Definitions

  • the present invention refers to an innovative device for blocking the shutter of a fixture, in particular a hinged shutter, which is rotatable around a vertical axis.
  • These blocking devices can comprise an arm made from steel, at one end hinged to an anchor block that can be fixed to the framework of the fixture, and at the other end hinged to a shoe which is able to slide along a rail formed on a profile of the shutter.
  • the sliding shoe has suitable blocking means, like a locking pin or a friction element, which are manually actuated by the user of the window to block the shutter in a desired position.
  • such a device is particularly expensive, due to the high consumption of material necessary to manufacture the arm with a certain length.
  • the general purpose of the present invention is to avoid the aforementioned drawbacks by making a blocking device for shutters of a fixture which allows the shutter to be fixed in any open position, even near to a complete 180° open position.
  • Another purpose of the invention is that of making a closing device which has a limited bulk.
  • Another purpose of the invention is that of making a device for blocking the shutter which has a limited impact on the aesthetics of the fixture also when the shutter is open.
  • Another purpose of the invention is that of making a blocking device which does not hinder the user when the shutter is open.
  • Another purpose of the invention is that of making a blocking device which is cost-effective and which has a simple structure.
  • a device for blocking a shutter of a fixture, rotatable around a vertical axis comprising a shoe intended to be mounted in a sliding manner along a rail of a horizontal profile of the shutter and an arm hinged against said shoe on one side and provided with constrainment means on the other, so as to be hinged in a rotating manner with respect to a fixed framework of the fixture, characterized in that said arm is intended to be hinged with respect to the framework at an axis for hinging the shutter against said framework, the arm having such a length that the hinging between the arm and the shoe, in use, projects from said rail of the shutter during its opening movement, the shoe having a longitudinal extension sufficient to remain engaged in the rail when the hinging between shoe and arm is outside of said rail, means for blocking the sliding of the shoe along the shutter of the fixture being present and thus fixing the shutter at a preset position.
  • figures 1 and 2 show a device 11 for blocking the shutter of a fixture and part of the fixture to which the device is applied.
  • the fixture for example, a window made from aluminium, comprises a framework 25 to be fixed onto a wall, onto which a shutter 24 is hinged with vertical axis hinging 31 (see figure 2 ).
  • the shutter comprises a vertical profile 26 that is hinged to the vertical profile 28 of the framework 25.
  • the device for blocking the shutter 11, clearly shown in figure 1 is mounted between the two horizontal profiles 27 and 29, of the shutter 24 and of the framework 25, respectively.
  • the blocking device 11 comprises an arm 13 hinged to an end with a shoe 12, through the hinging 21.
  • the arm is intended to be constrained through hinging to a horizontal profile of the framework, in the example in the figure, to the lower profile 29 of the framework 25.
  • the shoe 12 is intended to be fitted in a rail formed on a horizontal profile of the shutter 24, preferably the lower profile 27 of the shutter.
  • the shoe 12 can slide inside the rail, indicated with reference numeral 60 in figures 7 to 10 .
  • the arm 13 has constrainment means to be hinged to the profile 29 of the framework.
  • the constrainment means comprise a shaft-shaped body 14, able to be fixed in a rail 30 formed on the profile 29 of the framework.
  • the arm 13 is hinged through the hinging 15 to the shaft 14, which has suitable holes 16, 17 for fixing it to the profile 29 of the framework, for example, through screws.
  • the hingings 21 and 15 have vertical axes, similarly to the hinging 31 between shutter and framework.
  • shaft 14 can be fixed to the framework by using any prior art of the field, such as eccentrics, suitable for being blocked through rotation in the undercuts formed by the rail 30, or other equivalent techniques.
  • Figure 4 shows a section of the shaft 14 constrained in the rail 30 formed on the framework 25.
  • the shoe 12 has longitudinal ribbings 22 and 23 on opposite sides, intended to be engaged in undercuts formed by the side walls 32 and 33 which form the rail for the sliding of the shoe.
  • the section view of figure 3 clearly shows the walls 32, 33, which are normally present on the aluminium profiles of the fixtures, which form the rail with undercuts.
  • the shoe can come out from the rail only by slipping out from its open end.
  • the hinging 21, in an embodiment of the invention, is arranged at the ends of the shoe 12 and of the arm 13, respectively.
  • the arm 13 is intended to be mounted with the hinging 15 close to the axis of the hinging 31, and has such a length that the hinging 21 comes out from the rail formed along the lower profile of the shutter 24, during the opening movement of the fixture.
  • the shoe 12 has such a length that it remains engaged in the rail of the lower profile 27 of the shutter even when the hinging 21 has come out from the rail.
  • this particular characteristic of the closing device allows the shutter to be blocked in any open position, even in positions near to a rotation of 180° of the shutter with respect to the framework.
  • the blocking device 11 comprises means for blocking the sliding of the shoe 12 with respect to the shutter, with the purpose of fixing the shutter into a desired position.
  • the means for blocking the shoe 12 comprise a ratchet 18, intended to be slidably mounted along the vertical profile 26 of the shutter near to the corner of the shutter.
  • the ratchet 18 has a lower projection 20 suitable for being engaged in corresponding holes 19 formed in the shoe 12, as clearly shown in figure 1 .
  • the shoe 12 has an elongated shape and it can have, for example, six holes 19, corresponding to six open positions of the shutter. It should be understood that even a greater number of holes can be foreseen, according to the requirements.
  • the ratchet 18 is mobile between a retracted position from the shoe 12 and an engaged position for blocking its sliding with respect to the shutter 24.
  • the ratchet is raised so as to allow the shutter to be moved to a desired open position.
  • the ratchet can be provided with a suitable protrusion so as to facilitate its manoeuvring by the user.
  • the ratchet could be a spring ratchet with a chamfered tip so as to allow it to disengage from the holes 19 in the case of a force of a certain intensity applied to the shutter, so as to stop the structure from being damaged.
  • the ratchet can be controlled at a distance through a suitably long shaft mounted along the vertical profile of the shutter 24.
  • Figure 5 shows an alternative embodiment of the means for blocking the sliding of the shoe with respect to the profile 27 of the shutter. It should be considered that the blocking device is made in a totally analogous way as that previously described except for the blocking means of the shoe represented in fig. 5 .
  • the shoe 112 of the device comprises a threaded hole inside of which a screw 142 is engaged, able to be manoeuvred through the knurled handle 140 by the user of the fixture.
  • a friction element 141 suitable for going into abutment against the walls 32, 33 that define the sliding rail of the shoe, is arranged between the handle 140 and the profile 27 of the shutter.
  • the clamping screw can be replaced by a suitable eccentric of the prior art.
  • This particular arrangement allows the shutter to be blocked in any position, and not in a limited number of discrete positions like in the first embodiment. Moreover, there is the advantage of preventing damage to the structure in the case in which there is a very strong force against the shutter, since the friction can allow a certain sliding in the case of high intensity forces.
  • Figure 6 shows a further alternative embodiment of the means for blocking the sliding of the shoe 212. Also in this case, it should be understood that all the parts of the device that are not shown are similar to those described previously for the first preferred embodiment of the invention.
  • a screw 242 is received in a through-hole present in the arm 213 and in a corresponding threaded hole present in the shoe 212. Between the arm 213 and the shoe 212 there is a friction disc 241.
  • the screw 242 can be manoeuvred through the handle 240, to which it is fixedly connected.
  • the friction disc 241 When rotating the handle, the friction disc 241 is clamped between the arm and the shoe, so that the angular position between the two pieces is fixed and thus the sliding of the shoe along the profile of the shutter is also blocked.
  • the clamping action could also be carried out through an eccentric system, made per se according to the prior art.
  • Figures 7 to 10 show four positions in sequence that show the shutter being opened and the positions taken up by the blocking device.
  • FIG. 7 shows the first rotation step to open the shutter.
  • the shutter 27 rotates in the initial portion with the same direction as that of the rotation of the arm 13 of the blocking device.
  • the hinging 21 is again inside the rail 60 formed along the lower profile 27 of the shutter.
  • Figure 8 shows a subsequent position in which the shutter is rotated by almost 90° degrees with respect to the closed position.
  • the hinging 21 is at the open end of the rail 60 near to the hinging 31.
  • the arm 13 does not interfere with the framework of the fixture, in particular with the vertical profile 28 (shown in figure 2 ).
  • the hinging 21 thus disengages from the rail 60 before the arm 13 can interfere with the framework. This allows the shutter to rotate freely until it is complete open, as shown in figure 10 where the shutter manages to open even beyond 180°.
  • Figure 9 shows an intermediate position with the shutter open by about 145°.
  • the length of the arm is less than twice the thickness of the fixture, i.e., in a direction that is perpendicular to the plane of the framework.
  • the installer of the blocking device selects the position of the hinging 15 of the arm near to the hinging 31 of the shutter against the framework, so that the circumference described by the open end of the rail 60 is intersected by the circumference described by the possible rotation of the hinging 21.
  • the intersection between the two circumferences happens in a point which corresponds to a position of the arm which does not interfere with the framework of the fixture.
  • a device for blocking the shutter has been made, which allows the shutter to be fixed in angular positions even close to the complete 180° open position.
  • the blocking device is not very bulky, since the length of the arm is relatively limited compared to the dimensions of the fixture. This allows production costs of the material to be reduced, as well as, allowing any hindrance of the user of the fixture to be limited, since the device remains positioned in a circumscribed manner near to a corner of the framework.
  • the blocking device could be applied to the upper part of the fixture, and not to the lower part as described previously.
  • the fixing of the fixed shaft 14 can be possibly carried out by using suitable thicknesses, so as to be able to adjust the height of the hinging point of the rotatable arm 13 of the device in a suitable manner according to the requirements.
  • the device can be used having the function to stop the shutter in pre-established opening points by merely positioning some blocks against the sliding of the shoe in the rail, according to a known system.
  • a sliding rail for the shoe can be foreseen to be applied at the edge of the mobile shutter of the fixture, equipped with suitable undercut guiding ribbings.
  • the sliding rail can be applied to the profile of the shutter with any prior art, for example, through screwing.
  • the shoe that is able to slide in the rail of the shutter is not hinged at one of its ends to the rotatable arm, as described previously, but it could extend in length even beyond the hinging point (indicated with reference numeral 21 in the figures).
  • the system according to the invention is advantageously mounted "externally" on the sill or on the upper crossmember of the shutter. This allows the shutter block to be manoeuvred, to stop the shutter at any open angle, by manually acting upon it. This is the case both for the latch variant, and for the blocking variants on the sliding guide or on the joints.
  • the device has the possibility of being installed directly applied onto pre-existing shutters (doors, windows, jalousie windows, etc.), in their current state, possibly only adding the sliding rail if the shutter does not have one.
  • the device according to the invention makes it possible to position the fixed hinging point of the rotating arm on the lower or upper horizontal framework, with the possibility of spacing such a point away from the hinge of the shutter.
  • This characteristic apart from playing an important part in the dynamics of the forces involved (the closer to the main hinging point, the greater the lever effect and, thus, the tensions involved with safety problems), it also affects the manoeuvrability and the extent to which the shutter opens.
