  • an opening 5 through which passes the playback deck 6.
  • Said deck 6 is made fast to a movable framing 7 the upper platen of which is provided with an opening 8 for the passage of the underly ing portion such as the motor, of the playback deck 6.
  • the movable framing is provided at each corner thereof, with a foot or extension 9, 10, ll and 12, respectively, which preferably slants outwards, said feet being preferably provided at the lower end thereof, with a groove 13.
  • Each foot 9 to 12 is made fast to a cable 14 by means of an adjusting device 15 for example, the other end of said cable being made fast to a second adjusting device 16 which is formed in this case by a guide-rod 17 which is movable inside a hole 18, 19, 20 and 21 respectively, which is provided therefor in portion 4 of said stand 1 and in each guide-rod is provided a threaded hole 22 with which cooperates an adjusting screw 23 the head 24 of which bears for instance through a washer 25, on the lower surface of said portion 4 of stand 1.
  • said adjusting devices could be dispensed with.
  • a movable frame 26 formed by two vertical walls 27, 28 respectively, the outer spacing of which is approximately equal to the corresponding inner spacing of stand 1, and by two slanting walls 29, 30 respectively, which join the walls 27 and 28.
  • Each cable 14 passes over the upper portion of the movable frame 26, is introduced in the corresponding hole 31, 32, 33, or 34 and then passes underneath the movable frame towards the corresponding guide-rod 17 to which it is made fast.
  • the playback deck is suspended in four points through zigzag cables, said zigzag arrangement being due to the presence of the movable frame 26.
  • a cap 35 is provided on each foot or adjusting screw 2.
  • the feet 2 are screwed up until the cap 35 bears on the corresponding foot 9 to 12 of the movable framing and clamps said framing against portion 4 of the stand 1.
  • FIG. 12 is shown an embodiment in which both ends of cable 14 are made fast respectively, to the corresponding feet of the movable framing and to the fixed stand 1 while an adjustment in the length of said cable 14 is provided by means of an adjusting device 36.
  • an adjusting device 36 At least in the upper portion 4 of stand 1 is provided a hole 37 which gives access to said adjusting device 36.
  • the suspension device shown in FIG. 13 comprises a movable framing 38 having a flat upper surface 39 and side walls 40 arranged about a fixed stand 41.
  • the movable framing 38 is suspended from the fixed stand 41 through four cables and two movable frames 26 as described above with reference to FIG. 11.
  • the cables are attached by soldering.
  • the movable framing 38 has a lower wall 43 provided with openings 44 through which pass the feet 42.
  • the size of the openings 44 is such that the movable framing 38 can perform sidewise movements with a large enough amplitude Without the feet 42 abutting the wall 43.
  • said device is provided with means for clamping the movable framing 38 against the fixed stand 31 and for clamping the movable frames 26 relative to the movable framing 38.
  • the feet 42 can be adjusted in height relative to the fixed stand and have extensions 42/2 which can bear on the edges of the openings 44.
  • two clamping lugs 45 are provided underneath said frames 26 to bear thereon and through a set screw 46 on wall 43 of movable framing 38.
  • the suspension cables can be made fast to the movable framing or to the fixed stand through a resilient damping element, to let the movable frame perform a vertical movement with the required amplitude.
  • a resilient damping element to let the movable frame perform a vertical movement with the required amplitude.
  • Such resiliency can be due to the material used for making the intermediate movable frames.
