DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIGS. 1-10 illustrate a modular loading dock 10 with a mobile base 12 and a housing 32 with a modular frame 34. 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.

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.

Housing 32 includes modular frame 34 which is mounted onto base 12 in sections, as seen in FIG. 1. 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. 1.

FIGS. 2-3 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 grade 46. FIG. 2 illustrates adjustable feet 44 contacting the grade 46 which is fairly level. FIG. 3 illustrates how adjustable feet 44 can conform to grade 46 when it is not level. As seen in FIG. 3, adjustable feet 44 are able to be adjusted independently of each other. In FIG. 3, the adjustable feet 44 shown are in different positions so as to securely contact the grade 46. Adjustable feet 44 are able to be adjusted between a left side to right side direction as well as adjustable in a front-to-back direction so as to allow each of the adjustable feet 44 to conform to grade 46.

FIGS. 2-3 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.

FIGS. 4-6 illustrate that mobile base 12 has at least two, opposing adjustable plates 48, and each plate 48 is located between two adjustable feet 44. 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. 2-3. A bolt with two nuts secures adjustable plate 48 in between two adjustable feet 44, as seen in FIGS. 2-3. 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.

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 grade 46, 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.

FIGS. 4-5 illustrate that adjustable plate 48 also shifts with grade 46. FIG. 4 illustrates adjustable plate 48 in a relatively horizontal position. In contrast, FIG. 5 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. 4-6.

FIG. 6 also illustrates in detail how adjustable plate 48, through the use of bolt 60 and nut 62, can be adjusted. As seen best in FIG. 6, adjustable plate 48 includes numerous slots through which bolt 60 and nut 62 can slide in an upward and downward direction as needed to help adjustable plate 48 conform to 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.

The adjustment of adjustable leg member 14 and adjustable plate 48 is seen in FIG. 7. FIG. 7 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. 7. Locking bolt 52 goes through an opening in a lower end 66 of adjustable leg member 14 (see FIG. 7) so as to secure adjustable leg member 14 in the desired position.

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 independently 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 independently of every other adjustable leg member 14.

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

FIGS. 8-9 illustrate how base 12 can be secured in different ways to a building or other preexisting structure 26.

The drawings also illustrate that dock leveler 58 has a lower end 22 and an upper end 24 (as seen best in FIGS. 4-5). 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 FIGS. 4-5. Lip 30 is able to be activated between an extended/engaged position to contact a truck bed and a retracted/disengaged position (not shown).

FIG. 10 is an exploded view which illustrates the interaction between housing 32, including frame 34 and mobile base 12. Dock leveler 58 with lip 30 can also be seen in FIG. 10. Frame-top wall 40 as well as opposed frame-sidewalls 38 are also seen in FIG. 10. Housing 32 can be secured to a wall of a pre-existing structure 26. (See FIG. 1.) Base 12 and housing 32 are removable and able to be transported to different locations.

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

FIG. 11 illustrates that mobile base 12 can include a tensioned-vinyl covering 68 over housing 32 and frame 34. Integral flashing 70 is also used in conjunction with covering 68. FIG. 12 is a side view of mobile base 12 with covering 68 over housing 32 and frame 34. FIGS. 13-14 show integral flashing 70 and how covering 68 is fastened to a building or other preexisting structure 26. Covering 68 is inserted into a hem and is then folded over a flashing bar 70, as seen in FIG. 14, and then fastened with a screw 80 or any other type of suitable securement.

An extension portion 72, as seen in FIG. 15, is connected to mobile base 12 on a distal end 78 and connected to a building 26 on a proximal end 76. The extension portion 72 includes covering 68. FIG. 15 shows the at least one adjustable leg member 74 on a proximal end 76 of the extension portion 72. Extension portion 72 and covering 68 can be made of any length or width to suit a particular installation and is not limited to the size shown in FIG. 15.

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.
