Definitions

  • the present invention relates to a locking pin for fittings of windows, doors or the like with a foot part for arranging the locking pin on a displaceable drive rod of a respective fitting and a head part for locking engagement in a locking part assigned to the fitting depending on a respective position of the drive rod, wherein the head part comprises an inner pin extending along a head part axis away from the foot part and a sleeve which is mounted movably axially in the direction of the head part axis in order to enable the axial length of the head part to be adjusted for a precise engagement in the respective locking part, and whereby the head part holding means for holding the sleeve in a defined axial position are provided.
  • Such a locking pin can, for example, be designed in the manner of a bolt which extends vertically from a drive rod which is, for example, flat and elongated.
  • a drive rod can be accommodated in a groove in a rebate of a sash of a window or a door, so that when the drive rod is moved, the locking pin can be selectively brought into engagement with a locking part arranged on a frame of the window or door in order to close the window or to lock the door or release it for opening.
  • the drive rod with the locking pin can also be provided on the frame and the locking part on the sash.
  • such a locking pin is in principle also suitable for use in a fitting arrangement in which the Locking pin is fixed in position on a fitting part and instead the locking part is movable relative to the locking pin.
  • the foot part of the locking pin serves in particular to firmly connect the locking pin to the drive rod. This can be done, for example, by riveting.
  • the foot part generally extends along a foot part axis and is designed in the manner of a bolt.
  • a locking pin which is riveted to a drive rod via such a foot part, can be rotated about the foot part axis by applying sufficient torque against the frictional engagement of the rivet connection. This is useful, for example, if a headboard axis, along which the headboard extends, is eccentric, i.e. offset parallel, with respect to the footboard axis.
  • the head part By rotating the locking pin about the foot part axis, the head part can then be offset laterally to the longitudinal extent of the drive rod in order to set a locking pressure of the sash against the frame of the window or door.
  • the locking 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 extension of the drive rod when moving the drive rod .
  • the length of the head part must be dimensioned such that the head part extends from the drive rod over the distance between the sash and the frame, ie over the so-called "rebate clearance", to the closing part and a little way into it. Because if the head part is too short, it cannot engage with the locking part and therefore cannot lock the sash. On the other hand, if it is too long, it will hit the frame and can cause damage or prevent the sash from closing.
  • the head part As a mushroom head pin, which has a circumferential increase in diameter at the end of the head part that is spaced from the foot part.
  • the receptacle of the locking part is then designed in such a way that the mushroom head can be inserted into the receptacle laterally, i.e. in the direction of movement of the drive rod, but cannot be moved out of the locking part perpendicularly thereto because the receptacle forms an undercut for the mushroom head.
  • Such a design prevents the locking pin from being moved out of the locking part in the axial direction without actuating the drive rod, for example in the event of an attempt to break in by prying it open.
  • the correct length adjustment of the head part is particularly important so that the circumferential increase in diameter is guided precisely behind the undercut when inserted laterally into the receptacle of the locking part, instead of hitting the undercut and thereby engaging in the locking part to be prevented.
  • the locking pin is adjustable in length.
  • the head part of the locking pin comprises an inner pin extending along a head part axis away from the foot part and a sleeve which is mounted on or relative to the inner pin in an axially movable manner with respect to the head part axis, in particular in an automatic manner
  • the sleeve can, for example, be freely movable 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.
  • the sleeve in particular a circumferential diameter increase on the sleeve provided to form a mushroom head, and/or the receptacle of the closing part be shaped so that when the sleeve hits the entrance of the receptacle of the locking part, it is automatically moved into the correct position.
  • slopes, ramps or other guides that act as insertion aids can be provided on the sleeve or the closing part.
  • locking pins are known which can be manually adjusted to a specific length. This means that these locking pins can be set to a suitable length when installing a sash in a frame.
  • the frame since the frame "settles" over time due to its own weight, i.e. the end away from the band sinks a little over time, with such locking pins, due to the lack of automatic length adjustment, the length of the locking pin needs to be adjusted in order to ensure that the locking pin engages unhindered to ensure the locking part permanently.
  • Locking pins according to the preamble of claim 1 are out DE 10 2007 055568 A1 , DE 20 2008 003555 U1 , EP 1 683 938 A2 , DE 29 03 837 A1 and DE 32 43 858 A1 known.
  • GB 2 280 708 A a locking pin is also described, which as a whole can be axially offset relative to a drive rod via a thread.
  • a locking pin with the features of claim 1 and in particular in that 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, through which a maximum or minimum length of the Head part is defined, wherein different maximum positions or minimum positions can be set, in particular by adjusting the spacer element.
  • the sleeve of this locking pin is basically freely, in particular continuously, axially movably mounted on the inner pin of the head part at least between two limit positions (minimum or maximum length of the locking pin), but can be in a defined axial position, i.e. a specific position between the two Limit positions possible positions by means of which holding means are held.
  • the holding means can be a single element (despite the use of this term in the plural) or a device made up of several elements.
  • the holding means can 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 has a substantially permanent holding effect on the sleeve.
  • the defined axial position mentioned can be a position that is individually specified by a user, for example the user makes an adjustment to the holding means.
  • 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 rebate clearance.
  • the defined axial position can also change over time.
  • the defined axial position can also be a predetermined and/or unchangeable basic or neutral position of the sleeve, in which the sleeve is arranged, for example, essentially centrally between the two limit positions mentioned.
  • such a locking pin can be automatically moved to a suitable length of the head part due to its axial mobility, in particular through interaction with the locking part.
  • the holding means can, for example, only be activated by the engagement of the locking pin in the locking part or only when leaving the locking part to hold the sleeve.
  • the holding means are preferably permanently effective, so that it is preferred if the holding means are designed to hold the sleeve in the defined axial position in such a way that an, in particular automatic, adjustment of the axial length of the head part at least in one direction, preferably Both directions remain possible.
  • the holding means are not intended to prevent or hinder the automatic adaptability of the length of the locking pin to the respective rebate clearance. Rather, this automatic adaptability should be maintained and only wear should be minimized.
  • the sleeve can be held by means of the holding means in that axial position which corresponds to the length of the locking pin which is suitable for precise insertion into the locking part.
  • the holding means hold the sleeve in an adjustable, for example central position, from which only a slight automatic length adjustment is possible is required.
  • 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 into the position which is to be the new defined axial position in which the sleeve is to be held from now on.
  • the adjustment can also be made by adjusting a characteristic of the holding means, such as a spring constant, a contact pressure or a spatial orientation.
  • the holding means are designed to hold the sleeve in the defined position due to static friction.
  • the static friction is preferably designed in such a way that the sleeve can be axially offset by hand relative to the inner pin, but at least that the sleeve can be axially offset in cooperation with a respective closing part for the aforementioned automatic length adjustment, whereas displacement is prevented solely due to gravity becomes.
  • the result of the static friction is that the sleeve is simply held in the axial position into which it was last moved, but that the sleeve continues to be freely and in particular continuously axially adjustable between the limit positions mentioned by overcoming the static friction forces.
  • the holding means comprise those formed on the sleeve Clamping tabs adapted to apply radial pressure to the inner pin.
  • the sleeve can have an inner diameter that essentially corresponds to the outer diameter of the inner pin and with which the sleeve rests on the outer diameter of the inner pin.
  • the clamping tabs on the sleeve can be designed in such a way that, if the sleeve is detached from the inner pin, they would assume a substantially force-free rest position in which they protrude into the area of the inner diameter of the sleeve. However, if the sleeve is placed on the inner pin, the clamping tabs press radially on the inner pin and thus increase the static friction between the sleeve and the inner pin.
  • the sleeve has a cylindrical jacket shape at least in sections, the clamping tabs being formed by recesses in the manner of incisions in the cylindrical jacket shape.
  • the clamping tabs can therefore be produced in a simple manner by slotting the cylindrical jacket-shaped sleeve from an axial end, in particular regularly in the circumferential direction. The areas between these incisions then form the clamping tabs.
  • the sleeve can have radially inward projections or other types of diameter reductions (continuous or interrupted) in the area of the clamping tabs, for example at the axial ends of the clamping tabs.
  • the holding means comprise at least one biasing device for biasing the sleeve into a neutral position.
  • a pretensioning device is preferably a plate spring or another spring that requires a comparatively small installation space.
  • the sleeve is in this case Embodiment is therefore held in a defined axial position by being biased into the neutral position.
  • the neutral position therefore corresponds to the defined axial position and is determined by the action of the at least one pretensioning device.
  • the sleeve of the locking pin assumes the neutral position at least when no other significant forces act on the sleeve, in particular when the head part of the locking pin does not currently engage in an assigned locking part.
  • the pretensioning device is firmly connected to the inner pin on the one hand and to the sleeve on the other, a single pretensioning device can be sufficient to pretension the sleeve from both axial directions into the neutral position, which then simply corresponds to the rest position of the pretensioning device.
  • a preloading device is provided that is not connected to both the sleeve and the inner pin or another part of the locking pin, it may be that the sleeve is only preloaded from one axial direction into the neutral position and in the other axial direction from the Neutral position is freely movable up to one of the limit positions.
  • the biasing device can then, for example, be arranged in such a way that it biases the sleeve precisely against gravity.
  • the holding means comprise two pretensioning devices which pretension the sleeve in opposite directions with regard to its axial mobility.
  • the neutral position corresponds to a rest position of the system consisting of both prestressing devices. Displacing the sleeve from the neutral position in one axial direction then acts against the preload of one pretensioning device and displacing it in the other axial direction counteracts the preloading of the other pretensioning device.
  • the sleeve is prestressed by a respective prestressing device only in the respective edge regions of its axial mobility, but in between there is formed a prestress-free axial region, so to speak, in which the sleeve does not Subject to the force of the pretensioning devices and is therefore essentially freely movable axially.
  • the neutral position mentioned covers this entire area. This applies both if only one and if several prestressing devices are provided.
  • At least one pretensioning device is adjustable in terms of its pretension in order to be able to change the respective neutral position by changing the pretension.
  • a single constant neutral position is sufficient to achieve the advantages essential to the invention.
  • a respective pretensioning device is between a stop surface formed on a circumferential collar of the inner pin and one formed on an inner circumferential reduction of the sleeve Counter stop surface effective.
  • a (further) respective 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 counter-stop surface formed on an end face of the sleeve.
  • the stop surface of the circumferential collar of the inner pin and the counter-stop surface of the inner circumference reduction of the sleeve form, in particular, mutual undercuts that lock the sleeve against detachment from the inner pin.
  • a base plate can also be provided, for example in the form of a flat circumferential extension with, for example, a round cross section or a cross section suitable for applying an open-end wrench.
  • This base plate allows the axial mobility of the sleeve to be limited in the opposite direction up to a second limit position, which corresponds to a minimum length of the locking pin. It is therefore advantageous to provide respective pretensioning devices precisely between these stop surfaces and counter-stop surfaces, which may already be provided to limit the axial mobility of the sleeve.
  • 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, through which a maximum or minimum length of the head part is defined, with different maximum positions or .Minimum positions can be set.
  • the maximum position or minimum position set in each case corresponds to the defined axial position in which the sleeve is held by the spacer element.
  • the defined axial position is advantageously adjustable and is defined in particular by the fact that the axial mobility of the sleeve is limited by it at least in one direction.
  • the spacer element forms a support surface as a stop for the sleeve at a certain distance from one of the two limit positions of the axial mobility of the sleeve.
  • the mobility of the sleeve can be limited by the spacer element in the direction of movement in which the sleeve is pushed due to gravity.
  • the spacer element can therefore serve to shorten the distance that the sleeve travels between a locking position predetermined by the closing part when the sash is locked and a limit position assumed outside the closing part due to gravity, in order to reduce wear.
  • the spacer element has a support surface which is inclined to the plane and which cooperates with the sleeve in order to limit the mobility of the sleeve.
  • the sleeve can interact with the support surface at a different point, in particular rest on the support surface or hit the support surface. Since the course of the support surface is inclined relative to the plane of movement, different support points or support areas of the support surface are at different axial "heights" in relation to the headboard axis.
  • support points or support areas of the support surface of different axial heights can be selected in order to limit the mobility of the sleeve. Consequently, this axial limitation can be adjusted by moving the spacer element, so that different maximum positions or minimum positions of the sleeve can be set.
  • the course of the support surface can have a continuous and in particular constant axial increase or decrease in height. In principle, the course can also be discontinuous, approximately stepped, or have axial increases or decreases in height of variable steepness.
  • the spacer element is essentially designed as a wedge disk and is preferably movable within a plane perpendicular to the head part axis.
  • the spacer element therefore has a thickness that increases variably or preferably constantly, for example along a wedge axis.
  • an adjustable stop for variable limitation of the mobility of the sleeve can be implemented in a particularly simple manner.
  • the wedge disk can fill different and in particular differently long areas 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.
  • Possible movements of the wedge disk include, for example, translational movements, in particular in the direction of the wedge axis mentioned, or rotational movements within the plane mentioned.
  • the spacer element can be movably mounted, for example, on a bearing section of the locking pin.
  • the spacer element is movable within a plane perpendicular to the head part axis, for example by being translationally displaceable within the plane, for example along an axis, or rotatable about an axis.
  • the spacer element is rotatably mounted about an adjustment axis that is eccentric to the head part axis.
  • the adjustment axis is therefore arranged parallel to the headboard axis, but offset from the headboard axis.
  • the adjustment axis can in particular coincide with the mentioned foot part axis of the foot part of the locking pin.
  • the wedge disk is preferably at least substantially disk shape arranged perpendicular to the headboard axis. The result of this is that when the wedge disk rotates about the adjustment axis, the wedge disk remains aligned perpendicular to the head part axis and the adjustment axis, but the thickness of the part of the wedge disk that projects into the area of the head part axis that is eccentric to the rotation changes. This change in thickness due to the rotation of the wedge disk about the adjustment axis can advantageously be used to easily limit the mobility of the sleeve to a respective defined axial position (maximum position or minimum position) as desired.
  • securing means can also be provided which are manually operated or automatically block the spacer element against displacement.
  • the blocking can also simply consist of stabilizing the spacer element in a respective position by opposing a certain mechanical resistance to a displacement of the spacer element, which can, however, be overcome (without damaging the respective securing means).
  • a locking mechanism is effective between the spacer element and the bearing section in order to limit the arrangement of the spacer element relative to the bearing section to a limited number of defined positions.
  • the mobility of the spacer element is not infinitely variable, but rather fixed to transitions between a few defined positions through the interaction of the bearing section with the spacer element.
  • the displacement of the spacer element is therefore carried out in stages due to the locking mechanism mentioned. This allows the adjustment of the spacer element and thus the defined axial position of the sleeve to be restricted to certain conditions can be maintained particularly reliably due to the locking mechanism.
  • the spacer element with the inner circumference of a through opening rests on an outer circumference of the bearing section, with respective profiles of the through opening and the bearing section being designed relative to one another in such a way that stable positions of the spacer element are thereby defined and the spacer element consists of other, unstable positions is pushed into one of the stable positions.
  • the spacer element is therefore not completely freely displaceable due to the interaction of the profiles mentioned. Rather, this defines stable positions of the spacer element, into which the spacer element is advantageously pushed if it is not initially in such a stable position.
  • the stable positions thus determine which positions the spacer element can assume in the long term for adjusting the defined axial position of the sleeve.
  • the remaining positions are unstable positions in that the spacer element is exposed to forces in these positions that push it to a stable position, in particular the closest one, and preferably automatically move it into this stable position.
  • such a mechanism can be achieved with a spacer element rotatable about an adjustment axis in that the through opening has a hexagon socket or another internal polygon as a profile and the bearing section is at least essentially designed as an external hexagon or an external polygon corresponding to the internal polygon, but at least one of the Profiles differ from this basic shape to a certain extent, in particular having rounded corners and / or 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 evenly distributed to one another (more stable) positions, although the positive connection between these profiles is not exact.
  • the deviations mentioned between the profiles are in particular such that, at least with sufficient elastic deformability of the through opening and/or the bearing section, rotation of the spacer element relative to the bearing section against the actual positive fit is possible.
  • the profile of the bearing section and the profile of the through opening are pressed against each other as long as a stable position is not reached again. As a result of this force, the spacer element essentially inevitably locks back into one of the stable positions at the end of a rotational movement.
  • the holding means in addition to the spacer element, comprise a pretensioning device for pretensioning the sleeve into the respective maximum position or minimum position.
  • the sleeve is not only limited in its axial mobility to a defined axial position, namely a maximum position or minimum position, by the spacer element, but is also prestressed into this position.
  • the sleeve is therefore still axially movable between the maximum position or minimum position and the opposite limit position, so that the aforementioned automatic length adjustment of the locking pin is still possible.
  • the sleeve does not interact with an associated locking part, it assumes the maximum position or minimum position due to the preload.
  • Such a locking pin can be used particularly flexibly at different points on a sash or frame, can be adjusted in a defined axial position to reduce wear and yet has automatic length adjustment.

  • the inner pin 17 also has a circumferential collar 25 on its outer circumference, which widens the diameter of the inner pin 17 represents.
  • This inner circumference reduction 27 and the collar 25 engage behind each other, so that the sleeve 19 is permanently mounted on the inner pin 17.
  • the axial mobility of the sleeve is limited by the interaction of the collar 25 and the inner circumference reduction 27 in the direction away from the foot part 13 to a limit position which corresponds to a maximum length of the head part 15 or the locking pin 11.
  • the axial mobility of the sleeve is limited in that it abuts the base plate 21 or another stop formed at the transition between the foot part 13 and the head part 15 with an end face 29 facing the foot part 13.

  • the area of greatest thickness is therefore located in the same direction as the head part axis K with respect to the adjustment axis E, while the area of smallest thickness of the spacer element 41 is aligned diametrically opposite to this.
  • the through opening 43 of the spacer element 41 has the profile of a hexagon socket.
  • the profile of the bearing section 45 is accordingly designed as an external hexagon, whose corners are, however, rounded.
  • the spacer element 41 is therefore actually locked in a form-fitting manner against rotation about the adjustment axis E.
  • the through opening 43 of the spacer element 41 has sufficient elasticity to still enable rotation.
  • the rounded corners of the profile of the bearing section 45 are then at least temporarily pressed against respective edges of the profile of the through opening 43, whereby the edges are slightly deformed and exert counter pressure on the respective corners.
  • the pressure only decreases when a stable position is reached again, i.e. a position in which corner to corner and edge to edge are again, of which there are six due to the hexagonal profile. In other positions, which are therefore unstable, the pressure mentioned causes the spacer element 41 to, so to speak, snap into the nearest stable position.
  • the sleeve 19 is by one of the pretensioning devices 39 in Figures 2A and 2B shown unclaimed embodiment comparable biasing device 39 biased in the direction of the respective minimum position.
  • the sleeve 19 is held in a respective defined axial position by holding means 35, 37, 39, 41, in the three illustrated embodiments of a respective locking pin 11 it is achieved that the locking pin 11 is easy to operate automatically is adjustable in length and has reduced wear.
