • the pulses generated when the holes in the pulley (17) pass in front of the sensor 23 change the number in the counter 28 so that its output gives a number proportional to the momentary position of the shoe.
  • the memorizing button 40 is pressed, the number corresponding to the position reached by the shoe at that moment is stored in the memory (for example, number 32 if the electronic switch 39 is disposed as shown in the figure).
  • the output of memory 32 reaches the comparator 33 through the electronic switch 34. Since the numbers arriving at the two inputs of the comparator are the same it emits a pulse at its output which, through the OR circuit, instructs the direction circuit 36 to reverse the direction of rotation of the motor. Thus the shoe 12 reverses its direction of movement along the guide.
  • the signal 30 shifts the switches to their other position and reverses the counting direction of the counter 28.
  • the output of memory 31 reaches the comparator 23 through the electronic switch 34. Since the numbers arriving at the two outputs of the comparator are the same it emits a pulse at its output which, through the OR circuit, instructs the direction circuit 36 to reverse the direction of rotation of the motor again. Thus the shoe 12 again reverses its direction of movement along the guide and the switches 34 and 39 return to their original position while the counter 28 reverses its counting direction again.
  • the comparator will have inputs, connected to the counter and to the memory 32, with the same number and will consequently reverse the direction of movement of the shoe which, on reaching the position corresponding to the second time the button 40 was pressed, will again reverse direction (since the comparator has inputs, connected to the counter and to the memory, which are identical) and so on, with the shoe continuing to move to-and-from between the two memorized points.
  • the direction of movement of the shoe is controlled by the comparator 33 as well as by the overcurrent detector 38.
  • This detector 38 emits a pulse, to reverse the direction of rotation of the motor, which reaches the control unit 36, through the OR 35, whenever the current absorbed by the motor exceeds a threshold value advantageously set slightly above the rated value of current normally absorbed by the motor when it draws the shoe along the guide.
  • controller 26 To ensure that the controller 26 is ready to operate when the power is switched on it is designed in such a way that as soon as it is powered it clears the memories and shifts the shoe 12 to one end thereby also clearing the counter 27.
  • buttons could be used for controlling the upward or downward movement of the support 13 which serve to shift said support to a pre-established position along the guide; the support could then be maintained in this position indefinitely until shifted to another position or until the continuous reciprocating movement between two points is activated, as described above.
  • the sliding parts can be advantageously made of, or covered with, teflon in order to reduce friction.
