Definitions
- a variety of structural arrangements are currently utilized in automotive vehicles for fixing in position the power, suspension and payload-bearing components relative to each other.
- Such structural arrangements in some contexts referred to as the vehicle’s chassis, range from a ladder chassis design, in which components are by and large secured to robust metallic beams running longitudinally and transversely underneath the vehicle, to a monocoque design, where there is not any structure specifically tasked to secure load components, but instead the vehicle’ s skin performs that function.
- a structural arrangement arguably intermediate between the ladder chassis and the monocoque design is in the form of a tubular exoskeleton, sometimes referred to as a space frame.
- the exoskeleton/space frame employs a number of tubular members fastened to each other and arranged to form a three dimensional skeleton- like structure that distributes compressive, bending and torsional loads somewhat in the manner of a monocoque design, yet provides multiple discrete regions for securing load components, in the manner of a ladder frame (although to a greater extent).
- the exoskeleton/space frame is often employed for limited production vehicles, due to it high performance and relative ease of manufacture.
- Chassis tabs generally are metallic pieces, cut from plate stock, sometimes bent to shape and/or drilled to accept a bolt, and then welded to the tubular members at discrete locations.
- chassis tabs are labor-intensive to install, being subject to movement or creep during installation.
- chassis tabs create localized areas of stress and are known to break, and are unsightly and potentially hazardous if left on the tubular member in the event a component is relocated to another position.
- the present inventions provide chassis anchoring systems that are easy to install and strong, and which permit removal and relocation of vehicle components without leaving behind vestigial protrusions as in the case of chassis tabs.
- the subject inventions are not subject to movement or creep during installation, and do not induce localized stress areas in the manner of chassis tabs.
- the subject inventions can increase the strength in the anchoring region, and, when used to secure vehicle components to tubular structural members, distribute the force transferred to both sides of the member.
- the inventions described herein have utility in securing active components to a vehicle’s chassis, such as shock absorbers, suspension and brake arms and linkages, door and compartment hinges and the like.
- the present invention is directed to an anchor assembly for attachment to a tubular member having an exterior surface, where the assembly comprises an anchor base and first and second opposed spaced-apart anchor cheek members extending from the anchor base, and where the anchor cheek members are adapted to secure a load-bearing vehicle component.

- the interior skirt has a second pair of spaced-apart opposed cut-outs, with each of the second pair of cut-outs having a shape that generally conforms to the shape of the exterior surface of the tubular member.
- the assembly further comprises a boss having a first flanged end and a second end, where the boss is adapted to be positioned in first and second apertures in the exterior surface of the tubular member with the flanged end in contact with the first aperture and the second end accessible through the second aperture; and a fastener connected to the anchor base and the second end to secure the anchor base to the boss.
- the invention is directed to a two-position anchor assembly for attachment to a tubular member having an exterior surface, where the assembly comprises an anchor base and first and second opposed spaced- apart anchor cheek members extending from the anchor base, and where the anchor cheek members are adapted to secure a vehicle component.
- the anchor base comprises a load-bearing exterior skirt and a load-bearing interior skirt circumscribed by the exterior skirt, where the exterior and interior skirts are dimensioned to be in contact with the exterior surface of the tubular member when positioned against it;
- the exterior skirt has first and second pairs of spaced- apart opposed cut-outs, with the first pair being approximately perpendicular to the second pair, and with each of the cut-outs of the first and second pairs of cut outs having a shape that generally conforms to a shape of the exterior surface of the tubular member;
- the interior skirt has third and fourth pairs of spaced- apart opposed cut-outs, with the third pair being approximately perpendicular to the fourth pair, and with each of the cut-outs of the third and fourth pairs of cut outs having a shape that generally conforms to the shape of the exterior surface of the tubular member.
- the assembly further comprises a boss having a first flanged end and a second end, where the boss is adapted to be positioned in first and second apertures in the exterior surface of the tubular member with the flanged end in contact with the first aperture and the second end accessible through the second aperture; and a fastener connected to the anchor base and the second end to secure the anchor base to the boss.

- anchors 230, 250, 260, 270 and 360 (described below) to the tubular member of a vehicle chassis are described below with respect to general purpose anchor 230, although the description equally applies to anchors 250, 260, 270 and 360 as well.
- tubular member 16 To secure general purpose anchor 230 to exemplary tubular member 16, a portion of which is shown in Figure 6, two opposed circular tube apertures 281, 282 are formed in tubular member 16. Apertures 281, 282 are generally orthogonal to the axial centerline 283 of member 16, as shown in Figure 6 (Angle A is approximately 90°), and are located along a diameter B ( Figure 6) of tubular member 16.
- Figures 5A and 5B depict an anchor securing element, boss 290, which is a cylindrical member inserted through apertures 281, 282 shown in Figure 6.
- Boss 290 has a shaft 291 that terminates in a flanged end 292.
- the length and diameter of boss 290 can be varied in accordance with the particular application for which it is used. As a general design rule, the length of shaft 291 should be approximately the same as, or greater than, the outside diameter of tubular member 16, such that it extends through tubular member 16 when inserted through apertures 281, 282 and the flanged end 292 is positioned against the outer surface of tubular member 16.
- countersinks 253 are provided so that anchors 230, 250, 260 and 270 can sit flush against the surface of tubular member 16 in the event the end of shaft 291 distal from flanged end 292 protrudes beyond the surface of tubular member 16 when boss 290 is inserted through apertures 281, 282.
- the end of boss 290 distal from flanged end 292, stepped end 293, preferably has a reduced diameter as compared to the diameter of shaft 291 between flanged end 292 and stepped end 293.
- the diameter of tube aperture 281 preferably is smaller than the diameter of tube aperture 282. Further, it is preferred that the diameter of shaft 291 between flanged end 292 and stepped end 293 be greater than the diameter of tube aperture 281 and slightly less than the diameter of tube aperture 282, and it is preferred that the diameter of stepped end 293 be slightly less than the diameter of tube aperture 281.
- boss 290 is self aligning; i.e., boss 290 can be inserted into apertures 281, 282 from one direction only, and only up to the point where flanged end 292 comes into contact with the surface of tubular member 16. Therefore, utilizing a self-aligning anchor securing element, which in the preferred embodiment is boss 290 with the design features disclosed herein, facilitates component assembly and provides a measure of quality control during component assembly. [0064] It is preferred that boss 290 be welded in place to tubular member 16, at flanged end 292 and at stepped end 293, to permanently fix it in place.
- boss 290 can be left unsecured to tubular member 16, relying on flanged end 292 to maintain it in proper position until the anchor/boss assembly is secured into place.
- boss 290 In an alternative embodiment of boss 290, flanged end 292 and stepped end 293 are omitted, such that shaft 291 of boss 290 is of generally uniform diameter along its length.
- apertures 281, 282 can have the same diameter, sized to received shaft 291.
- Boss 290 in this alternative embodiment can then be inserted into tubular member 16 through either of apertures 281, 282. Given the omission of flanged end 292 in this embodiment, it is preferable to permanently fix boss 290 in place, as by welds at one or both of apertures 281, 282.
- Boss 290 also has a bore 294 for receiving a removable fastener 295 , such as a threaded bolt.
- Bore 294 can be threaded or smooth. If bore 294 is threaded, fastener 295 should be correspondingly threaded to permit fastener 295 to be secured tightly to boss 290. If bore 294 is smooth, fastener 295 should be of a length larger than the outside diameter of tube 16, such that when inserted in bore 294, the portion of fastener 295 protruding beyond tube 16 can be secured, such as by threading the protruding portion and securing it with a corresponding nut.
- Accessory anchor 360 differs from anchors 230, 250, 260 and 270 in that anchor 360 is secured to two opposing sides of a tubular member.
- accessory anchor 360 includes a support yoke 361 having two opposed fastening mounts 363, mounts 363 each defining an annular mounting aperture 364.
- the distance between fastening mounts 363 preferably is slightly greater than the cross-sectional width of the tubular member to which anchor 360 will be fastened, so as to provide a removable yet snug fit between the tubular member and accessory anchor 360.
- Anchor 360 is to be fastened to a tubular member received in support yoke 361 and can be secured using apertures 364 and a removable fastener 295, preferably utilizing the Securing Elements described above.
- a boss 290 and a fastener 295 are illustrated in their proper positions in Figures 7A, 7C and 7D.
- An integral lock nut 365 is optionally provided to which fastener 295 can be secured.
- Support yoke 361 is joined to a support stmt 369, which has two opposed generally planar anchor faces 364, each approximately parallel to the other.
- Support stmt 369 is joined to an accessory mounting surface 366 distal from support yoke 361, as shown for example in Figure 7A.
- Accessory mounting surface 366 defines two accessory mounting apertures 367 (e.g., Figures 7C and 7D), which are shown in the figures provided with accessory mounting bolts 368 for illustrative purposes.
- support yoke 361 preferably has a generally ring-shaped configuration, the inside diameter of which preferably is slightly greater than the outer diameter of tubular member 16 so as to provide a removable yet snug fit between accessory anchor 360 and tubular member 16.
- support surface 362 has a width (measured in the axial direction of the tubular member) that is sufficient to resist any anticipated bending loads on accessory anchor 360.
- Support surface 362 can be shaped so that support stmt 369 either is orthogonally disposed relative to the surface of the tubular member to which anchor 360 is fastened, or is inclined at a select non-orthogonal angle relative to that tubular member surface.
- support surface 362 is oriented so that support stmt 369 is inclined at an angle oq relative to the surface of tubular member 16, where angle ai is less than 90 degrees.
- accessory mounting surface 366 optionally can be curved or shaped as desired to accommodate the particular accessory to which it is to be fastened.
- mounting surface 366 can be inclined relative to support stmt 369 in one or two directions.
- mounting surface 366 is inclined at an angle a 2 relative to support stmt 369.
- Angle ai can be approximately equal to angle a 2 , or can differ from angle a 2 , in accordance with usage considerations.
- angle oq is approximately equal to angle a 2 .
- Accessory anchor 360 is useful for securing a wide variety of vehicle components and accessories to a tubular member, such as vehicle radiators.
- boss 290 is utilized herein to fasten anchors 230, 250, 260, 270 and 360 to a tubular member
- boss 290 can also be utilized to fasten vehicle components directly to an appropriate member of an automotive chassis without utilization of anchors 230, 250, 260, 270 or 360, as the situation may admit.
- boss 290 and associated supporting elements can be utilized to secure gearbox hanger plates directly to an exoskeleton/space frame chassis, which gearbox hanger plates facilitate the mounting of a gearbox to the chassis, and which are disclosed in U.S. Provisional Application No. 62/577,965 entitled “Invertible Reversible Multi-Application Gearbox,” filed Oct. 27, 2017, and in U.S. Patent Application No.
- boss 290 and associated supporting elements also can be utilized to secure gearbox hangers directly to an exoskeleton/space frame chassis, which gearbox hangers facilitate the mounting of a gearbox to the chassis and which are disclosed in U.S. Provisional Patent Application No. 62/616,601 entitled“Gearbox Mounting System,” filed January 12, 2018, and in U.S. Patent Application No. 16/168,978, filed Oct. 24, 2018, entitled“Gearbox Mounting System,” each having the same inventors as the subject application.
