Ladder rack

Claim 2

A ladder rack for a van-type vehicle comprising: a frame adapted to overlie the roof of the vehicle and including a transverse member adapted to at least partially support one or more ladders placed on the frame; means for mounting the frame to the roof of the vehicle; a hook member having a pivot end pivotably attached to the transverse member, an intermediate downwardly concave portion extending outwardly with respect to the vehicle and adapted to project over one of the rails of a ladder placed on said frame when the hook member is pivoted downwardly about said pivot end, and an opposite free end adapted to project downwardly between the rails of said ladder when said hook member is pivoted downwardly; a lever pivotably attached to an end of said transverse member; a rod generally parallel to the transverse member and having one end connected to the lever proximate said end of the transverse member and another end slidably connected to the pivot end of the hook member; a spring having one end connected to the hook member and another end connected to the rod so that pivoting of said lever in one direction moves the hook member from a release position to a ladder holding position and further movement of said lever in said one direction compresses the spring against the hook member to bias the hook member against the ladder; and means for locking the pivot means in the ladder holding position comprising means for maintaining the lever in an over center position with the hook member biased against the rail of the ladder.

Claim 3

A ladder rack for a van-type vehicle comprising: a frame adapted to overlie the roof of the vehicle and including fore and aft transverse members adapted to support one or more ladders placed thereon; means for mounting the frame to the roof of the vehicle; a hook member having a pivot and pivotably attached to one of the transverse members, an intermediate downwardly concave portion extending outwardly with respect to the vehicle and adapted to project over one of the rails of a ladder placed on said frame when the hook member is pivoted downwardly about said pivot end, and an opposite free end adapted to project downwardly between the rails of said ladder when said hook member is pivoted downwardly; a lever pivotably attached to an end of said one transverse member; a rod generally parallel to the transverse member having one end connected to the lever proximate said end of the transverse member and another end slidably connected to the pivot end of the hook member; and a spring circumscribing the rod and having one end connected to the hook member and another end connected to the rod so that pivoting of said lever in one direction pivots the hook member downwardly from an upwardly raised release position to a ladder holding position with the intermediate portion of the hook member against one of the rails of a ladder placed on the frame, and further movement of said lever in said one direction compresses the spring against the hook member to bias the intermediate portion of the hook member against the ladder.

Claim 4

A ladder rack for a van-type vehicle comprising: a frame adapted to overlie the roof of the vehicle and including fore and aft transverse members adapted to support one or more ladders placed thereon; means for mounting the frame to the roof of the vehicle; a hook member having a pivot and pivotably attached to one of the transverse members, an intermediate downwardly concave portion extending outwardly with respect to the vehicle and adapted to project over one of the rails of a ladder placed on said frame when the hook member is pivoted downwardly about said pivot end, and an opposite free end adapted to project downwardly between the rails of said ladder when said hook member is pivoted downwardly; a lever pivotably attached to an end of said one transverse member; a rod generally parallel to the transverse member having one end connected to the lever proximate said end of the transverse member and another end slidably connected to the pivot end of the hook member; and a spring circumscribing the rod and having one end connected to the hook member and another end connected to the rod so that pivoting of said lever in one direction pivots the hook member downwardly from an upwardly raised release position to a ladder holding position with the intermediate portion of the hook member against one of the rails of a ladder placed on the frame, and further movement of said lever in said one direction compresses the spring against the hook member to bias the intermediate portion of the hook member against the ladder.

Claim 5

A ladder rack as recited in claim 2 wherein said lever is movable in said one direction to an over center position, and additionally comprising means for maintaining said lever in said over center position to lock the hook member in the ladder holding position.

Claim 6

A ladder rack as recited in claim 3 wherein said one end of the transverse member includes a flat plate having a projection, and wherein the portion of the lever attached to said one end of the transverse member includes a planar portion overlying the plate and having a detent adapted to engage the projection in the plate when the lever is moved to the over center position.

Claim 7

A ladder rack for a van-type vehicle comprising: a frame adapted to overlie the roof of the vehicle and including fore and aft transverse members adapted to support a pair of ladders in a side-by-side relationship; means for mounting the frame to the roof of the vehicle; a pair of hook members each having a pivot end pivotably attached to one of the transverse members intermediate the positions of the two ladders, said hook members each including an intermediate downwardly concave portion adapted to project outwardly over the inside rails of the respective ladders when the hook members are pivoted downwardly about their pivot ends, and an opposite free end adapted to project downwardly between the rails of the respective ladders when the hook members are pivoted downwardly; and means for actuating each of the hook members, said actuating means each comprising a lever pivotably attached to an end of said one transverse member, a rod generally parallel to the transverse member and having one end connected to the lever proximate said end of the transverse member and another end slidably connected to the pivot end of the hook member, a spring having one end connected to the hook member and another end connected to the rod, and means for maintaining the lever in an over center position so that movement of the lever in one direction toward the over center position pivots the associated hook member downwardly from an upwardly raised release position to a ladder holding position with the intermediate portion of the hook member against one of the rails of the associated ladder and further movement of the lever in said one direction to the over center position compresses the spring against the hook member to bias and lock the intemediate portion of the hook member against the ladder.

Claim 8

A ladder rack for a van-type vehicle comprising: a frame adapted to overlie the roof of the vehicle and including fore and aft transverse members adapted to support a pair of ladders in a side-by-side relationship; means for mounting the frame to the roof of the vehicle; a pair of hook members each having a pivot end pivotably attached to one of the transverse members intermediate the positions of the two ladders, said hook members each including an intermediate downwardly concave portion adapted to project outwardly over the inside rails of the respective ladders when the hook members are pivoted downwardly about their pivot ends, and an opposite free end adapted to project downwardly between the rails of the respective ladders when the hook members are pivoted downwardly; and means for actuating each of the hook members, said actuating means each comprising a lever pivotably attached to an end of said one transverse member, a rod generally parallel to the transverse member and having one end connected to the lever proximate said end of the transverse member and another end slidably connected to the pivot end of the hook member, a spring having one end connected to the hook member and another end connected to the rod, and means for maintaining the lever in an over center position so that movement of the lever in one direction toward the over center position pivots the associated hook member downwardly from an upwardly raised release position to a ladder holding position with the intermediate portion of the hook member against one of the rails of the associated ladder and further movement of the lever in said one direction to the over center position compresses the spring against the hook member to bias and lock the intemediate portion of the hook member against the ladder.
