Low profile ladder rack
View Patent ↗A ladder rack for a motor vehicle similar to what is shown in U.S. Pat. No. 6,764,268, but differing therefrom in that the top surfaces of the stationary bar member and the movable bar member are coplanar and in a side-by-side relationship when the load being carried is atop the vehicle's roof rather than being stacked, one-above-the-other, as in the prior art. As such, the ladder rack of the present invention exhibits a reduced height profile.
1. Apparatus for facilitating the loading and unloading of a ladder from the roof of a motor vehicle, comprising in combination:
a) a first and a second 4-bar linkage assembly, each including a stationary bar member adapted to be attached to the roof of a motor vehicle in parallel, spaced-apart relation so as to extend transverse to the longitudinal axis of said motor vehicle and a movable bar member comprising a ladder support pivotally coupled to and offset from the stationary bar member by a pair of rigid links arranged such that rotation of one of said pair of rigid links on each of the first and second 4-bar linkage assemblies results in said movable bar member comprising said ladder support moving between a first disposition where a top surface of the movable bar member is in coplanar relation with a top surface of the stationary bar member to a second disposition aligned and spaced from one side of the vehicle;
b) a connecting rod extending longitudinally between the first and second 4-bar linkage assemblies with the connecting rod journaled for rotation in the stationary bar members of each of the 4-bar linkage assemblies and operatively coupled to one of said pair of rigid links in each of the 4-bar linkage assemblies; and
c) mean for rotating said connecting rod.
2. The apparatus as in claim 1 and further including a shock absorber operatively coupled between the stationary bar member of at least one of the first and second 4-bar linkage assemblies and the connecting rod, the shock absorber positioned so as not to extend above the top surface of the stationary bar member to which it is attached.
3. The apparatus as in claim 1 wherein the means for rotating comprises a lever for applying a torque to the connecting rod.
4. The apparatus as in claim 1 and further including an elastomeric, non-scratch covering on the top surface of both the stationary bar and the movable bar.
5. The apparatus as in claim 1 wherein the individual ones of the pair of linkages pivotally join to the movable bar on opposite side surfaces thereof such that one of said pair of linkages lies between the movable bar and the stationary bar when the top surfaces of the movable bar and the stationary bar are in coplanar relationship.
6. The apparatus as in claim 4 and further including a pair of supports extending laterally from one side of the stationary bar member upon which the movable bar members rest when atop the vehicle's roof.
