Definitions

  • the present invention relates to a door-locking system, more particularly a locking system for a cabinet door, which system can be used in particular for an access door of a housing for electronic equipment.
  • a door has a locking lip at a side edge; in the case of a two-point locking system, a door has a locking facility at its top edge and its bottom edge; in the case of a three-point system, a door has both a locking lip at its side edge, according to the one-point locking system, and the locking facilities according to the two point system at its top and bottom edges. It is a further object of the present invention to provide a locking system that can be used in all the abovementioned situations with as few parts as possible.
  • a one-handle locking system for a two-point lock comprises two locking bars, directed upwards and downwards respectively from a handle, for operating the lock at the top edge and the bottom edge respectively of a door.
  • said locking bars are shifted in the vertical direction, in order to bring about the locking and unlocking respectively.
  • the locking bars are provided with a pattern of holes in which a toothed wheel connected to the handle engages.
  • said toothed wheel has been rotatably mounted in a block-shaped housing, consisting of two substantially identical housing halves undetachably connected to each other.
  • the housing can be mounted in two different orientations on a door surface, which orientations are rotated through 180° relative to each other.
  • the present invention aims to provide a locking system wherein the axial distance between a locking lip and a door panel can be as small as possible.
  • the toothed wheel housing can be only designed either for a one-point system or for a two-point or three-point system, and the choice must be known in advance when the toothed wheel housing is being manufactured. This is an inconvenience when the toothed wheel housings are being manufactured, and also means that a relatively large number of different parts must be held in stock.
  • the toothed wheel is mounted directly on a central shaft of the control handle, and the housing is a bottomless housing which is not fitted over the toothed wheel until after said toothed wheel has been mounted on the control handle.
  • Figures 1A and 1B show a front view and a rear view respectively of a part of a door plate 1, with a three-point locking system 2 fitted thereon, in the closed position, while figures 2A and 2B show comparable perspective views with the locking system 2 in the opened position or release position.
  • the door 1 is a right-hand door, by which it is meant that, viewed from the user's position, the hinges are situated along the right-hand side edge of the door.
  • the locking system 2 comprises a central shaft 11, which is rotatable relative to the door panel 1, and the axis of rotation 11A of which is directed substantially perpendicular relative to the door panel 1.
  • the locking system 2 comprises a control handle 10, which is directed substantially perpendicular to said central shaft 11.
  • the control handle 10 in the closed position of the locking system 2 it is desirable for the control handle 10 in the closed position of the locking system 2 to have a vertical orientation, as shown in figure 1A, and for the central shaft 11 to rotate through an angle of more than 90° when the locking system 2 is taken from the closed position to the release position, as illustrated in figure 2A.
  • the rotational movement of the control handle 10 from the closed position to the release position is indicated in figure 2A by the curved arrow P1.
  • the locking system 2 is fitted in the vicinity of the free side edge 1C, in this example the left side edge, of the door panel 1.
  • a locking lip 50 is coupled to the central shaft 11.
  • the locking lip 50 In the closed position of the locking system 2, the locking lip 50 is directed from the central shaft 11 towards the free side edge 1C of the door panel 1, so that the locking lip 50 can act upon a corresponding locking lip or engage in a corresponding locking opening made in a corner upright of a protective cabinet.
  • Said closed position of the locking lip 50 is shown clearly in figure 1B.
  • the central shaft 11 is rotated by means of the control handle 10 to the release position of the locking system, the locking lip 50 rotates away from the free side edge 1C of the door panel 1, as indicated by arrow P2 in figure 2B.
  • the locking system 2 in the embodiment shown also comprises two locking bars 70 and 80, which extend along the rear wall 1B of the door panel 1 substantially in the vertical direction, in the direction of the bottom edge and the top edge of the door panel 1 respectively.
  • These locking bars 70 and 80 are axially displaceable in the vertical direction and are connected to said central shaft in a manner that will be described later, in such a way that a rotation of said central shaft 11 results in an axial displacement of the locking bars 70 and 80.
  • the vertical extension of the locking bars 70 and 80 is relatively great.
  • the locking system 2 further comprises a lock housing 40, which is fixed by means of screws 41 to the rear side 1B of the door plate 1.
  • the lock housing 40 is in a substantially block-shaped form, with a top wall 42 extending substantially parallel to the door panel 1, two lateral side walls 43 1 and 43 2 extending substantially vertically and substantially perpendicular to the door panel 1, and two end-face side walls 44 1 and 44 2 extending substantially horizontally and substantially perpendicular to the door panel 1.
  • a top end 71 of the bottom locking bar 70 and a bottom end 81 of the top locking bar 80 are guided in a sliding manner in the lock housing 40.
  • the locking bars 70 and 80 can have any suitable cross sectional contour.
  • the locking bars 70 and 80 are in the form of a strip with a substantially rectangular cross sectional contour.
  • the lock housing 40 for the slide-guiding function thereof can be of a simple construction.
  • the bottom end 81 of the top locking bar 80 rests against the internal surface of the first lateral side wall 43 1 of the lock housing 40 facing the free side edge 1C of the door panel 1, and that the top end 71 of the bottom locking bar 70 rests against the internal surface of the second lateral side wall 43 2 of the lock housing 40 facing away from said free side edge 1C.
  • a passage opening 45 1 is provided for this purpose in the bottom end-face side wall 44 1 of the lock housing 40, the contour of which opening corresponds to the cross sectional contour of the top end 71 of the bottom locking bar 70. Said passage opening 45 1 in the bottom end-face side wall 44 1 connects directly to the second lateral side wall 43 2 of the lock housing 40.
  • the vertical dimension of the lock housing 40 in other words the length of the lateral sides thereof, can be so great that the ends 71 and 81 of the locking bars 70 and 80 in the release position also are fully accommodated in the housing 40.
  • the top end 71 of the bottom vertical locking bar 70 is projecting from the lock housing 40 at the top end-face side wall 44 2 .
  • a passage opening 46 2 connecting to the second lateral side wall 43 2 , is provided in the top end-face side wall 44 2 .
  • a passage opening 46 1 connecting to the first lateral side wall 43 1 , is provided in the bottom end face wall 44 1 , for the purpose of allowing through the bottom end 81 of the top locking bar 80 in the closed position thereof.
  • the lock housing 40 is thus substantially mirror-symmetrical relative to a vertically directed central plane running through the axis of rotation 11A of the central shaft 11.
  • the locking bars 70 and 80 can be bent in a suitable manner.
  • the top vertical locking bar 80 it can be seen that the bottom end 81 passes by way of an S-bend 82 into a central part 83.
  • the bottom vertical locking bar 70 likewise has a central part 73 which by way of an S-bend can connect to the top end 71, but which in the embodiment shown connects to the top end 71 by way of two opposite S-bends 72A and 72B and a straight part 72C situated therebetween.
  • the bottom locking bar 70 leaves clear a space 3, shown by dotted lines in figure 1B, where a lock mechanism can be provided for the control handle 10 in its closed position, but this lock mechanism, for the sake of simplicity, is not shown in the figures.
  • the said S-bends 82, 72A and 72B are dimensioned in such a way that the said central parts 73 and 83 of the vertical locking bars 70 and 80 are situated substantially in line with each other.
  • the locking bars 70 and 80 can have a length that corresponds to the vertical dimension of the door panel 1, calculated from the lock housing 40, so that each locking bar 70, 80 extends from the lock housing 40 as an integral whole to the bottom edge and the top edge respectively of the door panel
  • the embodiment shown of the locking system 2 is a so-called three-point type, which means that locking of the door panel 1 relative to a protective cabinet can be achieved at three points, namely at the free side edge 1C by means of the locking lip 50, and at the bottom edge and the top edge by the bottom locking bar 70 and the top locking bar 80 respectively. It is, however, also possible that a locking is achieved with the locking lip 50 alone, so that the locking bars 70 and 80 can be omitted, in which case the locking system is indicated as a one-point type. If the locking is achieved by means of the locking bars 70 and 80 alone, thus omitting the locking lip 50, the locking system is indicated as a two-point type.
  • Figure 3A shows diagrammatically a perspective view of a known lock housing 140.
  • Figure 3B shows a diagrammatic horizontal longitudinal section thereof, and figure 3C shows a diagrammatic cross section thereof.
  • the known lock housing 140 is in the form of a closed box, constructed of two housing parts 140A and 140B, which are identical to each other and are undetachably fixed to each other.
  • a toothed wheel 120 is rotatably disposed in the housing 140, which toothed wheel 120 has a centrally profiled through hole 121, generally a square hole.
  • the teeth 122 of the toothed wheel 120 are shown in the longitudinal section of figure 3B and in the cross section of figure 3C, and it can be seen clearly that their ends extend until in the vicinity of the internal surface of the lateral side walls 43 1 and 43 2 of the lock housing 140.
  • a side view of an end 71, 81 of a locking bar 70, 80 is also schetched in figure 3B, in order to illustrate that said end is provided with a number of holes 131 in which the successive teeth 122 of the toothed wheel 120 engage when said end 71, 81 of said locking bar 70, 80 is situated inside the lock housing 140 and extends along the internal surface of a lateral side wall. It will then be clear that a rotation of said toothed wheel 120 produces an axial displacement of said locking bar 70, 80.
  • the maximum axial freedom of movement of the locking bar 70, 80 is determined by the number of holes 131 that are provided next to each other in said'locking bar. In the example shown, five of such holes 131, with a hole width of approximately 4 mm and a distance between holes of approximately 2 mm, are present.
  • the extreme positions of the locking bar 70, 80 are then determined by a tooth 122 knocking against the locking bar 70, 80 at a position before the first or after the last hole 131.
  • the total axial freedom of movement of a locking bar 70, 80 is then 23 mm.
  • the known lock housing 140 together with the toothed wheel 120 rotatably mounted therein and the locking bars 70 and 80 slidably fitted therein, thus forms a complete unit.
  • this unit In order to make it possible for this unit to be usable for both left-hand doors and right-hand doors, so that situations in which a displacement of a locking bar in the direction of the release position corresponds to a rotation of the toothed wheel 120 to the right are also possible, the unit formed by the abovementioned lock housing 140, the toothed wheel 120 and the locking bars 70 and 80 is mirror-symmetrical relative to a central plane perpendicular to the axis of rotation 11A. During fitting of the lock housing on a door panel 1, the direction of fitting is then adapted to the type of door.
  • top housing part 140A is shown with a top wall 42 in figure 3A, and the corresponding wall 142 of the second housing part 140B is a bottom wall.
  • the known lock housing 140 is mirror-symmetrical relative to the contact face between the two housing parts 140A and 140B, so that the lock housing 140 can also be fitted upside down, in which case the face 42 of the first housing part 140A then faces downwards.
  • FIG 3C a cross section is shown of the known lock housing 140, fitted on the rear wall 1B of a door panel 1.
  • An ornamental frame 12 of the control handle 10 is fitted on the front wall 1A of the door panel 1, which ornamental frame 12 is provided with a projection 13, extending from the front wall 1A through a hole in the door panel 1 to beyond the rear wall 1B of the door panel.
  • the said hole in the door panel 1 is of a rectangular shape, and the projection 13 is of a corresponding shape, fitting into said hole.
  • the dimensions of said hole are slightly smaller than the dimensions of the lock housing 41, and a peripheral edge 143 is provided on the bottom face 142, which peripheral edge fits round the part of said projection 13 of the ornamental frame 12 projecting through said hole of the door panel 1.
  • peripheral edge 143 When the lock housing 140 is in position, it is secured by said peripheral edge 143 for rotating relative to the ornamental frame 12 and relative to the door panel 1. It can be seen in figure 3C and in figure 3A that such a peripheral edge 143 is also provided on the top wall 42 of the lock housing 140. This top peripheral edge is ineffective in the orientation shown, but fulfils the rotation-locking function when the lock housing 140 is fitted the other way round.
  • the known toothed wheel 120 has a central disc 123, the said teeth 122 being formed on the circumference of said disc 123.
  • a top guide ring 124A is provided on the top surface of the disc 123
  • a bottom guide ring 124B is formed on the bottom surface of the disc 123.
  • a supporting table 125B extends upwards, and from the top wall 42 of the lock housing 140, a supporting table 125A extends downwards.
  • the disc 123 is disposed with slight play between a bottom surface of the top supporting table 125A and a top surface of the bottom supporting table 125B.
  • the central shaft 11 of the control handle 10 runs from the front side of the door panel 1 through an opening in the ornamental frame 12, and in doing so extends beyond the rear surface of the said projection 13.
  • the bottom supporting table comprises an opening or accommodation area 128B.
  • the top supporting table comprises a comparable accommodation area 128A. From the free end of the central shaft 11 onwards, a profiled projection 14 extends into the hole 121 of the toothed wheel 120, for the rotational coupling between control handle 10 and toothed wheel 120.
  • the lock housing 140 can be fixed to the ornamental frame 12 by means of screws, not shown for the sake of simplicity, and the ornamental frame 12 also comprises bearings for the control handle 10.
  • a locking lip 50 which is not shown in figures 3A to 3C, said locking lip is fixed by means of a screw to the toothed wheel 120, for which purpose the central shaft 11 is provided with a central screw hole.
  • the axial dimension of the known lock housing 140 in other words the dimension indicated by the letter H in figure 3C, measured along the direction of the axis of rotation 11A of the control handle 10, is relatively great.
  • the toothed wheel 120 lies fully enclosed in the lock housing 140, for which purpose a supporting table 125A, 125B must be present on either side of the disc part 123.
  • the disc 123 must be provided both at its top side and at its bottom side with a guide ring 124A, 124B, and both the bottom supporting table 125B and the top supporting table 125A must be provided with an accommodation area 128B, 128A which is large enough to accommodate the end of the central shaft 11.
  • lock housing 140 must be provided with a peripheral edge 143 on both its top surface and its bottom surface. Because of this all, the said dimension H is fairly great. Consequently, the distance of the locking lip 50 from the rear surface 1A of the door panel 1 is fairly great.
  • Figure 4A shows a perspective view, comparable to figure 3A, of a preferred embodiment of a lock housing 40 according to the present invention, and figure 4B shows a cross section comparable to figure 3C.
  • FIGs 4A-B illustrate that a locking system according to the present invention has been greatly simplified compared with the known locking system.
  • the parts 11, 12 and 13 of the control handle 10 are identical to those shown in figure 3C, because the new locking system according to the present invention is intended to be suitable for use also in the case of existing control handles.
  • the toothed wheel 20 with its profiled hole 21, preferably a square hole, is now fixed directly on the end 14 of the central shaft 11 of the control handle 10.
  • a bottomless housing 40 is positioned over the toothed wheel 20, which housing has in its top surface 42 a passage opening 61, the edge 62 of which extends around a top collar part 63 of the toothed wheel 20.
  • the housing 40 is fixed directly on the ornamental frame 12 by means of screws not shown for the sake of simplicity.
  • the toothed wheel 20 is fixed on the central shaft 11 by means of a screw, likewise for the sake of simplicity not shown. If the locking system comprises a locking lip 50 for a one-point or a three-point system, said locking lip 50 is clamped by said screw on the toothed wheel 20 and/or on the central shaft 11.
  • the locking system can comprise two locking bars 70 and 80 in the case of a two-point or a three-point system. Said locking bars rest slidably against the internal surface of the lateral side walls 43 of the lock housing. As discussed above, in the case of the known lock housing the bars are constantly associated with the housing, and cannot be removed from it.
  • the locking bars 70 and 80 are coupled in a suitable manner to the one side or the other side of the toothed wheel 20 (left or right in figure 4B), and the bottomless housing 40 is then positioned over the toothed wheel 20 and the fitted bars 70 and 80, by sliding the bottomless housing 40 in the axial direction over the toothed wheel 20 and the fitted bars 70 and 80.
  • the toothed wheel 20 needs not be symmetrical, as is the case with the known toothed wheel 120, because during the assembly the locking system 2 according to the present invention is adapted to a left-hand or right-hand door, and to a desired one-point, two-point or three-point lock by positioning the bars 70, 80 to the left or right of the toothed wheel 20 and only then fitting the housing 40.
  • the toothed wheel 20 can have a more efficient shape, and more particularly the axial distance between the teeth 22 of the toothed wheel 20 and the door panel 1 can be reduced.
  • Figure 5 shows diagrammatically a top view of the toothed wheel 20 and two end parts 71 and 81 of two locking bars 70 and 80 in engagement therewith, the locking system being in the closed position.
  • the housing 40 is not shown in figure 5.
  • rotation of the toothed wheel 20 to the left is necessary in figure 5; conversely, the locking system has reached the closed position shown in figure 5 by rotation of the toothed wheel to the right.
  • the closed position can be felt as a stop, and that the toothed wheel 20 (and thus the handle 10) can not be rotated further.
  • the toothed wheel 20 cannot rotate further to the left because the last openings 131 of the bars 70 and 80 have been reached.
  • the two teeth 22, situated diametrically opposite each other that are in engagement with these last openings 131 will be indicated by the term "end tooth".
  • the teeth 22 Y of the toothed wheel 20 situated directly next to the end teeth 22 Z , which teeth 22 Y in the closed position come into contact with the locking bars 70 and 80 and thus prevent a further rotation of the toothed wheel 20, will be indicated by the term "stop tooth”.
  • the end teeth 22 Z are in an orientation substantially perpendicular to the locking bars 70, 80 in the closed position, as shown.
  • the dimensions of the stop teeth 22 Y are adapted; preferably, and as illustrated, the stop teeth 22 Y are bevelled according to a plane that in this closed position coincides with the internal surface of the locking bars.
  • the teeth 22 X of the toothed wheel 20, situated at the other side next to the end teeth 22 Z are also stop teeth and are bevelled in a similar way. In the embodiment shown they are not effective as a stop. However, if the locking bars 70 and 80 change position with each other, which corresponds to making a locking system suitable for a left-hand or a right-hand door, it is those other stop teeth 22 X that in the closed position prevent further rotation of the toothed wheel 20 (then to the left in figure 5).
  • auxiliary locking bar 90 (two may also be used, but one is sufficient) is then coupled to the toothed wheel 20.
  • This auxiliary locking bar 90 is of a shape and has openings that are comparable to the ends of the locking bars 70 and 80 described above, and the interaction with the toothed wheel 20 is accordingly the same, but the length of the auxiliary locking bar 90 can then be much shorter than that of the said locking bars 70 and 80.
  • a locking lip 50 (see figure 1B) is fixed on the toothed wheel 20.
  • a locking lip 50 is in the form of a plate with a hole provided therein, the contour of which hole corresponds to the contour of the hole in the toothed wheel 20. That is advantageously a square contour.
  • a coupling sleeve is placed on the end 14 of the central shaft 11, which coupling sleeve has an external contour that provides rotation locking of, on the one hand, this coupling sleeve relative to the toothed wheel 20 and, on the other hand, this coupling sleeve relative to the locking lip 50.
  • the coupling sleeve advantageously has a square external contour. It is advantageous if the length of the coupling sleeve is such that the coupling sleeve placed on the end 14 of the central shaft 11 extends into the hole of the locking lip 50, but does not project above the top surface of the locking lip 50.
  • the present invention thus provides a locking system 2 with a lock housing 40 inside which a toothed wheel 20 is disposed in a rotatable manner, which toothed wheel can be rotated by a central shaft 11 of a handle 10, and is in engagement with a bar part 71; 81; 90 which is provided with openings 131 and is disposed in a slidable manner inside the lock housing 40.
  • Assembly of the locking system is carried out at the application location.
  • the central shaft 11 is inserted through a door panel 1, and the toothed wheel 20 is fitted directly on the free end of this central shaft.
  • one or more bar parts 71; 81; 90 is/are connected to the toothed wheel 20.
  • the lock housing 40 is in the form of a bottomless cap which is shifted over the toothed wheel 20 and the bar parts 71; 81; 90 and is then fixed relative to the door panel 1.
