Description

Edge limitation for cover plate of an extractor hood and

Hood

The invention relates to a deckle for a cover plate of a vapor shield of a fume hood and an extractor hood with deckle. In particular, the invention relates to an eat, preferably a Wandesse or Inselesse.

In the case of extractor hoods, which are designed as food, the top of the hood of the extractor hood is often used by the users of the extractor hood as a storage area for spices and the like. In order to prevent falling down of these items or to ensure safe placement of these items, it is known to provide extractor hood a railing, which is also referred to as a railing and which limits the shelf. This railing must be attached to the top of the screen. The attachment is usually by means of support feet which are attached to the top of the screen, in particular screwed to it. The disadvantage of this embodiment of a rail is that the top of the screen is no longer accessible from the front and thus the cleaning of the top is difficult.

The invention has for its object to provide a way by which the advantages of the prior art can be used, in particular to create a demarcation of a storage area, and yet the top of the screen of the hood is easily accessible.

The object is achieved according to a first aspect by a deckle for a cover plate of a vapor shield of a fume hood, which consists of at least one edge element and at least one fastening device for attachment to the cover plate. The edge boundary is characterized in that the fastening device is connected to at least one of the edge elements of the edge boundary via a hinge.

By providing a joint, the edge boundary relative to the fastening device and thus, after attachment to the cover plate of the vapor shield, relative to the cover plate pivoted or tilted or be worked out. In this way, the access to the cover plate can be ensured even after mounting the deckle.

Particularly preferably, the fastening device is a clamping device. This facilitates the installation of the edge boundary on the cover plate. It is the user of the hood in particular allows the edge limitation without a separate tool, such as screwdrivers and the like, to attach to the hood. Furthermore, the edge boundary in this type of fastening device can also be removed at any time without fastening elements remaining on the cover plate. This would be the case with a screw in which would remain after removing the deckle a screw hole in the cover plate and would reduce the visual impression of the cover plate. Furthermore, a clamping device with respect to the choice of material of the cover plate is advantageous. The clamping device can also be attached to brittle material, such as glass or plexiglass, since processing of the cover plate, in particular the introduction of a screw hole can be omitted.

Preferably, the fastening device and a part of the joint are provided on a common component of the edge boundary. By this one-piece design, on the one hand, the number of components necessary for the assembly can be limited and on the other hand, a secure hold of the deckle on the cover plate are guaranteed even when pivoting the edge elements. Furthermore, the stability of the edge boundary in the normal state, that is, when it is not pivoted, increased.

The part of the joint which is connected to the fastening device can be arranged above the fastening device and in projection on the fastening device centered to the fastening device. As a result, leverage forces that could occur in a displaced to the fastening device arranged joint, avoided. The part of the joint, which is provided with the fastening device on a common component, is preferably a pipe piece. In this way, a peripheral element or a coupling element can be inserted into the pipe section and so the joint can be formed. The provision of a separate hinge pin and connecting the bolt with the edge element can be omitted. In the pipe section is preferably a passage opening for a securing element of the joint is provided. This can represent, for example, a pen. Through the passage opening can be introduced after the introduction of the edge element or a coupling element in the pipe section of the pin and brought into contact with the edge element or coupling element. Slipping out of the pipe section can be avoided. The securing can be done by adhesion or preferably by engagement of the securing element in a provided for this purpose in the edge element or coupling element groove or groove.

Preferably, the edge elements are releasably connected to each other via coupling elements. This detachable connection allows disassembly of the deckle by the user and allows a small packaging volume in the delivery and storage of the deckle. In addition, by providing coupling elements, the shape of the edge elements can be kept simple. The edge elements may for example be straight elements and the coupling elements may be formed as corner elements. In addition, this multi-part construction has the advantage that different elements can be made of different materials. Thus, the edge elements made of metal, preferably aluminum or stainless steel, can be produced, whereas the coupling elements may be made of plastic, for example. By this combination of materials, a stability can be created by the edge elements and the coupling elements can be given a flexibility by the example, a connection by means of locking devices is possible. Furthermore, the multi-part structure of the deckle, for example, for use in island food advantage because the boundary of this can also be retrofitted, which would not be possible with a one-piece deckle. Finally, part of the

Coupling serve to form the joint by this is joined together with a further edge part with another part of the joint, in particular a piece of pipe.

According to one embodiment, the edge elements are rods, preferably tubes. But it is also possible to use as edge elements planar elements, such as metal strips or glass strips. These can be vertically aligned and rest in the mounted state with their lower edge in the edge region of the cover plate.

In particular, when the edge elements are rods or tubes, the connection between the edge element and the coupling element preferably has an anti-rotation lock. This anti-rotation serves on the one hand to increase the security when handling the deckle. When folding up or swiveling the edge boundary with respect to the cover plate, the edge element can not slip away from the user by twisting with respect to the coupling element. Furthermore, a support device is preferably provided when using a linkage as edge elements, which allows the

To arrange linkage at a distance to the cover plate. The support device may be provided on the one hand on the fastening device. In this case, the support device preferably comprises a fastening device and a part of the joint. Preferably, a support device is also provided on at least one further point of the edge boundary on the linkage. As a result, the weight of the deckle is distributed over several points and leverage on the fixture can be avoided. By providing an anti-rotation can be ensured in this embodiment that the support devices always have in the direction of the cover plate. The rotation can be realized for example by matching cross-sections of the edge elements and the coupling elements.

According to a further aspect, the invention relates to an extractor hood, which has a Wrasenschirm with a cover plate and at least one attached to the cover plate deckle, which extends vertically increased at least three sides of the cover plate relative to the cover plate. The extractor hood is characterized in that the edge boundary is pivotally connected to the cover plate.

In this way, a storage area can be limited to the cover plate and the cover plate are made accessible to the user by pivoting the deckle. As sides of the cover plate on which the edge elements extend, the edge region of the cover plate is designated. The edge elements can in this case run directly on the edge itself or offset inwards on the surface of the cover plate. If the extractor hood is a wall unit, the three are

Edge regions of the cover plate on which the edge boundary preferably extends the front side and the two sides. In this case, the deckle on the wall-facing side of the cover plate is pivotally connected to the cover plate. In an island fair, however, the edge boundary may extend at the front and half of the sides and be pivotally connected there to the cover plate. In this case, a second deckle may be provided, which extends at the back of the cover plate and the rear halves of the sides of the cover plate and is also pivotally connected to the cover plate in the middle of the sides. Even with island food, but it is possible to provide only one edge boundary, which limits the entire cover plate at the edge regions.

The pivotal connection between the deckle and the cover plate can be realized via a hinge, which is preferably provided on the edge boundary. For wall meals, preferably two hinges can be provided at the rear corners of the cover plate. For island food, a single joint may be sufficient.

The deckle is preferably connected to the cover plate only on one side of the cover plate. As a result, on the one hand, the pivoting of the edge boundary against the worktop allows and on the other hand, the entire cover plate accessible to the user when folding the deckle except the attachment device of the deckle, which is provided on one side of the cover, which is particularly beneficial for cleaning purposes ,

Preferably, the edge boundary is connected to the cover plate via a clamping device. This type of attachment allows easy installation of the deckle. The clamping device is preferably a part of the deckle so that it can be easily pushed onto the cover plate and positioned. Particularly preferably, the clamping device is designed in one piece with a supporting device for the edge limitation. With this structure, the grip of the deckle can be improved. In addition, the number of for assembly minimizes required components and thus simplifies the logistics in the packaging and delivery of the deckle.

According to one embodiment, the cover plate is arranged at a distance from the upper side of the vapor shield. This embodiment is in particular in connection with a clamping device as a fastening device for the edge boundary of advantage, since in this case a gripping an edge of the cover plate is made possible by the clamping device without the clamping device must engage in the Wrasenschirm or a separate recess on the vapor shield are provided for this purpose got to. By the cover plate is spaced from the vapor shield, this can also be designed as a completely separate component and separately from the

Extractor hood can be removed. In this way, the assembly and disassembly of the deckle is further simplified and also the cleaning of the cover plate and also the top of the screen is simplified. The cover plate may be inserted in this embodiment in a holder, such as a groove on the cowling duct of the hood. In addition, the cover plate may be formed in this case of a different material than the vapor shield. For example, glass or Plexiglas can be used, which improves the visual appearance of the hood and also minimizes the risk of damage to the cover plate by scratching.

According to a further embodiment, the vapor shield is horizontally displaceable separately from the cover plate. In particular, in this embodiment, the provision of a deckle is of particular importance, so that accidental parking of articles on the top of the vapor shield in the extended state can be avoided. In addition, in the extended state, part of the

Cover plate, especially the lateral rear edge, visible from below to the viewer. If the cover plate consists of a transparent material, it is therefore important to provide the possibility of cleaning the entire cover plate, which is realized according to the invention by the pivotable edge boundary.

The provided on the hood peripheral boundary preferably represents an above-described edge boundary according to the invention and in particular comprises a joint, via which the pivoting of the edge boundary is made possible. Advantages and features that will be described with regard to the boundary will apply, as applicable, corresponding to the cooker hood and vice versa.

Further features and advantages of the invention will become apparent from the following description of the accompanying figures. Show it:

FIG. 7 shows a perspective partial view of the rear area of the edge boundary according to FIG. 1.

FIG. 1 shows an extractor hood 1 according to the invention with an embodiment of the edge boundary 2 according to the invention. The extractor hood 1 has a screen 3, on the upper side of a cover plate 4 is provided. In the illustrated embodiment, the cover plate 4 is located at a distance above the top of the screen 3. At the front of the screen controls 5 and an actuator 6 are provided. About this actuator 6, the screen 3 can be moved in the horizontal direction, in particular with respect to the channel 7 of the hood 1, with which the screen 3 is connected to be pulled out. The cover plate 4 arranged above the screen 3 is inserted on the channel 7 in a groove 8 and thus fixed. When moving the screen 3, the cover plate 4 is not moved, but remains in the position shown.

On the cover 4, the edge boundary 2 of the invention is provided. This is in the illustrated embodiment, a rearwardly open rail and consists of three edge elements 9, which have the form of tubes. The edge elements 9 are connected to each other via coupling elements, which are designed here as corner elements 10. In the rear region of the edge boundary 2, these two support elements 1 1, of which in Figure 1 only one can be seen. The lower portion of the support element 1 1 serves as a fastening device 12 for attachment of the edge boundary 2 on the cover plate 4. The upper portion of the support element 1 1 represents a part of a joint 14, via which the edge boundary 2 can be pivoted relative to the cover plate 4. The possible tilting movement of the edge boundary 2 is indicated by the arrow K in FIG. At the front of the edge boundary 2, the front edge element 9 is held by two supports 13. The supports 13 are on the cover plate 4, but are not connected to this.

By simply swinging up the edge boundary 2, which can be performed with one hand, the edge boundary 2 is only in the area of

Fastener 12 with the cover 4 in contact. The remaining surface of the cover 4 is freely accessible to the user and can be cleaned over a large area.

The construction of the edge boundary 2 will be explained in more detail below with reference to FIGS. 2 to 7.

FIG. 2 shows a corner element 10. This consists of the corner region 15, as well as adjoining legs 16, which have a smaller diameter than the corner region 15 and can thus be introduced into the ends of the edge elements 9 designed as tubes. In the region of the free ends of the legs 16, the corner element 10 has a rectangular cross-section 17. The rectangular cross-section 17 is adjoined in the direction of the corner region 15 by a taper, through which a groove 18 is formed. In this groove 18 protrudes from the Rectangular cross-section 17 from a web 19 in, on the outside of a locking lug 20 is provided. The web 19 is connected at only one end to the rectangular cross-section 17, so that it is flexible and in particular inwardly, that can be bent in the direction of the axis of the leg 16. The locking lug 20 has a wedge shape, wherein the height of the latching lug 20 increases from the rectangular cross-section 17 to the corner region 15 out. This form of locking lug 20 is the lighter

Insertion in a locking receptacle. Between the groove 18 and the corner region 15, the leg 16 has a round cross-section with a reduced diameter relative to the corner region 15.

The legs 16 of the corner element 10 can in the ends of the elongate edge elements

9 are introduced. A partial view of one end of an edge element 9 is shown in FIG. This has the shape of a pipe. At a distance from the axial end of the edge element 9, a rectangular inner cross-section 21 is provided. Between this rectangular inner cross section 21 and the axial end of the edge element 9, a detent hole 22 is inserted into the wall of the edge element 9. In the mounted state, the detent holes of the edge elements 9 are preferably inward, that is to say in the direction of the trim channel 7 of the extractor hood 1.

When inserting the corner element 10 into the end of a peripheral element 9, the rectangular inner cross section 21 comes into contact with the rectangular cross section 17 of the corner element 9, whereby rotation of the edge element 9 with respect to the corner element 10 is prevented. The provided on the corner element 10 locking lug 20 comes into engagement with the locking hole 22 in the edge element 9 and slipping out of the corner element

10 from the edge element 9 is prevented.

In this way, a positive connection between the edge elements 9 and the corner elements 10 is made possible, which can be solved by pressing the locking lug 20 in the locking hole 22, if necessary.

The joining of corner element 10 and edge elements 9 is shown in FIG. The left leg 16 of the corner element 10 is received in the left edge element 9 and the locking lug 20 protrudes through the locking hole 22 therethrough. The right leg 16 of the corner element 10 is not yet introduced into the edge element 9. In the assembled state, only the corner region 15 of the corner element 10 is visible. The legs 16 are surrounded by the ends of the edge elements 9. This is shown in Figure 5, in which a front corner of the deckle 2 is shown. Between the edge elements 9 and the cover plate 4 supports 13 are provided on the front. At the end of the support 13, which faces away from the edge element 9 and faces the cover plate 4, a recess 24 is provided, in which a profile 23 is received, which consists of an elastic material, such as silicone. The profile 23 protrudes beyond the lower end of the support 13, so that an immediate resting of the support 13 on the cover plate 4 is prevented and a damping when striking the edge boundary 2 on the cover plate 4 is created.

The provided in the rear region of the edge boundary 2 support elements 1 1 may have the structure shown in Figure 6. In this case, the fastening device 12 has a U-shape with a lower U-leg 25 and an upper U-leg 26, which are connected to one another via a base 27. At the lower U-leg 25, a projection 31 is provided on the upper U-leg 26 side facing. At the free end of the upper U-leg 26, a connecting web 28 connects, which carries at the top thereof a piece of pipe 29 which forms part of the joint 14. In the wall of the blank, a passage opening 30 for a pin (not shown) is introduced.

The support member 1 1 is mounted in the manner shown in Figure 7. In the pipe section 29, a leg 16 of a corner element 10 is introduced from the side. By the leg 16 and the pipe section 29 thus a joint 14 is formed, which allows a rotation about the axis of the pipe section 29. In order to prevent slipping out of the leg 16 from the pipe section 29, a pin is guided through the passage opening 30, which extends into the groove 18 in the leg 16 and thus prevents axial movement of the leg 16 in the pipe section 29. The fastening device 12 is pushed from behind onto the cover plate 4 until the base 27 abuts against the outer edge of the cover plate 4. In this state, the upper and lower U-legs 25 and 26 engage around the cover plate 4 and exert a certain clamping force on them. The clamping force is reinforced by the provided on the lower U-leg 25 projection 31. One of the locking lug 20 corresponding opening is not provided in the pipe section 29, so that a rotation or tilting of the edge boundary 2 is ensured about the axis of the pipe section 29. By lacking such an opening can be used for the formation of the joint 14, a corner piece 10, which are also used for the other corners of the deckle 2. As a result, the number of different components is minimized, whereby the assembly is facilitated because mounting errors are excluded. Also the logistics for the production and packing is facilitated. There are only four identical corner elements 10, three edge elements 9, two supports 13 and two support elements 1 1 necessary for the illustrated embodiment of the invention.

Advantages of the present invention are, in particular, that a cleaning of the underlying cover plate is made possible even when mounted edge boundary or railing. For this purpose, the rail can be folded over the joint mechanism created upwards. To dampen the impact when folding down the railing on the cover plate can be provided on supports for the railing silicone profiles. By preferably provided Verrastmechanismus the corner pieces with the edge elements or linkage of the railing, it is possible to pack the railing very space-saving and to assemble them on site even by the user of the hood itself without further aids and to position on the cover plate.
