Definitions

  • the invention relates to a fastening device for constructing an arrangement of a plurality of mutually suspended loudspeaker boxes, an arrangement of a plurality of mutually suspended loudspeaker boxes and method for constructing an arrangement of a plurality of mutually suspended loudspeaker boxes.
  • FIG. 1 A typical prior art line array 1 is shown in FIG.
  • the line array 1 is composed of a plurality of speaker systems or boxes 2, the housing are hung on housing at a precisely defined intermediate angle each other. The entire assembly is suspended on a so-called flying frame 5 and aligned.
  • the vertical profile of the resulting wavefront - determined by the angles between the individual loudspeakers 2 - specifies the sound level distribution in the listener area.
  • connecting elements between the individual housings are provided, which on the one hand ensure a secure cohesion of the individual housing in the high loads occurring and on the other hand must allow the variability of the intermediate angle adjustment.
  • attachment systems for line arrays 1 should be inexpensive and must meet high safety requirements, in particular, the risk of accidents during assembly and disassembly must be kept as low as possible.
  • the housings or loudspeaker boxes 2 are provided in the front area by articulated connection elements 3, e.g. an anchored in a speaker housing pivot and an anchored in the other speaker housing, the pivot receiving female perforated plate - interconnected.
  • the hinged connecting elements each define the axis of rotation between a pair of speakers.
  • the setting of the intermediate angle is usually carried out in the rear of the speakers 2.
  • the speakers 2 are equipped there with side-mounted perforated plates 4. To fix the speakers 2 below the desired intermediate angle to each other, the speakers 2 must be aligned with each other and set by inserting a locking bolt through a suitable pair of holes two perforated plates 4 in their relative position to each other.
  • a disadvantage of this system is that assembly and disassembly are expensive. An assembly / disassembly on a hanging system is difficult and accident-prone, since the insertion or removal of the locking pin under load (weight of the speakers) must be made. In addition, there is not the possibility of preselection of an intermediate angle in the not yet fixed state during assembly.
  • the rear connecting element 4 is realized in the form of an adjustable stop.
  • the intermediate angle can be preselected before the loudspeaker boxes 2 are hung or pulled up against each other at their front articulated connecting elements 3.
  • the loudspeaker boxes 2 After the loudspeaker boxes 2 are connected in the front region via the articulated connection elements 3, they hang down in a straight line (the intermediate angle is 0 °).
  • the curvature of the line array 1 now takes place via a Belt, which is attached to the lowest speaker box 2 and at the back of the line array 1 upwards (eg to the flying frame 5 back) out. By tightening this belt, the line array 1 is bent so far until the end position is reached by the action of the attacks between the speakers 2.
  • Another known fastening system also uses a stop for the rear connecting elements 4, which however-unlike the above-described system-defines the minimum possible intermediate angle (the maximum possible intermediate angle is predetermined by the trapezoidal cross-section of the housing 2).
  • This system has the disadvantage that it can typically only be used with relatively short line arrays 1, since with long line arrays 1 and / or high curvature (not only tensile forces, but also) shear forces occur in the region of the rear connecting elements 4 can, for which such an angle stop is ineffective.
  • the invention has for its object to provide a fastening device for constructing an arrangement of a plurality of mutually suspended speakers, which allows a simple, time-saving and at the same time secure assembly / disassembly of the device (e.g., line array). Furthermore, the invention aims to provide methods for constructing an arrangement of a plurality of mutually suspended loudspeaker boxes, which meet the above requirements.
  • the fastening device according to the invention for the construction of the arrangement of mutually suspended loudspeaker boxes comprises a latching connection, with which two in the arrangement adjacent loudspeaker boxes are fauxsch.
  • the particular advantage of the latching connection is that the connection is formed automatically as a result of the latching.
  • the connection can therefore be realized both under load (that is to say when mounting loudspeaker boxes to an already suspended system) and without load, without difficulty. This reduces the assembly time, allows different installation procedures and reduces the risk of accidents during assembly / disassembly.
  • the latching connection is designed so that the two adjacent speakers in the arrangement areraitschschreibbar at a presettable angle. This allows the preselection of a desired angular position, in which the latching engagement is formed automatically.
  • the latching connection comprises a latching hook mounted on a loudspeaker box and a holding element mounted on another loudspeaker box and cooperating with the latching hook.
  • the fastening device preferably has a profiled part provided with a perforated grid, wherein the retaining element is a locking pin which can be inserted into holes of the perforated grid.
  • the latching hook is pivotally mounted on the profile part, whereby the profile part serves both for fastening of the holding element and for fastening the latching hook.
  • a further advantageous embodiment of the invention is characterized in that the latching connection in the locked Condition by means of a mechanical securing element against loosening from the detent position is securable.
  • the mechanical securing element can be achieved that the locking connection can also absorb shear forces (which act in the direction of increasing intermediate angle), whereby the dimensionability of the arrangement is extended from one another arranged hanging loudspeaker boxes.
  • the securing element can be realized in the form of a securing bolt, which can be inserted into a securing hole provided in the hook area of the latching hook and cooperates with holes in the perforated grid of the profile part.
  • loudspeaker box for loudspeaker box are attached to the already suspended, partially constructed arrangement of a plurality of mutually suspended loudspeaker boxes.
  • the method is characterized by the steps that one (each) speaker box, e.g. is attached at its front area to the currently lowest speaker of the partially assembled arrangement (or the uppermost speaker to the flying frame), and that the attached speaker is then raised at its rear area until the latching connection engages. In this way, a simple floating mounting of such an arrangement without additional aids, such as straps, etc., are performed.
  • the method is characterized by the steps of stacking the preassembled loudspeaker boxes of a group, the articulated connecting them eg in their front area, the hanging of the top speaker of the preassembled stack (ie the group) of speakers eg at its front on a flying frame or on the lowest speaker of the partially assembled arrangement, the forming the latching connection between the flying frame or the lowermost speaker of the partially assembled arrangement and the uppermost speaker of the stack of loudspeakers and forming the latching connections within the stack of loudspeakers.
  • This variant of the method benefits from the automatic forming of the latching connections between the loudspeaker boxes of the stack when pulling up or lifting the preassembled group of loudspeaker boxes.
  • loudspeaker boxes 2 according to FIGS. 2 and 3 are suspended on a flying frame 5 according to the linear arrangement shown in FIG. 1 (line array consisting of a row of loudspeaker boxes 2 suspended from one another).
  • line array consisting of a row of loudspeaker boxes 2 suspended from one another.
  • two parallel steel sheet strips 30 are provided on both side edges of a loudspeaker box 2, which extend laterally adjacent to the front side (radiation area 31) of the loudspeaker box 2 over the height dimension of the loudspeaker box 2.
  • the steel strip pairs 30 each hold a housing side wall 36 of the speaker 2 and are firmly connected thereto.
  • the StahlblechstMailcrucrue 30 have, as seen in Fig. 7, at their ends mounting holes 32.
  • a tab 33 may be mounted with a bearing eye 34.
  • the tab 33 with the bearing eye 34 is above the top of the speaker 2 via.
  • the two tabs 33 of the lower speaker are brought to the lower end of the sheet steel strip 30 of the overlying speaker 2 and there is a respective Lagerbolzen35 through the bearing eye 34 on the sheet steel strip pair 30 of the lower speaker 2 and the mounting holes 32 in StahlblechstMailcrufar 30 of the upper speaker 2 plugged.
  • This connection in the front area defines the pivot axis between the two speakers 2.
  • the front connection between the flying frame 5 and the top speaker 2 is carried out in a corresponding manner.
  • connection mechanisms are used, which allow a pivoting of the speakers 2 relative to each other.
  • pairs of sheet steel strips 30 also mounted on the housing of the speaker box 2 square tubes or U-profiles can be used, in which then inserted a hinge element with two connected via a hinge attachment legs in opposing square tubes or U-profiles or inserted and locking pins on both sides his attachment legs is locked.
  • the axis of rotation is not realized by the locking pin, but by the joint in the joint element.
  • each loudspeaker box 2 has on its rear side a high-strength profile 20 with a wide base plate 21 and a double web 22.
  • the base plate 21 is firmly anchored to the rear wall 29 of the speaker 2.
  • the double web 22 forms the legs of a U and is formed in the upper region in the manner of a double-hole grid 23. Furthermore, there are two opposite bearing holes 24 in the lower region of the double web 22nd
  • the bearing holes 24 serve for the pivotable mounting of a latching hook 25 (not shown in FIG. 5).
  • the latching hook 25 can be pivoted according to the arrow P in Fig. 4 by about 180 °.
  • a transport position see Fig. 3, lower speaker 2
  • the latching hook 25 In its downwardly pivoted detent position (see FIG. 4), the latching hook 25 projects beyond the underside of the loudspeaker box 2.
  • the latching hook 25 engages in its latched position a locking pin 26, which was previously by a pair of holes in the double-hole grid 23 of the double web 22 of a speaker 2, which is located under the latch hook 25 carrying speaker 2 is inserted.
  • a securing bolt 27 is provided, which by another hole pair in the Double hole grid 23 and a hole 28 provided for this purpose in the remote storage hook area of the latching hook 25 is pushed and locked the locking connection securely.
  • the securing bolt 27 is also achieved that the latching connection can absorb and forward not only tensile forces, but also (high) shear forces.
  • the double-hole grid 23 may have, for example, two or more rows of holes, wherein the spacing between the holes is chosen so that on the one hand the required stability of the profile 20 can be guaranteed and on the other hand a sufficiently fine Winkelein suitkeit is made possible. It can optionally holes of the outer or inner row of holes of the double hole grid 23 for the locking pin 26 and the locking pin 27 are used.
  • the latching hook 25 may be executed in this case, for example, with a longitudinal slot for the single web.
  • the latching hook 25 is preferably locked via a locking pin in its transport position.
  • the hole for the locking pin is indicated in Fig. 4 by the reference numeral 40. This ensures that the snap hook 25 is not damaged during transport or can cause damage / injury.
  • the securing pin is removed and the latching hook 25 is folded out of its transport position.
  • the latching hook 25 falls due to gravity against a provided on the profile 20 of the upper speaker 2 stop (not shown), which causes the latching hook 25 in a defined position (see Fig. 3, upper speaker 2) rests.
  • the locking bolt 26 will follow the acting as a baffle frontal inclined surface portion 41 of the latching hook 25 and lifts the latching hook 25 while his seat.
  • the relative to the longitudinal extent of the latching hook 25 at an acute angle oriented inclined surface portion 41 may extend substantially over the entire end face of the latching hook 25. The latching then takes place due to gravity by falling back of the latching hook 25 on the locking pin 26 as soon as the desired intermediate angle is reached.
  • the latching hook 25 can also be biased by a spring mechanism (not shown) so that it remains on the one hand in its transport position and on the other hand - after a manual unfolding - in its unfolded rest position (see Fig. 3, upper speaker 2) against the stop (not shown), ie in the direction of the rear wall 29 of the speaker housing 2 of the lower speaker 2 is pressed.
  • the latching hook 25 is also secured during transport and beyond the bias secures the defined rest position of the latching hook 25 (and thus ensures the automatic engagement of the latching connection) even in the case of installation of the speaker 2 with a slightly upward radiation of the same.
  • FIG. 6 show the connection between the flying frame 5 and the uppermost speaker box 2.
  • the flying frame 5 has at its rear portion a latching hook 51, which may be identical to the latching hook 25.
  • this latching hook 51 just like the latching hook 25, is fastened to the double web 22 of the U-profile 20 by a locking bolt 26 and a securing bolt 27.
  • the latching connection according to the invention can be modified in many ways.
  • a latching hook another Verrastungsteil, eg a rack with side or front and / or Rear-mounted locking teeth and instead of the locking bolt 26 may be provided a displaceable locking pawl with a complementary trained teeth.
  • the preselectability of the angular position can be realized in this case, for example by an adjustable stop for the rack.
  • the latching connection does not necessarily have to be provided in the rear area of the loudspeaker boxes 2.
  • the individual loudspeakers 2 can be e.g. Weigh 60 kg.
  • the speaker boxes 2 can measure 110 cm x 36 cm x 58 cm (width x height x depth).
  • the flight frame 5 can be designed for a system load of 1.5 t with tenfold security.
  • the hole pattern 23 can be dimensioned so that an intermediate angle between the speakers 2 in the range of 0 ° to 7 ° can be set in 1 ° increments.
  • the trapezoidal cross-section of the loudspeaker boxes 2 can be dimensioned such that the upper and lower sides of adjacent loudspeaker boxes 2 enclose a housing angle of 7.5 ° at an intermediate angle of 0 ° (parallel radiation). All connecting elements 20, 21, 22, 23, 24, 25, 26, 27, 51 are dimensioned so that tensile and compressive loads of 20 kN per element are ensured with a safety factor of 5.
  • the line array 1 can carry more than 10, in particular more than 20 loudspeaker boxes 2.
  • loudspeaker box 2 for speaker 2 can be attached. This happens in the Way, that the speaker boxes 2 are first "pinned”, ie the locking pin 26 are inserted into the desired mounting holes of the double hole grid 23 in the double web 22.
  • the line array 1 is then constructed from top to bottom by successively attaching speakers 2. For this purpose, each speaker box 2 is first hung on the front (on sheet steel strip 30) and then raised back so far until the latch hook 25 automatically locks in the preselected angular position. Subsequently, the securing bolt 27 is inserted, whereby a rigid connection is formed on the back of the line array 1, which also has no problem with shear forces.
  • An alternative construction variant is to pre-assemble the loudspeaker boxes 2 in groups of suitable size on the floor (ie not in the suspended state) and then suspend the pre-assembled groups in succession.
  • the speakers 2 are pre-pinned in the manner already described.
  • four loudspeakers 2 each stacked on a cart or skateboard and connected to each other at the front, articulated connection elements 30, 33, 35. Since, for example, four loudspeaker boxes 2 of a group of housings overlap one another on the housing and thus result in a curved housing stack corresponding to the housing angle (eg 7.5 °), it is advantageous if the carriage / the roller board is wedge-shaped in order to counteract an inclination of the housing stack , The latch hook 25 is in its folded down position.
  • the preassembled group of speakers 2 is then attached to the front (to the steel strip pairs 30 of the top speaker 2) to the flying frame 5 and to the lowest speaker 2 of the partially constructed line array 1. If possible, the rear locking connection between the flying frame 5 and the lower speaker 2 of the semi-finished line array 1 and the top speaker 2 of the preassembled speaker group is now formed, for example by the flying frame 5 is slightly lowered. Subsequently, the flying frame 5 pulled up, whereby the latching connections realize one after the other within the speaker group.
  • An alternative possibility for generating the individual latching connections within the group of preassembled loudspeaker boxes 2 is that after attaching this group to the flying frame 5 or to the lowest loudspeaker box 2 of the partially constructed line array 1, each individual loudspeaker box 2 of the group starting with the uppermost Loudspeaker box 2 is raised slightly at its rear until the corresponding latching connection with the overlying speaker box 2 results. In this way, the speakers 2 of the group are successively fixed from top to bottom in the desired angular position on the line array 1. Subsequently, the securing bolts 27 are used in the manner already described.
