Definitions
- the invention relates to a device for the positive connection of a first component to a second component, wherein the two components do not have the function of nodes and bars in a bar structure, with matched engagement members on both components.
- WO 2009/062618 A2 proposes a bar structure in which the bars and nodes are interconnected in a manner that allows the bars to be inserted between the nodes without having to move the bar longitudinally relative to the nodes. Consequently, when inserting the bars, it is not necessary to temporarily increase the distance between the nodes.
- the connecting devices used in this case are particularly suitable for the connection of components made of wood or wood-like materials such. bamboo.
- the object of the invention is to generalize the type of compound proposed in WO 2009/062618 A2 to other applications.
- the invention is suitable, for example, for fastening table legs to tables or generally for fastening furniture feet to furniture.
- Another application example is the construction of towers or masts, such as masts of wind turbines, in which the mast is broken down into shorter segments for transport purposes, which are then connected to each other with the aid of the connecting devices according to the invention.
- the invention is suitable for the construction of pipes of various kinds, wherein the properties of the connecting device allow to replace individual tubes in the pipeline without the adjacent tubes must be changed in their position.
- the inventive Connecting device may also be advantageous for connecting parts of a machine assembly.
- 1 is a perspective detail view of engagement members on two components.
- FIG. 4 is a perspective view of a rod-shaped component
- FIG. 5 shows a section through an engagement region of a connecting device according to Fig. 4.
- FIG. 10 is a perspective view of a device according to another embodiment
- Fig. 15 is a section through a connecting device for tubes
- FIG. 16 shows a cross section of parts of a connecting device according to a further embodiment
- Fig. 17 a mast a wind turbine with an inventive
- FIG. 18 shows a gear transmission in which two gear wheels are held together by a connecting device according to the invention.
- a connection between a rod-shaped first component, hereinafter referred to as rod 20 and an arbitrarily shaped second component 14 will be described.
- the component 14 is part of a table top, while the bar 20 is a table leg.
- Fig. 1 is a perspective view of the cuboidal component 14 in this case, which is composed of two parts 24, 26.
- the part 24 is indicated only by dash-dotted lines and is not firmly connected to the table top, so that it can be moved relative to this or attached nightly.
- a cut end of a half-rod 32 is shown in solid lines, while a complementary half-bar 30 is indicated only by dash-dotted lines.
- An engagement member 34 of each half-rod has in this example the shape of a semi-cylindrical, hollow and open at the free end extension of the respective half-rod.
- the semi-cylindrical extensions of both half-rods 30 and 32 therefore complement one another to form a hollow voilocylinder.
- complementary engagement members 36 in the parts 24, 26 of the component 14 have the form of semi-cylindrical grooves, which complement each other after assembly of the parts to an annular groove.
- the engagement members 34 and 36 are shown in Fig. 1 respectively in the angular position, which corresponds to their engagement position, but these engagement members are shown axially offset, so that the structures are clearly visible.
- Fig. 2 and 3 it is shown how the connection between the half-bar 32 and the part 26 is made.
- the half-bar is first held so that a surface corresponding to the dividing plane 28 between the half-bars 30, 32 faces the surface of the part 26 which corresponds to the dividing plane 22 between the parts 24, 26, and that the engaging members 34 and 36 aligned with each other (Fig. 2).
- the half-rod 32 is rotated in the direction of the arrow A about the longitudinal center axis of the later complete rod 20, so that the engagement member 34 enters the groove-shaped engagement member 36.
- the half-rod is rotated by a rotation angle of 180 °, so that the engaging member 34 is completely received in the engaging member 36 and the dividing planes 22 and 28 are flush with each other.
- This state is not shown in FIGS. 2 and 3. Accordingly, one then proceeds to the other half-bar 30 and the associated part 24. Subsequently, the parts of the component 14 and the rod 20 are assembled and optionally glued together, and finally the then completed rod 20 is rotated back by 90 °, so that the half-rod 32nd assumes the position shown in Fig. 3. In this state, the engagement members 34, 36 are still engaged with each other, but no longer on an arc of 180 °, but only on an arc of 90 °.
- the engagement member 34 of the half-rod 32 is also engaged with the groove-shaped engaging member of the part 24 not shown in FIG. 3.
- the semi-cylindrical engagement members 34 then complement each other to a hollow solid cylinder which encloses a cylindrical pin which is bounded by the groove-shaped engaging members 36 and each half formed by the part 24 and the part 26.
- the two parts 24, 26 are now held together in a form-fitting manner in the direction transverse to the longitudinal direction of the rod 20, without it still being important for the bonding between them.
- the two half bars 30 and 32 are held together by the engagement members 36 positively.
- the inner and outer surfaces of the engagement members 34 may also be glued, thereby fixing the rod 20 in its angular position after the adhesive has cured.
- the positive locking of the parts together is then permanently retained, and the strength, in particular the tensile strength, of the connection depends on the thickness (thickness and length) of the engagement members 34, but not on the adhesive force with which the various parts are glued together. Since the connection is not formed by a plug connection, the extent of the overlap between the engagement members 34 and 36, so here the length of the semi-cylindrical structures, so large that the required strength is achieved without the table top must be raised. An extension of this overlap also increases the adhesive surface and thus in particular the tensile strength.
- the rod does not necessarily have to be divided at its longitudinal center plane into two half bars.
- Fig. 4 shows an example of a rod 20a, the middle part is formed as a round solid rod.
- This rod 20a may optionally be completed by parts that are complementary to the two end portions to form a solid rod the, which then can be used in the same manner as the rod 20 described above.
- a rod having the basic configuration shown in Fig. 4 can also be used alone, without additional complementary parts.
- the fully cylindrical middle section should then extend directly to the semi-cylindrical engagement members 34.
- Fig. 5 shows a section through the engagement member 34 of such a rod and through the parts 24, 26 in the engaged position. It can be seen that here too the only engagement member 34 of the rod engages in the engagement members 36 of both parts 24, 26 and holds them together in a form-fitting manner.
- Fig. 6 shows an embodiment similar to that of FIGS. 1 to 3, but in which the engagement members 34, 36 have mutually complementary dovetail profiles.
- the engagement members 34, 36 have mutually complementary dovetail profiles.
- the dovetail-shaped engagement members 34 and 36 also provide in the longitudinal direction of the rod 20 and the half-bar 32 a positive connection between the rod and the adjacent component ago.
- Fig. 7 shows in a similar representation as in Fig. 6, a variant in which the positive engagement is not achieved by dovetail profiles, but by a collar 38 and an annular groove 40 on the engagement members 34 a, 36.
- the engagement members 34 and 36 thread-like structures, which allow both a positive connection in the longitudinal direction of the rods as well as a tension of the components in this direction. Shown here are both parts 24, 26, each with a view of the dividing plane 22, and both half bars 30, 32, each with a view of the side facing away from the division plane 28 side.
- the engagement member 34 of the half-rod 32 has on its outer peripheral surface, which extends over an arc angle of 180 °, a thread-shaped bead 42, and the engagement member 36 of the part 26 of the component 14 has two thread-shaped Grooves 44, 46 which are both part of a thread 42 complementary to the thread.
- the engagement member 34 has a corresponding bead 48, but in an axial position other than the bead 42 is located, and the part 24 has on its engagement member 36 has a complementary groove 50th
- the engagement member 34 is brought into a position in which the upper end of the bead 42 in the drawing is aligned with the upper end of the groove 44 in the drawing. Subsequently, the half-rod 32 is rotated by 180 ° in a clockwise direction, so that the engagement member 34 screws into the engagement member 36. Accordingly, one proceeds with the half-bar 30 and the part 24th
- the dimensions c1 and c2 indicate the axial position of the leading end of the bead 48 and 42, respectively, with respect to the root of the engagement member 34, and the dimensions d1 and d2 fully represent the axial position of this leading end of the bead 48 and 42, respectively screwed state within the groove 46 and 50 at.
- FIG. 9 shows a variant embodiment in which the engagement members 34 and 36 respectively in the inner and outer half cylinder peripheral surface have a circumferentially extending groove 52 and 54 in corresponding positions. If the engagement members are screwed into each other, additional semi-annular wires or cords 56, 58 can be introduced, which then produce a positive connection in the axial direction.
- Figure 10 shows another embodiment of the component 14. This component is cubic and has in each of its six sides an engagement member 36 for a rod, so that the component z. B. a hub a rotary dryer or generally used to build a tree-like structure. In order that all the bars can be mounted in the manner described above, the component according to FIG.
- the sliding parts 26 ' can each be pulled away from the base part 24' at right angles to the said dividing line and inserted again in the opposite direction after insertion of the half rods into the base part 24 'and the sliding part 26'. to join the half bars into a solid stick.
- Figures 11 to 14 illustrate the establishment of a connection between a one-piece component 14 'and an at least two-part rod 20.
- the engagement member 36 is again formed by an annular groove, which is connected in this case, however, by a Einschleusungsnut 60 with a side surface of the component 14 ,
- the rod 20 is again formed by two complementary half rods 30, 32, but the engagement members 34 in this case are not semi-cylindrical, but formed as eccentrically arranged projecting pins.
- the profile of the half bars 30, 32 is indicated here only by dash-dotted lines, and serving as engagement members 34 pins are shown in section.
- the half-bar 30 is then rotated through 180 ° about the central axis of the annular engagement member 36 (and thus the central axis of the later solid rod) with its engagement member 34 moving through the annular groove, and the second half-rod 32 correspondingly via the Einschleusungsnut 60th introduced to complete the rod 20, as shown in Figure 13.
- the rod 20 is then rotated as a whole by 90 ° in the position shown in Figure 14, so that its engagement members 34, the in Take gur 14 shown position and hold together in cooperation with the engagement member 36, the two half-bars form fit.
- the half-bars can be glued together here as well, which prevents the half-bars from being able to be withdrawn again successively via the injection groove 60.
- a return stop 62 ( Figure 14) is arranged in the form of a resilient pawl at the confluence of Einschleusungsnut 60 in the form of a resilient pawl, which escapes upon insertion of the peg-shaped engaging member 34, but prevents a return of the pin in the Einschleusungsnut 60 ,
- the Einschleusungsnut 60 can be closed by a plug, or this Einschleusungsnut and / or serving as an engaging member 36 annular groove or parts thereof can be injected with a potting compound.
- FIGS. 12 to 14 can be generalized to connections in which the rods in the region of the engagement members are composed of three or more (sector-shaped) parts.
- Fig. 15 shows a device 70 for connecting two tubes 72, 74.
- the engagement members are here so arranged at the ends of the two tubes 72, 74, that the two tubes can be connected end to end with each other.
- both tubes 72, 74 are subdivided lengthwise into half-tubes, which correspond to the half-bars 30, 32.
- a division may be provided only at the tube ends, in the region of the engagement members.
- the engaging members of the tube 72 formed by grooves are formed in a sleeve-like thickening at the tube end.
- this is not mandatory.
- the engagement members can be fully integrated into the pipe wall of constant thickness.
- the connection shown in Fig. 15 is suitable, for example, to assemble masts for wind turbines and the like of relatively light and short segments.
- the construction of piping is possible.
- Fig. 16 illustrates a way, at the same time to clamp the components to be connected during rotation, by which the lock is made, more firmly together.
- the groove forming the engagement member 36 does not have a constant width, but its width varies periodically in the circumferential direction, in the example shown with a period of 90 °.
- the engagement member 34 is shaped complementarily thereto. Now, if the engagement member 34 is screwed into the groove, it is initially increasingly braced between the walls of the groove, since the width of the groove initially decreases. Only when a certain dead center is overcome, in the example shown at 45 °, the tension decreases again. In this way, inadvertent turning back into the release position is effectively prevented.
- the engagement members 34, 36 may also have a clinician wheel-like profiling, so that they can only rotate in one direction against each other, while a reverse rotation is prevented.
- the pawls also that the locking takes place in the locking position at an angular position in which the voltage between the engagement member 34 and the walls of the groove is maximum.
- a mast 76 of a wind turbine is shown.
- the mast consists of two segments 78, 80, which are completed at the ends facing each other by semi-circular, belonging to the connecting device inserts 82, 84.
- the heart of the connecting device is a ring 86 which is composed of two half rings and on the top and the bottom engaging members (not visible here) carries, which are analogous to the engagement members 34 in Fig. 1 and formed with grooves in the segments 78, 80 and the insert parts 82, 84 cooperate.
- one of the half rings is rotated with its engagement members into the grooves of the segments, and the other half ring is correspondingly connected to the inserts 82, 84.
- FIG. 18 shows, as a further example of application, a toothed gearing 88 with a drive gear 90 and an output gearing 92, which are mounted between two fixed housing parts 94.
- Another gear assembly 96 (machine assembly) consists of two gears 98, 100 which are non-rotatably mounted on a shaft 102. This shaft is also mounted in the housing parts 94. The gear 98 meshes with the drive gear 90 and the gear 100 meshes with the output gear 92.
- the gears 98, 100 are each divided along a diameter in two halves and interconnected by a device according to the invention. Engagement members 104 of the connecting device are indicated by dash-dotted lines. A transverse pin 106 rotatably supports the gear assembly 96 on the shaft 102.
- the cross pin is removed, and the two gears 98, 100 are rotated against each other until the engagement members 104 reach the unlocked position.
- the gears 98, 100 can then be disassembled and removed in their halves, without the distance between the housing parts 94 must be increased or the shaft 102 must be removed.
