Definitions

  • This disclosure relates to a universal carrier for mounting on vertical support profiles and an arrangement with such a universal carrier and vertical support profiles of a rack.
  • Rack systems or racks are frameworks or structures (possibly with housing walls) that accommodate electronic devices, particularly computer systems such as servers.
  • the racks generally have vertical support profiles arranged a certain distance apart. Between the support profiles, universal carriers or carrier rails can be installed, on which in turn electronic devices such as servers or additional electronic components (socket strips, connection modules, etc.) can be mounted.
  • a universal carrier generally comprises at least two parts, a base part and a telescoping part, which are movable axially relative to one another. Therefore, the extension length of the universal carrier can be adapted within certain limits to the spacing between the vertical support profiles of the rack, by moving the telescoping part relative to the base part.
  • Known solutions for universal carriers provide a spring-loaded seating of the telescoping part relative to the base part.
  • the telescoping part and the base part can be inserted one inside another against the spring force of a flexible or elastic element such that the universal carrier can be clamped between the vertical support profiles of the rack. Due to the spring force of the flexible element, the telescoping part and the base part are driven apart in the installed state and press against the vertical support profiles of the rack.
  • suitable installation elements such as catch pins or projections, the universal carrier can be fixed securely and stably to the vertical support profiles in corresponding counter-engagement elements such as profile openings.
  • a universal carrier can be mounted easily and quickly in this manner.
  • the spring arrangement for conventional systems is set to the largest extension length of the universal carrier, with the base part and the telescoping part being pushed together for smaller extension lengths if the support profiles have a smaller spacing between them.
  • a universal carrier for installation on vertical support profiles of a rack including at least a base part and a telescoping part movable axially with respect to the base part, wherein 1) the telescoping part and the base part connect via a flexible element such that the telescoping part and the base part form a predetermined extension length of the universal carrier when the flexible element is relaxed and can be pushed together against a force of the flexible element, and 2) the flexible element can be fixed in a plurality of axial positions on the base part and/or on the telescoping part such that the extension length of the universal carrier can be adjusted by varying the axial position of the flexible element on the base part and/or on the telescoping part.
  • FIG. 1 shows a universal carrier
  • FIG. 2 shows a detailed sectional cutout of the universal carrier according to FIG. 1 .
  • FIG. 3A shows an arrangement with a universal carrier according to FIGS. 1 and 2 and vertical support profiles in a first spacing.
  • FIG. 3B shows an arrangement with a universal carrier according to FIGS. 1 and 2 and vertical support profiles in a second spacing.
  • the universal carrier for installation on vertical support profiles of a rack, wherein the universal carrier comprises at least a base part and a telescoping part.
  • the telescoping part is movable axially relative to the base part, the telescoping part and the base part being connected via a flexible element such that the telescoping part and the base part form a predetermined extension length of the universal carrier when the flexible element is relaxed.
  • the telescoping part and the base part can additionally be pushed together against a force of the flexible element, wherein the flexible element can be fixed in a plurality of axial positions on the base part and/or on the telescoping part such that the extension length of the universal carrier can be adjusted by changing the axial positions of the flexible element on the base part and/or on the telescoping part.
  • the extension length of such a universal carrier can be adapted to different spacings of the vertical support profiles of a rack.
  • the extension length between the telescoping part and the base part, which are connected via the flexible element can be adjusted without the flexible element having to be stressed (elongated or compressed).
  • the telescoping part and the base part are pushed together a certain distance against a force of the flexible element for installation of the universal carrier on vertical support profiles of a rack.
  • the universal carrier can be inserted between the vertical support profiles and finally braced on the vertical supports against the force of the flexible element since the telescoping part and the base part are driven apart by the force of the flexible element.
  • An advantage of the universal carrier is that by adjusting the position of the flexible element on the base part and/or on the telescoping part, the extension length of the universal carrier can be adjusted independently of the stress, e.g., the spring travel of the flexible element. That means that the extension length of the universal carrier, i.e. the relative position of the telescoping part and the base part, with the flexible element relaxed can be adjusted by changing the position of the flexible element on the base part and/or on the telescoping part.
  • a subsequent pushing together of the telescoping part and base part to brace the universal carrier during and after installation on the vertical support profiles leads to a stress on the flexible element that is essentially the same for different extension lengths of the universal carrier. That means that the flexible element is stressed nearly equally for different spacings of the support profiles, independently of the extension length of the universal carrier. Overstressing or over-elongation or an excessively strong compression and resulting overload or lasting (plastic) deformation of the flexible element during an adjustment of the universal carrier's length to a spacing of support profiles can no longer occur with this solution.
  • the flexible element is preferably a spring element fixed at a first end to the base part and at a second end to the telescoping part.
  • the spring element can be implemented, for example, as a spiral spring with a predetermined length in the relaxed state.
  • the spring element can be elongated or compressed by a defined spring travel.
  • this travel of the spring element is independent of the actual extension length of the universal carrier due to the variable position of the spring element on the base part and/or the telescoping part for different extension lengths.
  • a manually operable locking element that can be engaged in a plurality of axial positions on the base part and/or on the telescoping part is preferably arranged on the base part and/or on the telescoping part, the flexible element being fixed to the locking element of the base part and/or the telescoping part.
  • a simple variation of the axial position of the flexible element on the base part and/or on the telescoping part is possible using the manually operable locking element.
  • a user only has to operate the locking element and move it axially on the base part and/or on the telescoping part to vary the position of the flexible element on the base part and/or on the telescoping part.
  • the locking element can engage in the respective predetermined position on the base part and/or on the telescoping part and be stably fixed in place.
  • a locking element as described can be furnished in different forms either on the base part or on the telescoping part or on both the base part and the telescoping part to vary the position of the flexible element such that the extension length of the universal carrier can be adjusted.
  • the problem is also solved by an arrangement with a universal carrier of the type mentioned above and vertical support profiles of a rack, wherein the vertical support profiles are arranged a predetermined distance apart from one another and the universal carrier is arranged between the vertical support profiles.
  • the flexible element is preferably arranged in a predetermined axial position among the plurality of axial positions on the base part and/or on the telescoping part so that the extension length of the base part and the telescoping part is adapted to the spacing of the vertical support profiles.
  • the flexible element is advantageously tensioned so that the base part and the telescoping part of the universal carrier are pushed apart by the force of the flexible element and brace the universal carrier between the vertical support profiles.
  • FIG. 1 shows a universal carrier 1 with a base part 2 and a telescoping part 3 .
  • the telescoping part 3 can be moved axially relative to the base part 2 , the base part 2 formed such that it at least partially surrounds the telescoping part 3 in the manner of a bracket so that the telescoping part 3 is enclosed by the base part 2 and runs in the base part 2 if axially displaced.
  • Mounting elements 13 and 22 that serve to mount the universal carrier 1 on vertical support profiles of a rack are respectively arranged on the end faces of the base part 2 and the telescoping part 3 .
  • Vertical support profiles generally comprise openings in a predetermined profile spacing into which the universal carrier can be inserted or hooked.
  • the mounting elements 13 that are shown with pin shapes for the sake of example in FIG. 1 can be inserted into such openings of the vertical support profiles.
  • the mounting elements 22 in FIG. 1 are designed with mounting holes and a locking pin, the base part 2 being be installed with its mounting holes 22 on pin-shaped mounting profiles of a vertical support and locked in place with the locking pin.
  • the universal carrier 1 is designed, for example, such that a telescoping rail for pulling an electronic device out of a rack can be arranged on the universal carrier 1 . It is also possible, however, to furnish one or more support brackets on the universal carrier 1 to hold a housing of an electronic device or to hold additional electronic components such as connection bars or components. Thus, the universal carrier 1 can be used for universal mounting and support of electronic components in a rack.
  • the telescoping part 3 can be displaced axially relative to the base part 2 .
  • the base part 2 and the telescoping part 3 connect via a flexible element 4 furnished in this case as a spiral spring for the sake of example.
  • One end of the flexible element 4 (the right end of the flexible element 4 in this case) connects to the telescoping part 3 and the other end of the flexible element 4 (the left end of the flexible element 4 in this case) connects to the base part 2 .
  • the flexible element 4 is relaxed, the base part 2 and the telescoping part 3 forming a defined extension length of the universal carrier 1 .
  • the base part 2 and the telescoping part 3 can be pushed together such that the flexible element 4 is pulled apart and stretched.
  • the telescoping part 3 and the base part 2 are pushed one into another, the right end of the flexible element 4 on the telescoping part 3 is moved to the right relative to the base part 2 .
  • the left end of the flexible element 4 on the base part 2 is pushed to the left relative to the telescoping part 3 .
  • the universal carrier 1 shortened somewhat in this manner, can be inserted between two vertical support profiles of the rack and finally installed and braced against the force of the flexible element 4 on the support profiles. Due to the force of the stretched flexible element 4 , the telescoping part 3 and the base part 2 are driven apart in the installed state and press against the vertical support profiles of the rack so that the universal carrier 1 can be locked stably to the vertical support profiles.
  • the flexible element 4 connects via a locking element 5 to the base part 2 .
  • the locking element 5 can be operated manually and, in the example according to FIG. 1 , has catch projections 15 that can engage in grooves 12 on the base part 2 .
  • the grooves 12 are arranged at different positions P 1 , P 2 , P 3 through Pn on the base part 2 .
  • the locking element 5 is locked at position P 3 in FIG. 1 , for example. Due to the locking element 5 , the flexible element 4 can therefore be fixed at different positions of the base part 2 of the universal carrier 1 . This means that when the position of the locking element 5 is changed and the flexible element 4 is relaxed, the position of the telescoping part 3 relative to the base part 2 , and thus the extension length of the universal carrier 1 , can be varied.
  • the locking element 5 By detaching the locking element 5 , for example, the entire arrangement of the locking element 5 , the flexible element 4 and the telescoping part 3 can be shifted to the left, with the telescoping part 3 being pulled out of the base part 2 . Subsequently, the locking element 5 can, for example, again be locked in the position P 1 so that the telescoping part 3 and the base part 2 form a larger extension length than was the case with the position P 3 of the locking element 5 in FIG. 1 .
  • the extension length of the universal carrier 1 can be adjusted independently of the stress on the flexible element 4 by fixing the locking element 5 at different positions P 1 through Pn on the base part 2 .
  • the position P 1 through Pn of the locking element 5 on the base part 2 is changed by pushing the telescoping part 3 and the base part 2 together for installation, the flexible element 4 is stretched and stressed essentially uniformly at different extension lengths of the universal carrier 1 .
  • a change of the extension length of the universal carrier 1 thus does not imply any overload and possibly lasting (plastic) deformation of the flexible element 4 .
  • FIG. 2 shows an enlarged cutout of the universal carrier 1 according to FIG. 1 .
  • a part of the base part 2 and of the telescoping part 3 which are connected via the flexible element 4 , can be recognized in FIG. 2 .
  • the flexible element 4 is fixed at its right end to the telescoping part 3 and at its left end to the locking element 5 .
  • the locking element 5 is in turn fixed to the base part 2 .
  • the catch projections 15 engage with the grooves 12 on the base part 2 so that the locking element 5 is fixed at the position P 3 on the base part 2 .
  • the locking projections 15 can be detached from the grooves 12 in the position P 3 so that the locking element 5 can be shifted to the left, for example, and locked into one of the positions P 1 or P 2 .
  • the flexible element 4 is locked further to the left on the base part 2 so that the engagement point of the flexible element 4 on the base part 2 is changed. Thereby the telescoping part 3 is pulled to the left out of the base part 2 when the flexible element 4 remains relaxed. In this way, the extension length of the universal carrier 1 is increased.
  • the flexible element 4 is only tensioned during installation of the universal carrier 1 and is thus independent of the extension length adjustment of the universal carrier 1 .
  • FIGS. 3A and 3B adaptation of the extension length of the universal carrier 1 to different spacings Y 1 and Y 2 of the vertical supports 6 a, 6 b of a rack 1 is illustrated in FIGS. 3A and 3B .
  • FIG. 3A shows an arrangement with vertical support profiles 6 a, 6 b of a rack and a universal carrier 1 of the type mentioned above.
  • the vertical support profiles 6 a, 6 b are arranged with a first spacing Y 1 relative to one another.
  • the universal carrier 1 is arranged between the vertical support profiles 6 a, 6 b.
  • the universal carrier 1 comprises the base part 2 and the telescoping part 3 , which are arranged in a predetermined position relative to one another so that the universal carrier 1 extends in a spacing Y 1 between the vertical support profiles 6 a, 6 b.
  • the locking element 5 is locked in the position P 3 on the base part 2 in the example according to FIG. 3A .
  • a predetermined extension length of the universal carrier 1 is defined, which is adapted to the spacing Y 1 .
  • the flexible element 4 which connects the base part 2 and the telescoping part 3 of the universal carrier 1 non-positively, further has a defined extension X.
  • the flexible element 4 is advantageously stretched in the extension X such that it exerts a force on the telescoping part 3 and the base part 2 at the respective engagement points (connection points to the telescoping part 3 and the base part 2 ) such that the telescoping part 3 and the base part 2 are pushed apart.
  • the telescoping part 3 is pushed to the left against the left vertical support profile 6 a and the base part 2 is pushed to the right against the right vertical support profile 6 b.
  • the universal carrier 1 according to FIG. 3A is braced between the vertical support profiles 6 a, 6 b and stably fixed to the vertical support profiles 6 a, 6 b with a spacing Y 1 .
  • the universal carrier 1 can be locked to the vertical support profiles 6 a, 6 b by mounting elements 13 and 22 , for example, as explained for FIG. 1 .
  • FIG. 3B shows an arrangement with vertical support profiles 6 a, 6 b and a universal carrier 1 wherein, however, the vertical support profiles 6 a, 6 b are arranged with a spacing Y 2 different from FIG. 3A , that is larger than the spacing Y 1 of FIG. 3A .
  • the locking element 5 is not engaged in the position P 3 (as shown in FIG. 3A ), but in position P 1 .
  • the telescoping part 3 is pulled further out of the base part 2 so that the overall extension length of the universal carrier 1 is adapted to the second spacing Y 2 .
  • the flexible element 4 has an extension X in FIG. 3B that is nearly equal to the extension X according to FIG. 3A .
  • the flexible element 4 is not stressed substantially more strongly or weakly than in FIG. 3A , because the engagement point of the flexible element 4 on base part 2 is offset in comparison to the version in FIG.
  • the flexible element 4 is advantageously stretched somewhat in FIG. 3B so that a tensioning force is exerted on the base part 2 and the telescoping part 3 for bracing the universal carrier 1 between the vertical support profiles 6 a and 6 b.
  • a locking element 5 for variable positioning of the flexible element 4 can also be arranged on telescoping part 3 in examples not shown. It is possible, for example, to fix the flexible element 4 at an invariable position on base part 2 , with a variable position fixation of the flexible element 4 on the telescoping part 3 being furnished via a locking element 5 . This ultimately implies a reversal of function between base part 2 and telescoping part 3 in the illustrated principle to adjust the extension length of a universal carrier 1 .
