Description

The present invention relates to an extractor hood device with a front flap.

It is known to attach movable front flaps to extractor devices in order, for example, to divert gases and vapors generated during cooking, or to provide easier access to filters to be changed. The front flaps are mostly attached to the appliance housings of the extractor hoods with screwed or pinned connection points. Often, bearing or hinge solutions are used, which can be complex due to the increased use of components or numerous assembly steps in assembly or in their implementation.

the end DE 10 2006 053 076 A1 an extractor hood is known which comprises a housing and a vapor shield pivotably mounted on the housing. The extractor hood is characterized in that the vapor shield is connected to the housing via at least one bearing, which is a rotary bearing. The bearing axis is defined by the at least one bearing, which is formed by a bearing device provided on the housing and / or the vapor shield and only allows the vapor shield to pivot relative to the housing.

However, the effort involved in final assembly prevents a user from being able to assemble the front flap himself. Consequently, the front of the device cannot be enclosed with the rest of the device as an individual part, which could lead to a simplification in production and packaging, as well as to a simplification of the construction of the device for the user.

Based on the known prior art, the object of the present invention is to provide an improved extractor device and corresponding methods.

The object is achieved by an extractor device with the features of claim 1. Advantageous further developments result from the subclaims, the description and the figures.

Accordingly, an extractor device is proposed, comprising a front flap and a body. The front flap has at least one rotation pin. The body comprises at least one link guide and at least one retaining pin. The retaining pin is arranged in such a way that it protrudes at least partially into the at least one link guide. The front flap is adapted so that the at least one rotation pin can be moved through the at least one link guide in order to position the front flap in an end position. The at least one rotation pin and the at least one retaining pin form at least one swivel joint when the front flap is in the end position.

The end position is a position of the front flap that the front flap assumes after its assembly for normal use of the extractor device. In this position, the at least one rotation pin and the at least one retaining pin form at least one swivel joint around which the front flap can be pivoted. The at least one swivel joint can thus form a form-fitting connection between the front flap and the body, which holds the front flap in all degrees of translational freedom relative to the body, while maintaining a, preferably horizontal, thing of rotation which ensures the opening and closing of the front flap. Here, the at least one retaining pin can hold the front flap independently and enable the pivoting movement.

A slot guide is understood to be a recess that is made on a surface of the body. The surface of the body into which the link guide is introduced is the surface which, in the assembled state of the extractor device, faces the area of the front flap in which the rotary pin is arranged. The link guide preferably runs vertically at least in some areas. In particular, the link guide preferably has an opening at an upper end from which the link guide extends downward. The extension can be inclined from the vertical. The at least one retaining pin protrudes at least partially into the at least one link guide. The retaining pin is perpendicular to the width and length of the link guide. In an advantageous embodiment, the at least one retaining pin has a length which corresponds to the depth of the link guide and is preferably longer than the depth of the link guide. Here, the retaining pin protrude beyond the open side of the link guide, that is, beyond the surface in which the link guide is introduced. The link guide serves in particular to guide the rotary pin to the retaining pin or away from it.

The at least one rotation pin can interact with the at least one retaining pin after the at least one rotation pin has been inserted into the at least one link guide of the body.

The front flap is adapted so that the at least one rotation pin can be moved through the at least one link guide. This is particularly advantageous during assembly, since the front flap can only be hung or inserted into the at least one link guide. The rotation pin can then be moved onto the retaining pin in the link guide. The at least one link guide can in each case guide the at least one rotation pin in such a way that it comes into contact with the respective at least one retaining pin and can interact with it in order to form the at least one swivel joint. The pivot joint is preferably formed by the engagement of the retaining pin in the rotation pin. The interaction of the retaining pin with the rotation pin is preferably a temporary cooperation. In particular, the connection between the retaining pin and the rotation pin is preferably a releasable connection, in particular a releasable connection that can be established and released without the use of tools.

The body or the rest of the device is understood to mean the extractor hood with the exception of the front flap. The body can have a housing or device housing, which can essentially form the outer surface of the body. The extractor hood device and in particular the body have a rear side, a front side, a left side, a right side, and an upper side and a lower side. The front flap can be arranged on the front and can be pivoted via the at least one pivot joint. The front flap can preferably have a recess in its rear edge which has a width which corresponds to the width of the body. The front flap is provided on the body in such a way that the front side of the body and part of the side walls of the body lie in the recess. The front flap is preferably arranged on the front of the body in such a way that that the axis of the swivel joint points in a lateral, horizontal direction so that the front flap can be swiveled forwards / backwards. In the case of extractor devices which are set up to be attached to a wall, the rear side of the body is usually facing the wall.

In an advantageous embodiment, the at least one link guide and the at least one rotation pin of the front flap are adapted and / or arranged in such a way that the front flap already during assembly, even before the interaction, in particular with one another, of the at least one rotation pin with the at least one retaining pin , is held by the interaction of the at least one rotation pin and the at least one link guide, in particular guiding the rotation pin in the link guide, and cannot crash and / or fall unhindered when the front flap is no longer held by the user.

Such a configuration is also advantageous if the at least one rotation pin is removed from the at least one retaining pin, for example by unintentional lifting of the front flap from its end position, since the front flap is held by the interaction of the at least one rotation pin and the at least one link guide and cannot fall and / or fall unhindered. The front flap would first have to be lifted upwards in order to move the at least one rotation pin through and finally out of the at least one link guide in order to remove the front flap from the body.

An advantage of the embodiment according to the invention over other types of fastening is a simple and safe assembly process and the possibility of dispensing with conventional hinge systems, which sometimes require tools for assembly. This also opens up the possibility of assembly of the front flap by the end user and has the further advantage that the front flap can be enclosed with the rest of the device, which can simplify packaging and transport. It is also possible, among other things, to sell the front flap separately. Another advantage that is associated with the fact that the end user uses the front flap himself can be a considerable saving in assembly and testing costs in production.

Another advantage is the easier installation of the extractor device, in particular easier installation on a wall, since the body can be attached first and then the front flap can be installed.

Another advantage of the present invention can be seen in the fact that the front flap can be dismantled again in a simple manner. For this purpose, the front flap can, for example, be lifted out of its end position and then moved in such a way that the at least one rotation pin is first moved through and then out of the at least one link guide.

The degrees of freedom of the front flap are determined or restricted by the at least one link guide and the at least one rotation pin. In the end position, the front plate can pivot about the axis of the at least one rotation pin and retaining pin. In an advantageous embodiment, the pivoting movement is additionally restricted by stops on the device side. These stops can be implemented, for example, by pins which are arranged on the device housing and in particular on the body in addition to the retaining pin and, when the front flap is in a certain position, abut against the front flap in order to block further pivoting movement.

In an advantageous embodiment, the body has a right side and a left side and comprises at least one right and one left slide guide, the right slide guide being arranged on the right side of the body and the left slide guide being arranged on the left side of the body. Furthermore, the extractor device comprises at least one right and one left retaining pin, which are each arranged so that the right retaining pin at least partially protrudes into the right link guide and the left retaining pin at least partially protrudes into the left link guide. The front flap comprises at least one right and one left rotating pin, the front flap being adapted so that the right rotating pin can be inserted into the right link guide and at the same time the left rotation pin can be inserted into the left link guide and that the right rotation pin can be inserted through the right link guide and at the same time the left rotation pin can be moved by the left link guide to the To position the front flap in an end position, wherein the right rotation pin and the right retaining pin form a right swivel joint and the left rotation pin and the left retaining pin form a left swivel joint when the front flap is in the end position. This embodiment has the advantage that the flap can be held on the body in a stable manner.

In an advantageous embodiment, the at least one retaining pin is a metal pin. This is advantageous because the retaining pin has a high degree of stability as a result. This high stability is particularly important for the reason that in the end position of the front flap the entire weight of the front flap is usually held by the at least one retaining pin.

This embodiment has the advantage that the at least one rotation pin can form at least one swivel joint with the at least one retaining pin if the at least one retaining pin is a circular cylinder, in particular a circular cylinder with a radius that is essentially equal to the radius of the likewise circular-cylindrical interior of the at least is a rotation pin, and the front flap is in the end position. In this embodiment, the outer surface of the interior can correspond to the surface that rests against the at least one retaining pin.

According to a preferred embodiment, the rotation pin at least partially surrounds the retaining pin when the front flap is in the end position. This forms the swivel joint. In a further development, the at least one rotation pin surrounds the at least one retaining pin on at least one section in the axial direction so that the at least one rotation pin each over an angle of at least 135 °, preferably 180 °, particularly preferably more than 185 ° on the lateral surface of the at least one retaining pin is essentially applied when the front flap is in the end position. This has the advantage that the front flap is held in the largest possible swivel angle range by the at least one rotation pin, in particular when the at least one retaining pin is arranged horizontally and the weight of the front flap is held vertically downwards by the at least one rotation pin, radially onto the at least one retaining pin works.

It can be particularly advantageous that the at least one rotation pin surrounds the at least one retaining pin on at least one section in the axial direction in such a way that the at least one rotation pin over an angle of 180 ° to 185 °, or between 185 ° and 200 ° and or more than 200 ° essentially rests on the lateral surface of the at least one retaining pin when the front flap is in the end position. This makes it possible that the at least one rotation pin can only be removed therefrom in the radial direction of the axis of the at least one holding pin when the at least one rotation pin is deformed, which generates a holding force that holds the at least one rotation pin on the at least one holding pin , or that the at least one rotation pin is clamped onto the at least one retaining pin.

In an advantageous embodiment, the at least one retaining pin essentially has the shape of a circular cylinder. This shape is advantageous in forming a swivel joint. The at least one rotation pin particularly preferably has an interior space which essentially has the shape of a jacket of a circular cylinder with an opening in the radial direction over the length of the rotation pin. The opening can also be drawn as a slit or gap. In this embodiment, the rotation pin can also be referred to as a slotted sleeve. A retaining pin, which is parallel to the axis of the rotation pin, can be pushed through the opening, which extends over the length of the rotation pin, by moving perpendicular to the axis over the opening into the interior of the rotation pin. The width of the gap preferably corresponds to the diameter of the retaining pin or is greater than the diameter of the retaining pin.

This enables the at least one holding pin to be moved through the lateral opening of the at least one rotation pin in the negative radial direction of the axis of the at least one holding pin into the center of the at least one rotation pin. This also makes it possible that the at least one retaining pin can be moved out of the at least one rotation journal through the lateral opening of the at least one rotation pin in the radial direction of the axis of the at least one retaining pin.

According to one embodiment, at least one link guide forms an elongated recess on the body, which in its upper region extends essentially vertically or obliquely vertically from top to bottom. By obliquely vertical, obliquely horizontal, obliquely above and obliquely below are to be understood directions which differ from the vertical direction, horizontal direction, the upward direction and the downward direction by less than 45 °, respectively. In an advantageous development, the at least one link guide has an opening on its upper side. It is advantageous if the width of the at least one link guide is increased at this opening, which can facilitate insertion of the at least one rotation pin into the at least one link guide.

An advantage of the embodiment in which the link guide runs vertically or obliquely vertically downwards in the upper area is that the at least one rotation pin can be moved along the elongated course of the at least one link guide. In addition, there is a further advantage that the front flap must first be lifted upwards or obliquely upwards in order to remove the at least one rotation pin from the at least one link guide. As a result, accidental removal of the front flap and the resulting risk of the front flap falling down are made more difficult or prevented. The upper area of the sliding block guide can be the upper 30% of the sliding block guide, in a preferred embodiment the upper 50% of the sliding block guide, and / or the upper 3 cm. The link guide advantageously has a width that is greater than or equal to the diameter of the at least one rotary pin. It can also be advantageous if the at least one link guide has a width that is not significantly greater than this diameter of the at least one rotary pin.

According to a preferred embodiment, the at least one link guide has a deflection in its middle or lower area, which can be 90 °, for example, and the at least one retaining pin is arranged in the area of the deflection or offset to the side thereof. The lower area of the link guide can be the lower 30% of the link guide, in a preferred embodiment the lower 50% of the link guide, and / or the lower 3 cm. The middle area of the link guide is the area that lies between the upper and lower area. In another Embodiment, the 90 ° deflection has an angle that is approximately 90 °, in particular between 80 ° and 100 °, or between 45 ° and 135 °.

One advantage of providing a deflection in the slotted guide is that the front flap is at least partially held at the deflection by the at least one slotted guide, since a slotted guide that initially runs vertically runs essentially horizontally after the deflection, or since a slotted guide that initially runs vertically runs obliquely vertically after the deflection runs essentially obliquely horizontally. Thus, the at least one rotation pin can be held at least partially on the edge of the horizontally or obliquely horizontally extending link guide. This embodiment prevents the front flap from falling down, since the rotation pin and thus the front flap can only move as far as the deflection by weight. Any further movement requires a force to be applied by the user.

It is advantageous if the side opening, in particular the slot of the at least one rotation pin, points downwards or diagonally downwards in a pivoted position of the front flap of the extractor device intended for operation, as this ensures that the at least one retaining pin does the Weight of the front flap holds.

In the assembly position, i.e. in the pivoting position of the front flap while the front flap is being moved into the end position, it can be advantageous if the side opening of the at least one rotation pin points in a horizontal or oblique horizontal direction, as this results in the pivoting position of the front flap in the Assembly differs considerably from the advantageous pivoted position of the front flap during operation, in which the lateral opening of the at least one rotation pin points downwards or obliquely downwards. The deviation can be essentially 90 ° or approximately 90 °. If, for example, the pivot position provided for the operation is determined so that the front flap is in a vertical position, the pivoting position of the mounting position can be selected so that the front flap is in a horizontal position. This is advantageous because the front flap in the pivoted positions for normal operation, such as a closed position, an open position or a cleaning position, cannot be moved from its end position.

According to one embodiment, the at least one rotation pin is arranged in such a way that the front flap can only be moved out of its end position or into its end position when the front flap is in an assembly position which essentially has a predetermined angle or angular range of the front flap to the body in a vertical direction Direction is. This can be ensured in particular by a suitable arrangement of the slot on the rotary pin. Only when this slot is aligned with the retaining pin can the latter be introduced into the rotation pin through the opening or moved out of it.

In a further development, the pivoting position of the front flap in the assembly position is a pivoting position that is not assumed in normal operation, such as a closed position, an open position or a cleaning position. This can be advantageous because the front flap cannot be moved out of its end position during normal operation.

In an advantageous embodiment, the mounting position is the pivoting position of the front flap, which is defined by the angle of the front flap to the body in vertical weighting, in which the lateral opening of the at least one rotation pin essentially points in the direction of the elongated course of the at least one link guide.

If the front flap is in the end position, but not in the assembly position, the at least one swivel joint, which is formed from the at least one retaining pin and the at least one rotation pin, can, together with the at least one link guide, the front flap in all degrees of translational freedom and in all degrees of freedom of rotation , with the exception of a rotation around the axis of rotation of the at least one swivel joint.

If the front flap is in the end position and also in the assembly position, the front flap can, in a preferred embodiment, be moved in the direction of the elongated course of the at least one link guide and so out of the End position are moved, for example, to expand the front flap. The at least one rotation pin is removed from the at least one retaining pin through the lateral opening of the at least one rotation pin.

If the front flap is not in the end position, but in the assembly position, then in a preferred embodiment the front flap can be moved in the direction of the elongated course of the at least one link guide and thus moved into the end position, for example to install or assemble the front flap . The at least one rotation pin is placed on the at least one retaining pin through the lateral opening of the at least one rotation pin.

In an advantageous development, the at least one retaining pin is removably attached to the body. In an advantageous development, the at least one link guide has an opening on its underside or is continuous downwards.

This has the advantage that if the at least one retaining pin is not attached to the body, the front flap is not held by the at least one link guide, but is moved further down through the at least one link guide and out of the lower opening. Thus, the front cover can be prevented from being incorrectly attached to the body.

In an advantageous embodiment, the body comprises at least one console element which has the at least one link guide. The at least one bracket element preferably protrudes laterally further than the rest of the housing or the rest of the body. This has the advantage that the at least one link guide can be arranged on the upper side or on an upper edge of the at least one bracket element and the upper opening of the at least one link guide is thus arranged on the protruding upper edge of the at least one bracket element. It can also be advantageous that the at least one link guide extends over the side of the at least one bracket element from top to bottom and the lower opening of the at least one link guide is thus arranged on the protruding lower edge of the at least one bracket element.

According to one embodiment, the front flap comprises a front panel, in particular a glass panel, and at least one carrier element, the at least one carrier element being firmly connected to the front panel and having the at least one rotation pin.

The use of a front panel, especially a glass panel, can be particularly advantageous in the case of the holding device for a front flap described here, since the further securing through the at least one link guide additionally prevents the front flap from falling down and the risk of the front panel breaking or damage from the Front panel, thus additionally reduced or prevented by falling down. The use of a carrier element also has the advantage that it can advantageously be connected to the front plate and can encompass the at least one rotary pin in a simple manner, for example monolithically. The carrier element can for example be made of plastic or light metal, for example aluminum, and in particular be injection molded.

According to one embodiment, the front flap further comprises at least one securing lever which can be in an open state and in a closed state, the at least one securing lever being arranged adjacent to the at least one rotation pin in such a way that it allows a translational movement of the at least one rotation pin relative to the at least one retaining pin at least inhibits, preferably prevented, when the safety lever is in the closed state. The securing lever can, for example, be pivotably attached to the carrier element of the front flap. The safety lever has the advantage that the front flap is protected against unintentional unhooking by an additional safety mechanism.

The at least one safety lever can be adapted so that part of the at least one safety lever rests against the lateral opening of the at least one rotation pin and thus prevents the at least one retaining pin from moving out of the at least one rotation pin when the at least one safety lever is in the closed state .

According to one embodiment, the at least one safety lever automatically moves into the closed state when the front flap is in the end position. This movement can be generated, for example, by a pretensioned spring element. This has the advantage that the front flap is automatically secured by the at least one safety lever after the front flap has been moved into the end position during installation.

In one embodiment, the at least one safety lever has an arm, the end of which rests against the at least one rotation pin and thus prevents the at least one retaining pin from moving out of the at least one rotation pin when the at least one safety lever is in the closed state. In a further development, the at least one safety lever can be put into an open state by applying a force, for example by pressing, on the side of the arm. In an advantageous embodiment, the arm is elastically returned by a restoring force when the force no longer acts on the at least one safety lever, in particular when the front flap is in the end position. This can be achieved by a return spring or an elastic part of the at least one safety lever. The automatic movement of the at least one safety lever during assembly can be generated in that the at least one retaining pin switches the at least one safety lever to the open state before reaching the end position, for example laterally on an arm of the at least one safety lever. After the front flap has reached the end position, the force on the arm can be removed and the at least one safety lever automatically switches to the closed state by a restoring force. The removal of the force when the end position is reached can be achieved, for example, in that the at least one retaining pin initially runs obliquely along the arm of the at least one safety lever and presses it into the open state. At the same time as the end position is reached, the retaining pin can cross the end of the arm on which, as a result, there is no longer any force from the retaining pin and the latter thereby switches back into the closed state.

In an alternative embodiment, the at least one safety lever is designed in such a way that it can only be opened by using a tool, or alternatively not at all, can be switched to the open state and thus acts as a dismantling lock. This can be achieved by a safety lever in the form of a snap.

According to one embodiment, an extractor device is an extractor hood, in particular a sloping hood. In this embodiment, the front flap can be used, for example, to cover filter elements that are arranged in an inclined flow surface of the extractor hood. The front cap is preferably attached to the body in the upper area in the case of an inclined sheave. Extractor hoods, and in particular angled food, are usually installed at a distance above the hob. Front flaps must be securely attached to these extractor devices, and consequently the holding device described here for a front flap is particularly favorable, since the further securing provided by the at least one link guide additionally prevents the front flap from falling down.

Detailed description of preferred exemplary embodiments

Preferred exemplary embodiments are described below with reference to the figures. Identical, similar or identically acting elements are provided with identical reference symbols in the different figures, and a repeated description of these elements is in some cases dispensed with in order to avoid redundancies.

Figure 1 shows a schematic perspective rear view of an embodiment of an extractor device 100 according to the invention with the front flap 200 open. The front flap 200 is shown here in a sectional view. In the embodiment shown, the extractor device 100 comprises a body 300 and a console 310 attached to the upper part of the body 300. In FIG Figure 1 the front flap 200 is pivoted forward, that is, it is in the open state.

In Figure 2 is the extractor device 100 according to Figure 1 shown with the front flap 200 in the closed state.

In Figure 3 a perspective sectional view of an extractor hood 100 with a mounted and closed front flap 200 is shown schematically. The front flap 200 comprises a front plate 210 made of glass, which is also referred to as a front pane, and two carrier elements 220. Only the right carrier element 220 is shown in this figure. The left support element 220 is designed mirror-symmetrically and is arranged mirror-symmetrically on the left side of the extractor hood 100 or the body 300 of the extractor hood 100. The right support element 220 comprises the right rotation pin 230, which is monolithically connected to the support element 220. The right support element 220 and the right rotation pin 230 consist in this embodiment of a plastic. The part of the rotation pin 230 which points to the body 300 has a cylindrical shape with a base in the form of a U-shaped arc. Inside, the rotation pins 230 have a cavity that is in the shape of a circular cylinder. In the circumferential direction, the rotation pin 230 has an opening which extends over the length of the axis of the circular cylinder and connects the interior space 232 to the outside. This opening forms the lateral opening of the rotation pin 230 and points in a direction which is parallel to the front plate 210. The lateral opening and the circular cylindrical cavity surround the interior space 232 of the rotation pin 230.

The extractor hood 100 also has a body 300 which has a console element 310 made of plastic, which has a link guide 320. The link guide 320 forms a lateral, elongated indentation which is provided on the side of the body 300. The slotted guide 320 has an upper opening which is larger than the rest of the slotted guide 320. This makes it easier to insert the rotation pin 230 into the slotted guide 320. The slotted guide 320 initially runs obliquely downwards, then has a 90 ° deflection 322 and finally runs again diagonally downwards and also has an opening on its underside. In addition to the 90 ° deflection 322, a retaining pin 330 made of metal is arranged, which has the shape of a circular cylinder of the rotation pin 230, the axis of which points to the right side. The metal pin 330 protrudes from the console element 310, through the link guide 320 and laterally over it. In the Figure 1 only the right link guide 320, the right retaining pin 330, and the right side of the console element 310 are shown. On the left side of the extractor hood 100 there is also a mirror-symmetrical left link guide 320, a left retaining pin 330, and a left side of the console element 310.

The rotation pins 230 protrude into the respective link guides 320 so that the rotation pins 230 cannot be moved laterally, in particular transversely to the elongated course of the link guide 320, out of the link guide 320.

The front flap 200 is in Figure 1 in the end position in which the rotation pin 230 and the metal pin 330 form a swivel joint in that the rotation pin 230 partially surrounds the metal pin 330. The circular cylindrical In the end position, the metal pin 330 is located in the circular cylindrical interior 232 of the rotary pin 230, the diameters of the two cylinders being essentially the same. The metal pin 330 and the rotation pin 230 thus form the swivel joint. The rotation pin 230 cannot be moved in any direction relative to the metal pin 330: to the left, the front side of the right rotation pin 230 prevents movement, since the front side of the rotation pin 230 hits the inner wall of the link guide 320; to the right, the end face of the left rotation pin 230 prevents movement, since this end face abuts the inner wall of the left link guide 320; a movement of the rotation pin 230 backwards / upwards, backwards / downwards and front / downwards prevents the interaction of the rotation pin 230 with the retaining pin 330; and a forward / upward movement, i.e. the movement that would correspond to moving the retaining pin 330 out through the lateral opening of the rotary pin 230, is prevented by the rotary pin 230 hitting the link guide 320 in this direction, among other things. The only degree of freedom of the rotation pin 230 is a rotation about the axis of the retaining pin 330, which enables the front flap 200 to be pivoted or opened and closed.

Ultimately, the front flap 200 also includes a right and left securing lever 240. In FIG Figure 1 only the right locking lever 240 is shown. The left securing lever 240 is arranged in mirror symmetry on the left part of the carrier element 220. The securing lever 240 is pivotably arranged on a pin of the carrier element 220 and has an arm which points in the direction of the lateral opening of the rotation pin 230 and an elastic arm which points obliquely in the direction of the front disk 210 and has the function of a return spring.

The safety lever 240 is in the closed state, in which the arm is arranged such that the front side of the arm rests against the lateral opening of the rotation pin 230 and thus a movement forwards / upwards, i.e. a movement that prevents the retaining pin 330 from moving out by the lateral opening of the rotation pin 230 would be prevented. The safety levers 240 can be brought into the open state by a force which acts laterally on the arm in this pivoting position of the front flap 200 from above / behind. The arm swivels around the pin of the carrier element 220 in the direction of the front pane 210 and the front of the arm moves from the lateral opening of the rotation pin 230 path. The elastic arm in turn counteracts the applied force, so that the safety lever 240 automatically switches to the closed state when there is no longer any force on the arm.

Figure 4 FIG. 12 shows a schematic perspective sectional illustration of the extractor hood 100 from FIG Figure 3 with the difference that the front flap 200 is in the assembly position. The mounting position in this embodiment is fixed at an angular position between the front pane 210 and the front side, in particular the front panel, of the console element of approximately 90 °. This has the advantage that a particularly simple and intuitive assembly or disassembly is possible.

Since the safety lever 240 is in the closed state, the rotation pin 230 cannot be moved in any direction relative to the metal pin 330. If the securing lever 240 were in the open state, the front flap 200 could be moved backwards / upwards from its end position, since the link guide 320 at the location of the retaining pin 330 runs in the same direction as the direction from the lateral opening of the rotation pin 230 points into the center of the rotation pin 230.

Figure 5 FIG. 12 shows a schematic perspective sectional illustration of the extractor hood 100 from FIG Figure 4 which is currently being assembled, with the front flap 200 not (yet) in the end position. The rotation pins 230 are located in the upper section of the link guides 320. The front flap 200 is also in the assembly position. In this state, the front flap 200 can be moved backwards / downwards or forwards / upwards. For the assembly, the front flap 200 can be moved backwards / downwards, so that the rotation pins 230 initially move along the elongated course of the link guide 320 up to the 90 ° deflection. During this movement, before the rotation pin 230 reaches the 90 ° deflection, the retaining pin 330 presses laterally on the arm of the safety lever 240, so that the latter switches into the open position. This is in Figure 6 shown schematically. The front flap 200 can then be moved forwards / downwards in order to move the front flap 200 into the end position. The rotation pins 230 are pushed onto the respective retaining pins 330. As soon as the front flap 200 has reached the end position, there is no longer any force acting on the securing lever 240 due to the retaining pin 330, so that the latter snaps back into the closed state.

In Figure 7 FIG. 14 is a schematic perspective view of the rear of the front door 200 of FIG Figure 1 shown. The front flap 200 consists of a front plate 210 and two interconnected support elements 220. In this view, both the right rotation pin 230 and the left rotation pin 230, as well as the inner spaces 232 of the rotation pins 230, which each have the shape of a jacket of a circular cylinder, with a Have opening in the radial direction over the length of the axis, shown. The carrier element 220 and the two rotation pins 230 are made from one piece and firmly connected to the glass pane 210. In this view, the right and the left securing lever 240 are also shown. In the event of dismantling, the two safety levers can be switched to the open state by pressing, for example with your fingers.

In the following, the method for attaching to and removing the front flap from a body of an extractor hood device is described again with the aid of the individual steps.

1. (a) Einführen des mindestens einen Rotationszapfens in die mindestens eine Kulissenführung;
2. (b) Bewegen des mindestens einen Rotationszapfens entlang der mindestens einen Kulissenführung; und
3. (c) Bewegen der Frontklappe in die Endposition, wobei sich die Frontklappe dabei in einer Montageposition befindet.

The method of fastening comprises at least the following steps:

1. (a) Introducing the at least one rotation pin into the at least one link guide;
2. (b) moving the at least one rotation pin along the at least one link guide; and
3. (c) Moving the front flap into the end position, the front flap being in an assembly position.

This method is particularly advantageous because no tool is required to attach the front flap. It is also advantageous that a single person, in particular the end user, can attach the front flap. This saves costs and can also facilitate the assembly of the extractor device, since the body can initially be assembled without a front flap. The front flap can be attached after the body has been assembled.

The introduction of the at least one rotary pin can be achieved by moving the front flap in such a way that the at least one rotary pin is moved to an upper opening of the at least one link guide, where it is inserted into it.

In an advantageous embodiment, the at least one rotation pin is moved essentially downwards or obliquely downwards in step (b). The movement can be brought about by moving the front flap accordingly.

In an advantageous embodiment, the at least one rotation pin is pushed onto the at least one retaining pin in step (c).

In an advantageous embodiment, in step (c) the front flap is moved forwards or obliquely forwards and / or in a direction which is essentially perpendicular to the direction of movement of the at least one rotation pin in step (b). The at least one rotation pin can be moved in the same direction and pushed onto the at least one retaining pin, the lateral opening of the at least one rotation pin pointing in the direction of movement. The proposed direction of movement when reaching the end position in the direction of movement can lead to an advantageous direction of the lateral opening of the at least one rotation pin relative to the front flap.

In an advantageous embodiment, in step (c) the mounting position of the front flap is a predefined, vertical pivoting position. In an advantageous embodiment, the front flap has an angle to a front side of the body between 60 ° and 120 °, preferably between 80 and 100 °, in the assembly position. In an advantageous embodiment, the front flap has an angle to the vertical direction between 60 ° and 120 °, preferably between 80 and 100 °, in the assembly position. In case of doubt, the angles are to be related to the alignment of a front panel of the front flap.

In an advantageous embodiment, the method comprises a further step after step c):
(d) Independent switching of the at least one safety lever into the closed state.

This is advantageous because the automatic switching of the at least one safety lever can prevent undesired movement of the front flap out of the end position.

• (e) Drehen der Frontklappe in eine Montageposition;
• (f) Bewegen der Frontklappe aus der Endposition, wobei sich die Frontklappe dabei in der Montageposition befindet;
• (g) Bewegen des mindestens einen Rotationszapfens entlang der mindestens einen Kulissenführung; und
• (h) Entfernen des mindestens einen Rotationszapfens aus der mindestens einen Kulissenführung.

A method for removing a front flap from a body of an extractor hood device is also proposed, the method comprising the steps:

• (e) rotating the front door to a mounting position;
• (f) moving the front flap out of the end position, the front flap being in the assembly position;
• (g) moving the at least one rotation pin along the at least one link guide; and
• (h) Removing the at least one rotation pin from the at least one link guide.

This has the advantage that the front flap can easily be removed from the body. It is also advantageous that a single person, in particular the end user, can remove the front flap.

In an advantageous embodiment, in step (e) the mounting position of the front flap is a predefined, vertical pivoting position. In an advantageous embodiment, the front flap has an angle to a front side of the body between 60 ° and 120 °, preferably between 80 and 100 °, in the assembly position. In an advantageous embodiment, the front flap has an angle to the vertical direction between 60 ° and 120 °, preferably between 80 and 100 °, in the assembly position. In case of doubt, the angles should be related to the alignment of a front panel of the front flap. The axis of rotation can be defined by the position of the at least one rotation pin, in particular the axis can be the axis of the at least one swivel joint that forms the at least one rotation pin and the at least one retaining pin.

In an advantageous embodiment, the at least one rotation pin is removed from the at least one retaining pin in step (f). In an advantageous embodiment, the front flap is moved backwards or obliquely backwards in step (f).

This can have the advantage that the at least one rotation pin is moved in the same direction and is removed from the at least one retaining pin in this direction, the lateral opening of the at least one rotation pin pointing in an advantageous direction.

In an advantageous embodiment, the at least one rotation pin is moved essentially upwards or obliquely upwards in step (g) and / or in a direction that is essentially perpendicular to the direction of movement of the at least one rotation pin in step (f). The movement can be brought about by moving the front flap accordingly.

The removal of the at least one rotation pin from the at least one link guide can be achieved in that the front flap is moved in such a way that the at least one rotation pin is moved out of an upper opening of the at least one link guide.

In an advantageous embodiment, the method comprises a further step between step e) and step f):
e1) Switching the at least one safety lever into the open state.

By switching the safety lever to the open state, the front flap can be moved out of the end position. This additional step has the advantage that an undesired movement of the front flap out of the end position can be prevented.

In one embodiment, the at least one securing lever has an arm, the end of which rests against the at least one rotation pin and thus a moving out of the at least one retaining pin from the at least one rotation pin prevents when the at least one safety lever is in the closed state. By applying a force to the side of the arm, for example by pressing, in particular with a finger, the at least one safety lever can be put into an open state.

As far as applicable, all the individual features that are shown in the exemplary embodiments can be combined with one another and / or exchanged without departing from the scope of the invention.
