Description

Bar lock for hole mounting of a thin wall (indirect fixation by clip).

The invention relates to a lock of bars for mounting in a hole in a thin wall, comprising a head part such as the flange, the plate of the key, the grip rosette or a lever cavity of performance, with an edge area that covers the outer edge of the hole, a body part that comes out of the head part and that after assembly it crosses the hole, from which they are formed or supported clamping surfaces, which after the mounting are attached to the inner edge of the wall hole thin.

From EP 0 261 266 A1 a known bar lock for mounting in a hole in a wall thin, see eg Fig. 23, which comprises a head part in the form of a cavity of the actuation lever, a part of the body that comes out of the head part and that after assembly crosses the hole, formed by a locked lock box by screws in the head part, in which they are formed or supported clamping surfaces that after assembly are attached to the inner edge of the hole of the thin wall, formed in this case by an edge of the lock box. The inconvenient it is in this case the arrangement of the screws that make it cumbersome the bar lock assembly, especially when it comes of a robot assembly.

The object of the invention is a refinement of the bar lock in the sense of enable mounting without screws.

This objective is solved by the fact that the body part (or head part) presents an element of subject that yields overcoming the force of a spring, which during the assembly is coupled with a support element that comes out of the part of head (or body part).

In this way the need to effect disappears Screw mounting.

On the contrary, it is possible to make the union by means of pressure interlocking devices or clips.

According to an improvement of the invention, the fasteners that yield overcoming the force of the spring they could represent plastic spring arms, injected with the same piece with the head part, which near or in its Free ends have a protrusion or an entree, which fits in an incoming or outgoing formed by the body part. A montage interlocking is much simpler than fixing by screws

The alternative consists of a form of embodiment in which the fasteners that give in overcoming spring force represent plastic spring arms injected from the same part with the body part, which near or at its end they have a protrusion or inlet that fits with a incoming or outgoing formed by the part of the head.

Another alternative is one in which fasteners located on the part of the body that yield beating the force of the dock are some cars housed in the direction parallel to the thin wall and they are scrollable overcoming the spring force, whose free end has a surface inclined to comfortably support the body part in a incoming or outgoing surface formed by an extension that It comes out of the head part and it goes through the hole.

In other embodiments the union between the part of the body and the part of the head is not done by head screws, as in the state of the art, but by interlocking elements.

Especially the support without play of the part of the body in an incoming or outgoing offers the advantage of allowing also the bar lock housing without clearance inside of the hole in the thin wall.

To facilitate the assembly of the two parts with each other it is convenient that the extension present at its end Free an entrance ramp for cars.

Switching from right to left is facilitated if the body part is made essentially symmetrical with with respect to a plane parallel to the wall.

In this case it is convenient that the part of the body is divided in the plane of symmetry, and the two parts present accommodation spaces for a pinion and for two bars of center perforated plate facing the opposite direction, for the pinion gear coupling.

Alternatively, the body part can also include a pinion that is divided in the plane of symmetry, in which case the body part has accommodation spaces for two parts of the pinion and for two symmetrical plate bars around its center line, oriented in the opposite direction, perforated in the center and / or laterally, for the coupling of pinion gear. In both cases there is also symmetry here.

The last two embodiments cited are they differ because in one of the cases the box of the lock and in the other case the pinion.

In the case of the split pinion it is convenient that the part of the body present in the plane of symmetry a wall that separate the two housing enclosures from the parts of the pinion, the which has a hole for the drive shaft of the parts of the pinion. This keeps the pinion assembly in place.  formed by the two parts of the pinion.

You get a construction especially favorable if the body part forms accommodation spaces symmetrical about the plane of symmetry for cars, and if it is provided a helical compression spring for each car that is supports on the one hand at an inner end of the space of accommodation for the pier and on the other hand on a surface of support for the spring formed by the car.

The support surface of the carriage for the dock could be formed by an edge of the hole in the car, which partially encloses the pier.

To pre-assemble the box of the lock it is convenient for both body parts to present centering projections / centering recesses facing each other yes.

As for the operation technique it is convenient that the fasteners can be locked in your clamping position by means of pin devices or similar. This avoids involuntary displacement or separation of the two halves of the lock case.

The meaning and movement of the elements of clamping should be parallel to the direction of movement of the bars, to avoid seizures.

It is especially convenient if the hole on the thin wall is an elongated rectangle, whose longitudinal axis  It is in the direction of the bars.

The bar lock can present a rotary lever operation, but alternatively also a quick handle drive or a drive using a socket wrench.

A fundamental advantage of the provision according to the invention is that the bar lock can be snap with the bars already preassembled in the part of head, for example in the cavity. The fasteners, which they are clips, therefore they do not rely on the edge of the clipping of sheet but penetrate holes in an arrangement created in The key plate. In this way, the key plate is attracted to a closer position. The step of the key plate that takes for example an o-ring, sits against the sheet of the door and the bar lock rests in a known way in the inner edge of the installation hole, and encloses the sheet of the door as in the state of the art. In this case I don't know you need a hood or part of the hood as in the state of the technique, since according to the invention a unit has been created that It consists of the lock box (one or two parts), the bars, the pinion (one or two pinions) whose unit can be joined with the plate of the key (head part) by a fitting process to Pressure.

As in the state of the art, they can be use all kinds of maneuvering elements imaginable here external, such as key plate, long or short, handles of knob and doorknob, as well as rotating levers.

If the fasteners used for Snap fit are made with a double T-shaped section, then the two halves of the bipartite wheel box can be held together by them, so you could do without riveted or screwed. On the outer half of the box of the Lock does not act any force. Even if you use one three-point locking tab, only force is exerted over the inner half of the lock case through the step of the drive that is screwed to the tongue.

Fig. 1A shows in a side view the bar lock 10 for mounting in a hole 12 of a wall thin 14, such as the door leaf of a sheet metal cabinet, comprising a head part 16 where the head part can be a flange, or as in Fig. 1A, a cavity 16 with a drive lever 18, or a short key plate 216 or a long key plate 116 (see Fig. 1C), with an edge area 22 covering the outer edge of the hole 20 of the thin wall 14, in addition to a body part 24 leaving the part of head 16, 116, 216, 316, 416 and that after assembly passes through the hole 12, such as the lock case, in which they go supported or formed holding surfaces 27 that after mounting are attached to the inner edge of the hole 28 of the wall thin 14, so that the inner edge areas and holes 22, 28 are enclosed and caught at least partially according to Fig. 1B, for example along the middle of the longitudinal extension of the two longest edges.

Instead of joining, as in the state of the technique, the head or cavity part 17 with the body part or lock box 24 by means of screws, in this case the body part or lock box 24 carries an element of clamping 30 that yields overcoming the force of the spring 32, which it engages with a support element 34 that comes out of the head part. In the embodiment shown in Figs. 1A, 1B and 1C, the fasteners 30 that yield overcoming the force of the spring they are 36 cars housed in the body part or box of locks 24 movable parallel to the thin wall 14 overcoming the force of the spring 32, which have an end free with a chamfered surface 38 to comfortably support the body part 24 on a protruding or incoming surface 40, whose incoming surface 40 or projection 140 (Fig. 10) is formed by an extension 42, 142, 442 leaving the head part 16, 316, through hole 12.

The advantage of this chamfered surface is in which the design can be adapted to different thicknesses of the sheet of door 14, as well as the various manufacturing tolerances. The lock box 24 will thus catch without slack the blade of the door 14 between it and cavity 16, and with it is attached to itself Same without slack.

In the embodiments represented in the Figure 1A, 1B, 1C, symmetrical fasteners 30 are found in the longitudinal direction of lock, and therefore they are confronted diametrically, because in this way you can achieve a particularly durable hold without seizure.

The extension 42, 142 presents at its end free an entry chamfer 44, whose entry chamfer 44 causes that when entering the lock case or body part 24, 124 between the two extensions 42, 142, the fasteners 30, 32 are pushed back overcoming the force of the spring 32 when introduced along the chamfer, which facilitates the mounting.

As it follows from all forms of embodiment, the body part is essentially made of symmetrical shape with respect to a plane of the wall 46. Other symmetry results around the central plane 48, so that the component It has double symmetry, which facilitates installation and allows Also change the right-left function. In the embodiment represented in Fig. 1A, 1B and 1C, the body part 24 is further divided by the plane of symmetry located parallel to the wall, and the two parts form spaces of housing for a pinion 50 and for two plate bars 52, 152 oriented in the opposite direction and perforated so centered for the pinion gear coupling 50. Preassembly can be performed  of the lock box 24, placing in one of the halves the bar 52 or bars 52, 152 as well as pinion 50, placing then over the second half of the lock case and joining it with the first half of the lock case, for example riveting it, or by means of clips or fasteners 36 with double T section, see Fig. 7B. Lock case pre-assembled in this way can then be fixed using clips on the support elements 42, 142, introducing these through of the hole in the wall 12, the lock of bars.

Instead of mounting the base lock box of two halves, there is also the possibility of choosing a form of embodiment in which the body part 124 comprises a pinion 150, which is divided by the plane of symmetry 25, providing the body part of housing enclosures for both parts 27 of pinion 150 and for one or two symmetric 252 plate bars around its center line, oriented in the opposite direction and perforated by the center and / or by the sides, for the coupling of pinion gear 150, see Fig. 12, where the Sprocket assembly split into 150 in Fig. 12 and in Fig. 11, 11B, as well as the corresponding bar e Fig. 14. On the single-piece pinion 50 according to Fig. 9A, 9B, are the side walls 54 of the two halves of the box lock 56, see Fig. 8A and 8B, which deal with the axial driving of the pinion 50. In the embodiment according to the Fig. 12 is instead a wall 60 that divides the two enclosures of housing 58, 158 for the two parts of pinion 27 of pinion 150, which has a hole for a drive shaft 162.

The body part or lock box 24, 124 also has symmetrical housing enclosures 62 with respect to the plane of symmetry 25 for the carriages 36, 136 and for a helical compression spring 132 provided for each of the carriages. The helical compression spring 32, 132 is supported on one hand at an inner end 68 of housing 64 for the spring, and on the other hand on a seating surface 66 formed by the carriage, see Fig. 7A and 7B. This seating surface 66 of the carriage 36 for the spring 32 is formed by one of the edges of a hole 70 in the carriage, which partially surrounds the spring 32. The fasteners according to Figs. 7A and 7B are in section in shape in double T, as shown in Fig. 7B, which results in the fact that after inserting the fasteners into the two halves of the lock case it is prevented that the halves of the lock case can be separated, in the extent to which the enclosure 62 for the carriages also has the corresponding removed surface 72, as can be seen in Fig. 8C, in which the head of the double T shape of the element of
clamping 36.

To align the two halves of the box with each other lock 56 and prevent them from moving in pre-assembled state, the two parts of the body have centering protrusions 74 facing each other, which in this case are shaped like spikes or centering recesses 76, in this case in the form of a hole. Blind holes 78 can also be recognized in Figs. 7A and 7B in which, if necessary, a tool can be introduced to push the fasteners back to their position of decoupling Alternatively this blind hole 78 can also serve to block the fastener by means of a pin, so that after mounting the lock you cannot Go back by yourself.

The key plate can be shaped known a groove 80 for an o-ring.

The clamping surfaces 26 form according to the Fig. 13 covering profiles 82 that not only form the clamping surfaces 26 but also serve for the lateral guidance of the lock case or body part 24 with relation to the head piece or cavity 16. This form of embodiment is recognized in Fig. 4, and Fig. 5 shows that without This profile is also possible to achieve stable driving, in in which case the lock will have a lower height.

The way the device is held drive on the head piece is important here high school. For example there may be a step 84 in the part of head 216 that holds the drive with a square 86, at just as at the other end of the tree it can be complemented with a knocker tongue 68.

Fig. 6A, 6B and 6C show in different views of a head or key plate part with the surface of entry 44 already mentioned, also with a hitch contour or fixing 92 for a pre-assembled bar lock, for example mounted on the halves according to Fig. 8A and 8B, presenting these halves a few notches 90 for the hitch with the plate or with the rotating handle element.

Fig. 13 shows a front view of a box lock 124 in one piece, in which the bipartisan pinion 150 is preassembled. The halves of pinion 27 of pinion 150 are can be rigidly coupled to the torsion by means of a crown outline 94, and has a square hole 95. With a double pinion of this class can be combined various drives, for example drive mandrel 96 preassembled depicted in Fig. 12, which is attached to the pinion with its head screw 98.

The design according to Fig. 12 can be preassembled with the bars, for which the bars are positioned with their serrated 100 uncovered in the lock box 124 of a single piece, then the two parts of the pinion 150 can slide in axial direction from both sides on the teeth of the bar, to fix them next by screw and pin.

Now it can be inserted in the lock box the closed (perforated) area 101 of the bar 152 teeth.

The two open teeth 100 are needed by Therefore only for assembly.

In Fig. 15A, 15B a shape is represented of embodiment in which the fastener 436 is not symmetrical as in the embodiments according to Figs. 1 to 13, but in this case the clamping element 436 is provided with an entrance ramp 441 that makes the element of asymmetric subjection. This has the advantage that you don't have to make the ramp input at extension 442 of head part 460, which shorten the height of construction. You can also turn around to the lock box or to the body part 424 allowing this mode optionally right or left operation. For this purpose, the clamping element 436 can be inserted alternatively, so that the inclined surface 438 is always in direction towards the edge 440 of the extension 442.

Thus, for example, the element can be disassembled of the body 424 of the head element 416 by a hole or a recess 78 in the clamping element 436 to be able to take out later also the fasteners 436 of the body part and turn them over, so that you also have the possibility of subsequently change from right to left.

The stability of the assembly can be increased if the head part 416 with its extensions 442 and the part of the body 424 are nested together when fitted. This could achieved for example by a profile 73 formed by the part of the body, behind which the legs or extensions are placed 436 supported with their profiles 75, see Fig. 15A and Fig. 17 or Fig. 18.

This mutual nesting or mutual support prevents by example that extension 434 bends outward due to the pressure of the inclined surface 438 of the clamping element 440, when the clips fit.

Fig. 20A to 20C show_ {} in three views different another embodiment of a bar lock 510, where nesting is still marked more intensely than in the embodiment described above according to Fig. 15 a Fig. 19. Thus, the head part 516 shows an extension 542 that descends to the bottom with a wall 577 that at its free end form a support profile 575, to rely on a 573 recess, formed by a groove 579 of the body part 524.

Slot 579 and incoming 573 house so both the edge 577 with the hook 575 and they support each other mutually.

This way you can stay safely and without yielding the housing surface 540 to the surface inclined 538 of the fastener 536 shown in Fig. 21A and 21B.

The body part 524 is formed in this case for two halves, recognizing the first half in three views in Fig. 23A, 23B and 23C.

In Fig. 23C you can see by way of example in the middle of the lock box 556 the housing enclosures 557, 559 for the locking bars.

Also here is a fastener with double T-shaped section, see Fig. 21B, which serves to hold the two halves of the lock together.

Also here the clamping element 536 has an inclined surface 540 which is intended as an aid to assembly to facilitate insertion when mounting the case lock on the head part, which however does asymmetric clamping element 536, so that here too a measure is planned to be able to disassemble again the lock box to change the position of the elements of clamping, for which an inlet 561 is used in which one could insert a tool or similar such as a screwdriver, to through a slot 563 in the lock box 524 to release the fastener and pull the lock case out of the part head

Fig. 24A, 24B, 24C, 24D, 24E, 24F, 24G, 24H and 24I show for clarity different views partially sectioned and partially in perspective of the embodiment according to Fig. 20A to 23B, while Fig. 25 is a exploded perspective representation of that form of realization. The pieces that correspond to each other carry both also the same reference figures.

In Figs. 25A to 25F a embodiment that differs from the way of embodiment of Fig. 24A to 24F by the fact that the mandrel of drive is different. It has also been shown in Fig. 25G the corresponding hole 12 for the lock case 656.

The embodiment shown in Fig. 26A to 29B is suitable for actuation by means of a mandrel, indicated in Fig. 26A, and for actuation by means of a rotating lever, see Fig. 29A. The fixing hook 17 which here has a special shape And holds the cavity 716 in a manner similar to that shown in Fig. 1B in the cutout of the sheet 13 at the bottom. The plug-in cap 715 shown in Figs. 29A and 29B only has to compress the gasket 781 against the door leaf 14, which is represented in section in Fig. 29A and which adapts as a molded part to the shape of the cap. . Possible clip surfaces acting in conjunction with the corresponding knurling of the clip surfaces 785 of the
cavity.

Pinion 750 according to Fig. 29A moves the bars closing 52, 152 and in turn is actuated by means of a mandrel square with a lever 718. Using a tree lock 719 you you can pre-assemble the handle 718 in the cavity 716

According to Fig. 26A, a drive is provided by means of a socket wrench 796, for example in the form of square, or as handle operation, represented always with dashed line.

The two halves of the lock box 724, of which one is represented in Fig. 28A and 28B, can be snap into each other using spring elements 723, which they stay with clips in the corresponding 729 housings, for which the springs of the extensions 723 grab at the edges of back clamp 731 and press the two halves together to form a lock box 724. The lock box 724 formed of this mode has accommodation 733 for cars 736 and accommodation 735 for the corresponding dock 732. Similar to what is already described for other embodiments, of the head part or from the cavity 716 there are some supporting elements 734 with a ramp entry 744, which when placing the lock box 724 on the supporting elements 734 of cavity 716 push outward the cars 736. In this way the spring 732 is tensioned, which then when positioning the lock box 724 on the support element 734 penetrates the through hole with the Retaining surface 740 and is locked there.

For the assembly of the cars, a finger grip 734 by which you can take out the car 736 thus arriving at the release position.

The head part 716 can carry a centering extension 739 to center the head part 716 in the hole in the wall 12. Turning the lock box 724 back, see Fig. 26B, the embodiment of left to right.

The lock box 724 according to Fig. 29A it has a recess 741 in which an extension can penetrate 739 protruding from sheet 14 to center the box in this way lock

In principle, a form of embodiment in which the lock box is not two-part, such as described here, but as a single part, eventually With the pinion divided.

Also in the embodiment represented in Fig. 30A to 30E the box can be separated again 824 key plate lock attached with a clip or part of body 816, by means of key operation. The keys of pressure 837 according to Fig. 30A to 30D is simply placed before 824 lock box assembly and have their internal movement limited, but when operating the 836 clip elements, which here is not they carry out a linear movement but a turning movement, they they can push back to the position of release.

The four rivets 821 shown in Fig. 30E can also be replaced by rectangular clips for hold the halves of the lock box together, when they they are made of a suitable elastic material such as polyamide PA.

The clamping element 836 with the spring 832 is tilted about an axis 11 arranged separated from the plane of the wall surface and parallel to it, and carries at its end an ascending curve 13 whereby the clamping element 837 is placed in the final position behind a rear clamping surface 45, as already recognized in Fig. 30C. In this position, component 824 can no longer be separate from component 816. At the same time it is caught between them the door plate 14, and at the same time the fitting on the door leaf centering it as it has already been described

Only when the two push buttons are pressed pressure from both sides 837 reach their release position the support elements 836, so that you can then disassemble the 810 bar lock.

Fig. 30D shows otherwise in addition to the folded door leaf 14 a door frame 114, forming both a folded area in which the compact lock can be housed 824. The key plate 816 may be provided for keys of plug, L-shaped or D-shaped knobs as well as for lever.
