Definitions

  • the invention relates to a device for the adjustable fastening of a microphone boom according to the preamble of patent claim 1.
  • Such a device is known from DE-21 05 004-A1.
  • the only screwable locking means is designed as a clamping screw which projects laterally from the holder of the microphone boom and can be rotated about a horizontal axis, the actuation of which is not always felt to be optimal in terms of grip.
  • the device contains elastic tensioning elements in the form of tensioning springs and a slotted sleeve, which can tire, so that the functionality of the device can deteriorate over time.
  • Figure 1 is a diagrammatic overall view of a microphone boom with stand rod and stand base
  • FIG. 2 shows an enlarged, diagrammatic representation of a device for the adjustable fastening of the microphone boom at the upper end of the stand rod;
  • Figure 3 is a sectional view of the device of Figure 2 in the direction of arrows III-III in Figure 4;
  • Figure 4 is a sectional view taken along the line IV-IV in Figure 3;
  • FIG. 5 shows a perspective view of an inner tensioning bracket
  • FIG. 6 shows a diagrammatic view of an outer tensioning bracket
  • Figure 7 is a perspective view of a bar.
  • a height-adjustable tripod rod 3 consisting of two telescoping parts 1 and 2 is shown in a three-legged tripod base 4 in vertical tion attached.
  • the microphone boom 6 is designed as a rod which has a handle 20 at one end.
  • a microphone (not shown) can be attached to the end of the microphone boom 6 opposite the handle 20 in a manner known per se.
  • the device 5 comprises, as will be described below, a holder for the microphone boom 6, which makes it possible to adjust the inclination of the microphone boom 6 to the horizontal and to move the microphone boom in the device 5 along its axis. The respectively set inclination and displacement position of the microphone boom 6 can then be fixed with the aid of a single locking means to be described.
  • FIGS. 2, 3 and 4 show the device 5 for the adjustable fastening of the microphone boom 6 in detail.
  • a holder 7 of the device 5 comprises a first or inner clamping bracket 8, shown diagrammatically in FIG. 5, and a second or outer clamping bracket 9 shown in FIG. 6. Both clamping brackets 8, 9 have white bearing bushes 10, 11 which are penetrated by the microphone boom 6 and enclose it.
  • the outer clamping bracket 9 is movable relative to the inner clamping bracket 8 transversely to the longitudinal axis of the microphone boom 6, so that such a displacement of the microphone boom 6 can be clamped to the clamping brackets 8, 9.
  • a joint part 12 with an external thread is fixedly arranged at the upper end of the stand rod 3, for example glued on, soldered on or held by a grub screw.
  • a hinge pin 13 extending transversely to the longitudinal axis of the stand rod 3 is formed in one piece, which serves as a horizontal axis of rotation for the holder 7 and permits an inclination adjustment of the microphone boom 6 about this axis.
  • the inner clamping bracket 8 is rotatably supported on the hinge pin 13.
  • the inner clamping bracket 8 has two legs 14, 15 projecting downwards, on each of which a bearing recess 16 is formed which engages the pivot pin 13 from below.
  • the hinge pin 13 can be inserted laterally through a groove 17 (FIG. 3) formed on the legs 14, 15 and opening into the bearing recess 16 and brought into the bearing recess 16.
  • a latch 18 is rotatably arranged on the microphone boom 6, which is shown graphically in FIG.
  • This bolt 18 has a web 19 (directed downwards in FIGS. 3 and 4) which, as can be seen from FIGS. 3 and 4, lies with its lowest apex at a minimal distance above the hinge pin 13.
  • the inner clamping bracket 8 is rotatably fixed on the hinge pin 13. If the bolt 18 is turned into the position shown in dash-dotted lines in FIG. 4 (which can also be seen in FIG. 7), the inner clamping bracket can be detached from the hinge pin 13 through the groove 17.
  • the outer clamping bracket 9 has two (in the drawing facing downwards) bearing webs 21, 22 which are formed in the lower area facing the joint part 12 as circularly curved clamping surfaces 23 and run laterally past the joint part 12 or the joint bolt 13.
  • a clamping nut 24 provided with a corresponding internal thread, which nut can accordingly be moved up and down in the longitudinal direction of the stand rod 3 by rotation.
  • a pressure ring 26 is arranged, which, like the clamping nut 24, encloses the joint part 12 and is movable up and down when the clamping nut 24 is turned.
  • pressure surfaces 27 (FIG. 4) are formed, which can be brought into frictional engagement with the clamping surfaces 23 by appropriate displacement of the pressure ring 26, in order thus the bearings ⁇ webs 21, 22 and thus to lock the entire holder 7 in a certain inclination position.
  • the described device works in the following way: If - cf. 3 and 4 in particular - the clamping nut 24 on the joint part 12 is rotated correspondingly downwards, the pressure surfaces 27 of the pressure ring 26 detach from the clamping surfaces 23 on the legs 21, 22 of the outer clamping bracket 9. In this position the consisting of the inner clamping bracket 8, the outer clamping bracket 9 and the bolt 18, by the microphone boom 6 The holder 7 held can be pivoted freely about the hinge pin 13 which conveys a horizontal axis of rotation, the bolt 18, which is directed downward with its web 19, preventing the holder 7 from detaching from the joint part 12.
  • both clamping brackets 8, 9 continue to sit relatively loosely on the microphone boom 6, so that the microphone boom 6 is longitudinally displaceable in the bearing bushes 10, 11 of the clamping bracket 8 and 9, respectively.
  • the clamping nut 24 is after twisted at the top, so that the pressure surfaces 27 which are brought along by the pressure ring 26 come to rest against the circularly curved clamping surfaces 23 of the outer clamping bracket 9.
  • the set inclination position of the microphone boom 6 is fixed.

Abstract

Un dispositif de fixation réglable d'une perche de microphone comprend à l'extrémité supérieure d'une tige-support verticale, un support pouvant tourner autour d'un axe de rotation horizontal et dans lequel la perche de microphone peut se déplacer longitudinalement, ainsi que des moyens de fixation destinés à maintenir le support dans une position inclinée établie et à maintenir la perche de microphone dans une position de déplacement établie. En tournant un écrou de serrage, il est possible de faire monter et descendre un premier étrier de serrage par rapport à un second étrier de serrage, entre une première et une seconde position de manière à ce que dans la première position, les deux étriers de serrage puissent tourner autour de l'axe de rotation du support, par coulissement libre des surfaces de serrage du second étrier de serrage sur les surfaces de pression déplacées par l'étrier de serrage, afin d'ajuster l'inclinaison de la perche de microphone. Dans la première position, la perche peut être déplacée librement dans les étriers, alors que dans la seconde position de fixation de linclinaison établie de la perche de microphone, les surfaces de serrage appuient sur les surfaces de pression par friction et les deux étriers de serrage bloquent la perche de microphone, évitant ainsi que cette dernière ne se déplace longitudinalement.
