Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
151 words
An entrance step apparatus adapted to be connected between a stationary portion and a movable portion of an entrance area such as the movable door structure on a vehicle, comprising: a. a support assembly securable to the stationary portion and including a member when mounted extended substantially laterally therefrom, said member having bearing means mounted in an outer end portion thereof; b. a step assembly having one end portion thereof pivotally connected to said bearing means for movement about a substantially vertical axis; and c. an actuator assembly having a positioning arm member operably connectable in one end portion to the movable portion and pivotally connected to the step assembly in the other end portion of said step assembly whereby on movement of said movable portion with said entrance apparatus connected said step assembly is pivoted about said bearing means from a concealed position to an extended, revealed position for usage.
Claim 2
Dependent Claim
151 words
An entrance step apparatus adapted to be connected between a stationary portion and a movable portion of an entrance area such as the movable door structure on a vehicle, comprising: a. a support assembly securable to the stationary portion and including a member when mounted extended substantially laterally therefrom, said member having bearing means mounted in an outer end portion thereof; b. a step assembly having one end portion thereof pivotally connected to said bearing means for movement about a substantially vertical axis; and c. an actuator assembly having a positioning arm member operably connectable in one end portion to the movable portion and pivotally connected to the step assembly in the other end portion of said step assembly whereby on movement of said movable portion with said entrance apparatus connected said step assembly is pivoted about said bearing means from a concealed position to an extended, revealed position for usage.
Claim 3
Dependent Claim
98 words
An entrance step apparatus as described in claim 1, wherein: a. said step assembly including a horizontally extended main body of generally rectangular shape having laterally extended connector tab pivotally connected by a bolt member to one end of said positioning arm member; and b. said actuator assembly including an anchor plate member secured to the movable portion and having a laterally extended connector tab member pivotally connected to the opposite end of said positioning arm whereby said positioning arm member operates to pivotally move said step assembly about said bearing assembly on moving of the movable portion.
Claim 4
Dependent Claim
73 words
An entrance step apparatus as described in claim 2, wherein said positioning arm member extended in a substantially common vertical plane and having opposed end sections extended in spaced, parallel planes, said positioning arm member having a midportion extended downwardly from said anchor plate to said connector tab on main body whereby said step assembly may be concealed vertically underneath the movable portion but extended outwardly therefrom when moved to the usage condition.
