Description

The present invention relates to a locking pin for fittings of windows, doors or the like with a foot portion for arranging the locking pin on a sliding drive rod of a respective fitting and a head portion for locking engagement in a fitting associated with the closure member in response to a respective position of the drive rod.

Such a closure pin may be formed, for example, in the manner of a bolt, which extends perpendicularly from an example, flat and elongated drive rod. In particular, such a drive rod can be received in a groove of a fold of a wing of a window or a door, so that the lock pin can be selectively brought into engagement with a arranged on a frame of the window or the door closure member when moving the drive rod to the window or to lock the door or release it for opening. In principle, however, the drive rod with the locking pin on the frame and the closing part on the wing can also be provided vice versa. Furthermore, such a closure pin is in principle also suitable for use in a fitting arrangement in which the closure pin is fixed in a fixed position on a fitting part and instead the closure part is movable relative to the closure pin.

The foot of the locking pin is used in particular to connect the locking pin firmly with the drive rod. This can be done for example by riveting. In this case, the foot part usually extends along a Fußteilachse and is designed in the manner of a bolt. Thus, a locking pin, which is riveted on such a foot part on a drive rod, are rotated by applying sufficient torques against the frictional connection of the riveted joint about the Fußteilachse. This is useful, for example, when a headboard axis, along which the head part extends, is eccentric with respect to the foot part axis, ie offset in parallel. By turning the locking pin about the Fußteilachse then namely the head part can be offset laterally to the longitudinal extent of the drive rod to adjust a locking pressure of the wing against the frame of the window or the door.

In order for the head part of the locking pin to engage in locking the window or the door in the closing part, the closing part typically has an elongated receptacle into which the locking pin can be inserted perpendicular to the head part axis and in particular parallel to a longitudinal extent of the drive rod during displacement of the drive rod , In this case, the length of the head part must be dimensioned so that the head part of the drive rod over the distance between the wing and the frame, i. over the so-called "folding air", away to the closing part and a little way into this extends. Because if the head part is too short, it can not engage in the closing part and thus not lock the wing. If it is too long, for example, it hits the frame and may cause damage or prevent the sash from closing.

To increase the safety of the engagement of the locking pin in the closing part, it is known to form the head part as a mushroom pin, which has a circumferential diameter increase at the end remote from the foot part of the head part. The inclusion of the closing part is then designed so that the mushroom head can be inserted laterally, ie in the direction of movement of the drive rod into the receptacle, but can not be moved perpendicular thereto from the closing part, because the receptacle forms an undercut for the mushroom head. Such a design prevents the closure pin from being moved out of the closing part in the axial direction without actuation of the drive rod, that is to say, for example, during a break-in attempt by prying.

Particularly in the case of a design of a closure pin as a mushroom head, the correct length adjustment of the head part is particularly important so that the circumferential diameter increase during lateral insertion into the receptacle of the closing part is accurately guided behind the undercut, instead of hitting the undercut and thereby interfering with the closing part to be prevented.

It is therefore advantageous if the locking pin is adjustable in length. This can be achieved, for example, in that the head part of the closure pin comprises an inner pin extending away from the foot part along a head piece axis and a sleeve which is movably mounted on or relative to the inner pin so as to be movable axially with respect to the head piece axis To allow adjusting the axial length of the head part for a precise engagement in the respective closing part. For this purpose, the sleeve, for example, axially between two limit positions, namely a minimum position and a maximum position, by which a minimum or maximum length of the head part is defined to be free to move. In addition, the sleeve, in particular provided for the formation of a mushroom head circumferential diameter increase on the sleeve, and / or the receptacle of the closing part can be shaped so that when the sleeve meets the entrance of the recording of the closing part, automatically in the correct Position is shifted. For this purpose, for example, be provided on the sleeve or the closure member acting as insertion aids bevels, ramps or other guides.

However, when such free length adjustable stoppers are disposed on horizontal uprights of a wing or frame, gravity causes the stub to always be adjusted to its minimum or maximum length when it is not engaged with the closure member so that the head portion at each Locking newly drawn or pushed together and is reversed when opening again. This can result in increased wear of the sleeve and / or the inner pin. In addition, it may be that the automatic displacement of the sleeve caused by the interaction with the closing part is perceived by a user of the window or the door, in particular acoustically, as perceived as disturbing.

As an alternative to such an independent length adjustment to the respective folding air are known, which are manually adjustable to a certain length. Thus, these stoppers can be fixed to a suitable length when installing a wing in a frame. However, as the frame "settles" over time due to its own weight, i. E. With its end remote from the ribbon a little lower with time, is in such a closure pin lack of automatic length adjustment, an adjustment of the length of the locking pin required to ensure the unimpeded engagement of the locking pin in the closing part permanently.

It is therefore an object of the invention to provide a locking pin having an automatic length adjustment with ease of use with reduced wear.

The object is achieved by a closure pin having the features of claim 1 and in particular by being provided on the head part holding means for holding the sleeve in a defined axial position. The sleeve of this locking pin is thus basically free at least between two limit positions (minimum or maximum length of the locking pin), in particular infinitely, axially movably mounted on the inner journal of the head part, but can in a defined axial position, ie a certain position from between the two limit positions possible positions, are held by means of holding means. The retaining means may (despite the use of this term in the plural) be a single, for example, only on the sleeve or only on the inner pin provided, element or a device of a plurality of elements. In principle, the holding means may be designed to hold the sleeve in the defined axial position only temporarily, for example in accordance with a respective actuation of the holding means. In general, however, it is preferred if the holding means acts essentially permanently on the sleeve.

The said defined axial position may be a position that is individually specified by a user, for example by the user making a setting on the holding means. However, the defined axial position can also be defined automatically, for example by the described automatic adjustment of the axial length of the head part to the respective folding air. In this case, in particular, the defined axial position can change over time. In principle, however, the defined axial position can also be a predetermined and / or unchangeable basic or neutral position of the sleeve, in which the sleeve is e.g. is arranged substantially centrally between the two mentioned limit positions.

Such a closure pin can thus be offset automatically on the one hand due to its axial mobility, in particular by cooperation with the closing part, to a suitable length of the head part. On the other hand, it is, at least after the closure pin is again led out of the closing part, held in this or another defined axial position by means of the holding means. For this purpose, the holding means can be activated, for example, only by the engagement of the closure pin in the closing part or only when leaving the closing part for holding the sleeve. Preferably, however, the holding means are permanently effective, so that it is preferred if the holding means are designed to hold the sleeve in the defined axial position, that an, in particular automatic, adjusting the axial length of the head part at least in one direction, preferably one way both ways possible.

The retaining means should therefore not prevent or hinder the automatic adaptability of the length of the locking pin to the respective folding air. Rather, this automatic adaptability should be maintained and only the wear minimized. For this purpose, the sleeve by means of the holding means can be held straight in that axial position, which corresponds to the respectively suitable for a precise insertion into the closing part length of the locking pin. Or the holding means hold the sleeve in an adjustable, for example, central position, from which only a slight automatic length adjustment is required. Thus, the sleeve when locking and not releasing the respective wing at all or relatively little moves relative to the inner pin, so that sleeve and inner pin are less stressed.

According to an advantageous embodiment, the holding means are designed so that the defined axial position in which they hold the sleeve is adjustable. The adjustment is carried out in particular without tools and preferably by simply pulling or pushing the sleeve in the axial direction in that position, which should be the new defined axial position in which the sleeve is to be kept from now on. However, the adjustment may also be made by, for example, adjusting a characteristic of the holding means, e.g. a spring constant, a contact pressure or a spatial orientation to be made.

Furthermore, it is preferred if the holding means are designed to hold the sleeve due to static friction in the defined position. The static friction is preferably designed such that the sleeve can be offset axially by hand relative to the inner pin, but at least that the sleeve can be axially displaced in cooperation with a respective closing part for said automatic length adjustment, whereas displacement prevents only due to gravity becomes. The static friction has the consequence that the sleeve is simply held in each axial position in which it was last added, but that the sleeve otherwise unimpaired by overcoming the static friction forces continues to be freely and in particular steplessly axially adjustable between said limit positions.

According to a preferred development, the retaining means comprise clamping tongues formed on the sleeve, which are adapted to exert radial pressure on the inner journal. In this way, a properly acting and suitable measures between the sleeve and the inner pin static friction can be achieved. For example, the sleeve may have an inner diameter that substantially corresponds to the outer diameter of the inner pin and with which the sleeve rests against the outer diameter of the inner pin. In this case, the clamping straps may be formed on the sleeve so that they would assume a substantially force-free rest position in a detached from the inner sleeve sleeve, in which they protrude into the region of the inner diameter of the sleeve. However, if the sleeve is placed on the inner pin, press the clamping plates radially on the inner pin and thus increase the static friction between the sleeve and the inner pin.

Preferably, the sleeve has at least partially on a cylinder shell mold, wherein the clamping straps are formed by recesses in the manner of incisions in the cylinder jacket mold. The clamping straps can thus be produced in a simple manner in that the cylinder jacket-shaped sleeve is slotted from an axial end, in particular regularly in the circumferential direction. The areas between these cuts then form the clamping tabs. To generate a suitable contact pressure for the static friction, the sleeve in the region of the clamping straps, approximately at axial ends of the clamping straps, radially inwardly projections or other types (continuous or interrupted circumferential) diameter reduction.

According to an alternative embodiment, the holding means comprise at least one biasing device for biasing the sleeve into a neutral position. In such a biasing device is preferably a plate spring or other a comparatively small space requiring spring. The sleeve is thus held in this embodiment in a defined axial position, that it is biased in the neutral position. The neutral position thus corresponds to the defined axial position and is determined by the action of the at least one biasing device. The sleeve of the locking pin assumes the neutral position at least when no other significant forces acting on the sleeve, especially when the head portion of the locking pin just does not engage in an associated closing part. Nevertheless, it can be ensured, in particular by using a suitable spring hardness, that an automatic length adjustment of the head part of the closure pin is still possible, since the length adaptation can then take place against the bias. Due to the fact that the sleeve is held in said neutral position, which is arranged in particular at least substantially centrally between the limit positions of the axial movability of the sleeve, the distance by which the sleeve is displaced during the automatic adjustment is comparatively small and leads overall thus to a reduced wear.

For example, if the pretensioner is fixedly connected to the inner journal on the one hand and the sleeve on the other hand, a single biasing device may be sufficient to bias the sleeve from neutral to neutral in both axial directions, which then simply corresponds to the rest position of the pretensioner. If only a biasing device is provided which is not connected to both the sleeve and the inner pin or any other part of the closure pin, it may be that the sleeve is biased from one axial direction to the neutral position and in the other axial direction of the Neutral position up to one of the limit positions is freely movable. The biasing device can then be arranged, for example, in each case so that it biases the sleeve straight against gravity.

Alternatively, particularly when a respective biasing device is not fixedly connected to the sleeve and other part of the locking pin, it may be advantageous if the retaining means comprise two biasing devices which bias the sleeve in opposite directions in terms of their axial mobility. The neutral position then corresponds to a rest position of the system of both biasing devices. Displacement of the sleeve from the neutral position in one axial direction then acts against the bias of one biasing device and displacing in the other axial direction against the bias of the other biasing device.

Furthermore, it may be that the sleeve is biased only in respective edge regions of its axial mobility of a respective biasing device, but between a so-called bias-free axial region is formed in which the sleeve is not subject to any force of the biasing devices and thus axially substantially free to move , The said neutral position then covers this entire area. This applies both when only one and when a plurality of biasing devices are provided.

Furthermore, it is advantageous if at least one biasing device is adjustable with respect to its bias in order to change the respective neutral position by changing the bias. In principle, however, a single constant neutral position is sufficient to achieve the advantages essential to the invention.

According to a development, a respective biasing device between a formed on a circumferential collar of the inner pin abutment surface and formed on an inner peripheral reduction of the sleeve counter-abutment surface is effective. Alternatively or additionally, a respective further pretensioning device can be effective between a stop surface formed on a base plate, via which the foot part and the head part are connected to one another, and a counterstop surface formed on an end face of the sleeve. The abutment surface of the circumferential collar of the inner pin and the counter-abutment surface of the inner peripheral reduction of the sleeve in particular form mutual undercuts which lock the sleeve against detachment from the inner pin. As a result, they limit the axial mobility of the sleeve to a first limit position, in which the length of the locking pin is in particular maximum. As a transition between the head part and the foot part can also be a base plate, for example in the form of a flat perimeter extension with, for example, round or suitable for the application of a fork wrench cross-section, may be provided. By this base plate, the axial mobility of the sleeve can be limited in the opposite direction to a second limit position, which corresponds to a minimum length of the locking pin. It is therefore advantageous to provide respective biasing devices just between these for a limitation of the axial mobility of the sleeve optionally provided stop surfaces and counter-stop surfaces.

According to an alternative embodiment, the holding means comprise a spacer element, which is designed to limit the axial mobility of the sleeve to a maximum position or minimum position, by which a maximum or minimum length of the head part is defined, wherein, in particular by an adjustment of the spacer, different maximum positions or minimum positions are adjustable. Each set maximum position or minimum position thus corresponds to the defined axial position in which the sleeve is held by the spacer element. In this embodiment, the defined axial position is advantageously adjustable and is in particular defined by the fact that the axial mobility of the sleeve is limited in at least one direction by them. This can be effected, for example, by the spacing element forming a bearing surface as a stop for the sleeve at a specific distance from one of the two limit positions of the axial mobility of the sleeve. In particular, the mobility of the sleeve can be limited by the spacer in each case straight in that direction of movement, in which the sleeve is urged due to gravity. Thus, the spacer may serve to shorten the distance the sleeve passes between a locked position given by the closure member when the sash is locked and a limit position due to gravity outside the closure member so as to reduce wear.

According to an advantageous development, the spacer element has an inclined surface extending to the support surface, which cooperates with the sleeve to limit the mobility of the sleeve. Thus, depending on the respective position of the spacer element, the sleeve can cooperate with the bearing surface at a respective other point, in particular rest on the bearing surface or hit the bearing surface. Since the course of the support surface is inclined relative to the plane of movement, there are different support points or support areas of Support surface in different axial "heights" with respect to the headboard axis.

By adjusting the spacer within said plane, so axially different support points or support areas of the support surface can be selected to cause a limitation on the mobility of the sleeve. Consequently, this axial limit is adjustable by moving the spacer element, so that different maximum positions or minimum positions of the sleeve are adjustable. The course of the support surface can have a continuous and in particular constant axial height increase or decrease. In principle, however, the course may also be discontinuous, for example stepped, or have axial height increases or decreases of variable steepness.

For example, the spacer element is formed substantially as a wedge disk and is preferably movable within a plane perpendicular to the headboard axis level. As a wedge disk, therefore, the spacing element has a thickness that increases, for example, along a wedge axis, variably or preferably constantly. By means of a wedge disk, an adjustable stop for variably limiting the mobility of the sleeve can be implemented in a structurally particularly simple manner. Depending on the position and / or orientation of the wedge disk relative to the sleeve, the wedge disk can fill different and in particular different lengths of regions of the axial mobility of the sleeve and thereby limit the mobility of the sleeve in a respective direction to a maximum position or minimum position. As movements of the wedge disk, e.g. Translational movements, in particular in the direction of said wedge axis, or rotational movements within said plane in question.

In this case, the spacer element may be movably mounted approximately at a bearing portion of the closure pin. In particular, the spacer element is movable within a plane perpendicular to the headboard axis, for example by being translational within the plane, e.g. along an axis, displaceable or rotatable about an axis. According to a preferred embodiment, the spacer element is rotatably mounted about an eccentric adjustment axis to the head part axis. Although the adjustment axis is thus arranged parallel to the headboard axis, but offset from the headboard axis. In this case, the adjustment axis can coincide in particular with the said foot part axis of the foot part of the closure pin.

If the spacer element is a wedge disk, the wedge disk is preferably arranged with respect to its disk shape at least substantially perpendicular to the headpart axis. As a result, with a rotation of the wedge disk about the adjustment axis, the wedge disk remains unaltered perpendicular to the head part axis and the adjustment axis, but the thickness of the wedge disk projecting into the region of the head part axis eccentric to the rotation changes. This change in thickness due to the rotation of the wedge disk about the adjustment axis can be advantageously used to limit the mobility of the sleeve in a simple manner as desired to a respective defined axial position (maximum position or minimum position).

In order to secure the spacer in a set position, so to prevent unintentional adjustment of the defined axial position of the sleeve, securing means may further be provided which are manually operated or automatically block the spacer against displacement. The blocking may also be merely to stabilize the spacer element in a respective position by a certain mechanical resistance is opposed to a displacement of the spacer, which is to be overcome (without damaging respective securing means).

In this context, it is advantageous if between the spacer element and the bearing portion, a latching mechanism is effective to restrict the arrangement of the spacer relative to the bearing portion to a limited number of defined positions. In this embodiment, therefore, the mobility of the spacer is not infinitely, but determined by the interaction of the bearing portion with the spacer on transitions between some defined positions. The displacement of the spacer is therefore stepped due to the said locking mechanism. Thereby, the setting of the spacer element and thus the defined axial position of the sleeve can be limited to certain conditions that can be maintained particularly reliable due to the latching mechanism.

According to a preferred refinement, the spacer element engages with the inner circumference of a passage opening on an outer periphery of the bearing section, wherein respective profiles of the passage opening and of the bearing section are formed relative to one another in such a way that stable positions of the spacer element are defined and the spacer element from other, unstable positions in a respective one of the stable positions is urged. The spacer element is consequently not completely freely displaceable due to the interaction of said profiles. Rather, be characterized defines stable positions of the spacer element, in which the spacer element is advantageously urged, if it is not initially in such a stable position. Due to the stable positions is thus determined which positions the spacer element for adjusting the defined axial position of the sleeve can take longer in the long run. The other positions are so far unstable positions, as the spacer is exposed in these positions forces that urge it to one, in particular the nearest, stable position and preferably automatically put in this stable position.

For example, such a mechanism can be achieved with a spacer element rotatable about an adjustment axis in that the passage opening has a hexagon socket or another polygonal profile as the profile and the bearing section is at least substantially configured as an external hexagon or inner polygon corresponding external polygon, but at least one of the Profiles of this basic form deviates to some extent, in particular rounded corners and / or has curved edges. Such profiles then allow a relative rotational position of the spacer element to the bearing section in one of six or another number defined uniformly distributed (stable) positions, the positive connection between these profiles but is not accurate. The said deviations between the profiles are in particular such that, at least with sufficient elastic deformability of the passage opening and / or the bearing portion, a rotation of the spacer relative to the bearing portion against the actual positive connection is possible. But the profile of the bearing section and the profile of the passage opening are pressed against each other, unless a stable position is reached again. As a result of this force, the spacing element essentially inevitably snaps into the stable position at the end of a rotational movement.

Furthermore, it is advantageous if, in addition to the spacer element, the holding means comprise a pretensioning device for biasing the sleeve into the respective maximum position or minimum position. In such an embodiment, the sleeve is not only limited by the spacer in its axial mobility to a defined axial position, namely a maximum position or minimum position, but additionally biased in this position. The sleeve is thus still axially movable between the maximum position or minimum position and the opposite limit position, so that said automatic length adjustment of the locking pin is still possible. If the sleeve but not just cooperates with an associated closing part, it takes due to the bias of the maximum position or minimum position. This is done regardless of whether the mobility of the sleeve is limited to a maximum position or to a minimum position, as well as in which orientation with respect to the gravity of the locking pin is aligned, since the bias voltage optionally compensates for the influence of gravity. Thus, such a plug is particularly flexible at different locations of a wing or frame used to reduce the wear in a defined axial position adjustable and yet has an automatic length adjustment.

The object is further achieved by a fitting arrangement for a window, a door or the like, which comprises a drive rod and a closure pin arranged thereon according to one of the described embodiments or combinations of individual advantageous features thereof.

The invention will now be described by way of example only with reference to the figures.

1A and 1B show in a perspective view and a sectional view of an embodiment of a closure pin, the holding means are adapted to hold the sleeve due to static friction.

2A and 2 B show in a frontal and a perspective sectional view of an embodiment of a closure pin, the holding means comprise two biasing devices, which bias the sleeve in a defined axial position.

3A to 3C show in two sectional views and a perspective view of an embodiment of a closure pin, the holding means comprise a spacer element in the form of an eccentrically rotatable wedge disk.

The 1A and 1B . 2A and 2 B such as 3A to 3C show three different embodiments of a plug 11 , In this case, corresponding elements of the locking pin 11 each marked with the same reference character. The various embodiments have in common that the closure pin 11 one foot part each 13 in the form of a cylindrical bolt and a headboard 15 includes. The headboard 15 is essentially constructed in two parts and comprises an inner pin 17 and a movable on the inner pin 17 stored sleeve 19 , The inner pin 17 and the sleeve 19 are arranged concentrically to a headboard axis K, along which the headboard 15 extends and the parallel, but offset to a Fußteilachse F, the cylinder axis of the foot part 13 corresponds, is aligned.

The foot part 13 is at his from the headboard 15 formed end for riveting on a drive rod of a fitting, as in 2A and 2 B can be seen. In 3A and 3B the foot part is shown riveted state, wherein the drive rod is not shown.

According to the embodiments 1A and 1B such as 2A and 2 B is between the foot part 13 and the headboard 15 perpendicular to Fußteilachse F and the headboard axis K a disc-shaped base plate 21 formed, which has a substantially round cross-section, but at the straight portions are formed for applying a fork wrench.

At the of the foot part 13 pointing away end of the headboard 15 has the inner pin 17 in its end face an axial in the inner pin 17 penetrating intake 23 with hexalobular profile ("Torx") on. This recording 23 serves to make the locking pin 11 by means of a corresponding in the recording 23 engaging tool can be rotated about its Fußteilachse F relative to the drive rod, due to the eccentricity of the head part axis K with respect to the direction of movement of the drive rod lateral alignment of the head part 15 to adjust to adjust a locking pressure.

At the same end of the headboard 15 has the inner pin 17 also on its outer circumference a circumferential collar 25 on, the diameter widening of the inner pin 17 represents. The around the inner pin 17 around and with respect to the head part axis K axially slidably on the inner pin 17 guided sleeve 19 has an inner diameter that matches the outer diameter of the collar 25 in one of the foot part 13 pointing away area corresponds, in one to the foot part 13 on the other hand is reduced and there the outer diameter of the remaining inner pin 17 equivalent.

This inner circumference reduction 27 and the collar 25 engage each other, leaving the sleeve 19 insoluble on the inner pin 17 is stored. The axial mobility of the sleeve is due to the interaction of the collar 25 and inner circumference reduction 27 in the direction of the foot part 13 Limited to a limit position, the maximum length of the head part 15 or the locking pin 11 equivalent. In the opposite direction, the axial mobility of the sleeve is limited by the fact that it with the foot part 13 facing end face 29 to the base plate 21 or another at the transition between footboard 13 and headboard 15 trained stop strikes. This then represents another limit position, the minimum length of the head part 15 or the locking pin 11 equivalent.

The sleeve 19 has at its outer periphery to that of the foot part 13 removed end a circumferential extension 31 on, leaving the headboard 15 or the locking pin 11 is designed as a mushroom pin to increase the security of locking a window or door against a break-in attempt.

In the in the 1A and 1B illustrated embodiment has the sleeve formed substantially as a hollow cylinder 19 elongated recesses in the form of axially extending incisions 33 on, extending from the front 29 over at least about half of the axial extent of the sleeve 19 extend. This will be on the sleeve 19 in the areas between the incisions 33 clamping lugs 35 formed, which are slightly bendable due to a certain inherent elasticity in the radial direction.

The clamping straps 35 have at an inner pin 17 facing inside projections 37 due to the actual lack of space between the clamping straps 35 and the inner pin 17 because of the said inherent elasticity of the clamping straps 35 against the inner pin 17 to press. In 1B This is illustrated by way of illustration, as if the projections 37 in the inner pin 17 would be pressed in, which is not the case.

About the projections 37 is from the clamping straps 35 radial pressure on the inner pin 17 exerted, creating a stiction between the sleeve 19 and the inner pin 17 is increased at least so far that thereby the sleeve is held against the force of gravity or comparable minor force effects in a once occupied axial position. By manual axial adjustment of the sleeve 19 This axial position can be defined as desired. However, the axial position can also be defined by the fact that the sleeve is automatically adjusted in cooperation with an associated closing part (not shown) into a suitable for insertion into the closing part closure position and is then held by friction in these defined axial positions.

In the alternative embodiment according to 2A and 2 B the sleeve is held 19 by means of two biasing devices 39 formed as disc springs and between corresponding surfaces on the circumferential collar 25 and inner circumference reduction 27 or the base plate 21 and the front side 29 are arranged. The pretensioners 39 tighten the sleeve 19 in opposite direction, wherein in the neutral position of the sleeve shown 19 just lift the preload forces. Therefore, the sleeve 19 , at least as long as there are no other significant forces acting on them, from the pretensioners 39 held in this neutral position.

In contrast to the aforementioned embodiment according to 1A and 1B can the defined axial position in which the sleeve 19 is held in the embodiment according to 2A and 2 B not be easily adjusted. In principle, it is possible that the biasing devices 39 Such, for example, with respect to their spring force, are adjustable, that the neutral position can be changed. Another difference between the embodiments is that the biasing devices 39 the sleeve 19 when leaving an associated closing part does not hold in its closed position occupied in the closing part, but move back to the neutral position. As shown, this neutral position is preferably substantially in the middle between the two mentioned limit positions. This will remove the from the sleeve 19 maintained in the described automatic length adjustment distance on average comparatively low, since the distance in one direction corresponds at most to the distance between the neutral position and one of the limit positions.

In the further embodiment according to 3A to 3C is in place of the base plate 21 a spacer element 41 provided in the form of a wedge disk. As in the sectional views of 3A and 3B can be seen, the spacer element has 41 a central passage opening 43 on, the one around the transition between the foot part 13 and the headboard 15 of the locking pin 11 forming storage section 45 is stored. The storage section 45 and thus also the passage opening 43 are arranged concentric with the Fußteilachse F, to which the spacer element 41 is rotatable and therefore at the same time a setting axis E of the spacer 41 forms. The rotational mobility of the spacer element 41 is therefore eccentric to the head part axis K and in particular to the sleeve 19 , This can be used by turning the spacer 41 the sleeve 19 to hold axially in different minimum positions, as will be explained below.

In the in the 3A and 3C shown position of the spacer 41 is the area of greatest thickness, ie largest axial extent of the spacer 41 with respect to the adjustment axis E on the head part axis K diametrically opposite side, while the area of least thickness with respect to the adjustment axis E is aligned in the same direction as the head part axis K. In this position, the sleeve 19 as shown in a blind hole 47 protrude into the spacer element 41 is formed and has the same eccentricity to the adjustment axis E as the head part axis K in this position. The blind hole 47 is just so deep that it to the said area of the smallest thickness (in 3A and 3C left) almost flush with this area. In this in 3A shown position of the spacer 41 becomes the mobility of the sleeve 19 to one (namely the in 3A shown) minimum position of the sleeve 19 limited by the area of smallest thickness of the spacer element 41 is fixed.

Will the spacer element 41 rotated out of this position about the adjustment axis E, thereby the axially rising peripheral edge of the blind hole 47 under the front 29 the sleeve 19 pushes and raises the sleeve thereby. The front side 29 the sleeve 19 then lies as far as possible in their respective foot section 13 aligned position no longer at the bottom of the blind hole 47 but sets on a like a ramp acting support surface 49 extending from the area of least thickness around the edge of the blind hole 47 around to the area of greatest thickness of the spacer 41 extends. So that there is no jamming when the bearing surface 49 under the front 29 the sleeve 19 is urged, has the radially outer edge of the front side 29 also a chap 51 on. Depending on the position of the spacer 41 Consequently, a respective different contact area of the bearing surface acts 49 with the front side 29 the sleeve 19 together and limits the axial mobility of the sleeve 19 thereby to a different minimum position.

In 3B is the position of the spacer 41 shown in the sleeve 19 with her front side 29 at the axially "highest", ie from the foot part 13 most remote, possible contact area of the support surface 49 and thus in its mobility to another (namely the in 3C shown "maximum") minimum position is limited as in the 3A shown position of the spacer 41 one closer to the foot part 13 corresponding ("minimum") minimum position corresponds. Here is the spacer element 41 in 3B opposite to the 3A shown rotated position 180 degrees about the adjustment axis E. The region of greatest thickness is thus in the same direction with respect to the adjustment axis E as the head part axis K, while the region of least thickness of the spacer 41 this is aligned diametrically opposite.

Especially in 3C can be seen, has the passage opening 43 of the spacer element 41 the profile of a hexagon socket on. The profile of the bearing section 45 is accordingly designed as a hexagon, the corners are rounded, however. Thus, the spacer element 41 actually positively locked against rotation about the adjustment axis E. The passage opening 43 of the spacer element 41 However, it has sufficient elasticity to allow it to rotate. In this case, then, at least temporarily, the rounded corners of the profile of the bearing section 45 against respective edges of the profile of the through hole 43 pressed, whereby the edges are slightly deformed and exert a counter pressure on the respective corners. The pressure is only released when a stable position is reached again, ie a position in which again corner to corner and edge to edge come to lie, of which there are six due to the hexagonal profile. On the other hand, in other positions, which are unstable, the said pressure causes the spacer element 41 into the nearest stable position, so to speak. This will determine the possible alignment of the spacer element 41 at the storage section 45 limited to said six stable position, which are held at the same time very stable.

Even if the sleeve 19 in the figures always as at the spacer element 41 is shown resting, is the sleeve 19 not fixed to each that axial position in which they depending on the position of the spacer element 41 at the spacer 41 rests. Because starting from such of the position of the spacer element 41 dependent minimum positions (such as the two shown), the sleeve is still in from the foot part 13 direction away axially movable to an automatic length adjustment of the locking pin 11 to allow due to the interaction with an associated closing part. However, the sleeve is 19 by one of the pretensioners 39 the in 2A and 2 B embodiment shown comparable biasing device 39 biased in the direction of the respective minimum position. An axial movement of the sleeve 19 from their respective minimum position thus takes place against the bias of the biasing device 39 between the surrounding collar 25 of the inner journal 17 and inner circumference reduction 27 the sleeve 19 arranged and effective. As a result, on the one hand, the automatic length adjustment of the locking pin 11 not hindered, on the other hand, but still achieved that the sleeve, at least when it is not just cooperating with a closing part, is held in their respective minimum position.

Regardless of which of the ways described the sleeve 19 by holding means 35 . 37 . 39 . 41 is held in a respective defined axial position is in the three illustrated embodiments of a respective locking pin 11 each achieved that the locking pin 11 is easily adjustable in length with simple operation and thereby has a reduced wear.
