| (54) | AN INTEGRATED FRAMEWORK FOR A BRAKING DEVICE FOR DOOR PANELS OF SLIDING DOORS |
| (57) An integrated framework for a braking device for door panels of sliding doors comprises
a carriage (2), a slide (3) equipped with guide means (4), braking means (5) associated
with the slide (3), and housing means (6) for the braking means (5); the carriage
(2), the guide means (4) and the housing means (6) are made in a single framework
(10).

[0001] This invention relates to an integrated framework for a braking device for door panels of sliding doors.
[0002] In recent decades, increasingly widespread use has been made of sliding doors, both in residential and in commercial and production buildings. That popularity on the real estate market is certainly attributable to the performance that such types of doors guarantee for users, both in terms of their linearity and elegance, particularly in the now dominant "pocket door" versions, and their practical operation. Even their cost has remained competitive, thanks to improvement and standardization of their production.
[0003] More recently, approximately in the last decade, there has been significant technological development in sliding doors, due to the use of devices that cause, particularly during the final step of closing of the door panel and during the inverse step of initial re-opening, automatic braking and therefore slowing of the speed of the door panel.
[0004] The result of this is improved control of said steps of use of the door, with reduced noise and inconvenience caused by banging and rebounding of the door panel against the doorjamb. Even a degree of risk of crushing hands, or even accidental breakage of door panels made of fragile material such as glass, are obviously avoided by such technology.
[0005] A limit encountered in the many prior art products in the sector is the fact such braking devices are usually associated with sliding carriages for door panels of standard sizes and types, therefore not very suitable for specific requirements that may arise in the many applications. In particular, it is impossible to apply a carriage and braking device of standard commercial lengths on door panels with a width of less than approximately 75 centimetres.
[0006] Another type of applications, now widely used on sliding doors, involves mounting a pair of braking devices on a single door panel, in such a way as to be able to control its speed in the separate steps of complete closing and opening. In that case, the mounting of the double device takes up more space, only available on door panels with a width roughly not less than 95 centimetres.
[0008] The invention, as described in the claims, achieves that aim by using a framework that fully accommodates all of the parts of the braking device, noticeably reducing its overall length.
[0009] The main advantage of this invention is basically the fact that its more compact form allows it to be used even on sliding doors with a much smaller width.
[0010] Another advantage of the invention is the fact that its integrated and complete production results in a lower production and marketing cost, and easier mounting during installation.
[0011] Further advantages and features of the invention are more apparent in the detailed description which follows, with reference to the accompanying drawings, which illustrate an example of it without limiting the scope of the invention, in which:
- Figure 1 is a perspective overview of the invention;
- Figure 2 is an exploded view, to better illustrate the parts, of a possible alternative embodiment of the invention;
- Figure 3 is a perspective view of a further possible alternative embodiment of the invention.
[0012] A braking device for door panels of sliding doors, which are provided with a fixed sliding guide g equipped with a projecting contrast element r, comprises, according to a layout widespread in the prior art, at least a carriage 2, a slide 3 suitable for interacting with the contrast element r and guide means 4 for the slide 3, braking means 5 associated with the slide 3 and housing means 6 for the braking means 5.
[0013] At least the guide means 4 and the carriage 2 are made in a single integrated framework 10. In a preferred embodiment, the housing means 6 for the braking means 5 are also integrated on the framework 10, which is therefore made in a single body, as illustrated in Figure 1.
[0014] In one possible alternative embodiment, the framework 10 comprises means 11 for association with the housing means 6 for the braking means 5, in such a way as to allow their interchangeability, as illustrated in Figure 2. In that way the overall length of the invention may be reduced according to the size of the door panel to which it will be applied.
[0015] The braking means 5 comprise at least one pair of pistons 5a, 5b, which are arranged in a parallel fashion in order to reduce the length dimension.
1. An integrated framework for a braking device for door panels of sliding doors, said
doors being provided with a fixed sliding guide (g) equipped with a projecting contrast
element (r), wherein the device (1) comprises at least a carriage (2), a slide (3)
designed to interact with the contrast element (r) and guide means (4) for the slide
(3), braking means (5) associated with the slide (3) and housing means (6) for the
braking means (5), characterised in that at least the guide means (4) and the carriage (2) are made in a single body.
2. The integrated framework according to claim 1, characterised in that it comprises the housing means (6) for the braking means (5), which are made in a
single body with the guide means (4) and the carriage (2).
3. The integrated framework according to claim 1, characterised in that the framework (10) comprises means (11) for association with the housing means (6)
for the braking means (5), so as to allow their interchangeability.
4. The device according to claim 1, characterised in that the braking means (5) comprise at least one pair of pistons (5a, 5b), which are arranged
in a parallel fashion so as to reduce the length dimension.
5. The device according to claim 1, characterised in that the braking means (5) comprise at least one pair of springs (5c, 5d), which are arranged
in a parallel fashion so as to increase their pulling force for closing the door panel.
6. The device according to claim 1, characterised in that the carriage (2) is integrated in a central position, at the side of the guide means
(4), in such a way as to reduce the overall length of the framework (10).
