Definitions
- the subject of the present invention is a device for suspending a suspended sliding door closing under the effect of its own weight, in particular for refrigeration installation, and provided for this purpose with at least one roller cooperating with a ramp to spread the door of its frame when it is opened by moving the door parallel to its plane.
- the present invention aims to eliminate the fixed running rail, to simplify the entire device and make its use and mounting much more flexible, that is to say much better adaptable to all door widths.
- the device according to the invention is characterized in that it comprises at least two suspension links hinged to the door about a horizontal axis and rigidly connected by a bent part to a horizontal cylindrical bar and rollers of bearing, the axes of which, at least approximately horizontal, are fixed above the door, these rollers supporting the cylindrical bar by a groove in which the cylindrical bar can move both in translation and in rotation, practically without friction.
- the fixed rail is replaced by rollers between which it is without other possibility to pass a transport rail, for example a butcher rail.
- the number of rollers can be chosen according to the width and weight of the door.
- the cylindrical suspension bar can be constituted by a simple cylin tube drique, preferably reinforced inside by a tube of polygonal section, for example a square tube. This bar can be cut to length on site, the ends of the tube then being provided with frustoconical end pieces so as to facilitate engagement of the ends of the tube on the rollers.
- rollers made of self-lubricating material for example Delrin (registered trademark)
- the door is moved almost without friction and silent. All the suspension elements can be delivered as a kit and mounted without difficulty by the user on doors of different dimensions.
- the door 1 is further provided, in a manner known per se, with two rollers 19 and 20, with a vertical axis intended to roll on ramps 21 and 22, to separate the door from its frame, as described in the patents CH 557 466 and 581 250, these ramps being followed respectively by a raceway 23.24.
- the door is provided, in a manner known per se, with two ramps 25 and 26 cooperating respectively with rollers 27 and 28 fixed to the ground to apply the door, more precisely the seal thereof, against the frame in the closed position.
- the door can be opened manually by means of a recessed handle 29.
- the rollers of the suspension device for example the rollers 9 and 14, are preferably made of Delrin (registered trademark) and are mounted, by means of ball bearings such as 30, on fixed axes 31 and 32 constituted by bolts, the heads of which are welded to a plate 33 aimed in the wall 3 by means of four bolts 34, 35, 36 and 37.
- Spacers 38 and 39 ensure the positioning of the bearings to balls held by a nut 40.
- the rollers have a groove 41 of trapezoidal section.
- the link 5 consists of several parts so as to simultaneously form a shock absorber. It comprises a casing 42 constituted by a rectangular tube open at its lower part. This housing is closed at its upper part by a plate 43 from which hangs a rod 44 constituted by a bolt retained by a nut 45 and whose head 46 retains a rectangular block 47 capable of sliding in the casing 42.
- the rod 44 is surrounded by a spring 48 working in compression between the block 47 and the plate 43.
- the rectangular block 47 is pierced with a hole 49 over its entire length, in which are engaged two axes 50 and 51 fixed in the part 47 by means of two screws blocking such as 52 accessible through two holes 53 and 54 formed in the wall of the casing 42.
- the axes 50 and 51 engage respectively in two vertical wings 55 and 56 of a support plate 57 fixed to a frame 58 of the door 1 by means of bolt.
- the axes 49 pass through the side walls of the casing 42 through two oblong holes allowing adjustment, as well as a flap of the rod 44 in the casing, the spring 48 ensuring a certain flexibility of the connecting rod in the direction of compression.
- the cylindrical suspension bar 6 is constituted by a tube of common circular section, for example made of aluminum, reinforced by a tube of square section 59 whose external diagonal is equal to the inside diameter of the tube 6.
- the tubes 6 and 59 are rigidly connected to the rods, for example to the rod 5, by two bolts 60 and 61, the heads of which rest on the square tube 59 and which pass through the casing 42, a nut being interposed between the casing 42 and the tube 6.
- FIG 3 shows the suspension device while the door is closed.
- the rollers 19 and 20 mount on the rails 21 and 22 and the door departs from its frame in the approximate direction of arrow F2 (fig. 3).
- this articulation drives the tube 6 in rotation about its virtual axis in the direction F3.
- the movement of the door is therefore a translational movement along a trajectory in an arc of a circle around the virtual axis of the tube 6. Since the suspension rollers simultaneously roll on the tube 6, the movement of the tube on the rollers s 'performs practically without friction.
- the jolts of the door during a somewhat abrupt closing or opening are absorbed by the springs 48, so that these shocks are not transmitted to the tube 6, to the rollers and to their bearings.
- the suspension rods could consist of a single piece welded or screwed to the tube 6.
- the bend between the rod and its means of attachment to the tube need not necessarily form an angle of 90 ° .
