Description

The invention relates to a device for the parallel outward pivoting of a platform from a piece of furniture, in particular from a base cabinet, preferably from a kitchen base cabinet, from a folded-in, at least substantially horizontal position into a folded-out, at least substantially horizontal position, having at least two pivot arms, wherein the pivot arms can each be fixed on opposite sides of the platform and of the piece of furniture, and a connecting element arranged between the pivot arms.Furthermore, the invention relates to a connecting element for such a device.Apparatuses of the type in question are known from practice and are used, inter alia, to store kitchen appliances, for example bread clippers, blenders, etc., on a platform in a base cabinet. In order to use the kitchen appliance, the platform is moved via the device from the folded-in position, in which the platform is located within the base cabinet, into a folded-out position, in which the platform is located at least substantially at the height of the upper side of the base cabinet. It is essential here that the platform is guided in such a way that it is always at least substantially in a horizontal position, so that the kitchen appliance arranged thereon cannot slide off.In addition to the parallel pivoting of the platform, it is important in the aforementioned devices that they are sufficiently stable in order to sometimes be able to accommodate massive and thus heavy kitchen appliances securely. The devices themselves are therefore to be designed to be correspondingly massive and therefore require a relatively large installation space. Due to the restricted space available within the lower cabinet, this finally restricts the space which is available for the kitchen appliance to be accommodated. Thus, for example, kitchen appliances having an protruding height often cannot be arranged on the platform.The object of the present invention is therefore to design and further develop a device of the type mentioned at the beginning in such a way that a platform can be held and moved securely using structurally simple means and in the process the largest possible receiving space is provided on the platform. Furthermore, a connecting element for such a device is to be specified.According to the invention, the above object with respect to the device is achieved by the features of claim 1. According to this, a device for the parallel outward pivoting of a platform from a piece of furniture, in particular from a base cabinet, preferably from a kitchen base cabinet, from a folded-in, at least substantially horizontal position into a folded-out, at least substantially horizontal position, is provided with at least two pivot arms, wherein the pivot arms can each be fixed on opposite sides of the platform and of the piece of furniture and a connecting element arranged between the pivot arms, characterized in that the connecting element has two outer regions and a central region, wherein the outer regions each comprise a free end of the connecting element which faces one of the pivot arms, and wherein the central region is further away from the platform than the outer regions when the platform is in the folded-in position.With respect to the connecting element, the above object is achieved by the features of claim 10. Thus, a connecting element for a device according to one of claims 1 to 9 is claimed, having two outer regions and a central region arranged between them, wherein the central region is offset from the outer regions by 10 mm to 60 mm, in particular 20 mm to 50 mm, preferably 25 mm to 50 mm.In a manner according to the invention, it has first been recognized that the underlying object can be achieved by a skillful configuration of the connecting element. For this purpose, the connecting element is not straight, but is offset or set back in its central region with respect to the outer regions. This allows the central region to be more remote from the platform than the outer regions when the platform is in the folded-in position, i.e. when the platform is arranged in the furniture. This structural measure creates additional space in the central region for an object arranged on the platform, for example for a food processor. However, it is also ensured that the device is constructed in an extremely stable manner overall and thus heavier objects can also be held securely. In other words, the device according to the invention can be a pivot fitting or parallel pivot fitting, in which the connecting element is formed in accordance with the above explanations. It is to be noted that the platform, for example a wood board, does not necessarily have to be part of the device according to the invention, but may be.The connecting element according to the invention can have the features and advantages described with respect to the connecting element of the device, in particular the features of the connecting element contained in the dependent claims 2 to 9 and the following description.The expression "horizontally arranged" is to be understood within the scope of this disclosure to mean that the platform is aligned horizontally in the state arranged in a piece of furniture, for example a kitchen cupboard, so that objects can be arranged on the platform without the platform sliding down on account of an inclined position of the platform. The device is preferably designed such that the platform is always aligned at least substantially horizontally both in the folded-in position and in the unfolded position and during the transfer from the folded-in position to the unfolded position.The connecting element is advantageously designed at least in regions as a U-shaped bracket. With such a construction, it is achieved in a particularly simple manner that the central region of the connecting element is farther from the platform than the outer regions. The bracket can preferably be produced by a bending method. Furthermore, it is conceivable that the connecting element is milled from solid material, for example from an aluminum block or another material. In general, the connecting element can be manufactured from a metal, a metal alloy, a plastic or another sufficiently moldable and stable material or can comprise this.In a further advantageous manner, the connecting element can be formed from a solid tube or from a hollow tube. A solid tube has the advantage that it is particularly stable. The advantage of a hollow tube is the small amount of material, which results in a low weight of the device. The connecting element can preferably have an outer diameter of 10 mm to 20 mm, in particular of 12 mm to 18 mm, as a result of which an advantageous ratio of the size of the connecting element to the stability achieved is given.According to an advantageous embodiment, the connecting element can have an angular, in particular a quadrangular, cross section or a round cross section. The cross section of the connecting element can be selected accordingly depending on the further construction of the device.In a particularly advantageous manner, the connecting element can have an overall length of 250 mm to 700 mm, in particular of 300 mm to 500 mm. The total length of the connecting element is advantageously to be selected such that the device can be arranged in the furniture item, preferably in a kitchen cupboard, for example with a width of 600 mm, wherein it can also be dimensioned such that it can be inserted into wider or narrower furniture items.The central region can advantageously be offset from the outer regions by 10 mm to 60 mm, in particular 20 mm to 50 mm, preferably 25 mm to 50 mm. In other words, the central region deviates by the specified lengths from a straight configuration of the connecting element, such that the deviating-recessed-central region is further away from the platform when it is in the folded-in position.In a particularly advantageous manner, the central region can have a length of 150 mm to 300 mm. This creates sufficient space to also arrange larger objects or kitchen appliances on the platform. Alternatively or additionally, the outer regions can each have a length of 50 mm to 150 mm. This has the advantage that these regions are formed to be sufficiently long to achieve the necessary stability of the device.Furthermore, it is conceivable and advantageous that the ratio of the length of the middle region to the total length of the two outer regions is in the range from 0.8 to 1.2, in particular from 0.95 to 1.05, preferably 1. With such a constructional measure, a particularly stable device is created which is of an extremely small construction. The aforementioned total length of the two outer regions is composed of the sum of the lengths of the two outer regions.In a further advantageous manner, fastening elements can be arranged in order to arrange the pivot arms via the fastening elements on the platform and / or on the furniture item. This on the one hand allows the device to be securely fixed to the platform and the furniture item, and on the other hand, a simple construction allows the movement of the pivot arms necessary for the pivoting out.According to an advantageous embodiment, a receiving element can be arranged on one of the pivot arms or on both pivot arms, on or in which one of the two outer regions of the connecting element can be fixed in each case. The outer region can advantageously be introduced into the receiving element and optionally fixed with a fixing means, for example a screw. It is additionally conceivable that the outer region is inserted into the receiving element or elements according to the desired total width of the device and is fixed in this position. The device can thus be easily adapted to different widths of the furniture.Advantageously, two pivot arms can be arranged on each side of the platform, so that the device has a total of four pivot arms.There are now various possibilities for advantageously embodying and developing the teaching of the present invention. For this purpose, reference is made on the one hand to the claims subordinate to claim 1 and on the other hand to the following explanation of preferred exemplary embodiments of the invention on the basis of the drawing. In conjunction with the explanation of the preferred exemplary embodiments of the invention on the basis of the drawing, preferred embodiments and refinements of the teaching are also generally explained. The drawing shows FIG. 1 shows a schematic illustration of a perspective view of an exemplary embodiment of a device according to the invention in a folded-in position, FIG. 2 shows a schematic illustration of a front view of the device according to FIG. 1, FIG. 3 shows a sectional view of the device according to FIG. 1 in a schematic illustration, FIG. 4 is a schematic representation of a perspective view of the exemplary embodiment of FIGS. 1 to 3 in a deployed position, FIG. 5 shows a schematic illustration of a front view of the device according to FIG. 4, FIG. 6 shows a schematic illustration of a sectional view of the apparatus according to FIG. 4, FIG. 7 shows a schematic illustration of a side view of a connecting element according to the invention, FIG. 8 shows a schematic illustration of a perspective view of the connecting element according to FIG. 7, and FIG. 9 shows a schematic illustration of a further perspective view of the connecting element according to FIG. 7.FIGS. 1 to 6 show an exemplary embodiment of a device according to the invention in different representations. The device serves for the parallel outward pivoting of a platform 1 out of a piece of furniture 2, which can be designed, for example, as a kitchen cabinet. The device has on opposite sides of the platform 1 in each case two pivot arms 3, 3', 4, 4', which are connected to the platform 1 and the furniture 2. It is also conceivable that only one pivot arm 3, 4 is provided on each side of the platform. The platform 1 can be designed, for example, as a wood plate, metal plate, plastic plate or a plate made of any other material.It can furthermore be clearly seen that the platform 1 is aligned horizontally both in the folded-in position shown in FIGS. 1 to 3 and in the folded-out position shown in FIGS. 4 to 6. The same applies during the movement of the platform 1 from one position into the other. It is thus possible to arrange an object, for example a kitchen appliance, on the platform 1 and, if required, to fold it out of the piece of furniture 2 together with the latter.In order to increase the available height of the storage space on the platform 1, the connecting element 5, which connects the pivot arms 3, 3' to the pivot arms 4, 4', has a central region 6, which in the folded-in position of the platform 1 is situated further away from the latter than the outer regions 7, 8 of the connecting element 5. It is thus possible to arrange the connecting element 5 in the device in such a way that the central region 6, i.e. the offset region of the connecting element 5, points away from the platform 1 in the folded-in position, so that higher objects can be arranged on the platform than in the case of a straight configuration of the connecting element 5.Furthermore, FIGS. 1 to 6 show that the connecting element 5 is connected to the pivot arms 3, 3', 4, 4' via receiving elements 9, 9', which, however, does not necessarily have to be the case. The free ends of the outer regions 7, 8 of the connecting element 5 are each inserted into a receiving element 9, 9' and fixed with a fixing means 10, 10', for example a screw. This construction has the advantage that the width of the device can be adapted to the width of the furniture 2 by the outer regions 7, 8 being inserted correspondingly deeply into the receiving elements 9, 9' and being fixed in this position via the fixing means 10, 10'.Furthermore, fastening elements 11, 11' are provided, by means of which the swivel arms 3, 3', 4, 4' are connected to the platform 1. The swivel arms 3, 3', 4, 4' are connected to the piece of furniture 2 via further fastening elements 12, 12'.FIGS. 7 to 9 show a connecting element 5 according to the invention in different representations. It can be clearly seen again that the middle region 6 is formed offset with respect to the outer regions 7, 8. The cross section of the connecting element 5 is square, other geometries also being conceivable.The connecting element 5 can have, for example, an overall length 13 of 250 mm to 700 mm, in particular of 300 mm to 500 mm. The length 14 of the central region 6 can be, for example, 150 mm to 300 mm. The outer regions 7, 8 can have a length 15, 15' of 50 mm to 150 mm, for example.Furthermore, the central region 6 can be offset from the outer regions 7, 8 by 10 mm to 60 mm, for example, which is represented by the length 16.It is expressly pointed out that the length details given above are merely an example and should not be understood as restrictive. In particular, it is also conceivable that the outer regions 7, 8 are not of equal length. It is essential that the connecting element 5 is sufficiently dimensioned to be able to be arranged in a piece of furniture 2, preferably in a kitchen cupboard.With regard to further advantageous embodiments of the teaching according to the invention, reference is made to the general part of the description and to the appended claims in order to avoid repetitions.Finally, it should be expressly pointed out that the above-described exemplary embodiments of the device according to the invention and of the connecting element according to the invention serve merely to explain the claimed teaching, but do not restrict it to the exemplary embodiments.List of reference characters1 Platform 2 furniture 3, 3' pivot arm 4, 4' pivot arm 5 connecting element 6 central region 7 outer region 8 outer region 9, 9' receiving element 10, 10' fixing means 11, 11' fastening element 12, 12' fastening element 13 total length 14 length (central region) 15, 15' length (outer region) 16 offset length
