Description

"Motor device for double curtains and curtains"

  The invention to which we refer

  this in the body of this specification and with the help of the accompanying drawings, deals with a motor device started electrically by

  built-in rechargeable batteries, for sliding

  ment of double curtains and curtains both during their opening and closing movement, it can be switched on with a button located outside

  from the environment of the curtain itself, and by a poi-

  suspended gene located in the own device, thanks

  to which it will work both ways, it rem-

  advantageously places the means currently used which are generally controlled by hand. It has structural and constitutive characteristics which differ greatly from the various known means,

  it is for these reasons joined to the qualities of new

  validity and practicality which is considered to be a sufficient basis for obtaining the privilege

  exclusivity requested, with regard to its fa-

  brication and sale by the holder in Spain, following this utility model register to which

he has recourse.

  The motor device for double curtains and

  curtains to which we refer, includes essen-

  a hermetically sealed housing which

  holds the starting motor, on the projecting axis of which, an endless device connected to a

  knurled bearing placed in contact with the anterior plane

  laughing and with guide bearings housed in their

  central longitudinal groove that keeps all

  days the rail in contact with the knurled bearing and

  force to carry out a linear displacement.

  On one side of the housing fitted with the motor elements there is a projecting arm, on the end of which is mounted a microswitch for starting the device, on this microswitch a ring will be mounted

  from which a rope or cable will hang so that the user can

  pull on it and put the microswitch on by giving rise to the commissioning of the device and stop it on a determined point This microswitch will be closely linked to another microswitch housed in the housing which will only be activated at the end of the race in

  the positions of the curtains fully unfolded or fully

  slightly folded, so that starting it causes the mechanism to stop, and leaving it ready to be started again, the direction of rotation

  will be contrary to the one in which he turned an-

later.

  To cause the direction of rotation to be reversed

  tion of the motor, the movable housing has on its rear and upper part of a movable strip equipped on its ends with angle tabs which are housed in the existing channel on the rail, and descending arms which are housed in said housing, so that, when the latter reaches the end of its travel, the strip moves by activating one of the arms housed in the housing, the stop microswitch or

  inversion until a new start.

  The protruding side arm of the fitted housing

  of a starting microswitch, can be eli-

  mined and have on the wall and near the curtain an

  manual switch which will do the same service.

  The figures shown in the accompanying drawings show an embodiment described below, drawings in which: Figure 1 shows a longitudinal front view of the motor device for double curtains and curtains, mounted on a single steering rail, it can also be incorporated on rails for two-way double curtains, it is constituted by a hanging box movable on the same rail, it carries in its movement the end of the curtain and it carries, on

  the side, a protruding arm fitted with an ac microswitch

  activated by the user by simply pulling the above cord

  hanged. Figure 2 shows a longitudinal plan view of the assembly shown in Figure 1, we see the knurled drive bearing pressed on the own rail on the front plane and the rear guide bearings housed in the existing channel or groove on said rail, FIG. 3 shows a rear longitudinal view in elevation of the device where one can observe the movable upper strip actuated at the end of the race, by angle folds housed in the

  groove or channel of the own rail, and arms down

  dants housed in the housing that will start a

  stop and reversing microswitch.

  Always referring to the an-

  attached, it should be emphasized that in the various

  gures exhibited in these we have added

  digital annotations related to the

  reviews carried out below of their characteristics

  ques and functioning by facilitating this ma-

  nier their immediate location: the reference 1 is the conventional rail closed externally and equipped on its rear part with a groove or channel 2, which extends longitudinally on the rail 1 to which will be mounted the casing 3 movable in a suspended manner

  down, it will have for that on its upper part

  périeur, a knurled bearing 4 which constitutes the driving means started by a motor and an endless device located in the housing 3 and which is supported and in contact with the center of the external plane of the rail, while later bearings will be placed guide 5 which will be housed in the central part having

  the largest diameter in channel 2 of the rail.

  In box 3 we find bat-

  Rechargeable electric lines, which can be plugged in

  chées to the supply network, by cables 6, the

  housing comprising on its front part, an inter-

  breaker 7 which will leave the assembly without service, as long

that the batteries will be charged.

  On one side of the movable housing 3, the arm 8 is placed, which can be placed on the other side, the arm of which comprises the microswitch 9 which is started by the ring 10 from which hangs a cord 11 so that

  the user can put the mechanism into service in ti-

  rant simply down, you can remove the arm 8 to place a pulsator switch on some

  point that will perform this function.

  The movable box 3 on the upper part

  rear and behind the guide bearings 5,

  takes a movable strip 12 with two position points along the pivot 13 secured to the housing 3 which will be housed in one of the notches 14 formed on the own strip and which carries on its ends, the arms in elevation 15 equipped with angle profiles 16 which will be housed in the rear groove 2 of the rail 1, so that at the end of the travel in both directions they abut against the end of travel 17 by forcing the strip 12 to move and by the descending arms 18 housed in the housing 3, they activate an interior switch which gives rise to the stopping of

  the motor element and reverses the current input at the mo-

  tor, so that a subsequent commissioning causes a contrary displacement of the movable case and, by

  Therefore, double curtain or curtain.

  The device will have various attachment points

  ge 19 for curtain supports and a guide

posterior 20 for the cord.

  Considering as amply described all and each of the parts which constitute the motor device for double curtains and curtains which are the subject of the invention, it is necessary to emphasize the possibility of

  what their different parts can be made

  ques in varieties of materials, sizes and shapes-

  mes, these constructive variations advised by practice could also be introduced into their constitution, however that these will not alter the essential points of which the present

  Utility Model filing is subject to.
