Abstract

A control device (1) for flush tank drain valves has a control member (2); a tie (5); a first lever system (7) connecting the tie (5) to the control member (2); a second lever system (8) connecting the tie (5) to a drain valve; and a connecting bush (17), which has a seat (28) engaged by a threaded portion (20) of the tie (5), and is hinged to the second lever system. The threaded portion (20) has a flat longitudinal portion (21), and the seat (28) has a threaded longitudinal sector (32) inside. The connecting bush (17) and the tie (5) are set in a slide position, when the flat longitudinal portion (21) faces the threaded longitudinal sector (32), and are set in a lock position, when the flat longitudinal portion (21) faces the opposite way to the threaded longitudinal sector (32).

Description

  • The present invention relates to a control device for flush tank drain valves.
  • As is known, devices for draining walled-in flush tanks comprise a rocking control plate inside a frame fixed to the bathroom wall; and a tie connected by levers to both the control plate and a drain valve for draining the flush tank. More specifically, when the user presses the control plate, the tie is moved towards the control plate, and raises the drain valve by means of a square lever. The tie is normally defined by a screw, which engages a nut screw, in turn hinged to the square lever connected to the drain valve.
  • Devices of the above type are fairly versatile structurally, by adapting to different depths of the tank inside the wall. More specifically, this is done by changing the position of the square lever with respect to the wall by rotating the screw defining the tie, and so moving the nut screw along the screw.
  • Though effective in adapting the device, the above method is not altogether straightforward. In fact, rotating the screw may at times prove a long, painstaking job, in the event of the screw and nut screw threads crossing.
  • It is an object of the present invention to provide a drain valve control device designed to provide a straightforward, low-cost solution to the problems of the known art.
  • According to the present invention, there is provided a control device for flush tank drain valves, comprising a control member, a tie, a first lever system connecting said tie to said control member, a second lever system connecting said tie to a drain valve, and a connecting bush engaged in rotary manner by said tie and hinged to said second lever system; said control device being characterized in that said tie comprises a flat longitudinal portion, and a number of fastening members located at and on the opposite side to the flat longitudinal portion; and said connecting bush comprises a lateral wall facing said tie and having a longitudinal fastening sector engageable by said number of fastening members; said tie and said connecting bush being set in a slide position, when said flat longitudinal portion faces said longitudinal fastening sector, and being set in a lock position, when said flat longitudinal portion faces the opposite way to said longitudinal fastening sector.
  • A non-limiting embodiment of the invention will be described by way of example with reference to the accompanying drawings, in which:
    • Figure 1 shows a lateral section of a preferred embodiment of the device according to the present invention;
    • Figure 2 shows a view in perspective of a tie forming part of the Figure 1 device;
    • Figure 3 shows a view in perspective of a connecting ring forming part of the Figure 1 device;
    • Figure 4 shows a view in perspective of a connecting bush forming part of the Figure 1 device;
    • Figure 5 shows a lateral section of connection of the Figure 1 device tie and connecting bush in a slide position;
    • Figure 6 shows a lateral section of connection of the Figure 1 device tie and connecting bush in a lock position.
  • Number 1 in Figure 1 indicates as a whole the flush tank drain valve control device according to the present invention.
  • Device 1 comprises a manual control member 2 defined, in the example shown, by a push plate pivoting inside a frame 3 fixed in known manner to a wall 4; a tie 5 defined by a screw 6; a lever 7 for transmitting motion from push plate 2 to tie 5; and a square lever 8 for transmitting motion from tie 5 to a known flush tank drain valve not described for the sake of simplicity.
  • Lever 7 comprises two centre pins 9 extending on opposite sides and hinging it to two appendixes 10 of frame 3; a first end 7a hinged to a connecting ring 11, which is engaged by screw 6 and rests on a head 6a of screw 6; and a rounded second end 7b resting on an inner appendix 12 of push plate 2.
  • Square lever 8 is hinged by its mid-portion 13 to a fixed pin 14, and comprises a first end 8a hinged to tie 5; and a second end 8b, in which is formed a slot 15 engaged by a rod 16 connected to the drain valve. More specifically, first end 8a of square lever 8 is hinged to a connecting bush 17 engaged by screw 6.
  • As shown in Figure 2, screw 6 defining tie 5 comprises said head 6a, in which is formed a slot 18 for a screwdriver; and a shank 19, in turn comprising a threaded portion 20, and a non-threaded portion 19a located adjacent to head 6a and engaging ring 11. Threaded portion 20 has a flat longitudinal portion 21 extending along the whole of threaded portion 20; and non-threaded portion 19a has a longitudinal fastening rib 22 aligned with flat longitudinal portion 21.
  • As shown in Figure 3, ring 11 comprises two pins 23 extending on opposite sides and engaged by first end 7a of lever 7; and an inner wall 24, in which are formed two diametrically opposite recesses 25 engaged alternatively by fastening rib 22.
  • As shown in Figure 4, connecting bush 17 is defined by a substantially parallelepiped-shaped structure 26, which comprises two lateral pins 27 extending on opposite sides and engaged, in use, by first end 8a of square lever 8. A substantially cylindrical seat 28 is formed in structure 26, is engaged by screw 6, and is defined by two annular end portions 29, and by a lateral, e.g. semicircular, wall 30 extending between the two annular end portions 29. Lateral wall 30 being semicircular, seat 28 has two opposite end openings formed in the two annular end portions 29, and one lateral opening 31. Seat 28 also has a projecting threaded longitudinal sector 32 projecting radially inwards from lateral wall 30, so that connecting bush 17 defines a nut screw engaged by screw 6.
  • Threaded portion 20 defines fastening members which cooperate with threaded longitudinal sector 32, which therefore defines a longitudinal fastening sector.
  • Flat longitudinal portion 21 of screw 6 and threaded longitudinal sector 32 of connecting bush 17 enable troublefree position adjustment and locking of connecting bush 17 along tie 5.
  • More specifically, as shown in Figure 5, when screw 6 is positioned with flat longitudinal portion 21 facing threaded longitudinal sector 32 of connecting bush 17, device 1 is set in a slide position permitting relative slide between screw 6 and connecting bush 17. And conversely, as shown in Figure 6, when screw 6 is positioned with the thread of threaded portion 20 engaging threaded longitudinal sector 32 of connecting bush 17, device 1 is set in a lock position locking screw 6 and connecting bush 17 to each other.
  • In the slide position and lock position, screw 6 is prevented from rotating by fastening rib 22 alternatively engaging one of the two recesses 25 in ring 11.
  • In actual use, in the slide position (Figure 5), connecting bush 17 is slid along screw 6 into the correct position between square lever 8 and push plate 2; at which point, screw 6 is rotated, possibly using a screwdriver, into the lock position (Figure 6) in which the thread of screw 6 engages the thread of threaded longitudinal sector 32 of connecting bush 17. Rotation of screw 6 into the lock position releases fastening rib 22 from the slide-position recess 25, and engages it inside the lock-position recess 25.
  • As will be clear from the above description, in device 1 according to the present invention, the screw-nut screw coupling defined by tie 5 (screw) and connecting bush 17 (nut screw) provides for fast, easy adjustment of the parts (tie 5 and connecting bush 17) to adapt to different requirements.
  • Finally, threaded longitudinal sector 32 and threaded portion 20 may be replaced by other types of fastening members, such as projecting transverse ribs, on tie 5, engaging respective grooves inside seat 28.
