Definitions

  • the present invention relates to devices for doors, and more specifically to devices for doors that allow the decoupling of a drive unit, thereby enabling said door to be operated manually.
  • Automatic doors comprise a drive unit (generally at least one motor) to cause their automatic opening and/or closure.
  • the drawback with these doors is that a cut in the power supply could result in undesirable situations such as the inability to open the door when attempting to take a car out of a garage for example (a circumstance in which the door is closed when the fault occurs), or the inability to close said door, resulting in a situation of insecurity (a circumstance in which the door is open when the fault occurs).
  • the prior art contains known devices for doors of this type, which resolve this drawback by allowing the door to be decoupled from the drive unit, so that said door may be opened and/or closed by acting manually upon it.
  • Document US 5581939 A discloses a device of this type.
  • the device comprises a drive unit, whose actuation is transmitted to the door by means of transmission means, thereby causing the automatic opening and/or closure of the door, unclamping means, which are arranged in an automatic position where they enable the automatic action and the door, and which are arranged in a manual position where the drive unit is decoupled from the door by means of the decoupling of the transmission means from the drive unit, and operating means to cause the movement of the unclamping means from the automatic position to the manual position.
  • the operating means comprise a lever with one end arranged between two pieces of the unclamping means through which passes a shaft of the door, said end pushing one of them to cause, when a user acts on said lever, the movement of said unclamping means to the manual position.
  • the device for an automatic door of the invention comprises a drive unit that acts on the door to open and/or close it automatically, the action of the drive unit being transmitted to the door by means of transmission means attached to said door and to the drive unit, unclamping means, which are arranged in an automatic position to enable the automatic action on the door, and which are arranged in a manual position to prevent said action, and operating means to cause the manual movement of the unclamping means from the automatic position to the manual position.
  • the installation of the device is made easier as it is not necessary to couple it to a possible shaft on the door, which would involve the need for a specific shaft to support these types of devices or the adaptation of a conventional shaft to support these types of devices.
  • the device of the invention can be installed on any door, not only on new ones, as it does not require any specific shaft or element to support said device, as said device is associated to the transmission means that said door can have.
  • FIG 1 shows an embodiment of the device 100 of the invention, for doors, which is preferably used for garage doors, as shown in the example in Figure 2 .
  • Said device 100 comprises a drive unit M, which preferably comprises a non-reversible motor that acts on the door 2 to open and/or close it automatically, the action of the drive unit M being transmitted to the door 2 by means of transmission means 1 attached to said door 2 and the drive unit M.
  • the motor comprises a motor shaft M1, the rotation of which is transmitted to the transmission means 1, said transmission means 1 causing the opening and/or closure of said door 2 in accordance with the direction of rotation of said motor shaft M1.
  • the device 100 also comprises unclamping means 3, which, arranged in an automatic position P1 shown in Figure 3 , enable the automatic action of the drive unit 1 on the door 2, and which, arranged in a manual position P2 shown in Figure 4 , prevent said automatic action, and operating means 4 to cause the manual movement of the unclamping means 3 from the automatic position P1 to the manual position P2.
  • unclamping means 3 As a result of the movement of the unclamping means 3 from the automatic position P1 to the manual position P2, the drive unit M is decoupled from the transmission means 1, said transmission means 1 remaining attached to the door 2 at all times, so that a user can open and/or close the door 2 manually by acting on said door 2.
  • the drive unit M causes the automatic opening and/or closure of the door 2.
  • the unclamping means 3 are arranged in an automatic position P1.
  • the drive unit M preferably comprises a non-reversible motor, as a result of which it is not possible to act directly on the door 2 or on the transmission means 1 manually to open or close said door 2.
  • the unclamping means 3 are designed to resolve this drawback, so that when a failure of this type occurs (or when the user wishes to open the door 2 manually instead of automatically), said unclamping means 3 enable the user to open and/or close the door 2 manually, by acting directly on said door 2 for example.
  • the user acts first of all on the unclamping means 3, causing the movement of said unclamping means 3 from the automatic position P1 to the manual position P2.
  • the movement of said unclamping means 3 from the automatic position P1 to the manual position P2 causes the transmission means 1 to become decoupled from the drive unit M, so that said drive unit M offers no resistance to a manual action on the door 2.
  • a safe device 100 is also obtained in that if the drive unit M operates accidentally or unexpectedly (if the power supply comes back on, for example), this does not affect the door 2 or the transmission means 1 or the user acting on the door 2.
  • the device 100 can be installed in a very simple manner as it is not necessary to couple it to a possible shaft 20 (or drive rod) of the door 2 and on which said door 2 is supported and the rotation of which causes the opening and/or closure of said door 2, which would involve a specific shaft for supporting these types of devices 100, this device 100 being capable of being used even in doors 2 not requiring a shaft 20 of this type.
  • Figure 2 shows an embodiment of the device 100 of the invention coupled or associated to a door 2, said door 2 comprising a shaft 20 of this type.
  • Said device 100 may also be installed in any door 2, not only in new ones and/or doors that comprise a shaft 20, as it does not require a shaft 20 or any specific member to support said device 100, as said device 100 is connected to the transmission means 1 attached to the door 2.
  • FIG. 5 is an exploded view of an embodiment of the elements that form part of the unclamping means 3.
  • Said unclamping means 3 comprise a transmission member 39 that cooperates with the transmission means 1 to transmit the action of the drive unit M.
  • the device 100 comprises a casing 102 that covers, at least partially, both the drive unit M and the unclamping means 3, and which is fixed to a structure of the door 2 not shown in the Figures.
  • the transmission member 39 is attached with freedom of rotation to said casing 102, preferably to a wall 101 of said casing 102 that is fixed to the structure of said door 2, but is unable to move longitudinally.
  • the transmission means 1 preferably comprise a chain 11 or an equivalent member and a pulley 12 or an equivalent member, said chain 11 connecting the pulley 12 and the transmission member 39.
  • Said transmission member 39 is not covered by the casing 102, so that when the device 100 is installed the chain 11 (or equivalent means) of the transmission means 1 can be fitted in a simple manner.
  • the drive unit M comprises a motor shaft M1 that rotates when an automatic action of the drive unit M is caused, said rotation being transmitted to the pulley 12 by means of said transmission member 39, the rotation of said pulley 12 causing the opening and/or closure of the door 2.
  • Said pulley 12 is associated to the door 2 by the shaft 20 or by another means that causes the opening and/or closure of said door 2 with the rotation of said pulley 12.
  • the motor shaft M1 is associated to the transmission member 39 with the unclamping means 3 in the automatic position P1, thereby causing the decoupling of said motor shaft M1 from said transmission member 39 when the movement to the manual position P2 is caused.
  • the door 2 can be acted on manually to open and/or close it without the drive unit M preventing or resisting this, and in a safe manner.
  • the transmission member 39 is a revolving member and is preferably passed through by the motor shaft M1 of the drive unit M, as shown in Figures 3 and 4 , being attached to said motor shaft M1 with freedom of rotation, said transmission member 39 not rotating together with said motor shaft M1 by itself.
  • the unclamping means 3 comprise a decoupling piece 33 that comprises a hollow revolving body, which is passed through by the motor shaft M1 and is attached with freedom of longitudinal movement to said motor shaft M1, rotating in conjunction with said motor shaft M1, and which is associated to the transmission member 39 when said unclamping means 3 are in the automatic position P1.
  • the motor shaft M1 comprises a segment M1a that is preferably grooved or has a cotter pin, for example, thanks to which its rotation is transmitted to the decoupling piece 33, although said segment M1a may also comprise any arrangement that enables a longitudinal movement of said decoupling piece 33 in relation to said motor shaft M1, at the same time as said decoupling piece 33 rotates in conjunction with said motor shaft M1.
  • the decoupling piece 33 rotates in conjunction with the motor shaft M1, so that with the unclamping means 3 in the automatic position P1, said decoupling piece 33 transmits the rotation of the motor shaft M1 to the transmission member 39, by means of the rotation of which the automatic opening and/or closure of the door 2 is caused in accordance with the direction of rotation.
  • the decoupling piece 33 pulls the transmission member 39 in its rotation in the automatic position P1, said transmission member 39 comprising a housing 39a and the decoupling piece 33 comprising a projection 33a that is housed in said housing 39a when the unclamping means 3 are in the automatic position P1, although any other arrangement that enables the transmission member 39 to be pulled by the decoupling piece 33 is also possible.
  • the operating means 4 are attached to the decoupling piece 33, so that when said operating means 4 are acted on it causes the longitudinal movement of the decoupling piece 33 in relation to the motor shaft M1 and in relation to the transmission member 39, becoming decoupled from said transmission member 39 when the movement of the unclamping means 3 from the automatic position P1 to the manual position P2 is caused, or becoming attached to said transmission member 39 when the reverse movement is caused.
  • the unclamping means 3 also comprise an unclamping bushing member 30 that cooperates with the decoupling piece 33 when the unclamping means 3 move to the manual position P2, and on which the operating means 4 act directly.
  • Said unclamping bushing member 30 is a revolving body and rotates, in one direction or another, when said operating means 4 are acted on, said rotation causing the longitudinal movement of said decoupling piece 33 in one direction or another.
  • the unclamping means 3 also comprise a static guide piece 31, associated without freedom of movement to the casing 102 (preferably to the wall 101), which cooperates with the unclamping bushing member 30 when said unclamping bushing member 30 rotates, said unclamping bushing member 30 moving longitudinally as a result of said cooperation at the same time as it rotates.
  • Said unclamping bushing member 30 is housed at least partially in the guide piece 31, said unclamping bushing member 30 comprising an external surface that cooperates with an internal surface of the guide piece 31, both surfaces comprising a shape that is such that with the rotation of the unclamping bushing member 30 caused by the operating means 4, said unclamping bushing member 30 also moves longitudinally.
  • the external surface of the unclamping bushing member 30 comprises a groove 30b and the internal surface of the guide piece 31 comprises at least one pin 31 a that moves along the groove when the operating piece 30 rotates (really the pin 31a remains static and it is the unclamping bushing member 30 that moves).
  • the groove 30b extends in a helicoidal manner, so that when the operating piece 30 rotates, due to the cooperation between the projection and the helicoidal groove 30b, said unclamping bushing member 30 moves longitudinally. Said longitudinal movement of the unclamping bushing member 30 directly causes the longitudinal movement of the decoupling piece 33.
  • the unclamping bushing member 30 pushes the decoupling piece 33, moving it longitudinally, said unclamping means 3 comprising a spring 34 that is associated at one end to a body M2 of the drive unit M and at the other end to the decoupling piece 33, which is compressed with said longitudinal movement of said decoupling piece 33 and which is coiled around a section of the motor shaft M1, said spring 34 causing said decoupling piece 33 to return to its original position when the unclamping bushing member 30 moves longitudinally in the opposite direction when, by means of the operating means 4, the movement of the unclamping means 3 to the automatic position P1 is caused.
  • the unclamping bushing member 30 comprises an inner wall 30a that pushes the decoupling piece 33 (preferably a projection 33a of said decoupling piece 33) when said unclamping bushing member 30 moves during the movement of the unclamping means 3 to the manual position P2.
  • said decoupling piece 33 does not support any pressure and the spring 34 pushes and decompresses it until the projection 33a cooperates once more with the inner wall 30a.
  • the operating means 4 preferably comprise a chain, a rope or an equivalent member, and are fixed to the unclamping bushing member 30 at at least one fixing point, said unclamping bushing member 30 being capable of comprising, for example, an outer groove 30c for guiding the movement of said operating means 4 and preventing said operating means 4 from jamming, for example.
  • the operating means 4 extend to both sides of said unclamping bushing member 30, so that when the user acts on the extension of one side it causes the rotation of the unclamping bushing member 30 in one direction, and causes the rotation in the opposite direction when the user acts on the extension of the other side.
