Description

Technical Field

[0001] The present disclosure relates to a sliding track, such as a sliding track used with a sliding barrier. In particular, the present disclosure relates to a sliding track for a sliding device, a sliding device including the sliding track, and a sliding barrier system including the sliding device. Background Art

[0002] Linear sliding furniture supports in the form of sliding systems are known in the art and have been used in a variety of structures including retractable tables, chests of drawers, retractable sofa beds, sliding doors, etc. in the home. They are relatively simple, reliable in structure and easy to use. In particular, wardrobes with sliding doors are well known in the art (see, for example, DE 298 13 478). Usually, the door is provided with a supporting ball bearing at the upper end of the door, such as a roller rolling on a track, and a steering device, such as a pin, is arranged at the lower end. The ball bearing works well, but is a little sensitive to dust. When using the ball bearing, the start-stop resistance is very low, which means that in some cases, the sliding door can be easily moved from its static position. At the end position, this problem can be partially overcome by providing a static end position provided with, for example, a head or recess for a wheel. However, this does not overcome the low start-stop resistance at the intermediate position.

[0003] Sliding kitchen doors, which are lighter than wardrobe sliding doors, are usually not equipped with ball bearings, but are mounted vertically in sliding grooves, i.e. linear sliding bearings. This may work for lighter doors, although the sliding resistance may be greater, especially at the start of the movement. However, for heavier doors, such as wardrobe sliding doors, linear sliding bearings usually offer too much sliding resistance for practical use, especially at the start of the movement. In addition, such linear sliding bearings are very sensitive to dirt contamination, which can have a very negative effect on the sliding resistance.

[0004] WO 2017 / 042201 discloses a sliding barrier system for a sliding barrier comprising a linear sliding track and at least one sliding member. The linear sliding track is preferably a metal rail, such as an aluminum rail or a steel rail, and has a sliding surface coated with a paint comprising a resin and a lipophilic composition coating. Metal sliding tracks are heavy, rigid, require surface treatment such as painting, and are complex and expensive to manufacture.

[0005] Therefore, there is an interest in providing a simple, inexpensive, safe device for providing a sliding device with lower friction for lighter sliding furniture applications. The reduced friction should preferably be permanent and easy to manufacture. In addition, the sliding device should preferably be substantially maintenance-free. In particular, it is desirable to provide a sliding track and a sliding device with very low sliding friction. Such a sliding track and a sliding device may find use in sliding barrier systems, for example for use with wardrobe sliding doors. In particular, the sliding track may find use in wardrobes, cupboards, etc. having sliding doors and a lower plate to which the track is to be assembled. Summary of the invention

The sliding track can be made of plastic, and therefore the disadvantages associated with metal sliding tracks can be avoided. This provides a low-friction sliding track and sliding device with efficient functions in many applications, including furniture applications such as sliding doors, drawers, tables, retractable bed frames and retractable beds.

[0038] The following disclosure relates to a slide track for a slide device, a slide device including the slide track, and a slide barrier system including the slide device. The slide track, slide device, and slide barrier system disclosed herein provide a simpler, safer, inexpensive, easy to manufacture, and substantially maintenance-free device for providing sliding with lower friction for lighter sliding furniture applications.

[0039] Figure 1 1 is a perspective view of a first sliding barrier system 10 for a sliding door, the first sliding barrier system 10 comprising a sliding barrier 400, a first or main sliding device 300-1 and a second or secondary sliding device 300-2. The main sliding device 300-1 is arranged at the lower end of the sliding barrier system 10 and is adapted to support the weight of the sliding barrier 400. The secondary sliding device 300-2 is arranged at the upper end of the sliding barrier system 10 and is adapted to manipulate the sliding barrier 400 during the sliding movement defined by the main sliding device 300-1.

[0040] Each of the main sliding device 300-1 and the secondary sliding device 300-2 includes a sliding track 100. The first sliding track 100-1 is adapted to be rigidly connected to the lower platform 200-1 in a concave configuration so that the sliding barrier 400 can move relative to the lower platform 200-1. The sliding track 100-1 is adapted to support the weight of the sliding barrier 400. The second sliding track 100-2 is adapted to be rigidly connected to the upper platform 200-2 in a concave configuration. The sliding barrier 400 is configured to slide along the sliding track 100 in a sliding direction A relative to the platform 200.

[0041] Each of the lower platform 200-1 and the upper platform 200-2 forms part of a piece of furniture, in this case a lower panel and an upper panel of a wardrobe. The sliding barrier system 10 may alternatively be arranged in a cupboard, a cupboard, a sideboard or a chest of drawers, or for a sliding door that can slide relative to a structure such as a wall / floor / ceiling in a building.

[0042] Figure 2 FIG. 1 is a perspective view showing a sliding track 100 for a sliding device according to a first embodiment of the present disclosure. The sliding track 100 may be Figure 1The slide track 100-1 or the slide track 100-2 shown in FIG. The slide track 100 includes an elongated rod body 102 having a plurality of walls 104, 106, 108 that form an open channel 110 extending along the longitudinal axis of the slide track 100. Figure 2 In FIG, an elongated rod body 102 is shown having three walls forming a generally U-shaped body. Specifically, a first wall 104 is arranged opposite a second wall 106, the two walls forming a side of the U-shape, and a third wall 108 is arranged between the first wall 104 and the second wall 106, the third wall 108 forming a bottom of the U-shape. Figure 2 In the embodiment of the present invention, the first wall 104 and the second wall 106 are arranged parallel to each other, and the third wall 108 is arranged perpendicular to the first wall 104 and the second wall 106. However, it is contemplated that the walls 104, 106, 108 can be formed with different relative angles, which still form an open channel 110 in the elongated rod body 102. For example, the first wall 104 and the second wall 106 can be inclined inwardly or outwardly, symmetrically or asymmetrically from the third wall 108. In one example, the first wall 104 and the second wall 106 can form a V-shape without the third wall 108. In other examples, there may be more than three walls. For example, an intermediate wall can connect each of the first wall 104 and the second wall 106 to the third wall 108. Therefore, different cross-sections of the sliding track 100 are easily contemplated by those skilled in the art.

[0043] The sliding track 100 further includes at least one flange 112a, 112b. Figure 2 , two flanges 112a, 112b are shown connected to each of the first wall 104 and the second wall 106. The flanges 112a, 112b extend from one side of the elongated rod body 102 substantially away from the open channel 110. That is, the flanges 112a, 112b extend outwardly from the elongated rod body 102. Specifically, the first flange 112a extends from the first wall 104 away from the open channel 110, and the second flange 112b extends from the second wall 106 of the elongated rod body 102 away from the open channel 110 in a direction opposite and parallel to the extension of the first flange 112a. As will be described with respect to Figure 3 4, the flanges 112a, 112b are parallel to the plate on which the sliding rail 100 is mounted, for example, Figure 1 The top surface of the board 200 is shown in FIG.

[0044] exist Figure 2In the embodiment shown in , the first wall 104, the second wall 106 and the third wall 108 are arranged orthogonally (i.e., at right angles to each other), and the extension of the flanges 112a, 112b is substantially located in a plane perpendicular to the first wall 104 and the second wall 106 and parallel to the third wall 108. In other embodiments, the first wall 104 and the second wall 106 may not be perpendicular to the third wall 108. In these embodiments, the arrangement of the flanges 112a, 112b depends on the positioning of the sliding track 100 when it is inserted into the board. For example, if the third wall 108 is not arranged horizontally, the flanges 112a, 112b may extend substantially in a plane perpendicular to the first wall 104 and the second wall 106 but not parallel to the third wall 108. Similarly, if the first wall 104 and the second wall 106 are not arranged vertically, the flanges 112a, 112b may extend substantially in a plane parallel to the third wall 108 but not perpendicular to the first wall 104 and the second wall 106.

[0045] The flanges 112a, 112b may optionally include corresponding inner portions 114a, 114b extending into the channel 110. Once the slide rail is installed, the inner components 114a, 114b may interact with the guide components of the slide device, as will be described with respect to FIGS. Figure 8 described. Figure 2 Two flanges 112a, 112b are shown in FIG. 1 , but it will be appreciated that there may be only a single flange extending from either the first wall 104 or the second wall 106.

[0046] The sliding track 100 further comprises at least one sliding surface 116a to 116c extending parallel to the longitudinal axis of the sliding track 100. The sliding surfaces 116a to 116c are configured to receive a sliding member of a sliding device, as will be explained with respect to FIGS. 4 and 5. The sliding member may be coupled to a sliding barrier, such as Figure 1 The sliding barrier 400, as will be described with respect to Figures 6 to 8 The sliding surfaces 116a-116c are formed as grooves or recesses in the sliding track 100 and extend along the length of the sliding track 100. Forming the sliding surfaces 116a-116c as grooves improves the control of the lateral position of the sliding member relative to the sliding track 100 as the sliding member slides along the sliding track 100. Figure 2 , three sliding surfaces 116a to 116c are shown corresponding to each of the first and second flanges 112a, 112b and the third wall 108. However, it will be understood that, alternatively, there may be only a single sliding surface on the first flange 112a, the second flange 112b or the third wall 108, or two sliding surfaces may be provided on two of these elements.

[0047] The sliding surfaces 116a to 116c may be at least partially coated with a lipophilic composition coating to provide a sliding layer with reduced friction. The lipophilic composition coating may include compounds including C6 to C40, such as C8 to C30 or even C10 to C24, non-aromatic hydrocarbon groups, such as alkenyl and / or alkyl groups, such as alkyl groups. More details of suitable lipophilic compositions are disclosed in WO 2017 / 042201 and WO 2018 / 160127.

[0048] In some embodiments, the sliding rail 100 is formed of plastic, preferably a plastic including a polymer selected from the group of polymers including the following: polyoxymethylene (POM), polymethyl methacrylate (PMMA), polycarbonate (PC), polypropylene (PP), polypropylene copolymer (PPCO), polyester (e.g., thermoplastic polyesters such as polyethylene terephthalate (PET)), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT) and polylactic acid (PLA), as well as bio-based thermoplastic polyesters such as polyhydroxyalkanoates (PHA), polyhydroxybutyrate (PHB) and polyethylene furandicarboxylate (PEF), polyamide (PA), such as polyamide 6 (PA6), polyvinyl chloride (PVC), polyphenylene sulfide (PPS), polyaryletherketone (PAEK), such as polyetheretherketone (PEEK) and polytetrafluoroethylene (PTFE), more preferably, the plastic includes a polymer selected from the group of polymers including PA, PC, PPCO and PMMA. By forming the slide track 100 from plastic rather than metal, the disadvantages associated with metal slide tracks are mitigated. Specifically, plastic slide tracks are lightweight, less rigid, do not require surface treatments such as painting, and are less complicated and inexpensive to manufacture. For example, in some embodiments, the slide track 100 is formed by extrusion molding. In some embodiments, the slide track 100 can be formed by injection molding.

[0049] In other embodiments, the slide track 100 may be formed of a metal, such as aluminum or steel. In these embodiments, at least one of the slide surfaces 116a to 116c may be coated with a paint containing a resin, such as an acrylic resin, having a lipophilic composition such as those discussed above.

[0050] The slide track 100 may be substantially linear to allow linear movement of the slide member along the longitudinal axis of the slide track. In other embodiments, the slide track 100 may have a generally curved form along its longitudinal axis to allow movement along a smooth curve.

[0051] Figure 3 It is shown mounted on a board 200, for example, Figure 1 Plate 200-1 Figure 2 The board 200 may be a fiberboard, such as MDF or HDF, i.e. a particle board (also called chipboard). Figure 3 As seen in FIG. 8 , the elongated rod body 102 is inserted into the recess 202 of the plate 200 .

[0052] When installed in the plate 200, the flanges 112a, 112b are configured to support vertical loads applied to the sliding track 100. In some embodiments, the support surface 118, 118b of each flange 112a, 112b is configured to engage with the plate 200 to support the vertical load. In these embodiments, the bottom surface 118c of the third wall 108 may or may not engage with the plate 200, thereby forming a gap 204 between the bottom surface 118c and the bottom 206 of the recess 202. In some embodiments, the bottom surface 118c of the third wall 108 can support vertical loads applied to the sliding track 100. This ensures free movement of the sliding barrier along the sliding track 100 because no load-bearing contact between the sliding barrier and the sliding track 100 is required elsewhere. In the case where the bottom surface 118c of the third wall 108 is not engaged with the plate 200, the vertical load is supported by the flanges 112a, 112b. This provides tolerance for the depth of the recess 202 and the insertion of the slide rail 100 into the recess 202 of the plate 200. In this way, the recess 202 can be made deep enough to ensure that contact between the slide rail 100 and the plate 200 is made at the bearing surfaces 118a, 118b.

[0053] like Figure 3 As shown in FIG. 1 , the sliding surfaces 116 a to 116 c are formed on the surfaces 120 a to 120 c opposite to the supporting surfaces 118 a to 118 c. Figure 2 and Figure 3 In the orientation of , the sliding surfaces 116a to 116c are formed on the upper surfaces 120a, 120b formed by the first and second flanges 112a, 112b, and the third wall 108. The upper surfaces 120a, 120b of the first and second flanges 112a, 112b can be considered to face in a direction away from the third wall 108 of the elongated rod body 102, and the support surfaces 118a, 118b can be considered to face in a direction toward the third wall 108 of the elongated rod body 102. The upper surface 120c of the third wall 108 can be considered to be a surface of the third wall 108 adjacent to the channel 110. In other words, the support surfaces 118a, 118b can be considered to face the third wall 108, while the surfaces 120a, 120b can be considered to face away from the third wall 108.

[0054] In operation, and as will be Figure 4AAs explained, the channel 110 is configured to receive a guide member of a sliding device. The guide member may be coupled to a sliding barrier, such as Figure 1 The sliding barrier 400. In this way, the guide member is used to keep the sliding barrier in place as it moves along the length of the sliding track 100 and ensure good contact between the sliding member and the associated sliding surface.

[0055] The flanges 112a, 112b each include an inner surface 122a, 122b. The inner surfaces 122a, 122b can be configured to engage with the guide member. This provides improved contact and reduced friction between the guide member and the slide track 100 along the length of the slide track 100. In some embodiments, the inner surface 122a, 122b of at least one flange 112a, 112b can be configured to engage a corresponding leaf-shaped element of the guide member, such as will be described with respect to Figure 4A In some embodiments, the inner surface 122a, 122b of at least one flange 112a, 112b may include a leaf-like element configured to engage a corresponding surface of a guide member, as described with respect to Figure 4B The inner surfaces 122a, 122b may be present on the respective inner portions 114a, 114b of the flanges 112a, 112b, or, if the inner portions 114a, 114b are not present, the inner surfaces 122a, 122b may be a portion of the first wall 104 and the second wall 106.

[0056] The first wall 104 and the second wall 106 may also each include a ridge 124a, 124b disposed on an outer surface of the corresponding wall and extending along the length of the slide track 100. The ridges 124a, 124b are used to increase the friction between the slide track 100 and the plate 200 when the slide track 100 is installed. In particular, when the slide track 100 is installed in the plate 200, the ridges 124a, 124b contact the side surfaces 208, 210 of the recess 202 and resist the slide track 100 from moving out of the recess 202.

[0057] Figure 4A 1 shows a cross-sectional view of a sliding device 300-1 according to a first embodiment. The sliding device 300-1 may be Figure 1 The main sliding device 300-1 shown in FIG. The sliding device 300-1 includes a sliding track 100-1, and the sliding track 100-1 can be connected to Figure 2 and Figure 3 The slide rail 100 shown in FIG. 1 may be the same as that shown in FIG. 1 , or may have some minor differences, as discussed below. The slide device 300 - 1 further includes a slide member 302 - 1 and a guide component 304 - 1 . Figure 4AThe sliding device 300-1 is generally intended for use at the lower portion of a sliding barrier system, as will be described with reference to Figure 6 and Figure 8 Explained in more detail.

[0058] The sliding member 302-1 is configured to contact the sliding surface 116a provided on the first flange 112a of the sliding track 100-1. It will be understood that the sliding member 302-1 can also be configured to contact the sliding surface 116b provided on the second flange 112b of the sliding track 100-1. Similarly, two sliding members 302-1 can be implemented and configured to contact the corresponding sliding surfaces 116a, 116b of the first flange 112a and the second flange 112b. In this embodiment, the sliding surface 116c is not formed on the upper surface 120c of the third wall 108, but it will be understood that such a sliding surface and a corresponding sliding member can exist.

[0059] The sliding member 302-1 is configured to slide along the sliding surface 116a in a direction parallel to the longitudinal axis of the sliding rail 100-1, that is, perpendicular to the longitudinal axis of the sliding rail 100-1. Figure 4A This is Figure 1 The sliding direction A is shown in FIG. The movement may be caused by actuation of the sliding device 300 - 1 and / or the sliding barrier by a user. As discussed above, the sliding surface 116 a may be arranged as a recess in the first flange 112 a and may extend along the sliding track 100 - 1 .

[0060] The sliding member 302-1 and the guide member 304-1 may be coupled to a sliding barrier, such as Figure 1 The sliding barrier 400, as will be described with respect to Figure 6 and Figure 8 For example, the sliding member 302-1 may be provided with fastening means adapted to be connected to the sliding barrier to allow the sliding barrier to move along the longitudinal axis of the sliding track 100-1.

[0061] The sliding member 302-1 may include at least one leaf-shaped element 306 configured to provide contact with the sliding surface 116a. The leaf-shaped element 306 may extend in a sliding direction, that is, in a direction parallel to the longitudinal axis of the sliding track 100-1, for example Figure 1 The sliding direction A shown in FIG. 1 extends. It has been found that the friction is reduced by reducing the contact area at the joint between the sliding track 100-1 and the sliding member 302-1, for example by configuring the part of the sliding member 302-1 arranged to contact the sliding surface 116a as a leaf-shaped element 306. According to one embodiment, the contact area of ​​each individual contact point is less than 3 mm 2 , for example, less than 1.5mm 2or less than 0.75mm 2 The sliding member 302-1 may also be provided with more than one contact point, such as two, three or four contact points. If the sliding member is configured with one or more leaf-shaped elements 306 extending along the sliding direction A, the edge of each leaf-shaped element represents a separate contact point.

[0062] Sliding member 302-1 can be formed by plastic. In one embodiment, sliding member 302-1 is formed by a polymer selected from the group of polymers including the following: polyoxymethylene (POM), polymethyl methacrylate (PMMA), polycarbonate (PC), polypropylene (PP), polypropylene copolymer (PPCO), polyester (e.g. thermoplastic polyester, such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT) and polylactic acid (PLA), and bio-based thermoplastic polyester, such as polyhydroxyalkanoate (PHA), polyhydroxybutyrate (PHB) and polyethylene furandicarboxylate (PEF)), polyamide (PA), such as polyamide 6 (PA6), polyvinyl chloride (PVC), polyphenylene sulfide (PPS), polyaryletherketone (PAEK; e.g. polyetheretherketone (PEEK)) and polytetrafluoroethylene (PTFE). In some embodiments, sliding member 302-1 can be formed by injection molding.

[0063] In some embodiments, the sliding member 302-1 can be formed of a different plastic than the sliding track 100-1. That is, the sliding track 100-1 is formed of a first plastic and the sliding member 302-1 is formed of a second plastic. In some embodiments, only the leaf elements 306 of the sliding member 302-1 are formed of the second plastic. In other embodiments, the entire sliding member 302-1 is formed of the second plastic.

[0064] The first plastic and the second plastic can be plastics of different grades (e.g., PET with different intrinsic viscosities), plastics of different subtypes of plastic (e.g., PA6 and PA66, or PET and PBT), or preferably plastics of different types (e.g., polyacetal and polyamide), i.e., plastics containing different types of polymers. The first plastic can contain a first type of polymer, such as polyoxymethylene (POM), while the second plastic can contain another type of polymer, such as polyamide (PA), polycarbonate (PC), or polyester (PET). In different types of polymers, the linkages between monomers are usually different (e.g., amide coupling and acetal coupling, respectively), and / or the functional groups attached to the polymer chains are different (e.g., amide and methyl, respectively). In one embodiment, the first plastic is PA, PC, PPCO, or PMMA, and the second plastic is POM or PA. In another embodiment, the first plastic is POM or PA. In a preferred embodiment, one of the first plastic and the second plastic is POM, and the other is PA, such as PA6 or PC. In a most preferred embodiment, the first plastic is PA, PC, or PET, and the second plastic is POM.

[0065] The guide member 304-1 is arranged adjacent to and spaced apart from the sliding member 302. The guide member 304-1 is arranged to be received in the open channel 110 of the sliding track 100-1. The guide member 304-1 is configured to extend along the channel 110 in a direction parallel to the longitudinal axis of the sliding track 100-1, for example Figure 1 1. The guide member 304-1 slides in the sliding direction A shown in FIG. The movement may be caused by actuation of the sliding device 300-1 and / or the sliding barrier by a user. As discussed above, the guide member 304-1 is used to hold the sliding barrier in place as the sliding barrier moves along the length of the sliding track 100 and ensure good contact between the sliding member 302-1 and the associated sliding surface 116a. In some embodiments, the guide member 304-1 may be formed of a plastic such as POM.

[0066] like Figure 4AAs shown in , the guide member 304-1 includes leaf-shaped elements 308a, 308b. The leaf-shaped elements 308a, 308b can extend along the sliding direction A and can be configured to engage with the inner surfaces 122a, 122b of the flanges 112a, 112b. In other embodiments, the leaf-shaped elements 308a, 308b can extend perpendicular to the sliding direction A to increase the potential contact area between the leaf-shaped elements 308a, 308b and the inner surfaces 122a, 122b of the flanges 112a, 112b. In some embodiments, the inner surfaces 122a, 122b can each include a groove configured to receive the corresponding leaf-shaped elements 308a, 308b. This provides improved contact between the guide member 304-1 and the slide track 100-1 along the length of the slide track 100-1, allowing the slide barrier to be held in place as it moves along the length of the slide track 100-1, and allowing good contact to be formed between the slide member 302 and the slide surface 116a.

[0067] Figure 4B Shown with Figure 4A , except that the leaf-shaped elements 308a, 308b are disposed on the inner surfaces 122a, 122b (not shown) of the flanges 112a, 112b. In such an embodiment, the guide member 304-1 may include grooves configured to receive the corresponding leaf-shaped elements 308a, 308b.

[0068] In this embodiment, the first wall 104 and the second wall 106 each include a plurality of ridges 124a, 124b disposed on the outer surface of the corresponding wall and extending along the length of the sliding track 100-1. By providing a plurality of ridges 124a, 124b, the friction between the sliding track 100-1 and the plate 200 is further increased when the sliding track 100-1 is installed.

[0069] Figure 5B 2 shows a cross-sectional view of a sliding device according to a second embodiment. The sliding device 300-2 may be Figure 1 The auxiliary sliding device 300-2 shown in FIG. The sliding device 300-2 includes a sliding rail 100-2, and the sliding rail 100-2 can be connected to Figure 1 The slide rails 100, 100-1 shown in Figure 4 may be the same, or may have some minor differences, as discussed below. The slide device 300-2 also includes a slide member 302-2 and a guide component 304-2. Figure 5A The sliding device 300-2 is with Figure 4A The sliding device is shown in the opposite way. That is, Figure 5A The sliding device 300-2 is relative to Figure 4AThe slide is shown upside down. This is because Figure 5A The sliding device 300-2 is generally intended for use at the upper portion of a sliding barrier system. Figure 7 and Figure 8 For a more detailed explanation.

[0070] exist Figure 5A , the sliding member 302-2 is configured to contact the sliding surface 116c of the sliding track 100 provided on the third wall 108 of the sliding track 100-2. The sliding surface 116c is provided on the lower surface 120c of the third wall 108 and may be arranged as a groove extending along the sliding track 100-2 in the third wall 108. In this embodiment, the sliding surfaces 116a, 116b are not formed on the surfaces 120a, 120b of the first flange 112a and the second flange 112b, but it will be understood that such sliding surfaces and corresponding sliding members may be present.

[0071] In this embodiment, the sliding member 302-2 and the guide member 304-2 are connected to each other or integrated into a single piece. For example, the sliding member 302-2 and the guide member 304-2 can be held together in a common housing, for example as part of a guide device. The sliding member 302-2 and the guide member 304-2 can be formed as a single structure, or as two separate but connected structures. The sliding member 302-2 and the guide member 304-2 are arranged in the channel 110 of the sliding track 100-2. The sliding member 302-2 is configured to contact the sliding surface 116c and move along the sliding surface 116c in a direction parallel to the longitudinal axis of the sliding track 100-2, that is, perpendicular to the sliding surface 116c. Figure 5A The direction of the plane, for example Figure 1 In this way, the sliding member 302-2 and the guide member 304-2 are configured to slide along the channel 110 in a direction parallel to the longitudinal axis of the sliding track 100-2. Figure 4A In the embodiment of FIG. 1 , the sliding member 302 - 2 may include at least one leaf-shaped element 306 configured to provide contact with the sliding surface 116 c .

[0072] It has been found that when the contact pressure between the sliding member and the sliding track is not too low, the friction becomes lower. Thus, the sliding member 302-2 of this embodiment can be configured to apply a spring force to the sliding surface 116c. In particular, the sliding member 302-2 or the guide member 304-2 can include an elastic member 310 or be coupled to an elastic member 310, such as Figure 5ASchematically illustrated in the spring, the elastic component 310 makes it possible to limit the movement of the sliding member 302-2 perpendicular to the extension of the sliding track 100-2. In this way, when the sliding member 302-2 is installed in the sliding track 100-2, the contact between the sliding member 302-2 and the sliding surface 116c will cause the elastic component 310 to be compressed. This causes the elastic component 310 to be loaded and push the sliding member 302-2 against the sliding surface 116c, which means that there is always contact between the sliding member 302-2 and the sliding surface 116c, and the sliding member 302-2 applies a specific load such as caused by the spring 310 on the sliding surface 116c. This plays the role of keeping the sliding member 302-2 in place, and increases the contact pressure between the sliding member 302-2 and the sliding surface 116c, thereby reducing friction and providing low starting resistance. This combination is difficult to achieve for rolling bearings and other bearings known in the art.

[0073] and Figure 4A Similar to the embodiment shown in , the guide member 304-2 includes leaf-shaped elements 308a, 308b, which extend along the sliding direction A and are configured to engage with the inner surfaces 122a, 122b of the flanges 112a, 112b. In some embodiments, the leaf-shaped elements 308a, 308b can extend perpendicular to the sliding direction A. In some embodiments, the inner surfaces 122a, 122b can each include a groove configured to receive the corresponding leaf-shaped element 308a, 308b. This provides the related advantages discussed above.

[0074] Figure 5B Shown with Figure 5A 00-1 is a cross-sectional view of a sliding device 300-1 that is substantially similar to the second embodiment shown in , except that the leaf-like elements 308a, 308b are arranged on the inner surfaces 122a, 122b (not shown) of the flanges 112a, 112b, and the guide member 304-2 may include grooves configured to receive the corresponding leaf-like elements 308a, 308b.

[0075] In this embodiment, the first wall 104 and the second wall 106 each include a plurality of ridges 124a, 124b disposed on the outer surface of the corresponding wall and extending along the length of the sliding track 100-2. By providing a plurality of ridges 124a, 124b, the friction between the sliding track 100-2 and the plate 200 is further increased when the sliding track 100-2 is installed.

[0076] Figure 6 Shown include Figure 4A4 is a cross-sectional view of the lower end of the first sliding barrier system 10 of the first sliding device 300-1 and the sliding barrier 400. The sliding track 100-1 is mounted on the lower plate or base plate 200-1. The sliding track 100-1 can be fixed in the lower plate 200-1 by a friction fit caused by the first wall 104 and the second wall 106 of the sliding track 100-1 being compressed inwardly when installed.

[0077] The sliding barrier 400 is arranged upright on the sliding track 100-1. In particular, the sliding barrier 400 is connected to the sliding member 302-1 of the sliding device 300-1. The sliding member 302-1 is in contact with the sliding surface 116a. As discussed above, the sliding member 302-1 is configured to slide along the sliding surface 116a in a direction parallel to the longitudinal axis of the first sliding track 100-1, that is, perpendicular to the sliding surface 116a. Figure 6 The direction of the plane, for example Figure 1 Slide in the sliding direction A shown in .

[0078] The guide member 304-1 is arranged in the channel 110 of the sliding track 100-1. The guide member 304-1 is used to keep the sliding barrier 400 in place as the sliding barrier 400 moves along the length of the sliding track 100-1 and ensure good contact between the sliding member 302-1 and the sliding surface 116a. When the guide member 304-1 is present, the sliding barrier 400 can be connected to the guide member 304-1. The sliding member 302-1 and / or the guide member 304-1 can be provided with a fastening device (not shown) suitable for connecting to the sliding barrier 400.

[0079] exist Figure 6 In the embodiment of the present invention, the sliding track 100-1 and the sliding device 300-1 are arranged at the lower part of the sliding barrier system 10. The sliding track 100 is arranged so that the sliding surfaces 116a, 116b face upward. That is, the sliding surfaces 116a, 116b are respectively provided on the upper surfaces 120a, 120b of the first flange 112a and the second flange 112b.

[0080] As discussed above, the first and second flanges 112a, 112b are configured to support vertical loads applied to the sliding barrier system 10. To this end, the lower surfaces 118a, 118b of the first and second flanges 112a, 112b are configured to engage the panel 200-1.

[0081] Figure 7 Shown include Figure 5A2 is a cross-sectional view of an upper end portion of a first sliding barrier system 10 of a sliding device 300-2 and a sliding barrier 400. The sliding rail 100-2 is installed in the upper plate 200-2 and is arranged in an opposite manner to the first sliding rail 100-1, i.e., upside down relative to the first sliding rail 100-1. The sliding rail 100-2 can be fixed in the upper plate 200-2 by friction fit. The sliding barrier 400 is connected to the sliding member 302-2 and the guide component 304-2 of the sliding device 300-2, as discussed above, the sliding member 302-2 and the guide component 304-2 can be coupled or integrated with each other.

[0082] exist Figure 7 In the embodiment of the present invention, the sliding track 100-2 and the sliding device 300-2 are arranged at the upper portion of the sliding barrier system 10. The sliding track 100 is arranged so that the sliding surface 116c faces downward. That is, the sliding surface 116c is provided on the lower surface 120c of the third wall 108 adjacent to the channel 110.

[0083] The sliding member 302-2 contacts the sliding surface 116c of the sliding rail 100-2. As discussed above, the sliding member 302-2 is configured to slide along the sliding surface 116c in a direction parallel to the longitudinal axis of the second sliding rail 100-2, that is, perpendicular to the sliding surface 116c. Figure 7 The direction of the plane, for example Figure 1 Slide in the sliding direction A shown in .

[0084] As discussed above, the sliding member 302-2 and the guide component 304-2 can be coupled or integrated with each other. The sliding member 302-2 and the guide component 304-2 can be formed as a single structure, or formed as two separate but connected structures. The guide component 304-2 is arranged in the channel 110 of the sliding track 100-2, and the sliding member 302-2 is configured to contact the sliding surface 116c and slide along the sliding surface 116c. The sliding member 302-2 may include an elastic component 310 and is configured to apply a spring force to the sliding surface 116c, as discussed above.

[0085] Figure 8 4 shows a cross-sectional view of a first sliding barrier system 10, the first sliding barrier system 10 includes sliding devices 300-1, 300-2 arranged at the bottom and top of a sliding barrier 400, respectively. Figure 6 and Figure 7 as shown in .

[0086] Typically, if the door is to be arranged vertically, the first sliding track 100-1 and the second sliding track 100-2 are aligned horizontally. However, the door may also be arranged in an inclined configuration, in which case the first sliding track 100-1 and the second sliding track 100-2 are not aligned.

[0087] The sliding barrier 400 is connected to the first sliding member 302-1 and the second sliding member 302-2. In this way, when the sliding barrier 400 is actuated, the sliding members 302-1, 302-2 slide along the sliding rails 100-1, 100-2 in a direction parallel to the longitudinal axis of the sliding rails 100-1, 100-2, that is, in the sliding direction A.

[0088] Fig. 9 FIG. 1 shows a perspective view of a second sliding barrier system 1010. The sliding barrier system 1010 and Figure 1 The sliding barrier system 10 shown in FIG. 1 is similar to the sliding barrier system 10 shown in FIG. 1 , except that the sliding barrier system 1010 includes two sliding barriers 1400a, 1400b, a first main slide 1014a and a second main slide 1014b, and a first secondary slide 1016a and a second secondary slide 1016b. The first sliding barrier 1400a and the second sliding barrier 1400b are arranged adjacent to each other and parallel to each other. Each of the main slide 1014 and the secondary slide 1016 is provided by a double sliding track 1100, as will be explained below.

[0089] The first and second main slides 1014 are arranged at the lower end of the sliding barrier system 1010 and are adapted to support the weight of the sliding barrier 1400. Specifically, the first main slide 1014a is adapted to support the weight of the first sliding barrier 1400a, and the second main slide 1014b is adapted to support the weight of the second sliding barrier 1400b.

[0090] The first and second secondary slides 1016 are arranged at the upper end of the sliding barrier system 1010 and are adapted to manipulate the sliding barrier 1400 during the sliding movement defined by the main slide 1014. Specifically, the first secondary slide 1016a is adapted to manipulate the first sliding barrier 1400a, and the second secondary slide 1016b is adapted to manipulate the second sliding barrier 1400b.

[0091] The first double slide track 1100-1 is adapted to provide the first and second main slide devices 1014, as will be described with reference to Figures 10 to 12 The first double sliding track 1100 - 1 is adapted to be rigidly connected to the lower platform 1200 - 1 in a concave configuration so that the sliding barrier 1400 can move relative to the lower platform 1200 - 1 . The first double sliding track 1100 - 1 is adapted to support the weight of the sliding barrier 1400 .

[0092] The second double sliding track 1100-2 is adapted to provide the first and second secondary sliding devices 1016. The second double sliding track 1100-2 is adapted to be rigidly connected to the upper platform 1200-2 in a concave configuration so that the sliding barrier 1400 can move relative to the upper platform 1200-2. The sliding barrier 1400 is configured to slide along the sliding track 1100 along the sliding direction A' relative to the platform 1200.

[0093] Each of the lower platform 1200-1 and the upper platform 1200-2 forms part of a piece of furniture, in this case a lower panel and an upper panel of a wardrobe. The sliding barrier system 1010 may alternatively be arranged in a cabinet, a cupboard, a sideboard or a chest of drawers, or for a sliding door that can slide relative to a structure such as a wall / floor / ceiling in a building.

[0094] Fig.10 FIG. 1 is a cross-sectional view of a slide rail 1100 of a slide device according to a second embodiment. The slide rail 1100 may be Fig. 9 1 and 11. The sliding track 1100-1 or the sliding track 1100-2 shown in FIG. Similar to the sliding track 100 of the first embodiment, the sliding track 1100 includes an elongated rod body 1102 having a plurality of walls. The sliding track 1100 may be substantially linear to allow the sliding member to move linearly along the longitudinal axis of the sliding track 1100. In other embodiments, the sliding track 1100 may have a generally curved form along its longitudinal axis to allow movement along a smooth curve.

[0095] In this case, the sliding track 1100 includes a first wall 1104, a second wall 1106, a third wall 1108, and a fourth wall 1114 that form two open channels 1110a, 1110b extending along the longitudinal axis of the sliding track 1100. The open channels 1110a, 1110b are configured to receive sliding members of a sliding device, such as will be described with reference to FIG. Fig.12 As explained in the slide rail 100, the first wall 1104 is arranged opposite to the second wall 1106, and the third wall 1108 is arranged between the first wall 1104 and the second wall 1106 and connects the first wall 1104 and the second wall 1106. The fourth wall 1114 extends from the third wall 1108 between the first wall 1104 and the second wall 1106, and extends in a direction parallel to the first wall 1104 and the second wall 1106, for example Fig. 9 This forms two open channels: a first open channel 1110a between the first wall 1104 and the fourth wall 1114, and a second open channel 1110b between the fourth wall 1114 and the second wall 1106. The third wall 1108 forms the bottom of the two channels 1110a, 1110b.

[0096] exist Fig.10 In the embodiment of the present invention, the first wall 1104, the second wall 1106 and the fourth wall 1114 are arranged parallel to each other, and the third wall 1108 is arranged perpendicular to the first wall 1104, the second wall 1106 and the fourth wall 1114. However, it will be envisioned that multiple walls can be formed with different relative angles while still forming two open channels 1110a, 1110b in the elongated rod body 1102. For example, any of the first wall 1104 and the second wall 1106 can be tilted inwardly or outwardly, symmetrically or asymmetrically from the third wall 1108. In one example, there can be more than four walls. For example, an intermediate wall can connect each of the first wall 1104 and the second wall 1106 to the third wall 1108. Therefore, those skilled in the art can easily envision different cross-sections of the sliding track 1100.

[0097] Similar to the sliding track 100, the sliding track 1100 further includes at least one flange 1112a, 1112b. Fig.10 , two flanges 1112a, 1112b are shown connected to the first wall 1104 and the second wall 1106, respectively. The flanges 1112a, 1112b extend from one side of the elongated rod body 1102 substantially away from each open channel 1110a, 1110b. That is, the flanges 1112a, 1112b extend outwardly from the elongated rod body 1102. Specifically, the first flange 1112a extends from the first wall 1104 away from the first open channel 1110, and the second flange 1112b extends from the second wall 1106 of the elongated rod body 1102 away from the second open channel 1110b in a direction opposite and parallel to the extension of the first flange 1112a. As will be described with respect to Fig.12 As explained, the flanges 1112 a , 1112 b are parallel to the top surface of the plate 1200 to which the sliding rail 1100 is mounted.

[0098] exist Fig.10In the embodiment shown in , the walls 1104, 1106, 1108, 1114 are arranged orthogonally (i.e., at right angles to each other), and the flanges 1112a, 1112b extend substantially in a plane that is perpendicular to the first wall 1104, the second wall 1106, and the fourth wall 1114 and parallel to the third wall 1108. As discussed above, in some embodiments, the first wall 1104, the second wall 1106, and the fourth wall 1114 may not be perpendicular to the third wall 1108. In these embodiments, the arrangement of the flanges 1112a, 1112b depends on the positioning of the sliding track 1100 when the sliding track 1100 is inserted into the board. For example, if the third wall 1108 is not arranged horizontally, the flanges 1112a, 1112b may extend substantially in a plane that is perpendicular to the first wall 1104 and the second wall 1106 but not parallel to the third wall 1108. Similarly, if the first wall 1104 and the second wall 1106 are not arranged vertically, the flanges 1112a, 1112b may extend substantially in a plane parallel to the third wall 1108 but not perpendicular to the first wall 1104 and the second wall 1106.

[0099] The sliding track 1100 also includes at least one sliding surface 1116a, 1116b parallel to the longitudinal axis of the sliding track 1100 and extending along the length of the sliding track 1100. The sliding surfaces 1116a, 1116b are formed on the top surface 1120 of the third wall 1108 and are configured to receive a sliding member of a sliding device, such as the sliding member of the sliding device 1108. Fig.11 and Fig.12 The sliding member may be coupled to the sliding barrier as will be explained with respect to Fig.12 As explained. The sliding surfaces 1116a, 1116b are formed as grooves in the sliding track 1100. In this embodiment, the sliding surfaces 1116a, 1116b are formed into a shallow V-shape, which further improves the control of the lateral position of the sliding member relative to the sliding track 1100 when the sliding member slides along the sliding track 1100. In other embodiments, the sliding surfaces 1116a, 1116b can be formed into a U-shape. In other embodiments, the sliding surfaces 1116a, 1116b can be formed as flat surfaces including grooves, as discussed with respect to the sliding surfaces 116a to 116c. Fig.10, two sliding surfaces 1116a, 1116b are shown at the bottom of each channel 1110a, 1110b. However, it will be understood that, alternatively, there may be only a single sliding surface in the first channel 1110a or the second channel 1110b. Additional sliding surfaces corresponding to each of the first flange 1112a and the second flange 1112b may also be formed. The sliding surfaces 1116a, 1116b may be at least partially coated with a lipophilic composition coating to provide a sliding layer with reduced friction, as discussed with respect to the sliding track 100.

[0100] In some embodiments, the slide track 1100 is formed of a plastic, such as one of the plastics discussed with respect to the slide track 100. In some embodiments, the slide track 1100 is formed by extrusion molding or injection molding. In other embodiments, the slide track 1100 can be formed of a metal, such as aluminum or steel. In these embodiments, at least one sliding surface 1116a, 1116b can be coated with a paint containing a resin, such as an acrylic resin, having a lipophilic composition such as those discussed above.

[0101] Fig.11 A cross-sectional view of a sliding member 1300 for use with the sliding track 1100 is shown. The sliding member 1300 includes an elongated rod body 1302 having a plurality of walls 1304, 1306, 1308 that form an open channel 1310 extending along the longitudinal axis of the sliding member 1300. The open channel 1310 is configured to receive a sliding barrier, such as a sliding barrier, as described with reference to FIG. Fig.12 The sliding member 1300 , when inserted into the sliding track 1100 , can provide a sliding device, such as one of the main sliding device 1014 or the auxiliary sliding device 1016 .

[0102] exist Fig.11 , an elongated rod body 1302 is shown having three walls forming a generally U-shaped body. Specifically, a first wall 1304 is arranged opposite a second wall 1306, the two walls forming a side of the U-shape, and a third wall 1308 is arranged between the first wall 1304 and the second wall 1306, the third wall 1308 forming the bottom of the U-shape. Fig.12 As explained, the elongated rod body 1302 has a profile configured to match the profile of the slide track 1100 into which the slide member 1300 is to be inserted.

[0103] exist Fig.11In an embodiment, the first wall 1304 and the second wall 1306 are arranged parallel to each other, and the third wall 1308 is arranged perpendicular to the first wall 1304 and the second wall 1306. However, it is contemplated that the walls 1304, 1306, 1308 can be formed with different relative angles while still forming an open channel 1310 in the elongated rod body 1302. For example, the first wall 1304 and the second wall 1306 can be inclined inwardly or outwardly, symmetrically or asymmetrically from the third wall 1308. In one example, there can be more than three walls. For example, an intermediate wall can connect each of the first wall 1304 and the second wall 1306 to the third wall 1308. Therefore, different cross-sections of the sliding track 100 are easily contemplated by those skilled in the art.

[0104] The sliding member 1300 also includes at least one contact portion 1312 extending parallel to the longitudinal axis of the sliding track 1300. The contact portion 1312 is formed on a lower surface 1314 of the third wall 1308 of the sliding member 1300. The contact portion 1312 is configured to engage with the corresponding sliding surfaces 1116a, 1116b of the sliding track 1100, as described with reference to FIG. Fig.12 As explained. In particular, the contact portion 1312 is configured to provide an edge or leaf contact (which appears as a point contact in the illustrated cross section) with the corresponding sliding surfaces 1116a, 1116b of the sliding track 1100. The lower surface 1314 can be formed into a shallow V-shape or a U-shape so that the sliding member 1300 fits in one of the open channels 1110a, 1110b of the sliding track 1100. In particular, the lower surface 1314 has a shape that is steeper than the sliding surfaces 1116a, 1116b of the sliding track 1100. In other embodiments, the lower surface 1314 can have any shape that allows the contact portion 1312 to form an edge or leaf contact with the sliding surfaces 11116a, 1116b and allows the sliding member 1300 to move freely in the longitudinal direction in the open channels 1110a, 1110b.

[0105] The first wall 1304 and the second wall 1306 of the sliding member 1300 may also each include leaf-shaped elements 1316a, 1316b disposed on the outer surface of the respective wall and extending along the length of the sliding member 1300. The leaf-shaped elements 1316a, 1316b are configured to engage corresponding surfaces of the open channels 1110a, 1110b of the sliding track 1100, as will be described with reference to FIG. Fig.12 Explained.

[0106] The sliding member 1300 can be formed of a plastic, similar to the sliding member 302 discussed above. In some embodiments, the sliding member 1300 can be formed of a different plastic than the sliding track 1100. That is, the sliding track 1100 is formed of a first plastic and the sliding member 1300 is formed of a second plastic. The sliding member 1300 can include one or more stops (not shown) disposed in the open channel 1310, the one or more stops being configured to resist longitudinal movement of a sliding barrier mounted in the sliding member.

[0107] Fig.12 1 shows a cross-sectional view of the lower part of the second sliding barrier system 1010. In the second sliding barrier system 1010, the sliding rail 1100-1 is installed in the lower plate 1200-1, which can be a fiberboard, such as MDF or HDF, or a particle board (also called chipboard). Fig.12 As seen in FIG. 1 , the sliding rail 1100 - 1 is inserted into the recess 1202 of the plate 1200 - 1 .

[0108] When installed in the plate 1200-1, the flanges 1112a, 1112b are configured to support the vertical load applied to the sliding track 1100-1. In some embodiments, the support surfaces 1118, 1118b of each flange 1112a, 1112b are configured to engage with the plate 1200-1 to support the vertical load. In these embodiments, the bottom surface 1118c of the third wall 1108 may not engage with the plate 1200-1, thereby forming a gap 1204 between the bottom surface 1118c and the bottom 1206 of the recess 1202. This provides tolerance for the depth of the recess 1202 and the insertion of the sliding track 1100-1 into the recess 1202 of the plate 1200-1. In this way, the recess 1202 can be made deep enough to ensure that the contact between the sliding track 1100-1 and the plate 1200-1 is carried out at the support surfaces 1118a, 1118b.

[0109] Fig.121. Also shown are two sliding members 1300a, 1300b coupled to respective sliding barriers 1400a, 1400b. The sliding members 1300a, 1300b are disposed in respective open channels 1110a, 1110b of the sliding track 1100-1 to provide a first main slide 1014a and a second main slide 1014b. The contact portions 1312a, 1312b of the sliding members 1300a, 1300b engage with respective sliding surfaces 1116a, 1116b of the sliding track 1100-1. Furthermore, the leaf elements 1316a, 1316b of the sliding members 1300a, 1300b engage with respective surfaces of the open channels 1110a, 1110b of the sliding track 1100-1. In this way, the sliding barrier 1400 is held in place as it moves along the length of the sliding track 1100-1 and ensures good edge or leaf contact between the contact portions 1312a, 1312b of the sliding members 1300a, 1300b and the sliding surfaces 1116a, 1116b of the sliding track 1100-1.

[0110] When the sliding barriers 1400a, 1400b are actuated, the sliding members 1300a, 1300b slide along the sliding surfaces 1116a, 1116c in a direction parallel to the longitudinal axis of the sliding track 1100-1, ie in the sliding direction A'. This provides a sliding arrangement for thin and / or multi-component barriers.

[0111] It will be appreciated that a similar arrangement may be provided at the top end of the sliding barrier system 1010, wherein the sliding track 1100-2 is mounted in the upper plate 1200-2. Alternatively, the sliding members 1300a, 1300b may include elastic elements, such as with respect to Figure 5A and Figure 5B In some embodiments, the elastic element may act vertically and / or laterally to ensure contact between the sliding members 1300a, 1300b and the sliding track 1100-2. Alternatively, the sliding track 1100-2 may only provide lateral support for the sliding members 1300a, 1300b at the top end of the sliding barrier system 1010. In some embodiments, the sliding members at the top end of the sliding barrier system 1010 may contact the sliding members 1300a, 1300b with or without the elastic element. Figure 5A and Figure 5B The sliding member shown in is similar.
