The present invention relates to a saddlebag for a motorcycle, and more particularly to a motorcycle saddlebag formed of a plurality of panels.
Motorcycle saddlebags are known for enhancing the styling and storage capacity of motorcycles. Saddlebags typically are installed on each side of the motorcycle rear fender, placing them in a prominent location that can significantly affect the overall aesthetics of the motorcycle. For this reason, one concern of motorcycle saddlebag design is that the saddlebag compliments the overall styling of the motorcycle. In this regard, when choosing saddlebag materials, designers frequently base decisions on characteristics such as the quality of the surface finish that can be obtained and the paintability of the final product. Similarly, when choosing a saddlebag manufacturing process, designers frequently base decisions on the ability of the process to efficiently create curves, arcs, and other geometry that will compliment the overall look of the motorcycle. In some cases, because of limitations associated with certain materials and the processes used to fabricate products from those materials, designers must balance the frequently conflicting requirements of obtaining a quality surface finish with good paintability against the need to achieve complex part geometries using an efficient manufacturing process.
In some aspects, the invention may provide a motorcycle saddlebag including a substantially U-shaped first panel and a substantially L-shaped second panel joined to the first panel to define a storage cavity. The first panel includes a generally forwardly-facing front portion, a generally outwardly-facing side portion, and a generally rearwardly-facing rear portion. The first panel also includes a substantially continuous outer surface extending along the front portion, the side portion, and the rear portion, and a substantially continuous inner surface opposite the outer surface. The inner surface extends along the front portion, the side portion, and the rear portion. The second panel includes a back wall and a bottom wall. The back wall defines on one end a generally forwardly-facing flange and on an opposite end a generally rearwardly-facing flange. The bottom wall defines a generally outwardly-facing flange. The forwardly-facing flange, the rearwardly-facing flange, and the outwardly facing flange are each joined to the inner surface of the first panel.
In other aspects, the invention may provide a motorcycle saddlebag including an outer panel having a forward portion, a rearward portion, and a side portion. The forward and rearward portions each curve toward and smoothly transition into the side portion. The outer panel also includes an inner surface defined by the forward, rearward, and side portions. The motorcycle saddlebag also includes an inner panel formed separately from and received by the outer panel. The inner panel includes a back portion and a bottom portion. At least a portion of the back portion extends substantially perpendicular to at least a portion of the bottom portion. The back and bottom portions cooperate to define a substantially continuous flange that is joined to the inner surface and that extends along and engages the forward portion, the side portion, and the rearward portion.
In other aspects, the invention may provide a motorcycle saddlebag including a first panel having an outer surface and an inner surface. The outer surface defines forwardly-facing, rearwardly-facing, and outwardly-facing portions of the motorcycle saddlebag. The motorcycle saddlebag also includes a second panel formed separately from the first panel. The second panel includes a back wall portion, a bottom wall portion, and a flange extending from the back wall portion and the bottom wall portion. The flange is joined to the inner surface of the first panel such that the inner surface, the back wall portion, and the bottom wall portion cooperate to define a storage cavity.
In other aspects, the invention may provide a motorcycle saddlebag having a substantially U-shaped first panel and a substantially L-shaped second panel. The first panel includes a generally forwardly-facing front portion, a generally outwardly-facing side portion, and a generally rearwardly-facing rear portion. The first panel also includes a substantially continuous outer surface extending along the front portion, the side portion, and the rear portion, and a substantially continuous inner surface opposite the outer surface and extending along the front portion, the side portion, and the rear portion. The second panel is joined to the first panel and includes a back wall and a bottom wall. The back wall defines on one end a generally forwardly-facing flange and on an opposite end a generally rearwardly-facing flange. The bottom wall defines a generally outwardly-facing flange. The forwardly-facing flange, the rearwardly-facing flange, and the outwardly facing flange each matingly engaging with the inner surface of the first panel so that the second panel may be joined to the first panel using structural adhesive.
In other aspects, the invention may provide a motorcycle saddlebag having an outer panel, an inner panel received by the outer panel, and structural adhesive joining the outer panel and the inner panel. The outer panel includes a forward portion, a rearward portion, and a side portion. The forward and rearward portions each curve and smoothly transition into the side portion. The forward portion defines a forward edge and the rearward portion defines a rearward edge. The forward portion, the rearward portion, and the side portion cooperate to define a lower edge. The first panel includes an inner surface that is at least partially bounded by the forward edge, the rearward edge, and the lower edge. The inner panel is received by the outer panel and includes a back wall and a bottom wall. At least a portion of the back wall extends substantially perpendicular to at least a portion of the bottom wall. The back and bottom walls cooperate to define a single smoothly contoured engagement surface that matingly engages the inner surface of the outer panel. The engagement surface also extends along and engages the forward portion, the side portion, and the rearward portion of the outer panel. The structural adhesive resides between the inner surface and the engagement surface to join the inner panel to the outer panel.
In other aspects, the invention may provide a method of making a motorcycle saddlebag. The method includes forming a generally U-shaped outer panel having a forward portion, a side portion, and a rearward portion. The forward portion, the side portion, and the rearward portion together define a curved inner surface. The method also includes forming a generally L-shaped inner panel including a back wall and a bottom wall. The back wall defines a generally forwardly-facing flange and a generally rearwardly-facing flange. The bottom wall defines a generally outwardly-facing flange. The forwardly-facing flange, the rearwardly-facing flange, and the outwardly-facing flange together define an engagement surface. The method further includes applying structural adhesive to at least one of the inner surface and the engagement surface, and, after applying structural adhesive, engaging the engagement surface with the inner surface to couple the inner panel to the outer panel. Engaging the engagement surface with the inner surface includes engaging the forwardly-facing flange with the inner surface at the forward portion, engaging the rearwardly-facing flange with the inner surface at the rearward portion, and engaging the outwardly-facing flange with the inner surface at the side portion.
It should be understood that the invention is not limited in its application to the details of construction and the arrangements of the components set forth in the following description or illustrated in the above-described drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
The following description is directed to embodiments of an individual motorcycle saddlebag. Directional references such as front, rear, top, bottom, left, and right, refer to the front, rear, left, and right of a motorcycle to which the saddlebag might be attached. The Figures depict a saddlebag configured for attachment to the right-hand side of a motorcycle. It should be appreciated however that saddlebags typically are provided in pairs, and that the left-hand saddlebag will in many cases be a substantial mirror-image of the right-hand saddlebag.
With reference also to FIGS. 2 and 3A-3D, the outer panel 14 is generally U-shaped when viewed from the top or bottom, and includes a generally forwardly-facing front portion 34, a generally rearwardly-facing rear portion 38, and a generally outwardly-facing side portion 42 extending between the front and rear portions 34, 38. The front portion 34 defines a forward edge 35 of the outer panel 14, and the rear portion 38 defines a rearward edge 39 of the outer panel 14. The front portion 34, the rear portion 38, and the side portion 42 cooperate to define a lower edge 43 of the outer panel 14. The outer panel 14 also includes an inner surface 46, and an outer surface 50. The inner and outer surfaces 46, 50 are both substantially smooth, continuous surfaces that extend from the front portion 34 around and through the side portion 42, and around and through the rear portion 38 of the outer panel 14. A ridge 54 extends along an upper edge of the front, rear, and side portions 34, 38, 42, and is recessed relative to the outer surface 50. The outer panel 14 defines a plurality (e.g. three, as illustrated) of mounting apertures 58 in the side portion 42. The mounting apertures 58 extend in a line substantially parallel to and slightly spaced from the ridge 54. The mounting apertures 58 are used to secure the hinge 22 to the outer panel 14. Similar apertures (not shown) are provided in the lid 18 for securing the hinge 22 to the lid 18.
Like the outer panel 14, the lid 18 also includes an outer surface 59 and an inner surface 60. The lid 18 receives the ridge 54 of the outer panel 14 when the lid 18 is closed. The ridge 54 fits inside the lid 18 to provide a smooth transition between the outer surface 56 of the lid 18 and the outer surface 50 of the outer panel 14 (see, e,g.,
With reference to FIGS. 2 and 4A-4E, the inner panel 30 includes a generally L-shaped cross-section (see
The dished portion 74 includes a forward portion 74a that defines a generally forwardly-facing flange 82, and a rearward portion 74b that defines a generally rearwardly-facing flange 86. More specifically, the dished portion 74 includes a lip 87 that extends substantially perpendicularly from the front, rear, and lower edges of the back panel 72. An interior surface 88 of the dished portion 74 extends generally outwardly from the lip 87 and is spaced from and substantially parallel to the back panel 72. The forwardly-facing flange 82 extends substantially perpendicularly from a forward portion of the interior surface 88, and the rearwardly-facing flange 86 extends substantially perpendicularly from a rearward portion of the interior surface 88. The forwardly-facing and rearwardly-facing flanges 82, 86 extend from the interior surface 88 toward and slightly beyond the back panel 72 (see
The bottom wall portion 70 of the inner panel 30 includes around its periphery a generally outwardly-facing and downwardly-extending flange 90. The forwardly-facing and rearwardly-facing flanges 82, 86 of the back wall portion 66 and the outwardly-facing and downwardly-extending flange 90 of the bottom wall portion 70 are configured to blend smoothly into one another. In this way, the flanges 82, 86, 90 cooperate to define a single, smoothly contoured engagement surface 94 that substantially corresponds to the contours of the inner surface 46 of the outer panel 14. Specifically, when the inner panel 30 is received by the outer panel 14, substantially the entire engagement surface 94 mates against the inner surface 46 of the outer panel 14. The flanges 82, 86, 90 allow the inner panel 30 to be joined to the outer panel 14 using structural adhesives or similar bonding techniques, as discussed further below. The forward and rearward portions 74a, 74b of the dished portion 74 each include a relief section 98a, 98b, respectively, to accommodate the ridge 54 of the outer panel.

The above-described exemplary configuration of the outer and inner panels 14, 30 makes the panels particularly well suited for fabrication using a combination of thermoforming methods and structural adhesive bonding. In some embodiments the panels 14, 30 and the lid 18 are formed from ABS (Acrylonitrile Butadiene Styrene) and bonded using a suitable structural adhesive, such as MA 310 two-part methacrylate adhesive, available from PLEXUS of Danvers, Mass. In other embodiments, the structural adhesive may be or include a solvent capable of at least partially dissolving some of the material along the mating surfaces of the panels such that, once cured, the panels are bonded together. One example of a solvent-based structural adhesive includes a solution of ABS dissolved in methyl ethyl ketone. While a variety of suitable materials, structural adhesives, and bonding techniques may be utilized without departing from the spirit and scope of the invention, the use of ABS as the panel material has many inherent advantages. In addition to being a low cost material, the tooling required for thermoforming operations is relatively inexpensive when compared with injection or rotational molded products. The tooling is also relatively simple to modify, if necessary, for minor design changes. The material also has a good strength to weight ratio, and a good surface finish when released from the tooling, thereby minimizing or elimination preparation of the material for painting. The use of structural adhesives and similar bonding techniques allows for relatively simple, low cost manufacturing techniques, and also enhances aesthetics by allowing for hidden bonding lines, as discussed further below.

In many applications, the bond between the outer and inner panels 14, 30 created by the structural adhesive will be stronger than the material from which the panels are fabricated (e.g., ABS). The configuration by which the flanges 82, 86, 90 are bonded to the inner surface 46 of the outer panel 14 is such that when the saddlebag 10 is coupled to a motorcycle and loaded with gear, the adhesive bonds are primarily subject to shearing loads that tend to slide the engagement surface relative 94 to the inner surface 46. This configuration generally provides superior durability when compared to other configurations in which the adhesive bonds may be subjected primarily to pealing loads that tend to pull the joined surfaces away from one another.
As illustrated, once assembled the inner panel 30 is recessed relative to the front and rear portions 34, 38 of the outer panel 14, that is, the ends of the front and rear portions 34, 38 extend beyond the inner panel 30. The side portion 42 of the outer panel 14 similarly extends generally downwardly beyond the bottom wall portion 70 of the inner panel 30. In this way, the inner panel 30 and the adhesive bonds between the inner panel 30 and the outer panel 14 are substantially completely hidden from view when the saddlebag 10 is installed on the side of a motorcycle and the lid 18 is closed. Similarly, the bracketry used to secure the saddlebag 10 to the motorcycle, which in some cases is coupled exclusively to the inner panel 30, may also be hidden from view. In some embodiments, this configuration also reduces manufacturing cost because only the outer surfaces of the lid 18 and outer panel 14 require painting and the associated paint preparation processes. The thickness of the outer panel 14 is sufficient to prevent any bond lines from “telegraphing” through to the outer surface 50.
The completed assembly of panels 14, 30 and lid 18 may also be trimmed to customize the saddlebag 10 for a particular motorcycle or motorcycle configuration. The recessed configuration of the inner panel 30 relative to the outer panel 14 provides sections of overhanging material that may be cut away after the saddlebag 10 has been assembled such that the saddlebag 10 may be customized for different motorcycles and motorcycle configurations. Although the amount of overhanging material may vary for different saddlebag designs, as shown in
