1. Field of the Invention
This invention relates generally to vehicle wheel covers, and more particularly to a commercial display wheel cover including a quick disconnect mechanism permitting convenient wheel lug nut retorqueing and a replaceable display disc which remains substantially stationary with respect to the vehicle while the vehicle is moving.
2. Description of Related Art
The central outer portion of a vehicle wheel, being fully viewable while the vehicle is in motion, provides an opportunity for the placement of readable graphics in this otherwise merely decorative or unornamental portion of the wheel of larger utility vehicles such as buses or trucks. The utilization of this otherwise merely unadorned space is contingent upon the readability of graphics and word messages being held relatively stationary with respect to the vehicle in motion. A number of prior art patented inventions address this display and advertising opportunity.
In U.S. Pat. No. 5,659,989, Hsiao teaches a wheel cover which includes an outer disc member which is rotatably mounted to an inner base member so that the display indicia applied to the disc member will remain substantially rotation free under vehicle movement. This disclosure includes stabilizing structure to maintain alignment and restrict oscillation of the outer disc member bearing the viewable indicia thereon.
Boothe, in U.S. Pat. No. 5,957,542 discloses a theft-proof, non-rotational wheel cover with replaceable ornamental outer surface. This arrangement relies upon and is engageable within the central cavity of the automotive wheel.
Another advertising display device for a vehicle wheel is disclosed by Ryan in U.S. Pat. No. 2,548,070. In this arrangement, however, the device is adapted for attachment to a non-rotatable axle of the motor vehicle.
In U.S. Pat. No. 2,869,262, Lucas teaches another wheel-supported advertising sign arrangement which appears to attach in rotatable fashion to the outer hubcap of the wheel assembly.
In the disclosure of Kovalenko, in U.S. Pat. No. 4,280,293, a stationary display member is attachable to the vehicle hub and utilizes a flowable material such as mercury acting upon veins within a chamber of the device to substantially eliminate rotation of the bearing-mounted outer display member.
A non-rotating wheel cover assembly shown in U.S. Pat. No. 5,588,715 invented by Harlen teaches yet another wheel cover assembly which is attachable to the outer end of an axle by separate bracketry to support the bearing mounted display member. A thickened lower portion of the wheel cover provides sufficient counterbalance to inhibit or prevent rotation of the display cover while the vehicle is in motion.
Matsushita discloses a free wheel cap in U.S. Pat. No. 4,678,239 which teaches a non-rotating wheel cover having a counterbalanced disc-like body which is bearing connected to an inner multi-arm structure having spring-like clips connected at the outer periphery of the device which interengage with the wheel rim.
Another wheel cover was invented by Okamoto and disclosed in U.S. Pat. No. 6,120,104 teaching a flexible side feature connected to the center of the wheel in support of a display wheel cover. An air current guide is formed into the display cover which assists in stabilizing the display portion without substantial rotational movement as the vehicle is moving.
Other prior art devices which teach vehicle wheel display covers are as follows:
U.S. Pat. No. 6,536,848 discloses a display wheel cover which is substantially non-rotating with respect to the vehicle when in motion and which, in a preferred embodiment, utilizes a unique inner member having an elongated hat-shaped section that facilitates attachment to the rim of the wheel by threadably adjustable rim-engaging members that align into the concave groove formed in the outer wheel rim. A unique cam-locking device both retains the outer display wheel cover in place and also prevents its theft removal as a separate security feature requiring a special tool for removal.
This invention is directed to a display wheel cover assembly uniquely connectable to, and removable from, a rotatable wheel of a vehicle. This invention includes an adapter plate releasably connectable by unique replacement lug nuts to the outside of the wheel serving as combination spacers and lug nuts. A support bearing member is connected coaxially with a hub of the adapter plate. A wheel cover including a key-actuated locking support having a coaxially extending support shaft is rotatably supported in the support bearing member. An elongated cylindrical locking member is positioned within a longitudinal aperture formed through the support shaft, while a cam member, connected to a distal end of the locking member, has a non-symmetric periphery such that, when properly rotatably orientated, is fully insertable into said support bearing member. In a second rotational orientation, the cam member prevents withdrawal of the support shaft from the support-bearing member. A counterweight attached to the wheel cover prevents rotation of the wheel cover. Interchangeable display indicia attach to the wheel cover.
It is therefore a broad object of this invention to provide a non-rotating wheel cover for a commercial utility vehicle or truck which will facilitate the application of decorative and readable commercial display indicia such as in advertising while the vehicle is moving.
It is yet another object of this invention to provide an advertising display cover for the wheel of a commercial vehicle which is easily interchangeable and which is rendered secure from inadvertent or theft removal by a unique locking arrangement.
Still another object of this invention is to provide an advertising display cover for the wheel of a vehicle which receives support from the lugs of the axle of the vehicle through the use of uniquely configured double-duty wheel lug nuts serving as spacers and lug extensions.
Yet another object of this invention is to provide an advertising display cover for the wheels of commercial vehicles which is easily removable to facilitate regular servicing and tightening of the unique lug nuts which hold the wheel onto the axle and also support the wheel cover.
In accordance with these and other objects which will become apparent hereinafter, the instant invention will now be described with reference to the accompanying drawings.
Referring now to the drawings, and particularly to FIGS. 1 to 9, one broad aspect of the invention is there shown generally at numeral 10 in
Attachment of the adapter plate 12 to a rim R of a wheel for a vehicle about the axle center line D is effected through the use of a uniquely configured lug nut 22. As best seen in
The adapter plate 12 includes a central dish-shaped area 14 supporting the hub 28 which supports the bearing arrangement 16 as previously described. A mounting flange 54, offset and radially extending from the central area 14, has threaded mounting holes 52 which provide the attaching means through aligned holes 50 adjacent the periphery of retainer plate 20 by conventional threaded fasteners (not shown for clarity).
Also disposed on the central area 14 is a plurality of apertures 32 each having a partial cover 30 defining an interior cavity 34 associated therewith. The diameter of the mounting apertures 32 is sized for close snug fitting over the distal head 26 of each of the lug nuts 22. The cylindrical cavity 34 is also similarly sized as a uniform extension of mounting aperture 32 to receive the head 26 as best seen in
The retainer 18 receives support for rotation by the close sliding alignment of the central aperture 56 over hub 28. The retainer plate 20 is, as previously described, attached to the outer flange 54 of the adapter plate 12 by threaded fasteners through aligned holes 50 and 52. The retainer 18 is attached at threaded cavity 42 to the retainer plate 20 by a threaded fastener 44 fitted through elongated slot 46 of the retainer plate 20. As will be described herebelow, the retainer 18 is thus held for very limited rotational movement about axis D when fastener 44 is loosened as limited by the elongated slot 46, the purposes of which will be described herebelow.
The retainer 18 also includes a plurality of spaced radially extending locking tabs or fingers 38 which are laterally offset from the central portion 40 of the retainer 18. Tabs or fingers 38 are spaced rotationally about axis D to be identical to (or matching) the rotational spacing of each of the mounting apertures 32 and corresponding lug nuts 22. Again, for economy, only three such combinations of lug nuts 22, mounting apertures 32 and fingers or tabs 38 are provided as being deemed sufficient for attachment of this entire arrangement 10 to the rim R as previously described.
With this arrangement 10 assembled onto the rim R as previously described, the retainer 18 may be rotated about axis D only very limited amount as permitted by slot 46 when the threaded fastener 44 is loosened. Movement of this retainer 18 is between an unlocked and a locked position with respect to the retention or release of the adapter plate 12 with respect to the lug nuts 22 and the heads 26 thereof. As seen in
To release or unlock the adapter plate 12 from the lug nuts 22, threaded fastener 44 is simply loosened and then may be utilized to rotate the retainer 18 in the direction of arrow B in
Referring now to
To accommodate this axle hub M arrangement, a shortened elongated attaching lug 22′ is provided. This attaching lug 22′ has a first end 24′ which is threaded similar to lug N and is threadable into the threaded cavities H′ of the axle hub M. Typically, there are eight or ten such lugs N utilized to assemble the axle hub M and it is thus preferred to replace only a portion (typically three) of those standard lugs N by the attaching lugs 32′ to provide adequate strength. As previously described, after the attaching lugs 22′ are installed into the portion of the threaded holes H′, the hreaded opposite ends 26 of the attaching lugs 22′ are passed through the mounting holes 32 and thereafter, into locking engagement within cavities 34.
Once the adapter plate 12 is lockingly secured to the lug nuts 22 by the retainer 18 and retainer plate 20, the outer commercial display wheel cover 130 as seen in FIGS. 10 to 12, may then be installed. The wheel cover locking support 100, as shown in detail in FIGS. 13 to 18, is provided to effect installation of the wheel cover 130. The wheel cover locking support 100 includes an elongated support shaft 104 and an enlarged orthogonally extending mounting flange 102 having threaded attaching apertures 138 which are aligned with apertures 136 of the wheel cover 130 as seen in
The locking or anti-theft features of this invention include an elongated locking member 106 which snugly and slidably engages for rotation within an elongated aperture or passageway formed longitudinally through the support shaft 104. Note importantly that the separate axis E of the elongated locking member 106 and mating passageway are offset and parallel to the longitudinal axis D which is concentric with the outer cylindrical surface of the support member 104, the rim R and the vehicle axle.
A cam member 120 is mechanically attached by a threaded nut 122 onto the distal end of the support shaft 104. A detent plunger 114 is biased by spring 118 to act within an arcuate cavity 142 of actuator 110 which is engaged over the head 108 within mating cavity 124 of locking support 100. Relative axial rotation of the support shaft 104 is thus limited by the sliding movement of the detent plunger 114 within the arcuate cavity 142. When in the position shown in FIGS. 14 to 16, the detent plunger 114 is urged into a locking cavity 112 formed at one end of the arcuate groove 142. This locked position coincides with the cam member 120 being misaligned at 154 as best seen in
When the locking member 106 is rotated into the position shown in FIGS. 17 to 19 wherein the plunger 114 moves out of the locking cavity 112 to the opposite end of the arcuate cavity 142, the cam member 120 is precisely aligned with the cylindrical outer surface of the support member 104 whereupon the wheel cover locking support 100 may be slidably withdrawn axially from engagement within the bearing arrangement 16 or 66.
Referring additionally to FIGS. 24 to 27, a locking key 144 is there shown. This locking key 144, which includes a longitudinal body 146 and a handle 148, is shown engaged within mating cavities 156 of the adapter 110. One of the pins 150 is shown inserted into one of these cavities 156 which is aligned with locking detent cavity 112, while the other cavity receives the other drive pin 150 to effect rotation of the locking member 106. By insertion of the pins 150 into these cavities 156 when the locking member 106 is in the locked position shown in FIGS. 14 to 16, the detent plunger 114 is forced to withdraw against biased spring pressure from spring 118 from detent cavity 112 a distance sufficient to then allow rotation of the locking member 106 and the sliding movement of the detent plunger 114 along the arcuate cavity 142 to effect unlocking and removal of the wheel cover locking support 100 as previously described.
Referring now to FIGS. 10 to 12 and 20A to 23, a universal embodiment of the invention is there shown generally at numeral 60 in
The distinctive aspect of this embodiment 60 surrounds the universal adapter plate 62 and the associated universal retainer 68 as best seen in
This universal retainer 68 includes the disc-shaped central portion 90 having mounting aperture 92 which aligns with the threaded fastener 94 within a slotted hole formed into the retainer plate 70 as previously described. Likewise, the central hole 158 is sized to slidably receive and be supported on the central neck 78 of the universal adapter plate 62. However, this retainer 68 is provided with locking lugs or tabs 88 each of which include three separate tabs locking edge portions 88a, 88b and 88c in five separate evenly spaced arrays to match the bolt circle pattern shown in
As best seen in FIGS. 20 to 23, the universal adapter plate 62 also provides five separate clusters of three mounting apertures (not shown) formed through the central portion 64 which are sized to snugly receive the heads 76 of each of the lug nuts 72. Each of these five groups of three mounting apertures has a partial cover 80 which includes cover portions 80a, 80b and 80c. Each of these cover portions 80a, 80b and 80c provide a cylindrical interior surface which mates and is continuous with each of the mounting apertures as previously described with respect to the embodiment 12 previously described for proper stable positioning over each head 76.
