DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(12) The novel features which are believed to be characteristic of the present invention, as to its structure, organization, use and method of operation, together with further objectives and advantages thereof, will be better understood from the following discussion. It will be noted that, in the drawings, like reference numerals depict like elements.

(13) Applicant refers first to FIGS. 1 to 6 which shows the prior art clamping assembly described in U.S. Pat. No. 8,608,122. It can be noted the clamp assemblies in keeping with that invention, or the present invention, may find other uses, but the use of the clamping assemblies to secure fairings to a cargo trailer is their principal intended use.

(14) In general, a plurality of I-beams are found beneath the floor of a cargo traiier, in a manner such that the trailer floor is secured to the upper horizontal flat portion of the I-beams. Thus, the lower horizontal flat portions of the I-beams are freely accessible, so as to permit securement of the clamping assemblies of the present invention.

(15) Referring now to FIGS. 1 to 6, it will be seen that a clamp assembly 20 in keeping with the prior art, as described in U.S. Pat. No. 8,608,122, comprises the assembly of three major components. They are a pair of side blocks 22 (see FIGS. 1 and 2), and a single clamping block 40 (see FIG. 3). When assembled as shown in FIGS. 4 and 5, it can be appreciated that the assembly is, to all intents and purposes, monolithic.

(16) As was described in U.S. Pat. No. 8,608,122, the entire clamp assembly 20 can be effected merely by the placement and tightening of one single bolt 52. It will also be appreciated, therefore, that placement and then securement of the clamp assembly 20 at the end of an I-beam simply requires that the pieces may either be loosely assembled and put into place, or held or otherwise kept in place while the bolt 52 is put into place.

(17) Now, referring to FIGS. 1 and 2, details of the side blocks 22 will be discussed. It is seen that each side block 22 is formed generally in the shape of an inverted “L”. Each of the pair of side blocks 22 has an upper surface 24, an outer side surface 26, and end surfaces 28, all of which are in mutually perpendicular relationship one to another. There is a bottom surface 30 which is parallel to the upper surface 24. A lower clamping surface 32 is parallel to the upper surface 24. There is also an inclined wedge surface 34 which extends downwardly and outwardly from its intersection with the lower clamping surface 32, to its intersection with the bottom surface 30. At least one opening 54, and more preferably, at least two other openings 57, are formed through the leg of the “L”, and passes through the thickness thereof between the respective side surface 26 and inclined wedge surface 34 of each of the side blocks 22.

(18) The prior art clamping block 40 is shown in FIG. 3, and the clamping block 40 is formed generally in the shape of a “T”. The central body of this prior art clamping block 40 is designated as 42, and a flat surface which extends across the head of the “T” is designated at 44. It is seen that the central body 42 and the flat surface 44 are typically, essentially perpendicular one to the other. There is an inner surface 46 which is at the foot of the “T”, and the inner surface 46 is also essentially perpendicular to the central body 42. A bottom surface 48 is found at least below the leg of the “T”, and is also parallel to central body 42.

(19) The clamping block 40 is particularly characterized by the presence of a pair of sloping wedge surfaces 50 which are preferably formed along at least a portion of central body the sides of the leg of the “T”, at the sides thereof. Each sloping wedge surface slopes downwardly and inwardly from its respective intersection with the upper surface of central body 42 to its respective intersection with the bottom surface 48.

(20) It is possible that the distance or height between the top and bottom surfaces of clamping block 40 may be sufficiently small so that the bottom surface 48 is disposed above the bolt 52 when it is in place. However, more typically there is at least one opening 55, and more preferably three openings 55, which are formed through the width of the leg of the “T” of the clamping block, so as to pass therethrough from one side to the other. Any one of the openings 55 is such as to accommodate a bolt 52 when it is passed therethrough.

(21) In any event, when the side blocks 22 and the clamping block 40 are assembled together with the bolt 52, and are placed so that the respective lower clamping surfaces 32 of the pair of side blocks 22 faces a respective upper surface of the pair of opposed flanges of the I-beam, the respective inclined wedge surfaces 34 of the side blocks 22 will face respective sloping wedge surfaces 50 of the clamping block 40. Tightening of the bolt 52 which is passed through a combination of openings 54 and 57 (and preferably 55 when present) will cause a sliding and wedging action of the sloping wedge surfaces 50 of the clamping block 40 relative to and in opposition to the inclined wedge surfaces 34 of the respective side blocks 22. Thus, a clamping action is secured between the side blocks 22 and through the width of the leg of the “T” of the clamping block 40, which clamping action secures the clamp assembly 20 in place on the opposed lower plate portions of the I-beam 60. Still further, a clamping action is induced between the upper surface 42 of the clamping block and the bottom surface 62 of the respective I-beam 60 to which the clamp assembly is attached. In this fashion, I-beams having different widths and thicknesses can be accommodated using clamp assembly 20.

(22) Further, clamping block 40 also optionally additionally includes a second planar face 45 which is essentially co-planar with outer surface 44. Second planar face 45 extends downwardly from block 40, and includes slots, or openings 47, which can be used as additional or replacement attachment points to attach panel 15 to clamping block 40. This is particularly desirable when I-beams 60 of different depths are used, so that openings 64 in adjacent clamping assemblies are not in horizontal alignment. Planar face 45 might also be inwardly inclined away from face 44, if desired.

(23) In FIGS. 4 and 5, and in particular in FIG. 6, it can more clearly been seen that a single bolt 52 is used to clamp side blocks 22 to clamping block 40, in position on the lower, flat portion of I-beam 60. It can be seen that tightening of bolt 52 causes not only side blocks 22 to clamp against block 40, but the sloping wedge surfaces 50, and the inclined wedge surfaces 34, also cause side blocks 22 to compress against I-beam 60, and thus lock clamping assembly 20 in place.

(24) Also in FIG. 6, it can be seen that the inclined wedge surfaces 34, and sloping wedge surfaces 50 preferably are machined so as to have corresponding angles, and thus, be essentially flat and square to one another in use. Typically, the wedge surfaces are at between 15 to 45° relative to a vertical line, and more preferably, between 20 and 30° to a vertical line. A series of corrugations 66 is also preferably formed or provided on each lower clamping surface 32 of each of the side blocks 22. The purpose of these corrugations 66 is provide additional grip on I-beam 60.

(25) It will be noted that the various components are typically injection moulded having a plurality of recesses 78 formed therein. Accordingly, a plurality of ribs 80 is created between the recesses 78. This manufacturing technique has the advantage that the weight of the injection moulded side blocks 22 and clamping block 40 will be reduced, while at the same time their rigidity in a direction parallel to the respective ribs will be increased.

(26) Typically, and as can be appreciated from a cursory inspection of FIGS. 4, 5 and 6, and as seen in U.S. Pat. No. 8,608,122, clamping block 40 is disposed in a generally horizontal disposition which extends along I-beam 60. As such, clamping block 40 is generally supported and braced by I-beam 60.

(27) It should be particularly noted that in this prior art embodiment, flat surface 44 is disposed in a perpendicular disposition with respect to the central body, and thus perpendicular to the attachment I-beam.

(28) It will be further understood that the clamp assembly 20 of the prior art, is such that a fairing panel can be secured to an I-beam in such a manner that the plane of the fairing panel and the longitudinal axis of each I-beam 60 to which it is attached, are substantially perpendicular, one to the other.

(29) It will also be clear that struts, straps, or any other fairing securing devices, can be attached to the clamping assemblies, in the manner described in U.S. Pat. No. 8,608,122.

(30) In FIGS. 7 and 8, a clamping block 100 in accordance with the present invention is shown, which clamping block 100 is used as a replacement for clamping block 40 of the prior art. Clamping block 100 has a central body 102, and a flat surface 104 at one end of the central body. Flat surface 104 is fabricated at an angle of 15° to the axis of the central body 102. A fairing attachment surface 106 is attached to flat surface 104, and thus, the central body can be attached to a fairing at approximately 15° to the axis of the central body 102, and the overall clamping assembly.

(31) At the other end of central body 102 is a second flat end 108, which is essentially at 90° to the axis of the central body 102. If desired, this end 108 could be used to provide a perpendicular flat surface to which an attachment surface could be attached.

(32) More preferably however, as shown in FIGS. 9 and 10, both ends 114 and 118 of clamping body 110 are provided at a 15° angle to the central body 112 of clamping block 110. By providing flat surfaces at the same angle, but opposing angles, at each end of central body 112, central block 110 is reversible in the clamping assembly, and thus, the clamping assembly can be used on either the right or left side of the trailer.

(33) Thus, it is apparent that there has been provided, in accordance with the present invention, a clamping assembly which fully satisfies the goals, objects, and advantages set forth hereinbefore. Therefore, having described specific embodiments of the present invention, it will be understood that alternatives, modifications and variations thereof may be suggested to those skilled in the art, and that it is intended that the present specification embrace all such alternatives, modifications and variations as fall within the scope of the appended claims.

(34) Additionally, for clarity and unless otherwise stated, the word “comprise” and variations of the word such as “comprising” and “comprises”, when used in the description and claims of the present specification, is not intended to exclude other additives, components, integers or steps. Thus, the word “comprise”, and variations such “comprises” or “comprising”, will be understood to imply the inclusion of a stated integer or step or group of integers or steps, but not to the exclusion of any other integer or step or group of integers or steps.

(35) Further, the invention illustratively disclosed herein suitably may be practiced in the absence of any element which is not specifically disclosed herein.

(36) Moreover, the words “substantially”, “essentially”, “typically”, “generally” or the like, when used with an adjective or adverb is intended to enhance the scope of the particular characteristic; e.g., “substantially planar” is intended to mean planar, nearly planar and/or exhibiting characteristics associated with a planar element.

(37) Further, use of the terms “he”, “him”, or “his”, is not intended to be specifically directed to persons of the masculine gender, and could easily be read as “she”, “her”, or “hers”, respectively.

(38) Also, while this discussion has addressed prior art known to the inventor, it is not an admission that all art discussed is citable against the present application.

(39) Other modifications and alterations may be used in the design and manufacture of the apparatus of the present invention without departing from the spirit and scope of the accompanying claims.
