Disclosed herein is an adjustable cup holder for holding a beverage container. The adjustable cup holder includes a body, a base configured to support the weight of a beverage container, an adjustable diameter ratchet strap configured to accommodate a diameter of the beverage container, and a connector. The holding portion of the cup holder may be connected to the body via a first hinge configured such that the beverage container holding portion is rotatable relative to the body about an axis to allow beverage container holding portion to hold the beverage container relatively level. The holding portion of the cup holder may be connected to the body via a hinge configured such that the beverage container holding portion is pivotable relative to the body about an axis from a use position to a stowed position.

A cup holding apparatus and a serving robot including the cup holding apparatus are provided. The cup holding apparatus may include a first support member configured to support a cup and having a lower surface that has convex shape; a second support member having an upper surface that has a concave shape and faces the lower surface of the first support member; a third plate provided between the first support member and the second support member; and a plurality of rolling members that pass through and are rotatably supported by the third plate, and contact the lower surface of the first support member and the upper surface of the second support member.

A self leveling picture frame assembly for automatically leveling a picture includes a picture frame defining a viewing space to display a picture. An insert is insertable into the picture frame to retain the picture in the picture frame. A leveling chamber is integrated into the insert and the leveling chamber contains a leveling fluid. The total quantity of leveling fluid is substantially less than a volume of the leveling chamber thereby facilitating the leveling fluid to travel freely in the leveling chamber. Moreover, the leveling fluid collects in the lowest point of the leveling chamber when the picture frame is hung on a vertical support surface. In this way the leveling fluid can level the picture frame on the vertical support surface.

The invention is an insulated self-righting cup holder. It is not simply just a gyroscopic cup holder. This is a new application of the concept of using a gyroscope to hold an open beverage using a self-contained, insulated container formed by a fabric cover mounted to a wide, stable, non-slip base. The invention does not require physical mounting or connection to a fixed object or surface. It can be placed on any surface inclined up to fifteen degrees from the horizontal. A full sixteen-ounce open beverage can be held by the invention while the invention is sitting on that surface without fear that it will topple over and spill the beverage . . . making it ideal for camping or other outdoor activities. The fabric cover can be printed with any design. The invention is lightweight, portable, and reusable.

A cup holder can easily be assembled by a user and attached to portable luggage, such as along a horizontal handle of the luggage. The cup holder can pivot to keep the beverage upright while allowing the user to keep both hands free from the need to carry the beverage. The cup holder can be unassembled into a flattened sheet configuration for easy storage or disposal. The cup holder can include hooked ends for securing to the luggage and a hanging, size adjustable beverage pocket for receiving the beverage container therein.

A self-leveling picture frame apparatus for automatically leveling pictures hung on a wall includes a frame body having an upper portion, a lower portion, a left portion, and a right portion defining a frame aperture. A leveling liquid is coupled within a leveling cavity of the frame body. The leveling cavity is shaped to direct the leveling liquid towards a midline of either the upper portion, the lower portion, the left portion, or the right portion depending on which portion is lowest. A transparent front cover is coupled to the frame body. The front cover is coupled to a front face of the frame body within the frame aperture. A back cover is coupled to a back face of the frame body over the frame aperture.

A storage box includes an outer cylinder and a frame. The outer cylinder has a sidewall with an opening. The frame is disposed inside the outer cylinder, and has a rotatable connection with the outer cylinder. A space between a surface of the frame and the sidewall of the cylinder forms a storage member. As the frame rotates relative to the outer cylinder, the opening and the storage member alternates between a first relative position and a second relative position.

Attachment mechanisms that enhance and broaden the usefulness of a basic gimbaled beverage container holder are needed. The mechanisms developed are configured to form a rigid attachment to an external object, such as luggage handles; stroller handles; bicycle handles; boat railings; car/truck air vents etc. in order to give the user a sense of stability for the combined unit. Three basic attachment enhancements are added to the outer ring of the gimbaled cup holder. They are: 1) A set of rigid Arms (*removable and exchangeable for different size luggage handles) that grab around vertical luggage handles and hold the gimbaled cup holder secure. 2) a Slide mechanism on one of the handles that hold the gimbaled cup holder secure to one handled luggage. 3) A T-Bar Clip on the outer ring of the gimbaled cup holder that securely locks a variety of attachment devices (*such as a vertical and horizontal bar attachment mechanisms; a car/truck air vent attachment mechanism, etc.,) to most external objects or transport devices.
