Abstract
A fastening device is structured so that one half thereof is symmetrical with the other and includes a casing, with a pair of inwardly folded portions, and a pair of symmetrical block-members, each having a bar-member and accommodated within the casing such that one end of each block-member is respectively outwardly biased toward the lateral open ends of the casing. Respective end portions of strings or the like are wound around the respective bar-member and respectively abut the respective folded portions as long as the respective ends of the block-members remain outwardly biased and are not pushed inwardly by a user.
Claims13
A fastening device to be used with an object having at least one string which fixes the string in position in relation to an object when the string is affixed by the fastening device, said device comprising:
- a casing having a first and second longitudinal sides and having two lateral open ends, said longitudinal sides being oppositely positioned with respect to one another;
- said first longitudinal side having a central bore through the center thereof;
- said second longitudinal side having two first apertures therethrough, each of said first apertures being respectively positioned between the axis of said central bore and one of said lateral open ends;
- a pair of block members, said block members being oppositely slidably positioned within said casing and respectively having end portions which respectively project from said lateral open ends;
- each of said block members having a chamber therein and having a first opening therein which communicates with said chamber, said first opening being substantially aligned with one of said first apertures and communicating therewith;
- said block members having two bar members respectively fixedly positioned in said chamber of each of said blocks, each of said bar members extending in a direction substantially transverse to the longitudinal direction of said casing, each of said block members having a shoulder extending outwardly from said central bore for abutting the outer periphery of said central bore for limiting outward movement of the corresponding block member with respect to said casing;
- a biasing means positioned within said casing for biasing said block members away from one another;
- and
- said first longitudinal side having two inwardly projecting engaging portions, each of said engaging portions being respectively operatively associated with a corresponding one of said bar members for, when said block members are biased by said biasing means, abutting and affixing a corresponding string, threaded through one of said first apertures and said first opening associated with a corresponding one of said block members and wound at least partially around the associated one of said bar members, against the associated said one of said bar members and thereby preventing the corresponding string from substantial movement in the longitudinal direction thereof with respect to the corresponding block member and thereby fixing the string in position in relation to the object.
