Semi-Rigid Structure: As used in this disclosure, a semi-rigid structure is a solid structure that is stiff but not wholly inflexible and that will deform under force before breaking. A semi-rigid structure may or may not behave with an elastic nature in that a semi-rigid structure need not return to its relaxed shape.
Sinister: As used in this disclosure, sinister is a directional reference that refers to the left side of an object from the perspective of a viewer who is facing the posterior side of the object.
Slot: As used in this disclosure, a slot is a long narrow cut or opening that is formed in or through an object.
Superior: As used in this disclosure, the term superior refers to a directional reference that is parallel to and in the opposite direction of the force of gravity when an object is positioned or used normally.
Supporting Surface: As used in this disclosure, a supporting surface is a horizontal surface upon which an object is placed and to which the load path of the object is transferred. This disclosure assumes that an object placed on the supporting surface is in an orientation that is appropriate for the normal or anticipated use of the object.
Transverse Direction: As used in this disclosure, the transverse direction runs from the anterior surface to the posterior surface of an object and is perpendicular to the coronal direction and the sagittal direction
Transverse Plane: As used in this disclosure, the transverse plane refers to a reference plane that bisects a superior surface and inferior surface such that the transverse plane contains the line of the transverse direction and the line of the transverse direction. The transverse plane is perpendicular to the coronal plane and the sagittal plane.
Truncated: As used in this disclosure, a geometric object is truncated when an apex, vertex, or end is cut off by a line or plane.
Vertical: As used in this disclosure, vertical refers to a direction that is either: 1) perpendicular to the horizontal direction; 2) parallel to the local force of gravity; or, 3) when referring to an individual object the direction from the designated top of the individual object to the designated bottom of the individual object. In cases where the appropriate definition or definitions are not obvious, the second option should be used in interpreting the specification. Unless specifically noted in this disclosure, the vertical direction is always perpendicular to the horizontal direction.
With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention described above and in
It shall be noted that those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the various embodiments of the present invention which will result in an improved invention, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
