Description
- The present invention relates to a rod handle for fixtures, in particular for windows.
- As is known, a rod handle is a device attached to a fixture in order to operate movement rods of a closing system of the fixture. The movement rods can be arranged on the outside of the structure of the fixture or can be housed inside said structure.
- In general, a rod handle comprises:
- a fixing base, which is intended to be rigidly fixed to the fixture structure;
- a gripping handle that is rotationally associated with the fixing base; and
- a mechanism that kinematically connects the gripping handle to the movement rods in order to convert a rotational movement of the gripping handle into a translational movement of these rods.
- More specifically, the kinematic connection mechanism between the gripping handle and movement rods comprises:
- a cogwheel, in which the axis of rotation is orthogonal to the fixing base of the handle; and
- a pair of operating rods, which mesh with the cogwheel in opposite positions in respective toothed portions and are intended to be connected to the above-mentioned movement rods.
- The cogwheel and the two operating rods form a rack-pinion system. A rotational movement of the cogwheel requires the two rods to move in parallel with the fixing base and with one another, in opposite directions.
- In turn, the cogwheel is rotationally integral to the gripping handle by means of a prismatic axial coupling. In terms of operation, a rotational movement of the gripping handle corresponds to a rotational movement of the cogwheel of the same angular width and therefore to a predefined translational movement stroke of the two operating rods.
- In order to ensure stable meshing between the cogwheel and operating rods and, at the same time, impose the required stroke on the two rods by means of a rotational movement of the gripping handle having an angular width that is operatively permissible for manual operation (between 90° and 180°), the cogwheel has to have a minimum nominal diameter. This imposes minimal dimensions in the transverse direction on the fixing base of the handle so as to be able to house the cogwheel and the two rods.
- The "transverse direction" means the plan dimension that is orthogonal to the longitudinal direction, in parallel with which the two rods move. This bond affects the dimensions of the profiles that form the frame of the fixture and those the handle has to be attached to by means of the relative fixing base.
- In the field of fixtures, for aesthetic reasons and in order to maximize the window region, there is the tendency to make fixtures comprising profiles having increasingly slim dimensions.
- There is therefore the need to provide rod handles that can be made having smaller transverse dimensions than the current dimensions so as to impose less stringent limitations on the dimensions of the profiles that can be used to make the fixtures, without imposing limitations on the longitudinal stroke of the rod and/or the rotational movement of the gripping handle.
- There is therefore the need to overcome the problems and limitations cited with reference to the prior art.
- This need is met by a rod handle for fixtures as per
claim 1. - Additional features and the advantages of the present invention will become clearer from the description given below of preferred non-limiting embodiments thereof, in which:

- With reference to the above-mentioned drawings, 1 indicates, as a whole, a rod handle for fixtures as per the present invention.
- The
handle 1 according to the invention is in particular intended to be attached to windows (sliding or casement windows), but can generally also be attached to other types of fixtures, for example door fixtures, French doors or front door fixtures. - The
rod handle 1 comprises afixing base 2 that is intended to be rigidly fixed to a fixture (not shown in the attached drawings). In particular, thefixing base 2 is intended to be fixed to a profiled portion that forms the frame of the window. - The
fixing base 2 extends in plan in a longitudinal direction X-X and in a transverse direction Y-Y, which is orthogonal to said longitudinal direction X-X. - "Plan extension" means the extension of the portion of the fixing base that is intended to rest against the fixture. The attachment of a
handle 1 to a fixture is influenced by the transverse dimensions of the fixing base, which may not be greater than those of the fixture portion intended to receive the handle. - In particular, as illustrated in the attached drawings, the
fixing base 2 can be made up of a plate, preferably in metal material. Thefixing base 2 can be provided with a plurality of through-holes for inserting anchoring elements into the fixture, for example screws or bolts. - In addition to the
fixing base 2, thehandle 1 comprises: - a
cogwheel 10, which is rotationally connected to thefixing base 2 so that the axis of rotation Z1-Z1 is orthogonal to said base; and - at least a
first operating rod 11, atoothed portion 11a of which meshes with thecogwheel 10 so as to form a rack-pinion system together with thecogwheel 10. - The
first operating rod 11 can move in a translational manner with respect to thefixing base 2 in parallel with said longitudinal direction X-X following rotational movements of thecogwheel 10 about its axis of rotation Z1-Z1. In terms of operation, thisfirst operating rod 11 is intended to be connected to a closing system of a fixture (not shown in the attached drawings) in order to operate it by means of its translational movements. - The
handle 1 also comprises agripping handle 20, which is rotationally moveable with respect to thefixing base 2 between a first angular position and a second angular position and is kinematically connected to thecogwheel 10 in order to drag thecogwheel 10 in rotation as it passes between said two angular positions. - In terms of operation, the rotational movement of the cogwheel causes the translational movement of the first movement rod between two different longitudinal positions, in which the closing system is operated such that it closes and opens, respectively.
- In accordance with one embodiment that is not shown in the attached drawings, the
handle 1 may comprise just one operating rod. In terms of operation, in this case, thehandle 1 can only act on the closing system of the fixture from one point only. - Preferably, as illustrated in the attached drawings, the
handle 1 comprises twooperating rods cogwheel 10. In other words, thehandle 1 comprises asecond operating rod 12 in addition to saidfirst operating rod 11. In terms of operation, in this case, thehandle 1 can act on the closing system of the fixture from two different points. - More specifically, a
toothed portion 12a of thissecond operating rod 12 meshes with thecogwheel 10 in a position that is transversally opposite thefirst rod 11. - This
second operating rod 11 is also: - movable in a translational manner with respect to the
fixing base 2 in parallel with the longitudinal direction X-X at the same time as saidfirst rod 11, but in the opposite direction thereto, following rotational movements of thecogwheel 10; and - intended to be connected to said fixture closing system - in a position that is longitudinally opposite said first rod 11 - in order to contribute to operating it by means of its translational movements.
- Said first and
second operating rods cogwheel 10. - As illustrated in the attached drawings, the
cogwheel 1 and the two operatingrods 11, 12t have overall transverse plan dimensions not greater than the transverse extension of the fixingbase 2. This is also applicable when thehandle 1 comprises a single operating rod. - Preferably, as illustrated in the attached drawings, each of said two operating
rods appendage cogwheel 10 is rotationally associated) and passes through thebase 2 via a respective through-hole for longitudinal sliding 3, 4. Each operatingrod respective appendage handle 1 comprises just one operating rod. - The
appendage Fig. 1 to 5 ) or of a plate (as illustrated inFig. 6 to 10 ). - Advantageously, in use these
appendages base 2, can enter the frame of the fixture in which thehandle 1 is attached and can therefore reach components of the closing system that are housed inside said frame. - According to the invention, the gripping
handle 20 is kinematically connected to thecogwheel 10 by means of a bevelgear transmission system - the driving
bevel wheel 31 of the bevel gear is rotationally integral with saidgripping handle 20 in order to be rotated by the rotational movements of the gripping handle between the above-mentioned first and second angular positions; and - the driven
bevel wheel 32 of the bevel gear is rotationally integral with thecogwheel 10. - The expression "rotationally integral" referring to the driving bevel wheel with respect to the gripping handle means that the driving bevel wheel integrally rotates with the gripping handle about the same axis of rotation.
- Similarly, the expression "rotationally integral" referring to the driven bevel wheel with respect to the cogwheel means that the driven bevel wheel integrally rotates with the cogwheel about the same axis of rotation.
- Preferably, as shown in the attached drawings, the driven
bevel wheel 32 is made as one piece together with thecogwheel 10. - The driving
bevel wheel 31 and the associated grippinghandle 20 are rotationally supported by acontainment structure 40, which is in turn fixed to the fixingbase 2. The drivenbevel wheel 31 is instead rotationally supported by thecogwheel 10 that, as already mentioned, is in turn directly rotationally supported by the fixing base. - According to the invention, the above-mentioned
bevel gear system gripping handle 20 between said first and second angular position it corresponds an angular rotation of thecogwheel 10 having a greater width. In other words, the drivingcogwheel 31 has a nominal diameter that is greater than the nominal diameter of the drivenwheel 32. - In this way, when dimensioning the
handle 1, it is possible to adapt the nominal diameter of thecogwheel 10 to a predefined transverse extension of the fixingbase 2 and to a predefined longitudinal stroke of said at least one operatingrod 11, without having to adjust the width of the angular stroke of thegripping handle 20 between said first and second angular position. - In other words, due to the use of the bevel gear transmission system described above, it is in particular possible to reduce the nominal diameter of the cogwheel 10 (and therefore to contain the transverse plan extension of the fixing base 2) without having to intervene with the width of the longitudinal stroke of the operating rod and/or with the width of the rotational movement of the gripping handle between the first and the second angular position. In fact, with the width of the angular rotation that can be imposed on the
gripping handle 20 by a user being set, the reduction in the nominal diameter of thecogwheel 10 does not influence the extension of the longitudinal stroke of the rod since this reduction is compensated for by an increase in the width of the angular rotation of saidcogwheel 10. - It should be noted that a reduction in the nominal diameter of the cogwheel corresponds to a reduction in the number of teeth in said wheel and not to a reduction in all the dimensions of said teeth. This means that the reduction in the dimensions of the cogwheel does not jeopardize the meshing stability between the cogwheel and the rod, to the advantage of robustness and reliability of the
handle 1. - Due to the invention, it is therefore possible to reduce the nominal diameter of the cogwheel without the handle losing functionality, and simultaneously ensuring stable meshing between the cogwheel and the operating rods.
- Advantageously, as shown in the attached drawings, the above-mentioned bevel
gear transmission system base 2 and thegripping handle 20 and extends together with the drivingbevel wheel 31 that substantially extends in the orthogonal and longitudinal direction with respect to thebase 2 so as not to increase the transverse plan dimensions of the handle and therefore of the fixing base. - In accordance with the embodiment illustrated in the attached drawings, the bevel
gear transmission system - the nominal diameter of the driven
bevel wheel 32 is not greater than the transverse extension of the fixingbase 2; - the angle between the axes of said bevel gear is 90°; and
- the driving
bevel wheel 31 is arranged such that its own axis of rotation Y1-Y1 is parallel to said transverse direction Y-Y. - The driving
bevel wheel 31 is therefore arranged such that the diametric dimensions thereof do not affect the dimensions in the transverse direction, but only the dimensions in the orthogonal and longitudinal directions. In the transverse direction, the dimensions of thedriving wheel 31 correspond to the height of the teeth thereof and therefore remain inside the transverse dimensions of the drivenwheel 32. - In this way, the bevel
gear transmission system base 2 and are not influenced by the nominal diameter of the drivingbevel wheel 31. - In particular, the two
conical wheels - Preferably, as illustrated in the attached drawings, the gripping
handle 20 is made up of a lever having a pivot and rotation axis that coincides with the axis of rotation Y1-Y1 of the drivingbevel wheel 31. Therefore, in the preferred case in which the drivingbevel wheel 31 is arranged so that its axis of rotation Y1-Y1 is parallel to said transverse direction Y-Y, the axis of rotation of thegripping handle 20 is also parallel to said transverse direction Y-Y. - Even more preferably, the gripping
handle 20 with lever has transverse dimensions that are no greater than the transverse extension of the fixingbase 2. - Preferably, this configuration of the
gripping handle 20 is provided in the preferred embodiment in which the bevel gear transmission system has transverse dimensions that are no greater than the transverse plan dimension of the fixingbase 2. In this way, in its entirety, thehandle 1, included then also thegripping handle 20, has transverse plan dimensions that are not greater than the transverse plan extension of the fixingbase 2. - In accordance with the embodiment illustrated in the attached drawings, the gripping
handle 20 comprises aportion 21 of pivoting thecontainment structure 40 and a grippingportion 22, which is fixed to the pivoting portion. Advantageously, as shown inFig. 5 , the grippingportion 22 is made separately from the pivotingportion 21 and its shape may differ depending on design requirements. - Preferably, as illustrated in the attached drawings, the driving
bevel wheel 31 is made in one piece with said pivotingportion 21 of thegripping handle 20. Alternatively, the drivingbevel wheel 31 can be made separately and can be made integral with the pivotingportion 21 of thegripping handle 20 by means of one or more pins. - In accordance with one embodiment illustrated in the attached drawings, the
containment structure 40 is defined by a box-shaped body having an internal portion that is equivalent to the plan shape of the fixingbase 2. Thecontainment structure 40 is fixed to the fixingbase 2 by means of shape coupling. - Preferably, as illustrated in the attached drawings, the above-mentioned
containment structure 40 is designed to delimit, together with the fixingbase 2, afirst chamber 5 in which thecogwheel 10 and the two operatingrods - The
containment structure 40 is also designed to delimit asecond chamber 6, which is orthogonally superposed on thefirst chamber 5 and in which the bevelgear transmission system - The
first chamber 5 and thesecond chamber 6 communicate with one another to allow for the kinematic coupling between thecogwheel 10 and the drivingbevel wheel 31. - The
gripping handle 20, preferably made up of a lever, is rotationally associated with saidcontainment structure 40 in thesecond chamber 6. More specifically, the pivotingportion 21 of thegripping handle 20 is housed in thesecond chamber 6, while the grippingportion 22 protrudes from thesecond chamber 6. - The invention makes it possible to achieve numerous advantages, some of which have already been described.
- The rod handle according to the invention can be made having smaller transverse dimensions with respect to those of known rod handles, without, however, losing functionality.

- The handle according to the invention can also be made having very limited transverse dimensions, thus combining reliability and robustness.
- The individual components that form the internal movement mechanism of the handle can in fact be made having reduced dimensions, without, however, losing rigidity.
- The invention designed in this way therefore achieves the predetermined objects.
- Of course, when practically implemented, said invention may also assume shapes and configurations that differ from that illustrated above, without thereby departing from the present scope of protection.
