Description

Detailed Description of the Invention

[0001] The present invention relates to a child containment device, in particular a child seat for mounting on a car seat, a stroller or a child containment device for such a seat and / or a highchair.

[0002] For example, a child seat for mounting on a car seat is known from the prior art, in which the headrest is height adjustable relative to the body of the child seat. A conventional design of a locking mechanism is described, for example, in DE 10 2013 107 533 A1. The mechanism described in this document, for example, has been known for a long time and comprises a drive part with two guide slots in the lower part, the two guide slots being inclined symmetrically to the displacement axis of the drive part, and two latches having parts that are each movable in the guide slots so that the headrest is either locked or unlocked.

[0003] This prior art solution is still perceived as being relatively error prone and is considered to be disadvantageous in terms of ease of use and safety.

[0004] The object of the invention is to propose a child restraint device, the two parts of which, being movable relative to one another, can be adjusted in a relatively simple and reliable or safe manner.

[0005] This object is achieved in particular by the features of claim 1.

[0006] In particular, this object is achieved by a child accommodation device, in particular a child seat for attachment to a car seat, a baby stroller or a child accommodation device for such a baby stroller and / or a highchair, which comprises a first part and a second part which is movable relative to the first part in order to adjust the child accommodation device (preferably in such a way that the first part and / or the second part do not change their respective shapes), the second part being lockable relative to the first part by means of a locking device (belonging to the child accommodation device), and an adjusting device (control device or drive device) which is movable from a first adjusting device position to a second adjusting device position in order to move the locking device from the first locking device position to the second locking device position, one of the first and second locking device positions being an unlocked position in which the first part and the second part are not locked relative to each other and the other of the first and second locking device positions being an unlocked position in which the first part and the second part are not locked relative to each other and the other of the first and second locking device positions being an unlocked position in which the first part and the second part are not locked relative to each other. and an adjusting device in a locked position in which the first and second parts are locked relative to each other, the adjusting device having at least one first control part and the locking device (blocking device) having at least one second control part, the first and second control parts interact with each other to move the locking device from the first locking device position to the second locking device position when the adjusting device moves from the first adjusting device position to the second adjusting device position, the adjusting device having at least one third control part and the locking device having at least one fourth control part, the third control part and the fourth control part interact with each other to move the locking device from the second locking device position to the first locking device position when the adjusting device moves from the second adjusting device position to the first adjusting device position.

[0007] Preferably, the at least one control is designed as a track control and the at least one further control moves or runs (preferably sliding and / or rolling) along the track control when the locking device moves from the first locking device position to the second locking device position. Preferably, the at least one control designed as a track control is part of the adjustment device and the at least one further control designed as a track control is part of the locking device. Alternatively or additionally, the at least one track control is not defined by a recess or at least not defined by a slot-shaped recess or at least not defined by a slot-shaped recess that defines the further control designed as a track control (and is located between the track control and the further track control).

[0008] One idea of ​​the invention is to form at least one track control for controlling the adjustment of the locking device (from a first locking device position to a second locking device position or vice versa) in such a way that a corresponding control (e.g. a lug, rod and / or pin) moving along the track control can and / or may move at least partially away from itself (where "could" means in particular that the path movement is (only) indirectly limited or prevented, e.g. by the overall mechanism, but is in any case not prevented by the track control). As a result, undesired malfunctions (e.g. practically minor damage and / or jamming of sliding elements, e.g. due to practically minor deviations in the manufacturing process) can be avoided or the corresponding risks can at least be reduced. Overall, reliability and comfort in operation as well as safety are improved.

[0009] A control of a locking device or an adjusting device is to be understood in particular as a part of the respective device which produces, partially (e.g. together with another corresponding control) or completely, an active connection (in particular a force-transmitting active connection) between the locking device and the assigned adjusting device. A control should in particular be defined by being in contact (while transmitting a force or while pressing) with an assigned (complementary) control during the active transmission.

[0010] A track control is to be understood as a control along which a complementary control (designed as a track control or otherwise) moves (or runs), in particular slides or rolls, during adjustment of the locking device. The control may or may not have a certain extension perpendicular to the direction of movement of the complementary control. In the case of a track control, in particular not all points of the track control are in contact with the complementary control at a given time. In this respect, a track control is to be understood as the total number of points which are in contact with the complementary control at least temporarily (possibly only at a certain time) during adjustment of the locking device. The complementary control for the respective track control may be a rail section or may be designed as a running control. In the case of inclined slots, there will in particular be two track controls (per slot) in the form of two mutually facing longitudinal edges of the slot, as shown, for example, in DE 10 2013 107 533 A1. The track control generally should not be (but may be) limited to embodiments in which the control has a guide structure (e.g., folds, grooves, slots, or webs) or is part of such a structure.

[0011] A travel control is to be understood as a control in which, during adjustment of the blocking, the same point always (or repeatedly in the case of rolling) comes into contact with a corresponding complementary control (in particular a track control), which may preferably be a curve or a rail and the travel control may be a protrusion (for example a pin) and / or a rod running along this rail.

[0012] The (respective) adjustment device (respective adjustment element) may be formed integrally, possibly seamlessly, or may be constructed from multiple, possibly seamless, pieces.

[0013] The adjustment or relative movement of the first part with respect to the second part, in particular the height adjustment, may be performed via an adjustment device for adjusting the (respective) locking device and / or by an additional adjustment device for such adjustment.

[0014] The (respective) locking device (respective locking element) may be constructed integrally, possibly seamlessly, or may optionally be constructed from multiple (e.g., two in each case), possibly seamless, pieces (components).

[0015] The first part and / or the second part may constitute a substantial portion of the child containment apparatus, e.g., in terms of weight, at least (respectively) 2%, 5% or 15% and / or may extend over at least 5%, preferably at least 15% or at least 25% of the total height of the child containment apparatus in at least one state of use and / or may extend over at least 5%, preferably at least 15% or at least 25% of the total depth of the child containment apparatus in at least one state of use of the child containment apparatus.

[0016] In particular, the release position is to be understood as the position of the locking device in which the adjustment device (in principle) allows a relative movement of the first part with respect to the second part. If necessary, further devices (e.g. further locking devices) may be present, which must also be released to allow the overall relative movement. If necessary, (exactly) one, or (exactly) two or more than two locking devices may be present, in which case release (to allow the relative movement) is preferably possible (only) when all of the locking devices are in their respective release positions. The movement of each of the possibly multiple locking devices to their release positions may be forced to be interlocked, if necessary (in particular so that the locking devices can be moved together (possibly exclusively) to their respective release and / or lock positions).

[0017] Typically, the (respective) adjusting device is preferably actively connected to an (assigned) locking device (latch device or latch), such that a movement of the adjusting device (of the adjusting element) in a first direction drives the locking device (locking element) in a second direction (in particular a direction different from the first direction). Preferably, the first and second directions are at least substantially perpendicular to each other (or extend at an angle in the range of 30°-150°, preferably 60°-120°, more preferably 85°-95°). Alternatively or additionally, the second direction is oriented towards or away from the adjusting element.

[0018] An active connection may be realized by a connection in which the two devices (elements) are in direct contact or indirectly via at least one intermediate element (e.g. a transmission element such as a pulling element and / or a pushing element). The (active) connection is preferably mechanical, in particular non-electrical and / or non-electronic. For example, the active connection may comprise a frictional connection.

[0019] At least one control designed as an orbital control and at least one further control designed as an orbital control may at least partially point (at least substantially) in the same direction. In particular, this should be understood to mean that it applies that for a portion of each control, the corresponding surface normal of this portion has an angle of less than or equal to 30°, more preferably less than or equal to 15°, even more preferably less than or equal to 5°, possibly even 0° with respect to the corresponding surface normal of the respective other control. Preferably, the above condition applies to at least 50%, more preferably at least 90% of the contact surface of the corresponding control (with corresponding suitable angle limitations).

[0020] Alternatively or additionally, at least one control designed as an orbital control and at least one further control designed as an orbital control are designed at least partially to point at least substantially away from each other. By "substantially" it is to be particularly understood that for a portion of each control, the corresponding surface normal of this portion has an angle of 150° or more, more preferably 170° or more, even more preferably 175° or more, even 180°, with respect to the corresponding surface normal of the respective other control. Preferably, the above condition applies to at least 50%, more preferably at least 90% of the contact surface of the corresponding control (with corresponding suitable angle limitations).

[0021] Further alternatively or additionally, at least one control designed as a track control and at least one further control designed as a track control are designed to at least partially, at least substantially, face each other. By "substantially" it is to be particularly understood that for a portion of each control, the corresponding surface normal of this portion has an angle of 150° or more, more preferably 170° or more, even more preferably 175° or more, even 180°, with respect to the corresponding surface normal of the respective other control. Preferably, the above condition applies to at least 50%, more preferably at least 90% of the contact surface of the corresponding control (with corresponding suitable angle limitations).

[0022] Particularly preferred are (track) controls which, at least in part, at least substantially point in the same direction or away from each other, so that the risk of malfunction of the locking mechanism (e.g. possible jamming when the track controls point towards each other, in particular when they are formed by a common slot) can be reduced in a particularly simple manner.

[0023] However, it may also be advantageous for the trajectory control parts to point towards each other, for example when there is a relatively large distance between them (e.g. a distance of at least 1 cm or at least 2 cm) and / or when they are defined by different devices (elements).

[0024] At least one (or several or all) of the track control parts may be straight (linear). Alternatively or additionally, at least one (or several or all) of the track control parts may extend non-straight, preferably at least partially curved, in particular arc-shaped. Alternatively or additionally, at least one (possibly several or all) of the track control parts may extend obliquely to the direction of movement of the adjustment device and / or obliquely to the direction of movement of the locking device. An oblique path is to be understood in particular as a path in which the track control parts (at least partially, in particular in the case of a non-straight or curved path) have an angle of at least 15°, preferably at least 30° and / or at most 80°, preferably at most 60°, for example at least about 45°, to the respective direction of movement.

[0025] Preferably, at least one control (preferably cooperating with a track control) is designed as a travel control, preferably in the form of a protrusion, in particular a pin or an arc-shaped protrusion, for example a hemispherical protrusion, and / or in the form of a rod. In an embodiment, each track control may be assigned (possibly exactly one) travel control, which comes into contact with the track control when the locking mechanism is adjusted.

[0026] Preferably, the first part and the second part are movable relative to each other, the purpose of which is to Adjusting the height of the head restraint and / or shoulder belt guides, and / or Adjusting the inclination of the seat (seat element) (e.g. relative to the seat base or frame) and / or Adjusting the inclination of parts of the seat (seat elements), in particular the backrest and / or the seat part (e.g. towards each other or towards the seat base or frame), and / or Adjusting the rotation of the seat (seat element) relative to the seat base and / or the rotation of the rotating plate of the seat base relative to the fixed part of the seat base and / or Adjusting the extension length of the locking system, in particular the Isofix system, and / or Adjusting the locking of the frame, in particular of the stroller, in the use position and / or in the storage position, and / or Adjusting the extension length and / or inclination lock of the push bar or push bar parts, in particular of the stroller, and / or Adjusting the locking of the height position (high / low) and / or depth position (front / back) of the seat element, in particular of a highchair, and / or of the back element, in particular of a highchair, or of the footrest, in particular of a highchair, respectively, relative to the frame It is.

[0027] Particularly preferably, the child accommodation device is a child seat. More preferably, the first part and the second part are a body and a headrest of the child seat (or vice versa).

[0028] The adjustment device preferably comprises an actuation device or is (actively) connected to such an actuation device. If necessary, the actuation device may be partly part of the adjustment device or may have further elements (actively) connected to the adjustment device. The actuation device may preferably be manually operable (directly, i.e. in particular by directly using the operator's fingers and / or hands and / or feet) and more preferably may comprise a handle and / or a manually operated lever (which in turn may for example have a recess and / or at least one hole and / or at least one groove).

[0029] The actuator (actuating element) may be formed integrally, possibly seamlessly, or may be formed from multiple pieces.

[0030] The actuation device (actuation element) is (actively) connected to the adjustment device (adjustment element) so that actuation of the actuation device can drive the adjustment device (in particular in a first direction). This connection (active connection) may be realised by designing the actuation device and the adjustment device (adjustment element) together as one element (possibly seamlessly), or by a fixed (possibly rigid) connection of both elements, or possibly by another (possibly direct) connection of the two elements, or indirectly via at least one intermediate element (e.g. a transmission element such as a pulling device / pulling element and / or a pushing device / pushing element). This connection is preferably mechanical, in particular non-electrical and / or non-electronic. This active connection may comprise a force-fit and / or a frictional connection.

[0031] The adjustment device may be movable in a first direction and the locking device may be movable in a second direction. Preferably, the first and second directions are different from each other. More preferably, the first and second directions are at least substantially perpendicular to each other (or have an angle of at least 60° and / or at most 120° relative to each other). Alternatively or additionally, the second direction may be oriented towards and / or away from the adjustment device.

[0032] The (respective) adjusting device and / or the (respective) locking device and / or the (respective) actuating device may be pretensioned and / or pretensionable in at least one position by at least one spring device, preferably such that the locking device (locking element) is biased in a direction towards a blocking position (locked position, blocked position) or away from a release position.

[0033] At least one trajectory control portion may comprise a control edge and / or a control surface and / or may be designed as a (straight or non-straight, e.g. curved) control curve in at least one projection (e.g. a projection in a plane defined by the movement direction of the respective assigned adjusting device and the respective locking device).

[0034] At least one (exactly one, possibly several or all) adjusting device (adjusting element) may be assigned to (in each case) at least one or exactly one locking device.

[0035] At least one (exactly one, possibly several or all) adjusting device (adjusting element) may be assigned to (in each case) at least two or exactly two locking devices.

[0036] The adjusting device may be guided in an adjusting device guide device, which may preferably be guided in a corresponding guide device (i.e. a guide device of the adjusting device guide device). Alternatively or additionally, the locking device may be guided in a locking device guide device, which may preferably be guided in a corresponding guide device (i.e. a guide device of the locking device guide device), in particular in an assembly slide. If necessary, a common (possibly self-guiding) guide device (slide) may be provided for guiding the adjusting device and the locking device. The (respective) guide device may comprise rails and / or notches, for example formed by rods and / or bars and / or tubes and / or splines and / or square shafts.

[0037] The adjuster may be movable from a first adjuster position to a second adjuster position by rotation and / or (preferably) by translation.

[0038] The locking device may be movable from the first locking device position to the second locking device position by rotation and / or (preferably) by translation.

[0039] The at least one control part designed as a track control and the at least one further control part designed as a track control can be oriented away from each other and / or can be formed on the locking device. Alternatively or additionally, the at least one control part designed as a track control and the at least one further control part designed as a track control can be oriented away from each other and / or can be formed on the adjustment device.

[0040] The above object is further achieved, in particular, by a method for adjusting a child restraint device as described above and / or below, wherein the adjustment device is actuated, in particular manually (indirectly or directly), to move from a first adjustment device position to a second adjustment device position, thereby moving the locking device from the first locking device position to the second locking device position.

[0041] Further method features may be derived from the above and / or below description of the child containment device, in particular functional features may be implemented as specific method steps (e.g. movement from a first position to a second position may be specifically performed or initiated).

[0042] The adjusting device (adjusting element) preferably comprises at least one first control and at least one third control. The locking device (locking element) preferably comprises at least one second control and at least one fourth control. Each control may be designed as a control edge and / or a control surface. When the locking device (locking element) is in its locked position and the adjusting device (adjusting element) is actuated, if applicable, via the actuating device (actuating element) so that the adjusting device is driven in a first direction to move from the first adjusting device position to the second adjusting device position, the first and second controls may interact such that the locking device (locking element) moves from its locked position to the released position (released position).

[0043] When the actuation device (actuation element), preferably by (at least) one spring, is actuated to move the adjustment device (preferably in a direction opposite to the first direction) from the second adjustment device position to the first adjustment device position, the third and fourth controls may interact such that the locking device (locking element) moves from the release position to the locked position (locked position). Preferably, the first and second controls are slidably connected. Alternatively or additionally, the third and fourth controls are slidably connected. A connection with at least one (or possibly multiple) rolls may also be realized.

[0044] The (respective) control part may be defined by being involved in the (active) connection, in particular in the transmission of forces between the adjusting device (adjusting element) and the locking device (locking element). Two parts are not (respectively) a control part if they are merely in contact. The first and third control parts are preferably spatially separated from each other so that they are not (directly) adjacent to each other. Alternatively or additionally, the second and fourth control parts are preferably spatially separated from each other so that they are not (directly) adjacent to each other. One of the first and third control parts may be smaller than the other of the first and third control parts. Alternatively or additionally, one of the second and fourth control parts may be smaller than the other of the second and fourth control parts. The size is preferably for the (contact surface) of the respective control part.

[0045] When the projections of the adjusting device (adjusting element) and the locking device (locking element) are viewed in a plane defined by the first and second directions, preferably at least one (possibly only one) of the first and second controls looks like a control curve, preferably like a control segment, and at least one (possibly only one) of the third and fourth controls looks like a control curve, preferably like a control segment. An end point of the control curve (trajectory control) assigned to the larger (or longer) of the first and second controls may define a release segment. Alternatively or additionally, an end point of the control curve (trajectory control) assigned to the larger of the third and fourth controls may define a block segment.

[0046] The release segment and the block segment may extend at least substantially parallel, preferably exactly parallel, to each other, and / or may be at least substantially the same length, preferably exactly the same length. In this context, "substantially parallel" may preferably mean that both segments form an angle of less than 10° (e.g., at most 3°). "Substantially the same length" may mean that each of the release segment and the block segment is longer than a similarly constructed segment for the two smaller controls. Exactly the same length and exactly parallel may possibly include standard manufacturing tolerances.

[0047] In an embodiment, two locking devices (two locking elements, e.g. latches) may be assigned to the adjustment device (adjustment element), which may then comprise two first controls and two third controls. One first control and one third control may cooperate with a first locking element (of the first locking device), and the other first control and the other third control may cooperate with a second locking element (of the second locking device). The adjustment device (adjustment element) is preferably formed symmetrically in this case, in particular symmetrically with respect to a plane.

[0048] Further embodiments result from the dependent claims. The invention will now be described with reference to exemplary embodiments, which will be explained in more detail with reference to the drawings, in which: FIG. [Brief description of the drawings]

[Figure 7] 5b shows a further alternative embodiment of the portion shown in FIG. 5a. [Figure 8] 5b shows a further alternative embodiment of the portion shown in FIG. 5a. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0050] In the following description, the same reference numbers are used for parts that are identical and operate identically. Fig. 1 shows a child seat (specifically a baby seat) with a locking mechanism according to the invention for adjusting the position of the headrest (or the height of the headrest). The locking mechanism itself cannot be seen in detail. The child seat has a body 10 (first part) and a headrest 11 (second part).

[0051] Figure 2 shows a headrest 11 of the child seat according to figure 1, comprising a support 12 for the child's head, which may normally be covered by a pad (not shown) and / or a cover. The headrest 11 comprises an actuating device 13, which has an actuating handle at its upper end. The actuating device (actuating element) 13 may be formed integrally with an optional pulling element (pulling part) 14 (as in this figure). Alternatively, a design with separate elements is also possible.

[0052] The tension element (tensioning device) 14 is connectable (preferably at its lower end, as shown in Fig. 2) to an adjustment device (adjustment element) 15, which, upon actuation, is driven to move upwards as well, in particular by being pulled upwards (or along the support 12) away from the adjustment device or the at least one locking device (hereafter always referred to as "upwards"). Furthermore, at least one locking device 16 (here in particular exactly two locking devices 16) is provided, each locking device 16 optionally having a latch element 17 and possibly a protrusion 18.

[0053] Figure 3 shows the parts of the headrest 11 from Figure 2 with the locking mechanism in the locked position. An adjusting slide 19 is provided (which can be connected, for example rigidly, to the support 12, for example by means of a screwed and / or glued and / or snap-hook connection). A spring device 20 is assigned to the adjusting device 15. Furthermore, the adjusting device (adjusting element) 15 is guided in the adjusting slide 19 so that it can be pulled upwards.

[0054] Alternatively or additionally, other spring devices (spring mounting parts) can also be used, for example the actuating device (actuating element) or the tensioning device (tensioning element or tensioning part) can be spring mounted and / or the respective locking devices can be spring mounted (e.g. relative to the adjustment slide and / or relative to each other).

[0055] Instead of a coil spring (compression spring) (as shown), it is also possible to provide one or more other springs.

[0056] The adjustment device (adjustment element) can, in particular at its lower end, embrace a projection 18 of the (respective) locking device by means of two lateral arms 21 respectively.

[0057] A double (encircling) design of the arms can provide additional security, but this is merely an option for realizing the locking mechanism according to the invention, since one arm (per side) would also be sufficient, or even other configurations are possible.

[0058] Even more generally, for example, only one locking device is necessary to realize this locking mechanism. However, for additional security, it may be advantageous to provide two locking devices (especially mirror images, as shown in the figures). However, the above and below statements regarding the locking devices themselves are also advantageous when only one locking device is provided.

[0059] The (respective) arm 21 may have a recess (hole) 22 suitable for receiving a (respective) pin (shown in dashed lines in FIG. 4) of the (tensioning part) of the tensioning device 14. Furthermore, the (respective) protrusion 18 may have a second ramp 23, and the (respective) protrusion 18 in the illustrated embodiment (which is not essential) further has a web 24 for stabilization and better guidance, which together with the second ramp forms an (at least approximately) triangular recess 28, through which the pin 27 also passes. The illustrated configuration can be modified in a simple manner, for example the adjustment device (adjustment element) can be formed with only one arm on each side and with several pins, for example pointing forward, and the tensioning device (tensile element) or tensioning part can in this case have a receiving hole for the pin 27.

[0060] The pin 27 can interact with the (second) ramp 23 such that an upward movement of the pin drives the (respective) locking device to move inwardly from the locked position to the unlocked position. The adjustment device 15 can also have at least one (first) ramp 25, in particular (optionally) right and left first ramps 25. These can be designed to cooperate with the internal head 26 of the respective locking device to drive the latch from its unlocked position back to the locked position after the operation under the tension of the spring device 20 has ended.

[0061] Here, the second ramp 23 can define the second control mentioned above (and therefore also the release segment described above), the head 26 can define the fourth control, the pin can define the first control, and the first ramp 25 can define the fourth control (and therefore also in particular the block segment mentioned above).

[0062] Figure 4 shows the arrangement of Figure 3, but now in the unlocked position, with the (respective) locking device (locking element) moving inwardly such that it no longer engages with the corresponding locking structure (e.g., recess and / or hole) (not shown).

[0063] 5a-5b show a (complete) operating cycle of the parts of the locking structure according to the invention. In particular, an adjustment device 15 (adjustment element) with a receiving hole for a pin 27 (first control) with a first ramp 25 (fourth control) and a locking device (locking element) with a second ramp 23 (second control) and a head or a corresponding protrusion 26 (fourth control) are shown. The pin 27 may be an (integral) part of the adjustment device, whereby a potential tensioning device can also be attached to the adjustment device in a different way. Furthermore, a unit with an adjustment device and a tensioning device can also be understood as a (multi-part) adjustment device.

[0064] FIG. 5a shows the start of actuation of the (not shown) actuation element (actuation device, which can be part of the adjustment device and / or tension device), i.e. still in the locked position. The pin 27 abuts (directly) on the respective second ramp 23, while the head 26 and the first ramp 25 are slightly spaced apart. Such a (relatively small) distance is preferred but not essential. The respective end points of the release and block segments are highlighted with dots. It can be seen that the release and block segments are of the same length and parallel to each other. However, deviations therefrom are relatively easily realised by design (and are included in the present disclosure). The engagement structure 29 (e.g. with a recess and / or a hole and / or a protrusion and / or a pair of protrusions) is also shown diagrammatically, and preferably at least two engagement positions should be realised, not just the one shown.

[0065] Figure 5b shows the element of Figure 5a but now in the release position or with the actuator (not shown) still operating. The (respective) pin 27 has moved from one end of the release segment to the other end relative to the second ramp 23. The latch 17 is no longer engaged with the engagement structure.

[0066] Figure 5c shows the element of figure 5b, but in a state after (immediately after) the end of the actuation: the adjusting device (adjusting element) overcomes the spacing under the spring force of a spring device (not shown), the head 26 is now in contact with the first ramp 25, while the pin 27 and the second ramp 23 are now slightly spaced apart.

[0067] Figure 5d shows the element of figure 5c, but now again in the locked position: the adjusting device (adjusting element) 15 has been moved all the way down (in the figure) under the force of a spring (not shown) and the locking device 16 has been driven or moved via the head 26 into the locked position.

[0068] Figure 6 shows an alternative to Figure 5a, where both ramps 25, 23 curve in the same direction. The respective end points of the release and block segments are highlighted with dots.

[0069] Figure 7 shows an alternative to Figure 5a, where both ramps 25, 23 are curved in opposite directions. The respective end points of the release and blocking segments are highlighted with dots.

[0070] 8 shows another alternative, where the adjusting device 15 (adjusting element) has a first ramp (first control) 25, which defines a release segment and interacts with a pin (second control) (shown as a circle) of the locking device 16 (locking element). Furthermore, the adjusting device (adjusting element) has a head (third control) 26 which cooperates with a second ramp (fourth control) 23 (of the locking element) of the locking device.

[0071] 9-11 show further alternatives, starting with FIG. 9 where the adjustment device 15, the locking device 16 and the engagement structure 29 are shown apart from each other. The locking device (latch device) 16 has a ridge 30 in the form of an inclined block (e.g. pointing outwards from the image plane). This block defines on its two long sides two ramps 25,23 which may function as second and fourth controls 25,23 (here track controls). The adjustment device 15 has two pins (e.g. protruding into the image plane) or receiving holes for such pins which may function as first and third controls 27,26.

[0072] Figure 10 shows the elements shown in Figure 9 in the locked position of the locking device 16. Here, the third control 26 and the fourth control 25 are shown in contact, which may exist, for example, by a spring device (not shown) driving the adjustment device (adjustment element) 15 downwards.

[0073] Figure 11 shows the elements shown in Figure 9 in the unlocked position of the locking device 16. Here, the first control 27 and the second control 23 are shown in contact, which may exist, for example, by the application of an external (possibly manual) force via an actuating device (not shown) against the force of a spring device (not shown) which drives the adjusting device (adjusting element) downwards.

[0074] Naturally, with the understanding of the illustrated embodiment, it is also possible to provide two track control sections on the adjusting device (on the adjusting element) and two travel control sections on the locking element.

[0075] It should be noted here that all the above-mentioned parts / components or functions, whether seen alone or in any combination, are claimed as essential to the invention, especially with respect to the details shown in the drawings, variations thereon being known to those skilled in the art.

[0076] It is further pointed out that the widest possible scope of protection is sought. In this respect, the disclosure contained in the claims can also be characterized by features that are described together with further features (even if these further features are not necessarily included). It is expressly pointed out that parentheses and the term "in particular" are intended to highlight the optionality of a feature in the respective context (this does not mean, on the contrary, that a feature should be considered as essential in the corresponding context in the absence of such a distinguishing marking).
