- Always according to the invention said kit can comprise a magnet.
- The present invention will be now described, for illustrative but not limitative purposes, according to its preferred embodiments, with particular reference to the figure of the enclosed drawing, showing a longitudinal section view of a counterframe with a sliding door with the device for closing and dampening according to the invention.
- Making reference to the enclosed figure, it is possible observing a door, generically indicated by reference number 1, comprising a counterframe, provided with a bow, a sliding
traverse 2 and an abutting upright 3. - Door 1 also comprises a
wing 4, sliding coupled with said sliding transverse 2 by carriages (not shown), said carriages sliding along a track (not shown as well), not making part of the invention. - Door 1 comprises a closing and dampening device, generically indicated by
reference number 5, in order to permit closure ofwing 4 regardless its position, permitting to the same reaching abutment upright 3 with a slow down motion, accompanying its motion. - Closing and
dampening device 5 comprises acounterweight 6, sliding vertically when said wing passes from the open to the closed position and vice versa, suitable to cause push determiningwing closure 4. - As it can be observed from figure,
counterweight 6 moves vertically, but it is obliged to horizontally move integrally with said wing (direction indicated in the figure by arrow A). - Said
counterweight 6 is connected at the first end of afirst cable 61. Second end of saidfirst cable 61 is fixed to said slidingtraverse 2, in a first intermediate point of the same indicated by reference P1.First cable 61 further passes through apulley 62 fixed to thewing 4. - In the present embodiment, point P1 is preferably positioned in an intermediate position between the projections on sliding
traverse 2 of the lateral edges of thewing 4 when the latter is in the closed position, i.e. when front edge is close to the abutment upright 3. -
Device 5 also comprises a dampening cylinder 7, substantially vertical, parallel with respect to the rear edge ofwing 4, with apiston 8, housed within said dampening cylinder 7 and sliding within the same. Dampening cylinder 7 acts as brake of thewing 4 motion, always permitting in any case to thewing 4 to close, regardless the intermediate open position of the wing, thus opposing to the gravity force oncounterweight 6. - Said dampening cylinder 7 has a first
upper end 71 open and a secondlower end 72 closed by a one-way valve 9, suitable to prevent sucking air during lifting movement of thepiston 8, the operation of which will be described in greater detail in the following. -
Counterweight 6 is sliding coupled with said dampening cylinder 7 by suitably shapedfirst supports 10. - Said dampening cylinder 7 is also fixed to said
wing 4 by a pair of second fixedsupports 11. - Said
piston 8 is coupled in point P2 with asecond cable 81, fixed to the slidingtraverse 2, and transmitted by apulley 83 and achannel 82. Saidchannel 82 is provided within atransmission block 84 fixed to the rear end of the same slidingtraverse 2. - Finally, closing and dampening
device 5 also comprises amagnet 12, fixed to the secondlower support 12, suitable to keepwig 4 in an open position, acting on a fixed metallic element that in the present case can be the same box on the door 1. - Dampening cylinder 7 is preferably comprised of aluminium, while
supports device 5. - Preferably, said
cables - In a further embodiment, dampening cylinder 7 can be provided in different positions, e.g. along the sliding
traverse 2 or on the bottom of the box. - Furthermore, other closure means can be used instead of
counterweight 6. Among these alternative solutions, it is possible thinking using a spring that can apply a constant force onclosure wing 4. - Closing and dampening
device 5 operates as follows. Whenwing 4 is in an opening position,counterweight 6 is positioned above, close the second fixedsupport 11, thus in a maximum potential energy condition. Instead,piston 8 is close thesecond end 72 of said dampening piston 7. - In
case wing 4 is abutting against upright,magnet 12 will maintain the same adhering to the rear side of metallic box, preventing its closure. - Even exerting a minimum traction in order to overcome
wing maintaining wing 4 bymagnet 13, saidwing 4 will be free to close. In this situation, and for all other open situations, even of partial opening, ofwing 4,counterweight 6 ill exert its action, giving to wing 4 a push necessary and sufficient to start closure motion. - At the same time,
piston 8 will start its run upward, thus creating a vacuum within lower portion of dampening cylinder 7, included betweenpiston 8 andvalve 9, which is in a closure condition. - Therefore, air flows along dampening cylinder 7 passing only between the same dampening cylinder 7 and
piston 8. In view of the strict tolerance between outer diameter ofpiston 8 and inner diameter of dampening cylinder, a small amount of air will pass, thus slowing downpiston stroke 8 and consequentlywing stroke 4 up to impact againstclosure abutment upright 3. - Suitably adjusting length of
second cable 81, it is possible adjusting part wherewing 4 is slowed down with respect to the whole lumen of door 1, thus retarding or not intervention ofpiston 8. In other words, it is possible adjustingwing 4 whereinpiston 8 starts sliding within dampening cylinder 7. Before,wing 4 will be free to slide until whensecond cable 81 is tightened and starts draggingpiston 8, thus lifting the same. - During the opening of the door 1,
piston 8 is free to descend by gravity along its seat, thanks to the fact thatvalve 9, being open, permits ejection of air contained within lower part of dampening cylinder 7, during the ascending stroke of thesame piston 8. - It must be taken into consideration that
counterweight 6 andpiston 8 have such a weight to permit closure of the door regardless the position of thewing 4, a suitable for every kind (weight) of commercial door. -
Device 5 according to the invention can be both installed in new doors, and retrofitted in existing doors 1 and counterframes not providing such a kind of device. - Particularly, installation operations of a device according to the invention will be described, taking into consideration the case of a sliding door 1 comprising a box (not shown), already installed, destined to replace by its volume a portion of the wall, and a
wing 4 sliding coupled with the sliding traverse. - In such a case, in order to install a
device 5 within door 1, the following steps are carried out: - dismounting
wing 4 and relevant sliding carriages from said slidingtraverse 2; - introducing
transmission block 84, having saidtransmission channel 82, in said slidingtraverse 2; - pushing said
transmission block 84 until the rear end of said slidingtraverse 2; - fixing
magnet 12 to the second lower support; - fixing said pair of fixed
supports 11 of said cylinder 7 to the rear lateral edge of saidwing 4; - installing again said sliding carriages and said
wing 4 into said slidingtraverse 2; - placing said
wing 4 in an opening position, maintained in said position thanks to the coupling action of saidmagnet 12 with the metallic bottom of said box; - pulling said
first cable 61 until fully lifting saidcounterweight 6, putting it close to the second upper fixedsupport 11; - fixing the free end of said
first cable 61 to said first fixing point P1; - placing said

cables - It is noted that
device 5 for dampening the movement according to the invention is always covered by counterweight, being rear edge of the wing hidden by box. - Solution according to the present invention has the advantage of permitting closure of a door wing regardless its position.
- A further advantage of the present invention is that said device can be also easily installed in already existing doors not provided with such a closure system.
- It is still an advantage of the present invention that of permitting an adjustment of the position and of the wing dampening force during the closure movement.
- The present invention has been described for illustrative but not limitative purposes, according to its preferred embodiments, but it is to be understood that modifications and/or changes can be introduced by those skilled in the art without departing from the relevant scope as defined in the enclosed claims.
