Definitions

  • an adjustable support for acoustic enclosure constituted by two symmetrical elements, characterized in that each element comprises a base on which is fixed obliquely to the horizontal plane and located from bottom to top, from back to front, a support side formed by an L-shaped angle profile, folded square, and suitable for accommodating the base of the enclosure which is thus retained vertically and laterally, these two elements being assembled to one another by at least one telescopic crosspiece capable of being locked in the axial position corresponding to the width of the base. cited above.
  • the support shown in fig. 1 comprises two symmetrical elements A and B, assembled to one another by two adjustable crosspieces C arranged in superposition.
  • Each element A or B comprises an upright 1, advantageously established in tubular form.
  • the lower end of this upright 1 is provided with a horizontal base or base 2.
  • the assembly 1-2 forms a base for a support 3 constituted by an angle iron whose vertical wing faces outward; each angle 3 is folded back to the square and it will be observed that the lower part of this square is fixed to the top of the upright 1, not horizontally, but with a slight obliquity, oriented from bottom to top of the rear forward.
  • Each of the two superimposed cross members C comprises a horizontal section 4 which extends transversely in overhang from the lateral face of the upright 1.
  • each profile or end piece 4 is fitted, in the vicinity of its free end, with a pressure screw 5 which, as illustrated in FIG. 2, is engaged through a thread formed in a puncture in the wall of said nozzle.
  • Each cross member C is completed by an intermediate spacer 6, slidably introduced into the end pieces 5 facing the two elements A and B, and it is understood that the operation of the screws 5 allows this spacer 6 to be immobilized any desired axial position, the two elements A and B then being rigidly maintained at an appropriate spacing.
  • the two spacers 6 have a tab 6a folded transversely in the corresponding outlet, so as to form a stop for the end of the screws 5. This arrangement avoids that , when adjusting the useful length of each telescopic cross member C, the spacer 6 emerges inadvertently from one or the other of the two end pieces 4 which enclose it.
  • the user begins by loosening the four pressure screws 5, in order to release the spacers 6 from the crosspieces C. He places the enclosure on the ground with its base facing up, and, as illustrated in fig. 3, it has against this base D the support with the feet 2 also arranged upwards; the two elements A and B are then brought towards each other until the angles or supports 3 come to bear against the horizontal edges corresponding to the rear of the base D. At this moment it suffices to maneuver the screws 5 to immobilize the elements A and B in the position obtained, and turn the enclosure over with the support to rest it on the ground.
  • angles 3 provide effective lateral retention of the acoustic enclosure, at the same time as they support the latter at the height and at the obliquity deemed to be the most favorable.
  • the adjustment of the support is carried out very simply, the operation being capable of being carried out by the user himself, without requiring neither particular skill, nor tool.
  • each cross member C In some cases it is possible to dispense with intermediate spacers 6, one of the end pieces 4 of each cross member C then being dimensioned to be telescopically inserted into the outlet of the opposite end piece.
  • the number of crosspieces C can be any; in the same way, the base 1-2 of each element of the support can be shaped in any suitable way.
