Abstract
A guide and closure device for a cold room sliding door (1) comprises an overhead guide (2) positioned to correspond with a wall (16) of said cold room in which an aperture (14) is provided onto which the door (1), movable along said guide (2) via guided support means (20) associated with the door, closes; the support means (20) comprise eccentric means (33) cooperating with counteracting means (57) rigid with the guide (2) when the door corresponds with said aperture (14), said cooperation resulting in a first movement of the door (1) parallel to itself and to the cold room wall perpendicular to this latter, said support means (20) also cooperating with ramp means (21) arranged to move the door (1) relative to the guide (2) parallel to itself in a direction perpendicular to the guide simultaneously with said first movement when the eccentric means (33) cooperate with the counteracting means (57).
Description
- The present invention relates to a guide and closure device for a cold room sliding door, in accordance with the introduction to the main claim.
- A cold room is known to comprise, in a wall thereof, an aperture provided with a door which can either be hinged to said wall or be moveable along an overhead guide positioned parallel to said wall, with which the door cooperates via carriages inserted into said guide.
- With reference to this latter type of closure for cold rooms, the door has to approach the aperture by moving in a direction perpendicular to said wall while at the same time also moving perpendicular to the guide when it approaches the aperture to close it, or when withdrawing therefrom to release it in order to allow access to the cold room. The purpose of this is to enable the gaskets associated with the door to achieve optimal sealing against the wall.
- The movement perpendicular to the guide also enables the door to be raised from a surface or floor above which it moves, to prevent any non-uniformity in the level of the floor from blocking the movement of the door, should this come into contact with it.
- To achieve these movements, the overhead guide usually presents an insert comprising at least one portion having a plane inclined towards the floor and presenting a guide edge for the carriage which causes it (together with the door) to approach the wall.
- This solution, although simple, means that the guide must be provided with said insert, which must have the correct dimensions to enable the door to precisely close onto the wall aperture. It follows that manufacturers of cold room guide and closure devices are required to produce inserts of different lengths depending on their use, in order to dispose the inclined plane portions and the guide edge in the correct position to enable the door to close precisely. Alternatively, the final user or installer of the guide has to cut said insert (in this case of standard length) to size and correctly position the inclined plane portion at the optimum guide point, on installing the door guide and closure device.
- All this is complicated, in addition to increasing the time for producing and/or mounting the guide of said device, and increases the costs of this latter.
- An object of the invention is to provide a guide and closure device for a cold room sliding door which represents an improvement over known solutions.
- A particular object of the invention is to provide a device of the stated type which is of universal use, independent of the width of the cold room aperture onto which the door is required to close.
- Another object of the invention is to provide a device of the stated type which is of simple installation and reliable use.
- A further object is to provide a device which, precisely because of its universality, requires no intervention on the overhead guide, such as to adapt it to the size of the cold room aperture.
- These and other objects which will be apparent to the expert of the art are attained by a device in accordance with the accompanying claims.
- The present invention will be more apparent from the accompanying drawings, which are provided by way of non-limiting example, and in which:
-
Figures 1 and2 are perspective views of a device of the invention associated with a sliding door shown in the open and closed position respectively; -
Figures 3 and4 are views from above of the device of the invention shown inFigures 1 and2 respectively; -
Figure 5 is a perspective exploded view from above, of the device ofFigure 1 ; -
Figure 6 is a perspective exploded view from below, of the device ofFigure 1 ; and -
Figure 7 is a longitudinal section through the device ofFigures 5 and6 when assembled. - With reference to said figures, a guide and support device for a sliding
door 1 comprises anoverhead guide 2 positioned at anupper end 3 of thedoor 1. This latter comprises abody 4 withlateral sides flat faces sides end 3, theflat face 10 presents a seal orgasket element 11 arranged to cooperate withedges 12 of anaperture 11 provided in awall 16 of a cold room. By virtue of thegasket 11, the door is able to seal against theaperture 14, and can be withdrawn from this aperture to enable access to the cold room, by moving along theoverhead guide 2 on acarriage 18 movable within this latter. - More particularly, the device of the invention comprises support means 20 carrying the
carriage 18 and ramp means 21, these means 20 and 21 enabling thedoor 1 to move parallel to itself, in a direction perpendicular to thewall 16 and perpendicular to theguide 2 respectively, such as to enable said door to sealedly close onto theaperture 14 or to withdraw therefrom to enable access to the cold room interior. - A
bracket 25 is fixed (byscrews 26 cooperating withholes 27 in the respective side) along eachlateral side upper end 3 of the door 1) supporting anannular bush 30 projecting from the bracket and having anupper end 31 and alower end 32. At theupper end 31 of the bush 30 a member 33 (forming part of the support means 20) is present presenting alower face 34 having a flatperimetral edge 35 resting on saidedge 31 and within which a circular sector-shaped surface 36 is present, projecting from saidface 34. - A
hole 39 passing through themember 33 and positioned eccentrically about the longitudinal central axis W of said member opens into theface 34 at a hollowlateral portion 36A of saidsurface 36. Positioned within theeccentric hole 39 there is ashaft 40 having a first threadedportion 41, a secondintermediate portion 42 and athird end portion 43 opposite theportion 41 and separated from the second portion by acollar 46 projecting laterally from the shaft. Thiscollar 46 rests on a recessed upper face 47 of themember 33, into whichother holes 50 open to containscrews 51 which fix themember 33 to afirst ramp member 54 forming part of the ramp means 21 and described hereinafter. - The
portion 43 of theshaft 40 carries thecorresponding carriage 18, while theportion 42 presents ahole 55 to contain apin 55A, the function of which is described hereinafter. - The
member 33 presents a laterally projectingfork 56 cooperating with actuator means for moving the door relative to thewall 16 such as to move the door onto theaperture 14 or to withdraw it therefrom. These actuator means are for example a correspondingcounteracting member 57 rigid with theguide 2. This member is carried by abracket 58 which can be welded directly to theguide 2 or be rigidly secured thereto by an embracingelement 160 mounted movable on said guide and fixed in a suitable position thereon in any known manner, for example by screws (not shown). Theguide 2 comprises twoelements 160 positioned apart by a distance substantially equal to that of the access width of theaperture 14. Their cooperation with thefork 56 of themembers 33 provided on bothlateral faces door 1 enables thedoor 1 to be made to approach thewall 16 by movement parallel to itself and by cooperation between said forks and said counteractingmembers 57, this cooperation resulting in rotation of eachmember 33 about theshaft 40, this rotation being eccentric about the central axis W of said member and hence of thecorresponding bush 30, and which enables the door to move parallel to itself towards thewall 16, i.e. in a direction perpendicular to this latter. - As stated, the
member 33 is fixed byscrews 51 to thefirst ramp member 54, this latter cooperating with asecond ramp member 60 to enable the door to move parallel to itself and perpendicular to theguide 2. - More particularly, the
first ramp member 54 comprises abody 61 having aportion 63 to be inserted into thebush 30. On thebody 61, at the base of theportion 63, a step is hence present on which thelower end 33 of thebush 30 rests. - The
portion 63 presents a first recessed free end defining the upperfree face 64 of themember 54; thecavity 64A of this end orface 64 has a shape corresponding to that of thesurface 36 of the saidmember 33 and presents on one side aprojection 66 of shape corresponding to the hollowlateral portion 36A ofsaid surface 36. In this manner, this latter sits in thecavity 64A and is engaged therewith by a form fit which, together with the presence of thescrews 51, renders themember 54 rigid with themember 33. - The
first ramp member 54 comprises a perimetral collar orstep 67 on which thebush 30 rests. From anend face 68 opposing theface 64, a structure projects comprising inclined planes and/orramps 69 and positioned to the inside of said face, which hence comprises aflat part 70. Thestructure comprising ramps 69 bounds a throughhole 71 of themember 54 to receive theshaft 40. - This latter also penetrates through a
hole 72 of thesecond ramp member 60 presenting anupper end 7 with a plurality ofupper ramps 76 arranged to cooperate with theramps 69 of themember 54, and a secondflat end 79 into which thehole 72 opens and where there also opens arecess 80 of elongate shape having its axis perpendicular to that of the hole 72 (coinciding with the axis K of theshaft 40 eccentric to the axis W of the member 33). This hole houses thepin 55A inserted into thehole 55 of theshaft 40 to render thesecond ramp member 60 rigid with this latter and static relative to the first ramp member 54 (rigid with themember 33 and movable therewith about theshaft 40, which is fixed). - The
pin 55A is locked in therecess 80 by awasher 83 and retainingring 84 mounted on theportion 42 of theshaft 40. On this latter anannular disc 85 is also mounted having opposingflat faces first end 86 of aspring 87 surrounding the entiresecond ramp member 60 rests on theface 85A, itssecond end 88 resting on theflat part 70 of theface 68 of thefirst ramp member 54. - A thrust bearing 90 acts on the second (lower)
face 85B of the disc and is urged against this face by anut 91 and lockingnut 92 screwed into the threadedportion 41 of theshaft 40. The nut and locking nut (replaceable by a self-locking nut) can be positioned at various levels along theend 41 of the shaft, to enable thedisc 85 to be positioned at greater or lesser closeness to thesecond ramp member 60. The result of this is that thespring 87 can be compressed to a greater or lesser extent between said disc and thefirst ramp member 54; in this manner the preload of said spring can be modified such that it is able to exert a greater or lesser thrust on thefirst member 54 and hence on thebush 30, this thrust contributing to raising the door parallel to itself towards theguide 2 at the commencement of opening. - The function of the spring is hence to facilitate opening of the
door 1 by overcoming part of its weight, which is made to act entirely on theshaft 40 via thebearing 90 with thedisc 85 and theretaining ring 84 with thewasher 83, and via thesecond ramp member 60. The spring overcomes part of the weight of the door by thrusting it towards theguide 2, this thrust being adjustable by thenut 90 and lockingnut 91. Hence the door weight does not completely bear on theramp member 60 and on theramp member 54, with the result of considerably facilitating the rotation of theramp member 54 relative to the fixedramp member 60 at the commencement of door opening (raising). - During use, assuming the door to be initially open (situation corresponding to the position of the
ramp members Figure 7 ), the door is slid along theguide 2 until itssides members 57. At this point theforks 56 of themembers 33 of the support means 20 enter into cooperation with said counteracting means to cause saidmembers 33 to rotate about theshaft 40 with the continuing movement of the door along the guide. - By virtue of the eccentricity of the shaft to the axis W of the
members 33, these undergo a rotation about the shaft which moves thedoor 1 parallel to itself towards theaperture 14 in thewall 16, said movement taking place in a direction perpendicular to this latter. - Simultaneously, as the
first ramp member 54 is rigid with themember 33 and the second ramp member is rigid with the (fixed)shaft 40, there is also a relative movement between these members with a mutual movement of theramps members bush 30 on thefirst ramp member 54, is lowered relative to the guide, to move perpendicular to it and parallel to itself. - The combination of this movement simultaneously with that of the approach to the
door 16 results in the door closing onto theaperture 14. This is achieved without providing for anything to be associated with theguide 2, which can hence be a simple standard profile bar of any length. - The entire door movement hence derives from members associated with the door itself, their position on the door not depending on the width of the
aperture 14. Having constructed thedoor 1, themeans guide 2 or on said means. - The door is evidently opened by the
means - The device of the invention is easily positioned on the door, this being a rapid operation not requiring intervention on the overhead guide.
- One embodiment of the invention has been described. Others are however possible in the light of the aforegoing and are to be considered as falling within the scope of the following claims. For example, the actuator means for moving the door relative to the
wall 16 and to theaperture 14 can be an electro-piston associated preferably with thetop 3 of thedoor 1, cooperating with eachfork 56 and activated by a switch operated manually or automatically (for example by position sensors sensing when the door is positioned at the aperture 14). Alternatively, these actuator means can be at least one pneumatic or hydraulic piston.
