The following detailed description is, therefore, not to be taken in a limiting sense.

[0046] Throughout the specification and claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise. The term “herein” refers to the specification, claims, and drawings associated with the current application. The phrase “in an embodiment” as used herein does not necessarily refer to the same embodiment, though it can.

Thus, as described below, various embodiments can be readily combined, without departing from the scope or spirit of the invention.

[0047] In addition, as used herein, the term “or” is an inclusive “or” operator, and is equivalent to the term “and/or,” unless the context clearly dictates otherwise. The term “based on” is not exclusive and allows for being based on additional factors not described, unless the context clearly dictates otherwise. In addition, throughout the specification, the meaning of “a,” “an,” and “the” include plural references. The meaning of “in” includes “in” and “on.”

[0048] FIGS. 1A and 1B schematically show a device 1 for stabilizing movements of two bodies of a body joint and/or of an item of sporting equipment that can be moved relative to one another. The device 1 comprises a receptacle 20, which is filled with a filling medium 30. An interaction body 40 extends at least partially into a receiving space 24 of the receptacle 20. The device may be arranged between two bodies which can be moved relative to one another in such a way that the receptacle 20 is connected to a first body and the interaction body 40 is connected to a second body, with the result that a force flow can be defined between the two bodies which can be moved relative to one another by way of the device 1.

[0049] In the event of loading, i.e. when a force acts on the device starting from two bodies to be stabilized which are not part of the device, the interaction body 40 and the receptacle 20 can be moved relative to one another in a relative movement direction R.

[0050] The receptacle 20 has a receiving opening 22, through which the receptacle 20 can be filled with the filling medium 30. In addition, the interaction body 40 extends at least partially through the receiving opening 22, with the result that part of the interaction body 40 can always be located in the receiving space 24 and another part of the interaction body 40 can always be located outside the receptacle 20.

[0051] In the region of the receiving opening 22, the device 1 has a first connection element 50 for connection to a body which is not part of the device. The first connection element 50 extends perpendicularly to a longitudinal axis L of the device 1. As can be seen in FIGS. 1A and 1B, the first connection element 50 extends symmetrically from the longitudinal axis L of the device 1 and forms two connection projections or connection surfaces.

[0052] The first connection element 50 serves as an interface for the transfer of force between a first body which is not part of the device and the device 1. Arranged on the exposed part of the interaction body 40 is a second connection element 60 that serves as an interface for the transfer of force between a second body which is not part of the device and the device 1. Consequently, a force path is produced between the first connection element 50, the operative medium 30, the interaction body 40 and the second connection element 60 in the event of loading.

[0053] The arrangement of the first connection element 50 in the region of the receiving opening 22 makes it possible for the outer walls of the receptacle 20 to be largely relieved of load. For the unipartite configuration of connection element 50 and receptacle 20 shown in FIGS. 1A and 1B, this means that the receptacle 20 can have a comparatively thin-walled design, since a force flow through the device 1 is not directly tangent to the receptacle 20 in the event of loading.

[0054] In another embodiment, in which the first connection element and the receptacle are designed in two parts, the arrangement of the first connection element in the region of the receiving opening provides the advantage that an external force cannot have an adverse effect on the link between the first connection element and the receptacle.

[0055] As shown in FIG. 1B, the first connection element 50 defines the receiving opening 22. In order to ensure that the operative medium 30 can be held in the receiving space 24 in a usage situation, the receptacle 20 has an O-ring 26 in the region of the receiving opening 22.

[0056] The filling medium 30 is a Newtonian fluid, such as silicone oil. As an alternative, dilatant fluids may also be used. In addition, the filling medium may also be provided in the form of a shear-thickening plastic in powder form. Furthermore, filling materials such as sand, for example, may also be used.

[0057] FIGS. 1C and 1D show further configurations of the device 1, which differ from the device shown in FIGS. 1A and 1B in terms of the design of the first connection element. The device 1 according to FIG. 1C has a first connection element 50, which is formed integrally with the receptacle 20 and comprises a cylindrical portion which provides a comparatively large connection surface 51.

[0058] The device 1 according to FIG. 1D exhibits an annular connection element 50 that is adhesively bonded to the receptacle 20 and provides a comparatively large connection surface 51.

[0059] FIG. 2A schematically shows a side view of a further embodiment of the device 1. FIG. 2B shows a sectional view of the device 1 from FIG. 2A. FIGS. 2A and 2B show a first connection element 50 that has a geometry which is changed with respect to the first connection element according to FIGS. 1A and 1B.

[0060] According to FIGS. 2A and 2B, the first connection element 50 has two connection portions 54, which extend in a symmetrical manner perpendicularly from the longitudinal axis L of the device 1. Support arms 56 extend from an outer end 55 of the connection portions 54 substantially parallel to the longitudinal axis L of the device 1 along the receptacle 20. The ends of the support arms 56 each define a second outer end 57, which is configured to be supported on the receptacle 20 when a force acts on the first connection element 50. As a result of it being possible for the first connection element 50 to be supported on the receptacle 20 via the support arms 56, the first connection element 50 according to FIGS. 2A and 2B is able to transfer larger forces than the device shown in FIGS. 1A and 1B for this purpose.

[0061] In order to provide the supporting function, the first connection element 50 and in particular the support arms 56 have a flexible form. In a preferred material pairing, the receptacle 20 is manufactured from aluminum and the first connection element 50 is manufactured from plastic.

[0062] According to FIGS. 2A and 2B, the first connection element 50 and the receptacle 20 are designed in two parts. This provides the advantage that an external force cannot have an adverse effect on the link between the first connection element 50 and the receptacle 20. Forces starting from the interaction body 40 act on the filling medium 30 in the event of loading, said filling medium transferring the force in turn to the first connection element 50, which is arranged in the receiving opening 22. The force can then be transferred from the first connection element 50 to a body which is not part of the device.

[0063] In this respect, the force acting between the body which is not part of the device and the first connection element 50 ensures that the first connection element 50 is pressed into the receiving opening 22.

[0064] The first connection element 50 may be connected to the receptacle 20 in an adhesively bonded, welded, interference-fitting and/or form-fitting manner.

[0065] FIG. 3A shows a side view of a device 1 which comprises a first connection element 50 having two wing bodies 52, which extend perpendicularly from a longitudinal axis L of the device 1 and lie in a plane defined by the longitudinal axis L. The wing bodies 52 serve to increase the connection surface area for connection to a body which is not part of the device. The wing bodies 52 increase the surface area of the first connection element 50 and provide an additional surface as a result, which can be adhesively bonded or enclosed in a bandage in order to fasten the first connection element 50 to a first body which is not part of the device.

[0066] The first connection element 50 may be formed in one piece with the wing bodies 52. As an alternative, the first connection element 50 and the wing bodies 52 may also be designed separately. For example, the first connection element 50 may be provided, as shown in FIGS. 1A and 1B. A wing body has a negative imprint of the first connection element and part of the receptacle and may be connected to the first connection element in a form-fitting manner, for example by way of a clip link. As an alternative, the first connection element and the wing bodies may be adhesively bonded, welded or interference fitted.

[0067] FIG. 3A shows an additional wing body 53, which is arranged on an end portion of the receptacle 20. The wing body 53 makes it possible to provide an additional connection surface for the receptacle 20 to a body which is not part of the device. The connection surfaces of the wing bodies 52 and 53 are suitable for integration in textiles or for fastening to a body which is not part of the device with bandages, tapes, etc. In this respect, the connection surfaces of the wing bodies 52 and 53 may be adhesively bonded, welded, riveted, sewed etc. to a textile element.

[0068] FIG. 3B shows the section A-A from FIG. 3A. The wing body 52 is clipped on the connection body 50 by means of an interference fit. Apart from an interference fit, the wing body and the connection body may also be adhesively bonded, welded etc. As an alternative, the wing body and the connection body may also have a unipartite design.

[0069] FIG. 4 shows a side view of the device 1 from FIG. 3, the wing bodies 52, 53 being enclosed by an attachment 70. In this respect, the attachment 70 forms a loop 72, which serves as an interface for the transfer of force between the first connection element 50 and the attachment 70. In addition to the transfer of force between the device 1 and a first body, the attachment 70 serves to keep the receptacle 20 in position by means of the wing bodies 52, 53. Consequently, the receptacle 20 may be held in abutment against a first body, for example.

[0070] FIG. 5 shows a side view of the device 1 from FIG. 1A, the first connection element 50 being enclosed by the attachment 70. In this respect, the attachment 70 forms a loop 72, which acts as an interface for the transfer of force between the first connection element 50 and the attachment 70.

[0071] The attachment shown in FIGS. 4 and 5 may be designed in the form of a textile loop or pocket, by means of which the first connection element or the first connection element including the receptacle 20 can be held and fastened to a first body by adhesive bonding, sewing, riveting, welding etc.

[0072] FIG. 6A shows a side view of a device 1 according to FIG. 2A, the device being arranged in an attachment 70 in the form of a pocket 74. FIG. 6B shows a plan view of the device according to FIG. 6A. The partial arrangement of the device 1 in the pocket 74 is illustrated by dashed lines. The pocket 74 is formed from a textile and accommodates the first connection element 50 and the receptacle 20. The pocket 74 may be fastened to the first body which is not part of the device by adhesive bonding, sewing, riveting, welding etc. As an alternative, the pocket 74 may also be integrated in the first body which is not part of the device.

[0073] If applicable, all individual features illustrated in the exemplary embodiments may be combined with one another and/or interchanged with one another without departing from the scope of the disclosure.
