| (54) | LOCK DEVICE FOR OPENING SLIDING WINDOWS |
| (57) The invention relates to a device used in sliding windows (3) that comprise at least
two sliding frames (31, 32) having mutual relative movement when opening the sliding
window (3). The device comprises: a first part (1) having a substantially annular
geometry; and a second part (2) designed to be inserted into the annular space of
the first part (1), at least one of the parts (1, 2) magnetically attracting the other.
The first part (1) is disposed on a frame (31) of the sliding window (3) in a position
interposed in the path resulting from the relative movement of the frames (31, 32)
when the sliding window (3) is opened, the position of the first part (1) also being
compatible with the relative movement of the frames (31, 32). The device allows the
desired width to be locked and delimited when opening a sliding window. |
OBJECT OF THE INVENTION
[0001] The object of the present patent application is to register a lock device for opening sliding windows which incorporates notable innovations and advantages over the techniques used hitherto.
[0002] More specifically, the invention proposes the development of a lock device for opening sliding windows which, due to the particular arrangement thereof, allows the desired width to be locked and delimited when opening a sliding window.
BACKGROUND OF THE INVENTION
[0003] Windows that open by sliding, provided with frames arranged so as to allow for a relative movement and superposition between the same, enabling an easy opening and closing thereof through manual actuation, are known in the state of the art.
[0004] In spite of the advantages of said windows in their use, it is not possible to mark and delimit the degree of opening desired in the manual actuation thereof.
[0005] The present invention contributes to solving and overcoming the present problem, which is to lock and delimit the desired width when opening a sliding window.
DESCRIPTION OF THE INVENTION
[0006] The present invention has been developed with the aim of providing a lock device for opening sliding windows, the sliding window comprising at least two sliding frames having mutual relative movement when opening the sliding window, characterized in that it comprises a first part having a substantially annular geometry and a second part designed to be inserted into the annular space of the first part, at least one of the parts magnetically attracting the other. The first part is disposed on a frame of the sliding window in a position interposed in the path resulting from the relative movement of the frames when the sliding window is opened, the position of the first part also being compatible with the relative movement of the frames.
[0007] In the lock device for opening sliding windows, the first part preferably has a substantially cylindrical geometry.
[0008] In the lock device for opening sliding windows, the second part preferably has a substantially cylindrical geometry.
[0009] Additionally, in the lock device for opening sliding windows, in the arrangement resulting from inserting the second part into the first part, the two parts have a coinciding axial axis.
[0010] Alternatively, in the lock device for opening sliding windows, the second part is fixed to another one of the frames of the same sliding window such that after moving along the path resulting from the relative movement of the frames when the sliding window is opened, the second part is superposed over the first part.
[0012] Alternatively, in the lock device for opening sliding windows, the second part is magnetized.
[0013] Alternatively, in the lock device for opening sliding windows, the first part is on the inside of the frame, and designed for the insertion of the second part.
[0014] The present invention achieves the aim of locking and delimiting the desired width when opening a sliding window.
[0015] Other characteristics and advantages of the lock device for opening sliding windows will become clear in light of the description of a preferred, though non-exclusive, embodiment, which, by way of a non-limiting example, is illustrated in the accompanying drawings, wherein:

DESCRIPTION OF A PREFERRED EMBODIMENT
[0017] As schematically shown in figure 1, the lock device for opening sliding windows of the present invention comprises a first part 1 having an annular geometry and a second part 2 designed to be inserted into the annular space of the first part 1.
[0018] In this preferred embodiment, schematically shown in figure 1, the two parts 1, 2 have a cylindrical geometry, with the axial axes thereof coinciding by the fact that the second part 2 is inserted into the first part 1.
[0019] As schematically shown in figure 2, the sliding window 3 in which the lock device for opening sliding windows of the present invention is used has sliding frames 31, 32 having mutual relative movement when opening the sliding window 3, said movement shown by the arrow in figure 2 and in a way that is already known in the state of the art.
[0020] In the detailed enlargement of figure 2, it can be seen how the first part 1 is arranged on the sliding window 3. Specifically, the first part 1 is fixed to one of the frames 31, and located in a way so that although it is interposed in the path of the relative movement of said frames 31, 32, it allows for the relative linear movement of the same, as represented by the arrow.
[0021] In this preferred embodiment, the second part 2 is magnetized and magnetically attracts the first part 1. In other preferred embodiments, it could be the first part 1 that is magnetized and which magnetically attracts the second part 2.
[0022] As schematically shown in figure 3 and in the detailed enlargement thereof, by inserting the second part 2 into the first part 1, ensuring said insertion thanks to the mutual magnetization between the two, the second part 2 impedes the relative movement of the frames 31, 32 as shown by the arrows due to the interposition thereof, thereby limiting the useful width of the opening 33 of the sliding window 3. Such limitation in said relative movement between the frames 31, 32 is something that was not possible with only the presence of the first part 1.
[0023] The different position of the first part 1 in one of the frames 31 of the window 3 will therefore be that which will limit the movement of the other frame 32 by the insertion of the second part 2, which in turn will delimit the degree of useful opening 33 of the sliding window 3.
[0024] In other preferred embodiments, such as the one schematically shown in figure 4 and in the detailed enlargement thereof, the second part 2 can be fixed to the frame 32 of the sliding window 3, for example, by means of screw elements, and hence joined to the frame 32 itself.
[0025] In the same way as it was previously explained, in the opening movement of the sliding window 3, the part 2 moves over the frame 31 on which the first part 1 is placed, following the movement of the frame 32 on which it is fixed, as indicated by the arrows in figure 4.
[0026] As schematically shown in figure 5 and in the detailed enlargement thereof, since the second part 2 is located over the first part 1, thanks to the mutual magnetization between them the second part 2 remains inserted in the first part 1, and therefore the frame 32 cannot continue to move along the path indicated by the arrows, thereby limiting the degree of useful opening 33 of the sliding window 3.
[0027] In other preferred embodiments, such as the one schematically shown in figure 6, the first part 1 can be arranged on the inside of the frame 31 and be invisible, which is why it is represented by dashes in the detailed enlargement in figure 6. In such case, the first part 1 is disposed and designed for the insertion of the second part 2 by means of a hole on the frame 31 itself. The functioning is similar to that described in previous cases.
[0028] The details, shapes, dimensions and other accessory elements, as well as the materials used to manufacture the lock device for opening sliding windows of the invention, may be suitably substituted for others which are technically equivalent, and do not diverge from the essential nature of the invention, nor the scope defined by the claims included below.
