- FIGS. 1-3 schematically illustrate a number of the principles of the dolly-pallet 2 of the present invention.
- the load bearing deck 4 may be alternately supported by the retractable support skid 6 or the wheel elements 8 .
- the displacement mechanism of the present invention provides a substantially locked support state when the load bearing deck 4 may be alternately supported by the retractable support skid 6 such that retractable support skid 6 is substantially locked from vertical displacement (as seen in FIGS. 6A, 7A and 9 ).
- Initial displacement of the skid during the retraction process is along an upward substantially vertical path. In this way, the center of mass of the load is lowered vertically, thereby reducing stress on the displacement mechanism, until the load is supported by the wheel elements 8 .
- the retractable support skid 6 may be further displaced along an upward substantially arcuate path to move it away form the wheel elements 8 , allowing them to swivel if they are so configured. Therefore, the two-stage displacement motion preferably corresponds to a high force/torque motion sufficient to the retractable support skid 6 when under load, followed by a low force/torque motion for displacing the unloaded retractable support skid 6 from the region of the wheels along the arcuate path.
- wheel elements 8 may be configured to swivel. That is, to rotate about a vertical axis such as, but not limited to, a caster. Therefore, only those retractable support skids 6 associated with swivel wheel elements 8 s need be displaced further to allow the swivel wheel elements freedom to swivel. This is illustrated in FIG. 3 where only retractable support skid 6 a is displaced away form the wheel elements 8 s.
- displacement mechanism elements that serve the same or similar function in each of the embodiments herein described are numbered the same even though there may be slight differences in their individual configurations.
- FIG. 4 illustrates a first preferred embodiment of a displacement mechanism 10 .
- the retractable support skid 6 is retracted and lowered along a substantially vertical path by support struts 12 , which are attached to the rotating lifting bars 14 by eccentric attachment shafts 16 .
- the rotating lifting bars 14 are driven by gears 18 that mesh with drive gears 20 deployed on drive shaft 24 .
- FIGS. 6, 6A and 6 B illustrate a variant 40 of the displacement mechanism of FIG. 4 .
- the gears 18 mesh with worm gear 42 , which is accessible from the top of the load bearing deck 4 .
- FIGS. 6A and 6B Also seen clearly in FIGS. 6A and 6B is the process by which the retractable support skid 6 is retracted and lowered along a substantially vertical path by support struts 12 .
- the parallel support struts 12 are pivotally attached at one end to the retractable support skid 6 and at the other end to the eccentric attachment shafts 16 .
- the eccentric attachment shafts 16 are located at the bottom of their circular path, the retractable support skid 6 is in contact with the ground surface and supporting the dolly-pallet (as seen in FIG.
- the retractable support skid 6 may be brought back into contact with the ground surface and the wheel elements 8 lifted, thereby transferring support of the dolly-pallet from the wheel elements 8 back to the retractable support skid 6 (as seen in FIG. 1 ) by rotating the rotating lifting bars 14 in a clockwise direction and displacing the retractable support skid 6 first along a downward arcuate path toward the wheel elements 8 , and then in a substantially downward vertical path to the ground surface.
- FIGS. 7, 7A , 7 B, 8 and 8 A A second preferred embodiment of a displacement mechanism 60 is illustrated in FIGS. 7, 7A , 7 B, 8 and 8 A.
- the retractable support skid 6 is retracted and lowered along a substantially vertical path by support struts 12 , which are attached to levers 62 that extend from the rotating lifting bars 14 .
- the rotating lifting bars 14 are driven by gears 18 , which in this embodiment may be driven, by either the drive gears 20 deployed on drive shaft 22 of FIG. 4 , or the worm gear 42 of FIG. 6 .
- FIG. 7A illustrates the position of the levers 62 when the retractable support skid 6 is in contact with the ground surface and supporting the dolly-pallet (as seen in FIG. 1 ).
- rotating lifting bars 14 rotate (here again in a counter-clockwise direction) the levers 62 retract the retractable support skid 6 along a substantially vertical path bringing the wheel elements 8 into contact with the ground surface and thereby transferring support of the dolly-pallet from the retractable support skid 6 to the wheel elements 8 (as seen in FIG. 2 ).
- An optional feature of the displacement mechanism of the present invention is the resilient snap-lock arrangement 66 associated with the pivotal interconnection of the support struts 12 and the lever 62 .
- the resilient snap-lock arrangement 66 helps maintain positional alignment between the support struts 12 and the lever 62 when the skid 6 is supporting the dolly-pallet and during the displacement along the substantially vertical path.
- the resilient snap-lock arrangement 66 helps maintain positional alignment between the support struts 12 and the lever 62 during displacement of the skid 6 along the substantially arcuate path.
- the retractable support skid 6 may be brought back into contact with the ground surface and the wheel elements 8 lifted, thereby transferring support of the dolly-pallet from the wheel elements 8 back to the retractable support skid 6 (as seen in FIG. 1 ) by rotating the rotating lifting bars 14 in a clockwise direction and displacing the retractable support skid 6 along a downward arcuate path toward the wheel elements 8 , and then in a substantially downward vertical path to the ground surface.
- FIGS. 13-17 A manually operated “knockdown” variation of the second preferred embodiment of a displacement mechanism 260 is illustrated in FIGS. 13-17 .
- the retractable support skid 6 is retracted and lowered along a substantially vertical path by support struts 12 , which are pivotally attached to levers 62 that extend from the rotating lifting bars 14 .
- the rotating lifting bars 14 The rotating lifting bars 14 .
- the retractable support skid 6 is initial retracted from a position of supporting the dolly-pallet (as seen in FIGS.
- “knocking” release button 262 which is mechanically linked to at least on of the rotating lifting bars 14 , with a tool such as, but not limited to, a hammer, thereby freeing the displacement mechanism 260 from a locked position.
- This action also causes the release button to move laterally, causing rotation of rotating lifting bars 14 , which may be mechanically linked by gears such as is illustrated in FIG. 5 , thereby raising the retractable support skid 6 along a substantially vertical path bringing the wheel elements 8 into contact with the ground surface and thereby transferring support of the dolly-pallet from the retractable support skid 6 to the wheel elements 8 (as seen in FIGS. 2, 14 and 15 ).
- Displacement of the retractable support skid 6 along a substantially arcuate path up and away from the wheel elements 8 , thereby allowing the wheel elements 8 freedom to swivel (as seen in FIGS. 3, 16 and 17 ) is accomplished by rotating the lifting lever 264 , here, in a counter-clockwise direction, thereby rotating the rotating lifting bars 14 .
- lifting projection 64 of the lever 62 engages the edge of support struts 12 ( FIG. 17 )
- the support struts 12 begin to rotate with the rotating lifting bars 14 .
- the retractable support skid 6 may be brought back into contact with the ground surface and the wheel elements 8 lifted, thereby transferring support of the dolly-pallet from the wheel elements 8 back to the retractable support skid 6 (as seen in FIGS. 1 and 13 ), by rotating the lifting lever 264 , and therefore, the rotating lifting bars 14 in a clockwise direction and displacing the retractable support skid 6 along a downward arcuate path toward the wheel elements 8 , and then in a substantially downward vertical path to the ground surface. This will also bring the release button 262 back into its original position and the displacement mechanism 260 to a locked position, as illustrated in FIG. 13 .
- FIGS. 15 and 17 illustrate two lifting levers 264 configured on opposite ends of one of the lifting bars 14 . This is not intended as a limitation of the present invention, rather it is an example of one possible configuration within the scope of the present invention. It will be understood that a single lifting lever 264 would provide similar results.
- FIGS. 9 and 9 A A third preferred embodiment of a displacement mechanism 80 is illustrated in FIGS. 9 and 9 A.
- the retractable support skid 6 is retracted and lowered along a substantially vertical path by support struts 12 , which are attached to drive screws 82 that extend from drive gears 84 , which are internally treaded such that drive screws 82 are raised and lowered by turning drive gears 84 .
- the drive gears 84 are driven by worm gears 86 configured on drive shaft 88 .
- the retractable support skid 6 is retracted along a substantially vertical path from contact with the ground surface and supporting the dolly-pallet (as seen in FIG. 1 ) by rotating drive shaft 88 in a counter-clockwise direction.
- the retractable support skid 6 retracts, the wheel elements 8 are brought into contact with the ground surface, thereby transferring support of the dolly-pallet from the retractable support skid 6 to the wheel elements 8 (as seen in FIG. 2 ).
- support struts 12 are pivotally attached to drive screws 82 , the retractable support skid 6 may be displaced along a substantially arcuate path up and away from the wheel elements 8 ( FIG. 8 ), thereby allowing the wheel elements 8 freedom to swivel (as seen in FIG. 3 ). This may be done manually or by any other suitable drive mechanism (not shown).
- retractable support skid 6 may be brought back into contact with the ground surface and the wheel elements 8 lifted, thereby transferring support of the dolly-pallet from the wheel elements 8 back to the retractable support skid 6 (as seen in FIG. 1 ) by rotating drive shaft 88 in a clockwise direction and displacing the retractable support skid 6 along a substantially downward vertical path to the ground surface.
- load bearing deck 4 may be configured such that the drive elements, such as the drive shaft 24 , rotating lifting bars 14 , and the associated gears, of these first three embodiments of displacement mechanisms of the present invention may be deployed within the structure of the load bearing deck 4 itself. Alternatively, these drive elements may be attached to the underside of the load bearing deck 4 .
- FIGS. 10-12 Illustrated in FIGS. 10-12 is a fourth embodiment 100 of a displacement mechanism by which the retractable support skid 6 is retracted and lowered along a substantially vertical path.
- the retractable support skid 6 is upwardly biased toward the legs 102 that extend downwardly from the load beard deck 4 of the dolly-pallet.
- the retractable support skid 6 is drawn upward along a substantially vertical path toward the bottom surfaces of legs 102 , thereby bringing the wheel elements 8 into contact with the ground surface and transferring support of the dolly-pallet from the retractable support skid 6 to the wheel elements 8 .
- the retractable support skid 6 may be brought back into contact with the ground surface and the wheel elements 8 lifted, thereby transferring support of the dolly-pallet from the wheel elements 8 back to the retractable support skid 6 (as seen in FIG. 1 ) by laterally displacing the wedges 104 back into the region between legs 102 and retractable support skid 6 , thereby displacing the retractable support skid 6 along a substantially downward vertical path to the ground surface.
- displacement mechanism of the present invention may by driven manually or by a drive system, which may be in the form of an onboard drive system, or as a drive system accessory unit. Additionally, an onboard drive system may be activated via a control panel on the dolly-pallet, or remotely via a remote control system.
