Such a conditioning device can be formed in a simple and compact manner. For example, such a conditioning device can be made of plastic parts. As a result, it can be implemented cost-effectively and realized with low weight.

The first contact element is placed on the laying on a bottom element, so that the first contact surface rests on an upper side of the bottom element and the second contact surface on a front side. By means of the relative displacement position between the second contact element and the first contact element, it is then possible to set and fix a wall distance. After fixing the bottom element, the contact device can be solved in a simple manner even with a tension by the distance between the first contact element and the second contact element (based on the second contact surface and the third contact surface) is released or the determination is canceled.

Such a conditioning device can also be formed with a small height. When laying floor elements, a plurality of such installation devices can also be used.

The first contact element has, on a side opposite the first contact surface, a recess delimited by an edge, in which the second contact element is arranged. In particular, the second contact element does not protrude beyond the edge in a height direction. This makes it possible to realize a compact installation device with minimized height dimensions. The second contact element can thereby be arranged and guided in the manner of a drawer on the first contact element in the recess.

Characterized in that the second contact element is located in the recess of the first contact element, the first contact element can be to the second contact surface train closed. This results in a high mechanical rigidity and stability of the first contact element and thus also the contact device. As a result, in turn, a mechanism for the mobility of the first contact element and the second contact element can be easily arranged on one side of the first contact element, which lies opposite the second contact surface.

The corresponding mechanism is then protected by the closed formed first contact element (or the second contact surface) from soiling and damage, etc. to the second contact surface out.

If, for example, a rotatable locking element is provided, by means of which a relative position of the second contact element to the first contact element in one direction from the third contact surface to the second contact surface is detectably adjustable, then at most one recess (in the second contact element) must be provided for this locking element be provided. At the first contact element no fundamentally limiting the rigidity recess must be provided.

In particular, the second contact surface and the third contact surface are at least approximately parallel to one another. As a result, an alignment of, for example, a floor element to a wall can be adjusted in a simple manner.

It is advantageous if the second contact surface protrudes beyond the first contact surface and, in particular, that the first contact surface and the second contact surface intersect in a line. As a result, the second contact surface can be applied transversely to one side, for example a base element, on which the first contact surface is created. As a result, the first contact element can then no longer be displaced relative to the corresponding bottom element, since the second contact surface rests.

The line is in particular at least approximately parallel to the third contact surface. This results in a simple adjustability.

It is advantageous if the first contact element has an L-shaped configuration in cross-section at least on the first contact surface and the second contact surface. It is thus provided a leg for the second bearing surface to prevent displacement of the first contact element, for example on a floor element.

The corresponding abutment device can be produced in a simple and compact manner and in particular produced solely from a plastic material, if a first region of the first abutment element, on which the first abutment surface is formed, and a second region of the first abutment element, on which the second abutment surface is formed , are integrally connected.

It is advantageous if the first contact element has a profiling on the second contact surface. It can thereby prevent slipping. Furthermore, for example, unevenness on an element to be laid, such as floor element, can be compensated. Under certain circumstances, the first contact element may also have a nose for providing an undercut surface.

It is advantageous if the second contact element is supported on the first contact element. By a corresponding support can be realized in a simple manner, a sliding displacement. As a result, the contact elements can in turn be formed in a simple manner and, in particular, completely made of plastic.

It is particularly advantageous if the second contact element is guided in a linearly displaceable manner via a guide device and on the first contact element. As a result, the investment device can be realized in a structurally simple manner. The guide device can be trained in a simple manner and in particular can also be formed integrally on the first contact element and / or second contact element.

It is advantageous if the guide device is designed as a lift-off for the second contact element relative to the first contact element. As a result, the individual parts of the system can be held together without, for example, screws or the like must be provided.

In one embodiment, the guide means on opposite guide recesses, which are each bounded by a ceiling strip and in which respective guide rails are immersed. As a result, a linear guide can be realized in a simple manner. Furthermore, a lift-off protection can be realized in a simple manner. It can thereby realize a Gleitverschieblichkeit the second contact element on the first contact element in a simple manner, in particular, first contact element and second contact element can be made entirely of plastic. The corresponding guide device can be formed integrally, in particular, if, for example, the contact elements are produced in an injection molding process.

It is favorable if at least one ceiling strip is bevelled on a side facing away from the first contact surface. As a result, the production of the investment device is facilitated. It is provided by a plug-in wedge, which facilitates the assembly.

It is provided a locking device by which a relative position of the second contact element to the first contact element at least in the direction of the third contact surface on the second contact surface is adjustable to detect. As a result, a defined distance can be determined, and thereby a defined distance, for example, of a floor element close to the wall can be set to a wall. The statement does not necessarily have to be in two directions, but rather it is sufficient that a statement regarding the addition of the second contact element to the first contact element takes place.

The locking device has at least one locking element, which is supported on the first contact element and / or on the second contact element. As a result, for example, no threads are necessary; the determination is achieved by support (Appendix).

In one embodiment, it is provided that a first locking element is supported on a further locking element.

It is advantageous if the at least one locking element has at least one handle bar for manual operation. As a result, the locking element for its operation (for example, displacement and rotation) can be easily handled by an operator and it can exercise a corresponding force effect.

It is particularly advantageous if the at least one locking element is arranged movably relative to the first contact element and movably relative to the second contact element. The mobility may be linear displacement or rotation and so on. By relative movement of the at least one locking element relative to the first contact element and the second contact element, a sliding displacement of the first contact element towards the second contact element can thereby be effected and determined.

In particular, the at least one locking element is movable in a direction which is oriented transversely to a direction of movement of the second contact element relative to the first contact element and in particular a guide means for the movable mounting of the at least one locking element is provided. It can be provided, for example, that the at least one locking element is linearly displaceable with a linear displacement direction, which transverse (and in particular perpendicular) to a Displacement direction of the second abutment element to the first abutment element (with respect to the Gleitverschieblichkeit). It is also possible that the at least one locking element is rotatably mounted with a rotational angle direction, which is transverse to the displacement direction of the second contact element to the first contact element.

In one embodiment, the at least one locking element is mounted linearly displaceably on the first contact element and / or the second contact element. As a result, a spacer can be realized in a simple manner, which defines a specific displacement position of the second contact element to the first contact element.

In one embodiment, the at least one locking element is designed as a wedge element. This makes it easy to set different distances.

The at least one locking element then has a sloping side, which is oriented at an acute angle to the third contact surface and on which a support surface is formed, wherein the at least one locking element on a corresponding oblique side of the first contact element or the second contact element or a further locking element supported, which is oriented parallel to the oblique side of the at least one locking element. As a result, a spacer device can be realized in a simple manner and in particular thread-free, which detects a displacement position relative between the second contact element and the first contact element. This shift position is in turn variable detectable. Furthermore, the corresponding investment device can be realized in a simple manner and in particular realized completely made of plastic.

The abutting sloping sides are provided with a profiling. The profiling is, for example, a wave structure. For example, if a wave crest of a sloping side in a trough of a
is immersed supporting sloping side, then a self-locking is achieved.

In one embodiment, it is provided that the at least one locking element or a further locking element is guided linearly displaceable on the second contact element. As a result, an additional stabilization of the investment device is achieved and it can thereby also reduce a game.

In particular, it is provided that the at least one locking element forms a spacer between the second contact element and the first contact element, which defines the distance between the second contact surface and the third contact surface at least in one direction. The determination, which is variable, is then achieved not by a thread or the like, but by one or more movable spacers.

In a further embodiment, the at least one locking element is rotatably mounted on the second contact element. By setting a certain rotational position of this locking element can then determine a displacement position between the second contact element and the first contact element.

In such an embodiment, the abutment device can be realized with a minimized number of components. In principle, the system can be realized with only three separate components, namely the first contact element, the second contact element and the rotatable locking element. Respective members for holding the second abutment member on the first abutment member, for holding the rotatable locking member, for the relative sliding movement of the second abutment member and the first abutment member, for displacing the displacement between the first abutment member and the second abutment member, and for detecting the distance may be integrally attached the corresponding component (first spacer, second spacer, rotatable locking element) may be arranged.

An eccentric device is provided, by means of which a linear displacement of the second abutment element relative to the first abutment element can be actuated fixedly by turning the at least one locking element. Due to the eccentric device, a rotary movement can be converted into a linear movement. With appropriate design of the eccentric can be achieved at the same time a commitment.

The eccentric device is self-locking, so that a relative displacement position between the second contact element and the first contact element is fixed by a specific rotational position of the at least one locking element. Such a self-locking training can be achieved, for example, in a simple manner, when the eccentric comprises a spiral like logarithmic spiral.

An eccentric guide track for at least one engagement element is arranged on the at least one locking element or the first contact element, wherein the at least one engagement element is seated on the first contact element or the at least one locking element. It is characterized formed a slide track, which on the one hand ensures the displacement movement and in which on the other hand, a determination is formed with a corresponding adjustment of the engagement element and the guideway.

The eccentric guideway is a spiral path. This makes it easy to achieve a self-locking effect.

The system can be solved in a simple manner: After fixing the bottom element, the at least one contact device is removed upwards, wherein in particular a possible tension of the contact device between wall and floor element by loosening the detection and / or change the position of the second contact element to the first Investment element is solved. The tension can be canceled in a simple manner by acting on the investment device.

A first embodiment of a system according to the invention, which in the FIGS. 1 to 5 shown and designated therein by 10, comprises a first contact element 12 and a second contact element 14. The first contact element 12 has an L-shaped cross-section (cf. FIG. 4 ) with a first contact surface 16 and a second contact surface 18. The first contact surface 16 is formed on a first region 20 of the first contact element 12. The second contact surface 18 is formed on a second region 22 of the first contact element 12. The first region 20 and the second region 22 are in particular integrally connected to one another.

The second contact surface 18 lies transversely and in particular perpendicular to the first contact surface 16. The second region projects beyond the first region 20.

In one embodiment, the second contact surface 18 is provided with a profiling 24. This profiling is formed for example by a wave structure.

The first contact surface 16 and the second contact surface 18 intersect in a line 26.

The first contact element 12 has a recess 28 on a side opposite the first contact surface 16. This recess 28 is toward an upper side in a direction of the surface normal of the first abutment surface 16 open. It is bounded laterally and rearwardly by an edge 30, wherein the edge 30 has mutually opposite opposite lateral edge elements 32a, 32b and a rear edge element 34. The rear edge element 34 is connected to the lateral edge elements 32a, 32b and arranged in a region of the second contact element 12, which faces away from the second region 22 with the second contact surface 18.

To the front, on a side opposite the rear edge element 34 side, in continuation of the second region 22, the recess 28 is open.

The recess 28 has, for example, the shape (at least approximately) of a hollow cuboid.

The first contact element 14 is arranged in the recess 28 and guided linearly displaceable on this. A displacement direction 36 is transverse and, for example, at least approximately perpendicular to the second contact surface 18 and at least approximately parallel to the first contact surface 16. For example, the deviation from the exact parallelism is at most 10 °.

The first contact element 14 is preferably arranged and formed such that an upper side 38 of the second contact element 14, which faces away from the first contact surface 16, does not protrude beyond the edge 30 in a height direction 40 (which is a normal direction to the first contact surface 16) and, for example, is flush with a corresponding top 42 of the rim 30.

The second contact element 14 has a third contact surface 44. This third contact surface 44 is oriented transversely and in particular perpendicular to the first contact surface 16. The third contact surface 44 is at least approximately parallel to the second contact surface 18 of the first contact element 12 by a corresponding relative positioning of the second contact element 14 relative to the first contact element 12 in the displacement direction 36 is a distance between the third bearing surface 44 and the second bearing surface 18 adjustable.

Guiding recesses 46a, 46b are respectively formed on the lateral edge elements 32a, 32b. These guide recesses 46a, 46b are formed for example as grooves. A guide recess 46a, 46b is bounded in each case by a ceiling strip 48a, 48b upwards (away from the first contact surface 16).

It is basically possible for the guide cutouts 46a, 46b to be continuous on the rear edge element 34 and to extend, for example, over the entire length of the corresponding lateral edge element 32a, 32b from the front to the rear edge element 34. It is also possible that the guide recess 46a, 46b are shorter than the said length. It is furthermore possible for a plurality of guide recesses 46a ', 46a "or 46b', 46b" to be arranged on the corresponding lateral edge element 32a, 32b, which are spaced apart from one another (cf. FIG. 2 ).

In one exemplary embodiment, the ceiling strip 48b is bevelled on a side 50 facing away from the first contact surface 16, wherein a height in the height direction 40 of the ceiling strip 48b decreases away from the lateral edge element 32b. This chamfer on the side 50 is an import facilitation of a strip member 52b of the second abutment member 14 in the associated guide recess 46b when manufacturing the abutment device 10th

The second contact element 14 has a ceiling element 54, which is at a distance from the first contact element 16. On the ceiling element 54, a plurality of ribs 56 is arranged in particular in one piece. Via the ribs 56, the second contact element is supported on an upper side 58 of the first contact element 12, the upper side 58 being opposite the first contact surface 16.

In particular, the upper side 58 of the first contact element 12 is oriented parallel to the upper side 38 of the second contact element 14.

On the lid member 54 outer ribs 60a, 60b are arranged. The outer rib 60a is associated with the lateral edge element 32a and directly adjacent to this. The outer rib 60b is directly adjacent to and associated with the lateral edge member 32b. On the outer rib 60a sits a strip element 52a, which is immersed in the ceiling recess 48a in the guide recess 46a. The strip element 52b is seated on the outer rib 60b and is immersed in the ceiling recess 48b in the guide recess 46b.

The second abutment element 14 may laterally be provided in each case with a strip element 52a or 52b, or a plurality of lateral strip elements 52a ', 52a "or 52b', 52b" may be present.

The ribs 56 and the strip elements 52a, 52b in relation to the guide recesses 46a, 46b and ceiling strips 48a, 48b are dimensioned so that a linear guide and in particular sliding of the second contact element is realized on the first contact element 12 in the displacement direction 36. Via the ceiling strips 48a, 48b, a lift-off in the height direction 40 for the second contact element 14 with respect to the first contact element 12 is made.

The second abutment element 14 is closed in a front region 62, so that the ribs 56 are pushed forwards through walls 64 (see, for example, FIG FIG. 2 ), which are oriented transversely to the ribs 56, are covered. At this front region 62 on an outer side of the walls 64, in turn, the third contact surface 44 is formed. This third contact surface 44 is preferably closed (simply connected).

The second contact element 14 is in the manner of a drawer on the first contact element 12 detectable (see below) in the direction of displacement 36 slidably guided.

The second contact element 14 has a sloping side 66 facing the rear edge element 34. This oblique side 66 is oriented at an acute angle 68 to the line 26 or oriented in the acute angle 68 to a perpendicular to the displacement direction 36. The acute angle 68 is for example in the range between 15 ° and 30 °.

In one embodiment, a rear side 70 of the second abutment element 12, which faces away from the front region 62 and faces the rear edge element 34, has the oblique side 66, which merges into a side 72 which is oriented parallel to the line 26. The side 72 has a length which is substantially shorter than the length of the oblique side 66.

The oblique side 66 is provided with a profiling 74. This profiling 74 is formed for example by a wave structure.

By means of this locking device 76, a relative displacement position between the second contact element 14 and the first contact element 12 in the displacement direction 36 can be determined in such a way that at a set relative position between the second contact element 14 and the first contact element 12, the second contact element 14 can not be moved in the direction of the rear edge element 34. (As will be explained in more detail below, the second abutment element 14 can in principle be made to slide away from the rear edge element 34, this does not restrict the operation of the abutment device 10.)

The locking device 76 includes a locking element 78. In the conditioning device 10 exactly one locking element 78 is provided. This locking element 78 is formed as a wedge element. It is arranged linearly displaceable in a direction 80 between the second contact element 14 and the edge 30, wherein this displacement direction 80 is transverse and in particular perpendicular to the displacement direction 36.

The locking element 78 has a first side 82 and an opposite side 84. The sides 82 and 84 are parallel to each other and are oriented parallel to the lateral edge elements 32a, 32b. The side 82 and the side 84 are connected by a side 86 which is oriented parallel to the displacement direction 80 and is oriented parallel to the rear edge element 34. This side 86 is closest to the rear edge element 34. The sides 82 and 84 are further connected by a sloping side 88. This oblique side 88 is oriented parallel to the oblique side 66 of the second contact element 14. The oblique side 88 is supported on the sloping side 66. The inclined sides 88 and 66 form support surfaces for supporting the second contact element 14 on the locking element 78.

On the inclined side 88, the locking element 78 is provided with a profiling 90. The profiling 90 is formed for example by a wave structure.

The profiles 74 and 90 are adapted to each other in such a way that when the oblique side 88 is supported on the oblique side 66, a kind of self-locking effect is achieved; For example, if a mountain of the profiling 90 is immersed in a valley of the profiling 74, then a force is needed to lead out such a mountain from the valley. Without provision of such a force can then be the locking member 78 does not move in the direction of displacement 80. (By advancing the second contact element 14 away from the locking element 78, the "hooking" of the profiling 90 with the profiling 74 can be overcome in a simple manner.)

The locking element 78 has between the sloping side 88 and the side 86 lying webs 92a, 92b. These webs 92a, 92b are gripping webs on which an operator can engage the locking element 78 in order to displace it in particular in the direction of displacement 80.

The web 92a rises above troughs 94b, 94c; the web 92b rises above a depression 94a and the depression 94b. The locking element 78 then does not protrude beyond the edge 30, in particular in the height direction 40.

It is alternatively also possible that the webs 92a, 92b are arranged projecting beyond an upper side of the locking element 78.

The webs 92a, 92b are in particular integrally formed on the locking element 78.

It is basically possible that only one web is provided or that more than two webs are provided.

The locking element 78 is slidably guided on the first contact element 12. For this purpose, a guide device 96 is provided. The guide device 96 has a guide rail 98, which is oriented parallel to the displacement direction 80 and is arranged on the upper side 58 of the first contact element 12 uplifting thereon.

The locking element 78 has a corresponding guide recess (guide groove) 100 (cf., for example FIG. 4 ) by means of which the locking element 78 is placed on the guide rail 98, wherein the guide rail 98 is immersed in the guide recess 100. A lower side 102 is supported on the upper side 58 of the first contact element 12 and slidably guided on it.

The guide device 96 further includes one or more guide recesses 104 (see, for example, FIG FIG. 4 ), which the rear edge element 34 facing. A corresponding guide recess 104 is formed in particular as a groove.

On the rear edge element 34 one or more tabs 106 are arranged, wherein a tab 106 is inserted into a corresponding guide recess 104. Such a tab 106 provides a lift-off protection of the locking element 78 in the height direction 40 relative to the first contact element 12 ready.

The (at least one) guide rail 98, which is oriented in the displacement direction 80, provides for the actual linear guide of the locking element 78 in this direction. The guide recess or guide recesses 104 in correspondence with the corresponding lugs 106 provide a lift-off protection and also for a linear guide in the region of the rear edge element 34.

It can also be provided that the locking element 78 is guided via a corresponding guide device on the second contact element 14.

For example, for this purpose, the locking element 88 comprises a foot 108 which is slidably guided on the upper side 58 of the first contact element 12 (see FIG. 4 ). The foot 108 is disposed on the sloping side 66 and extends to the second abutment member 18 back.

At the foot 108, a recess 110 is formed. In this recess 110, a dipping element 112, which is arranged on the inclined side 66 of the second contact element 14, immersed. Via the recess 110 and the immersion element 112, a guide device is formed, through which the locking element 78 is guided linearly displaceable on the second contact element 14, wherein this guide means is formed so that the displacement along the displacement direction 80 is not hindered.

The ribs 56 are arranged and designed so that the foot 108 can be pushed past them (see. FIG. 2 ), that is, the ribs do not extend to the immersion element 112 but have a respective end 114, which faces the oblique side 66, while the immersion element 112 is spaced such that the foot 108 of the locking member 78 can be guided past them.

The second abutment element is supported on the locking element 78 by direct contact of the oblique sides 66 and 88. The locking element 78 in turn is supported on the first contact element 12 via the guide device 96. In principle, the locking element 78 can also be supported on the rear edge element 34.

The investment device according to the invention functions as follows:
When laying floor elements (in particular floor panels), in the case of a first row of floor elements 116 close to the wall (cf. FIG. 1 ), depending on the circumstances a certain distance to a wall 118 are met. By one or more inventive attachment devices 10, such a distance can be set in a simple manner defined. An investment apparatus 10 is a laying aid for example parquet panels or laminate panels. For example, a use for stone elements or ceramic elements is possible, etc.

For this purpose, the contact device 10 is placed on the wall-near bottom element 116, in such a way that the first contact surface 16 is placed on an upper side of the wall-near bottom element 116 and the second contact surface 18 abuts against an end face 120 of the wall-near bottom element 116, said end face 120 of Wall 118 faces.

In FIG. 1 a basic position of the second contact element 14 is shown. The second contact element is not pushed out there relative to the first contact element 12.

To set a certain distance D, the second contact element 14 is now pushed forward relative to the first contact element 12, in the direction of the wall 118. This can be done directly or via a movement of the locking element 78 in the displacement direction 80. The defined distance D is adjusted by positioning the locking element along the displacement direction 80. The locking element 78 secures by its position this particular distance D. The second contact element 14 is supported on its oblique side 66 on the locking element 78 and this in turn on the first contact element 12. Thus, this distance D can not be increased, that is the second Abutment member 14 can not be moved in the direction of the rear edge member 34, unless the locking member 78 is moved. The locking element 78 forms a spacer between the second contact element 14 and the first contact element 12 and in turn the distance D is fixed.

After fixing the wall-near bottom element 16, the investment device 10 can be removed upwards. If this is braced with the wall 118 and the bottom member 116, this tension can be solved in a simple manner by the locking member 78 is moved accordingly, so that the distance D can be increased. The abutment device 10 can then be pulled upwards.

The investment device 10 is compact. Through them can be set in a defined manner, a wall distance, for example, a near-wall floor element 116 and this distance near the wall can be set in a simple manner. Furthermore, even with a clamping of the abutment device 10 between the wall 118 and the floor element 116 near the wall, the abutment device can be released in a simple manner.

The foot 108 also provides a release fit of the second abutment member 14 to the first abutment member 12 in the translation direction 36.

A second embodiment of a system according to the invention, which in the FIGS. 6 to 11 is shown, in turn, comprises a first abutment element 124 and a second abutment element 126, which can be fixed in a displaceable manner. The second abutment element 126 is lockably displaceable relative to the first abutment element 124 in the displacement direction 36.

In contrast to the second contact element 14 of the abutment device 10, the second abutment element 126 has no oblique side 66, but a side 128 which faces a rear edge element 128 (corresponding to the rear edge element 130 of the abutment device 10) and at least approximately parallel to this rear edge element 130 is oriented; In particular, the side 128 is oriented at least approximately parallel to a direction perpendicular to the displacement direction 36. A locking device 132 for fixing the second contact element 126 on the first abutment element 124 in a specific displacement position such that the distance between the side 128 and the rear edge element 130 is set such that this distance can not be reduced.

The locking device 132 comprises a first locking element 134, which is designed as a wedge element, and a further, second locking element 136, which is likewise designed as a wedge element. The second contact element 126 is supported on the second locking element 136. This in turn is supported on the first locking element 134 and the first locking element 134 is supported on the first contact element 124.

The first locking element 134 has a side 138 which is aligned parallel to the rear edge element 130. It also has an opposite side 140, which is a sloping side and oriented at an acute angle to the line 26. The second locking member 136 has a side 142 which faces the side 128 of the second abutment member 126 and is directly adjacent thereto. It has an opposite inclined side 144. This oblique side 144 is parallel to the oblique side 140 of the first Locking element 134 aligned. The oblique sides 140 and 144 form support surfaces, via which the second locking element 136 is supported on the first locking element 134. In this case, a profiling according to the profilings 74, 90 can be provided.

The first locking element 134 and the second locking element 136 are each displaceable in a displacement direction 146, wherein the displacement direction 146 is transverse and in particular perpendicular to the displacement direction 36. The displacement direction 146 is in particular parallel to the line 26, in which the first contact surface 16 and the second contact surface 18 meet. (The same reference numerals are used for the same elements as in the abutment device 10.)

The second abutment element 126 is provided with a lower surface 148 (see, for example, FIG FIG. 10 ) is placed on a corresponding upper side 150 of the first contact element 124, that is based on this from and slidably guided. The second contact element 126 comprises a first region 152 and a second region 154 adjoining the first region. The first region 152 and the second region 154 are in particular integrally connected to one another. At the first region 152, the third contact surface 44 is arranged. At the transition from the first region 152 to the second region 154, the side 128 lies. The first region 152 has a greater height in the height direction 40 than the second region 154. This results in a corresponding transition from the first region 152 to the second Area 154 formed a step 156. The step 156 lies on an upper side 158 of the second contact element 126 applied to the lower side 148.

One end 160 of the second region 154 abuts against the rear edge element 130 in a basic position of the second abutment element 126 relative to the first abutment element 124.

It can be provided that the second region 154 on its outer side with respective ends 160 a stop surface for the rear edge element 130, these ends being formed on tabs 161. Between these tabs 161 is a free space 163, which is used for example for a part of a guide device of the first locking element 134.

On opposite lateral edge elements 162a, 162b (see for example FIG. 11 ) of the first contact element 124 ceiling strips 164a, 164b are formed. These limit guide recesses 166a, 166b. In these guide recesses 166a, 166b, the second contact element 126 is immersed with its second portion 154. It is characterized provided a linear guide and a lift-off in the height direction 40th

For example, one or more tabs may also be arranged on the first region 152, which inserts corresponding guide recesses on the lateral edge elements 162a, 162b.

The first locking element 134 and the second locking element 136 are guided in parallel sliding sliding. The second locking element 136 rests with a lower side 168 on the corresponding upper side 150 of the second region 154 and is thereby supported on the second contact element 126. On the second locking element 136, a slider 170 is laterally outstanding. This slider 170 has penetrated through an opening 172 in the lateral edge member 162b. A bottom of the slider 170 is part of the bottom 168.

Via the slide 170, which is arranged on the longer transverse side of the second locking element 136, the second locking element 136 is guided in the opening 172. Furthermore, the second locking element 136 is slidably guided on the second region 154 via its underside 168.

Furthermore, a guide of the second locking element 136 is provided on the second contact element 126. For this purpose, the second locking element 136 comprises, for example, a guide recess 174, which has an extension direction parallel to the displacement direction 146. The second investment element 126 has in the region of the step 156 (on the side 128) on a guide bar 176, which is immersed in the guide recess 174 and is formed with an undercut tab 178 so that when ensuring the guide, the second abutment member 126 is not of the second locking element 136th based on the displacement direction 36 can be solved. The undercut tab 178 provides a release lock of the second abutment member 126 relative to the second immobilizer member 136 for the direction 36.

The first locking element 134 also has a slider 180. This has penetrated through an opening 182 in the lateral edge element 162a. The slider 180 and the slider 170 are positioned on different lateral sides of the abutment 122. By the slider 180 in the opening 182, in turn, a linear guide of the first locking element 134 is provided. This is also slidably guided on the second region 154 of the second contact element.

The oblique side 140 is aligned parallel to the oblique side 144 and supported on this. By setting a specific displacement position in the displacement direction 146 of the first locking element 134 and the second locking element 136, the distance of the side 128 to the rear edge element 130 can be determined and thus the protruding out of the third contact surface 44 beyond the first contact element 124 can be set.

The second contact element 126 is dimensioned with the second region 154 in such a way that even with the maximum extraction of the second contact element 126 in the direction 36 relative to the first contact element 124, the first locking element 134 still partly rests on the second region 154 (cf. FIG. 8 ).

On the rear edge element 130 and / or on the second contact element 126 in the region of the rear edge element 130 and in particular in the free space 163, when the second contact element 126 with the ends 160 on the rests against the rear edge element 130, guide shoes 184 are arranged. A corresponding guide shoe has a guide recess 186, in which one or more guide strips 188 of the first locking element 134 are immersed. A guide strip 188 has an undercut tab 190. About the guide bar or guide rails 188 and the guide shoes 184, the first locking element 134 is linearly guided in the displacement direction 146 on the second contact element 126 in the region of the rear edge element, namely slidably guided. The undercut tab or undercut tabs 90 provide that, when the guide rail 188 is immersed in the corresponding guide recess 186 of a guide shoe 184, the first locking member 134 is secured forward in the direction of displacement 36 against loosening.

The locking elements 134 and 136 are provided with gripping ridges as described in connection with the abutment device 10.

The attachment 122 functions as follows:
In a basic position of the investment device 122, which, for example, in FIG. 7 is shown, the second abutment member 126 is displaced so that it does not protrude beyond the first abutment member 124 and the displacement direction 36. For example, the tabs 161 then abut against the rear edge element 130 with their ends 160. The first locking element 134 and the second locking element 136 are in a basic position.

When the first locking element 134 is displaced in the direction of the lateral edge element 162b and the second locking element 136 in the direction of the lateral edge element 162a ( FIG. 8 ), then the distance between the sides 142 and 138 increases. As a result, the second abutment element 126 is displaced outward in the displacement direction 36 (FIG. FIG. 8 ). The particular position is by supporting the second abutment element 126 via the side 128 on the second locking element 136, which in turn is supported on the first locking element 134 and which in turn is supported on the first contact element 124, found.

By adjusting certain displacement positions of the first locking element 134 and the second locking element 136, certain distances between the third contact surface 44 and the second contact surface 18 can be determined detectable, wherein the determination with respect to a pushing of the second contact element 126 to the rear edge element 130.

Otherwise, the abutment device 122 functions as described above with reference to the abutment device 10.

A third embodiment of a system according to the invention, which in the FIGS. 12 to 16 shown and designated there by 192, in turn, comprises a first contact element 194 with first contact surface 12 and second contact surface 14. At the first contact element 194, a second contact element 196 is guided with a third contact surface 44 like a drawer.

The relative position of the second contact element 196 and thus of the third contact surface 44 to the second contact surface 14 is detectably displaceable via a locking device 198. The locking device 198 in turn comprises a locking element 200. This locking element 200 is designed as a knob. The locking element 200 is a rotary knob 202. It is rotatably mounted in a cylindrical recess 204 of the second contact element 106 in the manner of an outer shaft with an axis of rotation 206 which is transverse and in particular perpendicular to the displacement direction 36.

The knob 202 has an edge 208 which is cylindrical. This edge 208 is above a top 210 of the knob 202. Connected to the edge are grip webs 212, which are arranged, for example, in a cross shape with respect to one another and via which an operator can grip the rotary knob 202 to a rotary actuation.

The first contact element 194 has a recess 214 in which the second contact element 196 is guided. In the recess 214, an engagement member 216 is disposed in a front region. This engagement element protrudes beyond a bottom 218 of the recess 214. The engagement member 216 has a curved first side 220 and a curved second side 222.

The knob 202 has the bottom 218 of the recess 214 facing a guideway 224. The engagement member 216 is immersed in the guideway 224.

The knob 202 is provided with an eccentric 226. This eccentric device 226 is formed by means of the guide track 224. By a rotation on the knob 202 is a linear movement of the second abutment member 196 relative to the first abutment member 194; this is shifted in the direction of displacement 36.

The guideway 224 is a spiral path. It is formed for example by means of a logarithmic spiral. Such a spiral has a self-locking effect. If a certain rotational position of the knob 202 is set, then also a shift position of the second abutment member 196 is detected to the first abutment member 194.

The attachment 192 functions as follows:
In FIG. 15 a basic position is shown in which the first abutment element 196 is displaced rearwardly with respect to the first abutment element 194; There, the third contact surface 44 and the second contact surface 18 at a minimum distance.

By turning the knob 202, the guide track 224 is displaced relative to the engagement member 216. The engagement element 216 is designed in this way that at each position within the guideway 224 with the first side 220 and the second side 222 abuts on boundaries of the guideway 224 and thus there is a minimized game (see. Figures 14 and 15 ). The guideway 224 is eccentric. The rotation causes a displacement of the second abutment element 196 relative to the first abutment element 194. This increases the distance between the third abutment surface 44 and the second abutment surface 18 (see FIG. Figures 12 and 14 ). At the same time by the engagement of the engaging member 216 with the first side 220 and the second side 222 at a boundary of the guideway and by the self-locking design of the eccentric 226 determined the particular displacement position.

Otherwise, the abutment device 192 functions as described above with respect to the abutment device 10 and 122.

It is also possible in principle for the engagement element 216 to be arranged on the rotary knob 202 and for the corresponding guide track 124 to be arranged on the first abutment element 194.
