Abstract
Description
[0001] The present invention relates to cable chains, cable guides with cable chains, and table legs or table frames with such cable guides. In particular, the invention relates to cable chains that have different sections with a different number of degrees of freedom. Furthermore, the invention relates to adapters for such cable chains and tables (e.g., desks) with corresponding table legs and / or table frames.
[0002] Cable chains within the meaning of the present invention, which can also be referred to as cable or energy guiding chains, are systems for guiding energy and / or data lines, formed by several articulated chain links. Adjacent chain links are therefore spatially deflectable relative to one another, usually in several degrees of freedom. Depending on the design of the articulated connection, adjacent chain links can be displaceable relative to one another to allow compressibility of the cable chain, can be rotatable relative to one another about the longitudinal axis of the cable chain, and / or can be rotatable or pivotable relative to one another about one or more axes, which are usually perpendicular to the longitudinal axis of the cable chain.
[0003] For this purpose, the chain links of the cable chain are typically each equipped with one or more connecting elements, which may have a plug attachment or a connecting eyelet for connecting to an adjacent link. The known chain links also have an outer part or sheathing element. This forms a boundary that accommodates the cables routed along the cable chain. To accommodate the cables routed along the cable chain in the sheathing element, the sheathing element can have one or more openings through which the cables can be inserted into the sheathing element. Such cable chains are known, for example, from DE 10 2006 030 086 A1 of the applicant.
[0004] However, the existing cable chains exhibited consistent flexibility along their length. This can be undesirable in certain installation situations, such as when mounted on table legs.
[0005] Height-adjustable desks with cable guides are known, for example, from WO 2013 / 037 072 A1, US 7 640 866 B1, JP 4 846 347 B2, and DE 203 13 535 U1. These publications describe various options for routing cables, e.g., in the form of a cable harness in a cable chain, with the cables extending between different devices or from an outlet to the underside of the tabletop.
[0006] The invention is therefore based on the object of providing cable chains that are better adapted to the respective installation situation. A further object is to provide table legs and tables with improved cable routing. Furthermore, the aim is to provide an adapter for improving existing cable chains.
[0007] The object is achieved by the features of claim 1. Preferred embodiments are the subject of the subclaims.
[0008] Accordingly, the present invention relates to a table leg for a height-adjustable office table, comprising: a fixed table leg part and an extendable table leg part; at least one continuous cable guide with a continuous cable chain for guiding cables, which is formed by a plurality of chain links connected to one another via articulated connections; wherein the chain links of the cable chain have identical casing bodies or the same external dimensions over the entire cable chain length and the articulated connections are formed by one or more connecting bodies of a chain link and one or more receptacles for the connecting bodies of an adjacent chain link, wherein the cable chain has a first section extending along the immovable part and a second section extending in the region of the extendable part;wherein the chain links of the cable chain (70) are rigidly connected along the first section and adjacent chain links along the second section are pivotable relative to one another about a first axis of rotation which is perpendicular to the longitudinal axis of the cable chain, wherein the different mobility of the cable chain along the sections and is achieved by the design of the connecting bodies of the chain links and / or their receptacles;
[0009] The cable chain preferably has two, three, four, or more sections with different degrees of mobility, i.e., in particular, sections in which adjacent chain links can be moved relative to one another by a different number of degrees of freedom. Thus, adjacent links of the cable chain along a first section can be moved relative to one another by a first number of degrees of freedom, while adjacent links along a second section of the cable chain can preferably be moved relative to one another by a second number of degrees of freedom. A section can preferably have at least two, four, six, or ten directly consecutive chain links.Cable chains or cable guides according to the invention can have any combination or all of the first, second, third and fourth sections described below, in particular the described first and second section, the described first and third section, the described first and fourth section, the described second and third section, the described second and third section, the described third and fourth section, the described first, second and third section, the described first, second and fourth section, the described first, third and fourth section, the described second, third and fourth section or the described first, second, third and fourth section.
[0010] The chain links can, in particular, be designed such that they have at least one, exactly one, or at least two more degrees of freedom along the second section than along the first section. Furthermore, a third section can be provided, along which the cable chain can preferably have at least one, at least two, or three more degrees of freedom than along the second section. The cable chain can therefore have at least two more degrees of freedom along the third section than along the first section.
[0011] In the context of the present invention, a degree of freedom is preferably understood to mean the movement possibilities of two directly adjacent chain links, which can result in particular from the design of their connection. The available degrees of freedom can be determined significantly by the design of the connecting elements of the chain links. However, additional elements can be provided that restrict the mobility accordingly.
[0012] According to the invention, one or more degrees of freedom can also be partially restricted in certain sections. For example, along the first section, rotation may only be possible in one direction, whereas along the second section, rotation in both directions (e.g., clockwise and counterclockwise) is permitted. Furthermore, according to the invention, for example, along the first section, rotation in one direction may only be possible up to a certain maximum angle of rotation, whereas along the second section, rotation in this direction is permitted up to a larger maximum angle of rotation.
[0013] As exemplified in Fig. 1A and Fig. 1B, the chain links 71A, 71B can each have a connecting body 73 in the form of a plug attachment, which can have a thickened end portion 74. The connecting body 73 can be surrounded by an outer part or sheath body 75, into which the cables are received. Chain links can also have connecting bodies in the form of connecting eyes. In this case, an eyelet can be provided on an arm that extends away from the sheath body 75. Alternatively, the eyelet can be formed on or in the sheath body. In this case, the chain links have pins that engage in the eyes.
[0014] Depending on the design of the connecting section 73 (in the example shown, in particular depending on the design of the plug attachment, the end thickening 74, and the respective receptacle for this end thickening), the chain links can have different degrees of freedom. These include, in particular, the ability to pivot about a first axis D1, which is perpendicular to the longitudinal direction L of the cable chain; the ability to pivot about a second axis D2, which is perpendicular to the longitudinal direction L of the cable chain and to the first axis D1; the ability to rotate about the longitudinal axis L; and the ability to displace V in the longitudinal direction L, each of which can be defined as a degree of freedom. For example, the end thickenings 74 can be designed as a sphere or cylinder.
[0015] As an aid to defining the degrees of freedom, an imaginary Cartesian coordinate system can be projected onto the connection point of the respective chain links. This system is shifted along the longitudinal axis L of the cable chain and remains the same for each chain link, regardless of its orientation in space. The first coordinate axis X is then preferably congruent with the longitudinal axis L of the cable chain (or at least with the longitudinal axis of the respective chain link), while the second and third coordinate axes Y and Z extend perpendicular to the longitudinal axis of the cable chain (see Fig. 1A). The rotation axis D1 then preferably corresponds to the Z axis, and the rotation axis D2 to the Y axis. The directions of rotation can be positive or negative in the mathematical sense ("right-hand rule").
[0016] The chain links are rigidly connected to each other along the first section.
[0017] The second section preferably adjoins the first section directly. Along this section, the cable chain can be designed so that the chain is not compressible, which can also be achieved in this case by designing the connection between the chain links and / or by using appropriate locking devices. In particular, the connecting sections and / or their receptacles can be designed so that pushing adjacent chain links together is impossible.
[0018] Adjacent chain links can be pivoted and / or rotated relative to one another along the second section, preferably about a first axis of rotation, wherein the first axis of rotation is preferably perpendicular to the longitudinal direction of the cable chain and / or to the longitudinal axis of the respective chain links. Preferably, no pivoting about further axes that are perpendicular to the longitudinal axis of the cable chain and / or the respective chain links is possible along the second section. Adjacent chain links can therefore preferably only be pivoted relative to one another along this section about the first axis of rotation. The formation of a corresponding pivotability of the chain links can be achieved in particular by the design of the connecting sections and / or their receptacles along the second section, but also by the use of corresponding locking elements.The second section can therefore be designed so that it is movable in a first plane, preferably only in this plane.
[0019] The second section can therefore, under certain circumstances, be designed to have the freedom of movement and / or degrees of freedom of a tank or track and / or roll accordingly. The second section can have the same external shape, geometry, and / or dimensions as the first section.
[0020] The third section can directly adjoin the first section. The cable chain can be configured along this section, for example, to allow compression of the cable chain along the section. This can be achieved, in particular, by appropriately designing the connecting sections and their receptacles, which can be configured to allow adjacent chain links of the third section to be pushed together.
[0021] Alternatively or additionally, the connecting sections along the third section can be designed such that adjacent chain links can be pivoted and / or rotated relative to one another about a first axis of rotation, which is preferably perpendicular to the longitudinal axis of the cable chain and / or perpendicular to the longitudinal axes of the respective chain links.
[0022] Preferably, adjacent chain links along the third section are also pivotable and / or rotatable relative to one another about a second axis of rotation. This second axis of rotation is preferably also perpendicular to the longitudinal direction of the cable chain and / or to the longitudinal directions of the chain links. The second axis of rotation can also be provided perpendicular to the first axis of rotation of the second section. The third section can therefore be designed such that it is movable in a first plane and a second plane.
[0023] Alternatively or additionally, the cable chain can be designed along the third section such that adjacent chain links along this section can be rotated relative to one another about the longitudinal axis of the cable chain and / or about the longitudinal axes of the respective chain links (e.g., can be rotated helically).
[0024] The cable chain according to the invention can also have a fourth section. The fourth section can be directly connected to the second section.
[0025] Along the fourth section, the cable chain can be designed such that it is not compressible along this section, i.e., adjacent chain links cannot be displaced relative to one another, particularly in the longitudinal direction of the cable chain. Alternatively, the section can also be designed such that it is compressible. Both alternatives can be realized, for example, by the design of the connecting sections of the chain links and / or by the use of appropriate locking devices.
[0026] The cable chain can also be configured along the fourth section such that adjacent chain links can be pivoted about a first axis of rotation, which is perpendicular to the longitudinal axis of the cable chain and / or perpendicular to the longitudinal axis of the respective chain links. In this case, too, corresponding mobility along the section can be achieved by the design of the connecting sections of the chain links and / or the corresponding receptacles. The fourth section can be provided such that the first axis of rotation of the chain links of the fourth section is perpendicular to the first axis of rotation of the chain links of the second section (to the axis of rotation of all or at least some of the links of the second section).
[0027] Adjacent chain links of the fourth section can also be pivotable relative to one another about a second axis of rotation. This second axis of rotation is preferably also perpendicular to the longitudinal axis of the cable chain and / or to the longitudinal axes of the respective chain links. Furthermore, the second axis of rotation can be perpendicular to the first axis of rotation of the fourth section. Alternatively, the cable chain along the fourth section can be designed such that adjacent chain links can only be pivoted relative to one another about the first axis of rotation.
[0028] The cable chain can further be configured along the fourth section such that adjacent chain links are rotatable relative to one another about the longitudinal axis of the cable chain and / or about the longitudinal axes of the respective chain links, so that, for example, a spiral connection of the fourth section (e.g., in the form of a helix) is possible. Alternatively, the fourth section can be configured such that the chain links are not rotatable about the longitudinal axis of the cable chain and / or about the longitudinal axes of the respective chain links.
[0029] If reference is made above or below to a pivoting, rotation, and / or twisting of adjacent chain links of the first, second, third, and / or fourth section about a first or second axis of rotation, this particularly refers to a pivoting through an angle of at least 10°, at least 20°, at least 30°, at least 40°, or at least 50°. In the pivoted state, this angle is preferably formed between the longitudinal axes of the two adjacent chain links. The pivoted state is to be distinguished from a neutral state in which the cable chain is straight and the longitudinal axes of the adjacent chain links are congruent.
[0030] Depending on the type of cable chain, the design of one or more connecting elements of the chain links, and / or the locking devices used, adjacent chain links can be pivoted by a maximum of 60°, a maximum of 40°, a maximum of 30°, or a maximum of 20°. Different pivoting angles around the same axis of rotation can be possible in opposite directions of rotation. In particular, a pivoting angle of at least 20°, at least 30°, at least 40°, at least 50°, or at least 60° can be possible in one of the directions of rotation, while pivoting in the opposite direction of rotation around the same axis of rotation is limited to a maximum angle of 2°, 5°, or 10°, or is prevented entirely. Therefore, greater pivoting angles can be possible in the positive direction of rotation than in the negative direction of rotation (or vice versa).
[0031] The pivotability of adjacent chain links of the first, second, third and / or fourth section about the first and / or second axis of rotation can also be restricted such that a bending of the guided cables by a radius of curvature of less than 8 cm, less than 5 cm, less than 3 cm, less than 1 cm or less than 0.5 cm is blocked.
[0032] The cable guide according to the invention is formed by a continuous cable chain. The sheath bodies of the chain links in the first section, the second section, the third section, and / or the fourth section are preferably identical or have the same external dimensions (all permutations of the sections are considered). This avoids protruding parts and achieves a consistent storage space for the cables, which hinders the user as little as possible and minimizes the risk of injury. Furthermore, this results in a homogeneous appearance of the entire cable guide, which is appreciated by many users. The sheath bodies of the chain links in the first, second, third, and / or fourth section can be rectangular, square, round, or oval.
[0033] The fourth section can run at least partially or largely beneath the table top or in a recess (e.g., in a cable duct or in the space between a double-walled table top). For this purpose, the sheathing bodies of the chain links of this fourth section can optionally have different dimensions than the sheathing bodies of the chain links of the first, second, and / or third section. It is particularly preferred to use sheathing bodies with a smaller cross-section and / or smaller external dimensions than along the first, second, and / or third section in order to make the cable duct as flat as possible. In particular, the sheathing bodies of the chain links of the fourth section can be narrower. The sheathing bodies of the chain links of the fourth section can therefore be designed so that the overall height of a cable duct in which they are arranged is as low as possible.This means that as little space as possible is taken up under the table top, which allows greater freedom of movement for the user's legs.
[0034] The fourth section can also be redirected and / or redirected within the catchment area. It can essentially form a U-shape.
[0035] According to a further aspect, the invention relates to a table leg or table frame with a cable chain or cable guide according to the invention. The cable chain preferably runs at least along the first section and / or along a part of the second section of the table leg. The table leg according to the invention can, in particular, be height-adjustable. For this purpose, it can have a first part that is immovable and / or fixed, and a second part that is movable and / or extendable. The table leg can be designed as a telescopic leg, wherein the outer part of the telescopic leg can form the lower, fixed part and the inner part of the telescopic leg can form the extendable, upper part. Alternatively, the inner part of the telescopic leg can form the lower, fixed part of the table leg and the outer part of the telescopic leg can form the upper, movable part of the table leg.
[0036] The first section can extend, in particular, along the stationary part. The second section can run at least partially or largely in the area of the extendable part of the table leg, in particular when the table is raised. The first coordinate axis X of Fig. 1A can in this case extend along the first section and / or the part of the second section that runs along the table leg, in the vertical direction and / or in the longitudinal direction of the table leg. The second and / or third coordinate axes Y can therefore be horizontal, with the second coordinate axis preferably pointing from the longitudinal axis of the cable chain toward the table leg.
[0037] In the region of the first section, the cable chain preferably cannot bulge from the table leg in the (positive and / or negative) direction of the second coordinate axis Y. For this purpose, the cable chain is designed rigidly along this section. The cable chain can preferably be attached to the table leg along the first section. For this purpose, one, two, or more attachment devices can be used, such as those described in the parallel German patent application of the present applicant entitled "Device for Attaching a Cable Guide Chain," which has the same filing date. The content of this application is hereby incorporated by reference in its entirety.
[0038] The cable chain can thus be attached to the table leg at one, two or more points along the first section, preferably in such a way that it can be attached to and / or detached from the table leg without tools and / or without leaving any marks.
[0039] Along the second section, the cable chain is preferably only attached or fixed to the table leg at one point or not at all. Adjacent chain links are preferably pivotable relative to one another about a first axis of rotation (see above). When the cable chain is attached to the table leg, this first axis of rotation is preferably horizontal and / or congruent with the third coordinate axis Z. As a result, the cable chain can be designed such that it can roll off the table leg along the second section in the negative direction of the second coordinate axis Y and / or bend away from the table leg in this direction. The cable chain can also be designed along the second section such that it can bend towards the table leg. Alternatively, such bending towards the table leg along the second section can also be prevented or reduced to a minimum (e.g., to a maximum twist angle of adjacent chain links of 2°, 5°, or 10°).
[0040] By preventing the cable chain from being rotatable along the second section about further axes that are perpendicular to the longitudinal direction of the cable chain and / or to the first axis of rotation, pivoting of adjacent chain links about the second coordinate axis Y (in the positive and / or negative direction of rotation) can be avoided. This prevents the cable chain from being deformed along the second section in the direction of the third coordinate axis Z (in the positive and / or negative coordinate direction). This prevents, for example, buckling of the cable chain in the direction of the third coordinate axis Z (positive and / or negative coordinate direction).
[0041] The third section of the cable chain can be provided and / or designed such that cables can be guided along the floor to the table leg, in particular from a floor outlet. The third section is particularly suitable for guiding the cables from the floor outlet to the first section and can therefore connect directly to the first section (preferably on the side of the first section opposite the second section). Some or a large part of the chain links of the third section can therefore extend along the floor. However, it should be noted that the third section can also extend partially along the table leg and / or along the transition area between the floor and the table leg.
[0042] Along the third section, the cable chain is preferably configured such that the first axis of rotation of the chain links of the third section is substantially parallel to the second coordinate axis Y. For the chain links of this section that extend along the ground, this may mean that the first axis of rotation is vertical and / or perpendicular to the ground. In this case, the second axis of rotation may be substantially parallel to the third coordinate axis Z and, for the chain links that extend along the ground, substantially horizontal.
[0043] The fourth section can be provided and / or configured to guide the cables along a tabletop and / or in a cable duct, which can extend, for example, beneath the tabletop. At least some or all of the chain links of the fourth section can run along or beneath the tabletop and / or in the cable duct.
[0044] According to a first embodiment of the table leg or table frame according to the invention, the cable chain is designed such that it sags along the second section when the table leg is lowered. This provides sufficient length for raising the table leg. The cable chain can sag in the shape of a U or in the shape of a horizontal S, so that the second section of the cable chain can assume a substantially coiled shape. The cable chain can be at least partially attached to the table leg. Alternatively or additionally, one end of the cable chain can be attached to the floor (e.g., via a base and / or base plate) or to the table frame, and the other end to the table top and / or a cable duct. If a base and / or base plate is used, a mounting rod can be provided on it, via which the chain links of the first section are rigidly connected to one another.The base and / or the base plate (in particular the mounting rod) can be arranged such that the cable chain in the first section extends substantially vertically upwards from the base and / or the base plate, wherein the angle formed by the longitudinal axis of the cable chain in the first section with the floor is preferably between 80° and 100° or between 85° and 95°, more preferably 90°. The first section can therefore also be referred to as the "vertical" section.
[0045] The unrolled length and / or the height of the first (preferably rigid) section can be at least 2%, at least 5%, at least 10%, at least 20% or at least 30% of the unrolled length of the first and second sections combined (i.e., the total unrolled chain length if no further sections are provided). The distance between the chain links of the first section can optionally be smaller than the distance between the chain links of the second section, preferably by at least 20%, at least 50% or at least 60% smaller. For example, the distance a can be at least 2 mm, at least 5 mm, at least 10 mm or at least 20 mm smaller than the distance b. Optionally, the chain links in the first section can also be adjacent to one another (distance equal to zero), so that the first section can be referred to as a "closed" cable chain.
[0046] The cable chain, in particular its first and second sections, are preferably dimensioned and / or matched to the table height so that the cable chain (in particular the sagging part of the cable chain) does not touch the floor even when the table leg or table frame is fully lowered. The cable chain therefore preferably "floats" above the floor. The distance between the lowest point of the chain links in the sagging area and the floor is preferably at least 2 cm, at least 5 cm or at least 10 cm. However, it can also be at least 20 cm, at least 30 cm or at least 40 cm. Depending on the design of the cable chain, these dimensions can alternatively apply to a minimum distance between the center line of the cable chain in the sagging area and the floor when the table leg or table frame is lowered.
[0047] When the table leg or table frame is lowered, the distance between the lowest point of the chain links in the sagging area is preferably less than the length of the first section and / or less than the height at which this first section transitions into the second section. When the table leg or table frame is in the middle position, the distance between the lowest point of the chain links in the sagging area and the floor preferably corresponds approximately to the length of the first section and / or the height at which the first section transitions into the second section. When the table leg or table frame is fully extended, the distance between the lowest point of the chain links in the sagging area and the floor is preferably greater than the length of the first section and / or greater than the height at which the first section transitions into the second section.Depending on the design of the cable chain, these ratios may alternatively apply to the shortest distance between the center line of the cable chain in the sagging area and the ground.
[0048] According to a second embodiment of the table leg according to the invention, the second section of the cable chain can run along the extendable part, preferably almost to the end of this extendable part. The second section can preferably be provided substantially straight along the extendable part of the table leg and / or not sag noticeably. This makes it possible to design the second section of the cable chain so that, when the table leg is lowered, it is pushed into a retraction space (e.g., into a cable duct or into the space between a double-walled table top, which can each run horizontally beneath the table top).
[0049] In the second embodiment, a retraction device can be used alternatively or additionally. This exerts a tensile force on the section of the cable chain when the table leg is lowered, thus actively retracting it into the cable duct. In this case, a deflection device can be used to insert the second section of the cable chain into the cable duct during the lowering process. The retraction device can, for example, comprise spring elements.
[0050] Within the scope of the second embodiment, a deflection device can also be used to successively deflect the chain links of the section from a vertical orientation to a horizontal orientation as the table leg is lowered. This deflection device can have an inner bracket (on the inside of the curved section) and / or an outer bracket (on the outside of the curved section). Furthermore, the deflection device can be provided with lateral guides. The outer bracket is particularly advantageous in embodiments in which the cable chain is subjected to pressure as the table leg is lowered and / or is thereby passively pushed into the intake space.
[0051] Also described is an adapter for connecting two cable chains and / or for connecting two sections of a cable chain. The adapter has a first connecting section, which is designed to fasten a first cable chain or a first cable chain section to the adapter, and a second connecting section, which is designed to fasten a second cable chain or a second cable chain section to the adapter. The first and second connecting sections of the adapter can be designed such that a different type of cable chain can be fastened to the first connecting section than to the second connecting section. In this way, the properties of different cable chains can be combined along a continuous cable guide. Optionally, the first and / or the second connecting section can be designed such that different types of cable chains can be fastened to them.The adapter can be designed as an integral component. In particular, it can arrange the first and second cable chains relative to one another in such a way that a substantially closed transition between the cable chains results. The cables are preferably exposed in the adapter over a length of less than six times, four times, twice, or one times the gap between two chain links of the first or second cable chain.
[0052] Additionally or alternatively, the connecting sections of the adapter can be provided such that the second cable chain (or the second cable chain section) is arranged offset or rotated relative to the first cable chain (or the first cable chain section) about the longitudinal axis of the first and / or the second cable chain (and / or about the longitudinal axis of the last link of the respective cable chain that is attached to the adapter) (e.g., offset by 60° to 120°, 80° to 100°, or approximately 90°). For example, if the first cable chain and the second cable chain have similar or comparable degrees of freedom (e.g., pivotability of adjacent chain links about only a first axis of rotation perpendicular to the longitudinal axis of the cable chain and / or the respective chain links), this can result in different spatial mobility along the first cable chain and the second cable chain.The rotational axis of the second cable chain is thus arranged so that it is rotated relative to the rotational axis of the first cable chain around the longitudinal axis of the cable guide. The second cable chain can have the lowest possible height so that it takes up little space under the table. This height preferably corresponds approximately to the narrowest height of the first cable chain. The first cable chain can preferably have a rectangular cross-section, and the second cable chain can preferably have a square cross-section. The maximum width or height of the second cable chain is preferably smaller than the maximum length or width of the first cable chain.
[0053] This adapter can be designed as a carriage or mounted on a carriage.
[0054] Also described is a cable guide with an adapter and a cable chain according to the invention. In this case, the adapter can be provided in particular between the previously described second section of the cable chain according to the invention and the previously described fourth section of the cable chain according to the invention. The previously described second section preferably forms the first cable chain and the previously described fourth section forms the second cable chain, which are fastened to the adapter. The cable guide according to the invention with adapter therefore preferably has at least these two sections, which can each have the previously described degrees of freedom and / or properties. Optionally, the first and / or third section of the previously described cable chain according to the invention can also be provided along the cable guide. These can also have the above-described degrees of freedom and / or properties.
[0055] Also described is a set comprising an adapter and two cable chains and / or cable chain sections attachable thereto, wherein the first cable chain and / or the first cable chain section can have the properties of the second section of the previously described cable chain. The second cable chain and / or the second cable chain section can have the properties of the fourth section of the previously described cable chain.
[0056] According to a further aspect, the invention relates to a table with a table leg according to the invention. This can, in particular, be a height-adjustable table.
[0057] The second section of the cable chain according to the invention can be fixed to the tabletop. The second section can be fixed to the tabletop, in particular, at the end opposite the first section of the cable chain. In this case, the cable chain can be provided on the table in such a way that it sags along the second section to provide sufficient length for raising the table. As previously mentioned, the second section can sag, in particular, in the shape of a U or a horizontal S.
[0058] The table or table frame according to the invention can have a cable duct, which preferably extends along the table top (in particular underneath it). In this case, the cable chain can be provided on the table such that the second section of the chain is at least partially received in the cable duct when the table is lowered. The fourth section of the cable chain can also run partially or completely within the cable duct. In this case, the limited mobility of the second section of the cable chain can ensure that the cable chain is only pushed into the cable duct in the desired direction when the table is lowered and does not bulge and / or bend in other directions along the table leg or in the cable duct.This can be achieved, for example, in that adjacent links of the second section of the cable chain can only be pivoted about a rotation axis that is perpendicular to the longitudinal axis of the cable chain and / or to the longitudinal axes of the respective chain links. This first rotation axis is preferably parallel to the third coordinate axis Z and / or horizontal. In addition, the pivotability about the first rotation axis is preferably only possible in one direction of rotation or is reduced to a minimum in the opposite direction of rotation (e.g. to a maximum angle of rotation of 2°, 5° or 10°). In particular, a greater rotatability of the higher chain link of the second section relative to the lower adjacent chain link in the negative direction of rotation about the third coordinate axis Z than in the positive direction of rotation about this coordinate axis Z is desirable.
[0059] The table can also have a retraction device (e.g., in the form of a spring mechanism) in the retraction space (e.g., in the cable duct) and / or under the tabletop to retract the second section of the cable chain into the retraction space (e.g., into the cable duct) when the table is lowered. This can include springs, which are preferably designed to be deflected when the second section is pulled out of the cable duct when the table is raised. The springs can, for example, be designed as spiral springs and / or helical springs.
[0060] An adapter can be provided under the table top and / or in the cable duct to connect the second and fourth sections of the cable chain.
[0061] Furthermore, a table frame and a table with such a table frame are described. The table frame preferably has at least one height-adjustable table leg and a cable chain for guiding cables, with a section of the cable chain extending along the table leg. Furthermore, at least one fastening device is preferably provided that fixes a first end of the section of the cable chain that extends along the table leg. The section of the cable chain is preferably guided vertically along the table leg.
[0062] The table frame or table preferably further comprises a retraction space for the cable chain and a retraction device that applies tensile load and tension to the section of the cable chain that extends along the table leg. A deflection device can also be provided that deflects the section of the cable chain and guides it into the retraction space.
[0063] The table leg of the table frame can have a fixed part and an extendable part. The fixed part can be formed by the outer part of a telescopic leg. Alternatively, the fixed part can be formed by the inner part of a telescopic leg. The table leg can thus correspond to the above description.
[0064] The cable chain of the table frame can be a cable chain according to the invention as described above. However, it can also be a cable chain that has uniform mobility along its entire length.
[0065] The section of the cable chain that extends along the table leg and / or is retracted into the retraction space can be designed correspondingly to the second section of the cable chain according to the invention. In particular, the section of the cable chain that extends along the table leg and / or is retracted into the retraction space is preferably designed such that adjacent links of the section can be pivoted relative to one another about at least one axis of rotation. The at least one axis of rotation preferably runs substantially horizontally. The cable chain can therefore be deformable along the section in a vertical plane.
[0066] The cable chain may further comprise one or more additional sections of varying mobility, such as an additional section corresponding to the first section of the cable chain according to the invention, an additional section corresponding to the third section of the cable chain according to the invention, and / or an additional section corresponding to the fourth section of the cable chain according to the invention. If a section is provided that corresponds to the third or fourth section of the cable chain according to the invention, it is preferably designed such that it is not subjected to tensile stress by the retraction device.
[0067] If the cable chain comprises a section that corresponds to the fourth section of the cable chain according to the invention, this section is preferably provided in the retraction space. The fourth section can be arranged in the shape of a helix and / or rotated about its longitudinal axis, for example in accordance with the previous description for the second embodiment of the table or table frame (see above). Alternatively or additionally, an adapter according to the invention can be provided between the section that extends along the table leg and / or is retracted into the retraction space and the fourth section (see above). This adapter can be designed as a carriage or mounted on a carriage.
[0068] The cable chain can rest against the table leg in the area of the fixed part or be spaced from the table leg by a maximum of 0.5 cm, a maximum of 1 cm, a maximum of 2 cm, or a maximum of 5 cm. Alternatively or additionally, the cable chain can be spaced from the table leg in the area of the extendable or inner part at a distance sufficient to allow the table leg to be lowered (i.e., preferably, the telescopic leg to be retracted). For this purpose, the cable chain can be spaced from the table leg by a minimum of 0.5 cm, a minimum of 1 cm, a minimum of 2 cm, a minimum of 3 cm, or a minimum of 5 cm in the area of the extendable or inner part.
[0069] The cable chain is preferably secured to the table frame via the fastening device, for example, to the table leg and / or the base of the table leg (e.g., to the crossbeams at the bottom of the table leg). Alternatively, the fastening device can secure the cable chain to the floor. The fastening device is preferably designed and / or configured to absorb the tensile force of the retraction device. A strain relief device can be provided for this purpose in the area of the fastening device. For example, the fastening device can have a strain relief device for the cable chain or be configured as such a strain relief device.
[0070] The table frame can comprise precisely one or more fastening devices. The one or more fastening devices can be provided on the fixed part. This applies in particular if the fixed part is provided below the extendable part. Alternatively, the extendable part can be provided below the fixed part. In this case, the one or more fastening devices are preferably provided at the base of the table leg and / or near the floor.
[0071] In general, the fastening device can be attached to the table leg using one or more fixing devices. These can include, for example, a clamp, a snap device, a screw, a magnet, a hook-and-loop fastener, and / or a fastening strap (e.g., a fastening strap with a buckle, buttons, and / or a hook-and-loop fastener). The fixing device can be formed on the fastening device (e.g., integrally with it) or on the table frame.
[0072] Alternatively or additionally, the fastening device can be glued to the table leg, to its base (e.g., to one of the crossbars at the bottom of the table leg), or to the floor area. Furthermore, the fastening device can be designed as a bracket attached under the table leg or one of the crossbars at the bottom of the table leg, for example, via a snap-in device. Furthermore, the table leg can stand on the fastening device to secure it.
[0073] The intake space of the table frame or table can be designed so that, when a table top is mounted on the table frame, it runs beneath the table top and / or parallel to it. In particular, the intake space can run horizontally. The intake space preferably forms a retraction plane that can be moved with the table frame, which can, for example, be horizontal. The section of the cable chain is preferably retracted into the intake space along this retraction plane.
[0074] The intake space can be a hollow space located in or beneath the tabletop. For example, the intake space could be a cable duct. It can also be formed by the gap between a double tabletop.
[0075] The deflection device of the table frame or table is preferably provided and / or designed such that the section of the cable chain that extends along the table leg and / or is retracted into the retraction space runs vertically along the table leg and is deflected at the deflection device such that it is subsequently introduced horizontally into the retraction space. The section of the cable chain can be deflected at the deflection device, for example, by 70° to 110°, 80° to 100°, or approximately 90°. For this purpose, the deflection device can have an inner bracket (on the inside of the curved section) and / or an outer bracket (on the outside of the curved section).
[0076] The deflection device can also have lateral guide elements or guide rails, which can in particular be provided and / or designed in such a way that it is made more difficult for the cable chain to slip out in one or more directions transverse to its longitudinal direction.
[0077] The retraction mechanism of the table frame or table is preferably designed and / or configured such that the cable chain is permanently subjected to tensile load and / or pre-tension. A tensile load and / or pre-tension is preferably applied regardless of the position and / or adjustment of the table leg. However, the strength of the tensile load and / or pre-tension can vary depending on the height of the table leg.
[0078] The tensile load and / or pre-tension preferably always holds the cable chain along the table leg in a desired operating position. In this operating position, the cable chain preferably extends taut along the table leg, i.e., preferably substantially perpendicularly or vertically. The tensile load and / or pre-tension ensures that the section of the cable chain does not bulge when the table leg is raised or lowered, in particular not in the direction of the second coordinate axis Y (positive and / or negative), and / or buckle, in particular not in the direction of the third coordinate axis Z (positive and / or negative). For this purpose, the retraction device preferably provides a tensile and / or pre-tensioning force of at least 3 N, 10 N, at least 20 N, at least 30 N, at least 50 N, at least 75 N, at least 100 N or at least 150 N (approximately 0.3 kg, 1 kg, 2 kg, 3 kg, 5 kg, 7.5 kg, 10 kg or 15 kg tensile force).The tensile load and / or pre-tension also ensures that the cable chain is automatically returned to the operating position even if it is touched and / or manipulated by the user of the table.
[0079] The retraction device is further preferably provided and / or configured to retract the cable chain into the retraction space when the table frame is lowered. For this purpose, the retraction device can engage a second end of the section, which is preferably opposite the first end. The section that extends along the table leg and / or is retracted into the retraction space preferably comprises at least 5 or at least 10 chain links (particularly between the first and second ends).
[0080] To retract the section of the cable chain, the retraction device preferably has a traction mechanism. This can be fixed to the section of the cable chain (preferably at the second end) and to the table frame (e.g., in the retraction space).
[0081] According to a first variant, the traction means can comprise one or more spring elements that are deflected when the table is raised and provide a restoring force when it is lowered. One or more helical or spiral springs and / or one or more rubber bands can serve as spring elements. The traction means can also comprise a cable section. This cable section can be provided with a spring (such as a helical and / or spiral spring) to provide a restoring force. Alternatively or additionally, the cable section can be wound using a spiral spring.
[0082] According to a further variant, which can be provided alternatively or in addition to the previous one, the retraction device and / or the traction means are coupled to the height adjustment mechanism of the table. The retraction device can comprise a cable piece connected to the height adjustment mechanism. To compensate for tolerances and / or to provide the preload force, the cable piece can comprise a spring element (e.g., a coil spring).
[0083] According to a further variant, the traction means may comprise a motor.
[0084] The retraction device can be located in the retraction space, for example, in a cable duct or between the upper and lower sections of a double-walled tabletop. Alternatively or additionally, the retraction device can be located below the retraction space or extend at least partially below it.
[0085] The invention therefore provides various options for better adapting cable guides and cable chains to the respective installation situation. Particular advantages arise for the attachment of cable guides and cable chains to table legs and tables. This particularly achieves advantageous cable routing along the various sections of the table leg and / or in a cable duct of the table. Furthermore, the cable routing along the floor to the table can be improved. With the cable guides and cable chains of the invention, a continuous cable chain can be realized along the floor and the entire table leg, which has a homogeneous appearance with consistent sheath bodies. Furthermore, the guided cables can be inserted into the cable guide or cable chain easily and safely and in the same way along the entire cable guide or cable chain, which greatly simplifies installation and modification.The cable guides and cable chains according to the invention can ensure secure cable routing along the entire cable guide or cable chain, especially in transition areas, such as the transition area from the table leg to the floor, from the fixed to the extendable part, and / or from the extendable part to the cable duct or tabletop. This significantly reduces the risk of damaging the guided cables.
[0086] Preferred embodiments of the invention are described below by way of example with reference to the drawings. These are merely schematic representations that often omit other (optional) structures to clarify certain aspects or also consider various optional, interrelated aspects in one representation. In this context, the same reference numerals indicate equivalent, similar, comparable, or identical components in the illustrated embodiments.

[0088] Fig. 2 schematically illustrates a table leg 1 according to an embodiment of the invention. The table leg 1 has a stationary part 2 and an extendable part 3. Furthermore, a cable guide 10 is provided on the table leg 1 for guiding cables from a floor outlet 5 into the area of a table top (not shown) (e.g., to a cable socket or a cable duct in the table top). For this purpose, the cable guide has a cable chain 70 comprising a first section A, a second section B, and a third section C. The first section A serves to guide the cables along the stationary part 2, while the second section B guides the cables along the extendable part 3 and provides sufficient play and / or length for raising and lowering the table leg 1.The third section C extends, in particular, along the floor to guide the cables from the floor outlet 5 to the table leg 1 (and in particular to the first section A of the cable chain 70). In particular, the third section C can also bridge the transition area at the lower end of the table leg 1.
[0089] For a more detailed examination of the cable guide 10, the coordinate system X, Y, Z can be used, which is shown in Fig. 1A and Fig. 1B. Since the coordinate system can be shifted along the cable chain 70, the first coordinate axis X extends along the first section A preferably in the vertical direction and / or parallel to the table leg 1 (preferably with the positive coordinate direction pointing upwards). The second coordinate axis Y and the third coordinate axis Z can accordingly be horizontal and / or parallel to the floor along the first section, with the second coordinate axis Y preferably pointing from the longitudinal axis of the cable chain 70 and / or from the longitudinal axis of the respective chain link to the table leg 1.
[0090] After the cable chain 70 is attached to the table leg 1, the position of the chain links of the first section A is preferably fixed or can only be adjusted using the respective fastening device. This prevents, in particular, bulging of the cable chain 70 along this first section A in the direction of the coordinate axis Y (particularly in the negative coordinate direction). Furthermore, buckling in the direction of the coordinate axis Z (positive and / or negative coordinate direction) is prevented.
[0091] The cable chain 70 can also be designed along the first section A such that the cable chain 70 is not compressible. This ensures a consistent distance between the links of the cable chain 70.
[0092] Along the second section B, adjacent links of the cable chain 70 are pivotable relative to one another about exactly one axis of rotation, which is perpendicular to the longitudinal axis of the cable chain 70. In particular, pivotability about the third coordinate axis Z, which is also preferably horizontal along the entire second section B, is possible. This can impart the mobility of a tank or track chain to the second section B. On the one hand, this allows the cable chain 70 to sag along the second section B, so that the cable chain 70 can roll off the table leg 1 and sag along this section B. On the other hand, it prevents the cable chain 70 from buckling along the second section B in the direction of the third coordinate axis Z (positive and / or negative coordinate direction). In the embodiment of Fig. 2, the second section B thus has exactly one degree of freedom more than the first section A of the cable chain 70 (pivotability about a rotation axis).
[0093] By avoiding the compressibility of the cable chain 70 along the second section B, a constant distance between the chain links of the second section B can also be achieved.
[0094] In the illustrated embodiment, the second section B is connected at its first end directly to the first section A. The opposite second end of the second section B can be fixed to the table leg 1 or, preferably, to a table top (not shown).
[0095] The third section C should be able to guide the cables along the floor as flexibly as possible, whereby in particular a specific outlet (such as a floor outlet 5) should be able to be reached and / or other objects bypassed.
[0096] For this purpose, the cable chain 70 along the third section C is preferably designed such that adjacent chain links can be pivoted relative to one another about at least a first axis of rotation. This first axis of rotation is preferably congruent with the second coordinate axis Y along the third section C. For the chain links of the third section C that run on the floor, the first axis of rotation is preferably provided substantially vertically and / or parallel to the table leg 1 in order to achieve mobility in the floor plane. The second coordinate axis Y can therefore point downwards for the chain links that run on the floor. The first coordinate axis X and the third coordinate axis Z can therefore be horizontal.
[0097] To enable a clean transition at the lower end of the table leg 1, the cable chain 70 can further be designed along this section C such that adjacent chain links can be pivoted relative to one another about a second axis of rotation, which is perpendicular to the longitudinal direction of the cable chain 70 and perpendicular to the first axis of rotation. This second axis of rotation can be congruent with the third coordinate axis Z and / or run essentially horizontally. As a result, the cable chain 70 can bend away from the floor along the third section C and thus guide the cables to the first section A of the cable chain 70. In addition, unevenness in the floor can be compensated for and the cable chain 70 can be guided along the third section C, for example, over other objects (such as other cable chains). The third section C can also be designed such that the chain links can be moved relative to one another along the longitudinal axis of the cable chain 70.The cable chain 70 can therefore be compressible along this section C.
[0098] A cable guide 10 is thus provided on the table leg 1, which comprises a cable chain 70 with three sections A, B, C, each of which has a different mobility and / or a different number of degrees of freedom between adjacent chain links. The second section B has at least one or exactly one degree of freedom more than the first section A. Furthermore, the third section C preferably has at least one, at least two or even three degrees of freedom more than the second section B. The third section C can therefore have at least two, at least three or even four degrees of freedom more than the first section A. Nevertheless, the cable chain 70 has identical sheath bodies along all three sections A, B, C (i.e. in particular sheath bodies with identical cross-sections and / or identical external dimensions).In addition, the chain links along all three sections can have identical chain spacings and / or identical connecting bodies. Furthermore, the sheathing bodies and / or the connecting bodies along all three sections can be made of the same material. The sheathing bodies can, among other things, have identical entry openings for the guided cables. This ensures that the guided cables along all three sections can be inserted into the cable chain 70 in the same way, even after the cable chain has been mounted on table leg 1. In addition, a homogeneous appearance is ensured. Using the same dimensions for the chain links also prevents components from protruding. This minimizes the risk of injury and ensures the greatest possible clearance for the user's legs.
[0099] Appropriate mobility of the cable chain along sections A, B, and C can be achieved by various measures. This includes, in particular, the design of one or more connecting bodies of the chain links and their receptacles. Furthermore, it is possible to provide specific locking elements between the chain links of a section, by means of which the mobility can be selectively restricted or completely prevented (see, for example, the locking elements described in the parallel German patent application of the present applicant of the same date entitled "Table Leg," the disclosure content of which is fully incorporated by reference into the present application). Finally, according to an embodiment not according to the invention, the cable chain 70 can also be rigidly designed along a section (in particular along the first section A) by using a mounting or guide rod.
[0100] Fig. 3A shows the cable guide 10 of Fig. 2 according to one embodiment. The first section A is rigid according to an embodiment not according to the invention. As in Fig. 3B , in which some of the chain links of the first section are hidden, this can be achieved, for example, via a rigid mounting rod 30, via which the chain links of the first section A are connected. The first section A can optionally (as in Fig. 3B), be attached to the table leg by means of appropriate fastening devices which engage the mounting rod 30.
[0101] Fig. 3C shows a further possibility not according to the invention for forming a rigid section A. Here, at least some of the chain links of section A are replaced by a rigid mounting profile 40. Its outer dimensions preferably correspond substantially to the outer dimensions of the casing bodies of the chain links of the cable chain 70 in order to achieve the most homogeneous appearance possible despite the use of the mounting profile 40 and to prevent any risk of injury from protruding parts. In this case, the first section A can be fastened to the table leg via the mounting profile 40. Alternatively or additionally, the profile 40 can be fastened to the table leg by the cable chain 70, wherein the cable chain 70 can then in turn be fastened to the table leg by fastening elements.Such fastening elements are described, for example, in the parallel German patent application filed by the present applicant on the same date, entitled "Device for Fastening a Cable Guide Chain," the disclosure of which is also incorporated in its entirety by reference. The profile and / or the cable guide chain can be arranged close (e.g., at a maximum of 15 mm, a maximum of 10 mm, a maximum of 5 mm, or a maximum of 2 mm) to the table leg or flush (no gap) with it.
[0102] Fig. 4A shows a table leg 1 with a cable guide 100 according to a further embodiment. The cable guide 100 of Fig. 4A differs essentially only in the design of the second section B of the cable chain 70 from the cable guide 100 of Fig. 2 - Fig. 3C . With regard to the design of the first section A and the third section C, reference can therefore be made to the preceding explanations.
[0103] In the cable guide 100, the second section B of the cable chain 70 runs essentially along the extendable part 3 of the table leg 1. The second section B ends in a cable duct K, which is usually provided under a table top (not shown). The second section B is particularly designed such that it is pushed and / or retracted into the cable duct A when the table leg 1 moves down. If, however, the table leg 1 moves up, the second section B is pulled out of the cable duct K. This compensates for the change in length of the table leg 1 when the extendable part 3 is extended.
[0104] The second section B can be designed such that it is passively inserted into the cable duct K when the table is lowered, preferably without bulging along the extendable part 3 (in particular not in the negative direction of the coordinate axis Y) or buckling (in particular in the positive and / or negative direction of the third coordinate axis Z). For this purpose, the second section B can be designed such that the higher chain link of two adjacent chain links can only pivot about the third coordinate axis Z relative to the lower chain link, preferably only in the negative direction of rotation. In the positive direction of rotation, the pivoting about the third coordinate axis is preferably completely blocked or limited to a minimum, approximately 2°, 5°, or 10°, while in the negative direction, a pivoting of at least 10°, at least 20°, at least 30°, at least 40°, at least 50°, or at least 60° is permitted.As a result, the cable chain 70 can only roll off the table leg 1 along the second section B in the negative direction of the second coordinate axis Y. However, bulging in this direction and / or buckling in the direction of the coordinate axis Z is prevented along the extendable part 3 of the table leg 1. Likewise, bulging and / or buckling in the cable duct K is prevented. This ensures that the second section B can only be moved along the cable duct K (in particular into it) when the table leg 1 is lowered.
[0105] According to another variant, which is Fig. 4B, the second section B can also be actively retracted into the cable duct K. For this purpose, a spring mechanism with one, two or more springs 90 (e.g., coil springs) can be provided in the cable duct. These are preferably tensioned by pulling the second section B out of the cable duct K when the table leg 1 is lowered. When the table leg 1 is lowered, the cable guide 100 (in particular the second section B) is then actively retracted into the cable duct K by the restoring force of the springs 90. The mechanism can act in particular on the second section B (e.g., at its end).
[0106] The fourth section D can be attached at one end to the second section B or to an adapter. At its other, opposite end, the fourth section B can terminate in the area of a cable outlet or cable duct in the tabletop.
[0107] As further stated in Fig. 4B, the cable guide 100 can also have a fourth section D, which preferably adjoins the second section B and is provided in the cable duct K. The fourth section D can have just as many degrees of freedom as the second section B. However, adjacent chain links of this section can preferably be moved relative to one another by at least one, at least two or even three degrees of freedom more than along the second section B. The fourth section D is preferably designed such that adjacent chain links can be rotated relative to one another at least along a part of this section about a first axis of rotation, which runs substantially perpendicular to the longitudinal axis of the cable chain and substantially in the vertical direction. As shown in Fig. 4B, the fourth section D can thereby be designed such that it forms a U-shaped section in the cable duct K. This section can compensate for the change in the length of the second section B, which extends along the cable duct K when the table is raised or lowered. The first axis of rotation along the U-shaped section is preferably vertical and / or perpendicular to the first axis of rotation of the second section B.
[0108] To achieve a vertical arrangement of the rotation axis of the fourth section D, the cable chain 70 can be configured along the fourth section D such that adjacent chain links can rotate relative to one another about the longitudinal axis of the cable chain. In this case, the fourth section D can be twisted in the form of a helix in front of the U-shaped section in order to arrange the chain links accordingly along the U-shaped section. For this purpose, the chain links can be designed such that their connecting body can deform somewhat reversibly (elastically) (particularly when using a double plug or when using connecting eyes). Alternatively or additionally, a certain amount of play can be present between the connecting body and the receptacle of the adjacent chain link, which can also allow rotation about the longitudinal axis.
[0109] Alternatively or additionally, the second section B and the fourth section D can be connected via an adapter that arranges the two sections offset by an angle of 90° relative to each other around the longitudinal axis of the cable chain. In this case, the fourth section D can be formed by a different type of cable chain than the second section B. This allows, in particular, the use of a cable chain with smaller sheathing bodies (in particular, narrower sheathing bodies) and / or other connecting bodies along the fourth section. This allows the cable duct K to be designed flatter, which increases legroom and thus the comfort of the desk users.
[0110] A corresponding adapter 300, which can also form an independent aspect of the present invention, is shown by way of example in Fig. 5. The adapter 300 has a first connecting section 301 for a first cable chain 70 (which can also be referred to as the first cable chain section) and a second connecting section 302 for a second cable chain 80 (which can also be referred to as the second cable chain section). The first connecting section 301 is designed such that a first type of cable chain can be coupled thereto (in the exemplary embodiment shown, a cable chain 70 with two plug attachments 73). The second connecting section 302, on the other hand, is designed such that a different type of cable chain can be coupled thereto (in the exemplary embodiment shown, a cable chain 80 with connecting bodies 73 in the form of connecting eyes, into which connecting pins 76 of an adjacent chain link can engage).In the illustrated embodiment, the first connecting section 301 is therefore designed as a plug receptacle with snap-in devices for the plug lugs, while the second connecting section 302 has projections that engage in the connecting eyes of the first chain link of the second cable chain 80.
[0111] Fig. Figure 6 shows a table frame according to the invention with a table leg 1 according to the invention according to a further variant. In this case, a cable chain 70 or cable guide according to the invention with sections A, B, C, and / or D of varying mobility can be used. However, a cable chain with a uniform mobility can also be used.
[0112] The table frame from Fig. 6, a section of the cable chain 70 is fixed at its first end 50 to the table leg by means of a fastening device. In the illustrated embodiment, the fastening device is provided at the lower end of the table leg 1, but can in principle also be arranged higher, for example in the area of the fixed part 2 of the table leg 1. This applies in particular if the fixed part is formed by the outer part of a telescopic leg. If the fixed part is formed by the inner part of a telescopic leg, the first end 50 is preferably attached to the base of the table leg 1 and / or to the floor.
[0113] The section of the cable chain 70 that extends along the table leg is provided with the reference symbol B in the illustrated embodiment to clarify that it can be designed according to the second section B of the previously described cable chain. However, the section can also have different degrees of freedom along its length and, in particular, can be designed along the fixed part 2 according to the section A of the cable chains according to the invention (i.e., e.g., rigid). A rigid profile 40 can also be used along the fixed part 2 (see Fig. 3C). The profile is preferably designed as a fastening device and thus fixes the connected cable chains.
[0114] Section B is guided by a deflection device 92 into a horizontal cable duct (not shown), in which a retraction device is provided. This pulls on a second end 60 of section B to tension it and retract it into the cable duct as the table leg 1 is lowered. The deflection device 92 is formed by an inner bracket provided on the inside of the curve. Additionally, an outer bracket (not shown) can be provided (on the outside).
[0115] In the illustrated embodiment, the retraction device is formed by two helical springs 90. These are fastened on the one hand to the second end 60 of section B. On the other hand, they are anchored to the table frame (e.g., in the cable duct) (not shown). Since the springs 90 are pretensioned, section B of the cable chain is tightened between the first end 50 and the second end 60, thereby preventing bulging in the direction of the Y coordinate axis and buckling in the direction of the Z coordinate axis. The springs 90 are deflected when the table leg 1 is raised and section B is pulled out of the cable duct to compensate for the extension of the table leg. When the table leg 1 is lowered, section B is then retracted back into the cable duct due to the restoring force of the springs.
[0116] At the second section B (in particular at its second end 60) a section D can be formed according to the previous description (see, for example, the description of Fig. 4B). Alternatively or additionally, the cable chain may have a section C according to the previous description. This section may have a greater number of degrees of freedom than section B. In particular, section C may be designed and / or provided to extend along the floor.
[0117] Fig. Figure 7 shows a further variant of the table legs and table frames according to the invention. It is particularly clear that the section D, which adjoins the section B, can also be guided back by rotating adjacent elements around the third coordinate axis Z in the cable duct K and form a U-shape. This, as well as the configuration of Fig. 4B to compensate for the change in the length of section B provided in the cable duct K when the table leg 1 is raised or lowered.
[0118] Fig. 8A and Fig. 8B show a cable chain 70 according to the invention on a table or table frame according to the invention with an extendable table leg 1. The cable chain 70 has at least a first section A and a second section B, wherein the cable chain 70 sags along the second section B. In this respect, the cable chain 70 is similar to that of Fig. 2 and Fig. 3A to Fig. 3C similar. Fig. 8A and Fig. 8B illustrate, however, that the cable chain 70 can be positioned not only along the table leg 1, but also via a base plate 110 on the floor. The base plate 110 can have a mounting rod in order to arrange the section A substantially vertically. The longitudinal axis of the cable chain in the first section A can therefore form an angle α with the floor (ie the horizontal), which can be, for example, 80° to 100°, 85° to 95° or approximately 90°. The length ratios of the sections A and B explained below and the minimum distances H and h can, of course, also occur in other embodiments, for example in those according to Fig. 2 or Fig. 3A to Fig. 3B . This also applies to the distances a and b between the chain links.
[0119] The unrolled length of section A may optionally be at least 5%, at least 10%, at least 20% or at least 30% of the combined unrolled length of sections A and B.
[0120] The distance h between the lowest point of the chain links in the sagging area and the floor is preferably at least 2 cm, at least 5 cm, at least 10 cm, or at least 20 cm. Depending on the design of the cable chain, these dimensions can also apply to a minimum distance H between the center line of the cable chain in the sagging area and the floor when the table leg 1 or the table frame is lowered. For this purpose, the distance H and / or the distance h when the table leg or table frame is lowered can be less than the length and / or height of section A (see Fig. 8B). In a middle position of the table leg 1 or table frame, the distance H and / or the distance h can approximately correspond to the length and / or height of section A (see Fig. 8A). Finally, the distance H and / or the distance h may be greater than the length and / or height of section A when the table leg 1 or the table frame is fully extended (not shown).
[0121] As further stated in Fig. As shown in Figure 8A, the distance a between chain links of the first section A can optionally be smaller than the distance b between the chain links of the second section B, for example, by at least 10%, at least 20%, at least 50%, or at least 60%. Thus, the distance a can be at least 2 mm, at least 5 mm, at least 10 mm, or at least 20 mm smaller than the distance b.
