US 2026/0194093 A1 · CLAMP APPARATUS

Abstract

A clamp apparatus is disclosed for securing a sleeve to an arm, such as a turnstile arm, while limiting relative rotation and resisting torsional and impact loads. The clamp apparatus includes an annular flange having first and second apertures and an interior surface extending between the apertures. One or more screws extend through the flange from an exterior surface toward the interior surface and contact respective clamp pads positioned within recesses formed in the interior surface. Tightening the screws drives the clamp pads into engagement with the arm, distributing clamping forces over a contact area larger than the screws alone. In some examples, a pad driver rotatably decouples the screws from the clamp pads to reduce friction and wear. The flange may include threads configured to mate with a sleeve, and opposing clamp apparatuses may be used to resist loosening under alternating torque.

Dependent claims

A clamp apparatus comprising:

an annular flange having a first end defining a first aperture and a second end defining a second aperture;
an exterior surface of the annular flange, and an interior surface of the flange that extends from the first aperture to the second aperture;
a first screw extending through the annular flange from the exterior surface toward the interior surface and contacting a first clamp pad positioned within a first recess formed in the interior surface;
and
a second screw extending through the annular flange from the exterior surface toward the interior surface and contacting a second clamp pad positioned within a second recess formed in the interior surface, wherein the first screw and the second screw being angularly separated from one another by 70 degrees to 120 degrees about a central axis of the annular flange.
