| (54) | HANDLE FOR LARGE RAISABLE DOORS AND WINDOWS |
| (57) The invention relates to a handle for large raisable doors and windows, comprising
a lever (5) linked to a profile (2) of a door or window sash, with a cavity (6) spacious
enough to house all the necessary elements to transmit the rotational movement of
the lever to the transmission mechanism so that the rotational movement of the lever
is transformed into a translational movement of the mechanism arranged inside the
door or window sash for the release or fastening to the window frame. |
OBJECT OF THE INVENTION
[0001] The present invention relates to a handle for large raisable doors and windows intended to be installed on a wing of a door or window profile, the elements of which, responsible for transmitting the rotational movement of a lever to a transmission box housed in the profile, are housed in the body of the lever, such that the only element that remains visible to the user is the lever and, additionally, the elements that could make the operation of turning the handle uncomfortable are eliminated.
BACKGROUND OF THE INVENTION
[0002] Currently, manually actuated handles for transmitting rotational movement to the internal mechanisms of the system, being transmission boxes in the case of handles, or transmission covers in the case of espagnolettes, etc., are known.
[0003] The rotational movement transmitted by the handle is transformed into translational movement by mechanisms which can be both inside the profile in the form of a transmission box, and at the base of the handle in the form of an espagnolette, normally by means of rack and pinion systems.
[0004] However, currently known handles that do not have a base, such as invisible handles in which the user only sees the lever, are intended for use on windows or doors with standard applications. The object of the invention is the designation of a handle with a concealed mechanism for use in lift-and-slide windows.
DESCRIPTION OF THE INVENTION
[0005] The present invention relates to a handle for large raisable doors and windows, intended to be linked to a transmission mechanism arranged inside a profile, of a sash of a door or window, equipped with a wing, wherein the wing comprises an opening.
[0006] The handle comprises a lever intended to be arranged on the outside of the profile and which is provided with a cavity, from which a first through hole extends transversally, and with a rotating shaft provided with one end housed in the cavity and another end intended to pass through the opening and to couple to the transmission mechanism in an assembled condition.
[0007] The handle comprises a base intended to be linked to the wing from the outside of the profile and to be partially housed in the opening and in the cavity, which is provided with a through cavity, which houses the shaft in an assembled condition.
[0008] The handle comprises a transmission bushing open at both ends and which holds the shaft, rotating integrally with the same, wherein in an assembled condition one of the ends thereof is housed in the through cavity and the other end, which comprises a second through hole that extends transversely from the outer surface thereof, is housed in the cavity.
[0009] The handle comprises a casing that partially holds the transmission bushing and is linked to the base, retaining the transmission bushing in a direction longitudinal to the shaft and which is housed in the cavity once it has been linked to the base and the same has been joined to the wing.
[0010] Likewise, the handle comprises a retention element that can be housed in the through holes once the base has been joined to the wing, and tightened on the shaft, preventing the movement thereof in the longitudinal direction, linking the lever to the transmission bushing, such that the rotation of the lever causes rotation of the shaft.
[0011] In this way, once the handle has been installed on the window, only the lever is visible to the user, meaning the rest of the elements are concealed, remaining hidden within the lever itself. Thanks to the compact configuration of the handle, all the elements are configured to be hidden inside the lever. In addition to achieving a minimalist aesthetic, the elements that could make the manoeuvring operation uncomfortable for the user have been eliminated or hidden.
[0012] This handle is specifically designed for lift-and-slide systems, in which the levers are large, and thus the cavity to house the elements is spacious enough to house all the necessary elements to transmit the rotational movement of the levers to the transmission box.
[0013] The fastening of the lever with respect to the transmission bushing, and therefore to the rotating shaft, is carried out by means of the retention element, which is preferably a grub screw.
[0014] The transmission mechanism of the window, a transmission box for example, is responsible for transforming the rotational movement of the lever into a translational movement of an espagnolette arranged inside the door or window sash for releasing or fixing the same to the window frame.

PREFERRED EMBODIMENT OF THE INVENTION
[0016] Figure 1 shows a perspective view of a handle in an intermediate mounting condition on a window. The handle for large raisable doors and windows is linked by means of a rotating shaft (8) to a transmission mechanism (1), not visible, arranged inside a profile (2), of a sash of a window, like the one shown in the figure, which, in turn, is provided with a wing (3) comprising an opening (4).
[0017] It can be seen that the handle comprises a large lever (5) that is intended to be installed on the wing (3) from the outside of the profile (2) and that it is provided with a cavity (6) from which a first through hole (7) extends transversely, not shown in the figure.
[0018] The rotating shaft (8) is provided with one end housed in the cavity (6) and another end intended to pass through the opening (4) and to couple to the transmission mechanism (1) in an assembled condition, transmitting the rotational movement of the lever (5).
[0019] The handle comprises a base (9) that is linked to the wing (3) from the outside of the profile (2) and is intended to be partially housed in the opening (4) and later, once it has been linked to the wing (3) by means of first screws (27) and holes (28), is configured to be housed in the cavity (6) of the lever (5). The base (9) is also provided with a through cavity (10), not shown in the figure, which houses the shaft (8) in an assembled condition.
[0020] The handle has a transmission bushing (12) open at both ends which holds the shaft (8), rotating integrally with the same, wherein in an assembled condition one of the ends thereof is housed in the through cavity (10) of the base (9), not shown, and the other end, shown in the figure, which comprises a second through hole (13) that extends transversely from the outer surface thereof, is housed in the cavity (6) of the lever (5).
[0021] The handle comprises a casing (18) that partially holds the transmission bushing (12) and is linked to the base (9), retaining the transmission bushing (12) in the longitudinal direction of the shaft (8) and is housed in the cavity (6). In this way, the base (9) and the casing (18) are joined, retaining partially at least the transmission bushing (12) on the inside thereof, which in turn holds the shaft (8), wherein by linking the base (9) to the profile, all the elements are positioned, and by placing the lever (5), the same houses them in the cavity (6) thereof, wherein the attachment between the lever (5) and the transmission bushing is made by means of a retention element (16).
[0022] The retention element (16) can be housed in the through holes (7, 13), once the base (9) has been attached to the wing (3), and it is tightened on the shaft (8), preventing the movement thereof in the longitudinal direction and linking the lever (5) to the transmission bushing (12), such that the rotation of the lever (5) causes the rotation of the shaft (8).
[0023] Figure 2 shows a perspective view of a handle linked by means of the shaft (8) to a transmission mechanism (1), which is a transmission box responsible for transforming the rotational movement transmitted by the handle into translational movement.
[0024] Figure 3 shows a perspective view of an exploded view of a handle, according to the present invention, in which all the elements that make up the handle are shown.
[0025] The detailed view shows that the handle additionally comprises a positioning bushing (14) facing the base (9). The positioning bushing (14) is configured to hold the transmission bushing (12), such that they rotate together in an assembled condition.
[0026] It can be seen that the base (9) comprises projections (11) opposite the surface intended to be linked to the wing (3) and the positioning bushing (14) comprises recesses (15) opposite the projections (11), wherein the relative position of the projections (11) with respect to the recesses define the rotational positions of the lever (5). The two projections (11) are arranged at 0° and 180°, defining an open position and a closed position of the lever (5).
[0027] The handle is provided with an elastic element (17) configured to fit around the transmission bushing (12) that extends between the positioning bushing (14) and the casing (18) and decompresses when the projections (11) coincide with the recesses (15). The elastic element (17) allows the aforementioned elements to return to one of the relative positions and to remain in that position. The actuating force on the lever (5) must be able to overcome that of the elastic element (17), a spring, in order for the same to move and allow movement from one relative position to the other.
[0028] It can be seen that the second section (20) is provided with two longitudinal projections (22) and the positioning bushing (14) is provided with two slots (23) through which the positioning bushing (14) moves when alternating between the rotational positions of the lever (5).
[0029] The transmission bushing (12) is provided with a longitudinal cavity (26) complementary to the outer surface of the shaft (8) to improve the coupling between the two, which in this case is square.
[0030] Figure 4 shows a view of a longitudinal cross section of an exploded view of a handle, according to the present invention. The enlarged detail shows that the transmission bushing (12) is provided with three sections, a first section (19) configured to be housed in the through cavity (10) of the base (9), a second section (20) that extends from the first section (19) and has a larger cross section than the through cavity (10), and a third section (21) that extends from the second section (20) and has a smaller cross section than the same, where the second through hole (13) is arranged.
[0031] It should be noted that the cavity (6) of the lever (5) is provided with a first chamber (24) and a second chamber (25) that extends from the first chamber (24) and is narrower than the same, wherein the second chamber (25) is complementary to the third section (21) of the transmission bushing (12) and the first hole (7) extends from this chamber.
[0032] Likewise, it can be seen that, in the area intended to remain outside the profile (2), the base (9) comprises base holes (31) that are coaxial to casing (18) holes (30) in such a way that, in an assembled condition, the connection between the casing (18) and the base (9) is made by means of second screws (29) that are housed in the base holes (31) and the casing holes (30).
[0033] In this way, the casing (18) can be previously assembled on the base (9), with the positioning bushing (14), the elastic element (17) and the transmission bushing (12) and later this assembly can be placed on the wing (3) and be joined to the same by means of the first screws (27), to later place the shaft (8), the lever (5) and, lastly, the retention element (16).
[0034] Figure 5 shows a longitudinal cross-sectional view of a handle, wherein all the elements are shown in an assembled condition.
[0035] Figure 6 shows a perspective view of two handles according to the present invention, wherein it can be seen that by merely duplicating the elements and linking the shafts (8), so that they are coaxial or form a single shaft, it is possible to obtain a double handle, if so desired, such as to have a lever (5) outside and inside a room, without affecting the operation of the handle.
