Description

FIELD OF THE INVENTION

This invention relates generally to caskets, and more particularly to shipping caskets.

BACKGROUND OF THE INVENTION

It is known to ship caskets in box trucks and in trailers of tractor-trailer rigs. Box trucks are typically used to deliver caskets to funeral homes, whereas tractor-trailer rigs are typically used to deliver caskets to warehouse distribution facilities.

When shipping caskets in a box truck, the caskets are typically loaded horizontally and placed on shelves. During delivery the caskets are pushed/pulled from the shelves onto a lift system that allows the casket to be lowered and placed upon a rolling and vertically extendible/retractable cart known as a “church truck.” The church truck is supported on the pavement the same as the box truck. Consequently, the surface of the bed of the box truck can be several feet above the surface of the pavement.

When shipping caskets in trailers of tractor-trailer rigs, the caskets are typically loaded vertically, or “on end.” Loading the caskets vertically allows more caskets to be hauled in a given size trailer than if the caskets were loaded horizontally, which is of course desirable. Caskets transported in trailers of tractor-trailer rigs are typically unloaded at a loading dock. The surface of the loading dock is generally at the same height as the surface of the bed of the trailer, i.e. the surfaces are generally co-planar. The caskets are unloaded at docks with the use of a four wheeled device known as a “tip cart.” The tip cart has a base frame with four wheels, and a tip frame pivoted to one end of the base frame that pivots from horizontal to vertical. To unload a casket with the tip cart, the vertically oriented casket is moved to the edge of the trailer bed. The tip cart is rolled to the edge of the dock. The tip frame is manually pivoted from horizontal to vertical, the casket is secured to the tip frame, and the tip frame with casket secured thereto is manually pivoted from vertical to horizontal. The casket is then rolled on the tip cart. These devices allow the caskets to be safely moved out of trailers without damaging the caskets.

Previous attempts at utilizing vertical shipping of caskets in box trucks have not met with success. This is primarily due to the bed of the box truck being several feet above the surface of the pavement, which increases the risk of damage to the caskets and the safety risks to personnel during unloading of the caskets.

Accordingly, a casket loading and/or unloading apparatus and method which allows personnel to safely unload vertical caskets from a box truck without damaging the caskets is desirable.

For that matter, a casket loading and/or unloading apparatus and method which allows personnel to safely unload vertical caskets from any transport vehicle, where the surface of the bed of the vehicle is above the surface to which the casket is being unloaded to, without damaging the caskets, is also desirable. Such a transport vehicle could be the aforementioned box truck, but it could also be a trailer of a tractor-trailer rig, etc.

SUMMARY OF THE INVENTION

In one aspect, a casket loading and/or unloading apparatus comprises a frame having an end adapted to be pivoted adjacent a rear edge of a bed of a transport vehicle for pivoting about a pivot axis generally transverse to a longitudinal axis of the transport vehicle, and a motion generating device operable between the frame and the transport vehicle for pivoting the frame from a first generally vertical position to a second at least generally horizontal position. A vertically oriented casket in the transport vehicle can be secured to the frame, and the frame with the casket secured thereto can be pivoted from the first generally vertical position to the second at least generally horizontal position to facilitate unloading the casket from the transport vehicle.

The second position can be beyond horizontal. The transport vehicle can be a box truck. The motion generating device can be a hydraulic piston and cylinder. The apparatus can further include a plate removably attached to the end of the frame, oriented generally perpendicularly to the frame, and projecting forwardly from the frame when the frame is in the first generally vertical position, the plate adapted to support an end wall of the vertically oriented casket. The apparatus can further include lubricious material on the frame to facilitate sliding of the casket on the frame.

In another aspect, a combination transport vehicle and casket loading and/or unloading apparatus comprises a transport vehicle bed with a rear edge, a frame having an end pivoted adjacent the rear edge of the bed for pivoting about a pivot axis generally transverse to a longitudinal axis of the transport vehicle, and a motion generating device operable between the frame and the transport vehicle for pivoting the frame from a first generally vertical position to a second at least generally horizontal position. A vertically oriented casket in the transport vehicle can be secured to the frame, and the frame with the casket secured thereto can be pivoted from the first generally vertical position to the second at least generally horizontal position to facilitate unloading the casket from the transport vehicle.

In another aspect, a method of unloading a vertically oriented casket from a transport vehicle comprises securing the vertically oriented casket to a frame having an end pivoted adjacent a rear edge of a bed of the vehicle, positioning a cart aft of the rear edge of the bed, pivoting the frame and casket from a first generally vertical position to a second at least generally horizontal position until an aft end of the casket contacts an aft end of the cart, and further pivoting the frame and casket until a forward end of the casket contacts a forward end of the cart.

The second position can be beyond horizontal. The method can further include sliding the casket off of the frame and/or moving the cart away from the frame.

In another aspect, a method of unloading a vertically oriented casket from a transport vehicle comprises securing the vertically oriented casket to a frame having an end pivoted adjacent a rear edge of a bed of the vehicle, positioning a cart aft of the rear edge of the bed, pivoting the frame and casket from a first generally vertical position to a second at least generally horizontal position until an aft end of the casket contacts an aft end of the cart, and additionally performing at least one of the following steps: (a) further pivoting the frame and casket until a forward end of the casket contacts a forward end of the cart, (b) sliding the casket off of the frame, (c) moving the cart away from the frame.

All three of the steps (a), (b), and (c) can additionally be performed.

In another aspect, a method of unloading a vertically oriented casket from a transport vehicle comprises securing the vertically oriented casket to a frame having an end pivoted adjacent a rear edge of a bed of the vehicle, positioning a cart aft of the rear edge of the bed, pivoting the frame and casket from a first generally vertical position to a second position beyond horizontal, sliding the casket rearwardly until an aft end of the casket contacts an aft end of the cart, and further pivoting the frame and casket until a forward end of the casket contacts a forward end of the cart.

The cart can be rolled rearwardly during the step of further pivoting the frame and casket. The transport vehicle can be a box truck.

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the summary of the invention given above, and the detailed description of the drawings given below, serve to explain the principles of the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective view of an end of a box truck including the apparatus of the present invention.

FIG. 2 is an enlarged perspective view of the end of the box truck of FIG. 1.

FIGS. 3A-3D illustrate the steps in unloading a vertical casket from a box truck with the apparatus of FIGS. 1 and 2.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring first to FIGS. 1 and 2, a transport vehicle, for example box truck 10, with a bed 12 is illustrated with a casket loading and/or unloading apparatus 14 mounted thereto. The apparatus 14 could as well be mounted to a trailer.

The apparatus 14 has a frame 20 having longitudinal frame members 22, 24, 26, 28, and 30, interconnected by transverse frame members 40, 42, 44, 46, 48, and 50. A pair of laterally positioned plates 60, 62 are attached to frame members 22, 30, respectively, and maintain a casket (phantom, FIG. 1) positioned laterally on the frame 20. At least some of the frame members have attached thereto a lubricious, i.e. low coefficient of sliding friction, material, such as plastic strips, to aid in sliding a casket off of the frame 20.

Frame 20 has an end 70 pivoted adjacent a rear edge 72 of bed 12 at pivots 74, 76. A motion generating device, for example hydraulic piston and cylinder 78, is attached to the frame 20 at 80 and to the box truck 10 at 82 and pivots the frame 20 from a first generally vertical position (FIG. 1) to a second at least generally horizontally position (FIG. 2). Preferably the second position is beyond horizontal, for example an angle of between about 90 degrees and about 180 degrees from vertical, and more preferably about 125 degrees (FIG. 3D). Other motion generating devices could be used, for example a cable/winch system, etc.

Referring to FIG. 2, a support plate 90 is removably attached to frame member 50 via pins 92, 94 passing through holes 96, 98 in frame member 50. Locking pins 100, 102 pass through holes (not shown) in the pins 92, 94 to removably secure the support plate 90 to the frame member 50. Support plate 90 supports an end wall of a vertically oriented casket (FIG. 1), not unlike that of a dolly. The support plate 90 can, however, be removed to allow a horizontally loaded casket to be unloaded with the apparatus 14.

Referring now to FIGS. 3A-3D, use of the apparatus 14 will be described. A vertically oriented casket 110 (phantom), is positioned against frame 20 of apparatus 14 and atop support plate 90 with frame 20 being in a generally vertical position. The casket 110 is secured to the frame with, for example, a ratchet strap 112. A wheeled cart 114, for example church truck or the like, is positioned aft of the rear edge 72 of the bed 12 of the box truck 10. The frame 20 is pivoted via the hydraulic piston and cylinder 78 until the aft end 116 of the casket 110 contacts the aft end 118 of the cart 114. The frame 20 is further pivoted via the hydraulic piston and cylinder 78 until the forward end 120 of the casket 110 contacts the forward end 122 of the cart 114. The casket 110 can be slid off the frame 20 and/or the cart 114 can be moved away from the frame 20 to completely remove the casket 110 from the box truck 10.

Preferably, the frame 20 and casket 110 are pivoted from a first generally vertical position to a second position beyond horizontal. Then the casket 110 is slid rearwardly until the aft end 116 of the casket 110 contacts an aft end 118 of the cart 114. Then, the frame 20 and casket 110 are further pivoted until a forward end 120 of the casket 110 contacts a forward end 122 of the cart 114. The cart 114 can either be rolled rearwardly during further pivoting of the frame 20 and casket 110 prior to the forward end 120 of the casket 110 contacting the forward end 122 of the cart 114, or after pivoting of the frame 20 and casket 110 and after the forward end 120 of the casket 110 contacts the forward end 122 of the cart 114.
