Description
- The present invention relates to a shock-absorber for sliding devices such as, for example, doors, windows, panels, gates, drawers.
- The use of shock absorber stop devices mounted near the end stop position of a sliding device so as to prevent brusque impact of said sliding device against the rigid stop delimiting the travel is known of.
- Normally, such shock absorber devices use a decelerating device, such as a hydraulic, pneumatic or spring cylinder, which brakes the sliding device when it is about to reach the end stop position.
- Said decelerating devices, however, do not allow perfect and constant blocking of the sliding device in the end stop position. In particular, the sliding device almost always rebounds, more or less depending on the thrust imparted, and tends to return backwards rather than blocking in the end stop position.
- In some cases, if the thrust imparted to the sliding device by the user is not well-judged or if the shock absorber device is not properly calibrated, it is not possible prevent violent impact against the end stop, causing unwanted banging and progressive wear of the parts hitting against each other.
- In the case in point, of off-wall sliding doors or panels and, in particular, with visible guide and translation mechanisms, the need to slow down the impetus of the door or panel in a controlled manner also contrasts with constraints of an aesthetic nature which such types of fixture or partition impose, and this conflict has not yet been resolved satisfactorily.
- The purpose of the present invention is to propose a shock-absorber able to overcome the drawbacks and limitations described above.
- Such purpose is achieved by a shock-absorber according to claim 1 and by a linear movement system according to
claim 9. The dependent claims describe preferred or advantageous embodiments of the invention. - The characteristics and advantages of the shock-absorber according to the invention will however be evident from the description below, made by way of a nonlimiting example, of its preferred embodiments with reference to the attached figures, wherein:
-
Figure 1 is an exploded view of the shock-absorber according to the invention; -
Figure 2 is a view of the assembled shock-absorber; -
Figure 3 is a view from the opposite side of the assembled shock-absorber; -
Figure 4 is an exploded view of one end of a linear movement system of a glass door according to the invention; -
Figure 5 is a front view of the end of the movement system; and -
Figure 6 is an end view of the linear movement system. - In said diagrams, reference numeral 1 globally denotes, in its entirety, a shock-absorber for sliding devices such as sliding doors or windows, panels, gates, drawers and the like, according to the invention.
- For the sake of simplicity and if not specified otherwise, henceforth in the description sliding device will be taken to mean both the main element made to slide, such as the door, window, panel, gate and any mobile means supporting it to enable movement, where envisaged.
- In a general embodiment, the shock-absorber 1 comprises a
support body 10 bearing at least one deceleratingdevice 20 and at least onemagnet 40. Thesupport body 10 is suitable for attaching near the end stop position of asliding device 2. The deceleratingdevice 20 is suitable for slowing down the travel of thesliding device 2 to the end stop position. Themagnet 40 is suitable for attracting a corresponding magnetic orferromagnetic element 45 borne by thesliding device 2, at least to block the sliding device in the end stop position. - According to the invention, the
decelerator 20 is a hydraulic decelerator. Thedecelerator 20 comprises a cylinder having abody 22 and apiston 23; when the moving load strikes the decelerator, the oil is pushed by thepiston 23 through a series of brake holes. The number of holes which the oil comes out of decreases progressively and proportionately to the deceleration travel. - In one advantageous embodiment, the
magnet 40 exerts an attractive force which not only blocks thesliding device 2 when it reaches the end stop position, but which helps to bring thesliding device 2, slowed down by the deceleratingdevice 20, to said end stop position. - Even more preferably, for an average force applied to the
sliding device 2, the deceleratingdevice 20 is calibrated to stop the sliding device before it reaches the end stop position, and the magnet exerts a greater force of attraction on the sliding device than the contrast force opposing the decelerating device, so as to attract the sliding device to the end stop position. - In this way, the
sliding device 2 is prevented from always hitting against the shock-absorber as a result of the thrust imparted by the user, damaging it if the thrust is violent or in any case causing progressive wear. On the contrary, thanks to such calibration of the deceleratingdevice 20 and of themagnet 40, in most cases thesliding device 2 reaches the end stop position at the same, controlled speed, caused only by the force of attraction exerted by themagnet 40. - The decelerating
device 20 and themagnet 40 are housed inrespective seats support body 10. For example said seats are parallel to each other and to the direction of sliding of thesliding device 2. - According to the invention, the
support body 10 comprises amain body 11 and aplug 12 placed so as to seal saidmain body 11, for example on the side of thesliding device 2. In themain body 11 and in theplug 12 are obtained first andsecond cavities 21', 21"; 41', 41" facing each other which respectively form theseats decelerating device 20 and for themagnet 40, when said first and second cavities are flanking. For example, theplug 12 is attached to themain body 11 byscrews 13. - Advantageously, the
plug 12 is made in a magnetic material and thesecond cavity 41" for the magnet, that is the one made in theplug 12, is closed on the side facing thesliding device 2. - The first cavity 21' for the decelerating
device 20, in other words the one made in themain body 11, houses thebody 22 of said deceleratingdevice 20; theplug 12 blocks saidbody 22 of the deceleratingdevice 20 axially, for example by means of anannular boss 14 which engages the end of thebody 22 of the deceleratingdevice 20 axially; thesecond cavity 21" is a through cavity and houses the end part of thepiston 23 of the decelerating device projecting from thebody 22. Thanks to said throughcavity 21", in other words, open towards thesliding device 2, such end of thepiston 23 can be engaged by a portion of thesliding device 2. - Given such embodiment of the body of the shock-absorber, the assembly of the decelerating
device 20 and of themagnet 40 to said body, is simple and fast to perform. In fact all that is required is to place the deceleratingdevice 20 and themagnet 40 in the first cavities 21', 41' made in themain body 11, place theplug 12 over them and attach it to the main body. The deceleratingdevice 20 and themagnet 40 are thereby immediately and firmly blocked in their respective seats, without the need for specific means of attachment. - In addition, the decelerating
device 20 and themagnet 40 are practically hidden from view and the shock-absorber 1 presents a compact and regular body, for example of a substantially prismatic shape, suitable for visible applications. - In a practical example of one embodiment, illustrated in figures
figure 4-6 , the shock-absorber 1 is part of atranslation system 3 of a slidingdoor 4 of the off-wall type. - In particular, the
support body 10 is suitable for assembling to the end of atranslation guide 5 of the slidingdoor 4, for example having a substantially horizontal extension. To such purpose, acoupling seat 15 to theguide 5 is made in saidsupport body 10, able to receive, for example via a shaped coupling, one end of thetranslation guide 5. - Said
translation system 3 comprises at least onecarriage 6 joined in a translatable manner to thetranslation guide 5, for example sliding on said guide by means of at least onecastor 7. Thecarriage 6 comprisescoupling devices 8 to thedoor 4. - In addition, the
carriage 6 is provided with anend stop bracket 9 bearing a pin 9' suitable for engaging thepiston 23 of the deceleratingdevice 20. In saidbracket 9 the magnetic orferromagnetic element 45 suitable for interacting with themagnet 40 of the shock-absorber 1 is also housed. - It is to be noted that the
support body 10, for example of a cylindrical shape or having an elliptical section presents, in the specific embodiment shown, a slot or groove 17, in a rearward position in relation to the end facing thecarriage 6, to house thecastor 7 of the carriage when the latter is in the end stop position. - A person skilled in the art may make modifications, adaptations and replacements of elements with others functionally equivalent to the embodiments of the shock-absorber according to the invention so as to satisfy contingent requirements while remaining within the sphere of protection of the following claims. Each of the characteristics described as belonging to a possible embodiment may be realised independently of the other embodiments described.
