Definitions

• the present invention relates to a shock-absorber for sliding devices such as, for example, doors, windows, panels, gates, drawers.
• 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.
• 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.
• a decelerating device such as a hydraulic, pneumatic or spring cylinder
• Said decelerating devices do- not allow perfect and constant blocking of the sliding device in the end stop position.
• 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.
• the purpose of the present invention is to propose a shock-absorber able to overcome the drawbacks and limitations described above .
• FIG. 1 is an exploded view of the shock- absorber according to the invention.
• FIG. 1 is a view of the assembled shock- absorber
• FIG. 3 is a view from the opposite side of the assembled shock-absorber;
• FIG. 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.
• Figure 6 is an end view of the linear movement system.
• 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.
• 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.
• the shock-absorber 1 comprises a support body 10 bearing at least one decelerating device 20 and at least one magnet 40.
• the support body 10 is suitable for attaching near the end stop position of a sliding device 2.
• the decelerating device 20 is suitable for slowing down the travel of the sliding device 2 to the end stop position.
• the magnet 40 is suitable for attracting a corresponding magnetic or ferromagnetic element 45 borne by the sliding device 2, at least to block the sliding device in the end stop position.
• the decelerator 20 is a hydraulic decelerator.
• the decelerator 20 comprises a cylinder having a body 22 and a piston 23; when the moving load strikes the decelerator, the oil is pushed by the piston 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 .
• the magnet 40 exerts an attractive force which not only blocks the sliding device 2 when it reaches the end stop position, but which helps to bring the sliding device 2 , slowed down by the decelerating device 20, to said end stop position.
• the decelerating device 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.
• 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.
• the sliding device 2 reaches the end stop position at the same, controlled speed, caused only by the force of attraction exerted by the magnet 40.
• the decelerating device 20 and the magnet 40 are housed in respective seats 21, 41 made in the support body 10.
• said seats are parallel to each other and to the direction of sliding of the sliding device 2.
• the support body 10 comprises a main body 11 and a plug 12 placed so as to seal said main body 11, for example on the side of the sliding device 2.
• first and second cavities 21', 21"; 41', 41" facing each other which respectively form the seats 21, 41 for the decelerating device 20 and for the magnet 40, when said first and second cavities are flanking.
• the plug 12 is attached to the main body 11 by screws 13.
• the plug 12 is made in a magnetic material and the second cavity 41" for the magnet, that is the one made in the plug 12, is closed on the side facing the sliding device 2.
• the first cavity 21' for the decelerating device 20 houses the body 22 of said decelerating device 20; the plug 12 blocks said body 22 of the decelerating device 20 axially, for example by means of an annular boss 14 which engages the end of the body 22 of the decelerating device 20 axially; the second cavity 21" is a through cavity and houses the end part of the piston 23 of the decelerating device projecting from the body 22. Thanks to said through cavity 21", in other words, open towards the sliding device 2, such end of the piston 23 can be engaged by a portion of the sliding device 2.
• the assembly of the decelerating device 20 and of the magnet 40 to said body is simple and fast to perform. In fact all that is required is to place the decelerating device 20 and the magnet 40 in the first cavities 21', 41' made in the main body 11, place the plug 12 over them and attach it to the main body. The decelerating device 20 and the magnet 40 are thereby immediately and firmly blocked in their respective seats, without the need for specific means of attachment.
• the decelerating device 20 and the magnet 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.
• shock-absorber 1 is part of a translation system 3 of a sliding door 4 of the off-wall type.
• the support body 10 is suitable for assembling to the end of a translation guide 5 of the sliding door 4, for example having a substantially horizontal extension.
• a coupling seat 15 to the guide 5 is made in said support body 10, able to receive, for example via a shaped coupling, one end of the translation guide 5.
• Said translation system 3 comprises at least one carriage 6 joined in a translatable manner to the translation guide 5, for example sliding on said guide by means of at least one castor 7.
• the carriage 6 comprises coupling devices 8 to the door 4.
• the carriage 6 is provided with an end stop bracket 9 bearing a pin 9' suitable for engaging the piston 23 of the decelerating device 20.
• bracket 9 the magnetic or ferromagnetic element 45 suitable for interacting with the magnet 40 of the shock-absorber 1 is also housed.
• 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 the carriage 6, to house the castor 7 of the carriage when the latter is in the end stop position.
