Description

Device for closing doors and windows Sliding

Object of the invention

The present invention relates to a device for closing sliding doors and windows of the kind that glide over a set of guides.

The closing device object of the invention It is specially designed to block the door or window in its closing position and release its opening in a comfortable and simple.

Background of the invention

Generally closing devices for sliding doors and windows are composed of a housing provided with a push button and a closing hook, which is mounted on a recess made on the amount of the door or window, in correspondence with a counter hook mounted on the frame. He against hook is fixedly mounted on the frame and the closure hook has the power to scroll vertically to crimp and tear off the counter hook, to free the Door or window and allow opening and closing.

The closing hook moves between two extreme positions, one lock and one release, actuated by the user through the solidarity button on the closing hook. To open the door, the user must move down the button to release the hook of the counter hook. Once the hook is released, the blade can now be moved of the door or window to open and release the button, which, thanks to the arrangement of an internal spring returns to its resting position just like the hook.

To close the door or window again, the user must move the sheet against the frame, and press to overcome the force of the internal spring in order to re-engage the hook over the hook frame hook.

This closing operation is a bit complicated since sufficient force must be exerted to overcome  the inner spring and move down to the hook and to button, with all the frictions and frictions that oppose your glide.

Description of the invention

The device for closing doors and sliding windows that the invention proposes, resolves the problem discussed above, by locking and unlocking the opening and closing the sliding leaf in a comfortable and simple, without the need for excessive efforts.

To do this, and more specifically, the device for closing doors and windows is composed of  a housing provided with a push button and a closing hook that it hooks on a hook against the frame, whose hook is closure is mounted on a support that slides between two extreme positions assisted by a compressed spring between a top stop and the hook holder itself, having been planned that said support is connected to the push button through a projection  that moves between two positions on a groove practiced on the hook holder. In this way, when you have to close the sliding door or window, you just have to exert the force  necessary to move the support of the closing hook, without need to move the button thanks to the layout of the groove.

The support has a captive screw for the regulation and fixing of the closing hook, to which access through a hole made in the button, in correspondence with the prisoner, to enter the key of squeeze the prisoner, with the provision of a practicable trim to cover said hole.

The lower end of the button has a flexible connecting pin to keep the button flush with the surface of the housing, while at rest.

Description of the drawings

To complete the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings in which with illustrative and non-limiting nature, what has been represented next:

Figure 1 shows an elevation of a window of sliding sheets with the closure object of the invention.

Figure 2 shows a detailed view of the Figure 1 in which the arrangement of the hook can be seen and against hook.

Figure 3 shows an exploding perspective of the closure in which you can see all the elements that make up.

Figure 4 shows a longitudinal section of the  closing in closed position.

Preferred Embodiment of the Invention

In view of the figures outlined, you can be observed as the device for closing doors and windows It is constituted by a housing (1), designed to fit into the embedded in the amount (2) of the door or window (3). Said housing (1) has a properly sized opening to access the button (4) with your finger and unlock the closing.

The button (4) moves guided by the inside the housing (1) between two extreme positions, one of lock and other release.

The longitudinal movement of the button (4) it is assisted by an upper spring (15), which rests on the stop fixed top (16), and that keeps it in an expanded position while at rest. In this way, the user stops actuate the closure should insert your finger into the opening of the housing (1) and move down to the button (4), overcoming the upper spring force (15). In the present example of embodiment, the push button (4) is supported inferiorly on a base piece (7) by means of a flexible connecting pin (8) that allows keeping the outer surface of the button flush (4) with the housing surface (1). At the moment the user release the button (4), thanks to the spring arrangement upper (15), it returns to its resting position automatically.

To facilitate the placement of the device closing in the recess made in the amount (2) of the door or window, the lower part of the housing (1) has a pin slide (6) assisted by a spring (5) that keeps it expanded, for fixing on the recessed.

The upper part of the button (4) is connected to the closing hook (9), which crimps against it hook (10) arranged on the window frame (11). The connection between the upper part of the button (4) and the hook (10) it is done through a support piece (12) empowered to slide between two extreme positions with respect to the button (4). The button (4) is linked to the support (12) through a projection (13) that penetrates and travels longitudinally along the inside a groove (14) made on the support (12) of the hook. Said support (12) is also assisted by the spring upper (15), which is housed between the upper stop (16) and the support itself (12). Thanks to the provision of upper spring (15) and stop (16), the support (12) and therefore the hook (9), always remain in the expansion position ascending, regardless of the position of the button (4).

Thanks to the slot arrangement (14), the button (4) and the support (12) of the closing hook (9) will have a relative displacement between them, limited by the length of the own slot (14). Thus, when we scroll down to the button (4), it will drag through the bottom stop of the slot (14), to the support (12) causing the release or release of the hook (9) of the counter hook (10), allowing the opening of the window (3). Once the window is opened, the user can release the button (4), returning it to its resting position. At  same time, the support (12), thanks to the arrangement of the upper spring (15), will return to its resting position.

When the user wants to close the window, you must move it towards the frame (11), and press so that the hook (9) moves longitudinally when contacting the counter hook (10), thanks to its design. Longitudinal displacement descending the hook (9) will result in the displacement of its support (12), but not the movement of the button (4) thanks to the arrangement of the groove (14) that allows this movement relative. By not having to move the button (4), it will not be it is necessary to exert so much force, so the closure will be smoother and confortable.

To adjust and fix the closing hook (9) on the support (12) there is a captive screw (17) which sets it in the correct adjustment position. To access the captive screw (17) with the corresponding key, the push button (4) is provided with a hole (18), in correspondence with said captive screw (17).

Finally, the button (4) has a practicable trim (19) covering said hole (18).
