Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a locking system for doors, a system which can be used in particular for an access door of a housing for electrical equipment, and more particularly to a locking system for cabinet doors.

[0002] Electrical equipment, especially equipment for data processing and telecommunications processing, is usually mounted in an electronics housing to protect it. For this purpose, the mounting rack is placed in a housing for mounting electrical equipment, which is usually protected as a conventional 19-inch system. The dimensions of this type of electrical equipment are standardized as are the dimensions of the outside of the housing. However, there is an ongoing shift in this field from conventional 19-inch systems to metric systems, where the dimensions of the equipment protected are slightly larger than those of conventional 19-inch systems. Having this new equipment have metric dimensions in the presence of the housing, fitting the mounting rack in such a housing, exactly fitting the new dimensions of the metric equipment, but the outer dimensions of the housing itself It is also desired that does not change. The access door to the housing is equipped with a locking system, in which a number of parts are located inside the cabinet door and these parts are protruding members such as buttons, switches, cable connectors, etc. of larger equipment with the new metric system Is a problem here. Therefore, it is an important object of the present invention to provide a locking system that is as compact as possible.

There are various types of electronics housings, such as cabinets with right-handed or left-handed doors, and doors with one-point, two-point or three-point locks. In the case of a one-point lock, the door has a locking lip on the side edge and in the case of a two-point locking system,
The door has a locking function on its top and bottom edges, and in the case of a three-point system, the door has a locking lip on its side edges, similar to a one-point locking system, and a top lip, similar to a two-point system. It has a lock function on the bottom edge. It is a further object of the present invention to provide a locking system that can be used in all the situations described above and that has as few parts as possible.

As is well known, one for two-point lock
The handle locking system includes two locking bars oriented upward and downward from the handle, respectively, to achieve locking at the respective top and bottom edges of the door. By turning the handle, the locking bar moves vertically to effect locking and unlocking, respectively. For this purpose, the locking bar is provided with equally spaced holes in which gears connected to the handle engage. In the case of the locking systems used in practice up to now, said gears are rotatably mounted in a block-shaped housing consisting of two substantially identical half-housings which are inseparably connected to one another. It can be installed in two different directions on the door surface, i.e. with the housing rotated 180 degrees with respect to each other, so that it can be used with both left-handed and right-handed doors. This means that the gear housing is symmetrical with respect to a central plane parallel to the door panel, so that the gear housing has a relatively large dimension perpendicular to said plane.

It is an object of the present invention to provide a locking system having these smaller dimensions. In particular, it is an object of the invention to provide a locking system in which the axial distance between the locking lip and the door panel is as short as possible.

In the case of the one-point locking system, there is no vertical bar, but a slidable bar member with equally spaced holes is effectively housed in the gear housing to stop the handle, as described above. Mesh with gears. In contrast, in the case of a two-point and three-point locking system, the locking bar described above is effectively present. As with any locking bar, in the case of a conventional locking system, the gear is surrounded by a gear housing, while the gear housing cannot be opened without breaking it, so the gear housing is It can be made with only one point, two point or three point systems and must be selected beforehand in the manufacture of the gear housing. This is inconvenient in the manufacture of gears, meaning that a relatively large number of different parts must be stored as stock.

[0007] It is therefore a further object of the present invention to provide a locking system that can be used with a reduced number of parts for all types of doors.

According to an important aspect of the invention, the gear is mounted directly on the central shaft of the control handle, and the housing is a bottomless housing which is not fixed over the gear until said gear is mounted on the control handle. It is. Therefore, one point locking system, 2
It is not necessary to decide which type of point or three point to use, and whether to use left-handed or right-handed, until the locking system is secured to the door.

[0009] These and other aspects, features, and advantages of the present invention are illustrated by the following description of a preferred embodiment of a locking system according to the present invention with reference to the drawings, wherein like reference numerals indicate like or equivalent parts. This will be described in more detail.

FIGS. 1A and 1B show the front and back, respectively, of a part of a door plate 1 with a locking system 2 attached at three points in a closed position, while FIGS. 2A and 2B show an open position. Or a similar perspective view of the locking system 2 in the open position. In this example, the door 1 is a right-handed door, which shows a general view from the position of the user, with the hinges arranged along the right-hand edge of the door.

[0011] The locking system 2 includes a central shaft 11 rotatable with respect to the door panel 1 and a rotation axis 11A oriented substantially perpendicular to the door panel 1. For rotation of the central shaft 11, the locking system 2
Includes a control handle 10 oriented substantially perpendicular to the central shaft 11. Although not essential for technical function, in the locking system 2 in the closed state as shown in FIG. 1A, the control handle 10 has a vertical orientation, and as shown in FIG. When the is moved from the closed position to the open position, it is desirable that the central shaft 11 rotates more than 90 °. The rotational movement of the control handle 10 from the closed position to the open position is indicated by the curved arrow P1 in FIG. 2A.

The locking system 2 is mounted near the outer edge 1C, which is the left edge of the door panel 1 in this example. The locking lip 50 is connected to the central shaft 11
Is combined with In the closed position of the locking system 2, the locking lip 50 is oriented from the central shaft 11 to the outer edge 1C of the door panel 1 so that the locking lip 50 can act on the corresponding locking lip or protect it It can be combined with a corresponding locking opening made in the upper corner of the cabinet. The closed position of the locking lip 50 is clearly shown in FIG. 1B. Central shaft 11
Is rotated by the control handle 10 to the unlocked position of the locking system, the locking lip 50 rotates away from the outer edge 1C of the door panel 1, as shown by arrow P2 in FIG. 2B.

The locking system 2 shown in the embodiment also comprises two locking bars extending substantially vertically along the back wall 1B of the door panel 1 in the directions of the bottom edge and the top edge of the door panel 1, respectively. 70 and 8
Contains 0. The locking bars 70 and 80 are vertically movable and are connected to the central shaft by a method described later, and the rotation of the central shaft 11 causes the locking bars 70 and 80 to move in the axial direction. When the locking system 2 is in the closed position, the locking bar 70
And 80 are relatively long in the vertical direction. When in this position, a lock is achieved between the bottom edge and the top edge of the door panel 1 and each of the bottom edge and the top edge of the protective cabinet, and such a lock can also be achieved in a conventional manner. And is not illustrated here for the sake of brevity. Arrow P in FIG. 2B
As shown at 3 and P4, respectively, when the central shaft 11 is rotated by the control handle 10 to bring the locking system 2 to the open position, the bottom locking bar 70 is raised upwards to unlock at the bottom edge of the door panel. The upper locking bar moves downward to move and unlock the upper edge of the door panel 1.

The locking system 2 further includes a lock housing 40 fixed by screws 41 to the rear side 1 B of the door plate 1. The shape of the lock housing 40 is substantially block-shaped, the top wall 42 extends substantially parallel to the door panel 1, two side walls 43 ₁ and 4
3 ₂ substantially vertically and substantially perpendicularly extending with respect to the door panel 1, ₂ two terminal side walls 44 ₁ and 44 substantially horizontally, and extending substantially perpendicular to the door panel 1. The upper end 71 of the bottom locking bar 70 and the lower end 81 of the upper locking bar 80 are guided in the lock housing 40 in a sliding manner.

The locking bars 70 and 80 are, in principle,
Any suitable profile cross section may be provided.
The exemplary locking bars 70 and 80 have the shape of a platelet that is substantially rectangular in profile. On the one hand the relatively simple manufacturing possibilities are thereby associated with a relatively high strength, on the other hand the lock housing 40 for sliding and guiding can be of a simple construction. In this example,
Lock housing in which the lower end portion 81 of the upper locking bar 80 which is supported by the first side wall 43 ₁ of the inner wall of the lock housing 40 which faces the open side edge 1C of the door panel 1, facing away from the open side edge 1C Forty second
Upper end 71 of the bottom locking bar 70 which is supported by the side wall 43 ₂ of the inner wall of the is shown. The passage opening 45 ₁
For this purpose the upper end 7 of the bottom locking bar 70
1 is an opening having a contour corresponding to the cross-sectional contour of _{No. 1} and is arranged on a wall 441 on the bottom end face side of the lock housing 40. The passage opening 45 ₁ in the wall 44 ₁ of the bottom end face side is directly connected to the second side wall 43 ₂ of the lock housing 40.

Since the vertical dimension of the lock housing 40, that is, the length of the side surface thereof, can be made sufficiently large, the ends 71 and 81 of the locking bars 70 and 80 in the open position are completely attached to the housing 40. Combine.
However, in the embodiment shown, the upper end 7 of the bottom vertical locking bar 70 is in the open position.
1 is a wall 44 ₂ of the upper end face side, the lock housing 40
Protruding from. For this purpose, a passage opening 46 _2,
Wall 44 of the upper end side connected to the second side wall 43 _{2 2}
Placed in In a similar manner, the passage openings 46 _1, to pass the bottom end 81 of the upper locking bar 80 in the closed position, the bottom end wall 44 ₁ connected to a first aspect wall 43 ₁
Placed in Therefore, the lock housing 40 is substantially mirror-image-symmetric with respect to the vertical direction of the central plane extending through the rotation axis 11A of the central shaft 11.

In the rear perspective views of FIGS. 1B and 2B, the locking bars 70 and 80 are shown to be bent in a suitable manner. Regarding the top vertical locking bar 80, it can be seen that the bottom end 81 communicates with the central member 83 via the S-bend 82. Bottom vertical locking bar 7
0 also has a central member 73 that can be connected to the upper end 71 via an S-bend, but in the embodiment shown two opposite S-bends 72A and 72A.
2B and a linear member 72C disposed therebetween
To the upper end 71. As shown by the dotted lines in FIG. 1B, substantially U-shaped members 72A, 72B, 72
C allows the bottom locking bar 70 to be sufficiently far away from the space 3 that in the closed position a locking mechanism can be provided on the control handle 10, but for simplicity this locking mechanism is not illustrated in the figure. The S-bends 82, 72A and 72B are provided with vertical locking bars 70 and 8 respectively.
The central members 73 and 83 are formed in an appropriate size so as to be linearly arranged with respect to each other.

The locking bars 70 and 80 can have a length corresponding to the vertical dimension of the door panel 1 calculated from the lock housing 40, so that the respective locking bars 70 and 80
Extending completely from the bottom edge and the top edge of the door panel 1 respectively. However, this requires that the locking bars 70 and 80 have relatively large dimensions,
Also, the locking bars 70 and 80 must be made to size each door panel at the location where the locking system 2 in question is mounted.
Therefore, the locking bars 70 and 80 are, for example, 20 to
At their ends facing away from the lock housing, of the order of 40 cm and having a predetermined length, it is preferred that the locking bars 70 and 80 have connecting means for connecting to the respective extension bars. . If such connecting means are designed to provide connection at various axial positions, the locking bars 70 and 8
If a total length of zero can be set for each of the extension bars, the use application can be made with extension bars having a standard length to make a locking bar of variable length. Such coupling means include orthogonal pins protruding from locking bars 70 and 80 that do not mate with holes located in the extension bar.

An embodiment showing the locking system 2 is:
The so-called three-point type, in which the locking of the door panel 1 to the protective cabinet is at three points, namely at the open side edge 1C by the locking lip 50 and at the bottom edge, the top edge respectively by the bottom locking bar 70 and the top locking bar 80 Can be achieved with However, locking can be achieved only with the locking lip 50, so that the locking bars 70 and 80 can be omitted, in which case the locking system is shown as a one-point type. If locking is achieved only by the locking bars 70 and 80, the locking lip 50 is omitted and the locking system is shown as a two-point type.

FIG. 3A shows a conventional lock housing 140.
It is a schematic perspective view of. FIG. 3B shows an outline of the horizontal vertical section, and FIG. 3C shows an outline of the horizontal section.

The conventional lock housing 140 has the shape of a closed box and is formed of two housing members 140A and 140B which are identical to each other and are fixed so as to be inseparable from each other. The gear 120 is rotatably disposed in the housing 140 and has a generally square through hole 121 disposed centrally. Teeth 122 of the gear 120 is shown in cross-section of the longitudinal section and Figure 3C in Figure 3B, their ends, it is seen clearly that extends to the vicinity of the inner wall of the side walls 43 ₁ and 43 ₂ of the lock housing 140. Side views of the ends 71 and 81 of the locking bars 70 and 80 also show when the ends 71 and 81 of the locking bars 70 and 80 are located inside the lock housing 140 and extend along the interior surface of the side wall. 3B to illustrate the end with a number of holes in which successive teeth 122 of the gear 120 mesh. And it is clear that the rotation of the gear 120 produces an axial movement of the locking bars 70 and 80.

The maximum axial travel of the locking bars 70 and 80 is determined by the number of holes 131 located adjacent to the locking bars. In this example, 5
The holes 131 have a width of about 4 mm, and the distance between the holes is shown as about 2 mm. The final positions of the locking bars 70 and 80 are determined before and after the first hole 131 or after the last hole 131.
Determined by tooth 122 knocking to zero. Therefore, the total axial movement section of the locking bars 70 and 80 is 23
mm.

The axial movement of the locking bars 70 and 80 from the closed position to the open position in this case, as shown by arrows P3 and P4 in FIG. 2B, causes the gear 120 to rotate in one direction, ie, FIG. On the left, and Figure 2
This corresponds to the rotation of the control handle 10 indicated by the arrow P1 of A in a certain direction. As described above, in the case of the conventional lock housing 140, the housing member 140
A and 140B are fixed inseparably from each other and the bar member 132 adjacent to the outermost hole 131 forms a stop for the teeth 122 of the gear 120, thus removing the locking bars 70 and 80 from the conventional lock housing 140. Is impossible. The lock housing 140, in which the gear 120 is mounted and in which the locking bars 70 and 80 are mounted for sliding, thus forms a complete unit. This unit will be available in both left-handed and right-handed doors, so that the movement of the locking bar in the direction of the open position is also possible in a position corresponding to the rotation of the gear 120 to the right. , Lock housing 140 and gear 1 described above
20 and the unit formed by the locking bars 70 and 80 are mirror-image-symmetric with respect to a central vertical plane with respect to the rotation axis 11A. During the mounting of the lock housing on the door panel 1, the mounting direction is adapted to the type of door. Notably, the top housing member 140A is shown in FIG. 3A with the top wall 42, and the corresponding wall 142 of the second housing member 140B is a bottom wall. As described above, the conventional lock housing 140 is mirror-image-symmetric with respect to the contact surface between the two housing members 140A and 140B, so that the lock housing 140 can be fixed upside down. One housing member 140A faces downward.

FIG. 3C shows a cross section of a conventional lock housing 140 attached to the rear wall 1B of the door panel 1. As shown in FIG. The decorative frame 12 of the control handle 10 is fixed to the front wall 1A of the door panel 1, and this frame 1
2 is provided with a protrusion 13 extending from the front wall 1A to the rear wall 1B of the door panel through a hole in the door panel 1.
The hole in the door panel 1 has a square shape, and the projection 1
3 is fixed to the hole in the same shape. The size of the hole is slightly smaller than the size of the lock housing 41, a peripheral edge 143 is disposed on the bottom surface 142, and a peripheral edge thereof is formed by the protrusion 13 of the decorative frame 12 projecting through the hole of the door panel 1. Contact with some outer circumference. When the lock housing 140 is in its normal position, it is locked in place for rotation of the peripheral edge 143 with respect to the decorative frame 12 and with respect to the door panel 1. 3C and 3A, such peripheral edges 14
It can be seen that 3 is also provided on the upper wall 42 of the lock housing 140. The edge of the upper periphery is invalid in the arrangement direction shown,
When 0 is fixed on the other circumference, a rotation lock function is achieved.

As clearly shown in FIGS. 3B and 3C, the conventional gear 120 has a central disk 123 and the gear 1
22 are arranged around the disk 123. Top guide ring 124A is located on the top surface of disk 123, and bottom guide ring 124B is located on the bottom surface of disk 123. A support table 125B extends upward from the bottom wall of the housing 140, and the lock housing 1
A support table 125A extends downward from the upper wall 42 of the forty. The disc 123 can be moved with a little play between the bottom surface of the top support table 125A and the bottom support table 12A.
It is located between the upper surfaces of 5B. This play means that the rotation of the disk 123 is possible, but the lock housing 1
The axial movement of gear 120 relative to 40 is substantially impeded. In the lateral direction, the gear 120 is supported by a circular hole in the top support table 125A, which extends with a slight radial play around the periphery of the top ring 124A of the gear 120 and a corresponding hole in the bottom support table 125B. The hole to be made is also the bottom ring 124
It extends along the circumference of A.

In use, the central shaft 11 of the control handle 10 extends from the front of the door panel 1 to an opening in the decorative frame 12, and thereby to the back surface of the projection 13. To fit this projection on the central shaft 11 of the control handle 10, the bottom support table includes an opening or adjustment area 128B. Due to the symmetry, the upper support table has an equivalent adjustment area 128A. From the free end in front of the central shaft 11, the profiled projections 14 are provided with holes 121 in the gear 120 for the rotational connection between the control handle 10 and the gear 120.
Extend to

Although not shown for simplicity, the lock housing 140 can be fixed to the decorative frame 12 by screws, and the decorative frame 12 is
Including bearings for For fixing of the locking lip 50 not shown in FIGS. 3A to 3C, said locking lip is fixed to the gear 120 by screw means, for which purpose the central shaft 11 is provided with a central screw hole.

As can be clearly seen in FIG. 3C, the axial dimension of the conventional lock housing 140 measured along the direction of the axis of rotation of the control handle 10, in other words, the dimension indicated by the letter H in FIG. Big. The gear 120 is positioned to be completely surrounded by the lock housing 140 for the purpose that the support tables 125A and 125B must be on both sides of the disk member 123. Disk 1 to make it symmetric
23 is indispensable that the guide rings 124A and 124B are arranged on both the upper side and the bottom side thereof, and the bottom support table 125B and the upper support table 12
5A both have adjustment areas 128A and 128 large enough to fit the ends of the central shaft 11.
Having B is essential. In addition, it is essential that the lock housing 140 has a peripheral edge 143 on its top surface and its bottom surface. For these reasons, the dimension H is clearly large. As a result, the distance of the locking lip 50 from the back surface 1A of the door panel 1 is clearly large.

FIG. 4A shows a preferred embodiment of a lock housing 140 according to the invention in a perspective view equivalent to FIG. 3A, and FIG. 4B shows a cross section equivalent to FIG. 3C.

FIGS. 4A-4B show that the locking system according to the present invention is greatly simplified as compared to a conventional locking system. The novel locking system according to the invention makes it possible to use the components 11, 12, 1 of the control handle 10 in order to be able to use it even in the presence of the control handle.
3 are the same as those found in FIG. 3C. The gear 20 and the hole 21, which is preferably in the shape of a rectangle, are fixed directly to the free end 14 of the central shaft 11 of the control handle in the present invention. A bottomless housing 40 is located above the gear 20 and the housing is provided in the top wall 42 with the passage opening 6.
1. It has an edge 62 extending around the periphery of the upper collar member 63 of the gear 20. Although not shown for the sake of simplicity, the housing 40 is attached to the decorative frame 12 by screw means.
Fixed directly to Similarly, although not shown for simplicity, the gear 20 is fixed to the central shaft 11 by screw means. If, for a one-point or three-point system, the locking system includes a locking lip 50, the locking lip 50 is held on the gear 20 and / or the central shaft 11 by the screw means.

In the foregoing, it has been stated that the locking system can include two locking bars 70 and 80 in the case of a two-point or three-point system.
The locking bar is slidably held on the inner wall of the side wall 43 of the lock housing.
As mentioned above, in the case of a conventional lock housing, the bar is always connected to the housing and cannot be removed therefrom. However, in the case of the locking system according to the present invention, the problem of left-handed or right-handed doors, the locking bars 70 and 80 are not
4B (left or right in FIG. 4B), and the bottomless housing 40 allows the gears to slide axially over the bars 70 and 80 on which they are mounted. Whether it is located above the bars 70 and 80 attached to 20, etc., is determined during the installation of the locking system on the door panel 1. As a result, the housing 14 comprising the housing members 140A and 140B forming the unit
There is no need to pre-assemble the 0, gear 120 and the two bars 70 and 80 or keep them as stock, the members can be assembled according to the requirements of the use position. The mounting of the housing 40 by the axial direction of the slide is possible, the passage opening 45 ₁ and 46 ₁ in the wall 44 ₁ of the end face side, the wall 44 ₁ of the end face
Bottom fact that extends to the end, the passage opening 45 ₂ in addition the same is on the wall 44 and _second end portion side of the 46
₂ (not seen in Figure 4A),
It can be clearly seen in FIG. 4A.

As can be seen from the cross-section of FIG. 4B, locking of the left-handed or right-handed door during assembly, and the required one-point, two-point or three-point locks, are performed during the assembly. Due to the arrangement of the gear 20 on the right or left side and the mounting of the housing 40 occurring only then, the conventional gear 120 is applied to the locking system 2 according to the invention.
Unlike, gear 20 need not be mirror symmetric. As a result, the gear 20 can have a more efficient shape, and the axial length between the teeth 22 of the gear 20 and the door panel 1 can be reduced.

Furthermore, the upper wall can be completely flat, the peripheral edge 143 along the upper surface can be omitted, and the opening can be fitted to fit the end of the central shaft 11 in the opposite state. Since the portion (128A) does not need to be disposed on the upper side, the lock housing 40
It can be clearly seen in FIG. 4B that the overall length H of the lock housing 140 is compressed compared to the overall length H of the conventional lock housing 140.

FIG. 5 shows the gear 20 and the two locking bars 70 and 8 when the locking system is in the closed state.
0, two end members 71 and 81 in connection therewith
Of the upper surface of FIG. Housing 40 is not shown in FIG. In order to move the locking system in FIG. 5 from the closed position to the open position, rotation of the gear 20 to the left is necessary, and conversely, by rotation of the gear to the right,
The locking system reaches the closed position shown in FIG. The closed position is recognized as a stop and the gear 20 (and the handle 10) is preferably not rotated further. It can clearly be seen in FIG. 5 that the gear 20 cannot rotate any further because the last opening 131 of the bars 70 and 80 has been reached. Two teeth 22 diametrically opposite each other and meshing with these last openings 131
Is hereafter referred to as the "terminal tooth."

In the closed position, it contacts the locking bars 70 and 80, thus preventing further rotation of the gear 20 and the
Teeth 22 _Y of the gear 20 located directly adjacent to the 2 _Z is represented by the term hereinafter "stop teeth". The symmetry is required, end teeth 22 _Z of the closed position is at a position of substantially perpendicular to the street locking bars 70 and 80 of exemplary. When end teeth 22 _Z is relatively deep connected to the opening 131 of the locking bar 70 and 80, in order to allow the size of the stop tooth 22 _Y is fit, the stop tooth 22 _Y As illustrated, closure It is desirable to be inclined at a location with respect to a plane coinciding with the inner surface of the locking bar.

The tooth 22 _{X of the} gear 20 located on another side adjacent to the terminal tooth 22 _Z is also a stop tooth and is beveled in a similar manner. What is shown in the embodiment does not function as a stop. However, if the positions of the locking bars 70 and 80 change with respect to each other in a left-handed or right-handed door so that the locking system is appropriate, in the closed position these additional stop teeth 22 _X will cause (See FIG. 5 to the left).

If the locking system is used with a one-point lock, the locking bar 7 described above is used.
0 and 80 can be omitted. Instead, one auxiliary locking bar 90 (two may be used,
The book is sufficient) is connected to the gear 20. The auxiliary locking bar 90 includes the locking bars 70 and 80 described above.
It has the same shape and opening as the end of the lock bar, and the interaction with the gear 20 is the same, but the length of the auxiliary locking bar can be shorter than that of the locking bars 70 and 80.

If the locking system is one point,
Alternatively, if it is of three points, the locking lip 50 (see FIG. 1B) is fixed to the gear 20. The locking lip 50 in one embodiment has the shape of a plate with a hole therein, the contour of which matches the contour of the hole of the gear 20. It is advantageously a rectangular profile. In the bore of the gear 20, a connecting sleeve is arranged at the free end 14 of the central shaft 11, which on the one hand achieves a rotational lock of this connecting sleeve on the gear 20 and on the other hand a rotational lock of the connecting sleeve on the locking lip 50. To have an outer contour. The connecting sleeve may have a square outer contour. Advantageously, the length of the connecting sleeve is such that the connecting sleeve located at the free end 14 of the central shaft 11 extends into the hole of the locking lip 50 but does not protrude above the upper surface of the locking lip 50.

As described above, according to the present invention, the central shaft 11 of the handle 10 has the opening 131 and is connected to the bar members 71, 81, and 90 which are disposed inside the lock housing 40 in a slidable manner.
