  • Patent number: 11878762
    Abstract: A universal bicycle rack with single attachment point is disclosed. The invention, referred to herein as an ‘integrated rack connection assembly’ (IRCA) is comprised of three main parts. A first part being a tubular, platform, section (PS) with crossbar members for holding user items (such as bags, cases, etc.); a second part being a Connection section (CS) for attaching the IRCA to a bicycle frame; and a third part being a tubular; platform assembly (PA) connecting the PS to the CS allowing a user to position the IRCA at various angles on a bike frame: The CS also having clamping plates allowing the apparatus to fit onto frames of different shapes and sizes. An object of the invention is to leverage the stability of a bike's central frame through a single attachment when storing items on a bicycle.

  • Publication number: 20230012876
    Abstract: A building component for building structures, the building component configured to be releasable connectable to a second conjugate building component. The building component comprises a frame being a section of a basic geometrical shape. The frame having at least one side; the side having at least a protrusion. The conjugate building component being of the same structure also has a frame having at least one conjugate side; the conjugate side having at least a corresponding conjugate receptacle. When the building component and the conjugate building component are connected the sides of building components are next to each other. The protrusion and receptacle of the components snugly engage each other so that the inner and outer surfaces of the protrusion and receptacle are in contact with each other. The friction between the surfaces prevents the disconnecting of the components.

  • Publication number: 20210315424
    Abstract: A system and method for dispensing liquid sanitizer from a wearable vessel with one hand is disclosed. The invention is comprised of a hollow, flexible vessel with a combination hinged fill cap and dispenser head as well as an external fill bottle. The wearable vessel can be worn on a wrist, arm etc. An object of the invention is to allow sanitizing liquid to be quickly available to a user at any time. Sanitizer is dispensed from the device when a user squeezes the band which dispenses small droplets of the liquid under pressure only when needed from a self-sealing aperture.

  • Patent number: 11142278
    Abstract: A tow bar assembly detachably attaches a trailer to a bicycle. The tow bar assembly has a first end having a bicycle hitch adapted to detachably attach to a bicycle, a second end having a swiveling mechanism and a connection member adapted to connect to a trailer, and an intermediate portion connecting the first end to the second end. The swiveling mechanism allows the connection member to rotate relative to a non-rotatable portion of the second end, the rotation being about a second end axis that extends in the forward direction. The swiveling mechanism limits rotation to 10 degrees. When detached from the bicycle the first end can be grasped by a user so the trailer can be used as a cart.

  • Publication number: 20190144063
    Abstract: An integrated rack connection assembly detachably attached to the front or rear portion of the bicycle. The integrated rack connection assembly includes tube clamp assembly, platform, a bracket, side frame extension and top frame extension. The tube clamp assembly includes a plurality of tubes integrated with a plate for an attachment at the front portion of down tube or with the rear portion of a seat tube. The down tube or seat tube is clamped with tube clamp assembly by utilizing screws. The platform to carry basket or bags is placed between the plurality of tubes of the tube clamp assembly in a horizontal position by flipping it when used in front or rear of the bicycle. The seat tube and the down tube of a bicycle are positioned in opposite angle. While attached, the seat or down tube extends into a rack to distribute weights of baskets or bags.

  • Publication number: 20180370590
    Abstract: Disclosed is an apparatus to utilize a universal hitch to detachably attach a bicycle with a trailer to carry loads. The apparatus comprises a universal hitch, tow arm, and rolling kickstand. The universal hitch attached to a bicycle rack either connected to the seat tube of a bicycle or an existing bicycle rear rack bicycle to detachably attach the bicycle with a trailer to carry one or more loads. The universal hitch utilizes a swiveling mechanism to support dynamics of the bicycle without disrupting the dynamics of the bicycle. The tow arm connects the universal hitch with the center of the trailer to block a lateral movement of the trailer and the bicycle up to 10 degrees by utilizing a swiveling mechanism. The swiveling mechanism prevents the trailer from tipping and sustains the dynamics of the bicycle in lateral movement. The rolling kickstand comprises a braking mechanism to park the trailer on a horizontal surface and ride the trailer as a cart.
