Abstract
A closable band includes a strap and a clasp. The strap is made of a material having a substantial coefficient of static friction when its ends overlap and contact each other. The clasp is formed with a base portion and an upper portion which are connected by a hinge. A latch secures the free edges of the base portion and the upper portion together. When the band is assembled by overlapping the ends of the strap and securing the clasp around the overlapped ends of the strap, the base portion and the upper portion provide a clamping force on the overlapped ends.
Claims7
A closable band comprising:
- a strap having first and second longitudinal ends and made of a material having a coefficient of static friction sufficient to resist longitudinal forces when the ends are overlapped and in contact with each other;
- and
- a clasp formed as a single element and comprising:
- a base portion having hinged and free ends;
- an upper portion having hinged and free ends;
- a hinge connecting the hinged end of the base portion and the hinged end of the upper portion;
- and
- means for securing the free end of the upper portion to the free end of the base portion by overlapping and contacting the ends of the strap and closing the clasp around the ends of the strap to move the base portion and the upper portion toward each other to provide a clamping force on the strap ends thereby to secure together the strap ends without materially deforming the strap ends such that the assembled band will not separate when subject to longitudinal forces that are less than 20N and the assembled band will separate when subject to forces greater than 80N.
An animal collar comprising:
- a substantially flat strap having first and second longitudinal ends and made of a material having a coefficient of static friction sufficient to resist longitudinal forces when the ends are overlapped and in contact with each other, wherein the strap is impregnated with an insecticide;
- and
- a clasp formed as a single element and comprising:
- a base portion having hinged and free ends, and an inner surface which contacts the strap ends when the strap is closed, wherein at least part of the inner surface is textured;
- an upper portion having hinged and free ends, and an inner surface which contacts the strap ends when the strap is closed, wherein at least part of the inner surface is textured;
- a hinge connecting the hinged end of the base portion and the hinged end of the upper portion;
- and
- means, comprising a latch which is repeatably openable and closable, for releasably securing the free end of the upper portion to the free end of the base portion by overlapping and contacting the ends of the strap and closing the clasp around the ends of the strap to move the base portion and the upper portion toward each other to provide a clamping force on the strap ends thereby to secure together the strap ends without materially deforming the strap ends such that the assembled collar will not separate when subject to longitudinal forces less than 20N and will separate when subject to forces greater than about 80N.
