Definitions

  • the invention relates to a locking system for drawer cabinets with several drawers according to the preamble of claim 1.
  • the center of gravity of the cabinet can be shifted to the outside of the standing surface with several drawers open at the same time, resulting in the cabinet falling over Consequence. It should therefore not be possible to open two drawers one after the other or at the same time.
  • a safety lock In another known locking device, the simultaneous opening of two drawers is already prevented by a safety lock.
  • This includes two locking bars that can be moved vertically in opposite directions. As soon as a locking bar is moved in one direction, all other drawers are locked and can no longer be opened.
  • the curve pieces used in this device have such inclined surfaces that the locking rod is moved either up or down. Each drawer is given a different arrangement of the curve pieces to prevent two drawers from opening at the same time.
  • the known locking has the disadvantage that on the one hand different curve pieces are used, so that this results in both additional costs and a larger position bracket is required.
  • a maximum of four different arrangements can be achieved with only two different curve pieces, so that this safety lock is only suitable for drawer cabinets with a maximum of four drawers.
  • the present invention has for its object to provide a locking system for drawer cabinets, which a simultaneous opening of any number of drawers prevented and with as little effort as possible on identical parts.
  • the curve pieces are now at different distances from the locking rod, the curve pieces being arranged differently on each drawer.
  • At least one curve piece is attached to each drawer.
  • the curve pieces can either be attached directly next to the locking bar or at a certain distance from the locking bar.
  • the locking bars are deflected vertically upwards by the curved pieces and held in this position by holding devices. In this position, the locking bars lock all other drawers, so that opening other drawers is not possible.
  • By arranging the curve pieces differently on the drawers it is possible to obtain different drawer configurations. This has the advantage that after opening one drawer all other drawers are locked and that it is not possible to open two drawers at the same time.
  • Another advantage of this locking system is that its application is not limited to drawer cabinets with only four drawers.
  • the number of different drawer configurations can be increased as desired by arranging the curve pieces at several different distances. This results in an unlimited number of different drawer configurations, so that a locking system designed in this way for drawer cabinets with any number of drawers.
  • a locking system designed according to this technical teaching has the further advantage that the curved pieces attached to the drawers are of a uniform design, and thus the production costs can be reduced.
  • Preferred embodiments of the invention are specified in dependent claims 2 to 9.
  • FIG. 1 A locking system for drawer cabinets with four drawers designed according to the technical teaching of this invention is shown in FIG. 1.
  • the locking bars 1, 2 arranged vertically to the right and left of the drawers are provided on their side facing the drawers 3 with cylindrical pins 4 arranged perpendicular to the locking bar.
  • Each locking rod 1, 2 has a pin 4 for each drawer 3.
  • a curve piece 7 is attached to the right and left side walls 5, 6 of the drawers 3. Either a short angle 8 or a long angle 9 is arranged between the curve piece 7 and a side wall 5, 6.
  • FIG. 2 shows the curve section 7 with the short angle 8 and in FIG. 3 the curve section 7 with the long angle 9 is shown enlarged.
  • a stop surface 10 of the short angle 8 is arranged directly in front of the curve piece 7.
  • the stop surface 11 of the long angle 9 is arranged at a certain distance in front of the curve piece 7.
  • the stop surface 10 is a square section of the short angle 8 or the long angle 9, which is arranged at right angles at its front end.
  • the curve piece 7 contains a restoring surface 13 and a guide surface 14 for guiding the pin 4 and thus for deflecting the locking rod 1, 2 when the drawer 3 is pulled out.
  • the restoring surface 13 and the guide surface 14 are connected to one another by a rear wall 15 of the curve piece 7.
  • the guide surface 14 initially extends obliquely in the longitudinal direction and then drops again to the initial level.
  • the restoring surface 13 initially runs parallel to the guide surface 14, but continues horizontally after reaching the highest point to the end of the curve piece 7.
  • the curve piece 7 integrates a stopper 16 on its front side.
  • the stopper 16 is arranged at the same height as the stop surface 10 or 11.
  • the curve pieces 7 are arranged either close to the locking bar 1, 2 or at a certain distance 17 from the locking bar 1, 2.
  • the curve pieces 7 of a single drawer 3 can be arranged at different distances from the locking bar 1, 2.
  • An essential part of the invention is that each drawer 3 of a drawer cabinet has a different arrangement of the curved pieces 7.
  • there are two ways of arranging the curve pieces 7 on the drawer which means that there are four different possible combinations of the curve pieces 7 on a drawer 3.
  • the locking rods 1, 2 and their pins 4 are aligned such that the pins 4 are at the level between the beginning of the guide surface 14 and the restoring surface 13. If a drawer 3 is now pulled out, the stop surface 10 of the short angle 8 or the long angle 9 is guided over the pin 4 and the pin 4 enters the curve piece 7. The obliquely rising guide surface 14 now moves the locking rod 1, 2 vertically upwards until it engages in a holding device, not shown. In this position, the pins 4 of the locking bars 1, 2 are at the same height with the stop surface 10 or the stopper 16 and thus lock the other drawers. When the opened drawer 3 is pushed in, the pin 4 of the locking rod 1, 2 reaches the cam piece 7 in the opposite direction out and moves the locking bar 1, 2 back to the starting position. All drawers 3 are thus unlocked again and any drawer 3 can be pulled out.
