EP2703577A2 - Substructure for construction elements or furniture - Google Patents

Abstract

The sub-structure has structural elements (1,2) which are connected with each other through connecting units (3a-3e). The connecting unit is moved between a retracted pre-position and an extended fixing position by applying a temporary magnetic field from outside adjustable adjusting elements (4,5). An independent claim is included for a method for connecting and disconnecting of structural elements of sub-structure for component of furniture.

Description

The invention relates to a substructure for components, furniture or parts thereof, with construction elements to be connected to one another via a plurality of connection units.

For various construction measures in the field of exterior or interior construction, substructures recommend, often these are even necessary. In most cases, the structural elements belonging to the substructures are first connected to each other before z. As panels, facade elements or other components can be installed. A plurality of connection units then ensures the connection between the corresponding structural elements, to which screws and other proven fasteners offer. In some applications, however, there are special requirements, such as walls, facade elements or cladding panels for interior design, such as shops. In these monitors, displays or other electronic devices are often integrated taking into account various projections and recesses, fixtures, subjects, etc. Transitions, connections of cladding panels with each other or in the area of floor and ceiling, angles, corners, joints, etc. must meet the highest standards, which in turn requires connecting means of the highest quality. Every single connection must be made safely and, if necessary, be released again. In addition, there is a requirement that such compounds must not be able to solve in the long term, such as vibrations or other dynamic loads.

Thus, the present invention has the object to provide a substructure for components, furniture or parts thereof, which is easy to install and in which the connection units provide a secure and durable connection between the structural elements.

This object is achieved in that the connecting units have at least one between a retracted pre-position and an extended fixing position by applying a temporary magnetic field from the outside adjustable adjusting member.

Thus, such a substructure is characterized by a plurality of particularly reliably installed connection units. In contrast to previously known solutions, the construction elements forming the substructure can first be connected to the actual components, furniture or parts of these. Ie. First, the respective construction element z. B. attached to a facade or interior finishing element, then the respective structural elements are aligned with each other, only then come the connecting means are used. This is done in a particularly advantageous manner, namely by at least one adjusting member per connection unit, which is adjustable from the outside between a first retracted pre-position and then extended fixing position by applying a temporary magnetic field. Theoretically from outside the entire construction, the adjusting elements can be actuated by the targeted use of magnetism. With the response of the magnet thus an adjustment of the adjusting element and thus a closing or opening of the connecting means is accompanied.

In the context of the present invention, particular consideration is given to construction elements extending over a large area or extending over several meters. For this purpose, it is advisable that a first type of construction element has a housing rail for receiving the connection units. As an integral part of this construction serves to each other connecting components, etc., a housing rail, in which a plurality of connecting units are arranged as possible at a constant distance and aligned parallel to each other. Thus, the invention provides both tailor-made solutions according to predetermined dimensions and rail solutions that can be tailored only on site according to the particular need, the arrangement and orientation of the connection units can be adjusted to this.

Appropriately, it is provided that the housing rail has a web profile, in particular a substantially U-shaped web profile, which then can literally serve as a kind of (partial) housing for receiving the various connecting means.

This first construction element is supplemented by a profile which closes the open flank of the housing rail designed as a U-shaped web profile. The fact that the substructure has a cover profile corresponding to the web profile of the housing rail is thus understood to mean that after the cover profile has been fixed to the web profile, for example by inserting the cover profile into the web profile, a housing completely accommodating the various connecting means is realized any number of connection units can be accommodated in ultimately arbitrary arrangement. On the cover profile designed as a housing rail first construction element is also fixed to the corresponding facade or interior fitting, etc., including the cover profile should have holes at regular intervals.

For the arrangement of the connecting means in the housing is thought that the housing rail is equipped with paired bearing blocks for the connection units. The connection units are each inserted in such a pair of bearing blocks.

For the actual connection of the respective components, furniture or parts of these, it comes, as already mentioned, by connecting the two types of construction element. In this sense, the proposal is to be understood, according to which serves as a second type of construction element, a fixing rail, which is formed connectable via the connection units with the housing rail. After insertion of the first, formed from the housing rail and cover profile construction element in the second, designed as a fixing rail construction element, the connecting means can be adjusted from the retracted forward in the extended fixing position. The adjusting members of the adjusting elements enter into openings in the side wall of the housing rail.

As regards the actual fixing of the construction elements, it is provided that at least one magnet arranged in the housing rail serves for extending and retracting the adjustment member, which position can be adjusted from outside the construction elements between two positions corresponding to the preposition and the fixing position of the adjustment member. Housing rail and cover profile on the one hand and fixing on the other hand are assigned to the first or the component to be connected. In the first construction element formed from the housing rail and cover profile are located next to the adjusting members in the connection units and serving as a drive for the adjusting magnet. These can each be adjusted from outside the construction elements between two positions, which are tuned to the pre- and fixing position of the adjusting member. With the response of the magnet thus an adjustment of the adjusting element and thus a closing or opening of the connecting means is accompanied.

A significant advantage of the invention is the simplicity and the associated Störungsunanfälligkeit the system with respect to the adjustment of the adjustment between pre- or parking and fixing position for closing and opening of the adjustment, even permanently. In this sense, it is provided that the magnet is designed as a two-pole magnet for generating a temporary static magnetic field. The magnet is divided in half into North and South Pole. Ie. for closing and opening the connecting means is in contrast to previously known from the prior art solutions ( EP 1 056 953 or DE 10 2009 049 967 ) no rotating magnetic field needed, but only a temporary static. Thus, a comparatively simple magnetic mechanism suffices to be able to adjust the adjusting member between the two positions required here only from outside the substructure.

In this case, a variant of the invention provides that the magnet is rotatably mounted on a shaft, d. H. When approaching the magnetic pole of the magnet is set in rotation, which ultimately merges into a reciprocating the adjusting member. The magnet, which preferably has a cylindrical geometry, can therefore guide back and forth between two positions and drives the adjusting member via the intermediate shaft on which the magnet is positively positioned. On the one hand, this ensures the transmission of the torque from the magnet via the shaft to the adjusting member, on the other hand remains due to the positive connection between at least a portion of the shaft and the magnet any slippage, even in the stress due to vibrations excluded.

Because the adjusting member moves in a straight line between its positions, but the magnet is driven by rotation, it is recommended that a tooth connection is used to transfer the rotation of the magnet into a translational movement of the adjusting member. The already described shaft passes on the torque exerted on the magnet, where it transfers to the tooth connection. For this purpose, a toothed wheel is seated on the shaft, the rotation of which is transmitted to a toothed rack associated with the adjusting element.

A central aspect of the invention is the interaction of the magnet with its temporarily static bipolar magnetic field and the adjusting member. In this context, it is provided that the tooth connection is tuned so that an at least approximately half turn of the Magnets corresponds to the process of the adjusting between pre- or parking and fixing position or rotation in the other direction between the fixing and pre-position. The tooth connection consists of the gear already described on the shaft and a corresponding, a rack having adjustment member side link. The tooth connection is thus arranged and / or formed so that the rotation of the magnet to, for example, about 180 ° when approaching the magnetic pole, a method of adjusting in the adjustment between its pre-and fixing position.

With regard to the design of the adjusting member, it is proposed that the adjusting member has on its outside a clamping bolt and / or on its inside a guide slot. The inside guide slot thus serves to reciprocate the adjustment. On its outer side, the adjusting member has a clamping bolt, which is movable between the pre- or parking position within the housing rail and the fixing position in which the adjusting members are retracted into the fixing rail.

Because the forces or moments in both directions must be able to be exerted by the magnet on the adjusting member, it is expedient if the guide slot consists of four arranged in a rectangle flanks, of which at least one flank has a rack or is designed as such and although the upper and / or the lower edge.

For the purpose of anchoring the adjusting members in the fixing rail, the connecting unit should be equipped with at least two adjusting members. Specifically, a connection unit comprises at least two adjustable in the opposite direction adjusting members. These process when closing the connection to the outside and when opening the connection to the inside. Each of these adjusting members is in turn assigned a separate magnet in the embodiment with two adjusting members. So if a magnetic pole is brought from outside to the construction, both magnets are around each round 180 ° rotated so that the two adjusting members can extend or retract.

A further advantageous embodiment of the invention provides that a connecting unit comprises four adjusting members, wherein adjacent adjusting members are adjustable in the opposite direction. It is a kind of duplication of the adjustment, which ensures better management of the adjustment and thus a more reliable closing and opening mechanism.

A further preferred embodiment of the invention provides that the substructure is equipped with at least one inhibiting device for capturing the magnetic field of the magnets. By its properties, the inhibiting device is able to catch the magnetic field of the magnets, keeping them in their position and prevents the connecting means unintentionally opening due to external influences, such as vibrations or vibrations.

The invention also relates to a method for connecting and disconnecting the structural elements of a substructure for structural elements, furniture or parts thereof, wherein the structural elements are connected to each other via a plurality of connecting units and wherein the connecting units at least one adjustable between a retracted pre-position and an extended fixing position adjustment exhibit.

This method is characterized by the fact that the adjusting member is driven by at least one magnet which is displaceable outside of the construction elements between two positions corresponding to the pre-position and the fixing position of the adjusting member.

The invention is characterized in particular by the fact that a completely new substructure for components, furniture or parts of these is created. The actual components, furniture or parts of these are each initially equipped with construction elements. These are then connected to each other, which ensures considerable manufacturing advantages and a more accurate and permanently secure connection and thus substructure. To distinguish two types of construction elements, first a first, rail or panel-like constructed construction element that receives in the manner of a housing a plurality of connection units, which in turn are equipped with adjusting members which are adjustable between a pre or parking position and a fixing position , A second type of construction element is designed as a fixing rail, enter in the lateral openings, the adjusting members of the adjusting elements. This is done by applying a temporary magnetic field from the outside, to which only a temporary static magnetic field has to be generated in order to set two magnets as part of the connection units in rotation. These magnets set a shaft and finally via a tooth connection, the adjusting elements in motion, the outside clamping bolts then fix in the opposite fixing rail and thus create a durable reliable and highest static and dynamic stresses resistant connection. Of central importance is the coordinated interaction of the two magnets with the adjusting elements. If the magnets are set in rotation, this torque is transmitted via the shaft and the tooth connection to the adjusting members. In this case, these components are synchronized so that a predetermined degree of rotation of the magnet, preferably a rotation of almost 180 ° corresponds to the process of the two adjusting members between their retracted pre- and extended fixing position.

The invention thus makes a significant contribution to the standardization of such technical solutions in which outer temporary magnetic fields are applied for the purpose of fixing adjusters. In future, rails or panels can be used, which are already prepared by the arrangement of adjusting elements. The construction elements in the form of housing, Lid and fixing rails can either be delivered in the required dimensions or cut to size on site.

FIG. 1 The first consists of the housing rail 31 and the cover profile 33, the latter from the Fixierschiene 36. By connecting or assembling the two construction elements 1, 2 takes place at the same time necessarily connecting the two Components to which they are assigned. In the housing rail 31 connecting units are provided here by way of example with the reference numerals 3a - e used, including the housing rail 31 paired bearing blocks 34a - e or 35a - e has. After insertion of the connecting units designed as a substantially U-shaped web profile 32 housing rail 31 is closed by inserting the flat cover profile 33. Subsequently, the fixing of the first construction element 1, more precisely the cover profile 33 via the example by the reference numerals 52, 53 designated holes on the first component or furniture, not shown here. Meanwhile, designed as a fixing rail 36 second structural element 2 by means of exemplified by the reference numerals 54, 55 holes fixed to the other component or furniture. The connection is finally made by inserting the construction element 1 (housing rail 31 and cover profile 33) into the second construction element 2 (fixing rail 36). Here, the temporary magnetic field comes into play, which causes the adjusting members 4 and 5 shown here for illustrative purposes only in the connection unit provided with the reference numeral 3 retract into the openings 41, 42 in the side wall 45, 46 in the housing rail 31, so that it comes to a permanent fixation.

The representation according to FIG. 2 refers to such designed as a web profile 32 housing rail 31 with the paragraphs 60, 61, which in turn correspond with internals in the fixing profile. Shown is in FIG. 2 also a bearing block 34 for receiving the connection unit, not shown here.

A fixing rail 36 shows FIG. 3 , This consists of the two bottom webs 39 and 40 and the two side bars 62 and 63. By the reference numerals 37 and 38 projection-like supports 37, 38 are designated, which correspond to the paragraphs 60, 61 in the housing rail 31, ie the paragraphs 60, 61st on the housing rail 31 are in the installed state on the supports 37, 38

Finally, in FIG. 4 To recognize two construction elements 1, 2 in the installed state. The connecting unit 3 is inserted into the web profile 32 of the housing rail 31, the shaft 10 is mounted in the bearing block 34. As upper end of the first construction element 1 or for the web profile 32, the flat cover profile 33 is used. With the paragraphs 60, 61 is the web profile 32 on the supports 37, 38 of the fixing rail 36. The adjusting members 4, 5 can now be extended by addressing the magnet 7 in the fixing position, ie outwardly into the fixing rail 36 in the direction of arrows 29, 30.

To clarify this mechanism is also used FIG. 5 , An exploded view of the components gear 15, shaft 10, adjusting member 4, 5, 8, 9 and magnet 6, 7. The actual connection of the construction elements 1, 2 it comes by extending the adjusting members 4, 5, 8, 9 and a kind of clamping action the clamping bolt 21 a, 21 b, 22 a, 22 b on the outer sides 17 a, 17 b, 18 a, 18 b of the adjusting members 4, 5, 8, 9. So that the adjusting members 4, 5, 8, 9 extend or retract, are the Magnets 6, 7 by generating a temporary static magnetic field in rotation by almost 180 ° to put, which is particularly well possible because the magnets 6, 7 "only" north and south pole, so can not do otherwise than to rotate accordingly , The rotation of the magnets 6, 7 is then transmitted to the shaft 10 and from there via the gear 11 formed as a toothed connection 11 on the adjusting members 4, 5. The shaft 10 has quadrangular sections 58, 59, which in turn correspond to the bores 56, 57 in the magnets 6, 7. The transmission of the torque from the magnets 6, 7 via the shaft 10 and the tooth connection 11 to the adjusting members 4, 5, 8, 9 is thus realized. The rotation of the shaft 10 is finally converted into a translational movement of the adjusting 4, 5, 8, 9. Responsible for this is the guide slot 23, 24 with the flanks 25 - 28 and 48 - 51 on the inside 19a, 19b, 20a, 20b of the adjusting members 4, 5, 8, 9. Of particular importance are the trained as racks 12, 13 or such having flanks 27 and 49, namely a lower flank 27 and an upper flank 49, respectively, in order to enable the process of the two adjusting members 4, 5 towards and away from one another.

In plan view shows FIG. 6 A connection unit with the four adjusting members 4, 5, 8 and 9. It can be clearly seen that adjacent adjusting members, about 4 and 8, 8 and 5 or 5 and 9 different directions or against each other in the direction of the longitudinal axis 44 and retractable , The compactness of this double solution for the adjusting members 4, 5, 8, 9 is obvious.

In perspective view shows FIG. 7 a connecting unit 3, wherein the guide slot 23 is particularly well recognizable. Such have all four adjusting members 4, 5, 8, 9. The central component is the flank 49 with the rack 13 for transferring the force exerted on the shaft 10 via the magnets 6, 7 torque on the adjusting members 4, 5, 8, 9 in interaction with the tooth mechanism.
