Releasable connecting device for two elements.

The invention relates to a device for releasably connecting two parts according to the preamble of claims 1-3.

Parts according to the invention are components that are intended to be paired in and then completely detached from each other. This includes, for example, doors and door frames, couplings of hoses, ropes, rods, etc., to be attached to walls or devices like., Wall panels, coatings etc.

The preamble of claim 1 similar devices are known in many different variations, such as a trunk or hood lock, or as connecting elements for two provided with aligned openings components, as described for example in German Offenlegungsschrift 3,511,070th In all these known systems, a one-hand operation is only during closure of the device possible, when dissolved, however, a second motion sequence is at least required, such as pulling on an opening lever in the vehicle or by pressing a pin or the like. (Compare DE-OS).

Although there are also devices and furniture fittings are known which are equipped with a toggle mechanism and so permit the opening and closing of doors merely by applying pressure. However, these devices are relatively complicated to manufacture and have a plurality of components.

There is also in crossing distances of the toggle an occasional strong crack noise, can be perceived as unpleasant as that in the bedroom area.

Moreover, you also know clamps with a spring-loaded locking element, for example. Ball catches that are simple to use in both directions, in the opening direction but hardly more resistance than offer in the closing direction. Most clearly the features of the preamble in U.S. Patent No. 3,039,802 are described. Two with a seat integral spring lips projecting at an angle to each other of the recording off and lock the displacer. When unlocking they are spread by the unlocking part, so that withdrawal of the displacement part and thus unlocking is possible. At the connection points of the spring lips to their base they are bent. It comes from there to a turn, what with frequent use to material weakening and consequently can even lead to fracture. When locked - in train on the closing pin - these connection points are equally loaded.

Finally shear the free ends of the spring lips both the displacer and on the unlocking sleeve, which can lead to material wear and unwanted abrasion.

An adjustment of the force of the bolt is very difficult, because at the same time increases the spring force at a gain of the material and a locking and unlocking more difficult. Other problems may arise from the leaf spring design that is opposed to the closing pin. To have sufficient resilience, namely this leaf spring must be relatively long and therefore be bulky. The total space requirement for the known device is thus considerably, so that an application for example in furniture hardly comes into question. Due to the cantilevered leaf spring, a lateral pressure on the lockbolt is also applied, which can lead to jamming. In two other fortified leaf springs may conversely come through a slightly wrong pushed Lockbolt a seitli chen Verdrehkippen the leaf spring, which then prevents the desired effect and may lead to undesired locking between the leaf spring and the displacement part. Such a lock can be released under certain circumstances only by destruction of the whole closure. An exchange or an adjustment of the known leaf spring alone is due to their connection to the base part also not possible. All these drawbacks have obviously led to the apparatus according to the US Patent in practice did not prevail.

The invention has as its object to provide a device which is produced in a simple, space-saving design with few components, while a secure closing, keeping closed solid and easy release allows, can be operated with one hand and has a long life. Moreover, the disadvantages of the known devices are to be avoided.

This object is solved by the features of the characteristics of claims 1 to 3rd The entire device according to the invention thus consists of only five components: A lockbolt, a sleeve-like release part, a resilient latch in a vertical position to the closing pin and a housing having a concentric spring whose force is directed against the lockbolt. The parts to be joined in the sense of the preamble of claim 1 are secured to the closing pin and the housing, so that both can be connected to each other. The invention thus provides a means for releasably connecting the one-handed operated, lockable and detachable, wherein automatically distanced from each other in solving the closing pin and the housing. A door opens, for example, after unlocking a piece of self-serving, as is also known in prior art toggle systems for furniture fittings. The concentric arrangement of the spring avoids oblique loads and disrupts not the function of the bar; Material wear are therefore low. The required penetration depth results from the alternative features in the characterizing part of claim 1, wherein the second alternative shorter overall build, but less elegant in the use is. However, the inventive effect in Einhandverschliessen or -open equals. Swinging in the normal plane is less harmful because only pivot forces, but not locking or clamping forces must be absorbed by the pivot joint.

A closing pin according to the invention is preferably a rotary member, but are for different applications, any other shapes in the invention lying. The decisive factor is the lockbolt only the presence of a shaft having a certain length extension - as explained below - for the mounting of the unlocking member or of the bolt. If the unlocking member mounted on the shaft, it also has a displacer or a Verdrängerkontur on, which is or a position the bolt - which is then mounted in the housing - to press during closing into its opening position, thereby the penetration of the to allow lockbolt and on the other hand must be locked with the bolt when the latter has come back under spring action back to its closed position. When the latch is mounted on the shaft, the displacement part can be omitted if equal a tapered contour can facilitate at its peak closing. The force which is required for locking or unlocking is, regardless of the holding force of the bolt. This is determined solely by the shape of the bolt itself. Used as a bolt, for example, a case, the cross section of the case determines the holding force of the bolt. The force that is needed there for locking or unlocking is mainly determined by the spring that pushes the case in the closing direction. This spring can be chosen arbitrarily strong or weak, without affecting the holding force.

As resilient bars are within the scope of the invention to understand all those individual or combined into groups components, the (vertical to the direction of lockbolt) are resiliently pressed in its closing direction, which can be pressed by a Verdrängerkontur into an open position and then automatically return to its closed position back. They can, as mentioned, be mounted in the housing or on the lockbolt.

As a sleeve-like release part for the purposes of the invention are understood as meaning all those components which are mounted slidably and captive either on the outside of the shank of the lockbolt or on the inside of the housing and having a Verdrängerkontur for the pushing back of the latch in its open position. In the variant with the handles of the closing pin the normal extension of Verdrängerkontur is the direction of movement at least equal, but preferably greater than the Verdrängerkontur of lockbolt.

The device indicated by the claims 1 to 3 thus knows 3 types of movement: - The pressing of lockbolt in the depth of penetration behind the bolt and thereby held locking with the housing; - The deeper penetration into the depth of penetration of the housing against the force of the spring and thus the opening or spreading apart of the latch by the unlocking and by the Verdrängerkontur of the unlocking; and - the subsequent retraction of lockbolt - supported by the force of the spring - in the unlocked position, the bolt - through the unlocking - can be counter-bearing to skip the closing pin or in the housing.

The claims 4 and 5 characterize or describe the inventive design of a device with the latch on closing pin, which is then selected when the closing pin should be designed as small and light (eg tool holders).

The channel ensures that the latch to release member upon retraction takes along to the stop, ie the (formed by the inwardly curled edge of the case) to the displacer. The connection between the bolt and this groove corresponds essential that of a conventional ball catch closure. An annular groove on the lockbolt ALLOWED the use of a relatively inexpensive spring ring as a bolt which can also be easily exchanged, is moment during a bore with fallenartigem bolt mainly in acylindrical lockbolt advantageous. By trough a secure closure un open in all directions with or against gravity is possible.

The Optional feature of claim 4 and the features described in the characteristic of claims 10 and 11 guarantee an absolutely safe release of the device as soon as the unlocking member has displaced the bars, wherein the normally provided on the Verdrängerkontur of lockbolt cam bevel with an entry bevel of the bolt automatically cooperates so that the closing pin is pushed out of the housing. In addition, the required path when unlocking is the smallest. When training with the handles of the closing pin opening cooperates with a bolt designed as Verdrängerkontur stop bevel on acting as displacer outer edge of the casing.

Another task is particularly important in the field of child safety doors: Even though there are locks to procure children in many cases key and thus forbidden access. This is to prevent it. The latter task is first solved by the features of claim 6 in a simple manner. Depending on the required power to overcome to release the device can be provided sufficiently strong springs. The adjustable or interchangeable springs allow the constant adaptation to the existing conditions (age), while a lock enables the permanent closing. As a barrier in the context of the invention non-elastic components are to be understood to be clamped parallel to the spring or disposed normal to the direction of movement of the lockbolt and with the displacement part thereof are engageable to prevent or to prevent retraction of the bolt whose motion.

As springs according to the invention any resilient material, such as conventional helical or rubber springs out of the question.

Further features and advantages are described in the characteristics of the further subclaims.

The features of claim 7 ensure easy interchangeability and easy mounting of the spring, while the features of claim 8 an optimal integrated solution, a particularly simple design and inexpensive spring material featuring.

The features of claim 9 enable easy and quick adjustment of the bias of the spring, so that it can be changed if necessary (visit by foreign children, for example, but also reduce the spring force in convalescence, the user etc).

The features of claims 12 and 13 illustrate different variants of design, which also guarantee the safe unlocking and thereby have an uncomplicated design. The arbitrarily operable linkage may occur for those special cases for applications where the release of the device is not to be achieved by printing directly on the closing pin.

The feature of claim 14 represents an optimum design for use in furniture, because the device only a little space is required.

The features of claim 15 featuring a quick release connector or with a hose or pipe system, as it can for example be used in Bewässungsanlagen or hydraulic systems.

Identical parts are provided with the same reference numerals, like parts with like reference numerals and different index. The figures are described across and coherently.

The essence of the invention consists of a female member 1 and a locking member 2, the latter of which has a closing pin 9, which according to the Figure 1, 2, 4, 6, 7, 9, 13, 16, 18, 19 and 21 to 27 is designed mushroom-shaped and a cylindrical shank and a - the cap of the mushroom accordingly - conically widened displacement part 12 comprises the (57 arrow) acts against the movement direction as pawl, is carried out as later.

Lockbolt 9 of Figures 33 to 36 is cylindrical without mushroom cap, he must carry out any displacement.

The lockbolt 9a in the Figure 3 and 8 is hook-shaped, wherein the protruding part of the hook forms the displacement part 12f.

The displacer 12 g in Figures 21 to 27 has, on its side facing the receiving part 1 opposite side a recess 59 for partially receiving an unlocking member 11d -. F, while the other Verdrängerteile 12 in this area is a flat face in a plane about 90<u>°</u> have from the axis 6 of lockbolt. 9

The displacement part 12e according to Figure 10 is as mushroom-shaped, but axially provided in the middle with a hole 14th All Verdrängerteile 12 have a Verdrängerkontur 13 formed in the substantially cone-shaped or cambered.

The Verdrängerkontur 13 serves in connecting the parts initially push back a bolt 5 to overcome it in the direction of movement (arrow 57) and to latch with him then. The Verdrängerkontur L3E; f and the displacement part L2i; k is not at the closing pin 9 but is on the housing 2n; m formed. The respective latch 5k and l are pressed by the contours 13e and f inwardly while latches 5a-i are always pressed by the contours 13a-d when locking to the outside.

The bolt 5 are analogous to the closing pin 9, the different training options, which are determined essentially by the occurring during the closing displacement operations and through to compound transferring forces between the two parts. The massive training of the bar is shown FIGURES 1 2 and 9 and 12th In these cases, the bolt 5a and 5b consists of three identical ring-segment-shaped elements, which is centered by a spring, or by a rubber ring 16 and against the axle 6 are held pressed. As a result of the strain elasticity of the spring and the rubber ring 16 of the bolt can thus be forced radially apart 5a and b and permit passage of the displacement part 12a and d. After the displacer 12a or happened d with its widest point (largest dimension perpendicular to the direction of movement), closes the latch 5a and b due to elastic force of the rubber ring 16 again. Of course, also possible to provide several or only two instead of three ring segments.

In cases where less forces need to be transferred, sufficient 5c simpler one-piece locking, as they are shown in Figure 3, 6 and 8. FIG. In these cases, the bolt 5c is a component of trapezoidal cross-section.

establish production Technically simplified and yet with a good force transmission ratio, the bolt 5d according to Figure 14 and 17. The bolt 5d consist essentially of an integral, annular leaf spring, which is cut in a star shape on its inner side and in which the cut segments 34 in an angle to the surface extension of the leaf spring are bent. The segments 34 permit by resiliently retreat a passage of the displacement part 12 in the direction of movement. Once this has happened, they go back to their original position and prevent such a release of the device. The bolt 5d is made as a separate component and can be used in the most varied constructions.

Another bolt 5e is illustrated in Figures 4, 10 and 11. FIG. The bolt 5e consists of an open conical spring ring which can be widened by the Verdrängerkontur 13 and resiliently returns to its initial position.

The bolt 5d and 5e have the advantage that they spring without additional spring elements and are simple to manufacture compared to the previously described bars. 5

All previously described versions of the bolt 5 have an entry bevel 7, the 12 allows a displacement of the bar in pressing the displacement part in closing or moving direction. This entrance slant 7 and the with it cooperating consequently Verdrängerkontur 13 are selected such that the friction between the two surfaces and minimal self-locking is prevented.

The weakest form of the bolt 5h results when this is formed from spring wire and with only two retaining lugs (69) for locking ensures. However, such training, as well as the variants of bars 5f, g, i, k which also consist of a bent spring wire at the most cost-effective, especially since they themselves lock both feathers. The entrance ramp is that they generally produce round training the wire cross section.

The third essential element of the invention is a release member 11, slidably disposed on the outer side 18 of the shank of the lockbolt 9 or at the Innfläche 71 of the housing 3m, n (Fig.33-36). The Entrieglungsteile 11a, b, and d to g in accordance with Figure 1; 4 and 2; 7; 9; 10 and 18 and 21 to 27 and 33 to 36 are cylindrical sleeves, while the unlocking part 11c is in accordance with the Figure 3 and 8, a cubic body having a bore for the shank of the lockbolt 9a. As well as the displacement part 12 are all variants of the unlocking parts 11 via a Verdrängerkontur 17 between the simplest case corresponding to the Figure 1, 2, 4, 6, 7, 9, 10, 16, 18, 19 and 36 of a rectangular merger of the displacement part 12 facing end face of the unlocking member 11 and the outer side is formed.

Preferably, the Verdrängerkontur 17a is rounded as seen from Figure 3 and 8. FIG. A sharp edge of Verdrängerkontur 17 could damage the entrance ramp at 7 of frequent actuation. A rounding reduces the friction between the inlet 7 and the bevel Verdrängerkontur 17 and thus facilitates the sealing of the device. A self-locking between the Verdrängerkontur 17 and the entrance ramp 7 is prevented.

similar to the displacement part 12 c tapered conical; In Figure 21 to 27 and 33 to 35 which are Verdrängerkonturen L7B. The unlocking parts 11d and e have a ridge 62 following the Verdrängerkontur 17b and c and an adjoining groove 60, and 60b, which preferably rounding of the wire of the bolt 5g, h and k einspricht. When unlocking the Verdrängerkontur penetrates 17b and c in the recess 59 and 59a of the displacement part 12g or I and after overcoming the width of the ridge 62 of the bolt 5g; h; k short in the groove 60, a 60b, so that it at eventual opening slightly biased over the ridge 60 and across the gap between the displacer 12 g, i, and the unlocking part 11d, e, g rockets. This design is the spring characteristics of the latch 5g, h, k worn optimal invoice. A special entry bevel is it no longer necessary.

The unlocking member 11 is pressed regardless of the closing pin 9c and 9e (Fig.2 bzw.Fig.7) or together with the closing pin 9 against the insertion bevel 7 of the bar 5, so this so long recedes radially outward until the point the largest dimension normal to the movement direction of the unlocking member 11 and the Verdrängerkontur 17 to the radially innermost surface 29 (Fig.6) of the bolt 5 is stuck. In this position, the bolt 5 is in its release position. Lockbolt 9 which slides in unlocking 11, can be withdrawn as far until it reaches with its displacement part 12 which faces this face of the unlocking 11th

Now, if the closing pin 9 further pulled outward, so does the displacement part 12 and the latch 5k; i (Fig.33-36) the unlocking part 11. In the embodiments according to Fig.1-32 the displacement part 12 moves the lock release member 11 from the clamping of the bolt 5. In the variants according to Fig 33-36 the displacer blocked L2i;. K removing the unlocking member 11g; h and the latch 5k; l is calculated from the clamping of the part 11g; h drawn once the unlocking has 11 leave the bolt 5, or vice versa, takes over the Verdängerteil 12 the clamping force of the bolt 5. As the displacement part 12 but has its conical or domed Verdrängerkontur 13, slips the bolt 5 - continued in closed position begebend - in direction of the axis 6 and thus displaces his turn the displacement part 12 and thus the closing pin 9 in the fully disengaged position.

For this always works reliably, the Erstrekkung (20) of the bolt 5 has in the direction of movement (arrow 57 in Figure 1) at most the game 19 of the unlocking 11 correspond to the direction of movement at the closing pin 9 (see Figure 3).

In addition, the extension 30b of the bolt 5 in the direction of movement in its the lockbolt is not 9 nearest area to be smaller than the minimum distance between the maximum normal extent (33 in Figure 8) of the Verdrängerkontur 17a and the unlocking member 11c on the moving direction and the greatest normal extension (31b in Figure 8) of the Verdrängerkontur 13a and the displacement part 12f on the direction of movement.

Finally, it is of course necessary that the normal to the direction of extension of the unlocking member 11 is at least as large as the largest normal extent of the displacement part 12. In the Figure 1, 2, 4, 9 and 10, the unlocking parts 11 having about the same outside diameter are as the Verdrängerteile 12 is shown, while the unlocking member comprises 11c shown in FIG. 3 and 8 has a slightly larger outer diameter than the displacement part 12f and on its side facing the displacement part 12f facing end surface 27, an undercut 28 having suitable, the displacement part 12f take in part. This causes the unlocking by pushing the unlocking member 11c against the insertion bevel 7b of the bolt 5c or by subsequent jamming of the bolt 5c at Verdrängerkontur 17a to an elegant removal of lockbolt 9a from its closed or LOCK th position. In such an arrangement the bolt can be designed particularly narrow 5c (viewed in the direction of lockbolt).

In all variants, there is a spring which is exemplified in FIGURES 1 through 18, and 23,30, 31, and 36th The spring 10 is the insertion of lockbolt 9 or at least the insertion of the unlocking member 11 against a resilient resistance.

In FIGURES 1 and 18, while a spring 10b is shown, which is mounted on a pressure plate 8 which is mounted on the shank of the lockbolt 9d and projects radially beyond these. The spring 10b is made of a sleeve-shaped including: formed foamed elastomer and arranged concentrically to the shank of the lockbolt 9d. In this case, it is adhered to the displacement part 12d the end surface facing the pressure plate eighth

The spring 10b can see Fig.5, replaced at any time by a spring with a different spring characteristic, but about the same dimensions as needed (10d 10c). This allows different stiffness settings are achieved, impede or facilitate the closing or releasing the device.

At which the pressure plate 8 side facing away from the spring 10b is supported in the closed state on the housing outer wall 35 of a housing 3a, which has the bolt 5a and a bore 4 for the lockbolt or 9d whose displacement part 12a.

In the variant of Figure 18, the spring 10b is supported on its side facing away from the pressure plate 8 side and the borders of a hole in a door 36a. In this application, the spring is attached to both the pressure plate 8 and at the door 36a, glued example, thus keeping the closing pin 9e captively. The hole in the door 36a is so wide that the unlocking part 11f is also received therein and is not hindered in its sliding movement on the stem of lockbolt 9i. Seaming or the release movement is thus performed in the variant according to Figure 18 by direct pressure on the pressure plate 8, while in the variant of Figure 1 in the case of a door lock, the pressure plate 8 is fixed to or integrated on the inner side of a door and the closing or releasing thus takes place by pressure on the door itself. Such a variant is indicated in Figure 16 at the door 36b.

The housing 3a in the case of the Fig.15 and 16 in Tuers integrated tock 37th A reverse arrangement in which the closing pin attached to the door frame and the housing is accommodated in the door, is of course also possible in special cases. In both cases, may be dispensed with a pressure plate 8, when the displacement part 12 remote from the end 38 of the shaft 9b is formed, for example, as a screw, as shown in FIG. 16 indicated. In such a case, however, the attachment of a sleeve-like spring 10b is unfavorable, so that one of the spring variants described in the following shall apply.

In figures 2 to 4, 6, 9-13, 15, 16, 23, 33 and 36, the spring force is formed by a lying in the interior of the housing 3 spring 10 as a helical spring (10a in Figure 4; 10g in formed 36); Figure 2), sleeve-shaped foam Eder (10c in Figure 6) or block-shaped foam Eder (10h; l in Figure 3; 33rd In Figure 2 further comprises a cylindrical foam Eder 10f is shown which is used to enhance the spring force of the coil spring 10g in this.

All springs 10 may be interchangeable, or as shown in Figure 2 can be reinforced. In Figures 4, 6 and 23, however, preferred variants are depicted in which the spring force by an adjustment screw 25 and an adjustment eccentric 26 is adjustable.

The adjustment is made by turning a knob 39 which is connected via a shaft 40 with an eccentric cam 41 (Figure 6), or as a screw 42 is formed and screwed in the housing 3c in a thread. Both the eccentric cam 41 and the screw 42 act on an abutment 24a; b; c for the spring 10c; a; l. In Figure 4; 33 another abutment 43; shown 43a on which the abutment 24b; l is provided, and the transition between the displacer 12 and the closing pin and the spring 10a;; c remote end of the spring 10a forms l ,

Another adjustment of the spring force results particularly advantageous in the embodiment of FIG. 30 and 31, since they can be carried out there with a screwdriver 68 from the side of the locking member 2 ago. A screw 42a, sporting the rubber composite plate 66a made of metal, on which the spring 10k glued rubber. At the other end of the spring 10k as sticking a rubber composite plate 66b, in which a screw slot 67 or a cross hole slot is formed. The screw 42a is screwed 3k adjustable in a thread in the housing.

In Figure 7 a variant is shown, in which the lockbolt is divided 9e and 9f into two parts. The parts of lockbolt 9e and 9f are connected inseparably 10e at their separation points with a pen. The unlocking part 11e bridged both parts 9e and 9f. The portion 9e which carries the displacement part 12c, is thus permanently connected to the part 9f, which in turn carries the printing plate. 8 When releasing the device, the pressure plate 8, as already described above, pressurized, whereupon 10e against the force of the spring, the distance between the two Tei len 9e and 9f is reduced so that the unlocking part 11e toward the entry ramp is not shown the will latch pushed.

In Figure 10 a rubber gasket 44 is shown, which also has resilient action. The rubber seal 44 forms a transition between the pierced displacement part 12e and the housing 3g, which in turn is tightly connected to a hose 45th Since the pierced closing pin is 9h also connected tightly with a hose 46, an unmolested passage light between the hoses 45 and 46 results in the variant according to Figure 10 in the closed state. All the housing 3 shown in Fig.1-32 have suitable receptacles for receiving the latch 5 as well as for receiving the lockbolt 9, wherein it has a penetration depth 21 is necessary at least to the longitudinal extent of the displacement part 12f and the gap 19 of the unlocking must 11c correspond to the closing pin 9a (see Figure 3).

Now to the farther details in the embodiments: The variant according to Figure 1 has in its housing 3a has a radially projecting from the axis 6 to the outside slot 47 which receives a sliding barrier 22 with approximately rectangular cross section, with the aid of the penetration movement of lockbolt can be prevented. 9 The barrier 22 could also be connected with a lock, not shown, so that only have a suitable key operative persons access. Another barrier could also be provided in parallel with the spring 10b.

In the variant of Fig.2 the unlocking part 11b is connected to a linkage 15 which is guided in a bore of the shank of the lockbolt 9c axially thereof. In the region of the unlocking of the lockbolt 11b has 9c via a slot 48 in which two radially outwardly projecting parts of the rod 15 are displaced in the direction of movement. This outwardly projecting parts of the linkage 15 are rigidly connected to the unlocking 11th A pressure in the direction of movement (arrow 57) on the linkage 15 thus causes a displacement of the unlocking member 11b toward the entry slope 7a of the bolt 5a, and thus a release of the lock. This variant can be provided wherever it may lead to unwanted pressures on the closing pin so that accidental solutions could take place. In this case, however, a two-handed operation is required.

The housing 3c according to the variant of Figure 4 is a pressing part, which at its end facing the pressure plate 8 end has an edge 48 which 3c during the mounting of the receiving part 1, that is at the mounting of all parts in the housing is pressed inwards becomes. The original state is shown in phantom. By looking inward compression of the rim 48 a disc 49 is pressed against the 5e as a bolt formed spring ring, so that it is fixed permanently and captively in the housing 3c. Although the ring has a vertical game but is not disturbing due to the Verdrängerkonturen 13, 17th

For the installation of the receiving part 1 and the housing 3 in a door or a door frame can be provided at the periphery of the housing 3c a thread, so that the housing can be screwed.

See also Fig. 28 with the door frame 37 and a door 36b, in which a blind hole for the end 38 of the locking member 2 is provided. Can not be used in the door frame of the female member 1, a receiving sleeve 63 is provided according to FIG. 29, or the like which at its base surface 65 elongated holes 64 for bolting a door Stock. having. In such a receiving sleeve 63 any receiving pieces 1 can be used, preferably screwed. Optimally suited for a female member 1 according to FIG. 31.

The springs 10b to 10d according to Figure 5 are of the same material and to different extents (10b and 10c), or from a non-foamed elastomer, the wedge-shaped for controlling the spring characteristic comprises receiving rings (10d).

The spring 10c in the variant according to Figure 6 is held in the housing by retaining shoulders 3d 49 coaxially to the axis 6 of lockbolt 9b. The bolt 5c is held captive by a known and not shown measure in case 3d, so it is not lost after removal of lockbolt 9b. Towards the axis 6 it is held down by a coil spring 50th The Verdrängerkonturen 13c and 13d of the displacement part 12b and 12c in the 6 and 7 are in contrast to the other Verdrängerkonturen formed purely conical.

The variant according to Figure 9 and 11 is used for releasably closing two cable ends 51a and b, wherein the cable end 51a is brazed to the lockbolt 9g and the cable end 51b to the housing 3f. The unlocking part 11e has a conical handle bevel 52, the same one pressing against the bolt 5b easier. A similar handle slope 52b is formed on the lock member 11e at the hose coupling according to the variant in Figure 10.

The Figure 15 and 16 show schematically illustrated hinges 53 for supporting a door 36. An adjustment mechanism according to the 6 is indicated by the knob 39b. The receiving part 1 consists of the housing 3 and the bolt 5 and is sunk into the door Stock 37th

The stern illustrated in Figure 19 of a vehicle has a kick-off device 54, in which a receiving member 1 is integrated. With a closing pin 9g corresponding to Figure 9, it is thus in the simplest form possible, like to connect a tow rope or the impulse device 54th

Such Seilansteckvorrichtungen found in lorries to secure the goods application.

In Figure 13 a broom 55 is shown, which is held symbolically by means of an apparatus according to a ceiling 56th Of course, the variety of objects can be secured in such a way.

The unlocking piece 11c shown in FIG. 20 shows an auxiliary spring 58 which is clamped between the displacer 12 and the unlocking part 11c. This additional spring 58 thus provides 11c sure the initial position of the unlocking. The unlocking part 11c is so fundamentally in the displacer 12 remote location and is only pressed by exerting the desired release pressure on the closing pin 9 against the latch. 5 For better guidance of the auxiliary spring 58 of the unlocking part 11c has an unlocking the 9 facing concentric undercut which receives the additional spring 58th The housing 3h according to Fig.21 has a groove 61a on its outer side, which holds the latch 5f captive. The bolt 5f could thereby similar to the bolt 5h be formed by Fig. 24.

The housing 3i shown in FIG. 22 has a groove 61b on its inner side. The bolt 5g protrudes at zuminest two Stel len into this groove 61b and is thus held captive there. The remaining points of the groove 61b serve as a passing loop when locked or unlocked.

By depicted figures and the description, the invention is not limited. So may be provided, for example, instead of the rubber spring 16 and annular coil springs. For special applications, the bolt may be 5 itself is formed of a resilient material so that they permit the penetration of a lockbolt or dissolving them through the unlocking 11th

The limiting part of the housing 3i beside the groove 61b could also by crimping the rim done possibly to insert a shim to secure the freedom of movement of the bolt 5g.

To all the examples described so far, different construction of the devices of Fig.33-36 are, as already mentioned, technical solutions reversal of the principle described in the Fig.1-32. Latches 5k and 51 are held in a groove 60a or in a hole 74 on the closing pin 9m and 9n. This latch 5k; l lock in its closed position with a displacement part L2i; k, the 3m to the housing; n is formed. The operation and closure retention strength is identical to the other variants substantially. The bolt shown 5k, l are described only by way of example and the like could by any other, such as leaf springs, locking cam, detent balls. be formed.

In Fig.36 it can be seen as falling like latch 5l can be secured to prevent loss: The loss device 72 has substantially for each event type latch 5l a threaded bolt, which is screwed into the closing pin 9m, for example a screwdriver 68 and has a length, with which it engages in the bore 74 or in a slot-shaped recess 76 of the latch 5l. The latch 5l, although by a spring 77 in the closing direction and thus applied to the outside, but is prevented by the threaded bolt to a complete falling out of the hole 74th The latch 5l has a case-like approach ramp, so that the unlocking part 11h on its front page not beveled must be. A groove 60c on the inner circumferential surface 73 of the unlocking member 11h also serves here for tightening the bolt 5l, so that, or the closing pin 9n can pull the unlocking part 11h against the displacement part 12k.
