Description

The present invention relates to a cremone handle for window units, in particular for window units that are outward opening or form curtain walls.
The window units, whether metal or synthetic, forming outward opening or curtain wall windows comprise a traditional fixed frame and a mobile sash with vertical members and horizontal members, but, unlike a traditional side-hung window, the sash is pivoted, that is to say, it opens and closes by rotating about an upper horizontal member or about an axis parallel with it, or using a system of levers hinged between the fixed frame and the sash in such a way as to allow pivot opening, or a complete sash movement forward and backward, that is to say, parallel with the fixed frame.
This configuration of the sash movement system causes some variations both in the window hardware and in the assembly and positioning of the accessories used to move the sash.
As illustrated in Figure 1 (an exploded view of part of the movement units on one of these types of known window sashes), part of the sash contact and closing elements 12 are located at the lower horizontal member, where the sash movement handle unit M is also fitted, whilst another part of the elements is located on the two vertical members.
This different positioning of the contact and closing elements means that the handle unit M is also in a different position (again see Figure 1), mounted on the surface of the horizontal member forming the wall of the tubular chamber of the section bar which forms the sash.
If the handle unit M were the traditional handle body with a grip attached to it and a centred axis of rotation, see Figure 1, it would be difficult to move the grip IM, since the handle is mounted close to the glazing and, therefore, the space allowing access for the user's hand on the grip IM in that position would be at a minimum to allow grip rotation with the axis of rotation Z parallel with the extension of the glazing.
This problem is currently solved using an off centre grip, shaped so that it moves away from the window sash, increasing the distance between the grip and the glazing.
Said solution, on one hand, solving the problem of grasping the grip, on the other hand made it more necessary to always allow for the possibility of fitting a grip shaped to the right or left on the handle body depending on operating or aesthetic requirements of the window unit, with obvious negative effects on the stocking of such handle parts.
This disadvantage arises as a result of the fact that the particular shape of the off centre grip and the fact that it is made in a single special block for application on the handle body does not allow any type of reversibility when it is assembled on the handle body.
The aim of the present invention is, therefore, to overcome these disadvantages by providing a cremone handle for window units, in particular for window units which open outwards or form curtain walls which is extremely practical, easy to use and allows the grip to be reversed.
Accordingly, this aim is achieved by a cremone handle for window units, in particular for outward opening window units comprising a fixed frame and a mobile sash consisting of two vertical members and two horizontal members connected to the fixed frame in such a way as to allow at least part of the sash to move away from and towards the fixed frame so as to form respective sash opening and closing configurations. A handle unit is attached to the lower horizontal member of the sash, the handle unit being designed to allow sash opening and closing. The handle unit comprises at least: a handle body which can be attached to the lower horizontal member of the sash, a movement grip projecting from one side of the handle body and able to rotate about an axis of movement, control parts projecting from the opposite side of the handle body to the grip, and able to connect to movement devices for the sash closing and opening configurations. The handle unit also comprises an angled connecting element, inserted between the handle body and the grip, which can be connected on one side to the control parts, through the handle body, and on the other side is fitted with means for a removable connection to the grip, applicable reversibly, that is to say, on the right or on the left of the handle body, to the connecting element and able to rotate with said element about the axis of movement.
The technical features of the present invention, in accordance with the above aims, are apparent in the claims herein, and the advantages are more clearly described in the detailed description below, with reference to the accompanying drawings, which illustrate a preferred embodiment of the invention, without limiting the scope of its application, and in which:

Figure 1 is a schematic perspective view with some parts cut away to better illustrate others of an outward opening or curtain wall window unit and a relative cremone handle of the known type;
Figure 2 is a schematic perspective view with some parts cut away to better illustrate others of the window unit illustrated in Figure 1, to which a cremone handle made in accordance with the present invention is applied;
Figure 3 is a schematic front view of the window unit illustrated in Figure 2;
Figure 4 is a partially exploded perspective view of the cremone handle made in accordance with the present invention;
Figure 5 is a perspective partial view of a detail of the handle grip illustrated in Figure 4 ;
Figures 6 and 7 are respectively a top plan view and a partial cross-section through line VII - VII in Figure 6 of an alternative embodiment of the cremone handle illustrated in the previous figures. With reference to the accompanying drawings, and in particular with reference to Figures 1 and 2, the cremone handle disclosed, labelled 100 as a whole, can be used on outward opening or curtain wall window units comprising at least a fixed frame 1 and a mobile sash 2 consisting of two vertical members 3 and 4 and two horizontal members 5 and 6 and attached to the fixed frame 1 in such a way as to allow at least part of the sash 2 to move away from and towards the fixed frame 1 so as to form respective window opening and closing configurations.

The sash 2 connection can be created using connecting means 7 which may be, by way of example, known hinges applied parallel with or at the upper horizontal member 6, or systems of levers which are hinged and connected to the fixed frame 1 and sash 2 to allow pivot opening of the sash 2 or complete movements of the sash 2 relative to the fixed frame 1.
A handle unit 8 is attached to the lower horizontal member 5 of the sash 2. The handle unit is designed to allow opening and, respectively, closing, of the sash 2 (see arrows F in Figures 1 and 2).
This handle unit 8 comprises at least:

a handle body 9 which can be attached to the lower horizontal member 5 of the sash 2;
a movement grip 10 projecting from one side of the handle body 9 and able to rotate about an axis of movement Z;
control parts 11, projecting from the opposite side of the handle body 9 to the grip 10, and which can be connected to movement devices 12 for forming the above-mentioned sash 2 closing and opening configurations (these devices are schematically illustrated in Figures 1 and 2 since they are of the known type).

As shown in Figure 2, the control parts 11 comprise a pair of bars 11a and 11b which can be operated by the grip 10 by means of elements inside the handle body 9, of the known type and not illustrated here. As illustrated in Figures 3 and 4, the handle 100 comprises an angled connecting element 13, inserted between the handle body 9 and a grip 10, and which can be connected on one side to the control parts 11, through the handle body 9 and on the other side has means 14 for a removable connection to the grip 10 applicable reversibly, that is to say to the right or left of the handle body 9 depending on sash operating requirements, to the connecting element 13 and able to rotate with said element 13 about the axis of movement Z.
More precisely, the angled connecting element 13 has the shape of an inverted "L" on one side and, on its end surface 13a, has a seat 15 for stably housing a control shaft 11c, which is one of the control parts 11, rotatably housed in the handle body 9, whilst on the other end surface 13b, the element 13 has means 14 for a removable connection to the grip 10.
In practice, on the end surface 13b, the element 13 has a projecting pin 16, forming the connecting means 14, which can be connected in a corresponding seat 17 in the portion of the grip 10 which faces the end surface 13b so as to render the angled connecting element 13 integral with the grip 10.
As illustrated in Figure 5, on the grip 10 there may be means 18 for removably securing the grip 10 on the angled connecting element 13. The means 18 may be located on the grip 10 and act on the pin 16 housed in the seat 17 in the grip 10.
These securing means 18 may comprise a threaded grub screw 18g which can be screwed into a through-seat 19 in the grip 10 and in such a way that it transversally intercepts the pin 16 housed in the seat 17 of the grip 10.
As illustrated again in Figure 4, the handle 100 axis of movement Z extends vertically, whilst the angular connecting element 13 forms a grip 10 axis of motion X perpendicular to the axis of movement Z and such that the grip 10 and the angled connecting element 13 rotate in a substantially horizontal plane (see arrows F1).
As illustrated in Figures 6 and 7, another way of accessorizing the handle 100 disclosed may be to insert a safety lock with a key.
To do this, on the connecting element 13 there are parts 20 for locking and releasing the handle 100 rotation, extending along an axis Z' parallel with the axis of movement Z and close to the control shaft 11c.
These locking and release parts 20 operate between the connecting element 13 and the handle body 9 to allow rotation of the connecting element 13 and the grip 10 relative to the handle body 9 to be stopped.
By way of example, without in any way limiting the scope of the invention disclosed, the locking and release parts 20 (see Figure 7) may comprise a key cylinder 21 housed in a relative seat 22 in the connecting element 13.
The upper end of the cylinder 21 is located, in view, at an upper surface 13c of the connecting element 13, whilst the lower end of the cylinder has a pin 23 which is vertically mobile between a first, release operating position (illustrated with a dashed line in Figure 7), in which the pin 23 is completely housed inside the connecting element 13 and allows free rotation of the connecting element 13 with the grip 10, and a second, locked forward operating position (illustrated with a continuous line in Figure 7), in which the pin 23 projects and is housed in a seat 24 in the handle body 9 so as to stop the rotation of the connecting element 13 and the grip 10 relative to the handle body 9.
Moreover, the handle body 9, may have two seats 24 diametrically opposed so that the handle 100 can be fitted with the grip 10 to the left or the right without having to change the position of the locking and release parts 20.
Therefore, a handle structured in this way achieves the preset aims thanks to a simple structure, but with the possibility of reversible fitting of the grip, according to the operating or aesthetic requirements of the window fitted.
This reversible fitting is made simple and fast thanks to the presence of two separate elements which, in practice, form the grip, and thanks to the connection of the pin with the threaded grub screw, allowing rapid and easy grip positioning and securing on the left or the right, whichever is most suitable.
The invention described is suitable for obvious industrial applications and may be subject to modifications and variations without thereby departing from the scope of the inventive concept. Moreover, all of the details of the invention may be substituted by technically equivalent elements.
