Abstract: A securing apparatus that releasably secures two or more mechanical elements is provided. The securing apparatus may be attached to one mechanical element and include abutment surfaces that abut at least one additional mechanical element. Forces exerted by the at least one additional mechanical element and the securing apparatus on each other serve to maintain the securing apparatus in an engaged position. The securing apparatus may include a locking member that includes a protruded portion that extends at least partially beneath the securing apparatus and at least one mechanical element. A pull-ring may be provided to rotate the locking member and release the mechanical elements being secured.

Abstract: A self-locking mechanism includes a first body member that rotates relative to a second body member, a lock lever rotatably coupled to the first body member and a biasing element that biases the rotation of the lock lever in a latching direction. The lock lever includes a cam portion that includes a cam surface configured to interface with a latch element on the second body member. The cam surface slidably engages the latch element and is configured so that the sliding engagement between the cam surface and the latch element causes the body members to be drawn together when the lock lever is rotated in the latching direction.

Abstract: A foldable bicycle includes a central portion of the frame, which defines the bicycle's geometry, that is substantially rigid. That is, the down tube, seat tube, top tube and bearing tube are substantially fixed relative to each other. Another feature of the foldable bicycle is that the front wheel can be folded into a position between the down tube, which is comprised of two tubes. Yet another feature is a tandem bicycle configuration that does not extend the length of the frame or the wheelbase.

Abstract: Goggles having handless pivotable lenses are provided. The goggles include at least one pair of lenses and a frame. The frame has a chin strap attached thereto. The chin strap enables a wearer to rotate the lenses such that the wearer may maintain the goggles placed on his or her head while not looking through the lenses. The chin strap is positioned underneath the wearer's chin. When the wearer does not wish to use at least one pair of lenses, the wearer opens his or her mouth to rotate the lenses. A linkage assembly operably coupled to the lenses and chin strap operate to rotate the lenses when the wearer opens his or her mouth. When the wearer closes his or her mouth, a spring provided in the linkage assembly facilitates rotation of the lenses back to an original position.

Abstract: In the riding mode, the folding bicycle has the same geometry that defines the riding characteristics and ergonomics in a usual bicycle, and has in the storage or portable mode the dimensions that fit into the trunks of small-sized cars, while allowing folding without the use of tools and in riding mode having no gaps between the detachable parts. The bicycle has the front fork (4) with the fork blades (6) bent forward and equipped with two backwards-pointing swing-arms (7), which hold the front wheel (3) in such a way that its position remains the same as in a usual bicycle and can be adjusted to riding preferences. The swing-arms (7), which are attached to the fork blades (6), rest on the end parts (13) and are bound by the springs (14). In the riding mode, the springs (14) keep the swing-arms (7) constantly pressed against the end parts.

That is, the down tube, seat tube, top tube and bearing tube are substantially fixed relative to each other. Another feature of the foldable bicycle is that the front wheel can be folded into a position between the downtube assembly, which is comprised of two tubes. Another feature is that a ratio of distances between and among tubes of the foldable bicycle is within a predetermined range.
