Abstract

The invention relates to a device for vertical positioning of a mast or objects (4) similar to a post on a fixing device (6) placed at the end of the floor. The device comprises an elongated, substantially cylindrical mounting mandrel (10), which can be inserted into an intake bore (12) in the lower side of the post-like mast or object (4). The device further comprises a support plate (16) from which plane the mounting mandrel (10) extends upwards and on which the lower side (14) of the mast or pole-like object (4) rests. At least one fixing projection (18) protrudes upwardly from the support plate (16) and penetrates the mast material or object (4) similar to a pole. The mounting mandrel (10) is substantially thinner than the intake bore (12) on the underside of the post-like mast or object (4) so that there is considerable clearance between the mounting mandrel (10) and the perforation (12) that surrounds the mandrel on the underside of the mast or post. Due to this set, the mast or post (4) can be mounted on the mounting mandrel (10) so that the mast or post is tilted or tilted within a given angular range. This inclined or tilted position allows the compensation of any of the positions of the fixing device (6) placed at the end of the floor which are unbalanced in relation to the vertical

Description

DEVICE FOR THE VERTICAL PLACEMENT OF A MAST OR SIMILAR OBJECT TO A POST DESCRIPTION OF THE INVENTION The invention relates to a device for the vertical positioning of a mast or pole-like object on a fixing device placed at the end of the floor, according to the preamble of claim 1. When erected masts or poles, for example When a fence is erected, when a sign is placed on a road or similar, the problem always arises of keeping the mast or pole in an exactly vertical position, if possible. The vertical positioning of a mast or pole can be carried out, for example, by checking and possibly correcting the vertical positioning by means of a water level or a plumb line when the mast or pole is fixed or anchored on the ground when propelled. or when embedding it in the cote. This is problematic and time consuming, because when a mast or post is driven therein, for example, the driving operation must be repeatedly interrupted in order to verify and possibly correct the placement of the mast or post. When a cote mast or pole is embedded, the exact vertical placement of the same can be corrected without REF: 26877 difficulties before the cote has hardened, however, the means that must be applied to maintain this position exactly vertical until the cote has hardened so that this vertical position does not change more by itself; that is, the mast or pole must be held laterally or fastened, for example. In addition to driving or burying a pole or pole or in addition embedding it in cote, it is known to use fastening devices which can be anchored to the floor and which then hold the mast or similar object to a pole on its upper free end. The fixing device adapted to be anchored in the floor comprises, for example, a propeller or screw which is drilled in the floor similar to a corkscrew, where the mast or pole is then screwed to this fixing device or inserted in the same. It is additionally known to form integrally the mast or pole-like object and the fixing device to be anchored on the floor similar to a corkscrew so that the mast or pole-like object includes at one of its free ends the fixing device which is then screwed on the floor and fixed on it. With this method or these possibilities of erecting a mast or pole as well, substantially the same problems arise with respect to the vertical positioning of the mast or pole that arise when the latter is driven or embedded in the cote. Instead of the driving operation, the screwing of the fixing device on the floor must be interrupted repeatedly in order to ensure the final vertical position of the mast or post by appropriate measurement and possibly correction stages. From DE-GM 89 03 236, a fastening device for wooden beams or the like is known, especially wooden designs of vertical playground frames This known device comprises a fixing device placed at the end of the floor in the form of a fixing member to be anchored in the floor or foundation or a support member placed thereon and adapted to be positively coupled with the mast or pole. The support member is a vertically extending trunnion which is retained in a recess in the underside of the post, so that the post fits snugly around the trunnion, i.e. in a virtually positive fixation manner. In addition, a support surface or support plate for the post is provided from which plane the die extends upward and on which the lower side of the post rests. The support plate further has a ring which penetrates the front by applying blows on the upper end of the pole and provides a fixation of the position in the transverse direction. As an additional protection against removal or detachment, a transversely extending bolt is provided which passes horizontally both through the material of the post and through the stump material. By means of the pole shoe, according to DE-GM 89 03 236, the pole or mast is held at a particular distance above the floor so that it is better protected against the influence of the environment due to rain, snow or similar as well as against insects and weeds. Although by the purpose of the mast shoe according to DE-GM 89 03 236, the objective provided here can be obtained and substantial problems with respect to the loss of the fixing device are not expected, because the mast is slid on the stump substantially without force -except for the application of a blow on the upper end-, this pole shoe of this fixing device has the essential disadvantage, however, due to the narrow positive fixing that surrounds the stump by the material of the mast or post, the mast shoe itself must be set exactly vertical on the floor in a manner that ensures a vertical position of the mast or pole supported by it. The generic document DE-GM 93 13 260 suggests an adjustment device provided between the fixing device adapted to be anchored in the floor, for example a floor screw, and the mast or pole-like object to be fixed to the floor. same. In accordance with a form of DE-GM 93 13 260, this adjustment device substantially comprises a cylindrical elongate mounting mandrel projecting upwards from the free upper side of the fixation device and which is adapted to be inserted in the perforation of Admission on the underside of the mast or similar object to pole. The axial extension of the mounting mandrel and the depth of the intake bore are selected so that the first is somewhat greater in its depth with respect to the latter so that when there is a slip, the mast or pole-like object on the Mounting chuck, the free end of the latter rests on the bottom of the intake bore. The mast or pole-like object is now held in an exactly vertical position - possibly with the help of a plumb line or a water level - and then one or more strokes are applied to the upper end of the object so that the free end of the object Mounting mandrel penetrates the bottom of the blind hole and therefore the object is fixed in its exactly vertical position face to face with the fixation device.

The subject matter of DE-GM 93 13 260 has been widely tested successfully in practice; however, again it has the minor defect that - as in the case of DE-GM 89 03 236 - due to the narrow positive fixing that surrounds the stump by the material of the mast or pole, the mast shoe itself it must be fixed exactly vertical on the floor in such a way as to ensure a vertical position of the mast or post that is maintained by it. Like the rest, in addition to the mast shoe in accordance with DE-GM 89 03 236 can cause problems with a loosening of the fastening device placed on the side of the floor, if the material of the mast or pole is especially hard so that a particular energy expenditure is required to drive the ring with teeth into the front of the mast or pole. Although DE-GM 93 13 260 in additional configurations suggests adjustment devices between the post and the fixing device that are capable of holding the post in an exactly vertical position, even if the fixing device is mounted on the floor obliquely or Outside of the perpendicular, these adjustment devices are rather complicated and therefore are expensive, however. In comparison with this, it is an object of the present invention to provide a device for vertical positioning of a mast or pole-like object in a fixing device placed at the end of the floor, in which, after the fixing device placed at the end of the floor it has been anchored, the exact vertical position of the mast or pole-like object is to be fixed to it and can be subsequently adjusted permanently, where the placement of the fixing device on the floor can not be changed or loosened during this adjustment operation. This object is obtained, according to the invention, by the features described in claim 1. In accordance with the invention, a possibility of vertical positioning or adjustment is provided in a surprisingly simple manner by the fact that the mounting mandrel is substantially thinner than the housing perforation on the underside of the mast or pole-like object so that a play or clearance that is substantially observed is provided between the outer periphery of the mounting mandrel and the inner circumferential area of the intake bore. over the entire axial extension of the mounting mandrel. In other words, in contrast to the teaching of DE-GM 89 03 236 or DE-GM 93 13 260 in which the material of the mast or post is fixed around the mandrel or core in a positive fixing manner, there is considerable play against the mounting mandrel or mandrel and the bore that surrounds the mandrel on the underside of the mast or post, between the outer periphery of the mounting mandrel and the inner circumferential area of the intake bore that is substantially observed over the entire axial extension of the mounting mandrel. Due to this set, the mast or post can be mounted on the mounting mandrel so that the mast or post tilts or tilts within a given angular range, this tilted or tilted position allows for compensation of any position of the fixation device placed at the end of the floor which is unbalanced in relation to the vertical. Advantageous further developments of the invention constitute the subject matter of the dependent claims. Preferably, a plurality of fixing projections extend upwards from the support plate on which the underside of the mast or pole-like object is supported, this can be known per se from DE-GM 89 03 236. Therefore, fixing of the mast or pole-like object in any relative position with respect to the device according to the invention is improved.

As an alternative to this, the fixing projection extends upwardly from the support plate and may be in the form of a closed circumferential ring. Therefore, the same advantages can be obtained as with the configuration in which a plurality of individual fixing projections are provided. At least one fixing projection is preferably bevelled in a knife-like manner on its free upper side. In this way, at least one fixing projection can penetrate the mast material or pole-like object. If the blade-like beveling extends towards the longitudinal axis of the device according to the invention, the risk of discharge or tearing of the mast material or pole-like object when at least one fixing projection penetrates is minimized. In a preferred embodiment in which the mounting mandrel has a tubular shape and is beveled similar to a blade, likewise, at its upper circumferential edge. Therefore, not only at least one fixing projection penetrates the material of the mast or object similar to the post but also the mounting mandrel penetrates the material of the object in the front wall of the intake bore.

The mounting mandrel may have at its upper end portion a through hole extending substantially horizontally through which passes a bolt having a dimension smaller than specified. The bolt extends to fit exactly in a transverse bore which is formed in the mast or pole-like object in true alignment with the through bore in the mounting mandrel. This measure constitutes a protection against removal or detachment so that the mast or pole-like object can not be easily removed from the device according to the invention by traction forces directed vertically upwards. Furthermore, this possibility of securing provides the advantage that even high poles can be securely fastened to which no blows can be applied to the upper ends or can be applied with difficulties due to their vertical extension. In addition, in the case of masts or poles for which hitting or driving tools can / should be used due to particular requirements (for example, to prevent the upper end from being splintered or nicked by a striking tool), this possibility of Fixation is especially advantageous. To the extent that the bolt passing through the through hole in the mounting mandrel has a dimension smaller than specified, this bolt does not prevent the possibly necessary tilting movements of the mast or pole-like object for vertical positioning of the same. Preferably, the bolt is a set screw which is screwed into the transverse bore in the mast or pole-like object. Therefore, the bolt can only be loosened by an appropriate tool so that a secure connection is guaranteed. Preferably, the support plate can be adjusted vertically along the mounting mandrel. This has the advantage that in the first place, the relative length of the mounting mandrel can be accurately adapted to the intake bore introduced in the mast or pole-like object. Furthermore, by virtue of the foregoing, the mast or pole-like object may be propped up on the device according to the invention - particularly in relation to the modality that includes the horizontally extending bolt. According to a preferred embodiment, the support plate is adjusted vertically so that the support plate rests on a base plate which, in turn, is in threaded engagement with the outer periphery of the mounting mandrel. By rotation of the base plate in the threaded part of the mounting mandrel, the base plate also moves vertically upwards or downwards and consequently drags the support plate. According to another preferred embodiment, the mounting mandrel can be constituted by two coaxial tubular sections, the outer tubular section can move vertically with respect to the inner tubular section and, in the case of vertical upward movement of the tubular section outside, it extends horizontally or radially in its upper end portion. This allows the mounting mandrel to penetrate into the intake bore of the mast or pole-like object so as to ensure protection against removal or detachment. Preferably, the outer tubular section has at its upper end portion a plurality of deformable tabs which, in the case of an upward vertical displacement of the outer tubular section, stop the fixed counter-profiles of the inner tubular section and curve by them horizontally / radially. This represents another preferred embodiment of the present invention, because by this reliable protection against removal or detachment is assured by simple construction means. further, according to a configuration of the invention, the support plate can be integrally designed with the fixing device. This configuration has an especially simple structure and handling as there are no moving parts. According to another configuration, if the support plate is a separate component of the fixing device which can be fastened to the lower front part of the mast or pole-like object and which makes a connection by friction and / or positive with At least one partial area of the outer periphery of the mounting mandrel, when inserting the mounting mandrel into the intake hole in the underside of the mast or pole-like object, one or more strong blows should not be applied to the upper end of the mast. mast or pole-like object for fixing the lower side or the front side of the mast or pole-like object on the support plate and on at least one projection of fixing thereof, respectively in order to further drive, in addition to driving the upper end of the mounting mandrel in the lower part of the intake bore, and at least one fixing projection in the front part of the stil pole or similar object. Therefore, the stress and forces acting on the fixing device placed at the end of the floor when the mast or pole-like object is fixed is substantially reduced and therefore, the damage possible is similarly reduced. or loosening. Therefore, a possibility of placing or vertically adjusting the mast or pole-like object in a simple manner is provided and the risk of the anchoring device placed on the floor loosening when this object is fixed is avoided. In the aforementioned embodiment, the support plate preferably comprises a central opening, the circumferential edge of which is in contact by friction and / or positive fixing with at least a partial area of the outer periphery of the mandrel of mounting. This is a form of the support plate which is easy to manufacture and which can be handled in practice with minimal effort to fix it to the mounting mandrel. The opening may have a polygonal or round cross section, based on the cross section of the mounting mandrel and possibly to the existing requirements. However, in practice, a round cross section is likely to be particularly advantageous considering the costs and manufacturing efforts for the mounting mandrel and the intake bore in the underside of the pole-like object mast and for the manufacture of the opening in the support plate itself.

The inner diameter of the opening is, at most, equal, but preferably smaller than the outer diameter of the mounting mandrel. According to another preferred embodiment, in accordance with the above and especially when the opening in the support plate is surrounded by a plurality of flexible tabs, the opening of the support plate is automatically anchored to the mounting mandrel. This fixing effect can be intensified and therefore further improved by the fact that at least one partial area of the outer periphery of the mounting mandrel has a knurling or knot. Especially in combination with the preferred embodiment that the opening in the support plate is surrounded by a plurality of flexible tabs, whereby the inner diameter of the opening is smaller than the outer diameter of the mounting mandrel, a fixing is obtained reliable of the position and especially a protection against the distortion of the mast or object similar to attached pole based on the fact that the points of the retention tabs penetrate the knurls provided in the mounting mandrel. The additional details, aspects and advantages of the present invention are those resulting from the following description of various embodiments by means of the figures, in which: Figure 1 is an exploded view of one embodiment of the present invention in the disassembled state;; Figure 2 is a view corresponding to Figure 1 in the assembled state; Figure 3 is a top view of one embodiment of the support plate; Figure 4 is a view corresponding to Figure 3 of another embodiment of a support plate; Figure 5A and 5B show another embodiment of the present invention; Figures 6A and 6B show another embodiment of the present invention; Figure 7 shows another embodiment of the present invention; and Figure 8 shows another embodiment of the present invention. The following description of the preferred embodiments of the present invention should be considered as illustrative and exemplary only; the representation of the figures and the corresponding description should not be understood as restrictive. Figure 1 shows a first embodiment of the present invention for the vertical positioning of a mast or pole-like object (hereinafter referred to as "mast") in a fixing device placed at the end of the floor. Figures 1 and 2 represent an embodiment of a device 2 according to the invention which serves for the vertical positioning of a mast 4 in a fixing device 6 adapted to anchor on the floor, for example. The fastening device 6 can be buried in the floor or embedded in concrete or it can be screwed into the floor preferably in a manner similar to a corkscrew. A particularly preferred embodiment of the fixation device 6 is described in DE-GM 93 13 258 of the same applicant. The content of the description of that document is completely referenced herein. In the embodiment of the device 2 illustrated in FIGS. 1 and 2, the device comprises at the upper free end of the fixing device 6 a stepped portion or step 8 centrally supporting a tubular mounting mandrel 10. As can best be seen from Figure 2 - the outer diameter of the mounting mandrel 10 is definitely smaller than the inside diameter of an inlet or blind bore 12 formed in the lower free end of the mast 4. Preferably, the depth of the perforation 12 is smaller than the height of the mounting mandrel 10 in this case.

A support plate 16 can be placed between the rung 8 and the front part 14 of the mast 4 where the perforation 12 is inserted. The support plate adapts in form and surface to the shape and surface of the front part 14, that is, it is usually circular as shown in figures 3 and 4. At least one, and preferably several fixing projections 18 extend upwards from the upper side of the support plate 16 in the direction of the front 14. In this case, according to the drawing, a plurality may be extended upwards. of fixing projections 18 in the form of protruding parts, tips or coarse nails from the support plate 16, or in addition the fixing projection 18 has the shape of a closed circumferential ring surrounding the periphery of the support plate 16. The fixing projections 18 are preferably bevelled in a similar manner to blades at their upper free ends, the bevelling extending towards the central longitudinal axis of the device 2. In the same way, the upper free edge of the mounting mandrel 10 is beveled similar to a blade. If the knife-like bevels extend towards the longitudinal axis of the device 2 according to the invention, the risk of an open discharge or fracture of the material of the mast 4 while penetrating the projections is minimized. The attachment of the mast 4 to the device 2 is carried out in such a way that a fixing device 6 is anchored in the floor, for example by screwing it in or by incrustating it in particular. After the support plate 16 is placed on the lower side or the front part 14 of the mast 4 and connected with the front part 14. For this purpose, the fixing projections 18, which penetrate into the mast material 4 , when one or more hammer blows are applied to the support plate 16, they are provided in the support plate 16. As an alternative to the embodiment of the fixing projections 18 shown in FIGS. 1 and 2 in the form of a protruding part or of points similar to tips penetrating the material of the mast 4, the fixing projection 18 can have the form - as mentioned above - of a closed circumferential ring surrounding the periphery of the support plate 16. As another alternative, according to Figure 3, a plurality of perforations 20, which allow the adhesion nails or clips or the like to penetrate the material of the support plate 16 with the help of such fixing means in the front part of the mast 4 can be provided on the support plate 16 so that the support plate 16 can be clamped. In any case, the support plate 16 has a central opening 22 which is formed in the support plate 16 so as to be substantially in alignment with the perforation 12 in the lower end portion of the mast 4 after the plate 16 of support has been attached to the front 14. After joining the support plate 16, the mast 4 according to figure 1 is mounted on the fixing device 6 from the top, the mounting mandrel 10 is inserted into the perforation 12 through the opening 22 by a predetermined force. In this case, the mast 4 is based on the upper edge of the mounting mandrel 10 with a base 24 of the bore 12. According to FIG. 2, then the mast 4 is tilted - preferably with the help of a plumb bob or a water level - so that the possible inclinations of the fixing device 6 are compensated and the mast 4 is placed exactly vertical. The mast 4 is capable of tilting with respect to the fastening device 6 in that the outer diameter of the mounting mandrel 10 is definitely smaller, according to the invention, in comparison with the internal diameter of the perforation 12 in a manner that the mandrel 10 can extend obliquely or out of the perpendicular within the perforation 12, as illustrated in figure 2. As soon as the mast 4 is placed exactly vertical, one or more blows are applied to the upper free end of the mast 4 by a hammer or other suitable driving tool so that the upper circumferential edge of the mounting mandrel 10 penetrates the base 24 of the bore and therefore, according to Figure 2, the mast 4 is maintained with respect to the security device 6. In addition, by interposing the support plate 16 to the mounting mandrel 10, the mast 4 is kept close to the rung 8, where the support plate 16 bears fully or partially - based on the degree of inclination of the mast 4 - on the Rung 8. The support plate 16 mounted on the mounting mandrel 10 in which the inside diameter of the opening 22 is at most, or preferably less than, the outer diameter of the mounting mandrel 10. Therefore, a frictional and / or positive fixing contact or a connection of the support plate 16 with at least a partial area of the outer periphery of the mounting mandrel 10 is carried out so that the position of the mast 4 is fixed immovably with respect to the fixing device 6. This connection by friction and / or positive fixing of the support plate 16 and the opening 22 with the mounting mandrel 10 can be intensified by the fact that at least a partial area of the outer periphery of the mandrel 10 is provided. assembly with a knurling 26. According to figure 3, the opening 22 in the support plate 16 can also be surrounded by a plurality of flexible tabs 28 which deform elastically (ie, curve upwards) when the mast 4 it slides on the mounting mandrel 10, in which the mounting mandrel 10 penetrates the opening 22, so that especially in relation to the knurling 26, the support plate 16 and therefore the mast 4 are fixed in a manner secure with respect to the fixing device 6. Due to the flexibility of the tabs 28, the mast 4 can be tilted within a wide range with respect to the mounting mandrel 10 and therefore of the fastening device 6. By the knife-like beveling of the upper circumferential edge of the mounting mandrel 10, this portion can easily penetrate the material of the mast 4. Additionally, the knife-like beveling is carried out continuously towards the central longitudinal axis of the device. 2, no outwardly directed or discharge forces are exerted on the material of the mast 4 so that the entire lower portion of the mast 4 - with the exception of the penetrating projections 18 - remains undamaged and therefore atmospheric influences, insects, weeds or the like are less susceptible. The cross section of the opening 22 substantially depends on the cross section of the mounting mandrel 10. That is, when the mounting mandrel 10 is tubular and has a circular cross section, the opening 22 also has a preferably rounded cross section, as shown in Figure 3, where the flexible tabs 28 are still possibly provided. In the same way that the opening 22 can have a square cross-sectional shape (Figure 4: solid lines) or a polygon (Figure 4: dashed lines). A polygon cross section of the opening 22 with a rounded cross section of the mounting mandrel 10 can also be used. Even in the case of a square or polygon cross section of the opening 22, flexible retention tabs can be provided. Since the support plate 16 is fixed to the front part 14 of the mast 4 before the mast 4 slides on the mounting mandrel 10 of the fixing device 6, the forces required to fix the mast 4 in the device 6 of Fixation is limited to those forces which are necessary for sliding of the mast 4 in the mounting mandrel 10, the latter passing through the opening which preferably has a dimension smaller than that specified, and the forces required to press or driving the mandrel 10 in the base 24. So that the risk that the fixing device 6 can loosen in the floor by forces applied to the mast 4 to secure it is substantially reduced. Figures 5A to 8 show additional embodiments of the present invention for the vertical positioning of a mast or pole-like object in a fixing device placed at the end of the floor. In figures 5A to 8, the like reference numbers indicate equal or corresponding parts with respect to figures 1 to 3; these parts are not explained again. In the configuration of the device 2 shown in FIGS. 5A and 5B, this device includes at its upper free end of the fixing device 6 the stepped area on the rung 8, which, in turn, supports the tubular mounting mandrel 10 centrally. . Here, the outer diameter of the mounting mandrel 10 is, in a defined or substantial manner - as can better be seen from Figure 5B - smaller than the inner diameter of the intake or blind bore 12. Again, the depth of the borehole 12 is, at most, equal to, but preferably smaller than, the height of the mounting mandrel 10. At least one fastening projection 18 extends upwardly, radially outwardly from the rung or support plate 8. Again, here, a plurality of fastening tips or projections 18 may be extended in the form of thick nails upwardly from the step 8 or in addition, the fastening projection 18 has the shape of a closed circumferential ring surrounding the rung 8. according to FIGS. 5A and 5B, as in the embodiment of FIGS. 1 to 3, the fixing projections 18 are beveled similar to blades at their upper free end, the bevelling extends towards the central longitudinal axis of the device 2. In the same way, the upper free edge of the mounting mandrel 10 is beveled in a knife-like manner. The mast 4 is fixed on the device 2 so that the first fixing device 6 is again fixed on the floor, for example by screwing it in or inlaying it in particular. After the mast 4 is assembled from the top of the fastening device 6, according to Fig. 5A, the mounting mandrel 10 is inserted into the bore 12. The mast 4 rests on its lower surface or front part 14 in the fixing projections 18 and the front part or base 24 of the perforation rests on the upper edge of the mounting mandrel 10. Then, according to FIG. 5B, the mast is tilted - preferably with the help of a plumb line or a water level - so that the possible inclinations of the fastening device 6 are compensated and the mast 4 has a vertical position Exact This tilting of the mast 4 with respect to the fixing device 6 is allowed by the fact that the outer diameter of the mounting mandrel 10 is substantially smaller than the inner diameter of the perforation 12 so that the mandrel 10 can extend obliquely or outwardly. of the perpendicular within the perforation 12, as shown in Figure 5B. As soon as the mast 4 is positioned exactly vertical, one or more strong blows are applied to the free upper end of the mast 4 by a hammer or other suitable driving tool so that the fixing projections 18 penetrate into the lower area 14 of the mast 4. mast 4 and, in addition, the upper circumferential edge of the mounting mandrel 10 penetrates the front part 24 of the bore 12 so that, according to Fig. 5B, the mast 4 is retained with respect to the fixing device 6. In addition, the mast 4 is supported with part of its lower surface 16 on the rung 8 which in this way corresponds in its function together with the fixing projections 18 to the support plate 16 of figures 1 to 3. The mode of according to FIGS. 5A and 5B, it is sufficient, provided that during the subsequent use no upwardly directed tensile forces are applied, that is to say, for example in the case of support beams or joists which absorb pure pressure forces. However, such upward tensile forces must be expected, preferably when one of the embodiments according to Figures 1 to 3 or 6A to 8 is used. In Figures 6A to 8, again the like reference numbers indicate equal parts or corresponding to those of Figures 5A and 5B. According to figure 6A, the device 2 there again comprises the mounting mandrel 10, which is preferably formed integrally with the fixing device. The mounting mandrel 10 includes a through bore 30 extending substantially horizontally at its upper free end. In the fastening device 6, a male thread 32 is formed which engages with the female thread provided in the base plate 34 immediately adjacent to the mounting mandrel 10. The support plate 16, which can move freely along the male thread 32, ie, is not coupled with the male thread 32, bears on the upper side of the base plate 34. The fixing projections 18 extend upwards from the support plate 16 again. According to FIG. 6B, a horizontally extending bolt 36 is inserted in a bore 38 extending horizontally in the mast 4 passing through the through bore. The bolt 36 has a dimension considerably smaller than that specified, face to face of the through bore 30 so that, according to FIG. 6B, the bolt 36 and therefore the mast 4 can be tilted with respect to the device 6. of fixation, in which, due to the smaller dimension of the bolt 36, it can extend obliquely in the perforation 30 through. Preferably, the bolt 36 is inserted to fit exactly in the bore 38 of the mast 4, in a particularly preferred embodiment it is screwed in such a way that the bolt 36 is securely retained in the mast 4. To fasten the mast 4 in the fixing device 6, first, the mast 4 slides from the top on the mounting mandrel 10 and is subsequently fixed by means of the bolt 36 in the bore 30. Therefore, the bolt 36 prevents the mast 4 Remove or detach towards the top. After the base plate 34 is rotated so that, in FIGS. 6A and 6B, it moves upwardly along the male thread 38 and thus drags the support plate 16. While the base plate 34 is therefore screwed up to the supporting plate 16, the fixing projections 18 penetrate into the lower face 14 of the mast 4. According to FIG. 6B, the mast 4 can possibly be tilted with respect to to the fixing device 6 before the base plate 34 is bolted upwards in order to be able to compensate for possible inclinations of the fixing device 6. The mast 4 is braced on the fixing device 6 at any desired position by the base plate 34 and therefore by the support plate 16 on the one hand and, on the other hand, by the operating connection which functions as a protection against the removal or detachment between the bolt 36 and the perforation 30 through. Figure 7 shows a modified embodiment of that shown in Figures 6A and 6b. According to FIG. 7, a bolt 42 extends upwardly from the support plate 16 in the material of the mast 4 in which a washer 40 is interposed. The threaded portion of the bolt 42 meshes with the female thread 44 formed on a bolt 46 which extends substantially horizontally in a bore 48. According to FIG. 7, the bolt 46 has a dimension smaller than that specified, face to face with respect to the bore 48. A hex head of the bolt. 42 is accessible by means of a recess 52 in the fixing device 6, the recess 52 extends over a certain amount of the periphery, for example 90 °. The bolt 42 is rotated by an open end wrench or a similar tool which is attached to the head 50 of the bolt by means of the recess 52. As can be directly considered from Figure 7, when the bolt 42 is tightened , the threaded portion of the bolt 42 moves upward relative to the bolt 46 and this upward movement of the bolt becomes in a downward movement of the mast 4 in Figure 7 due to the arrangement of the bolt 46 in the bore 48 so that the fixing projections 18 penetrate the lower face of the mast 4 and the tubular mounting mandrel 10 penetrates the face 24 front of the perforation 12 in the mast 4 so that the mast 4 is fixed with respect to the fixing device 6. Figure 8 shows a further embodiment of the present invention. The embodiment according to FIG. 8 is distinguished in particular by the fact that the mounting mandrel 10 consists of two coaxial tubular sections., specifically an outer tubular section 54 and an inner tubular section 56. The outer tubular section 54 is preferably formed in its lower end portion integrally with the support plate 16 which includes the fixing projection 18 projecting upward therefrom. As in the embodiment according to Figures 6A and 6B, the support plate 16 rests on the base plate 34 which is coupled with an external threaded portion in the mounting mandrel 10 and the inner tubular section 56, respectively. In the upper free end portion, the inner tubular section 56 expands to acquire a funnel shape in a visible manner from FIG. 8, and the outer tubular section 54 has a plurality of tongues 58. The tongues 58 are formed from Thus, the material of the outer tubular section 54 is provided with a plurality of recesses 60 in the upper free end portion. The conical or funnel-shaped expansion of the inner tubular section 56 forms a conical or funnel-shaped counterpart 62 corresponding to which the tongues 58 are adjacent. To fix a mast not shown in figure 8 on the device 2 according to With the invention, according to FIG. 8, the mast is tilted on the mounting mandrel 10 so that the lower side of the mast rests on the knife-like beveling of the fixing projections 18. Then, the base plate 34 is rotated - possibly by a suitable tool - upwardly on the inner tubular section 56 along the external threaded portion, whereby the support plate 16 in Figure 8 moves the same upwards. This upward movement of the support plate 16 is transmitted by means of the outer tubular section 54 to the tabs 58, so that the tabs 58 are folded substantially horizontally or radially outwardly by the conical counterpart 62 and penetrate the material of the mast inside the perforation 12. At the same time, the fixing projections 18 penetrate into the underside of the mast so that the mast is supported securely. Although not shown in Figure 8, it is understood that in this embodiment as well, the perforation in the mast is interfering face to face with the mounting mandrel 10 so that the vertical positioning can be corrected, if necessary, before to finally tighten or hold the mast. It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates. Having described the invention as above, property is claimed as contained in the following:
