An article of protective apparel for placement on and protection of a portion of the body of a user includes a protective shell and bi-directional device that receives a first and second line that each extend to the shell. Rotation of a control handle of the bi-directional device causes portions of the lines to be drawn into the device, thereby tightening the protective shell about the user. Optionally, the article is a helmet for having an adjustable chin strap that is capable of being tightened by manual rotation of the control handle of the device. Optionally, the article of protective apparel is capable of being loosened by manual positioning of the control handle into a release position.

An article of adjustably fitted protective apparel includes a vest and an adjustable tensioning system for selective tensioning of the vest into a snug fit on a body of a wearer of the vest. The adjustable tensioning system includes a rotary tension adjuster disposed on the vest and including a housing and a first spool disposed within the housing, and a tensioning line extends from the housing. The tensioning line is attached directly or indirectly to the vest. A portion of the tensioning line is configured to be wound upon the first spool during manipulation of the rotary tension adjuster in a first rotational direction thereof. Winding of the portion of the first tensioning line draws together first portions of the vest for providing a snug fit of the first portions.

A method of drawing lines into a housing includes: rotating a dial in a first rotational direction of the dial such that a first spool located in an interior of the housing is mechanically rotated in a first rotational direction thereby winding a first line thereabout; and rotating the same dial in a second rotational direction opposite to the first rotational direction such that a second spool located in the interior of the housing is mechanically rotated in a first rotational direction thereby winding a second line thereabout. The rotating of the same dial in the second, opposite rotational direction does not result in unwinding of the first line from the first spool, and the rotating of the same dial in the first rotational direction does not result in unwinding of the second line from the second spool.

A device for independently tensioning lines includes: (a) a housing; (b) a control handle extending from the housing and configured for manual rotation by a hand of a person; (c) a first line extending from the housing; and (d) a second line extending from the housing. The control handle is manually rotatable by hand about an axis in a first rotational direction, whereby at least a portion of the first line is drawn into the housing when the control handle is rotated in the first rotational direction. The handle also is manually rotatable by hand about the axis in a second rotational direction, whereby at least a portion of the second line is drawn into the housing when the control handle is rotated in the second rotational direction. The rotational direction is opposite the first rotational direction.

A stroller for carrying a child in a plurality of configurations includes a frame having a frame base defining a forward-facing direction and a rearward-facing direction and at least two side members attached at opposite sides of the frame base. The stroller further includes a plurality of wheels connected to the frame and a seat arranged generally above a platform attached to the frame and configured for selective rotation, relative to the frame base, about an axis generally perpendicular to the platform. The seat may be selectively rotated between a forward-facing position and a rearward-facing position. The seat may further be adapted to be selectively reconfigurable between a seated configuration and a standing configuration.

A modular table tennis game includes a plurality of paddles, a table tennis ball, and an adjustable table, or multiple adjustable tables. The tables may be mounted on a support system such as a tripod or other support structure that allows the tables to be adjusted in height and tilt. The top of the tables may have an opening or openings larger than the table tennis ball penetrating therethrough.

An apparatus for securely holding and protecting a layout of elements includes a portfolio having a first cover and a first overlay. The first overlay and the first cover are releasably cohered together, preferably utilizing magnetic forces. A loose arrangement of elements can be secured to a work surface of the first cover using the first overlay for safe storage and transport. The apparatus is used in rubber stamping design, stained-glass design, and quilting design.

A writing instrument for use by a grader comprises an elongate, tubular housing, a writing component secured within the housing and operative to make marks on a surface, and a calculation assembly comprised of electronic components. The calculation assembly is retained within the housing and includes a plurality of data entry devices for entering data used to calculate a grade, the data entry devices being accessible by the grader through an exterior surface of the housing; a processing device programmed to receive data from the plurality of data entry devices and calculate the grade based on the entered data by performing division; and a display component for displaying to the grader the grade calculated by the processing device. A method of grading comprises using the writing instrument.
