Definitions

  • the invention relates to the handling of suspended decorations or the like, in particular decorations, lighting projectors, sound equipment, and other accessories, provided in halls intended for performances (theaters or concert halls for example).
  • a device comprising a geared motor and a large drum attached thereto, and whose axis is perpendicular to the vertical plane passing through the support bar. Cables wound on this common drum pass over pulleys, before being hung on the carrier bar vertically from these pulleys.
  • Such a direct draft system has the drawback of being extremely bulky (in the direction of the axis of the drum), which is very inconvenient when several devices have to be placed side by side to handle a plurality of hanging decorations.
  • a counterweight roller chain device has also been proposed, the chain passing over a pinion wedged on the output shaft of a geared motor, and on other pinions with fixed axis for connection to a vertically movable lateral counterweight. Cables fixed at the top of the counterweight pass over respective pulleys overhanging said counterweight, then over pulleys which are vertical to the attachment points of the support bar.
  • Such a system is compact and safe, but it involves providing an expensive infrastructure, in particular a counterweight chimney which is necessarily made to measure.
  • a device with a propeller shaft overhanging the carrier bar has also been proposed, on which are fixed several threaded drums from which cables are directly unwound vertically to the respective attachment points on the carrier bar (see for example FR-A- 2,481,607).
  • the disadvantage of such a system with several threaded drums is that the carrier bar is moved laterally as soon as its height is changed (on one side or the other depending on whether the cables are unwound or wound).
  • it has been proposed to replace the cables with straps, the drums then no longer being threaded, which effectively eliminates the lateral displacement of the support bar during a change of height see for example DE-A -27 22 143).
  • each strap is wound flat on itself, so that the diameter gradually increases during winding, resulting in a loss of torque and an increase in speed.
  • the (variable) winding diameter of the straps can vary from one drum to another (due to variations in tension resulting from the load applied to each strap), which frequently results in a defect of -lead of the carrying bar at the end of the maneuver.
  • Another device has been proposed with a gear motor and drum with an axis perpendicular to the vertical plane passing through the support bar, but with a common tractor cable wound on the drum, extending horizontally. up to its end which is fixed to a block for connection to the hanging cables passing over respective pulleys.
  • the drawback of such a device is that it has to organize the guiding of the horizontal section of the towing cable.
  • variations in the height of the carrying bar are de facto limited by the available horizontal travel of the towing cable.
  • the invention aims to design a handling device which does not have the aforementioned drawbacks and limitations.
  • the object of the invention is therefore to provide a motorized device for handling hanging decorations or the like which is both compact, flexible and safe, with the possibility of having couples. high and constant, while being simple in structure and of reasonable manufacturing cost.
  • the beam is braced and braced, and its length is slightly greater than that of the support bar.
  • the motor-reducer assembly is an electrically operated motor-brake reducer with incorporated torque limiter, this motor-brake reducer being housed in the central space of the beam so as to be integrated into the volume of that -this.
  • the transmission shaft is coupled directly to the end of the output shaft of the brake gear motor.
  • each attachment means comprises a housing in which pivots the associated chain nut, said housing being fixed to the beam, preferably being suspended inside the latter.
  • the housing is made of two complementary half-shells whose joint plane coincides with the vertical plane of symmetry of the chain nut.
  • the housing is suspended from the beam by a central plate arranged at the joint plane, and the fixing of this central plate is of the pendulum type, with a movement in the direction of the transmission shaft.
  • the housing is suspended by means of elastic means, from a stirrup secured to the beam and to which is also suspended a central sheet arranged at the joint plane.
  • the two half-shells forming the housing define a lower bearing edge with which cooperates one or the other of two chain stops serving to delimit the range of variation of the lifting height of the carrying bar .
  • the housing or the central sheet associated with it carries two sensors with which cooperates, directly or by means of a bending plate integral with said housing, one or the other of two chain stops serving to delimit the range of variation of the lifting height of the carrying bar.
  • the two half-shells forming the housing prefferably support a casing on which the chain receptacle is hung.
  • the casing is supported by a lower edge on a horizontal member of the beam.
  • the drive shaft is interrupted at each case, the coupling link between the adjacent sections being provided by a splined shaft passing through the housing, the associated chain nut being threaded directly onto this splined shaft.
  • the beam is produced in the form of sections placed end to end, including a first section incorporating the geared motor unit and a first housing, and at least one additional section incorporating one or two housings.
  • the beam is itself suspended by rollers or rollers on rails which extend perpendicular to the main direction of said beam, so as to be able to move the decoration or material suspended perpendicularly to his plan.
  • FIG. 1 illustrates a motorized device 1 in accordance with the invention, allowing the handling of hanging decorations or the like hung on a horizontal support bar 50.
  • a decoration 51 is illustrated in dashed lines, hung by rings 52 on the support bar 50.
  • sets it is understood that the invention does not only apply to hanging sets in theaters or concert halls, but also applies to projectors lighting, sound equipment, and other accessories provided in performance halls.
  • the motorized device 1 firstly comprises a three-dimensional and self-supporting horizontal beam 2, which delimits over its entire useful length a central space 6.
  • the beam 2 is formed by horizontal members 3, which are connected between them by bars 4 and 5 ensuring bracing and bracing of this beam.
  • the three-dimensional beam 2 here has a substantially rectangular section, but it goes without saying that a different shape can be chosen, for example a triangular section defined by three horizontal members.
  • the three-dimensional and self-supporting beam 2 can be made of steel if one seeks above all a high rigidity, in order to be able to handle decorations of significant weight, or aluminum if one seeks above all to have a device light and transportable.
  • the motorized device 1 further comprises a geared motor assembly 8 mounted at one end of the beam, and the output shaft of which is coupled to a transmission shaft 18 extending horizontally in the central space 6 of the three-dimensional beam 2.
  • the motor-reducer assembly 8 will preferably be an electrically operated motor-brake reducer with incorporated torque limiter.
  • a total integration of the geared motor assembly 8 is shown in the volume of the beam 2, that is to say that this geared motor is entirely housed in the central space 6 of said beam, which considerably reduces the overall dimensions and facilitates installation.
  • the geared motor assembly 8 will for example be bolted to a spacer plate 7 welded to the members 3 and it will be connected by cables such as the cable 10 to an associated control block 9 arranged at the end of the three-dimensional beam 2, said block being for example fixed on a spacer plate 11.
  • a remote control means connected to this control unit 9, in the form of a control box 12 mounted at the end of a cable of connection 13, and comprising two buttons 14 and 15 respectively making it possible to control the raising or lowering of the carrier bar 50 by rotating the output shaft of the brake gear motor, and the transmission shaft which is coupled to it, one way or the other.
  • the carrier bar 5O is suspended by chains 21, the lower end of which is fixed to this bar by means of an associated swivel 22. These chain sections 21 are naturally driven by the transmission shaft 18, as will be explained in more detail below, with reference to Figures 2 to 4.
  • FIG. 2 we find the three-dimensional and self-supporting beam 2 previously described, and we can see, at the end of this beam which is opposite to that receiving the brake gear motor 8, an end spacer plate 19 fixed to the four members 3.
  • FIG. 2 there is a distinction between the output shaft 16 of the brake gear motor with incorporated torque limiter 8, and the shaft transmission 18 is here directly coupled to the end of this output shaft 16 by means of a coupling 17 of conventional type.
  • a coupling 17 of conventional type Such a direct end coupling mode offers the advantage of direct transmission of the engine torque, without passing through intermediate pinions, and gives a very satisfactory robustness.
  • the motorized device 1 comprises a succession of attachment means 2O serving to suspend the carrier bar 5O while being able to vary the height thereof.
  • each hooking means 2O consists of a chain nut mounted coaxially on the transmission shaft 18 and rotated by it, and of a chain section 21 passing over this chain nut, said section being formed, whatever the height of the carrier bar 50, of a vertical strand whose free end is hooked on the carrier bar and of a dead strand received in an associated receptacle 24.
  • the transmission shaft 18 may be in one piece over the entire length of the three-dimensional beam 2, or alternatively, as has been shown here, produced in a plurality of successive sections which are connected together at the level of housings 23 which are fixed to the beam 2, preferably being suspended inside the latter.
  • Such an embodiment confers great flexibility, insofar as it is possible to adapt the length of the beam to the environment concerned, or even to transform the length of this beam when it is desired to dismantle the device for the '' set up in another room. Indeed, it suffices for example to disassemble a section of the beam and the corresponding section of the drive shaft, which immediately makes it possible to reduce the length of the beam accordingly.
  • the length of the beam will be slightly greater than that of the carrier bar 50.
  • this proximity sensor (for example of the inductive type) making it possible to detect the presence of the swivel of the chain , or as a variant of an end of travel stop mounted on the chain above this swivel, when the carrier bar is raised to the maximum desired height.
  • This proximity sensor is naturally connected directly to the power supply of the gear motor 8. It should be noted that if the initial travel is exceeded or if this proximity sensor malfunctions, the motorized assembly will slip. thanks to the torque limiter incorporated in the brake gear motor 8.
  • Another chain stopper mounted on the other chain strand (which is received in the aforementioned receptacle) will also be provided, this second stop being used to limit the low level of the suspended bar, by cooperation either with the lower edge of the associated housing 23, or with an associated proximity sensor.
  • this second stop being used to limit the low level of the suspended bar, by cooperation either with the lower edge of the associated housing 23, or with an associated proximity sensor.
  • provision will also preferably be made for chain stops, but the function provided by these stops will then be to prevent the chain from accidentally escaping during installation of the device.
  • the transmission shaft 18 is interrupted at the level of the housing 23, the coupling connection between the adjacent sections being ensured by a splined shaft 28 passing through this housing, splined shaft, the two ends of which are received in splined shaft end pieces 27 mounted at the end of the adjacent sections of the transmission shaft 18.
  • a splined shaft 28 passing through this housing, splined shaft, the two ends of which are received in splined shaft end pieces 27 mounted at the end of the adjacent sections of the transmission shaft 18.
  • the associated chain nut, denoted 29 which rotates at the inside of the housing 23 thanks to the presence of associated ball bearings 30.
  • the housing 23 is fixed to the beam 2, preferably being suspended inside the latter so as to preserve the integration of the components in the interior volume of the three-dimensional beam.
  • the housing 23 is produced in two complementary half-shells 23.1, 23.2, the joint plane Z of which coincides with the vertical plane of symmetry of the chain nut 29, said housing being suspended from the beam 2 by a central plate 31 precisely arranged at this joint plane.
  • the sheet metal 31 is thus clamped between the two complementary half-shells 23.1, 23.2, which are bolted together, the projecting part of the central sheet metal 31 then serving to secure the three-dimensional beam 2 on the spacer (s) concerned.
  • a fixing is shown produced by tightening the central sheet 31 between two spacers 4 connected by associated bolts 32, with the interposition of elastic washers 33.
  • Such an arrangement is particularly advantageous in this case, because it allows to define a suspension of the pendulum type housing 23, with a clearance in the direction of the transmission shaft 18 denoted X.
  • This pendulum type suspension of each of the housings 23 allows self-alignment of the different sections of transmission shaft .
  • the chain nut 29 is perfectly protected inside its housing 23, and, as can be seen more clearly in FIG. 4, this housing has two vertical passages 34, of cruciform cross section, for the passage of the two strands of the chain section concerned.
  • this housing has two vertical passages 34, of cruciform cross section, for the passage of the two strands of the chain section concerned.
  • FIG. 4 a clear distinction is made between the chain section 21 passing over the chain nut 29, which section is formed, whatever the height of the load-bearing bar 50, of a vertical strand 21.1 whose free end is hooked on the carrier bar 5O by the swivel 22, and a dead strand 21.2 which is received in an associated receptacle 24 fixed to the beam 2.
  • the attachment to the carrier bar 5O is ensured by the sockets 53 vertically passing through this bar, and welded thereto, through which passes the threaded rod 55 of a bolt, tightened by nuts 54, and the head of which is received inside the swivel 22.
  • the receptacle of chain 24 is for example fixed by a metal strip 37 to the beam 2, and it will be made of a flexible material, for example resistant plasticized canvas. In this way, when the carrier bar is raised, the dead strand 21.2 of each chain section 21 is gradually received in its associated receptacle 24.

  • the three-dimensional and self-supporting beam 2 is first of all both compact, and the integration of the various components of the motorized device, and in in particular, the brake gear motor with incorporated torque limiter does not interfere with the overall compactness.

  • provision may be made to arrange the assembly motor-reducer at another location in the U, T, or L structure, rather than at the end of the horizontal beam from which the carrier bar is suspended.
  • angle references it will suffice to use angle references to transmit the rotational movement to the transmission shaft extending horizontally in the central space of the three-dimensional self-supporting beam 2.
  • This chain suspension is also advantageous insofar as it suffices to change the length of the chain sections to adapt to a different suspension height of the support bar. It should then be noted that, whatever the lifting height of the support bar, the section of the beam remains the same.
  • the chain sections being in any case of the same length, these chains do not cause any difference in level of the load-bearing bar, and whatever the height thereof, which permanently guarantees perfect horizontality of this load-bearing bar .
  • the chain sections can completely disappear in the sleeves of a false ceiling. It is also possible to direct one or more sections of chains in a receptacle, for use of a single section of chain of the device, which allows for example to adapt the device of the invention to the lifting of a particular assembly such than a chandelier.
  • the arrangement of the three-dimensional, self-supporting beam, with its internal drive shaft made up of several sections placed end to end, makes it possible to obtain a variable length, which gives great flexibility. of installation.
  • the rigidity conferred by the three-dimensional and self-supporting beam considerably reduces the number of suspensions for fixing in the hangers or frames of the room, and avoids the establishment of expensive and bulky primary structures.
