Abstract

The invention provides a clasping device that is simple to utilize and remove, and comprises a minimum number of operating components, yet is capable of efficiently performing a clasping function. A base is provided having first and second ends with an object-receiving surface disposed between the ends. A hasp, which preferably is of inextensible but flexible material, has first and second ends operatively cooperating with the base first and second ends, and has an object-receiving surface disposed between its ends. A conical screw acts between the base and the hasp for, when it is advanced, effecting relative movement between the hasp and base object-receiving surfaces to cause the object to be tightly clasped therebetween. The first and second ends of the base and hasp may take a wide variety of forms depending upon the particular nature of the hasp itself, the object to be held, and the environment.

Dependent claims

A clasping device for releasably tightly clasping an object, comprising:

base means;
hasp means;
and
conical screw means;
said base means having:
means defining an exterior surface thereof for receiving an object thereon;
a first end and a second end disposed on opposite sides of said surface, said first end having:
means defining an opening therein having an area substantially larger than at least the smallest cross-sectional area of said conical screw means;
and edge means having a thickness for engaging within the grooves of said conical screw means and allowing longitudinal displacement of said conical screw means upon rotation thereof when in engagement with said edge means;
and
said hasp means having:
means defining an exterior surface thereof for receiving an object thereon;
a first end and a second end of said hasp means disposed on opposite sides of said surface, said hasp means second end operatively pivotally mounted to said base means second end;
said hasp means first end having curved surface means for engaging said conical screw means so that as said conical screw means passes through said base means first end opening, with said base and hasp means second ends in operative engagement, it engages said edge means and said hasp means first end curved surface, and as it is rotated it moves longitudinally of said edge means and moves said edge means and curved surface further apart, which in turn moves said hasp and base means object-receiving surfaces closer together;
and
said hasp means being so constructed that as said hasp means first end curved surface means is engaged by said conical screw means a bending of said first end takes place as said object-receiving surface means is straightened, effecting tightly clamping of an object received thereby.

a first end and a second end of said hasp means disposed on opposite sides of said surface, said hasp means second end operatively pivotally mounted to said base means second end;
said hasp means first end having curved surface means for engaging said conical screw means so that as said conical screw means passes through said base means first end opening, with said base and hasp means second ends in operative engagement, it engages said edge means and said hasp means first end curved surface, and as it is rotated it moves longitudinally of said edge means and moves said edge means and curved surface further apart, which in turn moves said hasp and base means object-receiving surfaces closer together;
said base means second end comprising a notched plate, and said hasp means second end including slot means formed therein for defining a slot having a thickness greater than the width of said notched plate and a slot end for engaging a notch so said notched plate;
and
said base means first end comprising a plate having a notch formed in a portion thereof formed on the opposite side of said first end opening as said base means object-receiving exterior surface, said hasp means first end including a slot end received in said notch.
