The apparatus comprises a frame provided with pneumatic devices for griping a sheet or plate at least two chains for the support of the frame and cooperating with means apt to case the suspended sheet or plate to be rotated, said chains being supported, through a support telescopic device of an adjustable length, by a truck traveling along the rail beams of the overhead traveling crane.

Lautenschlager, EP0580075, describes an automatic telescopic device for drawer runners, comprising a guide rail formed by a profile section turned over from sheet metal to be secured to the carcass wall, said guide rail having a profiled flange bent upwardly from a profiled flange projecting substantially at right angles and horizontally from the carcass wall and engaging from below the associated runner formed by a hollow profile section open at its underside to be removably secured to the drawer, and provided in the interior of the runner with raceways for rolling elements which are held in an elongated cage and can roll, on the one hand, on the raceways of the guide rail and, on the other hand, on raceways formed by associated regions of the inner surface of the runner, thereby allowing for longitudinal displacement of the runner relative to the guide rail, a component which can pivot between two end positions and is biased bistably into the end positions by means of spring arrangement being provided and having an open-ended recess for a projection projecting downwardly from the runner in a portion projecting beyond the horizontal profiled flange of the guide rail into the interior of the carcass, and the projection and the pivoting component being arranged relative to one another in relation to the runner or the guide rail in such a manner that, when the runner is displaced from the open-drawer position, as it approaches the closed position, the projection moves into the recess in the pivoting component in the end position associated with the open-drawer position and then, once the dead center of the pivoting component has been passed, is driven resiliently together with the latter into the closed-drawer position, characterised in that the pivoting component is mounted in a separate elongated housing secured to the guide rail so as to pivot about a substantially perpendicular axis and that a detent is provided immediately in front of the recess in the pivoting component as viewed in the direction of insertion of the drawer, wherein said detent is withdrawn into the housing into the path of the projection projecting from the runner in the end position associated with the open-drawer position, and in the end position associated with the closed-drawer position projects into the path of the projection, but can be traversed by the projection in the direction of insertion by means of resilient deformation.

Lechevallier, EP0691911 describes a removable frame for loading, unloading and moving container's of goods on trucks or wagons without typical lifting machinery such as cranes, gantries and such. It permits unload directly onto the ground. The invention is characterized by arrangement of a frame encompassing the load. Two lifting surfaces are provided with lateral spacing between them and are placed transverse of the vehicle's axle. Each of the surfaces is lifted by a telescoping jack and facility for locking the load in place is provided.

The prior art teaches a very wide range of materials storage and handling systems. However, the prior art does not teach that an actuated clamping device may be mounted onto a truck for clamping panel goods for transport. The present invention fulfills these needs and provides further related advantages as described in the following summary.

SUMMARY OF THE INVENTION

The present invention teaches certain benefits in construction and use which give rise to the objectives described below.

The present invention provides an apparatus for carrying panel materials adjacent to a truck side panel and comprises a stationary workpiece resting surface mounted on the truck side panel and a movable workpiece clamping and supporting device positioned adjacent to the stationary workpiece resting surface and mounted to the truck. A motive device such as a motor engages the truck and is connected for moving the workpiece clamping and supporting device toward and away from the workpiece resting surface for sandwiching a workpiece between the workpiece resting surface and the workpiece clamping and supporting device for enabling the truck to transport the workpiece.

A primary objective of the present invention is to provide a panel carrying device having advantages not taught by the prior art.

Another objective is to provide such a device that is mounted to a truck body and holds the panel for transport.

A further objective is to provide such a panel carrying device that is able to open to accept a load and to close to clamp the load on a truck.

Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION

The above described drawing FIGS. 1-5 illustrates the invention, an apparatus for carrying panel materials such as gypsum wallboard or plywood sheets adjacent to a truck side panel 5 . The apparatus mounts onto the truck side panel 5 and secures one or more sheets or panels which constitute the workpiece 7 for transport.

The apparatus comprises a stationary workpiece resting means 10 enabled by flanges 12 and standard hardware 14 for mounting on the truck side panel 5 . A movable workpiece clamping and supporting means 20 is positioned adjacent to the stationary workpiece resting means 10 and is enabled, as will be discussed in detail below, for mounting to a truck 30 supporting the previously mentioned side panel 5 . A motive means 40 , such as one or more electric motors, engages with the truck 30 and enables moving the workpiece clamping and supporting means 20 toward and away from the workpiece resting means 10 for sandwiching the workpiece 7 between the workpiece resting means 10 and the workpiece clamping and supporting means 20 for enabling the truck 30 to transport the workpiece 7 .

A pair of lateral restraining means 50 , such as the U-shaped bars shown in the figures are attached to the truck side panel 5 , in the same manner as for the workpiece resting means in positions for restraining movement of the workpiece 7 which has a tendency, when mounted as shown, to move forward during braking of the truck 30 , and for moving rearward during acceleration of the truck 30 .

Preferably, the stationary workpiece resting means 10 is a pair of horizontally positioned bars as best seen in FIG. 1 .

Inventively, the movable workpiece clamping and supporting means 20 is adapted for telescopic movement toward and away from the stationary workpiece resting means 10 as best seen in FIGS. 2-5 .

Inventively, the motive means 40 is a screw drive means, such as a linear motor or linear screw driven actuator as is well known in the art, and is mounted to the underchassis of the truck and engaged with the movable workpiece clamping and supporting means 20 for linear motion thereof as is best shown in FIGS. 4 and 5 .

While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims.
