1. An apparatus for clamping a pair of straps, comprising:
- a main body defining a passageway between-an-open entrance and an open exit end of the main body for receiving a pair of straps therethrough, the main body defining an aperture therein; and
a clamping member which is rotatable within said aperture between a first position in which it is adapted to clamp a pair of straps between a bottom surface or a peripheral side surface of the clamping member and the main body and a second position in which the clamping member is adapted to permit a pair of straps to be moved through said passageway, wherein the clamping memberis a cylindrical member having a cam around it, the cam having a ramped surface extending between at least one peak and at least one valley of the cam, and wherein the main body has an interior surface having a projection which engages the ramped surface of the cam, wherein the projection engages the peak of the cam in said first position and wherein the projection engages the valley of the cam in said second position.

Abstract
A strap divider for diverging a pair of straps which are disposed one on top of the other into a Y configuration which may be used for the chin straps of a bicycle helmet. The strap divider includes a main body which receives the pair of straps therethrough, and a rotatable clamping member which can be rotated from a position where the straps are clamped in place to an open position where the straps may be adjusted. In one embodiment, the rotatable member includes a cam around its circumference which cooperates with a projection in the main body for adjusting the clamping member between the open position and the locked position as the clamping member is rotated.

13. An apparatus in combination with a pair of straps, comprising:
-
a main body defining a passageway between an open entrance end and an open exit end of the main body, the main body comprising a top wall defining an aperture therein, a bottom wall and a pair of side walls joining the top wall to the bottom wall, wherein the width of the main body as measured between said side walls increases in the direction from said entrance end to said exit end; a pair of straps disposed and aligned one on top of the other which are received through said open entrance end, the straps diverging away from each other out from said open exit end of the main body; and a clamping member which is rotatable within said aperture in the top wall between a first position in which clamps said pair of straps between the member and the main body and a second position wherein said straps may be moved through said passageway. - View Dependent Claims (14, 15, 16)

17. An apparatus for clamping a pair of straps, comprising:
-
a main body defining a passageway between an open entrance and an open exit end of the main body for receiving a pair of straps therethrough, the main body including a top wall and a bottom wall, the top wall defining a first aperture therein and the bottom wall defining a second aperture therein, the second aperture having a perimeter with a serrated edge; and a clamping member which is rotatable within said first aperture between a first position in which it is adapted to clamp a pair of straps between a bottom surface or a peripheral side surface of the clamping member and the serrated edge of the second aperture and a second position in which the clamping member is adapted to permit a pair of straps to be moved through said passageway.
