Adjustable Mobile Loading Dock

Abstract

An apparatus and related method for a dock housing for a pre-existing loading dock. The dock housing includes a base with top and bottom surfaces and front, back and opposed sidewalls. The front wall has integral fork pockets for interaction with forks on a fork truck for movement of the base into a desired location and the top surface has an opening to receive a dock leveler into such opening. Also included is a modular frame mounted onto the base in sections, the sections including a frame-front wall, opposed frame-sidewalls and a frame-top wall, the frame-front wall having a trailer-receiving opening to receive a trailer, the frame-sidewalls including a slotted-base attachment for securement of the base and sidewalls together. The dock housing is formed by securing the frame-sidewalls to a wall of a pre-existing building as well as securing the base, the frame-front wall and the frame-top wall together.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0029] FIGS. 1-10 illustrate a modular loading dock 10 with a mobile base 12. FIG. 1 illustrates that base 12 includes at least two but preferably four, opposing, adjustable leg members 14. Base 12 has both top and bottom surfaces 16, 18, with top surface 16 having an opening 20 to receive a dock leveler 58 into opening 20.

[0030] As seen best in FIG. 1, mobile base 12 has at least two, opposing adjustable plates 48, each plate 48 located between two adjustable feet 44. Each adjustable plate 48 includes one or more securement structures, the securement structures have a bolt 60 and at least one or two nuts 62 to secure bolt 60 in the desired position.

[0031] FIGS. 2-3 illustrate in detail how adjustable plate 48, through the use of bolt 60 and nut 62, can be adjusted. As seen best in FIGS. 2-3, adjustable plate 48 includes numerous slots which bolt 60 and nut 62 can slide in an upward and downward direction as needed to help adjustable plate 48 conform to the grade 46. Once adjustable plate 48 is in the desired position, bolt 60 and nut 62 are secured in place in slot 64 by tightening nut 62. Preferably, there are two nuts 62 one on each side of bolt 60. FIG. 2 illustrates adjustable plate 48 not conformed to grade 46. In contrast, FIG. 3, illustrates adjustable plate 48 conformed to grade 46.

[0032] FIGS. 2-3 illustrate that adjustable plate 48 also shifts with the grade 46. FIG. 2 illustrates adjustable plate 48 in a relatively horizontal position. In contrast, FIG. 3 illustrates that adjustable plate 48 is in an angled position (in a direction angled down to the right of the drawing) showing that adjustable plate 48 has conformed to grade 46 with adjustable feet 44. A brace member 50 is connected to adjustable plate 48 on one end and provides added strength to mobile base 12 as seen in FIGS. 2-3.

[0033] It is important to note that each side of base 12 has an adjustment plate 48 and that each adjustment plate 48 on either side of base 12 can be adjusted independent of the other adjustment plate 48 on the other side of base 12. Being able to adjust adjustment plate 48 to the exact contour of grade 46 allows for a more secure attachment to grade 46 and greater stability of base 12. This is also true of each of the four adjustable leg members 14. Each of the four adjustable leg members 14, which are part of base 12, can be adjusted independent of every other adjustable leg member 14.

[0034] Base 12 can be secured to any type of grade 36 including but not limited to gravel, asphalt or concrete. It is important to note that base 12 can secured to ground 36 by any known method and all such methods are within the scope of the application.

[0035] The adjustment of adjustable leg member 14 and adjustable plate 48 is seen in FIG. 4. FIG. 4 also illustrates in close up detail the interaction and adjustability of leg member 14 and adjustable plate 48. First locking nut 54 and second locking nut 56 are each located on locking bolt 52 as seen in FIG. 4. Locking bolt 52 goes through an opening in a lower end 66 of adjustable leg member 14 (see FIG. 4) so as to secure adjustable leg member 14 in the desired position.

[0036] Mobile base 12 with two of the four adjustable leg members are seen in FIGS. 5-6. FIG. 5 illustrates mobile base 12 not adjusted to grade 46, and in contrast, FIG. 6 shows mobile base 12 adjusted to grade 46. Specifically, in FIG. 6, adjustable feet 44 on each adjustable leg member 14 have been adjusted to conform to grade 46.

[0037] FIGS. 7-8 illustrate adjustable leg member 14 in detail and that adjustable leg member 14 includes at least two adjustable feet 44 on each adjustable leg member 14. Adjustable feet 44 are able to contact and conform to the grade 46. FIG. 7 illustrates adjustable feet 44 not contacting the grade 46 which is fairly level. FIG. 8 illustrates how adjustable feet 44 can conform to the grade 46 when it is not level. As seen in FIG. 8, adjustable feet 44 are able to be adjusted independently of each other. In FIG. 8, the adjustable feet 44 shown are in different positions so as to securely contact the grade 46. Adjustable feet 44 are able to adjustable between a left side to right side direction as well as adjustable in a front-to-back direction so as to allow the each of the adjustable feet 44 to conform to the grade 46. Adjustable plate 48 has a portion of each end which is sandwiched between two adjustable feet which are located on adjustable leg member 14 as seen in FIGS. 7-8. A bolt with two nuts secures adjustable plate 48 in between two adjustable feet 44 as seen in FIGS. 7-8.

[0038] FIGS. 7-8 illustrate that adjustable leg members 14 include one or more adjustment structures, the adjustment structures include a locking bolt 52, a first locking nut 54 and a second locking nut 56. When first locking nut 54 and second locking nut 56 are loosened, the height of adjustable feet 44 can be changed so as to closely conform to grade 46.

[0039] Adjustable leg members 14 can be adjusted to conform to grade 46 by first loosening nuts 62 on each adjustable plate 48. Preferred embodiments of mobile base 12 will include two opposing adjustable plates 48. Nuts 62 must be loosened on each adjustable plate 48. Preferred embodiments include four adjustable leg members on each mobile base 12. Next, first locking nut 54 and second locking nut 56 on each of the four adjustable leg members 14 must be loosened. Loosening first locking nut 54 and second locking nut 56 allows the height of each of the adjustable feet 44 to be adjusted so that it contacts the grade 46. Each adjustable leg member 14 includes two adjustable feet 44. A mobile base will therefore, have eight adjustable feet 44 in all. Once each of the eight adjustable feet 44 are contacting the grade, first locking nut 54 and second locking nut 56 can be tightened on each adjustable leg member 14. At the same time each nut 62 on adjustment plate 48 can be tightened as well.

[0040] The drawings also illustrate that dock leveler 58 has a lower end 22 and an upper end 24 as seen in best in FIG. 9. Upper end 24 abuts a preexisting structure 26 and lower end 24 includes a lower edge 28 which has a lip 30 as seen in FIG. 9. Lip 30 is able to be activated between an extended/engaged position to contact a truck bed and a retracted/disengaged position.

[0041] FIGS. 9-10 illustrate that housing 32 includes modular frame 34 which is mounted onto base 12 in sections. These sections include a frame-front wall 36, opposed frame-sidewalls 38 and a frame-top wall 40, frame-front wall 36 has a vehicle-receiving opening 42 to receive a back end of a vehicle as illustrated in FIG. 9. Housing 32 can be secured to a wall of a pre-existing structure 26. (See FIG. 9.) Frame 34 is self-standing (it can operate as a stand-alone platform and does not need any other structure to function) but frame 34 is versatile as well as modular as it can also be used with any platform, ramp, dock housing or an existing building. Base 12 and housing 32 are removable and able to be transported to different locations.

[0042] A lifting system is incorporated into dock leveler 58. The hydraulic lifts assist in lifting a section of dock leveler 58. However, any other lifting systems known in the art could be utilized as well. A variety of dock levelers of different sizes and shapes can be used and are within the scope of this application

[0043] Although the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
