Description

Wood connection, use of a wood connection and handrail with such a wood connection

The invention relates to a wood connection, in particular a wood connection for connecting longitudinally abutting wooden parts, wherein it is in particular parts of a handrail in the abutting wooden parts. The invention also relates to the use of such a wood connection for connecting longitudinally abutting wooden parts, in particular sections of a handrail and a handrail with at least one such wood connection.

Wood connections for handrails are well known. From DE 201 15 726 a wooden connection is known in which the abutting portions of a handrail each have a central coaxial blind bore into which a central common connecting element engages and wherein the abutting ends additionally each have at least one coaxial annular groove in the one further common in cross-sectionally annular connecting element engages.

Further connecting elements for handrails are known from DE 203 00 287, DE 202004 020 569 and DE 20 2005 012 422. In addition, connecting elements for handrails are also known from DE 102 31 250 and DE 20 2004 010 428. In addition, reference is made to the prior art according to the following documents: DE 297 04 031; DE 198 11 751; DE 200 04 787; DE 299 22 759; DE 101 00 403 and DE 10 2004 020 637. A disadvantage of these known devices is especially the difficulty in the adjustment of the wood parts to be joined of the handrail to each other, so that a desired continuous continuation, the so-called "Schmiege" results, without causing undesirable gaps between the wood parts.

Accordingly, it is an object of the inventors to provide a further embodiment of a wood connection, the use of such a wood connection and a handrail with such a wood connection, in which the abovementioned disadvantages are avoided or at least reduced with regard to their effect.

This object is achieved with the features of claim 1. For this purpose, in a wood connection with a first and a second abutment and a combined with the first and second abutment clamping means, in particular a threaded rod, provided that the clamping means at least one time a closing element and arranged between the closing element and abutment abut or arrangeable, in the longitudinal direction of Chuck is associated with compressible spacer element. Each abutment is provided for combination with a respective portion of the wood elements to be joined. The or each abutment is captively combined with the respective wooden part, e.g. by screwing, gluing or the like. Each abutment passes through the tensioning means, e.g. the threaded rod, applied tensile load in the respective wooden part.

The advantage of the invention results from the use of the compressible spacer element. Without the use of such a spacer element, for example when screwing a threaded rod into two wooden parts to be joined together, oppositely introduced abutments can result that the end faces of these wooden parts abut one another without the desired transition from the first to the second wooden part being established. This is usually irrelevant in straight wood parts, if you do not have to pay attention to pre-drilling for rods, fittings or the like or to a largely without continuation of the continuation of the wood grain. In the case of bent wooden parts, however, it is indispensable that a bent piece of wood, with a certain course of its curvature, adjoin another straight or likewise bent piece of wood. In other words: With a handrail, it is essential that the handrail follows in its course, for example, the course of the associated staircase. If, in the above-outlined screwing in of a threaded rod into two abutments, the front sides of the respective wooden parts meet one another and the curved wooden part projects into the course of the staircase, This is an unsatisfactory situation that has been circumvented at best by the fact that the screw is partially released again and the bent wood part is aligned in the desired direction. Other known types of connection have similar disadvantages. These and other disadvantages are avoided by the invention by the use of the spacer element.

By the spacer element results in a firm connection between the wood parts to be joined as soon as all participate in the wood connection components, so the clamping means with at least one abutment, the closing element with the clamping element and the spacer element and this in turn with the remaining abutment, engage with each other. Due to the compressibility of the spacer element, however, the wood connection can be tightened even further, so that the desired orientation of the participating wood parts can be achieved even with already solid wood connection.

The subclaims relate to preferred embodiments of the invention.

According to a first preferred embodiment, it is provided that the first abutment has a female thread matching the threaded rod. The second abutment is designed as a sleeve. The inner diameter of the sleeve is chosen so that a passage of the threaded rod is possible. The terminating and the spacer element are located at least on the side of the sleeve designed as an abutment. Both abutments can thus be used when using the wood connection in each case a wooden part, for example, be screwed. To accommodate the end and the spacer element, the wood part, which is associated with the designed as a sleeve abutment, a recess, in particular an axle bore, which is provided in depth for receiving the abutment and the terminating and the spacer element. To mount such a wood connection, therefore, the wood connection is first opened by the an inner thread having abutment - the first abutment - is released from the threaded rod and is inserted into one of the wooden parts. The other, second abutment is combined with inserted threaded rod with the other wood part. As a final element is a mother, a screw head, a splint or the like into consideration. When using a screw head as the end element, the threaded rod is the threaded part of a screw with such a screw head. After the two parts i of the wood connection are inserted into the respective wooden parts, the threaded rod protrudes (the corresponding abutment of one of the wooden parts - the above-mentioned second abutment - forth out. The threaded rod is then inserted into the internal thread of the first abutment and constructed the connection by the threaded rod is screwed into the first abutment. As soon as the faces of the two pieces of wood abut each other, the closing element comes with the spacer element and this in turn with the lying in the interior of each wood part surface of the sleeve designed as an abutment - the second abutment - in permanent contact, so that the second abutment begins by means of Gewindestabs applied tensile load. If, in this situation, the orientation of the two wooden parts to one another is not yet present in the desired manner, the threaded rod can be screwed further into the internal thread of the first abutment. The distance element is pressed together around the path covered in the process. It has been found that with a suitable selection of material for the spacer element, for example rubber, at least one complete revolution of the threaded rod in the internal thread of the first abutment is still possible. With such a possible complete rotation of the threaded rod, any orientation of the two wooden parts to each other can be achieved. The wooden parts remain during this further rotation on their front sides in firm contact, which does not dissolve again during the existence of the wood connection.

Another embodiment of the above-described specific embodiment of the wood connection is that the first and second abutment are designed as a sleeve and accordingly allow passage of the threaded rod. Then, the threaded rod on both sides in each case a spacer element and at least one side associated with a closure element. This wood connection is based on the same inventive principle as the wood joints described above, namely by allowing the spacer element further actuation of the threaded rod, even if the end faces of the wood parts to be joined already come to rest on each other. The solution in which both abutments are designed as a sleeve, above all, has a manufacturing advantage, namely that only the same parts are required for the wood connection, namely a threaded rod, two mutually identical abutment and two identical end elements, e.g. Threaded nuts or the like, as well as at least one spacer, with two spacers two mutually equal spacers.

A particularly simple and also detachable combination of the above-described abutment with the respective wooden part is possible if each abutment has an external thread. The abutment can then easily in a designated, at round Wood parts are screwed on the end face of the wood part centered hole. An example of such an abutment with an external thread is an abutment in the manner of a Rampra screw, which has recesses for the approach of a blade of a screwdriver and thus allows screwing into the respective wooden part.

Another alternative embodiment of the wood connection is characterized in that each abutment is disc-shaped, wherein the disk-shaped abutment is provided for attachment to one end face of the two wood parts to be joined. Such disc-shaped abutments have at least one central bore, which allows a passage of the threaded rod. When using such a wood connection, each disc-shaped abutment is mounted on the end face of the respective wooden part so that the center hole is centered on the front side. When mounting the wood connection of the threaded rod with the terminating and the spacer element remains assigned to one of the disc-shaped abutment, wherein the terminating and the spacer member mounted disc-shaped abutment in a provided in the wood part and covered by the abutment recess, in particular a blind bore added are. From the wooden part thus protrudes through the central bore of the abutment of the threaded rod. When combining the wooden parts, the threaded rod is inserted through the central bore of the other abutment, where it is e.g. engages in a combined with the abutment thread.

If the threaded rod is assigned on both sides in each case a spacer and a terminating element, the same effect as described above is produced in principle during the production of the connection, however, such a connection again has the advantage that only mutually identical components are required, namely two mutually equal abutments, a threaded rod, two identical end elements, such as a threaded nut or the like, and at least one spacer element, optionally also two and then mutually equal spacer elements. Such a wood connection is made by the wood connection is first opened by removing at least one end element by a disc-shaped abutment is then combined after insertion of the dissolved end element in a designated recess of a wood part with this wood part, for example by screwing. The remaining parts of the wood connection, so the further disc-shaped abutment and the closing element still in connection with the threaded rod are introduced together with the spacer into a recess of another piece of wood and the disc-shaped abutment with the wood part, eg also by screwing combi ned. Then protrudes from the wood part through the central bore of the disk-shaped abutment of the threaded rod out, which is inserted through the central bore of the other abutment in the local end element and, as soon as an engagement in the thread, can be screwed. The connection results from further rotation of the wood parts to each other, wherein the threaded rod is screwed into at least one of the end elements. Once the faces of the wooden parts or the surfaces of the disc-shaped abutment come into contact with each other, the wood connection is fixed, with further screwing the threaded rod in at least one end element under compression of the or each spacer element remains possible, so that the desired orientation of the wooden parts is accessible to each other ,

When using disc-shaped abutment has been found to be advantageous to arrange the respective end element and optionally a spacer in a holding cage. In this case, such a holding cage is assigned to the disc-shaped abutment, so for example. integrally formed or welded to metallic elements. The holding cage ensures a fixation of the closing element at least insofar as its thread is accessible through the central bore of the disc-shaped abutment. For this purpose, it can be provided in a particularly preferred embodiment that the holding cage at its open end a flexible fixing element, e.g. has one or more deformable by bending tabs. Alternatively or additionally, it may be provided that the retaining cage is matched with respect to its inner contour to the outer contour of the end element. In the case of a threaded nut as a closing element, the hexagonal inner contour also has correspondingly the retaining cage.

An embodiment that has proven to be advantageous in connection with so-called screed handrails, ie handrails in which the wooden parts have a rectangular cross-section, is characterized in that each disk-shaped abutment at least a first bore for receiving an adjusting element and at least one Having second bore for receiving a fastener. As adjustment and fastening element are preferably different sized screws used. With a screw acting as an adjustment first screw so the disc-shaped abutment can be adjusted on the front side of the respective wooden part and fixed for further assembly. For this purpose, for example, by means of a matched to the end face of the wood part and the disk-shaped abutment Schablohne introduced into this face Vorbohrungen be used. Such pilot holes prevent unwanted displacement of the disc-shaped abutment when Tighten the or each screw acting as the adjusting element. Once the disk-shaped abutment is adjusted and fixed with the adjusting element, a fastener, so in particular a larger sized screw can be introduced through the second bore, which penetrates into the solid material of the wood part or in a suitable in view of the expected tensile forces in their diameter selected Pre-drilling is introduced.

In a screed handrail, so a handrail with wooden parts with rectangular or substantially rectangular cross-section, the term disc-shaped abutment does not necessarily mean a disc with a round contour but generally a flat element. As a form of such a disk-shaped abutment, an element with a likewise rectangular or substantially rectangular envelope contour results, which may optionally be rounded at its short sides. A guided through a second bore of such a disc-shaped abutment fastener protrudes in a particularly preferred embodiment through the respective end element through. Thus, the fastener effects an adjustment of the end member, e.g. undesired rotation of the closing element or tilting of the closing element, such that its internal thread is no longer accessible through the central bore of the disc-shaped abutment, is avoided.

According to a further preferred embodiment, it is provided that one or each abutment has two first bores and two second bores, and that the center bore and the two first and second bores are arranged along a line or at least substantially along a line. When attaching such a wood connection each disc-shaped abutment is mounted on the end face of the respective wooden part so that the center of the central bore coincides with the centroid of the end face of the respective wooden part, so that when making the connection, so when turning the two wooden parts to each other, at least After each complete revolution, there is an aligned transition between the parts of the bowl handrail. If the two first and the two second holes are arranged along a line through the central bore in the abutment, preferably parallel to the longitudinal axis of the end face of the respective wooden part, it is ensured that the or each fastener and the or each adjusting element fully into the respective material of the Intervene wooden part. In particular, in the case of wooden parts which, due to their outer contour, represent a comparatively large lever with respect to the position of the threaded rod acting as a rotary axis, eg in screed handrails, it may be preferred that each disc-shaped abutment has a recess, for example a slot or the like, on its outer circumference , When making the connection, so when screwing the threaded rod in one or both end elements come at every full turn the recesses in both abutments to lie one above the other. Once the connection is fixed and the desired alignment of the wooden parts to each other, this alignment can be fixed by a pin or the like is inserted into the recess. With inserted pin is a rotation of the disc-shaped abutment to each other and thus also a rotation of the respective wooden parts to each other no longer possible.

To further improve or achieve a different visual appearance of the transition point between the two combined with the wood connection according to the invention wooden parts can be provided that in terms of its shape on the outer contour of both disc-shaped abutment and in terms of its height on the overall height of both disk-shaped abutment, in particular on the over the end face of the respective wooden parts remaining height of the disc-shaped abutment, tuned ring is used. Such a ring may also be deliberately used as a design element, e.g. in that the diameter of the ring is smaller than the diameter of the wood parts to be joined so that a shadow gap is established between the wood parts, at the bottom of which the ring, e.g. as a stainless steel element, remains recognizable.

1 shows a first embodiment of the wood connection 10 according to the invention. This comprises as clamping element a threaded rod 12, one end of which is designed as a closure element 14. Alternatively, the closing element can also be screwed onto the threaded rod 12 in the form of a threaded nut (not shown). In addition, the wood connection 10 comprises a first and a second abutment 16, 18. In the illustrated embodiment acts as a first abutment 16, a so-called ramp screw or an element in the manner of a Rampas screw. The first abutment 16 has an external thread 19 and a threaded rod 12 matching internal thread 20. The second abutment 18 is designed as a sleeve, wherein the resulting inner diameter allows passage of the threaded rod 12. Also, the second abutment has an external thread 21. In addition, a spacer element 22, for example a perforated disc in the manner of a rubber seal is provided. As indicated by the common center axis of all components of the wood connection 10, it is provided that the threaded rod 12 is passed through the spacer element 22 and the sleeve formed as a second abutment 18. The spacer element 22 is thus located between the end element 14 and the second abutment 18. With the so combined with the threaded rod 12 components of the wood connection 10 of the threaded rod 12 can be screwed into the internal thread 20 of the first abutment 16.

FIG. 2 shows an alternative embodiment of the wood connection 10 to the embodiment shown in FIG. 1. This wood connection 10 also has a threaded rod 12. The first and second abutment 16, 18 of this wood connection 10 are designed disk-shaped. They each have a central bore 24 and two lateral bores 26. As a final element 14 of this wood connection 10 two threaded nuts are provided. Between each end member 14 and the respective abutment 16, 18, a spacer element 22 is provided.

The described wood connections are in particular for the connection of wooden parts 30, 32 of a handrail, not shown, as it is assigned in a conventional manner stairs, balconies and the like, provided and the use of the illustrated in Fig. 1 wood connection 10 for connecting two Wood parts 30, 32 will be further explained below with reference to FIG. For receiving the wood connection 10, each wooden part 30, 32 has on its end face 34, 36 a recess 38, 40 in the form of an axle bore. In one of these recesses 38, 40, the first abutment 16 is screwed by means of its external thread 19. In the remaining recess 38, 40, the second abutment 18 is screwed by means of its external thread 21. However, the second abutment 18 is inserted with inserted threaded rod 12 (not shown in FIG. 3) and between the closing element 14 and the second abutment 18 located spacer element 22 in the respective recess 38, 40. To connect the two wooden parts 30, 32 is (the individual steps are not shown but only the resulting connected wood parts 30, 32 with the wood connection 10 used) of the projecting from the second abutment 18 threaded rod 12 in the internal thread 20 of the first abutment 16th introduced. Once the thread of the threaded rod 12 is in engagement with the internal thread 20 of the first abutment, the threaded rod can be inserted into the internal thread 20 of the first abutment 16. As soon as the end faces 34, 36 of the two wood parts 30, 32 abut each other, the wood connection 10 becomes solid. If the desired alignment of the wooden parts 30, 32 with respect to one another, for example in the case of at least one bent wooden part 30, 32, has not yet been achieved, the threaded rod 12 can be screwed further into the internal thread 20 of the first abutment 16. This is made possible due to the compressible spacer element 22. The increasing compression of the spacer element 22 allows at least one more further rotation of the threaded rod 12 in the first abutment 16. Thus, any desired orientation of the wooden parts 30, 32 to each other achievable.

Fig. 4 shows this in a schematically simplified form an end face 34 of a wood part 30 with inserted abutment 18, protrudes from the center of the threaded rod 12.

Fig. 5 and Fig. 6 illustrate the use of the wood connection according to Fig. 2, wherein Fig. 5 is a sectional view. In such a wood joint 10, each abutment 16, 18 is combined with one end face 34, 36 of the wood parts 30, 32 to be joined, e.g. in that the respective abutment 18 is screwed to the wooden part 30 by means of the lateral bores 26 and screws inserted therein. The combination with the wooden part 30, 32 takes place in such a way that the central bore 24 is centered on the respective end face 34, 36. Each abutment 16, 18 then covers the intended for receiving individual components of the wood connection recess 38, 40, which may not necessarily be executed in the wood connection according to FIG. 2 as an axle hole but also as a blind hole. In the interior of each recess 38, 40 is in existing wood connection 10 each have a closing element 14 and a spacer element 22, wherein a single, so only one-sided provided spacer element 22 is sufficient. The effect and the function of the wood compound 10 correspond to the effect and function described above.

In Fig. 5 and Fig. 6, a ring 42 is also shown, which is matched in shape to the outer contour of both disc-shaped abutment 16, 18 and in terms of its height to the overall height of both disc-shaped abutment 16, 18. The ring 42 serves, when the abutments 16, 18 are not sunk into the end face 34, 36 of the respective wood part 30, 32, to cover the otherwise visible portion of the wood connection 10. In a cross section of the ring 42 is smaller than the cross section of the respective Wood part 30, 32 results in a visually appealing shadow gap with the ring at the bottom of such a joint.

FIGS. 7, 8 and 9 show the use of the wood connection according to the invention in screed handrails, ie wooden parts 30, 32 having a rectangular or at least substantially rectangular cross-section, ie just such end faces 34, 36. FIG. 7 shows a longitudinal section through such screed handrail with two through the Wood connection 10 composite wood parts 30, 32 in a side view. 8 shows a view of the end face 34 of a wooden part 10 with the components of the timber connection located there. FIG. 9 shows the situation according to FIG. 7 in a view from above, and likewise in a sectional illustration.

The effect and function of the wood connection 10 in screed handrails correspond to the effect and function described above. Only with regard to the basically rectangular cross-section of such screed handrails, some special features are provided, which are explained below without going back to the previously described components, their function and arrangement and the like.

A difference between the wood connection 10 shown in FIGS. 7, 8 and 9 and the wood connection shown in FIGS. 5 and 6 is that disk-shaped abutments 16, 18 are no longer abutments with a round outer contour but with an elongated outer contour (cf. Fig. 8) are used. Basically, the contour of the or each abutment 16, 18, however, regardless of the cross section of the wood parts to be joined 30, 32. Only for static reasons, it has been found to be advantageous in screed handrails, the contour of the or each abutment the cross section of the respective wooden part 30, 32 approximate.

The introduced into the respective wooden parts 30, 32 recesses 38, 40 also have a contour corresponding to the cross section of the wood part 30, 32 and are expediently designed as a cutout. Accordingly, in the illustrated wood connection 10 as end elements 14, elongated end elements 14 are used, into which the threaded rod 12 is screwed when tightening the wood connection 10. Between each such elongated closing element on one side and indirectly or directly to the respective abutment 16, 18 on the other side of the spacer element 22 is provided, in principle, the arrangement of a spacer element 22 on only one side of the wood connection 10 is sufficient. On the abutment 16, 18 side facing the compressible spacer element 22 may still be provided intermediate member 44 that may also be integrally formed on the abutment 16, 18 or integrally with this. In such elongated components, in particular the final element 14, it has been found to be advantageous if provided for attaching the abutment 16, 18 provided on the respective wooden part screws (only schematically indicated by the imaginary center axis 46) through the end element 14. In this way, a correct alignment of the end element 14 allowing a contacting of the thread therein is directly achieved by the fixing of the respective components of the wood connection 10. guaranteed. In addition to the screws provided for fastening (fastener) are more screws as adjustment (also only schematically indicated by the imaginary center axis 48) provided. For the or each adjusting element, each abutment 16, 18 has first bores 50 and second bores 52 for the or each fastening element.

In Fig. 8 it can be seen that the two first and second holes 50, 52 along with the central bore 24 along a line, in particular the central longitudinal axis of the end face 34 of the respective wooden part 30 are arranged.

In Fig. 8 is also seen that each abutment may have on its outer circumference a recess 54 into which a pin or the like (not shown) can be inserted to a twisting of existing wood connection 10 up or abutting abutment 16, 18 to prevent. The ring 42 has in the embodiment for screed handrails one of the outer contour of the abutment 16, 18 corresponding basic shape. The ring 42 may itself have recesses 56 through which the recesses 54 in the abutment 16, 18 remain accessible even when attached ring 42. Without such recesses 56 in the ring 42 may need pins or the like in the recesses 54 in the abutment 16, 18 are used before attaching the ring. It can also be provided (not shown) that the ring 42 has on its inside shutdowns, which are intended for engagement in the recesses 54 in the abutment 16, 18.

Fig. 10 shows an embodiment of an alternative wood connection 58. This comprises a functionally substantially the threaded rod 12 (Fig. 1) corresponding pin 60, which is an opening 62 each of an operable with a grub screw 64 adjustment ring 66 is inserted. Each adjustment ring 66 is provided for insertion into a recess 38, 40 (see Fig. 5). This can be done by each setting ring 66 with a threaded portion 68, for example, a so-called. Rampa screw or the like, is integrally combined. An inner diameter of the recess 38, 40 is adapted to an outer diameter of at least the threaded portion 68, possibly of the threaded portion 68 and the adjusting ring 66, so that the adjusting ring 66 by the threaded portion 68 captive in the recess 38, 40 is fixed. Adjusting ring 66 and threaded portion 68 may also be in two parts, wherein the adjusting ring 66 is first introduced separately into the recess 38, 40 and is fixed there by later insertion, in particular screwing, the threaded portion 68 there. If a diameter of the pin 60, as shown, not insignificant deviates from the inner diameter of the threaded portion 68, it can be provided that the pin 60 has a matched to the inner diameter of the threaded portion 68 adjusting member 70, which centered insertion of the pin 60 first in the threaded portion 68 and later in the manufacture of the alternative wood connection 58 in the opening 62 of the adjusting ring 66 facilitates. For this purpose, the adjusting element 70, unlike that shown, can also extend over a longer section in the middle or at least substantially in the center of the pin 60. Each grub screw 64 can be actuated from the outer surface of the wood parts 30, 32 to be joined (see Fig. 5) in a direction perpendicular to the axial extent of the pin 60. Two wood parts 30, 32 to be connected to the alternative wood connection 58 are accordingly connectable to each other when in each wood part 30, 32 the adjustment ring 66 and the threaded part 68 are inserted into a corresponding recess 40, 42. At least one side of the pin 60 is then inserted into the respective threaded portion 68 and / or the adjusting ring 66. When combining the two wooden parts 30, 32 a hitherto free end of the pin 60 in the complementary threaded portion 68 and / or the adjusting ring 66 is inserted into other wooden parts 30, 32. An exact fit of end faces 34, 36 (see Fig. 5) is, if not the pin 60 is tuned in its length to the length of the juxtaposition of two threaded parts 68 and two adjusting rings 66, guaranteed even if the recess 38, 40 in the respective wooden part 30, 32 is at least slightly deeper than the longitudinal extension of the juxtaposition of threaded part 68 and adjusting ring 66 would require. The alternative wood connection 58 is particularly suitable when it comes to combining wooden parts 30, 32, in which a rotation of at least one wood part 30, 32 is not possible, for example in a combination of two counter-oriented handrail elements parallel to a respective Stair section through a U-shaped connecting element (not shown), which can be combined by two alternative connecting elements 58 on the end faces of such a connecting element with the respective handrail elements.

11 shows a view of the alternative connecting element 58 in a sectional representation. It can be seen in particular that the pin 60 is arranged concentrically to the threaded portion 68. The inner diameter of the opening 62 in the adjustment ring 66 is matched to the outer diameter of the pin 60, such that the pin 60 is insertable into the opening 62. All illustrated and / or described wood joints / wood fasteners are based on the principle that for receiving the wood joints or individual elements thereof a recess 38, 40 or the like in the respective wood part 30, 32 is introduced. For the centered introduction of such recesses 38, 40 are provided by the applicant adjusting devices, in particular in the form of a drilling jig.

Finally, it should be noted that the wood connection 10, even if it is consistently described as a wood connection, can also be provided for the connection of parts made of material other than wood. The invention also includes a connecting element according to the principle of the above-described wood connection. Finally, the parts 30, 32 made of wood or of other material need not necessarily be handrail segments. The (wood) compound according to the invention also comes to the combination of e.g. Furniture elements and the like into consideration.

Thus, the invention can be represented briefly as follows: A (wood) connection 10 is provided with a first and a second abutment 16, 18 and a clamping means combined or combinable with both abutments 16, 18, in particular in the form of a threaded rod 12 in which the tensioning means at least on one side a closing element 14 and between end element 14 and respective abutment 16, 18 arranged or arranged compressible spacer element 22 is assigned, wherein the spacer element 22, when the compound 10 is fixed in their use, allows further actuation of the clamping means , so that in the case of two (wood) parts 30, 32 to be joined together, any orientation of these parts 30, 32 relative to one another is achievable.
