Abstract
A finger guard for blocking a pinch point in a system including a base, at least one roller pin coupled to the base, a roller rotatably supported on the at least one roller pin, and a movable structure supported on the roller and movable over the roller relative to the base. The finger guard includes a side wall extending from a front wall, whereby the side wall and the front wall at least partially define a cavity for receiving the roller. The finger guard further includes a roller pin opening extending through the front wall for receiving the roller pin. A fastener may be coupled to the roller pin to couple the finger guard to the base.
Claims12
An apparatus comprising:
- a base;
- a roller pin coupled to the base;
- a roller rotatably supported on the at least one roller pin;
- a movable structure supported on the roller and movable over the roller relative to the base;
- a finger guard comprising;
- a front wall having an apex at a bottom of the finger guard and a base edge at the top of the finger guard,
- a side wall extending from the front wall, whereby the side wall, the front wall and the base at least partially define a cavity, and
- a roller pin opening extending through the front wall,
- the roller being at least partially disposed in the cavity with the roller pin extending through the roller pin opening, wherein a top of the roller extends above the base edge of the front wall for supporting the movable structure;
- and
- a fastener coupled to the roller pin to couple the finger guard to the base,
- wherein the side wall extends under a perimeter of the base to prevent access to the cavity from the bottom of the finger guard.
An apparatus comprising:
- a base;
- a roller pin coupled to the base;
- a roller rotatably supported on the at least one roller pin;
- a movable structure supported on the roller and movable over the roller relative to the base;
- a finger guard comprising;
- a front wall having an apex at a bottom of the finger guard and a base edge at a top of the finger guard,
- a side wall extending from a perimeter of the front wall and toward the base, the sidewall extending around a first side, a bottom, and a second side of the finger guard, whereby the side wall, the front wall and the base at least partially define a cavity, and
- a roller pin opening extending through the front wall,
- the roller being at least partially disposed in the cavity with a top of the roller extending above the base edge of the front wall for supporting the movable structure and with the roller pin extending through the roller pin opening;
- and
- a fastener coupled to the roller pin to couple the finger guard to the base, whereby a front wall of the movable structure is positioned to pass in front of the front wall of the finger guard as the movable structure is moved over the roller relative to the base,
- wherein the side wall extends under a perimeter of the base to prevent access to the cavity from the bottom of the finger guard.
