Abstract
Description
Technical Field
[0001] The invention relates to an anchoring point component, comprising a lower component with a connecting element for connecting the anchoring point component to an object to be fixed or manipulated with the anchoring point component, and an upper component rotatable relative to the lower component around the longitudinal axis of the connecting element. Background Art
[0002] Such anchorage components are usually used for lifting objects. The anchorage component is connected with its lower part via a connecting thread designed as a bolt to the object to be lifted, wherein a plurality of anchorage components are usually used for lifting the object in order to attach the corresponding lifting rigging. In order to orient the lifting eye in the same direction as the tensile force acting on it when a lifting device hung on the lifting eye is acted upon, the lifting eye is rotatable relative to the connecting thread. The same properties of the lifting eye are also desired when the lifting eye is used to tie down an object.
[0003] The anchor point component usually remains on the object to be lifted or fastened only during lifting or fixing. Therefore, this lifting eye is screwed into the threaded hole of the object to be manipulated, which is provided for this purpose and equipped with a complementary internal thread, by means of a connecting screw provided with a threaded section. If the anchor point component is no longer needed, the anchor point component is screwed out of the object again. Therefore, frequently screwing in and out of this anchor point component belongs to the typical operation required when it is used. In order to simplify this process, it is stipulated in the document DE 44 03 785 A1 that a screwdriver that can be coupled with the head of the bolt is connected to the lifting eye, and the screwing movement to the connecting screw is implemented through the lifting eye by the screwdriver. It is stipulated here that the connecting screw is designed as a hexagon socket screw, for example, and the screwdriver includes an adapted tool. The screwdriver itself includes a bow-shaped member that guides around the arc portion of the lifting eye in order to connect itself to the lifting eye and to introduce torque. If the hexagonal tool of the screwdriver is placed in the hexagonal recess of the connecting thread, the connecting thread is connected to the eye in a torque-locked manner after overcoming the play that may exist between the arc of the eye and the bow. As a result, the connecting thread can be operated by the rotational movement of the eye without the need for additional tools. In order to connect the screwdriver to the eye, the bow of the screwdriver surrounding the eye has a widened opening, through which the arc of the eye is guided so that the screwdriver is connected to the eye. In order to achieve the torque transmission from the eye to the connecting thread, so as to not only achieve the loose screwing in or loose unscrewing out of the threaded hole of the object, but also achieve the prescribed fixing of the connecting thread and thus the prescribed fixing on the anchor point component of the object, the screwdriver must have sufficient stability. The necessary provision of a widened mounting hole in the area of the bow will react to this in a certain way. Therefore, certain requirements are placed on the screwdriver.
[0004] A further anchoring point component is known from patent document DE 43 36 779 C2, which is designed so that the torque for connecting the bolt to the object to be manipulated can be introduced into the lower part or its bolt through the upper part. The upper part of the anchoring point component has a hood-shaped connection part, through which the upper part is connected to the lower part. The hood-shaped connection part extends over the entire upper side of the lower part, whereby the screw head is also completely covered. Therefore, it is possible to prevent contaminants from entering the screw head and the lower part. An inner hexagonal profile is provided in the inner side of the hood-shaped connection part, into which the screw head of the bolt, which is designed as a hexagonal head, is embedded when the torque is to be transmitted from the upper part to the bolt. The upper part is axially movable relative to the lower part. Once a force having a component axially oriented relative to the longitudinal axis acts on the upper part, the engagement of the screw head of the bolt of the lower part with the torque engagement of the rotation transmission profile of the upper part is cancelled. The rotation transmission profile of the upper part is then pulled out from the screw head. When the screw head has completely moved out of the rotational drive contour of the upper part, the upper part can rotate freely relative to the lower part.
[0005] However, in this prior art, it is not possible to apply a torque to the screw head of the bolt by means of a tool. In the case of such known anchoring components, their handling is not completely problem-free either, since special care is required when introducing forces into the anchoring component, in particular when the forces acting on the upper part are not aligned with the axis of rotation of the anchoring component. In the case of forces acting on the upper part with a shear component, the upper part usually attempts to rotate in the direction of the applied force. In order to avoid the risk of the bolt and therefore the anchoring component being unintentionally loosened from the object to be manipulated when such forces are introduced into the upper part while the upper part is still engaged in a torque-locked manner with the screw head, the upper part must be manually moved relative to the lower part into a use position of the anchoring component in which it can rotate freely relative to the lower part. However, this is time-consuming and cumbersome.
[0006] In order to avoid the above-mentioned problems described in DE 43 36 779 C2, an improved anchoring point component was developed, wherein the upper component is displaced axially relative to the lower component counter to the restoring force of the restoring spring or the restoring spring device, wherein in a first position the upper component is freely rotatable relative to the lower component, and in a second position the upper component acts rotatably on the screw head of the bolt. The bolt has an outer rotation synchronization profile, in particular a hexagonal rotation synchronization profile. The upper component has rotation synchronization cams protruding from the sides facing each other in the region of the roots of its two eyelets. When the upper component is freely rotatable relative to the lower component, the rotation synchronization cams are located above the screw head at an axial spacing observed from the threaded shank direction of the bolt. If the upper component moves in the direction of the lower component counter to the force of the restoring spring or the restoring spring device, the screw head is located between the rotation synchronization cams of the upper component with two mutually parallel rotation synchronization surfaces, so that as the upper component rotates, a torque is input into the screw head of the bolt and the screw head is driven to rotate thereby. Such an anchoring point component is known from document DE 202019 102 552 U1.
[0007] Even if the anchoring point component basically meets the mechanical requirements imposed on it, it is still desirable that the anchoring point component be designed to be compact with respect to the necessary height. Summary of the invention
[0008] Therefore, based on the discussed prior art, the technical problem to be solved by the present invention according to the anchoring point component of DE 20 2019 102 552 U1 is to provide an anchoring point component which can be designed to be compact in terms of its necessary height while maintaining the advantageous properties of the aforementioned anchoring point component.
[0009] The technical problem is solved according to the invention by an anchoring point component, which comprises a lower part with a connecting element for connecting the anchoring point component to an object to be fixed to the anchoring point component or to be manipulated, and the anchoring point component comprises an upper part that can be rotated relative to the lower part about the longitudinal axis of the connecting element, the upper part has a connecting part for connecting an anchor or a fastening part, the upper part can be displaced axially relative to the lower part counter to the restoring force of a restoring spring or a restoring spring device, in a first position the upper part can rotate freely relative to the lower part, and And in the second position, the upper part acts on the connecting element in a torque-cooperative manner, wherein the connecting element has a supporting disk protruding in the radial direction, and the upper part has a supporting disk support portion that supports the supporting disk on the radial side of the supporting disk, and wherein the connecting element has an outer rotation synchronization contour arranged at a distance from the supporting disk in the direction of the rod portion of the connecting element, and the upper part has a rotation synchronization contour adapted to the rotation synchronization contour, and the rotation synchronization contour of the upper part can be engaged with the rotation synchronization contour of the connecting element by axial displacement of the upper part from its first position to its second position.
[0010] In this anchor point component, the connecting element, for example, which is configured as a bolt, has a radially protruding support disk. The support disk is a part of the connecting element, which is connected to other parts of the connecting element at least in a torque-fitting (or torque-locking) manner. Usually, the support disk is formed on the connecting element. The rotation synchronization contour is located on the side of the support disk facing the rod, usually maintaining a certain distance from the support disk in the axial direction. The rotation synchronization contour is preferably located above the lower part, wherein, in this embodiment, the rotation synchronization contour is abutted on the top side of the lower part on its section surrounding the opening of the connecting element. The matching (or complementary, matching) rotation synchronization contour of the upper part is thus located below the support disk and is therefore located on the side facing away from the upper part. Through the axial mobility of the upper part relative to the lower part, the rotation synchronization contour of the upper part can be engaged with the rotation synchronization contour of the connecting element in the opposite direction to the restoring force of the return spring or return spring device. In this design of the anchor point component, it is preferred that the connecting element does not need to have a head in principle except for its support disk, in particular, it does not need to have a head with a special geometry designed for rotation synchronization. It is obviously possible to also equip the connecting element with a conventional screw head, which is however not an essential prerequisite for achieving the desired rotational synchronization between the upper part and the lower part. By arranging the rotational synchronization contour below the bearing plate of the connecting element, the annular base of the lower part and the upper part and thus the upper part can all be designed with a small height, which thus makes it possible to design the anchor point part compactly.
[0011] It is provided that within the scope of this embodiment, the rotational synchronization of the connecting element, such as a screw, by the upper part is described for the first time, wherein the rotational synchronization is not arranged on or in the screw head. An adapted rotational synchronization profile is arranged below the bearing disk, which allows a design of the anchor point part with a two-point support of the upper part relative to the lower part to be realized in a compact structure, wherein the two bearing positions between the upper part and the lower part are clearly spaced from each other in the axial direction of the connection mechanism. The first bearing position is the bearing of the bearing disk on the side of the connecting element in or on the bearing disk bearing of the upper part, which is supported on the upper part on its radial side. A second bearing position can be provided at a distance from the first bearing position and in a preferred embodiment. The second bearing position at a distance in the axial direction can be provided by an annular bearing projection of the upper part, which surrounds the outer side of the lower part. Usually, the bearing projection surrounds the lower part in a circumferential manner. As a result, the inner wall of the annular bearing projection of the upper part can be supported on the outer wall of the lower part. Due to this two-point mounting, in which the two bearing locations are spaced apart from each other in the axial direction, when transverse forces act on the connecting element of the upper part, which is designed as a lifting eye, for example, the transverse forces are particularly effectively transmitted to the lower part and the object to which the anchoring point part is connected. In a preferred embodiment, provision is made in the two-point mounting that the diameter of the lower part surrounded by the bearing projection of the upper part has a larger diameter, at least in the region of its adapted bearing section, than the diameter of the bearing disk of the connecting element. In this way, the upper part is supported on the lower part with transverse forces acting on a larger surface, and in particular directly adjacent to the surface of the object to which the anchoring point part is connected.
[0012] In one embodiment of such an anchoring point component, the shank section of the connecting element between its torque-engaging contour and the bearing plate is designed with a larger diameter than the shank section protruding from the lower part when the connecting element is designed as a screw with an outer contour. Due to the shank section with a larger diameter, the connecting element is designed to be stronger in its section that is particularly stressed (in the case of transverse loads on the upper part) and can thus absorb high transverse forces.
[0013] The torque synchronization profile that protrudes radially from the rod of the connecting element can be provided by a structure that is different from the above-mentioned profile in the radial direction, as long as the cross-section of the connecting element is non-rotationally symmetrical in the area of the torque synchronization profile. In one embodiment, it is provided that the connecting element has a radially protruding washer (Bund; or called a flange) or one or more washer segments as a rotation synchronization profile. This rotation synchronization profile washer can be implemented in a circumferential manner based on the rod of the connecting element. The basic geometry of the washer is non-rotationally symmetrical, and can be, for example, an ellipse or a polygon, usually with rounded edges. Preferably, the adapted rotation synchronization profile is designed so that the engagement position can be achieved in different angular positions of the upper part and the lower part relative to each other, for example, in every 90° angular position. In this case, when the rotation synchronization profile washer is arranged on the connecting element, the adapted rotation synchronization profile is designed to have a square cross-section, usually with rounded corners.
[0014] In one embodiment, the rotation-locking contour of the upper part is provided by a correspondingly continuous inner wall of a disk-shaped annular body protruding inwardly relative to the radial end of the bearing portion of the bearing disk. The disk-shaped annular body performs a dual function and, in particular, on the one hand, the radial inner wall of the annular body provides a rotation-locking contour with which the upper part can engage with the rotation-locking contour of the connecting element. On the other hand, the annular body, which engages the bearing disk from below and thus from behind in the direction of the connecting element, acts as a support to transmit the forces introduced axially into the eye to the connecting element.
[0015] The anchoring point part can be equipped with a connecting element designed as a screw. It is also possible that the connecting element is designed as an internally threaded sleeve. In this case, it is also possible that, in the case where a tool is to be used, the internally threaded sleeve is equipped with a screw head, which is arranged on the side of the internally threaded sleeve facing away from the lower part.
[0016] The return spring or the return spring arrangement is located between the upper part and the lower part. To support a compact design in the axial direction, the return spring or the return spring arrangement is preferably arranged partially in a circumferential groove, usually in a circumferential groove of the lower part. The return spring or the return spring arrangement protrudes out of the groove in the direction of the other parts only to the extent required for the axial mobility between the upper part and the lower part in order to achieve rotational synchronization.
[0017] In a preferred embodiment, it is provided that a wave spring as a spring ring is used as the return spring, because the wave spring has only a small height during assembly and still provides the necessary spring travel with sufficient force. This supports the compact design desired in the axial direction of such an anchoring point component. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The anchoring point component 1 is used to connect to an object so that the object can be manipulated, that is, the object can be lifted or tied down, etc., depending on the application. The anchoring point component 1 has a lower part 2 and an upper part 3. The upper part 3 is supported rotatably relative to the lower part 2. A pin 4, which is designed as a screw in the embodiment shown, is connected to the lower part 2 as a connecting element for connecting the anchoring point component 1 to the object to be manipulated or tied down. The pin 4 has a threaded section 5. The threaded section is used to connect the anchoring point component 1 to the object to be manipulated, which object should be equipped with an adapted internal threaded hole for this purpose. A support disc 6 is formed on the pin 4. The upper part 3, which is rotatable relative to the lower part 2 together with its pin 4, has an annular base 7, on which a lifting eye 8 is formed in the embodiment shown as a connecting element for connecting an anchor or a fastening element. A support disc recess 9 is provided on the base 7 as a support disc support. The support disc 6 of the pin 4 is accommodated in the support disc support.
[0032] exist Figure 1 and Figure 2 In the figure, the anchor point component 1 shows a first position of its upper part 3 relative to the lower part 2, and more specifically a freely rotatable position of the upper part 3 relative to the lower part 2, which is desired for the anchor point component in its intended use. Figure 3 As shown in the cross-sectional view of FIG. 1 , there is an axially acting wave spring 10 between the upper part 3 and the lower part 2, and the upper part 3 can be displaced axially toward the lower part 2 against the restoring force of the wave spring. The base 7 of the upper part 3 has a disc-shaped annular body 11 protruding radially inward, and the annular body itself is as shown in FIG. Figure 3 The ring 11 extending below the support plate 6 of the pin 4 is shown. The lifting force acting on the lifting ring 8 is transmitted to the pin 4 through the ring body 11 engaging the support plate 6 from the direction of the lifting ring 8 and below, and then to the object to be manipulated connected to the pin. Figures 1 to 3 In the position of the upper part 3 shown, the disk-shaped annular body 11 acts with its top side against the bottom side of the support disk 6 and is fixed in this position by the wave spring 10. In order to accommodate the wave spring 10, a circumferential groove 12 with a rectangular cross-sectional geometry is provided in the lower part 2, and the wave spring 10 is supported with its other end on the bottom of the groove.
[0033] In addition to its integrally formed bearing disk 6, the pin 4 also has a rotationally synchronous profile washer 13. The rotationally synchronous profile washer 13 is designed circumferentially in the form of a disk. Its radially outer peripheral geometry is not rotationally symmetrical and is designed as a square with rounded corners in the illustrated embodiment. The rotationally synchronous profile washer 13 is axially spaced apart from the bearing disk 6 and has a smaller maximum diameter than the bearing disk 6. The pin section 14 between the rotationally synchronous profile washer 13 and the bearing disk 6 has a larger diameter than the diameter of the threaded section 5. As a result, the pin 4 is designed in its pin section 14 to withstand particularly high shear forces.
[0034] The rotationally synchronized profile washer 13 is supported on the inner arm 15 of the groove 12 facing the upper part 3. The pin 4 is held on the lower part 2 in an axially positive manner by a connecting washer 16 as part of the pin 4, which engages in a matching connecting groove 17 of the lower part 2 that is open radially inwards. The connecting washer 16 and the groove 17 are matched to each other in terms of size so that the pin 4 can be inserted from above into the pin hole 18 of the lower part 2 with its connecting washer 16. In this case, the rotationally synchronized profile washer 13 also serves as a stop for limiting the insertion depth. Through this assembly process, the upper part 3 is simultaneously connected to the lower part 2.
[0035] The radial inner wall 19 of the disk-shaped annular body 11 of the upper part 3 has a contour adapted to the outer contour of the rotationally locking contour washer 13 so that when the two rotationally locking contours 13 , 19 mesh, a torque can be transmitted from the upper part 3 to the pin 4 , thereby connecting the two parts in a torque-locking manner.
[0036] Due to the fact that the rotationally locking contour of the pin 4 is designed as a circumferential disk-shaped washer, higher torques can be introduced into the pin.
[0037] The annular base 7 of the upper part 3 has an annular supporting protrusion 20 extending in the axial direction. The supporting protrusion 20 surrounds the lower part 2 from the outside in the radial direction. The inner side of the supporting protrusion 20 and the outer side of the lower part 2 are cylindrical surfaces, and are matched to each other in size, so that the radial inner wall of the supporting protrusion 20 is supported on the radial outer wall of the lower part 2. The upper part 3 is thus supported on the outer side of the lower part 2, and is supported on the radial side of the supporting disk 6 through the inner wall of its supporting disk recess 9. As a result, the upper part 3 is supported relative to the lower part 2 at two supporting positions L 1 , L 2 The above is completed, wherein the support position L in the figure 1 is the supporting position between the supporting protrusion 20 and the lower part 2, and the supporting position L 2The bearing position L is the radial inner side of the bearing plate support 9 and the radial outer side of the bearing plate 6 of the pin 4. Therefore, the bearing of the upper part 3 on the lower part 2 with its pin 4 or relative to the lower part 2 with its pin 4 is called a two-point bearing, wherein the two bearing positions L 1 , L 2 Keep a distance from each other in the axial direction. Two bearing positions L 1 , L 2 The spacing allows for a higher absorption of transverse forces. In the anchoring point component 1, the torque synchronization contours of the lower part 2 and the upper part 3 are arranged in a convenient manner at two bearing locations L using this spacing. 1 , L 2 This results in only a small necessary structural height in the axial direction of the annular base body 7 of the lower part 2 and the upper part 3. Accordingly, the transverse forces introduced by the upper part 3 act on the pin 4 with a correspondingly small lever.
[0038] In the embodiment shown, the bearing (or support) is designed as a sliding bearing (or sliding support). The support of the upper part relative to the lower part can be designed to be carried out through an intermediate connection of a bearing body, such as a ball or the like.
[0039] Figure 6 The cross section shows the rotational locking contour of the upper part 3 provided by the inner wall 19. The section plane is in the plane of the pin section 14 of the pin 4. The rotational locking contour of the upper part 3 provided by the inner wall 19 does not mesh with the rotational locking contour of the pin 4 in this position of the upper part 3 relative to the lower part 2. The anchoring point component 1 is thus in its first position, in which the upper part 3 is freely rotatable relative to the lower part 2. In order to transmit the torque from the upper part 3 to the pin 4, the upper part 3 moves axially in the direction of the lower part 2 against the restoring force of the wave spring 10, as indicated by the thick arrow. Due to the pushing movement of the upper part 3, the inner wall 19 of the disk-shaped annular body 11 meshes as a rotational locking contour with the rotational locking contour of the rotational locking contour washer 13 of the pin 4 (see in particular Fig. 9 ). In this position, a torque can be transmitted to the pin 4 via the upper part 3. This position of the upper part 3 relative to the lower part 2 is limited by the top side of the outer arm 21 that defines the groove 12. If the upper part 3 is released after the torque transmission is complete, for example, in order to screw the pin 4 with its threaded section 5 into a matching internal threaded hole of the object to be manipulated, the upper part is reset due to the energy stored in the wave spring 10 and pressed back into its freely rotatable position relative to the lower part 2.
[0040] The pin 4 of the illustrated embodiment also has a hexagonal head, wherein the pin 4 can be operated with a screw wrench if desired. The diameter of the rotational locking profile shim 13 of the pin 4 corresponds to the diameter of the screw head, so that equal torques can usually be introduced into the pin 4 via the screw head. As a result, a prescribed preload can be introduced into the pin without placing a screw wrench on the screw head, for example by using a lever that is partially passed through the opening of the eye 8 of the upper part 3. However, the torque cannot be measured subsequently, at least not smoothly. It is obvious that in addition to the pin 4 with its hexagonal head shown in the figures, the hexagonal head can also be provided with any other rotational locking profile, for example an inner rotational locking profile, such as a hexagonal rotational locking profile.
[0041] Fig.10 An anchoring point component 1.1 according to another exemplary embodiment is shown. This anchoring point component is constructed identically to the anchoring point component 1 and differs from the anchoring point component 1 only in its connecting elements. Figures 10 to 12 In the figure, the same technical features as those of the anchoring point component 1 shown in the previous figures are marked with the same reference numerals, but with the addition of the suffix ".1". In the anchoring point component 1.1, the connecting element is not designed as a bolt, but as an internally threaded sleeve. Thus, the rod 22 and the internal thread 23 form an internally threaded sleeve 24. Thus, the anchoring point component 1.1 is used to be connected to an object to be manipulated and / or to be fixed, from which a threaded rod protrudes, which has a thread that matches the internal thread 23 of the internally threaded sleeve 24.
[0042] Fig.11 A perspective view of an internally threaded sleeve 24 is shown. Its rotationally synchronous profile washer 13.1 and the support disk 6.1 axially spaced from the rotationally synchronous profile washer are clearly shown. The internally threaded sleeve 24 is provided with a screw head 25 in the direction of the suspension eye 8.1.
[0043] The functionality of the anchor point component 1 . 1 is identical to that described for the anchor point component 1 with regard to the rotational synchronization of the lower part 2 . 1 and the upper part 3 . 1 . Fig.10 The upper part 3 . 1 is shown, which engages with the rotation-synchronizing profile washer 13 . 1 of the internally threaded sleeve 24 . Fig.12 In contrast, the anchoring point part 1.1 is shown, which has an upper part 3.1 which is engaged in a torque-locking manner with the lower part 2.1.
[0044] The present invention has been described with the aid of embodiments. A skilled person can also obtain numerous other feasible solutions for implementing the present invention without departing from the effective scope of protection, and it is not necessary to list them in detail within the scope of this embodiment.
