Definitions

  • the present invention relates to a telescopic pull-out with a stationary inner rail and at least one outer rail mounted displaceably relative to the stationary inner rail between an insertion end position and an extension end position in an insertion direction and in the opposite extension direction.
  • the outer rail comprises a front quick-fastening element and a rear quick-fastening element, which are fixed at a distance from one another on the inner rail of the telescopic pull-out.
  • the quick-fastening elements are designed for detachable mounting of the telescopic pull-out to a side rail, e.g., a side rail for an oven muffle.
  • the invention further comprises the combination of a telescopic extension with a front quick-fastening element and a rear quick-fastening element and a side grille.
  • such side grids comprise at least two vertically and substantially parallel grid bars when assembled, as well as several horizontal grid bars arranged at different heights within the muffle, which are attached to and connect the vertical grid bars.
  • the horizontal grid bars extend, at least in the front area of the side grids facing the muffle opening, usually at a distance in front of the plane formed by the vertical grid bars.
  • the horizontal grid bars For connection to and attachment to at least the front vertical grid bars, the horizontal grid bars have an angled end section at the front end.
  • the horizontal grid bars can also have an angled end section for connection to and attachment to the rear vertical grid bars.
  • the horizontal grid bars can also be connected directly to the rear vertical grid bars at the rear end without an angled end section.
  • the rear vertical bars of the oppositely mounted side rails are usually arranged at a slightly smaller distance from each other than the front vertical bars in order to ensure that the sections of the horizontal bars extending from the front to the rear vertical bars are essentially parallel and thus provide sufficient support for food carriers from the front to the rear area of the side rails.
  • such side grilles often have another horizontal grille bar at a short distance above a horizontal grille bar as described above, which is sufficiently wide to insert the food carrier between the two horizontal grille bars, but which is also sufficiently narrow that the food carrier can be supported on the upper horizontal grille bar with a rear section of the side edge to prevent it from tipping over.
  • Modern and high-quality ovens are also equipped with telescopic pull-outs for holding and moving the cooking belt carriers.
  • telescopic pull-outs for holding and moving the cooking belt carriers.
  • Another advantage of using telescopic pull-outs is that, with a sufficient number of movable rail elements, they allow the cooking belt carrier to be pulled far or even completely out of the oven chamber without tipping over.
  • Such telescopic pull-outs are usually attached to existing side racks in the oven chamber.
  • a stable, yet easily removable and re-installable attachment is practical and desirable, allowing the telescopic pull-outs to be easily removed and reinserted for cleaning or changing the position height within the chamber, or for cleaning the oven itself, for example, by pyrolysis.
  • Fasteners for quick and easy, preferably tool-free, assembly and disassembly of a telescopic extension on a side rail often have the disadvantage that the telescopic extension can become accidentally detached from the side rail and fall down under certain load situations or other circumstances.
  • Fasteners designed to prevent this often have the disadvantage of including safety devices that make assembly and disassembly of the telescopic extension complex and sometimes even require special tools.
  • the EP 2 592 968 describes a connecting device for the releasable attachment of a telescopic pull-out to a side rack of a baking oven, comprising two brackets fixed at a distance from one another on a stationary rail element of the telescopic pull-out.
  • the first bracket is designed to attach the telescopic pull-out in the front area of the side rack facing the muffle opening and comprises a spring element by means of which the bracket can be locked to the side rack.
  • the second bracket is designed to attach the telescopic pull-out in the rear area of a side rack facing the muffle rear wall, in which the horizontal rack bar does not have an angled rear end section at its rear end, but is directly connected to the rear vertical rack bar in a straight line or welded laterally.
  • the telescopic pull-out is to be releasably attached to a side rack in which the horizontal rack bar is designed differently at its rear end and has an angled rear end section, a correspondingly differently designed second bracket must be used.
  • a simple replacement is impossible or at least very complex, as the brackets are welded or glued to the telescopic rail. Therefore, different telescopic rails would have to be manufactured for both types of side rails.
  • the telescopic extension according to the invention has a stationary inner rail and at least one outer rail which is displaceably mounted relative to the stationary inner rail between an insertion end position and an extension end position in an insertion direction and in the opposite extension direction.
  • the telescopic extension is a partial extension, comprising only the stationary inner rail and the outer rail mounted thereon for linear movement as rail elements.
  • the telescopic extension is a full extension with at least three rail elements, namely the inner rail, the outer rail, and one or more intermediate rails arranged therebetween, wherein a first intermediate rail is mounted for linear movement on the stationary inner rail and the outer rail is mounted for linear movement on the first intermediate rail or, if more than one intermediate rail is provided, on the outermost intermediate rail.
  • the rail elements are slidably mounted on one another by means of rolling elements, preferably balls or rollers.
  • at least the inner rail and the outer rail have a C-shaped profile in cross-section, with a rail back formed by the web of the C-profile and with rolling element running surfaces formed on the flanges of the C-profile.
  • the telescopic extension according to the invention has a front quick-fastening element and a rear quick-fastening element, which are fixed at a distance from one another on the inner rail of the telescopic extension and are designed for a detachable mounting of the telescopic extension on a side rail.
  • front quick-fastening element and “rear quick-fastening element” are used to linguistically distinguish between the two quick-fastening elements, namely a first and a second quick-fastening element.
  • the "front quick-fastening element” refers to the quick-fastening element that is positioned further along the inner rail in the extension direction of the telescopic extension than the rear quick-fastening element. When the telescopic extension is assembled, the front quick-fastening element is positioned closer to the opening of the furnace muffle, while the rear quick-fastening element is positioned closer to the rear wall of the furnace muffle.
  • two telescopic pull-outs can be connected to opposing side rails in the oven cavity.
  • the side rail as such is not a component of the telescopic pull-out with quick-fastening elements claimed according to the invention.
  • the description of essential structural features of a side rail, also in independent claim 1, serves to define features of the quick-fastening elements, since these are suitable and designed according to the invention for detachable mounting of the telescopic pull-out to such a side rail.
  • Such a side grille has at least one front vertical grille bar, a rear vertical grille bar spaced from the front vertical grille bar and arranged substantially parallel thereto, and at least one horizontal grille bar extending substantially perpendicular to the vertical grille bars and connecting them.
  • the horizontal lattice bar has at a front end an angled front end section which is connected to the front vertical lattice bar, extends out of the plane spanned by the two vertical lattice bars and, at an angle, merges into a horizontal section of the horizontal lattice bar which extends to the rear vertical lattice bar.
  • the horizontal lattice bar has, at a rear end opposite the front end, either i) an angled rear end section which is the same or similar to the front end and which is connected to the rear vertical lattice bar extends out of the plane defined by the two vertical lattice bars and merges at an angle into the horizontal section of the horizontal lattice bar, or ii) it is directly connected to the rear vertical lattice bar, ie without an angled end section.
  • the rear quick-fastening element of the telescopic extension according to the invention is suitable for attachment to both types of side rails with or without an angled end section of the horizontal rail, without the need to change the rear quick-fastening element or even to produce different telescopic extensions with different rear quick-fastening elements.
  • the side grille can have several horizontal grille bars of the type described herein at different heights one above the other and usually also has them for mounting one or more telescopic extensions at different heights within the furnace muffle.
  • a rear quick-fastening element designed in this way has the advantage that it is suitable for detachable mounting of the telescopic extension on various commercially available side rails, namely those in which the horizontal rail at its rear end either i) has an angled rear end section in the same way or similarly to the front end, which is connected to the rear vertical rail and extends out of the plane spanned by the two vertical rails and angled into the horizontal section of the horizontal grid bar, and those in which the horizontal grid bar is connected at its rear end ii) directly to the rear vertical grid bar, i.e. without an angled end section.
  • the rear quick-fastening element according to the invention is also suitable for a further variant of side grids in which two rear vertical grid bars are arranged in the rear region as described herein and the horizontal grid bar has at its rear end an angled rear end section which is connected to a first of the two rear vertical grid bars in the manner described in i), and in which the horizontal section of the horizontal grid bar in front of the angled section is connected to the second of the two rear vertical grid bars, for example by laterally abutting it and being welded to it.
  • side grids of variants i) and ii) in which the horizontal grid bar is connected to only one rear vertical grid bar.
  • the vertical grating bar is generally arranged closer to the side wall than in side gratings in which the horizontal grating bar is directly connected to the rear vertical grating bar in a linear connection or directly welded laterally, in order to ensure that the horizontal section of the horizontal grating bar runs straight from front to rear, i.e., essentially parallel to the horizontal section of the horizontal grating bar of the second side grating arranged on the opposite muffle wall.
  • the rear quick-fastening element of the aforementioned type according to the invention is thus suitable for secure attachment to both types of side gratings with different positioning of the vertical grating bars and would also be suitable for side gratings with two rear vertical grating bars in the two described positions.
  • This rear quick-fastening element according to the invention costs can be saved and flexibility in use can be achieved, since it is not necessary to equip telescopic extensions according to the invention with different rear quick-fastening elements for the two different types of side rails, both of which are or can be commercially available.
  • the support angle has a cutout or both the support angle and the second contact section have a cutout which is designed and arranged for inserting a horizontal grid bar of a side grid when the telescopic rail is mounted on the side grid.
  • Such a cutout is advantageous or even necessary for securing the rear quick-fastening element to a side grating in which the horizontal grating bar is connected directly to the rear vertical grating bar at its rear end, i.e. without an angled end section.
  • the first contact section comes into contact with the vertical grating bar, while the second contact section is arranged closer towards the muffle side wall and must therefore be guided past the horizontal grating bar for installation of the rear quick-fastening element.
  • the free space required for this at the support angle is provided by the cutout.
  • the horizontal grating bar When installed, the horizontal grating bar extends through the cutout and the support angle rests on the section of the horizontal grating bar extending through the cutout.
  • the support bracket has a fixing portion for connecting the rear quick-fastening element to the stationary inner rail.
  • the fixing portion of the rear quick-fastening element is preferably a flat portion on the rear quick-fastening element aligned parallel to the rail back of the inner rail, which preferably extends from the support bracket and rests against the rail back of the inner rail and is welded or glued thereto.
  • the first contact section and/or the second contact section has a U-shaped cross-section for engaging around a rear vertical grid bar from a side facing in the extension direction (A) as well as from the two sides perpendicular thereto.
  • the contact section with a U-shaped cross-section is pushed over the vertical grid bar in the insertion direction until it rests against it in the insertion direction and engages it with the U-legs, thus preventing further movement both in the insertion direction and transversely thereto.
  • the first contact section and/or the second contact section has an L-shaped cross-section for encompassing a rear vertical grid bar from a side facing in the extension direction (A) as well as from a side perpendicular thereto.
  • the contact section with the L-shaped cross-section is pushed in the insertion direction against the vertical grid bar until the foot of the L-shaped profile rests against it in the insertion direction and the further L-leg is laterally of the Vertical lattice bar is arranged so that further movement in the insertion direction as well as transversely thereto in the direction of the other L-leg is prevented.
  • An L-shaped profile of the contact section may be sufficient for secure fastening of the rear quick-fastening element, especially if movement in the other transverse direction, which is not prevented by the profile of the L-leg, is blocked by another component in the assembled state.
  • the support bracket of the rear quick-fastening element expediently has a support surface for placing and supporting the rear quick-fastening element on a horizontal lattice bar.
  • this support surface can be a horizontally straight lower edge of the support bracket.
  • the support bracket has a vertically downwardly open recess with a support surface for supporting the rear quick-fastening element on a horizontal lattice bar and with lateral edges extending from the support surface for gripping the horizontal lattice bar.
  • the support bracket with the recess is guided over the horizontal lattice bar and then lowered until the upper inner edge of the recess rests on the horizontal lattice bar.
  • the lateral edges of the recess can then block lateral movement in the assembled state.
  • This embodiment is suitable, for example, in combination with a first contact section with an L-shaped cross-section, as described above.
  • a quick-fastening element suitable for releasably securing the telescopic extension in the front section of the side rail can generally be used.
  • different quick-fastening elements may be suitable.
  • the front quick-fastening element is expediently designed such that, like the rear quick-fastening element according to the invention, it securely engages with the side rail upon movement of the telescopic extension in the insertion direction during assembly in the front area of the side rail.
  • the front quick-fastening element comprises a holder and an anti-lift device.
  • the holder and the anti-lift device are formed as separate components.
  • the holder and the anti-lift device are permanently connected to one another or connectable, or they are formed as a single piece.
  • the holder of this preferred front quick-attachment element has a hook with a receiving area and a hook mouth, wherein an angled front end section at the front end of the horizontal section of the horizontal grid bar of a side grid can be inserted into the receiving area of the hook through the hook mouth.
  • the hook mouth is expediently accessible from the insertion direction for inserting the angled front end section on the horizontal grid bar when mounting the telescopic extension on a side grid by sliding the hook over the angled front end section in the insertion direction.
  • the holder of this preferred front quick-fastening element has a holding section designed for engagement with the front vertical grid bar or for encompassing the front vertical grid bar of a side grid, which holding section has at least one contact surface facing in the insertion direction (E) for engagement with a surface of the front vertical grid bar of a side grid facing in the extension direction (A).
  • the holding section is brought into contact with or engagement with the front vertical grid bar when the hook is pushed over the angled front end section of the horizontal grid bar in the insertion direction. If the holding section is designed for encompassing the vertical grid bar, it prevents a lateral movement of the holder away from the side grid in the direction of the muffle interior when the telescopic extension is mounted.
  • the holder of this preferred front quick-attachment element further comprises a fastening portion for connecting the holder to the stationary inner rail.
  • the fastening portion is a flat portion of the holder aligned parallel to the rail back of the inner rail, which portion rests against the rail back of the inner rail and is welded or glued thereto.
  • the anti-lift device of this preferred front quick-attachment element has a support section, a hook-and-jaw locking section and a spring section.
  • the support portion of the anti-lift device is fixedly or detachably connected to the stationary inner rail. Similar to the attachment portion of the holder, the support portion of the anti-lift device is preferably a flat portion of the anti-lift device aligned parallel to the rail back of the inner rail, which portion rests against the rail back of the inner rail and is welded or glued thereto. In an alternative embodiment, the Support section of the anti-lift device is firmly connected to the holder or formed integrally with the holder.
  • the hook jaw securing section of the anti-lifting device is connected to the support section via the spring section and can be moved from a securing position in the extension direction (A) into a release position against a restoring force of the spring section, so that the hook jaw with the hook jaw securing section has a first opening width in the release position and with the hook jaw securing section in the securing position has a second opening width determined by the hook jaw securing section, which is smaller than the first opening width.
  • the telescopic extension according to the invention allows quick and easy assembly and disassembly on a side rail and nevertheless effectively prevents unintentional loosening or lifting of the telescopic extension from the side rail.
  • the hook jaw locking section can be moved from the locking position to a release position by actuating it against the spring force of the spring section in order to increase the opening width of the hook jaw so that the hook can be lifted from the angled front end section of the horizontal grid bar.
  • actuating the hook jaw locking section against the spring force of the spring section is ergonomic and simple.
  • the spring section is accessible from the front of the telescopic extension or the side grid. The movement of the hook jaw locking section occurs in the extension direction and not in a sideways movement perpendicular to the extension direction, which is why no additional space needs to be kept free for moving the hook jaw locking section. This also allows for the installation of an ergonomic and easily accessible operating lever.
  • the solution according to the invention also allows the provision of an additional cover to shield the telescopic extension towards the interior of the oven muffle, in order to protect the telescopic extension from dirt, without impairing the accessibility and operability of the front holder.
  • the present invention allows for a simpler spring geometry than, for example, the EP 2 592 968 known front fastener.
  • the hook locking section serves to limit the lifting of the telescopic extension and prevent the hook from being lifted out of engagement with the angled end section of the horizontal railing bar by causing the angled end section to engage the hook locking section. If a very large force is exerted when lifting the telescopic extension, there is a risk that the stability of the spring section and/or the attached hook locking section will be insufficient to prevent the hook from being lifted out, e.g., if the acting forces are large enough to inadvertently bend the spring section and/or the hook locking section.
  • the bending protection device advantageously limits or prevents such undesired bending by being designed such that it extends from the hook jaw locking section and/or the spring section and rests with a free end against a contact surface of the inner rail, the holder or the anti-lifting device itself or is arranged at a distance therefrom, wherein the contact surface of the inner rail, the holder or the anti-lifting device forms a stop for limiting the movement of the hook jaw locking section in a direction away from the hook of the holder and perpendicular to the extension direction (A) of the telescopic extension.
  • the contact surface is a vertically upward-facing surface of the inner rail or the fastening section of the holder or the support section of the anti-lifting device.
  • the bending protection device extends from the hook jaw locking section vertically or at an acute angle of preferably 1° to 20° to the vertical downwards.
  • the opening of the hook jaw on the front holder is preferably oriented in the insertion direction (E) for insertion of an angled front end portion at the front end of the horizontal portion of the side rail into the receiving area of the hook.
  • the hook jaw securing portion expediently extends from the spring portion in the insertion direction (E). In the extension direction (A), the hook jaw securing portion is secured to the spring portion.
  • the spring section is designed as a resilient plate or a resilient tab formed, the plane or surface of which is arranged perpendicular to the extension direction (A) and preferably parallel to the front vertical lattice bar.
  • the spring section is arranged such that it is in a non-preloaded rest position when the hook locking section is in a securing position, and it is resiliently preloaded with a restoring force in the extension direction (A) when the hook locking section is in a release position.
  • the spring section can also have a preload in the insertion direction (E) in the securing position if its restoring movement is limited by a stop before reaching a non-preloaded rest position in the insertion direction (E), e.g., by contact with the holding section of the holder, which rests against or engages around the front vertical lattice bar, or via the previously described bending protection.
  • an actuating tab extending in the extension direction or at an acute angle to the extension direction is provided on the spring section, on the hook-type locking section, or on a bending lock extending from the hook-type locking section or the spring section to the inner rail.
  • the actuating tab can be actuated by an operator to move the hook-type locking section from a securing position to a releasing position.
  • the actuating tab is preferably formed as a section extending from the upper end of the spring section in the extension direction obliquely upwards, preferably at an angle of approximately 40° to 70° to the vertical, integrally with and extending from the spring section.
  • the actuating tab allows simple and ergonomic actuation to move the hook-type locking section from a securing position to a releasing position against the spring force of the spring section in the extension direction.
  • a surface of the fastening section of the holder expediently extends substantially parallel and perpendicular to the extension direction (A).
  • the surface of the fastening section also extends parallel to the back of the inner rail and is secured thereto, preferably by welding or gluing.
