Description

Technical Field

[0001] The present invention relates to a guiding device having a side grid frame and a pull-out guide, wherein the side grid frame has at least two spaced-apart vertical supports and at least one horizontal bar, the horizontal bar connecting the two supports by an anti-tilt device, wherein the anti-tilt device is fixed to the horizontal bar by an end section and, viewed longitudinally along the bar, has a C-shaped section, a guide section extending above the bar and substantially parallel to the bar, and the pull-out guide includes at least two rails movable relative to each other, and the fixed rails are held on the side grid frame by a front retainer and a rear retainer. Background Technology

[0002] DE102006015444B4 discloses a telescopic pull-out device for attachment to a side rack, having two vertical supports and a pair of horizontally extending guide rods connected to the vertical supports on both sides. The lower guide rod serves as a support, and the upper guide rod serves as an anti-tilt device to prevent the food tray from lifting in its partially extended position. The telescopic pull-out device, having a fixed track and a movable running track, is fixed to the pair of guide rods, wherein the running track has a web disposed between the two guide rods of the pair. This allows the upper guide rod to form an anti-tilt device when the food tray is placed on the running track. Due to the pair of guide rods, the guide device formed in this way requires a large amount of metal, which slows down the heating of the oven and requires energy. Furthermore, the anti-tilt device prevents the food tray from lifting when it is already mostly in front of the oven. Summary of the Invention

[0003] Therefore, the object of the present invention is to provide a guide device having an improved structure in which the pull-out guide can be easily fixed to the side frame.

[0004] The guiding device according to the invention includes a side frame and a pull-out guide, wherein the side frame has at least two spaced-apart vertical supports and at least one horizontal bar, the horizontal bar connecting the two supports by an anti-tilt device, wherein the anti-tilt device is fixed to the horizontal bar by an end section and, viewed along the longitudinal direction of the bar, has a C-shaped section, the guide section extending above the C-shaped section and extending substantially parallel to the bar. The guide section forms the anti-tilt device, which prevents a food tray, such as a baking tray, from tilting on the horizontal bar in a partially extended position. The pull-out guide includes at least two tracks movable relative to each other, wherein a fixed track is held on the side frame by a front retainer and a rear retainer, and the rear retainer engages by a web below the lower and / or upper legs of the C-shaped section of the anti-tilt device to secure the pull-out guide in the installed position and prevent the pull-out guide from lifting and twisting about the longitudinal axis in the rear region. This allows for a compact design of the guide device, as the anti-tilt device with the guide section is shorter above the horizontal bar than the horizontal bar itself, for example, at least 15%, preferably at least 20%, shorter than the horizontal bar between the two vertical supports in the longitudinal direction of the horizontal bar. This also allows the pull-out guide or retaining rail to be manufactured accordingly in a shorter manner, since the rear retainer is no longer mounted on the rear vertical support, but rather on a C-shaped section spaced apart from the vertical support. This means that the guide device can be manufactured using less material, particularly less metal, and its compact design makes it possible to guide food trays or other components supported by the guide device.

[0005] Preferably, the pull-out guide, suspended by a front retainer and a rear retainer, is secured to the side grid frame. This allows the pull-out guide to be detachably held to the side grid frame and can be easily assembled by mounting the rear retainer to the C-section of the anti-tilt device and the front retainer to the front vertical support. The pull-out guide is then held in the desired position by gravity and the retainers.

[0006] In a preferred embodiment, the rear retainer is slidable onto the C-shaped section of the anti-tilt device for installation. This allows for installation by means of sliding motion, particularly without tools. The rear retainer can U-clamp the horizontal bar for fixation perpendicular to the longitudinal direction of the bar. Alternatively or additionally, the rear retainer can U-clamp the lower leg of the C-shaped section, thus securing the rear retainer to prevent it from being raised or lowered. The rear retainer may also have a stop surface that rests against the C-shaped section, for example, in the vertical connection between the two horizontal legs. For example, in the assembled position, the web of the rear retainer can engage the connecting section at the rear, preventing the pull-out guide from being pulled out in the horizontal direction perpendicular to the longitudinal direction of the bar. Preferably, the rear retainer prevents movement of the pull-out guide in five spatial directions, and the pull-out guide, together with the retainer, can be removed substantially only in the longitudinal direction of the pull-out guide.

[0007] To stably secure the pull-out guide, the rear retainer can engage the fixing rail from below via sections. Optionally, the front retainer can also engage the fixing rail from below via sections. For this purpose, the retainer can be designed at an angle, such that the fixing rail is positioned on two horizontal sections of the retainer. Alternatively, the front and / or rear retainers can also be attached to the side surfaces of the fixing rail.

[0008] Preferably, the front retainer hooks onto the end section of the horizontal bar, particularly onto an angled end section, and for this purpose may have a slot-shaped receiving portion through which the end section passes. Furthermore, the front vertical strut may be surrounded by a U-shaped section on the front retainer.

[0009] Preferably, an upwardly projecting web is fixed to or integrally formed on the movable track, the web being arranged laterally adjacent to the horizontal bar and projecting upward to form a support surface for the food tray. A cover can be fixed to the movable track, forming the support surface and covering the gap between the fixed track and the movable track. This improves hygiene by preventing contaminants from accumulating between the tracks. Thus, the cover can cover the essentially horizontal slot between the movable track and the fixed track. The cover can be fixed to the movable track, for example, by welding. Alternatively, the cover can also be attached to the movable track by locking and / or riveting. In the case of locking, the cover can also be detachably attached to the movable track. The locking device can also optionally be integrally formed with the cover and the movable track. The support surface for receiving the food tray is preferably arranged above the top of the horizontal bar and below the guide section of the anti-tilt device. This allows the food tray to be placed on the horizontal bar and secured by the anti-tilt device to prevent lifting. Alternatively, the guide device is mounted on the side rack, and the food tray rests on the support surface, and is also secured by the guide section of the anti-tilt device to prevent lifting.

[0010] The pull-out guide is preferably disposed in a plane below the horizontal bar. The pull-out guide can be arranged such that all its tracks are below the plane of the horizontal bar, such that all tracks of the pull-out guide are arranged in a space between the horizontal bar and an anti-tilt device disposed below it for lowering the horizontal bar. The mounting space between the horizontal bar and the anti-tilt device disposed below it can therefore be used to position the pull-out guide.

[0011] In addition to fixed and movable tracks, pull-out guides may also have an intermediate track for pull-out extension, whereby the tracks of the pull-out guides are preferably movable relative to each other by means of rolling elements.

[0012] The rear retainer and / or the front retainer are preferably made of bent metal sheets. When the bent metal sheet is in a flat state as a blank, its area can be less than 20 cm². 2 This is to keep the amount of material used in the retainer low.

[0013] The guiding device according to the invention is preferably used in household appliances, particularly cooking appliances, whereby the guiding device according to the invention can be installed on the opposite side of the cooking chamber. Attached Figure Description

Detailed Implementation

[0015] The guiding device 1 includes a side frame 2 having at least two vertical supports 3 spaced apart from each other, with a plurality of horizontally extending rods 4 arranged between the vertical supports. In this embodiment, the horizontal rods 4 have angled end sections 5 on at least one side, which are fixed to the front vertical support 3 in the installation position. In the rear region, the vertical supports 3 are fixed to the straight sections of the horizontal rods 4, where optionally angled end sections 5 may also be provided, to which the supports 3 are fixed.

[0016] The side shelf 2 includes an anti-tipping device fixed to a horizontal bar 4. The anti-tipping device is shorter than the horizontal bar 4 in the longitudinal direction, preferably between 10% and 80%, particularly 20% to 60% shorter. Each anti-tipping device includes a C-shaped section viewed along the longitudinal direction of the horizontal bar 4, wherein a lower support leg 7 is connected to the horizontal bar 4, and a connecting section 8 is formed between the lower horizontal support leg 7 and the upper horizontal support leg 9. The upper horizontal support leg 9 is connected to a guide section 6 that is substantially parallel to and extends above the horizontal bar 4. In the illustrated embodiment, the guide section 6 is connected to the horizontal bar 4 via the C-shaped section on opposite sides, but it may also optionally be fixed at one end to a vertical support 3. Because the anti-tipping device is spaced apart from the vertical support 3 at least in the front region, the food tray can be raised on the bar 4 before it moves horizontally away from the horizontal bar 4. In the illustrated embodiment, four horizontal bars 4 are shown on the side shelf 2, each with an anti-tipping device. However, the number of horizontal bars 4 with anti-tilt devices can be adapted to the installation situation in household appliances.

[0017] Pull-out guides 10 are fixed to at least one horizontal bar 4, each pull-out guide 10 having a fixed rail 11 and a movable rail 13. In the illustrated embodiment, an intermediate pull-out extension rail 12 is arranged between the fixed rail 11 and the movable rail 13. A strip cover 14 is fixed, for example welded, to the movable rail 13, covering the slot between the fixed rail 11 and the movable rail 13. The cover is located inside the side rack 2 relative to its installation in the oven. The cover 14 has a tab 15 on its front side, which optionally restricts the retracted position and can move upward to the front vertical support 3. In the rear region, an upwardly projecting web 16 is formed on the cover 14, which restricts the sliding of the food tray on the cover 14. The cover 14 has a support surface 17 at the top, on which the food tray, such as a baking tray, can be placed edge to. The support surface 17 is located above the horizontal bar 4 and below the guide section 6 of the anti-tilt device.

[0018] The fixed track 11 is secured by a front retainer 20, preferably hooked to an angled end section 5 of the horizontal bar 4, wherein at least one U-shaped section additionally surrounds the vertical support 3. The front retainer 20 includes a U-shaped bracket 21 arranged around the front support 3. Furthermore, a vertical web 22 is provided through which the fixed track 11 is suspended. The front retainer 20 can be secured to the side frame 2 by clamping or locking into place. Additionally, the front retainer 20 can be secured in the mounting position by a spring element.

[0019] The pull-out guide 10 is also secured to the fixed rail 11 by a rear retainer 30, which holds the horizontal bar 4 and the C-shaped section of the anti-tilt device.

[0020] exist Figures 2A to 2C The rear retainer 30 in its assembled position is shown in detail. The rear retainer 30 includes a U-shaped section 31 arranged around the horizontal bar 4. A web-shaped tab 32 is also integrally formed on the retainer 30, which engages the connecting section 8 of the C-shaped section at the rear, i.e., arranged outwards relative to the mounting position, thereby preventing movement in five spatial directions by means of the rear retainer 30. The rear retainer 30 also has a vertical web 34 with an angled section 35 at its end, which engages below a fixed track 11 and is fixed to the track, for example, by welding.

[0021] like Figure 2C As shown, the pull-out guide with tracks 11, 12, and 13 is located entirely below the plane defined by the horizontal bar 4 and the angled end section 5. Tracks 11, 12, and 13 can move relative to each other via rolling elements. Furthermore, viewed in the longitudinal direction of the horizontal bar 4, the pull-out guide 10 is located between the two vertical supports 3, but optionally may extend beyond the vertical supports 3 on one or both sides.

[0022] Figure 3A and Figure 3B The rear retainer 30 is shown, preferably made of bent metal sheet. The retainer 30 includes a U-shaped section 31 for surrounding the horizontal bar 4, the U-shaped section having a lower leg and an upper leg, wherein a tab 32 is integrally formed with the upper leg, the tab projecting vertically upward and engaging the connecting section 8 from the rear on the outside. Furthermore, a web 33 is integrally formed on the retainer 30, which engages the lower leg 7 of the C-shaped section below, thereby preventing the rear retainer 30 from being lifted in the installed position. Additionally, an angled section 35 for securing the track 11 is visible.

[0023] Figures 4A to 4CThe assembly of the rear retainer 30 is shown in detail. First, the rear retainer 30 is secured to the pull-out guide 10, specifically welded to the fixed rail 11. Then, the unit consisting of the rear retainer 30 and the pull-out guide 10 is positioned on the side frame 2, wherein the rear retainer 30 is placed around a horizontal bar 4 having a U-shaped section 31, as shown. Figure 4B As shown. In this pre-assembled position, the rear retainer 30 can be pushed backward along the longitudinal direction of the horizontal bar 4 until the tab 32 engages with the connecting section 8 of the C-shaped section of the anti-tilt device at the rear, as shown. Figure 4C As shown. In the installed position, the rear retainer 30 thus prevents movement of the fixed track 11 in five spatial directions. Optionally, the tab 32 can also be designed to engage the vertical connecting section 8 in an L-shape or U-shape.

[0024] Figure 5A and Figure 5B A second embodiment of the guide device 1' according to the invention is shown, wherein the side grid 2 is designed as in the first embodiment. The pull-out guide 10 and the front retainer 20 also have the same structure, only the rear retainer 40 for fixing the track 11 is modified.

[0025] Figures 6A to 6C The rear retainer 40 in its installed position is shown in detail. The rear retainer 40 includes a vertical web 41 having an angled section 43 at its lower end that engages with a fixing rail 11 below. Alternatively, the front retainer 20 and / or the rear retainer 40 may also be attached to the side surface of the fixing rail 11. The fixing rail 11 may be fixed to, in particular welded to, the angled section 43. A front protrusion 45, which is a web, is also formed on the vertical web 41, projecting rearward and forming a slotted receiving portion 44 together with the horizontal web 42 above the retainer 40, into which the lower leg 7 of the C-shaped section of the anti-tilt device is inserted. The lower leg 7 does not necessarily engage all the way to the end of the receiving portion 44, but is arranged in a substantially form-fitting manner between the upper web 42 and the lower protrusion 45. The retainer 40 also includes angled tabs 46 on the upper web 42, in particular two spaced tabs 46, which are supported against or placed on the horizontal bar 4. Therefore, the rear retainer 40 can block the movement of the pull-out guide 10 in four spatial directions, with the front retainer 20 blocking the movement in the rearward direction.

[0026] Figure 7A and Figure 7B The rear retainer 40 is shown in detail, and it is also made of bent metal sheet. The rear retainer 40 is basically C-shaped and includes an angled section 43, a vertical web 41, and an upper web 42. A slotted receiving portion 44 for insertion of the lower support leg 7 is formed between a protrusion 45 on the vertical web 41 and the upper web 42.

[0027] Figures 8A to 8DThe assembly of the rear retainer 40 is shown in detail. First, the rear retainer 40 is mounted on the pull-out guide 10, specifically welded to the fixed rail 11. Then, the unit consisting of the pull-out guide 10 and the rear retainer 40 can be positioned on the side frame 2, thereby, as... Figure 8B and Figure 8C As shown, the slot-shaped receiving portion 44 is arranged adjacent to the lower support leg 7 of the C-shaped section of the anti-tilt device. Then, the pull-out guide with the rear retainer 40 is pushed rearward onto the lower support leg 7 of the C-shaped section of the anti-tilt device, as... Figure 8D As shown. In this case, the horizontal web 42 contacts between the horizontal bar 4 and the connecting section 8 to secure the retainer 40 in the lateral direction.

[0028] The above embodiments can be optionally combined; for example, the retainer 40 may additionally have a U-shaped section 31 to surround the rod 4.

[0029] Figures 9A to 9C The cover 14 is shown mounted on the pull-out guide 10. An angled protrusion 19 is formed on the vertical wall portion of the cover 14, which surrounds the movable track 13 in a U-shape. Two recesses are provided on the strip-shaped, angled protrusion 19, and a locking web 23 is integrally formed from the material of the recesses. A spring-loaded locking element 24 is formed on the locking web 23. On the opposite side, another locking web 23' is provided on the angled protrusion.

[0030] The strip cover 14 is placed on the movable track 13 from above, and the locking web 23 is pressed outward until the spring-loaded locking element 24 engages the edge of the movable track 13 from behind. On the opposite side, the locking web 23' also engages with a receiving portion or recess in the movable track 13, thereby locking the cover 14 onto the movable track 13. Instead of the angled web 16, an improved web 16' is formed on the cover 14, which is formed parallel to the longitudinal direction of the pull-out guide 10.

[0031] Figure 10A and Figure 10B An additional cover 14 is shown, which is mounted on the movable track 13 of the pull-out guide 10 by an improved fastening device. Two upwardly projecting hook elements 27 are formed on the movable track 13 of the pull-out guide 10. The cover 14 includes strip-shaped, angled protrusions 19, in which two recesses 26 are formed on the horizontal web 25 of the angled protrusions 19, into which the hook elements 27 can be inserted.

[0032] Furthermore, a hook 29 is formed on the movable track 13, protruding in the opposite direction to the hook element 27. A locking web 28 is formed on the horizontal web 25 of the cover 14, which can engage with the hook 29 at its free end. The cover 14 is first placed on the movable track 13 such that the angled protrusion 19 engages with the movable track 13 and the hook element 27 protrudes through the recess 26. The cover 14 is then moved until the hook element 27 engages with the horizontal web 25 and the free end of the locking web 28 engages with the hook 29. This mechanically secures the cover 14 to the movable track 13. Instead of the angled tab 15, the cover 14 has an improved tab 15' oriented parallel to the longitudinal direction of the pull-out guide 10. Optionally, the tab 15' may also be angled and cover the plate 18 attached to the movable track 13, which restricts the movement of the movable track 13 relative to the fixed track 11.

[0033] Figure 11A and Figure 11B Another embodiment is shown for securing the cover 14 to a movable track 13 of the pull-out guide 10. An upwardly projecting hook element 27 is formed on the movable track 13, which can be inserted into a recess 26 on an angled protrusion 19 of the cover 14. An opening 36 is present on the movable track 13, and an opening 37 is present on the horizontal web 25 of the cover. After the cover 14 has been placed on the movable track 13, the cover 14 is secured by rivets 38 inserted into the openings 37 and 36.

[0034] Different fastening methods for cover 14 can be combined with different embodiments for fastening to the side grid as needed.
