Description

"UNION"

The present invention relates to a coupling means for connecting a first component to a second component, especially for connecting furniture or machine parts, comprising a first coupling element placed on the first component when the components are connected and a second coupling element. joint placed on the second component when the components are connected, with at least one of the joint elements having a curved, arcuate bearing surface to the longitudinal section.

Such joining means are known, for example, from AT 373 046 or DE 28 16 134 A1. According to AT 373 046, each of the joining elements has a hooked top protruding toward the other element. These two ends of the elements are laterally engaged to realize the union between the elements. According to DE 28 16 134 A1 each of the coupling elements has a hook which engages with the hook of the other coupling element from behind when the coupling elements are connected, the coupling elements for establishing the coupling being offset against each other parallel to the contact surfaces of the side-by-side components.

The coupling elements of AT 373 046 and DE 28 16 134 Al need to be fixed with additional screws or glue to ensure that they do not unintentionally loosen, or otherwise the coupling elements are secured in such a way that It is no longer possible to separate them.

DE 196 04 243 C2 discloses a component connection fitting consisting of two halves, each of which is fixed to one of the components to be connected and has engaging elements which cause component bonding; each of the trim halves has a circle segment-shaped section with self-cutting protruding edges, so that each of the trim halves, when inserted into the respective mating component, may be anchored to the respective component longitudinally to the self-cutting edges.

The union of the two components established with this trim can no longer be undone, or can only be undone with difficulty. In addition, the trim according to DE 196 04 243 C2 presents the risk of breakage of the sidewalls of the respective component due to the forces formed by the self-cutting protruding edges when the trim halves are inserted.

The task of the present invention is to create a connecting means of the type mentioned above which enables a secure and separable joining of two components without the risk of damage to the two components in their respective assembly.

This task is solved with the coupling means having the features of the general concept of Claim 1 according to the present invention, wherein the first coupling element and the second coupling element, when connected, are detachably joined by and at least one another. at least the first coupling member has a housing and at least one movable fastener relative to the housing of the first coupling member, which in the fixed position acts in conjunction with the second fastener to prevent relative movement of the first coupling member and second coupling member longitudinally to the direction of the coupling and, in the released position, acts to permit relative movement of the first coupling member and the second coupling member longitudinally to the connection direction ; at least one of the fasteners may be moved, externally to the coupling means, from the fixed position to the released position and / or from the released position to the fixed position; the housing of the first coupling member has a curved arcuate bearing surface to the longitudinal section and an essentially flat positioning surface opposite the bearing surface which can be applied to the second coupling member.

The solution according to the invention is based on the concept of establishing the union of the two connecting elements not by relative displacement of the two connecting elements as a whole, but rather by a movement relative position of the fastener with respect to a housing of the first coupling element from the released position to the fixed position. Alternatively, or in addition, the connection between the joining elements may be broken by moving the securing member relative to the housing of the first securing member from the fixed position to the released position.

Because at least one of the connecting elements has a curved, arch-shaped support surface to the longitudinal section, this support surface can slide over the equally curved and arc-shaped bottom surface of a longitudinal section. provided in one of the components, allowing the alignment of the respective connecting element to the other fixing element, subject to certain limits, to be altered when the elements are connected in order to compensate for position tolerances of the cavities in which the connecting elements connection are arranged and / or manufacturing tolerances of the connection elements.

When assembling the two components this additional degree of freedom of movement allows corrections to their positions, reducing the precision requirements regarding the position of the cavities in the components and providing considerable ease for the user.

If the connecting elements are interlocked by moving the fastener to the fixed position, the pulling forces acting on the connecting elements in a transverse, preferably vertical, direction of connection to the positioning surfaces of the connecting elements will activate so much friction that The degree of freedom of movement mentioned will be nullified by establishing a fully fixed connection between the components to be connected.

The connecting elements of the connecting means are inserted into their respective wells provided in the components so that there is no need to apply too much force to the insertion of the connecting elements into the components and therefore no damage to the components occurs.

On the contrary, to insert the DE 196 04 243 C2 trim halves into the components it is first necessary to form the fixing cavities of the trim components using the self-cutting protruding edges. This requires considerable use of force. In addition, the self-cutting protruding edges must be geometrically optimized for self-cutting effect and must be sufficiently thin to allow removal of the dug material. Furthermore, insertion of the trim halves into the components may cause material to break from the outer edges of the component, especially when the trim halves are inserted into the edge of the component. For sturdy materials such as hardwood, inserting the trim halves is extremely difficult. In other materials, such as acrylic and metallic materials, for example, the self-cutting insertion of the trim parts is totally impossible. In addition, after insertion, the trim halves are permanently fixed and immobile in the respective component and cannot be moved along the fixing cavity in order to correct the position and thus allow tolerance compensation.

When the fixing element of the connecting means has been moved from the fixed position to the released position, the connecting elements may be moved apart in a vertical connection direction to the positioning surfaces of the connecting elements, - which are in contact with each other. when the connecting elements are in a connected state - without the connecting elements having to be proximal to each other in a direction parallel to the positioning surfaces.

In the preferred embodiment of the invention the essentially flat positioning surface of the first connecting element may be applied to an equally flat positioning surface of the second connecting element. Preferably, in the connected state of the components to be

For example, it may be anticipated that at least one element of

This will prevent the additional dowels needed on most other connection means.

If at least one receiving recess has a longitudinal extension to the connecting means greater than the socket projection therein, we have the advantage that the first connecting element and the second connecting element can be longitudinally displaced. relative to each other, allowing compensation of tolerances in the connection between the components. For especially efficient anchoring at least

Equally or functionally equivalent elements are represented with the same reference symbols in all figures.

The first embodiment, represented in Figures 1 to 9, shows

below is shown with a connecting means represented as a whole by the number 100, showing by way of example the connection of a first essentially plate-shaped component (102) to a second substantially plate-like component (104) (see Figures 1 to 4).

The two components 102 and 104 are, for example, made of wood or plywood, but may also be of any other material, for example metallic or synthetic material (eg acrylic). Further, it may be provided that the first component 102 and the second component 104 are made of materials different from each other.

In the connected state of the two components 102 and 104, shown in Fig. 7, a contact surface 106 of the first component 102 forming a narrow side is in contact with the contact surface 108 of the second plate-shaped component 104 forming a main surface.

On each of the contact surfaces 106, 108 leads a cavity 110 formed in the respective components 102 and 104. This cavity includes a base section 112 in the form of a cylinder cap segment or cylinder cap section and two recess sections 114. extending in the direction of thickness 116 from the base section 112.

The radius of curvature of the base section 112 is greater than the depth T of the cavity (see Fig. 4), so that the bulging surface of the bottom of the cavity 118 cuts the respective contact surface 106, 108 at an acute angle. The base section 112 of cavity 110, in the direction of thickness 116, has a width B of approximately 8 mm, for example.

Each of the recess sections 114 of cavity 110, on respective side apart from respective contact surface 106, 108, abuts a bottom surface 20 flush with the bottom surface of cavity 118; surface 120 has a cylinder cap section shape and has the same radius of curvature as the bottom surface of cavity 118 of base section 112.

Toward the contact surface 106 and 108, each of the recess sections 114 is limited by a recess surface 122 of cylinder cap section disposed concentrically to the bottom surface 120 having a smaller radius of curvature.

Laterally each of the recess sections 114 is limited by a lateral limiting surface 124, vertical to the respective contact surface 106 or 108.

The width, i.e. the extension in the thickness direction 116, is approximately Imm for each indentation section.

The height, that is, the distance between the base surface 120 and the recess surface 122 is approximately 2 mm for each of the recess sections 114.

The base section 112 of each cavity 110 is bounded by limiting sidewalls 126 disposed essentially vertically to the respective contact surface 106 or 108. The sidewalls are spaced from the width B of the cavity.

As can be seen from Fig. 3, for example, an essentially cylindrical access hole 128, vertical to the boundary walls 126, flows into the cavity 110 of the first component 102; the other end of this bore flows into the main surface 129 of the first sheet member 102 to allow access from the outer space of the first member 102 to the base section 112 of cavity 110.

For forming the cavities 110 described above in components 102 and 104, for example, a milling equipment 130 as shown schematically in Figures 10 and 11 can be used.

This milling equipment 130 includes an electrically insulated housing 132 with an essentially flat lower bearing surface 134 and an anterior bearing surface 136, also substantially flat and vertical to surface 134.

The front surface 136 has a through slot 138 through which a section of a milling disc 140, which is rotatably suspended about an axis of rotation 142, may be passed into the inner space of housing 132, and is. driven by a drive motor 144 to a rotary movement about the axis of rotation 142.

The radial cutter disc 140 has protruding cutter teeth for milling the base section 112 of a cavity 110; axially, it has protruding teeth 148 for milling the recess sections 114.

The drive motor 144 and the milling disc 140 suspended therein can be automatically raised or lowered by a lifting device 150 along the axial direction 151 of the milling disc 140. The lifting device 150 and the driving motor 144 they are housed in a drive unit 152 of the milling equipment 130, which - relative to the housing 132 - can be moved by a hand cable 154 along a radial displacement direction to the axis of rotation 142 of the milling disc 140 and vertical to the front stop surface 156.

Lifting device 150 for axial movement of the milling disc 140 may consist of a normal electric motor with transmission or stepper motor. The energy required for the lifting movement may be

generated through a power supply or generator coupled to the main drive spindle of the milling equipment 130.

The generator can be executed especially in the form of eddy current coupling, where a variable adjustment torque can be transmitted to a lifting mechanic, which mechanically and without using an additional motor transposes this torque in a lifting movement. milling disc 140, for example by means of sector distribution or by means of an oscillating plate. The travel distance of the milling disc 140 when it is raised or lowered along the axial direction 151 by operating the lifting device 150 can be adjusted by means of a selector switch or with CNC control.

The working mode of the milling equipment 130 described above is as follows:

The milling equipment 130, with its front bearing surface 136, is placed in contact with the contact surface 106 of the component (e.g. of the first component 102) in which the cavity is desired.

Next, the milling disc 140 is rotated and with handle 154 is moved out of the housing 132 against the component to be worked, so that the milling disc 140 cuts a basic section 112 into component 102 shaped cylinder cover section with increasing cavity depth. (See Fig. 12).

When the desired depth of cavity T has been reached, the lifting process of the milling disc 140 is initiated by the lifting device 150, where the milling disc 140 is moved upwards along the axial direction 151 to desired width b of indentation section 114. At the same time, the disc will be cutting the upper indentation section 114 of cavity 110 with axial teeth 148. (See Fig.13). Next, the milling disc 140 is moved downwardly back to the starting position and beyond it to the desired width b of the indentation section 114, while the axial teeth 148 of the disc 140 cut the indentation section bottom 114. (See Fig. 14).

When the lower recess section 114 has also been milled, the milling disc 140 is moved along the axial direction 151 up to the starting position and removed from the cavity 110 along the travel direction 156 by pulling. back the hand cable 154. (See Fig. 15).

The lifting process can be released, for example, by means of a manual key on the milling equipment 130.

Alternatively, it may be provided that the milling equipment 130 includes a depth sensor that automatically triggers the lifting process of the lifting device 150 when the desired depth T of the cavity has been reached, ie when the milling disc 140 has been reached. moved out of housing 132 to a predetermined distance.

Once the lifting process has been triggered, it proceeds in time, that is, the movement of the milling disc 140 upwards along distance b, then the movement of the milling disc 140 downwards along the distance 2b and the final movement of the milling disc 140 upwards along distance b to the starting position. Movement of the milling disc is automatic by controlling the lifting device by means of a control device (not shown) of the milling equipment 130.

In this way the cavity 110 with the receding sections 114 can be made simply in the same work step.

Alternatively to milling equipment 130 shown in

10 and 11, the milling equipment 158 shown in Fig. 16 may also be used to make the cavities 110 in the components 102 and 104.

This cutter equipment 158 includes an electric drive unit in an insulated housing 160 and a mechanical head 162 suspended thereon with a T-cutter 164 rotating about a rotational axis 166.

The T-cutter 164 includes a cable component 168 whose diameter is equivalent to the diameter B of the base section 112 of the cavity 110 to be milled, and a head 170 whose diameter equals the sum B + 2b of the widths of the base section 112 and the indentation sections 114.

The milling equipment 158 further includes a guide device 172 for orienting the milling equipment 158 in a pre-milled guide slot 174 (See Figs 17 and 18). The guide device 174 is a guide element

quadrant-shaped front 174 arranged before the T-cutter 164 in the direction of movement of the cutter equipment 158 during the milling process; its thickness is essentially equivalent to the width B 'of the pre-milled guide slot 174.

In addition, the guide device 172 includes a substantially quadrant-shaped rear guide member 178 disposed after the T-cutter 164 in the direction of movement; its thickness is essentially equivalent to the width B of the basic section 112 of the cavity 110 to be milled.

In addition, the rear guide element 178 has two guide teeth 180 arranged immediately after the head portion 170 of the T-cutter 164 extending in the direction of the thickness of the rear guide element 178 to the desired width b of the ends. indentation sections 114 of the cavity 110 to be milled, respectively up and down.

With the milling equipment 158 described above, the cavity 110 will be formed in the contact surface 106 of the first component 102, for example as follows:

First, a cylinder cover section-shaped guide slot 174 is made with a milling equipment already known and therefore not described in detail here; guide groove 174 will have the depth 丁 equivalent to the depth of the cavity 110 to be milled and its width B 'is smaller than the width B of the basic section 112 of the cavity 110 to be milled (see Figs 17 and 18).

The width B 'of the guide slot 174 may have, for example,

approximately 4 mm. Thereafter, the guide groove 174 is enlarged through the milling equipment 158 to form the desired cavity 110 with the receding sections 114.

To do this, the front guide element 176 of the guide device

172 is inserted into the guide groove 174 until the cylinder cap segment-shaped surface 182 of the front guide member 176, which has the same radius of curvature as the guide groove 174, is level and in contact with the bottom. guide groove 174, while the T-cutter 164 is still before the contact surface 106.

Next, the milling equipment 150 is rotated so that the cover surface 182 of the front guide element 176 slides into the bottom surface of the guide groove 174, curved, arc-shaped, and thereby the T-cutter 164 goes deeper into the first component 102, milling as much the extended basic section 112 of the cavity 110 as its respective setback sections 114 (see Figs. 19 and 20).

Guide teeth 180 disposed in rear guide member 178 run in recess sections 114 of cavity 110 formed by the T-cutter, and thus create an additional guide for the cutter equipment 158. The cutter equipment 158 continues to be turned to the

guide slot 174 until T-cutter 164 exits component 102 at the end opposite the starting point of guide slot 174 and until guide teeth 180 are no longer in contact with recess sections 114 of formed cavity 110 .

At this time the milling equipment 158 may be removed from component 102; cavity 110 as well as recession segments 114 are ready (see Figs. 21 and 22).

After making the cavities 110 in the first component 102 and the second component 104, an access hole 128 is made in the first component 102, joining the main surface 129 with the basic section 112 of the cavity 110. The connecting means 100 that joins together components 102 and 104 between

itself includes a first connecting element 184 to be inserted into the cavity of the first component 102 and a second connecting element 186 to be inserted into the cavity 110 of the second component 104 as shown in Figs. 5 to 7. The first connecting element 184 essentially consists of a

a barrel-shaped housing 188 with a curved bearing surface 190 in an arcuate shape, the arc shape being longitudinally longitudinally cut 192 of the connecting member 184. In addition, it consists of a surface of positioning 194, opposite the bearing curve surface 190, and two lateral surfaces 198 essentially parallel to the connection direction

196. From the lower edge of each side surface 198 rises a curved, arc-shaped clamping projection 200 in the longitudinal direction 192 and in a direction of vertical thickness 202 the direction of the connection.

Each of the mounting projections 200 towards the surface of

194, and is limited by a bearing surface 204, which is arc-shaped to the longitudinal section along the longitudinal direction length 192.

From the side not facing the positioning surface 194, each mounting projection 200 is limited by an equally curved, arch-shaped bearing surface to the longitudinal section longitudinally 192, connected and flush with the bearing surface 190 of the housing. 188.

The bearing surface 204 and the bearing surface 206 of each attachment projection 200 are joined together by a lateral surface 208, essentially parallel to the longitudinal direction 192 and parallel to the connection direction 196.

The profile of each clamping projection 200 corresponds essentially to the recess section profile 114 of the corresponding cavity 110 respectively, and the curvature of the clamping projection 200 corresponds to the curvature of the corresponding receding segment 114, so that it is the first connecting element 184 may be inserted with its fastening projections 200 into indent sections 114

110, where it can be moved by sliding. The first connecting element 184 further includes a receiving chamber 210 enclosed by housing 188 for receiving the fixing element 212, which may exit through an opening 214, wherein the receiving chamber 210 flows into the positioning surface 210.

Reception Chamber 210, on its non-facing side

positioning surface 194 may extend into the curved support surface 190.

Fastener 212 includes a plate-shaped base body 216 having ring-shaped elevations 218 at one end surrounding the polygon-section receiving opening 220 aligned with a substantially circular through-hole 222 in one of the lateral surfaces 198 of housing 188.

The ring-shaped elevations 218 abut the brackets disposed on the receiving chamber 210, so that the securing member 212 is secured to the housing 188 so that it can rotate around the central axis 224 of the receiving opening 220.

The free end of the fastener 212, not facing the ring elevations 218, has arc-shaped protrusions 226 protruding on both sides of the base body 216 in the direction of thickness 202.

In addition, the first connecting element 184 has on both sides of the opening 214 of the receiving chamber 210 a

socket projection 228 whose shape is essentially of a hub 230, extending from the positioning surface 194 to the connection direction rod 196 and tapering towards the far end of the positioning surface 194 to facilitate insertion into a receiving recess 232 of the second connecting element 186, respectively, complementary to pin 230.

The locking projections 228 of the first connecting element 184, in the direction of thickness 202, exactly fit into the receiving recesses 232 of the second connecting element 186, so that the locking projections 228, in the direction of thickness 202, they can absorb shear forces from the connection between components 102 and 104, and additional pins can be dispensed with as required by most other connection means.

In the longitudinal direction 192, on the other hand, the receiving recesses 232 exhibit a larger expansion than the locking projections 228, so that the first connecting element 184 and the second connecting element 186 can be moved relative to each other. longitudinally, allowing compensation of connection tolerances between components 102 and 104.

The second connecting element 186 also includes an essentially sectional cylinder shell housing 234 having curved bearing surface 190 in an arc-shaped manner, the arc being in longitudinal longitudinal section 192 of the connecting element. 186. In addition, it consists of a positioning surface 194, opposite the curved support surface 190, side surfaces 198, mounting projections 200 protruding from the side surfaces 198 in the direction of thickness 202, with curved support surface 204 facing for positioning surface 194, a bearing surface 206 flush with bearing surface 190 and a lateral surface 208.

As can be seen from Fig. 6, the housing 234 of the second connector 186, in addition to the receiving recesses 232 for the socket 228 projections of the first connector 184, has an inlet chamber 236 centrally disposed between the receiving recesses 233, which opens into an opening 238 in the positioning surface 194 and which may extend into the bearing surface 190 of the opposite side.

From both sides of aperture 238 stand retaining projections 240 with a curved arcuate retaining surface 242 in the direction of thickness 202 into the inlet chamber 236, so that between the two retaining projections 240 remains a gap whose width is slightly greater than the thickness of the base body 216 of the fastener 212 of the first fastener 184. To produce a separable connection between the first fastener

102 and ο the second component 104 through the connecting means 100 between ο the first connecting element 184 and ο being connecting element 186,

proceed as follows: Firstly the first connection element 184, as shown in Fig. 23, is inserted into the cavity 110 of the first component 102 such that the fastening projections 200 of the first connection element 184 fit into the securing sections. recess 114 from cavity 110 and through-opening 222 on side surface 198 of housing 188 is aligned with access port 128 in first component 102 (see Fig. 24).

Likewise, the second connector 186 is inserted into the cavity 110 of the second component 104, whose attachment projections 200 fit into the recess sections 114 of the cavity 110, and the housing 234 of the second connector 186 is practically housed in the housing. well 110 (see Fig. 24).

The fastener 212 of the first connection element 184 is first fully facing into the receiving chamber 210 of the first connection element 184 (see Fig. 24).

In this freeze position of the fastener 212 the two components 102 and 104 may be moved against each other until the contact surfaces 106 and 108 as well as the positioning surfaces 194 of the connection elements 184 and 186 are flush and the mating projections 228 of the first connecting member 184 are engaged with the receiving recesses 232 of the

second connecting element 186 (see Fig. 25). At this point, the actuating end of an angled Philips wrench 244 is inserted through the access hole 128 in the first component 102 and the through opening 222 in the housing 188 of the first connecting element 184 to the receiving recess 220 of the fastener 212 , being connected to recess 220 (see Fig. 25).

Next, the fastener 212 is rotated out of the receiving chamber 210 of the first connecting element 184 with a Philips 242 wrench, so that the arc projections 116 of the fastener 212 pass through the opening 238, reaching the camera 236 of the second connection member and fit behind the retaining projections 240.

The curvature of the arc projections 226 of the fastener 212 on the one hand, and the curvature 242 of the retaining projections 240 on the other hand are designed such that the two connecting elements 184 and 186, - by pivoting The fastener 212 into the inlet chamber 236 is pulled increasingly towards the direction of the connection 196, forming a large contact surface between the retaining surfaces 242 and the projections. arch 226 of the fastener 212.

Thus, compressive stress points are avoided at the contact surfaces between the retaining projections 240 and the arc projections 226 of the fastener 212, and the strength of the material of which the fastener 212 and the housing 234 of the fastener are formed. second connection element, and is exploited as homogeneously as possible.

The fastener 212 and the housings 188 and 234 of the connection elements 184 and 186, therefore, may be made especially of an injectable plastic.

The fastener 212 during connection effort between the connecting elements 184 and 186 undergoes swallowing and compressive forces to the long of the connecting direction 196; however, bending moments are small and can be neglected. The receiving chamber 210 of the first connecting element 184, the

input chamber 236 of the second connection element 186 and the end tale of the connection elements 184 and 186 may be produced in one handle.

The securing member 212 may be inserted into the receiving chamber 210 through the opening of the receiving chamber 210 on the bearing surface 190 of the first connecting element 184, so that the housing 188 of the first connecting element 184 need not be divisible.

Therefore, it is not necessary for the housing 188 of the first connection element 184 to be constructed in half shell shape, thus increasing the strength of the first connection element.

184. Since the curved bearing surfaces 190 of the connecting members 184 and 186 have the same radius of curvature as the bottom surfaces 118 of the cavities 110, with which the bearing surfaces 190 are slidable and in contact, and may slide; as the fastening projections 200 of the connection elements 184 and 186 can be moved tangentially, without much effort, in the recess sections 114 of the cavities 110 and, therefore, the connection elements 184 and 186 still have a degree of freedom of movement in establishing the connection, it is still possible to make corrections regarding the relative position of the connecting elements 184 and 186 to each other when connecting the components 102 and 104.

This considerably reduces the accuracy requirements ereferent to the position of the wells 110 in the components 102 and 104, providing considerable ease to the user. When the fastener 212 is passed from the released position

shown in Fig. 25 for the fixed position of Fig. 26, the pulling forces acting on the connecting elements 184 and 186 in the connecting direction 196 will create such a strong static frictional force between the bearing surfaces 204 of the projections 200 , on the one hand, and with the recoil surfaces 122 (in contact with the surfaces 204) of the recess sections 114 of the cavities 110, on the other hand, which is the degree of remaining freedom of movement described above and nullified and a connection

completely fixed and established between the components 102 and 104. Through the support of the securing projections 200 on the recess surfaces 122 of the recess sections 114 of the cavities 110 in the components 102 and 104, the connecting elements 184 and 186 are anchored with safety in the respective component 102 or 104.

In the fixed position, shown in Figs. 7 and 26, the fixing element

212 acting in conjunction with the retaining projections 240 prevents relative movement of the first connecting member 184 and the second connecting member 186 to the connecting direction line 196.

To separate component 102 from component 104 it is only necessary to reconnect a Philips 244 wrench with the receiving chamber 220 of the fastener 212, (passing through the access hole 128 in the first component 102), and move the fastener 212 by turning it. in the opposite direction to the fixed position for the released position of Fig. 25, in which the arc projections 226 of the securing member 212 are no longer connected with the retaining projections 240 of the second connecting element 186, so that the connecting elements 184 and 186 can be easily separated from each other when moved along the connecting direction 196.

As can be seen from Figs. 27 to 31, the profiles of the clamping projections 200 need not be exactly rectangular as shown in Fig. 28.

It may also be provided that the fastening projections 200

have a trapezoidal profile that tapers as they move away from the lateral surfaces 198 of respective housing 188 or 234, as shown in Fig. 29.

Alternatively, it may also be provided that the profile of the clamping projection 200 is tapered as it moves away from the corresponding lateral surface 198, as shown in Fig. 30.

In addition, it may be provided that the fixing projection profile 200 has a curved outer contour, at least in some sections, for example a semicircular outer contour, as shown in Fig. 31. A second embodiment of a medium connection 100,

shown in Figs. 32 to 34, differs from the first embodiment shown above by the fastener element 212 of this second model having the shape of the rose member 246 with outer rose 248, which is connected to the inner rose 250 of a retaining member 252 of the second connecting member 186 for effecting the connection between components 102 and 104.

As can be seen from Fig. 33, the thread member 246 of the first connecting member 184 includes, in addition to the outer thread 248, a cylindrical upper portion 254 with a central receptacle 256 for the drive handle of a drive member (not shown), for example, a Philips screwdriver or a screwdriver, with the receiving 256 having a polygonal cross-section complementary to the

cross section of the drive section. Between the upper (head) 253 and the outer thread 248 of the thread member 265 is a rod 258, the diameter of which is smaller than the upper part 254.

Top 254 and rod 258 are arranged in a stepped receiving chamber 160 of housing 188 of first connection member 184; the receiving chamber 160 has a lower section of the larger diameter chamber 262 and an upper section of the smaller diameter chamber 264, and the two chamber sections 262 and 264 pass through a section 266, where the upper part rests. 254 of the rose element.

The upper section of the chamber 264 extends upwardly from the direction of connection 196 and ends at the positioning surface 194 of the first connection element 184.

Roseate 246 which serves as a fastener 212 may thus be rotatable about a rotary axis 268 arranged parallel to the direction of the connection 196 on the first connection element 184.

The retaining member 252 of the second connecting member 186 has a quadrant-shaped outer contour and is secured to a quadrant-shaped receiving chamber 270 in the housing 234 of the second connecting member 186 to the longitudinal direction lobe 192; The retaining element 252 can be moved,

but it cannot be rotated. The receiving chamber 270 is traversed by an access channel 272 extending to the direction of connection 196 of the positioning surface 194 of the second fastener 186 passing through the receiving chamber 270 to the curved bearing surface 190 of the housing. second fastener 186; receiving chamber 270 has elongate, essentially oval cross-section.

To connect the first component 102 to the second component 104, the first connecting element 184 and the second connecting element 186 of the second embodiment of the connecting means 100 are inserted into the respective cavities 110 of the first component 102 and the second component 104.

Thereafter, the second component 104, together with the second connection element 186, is placed under the first component 102 with the second connection element 184, such that the outer thread 248 of the thread member 246, - passing through access channel 272 of the second connecting member 186 - extends to the receiving chamber 250 and is connected to the inner thread 270 of the retaining member 252.

Immediately after, the thread member 246, through a drive element (not shown; for example, a screwdriver) which passes through the access hole in the first member 102 and fits in the socket 256 at the top 254 of the member rosea 246 -, and

is rotated about the rotational axis 268 so that the outer thread 248 of the thread member 246 is rotated into the inner thread 250 of the retainer 252 and thus the second connecting member 186 is pulled against the first connecting member 184, until the position shown in Fig. 34 is reached, in which both connecting members 184 and 186 are flush with their positioning surfaces 194, while the outermost thread 248 extends. beyond the header 270 to the section of the access channel 272 Located between the receiving chamber 270 and the bearing surface 190 of the second connection member 186. For the drive element to connect to the header

256 in the upper part 254 of the thread member 246, the access hole in the first component 102 in this embodiment of the invention, and coaxial to the rotary axis 268 of the thread member 246, and thus parallel to the direction of connection 196. The separation two components 102 and 104 in this model of

The invention is carried out as follows: with ο the drive element (not shown) it rotates the thread element in the opposite direction so that the outer thread 248 is rotated outwardly from the inner thread 250 of the retaining element. 252 until the thread member 246 is no longer connected to the retaining member 252 and the second connecting member 186 can be decoupled from the first

184. In view of the fact that the retaining element 252 can be moved in the longitudinal direction 192 and considering the elongated cross-section of the access channel 272, a certain relative movement between the rose member 246 and the housing is possible. 234 of the second connection member 186 by establishing the connection between the first component 102 and the second component 104, which in turn enables compensation of positioning tolerances of the cavities 110 in components 102 and 104 to be compensated.

The second embodiment of connection means 100, shown in Figs. 32 to 34, has no projections of engagement with the first connection element 184; however, as in the first embodiment, it has fastening projections 200 on the connection elements 184 and 186.

Moreover, the second embodiment of connection means 100, shown in Figs. 32 to 34, with respect to assembly and operation, coincides with the first embodiment, shown in Figures 1 to 31, to which is described above. ζ referendum in this regard.

A third embodiment of a connecting means 100, shown in Figs. 35 to 39, differs from the first embodiment shown above by the housing element 188 of the first connecting element 184 having an elevation 274 in shape.

The seat between the two locking projections 228, which in the connected state of the components 102 and 104 fits into a recess 276, complementary to the housing 234 of the second connecting element 186 (see Fig. 37).

Between the elevation 274 and the undercut 276 there is a clearance in the longitudinal direction 192, enabling compensation of positioning tolerances between the cavities 110 of the components 102 and 104 to be compensated.

In this embodiment, the fastener 212 of the first connection member 184 has a rosette member shape 278 which includes a support section 280 with inner rosette 282 and a shaft section 284 extending downwardly from the screw section. support 280 to link direction drone 196; axis section 284 has a diameter smaller than support section 280; The locking member 212 further includes a drag member 286 which projects the bracket portion 280 in axial direction downwards (see especially Fig. 38). As can be seen mainly from Fig. 36, the roseate element

278 is arranged in a stepped receiving chamber 288 of the housing 188 of the first connecting member 184; the receiving chamber 288 has a lower section of the larger diameter chamber 290 and an upper section of the smaller diameter chamber 292, which join into a section 294.

The screw member 278 is disposed in the receiving chamber 288 and can be rotated about a rotary axis 296 arranged parallel to the

In order to drive the rotational movement of the thread member 278 about the axis 296, in the lower section 290 of the receiving chamber 288 there is also provided a hollow cylinder-shaped magnetic element 298 arranged coaxially to the wing member. 278; The magnetic element 298 is partly on the shaft section 284 of the rosette element 278 and has a drag element 300 on the front facing the support section 280, which protrudes in axial direction (see especially Fig. 38).

The magnetic element 298 is comprised of a permanent magnetic material (diametral magnetization) magnetized essentially vertically to its longitudinal axis and thus vertical to the rotary axis 296.

The diametrically magnetized magnet element 298, placed on the shaft section 284 of the screw element 278 so that it can rotate about the axis 268, can be driven to perform an oscillating rotary movement about the axis 296 through a magnetic field of. drive external to the connecting means 100 which acts on the magnetic element 298 and may vary with time. This oscillating motion connecting the drag member 300 of the magnetic member 298 with the drag member 286 of the member 278 causes a pivoting movement of the member 278 around the member.

296. For this purpose, drive equipment 302, shown schematically in Figs. 38 and 39, including a housing 304, for example of synthetic material, an electric motor 306 installed in housing 304 with a shaft, is used. 308 and a drive magnet 310 connected to the 308 shaft with torque resistance.

The drive magnet 310 is a permanent high performance cylindrical magnet (diametral magnetization), magnetized essentially vertically relative to the longitudinal direction 312 of the drive shaft 308.

To create the rotary motion of the rosy element 278, the procedure is as follows:

The drive device 302 is positioned relative to the first connecting element 184 such that the longitudinal direction 312 of the drive shaft 308 of the drive device 302 and the rotary axis 296 of the rose member 278 are parallel to each other and the distance between the drive magnet 310 and the magnetic element 298 are as small as possible to achieve the strongest possible interaction between the two magnets. The positioning of the drive equipment 302 and the magnetic element 298 in this situation is shown schematically in Figs 38 and 39.

Then the electric equipment motor 306 of

308 so that the drive shaft 308 and with it the drive magnet 310 (viewed from the direction of view indicated by the arrow 39 in Fig. 38) rotate clockwise, for example, the north pole (N ) and south (S) of the drive magnet 310, clockwise rotation, depending on the diametrical magnetization of the drive magnet 310, as shown in the schematic embodiment of Fig. 39.

The rotational motion of the drive magnet 310 thus creates a rotating magnetic field, which varies over time.

In order that this driving magnetic field can enter the inner space of the first connecting element 184 and thereby interact with the magnetic element 298, the housing 188 of the first connecting element is made of non-ferromagnetic material, for example a synthetic material.

Since the opposite poles of the magnetic element 298 and the drive magnet 310 attract and the equal poles of these element repel each other, the magnetic element 298 rotates in the opposite direction within the receiving chamber 288 due to interaction with the drive magnet. 310, ie counterclockwise (seen in the direction of gaze indicated by the arrow 39 in Fig. 38).

Through this pivoting movement, the drag element 300 of the magnetic element 298 joins the drag element 286 of the screw member 278, so that the screw element 278 is driven by the magnetic element 298 at a pivoting motion about axis 296.

in the same direction of rotation as the magnet element 298. the magnet element 298 and the screw element 278 dragged by it accompany the rotational movement of the drive magnet 310 until the resistor (which acts, for example, because the internal rose 282 of the thread member 278 and rotated about a complementary outer thread 314 of a retaining member 316 provided in the second connecting member 186) - acting on the thread member 278 is so large that the torque transmitted by the rotating magnetic field created by the magnetic element 310, is no longer sufficient to continue rotating the screw element 278. When such a locking point is reached, the screw element 278 and the magnetic element 298 are stopped in the position they have reached while the drive magnet 310 continues spinning

When the drive magnet 310 has rotated approximately 180 ° more so that the equal poles of the drive magnet 310 and the magnetic element 298 are directly facing each other, the magnetic element 298, in a reversing process, will begin to move again. , in the same rotational direction as the drive magnet 310, until the reverse poles of the drive magnet 310 and the magnetic element 298 face each other again. Reached this situation, the direction of rotation of the magnetic element

298 will reverse again and the magnetic element 298 will again rotate in the opposite direction to the magnetic element 310, as in the previous phase.

locking the roseate element. The magnetic element 298 is then accelerated about half a turn past the rotating magnetic field of the drive magnet 310 until the drag element 300 again touches the drag element 286 of the rose member 278 and the thrust of the magnetic element 298. is suddenly transmitted to the drag element 286 and with it to the rose element 278. With this large pulse transmission the rose element 278 can detach from its locked situation and rotate at a certain angle to a position in which it occurs again. locking of the thread member 278. In this new locking position, the magnet element 298 is also stopped again, unable to follow further the drive magnet 310, until the equal poles of the magnet element 298 and the drive magnet 310 are facing again. forward and a new process of reversing the magnetic element 298 enables a new take-off.

Through this periodic repetition the rose element 278 continues to be rotated from lock position to lock position. The repeated thrust on the drag element 300 against the drag element 286 causes a hammering effect that accelerates the pivoting movement of the screw member 278 about the axis 296 against the resistor.

Further details for driving the rotary movement of the thread member 278 through an external drive magnet 310 are in DE 198 07 663 A1, which we refer to in this regard and are therefore integral to the present. description.

With the pivoting movement thus created for member 278, the inner thread 282 of the thread member 278 may be screwed with the outer thread 314 of the retaining member 316 disposed on the second connecting member 186, or may be unscrewed from the outer thread 314 through reversing the direction of rotation of the drive magnet.

The retaining member 316 in this embodiment includes a square head 318, inserted loosely into a square receiving chamber within the housing 234 of the second connector 186, being secured against rotation around the direction of the connector 196.

From the bottom of the square head 318 extends the outer thread 314 of the retaining member 316 to an access channel 322 parallel to the connection direction 196 into recess 276 of the second connecting member 186 of such that this outer thread 314 faces each other with the inner thread 282 of the thread member 278 on the first connecting member 184 (see Figs. 35 and 36).

As can be seen from Fig. 37, the receiving chamber 320 also contains a pressure spring 324 which pre-tensiones the retaining element 316 longitudinally the direction of the connection 196 to the first connection element 184.
