Definitions

  • the invention relates to a device for turning sheets of documents standing on a stand, in particular sheet music, with a turning member encompassing the sheet to be turned on its upper edge, which projects downward from a horizontal arm, which is held by a rod rotatable about a vertical axis is connected to a foot actuator via a transmission.
  • a sheet turner is known from US-A 1 716 693, which is only intended for attachment to a piano, with considerable structural changes also having to be made here in order to guide the cable from the music stand to the pedal.
  • the sheet to be turned is not gripped at its upper edge, but is grasped by an organ standing on its side with two clamps.
  • this known turning device can be fastened to a commercially available music stand by means of clips, this considerably reduces the stability of the entire device, in particular when one of the two pedals is actuated.
  • the invention has for its object to design a device of the type mentioned in such a way that it can be used in existing music stands or the like. Without having to make any structural changes to them.
  • the gear has a horizontal shaft, on the end of which protrudes from the housing, the foot actuating member, which is designed as a two-armed lever, is removably attached.
  • the transmission can have a vertical shaft, on the end of which protrudes from the housing, the rod is releasably attached.
  • the horizontal arm is detachably and adjustably fastened to the upper end of the rod by means of a sliding bearing and carries a turning member at both ends.
  • the turning organ to the side to be turned or the following side, in order to swivel the arm about 180 ° if necessary via the foot actuation organ; if the turning element has been plugged onto the next but one page, the arm can be quickly turned back after the first turning, the overturned side being turned back so that it can also be turned mechanically the next time the page is turned.
  • a box-shaped housing 10 with three feet 12 can be seen.
  • the vertical foot 16 of a music stand 18 is inserted, on which the document 20 is arranged essentially standing.
  • the foot 16 of the Music stand 18 is clamped in the housing 10 via a locking screw 22.
  • a U-shaped, downwardly open bracket 26 is used to turn the sheets 24 of the writing material 20, the vertical clamping plates 28 of which grip around the sheet 24 on its upper edge.
  • the bracket 26 is fastened via a nut 30 to a bolt 32 which is inserted into a bore 34 in a horizontal arm 36 in a freely rotatable manner.
  • the arm 36 has several such bores 34, so that the position of the bracket 26 on the arm 36 can be adapted to the size of the writing material 20.
  • the arm 36 is connected to a rod 38 which is arranged in the vertical position behind the foot 16 of the music stand 18.
  • the lower end of the rod 38 is connected via a clamping screw 40 to a vertical shaft 42 which protrudes above the top 14 of the housing 10.
  • the shaft 42 carries in the housing 10 an output gear 44 of a bevel gear 46, the drive gear 48 has a horizontal shaft 50.
  • the horizontal shaft 50 protrudes over the front end face 52 of the housing 10 and carries a foot actuating member 54. This is designed as a plate which is fastened to the shaft 50 and can be pivoted with the latter about its horizontal axis.
  • the plate of the foot actuating member 54 is pressed down on one side with the foot, approximately in the direction of the arrow P in FIG is rotated by approximately 150 ° in the direction of arrow S. This also rotates the arm 36 and takes the sheet 24 with it via the bracket 26 until it comes to rest on the opposite side. In the opposite direction, the sheet 24 can be pivoted back again.
  • the vertical rod 38 is designed to be telescopically adjustable and, for this purpose, has a rod part 38 ′ which is thinner in diameter and which is seated in the lower part of the rod 38 by means of a clamping screw 56.
  • the arm 36 is also telescopically adjustable horizontally and can be locked by means of a clamping screw 58 on a thinner arm section 36 'which is formed in one piece with the rod part 38'.
  • the clamping plates 28 of the strap 26 are arranged very close to each other and grip the sheet not shown, to be turned very tightly, preferably with little spring pressure, so that it does not get stuck on a projection 60 of the music stand 18 and slip out of the strap 26 when turned.
  • FIG. 4 shows how the hollow foot 16 of the commercially available music stand 18, the raised tripod 62 of which is indicated, is placed on a pin 64 fastened in the housing 10 by means of the locking screw 22 and fixed thereon by means of a clamping screw 66.
  • FIGS. 5 to 7 show a particularly advantageous embodiment in which the two front feet 12 'of the housing 10 are fastened to the housing 10 such that they can pivot about vertical axes 68.
  • the foot actuator 54 consists of a two-armed lever 70, which is releasably attached to the shaft 50 via a locking screw 72. With these measures, the device can be quickly disassembled to be packed in a suitcase or the like.
  • the uppermost rod part 38 ′′ carries a clamping member 74 with a clamping screw 76, via which a sliding bearing 78 is fastened to the clamping member 74.
  • the sliding bearing 78 can be pivoted downward about the axis of the clamping screw 76 in the direction of the arrow.
  • the arm 36 ′′ designed as a rod, which can be fixed in the central region by a locking screw 80 in the sliding bearing 78.
  • the arm 36 ′′ carries at both ends a turning member, which consists of two clamping plates 28, which are fixed by means of a clamping screw 82 in a bracket 84, which projects downward at the associated end of the arm 36 ′′.
