Other aspects, features, and advantages will become apparent from the following detailed description when taken in conjunction with the accompanying drawings, which are a part of this disclosure and which illustrate, by way of example, principles of the inventions disclosed.
The accompanying drawings facilitate an understanding of the various embodiments.
In some embodiments, the elongated member 102 is a rectangular shape and may be, for example, approximately 8 inches by 2 inches by several feet or more. In other embodiments, the elongated member 102 may be larger or smaller than 8 inches by 2 inches. The elongated member 102 may be constructed of any suitable material, for example, wood, metal and/or plastic, or any suitable combination of materials. In some embodiments, for example, the elongated member 102 is made of a treated wood material, such as a treated pine. In some embodiments, the elongated member 102 is made of Treated Southern Yellow Pine. The elongated member 102 may be made of other wood materials in other embodiments. In some embodiments, for example, the elongated member 102 is made of Douglas Fir, Hem Fir or SPF (spruce-pine-fur). In yet other embodiments, the elongated member 102 is made of Canadian SPF.
In some embodiments, the elongated member 102 may be constructed of a wood material that is specifically chosen for its non-warping characteristics so that it is less prone to warp over time. In some embodiments, for example, the elongated member 102 is chosen such that the growth rings 154 are curved away from the cutout portion 104, as shown in the embodiment illustrated in
In some embodiments, the color of the elongated member 102 can be changed, for example, by staining or painting the elongated member 102. In some embodiments, the elongated member 102 and the insert 106 are both made of materials whose color can be changed so that the color of the elongated member 102 can be matched to the color of the insert 106. In other embodiments, the color of the elongated member 102 and the color of the insert 106 do not match. In some embodiments, a colored pigment or other material, such as an ethylene propylene diene monomer (EPDM) material, is added to the material from which the insert 106 is made (such as a rebonded rubber) to give the insert 106 a particular color. For example, in some embodiments a pigment is added to the base polymer from which the insert 106 is made. The insert 106 can be any suitable color based on the pigment, paint or other material that is added to the insert 106 during its formation.
In some embodiments, the elongated member 102 includes a cutout portion 104 that extends along at least a portion of a longitudinal axis 108 of the elongated member 102. As will be described in more detail below, the cutout portion 104 may be any suitable shape and in some embodiments includes a first sidewall 110, a second sidewall 112 and a floor 114.
In some embodiments, the cutout portion 104 is sized and shaped to hold at least a portion of the insert 106. The insert 106 may be any suitable size and shape that can be at least partially located in the cutout portion 104. For example, in some embodiments the insert 106 is rectangular in shape. In some embodiments, a top surface 132 of the insert 106 may be substantially flat or may be curved, for example, in a protruding, convex shape. The surfaces of the insert 106 may contact the sidewalls 110 and 112 and floor 114 of the cutout portion or may not contact one or more of the sidewalls 110 and 112 and/or the floor 114. In some embodiments, for example, the insert 106 has a curved bottom surface 156 and only a portion of the bottom surface 156 contacts the floor 114 or the sidewalls 110 and 112.
In some embodiments, the insert 106 is slightly smaller than the cutout portion 104 to allow for variations in the rate at which the insert 106 and the elongated member 104 expand and contract over time. For example, in some embodiments the elongated member 104 and the insert 106 may expand and contract at different rates as a result of variations in ambient temperature. In some embodiments, the insert 106 is held in a centered orientation in the cutout portion 104 by one or more coupling devices (see e.g., the coupling device 130 of
The surfaces of the insert 106 may also include a texture, such as, for example, a series of protrusions and recesses (not shown in
Referring now to
Referring again to
The cutout portion 104 may be symmetric about a centerline 118 of the elongated member 102, as shown in
The cutout portion 104 may also be any suitable size with respect to the elongated member 102. In some embodiments, for example, the cutout portion 104 occupies about 80 percent of the top surface 120 of the elongated member 102. As such, when the insert 106 is placed within the cutout portion 104, the insert 106 may also cover up to about 80 percent of the top surface 120 of the elongated member 102. In some embodiments, the cutout portion 104 occupies more than about 80 percent of the top surface 120 of the elongated member 102 (or more than about 80 percent of the width of the top surface 120) and, when the insert 106 is placed within the cutout portion 104, the insert 106 may also cover more than about 80 percent of the width or entirety of the top surface 120 of the elongated member 102. In other embodiments, the cutout portion 104 occupies less than about 80 percent of the top surface 120 (or less than about 80 percent of the width of the top surface 120) of the elongated member 102 and, when the insert 106 is placed within the cutout portion 104, the insert 106 may also occupy less than about 80 percent of the width or the entirety of the top surface 120 of the elongated member 102.
The cutout portion 104 may also have any suitable surface texturing to help secure the insert 106 within the cutout portion 104. For example, referring again to the embodiment of
Other surface texturing or modifications to the cutout portion 104 and/or the insert 106 may be used to further secure the insert 106 at least partially within the cutout portion 104. For example, in some embodiments, the insert 106 may include protrusions (not shown) that mate with corresponding recesses (not shown) in the cutout portion 104 so that the insert 106 may be “snapped” into place in the cutout portion 104.
In some embodiments, additional mechanisms may be coupled to the elongated member 102 and the insert 106 to further secure the insert 106 at least partially within the cutout portion 104. For example, in the embodiment of
Referring still to
The first and second sidewalls 110 and 112 may also be coupled to the insert 106 by attachment mechanisms 130. For example,
Referring now to
The insert 106 and the cutout portion 104 may also extend to any suitable depth in the elongated member 102. For example, in the embodiment shown in
Referring now to
In some embodiments, the cutout portions 104 extend through the sidewalls 168 of the elongated member 102, as shown in
Referring now to
In other embodiments, the elongated member 102 does not include a cutout portion 104 and the insert 106 is coupled directly to the top of the elongated member 102. This embodiment looks similar to the embodiment depicted in
In some embodiments, the intermediate frame members 206 are spaced apart from each other by a distance of about 12 inches. In other embodiments, the distance between the intermediate frame members 206 is more or less than 12 inches. For example, in some heavy-duty trailers 200 the intermediate frame members 206 are spaced apart from each other by a distance of about 6 inches. In some embodiments, the spacing of the intermediate frame members 206 is determined by the weight requirements of the trailer 200 and the structural strength of the material used to create the trailer floor, as will be described in more detail below.
While the intermediate frame members 206 are perpendicular to the first and second frame members 202 and 204 in the embodiment illustrated in
As described above, the flooring apparatuses 100 may be configured to support cargo that is placed on a trailer 200. The flooring apparatus 100 may, in some instances, provide improved traction, improved wear resistance and improved structural support for the trailer floor. In some embodiments, for example, the cutout portion 104 covers a high percentage of the top surface 120 of the elongated member 102 (for example, about 80 percent of the top surface 120). As such as, the insert 106 may also cover a high percentage of the top surface 120 of the trailer floor. As a result, cargo that is placed on the trailer floor contacts mostly the top surface 132 of the inserts 106, which has increased traction and increased wear resistance.
The top surface 120 of the inserts 106 may also have a high coefficient of friction. Thus, in some embodiments the apparatuses 100 that form the trailer floor provide increased traction for objects placed on the trailer 200. For example, in some embodiments, a user may drive a backhoe or other piece of construction equipment onto the trailer floor when the trailer floor is inclined, such as on a dovetail trailer or a kneeling trailer. The increased traction of the top surface 132 of the inserts 106 provides increased traction to prevent the tires of the backhoe from slipping while driving up an inclined surface of the trailer 200. The increased traction of the top surface 120 of the inserts 106 may also assist in wet conditions, including when the apparatuses 100 are used as the flooring of an outdoor scaffolding.
In addition, in some embodiments the increased wear resistance of the top surface 132 of the inserts 106 may guard against wear and deterioration if the trailer 200 is left outside for long periods of time. As such, the trailer 200 may remain intact and/or aesthetically pleasing for a longer period of time when compared to trailers made with other flooring materials.
As described above, in some embodiments at least a portion of the top surface 120 (
In addition, in those embodiments in which the cutout portion 104 does not cover the entire top surface 120 of the elongated member 102, an object on the trailer 200 contacts both the insert 106 and the top surface 120 of the elongated member 102 simultaneously. Thus, forces applied to the apparatus 100 by the object on the trailer are applied simultaneously to the insert 106 and the top surface 102 of the elongated member 102. In some embodiments, this reduces the chance that the insert 106 may be torn from the cutout portion 104.
In some embodiments, the apparatuses 100 are sufficiently strong that the trailer 200 requires fewer intermediate frame members 206 to support a particular object on the trailer 200. Thus, in some embodiments the cost to build the trailer 200 and the overall weight of the trailer 200 can be reduced when using the apparatus 100.
While the attachment mechanism 130 shown in
As shown in
While the above description illustrates the use of the apparatus 100 on a trailer 200, the apparatus 100 can also be used as a flooring element for many other types of floors and support structures. For example, the flooring apparatuses 100 can be used as the flooring for a deck of a home, as a safety flooring material for an industrial application, such as an offshore drilling rig, as a material for steps of a staircase, or as flooring on scaffolding, walkways or other elevated pathways. One of skill in the art will recognize other suitable uses for the apparatus 100.

A cutout portion 104 is then created in the top surface 120 of the elongated member 102, as provided at block 306. In some embodiments, the cutout portion 104 is made by milling a portion of a wooden elongated member 102. As described above, the cutout portion 104 may extend the entire length of the elongated member 102 or may extend less than the entire length of the elongated member 102. The elongated member 102 may include any number of cutout portions 104 and the cutout portions 104 may extend perpendicular to, parallel to, or at another angle with respect to the longitudinal axis 108 of the elongated member 102.
The method 300 may also include securing one or more inserts 106 at least partially within the cutout portion 104, as provided at block 308. The inserts 106 may be created by extruding a rubber material, cutting a material from a large, pre-formed sheet of the material, molding a material, or any other suitable forming process or combination of processes. In some embodiments, for example, the insert 106 is made from rebonded rubber (i.e., rubber that has been recycled using heat, pressure and a urethane bonding agent) which, in some embodiments, includes one or more pigments to produce an insert 106 of a particular color. In some embodiments, the rebonded rubber material is formed into sheets that are then cut into the shape of the insert 106. In some embodiments, surface texture is also added to the surfaces of the insert 106, for example, by stamping a texture onto the surfaces of the insert 106. In some embodiments, a pigment or other coloring agent is applied to the inserts 106, included in the raw materials used to make the inserts 106 or otherwise incorporated into the inserts 106 to give the inserts 106 a desired color. In some embodiments, the color of the inserts 106 matches the color of the elongated member 102, while in other embodiments the color of the inserts 106 does not match the color of the elongated member 102.
The inserts 106 may be fixed in the cutout portion 104 by inserting an adhesive 126 between the inserts 106 and the cutout portion 104, as provided at block 310. In some embodiments, the inserts 106 may also be secured to the cutout portion 104 by applying one or more mechanical attachment mechanisms to the insert 106 and the elongated member 102, such as, for example, nails, screws or bolts.
Referring now to
The method 400 may also include providing a plurality of elongated members 102 that include a top surface 120 that has a cutout portion 104 and an insert 106, as provided at block 406. The elongated members 102 may be secured to the intermediate frame members 206, the first and/or second frame members 202 and 204, and/or any other portion of the trailer 200 by any suitable attachment mechanisms, such as for example, mechanical fasteners such as bolts, screws or nails, as provided at block 408. Each elongated member 102 may be spaced from the adjacent elongated members 102 or may be placed directly adjacent to other elongated members 102. In some embodiments, an end of the elongated members 102 may be sealed, for example, by securing an end cap 144 on the end of the elongated member 102. In some embodiments, a first elongated member 102 may be aligned with a second elongated member 102 (i.e., an end-to-end alignment) if the elongated members 102 are not be long enough to cover the trailer 500. As described above, the first end 138 of the first elongated member 102 may include a recess 136 and the second end 140 of the second elongated member 102 may include a protrusion 142 that is configured to fit within the recess 136.
