Definitions

  • the present invention relates to a closure device particularly for drains.
  • Some of these devices applied for example to tubs, consist of a knob which can be operated by the user; the rotation of said knob directly lifts or lowers the plug at a cage-like element that is sealingly associable with a conical body at the drain of the tub.
  • a similar mechanical system is used in sinks, requiring the movement of a rod which in turn can move the plug vertically.
  • said conventional devices cannot be used for containers that may hold corrosive and toxic liquids, as it may be necessary to dip into the liquid and directly access the plug or the drain of the container.
  • said devices are considerably bulky and mechanically complicated, forcing the manufacturer to provide a series of transmissions of various lengths depending on the application, with considerable effort of the installer.
  • the aim of the present invention is therefore to thus eliminate the described technical problems, thus solving the drawbacks of the prior art, by providing a device that allows to close plugs of containers for water or liquids, including corrosive and toxic liquids, from a distance, therefore without dipping into the liquid to directly access the drain of the container, and is structurally simple and can be manufactured with a small number of components.
  • an important object is to provide a device that has a limited bulk and can be installed easily.
  • Another important object is to provide a device that is structurally simple and can be applied so as to allow activation at the desired distance from the drain so as to always allow easy installation and easy activation on the user's part.
  • Another object is to provide a device that limits the number of parts that the manufacturer has to store.
  • Another object is to provide a device that associates with the preceding characteristics those of having low manufacturing costs and of being easy to maintain.
  • a closure device particularly for drains comprising a conical body and a cage-like element, which comprises a closure plug, that can be sealingly associated with each other at the bottom of a container, characterized in that it comprises a first pneumatic actuation unit that can be operated by the user and actuates at least one second actuation unit for selectively closing or opening said plug.
  • the reference numeral 1 generally designates a drain that comprises a conical body 2 that can be associated below the drain hole of a container, such as a tub or a sink, with which it is possible to associate sealingly, by means of appropriate gaskets, a cage-like element 3 provided with a first hole 4, the axis whereof coincides with the axis of a second hole 5 that is formed axially on the body 2 and is adapted to accommodate the stem 6 of a plug 7 the head 8 whereof can sealingly seal an adapted first seat 9 formed on the cage-like element 3.
  • the closure device is also constituted by a first pneumatic actuation unit 10, which is placed in a region that is handy for the user at a desired distance from the drain 1.
  • Said first unit 10 comprises a knob 11 that can be accessed by the user; its stem 12 is rotatably associated at a suitable container 13, with which it is possible to associate, on the opposite side with respect to the knob 11, a hollow element 14 having at least one discharge duct 15.
  • Suitable cylinders 16 are inserted within said container 13 and said hollow element 14; a positive cam 17 and a suitable pair of pistons 18 are formed therein.
  • Said pistons slide sealingly within the hollow element 14, forming an air injection or suction chamber that is connected to the discharge duct 15.
  • the cylinders 16 When the knob 11 is turned, the cylinders 16, by means of the cam 17, turn, for example, clockwise, actuating the pair of pistons 18, for example with a sequence that moves a first piston downward, then a second piston downward, then the first piston upward, and then the second piston upward.
  • the shape of the cam 17 also allows to keep the first and second pistons in the lowered position (which lies between the position in which the piston 2 is directed downward and the piston 1 is directed upward) even in the presence of forces that may tend to move the pair of pistons 18 upward.
  • One or more hoses 20 are associated with the discharge duct 15 by virtue of suitable engagement means 19; said hoses can in turn be associated, at their other end, with additional engagement means 21 that are connected to a delivery duct 22 formed below the body 2.
  • Said delivery duct 22 is connected to a chamber 23 which is obtained by associating a second cylinder 24 below and axially to the body 2.
  • the head 25 of a piston 26 slides sealingly within said second cylinder 24, and the stem 27 of said piston 26 slides at a suitable axial hole formed on the second cylinder 24.
  • a spring 28 is arranged coaxially to said stem 27.
  • the stem 6 of the plug 7 is connected to the chamber 23 and lies above, or is associated with, the head 25 of the piston 26.
  • the operation of the device is thus as follows: the spring 28 arranged coaxially to the stem 27 of the piston 26, in the absence of pneumatic pressure inside the chamber 23, keeps the head 8 of the plug 7 raised with respect to the first seat 9, thus allowing to discharge the content of the tub or sink.
  • a rotation of the knob 11 entails, for example, the downward movement of the pair of pistons 18, thus compressing the air that flows, through the discharge duct 15 formed on the element 14 and the hoses 20, into the delivery duct 22, pushing the piston 26 downward.
  • the plug 7 moves downward, preventing the discharge of the liquid; the descent of the plug 7 occurs by gravity or by connection to the head 25 of the piston 26.
  • the invention has achieved the intended aim and objects, a device having been provided that allows to remotely close drains and is constituted by a limited number of components that are simple to apply and have a low cost.
  • the invention is therefore structurally very simple; the first actuation unit can be placed at the desired distance with respect to the second unit, and it is sufficient to merely connect the two units by means of a conventional hose, which can even follow long and/or convoluted paths without altering the activation of the device.
  • closure device according to the invention is of course susceptible of numerous modifications and variations, all of which are within the scope of the same inventive concept.
  • figure 3 illustrates another embodiment of the second unit, wherein the second cylinder 124 is formed radially with respect to the axis of body 102 and thus protrudes approximately at right angle to the stem 106 of the plug 107.
  • a chamber 123 is again formed inside the second cylinder 124 and acts as seat for the hermetic sliding of the head 125 of the piston 126, the stem 127 whereof is connected to a first wing 129 of a lever 130 which is substantially V-shaped and is pivoted, approximately at the intersection between the first wing 129 and a second wing 131, to a pivot 132 that is rigidly coupled to the body 102.
  • the second wing 131 lies below the stem 106 of the plug 107, or is directly connected to it, so as to allow to easily open and close the plug 107 like the previous embodiment.
