Abstract: A coupling member for coupling modules with each other. The coupling member comprises a coupling portion, which in turn has a coupling rim and at least two hook members disposed on the coupling rim. The coupling portion substantially corresponds in its outer contour to a spherical segment of a sphere with a predetermined spherical radius, wherein the coupling rim represents a circular disk of the spherical segment. In this case, an outer radius of the coupling rim is smaller than or equal to the spherical radius. The at least two hook members, in a lateral view, at least partially follow the outer contour of the spherical cap of the spherical segment. The at least two hook members are engageable with the hook members of a coupling portion of a second coupling member.

Abstract: A coupling device for coupling modules with each other, comprising: a coupling surface, a primary coupling member and at least two secondary coupling members. The primary coupling member is disposed on the coupling surface. A coupling axis disposed parallel to a direction of action of earth's gravitational acceleration extends through the primary coupling member. The at least two secondary coupling members are configured to be complementary to each other and are disposed on the coupling face, and respectively have a predetermined distance from the coupling axis.

Abstract: The present invention describes a method of customizing the saddle to fit the back of a particular horse by using shims of various shapes and sizes between the underside of the saddle and pad. These shims are attached to the underside of the saddle and to the pad by a hook and loop fastening system. Different types molding or rebounding pads may be used. The rebounding pads are useful to allow the interchange of saddles between different horses while achieving a perfect fit on each horse.
