Definitions

  • the present invention relates to a device to rotate an element about an axis as defined by the preamble of claim 1.
  • a device is known from EP-A- 0 279 236.
  • the device according to the present invention could be applied to open and close gates, automatic doors, safety doors for access to presses, gates of transport systems for the disabled, etc.
  • Devices are known at present to effect the opening and closing of gates by means of rotation, which generally comprise a telescopic arm, disposed externally and angled with respect to the plane of the gate shutter.
  • the said arm is provided with means (e.g. a hydraulic piston) of opening and closing the shutter of the gate.
  • the presence of the moving external arm may also be source of danger to the users, and for children in particular.
  • the aim of the present invention is to solve the aforementioned problems by a device to effect the rotation of an element about an axis, which occupies minimum space, operates in a safe way, is protected from the outside and cannot be pushed open.
  • the device is provided with a first fixed sleeve and a second rotatable sleeve, coaxial and external to the first sleeve, and means of transmitting the rotation of the piston to said second sleeve.
  • the means of rotating the piston comprises preferably a pair of curved slots cut into the first sleeve, and a pin fitted to and projecting from the piston to engage said slots.
  • the means of transmitting the rotation from the piston to the external sleeve comprises at least one vertical slot cut into the external sleeve, said slot being engaged by said pin.
  • the curved slot comprises an first section parallel to said axis of rotation and a second helicoidal section.
  • the device according to the present invention offers firstly the advantage that the means that causes the rotation of the element about an axis - and therefore the movement of opening and closing of the shutter of the gate - are housed within a fixed location. Since the location of such means of movement is in association with the axis of rotation of the shutter of the gate, minimum encumbrance is caused. Moreover, thanks to such a system, the possibility of a user accidentally coming into contact with said means of movement is eliminated. Finally, the device according to the present invention is able to prevent the operation of the rotatable element by pushing.
  • the piston 7 operates with a translational-rotary movement which can be divided into two components: an first translational component along a substantially vertical axis and a second rotational component about said vertical axis.
  • the rotation of the piston 7 is transmitted, by appropriate means described below, to the element 6A to be rotated. In this way the element 6A is made to rotate about the said vertical axis, thus causing the gate to open.
  • the device 1 to effect the rotation of an element about an axis shown in figure 1 comprises a piston 7 which moves vertically along the axis of rotation, inside a first sleeve 4 and can be rotated inside the said sleeve.
  • a second sleeve 5 external to the first sleeve 4 and coaxial with said first sleeve 4 and with the piston 7.
  • the first or internal sleeve 4 is fixed and fast to the base 16 of the device 1, while the second sleeve 5 is rotatable.
  • the piston 7 is of a hydraulic type and is provided with a rod 3 and a gas buffer 15 to return it to the bottom dead center.
  • FIG. 1 there is a third sleeve 6, external to the sleeves 4 and 5, whose function is that of supporting the rotatable element 6A.
  • the third sleeve 6 is therefore fast to the rotatable element 6A and is rotatable with the second sleeve 5.
  • an electric contact 2 In the lower part of the device 1 there is an electric contact 2, whose function will be illustrated below.
  • the device 1 is in alignment with the axis of rotation of the shutter of the gate on which it acts.
  • Figure 2 shows some details of the device 1.
  • a substantially horizontal pin 11 fitted to the piston 7 which engages both the internal sleeve 4 and the second sleeve 5.
  • a pair of curved slots 10 cut into the internal fixed sleeve 4.
  • each of the curved slots 10 is helicoidal in profile, and symmetrical to each other, so that they are both engaged by opposite ends of the pin 11.
  • each of the curved slots 10 one of which is shown in planar development in figure 3, comprises a first vertical section 13 parallel to the axis of rotation and a second curved section 14.
  • Vertical slots in the present description means slots that are parallel to the axis of rotation.
  • the pin 11 is provided with portions projecting from the piston, which engage the two curved slots 10 and the two vertical slots 9.
  • Pin 11 is thus constituting both the means of causing a rotation of the piston and the means of transmitting this rotation to the second sleeve and to the element 6A.
  • the opening of the element 6A occurs in the following way: the hydraulic piston 7 is forced upwards by the oil entering the cylinder.
  • the piston 7 in rising drags the pin 11 to which it is fast and said pin 11 runs in the pair of curved slots 10 cut into the internal sleeve 4.
  • the pin 11 After having travelled the first straight section 13 of the curved slots 10, the pin 11 meets the curved section 14 of the curved slots 10 and is forced to rotate on a vertical axis.
  • the closing of the gate is effected (once the oil pressure is removed) by the piston 7 returning to its starting position under the influence of the gas buffer 15 or of similar spring means.
  • the return of the piston 7 forces the pin 11 to retrace its path described above along the curved slots 10. Therefore the piston 7 rotates in the opposite direction, causing rotation of the second sleeve 5, of the third sleeve 6 and of the element 6A in the direction of closing the gate.
  • Such contact 2 referred to as a "consent contact” has a safety function, in that it communicates the consent to the carrying out of a following operation to other devices or potentially dangerous machinery, for instance a press or a system of transport for disabled persons.
  • the electric contact 2 closes the corresponding electric circuits only when the piston 7 has reached its own bottom dead center in its downward movement, that is when closure of the gate has been verified.
  • the device 1 according to the present invention could be applied to gates of different sizes and weight, since it is possible to regulate the strength of the rotation force imposed on the shutter by adjusting the oil pressure.
