    DK 2008 00177 U4
    Adjusting spindle for a luminaire
    The invention relates to a securing device as described in the preamble of claim 1.
    GB 2 378 234 A discloses a preventive device for preventing unauthorized operation of an adjusting spindle, with a spindle adapter which can be attached to a cone pin of the adjusting spindle and a tool adapter which can be attached to the spindle adapter. The spindle adapter has a cylinder part which is concentric relative to a center axis and which a cylindrical eccentric pin protrudes at the end surface for application and operation with the tool adapter. An attachment portion of the tool adapter has a cylindrical inner recess that is inserted concentrically relative to the center axis, as well as an eccentric internal recess that can be engaged by the spindle adapter's eccentric pin. Furthermore, the tool adapter is provided with a cone pin which is located concentric to the longitudinal center axis and to which a standardized tool intended for immediate operation of the adjusting spindle can be mounted.
    The object of the invention is to provide a securing device in the form of an attachment to an adjusting spindle of a luminaire which effectively prevents unauthorized operation.
    This object of the invention is accomplished by the features set forth in the characterizing part of claim 1. The surprising advantage here is that by forming a core member and an attachment sheath which covers and surrounds it at the perimeter, and which is freely rotatable without the appropriate coupling means of an actuator, can prevent the actuation force of an adjusting spindle from being produced.
    2 DK 2008 00177 U4
    Designs, such as those described in claims 2 to 5, are also advantageous because by means of these it is not possible to operate the adjusting spindle with tools which do not have an interconnecting effect between the core part and the freely rotatable attachment sheath.
    5
    There is also the possibility of a design according to claim 6, in which it is possible to design the securing device to suit different operating forces dependent on the type of luminaire's design.
    10 According to the advantageous further developments described in claims 7 to 12, a very compact structural element for the attachment sheath is obtained and the manufacture and assembly are facilitated.
    By means of the advantageous further developments described in claims 13 and 14, it becomes easier to disassemble the securing attachment from the adjusting spindle's cone loss, especially for repair or maintenance work.
    The advantageous further development described in claim 15 allows for a low-cost serial production at a high manufacturing quality and strength to produce the necessary operating power.
    The advantageous further developments described in claims 16 to 19 are also advantageous because of a low production cost.
    Finally, a design according to claim 20 is also advantageous, whereby different material variants can be selected corresponding to the requirements of the operating means.
    For a better understanding of the invention, this will be explained in greater detail by means of the exemplary embodiments shown in the figures.
    3 DK 2008 00177 U4
    Here, FIG. 1 is a sectional view of the securing device according to the invention with a securing attachment and an operating means; FIG. 2 is a sectional view of the securing device according to the invention; FIG. 3 is a sectional view of the securing device taken along the lines III-III in FIG. 1; FIG. 4 is a sectional view of the securing device taken along lines IV-IV of FIG. First
    Initially, it is to be noted that the same parts are provided with the same reference numerals or the same structural sub-designations in the various described embodiments, since the submissions stated in the overall description can be sensibly transferred to the same parts with the same reference numerals or the same structural partial designations. Also, the indications of location selected in the description, such as e.g. above, below, next to, etc., to the immediately described and shown figure and, in a change of location, must be sensibly transferred to the new location.
    In FIG. Figures 1 to 4 show a securing device 1 with a securing attachment 2 and an operating means 4 which can be connected to the securing attachment 2 for adjusting movement of an adjusting spindle 3 to a locking fixture not shown further.
    In the illustrated embodiment, the fuse attachment 2 is formed in two parts, consisting of a cylindrical core part 5 and a tubular attachment cover 6. The attachment cover 6 is on one side completed with an end disc 4 which covers the core part 5 by a end face facing away from the adjusting spindle 3.
    The core portion 5 has concentric relative to a center axis 8 a tapered inner receptacle 9 for a taper pin 10 of the adjusting spindle 3. The taper pin 10 is generally a 4-edge pin on which the core portion 5 of the securing attachment 2 is held under pressure. Preferably, in the inner recess 9, a hexagon nut 11 is pressed with a thread 12 oriented concentrically with respect to the center axis 8. Thus, the core portion 5 can be loosened as needed after removing the end disk 7 from the taper pin 10 by means of a not further shown adjusting screw through a bore 13. For removal of the end disk 7, a breaking groove 14 is provided between the end disk 5 and a casing-shaped sheath portion 15 of the attachment sheath 6.
    The core portion 5 as well as the casing-shaped sheath portion 15 with the end disk 7, which covers an end surface 16 of the core portion 5, are preferably manufactured as an injection molded portion of plastic.
    The attachment sheath 6, together with the end disk 7 and the tubular sheath portion 15, surrounds the core part 5 and is secured to an extension on the core part 5 via a retaining ring 17 on an end region 18 opposite the end disk 7.
    The retaining ring 17 projects in a bead-like manner beyond an inner diameter 19 of the attachment sheath 6 in the direction of the center axis 8 and overlaps an annular surface 20 of the core member 5 such that a diameter 21 of a through-bore 22 in the retaining ring 17 is slightly smaller than an outer diameter 23 of the cover 6.
    The attachment sheath 6 is pivotally mounted on the core part 5 as a result of a clearance between the inner diameter 19 of the attachment sheath 6 and the outer diameter 23 of the core part 5.
    An internal distance 24 between the end disk 7 and the bead-shaped retaining ring 17 is slightly greater than a height 25 of the core portion 5.
    The attachment sheath 6 is mounted for mounting on the core part 5 by means of a compressive force in the axial direction, whereby the sheath part 15 with the 10 bead-shaped retaining ring 17 is extended by virtue of an elastic deformation. In the region of the end surface 16, the core member 5 has an inclination of the outer diameter 23, whereby respectively. the attachment process and the necessary elastic extension of the retaining ring 17 are facilitated. A resilience of the cap portion 15 then causes the end surface 20 of the core portion 5 to engage 15 and the attachment cap 6 to be securely secured axially.
    According to a possible further development, as shown with dashed lines, the attachment sheath 6 has, in extension of the tubular sheath portion 15, a neck ring formed in one, which serves, for example, to cover any possible connecting means, f. eg. a screw for securing a cone attachment.
    The core portion height 25 is greater than a length 26 of the cone pin 10 plus a nut height 27 and a cover height 28 having bore 13.
    25
    As can be seen more clearly in FIG. 2 to 4, in the core portion 5 of this exemplary embodiment, four slotted grooves 29 are provided which are distributed uniformly over a circumference and extend over the overall height 25 and are oriented parallel to the center axis 8 at a 90 ° pitch angle. These are formed by bores 31 arranged on a center circle 30 which extend concentrically with respect to the center axis 8 and which are opened by means of approximately parallel side surfaces 33 corresponding to a diameter 32 in the direction of the outside. circumference. These form coupling receptacles 34 in the core portion 5 for use of applying the actuating means 4 for a power transmission to the adjusting spindle 3.
    A center circle diameter 35 is slightly smaller than the outside diameter 23 of the core part 5 minus twice the diameter 32 of the bores 31 in the interconnection recesses 34.
    As further shown in FIG. 4, in about the same center circle 30 with the center circle diameter 35 and in a 90 ° angular pitch, four through bores 36 are also provided in the end disc 7 of the clamping cap 6 as additional connecting holes 37 with a diameter 38 approximately corresponding to the diameter 32 in the grooves. 29 bores 31.
    The operating means 4 are designed, as is further apparent in particular from FIG. 1, of a disc-shaped base portion 39 and, for example, also a cone pin 40, which is arranged concentrically with respect to the center axis 8.
    The base member 39 has coupling means 43 which project beyond an end face 41 which is opposed to the taper pin 40 and which is formed by cylinder pins 42, which are also located at the 90 ° pitch angle on the center circle 30 with the center circle diameter 35, and the center axes 44 are oriented in parallel. with the center axis 8.
    A diameter 45 of the cylinder pins 42 is slightly smaller than the diameter 38 of the through bores 36 in the end disk 7 and the bores 31 of the grooves 29.
    Cylinder pins 42 protrude beyond the end face 41 of disc-shaped base portion 39 and protrude after application of the interconnect application 42 on the end disc 7 through the through bores 36 and beyond a portion of the height 25 of the interconnect receptacles 34 of the core portion 5.
    This allows a form-fitting connection between the actuating means 4 and the core part 12, which is arranged on the taper spindle 10 of the adjusting spindle, thus making it possible to operate the adjusting spindle 3.
    When the operating means 4 are connected, i. however, when the coupling means 43 are engaged with the coupling apertures 34 of the core member 5 to adjust the adjusting spindle 3, however, positioning of the pivotal mounting sheath 6 is required to bring the coupling apertures 34, 37 of the core part 5 and the coupling cap 6 into a congruent level.
    Due to the pivotal position of the attachment sheath 6 on the core part 5 and its cylindrical smooth wall configuration as well as the location and configuration of the interconnecting recesses 34, 37 and the interconnecting means 43, it is virtually excluded that unjustified and harmful manipulation by unauthorized persons who do not possess the corresponding designed actuator 4 may take place.
    Of course, instead of the cone pin 40, other forms of a handle, e.g. a T-bar by means of which a pivotal movement can be exerted on the core portion 5 after the application of the operating means 4 to the securing application 2.
    In the illustrated embodiment, the coupling receptacles 34, 37 and the coupling means 43 at the circumference 30 with the circumferential diameter 35 according to a preferred embodiment are spaced apart at a center angle 46 of 90 °. Of course, there is also the possibility of another DK 2008 00177 U4 8 similar location, e.g. 45 °, 60 ° or 120 °, as well as an irregular angle distribution.
    Finally, for the sake of good order, it should be noted that, for a better understanding of the structure of the fuse, the fuse device and its components are not partially scaled and / or shown enlarged and / or diminished.
    The task on which the independent inventive solutions are based is apparent from the description.
