Definitions

  • the present invention relates to a retaining stop for doors and the like, of the type performing the function of a stop and further allowing to keep the door in open position.
  • stops for doors that are anchored to the ground and are provided with a resilient member in order to prevent the door from striking against the wall or against an item of furniture when it is opened; some of this stops are combined with means to retain the door in open position, such that they have a double stopping and retaining function.
  • This retainers consist e.g. in a thin strip, narrow and elongate, mounted at one end on the stop itself, which can turn around the stop and pass under the door.
  • the strip has a projection arranged on its free end, such that when the retainer is in an inoperative position the door can be opened against the stop and then the strip can be moved under the door until it is placed in front of it, such that the door is retained between the stop and the projection at the end of the strip.
  • This assembly has obvious drawbacks, mainly those arising from the need for manual handling in order to withdraw the operative presence of the projection and release the door in order to close it.
  • retaining stops include a magnet which attracts a metal strip fixed to the door; in some cases, the stop member and the magnet are mounted on opposite sides of a rotatable base, whereby change from the stop function to the retaining function involves turning the base in order to make the retaining magnet face the door.
  • Another known arrangement consists in placing a rotatable bipolar magnet on a base secured to the ground, and a simple magnet on the door, such that by turning the bipolar magnet on the base it is possible to achieve that the magnets facing each other have the same polarity, thereby not attracting each other (stop function) or that the magnets facing each other have opposite polarities, thereby attracting each other (retaining function).
  • the object of the present invention is to provide a retaining stop for doors which does not have the mentioned drawbacks, which can be fitted to any kind of door and which is comfortable to use.
  • the retaining stop of the invention is of the type comprising means for being anchored to the ground, a front resilient member which constitutes a stop to the opening of the door or the like, and a magnet that can cooperate with a metal strip associated to the door or the like in order to keep the latter in open position.
  • This retaining stop is characterized in that the magnet is mounted and guided to be displaceable between an inoperative position, in which it is kept withdrawn from the surface of contact between the resilient member and the door or the like, such that it is not attracted by the metal strip arranged on the door when the latter contacts the stop, and an operative position, in which the magnet is advanced to the maximum extent towards the front part of the resilient member, attracted by the metal strip arranged on the door when the latter is pressed sufficiently to bring the metal strip of the door near enough to the magnet such as to cause said advancement and to make the magnet contact the metal strip of the door in order to keep the latter retained; and in that it comprises means for displacing the magnet automatically from said operative position to said inoperative position withdrawn in its housing when the door is released from the retaining stop.
  • Shifting of the magnet to the operative position does not occur by the simple contact of the door against the retaining stop, even if the door hits the stop with a certain force.
  • the door exerts a special pressure on the stop, such that the front resilient portion of the stop becomes deformed, the metal strip of the door thus approaches the magnet which is at the rear of the stop, until the magnet is attracted by the metal strip and therefore advances until it directly contacts the metal strip fixed to the door, whereby the latter is positively retained.
  • the means for automatically displacing the magnet from said operative position to said inoperative position comprise a metal member arranged in a position which is opposite to that of the advancement of the magnet to contact the door.
  • This mechanism is simple and reliable, since it is not subject to suffering failures and it does not wear with time, and further its assembly has no difficulty.
  • the magnet is slidably arranged within a housing of non-magnetic material having the resilient stop member engaged on the front part thereof.
  • This arrangement allows the device to have a smooth and aesthetically pleasant exterior aspect, and protects the magnet from dust, blows, etc.
  • the metal member which causes the magnet to withdraw to the inoperative position is a plate bent at right angles at one of its ends, which is arranged with this bent end fitted with play between a side wall and a rear wall of the magnet housing, and having the other end free to be displaced following the movement of the magnet.
  • This arrangement of the movable plate that can undergo an angular displacement around one end thereof allows to keep one end always near the magnet, even when the latter has travelled forward to its operative position, and this assists the subsequent attraction of the magnet by the plate and the return of the magnet to the inoperative position, once the door is released.
  • the magnet is arranged between two parallel metal sheets, which are provided on a portion of their length with side projections limiting their forward travel.
  • the metal sheets are further provided with a rear projection in a portion of their width, preventing the metal plate from being in direct contact with the whole width of the magnet.
  • the side projections of the two metal sheets that sandwich and guide the magnet in its movement abut against the front part of the inner box of the body of the device, and at the same time the rear projection prevents the return plate from being in direct contact with the whole width of the magnet.
  • the presence of these sheets sandwiching the magnet allows the latter to be a simple conventional rectangular block.
  • its overall housing is constituted by a base and a cover, having inner projections for mutual engagement of the base and cover and for the retention of the front resilient member, as well as for guiding the magnet.
  • Figure 1 shows the outer aspect of the retaining stop of the invention, indicated generally with reference 1.
  • Said stop has on the front part thereof a resilient member 2, made of a block of elastomeric material, a base 3 (which can be seen in figure 2) and a cover 4, these parts constituting the basic structure of the device.
  • the resilient member 2, shown in plan view and in cross-section in figure 3, is coupled by means of two side lugs 2b is a gap defined between the base 3 and the cover 4.
  • the magnet 5 is inserted between two sheets 6 that are attached to it.
  • a metal plate 7 arranged between the rear side of the magnet 5 and the rear wall 3a of the base 3. The shape and function of this plate 7 will be described below.
  • the magnet 5 can travel in the direction of arrow A, between the position of figure 2, in which it is completely withdrawn towards the rear of its housing, and a position in which its front side protrudes slightly from the resilient member.
  • the base 3 and the cover 4 have elongate inner projections 3b, arranged in the direction of displacement of the magnet, to facilitate its movement.
  • the door 10 facing the retaining stop is provided with a metal strip 11, arranged to face and engage the magnet 5 when the device has to act as a retainer.
  • the magnet 5 and the plate 7 are in the same position shown in figures 1 and 2.
  • the base has the shape of a portion of a circle, from which rises a rectangular enclosure formed by the rear wall 3a and the two side walls 3c. Between the end of one of the side walls 3c and the rear wall 3a there is a gap through which extends and is inserted the metal plate 7.
  • the sheets 6 that sandwich the magnet 5 have the shape shown in figures 4,5,6, with a rear projection 6a and a pair of side projections 6b; the magnet, on the contrary, is a rectangular member without projections like those of the sheets 6, in order to avoid a complex manufacture.
  • the side projections 6b guide the magnet laterally, and at the same time serve as a stop to its forward movement, when they engage the front shoulders 3d of the base 3; the projection 6a prevents the metal plate 7 from engaging directly the magnet in all the width thereof, in order to avoid an excessive attraction force.
  • the device is normally in the position of figure 4, with the magnet withdrawn inside its housing, attracted by the metal plate 7.
  • the resilient member 2 tends to recover its initial shape: as a consequence of the elastic force exerted by the resilient member 2, and since the magnet 5 has a larger contact surface with the strip 11 than with the plate 7, it disengages from the latter and travels forward to the position of figure 6. This advancement is limited by the side projections 6b.
  • the retaining stop naturally comprises means for anchoring it to the ground, such as a self-adhesive surface on its lower side; it may also include bores 8 on the base 3 (figure 4) in order to anchor it by means of screws if desired, etc.
  • the housing, the resilient member and the magnet can have different shapes from those shown, and can also be made up of several parts.
  • the metal plate attracting the magnet to drive it back it to the withdrawn position could be substituted by a different metal member; the same function could also be performed by a spring arranged in compressed condition in front of the magnet or by any other element ensuring the return of the magnet to its withdrawn position upon the lack of presence of a facing metal member.
