Abstract
An adjustable collar stay has two components: a) a housing, and b) a movable piece having a wider head and elongated portion, the elongated portion adapted for slidably moving within the housing. The wider head is at least one cross-section disposed perpendicular to the point of entry (portal) into the housing, preventing its entry thereto. A spring-loaded pin, situated within the housing, engages with a pit, cut into the side of the elongated region of the movable piece. By grasping the head and pushing it transverse to the direction of the housing, one dislodges the pin from a pit, and moves the movable piece with respect to the housing, in order to elongate or shorten the entire device.
Claims12
An adjustable collar stay, comprising:
- an elongated housing with a hollow elongated interior space having a portal at one side forming a hollow interior track terminating at said portal;
- a movable piece comprising a unitary head and elongated portion,
- said elongated portion adapted to slidably move within said hollow interior track of said elongated housing
- said unitary head, at a point of connection with said elongated portion, having a width greater than that of said elongated portion and of said hollow interior track of said housing, said greater width preventing movement of said unitary head into said hollow interior track;
- wherein said unitary head of said movable piece is triangular, with a base thereof having said width greater than said hollow interior track, and a tip, opposite said base, having a width narrower than said hollow interior track;
- a center of said base being offset with respect to said elongated portion, such that a portion of said base of said unitary head extending from said one of said two narrow sides divided by said pits is longer than a portion of said base of said unitary head extending from said other of said two narrow sides;
- and
- a spring-loaded pin, rotatably fixed at a first end thereof directly to said elongated housing and extending into a pit of said plurality of pits at a second end thereof.
An adjustable length device, comprising:
- a housing with a hollow elongated interior;
- a pin rotatably fixed to a protrusion extending into said hollow elongated interior;
- a slidable member adapted to slide within said hollow elongated interior in a manner such that said slidable member has a broad side parallel to at least one corresponding side of said hollow elongated interior in a resting position and a unitary head which is triangular, with a base thereof having said width greater than said hollow interior track, and a tip, opposite said base, having a width narrower than said hollow interior track, a center of said unitary head being offset with respect to said elongated portion such that a portion of said base of said unitary head extending from said one of said two narrow sides divided by said pits is longer than a portion of said base of said unitary head extending from said other of said two narrow sides;
- and a plurality of pits cut into one of said two narrow sides of said slidable member to divide said one of said two narrow sides into segments, each of said plurality of pits adapted to engage an end of said pin opposite a side of said pin fixed to said protrusion.
