Description

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The invention refers to a detachable locking/bolting connection arrangement for two components.

[0004] 2. Discussion of Background Information

[0005] Numerous detachable connection arrangements exist which make use of different connection principles (e.g. plug-in, lock-in, threaded connections).

[0006] To mount components with large surface areas (e.g. interior-wall paneling) several connection arrangements per component are often necessary to achieve a secure hold.

[0007] Installing components of this kind, especially with several connection arrangements per component, requires considerable skill and patience, especially where the work is done by one person only. The person will have to hold the component in position with one hand while making the individual connections with the other. If the component should slip out of position accidentally, a new attempt has to be made.

SUMMARY OF THE INVENTION

[0008] In order to avoid this disadvantage, the invention provides for a detachable arrangement which permits simple loose temporary fixing of the connection elements. For example, it should be possible to attach the component loosely by pressing it lightly onto the mounting frame in such a way that it can no longer drop off.

[0009] Thanks to this kind of loose connection, the installer can now use both hands to align the component and tighten the individual connection arrangements.

[0010] The invention also provides for a connection arrangement for detachably connecting two components having openings which are aligned with one another, wherein the arrangement includes a rotatable retaining bolt on the side of the first component which can be introduced into the openings. A bolt connector is attached to the second component. The rotatable retaining bolt has an exterior thread. The bolt connector has a housing with an interior taper tapering towards the opening for receiving the end of the rotatable retaining bolt. At least two shell-shaped threaded-nut segments are located in the housing. Each segment has an outer mantle with a bevel to fit the interior taper. The threaded-nut segments and their outer mantles can be moved on the interior taper towards or away from the housing opening. The threaded-nut segments are spring loaded towards the housing opening. The rotatable retaining bolt can be pressed in between the movable threaded-nut segments against the force of the spring in such a way that its thread locks into that of the threaded-nut segments and that the thread of the rotatable retaining bolt connects with the thread of the threaded-nut segments when the rotatable retaining bolt is rotated.

[0011] The threaded-nut segments may have a space between them and stops may be located on the interior wall of the housing which project into the spaces between the threaded-nut segments in order to limit the axial rotatability of the threaded-nut segments.

[0012] A spiral pressure spring may be located in the housing which presses the threaded-nut segments towards the opening in the housing.

[0013] The spiral spring may be located between the floor of the housing and a disk which can be moved in the direction of the axis of the rotatable retaining bolt and which lies against the threaded-nut segments.

[0014] The floor of the housing and the disk have an opening to guide the rotatable retaining bolt.

[0015] The housing may have an edge projecting outwards or edge-segments projecting outwards.

[0016] The outwardly projecting edge may be a flange for attaching a component.

[0017] The bolt connector may be located in a vibration-damping ring of a vibration-damping material, preferably rubber or elastomer.

[0018] The vibration-damping ring may be connected with the interior wall of an open hollow cylinder, which has a supporting edge pointing outwards or segments of a supporting edge pointing outwards.

[0019] The vibration-damping ring or the hollow cylinder can be located in the opening of the second component.

[0020] The second component may lie on the supporting edge or the segments of the supporting edge of the hollow cylinder or are connected to it (them).

[0021] A vibration-damping and/or anti-slip material may be located on the supporting edge or the segments of the supporting edge, or may be applied as a coating.

[0022] The edge or the edge segments may extend beyond the projection of the interior dimension of the hollow cylinder.

[0023] A centering ring with a beveled inner edge may be located above the opening of the housing.

[0024] A guide sleeve for the rotatable retaining bolt may be located in the opening of the first component. The guide sleeve may have a retaining edge lying against the first component, and resilient sleeve arms whose free ends have tappets which hook over the lower edge of the opening of the hole in the first component.

[0025] The invention also provides for a detachable connector for connecting with a threaded bolt wherein the connector includes a housing having an inner taper tapering towards the opening for receiving the end of the threaded bolt. At least two shell-shaped threaded-nut segments are located in the housing. Each segment has an outer mantle having a bevel to fit the inner taper. The threaded-nut segments and their outer mantles can be moved on the interior taper towards or away from the housing opening. The threaded-nut segments are spring loaded towards the housing opening. The threaded bolt can be pressed in between the threaded-nut segments against the force of the spring in such a way that its thread locks into that of the threaded-nut segments. The thread of the bolt is adapted to connect and/or threadably engage with the thread of the threaded-nut segments when the threaded bolt is rotated.

[0026] The threaded-nut segments may have a space between them and that stops are located on the interior wall of the housing which project into the spaces between the threaded-nut segments in order to limit the axial rotatability of the threaded-nut segments.

[0027] A spiral pressure spring may be located in the housing which presses the threaded-nut segments towards the opening in the housing. The spiral spring may be located between the floor of the housing and a disk which can be moved in the direction of the axis of the threaded bolt and which lies against the threaded-nut segments.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0052] The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description is taken with the drawings making apparent to those skilled in the art how the forms of the present invention may be embodied in practice.

[0053] FIG. 1 shows a sectional view of the detachable locking/bolting connection arrangement. The arrangement is shown connecting two components MP1 and MP2. The first component MP1 has a first opening HMP1 and the second component has a second opening HMP2. These openings HMP1 and HMP2 are aligned with one another.

[0054] The arrangement uses a rotatable retaining bolt 1 which is located on the upper side of the first component MP1. The bolt 1 can be introduced into the various openings formed in the components MP1 and MP2 and in the bolt connector. The bolt connector is attached to the second component MP2. In the embodiment shown in FIG. 1, the bolt connector includes elements 2, 3-1, 3-2, and elements 4, 5, 6, 7, 8 and 9.

[0055] The rotatable retaining bolt 1 has an exterior or external thread 1W. The bolt connector includes a cylindrical housing 2 which includes an inner taper 2K. The inner taper 2K tapers from an inner cylindrical surface (i.e., cylindrical surface surrounding the spring 4) towards a housing opening 2H. This opening 2H is sized and configured to receive the end of the rotatable retaining bolt 1. At least two shell-shaped threaded-nut segments 3-1, 3-2 are located in the housing 2. Each of these segments 3-1 and 3-2 have an outer mantle or surface 3-1M, 3-2M which is tapered, i.e., the segments have an external bevel. The taper of the segments 3-1M and 3-2M are sized and configured to fit and/or slidably engage the interior taper 2K.

[0056] The threaded-nut segments 3-1, 3-2, and their outer surfaces 3-1M, 3-2M, move within the interior taper 2K towards and away from the housing opening 2H. Moreover, such axial movement causes the segments 3-1 and 3-2 to correspondingly move towards and away from each other.

[0057] The threaded-nut segments 3-1, 3-2 are pressed or biased towards the housing opening 2H by a spiral pressure spring 4. As a result, the rotatable retaining bolt 1 can be pressed or forced between the movable threaded-nut segments 3-1, 3-2 against the force of the spring 4 in such a way that its external threads 1W locks into the internal threads of the threaded-nut segments 3-1, 3-2. The more forcefully the bolt 1 is pressed between the threaded-nut segments 3-1, 3-2, the more thread-turns of the segments 3-1 and 3-2 lock into the threads 1W of the bolt 1 and vice versa.

[0058] In the lock and/or threaded engagement position, the threads 1W of the rotatable retaining bolt 1 are connected with the threads of the threaded-nut segments 3-1, 3-2. Moreover, by rotating the bolt 1 in one direction, the connection can be made tighter. On the other hand, threading the bolt 1 in an opposite direction, causes the connection to become un-tightened. In this way, the initial “loose” locked connection can be transformed into a secure threaded connection. Additionally, a “locked” or tightened connection can be separated by simply rotating the bolt 1 in an un-tightening direction, i.e., the connection can be detached by unscrewing the bolt 1.

[0059] The spiral spring 4 is located and/or arranged between the floor and/or annular surface 2B of the housing 2 and a disk or washer 5. The washer 5 can move in the direction of the axis of the rotatable retaining bolt 1 and lies against an annular surface of the threaded-nut segments 3-1, 3-2.

[0060] The floor 2B of the housing 2 and the disk or washer 5 each have an opening which is sized and configured to receive and/or guide the rotatable retaining bolt 1 therethrough.

[0061] The housing 2 also includes a circumferential projecting portion or edge 1-R which projects outwardly from the cylindrical housing 2. This edge 1-R may have the form of a flange which includes openings (See e.g., ref. No. 1-R′ FIG. 2) or may be in the form of projecting edge-segments which projecting outwards (not shown).

[0062] The bolt connector is located and/or mounted in a vibration-damping ring 7. The ring 7 can be made of a vibration-damping material. This material is preferably rubber or an elastomer.

[0063] An outer surface or mantle of the vibration-damping ring 7 is connected, e.g., fixedly connected, with the interior surface of an open hollow cylinder 8. This cylinder 8 has a supporting flange or edge 8-1 which extends outwardly. Alternatively, the edge 8-1 may be in the form of outwardly projecting segments.

[0064] The vibration-damping ring 7 and the hollow cylinder 8 can be securely mounted, e.g., fixedly mounted, in the opening HMP2 of the second component MP2.

[0065] In this way, an outer surface of the second component MP2 can contact or lie against the supporting edge 8-1 of the hollow cylinder 8. The edge 8-1 can also be connected to this outer surface in any desired way, e.g., by using an adhesive between the contact surfaces.

[0066] A vibration-damping and/or anti-slip material, which can be in the form of, e.g., a coating, may also be located on an inner surface of the supporting edge 8-1. This material would be sandwiched between the edge 8-1 and the outer surface of the second component MP2.

[0067] A securing ring 6 can be arranged on an inner or upper side of the second component MP2. This ring 6 ensures that the hollow cylinder 8 is secured to the second component MP2 and is arranged near an edge of hole HMP2. Th ring 6 has inwardly pointing spring-loaded tappets which are connected by spring actuation to the hollow cylinder 8, i.e., the tappets frictionally engage an outer circumferential surface of the cylinder 8. Of course, the invention contemplates that other devices can be utilized to securely connect or fix the hollow cylinder 8 to the second component MP2.

[0068] A centering ring 9 is also arranged on the bolt connector. The ring 9 includes a beveled and/or tapered inner edge which is located above the opening 2H. The ring 9 can also be secured to an upper portion of the housing 2. The purpose of the ring 9 is to help align the bolt 1 relative to the axis of the bolt connector.

[0069] The projecting edge 1-R (or the edge segments) extend beyond an internal dimension of the hollow cylinder 8, i.e., the edge 1-R has an outer diameter which is greater than an internal diameter of the cylinder 8. In this way, the lower part, i.e., edge 8-1, of the hollow cylinder 8 acts as a stop for the edge 1-R when the vibration-damping ring 7 is subject to sufficient axial deformation, i.e., deformation sufficient to allow edge 1-R to contact edge 8-1.

[0070] A guide sleeve 10 is used to mount the bolt 1 in the opening HMP1 of the first component MP1. The rotatable retaining bolt 1 is capable of rotating within an opening and the cylindrical wall 10-2 of the guide sleeve 10.

[0071] The guide sleeve 10 has a retaining flange or edge 10-1, which can also be in the form of projecting segments. The flange 10-1 has an inner annular surface which can rest or lie against an outer surface of the first component MP1. Tappets or projecting portions are arranged at an opposite end of the sleeve 10. These projections N are sized and configured to hook over the lower edge of the opening HMP1 of the component MP1.

[0072] The locking/bolting connection arrangement shown in FIG. 1 can also be designed without using a vibration-damping ring 7. In this case, the opening HMP2 would be sized to snugly receive the outer cylindrical surface of the housing 2 and the ring 6 would be sized to frictionally engage this outer cylindrical surface.

[0073] FIG. 2 shows a perspective view of another embodiment of a locking/bolting connector. As with the embodiment of FIG. 1, the bolt connector can receive and/or connect with a threaded bolt. The bolt connecter includes a housing 2′, which is in form of a hollow cylinder, and two internally threaded-nut segments 3-1′ and 3-2′.

[0074] The housing 2′ has a flange or edge 1-R′ which projects outwardly. The flange 1-R′ can also openings FO. As with the embodiment of FIG. 1, this flange 1-R′ can alternatively have the form of outwardly projecting edge segments.

[0075] The outwardly projecting edge 1-R′ is configured to act as an assembly flange 1-R′ and can facilitate attachment to a component, e.g., second component MP2. In this regard, fasteners can be used to fasten the flange 1-R′ to the component using the openings FO. Of course, the flange 1-R′ can also be attached using an adhesive, as was described with regard to FIG. 1. Moreover, the flange 1-R′ can also include the anti-slip or vibration dampening material as in the embodiment shown in FIG. 1.

[0076] As with the embodiment shown in FIG. 1, two threaded-nut segments 3-1′ and 3-2′ are located the interior of the housing 2′. Moreover, as with the embodiment shown in FIG. 1, the bolt connector shown in FIG. 2 can include the spring 4, tapers 3-1M, 3-2M, 2K, floor 2B and washer 5. For reasons of simplification, however, the interior taper and the spiral pressure spring etc. are not shown in FIG. 2.

[0077] FIG. 3 shows a horizontal sectional view of the locking/bolting connector according to FIG. 2 (looking upwards). The designations for the housing, the two threaded-nut segments, the spaces and the stops are the same as in FIG. 2.

[0078] The threaded-nut segments 3-1′, 3-2′ have a space between them, i.e., they are spaced apart. Oppositely arranged stops S1′ and S2′ project from the interior wall of housing 2′ into the spaces D1, D2 which are defined between the threaded-nut segments 3-1′, 3-2′. These stops S1′ and S2′ are sized and configured to limit the axial rotatability of the threaded-nut segments 3-1′, 3-2′.

[0079] The retaining bolt 1 and bolt connector can be of the type that is known in the art. Document EP 03 52 542, the disclosure of which is expressly incorporated by reference in its entirety, illustrates such devices. Moreover, the invention provides an arrangement in which the more forcefully the bolt 1 is pressed into and/or between the threaded-nut segments 3-1, 3-2, the more thread-turns of the segments lock into the threads of the bolt 1. Thereafter, rotating the bolt 1 in the tightening direction causes further tightening of the bolt 1 into the threads of the segments. Rotating the bolt 1 in the opposite direction causes a loosening of the bolt threads within the threaded-nut segments 3-1, 3-2.

[0080] It is noted that the foregoing examples have been provided merely for the purpose of explanation and are in no way to be construed as limiting of the present invention. While the present invention has been described with reference to an exemplary embodiment, it is understood that the words that have been used are words of description and illustration, rather than words of limitation.
