Tilting pad assemblies for exercise machines
A tilting pad assembly for exercise machines and the like. A tilting pad assembly may include a pad and a pivot assembly coupled to the pad. The pivot assembly may include a pair of lift bases having contoured indentations disposed therein, the contoured indentations being opposingly facing and spaced apart. A lift support has a first end pivotably coupled to the pad and a second end having a pair of guide pegs extending outwardly into engagement with the contoured indentations such that the second end of the lift support is moveably captured between the pair of lift bases. The contoured indentations provide a first position for the guide pegs wherein the pad is stably supported by the lift support in a lowered position, and provide a second position for the guide pegs wherein the pad is stably supported by the lift support in a raised position.
1 . A pivot assembly configured to pivotably couple a pad to a pad support, the pivot assembly comprising:
a pair of lift bases, each lift base having a contoured indentation disposed therein, the pair of lift bases being configured to be coupled to the pad support such that the contoured indentations are opposingly facing and spaced apart; and
a lift support having a first end configured to be pivotably coupled to the pad and a second end having a pair of guide pegs extending outwardly from the second end in opposing directions and into engagement with the contoured indentations such that the second end of the lift support is moveably captured between the pair of lift bases with the pair of guide pegs moveably disposed within the contoured indentations, wherein the contoured indentations are configured to provide a first position for the guide pegs wherein the pad is stably supported by the lift support in a lowered position and further configured to provide a second position for the guide pegs wherein the pad is stably supported by the lift support in a raised position;
wherein the first end of the lift support is pivotably coupled to the pad by a coupling assembly, the coupling assembly including a tab member coupled to a lower pad surface, and a bale member coupled to the tab member and pivotably coupled to the first end of the lift support; and
wherein the bale member is slideably moveable along a lengthwise portion of the tab member.
2 . The pivot assembly of claim 1 , wherein each lift base includes a flat surface, the contoured indentations being disposed in the flat surfaces.
3 . The pivot assembly of claim 2 , wherein the contoured indentations are opposingly facing and spaced apart by an operational distance that enables the second end of the lift support to move between the flat surfaces as the pair of guide pegs are moved between the first position and the second position.
4 . The pivot assembly of claim 1 , wherein each lift base includes a support portion that is configured to engage with the lower pad surface when the guide pegs are positioned in the first position.
5 . The pivot assembly of claim 1 , wherein the pad is pivotably coupled to the pad support at a pivot base such that the pad is pivotable about the pivot base as the guide pegs are moved within the contoured indentations between the first position and the second position.
6 . The pivot assembly of claim 1 , wherein each contoured indentation is configured to provide a contoured body disposed therein, the contoured body having an upper body surface, the guide pegs being engaged with the upper body surfaces when the guide pegs are in the second position.
7 . The pivot assembly of claim 1 , wherein each contoured indentation has an outer perimeter having a notch formed therein, the guide pegs being engaged with the notches formed in the outer perimeters when the guide pegs are in the first position.
8 . An exercise machine, comprising:
a support frame; and
a tilting pad assembly operatively coupled to the support frame, the tilting pad assembly including at least:
a pad; and
at least one pivot assembly pivotably coupling the pad to a pad support, the at least one pivot assembly including:
a pair of lift bases, each lift base having a contoured indentation disposed therein, the pair of lift bases being coupled to the pad support such that the contoured indentations are opposingly facing and spaced apart; and
a lift support having a first end pivotably coupled to the pad and a second end having a pair of guide pegs extending outwardly from the second end in opposing directions and into engagement with the contoured indentations such that the second end of the lift support is moveably captured between the pair of lift bases with the guide pegs moveably disposed within the contoured indentations, wherein the contoured indentations provide a first position for the guide pegs wherein the pad is stably supported by the lift support in a lowered position and provide a second position for the guide pegs wherein the pad is stably supported by the lift support in a raised position;
wherein the at least one pivot assembly comprises a pair of pivot assemblies.
9 . The exercise machine of claim 8 , further comprising a slidable carriage slidably coupled to the support frame.
