BACKGROUND OF THE INVENTION
The present invention relates generally to glass pane (i.e., plate glass) transport racks. More particularly, this invention pertains to adjustable glass pane transport racks operable to hold or support a plurality of glass pane sizes.
Glass panes (i.e., glass sheets or plates) are transported and stored in a substantially upright and inclined position on a rack. Stacks of glass sheets are secured to the rack with a rope or ratchet straps extending around the glass sheets or over the glass sheets. If the glass sheets are not properly secured to the rack by the rope or ratchet strap, the glass sheets may shift or fall from the rack. Further, if any of the glass sheets shift relative to one another, imperfections on the surface (e.g., digs or scratches) make the glass of inferior quality and often unusable.
Racks for transporting glass sheets are generally application specific. That is, a rack is generally sized to hold a specific size of glass sheet. If a rack made for one size of glass sheet is used with another sizable glass sheet, the glass sheets may slide on the rack, fall from the rack, or break on the rack. Further, when the size of the glass sheet does not match the size of the rack, it may not be possible to secure the glass sheet to the rack.

In one embodiment, the dual sided frame has a width of approximately 7 feet, and a height of approximately 9 feet.
The first knee brace 104 is operable to adjustably extend from a first longitudinal end 116 of the dual sided frame 102. The first knee brace 104 has a first face 118 coincident with a plane of the first face 106 of the dual sided frame 102. The first face 106 provides a substantially flat surface for a glass sheet to lay against when supported by the rack 100. The flat surface of the first face 106 defines the plane of the first face 106. The second face 108 of the dual sided frame 102 similarly defines a plane of the second face 108. A second face 120 of the first knee brace 104 is coincident with the plane of the second face 108 of the dual sided frame 102.
Referring particularly to FIG. 3, the first knee brace 104 also includes a longitudinal support beam 302. The longitudinal support beam 302 of the first knee brace 104 enables the first knee brace 104 to adjustably extend along a path parallel to the longitudinal axis 110 of the dual sided frame 102. The longitudinal support beam 302 has a plurality of detents. Each detent is operable to maintain an outer longitudinal surface 304 of the first knee brace 104 at a different predetermined longitudinal distance from the first longitudinal end 116 of the dual sided frame 102. The detents may be dimples, depressions, or holes in the longitudinal support beam 302 of the first knee brace 304. In one embodiment, each detent as a hole, and the dual sided frame 102 includes a first knee brace tube 306 and a spring-loaded first knee brace pin 308. The first knee brace tube 306 is operable to receive at least a portion of the longitudinal support beam 302 of the first knee brace 104.

The second knee brace 310 also has a second face 316 coincident with the plane of the second face 108 the second side of the dual sided frame 102.
Referring to FIG. 5, the first knee brace 104 has a cross section with respect to the longitudinal axis 110 that is generally trapezoidal. The second knee brace 310 is similarly shaped. Similarly, the dual sided frame 102 has a cross section with respect to the longitudinal axis 110 adjacent the first longitudinal end 116 of the dual sided frame 102 that is generally trapezoidal. The first knee brace 104 has a height less than a height of the dual sided frame 102, in the first knee brace 104 is approximately vertically centered with respect to the dual sided frame 102. The first knee brace 104 may also extend slightly above vertically centered with respect to the dual sided frame 102.
Referring to FIG. 2, the rack 100 also includes a first bottom beam 202, a second bottom beam 204, and a pickup support pipe 206. The first bottom beam 202 is at the first longitudinal end 116 of the dual sided frame 102. The second bottom beam 204 is at the second longitudinal end 312 of the dual sided frame 102. The second longitudinal end 312 is opposite the first longitudinal end 116. The first bottom beam 202 includes a plurality of rollers 208 extending through a bottom surface to 10 of the first bottom beam 202. The pickup support pipe 206 extends substantially parallel to the longitudinal axis 110 from the second longitudinal end 312 of the dual sided frame 102. In one embodiment, the pickup support pipe 206 is in contact with the second bottom beam 204 of the dual sided frame 102. The pickup support pipe 206 and the rollers 208 enable an operator to move the rack 100 by slightly lifting the pickup support pipe such that the weight of the rack 100 is mostly on the rollers 208. The operator can then move the rack 100 on the rollers 208 to a desired location. A top side 502 of the first bottom beam 202 and a topside 504 of the second bottom beam 204 are angled downward near the center of the rack 100. That is, the top side 502 of the first bottom beam 202 and the topside 504 of the second bottom beam 204 are higher further away from the longitudinal axis 110 and closer to the longitudinal axis 110. In one embodiment, the corresponding sections of the topsides of the first and second bottom beams are each perpendicular to the plane of their respective faces of the dual sided frame 102 as shown in FIG. 5.
Referring to FIG. 4, in one embodiment, the rack 100 further includes a first stop arm 402, and a second stop arm 404. The first stop arm 402 is operable to adjustably extend from the first longitudinal end 116 of the dual sided frame 102. The first stop arm includes a longitudinal support beam 406 and an axial protrusion 408 attached to the longitudinal support beam 406. The actual protrusion 408 extends generally away from the longitudinal axis 110 beyond the first face 106 of the dual sided frame 102. The second stop arm 404 is operable to adjustably extend from the first longitudinal end 116 of the dual sided frame 102. The second stop arm 404 includes the longitudinal support beam 410 and an axial protrusion 412. The actual protrusion 412 is attached to the longitudinal support beam 410, and the axial protrusion 412 extends generally away from the longitudinal axis 110 beyond the second face 108 of the dual sided frame 102. The distance between the axial protrusion 408 of the first stop arm 402 in the first longitudinal end 116 of the dual sided frame 102 is independent of the distance between the axial protrusion 412 of the second stop arm 404 and the first longitudinal end 116 of the dual sided frame 102.
In one embodiment, the longitudinal support beams of the first and second stop arms include a plurality of detents operable to maintain their respective axial protrusions at different predetermined distances from the first longitudinal end 116 of the dual sided frame 102. For example, the longitudinal support beam 406 of the first stop arm 402 has a plurality of detents. Each detent is operable to maintain the axial protrusion 408 of the first stop arm 402 at a different predetermined longitudinal distance from the first longitudinal end 116 of the dual sided frame 102. In one embodiment, each detent is a hole. It is contemplated that each detent may be a depression or dent instead of a hole. The dual sided frame 102 also includes a first stop arm tube 420 and a spring-loaded first stop arm pin 422. The first stop arm tube 420 is operable to receive at least a portion of the longitudinal support beam 406 of the first stop arm 402. The portion of the longitudinal support beam 406 of the first stop arm 402 received by the first stop arm tube 420 is a function of the distance between the axial protrusion 408 of the first stop arm 402 and the first longitudinal end 116 of the dual sided frame 102. The spring-loaded first stop arm pin 422 is operable to engage one of the plurality of holes (i.e. detents) in the longitudinal support beam 406 of the first stop arm 402. In one embodiment the adjustable stop arms and knee braces enable each side of the rack 100 to hold or support a glass sheet up to 102 inches tall and 144 inches long or wide. Additionally, because the stop arms are independently adjustable, one side can hold a 144 inch wide or long glass sheet while the other side holds a 130′′ wide or long glass sheet.
In one embodiment, the axial protrusions of the stop arms are hinged such that they can be folded up within the footprint of the dual sided frame 102. For example, the axial protrusion 408 of the first stop arm 402 is attached to the longitudinal support beam 406 of the first stop arm 402 via a hinge. Optionally, the hinge includes a latch to hold the axial protrusion in a fixed rotational position. In a first position of the hinge, the axial protrusion 408 extends substantially horizontally, and in a second position of the hinge, the actual protrusion 408 extend substantially vertically. The axial protrusions of the stop arms are operable to engage one or more glass sheets and prevent them from sliding. For example, the axial protrusion 408 of the first stop arm 402 is operable to engage one more glass sheets supported by the first face 106 of the dual sided frame. The axial protrusion 408 of the first stop arm 402 prevents the one or more glass sheets supported by the first face 106 of the dual sided frame 102 from sliding parallel to the longitudinal axis 110 toward the first longitudinal end 116 of the dual sided frame 102. In one embodiment, the first stop on 402 further includes a first bumper 604, and the second stop arm 404 further includes a second bumper 602. The bumpers are at the first longitudinal ends of their respective stop arms. The bumpers may be, for example, polyurethane or rubber, and help to prevent shocking the glass if the rack 100 is pushed into an object such as a wall.
In one embodiment, the rack 100 further includes a pair of forklift tubes 610. The pair of forklift tubes 610 are sized and positioned to accept forks of a forklift such that the glass transport rack 100 may be moved by a forklift. Referring to FIG. 2, the pair of forklift tubes 610 is attached to the bottom of the pickup support pipe 206 about a center of the dual sided frame. Each tube 610 may be 3 inches tall, 8 inches wide, and 20 inches long with a 1⁄4 inch wall.
Although described herein as spring-loaded, it is contemplated that the pins engaging the detents of the longitudinal support beams disclosed herein may be other than spring loaded. For example, gravity may be used to hold a standard pin within the detent when the detent is a hole.
