Description

Technical Field

[0001] The invention relates to a pull-out guide device with a synchronization mechanism and a damping mechanism. Background Art

[0002] Cabinets with pull-out furniture parts are used in a wide range of applications, for example in workshops and other operating facilities, in the catering industry, in shopfitting, in domestic kitchens, and in laboratories. Depending on the area of ​​application, these pull-out furniture parts are subject to varying requirements, for example with regard to material, chemical and physical properties, operating temperature, or hygiene. However, in all cases, they are connected to the cabinet body via pull-out guides arranged laterally thereon, allowing them to be moved relative to the body.

[0003] This pull-out guide device comprises a body rail that can be mounted on the furniture carcass, a pull-out rail that can be mounted on the pull-out furniture component (drawer), and an intermediate rail located between the two. The body rail and the pull-out rail each have one or more tracks on which rollers roll during use. These rollers are preferably all arranged on the intermediate rail, in particular as upper and lower rollers, which contact corresponding distribution tracks of the body rail and the pull-out rail. The rollers and tracks allow the positions of the three rails to be changed relative to one another, thereby changing the position of the drawer relative to the furniture carcass.

[0004] In other words, the rollers are used to move the extension guides along the extension path in the extension direction from a closed position to an open position. The closed position of the extension guides is when the extension guides are completely pushed together; the open position is when the extension guides are completely pulled apart. Both positions are end positions, where the extension or retraction path is limited by a stop element on the guide rail.

[0005] The center rail can have load-transmitting differential rollers, by means of which the center rail is moved synchronously with the extension rail, wherein the center rail each covers half the distance of the extension rail.

[0006] Extension guides of this type usually have an end position damping unit, with which a drawer movement initiated by a user is damped in the region of one of its end positions and in particular takes place automatically and therefore gently.

[0007] This type of pull-out guide is known from DE 10 2013 101 358 A1. In this known pull-out guide, which consists of a body rail, an intermediate rail, and a pull-out rail, and includes an end position damping unit, the end position damping unit is arranged on the intermediate rail and alternately engages with an actuator on the pull-out rail and an actuator on the body rail at each end position of the pull-out guide. This allows both the closing and opening movements of the pull-out guide to be damped by a single end position damping unit. In this known pull-out guide, the body rail is C-shaped in cross-section, with the opening of the C pointing generally toward the drawer side wall. The body rail is fixed to the body at an L-shaped angle. The intermediate rail runs within the body rail, and the pull-out rail runs on its top surface facing away from the body rail. Thus, in the installed position, the body rail and the pull-out rail are vertically spaced apart by the intermediate rail. A pair of horizontally opposed known pull-out guides accommodates a drawer between them.

[0008] This known guide device also features a synchronization mechanism that synchronizes the movement of the main body rail relative to the intermediate rail and the intermediate rail relative to the pull-out rail. This synchronization mechanism consists of two rollers arranged on the intermediate rail and a belt surrounding the rollers, which is connected to the main body rail and the pull-out rail. This synchronization mechanism prevents the pull-out rail sections from slipping relative to each other during relative movement. This slippage always occurs when the static friction force on the pull-out guide, when loaded, exceeds the applied force. In this case, the pull-out rail and the intermediate rail move together relative to the main body rail while maintaining a fixed position. Consequently, this slippage prevents the pull-out guide from fully closing because the pull-out rail does not move to the closed position due to the lack of movement relative to the intermediate rail.

[0009] The disadvantage of the above-mentioned prior art is that it is only suitable for relatively small drawer loads. In addition, the drawers - i.e. the pull-out furniture parts - must be located between guides, which is not suitable for upright cabinets (medicine cabinets) characterized by narrow, tall shapes and many compartments. Summary of the Invention

[0010] The object of the present invention is therefore to provide a pull-out guide with a synchronization mechanism and a damping mechanism, which is easy to install, can withstand heavy loads and is therefore particularly suitable for pull-outs of upright cabinets, such as medicine cabinets, in which the entire load is located on a pull-out rail mounted below the pull-out.

[0011] This object is achieved by a pull-out guide device for a vertical cabinet, comprising a body rail, an intermediate rail and a pull-out rail, wherein the pull-out rail is movably accommodated in the intermediate rail, and the intermediate rail is in turn movably accommodated in the body rail, wherein the body rail is essentially C-shaped in cross section, with two free side legs and a base connecting the two free side legs, wherein the free ends of the free side legs are bent toward each other, and wherein the body rail has a track for rollers of the intermediate rail, wherein the intermediate rail has two side walls that are spaced apart from each other by means of at least two spacers and are essentially parallel to each other, wherein each side wall has a roller, wherein the pull-out rail is essentially C-shaped in cross section, The invention also provides a sliding panel which is arranged on a pair of sliding panels, the sliding panel also being able to move about the sliding panel when the extension is in motion. The sliding panel also being able to move about the sliding panel when the extension is in motion.

[0012] In the operating position, this pull-out guide is located on the upward-facing side of the base, and therefore also below the sliding door of the vertical cabinet, so that its entire weight rests on the pull-out guide according to the invention. The dynamic load-bearing capacity of such a pull-out guide is typically 75 kg or more and can in particular be up to 350 kg. Above the sliding door, and therefore vertically spaced apart from the pull-out guide, an upper guide is typically arranged—in particular, also in a different configuration—which separates the sliding door from the upper part of the base and guides it along its top surface. Such vertical cabinets can be up to 2.5 meters high, with the sliding door being up to 60 cm wide and the pull-out path up to 1.5 meters.

[0013] In order to meet these dimensions and weights, the pull-out guide is constructed as described with guide rails which are arranged in a nested manner and guide each other, wherein the body rail, as the widest of the three guide rails of the pull-out guide, accommodates the middle rail, which in turn accommodates the pull-out guide, so that the pull-out guide according to the invention is constructed as a nested guide rail set.

[0014] The present invention offers the significant advantage of preventing slippage, which is particularly prone to occur during heavy-duty use, thereby permanently ensuring the correct closing of the sliding door. The rope looped around the guide roller for this purpose is either initially provided as a closed loop, or as a rope strand whose ends are connected to form a loop during installation via another component (e.g., a connector described below), or as a rope strand whose open ends are each secured to one of the main body rail and the extension rail. It is also in accordance with the present invention for the rope to be hooked or pressed into the main body rail.

[0015] The invention also achieves particularly reliable damping of the movement of the extension guide when it is moved into its two end positions by providing a damping unit and arranging two actuators on the carcass rail. These actuators are preferably profiles formed from the profile of the carcass rail, but can also be designed as plastic parts or clamps mounted on the carcass rail.

[0016] It is particularly advantageous here that damping and synchronization have a synergistic effect: the force applied by the user is introduced into the drawer profile, transmitted via the cable of the synchronization mechanism to the intermediate rail, and from there to the damping unit, and from this to the body rail, where the movement is not only synchronized but also damped.

[0017] In a further development of the present invention, each of the two spacers has a guide roller, in particular in the form of a fitted, in particular, one-piece sleeve. Preferably, the other spacer has a rope guide. The spacer, which is necessarily present, additionally serves as a location for the guide rollers of the synchronization mechanism, simplifying the design and production of the pull-out guide. The guide rollers are designed to reliably guide the rope laterally and are therefore preferably designed as sheaves, with recesses formed as V-, U-, or C-shaped grooves. The design is further simplified by the guide rollers being constructed on a, in particular, one-piece sleeve that slides onto and rotatably attaches to the spacer. The inner diameter of the sleeve is therefore selected to be larger than the outer diameter of the spacer, with clearance, and both the spacer and the sleeve are preferably cylindrical. The guide rollers are preferably made of a plastic material, in particular a reinforced, especially fiber-reinforced, and / or wear-resistant plastic material. Alternatively, the sleeve with the guide rollers can be constructed in three or two parts, in particular split along the axis.

[0018] In one embodiment of the present invention, a first connecting member is detachably fixed to the main body guide rail between the guide rollers, and a second connecting member is detachably fixed to the pull-out guide rail behind the guide rollers in the direction of the end of the pull-out guide rail. This detachable connection makes it easy to install the rope when assembling the pull-out guide device, in particular by snapping the two connecting members into the corresponding grooves / brackets of the above-mentioned guide rails. The described arrangement of the rope fixing points allows the intermediate guide rail and the pull-out guide rail to achieve synchronous movement over the entire movement path, both in the pull-out direction and in the retraction direction. Alternatively, in a further development of the present invention, the rope is directly connected to the stop. In this case, the rope is either pressed in there or a safety piece is provided to prevent the rope from escaping upwards from the rope guide device.

[0019] In a further development of the present invention, the damping unit has two independently tightenable and releaseable swivel locks, particularly arranged one behind the other along the axis. This advantageously allows the damping unit to be actuated from both ends: during the closing movement toward the closed position, via the rear actuator on the body rail, and during the extension movement toward the open position, via the front actuator on the extension rail. A spring for both directions of movement is provided between the two actuators. This has the advantage that the spring is longer, thus having a longer service life, and only one spring is required, thus advantageously reducing the number of components. Alternatively, two springs are also suitable for the present invention; these springs then have half the spring travel.

[0020] In a further development of the invention, a further structural simplification is achieved with considerable advantage by making the side walls of the central guide rail identical. This also simplifies inventory management and the supply of spare parts. Identical parts include, in particular, dimensions, material thickness, material, roller guides, bracket openings, and fastening openings.

[0021] Finally, in a further development of the invention, the intermediate guide rail has differential rollers.

[0022] In a further development of the present invention, the connecting piece for fixing the rope is simultaneously provided as a damping stop for the movement of the intermediate guide rail, thus having a dual function. This simplifies the structure and saves costs.

[0023] The present invention further relates to a method for installing a pull-out guide device as described above, comprising the following steps: providing a main body guide rail, providing a pull-out guide rail, assembling an intermediate guide rail, and assembling the main body guide rail, the intermediate guide rail and the pull-out guide rail into a pull-out guide device, wherein assembling the intermediate guide rail comprises the following steps: connecting at least two spacers to the first side wall of the intermediate guide rail, and respectively putting sleeves with guide rollers on the spacers, connecting the rollers to the first and second side walls of the intermediate guide rail, pulling the surrounding rope onto the guide rollers, assembling the two side walls (14, 14'), and wherein assembling the three guide rails comprises the following steps: introducing the intermediate guide rail into the main body guide rail and fixing the rope on the main body guide rail, and then introducing the pull-out guide rail into the intermediate guide rail and fixing the rope on the pull-out guide rail, or introducing the pull-out guide rail into the intermediate guide rail and fixing the rope on the pull-out guide rail, and then introducing the pull-out guide rail and the intermediate guide rail into the main body guide rail and fixing the rope on the main body guide rail.

[0067] Figure 1A perspective view of the pull-out guide 1 in the open position is shown. The body rail 2 forms the largest of the three overlapping rails of the pull-out guide 1 and, in the installed position, is the lowest one. On the left side of the body rail 2, which is essentially C-shaped in cross section, a fastening opening 29 in the base plate 7 can be seen. The free ends 8, 9 of the free legs 5, 6 are bent toward each other, one of which carries one of the two actuators 20 for the damping unit 19.

[0068] The intermediate guide rail 3 accommodated in the body guide rail 2 has two side walls 14, 14', which are constructed as the same piece. The intermediate guide rail 3 has rollers 12, wherein Figure 1 One of the spacers 13 can be seen, which separates the two side walls 14, 14' from each other.

[0069] The extension rail 4 is accommodated in an overlapping manner in the center rail 3. The extension rail 4 has a base plate 17 with lateral webs 18 pointing away from one another. These webs are connected to the free side legs 15, 16 of the extension rail 4, which protrude essentially perpendicularly from the base plate 17, in the direction of the center rail 3. A connecting device 30 for a sliding door is arranged and fastened to the base plate 17. The webs 18 form the tracks 10, 11 for the rollers 12 of the center rail 2.

[0070] In this arrangement of three guide rails 2 , 3 , 4 , the load of the extension guide 1 in the installed position by the sliding door is always located in the center of the guide rail, and advantageously no transverse forces occur, which would otherwise be expected in the case of a laterally arranged guide for the sliding door.

[0071] Figure 2a shows a front view of a pull-out guide 1 according to the invention, Figure 2b Shown is a rear view thereof, all in the closed position. The overlapping arrangement of the three guide rails 2, 3 and 4 can be clearly seen.

[0072] The body rail 2 has its free side legs 5, 6 with tracks 10, 11 for the rollers 12 of the intermediate rail 3, which are mounted on the side of the corresponding side walls 14, 14' facing the body rail 2. Due to the free ends 8, 9 that are bent toward each other, these rollers 12 are accommodated therein and thus guided safely. In this case, the free ends 8, 9 are not bent toward each other over the entire length of the body rail, so that the intermediate rail 3 can be introduced into or removed from the body rail 2. Figure 1 For example as shown.

[0073] The rollers 12 of the side walls 14 or 14', which are arranged on the side facing the respective other side wall, run on rails 10, 11 formed by webs 18. The rollers 12 arranged above the webs 18 are those which, in the open position of this embodiment of the extension device according to the invention, act on that part of the extension rail 4 which, in the open position, still lies within the center rail 3 and thus provides rear support.

[0074] exist Figure 2b Also visible in the drawing is a guide roller 23 around which a surrounding rope 24 runs and which has a groove as a rope guide for guiding the rope laterally.

[0075] According to the invention, a damping unit 19 acting in two directions is shown arranged on the center rail 3 .

[0076] Figure 3 The middle rail is shown in a side view, cut away in the closed position at the level of the surrounding rope 24. In this embodiment, the synchronization mechanism 21 of the invention is formed by the surrounding rope 24, two guide rollers 22, 23 and two connecting elements 25 to the body rail 2 and the extension rail 4.

[0077] The cord 24 is made of plastic or metal and has a substantially round, in particular circular, cross section, or can also be designed as a belt with a substantially rounded rectangular cross section.

[0078] At least one of the guide rollers 22, 23 has a lateral cable guide 27, in particular via a groove in the center of the roller, preferably both guide rollers each have a cable guide 27. This cable guide is shown in FIG.

[0079] In a surprisingly simple constructional manner and with great advantages, one or two guide rollers 22, 23 surrounding the cable 24 are formed or arranged on a sleeve 26 which is placed onto the spacer 13. The spacer required for the center rail 3 thus advantageously has another function, namely as a support for the guide rollers.

[0080] The two connecting elements 25 shown are detachably fastened between the guide rollers 22 and 23, one to the body rail 2 and the other to the extension rail 4, in particular snapping into corresponding openings in the rails. The connection of the cable 24 to the body rail 2 is preferably arranged above or in the region of a stop provided on the rail for maximum extension of the intermediate rail, which further simplifies the design.

[0081] It is particularly advantageous if the two spacers and the two sleeves 26 with the guide rollers 22 , 23 and any cable guide 27 are designed as identical parts.

[0082] This results in a simple assembly, as described below, while requiring only small tolerances, since only two parts engage with one another, and the closed rope loop can be mounted simply and quickly.

[0083] Figure 4 The extension guide 1 is shown in a side view from the outside, the upper side showing the open position and the lower side showing the closed position in which the three guide rails 2 , 3 , 4 overlap one another.

[0084] The single damping unit 19 of the extension guide 1 is mounted on the central rail 3. This positioning is particularly advantageous because it allows the forces acting on the extension guide 4 to be effectively absorbed during both the extension and retraction movements. The damper located in the damping unit 19, in particular the damping spring 35, is activated both from its piston side and from its housing side by the swing lock 28, which in turn advantageously enables a floating mounting of the damper.

[0085] The damping unit is contacted by the actuator 20 both in the extension direction A and in the retraction direction B and is thus actuated.

[0086] Figure 5 The three guide rails 2, 3 and 4 of the pull-out guide are shown in a perspective, individual view. On the left, the essentially C-shaped body rail 2 is shown with a base plate 7 and free side legs 5, 6 arranged thereon. In one region of the length of the body rail 2, the free ends 8, 9 are bent towards each other, thus forming an enclosed guide region for the rollers 12 of the intermediate rail 3. The stop 31 limits the pull-out path of the intermediate rail 3 in the pull-out and retraction direction. A looping rope 24 is fixed to this rail, the fixing point being located here between the guide rollers 22, 23. According to Figure 3 This fixing is carried out by means of a snap-in connection piece 25 .

[0087] The two side parts 14, 14' of the intermediate rail 3, which are spaced apart from each other by the spacer 13, carry the roller 12, the only damping unit 19 of the device 1 (together with the two damping springs 35) and the Figure 5 These synchronization mechanisms advantageously utilize the spacer 13 as a carrier for the sleeve 26, which in turn carries a guide roller 22, 23, which surrounds the rope 24 (see Figure 3 ) circulates around these guide rollers, thereby preventing slippage between the intermediate guide rail 3 and the extension guide rail 4 when pushing in.

[0088] This embodiment has one differential roller 12 ′ for each side part 14 , 14 ′, so that this exemplary embodiment relates to a differential extension guide.

[0089] The extension rail 4 shown on the right provides a track for rollers 12 on its top and bottom surfaces with two connecting plates 18, which are in turn arranged on a side part 14, 14'. The extension rail 4, which is designed as a stamped and bent part, is connected to the sliding door via connecting devices 30. These connecting devices are adapted to the respective requirements and embodiments of the pull-out furniture part in their respective embodiments and therefore vary. The cord 24 is looped around the connecting piece 25 (see the connection piece 30) which is simply snapped into the through hole of the base plate 17 of the extension rail 4. Figure 3 ) is fixed on this guide rail. The fixing point is located between the guide rollers 22, 23.

[0090] Figure 6 A detailed view of the body rail 2 in the fixing area of ​​the rope 24 is shown as a second embodiment of the synchronization mechanism according to the present invention. Figure 3 Supplement to the illustrated embodiment.

[0091] A stop 32 for the center rail 3 is shown on the base plate 7. This stop has a V-shaped cutout facing the base plate 7, terminating in a groove 33 through which the rope 24 passes. The rope 24, in turn, has a connector 25, which is used to transmit force to the main rail 2 and is therefore shaped accordingly. A hook 34 formed from the base plate 7 prevents the rope 24 from moving upward and potentially coming out of the groove 33, which would disable the synchronization mechanism. The connector 25 is connected to the rope 24, which has a circular cross-section. This embodiment significantly enhances the stop's function by providing a tensile-resistant connection between the rope 24 and the main rail 2 via the connector 25. The present invention significantly enhances the advantages of providing a pull-out guide device that is both slip-resistant and synchronized, using only a single damping device for damping in both the extension and retraction directions. This pull-out guide device can easily handle the forces generated by the sliding door in its installed position, as well as the high loads described.

[0092] This structure can also be located similarly on the drawer profile, to which the cable 24 is also fastened, as described above. However, the fastening on the extension rail can easily be designed differently from the fastening on the body rail, for example by using a connecting element 25 that can be fastened in a groove in the extension rail and is in particular fixedly connected to the cable 24.
