Definitions

  • This switch cabinet key has a central body with four radially protruding key arms. At the outer ends of the key arms, tool heads are formed which have different head shapes for actuating different switch cabinet locks.
  • the profiles are preferably at an angle of 45 to 60 degrees, preferably 45 or 60 degrees angularly or rotationally offset to one another.
  • linear offset or linear offset means according to the invention that the second drive profile is arranged in relation to the first drive profile on a different plane in the direction of longitudinal extent along the longitudinal axis of the key arm.
  • the invention now combines these types of offset in all possible combinations, multiple times in each key arm if possible.
  • This reduction to the edge engagement represents an essential aspect and an essential insight of the invention.
  • This also offers the advantage that the key or joining partner that can be actuated with the smaller drive profile in the secondary key arm tool level can be made shorter because it is only completely in exceptional cases must protrude into the secondary key arm tool level.
  • Preferred embodiments include that the second drive profile is also arranged offset in rotation with respect to the first drive profile.
  • an angle between 0 and 45 degrees of rotation has proven to be expedient; particularly preferred results and stable wall thicknesses of the key arm were achieved at 45 degrees of offset.
  • the second Drive profile is only partially formed or is pronounced in the first key arm tool level and only then is the full drive profile formed in a second or secondary key arm tool level below, which is therefore formed in the direction of the main body in the key arm.
  • This partial formation of the second drive profile in the primary key arm tool level thus already provides a "pre-grip surface" for transmitting smaller torques of the second drive profile, but the full torque only when inserted into the second key arm tool level below the key arm tool level.
  • this inside collar has the notch effect, in particular on the base of the flanks of the beards of the double beard considerably reduced, so that with such a double bit, about 30-50% higher torques can be transmitted than with a double bit without such an inside collar.
  • 3 of the total of 4 key arms formed in a second key arm tool level comprise further drive profiles opposite the first key arm tool level of the respective key arm.
  • the first key arm tool level two square profiles arranged at an angle to each other with a rotational offset, one of which extends into the second key arm tool level or is only fully formed in this second key arm tool level.
  • Another design of a key arm provides that a triangular drive profile is formed in the first key arm tool level and offset to this in the first key arm tool level and also rotated to this, another square drive profile that in the first key arm tool level only with the anticipation surfaces is designed and then as a full profile in the inwardly offset second key arm tool level.
  • the drive profiles are preferably designed as closed profiles, although this need not necessarily be the case.
  • the key arms are expediently arranged in one plane and thus form a key plane.
  • the switch cabinet key can also include an adapter piece for receiving an insert tool, which can preferably be attached to at least one of the tool heads.
  • the insertion tool is preferably attached with an anti-loss device, which is particularly preferably designed as a chain.
  • This chain is preferably attached to a fastening part that is formed laterally on the central base body and between two key arms.
  • the insertion tool can comprise a screwing tool, which preferably has different screw drives at opposite ends.
  • the base body can also have a square receptacle with which a vent valve of a radiator can be opened and closed.
  • a tool head has a pyramid-shaped plug-in element which can be attached to square openings of different sizes.
  • the switchgear cabinet key can also be operated particularly well in confined spaces and with a small design if at least one key arm has a key surface for an open-end wrench or the like on the outside of the key arm. This can be done, for example, by flattening the front and back of at least one key arm, but it can also include an outside square or hexagon on the key arm.
  • connection In the context of this description, the terms “connected”, “connected” and “integrated” are used to describe both a direct and an indirect connection, a direct or indirect connection and a direct or indirect integration.
  • identical or similar elements are provided with identical reference symbols, insofar as this is appropriate.
  • FIG. 9 to 12 comprise sequences of figures each with four individual representations A to D to illustrate the specific design of the respective tool heads.
  • FIG. A shows an enlarged plan view
  • FIG. B shows a cross section of the front view according to FIG. A
  • FIG. C shows a cross section of the top view, i.e. at right angles to the plane defined by the front view according to FIG respective tool head.
  • the switch cabinet key 1 consists of a central base body 2 with four radially protruding key arms, namely a first key arm 3 with a first tool head 31 designed as a double bit, a second key arm 4 with a second tool head 41 comprising a square / square double tool, a third Key arm 5 with a third tool head 51 comprising a square / triangular double tool and a fourth key arm 6 with a fourth tool head 61 comprising a triangular / triangular double tool, which together form a key cross.
  • the central base body 2 comprises two additional tool heads 21, 22. This is oriented approximately perpendicular to the radial key arms 3, 4, 5 and 6.
  • the key arms 3, 4, 5 and 6 define a main key plane.
  • this tool head On the On one side of the base body 2, this tool head is designed with a square socket 21 and on the opposite side with a hexagon socket 22.
  • a fastening part 8 is provided for securing against loss.
  • the fastening part 8 is designed as a tab with an opening 81.
  • a closed, ring-shaped chain, not shown, can be provided as a safeguard against loss.
  • An insertion tool and an adapter piece are then suspended from the chain, which can preferably be designed as an insertion tool or as a screwing tool in the form of a so-called bit.
  • the first tool head 31 is designed as a double bit, which comprises a cylindrical base body 311, the outer surface of which encloses the key arm longitudinal axis running through the center of the key arm.
  • a cylindrical base body 311 In one piece formed on this cylindrical base body 311, two beards 312, 313 protrude radially opposite to the outside.
  • this is formed with a circumferential stabilizing flange 314, which the beards 312, 313 additionally stabilized and the notch effect on the beards 312, 313 of the cylindrical base body 311 is considerably reduced.
  • the beards 312, 313 are preferably designed in such a way that the beard flanks 3122, 3123 widen conically from the outer beard surface 3124 to the cylindrical base body 311, this widening increasing particularly strongly in the area of the base body 311, so that this widening provides an enlarged area for the Provides edge engagement (see in particular Figure 15 ).
  • the second tool head 41 is designed as a "square / square". This comprises a first drive profile designed as a first square 411 arranged in the primary, distal key arm tool plane and proximal of this primary key arm tool plane in the secondary key arm tool plane, a second drive profile designed as a second square 412.
  • the second square 412 is arranged collinearly with the first square 411, but smaller than the first square 411 and rotated by about 45 degrees relative to it about the longitudinal axis of the key arm.
  • a hexagon socket 413 is provided in this second tool head 41 collinear to the first square 411 and the second square 412, and proximal to the latter in a tertiary key arm tool surface, which in turn is smaller than the second square 412 and insofar is framed or enclosed by it .
  • the first square 411 in the primary i.e. distal key arm tool plane, which extends from the distal outer edge to the end of this square key surface, is about 6 mm deep
  • the second square 412 which is coaxial with the primary key arm tool surface, is approximately 6 mm deep Proximal to the first and 45 degrees rotated about the key arm longitudinal axis at a depth of approx. 3 to 5 mm following the primary key arm tool level, but the four edges or corners of the second square 412 extend into the first key arm tool level and there form the pre-engagement surfaces according to the invention, which, however, are provided in this way on each tool head.
  • the third tool head 51 is designed as a double wrench head and includes the combination of a triangular and a square drive profile (triangle / square).
  • the larger, triangular drive profile 511 is again arranged in the primary tool wrench plane collinear to the longitudinal axis of the key arm of the third key arm 5.
  • the fourth tool head 61 is also designed as a double wrench head (triangular / triangular), with a first triangular 611 in the primary, i.e. distal, key arm tool plane, and a second triangular 612 that is proximal to the first triangular 611 and smaller than it.
  • the first triangular 611 and the second triangular 612 are arranged collinearly along the longitudinal axis of the key arm, but are oriented rotatably offset from one another at an angle of approximately 60 degrees.
  • the second triangle 612 is approximately twice as deep as the first triangle 611 and smaller than the first triangle 611.
  • a hexagon socket 613 is provided in a tertiary key arm tool level proximal to the secondary key arm tool level.
  • each tool head is designed so that it comprises at least two drive profiles (key heads), of which one drive profile is arranged in the distal primary key arm tool plane and a second drive profile is arranged in the secondary key arm tool plane located proximally thereof, the second drive profile in the secondary key arm tool plane is made smaller in each case than the drive profile in the primary key arm tool level, preferably one key size smaller.
  • the second drive profiles / key surfaces preferably extend at least with the edges or corners into the first key arm tool plane and provide the pre-engagement surfaces according to the invention for the edge engagement there.
  • a third or fourth drive profile can be formed in each tool head, which is then preferably arranged in a respective tertiary key arm tool level proximal to the respective secondary key arm tool level in the key arm, and this tertiary key arm tool level is in turn made smaller than the respective second drive profile in the respective secondary key arm tool level.
  • the front and the back of the key arms 3, 4, 5, 6 of the switch cabinet key are flattened and thus define a key area for an open-end wrench, so that each key arm can be used even in confined spaces and with a small switch cabinet key of e.g. 65 or 55 mm total length from a proximal key surface outer edge to the opposite proximal key surface outer edge can apply sufficient force for the rotation or closure.
  • the outer circumferential surfaces of the key arms 3, 4, 5, 6 can naturally also have other geometrical outer surfaces to achieve the same effect, as long as this offers a sufficient force application surface for a tool wrench.
  • the inventive concept of the axial offset of two or more drive profiles along a key arm longitudinal axis in a key arm, the proximal second drive profile at least with the edges / corners from the proximal to the distal key arm tool plane to provide the pre-engagement surfaces for the edge engagement extends can also be implemented alone, that is to say on a tool which only comprises one such tool.
  • inventive double bit with the stabilizing flange and / or the radially inwardly widening bit flanks is not designed in combination with other tool heads on a switch cabinet key, but can also be designed as a separate, i.e. individual tool.
