Description

Box or trough for installation in one or two rectangular openings in a thin wall

Background of the invention

The invention relates to a box or trough for installation in one or two rectangular openings in a thin wall, such as metal door, arranged in the box or in the trough bearing and / or guide means for a closure, such as a pinion gear, with toothed or perforated locking rod (s) meshes, or a drive shaft for a rotary latch or Zug- rotary latch, which drive shaft or pinion gear itself from an operation such as a fold out of a trough and / or pivotable hand lever, or an operating knob or by a key plate in a box insertable socket wrench is rotatable, wherein the trough and / or the box in the at least one rectangular opening of the thin wall by means of substantially unyielding clamping means, such as hooks, can be mounted, which engage the rear side of the breakthrough edge.

The invention further relates to a bar closure in which the box or trough is part of the bar closure.

State of the art

Such a bar closure, which can be fastened with a hook and with screws, is already known from EP 0 261 266 A1. From WO 2005/071191 A1, a bar fastener provided with clip fastening is already known, see for example FIGS. 54A to 56A there.

In the case of EP 0 261 266, it is disadvantageous that the fastening takes place by means of screws, which is cumbersome, especially since four screws are required to achieve the tightness are necessary, see, for example, the embodiment of Fig. 30 of this document. In the embodiment according to FIG. 1 of this document, a hook is provided which replaces two screws. The disadvantage here, however, that the hook attachment causes the closure is no longer tight.

For a pivoting lever with cap attachment could be provided Klipsung, which would be provided on the pushed-through pivot lever part, and also a corresponding surface within the cap. For technical reasons, this is difficult because the durability and the absorption of closing forces or external pivoting lever forces are not sufficient. Further disadvantages for both embodiments are that two different pivot levers must be kept in stock.

Object of the invention

The object of the invention is the development of a bar closure, in which only one basic version is necessary, which simplifies storage. To seal a flap is clipped, the Klipsung must withstand only the contact pressure applied to the edge of the cap seal.

solutions

The object is achieved according to the invention that emanate from the box or the well and / or a cup-shaped, the breakthrough inwardly projecting parts of the box and trough cover further substantially compliant clamping device, the cup-shaped, through the opening Inwardly projecting parts of box or trough enclosing cover releasably hold.

So a sufficient attachment is achieved without the aid of screws, simplifies storage and also realizes a sufficient seal. According to a development (claim 2) of the cup-shaped, through the breakthrough inwardly projecting parts of box or trough enclosing lid is engageable in engagement, that the edge of the cup-shaped lid sealingly lays on the rear surfaces of box, trough or thin wall, whereby particularly easy the desired tightness is achieved.

It is also favorable if (claim 3) at least a part of the essentially unyielding clamping devices is formed by wedge-shaped holding elements which extend from the side wall of the breakthrough penetrating part of the box or the trough and which are resiliently held in the direction of the side wall and their free End form an inclined surface for play-free, unyielding support of the box or the trough on the side facing away from the key plate side of the breakthrough edge.

According to another embodiment (claim 4), the inner wall of the cup-shaped lid at least partially on a groove, which correspond to a grooving in side wall portions of the breakthrough projecting part of the box or the trough. This allows a better adaptation to different wall thicknesses of the thin wall.

According to yet another embodiment (claim 5) forms the inner wall of the cup-shaped lid at least partially an elongated projection / recess, which correspond to an elongated recess / projection in side wall portions of the breakthrough projecting part of the box or the trough.

This groove or recess / projection is preferably arranged on the front side of the breakthrough projecting part of the box or the trough (claim 6).

The disassembly is facilitated if the cup-shaped lid preferably at one, preferably the outer end face (at least) a projection for Pulling the lid by hand forms (claim 7).

It is also beneficial if (claim 8) the lid for the breakthrough penetrating part of the box or the trough surrounds all around tight, including possibly the substantially unyielding hook.

According to yet another embodiment, the cover for the breakthrough penetrating part of the box or trough forms guide slots for locking bars (claim 9).

This is particularly useful when the box or the trough is part of a bar closure having a lock box with two opposing, arranged at the outlet ends of locking rods substantially unyielding retaining elements for fixing the lock case in the opening (claim 10).

In such a bar closure, the lock box instead of one of the substantially unyielding holding elements may have an extension formed into a trough (claim 11).

The trough of the bar closure may carry a lug which extends through another rectangular opening (claim 12).

The approach may have a substantially unyielding holding element at its side facing the trough end and / or at its side facing the trough center (claim 13).

Instead of the substantially unyielding retaining element forms according to another embodiment (claim 14), the trough a substantially unyielding hook.

Again, the approach may be enclosed by a cup-shaped lid (Claim 15).

From the approach or the trough further holding elements can go out, which engage the cup-shaped lid in such a way that its cup edge sealingly on the rear surface of the thin wall sets (claim 16).

The inner cup wall can here also have a groove into which engage the further holding elements (claim 17), wherein in particular the creasing of the cup wall is arranged on the end faces (claim 18).

Finally, according to yet another embodiment, the bar closure may be characterized in that the cap preferably forms on an outer end face at least one projection for pulling off the cap by hand (claim 19).

The cap for the approach can surround it all around tight, including possibly the substantially solid hook (claim 20).

Again, it is advantageous if the cap of the lock case a guide for the rod (s) forms (claim 21).

Best Weαe the execution of the invention

Fig. 1A shows in a plan view and Fig. 1B in a side view of a bar lock 10 with a arranged in a lock case 12 drive pinion 14, see Figs. 4A and 4B, with one, or as here, with two locking rods 16, 18th meshes, which drive pinion 14 is rotatable by a lever 20 which can be folded out of a trough 20, see FIG. 8A, or by a socket wrench which can be inserted in a key plate 24, not shown. The trough 20 or the lock case 24 is at least in a rectangular opening 26 and 28 having a thin wall, such as metal door 30, see Fig. 3B, mounted by means (in disassembly direction) substantially unyielding clamps 32, the rear side of the Breakthrough edge 36 engage. The clamping devices are formed by wedge-shaped retaining elements 32, 34, which emanate from the side wall 38, 40 of the opening 26, 28 in the door leaf 30 or the like. Penetrating part of the lock box 12 or the trough 20 and in the direction of the side wall 38, 40 yielding are held and the free end of an inclined surface for play-free unyielding support of the lock box 12 or the trough 20 on the side facing away from the key plate 24 of the breakthrough edge 36 have. From the lock box 12 or the trough 20 more, substantially yielding holding elements 42, 44 can go out, which engage a cup-shaped cover 46 in such a way that the cup rim 48 sealingly lays on the rear surface 50 of the thin wall 30, or on a Surface 52 of this side wall of the aperture 26 of the wall 30 penetrating part of the lock case 46, 146 or trough 120, see Fig. 11 A and 11 B.

In particular, the lock case 12 has two opposing, arranged at the outlet ends of the rods 16, 18 holding elements 32, 34 for fixing the lock case 12 in the opening 26. Instead of one of the unyielding retaining elements 134, a substantially solid hook 234 can be provided, which engages behind the breakthrough edge 136.

If a pivoting lever is used, it is favorable if the trough 20 carries a lug 54 extending through another rectangular opening 28. Instead of the unyielding retaining element, the trough may have a substantially fixed hook 136 at this point. To achieve tightness, the approach 54 may be enclosed by a cup-shaped lid 146. From the neck or the trough, another less strong retaining element may be such, see the reference numerals 42, 44 and 105, respectively, that its cup rim 48, 148 sealingly rest on the rear surface of the thin wall 130. As can be seen in FIG. 11A, the inner cup wall can have a groove 144 into which the further holding elements 148 engage. In particular, it is favorable if the scoring of the cup wall 140 is arranged on the end faces, as shown clearly in FIG. 11A. Conveniently, the cap on at least one outer end face on a projection 56 for removing the cap 46 by hand. The cap 46 or the cup-shaped lid 146 for the neck 54 close this all around tight, including possibly the substantially solid hook 136th

In the embodiment according to FIG. 7, the cap of the lock case 12 forms a guide for the rod 16, 18th The rods 16, 18 may be guided by rod guides 58 which are fixed in the door leaf and may have at their ends according to the embodiment of Fig. 1B rising catches 60. In the embodiment of FIGS. 2A and 2B, instead, the rod carries trunnions 62 which, for example, engage with locking hooks carried by the door frame and thereby lock the door at several points of its extension. The socket wrench drive or pivot lever drive can also carry a cam follower 64 in addition to the pinion, which additionally enables locking possibility in the middle of the cabinet and which can be seen in FIGS. 1A, 3B.

Fig. 1A is an example of a square socket wrench, Fig. 2A is an example of a triangular socket wrench, Fig. 3A is an example of yet another wrench, such as double bit wrench. Referring to Figs. 4A and 4B, the limited perforation of the locking bar in conjunction with bevel gear toothing effects a push-out travel limit for the locking bar. After the locking bar has been combined with the pinion in the illustrated form, it is clipped into the opening 26 in the wall 30 as a pre-assembled assembly, see the arrow 66. Now, the rods according to FIGS. 4D and 4F, depending on whether it is a right door 8 (Fig. 4D) or a left door (Fig. 4F) are mounted, in which they are fitted in the correct position on the pinion, to which Fig. 4E gives an indication. Finally, the sealing and leading lid or cap 46 is then attached to the rods and the clip-like lid receiving side walls of the lock case, as shown in FIG. 5. Accordingly, the pivot lever lock is mounted as shown in FIGS. 9A to 10A: First, the lower end of the trough of FIG. 10A hooked with the hook 234 through the opening 28 in the thin wall 30, see Fig. 10A. Then, the upper end of the trough is clipped with the local lock box in a corresponding opening of the thin wall 30, Fig. 10B. 10E and 10G, the rods are suitably loaded such that, for example, as shown in FIG. 10E, a left door (in which the handle lever is to be turned clockwise to open) results in a right-hinged door in FIG. 10G is provided, it is more convenient if the lever can be rotated counterclockwise to the door to open. Then, the cap is pushed onto the lock case in the manner already described, resulting in the rod guide, as well as a dust-tight enclosure for the pinion, without the need for screws would be required.

As shown in FIG. 8A, the swing lever 22 may include a cylinder lock 68 to lock the swing lever 22 in the tray 20.

The e.g. hook attachment 234 of the trough 20, 120 shown in FIGS. 9A, 9B as well as in FIGS. 10A to 10H and 11A to 11B makes it possible to subsequently slip over (arrow 66 in FIG. 10H) a cap 46, 146 by clip fastening, the cap only having to support the sealing forces for the cap. So far, either a hook or a cap design provided, see the above-mentioned prior art. This requires a double storage, which is no longer necessary with the construction according to the invention. It is even possible, e.g. a hooked trough, see the example of Figures 11A and 11B; for a pivot lever to seal the trough 120 in the area of the cylinder lock 68 later, see in Fig. 9B the dashed line at the bottom of the trough indicated cap or in Fig. 11 A, the cap 146th
