Opening and closing apparatus
First Claim
1. An opening and closing apparatus comprising:
- a body portion including a gate;
a closure provided at the body portion and capable of opening and closing the gate;
a first pressure sensor disposed along a peripheral edge of at least one of the gate and the closure, the first pressure sensor including a curved portion;
a second pressure sensor disposed between the peripheral edge and the curved portion of the first pressure sensor; and
a control apparatus that controls opening and closing of the closure in accordance with operation of at least one of the first pressure sensor and the second pressure sensor.

Abstract
An opening/closing apparatus including a trapping detection structure which reliably implements detection of trapping of foreign objects, even at a structure at which an outer peripheral edge of a moving body or an inner peripheral edge of an opening includes corner portions with small radii of curvature. A pressure sensor which detects external forces from directions intersecting a length direction thereof is provided at an outer periphery portion of a back door. However, at a corner portion, at a lower end portion of a door side portion or the like, the pressure sensor is provided with a large curvature such that the pressure sensor keeps distant from the corner portion. In place thereof, another pressure sensor, with a facing pair of electrode sheets, is provided along the corner portion. When one or more of these pressure sensors detects an external force, the back door is moved for opening.
