Title: Vehicle bicycle carrier with rotating post

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This Application claims the benefit of and priority to U.S. Provisional Patent Application No. 62/945,673, filed on Dec. 9, 2019, titled “VEHICLE BICYCLE CARRIER WITH ROTATING POST”, the contents of which are expressly incorporated herein by this reference as though set forth in their entirety. 
    
    
     FIELD OF USE 
     The present disclosure relates generally to vehicle racks and, in particular, to a vehicle rack for bicycles that has a rotating post. 
     BACKGROUND 
     Bicycles may generally be secured to a vehicle through various racks and carriers. One type of rack that is mounted to a vehicle is the hitch mounted carrier (sometimes referred to as a rack). The bicycle may be attached to the rack by either hanging them on supporting arms or securing them in such a manner that their tires rest on a tray or an equivalent platform type of device. There are numerous ways and devices to secure the bike on the tray, one of which is to use a clamp that may hold the bike by either its frame or seat post. Due to the wide variety of bicycles on the market, which now includes electric bikes, there often is no simple or common locations to attach the clamp to the bike. In the case of electric bikes, frames often have batteries attached to them, and many bikes use a shock absorbing seat post making the seat post unable to accept a clamp. Therefore, the clamp must be free to secure the bike&#39;s frame in different places or should be generally available to secure the seat post. This can be accomplished via a long, solidly mounted ‘clamping frame’ that may be parallel to both the bike and the rear of the vehicle. In this manner, the clamp may have multiple, slidable positions. One useful feature of some carriers is the ability to fold upward and/or flat against the rear of the vehicle when not in use. To fold the carrier flat against the vehicle, the clamping frame must also be folded, removed, or moved so as not to interfere or make contact with the vehicle when the carrier is put into the folded position. 
     U.S. Published Patent Application No. 2007/0108245 discloses a non-folding bike carrier with the clamping frame located at the front of the carrier. The bike closest to the frame usually has no difficulty getting the clamp into a desired position, but the outer bike&#39;s clamp may have interference issues due to the presence of the first bike. This deficiency may be resolved by placing the clamping frame between the two bikes. 
     U.S. Pat. No. 6,019,266 discloses a center mounted clamping post with slidable clamps located between the bikes. Other prior systems disclose that the center post can be rotated sideways to facilitate bike carrier foldup against the rear of the vehicle. However, the disadvantage with the single post design (or narrow U-frame design) is that the slidable clamps are restricted to vertical motion only, greatly limiting available clamping locations. The bike can be laterally repositioned for a better clamping location, however, this may cause the bike&#39;s front or rear wheel to extend beyond the width of the vehicle, especially if mounted to a narrow automobile. 
     U.S. Pat. No. 8,235,267 discloses a carrier with a center inverted “U-frame” that can pivot sideways and can fold flat against the vehicle. This carrier utilizes sliding hooks to “press” the bike frame down into the wheel trays, rather than a clamp to grab the frame or seat post. When using sliding hooks to hold down the bike, there is no mechanical need for multiple “press down” locations, because the hook will make contact with the bike&#39;s top tube (or top tube adapter for step-thru style frames). The disadvantage of the “press down” hook is that they do not always work with certain types of bikes, such as electric bikes. For those applications, the frame/seat post clamp would be necessary. 
     Most bike carriers currently on the market using the U-shaped clamping frame located between the bikes have a clamping frame width of approximately 18″ to 30″. This allows for a wide range of clamping locations. To deploy the bike carrier to a folded position flat against the vehicle, the clamping frame must be either removed or folded out of the way. With the clamping frame parallel to the rear of the vehicle, the clamping frame must rotate forward, so it is lying on top of the trays. Functionally, this allows the bike carrier to be deployed to its folded position flat against the vehicle, however, the clamping frame may extend 24″ to 36″ above the tray when the bike carrier is folded. This is functionally, visibly, and esthetically inconvenient. 
     Thus, what is needed is a bike carrier rack wherein the clamping frame can be rotated at least 90 degrees from parallel to perpendicular to the rear of the vehicle and then hinged down so it is lying above or on top of the wheel trays, which then allows the bike carrier to be deployed to a folded position flat against the vehicle. Before the device of the present disclosure no system has featured a rotating post. 
     SUMMARY 
     The following presents a simplified overview of the example embodiments in order to provide a basic understanding of some embodiments of the example embodiments. This overview is not an extensive overview of the example embodiments. It is intended to neither identify key or critical elements of the example embodiments nor delineate the scope of the appended claims. Its sole purpose is to present some concepts of the example embodiments in a simplified form as a prelude to the more detailed description that is presented hereinbelow. It is to be understood that both the following general description and the following detailed description are exemplary and explanatory only and are not restrictive. 
     One embodiment may be a trailer hitch mounted automotive bike carrier with bicycle wheel supporting trays and the ability to hold the bicycle at various locations of its frame or seat post with a clamp. The clamp may be slidably attached to a U-shaped clamping frame located between the bikes, the clamping frame may be of round tubing parallel to the rear of the vehicle. When the bikes are not mounted for transport, the clamping frame is rotated 90 degrees so as to be perpendicular to the rear of the vehicle and fold down so as to be resting on or above the bike carrier&#39;s wheel trays. The bike carrier can then be deployed to a stowed position against the rear of the vehicle. When the clamping frame is rotated 90 degrees then folded down, and the bike carrier deployed to its folded position, the vertical tubes of the clamping frame can be positioned very close to (and potentially matingly engaged with) the carrier&#39;s wheel trays, allowing for a more streamlined and attractive stowed appearance. It also allows for a smaller required area when not in use and stored in a garage or the equivalent. 
     In one embodiment, the sequence of steps to bring the carrier from a bike transporting position to a stowed position may be:
     1. Remove the bicycle from the carrier,   2. Unlock and rotate the clamping frame (approximately 90 degrees) from the parallel (to the rear of the vehicle) orientation (or position) to the perpendicular (to the rear of the vehicle) orientation (or position)   3. Lock the clamping frame into the perpendicular position   4. Unlock and hinge the clamping frame down (approximately 90 degrees) so that the clamping frame is in a folded position above and parallel to the wheel support tray   5.

       FIG. 1  is an illustration of a perspective view of one embodiment of the vehicle rack with a rotating post. As shown in  FIG. 1 , the vehicle rack  100  may comprise a carrier base  120 , a carrier fold-up bracket  103 , a clamping frame base hinge/bracket  104 , and clamping post  107 . The parts of the vehicle rack may be made from a strong material, such as steel, iron, or aluminum. The carrier base  120  may be configured to support and engage with a load, such as one or two bicycles. The carrier base may comprise wheel support trays  101 ,  102 , and a wheel support beam  128 . As shown the wheel support beam  128  may extend distally away from the vehicle to which the vehicle rack  100  is configured to engage. The wheel support beam  128  may be attached (permanently (such as through welding) or removeably (such as using bolts) to the wheel support trays  101 ,  102 . As shown, the carrier base  120  is configured to, in a balanced manner, support one or two bicycles by engaging the tires of the bicycles. 
     The wheel support beam  128  may be connected (preferably permanently via welding) to the carrier foldup bracket  103 , such that when the carrier base is put into a stowed position, the wheel support beam  128  moves with the carrier foldup bracket  103  as it hinges upward. The carrier foldup bracket  103  may be connected to the hitch stinger  132  via pivot bolt  129 . The carrier foldup bracket may further comprise stowed position lock  130  and in-use position lock  131 . As shown the in-use position lock  131 , which may be a spring-loaded pull knob pin, may lock the wheel support beam  128  into an in-use position. When the user wants to fold up the vehicle rack, the user may pull out the knob of the in-use position lock  131 , which may allow the carrier fold up bracket  103  to hinge upward with respect to the hitch stinger  132 . Once in the folded-up position (stowed position), the user may lock the carrier into the stowed position by engaging the stowed position lock  130 , which may also be a spring-loaded pull knob pin. The hitch stinger  132  is configured to slide into the trailer hitch receiver  127 , which may be attached to the vehicle. The hitch stinger  132  and the trailer hitch receiver  127  may be locked together via a pin or via a spring/push latch. 
     The carrier base  120  may preferably be attached to the post base hinge/bracket  104 . This attachment is preferably a permanent attachment, such as through welding. The post (or clamping frame) base hinge/bracket  104  may be hingedly attached to the clamping post  107 , such that clamping post  107  may have an in-use (up right) position and a stowed (folded down) position. 
     The clamping post  107  may comprise a clamping post housing  108 , which may be configured to be the base of the clamping post  107  and may directly engage with the clamping frame base hinge/bracket  104 . The clamping post  107  may further comprise rotating post base  109  and clamping frame assembly  105 . The clamping frame assembly  105  may comprise clamping tube  106  and one or more bike engagement portions  199 . Although a U-shaped clamping tube  106 , as shown, is preferred (because it allows the bike engagement portions to be easily slid along an entire length), any shape may be used, including circular, rectangular, or a single rod/post. As shown, the bike engagement portions  199  may comprise frame clamp adapter  135 , a bike clamp position tube  136 , a bike clamp  133 , and a tightening knob with bolt  134 . Preferably, each bike clamp  133  is configured to engage a bicycle that is loaded onto the rack  100 . The frame clamp adapter may be configured to releaseably hold the bike engagement portion  199  on to the clamping tube  106 , such that the bike engagement portion  199  may be positioned and re-positioned along the length of the clamping tube  106 . The tightening knob with bolt  134  may allow the user to engage and disengage the bike clamps  133 . 
       FIG. 2  is an illustration of a perspective view of one embodiment of the vehicle rack showing the post base hinge/bracket. As shown in  FIG. 2 , the clamping post base  108  may preferably fit into clamping post housing  108  and be locked in place by post lock  110 . Post lock  110  may be a spring-loaded pull knob pin, but may be any mechanism that that releasably locks the post base  108  into the housing  109 , may be used, including an L pin. Although the post base  109  and the clamping tube  106  are shown as two separate pieces of the clamping frame assembly  105 , it should be understood that the clamping frame assembly  105  may be a unitary structure and may be of any shape that allows it to engage with and/or secure one or more bikes. 
       FIG. 2  also shows that the clamping post  107 , via clamping post housing  108 , may hingedly connect to clamping frame base hinge/bracket  104  at pivot bolt  116 . Pivot bolt  116  essentially acts as a hinge pin at which the clamping post may hinge up or down relative to clamping frame base hinge bracket  104  and carrier base  120 . As shown the post  107  may be locked into an in-use position by L pin  113  going through hole for in-use position  115 . In some embodiments, the L pin  113  may be a spring-loaded pull knob pin. When the L pin  113  is removed, the post  107  may hinge down into a stowed position and then locked into this stowed position via the L pin  113  going through the hole for stored position. The clamping post housing  108  may have a hold or notch that the L pin  113  is also engaging with when the post is locked into the stored or in-use positions. 
       FIG. 3  is an illustration of a perspective view of one embodiment of the vehicle rack with a rotating post that is attached to a vehicle and is ready to receive and engage a load.  FIG. 3  shows that the vehicle rack may be engaged with a vehicle  300  and may be configured to securely hold one or two bikes.  FIG. 3  shows that the clamping frame assembly may be in a parallel (to the vehicle  300  and the wheel support trays  101 ,  102 ) configuration when it is ready to engage with the bikes.  FIG. 3  also shows how the bike engagement portions have been moved to a different location on the clamping frame assembly  105 . 
       FIG. 4 a    is an illustration of a perspective view of one embodiment of the clamping post of a vehicle rack.
