Definitions

  • the present invention relates to a sliding support structure for drawers, particularly but not exclusively for industrial refrigerators and the like.
  • Structures for slidingly supporting drawers of the above type are known and comprise, on each side of a drawer, a fixed supporting profiled element which can be anchored to a refrigeration compartment and in which a guiding profiled element slides; said guiding profiled element can be anchored to the drawer, and at least one linear roller bearing is inserted between said profiled elements.
  • Sliding supports which are used exclusively in the field of furniture for civilian use, such as kitchens, desks or wardrobes made of wood or equivalent material, are known. Sliding supports for this use are generally entirely made of plastic and have rollers made of the same material. In some of these known supports, the roller cage can have a stop device which acts on the guiding profiled element which is anchored to the piece of furniture when the drawer is fully extracted and is released when the drawer is at least partially inserted, so as to facilitate the operation of inserting the drawer into the piece of furniture.
  • GB-A-2 101 880 in the name of Julius Blum GmbH discloses a sliding support for drawers of the above described type, in which the body of the support is made of elastically deformable plastic material and has, at the end directed toward the inside of the compartment, a lower protrusion which is suitable for penetrating in a corresponding cavity defined in the supporting profiled element which is anchored to the piece of furniture when the drawer is extracted completely from the compartment.
  • sliding and elastically flexible supports are provided by FR-A-2 311 514, and by GB-A-2 017 483.
  • the rollers can revolve on hubs which are pivoted on the cage, and one of them is movable along a vertical slot so that it is always in contact with the lower wing of the supporting profiled element.
  • the guide which is rigidly associated with said drawer interferes with the cage, forcing it to perform a slight tilting motion so as to disengage a cage locking tab from a corresponding hole defined in the supporting profiled element.
  • the roller cage is shaped so as to have considerable flexibility in a longitudinal direction so as to allow the engagement and disengagement of the stop elements. This considerable flexibility is undesirable in the sliding supports of drawers of industrial refrigerators which are the subject of the present invention, since, as mentioned above, said drawers require supports which have high rigidity and structural resistance in order to withstand the considerable loads involved.
  • the most severe disadvantage consists in the fact that the lower end of the guiding profiled element can accidentally collide against the internal walls of the cage before the front end of the profiled element has reached the bottom of the cage and before the drawer has rested on the sliding support in a substantially horizontal position. This fact causes the unwanted advancement of the cage and forces the operator to perform a series of tedious and complicated manoeuvres in order to extract the drawer completely, return the cage toward the outside of the compartment and retry to insert the drawer with the same likelihood of success. All this occurs with the additional disadvantage of operating at very low temperatures while the compartment of the refrigerator is kept open.
  • a further disadvantage of said known devices consists in the fact that the supporting profiled elements which accommodate the linear bearings must have cavities or similar local deformations which must be defined on the standard profiled elements, with a consequent burden in terms of manufacturing times and production costs.
  • German patent application No. 3044884 for example disclosed a sliding drawer having a stop element adapted to move elastically and vertically and adapted to engage a hole provided in the horizzontal support.
  • the aim of the present invention is to eliminate the disadvantages described above by providing a sliding support structure for drawers of industrial refrigerators which is very strong and reliable though it ensures optimum sliding conditions at low operating temperatures in the course of time.
  • a particular object of the present invention is to provide a sliding support structure for drawers which has a particularly simplified structure which can be obtained with large-series manufacturing processes at extremely low costs.
  • Another object of the present invention is to provide a structure which is extremely effective and reliable and can minimize the risk of unwanted and untimely disengagement of the stop devices upon insertion in the refrigeration compartment.
  • a further object of the present invention is to provide a sliding support for drawers which allows to use supporting and guiding profiled elements which can be associated with the cabinet and with the drawer without altering their standard configuration, so as to be extremely advantageous both from the economical point of view and from the point of view of installation and maintenance.
  • the sliding support structure according to the invention can be applied to each side of a drawer and generally comprises a supporting profiled element 1, a guiding profiled element 2 which can slide inside the supporting profiled element 1, and a linear bearing 3 which is interposed between the fixed profiled element 1 and the movable profiled element 2 to allow their mutual sliding with limited play.
  • the profiled element 1 has a generally C-shaped section and can be anchored to the internal wall of a refrigeration compartment, schematically indicated by the broken lines 1', whereas the profiled element 2 has at least partially an L-shaped sectional configuration and can be anchored to a side of a refrigeration drawer schematically illustrated by the broken lines 2'.
  • the linear sliding bearing 3 is formed by a substantially non-deformable and rigid roller cage 4 provided with supporting rollers 5.
  • the roller cage is conveniently constituted by a planar vertical core 6 which rigidly connects an upper roller-holder portion 7 to a lower roller-holder portion 8, both of which have a generally prism-like shape and are spaced so as to define a central compartment 4' of the cage.
  • Seats 9 are defined in the upper roller-holder portion 7, which extends for part of the total length of the cage, and corresponding rollers 5 which have a substantially horizontal axis can be inserted in said seats in a snap-together manner.
  • Seats 10 and 11 are defined in the lower roller-holder portion 8, which extends along the entire length of the cage 4, and corresponding rollers 5 with horizontal and vertical axes can be inserted in said seats in a snap-together manner.
  • Wedge-shaped scraper brushes 12 are provided at the ends of the lower roller-holder portion 8 and have the function of removing any formations of ice or frost located on the lower wing of the supporting profiled element 1.
  • a controlled stop device is advantageously provided at at least one of the ends of the rigid cage 4 and allows to lock the bearing 3 with respect to the supporting profiled element 1 when the drawer is completely extracted and to release said bearing when the drawer is at least partially inserted and in a substantially horizontal position.
  • the stop device 13 is constituted by an element 14 which can move elastically in a substantially vertical direction with respect to the cage 8.
  • the element 14 is an integral part of the vertical core 6 and is connected thereto by means of a pair of thin tabs or blades 15 which form elastic flexible links which can bend and flex substantially in the vertical plane of the core 6.
  • the number of blades 15 may of course be larger than two.
  • an engagement means is defined at the upper end of the element 14 and is constituted for example by a tooth 16 which is directed upward and defines a step or stop seat 17 suitable for interfering with an opposite front surface 18 of the outermost end of the supporting profiled element 1.
  • a lateral tab or protrusion 19 is provided in the lower part of the element 14 and has such a shape and orientation so as to define a cam for the actuation of the stop device.
  • the protrusion 19 has an upper surface 19' which is suitable for cooperating with the lower surface of the guiding profiled element 2, so as to cause the lowering of the element 14 and the consequent release of the tooth 16 from the abutment surface 18.
  • the lower portion 19'' of the tab 19 can partially enter a corresponding cavity 20 defined at the end of the lower roller-holder portion 8, thus allowing the vertical movement of the element 14.
  • the release of the stop element 17 from the front surface 18 occurs only when the guiding profiled element 2 is completely inserted in the compartment 4' of the cage 4 in a completely rested and substantially horizontal position.
  • the cage does not deform and cannot pull the stop element 17 downward. Therefore the likelihood of automatic and involuntary release before the drawer is rested horizontally on the cage is extremely low if not nil, differently from the supporting devices of the prior art.
  • the second embodiment of the structure according to the invention illustrated in Figure 5, has an element 14' which is defined monolithically from the cage core 6 and is connected thereto by means of a single tab 22 obtained by means of a cut 21.
  • the element 14'' is separate from, and independent of, the core 6 of the cage 4 and has a lateral tab or actuation cam 23 which is internally hollow so as to accommodate a spring or another similar elastic element 24. Said element tends to keep the stop tooth 16'' in raised position; said stop tooth has a seat 17'' for abutment against the front and vertical end surface 18 of the supporting profiled element 1.
  • the rollers 5 have a generally cylindrical shape and have slight circular depressions 5' on their lateral walls which are suitable for accommodating complementarily shaped protrusions 5'' defined in the lateral walls of the seats 9, 10, 11 of the upper and lower roller-holder portions 7, 8.
  • a second stop device 13, identical and symmetrical with respect to the first one, is preferably provided at the other end of the cage 4 and is normally kept in retracted position inside the supporting profiled element 1.
  • the upper roller-holder portion 7 supports the rollers 5 in an asymmetrical position with respect to the median line of the cage 6.
  • the horizontal wing 2'' of the guiding profiled element 2, and therefore the drawer 2', are thus protrudingly supported in a stable position, with the curved end 40 rested on the innermost roller of the upper roller-holder portion 7 and with the lower surface rested on at least two rollers of the lower roller-holder portion 8.
  • the presence of the second stop device at the other end of the cage allows to reverse the position of the sliding bearings 3 at the sides of each drawer, so that the upper roller-holder portion is in the position indicated by the broken line 7' in Figure 4 and the curved end 40 of the horizontal wing 2'' of the guiding profiled element 2 is kept in the innermost position indicated by the broken line 40''.
  • the fourth embodiment, illustrated in Figures 8 and 9, is conceptually similar to the preceding ones, but differs in that the engagement means are constituted by a flexible blade 22' which extends from the upper roller-holder portion 7 and has, at the outermost end, an engagement tab 14''' which has an appropriate shape so that it can be gripped by a user.
  • the tab 14''' In the part directed toward the inside of the compartment, the tab 14''' has a recess or internal seat 17''' which is suitable for engaging the front surface 18 of the upper wing of the supporting profiled element 1.
  • the engagement and disengagement of the tab 14''' from the supporting profiled element 1 do not occur automatically, but must be performed manually, and therefore the risk of unwanted sliding of the linear bearing 3 is completely eliminated.
  • the tab 14''' which is initially in engaged position, can be disengaged by means of an outward traction and of a downward release, occupying the positions schematically indicated in broken lines.
  • the supporting profiled element 1 is fixed directly to the internal compartment of the cabinet, and therefore the maximum stroke of the drawer is determined by the maximum protrusion of the guiding profiled element 2 with respect to the supporting profiled element 1.
  • the maximum stroke of the drawer is determined by the maximum protrusion of the guiding profiled element 2 with respect to the supporting profiled element 1.
  • FIG. 10 This situation is schematically illustrated in Figure 10, in which a linear bearing of the type shown in Figures 8 and 9 is used.
  • the supporting profiled element 1 conveniently has an ⁇ -like shape, with the ends 1', 1'' slidably coupled to the upper and lower wings 51, 52 of the anchoring profiled element 50 by means of respective cages 53, 54 which have rollers 55 with a vertical axis and rollers 56 with a horizontal axis.
  • rollers 5 of the cage 3 have, on their lateral walls, slight circular depressions 5' suitable for accommodating complementary protrusions 5'' defined in the lateral walls of the seats 9, 10, 11 of the upper and lower roller-holder portions 7, 8, as illustrated schematically in Figures 13 and 14.
  • a stop block 30 is furthermore provided and can be fixed, by virtue of appropriate anchoring means, to the upper wing 1' of the supporting profiled element 1 proximate to the outermost end, in order to prevent the complete extraction of the cage.
  • Said anchoring means can be constituted for example by a simple lateral longitudinal groove provided with upper and lower internal friction surfaces, respectively indicated by 30' and 30'', which can be forced against the upper wing 1'' of the supporting profiled element 1.
  • the rigid cage 4 can be manufactured by injecting into an appropriate mold an acetalic resin or the like, for example of the type produced and marketed by Dupont with the registered trade-mark DELRIN 500, optionally loaded with self-lubricating materials such as molybdenum disulfide.
  • the rollers may be made of the same synthetic resin which forms the cage or, optionally, for some of said rollers, of metallic material, such as for example stainless steel.
  • the scraper brushes 12 and the stop block 30 may also be made of a thermoplastic synthetic resin.
  • the supporting profiled element 1 and the guiding profiled element 2 are preferably made of metallic materials such as stainless steel or aluminum alloy, optionally coated with protective and self-lubricating layers.
  • the cage 4 provided with rollers 5 is inserted in the supporting profiled element 1, on which the stop block 30 is subsequently fixed in such a position that the stop tooth 16 skims the front end surface 18 of the supporting profiled element 1.
  • the horizontal wing 2'' of the guiding profiled element 2 is inserted in the compartment 4' of the cage between the upper and lower rollers of the linear bearing 3.
  • the horizontal wing 2'' acts on the lateral cam 19, causing it to lower, with the consequent disengagement of the stop tooth 17 from the front end surface 18 of the supporting profiled element 1, thus allowing the advancement of the guiding profiled element 2 with respect to the cage 4 and the advancement of said cage within the supporting profiled element 1.
  • the release of the cage occurs only after the manual disengagement of the tab 14''' from the end 18 of the supporting profiled element 1.
  • rollers 5 are substantially free and do not bear on rotation hubs or pivots, so that their friction with respect to the surfaces in contact is a pure rolling friction, without transmitting any tangential stresses at all.
  • the supporting profiled element 1 and the guiding profiled element 2 have no cavities or discontinuities, and that therefore no additional machining, besides their cutting to a selected length and their anchoring by means of appropriate connection elements on the fixed and movable parts of the drawer, is required.
  • the sliding support structure for drawers according to the invention fully achieves the intended aim, since it allows easy sliding even in the prohibitive environment due to the low operating temperatures of industrial refrigerators, with the assurance of long durability and constant functionality in the absence of corrosion.
  • the structure according to the invention is furthermore easy and simple to manufacture and most of all it is economical, by virtue of the possibility of being manufactured with simple and repetitive operations in large numbers.
  • rollers having a diameter of 15 mm and a width of 8 mm and with a cage core approximately 1.5 mm thick it is possible to easy bear drawers with a uniformly distributed load of approximately 60 kg.
